2.       EXCHANGE OFFER

                  (a)      The Issuers shall file with the SEC, to the extent
not prohibited by any applicable law or applicable interpretation of the staff
of the SEC no later than the Filing Date, a Registration Statement on an
appropriate registration form (the "Exchange Offer Registration Statement") with
respect to a registered offer (the "Exchange Offer") to exchange any and all of
the Registrable Securities (other than the Private Exchange Securities, if any)
for a like aggregate principal amount of debt securities of the Company that are
identical in all material respects to the Securities ( the "Exchange Notes" and,
together with the guarantees thereon, the "Exchange Securities") (and that are
entitled to the benefits of the Indenture or a trust indenture that is identical
in all material respects to the Indenture (other than such changes to the
Indenture or any such identical trust indenture as are necessary to comply with
any requirements of the SEC to effect or maintain the qualification thereof
under the TIA) and that, in either case, has been qualified under the TIA),
except that the Exchange Securities (other than Private Exchange Securities, if
any) shall have been registered pursuant to an effective Registration Statement
under the Securities Act and shall contain no restrictive legend thereon. The
Exchange Offer shall comply with all applicable tender offer rules and
regulations under the Exchange Act. The Issuers agree to use their reasonable
best 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 not less than 30 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
210th day following the Issue Date; provided, however, that if such 210th day
would otherwise fall on a day that is not a Business Day, then such Exchange
Offer must be consummated not later than

<PAGE>

                                       -6-

the next succeeding Business Day. If after such Exchange Offer Registration
Statement is declared effective by the SEC, the Exchange Offer or the issuance
of the Exchange Securities thereunder is interfered with by any stop order,
injunction or other order or requirement of the SEC or any other governmental
agency or court, such Exchange Offer Registration Statement shall be deemed not
to have become effective for purposes of this Agreement during the period of
such interference until the Exchange Offer may legally resume.

                  Each Holder (including, without limitation, each Participating
Broker-Dealer) who participates in the Exchange Offer will be required to
represent to the Issuers in writing (i) that any Exchange Securities received by
it will be acquired in the ordinary course of its business, (ii) that at the
time of the commencement of the Exchange Offer such Holder has no arrangement or
understanding with any Person to participate in the distribution (within the
meaning of the Securities Act) of the Exchange Securities in violation of the
provisions of the Securities Act, (iii) that such Holder is not an "affiliate"
(as defined in Rule 405 promulgated under the Securities Act) of the Company or
the Guarantors within the meaning of the Securities Act and is not acting on
behalf of any persons or entities who could not truthfully make the foregoing
representations, (iv) if such Holder is not a broker-dealer, that it is not
engaged in, and does not intend to engage in, the distribution of Exchange
Securities, and (v) if such Holder is a broker-dealer (a "Participating
Broker-Dealer"), that it will receive Exchange Securities for its own account in
exchange for Securities that were acquired as a result of market-making or other
trading activities and that it will deliver a prospectus in connection with any
resale of such Exchange Securities.

                  Upon consummation of the Exchange Offer in accordance with
this Section 2, the provisions of this Agreement shall continue to apply,
mutatis mutandis, solely with respect to Registrable Securities that are Private
Exchange Securities and Exchange Securities held by Participating
Broker-Dealers, and the Company shall have no further obligation to register
Registrable Securities (other than Private Exchange Securities and other than in
respect of any Exchange Securities as to which clause 2(c)(v) hereof applies)
pursuant to Section 3 hereof. No securities other than the Exchange Securities
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 Initial Purchasers, that 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
Participating Broker-Dealer that is the beneficial owner (as defined in Rule
13d-3 under the Exchange Act) of Exchange Securities received by such
Participating Broker-Dealer in the Exchange Offer, whether such positions or
policies have been publicly disseminated by the staff of the SEC or such
positions or policies, in the judgment of the Initial Purchasers, 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

<PAGE>

                                      -7-

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 Securities in compliance
with the Securities Act.

                  The Issuers shall use their respective reasonable 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 is necessary to
comply with applicable law in connection with any resale of the Exchange
Securities covered thereby; provided, however, that such period shall not be
required to exceed 90 days or such longer period if extended pursuant to the
last paragraph of Section 5 hereof (the "Applicable Period").

                  If, prior to consummation of the Exchange Offer, any Initial
Purchaser holds any Securities acquired by it and having, or that are reasonably
likely to be determined to have, the status of an unsold allotment in the
initial distribution, the Issuers, upon the request of such Initial Purchaser
simultaneously with the delivery of the Exchange Securities in the Exchange
Offer, shall issue and deliver to such Initial Purchaser in exchange (the
"Private Exchange") for such Securities held by such Initial Purchaser a like
principal amount of debt securities of the Issuers that are identical in all
material respects to the Exchange Securities (the "Private Exchange Notes" and,
together with the guarantees thereon, the "Private Exchange Securities"), except
for the placement of a restrictive legend on such Private Exchange Securities.
The Private Exchange Securities shall be issued pursuant to the same indenture
as the Exchange Securities and bear the same CUSIP number as the Exchange
Securities if permitted by the CUSIP Service Bureau.

