    6.2  Royalties shall be payable on LICENSED PRODUCTS and LICENSED METHODS
         covered by both pending patent applications and issued patents.

    6.3  Royalties accruing to the REGENTS shall be paid to the REGENTS
         semi-annually on or before the following dates of each calendar year:

              May 31 for the period ending March 31

              November 30 for the period ending September 30

    6.4  LICENSEE shall pay to the REGENTS a minimum annual royalty of $[*]
         on or before October 1 for each year for the life of this

          Agreement. The first minimum annual royalty will be payable on or
          before October 1, 1996. This minimum annual royalty will be credited
          against the earned royalty due and owing for the next twelve months
          ending on September 30 of each year.

     6.5  All royalties due the REGENTS shall be payable in United States funds
          collectible at par in San Francisco, California. When LICENSED
          PRODUCTS are sold for monies other than United States dollars, the
          earned royalties will first be determined in the foreign currency of
          the country in which the LICENSED PRODUCTS were licensed and then
          converted into equivalent United States funds. The exchange rate will
          be that rate quoted in the Wall Street Journal on the last business
          day of the reporting period.

     6.6. Earned royalties on licensed distribution of LICENSED PRODUCTS
          occurring in any country outside the United States shall not be
          reduced by any taxes, fees, or other charges imposed by the government
          of such country on the remittance of royalty income. The LICENSEE
          shall also be responsible for all bank transfer charges.

     6.7  LICENSEE shall make all payments under this Agreement to "The Regents
          of the University of California" and forward it to REGENTS at the
          address shown in Article 23.

     6.8  In the event that any patent or any claim thereof included within the
          REGENTS' PATENT RIGHTS expires or shall be held invalid in a final
          decision by a court of competent jurisdiction and last resort and from
          which no appeal has been or can be taken, all obligation to pay
          royalties for LICENSED PRODUCTS based on, covered by, or made using
          such patent or claims or any claims patentably indistinct therefrom
          shall cease as of the date of such expiration or final decision.
          LICENSEE shall not, however, be relieved from paying any royalties for
          LICENSED PRODUCTS that accrued before such expiration or decision or
          that are based on another valid patent or claim not expired or
          involved in such decision.

     6.9  No royalties will be collected or paid hereunder on LICENSED PRODUCTS
          distributed to or used by the United States Government.

THE SYMBOL "[*]" IS USED TO INDICATE THAT A PORTION OF THE EXHIBIT HAS BEEN
OMITTED AND FILED SEPARATELY WITH THE COMMISSION. CONFIDENTIAL TREATMENT HAS
BEEN REQUESTED WITH RESPECT TO THE OMITTED PORTIONS.


          LICENSEE agrees to reduce the amount charged for LICENSED PRODUCTS
          distributed to the United States Government by an amount equal to the
          royalty for such LICENSED PRODUCTS otherwise due the REGENTS as
          provided herein.

7.   DUE DILIGENCE

     7.1  LICENSEE, upon execution of this Agreement, shall use diligent
          commercial efforts to proceed with the development, manufacture, and
          distribution under license of LICENSED PRODUCTS and shall use diligent
          commercial efforts to market them in quantities sufficient to meet the
          market demand. LICENSEE shall be entitled to exercise prudent and
          reasonable business judgment in meeting its due diligence obligations
          hereunder.

     7.2  LICENSEE specifically commits to achieving the following objectives in
          its due diligence activities hereunder:

          (a)  Initiate automated kit development in the fourth calendar quarter
               of 1995.

          (b)  Full product automated ET-primer kit availability in the first
               six months of 1996.

          (c)  First product introduction by September 1, 1996.
     7.3  If LICENSEE is unable to meet any of its due diligence obligations set
          forth in Article 7.2, then LICENSEE shall so notify REGENTS of failure
          to perform. LICENSEE shall have the right and option to extend the
          target date of such due diligence obligation for a period of six (6)
          months upon the payment of $[*] within thirty (30) days of the
          extension date for each six (6) months extension option exercised by
          LICENSEE. Each target date may be extended two times upon payment of
          the $[*] extension fee. These payments are creditable toward the
          minimum royalty payments specified in Article 6.4. Should LICENSEE opt
          not to extend the obligation or fail to meet it by the extended target
          date, then REGENTS shall have the right and option either to terminate
          this Agreement or to reduce the LICENSEE's

