FORM OF INVESTOR RIGHTS AGREEMENT 

This Investor Rights Agreement (this “Agreement”) is made as of October 31, 2019 (the

WHEREAS, the Investor and the Company have entered into that certain Investment Agreement, dated as of October 3, 2019 (the
“Investment Agreement”), pursuant to which Investor has agreed to purchase, subject to the satisfaction and/or waiver of the conditions set forth therein, up to an aggregate of 125,000 shares of Series A Convertible Preferred
Stock, par value $0.01 per share, of the Company (the “Preferred Stock”); and 
 WHEREAS, it is a condition
precedent to Investor’s obligation to purchase, and the Company’s obligation to sell, such Preferred Stock that the Parties enter into this Agreement to provide for certain rights and obligations of the Parties following the closing of the
transactions contemplated by the Investment Agreement and the other Transaction Documents. 
 NOW, THEREFORE, in consideration of the
mutual covenants contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties to this Agreement hereby agree as follows: 

Section 1. Board of Directors. 

(a) Subject to the terms and conditions of this Agreement (including, in each case, the requirements and limitations set forth in this
Section 1), from and after the Effective Date, until the first day on which the Investor Ownership Threshold is no longer satisfied (such day, the “Fall Away Date”): 

(i) the Investor shall have the right, but not the obligation, to designate one Person to be nominated for each election of
members to the Board (a “Nominee”) by giving written notice to the Company on or before the time such information is reasonably requested by the Board or the Nominating & Corporate Governance Committee (the
“Governance Committee”) for inclusion in a proxy statement for a meeting of stockholders, together with all information about the Nominee as shall be reasonably requested by the Board or the Governance Committee in order to
make the determination referred to in Section 1(d), each of which request by the Board or the Governance Committee, as applicable, must be made no later than the date that is thirty (30) days prior to the filing of
such proxy statement; provided, however, the initial Nominee shall be appointed as set forth in Section 1(b); 

(ii) the Company shall, to the fullest extent permitted by applicable Law and subject to the Investor’s compliance with
this Section 1, (A) take such actions as may be necessary and desirable to ensure that: (1) the Nominee is included in the Board’s slate of nominees to the stockholders of the Company for each election of members
of the Board, and that the Board recommend that the Company’s stockholders vote for each of the director nominees included in such slate, including the Nominee; and (2) the Nominee is included in the proxy statement prepared by management
of the Company in connection with soliciting proxies for every meeting of the stockholders of the Company called with respect to the election of members of the Board, and at every adjournment or postponement thereof, and on every action or approval
by written consent of the stockholders of the Company or the Board with respect to the election of members of the Board; and (B) undertake to promote the Nominee and his or her election to the Board, and solicit votes therefor, to the same
degree as that undertaken to promote and solicit votes for the other nominees and their respective election to the Board; 

  
 1 













 (iii) if a vacancy occurs because of the death, disability,
disqualification, resignation, or removal of an Investor Director or for any other reason, the Investor shall be entitled to designate such person’s successor, and the Company will, as promptly as reasonably practicable following such
designation, take all necessary and desirable actions within its control, to the fullest extent permitted by applicable Law, such that such vacancy shall be filled with such successor Nominee; 

(iv) if a Nominee is not elected because of such Nominee’s death, disability, disqualification, withdrawal as a nominee or
for any other reason, the Investor shall be entitled to designate promptly another Person to the Board and the Company will take all necessary and desirable actions within its control such that the director position for which such Person was
nominated shall not be filled pending such designation or the size of the Board shall be increased by one and such vacancy shall be filled with such successor Nominee as promptly as practicable following such designation; 

(v) as promptly as reasonably practicable following the request of any Investor Director, the Company shall enter into an
indemnification agreement with such Investor Director, in the form entered into with the other members of the Board; the Company shall pay the reasonable, documented
out-of-pocket expenses incurred by the Investor Director in connection with his or her services provided to or on behalf of the Company, including attending meetings or
events attended explicitly on behalf of the Company at the Company’s request; provided that such payments shall be consistent with the Company’s policy for paying such expenses of other directors of the Company; and 

(vi) upon the occurrence of any of (A) the Investor Ownership Threshold ceasing to be satisfied for a period of thirty
(30) consecutive days, or (B) the Investor Director failing at any time to satisfy any of the conditions set forth in Section 1(d), then the Investor shall cause the Investor Director to immediately resign from
the Board; provided that in the event the Investor Director is required to resign from the Board pursuant to the foregoing clause (B), the Investor will be permitted to designate a replacement Nominee (which replacement Nominee will also be
subject to the requirements of Section 1(d)). 
 (b) Following notice from the Investor identifying the initial
Nominee, the Company and the Board shall, subject to the requirements and limitations set forth in this Section 1, as promptly as reasonably practicable following delivery of such notice, take all necessary and all
desirable actions within its control, to the fullest extent permitted by applicable Law, to appoint such initial Nominee as a director of the Board. 

(c) Each Investor Director will hold office until his or her term expires and such Investor Director’s successor has been duly elected and
qualified or until such Investor Director’s earlier death, disability, disqualification, resignation, or removal. 
 (d) Notwithstanding
anything to the contrary contained herein, neither the Company nor the Board shall be under any obligation to nominate or appoint to the Board, or solicit votes for, any Person pursuant to Section 1(a) in the event that the Board reasonably
determines that (i) the election of such Person to the Board would cause the Company to not be in compliance with applicable Law or stock exchange listing standards, (ii) such Person has been the subject of any event required to be disclosed
pursuant to Items 2(d) or 2(e) of Schedule 13D under the Exchange Act or Item 401(f) of Regulation S-K of the 1934 Securities Act (for the avoidance of doubt, excluding bankruptcies) involving an act of moral 

  
 2 













 turpitude by such individual or is subject to any order, decree or judgment of any Governmental Entity
prohibiting service as a director of any public company, (iii) such Person fails to complete reasonable and customary onboarding documentation, including providing reasonably required information to the Company, in each case to the extent such
requirements are consistent with those applicable to the other members of the board of directors of the Company, (iv) such Person does not qualify as an “independent director” of the Company under clause (b) of Rule 303A(2) of the NYSE
Listed Company Manual, (v) such Person is an officer or employee of Investor or any of its subsidiaries or their respective successors or its or their respective subsidiaries, or (vi) such person is as of such time a director, officer or
employee of an Activist. In the event Nominee is not nominated to the Board as a result of a failure to satisfy any of the requirements described in clauses (i) through (vi) of the immediately preceding sentence or for any other reason, until the
Fall Away Date, the Investor will be permitted to designate a replacement Nominee (which replacement Nominee will also be subject to the requirements of this Section 1(d)). 