                  Interest on each Exchange Note will accrue (A) from the later
of (i) the last interest payment date on which interest was paid on the Note
surrendered in exchange therefor, or (ii) if the Note is surrendered for
exchange on a date in a period that includes 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 date or (B) if no
interest has been paid on such Note, from the Issue Date.

                  In connection with the Exchange Offer, the Issuers shall:

                  (1)      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;

<PAGE>

                                      -8-

                  (2)      use their respective reasonable best efforts to keep
         the Exchange Offer open for not less than 30 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 Securities 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; 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
or the Private Exchange, as the case may be, the Issuers shall:

                  (1)      accept for exchange all Registrable Securities
         properly tendered and not validly withdrawn pursuant to the Exchange
         Offer or the Private Exchange;

                  (2)      deliver to the Trustee for cancellation all
         Registrable Securities so accepted for exchange; and

                  (3)      cause the Trustee to authenticate and deliver
         promptly to each Holder of Securities, Exchange Securities or Private
         Exchange Securities, as the case may be, equal in principal amount to
         the Securities of such Holder so accepted for exchange; provided that,
         in the case of any Notes held in global form by a depositary,
         authentication and delivery to such depositary of one or more
         replacement Notes in global form in an equivalent principal amount
         thereto for the account of such Holders in accordance with the
         Indenture shall satisfy such authentication and delivery requirement.

                  The Exchange Securities and the Private Exchange Securities
may be issued under (i) the Indenture or (ii) an indenture identical in all
material respects to the Indenture, which in either event has been qualified
under the TIA or is exempt from such qualification and shall provide that (1)
the Exchange Securities shall not be subject to the transfer restrictions set
forth in the Indenture and (2) the Private Exchange Securities shall be subject
to the transfer restrictions set forth in the Indenture. The Indenture or such
indenture described in (ii) above shall provide that the Exchange Securities,
the Private Exchange Securities and the Securities shall vote and consent
together on all matters as one class and that none of the Exchange Securities,
the Private Exchange Securities or the Securities 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 an Exchange Offer, (ii) the Exchange Offer is not
consummated within 210 days of the Issue Date; provided, however, that if such
210th day would otherwise fall on a day that is not a Business Day, then such
Exchange Offer must be consummated not later than the next succeeding Business
Day (provided that if the Exchange Offer shall be consummated after such 210-day
period, then the Issuers' obligation under this clause (ii) arising from the
failure of the Exchange Offer to be consummated within such 210-day period shall
terminate), (iii) the holder of Private Exchange Securities so requests at any
time within 90 days after the consummation of the Private Exchange, (iv) because
of any changes in law or in currently prevailing interpretations of the staff of
the SEC, a Holder (other than an Initial Purchaser holding Securities acquired
directly from the Issuers) is not permitted to participate in the Exchange Offer
or (v) in the case of any Holder that participates in the Exchange Offer, such
Holder does not receive Exchange Securities on the date of the exchange that may
be sold without restriction under state and federal securities laws (other than
due solely to the status of such Holder as an affiliate of the Company or any of
the Guarantors within the meaning of the Securities Act), then the Company shall
promptly deliver written notice thereof (the "Shelf Notice") to the Trustee and
in the case of clauses (i), (ii) and (iv), all Holders, in the case of clause
(iii), the Holders of the Private Exchange Securities and in the case of clause
(v), the affected Holder, shall file a Shelf Registration Statement pursuant to
Section 3 hereof.

3.       SHELF REGISTRATION

                  If 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 Securities
         not exchanged in the Exchange Offer, Private Exchange Notes and
         Exchange Notes as to which Section 2(c)(iv) is applicable (the "Shelf
         Registration Statement"). The Issuers shall use their respective
         reasonable best efforts to file with the SEC the Shelf Registration
         Statement on or prior to the applicable Filing Date. The Shelf
         Registration Statement shall be on Form S-1 or another appropriate form
         permitting registration of such Registrable Securities for resale by
         Holders in the 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 Securities to be
         included in the Shelf Registration Statement.

                  The Issuers shall use their respective reasonable best efforts
         to cause the Shelf Registration Statement to be declared effective
         under the Securities Act on or prior to the Effectiveness Date and to
         keep the Shelf Registration Statement continuously effective under the
         Securities Act until the date that is two years from the Issue Date or
         such shorter period ending when all Registrable Securities covered by
         the Shelf Regis-

<PAGE>

                                      -10-

         tration Statement have been sold in the manner set forth and as
         contemplated in the Shelf Registration Statement or cease to be
         outstanding (the "Effectiveness Period"); provided, however, that the
         Effectiveness Period in respect of the Shelf Registration Statement
         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.

