REGISTRATION RIGHTS AGREEMENT    
    


        This Registration Rights Agreement (this "Agreement") is dated as of March 8, 2004, by and between First
Horizon Pharmaceutical Corporation, a Delaware corporation (the "Company"), and Deutsche Bank Securities Inc. and UBS Securities LLC (together,
the "Initial Purchasers"). 


        This
Agreement is entered into in connection with that certain Purchase Agreement, dated March 2, 2004 (the "Purchase Agreement"),
by and between the Company and the Initial Purchasers, which provides for the sale by the Company to the Initial Purchasers of $125 million aggregate principal amount of the Company's 1.75%
Contingent Convertible Senior Subordinated Notes Due 2024 (the "Firm Notes"), which are convertible into common stock, par value $0.001 per share, of
the Company (the "Underlying Shares"), plus up to an additional $25 million aggregate principal amount of the same which the Initial Purchasers
may subsequently elect to purchase pursuant to the terms of the Purchase Agreement (the "Option Notes" and, together with the Firm Notes, the
"Notes"). The Notes are being issued pursuant to an Indenture dated as of the date hereof (the
"Indenture"), by and between the Company and Deutsche Bank Trust Company Americas, as Trustee.

2.    Shelf Registration. 


        (a)   Shelf Registration. The Company 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 (the "Initial Shelf Registration") on or prior to the Filing
Date. 


        The
Initial Shelf Registration shall be on Form S-3 or another appropriate form permitting registration of such Registrable Securities for resale by Holders in the
manner or manners designated by them (excluding Underwritten Offerings). The Company shall not permit any securities other than the Registrable Securities to be included in the Initial Shelf
Registration or any Subsequent Shelf Registration (as defined below). 


        The
Company shall use all 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
such Initial Shelf Registration continuously effective under the Securities Act until the date that is two years after the Closing Date (such period, as it may be shortened pursuant to clauses (i),
(ii) or (iii) immediately following, the "Effectiveness Period"), or such shorter period ending when (i) all of the Registrable
Securities covered by the Initial Shelf Registration have been sold in the manner set forth and as contemplated in the Initial Shelf Registration, (ii) the date on which all the Registrable
Securities 


3





 



(x) held
by Persons who are not affiliates of the Company may be resold pursuant to Rule 144(k) under the Securities Act or (y) cease to be outstanding, or (iii) a
Subsequent Shelf Registration covering all of the Registrable Securities has been declared effective under the Securities Act. 



        (b)   Subsequent Shelf Registrations. If the Initial Shelf Registration or any Subsequent Shelf Registration (as defined below)
ceases to be effective for any reason at any time during the Effectiveness Period (other than because of the sale of all of the Registrable Securities registered thereunder), the Company shall use all
reasonable efforts to obtain the prompt withdrawal of any order suspending the effectiveness thereof, and in any event shall within 45 days of 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 Securities (a "Subsequent Shelf Registration"). If a Subsequent Shelf Registration is filed, the Company shall use all 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 Registration Statement continuously
effective for a period equal to the number of days in the Effectiveness Period less the aggregate number of days during which the Initial Shelf Registration or 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 and the term "Shelf Registration Statement" means any Registration Statement filed in connection with a Shelf Registration. 



        (c)   Supplements and Amendments. The Company shall promptly supplement and amend the 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. 


        (d)   Notice and Questionnaire. Each Holder agrees that if such Holder wishes to sell Registrable Securities pursuant to a
Shelf Registration Statement and related Prospectus, it will do so only in accordance with this Section 2(d) and Section 4 hereof. Each Holder wishing to sell Registrable Securities
pursuant to a Shelf Registration Statement and related Prospectus agrees to deliver a Notice and Questionnaire to the Company at least five (5) Business Days prior to any intended distribution
of Registrable Securities under the Shelf Registration Statement. From and after the date the Initial Shelf Registration Statement is declared effective, the Company shall, as promptly as practicable
after the date a Notice and Questionnaire is delivered, and in any event upon the later of (x) five (5) Business Days after such date or (y) five (5) Business Days after
the expiration of any Deferral Period in effect when the Notice and Questionnaire is delivered or put into effect within five (5) Business Days of such delivery date: 



