FORM OF LETTER OF TRANSMITTAL

DELIVERY OF THIS INSTRUMENT TO AN ADDRESS OTHER THAN AS SET FORTH ABOVE, OR TRANSMISSION OF THIS LETTER OF TRANSMITTAL AND CONSENT VIA FACSIMILE OTHER THAN AS SET FORTH ABOVE, WILL NOT CONSTITUTE A VALID DELIVERY OF THIS LETTER OF TRANSMITTAL.

If you wish to (1) tender for exchange your Floating Rate Senior Contingent Convertible Debt Securities due 2033 (the “Old CODES”) of Apogent Technologies Inc., a Wisconsin corporation (the “Company”), for an equal aggregate principal amount of Floating Rate Convertible Senior Debentures due 2033 (the “New Debentures”), pursuant to the Company’s exchange offer (the “Exchange Offer”), and (2) consent to the proposed amendment (the “Proposed Amendment”) to the Resale Registration Rights Agreement, dated as of December 17, 2003, by and among the Company, the subsidiary guarantors named on the signature pages thereto and the initial purchasers of the Old CODES named on the signature pages thereto as described in the

Holders of the Old Floating Rate CODES who have previously validly delivered a letter of transmittal in conjunction with a valid tender of the Old Floating Rate CODES for exchange pursuant to the procedures described in the Prospectus under the heading “The Exchange Offer” are not required to take any further action to receive the New Floating Rate Debentures. Holders of the Old Floating Rate CODES who have previously validly tendered the Old Floating Rate CODES for exchange or who validly tender the Old Floating Rate CODES for exchange in accordance with this Letter may withdraw any Old Floating Rate CODES so tendered at any time prior to the consummation of the Exchange Offer. See the Prospectus under the heading “The Exchange Offer” for a more complete description of the tender and withdrawal provisions.

If you wish to be eligible to receive the Exchange Fee and Consent Fee, each as described in the accompanying prospectus, you must tender your Old CODES and deliver this Amended Letter of Transmittal and Consent to the Exchange Agent prior to the Expiration Time.

Please contact Innisfree M&A Incorporated, the information agent for this exchange offer and consent solicitation (the “Information Agent”), if you have any questions relating to the procedures for tendering outstanding Old CODES and delivering consents to the Proposed Amendment. You may also contact the information agent to obtain additional copies of this Letter of Transmittal and Consent or the accompanying prospectus. You may contact the Information Agent at the address and telephone numbers shown on the back cover of this Letter of Transmittal and Consent.

The undersigned acknowledges that he or she has received the preliminary prospectus, dated July 13, 2004 (together with any subsequent preliminary or final prospectus, the “Prospectus”), of Apogent Technologies Inc., a Wisconsin corporation (the “Company”), and this Amended Letter of Transmittal and Consent (the “Letter”), which together constitute (1) the Company’s offer to exchange an aggregate principal amount of up to $345,000,000 of the Company’s Floating Rate Convertible Senior Debentures due 2033 (individually a “New Debenture” and collectively, the “New Debentures”), for a like principal amount of the Company’s issued and outstanding Floating Rate Senior Contingent Convertible Debt Securities due 2033 (individually “Old CODES” and collectively, the “Old CODES”) from the registered holders thereof and (2) the Company’s solicitation of consents (the “Consent Solicitation”) to the proposed amendment (the “Proposed Amendment”) to the Resale Registration Rights Agreement, dated as of December 17, 2003 (the “Registration Rights Agreement”), by and among the Company, the subsidiary guarantors of the Old CODES named on the signature pages thereto and the initial purchasers of the Old CODES named on the signature pages thereto. The Proposed Amendment seeks to terminate the Registration Rights Agreement, and thereby, the Company’s obligation to register the Old CODES and the common stock issuable upon conversion of the Old CODES under the Securities Act of 1933, as amended (the “Securities Act”), for resale. If the requisite consents to the Proposed Amendment are received at or prior to the Expiration Time, the Company intends to execute the Proposed Amendment to the Registration Rights Agreement promptly following the Expiration Time and prior to accepting any Old CODES tendered in the Exchange Offer and Consent Solicitation for exchange.

