ARTICLE 2

CONTINGENT VALUE RIGHTS

Section 2.1 Holders of CVRs; Appointment of Rights Agent.

(a) The CVRs represent the rights of Holders to receive CVR Cash Payments or CVR
Share Payments pursuant to this Agreement. The initial Holders will be the
holders of Common Stock as of immediately prior to the Effective Time. One CVR
will be issued with respect to each share of Common Stock that is outstanding as
of immediately prior to the Effective Time (including, for the avoidance of
doubt, those shares of Common Stock issued upon settlement of Utah Restricted
Stock Units pursuant to Section 6.7 of the Merger Agreement).

(b) the Company hereby appoints the Rights Agent to act as Rights Agent for the
Company 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.

The CVRs may not be sold, assigned, transferred, pledged, encumbered or in any
other manner transferred or disposed of, in whole or in part, other than through
a Permitted Transfer. 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) The CVRs will be issued in book-entry form only and will not be evidenced by
a certificate or other instrument.

(b) The Rights Agent shall create and maintain a register (the “CVR Register”)
for the purpose of registering CVRs and Permitted Transfers. The CVR Register
will be created, and CVRs will be distributed, pursuant to written instructions
to the Rights Agent from the Company. The CVR Register will initially show one
position for Cede & Co. representing shares of Common Stock held by DTC on
behalf of the street holders of the shares of Common Stock held by such holders
as of immediately prior to the Effective Time. The Rights Agent will have no
responsibility whatsoever directly or indirectly to the street name holders with
respect to transfers of CVRs. With respect to any payments or issuances to be
made

 

5

--------------------------------------------------------------------------------

under Section 2.4 below, the Rights Agent will accomplish the payment to any
former street name holders of shares Common Stock by sending one lump-sum
payment or issuance to DTC. The Rights Agent will have no responsibilities
whatsoever with regard to the distribution of payments or shares of Common Stock
by DTC to such street name holders.

(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 in form reasonably satisfactory to the Rights
Agent pursuant to its guidelines or procedures, including a guaranty of
signature by an “eligible guarantor institution” that is a member or participant
in the Securities Transfer Agents Medallion Program, duly executed and properly
completed by the Holder thereof, the Holder’s attorney duly authorized in
writing, the Holder’s personal representative or the Holder’s survivor, and
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
transfer otherwise complies with the other terms and conditions of this
Agreement (including the provisions of Section 2.2), register the transfer of
the CVRs in the CVR Register. The Company and 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 any such
registration of transfer (or evidence that such Taxes and charges are not
applicable). The Rights Agent shall have no duty or obligation to take any
action under any section of this Agreement that requires the payment by a Holder
of a CVR of applicable taxes or charges unless and until the Rights Agent is
satisfied that all such taxes or charges have been paid. All duly transferred
CVRs registered in the CVR Register will be the valid obligations of the Company
and will entitle the transferee to the same benefits and rights under this
Agreement as those held immediately prior to the transfer by the transferor. No
transfer of a CVR will be valid until registered in the CVR Register.

(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, subject to its reasonable determination that the transfer instrument is
in proper form, promptly record the change of address in the CVR Register. The
Acting Holders may, without duplication, make a written request to the Rights
Agent for a list containing the names, addresses and number of CVRs of the
Holders that are registered in the CVR Register. Upon receipt of such written
request from the Acting Holders, the Rights Agent shall promptly deliver a copy
of such list to the Acting Holders.

(e) The Company will provide written instructions to the Rights Agent for the
distribution of CVRs to holders of Common Stock as of immediately prior to the
Effective Time (the “Record Time”). Subject to the terms and conditions of this
Agreement and the Company’s prompt confirmation of the Effective Time, the
Rights Agent shall effect the distribution of the CVRs, less any applicable tax
withholding, to each holder of Common Stock as of the Record Time by the mailing
of a statement of holding reflecting such CVRs.

--------------------------------------------------------------------------------

Section 2.4 Payment Procedures.

(a) No later than forty-five (45) days following the end of each Calendar
Quarter that ends on or prior to December 31, 2020, commencing with the first
CVR Payment Period in which the Company or its Affiliates receives Gross
Proceeds, the Company shall deliver to the Rights Agent a CVR Payment Statement
for such CVR Payment Period. Concurrent with the delivery of each CVR Payment
Statement, on the terms and conditions of this Agreement, the Company will make
appropriate arrangements with the Rights Agent for shares of Common Stock
represented by book-entry shares to be issued as the CVR Share Payment. Upon
receipt of the book-entry shares referred to in the foregoing sentence, the
Rights Agent shall promptly (and in any event, within ten (10) Business Days)
distribute to each Holder by book-entry an amount of shares of Common Stock
equal to such Holder’s CVR Payment Amount; provided that to the extent the
foregoing would result in a Holder receiving a fractional share of Common Stock,
such Holder shall forfeit such fractional share. The Rights Agent shall
promptly, and in any event within ten (10) Business Days after receipt of a CVR
Payment Statement under this Section 2.4(a), send each Holder at its registered
address a copy of such statement. Without limiting any of the rights of the
Rights Agent under the Agreement, for the avoidance of doubt, except as set
forth in Section 4.5, the Company shall have no further liability in respect of
the relevant CVR Share Payment upon delivery instructions to the Rights Agents
of such CVR Share Payment in accordance with this Section 2.4(a) and the
satisfaction of each of the Company obligations set forth in this
Section 2.4(a).

