REGISTRATION RIGHTS

 

2.1     Notice
of Registration. If at any time or from time to time the Company shall determine to register any of its Common Stock, either
for its own account or the account of security holders, other than (i) a registration on Form S-8 or otherwise relating solely
to employee benefit plans, (ii) a registration on Form S-4, (iii) a registration on any other form which does not permit secondary
sales, or (iv) a registration on any other form which does not include substantially the same information as would be required
to be included in a registration statement covering the sale of the Registrable Securities, the Company shall:

 

(a)     promptly
give to each Holder written notice thereof; and

 

(b)     except
as set forth in Section 2.3 or required by applicable law or the Securities and Exchange Commission, include in such registration
(and any related qualification under blue sky laws or other compliance), and in any underwriting involved therein, all Registrable
Securities as are specified in a written request or requests, actually received by the Company within 10 business days after receipt
of such written notice from the Company, by any Holder.

 

2.2     Selling
Stockholder Questionnaire. Each Holder desiring to have its Registrable Securities included in a Registration Statement under
this Article II agrees to furnish to the Company a completed selling stockholder questionnaire in the form attached as Schedule
2.2 (the “Selling Stockholder Questionnaire”) within 10 business days after receipt by such Holder of the
written notice specified in Section 2.1(b) from the Company. The Company shall notify a Holder if it requires additional information
from that Holder other than the information contained in the Selling Stockholder Questionnaire, which additional information shall
be completed and delivered to the Company promptly following such request. Each Holder further agrees that it shall not be entitled
to be named as a selling security holder in the Registration Statement or use the Prospectus for offers and resales of Registrable
Securities at any time, unless such Holder has returned to the Company a completed and signed Selling Stockholder Questionnaire
and a response to any requests for further information as described in the previous sentence. If a Holder of Registrable Securities
returns a Selling Stockholder Questionnaire or a request for further information, in either case, after its respective deadline,
the Company shall use its commercially reasonable efforts at the expense of the Holder who failed to return the Selling Stockholder
Questionnaire or to respond for further information to take such actions as are required to name such Holder as a selling security
holder in the Registration Statement or any pre-effective or post-effective amendment thereto and to include (to the extent not
theretofore included) in the Registration Statement the Registrable Securities identified in such late Selling Stockholder Questionnaire
or request for further information. Each Holder acknowledges and agrees that the information in the Selling Stockholder Questionnaire
or request for further information as described in this Section 2.2 will be used by the Company in the preparation of the
Registration Statement and hereby consents to the inclusion of such information in the Registration Statement.

 

    	 

    	 

    

 

2.3     Underwritten
Offerings. 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 2.1. In such event the
right of any Holder to registration pursuant to Section 2.1 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 and the
other holders distributing their securities through such underwriting) enter into an underwriting agreement in customary form with
the managing underwriter selected for such underwriting by the Company. The foregoing shall include, without limitation, such powers
of attorney and escrow agreements as the underwriters may require. Notwithstanding any other provision of this Article II,
if the managing underwriter determines that marketing factors require a limitation of the number of shares to be underwritten,
the managing underwriter may limit the Registrable Securities to be included in such registration, it being understood that the
shares proposed to sold by the Company in such underwriting shall be given priority and shall not be subject to any such limitation
vis-a-vis the Registrable Securities. The Company shall so advise all Holders and other holders distributing their securities through
such underwriting, and the number of shares of Registrable Securities that may be included in the registration and underwriting
shall be allocated among all Holders and such other holders in proportion, as nearly as practicable, to the respective amounts
of Registrable Securities held by such Holders and such other holders at the time of filing the registration statement. To facilitate
the allocation of shares in accordance with the above provisions, the Company may round the number of shares allocated to any Holder
to the nearest 100 shares. If any Holder disapproves of the terms of any such underwriting, such Holder may elect to withdraw therefrom
by written notice to the Company and the managing underwriter.

 

The Registrable Securities
so excluded or withdrawn shall also be excluded or withdrawn from registration, and neither such Registrable Securities nor any
securities convertible into or exchangeable or exercisable for Common Stock shall be sold in any public sale or other distribution,
without the prior written consent of the Company or such underwriters, for such period of time before and after (not to exceed
thirty (30) days before and one hundred eighty (180) days after) the effective date of the registration statement relating thereto
as the underwriters may require.

 

2.4     Company
Termination of Registration. The Company reserves the right to terminate any registration under this Article II at any
time and for any reason without liability to any Holder.

