1 Exhibit 4.15 ------------ BUILDING MATERIALS CORPORATION OF AMERICA $35,000,000 10.50% Senior Notes Due 2002 REGISTRATION RIGHTS AGREEMENT July 5, 2000 BNY Capital Markets, Inc. One Wall Street New York, New York 10286 Ladies and Gentlemen: Building Materials Corporation of America, a Delaware corporation (the "Company"), proposes to issue and sell to you (the "Initial Purchaser"), upon the terms set forth in a purchase agreement dated June 28, 2000 (the "Purchase Agreement"), $35,000,000 aggregate principal amount of its 10.50% Senior Notes due 2002 (the "Notes"). The Subsidiaries of the Company listed on the signature pages hereto (the "Guarantors", and, together with the Company, the "Issuers") will jointly and severally guarantee the Notes (the "Guarantees" and the Notes, as so guaranteed, the "Securities"). The Securities will be issued pursuant to an indenture (the "Indenture") among the Company, the Guarantors and The Bank of New York, as trustee (the "Trustee") dated July 5, 2000, substantially in the form previously furnished to the Initial Purchaser. As an inducement to the Initial Purchaser, the Issuers agree with the Initial Purchaser, for the benefit of the holders of the Securities (including, without limitation, the Initial Purchaser, herein referred to as the "Holders"), as follows: 1. Registered Exchange Offer. The Company shall prepare and, by the earlier of 90 days after the date of original issuance of the Securities (the "Issue Date") and the date of filing of a registration statement in respect of an initial public offering of common stock of the Company (other than a registration statement on Form S-8), file with the Securities and Exchange Commission (the "Commission") a registration statement (the "Exchange Offer Registration Statement") on an appropriate form under the Securities Act of 1933, as amended (the "Securities Act"), with respect to a proposed offer (the "Registered Exchange Offer") to the Holders of the Securities to issue and deliver to such Holders, in exchange for the Securities, a like principal amount of debt securities of the Company guaranteed by the Guarantors identical in all material respects to the Securities (the "Exchange Notes"), except for the transfer restrictions relating to the Securities. The Issuers shall use their best efforts to cause such Exchange Offer Registration Statement to become effective under the Securities Act within 180 days of the Issue Date. Following the declaration of the effectiveness of the Exchange Offer Registration Statement, the Issuers shall promptly commence the Registered Exchange Offer, it being the objective of such Registered Exchange Offer to enable each Holder of 2 the Securities electing to exchange the Securities for Exchange Notes and (assuming that such Holder is not an affiliate of the Company within the meaning of the Securities Act, acquires the Exchange Notes in the ordinary course of such Holder's business and has no arrangements with any person to participate in the distribution of the Exchange Notes) to trade such Exchange Notes from and after their receipt without any limitations or restrictions under the Securities Act and the securities laws of the several states of the United States. In connection with such Registered Exchange Offer, the Issuers shall take such further action, including, without limitation, appropriate filings under state securities laws, as may be necessary to realize the foregoing objective subject to the proviso of Section 3(h). The Issuers shall include within the prospectus contained in the Exchange Offer Registration Statement a section entitled "Plan of Distribution", reasonably acceptable to the Initial Purchaser, which shall contain a summary statement of the positions taken or policies made by the staff of the Commission with respect to the potential "underwriter" status of any broker-dealer that is the beneficial owner (as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the "Exchange Act")) of Exchange Notes received by such broker-dealer in the Registered Exchange Offer (a "Participating Broker-Dealer"), whether such positions or policies have been publicly disseminated by the staff of the Commission or such positions or policies, in the reasonable judgment of the Initial Purchaser, represent the prevailing views of the staff of the Commission. Such "Plan of Distribution" section shall also allow the use of the prospectus by all persons subject to the prospectus delivery requirements of the Securities Act, including Participating Broker-Dealers, and include a statement describing the means by which Participating Broker-Dealers may resell the Exchange Notes. The Issuers shall use their best efforts to keep the Exchange Offer Registration Statement effective and to amend and supplement the prospectus contained therein, in order to permit such prospectus to be lawfully delivered by all persons subject to the