2. Registration Under the Securities Act.

(a) Except as set forth in Section 2(b) below, the Company, Parent and the Subsidiary Guarantors agree to file under the Securities Act, no later than 120 days after the Closing Date, a registration statement relating to a registration statement (such registration statement, the “Exchange Registration Statement”) relating to an offer (the “Exchange Offer”) to issue debt securities (in like principal amount as the Securities) to be issued by the Company and guaranteed by Parent and the Subsidiary Guarantors, which debt securities and guarantee are substantially identical to the Securities and the related Guarantee, 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 Company, Parent and the Subsidiary Guarantors agree to use all commercially reasonable efforts to cause the Exchange Registration Statement to become effective under the Securities Act no later than 210 days after the Closing Date. The Exchange Offer will be registered under the Securities Act on the appropriate form and will 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 Company further agrees to use all commercially reasonable efforts to (i) commence the Exchange Offer promptly (but no later than 10 Business Days) following the Effective Time of such Exchange 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Act and (iii) exchange Exchange Securities for all Registrable Securities that have been properly tendered and not withdrawn promptly following the expiration of the Exchange Offer. The Exchange Offer will be deemed to have been “completed” only (i) if the debt securities and related guarantee 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 Company 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 and not more than 30 Business Days following the commencement of the Exchange Offer. The Company, Parent and the Subsidiary Guarantor agree (x) to include in the Exchange 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 Registration Statement effective for a period

(the “Resale Period”) beginning when Exchange Securities are first issued in the Exchange Offer and ending upon the earlier of the expiration of the 180^th 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 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 existing law or Commission interpretations are changed such that the debt securities or the related guarantee 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 Effective Time of the Exchange Registration Statement is not within 210 days following the Closing Date and the Exchange Offer has not been completed within 30 Business Days of such Effective Time or (iii) any holder of Registrable Securities notifies the Company prior to the 20^th 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 Registration Statement is not appropriate or available for such resales or (C) it is a broker-dealer and owns Securities acquired directly from the Company or an affiliate of the Company, then the Company, Parent and the Subsidiary Guarantors shall, in lieu of (or, in the case of clause (iii), in addition to) conducting the Exchange Offer contemplated by Section 2(a), file under the Securities Act no later than 30 days after the time such obligation to file arises (but no earlier than 120 days after the Closing Date), 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 Company, Parent and the Subsidiary Guarantors agree to use all 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 (but no earlier than 210 days after the Closing Date); provided, that if at any time the Company 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 Company, Parent and the Subsidiary Guarantors shall file the Shelf Registration Statement in the form of an automatic shelf registration statement as provided in Rule 405. The Company, Parent and the Subsidiary Guarantors agree to use all commercially reasonable efforts to keep such Shelf Registration Statement continuously effective for a period ending on the earlier of the second anniversary of the Effective Time or such time as there are no longer any Registrable Securities outstanding. 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 Company, Parent and the Subsidiary Guarantors agree, after the Effective Time of the Shelf Registration Statement and promptly upon the request of any holder of Registrable Securities that is not then an Electing Holder, to use all 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 Company in accordance with Section 3(d)(iii).

Notwithstanding anything to the contrary in this Section 2(b), upon notice to the Electing Holders, the Company 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 60 days in the aggregate, in each case in any 12-month period (a “Suspension Period”) if the Board of Directors of the Company determines that there is a valid business purpose for suspension of the Shelf Registration Statement; provided that the Company shall 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 Company, Parent and the Subsidiary Guarantors have not filed the Exchange Registration Statement or the Shelf Registration Statement on or before the date on which such registration statement is required to be filed pursuant to Section 2(a) or Section 2(b), respectively, or (ii) such Exchange Registration Statement or 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(a) or Section 2(b), respectively, or (iii) the Exchange Offer has not been completed within 30 Business Days after the Effective Time of the Exchange Registration Statement relating to the Exchange Offer (if the Exchange Offer is then required to be made) or (iv) any Exchange Registration Statement or Shelf Registration Statement required by Section 2(a) or Section 2(b) is filed and declared effective but shall thereafter either be withdrawn by the Company 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, with respect to any Shelf Registration Statement, 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 (iv), 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 at a per annum rate of 0.25% for the first 90 days of the Registration Default Period, at a per annum rate of 0.50% for the second 90 days of the Registration Default Period, at a per annum rate of 0.75% for the third 90 days of the Registration Default Period and at a per annum rate of 1.0% thereafter for the remaining portion of the Registration Default Period. 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.

