          2.   REGISTRATION UNDER THE SECURITIES ACT.

          (a)  Except as set forth in Section 2(b) below, the Company and the
Guarantors agree to file under the Securities Act, as soon as practicable, but
no later than 90 days after the Closing Date, a registration statement relating
to an offer to exchange (such registration statement, the "EXCHANGE REGISTRATION
STATEMENT", and such offer, the "EXCHANGE OFFER") any and all of the Securities
for a like aggregate principal amount of debt securities issued by the Company
and guaranteed by the Guarantors, which debt securities and guarantees are
substantially identical to the Securities and the related Guarantees,
respectively (and are entitled to the benefits of a trust indenture which is
substantially identical to the Indenture or is the Indenture and which has been
qualified under the Trust Indenture Act), except that they have been registered
pursuant to an effective registration statement under the Securities Act and do
not contain provisions for the liquidated damages contemplated in Section 2(d)
below (such new debt securities hereinafter called "EXCHANGE SECURITIES"). The
Company agrees to use its reasonable best efforts to cause the Exchange
Registration Statement to become effective under the Securities Act as soon as
practicable, but no later than 180 days after the Closing Date. The Company
agrees that it shall cause the Exchange Offer to be registered under the
Securities Act on the appropriate form and to comply with all applicable tender
offer rules and regulations under the Exchange Act. The Company further agrees
to use its best efforts to commence and complete the Exchange Offer promptly,
but no later than 45 days after such registration statement has become
effective, hold the Exchange Offer open for at least 30 days and exchange
Exchange Securities for all Registrable Securities that have been properly
tendered and not withdrawn on or prior to the expiration of the Exchange Offer.
The Exchange Offer will be deemed to have been "completed" only if the debt
securities and related guarantees received by holders other than Restricted
Holders in the Exchange Offer for Registrable Securities are, upon receipt,
transferable by each such holder without need for further compliance with
Section 5 of the Securities Act (except for the requirement to deliver a
prospectus included in the Exchange Registration Statement applicable to resales
by broker-dealers of Exchange Securities received by such broker-dealer pursuant
to an Exchange Offer in exchange for Registrable Securities other than those
acquired by the broker-dealer directly from the Company) and without material
restrictions under the blue sky or securities laws of a substantial majority of
the States of the United States of America. The Exchange Offer shall be deemed
to have been completed upon the earlier to occur of (i) the Company having
exchanged the Exchange Securities for all outstanding Registrable Securities
pursuant to the Exchange Offer and (ii) the Company having

                                        4
<Page>

exchanged, pursuant to the Exchange Offer, Exchange Securities for all
Registrable Securities that have been properly tendered and not withdrawn before
the expiration of the Exchange Offer, which shall be on a date that is at least
30 days following the commencement of the Exchange Offer. The Company agrees (x)
to include in the Exchange Registration Statement a prospectus for use in any
resales by any holder of Exchange Securities that is a broker-dealer (where such
Exchange Security was received by a broker-dealer in an Exchange Offer in
exchange for a Registrable Security that was acquired by such broker-dealer for
its own account as a result of market-making or other trading activities, so
long as such Registrable Security was not acquired directly from the Company or
an affiliate of the Company) and (y) to keep such Exchange Registration
Statement effective for a period (the "RESALE PERIOD") beginning when Exchange
Securities are first issued in the Exchange Offer and ending upon the earlier of
the expiration of the 180th day after the Exchange Offer has been completed or
such time as such broker-dealers no longer own any Registrable Securities. With
respect to such Exchange Registration Statement, such holders shall have the
benefit of the rights of indemnification and contribution set forth in Sections
6(a), (c), (d) and (e) hereof.