prospectus delivery requirements of the Securities Act for such period of time as such persons must comply with such requirements in order to resell the Exchange Notes; provided that such period shall not exceed 180 days (or such longer period if extended pursuant to Section 3(j) below). If, upon consummation of the Exchange Offer, the Initial Purchaser holds Securities acquired by it as part of its initial distribution, the Company upon the request of the Initial Purchaser shall simultaneously with the delivery of the Exchange Notes pursuant to the Registered Exchange Offer issue and deliver to the Initial Purchaser, in exchange (the "Private Exchange") for the Securities held by the Initial Purchaser, a like principal amount of debt securities of the Company guaranteed by the Guarantors identical in all material respects to the Securities (the "Private Exchange Notes"). The Private Exchange Notes shall bear the same CUSIP number as the Exchange Notes. In connection with the Registered Exchange Offer, the Issuers shall: (a) mail to each Holder a copy of the prospectus forming part of the Exchange Offer Registration Statement, together with an appropriate letter of transmittal and related documents; 2 3 (b) keep the Registered Exchange Offer open for not less than 20 business days after the date notice thereof is mailed to the Holders (or longer if required by applicable law); (c) utilize the services of a depository for the Registered Exchange Offer with an address in the Borough of Manhattan, The City of New York; (d) permit Holders to withdraw tendered Securities at any time prior to the close of business, New York time, on the last business day on which the Registered Exchange Offer shall remain open; and (e) otherwise comply in all respects with all applicable laws. As soon as practicable after the close of the Registered Exchange Offer or the Private Exchange, as the case may be, the Issuers shall: (i) accept for exchange all the Securities tendered and not validly withdrawn pursuant to the Registered Exchange Offer and the Private Exchange; (ii) deliver to the Trustee for cancellation all the Securities so accepted for exchange; and (iii) cause the Trustee to authenticate and deliver promptly to each Holder of the Securities, Exchange Notes or Private Exchange Notes, as the case may be, equal in principal amount to the Securities of such Holder so accepted for exchange. The Exchange Notes and the Private Exchange Notes may be issued under (i) the Indenture or (ii) an indenture substantially similar to the Indenture, which in either event will provide that the Exchange Notes will not be subject to the transfer restrictions set forth in the Indenture and that the Exchange Notes, the Private Exchange Notes and the Securities will vote and consent together on all matters as one class and that none of the Exchange Notes, the Private Exchange Notes or the Securities will have the right to vote or consent as a separate class on any matter. 2. Shelf Registration. If, (i) because of any change in law or in currently prevailing interpretations of the staff of the Commission, the Issuers are not permitted to effect a Registered Exchange Offer, as contemplated by Section 1 hereof, (ii) for any reason the Registered Exchange Offer is not completed within 210 days of the Issue Date (the "Initial Completion Deadline"), which date shall be extended for an additional 30 days upon delivery prior to the Initial Completion Deadline of a certificate of the Company to the effect that the Registered Exchange Offer is scheduled to be completed within 30 days of the Initial Completion Deadline (the "Extended Completion Deadline"), (iii) the Initial Purchaser so requests with respect to the Securities or the Private Exchange Notes held by it following consummation of the Registered Exchange Offer or (iv) any Holder is not eligible to participate in the Registered 3 4 Exchange Offer or, in the case of any Holder that participates in the Registered Exchange Offer or the Private Exchange, such Holder does not receive freely tradable Exchange Notes on the date of the exchange, the Issuers shall, at their cost, take the following actions: (a) as promptly as reasonably practicable file with the Commission and thereafter shall use their best efforts to cause to be declared effective a registration statement (the "Shelf Registration Statement" and, together with the Exchange Offer Registration Statement, a "Registration Statement") on an appropriate form under the Securities Act relating to the offer and sale of the Securities or, if applicable, the Private Exchange Notes by the Holders thereof from time to time in accordance with the methods of distribution set forth in the Shelf Registration Statement and Rule 415 under the Securities Act (hereafter, the "Shelf Registration"). (b) use their best efforts to keep the Shelf Registration Statement continuously effective in