(a) Registration Statement.



(i) The Company shall use commercially reasonable efforts to
comply with the reporting requirements of Section 13 or 15(d) of the Exchange Act promptly following the closing of the purchase and sale of the securities contemplated by the Purchase Agreement. Promptly following the date (the Reporting
Date) upon which the Company is again in compliance with such reporting requirements but in any event not later than forty-five (45) days following the Reporting Date (the Filing Deadline), the Company shall use commercially
reasonable efforts to file with the SEC a registration statement on Form S-1 covering all Registrable Securities in an amount at least equal to the number of Shares plus the number of shares of Common Stock necessary to permit the exercise in full

covering the Registrable Securities (or a post-effective amendment on Form S-3 to the registration statement on Form S-1) (a Shelf Registration Statement) and shall use commercially reasonable efforts to cause such Shelf Registration

(b) Expenses. The Company will pay all expenses associated with each registration, including filing and printing fees, counsel and accounting fees and expenses, costs associated with clearing the Registrable Securities for sale
under applicable state securities laws and listing fees, but excluding fees and expenses of counsel to the Investors, discounts, commissions, fees of underwriters, selling brokers, dealer managers or similar securities industry professionals with

the securities covered thereby.



(ii) For not
more than twenty (20) consecutive days or for a total of not more than forty-five (45) days in any twelve (12) month period, the Company may suspend the use of any Prospectus included in any registration contemplated by this Section by the Investors
if the Company believes in good faith that it would be seriously detrimental to the Company for resales to be made pursuant to a prospectus in the registration statement due to the existence of a material development or potential material
development, which is required to be disclosed in such prospectus and which disclosure at the time is not, in the good faith opinion of the Company, in the best interests of the Company (an Allowed Delay); provided, however, that so long
as the Registration Statement is on Form S-1 or on any other form that does not allow for incorporation by reference of reports and other materials filed by the Company pursuant .to Section 13(a) or 15(d) of the 1934 Act, the Company may suspend
sales under the Registration Statement (and such suspension shall be deemed to be an Allowed Delay without regard to the time periods mentioned above) (i) for the period commencing at the time that the Company disseminates a press release announcing
its preliminary financial results for any fiscal period and ending on the fifth Business Day after the earlier of (A) the date that the related report on Form 10-K or 10-Q, as applicable, Act is filed with the SEC and (B) the date on which such
report is required to be filed under the 1934 Act (without regard to Rule 12b-25 promulgated thereunder) and (ii) for the period commencing at the time that the Company disseminates a press release announcing a material development and ending on the
fifth Business Day after the earlier of (A) the date that the related report on Form 8-K is filed with the SEC and (B) the date on which such report is required to be filed under the 1934 Act (without regard to Rule 12b-25 promulgated thereunder) to
the extent, but in any such case only to the extent necessary to allow any post-effective amendment to the





---

Registration Statement or supplement to the Prospectus to be prepared and, if necessary, filed with the SEC and declared effective.



(iii) The Company shall promptly (a) notify the Investors in
writing of the existence of (but in no event, without the prior written consent of an Investor, shall the Company disclose to such Investor any of the facts or circumstances regarding) material non-public information giving rise to an Allowed Delay,
(b) advise the Investors in writing to cease all sales under the Registration Statement until the end of the Allowed Delay, and (c) use commercially reasonable efforts to terminate an Allowed Delay as promptly as practicable.



(d) Underwritten Offering. If any offering pursuant to a Registration Statement

Required Investors.



