Brown Incorporated and Credit Suisse First Boston Corporation (each individually, an "Initial Purchaser" and collectively, the "Initial Purchasers"). This Agreement is entered into in connection with the Purchase Agreement, dated as of July 28, 1998, by and among Penhall and the Initial Purchasers (the "Purchase Agreement"), which provides for the sale by Penhall to the Initial Purchasers of $100,000,000 aggregate principal amount of its 12% Senior Notes due 2006 (the "Notes"). In order to induce the Initial Purchasers to enter into the Purchase Agreement, Penhall has agreed to provide the registration rights set forth in this Agreement for the benefit of the Initial Purchasers and any subsequent holder or holders of the Notes. The execution and delivery of this Agreement is a condition to the Initial Purchasers' obligation to purchase the Notes under the Purchase Agreement. The Notes are being sold in connection with a recapitalization (the "Recapitalization") of Penhall Rental Corp. (formerly Penhall International, Inc.), a California corporation ("PRC"). The Recapitalization will be effected through the transactions contemplated by the Agreement and Plan of Merger (the "Merger Agreement") dated July 1, 1998 by and among PRC, the stockholders of PRC, Phoenix Concrete Cutting, Inc., an Arizona corporation ("Phoenix"), Bruckmann, Rosser, Sherrill & Co., L.P. ("BRS") and Penhall. Pursuant to the Merger Agreement, a newly formed, wholly owned subsidiary ("Phoenix Merger Sub") of Phoenix will be merged with and into PRC (the "Reorganization Merger"), with PRC continuing as the surviving corporation. Pursuant to the terms of the Merger Agreement, immediately following the Reorganization Merger and a series of equity transfers contemplated within the Merger Agreement, Phoenix will receive common equity in PRC such that Phoenix will become the corporate parent and will own all the outstanding capital stock of PRC. Immediately following the Reorganization Merger, Penhall will be merged with and into Phoenix (the "Recapitalization Merger" and, together with the Reorganization Merger, the "Mergers"), with Phoenix continuing as the surviving corporation and the successor obligor on the Notes. Following the consummation of the Recapitalization Merger, Phoenix will change its corporate name to "Penhall International Corp." The time of the consummation of the Mergers is referred to herein as the "Effective Time." Immediately after the Effective Time, Phoenix will execute an assumption agreement (the "Assumption Agreement") pursuant to which Phoenix, as survivor of the Recapitalization Merger, will assume all of the obligations of Penhall under this Registration Rights Agreement, and PRC and Penhall Company, a California corporation, will become party to this Registration Rights Agreement as guarantors (the "Guarantors") and unconditionally guarantee the Notes (the "Guarantee") on a senior unsecured basis. As used herein, the "Issuers" shall mean Penhall prior to the Effective Time and, at and as of the Effective Time, Phoenix and the Guarantors. The Notes and the Guarantees are to be issued under an indenture (the "Indenture") to be dated as of August 1, 1998 by and between the Issuers and United States Trust Company of New York, as Trustee (the "Trustee"). Immediately after the Effective Time, Phoenix, the Guarantors and the Trustee will enter into a first supplemental indenture to the Indenture (the "Supplemental Indenture") providing for the express assumption by Phoenix, as survivor of the Merger, of the covenants, agreements and undertakings of Penhall in the Indenture and under the Notes, and the guarantee of the Notes by the Guarantors. References to this Agreement as of and after the Effective Time will refer to this Registration Rights Agreement together with the Assumption Agreement and references to the Indenture as of and after the Effective Time will refer to the Indenture and the Supplemental Indenture.

Exchange Offer (a) To the extent not prohibited by applicable law or applicable interpretation of the staff of the Division of Corporation Finance of the SEC, the Issuers shall file with the SEC, no later than the Filing Date, a Registration Statement (the "Exchange Offer Registration Statement") on an appropriate registration form with respect to a registered offer (the "Exchange Offer") to exchange any and all of the Registrable Notes for a like aggregate principal amount of notes (the "Exchange Notes") of Phoenix, guaranteed by the Guarantors, that are identical in all material respects to the Notes except that the Exchange Notes shall contain no restrictive legend thereon. The Exchange Offer shall comply with all applicable tender offer rules and regulations under the Exchange Act and other applicable laws. The Issuers shall use their reasonable efforts to (x) cause the Exchange Offer Registration Statement to be declared effective under the Securities Act on or before the Effectiveness Date; (y) keep the Exchange Offer open for at least 20 Business Days (or longer if required by applicable law) after the date that notice of the Exchange Offer is mailed to Holders; and (z) consummate the Exchange Offer on or prior to the 180th day after the Issue Date. If, after the Exchange Offer Registration Statement is initially declared effective by the SEC, the Exchange Offer or the issuance of the Exchange Notes thereunder is interfered with by any stop order, injunction or other order or requirement of the SEC or any other governmental agency or court, the Exchange Offer Registration Statement shall be deemed not to have become effective for purposes of this Agreement. Each Holder that participates in the Exchange Offer will be required to represent to the Issuers in writing that any Exchange Notes to be received by it will be acquired in the ordinary course of its business, that at the time of the consummation of the Exchange Offer such Holder will have no arrangement or understanding with any Person to participate in the distribution of the Exchange Notes in violation of the pro- 6 visions of the Securities Act, and that such Holder is not an affiliate of the Issuers within the meaning of the Securities Act or, if such Holder is such an affiliate, that it will comply with the registration and prospectus delivery requirements of the Securities Act applicable to it, that if such Holder is a broker-dealer, it is not engaged in, and does not intend to engage in, a distribution of Exchange Notes, and that if such Holder is a broker-dealer that will receive Exchange Notes for its own account in exchange for Notes that were acquired as a result of market-making or other trading activities, it will deliver a prospectus in connection with any resale of such Exchange Notes. Upon consummation of the Exchange Offer in accordance with this Section 2, the provisions of this Agreement shall continue to apply, solely with respect to Registrable Notes that are Private Exchange Notes, Exchange Notes as to which Section 2(c)(iv) is applicable and Exchange Notes held by Participating Broker-Dealers, and the Issuers shall have no further obligation to register Registrable Notes (other than Private Exchange Notes and other than in respect of any