                  In the event that a Shelf Registration Statement is filed, the
         Issuer shall provide to each Holder copies of the prospectus that is
         part of the Shelf Registration Statement, notify each such Holder when
         the Shelf Registration Statement for the Registrable Securities covered
         by the Shelf Registration Statement has become effective and take
         certain other actions as are required to permit unrestricted resales of
         the Registrable Securities covered by the Shelf Registration Statement.
         A Holder that sells Registrable Securities covered by the Shelf
         Registration Statement pursuant to the Shelf Registration Statement
         will be (x) required to be named as a selling security holder in the
         related prospectus and to deliver a prospectus to purchasers, (y)
         subject to certain of the civil liability provisions under the
         Securities Act in connection with such sales and (z) bound by the
         provisions of this Agreement that are applicable to such a Holder
         (including Section 7 hereof).

                  (b)      Withdrawal of Stop Orders. If the Shelf Registration
         Statement 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 best efforts to obtain the prompt withdrawal of any order
         suspending the effectiveness thereof.

                  (c)      Supplements and Amendments. The Issuers shall
         promptly supplement and amend the Shelf Registration Statement if
         required by the rules, regulations or instructions applicable to the
         registration form used for such Shelf Registration Statement, if
         required by the Securities Act, or if reasonably requested by the
         Holders of a majority in aggregate principal amount of the Registrable
         Securities covered by such Registration Statement or by any underwriter
         of such Registrable Securities.

4.       ADDITIONAL INTEREST

                  (a)      The Issuers and the Initial Purchasers agree that the
Holders of Registrable Securities will suffer damages if the Issuers fail to
fulfill their respective 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 Securities ("Additional Interest") under the
circumstances and to the extent set forth below (without duplication):

<PAGE>

                                      -11-

                  (i)      if (A) neither the Exchange Offer Registration
         Statement nor the Shelf Registration Statement has been filed on or
         prior to 90 days after the Issue Date or (B) notwithstanding that the
         Issuers have consummated or will consummate the Exchange Offer, the
         Issuers are required to file a Shelf Registration Statement and such
         Shelf Registration Statement 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 Securities over
         and above the stated interest at a rate of 0.5% per annum for the first
         90 days immediately following the Filing Date, such Additional Interest
         rate increasing by an additional 0.5% per annum at the beginning of
         each subsequent 90-day period;

                  (ii)     if (A) neither the Exchange Offer Registration
         Statement nor the Initial Shelf Registration Statement is declared
         effective by the SEC on or prior to 180 days after the Issue Date or
         (B) notwithstanding that the Issuers have consummated or will
         consummate the Exchange Offer, the Issuers are required to file a Shelf
         Registration Statement and such Shelf Registration Statement is not
         declared effective by the SEC on or prior to the 90th day following the
         date such Shelf Registration Statement was filed, then, commencing on
         the day after such required effective 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 each such filing date, such
         Additional Interest rate increasing by an additional 0.5% per annum at
         the beginning of each subsequent 90-day period; and

                  (iii)    if either (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 210th day after the date on which
         the Exchange Offer Registration Statement was declared effective;
         provided, however, that if such 210th day would otherwise fall on a day
         that is not a Business Day, then such Exchange Offer must be
         consummated not later than the next succeeding Business Day or (B) if
         applicable, a Shelf Registration Statement has been declared effective
         and such Shelf Registration Statement ceases to be effective at any
         time prior to the second anniversary of the Issue Date (other than
         after such time as all Notes have been disposed of thereunder), 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 (x) the
         211th 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, such Additional Interest rate increasing 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 Securities may not
accrue under more than one of the foregoing clauses (i) through (iii) of this
Section 4(a) at the same time and at no time shall the aggregate amount of
Additional Interest accruing exceed at any one time in the aggregate 1.0% per
annum; and provided, further, however, that (1) upon the filing

<PAGE>

                                      -12-

of the Exchange Offer Registration Statement or a Shelf Registration Statement
(in the case of clause (i) of this Section 4(a)), (2) upon the effectiveness of
the Exchange Offer Registration Statement or the Shelf Registration Statement
(in the case of clause (ii) of this Section 4(a)), or (3) upon the exchange of
Exchange Securities for all Securities tendered (in the case of clause (iii)(A)
of this Section 4(a)), or upon the effectiveness of the applicable Shelf
Registration Statement that had ceased to remain effective (in the case of
(iii)(B) of this Section 4(a)), Additional Interest on the Securities as a
result of such clause (or the relevant subclause thereof), as the case may be,
shall cease to accrue.