          (i)  if
required by applicable law, file with the SEC a post-effective amendment to the Shelf Registration Statement or prepare and, if required by applicable
law, file a supplement to the related Prospectus or a supplement or amendment to any document incorporated therein by reference or file any other required document so that the Holder delivering
such Notice and Questionnaire is named as a selling securityholder in the Shelf Registration Statement and the related Prospectus in such a manner as to permit such Holder to deliver such Prospectus
to purchasers of the Registrable Securities in accordance with applicable law and, if the Company shall file a post-effective amendment to the Shelf Registration Statement, use all
reasonable efforts to cause such post-effective amendment to be declared effective under the Securities Act as promptly as is practicable, but in any event by the date (the
"Amendment Effectiveness Deadline Date") that is forty-five (45) days after the date such post-effective amendment is
required by this clause to be filed; 


         (ii)  provide
such Holder copies of any documents filed pursuant to Section 2(d)(i); and 


        (iii)  notify
such Holder as promptly as practicable after the effectiveness under the Securities Act of any post-effective amendment filed pursuant to
Section 2(d)(i); provided that if such Notice 



4





 




and
Questionnaire is delivered during a Deferral Period (as defined in Section 3(b)), the Company shall so inform the Holder delivering such Notice and Questionnaire and shall take the actions
set forth in clauses (i), (ii) and (iii) above upon expiration of the Deferral Period. Notwithstanding anything contained herein to the contrary, (i) the Company shall be under no
obligation to name any Holder that has not delivered a Notice and Questionnaire to the Company in accordance with this Section 2(d) and (ii) the Amendment Effectiveness Deadline Date
shall be extended by up to ten (10) Business Days from the expiration of a Deferral Period (and the Company shall incur no obligation to pay Liquidated Damages during such extension) if such
Deferral Period shall be in effect on the Amendment Effectiveness Deadline Date. 




3.    Liquidated Damages. 


        (a)   The
Company and the Initial Purchasers agree that the Holders of Registrable Securities will suffer damages if the Company fails to fulfill certain of its obligations
under Section 2 hereof or otherwise permits certain circumstances to exist and that it would not be feasible to ascertain the extent of such damages with precision. Accordingly, the Company
agrees to pay liquidated damages on the Registrable Securities ("Liquidated Damages") under the circumstances and to the extent set forth below (each of
which shall be given independent effect; each a "Registration Default"): 



          (i)  if
the Initial Shelf Registration is not filed on or prior to the Filing Date, then commencing on the day after the Filing Date, Liquidated Damages shall accrue on the
Registrable Securities at a rate of 0.50% per annum on the Amount of Registrable Securities; 


         (ii)  if
the Initial Shelf Registration or Subsequent Shelf Registration is not declared effective by the SEC on or prior to the Effectiveness Date, then commencing on the
day after the Effectiveness Date, Liquidated Damages shall accrue on the Registrable Securities at a rate of 0.50% per annum on the Amount of Registrable Securities; and 



        (iii)  if
a Shelf Registration has been declared effective and such Shelf Registration ceases to be effective at any time during the Effectiveness Period (other than as
permitted under Section 3(b)), then commencing on the day after the date such Shelf Registration ceases to be effective, Liquidated
Damages shall accrue on the Registrable Securities at a rate of 0.50% per annum on the Amount of Registrable Securities; 




provided,
however, that Liquidated Damages on the Registrable Securities may not accrue under more than one of the foregoing clauses (i), (ii) or (iii) at any one time; and provided
further, however, that (1) upon the filing of the Initial Shelf Registration as required hereunder (in the case of clause (a)(i) of this Section 3), (2) upon the
effectiveness of the Initial Shelf Registration or Subsequent Shelf Registration as required hereunder (in the case of clause (a)(ii) of this Section 3), or (3) upon the
effectiveness of a Shelf Registration which had ceased to remain effective (in the case of (a)(iii) of this Section 3), Liquidated Damages on the Registrable Securities as a result of
such clause (or the relevant subclause thereof), as the case may be, shall cease to accrue. It is understood and agreed that, notwithstanding any provision to the contrary, no Liquidated Damages shall
accrue on any Registrable Securities that are then covered by an effective Shelf Registration Statement. 