U.C. Case No.: B94-034, B96-001       Page 9        Proprietary and Confidential
Amersham                                      University of California, Berkeley
<PAGE>   13
          exclusive license to a non-exclusive royalty bearing license. This
          right, if exercised by REGENTS, supersedes the rights granted in
          Article 3. The right to terminate this Agreement or reduce LICENSEE's
          exclusive license granted hereunder to a non-exclusive license shall
          be REGENTS' sole remedy for breach of Article 7. However, if LICENSEE
          is unable to perform any of the due diligence obligations set forth
          in Article 7.2 due to hardships beyond LICENSEE's control, including
          but not limited to delay while LICENSEE is obtaining a license
          covering patents owned by a third party, while LICENSEE has
          demonstrated diligent commercial efforts to perform these
          obligations, then REGENTS will extend the dates as appropriate (after
          conferring with LICENSEE in good faith and, in any event, on at least
          a day to day basis) in writing to LICENSEE, and REGENTS shall not
          terminate this Agreement or reduce LICENSEE's exclusive license to a
          non-exclusive license.

     7.4  At the request of either party, any controversy or claim arising out
          of or relating to the diligence provisions of Article 7.2 shall be
          settled by arbitration conducted in San Francisco, CA in accordance
          with the then current Licensing Agreement Arbitration Rules of the
          American Arbitration Association. Judgment upon the award rendered by
          the arbitrator(s) shall be binding on the parties and may be entered
          by either party in the court or forum, state or federal, having
          jurisdiction. In determination of due diligence, the arbitrator may
          determine solely the issues of fact or law with respect to
          termination of LICENSEE's or REGENTS' respective rights under this
          Agreement but shall not have the authority to award monetary damages
          or grant equitable relief.

     7.5  To exercise either the right to terminate this Agreement or to reduce
          the license to a non-exclusive license for lack of diligence required
          in Article 7.2, REGENTS must give LICENSEE written notice of the
          deficiency. The LICENSEE thereafter has sixty (60) days to cure the
          deficiency or to request arbitration. If REGENTS has not received a
          written request for arbitration or satisfactory tangible evidence
          that the deficiency has been cured by the end of the sixty (60) day
          period, then REGENTS may, at its option, either terminate the
          Agreement or reduce LICENSEE's exclusive license to a non-exclusive
          license by giving written notice to LICENSEE. These notices shall be
          subject to Article 23 (Notices).

8.   PROGRESS AND ROYALTY REPORTS

     8.1  Beginning March 1, 1996, and semi-annually thereafter, LICENSEE shall
          submit to REGENTS a progress report covering LICENSEE's activities
          related to the development and testing of all LICENSED PRODUCTS and
          the obtaining of the governmental approvals necessary, if any, for
          marketing in the United States. These progress reports shall be made
          for all LICENSED PRODUCTS until the first commercial sale of such
          LICENSED PRODUCTS occurs in the United States.

     8.2  LICENSEE also agrees to report to REGENTS in its immediately
          subsequent progress and royalty reports, the date of first commercial
          distribution under license of LICENSED PRODUCTS.

     8.3  After the first commercial sale of LICENSED PRODUCTS anywhere in the
          world, LICENSEE will make quarterly royalty reports to REGENTS within
          sixty (60) days after the quarters ending March 31, June 30,
          September 30, and December 31, of each year. Each such royalty report
          shall include at least the following:
          (a)  The number of LICENSED PRODUCTS manufactured and the number sold;
          (b)  Gross revenue for LICENSED PRODUCTS;
          (c)  NET SALES pursuant to Article 2.4;
          (d)  Total royalties due REGENTS; and
          (e)  Names and addresses of any new sublicensees along with a summary
               of the material terms of each new sublicense agreement entered
               into during the reporting quarter.

     8.4  If no distribution under license of LICENSED PRODUCTS has been made
          during the report period, a statement to this effect is required.

