Each party shall execute and deliver both before and after the Closing such further certificates, agreements and other documents and take such other actions as the other parties may reasonably request to consummate or implement such transactions or to evidence such events or matters. Each party hereto agrees to keep the other party apprised of the status of matters referred to in this Section 3.1.

Following the Requisite Stockholder Approval and prior to the effectiveness of the conversion of Series A-2 Preferred Stock into Series A-1 Preferred Stock, the Company shall apply and cause to be approved for listing on the NASDAQ Global Select Market the shares of Class A Common

Stock that could potentially be issued upon conversion of the Series A-1 Preferred Stock into which the Series A-2 Preferred Stock will be converted (including any shares of Class A Common Stock or Series A-1 Preferred Stock that could potentially be issued as dividends (whether directly or as an increase to “Stated Value”)), subject to official notice of issuance.

(g) At all times while an Investor Director or Investor Observer is serving as a member or observer of the Board of Directors, and following any such Investor Director’s or Investor Observer’s death, disability, resignation or removal, such Investor Director or Investor Observer shall be entitled to all rights to indemnification and exculpation as are then made available to any other member or observer of the Board of Directors.

(i) The right to designate directors pursuant to Section 4.4(b) shall automatically terminate at such time as the Approved Holders no longer Beneficially Own a sufficient number of shares required to designate an Investor Director set forth in Section 4.4(b)(2), and at such time, if requested in writing by the Company, any Investor Directors or Investor Observer then serving on the Board of Directors in excess of the entitled amount (if less than all then Investor Directors or Investor Observers, then as selected by the Approved Holder Majority) shall promptly resign from the Board of Directors.

(j) Nothing in this Section 4.4 shall be deemed to require that any party hereto, or any Affiliate thereof, act or be in violation of any applicable provision of law, regulation, legal duty or requirement or stock exchange or stock market rule.

(l) To the fullest extent permitted by applicable law, the Company, on behalf of itself and its subsidiaries, renounces any interest or expectancy of the Company and its subsidiaries in, or in being offered an opportunity to participate in, any business opportunities that are from time to time presented to the Investors or any of their respective affiliates or any of their respective agents, shareholders, members, partners, directors, officers, employees, affiliates or subsidiaries (other than the Company and its subsidiaries), including any director or officer of the Company who is also an agent, shareholder, member, partner, director, officer, employee, affiliate or subsidiary of any Investor (each, a “Specified Party”), even if the business opportunity is one that the Company or its subsidiaries might reasonably be deemed to have pursued or had the ability or desire to pursue if granted the opportunity to do so, and no Specified Party shall have any duty to communicate or offer any such business opportunity to the Company or be liable to the Company or any of its subsidiaries or any stockholder, including for breach of any fiduciary or other duty, as a director or officer or controlling stockholder or otherwise, and the Company shall indemnify each Specified Party against any claim that such person is liable to the Company or its stockholders for breach of any fiduciary duty, by reason of the fact that such person (i) participates in, pursues or acquires any such business opportunity, (ii) directs any such business opportunity to another person or (iii) fails to present any such business opportunity, or information regarding any such business opportunity, to the Company or its subsidiaries, unless, in the case of a person who is a director or officer of the Company, such business opportunity is expressly offered to such director or officer in writing solely in his capacity as a director or officer of the Company.

No Investor Indemnified Party shall be entitled to recover special, consequential (including lost profits) or punitive damages, provided that any losses recovered by a third party against Investor Indemnified Parties as a result of, arising out of, or in any way related to the breach of any of the representations, warranties or covenants of the Company contained herein shall be included in such Investor Indemnified Party’s losses, regardless of the form of such third party’s losses and whether components of such awards relate to special, consequential or punitive damages.

Section 5.3 Indemnification Procedure. Promptly after any Investor Indemnified Party or Company Indemnified Party, as applicable (the “Indemnified Party”), has received notice of any indemnifiable claim hereunder, or the commencement of any action, suit or proceeding by a third Person, which such Indemnified Party believes in good faith is an indemnifiable claim under this Agreement, such Indemnified Party shall give the indemnitor hereunder (the “Indemnifying Party”) written notice of such claim or the commencement of such action, suit or proceeding, but failure to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure. Such notice shall state the nature and the basis of such claim to the extent then known. The Indemnifying Party shall have the right to defend and settle, at its own expense and by its own counsel who shall be reasonably acceptable to the Indemnified Party, any such matter as long as the Indemnifying Party pursues the same diligently and in good faith and makes an unqualified acknowledgment in writing of its obligation to provide indemnification to the Indemnified Party with respect to such matter. If the Indemnifying Party undertakes to defend or settle, it shall promptly notify the Indemnified Party of its intention to do so, and the Indemnified Party shall cooperate with the Indemnifying Party and its counsel in all commercially reasonable respects in the defense thereof and the settlement thereof. Such cooperation shall include furnishing the Indemnifying Party with any books, records and other information reasonably requested by the Indemnifying Party and in the Indemnified Party’s possession or control. Such cooperation of the Indemnified Party shall be at the cost of the Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted liability, and for so long as the Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement of such asserted liability; provided, however, that the Indemnified Party shall be entitled (a) at its expense, to participate in the defense of such asserted liability and the negotiations of the settlement thereof and (b) if (i) the Indemnifying Party has failed to assume the defense or employ counsel reasonably acceptable to the Indemnified Party or (ii) if the defendants in any such action include both the Indemnified Party and the Indemnifying Party and counsel to the Indemnified Party shall have concluded that there may be reasonable defenses available to the Indemnified Party that are different from or in addition to those available to the Indemnifying Party or if the interests of the Indemnified Party reasonably may be deemed to conflict with the interests of the Indemnifying Party, then the Indemnified Party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the Indemnifying Party as incurred. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any indemnified claim without the consent of the Indemnified Party, unless the settlement thereof imposes no liability or obligation on, and includes a complete release from liability of, and does not include any admission of wrongdoing or malfeasance by, the Indemnified Party.

Section 6.3 Amendment; Waiver. No amendment or waiver of any provision of this Agreement will be effective with respect to any party unless made in writing and signed by an officer of a duly authorized representative of such party. No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The conditions to each party’s obligation to consummate the Closing are for the sole benefit of such party and may be waived by such party in whole or in part to the extent permitted by applicable law. No waiver of any party to this Agreement, as the case may be, will be effective unless it is in a writing signed by a duly authorized officer of the waiving party that makes express reference to the provision or provisions subject to such waiver.

For so long as any shares of Series A-1 Preferred Stock are outstanding, no cash dividend may be declared or paid on the Common Stock, and no other distributions may be made to holders of Common Stock, during a Dividend Period unless a cash dividend or such distribution, if applicable, is also declared and paid on the Series A-1 Preferred Stock to Holders for such dividend in the same form and in an amount per share of Series A-1 Preferred Stock equal to the product of (i) the per share dividend or distribution declared and paid in respect of each share of Class A Common Stock and (ii) the number of shares of Class A Common Stock into which such share of Series A-1 Preferred Stock is then convertible on the Record Date for such dividend or distribution.

(iii) If the Optional Conversion Date, Automatic Conversion Date or Mandatory Conversion Date with respect to any share of Series A-1 Preferred Stock is prior to the Record Date for any dividend, the Holder of such shares will not be entitled to any such dividend, subject to any Unpaid Dividends being taken into account in Section 7. If the Optional Conversion Date, Automatic Conversion Date or Mandatory Conversion Date with respect to any share of Series A-1 Preferred Stock is after the

Record Date for any dividend but before the corresponding Dividend Payment Date, the Holder of such share of Series A-1 Preferred Stock shall have the right to receive such dividend, notwithstanding the conversion of such shares prior to the Dividend Payment Date.

(i) Notwithstanding anything to the contrary in Section 4(c), for no more than 12 Dividend Periods (whether consecutive or non-consecutive) prior to [●], 2024 (a “PIK Quarter”), the Company may, at its option and in its sole discretion as exercised by the Board of Directors, with respect to all or any portion of the accrued, declared and payable dividends for such Dividend Period, elect to (A) pay such dividends in the form of additional shares of Series A-1 Preferred Stock at a per share price equal to $975.00 or, (B) in lieu of paying such dividends, increase the Stated Value of the applicable shares of Series A-1 Preferred Stock by an amount equal to the accrued and payable dividends on such shares for such applicable PIK Quarter. If the Company fails to fully declare and pay in cash by the Dividend Payment Date, or is unable to fully pay in cash by such date, the accrued dividends with respect to a Dividend Period then, with respect to any unpaid portion but subject to Section 4(e), (x) to the extent any of the 12 PIK Quarters remain available, the Company shall be deemed to have made an election under Section 4(d)(i)(B) and (y) to the extent none of the 12 PIK Quarters remain available, the Stated Value shall be automatically increased by an amount equal to the lesser of (i) a Dividend Rate of 9.0% per annum and (ii) the unpaid portion of any such accrued dividends (provided that any amounts which increase the Stated Value hereby shall no longer be considered Unpaid Dividends), with any remaining unpaid portion in excess of such increase in Stated Value remaining Unpaid Dividends.

(ii) For the avoidance of doubt, any portion of a declared dividend not paid as provided in the foregoing clauses will be paid in cash.

(i) Except as permitted by Section 4(d)(i), and unless the Dividend Rate is already adjusted pursuant to Section 4(e)(ii), if, at any time, the Company fails to fully declare and pay all accrued dividends in cash on a Dividend Payment Date, then the Dividend Rate on the Series A-1 Preferred Stock shall automatically increase by (A) 5.0% per annum effective as of the first day of the applicable Dividend Period and (B) an additional 1.0% for each successive Dividend Period in which the Company so fails to fully declare and pay, up to the maximum Dividend Rate of 20.0% per annum,. Dividends on the Series A-1 Preferred Stock shall accrue at the increased Dividend Rate for so long until the Company shall have paid dividends at such increased Dividend Rate fully in cash in accordance with Section 4(c) for two consecutive Dividend Periods, upon which time the Dividend Rate on Series A-1 Preferred Stock shall automatically decrease and revert to 9.0% per annum to the extent dividends continue to be paid fully in cash.

(ii) If, on [●], 2024, the Prevailing Market Price per share of the Common Stock, is less than the Conversion Price then in effect, or the terms of the automatic

conversion in Section 7(c) are not satisfied, then the Dividend Rate shall automatically increase to 20.0% per annum as of such date, payable only in cash; provided, however, that, the Company, at its option and in its sole discretion (but only exercisable on such date in lieu of the Dividend Rate increase), may, by notice to the Holders, instead elect to exchange each share of outstanding Series A-1 Preferred Stock for senior unsecured obligations of the Company (the “Notes”) on such date (the “Note Conversion Date”) as follows:

(f) Each dividend will be payable to Holders of record as they appear in the records of the Company on the applicable Record Date, which shall be on the fifteenth (15th) day of the month in which the relevant Dividend Payment Date occurs.

(a) In the event of any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company, Holders shall be entitled to receive out of the assets of the Company or proceeds thereof legally available for distribution to stockholders of the Company, after satisfaction of all liabilities, if any, to creditors of the Company and subject to Section 5(b) and to the rights of holders of any shares of capital stock of the Company then outstanding ranking senior to the Series A-1 Preferred Stock in respect of distributions upon liquidation, dissolution or winding up of the Company, and before any distribution of such assets or proceeds is made to or set aside for the holders of Common Stock and any other Junior Securities, a liquidating distribution in an amount equal to the greater of (i) the Stated Value plus, without duplication, Unpaid Dividends, per share and (ii) the amount of the liquidating distributions, as determined by the Board of Directors (or the trustee or other Person or Persons administering the liquidation, dissolution or winding-up of the Company in accordance with applicable law), that would be made on the number of shares of Class A Common Stock into which such shares of Series A-1 Preferred Stock are convertible immediately before such liquidation, dissolution or winding-up of the Company. After payment of the full amount of such liquidation distribution, the Holders shall not be entitled to any further participation in any distribution of assets by the Company.

