otherwise own or control, directly or indirectly, or have any ownership interest
in, any other corporation, association, joint venture, business entity or

pursuant to this Agreement shall be issued and outstanding on the date of
issuance to PE of the PE Shares. At the time of issuance of the PE Shares, there

securities laws.

4.       Representations, Warranties and Covenants of PE

PE hereby represents, warrants and covenants to Quantech and to Newco, with
respect to the purchase of the PE Shares, as follows:

4.1 Experience; Risk. PE has such knowledge and experience in financial and
business matters that it is capable of evaluating the merits and risks of the
purchase of the PE Shares pursuant to this Agreement and of protecting PE's

                                       3
<PAGE>

interests in connection therewith. PE is able to fend for itself in the
transactions contemplated by this Agreement and has the ability to bear the
economic risk of the investment, including complete loss of the investment. PE
is experienced in evaluating and investing in new companies such as the Newco.

4.2 Investment. PE is acquiring the PE Shares for investment for its own
account, not as a nominee or agent, and not with a view to, or for resale in
connection with, any distribution thereof, and PE has no present intention of
selling, granting any participation in, or otherwise distributing the same. PE
understands that the PE Shares to be purchased have not been registered under
the Securities Act by reason of a specific exemption from the registration
provisions of the Securities Act which depends upon, among other things, the
bona fide nature of the investment intent and the accuracy of such PE's
representations as expressed herein.

4.3 Restricted Securities; Rule 144. PE understands that the PE Shares will be
"restricted securities" under the federal securities laws inasmuch as they are
being acquired from the Newco in a transaction not involving a public offering
and that under such laws and applicable regulations the PE Shares may be resold
without registration under the Securities Act only in certain limited
circumstances. PE acknowledges that the PE Shares must be held indefinitely
unless subsequently registered under the Securities Act or an exemption from
such registration is available. PE is aware of the provisions of Rule 144
promulgated under the Securities Act which permit limited resale of shares
purchased in a private placement subject to the satisfaction of certain
conditions, including, among other things, the existence of a public market for
the shares, the availability of certain current public information about the
Newco, the resale occurring not less than one year (two years for affiliates)
after a party has purchased and paid for the security to be sold, the sale being
effected through a "broker's transaction" or in transactions directly with a
"market maker" (as provided by Rule 144(f)) and the number of shares being sold
during any three-month period not exceeding specified limitations.

4.4 Start Up Newco; No Public Market. PE understands that Newco will be a start
up company with limited assets, and that no public market now exists for any of
the securities issued by the Newco and that there is no assurance that a public
market will ever exist for the PE Shares.

4.5 Authorization. PE represents that it has the full right, power and authority
to enter into and perform PE's obligations under this Agreement, and this
Agreement when executed and delivered by PE will constitute legal, valid and
binding obligations of PE.

4.7 Further Limitations on Disposition. Without in any way limiting the
representations set forth above, PE further agrees not to make any disposition
of all or any portion of the PE Shares (other than transfers not involving a
change in beneficial ownership) unless and until:

                                       4
<PAGE>

         4.7.1 There is then in effect a registration statement under the
Securities Act covering such proposed disposition and such disposition is made
in accordance with such registration statement; or

         4.7.2 PE shall have notified the Newco of the proposed disposition and,
if reasonably requested by the Newco, such Purchaser shall have furnished the
Newco with an opinion of counsel, reasonably satisfactory to the Newco, that
such disposition will not require registration under the Securities Act.

4.8 Legends. It is understood that each certificate representing the PE Shares,
and any securities issued in respect thereof or exchange therefor shall bear
legends in the following forms (in addition to any legend required under
applicable state securities laws):

         "THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
         1933. THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED
         IN THE ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO
         THE SECURITIES UNDER SUCH ACT OR AN OPINION OF COUNSEL SATISFACTORY TO
         THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED."