9.   BOOKS AND RECORDS

     9.1  LICENSEE shall keep full, true, and accurate books of accounts
          containing all particulars that may be necessary for the purpose of
          showing the amount of royalties payable to REGENTS. Said books of

<PAGE>   15
          accounts shall be kept at LICENSEE's principal place of business or
          the principal place of business of the appropriate division of
          LICENSEE to which this Agreement relates. Said books and the
          supporting data shall be open at all reasonable times during normal
          business hours upon reasonable notice, for three (3) years following
          the end of the calendar year to which they pertain, to the inspection
          and audit by an independent certified public accountant retained by
          REGENTS for the purpose of verifying LICENSEE's royalty statement or
          compliance in other respects with this Agreement. Such independent
          certified accountant shall be bound to hold all information in
          confidence except as necessary to communicate LICENSEE's
          non-compliance with this AGREEMENT to REGENTS.

    9.2   The fees and expenses of REGENT's representatives performing such an
          examination shall be borne by REGENTS. However, if an error in
          underpaid royalties to REGENTS of more than five percent (5%) of the
          total royalties due for any year is discovered, then the fees and
          expenses of these representatives shall be borne by LICENSEE.

10. LIFE OF THE AGREEMENT

    10.1  Unless otherwise terminated by the operation of law or by acts of the
          parties in accordance with the terms of this Agreement, this Agreement
          shall be in force from the effective date recited on page one and
          shall remain in effect for the life of the last-to-expire patent
          licensed under this Agreement.

    10.2  In the event this Agreement is terminated for any reason whatsoever
          not including expiration, LICENSEE shall provide to REGENTS, in
          writing and at no cost to REGENTS, all technical information, data,
          and know how that has been reduced to some tangible form and developed
          by LICENSEE and directly relating to the LICENSED PRODUCTS, but
          specifically excluding proprietary technology belonging to LICENSEE,
          within ninety (90) days of such termination. LICENSEE hereby grants to
          REGENTS a non-exclusive right to use, and sublicense others the right
          to use the technical information, data, and know-how, and LICENSEE
          reserves the right to use, sublicense others to use, and otherwise
          exploit all such technical information,

<PAGE>   16
          data and know-how to the extent that such use does not conflict with
          the other provisions of this Agreement.

     10.3 Any termination of this Agreement shall not affect the rights and
          obligations set forth in the following articles:

               Article 4      Sublicenses
               Article 9      Books and Records
               Article 10     Life of the Agreement

                              Hand Upon Termination
               Article 16     Use of Names and Trademarks
               Article 19     Indemnification
               Article 24     Late Payments
               Article 26     Confidentiality

     10.4 Any termination of this Agreement shall not relieve LICENSEE of its
          obligation to pay any monies due or owing at the time of such
          termination and shall not relieve any obligations, of either party to
          the other party, established prior to termination.

11.  TERMINATION BY REGENTS

     If LICENSEE should violate or fail to perform any term or covenant of this
     Agreement, then REGENTS may give written notice of such default ("Notice of
     Default") to LICENSEE. If LICENSEE should fail to repair such default
     within sixty (60) days of the effective date of such notice, REGENTS shall
     have the right to terminate this Agreement and the licenses herein by a
     second written notice ("Notice of Termination") to LICENSEE. If a Notice of
     Termination is sent to LICENSEE, this Agreement shall automatically
     terminate on the effective date of such notice. Such termination shall not
     relieve LICENSEE of it obligation to pay any royalty or license fees owing
     at the time of such termination and shall not impair any accrued rights of
     REGENTS. These notices shall be subject to Article 23 (Notices).

<PAGE>   17
     12.1 LICENSEE shall have the right at any time to terminate this Agreement
          in whole or as to any portion of REGENTS' PATENT RIGHTS by giving
          notice in writing to REGENTS. Such notice of termination shall be
          subject to Article 23 (Notices) and termination of this Agreement
          shall be effective ninety (90) days from the effective date of such
          notice.

     12.2 Any termination pursuant to the above paragraph shall not relieve
          LICENSEE of any obligation or liability accrued hereunder prior to
          such termination or rescind anything done by LICENSEE or any payments
          made to REGENTS hereunder prior to the time such termination becomes
          effective, and such termination shall not affect in any manner any
          rights of REGENTS arising under this Agreement prior to such
          termination.

