 Exhibit 10.1 

FORM OF INDEMNIFICATION AGREEMENT 

This Indemnification Agreement (“Agreement”) is made as of [•], 2017 by and between Molecular Templates, Inc., (formerly, Threshold
Pharmaceuticals, Inc.) a Delaware corporation (the “Company”), and [•] (the “Indemnitee”). This Agreement supersedes and replaces any and all previous Agreements between the Company and Indemnitee covering the subject matter
of this Agreement. 
 RECITALS 

WHEREAS, highly competent persons have become more reluctant to serve publicly-held corporations as directors, officers or in other capacities unless they are
provided with adequate protection through insurance or adequate indemnification against inordinate risks of claims and actions against them arising out of their service to and activities on behalf of the corporation; 

WHEREAS, the Board of Directors of the Company (the “Board”) has determined that, in order to attract and retain qualified individuals, the Company
will attempt to maintain on an ongoing basis, at its sole expense, liability insurance to protect persons serving the Company and its subsidiaries from certain liabilities. Although the furnishing of such insurance has been a customary and
widespread practice among United States-based corporations and other business enterprises, the Company believes that, given current market conditions and trends, such insurance may be available to it in the future only at higher premiums and with
more exclusions. At the same time, directors, officers, and other persons in service to corporations or business enterprises are being increasingly subjected to expensive and time-consuming litigation relating to, among other things, matters that
traditionally would have been brought only against the Company or business enterprise itself. The Company’s Bylaws require indemnification of the officers and directors of the Company. Indemnitee may also be entitled to indemnification pursuant
to the General Corporation Law of the State of Delaware (the “DGCL”). The Bylaws and the DGCL expressly provide that the indemnification provisions set forth therein are not exclusive, and thereby contemplate that contracts may be entered
into between the Company and members of the board of directors, officers and other persons with respect to indemnification; 
 WHEREAS, the uncertainties
relating to such insurance and to indemnification have increased the difficulty of attracting and retaining such persons; 
 WHEREAS, the Board has
determined that the increased difficulty in attracting and retaining such persons is detrimental to the best interests of the Company and its stockholders and that the Company should act to assure such persons that there will be increased certainty
of such protection in the future; 
 WHEREAS, it is reasonable, prudent and necessary for the Company contractually to obligate itself to indemnify, and to
advance expenses on behalf of, such persons to the fullest extent permitted by applicable law so that they will serve or continue to serve the Company free from undue concern that they will not be so indemnified; 

WHEREAS, this Agreement is a supplement to and in furtherance of the Bylaws and any resolutions adopted pursuant thereto, and shall not be deemed a substitute
therefor, nor to diminish or abrogate any rights of Indemnitee thereunder; [and] 
 WHEREAS, Indemnitee does not regard the protection available under the
Bylaws and insurance as adequate in the present circumstances, and may not be willing to serve as an officer or director without adequate protection, and the Company desires Indemnitee to serve in such capacity. Indemnitee is willing to serve,
continue to serve and to take on additional service for or on behalf of the Company on the condition that he be so indemnified; [and] 
 [WHEREAS,
Indemnitee is a representative of [•] [and its affiliated investment funds] (the “Fund”), and has certain rights to indemnification and/or insurance provided by the Fund which Indemnitee and the Fund intend to be secondary to the
primary obligation of the Company to indemnify Indemnitee as provided herein, with the Company’s acknowledgement and agreement to the foregoing being a material condition to Indemnitee’s willingness to serve on the Board;] 

 NOW, THEREFORE, in consideration of the premises and the covenants contained herein, the Company and Indemnitee
do hereby covenant and agree as follows: 
 Section 1. Services to the Company. Indemnitee agrees to serve as a[n] [director] [and] [officer] of
the Company. Indemnitee may at any time and for any reason resign from such position (subject to any other contractual obligation or any obligation imposed by operation of law), in which event the Company shall have no obligation under this
Agreement to continue Indemnitee in such position. This Agreement shall not be deemed an employment contract between the Company (or of its subsidiaries or any Enterprise) and Indemnitee. Indemnitee specifically acknowledges that Indemnitee’s
employment with the Company (or of its subsidiaries or any Enterprise), if any, is at will, and the Indemnitee may be discharged at any time for any reason, with or without cause, except as may be otherwise provided in any written employment
contract between Indemnitee and the Company (or of its subsidiaries or any Enterprise), other applicable formal severance policies duly adopted by the Board, or, with respect to service as a director or officer of the Company, by the Certificate of
Incorporation, the Company’s Bylaws, and the DGCL. The foregoing notwithstanding, this Agreement shall continue in force after Indemnitee has ceased to serve as a[n] [director] [or] [officer] of the Company, as provided in Section 16
hereof. 
 Section 2. Definitions. As used in this Agreement: 

(a) References to “agent” shall mean any person who is or was a director, officer, or employee of the Company or a subsidiary of the Company or other
person authorized by the Company to act for the Company, to include such person serving in such capacity as a director, officer, employee, fiduciary or other official of another corporation, partnership, limited liability company, joint venture,
trust or other enterprise at the request of, for the convenience of, or to represent the interests of the Company or a subsidiary of the Company. 
 (b) A
“Change in Control” shall be deemed to occur upon the earliest to occur after the date of this Agreement of any of the following events: 
 i.
Acquisition of Stock by Third Party. Any Person (as defined below) is or becomes the Beneficial Owner (as defined below), directly or indirectly, of securities of the Company representing forty percent (40%) or more of the combined
voting power of the Company’s then outstanding securities unless the change in relative Beneficial Ownership of the Company’s securities by any Person results solely from a reduction in the aggregate number of outstanding shares of
securities entitled to vote generally in the election of directors; 
 ii. Change in Board of Directors. During any period of two (2) consecutive
years (not including any period prior to the execution of this Agreement), individuals who at the beginning of such period constitute the Board, and any new director (other than a director designated by a person who has entered into an agreement
with the Company to effect a transaction described in Sections 2(b)(i), 2(b)(iii) or 2(b)(iv)) whose election by the Board or nomination for election by the Company’s stockholders was approved by a vote of at least two-thirds of the directors then still in office who either were directors at the beginning of the period or whose election or nomination for election was previously so approved, cease for any reason to constitute
at least a majority of the members of the Board; 
 iii. Corporate Transactions. The effective date of a merger or consolidation of the Company with
any other entity, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior to such merger or consolidation continuing to represent (either by remaining outstanding or by being
converted into voting securities of the surviving entity or its ultimate parent, as applicable) more than 51% of the combined voting power of the voting securities of the surviving entity or its ultimate parent, as applicable, outstanding
immediately after such merger or consolidation and with the power to elect at least a majority of the board of directors or other governing body of such surviving entity or its ultimate parent, as applicable; 

iv. Liquidation or Sale of Assets. The approval by the stockholders of the Company of a complete liquidation of the Company or an agreement for the sale
or disposition by the Company of all or substantially all of the Company’s assets; and

nature that would be required to be reported in response to Item 6(e) of Schedule 14A of Regulation 14A (or a response to any similar item on any similar schedule or form) promulgated under the Exchange Act (as defined below), whether or not
the Company is then subject to such reporting requirement. 

 For purposes of this Section 2(b), the following terms shall have the following meanings: 

(A) “Exchange Act” shall mean the Securities Exchange Act of 1934, as amended from time to time. 