        (b)   Notwithstanding
paragraph (a) of this Section 3, the Company, upon written notice to the Holders, shall be permitted to suspend the effectiveness of a
Registration Statement covering the Registrable Securities for any bona fide reason whatsoever for up to 45 consecutive days (the "Deferral Period") in
any 90 day period without paying Liquidated Damages; provided, however, that in the event the disclosure relates to a previously undisclosed proposed or pending material business transaction,
the disclosure of which the Company determines in good faith would be reasonably likely to impede the Company's ability to consummate such transaction, the Company may extend a Deferral Period from
45 days to 60 days without paying Liquidated Damages; provided further, however, that Deferral Periods may not total more than 90 days in the aggregate in any twelve-month period.
The Company 


5





 



shall
not be required to specify in the written notice to the Holders the nature of the event giving rise to the Deferral Period. 


        (c)   So
long as Notes remain outstanding, the Company shall notify the Trustee within five Business Days after each and every date on which an event occurs in respect of
which Liquidated Damages are required to be paid. Any amounts of Liquidated Damages due pursuant to clause (a)(i), (a)(ii) or (a)(iii) of this Section 3 will be payable in
cash semi-annually on each March 8 and September 8 (each, a "Damages Payment Date"), commencing with the first such date
occurring after any such Liquidated Damages commences to accrue, to Holders to whom regular interest is payable on such Damages Payment Date, with respect to Notes that are Registrable Securities, and
to Persons that are registered Holders on February 22 or August 24 immediately prior to a Damages Payment Date with respect to Underlying Shares that are Registrable Securities. The
amount of Liquidated Damages for Registrable Securities will be determined by multiplying the applicable rate of Liquidated Damages by the Amount of Registrable Securities outstanding on the Damages
Payment Date following such Registration Default in the case of the first such payment of Liquidated Damages with respect to a Registration Default (and thereafter at the next succeeding Damages
Payment Date until the cure of such Registration Default), multiplied by a fraction, the numerator of which is the number of days such Liquidated Damages rate was applicable during such period
(determined on the basis of a 360-day year comprised 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. 


4.    Registration Procedures. 


        In
connection with the filing of any Registration Statement pursuant to Section 2 hereof, the Company 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 Company hereunder the Company
shall: 


        (a)   Prepare
and file with the SEC, on or prior to the Filing Date, a Registration Statement or Registration Statements as prescribed by Section 2 hereof, and use all
reasonable efforts to cause each such Registration Statement to become effective and remain effective as provided herein; provided, however, that before filing any Registration Statement or Prospectus
or any amendments or supplements thereto, the Company shall furnish to and afford the Holders of the Registrable Securities covered by such Registration Statement a reasonable opportunity to review
copies of all such documents proposed to be filed (in each case, where possible, at least three Business Days prior to such filing, or such later date as is reasonable under the circumstances). The
Company shall not file any Registration Statement or Prospectus or any amendments or supplements thereto if the Holders of a majority in Amount of Registrable Securities covered by such Registration
Statement shall reasonably object in writing within such period. 


6







   
        (b)   Prepare and file with the SEC such amendments and post-effective amendments to each Shelf Registration, as may be necessary to keep such Registration
Statement continuously effective for the Effectiveness Period; 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 Registrable Securities covered by such Registration Statement as so amended or in such Prospectus as so supplemented. The Company shall be deemed not to
have used all reasonable efforts to keep a Registration Statement effective during the Effectiveness Period if it voluntarily takes any action that would result in Selling Holders of the Registrable
Securities covered thereby not being able to sell such Registrable Securities during that period unless such action is required by applicable law or unless the Company is acting in compliance with
this Agreement, including without limitation the provisions of Section 4(i) hereof. 


        (c)   Notify
the Selling Holders and Designated Counsel, if any, promptly (but in any event within two Business Days), (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 Company, 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) 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 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 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 (iv) of the
Company's determination that a post-effective amendment to a Registration Statement would be appropriate. 


        (d)   Use
all 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 and, if any such order is issued, to use all reasonable efforts to obtain the withdrawal of any such order at the earliest possible moment, and provide immediate notice to the Selling
Holders of the withdrawal of any such order. 


        (e)   Furnish
via e-mail to each Selling Holder and Designated Counsel, if any, at the sole expense of the Company, 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. 


        (f)    Deliver
to each Selling Holder and Designated Counsel, if any, at the sole expense of the Company, as many copies of the Prospectus (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, provided, however, that no more than 75 copies of each
such document need be delivered to any such Person; and, subject to the second paragraph of Section 4(q) hereof, the Company hereby consents to the use of such Prospectus and each amendment or
supplement thereto by each of the Selling Holders of Registrable Securities and dealers, if any, in 


7





 



connection
with the offering and sale of the Registrable Securities covered by such Prospectus and any amendment or supplement thereto. 


