	Section 2.	Demand Registrations. 

 (a) Right to Request Registration. From and after the date hereof, any Holder or Holders (“Initiating Holders”) may request registration under the Securities Act of all or part of
the Registrable Common Stock (“Demand Registration”) at any time and from time to time; provided further, that the Company shall not file any registration statement pursuant to any Demand Registration until 365 days after the date
of the Purchase Agreement. 
 Within ten (10) Business Days after receipt of any such request for Demand Registration, the
Company shall give written notice of such request to all other Holders of Registrable Common Stock, if any, and shall, subject to the provisions of Section 2(c) hereof, include in such registration all such Registrable Common Stock with respect
to which the Company has received written requests for inclusion therein within twenty (20) Business Days after the receipt of the Company’s notice. 
 (b) Priority on Demand Registrations. If the managing underwriters of a requested Demand Registration advise the Company in writing that in their opinion the shares of Registrable Common Stock
proposed to be included in any such registration exceeds the number of securities that can be sold in such offering and/or that the number of shares of Registrable Common Stock proposed to be included in any such registration would materially
adversely affect the price per share of the Company’s equity securities to be sold in such offering, the Company shall include in such registration only the number of shares of Registrable Common Stock that, in the opinion of such managing
underwriters, can be sold. If the number of shares that can be sold is less than the number of shares of Registrable Common Stock proposed to be registered, the Company shall allocate the amount of Registrable Common Stock to be so sold among the
Holders pro rata on the basis of Registrable Common Stock requested to be included in such registration by each Holder electing to participate in such registration. If the number of shares that can be sold, as determined by the managing
underwriters, exceeds the number of shares of Registrable Common Stock proposed to be sold, such excess shall be allocated pro rata among the other holders of Common Stock, if any, desiring to participate in such registration based on the amount of
such Common Stock initially requested to be registered by such Holders or as such Holders may otherwise agree. 
 (c)
Restrictions on Demand Registrations. The Company shall not be obligated to effect any Demand Registration within six (6) months after the effective date of a previous Demand Registration or a previous registration under which the
Initiating Holders had piggyback rights pursuant to Section 3 hereof wherein the Initiating Holders were permitted to register, and sold, at least 50% of the shares of Registrable Common Stock requested to be included therein. The Company may
(i) postpone for up to ninety (90) days the filing or the effectiveness of a Registration Statement for a Demand Registration if, based on the good faith judgment of the Company’s board of directors, such postponement or withdrawal is
necessary in order to avoid 







 
premature disclosure of a matter the board has determined would not be in the best interest of the Company to be disclosed at such time or (ii) postpone the filing of a Demand Registration
in the event the Company shall be required to prepare audited financial statements as of a date other than its fiscal year and (unless the Holders requesting such registration agree to pay the expenses of such an audit); provided, however, that in
no event shall the Company withdraw a Registration Statement under clause (i) after such Registration Statement has been declared effective; and provided, further, however, that in any of the events described in clause (i) or
(ii) above, the Initiating Holders requesting such Demand Registration shall be entitled to withdraw such request. The Company shall provide written notice to the Initiating Holders requesting such Demand Registration of (x) any
postponement or withdrawal of the filing or effectiveness of a Registration Statement pursuant to this Section 2(c), (y) the Company’s decision to file or seek effectiveness of such Registration Statement following such withdrawal or
postponement and (z) the effectiveness of such Registration Statement. 
 (d) Selection of Underwriters. If any of
the Registrable Common Stock covered by a Demand Registration hereof is to be sold in an underwritten offering, American Capital shall have the right to select the managing underwriter(s) to administer the offering subject to the approval of the
Company, which approval shall not be unreasonably withheld. 
 (e) Effective Period of Demand Registrations. After any
Demand Registration filed pursuant to this Agreement has become effective, the Company shall use its best efforts to keep such Demand Registration effective for a period equal to 180 days from the date on which the SEC declares such Demand
Registration effective (or if such Demand Registration is not effective during any period within such 180 days, such 180-day period shall be extended by the number of days during such period when such Demand Registration is not effective), or such
shorter period that shall terminate when all of the Registrable Common Stock covered by such Demand Registration has been sold pursuant to such Demand Registration. If the Company shall withdraw or reduce the number of shares of Registrable Common
Stock that is subject to any Demand Registration pursuant to subsection (b) of this Section 2 (a “Withdrawn Demand Registration”), the Initiating Holders of the Registrable Common Stock remaining unsold and originally
covered by such Withdrawn Demand Registration shall be entitled to a replacement Demand Registration that (subject to the provisions of this Section 2) the Company shall use its best efforts to keep effective for a period commencing on the
effective date of such Demand Registration and ending on the earlier to occur of the date (i) that is 180 days from the effective date of such Demand Registration and (ii) on which all of the Registrable Common Stock covered by such Demand
Registration has been sold. Such additional Demand Registration otherwise shall be subject to all of the provisions of this Agreement. 
 (f) Underwritten Offerings. Notwithstanding the foregoing, in no event shall the Company be obligated to effect more than one (1) underwritten offering hereunder in any single six
(6) month period, with the first such period measured from the date of the first Demand Registration and ending on the same date during the six (6) months following such Demand Registration, whether or not a Business Day. 








