    2.   SHELF REGISTRATION.

         (a)  SHELF REGISTRATION.  The Company shall prepare and file with 
the SEC, as soon as practicable but in any event on or prior to the date 
ninety (90) days following the latest date of original issuance of the Notes 
(the "Filing Date"), a Registration Statement for an offering to be made on a 
continuous basis pursuant to Rule 415 of the Securities Act (a "Shelf 
Registration") registering the resale from time to time by Holders thereof of 
all of the Registrable Securities (the "Initial Shelf Registration").  The 
Initial Shelf Registration shall be on Form S-3 or another appropriate form 
permitting registration of such Registrable Securities for resale by such 
Holders in the manner or manners designated by them (including, without 
limitation, one or more Underwritten Offerings).  Each Holder who first 
becomes a Holder prior to the Filing Date may include its Registrable 
Securities in the Shelf Registration by obtaining from the Trustee or the 
Company a selling securityholder questionnaire in such form provided by the 
Company (a "Selling Securityholder Questionnaire") and, not later than 10 
days prior to the Filing Date, returning to the Company a duly completed 
Selling Securityholder Questionnaire (a) providing such information with 
respect to such Holder and its Registrable Securities required to be included 
in the Shelf Registration (the "Requisite Information") and (b) agreeing to 
be named as a Selling Securityholder therein in accordance with the terms 
hereof.  Failure of any Holder to return a completed Selling Securityholder 
Questionnaire prior to the Filing Date shall not affect such Holder's rights 
under Section 2(d) hereof.  The Company shall use its reasonable efforts to 
cause the Initial Shelf Registration to be declared effective under the 
Securities Act as soon as practicable and, in any event, within one hundred 
and eighty (180 )days following the latest date of original issuance of the 
Notes and to keep the Initial Shelf Registration effective under the 
Securities Act until the earlier of the expiration of the Effectiveness 
Period or the date a Subsequent Shelf Registration, as defined below, 
covering all of the Registrable Securities has been declared effective under 
the Securities Act.

         (b)  If the Initial Shelf Registration or any Subsequent Shelf 
Registration, as 

                                      4.


defined below, ceases to be effective for any reason as a result of the 
issuance of a stop order by the SEC at any time during the Effectiveness 
Period, the Company shall use its reasonable efforts to obtain the prompt 
withdrawal of any order suspending the effectiveness thereof, and in any 
event shall within thirty (30) days of such cessation of effectiveness amend 
the Shelf Registration in a manner reasonably expected to obtain the 
withdrawal of the order suspending the effectiveness thereof, or file an 
additional Shelf Registration covering all of the then Registrable Securities 
(a "Subsequent Shelf Registration").  If a Subsequent Shelf Registration is 
filed, the Company shall use its reasonable efforts to cause the Subsequent 
Shelf Registration to be declared effective as soon as practicable after such 
filing and to keep such Registration Statement continuously effective until 
the end of the Effectiveness Period.

         (c)  The Company shall supplement and amend the Shelf Registration 
if required by the rules, regulations or instructions applicable to the 
registration form used by the Company for such Shelf Registration, if 
required by the Securities Act, or if reasonably requested by the Initial 
Purchasers or by the Trustee on behalf of a majority of the Holders of the 
Registrable Securities covered by such Registration Statement or by any 
Managing Underwriter of such Registrable Securities in the event of an 
Underwritten Offering of the Registrable Securities.

         (d)  Each Holder of Registrable Securities agrees that if such 
Holder wishes to sell its Registrable Securities pursuant to a Shelf 
Registration and related Prospectus, it will do so only in accordance with 
this Section 2(d).  To effect a sale of Registrable Securities pursuant to a 
Shelf Registration, each Holder included in the Shelf Registration as a 
Selling Securityholder of Registrable Securities must, at least 10 Business 
Days prior to any intended distribution of Registrable Securities, deliver 
written notice to the Company specifying the date upon which the Holder 
intends to begin such distribution and providing any additional or modified 
Requisite Information or a statement that the Requisite Information 
previously provided remains true and correct as of the date of such notice.  
A Holder of Registrable Securities not included in the Shelf Registration 
that wishes to have its Registrable Securities included in a Shelf 
Registration must, simultaneously with or prior to delivery of the notice 
specified in the preceding sentence, obtain a Selling Securityholder 
Questionnaire from the Trustee or the Company and deliver to the Company a 
completed Selling Securityholder Questionnaire (a) providing Requisite 
Information and (b) agreeing to be named as a Selling Securityholder in the 
Shelf Registration in accordance with the terms hereof.  Each Holder may 
deliver a maximum of three (3) notices pursuant to this Section 2(d) in any 
12-month period.  As soon as practicable after the date such notice is 
provided, and in any event within five Business Days after such date, the 
Company shall either:

              (i)  (A) If necessary, prepare and file with the Commission a 
post-effective amendment to the Shelf Registration or 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 such 
Registration Statement 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 not misleading, and so that, as 
thereafter delivered to purchasers of the Registrable Securities being sold 
thereunder, such Prospectus will not contain an untrue 

                                      5.


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 light of the 
circumstances under which they were made, not misleading; (B) provide the 
Notice Holders (as defined below) copies of any documents filed pursuant to 
Section 2(d)(i)(A); and (C) inform the Notice Holders that the Company has 
complied with its obligations in Section 2(d)(i)(A) (or that, if the Company 
has filed a post-effective amendment to the Shelf Registration which has not 
yet been declared effective, the Company will notify the Notice Holders to 
that effect, will use its reasonable efforts to secure the effectiveness of 
such post-effective amendment and will immediately notify the Notice Holders 
when the amendment has become effective); each Holder who has given notice of 
intention to distribute such Holder's Registrable Securities in accordance 
with Section 2(d) hereof (a "Notice Holder") will sell all or any of such 
Registrable Securities pursuant to the Shelf Registration and related 
Prospectus only during the 30-day period commencing with the date on which 
the Company gives notice, pursuant to Section 2(d)(i)(C), that the 
Registration Statement and Prospectus may be used for such purpose (such 
30-day period is referred to as a "Selling Period").  The Notice Holders will 
not sell any Registrable Securities pursuant to such Registration Statement 
or Prospectus after such Selling Period without giving a new notice of 
intention to sell pursuant to Section 2(d) hereof and receiving a further 
notice from the Company pursuant to Section 2(d)(i)(C) hereof.