(e) For so long as the Investor Director is a member of the Board in accordance with and subject to the terms of this Agreement, subject to
applicable Law, the listing standards of the Principal Stock Exchange and the limitations set forth in Section 1(e), the Company will offer the Investor Director an opportunity to, at Investor’s option, either
(i) be a member of all committees of the Board that currently exist and any special, executive, or other committees of the Board authorized by the Board after the Effective Date, or (ii) attend (but not vote) at the meetings of each such
committee as an observer; provided, however, that the Investor Director shall not have an opportunity to be a member of the Compensation Committee of the Board unless so requested by the Board. If the Investor Director fails to satisfy
the applicable qualifications under applicable Law or stock exchange listing standards to be a member of any such committee of the Board, then, subject to the limitations set forth in Section 1(e), the Board shall offer the
Investor Director the opportunity to attend (but not vote) at the meetings of such committee as an observer, as well as the right to receive all written materials made available to the members of such committee. 

(f) Notwithstanding anything to the contrary contained herein, if the Board reasonably determines in good faith, after consultation with the
Investor Director and in accordance with any other applicable bona fide procedures the Board may have in place at any such time with respect to director conflicts generally, that (i) the appointment of the Investor Director on any committee of
the Board, or attendance as an observer, (ii) the discussions of the Board or any committee on which the Investor Director is a member or observer or (iii) the materials to be disseminated to the Board or any committee on which the
Investor Director is a member or observer, in each case, (A) would contain material and highly sensitive or competitive matters or other information that would give rise to a conflict of interest between the Company and the Investor Director,
or (B) would be a violation of the Board’s bona fide conflict policies (which policies shall have been made available to the Investor Director) (“Director Conflict”), then the Board shall be permitted to (1) in
the case of any appointment or observer right on a committee of the Board pursuant to Section 1(d), decline to appoint or provide observer rights to the Investor Director with respect to such committee, solely to the extent
necessary as a result of such Director Conflict, and (2) in all cases, require the Investor Director to, and in such event the Investor shall cause the Investor Director to, recuse himself or herself from such discussions solely to the extent
necessary as a result of such Director Conflict, and neither the Company nor the Board shall be required to disseminate such portions of such materials to the Investor Director solely to the extent necessary as a result of such Director Conflict.
Without limiting the generality of the foregoing, if the Investor Director is also a director of the Investor or any of its Affiliates, the Board shall be entitled to require the Investor Director to recuse himself or herself from those portions of
any discussions regarding any potential transaction, agreement or other arrangement between the Company or any of its Affiliates, on the one hand, and the Investor or any of its Affiliates, on the other hand.

 Section 2. Information and Access. 

(a) Subject in each case to Section 1(f), following the Effective Date until the Fall Away Date, the Company agrees
to provide the Investor Director with copies of all material, substantive materials provided to the Board and any committee thereof at substantially the same time as provided to the Directors of the Company or members of such committee. 

(b) Following the Effective Date and only for so long as the Investor Ownership Threshold is satisfied, the Company shall provide to Investor,
if and only if such information is prepared by the Company and its subsidiaries in the ordinary course of business for purposes unrelated to the requirements in this Section 2(b), the following information substantially
contemporaneously with the time such information is actually delivered to the Board (or, if not delivered to the Board, reasonably promptly following the completion of its preparation): 

(i) an unaudited consolidated balance sheet of the Company and its subsidiaries as at the end of such fiscal quarter and
unaudited consolidated statements of income and cash flows of the Company and its subsidiaries for such fiscal quarter, prepared in accordance with GAAP; and 

(ii) an audited consolidated balance sheet of the Company and its subsidiaries as at the end of such fiscal year and unaudited
consolidated statements of income and cash flows of the Company and its subsidiaries for such fiscal year, prepared in accordance with GAAP. 

(c) Investor’s rights under this Section 2 shall be subject, in each case, to Investor executing a customary
confidentiality agreement regarding any confidential information received from or regarding the Company, in substantially the form attached hereto as Exhibit A. 

(d) For the avoidance of doubt, nothing in this Section 2 will limit any rights of Investor or any of its Affiliates
under applicable Law. 
 Section 3. Registration Rights. 

(a) Shelf Registration. 

(i) Filing. The Company shall file, on or prior to the date that is six (6) months after the Effective Date, a
Registration Statement for a Shelf Registration on Form S-3 (the “Form S-3 Shelf”) or, if the Company is ineligible to use a Form S-3 Shelf, a Registration Statement for a Shelf Registration on Form S-1 (the “Form S-1 Shelf,” and together
with the Form S-3 Shelf (and any Subsequent Shelf Registration), the “Shelf”) covering the resale of the Registrable Securities on a delayed or continuous basis. The Company shall use
reasonable best efforts to cause the Shelf to become effective by the date that is sixty (60) days after the date that is six (6) months after the Effective Date. The Shelf shall provide for the resale of Registrable Securities from time
to time, and pursuant to any method or combination of methods legally available to, and requested by, the Investor. The Company shall maintain the Shelf in accordance with the terms hereof, and shall prepare and file with the SEC such amendments,
including post-effective amendments, and supplements as may be necessary to keep such Shelf effective and in compliance with the provisions of the Securities Act until such time as there are no longer any Registrable Securities. In the event the
Company files a Form S-1 Shelf, the Company shall use its reasonable best efforts to convert the Form S-1 Shelf (and any Subsequent Shelf Registration) to a Form S-3 Shelf as soon as practicable after the Company is eligible to use Form S-3. 

