[INTEG INCORPORATED LOGOLOGO]

Dear Integ Shareholders:


    You are cordially invited to attend the special meeting of shareholders of
Integ Incorporated, to be held on January 23, 2001, at 10:00 a.m., at the
Minneapolis Marriott City Center, 30 South 7th Street, Minneapolis, Minnesota
55402. At the special meeting you will be asked to consider and vote upon a
proposal to approve an Agreement and Plan of Merger dated as of October 3, 2000,
as amended, pursuant to which Integ will be merged with and into Terrier
Acquisition Corp., a Delaware corporation and a wholly owned subsidiary of
Inverness Medical Technology, Inc., a Delaware corporation. Integ will become a
wholly owned subsidiary of Inverness as a result of the Merger.



    If the merger agreement is approved and the merger is subsequently
completed, each outstanding share of Integ common stock will be converted into
the right to receive Inverness common stock. The per share exchange ratio will
be determined as of the closing of the merger based on an exchange ratio
described in detail in this proxy statement and prospectus. Based on the number
of outstanding shares of Integ common stock, options and warrants on
December 13, 2000, and the average closing sale price of Inverness common stock
during the five trading days prior to such date, each share of Integ common
stock would be exchanged for approximately .1734 of an Inverness share, although
this number will change. You will receive cash, without interest, for any
fractional share of Inverness common stock that you would otherwise be entitled
to receive.



    Inverness common stock is traded on the American Stock Exchange under the
trading symbol "IMA," and on December 13, 2000, Inverness common stock closed at
$36.6875 per share.



    Before we can complete the merger, a majority of the shareholders of Integ
must vote on a specific proposal. This proposal involves the approval of the
merger agreement related to the merger. Only shareholders who hold shares of
Integ common stock at the close of business on December 13, 2000, will be
entitled to vote at the special meeting. Approval of the merger agreement
requires the affirmative vote of the holders of a majority of the issued and
outstanding shares of Integ common stock. Each share of Integ common stock is
entitled to one vote on all matters to come before the special meeting. The
Integ common stock constitutes the only class of Integ's capital stock entitled
to vote at the special meeting.


    YOUR BOARD OF DIRECTORS HAS CAREFULLY CONSIDERED THE TERMS AND CONDITIONS OF
THE MERGER AND UNANIMOUSLY AGREES THAT THE TERMS ARE FAIR TO, AND IN THE BEST
INTERESTS OF, OUR SHAREHOLDERS AND HAS APPROVED THE MERGER AGREEMENT AND
RECOMMENDS THAT YOU VOTE FOR APPROVAL OF THE MERGER AGREEMENT. U.S. Bancorp
Piper Jaffray Inc. provided to the board of directors a written opinion dated
October 3, 2000 to the effect that, as of that date, and based upon and subject
to the matters stated in the opinion, the merger consideration to be received by
holders of our common stock was fair, from a financial point of view, to our
common shareholders. U.S. Bancorp Piper Jaffray's written opinion is attached as
Annex B to the enclosed proxy statement and prospectus, and you should read it
carefully and in its entirety.

    Attached to this letter you will find a formal notice of the special meeting
and a proxy statement and prospectus. This proxy statement and prospectus
provides you with detailed information concerning Inverness, Integ and the
merger. Please give all of the information contained or incorporated by
reference in the proxy statement and prospectus your careful attention. IN
PARTICULAR, YOU SHOULD CAREFULLY CONSIDER THE DISCUSSION IN THE SECTION ENTITLED
"RISK FACTORS" ON PAGE 17 OF THIS PROXY STATEMENT AND PROSPECTUS, INCLUDING
THOSE RISK FACTORS THAT ARE INCORPORATED BY REFERENCE INTO THIS PROXY STATEMENT
AND PROSPECTUS. You may also obtain more information about Inverness and us from
documents we have filed with the Securities and Exchange Commission. If the
requisite holders of Integ common stock approve the merger agreement, it is
expected that the closing of the merger will occur soon after the special
meeting and after all of the other conditions to closing the merger are
satisfied.

    To vote your shares, you may use the enclosed proxy card or attend the
special shareholders meeting that will be held for this important vote.

    Thank you for your cooperation.

                                          Sincerely,

                                          /s/ Susan L. Critzer

                                          PRESIDENT AND CHIEF EXECUTIVE OFFICER

    NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES
COMMISSION HAS APPROVED OR DISAPPROVED THE SHARES OF INVERNESS COMMON STOCK TO
BE ISSUED IN THE MERGER OR DETERMINED IF THIS PROXY STATEMENT AND PROSPECTUS IS
ACCURATE OR ADEQUATE. ANY REPRESENTATION TO THE CONTRARY IS UNLAWFUL.


