 2. Registration under the Securities Act.

 (a) Except as set forth in Section 2(b) below, the Issuer and the Guarantors agree to use their
respective commercially reasonable efforts to file under the Securities Act a registration statement relating to an offer to exchange (such registration statement, the “Exchange Offer Registration Statement”,
and such offer, the “Exchange Offer”) any and all of the Securities for a like aggregate principal amount of debt securities issued by the Issuer and guaranteed by the Guarantors, which debt securities and
guarantees are substantially identical to the Securities and the related Guarantees, respectively (and are entitled to the benefits of the Indenture), except that they have been registered pursuant to an effective registration statement under the
Securities Act and do not contain provisions for Special Interest contemplated in Section 2(c) below (such new debt securities hereinafter called “Exchange Securities”). The Issuer and the Guarantors agree
to use their respective commercially reasonable efforts to (i) cause the Exchange Offer Registration Statement to be declared effective or to become effective under the Securities Act and (ii) complete the Exchange Offer no later than 365
days after the Closing Date. The Exchange Offer shall be registered under the Securities Act on the appropriate form and shall comply with all applicable tender offer rules and regulations under the Exchange Act. Unless the Exchange Offer would not
be permitted by applicable law or Commission policy, the Issuer further agrees to use its commercially reasonable efforts to (i) commence the Exchange Offer promptly following the Effective Time of such Exchange Offer Registration Statement,
(ii) hold the Exchange Offer open for at least 20 Business Days in accordance with Regulation 14E promulgated by the Commission under the Exchange Act, or longer if required by the federal securities laws and (iii) issue on or prior to 30
Business Days, or longer if required by the federal securities laws, after the date on which the Exchange Offer Registration Statement was declared effective by the Commission, Exchange Securities in exchange for the Registrable Securities tendered
prior thereto in the Exchange Offer. The Exchange Offer will be deemed to have been “completed” only (i) if the debt securities and related guarantees received by holders other than Restricted Holders in the Exchange Offer for
Registrable Securities are, upon receipt, transferable by each such holder without restriction under the Securities Act and the Exchange Act and without material restrictions under the blue sky or securities laws of a substantial majority of the
States of the United States of America and (ii) upon the Issuer having exchanged, pursuant to the Exchange Offer, Exchange Securities for all Registrable Securities that have been properly tendered and not withdrawn before the expiration of the
Exchange Offer, which shall be on a date that is at least 20 Business Days following the commencement of the Exchange Offer. The Issuer agrees (x) to include in the Exchange Offer Registration Statement a prospectus for use in any resales by
any holder of Exchange Securities that is a broker-dealer and (y) to keep such Exchange Offer Registration Statement effective for a period (the “Resale 