(B) “Person” shall have the meaning as set forth in Sections 13(d) and 14(d) of the Exchange Act; provided, however, that Person shall exclude
(i) the Company, (ii) any trustee or other fiduciary holding securities under an employee benefit plan of the Company, and (iii) any corporation owned, directly or indirectly, by the stockholders of the Company in substantially the
same proportions as their ownership of stock of the Company. 
 (C) “Beneficial Owner” shall have the meaning given to such term in Rule 13d-3 under the Exchange Act; provided, however, that Beneficial Owner shall exclude any Person otherwise becoming a Beneficial Owner by reason of the stockholders of the Company approving a merger of the Company
with another entity. 
 (c) “Corporate Status” describes the status of a person as a current or former director or officer of the Company or as a
current or former director, manager, partner, officer, employee, agent, or trustee of any other entity or enterprise that such person is or was serving at the request of the Company. 

(d) “Disinterested Director” shall mean a director of the Company who is not and was not a party to the Proceeding in respect of which
indemnification is sought by Indemnitee. 
 (e) “Enterprise” shall mean the Company and any other corporation, limited liability company,
partnership, joint venture, trust or other enterprise of which Indemnitee is or was serving at the request of the Company as a director, officer, trustee, partner, managing member, employee, agent or fiduciary. 

(f) “Expenses” shall include all reasonable attorneys’ fees, retainers, court costs, transcript costs, fees of experts and other professionals,
witness fees, travel expenses, duplicating costs, printing and binding costs, telephone charges, postage, delivery service fees, any federal, state, local or foreign taxes imposed on Indemnitee as a result of the actual or deemed receipt of any
payments under this Agreement, ERISA excise taxes and penalties, and all other disbursements or expenses of the types customarily incurred in connection with prosecuting, defending, preparing to prosecute or defend, investigating, being or preparing
to be a witness in, or otherwise participating in, a Proceeding. Expenses also shall include (i) Expenses incurred in connection with any appeal resulting from any Proceeding, including without limitation the premium, security for, and other
costs relating to any cost bond, supersedeas bond, or other appeal bond or its equivalent, and (ii) for purposes of Section 14(d) only, Expenses incurred by Indemnitee in connection with the interpretation, enforcement or defense of
Indemnitee’s rights under this Agreement, by litigation or otherwise. The parties agree that for the purposes of any advancement of Expenses for which Indemnitee has made written demand to the Company in accordance with this Agreement, all
Expenses included in such demand that are certified by affidavit of Indemnitee’s counsel as being reasonable shall be presumed conclusively to be reasonable. Expenses, however, shall not include amounts paid in settlement by Indemnitee or the
amount of judgments or fines against Indemnitee. 
 (g) “Independent Counsel” shall mean a law firm, or a member of a law firm, that is experienced
in matters of corporation law and neither presently is, nor in the past five years has been, retained to represent: (i) the Company or Indemnitee in any matter material to either such party (other than with respect to matters concerning the
Indemnitee under this Agreement, or of other indemnitees under similar indemnification agreements), or (ii) any other party to the Proceeding giving rise to a claim for indemnification hereunder. Notwithstanding the foregoing, the term
“Independent Counsel” shall not include any person who, under the applicable standards of professional conduct then prevailing, would have a conflict of interest in representing either the Company or Indemnitee in an action to determine
Indemnitee’s rights under this Agreement. The Company agrees to pay the reasonable fees and expenses of the Independent Counsel referred to above and to fully indemnify such counsel against any and all Expenses, claims, liabilities and damages
arising out of or relating to this Agreement or its engagement pursuant hereto. 
 (h) The term “Proceeding” shall include any threatened, pending
or completed action, suit, claim, counterclaim, cross claim, arbitration, mediation, alternate dispute resolution mechanism, investigation, inquiry, administrative hearing or any other actual, threatened or completed proceeding, whether brought in
the right of the Company or otherwise and whether of a civil, criminal, administrative, legislative, or investigative (formal or informal) nature, including any appeal therefrom, in which Indemnitee was, is or will be involved as a party, potential
party, non-party witness or otherwise by reason of the fact that Indemnitee is or was a director or officer of the Company, by reason of any action taken by him (or a failure to take action by him) or of any
action (or failure to act) on his part while acting pursuant to his Corporate Status, in each case whether or not serving in such capacity at the time any liability or Expense is incurred for which indemnification, reimbursement, or advancement of
Expenses can be provided under this Agreement. If the Indemnitee believes in good faith that a given situation may lead to or culminate in the institution of a Proceeding, this shall be considered a Proceeding under this paragraph. 

 (i) Reference to “other enterprise” shall include employee benefit plans; references to
“fines” shall include any excise tax assessed with respect to any employee benefit plan; references to “serving at the request of the Company” shall include any service as a director, officer, employee or agent of the Company
which imposes duties on, or involves services by, such director, officer, employee or agent with respect to an employee benefit plan, its participants or beneficiaries; and a person who acted in good faith and in a manner he reasonably believed to
be in the best interests of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in manner “not opposed to the best interests of the Company” as referred to in this Agreement. 

Section 3. Indemnity in Third-Party Proceedings. The Company shall indemnify Indemnitee in accordance with the provisions of this Section 3
if Indemnitee is, or is threatened to be made, a party to or a participant in any Proceeding, other than a Proceeding by or in the right of the Company to procure a judgment in its favor. Pursuant to this Section 3, Indemnitee shall be
indemnified to the fullest extent permitted by applicable law against all Expenses, judgments, fines and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of such
Expenses, judgments, fines and amounts paid in settlement) actually and reasonably incurred by Indemnitee or on his behalf in connection with such Proceeding or any claim, issue or matter therein, if Indemnitee acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the Company and, in the case of a criminal Proceeding had no reasonable cause to believe that his conduct was unlawful. The parties hereto intend that this Agreement shall provide
to the fullest extent permitted by law for indemnification in excess of that expressly permitted by statute, including, without limitation, any indemnification provided by the Certificate of Incorporation, the Bylaws, vote of its stockholders or
disinterested directors or applicable law. 
 Section 4. Indemnity in Proceedings by or in the Right of the Company. The Company shall indemnify
Indemnitee in accordance with the provisions of this Section 4 if Indemnitee is, or is threatened to be made, a party to or a participant in any Proceeding by or in the right of the Company to procure a judgment in its favor. Pursuant to this
Section 4, Indemnitee shall be indemnified to the fullest extent permitted by applicable law against all Expenses actually and reasonably incurred by him or on his behalf in connection with such Proceeding or any claim, issue or matter therein,
if Indemnitee acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Company. No indemnification for Expenses shall be made under this Section 4 in respect of any claim, issue or matter
as to which Indemnitee shall have been finally adjudged by a court to be liable to the Company, unless and only to the extent that the Delaware Court of Chancery (the “Delaware Court”) or any court in which the Proceeding was brought shall
determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, Indemnitee is fairly and reasonably entitled to indemnification for such Expenses as the Delaware Court or other court shall
deem proper. 
 Section 5. Indemnification for Expenses of a Party Who is Wholly or Partly Successful. Notwithstanding any other provisions of
this Agreement, to the fullest extent permitted by applicable law and to the extent that Indemnitee is a party to (or a participant in) and is successful, on the merits or otherwise, in any Proceeding or in defense of any claim, issue or matter
therein, in whole or in part, the Company shall indemnify Indemnitee against all Expenses actually and reasonably incurred by him in connection therewith. If Indemnitee is not wholly successful in such Proceeding but is successful, on the merits or
otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall indemnify Indemnitee against all Expenses actually and reasonably incurred by him or on his behalf in connection with or related to each
successfully resolved claim, issue or matter to the fullest extent permitted by law. For purposes of this Section and without limitation, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice,
shall be deemed to be a successful result as to such claim, issue or matter. 
 Section 6. Indemnification For Expenses of a Witness.
Notwithstanding any other provision of this Agreement, to the fullest extent permitted by applicable law and to the extent that Indemnitee is, by reason of his Corporate Status, a witness or otherwise asked to participate in any Proceeding to which
Indemnitee is not a party, he shall be indemnified against all Expenses actually and reasonably incurred by him or on his behalf in connection therewith. 