         (i)      Permitted Sales of Refused Securities. In the event that a
                  Notice of Acceptance is not given by PE or Quantech, as the
                  case may be, in respect of all of the PE Offered Securities
                  and Joint Offered Securities (the "Offered Securities")
                  offered, Newco or Quantech, as the case may be, shall have

                  conditions, including, without limitation, unit price and

                  Quantech, as the case may be, than those set forth in the

                  PE or Quantech, as the case may be, shall propose to sell less
                  than all of the Refused Securities (any such sale to be in the
                  manner and on the terms specified in Section 5.2(i) above),
                  then the party receiving the offer shall reduce the number of
                  shares or other units of the Offered Securities specified in
                  its Notice of Acceptance to an amount which shall be not less
                  than the amount of the offered Securities electeded to be
                  purchased pursuant to Section 5.2 multiplied by a fraction,
                  (I) the numerator of which shall be the amount of Offered
                  Securities which Newco, PE or Quantech, as the case may be,
                  actually proposes to sell, and (II) the denominator of which
                  shall be the amount of all offered securities. In the event
                  that PE or Quantech, as the case may be, so elects to reduce
                  the number or amount of Offered Securities specified in its
                  Notice of Acceptance, neither Newco, PE or Quantech, as the
                  case may be, may sell or otherwise dispose of more than the
                  reduced amount of the Offered Securities until such securities
                  have again been offered in accordance with Section 5.1.

         (iii)    Closing. Upon the closing, which shall include full payment to
                  Newco, PE or Quantech, as the case may be, of the sale to such
                  other person or persons of all or less than all the Refused
                  Securities, PE or Quantech shall purchase from the offering

                                       6
<PAGE>

                  party, as the case may be, and the offering party shall sell
                  to PE or Quantech, as the case may be, the number of Offered
                  Securities specified in the Notice of Acceptance, as reduced
                  pursuant to Section 5.2(ii) upon the terms and conditions
                  specified in the Offer. The purchase by PE or Quantech of any
                  Offered Securities is subject in all cases to the preparation,
                  execution and delivery by Newco, PE and/or Quantech, as the
                  case may be, of a purchase agreement relating to such Offered
                  Securities reasonably satisfactory in form and substance to
                  the party making the offer.

5.3 Further Sale. In each case, any Offered Securities not purchased by PE,
Quantech or other person or persons in accordance with Section 5.1 may not be
sold or otherwise disposed of until they are again offered to PE or Quantech
under the procedures specified in Sections 5.1 - 5.3.

5.4 Termination of Right of First Refusal. The rights of PE under this Section 5

         (i)      Common Stock issued as a stock dividend to holders of Common
                  Stock or upon any subdivision or combination of shares of
                  Common Stock;

         (ii)     Preferred stock issued as a dividend to holders of preferred
                  stock upon any subdivision or combination of shares of

                  stock issuable upon conversion of the preferred stock as a
                  percentage of the total equity of Newco shall remain the same;

         (iii)    the issuance of common stock upon conversion of any preferred
                  stock or any other convertible securities of Newco issued in
                  accordance with this Section 5.

5.6 Except subject to and pursuant to Sections 5.1 through 5.3, inclusive, of
this Agreement, Newco shall not take or permit to be taken any action that would
cause PE's ownership of equity securities of Newco to diminish as a percentage
of Quantech's ownership of equity of Newco without PE's express written consent,
which may be withheld for any reason or for no reason; and Newco shall offer PE
the opportunity to participate in, and permit PE to participate in, any offering
of shares pursuant to a registration statement to the same proportionate extent
and on the same terms and conditions as Quantech is offered the opportunity to
or is permitted to participates in any such offering of shares.

5.7 All of PE's and Quantech's rights set forth in this Section 5 shall
terminate in the event that Newco sells shares to the public pursuant to a
registration statement filed under the Securities Act of 1933, as amended, with
the United States Securities and Exchange Commission, provided, however, that if
Quantech or PE are allowed to sell shares in such public offering each of PE and

                                       7
<PAGE>

respective ownership interests in Newco so that Quantech and PE will have a pro
rata right to sell shares based upon such ownership interest.

member, and copies of all such actions signed by members of the Board promptly
after it has been executed by all members of the Board. PE's representative
shall not have any voting power or duty to the Board or to Newco, but shall have
the right to participate in discussions at meetings of the Board. PE's rights
under this Section 6 will terminate at such time as PE's ownership interest in
each and every class of equity securities owned by PE drops below one percent
(1%) of the number of issued and outstanding shares or amounts of each such
class.

7.       EXECUTION BY NEWCO.

Promptly after the filing of Newco's Articles of Incorporation with the
Secretary of State of Minnesota, Quantech shall cause Newco to execute and

PE shall have no liability to Quantech and shall not be deemed to have
indemnified Quantech with respect to any product manufactured, used or sold by
Newco, or which Newco has manufactured.