	Section 3.	Piggyback Registrations. 

 (a) Right to Piggyback. Beginning 180 days after the date of the Purchase Agreement and until the termination of the Management Agreement, whenever the Company proposes to register any of its
common equity securities under the Securities Act (other than a registration statement on Form S-8 or on Form S-4 or any similar successor forms thereto), whether for its own account or for the account of one or more stockholders of the Company, and
the registration form to be used may be used for any registration of Registrable Common Stock (a “Piggyback Registration”), the Company shall give prompt written notice (in any event within ten (10) business days after its
receipt of notice of any exercise of other demand registration rights) to all Holders of its intention to effect such a registration and, subject to Sections 3(b) and 3(c), shall include in such registration all Registrable Common Stock with respect
to which the Company has received written requests for inclusion therein within twenty (20) days after the receipt of the Company’s notice. The Company may postpone or withdraw the filing or the effectiveness of a Piggyback Registration at
any time in its sole discretion. 
 (b) Priority on Primary Registrations. If a Piggyback Registration is an underwritten
primary registration on behalf of the Company, and the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included in such registration exceeds the number that can be sold in such
offering and/or that the number of shares of Registrable Common Stock proposed to be included in any such registration would adversely affect the price per share of the Company’s equity securities to be sold in such offering, the underwriting
shall be allocated among the Company and all Holders pro rata on the basis of the Common Stock and Registrable Common Stock offered for such registration by the Company and each Holder, respectively, electing to participate in such registration.

 (c) Priority on Secondary Registrations. If a Piggyback Registration is an underwritten secondary registration on
behalf of a holder of the Company’s securities other than Registrable Common Stock (“Non-Holder Securities”), and the managing underwriters advise the Company in writing that in their opinion the number of securities requested
to be included in such registration exceeds the number that can be sold in such offering and/or that the number of shares of Registrable Common Stock proposed to be included in any such registration would adversely affect the price per share of the
Company’s equity securities to be sold in such offering, the underwriting shall be allocated among the holders of Non-Holder Securities and all Holders pro-rata on the basis of the Non-Holder Securities and Registrable Common Stock offered for
such registration by the holder of Non-Holder Securities and each Holder, respectively, electing to participate in such registration. 
 (d) Selection of Underwriters. If any Piggyback Registration is an underwritten primary offering, the Company shall have the right to select the managing underwriter or underwriters to administer
any such offering. 
 (e) Other Registrations. If the Company has previously filed a Registration Statement with respect
to Registrable Common Stock pursuant to Section 2 hereof or pursuant to this Section 3, and if such previous registration has not been withdrawn or abandoned, the Company shall not be obligated to cause to become effective any other
registration of any of its securities under the Securities Act, whether on its own behalf or at the request of any holder or holders of such securities, until a period of at least three (3) months has elapsed from the effective date of such
previous registration. 








	Section 4.	Holdback Agreement. 


In connection with an underwritten primary or secondary offering to the public, each Holder agrees, subject to any exceptions that may be
agreed upon at the time of such offering, not to sell or otherwise transfer or dispose of any shares of Registrable Common Stock (or other securities) of the Company held by them (other than Registrable Common Stock included in such offering in
accordance with the terms hereof) for a period equal to the lesser of one hundred eighty (180) days following the effective date of a Registration Statement of the Company filed under the Securities Act or such shorter period as the managing
underwriter shall agree to; provided that all other stockholders who own more than ten percent (10%) of the outstanding Common Stock of the Company and all officers and directors of the Company enter into similar agreements. Such agreement
shall be in writing in form reasonably satisfactory to the Company and the managing underwriter. The Company may impose stop-transfer instructions with respect to the shares of Registrable Common Stock (or other securities) subject to the foregoing
restriction until the end of said period. 
  