        (g)   The
Company agrees to cause the Company's counsel to perform Blue Sky investigations and file registrations and qualifications required to be filed in connection with
the registration or qualification (or exemption from such registration or qualification) of such Registrable Securities or offer and sale under the securities or Blue Sky laws of such jurisdictions
within the United States as any Selling Holder reasonably requests, 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 under Blue Sky laws to enable the disposition in such jurisdictions of the Registrable
Securities covered by the applicable Registration Statement; provided, however, that the Company shall not be required to (i) qualify generally to do business in any jurisdiction where it is
not then so qualified, (ii) take any action that would subject it to general service of process in any such jurisdiction where it is not then so subject or (iii) subject itself to
taxation in any such jurisdiction where it is not then so subject. 


        (h)   Cooperate
with the Selling Holders and their respective counsel to facilitate the timely preparation and delivery of certificates representing shares of Registrable
Securities to be sold, which certificates shall not bear any restrictive legends (after effectiveness of the Shelf Registration) and shall be in a form eligible for deposit with The Depository Trust
Company; and enable such shares of Registrable Securities to be in such denominations and registered in such names as the Selling Holders may reasonably request. 



        (i)    Upon
the occurrence of any event contemplated by Section 4(c)(ii), 4(c)(iii) or 4(c)(iv) hereof, as promptly as practicable prepare and (subject to
Section 4(a) hereof) file with the SEC, at the sole expense of the Company, 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, 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. 



        (j)    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 in a form eligible for deposit with The Depository Trust Company and (ii) provide a CUSIP number for the Registrable Securities. 


        (k)   Make
available at reasonable times for inspection by one or more representatives of the Selling Holders, designated in writing by Holders of a majority in Amount of
Registrable Securities to be included in such Registration Statement of such Registrable Securities being sold, and any attorney or accountant retained by any such Selling Holders (collectively, the
"Inspectors"), at the offices where normally kept, during reasonable business hours, at such time or times as shall be mutually convenient for the
Company and the Inspectors as a group, all financial and other records, pertinent corporate documents and instruments of the Company and its 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 Company and its subsidiaries to supply all information reasonably requested by any such Inspector in connection with such Registration Statement; provided, however, that such
inspections may not occur more than twice in any twelve-month period. Records that the Company determines, in good faith, to be confidential and any Records that it notifies the Inspectors are
confidential shall not be disclosed by any Inspector unless (i) the disclosure of such Records is necessary to avoid or correct a material misstatement or material omission in such Registration
Statement, (ii) the release of such Records is ordered pursuant to a subpoena or other 


8





 



order
from a court of competent jurisdiction or (iii) the information in such Records has been made generally available to the public other than through the acts of such Inspector; provided,
however, that prior notice shall be provided as soon as practicable, and in no event less than ten (10) Business Days prior to the potential disclosure, to the Company of the potential
disclosure of any information by such Inspector pursuant to clause (ii) of this sentence to permit the Company to obtain a protective order (or waive the provisions of this
paragraph (k)). Each Inspector shall take such actions as are reasonably necessary to protect the confidentiality of such information (if practicable) to the extent such actions are otherwise
not inconsistent with, an impairment of or in derogation of the rights and interests of the Holder or any Inspector, unless and until such information in such Records has been made generally available
to the public other than as a result of a breach of this Agreement. 


        (l)    Provide
(i) the Holders of the Registrable Securities to be included in such Registration Statement and Designated Counsel, if any, (ii) the sales or
placement agent, if any, thereof, and (iii) one counsel for such agents, reasonable opportunity to participate in the preparation of such Registration Statement, each prospectus included
therein or filed with the SEC, and each amendment or supplement thereto. 


        (m)  Comply
with all applicable rules and regulations of the SEC and make generally available to its security holders 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) commencing on the first day of the first fiscal quarter of the Company
after the effective date of a Registration Statement, which statements shall cover said 12-month periods. 


        (n)   Cause
the Indenture to be qualified under the TIA not later than the effective date of the first Registration Statement relating to the Registrable Securities; and in
connection therewith, cooperate with the Trustee and the Holders of the Registrable Securities and their respective counsel to effect such changes to the Indenture as may be required for the Indenture
to be so qualified in accordance with the terms of the TIA; and execute, and use all reasonable efforts to cause the 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 the Indenture to be so qualified in a timely manner. 


