STACKING ROYALTY CALCULATIONS 

R = (C * (A / (A+B))) 
 Where 

R = reduction of Licensor royalty, 

A = unreduced Licensor royalty, 
 B
= sum of all Third Party royalties, 
 C = increment of projected total royalty above [*] 

Example Calculation: 
  

									
		 	Assume:	 	i)	 	all Third Party royalties = [*]	 	
		 		 	ii)	 	unreduced Licensor royalty = [*]	 	
		 		 	iii)	 	projected total royalty = [*]	 	

  

					
		 	 R = ([*] – [*]) * ([*] / ([*] + [*]))
 R =
([*] *[*])
 R = [*]
 Licensor Stacked Royalty = [*] – [*]
= [*]% (but subject to the cap described below)
	 	

 Notwithstanding the foregoing, Licensee will pay to Licensor no less than [*]% of the royalties that
Licensee would otherwise pay to Licensor with respect to Net Sales of Licensee if there were no royalties due to Third Parties. 

3.4.2 Adjustment of Royalties For Licenses. On a Licensed Product-by-Licensed Product, country-by-country basis, upon the date on which
the manufacture, use, sale, offer for sale, or import of a Licensed Product does not infringe or is not covered by a Valid Claim in such country, then the royalty percentage applicable to Net Sales of such Licensed Product under this
Section 3.4 in such country shall be reduced by [*]%.

 CONFIDENTIAL 

 

 3.4.3 Royalty Payment Period. Licensee’s obligation hereunder for payment of a
royalty under this Section 3.4 on the Net Sales of Licensed Products in a given country will end on a country-by-country, Licensed Product-by-Licensed Product basis on the later of (i) expiration, lapse, abandonment, or invalidation of the
last Valid Claim of the Licensed Patents to expire, lapse, become abandoned or become unenforceable for the applicable Licensed Product, or (ii) [*] from the first commercial sale.

apply to any such sale or other transfer that is made in connection with a change of control of Licensee or its Affiliates. 

3.5.3 With respect to the obligations under this Section 3.5, Licensee shall not be required to submit any amounts received from a Third
Party for the following: 
  

	 	(a)	Reimbursement or payment of Licensee’s actual costs or on an arm’s length cost plus arrangement for research, development, and/or manufacturing activities performed by Licensee or its Affiliates corresponding
directly to the research, development and/or manufacturing of Licensed Products pursuant to a specific agreement; 

  

	 	(b)	Any and all amounts paid to Licensee or its Affiliates by a Sublicensee as royalties (or other similar payments, e.g., profit share) on sales of Licensed Product sold by the Sublicensee under a sublicense
agreement; and 

  

	 	(c)	Consideration received for the purchase of an equity interest in Licensee or its Affiliates at fair market value or in the form of loans at arm’s length rates of interest. 

3.5.4 If Licensee or its Affiliates receives sublicense fees from Sublicensees or from any person or entity granted any option to obtain a
sublicense under this Agreement in the form of non-cash consideration, then Licensee shall pay Licensor a cash payment as required under Section 3.5 determined based on the fair market value of such non-cash consideration. If Licensee or its
Affiliate enters into any sublicense that is not an arm’s length transaction, fees 

  

					
		 	11	 	*Confidential Treatment Requested.

due under this Section 3.5 will be calculated based on the fair market value of such transaction, at the time of the transaction, assuming an arm’s length transaction made in the
ordinary course of business, as determined jointly by Licensor and Licensee based on transactions of a similar type and standard industry practice, if any. 

3.5.5 To the extent Licensee receives payment from a Third Party relating to one or more of the milestone events set forth in the table in
Section 3.3, then the amount of the payment made to Licensor under such Section 3.3 with respect to such milestone event shall not be deemed sublicense fees under this Section 3.5; instead, the amounts due under this Section 3.5

strictly confidential; (b) protect the Confidential Information of the Disclosing Party with at least the same degree of care as it protects its own confidential and proprietary information, and in any event with not less than a reasonable
degree of care; (c) not disclose such Confidential Information to Third Parties without the prior written consent of the Disclosing Party, except as may be permitted in this Agreement; provided that any disclosure permitted hereunder shall be
under confidentiality agreements with provisions at least as stringent as those contained in this Agreement; and (d) not use such Confidential Information for purposes other

than those authorized expressly in this Agreement. The Receiving Party agrees to ensure that its employees who have access to Confidential Information are obligated in writing to abide by
confidentiality obligations at least as stringent as those contained under this Agreement. 
 5.2 Public Announcements. 

