 Section 2 
 Registration Rights 
  
 2.1 Requested Registration. 
  
 (a) Request for Registration. Subject to the
conditions set forth in this Section 2.1, if the Company shall receive from Initiating Holders a written request signed by such Initiating Holders that the Company effect any registration with respect to Registrable Securities held by
such Initiating Holders, provided such request states the number of shares of Registrable Securities to be disposed of and the intended methods of disposition of such shares by such Initiating Holders, the Company will: 
  
 (i) promptly give written notice of the proposed
registration to all other Holders; and 
  
 (ii)
file and use its best efforts to effect such registration within ninety (90) days of such written request from the Initiating Holders (including, without limitation, filing post-effective amendments, appropriate qualifications under applicable
blue sky or other state securities laws, and appropriate compliance with the Securities Act) and to permit or facilitate the sale and distribution of all or such portion of such Registrable Securities as are specified in such request, together with
all or such portion of the Registrable Securities of any Holder or Holders joining in such request as are specified in a written request received by the Company within twenty (20) days after such written notice from the Company is mailed or
delivered. 
  
 (b) Limitations on Requested
Registration. The Company shall not be obligated to effect, or to take any action to effect, any such registration pursuant to this Section 2.1: 
  
 (i) Prior to the earlier of (x) the Company’s Initial Public Offering or (y) August 2,
2011; 
  
 (ii) During the one hundred eighty
(180) days following the effective date of the first registration statement filed by the Company covering an underwritten offering of any of its securities to the general public, except upon receipt of the written consent of the applicable
underwriter(s); 
  
 (iii) If the Initiating
Holders, together with the holders of any other securities of the Company entitled to inclusion in such registration statement, propose to sell Registrable Securities and such other securities (if any) the aggregate proceeds of which (after
deduction for underwriter’s discounts and expenses related to the issuance) are less than $500,000. 
  
 (iv) In any particular jurisdiction in which the Company would be required to execute a general consent to service of process in effecting
such registration, qualification, or compliance, unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act; 
  
 (v) After the Company has initiated two (2) such registrations pursuant to this
Section 2.1; 
  

 -4- 

 (vi) If the Initiating Holders propose to dispose of shares of Registrable Securities
which may be immediately registered on Form S-3 pursuant to a request made under Section 2.3 hereof; or 
  
 (vii) If the Company, within thirty (30) days of its receipt of the request from the Initiating Holders, provides written notice to
all Initiating Holders of its intent to file a registration statement for its Initial Public Offering within ninety (90) days. 
  
 (c) Deferral. If (i) in the good faith judgment of the board of directors of the Company (the “Board”), the
filing of a registration statement covering the Registrable Securities would be detrimental to the Company and the Board concludes, as a result, that it is in the best interests of the Company to defer the filing of such registration statement at
such time, and (ii) the Company shall furnish to such Holders a certificate signed by the President of the Company stating that in the good faith judgment of the Board, it would be detrimental to the Company for such registration statement to
be filed in the near future and that it is, therefore, in the best interests of the Company to defer the filing of such registration statement, then (in addition to the limitations set forth in Section 2.1(b) above) the Company shall
have the right to defer such filing for a period of not more than one hundred eighty (180) days after receipt of the request of the Initiating Holders, and, provided further, that the Company shall not defer its obligation in this manner more
than once in any twelve-month period. 
  
 (d)
Other Shares. The registration statement filed pursuant to the request of the Initiating Holders may, subject to the provisions of Section 2.1(e), include Other Shares, and may include securities of the Company being sold for the
account of the Company. 
  
 (e)
Underwriting. If the Initiating Holders intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to this
Section 2.1 and the Company shall include such information in the written notice given pursuant to Section 2.1(a)(i) . In such event, the right of any Holder to include all or any portion of its Registrable Securities in such
registration pursuant to this Section 2.1 shall be conditioned upon such Holder’s participation in an underwriting and the inclusion of such Holder’s Registrable Securities to the extent provided herein. If the Company shall
request inclusion in any registration pursuant to Section 2.1 of securities being sold for its own account, or if other persons shall request inclusion in any registration pursuant to Section 2.1, the Initiating Holders
shall, on behalf of all Holders, offer to include such securities in the underwriting and such offer shall be conditioned upon the participation of the Company or such other persons in such underwriting and the inclusion of the Company’s and
such person’s other securities of the Company and their acceptance of the further applicable provisions of this Section 2 (including Section 2.10). The Company shall (together with all Holders and other persons proposing
to distribute their securities through such underwriting) enter into an underwriting agreement in customary form with the representative of the underwriter or underwriters selected for such underwriting by a majority in interest of the Initiating
Holders, which underwriters are reasonably acceptable to the Company. 
  
 Notwithstanding any other provision of this Section 2.1, if the underwriter determines in good faith that marketing factors require a limitation of the number of shares to be underwritten, the number of shares that may be included in
the underwriting shall be allocated in the following order of priority: first, to the Investor; second, to any other Initiating Holders; third, to the Company for securities being sold for its own account; fourth, to the Major Holder; and fifth, to
any other Holders that have requested inclusion of their shares in the underwriting on a pro rata basis based on the total number of Registrable Securities held by such Holders; provided, however, that no such reduction shall reduce
the amount of securities of the Initiating Holders included in the registration below twenty-five percent (25%) of the total amount of securities 

  

 -5- 

 
included in such registration, unless such offering is the Initial Public Offering and such registration does not include shares of any other Holders, in
which event any or all of the Registrable Securities of the Initiating Holders may be excluded in accordance with the immediately preceding clause; provided, further, that, notwithstanding the any of the foregoing to the contrary, in no event
shall the amount of Registrable Securities of the Investor to be included in such underwriting be reduced until all Registrable Securities held by the Major Holder, by the other Holders and by any Other Selling Stockholders have been first excluded
from the underwriting in their entirety. In no event will shares of any Other Selling Stockholder be included in such registration without the written consent of the Initiating Holder(s) if such inclusion would reduce the number of shares that may
be included by the Initiating Holders. 
  
 If a person who has
requested inclusion in such registration as provided above does not agree to the terms of any such underwriting, such person shall be excluded therefrom by written notice from the Company, the underwriter or the Initiating Holders. The securities so
excluded shall also be withdrawn from registration. Any Registrable Securities or other securities excluded or withdrawn from such underwriting shall also be withdrawn from such registration. If shares are so withdrawn from the registration and if
the number of shares to be included in such registration was previously reduced as a result of marketing factors pursuant to this Section 2.1(e), then the Company shall then offer to all Holders and Other Selling Stockholders who have
retained rights to include securities in the registration the right to include additional Registrable Securities or Other Shares in the registration in an aggregate amount equal to the number of shares so withdrawn, with such shares to be allocated
among such Holders and Other Selling Stockholders requesting additional inclusion, as set forth above. 
  
 2.2 Company Registration.
  
 (a) Company Registration. If the Company shall determine to register any of its securities either for its own account or the
account of a security holder or holders, other than a registration pursuant to Section 2.1 or 2.3, a registration relating solely to employee benefit plans, a registration relating to the offer and sale of debt securities, a
registration relating to a corporate reorganization or other Rule 145 transaction, or a registration on any registration form that does not permit secondary sales, the Company will: 
  
 (i) promptly give written notice of the proposed registration to all Holders; and 
  
 (ii) use its commercially reasonable efforts to include in
such registration (and any related qualification under blue sky laws or other compliance), except as set forth in Section 2.2(b) below, and in any underwriting involved therein, all of such Registrable Securities as are specified in a
written request or requests made by any Holder or Holders received by the Company within ten (10) days after such written notice from the Company is mailed or delivered. Such written request may specify all or a part of a Holder’s
Registrable Securities. 
  
 (b)
Underwriting. If the registration of which the Company gives notice is for a registered public offering involving an underwriting, the Company shall so advise the Holders as a part of the written notice given pursuant to
Section 2.2(a)(i). In such event, the right of any Holder to registration pursuant to this Section 2.2 shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s
Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their securities through such underwriting shall (together with the Company, the Other Selling Stockholders and the other holders of
securities of the Company with registration rights to participate therein distributing their securities through such underwriting) enter into an underwriting 

  

 -6- 

 
agreement in customary form with the representative of the underwriter or underwriters selected by the Company. 
  