Subject to the consummation of the Exchange Offer, if you validly tender your Old CODES and consent to the Proposed Amendment thereby, and do not withdraw your tender and consent prior to the consummation of the Exchange Offer, you will receive an exchange fee equal to 0.50% of the principal amount of the Old CODES tendered (the “Exchange Fee”) and a consent fee equal to 0.60% of the principal amount of the Old CODES tendered (the “Consent Fee”). If your Old CODES are not received prior to the Expiration Time, you will not receive the Exchange Fee or Consent Fee.

IF YOU TENDER YOUR OLD CODES IN THE EXCHANGE OFFER YOU WILL BE DEEMED TO CONSENT TO THE PROPOSED AMENDMENT IN THE CONSENT SOLICITATION THEREBY.

For each Old CODES accepted for exchange, the holder of such Old CODES will receive a New Debenture having a principal amount equal to the principal amount of the surrendered Old CODES. The New Debentures will bear interest from the date of issuance. Accordingly, registered holders of New Debentures, on the relevant record date for the first interest payment date following the consummation of the Exchange Offer and Consent Solicitation, will receive interest accruing from the date of issuance of the New Debentures.

This Letter is to be completed by a holder of Old CODES either if certificates for such Old CODES are to be forwarded herewith or if a tender is to be made by book-entry transfer to the account maintained by the Exchange Agent at The Depository Trust Company (“DTC”) pursuant to the procedures set forth in “The Exchange Offer — Book-Entry Transfers” section of the Prospectus and an Agent’s Message is not delivered. HOLDERS OF OLD CODES WHO VALIDLY TENDER OLD CODES FOR EXCHANGE AND THEIR CONSENT TO THE PROPOSED AMENDMENT THEREBY IN ACCORDANCE WITH THIS LETTER MAY WITHDRAW ANY OLD CODES SO TENDERED AND THEIR CONSENT THEREBY AT ANY TIME PRIOR TO THE CONSUMMATION OF THE EXCHANGE OFFER. SEE THE PROSPECTUS UNDER THE HEADINGS “THE EXCHANGE OFFER” AND “THE CONSENT SOLICITATION” FOR A MORE COMPLETE DESCRIPTION OF THE TENDER AND CONSENT AND WITHDRAWAL OF TENDER AND CONSENT PROVISIONS. Tenders and Consents by book-entry transfer also may be made by delivering an Agent’s Message in lieu of this Letter. The term “Agent’s Message” means a message, transmitted by DTC to and received by the Exchange Agent and forming a part of the confirmation of book-entry tender of Old CODES into the Exchange Agent’s account at DTC (a “Book-Entry Confirmation”), which states that DTC has received an express acknowledgment from the tendering and consenting participant, which acknowledgment states that such participant has received and agrees to be bound by this Letter and that the Company may enforce this Letter against such participant. See Instruction 1. Delivery of documents to DTC does not constitute delivery to the Exchange Agent.

THE METHOD OF DELIVERY OF OLD CODES, LETTERS OF TRANSMITTAL AND CONSENT AND ALL OTHER REQUIRED DOCUMENTS ARE AT THE ELECTION AND RISK OF THE HOLDERS. IF SUCH DELIVERY IS BY MAIL, IT IS RECOMMENDED THAT REGISTERED MAIL, PROPERLY INSURED, WITH RETURN RECEIPT REQUESTED, BE USED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY DELIVERY. NO LETTERS OF TRANSMITTAL OR OLD CODES SHOULD BE SENT TO THE COMPANY.

1. Delivery of this Letter and Old CODES. This Amended Letter of Transmittal and Consent (this “Letter”) is to be completed by holders of Old CODES either if certificates are to be forwarded herewith or if tenders and consents are to be made pursuant to the procedures for delivery by book-entry transfer set forth in “The Exchange Offer — Book-Entry Transfers” section of the Prospectus and an Agent’s Message is not delivered. Tenders and Consents by book-entry transfer also may be made by delivering an Agent’s Message in lieu of this Letter. The term “Agent’s Message” means a message, transmitted by DTC to and received by the Exchange Agent and forming a part of a Book-Entry Confirmation, which states that DTC has received an express acknowledgment from the tendering participant, which acknowledgment states that such participant has received and agrees to be bound by, and makes the representations and warranties contained in, the Letter and that the Company may enforce the Letter against such participant. Certificates for all physically tendered Old CODES, or Book-Entry Confirmation, as the case may be, as well as a properly completed and duly executed Letter (or manually signed facsimile hereof or Agent’s Message in lieu thereof) and any other documents required by this Letter, must be received by the Exchange Agent at the address set forth herein prior to the Expiration Time. Old CODES tendered hereby must be in denominations of a principal amount of $1,000 and any integral multiple thereof.