  
 4 













 (ii) Subsequent Shelf Registration. If any Shelf ceases to be
effective under the Securities Act for any reason at any time while Registrable Securities are still outstanding, the Company shall use all reasonable efforts to as promptly as is reasonably practicable cause such Shelf to again become effective
under the Securities Act (including obtaining the prompt withdrawal of any order suspending the effectiveness of such Shelf), and shall use all reasonable efforts to as promptly as is reasonably practicable amend such Shelf in a manner reasonably
expected to result in the withdrawal of any order suspending the effectiveness of such Shelf or file an additional registration statement as a Shelf Registration (a “Subsequent Shelf Registration”) registering the resale from
time to time by the Investor thereof of all securities that are Registrable Securities as of the time of such filing. If a Subsequent Shelf Registration is filed, the Company shall use all reasonable efforts to (i) cause such Subsequent Shelf
Registration to become effective under the Securities Act as promptly as is reasonably practicable after the filing thereof (it being agreed that the Subsequent Shelf Registration shall be an Automatic Shelf Registration Statement if the Company is
a Well-Known Seasoned Issuer) and (ii) keep such Subsequent Shelf Registration continuously effective and usable until there are no longer any Registrable Securities. Any such Subsequent Shelf Registration shall be on Form S-3 to the extent that the Company is eligible to use such form. Otherwise, such Subsequent Shelf Registration shall be on another appropriate form and shall provide for the registration of such Registrable
Securities for resale by the Investor in accordance with any reasonable method of distribution elected by the Investor. 

(iii) Requests for Underwritten Shelf Takedowns. At any time and from time to time after the Shelf has been declared
effective by the SEC, the Investor may request to sell all or any portion of its Registrable Securities in an underwritten offering that is registered pursuant to the Shelf (each, an “Underwritten Shelf Takedown”);
provided that the Company shall only be obligated to effect an Underwritten Shelf Takedown if such offering shall include either (x) securities with a total offering price (before deduction of underwriting discounts) reasonably expected
to exceed $25 million or (y) all remaining Registrable Securities. All requests for Underwritten Shelf Takedowns shall be made by giving written notice to the Company (the “Demand Shelf Takedown Notice”). Each
Demand Shelf Takedown Notice shall specify the approximate number of Registrable Securities proposed to be sold in the Underwritten Shelf Takedown and the expected price range (net of underwriting discounts and commissions) of such Underwritten
Shelf Takedown. The Investor shall have the right to select the investment banker(s) and manager(s) to administer the offering (which shall consist of one or more reputable nationally recognized investment banks), subject to the Company’s prior
approval which shall not be unreasonably withheld, conditioned or delayed. Notwithstanding the forgoing, the Investor shall be entitled to effectuate no more than three (3) Underwritten Shelf Takedowns pursuant to this Agreement. 

(b) Piggyback Takedowns. Whenever the Company proposes to register any of its securities, including a registration pursuant to any
registration rights agreement between the Company and holders of its securities (a “Piggyback Registration”), or proposes to offer any of its securities pursuant to a registration statement in an underwritten offering under
the Securities Act (together with a Piggyback Registration, a “Piggyback Takedown”), the Company shall give reasonably prompt written notice to the Investor of its intention to effect such Piggyback Takedown. In the case of a
Piggyback Takedown that is an underwritten offering under a shelf registration statement, such notice shall be given not less than five (5) Business Days prior to the expected date of commencement of marketing efforts for such Piggyback
Takedown. In the case of a Piggyback Takedown that is an underwritten offering under a registration statement that is not a shelf registration statement, such notice shall be given not less than five (5) Business Days prior to the expected date
of filing of such registration statement. The Company shall, subject to the provisions of Section 3(d) below, include in such Piggyback Takedown, as applicable, all Registrable Securities requested to be included by the
Investor within three (3) Business Days after sending the Company’s notice. Notwithstanding anything to the contrary contained herein: (i) the Company may determine not to proceed with any Piggyback Takedown upon written notice to the


  
 5 













 
Investor; provided, however, that nothing in this clause (i) shall impair the right of the Investor to request that such registration be effected pursuant to
Section 3(a) or 3(b); and (ii) the Investor may withdraw its request for inclusion by giving written notice to the Company of its intention to withdraw that registration; provided, however, that the
withdrawal shall be irrevocable and after making the withdrawal, the Investor shall no longer have any right to include its Registrable Securities in that Piggyback Takedown. If any Piggyback Takedown is an underwritten offering, the Company will
have the sole right to select the investment banker(s) and manager(s), acceptable to the Investor, for the offering. 
 (c) Priority.
If the Company determines after consultation with the managing underwriter in any underwritten Piggyback Takedown that was not initiated by the Investor pursuant to this Agreement, that less than all of the Registrable Securities requested to be
included in such underwritten offering can be sold in an orderly manner within a price range acceptable to the Company or the holders of the Company’s securities demanding such Piggyback Takedown pursuant to registration rights granted to other
holders of the Company’s securities, as applicable, then the Company shall include in such underwritten Piggyback Registration the number which can be so sold in the following order of priority: 

(A) first, the securities the Company and/or the holders of the Company’s securities, other than the Investor,
demanding such Piggyback Takedown pursuant to registration rights granted to such holders propose to sell; 
 (B)
second, the Registrable Securities requested to be included in such Piggyback Registration by the Investor (provided, that in no event shall the aggregate amount of securities of the Investor and the holders of the Company’s
securities demanding such Piggyback Takedown pursuant to registration rights granted to such holders included in the registration be reduced below thirty percent (30%) of the total amount of securities included in such registration); and 

(C) third, other securities requested to be included in such underwritten Piggyback Takedown. 