 Notwithstanding any other provision of this Section 2.2, if the
underwriters advise the Company in writing that marketing factors require a limitation on the number of shares to be underwritten, the underwriters may (subject to the limitations set forth below) exclude all Registrable Securities from, or limit
the number of Registrable Securities to be included in, the registration and underwriting. The Company shall so advise all holders of securities requesting registration, and the number of shares of securities that are entitled to be included in the
registration and underwriting shall be allocated in the following order of priority: first, to the Company for securities being sold for its own account; second, to the Investor; third, to the Major Holder; and fourth, to any other Holders that have
requested inclusion of their shares in the underwriting on a pro rata basis based on the total number of Registrable Securities held by such Holders; provided, however, that no such reduction shall reduce the amount of securities of
the Holders included in the registration below twenty-five percent (25%) of the total amount of securities included in such registration, unless such offering is the Initial Public Offering and such registration does not include shares of any
Other Selling Stockholders, in which event any or all of the Registrable Securities of the Holders may be excluded in accordance with the immediately preceding clause; provided, further, that, notwithstanding the any of the foregoing to the
contrary, in no event shall the amount of Registrable Securities of the Investor to be included in such underwriting be reduced until all Registrable Securities held by the Major Holder, by the other Holders and by any Other Selling Stockholders
have been first excluded from the underwriting in their entirety. 
  
 If a person who has requested inclusion in such registration as provided above does not agree to the terms of any such underwriting, such person shall also be excluded therefrom by written notice from the Company or the underwriter. The
Registrable Securities or other securities so excluded shall also be withdrawn from such registration. Any Registrable Securities or other securities excluded or withdrawn from such underwriting shall be withdrawn from such registration. 

 
 (c) Right to Terminate Registration. The Company
shall have the right to terminate or withdraw any registration initiated by it under this Section 2.2 prior to the effectiveness of such registration whether or not any Holder has elected to include securities in such registration.

  
 2.3 Registration on Form S-3.
  
 (a) Request for Form S-3 Registration. At any
time after the Company has qualified for the use of Form S-3, in addition to the rights contained in the foregoing provisions of this Section 2 and subject to the conditions set forth in this Section 2.3, if the Company
shall receive from a Holder or Holders of Registrable Securities a written request that the Company effect any registration on Form S-3 or any similar short form registration statement with respect to all or part of the Registrable Securities
(such request shall state the number of shares of Registrable Securities to be disposed of and the intended methods of disposition of such shares by such Holder or Holders), the Company will take all such action with respect to such Registrable
Securities as required by Section 2.1(a)(i) and (ii); provided further that the Company shall keep such registrations effective until the earlier to occur of such time as (i) all Registrable Securities
registered thereunder have been sold, (ii) the Holders whose shares are registered thereon agree to terminate the registration, or (iii) the registration rights of all such Holders terminate. 
  
 (b) Limitations on Form S-3 Registration. The
Company shall not be obligated to effect, or take any action to effect, any such registration pursuant to this Section 2.3: 
  
 (i) In the circumstances described in either Sections 2.1(b)(i) or 2.1(b)(iv); 
  

 -7- 

 (ii) If the Holders, together with the holders of any other securities of the Company
entitled to inclusion in such registration, propose to sell Registrable Securities and such other securities (if any) on Form S-3 at an aggregate price to the public of less than $500,000; or 
  
 (iii) In a given twelve-month period if, during such period,
the Company has already effected one (1) or more registrations pursuant to this Section 2.3. 
  
 (c) Deferral. The provisions of Section 2.1(c) shall apply to any registration pursuant to this
Section 2.3. 
  
 (d)
Underwriting. If the Holders of Registrable Securities requesting registration under this Section 2.3 intend to distribute the Registrable Securities covered by their request by means of an underwriting, the provisions of
Sections 2.1(e) shall apply to such registration. Notwithstanding anything contained herein to the contrary, registrations effected pursuant to this Section 2.3 shall not be counted as requests for registration or
registrations effected pursuant to Section 2.1. 
  
 2.4 Expenses of Registration. All Registration Expenses incurred in connection with registrations pursuant to Sections 2.1, 2.2 and 2.3 hereof shall be borne by the Company. All Selling Expenses relating to
securities registered on behalf of the Holders shall be borne by the holders of securities included in such registration pro rata among each other on the basis of the number of Registrable Securities so registered. 
  
 2.5 Registration Procedures. In the case of each registration
effected by the Company pursuant to Section 2, the Company will keep each Holder advised in writing as to the initiation of each registration and as to the completion thereof. At its expense, the Company will use its commercially
reasonable efforts to: 
  
 (a) Keep such
registration effective for a period of ending on the earlier of the date which is sixty (60) days from the effective date of the registration statement or such time as the Holder or Holders have completed the distribution described in the
registration statement relating thereto. 
  
 (b)
Prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the Securities Act with
respect to the disposition of all securities covered by such registration statement for the period set forth in subsection (a) above; 
  
 (c) Furnish such number of prospectuses, including any preliminary prospectuses, and other documents incident thereto, including any
amendment of or supplement to the prospectus, as a Holder from time to time may reasonably request; 
  
 (d) Use its reasonable best efforts to register and qualify the securities covered by such registration statement under such other
securities or Blue Sky laws of such jurisdiction as shall be reasonably requested by the Holders; provided, that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a
general consent to service of process in any such states or jurisdictions. 
  
 (e) Notify each seller of Registrable Securities covered by such registration statement at any time when a prospectus relating thereto is required to be delivered under the Securities Act of the happening of any event
as a result of which the prospectus included in such registration statement, as then in 

  

 -8- 

 
effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements
therein not misleading or incomplete in light of the circumstances then existing, and following such notification promptly prepare and furnish to such seller a reasonable number of copies of a supplement to or an amendment of such prospectus as may
be necessary so that, as thereafter delivered to the purchasers of such shares, such prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the
statements therein not misleading or incomplete in light of the circumstances then existing; 
  
 (f) Provide a transfer agent and registrar for all Registrable Securities registered pursuant to such registration statement and a CUSIP
number for all such Registrable Securities, in each case not later than the effective date of such registration; 
  
 (g) Cause all such Registrable Securities registered pursuant hereunder to be listed on each securities exchange on which similar
securities issued by the Company are then listed; and 
  
 (h) In connection with any underwritten offering pursuant to a registration statement filed pursuant to Section 2.1 hereof, enter into an underwriting agreement in form reasonably necessary to effect the offer and sale of Common
Stock, provided such underwriting agreement contains reasonable and customary provisions, and provided further, that each Holder participating in such underwriting shall also enter into and perform its obligations under such an agreement.

  
 2.6 Indemnification.
  
 (a) To the extent permitted by law, the Company will
indemnify and hold harmless each Holder, each of its officers, directors and partners, legal counsel, and accountants and each person controlling such Holder within the meaning of Section 15 of the Securities Act, with respect to which
registration, qualification, or compliance has been effected pursuant to this Section 2, and each underwriter, if any, and each person who controls within the meaning of Section 15 of the Securities Act any underwriter, against all
expenses, claims, losses, damages, and liabilities (or actions, proceedings, or settlements in respect thereof) arising out of or based on: (i) any untrue statement (or alleged untrue statement) of a material fact contained or incorporated by
reference in any prospectus, offering circular, or other document (including any related registration statement, notification, or the like) incident to any such registration, qualification, or compliance, (ii) any omission (or alleged omission)
to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or (iii) any violation (or alleged violation) by the Company of the Securities Act, any state securities laws or any rule
or regulation thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any offering covered by such registration, qualification, or compliance, and the Company will reimburse each such
Holder, each of its officers, directors, partners, legal counsel, and accountants and each person controlling such Holder, each such underwriter, and each person who controls any such underwriter, for any legal and any other expenses reasonably
incurred in connection with investigating and defending or settling any such claim, loss, damage, liability, or action; provided that the Company will not be liable in any such case to the extent that any such claim, loss, damage, liability,
or action is caused by any untrue statement or omission based upon written information furnished to the Company by (a) such Holder, or (b) any of such Holder’s officers, directors, partners, legal counsel or accountants, and any
person controlling such Holder, such underwriter or any person who controls any such underwriter and stated to be specifically for use therein; and provided, further that, the indemnity agreement contained in this
Section 2.6(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability, or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld or
delayed). 
  