  
 - 6 -

 
Period”) beginning when Exchange Securities are first issued in the Exchange Offer and ending upon the earlier of the expiration of the 120th day after the Exchange Offer has been completed or such time as such
broker-dealers no longer own any Registrable Securities. With respect to such Exchange Offer Registration Statement, such holders shall have the benefit of the rights of indemnification and contribution set forth in Subsections 6(a), (c),
(d) and (e). 
 (b) If (i) on or prior to the time the Exchange Offer is completed, the Exchange Offer
is not permitted by applicable law or Commission policy or existing law or Commission interpretations are changed such that the debt securities or the related guarantees received by holders other than Restricted Holders in the Exchange Offer for
Registrable Securities are not or would not be, upon receipt, transferable by each such holder without restriction under the Securities Act, (ii) the Exchange Offer has not been completed within 365 days following the Closing Date or
(iii) any holder of Registrable Securities notifies the Issuer prior to the 20th Business Day following the completion of the Exchange Offer that: (A) it is prohibited by law or Commission policy from participating in the Exchange Offer,
(B) it may not resell the Exchange Securities to the public without delivering a prospectus and the prospectus supplement contained in the Exchange Offer Registration Statement is not appropriate or available for such resales or (C) it is
a broker-dealer and owns Notes acquired directly from the Issuer or an affiliate of the Issuer, then the Issuer and the Guarantors shall, in lieu of (or, in the case of clause (iii), in addition to) conducting the Exchange Offer contemplated by
Section 2(a), use their respective commercially reasonable efforts to file under the Securities Act a “shelf” registration statement providing for the registration of, and the sale on a continuous or delayed basis by the holders of,
all of the Registrable Securities, pursuant to Rule 415 or any similar rule that may be adopted by the Commission (such filing, the “Shelf Registration” and such registration statement, the
“Shelf Registration Statement”). The Issuer and the Guarantors agree to use their respective commercially reasonable efforts to cause the Shelf Registration Statement to become or be declared effective no later
than 90 days after such Shelf Registration Statement filing obligation arises; provided, that if at any time the Issuer is or becomes a “well-known seasoned issuer” (as defined in Rule 405) and is eligible to file an “automatic
shelf registration statement” (as defined in Rule 405), then the Issuer and the Guarantors shall file the Shelf Registration Statement in the form of an automatic shelf registration statement as provided in Rule 405. The Issuer and the
Guarantors agree to use their respective commercially reasonable efforts to keep such Shelf Registration Statement continuously effective for a period ending on the earlier of (a) one year after the date the Shelf Registration Statement is
declared effective and (b) the date on which all Registrable Securities registered thereunder are disposed of in accordance therewith (the “Shelf Registration Period”). No holder shall be entitled to be named as a
selling securityholder in the Shelf Registration Statement or to use the prospectus forming a part thereof for resales of Registrable Securities unless such holder is an Electing Holder. The Issuer and the Guarantors agree, after the Effective Time
of the Shelf Registration Statement and until the end of the Shelf Registration Period, promptly upon the request of any holder of Registrable Securities that is not then an Electing Holder, to use their respective commercially reasonable efforts to
enable such holder to use the prospectus forming a part thereof for resales of Registrable Securities, including, without limitation, any action necessary to identify such holder as a selling securityholder in the Shelf Registration Statement
(whether by post-effective amendment thereto or by filing a prospectus pursuant to Rules 430B and 424(b) under the Securities Act identifying such holder), provided, however, that nothing in this sentence shall relieve any such holder of the
obligation to return a completed and signed Notice and Questionnaire to the Issuer in accordance with Section 3(d)(iii). Notwithstanding anything to the contrary in this Section 2(b), upon notice to

  
 - 7 -

 
the Electing Holders, the Issuer may suspend the use or the effectiveness of such Shelf Registration Statement, or extend the time period in which it is required to file the Shelf Registration
Statement, for up to 30 consecutive days and up to 75 days in the aggregate, in each case in any 12-month period (each a “Suspension Period”) if the Board of Directors of the Issuer determines reasonably and in
good faith that there is a valid business purpose for suspension of the Shelf Registration Statement; provided that the Issuer shall use its commercially reasonable efforts to promptly notify the Electing Holders when the Shelf Registration
Statement may once again be used or is effective. 
 (c) In the event that (i) the Shelf Registration
Statement has not become effective or been declared effective by the Commission on or before the date on which such registration statement is required to become or be declared effective pursuant to Section 2(b), (ii) the Exchange Offer has
not been completed within 365 days following the Closing Date (if the Exchange Offer is then required to be made) or (iii) the Shelf Registration Statement required by Section 2(b) is filed and declared effective but shall thereafter
either be withdrawn by the Issuer or shall become subject to an effective stop order issued pursuant to Section 8(d) of the Securities Act suspending the effectiveness of such registration statement (except as specifically permitted herein,
including during any applicable Suspension Period in accordance with the last sentence of Section 2(b)) without being succeeded immediately by an additional registration statement filed and declared effective (each such event referred to in
clauses (i) through (iii), as further specified in this Section 2, a “Registration Default” and each period during which a Registration Default has occurred and is continuing, a
“Registration Default Period”), then, as liquidated damages for such Registration Default, subject to the provisions of Section 9(b), special interest (“Special
Interest”), in addition to the Base Interest, shall accrue on all Registrable Securities then outstanding (but, following the completion of the Exchange Offer, only on the principal amount of such Notes that could not be
exchanged as specified or were not exchanged as specified in Section 2(a)) at a per annum rate of 0.25% and shall increase at a per annum rate of 0.25% on the date that is 90 days after the Registration Default date for each subsequent 90-day
period that such Special Interest continues to accrue; provided that the rate at which Special Interest accrues may in no event exceed 1.00% per annum (such Special Interest to be calculated by the Issuer). Special Interest shall accrue
and be payable only with respect to a single Registration Default at any given time, notwithstanding the fact that multiple Registration Defaults may exist at such time. The payment of Special Interest shall be the sole and exclusive monetary remedy
available to the holders of the Registrable Securities for any Registration Default. Notwithstanding any other provision of this Section 2(c), (A) no such Special Interest shall accrue during a Suspension Period permitted by
Section 2(b) and (B) a holder (including, for the avoidance of doubt, any holder that is a broker-dealer) that is not entitled to the benefits of a Shelf Registration shall not be entitled to Special Interest with respect to any
Registration Default that pertains to such Shelf Registration. 
 (d) The Issuer shall take, and shall cause each
of the Guarantors to take, all actions necessary or advisable to be taken by it to ensure that the transactions contemplated herein are effected as so contemplated, including all actions necessary to register the Guarantees under any Exchange Offer
Registration Statement or Shelf Registration Statement, as applicable, on the terms set forth herein. 
 (e) Any
reference herein to a registration statement or prospectus as of any time shall be deemed to include any document incorporated, or deemed to be incorporated, therein by reference as of such time; and any reference herein to any post-effective
amendment to a registration statement or to any prospectus supplement as of any time shall be deemed to include any document incorporated, or deemed to be incorporated, therein by reference as of such time.