    This proxy statement and prospectus is dated December 15, 2000 and is first
being mailed to Integ shareholders on or about December 20, 2000.

                     QUESTIONS AND ANSWERS ABOUT THE MERGER

Q: WHAT IS THE PROPOSED TRANSACTION?

A: The proposed transaction contemplates that Integ will merge with and into a
    newly formed, wholly owned subsidiary of Inverness. The merged entity will
    survive the merger as a wholly owned subsidiary of Inverness.

Q: WHAT WILL I RECEIVE IN THE MERGER?

A: Each share of Integ common stock you hold immediately prior to the effective
    time of the merger will be converted into the right to receive a specific
    number of shares of Inverness common stock. This specific number of shares
    of Inverness common stock to be issued for each share of Integ common stock,
    which is called the exchange ratio, is tied to a formula described in more
    detail in the summary of the merger beginning on page 3. In general, the
    exchange ratio will be calculated so that a total of 1,900,000 shares of
    Inverness common stock, net of exercise amounts attributable to options and
    warrants of Integ that are outstanding as of the effective time, will be
    issued to:

    - existing holders of shares of Integ common stock,

    - holders of options to purchase shares of Integ common stock, upon exercise
      of the options, and

    - holders of warrants to purchase Integ common stock, upon exercise of the
      warrants.

    Accordingly, Inverness will be assuming all outstanding Integ options and
    warrants.

    You will not receive any fractional shares. Instead, you will receive cash
    in an amount equal to the average closing price for a share of Inverness
    common stock for the five-day trading period immediately preceding the
    effective date of the merger, multiplied by the appropriate fraction.

Q: IS THE EXCHANGE RATIO CURRENTLY DETERMINABLE?

A: No. Because the formula is dependent on certain factors not determinable
    until immediately prior to the effective time of the merger, including the
    average closing sale price of Inverness common stock for the five trading
    days immediately preceding the effective time of the merger and the number
    of options and warrants to purchase Integ common stock outstanding at the
    effective time, the exact number of shares you will receive for each Integ
    share cannot be determined at this time.


    The average closing sale price of Inverness common stock for the
    five trading days prior to December 13, 2000, the record date, was $34.0752
    per share. Accordingly, factoring in the exercise prices of all outstanding
    Integ options and warrants as of December 13, 2000, if the merger were to
    occur on such date, each share of Integ common stock would be converted into
    the right to receive approximately .1734 shares of Inverness common stock.


Q: WILL I BE ABLE TO TRADE THE INVERNESS COMMON STOCK THAT I RECEIVE IN THE
    MERGER?

A: Yes. Inverness intends to list the Inverness common stock on the American
    Stock Exchange under the symbol "IMA".

Q: DO I HAVE APPRAISAL RIGHTS WITH RESPECT TO THE TRANSACTIONS?

A: Holders of Integ common stock are entitled to appraisal rights under sections
    302A.471 and 302A.473 of the Minnesota Business Corporation Act.

Q: WHAT HAPPENS IF THE MERGER IS NOT COMPLETED?

A: If the merger is not completed both companies will continue as independent
    companies. Integ may be required to pay a termination fee and certain
    expenses to Inverness under the merger agreement if the merger is not
    completed for certain reasons as discussed in this proxy statement and
    prospectus.

Q: WHEN WILL THE TRANSACTIONS BE COMPLETED?

A: The shareholders of Integ must approve the merger agreement at the special
    meeting. Some of Integ's principal shareholders, including all of Integ's
    directors and executive officers, representing a total of approximately
    15.4% of the outstanding

                                       1
<PAGE>
    Integ common stock on October 3, 2000, have entered into a voting agreement
    to vote all of their shares of Integ common stock in favor of the merger
    agreement.

    We plan to complete the transactions as soon as possible after the special
    meeting, subject to the satisfaction or waiver of other conditions to the
    transactions, some of which are not in our control. Although we cannot
    predict when our conditions will be satisfied, we hope to complete the
    transactions no later than in the first quarter of 2001.

Q: SHOULD I SEND IN MY STOCK CERTIFICATES NOW?

A: No. If the merger is completed, you will receive written instructions for
    exchanging your shares of Integ common stock for shares of Inverness common
    stock. In the meantime, you should retain your certificates as the Integ
    common stock certificates are still valid. Please do not send in your stock
    certificates with your proxy.

Q: WHAT DO I NEED TO DO NOW?

A: You should carefully read and consider the information contained or
    incorporated by reference in this proxy statement and prospectus, including
    its annexes. It contains important information about Integ and Inverness. It
    also contains important information about what the boards of directors of
    Integ and Inverness considered in evaluating the transactions.