(b) In the event the assets of the Company available for distribution to stockholders upon any liquidation, dissolution or winding-up of the affairs of the Company,

whether voluntary or involuntary, shall be insufficient to pay in full the amounts payable with respect to all outstanding shares of the Series A-1 Preferred Stock and the corresponding amounts payable on any Parity Securities, Holders and the holders of such Parity Securities shall share ratably in any distribution of assets of the Company in proportion to the full respective liquidating distributions to which they would otherwise be respectively entitled.

(c) The Company’s consolidation or merger with or into any other entity, the consolidation or merger of any other entity with or into the Company, or the sale of all or substantially all of the Company’s property or business or other assets will not constitute its liquidation, dissolution or winding up, but instead shall be subject to Section 17.

In order to convert shares of Series A-1 Preferred Stock into shares of Class A Common Stock pursuant to this Section 7(a), the Holder must surrender the certificates representing such shares of Series A-1 Preferred Stock (or, if such certificate or certificates have been lost, stolen, or destroyed, a lost certificate affidavit and indemnity in form and substance reasonably acceptable to the Company), accompanied by transfer instruments reasonably satisfactory to the Company, to the principal office of the Company (or such other place mutually acceptable to the Holder and the Company), together with written notice that such Holder elects to convert all or such number of shares represented by such certificates as specified therein. With respect to a conversion pursuant to this Section 7(a), the date of receipt of such certificates, together with such notice by the Company or (in accordance with the immediately preceding sentence) its authorized agent will be the date of conversion (the “Optional Conversion Date”).

(b) Mandatory Conversion. Subject to the conditions in this Section 7(b), the Company shall have the right, at its option and in its sole discretion, at any time or from time to

time, to cause some or all shares of Series A-1 Preferred Stock to be converted, in minimum increments of 5,000 shares and even multiples thereof (or, if the aggregate amount of shares of Series A-1 Preferred Stock held by any Holder is less than 5,000 shares, then all of the shares held by such Holder), into (i) that number of duly authorized, validly issued, fully paid and nonassessable shares of Class A Common Stock equal to the Conversion Rate in effect as of the Mandatory Conversion Date plus (ii) cash in lieu of fractional shares, as set forth in Section 12(b). Any Unpaid Dividends on such shares of Series A-1 Preferred Stock as of such Optional Conversion Date will be paid (A) in cash or, (B) at the option and in the sole discretion of the Company, in the form of additional shares of duly authorized, validly issued, fully paid and nonassessable shares of Class A Common Stock at the Conversion Price then in effect; provided that such issuance of additional shares of Class A Common Stock would not result in a violation by the Company of any applicable NASDAQ Listing Rules. The right to mandatorily convert the Series A-1 Preferred Stock pursuant to this Section 7(b) is subject to the following conditions:

(i) the Common Stock VWAP shall have exceeded 200% of the Conversion Price for 20 Trading Days (whether or not consecutive) during any 30 consecutive Trading Day period, if such mandatory conversion occurs on or prior to [●], 2019;

(ii) the Common Stock VWAP shall have exceeded 175% of the Conversion Price for 20 Trading Days (whether or not consecutive) during any 30 consecutive Trading Day period, if such mandatory conversion occurs on or after [●], 2019 but prior to [●], 2020;

(iii) the Common Stock VWAP shall have exceeded 150% of the Conversion Price for 20 Trading Days (whether or not consecutive) during any 30 consecutive Trading Day period, if such mandatory conversion occurs after [●], 2020; and

If the Company elects to cause less than all the shares of the Series A-1 Preferred Stock to be converted, the Company shall select the Series A-1 Preferred Stock to be converted from each Holder on a pro rata basis unless agreed upon otherwise by the Holders. If the Company selects a portion of a Holder’s Series A-1 Preferred Stock for partial conversion and such Holder converts a portion of its shares of Series A-1 Preferred Stock, both converted portions will be deemed to be from the portion selected for conversion at the option and in the sole discretion of the Company under this Section 7.

(c) Automatic Conversion. If on [●], 2024, the Prevailing Market Price per share of the Common Stock, is equal to or greater than the Conversion Price then in effect, and the Equity Conditions are satisfied, then each share of Series A-1 Preferred Stock shall automatically convert into (i) that number of duly authorized, validly issued, fully paid and nonassessable shares of Class A Common Stock equal to the Conversion Rate then in effect on such date (the “Automatic Conversion Date”) plus (ii) cash in lieu of fractional shares, as set forth in Section 12(b). Any Unpaid Dividends on such shares of Series A-1 Preferred Stock as of such Automatic Conversion Date will be paid (A) in cash or, (B) at the option and in the sole discretion of the Company, in the form of additional shares of duly authorized, validly issued, fully paid and nonassessable shares of Class A Common Stock at the Conversion Price then in effect; provided that such issuance of additional shares of Class A Common Stock would not result in a violation by the Company of any applicable NASDAQ Listing Rules.

(b) From and after the Optional Conversion Date, the Mandatory Conversion Date, the Automatic Conversion Date or Note Conversion Date, as applicable, the shares of Series A-1 Preferred Stock to be converted on such Optional Conversion Date, the Mandatory Conversion Date, the Automatic Conversion Date or Note Conversion Date, as applicable, will cease to be entitled to any dividends that may thereafter be declared on such Series A-1 Preferred Stock; such shares of Series A-1 Preferred Stock will no longer be deemed to be outstanding for any purpose; and all rights (except the right to receive from the Company the Class A Common Stock (and cash in lieu of fractional shares, if applicable) upon conversion thereof and any dividends previously declared or otherwise accrued on the Series A-1 Preferred Stock but not paid) of the Holder of such shares of Series A-1 Preferred Stock to be converted shall cease and terminate with respect to such shares. Prior to the Optional Conversion Date, the Automatic Conversion Date or the Mandatory Conversion Date, as applicable, except as otherwise provided herein, Holders shall have no rights as owners of the Class A Common Stock (or other relevant capital stock or equity interest into which the Series A-1 Preferred Stock may then be convertible in accordance herewith) (including voting powers, and rights to receive any dividends or other distributions on the Class A Common Stock or other securities issuable upon conversion) by virtue of holding shares of Series A-1 Preferred Stock.

(c) Shares of Series A-1 Preferred Stock duly converted in accordance with this Series A-1 Certificate of Designations, or otherwise reacquired by the Company.

(d) The Person or Persons entitled to receive the Class A Common Stock and/or cash issuable upon conversion of Series A-1 Preferred Stock shall be treated for all purposes as the record holder(s) of such shares of Class A Common Stock and/or securities as of the Close of Business on the Optional Conversion Date, the Automatic Conversion Date or the Mandatory Conversion Date, as applicable, with respect thereto. In the event that a Holder shall not by written notice designate the name in which shares of Class A Common Stock and/or cash to be issued or paid upon conversion of shares of Series A-1 Preferred Stock should be registered or paid or the manner in which such shares should be delivered, the Company shall be entitled to register and deliver such shares, and make such payment, in the name of the Holder and in the manner shown on the records of the Company.

(e) In the event that fewer than all of the shares of Series A-1 Preferred Stock held by any Holder who have requested to have a certificate representing its shares of Series A-1 Preferred Stock are converted pursuant to Section 7, then a new certificate representing the unconverted shares of Series A-1 Preferred Stock shall be issued to such Holder concurrently with the issuance of book-entry shares representing the applicable Class A Common Stock.

(a) The Conversion Price shall be subject to adjustment from time to time (successively and for each event described) in accordance with this Section 9. The term “Common Stock Outstanding” at any given time shall mean the aggregate number of shares of Class A Common Stock and Class B Common Stock issued and outstanding at such time.

(b) If the Company, at any time or from time to time while any of the Series A-1 Preferred Stock is outstanding, shall (i) subdivide the then outstanding shares of Common Stock into a greater number of shares of Class A Common Stock, or (ii) combine the then outstanding shares of Common Stock into a smaller number of shares of Common Stock (other than a dividend, distribution, subdivision or combination in connection with a transaction to which Section 5 applies), then the Conversion Price in effect at the Close of Business on the Record Date for such dividend or distribution, or immediately preceding the effective time and date of such subdivision or combination shall be adjusted, effective at such time, so that the Holder of each share of the Series A-1 Preferred Stock thereafter surrendered for conversion shall be entitled to receive the number and kind of shares of Common Stock that such holder would have owned or been entitled to receive immediately following such action had such shares of Series A-1 Preferred Stock been converted immediately prior to such time.

(c) In the case that a Tender Offer made by the Company or any Subsidiary of the Company for all or any portion of the Common Stock shall expire and such Tender Offer (as amended through the expiration thereof) shall require the payment to holders of the Class A Common Stock (based on the acceptance (up to any maximum specified in the terms of the

tender or exchange offer) of Purchased Shares) of aggregate consideration having a fair market value (as determined in good faith by the Board of Directors) per share of Common Stock that exceeds the Closing Price of the Common Stock on the last date on which tenders may be made pursuant to such Tender Offer (as amended through the expiration thereof) (the “Expiration Date”) or, if such date is not a Trading Day, the immediately preceding Trading Day, then, immediately prior to the opening of business on the day after the Expiration Date, the Conversion Price shall be reduced by multiplying the Conversion Price as of immediately prior to the Close of Business on the Expiration Date by a fraction (i) the numerator of which shall be equal to the product of (A) the Prevailing Market Price on the Expiration Date and (B) the number of shares of Common Stock Outstanding (including any tendered shares) on the Expiration Date, and (ii) the denominator of which shall be equal to (A) the product of (x) the Prevailing Market Price on the Expiration Date and (y) the number of shares of Common Stock Outstanding (including any tendered shares) on the Expiration Date less the number of all shares validly tendered, not withdrawn and accepted for payment on the Expiration Date (such validly tendered shares, up to any such maximum, being referred to as the “Purchased Shares”) plus (B) the amount of cash plus the fair market value (as determined in good faith by the Board of Directors) of the aggregate consideration payable to stockholders of the Company pursuant to the Tender Offer (assuming the acceptance, up to any maximum specified in the terms of the tender or exchange offer, of Purchased Shares).

(d) Whenever the Conversion Price is to be adjusted in accordance with Section 9(b), the Company shall (i) compute the Conversion Price in accordance with Section 9(b) in good faith; (ii) as soon as practicable following the occurrence of an event that requires an adjustment to the Conversion Price pursuant to Section 9(b) (or if the Company is not aware of such occurrence, as soon as practicable after becoming so aware), provide, or cause to be provided, a written notice to the Holders of the occurrence of such event; and (iii) as soon as practicable following the determination of the revised Conversion Price in accordance with Section 9(b) hereof, provide, or cause to be provided, a written notice to the Holders setting forth in reasonable detail the method by which the adjustment to the Conversion Price was determined and setting forth the revised Conversion Price.

(e) Rights Plans. If the Company has a rights plan in effect with respect to the Common Stock on the Optional Conversion Date, the Mandatory Conversion Date or the Automatic Conversion Date, upon conversion of any shares of the Series A-1 Preferred Stock, Holders of such shares will receive, in addition to the shares of Class A Common Stock, the rights under the rights plan relating to such Common Stock, unless, prior to such Optional Conversion Date, Mandatory Conversion Date or Automatic Conversion Date, as applicable, the rights have (i) become exercisable or (ii) separated from the shares of Common Stock.

(a) After [●], 2020, the Company may, at its option and in its sole discretion, redeem shares of Series A-1 Preferred Stock, in minimum increments of 5,000 shares and even multiples thereof (or such lesser amount in the event that fewer than 5,000 shares remain outstanding), for cash as follows:

(i) prior to [●], 2021, in an amount equal to 110% of the Stated Value plus, without duplication, any Unpaid Dividends;

(b) The Company shall provide written notice (the “Redemption Notice”) to the Holders at least 30 calendar days prior to any optional redemption in accordance with Section 10(a); provided that nothing in the Redemption Notice shall prohibit the Holders from converting Series A-1 Preferred Stock into Common Stock prior to the Company’s proposed redemption date. If the Company elects to redeem fewer than all of the outstanding shares of Preferred Stock pursuant to this Section 10, the Series A-1 Preferred Stock will be redeemed on a pro rata basis across all Holders based on their respective ownership of Series A-1 Preferred Stock unless agreed upon otherwise by the Holders. The shares of Series A-1 Preferred Stock Preferred Stock not redeemed shall remain outstanding.