                  (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 each January 1 and July 1,
commencing January 1, 2004, (to the holders of record on the December 15 and
June 15 immediately preceding such dates), the same original interest dates as
the Securities, commencing with the first such 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 Securities, 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
consisting 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 Filing
         Date, a Registration Statement or Registration Statements as prescribed
         by Sections 2 or 3 hereof, and use its reasonable best 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
         an 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 Securities
         during the Applicable Period, 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 Securities
         covered by such Registration Statement or each such Participating
         Broker-Dealer, as the case may be, their

<PAGE>

                                      -13-

         counsel and the managing underwriters, if any, a reasonable opportunity
         to review copies of all such documents (including copies of any
         documents to be incorporated by reference therein and all exhibits
         thereto) proposed to be filed (in each case at least three Business
         Days prior to such filing). 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
         Securities covered by such Registration Statement, or any such
         Participating Broker-Dealer, as the case may be, or their counsel, or
         the managing underwriters, if any, shall reasonably object on a timely
         basis.

                  (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, 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 in all material
         respects 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 respective reasonable best efforts to keep a Registration
         Statement effective during the Applicable Period if each of the Issuers
         voluntarily takes any action that would result in selling Holders of
         the Registrable Securities covered thereby or Participating
         Broker-Dealers seeking to sell Exchange Securities not being able to
         sell such Registrable Securities or such Exchange Securities during
         that period, unless such action is required by applicable law or unless
         the Issuers comply in all material respects with this Agreement,
         including without limitation, the provisions of paragraph 5(k) hereof
         and the last paragraph of this Section 5.

                  (c)      If (1) a Shelf Registration Statement is filed
         pursuant to Section 3 hereof or (2) a Prospectus contained in an
         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 Securities
         during the Applicable Period, the Company shall notify the selling
         Holders of Registrable Securities, or each such Participating
         Broker-Dealer, as the case may be, their counsel and the managing
         underwriters, if any, promptly (but in any event within two Business
         Days) and 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

<PAGE>

                                      -14-

         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 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 Securities or resales of
         Exchange Securities by Participating Broker-Dealers the representations
         and warranties of the Issuers contained in any agreement (including any
         underwriting agreement), contemplated by Section 5(n) hereof cease to
         be true and correct, (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 Securities or the Exchange Securities to be sold by any
         Participating Broker-Dealer for offer or sale in any jurisdiction, or
         the initiation or written threat of any proceeding for such purpose,
         (v) of the happening of any event, the existence of any condition or
         any information becoming known 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 respects or that requires the making of any material
         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 or omit to state any material fact required to be
         stated therein or necessary to make the statements therein, in the
         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)      Use their respective reasonable best 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 Securities or the Exchange
         Securities for sale in any jurisdiction and, if any such order is
         issued, to use their reasonable best efforts to obtain the withdrawal
         of any such order at the earliest possible moment.

                  (e)      If a Shelf Registration Statement is filed pursuant
         to Section 3 and if requested by the managing underwriter or
         underwriters, if any, or the Holders of a majority in aggregate
         principal amount of the Registrable Securities being sold in connection
         with an underwritten offering, (i) promptly incorporate in a prospectus
         supplement or post-effective amendment such information as the managing
         underwriter or

<PAGE>

                                      -15-

         underwriters, if any, such Holders or counsel for any of them determine
         is reasonably necessary to be included therein, (ii) make all required
         filings of such prospectus supplement or such post-effective amendment
         as soon as practicable after the Issuers have received notification of
         the matters to be incorporated in such prospectus supplement or
         post-effective amendment and (iii) supplement or make amendments to
         such Registration Statement; provided, however, that the Issuers shall
         not be required to take any action pursuant to this Section 5(e) that
         would, in the opinion of counsel for the Issuers, violate applicable
         law.

                  (f)      If (1) a Shelf Registration Statement is filed
         pursuant to Section 3 hereof or (2) a Prospectus contained in an
         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 Securities
         during the Applicable Period, furnish to each selling Holder of
         Registrable Securities and to each such Participating Broker-Dealer who
         so requests and to their respective 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 Statement is filed
         pursuant to Section 3 hereof or (2) a Prospectus contained in an
         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 Securities
         during the Applicable Period, deliver to each selling Holder of
         Registrable Securities, 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 Securities 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 Securities covered by, or the sale by
         Participating Broker-Dealers of the Exchange Securities pursuant to,
         such Prospectus and any amendment or supplement thereto.