9.       TRANSFER OF BREADBOARD INSTRUMENTS

breadboard instruments identified in Exhibit 9, and shall transfer all of PE's
right, title and interest in and to such breadboard instruments to Newco. Such

                  d)       Notwithstanding the foregoing provisions of this
                           Section 4.1, no royalties shall be payable to PE
                           under Sections 4.1(a), 4.1(b) or 4.1(c) for any of
                           the first three million US dollars ($3,000,000) in
                           sales by Newco or Newco Sublicensees of products with
                           respect to which royalties or Sublicense Royalties
                           are payable pursuant to this agreement, but royalties
                           and Sublicense Royalties shall be payable for all
                           sales in excess of such first three million US

                           dollars ($3,000,000). For the purposes of this
                           Section 4(d), each sale of any such product shall be
                           deemed to be for an amount equal to the higher of the
                           actual price received by Newco from its customer
                           (whether an end user customer or a distributor) or
                           Newco's US list retail sales price of the product
                           from time to time in effect. The value of sales by
                           Sublicensees shall be deemed to be the sales on which
                           royalties are paid to Newco.

                  e)       Also notwithstanding the foregoing provisions of this
                           Section 4.1, in the event that EG&G has not requested
                           on or before February 1, 2000, pursuant to Section
                           11.3 of this Agreement, to sublicense exclusively all
                           of the rights and technology licensed to Newco
                           pursuant to Sections 2.1 and 2.2 of this Agreement in
                           the fields of (i) food and beverages, (ii)
                           environmental and (iii) chemical and industrial
                           (collectively, the "EG&G Fields"), and such rights
                           are not sublicensed to EG&G, then Newco shall be
                           relieved of its obligations to pay royalties to PE
                           for License Products sold exclusively for use in one
                           or more EG&G Fields, and, instead of paying such
                           royalties to PE, Newco shall pay the royalties
                           otherwise due PE directly to Quantech.

         4.2      Status Reports. If Newco shall not have begun selling Licensed
                  Products by December 31, 2000, at the end of each Calendar
                  Quarter thereafter Newco shall deliver to PE and Quantech a
                  Statement of Intent signed by a duly authorized employee of
                  Newco (initially Gregory Freitag) stating that Newco is
                  continuing to pursue research and development efforts with an
                  intent to commercialize, or is continuing commercialization
                  of, Licensed Products. The obligation to provide such
                  quarterly Statements of Intent shall terminate upon the
                  earlier of the sale of the first Licensed Product or payment
                  of the first royalty payment under Section 4.1. If Newco shall
                  fail to timely deliver a Statement of Intent, PE may notify
                  Newco of this failure. If Newco fails to deliver the Statement
                  of Intent within one month of PE's notice, Newco's license
                  rights granted in Section 2 shall immediately terminate, and
                  all of Newco's right, title and interest in and to Newco
                  Intellectual Property, and instrumentation, breadboards and
                  other equipment relating to or incorporating Newco
                  Intellectual Property, and physical possession thereof, will
                  be transferred and turned over to PE in its then "as is"
                  condition. Notwithstanding anything to the contrary contained
                  herein, it will be deemed an immediate failure to provide a
                  status report in the event of the entry of a decree or order
                  for relief by a court having jurisdiction over Newco in an
                  involuntary case under the federal bankruptcy laws, or such
                  similar laws of any other country as now or hereafter
                  constituted, or any other applicable federal, state, or
                  foreign bankruptcy, insolvency or other similar law, or
                  appointing a receiver, liquidator, assignee, custodian,
                  trustee, sequestrator (or similar official) of Newco or for
                  any substantial part of its property, or ordering the
                  winding-up or liquidation of its affairs and the continuance
                  of any such decree or order unstayed and in effect for a
                  period of 60 consecutive days, or the commencement by Newco of

                                       8
<PAGE>

                  a voluntary case under the federal bankruptcy laws, or such
                  similar laws of any other country as now constituted or
                  hereafter amended, or any other applicable federal, state or
                  foreign bankruptcy, insolvency or other similar law, or the
                  consent by it to the appointment of or taking possession by a
                  receiver, liquidator, assignee, trustee, custodian,
                  sequestrator (or similar official) of Newco or for any
                  substantial part of its property, or the making by it of any
                  assignment for the benefit of creditors, or the failure of
                  Newco generally to pay its debts as such debts become due, or
                  the taking of action by Newco in furtherance of any of the
                  foregoing."