13.  DISPOSITION OF PRODUCTS ON HAND UPON TERMINATION

     Upon termination of this Agreement LICENSEE shall have the privilege of
     disposing of all previously made or partially made LICENSED PRODUCTS, but
     no more, within a period of one hundred and twenty (120) days following the
     effective date of termination, provided, however, that the sale of such
     LICENSED PRODUCTS shall be subject to the terms of this Agreement
     including, but not limited to, the payment of royalties at the rate and at
     the time provided herein and the rendering of reports thereon.
14.   PATENT PROSECUTION AND MAINTENANCE
     14.1 REGENTS shall diligently prosecute and maintain the United States and
          foreign patent applications and patents under REGENTS' PATENT RIGHTS
          using counsel of its choice, provided that the continued use of such
          counsel at any point in the patent prosecution process subsequent to
          initial filing of a U.S. patent application covering the INVENTION,
          including preparation and filing of divisions, substitutions,
          extensions, continuation-in-part applications, and corresponding
          foreign applications, shall be subject to the approval of LICENSEE.
          REGENTS shall promptly provide LICENSEE with copies of all relevant
          documentation so that LICENSEE may be currently informed and apprised
          of the continuing prosecution and LICENSEE

U.C. Case No.: B94-034, B96-001    Page 14    Proprietary and Confidential
Amersham                                      University of California, Berkeley
<PAGE>   18
          agrees to keep this documentation confidential in accordance with
          Article 26 herein. LICENSEE may comment upon such documentation,
          provided, however, that if LICENSEE has not commented upon such
          documentation prior to the deadline for filing a response with the
          relevant government patent office, REGENTS shall be free to respond
          appropriately without consideration of LICENSEE's comments. LICENSEE
          and LICENSEE's patent counsel shall have the right to consult with
          patent counsel chosen by REGENTS.

     14.2 REGENTS shall use all reasonable efforts to prepare or amend any
          patent application to include claims reasonably requested by LICENSEE
          to protect the products contemplated to be sold, or methods or
          procedures to be practiced under this Agreement.

     14.3 Subject to Articles 14.4 and 14.6, all past, present, and future costs
          for preparing, filing, prosecuting, and maintaining all United States
          and foreign patent applications, and patents issuing thereon and
          contemplated by the executed Letter Agreement dated January 13, 1995,
          and this Agreement shall be borne by LICENSEE, so long as the licenses
          granted to LICENSEE herein are exclusive. If, however, REGENTS reduces
          the exclusive licenses granted herein to nonexclusive licenses
          pursuant to Articles 7.3, 7.4, or 7.5 and REGENTS grants additional
          license(s), the costs of preparing, filing, prosecuting and
          maintaining such patent applications and patents shall be divided
          equally among the licensed parties from the effective date of each
          subsequently granted license agreement.

     14.4 REGENTS shall file, prosecute and maintain, at the request of
          LICENSEE, patent applications and patents covered by REGENTS' PATENT
          RIGHTS in foreign countries, if available, and if LICENSEE so desires.
          LICENSEE must notify REGENTS within nine (9) months of the filing of
          the corresponding United States application of its decision to obtain
          foreign patents. The notice concerning foreign filing shall be in
          writing and must identify the countries desired. The absence of such a
          notice from LICENSEE to REGENTS within such nine (9) month period
          shall be considered an election not to secure foreign rights. REGENTS
          shall have the right to file patent applications at its own expense in
          any country which LICENSEE has

U.C. Case No.: B94-034, B96-001    Page 15    Proprietary and Confidential

<PAGE>   19
          not included in the list of desired countries and such application and
          resultant patents shall not be subject to this Agreement.

     14.5 All patents and patent applications under this Agreement shall be held
          in the name of REGENTS, and shall be subject to the terms and
          provisions hereof. REGENTS shall take into consideration LICENSEE's
          reasonable suggestions in the preparation and prosecution of REGENTS'
          PATENT RIGHTS covering the INVENTION in order to obtain the broadest
          claims and protection.

     14.6 LICENSEE's obligation to underwrite and to pay all domestic and
          foreign patent filing, prosecution, and maintenance costs shall
          continue for so long as this Agreement remains in effect, provided,
          however, that LICENSEE may terminate its obligations with respect to
          any given patent application or patent in any or all designated
          countries upon three (3) months written notice to REGENTS. REGENTS
          will use its best efforts to curtail patent costs when such a notice
          is received from LICENSEE. REGENTS may continue prosecution and/or
          maintenance of such application(s) or patent(s) at its sole
          discretion and expense; provided, however, that LICENSEE shall have no
          further right or licenses thereunder.