        (o)   Use
all reasonable efforts to cause the Registrable Securities covered by any Shelf Registration Statement to be registered with or approved by such other governmental
agencies or authorities as may be reasonably necessary to enable the Selling Holder or Holders thereof 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 Company will cooperate in all reasonable respects with the filing of such Registration Statement and the granting of
such approvals. 


        (p)   If
requested by Designated Counsel, if any, or the Holders of the majority in Amount of Registrable Securities (i) promptly incorporate in a prospectus supplement
or post-effective amendment such information as the Designated Counsel, if any, or such Holders reasonably determine is necessary to be included therein, (ii) make all required
filings of such prospectus supplement or such post-effective amendment as soon as reasonably practicable after the Company has 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 Company shall not be
required to take any of the actions set forth in this subclause (p) in the event the Company has received the written advice of outside counsel that such action is not required by applicable
laws or regulations. 


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

        Each
Holder agrees, by acquisition of the Registrable Securities, that no Holder shall be entitled to sell any of such Registrable Securities pursuant to a Registration Statement or to
receive a Prospectus relating thereto, unless such Holder has furnished the Company with a Notice and Questionnaire as required pursuant to Section 2(d) hereof (including the information
required to be included in such Notice and Questionnaire) and the information set forth in the next sentence. Each Selling Holder agrees promptly to furnish to the Company all information required to
be disclosed in order to make the information previously furnished to the Company by such Selling Holder not misleading and any other information regarding such Selling Holder and the distribution of
such Registrable Securities as the Company may from time to time reasonably request. Any sale of any Registrable Securities by any Holder shall constitute a representation and warranty by such Holder
that the information relating to such Holder and its plan of distribution is as set forth in the Prospectus delivered by such Holder in connection with such disposition, that such Prospectus does not
as of the time of such sale contain any untrue statement of a material fact relating to or provided by such Holder or its plan of distribution and that such Prospectus does not as of the time of such
sale omit to state any material fact relating to or provided by such Holder or its plan of distribution necessary to make the statements in such Prospectus, in the light of the circumstances under
which they were made, not misleading. 


        The
Company may require each Selling Holder of Registrable Securities as to which any registration is being effected to furnish to the Company such additional information regarding such
Holder and the distribution of such Registrable Securities as the Company may, from time to time, reasonably request to the extent necessary or advisable to comply with the Securities Act. The Company
may exclude from such registration the Registrable Securities of any Selling Holder if such Holder fails to furnish such additional information within 20 Business Days after receiving such request.
Each Selling Holder as to which any Shelf Registration is being effected agrees to furnish promptly to the Company all information required to be disclosed so that the information previously furnished
to the Company by such Holder is not materially misleading and does not omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading in
light of the circumstances under which they were made. 


        Each
Holder of Registrable Securities agrees by acquisition of such Registrable Securities that, upon actual receipt of any notice from the Company of the Company suspending the
effectiveness of the Registration Statement pursuant to Section 3(b) hereof, or upon the happening of any event of the kind described in Section 4(c)(ii), 4(c)(iii) or
4(c)(iv) hereof, such Holder will forthwith discontinue disposition of such Registrable Securities covered by such Registration Statement or Prospectus until such Holder's receipt of the copies
of the supplemented or amended Prospectus contemplated by Section 4(i) hereof, or until it is advised in writing by the Company that the use of the applicable Prospectus may be resumed,
and has received copies of any amendments or supplements thereto. Each Holder agrees to keep any such notice in confidence. 