The method of delivery of this Letter, the Old CODES and all other required documents is at the election and risk of the tendering holders, but the delivery will be deemed made only when actually received or confirmed by the Exchange Agent. If Old CODES are sent by mail, it is suggested that the mailing be registered mail, properly insured, with return receipt requested, made sufficiently in advance of the Expiration Time to permit delivery to the Exchange Agent prior to 5:00 p.m., New York City time, on August 2, 2004, which is the Expiration Time, unless the Exchange Offer and Consent Solicitation is extended by the Company. See “The Exchange Offer” section of the Prospectus.

2. Withdrawal Rights. Tenders of Old CODES may be withdrawn at any time prior to the consummation of the Exchange Offer.

For a withdrawal of a tender of Old CODES to be effective, a written notice of withdrawal must be received by the Exchange Agent at the address set forth above prior to the consummation of the Exchange Offer, unless the Exchange Offer and Consent Solicitation is extended by the Company. See “The Exchange Offer” section of the Prospectus. Any such notice of withdrawal must (i) specify the name of the person having tendered the Old CODES to be withdrawn (the “Depositor”), (ii) identify the Old CODES to be withdrawn (including certificate number or numbers and the principal amount of such Old CODES), (iii) contain a statement that such holder is withdrawing such holder’s election to have such Old CODES exchanged, (iv) be signed by the holder in the same manner as the original signature on the Letter by which such Old CODES were tendered (including any required signature guarantees) or be accompanied by documents of transfer to have the trustee with respect to the Old CODES register the transfer of such Old CODES in the name of the person withdrawing the tender and (v) specify the name in which such Old CODES are registered, if different from that of the Depositor. If Old CODES have been tendered pursuant to the procedure for book-entry transfer set forth in “The Exchange Offer — Book-Entry Transfers” section of the Prospectus, any notice of withdrawal must specify the name and number of the account at DTC to be credited with the withdrawn Old CODES and otherwise comply with the procedures of such facility. All questions as to the validity, form and eligibility (including time of receipt) of such notices will be determined by the Company (which power may be delegated to the Exchange Agent), whose determination shall be final and binding on all parties. Any Old CODES so withdrawn will be deemed not to have been validly tendered for exchange for purposes of the Exchange Offer and Consent Solicitation and no New Debentures will be issued with respect thereto unless the Old CODES so withdrawn are validly retendered. Any Old CODES that have been tendered for exchange but which are not exchanged for any reason will be returned to the holder thereof without cost to such holder (or, in the case of Old CODES

tendered by book-entry transfer into the Exchange Agent’s account at DTC pursuant to the book-entry transfer procedures set forth in “The Exchange Offer — Book-Entry Transfers” section of the Prospectus, such Old CODES will be credited to an account maintained with DTC for the Old CODES) as soon as practicable after withdrawal, rejection of tender or termination of the Exchange Offer and Consent Solicitation. A holder who validly withdraws previously tendered Old CODES will not receive the Exchange Fee or Consent Fee with respect to those Old CODES unless those Old CODES are retendered prior to the Expiration Time using this Letter.

Properly withdrawn Old CODES may be retendered by following the procedures described above at any time prior to 5:00 p.m., New York City time, on the Expiration Time.

3. Consent to Proposed Amendments; Withdrawal of Tenders and Consents. In accordance with the Prospectus, all properly completed and executed copies of this Letter and all Agent’s Messages tendering Old CODES by holders who are not “affiliates” (as such term is defined in Rule 405 under the Securities Act) of the Company that are received by the Exchange Agent will be counted as consents with respect to the Proposed Amendment, unless the Exchange Agent receives, on or prior to the Expiration Time, a written notice of withdrawal as described above.