    You should then complete and sign your proxy card and return it in the
    enclosed return envelope as soon as possible so that your shares will be
    represented at the special meeting. If you sign and send in your proxy, but
    do not indicate how you want to vote, we will count your proxy as a vote FOR
    approval of the merger agreement. If you abstain from voting or do not vote,
    it will have the effect of a vote against the merger agreement.

Q: CAN I CHANGE MY VOTE AFTER I HAVE MAILED MY SIGNED PROXY CARD?

A: Yes. You can change your vote at any time before your proxy is voted at the
    special meeting. You can do this in one of three ways:

    - you can send a written notice stating that you revoke your proxy to Integ
      at the address listed below;

    - you can complete and submit a new proxy card, dated a later date than the
      first proxy card and send it to Integ at the address listed below. The new
      proxy card will automatically replace any earlier dated proxy card that
      you returned; or

    - you can attend the special meeting and vote in person.

    Your attendance at the special meeting will not, however, by itself revoke
    your proxy; you must also vote at the special meeting.

    You should send any notice of revocation or your completed new proxy card,
    as the case may be, to Integ at the following address:

        Integ Incorporated
        c/o Wells Fargo Shareowner Services
        P.O. Box 64873
        St. Paul, Minnesota 55164-9397

Q: IF MY SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER VOTE MY
    SHARES FOR ME?

A: No. Your broker will vote your shares only if you provide instructions to
    your broker on how to vote. You should contact your broker and ask what
    directions your broker will need from you. Your broker will not be able to
    vote your shares without instructions from you, and therefore the failure to
    give these instructions will have the effect of a vote against the merger.

Q: ARE THERE ANY RISKS I SHOULD CONSIDER IN DECIDING WHETHER I VOTE FOR THE
    MERGER?

                                 THE COMPANIES

INVERNESS (SEE PAGE 60)

    The principal executive office of Inverness Medical Technology, Inc., a
Delaware corporation, is located at 200 Prospect Street, Waltham, Massachusetts
02453, and its telephone number is (781) 647-3900.

    Inverness develops, manufactures and markets innovative products focused
primarily on diabetes self-management. Inverness' principal products are
advanced electrochemical blood glucose monitoring systems that are used by
people with diabetes to determine their glucose levels in order to manage their
disease. Inverness' systems are accurate, small, fast and easy to use. They
utilize Inverness' proprietary biosensor test strips, which quickly draw blood
into the strip, require only a small sample and provide users with the option of
sampling from the forearm, thus avoiding the need for finger sticking. Inverness
believes that the increased convenience and comfort offered by its systems will
encourage more frequent blood glucose testing, an essential element of effective
diabetes self-management. Inverness introduced its first generation
electrochemical system in early 1998 and has shipped over 1.4 million meters
through September 30, 2000. Meter shipments for this system more than doubled in
the nine months ended September 2000 as compared to the same period in 1999.
Inverness recently received FDA clearance for its second generation
electrochemical system, which it expects to begin shipping in the fourth quarter
of 2000. This system utilizes Inverness' latest proprietary test strip with a
reduced blood sample requirement of just one microliter, and features the
fastest test time of any commercially available system at five seconds,
providing enhanced convenience and comfort. Inverness uses its diabetes
expertise to design and manufacture low-cost alternative test strips for use in
leading brand glucose meters made by other manufacturers. Inverness also markets
a full family of ancillary diabetes supplies such as syringes, lancets, glucose
tablets, and specialty skin creams. In addition to its diabetes products,
Inverness sells women's health products, including home pregnancy detection
tests, ovulation prediction tests and a line of nutritional supplements.

    Inverness seeks to maximize market penetration of its products through
strategic partnerships and through its wholesale and retail distribution
networks. Inverness has a global distribution agreement with LifeScan, a
subsidiary of Johnson & Johnson, under which it develops and manufactures, and
LifeScan markets, its electrochemical blood glucose monitoring systems.
Inverness' first and second generation electrochemical systems are being
marketed by LifeScan as the ONE TOUCH-Registered Trademark-
FastTAKE-Registered Trademark- and ONE TOUCH-Registered Trademark- Ultra.
Inverness believes that its systems, which are the only electrochemical systems
offered by LifeScan, are well positioned to capture an increasing market share.
Further, its agreement with LifeScan contemplates that it will develop and
manufacture, and LifeScan will market, additional electrochemical blood glucose
monitoring systems.

                                       3
<PAGE>
    Inverness' objective is to be the leading provider of innovative products
that provide a fully integrated and comprehensive approach to the
self-management of diabetes. The key elements of Inverness' strategy for
achieving this goal are to:

    - continue to develop superior blood glucose monitoring products;

    - maximize market penetration of its products through strategic partnerships
      and through its wholesale and retail distribution networks;

    - develop or acquire a comprehensive and integrated array of products for
      diabetes self-management; and

    - continue to manufacture high quality products in mass volumes at low
      costs.