(d) Company Undertakings. Whenever Registrable Securities are registered or sold pursuant to this Agreement, the Company shall use all
reasonable efforts to effect the registration and the sale of such Registrable Securities as soon as reasonably practicable in accordance with the intended method of disposition thereof and pursuant thereto the Company shall as expeditiously as
possible: 
 (i) at least five (5) Business Days before filing a Registration Statement or Prospectus or any amendments
or supplements thereto, at the Company’s expense, furnish to the Investor copies of all such documents, other than exhibits or documents that are incorporated by reference, proposed to be filed and such other documents reasonably requested by
the Investor, which documents shall be subject to the review and comment of the counsel to the Investor (with respect to information regarding the Investor or the intended plan of distribution); 

(ii) notify the Investor of the effectiveness of each Registration Statement and prepare and file with the SEC such amendments
and supplements to such Registration Statement and the Prospectus used in connection therewith as may be necessary to keep such Registration Statement effective for a period ending on the date on which all Registrable Securities have been sold under
such Registration Statement or have otherwise ceased to be Registrable Securities, and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such Registration Statement during such period in
accordance with the intended methods of disposition by the sellers thereof set forth in such Registration Statement; 

  
 6 













 (iii) furnish to the Investor, and the managing underwriters, without
charge, such number of copies of the applicable Registration Statement, each amendment and supplement thereto, the Prospectus included in such Registration Statement (including each preliminary Prospectus, final Prospectus, and any other Prospectus

exhibits and other documents filed therewith and such other documents as such seller or such managing underwriters may reasonably request including in order to facilitate the disposition of the Registrable Securities owned by such seller, and upon
request, a copy of any and all transmittal letters or other correspondence to or received from, the SEC or any other Governmental Entity relating to such offer; 

(iv) use all reasonable efforts (x) to register or qualify such Registrable Securities under such other securities or blue
sky laws of such jurisdictions as the Investor reasonably requests, (y) to keep such registration or qualification in effect for so long as such Registration Statement remains in effect, and (z) to do any and all other acts and things
which may be reasonably necessary or advisable to enable the Investor to consummate the disposition in such jurisdictions of the Registrable Securities owned by it (provided that the Company shall not be required to (A) qualify generally
to do business in any jurisdiction where it would not otherwise be required to qualify but for this subsection, (B) subject itself to taxation in any such jurisdiction or (C) consent to general service of process in any such jurisdiction);

 (v) notify the Investor and its counsel and the managing underwriters: (x) at any time when a Prospectus relating to
the applicable Registration Statement is required to be delivered under the Securities Act, (A) upon discovery that, or upon the happening of any event as a result of which, such Registration Statement, or the Prospectus or Free Writing
Prospectus relating to such Registration Statement, or any document incorporated or deemed to be incorporated therein by reference contains an untrue statement of a material fact or omits any fact necessary to make the statements in the Registration
Statement or the Prospectus or Free Writing Prospectus relating thereto not misleading or otherwise requires the making of any changes in such Registration Statement, Prospectus, Free Writing Prospectus or document, and, at the request of the
Investor, the Company shall promptly prepare a supplement or amendment to such Prospectus or Free Writing Prospectus, furnish a reasonable number of copies of such supplement or amendment to the Investor, its counsel and the managing underwriters
and file such supplement or amendment with the SEC so that, as thereafter delivered to the purchasers of such Registrable Securities, such Prospectus or Free Writing Prospectus as so amended or supplemented shall not contain an untrue statement of a
material fact or omit to state any fact necessary to make the statements therein not misleading, (B) as soon as the Company becomes aware of any comments or inquiries by the SEC or any requests by the SEC or any Federal or state Governmental
Entity for amendments or supplements to a Registration Statement or related Prospectus or Free Writing Prospectus covering Registrable Securities or for additional information relating thereto, (C) as soon as the Company becomes aware of the
issuance or threatened issuance by the SEC of any stop order suspending or threatening to suspend the effectiveness of a Registration Statement covering the Registrable Securities or (D) of the receipt by the Company of any notification with
respect to the suspension of the qualification or exemption from qualification of any Registrable Security for sale in any jurisdiction, or the initiation or threatening of any proceeding for such purpose; (y) when each Registration Statement
or any amendment thereto has been filed with the SEC and when each Registration Statement or the related Prospectus or Free Writing Prospectus or any Prospectus supplement or any post-effective amendment thereto has become effective; and (z) if
at any time the Company has reason to believe that the representations and warranties of the Company contained in any agreement contemplated by Section 3(d)(viii) below relating to any applicable offering cease to be true
and correct; 

  
 7 













 (vi) use its reasonable best efforts to cause all such Registrable

disposition of such Registrable Securities (including effecting a stock split, a combination of shares, or other recapitalization) and provide reasonable cooperation, including causing appropriate officers to attend and participate in “road
shows” and analyst or investor presentations and such other selling or other informational meetings organized by the underwriters, if any, to the extent reasonably requested by the lead or managing underwriters, with all out-of-pocket costs and expenses incurred by the Company or such officers in connection with such attendance and participation to be paid by the Company; provided,
that, the foregoing requirement for the appropriate officers of the Company to attend and participate in “road shows” shall only be applicable in the event the event the applicable offering includes securities with a total offering

Prospectus supplements relating to a Shelf Takedown, if applicable; 
 (xi) in the event of the issuance or threatened
issuance of any stop order suspending the effectiveness of a Registration Statement, or of any order suspending or preventing the use of any related Prospectus or suspending the qualification of any security included in such Registration Statement
for sale in any jurisdiction, the Company shall use all reasonable efforts promptly to (x) prevent the issuance of any such stop order, and in the event of such issuance, to obtain the withdrawal of such order and (y) obtain the withdrawal
of any order suspending or preventing the use of any related Prospectus or Free Writing Prospectus or suspending qualification of any Registrable Securities included in such Registration Statement for sale in any jurisdiction at the earliest

or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or
(y) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any other federal law, any state or foreign securities law, or any rule or regulation promulgated under of the foregoing laws, relating to the offer
or sale of the Registrable Securities, and in any such case, the Company agrees to reimburse each such indemnified party, 

  
 10 













 
as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating, preparing or defending any such Loss, claim, damage, liability, action or investigation
(whether or not the indemnified party is a party to any proceeding); provided, however, that the Company will not be liable in any case to the extent that any such Loss arises out of or is based upon any such untrue statement or alleged
untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information relating to the Investor furnished to the Company by or on behalf of the Investor specifically for inclusion therein, including
any notice and questionnaire. This indemnity agreement will be in addition to any liability which the Company may otherwise have. 