                  (h)      Prior to any public offering of Registrable
         Securities or Exchange Securities or any delivery of a Prospectus
         contained in the Exchange Offer Registration Statement by any
         Participating Broker-Dealer who seeks to sell Exchange Securities
         during the Applicable Period, to use their reasonable best efforts to
         register or qualify

<PAGE>

                                      -16-

         and to cooperate with the selling Holders of Registrable Securities or
         each such Participating Broker-Dealer, as the case may be, the managing
         underwriter or underwriters, if any, and their respective counsel in
         connection with the registration or qualification (or exemption from
         such registration or qualification) of such Registrable Securities for
         offer and sale under the securities or Blue Sky laws of such
         jurisdictions within the United States as any selling Holder,
         Participating Broker-Dealer or the managing underwriter or underwriters
         reasonably request in writing; provided, however, that where Exchange
         Securities held by Participating Broker-Dealers or Registrable
         Securities are offered other than through an underwritten offering, the
         Issuers agree to cause their counsel to perform Blue Sky investigations
         and file registrations and qualifications required to be filed pursuant
         to this Section 5(h); use their reasonable best efforts to keep each
         such registration or qualification (or exemption therefrom) effective
         during the period such Registration Statement is required to be kept
         effective and do any and all other acts or things reasonably necessary
         or advisable to enable the disposition in such jurisdictions of the
         Exchange Securities held by Participating Broker-Dealers or the
         Registrable Securities covered by the applicable Registration
         Statement; provided, however, that none of the Issuers shall be
         required to (A) qualify generally to do business in any jurisdiction
         where it is not then so qualified, (B) take any action that would
         subject it to general service of process in any such jurisdiction where
         it is not then so subject or (C) subject itself to taxation in any such
         jurisdiction where it is not then so subject.

                  (i)      If a Shelf Registration Statement is filed pursuant
         to Section 3 hereof, cooperate with the selling Holders of Registrable
         Securities and the managing underwriter or underwriters, if any, to
         facilitate the timely preparation and delivery of certificates
         representing Registrable Securities 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 Securities to be in such denominations and registered in
         such names as the managing underwriter or underwriters, if any, or
         Holders may reasonably request.

                  (j)      Use their respective reasonable best efforts to cause
         the Registrable Securities covered by the Registration Statement to be
         registered with or approved by such other governmental agencies or
         authorities as may be necessary to enable the Holders thereof or the
         underwriter or underwriters, if any, to consummate the disposition of
         such Registrable Securities, except as may be required solely as a
         consequence of the nature of such selling Holder's business, in which
         case the Issuers will cooperate in all reasonable respects with the
         filing of such Registration Statement and the granting of such
         approvals.

                  (k)      If (1) a Shelf Registration Statement is filed
         pursuant to Section 3 hereof or (2) a Prospectus contained in an
         Exchange Offer Registration Statement filed

                                      -17-

         pursuant to Section 2 hereof is required to be delivered under the
         Securities Act by any Participating Broker-Dealer who seeks to sell
         Exchange Securities during the Applicable Period, upon the occurrence
         of any event contemplated by paragraph 5(c)(v) or 5(c)(vi) hereof, as
         promptly as practicable, prepare and (subject to Section 5(a) hereof)
         file with the SEC, at the Issuers' sole expense, a supplement or
         post-effective amendment to the Registration Statement or a supplement
         to the related Prospectus or any document incorporated or deemed to be
         incorporated therein by reference, or file any other required document
         so that, as thereafter delivered to the purchasers of the Registrable
         Securities being sold thereunder or to the purchasers of the Exchange
         Securities to whom such Prospectus will be delivered by a Participating
         Broker-Dealer, any such Prospectus will not contain an untrue statement
         of a material fact or omit to state a material fact required to be
         stated therein or necessary to make the statements therein, in the
         light of the circumstances under which they were made, not misleading.

                  (l)      Use its respective reasonable best efforts to cause
         the Registrable Securities covered by a Registration Statement or the
         Exchange Securities, as the case may be, to be rated with the
         appropriate rating agencies, if so requested by the Holders of a
         majority in aggregate principal amount of Registrable Securities
         covered by such Registration Statement or the Exchange Securities, as
         the case may be, or the managing underwriter or underwriters, if any.

                  (m)      Prior to the effective date of the first Registration
         Statement relating to the Registrable Securities, (i) provide the
         Trustee with certificates for the Registrable Securities or Exchange
         Securities, as the case may be, in a form eligible for deposit with
         Euroclear and Clearstream and (ii) provide a CUSIP number for the
         Registrable Securities or Exchange Securities, as the case may be.

                  (n)      In connection with any underwritten offering of
         Registrable Securities pursuant to a Shelf Registration Statement,
         enter into an underwriting agreement as is customary in underwritten
         offerings of debt securities similar to the Securities and take all
         such other actions as are reasonably requested by the managing
         underwriter or underwriters in order to expedite or facilitate the
         registration or the disposition of such Registrable Securities and, in
         such connection, (i) make such representations and warranties to, and
         covenants with, the underwriters with respect to the business of the
         Issuers and their subsidiaries (including any acquired business,
         properties or entity, if applicable) and the Registration Statement,
         Prospectus and documents, if any, incorporated or deemed to be
         incorporated by reference therein, in each case, as are customarily
         made by issuers to underwriters in underwritten offerings of debt
         securities similar to the Securities, and confirm the same in writing
         if and when requested; (ii) obtain the written opinion of counsel to
         the Issuers and written updates thereof in form, scope and substance
         reasonably satisfactory to the managing underwriter or underwriters,
         addressed to the underwriters covering the matters customarily covered
         in opinions re-