    Consistent with its objectives, Inverness continues to focus on the
development of pain-free, non-disruptive, continuous blood glucose monitoring
systems and other complementary diabetes self-management products. For example,
in addition to this merger with Integ, which Inverness believes will supplement
and accelerate its existing efforts to develop glucose monitoring systems that
do not require blood samples, more recently, Inverness entered into a
development and license agreement with Debiotech, S.A. pursuant to which
Debiotech will seek to develop an externally worn insulin pump using its
proprietary technology.

    Inverness was incorporated in August 25, 1992 in Delaware under the name
Selfcare, Inc. Inverness changed its name to Inverness Medical Technology, Inc.
in May 2000.

RECENT DEVELOPMENTS OF INVERNESS

DEVELOPMENT AND LICENSE AGREEMENT WITH DEBIOTECH, S.A.

    On October 14, 2000, Inverness entered into a development and license
agreement with Debiotech, S.A., pursuant to which Debiotech will seek to develop
an externally-worn insulin pump using its proprietary technology in exchange for
a $10 million fee. Inverness also received an option, exercisable in certain
circumstances for an additional fee, for the exclusive right to commercialize an
implantable insulin pump which Debiotech may seek to develop using its
proprietary technology.

OFFERING FOR ADDITIONAL INVERNESS COMMON STOCK


    On October 24, 2000, Inverness filed a registration statement on Form S-3
with the SEC with respect to the registration and sale of 3,350,000 shares of
Inverness common stock by Inverness and an additional 250,000 shares of common
stock by certain selling stockholders, which was consummated on November 27,
2000, at $25.00 per share (less underwriting discounts and commissions). The
underwriters in this offering were also granted an option to purchase 150,000
shares of Inverness common stock from Inverness and 390,000 shares of Inverness
common stock from the selling stockholders solely to cover overallotments, which
was exercised on November 24, 2000 and consummated in full on November 28, 2000
at $25.00 per share (less underwriting discounts and commissions). Accordingly,
after the closing of the offering and the overallotment option on November 28,
2000, there were 29,100,106 shares of Inverness common stock outstanding, not
including the shares to be issued pursuant to the merger. Inverness intends for
the proceeds of the offering to be used for the repayment of certain
indebtedness, to fund a portion of the consideration payable in the acquisition
of Integ, to pay a fee due under its licensing agreement with Debiotech, to fund
the redemption of preferred stock of a subsidiary and for working capital and
other general corporate purposes, including other possible acquisitions.

INTEG (SEE PAGE 60)

    The principal executive office of Integ, a Minnesota corporation, is located
at 2800 Patton Road, St. Paul, Minnesota 55113, and its telephone number is
(651) 639-8816.

    Integ Incorporated is a development stage medical technology company focused
on developing an innovative glucose monitoring product to enable people with
diabetes to manage this disease more effectively and conveniently. Integ has
focused its efforts on developing methods to sample interstitial fluid, the
clear fluid found between the cells throughout the body, and methods of
presenting this sample to various types of glucose measurement systems in an
integrated fashion. Integ has developed and patented what it believes is a
unique technology to collect interstitial fluid samples. Using this technology,
it has conducted extensive research on interstitial fluid. With Integ's
advancements in interstitial fluid sampling technology and knowledge of
interstitial fluid, it hopes to improve diabetes self-management by eliminating
the need to draw blood for glucose monitoring. Integ believes that its
technology, when combined with commercially available glucose measurement
technology, will create a handheld glucose monitoring product for use by people
with diabetes that will be simpler to use and less messy than current alternate
site blood based test systems, and less painful than traditional fingerstick
devices. Integ believes that this product, which Integ refers to as the
LIFEGuide-TM- System, will allow people with diabetes to frequently self-monitor
their glucose levels without repeatedly enduring the pain and mess associated
with lancing their fingers to obtain a blood sample. Integ is a development
stage company and was incorporated in April 1990 in Minnesota.

                              THE SPECIAL MEETING

DATE AND PURPOSE (SEE PAGE 25)


    A special meeting of Integ shareholders will be held at the Minneapolis
Marriott City Center, 30 South 7th Street, Minneapolis, Minnesota 55402 on
January 23, 2001 at 10:00 a.m., local time.


RECORD DATE; VOTING RIGHTS (SEE PAGE 25)


    If you owned shares of Integ common stock as of the close of business on
December 13, 2000, the record date for the special meeting, you may vote on the
approval of the merger agreement.



    On that date, there were 9,922,285 shares of Integ common stock outstanding.
Integ shareholders will have one vote at the meeting for each share of common
stock they owned on the record date.