 Section 7. Partial Indemnification. If Indemnitee is entitled under any provision of this Agreement
to indemnification by the Company for some or a portion of Expenses, but not, however, for the total amount thereof, the Company shall nevertheless indemnify Indemnitee for the portion thereof to which Indemnitee is entitled. 

Section 8. Additional Indemnification. 
 (a)
Notwithstanding any limitation in Sections 3, 4, or 5, the Company shall indemnify Indemnitee to the fullest extent permitted by applicable law if Indemnitee is a party to or threatened to be made a party to any Proceeding (including a Proceeding by
or in the right of the Company to procure a judgment in its favor) against all Expenses, judgments, fines and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of such
Expenses, judgments, fines and amounts paid in settlement) actually and reasonably incurred by Indemnitee in connection with the Proceeding. 
 (b) For
purposes of Section 8(a), the meaning of the phrase “to the fullest extent permitted by applicable law” shall include, but not be limited to: 

i. to the fullest extent permitted by the provision of the DGCL that authorizes or contemplates additional indemnification by agreement, or the corresponding
provision of any amendment to or replacement of the DGCL, and 
 ii. to the fullest extent authorized or permitted by any amendments to or replacements of
the DGCL adopted after the date of this Agreement that increase the extent to which a corporation may indemnify its officers and directors. 

Section 9. Exclusions. Notwithstanding any provision in this Agreement [but subject to Section 15(e), however], the Company shall not be
obligated under this Agreement to make any indemnification payment in connection with any claim made against Indemnitee: 
 (a) for which payment has
actually been made to or on behalf of Indemnitee under any insurance policy or other indemnity provision, except with respect to any excess beyond the amount paid under any insurance policy or other indemnity provision; or 

(b) for (i) an accounting of profits made from the purchase and sale (or sale and purchase) by Indemnitee of securities of the Company within the meaning
of Section 16(b) of the Exchange Act (as defined in Section 2(b) hereof) or similar provisions of state statutory law or common law, or (ii) any reimbursement of the Company by the Indemnitee of any bonus or other incentive-based or
equity-based compensation or of any profits realized by the Indemnitee from the sale of securities of the Company, as required in each case under the Exchange Act (including any such reimbursements that arise from an accounting restatement of the
Company pursuant to Section 304 of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), or the payment to the Company of profits arising from the purchase and sale by Indemnitee of securities in violation of Section 306 of
the Sarbanes-Oxley Act); or 
 (c) except as provided in Section 14(d) of this Agreement, in connection with any Proceeding (or any part of any
Proceeding) initiated by Indemnitee, including any Proceeding (or any part of any Proceeding) initiated by Indemnitee against the Company or its directors, officers, employees or other indemnitees, unless (i) the Board authorized the Proceeding
(or any part of any Proceeding) prior to its initiation or (ii) the Company provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company under applicable law. 

Section 10. Advances of Expenses. Notwithstanding any provision of this Agreement to the contrary (other than Section 14(d)), the Company
shall advance, to the extent not prohibited by law, the Expenses incurred by Indemnitee in connection with any Proceeding (or any part of any Proceeding) not initiated by Indemnitee, and such advancement shall be made within twenty (20) days
after the receipt by the Company of a statement or statements requesting such advances from time to time, whether prior to or after final disposition of any Proceeding. Advances shall be unsecured and interest free. Advances shall be made without
regard to Indemnitee’s ability to repay the Expenses and without regard to Indemnitee’s ultimate entitlement to indemnification under the other provisions of this Agreement. In accordance with Section 14(d), advances shall include any
and all reasonable Expenses incurred pursuing an action to enforce this right of advancement, including Expenses incurred preparing and forwarding statements to the Company to support the advances claimed. The Indemnitee shall qualify for advances
upon the execution and delivery to the Company of this Agreement, which shall constitute an undertaking providing that the Indemnitee undertakes to repay the amounts advanced (without interest) to the extent that it is ultimately determined that
Indemnitee is not entitled to be indemnified by the Company. No other form of undertaking shall be required other than the execution of this Agreement. This Section 10 shall not apply to any claim made by Indemnitee for which indemnity is
excluded pursuant to Section 9. 

 Section 11. Procedure for Notification and Defense of Claim. 

(a) Indemnitee shall notify the Company in writing of any matter with respect to which Indemnitee intends to seek indemnification or advancement of Expenses
hereunder as soon as reasonably practicable following the receipt by Indemnitee of written notice thereof. The written notification to the Company shall include a description of the nature of the Proceeding and the facts underlying the Proceeding.
To obtain indemnification under this Agreement, Indemnitee shall submit to the Company a written request, including therein or therewith such documentation and information as is reasonably available to Indemnitee and is reasonably necessary to
determine whether and to what extent Indemnitee is entitled to indemnification following the final disposition of such Proceeding. The omission by Indemnitee to notify the Company hereunder will not relieve the Company from any liability which it
may have to Indemnitee hereunder or otherwise than under this Agreement, and any delay in so notifying the Company shall not constitute a waiver by Indemnitee of any rights under this Agreement. The Secretary of the Company shall, promptly upon
receipt of such a request for indemnification, advise the Board in writing that Indemnitee has requested indemnification. 
 (b) The Company will be entitled
to participate in the Proceeding at its own expense. 
 Section 12. Procedure Upon Application for Indemnification. 