 -9- 

 (b) To the extent permitted by law, each Holder will, severally and not jointly, if
Registrable Securities held by such Holder are included in the securities as to which such registration, qualification, or compliance is being effected, indemnify and hold harmless the Company, each of its directors, officers, partners, legal
counsel, and accountants and each underwriter, if any, of the Company’s securities covered by such a registration statement, each person who controls the Company or such underwriter within the meaning of Section 15 of the Securities Act,
each other such Holder, and each of their officers, directors, and partners, and each person controlling such Holder, against all claims, losses, damages and liabilities (or actions in respect thereof) caused by: (i) any untrue statement (or
alleged untrue statement) of a material fact contained or incorporated by reference in any such registration statement, prospectus, offering circular, or other document, or (ii) any omission (or alleged omission) to state therein a material
fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse the Company and such Holders, directors, officers, partners, legal counsel, and accountants, persons, underwriters, or control persons
for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability, or action, in each case to the extent, but only to the extent, that such untrue statement (or alleged
untrue statement) or omission (or alleged omission) is made in such registration statement, prospectus, offering circular, or other document in reliance upon and in conformity with written information furnished to the Company by such Holder and
stated to be specifically for use therein; provided, however, that the obligations of such Holder hereunder shall not apply to amounts paid in settlement of any such claims, losses, damages, or liabilities (or actions in respect
thereof) if such settlement is effected without the consent of such Holder (which consent shall not be unreasonably withheld or delayed); and provided that in no event shall any indemnity under this Section 2.6 exceed the net
proceeds from the offering received by such Holder. 
  
 (c) Each party entitled to indemnification under this Section 2.6 (the “Indemnified Party”) shall give notice to the party required to provide indemnification (the “Indemnifying Party”) promptly
after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of such claim or any litigation resulting therefrom; provided that counsel for
the Indemnifying Party, who shall conduct the defense of such claim or any litigation resulting therefrom, shall be approved by the Indemnified Party (whose approval shall not be unreasonably withheld), and the Indemnified Party may participate in
such defense at such party’s expense; and provided further that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Section 2.6,
to the extent such failure is not prejudicial. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement that does
not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation. Each Indemnified Party shall furnish such information regarding
itself or the claim in question as an Indemnifying Party may reasonably request in writing and as shall be reasonably required in connection with defense of such claim and litigation resulting therefrom. 
  
 (d) If the indemnification provided for in this
Section 2.6 is held by a court of competent jurisdiction to be unavailable to an Indemnified Party with respect to any loss, liability, claim, damage, or expense referred to herein, then the Indemnifying Party, in lieu of indemnifying
such Indemnified Party hereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss, liability, claim, damage, or expense in such proportion as is appropriate to reflect the relative fault of the
Indemnifying Party on the one hand and of the Indemnified Party on the other in connection with the statements or omissions that resulted in such loss, liability, claim, damage, or expense as well as any other relevant equitable considerations. The
relative fault of the Indemnifying Party and of the Indemnified Party 

  

 -10- 

 
shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a
material fact relates to information supplied by the Indemnifying Party or by the Indemnified Party and the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission.

  
 (e) Notwithstanding the foregoing, to the
extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into in connection with the underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting
agreement shall control. 
  
 (f) The obligations
of the Company and Holders under this Section 2.6 shall survive the completion of any offering of Registrable Securities in a registration statement under this Section 2, and otherwise. 
  
 2.7 Information by Holder. Each Holder of Registrable Securities shall
furnish to the Company such information regarding such Holder and the distribution proposed by such Holder as the Company may reasonably request in writing and as shall be reasonably required in connection with any registration, qualification or
compliance referred to in this Section 2. 
  
 2.8
Restrictions on Transfer.
  
 (a) The
holder of each certificate representing Registrable Securities by acceptance thereof agrees to comply in all respects with the provisions of this Section 2.8. Each Holder agrees not to make any sale, assignment, transfer, pledge or other
disposition of all or any portion of the Restricted Securities, or any beneficial interest therein, unless and until (x) the transferee thereof has agreed in writing for the benefit of the Company to take and hold such Restricted Securities
subject to, and to be bound by, the terms and conditions set forth in this Agreement, including, without limitation, this Section 2.8 and Section 2.10, except for transfers permitted under Section 2.8(b), and (y):

  
 (i) There is then in effect a registration
statement under the Securities Act covering such proposed disposition and such disposition is made in accordance with such registration statement; or 
  
 (ii) Such Holder shall have given prior written notice to the Company of such Holder’s intention to make such disposition and shall
have furnished the Company with a detailed description of the manner and circumstances of the proposed disposition, and, if requested by the Company, such Holder shall have furnished the Company, at its expense, with (i) an opinion of counsel,
reasonably satisfactory to the Company, to the effect that such disposition will not require registration of such Restricted Securities under the Securities Act (it being understood that an opinion of Woods Rogers PLC shall be deemed satisfactory
with respect to CHS or any permitted transferee of Registrable Securities held by CHS) or (ii) a “no action” letter from the Commission to the effect that the transfer of such securities without registration will not result in a
recommendation by the staff of the Commission that action be taken with respect thereto, whereupon the holder of such Restricted Securities shall be entitled to transfer such Restricted Securities in accordance with the terms of the notice delivered
by the Holder to the Company. It is agreed that the Company will not require opinions of counsel for transactions made pursuant to Rule 144, except in unusual circumstances. 
  
 (b) Permitted transfers include (i) a transfer not involving a change in beneficial ownership, or
(ii) in transactions involving the distribution without consideration of Restricted Securities by 

  

 -11- 

 
any Holder to (x) a parent, subsidiary or other affiliate of Holder that is a corporation, or (y) any of its partners, members or other equity
owners, or retired partners, retired members or other equity owners, or to the estate of any of its partners, members or other equity owners or retired partners, retired members or other equity owners, or (iii) transfers in compliance with
Rule 144(k), as long as the Company is furnished with satisfactory evidence of compliance with such Rule; provided, in each case, that the Holder thereof shall give written notice to the Company of such Holder’s intention to effect
such disposition and shall have furnished the Company with a detailed description of the manner and circumstances of the proposed disposition. 
  
 (c) Each certificate representing Registrable Securities shall (unless otherwise permitted by the provisions of this Agreement) be stamped
or otherwise imprinted with a legend substantially similar to the following (in addition to any legend required under applicable state securities laws): 
  
 THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR UNDER THE
SECURITIES LAWS OF CERTAIN STATES. THESE SECURITIES MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED EXCEPT AS PERMITTED UNDER THE ACT AND APPLICABLE STATE SECURITIES LAWS PURSUANT TO REGISTRATION OR AN EXEMPTION THEREFROM.
THE ISSUER OF THESE SECURITIES MAY REQUIRE AN OPINION OF COUNSEL SATISFACTORY TO THE ISSUER THAT SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION OTHERWISE COMPLIES WITH THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS. 
  
 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
(1) RESTRICTIONS ON TRANSFERABILITY AND RESALE, INCLUDING A LOCK-UP PERIOD OF UP TO 180 DAYS IN THE EVENT OF A PUBLIC OFFERING (SUBJECT TO EXTENSIONS TO COMPLY WITH THE RULES OF THE NATIONAL ASSOCIATION OF SECURITIES DEALERS RELATING TO ANALYST
REPORTS), AS SET FORTH IN AN INVESTOR RIGHTS AGREEMENT, AND (2) VOTING RESTRICTIONS AS SET FORTH IN A RIGHT OF FIRST REFUSAL, CO-SALE AND VOTING AGREEMENT AMONG THE COMPANY AND THE ORIGINAL HOLDERS OF THESE SHARES, COPIES OF WHICH MAY BE
OBTAINED AT THE PRINCIPAL OFFICE OF THE COMPANY. 
  
 The Holders
consent to the Company making a notation on its records and giving instructions to any transfer agent of the Restricted Securities in order to implement the restrictions on transfer established in this Section 2.8. 
  