(c) If, after [●], 2024, the Company fails to fully declare and pay in cash by the Dividend Payment Date, or is unable to fully declare and pay in cash by such date, all accrued dividends with respect to a Dividend Period, the Company shall, automatically and immediately redeem in cash all of the Series A-1 Preferred Stock, in whole and not in part, plus without duplication, any Unpaid Dividends.

(d) Any shares of Series A-1 Preferred Stock that are redeemed or otherwise acquired by the Company shall be cancelled upon payment therefor and will resume the status of authorized and unissued shares of Preferred Stock, undesignated as to series, and will be available for future issuance, but shall not be reissued as shares of Series A-1 Preferred Stock. If only a portion of the shares of Series A-1 Preferred Stock represented by a certificate shall have been called for redemption, upon surrender of the certificate to the Company, the Company shall issue and deliver to the Holders a new certificate representing the number of shares of Series A-1 Preferred Stock represented by the surrendered certificate that have not been called for redemption.

(a) The Holders shall be entitled to (i) vote with the holders of the Class A Common Stock on all matters submitted for a vote of holders of Class A Common Stock, (ii) when voting with the Class A Common Stock, a number of votes equal to the number of shares of Class A Common Stock such Holder would hold on an “as-converted basis” on the Record Date for the determination of the holders of Class A Common Stock entitled to vote on the matter in question and (iii) notice of all stockholders’ meetings in accordance with the Certificate of Incorporation and Bylaws of the Company, and applicable law or regulation or stock exchange rule, as if the Holders of Series A-1 Preferred Stock were holders of Class A Common Stock.

(b) Each Holder will have one vote per share on any matter on which Holders of Series A-1 Preferred Stock are entitled to vote separately as a class, whether at a meeting or by written consent.

(c) So long as any shares of Series A-1 Preferred Stock are outstanding, in addition to any other vote or consent of stockholders required by law or the Certificate of Incorporation, the affirmative vote or consent of Holders of at least a majority of the outstanding shares of Series A-1 Preferred Stock, voting together as a separate class, given in person or by proxy, either in writing without a meeting or by vote at any meeting called for the purpose, shall be necessary for effecting or validating any amendment, modification or alteration of, or supplement to, the Certificate of Incorporation or this Series A-1 Certificate of Designations that would materially and adversely affect the relative rights, preferences, privileges or voting powers of the Series A-1 Preferred Stock or any Holder.

(a) No fractional shares of Class A Common Stock will be issued as a result of any conversion of, or as a dividend on, shares of Series A-1 Preferred Stock.

(b) In lieu of any fractional share of Class A Common Stock otherwise issuable in respect of any conversion pursuant to Section 7 hereof or any dividends issued pursuant to Section 4(d) hereof, the Company shall pay (concurrently with the issuance of the shares of Class A Common Stock) an amount in cash (computed to the nearest cent) equal to the same fraction of the Closing Price of the Class A Common Stock determined as of the second Trading Day immediately preceding the Optional Conversion Date, the Mandatory Conversion Date, the Automatic Conversion Date or the Dividend Payment Date, as applicable.

(c) If more than one share of the Series A-1 Preferred Stock is surrendered for conversion at one time by or for the same Holder, the number of full shares of Class A Common Stock issuable upon conversion thereof shall be computed on the basis of the aggregate number of shares of the Series A-1 Preferred Stock so surrendered.

(a) The Company shall at all times reserve and keep available out of its authorized and unissued Class A Common Stock or shares of Class A Common Stock acquired by the Company and not retired, solely for issuance upon the conversion of shares of Series A-1 Preferred Stock as provided in this Series A-1 Certificate of Designations, such number of shares of Class A Common Stock as shall from time to time be issuable upon the conversion of all the shares of Series A-1 Preferred Stock then outstanding. The Company shall take all such corporate and other actions as from time to time may be necessary to ensure that all shares of Class A Common Stock issuable upon conversion of shares of Series A-1 Preferred Stock will, upon issue, be duly and validly authorized and issued, fully paid and nonassessable. For purposes of this Section 13, the number of shares of Class A Common Stock that shall be deliverable upon the conversion of all outstanding shares of Series A-1 Preferred Stock shall be computed as if at the time of computation all such outstanding shares were held by a single Holder.

(b) Notwithstanding the foregoing, the Company shall be entitled to deliver upon conversion of shares of Series A-1 Preferred Stock, as herein provided, shares of Class A

Common Stock acquired and not retired by the Company (in lieu of the issuance of authorized and unissued shares of Class A Common Stock), so long as any such acquired shares are free and clear of all liens, charges, security interests or encumbrances (other than liens, charges, security interests and other encumbrances created by the Holders).

(c) All shares of Class A Common Stock delivered upon conversion of the Series A-1 Preferred Stock or paid as a dividend pursuant to Section 7(c) shall be duly authorized, validly issued, fully paid and non-assessable, free and clear of all liens, claims, security interests and other encumbrances (other than liens, charges, security interests and other encumbrances created by the Holders).

(a) Shares of Series A-1 Preferred Stock shall be evidenced by certificates, which shall bear a legend substantially to the following effect:

(b) Upon request of a holder of Series A Preferred Stock or Class A Common Stock subject to this Series A-1 Certificate of Designations, upon receipt by the Company of an opinion of counsel reasonably satisfactory to the Company to the effect that such legend is no longer required under the Securities Act and applicable state laws, the Company shall promptly cause the legend to be removed from any certificate for any Series A Preferred Stock issued or Class A Common Stock to be issued pursuant to the terms of this Series A-1 Certificate of Designations. Each Initial Investor acknowledges that the Series A Preferred Stock issued pursuant to this Series A-1 Certificate of Designations and the Class A Common Stock or Series A Preferred Stock issuable upon conversion of (or as dividends on) such stock have not been registered under the Securities Act or under any state securities laws and agrees that it will not sell or otherwise dispose of any of the Series A Preferred Stock issued pursuant to this Series A-1 Certificate of Designations or any Class A Common Stock or Series A-1 Preferred Stock issuable upon conversion of (or as dividends on) such stock, except in compliance with the registration requirements or exemption provisions of the Securities Act and any other applicable securities laws.

Each Series A-1 Preferred Stock certificate shall be dated the date of its authentication.

(c) The Company shall replace any mutilated Series A-1 Preferred Stock certificate at the Holder’s expense upon surrender of that certificate to the Company. The Company shall replace certificates that become destroyed, stolen or lost at the Holder’s expense upon delivery to the Company of satisfactory evidence that the certificate has been destroyed, stolen or lost, together with any indemnity that may reasonably be required by the Company.

(d) Notwithstanding anything to the contrary herein, unless requested in writing by a Holder to the Company, shares of Common Stock issued upon conversion of shares of Preferred Stock shall be in uncertificated, book entry form as permitted by the Bylaws of the Company and the Delaware General Corporation Law.

(a) Subject to Section 4.2 of the Securities Purchase Agreement and Section 15(b) hereof, the Holders may Transfer to any Person any portion of their Series A-1 Preferred Stock issued pursuant to this Series A-1 Certificate of Designations or any Class A Common Stock or Series A-1 Preferred Stock, as applicable, issued upon conversion of (or as dividends on) the Series A-1 Preferred Stock issued pursuant to this Series A-1 Certificate of Designations; provided, that no Investor (other than the Initial Investors) shall have the right to participate in the appointment of Investor Directors as set forth in Section 4.4 of the Securities Purchase Agreement and Section 19 herein and Section 19 of the Series A-2 Certificate of Designations unless they have qualified as Approved Holders.

(b) Notwithstanding Section 15(a), the Holders will not at any time knowingly Transfer any Series A-1 Preferred Stock or any Class A Common Stock issued upon conversion of the Series A Preferred Stock pursuant to this Series A-1 Certificate of Designations, held by such Investor to a Company Competitor; provided, however, that this Section 15(b) shall not restrict any Transfer into the public market.

Section 16. Short-Selling. Prior to [●], 2020, no Holder or any Affiliates of such Holder may, directly or indirectly, sell “short” the Common Stock or securities convertible into or exercisable or exchangeable for Common Stock held by it.

(i) any reclassification, statutory exchange, merger, amalgamation, consolidation or other similar business combination of the Company with or into another Person, in each case, pursuant to which Class A Common Stock (but not the Series A-1 Preferred Stock) are changed or converted into, or exchanged for, or represent solely the right to receive, cash, securities or other property;

(ii) any sale, transfer, lease or conveyance to another Person of all or substantially all the property and assets of the Company, in each case pursuant to which Class A Common Stock (but not Series A-1 Preferred Stock) are converted into cash, securities or other property; or

(iii) any statutory exchange of securities of the Company with another Person (other than in connection with a merger or amalgamation) or reclassification, recapitalization or reorganization of the Class A Common Stock (but not the Series A-1 Preferred Stock) into other securities,

(each of which is referred to as a “Reorganization Event,” and such cash, securities or other property, the “Exchange Property,” and the kind and amount of Exchange Property that a holder of one share of Class A Common Stock would be entitled to receive on account of such Reorganization Event (without giving effect to any arrangement not to issue fractional shares of securities or other property), an “Exchange Property Unit”), then, at the effective time of such Reorganization Event, without the consent of the Holders, and subject to Section 17(b), the consideration due upon conversion of Series A-1 Preferred Stock, the adjustments to the Conversion Price and the determination of the kind and amount of dividends that Holders will be entitled to receive pursuant to Section 4(b), will be determined in the same manner as if each reference to any number of shares of Class A Common Stock in this Series A-1 Certificate of Designations were instead a reference to the same number of Exchange Property Units. If such Reorganization Event provides for different treatment of shares of Class A Common Stock held by Affiliates of the Company and non-Affiliates or by the Person with which the Company amalgamated or consolidated or into which the Company merged or which merged into the Company or to which such sale or transfer was made, as the case may be (any such Person, a “Constituent Person”), or an Affiliate of a Constituent Person, then the composition of the Exchange Property and the Exchange Property Unit will be determined based on the cash, securities or other property that were distributed in such Reorganization Event to holders of Class A Common Stock that are not Constituent Persons or Affiliates of the Company or Constituent Persons. In addition, if the kind or amount of cash, securities or other property receivable upon a Reorganization Event is not the same for each share of Class A Common Stock held immediately prior to such Reorganization Event by a Person other than a Constituent Person or an Affiliate of the Company or a Constituent Person, then for the purpose of this Section 17(a), the composition of the Exchange Property and the Exchange Property Unit will be determined based on the weighted average, as determined by the Company in good faith, of the types and amounts of consideration received by the holders of Class A Common Stock.

(b) In the event that the holders of Class A Common Stock have the opportunity to elect the form of consideration to be received in a Reorganization Event, the Exchange Property that the Holders shall be entitled to receive shall be determined by Holders of a majority of outstanding shares of Series A-1 Preferred Stock on or before the earlier of (i) the deadline for elections by holders of Class A Common Stock and (ii) two Business Days before the anticipated effective date of such Reorganization Event.

(d) The Company (or any successor) shall, no less than 20 Business Days prior to the occurrence of any Reorganization Event, provide written notice to the Holders of

such occurrence of such event and of the kind and amount of the cash, securities or other property that constitutes the Exchange Property and the Exchange Property Unit, and shall provide such other information related to the Reorganization Event as Holders may reasonably request. Failure to deliver such notice shall not affect the operation of this Section 17.

(e) The Company shall not enter into any agreement for a transaction constituting a Reorganization Event unless (i) such agreement provides for or does not interfere with or prevent (as applicable) conversion of the Series A-1 Preferred Stock into the Exchange Property in a manner that is consistent with and gives effect to this Section 17, and (ii) to the extent that the Company is not the surviving Company in such Reorganization Event or will be dissolved in connection with such Reorganization Event, proper provision shall be made in the agreements governing such Reorganization Event for the conversion of the Series A-1 Preferred Stock into Exchange Property and, in the case of a Reorganization Event described in Section 17(a)(ii), an exchange of shares of Series A Preferred Stock for the shares of the Person to whom the Company’s assets are conveyed or transferred, having voting powers, preferences, and relative, participating, optional or other special rights as nearly equal as possible to those provided in this Series A-1 Certificate of Designations.

(a) As of the Issue Date, the Board of Directors has increased the size of the Board of Directors by one director (to nine total directors) and caused Phillip Z.

