Ladies and Gentlemen:

          Apogent Technologies Inc., a Wisconsin corporation (the "COMPANY"),
proposes, subject to the terms and conditions stated herein, to issue and sell
$250,000,000 aggregate principal amount of its 2.25% Senior Convertible
Contingent Debt Securities (the "CODES") due 2021, with the several guarantees
(the "GUARANTEES" and together with the CODES, the "FIRM SECURITIES") of certain
of the Company's subsidiaries parties hereto (the "GUARANTORS") to Lehman
Brothers Inc., Credit Suisse First Boston Corporation, Banc of America
Securities LLC, ABN AMRO Rothschild LLC and UBS Warburg LLC (collectively, the
"INITIAL PURCHASERS").  In addition, the Company proposes to grant to the
Initial Purchasers an option (the "OPTION") to purchase up to an additional
$50,000,000 aggregate principal amount of its 2.25% Senior Convertible
Contingent Debt Securities due 2021 guaranteed by the Guarantors (the "OPTION
SECURITIES" and, together with the Firm Securities, the "SECURITIES").  This is
to confirm the agreement between the Company, the Guarantors and the Initial
Purchasers concerning the offer, issue and sale of the Securities.

          The Securities will be issued pursuant to an indenture (the
"INDENTURE") to be dated as of the First Delivery Date (as defined in Section
2(a)), among the Company, the Guarantors and The Bank of New York, as Trustee
(the "TRUSTEE").  The CODES will be convertible into duly and validly
authorized, fully paid and nonassessable shares of common stock, par value $0.01
per share (the "COMMON STOCK"), of the Company (such shares, the "CONVERSION
SHARES") on the terms, and subject to the conditions, set forth in the
Indenture.
<PAGE>

          The Securities will be offered and sold to the Initial Purchasers
without being registered under the Securities Act of 1933, as amended, and the
rules and regulations of the Securities and Exchange Commission (the
"COMMISSION") thereunder (collectively, the "SECURITIES ACT"), in reliance upon
an exemption therefrom.

          Holders of the Securities (including the Initial Purchasers and their
direct and indirect transferees) will be entitled to the benefits of a Resale
Registration Rights Agreement, dated as of the First Delivery Date, among the
Company, the Guarantors and the Initial Purchasers (the "REGISTRATION RIGHTS
AGREEMENT"), pursuant to which the Company and the Guarantors will agree to file
with the Commission one or more shelf registration statements pursuant to Rule
415 under the Securities Act (each, a "REGISTRATION STATEMENT") covering the
resale of the Securities and the Conversion Shares, and to use their best
efforts to cause each Registration Statement to be declared effective, in each
case within the time periods specified therein.

          This Agreement, the Indenture and the Registration Rights Agreement
are referred to herein collectively as the "TRANSACTION DOCUMENTS".

          1.  Representations, Warranties and Agreements of the Company and the
Guarantors.  Each of the Company and the Guarantors jointly and severally
represents, warrants to and agrees with, the Initial Purchasers that:

          (a)  The Company and the Guarantors have prepared a preliminary
     offering memorandum dated October 3, 2001 (the "PRELIMINARY OFFERING
     MEMORANDUM") and will prepare an offering memorandum dated the date hereof
     (the "OFFERING MEMORANDUM") setting forth information concerning the
     Company, the Guarantors, the Securities, the Common Stock and the
     Registration Rights Agreement, in each case, in form and substance
     satisfactory to you. Copies of the Preliminary Offering Memorandum have
     been, and copies of the Offering Memorandum will be, delivered by the
     Company to the Initial Purchasers pursuant to the terms of this Agreement.
     As used in this Agreement, "PRELIMINARY OFFERING MEMORANDUM" or "OFFERING
     MEMORANDUM" means the Preliminary Memorandum or Offering Memorandum, as the
     case may be, including the Incorporated Documents (as described below) as
     amended or supplemented. Each of the Preliminary Offering Memorandum and
     the Offering Memorandum, will not as of its respective date, and the
     Offering Memorandum will not as of any Delivery Date (as defined in Section
     2(b)), contain any untrue statement of a material fact or omit to state a
     material fact necessary in order to make the statements therein, in the
     light of the circumstances under which they were made, not misleading;
     provided that, the Company and the Guarantors make no representation or
     warranty as to information contained in or omitted from the Preliminary
     Offering Memorandum or the Offering Memorandum in reliance upon and in
     conformity with the written information furnished to the Company by or on
     the behalf of the Initial Purchasers specifically for inclusion therein.

          (b)  The documents deemed incorporated by reference in the Offering
     Memorandum which are listed under the heading "Incorporation of Certain
     Documents by Reference" in the Offering Memorandum (the "INCORPORATED
     DOCUMENTS"), when they became effective or were filed with the Commission,
     as the case may be, conformed in all

                                       2
<PAGE>

     material respects to the requirements of the Securities Exchange Act of
     1934, as amended, and the rules and regulations thereunder (collectively,
     the "EXCHANGE ACT"), and none of such documents contained any untrue
     statement of a material fact or omitted to state any material fact required
     to be stated therein or necessary to make the statements therein not
     misleading; and any further documents so filed and incorporated by
     reference in the Offering Memorandum, when such documents are filed with
     Commission will conform in all material respects to the requirements of the
     Exchange Act and 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 light of the circumstances in
     which they were made, not misleading.

          (c) Assuming the accuracy of the representations and warranties of the
     Initial Purchasers contained in Section 6 and their compliance with the
     agreements set forth therein, it is not necessary, in connection with the
     issuance and sale of the Securities to the Initial Purchasers, the offer,
     resale and delivery of the Securities by the Initial Purchasers and the
     conversion of the Securities into Conversion Shares, in each case in the
     manner contemplated by this Agreement, the Indenture, the Registration
     Rights Agreement and the Offering Memorandum, to register the Securities or
     the Conversion Shares under the Securities Act or to qualify the Indenture
     under the Trust Indenture Act of 1939, as amended, and the rules and
     regulations of the Commission thereunder (collectively, the "TRUST
     INDENTURE ACT").

          (d) There is no relationship, direct or indirect, between or among the
     Company and the Guarantors, on the one hand, and the directors, executive
     officers, shareholders, customers or suppliers of the Company or the
     Guarantors, on the other hand, as required to be described under Item 404
     of Regulation S-K under the Securities Act.

          (e) KPMG LLP (the "ACCOUNTANTS") are independent public accountants
     with respect to the Company and its subsidiaries as required by the
     Securities Act.

          (f) Neither the Company nor any of its subsidiaries has sustained,
     since the date of the latest audited financial statements included in the
     Offering Memorandum, any material loss or interference with its business
     from fire, explosion, flood or other calamity, whether or not covered by
     insurance, or from any labor dispute or court or governmental action, order
     or decree (a "MATERIAL LOSS"), otherwise than as set forth or contemplated
     in the Offering Memorandum; and, since such date, there has not been any
     change in the capital stock, short-term debt or long-term debt of the
     Company or any of its subsidiaries or any material adverse change, or any
     development involving a prospective material adverse change, in or
     affecting the general affairs, management, consolidated financial position,
     stockholders' equity, results of operations, business or prospects of the
     Company and its subsidiaries, otherwise than as set forth or contemplated
     in the Offering Memorandum.

          (g) The consolidated financial statements included in the Preliminary
     Offering Memorandum and Offering Memorandum (and any amendment or
     supplement thereto), together with related schedules and notes, present
     fairly the consolidated financial position, results of operations and
     changes in financial position of the Company and its subsidiaries on the
     basis stated therein at the respective dates or for the respective periods
     to which they apply; such statements and related schedules and notes have
     been prepared in accordance

                                       3
<PAGE>

     with generally accepted accounting principles consistently applied
     throughout the periods involved; the supporting schedules, if any, included
     in the Preliminary Offering Memorandum or the Offering Memorandum present
     fairly in accordance with generally accepted accounting principles the
     information required to be stated therein; and the other financial and
     statistical information and data set forth in the Preliminary Offering
     Memorandum and Offering Memorandum (and any amendment or supplement
     thereto) are, in all material respects, accurately presented and prepared
     on a basis consistent with such financial statements and the books and
     records of the Company.

     jurisdiction of incorporation and have the corporate power and authority to
     carry on their respective businesses as described in the Offering
     Memorandum and to own, lease and operate their respective properties, and
     each is duly qualified and is in good standing as a foreign corporation
     authorized to do business in each jurisdiction in which the nature of its
     business or its ownership or leasing of property requires such
     qualification, except where the failure to be so qualified would not have a
     material adverse effect on the business, prospects, financial condition or
     results of operations of the Company and its subsidiaries taken as a whole
     (a "MATERIAL ADVERSE EFFECT").

