ARTICLE 2 
 CONTINGENT
VALUE RIGHTS 
 Section 2.1 Holders of CVRs; Appointment of Rights Agent. 

(a) The CVRs shall be issued and distributed by Gem in the form of a dividend, in connection with the Merger, to the Persons who as of
immediately prior to the Effective Time are stockholders of record of Gem or have the right to receive Gem Common Stock as of immediately prior to the Effective Time, as contemplated by the Merger Agreement. 

(b) Gem hereby appoints the Rights Agent to act as rights agent for Gem in accordance with the express terms and conditions set forth in this
Agreement, and the Rights Agent hereby accepts such appointment. 
 Section 2.2
Non-transferable. 
 A Holder may not at any time Transfer CVRs, other than pursuant to a
Permitted Transfer. Any attempted Transfer that is not a Permitted Transfer, in whole or in part, will be void ab initio and of no effect. The CVRs will not be listed on any quotation system or traded on any securities exchange.

 Section 2.3 No Certificate; Registration; Registration of Transfer; Change of Address. 

(a) Holders’ rights and obligations in respect of CVRs derive solely from this Agreement; CVRs will not be evidenced by a certificate or
other instrument. 











 (b) The Rights Agent will maintain an up-to-date register (the “CVR Register”) for the purposes of (i) identifying the Holders of CVRs, (ii) determining Holders’ entitlement to CVRs and
(iii) registering the CVRs and Permitted Transfers thereof. The CVR Register will initially show one position for the Rights Agent representing all of the CVRs provided to the holders of shares of Gem Common Stock held immediately prior to
Closing. Gem and the Rights Agent may require evidence of payment of a sum sufficient to cover any stamp, documentary, registration, or other tax or governmental charge that is imposed in connection with (and would not have been imposed in
connection with (and would have been imposed but for)) any such registration of transfer (or evidence that such taxes and charges are not applicable). 

(c) Subject to the restriction on transferability set forth in Section 2.2, every request made to Transfer CVRs
must be in writing and accompanied by a written instrument of Transfer reasonably acceptable to the Rights Agent, together with the signature guarantee of a guarantor institution which is a participant in a signature guarantee program approved by
the Securities Transfer Association (a “signature guarantee”) and other requested documentation in a form reasonably satisfactory to the Rights Agent, duly executed and properly completed, by the Holder or Holders thereof, or by the duly
appointed legal representative, personal representative or survivor of such Holder or Holders, setting forth in reasonable detail the circumstances relating to the Transfer. Upon receipt of such written notice, the Rights Agent will, subject to its
reasonable determination in accordance with its own internal procedures, that the Transfer instrument is in proper form and the Transfer, is a Permitted Transfer and otherwise complies on its face with the other terms and conditions of this
Agreement, register the Transfer of the applicable CVRs in the CVR Register. All Transfers of CVRs registered in the CVR Register will be the valid obligations of Gem, evidencing the same right, and entitling the transferee to the same benefits and
rights under this Agreement, as those held by the transferor. No transfer of CVRs shall be valid until registered in the CVR Register and any transfer not duly registered in the CVR Register shall be void. Gem shall not be responsible for any costs
and expenses related to any transfer or assignment of the CVRs (including the cost of any transfer tax). 
 (d) A Holder may make a written
request to the Rights Agent to change such Holder’s address of record in the CVR Register. Such written request must be duly executed by such Holder. Upon receipt of such written notice, the Rights Agent shall promptly record the change of
address in the CVR Register. 
 Section 2.4 Payment Procedures. 

(a) No later than forty-five (45) days following the end of each Calendar Quarter following the Closing, Gem shall (i) deliver to the
Rights Agent, a certificate (each, a “CVR Certificate”) certifying to and specifying in reasonable detail, for such Calendar Quarter, the aggregate amount of (A) the CVR Proceeds received by Gem or its Affiliates during such
fiscal quarter (or, in the case of the first delivery of a CVR Certificate hereunder, all CVR Proceeds received through the end of such Calendar Quarter); (B) the Permitted Deductions reflected in such CVR Proceeds; and (C) the CVR Payment
payable to Holders, if any, in respect of such CVR Proceeds and (ii) deliver to the Rights Agent, or as the Rights Agent directs, the aggregate CVR Payment (if any). With respect to each Holder, the Rights Agent shall deliver, or cause to be
delivered, a number of shares equal to the product determined by multiplying (i) the quotient determined by dividing (A) the number of shares representing the aggregate CVR Payment by (B) the total number of CVRs registered in the CVR
Register at such time, by 











 
(ii) the number of CVRs registered to such Holder in the CVR Register at such time. For the avoidance of doubt Gem shall have no further liability in respect of the relevant CVR Payment upon
delivery of such CVR Payment in accordance with this Section 2.4(a) and the satisfaction of each of Gem’s obligations set forth in this Section 2.4(a). 