          (b)  If (i) on or prior to the time the Exchange Offer is completed
existing Commission interpretations are changed such that the debt securities or
the related guarantees received by holders other than Restricted Holders in the
Exchange Offer for Registrable Securities are not or would not be, upon receipt,
transferable by each such holder without need for further compliance with
Section 5 of the Securities Act (except for the requirement to deliver a
prospectus included in the Exchange Registration Statement applicable to resales
by broker-dealers of Exchange Securities received by such broker-dealer pursuant
to an Exchange Offer in exchange for Registrable Securities other than those
acquired by the broker-dealer directly from the Company), (ii) the Exchange
Offer has not been completed within 210 days following the Closing Date or (iii)
the Exchange Offer is not available to any holder of the Securities and such
holder notifies the Company in writing prior to the 210th day following the
Closing Date (A) that it is prohibited by law or Commission policy from
participating in the Exchange Offer, (B) that it may not resell the Exchange
Securities acquired by it in the Exchange Offer to the public without delivering
a prospectus and the prospectus contained in the Exchange Registration Statement
is not appropriate or available for such resales or (C) that it is a
broker-dealer and owns Registrable Securities acquired directly from the Company
or an affiliate of the Company, the Company shall, in lieu of (or, in the case
of clause (iii), in addition to) conducting the Exchange Offer contemplated by
Section 2(a), file under the Securities Act as soon as practicable, but no later
than 60 days after the time such obligation to file arises, a "shelf"
registration statement providing for the registration of, and the sale on a
continuous or delayed basis by the holders of, all of the Registrable
Securities, pursuant to Rule 415 or any similar rule that may be adopted by the
Commission (such filing, the "SHELF REGISTRATION" and such registration
statement, the "SHELF REGISTRATION STATEMENT"). The Company agrees to use its
reasonable best efforts (x) to cause the Shelf Registration Statement to become
or be declared effective no later than 120 days after such Shelf Registration
Statement is filed and to keep such Shelf Registration Statement continuously
effective for a period ending on the earlier of the second anniversary of the
Effective Time or such time as there are no longer any Registrable Securities
outstanding, provided, however, that no holder shall be entitled to be named as
a selling securityholder in the Shelf Registration Statement or to use the
prospectus forming a part thereof for resales of Registrable Securities unless
such holder is an Electing Holder who agrees to be bound by all of the
provisions of this Agreement applicable to such holder, and (y) after the
Effective Time of the Shelf Registration Statement, promptly upon the request of
any holder of Registrable Securities that is not then an Electing Holder, to
take any action reasonably necessary to enable such holder to use the prospectus
forming a part thereof for resales of Registra-

                                        5
<Page>

ble Securities, including, without limitation, any action necessary to
identify such holder as a selling securityholder in the Shelf Registration
Statement, provided, however, that nothing in this Clause (y) shall relieve
any such holder of the obligation to return a completed and signed Notice and
Questionnaire to the Company in accordance with Section 3(d)(iii) hereof. The
Company further agrees to supplement or make amendments to the Shelf
Registration Statement, as and when required by the rules, regulations or
instructions applicable to the registration form used by the Company for such
Shelf Registration Statement or by the Securities Act or rules and
regulations thereunder for shelf registration, and the Company agrees to
furnish to each Electing Holder copies of any such supplement or amendment
prior to its being used or promptly following its filing with the Commission.

          (c)  Notwithstanding the foregoing, the Company, upon advising the
Purchasers in writing, may, pursuant to the advice of outside counsel to the
Company, delay the filing or effectiveness of any Exchange Registration
Statement or Shelf Registration Statement (if not then filed or effective, as
applicable) or suspend, or otherwise fail to maintain, the effectiveness
thereof, for a period (the "BLACKOUT PERIOD") not to exceed an aggregate of 60
days in any twelve consecutive month period in the event that (1) the Board of
Directors of the Company reasonably and in good faith determines that the
premature disclosure of a material event at such time would have a material
adverse effect on the Company's business, operations or prospects or (2) the
disclosure otherwise relates to a material business transaction which has not
been publicly disclosed and the Board of Directors of the Company reasonably and
in good faith determines that any such disclosure would jeopardize the success
of such transaction; PROVIDED, that, upon the termination of such Blackout
Period, the Company promptly shall advise the Purchasers that such Blackout
Period has been terminated.

          (d)  In the event that (i) the Company has not filed the Exchange
Registration Statement or Shelf Registration Statement on or before the date on
which such registration statement is required to be filed pursuant to Section
2(a) or 2(b), respectively, or (ii) such Exchange Registration Statement or
Shelf Registration Statement has not become effective or been declared effective
by the Commission within 180 days after the Closing Date (in the case of Section
2(a)) or 120 days after the Shelf Registration Statement is filed (in the case
of Section 2(b)), or (iii) the Exchange Offer has not been completed within 45
days after the initial effective date of the Exchange Registration Statement
relating to the Exchange Offer (if the Exchange Offer is then required to be
made) or (iv) any Exchange Registration Statement or Shelf Registration
Statement required by Section 2(a) or 2(b) hereof is filed and declared
effective but shall thereafter, prior to the time such Exchange Registration
Statement or Shelf Registration Statement is no longer required to be effective
pursuant to Section 2(a) or 2(b), either be withdrawn by the Company or shall
become subject to an effective stop order issued pursuant to Section 8(d) of the
Securities Act suspending the effectiveness of such registration statement
(except during a Blackout Period permitted by this Agreement) without being
succeeded immediately by an additional registration statement filed and declared
effective (each such event referred to in clauses (i) through (iv), a
"REGISTRATION DEFAULT" and each period during which a Registration Default has
occurred and is continuing, a "REGISTRATION DEFAULT PERIOD"), then the Company
shall pay to the holders liquidated damages for such Registration Default,
subject to the provisions of Section 9(b) ("LIQUIDATED DAMAGES"). Liquidated
Damages shall accrue at a per annum rate of 0.50% of the principal amount of
Registrable Securities for the first 90 days of the Registration Default Period,
at a per annum rate of 1.00% of the principal amount of Registrable Securities
for the second 90 days of the Registration Default Period, at a per annum rate
of 1.50% of the principal amount of Registrable Securities for the third 90 days
of the Registration Default Period and at a per annum rate of 2.00% of the
principal amount of Registrable Securi-