10







   
5.    Registration Expenses. 


        (a)   All
fees and expenses incident to the performance of or compliance with this Agreement by the Company shall be borne by the Company, including, without limitation,
(i) all registration and filing fees (including, without limitation, 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 Securities and determination of the eligibility of the Registrable Securities for investment under the laws of
such jurisdictions as provided in Section 4(g) hereof), (ii) printing expenses, including, without limitation, expenses of printing certificates for Registrable Securities in a form
eligible for deposit with The Depository Trust Company and of printing prospectuses if the printing of prospectuses is requested by the Holders of the majority in Amount of Registrable Securities
included in any Registration Statement, (iii) messenger, telephone and delivery expenses, (iv) fees and disbursements of counsel for the Company, (v) Securities Act liability
insurance, if the Company desires such insurance, (vi) fees and expenses of all other Persons retained by the Company, (vii) internal expenses of the Company (including, without
limitation, all salaries and expenses of officers and employees of the Company performing legal or accounting duties), (viii) the expense of any annual audit, (ix) the fees and expenses
incurred in connection with the listing of the securities to be registered on any securities exchange, if applicable, and (x) the expenses relating to printing, word processing and distributing
all Registration Statements and any other documents necessary in order to comply with this Agreement. Notwithstanding anything in this Agreement to the contrary, each Holder shall pay all brokerage
commissions with respect to any Registrable Securities sold by it and, except as set forth in Section 5(b) below the Company shall not be responsible for the fees and expenses of any counsel,
accountant or advisor for the Holders. 


        (b)   The
Company shall reimburse the Holders of the Registrable Securities being registered in a Shelf Registration for the reasonable fees and disbursements, of Designated
Counsel; provided, however, that in no event shall the Company be required to pay more than $10,000 in the aggregate with respect to such fees and disbursements. 


6.    Indemnification. 


        The
Company agrees to indemnify and hold harmless (a) each Holder (which, for the absence of doubt, for purposes of this Section 6 shall include the Initial Purchasers),
(b) each Person, if any, who controls (within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act) any Holder (any of the Persons referred to
in this clause (b) being hereinafter referred to as a "Controlling Person"), (iii) the respective officers, directors, partners,
employees, representatives and agents of any Holder or any controlling person (any person referred to in clause (a), (b) or (c) may hereinafter be referred to as an
"Indemnified Holder"), against any losses, claims, damages or liabilities to which such Indemnified Holder may become subject under the Securities Act
or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue
statement of any material fact contained in any Registration Statement or Prospectus, or any amendment or supplement thereto or any related preliminary prospectus or (ii) the omission or
alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in the light of the circumstances in which they were made;
provided, however, that the Company will not be liable under this paragraph, (x) to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement
or alleged untrue statement, or omission or alleged omission made in any such Registration Statement or Prospectus, or any amendment or supplement thereto or any related preliminary prospectus in
reliance upon and in conformity with written information relating to any Holder furnished to the Company by or on behalf of such Holder specifically for use therein or (y) with respect to any
untrue statement or alleged untrue statement, or omission or alleged omission made in any preliminary prospectus if the person asserting any such loss, claim, damage or liability who purchased
Registrable Securities which are the subject thereof did not receive a copy of the Prospectus 


11





 



(or
of the preliminary prospectus as then amended or supplemented if the Company shall have furnished such Indemnified Holder with such amendment or supplement thereto on a timely basis) at or prior
to the written confirmation of the sale of such Registrable Securities to such person and, in any case where such delivery is required by applicable law and the untrue statement or alleged untrue
statement or omission or alleged omission of a material fact made in such preliminary prospectus was corrected in the Prospectus (or the preliminary prospectus as then amended or supplemented if the
Company shall have furnished such Indemnified Holder with such amendment or supplement thereto on a timely basis). The Company shall notify such Indemnified Holder promptly of the institution, threat
or assertion of any claim, proceeding (including any governmental investigation) or litigation in connection with the matters addressed by this Agreement that involves the Company or such Indemnified
Holder. 


        The
Company agrees to reimburse each Indemnified Holder promptly after demand for any legal or other out-of-pocket expenses reasonably incurred by such
Indemnified Holder in connection with investigating or defending any such loss, claim, damage or liability, any action or proceeding or in responding to a subpoena or governmental inquiry related to
the offering of the Registrable Securities, whether or not such Indemnified Holder is a party to any action or proceeding. In the event that it is finally judicially determined that an Indemnified
Holder was not entitled to receive payments for legal and other expenses pursuant to this paragraph, such Indemnified Holder will promptly return all sums that had been advanced pursuant hereto. 


        Each
Holder agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, officers, partners, employees, representatives and agents, and each Person who
controls the Company (within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act) to the same extent as the indemnity provided in the first paragraph
of this Section 6 from the Company to each Holder, but only with reference to such losses, claims, damages or liabilities which 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 a Holder furnished to the Company in writing by such Holder expressly for use in any Registration Statement
or Prospectus, or any amendment or supplement thereto or any related preliminary prospectus. The liability of any Holder under this paragraph shall in no event exceed the proceeds received by such
Holder from sales of Registrable Securities giving rise to such obligation. 