 3. Registration Procedures. 

If the Issuer and Guarantors file a registration statement pursuant to Section 2(a) or Section 2(b), the following provisions
shall apply: 
 (a) At or before the Effective Time of the Exchange Registration or any Shelf Registration,
whichever may occur first, the Issuer shall qualify the Indenture under the Trust Indenture Act. 
 (b) In the
event that such qualification would require the appointment of a new trustee under the Indenture, the Issuer shall appoint a new trustee thereunder pursuant to the applicable provisions of the Indenture. 

(c) In connection with the Issuer’s and the Guarantors’ obligations with respect to the registration of Exchange
Securities as contemplated by Section 2(a) (the “Exchange Registration”), if applicable, prior to the expiration of the Resale Period the Issuer and the Guarantors shall: 

(i) use their respective commercially reasonable efforts to prepare and file with the Commission an Exchange Offer
Registration Statement on any form which may be utilized by the Issuer and which shall permit the Exchange Offer and resales of Exchange Securities by broker-dealers during the Resale Period to be effected as contemplated by Section 2(a), and
use their respective commercially reasonable efforts to cause such Exchange Offer Registration Statement to become effective; 
 (ii) as soon as practicable use their respective commercially reasonable efforts to prepare and file with the Commission such amendments and supplements to such Exchange Offer Registration Statement and
the prospectus included therein as may be necessary to effect and maintain the effectiveness of such Exchange Offer Registration Statement for the periods and purposes contemplated in Section 2(a) and as may be required by the applicable rules
and regulations of the Commission and the instructions applicable to the form of such Exchange Offer Registration Statement, and promptly provide each broker-dealer holding Exchange Securities with such number of copies of the prospectus included
therein (as then amended or supplemented), in conformity in all material respects with the requirements of the Securities Act and the Trust Indenture Act, as such broker-dealer reasonably may request prior to the expiration of the Resale Period, for
use in connection with resales of Exchange Securities; 
 (iii) during the Resale Period, promptly notify each
broker-dealer that has requested or received copies of the prospectus included in such Exchange Offer Registration Statement, and confirm such advice in writing, (A) when such Exchange Offer Registration Statement or the prospectus included
therein or any prospectus amendment or supplement or post-effective amendment has been filed, and, with respect to such Exchange Offer Registration Statement or any post-effective amendment, when the same has become effective, (B) of any
comments by the Commission and by the blue sky or securities commissioner or regulator of any state with respect thereto or any request by the Commission for amendments or supplements to such Exchange Offer Registration Statement or prospectus or
for additional information, (C) of the issuance by the Commission of any stop order

suspending the effectiveness of such Exchange Offer Registration Statement or the initiation or threatening of any proceedings for that purpose, (D) if at any time the representations and
warranties of the Issuer contemplated by Section 5 cease to be true and correct in all material respects, (E) of the receipt by the Issuer of any notification with respect to the suspension of the qualification of the Exchange Securities
for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose, (F) the occurrence of any event that causes the Issuer to become an “ineligible issuer” as defined in Rule 405, or (G) when a
prospectus is required to be delivered under the Securities Act, that such Exchange Offer Registration Statement, prospectus, prospectus amendment or supplement or post-effective amendment does not conform in all material respects to the applicable
requirements of the Securities Act and the Trust Indenture Act or contains 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 made therein, in the light of the
circumstances under which they were made, not misleading;

Securities, Securities or Exchange Securities (as applicable) were registered under the Securities Act, or any preliminary, final or summary prospectus (including, without limitation, any “issuer free writing prospectus” as defined in Rule

and each such Electing Holder for any and all legal or other expenses reasonably incurred by them in connection with investigating or defending any such action or claim as such expenses are incurred;