 

    	 

    	 

    

 

 

ARTICLE

Registration Procedures

 

3.1     Registration
Procedures. If and whenever the Company is required by the provisions of Article II hereof to effect the registration
of any Registrable Securities under the Securities Act, the Company will, as expeditiously as possible:

 

(a)     prepare
and file with the Commission a Registration Statement with respect to such Registrable Securities, respond as promptly as possible
to any comments received from the Commission, and use its commercially reasonable efforts to cause such Registration Statement
to become and remain effective for the Effectiveness Period with respect thereto, and the Investor
shall have the opportunity to object to any information pertaining to itself that is contained
therein and the Company will make the corrections reasonably requested by the Investor with
respect to such information prior to filing any Registration Statement or amendment thereto or any Prospectus or any supplement
thereto;

 

(b)     prepare
and file with the Commission such amendments and supplements to such Registration Statement and the Prospectus used in connection
therewith as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all Registrable
Securities covered by such Registration Statement and to keep such Registration Statement effective until the expiration of the
Effectiveness Period applicable to such Registration Statement;

 

(c)     furnish
to the Investor such number of copies of the Registration Statement and the Prospectus included therein (including each preliminary
Prospectus and any amendments and supplements to the Registration Statement and the Prospectus) and such other documents as the
Investor reasonably may reasonably request to facilitate the public sale or disposition of the Registrable Securities covered by
such Registration Statement;

 

(d)     use its
commercially reasonable efforts to register or qualify the Investor’s Registrable Securities covered by such Registration
Statement under the securities or “blue sky” laws of such jurisdictions within the United States as the Investor may
reasonably request and do any and all other acts and things which may be reasonably necessary or advisable to enable the Investor
to consummate the disposition in such jurisdiction of the Registrable Securities, provided, however, that the Company shall not
for any such purpose be required to qualify generally to transact business as a foreign corporation in any jurisdiction where it
is not so qualified or to consent to general service of process in any such jurisdiction;

 

(e)     list the
Registrable Securities covered by such Registration Statement with any securities exchange on which the Common Stock of the Company
is then listed; and

 

(f)     immediately
notify the Investor 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 contained in such Registration Statement, as then in 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, and, at the request of the Investor, the Company shall prepare a supplement or amendment to
such Prospectus so that, as thereafter delivered to the purchasers of Registrable Securities, such Prospectus shall not contain
an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the
statement therein not misleading.

foregoing shall occur.

 

4.2     Selling
Expenses. All customary and reasonable underwriting discounts and selling commissions applicable to the sale of Registrable
Securities, and any fees and disbursements of any counsel to the Holders (collectively, the “Selling Expenses”)

ARTICLE
V

Indemnification.

 

5.1     Company
Indemnification. In the event of a registration of any Registrable Securities under the Securities Act pursuant to this
Agreement, the Company shall indemnify and hold harmless each Holder, and its officers, directors and each other person, if any,
who controls such Holder within the meaning of the Securities Act, against any losses, claims, damages or liabilities, joint or
several, to which such Holder, or such persons may become subject under the Securities Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of any material fact contained in any Registration Statement under which such Registrable Securities were registered
under the Securities Act pursuant to this Agreement, any preliminary Prospectus or final Prospectus contained therein, or any amendment
or supplement thereof, or arise out of or are based upon the 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 any violation or alleged violation by the Company
of the Securities Act, the Exchange Act or applicable “blue sky” laws, and shall reimburse such Holder, and each such
person for any legal or other expenses incurred by them in connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the Company shall not be liable in any such case if and to the extent that any such
loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or
alleged omission so made in conformity with information furnished in writing and executed by or on behalf of a Holder specifically
for use in any such document.

 

    	 

    	 

    

 

5.2     Holder
Indemnification. Each Holder of Registrable Securities included in a Registration Statement pursuant to this Agreement shall
indemnify and hold harmless the Company, and its officers, directors and each other person, if any, who controls the Company within
the meaning of the Securities Act, against all losses, claims, damages or liabilities, joint or several, to which the Company or
such persons may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon any untrue statement of any material fact which was furnished in writing
and executed by the Investor to the Company expressly for use in (and such information is contained in) the Registration Statement
under which such Registrable Securities were registered under the Securities Act pursuant to this Agreement, any preliminary Prospectus
or final Prospectus contained therein, or any amendment or supplement thereof, or arise out of or are based upon the omission to
state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and shall
reimburse the Company and each such person for any reasonable legal or other expenses incurred by them in connection with investigating
or defending any such loss, claim, damage, liability or action; provided, however, that a Holder shall be liable in any such case
if and only to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or
omission so made in conformity with information furnished in writing to the Company and executed by or on behalf of such Holder
specifically for use in any such document. Notwithstanding the provisions of this paragraph, a Holder shall not be required to
indemnify any person or entity in excess of the amount of the aggregate net proceeds received by the Holder in respect of Registrable
Securities in connection with any such registration under the Securities Act.