              (ii) in the event (A) of the happening of any event of the kind 
described in Section 3(c)(ii), 3(c)(iii), 3(c)(iv), 3(c)(v) or 3(c)(vi) 
hereof or (B) that, in the judgment of the Company, it is advisable to 
suspend use of the Prospectus for a discrete period of time due to pending 
material corporate developments or similar material events that have not yet 
been publicly disclosed and as to which the Company believes public 
disclosure will be prejudicial to the Company, the Company shall deliver a 
certificate in writing, signed by an authorized executive officer of the 
Company, to the Notice Holders, the Special Counsel and the Managing 
Underwriters, if any, to the effect of the foregoing and, upon receipt of 
such certificate, each such Notice Holder's Selling Period will not commence 
or, if commenced, will be suspended, until such Notice Holder's receipt of 
copies of the supplemented or amended Prospectus provided for in Section 
2(d)(i)(A) hereof, or until it is advised in writing by the Company that the 
Prospectus may be used, and has received copies of any additional or 
supplemental filings that are incorporated or deemed incorporated by 
reference in such Prospectus.  The Company will use its reasonable efforts to 
ensure that the use of the Prospectus may be resumed, and the Selling Period 
will commence, as soon as practicable and, in the case of a pending 
development or event referred to in Section 2(d)(ii)(B) hereof, as soon as 
practicable following public disclosure of such pending material corporate 
development or similar material event. Notwithstanding the foregoing, (A) the 
Company shall not under any circumstances be entitled to exercise its right 
under this Section 2(d)(ii) to defer the commencement of a Selling Period 
more than one (1) time in any three (3) month period and the period in which 
a Selling Period is suspended shall not exceed fifteen (15) days unless the 
Company shall deliver to such Notice Holders a second notice to the effect 
set forth above, which shall have the effect of extending the period during 
which such Selling Period is deferred or suspended by up to an additional 
fifteen (15) days, or such shorter period of time as is specified in such 
second notice, and (B) in no event shall the Company be permitted to extend 


                                      6.


the period during which such Selling Period is deferred from and after the 
date a Notice Holder provides notice to the Company in accordance with this 
Section 2(d) of its intention to distribute Registrable Securities (a 
"Deferral Period") beyond such thirty (30) day period, PROVIDED, that the 
Company may suspend the use of such Prospectus for longer periods so long as 
the Company complies with its obligations, if any, to pay Liquidated Damages 
in accordance with Section 2(e) hereof.

         (e)  The parties hereto agree that the Holders of Registrable 
Securities will suffer damages, and that it would not be feasible to 
ascertain the extent of such damages with precision, if (i) the Initial Shelf 
Registration has not been filed on or prior to the Filing Date (unless the 
delay in filing is caused by failure of Holders to provide Requisite 
Information and agree to be named as Selling Securityholders in the Shelf 
Registration or by objections received pursuant to Section 3(a) hereof), (ii) 
prior to the end of the Effectiveness Period, the SEC shall have issued a 
stop order suspending the effectiveness of the Shelf Registration or 
proceedings have been initiated with respect to the Shelf Registration under 
Section 8(d) or 8(e) of the Securities Act, (iii) the aggregate number of 
days in any one Deferral Period exceeds the periods permitted pursuant to 
Section 2(d)(ii) hereof or (iv) the number of Deferral Periods exceeds the 
number permitted pursuant to Section 2(d)(ii) hereof (each of the events of a 
type described in any of the foregoing clauses (i) through (iv) are 
individually referred to herein as an "Event," and the Filing Date in the 
case of clause (i), the date on which the effectiveness of the Shelf 
Registration has been suspended or proceedings with respect to the Shelf 
Registration under Section 8(d) or 8(e) of the Securities Act have been 
commenced in the case of clause (ii), the date on which the duration of a 
Deferral Period exceeds the periods permitted by Section 2(d)(ii) hereof in 
the case of clause (iii), and the date of the commencement of a Deferral 
Period that causes the limit on the number of Deferral Periods under Section 
2(d)(ii) hereof to be exceeded in the case of clause (iv), being referred to 
herein as an "Event Date").  Events shall be deemed to continue until the 
date of the termination of such Event, which shall be the following dates 
with respect to the respective types of Events: the date the Initial 
Registration Statement is filed in the case of an Event of the type described 
in clause (i), the date that all stop orders suspending effectiveness of the 
Shelf Registration have been removed and the proceedings initiated with 
respect to the Shelf Registration under Section 8(d) or 8(e) of the 
Securities Act have terminated, as the case may be, in the case of Events of 
the types described in clause (ii), termination of the Deferral Period which 
caused the aggregate number of days in any one Deferral Period to exceed the 
number permitted by Section 2(d)(ii) to be exceeded in the case of Events of 
the type described in clause (iii), and termination of the Deferral Period 
the commencement of which caused the number of Deferral Periods permitted by 
Section 2(d)(ii) to be exceeded in the case of Events of the type described 
in clause (iv).

    Accordingly, upon the occurrence of any Event and until such time as 
there are no Events which have occurred and are continuing (a "Damages 
Accrual Period"), commencing on the Event Date on which such Damages Accrual 
Period began, the Company agrees to pay, as liquidated damages, and not as a 
penalty, an additional amount (the "Liquidated Damages"): (A)(i) to each 
holder of a Note that is a Notice Holder, accruing at a rate equal to 
one-quarter of one percent per annum (25 basis points) on the aggregate 
principal amount of Notes held by such 


                                      7.