15.  MARKING

     Prior to the issuance of patents under REGENTS' PATENT RIGHTS, LICENSEE
     agrees to mark LICENSED PRODUCTS (or their containers or labels) made,
     sold, licensed or otherwise disposed of by it in the United States under
     the license granted in this Agreement with the words "Patent Pending," and
     following the issuance in the United States of one or more patents under
     REGENTS' PATENT RIGHTS, with the numbers of the REGENTS' PATENT RIGHTS.

16.  USE OF NAMES AND TRADEMARKS

     Nothing contained in this Agreement shall be construed as conferring any
     right to use in advertising, publicity or other promotional activities any
     name, trademark, trade name, or other designation of either party hereto
     (including any contraction, abbreviation, or simulation of any of the



U.C. Case No.: B94-034, B96-001    Page 16    Proprietary and Confidential

     foregoing). Unless required by law or consented to in writing by REGENTS,
     the use of the name "The Regents of the University of California" or the
     name of any University of California campus is expressly prohibited.

18.  PATENT INFRINGEMENT

     18.1  In the event that LICENSEE shall learn of the substantial
           infringement of any REGENTS' PATENT RIGHTS under this Agreement,
           LICENSEE shall promptly inform REGENTS with reasonable evidence of
           such infringement. Both parties to this Agreement agree that during
           the period and in a jurisdiction where LICENSEE has exclusive rights
           under this Agreement, neither will notify a third party of the
           infringement without first obtaining consent of the other party,
           which consent shall not be unreasonably denied. Both parties, in
           cooperation with each other shall agree on a mutually acceptable
           approach to terminate such infringement without litigation.

     18.2  LICENSEE may request that REGENTS take legal action against the
           infringement. Such request shall be made in writing and shall include
           reasonable evidence of such infringement and damages to LICENSEE. If
           the infringing activity has not been abated within ninety (90) days
           following the effective date of such request, REGENTS shall have the
           right to:
           (a)  Commence suit on its own account; or
           (b)  Refuse to participate in such suit.
           REGENTS shall give notice of its election in writing to LICENSEE
           within ninety (90) days after receiving such request from LICENSEE
           and absent refusal to participate in such suit, shall commence suit
           promptly thereafter. LICENSEE shall have the right to join or
           intervene at its own expense in any such suit commenced by REGENTS.
           LICENSEE may bring suit for patent infringement if, and only if,
           REGENTS elects not to commence suit and if the infringement occurred
           during the period and in a jurisdiction where LICENSEE had exclusive
           rights under this Agreement. However, in the event LICENSEE elects to
           bring suit in accordance with this paragraph, REGENTS may thereafter
           join such suit at its own expense.

     18.4 Each party agrees to cooperate with the other in legal proceedings
          instituted hereunder but at the expense of the party on account of
          whom suit is brought. Such legal proceedings shall be controlled by
          the party bringing the action, except that REGENTS may be represented
          by counsel of its choice, at its sole expense, in any action brought
          by LICENSEE and LICENSEE may be represented by counsel of its choice,
          at its sole expense, in any action brought by REGENTS.

19.  INDEMNIFICATION

     LICENSEE agrees, and agrees to require its sublicensees, to indemnify, hold
     harmless, and defend REGENTS and its officers, employees, and agents;
     sponsor(s) of the research that led to the INVENTION; and the inventors of
     the patents and patent applications in REGENTS' PATENT RIGHTS and their
     employees against any and all liability, claims, suits, losses, damages,
     costs, fees, and expenses for death, illness, personal injury, property
     damage, and improper business practices arising out of the manufacture,
     use, sale, lease or other disposition of the INVENTION, REGENTS' PATENT
     RIGHTS, or LICENSED PRODUCTS by LICENSEE, by its sublicensees, or each of
     their customers except to the extent such arises from the negligence or
     default of REGENTS whereupon the obligation to indemnify contained in this
     clause should be reduced in proportion to such negligence or default.


20.  EXPORT CONTROLS

     LICENSEE understands that REGENTS are subject to United States laws and
     regulations (including the Arms Export Control Act, as amended, and the
     Export Administration Act of 1979), controlling the export of technical
     data, computer software, laboratory prototypes and other commodities, and
     REGENTS' obligations under this Agreement are contingent on compliance with
     such laws and regulations. The transfer of certain technical data and
     commodities may require a license from the cognizant agency of the United

<PAGE>   23
     States Government and/or written assurances by LICENSEE that LICENSEE shall
     not export such technical data and/or commodities to certain foreign
     countries without prior approval of such agency. REGENTS neither represent
     that a license shall not be required nor that, if required, it shall be
     issued.