REQUIRED VOTES (SEE PAGE 25)

    To approve the merger, holders of a majority of the outstanding shares of
Integ common stock must vote to approve the merger agreement. If you fail to
vote or abstain from voting, it will have the effect of a vote against the
merger. A broker who holds Integ stock as your nominee will not have authority
to vote your shares unless you provide the broker with specific voting
instructions.


    On the record date, directors and officers of Inverness as a group owned no
shares of Integ stock, and directors and officers of Integ as a group owned
approximately 5% of the outstanding shares of Integ stock. In addition, certain
Integ shareholders, some of whom are directors and officers of Integ, who
beneficially own approximately 15.4% of the outstanding shares of Integ common
stock, entered into an agreement with Inverness to vote their shares in favor of
the merger. These Integ shareholders were not paid additional consideration to
enter into the voting agreement. For further information, please refer to "The
Merger Agreement--Related Agreements--Voting Agreement" on page 58 of this proxy
statement and prospectus.

                                   THE MERGER

SUMMARY OF THE TRANSACTION

    Inverness and Integ executed a merger agreement on October 3, 2000, which
was amended on October 16, 2000. The merger agreement provides for a merger of
Integ with and into Terrier Acquisition Corp., a newly formed, wholly owned
subsidiary of Inverness. The surviving company will be Terrier, which will
remain a wholly owned subsidiary of Inverness.

    The proposed merger will occur following approval of the merger agreement by
the Integ shareholders and satisfaction or waiver of all other conditions to the
merger. The merger agreement, as amended, is attached as Annex A. We encourage
you to read it because it is the legal document that governs the merger.

WHAT THE HOLDERS OF INTEG COMMON STOCK WILL RECEIVE IN THE MERGER (SEE PAGE 45)

    In the merger, each outstanding share of Integ common stock will be
converted into the right to receive a fixed number of shares of common stock of
Inverness based on an exchange ratio calculated as follows:

<TABLE>
<S>               <C>                                                          <C>
                                                                                  aggregate exercise
                                                                                 price of Integ stock
                       (average closing price of Inverness common stock X        options and warrants
                                         1,900,000) +                            options and warrants
                    ---------------------------------------------------------------------------------
exchange ratio =                     average closing price of Inverness common stock
                  -------------------------------------------------------------------------------------
                        total number of shares of Integ common stock outstanding immediately prior
                     to the effective time of the merger + the total number of shares of Integ common
                             stock issuable upon exercise of Integ stock options and warrants
</TABLE>

    For the purpose of calculating the exchange ratio, the average closing price
for Inverness common stock will be computed by averaging the closing sale prices
of Inverness common stock on the American Stock Exchange for the five trading
days immediately preceding the effective time of the merger.


    Since some of the variables necessary to determine the exchange ratio will
not be determined until immediately prior to the effective time of the merger,
the precise exchange ratio will not be determined until immediately prior to the
effective time of the merger. However, if the effective time of the merger were
December 13, 2000, the record date, the exchange ratio would equal approximately
 .1734.


    No fractional shares of Inverness common stock will be issued in connection
with the merger. Instead, you will receive an amount of cash for any fractional
shares that would otherwise be issued.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES (SEE PAGE 76)

    We intend that the merger qualify as a reorganization within the meaning of
section 368(a) of the Internal Revenue Code. If the merger does qualify as a
reorganization, no gain or loss will be recognized by Integ, Inverness or
Terrier by reason of the merger. In addition, you will not recognize gain or
loss on the exchange of your shares of Integ stock for shares of Inverness
stock, except for any cash you receive instead of fractional shares. BECAUSE THE
TAX CONSEQUENCES OF THE MERGER MAY VARY DEPENDING UPON EACH INTEG SHAREHOLDER'S
PARTICULAR CIRCUMSTANCES, WE URGE YOU TO CONSULT YOUR OWN TAX ADVISORS ABOUT THE
FEDERAL, STATE, LOCAL OR FOREIGN TAX CONSEQUENCES TO YOU AS A RESULT OF THE
MERGER.

DISSENTERS' APPRAISAL RIGHTS (SEE PAGE 41)

    Integ's shareholders may exercise dissenters' appraisal rights in connection
with the merger. Any shareholder exercising dissenter's appraisal rights will be
required to follow the procedures set forth

                                       6
<PAGE>
under Minnesota law and will receive cash for the shareholder's Integ common
stock. If a shareholder fails to follow the proposed procedure for exercising
dissenters' appraisal rights, these rights may be terminated or waived.

