herein as an “Approval Notice”). If either condition exists with respect to such
Indication, then (A) Exicure will provide Dermelix with reasonable evidence
thereof, including, but not limited to, by identifying the third party in
question (which evidence will be subject to Article 6 hereof), and (B) Dermelix
will not be deemed to have exercised its Option Rights with respect to such

Additional Indication under this Agreement, subject to the applicable provisions
of this Agreement. In the event that Dermelix so elects to exercise its Option
Right and provides an Option Exercise Notice to Exicure during such [***] day
period, then such Indication shall be deemed to be an Additional Indication for
all purposes under this Agreement and Dermelix shall be deemed to have exercised
one of its five (5) Option Rights for the inclusion of such Additional
Indication under this Agreement. In the event that Dermelix fails to exercise
its Option Right for such Indication during such [***] day period, then Exicure
shall no longer have any obligations of any kind whatsoever under this Agreement
to Dermelix with respect to such Indication, and Exicure shall be free to
continue to research, Develop and Commercialize SNA Therapeutics for such
Indication alone or with or through any third parties without any obligation to
Dermelix.
(c)    If, at any time during the Option Exercise Period, Exicure enters into

which to determine whether Dermelix desires to use one of its Option Rights to
add such Indication as an Additional Indication under this Agreement, subject to
the applicable provisions of this Agreement. In the event that Dermelix so
elects to exercise its Option Right and provides an Option Exercise Notice to
Exicure during such [***] day period, then such Indication shall be deemed to be
an Additional Indication for all purposes under this Agreement and Dermelix
shall be deemed to have exercised one of its five (5) Option Rights for the
inclusion of such Additional Indication under this Agreement.

Reasonable Efforts to Commercialize at least one (1) Licensed Product for the
Primary Indication and at least one (1) Licensed Product for each Additional
Indication selected by Dermelix under Section 2.4 or Section 2.5, in the
Territory in the Field. If Exicure reasonably believes that Dermelix (or its
Affiliate or Sublicensee, as applicable) has failed to use Commercially

any royalty payments to a third party for a license or other rights under or
with respect to any Patents to make, have made, use, offer for sale, sell or
import Licensed Products in the Field in any country in the Territory, then the
amount of royalties payable under Section 4.5 will be reduced by a sum equal to
[***] of the amount of such payments to such third party on account of the sale
of the Licensed Products in such country, whether such reduction is taken in
such Calendar Quarter or at any time thereafter.
(b)    Royalty Adjustment for Generic Competition. If there is Generic
Competition for a particular Licensed Product in a particular country in a
particular Calendar Quarter, then the royalty rates set forth in Section 4.5
will be reduced by [***] on sales of such Licensed Product in such country in
such Calendar Quarter.
4.7    Timing of Payment. Royalties payable under Section 4.5 will be payable on
actual Net Sales and will accrue at the time the invoice for the sale of each
Licensed Product is delivered. Royalty obligations that have accrued during a
particular Calendar Quarter will be paid, on a Calendar Quarter basis, within
forty-five (45) days after the end of each Calendar Quarter during which the
royalty obligation accrued.
4.8    Sublicense Fees. If Dermelix should receive any income as an advance or

4.10    Royalty Reports and Records Retention. Within thirty (30) days after the
end of each Calendar Quarter during which Licensed Products have been sold,
Dermelix will deliver to Exicure, together with the applicable royalty payment
due, a written report, on a Licensed Product-by-Licensed Product and a
country-by-country basis, of (a) gross invoiced amounts of sales of Licensed
Products subject to royalty payments for such Calendar Quarter, (b) amounts
deducted by category (following the definition of Net Sales) from such gross
invoiced amounts to calculate Net Sales, (c) Net Sales subject to royalty
payments for such Calendar Quarter, and (d) the corresponding royalty. Such
report will be deemed Confidential Information of Dermelix subject to the
obligations of Article 6 of this Agreement. For [five (5)] years after each sale
of a Licensed Product, Dermelix will keep (and will ensure that its Affiliates
and Sublicensees keep) complete and accurate records of all such sales in
sufficient detail to confirm the accuracy of the royalty calculations hereunder.
4.11    Late Payments. Any payments hereunder that remain unpaid for more than
thirty (30) days following their respective due dates will bear interest at the
rate of [***] per month, or the highest rate permitted by applicable law, if

duly authorized representative(s) will have the right (but not more often than
once during any year), during the Royalty Term and for three (3) years
thereafter, during regular business hours and upon at least twenty (20) days
prior notice, to audit such books of account and records and examine all other