                                        6
<Page>

ties thereafter for the remaining portion of the Registration Default Period,
such Registration Default Period ending on the earlier of (x) the date on
which all Registration Defaults have been cured and (y) the date on which all
the Securities otherwise become freely transferable by all holders of the
Securities other than affiliates of the Company or the Guarantors without
further registration under the Securities Act. Notwithstanding the forgoing,
(A) the amount of Liquidated Damages payable shall not increase solely
because more than one Registration Default has occurred and (B) for so long
as a holder of Registrable Securities is not an Electing Holder, such holder
shall not be entitled to Liquidated Damages with respect to a Registration
Default that pertains to a Shelf Registration Statement.

          (e)  The Company and the Guarantors shall take all actions necessary
or advisable to be taken by them to ensure that the transactions contemplated
herein are effected as so contemplated, including all actions reasonably
necessary or desirable to register the Guarantees, under the registration
statement contemplated in Section 2(a) or 2(b) hereof, as applicable.

          (f)  Any reference herein to a registration statement as of any time
shall be deemed to include any document incorporated, or deemed to be
incorporated, therein by reference as of such time and any reference herein to
any post-effective amendment to a registration statement as of any time shall be
deemed to include any document incorporated, or deemed to be incorporated,
therein by reference as of such time.

          3.   REGISTRATION  PROCEDURES.  If the Company files a registration
statement pursuant to Section 2(a) or Section 2(b) hereof, the following
provisions shall apply:

          (a)  At or before the Effective Time of the Exchange Offer or the
     Shelf Registration, as the case may be, the Company shall qualify the
     Indenture under the Trust Indenture Act.

          (b)  In the event that such qualification would require the
     appointment of a new trustee under the Indenture, the Company shall appoint
     a new trustee thereunder pursuant to the applicable provisions of the
     Indenture.

          (c)  In connection with the Company's obligations with respect to the
     registration of Exchange Securities as contemplated by Section 2(a) (the
     "EXCHANGE REGISTRATION"), if applicable, the Company shall, as soon as
     practicable (or as otherwise specified):

               (i)     prepare and file with the Commission, as soon as
          practicable but no later than 90 days after the Closing Date, an
          Exchange Registration Statement on any appropriate form under the
          Securities Act which may be utilized by the Company and which shall
          permit the Exchange Offer and resales of Exchange Securities by
          broker-dealers during the Resale Period to be effected as contemplated
          by Section 2(a), and use its reasonable best efforts to cause such
          Exchange Registration Statement to become effective as soon as
          practicable thereafter, but no later than 180 days after the Closing
          Date;

               (ii)    as soon as practicable prepare and file with the
          Commission such amendments and supplements to such Exchange
          Registration Statement and the prospectus included therein as may be
          reasonably necessary to effect and maintain the effectiveness of such
          Exchange Registration Statement for the periods

                                        7
<Page>

          and purposes contemplated in Section 2(a) hereof and as may be
          required by the applicable rules and regulations of the Commission and
          the instructions applicable to the form of such Exchange Registration
          Statement, and promptly provide each broker-dealer holding Exchange
          Securities with such number of copies of the prospectus included
          therein (as then amended or supplemented), in conformity in all
          material respects with the requirements of the Securities Act and the
          Trust Indenture Act and the rules and regulations of the Commission
          thereunder, as such broker-dealer reasonably may request prior to the
          expiration of the Resale Period, for use in connection with resales of
          Exchange Securities;

