If required by law, M.I.T. shall permit any action under this Section to be brought in its name, including being joined as a party-plaintiff, provided that COMPANY shall hold M.I.T. harmless from, and indemnify M.I.T. against, any costs, expenses, or liability that M.I.T. incurs in connection with such action.

ExOne EXCL P 6-15-2011

Prior to commencing any such action, COMPANY shall consult with M.I.T. and shall consider the views of M.I.T. regarding the advisability of the proposed action and its effect on the public interest.

7.3 Declaratory Judgment Actions. In the event that a PATENT CHALLENGE is brought against M.I.T. or COMPANY by a third party, M.I.T., at its option, shall have the right within twenty (20) days after commencement of such action to take over the sole defense of the action at its own expense. If M.I.T. does not exercise this right, COMPANY may take over the sole defense of the action at COMPANY’s sole expense, subject to Sections 7.4 and 7.5.

7.4 Offsets. COMPANY may offset a total of fifty percent (50%) of any expenses incurred under Sections 7.2 and 7.3 against any payments due to M.I.T. under Article 4, provided that in no event shall such payments under Article 4, when aggregated with any other offsets and credits allowed under this Agreement, be reduced by more than fifty percent (50%) in any REPORTING PERIOD.

Any recovery obtained in an action brought by COMPANY under Sections 7.2 or 7.3 shall be distributed as follows: (i) each party shall be reimbursed for any expenses incurred in the action (including the amount of any royalty or other payments withheld from M.I.T. as described in Section 7.4), (ii) as to ordinary damages, COMPANY shall receive an amount equal to its lost profits or a reasonable royalty on the infringing sales, or whichever measure of damages the court shall have applied, and COMPANY shall pay to M.I.T. based upon such amount a reasonable approximation of the royalties and other amounts that COMPANY would have paid to M.I.T. if COMPANY had sold the infringing products, processes and services rather than the infringer, and (iii) as to special or punitive damages, the parties shall share equally in any award.

7.6 Cooperation. Each party agrees to cooperate in any action under this Article which is controlled by the other party, provided that the controlling party reimburses the cooperating party promptly for any costs and expenses incurred by the cooperating party in connection with providing such assistance.

ExOne EXCL P 6-15-2011

7.7 Right to Sublicense. So long as COMPANY remains the exclusive licensee of the PATENT RIGHTS in the EXCLUSIVE FIELD in the TERRITORY, COMPANY shall have the sole right to sublicense any alleged infringer in the EXCLUSIVE FIELD in the TERRITORY for future use of the PATENT RIGHTS in accordance with the terms and conditions of this Agreement relating to sublicenses. Any upfront fees as part of such sublicense shall be shared equally between COMPANY and M.I.T.; other revenues to COMPANY pursuant to such sublicense shall be treated as set forth in Article 4.

8. INDEMNIFICATION AND INSURANCE.

8.1 Indemnification.

(a) Indemnity. COMPANY shall indemnify, defend, and hold harmless M.I.T. and its trustees, officers, faculty, students, employees, and agents and their respective successors, heirs and assigns (the “Indemnitees”), against any liability, damage, loss, or expense (including reasonable attorneys’ fees and expenses) incurred by or imposed upon any of the Indemnitees in connection with any claims, suits, investigations, actions, demands or judgments arising out of or related to the exercise of any rights granted to COMPANY under this Agreement or any breach of this Agreement by COMPANY.

(b) Procedures. The Indemnitees agree to provide COMPANY with prompt written notice of any claim, suit, action, demand, or judgment for which indemnification is sought under this Agreement. COMPANY agrees, at its own expense, to provide attorneys reasonably acceptable to M.I.T. to defend against any such claim. The Indemnitees shall cooperate fully with COMPANY in such defense and will permit COMPANY to conduct and control such defense and the disposition of such claim, suit, or action (including all decisions relative to litigation, appeal, and settlement); provided, however, that any Indemnitee shall have the right to retain its own counsel, at the expense of COMPANY, if representation of such Indemnitee by the counsel retained by COMPANY, as reasonably agreed to by COMPANY, would be inappropriate because of actual or potential differences in the interests of such Indemnitee and any other party represented by such counsel. COMPANY agrees to keep M.I.T. informed of the progress in the defense and disposition of such claim and to consult with M.I.T. with regard to any proposed settlement.