Exchange Notes as to which clause 2(c)(iv) hereof applies) pursuant to Section 3 hereof. No securities other than the Exchange Notes shall be included in the Exchange Offer Registration Statement. (b) The Issuers shall include within the Prospectus contained in the Exchange Offer Registration Statement a section entitled "Plan of Distribution," reasonably acceptable to the Holders, which shall contain a summary statement of the positions taken or policies made by the staff of the SEC with respect to the potential "underwriter" status of any broker-dealer that is the beneficial owner (as defined in Rule 13d-3 under the Exchange Act) of Exchange Notes received by such broker-dealer in the Exchange Offer or any other Person with similar prospectus delivery requirements for use in connection with any resale of Exchange Notes (a "Participating Broker-Dealer"), whether such positions or policies have been publicly disseminated by the staff of the SEC or such positions or policies represent the prevailing views of the staff of the SEC. Such "Plan of Distribution" section shall also expressly permit, to the extent permitted by applicable policies and regulations of the SEC, the use of the Prospectus by all Persons subject to the prospectus delivery requirements of the Securities Act, including, to the extent permitted by applicable policies and regulations of the SEC, all Participating Broker-Dealers, and include a statement describing the means by which Participating Broker-Dealers may resell the Exchange Notes in compliance with the Securities Act. 7 The Issuers shall use their reasonable 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 is necessary to comply with applicable law in connection with any resale of the Exchange Notes covered thereby; provided, however, that such period shall not exceed 180 days after such Exchange Offer Registration Statement is declared effective (or such longer period if extended pursuant to the last paragraph of Section 5 hereof), or such earlier date as each Participating Broker-Dealer shall have notified the Company in writing that such Participating Broker-Dealer has resold all Exchange Notes acquired in the Exchange Offer (the "Applicable Period"). If, prior to consummation of the Exchange Offer, any Initial Purchaser holds any Notes acquired by it that have, or that are reasonably likely to be determined to have, the status of an unsold allotment in an initial distribution, or if any Holder is not entitled to participate in the Exchange Offer, the Issuers upon the request of any such Holder shall simultaneously with the delivery of the Exchange Notes in the Exchange Offer, issue and deliver to any such Holder, in exchange (the "Private Exchange") for such Notes held by any such Holder, a like principal amount of notes (the "Private Exchange Notes") of Phoenix, guaranteed by the Guarantors, that are identical in all material respects to the Exchange Notes (except that they may bear a customary legend with respect to restrictions on transfer). The Private Exchange Notes shall be issued pursuant to the same indenture as the Exchange Notes and bear the same CUSIP number as the Exchange Notes. Interest on the Exchange Notes and the Private Exchange Notes will accrue from (A) the later of (i) the last interest payment date on which interest was paid on the Notes surrendered in exchange therefor or (ii) if the Notes are surrendered for exchange on a date subsequent to the record date for an interest payment date to occur on or after the date of such exchange and as to which interest will be paid, the date of such interest payment or (B) if no interest has been paid on the Notes, from the date of the original issuance of the Notes. In connection with the Exchange Offer, the Issuers shall: (1) mail, or cause to be mailed, to each Holder entitled to participate in the Exchange Offer a copy of the Prospectus forming part of the Exchange Offer Registration 8 Statement, together with an appropriate letter of transmittal and related documents; (2) keep the Exchange Offer open for not less than 20 Business Days after the date that notice of the Exchange Offer is mailed to Holders (or longer if required by applicable law); (3) utilize the services of a depositary for the Exchange Offer with an address in the Borough of Manhattan, The City of New York; (4) permit Holders to withdraw tendered Notes at any time prior to the close of business, New York time, on the last Business Day on which the Exchange Offer shall remain open; provided, however, that withdrawal rights may be terminated upon any extension of the Exchange Offer; and (5) otherwise comply in all material respects with all applicable laws, rules and regulations. As soon as practicable after the close of the Exchange Offer and the Private Exchange, if any, the Issuers shall: (1) accept for exchange all Notes validly tendered and not validly withdrawn pursuant to the Exchange Offer and the Private Exchange, if any; (2) deliver to the Trustee for cancellation all Notes so accepted for exchange; and (3) cause the Trustee to authenticate and deliver promptly to each Holder of Notes, Exchange Notes or Private Exchange Notes, as the case may be, equal in principal amount to the Notes of such Holder so accepted for exchange. The Exchange Offer and the Private Exchange shall not be subject to any conditions, other than that (i) the Exchange Offer or Private Exchange, as the case may be, does not violate applicable law or any applicable interpretation of the staff of the SEC, (ii) no action or proceeding shall have been instituted or threatened in any court or by any governmental agency which might materially impair the ability of the Issuers to proceed with the Exchange Offer or the Private Exchange, and no material adverse development shall have occurred in any existing action or proceeding with respect to the Issuers, and (iii) all governmental approvals shall have been obtained, 9 which approvals the Issuers deem necessary for the consummation of the Exchange Offer or Private Exchange. The Exchange Notes and the Private Exchange Notes shall be issued under (i) the Indenture or (ii) an indenture identical in all material respects to the Indenture and which, in either case, has been qualified under the TIA or is exempt from such qualification and shall provide that the Exchange Notes shall not be subject to the transfer restrictions set forth in the Indenture. The Indenture or such indenture shall provide that the Exchange Notes, the Private Exchange Notes and the Notes shall vote and consent together on all matters as one class and that none of the Exchange Notes, the Private Exchange Notes or the Notes will have the right to vote or consent as a separate class on any matter. (c) If (i) because of any change in law or in currently prevailing interpretations of the staff of the SEC, the Issuers are not permitted to effect the Exchange Offer, (ii) the Exchange Offer is not consummated within 180 days of the Issue Date, (iii) the Initial Purchasers or any holder of Private Exchange Notes so requests in writing to the Issuers at any time after the consummation of the Exchange Offer with respect to Private Exchange Notes that are not eligible for resale without restriction under federal securities laws, or (iv) in the case of any Holder that participates in the Exchange Offer, such Holder does not receive Exchange Notes on the date of the exchange that may be sold without restriction under federal securities laws (other than due solely to the status of such Holder as an affiliate of any of the Issuers within the meaning of the Securities Act) and so notifies the Issuers within 30 days after such Holder first becomes aware of such restrictions, in the case of each of clauses (i) to and including (iv) of this sentence, then the Issuers shall promptly deliver to the Holders and the Trustee written notice thereof (the "Shelf Notice") and shall file a Shelf Registration pursuant to Section 3 hereof. 