(b) No later than forty-five (45) days following the end of each Calendar
Quarter during the CVR Term beginning with the Calendar Quarter ending on
March 31, 2021, commencing with the first CVR Payment Period in which the
Company or its Affiliates receives Gross Proceeds, the Company shall deliver to
the Rights Agent a CVR Payment Statement for the such CVR Payment Period.
Concurrent with the delivery of each CVR Payment Statement, on the terms and
conditions of this Agreement, the Company shall pay the Rights Agent in U.S.
dollars an amount equal to one-hundred percent (100%) of the Net Proceeds (if
any) (subject to the proviso in the definition of the term “CVR Payment”) for
the applicable CVR Payment Period. Such amount of Net Proceeds will be
transferred by wire transfer of immediately available funds to an account
designated in writing by the Rights Agent not less than twenty (20) Business
Days prior to the date of the applicable payment. Upon receipt of the wire
transfer referred 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 such
Holder’s CVR Payment Amount. The Rights Agent shall as soon as practicable after
receipt of a CVR Payment Statement under this Section 2.4(b), send each Holder
at its registered address a copy of such statement. For the avoidance of doubt
the Company shall have no further liability in respect of the relevant CVR Cash
Payment upon delivery of such CVR Cash Payment in accordance with this
Section 2.4(b) and the satisfaction of each of the Company’s obligations set
forth in this Section 2.4(b).

(c) The Rights Agent shall solicit 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.    That notwithstanding, the Company shall be entitled to deduct
and withhold and hereby authorizes the Rights Agent to deduct and withhold, any
tax or similar governmental charge or levy, that is required to be

 

7

--------------------------------------------------------------------------------

deducted or withheld under applicable law from any amounts payable pursuant to
this Agreement (“Withholding Taxes”). To the extent the amounts are so withheld
by the Company or the Rights Agent, as the case may be, and paid over to the
appropriate Governmental Authority, such withheld amounts shall be treated for
all purposes of this Agreement as having been paid to the person in respect of
whom such deduction and withholding was made. In the event the Company becomes
aware that a payment under this Agreement is subject to Withholding Taxes (other
than U.S. federal backup withholding), the Company shall use commercially
reasonable efforts to provide written notice to the Rights Agent and the Rights
Agent shall use commercially reasonable efforts to provide written notice of
such Withholding Taxes to the applicable Holders and the Company and the Holders
shall use commercially reasonable efforts cooperate with one another to minimize
taxes required by applicable law to be withheld or deducted from any payments
made under this Agreement. For the avoidance of doubt, in the event that notice
has been provided to an applicable Holder pursuant to this Section 2.4(c), no
further notice shall be required to be given for any future payments of such
Withholding Tax. The Company will provide withholding and reporting instructions
in writing to the Rights Agent from time to time as relevant, and upon request
of the Rights Agent. The Rights Agent shall have no responsibilities with
respect to tax withholding, reporting or payment except as specifically
instructed by the Company.

(d) Any portion of a CVR Payment that remains undistributed to the Holders six
(6) months after the applicable Calendar Quarter end (including by means of
uncashed checks or invalid addresses on the CVR Register) will be delivered by
the Rights Agent to the Company or a person nominated in writing by the Company
(with written notice thereof from the Company to the Rights Agent), and any
Holder will thereafter look only to the Company 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 Calendar 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
the Company and will be transferred to the Company or a person nominated in
writing by the Company (with written notice thereof from the Company 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 the Company 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, the Company 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 the
Company, a public office or a person nominated in writing by the Company.

Section 2.5 No Voting, Dividends or Interest; No Equity or Ownership Interest.

(a) Except for those associated with an actual CVR Share Payment, if and when
issued, the CVRs will not have any voting or dividend rights, and interest will
not accrue on any amounts payable in respect of CVRs to any Holder.

 

8

--------------------------------------------------------------------------------

(b) Except for those associated with an actual CVR Share Payment, if and when
issued, the CVRs will not represent any equity or ownership interest in the
Company or in any constituent company to the Merger. It is hereby acknowledged
and agreed that a CVR shall not constitute a security of the Company.

(c) Nothing contained in this Agreement shall be construed as conferring upon
any Holder, by virtue of the CVRs, any rights or obligations of any kind or
nature whatsoever as a stockholder or member of the Company or any of its
subsidiaries either at law or in equity. The rights of any Holder and the
obligations of the Company and its Affiliates and their respective officers,
directors and controlling Persons are contract rights limited to those expressly
set forth in this Agreement.

(d) 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 the Company’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 Amount. It is further acknowledged and agreed that neither the Company
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(d) 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 the Company or
a Person nominated in writing by the Company (with written notice thereof from
the Company 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 the Company of such transfer and cancellation. Nothing in this
Agreement is intended to prohibit the Company or its Affiliates from offering to
acquire or acquiring CVRs, in private transactions or otherwise, for
consideration in its sole discretion.

Section 2.7 Opinion of Counsel. The Company shall provide an opinion of counsel
prior to the first CVR Payment Period to set up a reserve of Common Stock. The
opinion shall state that all Common Stock, as applicable, are: registered under
the Securities Act of 1933, as amended, or are exempt from such registration;
and validly issued, fully paid and non-assessable.