(d) The Company shall take, and shall cause Parent and the Subsidiary 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 or desirable to register the Guarantees under any Exchange Registration Statement or Shelf Registration Statement, as applicable.

(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.

(xii) use all commercially reasonable efforts to (A) register or qualify the Registrable Securities to be included in such Shelf Registration Statement under such securities laws or blue sky laws of such jurisdictions as any Electing Holder shall reasonably request, (B) keep such registrations or qualifications in effect and comply with such laws so as to permit the continuance of offers, sales and dealings therein in such jurisdictions during the period the Shelf Registration Statement is required to remain effective under Section 2(b) and for so long as may be necessary to enable any such Electing Holder to complete its distribution of Registrable Securities pursuant to such Shelf Registration Statement, (C) take any and all other actions as may be reasonably necessary or advisable to enable each such Electing Holder to consummate the disposition in such jurisdictions of such Registrable Securities and (D) obtain the consent or approval of each governmental agency or authority, whether federal, state or local, which may be required to effect the Shelf Registration or the offering or sale in connection therewith or to enable the selling holder or holders to offer, or to consummate the disposition of, their Registrable Securities; provided, however, that neither the Company, Parent nor the Subsidiary Guarantors shall be required for any such purpose to (1) qualify as a foreign corporation in any jurisdiction wherein it would not otherwise be required to qualify but for the requirements of this Section 3(d)(xii), (2) consent to general service of process in any such jurisdiction or become subject to taxation in any such jurisdiction or (3) make any changes to its certificate of incorporation or by-laws or other governing documents or any agreement between it and its stockholders;

(b) Any documents incorporated by reference in any prospectus referred to in Section 5(a), when they become or became effective or are or were filed with the Commission, as the case may be, will conform or conformed in all material respects to the requirements of the Securities Act or the Exchange Act, as applicable, and none of such documents will contain or contained an untrue statement of a material fact or will omit or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading; provided, however, that this representation and warranty shall not apply to any statements or omissions made in reliance upon and in conformity with information furnished in writing to the Company by a holder of Registrable Securities expressly for use therein.

(c) The compliance by the Company with all of the provisions of this Agreement and the consummation of the transactions herein contemplated will not (i) conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the Company or any of its subsidiaries is a party or by which the Company or any of its subsidiaries is bound or to which any of the property or assets of the Company or any of its subsidiaries is subject, (ii) result in any violation of the provisions of the certificate of incorporation, as amended, or the by-laws or other governing documents, as applicable, of the Company, Parent or the Subsidiary Guarantors or (iii) result in any violation of any statute or any order, rule or regulation of any court or governmental agency or body having jurisdiction over the Company or any of its subsidiaries or any of their respective properties, except in the case of clauses (i) and (iii) as would not reasonably be expected to have a

6. Indemnification and Contribution.

(a) Indemnification by the Company, Parent and the Subsidiary Guarantors. The Company, Parent and the Subsidiary Guarantors, jointly and severally, will indemnify and hold harmless each of the holders of Registrable Securities included in an Exchange Registration Statement and each of the Electing Holders as holders of Registrable Securities included in a Shelf Registration Statement against any losses, claims, damages or liabilities, joint or several, to which such holder or such Electing Holder may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Exchange Registration Statement or any Shelf Registration Statement, as the case may be, under which such Registrable or Exchange Securities 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 433) contained therein or furnished by the Company to any such holder or any such Electing Holder, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each such holder 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; provided, however, that neither the Company, Parent nor the Subsidiary Guarantors shall be liable to any such person in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement, or preliminary, final or summary prospectus (including, without limitation, any “issuer free writing prospectus” as defined in Rule 433), or amendment or supplement thereto, in reliance upon and in conformity with written information furnished to the Company by such person expressly for use therein.