          (i) The Company has an authorized capitalization as set forth in the

     interest in its joint venture with Kimble Glass, Inc. and owns a 58%
     interest in Erie-Watala Glass Company Limited, its joint venture in Hong

     Securities, the compliance by the Company and the Guarantors with all the

     or assets of the Company or any of its subsidiaries is the subject which,

     no such proceedings are threatened or contemplated by governmental
     authorities or threatened by others.

          (x) No material labor disturbance by or dispute with the employees of

     with respect to termination of, or withdrawal from, any "pension plan" or
     (ii) Sections 412 or 4971 of the Internal Revenue Code of 1986, as amended,
     including the regulations and published interpretations thereunder
     (collectively, the "INTERNAL REVENUE CODE"); and each "pension plan" for
     which the Company would have any liability that is intended to be qualified
     under Section 401(a) of the Internal Revenue Code is so qualified in all
     material respects and nothing has occurred, whether by action or by failure
     to act, which would cause the loss of such qualification.

     Company and any person granting such person the right to require the
     Company to file a registration statement under the Securities Act with
     respect to any securities of the Company owned or to be owned by such

          (a) Subject to the terms and conditions and in reliance upon the
representations and warranties herein set forth, the Company agrees to sell to
each Initial Purchaser, and each Initial Purchaser agrees, severally and not
jointly, to purchase from the Company, at a purchase price of 97.5% of the
principal amount thereof (the "purchase price") of the Firm Securities set forth
opposite such Initial Purchaser's name in Schedule I hereto.

          Delivery of and payment for the Firm Securities shall be made at the
office of Simpson Thacher & Bartlett, 425 Lexington Avenue, New York, New York
10017, at 10:00 a.m. (New York City time) on October 10, 2001, or such later
date as the Initial Purchasers shall designate, which date and time may be
postponed by agreement between the Initial Purchasers and the Company (such date

"FIRST DELIVERY DATE").  Delivery of the Firm Securities shall be made to the
Initial Purchasers against payment of the purchase price by the Initial
Purchasers.  Payment for the Firm Securities shall be made against delivery to
the Initial Purchasers of the Firm Securities as described below and effected
either by wire transfer of immediately available funds to an account with a bank
in The City of New York, the account number and the ABA number for such bank to

Option to the Initial Purchasers to purchase, severally and not jointly, the
Option Securities at the same purchase price as the Initial Purchasers shall pay

sold to each Initial Purchaser shall be that principal amount which bears the
same ratio to the aggregate principal amount of Option Securities being
purchased as the principal amount of Firm Securities set forth opposite the name
of the Initial Purchaser in Schedule I hereto (or such number increased as set
forth in Section 8). The Option may be exercised in whole or in part at any time
and from time to time and the Company shall deliver such Option Securities not
more than 13 days subsequent to the First Delivery Date upon notice in writing
or by facsimile by Lehman Brothers Inc., on behalf of itself and the other
Initial Purchasers, to the Company setting forth the amount (which shall be an
integral multiple of $1,000 principal amount) of Option Securities as to which
such Option is being exercised.

          The date for the delivery of and payment for the Option Securities,
being herein referred to as an "OPTION DELIVERY DATE", which may be the First
Delivery Date (the First
                                       10

be agreed by the Company and the Initial Purchasers.

     Securities initially sold to qualified institutional buyers ("QIBS"), as
     defined in Rule 144A under the Securities Act ("RULE 144A"), in the form of
     one or more permanent global certificates (the "GLOBAL SECURITIES"),
     registered in the name of Cede & Co., as nominee for The Depository Trust
     Company ("DTC").  Beneficial interests in the Securities initially sold to
     QIBs will be shown on, and transfers thereof will be effected only through,
     records maintained in book-entry form by DTC and its participants.

           The Global Securities will be made available, at the request of any
  Initial Purchaser, for checking at least 24 hours prior to such Delivery Date.
  The Certificated Securities will be made available, at the request of the
  Initial Purchasers, for checking at least 48 hours prior to such Delivery
  Date.

     Purchasers, any event shall occur or condition exist as a result of which
     it is necessary to amend or supplement the Offering Memorandum in order
     that the Offering Memorandum will not include an untrue statement of a
     material fact or omit to state a material fact necessary in order to make
     the statements therein, in the light of the circumstances existing at the
     time it is delivered to a purchaser, not misleading, to promptly notify the
     Initial Purchasers and prepare, subject to the first sentence of this
     Section 3(a), such amendment or supplement as may be necessary to correct
     such untrue statement or omission.

     quantities as the Initial Purchasers reasonably request for internal use

     jurisdictions as the Initial Purchasers may request and to comply with such
     laws so as to permit the continuance of sales and dealings therein in such
     jurisdictions in the United States for as long as may be necessary to
     complete the resale of the Securities; provided that in connection
     therewith, the Company shall not be required to qualify as a foreign
     corporation or otherwise subject itself to taxation in any jurisdiction in
     which it is not otherwise so qualified or subject.

         or constitute a default under, any indenture, mortgage, deed of trust,
         loan agreement or other agreement or instrument known to such counsel
         to which the Company or any of the Guarantors is a party or by which
         the Company or the Guarantors are bound or to which any of the property
         or assets of the Company or the Guarantors are subject.

In rendering such opinion, such counsel may state that its opinion is limited to
matters governed by the federal laws of the United States of America, the laws
of the State of Wisconsin and the Wisconsin Business Corporation Law and may
state that it is relying, in respect of matters of New York law, upon Simpson
Thacher & Bartlett, and in respect of matters of fact, upon certificates of
officers of the Company, provided that such counsel shall state that it believes
that the Initial Purchasers and it are justified in relying upon such
certificates.  Such counsel shall also have furnished to the Initial Purchasers
a written statement, addressed to the Initial Purchasers and dated such Delivery
Date, in form and substance satisfactory to the Initial Purchasers, to the
effect that during the course of preparing the Offering Memorandum, such counsel
participated in conferences with officers and other representatives of the
Company, the Company's independent public accountants, the Initial Purchasers
and their counsel, at which the contents of the Offering Memorandum (including
the Incorporated Documents) were discussed, and while such counsel has not
independently verified and is not passing upon the accuracy, completeness or
fairness of the statements made in the Offering Memorandum (including the
Incorporated Documents) except as explicitly set forth above, no facts have come
to the attention of such counsel which lead it to believe that the Offering
Memorandum (including the Incorporated Documents), as of its date or as of such
Delivery Date, contained or contains any untrue statement of a material fact or
omitted or omits to state a material fact necessary in order

                                       18
<PAGE>

to make the statements therein, in light of the circumstances under which they
were made, not misleading, except that such counsel need express no belief as to
the financial statements, financial and statistical data and supporting
schedules contained in the Offering Memorandum (or in any Incorporated
Documents).

          (d) Simpson Thacher & Bartlett, shall have furnished to the Initial
     Purchasers its written opinion, as counsel to the Initial Purchasers,

     accountants within the meaning of the Securities Act and are in compliance

     financial information is given in the Offering Memorandum, as of a date not
     more than five days prior to the date hereof), the conclusions and findings
     of such firm with respect to the financial information and other matters
     ordinarily covered by accountants' "comfort letters" to initial purchasers
     in connection with comparable private placements, in form and substance
     satisfactory to the Initial Purchasers; and with respect to the Option
     Delivery Date, the Company shall have furnished to the Initial Purchasers
     the letter (the "bring-down letter") of such accountants, addressed to the
     Initial Purchasers and dated such Delivery Date (i) confirming that they
     are independent public accountants within the meaning of the Securities Act
     and are in compliance with the applicable requirements relating to the
     qualification of accountants under Rule 2-01 of Regulation S-X of the
     Commission, (ii) stating, as of the date of the bring-down letter (or, with
     respect to matters involving changes or developments since the respective
     dates as of which specified financial information is given in the Offering
     Memorandum, as of a date not more than five days prior to the date of the
     bring-down letter), the conclusions and findings of such firm with respect
     to the financial information and other matters covered by the initial

     applicable Delivery Date a certificate, dated such Delivery Date and
     delivered on behalf of the Company by its chief executive officer and its
     chief financial officer, in form and substance satisfactory to the Initial

        and each of the Guarantors in Section 1 are true and correct as of the
        date given and as of such Delivery Date; and the Company and the

         therein, in the light of the circumstances under which they were made,
         not misleading, and (B) since the date of the Offering Memorandum, no

     action arising out of or based upon matters covered by clause (i) or (ii)
     above (provided that the Company and the Guarantors shall not be liable
     under this clause (iii) to the extent that it is determined in a final
     judgment by a court of competent jurisdiction that such loss, claim,
     damage, liability or action resulted directly from any such acts or failure
     to act undertaken or omitted to be taken by such Initial Purchaser through
     its gross negligence or willful misconduct); and shall reimburse each
     Initial Purchaser and each such director, officer, employee and controlling
     person promptly upon demand for any legal or other expenses reasonably
     incurred by that Initial Purchaser, director, officer, employee or