	Section 5.	Registration Procedures. 

 Whenever the Holders request that any Registrable Common Stock be registered pursuant to this Agreement, the Company shall use its commercially reasonable efforts to effect and maintain the registration
and the sale of such Registrable Common Stock in accordance with the intended methods of disposition thereof, and pursuant thereto the Company shall as expeditiously as possible: 

(a) prepare and file with the SEC a Registration Statement with respect to such Registrable Common Stock and use its best efforts to
cause such Registration Statement to become effective as soon as practicable thereafter; and before filing a Registration Statement or Prospectus or any amendments or supplements thereto, furnish to the Holders of Registrable Common Stock covered by
such Registration Statement and the underwriter or underwriters, if any, copies of all such documents proposed to be filed, including, if requested by such Holders, documents incorporated by reference in the Prospectus and, if requested by such
Holders, the exhibits incorporated or deemed incorporated by reference, and such Holders shall have the opportunity to object to any information pertaining to such Holders that is contained therein and the Company will make the corrections
reasonably requested by such Holders 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 SEC such amendments and supplements to such Registration Statement and the Prospectus used in connection
therewith as may be necessary to keep such Registration Statement effective, in the case of Demand Registration, for a period not less than 180 days, or such shorter period as is necessary to complete the distribution of the securities covered by
such Registration Statement and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such Registration Statement during such period in accordance with the intended methods of disposition by
the sellers thereof set forth in such Registration Statement; 







 (c) furnish to each seller of Registrable Common Stock (without charge) such number of
copies of such Registration Statement, each amendment and supplement thereto, the Prospectus included in such Registration Statement (including each preliminary Prospectus) and such other documents as such seller may reasonably request in order to
facilitate the disposition of the Registrable Common Stock owned by such seller, and the Company consents to the use of such Prospectus, including each preliminary Prospectus, by Holders of Registrable Common Stock, in connection with the offering
and sale of Registrable Common Stock covered by any such Prospectus; 
 (d) use its commercially reasonable efforts to register
or qualify such Registrable Common Stock under such other securities or blue sky laws of such jurisdictions as any seller reasonably requests and do any and all other acts and things which may be reasonably necessary or advisable to enable such
seller to consummate the disposition in such jurisdictions of the Registrable Common Stock owned by such seller (provided, that the Company will not be required to (i) qualify generally to do business in any jurisdiction where it would not
otherwise be required to qualify but for this subparagraph (d), (ii) subject itself to taxation in any such jurisdiction or (iii) consent to general service of process in any such jurisdiction); 

(e) notify each seller of such Registrable Common Stock, at any time when a Prospectus relating thereto is required to be delivered under
the Securities Act, of the occurrence of any event as a result of which the Registration Statement, including the Prospectus contained therein, contains an untrue statement of a material fact or omits any fact required to be stated therein or
necessary to make the statements therein not misleading, and, at the request of any such seller, the Company shall prepare a supplement or amendment to such Registration Statement so that, as thereafter delivered to the purchasers of such
Registrable Common Stock, such Prospectus shall not contain an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein not misleading; 

(f) in the case of an underwritten offering, enter into such customary agreements (including underwriting agreements in customary form)
and take all such other actions as the Holders of a majority of number of shares of the Registrable Common Stock being sold or the underwriters, if any, reasonably request in order to expedite or facilitate the disposition of such Registrable Common
Stock (including making executive officers of the Company available to participate in, and cause them to cooperate with the underwriters in connection with, “road-show” and other customary marketing activities (including one-on-one
meetings with prospective purchasers of the Registrable Common Stock), and cause to be delivered to the underwriters and the sellers, if any, opinions of counsel to the Company in customary form, covering such matters as are customarily covered by
opinions for an underwritten public offering as the underwriters may request and addressed to the underwriters and the sellers; 