(ii) Indemnification by the Investor. The Investor agrees to indemnify and hold harmless the Company and each of its
Affiliates, directors, employees, members, managers and agents and each Person who controls the Company within the meaning of either the Securities Act or the Exchange Act, to the fullest extent permitted by applicable Law, from and against any and
all Losses to which they or any of them may become subject insofar as such Losses arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in a Registration Statement as originally filed or in any
amendment thereof, or in the Disclosure Package or any Investor Free Writing Prospectus, preliminary, final or summary Prospectus included in any such Registration Statement, or in any amendment thereof or supplement thereto, or arise out of or are
based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, to the extent, but only to the extent, that any such untrue statement or alleged
untrue statement or omission or alleged omission is contained in any written information relating to the Investor furnished to the Company by or on behalf the Investor specifically for inclusion therein; provided, however, that the total
amount to be indemnified by the Investor pursuant to this Section 3(f)(ii) shall be limited to the net proceeds (after deducting underwriters’ discounts and commissions) received by the Investor in the offering to
which such Registration Statement or Prospectus relates; provided further that the Investor shall not be liable in any case to the extent that prior to the filing of any such Registration Statement or Disclosure Package, or any amendment
thereof or supplement thereto, it has furnished in writing to the Company, information expressly for use in, and within a reasonable period of time prior to the effectiveness of such Registration Statement or Disclosure Package, or any amendment
thereof or supplement thereto which corrected or made not misleading information previously provided to the Company. This indemnity agreement will be in addition to any liability which the Investor may otherwise have. 

(iii) Notification. If any Person shall be entitled to indemnification under this Section 3(f)
(each, an “Indemnified Party”), such Indemnified Party shall give prompt notice to the party required to provide indemnification (each, an “Indemnifying Party”) of any claim or of the commencement of
any proceeding as to which indemnity is sought. The Indemnifying Party shall have the right, exercisable by giving written notice to the Indemnified Party as promptly as reasonably practicable after the receipt of written notice from such
Indemnified Party of such claim or proceeding, to assume, at the Indemnifying Party’s expense, the defense of any such claim or litigation, with counsel reasonably satisfactory to the Indemnified Party and, after notice from the Indemnifying
Party to such Indemnified Party of its election to assume the defense thereof, the Indemnifying Party will not (so long as it shall continue to have the right to defend, contest, litigate and settle the matter in question in accordance with this
Section 3(f)(iii)) be liable to such Indemnified Party hereunder for any legal expenses and other expenses subsequently incurred by such Indemnified Party in connection with the defense thereof; provided, however,
that an Indemnified Party shall have the right to employ separate counsel in any such claim or litigation, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party unless the Indemnifying Party shall have failed
within a reasonable period of time to 

  
 11 













 
assume such defense and the Indemnified Party is or would reasonably be expected to be materially prejudiced by such delay. The failure of any Indemnified Party to give notice as provided herein
shall relieve an Indemnifying Party of its obligations under this Section 3(f) only to the extent that the failure to give such notice is materially prejudicial or harmful to such Indemnifying Party’s ability to defend
such action. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the prior written consent of each Indemnified Party (which consent shall not be unreasonably withheld or delayed), consent to entry of any
judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation. The indemnity
agreements contained in this Section 3(f) shall not apply to amounts paid in settlement of any claim, loss, damage, liability or action if such settlement is effected without the prior written consent of the Indemnifying
Party, which consent shall not be unreasonably withheld or delayed. The indemnification set forth in this Section 3(f) shall be in addition to any other indemnification rights or agreements that an Indemnified Party may
have. An Indemnifying Party who is not entitled to, or elects not to, assume the defense of a claim will not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such Indemnifying Party with respect to
such claim, unless in the reasonable judgment of any Indemnified Party a conflict of interest may exist between such Indemnified Party and any other Indemnified Parties with respect to such claim. 

(iv) Contribution. If the indemnification provided for in this Section 3(f) is held by a court
of competent jurisdiction to be unavailable to an Indemnified Party, other than pursuant to its terms, with respect to any Losses or action referred to therein, then, subject to the limitations contained in this
Section 3(f), the Indemnifying Party, in lieu of indemnifying such Indemnified Party hereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Losses or action in such
proportion as is appropriate to reflect the relative fault of the Indemnifying Party, on the one hand, and the Indemnified Party, on the other, in connection with the actions, statements or omissions that resulted in such Losses or action, as well
as any other relevant equitable considerations. The relative fault of the Indemnifying Party, on the one hand, and the Indemnified Party, on the other hand, shall be determined by reference to, among other things, whether any action in question,
including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, has been made (or omitted) by, or relates to information supplied by such Indemnifying Party or such Indemnified Party, and
the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent any such action, statement or omission. The Company and the Investor agree that it would not be just and equitable if contribution pursuant to
this Section 3(f)(iv) was determined solely upon pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding sentence of this
Section 3(f)(iv). Notwithstanding the foregoing, the amount the Investor will be obligated to contribute pursuant to this Section 3(f)(iv) will be limited to an amount equal to the net proceeds
received by the Investor in respect of the Registrable Securities sold pursuant to the registration statement which gives rise to such obligation to contribute. No Person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. 

(g) Rule 144. With a view to making available to the Investor the benefits of Rule 144 promulgated under the Securities Act, the Company
covenants that it will (x) make available information necessary to comply with Rule 144, if available with respect to resales of the Registrable Securities under the Securities Act, at all times, and (y) take such further action as the
Investor may reasonably request, all to the extent required from time to time to enable it to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by Rule 144


  
 12 













 
promulgated under the Securities Act (if available with respect to resales of the Registrable Securities), as such rule may be amended from time to time. Upon the reasonable request of the
Investor, the Company will deliver to it a written statement as to whether it has complied with such information requirements, and, if not, the specific reasons for non-compliance. 