(c) The rights to designate directors pursuant to Section 19(b) shall be held by the Approved Holder Majority, the Initial Investors, and any subsequent Investor designated by an Approved Holder who is approved by the Company in the Company’s sole and absolute discretion (such holders, collectively, the “Approved Holders”).

(e) The Company shall take all actions within its power to cause all designees designated pursuant to Section 19(b) to be included in the slate of nominees recommended by the Board of Directors to the holders of Class A Common Stock for election as directors at each meeting of the Company Stockholders called for the purpose of electing directors (and/or in connection with any election by written consent) and using commercially reasonable efforts to cause the election of each such designated Investor Directors, including (i) voting or providing a written consent or proxy with respect to Common Stock, and soliciting proxies in favor of the election of such nominees, (ii) causing the adoption of stockholders’ resolutions and amendments to the organizational documents of the Company, (iii) executing required agreements and instruments, (iv) making, or causing to be made, with governmental, administrative or regulatory authorities, all filings, registrations or similar actions that are required to achieve such result and (v) for so long as the Approved Holders retain the right described under Section 19(b), not nominating or recommending the election of any other candidates against or in replacement of such designated Investor Directors.

(f) Each Investor Director and Investor Observer designated pursuant to Section 19(b) shall serve until his or her successor is designated or his or her earlier death, disability, resignation or removal; any vacancy or newly created directorship in the position of an Investor Director may be filled only by the Approved Holder Majority, subject to the fulfillment of the requirements set forth in Section 19(g); and each Investor Director and Investor Observer may, during his or her term of office, be removed at any time, with or without cause, by and only by the Approved Holder Majority.

(i) The right to designate directors pursuant to Section 19(b) shall automatically terminate at such time as the Approved Holders no longer Beneficially Own a sufficient number of shares required to designate an Investor Director set forth in Section 19(b)(ii), and at such time, if requested in writing by the Company, any Investor Directors or Investor Observer then serving on the Board of Directors in excess of the entitled amount (if less than all then Investor Directors or Investor Observers, then as selected by the Approved Holder Majority) shall promptly resign from the Board of Directors.

(j) Nothing in this Section 19 shall be deemed to require that any party hereto, or any Affiliate thereof, act or be in violation of any applicable provision of law, regulation, legal duty or requirement or stock exchange or stock market rule.

(k) If, after termination of this Series A-1 Certificate of Designation and the Series A-2 Certificate of Designations or such time as no shares of Series A Preferred Stock remain outstanding, the Approved Holder Majority continues to satisfy the ownership percentages set forth in Section 19(b) and Section 20, the Approved Holder Majority may request the Company to enter into a shareholder agreement reflecting the rights set forth in such sections, which the Company and the Approved Holders shall enter into as promptly as practicable after such request (but, in any event, no later than 30 days after such request).

(l) To the fullest extent permitted by applicable law, the Company, on behalf of itself and its subsidiaries, renounces any interest or expectancy of the Company and its subsidiaries in, or in being offered an opportunity to participate in, any business opportunities that are from time to time presented to the Investors or any of their respective Affiliates or any of their respective agents, shareholders, members, partners, directors, officers, employees, Affiliates or subsidiaries (other than the Company and its subsidiaries), including any director or officer of the Company who is also an agent, shareholder, member, partner, director, officer, employee, Affiliate or subsidiary of any Investor (each, a “Specified Party”), even if the business opportunity is one that the Company or its subsidiaries might reasonably be deemed to have pursued or had the ability or desire to pursue if granted the opportunity to do so, and no Specified Party shall have any duty to communicate or offer any such business opportunity to the Company or be liable to the Company or any of its subsidiaries or any stockholder, including for breach of any fiduciary or other duty, as a director or officer or controlling stockholder or otherwise, and the Company shall indemnify each Specified Party against any claim that such Person is liable to the Company or its stockholders for breach of any fiduciary

Dividends payable pursuant to this Section 4(c), if, when and as declared by the Board of Directors, will be, for each outstanding share of Series A-2 Preferred Stock, payable, subject to Section 4(d), in cash as follows:

(i) Dividends at an amount equal to an annual rate equal to the Dividend Rate multiplied by the sum of (A) the Stated Value and (B), without duplication, the amount of Unpaid Dividends, on such share of Series A-2 Preferred Stock, payable in cash.

(ii) Dividends payable pursuant to this Section 4(c) will be computed on the basis of a 360-day year of twelve 30-day months and, for any Dividend Period greater or

less than a full Dividend Period, will be computed on the basis of the actual number of days elapsed in the period divided by 90. The period from the Issue Date to and including [June 30, 2017]/[the Dividend Payment Date next succeeding the Issue Date] and each period from, but excluding, a Dividend Payment Date to, and including, the following Dividend Payment Date is herein referred to as a “Dividend Period.” Dividends payable pursuant to this Section 4(c) are cumulative. Such dividends shall begin to accrue and be cumulative from the Issue Date, shall compound at the relevant rate on each subsequent Dividend Payment Date (i.e., no dividends shall accrue on another dividend unless and until the first Dividend Payment Date for such other dividends has passed without such other dividends having been paid on such date, in which case dividends will accrue on such Unpaid Dividends) and shall be payable quarterly in arrears on each Dividend Payment Date, commencing with the first such Dividend Payment Date.

(iii) If the Conversion Date with respect to any share of Series A-2 Preferred Stock is prior to the Record Date for any dividend, the Holder of such shares will not be entitled to any such dividend, subject to any Unpaid Dividends being taken into account in Section 7. If the Conversion Date with respect to any share of Series A-2 Preferred Stock is after the Record Date for any dividend but before the corresponding Dividend Payment Date, the Holder of such share of Series A-2 Preferred Stock shall have the right to receive such dividend, notwithstanding the conversion of such shares prior to the Dividend Payment Date.

(i) Notwithstanding anything to the contrary in Section 4(c), for no more than 12 Dividend Periods (whether consecutive or non-consecutive) prior to [●], 2024 (a “PIK Quarter”), the Company may, at its option and in its sole discretion as exercised by the Board of Directors, with respect to all or any portion of the accrued, declared and payable dividends for such Dividend Period, elect to (A) pay such dividends in the form of additional shares of Series A-2 Preferred Stock at a per share price equal to $975.00 or, (B) in lieu of paying such dividends, increase the Stated Value of the applicable shares of Series A-2 Preferred Stock by an amount equal to the accrued and payable dividends on such shares for such applicable PIK Quarter. If the Company fails to fully declare and pay in cash by the Dividend Payment Date, or is unable to fully pay in cash by such date, the accrued dividends with respect to a Dividend Period then, with respect to any unpaid portion but subject to Section 4(e), (x) to the extent any of the 12 PIK Quarters remain available, the Company shall be deemed to have made an election under Section 4(d)(i)(B) and (y) to the extent none of the 12 PIK Quarters remain available, the Stated Value shall be automatically increased by an amount equal to the lesser of (i) a Dividend Rate of 9.0% per annum and (ii) the unpaid portion of any such accrued dividends (provided that any amounts which increase the Stated Value hereby shall no longer be considered Unpaid Dividends), with any remaining unpaid portion in excess of such increase in Stated Value remaining Unpaid Dividends.

(ii) For the avoidance of doubt, any portion of a declared dividend not paid as provided in the foregoing clauses will be paid in cash.

(i) Except as permitted by Section 4(d)(i), if, at any time, the Company fails to fully declare and pay all accrued dividends in cash on a Dividend Payment Date, then the Dividend Rate on the Series A-2 Preferred Stock shall automatically increase by (A) 5.0% per annum effective as of the first day of the applicable Dividend Period and (B) an additional 1.0% for each successive Dividend Period in which the Company so fails to fully declare and pay, up to the maximum Dividend Rate of 20.0% per annum (including any adjustments pursuant to Section 4(e)(ii)). Dividends on the Series A-2 Preferred Stock shall accrue at the increased Dividend Rate for so long until the Company shall have paid dividends at such increased Dividend Rate fully in cash in accordance with Section 4(c) for two consecutive Dividend Periods, upon which time the Dividend Rate on Series A-2 Preferred Stock shall automatically decrease and revert to 9.0% per annum to the extent dividends continue to be paid fully in cash.

(ii) If the Requisite Stockholder Approval is not obtained on or prior to [●], 2017, then the Dividend Rate shall automatically increase by 5.0% commencing on the first day of the Dividend Period ended on [●], 2017/2018, and thereafter, shall increase by an additional 0.5% each subsequent Dividend Period until such Requisite Stockholder Approval is obtained, at which point the Dividend Rate shall be reduced to 9.00% (subject to any adjustment pursuant to Section 4(e)(i)); provided, that in no event shall the applicable Dividend Rate exceed 20.0% per annum (including any adjustments pursuant to Section 4(e)(i)).

(a) In the event of any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company, Holders shall be entitled to receive out of the assets of the Company or proceeds thereof legally available for distribution to stockholders of the Company, after satisfaction of all liabilities, if any, to creditors of the Company and subject to Section 5(b) and to the rights of holders of any shares of capital stock of the Company then outstanding ranking senior to the Series A-2 Preferred Stock in respect of distributions upon liquidation, dissolution or winding up of the Company, and before any distribution of such assets or proceeds is made to or set aside for the holders of Common Stock and any other Junior Securities, a liquidating distribution in an amount equal to the greater of (i) the Stated Value plus, without duplication, Unpaid Dividends, per share and (ii) the amount of the liquidating distributions, as determined by the Board of Directors (or the trustee or other Person or Persons administering the liquidation, dissolution or winding-up of the Company in accordance with applicable law), that would be made on the number of shares of Class A Common Stock underlying shares of Series A-1 Preferred Stock into which such shares of Series A-2 Preferred Stock are convertible immediately before such liquidation, dissolution or winding-up of the Company. After payment of the full amount of such liquidation distribution, the Holders shall not be entitled to any further participation in any distribution of assets by the Company.

(b) In the event the assets of the Company available for distribution to stockholders upon any liquidation, dissolution or winding-up of the affairs of the Company, whether voluntary or involuntary, shall be insufficient to pay in full the amounts payable with respect to all outstanding shares of the Series A-2 Preferred Stock and the corresponding amounts payable on any Parity Securities, Holders and the holders of such Parity Securities shall share ratably in any distribution of assets of the Company in proportion to the full respective liquidating distributions to which they would otherwise be respectively entitled.

Section 6. Maturity. The Series A-2 Preferred Stock shall be perpetual unless converted or redeemed in accordance with this Series A-2 Certificate of Designations.

Section 7. Conversion. Upon obtaining the Requisite Stockholder Approval, each share of Series A-2 Preferred Stock shall automatically convert into that number of duly authorized, validly issued, fully paid and nonassessable shares of Series A-1 Preferred Stock (which such Series A-1 Preferred Stock, shall, for the avoidance of doubt, have a Conversion Price equal to the outstanding Series A-1 Preferred Stock) (such date, the “Conversion Date”) equal to (A) (1) the sum of the Stated Value of a share of Series A-2 Preferred Stock plus, to the extent payable to the Holder pursuant to Section 4(c)(iii) and without duplication, Unpaid Dividends thereon (whether or not declared) divided by (2) the sum of the Stated Value of a share of Series A-1 Preferred Stock plus, without duplication, accrued and unpaid dividends thereon (whether or not declared) plus (B) cash in lieu of fractional shares, if any. For the avoidance of doubt and notwithstanding anything in this Series A-2 Certificate of Designations to the contrary, at no time shall Holders of Series A-2 Preferred Stock have the right to convert any share of their Series A-2 Preferred Stock, and no shares of Series A-2 Preferred Stock are convertible into, Common Stock.

(a) On the Conversion Date, certificates representing the number of shares of Series A-1 Preferred Stock into which the applicable shares of Series A-2 Preferred Stock are converted shall be promptly issued and delivered to the Holder thereof or such Holder’s designee upon presentation and surrender of the certificate evidencing the Series A-2 Preferred Stock, if any (or, if such certificate or certificates have been lost, stolen, or destroyed, a lost certificate affidavit and indemnity in form and substance reasonably acceptable to the Company), to the Company and, if required, the furnishing of appropriate endorsements and transfer documents and the payment of all transfer and similar taxes, if any, allocable to the Holder pursuant to Section 18(b).