(a) Upon written request by Indemnitee for indemnification pursuant to Section 11(a), a determination, if required by applicable law, with respect to
Indemnitee’s entitlement thereto shall be made in the specific case: (i) if a Change in Control shall have occurred, by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to Indemnitee; or
(ii) if a Change in Control shall not have occurred, (A) by a majority vote of the Disinterested Directors, even though less than a quorum of the Board, (B) by a committee of Disinterested Directors designated by a majority vote of
the Disinterested Directors, even though less than a quorum of the Board, (C) if there are no such Disinterested Directors or, if such Disinterested Directors so direct, by Independent Counsel in a written opinion to the Board, a copy of which
shall be delivered to Indemnitee or (D) if so directed by the Board, by the stockholders of the Company; and, if it is so determined that Indemnitee is entitled to indemnification, payment to Indemnitee shall be made within ten (10) days
after such determination. Indemnitee shall cooperate with the person, persons or entity making such determination with respect to Indemnitee’s entitlement to indemnification, including providing to such person, persons or entity upon reasonable
advance request any documentation or information which is not privileged or otherwise protected from disclosure and which is reasonably available to Indemnitee and reasonably necessary to such determination. Any costs or Expenses (including
attorneys’ fees and disbursements) incurred by Indemnitee in so cooperating with the person, persons or entity making such determination shall be borne by the Company (irrespective of the determination as to Indemnitee’s entitlement to
indemnification) and the Company hereby indemnifies and agrees to hold Indemnitee harmless therefrom. The Company promptly will advise Indemnitee in writing with respect to any determination that Indemnitee is or is not entitled to indemnification,
including a description of any reason or basis for which indemnification has been denied. 
 (b) In the event the determination of entitlement to
indemnification is to be made by Independent Counsel pursuant to Section 12(a) hereof, the Independent Counsel shall be selected as provided in this Section 12(b). If a Change in Control shall not have occurred, the Independent Counsel
shall be selected by the Board, and the Company shall give written notice to Indemnitee advising him of the identity of the Independent Counsel so selected. If a Change in Control shall have occurred, the Independent Counsel shall be selected by
Indemnitee (unless Indemnitee shall request that such selection be made by the Board, in which event the preceding sentence shall apply), and Indemnitee shall give written notice to the Company advising it of the identity of the Independent Counsel
so selected. In either event, Indemnitee or the Company, as the case may be, may, within ten (10) days after such written notice of selection shall have been given, deliver to the Company or to Indemnitee, as the case may be, a written
objection to such selection; provided, however, that such objection may be asserted only on the ground that the Independent Counsel so selected does not meet the requirements of “Independent Counsel” as defined in
Section 2 of this Agreement, and the objection shall set forth with particularity the factual basis of such assertion. Absent a proper and timely objection, the person so selected shall act as Independent Counsel. If such written objection is
so made and substantiated, the Independent Counsel so selected may not serve as Independent Counsel 

 
unless and until such objection is withdrawn or the Delaware Court has determined that such objection is without merit. If, within twenty (20) days after the later of submission by
Indemnitee of a written request for indemnification pursuant to Section 11(a) hereof and the final disposition of the Proceeding, no Independent Counsel shall have been selected and not objected to, either the Company or Indemnitee may petition
the Delaware Court for resolution of any objection which shall have been made by the Company or Indemnitee to the other’s selection of Independent Counsel and/or for the appointment as Independent Counsel of a person selected by such court or
by such other person as such court shall designate, and the person with respect to whom all objections are so resolved or the person so appointed shall act as Independent Counsel under Section 12(a) hereof. Upon the due commencement of any
judicial proceeding or arbitration pursuant to Section 14(a) of this Agreement, Independent Counsel shall be discharged and relieved of any further responsibility in such capacity (subject to the applicable standards of professional conduct
then prevailing). 
 Section 13. Presumptions and Effect of Certain Proceedings. 

(a) In making a determination with respect to entitlement to indemnification hereunder, the person or persons or entity making such determination shall, to the
fullest extent not prohibited by law, presume that Indemnitee is entitled to indemnification under this Agreement if Indemnitee has submitted a request for indemnification in accordance with Section 11(a) of this Agreement, and the Company
shall, to the fullest extent not prohibited by law, have the burden of proof to overcome that presumption in connection with the making by any person, persons or entity of any determination contrary to that presumption. Neither the failure of the
Company (including by its directors or Independent Counsel) to have made a determination prior to the commencement of any action pursuant to this Agreement that indemnification is proper in the circumstances because Indemnitee has met the applicable
standard of conduct, nor an actual determination by the Company (including by its directors or Independent Counsel) that Indemnitee has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that
Indemnitee has not met the applicable standard of conduct. 
 (b) Subject to Section 14(e), if the person, persons or entity empowered or selected under
Section 12 of this Agreement to determine whether Indemnitee is entitled to indemnification shall not have made a determination within sixty (60) days after receipt by the Company of the request therefor, the requisite determination of
entitlement to indemnification shall, to the fullest extent not prohibited by law, be deemed to have been made and Indemnitee shall be entitled to such indemnification, absent (i) a misstatement by Indemnitee of a material fact, or an omission
of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law; provided, however, that such 60-day period may be extended for a reasonable time, not to exceed an additional thirty (30) days, if the person, persons or entity making the determination with respect to entitlement to indemnification in
good faith requires such additional time for the obtaining or evaluating of documentation and/or information relating thereto; and provided, further, that the foregoing provisions of this Section 13(b) shall not apply (i) if the
determination of entitlement to indemnification is to be made by the stockholders pursuant to Section 12(a) of this Agreement and if (A) within fifteen (15) days after receipt by the Company of the request for such determination the
Board has resolved to submit such determination to the stockholders for their consideration at an annual meeting thereof to be held within seventy-five (75) days after such receipt and such determination is made thereat, or (B) a special
meeting of stockholders is called within fifteen (15) days after such receipt for the purpose of making such determination, such meeting is held for such purpose within sixty (60) days after having been so called and such determination is
made thereat, or (ii) if the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 12(a) of this Agreement. 

(c) The termination of any Proceeding or of any claim, issue or matter therein, by judgment, order, settlement or conviction, or upon a plea of nolo
contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) of itself adversely affect the right of Indemnitee to indemnification or create a presumption that Indemnitee did not act in good faith and in
a manner which he reasonably believed to be in or not opposed to the best interests of the Company or, with respect to any criminal Proceeding, that Indemnitee had reasonable cause to believe that his conduct was unlawful. 

(d) For purposes of any determination of good faith, Indemnitee shall be deemed to have acted in good faith if Indemnitee’s action is based on the records
or books of account of the Enterprise, including financial statements, or on information supplied to Indemnitee by the directors or officers of the Enterprise in the course of their duties, or on the advice of legal counsel for the Enterprise or on
information or records given or reports made to the Enterprise by an independent certified public accountant or by an appraiser or other expert selected with the reasonable care by the Enterprise. The provisions of this Section 13(d) shall not
be deemed to be exclusive or to limit in any way the other circumstances in which the Indemnitee may be deemed to have met the applicable standard of conduct set forth in this Agreement. 

 (e) The knowledge and/or actions, or failure to act, of any director, officer, trustee, partner, managing member,
fiduciary, agent or employee of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement. 

Section 14. Remedies of Indemnitee. 
 (a) Subject to
Section 14(e), in the event that (i) a determination is made pursuant to Section 12 of this Agreement that Indemnitee is not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made
pursuant to Section 10 of this Agreement, (iii) no determination of entitlement to indemnification shall have been made pursuant to Section 12(a) of this Agreement within ninety (90) days after receipt by the Company of the
request for indemnification, (iv) payment of indemnification is not made pursuant to Section 5, 6 or 7 or the last sentence of Section 12(a) of this Agreement within ten (10) days after receipt by the Company of a written request
therefor, (v) payment of indemnification pursuant to Section 3, 4 or 8 of this Agreement is not made within ten (10) days after a determination has been made that Indemnitee is entitled to indemnification, or (vi) in the event
that the Company or any other person takes or threatens to take any action to declare this Agreement void or unenforceable, or institutes any litigation or other action or Proceeding designed to deny, or to recover from, the Indemnitee the benefits
provided or intended to be provided to the Indemnitee hereunder, Indemnitee shall be entitled to an adjudication by a court of his entitlement to such indemnification or advancement of Expenses. Alternatively, Indemnitee, at his option, may seek an
award in arbitration to be conducted by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association. Indemnitee shall commence such proceeding seeking an adjudication or an award in arbitration within 180
days following the date on which Indemnitee first has the right to commence such proceeding pursuant to this Section 14(a); provided, however, that the foregoing clause shall not apply in respect of a proceeding brought by
Indemnitee to enforce his rights under Section 5 of this Agreement. The Company shall not oppose Indemnitee’s right to seek any such adjudication or award in arbitration. 