        In
case 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 first and third paragraphs of this Section 6, such Person (the "Indemnified Person") shall
promptly notify the Person or Persons against whom such indemnity may be sought (each an "Indemnifying Person") in writing. No indemnification provided
for in the first or third paragraphs of this Section 6 shall be available to any Person who shall have failed to give notice as provided in this paragraph if the party to whom notice was not
given was unaware of the proceeding to which such notice would have related and was materially prejudiced by the failure to give such notice, but the failure to give such notice shall not relieve the
Indemnifying Person or Persons from any liability which it or they may have to the Indemnified Person for contribution or otherwise than on account of the provisions of the first and third paragraphs
of this Section 6. In case any such proceeding shall be brought against any Indemnified Person and it shall notify the Indemnifying Person of the commencement thereof, the Indemnifying Person
shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other Indemnifying Person similarly notified, to assume the defense thereof, with counsel reasonably
satisfactory to such Indemnified Person and shall pay as incurred (or within 30 days of presentation) the fees and disbursements reasonably incurred by such counsel related to such proceeding.
In any such proceeding, any Indemnified Person shall have the right to retain its own counsel at its own expense. Notwithstanding the foregoing, the Indemnifying Person shall pay as incurred (or
within 30 days of presentation) the fees and expenses reasonably 


12





 



incurred
by the counsel retained by the Indemnified Person in the event (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the retention of such counsel,
(ii) the named parties to 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 or (iii) the Indemnifying Person shall have failed to assume the defense and employ counsel reasonably
acceptable to the Indemnified Person within a reasonable period of time after notice of commencement of the action. It is understood that the Indemnifying Person shall not, in connection with any
proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm for all such Indemnified Persons. Such firm shall be
designated in writing by Holders of a majority in Amount of Registrable Securities in the case of parties indemnified pursuant to the first paragraph of this Section 6 and by the Company in the
case of parties indemnified pursuant to the third paragraph of this Section 6. 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 judgment for the plaintiff, the Indemnifying Person agrees to indemnify the Indemnified Person from and against any loss or
liability by reason of such settlement or judgment. In addition, the Indemnifying Person will not, without the prior written consent of the Indemnified Person, settle or compromise or consent to the
entry of any judgment in any pending or threatened claim, action or proceeding of which indemnification may be sought hereunder (whether or not any Indemnified Person is an actual or potential party
to such claim, action or proceeding) unless such settlement, compromise or consent includes an unconditional release of each Indemnified Person from all liability arising out of such claim, action or
proceeding. 


        To
the extent the indemnification provided for in this Section 6 is unavailable to or sufficient to hold harmless an Indemnified Person under the first or third paragraph of this
Section 6 in respect of any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to therein, except by reason of the exceptions set forth in the first
or third paragraphs of this Section 6 or the failure of the Indemnified Person to give notice as required in the fourth paragraph of this Section 6,
then each Indemnifying Person shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (or actions or proceedings in respect
thereof) in such proportion as is appropriate to reflect the relative benefits received by the Indemnifying Person on the one hand and the Indemnified Person on the other hand from the offering of the
Notes pursuant to the Purchase Agreement and the Registrable Securities pursuant to any Shelf Registration. If, however, the allocation provided by the immediately preceding sentence is not permitted
by applicable law then each Indemnifying Person shall contribute to such amount paid or payable by such Indemnified Person in such proportion as is appropriate to reflect not only such relative
benefits but also the relative fault of the Indemnifying Person on the one hand and the Indemnified Person on the other in connection with the statements or omissions which resulted in such losses,
claims, damages or liabilities (or actions or proceedings in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and
any Indemnified Holder on the other shall be deemed to be in the same proportion as the total net proceeds (before deducting expenses) received by the Company from the offering and sale of the Notes
bear to the total net proceeds received by such Indemnified Holder from sales of Registrable Securities giving rise to such obligations. The relative fault 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 Company on the one
hand or such Indemnified Holder on the other and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. 