Notice Holder and (ii) to each holder of Common Stock that is a Notice 
Holder, accruing at a rate equal to one-quarter of one percent per annum (25 
basis points) calculated on an amount equal to the product of (x) the 
then-applicable Conversion Price (as defined in the Indenture), times (y) the 
number of shares of Common Stock held by such holder; and (B) if the Damages 
Accrual Period continues for a period in excess of thirty (30) days from the 
Event Date, from and after the end of such thirty (30) days until such time 
as there are no Events which have occurred and are continuing, (i) to each 
holder of a Note (whether or not a Notice Holder), accruing at a rate equal 
to one-quarter of one percent per annum (25 basis points) on the aggregate 
principal amount of Notes held by such holder and (ii) to each holder of 
Common Stock (whether or not a Notice Holder), accruing at a rate equal to 
one-quarter of one percent per annum (25 basis points) calculated on an 
amount equal to the product of (x) the then-applicable Conversion Price (as 
defined in the Indenture), times (y) the number of shares of Common Stock 
held by such holder. Notwithstanding the foregoing, no Liquidated Damages 
shall accrue under clause (A) for the preceding sentence during any period 
for which Liquidated Damages accrue under clause (B) of the preceding  
sentence or as to any Registrable Securities from and after the earlier of 
(x) the date such securities are no longer Registrable Securities, and (y) 
the expiration of the Effectiveness Period.  The rate of accrual of the 
Liquidated Damages with respect to any period shall not exceed the rate 
provided for in this paragraph notwithstanding the occurrence of multiple 
concurrent Events.

    The Company shall pay the Liquidated Damages due on any Notes or Common 
Stock by depositing with the Trustee under the Indenture, in trust, for the 
benefit of the holders of Notes or Common Stock or Notice Holder, as the case 
may be, entitled thereto, on or prior to the applicable Damages Payment Date, 
sums sufficient to pay the Liquidated Damages accrued or accruing since the 
last preceding Damages Payment Date through such Damages Payment Date.  The 
Liquidated Damages shall be paid by the Company  to the Record Holders on 
each Damages Payment Date by wire transfer of immediately available funds to 
the accounts specified by them or by mailing checks to their registered 
addresses as they appear in the Note register (as defined in the Indenture), 
in the case of the Notes, and in the register of the Company for the Common 
Stock, in the case of the Common Stock, if no such accounts have been 
specified on or before the Damage Payment Date; PROVIDED, HOWEVER, that any 
Liquidated Damages accrued with respect to any Note or portion thereof called 
for redemption on a redemption date, redeemed or repurchased in connection 
with a Fundamental Change (as defined in the Indenture) on a repurchase date, 
or converted into Common Stock on a conversion date prior to the Damages 
Payment Date, shall, in any such event, be paid instead to the holder who 
submitted such Note or portion thereof for redemption, repurchase or 
conversion on the applicable redemption date, repurchase date or conversion 
date, as the case may be, on such date (or promptly following the conversion 
date, in the case of conversion of a Note). The Trustee shall be entitled, on 
behalf of the holders of Notes, Common Stock and Notice Holder, to seek any 
available remedy for the enforcement of this Agreement, including for the 
payment of such Liquidated Damages. Notwithstanding the foregoing, the 
parties agree that the sole damages payable for a violation of the terms of 
this Agreement with respect to which Liquidated Damages are expressly 
provided shall be such Liquidated Damages.  Nothing shall preclude a Notice 
Holder or holder of Registrable Securities from pursuing or obtaining 
specific performance or other equitable relief 


                                      8.


with respect to this Agreement.

    All of the Company's obligations set forth in this Section 2(e) which are 
outstanding with respect to any Registrable Securities at the time such 
security ceases to be a Registrable Security shall cease to accrue at such 
time such security ceases to be a Registrable Security but shall survive 
until such time as all such obligations with respect to such security have 
been satisfied in full (notwithstanding termination of the Agreement pursuant 
to Section 8(o)).

    The parties hereto agree that the Liquidated Damages provided for in this 
Section 2(e) constitute a reasonable estimate of the damages that may be 
incurred by holders of Registrable Securities (other than the Initial 
Purchasers) by reason of the failure of the Shelf Registration to be filed or 
declared effective or unavailable (absolutely or as a practical matter) for 
effecting resales of Registrable Securities, as the case may be, in 
accordance with the provisions hereof.

    3.   REGISTRATION PROCEDURES.  In connection with the Company's 
registration obligations under Section 2 hereof, the Company shall effect 
such registrations to permit the sale of the Registrable Securities in 
accordance with the intended method or methods of disposition thereof, and 
pursuant thereto the Company shall as expeditiously as possible:

         (a)  Prepare and file with the SEC a Registration Statement or 
Registration Statements on any appropriate form under the Securities Act 
available for the sale of the Registrable Securities by the Holders thereof 
in accordance with the intended method or methods of distribution thereof, 
and use its reasonable efforts to cause each such Registration Statement to 
become effective and remain effective as provided herein; PROVIDED, that 
before filing any such Registration Statement or Prospectus or any amendments 
or supplements thereto (other than documents that would be incorporated or 
deemed to be incorporated therein by reference and that the Company is 
required by applicable securities laws or stock exchange requirements to 
file) the Company shall furnish to the Manager, the Special Counsel and the 
Managing Underwriters of such offering, if any, copies of all such documents 
proposed to be filed, which documents will be subject to the review of the 
Manager, the Special Counsel and such Managing Underwriters, and the Company 
shall not file any such Registration Statement or amendment thereto or any 
Prospectus or any supplement thereto (other than such documents which, upon 
filing, would be incorporated or deemed to be incorporated by reference 
therein and that the Company is required by applicable securities laws or 
stock exchange requirements to file) to which the Holders of a majority of 
the Registrable Securities covered by such Registration Statement, the 
Initial Purchasers or the Special Counsel shall reasonably object in writing 
within two full Business Days.

         (b)  Prepare and file with the SEC such amendments and 
post-effective amendments to each Registration Statement as may be necessary 
to keep such Registration Statement continuously effective for the applicable 
period specified in Section 2; cause the related Prospectus to be 
supplemented by any required Prospectus supplement, and as so supplemented to 
be filed pursuant to Rule 424 (or any similar provisions then in force) under 
the Securities Act; and comply with the provisions of the Securities Act with 
respect to the disposition of all 


                                      9.


securities covered by such Registration Statement during the applicable 
period in accordance with the intended methods of disposition by the sellers 
thereof set forth in such Registration Statement as so amended or such 
Prospectus as so supplemented.