3. Shelf Registration If at any time a Shelf Notice is delivered as contemplated by Section 2(c) hereof, then: (a) Shelf Registration. The Issuers shall file with the SEC a Registration Statement for an offering to be made on a continuous basis pursuant to Rule 415 covering all of the Registrable Notes not permitted to be exchanged in the Exchange Offer in accordance with the terms of this Agreement, Private Exchange Notes and Exchange Notes as to which Section 2(c)(iv) 10 is applicable (the "Initial Shelf Registration"). The Issuers shall use their reasonable efforts to file with the SEC the Initial Shelf Registration on or before the applicable Filing Date. The Initial Shelf Registration shall be on Form S-1 or another appropriate form permitting registration of such Registrable Notes for resale by Holders in the reasonable manner or manners designated by them (including, without limitation, one or more underwritten offerings). The Issuers shall not permit any securities other than the Registrable Notes to be included in the Initial Shelf Registration or any Subsequent Shelf Registration (as defined below). The Issuers shall use their reasonable efforts to cause the Initial Shelf Registration to be declared effective under the Securities Act on or prior to the Effectiveness Date and to keep the Initial Shelf Registration continuously effective under the Securities Act until the date which is two years from the Issue Date, subject to extension pursuant to the last paragraph of Section 5 hereof (the "Effectiveness Period"), or such shorter period ending when all Registrable Notes covered by the Shelf Registration have been sold in the manner set forth and as contemplated in the Initial Shelf Registration or, if applicable, a Subsequent Shelf Registration covering all of the Registrable Notes covered by and not sold under the Initial Shelf Registration Statement or an earlier Subsequent Shelf Registration has been declared effective under the Securities Act; provided, however, that the Effectiveness Period in respect of the Initial Shelf Registration shall be extended to the extent required to permit dealers to comply with the applicable prospectus delivery requirements of Rule 174 under the Securities Act and as otherwise provided herein and shall be reduced to the extent that the applicable provisions of Rule 144(k) are amended or revised to reduce the two year holding period set forth therein or any similar rule providing for a shorter holding period; provided, further, that the Issuers may suspend the availability or effectiveness of a Shelf Registration Statement by written notice to the Holders for a period not to exceed 40 calendar days in any consecutive 365-day period if (i) an event occurs and is continuing as a result of which such Shelf Registration Statement would, in the Issuers' good faith judgment, contain an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading and (ii) (a) the Issuers determine in good faith that the disclosure of such event at such time would have a material adverse effect on the business, operations or prospects of the Issuers, taken as a whole, or (b) the disclosure otherwise relates to a previously undisclosed pending material business transaction, the disclosure of which would impede the Issuers' ability to consummate such 11 transaction; provided, further, however, that if at the end of the Effectiveness Period, all of the Registrable Notes covered by the Shelf Registration Statement have not been sold, the Issuers will cause the effectiveness to be extended by the number of days during which the Shelf Registration Statement was not usable pursuant to the preceding proviso. No Holder of Registrable Notes may include any of its Registrable Notes in any Shelf Registration Statement pursuant to this Agreement unless and until (i) such Holder (other than an Initial Purchaser) agrees in writing to be bound by all of the provisions of this Agreement applicable to such Holder, and (ii) such Holder furnishes to the Issuers in writing, within 15 Business Days after receipt of a request therefor, such information as the Issuers may reasonably request for use in connection with any Shelf Registration Statement or Prospectus or preliminary prospectus included therein. No Holder of Registrable Notes shall be entitled to Additional Interest pursuant to Section 4 hereof unless and until such Holder shall have provided all such reasonably requested information. Each Holder of Registrable Notes as to which any Shelf Registration Statement is being effected agrees to furnish promptly to the Issuers all information required to be disclosed in order to make information previously furnished to the Issuers by such Holder not a material misstatement or omission. (b) Subsequent Shelf Registrations. If the Initial Shelf Registration or any Subsequent Shelf Registration ceases to be effective for any reason at any time during the Effectiveness Period (other than because of the sale of all of the securities registered thereunder), the Issuers shall use their reasonable efforts to obtain the prompt withdrawal of any order suspending the effectiveness thereof, and in any event shall as soon as practicable after such cessation of effectiveness amend the Initial Shelf Registration in a manner to obtain the withdrawal of the order suspending the effectiveness thereof, or file an additional Shelf Registration Statement pursuant to Rule 415 covering all of the Registrable Notes covered by and not sold under the Initial Shelf Registration or an earlier Subsequent Shelf Registration (each, a "Subsequent Shelf Registration"). If a Subsequent Shelf Registration is filed, the Issuers shall use their reasonable efforts to cause the Subsequent Shelf Registration to be declared effective under the Securities Act as soon as practicable after such filing and to keep such Shelf Registration continuously effective for a period equal to the number of days in the Effectiveness Period (subject to reduction as provided herein) less the aggregate number of days during which the Initial Shelf Registration or 12 any Subsequent Shelf Registration was previously continuously effective. As used herein the term "Shelf Registration" means the Initial Shelf Registration and any Subsequent Shelf Registration. (c) Supplements and Amendments. The Issuers shall promptly supplement and amend any Shelf Registration if required by the rules, regulations or instructions applicable to the registration form used for such Shelf Registration, if required by the Securities Act, or if reasonably requested by the Holders of a majority in aggregate principal amount of the Registrable Notes covered by such Registration Statement or by any underwriter of such Registrable Notes. 