5.2.1 The Parties agree they will release a joint press release in the form attached hereto as Exhibit B. Except as provided in
Section 5.2.2, any other press releases by either Party with respect to the other Party or any other public disclosures concerning the existence of or terms of this Agreement shall be subject to review and approval by the other Party. Once the

5.2.2 Notwithstanding Section 5.2.1, Licensor has the right to publish (through press releases, scientific journals, or otherwise) and
refer to any clinical, regulatory, or research results related to Licensee’s Licensed Product or AAV8 program that have been publicly disclosed by Licensee, including referring to Licensee by name as a licensee of Licensor, which publication or

to Licensor pursuant to the terms of this Agreement, and copies of sublicense agreements provided to Licensor hereunder with the REGENXBIO Licensors to the extent required by the GSK Agreement and the Penn Agreement, under confidentiality. In the
event that the Receiving Party receives service of legal process that purports to compel disclosure of the Disclosing Party’s Confidential Information or becomes obligated by law, rule, regulation or rules of a security exchange, to disclose
the Confidential Information of the Disclosing Party or the existence of or terms of this Agreement to any governmental authority, then, to the extent legally permitted, the Receiving Party shall promptly notify the Disclosing Party, so that the
Disclosing Party may seek an appropriate protective order or other remedy with respect to narrowing the scope of such requirement and/or waive compliance by the Receiving Party with the provisions of this Agreement. The Receiving Party will, at the
Disclosing Party’s request and expense, provide the Disclosing Party with reasonable assistance in obtaining such protective order or other remedy. If, in the absence of such protective order or other remedy, the Receiving Party is nonetheless
required by law, rule, regulation or rules of a security exchange, to disclose the existence of or terms of this Agreement or other Confidential Information of the Disclosing Party, the Receiving Party may disclose such Confidential Information
without liability hereunder; provided that the Receiving Party shall furnish only such portion of the Confidential Information that is legally required to be disclosed and only to the extent required by law.

unenforceability or non-infringement of any Licensed Patents, and any notification received pursuant to subsection (k) of 42 U.S.C § 262 for any Licensed Product that becomes a “reference product.” 

7.2.2 As between Licensor and Licensee, but subject to any obligations of Licensor to the REGENXBIO Licensors, Licensor shall have the sole

Licensee shall cause each of its Affiliates and each Sublicensee to notify Licensee promptly in the event such entity becomes aware that its practice of the Licensed Patents is the subject of a claim of patent infringement by another. To the extent
Licensor takes any action, Licensor (or the REGENXBIO Licensors) shall have the right to require Licensee’s reasonable cooperation in any such suit, upon written notice to Licensee; and Licensee shall have the obligation to participate upon
Licensor’s request, in which event, Licensor shall bear the cost of Licensee’s participation. Without Licensor’s prior written permission, Licensee must not settle or compromise any such suit in a manner that imposes any material
obligations or restrictions on Licensor or the REGENXBIO Licensors or grants any rights to the Licensed Patents other than rights that Licensee has the right to grant under this Agreement.

 8.4 Indemnification. 

8.4.1 By Licensee. Licensee shall defend, indemnify, and hold harmless Licensor, the REGENXBIO Licensors, and their respective
shareholders, members, officers, trustees, faculty, students, contractors, agents, and employees (individually, a “Licensor Indemnified Party” and, collectively, the “Licensor Indemnified Parties”) from and against
any and all Third Party liability, loss, damage, action, claim, fee, cost, or expense (including attorneys’ fees) (individually, a “Third Party Liability” and, collectively, the “Third Party Liabilities”)
suffered or incurred by the Licensor Indemnified Parties from claims of such Third Parties that result from or arise out of: [*]; provided, however, that Licensee shall not be liable for claims to the extent based on any breach by Licensor of the
representations, warranties, or obligations of this Agreement or the gross negligence or intentional misconduct of any of the Licensor Indemnified Parties. Without limiting the foregoing, Licensee must defend, indemnify, and hold harmless the
Licensor Indemnified Parties from and against any Third Party Liabilities resulting from: 
  