(h) Suspension of Sales; Adverse Disclosure. Upon receipt of written notice from the Company that a Registration Statement or Prospectus
contains a Misstatement, the Investor shall forthwith discontinue disposition of Registrable Securities until it has received copies of a supplemented or amended Prospectus correcting the Misstatement (it being understood that the Company hereby
covenants to prepare and file such supplement or amendment as soon as practicable after the time of such notice), or until it is advised in writing by the Company that the use of the Prospectus may be resumed. If the filing, initial effectiveness or
continued use of a Registration Statement at any time would require the Company to make an Adverse Disclosure or would require the inclusion in such Registration Statement of financial statements that are unavailable to the Company for reasons
beyond the Company’s control, the Company may, upon giving prompt written notice of such action to the Investor, delay the filing or initial effectiveness of, or suspend use of, such Registration Statement for the shortest period of time, but
in no event more than 90 days, determined in good faith by the Company to be necessary for such purpose; provided that such right to delay or suspend shall be exercised by the Company not more than two times, which may be
consecutive, in any 12-month period. In the event the Company exercises its rights under the preceding sentence, the Investor agrees to suspend, immediately upon their receipt of the notice referred
to above, its use of the Prospectus relating to any sale or offer to sell Registrable Securities. The Company shall immediately notify the holders of Registrable Securities of the expiration of any period during which it exercised its rights under
this Section 3(h). 
 (i) Restrictions on Transfer. In connection with any underwritten offering of
equity securities of the Company, the Investor agrees that it shall not transfer any equity securities of the Company (other than those included in such offering pursuant to this Agreement), without the prior written consent of the Company, during
the seven days prior to and the 90-day period beginning on the date of pricing of such offering, except in the event the underwriter managing the offering otherwise agrees by written consent. The
Investor agrees to execute a customary lock-up agreement in favor of the underwriters of such offering to such effect. The Investor’s obligations under the second sentence of
this Section 3(i) shall only apply for so long as the Investor (together with its Affiliates) holds at least 5% of the issued and outstanding shares of Common Stock (calculated on as converted basis); provided
that (i) the Investor shall not be required to enter into any restriction on transfer under this Section 3(i) unless the Company’s officers, directors and other shareholders holding more than 5% of the Common Stock agree to
restrictions on transfer in connection with such offering that are at least as restrictive as those to be entered into by the Investor; and (ii) in the event that the underwriter of such offering releases any other party from such restrictions
on transfer prior to the expiration of such restrictions, any restrictions on transfer entered into by the Investor pursuant to this Section 3(i) shall automatically terminate. 

(j) In connection with any Shelf Takedown, the Company shall not effect any public sale or distribution of its Equity Securities, or any
securities convertible into or exchangeable or exercisable for such securities (except pursuant to registrations on Form S-8 or Form S-4 under the Securities Act), and
shall cause its officers and directors not to Transfer any Equity Securities, except in the event the underwriters managing the Shelf Takedown consent to such shorter period, during the seven days prior to and the
90-day period beginning on the date of pricing of such Shelf Takedown or such other period provided in the underwriting, placement or similar agreement executed in connection with such Shelf Takedown.

 Section 4. Preemptive Rights. 

(a) For the purposes of this Section 4, “Excluded Issuance” shall mean (i) the issuance of any Equity
Securities (including upon exercise of options) to directors, officers, employees, consultants or other agents of the Company as approved by the Board in connection with their employment or performance of services and pursuant to an employee stock
option plan, management incentive plan, restricted stock plan, stock purchase plan or stock, ownership plan or similar benefit plan, program or agreement as approved by the Board, (ii) the issuance of any Equity Securities in connection with
any “business combination” (as defined in the rules and regulations promulgated by the SEC) or otherwise in connection with bona fide acquisitions of securities or assets of another Person, business unit, division or business, in each
case, to the sellers in such transaction as consideration thereof, (iii) the issuance of any securities pursuant to the conversion, redemption or exchange of Preferred Stock issued to the Investor, (iv) the issuance of any shares of a
subsidiary of the Company to the Company or a wholly owned subsidiary of the Company, (v) the issuance of securities issued upon the conversion, exercise or exchange of options or convertible securities of the Company that were issued and
outstanding on the Effective Date, (vi) the issuance of securities by reason of a dividend, stock split or other distribution on shares of Common Stock, (vii) the issuance of Equity Securities into the public market pursuant to a bona
fide, broadly distributed underwritten public offering, and (viii) the issuance of bonds, debentures, notes or similar debt securities convertible into Common Stock not in excess of $250 million in the aggregate (when taken together with
all other such issuances). 
 (b) Until the Fall Away Date, if the Company proposes to offer or sell Equity Securities of any kind for cash,
other than in an Excluded Issuance, then the Company shall: 
 (i) give written notice to the Investor no less than fifteen
(15) Business Days prior to the closing of such issuance or, if the Company reasonably expects such issuance to be completed in less than fifteen (15) Business Days, such shorter period (which shall be as given as promptly as commercially
practicable but in any event not less than eight (8) Business Days prior to such closing), setting forth in reasonable detail (A) the designation and all of the material terms and provisions of the securities proposed to be issued (the
“Proposed Securities”), including, to the extent applicable, the voting powers, preferences and relative participating, optional or other special rights, and the qualifications, limitations or restrictions thereof and
interest rate and maturity, (B) the price and other terms of the proposed sale of such securities and (C) the amount of such securities proposed to be issued; provided that, following the delivery of such notice, the Company
shall deliver to the Investor any such information the Investor may reasonably request in order to evaluate the proposed issuance, except that, in connection with a public offering, the Company shall not be required to deliver any information that
has not been or will not be provided or otherwise made available to the proposed purchasers of the Proposed Securities; and 

(ii) offer to issue and sell to the Investor, on such terms as the Proposed Securities are issued and upon full payment by the
Investor, a portion of the Proposed Securities equal to a percentage determined by dividing: (x) the number of shares of Common Stock held or beneficially owned in the aggregate, on an as converted to Common Stock basis, by the Investor and its
Affiliates, by (y) the total number of shares of Common Stock outstanding immediately prior to the issuance of the Proposed Securities, on an as converted to Common Stock basis. 