INTERESTS OF INTEG DIRECTORS AND OFFICERS IN THE MERGER (SEE PAGE 39)

    Some of Integ's executive officers and directors have interests in the
merger that are different from, or in addition to, those of Integ shareholders
generally. For instance, all outstanding options to purchase Integ stock will
vest and become exercisable immediately prior to the closing of the merger.
Integ intends to compensate employees for any excise tax required by
section 280G of the Internal Revenue Code resulting from the acceleration of
vesting of these stock options. In addition, the executive officers of Integ
have employment agreements that provide for certain benefits if the officer is
terminated by Inverness without cause or if he or she terminates his or her
employment for good reason following a change of control. Furthermore, the
merger agreement provides officers and directors of Integ with continuing
indemnification rights.

CONDITIONS TO THE MERGER (SEE PAGE 54)

    Inverness and Integ will not complete the merger unless a number of
conditions are satisfied or waived, including approval of the merger agreement
by the Integ shareholders.

LIMITATION ON CONSIDERING OTHER ACQUISITION PROPOSALS (SEE PAGE 52)

    Integ has agreed not to consider an acquisition proposal, such as a business
combination or other similar transaction, with a party other than Inverness
while the merger is pending unless the other party has made an unsolicited
written proposal that represents a superior proposal. The determination as to
whether an acquisition proposal is a superior proposal would be based on the
financial benefit to Integ shareholders. In addition, to consider a superior
proposal, the board of Integ must also be satisfied with the other party's
ability to finance the transaction and that considering the superior proposal is
required by the directors' fiduciary duties.

TERMINATION OF THE MERGER AGREEMENT (SEE PAGE 56)

    The merger agreement may be terminated by mutual written consent. Either
Inverness and Terrier, on the one hand, or Integ, on the other hand, may
terminate the merger agreement if:

    - Integ shareholder approval is not obtained at the special meeting;

    - any governmental entity has issued an injunction or taken other action
      that permanently enjoins the merger;

    - the other party materially breaches any representation, warranty, covenant
      or agreement contained in the merger agreement (except for those breaches
      unlikely to have a material adverse effect on the business, results of
      operations or financial condition of the breaching party); or

    - the merger has not occurred by March 31, 2001, without a material breach
      by the terminating party of its obligations under the merger agreement.

    The merger agreement may be terminated by Integ prior to the special meeting
if Integ concurrently enters into a definitive agreement with respect to a
superior proposal, provided that Integ:

    - provides Inverness and Terrier with five business days prior notice of the
      decision to terminate during which time Inverness may propose any
      adjustment to the merger agreement; and

    - pays to Inverness or its designee a $2.0 million termination fee
      concurrently with the effectiveness of the termination.

                                       7
<PAGE>
    The merger agreement may be terminated by Inverness or Terrier if:

    - the Integ board does not make a recommendation of, or withdraws, amends,
      modifies or changes its approval or recommendation of, the merger
      agreement or the transactions contemplated thereby;

    - the Integ board fails to include its favorable recommendation regarding
      the merger in this proxy statement and prospectus;

    - the Integ board recommends any superior proposal;

    - the Integ board publicly expresses no opinion and remains neutral in
      respect of any acquisition proposal or the merger and related
      transactions;

    - Integ enters into a definitive agreement with respect to a superior
      proposal; or

    - Integ makes any proposal or announces its intention to enter into an
      agreement with respect to an acquisition proposal with a party other than
      Inverness.

TERMINATION FEES AND EXPENSES (SEE PAGE 57)

    The merger agreement requires Integ to pay Inverness a termination fee of
$2.0 million in cash if:

    - Integ terminates the merger agreement in order to effect a superior
      proposal; or

    - Inverness or Terrier terminates the merger agreement as a result of:

       - the Integ board failing to make a recommendation of, or having
         withdrawn, amended, modified or changed its approval or recommendation
         of, the merger agreement;

       - the Integ board failing to include its favorable recommendation
         regarding the merger in this proxy statement and prospectus;

       - the Integ board recommending any superior proposal;

       - the Integ board publicly expressing no opinion and remaining neutral in
         respect of any acquisition proposal or the merger and related
         transactions;

       - entering into a definitive agreement with respect to a superior
         proposal;

       - Integ making a proposal or announcement of its intention to enter into
         an agreement with respect to an acquisition proposal; or

       - Integ or its board resolving to do any of the actions discussed in the
         five points above.

    Furthermore, if either party terminates the merger agreement because:

    - the required approval of the Integ shareholders has not been obtained at
      the special meeting;

    - the merger has not occurred by March 31, 2001 (and the terminating party
      is not in material breach of its obligations); or

    - Inverness or Terrier terminates the merger agreement because Integ
      materially breaches any representation, warranty, covenant or agreement
      contained in the merger agreement;

    AND if prior to one year from such termination, Integ enters into an
acquisition proposal with any other entities (with certain exceptions) or the
Integ board recommends or resolves to recommend to Integ shareholders approval
or acceptance of an acquisition proposal with any party (with certain
exceptions);

    THEN Integ is required to pay Inverness a fee of $2.0 million.