(b) From and after the Conversion Date, the shares of Series A-2 Preferred Stock to be converted on the Conversion Date, as applicable, will cease to be entitled to any dividends that may thereafter be declared on such Series A-2 Preferred Stock; such shares of Series A-2 Preferred Stock will no longer be deemed to be outstanding for any purpose; and all

rights (except the right to receive from the Company the Series A-1 Preferred Stock or Class A Common Stock (and cash in lieu of fractional shares, if applicable) upon conversion thereof and any dividends previously declared or otherwise accrued on the Series A-2 Preferred Stock but not paid) of the Holder of such shares of Series A-2 Preferred Stock to be converted shall cease and terminate with respect to such shares. Prior to the Conversion Date, except as otherwise provided herein, Holders shall have no rights as owners of the Series A-1 Preferred Stock (or other relevant capital stock or equity interest into which the Series A-2 Preferred Stock may then be convertible in accordance herewith) (including voting powers, conversion rights and rights to receive any dividends or other distributions on the Series A-1 Preferred Stock or other securities issuable upon conversion) by virtue of holding shares of Series A-2 Preferred Stock.

(c) Shares of Series A-2 Preferred Stock duly converted in accordance with this Series A-2 Certificate of Designations, or otherwise reacquired by the Company.

(d) The Person or Persons entitled to receive the Series A-1 Preferred Stock and/or cash issuable upon conversion of Series A-2 Preferred Stock shall be treated for all purposes as the record holder(s) of such shares of Series A-1 Preferred Stock and/or securities as of the Close of Business on the Conversion Date with respect thereto. In the event that a Holder shall not by written notice designate the name in which shares of Series A-1 Preferred Stock and/or cash to be issued or paid upon conversion of shares of Series A-2 Preferred Stock should be registered or paid or the manner in which such shares should be delivered, the Company shall be entitled to register and deliver such shares, and make such payment, in the name of the Holder and in the manner shown on the records of the Company.

(e) In the event that fewer than all of the shares of Series A-2 Preferred Stock held by any Holder who have requested to have a certificate representing its shares of Series A-2 Preferred Stock are converted pursuant to Section 7, then a new certificate representing the unconverted shares of Series A-2 Preferred Stock shall be issued to such Holder concurrently with the issuance of the certificates representing the applicable Series A-1 Preferred Stock.

(a) After [●], 2020, the Company may, at its option and in its sole discretion, redeem shares of Series A-2 Preferred Stock, in minimum increments of 5,000 shares and even multiples thereof (or such lesser amount in the event that fewer than 5,000 shares remain outstanding), for cash as follows:

(i) prior to [●], 2021, in an amount equal to 110% of the Stated Value plus, without duplication, any Unpaid Dividends;

(ii) prior to [●], 2022, in an amount equal to 105% of the Stated Value plus, without duplication, any Unpaid Dividends; and

(iii) after [●], 2022, in an amount equal to the Stated Value plus, without duplication, any Unpaid Dividends.

(b) The Company shall provide written notice (the “Redemption Notice”) to the Holders at least 30 calendar days prior to any optional redemption in accordance with Section 10(a); provided that nothing in the Redemption Notice shall prohibit the conversion into Series A-1 Preferred Stock pursuant to Section 7 prior to the Company’s proposed redemption date. If the Company elects to redeem fewer than all of the outstanding shares of Preferred Stock pursuant to this Section 10, the Series A-2 Preferred Stock will be redeemed on a pro rata basis across all Holders based on their respective ownership of Series A-2 Preferred Stock unless agreed upon otherwise by the Holders. The shares of Series A-2 Preferred Stock Preferred Stock not redeemed shall remain outstanding.

(c) If the Requisite Stockholder Approval is not obtained and the Series A-2 Preferred Stock not converted to Series A-1 Preferred Stock, on or prior to the seventh anniversary of the Issue Date, then the Company shall, on such seventh anniversary of the Issue Date, redeem all of the outstanding shares of Series A-2 Preferred Stock for a cash amount per share equal to the Stated Value plus, without duplication, any Unpaid Dividends.

(d) Any shares of Series A-2 Preferred Stock that are redeemed or otherwise acquired by the Company shall be cancelled upon payment therefor and will resume the status of authorized and unissued shares of Preferred Stock, undesignated as to series, and will be available for future issuance, but shall not be reissued as shares of Series A-2 Preferred Stock. If only a portion of the shares of Series A-2 Preferred Stock represented by a certificate shall have been called for redemption, upon surrender of the certificate to the Company, the Company shall issue and deliver to the Holders a new certificate representing the number of shares of Series A-2 Preferred Stock represented by the surrendered certificate that have not been called for redemption.

(a) The Holders shall be entitled to (i) vote with the holders of the Class A Common Stock on all matters submitted for a vote of holders of Class A Common Stock, (ii) when voting with the Class A Common Stock, a number of votes equal to the number of shares of Class A Common Stock such Holder would hold on an “as-converted basis” (as if each such shares of Series A-2 Preferred Stock have been converted into shares of Series A-1 Preferred Stock pursuant to the terms of this Series A-2 Certificate of Designations) on the Record Date for the determination of the holders of Class A Common Stock entitled to vote on the matter in question and (iii) notice of all stockholders’ meetings in accordance with the Certificate of Incorporation and Bylaws of the Company, and applicable law or regulation or stock exchange rule, as if the Holders of Series A-2 Preferred Stock were holders of Class A Common Stock.

(b) Each Holder will have one vote per share on any matter on which Holders of Series A-2 Preferred Stock are entitled to vote separately as a class, whether at a meeting or by written consent.

(c) So long as any shares of Series A-2 Preferred Stock are outstanding, in addition to any other vote or consent of stockholders required by law or the Certificate of Incorporation, the affirmative vote or consent of Holders of at least a majority of the

outstanding shares of Series A-2 Preferred Stock, voting together as a separate class, given in person or by proxy, either in writing without a meeting or by vote at any meeting called for the purpose, shall be necessary for effecting or validating any amendment, modification or alteration of, or supplement to, the Certificate of Incorporation or this Series A-2 Certificate of Designations that would materially and adversely affect the relative rights, preferences, privileges or voting powers of the Series A-2 Preferred Stock or any Holder.

(a) The Company shall at all times reserve and keep available out of its authorized and unissued Series A-1 Preferred Stock and Class A Common Stock or shares of Series A-1 Preferred Stock and Class A Common Stock acquired by the Company and not retired, solely for issuance upon the conversion of shares of Series A-2 Preferred Stock as provided in this Series A-2 Certificate of Designations and the further conversion of shares of Series A-1 Preferred Stock resulting from such conversion as provided in the Series A-1 Certificate of Designations, such number of shares of Series A-1 Preferred Stock and such number of shares of Class A Common Stock as shall from time to time be issuable upon the conversion of all the shares of Series A-2 Preferred Stock then outstanding and upon the conversion of all the shares of Series A-1 Preferred Stock resulting from such conversion. The Company shall take all such corporate and other actions as from time to time may be necessary to ensure that all shares of Series A-1 Preferred Stock issuable upon conversion of shares of Series A-2 Preferred Stock and all shares of Class A Common Stock issuable upon conversion of shares of Series A-1 Preferred Stock resulting from such conversion will, upon issue, be duly and validly authorized and issued, fully paid and nonassessable. For purposes of this Section 13, the number of shares of Series A-1 Preferred Stock and the number of shares of Class A Common Stock that shall be deliverable upon the conversion of all outstanding shares of Series A-2 Preferred Stock and the further conversion of all resulting Series A-1 Preferred Stock into Class A Common Stock shall be computed as if at the time of computation all such outstanding shares were held by a single Holder.

(b) Notwithstanding the foregoing, the Company shall be entitled to deliver upon conversion of shares of Series A-2 Preferred Stock, as herein provided, shares of Series A-1 Preferred Stock acquired and not retired by the Company (in lieu of the issuance of authorized and unissued shares of Series A-1 Preferred Stock), so long as any such acquired shares are free and clear of all liens, charges, security interests or encumbrances (other than liens, charges, security interests and other encumbrances created by the Holders).

(c) All shares of Series A-1 Preferred Stock delivered upon conversion of the Series A-2 Preferred Stock shall be duly authorized, validly issued, fully paid and non-assessable, free and clear of all liens, claims, security interests and other encumbrances (other than liens, charges, security interests and other encumbrances created by the Holders).

(a) Shares of Series A-2 Preferred Stock shall be evidenced by certificates, which shall bear a legend substantially to the following effect:

(b) Upon request of a holder of Series A Preferred Stock or Class A Common Stock subject to this Series A-2 Certificate of Designations, upon receipt by the Company of an opinion of counsel reasonably satisfactory to the Company to the effect that such legend is no longer required under the Securities Act and applicable state laws, the Company shall promptly cause the legend to be removed from any certificate for any Series A Preferred Stock issued or Class A Common Stock to be issued pursuant to the terms of this Series A-2 Certificate of Designations. Each Initial Investor acknowledges that the Series A Preferred Stock issued pursuant to this Series A-2 Certificate of Designations and the Class A Common Stock or Series A Preferred Stock issuable upon conversion of (or as dividends on) such stock have not been registered under the Securities Act or under any state securities laws and agrees that it will not sell or otherwise dispose of any of the Series A Preferred Stock issued pursuant to this Series A-2 Certificate of Designations or any Class A Common Stock or Series A-2 Preferred Stock issuable upon conversion of (or as dividends on) such stock, except in compliance with the registration requirements or exemption provisions of the Securities Act and any other applicable securities laws.

Each Series A-2 Preferred Stock certificate shall be dated the date of its authentication.

(c) The Company shall replace any mutilated Series A-2 Preferred Stock certificate at the Holder’s expense upon surrender of that certificate to the Company. The Company shall replace certificates that become destroyed, stolen or lost at the Holder’s expense upon delivery to the Company of satisfactory evidence that the certificate has been destroyed, stolen or lost, together with any indemnity that may reasonably be required by the Company.

(a) Subject to Section 4.2 of the Securities Purchase Agreement and Section 15(b) hereof, the Holders may Transfer to any Person any portion of their Series A-2 Preferred Stock issued pursuant to this Series A-2 Certificate of Designations or any Class A Common Stock or Series A-2 Preferred Stock, as applicable, issued upon conversion of (or as dividends on) the Series A-2 Preferred Stock issued pursuant to this Series A-2 Certificate of Designations; provided, that no Investor (other than the Initial Investors) shall have the right to participate in the appointment of Investor Directors as set forth in Section 4.4 of the Securities Purchase Agreement and Section 19 herein and Section 19 of the Series A-1 Certificate of Designations unless they have qualified as Approved Holders.

(b) Notwithstanding Section 15(a), the Holders will not at any time knowingly Transfer any Series A-2 Preferred Stock or any Class A Common Stock issued upon conversion of the Series A Preferred Stock pursuant to this Series A-2 Certificate of Designations, held by such Investor to a Company Competitor; provided, however, that this Section 15(b) shall not restrict any Transfer into the public market.

(i) any reclassification, statutory exchange, merger, amalgamation, consolidation or other similar business combination of the Company with or into another Person, in each case, pursuant to which Series A-1 Preferred Stock (but not the Series A-2 Preferred Stock) are changed or converted into, or exchanged for, or represent solely the right to receive, cash, securities or other property;

(ii) any sale, transfer, lease or conveyance to another Person of all or substantially all the property and assets of the Company, in each case pursuant to which Series A-1 Preferred Stock (but not Series A-2 Preferred Stock) are converted into cash, securities or other property; or

(iii) any statutory exchange of securities of the Company with another Person (other than in connection with a merger or amalgamation) or reclassification, recapitalization or reorganization of the Series A-1 Preferred Stock (but not the Series A-2 Preferred Stock) into other securities,

securities or other property), an “Exchange Property Unit”), then, at the effective time of such Reorganization Event, without the consent of the Holders, and subject to Section 17(b), the consideration due upon conversion of Series A-2 Preferred Stock, the adjustments to the Conversion Price and the determination of the kind and amount of dividends that Holders will be entitled to receive pursuant to Section 4(b), will be determined in the same manner as if each reference to any number of shares of Class A Common Stock in this Series A-2 Certificate of Designations were instead a reference to the same number of Exchange Property Units. If such Reorganization Event provides for different treatment of shares of Class A Common Stock held by Affiliates of the Company and non-Affiliates or by the Person with which the Company amalgamated or consolidated or into which the Company merged or which merged into the Company or to which such sale or transfer was made, as the case may be (any such Person, a “Constituent Person”), or an Affiliate of a Constituent Person, then the composition of the Exchange Property and the Exchange Property Unit will be determined based on the cash, securities or other property that were distributed in such Reorganization Event to holders of Class A Common Stock that are not Constituent Persons or Affiliates of the Company or Constituent Persons. In addition, if the kind or amount of cash, securities or other property receivable upon a Reorganization Event is not the same for each share of Class A Common Stock held immediately prior to such Reorganization Event by a Person other than a Constituent Person or an Affiliate of the Company or a Constituent Person, then for the purpose of this Section 17(a), the composition of the Exchange Property and the Exchange Property Unit will be determined based on the weighted average, as determined by the Company in good faith, of the types and amounts of consideration received by the holders of Class A Common Stock.