	 	(a)	any [*] or other claim of any kind related to the [*] by a Third Party of a Licensed Product that was [*] by Licensee, its Affiliates, any Sublicensees, their respective assignees, or vendors; 

 

	 	(b)	any claim by a Third Party that [*]; and 

  

	 	(c)	[*] conducted by or on behalf of Licensee, its Affiliates, any Sublicensees, their respective assignees, or vendors relating to the Licensed Patents or Licensed Products, including any claim by or [*] 

8.4.2 By Licensor. Licensor shall defend, indemnify, and hold harmless Licensee, its shareholders, members, officers, contractors,

Parties from claims of such Third Parties that results from or arises out of: [*]; provided, however, that Licensor shall not be liable for claims based on any breach by Licensee of the representations, warranties, or obligations of this Agreement
or the gross negligence or intentional misconduct of any of the Licensee Indemnified Parties. 
 8.4.3 Indemnification Procedure.
Each Party, as an indemnifying party (an “Indemnifying Party”), shall not be permitted to settle or compromise any claim or action giving rise to Third Party Liabilities in a manner that imposes any restrictions or obligations on
any indemnified party (an “Indemnified Party”) without the other Party’s prior written consent or, if Licensee is the Indemnifying Party, that grants any rights to the Licensed Patents or Licensed Products other than those
Licensee has the right to grant under this Agreement without Licensor’s prior written consent. The Indemnifying Party shall be permitted to control any litigation or potential litigation involving the defense of any claim subject to
indemnification pursuant to this Section 8.4, including the selection of counsel, with the reasonable approval of the Indemnified Party. Upon the Indemnifying Party’s reasonable request, the Indemnified Parties will reasonably cooperate
with the Indemnifying Party in the defense and settlement of any such claim, at the Indemnifying Party’s cost and expense. If an Indemnifying Party fails or declines to assume the defense of any such claim or action within [*] after notice
thereof, the

 CONFIDENTIAL 

 

 
Indemnified Party may assume the defense of such claim or action at the cost and risk of the Indemnifying Party, and any Third Party Liabilities related thereto shall be conclusively deemed a
Third Party Liability of the Indemnifying Party. The indemnification rights of a Indemnified Party contained in this Agreement are in addition to all other rights that such Indemnified Party may have at law or in equity or otherwise. The
Indemnifying Party will pay directly all Third Party Liabilities incurred for defense or negotiation of any claim hereunder or will reimburse the Indemnified Party for all documented Third Party Liabilities incident to the defense or negotiation of
any such claim within [*] after the Indemnifying Party’s receipt of invoices for such fees, expenses, and charges. 
 8.5 Insurance. Licensee
will procure and maintain insurance policies for the following coverages with respect to product liability, personal injury, bodily injury, and property damage arising out of Licensee’s (and its Affiliates’ and any Sublicensees’)
performance under this Agreement: (a) during the term of this Agreement, comprehensive general liability, including broad form and contractual liability, in a minimum amount of [*] combined single limit per occurrence (or claim) and in the
aggregate annually; (b) prior to the commencement of clinical trials involving Licensed Products and thereafter for a period of not less than [*] (or such longer period as Licensee is required by applicable law to continue to monitor the
participants in the clinical trial), clinical trials coverage in amounts that are reasonable and customary in the U.S. pharmaceutical industry, subject always to a minimum limit of [*] combined single limit per occurrence (or claim) and in the
aggregate annually; and (c) from prior to the first commercial sale of a Licensed Product until [*] after the last sale of a Licensed Product, product liability coverage, in amounts that are reasonable and customary in the U.S. pharmaceutical
industry, subject always to a minimum limit of [*] combined single limit per occurrence (or claim) and in the aggregate annually. Licensor may review periodically the adequacy of the minimum amounts of insurance for each coverage required by this
Section 8.5, and Licensor reserves the right to require Licensee to adjust the limits accordingly. The required minimum amounts of insurance do not constitute a limitation on Licensee’s liability or indemnification obligations to the
Licensor Indemnified Parties under this Agreement. The policies of insurance required by this Section 8.5 will be issued by an insurance carrier with an A.M. best rating of [*] or better and will name Licensor as an additional insured with
respect to Licensee’s performance (and its Affiliates’ and any Sublicensees’) under this Agreement. Licensee will provide Licensor with insurance certificates evidencing the required coverage within [*] after the Effective Date and
the commencement of each policy period and any renewal periods. Each certificate will provide that the insurance carrier will notify Licensor in writing at least [*] prior to the cancellation or material change in coverage. Licensee will cause all
Sublicensees to comply with the terms of this Section 8.5 to the same extent as Licensee. 
 ARTICLE 9: USE OF NAME 