    Additionally, if Inverness or Terrier terminates the merger agreement
because Integ materially breaches any representation, warranty, covenant or
agreement contained in the merger agreement, and this breach is caused by a
willful act, omission or other willful misconduct of Integ, then Integ is
required to reimburse Inverness and Terrier for their out-of-pocket costs and
expenses incurred in

                                       8
<PAGE>
connection with the merger agreement and the transactions contemplated thereby,
up to a maximum of $2.0 million.

FAIRNESS OPINION OF U.S. BANCORP PIPER JAFFRAY INC. (SEE PAGE 34)

    In deciding to approve the merger, the Integ board considered an opinion
from its financial advisor, U.S. Bancorp Piper Jaffray Inc. On October 3, 2000,
U.S. Bancorp Piper Jaffray delivered its written opinion to the Integ board of
directors that as of that date and based on and subject to the matters set forth
in the opinion, the consideration to be received by holders of common stock
pursuant to the merger agreement was fair, from a financial point of view, to
Integ common shareholders. The full text of this written opinion is attached as
Annex B to this proxy statement and prospectus. We encourage you to read this
opinion carefully in its entirety. The opinion of U.S. Bancorp Piper Jaffray is
directed to the Integ board and is not a recommendation to any shareholder on
how to vote on the merger or the merger agreement.

TREATMENT OF STOCK OPTIONS AND WARRANTS (SEE PAGE 39)

    Each option and warrant to purchase shares of Integ stock outstanding
immediately prior to the merger will be assumed by Inverness and will become an
option or warrant, as the case may be, to acquire Inverness stock. Inverness
will adjust the number of shares issuable upon exercise and the exercise prices
to reflect the merger's exchange ratio.

ACCOUNTING TREATMENT (SEE PAGE 41)

    Inverness expects to account for the merger as an asset acquisition, which
means the assets and liabilities of Integ, including its intangible assets, will
be recorded on Inverness' books at their fair values. The results of operations
and cash flows of Integ will be included in Inverness' financial statements
prospectively as of the closing of the merger. It is expected that a substantial
portion of the purchase price will be allocated to Integ's in-process research
and development, which, under generally accepted accounting principles, will be
expensed by Inverness immediately following completion of the merger.

REGULATORY APPROVALS

    We are not aware of any material governmental or regulatory approvals
required for closing the merger other than compliance with federal securities
laws.

PURCHASE OF SERIES B PREFERRED STOCK (SEE PAGE 40)


    The merger agreement requires that Inverness fund the redemption for cash of
all of Integ's outstanding shares of Series B preferred stock at a price equal
to the amount of funds that Integ received from Amira Medical in exchange for
such Series B preferred stock plus a 10% premium. As of the date of this proxy
statement and prospectus, there are 1,983,123 shares of Series B preferred stock
outstanding and the redemption price would be $4,977,266.87.


COMPARATIVE STOCKHOLDER RIGHTS (SEE PAGE 97)

    When we complete the merger, Integ shareholders will hold shares of
Inverness common stock. Your rights as an Inverness stockholder will be governed
by Inverness' certificate of incorporation and bylaws and by Delaware general
corporate laws. Integ shareholders will have different rights as holders of
Inverness common stock than they currently have as holders of Integ common
stock.

 INTEG'S REASONS FOR THE MERGER AND RECOMMENDATION OF INTEG BOARD (SEE PAGE 32)

    Integ's board of directors consulted with senior management and Integ's
financial and legal advisors and considered a number of factors, including those
set forth below, in reaching its decision to approve the merger agreement and
the transactions contemplated by the merger agreement, and to recommend that
Integ's shareholders vote "FOR" approval of the merger agreement.

    - Integ's development of technology in connection with its alliance with
      Amira Medical and the progress of potential competitors;

    - the relative value of the consideration to be received by Integ
      shareholders compared to the historical and recent market prices of Integ
      common stock;

    - the potential consideration to be received in, and likelihood of, Integ
      exercising its option to merge with a subsidiary of Amira;

    - the fairness opinion of Integ's financial advisor, U.S. Bancorp Piper
      Jaffray;

    - Integ's prospects of remaining independent;

    - the possible effect of the merger on the current facility and employees;

    - the ability of Integ to terminate the merger agreement in the event of a
      superior proposal, subject to the payment of a termination fee; and

    - the limited nature of the closing conditions included in the merger
      agreement.