(b) In the event that the holders of Class A Common Stock have the opportunity to elect the form of consideration to be received in a Reorganization Event, the Exchange Property that the Holders shall be entitled to receive shall be determined by Holders of a majority of outstanding shares of Series A-2 Preferred Stock on or before the earlier of (i) the deadline for elections by holders of Class A Common Stock and (ii) two Business Days before the anticipated effective date of such Reorganization Event.

(d) The Company (or any successor) shall, no less than 20 Business Days prior to the occurrence of any Reorganization Event, provide written notice to the Holders of such occurrence of such event and of the kind and amount of the cash, securities or other property that constitutes the Exchange Property and the Exchange Property Unit, and shall provide such other information related to the Reorganization Event as Holders may reasonably request. Failure to deliver such notice shall not affect the operation of this Section 17.

Stock into Exchange Property and, in the case of a Reorganization Event described in Section 17(a)(ii), an exchange of shares of Series A Preferred Stock for the shares of the Person to whom the Company’s assets are conveyed or transferred, having voting powers, preferences, and relative, participating, optional or other special rights as nearly equal as possible to those provided in this Series A-2 Certificate of Designations.

Section 19. Board Representation Rights. The Approved Holders shall be entitled to the rights set forth in Section 19 of the Series A-1 Certificate of Designations, if and as applicable, even if such Series A-1 Certificate of Designations is then no longer in effect.

Section 20. Investor Consent. The Approved Holders shall be entitled to the rights set forth in Section 20 of the Series A-1 Certificate of Designations even if such Series A-1 Certificate of Designations is then no longer in effect.

(a) All notices referred to herein shall be in writing, and, unless otherwise specified herein, all notices hereunder shall be deemed to have been given upon the earlier of receipt thereof or three Business Days after the mailing thereof if sent by registered or certified mail with postage prepaid, addressed: (i) if to the Company, to its office at 600 Bailey Avenue, Suite 200, Fort Worth, Texas 76107 or (ii) if to any Holder, to such Holder at the address of such Holder as listed in the stock record books of the Company, or (iii) to such other address as the Company or any such Holder, as the case may be, shall have designated by notice similarly given.

(b) The Company shall pay any and all stock transfer and documentary stamp taxes that may be payable in respect of any issuance or delivery of shares of Series A-2 Preferred Stock or shares of Series A-1 Preferred Stock or other securities issued on account of Series A-2 Preferred Stock pursuant hereto or certificates representing such shares or securities. The Company shall not, however, be required to pay any such tax that may be payable in respect of any transfer involved in the issuance or delivery of shares of Series A-2 Preferred Stock or Series A-1 Preferred Stock or other securities in a name other than that in which the shares of Series A-2 Preferred Stock with respect to which such shares or other securities are issued or delivered were registered, or in respect of any payment to any Person other than a payment to the registered holder thereof, and shall not be required to make any such issuance, delivery or payment unless and until the Person otherwise entitled to such issuance, delivery or payment has paid to the Company the amount of any such tax or has established, to the reasonable satisfaction of the Company, that such tax has been paid or is not payable.

(c) No share of Series A-2 Preferred Stock shall have any rights of preemption whatsoever as to any securities of the Company, or any warrants, rights or options issued or granted with respect thereto, regardless of how such securities, or such warrants, rights or options, may be designated issued or granted.

(d) The shares of Series A-2 Preferred Stock shall not have any voting powers, preferences or relative, participating, optional or other special rights, or qualifications, limitations or restrictions thereof, other than as set forth herein or in the Certificate of Incorporation or as provided by applicable law or the Securities Purchase Agreement.

The Company shall use its commercially reasonable efforts to cause the Shelf Registration Statement to be declared effective by the Commission as soon as reasonably practicable after the initial filing of the Shelf Registration Statement, but in any event no later than one hundred twenty (120) days after the Filing Deadline (the “Effectiveness Deadline”). The Shelf Registration Statement shall provide for the resale pursuant to any method or combination of methods legally available to, and requested by, the Holders of any and all Registrable Securities covered by such Shelf Registration Statement. The Company shall use its commercially reasonable efforts to cause the Shelf Registration Statement filed pursuant to this Section 2.01 to be continuously effective, supplemented and amended to the extent necessary to ensure that it is available for the resale of all Registrable Securities by the Holders until all Registrable Securities covered by such Shelf Registration Statement have ceased to be Registrable Securities (the “Effectiveness Period”). The Shelf Registration Statement when effective (and the documents incorporated therein by reference) shall comply as to form in all material respects with all applicable requirements of the Securities Act and shall not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. As soon as practicable following the date that the Shelf Registration Statement becomes effective, but in any event within two (2) business days of such date, the Company shall provide the Holders with written notice of the effectiveness of the Shelf Registration Statement. Once a Holder’s Registrable Securities become eligible for resale without restriction and without the need for current public information pursuant to any section of Rule 144 (or any similar provision then in effect) under the Securities Act, assuming the Holder of such Registrable Securities is not an affiliate (as defined in Rule 144(a)(1) under the Securities Act) of the Company, such Holder may, at any time, request that the Company take such steps as are reasonably necessary to deregister such Holder’s Registrable Securities and in connection therewith, such Holder’s rights under this Agreement shall all be terminated, including without limitation the right to demand an Underwritten Offering and the right to participate in a Piggyback Registration Statement and, further, such Holder shall no longer be subject to any obligations under this Agreement, including specifically but not limited to the obligation to enter into letter agreements with underwriters pursuant to Section 2.02.

(b) Notwithstanding anything to the contrary contained herein, the Company may, upon written notice to any Selling Holder whose Registrable Securities are included in a Shelf Registration Statement, suspend such Selling Holder’s use of any prospectus that is a part of such Shelf Registration Statement (in which event the Selling Holder shall suspend sales of the Registrable Securities pursuant to such Shelf Registration Statement) if (i) the Company is pursuing an acquisition, merger, reorganization, disposition or other similar transaction and the

Company determines in good faith that the Company’s ability to pursue or consummate such a transaction would be materially and adversely affected by any required disclosure of such transaction in such Shelf Registration Statement or (ii) the Company has experienced some other material non-public event, the disclosure of which at such time, in the good faith judgment of the Company, would materially and adversely affect the Company; provided, however, that in no event shall the Selling Holders be suspended from selling Registrable Securities pursuant to such Shelf Registration Statement for a period that exceeds an aggregate of forty-five (45) days in any 90-day period or ninety (90) days in any 365-day period. Upon disclosure of such information or the termination of the condition described above, the Company shall provide prompt notice to the Selling Holders whose Registrable Securities are included in such Shelf Registration Statement, and shall promptly terminate any suspension of sales it has put into effect and shall take such other actions necessary or appropriate to permit registered sales of Registrable Securities as contemplated in this Agreement.

(i) Following the Effectiveness Deadline, if the Holders of at least thirty percent (30%) of the then outstanding Registrable Securities elect to dispose of all or any portion of their Registrable Securities pursuant to an Underwritten Offering, the anticipated aggregate offering price, net of underwriting discounts and commissions, of which is in excess of $30,000,000, the Company shall, upon the written request by such Holders, use its commercially reasonable efforts to (A) retain underwriters in order to permit such Holders to effect such sale through an Underwritten Offering (a “Secondary Offering”); (B) if a registration statement is not then already available and effective, prepare and file with the Commission a registration statement under the Securities Act providing for a Secondary Offering as permitted by Rule 415 of the Securities Act with respect to such Registrable Securities (a “Secondary Offering Registration Statement”); and (C) cause such Secondary Offering Registration Statement to be declared effective as soon as reasonably practicable after the initial filing thereof. In addition, the Company shall give prompt written notice (including notice by electronic mail) to each other Holder (and to the Holders under the Existing Registration Rights Agreements) regarding such proposed Secondary Offering, and such notice shall offer such Holders the opportunity to include in such Secondary Offering Registration Statement such number of Registrable Securities as each such Holder may request. Each such notice shall specify, at a minimum, the number and type of securities proposed to be registered, the proposed date of filing of such Secondary Offering Registration Statement with the Commission, the proposed means of distribution, the proposed Secondary Managing Underwriter and other underwriters (if any and if known) and a good faith estimate by the Company of the proposed minimum offering price of such securities (if known). Each such Holder shall make such request in writing to the Company (including by electronic mail) within five (5) business days after the receipt of any such notice from the Company, which request shall specify the number of Registrable Securities intended to be disposed of by such Holder, and, subject to the terms and conditions of this Agreement, including Section 2.02, the Company shall use its reasonable best efforts to include in such Secondary Offering Registration Statement all Registrable Securities held by such Holders.

(ii) The obligation of the Company to retain underwriters shall include the preparation and entry into an underwriting agreement, in customary form, with the Secondary Managing Underwriter and other underwriters, if any, which shall include, among other provisions, indemnities to the effect and to the extent provided in Section 2.07 and customary lock-up provisions for the Company and its directors and officers. The Company shall take all reasonable actions as requested by the Secondary Managing Underwriter or other underwriters (if any) to expedite or facilitate the disposition of such Registrable Securities, including causing its management to participate in a “roadshow” or similar marketing efforts.

(b) Limitation on Offerings. In no event shall the Company be required hereunder to participate in more than four (4) Secondary Offerings pursuant to the terms hereof; provided, that should the Holder or Holders requesting such Secondary Offering be unable to sell at least eighty percent (80%) of the Registrable Securities requested to be included therein pursuant to Section 2.02(c), the Company shall be required to participate in an additional Secondary Offering pursuant to the terms hereof; provided, further, that if a Secondary Offering is commenced but terminated prior to the pricing thereof for any reason, the Company shall be required to participate in an additional Secondary Offering pursuant to the terms hereof.

(c) Priority. If in connection with a Secondary Offering pursuant to this Section 2.02, the Secondary Managing Underwriter shall advise the Company that, in its reasonable opinion, the number of securities requested and otherwise proposed to be included in such Underwritten Offering, including pursuant to the Existing Registration Rights Agreements, exceeds the number that can be sold in such offering without having an adverse effect on the price, timing or distribution of the securities to be offered (an “Adverse Effect”), then the Company shall include in such Underwritten Offering the number of Registrable Securities that such Secondary Managing Underwriter advises the Company can be sold without having such Adverse Effect, with such number to be allocated (i) first, to the Selling Holders, as defined in and pursuant to the Leucadia Registration Rights Agreement, to the Selling Holders, as defined in and pursuant to the Battlecat Registration Rights Agreement, and to the Selling Holders hereunder, pro rata based on the relative number of Registrable Securities (as defined herein or in the Leucadia Registration Rights Agreement or the Battlecat Registration Rights Agreement, as applicable) proposed to be offered and sold by such Selling Holders, and (ii) second, to the Selling Holders, as defined in and pursuant to, the EF Registration Rights Agreement.

(d) Selection of Secondary Managing Underwriter. In connection with any Secondary Offering under this Agreement, the Secondary Managing Underwriter shall be selected by the Holders holding a majority of the Registrable Securities proposed to be sold in such Underwritten Offering, which underwriter shall be reasonably acceptable to the Company.