The parties agree that any dispute arising out of or relating to this Agreement shall be resolved solely by means of the procedures set forth in this Article, and that such procedures constitute legally binding obligations that are an essential provision of this Agreement. If either party fails to observe the procedures of this Article, as may be modified by their written agreement, the other party may bring an action for specific performance of these procedures in any court of competent jurisdiction.

ExOne EXCL P 6-15-2011

13.2 Equitable Remedies. Although the procedures specified in this Article are the sole and exclusive procedures for the resolution of disputes arising out of or relating to this Agreement, either party may seek a preliminary injunction or other provisional equitable relief if, in its reasonable judgment, such action is necessary to avoid irreparable harm to itself or to preserve its rights under this Agreement.

13.3 Dispute Resolution Procedures.

(a) Mediation. In the event of any dispute arising out of or relating to this Agreement, either party may initiate mediation upon written notice to the other party (“Notice Date”) pursuant to Section 14.1, whereupon both parties shall be obligated to engage in a mediation proceeding. The mediation shall commence within forty-five (45) days of the Notice Date. The mediation shall be conducted by a single mediator in Boston, Massachusetts. The party requesting mediation shall designate two (2) or more nominees for mediator in its notice. The other party may accept one of the nominees or may designate its own nominees by notice addressed to the American Arbitration Association (AAA) and copied to the requesting party. If within, fifteen (15) days following the request for mediation, the parties have not selected a mutually acceptable mediator, a mediator shall be appointed by the AAA according to the Commercial Mediation Rules. The mediator shall attempt to facilitate a negotiated settlement of the dispute, but shall have no authority to impose any settlement terms on the parties. The expenses of the mediation shall be borne equally by the parties, but each party shall be responsible for its own counsel fees and expenses.

(b) Trial Without Jury. If the dispute is not resolved by mediation within forty-five (45) days after commencement of mediation, each party shall have the right to pursue any other remedies legally available to resolve the dispute, provided, however, that the parties expressly waive any right to a jury trial in any legal proceeding under this Article.

13.4 Performance to Continue. Each party shall continue to perform its undisputed obligations under this Agreement pending final resolution of any dispute arising out of or relating to this Agreement; provided, however, that a party may suspend performance of its undisputed obligations during any period in which the other party fails or refuses to perform its undisputed obligations. Nothing in this Article is intended to relieve COMPANY from its obligation to make undisputed payments pursuant to Articles 4 and 6 of this Agreement.

ExOne EXCL P 6-15-2011

13.5 Statute of Limitations. The parties agree that all applicable statutes of limitation and time-based defenses (including, but not limited to, estoppel and laches) shall be tolled while the procedures set forth in Sections 13.3(a) are pending. The parties shall cooperate in taking any actions necessary to achieve this result.

14. MISCELLANEOUS.

ExOne EXCL P 6-15-2011

any remedies relating thereto, shall be construed, governed, interpreted and applied in accordance with the laws of the Commonwealth of Massachusetts, U.S.A., without regard to conflict of laws principles, except that questions affecting the construction and effect of any patent shall be determined by the law of the country in which the patent shall have been granted. The state and federal courts having jurisdiction over Cambridge, MA, USA, provide the exclusive forum for any PATENT CHALLENGE and/or any court action between the parties relating to this Agreement. COMPANY submits to the jurisdiction of such courts and waives any claim that such court lacks jurisdiction over COMPANY or its AFFILIATES or constitutes an inconvenient or improper forum.

14.3 Force Majeure. Neither party will be responsible for delays resulting from causes beyond the reasonable control of such party, including without limitation fire, explosion, flood, war, strike, or riot, provided that the nonperforming party uses commercially reasonable efforts to avoid or remove such causes of nonperformance and continues performance under this Agreement with reasonable dispatch whenever such causes are removed.

14.4 Amendment and Waiver. This Agreement may be amended, supplemented, or otherwise modified only by means of a written instrument signed by both parties. Any waiver of any rights or failure to act in a specific instance shall relate only to such instance and shall not be construed as an agreement to waive any rights or fail to act in any other instance, whether or not similar.