3. Company Obligations. The Company will use
commercially reasonable efforts to effect the registration of the Registrable Securities in accordance with the terms hereof, and pursuant thereto the Company will, as expeditiously as possible:

a Prospectus, including a preliminary prospectus, and all amendments and supplements thereto and such other documents as each Investor may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such Investor
that are covered by the related Registration Statement;



(d) in the
event the Company selects an underwriter for the offering, the Company shall enter into and perform its reasonable obligations under an underwriting agreement, in usual and customary form, including, without limitation, customary indemnification and
contribution obligations, with the underwriter of such offering;



(e) if
required by the underwriter, or if any Investor is described in the Registration Statement as an underwriter, the Company shall furnish, on the effective date of the Registration Statement (except with respect to clause (i) below) and on the date

(f) use commercially reasonable efforts to (i) prevent the issuance of any stop order or other suspension of effectiveness and, (ii) if
such order is issued, obtain the withdrawal of any such order at the earliest possible moment;



(g) prior to any public offering of Registrable Securities, use commercially reasonable efforts to register or qualify or cooperate with the Investors and their counsel in connection with the registration or
qualification of such Registrable Securities for offer and sale under the securities or blue sky laws of such jurisdictions requested by the Investors and do any and all other commercially reasonable acts or things necessary or advisable to enable
the distribution in such jurisdictions of the Registrable Securities covered by the Registration Statement; provided,





---

however, that the Company shall not be required in connection therewith or as a condition thereto to (i) qualify to do business in any jurisdiction
where it would not otherwise be required to qualify but for this Section 3(h), (ii) subject itself to general taxation in any jurisdiction where it would not otherwise be so subject but for this Section 3(h), or (iii) file a general consent to
service of process in any such jurisdiction;



(h) use commercially
reasonable efforts to cause all Registrable Securities covered by a Registration Statement to be listed on each securities exchange, interdealer quotation system or other market on which similar securities issued by the Company are then listed;



(i) immediately notify the Investors, at any time when a Prospectus
relating to Registrable Securities is required to be delivered under the 1933 Act, upon discovery that, or upon the happening of any event as a result of which, the Prospectus included in a Registration Statement, as then in effect, includes an
untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing, and at the request of any such holder,
promptly prepare and furnish to such holder 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 Registrable Securities, 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 in light of the circumstances then existing; and



(j) With a view to making available to the Investors the benefits of Rule 144
(or its successor rule) and any other rule or regulation of the SEC that may at any time permit the Investors to sell shares of Common Stock to the public without registration, from and after the Reporting Date the Company covenants and agrees to:
(i) make and keep public information available, as those terms are understood and defined in Rule 144, until the earlier of (A) six months after such date as all of the Registrable Securities may be resold pursuant to Rule 144(k) or any other rule
of similar effect or (B) such date as all of the Registrable Securities shall have been resold; (ii) file with the SEC in a timely manner all reports and other documents required of the Company under the 1934 Act; and (iii) furnish to each Investor
upon request, as long as such Investor owns any Registrable Securities, (A) a written statement by the Company that it has complied with the reporting requirements of the 1934 Act, (B) a copy of the Companys most recent Annual Report on Form
10-K or Quarterly Report on Form 10-Q, and (C) such other information as may be reasonably requested in order to avail such Investor of any rule or regulation of the SEC that permits the selling of any such Registrable Securities without
registration.



4. Due Diligence Review; Information. The Company
shall make available, during normal business hours, for inspection and review by the Investors, advisors to and representatives of the Investors (who may or may not be affiliated with the Investors and who are reasonably acceptable to the Company),
any underwriter participating in any disposition of shares of Common Stock on behalf of the Investors pursuant to a Registration Statement or amendments or supplements thereto or any blue sky, NASD or other filing, all financial and other records,
all SEC Filings (as defined in the Purchase Agreement) and other filings with the SEC, and all other corporate documents and properties of the Company as may be reasonably necessary for the purpose of such review, and cause the Companys
officers, directors and employees, within a reasonable time period, to supply all such information reasonably requested by the Investors or any such representative, advisor or underwriter in connection with such Registration Statement (including,
without limitation, in response to all questions and other inquiries reasonably made or submitted by any of them), prior to and from time to time after the filing and effectiveness of the Registration Statement for the sole purpose of enabling the
Investors and such representatives, advisors and underwriters and their respective accountants and attorneys to conduct initial and ongoing due diligence with respect to the Company and the accuracy of such Registration Statement.