 

5.3     Indemnification
Procedures. Promptly after receipt by a party entitled to claim indemnification hereunder (an “Indemnified Party”)
of notice of the commencement of any action, such Indemnified Party shall, if a claim for indemnification in respect thereof is
to be made against a party hereto obligated to indemnify such Indemnified Party (an “Indemnifying Party”), promptly
notify the Indemnifying Party in writing thereof, but the delay or omission so to notify the Indemnifying Party shall not relieve
it from any liability which it may have to such Indemnified Party other than under this Section 5.3 and shall only relieve
it from any liability which it may have to such Indemnified Party under this Section 5.3 if and to the extent the Indemnifying
Party is prejudiced by such omission or delay of such notification. In case any such action shall be brought against any Indemnified
Party and it shall notify the Indemnifying Party of the commencement thereof, the Indemnifying Party shall be entitled to participate
in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such Indemnified
Party, and, after notice from the Indemnifying Party to such Indemnified Party of its election so to assume and undertake the defense
thereof, the Indemnifying Party shall not be liable to such Indemnified Party under this Section 5.3 for any legal expenses
subsequently incurred by such Indemnified Party in connection with the defense thereof; if the Indemnified Party retains its own
counsel, then the Indemnified Party shall pay all fees, costs and expenses of such counsel; provided, however, that, if the defendants
in any such action include both the Indemnified Party and the Indemnifying Party and the Indemnified Party shall have reasonably
concluded that there may be reasonable defenses available to it which are different from or additional to those available to the
Indemnifying Party or if the interests of the Indemnified Party reasonably may be deemed to conflict with the interests of the
Indemnifying Party, the Indemnified Party shall have the right to select one separate counsel and to participate in such legal
defenses, with the reasonable expenses and fees of such separate counsel and other reasonable expenses related to such participation
to be reimbursed by the Indemnifying Party as incurred.

 

    	 

    	 

    

 

5.4     Contribution.
In order to provide for just and equitable contribution in the event of joint liability under the Securities Act in any case in
which either (i) a Holder, or any officer, director or controlling person of a Holder, makes a claim for indemnification pursuant
to this Section 5.4 but it is judicially determined (by the entry of a final judgment or decree by a court of competent
jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not
be enforced in such case notwithstanding the fact that this Section 5.4 provides for indemnification in such case, or (ii)
contribution under the Securities Act may be required on the part of the Investor or such officer, director or controlling person
of the Investor in circumstances for which indemnification is provided under this Section 5.4; then, and in each such case,
the Company and the Investor shall contribute to the aggregate losses, claims, damages or liabilities to which they may be subject
(after contribution from others) in such proportion so that the Investor is responsible only for the portion represented by the
percentage that the public offering price of its securities offered by the Registration Statement bears to the public offering
price of all securities offered by such Registration Statement, provided, however, that, in any such case, no person guilty of
fraudulent misrepresentation (within the meaning of Section 10(f) of the Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

 

5.5     Survival.
The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made
by or on behalf of the indemnified party or any officer, director or controlling Person of such indemnified party and shall survive
the transfer of securities.

 

ARTICLE
VI

Miscellaneous.

 

6.1     Compliance.
Each Holder covenants and agrees that it shall comply with the prospectus delivery requirements of the Securities Act as applicable
to it in connection with sales of Registrable Securities pursuant to any Registration Statement.