The valid withdrawal of a Holder’s Old CODES tendered previously pursuant to this Letter will constitute the concurrent valid withdrawal of such holder’s consent to the Proposed Amendment. As a result, a holder who validly withdraws previously tendered Old CODES prior to the consummation of the Exchange Offer will not receive the Exchange Fee or Consent Fee with respect to those Old CODES unless those Old CODES are retendered prior to the Expiration Time using this Letter. Any withdrawal of previously tendered Old CODES otherwise than in accordance with the provisions described above will not constitute a valid withdrawal of such holder’s consent to the Proposed Amendment. Old CODES tendered and consents validly delivered using this Letter on or prior to the Expiration Time may not be withdrawn after the consummation of the Exchange Offer.

IF THE REQUISITE CONSENTS TO THE PROPOSED AMENDMENT ARE RECEIVED PRIOR TO THE EXPIRATION TIME, THE COMPANY INTENDS TO EXECUTE THE PROPOSED AMENDMENT PROMPTLY FOLLOWING THE EXPIRATION TIME. IF THE PROPOSED AMENDMENT IS EXECUTED AND BECOMES OPERATIVE, THE AMENDMENT TO THE REGISTRATION RIGHTS AGREEMENT WILL BE BINDING UPON EACH HOLDER OF OUTSTANDING OLD CODES WHETHER OR NOT SUCH HOLDER GIVES A CONSENT WITH RESPECT THERETO.

4. Partial Tenders And Consents (not applicable to holders who tender by book-entry transfer). If less than all of the Old CODES evidenced by a submitted certificate are to be tendered, the tendering holder(s) should fill in the aggregate principal amount of Old CODES to be tendered in the box above entitled “Description of Old CODES — Principal Amount Tendered and as to which Consents are Given.” A reissued certificate representing the balance of nontendered Old CODES will be sent to such tendering holder, unless otherwise provided in the appropriate box on this Letter, promptly after the Expiration Time. ALL OF THE OLD CODES DELIVERED TO THE EXCHANGE AGENT WILL BE DEEMED TO HAVE BEEN TENDERED (AND THE HOLDER OF SUCH OLD CODES WILL BE THEREBY DEEMED TO CONSENT TO THE PROPOSED AMENDMENT WITH RESPECT TO SUCH OLD CODES) UNLESS OTHERWISE INDICATED.

5. Signatures on this Letter; Bond Powers and Endorsements; Guarantee of Signatures. If this Letter is signed by the Holder of the Old CODES tendered hereby, the signature must correspond exactly with the name as written on the face of the certificates or on DTC’s security position listing as the holder of such Old CODES without any change whatsoever.

If any tendered Old CODES are owned of record by two or more joint owners, all of such owners must sign this Letter.

If any tendered Old CODES are registered in different names on several certificates, it will be necessary to complete, sign and submit as many separate copies of this Letter as there are different registrations of certificates.

When this Letter is signed by the registered holder or holders of the Old CODES specified herein and tendered hereby, no endorsements of certificates or separate bond powers are required. If, however, the New Debentures are to be issued, or any untendered Old CODES are to be reissued, to a person other than the registered holder, then endorsements of any certificates transmitted hereby or separate bond powers are required. Signatures on such certificate(s) must be guaranteed by a participant in a securities transfer association recognized signature program.

If this Letter is signed by a person other than the registered holder or holders of any certificate(s) specified herein, such certificate(s) must be endorsed or accompanied by appropriate bond powers, in either case signed exactly as the name or names of the registered holder or holders appear(s) on the certificate(s) and signatures on such certificate(s) must be guaranteed by an Eligible Institution.

If this Letter or any certificates or bond powers are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, such persons should so indicate when signing, and, unless waived by the Company, proper evidence satisfactory to the Company of their authority to so act must be submitted.