party with respect to the subject matter and the terms of this Agreement. No
such review will unreasonably disrupt the audited party’s business operations.
All such books of account, records, documents and materials will be kept
available by each party for at least three (3) years after the end of the year
to which they relate.
(b)    If, as a result of any audit of either party’s books and records, it is
shown that such party’s payments were less (or invoices were more) than the
amount which should have been paid by an amount equal to [***] or more of the
payments that should have been made with respect to transactions occurring
during the period in question, then the audited party shall reimburse the
audited party for the reasonable cost of such audit. In any event, the audited
party shall make all payments (or reimburse all overpayments) required to be
made to eliminate any discrepancy revealed by any such audit within thirty (30)
days after demand therefor.
(c)    Each party will treat all information that it receives under this Section
4.12 in accordance with the confidentiality provisions of Article 6 of this

acceptable confidentiality agreement with the other party obligating such firm
to retain all such financial information in confidence pursuant to such
confidentiality agreement, except to the extent necessary for such party to
enforce its rights under this Agreement.
4.13    Taxes. Neither party is responsible for any sales, use, value-added,

party or if a third party challenges any Exicure Patent, Collaboration Patent,
Dermelix Patent or Dermelix SNA Patent as being invalid or unenforceable, then

relating to its own Patents, including by filing an infringement suit, defending
against such challenge or taking other similar action (each, an “Action”) and to

promptly inform the other party (the “Non-Owning Party”) in writing. If the
Owning Party does not initiate an Action with respect to such an infringement or
challenge within one hundred and eighty (180) days following written notice
thereof, the Non-Owning Party will have the right to attempt to resolve such
infringement or challenge. The party initiating such Action will have the sole
and exclusive right to select counsel for any suit initiated by it pursuant to
this Section 5.4(b).
(c)    Costs of an Action. Subject to the respective indemnity obligations of
the parties set forth in Article 8, the party taking an Action under Section
5.4(b) will pay all costs and expenses associated with such Action, other than

other party elects to join such Action. Each party will have the right to join
an Action relating to an Exicure Patent, a Collaboration Patent, a Dermelix
Patent or a Dermelix SNA Patent taken by the other party at its own cost and
expense.
(d)    Settlement. Neither party will settle or otherwise compromise any Action
by admitting that any Exicure Patent, Collaboration Patent, Dermelix Patent or
Dermelix SNA Patent is invalid or unenforceable without the other party’s prior
written consent, and, in the case of Exicure, Exicure may not settle or
otherwise compromise an Action in a way that adversely affects or would be

which the amount is paid, with Dermelix paying Exicure a royalty on such
remaining amount based on the royalty rates set forth in Section 4.5.
5.5    Third Party Actions Claiming Infringement.
(a)    Notice. If a party becomes aware of any Third Party Action, that party

expense, but not the obligation, to defend a Third Party Action described in
Section 5.5(a) and, subject to Section 5.5(f), to compromise or settle such
Third Party Action. If Dermelix declines or fails to assert its intention to
defend such Third Party Action within sixty (60) days of receipt/sending of
written notice under Section 5.5(a), then Exicure will have the right to defend
such Third Party Action. The party defending such Third Party Action will have
the sole and exclusive right to select counsel for such Third Party Action.

parties will reasonably cooperate with each other in all such actions or
proceedings. The non-Controlling Party will be entitled to be represented by
independent counsel of its own choice at its own cost and expense.
(d)    Appeal. If a judgment in a Third Party Action is entered against the
Controlling Party and an appeal is available, the Controlling Party will have
the first right, but not the obligation, to file such appeal. If the Controlling
Party does not desire to file such an appeal, it will promptly, in a reasonable
time period (i.e., with sufficient time for the non-Controlling Party to take
whatever action may be necessary) prior to the date on which such right to
appeal will lapse or otherwise diminish, permit the non-Controlling Party to
pursue such appeal at such non-Controlling Party’s own cost and expense. If

the parties set forth in Article 8, the Controlling Party will pay all costs and
expenses associated with such Third Party Action other than the costs and
expenses of the other party if the other party elects to join such Third Party
Action. Each party will have the right to join a Third Party Action defended by
the other party, at its own cost and expense.
(f)    No Settlement Without Consent. Neither party will settle or otherwise
compromise any Third Party Action by admitting that any Exicure Patent,
Collaboration Patent, Dermelix Patent or Dermelix SNA Patent is invalid or
unenforceable without the other party’s prior written consent, and, in the case
of Exicure, Exicure may not settle or otherwise compromise a Third Party Action
in a way that adversely affects or would be reasonably expected to adversely
affect Dermelix’s rights and benefits hereunder with respect to Licensed
Products, without Dermelix’s prior written consent.