     claim, damage, liability or action arises out of, or is based upon, any
     untrue statement or alleged untrue statement or omission or alleged
     omission made in any Preliminary Offering Memorandum or the Offering
     Memorandum, or in any such amendment or supplement, in reliance upon and in
     conformity with the written information concerning such Initial Purchaser
     furnished to the Company by or on behalf of that Initial Purchaser
     concerning the Initial Purchasers specifically for inclusion therein which
     information consists solely of the information set forth in the letter
     referred to in Section 7(e). The foregoing indemnity agreement is in

     liability, joint or several, or any action in respect thereof, to which the
     Company, the Guarantors or any their respective director, officer or
     controlling person may become subject, under the Securities Act or
     otherwise, insofar as such loss, claim, damage, liability or action arises
     out of, or is based upon, (i) any untrue statement or alleged untrue
     statement of a material fact contained in any Preliminary Offering
     Memorandum or the Offering Memorandum or in any amendment or supplement
     thereto, or in any Blue Sky Application, or (ii) the omission or alleged
     omission to state in any Preliminary Offering Memorandum or the Offering
     Memorandum or in any amendment or supplement thereto or in any Blue Sky
     Application, any material fact necessary to make the statements therein not
     misleading, but in each case only to the extent that the untrue statement
     or alleged untrue statement or omission or alleged omission was made in
     reliance upon and in conformity with the written information furnished to
     the Company by or on behalf of that Initial Purchaser specifically for
     inclusion therein and described in Section 7(e), and shall reimburse the
     Company, the Guarantors and any of their respective directors, officers or
     controlling persons promptly upon demand for any legal or other expenses
     reasonably incurred by the Company, the Guarantors or any of their
     respective directors, officers or controlling persons in connection with
     investigating or defending or preparing to defend against any such loss,

          (c) Promptly after receipt by an indemnified party under this Section
     7 of notice of any claim or the commencement of any action, the indemnified
     party shall, if a claim in respect thereof is to be made against the
     indemnifying party under this Section 7, notify the indemnifying party in
     writing of the claim or the commencement of that action; provided, however,
     that the failure to notify the indemnifying party shall not relieve it from
     any liability which it may have under this Section 7 except to the extent
     it has been materially prejudiced by such failure and, provided, further,
     that the failure to notify the indemnifying party shall not relieve it from
     any liability which it may have to an indemnified

                                       23
<PAGE>

     party otherwise than under this Section 7. If any such claim or action
     shall be brought against an indemnified party, and it shall notify the
     indemnifying party thereof, the indemnifying party shall be entitled to
     participate therein and, to the extent that it wishes, jointly with any
     other similarly notified indemnifying party, to assume the defense thereof
     with counsel satisfactory to the indemnified party. After notice from the
     indemnifying party to the indemnified party of its election to assume the
     defense of such claim or action, the indemnifying party shall not be liable
     to the indemnified party under this Section 7 for any legal or other
     expenses subsequently incurred by the indemnified party in connection with
     the defense thereof other than reasonable costs of investigation; provided,
     however, that the Initial Purchasers shall have the right to employ
     separate counsel to represent jointly the Initial Purchasers and their
     respective directors, officers, employees and controlling persons who may
     be subject to liability arising out of any claim in respect of which
     indemnity may be sought by the Initial Purchasers against the Company under
     this Section 7 if, in the reasonable judgment the Initial Purchasers it is
     advisable for the Initial Purchasers and such directors, officers,
     employees and controlling persons to be jointly represented by separate
     counsel, and in that event the fees and expenses of such separate counsel
     shall be paid by the Company and the Guarantors. No indemnifying party
     shall, (i) without the prior written consent of the indemnified parties
     (which consent shall not be unreasonably withheld) settle or compromise or
     consent to the entry of any judgment with respect to any pending or
     threatened claim, action, suit or proceeding in respect of which
     indemnification or contribution may be sought hereunder (whether or not the
     indemnified parties are actual or potential parties to such claim or
     action) unless such settlement, compromise or consent includes an
     unconditional release of each indemnified party from all liability arising
     out of such claim, action, suit or proceeding, or (ii) be liable for any
     settlement of any such action effected without its written consent (which
     consent shall not be unreasonably withheld), but if settled with its
     written consent or if there be a final judgment of the plaintiff in any
     such action, the indemnifying party agrees to indemnify and hold harmless
     any indemnified party from and against any loss or liability by reason of
     such settlement or judgment.

          (d) If the indemnification provided for in this Section 7 shall for
     any reason be unavailable or insufficient to hold harmless an indemnified
     party under Section 7(a) or 7(b) in respect of any loss, claim, damage or
     liability, or any action in respect thereof, referred to therein, then each
     indemnifying party shall, in lieu of indemnifying such indemnified party,
     contribute to the amount paid or payable by such indemnified party as a
     result of such loss, claim, damage or liability, or action in respect
     thereof, (i) in such proportion as shall be appropriate to reflect the
     relative benefits received by the Company and the Guarantors on the one
     hand and the Initial Purchasers on the other from the offering of the
     Securities, or (ii) if the allocation provided by clause 7(d)(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 7(d)(i) but
     also the relative fault of the Company and the Guarantors on the one hand
     and the Initial Purchasers on the other with respect to the statements or
     omissions or alleged statements or alleged omissions that resulted in such
     loss, claim, damage or liability (or action in respect thereof), as well as
     any other relevant equitable considerations. The relative benefits received
     by the Company and the Guarantors on the one hand and the Initial
     Purchasers on the other with respect to such offering shall be deemed to be
     in the same proportion as the total net proceeds from the offering of the
     Securities purchased under this Agreement (before deducting expenses)
     received by the Company and the Guarantors on the

                                       24
<PAGE>

     one hand, and the total discounts and commissions received by the Initial
     Purchasers with respect to the Securities purchased under this Agreement,
     on the other hand, bear to the total gross proceeds from the offering of
     the Securities under this Agreement. The relative fault shall be determined
     by reference to 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 the Company, the Guarantors or the
     Initial Purchasers, the intent of the parties and their relative knowledge,
     access to information and opportunity to correct or prevent such statement
     or omission. The Company, the Guarantors and the Initial Purchasers agree
     that it would not be just and equitable if the amount of contributions
     pursuant to this Section 7(d) were to be determined by pro rata allocation
     or by any other method of allocation which does not take into account the
     equitable considerations referred to herein. The amount paid or payable by
     an indemnified party as a result of the loss, claim, damage or liability,
     or action in respect thereof, referred to above in this Section 7(d) shall
     be deemed to include, for purposes of this Section 7(d), any legal or other
     expenses reasonably incurred by such indemnified party in connection with
     investigating or defending any such action or claim. Notwithstanding the
     provisions of this Section 7(d), no Initial Purchaser shall be required to
     contribute any amount in excess of the amount by which the total price at
     which the Securities resold by it in the initial placement of such
     Securities were offered to investors exceeds the amount of any damages
     which such Initial Purchaser has otherwise paid or become liable by reason
     of any 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
     Initial Purchasers' obligations to contribute as provided in this Section
     7(d) are several in proportion to their respective obligations, not joint.

          (e) The Initial Purchasers confirm and the Company acknowledges that
     the statements with respect to the offering of the Securities by the
     Initial Purchasers set forth in the sixth paragraph, the fourth sentence of
     the eighth paragraph and the tenth paragraph under the caption "Plan of
     Distribution" in the Offering Memorandum constitute the only information
     concerning the Initial Purchasers furnished in writing to the Company by or
     on behalf of the Initial Purchasers specifically for inclusion in the
     Offering Memorandum. Credit Suisse First Boston Corporation and Banc of
     America Securities LLC confirm and the Company acknowledges that the
     statements by them set forth in the last paragraph under the caption "Plan
     of Distribution" in the Offering Memorandum constitute the only information
     concerning them furnished in writing to the Company by them or on their
     behalf specifically for inclusion in the Offering Memorandum.