         (c)  Notify the Notice Holders, the Manager, the Special Counsel and 
the Managing Underwriters, if any, promptly, and (if requested by any such 
person) confirm such notice in writing, (i) when a Prospectus, any Prospectus 
supplement, a Registration Statement or a post-effective amendment to a 
Registration Statement has been filed with the SEC, and, with respect to a 
Registration Statement or any post-effective amendment, when the same has 
become effective, (ii) of any request by the SEC or any other federal or 
state governmental authority for amendments or supplements to a Registration 
Statement or related Prospectus or for additional information, (iii) of the 
issuance by the SEC or any other federal or state governmental authority of 
any stop order suspending the effectiveness of a Registration Statement or 
the initiation or threatening of any proceedings for that purpose, (iv) of 
the receipt by the Company of any notification with respect to the suspension 
of the qualification or exemption from qualification of any of the 
Registrable Securities for sale in any jurisdiction or the initiation or 
threatening of any proceeding for such purpose, (v) of the existence of any 
fact or happening of any event which makes any statement of a material fact 
in such Registration Statement or related Prospectus or any document 
incorporated or deemed to be incorporated therein by reference untrue or 
which would require the making of any changes in the Registration Statement 
or Prospectus in order 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 Company's determination that a 
post-effective amendment to a Registration Statement would be appropriate.

         (d)  Use its reasonable efforts to obtain the withdrawal of any 
order suspending the effectiveness of a Registration Statement, or the 
lifting of any suspension of the qualification (or exemption from 
qualification) of any of the Registrable Securities for sale in any 
jurisdiction, at the earliest possible moment.

         (e)  If reasonably requested by the Manager or the Managing 
Underwriters, if any, or the Holders of a majority of the Registrable 
Securities being sold, (i) promptly incorporate in a Prospectus supplement or 
post-effective amendment to a Registration Statement such information as the 
Manager, the Special Counsel, the Managing Underwriters, if any, or such 
Holders, in connection with any offering of Registrable Securities, agree 
should be included therein as required by applicable law, and (ii) make all 
required filings of such Prospectus supplement or such post-effective 
amendment as soon as practicable after the Company has received notification 
of the matters to be incorporated in such Prospectus supplement or 
post-effective amendment; PROVIDED, that the Company shall not be required to 
take any actions under this Section 3(e) that are not, in the reasonable 
opinion of counsel for the Company, in compliance with applicable law.


                                      10.


         (f)  Furnish to each selling Holder (if so requested), the Special 
Counsel and the Manager, and each Managing Underwriter, if any, without 
charge, at least one conformed copy of the Registration Statement or 
Statements and any amendment thereto, including financial statements but 
excluding schedules, all documents incorporated or deemed to be incorporated 
therein by reference and all exhibits (unless requested in writing by such 
selling Holder, counsel, the Manager or underwriter).

         (g)  Deliver to each selling Holder, the Special Counsel and the 
Manager and each Managing Underwriter, if any, in connection with any 
offering of Registrable Securities, without charge, as many copies of the 
Prospectus or Prospectuses relating to such Registrable Securities (including 
each preliminary prospectus) and any amendment or supplement thereto as such 
persons may reasonably request; and the Company hereby consents to the use of 
such Prospectus or each amendment or supplement thereto by each of the 
selling Holders of Registrable Securities and the Underwriters, if any, in 
connection with any offering and sale of the Registrable Securities covered 
by such Prospectus or any amendment or supplement thereto.

         (h)  Prior to any public offering of Registrable Securities, to 
register or qualify or cooperate with the selling Holders, the Managing 
Underwriters, if any, and the Special 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 or Managing Underwriter reasonably requests in writing; 
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 necessary or advisable 
to enable the disposition in such jurisdictions of the Registrable Securities 
covered by the applicable Registration Statement; PROVIDED, that the Company 
will not be required to (i) qualify generally to do business in any 
jurisdiction where it is not then so qualified or (ii) take any action that 
would subject it to general service of process in suits or to taxation in any 
such jurisdiction where it is not then so subject.

         (i)  Cause the Registrable Securities covered by the applicable 
Registration Statement to be registered with or approved by such other 
governmental agencies or authorities within the United States, except as may 
be required solely as a consequence of the nature of such selling Holder, in 
which case the Company will cooperate in all reasonable respects with the 
filing of such Registration Statement and the granting of such approvals, as 
may be necessary to enable the selling Holder or Holders thereof or the 
Managing Underwriters, if any, to consummate the disposition of such 
Registrable Securities.

         (j)  During any Selling Period (other than during a Deferral 
Period), immediately upon the existence of any fact or the occurrence of any 
event as a result of which a Registration Statement shall 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, 
or a Prospectus shall contain any untrue statement of a material fact or omit 
to state 


                                      11.


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, promptly prepare and file a post-effective amendment to 
each Registration Statement or a supplement to the related Prospectus or any 
document incorporated therein by reference or file any other required 
document (such as a Current Report on Form 8-K) that would be incorporated by 
reference into the Registration Statement so that the Registration Statement 
shall 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 so that the Prospectus will not 
contain any untrue statement of a material fact or omit to state any 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, as thereafter delivered to the 
purchasers of the Registrable Securities being sold thereunder, and, in the 
case of a post-effective amendment to a Registration Statement, use its 
reasonable efforts to cause it to become effective as soon as practicable.

         (k)  In the event of an Underwritten Offering, enter into such 
agreements and take all such other actions in connection therewith (including 
those reasonably requested by the Managing Underwriters, if any, or the 
Holders of a majority of the Registrable Securities being sold) in order to 
expedite or facilitate the disposition of such Registrable Securities and in 
such connection, whether or not an underwriting agreement is entered into, 
and if the registration is an underwritten registration, (i) make such 
representations and warranties, subject to the Company's ability to do so, to 
the Holders of such Registrable Securities and the underwriters with respect 
to the business of the Company and its subsidiaries, the Registration 
Statement, Prospectus and documents incorporated by reference or deemed 
incorporated by reference, if any, in each case, in form, substance and scope 
as are customarily made by issuers to underwriters in underwritten offerings 
and confirm the same if and when requested; (ii) use its reasonable efforts 
to obtain opinions of counsel to the Company and updates thereof (which 
counsel and opinions (in form, scope and substance) shall be reasonably 
satisfactory to the Managing Underwriters, if any, Special Counsel and the 
Holders of a majority of the Registrable Securities being sold) addressed to 
each of the underwriters covering the matters customarily covered in opinions 
requested in underwritten offerings and such other matters as may be 
reasonably requested by such Special Counsel and Managing Underwriters; (iii) 
use its reasonable efforts to obtain "cold comfort" letters and updates 
thereof from the independent certified public accountants of the Company 
(and, if necessary, any other certified public accountants of any subsidiary 
of the Company or any business acquired or to be acquired by the Company for 
which financial statements and financial data are, or are required to be, 
included in the Registration Statement), addressed to each of the Managing 
Underwriters, if any, such letters to be in customary form and covering 
matters of the type customarily covered in "cold comfort" letters in 
connection with Underwritten Offerings; and (iv) deliver such documents and 
certificates as may be reasonably requested by the Holders of a majority of 
the Registrable Securities being sold, the Special Counsel and the Managing 
Underwriters, if any, to evidence the continued validity of the 
representations and warranties of the Company and its subsidiaries made 
pursuant to clause (i) above and to evidence compliance with any customary 
conditions contained in the underwriting agreement or other agreement entered 
into by the Company.  The 