<PAGE>

                                      -18-

         quested in underwritten offerings of debt similar to the Securities and
         such other matters as may be reasonably requested by the managing
         underwriter or underwriters; (iii) obtain "cold comfort" letters and
         updates thereof in form, scope and substance reasonably satisfactory to
         the managing underwriter or underwriters from the independent certified
         public accountants of the Issuers (and, if necessary, any other
         independent certified public accountants of any subsidiary of the
         Issuers or of any business acquired by the Issuers for which financial
         statements and financial data are, or are required to be, included or
         incorporated by reference in the Registration Statement), addressed to
         each of the underwriters, such letters to be in customary form and
         covering matters of the type customarily covered in "cold comfort"
         letters in connection with underwritten offerings of debt securities
         similar to the Securities and such other matters as reasonably
         requested by the managing underwriter or underwriters; and (iv) if an
         underwriting agreement is entered into, the same shall contain
         indemnification provisions and procedures no less favorable than those
         set forth in Section 7 hereof (or such other provisions and procedures
         acceptable to Holders of a majority in aggregate principal amount of
         Registrable Securities covered by such Registration Statement and the
         managing underwriter or underwriters or agents) with respect to all
         parties to be indemnified pursuant to said Section. The above shall be
         done at each closing under such underwriting agreement, or as and to
         the extent required thereunder.

                  (o)      If (1) a Shelf Registration Statement is filed
         pursuant to Section 3 hereof or (2) a Prospectus contained in an
         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 Securities
         during the Applicable Period, upon reasonable advance notice make
         available for inspection by any selling Holder of such Registrable
         Securities being sold, or each such Participating Broker-Dealer, as the
         case may be, any underwriter participating in any such disposition of
         Registrable Securities, 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 without interfering in the orderly business of the
         Issuers, all financial and other relevant 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 respective 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. Any such access granted to the Inspectors under this Section
         5(o) shall be subject to the prior receipt by the Issuers of written
         undertakings, in form and substance reasonably satisfactory to the
         Issuers, to preserve the confidentiality of any information deemed by
         the Issuers to be confidential. Records that the Issuers determine, in
         good faith, to be confidential and any Records that they notify the
         Inspectors are confidential shall not be disclosed

<PAGE>

                                      -19-

         by the Inspectors unless (i) the Issuers based upon advice of counsel
         determine that disclosure of such Records is necessary to avoid or
         correct a material misstatement or omission in such Registration
         Statement, (ii) the release of such Records is ordered pursuant to a
         subpoena or other order from a court of competent jurisdiction, (iii)
         after giving reasonable prior notice to the Company, disclosure of such
         information is, in the opinion of counsel for any Inspector, necessary
         or advisable in connection with any action, claim, suit or proceeding,
         directly or indirectly, involving or potentially involving such
         Inspector and arising out of, based upon, relating to or involving this
         Agreement or any transactions contemplated hereby or arising hereunder
         or (iv) the information in such Records has been made generally
         available to the public. Each selling Holder of such Registrable
         Securities 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 Company
         unless and until such information is generally available to the public.
         Each selling Holder of such Registrable Securities 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 Company and allow
         the Company to undertake appropriate action to prevent disclosure of
         the Records deemed confidential at the Issuers' sole expense.

                  (p)      Provide an indenture trustee for the Registrable
         Securities or the Exchange Securities, 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 Exchange Offer or the first Registration
         Statement relating to the Registrable Securities; and in connection
         therewith, cooperate with the trustee under any such indenture and the
         Holders of the Registrable Securities, 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 best 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.

                  (q)      Comply in all material respects with all applicable
         rules and regulations of the SEC and make generally available to its
         securityholders earning 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 Securities are sold to
         underwriters in a firm commitment or reasonable 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 ef-

<PAGE>

                                      -20-

         fective date of a Registration Statement, which statements shall cover
         said 12-month periods.

                  (r)      Upon consummation of an Exchange Offer or a Private
         Exchange, obtain an opinion of counsel to the Issuers, who may, at the
         Issuers' election, be internal counsel to the Issuers, in a form
         customary for underwritten transactions, addressed to the Trustee for
         the benefit of all Holders of Registrable Securities participating in
         the Exchange Offer or the Private Exchange, as the case may be, that
         the Exchange Securities or Private Exchange Securities, as the case may
         be, and the related indenture constitute legal, valid and binding
         obligations of the Issuers, enforceable against the Issuers in
         accordance with its respective terms, subject to customary exceptions
         and qualifications.