9.1 Licensee, its Affiliates, any Sublicensees, and all of its and their employees and agents must not use Licensor’s, the University of
Pennsylvania’s, or SmithKline Beecham Corporation’s name, seal, logo, trademark, or service mark (or any adaptation thereof) or the name, seal, logo, trademark, or service mark (or any adaptation thereof) of any of such entities’
representative, school, organization, employee, or student in any way without the prior written consent of Licensor or such entity, as applicable, unless required to do so pursuant to applicable law, rule, regulation or rules of a securities
exchange; provided, however that Licensee may acknowledge the existence and general nature of this Agreement, subject to Section 5.2 or 5.3, as applicable.

 CONFIDENTIAL 

 

 9.2 Licensor and all of its employees and agents must not use Licensee’s name, seal, logo, trademark, or
service mark (or any adaptation thereof) in any way without the prior written consent of Licensee; provided, however that Licensor may acknowledge the existence and general nature of this Agreement, subject to Section 5.2 or 5.3, as applicable,
and refer to Licensee as a licensee of Licensor. 
 ARTICLE 10: ADDITIONAL PROVISIONS 

10.1 Relationship. Nothing in this Agreement shall be deemed to establish a relationship of principal and agent between Licensee and Licensor, nor any
of their agents or employees for any purpose whatsoever, nor shall this Agreement be construed as creating any other form of legal association or arrangement which would impose liability upon one Party for the act or failure to act of the other
Party. 
 10.2 Assignment. The rights and obligations of Licensee and Licensor hereunder shall inure to the benefit of, and shall be binding upon,
their respective permitted successors and assigns. Licensee may not assign or otherwise transfer (by operation of law or otherwise) this Agreement or any of its rights or obligations under this Agreement without the prior written consent of Licensor
which consent is in the absolute discretion of Licensor; provided, however, Licensee shall be permitted to assign or otherwise transfer (by operation of law or otherwise ) in connection with a Change of Control without the consent of Licensor so
long as Licensee: (i) requires any assignee, transferee, or successor to agree in writing to be legally bound by this Agreement to the same extent as Licensee and provides Licensor with a copy of such undertaking; (ii) provides Licensor
with written notice of the Change of Control to Licensor within 5 days of the consummation of the transaction resulting in a Change of Control of Licensee; and (iii) provides Licensor with an unredacted copy of the definitive acquisition
agreement for the Change of Control of Licensee with 5 days of the consummation of the transaction. Notwithstanding anything to the contrary in this Agreement, for clarity, in case of a Licensee Change of Control, in no event shall any intellectual
property rights owned or controlled by the acquirer or its Affiliates immediately prior to such Licensee Change of Control be included in any of the licenses granted to Licensor under this Agreement. Licensor may assign this Agreement and its rights
and obligations without the consent of Licensee. No assignment shall relieve the assigning Party of responsibility for the performance of any accrued obligations which it has prior to such assignment. Any attempted assignment by Licensee in
violation of this Section 10.2 shall be null and void and of no legal effect. 
 10.3 Waiver. A waiver by either Party of a breach of any provision
of this Agreement will not constitute a waiver of any subsequent breach of that provision or a waiver of any breach of any other provision of this Agreement.