          8. Defaulting Initial Purchasers. If, on any Delivery Date, any
Initial Purchaser defaults in the performance of its obligations under this
Agreement, the remaining non-defaulting Initial Purchasers shall be obligated to
purchase the aggregate principal amount of Securities which the defaulting
Initial Purchaser agreed but failed to purchase on such Delivery Date in the
respective proportions which the total aggregate principal amount of Securities
set opposite the name of each remaining non-defaulting Initial Purchaser in
Schedule I hereto bears to the total aggregate principal amount of Securities
set opposite the names of all the remaining non-defaulting Initial Purchasers in
Schedule I hereto; provided, however, that the remaining non-defaulting Initial
Purchasers shall not be obligated to purchase any Securities on such

                                       25
<PAGE>

Delivery Date if the total aggregate principal amount of Securities which the
defaulting Initial Purchasers agreed but failed to purchase on such date exceeds
9.09% of the total aggregate principal amount of Securities to be purchased on
such Delivery Date, and any remaining non-defaulting Initial Purchaser shall not
be obligated to purchase more than 110% of the aggregate principal amount of
Securities which it agreed to purchase on such Delivery Date pursuant to the
terms of Section 2. If the foregoing maximums are exceeded, the remaining non-
defaulting Initial Purchasers, or those other purchasers satisfactory to the
Initial Purchasers who so agree, shall have the right, but shall not be
obligated, to purchase on such Delivery Date, in such proportion as may be
agreed upon among them, the total aggregate principal amount of Securities to be
purchased on such Delivery Date. If the remaining Initial Purchasers or other
purchasers satisfactory to the Initial Purchasers do not elect to purchase on
such Delivery Date the aggregate principal amount of Securities which the
defaulting Initial Purchasers agreed but failed to purchase, this Agreement (or
with respect to the Option Delivery Date, the obligation of the Initial
Purchasers to purchase the Option Securities) shall terminate without liability
on the part of any non-defaulting Initial Purchasers and the Company, except
that the Company will continue to be liable for the payment of expenses to the
extent set forth in Sections 4 and 10. As used in this Agreement, the term
"INITIAL PURCHASER" includes, for all purposes of this Agreement unless the
context requires otherwise, any party not listed in Schedule I hereto who,
pursuant to this Section 8, purchases Securities which a defaulting Initial
Purchaser agreed but failed to purchase.

          Nothing contained herein shall relieve a defaulting Initial Purchaser
of any liability it may have to the Company for damages caused by its default.
If other purchasers are obligated or agree to purchase the Securities of a
defaulting or withdrawing Initial Purchaser, either the remaining non-defaulting
Initial Purchasers or the Company may postpone the Delivery Date for up to seven
full business days in order to effect any changes in the Offering Memorandum or
in any other document or arrangement that, in the opinion of counsel to the
Company or counsel to the Initial Purchasers, may be necessary.

          9. Termination. The obligations of the Initial Purchasers hereunder
may be terminated by the Initial Purchasers by notice given to and received by
the Company prior to delivery of and payment for the Securities if, prior to
that time, any of the events described in Sections 5(l), 5(m) or 5(n) shall have
occurred or if the Initial Purchasers shall decline to purchase the Firm
Securities for any reason permitted under this Agreement.

          10. Reimbursement of Initial Purchasers' Expenses. If (a) the
Company and the Guarantors shall fail to tender the Securities for delivery to
the Initial Purchasers for reason of any failure, refusal or inability on the
part of the Company and the Guarantor to perform any agreement on their part to
be performed, or because any other condition of the Initial Purchasers'
obligations hereunder required to be fulfilled by the Company and the Guarantor
(including, without limitation, with respect to the transactions) is not
fulfilled or (b) the Initial Purchasers shall decline to purchase the Securities
for any reason permitted under this Agreement (including the termination of this
Agreement pursuant to Section 9), the Company and the Guarantors shall reimburse
the Initial Purchasers for the reasonable fees and expenses of their counsel and
for such other out-of-pocket expenses including reasonable fees and
disbursements incurred by them in connection with this Agreement and the
proposed purchase of the Securities, and upon demand the Company and the
Guarantors shall pay the full amount thereof to the Initial

                                       26
<PAGE>

Purchasers. If this Agreement is terminated pursuant to Section 8 by reason of
the default of one or more Initial Purchasers, the Company shall not be
obligated to reimburse any defaulting Initial Purchasers on account of those
expenses.

          11. Notices, etc. All statements, requests, notices and agreements
hereunder shall be in writing, and:

          (a) if to the Initial Purchasers, shall be delivered or sent by mail,

UBS WARBURG LLC

c/o Lehman Brothers Inc.
101 Hudson Street
Jersey City, New Jersey 07302

Dear Ladies and Gentlemen:

     The undersigned understands that you propose to enter into a Purchase
Agreement (the "Purchase Agreement") providing for the purchase by you (the
"Initial Purchasers") of 2.25% Senior Convertible Contingent Debt Securities
(the "CODES") due 2021 of Apogent Technologies, Inc., a Wisconsin corporation
(the "Company"), which are convertible into fully paid, nonassessable shares of
common stock of the Company, par value $0.01 per share (the "Common Stock"), and
that the Initial Purchasers propose to reoffer the CODES (the "Offering").

     In consideration of the execution of the Purchase Agreement by the Initial
Purchasers, and for other good and valuable consideration, the undersigned
hereby irrevocably agrees that, without the prior written consent of Lehman
Brothers Inc., the undersigned will not, directly or indirectly, (1) offer for
sale, sell, pledge or otherwise dispose of (or enter into any transaction or
device which is designed to, or could be expected to, result in the disposition
by any person at any time in the future of) any debt securities of the Company
(other than the CODES), shares of Common Stock or securities convertible into or
exchangeable for Common Stock, or sell or grant options, rights or warrants with
respect to any debt securities, shares of Common Stock or securities convertible
into or exchangeable for Common Stock, or (2) enter into any swap or other
derivatives transaction that transfers to another, in whole or in part, any of
the economic benefits or risks of ownership of such securities, such shares of
Common Stock, whether any such transaction described in clause (1) or (2) above
is to be settled by delivery of Common Stock or other securities, in cash or
otherwise, for a period of 90 days after the date of the final Offering
Memorandum relating to the Offering, but in no event shall the period of
restriction be effective beyond January 25, 2002.

     In furtherance of the foregoing, the Company and its Transfer Agent are
hereby authorized to decline to make any transfer of securities if such transfer
would constitute a violation or breach of this Lock-Up Letter Agreement.

                                       33
<PAGE>

     Notwithstanding the foregoing, the undersigned may transfer Common Stock or
securities convertible into or exchangeable for Common Stock, including options
therefore (collectively, the "Shares") (1) as a bona fide gift or gifts,
provided that the donee or donees thereof agree to be bound in writing by
restrictions set forth herein, or (2) to any trust for the direct or indirect
benefit of the undersigned or the immediate family of the undersigned provided
that the trustee of the trust agrees to be bound in writing by the restrictions
set forth herein, and provided further that any such transfer shall not involve
a disposition for.

     The undersigned understands that the Company and the Initial Purchasers
will proceed with the Offering in reliance on this Lock-Up Letter Agreement.
Whether or not the Offering actually occurs depends on a number of factors,
including market conditions. Any Offering will only be made pursuant to a
Purchase Agreement, the terms of which are subject to negotiation between the
Company and the Initial Purchasers.

     It is understood that, if the Company notifies you that it does not intend
to proceed with the Offering, if the Purchase Agreement does not become
effective, or if the Purchase Agreement (other than the provisions thereof which
survive termination) shall terminate or be terminated prior to payment for and
delivery of the CODES, we will be released from our obligations under this Lock-
Up Letter Agreement.

     This Agreement shall be governed by, and construed in accordance with, the
laws of New York.

     The undersigned hereby represents and warrants that the undersigned has
full power and authority to enter into this Lock-Up Letter Agreement and that,
upon request, the undersigned will execute any additional documents necessary in
connection with the enforcement hereof.  Any obligations of the undersigned

                   (x) with respect to the first 90-day period during which a
                   Registration Default shall have occurred and be continuing,
                   equal to 0.25% per annum of the principal amount of

<PAGE>

                   the CODES, and (y) with respect to the period commencing on

                   have occurred and be continuing, equal to 0.50% per annum of
                   the principal amount of the CODES; provided that in no event
                   shall Additional Amounts accrue at a rate per year exceeding
                   0.50% of the principal amount of the CODES; and

                        (B)  in respect of any shares of Common Stock, to each
                   holder of shares of Common Stock issued upon conversion of
                   the CODES, (x) with respect to the first 90-day period in
                   which a Registration Default shall have occurred and be
                   continuing, equal to 0.25% per annum of the principal amount
                   of the converted CODES, and (y) with respect to the period
                   commencing the 91st day following the day the Registration
                   Default shall have occurred and be continuing, equal to 0.50%
                   per annum of the principal amount of the converted CODES;
                   provided that in no event shall Additional Amounts accrue at
                   a rate per year exceeding 0.50% of the principal amount of
                   the converted CODES.

         Record Holders by the Issuer or the Guarantors on each Additional

         to such CODES or share of Common Stock will cease. The Issuer and the
         Guarantors agree to deliver all notices, certificates and other
         documents contemplated by the Indenture in connection with the payment
         of Additional Amounts.

remedy available to the Holders of Transfer Restricted Securities for such
Registration Default.