(b) The parties hereto agree to treat the distribution of the CVRs as constituting a nontaxable stock distribution under Section 305 of
the U.S. Internal Revenue Code of 1986, as amended (the “Code”) and the receipt of CVR Payments as a nontaxable exercise of the right to receive stock under the CVRs. The parties hereto will not take any position to the
contrary on any Tax Return or for other Tax purposes except as required by a change in or clarification to applicable Law after the date hereof. 

(c) Gem and the Rights Agent will be entitled to deduct and withhold, or cause to be deducted and withheld, from any CVR Payment otherwise
payable pursuant to this Agreement, such amounts as it is required to deduct and withhold with respect to the making of such payment under any provision of applicable Law relating to Taxes. To the extent that amounts are so deducted and withheld,
such deducted and withheld amounts will be treated for all purposes of this Agreement as having been paid to the Holder in respect of which such deduction and withholding was made. The Rights Agent shall request from each Holder an IRS Form W-9 or applicable IRS Form W-8 at such time or times as is necessary to permit any payment under this Agreement to be made without U.S. federal backup withholding. Prior to
making any such Tax deductions or withholdings or causing any such Tax deductions or withholdings to be made with respect to any Holder, the Rights Agent will, to the extent reasonably practicable, provide notice to the Holder of such potential Tax
deduction or withholding and a reasonable opportunity for the Holder to provide any necessary Tax forms in order to avoid or reduce such withholding amounts; provided that the time period for payment of a CVR Payment by the
Rights Agent set forth in Section 2.4(a) will be extended by a period equal to any delay caused by the Holder providing such forms, provided, further, that in no event shall
such period be extended for more than ten (10) Business Days, unless otherwise requested by the Holder for the purpose of delivering such forms and agreed to by the Rights Agent. 

(d) Any portion of a CVR Payment that remains undistributed to the Holders six (6) months after the end of the applicable Calendar Quarter
(including by means of invalid addresses on the CVR Register) will be delivered by the Rights Agent to Gem or a person nominated in writing by Gem (with written notice thereof from Gem to the Rights Agent), and any Holder will thereafter look only
to Gem for payment of such CVR Payment (which shall be without interest). 
 Section 2.5 No Voting, Dividends or Interest. 

(a) CVRs will not have any voting or dividend rights, and interest will not accrue on any amounts payable in respect of CVRs. 

(b) CVRs will not represent any equity or ownership interests in Gem or any of its Subsidiaries or in the Surviving Corporation. The sole right
of the Holders to receive property hereunder is the right to receive CVR Payments, if any, in accordance with the terms hereof. It is hereby acknowledged and agreed that a CVR shall not constitute a security of Gem or any of its Subsidiaries or of
the Surviving Corporation. 











 (c) By voting in favor of the adoption of the Merger Agreement, the approval of the
principal terms of the Merger, and the consummation of the Merger or participating in the Merger and receiving the benefits thereof, including the right to receive CVRs and any consideration payable in connection with the CVRs, each Holder hereby
acknowledges and agrees that the CVRs and the possibility of any payment hereunder with respect thereto are highly speculative and subject to numerous factors outside of Gem’s control, and there is no assurance that Holders will receive any
payments under this Agreement or in connection with the CVRs. Each Holder acknowledges that it is highly possible that no Disposition will occur prior to the expiration of the Disposition Period and that there will not be any Gross Proceeds that may
be the subject of a CVR Payment. It is further acknowledged and agreed that neither Gem nor its Affiliates owe, by virtue of their obligations under this Agreement, a fiduciary duty or any implied duties to the Holders and the parties hereto intend
solely the express provisions of this Agreement to govern their contractual relationship with respect to the CVRs. It is acknowledged and agreed that this Section 2.5(b) is an essential and material term of this
Agreement. 
 Section 2.6 Ability to Abandon CVR. 