               (iii)   promptly notify each broker-dealer that has requested or
          received copies of the prospectus included in such registration
          statement, and confirm such advice in writing, (A) when such Exchange
          Registration Statement or the prospectus included therein or any
          prospectus amendment or supplement or post-effective amendment has
          been filed, and, with respect to such Exchange Registration Statement
          or any post-effective amendment, when the same has become effective,
          (B) of any comments by the Commission and by the blue sky or
          securities commissioner or regulator of any state with respect thereto
          or any request by the Commission for amendments or supplements to such
          Exchange Registration Statement or prospectus or for additional
          information, (C) of the receipt by the Company of notification of the
          issuance by the Commission of any stop order suspending the
          effectiveness of such Exchange Registration Statement or the
          initiation or threatening of any proceedings for that purpose, (D) if
          at any time the representations and warranties of the Company
          contemplated by Section 5 cease to be true and correct in all material
          respects, (E) of the receipt by the Company of any notification with
          respect to the suspension of the qualification of the Exchange
          Securities for sale in any jurisdiction or the initiation or
          threatening of any proceeding for such purpose, or (F) at any time
          during the Resale Period when a prospectus is required to be delivered
          under the Securities Act, that such Exchange Registration Statement,
          prospectus, prospectus amendment or supplement or post-effective
          amendment does not conform in all material respects to the applicable
          requirements of the Securities Act and the Trust Indenture Act and the
          rules and regulations of the Commission thereunder or contains an
          untrue statement of a material fact or omits to state any material
          fact required to be stated therein or necessary to make the statements
          therein not misleading in light of the circumstances then existing;

               (iv)    in the event that the Company would be required, pursuant
          to Section 3(c)(iii)(F) above, to notify any broker-dealers holding
          Exchange Securities, without delay prepare and furnish to each such
          holder a reasonable number of copies of a prospectus supplemented or
          amended so that, as thereafter delivered to purchasers of such
          Exchange Securities during the Resale Period, such prospectus shall
          conform in all material respects to the applicable requirements of the
          Securities Act and the Trust Indenture Act and the rules and
          regulations of the Commission thereunder and shall 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 in light of the circumstances then existing;

                                        8

          proposed or effected, as the case may be;

               (xix)   in the event that any broker-dealer registered under the
          Exchange Act shall underwrite any Registrable Securities or
          participate as a member of an underwriting syndicate or selling group
          or "assist in the distribution" (within the meaning of the Conduct
          Rules (the "CONDUCT RULES") of the National Association of Securities
          Dealers, Inc. ("NASD") or any successor thereto, as amended from time
          to time) thereof, whether as a holder of such Registrable Securities
          or as an underwriter, a placement or sales agent or a broker or dealer
          in respect thereof, or otherwise, assist such broker-dealer in
          complying with the requirements of such Conduct Rules, including by
          (A) if such Conduct Rules shall so require, engaging a "qualified
          independent underwriter" (as defined in such Conduct Rules) to
          participate in the preparation of the Shelf Registration Statement
          relating to such Registrable Securities, to exercise usual standards
          of due diligence in respect thereto and, if any portion of the
          offering contemplated by such Shelf Registration Statement is an
          underwritten offering or is made through a placement or sales agent,
          to recommend the yield of such Registrable Securities, (B)
          indemnifying any such qualified independent underwriter to the extent
          of the indemnification of underwriters provided in Section 6 hereof
          (or to such other customary extent as may be requested by such
          underwriter), and (C) providing such information to such broker-dealer
          as may be required in order for such broker-dealer to comply with the
          requirements of the Conduct Rules; and

               (xx)    comply with all applicable rules and regulations of the
          Commission, and make generally available to its securityholders as
          soon as practicable but in any event not later than eighteen months
          after the effective date of such Shelf Registration Statement, an
          earning statement of the Company and its subsidiaries complying with
          Section 11(a) of the Securities Act (including, at the option of the
          Company, Rule 158 thereunder).

          (e)  In the event that the Company would be required, pursuant to
     Section 3(d)(viii)(F) above, to notify the Electing Holders, the placement
     or sales agent, if any, therefor and the managing underwriters, if any,
     thereof, the Company shall without delay prepare and furnish to each of the
     Electing Holders, to each placement or sales agent, if any, and to each
     such underwriter, if any, a reasonable number of copies of a prospectus
     supplemented or amended so that, as thereafter delivered to purchasers of
     Registrable Securities, such prospectus shall conform in all material
     respects to the applicable requirements of the Securities Act and the Trust
     Indenture Act and the rules and regulations of the Commission thereunder
     and shall 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 in light of the circumstances then
     existing. Each Electing Holder agrees that upon receipt of any notice from
     the Company pursuant to Section 3(d)(viii)(F) hereof, such Electing Holder
     shall forthwith discontinue the disposition of Registrable Securities
     pursuant to the Shelf Registration Statement applicable to such Registrable
     Securities until such Electing Holder shall have received copies of

                                       15
<Page>

     such amended or supplemented prospectus, and if so directed by the Company,
     such Electing Holder shall deliver to the Company (at the Company's
     expense) all copies, other than permanent file copies, then in such
     Electing Holder's possession of the prospectus covering such Registrable
     Securities at the time of receipt of such notice.