 (d) The first legend referring to federal and state
securities laws identified in Section 2.8(c) hereof stamped on a certificate evidencing the Restricted Securities and the stock transfer instructions and record notations with respect to such Restricted Securities shall be removed and
the Company shall issue a certificate without such legend to the holder of such Restricted Securities if (i) such securities are registered under the Securities Act, or (ii) such holder provides the Company with an opinion of counsel
reasonably acceptable to the Company to the effect that a public sale or transfer of such securities may be made without registration under the Securities Act, or (iii) such holder provides the Company with 

  

 -12- 

 
reasonable assurances, which may, at the option of the Company, include an opinion of counsel satisfactory to the Company, that such securities can be sold
pursuant to Section (k) of Rule 144 under the Securities Act. 
  
 2.9 Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission that may permit the sale of the Restricted Securities to the public without registration, the Company
agrees to use its commercially reasonable efforts to: 
  
 (a) Make and keep public information regarding the Company available as those terms are understood and defined in Rule 144 under the Securities Act, at all times from and after ninety (90) days following the effective date of the
first registration under the Securities Act filed by the Company for an offering of its securities to the general public; 
  
 (b) File with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the
Exchange Act at any time after it has become subject to such reporting requirements; and 
  
 (c) So long as a Holder owns any Restricted Securities, furnish to the Holder forthwith upon written request a written statement by the
Company as to its compliance with the reporting requirements of Rule 144 (at any time from and after ninety (90) days following the effective date of the first registration statement filed by the Company for an offering of its securities
to the general public), and of the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements), a copy of the most recent annual or quarterly report of the Company, and such other reports and
documents so filed as a Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing a Holder to sell any such securities without registration. 
  
 2.10 Market Stand-Off Agreement. If requested by the Board and any representative of an underwriter of Common
Stock (or other securities) of the Company, Investors and all Stockholders and all holders of options and warrants to purchase Class Common Stock and/or Common Stock (collectively, the “Restricted Holders”), hereby agree that such
Restricted Holder shall not sell or otherwise transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, of any Class Common Stock or Common Stock
(or other securities) of the Company held by such Restricted Holder (other than those included in the registration) during the one hundred eighty (180) day period following the effective date of the Company’s Initial Public Offering filed
under the Securities Act (subject to extensions to comply with the rules of the National Association of Securities Dealers relating to analyst reports), provided that: all officers and directors of the Company and holders of at least one percent
(1%) of the Company’s voting securities are bound by and have entered into similar agreements. The obligations described in this Section 2.10 shall not apply to a registration relating solely to employee benefit plans on
Form S-l or Form S-8 or similar forms that may be promulgated in the future, or a registration relating solely to a transaction on Form S-4 or similar forms that may be promulgated in the future. The Company may impose stop-transfer
instructions and may stamp each such certificate with the second legend set forth in Section 2.8(c) hereof with respect to the shares of Common Stock (or other securities) subject to the foregoing restriction until the end of such one
hundred eighty (180) day period (subject to extensions to comply with the rules of the National Association of Securities Dealers relating to analyst reports). Each Restricted Holder agrees to execute a market standoff agreement with said
underwriters in customary form consistent with the provisions of this Section 2.10. 
  

 -13- 

 2.11 Delay of Registration. No Holder shall have any right to take any action to restrain,
enjoin, or otherwise delay any registration as the result of any controversy that might arise with respect to the interpretation or implementation of this Section 2. 
  
 2.12 Transfer or Assignment of Registration Rights. The rights to cause the Company to register securities
granted to a Holder by the Company under this Section 2 may be transferred or assigned by a Holder only to a transferee or assignee (a) of not less than 750,000 of the Registrable Securities (as presently constituted and subject to
subsequent adjustments for stock splits, stock dividends, reverse stock splits, and the like), (b) that is a partner or retired partner of any Holder that is a partnership, (c) that is a member or former member of any Holder that is a
limited liability company, (d) that is an affiliate of any Holder or (e) that is a family member or trust for the benefit of any individual Holder; provided that (i) such transfer or assignment of Registrable Securities is
effected in accordance with the terms of Section 2.8 hereof, that certain Right of First Refusal, Co-Sale and Voting Agreement by and among the Company, the Investor and other parties thereto dated as of the date hereof (the
“Right of First Refusal, Co-Sale and Voting Agreement”), and applicable securities laws, (ii) the transferee or assignee of such rights assumes in writing the obligations of such Holder under this Agreement, including without
limitation the obligations set forth in Section 2.10, and (iii) with respect to a proposed transfer pursuant to this Section 2.12, the Company is given written notice within 30 days after said transfer or assignment,
stating the name and address of the transferee or assignee and identifying the securities with respect to which such registration rights are intended to be transferred or assigned and such transferee is not, in the Company’s reasonable opinion,
a competitor of the Company or a party who is demonstrably hostile toward the Company. 
  
 2.13 Limitations on Subsequent Registration Rights. From and after the date of this Agreement, the Company shall not, without the prior written consent of Holders of at least a majority of the Registrable
Securities, enter into any agreement with any holder or prospective holder of any securities of the Company giving such holder or prospective holder any registration rights the terms of which are pari passu with or senior to the registration
rights granted to the Holders hereunder. 
  
 2.14 Termination
of Registration Rights. The right of any Holder to request registration or inclusion in any registration pursuant to Section 2.1, 2.2 or 2.3 shall terminate on the earlier of (i) such date, on or after the
closing of the Company’s first registered public offering of Common Stock, on which all shares of Registrable Securities held or entitled to be held upon conversion by such Holder may immediately be sold under Rule 144 in a given ninety
(90) day period, and (ii) such date as all of the Registrable Securities held or entitled to be held upon conversion by such Holder may transferred under Rule 144(k). 
  
 Section 3 
 Covenants of the Company 
  
 The Company
hereby covenants and agrees, as follows: 
  
 3.1 Basic
Financial Information and Inspection Rights.
  
 (a) Basic Financial Information. The Company shall furnish to the Investor, so long as such Investor continues to hold any shares of Class C Common Stock or Class A Common Stock, the following information: 
  
 (i) As soon as practicable after the end of each fiscal year
of the Company, and in any event within ninety (90) days after the end of each such fiscal year of the Company, a consolidated 

  

 -14- 

 
balance sheet of the Company and its subsidiaries, if any, as of the end of such fiscal year, and consolidated statements of income and cash flows of the
Company and its subsidiaries, if any, for such year, prepared in accordance with U.S. generally accepted accounting principles consistently applied and audited by an accounting firm mutually acceptable to the Company and the Investor; and

  
 (ii) As soon as practicable after the end of
the first, second and third quarterly accounting periods in each fiscal year of the Company, and in any event within thirty (30) days after the end of such quarterly accounting periods, an unaudited consolidated balance sheet of the Company and
its subsidiaries, if any, as of the end of each such quarterly period, and unaudited consolidated statements of income and cash flows of the Company and its subsidiaries, if any, for such period, prepared in accordance with U.S. generally accepted
accounting principles consistently applied, subject to changes resulting from normal year-end audit adjustments. 
  
 (b) Supplementary Financial Information. The Company shall furnish to the Investor, so long as such Investor continues to hold any
shares of Class C Common Stock or Class A Common Stock, the following information: 
  
 (i) No later than thirty (30) days prior to the beginning of each fiscal year of the Company, an annual budget and business/operating
plan, with financial projections, approved by the Board; and 
  
 (ii) Any documents primarily relating to Company affairs that have been delivered by the Company to any other stockholders of the Company. 
  
 (c) Tax Matters. The Company at least quarterly shall provide to Investors satisfactory evidence of
the payment of withholding taxes and at least annually provide to the Investor searches from such jurisdiction(s) as the Investor reasonably may request showing that no tax liens have been filed against the Company. 
  
 (d) Litigation Matters. The Company will promptly
provide to the Investor notice of any litigation of material adverse claims, disputes or other actions or proceedings involving the Company. 
  
 3.2 Inspection Rights. The Investor shall have the right, upon reasonable advance notice to the Company and so long as such Investor continues
to hold any shares of Class C Common Stock or Class A Common Stock, to visit and inspect any of the properties of the Company, and to discuss the affairs, finances and accounts of the Company with its officers, and to review such
information as is reasonably requested all during normal business hours. The Company shall make its officers available to the Investor during all such visits and inspections. The Investor agrees to keep, and to use the same degree of care as such
Investor uses to protect its own confidential information, to keep confidential and not misuse any Company information that the Company identifies as being confidential or proprietary (so long as such information is not in the public domain) that is
obtained by such Investor. 
  