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



5. Obligations of the Investors.



(a) Each Investor shall furnish in writing to the Company such information regarding
itself, the Registrable Securities held by it and the intended method of disposition of the Registrable Securities held by it, as





---

shall be reasonably required to effect the registration of such Registrable Securities and shall execute such documents in connection with such
registration as the Company may reasonably request. At least five (5) Business Days prior to the first anticipated filing date of any Registration Statement, the Company shall notify each Investor of the information the Company requires from such
Investor if such Investor elects to have any of the Registrable Securities included in the Registration Statement. An Investor shall provide such information to the Company at least two (2) Business Days prior to the first anticipated filing date of
such Registration Statement if such Investor elects to have any of the Registrable Securities included in the Registration Statement.



(b) Each Investor, by its acceptance of the Registrable Securities agrees to cooperate with the Company as reasonably requested by the Company in connection with the
preparation and filing of a Registration Statement hereunder, unless such Investor has notified the Company in writing of its election to exclude all of its Registrable Securities from such Registration Statement.



(c) In the event the Company, at the request of the Investors, determines to engage the
services of an underwriter, such Investor agrees to enter into and perform its obligations under an underwriting agreement, in usual and customary form, including, without limitation, customary indemnification and contribution obligations, with the
managing underwriter of such offering and take such other actions as are reasonably required in order to expedite or facilitate the dispositions of the Registrable Securities.



(d) Each Investor agrees that, upon receipt of any notice from the Company of either (i) the commencement of an Allowed Delay pursuant to
Section 2(c)(ii) or (ii) the happening of an event pursuant to Section 3(j) hereof, such Investor will immediately discontinue disposition of Registrable Securities pursuant to the Registration Statement covering such Registrable Securities, until
the Investors receipt of the copies of the supplemented or amended prospectus filed with the SEC and declared effective and, if so directed by the Company, the Investor shall deliver to the Company (at the expense of the Company) or destroy
(and deliver to the Company a certificate of destruction) all copies in the Investors possession of the Prospectus covering the Registrable Securities current at the time of receipt of such notice.



(e) No Investor may participate in any third party underwritten registration hereunder
unless it (i) agrees to sell the Registrable Securities on the basis provided in any underwriting arrangements in usual and customary form entered into by the Company, (ii) completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements, and (iii) agrees to pay its pro rata share of all underwriting discounts and commissions. Notwithstanding the foregoing, no Investor
shall be required to make any representations to such underwriter, other than those with respect to itself and the Registrable Securities owned by it, including its right to sell the Registrable Securities, and any indemnification in favor of the
underwriter by the Investors shall be several and not joint and limited in the case of any Investor, to the proceeds received by such Investor from the sale of its Registrable Securities. The scope of any such indemnification in favor of an
underwriter shall be limited to the same extent as the indemnity provided in Section 6(b) hereof.



6. Indemnification.



(a)
Indemnification by the Company. The Company will indemnify and hold harmless each Investor and its officers, directors, members, employees and agents, successors and assigns, and each other person, if any, who controls such Investor within
the meaning of the 1933 Act, against any losses, claims, damages or liabilities, joint or several, to which they may become subject under the 1933 Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon: (i) any untrue statement or alleged untrue statement of any material fact contained in any Registration Statement, any preliminary prospectus or final prospectus contained therein, or any amendment or
supplement thereof; (ii) any blue sky application or other document executed by the Company specifically for that purpose or based upon written information furnished by the Company filed in any state or other jurisdiction in order to qualify any or
all of the Registrable Securities under the securities laws thereof (any such application, document or information herein called aBlue Sky Application); (iii) 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; (iv) any violation by the Company or its agents of any rule or regulation promulgated under the 1933 Act applicable to the Company or its
agents and relating to action or inaction required of the Company in connection with such registration (except to the extent arising from a breach by such Investor of the terms hereof); or (v) any failure to register or qualify the Registrable
Securities included in any such Registration in any state where the Company or its agents has affirmatively undertaken or agreed in writing that the Company will undertake such registration or qualification on an Investors behalf (the
undertaking of any underwriter chosen by the Company being attributed to the Company) and will reimburse such Investor, and each such officer, director or member and each such controlling person for any legal or other expenses reasonably