                  (s)      If an Exchange Offer or a Private Exchange is to be
         consummated, upon delivery of the Registrable Securities by Holders to
         the Company (or to such other Person as directed by the Company) in
         exchange for the Exchange Securities or the Private Exchange
         Securities, as the case may be, the Company shall mark, or cause to be
         marked, on such Registrable Securities that such Registrable Securities
         are being cancelled in exchange for the Exchange Securities or the
         Private Exchange Securities, as the case may be; in no event shall such
         Registrable Securities be marked as paid or otherwise satisfied.

                  (t)      Cooperate with each seller of Registrable Securities
         covered by any Registration Statement and each underwriter, if any,
         participating in the disposition of such Registrable Securities and
         their respective counsel in connection with any filings required to be
         made with the National Association of Securities Dealers, Inc. (the
         "NASD").

                  (u)      Use their respective reasonable best efforts to take
         all other steps necessary or advisable to effect the registration of
         the Registrable Securities covered by a Registration Statement
         contemplated hereby.

                  The Issuers may require each seller of Registrable Securities
as to which any registration is being effected to furnish to the Issuers such
information regarding such seller and the distribution of such Registrable
Securities as the Issuers may, from time to time, reasonably request. The
Issuers may exclude from such registration the Registrable Securities of any
seller who unreasonably fails to furnish such information within a reasonable
time after receiving such request and in such event shall have no further
obligation under this Agreement (including, without limitation, obligations
under Section 4 hereof) with respect to such seller or any subsequent holder of
such Registrable Securities. Each seller 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 the information previously
furnished to the Issuers by such seller not materially misleading.

<PAGE>

                                      -21-

                  Each Holder of Registrable Securities and each Participating
Broker-Dealer agrees by acquisition of such Registrable Securities or Exchange
Securities to be sold by such Participating Broker-Dealer, as the case may be,
that, upon actual receipt of any notice from the Company of the happening of any
event of the kind described in Sections 5(c)(ii), 5(c)(iv), 5(c)(v) or 5(c)(vi)
hereof, such Holder will forthwith discontinue disposition of such Registrable
Securities covered by such Registration Statement or Prospectus or Exchange
Securities to be sold by such Holder or Participating Broker-Dealer, as the case
may be, 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 Company that the
use of the applicable Prospectus may be resumed, and has received copies of any
amendments or supplements thereto. During any such discontinuance, no Additional
Interest shall accrue or otherwise be payable on the Registrable Securities. In
the event that the Company 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 Securities covered by such
Registration Statement or Exchange Securities 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.

6.       REGISTRATION EXPENSES

                  (a)      All fees and expenses incident to the performance of
or compliance with this Agreement by the Issuers shall be borne by the Issuers

Registrable Securities being registered in a Shelf Registration Statement for
the reasonable fees and disbursements of not more than one counsel chosen by the
Holders of a majority in aggregate principal amount of the Registrable

7.       INDEMNIFICATION

                  (a)      Each of the Issuers agrees to indemnify and hold
harmless each Holder of Registrable Securities offered pursuant to a Shelf
Registration Statement Statement and each Participating Broker-Dealer selling
Exchange Securities during the Applicable Period, the officers and directors of
each such Person or its affiliates, and each other Person, if any, who controls
any such Person or its affiliates 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 and liabilities (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 pursuant to which the offering of such Registrable Securities or
Exchange Securities, as the case may be, is registered (or any amendment
thereto) or related Prospectus (or any amendments or supplements thereto) or any
related 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 light of the
circumstances under which they were made, not misleading; provided, however,
that none of the Issuers will be required to indemnify a Participant if (i) such
losses, claims, damages or liabilities are caused by 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 Company
in writing by or on behalf of such Participant expressly for use therein or (ii)
if such Partici-

<PAGE>

                                      -23-

pant sold to the person asserting the claim the Registrable Securities or
Exchange Securities that are the subject of such claim and such untrue statement
or omission or alleged untrue statement or omission was contained or made in any
preliminary prospectus and corrected in the Prospectus or any amendment or
supplement thereto and the Prospectus does not contain any other untrue
statement or omission or alleged untrue statement or omission of a material fact
that was the subject matter of the related proceeding and such Participant
failed to deliver or provide a copy of the Prospectus (as amended or
supplemented) to such Person with or prior to the confirmation of the sale of
such Registrable Securities or Exchange Securities sold to such Person if
required by applicable law, unless such failure to deliver or provide a copy of
the Prospectus (as amended or supplemented) was a result of noncompliance by the
Company with Section 5 of this Agreement.