14.5 Severability. In the event that any provision of this Agreement shall be held invalid or unenforceable for any reason, such invalidity or unenforceability shall not affect any other provision of this Agreement, and the parties shall negotiate in good faith to modify the Agreement to preserve (to the extent possible) their original intent. If the parties fail to reach a modified agreement within thirty (30) days after the relevant provision is held invalid or unenforceable, then the dispute shall be resolved in accordance with the procedures set forth in Article 13. While the dispute is pending resolution, this Agreement shall be construed as if such provision were deleted by agreement of the parties.

14.6 Binding Effect. This Agreement shall be binding upon and inure to the benefit of the parties and their respective permitted successors and assigns.

14.7 Headings. All headings are for convenience only and shall not affect the meaning of any provision of this Agreement.

Excluded Fields

Aprecia – License Agreement dated May 19, 2004

1.2 “FIELD” shall mean drug delivery products and pharmaceutical products in which such drug delivery products are implemented, in each case for human and veterinary use for all routes of administration including, without limitation, neutraceuticals and cosmetics, where such products are regulated by the U.S. Food and Drug Administration or any equivalent regulatory agency outside the United States (or any successor agency thereto).

Therics – 9^th Amendment dated 7-14-2008

“FIELD OF USE” shall mean:

(a) BIOSTRUCTURES which (i) are made directly by 3DP, (ii) consist of tricalcium phosphate (TCP) and/or polymers containing at least 10% by-weight TCP, and (iii) if marketed in the United States, would require submission to, notification of, or approval by the United States Food and Drug Administration.

(b) machines for making BIOSTRUCTURES and accessory components sold with the BIOSTRUCTURE.

(c) functional prototypes of products falling into (a) above if fabrication of such prototypes is part of an intent and agreement to manufacture the product directly by 3DP, even if such manufacturing does not take place despite the good faith efforts of the parties.

“BIOSTRUCTURE” shall mean a LICENSED PRODUCT intended for use (i) as bone replacement or bone void filler or in bone repair, (ii) in orthopedic products such as internal fixation devices, cartilage and joints, and (iii) as dental devices both above and below the gum line. A BIOSTRUCTURE may contain pharmaceuticals or other active or inactive ingredients. Notwithstanding the above, a BIOSTRUCTURE shall not mean LICENSED PRODUCT intended for use as neural tissue or repair of neural tissue.

EXCLUDED FIELDS also include matrices, scaffolds or other supportive structures which may be used in combination with cells, tissues or organs; products for the repair of vascular or tubular tissues; organs including those incorporating a temporary or permanent cell line to produce naturally occurring substances that substitute for organ function; organs and tissues used as drug delivery systems; skin healing and replacement products; those elements of in vitro diagnostic devices which interact with human biological materials and contain the reactants specific to the test being performed; products intended for use as neural tissue or repair of neural tissue; and diagnostic scaffolds.

Z Corporation – 7^th Amendment dated 8-10-2004

The exclusive “FIELD OF USE” shall consist of FOU1 defined below. The following definitions are applicable to this FIELD OF USE:

PATTERN is defined as the positive of a part which is used in a subsequent series of negative-positive transformations to achieve a final part.

MOLD or TOOL is defined as the negative of a part or portion thereof which is used in one or more subsequent processes of negative-positive transformation to achieve a final part.

VOLUME shall mean the solid volume of a part, PATTERN, MOLD, or TOOL. By example, the VOLUME of a rectangular part with dimensions a, b, and c is “a times b times c”. If the same part were to have a square d-by-d hole through its entire c dimension length, the its VOLUME would be ((a times b times c) minus (d times d times c)).

FOU1 shall mean

(a) the fabrication of appearance models, and prototypes whose purpose is for visualization or the evaluation of form, fit, function, or aesthetics;

(b) the fabrication of PATTERNS which will subsequently be used to create a mold from which a final part will be made;

(d) the manufacture and sale of machines to be used for fabrication as set forth in (a), (b), and (c) of this FOU1.