          (f)  In the event of a Shelf Registration, in addition to the
     information required to be provided by each Electing Holder in its Notice
     Questionnaire, the Company may require such Electing Holder to furnish to
     the Company such additional information regarding such Electing Holder and
     such Electing Holder's intended method of distribution of Registrable
     Securities as may be required in order to comply with the Securities Act.
     Each such Electing Holder agrees to notify the Company as promptly as
     practicable of any inaccuracy or change in information previously furnished
     by such Electing Holder to the Company or of the occurrence of any event in
     either case as a result of which any prospectus relating to such Shelf
     Registration contains or would contain an untrue statement of a material
     fact regarding such Electing Holder or such Electing Holder's intended
     method of disposition of such Registrable Securities or omits to state any
     material fact regarding such Electing Holder or such Electing Holder's
     intended method of disposition of such Registrable Securities required to
     be stated therein or necessary to make the statements therein not
     misleading in light of the circumstances then existing, and promptly to
     furnish to the Company any additional information required to correct and
     update any previously furnished information or required so that such
     prospectus shall not contain, with respect to such Electing Holder or the
     disposition of such Registrable Securities, 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 in light
     of the circumstances then existing.

          (g)  Until the expiration of two years after the Closing Date, the
     Company will not, and will not permit any of its "affiliates" (as defined
     in Rule 144) to, resell any of the Securities that have been reacquired by
     any of them except pursuant to an effective registration statement under
     the Securities Act.

          4.   REGISTRATION EXPENSES. The Company agrees to bear and to pay or
cause to be paid promptly all expenses incident to the Company's performance of
or compliance with this Exchange and Registration Rights Agreement, including
(a) all Commission and any NASD registration, filing and review fees and
expenses including fees and disbursements of counsel for the placement or sales
agent or underwriters in connection with such NASD (but not Commission)

3(d)(xix) hereof, (i) reasonable fees, disbursements and expenses of one counsel

least a majority in aggregate principal amount of the Registrable Securities
held by Electing Holders (which counsel shall be reasonably satisfactory to the
Company), (j) any fees charged by securities rating services for rating the
Securities, and (k) fees, expenses and disbursements of any other persons,
including special experts, retained by the Company in connection with such
registration (collectively, the "REGISTRATION EXPENSES"). To the extent that any
Registration Expenses are incurred, assumed or paid by any holder of Registrable
Securities or any placement or sales agent therefor or underwriter thereof, the
Company shall reimburse such person for the full amount of the Registration
Expenses so incurred, assumed or paid promptly after receipt of a request
therefor. Notwithstanding the foregoing, the holders of the Registrable
Securities being registered shall pay all agency fees and commissions and
underwriting discounts and commissions attributable to the sale of such
Registrable Securities and the fees and disbursements of any counsel or other
advisors or experts retained by such holders (severally or jointly), other than
the counsel and experts specifically referred to above.

          5.   REPRESENTATIONS AND WARRANTIES. Each of the Company and the
Guarantors represents and warrants to, and agrees with, each Purchaser and each
of the holders from time to time of Registrable Securities that:

          (a)  Each registration statement covering Registrable Securities and
     each prospectus (including any preliminary or summary prospectus) contained
     therein or furnished pursuant to Section 3(d) or Section 3(c) hereof and
     any further amendments or supplements to any such registration statement or
     prospectus, when it becomes effective or is filed with the Commission, as
     the case may be, and, in the case of an underwritten offering of
     Registrable Securities, at the time of the closing under the underwriting
     agreement relating thereto, will conform in all material respects to the
     requirements of the Securities Act and the Trust Indenture Act and the
     rules and regulations of the Commission thereunder and 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 at all times subsequent to the Effective Time when a
     prospectus would be required to be delivered under the Securities Act,
     other than from (i) such time as a notice has been given to holders of
     Registrable Securities pursuant to Section 3(d)(viii)(F) or Section
     3(c)(iii)(F) hereof until (ii) such time as the Company furnishes an
     amended or supplemented prospectus pursuant to Section 3(e) or Section
     3(c)(iv) hereof, each such registration statement, and each prospectus
     (including any summary prospectus) contained therein or furnished pursuant
     to Section 3(d) or Section 3(c) hereof, as then amended or supplemented,
     will conform in all material respects to the requirements of the Securities
     Act and the Trust Indenture Act and the rules and regulations of the
     Commission thereunder and 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 in the
     light of the circum-

                                       17
<Page>

     stances then existing; provided, however, that this representation and
     warranty shall not apply to any statements or omissions made in reliance
     upon and in conformity with information furnished in writing to the
     Company by a holder of Registrable Securities expressly for use therein.