 3.3
Confidentiality. The Company shall not be required to comply with any information rights of Section 3 in respect of any Holder whom the Company reasonably determines to be a competitor or an officer, employee, director or
holder of more than ten percent (10%) of a competitor. Each Holder acknowledges that the information received by them pursuant to this Agreement may be confidential and for its use only, and it will not use such confidential information in
violation of the Exchange Act or reproduce, disclose or disseminate such information to any other person (other than its employees or agents having a 

  

 -15- 

 
need to know the contents of such information, and its attorneys), except in connection with the exercise of rights under this Agreement, unless the Company
has made such information available to the public generally. With respect to such confidential information, each Holder agrees to enter into a confidentiality agreement with provisions at least as restrictive as those to which the Company itself is
subject to with respect to such confidential information. Notwithstanding anything herein to the contrary, the Company reserves the right to preclude any Holder from access to any materials or information if the Company believes upon advice of
counsel that such preclusion is reasonably necessary to preserve attorney-client privilege. 
  
 3.4 Use of Proceeds. The Company shall use the proceeds from the sale of the Shares solely for general corporate and working capital purposes and research and development, unless a majority of the Board
approves in good faith and in its reasonable business judgment other uses thereof. 
  
 3.5 Reservation of Common Stock. The Company will at all times reserve and keep available, solely for issuance and delivery upon the conversion of the Class C Common Stock, all Common Stock issuable
from time to time upon such conversion. 
  
 3.6 Protection of
Intellectual Property. The Company shall pursue the protection of all intellectual property, including, but not limited to, the pursuit of all appropriate patents, copyrights and trademarks. 
  
 3.7 Expenses. Each party shall be responsible for their own fees
and expenses associated with the closing of the transaction contemplated by this Agreement. 
  
 3.8 Future Market Standoff Agreements. The Company covenants that all future purchasers of the Company’s securities prior to the Company’s Initial Public Offering will execute a market standoff
agreement in a form substantially similar to the market standoff provision provided in Section 2.10 hereunder. 
  
 3.9 Compensation Committee and Project Evaluation. The Company shall, by amending its Bylaws or otherwise, establish and maintain a
Compensation Committee of the Board (the “Compensation Committee”), which shall consist of not more than three directors elected by the Board, one of which shall be a Class C Director (as such term is defined in the Amended and
Restated Certificate of Incorporation of the Company). The unanimous approval of all standing members of the Compensation Committee, including without limitation the Class C Director, shall be required to effect the following: 
  
 (a) any increase in the annual salary of the senior
executive officers of the Company, including the Chief Executive Officer, the President, the Chief Financial Officer and any Vice-President;

 (c) any payment of one-time bonuses for specific employees; 
  
 (d) any increase in the number of shares of capital stock
reserved and issuable under any Company Plan; or 
  

 -16- 

 (e) any grants of equity incentives (including stock options) to employees, directors,
consultants or any other person or entity pursuant to a Company Plan or otherwise. 
  
 Further, so long as shares of the Company’s Class C Common Stock remain outstanding, the Class C Director shall be entitled to be a member of any committee responsible for evaluation of internal project
investments by the Company or any committee having similar responsibilities. 
  
 3.10 Right of First Review. So long as CHS continues to hold any of the Notes or 750,000 shares of Class C Common Stock or Class A Common Stock (or Common Stock issuable upon the conversion
thereof), and to the extent such technology is not restricted by other contractual arrangements in effect as of August 2, 2005, the Company shall disclose to Carilion Consolidated Laboratory (“CCL”) for review on a confidential
basis, that technology developed now or in the future by the employees of the Company or its affiliates which impacts, or has an application to, the clinical laboratory industry, at least sixty (60) days prior to disclosing such technology to
any third-party for purpose of commercialization. 
  
 3.11
Termination of Covenants. The covenants set forth in this Section 3 (other than the covenants set forth in Section 3.10) shall terminate and be of no further force and effect after the closing of the Company’s
Initial Public Offering. 
  
 Section 4 
 Preemptive Right 
  
 4.1 Preemptive Right. The Company hereby grants to each Holder the preemptive right to purchase (on the same terms and conditions and at the
same price offered to third parties) its pro rata share of New Securities (as defined in Section 4.1(a)) which the Company may, from time to time, propose to sell and issue after the date of this Agreement. A holder’s pro rata
share, for purposes of this right of first refusal, is equal to the ratio of (a) the number of shares of Common Stock owned by such Holder immediately prior to the issuance of New Securities (assuming full conversion of the Shares and exercise
of all outstanding convertible securities, rights, options and warrants, directly or indirectly, into Common Stock held by said Holder) to (b) the total number of shares of Common Stock outstanding immediately prior to the issuance of New
Securities (assuming full conversion of the Shares and exercise of all outstanding convertible securities, rights, options and warrants, directly or indirectly, then outstanding). 
  
 (a) “New Securities” shall mean any capital stock (including Class A Common Stock,
Class B Common Stock and Class C Common Stock) of the Company whether now authorized or not, and rights, convertible securities, options or warrants to purchase such capital stock, and securities of any type whatsoever that are, or may
become, exercisable or convertible into capital stock; provided that the term “New Securities” does not include: 
  
 (i) shares of Class C Common Stock issued or issuable pursuant to the Purchase Agreement and shares of Conversion Stock; 
  
 (ii) shares of Common Stock issued or issuable to officers,
directors and employees of, or consultants or advisors to, the Company or any subsidiary pursuant to any Company Plan approved by the Compensation Committee, or upon exercise of options or warrants granted to such parties pursuant to any such
Company Plan or arrangement; 
  

 -17- 

 (iii) securities issued pursuant to the conversion or exercise of any other outstanding
convertible or exercisable securities as of this date of this Agreement; 
  
 (iv) securities issued or issuable as a dividend or distribution on preferred stock of the Company or pursuant to any event for which adjustment is made pursuant to paragraph 4(e), 4(f), 4(g) or 4(h) of Article V
of the Amended and Restated Certificate of Incorporation of the Company; 
  
 (v) securities offered pursuant to a bona fide Initial Public Offering; 
  
 (vi) securities issued or issuable pursuant to the acquisition of another corporation by the Company by merger, purchase of substantially
all of the assets or other reorganization or pursuant to a joint venture agreement, provided, that such issuances are approved by the Board and Compensation Committee; 
  
 (vii) securities issued or issuable to banks, equipment lessors or other financial institutions pursuant to
a commercial leasing or debt financing transaction approved by the Board; 
  
 (viii) shares of Common Stock issued or issuable in connection with any settlement of any action, suit, proceeding or litigation approved by the Board; 
  
 (ix) securities issued or issuable in connection with sponsored research, collaboration, technology license,
development, OEM, marketing or other similar agreements or strategic partnerships approved by the Compensation Committee and the Board; 
  
 (x) securities issued or issuable to suppliers or third party service providers in connection with the provision of goods or services
pursuant to transactions approved by the Board and Compensation Committee; 
  
 (xi) securities of the Company which are otherwise excluded by the affirmative unanimous vote of the Board; and 
  
 (xii) any right, option or warrant to acquire any security convertible into the securities excluded from the definition of New Securities
pursuant to subsections (i) through (xi) above. 
  
 (b) In the event the Company proposes to undertake an issuance of New Securities, it shall give each Holder written notice of its intention, describing the type of New Securities, and their price and the general terms
upon which the Company proposes to issue the same. Each Holder shall have thirty (30) days after any such notice is mailed or delivered to such Holder (the “Election Period”) to agree to purchase such Holder’s pro rata
share of such New Securities for the price and upon the terms specified in the notice by giving written notice to the Company and stating therein the quantity of New Securities to be purchased. 
  
 (c) In the event the Holders fail to exercise fully the
preemptive right within said Election Period, the Company shall have ninety (90) days thereafter to sell or enter into an agreement (pursuant to which the sale of New Securities covered thereby shall be closed, if at all, within ninety
(90) days from the date of said agreement) to sell that portion of the New Securities with respect to which the Holders’ preemptive right set forth in this Section 4.1 was not exercised, at a price and upon terms no more
favorable to the purchasers thereof than specified in the Company’s notice to Holders delivered pursuant to Section 4.1(b). In the event the Company has not sold within such ninety (90) day period following the 

  

 -18- 

 
Election Period, or such ninety (90) day period following the date of said agreement, the Company shall not thereafter issue or sell any New Securities,
without first again offering such securities to the Holders in the manner provided in this Section 4.1. 
  