                                      12.


above shall be done at each closing under such underwriting or similar 
agreement as and to the extent required thereunder.

         (l)  If requested in connection with a disposition of Registrable 
Securities pursuant to a Registration Statement, make available for 
inspection by a representative of the Holders of Registrable Securities being 
sold, any Managing Underwriter participating in any disposition of 
Registrable Securities, if any, and any attorney or accountant retained by 
such selling holders or underwriter, financial and other records, pertinent 
corporate documents and properties of the Company and its subsidiaries, and 
cause the executive officers, directors and employees of the Company and its 
subsidiaries to supply all information reasonably requested by any such 
representative, Managing Underwriter, attorney or accountant in connection 
with such disposition; subject to reasonable assurances by each such person 
that such information will only be used in connection with matters relating 
to such Registration Statement, PROVIDED, HOWEVER, that such persons shall 
first agree in writing with the Company that any information that is 
reasonably and in good faith designated by the Company in writing as 
confidential at the time of delivery of such information shall be kept 
confidential by such persons, unless (i) disclosure of such information is 
required by court or administrative order or is necessary to respond to 
inquiries of regulatory authorities, (ii) disclosure of such information is 
required by law (including any disclosure requirements pursuant to Federal 
securities laws in connection with the filing of any Registration Statement 
or the use of any prospectus referred to in this Agreement), (iii) such 
information becomes generally available to the public other than as a result 
of a disclosure or failure to safeguard by any such person or (iv) such 
information becomes available to any such person from a source other than the 
Company and such source is not bound by a confidentiality agreement.

         (m)   Comply with all applicable rules and regulations of the SEC 
and make generally available to its securityholders earning statements (which 
need not be audited) 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 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 
Company commencing after the effective date of a Registration Statement, 
which statements shall cover said 12-month periods.

         (n)  Cooperate with the selling holders of Registrable Securities to 
facilitate the timely preparation and delivery of certificates representing 
Registrable Securities to be sold and not bearing any restrictive legends; 
and enable such Registrable Securities to be in such denominations and 
registered in such names as the holders may request.

         (o)  Provide the transfer agent for the Common Stock with printed 
certificates for the Registrable Securities which are in a form eligible for 
deposit with The Depository Trust Company.


                                      13.


         (p)  Cause all shares of Common Stock covered by the Registration 
Statement to be listed on each securities exchange or quotation system on 
which the Company's Common Stock is then listed no later than the date the 
Registration Statement is declared effective and, in connection therewith, to 
the extent applicable, to make such filings under the Exchange Act as may be 
required and to have such filings declared effective thereunder.

         (q)  Cooperate and assist in any filings required to be made with 
the National Association of Securities Dealers, Inc.

         (r)  Notwithstanding any provision of this Agreement to the 
contrary, the Company shall not be required to amend or supplement the Shelf 
Registration pursuant to the Agreement if (i) such amendment or supplement 
would require the Company to disclose a material financing, acquisition or 
corporate transaction and the Company shall have determined that such 
disclosure is not in the best interests of the Company and the holders of its 
outstanding Common Stock or (ii) the Company shall have determined in good 
faith that there is a valid business purpose or reason for suspending the use 
of the Prospectus included in such Shelf Registration in accordance herewith 
instead of making such amendment or supplement; PROVIDED, that in each such 
case the Company complies with its obligations, if any, to pay Liquidated 
Damages.  

    4.   HOLDER'S OBLIGATIONS.  Each Holder agrees, by acquisition of the 
Notes and Registrable Securities, that no Holder of Registrable Securities 
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 the Selling Securityholder 
Questionnaire required pursuant to Section 2(a) hereof and the notice 
required pursuant to Section 2(d) hereof and such other information regarding 
such Holder and the distribution of such Registrable Securities as may be 
required to be included in the Registration Statement or the Prospectus or as 
the Company may from time to time reasonably request.  The Company may 
exclude from such registration the Registrable Securities of any Holder who 
does not furnish such information provided above for so long as such 
information is not so furnished.  Each Holder of Registrable Securities as to 
which any Registration Statement is being effected 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 Holder not 
misleading.  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 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 such Holder or its plan of 
distribution necessary to make the statements in such Prospectus, in light of 
the circumstances under which they were made, not misleading.

    5.   REGISTRATION EXPENSES.  All fees and expenses incident to the 
Company's 


                                      14.


performance of or compliance with this Agreement shall be borne by the 
Company whether or not any of the Registration Statements become effective. 
Such fees and expenses shall include, without limitation, (i) all 
registration and filing fees (including, without limitation, fees and 
expenses (x) with respect to filings required to be made with the National 
Association of Securities Dealers, Inc. and (y) of compliance with federal 
securities or Blue Sky laws (including, without limitation, fees and 
disbursements of Special Counsel in connection with Blue Sky qualifications 
of the Registrable Securities in such jurisdictions as the Managing 
Underwriters, if any, or Holders of a majority of the Registrable Securities 
being sold may designate)), (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 Special 
Counsel or the holders of a majority of the Registrable Securities included 
in any Registration Statement), (iii) messenger, telephone and delivery 
expenses, (iv) reasonable fees and disbursements of counsel for the Company 
and the Special Counsel (not to exceed $5,000) in connection with the Shelf 
Registration (provided that the Company shall not be liable for the fees and 
expenses of more than one separate firm for all parties participating in any 
transaction hereunder), (v) fees and disbursements of all independent 
certified public accountants referred to in Section 3(k)(iii) hereof 
(including the expenses of any special audit and "cold comfort" letters 
required by or incident to such performance) and (vi) Securities Act 
liability insurance obtained by the Company in its sole discretion.  In 
addition, the Company shall pay its internal expenses (including, without 
limitation, all salaries and expenses of its officers and employees 
performing legal or accounting duties), the expense of any annual audit, the 
fees and expenses incurred in connection with the listing of the securities 
to be registered on any securities exchange on which similar securities 
issued by the Company are then listed and the fees and expenses of any 
person, including special experts, retained by the Company.  Notwithstanding 
the provisions of this Section 5, each seller of Registrable Securities shall 
pay all selling expenses and all registration expenses to the extent that the 
Company is prohibited by applicable Blue Sky laws from paying for or on 
behalf of such seller of Registrable Securities, and the Managing 
Underwriters shall pay the fees of their counsel in connection with any 
Underwritten Offering (other than Blue Sky qualifications).