(g) subject to receipt of reasonably acceptable confidentiality agreements, make available, for inspection by representative of a seller
of Registrable Common Stock, any underwriter participating in any disposition pursuant to such Registration Statement, and any attorney, accountant or other agent retained by any such seller or underwriter, all financial and








 
other records, pertinent corporate documents and properties of the Company, and cause the Company’s officers, directors and independent accountants to supply all information reasonably
requested by any such seller, underwriter, attorney, accountant or agent in connection with such Registration Statement; 
 (h)
to use its commercially reasonable efforts to cause all such Registrable Common Stock to be listed on each securities exchange on which securities of the same class issued by the Company are then listed or, if no such similar securities are then
listed, on a national securities exchange selected by the Company; 
 (i) provide a transfer agent and registrar for all such
Registrable Common Stock not later than the effective date of such Registration Statement; 
 (j) if requested, cause to be
delivered, immediately prior to the effectiveness of the Registration Statement (and, in the case of an underwritten offering, at the time of delivery of any Registrable Common Stock sold pursuant thereto), letters from the Company’s
independent certified public accountants addressed to each selling Holder (unless such selling Holder does not provide to such accountants the appropriate representation letter required by rules governing the accounting profession) and each
underwriter, if any, stating that such accountants are independent public accountants within the meaning of the Securities Act and the applicable rules and regulations adopted by the SEC thereunder, and otherwise in customary form and covering such
financial and accounting matters as are customarily covered by letters of the independent certified public accountants delivered in connection with primary or secondary underwritten public offerings, as the case may be; 

(k) make generally available to its stockholders a consolidated earnings statement (which need not be audited) for the 12 months (or, if
applicable, such shorter period that the Company has been in existence) beginning after the effective date of a Registration Statement as soon as reasonably practicable after the end of such period, which earnings statement shall satisfy the
requirements of an earning statement under Section 11(a) of the Securities Act and Rule 158 thereunder; 
 (l) cooperate
with each selling Holder of Registrable Common Stock and each underwriter participating in the disposition of such Registrable Common Stock and their respective counsel in connection with any filings required to be made with the Financial Industry

marketing process) in the marketing of Registrable Common Stock in any underwritten offering; 
 (m) use its best efforts to
prevent the issuance of any stop order or other suspension of effectiveness of a Registration Statement, or the suspension of the qualification of any of the Registrable Common Stock for sale in any jurisdiction and, if such an order or suspension
is issued, to use reasonable efforts to obtain the withdrawal of such order or suspension at the earliest possible moment and to notify each seller of Registrable Common Stock being sold of the issuance of such order and the resolution thereof or
its receipt of actual notice of the initiation or threat of any proceeding for such purpose; 







 (n) promptly notify each seller of Registrable Common Stock and the underwriter or
underwriters, if any:

(ii) of any written request by the SEC for amendments or supplements to the Registration Statement or Prospectus; 

(iii) of the notification to the Company by the SEC of its initiation of any proceeding with respect to the issuance by the SEC of any
stop order suspending the effectiveness of the Registration Statement; and 
 (iv) of the receipt by the Company of any
notification with respect to the suspension of the qualification of any Registrable Common Stock for sale under the applicable securities or blue sky laws of any jurisdiction. 
 (o) At all times after the Company has filed a registration statement with the SEC pursuant to the requirements of either the Securities Act or the Exchange Act, the Company shall file 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 by the SEC thereunder, and take such further action as any Holders may reasonably request, all to the extent required to
enable such Holders to be eligible to sell Registrable Common Stock pursuant to Rule 144 under the Securities Act (or any similar rule then in effect). 
 (p) As a condition to being included in any Registration Statement, the Company may require each seller of Registrable Common Stock as to which any registration is being effected to furnish to the Company
any other information regarding such seller and the distribution of such securities as the Company may from time to time reasonably request in writing. 
 (q) Each seller of Registrable Common Stock agrees by having its stock treated as Registrable Common Stock hereunder that, upon notice of the happening of any event as a result of which the Prospectus
included in such Registration Statement contains an untrue statement of a material fact or omits any material fact necessary to make the statements therein not misleading (a “Suspension Notice”), such seller will forthwith
discontinue disposition of Registrable Common Stock until such seller is advised in writing by the Company that the use of the Prospectus may be resumed and is furnished with a supplemented or amended Prospectus as contemplated by Section 5(e)
hereof, and, if so directed by the Company, such seller, at its option, either will destroy or deliver to the Company (at the Company’s expense) all copies, other than permanent file copies then in such seller’s possession, of the
Prospectus covering such Registrable Common Stock current at the time of receipt of such notice; provided, however, that such postponement of sales of Registrable Common Stock by the Holders shall not exceed thirty (30) days in the aggregate in
any three-month period or ninety (90) days in the aggregate in any one year except as a result of a refusal by the SEC to declare any post-effective amendment to the Registration Statement effective after the Company has used all commercially
reasonable 