(b) In the event that a determination shall have been made pursuant to Section 12(a) of this Agreement that Indemnitee is not entitled to indemnification,
any judicial proceeding or arbitration commenced pursuant to this Section 14 shall be conducted in all respects as a de novo trial, or arbitration, on the merits and Indemnitee shall not be prejudiced by reason of that adverse
determination. In any judicial proceeding or arbitration commenced pursuant to this Section 14, the Company shall have the burden of proving Indemnitee is not entitled to indemnification or advancement of Expenses, as the case may be. 

(c) If a determination shall have been made pursuant to Section 12(a) of this Agreement that Indemnitee is entitled to indemnification, the Company shall
be bound by such determination in any judicial proceeding or arbitration commenced pursuant to this Section 14, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make
Indemnitee’s statement not materially misleading, in connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law. 

(d) The Company shall, to the fullest extent not prohibited by law, be precluded from asserting in any judicial proceeding or arbitration commenced pursuant to
this Section 14 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court or before any such arbitrator that the Company is bound by all the provisions of this Agreement.
It is the intent of the Company that, to the fullest extent permitted by law, the Indemnitee not be required to incur legal fees or other Expenses associated with the interpretation, enforcement or defense of Indemnitee’s rights under this
Agreement by litigation or otherwise because the cost and expense thereof would substantially detract from the benefits intended to be extended to the Indemnitee hereunder. The Company shall, to the fullest extent permitted by law, indemnify
Indemnitee against any and all Expenses and, if requested by Indemnitee, shall (within ten (10) days after receipt by the Company of a written request therefor) advance, to the extent not prohibited by law, such Expenses to Indemnitee, which
are incurred by Indemnitee in connection with any action brought by Indemnitee for indemnification or advance of Expenses from the Company under this Agreement or under any directors’ and officers’ liability insurance policies maintained
by the Company if, in the case of indemnification, Indemnitee is wholly successful on the underlying claims; if Indemnitee is not wholly successful on the underlying claims, then such indemnification shall be only to the extent Indemnitee is
successful on such underlying claims or otherwise as permitted by law, whichever is greater. 

 (e) Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement of Indemnitee
to indemnification under this Agreement shall be required to be made prior to the final disposition of the Proceeding. 
 Section 15. Non-exclusivity; Survival of Rights; Insurance; Subrogation. 
 (a) The rights of indemnification and to receive
advancement of Expenses as provided by this Agreement shall not be deemed exclusive of any other rights to which Indemnitee may at any time be entitled under applicable law, the Certificate of Incorporation, the Bylaws, any agreement, a vote of
stockholders or a resolution of directors, or otherwise. No amendment, alteration or repeal of this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted
by such Indemnitee in his Corporate Status prior to such amendment, alteration or repeal. To the extent that a change in Delaware law, whether by statute or judicial decision, permits greater indemnification or advancement of Expenses than would be
afforded currently under the Certificate of Incorporation and this Agreement, it is the intent of the parties hereto that Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change. No right or remedy herein conferred
is intended to be exclusive of any other right or remedy, and every other right and remedy shall be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The
assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other right or remedy. 

(b) To the extent that the Company maintains an insurance policy or policies providing liability insurance for directors, officers, employees, or agents of the
Enterprise, Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any such director, officer, employee or agent under such policy or policies. If, at the time
of the receipt of a notice of a claim pursuant to the terms hereof, the Company has director and officer liability insurance in effect, the Company shall give prompt notice of such claim or of the commencement of a Proceeding, as the case may be, to
the insurers in accordance with the procedures set forth in the respective policies. The Company shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of the Indemnitee, all amounts payable as a result of
such Proceeding in accordance with the terms of such policies. 
 (c) In the event of any payment under this Agreement, the Company shall be subrogated to
the extent of such payment to all of the rights of recovery of Indemnitee [(other than any rights of recovery of Indemnitee from a Fund Indemnitor (as defined in Section 15(e) hereof) or under any insurance provided by the Fund or its
affiliates)], who shall execute all papers required and take all action necessary to secure such rights, including execution of such documents as are necessary to enable the Company to bring suit to enforce such rights. 

(d) [Except as provided for under Section 15(e) of this Agreement, the] The Company shall not be liable under this Agreement to make any payment of
amounts otherwise indemnifiable (or for which advancement is provided hereunder) hereunder if and to the extent that Indemnitee has otherwise actually received such payment under any insurance policy, contract, agreement or otherwise. 

(e) [The Company hereby acknowledges that Indemnitee has certain rights to indemnification, advancement of expenses and/or insurance provided by the Fund and
certain of its affiliates (collectively, the “Fund Indemnitors”). The Company hereby agrees (i) that it is the indemnitor of first resort (i.e., its obligations to Indemnitee are primary and any obligation of the Fund Indemnitors to
advance expenses or to provide indemnification for the same expenses or liabilities incurred by Indemnitee are secondary), (ii) that it shall be required to advance the full amount of Expenses incurred by Indemnitee and shall be liable for the
full amount of all Expenses, judgments, penalties, fines and amounts paid in settlement to the extent legally permitted and as required by the Certificate of Incorporation or Bylaws (or any agreement between the Company and Indemnitee), without
regard to any rights Indemnitee may have against the Fund Indemnitors, and, (iii) that it irrevocably waives, relinquishes and releases the Fund Indemnitors from any and all claims against the Fund Indemnitors for contribution, subrogation or
any other recovery of any kind in respect thereof. The Company further agrees that no advancement or payment by the Fund Indemnitors on behalf of Indemnitee with respect to any claim for which Indemnitee has sought indemnification from the Company
shall affect the foregoing and the Fund Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of Indemnitee against the Company. The Company and Indemnitee
agree that the Fund Indemnitors are express third party beneficiaries of the terms hereof.] 

 (f) The Company’s obligation to indemnify or advance Expenses hereunder to Indemnitee who is or was serving
at the request of the Company as a director, officer, trustee, partner, managing member, fiduciary, employee or agent of any other corporation, limited liability company, partnership, joint venture, trust, employee benefit plan or other enterprise
shall be reduced by any amount Indemnitee has actually received as indemnification or advancement of Expenses from such other corporation, limited liability company, partnership, joint venture, trust or other enterprise. 

Section 16. Duration of Agreement. This Agreement shall continue until and terminate upon the later of: (a) ten (10) years after the
date that Indemnitee shall have ceased to serve as a [director] [or] [officer] of the Company or (b) one (1) year after the final termination of any Proceeding then pending in respect of which Indemnitee is granted rights of
indemnification or advancement of Expenses hereunder and of any proceeding commenced by Indemnitee pursuant to Section 14 of this Agreement [or by a Fund Indemnitor pursuant to Section 15(e) of this Agreement, in either case,] relating
thereto. The indemnification and advancement of expenses rights provided by or granted pursuant to this Agreement shall be binding upon and be enforceable by the parties hereto and their respective successors and assigns (including any direct or
indirect successor by purchase, merger, consolidation or otherwise to all or substantially all of the business or assets of the Company), shall continue as to an Indemnitee who has ceased to be a director, officer, employee or agent of the Company
or of any other Enterprise, and shall inure to the benefit of Indemnitee and his or her spouse, assigns, heirs, devisees, executors and administrators and other legal representatives. 

