If you sign and submit your proxy card without specifying how you would like your shares voted, your shares
will be voted in accordance with the Boards recommendations specified above under What are the Boards voting recommendations? and in accordance with the discretion of the proxy holders with respect to any other matters that
may be voted upon at the Annual Meeting.
How do I access the Annual Meeting Online?
The Annual Meeting will be conducted virtually via a webcast available at www.virtualshareholdermeeting.com/KRYS2021. You are entitled to participate in the
Annual meeting via the webcast if you were a stockholder as of the close of business on the Record Date or hold a valid proxy for the meeting. To be admitted to the annual meeting at www.virtualshareholdermeeting.com/KRYS2021, you must enter the 16-digit control number found next to the label Control Number for postal mail recipients or within the body of the email sending you the Proxy Statement. If you do not have your 16-digit control number, you will be able to login as a guest but will not be able to vote your shares or submit questions during the meeting.
If I plan to attend the Annual Meeting, should I still vote by proxy?
Yes. Voting in advance does not affect your right to attend the Annual Meeting. If you send in your proxy card and attend the Annual Meeting, you do not need
to vote again at the Annual Meeting unless you want to change your vote. You will be able to vote at the Annual Meeting using your 16-digit control number. Any votes cast with respect to a particular control
number at the Annual Meeting will cancel any prior votes associated with that control number.
How are proxy card votes counted?
If the proxy card is properly signed and returned to us, and not subsequently revoked, it will be voted as directed by you. Unless contrary instructions are
given, the persons designated as proxy holders on the proxy card will vote: FOR the election of all nominees for the Board named in this Proxy Statement; FOR the ratification of the appointment of Mayer Hoffman as our
independent registered public accounting firm for the fiscal year ending December 31, 2021; and as recommended by the Board with regard to any other matters that may properly come before the Annual Meeting, or, if no such recommendation is
given, in their own discretion.
May I revoke my vote after I return my proxy card?
Yes. You may revoke a previously granted proxy and change your vote at any time before the taking of the vote at the Annual Meeting by (i) filing with our
Secretary a written notice of revocation or a duly executed proxy bearing a later date or (ii) attending the Annual Meeting and voting in person.
Who pays the costs of soliciting proxies?

year ended December 31, 2020, coordination of the Internet and telephone voting process, and any additional information furnished to you by the Company. Copies of solicitation materials will be furnished to banks, brokerage houses, fiduciaries