                                       7

         described in Section 4(b)(iv)(E), keep the Shelf Registration
         Statements continuously effective during the Effectiveness Period; upon
         the occurrence of any event that would cause any Shelf Registration
         Statement or the Prospectus contained therein (A) to contain a material
         misstatement or omission or (B) not be effective and usable for resale
         of Transfer Restricted Securities during the Effectiveness Period, the
         Issuer shall file promptly an appropriate amendment to the Shelf
         Registration Statement, a supplement to the Prospectus or a report
         filed with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d)
         of the Exchange Act, in the case of clause (A), correcting any such
         misstatement or omission, and, in the case of either clause (A) or (B),
         cause such amendment to be declared effective and the Shelf
         Registration Statement and the related Prospectus to become usable for
         their intended purposes as soon as practicable thereafter.
         Notwithstanding the foregoing, the Issuer or the Guarantors may suspend
         the effectiveness of any Shelf Registration Statement by written notice
         to the Holders for a period not to exceed an aggregate of 45 days in
         any 90-day period (each such period, a "SUSPENSION PERIOD") if:

                    (x)  an event occurs and is continuing as a result of which
               the Shelf Registration Statement would, in the Issuer's judgment,
               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

                    (y)  the Issuer reasonably determines that the disclosure
               of such event at such time would have a material adverse effect
               on the business of the Issuer and its subsidiaries taken as a
               whole;

         provided that in the event the disclosure relates to a previously
         undisclosed proposed or pending material business transaction, the
         disclosure of which would impede the Issuer's ability to consummate
         such transaction, the Issuer may extend a Suspension Period from 45
         days to 60 days; provided, however, that Suspension Periods shall not
         exceed an aggregate of 90 days in any 360-day period.

              (ii)  Prepare and file with the Commission such amendments and
         post-effective amendments to the Shelf Registration Statements as may
         be necessary to keep the Shelf Registration Statements effective during
         the Effectiveness Period; cause the Prospectuses to be supplemented by
         any required Prospectus supplement, and as so supplemented to be filed
         pursuant to Rule 424 under the Securities Act, and to comply fully with
         the applicable provisions of Rules 424 and 430A under the Securities
         Act in a timely manner; and comply with the provisions of the
         Securities Act with respect to the disposition of all securities
         covered by the Shelf Registration Statements during the applicable
         period in accordance with the intended method or methods of
         distribution by the sellers thereof set forth in the Shelf Registration
         Statements or supplement to the Prospectuses.

                                       8

              (iii)  Cause any Person that becomes a Guarantor on any Roll-up
         Date to promptly execute and deliver an acknowledgement pursuant to
         Section 13.5 of the Indenture acknowledging that such Person shall
         become a party to this Agreement; the form of such acknowledgment is
         attached hereto as Exhibit B.

              (iv)  Advise the Underwriter(s), if any, and Selling Holders
         promptly (but in any event within five Business Days) and, if requested
         by such Persons, to confirm such advice in writing:

                   (A)  when any Prospectus or any Prospectus supplement or
              post-effective amendment has been filed, and, with respect to any
              Shelf Registration Statement or any post-effective amendment
              thereto, when the same has become effective,

                   (B)  of any request by the Commission for amendments to any
              Shelf Registration Statement or amendments or supplements to any
              Prospectus or for additional information relating thereto,

                   (C)  of the issuance by the Commission of any stop order
              suspending the effectiveness of any Shelf Registration Statement
              under the Securities Act or of the suspension by any state
              securities commission of the qualification of the Transfer
              Restricted Securities for offering or sale in any jurisdiction, or
              the initiation of any proceeding for any of the preceding
              purposes,

                   (D)  of the commencement of any Suspension Period, or

                   (E)  of the existence of any fact or the happening of any
              event, during the Effectiveness Period, that makes any statement
              of a material fact made in any Shelf Registration Statement, the
              Prospectus contained therein, any amendment or supplement thereto,
              or any document incorporated by reference therein untrue, or that
              requires the making of any additions to or changes in the Shelf
              Registration Statement or the Prospectus in order to make the
              statements therein not misleading.

         If at any time the Commission shall issue any stop order suspending
         the effectiveness of any Shelf Registration Statement, or any state
         securities commission or other regulatory authority shall issue an
         order suspending the qualification or exemption from qualification of
         the Transfer Restricted Securities under state securities or Blue Sky
         laws, the Issuer and the Guarantors shall obtain the withdrawal or
         lifting of such order at the earliest possible time and will provide
         to the Initial Purchasers and each Holder who is named in the Shelf
         Registration Statement prompt notice of the withdrawal of any such
         order.

              (v) Furnish to each of the Selling Holders and each of the
         Underwriter(s), if any, before filing with the Commission, a copy of
         each Shelf Registration Statement and copies of any Prospectus included
         therein or any amendments or supplements to the Shelf Registration
         Statement or Prospectus

                                       9
<PAGE>

         (other than documents incorporated by reference after the initial
         filing of the Shelf Registration Statement), which documents will be
         subject to the review of such Selling Holders and Underwriter(s), if
         any, for a period of at least ten Business Days (in the case of the
         Shelf Registration Statement and Prospectus) and two Business Days (in
         the case of any amendment or supplement thereto), and neither the
         Issuer nor the Guarantors will file the Shelf Registration Statement or
         Prospectus or any amendment or supplement to the Shelf Registration
         Statement or Prospectus (other than documents incorporated by
         reference) to which a selling Holder of Transfer Restricted Securities
         covered by the Shelf Registration Statement or the Underwriter(s), if
         any, shall reasonably object prior to the filing thereof. A Selling
         Holder or Underwriter, if any, shall be deemed to have reasonably
         objected to such filing if the Shelf Registration Statement, amendment,
         Prospectus or supplement, as applicable, as proposed to be filed,
         contains a material misstatement or omission.

              (vi) Make available at reasonable times for inspection by one or
         more representatives of the Selling Holders, designated in writing by a
         Majority of Holders whose Transfer Restricted Securities are included
         in any Shelf Registration Statement, any Underwriter, and any attorney
         or accountant retained by such Selling Holders or any of the
         Underwriter(s), all financial and other records, pertinent corporate
         documents and properties of the Issuer and the Guarantors as shall be
         reasonably necessary to enable them to conduct a reasonable
         investigation within the meaning of Section 11 of the Securities and
         exercise any applicable due diligence responsibilities, and cause the
         Issuer's and the Guarantors' officers, directors, managers and
         employees to supply all information reasonably requested by any such
         representative or representatives of the Selling Holders, Underwriter,
         attorney or accountant in connection with the Shelf Registration
         Statement after the filing thereof and before its effectiveness,
         provided, however, that any information designated by the Issuer as
         confidential at the time of delivery of such information shall be kept
         confidential by the recipient thereof.

              (vii) If requested by any Selling Holder, promptly incorporate in
         each Shelf Registration Statement or Prospectus, pursuant to a
         supplement or post-effective amendment if necessary, such information
         as such Selling Holders and Underwriter(s), if any, may reasonably
         request to have included therein, including, without limitation: (1)
         information relating to the "Plan of Distribution" of the Transfer
         Restricted Securities, (2) information with respect to the principal
         amount of Securities or number of shares of Common Stock being sold to
         such Underwriter(s), (3) the purchase price being paid therefor and (4)
         any other terms of the offering of the Transfer Restricted Securities
         to be sold in such offering; and make all required filings of such
         Prospectus supplement or post-effective amendment as soon as reasonably
         practicable after the Issuer and the Guarantors are notified of the
         matters to be incorporated in such Prospectus supplement or post-
         effective amendment.

                                       10
<PAGE>

              (viii) Furnish to each Selling Holder and each of the
         Underwriter(s), if any, without charge, at least one copy of each Shelf
         Registration Statement, as first filed with the Commission, and of each
         amendment thereto (and any documents incorporated by reference therein
         or exhibits thereto (or exhibits incorporated in such exhibits by
         reference) as such Person may request). (ix) Deliver to each Selling
         Holder and each of the Underwriter(s), if any, without charge, as many
         copies of each Prospectus (including each preliminary Prospectus) and
         any amendment or supplement thereto as such Persons reasonably may
         request; subject to any notice by the Issuer in accordance with this
         Section 4(b) of the existence of any fact or event of the kind
         described in Section 4(b)(iv) (E), the Issuer and the Guarantors hereby
         consent to the use of each Prospectus and any amendment or supplement
         thereto by each of the Selling Holders and each of the Underwriter(s),
         if any, in connection with the offering and the sale of the Transfer
         Restricted Securities covered by the Prospectus or any amendment or
         supplement thereto.

              (ix) Deliver to each Selling Holder and each of the
         Underwriter(s), if any, without charge, as many copies of each
         Prospectus (including each preliminary Prospectus) and any amendment or
         supplement thereto as such Persons reasonably may request; subject to
         any notice by the Issuer in accordance with this Section 4(b) of the
         existence of any fact or event of the kind described in Section
         4(b)(iv) (E), the Issuer and the Guarantors hereby consent to the use
         of each Prospectus and any amendments or supplement thereto by each of
         the Selling Holders and each of the Underwriter(s), if any, in
         connection with the offering and the sale of the Transfer Restricted
         Securities covered by the Prospectus or any amendment or supplement
         thereto.