21.  FOREIGN GOVERNMENTAL APPROVAL OR REGISTRATION

     If this Agreement or any associated transaction is required by the law of
     any nation to be either approved or registered with any governmental
     agency, LICENSEE shall assume all legal obligations to do so.

22.  ASSIGNMENT

     This Agreement is binding upon and shall inure to the benefit of REGENTS,
     its successors and assigns, provided, however, this Agreement shall be
     personal to LICENSEE and AFFILIATES and assignable by LICENSEE only with
     the written consent of REGENTS, which consent shall not be unreasonably
     withheld, except that LICENSEE may freely assign this Agreement to an
     acquirer of all or substantially all of LICENSEE's stock, assets or
     business.

23.  NOTICES

24.  LATE PAYMENTS

     In the event royalty payments or fees are not received by REGENTS when due,
     LICENSEE shall pay to REGENTS interest charges at a rate of ten percent
     (10%) per annum. Such interest shall be calculated from the date payment
     was due until actually received by REGENTS.

25.  WAIVER

     25.1 The failure of either party to assert a right hereunder or to insist
          upon compliance with any term or condition of this Agreement shall not
          constitute a waiver of that right or excuse a similar subsequent
          failure to perform any such term or condition by the other party.

     25.2 None of the terms, covenants, and conditions of this Agreement can be
          waived except by the written consent of the party waiving compliance.

26.  CONFIDENTIALITY

     26.1 LICENSEE and REGENTS respectively shall hold the other party's
          proprietary business, terms of this Agreement, patent prosecution
          material, and technical information and other proprietary information

          the same degree of care as it exercises to protect its own data and
          license agreements of a similar nature.

     26.2 Nothing contained herein shall in any way restrict or impair the right
          of LICENSEE or REGENTS to use, disclose, or otherwise deal with any
          information or data which:

          (a)  at the time of disclosure to a receiving party is generally
               available to the public or thereafter becomes generally available
               to the public by publication or otherwise through no act of the
               receiving party;

     (c)  is independently made available to the receiving party without

26.3 It is understood that REGENTS shall be free to release to the inventors and
     senior administrators employed by REGENTS the terms and conditions of this
     Agreement upon their request. If such release is made, REGENTS shall inform
     such employees of the confidentiality obligations set forth above and shall
     request and use its best efforts to ensure that they do not disclose such
     terms and conditions to others. It is further understood that should a
     third party inquire whether a license to REGENTS' PATENT RIGHTS is
     available, REGENTS may disclose the existence of this Agreement and the
     extent of the grant in Article 3 to such third party, but shall not
     disclose the name of LICENSEE, except where REGENTS are required to release
     information under either the California Public Records Act or other
     applicable law, provided REGENTS shall give prior written notice to
     LICENSEE of such disclosure.

26.4 LICENSEE and REGENTS agree to destroy or return to the disclosing party
     proprietary information received from the other in its possession within
     fifteen (15) days following the effective date of termination of this
     Agreement. However, each party may retain one copy of proprietary
     information of the other solely for archival purposes in non-working files
     for the sole purpose of verifying the ownership of the proprietary
     information, provided such proprietary information shall be subject to the
     confidentiality provisions set forth in Article 26.1. LICENSEE and REGENTS
     agree to provide each other, within thirty (30) days following termination
     of this Agreement, with a written notice that proprietary information has
     been returned or destroyed.

26.5 The terms of this Article 26 (Confidentiality) shall expire in five (5)
     years from the official date of termination of this Agreement.

27.  FORCE MAJEURE

     The parties to this Agreement shall be excused from any performance
     required hereunder if such performance is rendered impossible or unfeasible

     control, including, without limitation, war, riot, and insurrection; laws,
     proclamations, edicts, ordinances, or regulations; strikes, lockouts, or
     other serious labor disputes; and floods, fires, explosions, or other
     natural disasters. When such events have abated, the parties' respective
     obligations hereunder shall resume.

     provision of this Agreement shall be determined to be invalid or