4. Additional Interest (a) The Issuers and the Initial Purchasers agree that the Holders will suffer damages if the Issuers fail to fulfill their obligations under Section 2 or Section 3 hereof and that it would not be feasible to ascertain the extent of such damages with precision. Accordingly, the Issuers agree to pay, as liquidated damages, additional interest on the Notes ("Additional Interest") under the circumstances and to the extent set forth below (each of which shall be given independent effect): (i) if (A) neither the Exchange Offer Registration Statement nor the Initial Shelf Registration has been filed on or prior to the applicable Filing Date or (B) notwithstanding that the Issuers have consummated or will consummate the Exchange Offer, the Issuers are required to file a Shelf Registration and such Shelf Registration is not filed on or prior to the Filing Date applicable thereto, then, commencing on the day after any such Filing Date, Additional Interest shall accrue on the principal amount of the Notes at a rate of 0.5% per annum for the first 90 days immediately following such applicable Filing Date, and such Additional Interest rate shall increase by an additional 0.5% per annum at the beginning of each subsequent 90-day period; or (ii) if (A) neither the Exchange Offer Registration Statement nor the Initial Shelf Registration is declared effective by the SEC on or prior to the Effectiveness Date applicable thereto or (B) notwithstanding that the Issuers have consummated or will consummate the Exchange Offer, the Issuers are required to file a Shelf Registration and such Shelf Registration is not declared effective by the SEC on or prior to the Effectiveness Date applicable to 13 such Shelf Registration, then, commencing on the day after such Effectiveness Date, Additional Interest shall accrue on the principal amount of the Notes at a rate of 0.5% per annum for the first 90 days immediately following the day after such Effectiveness Date, and such Additional Interest rate shall increase by an additional 0.5% per annum at the beginning of each subsequent 90-day period; or (iii) if (A) the Issuers have not exchanged Exchange Notes for all Notes validly tendered in accordance with the terms of the Exchange Offer on or prior to the 30th day after the Exchange Offer Registration Statement is declared effective or (B) if applicable, a Shelf Registration has been declared effective and such Shelf Registration ceases to be effective at any time during the Effectiveness Period for a period of ten consecutive days without being succeeded by an effective Shelf Registration Statement, then Additional Interest shall accrue on the principal amount of the Notes at a rate of 0.5% per annum for the first 90 days commencing on the (x) 31st day after the Exchange Offer Registration Statement is declared effective, in the case of (A) above, or (y) the 11th day after such Shelf Registration ceases to be effective, in the case of (B) above, and such Additional Interest rate shall increase by an additional 0.5% per annum at the beginning of each such subsequent 90-day period; provided, however, that the Additional Interest rate on the Notes may not exceed at any one time in the aggregate 2.0% per annum; provided, further, however, that (1) upon the filing of the applicable Exchange Offer Registration Statement or the applicable Shelf Registration as required hereunder (in the case of clause (i) above of this Section 4), (2) upon the effectiveness of the Exchange Offer Registration Statement or the applicable Shelf Registration Statement as required hereunder (in the case of clause (ii) of this Section 4), or (3) upon the exchange of the Exchange Notes for all Notes tendered (in the case of clause (iii)(A) of this Section 4), or upon the effectiveness of the applicable Shelf Registration Statement which had ceased to remain effective (in the case of (iii)(B) of this Section 4), Additional Interest on the Notes in respect of which such events relate as a result of such clause (or the relevant subclause thereof), as the case may be, shall cease to accrue. Additional Interest will not accrue with respect to a Shelf Registration Statement during any period in which the Issuers suspend the effectiveness or use of such Shelf Registration Statement in accordance with the terms of Section 3(a) hereof. 14 (b) The Issuers shall notify the Trustee within one Business Day after each and every date on which an event occurs in respect of which Additional Interest is required to be paid (an "Event Date"). Any amounts of Additional Interest due pursuant to (a)(i), (a)(ii) or (a)(iii) of this Section 4 will be payable in cash semi-annually on the interest payment dates specified in the Indenture and the Notes to the holders of record as specified in the Indenture, 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 applicable Additional Interest rate by the principal amount of the Registrable Notes, multiplied 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 composed of twelve 30-day months and, in the case of a partial month, the actual number of days elapsed), and the denominator of which is 360. 5. Registration Procedures In connection with the filing of any Registration Statement pursuant to Sections 2 or 3 hereof, the Issuers shall effect such registrations to permit the sale of the securities covered thereby in accordance with the intended method or methods of disposition thereof, and pursuant thereto and in connection with any Registration Statement filed by the Issuers hereunder the Issuers shall: (a) Prepare and file with the SEC prior to the applicable Filing Date, a Registration Statement or Registration Statements as prescribed by Sections 2 or 3 hereof, and use its reasonable efforts to cause each such Registration Statement to become effective and remain effective as provided herein; provided, however, that, if (1) such filing is pursuant to Section 3 hereof or (2) a Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during the Applicable Period relating thereto, before filing any Registration Statement or Prospectus or any amendments or supplements thereto, the Issuers shall furnish to and afford the Holders of the Registrable Notes covered by such Registration Statement or BT Alex. Brown Incorporated (the "Representative") on behalf of such Participating Broker-Dealer, as the case may be, their or its counsel and the managing underwriters, if any, a reasonable opportunity to review copies of all such documents (including 15 copies of any documents to be incorporated by reference therein and all exhibits thereto) proposed to be filed (in each case at least five business days prior to such filing, or such later date as is reasonable under the circumstances). The Issuers shall not file any Registration Statement or Prospectus or any amendments or supplements thereto if the Holders of a majority in aggregate principal amount of the Registrable Notes covered by such Registration