REGISTRATION

Section 2.01.    Shelf Registration Statement. (a) As a condition to the closing of the transactions contemplated by the Purchase Agreement, the Company has filed with the SEC a Shelf Registration Statement (the “Registration Statement”) (which shall be an Automatic Shelf Registration Statement (as such term is defined in Rule 405 under the Securities Act) if the Company is then eligible to file such a registration statement) registering for resale all Registrable Securities under the Securities Act in accordance with the methods of distribution elected by the Holders and set forth in the Registration Statement, and, if applicable, shall use its commercially reasonable efforts to cause the Registration Statement to become effective under the Securities Act. The Company shall use its commercially reasonable efforts to keep the Registration Statement continuously effective under the Securities Act in order to permit the Prospectus forming a part thereof to be usable by the Holders until the date as of which there are no Registrable Securities outstanding. Without limiting the foregoing, the Company shall, to the extent not included in the Registration Statement, file on the Closing Date (as such term is defined in the Purchase Agreement) a Prospectus supplement naming each such Holder (subject to receipt of information reasonably requested by the Company necessary to complete

4

such Prospectus supplement). The Registration Statement when declared effective (including the documents incorporated therein by reference) will comply in all material respects as to form with all applicable requirements of the Securities Act and the Exchange Act and will not contain 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.

(b)    If the continued use of the Shelf Registration Statement at any time would require the Company to make an Adverse Disclosure, the Company may, upon written notice of such action to the Holders, suspend use of the Registration Statement (an “Unusual Shelf Suspension”). The Company shall not exercise its right hereunder to an Unusual Shelf Suspension on more than two occasions or in aggregate more than sixty days in any six-month period. In addition, the Company may, upon giving written notice to the Holders, suspend the use of the Registration Statement during regular quarterly periods beginning on the first day of the first calendar month of each quarter and ending on the day following the date that the Company releases earnings in respect of the previous calendar quarter (a “Regular Shelf Suspension,” together with an Unusual Shelf Suspension, a “Shelf Suspension”). In the case of a Shelf Suspension, the Holders shall suspend use of the applicable Prospectus in connection with any sale or purchase of, or offer to sell or purchase, any Registrable Securities, upon receipt of the notice referred to above. The Company shall immediately notify the Holders upon the termination of any Shelf Suspension, amend or supplement the Prospectus, if necessary, so it does not contain any untrue statement or omission and furnish to the Holders, such number of copies of the Prospectus as so amended or supplemented as the Holders may reasonably request. The Company shall, if necessary, supplement or make amendments to the Registration Statement, if required by the registration form used by the Company for the shelf registration or by the instructions applicable to such registration form or by the Securities Act. The Company and Holders agree that March 1, 2017, shall be considered an Unusual Shelf Suspension.

Section 2.02.    Obligations of the Company. (a) In connection with any Sale of Registrable Securities that will result in such securities no longer being Registrable Securities, the Company will cooperate with the applicable Holder to (i) rescind any Securities Act transfer restrictions or notations applicable to the Registrable Securities and, if the Registrable Securities are certificated, facilitate the timely preparation and delivery of certificates representing Registrable Securities to be Sold and not bearing any restrictive Securities Act legends and (ii) register such Registrable Securities in such denominations and such names as such Holder may request at least two Business Days prior to such Sale of Registrable Securities; provided that the Company may satisfy its obligations hereunder without issuing physical stock certificates through the use of the Depository Trust Company’s Direct Registration System. In addition, and so long as the applicable Holder is not an Affiliate of the Company in the opinion of counsel to the Company, the Company shall take or cause to be taken such actions as are reasonably necessary in order to cause any legend, notation or similar designation restricting transferability of the Registrable Securities held by such Holder to be removed and to rescind any transfer restrictions or notations applicable to the Registrable Securities effective as of the date that is six months following the Closing Date (as such term is

5

defined in the Purchase Agreement) upon receipt of an undertaking by such Holder that it will not consummate any Sales of such securities prior to the one-year anniversary of the Closing Date if it receives notification by the Company that it is not current in its periodic reports.