        The
Company and the Initial Purchasers agree that it would not be just and equitable if contributions pursuant to the immediately preceding paragraph of this Section 6 were
determined by pro rata allocation or by any other method of allocation which does not take account of the equitable 


13





 



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 or liabilities (or actions or
proceedings in respect thereof) referred to in the immediately preceding paragraph shall be deemed to include any non-reimbursed legal or other expenses reasonably incurred by such
Indemnified Person in connection with investigating or defending any such action or claim or enforcing any rights hereunder. Notwithstanding the provisions of this paragraph and the immediately
preceding paragraph of this Section 6, (i) in no event shall any Holder be required to contribute any amount in excess of the amount by which the net proceeds received by such Holder
from the offering or sale of the Registrable Securities pursuant to a Shelf Registration Statement exceeds the amount of damages which such Holder would have otherwise been required to pay by reason
of such untrue or alleged untrue statement or omission or alleged omission and (ii) 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. 



        Except
as otherwise provided in this Section 6, any losses, claims, damages, liabilities or expenses for which an Indemnified Person is entitled to indemnification or contribution
under this Section 6 shall be paid by the Indemnifying Person to the Indemnified Person as such losses, claims, damages, liabilities or expenses are incurred (or within 30 days of
presentation). 


        The
remedies provided for in this Section 6 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any indemnified party at law or in
equity. 


        The
indemnity and contribution agreements contained in this Section 6 shall remain operative and in full force and effect regardless of (i) any termination of this
Agreement, (ii) any investigation made by or on behalf of any Holder or any Person controlling any Holder or by or on behalf of the Company, its officers or directors or any other Person
controlling any of the Company and (iii) acceptance of and payment for any of the Registrable Securities. 


7.    Rules 144 and 144A. 


        The
Company covenants that 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, for so long as any Registrable Securities remain outstanding, if at any time the Company is not
required to file such reports, it will, upon the request of any Holder or beneficial owner of Registrable Securities, make available such information necessary to permit sales pursuant to
Rule 144A under the Securities Act. The Company further covenants that, for so long as any Registrable Securities remain outstanding, it will use all reasonable efforts to take such further
action as any Holder of Registrable Securities may reasonably request, all to the extent required from time to time to enable such holder to sell Registrable Securities without registration under the
Securities Act within the limitation of the exemptions provided by (a) Rule 144 and Rule 144A under the Securities Act, as such rules may be amended from time to time, or
(b) any similar rule or regulation hereafter adopted by the SEC. The Company will provide a copy of this Agreement to prospective purchasers of Registrable Securities identified to the Company
by the Initial Purchasers upon request in writing. Upon the request of any Holder, the Company shall deliver to such Holder a written statement as to whether it has complied with such requirements.
Notwithstanding the foregoing, nothing in this Section 7 shall be deemed to require the Company to register any of its securities pursuant to the Exchange Act or list its securities on any
exchange other than PORTAL or Nasdaq. 


8.    Underwritten Registrations. 


        No
Holder of Registrable Securities may participate in any Underwritten Registration hereunder. 


14





 



9.    Miscellaneous. 


        (a)   No Inconsistent Agreements. The Company has not, as of the date hereof, and the Company shall not, after the date of this
Agreement, enter into any agreement with respect to any of its securities that is inconsistent with the rights granted to the Holders of Registrable Securities in this Agreement or otherwise conflicts
with the provisions hereof. 


        (b)   Adjustments Affecting Registrable Securities. The Company 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 Company and the Holders of not less than the majority in Amount of Registrable
Securities; provided, however, that Section 6 and this Section 9(c) may not be amended, modified or supplemented without the prior written consent of the Company and each Holder
(including, in the case of an amendment, modification or supplement of Section 6, any Person who was a Holder of Registrable Securities disposed of pursuant to any Registration Statement).
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 principal amount of the Registrable Securities being sold by such Holders pursuant to such Registration Statement. 



        (d)   Notices. All notices and other communications (including without limitation any notices or other communications to the
Trustee) provided for or permitted hereunder shall be made in writing by hand-delivery, registered first-class mail, next-day air courier or facsimile:

and Questionnaire or any amendment thereto, in which case such information shall control.

        (e)   Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors and assigns of

in Amount of Registrable Securities is required hereunder, Registrable Securities held by the Company or its 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. 



        (k)   Third-Party Beneficiaries. Holders of Registrable Securities are intended third party beneficiaries of this Agreement and
this Agreement may be enforced by such Persons. 


        (l)    Entire Agreement. This Agreement, together with the Purchase Agreement and the Indenture, is intended by the parties as a

REGISTRATION RIGHTS AGREEMENT