    6.   INDEMNIFICATION.

         (a)  INDEMNIFICATION BY THE COMPANY.  The Company shall indemnify 
and hold harmless each Initial Purchaser, each Holder and each person, if 
any, who controls the Initial Purchasers or any Holder (within the meaning of 
either Section 15 of the Securities Act or Section 20(a) of the Exchange Act) 
from and against all losses, liabilities, damages and expenses (including, 
without limitation, any legal or other expenses reasonably incurred in 
connection with defending or investigating any such action or claim) 
(collectively, "Losses"), caused by any untrue statement or alleged untrue 
statement of a material fact contained in any Registration Statement or 
Prospectus or in any amendment or supplement thereto or in any preliminary 
prospectus, or caused by any omission or alleged omission to state therein a 
material fact required to be stated therein or necessary to make the 
statements therein in light of the circumstances in which they were made not 
misleading, except insofar as such Losses are caused 


                                      15.


by the information furnished to the Company in writing by the Initial 
Purchasers or such Holder expressly for use therein; PROVIDED, that the 
Company shall not be liable to any Holder of Registrable Securities (or any 
person controlling such Holder) to the extent that any such Losses are caused 
by an untrue statement or alleged untrue statement or omission or alleged 
omission made in any preliminary prospectus if either (A)(i) such Holder 
failed to send or deliver a copy of the Prospectus with or prior to the 
delivery of written confirmation of the sale by such Holder to the person 
asserting the claims from which such Losses result and (ii) the Prospectus 
would have corrected such untrue statement or alleged untrue statement or 
such omission or alleged omission, (B)(x) such untrue statement or alleged 
untrue statement, omission or alleged omission is corrected in an amendment 
or supplement to the Prospectus and (y) having previously been furnished by 
or on behalf of the Company with copies of the Prospectus as so amended or 
supplemented, such holder thereafter fails to deliver such Prospectus as so 
amended or supplemented, with or prior to the delivery of written 
confirmation of the sale of a Registrable Security to the person asserting 
the claim from which such Losses result or (C) such Holder effected 
transactions pursuant to a Registration Statement or Prospectus during any 
suspension or delay of a Selling Period in accordance with Section 2(d)(ii) 
hereof.  The Company shall also indemnify each underwriter and each person 
who controls such person (within the meaning of Section 15 of the Securities 
Act or Section 20(a) of the Exchange Act) to the same extent and with the 
same limitations as provided above with respect to the indemnification of the 
Initial Purchasers or the holders of Registrable Securities.

         (b)  INDEMNIFICATION BY HOLDER OF REGISTRABLE SECURITIES.  Each 
Holder agrees, and such agreement shall be evidenced by the Holder delivering 
the notice described in Section 2(d) hereof, severally and not jointly to 
indemnify and hold harmless the Initial Purchasers, the other selling 
Holders, the Company, its directors, its officers who sign a Registration 
Statement, and each person, if any, who controls the Company, the Initial 
Purchasers and any other selling Holder (within the meaning of either Section 
15 of the Securities Act or Section 20 of the Exchange Act), from and against 
all losses arising out of or based upon any untrue statement of a material 
fact contained in any Registration Statement, Prospectus or preliminary 
prospectus or arising out of or based upon any omission of a material fact 
required to be stated therein or necessary to make the statements therein not 
misleading, to the extent, but only to the extent, that such untrue statement 
or omission is contained in any information relating to such Holder so 
furnished in writing by such Holder to the Company expressly for use in such 
Registration Statement or Prospectus.  In no event shall the liability of any 
selling holder of Registrable Securities hereunder be greater in amount than 
the dollar amount of the proceeds received by such holder upon the sale of 
the Registrable Securities giving rise to such indemnification obligation.

         (c)  CONDUCT OF INDEMNIFICATION PROCEEDINGS.  In case any proceeding 
(including any governmental investigation) shall be instituted involving any 
person in respect of which indemnity may be sought pursuant to either of the 
two preceding paragraphs, such person (the "indemnified party") shall 
promptly notify the person against whom such indemnity may be sought (the 
"indemnifying party") in writing and the indemnifying party, upon request of 
the indemnified party, shall retain counsel reasonably satisfactory to the 
indemnified party to 


                                      16.