Statement, their counsel, or the managing underwriters, if any, shall reasonably object. (b) Prepare and file with the SEC such amendments and post-effective amendments to each Shelf Registration Statement or Exchange Offer Registration Statement, as the case may be, as may be necessary to keep such Registration Statement continuously effective for the Effectiveness Period or the Applicable Period or until consummation of the Exchange Offer, as the case may be; cause the related Prospectus to be supplemented by any Prospectus supplement required by applicable law, and as so supplemented to be filed pursuant to Rule 424 (or any similar provisions then in force) promulgated under the Securities Act; and comply with the provisions of the Securities Act and the Exchange Act applicable to it with respect to the disposition of all securities covered by such Registration Statement as so amended or in such Prospectus as so supplemented and with respect to the subsequent resale of any securities being sold by a Participating Broker-Dealer covered by any such Prospectus. The Issuers shall be deemed not to have used their reasonable efforts to keep a Registration Statement effective during the Effective Period or the Applicable Period, as the case may be, relating thereto if the Issuers voluntarily take any action that would result in selling Holders of the Registrable Notes covered thereby or Participating Broker-Dealers seeking to sell Exchange Notes not being able to sell such Registrable Notes or such Exchange Notes during that period unless (i) such action is required by applicable law or (ii) the Issuers comply with this Agreement, including without limitation, the provisions of Section 5(k) or the last paragraph of this Section 5. (c) If (1) a Shelf Registration is filed pursuant to Section 3 hereof, or (2) a Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during the Applicable Period relating thereto from whom the Issuers have received written notice 16 that it will be a Participating Broker-Dealer in the Exchange Offer, notify the selling Holders of Registrable Notes, or the Representative on behalf of such Participating Broker-Dealer, as the case may be, their or its counsel and the managing underwriters, if any, promptly (but in any event within two Business Days), and, if requested by any such Person, confirm such notice in writing, (i) when a Prospectus or any Prospectus supplement or post-effective amendment has been filed, and, with respect to a Registration Statement or any post-effective amendment, when the same has become effective under the Securities Act (including in such notice a written statement that any Holder may, upon request, obtain, at the sole expense of the Issuers, one conformed copy of such Registration Statement or post-effective amendment including financial statements and schedules, documents incorporated or deemed to be incorporated by reference therein and exhibits), (ii) of the issuance by the SEC of any stop order suspending the effectiveness of a Registration Statement or of any order preventing or suspending the use of any preliminary prospectus or the initiation of any proceedings for that purpose, (iii) if at any time when a prospectus is required by the Securities Act to be delivered in connection with sales of the Registrable Notes or resales of Exchange Notes by Participating Broker-Dealers the representations and warranties of the Issuers contained in any agreement (including any underwriting agreement) contemplated by Section 5(m) hereof cease to be true and correct in all material respects, (iv) of the receipt by the Issuers of any notification with respect to the suspension of the qualification or exemption from qualification of a Registration Statement or any of the Registrable Notes or the Exchange Notes to be sold by any Participating Broker-Dealer for offer or sale in any jurisdiction, or the initiation or threatening of any proceeding for such purpose, (v) of the happening of any event, the existence of any condition or any information becoming known to the Issuers that makes any statement made in such Registration Statement or related Prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires the making of any changes in or amendments or supplements to such Registration Statement, Prospectus or documents so that, in the case of the Registration Statement, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and that in the case of the Prospectus, it will not contain any untrue statement of a material fact 17 or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and (vi) of the Issuers' determination that a post-effective amendment to a Registration Statement would be appropriate. (d) If (1) a Shelf Registration is filed pursuant to Section 3 hereof, or (2) a Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during the Applicable Period, use its reasonable efforts to prevent the issuance of any order suspending the effectiveness of a Registration Statement or of any order preventing or suspending the use of a Prospectus or suspending the qualification (or exemption from qualification) of any of the Registrable Notes or the Exchange Notes to be sold by any Participating Broker-Dealer, for sale in any jurisdiction, and, if any such order is issued, to use its reasonable efforts to obtain the withdrawal of any such order at the earliest possible date.

(f) If (1) a Shelf Registration is filed pursuant to Section 3 hereof, or (2) a Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Secu- 18 rities Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during the Applicable Period, furnish to each selling Holder of Registrable Notes and the Representative on behalf of such Participating Broker-Dealer and to counsel and each managing underwriter, if any, at the sole expense of the Issuers, one conformed copy of the Registration Statement or Registration Statements and each post-effective amendment thereto, including financial statements and schedules, and, if requested, all documents incorporated or deemed to be incorporated therein by reference and all exhibits. (g) If (1) a Shelf Registration is filed pursuant to Section 3 hereof, or (2) a Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during the Applicable Period, deliver to each selling Holder of Registrable Notes, or each such Participating Broker-Dealer, as the case may be, their respective counsel, and the underwriters, if any, at the sole expense of the Issuers, as many copies of the Prospectus or Prospectuses (including each form of preliminary prospectus) and each amendment or supplement thereto and any documents incorporated by reference therein as such Persons may reasonably request; and, subject to the last paragraph of this Section 5, the Issuers hereby consent to the use of such Prospectus and each amendment or supplement thereto by each of the selling Holders of Registrable Notes or each such Participating Broker-Dealer, as the case may be, and the underwriters or agents, if any, and dealers (if any), in connection with the offering and sale of the Registrable Notes covered by, or the sale by Participating Broker-Dealers of the Exchange Notes pursuant to, such Prospectus and any amendment or supplement thereto.