ENDORSEMENTS ON CERTIFICATES FOR OLD CODES OR SIGNATURES ON BOND POWERS REQUIRED BY THIS INSTRUCTION 5 MUST BE GUARANTEED BY A FIRM WHICH IS A FINANCIAL INSTITUTION (INCLUDING MOST BANKS, SAVINGS AND LOAN ASSOCIATIONS AND BROKERAGE HOUSES) THAT IS A PARTICIPANT IN THE SECURITIES TRANSFER AGENTS MEDALLION PROGRAM, THE NEW YORK STOCK EXCHANGE MEDALLION SIGNATURE PROGRAM OR THE STOCK EXCHANGES MEDALLION PROGRAM (EACH AN “ELIGIBLE INSTITUTION”).

SIGNATURES ON THIS LETTER NEED NOT BE GUARANTEED BY AN ELIGIBLE INSTITUTION, PROVIDED THE OLD CODES ARE TENDERED: (I) BY A REGISTERED HOLDER OF OLD CODES (WHICH TERM, FOR PURPOSES OF THE EXCHANGE OFFER, INCLUDES ANY PARTICIPANT IN DTC’S SYSTEM WHOSE NAME APPEARS ON A SECURITY POSITION LISTING AS THE HOLDER OF SUCH OLD CODES) WHO HAS NOT COMPLETED THE BOX ENTITLED “SPECIAL ISSUANCE INSTRUCTIONS” OR “SPECIAL DELIVERY INSTRUCTIONS” ON THIS LETTER, OR (II) FOR THE ACCOUNT OF AN ELIGIBLE INSTITUTION.

6. Special Issuance and Delivery Instructions. Tendering holders of Old CODES should indicate in the applicable box the name and address to which New Debentures issued pursuant to the Exchange Offer and/or substitute certificates evidencing Old CODES not exchanged are to be issued or sent, if different from the name or address of the person signing this Letter. In the case of issuance in a different name, the employer identification or social security number of the person named also must be indicated. Holders tendering Old CODES by book-entry transfer may request that Old CODES not exchanged be credited to such account maintained at DTC as such holder may designate hereon. If no such instructions are given, such Old CODES not exchanged will be returned to the name and address of the person signing this Letter.

7. Taxpayer Identification Number and Backup Withholding. Federal income tax law generally requires that a tendering holder whose Old CODES are accepted for exchange and who is not exempt from backup withholding must provide the Exchange Agent (as payor) with such holder’s correct Taxpayer Identification Number (a “TIN”), which, in the case of a holder who is an individual, is generally such holder’s social security number. If the Exchange Agent is not provided with the correct TIN or an adequate basis for an exemption, such holder may be subject to a $50 penalty imposed by the Internal Revenue Service and backup withholding in an amount equal to 28% of the amount of any reportable payments made in connection with or after the exchange to such tendering holder. If withholding results in an overpayment of taxes, a refund may be obtained.

To prevent backup withholding, each tendering holder must generally provide such holder’s correct TIN by completing the “Substitute Form W-9” set forth herein, certifying that the TIN provided is correct (or that such holder is awaiting a TIN) and that (i) the holder is exempt from backup withholding, (ii) the holder has not been notified by the Internal Revenue Service that such holder is subject to backup withholding as a result of a

If the holder does not have a TIN, such holder should consult the enclosed Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9 (the “W-9 Guidelines”) for instructions on applying for a TIN, write “Applied For” in the space for the TIN in Part 1 of the Substitute Form W-9, and sign and date the Substitute Form W-9 and the Certificate of Awaiting Taxpayer Identification Number set forth herein. If the holder does not provide such holder’s TIN to the Exchange Agent within 60 days, backup withholding will begin and continue until such holder furnishes such holder’s TIN to the Exchange Agent. NOTE: WRITING “APPLIED FOR” ON THE FORM MEANS THAT THE HOLDER HAS ALREADY APPLIED FOR A TIN OR THAT SUCH HOLDER INTENDS TO APPLY FOR ONE IN THE NEAR FUTURE.

If the Old CODES are held in more than one name or are not in the name of the actual owner, consult the W-9 Guidelines for information on which TIN to report.