         4.3      Reports and Payments. Within thirty (30) days after the end of
                  each Calendar Quarter, Newco shall provide PE with a written
                  report itemizing the number of Licensed Consumables and the
                  number of Licensed Instruments sold, the Net Sales price of
                  each Licensed Product and a calculation of the Royalty for
                  such Calendar Quarter. PE shall respond in writing to confirm
                  agreement with reported sales and proposed payments which will
                  cause Newco to pay the entire Total Royalties to PE within 30
                  days.

         4.4      Records. Newco agrees to keep accurate written records
                  sufficient in detail to enable the royalties payable under
                  this Agreement by Newco to be determined and verified. Such
                  records for a particular calendar year shall be retained by
                  Newco for a period consistent with its then corporate record
                  retention policy.

         4.5      Audit of Records. Upon reasonable notice and during regular
                  business hours, Newco shall make available such records for
                  audit by an independent accountant selected by PE to verify
                  the accuracy of the reports provided to PE. Such audits shall
                  be at the expense of PE, provided, however, that if any such
                  audit reveals underpayment of royalties by the greater of
                  $50,000 or 10% then Newco shall pay the cost of such audit.

5.       TERM AND TERMINATION

         5.1.     Term. Unless license rights are otherwise terminated under
                  provisions of this Article 5, royalties owed pursuant to this
                  Agreement shall continue for twenty years from the execution
                  of this Agreement or until the expiration of all Patent
                  Rights, whichever is later, after which the Newco License
                  shall be deemed fully paid-up.

         5.2.     Termination. If either party breaches any of the material
                  terms, conditions or agreements of this Agreement, then the
                  other party may terminate this Agreement, at its option and
                  without prejudice to any of its other legal and equitable

                                       9
<PAGE>

                  rights and remedies, by giving the breaching party thirty (30)
                  days notice in writing, particularly specifying the breach.
                  Such notice of termination shall not be effective if the other
                  party cures the specified breach within such thirty (30) day
                  period, or, in the case of breaches not reasonably curable
                  within such thirty (30) days, if such party commences the cure
                  thereof within such thirty (30) days and diligently thereafter
                  prosecutes such cure.

         5.3.     Survival. Without limitation, termination of this Agreement
                  shall not relieve Newco from its obligation to make all
                  royalty payments and reports, including a terminal report,
                  provided for herein. PE shall have the right to make a final
                  audit within 60 days after receiving Newco's terminal report.

         5.4.     Sale of Inventory. Upon termination of the Licenses pursuant
                  to Section 5.2, Newco shall cease production of Licensed
                  Products. Newco shall be permitted to sell its inventory of
                  Licensed Products, and shall provide PE with a terminal
                  royalty report within 30 days after the last such sale of
                  Licensed Products.

         5.5.     Sublicenses. Termination of this Agreement shall cause
                  sublicenses granted hereunder to revert to PE.

         5.6.     End-User Licenses. Any license to end users will remain in
                  effect upon termination of this agreement and at no additional
                  payment by the end user.

         5.7      Transfer of Certain Property Upon Termination. Upon any
                  termination of this Agreement, except solely a termination by
                  reason of a breach by PE, all of Newco's right, title and
                  interest in and to Newco Intellectual Property, and
                  instrumentation, breadboards and other equipment relating to
                  or incorporating Newco Intellectual Property, and physical
                  possession thereof, will be transferred and turned over to PE
                  in its then "as is" condition.

6.       CONFIDENTIALITY

         6.1.     Intellectual Property. The parties acknowledge that the PE
                  Confidential Information and the Newco Confidential
                  Information are proprietary and confidential. The parties
                  respectively agree, therefore, to make all commercially
                  reasonable efforts to preserve the confidentiality of such
                  information. Notwithstanding the foregoing, a party may
                  disclose such information as follows:

                  a)       If disclosure is required by any applicable
                           government agency, regulation, or statute; however,
                           the other party shall be notified in time to permit
                           it to obtain a protective order with respect to such
                           Confidential Information; or

                  b)       If prior written consent is obtained from the other
                           party.

         6.2.     Disclosure of Agreement. Neither party may make any public
                  announcement regarding this Agreement or otherwise disclose
                  the terms of this Agreement without the prior approval of the
                  other party except as required by law.