(i) If a Shelf Registration is filed pursuant to Section 3 hereof, cooperate with the selling Holders of Registrable Notes and the managing underwriter or underwriters, if any, to facilitate the timely preparation and delivery of certificates representing Registrable Notes to be sold, which certificates shall not bear any restrictive legends and shall be in a form eligible for deposit with The Depository Trust Company; and enable such Registrable Notes to be in such denominations and registered in such names as the managing underwriter or underwriters, if any, or Holders may reasonably request at least two Business Days prior to any sale of such Registrable Notes.

The above shall be done at each closing under such underwriting agreement, or as and to the extent required thereunder. (n) If (1) a Shelf Registration is filed pursuant to Section 3 hereof, or (2) a Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during the Applicable Period, make available for inspection by any selling Holder of such Registrable Notes being sold, or each such Participating Broker-Dealer, as the case may be, any underwriter par- 22 ticipating in any such disposition of Registrable Notes, if any, and any attorney, accountant or other agent retained by any such selling Holder or each such Participating Broker-Dealer, as the case may be, or underwriter (collectively, the "Inspectors"), at the offices where normally kept, during reasonable business hours, all financial and other records, pertinent corporate documents and instruments of the Issuers and their subsidiaries (collectively, the "Records") as shall be reasonably necessary to enable them to exercise any applicable due diligence responsibilities, and cause the officers, directors and employees of the Issuers and their subsidiaries to supply all information reasonably requested by any such Inspector in connection with such Registration Statement and Prospectus. Each Inspector shall agree in writing that it will keep the Records confidential and that it will not disclose any of the Records unless (i) the disclosure of such Records is necessary to avoid or correct a misstatement or omission in such Registration Statement or Prospectus, (ii) the release of such Records is ordered pursuant to a subpoena or other order from a court of competent jurisdiction, or (iii) the information in such Records has been made generally available to the public; provided, however, that such Inspector shall take such actions as are reasonably necessary to protect the confidentiality of such information (if practicable) to the extent such action is otherwise not inconsistent with, an impairment of or a derogation of the rights and interests of the Holder or any Inspector. Each selling Holder of such Registrable Notes and each such Participating Broker-Dealer will be required to agree that information obtained by it as a result of such inspections shall be deemed confidential and shall not be used by it as the basis for any market transactions in the securities of the Issuers unless and until such information is made generally available to the public. Each selling Holder of such Registrable Notes and each such Participating Broker-Dealer will be required to further agree that it will, upon learning that disclosure of such Records is sought in a court of competent jurisdiction, give notice to the Issuers and allow the Issuers to undertake appropriate action to prevent disclosure of the Records deemed confidential at the Issuers' expense. (o) Provide an indenture trustee for the Registrable Notes or the Exchange Notes, as the case may be, and cause the Indenture or the trust indenture provided for in Section 2(a) hereof, as the case may be, to be qualified under the TIA not later than the effective date of the first 23 Registration Statement relating to the Registrable Notes; and in connection therewith, cooperate with the trustee under any such indenture and the Holders of the Registrable Notes, to effect such changes to such indenture as may be required for such indenture to be so qualified in accordance with the terms of the TIA; and execute, and use its reasonable efforts to cause such trustee to execute, all documents as may be required to effect such changes, and all other forms and documents required to be filed with the SEC to enable such indenture to be so qualified in a timely manner. (p) Comply with all applicable rules and regulations of the SEC and make generally available to their respective securityholders earnings statements satisfying the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any similar rule promulgated under the Securities Act) no later than 45 days after the end of any 12-month period (or 90 days after the end of any 12-month period if such period is a fiscal year) (i) commencing at the end of any fiscal quarter in which Registrable Notes are sold to underwriters in a firm commitment or best efforts underwritten offering and (ii) if not sold to underwriters in such an offering, commencing on the first day of the first fiscal quarter of the Issuers after the effective date of a Registration Statement, which statements shall cover said 12-month periods. (q) If the Exchange Offer or a Private Exchange is to be consummated, upon delivery of the Registrable Notes by Holders to the Issuers (or to such other Person as directed by the Issuers) in exchange for the Exchange Notes or the Private Exchange Notes, as the case may be, the Issuers shall mark, or cause to be marked, on such Registrable Notes that such Registrable Notes are being cancelled in exchange for the Exchange Notes or the Private Exchange Notes, as the case may be; in no event shall such Registrable Notes be marked as paid or otherwise satisfied. (r) Use its reasonable efforts to cause the Registrable Notes covered by a Registration Statement to be rated with the appropriate rating agencies, if so requested by the managing underwriter or underwriters, if any. (s) Cooperate with the managing underwriter, if any, participating in the disposition of Registrable Notes and its counsel in connection with any filings required to be 24 made with the National Association of Securities Dealers, Inc. (the "NASD"). (t) Use its reasonable efforts to take all other steps reasonably necessary to effect the registration of the Exchange Notes and/or Registrable Notes covered by a Registration Statement contemplated hereby. The Issuers may require each seller of Registrable Notes as to which any registration is being effected to furnish to the Issuers such information regarding such seller and the distribution of such Registrable Notes as the Issuers may, from time to time, reasonably request. The Issuers may exclude from such registration the Registrable Notes of any seller so long as such seller fails to furnish such information within a reasonable time after receiving such request. Each seller as to which any Shelf Registration is being effected agrees to furnish promptly to the Issuers all information required to be disclosed in order to make the information previously furnished to the Issuers by such seller not to contain a material misstatement or omission. Each Holder of Registrable Notes and each Participating Broker-Dealer agrees by its acquisition of such Registrable Notes or Exchange Notes to be sold by such Participating Broker-Dealer, as the case may be, that, upon actual receipt of any notice from the Issuers of the happening of any event of the kind described in