(b)    None of the Company, Buyer or any of their respective Affiliates shall have any obligation to facilitate or participate in any underwritten offering, prepare any Prospectus supplement (other than a Prospectus supplement to an existing shelf registration statement to name the Holders as selling shareholders), participate in any due diligence, execute any agreements or certificates or deliver legal opinions or obtain comfort letters in respect of the Registrable Securities or any Sale thereof.

(c)    With a view to making available to the Holders of Registrable Securities the benefits of Rule 144 promulgated under the Securities Act and other rules and regulations of the SEC that may at any time permit a Holder of Registrable Securities to sell securities of the Company to the public without registration, the Company will (i) use its commercially reasonable efforts to file in a timely manner all reports and other documents required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted thereunder and (ii) make and keep available information necessary to comply with Rule 144 at all times, all to the extent required from time to time to enable such Holder to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act, as such rule may be amended from time to time, or any other rules or regulations now existing or hereafter adopted by the SEC.

(d)    Should a Holder Transfer any Registrable Securities owned by it pursuant to (i) a bona-fide gift or (ii) a distribution for no consideration to a direct or indirect owner of such Holder then, upon request by such Holder, the Company shall promptly prepare and file with the SEC a Prospectus supplement, if necessary, to accommodate the sale of Registrable Securities under the Registration Statement by any recipient of Registrable Securities pursuant to clause (i) or (ii) above, and any such recipient shall, upon its agreement in writing to be bound as a Holder by the provisions of this Agreement, thereafter be deemed to be a “Holder” for all purposes of this Agreement.

Section 2.03.    Obligations of the Holders. (a) As a condition precedent to the inclusion of any Registrable Securities in any Shelf Registration, the Company may require each Holder to furnish such information regarding the distribution of such securities and such other information relating to such Holder, its ownership of Registrable Securities and other matters as the Company may from time to time reasonably request in writing. Each such Holder agrees to furnish such information and to cooperate as reasonably necessary to enable the Company to comply with the provisions of this Agreement. If a Holder fails to promptly provide the requested information after prior written notice of such request and the requested information is required by applicable law to be included in the Registration Statement, the Company shall be entitled to refuse to include for registration such Holder’s Registrable Securities in the Registration Statement.

6

(b)    Each Holder shall, as promptly as reasonably practicable, notify the Company, at any time when a Prospectus is required to be delivered (or deemed delivered) under the Securities Act, of the occurrence of an event, of which such Holder has knowledge, relating to such Holder or its Sale of Registrable Securities thereunder requiring the preparation of a supplement or amendment to such Prospectus so that, as thereafter delivered (or deemed delivered) to the purchasers of such Registrable Securities, such Prospectus will 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 statements therein, in light of the circumstances under which they are made, not misleading.

(c)    Each Holder agrees by acquisition of such Registrable Securities, that, upon receipt of any written notice from the Company of the occurrence of an Unusual Shelf Suspension, such Holder will (i)(A) shall treat the notice as confidential information, (B) shall not use any confidential information for any purpose, (C) shall not trade while aware of such confidential information unless and until such information shall become public or shall cease to be material and (D) shall not disclose any such information to any Person; provided, that any such Holder may disclose confidential information if such disclosure is required by legal process, but such Holder shall cooperate with the Company to limit the extent of such disclosure through protective order or otherwise, and to seek confidential treatment of the information and (ii) will cease any Transfers of Registrable Securities until such suspension has been lifted.

(d)    Each Holder agrees that it will not use any free writing prospectus (as defined in Rule 405 under the Securities Act) in connection with any Transfer of Registrable Securities other than one that has been provided by the Company for use in connection therewith.

Section 2.04.    Indemnification. (a) The Company shall indemnify and hold harmless each Holder that is a seller of Registrable Securities, and the employees, officers, directors, partners, managers and members of each such Holder, and each Person, if any, who controls such Holder within the meaning of the Securities Act or the Exchange Act, from and against any Damages; provided, however, that the Company shall not be liable for any Damages to the extent that they arise out of or are based upon actions or omissions made in reliance upon and in conformity with written information furnished by or on behalf of any such Holder, controlling Person or other aforementioned Person expressly for use in connection with such registration.