order to permit the prospectus included therein to be lawfully delivered by the Holders of the Securities or, if applicable, the Private Exchange Notes for a period of two years (or for such longer period if extended pursuant to Section 3(j) below) from the Issue Date or such shorter period that will terminate when all the Securities or, if applicable, the Private Exchange Notes covered by the Shelf Registration Statement have been sold pursuant thereto; provided, that the Issuers shall be deemed not to have used their best efforts to keep the Shelf Registration Statement effective during the requisite period if it voluntarily takes any action that would result in Holders of the Securities or, if applicable, the Private Exchange Notes covered thereby not being able to offer and sell the Securities or, if applicable, the Private Exchange Notes during that period, unless such action is required by applicable law. (c) Notwithstanding any other provisions of this Agreement to the contrary, the Issuers shall cause the Shelf Registration Statement and the related prospectus and any amendment or supplement thereto, as of the effective date of the Shelf Registration Statement, amendment or supplement, (i) to comply in all material respects with the applicable requirements of the Securities Act and the rules and regulations of the Commission and (ii) not to contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. 3. Registration Procedures. In connection with any Shelf Registration contemplated by Section 2 hereof and, to the extent applicable, any Registered Exchange Offer contemplated by Section 1 hereof, the following provisions shall apply: (a) The Company shall furnish to the Initial Purchaser, prior to the filing thereof with the Commission, a copy of the Registration Statement and each amendment thereof and each supplement, if any, to the prospectus included therein and shall obtain the consent of the Initial Purchaser to any such filing, which shall not be unreasonably withheld. (b) The Company shall give written notice to the Initial Purchaser, the Holders of the Securities and any Participating Broker-Dealer 4 5 from whom the Company has received prior written notice that it will be a Participating Broker-Dealer in the Registered Exchange Offer: (i) when the Registration Statement or any amendment thereto has been filed with the Commission and when the Registration Statement or any post-effective amendment thereto has become effective; (ii) of any request by the Commission for amendments or supplements to the Registration Statement or the prospectus included therein or for additional information, provided that the request and the contents of the request need only be disclosed to the Initial Purchaser and one counsel appointed by and on behalf of the Holders of the Securities as described in Section 4; (iii) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose; (iv) of the receipt by any Issuer or its legal counsel of any notification with respect to the suspension of the qualification of the Securities or, if applicable, the Private Exchange Notes for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and (v) of the happening of any event that requires the Issuers to make changes in the Registration Statement or the prospectus in order to make the statements therein not misleading (which notice shall be accompanied by an instruction to suspend the use of the prospectus until the requisite changes have been made). (c) The Issuers shall use their best efforts to prevent the issuance or obtain the withdrawal of any order suspending the effectiveness of the Registration Statement at the earliest possible time. (d) The Company shall furnish to each Holder of the Securities or, if applicable, the Private Exchange Notes included within the coverage of the Shelf Registration, without charge, at least one copy of the Registration Statement and any post-effective amendment thereto, including financial statements and schedules, and, if the Holder so requests in writing, all exhibits (including those, if any, incorporated by reference). (e) The Company shall deliver to the Initial Purchaser and to any other Holder who so requests, without charge, at least one copy of the Exchange Offer Registration Statement and any post-effective amendment thereto, including financial statements and schedules, and, if the Initial Purchaser or any such Holder requests, all exhibits (including those incorporated by reference).

The Issuers consent, subject to the provisions of this Agreement, to the use of the prospectus or any amendment or supplement thereto by each of the selling Holders of the Securities or, if applicable, the Private Exchange Notes in connection with the offering and sale of the Securities or, if applicable, the Private Exchange Notes covered by the prospectus, or any amendment or supplement thereto, included in the Shelf Registration Statement.