Section 17. Severability. If any provision or provisions of this Agreement shall be held to be invalid, illegal or unenforceable for any reason
whatsoever: (a) the validity, legality and enforceability of the remaining provisions of this Agreement (including without limitation, each portion of any Section of this Agreement containing any such provision held to be invalid, illegal or
unenforceable, that is not itself invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby and shall remain enforceable to the fullest extent permitted by law; (b) such provision or provisions shall be deemed
reformed to the extent necessary to conform to applicable law and to give the maximum effect to the intent of the parties hereto; and (c) to the fullest extent possible, the provisions of this Agreement (including, without limitation, each
portion of any Section of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall be construed so as to give effect to the intent manifested thereby. 

Section 18. Enforcement. 
 (a) The Company expressly
confirms and agrees that it has entered into this Agreement and assumed the obligations imposed on it hereby in order to induce Indemnitee to serve as a director or officer of the Company, and the Company acknowledges that Indemnitee is relying upon
this Agreement in serving as a director or officer of the Company. 
 (b) This Agreement constitutes the entire agreement between the parties hereto with
respect to the subject matter hereof and supersedes all prior agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject matter hereof, including without limitation any previous indemnification
agreements, which are hereby terminated in full; provided, however, that this Agreement is a supplement to and in furtherance of the Certificate of Incorporation, the Bylaws and applicable law, and shall not be deemed a substitute therefor, nor to
diminish or abrogate any rights of Indemnitee thereunder. 
 Section 19. Modification and Waiver. No supplement, modification or amendment of
this Agreement shall be binding unless executed in writing by the parties hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions of this Agreement nor shall any waiver
constitute a continuing waiver. 
 Section 20. Notice by Indemnitee. Indemnitee agrees promptly to notify the Company in writing upon being
served with any summons, citation, subpoena, complaint, indictment, information or other document relating to any Proceeding or matter which may be subject to indemnification or advancement of Expenses covered hereunder. The failure of Indemnitee to
so notify the Company shall not relieve the Company of any obligation which it may have to the Indemnitee under this Agreement or otherwise. 

 Section 21. Notices. All notices, requests, demands and other communications under this Agreement
shall be in writing and shall be deemed to have been duly given if (a) delivered by hand and receipted for by the party to whom said notice or other communication shall have been directed, (b) mailed by certified or registered mail with
postage prepaid, on the third business day after the date on which it is so mailed, (c) mailed by reputable overnight courier and receipted for by the party to whom said notice or other communication shall have been directed or (d) sent by

unavailable to Indemnitee for any reason whatsoever, the Company, in lieu of indemnifying Indemnitee, shall contribute to the amount incurred by Indemnitee, whether for judgments, fines, penalties, excise taxes, amounts paid or to be paid in
settlement and/or for Expenses, in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and reasonable in light of all of the circumstances of such Proceeding in order to reflect
(i) the relative benefits received by the Company, on the one hand, and Indemnitee, on the other hand, as a result of the event(s) and/or transaction(s) giving cause to such Proceeding; and/or (ii) the relative fault of the Company (and
its other directors, officers, employees and agents), on the one hand, and Indemnitee, on the other hand, in connection with such event(s) and/or transaction(s).

United States of America or any court in any other country, (ii) consent to submit to the exclusive jurisdiction of the Delaware Court for purposes of any action or proceeding arising out of or in connection with this Agreement,
(iii) appoint, to the extent such party is not otherwise subject to service of process in the State of Delaware, irrevocably the Corporation Trust Center as its agent in the State of Delaware as such party’s agent for acceptance of legal
process in connection with any such action or proceeding against such party with the same legal force and validity as if served upon such party personally within the State of Delaware, (iv) waive any objection to the laying of venue of any such
action or proceeding in the Delaware Court, and (v) waive, and agree not to plead or to make, any claim that any such action or proceeding brought in the Delaware Court has been brought in an improper or inconvenient forum.

be an original but all of which together shall constitute one and the same Agreement. Only one such counterpart signed by the party against whom enforceability is sought needs to be produced to evidence the existence of this Agreement.

(c) Each Investor shall have executed and delivered the Transaction Documents to the Company. 

6.3 Termination of Obligations to Effect Closing; Effects. 

(a) The obligations of the Company, on the one hand, and the Investors, on the other hand, to effect the Closing shall terminate as follows:

 (i) Upon the mutual written consent of the Company and the Investors; 

(ii) By the Company if any of the conditions set forth in Section 6.2 shall have become incapable of fulfillment,
and shall not have been waived by the Company; 

 (iii) By an Investor (with respect to itself only) if any of the conditions set forth in
Section 6.1 shall have become incapable of fulfillment, and shall not have been waived by such Investor; or 

(iv) By either the Company or any Investor (with respect to itself only) if the Closing has not occurred prior to 11:59 PM (New York time) on
August 1, 2017; 
 provided, however, that, except in the case of clause (i) above, the party seeking to terminate its obligation to effect the
Closing shall not then be in breach of any of its representations, warranties, covenants or agreements contained in this Agreement or the other Transaction Documents if such breach has resulted in the circumstances giving rise to such party’s
seeking to terminate its obligation to effect the Closing. 
 (b) In the event of termination by the Company or any Investor of its
obligations to effect the Closing pursuant to this Section 6.3, written notice thereof shall forthwith be given to the other Investors by the Company and the other Investors shall have the right to terminate their
obligations to effect the Closing upon written notice to the Company and the other Investors. Nothing in this Section 6.3 shall be deemed to release any party from any liability for any breach by such party of the terms and
provisions of this Agreement or the other Transaction Documents or to impair the right of any party to compel specific performance by any other party of its obligations under this Agreement or the other Transaction Documents. 

7. Other Covenants and Agreements of the Parties. 

7.1 Disclosure of Material Non-Public Information. The Company shall not disclose material non-public information to the Investors, or to advisors to or representatives of the Investors, unless prior to disclosure of such information the Company identifies such information as being material non-public information and provides the Investors, such advisors and representatives with the opportunity to accept or refuse to accept such material non-public information
for review and any Investor wishing to obtain such information enters into an appropriate confidentiality agreement with the Company with respect thereto. 

7.2 Listing of Registrable Securities. The Company shall promptly secure and maintain the listing of all of the Registrable Securities
(as defined in the Registration Rights Agreement) pursuant to the terms set forth in the Registration Rights Agreement. 
 7.3
Legends. The Securities shall bear the following legends: 
 (a) “The securities represented hereby have not been registered
with the Securities and Exchange Commission or the securities commission of any state in reliance upon an exemption from registration under the Securities Act of 1933, as amended, and, accordingly, may not be transferred unless (i) such
securities have been registered for sale pursuant to the Securities Act of 1933, as amended, (ii) such securities may be sold pursuant to Rule 144, or (iii) the Company has received an opinion of counsel reasonably satisfactory to it that
such transfer may lawfully be made without registration under the Securities Act of 1933, as amended.” 
 (b) If required by the
authorities of any state in connection with the issuance of sale of the Securities, the legend required by such state authority. 