9.       LITIGATION

         9.1.     Charges of Newco Infringement. If notice is received by either
                  party charging that any Licensed Product(s) made by, made for,
                  used by or sold by Newco infringes any patent, copyright,
                  trade secret, intellectual property, or other proprietary
                  right of such third party, the party receiving such notice
                  will promptly notify the other party to this Agreement. Newco
                  and PE agree to enter into discussions, and where necessary,
                  to work out, if possible, a mutually acceptable change in such
                  Licensed Product(s) to avoid such alleged infringement. If no
                  such mutually satisfactory change can be worked out, Newco and
                  PE agree to collaborate and enter into discussions with such
                  third party for the purpose of negotiating a settlement. If no
                  settlement can be agreed upon, Newco shall have the right but
                  not the obligation to defend any suit for infringement brought
                  against it by the third party. If Newco shall elect not to
                  defend such an infringement suit, Newco shall promptly notify
                  PE to that effect and PE shall thereafter have the right but
                  not the obligation to defend the suit.

         9.2.     Charges of Third Party Infringement. If either party knows or
                  has reason to believe that any rights in any Joint Invention

                                       12
<PAGE>

                  or any rights under the Patent Rights, Newco Intellectual
                  Property or PE Intellectual Property licensed hereunder is
                  being infringed directly, by inducement, or contributorily by
                  a third party, the party possessing such knowledge or belief
                  shall promptly notify the other party thereof. PE shall have
                  the first right to commence judicial proceedings for its own
                  benefit to attempt to stop such infringement but shall not be
                  obligated to do so. If, within one hundred eighty (180) days
                  after first obtaining such knowledge or belief concerning
                  infringement, PE has failed either to stop such infringement
                  or to initiate judicial proceedings, or if PE in writing so
                  authorizes Newco, Newco shall have the right to initiate for
                  its own benefit such judicial proceedings in its own name
                  provided, however, that Newco shall indemnify, defend and hold
                  PE harmless against any costs, fees, damages, liabilities or
                  other expenses relating thereto. The party initiating judicial
                  proceedings shall be entitled to retain any award resulting
                  therefrom.

         9.3.     Validity and Construction. If a judgment or decree is entered
                  in any proceeding in which the validity or infringement of any
                  claim of any Patent Rights is in issue, which judgment or
                  decree is not appealed or further appealable (such judgment or
                  decree being hereinafter referred to as an "Irrevocable
                  Judgment"), the validity of and/or construction placed upon
                  any such claim by the Irrevocable Judgment shall thereafter be
                  followed. If there are two or more conflicting Irrevocable
                  Judgments with respect to the same claim, the decision of the
                  higher court shall be followed. If an Irrevocable Judgment
                  holds one or more of the Patent Rights or any claims thereof
                  to be invalid or unenforceable, Newco hereby agrees, in
                  consideration of its freedom to make, use and sell Licensed
                  Products prior to such Irrevocable Judgment without fear of
                  suit by PE, and of PE's refraining from bringing suit against
                  Newco for infringement, and regardless of whatever action
                  Newco might take subsequent to such Irrevocable Judgment, that
                  it shall not be entitled to the retention or return of any
                  royalties, Deficiency Payment or Minimum Royalty Payment
                  payable or paid by Newco to PE hereunder prior to the date of
                  such Irrevocable Judgment.

10.      MISCELLANEOUS PROVISIONS

         10.1.    Trademarks. Nothing in this Agreement shall be deemed to grant
                  either party any right to use any trademark owned by the other
                  party in connection with the sales of the party's products.

         10.2.    Marking. Newco shall use all commercially reasonable efforts
                  to see to it that all Licensed products sold shall be
                  appropriately marked with the applicable patent number(s) of
                  the Patent Rights, in conformity with applicable law.

         10.3.    LIMITATION OF REMEDIES. PE SHALL HAVE NO LIABILITY TO ANY
                  PERSON FOR INDIRECT, INCIDENTAL, CONSEQUENTIAL OR SPECIAL
                  DAMAGES OF ANY DESCRIPTION, WHETHER ARISING OUT OF WARRANTY OR
                  CONTRACT, NEGLIGENCE OR OTHER TORT, OR OTHERWISE, INCLUDING,
                  WITHOUT LIMITATION, ANY DAMAGES RESULTING FROM LOST PROFITS OR
                  LOST BUSINESS OPPORTUNITY.