The Issuers consent, subject to the provisions of this Agreement, to the use of the prospectus or any amendment or supplement thereto by the Initial Purchaser, if necessary, any Participating Broker-Dealer and such other persons required to deliver a prospectus following the Registered Exchange Offer in connection with the offering and sale of the Exchange Notes covered by the prospectus, or any amendment or supplement thereto, included in such Exchange Offer Registration Statement. (h) Prior to any public offering of the Securities or, if applicable, the Private Exchange Notes, pursuant to the Shelf Registration, the Company shall register or qualify or cooperate with the Holders of the Securities or, if applicable, the Private Exchange Notes, included therein and their respective counsel in connection with the registration or qualification of the Securities or, if applicable, the Private Exchange Notes, for offer and sale under the securities or blue sky laws of such jurisdictions as any Holder of the Securities or the Private Exchange Notes reasonably requests in writing and do any and all other acts or things necessary or advisable to enable the offer and sale in such jurisdictions of the Securities covered by the Shelf Registration; provided that the Issuers shall not be required to (i) qualify generally to do business in any jurisdiction where it is not then so qualified or (ii) take any action which would subject it to general service of process or to taxation in any jurisdiction where it is not then so subject. (i) The Issuers shall cooperate with the Holders of the Securities or, if applicable, the Private Exchange Notes to facilitate the timely preparation and delivery of certificates representing the Securities or, if applicable, the Private Exchange Notes to be sold in the Shelf Registration free of any restrictive legends and in such denominations and registered in such names as the Holders may request a reasonable period of time prior to sales of the Securities or, if applicable, the Private Exchange Notes pursuant to the Shelf Registration. (j) Upon the occurrence of any event contemplated by Section 3(b)(v) above, the Issuers shall promptly prepare a post-effective amendment to the Registration Statement or a supplement to the related prospectus or file any other required document so that, as thereafter 6 7 delivered to Holders of the Securities, the Exchange Notes or, if applicable, the Private Exchange Notes, as the case may be, the prospectus will not contain an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. If the Company notifies the Initial Purchaser, the Holders of the Securities and any known Participating Broker-Dealer in accordance with Section 3(b)(v) above to suspend the use of the prospectus until the requisite changes to the prospectus have been made, then the Initial Purchaser, the Holders of the Securities and any such Participating Broker-Dealers shall suspend use of such prospectus, and the period of effectiveness of the Shelf Registration Statement provided for in Section 2(b) above and the Exchange Offer Registration Statement provided for in Section 1 above shall each be extended by the number of days from and including the date of the giving of such notice to Holders of the Securities and any known Participating Broker-Dealer shall have received such amended or supplemented prospectus pursuant to this Section 3(j).

(m) The Issuers shall cause the Indenture (or an indenture substantially identical to the Indenture in the case of a Registered Exchange Offer) to be qualified under the Trust Indenture Act of 1939, as amended. (n) The Company may require each Holder of the Securities to be sold pursuant to the Shelf Registration Statement to furnish to the Company such information regarding the Holder and the distribution of the Securities as the Company may from time to time reasonably require for inclusion in the Shelf Registration Statement.