              (x)  The Issuer and the Guarantors shall:

                   (A) upon request, furnish to each Selling Holder and each
              underwriter, if any, in such substance and scope as they may
              reasonably request and as are customarily made by issuers to
              Underwriters in primary Underwritten Offerings for Selling
              Holders, upon the date of closing of any sale of Transfer
              Restricted Securities in an Underwritten Registration:

                         (1) a certificate, dated the date of such closing,
                    signed by the Chief Financial Officer of the Issuer and of
                    each of the Guarantors confirming, as of the date thereof,
                    the matters set forth in Section 5(f) of the Purchase
                    Agreement and such other matters as such parties may
                    reasonably request ;

                         (2) opinions, each dated the date of such closing, of
                    counsel to the Issuer and the Guarantors covering such of
                    the matters as are customarily covered in legal opinions to
                    Underwriters in connection with Underwritten Offerings of
                    securities; and

                         (3) customary comfort letters, dated the date of such
                    closing, from the Issuer's and the Guarantors' independent
                    accountants (and from any other accountants whose report is
                    contained or incorporated by reference in the Shelf
                    Registration Statements) in the customary form and covering
                    matters of the type customarily covered in comfort letters
                    to Underwriters in connection with Underwritten Offerings of
                    securities;

                    (B) set forth in full in the underwriting agreement, if any,
               indemnification provisions and procedures which provide rights no
               less protective than those set forth in Section 6 hereof with
               respect to all parties to be indemnified; and

                                       11
<PAGE>

                    (C) deliver such other documents and certificates as may be
               reasonably requested by such parties to evidence compliance with
               clause (A) above and with any customary conditions contained in
               the underwriting agreement or other agreement entered into by the
               Selling Holders pursuant to this clause (x).

               (xi) Before any public offering of Transfer Restricted
          Securities, cooperate with the Selling Holders, the Underwriter(s), if
          any, and their respective counsel in connection with the registration
          and qualification of the Transfer Restricted Securities under the
          securities or Blue Sky laws of such jurisdictions in the United States
          as the Selling Holders or Underwriter(s), if any, may reasonably
          request and do any and all other acts or things necessary or advisable
          to enable the disposition in such jurisdictions of the Transfer
          Restricted Securities covered by the Shelf Registration Statements;
          provided, however, that neither the Issuer nor any Guarantor shall be
          required (A) to register or qualify as a foreign corporation or a
          dealer of securities where it is not now so qualified or to take any
          action that would subject it to the service of process in any
          jurisdiction where it is not now so subject or (B) to subject itself
          to taxation in any such jurisdiction if it is not now so subject.

               (xii) Cooperate with the Selling Holders and the Underwriter(s),
          if any, to facilitate the timely preparation and delivery of
          certificates representing Transfer Restricted Securities to be sold
          and not bearing any restrictive legends (unless required by applicable
          securities laws); and enable such Transfer Restricted Securities to be
          in such denominations and registered in such names as the Holders or
          the Underwriter(s), if any, may request at least two Business Days
          before any sale of Transfer Restricted Securities made by such
          Underwriter(s).

               (xiii) Use their reasonable best efforts to cause the Transfer
          Restricted Securities covered by the Shelf Registration Statements to
          be registered with or approved by such other U.S. governmental
          agencies or authorities as may be necessary to enable the seller or
          sellers thereof or the Underwriter(s), if any, to consummate the
          disposition of such Transfer Restricted Securities.

               (xiv) Subject to Section 4(b)(i) hereof, if any fact or event
          contemplated by Section 4(b)(iv)(E) hereof shall exist or have
          occurred, use their reasonable best efforts to prepare a supplement or
          post-effective amendment to each Shelf Registration Statement or
          related Prospectus or any document incorporated therein by reference
          or file any other required document so that, as thereafter delivered
          to the purchasers of Transfer Restricted Securities, the Prospectus
          will not contain an 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 light of the circumstances in which
          they were made, not misleading.

               (xv) Provide CUSIP numbers for all Transfer Restricted Securities
          not later than the effective date of the Initial Shelf Registration
          Statement and provide the Trustee under the Indenture with
          certificates for the Securities that are in a form eligible for
          deposit with The Depository Trust Company.

                                       12
<PAGE>

               (xvi) Cooperate and assist in any filings required to be made
          with the NASD and in the performance of any due diligence
          investigation by any underwriter that is required to be retained in
          accordance with the rules and regulations of the NASD.

               (xvii) Otherwise use their reasonable best efforts to comply with
          all applicable rules and regulations of the Commission and all
          reporting requirements under the Exchange Act.

               (xviii) Cause the Indenture to be qualified under the TIA not
          later than the effective date of the Initial Shelf Registration
          Statement required by this Agreement, and, in connection therewith,
          cooperate with the Trustee and the holders of CODES to effect such
          changes to the Indenture as may be required for such Indenture to be
          so qualified in accordance with the terms of the TIA; and execute and
          use their reasonable best efforts to cause the Trustee thereunder to
          execute all documents that may be required to effect such changes and
          all other forms and documents required to be filed with the Commission
          to enable such Indenture to be so qualified in a timely manner.

               (xix) Cause all Transfer Restricted Securities covered by the
          Shelf Registration Statements to be listed or quoted, as the case may
          be, on each securities exchange or automated quotation system on which
          similar securities issued by the Issuer are then listed or quoted.

               (xx) Provide to each Holder upon written request each document
          filed with the Commission pursuant to the requirements of Section 13
          and Section 15 of the Exchange Act after the effective date of the
          Initial Shelf Registration Statement.

               (xxi) If requested by the Underwriters, make appropriate officers
          of the Issuer and the Guarantors available to the Underwriters for
          meetings with prospective purchasers of the Transfer Restricted
          Securities and prepare and present to potential investors customary
          "road show" or marketing materials in a manner consistent with other
          new issuances of other securities similar to the Transfer Restricted
          Securities.

          (c) Each Holder agrees by acquisition of a Transfer Restricted
     Security that, upon receipt of any notice (a "SUSPENSION NOTICE") from the
     Issuer of the existence of any fact of the kind described in Section
     4(b)(iv)(E) hereof, such Holder will, and will use its reasonable best
     efforts to cause any Underwriter(s) in an Underwritten Offering to,
     forthwith discontinue disposition of Transfer Restricted Securities
     pursuant to any Shelf Registration Statement until:

               (i) such Holder has received copies of the supplemented or
           amended Prospectus contemplated by Section 4(b)(xiv) hereof; or

               (ii) such Holder is advised in writing by the Issuer that the use
           of the Prospectus may be resumed, and has received copies of any
           additional or supplemental filings that are incorporated by reference
           in any Prospectus.

                                       13
<PAGE>

     If so directed by the Issuer, each Holder will deliver to the Issuer (at
     the Issuer's expense) all copies, other than permanent file copies then in
     such Holder's possession, of the Prospectus covering such Transfer
     Restricted Securities that was current at the time of receipt of such
     notice of suspension.

                (d) Each Holder who intends to be named as a Selling Holder in
           the Initial Shelf Registration Statement shall complete the
           Questionnaire and deliver it to the Issuer within 20 Business Days
           after receipt of a written request thereof (which request shall
           include a copy at the Questionnaire). Prior to such time, each Holder
           may complete the Questionnaire and deliver it to the Issuer prior to
           such request and, as a result, shall be entitled to have its Transfer
           Restricted Securities included in the Initial Shelf Registration
           Statement filed with the Commission. Holders that do not complete the
           Questionnaire and deliver it to the Issuer on a timely basis shall
           not be eligible to be named as Selling Holders in the Prospectus or
           preliminary Prospectus included in the Initial Shelf Registration
           Statement and, therefore, shall not be permitted to sell any Transfer
           Restricted Securities pursuant to the Shelf Registration Statements.
           In addition, each Holder who intends to be named as a Selling Holder
           in the Shelf Registration Statements shall promptly respond to the
           Issuer by providing such other information as the Issuer may from
           time to time reasonably request in writing regarding the Holder and
           the proposed distribution by such Holder of its Transfer Restricted
           Securities in connection with the Shelf Registration Statements or
           Prospectuses or preliminary Prospectuses included therein.

                (e) Upon the effectiveness of the Initial Shelf Registration
           Statement, each Holder shall notify the Issuer at least three
           Business Days prior to any intended distribution of Transfer
           Restricted Securities pursuant to the Shelf Registration Statements
           (a "SALE NOTICE"), which notice shall be effective for five Business
           Days. Each Holder of Transfer Restricted Securities, by accepting the
           same, agrees to hold any communication by the Issuer in response to a
           Sale Notice in confidence.

