volume weighted average of their closing market prices for the five (5) trading days ending the day prior to the date of payment to, or receipt by, Aspire or its relevant Affiliate, and (B) the value of securities that have no established
public market and the value of consideration that consists of other non-cash property, shall be the fair market value thereof as of the date of payment to, or receipt by, Aspire or its relevant Affiliate.
Notwithstanding the generality of the foregoing, for purposes of this Agreement, no Subsidiary of Aspire contemplated by clause (b)(ii) above shall be considered an Affiliate of Aspire.

its performance of any agreement in connection with any Potentially Transferable Asset, including any costs related to the prosecution, maintenance or enforcement by Aspire or any of its Subsidiaries of intellectual property rights (but excluding
any costs related to a breach of this Agreement, including costs incurred in litigation in respect of the same); 


  

	 	(e)	 any reasonable and documented

 ARTICLE 2 

CONTINGENT VALUE RIGHTS 

Section 2.1 Holders of CVRs; Appointment of Rights Agent. 

(a) As provided in the Merger Agreement, effective as of the Closing, each Holder will be entitled to one CVR for each Share that is validly
accepted for payment, and paid for, pursuant to Section 1.8(c) of the Merger Agreement. 
 (b) Aspire hereby appoints the Rights Agent
to act as rights agent for Aspire 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. 
 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 Parent Common Stock held immediately prior
to Closing. Except as expressly provided herein with respect to the Rights of the Rights Agent, neither Aspire nor its Subsidiaries will have any responsibility or liability whatsoever to any person other than the Holders. 

(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, as applicable, 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 Aspire, evidencing the same right, and entitling the transferee to the same
benefits and rights under this Agreement, as those held by the transferor. Aspire and the Rights Agent may each require payment of a sum sufficient to cover any stamp or other transfer tax or governmental charge that is imposed in connection with
(and would not have been imposed but for) any such registration of transfer. 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. 

  
 7 













 (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 fiscal quarter of Aspire following the first anniversary of the Closing,
Aspire shall (i) deliver to the Rights Agent, a certificate (each, a “CVR Certificate”) certifying for such fiscal quarter the aggregate amount of (A) the CVR Proceeds received by Aspire 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 fiscal 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 CVR Payment (if any) by wire transfer of immediately available funds to an account designated by the Rights
Agent. Upon receipt of the wire transfer referring to in the foregoing sentence, the Rights Agent shall promptly (and in any event, within ten (10) Business Days) pay, by check mailed, first-class postage prepaid, to the address each Holder set
forth in the CVR Register at such time or by other method of deliver as specified by the applicable Holder in writing to the Rights Agent, an amount equal to the product determined by multiplying (i) the quotient determined by dividing
(A) the applicable 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 Aspire 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 Aspire’s obligations set forth in this
Section 2.4(a). 
 (b) Except to the extent otherwise required pursuant to a change in applicable Law after the
date hereof, the parties hereto agree to treat the issuance of the CVRs as not constituting a current distribution and all CVR Payments for all Tax purposes as distributions of money governed by Section 301 of the U.S. Internal Revenue Code of
1986, as amended (the “Code”), which will constitute a dividend to the extent payable out of Aspire and its Affiliates’ “earnings and profits” (pursuant to Section 316 of the Code) in the taxable year when
the CVR Payment is made. 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 applicable Law after the date hereof. 

(c) Aspire 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. Prior to making any such Tax deductions or withholdings


  
 8 













 
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 applicable fiscal quarter end
(including by means of uncashed checks or invalid addresses on the CVR Register) will be delivered by the Rights Agent to Aspire or a person nominated in writing by Aspire (with written notice thereof from Aspire to the Rights Agent), and any Holder
will thereafter look only to Aspire for payment of such CVR Payment (which shall be without interest). 
 (e) If any CVR Payment (or portion
thereof) remains unclaimed by a Holder two (2) years after the applicable fiscal quarter end (or immediately prior to such earlier date on which such CVR Payment would otherwise escheat to or become the property of any Governmental Authority),
such CVR Payment (or portion thereof) will, to the extent permitted by applicable Law, become the property of Aspire and will be transferred to Aspire or a person nominated in writing by Aspire (with written notice thereof from Aspire to the Rights
Agent), free and clear of all claims or interest of any Person previously entitled thereto, and no consideration or compensation shall be payable therefor. Neither Aspire nor the Rights Agent will be liable to any Person in respect of a CVR Payment
delivered to a public official pursuant to any applicable abandoned property, escheat or similar legal requirement under applicable Law. In addition to and not in limitation of any other indemnity obligation herein, Aspire agrees to indemnify and
hold harmless the Rights Agent with respect to any liability, penalty, cost or expense the Rights Agent may incur or be subject to in connection with transferring such property to Aspire, a public office or a person nominated in writing by Aspire.

 Section 2.5 No Voting, Dividends or Interest; No Equity or Ownership 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 interest in Aspire 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 Aspire or any of its
Subsidiaries or of the Surviving Corporation. 
 (c) It is hereby acknowledged and agreed that the CVRs and the possibility of any payment
hereunder with respect thereto are highly speculative and subject to numerous factors outside of Aspire’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 

  
 9 













 
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
Amount. It is further acknowledged and agreed that neither Aspire 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(c) 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 Aspire or a person nominated in writing by Aspire (with written notice thereof from Aspire 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 Aspire of such transfer and cancellation. Nothing in this Agreement is intended to prohibit Aspire 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 Aspire 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 Aspire 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. 

  
 10 













 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
Aspire 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 Aspire. 
 (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 Aspire 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) Aspire 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), Aspire 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 Aspire 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 

  
 11 













 
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 Aspire 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 Aspire 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.