         10.4.    Survival. All of the representations, warranties, and
                  indemnifications made in this Agreement and all terms and
                  provisions hereof intended to be observed and performed by the
                  parties after the termination hereof, including the
                  obligations of confidentiality, shall survive such termination
                  and continue thereafter in full force and effect.

         10.5.    Complete Agreement. This Agreement constitutes the entire
                  agreement of the parties with respect to the subject matter
                  described in this Agreement and shall supersede all previous
                  negotiations, commitments or writings regarding such subject
                  matter, including the December Agreement.

         10.6.    Waiver, Discharge, etc. This Agreement may not be released,
                  discharged, abandoned, changed or modified in any manner,
                  except by an instrument in writing signed on behalf of each of
                  the parties to this Agreement by their duly authorized
                  representatives. The failure of either party to enforce at any
                  time any of the provisions of this Agreement shall in no way
                  be construed to be a waiver of any such provision, nor in any
                  way to affect the validity of this Agreement or any part of it
                  or the right of either party after any such failure to enforce
                  each and every such provision. No waiver of any breach of this
                  Agreement shall be held to be a waiver of any other or
                  subsequent breach.

         10.7.    Applicable Law. This Agreement shall be governed by, and
                  interpreted in accordance with the laws of the State of New
                  York.

         10.8.    Successors and Assigns. This Agreement shall be binding upon
                  and inure to the benefit of the parties to this Agreement and
                  their successors or assigns, provided that, except as
                  otherwise provided herein, the rights and obligations of
                  either party under this Agreement may not be assigned without
                  the written consent of the other party, which consent shall
                  not be unreasonably withheld.

         10.9.    Execution in Counterparts. This Agreement may be executed in
                  one or more counterparts, all of which shall be considered one
                  and the same agreement, and shall become a binding agreement
                  when one or more counterparts have been signed by each party
                  and delivery to the other party.

         10.10.   Titles and Headings; Construction. The titles and headings to
                  Sections herein are inserted for the convenience of reference

                                       14
<PAGE>
                  only and are not intended to be a part of or to affect the
                  meaning or interpretation of this Agreement. This Agreement
                  shall be construed without regard to any presumption or other
                  rule requiring construction hereof against the party causing
                  this Agreement to be drafted.

         10.11.   Benefit. Nothing in this Agreement, expressed or implied, is
                  intended to confer on any person other than the parties to
                  this Agreement or their respective successors or assigns, any
                  rights, remedies, obligations or liabilities under or by
                  reason of this Agreement.

         10.12.   Notices. Any notice or other communication required or
                  permitted under this Agreement shall be in writing and shall
                  be deemed to have been given, when received, if personally
                  delivered or delivered by telegram, telex or facsimile, or,
                  when deposited, if placed in the U.S. Mails for delivery by
                  registered or certified mail, return receipt requested,
                  postage prepaid and addressed to the appropriate party at the
                  addresses set forth on the first page of this Agreement.
                  Addresses may be changed by written notice given pursuant to
                  the provisions of this paragraph; however, any such notice
                  shall not be effective, if mailed, until five (5) working days
                  after depositing in the U.S. Mails or when actually received,
                  whichever occurs first.

         10.13.   Severability. If any provision of this Agreement is held
                  invalid by a court of competent jurisdiction, the remaining
                  provisions shall nonetheless be enforceable according to their
                  terms. Further, if any provision is held to be overbroad as
                  written, such provision shall be deemed amended to narrow its
                  application to the extent necessary to make the provision
                  enforceable according to applicable law and shall be enforced
                  as amended.

         10.14.   Execution of Further Documents. Each party agrees to execute
                  and deliver without further consideration any further
                  applications, licenses, assignments or other documents, and to
                  perform such other lawful acts as the other party may
                  reasonably require to fully secure and/or evidence the rights
                  or interests herein.

11.      ADDITIONAL AGREEMENTS

         11.1     Reports to PE. Newco shall inform PE from time to time at PE's
                  request made no more often than one each calendar month unless
                  Newco otherwise agrees, in such level of detail as PE may from
                  time to time specify, of any and all of research and
                  development activities undertaken or carried out and
                  developments and progress made in developing technology or
                  conceiving new inventions, or applying technology or
                  inventions to products and potential products, by or under the

                                       15
<PAGE>

                  direction of Newco during the immediately preceding month, and
                  generally keeping PE up to date on the financial state and the
                  business and technological affairs and progress of Newco. All
                  such information will be deemed confidential information of
                  Newco, except to the extent it is generally available to the
                  public or becomes generally available to the pubic through no
                  act or failure to act of PE, or PE can demonstrate it
                  possessed prior to Newco's disclosure to PE. Such reports will
                  be oral, unless otherwise requested by PE. Newco shall also
                  make a senior officer knowledgeable about Newco's research and
                  development efforts and technical research reasonably
                  available to PE to respond to inquiries from PE about
                  technical research and development activities. Such officer,
                  and his designees, shall respond to PE reasonable inquires
                  made from time to time by PE.