arbitration administered by the American Arbitration Association (“AAA”) in accordance with the Commercial Arbitration Rules of the AAA in effect on the date of commencement of
the arbitration, subject to the provisions of this Section 10.6. The arbitration shall be conducted as follows: 
 10.6.1 The
arbitration shall be conducted by three arbitrators, each of whom by training, education, or experience has knowledge of the research, development, and commercialization of biological therapeutic products in the United States. The arbitration shall
be conducted in English and held in New York, New York. 
 10.6.2 In its demand for arbitration, the Party initiating the arbitration shall
provide a statement setting forth the nature of the dispute, the names and addresses of all other parties, an estimate of the amount involved (if any), the remedy sought, otherwise specifying the issue to be resolved, and appointing one neutral
arbitrator. In an answering statement to be filed by the responding Party within [*] after confirmation of the notice of filing of the demand is sent by the AAA, the responding Party shall appoint one neutral arbitrator. Within [*] from the date on
which the responding Party appoints its neutral arbitrator, the first two arbitrators shall appoint a chairperson. 
 10.6.3 If a Party
fails to make the appointment of an arbitrator as provided in Section 10.6.2, the AAA shall make the appointment. If the appointed arbitrators fail to appoint a chairperson within the time specified in Section 10.6.2 and there is no agreed
extension of time, the AAA shall appoint the chairperson. 
 10.6.4 The arbitrators will render their award in writing and, unless all
Parties agree otherwise, will include an explanation in reasonable detail of the reasons for their award. Judgment upon the award rendered by the arbitrators may be entered in any court having jurisdiction thereof, including in the courts described
in Section 10.5. The arbitrators will have the authority to grant injunctive relief and other specific performance; provided that the arbitrators will have no authority to award damages in contravention of this Agreement, and each Party
irrevocably waives any claim to such damages in contravention of this Agreement. The arbitrators will, in rendering their decision, apply the substantive law of the State of New York, without giving effect to conflict of law provisions that may
require the application of the laws of another jurisdiction. The decision and award rendered by the arbitrators will be final and non-appealable (except for an alleged act of corruption or fraud on the part of the arbitrator). 

10.6.5 The Parties shall use their reasonable efforts to conduct all dispute resolution procedures under this Agreement as expeditiously,
efficiently, and cost-effectively as possible. 
 10.6.6 All expenses and fees of the arbitrators and expenses for hearing facilities and
other expenses of the arbitration will be borne equally by the Parties unless the Parties agree otherwise or unless the arbitrators in the award assess such expenses against one of the Parties or allocate such expenses other than equally between the
Parties. Each of the Parties will bear its own counsel fees and the expenses of its witnesses except to the extent otherwise provided in this Agreement or by applicable law.

 10.6.7 Compliance with this Section 10.6 is a condition precedent to seeking relief in
any court or tribunal in respect of a dispute, but nothing in this Section 10.6 will prevent a Party from seeking equitable or other interlocutory relief in the courts of appropriate jurisdiction, pending the arbitrators’ determination of
the merits of the controversy, if applicable to protect the confidential information, property, or other rights of that Party or to otherwise prevent irreparable harm that may be caused by the other Party’s actual or threatened breach of this
Agreement. 
 10.7 No Discrimination. Licensee and its Affiliates (and Licensee shall require that any Sublicensees), in their respective activities
under this Agreement, shall not discriminate against any employee or applicant for employment because of race, color, sex, sexual, or affectional preference, age, religion, national, or ethnic origin, handicap, or because he or she is a disabled
veteran or a veteran (including a veteran of the Vietnam Era). 
 10.8 Compliance with Law. Licensee (and its Affiliates’ and any
Sublicensees’) must comply with all prevailing laws, rules, and regulations that apply to its activities or obligations under this Agreement. Without limiting the foregoing, it is understood that this Agreement may be subject to United States
laws and regulations controlling the export of technical data, computer software, laboratory prototypes, and other commodities, articles, and information, including the Arms Export Control Act as amended in the Export Administration Act of 1979 and
that Licensee’s obligations are contingent upon compliance with applicable United States export laws and regulations. The transfer of certain technical data and commodities may require a license from the cognizant agency of the United States
Government and/or written assurances by Licensee that Licensee shall not export data or commodities to certain foreign countries without prior approval of such agency. Licensor neither represents that a license is not required nor that, if required,
it will issue. 
 10.9 Entire Agreement. This Agreement embodies the entire understanding between the Parties relating to the subject matter hereof
and supersedes all prior understandings and agreements, whether written or oral. All “Confidential Information” disclosed by the Parties pursuant to such Confidential Disclosure Agreement shall be deemed “Confidential
Information” under this Agreement (unless and until it falls within one of the exclusions set forth in Section 1.6). This Agreement may not be varied except by a written document signed by duly authorized representatives of both Parties.