represent the indemnified party and any others the indemnifying party may 
designate in such proceeding and shall pay the reasonable fees and 
disbursements of such counsel related to such proceeding.  In any such 
proceeding, any indemnified party 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 party unless (i) the indemnifying party and the indemnified 
party shall have mutually agreed to the retention of such counsel or (ii) the 
named parties to any such proceeding (including any impleaded parties) 
include both the indemnifying party and the indemnified party 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 the indemnifying party shall not, in respect of the legal expenses of 
any indemnified party in connection with any proceeding or related 
proceedings in the same jurisdiction, be liable for (a) the fees and expenses 
of more than one separate firm (in addition to any local counsel) for the 
Initial Purchasers and all persons, if any, who control the Initial 
Purchasers within the meaning of either Section 15 of the Securities Act or 
Section 20 of the Exchange Act, (b) the fees and expenses of more than one 
separate firm (in addition to any local counsel) for all Holders and all 
persons, if any, who control any Holder within the meaning of either Section 
15 of the Securities Act or Section 20 of the Exchange Act, and (c) the fees 
and expenses of more than one separate firm (in addition to any local 
counsel) for the Company, its directors, its officers who sign a Registration 
Statement and each person, if any, who controls the Company within the 
meaning of either such Section, and that all such fees and expenses shall be 
reimbursed as they are incurred.  In the case of any such separate firm for 
the Company, and such directors, officers and control persons of the Company, 
such firm shall be designated in writing by the Company.  In such case 
involving the Initial Purchasers and persons who control the Initial 
Purchasers, such firm shall be designated in writing by Deutsche Morgan 
Grenfell Inc.  In such case involving the Holders and such persons who 
control Holders, such firm shall be designated in writing by the holders of 
the majority of Registrable Securities sold pursuant to the Registration 
Statement.  The indemnifying party shall not be liable for any settlement of 
any proceeding effected without its written consent, but if settled with such 
consent or if there be a final judgment for the plaintiff, the indemnifying 
party agrees to indemnify the indemnified party from and against any loss or 
liability by reason of such settlement or judgment. No indemnifying party 
shall, without the prior written consent of the indemnified party, effect any 
settlement of any pending or threatened proceeding in respect of which any 
indemnified party is or could have been a party and indemnity could have been 
sought hereunder by such indemnified party, unless such settlement includes 
an unconditional release of such indemnified party from all liability on 
claims that are the subject matter of such proceeding.

         (d)  CONTRIBUTION.  If the indemnification provided for in this 
Section 6 is unavailable to an indemnified party under Section 6(a) or 6(b) 
hereof in respect of any Losses or is insufficient to hold such indemnified 
party harmless, then each applicable indemnifying party, in lieu of 
indemnifying such indemnified party, shall contribute to the amount paid or 
payable by such indemnified party as a result of such Losses, (i) in such 
proportion as is appropriate to reflect the relative benefits received by the 
indemnifying party or parties on the one hand and the indemnified party or 
parties on the other hand or (ii) if the allocation provided by clause (i) 
above is not permitted by applicable law, in such proportion as is 
appropriate to reflect not only the relative benefits referred to in clause 
(i) above but also the relative fault of the 


                                      17.


indemnifying party or parties on the one hand and of the indemnified party or 
parties on the other hand in connection with the statements or omissions that 
resulted in such Losses, as well as any other relevant equitable 
considerations. Benefits received by the Company shall be deemed to be equal 
to the total net proceeds from the initial placement (before deducting 
expenses) of the Notes pursuant to the Purchase Agreement.  Benefits received 
by the Initial Purchasers shall be deemed to be equal to the total purchase 
discounts and commissions received by it pursuant to the Purchase Agreement, 
and benefits received by any other Holders shall be deemed to be equal to the 
value of receiving Notes registered under the Securities Act.  Benefits 
received by any underwriter shall be deemed to be equal to the total 
underwriting discounts and commissions, as set forth on the cover page of the 
Prospectus forming a part of the Registration Statement which resulted in 
such Losses.  The relative fault of the Holders on the one hand and the 
Company on the other hand 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 Holders or by the Company and the parties' 
relative intent, knowledge, access to information and opportunity to correct 
or prevent such statement or omission.  The Holders' respective obligations 
to contribute pursuant to this paragraph are several in proportion to the 
respective number of Registrable Securities they have sold pursuant to a 
Registration Statement, and not joint.

    The parties hereto agree that it would not be just and equitable if 
contribution pursuant to this Section 6(d) were determined by PRO RATA 
allocation or by any other method or allocation that does not take into 
account the equitable considerations referred to in the immediately preceding 
paragraph. The amount paid or payable by an indemnified party as a result of 
the Losses 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 reasonably incurred by such indemnified party in connection 
with investigating or defending any such action or claim.  Notwithstanding 
this Section 6(d), an indemnifying party that is a selling Holder of 
Registrable Securities shall not be required to contribute any amount in 
excess of the amount by which the total price at which the Registrable 
Securities sold by such indemnifying party and distributed to the public were 
offered to the public exceeds the amount of any damages which such 
indemnifying party has otherwise been required to pay by reason of such 
untrue or alleged untrue statement or omission or alleged omission.  No 
person guilty of fraudulent misrepresentation (within the meaning of Section 
11(f) of the Securities Act) shall be entitled to contribution from any 
person who was not guilty of such fraudulent misrepresentation.

    The indemnity, contribution and expense reimbursement obligations of the 
Company hereunder shall be in addition to any liability the Company may 
otherwise have hereunder, under the Purchase Agreement or otherwise.  The 
provisions of this Section 6 shall survive so long as Registrable Securities 
remain outstanding, notwithstanding any transfer of the Registrable 
Securities by any holder or any termination of this Agreement.

    The indemnity and contribution provisions 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 
the Initial Purchasers, any Holder or any person 


                                      18.


controlling any Holder, or the Company, its officers or directors or any 
person controlling the Company and (iii) the sale of any Registrable 
Securities by any Holder.  

    7.   INFORMATION REQUIREMENTS.

         (a)  The Company shall file the reports required to be filed by it 
under the Securities Act and the Exchange Act, and if at any time the Company 
is not required to file such reports, it will, upon the request of any holder 
of Registrable Securities, make publicly available other information so long 
as necessary to permit sales pursuant to Rule 144 and Rule 144A under the 
Securities Act.  The Company further covenants that it will cooperate with 
any holder of Registrable Securities and take such further reasonable action 
as any holder of Registrable Securities may reasonably request (including, 
without limitation making such reasonable representations as any such holder 
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 Rule 
144 and Rule 144A under the Securities Act.  Upon the request of any holder 
of Registrable Securities, the Company shall deliver to such holder a written 
statement as to whether it has complied with such filing requirements.  
Notwithstanding the foregoing, nothing in this Section 7 shall be deemed to 
require the Company to register any of its securities under any section of 
the Exchange Act.

         (b)  The Company shall file the reports required to be filed by it 
under the Exchange Act and shall comply with all other requirements set forth 
in the instructions to Form S-3 in order to allow the Company to be eligible 
to file registration statements on Form S-3.