Section 6, notify such indemnifying party in writing of the commencement of such action; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than
under the indemnification provisions of or contemplated by Section 6(a) or Section 6(b). In case any such action shall be brought against any indemnified party and it shall notify an indemnifying party of the commencement thereof,

  
 - 19 -

thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party
of its election so to assume the defense thereof, such indemnifying party shall not be liable to such indemnified party for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in

judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless
such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to, or an admission of, fault,
culpability or a failure to act by or on behalf of any indemnified party. 
 (d) Contribution. If for any
reason the indemnification provisions contemplated by Section 6(a) or Section 6(b) are unavailable to or insufficient (other than for the reasons specified in Section 6(a) or 6(b)) to hold harmless an indemnified party in respect of
any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or
liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party in connection with the statements or omissions which resulted in such losses, claims,
damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative fault of such indemnifying party and indemnified party shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by such indemnifying party or by such indemnified party, and the parties’ relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this Section 6(d) were determined by pro rata allocation (even
if the holders were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 6(d). The amount paid or payable by an indemnified party as
a result of the losses, claims, damages, or liabilities (or actions in respect thereof) referred to above shall be deemed to include any legal or other fees or expenses reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. Notwithstanding the provisions of this Section 6(d), no Electing Holder shall be required to contribute any amount in excess of the amount by which the dollar amount of the proceeds received by such holder
from the sale of any Registrable Securities (after deducting any fees, discounts and commissions applicable thereto) exceeds the amount of any damages which such holder has otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. The holders’ obligations in this Section 6(d) to contribute shall be several in proportion to the principal amount of Registrable Securities registered by them and not joint.

 (e) The obligations of the Issuer and the Guarantors under this
Section 6 shall be in addition to any liability which the Issuer or the Guarantors may otherwise have and shall extend, upon the same terms and conditions, to each officer, director and partner of each holder, each Electing Holder, and each
person, if any, who controls any of the foregoing within the meaning of the Securities Act; and the obligations of the holders and the Electing Holders contemplated by this Section 6 shall be in addition to any liability which the respective
holder or Electing Holder may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Issuer or the Guarantors (including any person who, with his consent, is named in any registration statement as
about to become a director of the Issuer or any of the Guarantors) and to each person, if any, who controls the Issuer within the meaning of the Securities Act, as well as to each officer and director of the other holders and to each person, if any,
who controls such other holders within the meaning of the Securities Act. 
 7. Underwritten Offerings. 

Each holder of Registrable Securities hereby agrees with the Issuer and each other such holder that no holder of Registrable Securities
may participate in any underwritten offering hereunder unless (a) the Issuer gives its prior written consent to such underwritten offering, (b) the managing underwriter or underwriters thereof shall be designated by Electing Holders
holding at least a majority in aggregate principal amount of the Registrable Securities to be included in such offering, provided that such designated managing underwriter or underwriters is or are reasonably acceptable to the Issuer,
(c) each holder of Registrable Securities participating in such underwritten offering agrees to sell such holder’s Registrable Securities on the basis provided in any underwriting arrangements approved by the persons entitled selecting the
managing underwriter or underwriters hereunder and (d) each holder of Registrable Securities participating in such underwritten offering completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and
other documents reasonably required under the terms of such underwriting arrangements. The Issuer hereby agrees with each holder of Registrable Securities that, to the extent it consents to an underwritten offering hereunder, it will negotiate in
good faith and execute all indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements, including using its commercially reasonable efforts to procure customary legal opinions and
auditor “comfort” letters. 
 8. Rule 144. 

(a) Facilitation of Sales Pursuant to Rule 144. The Issuer covenants to the holders of Registrable Securities that
to the extent it shall be required to do so under the Exchange Act (and unless it otherwise files such reports pursuant to the terms of the Indenture), the Issuer shall timely file the reports required to be filed by it under the Exchange Act or the
Securities Act (including the reports under Sections 13 and 15(d) of the Exchange Act referred to in subparagraph (c)(1) of Rule 144), 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 limitations of the exemption provided by Rule 144. 
 (b)
Availability of Rule 144 Not Excuse for Obligations under Section 2. The fact that holders of Registrable Securities may become eligible to sell such Registrable Securities pursuant to Rule 144 shall not (1) cause such Securities to
cease to be Registrable Securities for purpose of the Exchange Offer (other than as provided in the definition of “Registrable Securities” in Section 1) or (2) excuse the Issuer’s and the Guarantors’ obligations set
forth in Section 2 of this Agreement, including without limitation the obligations in respect of an Exchange Offer, Shelf Registration and Special Interest. 