(e) Withdrawal. If any Selling Holder disapproves of the terms of a Secondary Offering, such Person may elect to withdraw its request that the Company undertake such offering by written notice to the Company; provided, however, that such withdrawal must be made at a time prior to the time of pricing of such offering. No such withdrawal shall affect the Company’s obligation to pay Registration Expenses, if applicable.

(a) Participation. So long as any Holder has Registrable Securities, if the Company proposes to file, whether for its own account or for the account of the Holders, (i) a shelf registration statement (other than a Shelf Registration Statement contemplated by Section 2.01(b)), or (ii) a registration statement (other than a registration statement on Form S-4 or S-8 or any successor forms thereto) (each of (i) and (ii), a “Piggyback Registration Statement”), then the Company shall give prompt written notice (a “Piggyback Notice”) (including notice by electronic mail) to each Holder regarding such proposed registration, and such notice shall offer such Holders the opportunity to include in such Piggyback Registration Statement such number of Registrable Securities as each such Holder may request. Each Piggyback Notice shall specify, at a minimum, the number and type of securities proposed to be registered, the proposed date of filing of such Piggyback Registration Statement with the Commission, the proposed means of distribution, the proposed Primary Managing Underwriter and other underwriters (if any and if known) and a good faith estimate by the Company of the proposed minimum offering price of such securities. Each such Holder shall make such request in writing to the Company (including by electronic mail) within five (5) business days (or one (1) business day in connection with any overnight or bought Underwritten Offering) after the receipt of any such Piggyback Notice, which request shall specify the number of Registrable Securities intended to be disposed of by such Holder, and, subject to the terms and conditions of this Agreement, the Company shall use its commercially reasonable efforts to include in such Piggyback Registration Statement all Registrable Securities held by such Holders; provided, that if, at any time after giving written notice of its intention to file a Piggyback Registration Statement and prior to the effective date of such Piggyback Registration Statement, the Company shall determine for any reason not to have such Piggyback Registration Statement be declared effective, the Company may, at its election, give written notice of such determination within five (5) business days thereof to each Holder of Registrable Securities and, thereupon, shall not be obligated to register any Registrable Securities in connection with such Piggyback Registration Statement (but shall nevertheless pay the Registration Expenses in connection therewith), without prejudice, however, to the rights of the Holders of Registrable Securities that a registration be effected under Section 2.01 or Section 2.02.

(b) Selection of Primary Managing Underwriter. In connection with any Underwritten Offering under this Section 2.03, the Primary Managing Underwriter shall be selected by the Company, which Primary Managing Underwriter shall be reasonably acceptable to the Selling Holders.

(c) Priority. If in connection with an Underwritten Offering pursuant to this Section 2.03, the Primary Managing Underwriter shall advise the Company that, in its reasonable opinion, the number of securities requested and otherwise proposed to be included in such Underwritten Offering, including pursuant to the Existing Registration Rights Agreements, exceeds the number that can be sold in such offering without having an Adverse Effect, then the Company shall include in such Underwritten Offering the number of Registrable Securities that such Primary Managing Underwriter advises the Company can be sold without having such

Adverse Effect, with such number to be allocated (i) first, to the Company, (ii) second, to the Selling Holders, as defined in and pursuant to the Leucadia Registration Rights Agreement, to the Selling Holders, as defined in and pursuant to the Battlecat Registration Rights Agreement, and to the Selling Holders hereunder, pro rata based on the relative number of Registrable Securities (as defined herein or in the Leucadia Registration Rights Agreement or the Battlecat Registration Rights Agreement, as applicable) proposed to be offered and sold by such Selling Holders, and (iii) thereafter, to any holders of registration rights; and fourth, second, and if any, the number of included Registrable Securities that, in the opinion of such Primary Managing Underwriter, can be sold without having such Adverse Effect, with such number to be allocated pro rata among the Holders that have requested to participate in such Underwritten Offering based on the relative number of Registrable Securities then held by each such Holder (provided that any securities thereby allocated to a Holder that exceed such Holder’s request shall be reallocated among the remaining requesting Holders in like manner).

Section 2.04 Sale Procedures. In connection with its obligations under this Article II, the Company will, as expeditiously as possible:

(a) prepare and file with the Commission such amendments and supplements to any Registration Statement and the prospectus used in connection therewith as may be necessary to keep the Registration Statement effective for the Effectiveness Period and as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities covered by such Registration Statement;

(b) if a prospectus supplement, offering memorandum or similar marketing document will be used in connection with the marketing of a Secondary Offering and the Secondary Managing Underwriter notifies the Company in writing that, in the sole judgment of such Secondary Managing Underwriter, inclusion of detailed information in such prospectus supplement is of material importance to the success of such offering, the Company shall use its commercially reasonable efforts to include such information in such prospectus supplement, offering memorandum or similar marketing document;

(c) furnish to each Selling Holder (i) as far in advance as reasonably practicable before filing any Registration Statement or any supplement or amendment thereto, upon request, copies of reasonably complete drafts of all such documents proposed to be filed (including exhibits and each document incorporated by reference therein to the extent then required by the rules and regulations of the Commission), and provide each such Selling Holder the opportunity to object to any information pertaining to such Selling Holder and its plan of distribution that is contained therein and make the corrections reasonably requested by such Selling Holder with respect to such information prior to filing the Registration Statement or supplement or amendment thereto or use of a similar marketing instrument, and (ii) such number of copies of the Registration Statement and the prospectus included therein and any supplements and amendments thereto or similar marketing instrument as such Persons may reasonably request in order to facilitate the public sale or other disposition of the Registrable Securities covered by the Registration Statement;

(d) if applicable, use its commercially reasonable efforts to register or qualify the Registrable Securities covered by the Registration Statement under the securities or blue sky

laws of such jurisdictions as the Selling Holders or, in the case of a Secondary Offering, the Secondary Managing Underwriter, shall reasonably request; provided, however, that the Company will not be required to qualify generally to transact business in any jurisdiction where it is not then required to so qualify or to take any action that would subject it to general service of process in any jurisdiction where it is not then so subject;

(e) promptly notify each Selling Holder and, if applicable, any Secondary Managing Underwriter, at any time when a prospectus is required to be delivered under the Securities Act, of (i) the filing of the Registration Statement or any prospectus or prospectus supplement to be used in connection therewith, or any amendment or supplement thereto, and, with respect to such Registration Statement or any post-effective amendment thereto, when the same has become effective; and (ii) any written comments from the Commission with respect to any filing referred to in clause (i) and any written request by the Commission for amendments or supplements to the Registration Statement or any prospectus or prospectus supplement thereto;

(f) immediately notify each Selling Holder and, if applicable, any Secondary Managing Underwriter, at any time when a prospectus is required to be delivered under the Securities Act, of (i) the happening of any event as a result of which the prospectus or prospectus supplement contained in the Registration Statement or any post-effective amendment thereto, as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any prospectus contained therein, in the light of the circumstances under which a statement is made); (ii) the issuance or threat of issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement, or the initiation of any proceedings for that purpose; or (iii) the receipt by the Company of any notification with respect to the suspension of the qualification of any Registrable Securities for sale under the applicable securities or blue sky laws of any jurisdiction. Following the provision of such notice, the Company agrees to, as promptly as practicable, amend or supplement the prospectus or prospectus supplement or take other appropriate action so that the prospectus or prospectus supplement does not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing and to take such other reasonable action as is necessary to remove a stop order, suspension, threat thereof or proceedings related thereto;

(g) upon a Selling Holder’s request and subject to appropriate confidentiality obligations, furnish to each Selling Holder copies of any and all transmittal letters or other correspondence with the Commission or any other governmental agency or self-regulatory body or other body having jurisdiction (including any domestic or foreign securities exchange) relating to any offering of Registrable Securities;

(h) in the case of an Underwritten Offering, including a Secondary Offering, furnish upon request, (i) an opinion of counsel for the Company dated the date of the closing under the underwriting agreement or purchase agreement, as applicable and (ii) a “comfort” letter, dated the pricing date of such offering (to the extent available) and a letter of like kind dated the date of the closing under the underwriting agreement or purchase agreement, as applicable, in each case, signed by the independent public accountants who have certified the Company’s financial statements included or incorporated by reference into the applicable Registration Statement, and

each of the opinion and the “comfort” letter shall be in customary form and covering substantially the same matters with respect to such Registration Statement (and the prospectus and any prospectus supplement included therein) as have been customarily covered in opinions of issuer’s counsel and in accountants’ letters delivered to the underwriters or placement agents in public offerings or private placements, as applicable, of securities by the Company and such other matters as the Secondary Managing Underwriter or Selling Holders, as applicable, may reasonably request;

(i) otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of the Commission, and make available to its security holders, as soon as reasonably practicable, an earnings statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 promulgated thereunder;

(j) make available to the appropriate representatives of the Selling Holders or the Secondary Managing Underwriter, if any, access to such information and Company personnel as is reasonable and customary to enable such parties to establish a due diligence defense under the Securities Act;

(k) cause all Registrable Securities registered pursuant to this Agreement to be listed on each securities exchange or nationally recognized quotation system on which similar securities issued by the Company are then listed;

(l) use its commercially reasonable efforts to cause the Registrable Securities to be registered with or approved by such other governmental agencies or authorities as may be necessary by virtue of the business and operations of the Company to enable the Selling Holders to consummate the disposition of the Registrable Securities;

(m) provide a transfer agent and registrar for all Registrable Securities covered by any Registration Statement not later than the effective date of such Registration Statement; and

(n) enter into customary agreements and take such other actions as are reasonably requested by the Selling Holders or the Secondary Managing Underwriter, if any, in order to expedite or facilitate the disposition of the Registrable Securities.

Each Selling Holder, upon receipt of notice from the Company of the happening of any event of the kind described in subsection (f) of this Section 2.04, shall forthwith discontinue disposition of the Registrable Securities by means of a prospectus or prospectus supplement until such Selling Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by subsection (f) of this Section 2.04 or until it is advised in writing by the Company that the use of the prospectus may be resumed, and has received copies of any additional or supplemental filings incorporated by reference in the prospectus.

Section 2.05 Cooperation by Holders. The Company shall have no obligation to include in a Registration Statement Registrable Securities of a Selling Holder who has failed to timely furnish such information that, in the opinion of counsel to the Company, is reasonably required in order for a registration statement or prospectus supplement, as applicable, to comply with the Securities Act.

(a) Expenses. The Company will pay all reasonable Registration Expenses of any Registration Statement, any Underwritten Offering or any Secondary Offering, regardless of whether any sale of Registrable Securities is consummated. Each Selling Holder shall pay its pro rata shall of all Selling Expenses in connection with any sale of its Registrable Securities hereunder. For the avoidance of doubt, each Selling Holder’s pro rata allocation of Selling Expenses shall be the percentage derived by dividing (i) the number of Registrable Securities sold by such Selling Holder in connection with such sale by (ii) the aggregate number of Registrable Securities sold by all Selling Holders in connection with such sale.

(b) Certain Definitions. “Registration Expenses” means all expenses incident to the Company’s performance under or compliance with this Agreement to effect the registration of Registrable Securities on any Registration Statement and the disposition of Registrable Securities covered thereby, including, without limitation, all registration, filing, securities exchange listing and securities exchange fees, all registration, filing, qualification and other fees and expenses of complying with securities or blue sky laws, fees of the Financial Industry Regulatory Authority, fees of transfer agents and registrars, all word processing, duplicating and printing expenses, any transfer taxes, any fees and disbursements of counsel and independent public accountants for the Company, including the expenses of any special audits or “cold comfort” letters required by or incident to such performance and compliance, any expenses of any “road shows.” “Selling Expenses” means all underwriting discounts and selling commissions or placement agency fees applicable to the sale of Registrable Securities, and all attorneys’ fees incurred by Holders in connection with the exercise of such Holders’ rights hereunder.