 (d) The preemptive right granted under this Agreement shall expire upon, and shall not be applicable to, the Company’s Initial Public
Offering. 
  
 Section 5 
 Miscellaneous 
  
 5.1 Amendment. This Agreement amends and restates the Prior Agreement, and the Prior Agreement is of no further force or effect. Except as
expressly provided herein, neither this Agreement nor any term hereof may be amended, waived, discharged or terminated other than by a written instrument referencing this Agreement and signed by (i) the Company, (ii) the Holders holding a
majority of the Class A Common Stock issued and outstanding, and (iii) the Holders holding a majority of the Class C Common Stock issued pursuant to the Purchase Agreement (excluding any of such shares that have been sold to the
public or pursuant to Rule 144); provided, however, that Holders acquiring shares of Class C Common Stock after the Closing (as defined in the Purchase Agreement) may become parties to this Agreement by executing a
counterpart of this Agreement without any amendment of this Agreement pursuant to this paragraph or any consent or approval of any other Holder. Any such amendment, waiver, discharge or termination effected in accordance with this paragraph shall be
binding upon each Holder and each future holder of all such securities of Holder. Each Holder acknowledges that by the operation of this paragraph, the holders of a majority of the Common Stock issued or issuable upon conversion of the Shares issued
pursuant to the Purchase Agreement (excluding any of such shares that have been sold to the public or pursuant to Rule 144) will have the right and power to diminish or eliminate all rights of such Holder under this Agreement. 
  
 5.2 Notices. All notices and other communications required or
permitted hereunder shall be in writing and shall be mailed by registered or certified mail, postage prepaid, or otherwise delivered by hand or by messenger addressed: 
  
 (a) if to an Investor, at the Investor’s address as shown on Exhibit A hereto or in the
Company’s records, as may be updated in accordance with the provisions hereof 
  
 (b) if to any Holder, at such address as shown in the Company’s records, or, until any such holder so furnishes an address to the
Company, then to and at the address of the last holder of such shares for which the Company has contact information in its records; or 
  
 (c) if to the Company, one copy should be sent to 2851 Commerce Street Southeast, Blacksburg, Virginia 24060, Attn: Chief Executive

 THIS WAREHOUSE AND OFFICE LEASE (“Lease”), made as of this          day of June, 2003 is by and
between Georgia Anne Snyder-Falkinham (“Lessor”) and Luna Innovations, Inc. (“Lessee”), (collectively, “the Parties”). 
  
 :WITNESSETH: 
  
 1. Demised Premises. In consideration of the rents and covenants herein set forth, Lessor does hereby lease to Lessee and Lessee hereby leases from
Lessor the warehouse and office building (containing approximately 14,700 sq. ft.) at 2851 Commerce Street, S.E., Blacksburg, Virginia, for the period of time(s) and upon the terms and conditions hereinafter set forth. 
  
 2. Commencement And Term. The term of this Lease shall commence on the
first day of July, 2003, and terminate at midnight on June 30, 2006 (“Term”), unless renewed as provided for hereinafter. 
  
 3. Rental. Lessee hereby covenants and agrees to pay Lessor as rental for the Leased Premises, which amount shall be payable without deduction,
offset, notice, or demand, ONE HUNDRED FORTY-SEVEN THOUSAND AND NO/100 DOLLARS ($147,000.00) each year during the Term of this Lease, with monthly payments of TWELVE THOUSAND TWO HUNDRED FIFTY AND NO/100 DOLLARS ($12,250.00) being due and payable in
advance on the first day of each month. Payments are to be made to Lessor at 500 South Main Street, Blacksburg, Virginia 24060. As additional rent, Lessee shall be responsible for all janitorial services, water, sewage, and garbage pickup related to
the Leased Premises. Further, Lessee shall pay as additional rent all charges for electricity and natural gas related to the Leased Premises. 
  
 4. Renewal. Lessee shall have the right and option to renew this Lease for an additional period of THREE (3) years, immediately subsequent to
the original Term of this Lease, at a rental rate to be negotiated between the parties in good faith, based upon the economic circumstances and the market conditions then existing. Notice of the exercise of the renewal option shall be given no less
than NINETY (90) days prior to the expiration of the original Term of this Lease. 
  
 5. Late Payment. Lessee hereby covenants and agrees to pay Lessor or agent thereof a late charge of TEN PERCENT (10%) of the amount of any installment of rent or any other sum due Lessor for each late
payment when any installment of rent or any other sum due Lessor under the terms of this Lease is paid more than TEN (10) days after the due date thereof. 
  

6. Use of Leased Premises. Lessee shall use and occupy the Leased Premises, subject to the terms and condition hereof, for the operation of a
fiber optic sensing business and for such other uses as may be customary and incidental thereto. 
  
 7. Utilities and Taxes. The Lessee shall pay promptly all business and personal property taxes, licenses, and bills for utilities (including
telephone) related to the warehouse and office space at 2851 Commerce Street. Lessor shall pay all real estate taxes related to the Leased Premises. 

 8. Maintenance and Repairs. Lessor at her sole expense, within a reasonable time after being
notified in writing by Lessee of the need therefor, shall be responsible for the following: structural repairs to the building; repairs to the roof, gutters, and downspouts; painting of the exterior of the building; maintenance of the yard, hard
surfaced areas, and exterior lighting; as well as repairs to the plumbing, electrical, and HVAC equipment installed by the Lessor; unless the need for such repairs/maintenance is occasioned by the negligent or willful act of Lessee, its agents,
employees, or invitees, in which event such repairs shall be charged to Lessee. All modifications installed by the Lessee shall be the sole responsibility of the Lessee to repair and maintain. 
  
 The Lessee at its sole expense shall provide all other maintenance and make
repairs, including repairs and replacements to the interior finishes necessary to keep the Leased Premises, building and improvements, and equipment in good order and repair. Lessee shall be responsible for keeping the interior of the building neat
and attractive. Snow removal from parking lots and sidewalks shall be the responsibility of the Lessee. Lessee will, at the expiration of the original Term of this Lease or any renewal thereof, deliver up the Leased Premises in as good order and
condition as received, excepting reasonable wear and tear and damage by fire or other casualty of the kind insured against in standard policies of fire insurance with extended coverage. 
  
 Except as provided herein, Lessor shall not be under any obligation to make other repairs to the Leased Premises. Lessor
shall not be chargeable with any liability by reason of negligence or otherwise for not making repairs to the Leased Premises and shall not be liable for any damages (or for any reason whatsoever in connection with the Leased Premises whether caused
by the use of the Leased Premises, water, electricity, heating equipment, or by theft or otherwise) to personal property that the Lessee or assigns or any other person may sustain on or about the Leased Premises. Lessee shall not be entitled to any
reduction in rent, or any claim for damages, by reason of any inconvenience, annoyance, injury to business, or loss of natural light or ventilation arising from any repairs, alternations, or replacements made by Lessor pursuant to this Section.

  
 9. Insurance and Damage to Leased Premises.
(a) The Lessee shall insure at its own expense its property, improvements, inventory, and contents against loss or damage by fire or other hazards. (b) If the building of which the Leased Premises are a part shall be damaged by fire, the
elements, or the casualty, but is not thereby rendered untenantable in whole or in part, Lessor shall promptly, at her own expense, cause such damage to be repaired, and the rent shall not be abated. If by reason of such occurrence the Leased
Premises shall be rendered untenantable only in part, Lessor shall promptly, at her own expense, cause the damage to be repaired and fixed, and the rent shall be abated proportionately to the portion of the Leased Premises rendered untenantable for
such time as may elapse until the whole space is again tenantable. If by reason of such occurrence the Leased Premises shall be rendered wholly untenantable, Lessor shall promptly, at her own expense, cause such damage to be repaired, and the rent
shall be abated in whole until the Leased Premises are restored, unless within SIXTY (60) days after such occurrence Lessor shall give Lessee written notice that she has elected not to reconstruct the destroyed premises. In which event, this
Lease and the tenancy hereby created shall cease as of the day of said occurrence. In no event shall Lessor be responsible for any resulting inconvenience to the Lessee. (c) Notwithstanding the foregoing provisions, if at any time the obligee
of any indebtedness secured by a lien on the Leased Premises shall be obligated to apply all or a substantial part of the proceeds from any insurance to the payment of such indebtedness with the result that the remaining proceeds are insufficient to
pay the cost of 

  

 -2- 

 
making the repairs, restorations, or replacements required hereby and neither the Lessee nor the Lessor agrees to pay such cost, then this Lease shall
terminate THIRTY (30) days after receipt by either the Lessee or the Lessor to the other of written notice of such termination and all remaining proceeds of insurance on the Leased Premises shall be paid to and retained by the Lessor.
(d) Lessee covenants that, without prior written consent of Lessor, it will not do anything which will increase the rate of fire insurance on the building of which the Leased Premises are a part and that, if such consent is given, Lessee will
pay Lessor the amount of the increase in the cost of such insurance as and when the premiums become due. In the event that the Lessee causes an increase in the rate of fire insurance on the building in which the Leased Premises is located, Lessee
covenants and agrees to pay to Lessor the full amount of such rate increase caused by Lessee’s actions. 
  