---

incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that
the Company will 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 by such Investor or any such controlling person in writing specifically for use in such Registration Statement or Prospectus.



(b) Indemnification by the Investors. In connection with any registration pursuant to the terms of this Agreement, each Investor will furnish to the Company in
writing such information as the Company reasonably requests concerning the holders of Registrable Securities or the proposed manner of distribution for use in connection with any Registration Statement or Prospectus and agrees, severally but not
jointly, to indemnify and hold harmless, to the fullest extent permitted by law, the Company, its directors, officers, employees, stockholders and each person who controls the Company (within the meaning of the 1933 Act) against any losses, claims,
damages, liabilities and expense (including reasonable attorney fees) resulting from (i) any untrue statement of a material fact or any omission of a material fact required to be stated in the Registration Statement or Prospectus or preliminary
prospectus or amendment or supplement thereto or necessary to make the statements therein not misleading, to the extent, but only to the extent that such untrue statement or omission is contained in any information furnished in writing by such
Investor to the Company specifically for inclusion in such Registration Statement or Prospectus or amendment or supplement thereto or (ii) a breach by such Investor of the terms hereof. In no event shall the liability of an Investor be greater in
amount than the dollar amount of the proceeds (net of all expense paid by such Investor in connection with any claim relating to this Section 6 and the amount of any damages such holder has otherwise been required to pay by reason of such untrue
statement or omission) received by such Investor upon the sale of the Registrable Securities included in the Registration Statement giving rise to such indemnification obligation.



(c) Conduct of Indemnification Proceedings. Any person entitled to indemnification hereunder shall (i) give prompt notice to the
indemnifying party of any claim with respect to which it seeks indemnification and (ii) permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party; provided that any person
entitled to indemnification hereunder shall have the right to employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel shall be at the expense of such person unless (a) the indemnifying party
has agreed to pay such fees or expenses, or (b) the indemnifying party shall have failed to assume the defense of such claim and employ counsel reasonably satisfactory to such person or (c) in the reasonable judgment of any such person, based upon
written advice of its counsel, a conflict of interest exists between such person and the indemnifying party with respect to such claims (in which case, if the person notifies the indemnifying party in writing that such person elects to employ
separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of such claim on behalf of such person); 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 hereunder, except to the extent that such failure to give notice shall materially adversely affect the indemnifying party in the defense of any such claim
or litigation. It is understood that the indemnifying party shall not, in connection with any proceeding in the same jurisdiction, be liable for fees or expenses of more than one separate firm of attorneys at any time for all such indemnified
parties. No indemnifying party will, except with the consent of the 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 of such claim or litigation.



(d) Contribution. If for any reason the indemnification provided for in the preceding paragraphs (a) and (b) is unavailable to an indemnified party or insufficient to hold it harmless, other than as
expressly specified therein, then the indemnifying party shall contribute to the amount paid or payable by the indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault
of the indemnified party and the indemnifying party, as well as any other relevant equitable considerations. No person guilty of fraudulent misrepresentation within the meaning of Section 11(f) of the 1933 Act shall be entitled to contribution from
any person not guilty of such fraudulent misrepresentation. In no event shall the contribution obligation of a holder of Registrable Securities be greater in amount than the dollar amount of the proceeds (net of all expenses paid by such holder in
connection with any claim relating to this Section 6 and the amount of any damages such holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission) received by it upon the sale of
the Registrable Securities giving rise to such contribution obligation.