 7.4 Removal of Legends. 

(a) In connection with any sale, assignment, transfer or other disposition of the Securities by an Investor pursuant to Rule 144 or pursuant
to any other exemption under the Securities Act such that the purchaser acquires freely tradable securities and upon compliance by such Investor with the requirements of this Agreement, if requested by such Investor, the Company shall cause the
Transfer Agent to timely remove any restrictive legends related to the book entry account holding such Securities and make a new, unlegended entry for such book entry Securities sold or disposed of without restrictive legends, provided that the
Company has received from the Investor customary representations and other documentation reasonably acceptable to the Company in connection therewith. 

(b) Subject to receipt from the Investor by the Company and the Transfer Agent of customary representations and other customary documentation
reasonably acceptable to the Company and the Transfer Agent in connection therewith, upon the earliest of (i) the Securities being subject to an effective registration statement covering the resale of the Securities, (ii) such time as the
Securities have been sold pursuant to Rule 144, or (iii) such time as the Securities are eligible for resale under Rule 144(b)(1) or any successor provision, the Company shall (A) deliver to the Transfer Agent irrevocable instructions that
the Transfer Agent shall make a new, unlegended entry for such book entry Securities, together with either (1) a customary representation by the Investor that Rule 144 applies to the Securities represented thereby or (2) a statement by the
Investor that such Investor has sold the Securities represented thereby in accordance with the plan of distribution contained in the Registration Statement, and (B) cause its counsel to deliver to the Transfer Agent one or more opinions to the
effect that the removal of such legends in such circumstances may be effected under the Securities Act if required by the Transfer Agent to effect the removal of the legend in accordance with the provisions of this Agreement. The Company agrees that
following such time as such legend is no longer required under this Section 7.4, it will, upon an Investor’s written request and compliance with the immediately preceding sentence, deliver or cause to be delivered to
such Investor, a certificate representing that such Securities are free from all restrictive and other legends. Securities subject to legend removal hereunder shall be transmitted by the Transfer Agent to the Investor by crediting the account of the
Investor’s custodian as directed by such Investor. 
 7.5 Furnishing of Information. In order to enable the Investors to sell
the Securities under Rule 144, until the date that the Shares and the Warrant Shares cease to be Registrable Securities (as defined in the Registration Rights Agreement), the Company shall use its commercially reasonable efforts to timely file (or
obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the Effective Date pursuant to the Exchange Act. During such period, if the Company is not required to file
reports pursuant to the Exchange Act, it will prepare and furnish to the Investors and make publicly available in accordance with Rule 144(c) such information as is required for the Investors to sell the Securities under Rule 144. 

 7.6 Indemnification of Investors. Subject to the provisions of this
Section 7.6, the Company will indemnify and hold each Investor harmless from any and all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses, including all judgments, amounts paid in
settlements, court costs and reasonable attorneys’ fees and costs of investigation, that any such Investor may suffer or incur as a result of or relating to any breach of any of the representations, warranties, covenants or agreements made by
the Company in this Agreement; provided, however, that the aggregate liability of the Company to each Investor under this Section 7.6 shall not exceed the amount paid by such Investor to the Company pursuant
to Section 3. Promptly after receipt by any Investor (the “Indemnified Person”) of notice of any demand or claim from any Person that would or might give rise to a claim or the commencement of any action,
proceeding or investigation in respect of which indemnification may be sought pursuant to this Section 7.6 (a “Third Party Claim”), such Indemnified Person shall promptly notify the Company in writing, and
in reasonable detail, of such Third Party Claim. Thereafter, the Indemnified Person will deliver to the Company, within five (5) Business Days after the Indemnified Person’s receipt thereof, copies of all notices and documents (including
court papers) received by the Indemnified Person relating to the Third Party Claim. If a Third Party Claim is made against the Company, the Company will be entitled to participate in the defense thereof and, if it so chooses, to assume the defense
thereof (subject to a reservation of rights) with counsel selected by the Company by giving the Indemnified Person notice within twenty (20) days of the Company’s receipt of notice of the Third Party Claim pursuant to this
Section 7.6. If the Company does not give such notice to the Indemnified Person of the Company’s intent to assume the defense of the Third Party Claim, the Indemnified Person shall be entitled to assume the defense
thereof. Should the Company so elect to assume the defense of a Third Party Claim, the Company will not be liable to the Indemnified Person for legal expenses subsequently incurred by the Indemnified Person in connection with the defense thereof. If
the Company assumes such defense, the Indemnified Person will have the right to participate in the defense thereof and to employ counsel, at its own expense, separate from the counsel employed by the Company, it being understood, however, that the
Company will control such defense. If the Company chooses to defend any Third Party Claim, then all the Parties will cooperate in the defense or prosecution of such Third Party Claim. The Indemnified Person will not admit any liability with respect
to, or settle, compromise or discharge, any Third Party Claim without the prior written consent of the Company. Notwithstanding any other provision of this Agreement, the Company shall not enter into settlement of any Third Party Claim without the
prior written consent of the Indemnified Person (which consent shall not be unreasonably withheld), unless such settlement requires only the payment of money that the Company is obligated to pay. 

7.7 Equal Treatment of Investors. No consideration shall be offered or paid to any Person to amend or consent to a waiver or
modification of any provision of any of the Transaction Documents unless the same consideration is also offered to all of the Parties to the Transaction Documents. For clarification purposes, this provision constitutes a separate right granted to
each Investor by the Company and negotiated separately by each Investor, and is intended for the Company to treat the Investors as a class and shall not in any way be construed as the Investors acting in concert or as a group with respect to the
purchase, disposition or voting of Securities or otherwise. 

 7.8 Compliance with Laws. Notwithstanding any other provision of this Agreement,
each Investor covenants that the Securities may be disposed of only pursuant to an effective registration statement under, and in compliance with the requirements of, the Securities Act, or pursuant to an available exemption from, or in a
transaction not subject to, the registration requirements of the Securities Act, and in compliance with any applicable state and federal securities Laws. In connection with any transfer of the Securities other than (i) pursuant to an effective
registration statement, (ii) to the Company, (iii) pursuant to Rule 144 (provided that the Investor provides the Company with reasonable assurances (in the form of seller and, if applicable, broker representation letters) that the
Securities may be sold pursuant to such rule), or (iv) to its Affiliates, the Company may require the transferor thereof to provide to the Company an opinion of counsel selected by the transferor and reasonably acceptable to the Company, the
form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such transferred Securities under the Securities Act. As a condition of transfer, any such
transferee shall agree in writing to be bound by the terms of this Agreement and shall have the rights of an Investor under this Agreement with respect to such transferred Securities. 

7.9 Termination of Certain Obligations. The provisions of Sections 7.1 and 7.2 shall terminate and be of no further force
and effect on the date on which the Company’s obligations under the Registration Rights Agreement to register or maintain the effectiveness of any registration covering the Registrable Securities (as defined in the Registration Rights
Agreement) shall terminate. 
 8. Survival. The representations, warranties, covenants and agreements contained in this Agreement
shall survive for a period of one (1) year following the Closing. 
 9. Miscellaneous. 

9.1 Assignment. This Agreement may not be assigned by a party hereto without the prior written consent of the Company or the Investors,
as applicable. 
 9.2 Successors. This Agreement shall be binding solely on, and inure solely to the benefit of, each of the
undersigned and their respective successors and permitted assigns, and nothing set forth in this Agreement shall be construed to confer upon or give to any Person other than each of the undersigned and their respective successors and permitted
assigns any benefits, rights or remedies under or by reason of, or any rights to enforce or cause the Company to enforce, the equity commitment or any provisions of this Agreement. 