 
efforts to cause such post-effective amendment to be declared effective, in which case the Company shall terminate the suspension of the use of the Registration Statement immediately following
the effective date of the post-effective amendment. If the Company shall give any notice to suspend the disposition of Registrable Common Stock pursuant to a Prospectus, the Company shall extend the period of time during which the Company is
required to maintain the Registration Statement effective pursuant to this Agreement by the number of days during the period from and including the date of the giving of such notice to and including the date such seller either is advised by the
Company that the use of the Prospectus may be resumed or receives the copies of the supplemented or amended Prospectus contemplated by Section 5(e). In any event, the Company shall not be entitled to deliver more than three (3) Suspension
Notices in any one year. 
  

	Section 6.	Registration Expenses. 

 (a) All fees and expenses incident to the Company’s performance of or compliance with this Agreement, including, without limitation, all registration and filing fees, fees and expenses of compliance
with securities or blue sky laws, listing application fees, printing, word processing, telephone, messenger and delivery expenses, transfer agent’s and registrar’s fees, cost of distributing Prospectuses in preliminary and final form as
well as any supplements thereto, and fees and disbursements of counsel for the Company, one counsel retained by the Holders of Registrable Common Stock (in accordance with Section 6(b)) and all independent certified public accountants and other
Persons retained by the Company (all such expenses being herein called “Registration Expenses”) (but not including any underwriting discounts or commissions attributable to the sale of Registrable Common Stock or fees and expenses
of more than one counsel representing the Holders of Registrable Common Stock, which shall be borne by the Holders), shall be borne by the Company (whether or not any Registration Statement is declared effective or any of the transactions described
herein is consummated). In addition, the Company shall pay its internal expenses, the expense of any annual audit or quarterly review, the expense of any liability insurance and the expenses and fees for listing the securities to be registered on
each securities exchange on which they are to be listed. 
 (b) In connection with each registration initiated hereunder
(whether a Demand Registration or a Piggyback Registration), the Company shall reimburse the Holders covered by such registration or sale for the reasonable fees and disbursements of one law firm chosen by the Holders of a majority of the number of
shares of Registrable Common Stock included in such registration sale. 
 (c) The obligation of the Company to bear the expenses
described in Section 6(a) and to reimburse the Holders for the expenses described in Section 6(b) shall apply irrespective of whether a registration, once properly demanded, if applicable, becomes effective, is withdrawn or suspended, is
converted to another form of registration and irrespective of when any of the foregoing shall occur; provided, however, that Registration Expenses for any Registration Statement withdrawn solely at the request of a Holder of Registrable Common Stock
(unless withdrawn following postponement of filing by the Company in accordance with Section 2(c) or any supplements or amendments to a Registration Statement or Prospectus resulting from a misstatement furnished to the Company by a Holder
shall be borne by such Holder. 








	Section 7.	Indemnification. 