          (b)  Any documents incorporated by reference in any prospectus
     referred to in Section 5(a) hereof, when they become or became effective or
     are or were filed with the Commission, as the case may be, will conform or
     conformed in all material respects to the requirements of the Securities
     Act or the Exchange Act, as applicable, and none of such documents will
     contain or contained an untrue statement of a material fact or will omit or
     omitted to state a material fact required to be stated therein or necessary
     to make the statements therein not misleading; provided, however, that this
     representation and warranty shall not apply to any statements or omissions
     made in reliance upon and in conformity with information furnished in
     writing to the Company by a holder of Registrable Securities expressly for
     use therein.

          (c)  The compliance by each of the Company and the Guarantors with all
     of the provisions of this Exchange and Registration Rights Agreement and
     the consummation of the transactions herein contemplated will not (i)
     conflict with or result in a breach of any of the terms or provisions of,
     or constitute a default under, any indenture, mortgage, deed of trust, loan
     agreement or other agreement or instrument to which the Company or any
     subsidiary of the Company is a party or by which the Company or any
     subsidiary of the Company is bound or to which any of the property or
     assets of the Company or any subsidiary of the Company is subject, nor will
     such action result in any violation of the provisions of the certificate of
     incorporation, as amended, by-laws, or other organizational documents of
     the Company or any of the Guarantors or (ii) result in any violation of any
     existing statute, order, rule or regulation of any court or governmental
     agency or body having jurisdiction over the Company or any subsidiary of
     the Company or any of their properties except, in the case of clauses (i)
     and (ii) above, such breaches or violations which would not, individually
     or in the aggregate, have a material adverse effect on the Securities or on
     the current or future consolidated financial position, stockholder's equity
     or results of operations of the Company and its subsidiaries or be
     reasonably likely to prevent the Company or the Guarantors from performing
     their respective obligations hereunder; and no consent, approval,
     authorization, order, registration or qualification of or with any such
     court or governmental agency or body is required for the consummation by
     the Company and the Guarantors of the transactions contemplated by this
     Exchange and Registration Rights Agreement, except the registration under
     the Securities Act of the Securities, qualification of the Indenture under
     the Trust Indenture Act and such consents, approvals, authorizations,
     registrations or qualifications as may be required under State securities
     or blue sky laws in connection with the offering and distribution of the
     Securities.

          (d)  This Exchange and Registration Rights Agreement has been duly
     authorized, executed and delivered by each of the Company and Guarantors.

          6.   INDEMNIFICATION.

          (a)  INDEMNIFICATION BY THE COMPANY AND THE GUARANTORS. The Company
and the Guarantors, jointly and severally, will indemnify and hold harmless each
of the holders of Registrable Securities included in an Exchange Registration
Statement, each of the Electing

                                       18
<Page>

Holders of Registrable Securities included in a Shelf Registration Statement and
each person who participates as a placement or sales agent or as an underwriter
in any offering or sale of such Registrable Securities against any losses,
claims, damages or liabilities, joint or several, to which such holder, agent or
underwriter may become subject under the Securities Act or otherwise, insofar as
such losses, claims, damages or liabilities (or actions in respect thereof)
arise out of or are based upon an untrue statement or alleged untrue statement
of a material fact contained in any Exchange Registration Statement or Shelf
Registration Statement, as the case may be, under which such Registrable
Securities were registered under the Securities Act, or any preliminary, final
or summary prospectus contained therein or furnished by the Company to any such
holder, Electing Holder, agent or underwriter, or any amendment or supplement
thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, and will reimburse such holder, such
Electing Holder, such agent and such underwriter for any legal or other expenses
reasonably incurred by them in connection with investigating or defending any
such action or claim as such expenses are incurred; provided, however, that
neither the Company nor the Guarantors shall be liable to any such person in any
such case 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 such registration statement, or
preliminary, final or summary prospectus, or amendment or supplement thereto, in
reliance upon and in conformity with written information furnished to the
Company by such person expressly for use therein.