(c) The Investor will have the option exercisable by written notice to the Company, to accept the Company’s offer and commit to purchase
any or all of the Equity Securities offered to be sold, which notice must be given on or prior to the Business Day immediately prior to the date of the closing of the issuance of such Equity Securities (or, if notice of all such terms has not been
given prior to the Business Day immediately prior to the such closing date, at any time prior to such closing date) (the failure of the Investor to respond within such time period shall be deemed a waiver of its rights under this Section
4 with respect to the applicable issuance of Equity Securities). Such notice to the Company shall constitute a binding commitment by the Investor to purchase the amount of Equity Securities so


  
 14 













 
specified at the price and other terms set forth in the Company’s notice to the Investor. The closing of the exercise of such subscription right shall take place simultaneously with the
closing of the sale of the Proposed Securities giving rise to such subscription right; provided, however, that the closing of any purchase by the Investor may be extended beyond the closing of the sale of the Proposed
Securities giving rise to such preemptive right to the extent necessary to obtain required approvals from any Governmental Entity. Upon the expiration of the offering period described above, the Company will be free to sell such Proposed Securities
that the Investor has not elected to purchase during the 90 days following such expiration on terms and conditions no more favorable to the purchasers thereof than those offered to the Investor in the notice delivered in accordance with this
Section 4. Any Proposed Securities offered or sold by the Company after such 90-day period must be reoffered to issue or sell to the Investor pursuant to this Section 4. 

(d) The election by the Investor not to exercise its subscription rights under this Section 4 in any one instance shall not affect
its right as to any subsequent proposed issuance. 
 (e) If the proposed issuance by the Company of securities which gave rise to the
exercise by the Investor of its preemptive rights pursuant to this Section 4 shall be terminated or abandoned by the Company without the issuance of any securities, then the purchase rights of the Investor pursuant to this
Section 4 shall also terminate as to such proposed issuance by the Company (but not any subsequent or future issuance), and any funds in respect thereof paid to the Company by the Investor in respect thereof shall be
refunded in full. 
 Section 5. Transfer Restrictions. 

(a) In addition to the other limitations set forth in this Section 5, the Investor may not at any time, other than in
an open market transaction, Transfer any Preferred Stock or any securities into which Preferred Stock is convertible into, redeemable for or exchangeable, including Common Stock, whether now owned or hereinafter acquired, owned directly by the
Investor or its subsidiaries or with respect to which the Investor or its subsidiaries has beneficial ownership within the rules and regulations of the SEC (collectively, the “Restricted Shares”), to (i) any Competitor
or Activist or (ii) any Person that would, to the Investor’s knowledge, hold 7.5% or more of the Common Stock (on an as converted basis) after giving effect to such Transfer. The Investor will provide written notice to the Company no less
than thirty days prior to the effectiveness of the first Transfer of Restricted Shares to a Person that is not an Affiliate of the Investor. 

(b) During the period commencing on the Effective Date and continuing until the calendar date that is eighteen (18) months following the
Effective Date (the “Lockup Date”), unless the Company otherwise provides prior written consent or pursuant to a Transfer permitted by Section 5(d), the Investor shall not Transfer any Restricted
Shares. 
 (c) During the period commencing on the Lockup Date and continuing until the calendar date that is two years following the
Effective Date, unless the Company otherwise provides prior written consent or pursuant to a Transfer permitted by Section 5(d), the Investor may only Transfer Restricted Shares in the event that at the time of such
Transfer the VWAP per share of Common Stock is equal to or greater than $24 per share of Common Stock (subject to appropriate adjustment in the event of a stock split, stock dividend, combination or other similar recapitalization) or less than or
equal to $8 per share of Common Stock (subject to appropriate adjustment in the event of a stock split, stock dividend, combination or other similar recapitalization). 

(d) Notwithstanding anything herein to the contrary, (i) the Investor may at any time Transfer the Restricted Shares (A) to any
Affiliate of the Investor, provided that such transferee agrees to be bound by the terms and restrictions set forth in this Agreement; (B) to give effect to any Acquisition 

  
 15 













 
Transaction or other acquisition, sale or merger involving a majority of the assets, properties or Equity Securities of the Company and its subsidiaries that has been recommended or approved by a
majority of the Board; or (C) subject to the restrictions set forth in Section 5(a), solely to the extent necessary so that the Investor Ownership Percentage does not equal or exceed 10%, including to the Company in
connection with a repurchase of any Equity Securities of the Company, including pursuant to a tender offer, exchange offer or other offer or proposal, including in connection with the sale of any Put Shares; and (ii) Section 5(b)
and Section 5(c) shall automatically terminate and be of no further force and effect in upon the occurrence of an Insolvency Event (as defined in the Framework Agreement) or upon the expiration or termination of the
Framework Agreement; provided that, if the Framework Agreement is terminated by Avaya, Inc. pursuant to Section 11.2(b)(ii)(A), then Section 5(b) and Section 5(c) shall automatically
terminate and be of no further force and effect solely with respect to securities into which Preferred Stock is convertible into, redeemable for or exchangeable, including Common Stock (and not with respect to Preferred Stock). 

