 SECTION 2 CONTINGENT VALUE RIGHTS 

2.1 CVRs; Appointment of Rights Agent.  

(a) As provided in the Merger Agreement, each Holder shall be entitled to one CVR for each share of Company Common Stock outstanding or
underlying each Option and share of Restricted Stock that is owned by or has been issued to such Holder as of immediately prior to the Effective Time and is converted into the right to receive the Merger Consideration pursuant to the Merger
Agreement. 
 (b) Parent hereby appoints the Rights Agent to act as rights agent for Parent in accordance with the terms and
conditions set forth in this Agreement, and the Rights Agent hereby accepts such appointment. 
 2.2 Nontransferable. The CVRs shall
not be sold, assigned, transferred, pledged, encumbered or in any other manner transferred or disposed of, in whole or in part, other than pursuant to a Permitted Transfer. 

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

(a) The CVRs shall not be evidenced by a certificate or other instrument. 

(b) The Rights Agent shall keep a register (the “CVR Register”) for the purposes of (i) identifying the Holders
of CVRs and (ii) registering CVRs and Permitted Transfers thereof. 
 (c) Subject to the restrictions on transferability set
forth in Section 2.2, every request made to transfer a CVR must be in writing and accompanied by a written instrument of transfer and other requested documentation in form reasonably satisfactory to the Rights Agent, duly executed 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 shall, subject to its reasonable determination that the transfer instrument is in proper form and the 

  
 4 








 
transfer otherwise complies with the other terms and conditions of this Agreement (including the provisions of Section 2.2), register the transfer of the applicable CVRs in the CVR Register.
All duly transferred CVRs registered in the CVR Register shall be the valid obligations of Parent, evidencing the same right, and shall entitle the transferee to the same benefits and rights under this Agreement, as those held by the transferor. No
transfer of a CVR shall be valid until registered in the CVR Register, and any transfer not duly registered in the CVR Register will be void ab initio. Any transfer or assignment of the CVRs shall be without charge (other than the cost of any
transfer tax) to the applicable Holder. 
 (d) A Holder may make a written request to the Rights Agent to change such Holder’s
address of record in the CVR Register. The written request must be duly executed by the Holder. Upon receipt of such written notice, the Rights Agent shall promptly record the change of address in the CVR Register. 

2.4 Payment Procedures. 

(a) If a Milestone occurs, then on a date (the “Milestone Payment Date”) that is within 10 Business Days following such
event, Parent shall deliver to the Rights Agent (i) a notice (the “Milestone Satisfaction Notice”) which shall be in the form of an Officer’s Certificate stating the date of the satisfaction of such Milestone and that the
Holders are entitled to receive the applicable Milestone Payment and (ii) cash in the aggregate amount of the Milestone Payment payable to the Holders. In no event shall payment be made with respect to more than a single Milestone. 

(b) The Rights Agent shall promptly, and in no event later than 10 Business Days after receipt, pursuant to Section 2.4(a), of the
Milestone Satisfaction Notice and cash in the aggregate amount of the Milestone Payment payable to the Holders, (i) send each Holder at its address set forth in the CVR Register a copy of the Milestone Satisfaction Notice and (ii) pay the
Milestone Payment to each of the Holders (the amount which each Holder is entitled to receive, subject to Section 2.4(c), will be based on the applicable Milestone Payment multiplied by the number of CVRs held by such Holder at the time of such
payment as reflected on the CVR Register) by check mailed to the address of each Holder as set forth in the CVR Register as of the close of business on the first Business Day prior to the Milestone Payment Date. 

(c) Except to the extent any portion of the Milestone Payment is required to be treated as imputed interest pursuant to applicable Law,
the Holders and the parties hereto agree to treat the CVRs and the Milestone Payment for all Tax purposes as additional consideration for the shares of Common Stock, Options and shares of Restricted Stock pursuant to the Merger Agreement, and none
of the Holders and the parties hereto will take any position to the contrary on any Tax Return or for other Tax purposes except as required by applicable Law. Parent and the Company shall report imputed interest on the CVRs pursuant to
Section 483 of the Code. 
 (d) Parent shall be entitled to deduct and withhold, or cause to be deducted and withheld, from the
Milestone 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 

  
 5 








 
deducted and withheld and paid over to or deposited with the relevant Governmental Authority, such withheld amounts shall 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 withholdings or causing any such tax withholdings to be made with respect to any Holder, the Rights Agent shall, to the extent practicable, provide
notice to the Holder of such potential withholding and a reasonable opportunity for the Holder to provide any necessary tax forms (including an IRS Form W-9 or an applicable IRS Form W-8) in order to avoid or reduce such withholding amounts;
provided that the time period for payment of a Milestone Payment by the Rights Agent set forth in Section 2.4(b) shall be extended by a period equal to any delay caused by the Holder providing such forms. 

(e) Any portion of the Milestone Payment that remains undistributed to the Holders for six months after the Milestone Payment Date
shall be delivered by the Rights Agent to Parent, upon demand, and any Holder shall thereafter look only to Parent for payment of such Milestone Payment, but shall have no greater rights against Parent than may be accorded to general unsecured
creditors of Parent under applicable Law. 
 (f) Neither Parent nor the Rights Agent shall be liable to any Person in respect of a
Milestone Payment delivered to a public official pursuant to any applicable abandoned property, escheat or similar legal requirement under applicable Law. If the Milestone Payment (or portion thereof) made by Parent remains unclaimed by a Holder two
years after the applicable Milestone Payment Date (or immediately prior to such earlier date on which the Milestone Payment would otherwise escheat to or become the property of any Governmental Authority), any such Milestone Payment (or portion
thereof) shall, to the extent permitted by applicable Law, become the property of Parent, free and clear of all claims or interest of any Person previously entitled thereto. 

2.5 No Voting, Dividends or Interest; No Equity or Ownership Interest in Parent.  

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

 (b) The CVRs shall not represent any equity or ownership interest in Parent, in any constituent company to the Merger or any of
their respective Affiliates. 
 2.6 Ability To Abandon The CVR. The Holder of a CVR may at any time, at such Holder’s option,
abandon all of such Holder’s remaining rights in a CVR by transferring such CVR to Parent without consideration therefor. Nothing in this Agreement is intended to prohibit Parent from offering to acquire CVRs for consideration in its sole
discretion. 
 SECTION 3 THE RIGHTS AGENT 

3.1 Certain Duties And Responsibilities.

the termination of this Agreement. 

  
 7