          (b)  INDEMNIFICATION BY THE HOLDERS AND ANY AGENTS AND UNDERWRITERS.
The Company may require, as a condition to including any Registrable Securities
in any registration statement filed pursuant to Section 2(b) hereof and to
entering into any underwriting agreement with respect thereto, that the Company
shall have received an undertaking reasonably satisfactory to it from the
Electing Holder of such Registrable Securities and from each underwriter named
in any such underwriting agreement, severally and not jointly, to (i) indemnify
and hold harmless the Company, the Guarantors and all other holders of
Registrable Securities, against any losses, claims, damages or liabilities to
which the Company, the Guarantors or such other holders of Registrable
Securities may become subject, under the Securities Act or otherwise, insofar as
such losses, claims, damages or liabilities (or actions in respect thereof)
arise out of or are based upon an untrue statement or alleged untrue statement
of a material fact contained in such registration statement, or any preliminary,
final or summary prospectus contained therein or furnished by the Company to any
such Electing Holder, agent or underwriter, or any amendment or supplement
thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, in each case to the extent, but only to
the extent, that such untrue statement or alleged untrue statement or omission
or alleged omission was made in reliance upon and in conformity with written
information furnished to the Company by such Electing Holder or underwriter
expressly for use therein, and (ii) reimburse each of the Company and the
Guarantors for any legal or other expenses reasonably incurred by it in
connection with investigating or defending any such action or claim as such
expenses are incurred; provided, however, that no such Electing Holder shall be
required to undertake liability to any person under this Section 6(b) for any
amounts in excess of the dollar amount of the proceeds to be received by such
Electing Holder from the sale of such Electing Holder's Registrable Securities
pursuant to such registration.

          (c)  NOTICES OF CLAIMS, ETC. Promptly after receipt by an indemnified
party under subsection (a) or (b) above of written notice of the commencement of
any action, such in-

                                       19
<Page>

demnified party shall, if a claim in respect thereof is to be made against an
indemnifying party pursuant to the indemnification provisions of or
contemplated by this Section 6, notify such indemnifying party in writing of
the commencement of such action; but the omission so to notify the
indemnifying party shall not relieve it from any liability which it may have
to any indemnified party otherwise than under the indemnification provisions
of or contemplated by Section 6(a) or 6(b) hereof. In case any such action
shall be brought against any indemnified party and it shall notify an
indemnifying party of the commencement thereof, such indemnifying party shall
be entitled to participate therein and, to the extent that it shall wish,
jointly with any other indemnifying party similarly notified, to assume the
defense thereof, with counsel reasonably satisfactory to such indemnified
party (who shall not, except with the consent of the indemnified party, be
counsel to the indemnifying party), and, after notice from the indemnifying
party to such indemnified party of its election so to assume the defense
thereof, such indemnifying party shall not be liable to such indemnified
party for any legal expenses of other counsel or any other expenses, in each
case subsequently incurred by such indemnified party, in connection with the
defense thereof other than reasonable costs of investigation. No indemnifying
party shall, without the written consent of the indemnified party, effect the
settlement or compromise of, or consent to the entry of any judgment with
respect to, any pending or threatened action or claim in respect of which
indemnification or contribution may be sought hereunder (whether or not the
indemnified party is an actual or potential party to such action or claim)
unless such settlement, compromise or judgment (i) includes an unconditional
release of the indemnified party from all liability arising out of such
action or claim and (ii) does not include a statement as to or an admission
of fault, culpability or a failure to act by or on behalf of any indemnified
party.

          (d)  CONTRIBUTION. If for any reason the indemnification provisions
contemplated by Section 6(a) or Section 6(b) are unavailable to or insufficient
to hold harmless an indemnified party in respect of any losses, claims, damages
or liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities (or
actions in respect thereof) in such proportion as is appropriate to reflect the
relative fault of the indemnifying party and the indemnified party in connection
with the statements or omissions which resulted in such losses, claims, damages
or liabilities (or actions in respect thereof), as well as any other relevant
equitable considerations. The relative fault of such indemnifying party and
indemnified party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or omission or
alleged omission to state a material fact relates to information supplied by
such indemnifying party or by such indemnified party, and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission. The parties hereto agree that it would not be just
and equitable if contributions pursuant to this Section 6(d) were determined by
pro rata allocation (even if the holders or any agents or underwriters or all of
them were treated as one entity for such purpose) or by any other method of
allocation which does not take account of the equitable considerations referred
to in this Section 6(d). The amount paid or payable by an indemnified party as a
result of the losses, claims, damages, or liabilities (or actions in respect
thereof) referred to above shall be deemed to include any legal or other fees or
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this Section 6(d), no holder shall be required to contribute any
amount in excess of the amount by which the dollar amount of the proceeds
received by such holder from the sale of any Registrable Securities (after
deducting any fees, discounts and commissions applicable thereto) exceeds the
amount of any damages which such holder has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission, and no underwriter shall be required to contribute any amount in

                                       20
<Page>

excess of the amount by which the total price at which the Registrable
Securities underwritten by it and distributed to the public were offered to the
public exceeds the amount of any damages which such underwriter 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 holders' and any underwriters' obligations in this
Section 6(d) to contribute shall be several in proportion to the principal
amount of Registrable Securities registered or underwritten, as the case may be,
by them and not joint.