Exempt holders (including, among others, all corporations and certain foreign individuals) are not subject to these backup withholding and reporting requirements. To prevent possible erroneous backup withholding, an exempt holder should write “Exempt” in Part 2 of Substitute Form W-9. See the W-9 Guidelines for additional instructions. In order for a nonresident alien or foreign entity to qualify as exempt, such person must submit a completed Form W-8 BEN, “Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding,” signed under penalty of perjury attesting to such exempt status. Such form may be obtained from the Exchange Agent.

8. Transfer Taxes. The Company will pay all transfer taxes, if any, applicable to the transfer of Old CODES to it or its order pursuant to the Exchange Offer. If, however, New Debentures and/or substitute Old CODES not exchanged are to be delivered to, or are to be registered or issued in the name of, any person other than the registered holder of the Old CODES tendered hereby, or if tendered Old CODES are registered in the name of any person other than the person signing this Letter, or if a transfer tax is imposed for any reason other than the transfer of Old CODES to the Company or its order pursuant to the Exchange Offer, the amount of any such transfer taxes (whether imposed on the registered holder or any other persons) will be payable by the tendering holder. If satisfactory evidence of payment of such taxes or exemption therefrom is not submitted herewith, the amount of such transfer taxes will be billed directly to such tendering holder. EXCEPT AS PROVIDED IN THIS INSTRUCTION 8, IT WILL NOT BE NECESSARY FOR TRANSFER TAX STAMPS TO BE AFFIXED TO THE OLD CODES SPECIFIED IN THIS LETTER.

9. Waiver of Conditions. The Company reserves the right (subject to the limitations described in the Prospectus) to waive satisfaction of any or all conditions enumerated in the Prospectus.

10. No Conditional Tenders; Defects. No alternative, conditional, irregular or contingent tenders will be accepted. All tendering holders of Old CODES, by execution of this Letter or an Agent’s Message in lieu thereof, shall waive any right to receive notice of the acceptance of their Old CODES for exchange.

Neither the Company, the Exchange Agent nor any other person is obligated to give notice of any defect or irregularity with respect to any tender of Old CODES nor shall any of them incur any liability for failure to give any such notice.

11. Mutilated, Lost, Stolen or Destroyed Old CODES. Any holder whose Old CODES have been mutilated, lost, stolen or destroyed should contact the Exchange Agent at the address indicated above for further instructions.

12. Requests for Assistance or Additional Copies. Questions relating to the procedure for tendering and consenting thereby, as well as requests for additional copies of the Prospectus, this Letter and other related documents may be directed to the Exchange Agent, at the address and telephone number indicated above. A holder of Old CODES may also contact Innisfree M&A Incorporated, the information agent for the Exchange Offer and Consent Solicitation, or Goldman, Sachs & Co., the Dealer-Manager for the Exchange

You must cross out item (2) in Part 3 above if you have been notified by the IRS that you are currently subject to backup withholding because of underreporting interest or dividends on your tax return.

YOU MUST COMPLETE THE FOLLOWING CERTIFICATE IF YOU WROTE “APPLIED FOR” IN PART 1 OF THE SUBSTITUTE FORM W-9.

I certify under penalties of perjury that a taxpayer identification number has not been issued to me, and that I mailed or delivered an application to receive a taxpayer identification number to the appropriate Internal Revenue Service Center or Social Security Administration Office (or I intend to mail or deliver an application in the near future). I understand that if I do not provide a taxpayer identification number to the Payor within 60 days, the Payor is required to withhold 28 percent of all cash payments made to me thereafter until I provide a number.


NOTE:	FAILURE TO COMPLETE AND RETURN THIS FORM MAY RESULT IN A $50 PENALTY IMPOSED BY THE INTERNAL REVENUE SERVICE AND IN BACKUP WITHHOLDING OF TWENTY-EIGHT PERCENT OF ANY CASH PAYMENTS. PLEASE REVIEW THE ENCLOSED GUIDELINES FOR CERTIFICATION OF TAXPAYER IDENTIFICATION NUMBER ON SUBSTITUTE FORM W-9 FOR ADDITIONAL DETAILS.

Manually signed copies of the Letter will be accepted. The Letter and any other required documents should be sent or delivered by each holder or such holder’s broker, dealer commercial bank or other nominee to the Exchange Agent at one of the addresses set forth below.