(b) Indemnification by the Electing Holders. The Company may require, as a condition to including any Registrable Securities in any Shelf Registration Statement filed pursuant to Section 2(b), that the Company shall have received an undertaking reasonably satisfactory to it from each Electing Holder of Registrable Securities included in such Shelf Registration Statement, severally and not jointly, to (i) indemnify and hold harmless the Company, Parent, the Subsidiary Guarantors and all other Electing Holders of Registrable Securities included in such Shelf Registration Statement, against any losses, claims, damages or liabilities to

which the Company, Parent, the Subsidiary Guarantors or such other Electing Holders may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in such registration statement, or any preliminary, final or summary prospectus (including, without limitation, any “issuer free writing prospectus” as defined in Rule 433) contained therein or furnished by the Company to any Electing Holder, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by such Electing Holder expressly for use therein, and (ii) reimburse the Company, Parent and the Subsidiary Guarantors for any legal or other expenses reasonably incurred by the Company, Parent and the Subsidiary Guarantors in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that no such Electing Holder shall be required to undertake liability to any person under this Section 6(b) for any amounts in excess of the dollar amount of the proceeds to be received by such Electing Holder from the sale of such Electing Holder’s Registrable Securities pursuant to such registration.

(c) Notices of Claims, Etc. Promptly after receipt by an indemnified party under subsection (a) or (b) above of written notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party pursuant to the indemnification provisions of or contemplated by this 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, such indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense 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 connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the prior written consent of the indemnified party (which consent shall not be unreasonably delayed or withheld), effect the settlement or compromise of, or consent to the entry of any 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 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 vis-à-vis other holders 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 Company, Parent and the Subsidiary Guarantors under this Section 6 shall be in addition to any liability which the Company, Parent or the Subsidiary 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 Company, Parent or the Subsidiary Guarantors (including any person who, with his consent, is named in any registration statement as about to become a director of the Company, Parent or the Subsidiary Guarantors) and to each person, if any, who controls the Company 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 Company and each other such holder that no holder of Registrable Securities may participate in any underwritten offering hereunder unless (a) the Company 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 Company, (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 Company 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 all commercially reasonable efforts to procure customary legal opinions and auditor “comfort” letters.

8. Rule 144.

(a) Facilitation of Sales Pursuant to Rule 144. The Company covenants to the holders of Registrable Securities that to the extent it shall be required to do so under the Exchange Act, the Company 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), and shall take such further action as any holder of Registrable Securities may reasonably request, 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. Upon the request of any holder of Registrable Securities in connection with that holder’s sale pursuant to Rule 144, the Company shall deliver to such holder a written statement as to whether it has complied with such requirements.

(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 or (2) excuse the Company’s, Parent’s and the Subsidiary 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.

9. Miscellaneous.

(a) No Inconsistent Agreements. The Company 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 Company 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 Company 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

		(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.

By signing below, the Selling Securityholder acknowledges that it understands its obligation to comply, and agrees that it will comply, with the provisions of the Exchange Act, particularly Regulation M (or any successor rule or regulation).

The Selling Securityholder hereby acknowledges its obligations under the Exchange and Registration Rights Agreement to indemnify and hold harmless the Company and certain other persons as set forth in the Exchange and 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.

In accordance with the Selling Securityholder’s obligation under Section 3(d) of the Exchange and Registration Rights Agreement to provide such information as may be required by law for inclusion in the Shelf Registration Statement, the Selling Securityholder agrees to promptly notify the Company of any inaccuracies or changes in the information provided herein which may occur subsequent to the date hereof at any time while the Shelf Registration Statement remains in effect and to provide such additional information that the Company may reasonably request regarding such Selling Securityholder and the intended method of distribution of Registrable Securities in order to comply with the Securities Act.