A Holder may at any time, at such Holder’s option, abandon all of such Holder’s remaining rights represented by CVRs by transferring
such CVR to Gem or a person nominated in writing by Gem (with written notice thereof from Gem to the Rights Agent) without consideration in compensation therefor, and such rights will be cancelled, with the Rights Agent being promptly notified in
writing by Gem of such transfer and cancellation. Nothing in this Agreement is intended to prohibit Gem or its Affiliates from offering to acquire or acquiring CVRs, in private transactions or otherwise, for consideration in its sole discretion.

 ARTICLE 3 
 THE
RIGHTS AGENT 
 Section 3.1 Certain Duties and Responsibilities. 

(a) The Rights Agent will not have any liability for any actions taken or not taken in connection with this Agreement, except to the extent
such liability arises as a result of the willful misconduct, bad faith or gross negligence of the Rights Agent (in each case as determined by a final non-appealable judgment of court of competent
jurisdiction). Notwithstanding anything in this Agreement to the contrary, any liability of the Rights Agent under this Agreement will be limited to the amount of annual fees paid by Gem to the Rights Agent during the twelve (12) months
immediately preceding the event for which recovery from the Rights Agent is being sought. Anything to the contrary notwithstanding, in no event will the Rights Agent be liable for special, punitive, indirect, incidental or consequential loss or
damages of any kind whatsoever (including, without limitation, lost profits), even if the Rights Agent has been advised of the likelihood of such loss or damages, and regardless of the form of action. 











 (b) The Rights Agent shall not have any duty or responsibility in the case of the receipt of
any written demand from any Holder with respect to any action or default by any person or entity, including, without limiting the generality of the foregoing, any duty or responsibility to initiate or attempt to initiate any proceedings at law or
otherwise or to make any demand upon Gem or the Company. The Rights Agent may (but shall not be required to) enforce all rights of action under this Agreement and any related claim, action, suit, audit, investigation or proceeding instituted by the
Rights Agent may be brought in its name as the Rights Agent and any recovery in connection therewith will be for the proportionate benefit of all the Holders, as their respective rights or interests may appear on the CVR Register. 

Section 3.2 Certain Rights of Rights Agent. 

(a) The Rights Agent undertakes to perform such duties and only such duties as are specifically set forth in this Agreement, and no implied
covenants or obligations will be read into this Agreement against the Rights Agent. 
 (b) The Rights Agent may rely and will be protected by
Gem in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order or other paper or document believed by it in the absence of bad faith to be genuine and to
have been signed or presented by or on behalf of Gem. 
 (c) Whenever the Rights Agent deems it desirable that a matter be proved or
established prior to taking or omitting any action hereunder, the Rights Agent may (i) rely upon an Officer’s Certificate and (ii) incur no liability and be held harmless by Gem for or in respect of any action taken or omitted to be
taken by it under the provisions of this Agreement in reliance upon such Officer’s Certificate. 
 (d) The Rights Agent may engage and
consult with counsel of its selection, and the advice or opinion of such counsel will, in the absence of bad faith, gross negligence or willful misconduct (in each case, as determined by a
final, non-appealable judgment of a court of competent jurisdiction) on the part of the Rights Agent, be full and complete authorization and protection in respect of any action taken or not taken by
the Rights Agent in reliance thereon. 
 (e) Any permissive rights of the Rights Agent hereunder will not be construed as a duty. 

(f) The Rights Agent will not be required to give any note or surety in respect of the execution of its powers or otherwise under this
Agreement. 
 (g) Gem agrees to indemnify the Rights Agent for, and to hold the Rights Agent harmless from and against, any loss, liability,
damage, judgment, fine, penalty, cost or expense (each, a “Loss”) suffered or incurred by the Rights Agent and arising out of or in connection with the Rights Agent’s performance of its obligations under this Agreement,
including the reasonable and documented costs and expenses of defending the Rights Agent against any claims, charges, demands, actions or suits arising out of or in connection in connection with the execution, acceptance, administration, exercise
and performance of its duties 