Section 5(c)(ii), 5(c)(iv), 5(c)(v), or 5(c)(vi) hereof, such Holder will forthwith discontinue disposition of such Registrable Notes covered by such Registration Statement or Prospectus or Exchange Notes to be sold by such Holder or Participating Broker-Dealer, as the case may be, and the dissemination of the applicable Prospectus until such Holder's or Participating Broker-Dealer's receipt of the copies of the supplemented or amended Prospectus contemplated by Section 5(k) hereof, or until it is advised in writing (the "Advice") by the Issuers that the use of the applicable Prospectus may be resumed. In the event that the Issuers shall give any such notice, each of the Effectiveness Period and the Applicable Period shall be extended by the number of days during such periods from and including the date of the giving of such notice to and including the date when each seller of Registrable Notes covered by such Registration Statement or Exchange Notes to be sold by such Participating Broker-Dealer, as the case may be, shall have received (x) the copies of the supplemented or amended Prospectus contemplated by Section 5(k) hereof or (y) the Advice. 25 6. Registration Expenses All fees and expenses incident to the performance of or compliance with this Agreement by the Issuers shall be borne by the Issuers whether or not the Exchange Offer Registration Statement or any Shelf Registration Statement is filed or becomes effective or the Exchange Offer is consummated, including, without limitation, (i) all registration and filing fees (including, without limitation, (A) fees with respect to filings required to be made with the NASD in connection with an underwritten offering and (B) fees and expenses of compliance with state securities or Blue Sky laws (including, without limitation, reasonable fees and disbursements of counsel in connection with Blue Sky qualifications of the Registrable Notes or Exchange Notes and determination of the eligibility of the Registrable Notes or Exchange Notes for investment under the laws of such jurisdictions (x) where the holders of Registrable Notes are located, in the case of the Exchange Notes, or (y) as provided in Section 5(h) hereof, in the case of Registrable Notes or Exchange Notes to be sold by a Participating Broker-Dealer during the Applicable Period)), (ii) printing expenses, including, without limitation, expenses of printing certificates for Registrable Notes or Exchange Notes in a form eligible for deposit with The Depository Trust Company and of printing prospectuses if the printing of prospectuses is requested by the managing underwriter or underwriters, if any, by the Holders of a majority in aggregate principal amount of the Registrable Notes included in any Registration Statement or in respect of Exchange Notes to be sold by any Participating Broker-Dealer during the Applicable Period, as the case may be, (iii) messenger, telephone and delivery expenses, (iv) fees and disbursements of counsel for the Issuers and, in the case of a Shelf Registration, reasonable fees and disbursements of one special counsel for all of the sellers of Registrable Notes (exclusive of any counsel retained pursuant to Section 7 hereof), (v) fees and disbursements of all independent certified public accountants referred to in Section 5(m)(iii) hereof (including, without limitation, the expenses of any special audit and "cold comfort" letters required by or incident to such performance), (vi) Securities Act liability insurance, if the Issuers desire such insurance, (vii) fees and expenses of all other Persons retained by the Issuers, (viii) internal expenses of the Issuers (including, without limitation, all salaries and expenses of officers and employees of the Issuers performing legal or accounting duties), (ix) the expense of any annual audit, (x) the fees and expenses incurred in connection with the listing of the securities to be registered on any securities exchange, and the obtaining of a rating of the securities, in each case, if applicable, and (xi) the expenses relat- 26 ing to printing, word processing and distributing all Registration Statements, underwriting agreements, indentures and any other documents necessary in order to comply with this Agreement. Notwithstanding the foregoing, each Holder shall pay any underwriting discounts and commissions incurred in connection with Registrable Notes sold on such Holder's behalf. 7. Indemnification (a) Each of the Issuers, jointly and severally, agree to indemnify and hold harmless each Holder of Registrable Notes and each Participating Broker-Dealer selling Exchange Notes during the Applicable Period, the officers and directors of each such Person, and each Person, if any, who controls any such Person within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act (each, a "Participant"), from and against any and all losses, claims, damages, judgments, liabilities and expenses (including, without limitation, the reasonable legal fees and other expenses actually incurred in connection with any suit, action or proceeding or any claim asserted) caused by, arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement (or any amendment thereto) or Prospectus (as amended or supplemented if the Issuers shall have furnished any amendments or supplements thereto) or any preliminary prospectus, or caused by, arising out of or based upon any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the case of the Prospectus in the light of the circumstances under which they were made, not misleading, except insofar as such losses, claims, damages, liabilities or expenses are caused by, arise out of or are based upon any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with information relating to any Participant furnished to the Issuers in writing by such Participant expressly for use therein; provided, however, that the Issuers will not be liable if such untrue statement or omission or alleged untrue statement or omission was contained or made in any preliminary prospectus and corrected in the final Prospectus or any amendment or supplement thereto and any such loss, liability, claim, or damage or expense suffered or incurred by the Participants resulted from any action, claim or suit by any Person who purchased Registrable Notes or Exchange Notes which are the subject thereof from such Participant and such Participant failed to deliver or provide a copy of the final Prospectus (as amended or supplemented) to such Person with or prior to the confirmation of the sale of such Registrable Notes or Exchange Notes sold to such Person if required by applicable law, unless such failure to 27 deliver or provide a copy of the final Prospectus (as amended or supplemented) was a result of material noncompliance by the Issuers with Section 5 of this Agreement. (b) Each Participant agrees, severally and not jointly, to indemnify and hold harmless the Issuers, their respective directors, their respective officers who sign the Registration Statement and each Person who controls the Issuers within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Issuers to each Participant, but only with reference to information relating to such Participant furnished to the Issuers in writing by such Participant expressly for use in any Registration Statement or Prospectus, any amendment or supplement thereto, or any preliminary prospectus. The liability of any Participant under this paragraph shall in no event exceed the proceeds received by such Participant from sales of Registrable Notes or Exchange Notes giving rise to such obligations. (c) If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any Person in respect of which indemnity may be sought pursuant to either of the two preceding paragraphs, such Person (the "Indemnified Person") shall promptly notify the Persons against whom such indemnity may be sought (the "Indemnifying Persons") in writing, and the Indemnifying Persons shall be entitled to, and upon request of the Indemnified Person shall, retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others the Indemnifying Persons may reasonably designate in such proceeding and shall pay the reasonable fees and expenses actually incurred by such counsel related to such proceeding; provided, however, that the failure to so notify the Indemnifying Persons shall not relieve any of them of any obligation or liability which any of them may have hereunder or otherwise except to the extent it is materially prejudiced by such failure. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Persons and the Indemnified Person shall have mutually agreed to the contrary, (ii) the Indemnifying Persons shall have failed within a reasonable period of time to retain counsel reasonably satisfactory to the Indemnified Person or (iii) the named parties in any such proceeding (including any impleaded parties) include both any Indemnifying Person and the Indemnified Person or any affiliate thereof and representation of both parties by the same counsel would be inappropriate due to actual or potential 28 conflicting interests between them. It is understood that, unless there exists a conflict among Indemnified Persons, the Indemnifying Persons shall not, in connection with such proceeding or separate but substantially similar related proceeding in the same jurisdiction arising out of the same general allegations, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed promptly as they are incurred. Any such separate firm for the Participants and such control Persons of Participants shall be designated in writing by Participants who sold a majority in interest of Registrable Notes and Exchange Notes sold by all such Participants and shall be reasonably acceptable to the Issuers and any such separate firm for the Issuers, their respective directors, their respective officers and such control Persons of the Issuers shall be designated in writing by the Issuers and shall be reasonably acceptable to the Holders. The Indemnifying Persons shall not be liable for any settlement of any proceeding effected without its prior written consent (which consent shall not be unreasonably withheld or delayed), but if settled with such consent or if there be a final non-appealable judgment for the plaintiff for which the Indemnified Person is entitled to indemnification pursuant to this Agreement, each of the Indemnifying Persons agrees to indemnify and hold harmless each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. No Indemnifying Person shall, without the prior written consent of the Indemnified Persons (which consent shall not be unreasonably withheld or delayed), effect any settlement or compromise of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party, or indemnity could have been sought hereunder by such Indemnified Person, unless such settlement (A) includes an unconditional written release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (B) does not include any statement as to an admission of fault, culpability or failure to act by or on behalf of such Indemnified Person. (d) If the indemnification provided for in clauses (a) and (b) of this Section 7 is for any reason unavailable to, or insufficient to hold harmless, an Indemnified Person in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each Indemnifying Person under such paragraphs, in lieu of indemnifying such Indemnified Person thereunder and in order to provide for just and equitable contribution, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, 29 damages, liabilities or expenses in such proportion as is appropriate to reflect (i) the relative benefits received by the Indemnifying Person or Persons on the one hand and the Indemnified Person or Persons on the other from the offering of the Notes 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 Person or Persons on the one hand and the Indemnified Person or Persons on the other in connection with the misstatements or omissions or alleged misstatements or omissions that 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 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 Participant 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 misstatement or omission, and any other equitable considerations appropriate in the circumstances. (e) The parties agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Participants were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages, judgments, liabilities and expenses referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any reasonable legal or other expenses actually incurred by such Indemnified Person in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall a Participant be required to contribute any amount in excess of the amount by which proceeds received by such Participant from sales of Registrable Notes or Exchange Notes, as the case may be, exceeds the amount of any damages that such Participant has otherwise been required to pay or has paid 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. 30 (f) Any losses, claims, damages, liabilities or expenses for which an Indemnified Person is entitled to indemnification or contribution under this Section 7 shall be paid by the Indemnifying Person to the Indemnified Person as such losses, claims, damages, liabilities or expenses are incurred. The indemnity and contribution agreements contained in this Section 7 and the representations and warranties of the Issuers set forth in this Agreement shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of any Holder or any person who controls a Holder, the Issuers, and their respective directors, officers, employees or agents or any person controlling the Issuers, and (ii) any termination of this Agreement. (g) The indemnity and contribution agreements contained in this Section 7 will be in addition to any liability which the Indemnifying Persons may otherwise have to the Indemnified Persons referred to above. 8. Rules 144 and 144A The Issuers covenant and agree that, so long as Registrable Notes remain outstanding, it will file the reports required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted by the SEC thereunder in a timely manner in accordance with the requirements of the Securities Act and the Exchange Act and, if at any time the Issuers are not required or permitted to file such reports, the Issuers will, upon the request of any Holder or beneficial owner of Registrable Notes, make available such information necessary to permit sales pursuant to Rules 144 and 144A under the Securities Act. The Issuers further covenant for so long as any Registrable Notes remain outstanding, to make available to any Holder or beneficial owner of Registrable Notes in connection with any sale thereof and any prospective purchaser of such Registrable Notes from such Holder or beneficial owner the information required by Rule 144A(d)(4) under the Securities Act in order to permit resales of such Registrable Notes pursuant to Rule 144A.