                  (b)      Each Participant agrees, severally and not jointly,
to indemnify and hold harmless the Company and each of the Guarantors, the
Company's directors and officers, each Guarantor's directors and officers 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 Company to each Participant, but only (i) with
reference to information relating to such Participant furnished to the Company
in writing by or on behalf of such Participant expressly for use in any
Registration Statement or Prospectus, any amendment or supplement thereto or any
preliminary prospectus or (ii) with respect to any untrue statement or
representation made by such Participant in writing to the Company. The liability
of any Participant under this paragraph shall in no event exceed the proceeds
received by such Participant from sales of Registrable Securities or Exchange
Securities 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 Person against whom such indemnity may be
sought (the "Indemnifying Person") in writing, and the Indemnifying Person, 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 Person 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 Person shall not relieve it of any obligation or liability that it
may have hereunder or otherwise (unless and only to the extent that such failure
directly results in the loss or compromise of any material rights or defenses by
the Indemnifying Person and the Indemnifying Person was not otherwise aware of
such action or claim). 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
Person and the Indemnified Person shall have mutually agreed in writing to the
contrary, (ii) the Indemnifying Person shall have failed within a reasonable
period of time to

<PAGE>

                                      -24-

retain counsel reasonably satisfactory to the Indemnified Person or (iii) the
named parties in any such proceeding (including any impleaded parties) include
both the Indemnifying Person and the Indemnified Person and representation of
both parties by the same counsel would be inappropriate due to actual or
potential differing interests between them. It is understood that, unless there
exists a conflict among Indemnified Persons, the Indemnifying Person shall not,
in connection with any one 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 Securities and Exchange Securities sold by all such Participants
and any such separate firm for the Company, its directors, its officers and such
control Persons of the Company shall be designated in writing by the Company.
The Indemnifying Person shall not be liable for any settlement of any proceeding
effected without its prior written consent, 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,
the Indemnifying Person 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 Person (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, and 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 any Indemnified Person.

                  (d)      If the indemnification provided for in the first and
second paragraphs 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 or liabilities 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, damages or liabilities in such proportion as is
appropriate to reflect 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 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 Par-

                                      -25-

ticipant 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.

                  (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 and liabilities 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 Securities
or Exchange Securities, 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.

                  (f)      The indemnity and contribution agreements contained
in this Section 7 will be in addition to any liability that the Indemnifying
Persons may otherwise have to the Indemnified Persons referred to above.

8.       RULE 144 AND 144A

                  The Issuers covenant that they 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 not required to file such reports, they will, upon the request
of any Holder of Registrable Securities, make publicly available annual reports
and such information, documents and other reports of the type specified in
Sections 13 and 15(d) of the Exchange Act. The Issuers further covenant for so
long as any Registrable Securities remain outstanding, to make available to any
Holder or beneficial owner of Registrable Securities in connection with any sale
thereof and any prospective purchaser of such Registrable Securities 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 Securities
pursuant to Rule 144A.

9.       UNDERWRITTEN REGISTRATIONS

                  If any of the Registrable Securities covered by any Shelf
Registration Statement are to be sold in an underwritten offering, the
investment banker or investment bankers and manager or managers that will manage
the offering will be selected by the Holders of a majority in aggregate
principal amount of such Registrable Securities included in such offering and
reasonably acceptable to the Issuers.

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

10.      MISCELLANEOUS

                  (a)      No Inconsistent Agreements. The Issuers have not
entered into, as of the date hereof, and shall not, after the date of this
Agreement, enter into any agreement with respect to any of the Company's
securities that is inconsistent with the rights granted to the Holders of
Registrable Securities in this Agreement or otherwise conflicts with the
provisions hereof. The Issuers have not entered and will not enter into any
agreement with respect to any of the Company's securities that will grant to any
Person piggy-back registration rights with respect to a Registration Statement.

                  (b)      Adjustments Affecting Registrable Securities. The
Issuers shall not, directly or indirectly, take any action with respect to the
Registrable Securities as a class that would adversely affect the ability of the
Holders of Registrable Securities to include such Registrable Securities in a
registration undertaken pursuant to this Agreement.

                  (c)      Amendments and Waivers. The provisions of this
Agreement may not be amended, modified or supplemented, and waivers or consents
to departures from the provisions hereof may not be given, otherwise than with
the prior written consent of the Holders of not less than a majority in
aggregate principal amount of the then outstanding Registrable Securities.
Notwithstanding the foregoing, a waiver or consent to depart from the provisions
hereof with respect to a matter that relates exclusively to the rights of
Holders of Registrable Securities whose securities are being sold pursuant to a
Registration Statement and that does not directly or indirectly affect, impair,
limit or compromise the rights of other Holders of Registrable Securities may be
given by Holders of at least a majority in aggregate principal amount of the
Registrable Securities being sold by such Holders pursuant to such Registration
Statement; provided, however, that the provisions of this sentence may not be
amended, modified or supplemented except in accordance with the provisions of
the immediately preceding sentence.

                  (j)      Securities Held by the Issuers or their Affiliates.
Whenever the consent or approval of Holders of a specified percentage of
Registrable Securities is required hereunder, Registrable Securities held by the
Issuers or their affiliates (as such term is defined in Rule 405 under the
Securities Act) shall not be counted in determining whether such consent or
approval was given by the Holders of such required percentage.