 
under this Agreement, including the costs and expenses of defending against any claim of liability arising therefrom, directly or indirectly, or enforcing its rights hereunder, except to the
extent such Loss has been determined by a final non-appealable decision of a court of competent jurisdiction to have resulted from the Rights Agent’s gross negligence, bad faith or willful
misconduct. 
 (h) In addition to the indemnification provided under Section 3.2(g), Gem agrees (i) to
pay the fees of the Rights Agent in connection with the Rights Agent’s performance of its obligations hereunder, as agreed upon in writing by the Rights Agent and Gem on or prior to the date of this Agreement, and (ii) to reimburse the
Rights Agent for all reasonable and documented out-of-pocket expenses and other disbursements incurred in the preparation, delivery, negotiation, amendment,
administration and execution of this Agreement and the exercise and performance of its duties hereunder, including all Taxes (other than income, receipt, franchise or similar Taxes) and governmental charges, incurred by the Rights Agent in the
performance of its obligations under this Agreement, except that Gem will have no obligation to pay the fees of the Rights Agent or reimburse the Rights Agent for the fees of counsel in connection with any lawsuit initiated by the Rights Agent on
behalf of itself or the Holders, except in the case of any suit enforcing the provisions of Section 2.4(a), Section 2.4(b) or Section 3.2(g), if
Gem is found by a court of competent jurisdiction to be liable to the Rights Agent or the Holders, as applicable in such suit. 
 (i) No
provision of this Agreement shall require the Rights Agent to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers if it believes
that repayment of such funds or adequate indemnification against such risk or liability is not reasonably assured to it. 
 (j) The Rights
Agent will not be deemed to have knowledge of any event of which it was supposed to receive notice hereunder but has not received written notice of such event, and the Rights Agent will not incur any liability for failing to take action in
connection therewith, in each case, unless and until it has received such notice in writing. 
 (k) The Rights Agent may execute and exercise
any of the rights or powers hereby vested in it or perform any duty hereunder either itself or by or through its attorney or agents and the Rights Agent shall not be answerable or accountable for any act, default, neglect or misconduct of any such
attorney or agents or for any loss to Gem or the Company resulting from any such act, default, neglect or misconduct, absent gross negligence, bad faith or willful misconduct (each as determined by a
final non-appealable judgment of a court of competent jurisdiction) in the selection and continued employment thereof. 

(l) Gem shall perform, acknowledge and deliver or cause to be performed, acknowledged and delivered all such further and other acts, documents,
instruments and assurances as may be reasonably required by the Rights Agent for the carrying out or performing by the Rights Agent of the provisions of this Agreement. 











 (m) The Rights Agent shall not be liable for or by reason of any of the statements of fact
or recitals contained in this Agreement (except its countersignature thereof) or be required to verify the same, and all such statements and recitals are and shall be deemed to have been made by Gem only. 

(n) The Rights Agent shall act hereunder solely as agent for Gem and shall not assume any obligations or relationship of agency or trust with
any of the owners or holders of the CVRs. The Rights Agent shall not have any duty or responsibility in the case of the receipt of any written demand from any Holders with respect to any action or default by Gem, including, without limiting the
generality of the foregoing, any duty or responsibility to initiate or attempt to initiate any proceedings at law or otherwise or to make any demand upon Gem. 

(o) The Rights Agent may rely on and be fully authorized and protected in acting or failing to act upon (a) any guaranty of signature by
an “eligible guarantor institution” that is a member or participant in the Securities Transfer Agents Medallion Program or other comparable “signature guarantee program” or insurance program in addition to, or in substitution
for, the foregoing; or (b) any law, act, regulation or any interpretation of the same even though such law, act, or regulation may thereafter have been altered, changed, amended or repealed. 

(p) The Rights Agent shall not be liable or responsible for any failure of Gem to comply with any of its obligations relating to any
registration statement filed with the Securities and Exchange Commission or this Agreement, including without limitation obligations under applicable regulation or law. 

(q) The obligations of Gem and the rights of the Rights Agent under
this Section 3.2, Section 3.1 and Section 2.4 shall survive the expiration of the CVRs and the termination of this Agreement and the resignation,
replacement or removal of the Rights Agent. 
 Section 3.3 Resignation and Removal; Appointment of Successor. 

(a) The Rights Agent may resign at any time by written notice to Gem. Any such resignation notice shall specify the date on which such
resignation will take effect (which shall be at least thirty (30) days following the date that such resignation notice is delivered), and such resignation will be effective on the earlier of (x) the date so specified and (y) the
appointment of a successor Rights Agent. 
 (b) Gem will have the right to remove the Rights Agent at any time by written notice to the
Rights Agent, specifying the date on which such removal will take effect. Such notice will be given at least thirty (30) days prior to the date so specified (or, if earlier, the appointment of the successor Rights Agent). 