 10.10 Marking. Licensee, its Affiliates, and any Sublicensees shall mark any Licensed Product (or their containers or labels) made, sold, or
otherwise distributed by it or them with any notice of patent rights necessary or desirable under applicable law to enable the Licensed Patents to be enforced to their full extent in any country where Licensed Products are made, used, sold, offered
for sale, or imported. 
 10.11 Severability and Reformation. If any provision of this Agreement is held to be invalid or unenforceable by a court of
competent jurisdiction, then such invalid or unenforceable provision will be automatically revised to be a valid or enforceable provision that comes as close as permitted by law to the Parties’ original intent; provided that, if the Parties
cannot agree upon such valid or enforceable provision, the remaining provisions of this Agreement will remain in full force and effect, unless the invalid or unenforceable provisions are of such essential importance to this Agreement that it is to
be reasonably assumed that the Parties would not have entered into this Agreement without the invalid or unenforceable provisions.

 10.12 Further Assurances. Each Party hereto agrees to execute, acknowledge, and deliver such further
instruments, and to do all other reasonable acts, as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement.

10.14 Cumulative Rights and Remedies. The rights and remedies provided in this Agreement and all other rights and remedies available to either Party at
law or in equity are, to the extent permitted by law, cumulative and not exclusive of any other right or remedy now or hereafter available at law or in equity. Neither asserting a right nor employing a remedy shall preclude the concurrent assertion
of any other right or employment of any other remedy, nor shall the failure to assert any right or remedy constitute a waiver of that right or remedy. 

10.15 Counterparts. This Agreement may be executed in one or more counterparts, each of which will be deemed an original, but all of which together
will constitute one and the same instrument.

 Exhibit B 

Press Release 
 In process
to be agreed to by both partiesBone
Biologics Corporation

Non-Employee
Director Compensation Policy

Adopted
and effective on: [______], 2015 

 

The
Non-Employee Director Compensation Policy (the “Director Compensation Policy”) was adopted
by the Board of Directors (the “Board”) of Bone Biologics Corporation (the “Company”)
and became effective on [____], 2015 (the “Effective Date”). The Director Compensation Policy may be
amended at any time in the sole discretion of the Board or the Compensation Committee of the Board.

 

Each
member of the Board who is a non-employee director of the Company (each such member, a “Non-Employee Director”)
will receive the compensation described in this Director Compensation Policy for his or her Board service following the Effective
Date.

 

A
Non-Employee Director may decline all or any portion of his or her compensation by giving notice to the Company prior to the date
cash is to be paid or equity awards are to be granted, as the case may be.

 

Annual
Cash Compensation

 

Commencing
at the beginning of the first calendar quarter following the Effective Date, each Non-Employee Director will receive the cash
compensation set forth below for service on the Board. The annual cash compensation amounts will be payable in equal quarterly
installments, in arrears following the end of each quarter in which the service occurred, pro-rated for any partial months of
service. All annual cash fees are vested upon payment.

 

	1.	Annual
    Board Service Retainer: 

 

	 	a.	All
    Non-Employee Directors other than the Board Chair: $25,000
	 	 	 
	 	b.	Non-Employee
    Director who is the Board Chair: $35,000 

 

	2.	Annual
    Committee Chair Service Retainer (in addition to Annual Board Service Retainer): 

 

	 	a.	Chairman
    of the Audit Committee: $5,000
	 	 	 
	 	b.	Chairman
    of the Compensation Committee: $5,000
	 	 	 
	 	c.	Chairman
    of the Corporate Governance Committee: $5,000

 

Equity
Compensation

 

Equity
awards will be granted under the Company’s 2015 Equity Incentive Plan or any successor equity incentive plan (the “Plan”).
All stock options granted under this Director Compensation Policy will be Nonstatutory Stock Options (as defined in the Plan),
with a term of ten years from the date of grant and an exercise price per share equal to 100% of the Fair Market Value (as defined
in the Plan) of the underlying common stock of the Company (“Common Stock”) on the date of grant.