ARTICLE 10 – DISPUTE RESOLUTION
10.1    Disputes. The parties recognize that disputes as to certain matters may
from time to time arise during the Term which relate to either party’s rights or
obligations under this Agreement. It is the objective of the parties to
establish under this Article 10 procedures to facilitate the resolution of
disputes arising under this Agreement in an expedient manner by mutual
cooperation and without resort to litigation. If the parties are unable to
resolve such dispute, then either party may, by written notice to the other
party, request that such dispute be submitted to the Executive Officers for
resolution, with such resolution to occur, if at all, within thirty (30) days of
their first consideration of such dispute. If the Executive Officers are unable
to resolve such dispute within thirty (30) days of their first consideration of
such dispute, then the dispute will be resolved by binding arbitration pursuant
to Section 10.2.
10.2    Binding Arbitration. Any dispute, controversy or claim arising out of or
relating to this Agreement, the subject matter hereof, or the interpretation,
performance, breach or termination hereof (other than those alleging
infringement or misappropriation of intellectual property rights,
misappropriation of trade secrets or proprietary information, violation of
confidentiality, or conduct that has or may result in irreparable harm or
otherwise warrants an application for injunctive relief), that is not resolved
by the parties as provided for in Section 10.1 will be arbitrated before the AAA
at a location in New York, New York in accordance with its Commercial
Arbitration Rules then in effect, subject to any modifications set forth in this
Section. Any such arbitration will be conducted in the English language by a
single arbitrator agreed upon by both parties or, if the parties cannot agree on
the selection of an arbitrator within twenty-one (21) days from service of an
arbitration demand, then AAA will appoint a single arbitrator as provided for in
its Commercial Arbitration Rules then in effect. The arbitrator will apply the
substantive laws of the State of New York and the arbitration will conform to
the Federal Rules of Civil Procedure and Federal Rules of Evidence. The Federal
Arbitration Act will govern the proceedings and substance of the dispute
resolution. Costs of arbitration will be shared equally by the parties, except
that the arbitrator may in his discretion impose all or part of the costs on one
of the parties. All testimony will be transcribed, and any award will be
accompanied by findings of fact and a statement of reasons for the decision.
Judgment upon any award made in such arbitration may be entered and enforced in
and by any court of competent jurisdiction. Any award by the arbitrator will be
subject to all of the terms and conditions of this Agreement. The parties will
treat as confidential any arbitration proceeding under this Section, including,
but not limited to, demands for arbitration, submissions to the arbitrator,
documents produced, any other pretrial discovery allowed by the arbitrator,
evidence taken at a hearing, as well as the arbitrator’s decision and award.
10.3    Remedies for Temporary or Preliminary Injunctive Relief. No provision of
this Section will limit the right of a party to secure temporary or preliminary
injunctive relief from a court of competent jurisdiction before, after or
during, the pendency of any arbitration. The exercise of any such remedy for
temporary or preliminary injunctive relief does not waive the right of a party
to arbitration as set forth in this Section. The institution and maintenance of
any such action for temporary or preliminary injunctive relief will not
constitute a waiver of the right

of either party to submit a dispute, controversy or claim to arbitration if the
other party contests such action for injunctive relief.
ARTICLE 11 – MISCELLANEOUS

independent contractor with respect to the other. Neither party is granted any

delegate its obligations in whole or in part without the need to obtain the
consent of the other party to: (i) an Affiliate of such party; or (ii) a
successor to all or substantially all of the business or assets of that party to

Agreement.
(c)    Subject to the foregoing, this Agreement will be binding upon and inure
to the benefit of the successors and permitted assigns of the parties hereto.
11.3    Further Actions. Each party agrees to execute, acknowledge and deliver
such further instruments and to do all such other acts as may be necessary or
appropriate in order to carry out the intent and purposes of this Agreement.
11.4    Force Majeure. Neither party will be liable to the other party or be
deemed to be in breach or default of its obligations under this Agreement for
failure or delay in the performance of any of its obligations under this
Agreement for the time and to the extent that such failure or delay is caused by
or results from acts of God, earthquake, riot, civil commotion, terrorism, war,
strikes, omissions or delays in acting by a governmental authority, acts of a
government or an agency thereof or judicial orders or decrees or restrictions,
or any other reason beyond the reasonable control of a party. The party affected
by such event of force majeure will provide the other party with full
particulars thereof as soon as it becomes aware of the same (including its best
estimate of the likely extent and duration of the interference with its
activities)

consistent with the invalid or unenforceable provision.