  
 - 21 -

 9. Miscellaneous. 

(a) No Inconsistent Agreements. The Issuer represents, warrants, covenants and agrees that it has not granted, and
shall not grant, registration rights with respect to Registrable Securities, Exchange Securities or Securities, as applicable, or any other securities which would be inconsistent with the terms contained in this Agreement. 

(b) Specific Performance. The parties hereto acknowledge that there would be no adequate remedy at law if the
Issuer fails to perform any of its obligations hereunder and that the Purchasers and the holders from time to time of the Registrable Securities may be irreparably harmed by any such failure, and accordingly agree that the Purchasers and such
holders, in addition to any other remedy to which they may be entitled at law or in equity, shall be entitled to compel specific performance of the obligations of the Issuer under this Agreement in accordance with the terms and conditions of this
Agreement, in any court of the United States or any state thereof having jurisdiction. Time shall be of the essence in this Agreement. 
 (c) Notices. All notices, requests, claims, demands, waivers and other communications hereunder shall be in writing and shall be deemed to have been duly given when delivered by hand, if delivered
personally, by facsimile or by courier, or three days after being deposited in the mail (registered or certified mail, postage prepaid, return receipt requested) as follows: If to Merger Sub, to it at c/o TPG Capital, 345 California Street, San
Francisco, CA 94104, Attention: General Counsel, and if to the Company or any of the Guarantors, to it at Par Pharmaceutical Companies, Inc., 300 Tice Boulevard, Woodcliff Lake, New Jersey 07677, Attention: General Counsel, in each case, with a copy
to Ropes & Gray LLP, 800 Boylston Street, Boston, Massachusetts 02199, Attention: Patrick O’Brien, Esq. and if to a holder, to the address of such holder set forth in the security register or other records of the Issuer, or to such
other address as Merger Sub, the Company or any such holder may have furnished to the other in writing in accordance herewith, except that notices of change of address shall be effective only upon receipt thereof. 

(d) Parties in Interest. All the terms and provisions of this Agreement shall be binding upon, shall inure to the
benefit of and shall be enforceable by the parties hereto, the holders from time to time of the Registrable Securities (to the extent necessary to protect their rights hereunder) and the respective successors and assigns of the foregoing. In the
event that any transferee of any holder of Registrable Securities shall acquire Registrable Securities, in any manner, whether by gift, bequest, purchase, operation of law or otherwise, such transferee shall, without any further writing or action of
any kind, be deemed a beneficiary hereof for all purposes and such Registrable Securities shall be held subject to all of the terms of this Agreement, and by taking and holding such Registrable Securities such transferee shall be entitled to receive
the benefits of, and be conclusively deemed to have agreed to be bound by all of the applicable terms and provisions of this Agreement. If the Issuer shall so request, any such successor, assign or transferee shall agree in writing to acquire and
hold the Registrable Securities subject to all of the applicable terms hereof. 
 (e) Survival. The
respective indemnities, agreements, representations, warranties and each other provision set forth in this Agreement or made pursuant hereto shall remain in full force and effect regardless of any investigation (or statement as to the results
thereof) made by or on behalf of any holder of Registrable Securities, any director, officer or partner of such holder, or any controlling person of any of the foregoing, and shall survive delivery of and payment for the Registrable Securities
pursuant to the Purchase Agreement, the transfer and registration of Registrable Securities by such holder and the consummation of an Exchange Offer. 

  
 - 22 -

 (f) Governing Law; Jurisdiction; Waiver of Jury Trial. This
Agreement and any matters related to this transaction shall be governed by and construed in accordance with the laws of the State of New York without regard to principles of conflict of laws that would result in the application of any law other than
the laws of the State of New York. The Purchasers, Sky, the Company and each of the Guarantors agree that any suit or proceeding arising in respect of this Agreement will be tried exclusively in the U.S. District Court for the Southern District
of New York or, if that court does not have subject matter jurisdiction, in any state court located in The City and County of New York and the Purchasers, Sky, the Company and each of the Guarantors agree to submit to the jurisdiction of, and to
venue in, such courts. The Purchasers, Sky, the Company and the Guarantors hereby irrevocably waive, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this
Agreement or the transactions contemplated hereby. 
 (g) Headings. The descriptive headings of the
several Sections and paragraphs of this Agreement are inserted for convenience only, do not constitute a part of this Agreement and shall not affect in any way the meaning or interpretation of this Agreement. 