     5. REGISTRATION EXPENSES. All expenses incident to the Issuer's and the
Guarantors' performance of or compliance with this Agreement shall be borne by
the Issuer regardless of whether any Shelf Registration Statement becomes
effective, including, without limitation:

                (i) all registration and filing fees and expenses (including
           filings made by any Initial Purchaser or Holder with the NASD);

                (ii) all fees and expenses of compliance with federal securities
           and state Blue Sky or securities laws;

                (iii) all expenses of printing (including printing of
           Prospectuses and certificates for the Common Stock to be issued upon
           conversion of the CODES) and the Issuer's expenses for messenger and
           delivery services and telephone;

                (iv) all fees and disbursements of counsel to the Issuer and the
           Guarantors and, subject to Section 5(b) below, the Holders of
           Transfer Restricted Securities;

                                       14
<PAGE>

                (v) all application and filing fees in connection with listing
           (or authorizing for quotation) the Common Stock on a national
           securities exchange or automated quotation system pursuant to the
           requirements hereof; and

                (vi) all fees and disbursements of independent certified public
           accountants of the Issuer (including the expenses of any special
           audit and comfort letters required by or incident to such
           performance).

          The Issuer and the Guarantors shall bear their internal expenses
     (including, without limitation, all salaries and expenses of their
     respective officers and employees performing legal, accounting or other
     duties), the expenses of any annual audit and the fees and expenses of any
     Person, including special experts, retained by the Issuer and the
     Guarantors.

          (b) In connection with the Shelf Registration Statements required by
     this Agreement, including any amendment or supplement thereto, and any
     other documents delivered to any Holders, the Issuer shall reimburse the
     Initial Purchasers and the Holders of Transfer Restricted Securities being
     registered pursuant to any Shelf Registration Statement, as applicable, for
     the reasonable fees and disbursements of not more than one counsel, which
     shall be Simpson Thacher & Bartlett, or such other counsel as may be chosen
     by the Holders for whose benefit the Shelf Registration Statement is being
     prepared.

6.  INDEMNIFICATION AND CONTRIBUTION.

          (a) Each of the Issuer and the Guarantors shall indemnify and hold
harmless each Holder, such Holder's officers, directors and employees and each
person, if any, who controls such Holder within the meaning of the Securities
Act (each, an "INDEMNIFIED HOLDER"), from and against any loss, claim, damage or
liability, joint or several, or any action in respect thereof (including, but
not limited to, any loss, claim, damage, liability or action relating to resales
of the Transfer Restricted Securities), to which such Indemnified Holder may
become subject, insofar as any such loss, claim, damage, liability or action
arises out of, or is based upon:

               (i) any untrue statement or alleged untrue statement of a
          material fact contained in (A) any Shelf Registration Statement,
          Prospectus or amendment or supplement thereto or (B) any blue sky
          application or other document or any amendment or supplement thereto
          prepared or executed by the Issuer (or based upon written information
          furnished by or on behalf of the Issuer expressly for use in such blue
          sky application or other document or amendment on supplement) filed in
          any jurisdiction specifically for the purpose of qualifying any or all
          of the Transfer Restricted Securities under the securities law of any
          state or other jurisdiction (such application or document being
          hereinafter called a "BLUE SKY APPLICATION"); or

               (ii) the omission or alleged omission to state therein 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 shall reimburse each Indemnified Holder promptly upon demand for any
     legal or other expenses reasonably incurred by such Indemnified Holder in
     connection with investigating or

                                       15
<PAGE>

     defending or preparing to defend against any such loss, claim, damage,
     liability or action as such expenses are incurred; provided, however, that
     neither the Issuer nor any Guarantor shall be liable in any such case to
     the extent that any such loss, claim, damage, liability or action arises
     out of, or is based upon, any untrue statement or alleged untrue statement
     or omission or alleged omission made in any Shelf Registration Statement,
     Prospectus or amendment or supplement thereto or any Blue Sky Application
     in reliance upon and in conformity with written information furnished to
     the Issuer by or on behalf of such Holder (or its related Indemnified
     Holder) specifically for use therein. The foregoing indemnity agreement is
     in addition to any liability which the Issuer and the Guarantors may
     otherwise have to any Indemnified Holder.

          (b) Each Holder, severally and not jointly, shall indemnify and hold
     harmless the Issuer and the Guarantors, their respective officers,
     directors and employees and each person, if any, who controls the Issuer or
     the Guarantors within the meaning of the Securities Act, from and against
     any loss, claim, damage or liability, joint or several, or any action in
     respect thereof, to which the Issuer, the Guarantors or any such officer,
     director, employee or controlling person may become subject, insofar as any
     such loss, claim, damage or liability or action arises out of, or is based
     upon:

               (i) any untrue statement or alleged untrue statement of any
          material fact contained in any Shelf Registration Statement,
          Prospectus or amendment or supplement thereto or any Blue Sky
          Application; or

               (ii) the omission or the alleged omission to state therein any
          material fact required to be stated therein or necessary to make the
          statements therein, in light of the circumstances under which they
          were made, not misleading,

     but in each case 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 Issuer by or on
     behalf of such Holder (or its related Indemnified Holder) specifically for
     use therein, and shall reimburse the Issuer, the Guarantors and any such
     officer, director, employee or controlling person promptly upon demand for
     any legal or other expenses reasonably incurred by the Issuer, the
     Guarantors or any such officer, employee or controlling person in
     connection with investigating or defending or preparing to defend against
     any such loss, claim, damage, liability or action as such expenses are
     incurred. The foregoing indemnity agreement is in addition to any liability
     which any Holder may otherwise have to the Issuer, the Guarantors or any of
     their respective officers, directors, employees or controlling persons.

          (c) Promptly after receipt by an indemnified party under this Section
     6 of notice of any claim or the commencement of any action, the indemnified
     party shall, if a claim in respect thereof is to be made against the
     indemnifying party under this Section 6, notify the indemnifying party in
     writing of the claim or the commencement of that action; provided, however,
     that the failure to notify the indemnifying party shall not relieve it from
     any liability which it may have under this Section 6 except to the extent
     it has been materially prejudiced by such failure and, provided, further,
     that the failure to notify the indemnifying party shall not relieve it from
     any liability which it may have to an indemnified party otherwise than
     under this Section 6. If any such claim or action shall be brought against
     an indemnified party, and it shall

                                       16
<PAGE>

     notify the indemnifying party thereof, the indemnifying party shall be
     entitled to participate therein and, to the extent that it wishes, jointly
     with any other similarly notified indemnifying party, to assume the defense
     thereof with counsel satisfactory to the indemnified party. After notice
     from the indemnifying party to the indemnified party of its election to
     assume the defense of such claim or action, the indemnifying party shall
     not be liable to the indemnified party under this Section 6 for any legal
     or other expenses subsequently incurred by the indemnified party in
     connection with the defense thereof other than reasonable costs of
     investigation; provided, however, that Holders shall have the right to
     employ a single counsel to represent jointly the Holders and their
     respective officers, directors, employees and controlling persons who may
     be subject to liability arising out of any claim in respect of which
     indemnity may be sought by the Holders against the Issuer, the Guarantors
     or any of their respective officers, directors, employees or controlling
     persons under this Section 6, if the Holders seeking indemnification shall
     have been advised by legal counsel that there may be one or more legal
     defenses available to them and their respective officers, directors,
     employees and controlling persons that are different from or additional to
     those available to the Issuer, the Guarantors and their respective
     officers, directors, employees and controlling persons, and the fees and
     expenses of a single separate counsel shall be paid by the Issuer and the
     Guarantors. No indemnifying party shall:

               (i) without the prior written consent of the indemnified parties
          (which consent shall not be unreasonably withheld) settle or
          compromise or consent to the entry of any judgment with respect to any
          pending or threatened claim, action, suit or proceeding in respect of
          which indemnification or contribution may be sought hereunder (whether
          or not the indemnified parties are actual or potential parties to such
          claim or action) unless such settlement, compromise or consent
          includes an unconditional release of each indemnified party from all
          liability arising out of such claim, action, suit or proceeding, or

               (ii) be liable for any settlement of any such action effected
          without its written consent (which consent shall not be unreasonably
          withheld), but if settled with its written consent or if there be a
          final judgment for the plaintiff in any such action, the indemnifying
          party agrees to indemnify and hold harmless any indemnified party from
          and against any loss or liability by reason of such settlement or
          judgment.

          (d) If the indemnification provided for in this Section 6 shall for
     any reason be unavailable or insufficient to hold harmless an indemnified
     party under Section 6(a) or 6(b) in respect of any loss, claim, damage or
     liability (or action in respect thereof) referred to therein, each
     indemnifying party shall, in lieu of indemnifying such indemnified party,
     contribute to the amount paid or payable by such indemnified party as a
     result of such loss, claim, damage or liability (or action in respect
     thereof):

               (i) in such proportion as is appropriate to reflect the relative
          benefits received by the Issuer from the offering and sale of the
          Transfer Restricted Securities on the one hand and a Holder with
          respect to the sale by such Holder of the Transfer Restricted
          Securities on the other, or

               (ii) if the allocation provided by clause (6)(d)(i) is not
          permitted by applicable law, in such proportion as is appropriate to
          reflect not only the relative benefits referred

                                       17
<PAGE>

          to in clause 6(d)(i) but also the relative fault of the Issuer on the
          one hand and the Holders on the other in connection with the
          statements or omissions or alleged statements or alleged omissions
          that resulted in such loss, claim, damage or liability (or action in
          respect thereof), as well as any other relevant equitable
          considerations.

