Common Stock for which the Additional Purchase Right may be exercised and the
price at which the shares may be purchased are both subject to adjustment as
provided in the Warrants. The Stock Purchase Agreement provides that ClearSign
may appoint one director to the Company&#146;s Board of Directors and Robert T.
Hoffman Sr. has been so appointed. </P>

permits clirSPV to participate in future capital raising transactions (the

Excluded from the Participation Right are the following: (i) shares of Common
Stock issued pursuant to the exercise of certain currently outstanding warrants
or options or issued pursuant to equity incentive plans or other compensation
arrangements; (ii) securities issued in debt financing transactions with any
financial institution or company; (iii) securities issued in transactions with
strategic partners such as customers, suppliers or distributors; (iv) securities
issued in rights or other securities offerings made to all stockholders; and (v)
securities issued pursuant to stockholder-approved transactions including any
transaction resulting in a change of control. Transactions with strategic
partners include, but are not limited to, (A) the consolidation or merger by
ClearSign (or its subsidiaries or affiliates) with or into (whether or not
ClearSign is the surviving corporation) another entity; (B) the sale,
assignment, transfer, conveyance or disposition of all or substantially all of
the properties or assets of ClearSign or any of its significant subsidiaries;
(C) allowing one or more entities to make, or allowing ClearSign to be subject
to or have its Common Stock be subject to, a purchase, tender or exchange offer;
(D) the consummation of a stock or share purchase agreement with a strategic
partner; or (E) the consummation with a strategic partner of any other business
combination (including, without limitation, a reorganization, recapitalization,
spin-off or scheme of arrangement). </P>
<P align=justify style="text-indent:5%">clirSPV may not exercise the
Additional Purchase Right or the Participation Right if the purchase of
additional shares of Common Stock would cause it and those whose ownership is

register the Pipe Shares for resale and to register the shares that may be
issued pursuant to the Additional Purchase Right and the Participation Right so
long as the shares purchased by other investors in the offering subject to the
Participation Right are also required to be registered. The Registration Rights
Agreement requires ClearSign to file the registration statement with the
Securities and Exchange Commission (the &#147;Commission&#148;) and to use commercially
reasonable efforts to have the registration statement declared effective by the
Commission six months after July 20, 2018. The registration rights granted to
the Investor will terminate in their entirety effective on the first date on
which there ceases to be outstanding any Registrable Securities, as defined in
the Registration Rights Agreement. </P>