(h) Entire Agreement; Amendments. This Agreement and the other writings referred to herein (including the
Indenture, Registration Rights Agreement Joinder and the form of Securities) or delivered pursuant hereto which form a part hereof contain the entire understanding of the parties with respect to its subject matter. This Agreement supersedes all
prior agreements and understandings between the parties with respect to its subject matter. This Agreement may be amended and the observance of any term of this Agreement may be waived (either generally or in a particular instance and either
retroactively or prospectively) only by a written instrument duly executed by the Issuer and the holders of at least a majority in aggregate principal amount of the Registrable Securities at the time outstanding; provided that no consent is
necessary from any holder (including, for the avoidance of doubt, any holder that is a broker-dealer) in the event that this Agreement is amended, modified or supplemented for the purpose of curing any ambiguity, defect or inconsistency that does
not adversely affect the rights of any holder. Each holder of any Registrable Securities at the time or thereafter outstanding shall be bound by any amendment or waiver effected pursuant to this Section 9(h), whether or not any notice, writing
or marking indicating such amendment or waiver appears on such Registrable Securities or is delivered to such holder. 
 (i) Counterparts. This Agreement may be executed by the parties in counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one
and the same instrument. 
 (j) Severability. If any provision of this Agreement, or the application
thereof in any circumstance, is held to be invalid, illegal or unenforceable in any respect for any reason, the validity, legality and enforceability of such provision in every other respect and of the remaining provisions contained in this
Agreement shall not be affected or impaired thereby. 
 (k) Enforceability. Notwithstanding anything
herein to the contrary, or in any of the Registration Rights Agreement Joinder, the Purchase Agreement, the Joinder Agreement, the Indenture, or the Securities, unless and until the Merger is consummated, none of the Company or any of the Guarantors
shall have any obligation or liability arising thereunder or under or related to this Agreement; provided, that immediately upon the consummation of the Merger, each of the Company and the Guarantors expressly assumes its obligations
hereunder and thereunder. Notwithstanding anything herein to the contrary, any failure by the Company or any Guarantor to become a signatory to each of the Joinder Agreement and the Registration Rights Agreement Joinder shall not relieve Merger Sub
(and its successors) of any of its obligations hereunder or under the Purchase Agreement, as the case may be.

 If the foregoing is in accordance with your understanding, please sign and
return to us six counterparts hereof, and upon the acceptance hereof by you, on behalf of each of the Purchasers, this letter and such acceptance hereof shall constitute a binding agreement between each of the Purchasers, Merger Sub, the Company and
the Guarantors. It is understood that your acceptance of this letter on behalf of each of the Purchasers is pursuant to the authority set forth in a form of Agreement among Purchasers, the form of which shall be submitted to the Issuer for
examination upon request, but without warranty on your part as to the authority of the signers thereof.

		 	(b)	  	Set forth below is Interpretation A.65 of the Commission’s July 1997 Manual of Publicly Available Interpretations regarding short selling:
			
		 		  	“An issuer filed a Form S-3 registration statement for a secondary offering of common stock which is not yet effective. One of the selling shareholders wanted to do a short
sale of common stock “against the box” and cover the short sale with registered shares after the effective date. The issuer was advised that the short sale could not be made before the registration statement becomes effective, because the
shares underlying the short sale are deemed to be sold at the time such sale is made. There would, therefore, be a violation of Section 5 if the shares were effectively sold prior to the effective date.”
			
		 		  	By returning this Notice and Questionnaire, the undersigned Selling Securityholder will be deemed to be aware of the foregoing interpretation.

*        *        *

 The Selling Securityholder hereby acknowledges its obligations under the Registration Rights Agreement to indemnify and hold harmless the Company and certain other persons as set forth in the Registration
Rights Agreement. 
 In the event that the Selling Securityholder transfers all or any portion of the Registrable Securities listed in Item
(3) above after the date on which such information is provided to the Company, the Selling Securityholder agrees to notify the transferee(s) at the time of the transfer of its rights and obligations under this Notice and Questionnaire and the
Registration Rights Agreement. 
 By signing below, the Selling Securityholder consents to the disclosure of the information contained herein in
its answers to Items (1) through (9) above and the inclusion of such information in the Shelf Registration Statement and related Prospectus. The Selling Securityholder understands that such information will be relied upon by the Company in
connection with the preparation of the Shelf Registration Statement and related Prospectus.