 

    	1

    	 

    

 

(a)Automatic
Equity Grants. 

 

(i)Initial
Grant for New Directors. Without any further action of the Board, each person who, after the Effective Date, is elected or
appointed for the first time to be a Non-Employee Director will automatically, upon the date of his or her initial election or
appointment to be a Non-Employee Director, be granted a Nonstatutory Stock Option to purchase 50,000 shares of Common Stock (the
“Initial Grant”), regardless of when such person is elected or appointed to the Board. Each Initial
Grant will fully vest on the date of the annual meeting of the stockholders of the Company (“Annual Meeting”)
next following the Initial Grant.

 

(ii)Annual
Grant. Without any further action of the Board, at the close of business on the date of each Annual Meeting following the
Effective Date, each person who is then a Non-Employee Director will automatically be granted a Nonstatutory Stock Option to purchase
a number of shares of Common Stock having an Option Value (calculated on the date of grant) of $50,000 (the “Annual
Grant”). Each Annual Grant will vest in a series of four (4) successive equal quarterly installments over the one-year
period measured from the date of grant. 

 

(iii)Pro-rated
Annual Grant. If a person is elected or appointed to the Board at a time other than at the annual shareholder meeting, then
on the date of such election or appointment, the person will be automatically, and without further action by the Board, granted
an Annual Grant covering a pro-rated number of shares of Common Stock (the “Pro-rated Annual Grant”).
The Pro-rated Annual Grant will be for the number of shares of Common Stock equal to the product of (x) the number of shares of
Common Stock having an Option Value of $50,000 and (y) the Applicable Fraction, rounded down to the nearest whole share. The Applicable
Fraction means a fraction with (a) a numerator equal to the number of days between the date of the person’s initial election
or appointment to the Board and the date which is the first anniversary of the date of the most recent annual shareholder meeting
occurring before the person is elected or appointed to the Board, and (b) a denominator equal to 365. For example, if the last
annual shareholder meeting was held on June 1, 2015, and a person is appointed to the Board for the first time on August 1, 2015,
the Applicable Fraction would be 304/365. The vesting commencement date of the Pro-rated Annual Grant will be the date of the
most recent annual shareholder meeting occurring before the person is elected or appointed to the Board. For example, if the last
annual shareholder meeting was held on June 1, 2015, and a person is appointed to the Board for the first time on August 1, 2015,
the Annual Grant will fully vest on June 1, 2016.

 

(b)Vesting;
Change of Control. All vesting is subject to the Non-Employee Director’s “Continuous Service”
(as defined in the Plan) on each applicable vesting date. Notwithstanding the foregoing vesting schedules, for each Non-Employee
Director who remains in Continuous Service with the Company until immediately prior to the effective time of a “Change
of Control” (as defined in the Plan), the shares subject to his or her then-outstanding equity awards that were
granted pursuant to this policy will become fully vested immediately prior to the effective time of such Change of Control.

 

(c)Calculation
of Option Value. The “Option Value” of a stock option to be granted under this policy will be determined
using the same method that the Company uses to calculate the grant-date fair value of stock options in its financial statements.

 

    	2

    	 

    

 

(d)Remaining
Terms. The remaining terms and conditions of each stock option, including transferability, will be as set forth in the Company’s
standard Option Agreement, in the form adopted from time to time by the Board. 

 

Expenses

 

The
Company will reimburse Non-Employee Director for ordinary, necessary and reasonable out-of-pocket travel expenses to cover in-person
attendance at and participation in Board and committee meetings; provided, that the Non-Employee Director timely submit
to the Company appropriate documentation substantiating such expenses in accordance with the Company’s travel and expense
policy, as in effect from time to time.