(b)    In connection with any Registration Statement in which a Holder that is a seller of Registrable Securities is participating, each such Holder shall, severally and not jointly, indemnify and hold harmless the Company, and each of its directors, officers and employees, each Person (if any) who controls the Company within the meaning of the Securities Act, any other Holder selling securities in such registration statement and any controlling Person of any such other Holder, from and against any Damages, in each case only to the extent that such Damages arise out of or are based upon actions or omissions made in reliance upon and in conformity with written information furnished by or on behalf of such selling Holder expressly for use in connection with the Registration Statement; provided, however, that in no event shall the aggregate amounts payable by

7

any Holder by way of indemnity or contribution under Section 2.04(b) and Section 2.04(d) exceed the proceeds from the offering received by such Holder (net of any Selling Expenses paid by such Holder), except in the case of fraud or willful misconduct by such Holder.

(c)    Promptly after receipt by an indemnified party under this Section 2.04 of notice of the commencement of any action (including any governmental action) for which a party may be entitled to indemnification hereunder, such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 2.04, give the indemnifying party prompt notice of the commencement thereof. The indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In the event that the indemnified party does not request appointment of counsel from the indemnifying party, the indemnifying party shall have the right to participate in such action and, to the extent the indemnifying party so desires, participate jointly with any other indemnifying party to which notice has been given, and to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party (together with all other indemnified parties that may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the fees and expenses to be paid by the indemnifying party, if (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such action. It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm (in addition to local counsel) for all such indemnified parties, and that all such fees shall be reimbursed as they are incurred. Such firm shall be designated in writing by the applicable Holder in the case of parties indemnified pursuant to Section 2.04(a) and by the Company in the case of parties indemnified pursuant to Section 2.04(b). The failure to give notice to the indemnifying party within a reasonable time of the commencement of any such action shall relieve such indemnifying party of any liability to the indemnified party under this Section 2.04, to the extent that such failure materially prejudices the indemnifying party’s ability to defend such action. The failure to give notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party other than pursuant to this Section 2.04. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment.

(d)    To provide for just and equitable contribution to joint liability under the Securities Act in any case in which either (i) any party otherwise entitled to indemnification hereunder makes a claim for indemnification pursuant to this Section 2.04

8

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 2.04 provides for indemnification in such case, or (ii) contribution under the Securities Act may be required on the part of any party hereto for which indemnification is provided under this Section 2.04, then, and in each such case, such parties will contribute to the aggregate losses, claims, damages, liabilities or expenses to which they may be subject (after contribution from others) in such proportion as is appropriate to reflect the relative fault of each of the indemnifying party and the indemnified party in connection with the statements, omissions or other actions that resulted in such loss, claim, damage, liability or expense, as well as to reflect any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or allegedly untrue statement of a material fact, or the omission or alleged omission of 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; provided, however, that, in any such case (x) no Holder will be required to contribute any amount in excess of the public offering price of all such Registrable Securities offered and sold by such Holder pursuant to such Registration Statement and (y) no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation; and provided further that in no event shall a Holder’s liability pursuant to this Section 2.04(d), when combined with the amounts paid or payable by such Holder pursuant to Section 2.04(b), exceed the proceeds from the offering received by such Holder (net of any Selling Expenses paid by such Holder), except in the case of willful misconduct or fraud by such Holder. The Company and Holders agree that it would not be just and equitable if contribution pursuant to this Article 2 were determined by pro rata allocation or by any other method of allocation which does not take account of the considerations referred to in this Section 2.04(d).

(e)    The obligations of the Company and Holders under this Section 2.04 shall survive the Transfer of securities.

Section 2.05.    Registration Expenses. All Registration Expenses shall be borne by the Company. All Selling Expenses shall be borne by the Holders pro-rata on the basis of the number of Registrable Securities sold, or as otherwise agreed by the Holders.

ARTICLE 3