 

    	 

    	 

    

 

6.2     Discontinued
Disposition. Each Holder agrees by its acquisition of Registrable Securities that, upon receipt of a notice from the Company
of the occurrence of a Discontinuation Event (as defined below), such Holder shall forthwith discontinue disposition of such Registrable
Securities under the applicable Registration Statement until such Holder’s receipt of the copies of the supplemented Prospectus
and/or amended Registration Statement or until it is advised in writing by the Company that the use of the applicable Prospectus
may be resumed, and, in either case, has received copies of any additional or supplemental filings that are incorporated or deemed
to be incorporated by reference in such Prospectus or Registration Statement. The Company may provide appropriate stop orders to
enforce the provisions of this Section 6.2. For purposes of this Agreement, a “Discontinuation Event”
shall mean (i) when the Commission notifies the Company whether there will be a “review” of such Registration Statement
and whenever the Commission comments in writing on such Registration Statement (the Company shall provide true and complete copies
thereof and all written responses thereto to each of the Holders); (ii) any request by the Commission or any other Federal or state
governmental authority for amendments or supplements to such Registration Statement or Prospectus or for additional information;
(iii) the issuance by the Commission of any stop order suspending the effectiveness of such Registration Statement covering any
or all of the Registrable Securities or the initiation of any Proceedings for that purpose; (iv) the receipt by the Company of
any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable
Securities for sale in any jurisdiction, or the initiation or threatening of any Proceeding for such purpose; and/or (v) receipt
of notice of the occurrence of any event or passage of time that makes the financial statements included in such Registration Statement
ineligible for inclusion therein or any statement made in such Registration Statement or Prospectus or any document incorporated
or deemed to be incorporated therein by reference untrue in any material respect or that requires any revisions to such Registration
Statement, Prospectus or other documents so that, in the case of such Registration Statement or Prospectus, as the case may be,
it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

 

6.3     Transfer
of Registration Rights. The rights to cause the Company to register securities granted to Holders under Article II may
be assigned to a transferee or assignee in connection with any transfer or assignment of Registrable Securities by a Holder, provided
that: (i) such transfer may otherwise be effected in accordance with applicable securities laws, (ii) such transferee agrees in
writing to be bound by the terms of this agreement and (iii) written notice thereof is promptly given to the Company.

 

6.4     Entire
Agreement. This Agreement sets forth the entire agreement of the parties with respect to the subject matter hereof. No provision
of this Agreement may be explained or qualified by any prior or contemporaneous understanding, negotiation, discussion, conduct,
or course of conduct or by any trade usage, and, except as otherwise expressly stated herein, there is no condition precedent to
the effectiveness of any provision hereof. No party has relied on any representation, warranty, or agreement of any person in entering
this Agreement, except those expressly stated herein.

 

6.5     Counterparts;
Facsimile Signatures. This Agreement may be executed in counterparts, each of which shall constitute an original, but
all of which shall constitute one agreement. This Agreement shall become effective upon delivery to each party of an executed counterpart
or the earlier delivery to each party of original, photocopied, or electronically transmitted signature pages that together (but
need not individually) bear the signatures of all other parties.

 

6.6     Amendments;
Waivers; Remedies.

 

(a)     This Agreement
cannot be amended, except by a writing signed by each party, or terminated orally or by course of conduct. No provision hereof
can be waived, except by a writing signed by the party against whom such waiver is to be enforced, and any such waiver shall apply
only in the particular instance in which such waiver shall have been given. Notwithstanding the foregoing, a waiver or consent
to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of certain Holders and that
does not directly or indirectly affect the rights of other Holders may be given by Holders of at least a majority of the Registrable
Securities to which such waiver or consent relates; provided, however, that the provisions of this sentence may not be amended,
modified, or supplemented except in accordance with the provisions of the immediately preceding sentence.

 

    	 

    	 

    

 

(b)     Neither
any failure or delay in exercising any right or remedy hereunder or in requiring satisfaction of any condition herein nor any course
of dealing shall constitute a waiver of or prevent any party from enforcing any right or remedy or from requiring satisfaction
of any condition. No notice to or demand on a party waives or otherwise affects any obligation of that party or impairs any right
of the party giving such notice or making such demand, including any right to take any action without notice or demand not otherwise
required by this Agreement. No exercise of any right or remedy with respect to a breach of this Agreement shall preclude exercise
of any other right or remedy, as appropriate to make the aggrieved party whole with respect to such breach, or subsequent exercise
of any right or remedy with respect to any other breach.

 

(c)     Except
as otherwise expressly provided herein, no statement herein of any right or remedy shall impair any other right or remedy stated
herein or that otherwise may be available.

 

(d)     Notwithstanding
anything else contained herein, neither shall any party seek, nor shall any party be liable for, punitive or exemplary damages,
under any tort, contract, equity, or other legal theory, with respect to any breach (or alleged breach) of this Agreement or any
provision hereof or any matter otherwise relating hereto or arising in connection herewith.