The relative benefits received by the Issuer on the one hand and a Holder on the
other with respect to such offering and such sale shall be deemed to be in the
same proportion as the total net proceeds from the offering of the Securities
purchased under the Purchase Agreement (before deducting expenses) received by
the Issuer, on the one hand, bear to the total proceeds received by such Holder
with respect to its sale of Transfer Restricted Securities on the other.  The
relative fault of the parties shall be determined by reference to 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 Issuer
and the Guarantors on the one hand or the Holders on the other, the intent of
the parties and their relative knowledge, access to information and opportunity
to correct or prevent such statement or omission.  The Issuer, the Guarantors
and each Holder agree that it would not be just and equitable if the amount of
contribution pursuant to this Section 6(d) were determined by pro rata
allocation or by any other method of allocation that does not take into account
the equitable considerations referred to in the first sentence of this paragraph
(d).  The amount paid or payable by an indemnified party as a result of the
loss, claim, damage or liability, or action in respect thereof, referred to
above in this Section 6 shall be deemed to include, for purposes of this Section
6, any legal or other expenses reasonably incurred by such indemnified party in
connection with investigating or defending or preparing to defend any such
action or claim.  Notwithstanding the provisions of this Section 6, no Holder
shall be required to contribute any amount in excess of the amount by which the
total price at which the Transfer Restricted Securities purchased by it were
resold exceeds the amount of any damages which such Holder has otherwise been
required to pay by reason of any 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' obligations to contribute as provided in this
Section 6(d) are several and not joint.

     7. RULE 144A. In the event the Issuer is not subject to Section 13 or 15(d)
of the Exchange Act, the Issuer and each of the Guarantors hereby agree with
each Holder, for so long as any Transfer Restricted Securities remain
outstanding, to make available to any Holder or beneficial owner of Transfer
Restricted Securities in connection with any sale thereof and any prospective
purchaser of such Transfer Restricted Securities from such Holder or beneficial
owner, the information required by Rule 144A(d)(4) under the Securities Act in
order to permit resales of such Transfer Restricted Securities pursuant to Rule
144A.

     8. PARTICIPATION IN UNDERWRITTEN REGISTRATIONS. No Holder may participate
in any Underwritten Registration hereunder unless such Holder:

               (i) agrees to sell such Holder's Transfer Restricted Securities
          on the basis provided in any underwriting arrangements approved by the
          Persons entitled hereunder to approve such arrangements; and

                                       18
<PAGE>

              (ii) completes and executes all reasonable questionnaires, powers
          of attorney, indemnities, underwriting agreements, lock-up letters and
          other documents required under the terms of such underwriting
          arrangements.

     9. SELECTION OF UNDERWRITERS. The Holders of Transfer Restricted Securities
covered by the Shelf Registration Statements who desire to do so may sell such
Transfer Restricted Securities in an Underwritten Offering if approved by the
Issuer. In any such Underwritten Offering, the investment banker or investment
bankers and manager or managers that will administer the offering will be
selected by a Majority of Holders whose Transfer Restricted Securities are
included in such offering; provided, that such investment bankers and managers
must be reasonably satisfactory to the Issuer.

     10.  MISCELLANEOUS.

          (a) REMEDIES. The Issuer and the Guarantors acknowledge and agree that
     any failure by the Issuer or the Guarantors to comply with their
     obligations under Section 2 hereof may result in material irreparable
     injury to the Initial Purchasers or the Holders for which there is no
     adequate remedy at law, that it will not be possible to measure damages for
     such injuries precisely and that, in the event of any such failure, the
     Initial Purchasers or any Holder may obtain such relief as may be required
     to specifically enforce the Issuer's and the Guarantors' obligations under
     Section 2 hereof. The Issuer and the Guarantors further agree to waive the
     defense in any action for specific performance that a remedy at law would
     be adequate.

          (b) ADJUSTMENTS AFFECTING TRANSFER RESTRICTED SECURITIES. The Issuer
     and the Guarantors shall not, directly or indirectly, take any action with
     respect to the Transfer Restricted Securities as a class that would
     adversely affect the ability of the Holders of Transfer Restricted
     Securities to include such Transfer Restricted Securities in a registration
     undertaken pursuant to this Agreement.

          (c) NO INCONSISTENT AGREEMENTS. The Issuer and the Guarantors will
     not, on or after the date of this Agreement, enter into any agreement with
     respect to its securities that is inconsistent with the rights granted to
     the Holders in this Agreement or otherwise conflicts with the provisions
     hereof. In addition, the Issuer shall not grant to any of its security
     holders (other than the Holders of Transfer Restricted Securities in such
     capacity) the right to include any of its securities in the Shelf
     Registration Statement provided for in this Agreement other than the
     Transfer Restricted Securities. The Issuer has not previously entered into
     any agreement (which has not expired or been terminated) granting any
     registration rights with respect to its securities to any Person which
     rights conflict with the provisions hereof.

          (d) AMENDMENTS AND WAIVERS. This Agreement may not be amended,
     modified or supplemented, and waivers or consents to or departures from the
     provisions hereof may not be given, unless the Issuer has obtained the
     written consent of a Majority of Holders or such greater percentage of the
     Holders as required by the Indenture.

          (e) NOTICES. All notices and other communications provided for or
     permitted hereunder shall be made in writing by hand-delivery, first-class
     mail (registered or certified,

                                       19

          (f) SUCCESSORS AND ASSIGNS. This Agreement shall inure to the benefit
     of and be binding upon the successors and assigns of each of the parties
     and any Person that becomes a Guarantor on any Roll-Up Date, including
     without limitation and without the need for an express assignment,
     subsequent Holders of Transfer Restricted Securities; provided, however,
     that (i) this Agreement shall not inure to the benefit of or be binding
     upon a successor or assign of a Holder unless and to the extent such
     successor or assign acquired Transfer Restricted Securities from such
     Holder and (ii) nothing contained herein shall be deemed to permit any
     assignment, transfer or other disposition of Transfer Restricted Securities
     in violation of the terms of the Purchase Agreement or the Indenture. If
     any transferee of any Holder shall acquire Transfer Restricted Securities,
     in any manner, whether by operation of law or otherwise, such Transfer
     Restricted Securities shall be held subject to all of the terms of this
     Agreement, and by taking and holding such Transfer Restricted Securities
     such person shall be conclusively deemed to have agreed to be bound by and
     to perform all of the terms and provisions of this Agreement.

          (g) 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

                                       20
<PAGE>

     shall be deemed to be an original and all of which taken together shall
     constitute one and the same agreement.

          (h) SECURITIES HELD BY THE ISSUER OR ITS AFFILIATES. Whenever the
     consent or approval of Holders of a specified percentage of Transfer
     Restricted Securities is required hereunder, Transfer Restricted Securities
     held by the Issuer or its "affiliates" (as such term is defined in Rule 405
     under the Securities Act) shall not be counted in determining whether such
     consent or approval was given by the Holders of such required percentage.

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

          (j) GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED
     IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

          (k) SEVERABILITY. If any one or more of the provisions contained
     herein, or the application thereof in any circumstance, is held invalid,
     illegal or unenforceable, the validity, legality and enforceability of any
     such provision in every other respect and of the remaining provisions
     contained herein shall not be affected or impaired thereby.

          (l) ENTIRE AGREEMENT. This Agreement is intended by the parties as a
     final expression of their agreement and 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. 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 Issuer and the Guarantors with respect to the Transfer Restricted
     Securities. This Agreement supersedes all prior agreements and
     understandings between the parties with respect to such subject matter.

with the CODES, the "TRANSFER RESTRICTED SECURITIES") of the Issuer understands
that the Issuer and the subsidiary guarantors (the "GUARANTORS") have filed, or
intend to file, with the Securities and Exchange Commission (the "COMMISSION")
one or more registration statements (collectively, the "SHELF REGISTRATION
STATEMENT"), for the registration and resale under Rule 415 of the Securities
Act of 1933, as amended (the "SECURITIES ACT"), of the Transfer Restricted

dispose of any Transfer Restricted Securities pursuant to the Shelf Registration

be required to be named as a selling securityholder in the related Prospectus,
deliver a Prospectus to purchasers of Transfer Restricted Securities and be
bound by those provisions of the Registration Rights Agreement applicable to
such beneficial owner (including certain indemnification provisions, as

     Certain legal consequences arise from being named as a selling
securityholder in the Shelf Registration Statement and the related Prospectus.
Accordingly, holders and beneficial owners of Transfer Restricted Securities are
advised to consult their own securities law counsel regarding the consequences
of being named or not being named as a selling securityholder in the Shelf