          (e)  The obligations of the Company and the Guarantors under this
Section 6 shall be in addition to any liability which the Company or the
Guarantors may otherwise have and shall extend, upon the same terms and
conditions, to each officer, director and partner of each holder, agent and
underwriter and each person, if any, who controls any holder, agent or
underwriter within the meaning of the Securities Act; and the obligations of the
holders and any agents or underwriters contemplated by this Section 6 shall be
in addition to any liability which the respective holder, agent or underwriter
may otherwise have and shall extend, upon the same terms and conditions, to each
officer and director of the Company or the Guarantors (including any person who,
with his consent, is named in any registration statement as about to become a
director of the Company or the Guarantors) and to each person, if any, who
controls the Company within the meaning of the Securities Act.

          7.   UNDERWRITTEN OFFERINGS.

          (a)  SELECTION OF UNDERWRITERS. If any of the Registrable Securities
covered by the Shelf Registration are to be sold pursuant to an underwritten
offering, the managing underwriter or underwriters thereof shall be designated
by Electing Holders holding at least a majority in aggregate principal amount of
the Registrable Securities to be included in such offering, provided that such
designated managing underwriter or underwriters is or are reasonably acceptable
to the Company.

          (b)  PARTICIPATION BY HOLDERS. Each holder of Registrable Securities
hereby agrees with each other such holder that no such holder may participate in
any underwritten offering hereunder unless such holder (i) agrees to sell such
holder's Registrable Securities on the basis provided in any underwriting
arrangements approved by the persons entitled hereunder to approve such
arrangements and (ii) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably
required under the terms of such underwriting arrangements.

          8.   RULE 144. The Company covenants to the holders of Registrable
Securities that to the extent it shall be required to do so under the Exchange
Act, the Company shall timely file the reports required to be filed by it under
the Exchange Act or the Securities Act (including the reports under Section 13
and 15(d) of the Exchange Act referred to in subparagraph (c)(1) of Rule 144
adopted by the Commission under the Securities Act) and the rules and
regulations adopted by the Commission thereunder, and shall 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 limitations
of the exemption provided by Rule 144 under the Securities Act, as such Rule may
be amended from time to time, or any similar or successor rule or regulation
hereafter adopted by the Commission. Upon the request of any holder of
Registrable Securities in con-

                                       21
<Page>

nection with that holder's sale pursuant to Rule 144, the Company shall
deliver to such holder a written statement as to whether it has complied with
such requirements.

          9.   MISCELLANEOUS.

          (a)  NO INCONSISTENT AGREEMENTS. The Company represents, warrants,
covenants and agrees that it has not granted, and shall not grant, registration
rights with respect to Registrable Securities or any other securities which
would be inconsistent with the terms contained in this Exchange and Registration
Rights Agreement.

          (b)  SPECIFIC PERFORMANCE. The parties hereto acknowledge that there
would be no adequate remedy at law if any of the Company or the Guarantors fails
to perform any of its obligations hereunder and that the Purchasers and the
holders from time to time of the Registrable Securities may be irreparably
harmed by any such failure, and accordingly agree that the Purchasers and such
holders, in addition to any other remedy to which they may be entitled at law or
in equity, shall be entitled to compel specific performance of the obligations
of the Company and the Guarantors under this Exchange and Registration Rights
Agreement in accordance with the terms and conditions of this Exchange and
Registration Rights Agreement, in any court of the United States or any State
thereof having jurisdiction.

          (c)  NOTICES. All notices, requests, claims, demands, waivers and
other communications hereunder shall be in writing and shall be deemed to have
been duly given when delivered by hand, if delivered personally or by courier,
or three days after being deposited in the mail (registered or certified mail,
postage prepaid, return receipt requested) as follows: If to the Company, to it
at 25 Greens Hill Lane, Rutland, Vermont 05701, and if to a holder, to the
address of such holder set forth in the security register or other records of
the Company, or to such other address as the Company or any such holder may have
furnished to the other in writing in accordance herewith, except that notices of
change of address shall be effective only upon receipt.

          (d)  PARTIES IN INTEREST. All the terms and provisions of this
Exchange and Registration Rights Agreement shall be binding upon, shall inure to
the benefit of and shall be enforceable by the parties hereto and the holders
from time to time of the Registrable Securities and the respective successors
and assigns of the parties hereto and such holders. In the event that any
transferee of any holder of Registrable Securities shall acquire Registrable
Securities, in any manner, whether by gift, bequest, purchase, operation of law
or otherwise, such transferee shall, without any further writing or action of
any kind, be deemed a beneficiary hereof for all purposes and such Registrable
Securities shall be held subject to all of the terms of this Exchange and
Registration Rights Agreement, and by taking and holding such Registrable
Securities such transferee shall be entitled to receive the benefits of, and be