    8.   MISCELLANEOUS.

         (a)  REMEDIES.  In the event of a breach by the Company of its 
obligations under this Agreement, each holder of Registrable Securities, in 
addition to being entitled to exercise all rights granted by law, including 
recovery of damages, will be entitled to specific performance of its rights 
under this Agreement, provided that the sole damages payable for a violation 
of the terms of this Agreement for which Liquidated Damages are expressly 
provided pursuant to Section 2(e) hereof shall be such Liquidated Damages.  
The Company agrees that monetary damages would not be adequate compensation 
for any loss incurred by reason of a breach by it of any of the provisions of 
this Agreement and hereby further agrees that, in the event of any action for 
specific performance in respect of such breach, it shall waive the defense 
that a remedy at law would be adequate.

         (b)  NO CONFLICTING AGREEMENTS.  The Company has not, as of the date 
hereof and shall not, on or after the date of this Agreement, enter into any 
agreement with respect to its securities which conflicts with the rights 
granted to the holders of Registrable Securities in this Agreement.  The 
Company represents and warrants that the rights granted to the holders of 
Registrable Securities hereunder do not in any way conflict with the rights 
granted to the holders of the Company's securities under any other agreements.


                                      19.


         (c)  AMENDMENTS AND WAIVERS.  The provisions of this Agreement, 
including the provisions of this sentence, may not be amended, modified or 
supplemented, and waivers or consents to departures from the provisions 
hereof may not be given, unless the Company has obtained the written consent 
of holders of a majority of the then outstanding Common Stock constituting 
Registrable Securities (with holders of Notes deemed to be the holders, for 
purposes of this Section, of the number of outstanding shares of Common Stock 
into which such Notes are convertible).  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 the rights of other 
holders of Registrable Securities may be given by holders of at least a 
majority of the Registrable Securities being sold by such holders; PROVIDED, 
that the provisions of this sentence may not be amended, modified, or 
supplemented except in accordance with the provisions of the immediately 
preceding sentence.

         (d)  NOTICES.  All notices and other communications provided for or 
permitted hereunder shall be made in writing and shall be deemed given (i)

         (e)  OWNER OF REGISTRABLE SECURITIES.  The Company will maintain, or 
will cause its registrar and transfer agent to maintain, a register with 
respect to the Registrable Securities in which all transfers of Registrable 
Securities of which the Company has received notice will be recorded.  The 
Company may deem and treat the person in whose name Registrable Securities 
are registered in such register of the Company as the owner thereof for all 
purposes, including, without limitation, the giving of notices under this 
Agreement.

         (f)  APPROVAL OF HOLDERS.  Whenever the consent or approval of 
holders of a specified percentage 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) (other than the 
Initial Purchasers or subsequent holders of Registrable Securities if such 
subsequent holders are deemed to be such affiliates solely by reason of their 
holdings of such Registrable Securities) shall not be counted in determining 
whether such consent or approval was given by the holders of such required 
percentage.

         (g)  SUCCESSORS AND ASSIGNS.  Any person who purchases any 
Registerable Securities from an Initial Purchaser shall be deemed, for 
purposes of this Agreement, to be an assignee of such Initial Purchaser.  The 
Agreement shall inure to the benefit of and be binding upon the successors 
and assigns of each of the parties and shall inure to the benefit of and be 
binding upon each holder of any Registrable Securities.

         (h)  COUNTERPARTS.  This Agreement may be executed in any number of 
counterparts and by the parties hereto in separate counterparts, each of 
which when so executed shall be deemed to be original and all of which taken 
together shall constitute one and the same agreement.

         (i)  HEADINGS.  The headings in this Agreement are for convenience 
of reference only and shall not limit or otherwise affect the meaning hereof.


                                      21.


         (j)  GOVERNING LAW.  THIS AGREEMENT SHALL BE GOVERNED BY AND 
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AS APPLIED TO 
CONTRACTS MADE AND PERFORMED WITHIN THE STATE OF NEW YORK WITHOUT REGARD TO 
PRINCIPLES OF CONFLICT OF LAWS.

         (k)  SEVERABILITY.  If any term, provision, covenant or restriction 
of this Agreement is held to be invalid, illegal, void or unenforceable, the 
remainder of the terms, provisions, covenants and restrictions set forth 
herein shall remain in full force and effect and shall in no way be affected, 
impaired or invalidated thereby, and the parties hereto shall use their best 
efforts to find and employ an alternative means to achieve the same or 
substantially the same result as that contemplated by such term, provision, 
covenant or restriction.  It is hereby stipulated and declared to be the 
intention of the parties that they would have executed the remaining terms, 
provisions, covenants and restrictions without including any of such which 
may be hereafter declared invalid, illegal void or unenforceable.

         (l)  ENTIRE AGREEMENT.  This Agreement is intended by the parties as 
a final expression of their agreement and is intended to be a complete and 
exclusive statement of the agreement and understanding of the parties hereto 
in respect of the subject matter contained herein and the registration rights 
granted by the Company with respect to the Common Stock of the Company into 
which Notes are convertible sold pursuant to the Purchase Agreement.  Except 
as provided in the Purchase Agreement, there are no restrictions, promises, 
warranties or undertakings, other than those set forth or referred to herein, 
with respect to the registration rights granted by the Company with respect 
to the Common Stock of the Company to which the Notes are convertible.  This 
Agreement supersedes all prior agreements and understandings among the 
parties with respect to such registration rights.

         (m)   ATTORNEYS' FEES.  In any action or proceeding brought to 
enforce provision of this Agreement, or where any provision hereof is validly 
asserted as a defense, the prevailing party, as determined by the court, 
shall be entitled to recover reasonable attorneys' fees in addition to any 
other available remedy.

         (n)  FURTHER ASSURANCES.  Each of the parties hereto shall use all 
reasonable efforts to take, or cause to be taken, all appropriate action, do 
or cause to be done all things reasonably necessary, proper or advisable 
under applicable law, and execute and deliver such documents and other 
papers, as may be required to carry out the provisions of this Agreement and 
the other documents contemplated hereby and consummate and make effective the 
transactions contemplated hereby.

         (o)  TERMINATION.  This Agreement and the obligations of the parties 
hereunder shall terminate upon the end of the Effectiveness Period, except 
for any liabilities or obligations under Sections 4, 5 or 6 hereof and the 
obligations to make payments of and provide for Liquidated Damages under 
Section 2(e) hereof to the extent such damages accrue prior to the end of the 
Effectiveness Period, each which shall remain in effect in accordance with 
their terms.