Indemnification. (a) The Issuers agree to indemnify and hold harmless each Holder of the Securities or, if applicable, the Private Exchange Notes 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 and each director, officer, employee or agent of such Holder and each director, officer, employee or agent of each such controlling person (each Holder, such controlling persons and each such director, officer, employee and agent are referred to collectively as the "Indemnified Parties") from and against any losses, claims, damages or liabilities, joint or several, or any actions in respect thereof (including, but not limited to, any losses, claims, damages, liabilities or actions relating to purchases and sales of the Securities or, if applicable, the Private Exchange Notes), to which each Indemnified Party may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in a Registration Statement or prospectus or in 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, in light of the circumstances under which they were made, not misleading, and shall reimburse, as incurred, the Indemnified Parties for any legal or other expenses reasonably incurred by them in connection with investigating or defending or preparing to defend against or appearing as a third-party witness in connection with any such loss, claim, damage, liability or action in respect thereof; provided, however, that the Issuers shall not be liable in any such case to the extent that such loss, claim, damage or liability arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in a Registration Statement or prospectus or in any amendment or supplement thereto or in any preliminary prospectus relating to a Shelf Registration in reliance upon and in conformity with written information furnished to any Issuer by or on behalf of such Holder specifically for inclusion therein; provided, further , that (A) the Issuers shall not be obligated to indemnify or hold harmless any Indemnified Party in respect of any loss, claim, damage, liability or action to the extent that any such loss, claim, damage, liability or action arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in a preliminary Registration Statement or preliminary prospectus if the applicable Holder or Initial Purchaser failed to deliver a copy of a final prospectus or an amended or supplemented Registration Statement or prospectus that was made available by the Issuers to such Indemnified Party prior to the applicable sale to the person or persons asserting the claim which is the basis of indemnification and such final prospectus or amended or supplemented Registration Statement or prospectus cured such defect and (B) this indemnity agreement will be in addition to any liability which the Company may otherwise have to such Indemnified Party. The Issuers will not settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action, suit or proceeding in respect of which indemnification may be sought hereunder (whether or not such Indemnified Party or any person who controls such Indemnified Party within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act is a party to such claim, action, suit or proceeding) without the prior written consent of such Indemnified Party, which consent shall not be unreasonably withheld, unless such settlement, compromise or consent includes an unconditional release of such 9 10 Indemnified Party and each such controlling person from all liability arising out of such claim, action, suit or proceeding. No Indemnified Party will settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action, suit or proceeding in respect of which indemnification may be sought without the prior written consent of the Issuers (which consent will not be unreasonably withheld). The Issuers shall also indemnify underwriters, selling brokers, dealer managers and similar securities industry professionals participating in the distribution (as described in such Registration Statement), their officers and directors and each person who controls such persons (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) to the same extent as provided above with respect to the indemnification of the Holders of the Securities if requested by such Holders. (b) The Issuers agrees to indemnify and hold harmless the Initial Purchaser, any Participating Broker-Dealer and each person, if any, who controls the Initial Purchaser or a Participating Broker-Dealer within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and each director, officer, employee or agent of the Initial Purchaser or a Participating Broker-Dealer and each director, officer, employee or agent of each such controlling person (the Initial Purchaser, any Participating Broker-Dealer, such controlling persons and each such director, officer, employee and agent of the Initial Purchaser, such Participating Broker-Dealer or such controlling person are referred to collectively as the "Exchange Offer Indemnified Parties") from and against any losses, claims, damages or liabilities, joint or several, or any actions in respect thereof (including, but not limited to, any losses, claims, damages, liabilities or actions relating to purchases and sales of Exchange Notes), to which each Exchange Offer Indemnified Party may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Exchange Offer Registration Statement or prospectus contained therein or in 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, in light of the circumstances under which they were made, not misleading, and shall reimburse, as incurred, the Exchange Offer Indemnified Parties for any legal or other expenses reasonably incurred by them in connection with investigating or defending or preparing to defend against or appearing as a third-party witness in connection with any such loss, claim, damage, liability or action in respect thereof; provided, however, that the Issuers shall not be liable in any such case to the extent that such loss, claim, damage or liability arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in any Exchange Offer Registration Statement or