(a) By the Company. In the event of a registration of any Registrable Securities under the Securities Act pursuant to this Agreement, the Company will indemnify and hold harmless each Selling Holder participating therein, its directors, officers, employees and agents, and each Person, if any, who controls such Selling Holder within the meaning of the Securities Act and the Exchange Act, and its directors, officers, employees or agents, against any losses, claims, damages, expenses or liabilities (including reasonable attorneys’ fees and expenses) (collectively, “Losses”), joint or several, to which such Selling Holder, director, officer, employee, agent or controlling Person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such Losses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact (in the case of any prospectus, in light of the circumstances under which such statement is made) contained in the Registration Statement, any preliminary prospectus, prospectus supplement, free writing prospectus or final prospectus contained therein, or any amendment or supplement thereof, 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 (in the case of a prospectus, in light of the circumstances under which they were made) not misleading, and will reimburse each such Selling Holder, its directors, officers, employee and agents, and each such controlling Person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such Loss or actions or proceedings as such expenses are incurred; provided,

however, that the Company will not be liable in any such case if and to the extent that any such Loss arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by such Selling Holder, its directors, officers, employees and agents or such controlling Person in writing specifically for use in the Registration Statement, or prospectus or any amendment or supplement thereto, as applicable. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Selling Holder or any such directors, officers, employees agents or controlling Person, and shall survive the transfer of such securities by such Selling Holder.

(b) By Each Holder. Each Selling Holder agrees severally and not jointly to indemnify and hold harmless the Company and each other Holder, its directors, officers, employees and agents and each Person, if any, who controls the Company or such Holder within the meaning of the Securities Act or of the Exchange Act, and its directors, officers, employees and agents, to the same extent as the foregoing indemnity from the Company to the Selling Holders, but only with respect to information regarding such Selling Holder furnished in writing by or on behalf of such Selling Holder expressly for inclusion in the Registration Statement, any preliminary prospectus, prospectus supplement, free writing prospectus or final prospectus contained therein, or any amendment or supplement thereto; provided, that no Selling Holder shall be required to make any representations or warranties to or agreements with the Company or the underwriters other than representations, warranties or agreements regarding such Selling Holder, its ownership and title to the Registrable Shares and its intended method of distribution. The liability of each Selling Holder under this Section 2.07 shall not be greater in amount than the dollar amount of the proceeds (net of any Selling Expenses) received by such Selling Holder from the sale of the Registrable Securities giving rise to such indemnification.

(c) Notice. Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission to so notify the indemnifying party shall not relieve it from any liability that it may have to any indemnified party other than under this Section 2.07. In any action brought against any indemnified party, it shall notify the indemnifying party of the commencement thereof. The indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 2.07 for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected; provided, however, that, (i) if the indemnifying party has failed to assume the defense or employ counsel reasonably acceptable to the indemnified party or (ii) if the defendants in any such action include both the indemnified party and the indemnifying party and counsel to the indemnified party shall have concluded that there may be reasonable defenses available to the indemnified party that are different from or additional to those available to the indemnifying party, or if the interests of the indemnified party reasonably may be deemed to conflict with the interests of the indemnifying party, then the indemnified party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the reasonable expenses and fees of such separate counsel and other reasonable expenses related to such participation to

be reimbursed by the indemnifying party as incurred. Notwithstanding any other provision of this Agreement, no indemnified party shall settle any action brought against it with respect to which such indemnified party is entitled to indemnification hereunder without the consent of the indemnifying party, unless the settlement thereof imposes no liability or obligation on, and includes a complete and unconditional release from all liability of, the indemnifying party and further, no indemnifying party shall settle any action brought against any indemnified party with respect to which such indemnified party is entitled to indemnification hereunder without the consent of such indemnified party, unless the settlement thereof imposes no liability or obligation on, and includes a complete and unconditional release from all liability of, the indemnified party.

(d) Contribution. If the indemnification provided for in this Section 2.07 is held by a court or government agency of competent jurisdiction to be unavailable to any indemnified party or is insufficient to hold them harmless in respect of any Losses, then each indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such Loss in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of such indemnified party on the other in connection with the statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations; provided, however, that in no event shall the Selling Holder be required to contribute an aggregate amount in excess of the dollar amount of proceeds (net of Selling Expenses) received by such Selling Holder. The relative fault of the indemnifying party on the one hand and the indemnified party on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact has been made by, or relates to, information supplied by such party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this paragraph were to be determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to herein. The amount paid by an indemnified party as a result of the Losses referred to in the first sentence of this paragraph shall be deemed to include any legal and other expenses reasonably incurred by such indemnified party in connection with investigating or defending any Loss that is the subject of this paragraph. 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 is not guilty of fraudulent misrepresentation.

(e) Other Indemnification. The provisions of this Section 2.07 shall be in addition to any other rights to indemnification or contribution that an indemnified party may have pursuant to law, equity, contract or otherwise.

Section 2.08 Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission that may permit the sale of the Registrable Securities to the public without registration, the Company agrees to use its commercially reasonable efforts to:

(a) make and keep public information regarding the Company available, as those terms are understood and defined in Rule 144 under the Securities Act, at all times from and after the date hereof;

(b) file with the Commission in a timely manner all reports and other documents required of the Company under the Exchange Act at all times from and after the date hereof; and

(c) so long as a Holder owns any Registrable Securities, furnish to such Holder forthwith upon request a copy of the most recent annual or quarterly report of the Company, and such other reports and documents so filed as such Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing such Holder to sell any such securities without registration.

Section 2.09 Transfer or Assignment of Registration Rights. The rights to cause the Company to register Registrable Securities granted to an Initial Holder by the Company under this Agreement may be transferred or assigned by such Initial Holder to one or more transferees or assignees of such Registrable Securities; provided, however, that (a) (i) such transferee or assignee is an Affiliate of such Holder, or (ii) upon such transfer or assignment, such transferee or assignee will hold at least ten percent (10%) of the total issued and outstanding shares of Common Stock, (b) the Company is given written notice prior to any said transfer or assignment, stating the name and address of each such transferee or assignee and identifying the Registrable Securities with respect to which such registration rights are being transferred or assigned, and (c) each such transferee or assignee agrees to be bound by this Agreement.

Section 2.10 Restrictions on Public Sale by Holders of Registrable Securities. Each Holder who, along with its Affiliates, holds at least five percent (5%) of the then-outstanding shares of Common Stock (on an as-converted basis giving effect to the conversion of the Convertible Preferred Stock into Common Stock) agrees to enter into a customary letter agreement with underwriters providing such Holder will not effect any public sale or distribution of the Registrable Securities during the 60 calendar day period beginning on the date of a prospectus or prospectus supplement filed with the Commission with respect to the pricing of an Underwritten Offering, provided that (i) the duration of the foregoing restrictions shall be no longer than the duration of the shortest restriction generally imposed by the underwriters on the Company or the officers, directors or any other shareholder of the Company on whom a restriction is imposed; and (ii) the restrictions set forth in this Section 2.10 shall not apply to any Registrable Securities that are otherwise sold in connection with an Underwritten Offering pursuant to this Agreement.

Section 3.01 Communications. All notices and other communications provided for or permitted hereunder shall be made in writing by electronic mail, courier service or personal delivery:

(b) if to a transferee of the Holders, to such Holder at the address provided pursuant to Section 2.09; and

All such notices and communications shall be deemed to have been received at the time delivered by hand, if personally delivered; when receipt acknowledged, if sent via facsimile or sent via electronic mail; and when actually received, if sent by courier service or any other means.

Section 3.02 Successor and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors and assigns of each of the parties, including subsequent Holders of Registrable Securities to the extent permitted herein.

Section 3.03 Assignment of Rights. All or any portion of the rights and obligations of the Holders under this Agreement may be transferred or assigned by the Holders in accordance with Section 2.09 hereof.

Section 3.04 Recapitalization, Exchanges, Etc.Affecting the Registrable Securities. The provisions of this Agreement shall apply to the full extent set forth herein with respect to any and all securities of the Company or any successor or assign of the Company (whether by merger, consolidation, sale of assets or otherwise) that may be issued in respect of, in exchange for or in substitution of, the Registrable Securities, and shall be appropriately adjusted for combinations, splits, recapitalizations, pro rata distributions and the like occurring after the date of this Agreement.

Section 3.05 Specific Performance. Damages in the event of breach of this Agreement by a party hereto may be difficult, if not impossible, to ascertain, and it is therefore agreed that

each party, in addition to and without limiting any other remedy or right it may have, will have the right to an injunction or other equitable relief in any court of competent jurisdiction, enjoining any such breach, and enforcing specifically the terms and provisions hereof, and each of the parties hereto hereby waives any and all defenses it may have on the ground of lack of jurisdiction or competence of the court to grant such an injunction or other equitable relief. The existence of this right will not preclude any such party from pursuing any other rights and remedies at law or in equity that such party may have.

Re: Securities Purchase Agreement, dated as of May 26, 2017, by and among Lonestar Resources US Inc. (the “Company”) and each of the investors listed on Schedule 1 thereto (each, an “Initial Investor” and collectively, the “Initial Investors”)

In order to induce the Initial Investors to execute the Securities Purchase Agreement, dated as of May 26, 2017 (as the same may be amended, amended and restated or otherwise modified from time to time, the “Securities Purchase Agreement”), the undersigned agrees as follows:

1. The undersigned (the “Stockholder”) represents and warrants to the Company that, as of the date of this letter agreement, it has the sole power to vote or direct the voting of [●] shares of Class A Common Stock (such shares, together with any shares of Class A Common Stock that the Stockholder may acquire (but, for the avoidance of doubt, only to the extent the Stockholder has sole voting power with respect to such shares), and excluding any shares of Class A Common Stock the Stockholder may dispose of, otherwise transfer or with respect to which the Stockholder ceases to have sole power to vote or direct the voting of, in each case, from and after the date hereof, the “Shares”) with respect to the matters and solely in the manner set forth in, and solely to the extent provided in, this letter agreement.

2. Following the Closing, at the Stockholder Meeting called in accordance with Section 3.5 of the Securities Purchase Agreement, or at any adjournment or postponement thereof, or in any other circumstance in which the vote, consent or other approval of the stockholders of the Company is sought in connection with obtaining the Requisite Stockholder Approval, the undersigned shall, with respect to the Shares, (i) appear at each such meeting, in person or by proxy, and (ii) vote (or cause to be voted), or execute and deliver a written consent (or cause a written consent to be executed and delivered) covering, the Shares in favor of adopting the Requisite Stockholder Approval.

(a) The undersigned has full power and authority to make, enter into and carry out the terms of this letter agreement and to perform its obligations hereunder.

(b) This letter agreement has been duly and validly executed and delivered by the undersigned and constitutes a valid and binding agreement of the undersigned, enforceable against the undersigned in accordance with its terms and no other action is necessary to authorize the execution and delivery by the undersigned or the performance of its obligations hereunder.

4. This letter agreement shall be binding upon and inure solely to the benefit of the parties hereto. Nothing contained in this letter agreement, expressed or implied, is intended to confer upon any person other than the parties hereto (and their permitted assigns), any benefits, rights or remedies.

5. This letter agreement shall terminate and shall have no further force or effect as of the date on which the Requisite Stockholder Approval is obtained. For the avoidance of doubt, if the Securities Purchase Agreement is terminated, this letter agreement shall immediately terminate and have no further force or effect except with respect to any breach occurring prior to such termination.

6. Capitalized terms used herein and not otherwise defined herein shall have the meaning ascribed to such terms in the Securities Purchase Agreement.

7. Neither this letter agreement, nor any of the rights, interests or obligations hereunder shall be assigned by any of the parties hereto (whether by operation of law or otherwise) without the prior written consent of the other parties. This letter agreement may not be amended or waived except in writing.

8. This letter agreement may be executed and delivered (including by facsimile transmission) in one or more counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement.

9. The undersigned acknowledges that the Company will be irreparably harmed by and that there will be no adequate remedy at law for a violation by the undersigned hereof. Without limiting other remedies, the Company shall have the right to enforce this letter agreement by specific performance or injunctive relief.

10. This letter agreement shall be governed by and construed in accordance with the laws of the State of Delaware without regard to any choice of laws or conflict of laws provisions that would require the application of the laws of any other jurisdiction. The parties hereto hereby irrevocably and unconditionally consent to submit to the exclusive jurisdiction of Delaware Court of Chancery and any state appellate court therefrom within the State of Delaware (or, if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, any state or federal court within the State of Texas) for any actions, suits or proceedings arising out of or relating to this letter agreement and the transactions contemplated hereby.