         11.2     Right of First Negotiation. During the five (5) year period
                  commencing with the date of this agreement, Newco shall not
                  grant any rights in or to any PE Aggregate Licensed Technology
                  to any third party, or enter into any agreement or arrangement
                  with any third party for the manufacture, use, sale or other
                  distribution of any product that incorporates or uses, or was
                  manufactured using, any PE Aggregate Licensed Technology or
                  the manufacture, use or sale of which would constitute, but
                  for the license granted to Newco pursuant to this Agreement,
                  an infringement of a claim of Patent Rights or "Patent Rights"
                  as defined in the Quantech License Agreement, or make a
                  proposal or enter into a letter or intent setting forth
                  possible terms or conditions as to any such grant, agreement
                  or arrangement, without first notifying PE in writing of the
                  proposed grant, agreement or arrangement (a "Proposed
                  Agreement Notice") and, if PE notifies Newco in writing within
                  forty five (45) days of its receipt of such notice from Newco
                  that it desires to negotiate with Newco regarding the grant of
                  such rights or entering into such an agreement or arrangement,
                  entering into negotiations with PE with respect to the grant
                  of such rights to or the entering into such an arrangement or
                  agreement with PE. Each Proposed Agreement Notice will
                  describe the proposed grant, agreement or arrangement in
                  reasonable detail. Newco agrees that it will not grant any
                  rights described in a Proposed Agreement Notice to any third
                  party, or enter into any agreement or other arrangement
                  described in such notice, with a third party except during the
                  180 day period commencing 60 days after the receipt by PE of
                  such notice and ending 240 days after the date of such receipt
                  (a "Third Party Agreement Period"). If the grant of rights is
                  not made, or such agreement or arrangement not entered into,
                  within said 180 day period, the rights contained herein shall
                  be reinstated as to all future grants of rights, agreements or
                  arrangements covering any of the prospective grants,
                  agreements or arrangements described in the Proposed Agreement
                  Notice. Nothing herein contained shall be deemed to prevent
                  Newco from discussing possible terms of any such proposed
                  grant of rights, agreement or arrangement with a third party,
                  provided that Newco does not make a proposal, enter into a
                  letter of intent or execute a binding agreement with respect

                                       16
<PAGE>

                  thereto except during the Third Party Agreement Period
                  applicable thereto. As used herein the term "third party"
                  includes, without limitation, any direct or indirect parent
                  company, direct or indirect subsidiary or any affiliate of
                  Newco, except solely PE.

         11.3     Right of Sublicense to EG&G. Notwithstanding anything
                  contained in this Agreement to the contrary, to enable the
                  implementation of agreements in principle entered into between
                  Quantech, PE and EG&G, Inc. in connection with the sale of
                  PE's Analytical Instruments Division to EG&G, Newco shall have
                  the right, if requested by EG&G on or before February 1, 2000,
                  to sublicense exclusively (even as to Newco) to EG&G all of
                  the rights and technology licensed to Newco pursuant to
                  Sections 2.1 and 2.2 of this Agreement in the fields of (i)
                  food and beverages, (ii) environmental and (iii) chemical and
                  industrial, but not in any other field, to make, have made for
                  it, use, and sell Licensed Products and Quantech Licensed
                  Products throughout the Territory in such fields. Newco agrees
                  that it shall only grant such rights and technology to EG&G
                  pursuant to a sublicense agreement substantially similar in
                  all substantive respects to the Quantech License Agreement
                  that has been approved in advance by PE, and that Newco shall
                  not permit any amendment to such sublicense agreement without
                  the consent of PE. In the event that EG&G does not request
                  such sublicense on or before February 1, 2000, Newco shall be
                  under no obligation to sublicense any such rights and
                  technology to EG&G.

IN WITNESS WHEREOF, each of the parties has caused this Agreement to be executed
in the manner appropriate to each, effective as of the date first above written.