prospectus contained therein or in any amendment or supplement thereto in reliance upon and in conformity with written information furnished to any Issuer by or on behalf of the Initial Purchaser or 10 11 Participating Broker-Dealer specifically for inclusion therein; provided, further, that (A) the Issuers shall not be obligated to indemnify or hold harmless any Exchange Offer Indemnified Party in respect of any loss, claim, damage, liability or action to the extent that any such loss, claim, damages, liability or action arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in a preliminary Registration Statement or preliminary prospectus if the applicable Initial Purchaser or Participating Broker-Dealer failed to deliver a copy of a final prospectus or an amended or supplemented Registration Statement or prospectus that was made available by the Issuers to such Exchange Offer Indemnified Party prior to the applicable sale to the person or persons asserting the claim which is the basis of indemnification and such final prospectus or amended or supplemented Registration Statement or prospectus cured such defect and (B) this indemnity agreement will be in addition to any liability which the Issuers may otherwise have to such Exchange Offer Indemnified Party. The Issuers will not settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action, suit or proceeding in respect of which indemnification may be sought hereunder (whether or not such Exchange Offer Indemnified Party or any person who controls such Exchange Offer Indemnified Party within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act is a party to such claim, action, suit or proceeding) without the prior written consent of such Exchange Offer Indemnified Party, which consent shall not be unreasonably withheld, unless such settlement, compromise or consent includes an unconditional release of such Exchange Offer Indemnified Party and each such controlling person from all liability arising out of such claim, action, suit or proceeding. No Exchange Offer Indemnified Party will settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action, suit or proceeding in respect of which indemnification may be sought without the prior written consent of the Issuers (which consent will not be unreasonably withheld). (c) Each Holder of the Securities or, if applicable, the Private Exchange Notes, severally and not jointly, will indemnify and hold harmless the Issuers, each director, officer, employee or agent of the Issuers and each person, if any, who controls any Issuer within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and each director, officer, employee or agent of such controlling person from and against any losses, claims, damages or liabilities or any actions in respect thereof, to which any Issuer or any such director, officer, employee, agent or controlling person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in a Registration Statement or prospectus or in any amendment or supplement thereto or in any preliminary prospectus relating to a Shelf Registration, or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to any Issuer by or on behalf of such Holder specifically for inclusion therein; and, subject to the limitation set forth immediately preceding this clause, shall reimburse, as incurred, such indemnified persons for any legal or other expenses reasonably incurred by any Issuer or any such director, officer, employee, agent or controlling person in connection with the investigating or defending or preparing to defend against or appearing as a third-party witness in connection 11 12 with any loss, claim, damage, liability or action in respect thereof. This indemnity agreement will be in addition to any liability which such Holder may otherwise have to any Issuer or any such directors, officers, employees, agents or controlling persons. (d) Promptly after receipt by an indemnified party under this Section 5 of notice of the commencement of any action or proceeding (including a governmental investigation), such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 5, notify the indemnifying party of the commencement thereof; but the omission so to notify the indemnifying party (i) will not relieve it from any liability under paragraph (a), (b) or (c) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights or defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a), (b) or (c) above. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party; provided, however, that if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be one or more legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnifying party shall not have the right to direct the defense of such action on behalf of such indemnified party or parties and such indemnified party or parties shall have the right to select separate counsel to defend such action on behalf of such indemnified party or parties. After notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof and approval by such indemnified party of counsel appointed to defend such action, which approval shall not be unreasonably withheld, the indemnifying party will not be liable to such indemnified party under this Section 5 for any legal or other expenses, other than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof, unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the next preceding sentence (it being understood, however, that in connection with such action the indemnifying party shall not be liable for the expenses of more than one separate counsel (in addition to local counsel) in any one action or separate but substantially similar actions in the same jurisdiction arising out of the same general allegations or circumstances) or (ii) the indemnifying party has authorized the employment of counsel for the indemnified party at the expense of the indemnifying party. (e) In circumstances in which the indemnity agreement provided for in the preceding paragraphs of this Section 5 is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages or liabilities (or actions in respect