(a) The Company shall indemnify and hold harmless, to the fullest extent permitted by law, each Holder, its officers, directors and
Affiliates, employees and agents of such Holder and each Person, if any, who controls such Holder (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) from and against all losses, claims, damages,
liabilities, judgments and expenses (including without limitation, the reasonable fees and other expenses incurred in connection with any suit, action, investigation or proceeding or any claim asserted) caused by, arising out of, in connection with
or based upon, any untrue or alleged untrue statement of material fact contained in any Registration Statement, Prospectus (including any preliminary Prospectus) or any amendment thereof or supplement thereto or any omission or alleged omission of a
material fact required to be stated therein or necessary to make the statements therein, in the case of the Prospectus in the light of the circumstances under which they were made, not misleading or any violation or alleged violation by the Company
of the Securities Act, the Exchange Act or applicable “blue sky” laws, except insofar as the same are made in reliance and in conformity with information relating to such Holder furnished in writing to the Company by such Holder expressly
for use therein or caused by such Holder’s failure to deliver to such Holder’s immediate purchaser a copy of the Prospectus or any amendments or supplements thereto (if the same was required by applicable law to be so delivered) after the
Company has furnished such Holder with a sufficient number of copies of the same. 
 (b) In connection with any Registration
Statement in which a Holder of Registrable Common Stock is participating, each such Holder shall furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration
Statement or Prospectus and, shall indemnify, to the fullest extent permitted by law, the Company, its officers, directors, Affiliates, and each Person who “controls” the Company within the meaning of the Securities Act (excluding American
Capital to the extent that American Capital is the Holder of the Registrable Common Stock), against all losses, claims, damages, liabilities and expenses arising out of or based upon any untrue or alleged untrue statement of material fact contained
in the Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein, in
the case of the Prospectus in the light of the circumstances under which they were made, not misleading, but only to the extent that the same are made in reliance and in conformity with information relating to such Holder furnished in writing to the
Company by such Holder expressly for use therein or caused by such Holder’s failure to deliver to such Holder’s immediate purchaser a copy of the Prospectus or any amendments or supplements thereto (if the same was required by applicable
law to be so delivered) after the Company has furnished such Holder with a sufficient number of copies of the same; provided, however, that the obligation to indemnify shall be several, not joint and several, among such Holders and the liability of
each such Holder shall be in proportion to and limited to the net amount received by such Holder from the sale of Registrable Common Stock pursuant to such Registration Statement. 

(c) Any Person entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying party of any claim
with respect to which it seeks indemnification and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, such indemnifying








 
party shall assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any
liability for any settlement made by the indemnified party without its consent (but such consent will not be unreasonably withheld, conditioned or delayed). An indemnifying party who is not entitled to, or elects not to, assume the defense of a
claim shall not be obligated to pay the fees and expenses of more than one counsel for each party indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party there may be one or more
legal or equitable defenses available to such indemnified party which are in addition to or may conflict with those available to another indemnified party with respect to such claim. Failure to give prompt written notice shall not release the
indemnifying party from its obligations hereunder. No indemnifying party shall, without the prior written consent of the indemnified party, consent to entry of any judgment or enter into any settlement or other compromise (i) which 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 or (ii) which includes any statement of admission of fault,
culpability or failure to act by or on behalf of such indemnified party. 
 (d) 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 or
the termination of this Agreement. 
 (e) If the indemnification provided for in or pursuant to this Section 7 is
unavailable, unenforceable or insufficient to hold harmless any indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to herein, then each applicable indemnifying party, in lieu of indemnifying such
indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or expenses 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 which result in such losses, claims, damages, liabilities or expenses as well as any other relevant equitable considerations. The relative
fault of the indemnifying party on the one hand and of the indemnified party on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission
to state a material fact relates to information supplied by the indemnifying party or by the indemnified party, and by such party’s relative intent, knowledge, access to information and opportunity to correct or prevent such statement or
omission. In no event shall the liability of any selling Holder be greater in amount than the amount of net proceeds received by such Holder upon such sale or the amount for which such indemnifying party would have been obligated to pay by way of
indemnification if the indemnification provided for under Section 7(a) or 7(b) hereof had been available under the circumstances. The indemnity and contribution agreements contained in this Section 7 are in addition to any liability which
the indemnifying Persons may otherwise have to the indemnified parties hereunder, under applicable law or at equity. 








	Section 8.	Participation in Underwritten Registrations. 

 No Person may participate in any registration hereunder that is underwritten unless such Person (a) agrees to sell such Person’s securities on the basis provided in any underwriting arrangements
approved by the Person or Persons entitled hereunder to approve such arrangements and (b) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements, opinions and other documents required under the terms
of such underwriting arrangements. 
  

	Section 9.	Rule 144. 

 The
Company covenants that it will file the reports required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted by the SEC thereunder in accordance with the requirements of the Securities Act and the
Exchange Act, and it will take such further action as any Holder may reasonably request to make available adequate current public information with respect to the Company meeting the current public information requirements of Rule 144(c) under the
Securities Act (to the extent such information is available), to the extent required to enable such Holder to sell Registrable Common Stock without registration under the Securities Act within the limitation of the exemptions provided by
(i) Rule 144 under the Securities Act, as such Rule may be amended from time to time, or (ii) any similar rule or regulation hereafter adopted by the SEC. Upon the request of any Holder, the Company will deliver to such Holder a written
statement as to whether it has complied with such information and requirements.