 10. Condemnation. If the building of which the Leased Premises are a part shall be partially condemned by public authorities under the power of
eminent domain, or purchased in lieu thereof, Lessor shall in no way be responsible for any resulting inconvenience or damage to Lessee, nor shall there be any reduction in the rent unless as a direct result of such occurrence part of such building
shall be rendered untenantable, in which case there shall be a reasonable reduction in rent for such time as may elapse until there be again on the Leased Premises a building of as much value to the Lessee for its use as the one affected by such
occurrence. Lessor shall then proceed to make such repairs and alterations as may be necessary to provide a building of as much value to Lessee as the one existing prior to such occurrence, unless within SIXTY (60) days after the date of such
taking Lessor gives Lessee written notice that she has elected not to reconstruct, repair, or alter such building, in which event this Lease and the tenancy hereby created shall cease as of the day of such taking or sale without any further
liability on the part of either the Lessor and the Lessee to the other. All compensation awarded or paid upon such total or partial taking of the Leased Premises shall belong to and be the property of the Lessor without any participation therein by
the Lessee. In no event shall the Lessor be responsible for any resulting inconvenience to Lessee. 
  
 11. Indemnity to Lessor. Lessee will indemnify and save harmless the Lessor against any and all liability, damage, expense, causes of action,
suits, claims or judgments, and attorney’s fees and costs incurred in connection therewith, arising from injury to persons or property on the Leased Premises or arising by reason of the use of the Leased Premises. Lessee will keep in force at
its own expense so long as this Lease remains in effect broad-form public liability insurance in the amount of $500,000.00 per occurrence and property damage of $100,000.00 per occurrence, or such higher limits as the Lessor may reasonably from time
to time require, protecting and indemnifying Lessee, Lessor, and Lessor’s agents, naming the Lessor as an additional insured against all claims for damage to person or property or for loss of life or property occurring on, in, or about the
Leased Premises. Such certificates of insurance and any endorsement thereto shall be furnished to Lessor by Lessee at or prior to the commencement of the original Term of this Lease and thereafter at least TEN (10) days prior to the expiration
of any such policy. Each such policy shall provide for at least TEN (10) days’ written notice to Lessor of any change or cancellation thereof. 
  
 12. Assignment and Subletting. During the original Term hereof or any renewal hereof, the Lessee shall not have the right to assign this Lease or
to sublet or to permit any other person to occupy the Leased Premises, or any part thereof, except with the prior written consent of the Lessor, which consent shall not be unreasonably withheld. No such assignment or subletting, whatever, shall
relieve the Lessee, or any guarantor of Lessee’s obligations hereunder, of its/their obligations 

  

 -3- 

 
hereunder. For any such assignment or sublease, Lessee shall pay all cost (including legal fees) incurred by Lessor. 
  
 13. Default. All items of indebtedness or damages which may become
owing to the Lessor by the Lessee under the covenants and provisions hereof shall be considered as items of rent, and the Lessor shall have the same liens and the same remedies for the collection thereof as are provided herein and by law for the
collection of rent. Lessee covenants and agrees to pay interest at the rate of TWELVE PERCENT (12%) per annum on all rents or other sums accrued if not paid when due, Lessor expressly reserving all other rights and remedies provided herein and
by law in respect thereto. If the Lessee shall default in the performance of any of the covenants and conditions contained in this Lease, the Lessor may, but shall not be obligated to, cure any such default and add the cost thereof, with interest at
the rate of TWELVE PERCENT (12%) per annum, to the amount of the next installment of rent to be paid by the Lessee hereunder, but it is expressly agreed that such curing of any default or payment of any indebtedness by the Lessor shall not be
deemed a waiver or release of any default hereunder or of any remedy provided herein. In addition, upon the breach of any covenants, term, condition, or provision herein contained, or the repudiation of this Lease by the Lessee, or the failure of
the Lessee to occupy the Leased Premises at the beginning of the Term, or the abandonment or vacation of Leased Premises by the Lessee, or the Lessee’s (or any guarantor of this Lease) being adjudicated as bankrupt, or the insolvency of Lessee,
or the appointment of a Receiver or Trustee of the Lessee’s property, or upon the business conducted on the Leased Premises being substantially terminated at any time, the total rent herein identified, whether accrued or not, shall at the
option of Lessor immediately become due and payable, and the Lessor shall have the right to enter the Leased Premises at once, by force or otherwise, and to remove any property therein without liability for damage thereto, and without obligation to
store such property, and without being liable to any prosecution therefore, and to distrain for rent, and also to re-rent the Leased Premises as agent for the Lessee for the unexpired portion of the Term and to receive the rent and to apply the
same, after deduction of appropriate expenses, to the payment of the rent payable hereunder, Lessee remaining liable for any deficiency; or the Lessor may, at her option, immediately terminate this Lease. In the event of termination, Lessee shall
quit and surrender the Leased Premises to the Lessor, providing that neither terminating this Lease under this clause nor recovering possession of the Leased Premises shall deprive the Lessor of any other action or remedy against the Lessee for
possession, for rent, or for damages. All of Lessor’s rights shall be cumulative and shall not preclude the Lessor from exercising all other rights and remedies provided by law. 
  
 14. Waiver of Subrogation. Any other provision hereof notwithstanding, but subject to the consent of Lessor’s
and Lessee’s insurance carriers, it is understood and agreed that, in the event of any loss or damage to the Leased Premises by fire or any other perils insured customarily under extended coverage portions of fire or other insurance policies,
regardless of the cause thereof, and whether or not the same be caused by carelessness or negligence of the Lessor or Lessee, their servants, employees, agents, visitors, or licensees, neither the Lessee or Lessor nor their insurance carriers shall
have any right of subrogation against the Lessee or Lessor, their servants, employees, agents, visitors, or licensees for any such damage or loss so sustained. Lessor and Lessee agree to apply to their respective insurance carriers for a policy
rider consenting to the foregoing waiver of subrogation provisions. 
  

 -4- 

 15. Improvements. Any improvements or changes, including enlargements, to the Leased Premises
shall be made at the expense of the Lessee. Before making any alterations or improvements, the written consent of the Lessor shall be first obtained, which consent shall not be unreasonably withheld. All repairs, improvement, replacements, or
alterations to the Leased Premises, including without limitations all electric wiring, electric fixtures, plumbing, floor coverings (including carpeting, but excepting rugs), heating and air conditioning systems, shall be deemed to be part of the
realty and shall become the property of the Lessor at the termination of this Lease, except those expressly agreed in writing to not be part of the reality, and shall not be removed at the expiration or earlier termination of this Lease unless
removal is requested by Lessor, in which event Lessee agrees to do so and to repair promptly any damage caused by such removal. No improvements or changes shall be made without obtaining all necessary permits. 
  
 16. Removal Upon Termination. Lessee shall at the end of this Lease or
any renewal or extension, or sooner termination thereof, remove from the Leased Premises any ashes, dirt, rubbish, or any refuse matter and leave each room clean. Provided Lessee is not in default hereunder, Lessee shall have the right to remove any
of its trade fixtures from the Leased Premises providing it repairs any damages by such removal. All goods and property on the Leased Premises left after Lessee’s removal shall be liable to distress and may be distrained and sold for any rent
in arrears or cost of repairs to the Leased Premises or fixtures thereof made necessary by misuse or neglect on the part of the Lessee or cost of removing rubbish, refuse matter, or anything else found upon the Leased Premises. 
  