thereof) (other than by reason of exceptions provided in such Section 5), each indemnifying party, in order to provide for just and equitable contribution, 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 (i) the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party on 12 13 the other from the offering of the Securities or (ii) if the allocation provided by the foregoing clause (i) is not permitted by applicable law, not only such relative benefits but also the relative fault of the indemnifying party or parties on the one hand and the indemnified party on the other in connection with the statements or omissions or alleged statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof). The relative fault of the parties 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 Issuers on the one hand or such Holder or such other indemnified person, as the case may be, on the other, the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission, and any other equitable considerations appropriate in the circumstances. The Issuers and each indemnified party agree that it would not be equitable if the amount of such contribution were determined by pro rata or per capita allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the first sentence of this paragraph (e). Notwithstanding any other provision of this Section 5(e), the Holders of the Securities or, if applicable, the Private Exchange Notes shall not be required to contribute any amount in excess of the amount by which the net proceeds received by such Holders from the sale of the Securities or, if applicable, the Private Exchange Notes pursuant to a Registration Statement exceeds the amount of damages which such Holders have otherwise been required to pay in respect of the same or a similar claim, and 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. For purposes of this paragraph (e), each director, officer, employee and agent of any indemnified party and each person, if any, who controls such indemnified party within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as such indemnified party and each director and officer of any Issuer, and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Issuer. (f) The agreements contained in this Section 5 shall survive the sale of the Securities, the Exchange Notes or, if applicable, the Private Exchange Notes pursuant to a Registration Statement and shall remain in full force and effect, regardless of any termination or cancellation of this Agreement or any investigation made by or on behalf of any indemnified party. 6. Additional Interest Under Certain Circumstances. (a) Additional interest at a rate of 0.5% per annum of the principal amount of the Notes (the "Additional Interest") shall be assessed as follows: (i) if the Exchange Offer Registration Statement is not filed with the Commission by the earlier of (x) 90 days after the Issue Date and (y) the date of filing of a registration statement in respect of an initial public offering of common stock of the Company (other than a registration statement on Form S-8), then, commencing from and including the earlier of such dates, Additional Interest shall be assessed on the Notes; 13 14 (ii) if the Registered Exchange Offer is not completed and a Shelf Registration is not declared effective by the Commission by the Initial Completion Deadline, then, commencing on the Initial Completion Deadline, Additional Interest shall be assessed on the Notes; and (iii) if (A) the Issuers have not exchanged Exchange Notes for all the Securities validly tendered in accordance with the terms of the Registered Exchange Offer on or prior to 30 business days after the date on which the Exchange Offer Registration Statement was declared effective, or (B) if applicable, the Shelf Registration Statement has been declared effective and it ceases to be effective prior to two years (or such later date if such two-year period is extended pursuant to Section 3(j) above or such shorter period as is provided in Section 2(b)) from the Issue Date, then, Additional Interest shall be assessed on the Notes, commencing on (x) the 31st business day after such effective date in the case of (A) above, or (y) the day such Shelf Registration Statement ceases to be effective in the case of (B) above; provided, however, that (l) upon the filing of the Exchange Offer Registration Statement or the Initial Completion Deadline in the case of (i) above, (2) upon completion of the Registered Exchange Offer or the effectiveness of the Shelf Registration Statement in the case of (ii) above, or (3) upon the exchange of Exchange Notes for all the Securities validly tendered in accordance with the terms of the Registered Exchange Offer, or upon the effectiveness of the Shelf Registration Statement which has ceased to remain effective prior to two years (or such later date if extended pursuant to Section 3(j) above or such shorter period as is provided in Section 2(b)) from the date of original issuance of the Securities in the case of (iii) above, Additional Interest on the Notes as a result of such clause (i), (ii) or (iii) shall immediately cease to accrue. (b) Any amount of Additional Interest due pursuant to clauses (i), (ii) or (iii) of Section 6(a) above will be payable in cash semiannually in arrears on each Interest Payment Date (as defined in the Notes), commencing with the first such Interest Payment Date occurring after any such Additional Interest commences to accrue. The amount of Additional Interest will be determined by multiplying the Additional Interest by a fraction, the numerator of which is the number of days such Additional Interest rate was applicable during such period, determined on the basis of a 360-day year comprised of twelve 30-day months, and the denominator of which is 360. (c) If the Issuers effect the Registered Exchange Offer, the Issuers will be entitled to close the Registered Exchange Offer provided that the Issuers have accepted all the Securities theretofore validly tendered in accordance with the terms of the Registered Exchange Offer. 7.