Section 6. Standstill. 
 (a) From the
Effective Date until such time as both (i) the Investor Ownership Threshold is no longer satisfied and (ii) there is no longer an Investor Director serving as a member of the Board (the “Standstill Period”), the Investor
shall not, and shall cause its subsidiaries and Representatives acting on its and its respective subsidiaries’ behalf not to, directly or indirectly (including through any arrangements with a third party): 

(i) except for Equity Securities of the Company received by way of stock splits, stock dividends, reclassifications,
recapitalizations or other distributions by the Company in respect of its Common Stock, and Equity Securities purchased pursuant to Section 4 or acquired as a result of any conversion of Preferred Stock or the exercise of
any rights under the Framework Agreement, (x) acquire, agree to acquire, propose or offer to acquire (including through the acquisition of Beneficial Ownership) (directly or indirectly, by purchase or otherwise) any Equity Securities of the
Company; provided that this clause (i) shall not prohibit acquisitions of Common Stock, if after giving effect to such transaction, the Investor Ownership Threshold is equal to or less than 10%, or (y) authorize or make a tender
offer, exchange offer or other offer or proposal, whether oral or written, to acquire (directly or indirectly, by purchase or otherwise) any Equity Securities of the Company;(ii) make, or in any way participate, directly or indirectly, in any
“solicitation” of “proxies,” “consents” or “authorizations” to vote (as such terms are used in the rules of the SEC), or seek to advise or influence any Person with respect to the voting of any shares of
Voting Stock (other than in each case (x) the Investor and its Affiliates, (y) in accordance with and consistent with the recommendation of the Board or (z) with respect to the election of a Nominee); 

(iii) form, join or in any way participate in a “group” as defined in Section 13(d)(3) of the Exchange Act, for
the purpose of voting, acquiring, holding, or disposing of, any Voting Stock; 
 (iv) submit to the Board a proposal for or
offer of, with or without conditions, any acquisition of, or merger, recapitalization, reorganization, business combination or other extraordinary transaction involving, the Company or any subsidiary thereof or any of its or their respective

announcement with respect thereto; 

  
 16 













 (v) request the Company or any of its subsidiaries directly or indirectly,

the Board or otherwise seek representation on the Board (except as expressly set forth in this Agreement) or seek the removal of any member of the Board (except for the Investor Director); or 

(ix) take any action that would reasonably be expected to require the Company to make a public announcement regarding the
possibility of a transaction or any other matter described in this Section 6. 
 (b) Nothing in this Agreement,
including this Section 6, shall prohibit or restrict (i) the voting (as a director) or other actions taken by the Investor Director in his or her capacity as a member of the Board in a manner consistent with his or her
fiduciary duties as a member of the Board, or (ii) Investor or any of its subsidiaries or Representatives from exercising any of its, his, or her rights or remedies under or in connection with any Contract with the Company or any of its
Affiliates, including the Framework Agreement. 
 (c) Notwithstanding the foregoing, if at any time (i) the Company enters into a
definitive agreement with a third party providing for an Acquisition Transaction, or (ii) a tender or exchange offer for all or a majority of each class of the Company’s outstanding Equity Securities is commenced by any Person and within
ten (10) Business Days thereafter, the Board has not publicly taken a position rejecting such tender or exchange offer and recommending that the stockholders of the Company not tender any Equity Securities of the Company into such tender or
exchange offer, the Investor and its Affiliates shall be permitted to make and pursue (publicly or otherwise) a competing proposal with respect to such Acquisition Transaction and take any actions otherwise prohibited by this
Section 6 in furtherance thereof. 
 Section 7. Right of First Refusal; Put Right. 

(a) Right of First Refusal. 

(i) If after the Lockup Date and subject to the other terms set forth herein, the Investor or any of its subsidiaries desires
to Transfer more than 100,000 shares of Common Stock in any single transaction or series of related transactions (in each case, other than pursuant to an open market transaction), then the Investor shall provide the Company prior written notice of
such Transfer at least 10 Business Days prior to the effectiveness of such proposed Transfer (the “ROFR Offer Notice”), specifying in reasonable detail the identity of the prospective transferee(s), the number of shares of Common
Stock to be Transferred (the “Offered Shares”) and the price and other terms and conditions of the proposed Transfer. 

  
 17 













 (ii) The Company may elect to purchase all or a portion of the Offered

on the date immediately prior to the proposed trade date less a 0.5% discount on such price, by delivering written notice of such election to the Investor within 5 Business Days after receipt by the Company of the ROFR Offer Notice. 

(iii) If the Company elects to purchase any of the Offered Shares from the Investor, such purchase shall be consummated as soon
as practicable after the delivery of the election notice by the Company to the Investor, but in any event within 5 Business Days of the delivery of such notice. 

(b) Put Right. 

(i) If at any time the Company proposes to repurchase any Equity Securities of the Company, including pursuant to a tender
offer, exchange offer or other offer or proposal that would cause the Investor Ownership Percentage to be equal to or exceed 10% (after giving effect to such repurchase, tender offer, exchange offer, or other offer, proposal or action) (a
“Put Right Trigger”), then the Company shall provide Investor prior written notice of such Put Right Trigger at least 10 Business Days prior to the consummation of such Put Right Trigger (the “Put Right Trigger
Notice”), specifying in reasonable detail the scope of such Put Right Trigger, including the price and other terms and conditions of such Put Right Trigger.

Trigger (a “Put Right Exercise Notice”), and, upon delivery thereof, the Company shall be obligated to purchase from Investor or its Affiliates, as applicable, the Put Shares at a price per share equal to (i) if the Put Shares
are Preferred Stock, the greater of (x) the Liquidation Preference (as defined in the Certificate of Designations) of such shares of Preferred Stock and (y) the aggregate amount that would be payable in connection with such Put Right
Trigger in respect of all shares of Common Stock issuable upon conversion of such share of Preferred Stock, and (ii) if the Put Shares are Common Stock, the per share price payable in respect of a share of Common Stock in connection with such

in accordance with generally accepted accounting principles in the United States, as in effect on the date thereof; provided that in connection with a repurchase of Equity Securities by the Company, Investor shall be required to either participate
in such repurchase in order to not exceed the forgoing threshold or waive the restriction set forth in this Section 9(b)(i);

hereof); and 
 (iii) make any Restricted Payments (as defined in the Company Term Loan Credit Agreement as in effect as of
the date hereof) if, immediately after giving effect to such Restricted Payment, Avaya Inc. would be unable to make a cash distribution to Company in an aggregate amount sufficient to satisfy Company’s payment obligations in connection with any
Redemption. 
 Section 10. Definitions. 

“Activist” means, as of any date of determination, a Person (other than the Investor and its Affiliates) that has,