 17. Signs. Lessee, at its sole expense, may attach to the building and
maintain on the Leased Premises a neat and appropriate sign advertising its business as it shall desire, provided the size, color, style, and method of lighting is acceptable to Lessor, further provided that the Lessee complies with all applicable
governmental ordinances and regulations and that written permission is first obtained from Lessor. Lessee will not place or suffer to be placed or maintained any fixture, awning, or canopy or any decoration, lettering, or advertising matter on any
exterior wall or on the glass of any window or door of the Leased Premises. In the event of the violation of the foregoing by the Lessee, Lessor may remove such fixture, awning, canopy, sign, decorating advertising, or lettering without any
liability and may charge for expenses incurred by such removal to the Lessee. Lessee shall keep any such sign freshly painted and in good repair at all times. Upon the termination of this Lease, Lessee shall remove such sign and repair any damages
to the Leased Premises caused by the erection, maintenance, and removal of such sign. 
  
 The Lessor shall have the right to prescribe the general type of window treatment (draperies, curtains, blinds, etc.) which are to be used by Lessee, and Lessee shall place no curtains, draperies, or blinds in the
windows without prior consultation with and approval by Lessor, which approval shall not be unreasonably withheld. 
  
 18. Covenant and Agreement of Lessor. Lessor covenants and agrees that Lessee, upon paying the rental herein reserved and upon the performance of
the covenants, conditions, and agreements herein provided to be observed and performed by Lessee, shall peaceably, and quietly hold and enjoy the Leased Premises for and during the Term hereof and any extension thereof. 
  

 -5- 

 19. Waiver of Homestead Exemption and Attorney’s Fees. Lessee and any guarantor of
Lessee’s obligation hereunder hereby expressly waive the benefit of the homestead exemption laws of the State of Virginia as to all obligations hereunder. The Lessee and any such guarantor hereby agree to pay all expenses and costs incurred by
Lessor pertaining thereto and in enforcement of any remedy available to Lessor and attorney’s fees of TWENTY-FIVE PERCENT (25%) of any amount due by Lessee, or a reasonable attorney’s fees in the event that no amount is due, if the
Lessor employs the services of an attorney to enforce the performance of the covenants hereof by the Lessee, to evict the Lessee, to collect money due by the Lessee, or to perform any services based upon Lessee’s default in the performance of
any covenants of this Lease. 
  
 20. Security Deposit.
Lessor herewith acknowledges receipt from Lessee of TWO THOUSAND TWO HUNDRED THIRTY AND NO/100 DOLLARS ($2,230.00), which Lessor is to retain, without liability or interest, as security for the faithful performance of all the covenants, conditions,
and agreements of this Lease, but in no event shall the Lessor be obligated to apply the same to rents or other charges in arrears or to damages due to the Lessee’s failure to perform the said covenants, conditions, and agreements. Lessor may
apply this security at her option; and Lessor’s right to possession of the Leased Premises for nonpayment of rent or for any other reason, or to exercise any other right or remedy to which Lessor may be entitled hereunder or in law or equity,
shall not in any event be affected by reason of the fact that the Lessor holds this security or has applied the same as aforesaid. If, without termination of this Lease, the security shall have been reduced, by application towards rents or
otherwise, below the sum stated above, Lessee upon demand shall immediately deposit with Lessor the amount of the difference to be held as security hereunder. The same security, if not applied toward payment of the rent in arrears or toward payment
of damages suffered by the Lessor by reason of the Lessee’s breach of the covenants, conditions, or agreements of this Lease is to be returned to the Lessee when this Lease is terminated, according to these terms. In no event is the said
security to be returned until the Lessee has properly cleaned and vacated the premises and delivered possession to the Lessor. In the event that the Lessor repossesses said premises because of the Lessee’s default or because of the
Lessee’s failure to carry out the covenants, conditions, and agreements of this Lease, Lessor may apply the said security on all damages up to such damages as may be suffered or shall accrue thereafter by reason of the Lessee’s default or
breach. 
  
 21. Miscellaneous Covenants of Lessee. Lessee
covenants that it will comply with all Federal, State, and/or municipal laws, ordinances, and regulations relating to its business conducted in the Leased Premises and to its use of the Leased Premises; that it will not use, or permit to be used,
the Leased Premises for any illegal or immoral purpose; that it will not use the sidewalks for business purposes, that it will not, without prior written consent of the Lessor, use or permit to be used any advertising medium or device such as
phonographs, radio, or public address system to hold a fire, bankruptcy, going out-of-business or auction sale; and that it will permit Lessor or its representatives (i) to enter the Leased Premises at any reasonable time for purposes of making
inspections and/or repairs and, during the last TWELVE (12) months of the Term, for the purpose of exhibiting the Leased Premises to prospective tenants and (ii) to place a “For Rent” sign in a front window during such period of
time. 
  
 22. Security/Alarm System. The Lessee may, at its
sole expense, install a security/alarm system at the Leased Premises. 
  

 -6- 

 23. Notices. All notices required or permitted to be given under this Lease shall be in writing
and shall be sent by registered or certified mail addressed to Lessor at 500 South Main Street, Blacksburg, Virginia 24060, and to Lessee at 2851 Commerce Street, S.E., Blacksburg, Virginia 24060, or at such other address as either Lessor or Lessee
shall designated in the manner herein set forth for giving of the notice. Any such notice shall be deemed to have been given at the time it is postmarked by the Untied States Postal service. Lessee will surrender all keys at the termination of this
Lease or pay the cost of replacing all locks for the Leased Premises. 
  
 24. Miscellaneous. (a) This Lease Agreement may be executed by the Lessor and the Lessee in any number of counterparts (each of which shall be deemed a single instrument), merges all understandings and agreement between the
parties hereto with respect to the Leased Premises, and shall constitute the entire Lease Agreement. (b) The failure to insist, in any one or more instances, upon strict performance of any of the covenants of this Lease, or to exercise any
option herein contained, shall not be construed as a waiver or a relinquishment for the future of such covenants or option, but the same shall continue and remain in full force and effect. The receipt by the Lessor of rent with knowledge of the
breach of any covenant hereof shall not be deemed a waiver of such a breach, and no waiver by the Lessor of any provision hereof shall be deemed to have been made unless expressed in writing and signed by the parties so charged with the waiver.
(c) This Lease and the covenants and conditions herein contained shall inure to the benefit and be binding upon the Lessor and the Lessee and their respective successors and their permitted assigns. (d) This Lease shall be governed by the
construed in accordance with the laws of the State of Virginia. (e) Masculine and/or feminine pronouns are to be substituted for those of the neuter form and the plural is to be substituted for the singular number of any place or places herein
in which the context may require such substitution. (f) The headings of the Sections herein are inserted for convenience only and shall not control or affect the meaning or construction of any of the provisions of this Lease. (g) Both
Lessor and Lessee represent and warrant that there are no claims for brokerage commissions or finders’ fees in connection with the execution of this Lease. 
  

25. Subordination. Lessee agrees that this Lease, and all the rights included herein, shall be subordinate to the rights of any existing or
subsequently created mortgage or deed of trust placed upon the Leased Premises by Lessor or other fee owner of the Leased Premises. 
  
 26. Mortgage Protection. Lessee agrees to give any mortgagees and/or trust deed holders, by Registered Mail, a copy of any Notice of Default served
upon the Lessor, provided that prior to such notice Lessee has been notified in writing (by way of Notice of Assignment of Rents and Leases or otherwise) of the address of such mortgages and/or trust deed holders. Lessee further agrees that if
Lessor shall have failed to cure such default within the time provided in this Lease, then the mortgages and/or trust deed holders shall have an additional THIRTY (30) days within which to cure such default. If such default cannot be cured
within that time, then such additional time as may be necessary to cure such default shall be granted if within such THIRTY (30) days any mortgagee and/or trust deed holder has commenced and is diligently pursuing the remedies necessary to cure
such default (including but not limited to commencement of foreclosure proceedings, if necessary to effect such cure), in which event this Lease shall not be terminated while such remedies are being diligently pursued.