9.3 Counterparts; Faxes; Electronic Mail. This Agreement may be executed in two or more counterparts, each of which shall be deemed an
original, but all of which together shall constitute one and the same instrument. This Agreement may also be executed via facsimile or electronic mail, each of which shall be deemed an original. 

9.4 Titles and Subtitles. The titles and subtitles used in this Agreement are used for convenience only and are not to be considered in
construing or interpreting this Agreement. 

 9.5 Notices. Unless otherwise provided, any notice required or permitted under this
Agreement shall be given in writing and shall be deemed effectively given as hereinafter described (i) if given by personal delivery, then such notice shall be deemed given upon such delivery; (ii) if given by facsimile, then such notice
shall be deemed given upon receipt of confirmation of complete transmittal; (iii) if given by mail, then such notice shall be deemed given upon the earlier of (A) receipt of such notice by the recipient or (B) three (3) days after
such notice is deposited in first class mail, postage prepaid; and (iv) if given by an internationally recognized overnight air courier, then such notice shall be deemed given one (1) Business Day after delivery to such carrier. All
notices shall be addressed to the party to be notified at the address as follows, or at such other address as such party may designate by ten (10) days’ advance written notice to the other party:

9.6 Expenses. The Parties shall pay their own costs and expenses in connection herewith; provided, however, following the
Closing, the Company shall pay the reasonable fees and expenses of Longitude Venture Partners III, L.P., including its reasonable attorney’s fees and costs, up to a maximum aggregate amount of $175,000. In the event that legal proceedings are
commenced by any party to this Agreement against another party to this Agreement in connection with any Transaction Document, the party or parties to such proceeding which do not prevail in such proceedings shall severally, but not jointly, pay
their pro rata share of the reasonable attorneys’ fees and other reasonable out-of-pocket costs and expenses incurred by the prevailing party in such proceedings.

 9.7 Amendments and Waivers. Any term of this Agreement may be amended and the observance of any term of this Agreement may be
waived (either generally or in a particular instance and either retroactively or prospectively) only with the written consent of the Company and the Required Investors. Any amendment or waiver effected in accordance with this paragraph shall be
binding upon each holder of any Securities purchased under this Agreement at the time outstanding, each future holder of all such Securities, and the Company. 

 9.8 Publicity. Except as set forth below, no public release or announcement concerning the
transactions contemplated hereby shall be issued by the Company or the Investors without the prior written consent of the Company (in the case of a release or announcement by the Investors) or the Required Investors (in the case of a release or
announcement by the Company) (which consents shall not be unreasonably withheld), except (i) as such release or announcement may be required by Law or the applicable rules or regulations of the SEC, any securities exchange or securities market,
in which case the Company or the Investors, as the case may be, shall allow the Investors or the Company, as applicable, to the extent reasonably practicable in the circumstances, reasonable time to comment on such release or announcement in advance
of such issuance or (ii) a public release or announcement in connection with discussions to investors not including the Required Investors, in which case such consent shall not be required. Notwithstanding the foregoing, no Investor may be
named in a public release or announcement concerning the transactions contemplated hereby without such Investor’s prior written consent. The Investors hereby acknowledge and agree that no later than the fourth (4th) Business Day after the Effective Date, the Company shall (x) issue a press release reasonably acceptable to the Required Investors and (y) file a Current Report on Form 8-K describing the terms of the transactions contemplated by the Transaction Documents in the form required by the Exchange Act and attaching the material Transaction Documents (including, without limitation, this
Agreement (and all schedules and exhibits to this Agreement), the form of Warrant and the Registration Rights Agreement, as exhibits to such filing (including all attachments)). In addition, the Company will make such other filings and notices in
the manner and time required by the SEC or the NASDAQ Capital Market, the Warrants and the Registration Rights Agreement. 
 9.9
Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining
provisions hereof but shall be interpreted as if it were written so as to be enforceable to the maximum extent permitted by applicable Law, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable
such provision in any other jurisdiction. To the extent permitted by applicable Law, the Parties hereby waive any provision of Law which renders any provision hereof prohibited or unenforceable in any respect. 

9.10 Entire Agreement. This Agreement, including the Exhibits, the Warrants and the Registration Rights Agreement constitute the entire
agreement among the Parties with respect to the subject matter hereof and thereof and supersede all prior agreements and understandings, both oral and written, among the Parties with respect to the subject matter hereof and thereof. 

9.11 Further Assurances. The Parties shall execute and deliver all such further instruments and documents and take all such other
actions as may reasonably be required to carry out the transactions contemplated hereby and to evidence the fulfillment of the agreements herein contained. 

9.12 Governing Law; Consent to Jurisdiction; Waiver of Jury Trial. This Agreement shall be governed by, and construed in accordance
with, the internal Laws of the State of Delaware without regard to the choice of law principles thereof. Each of the Parties irrevocably submits to the exclusive jurisdiction of the courts of the Delaware Court of Chancery and any state appellate
court therefrom within the State of Delaware Court of Chancery and any 

 
state appellate court therefrom within the State of Delaware (or, if the Delaware Court of Chancery declines to accept jurisdiction over a particular mater, any state or federal court within the
State of Delaware) for the purpose of any suit, action, proceeding or judgment relating to or arising out of this Agreement and the transactions contemplated hereby. Service of process in connection with any such suit, action or proceeding may be
served on each party hereto anywhere in the world by the same methods as are specified for the giving of notices under this Agreement. Each of the Parties irrevocably consents to the jurisdiction of any such court in any such suit, action or
proceeding and to the laying of venue in such court. Each party hereto irrevocably waives any objection to the laying of venue of any such suit, action or proceeding brought in such courts and irrevocably waives any claim that any such suit, action
or proceeding brought in any such court has been brought in an inconvenient forum. EACH OF THE PARTIES WAIVES ANY RIGHT TO REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS AGREEMENT AND REPRESENTS THAT COUNSEL HAS BEEN CONSULTED
SPECIFICALLY AS TO THIS WAIVER. 
 9.13 Disclaimer. Except as expressly set forth in this Agreement, no Party makes any
representation or warranty to any other Party of any nature, express or implied. Each Investor acknowledges and agrees that in evaluating its investment in the Securities, it is not relying on any representations, warranties or information
(including the accuracy or completeness thereof) other than the representations and warranties contained herein and the information contained in the SEC Filings. 

9.14 Independent Nature of Investors’ Obligations and Rights. The obligations of each Investor under any Transaction Document are
several and not joint with the obligations of any other Investor, and no Investor shall be responsible in any way for the performance of the obligations of any other Investor under any Transaction Document. The decision of each Investor to purchase
Securities pursuant to the Transaction Documents has been made by such Investor independently of any other Investor. Nothing contained in any Transaction Document, and no action taken by any Investor pursuant thereto, shall be deemed to constitute
the Investors as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Investors are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated
by the Transaction Documents. Each Investor acknowledges that no other Investor has acted as agent for such Investor in connection with making its investment hereunder and that no Investor will be acting as agent of such Investor in connection with
monitoring its investment in the Securities or enforcing its rights under the Transaction Documents. Each Investor shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of the
Transaction Documents, and it shall not be necessary for any other Investor to be joined as an additional party in any proceeding for such purpose. The Company acknowledges that each of the Investors has been provided with the same Transaction
Documents for the purpose of closing a transaction with multiple Investors and not because it was required or requested to do so by any Investor.