(c) If the Rights Agent resigns, is removed or becomes incapable of acting, Gem will promptly appoint a qualified successor Rights Agent.
Notwithstanding the foregoing, if Gem fails to make such appointment within a period of thirty (30) days after giving notice of such removal or after it has been notified in writing of such resignation or incapacity by the resigning or
incapacitated Rights Agent, then the incumbent Rights Agent may apply to any court of competent jurisdiction for the appointment of a new Rights Agent. The successor Rights Agent so appointed will, upon its acceptance of such appointment in
accordance with this Section 3.3(c) and Section 3.4, become the Rights Agent for all purposes hereunder. 











 (d) Gem will give notice to the Holders of each resignation or removal of the Rights Agent
and each appointment of a successor Rights Agent in accordance with Section 7.2. Each notice will include the name and address of the successor Rights Agent. If Gem fails to send such notice within ten
(10) Business Days after acceptance of appointment by a successor Rights Agent, the successor Rights Agent will cause the notice to be mailed at the expense of Gem. 

(e) Notwithstanding anything to the contrary in this Section 3.3, unless consented to in writing by the Acting
Holders, Gem will not appoint as a successor Rights Agent any Person that is not a stock transfer agent of national reputation or the corporate trust department of a commercial bank. 

(f) The Rights Agent will reasonably cooperate with Gem and any successor Rights Agent in connection with the transition of the duties and
responsibilities of the Rights Agent to the successor Rights Agent, including the transfer of all relevant data, including the CVR Register, to the successor Rights Agent, but such predecessor Rights Agent shall not be required to make any
additional expenditure or assume any additional liability in connection with the foregoing. 
 Section 3.4 Acceptance of Appointment
by Successor. 
 Every successor Rights Agent appointed hereunder will, at or prior to such appointment, execute, acknowledge and
deliver to Gem and to the resigning or removed Rights Agent an instrument accepting such appointment and a counterpart of this Agreement, and such successor Rights Agent, without any further act, deed or conveyance, will become vested with all the
rights, powers, trusts and duties of the Rights Agent; provided that upon the request of Gem or the successor Rights Agent, such resigning or removed Rights Agent will execute and deliver an instrument transferring to such
successor Rights Agent all the rights, powers and trusts of such resigning or removed Rights Agent.

Gem to negotiate, execute and deliver a definitive written agreement with respect to a Disposition (a “Sale Agreement”) in the name and on behalf of Gem, as well as to identify and retain advisers and consultants. 

(b) The delegation of responsibility and authority to the Special Committee set forth in Section 4.2(a) shall not be revoked or modified

behalf other than the Special Committee. The Special Committee has the sole power and authority to act on behalf of the Holders in enforcing any of their rights hereunder.

including the negotiation and execution of a Sale Agreement and completion of the transactions contemplated thereby. Further, Gem will not take any actions for the primary purpose of frustrating the payment of CVR Proceeds. 

(e) Subject to the foregoing clause (d), (i) the Holders acknowledge that Gem has a fiduciary obligation to operate its business in the best
interests of its stockholders, and any potential obligation to pay CVR Proceeds will not create any express or implied obligation to operate its business in any particular manner in order to maximize such CVR Proceeds, (ii) except as expressly
set forth in this Agreement, the Holders are not relying on any representation of Gem or any other Person with regard to any Disposition or other action involving the Potentially Transferrable Assets following the Closing, and neither Gem nor any
other Person has provided, or can provide, any assurance to the Holders that any CVR Proceeds will in fact be earned and paid, and (iii) none of Gem or any of its Subsidiaries, officers or directors shall have any obligation or liability

by the Acting Holders (the “Accountant”) of a reasonable and customary confidentiality/nonuse agreement, which confidentiality/nonuse agreement shall not prohibit the Acting Holders from communicating any such information with the
Holders who have a need to know such information, provided that any such recipients are subject to confidentiality obligations with respect thereto, Gem shall permit the Acting Holders and the Accountant, acting as agent of the Acting Holders, to
have access during normal business hours to the books and records of Gem as may be reasonably necessary to audit the calculation of the CVR Payment and the Permitted Deductions. Notwithstanding anything in this Agreement to the contrary, in no event