    The foregoing discussion of the information and factors considered by
Integ's board of directors, while not exhaustive, includes the material factors
considered by the board of directors. In view of the variety of factors
considered in connection with its evaluation of the merger, Integ's board of
directors did not find it practicable to, and did not, quantify or otherwise
assign relative or specific weight or values to any of these factors, and
individual directors may have given different weights to different factors.

                INVERNESS' REASONS FOR THE MERGER (SEE PAGE 31)

    In reaching its decision to approve the merger, the Inverness board
considered, among other things, the following factors:

    - acquiring the technology contained within Integ's LIFEGuide-TM- System of
      glucose measurement on Inverness' revenue and earnings;

    - the rights of Amira Medical in certain of Integ's intellectual property,
      including certain exclusive rights with respect to jointly developed
      technology;

    - the development and potential commercialization of Integ's proprietary
      interstitial fluid sampling technology; and

    - synergies resulting from the acquisition of Integ's existing and
      in-process intellectual property and the elimination of redundancies.

                           COMPARATIVE PER SHARE DATA

    We are providing the following comparative per share information to aid you
in your analysis of the financial aspects of the merger. You should read this
information in conjunction with each company's historical financial statements
and unaudited pro forma condensed consolidated financial statements and the
related notes that are included elsewhere in this proxy statement and
prospectus. The unaudited pro forma consolidated per share data presented below
reflects the purchase method of accounting for business combinations. The
results may have been different if the companies had always been consolidated.


    Both Inverness and Integ have fiscal years ending on December 31. The Integ
pro forma equivalent per share data equals an assumed exchange ratio of .1734
multiplied by the Inverness pro forma consolidated per share data. The actual
exchange ratio will not necessarily equal this assumed exchange ratio, and the
pro forma per share data are not necessarily indicative of the results that
would have occurred if the merger had been completed on the dates indicated or
the results that will occur after the merger. Please refer to the section of

DIVIDEND INFORMATION

    No cash dividends have ever been paid or declared on the shares of Inverness
common stock or Integ common stock. Inverness does not intend to pay cash
dividends on its common stock in the foreseeable future. Inverness' present
intention is to retain its earnings to finance the growth and development of its
business. Any future payment of dividends on Inverness stock will be at the
board's discretion and will depend upon, among other things, Inverness'
earnings, financial condition, capital requirements, level of indebtedness and
other factors that the Inverness board deems relevant.

                                  RISK FACTORS

    In addition to the other information included in this proxy statement and
prospectus, you should consider carefully the risk factors described below in
deciding how to vote on the merger proposal. You should keep these risk factors
in mind when you read forward-looking statements. Please refer to the section of
this proxy statement and prospectus entitled "Special Note Regarding
Forward-looking Statements."

                          RISKS RELATING TO THE MERGER

THE EXCHANGE RATIO FOR INTEG STOCK IN THE MERGER IS FIXED AGAINST A SET NUMBER
OF SHARES OF INVERNESS STOCK AND WILL NOT BE ADJUSTED IF THERE IS ANY CHANGE IN
THE PRICE OF INVERNESS STOCK.

    In the merger, Integ stock will be exchanged for Inverness stock at an
exchange ratio designed to provide that a total of 1,900,000 shares of Inverness
common stock, net of exercise amounts attributable to the options and warrants,
will be issued to:

    - existing holders of shares of Integ common stock;

    - holders of options to purchase shares of Integ common stock; and

    - holders of warrants to purchase Integ common stock.


For more information on the determination of the exchange ratio, see the section
of this proxy statement and prospectus entitled "The Merger Agreement--Merger
Consideration" on page 45. The market value of Inverness stock on and after the
closing date of the merger may vary significantly from the prices on the date of
execution of the merger agreement, the date of this proxy statement and
prospectus and the date on which you vote on the merger. Any change in the price
of Inverness stock will affect the value of the consideration that Integ
shareholders receive in the merger. The price of Inverness stock can be volatile
and the price at the time that the merger is completed may be lower than its
price on the date of this document or the date of the Integ special meeting. On
October 3, 2000, the date of the execution of the merger, the closing price of
Inverness stock was $18.875 per share. On December 13, 2000, the record date,
the closing price of Inverness stock was $36.6875 per share. You are encouraged
to obtain current market quotations for Inverness stock.


INVERNESS FACES DIFFERENT MARKET RISKS FROM THOSE FACED BY INTEG, AND THESE
RISKS MAY CAUSE THE VALUE OF THE SHARES OF INVERNESS STOCK ISSUED TO YOU TO
DECLINE.


    In the merger you will receive shares of Inverness stock. Inverness stock
has historically experienced significant fluctuations in price and volume. The
business, strategy and financial condition of Inverness are somewhat different
from that of Integ. Inverness' results of operations, as well as the price of
Inverness stock, will be affected by various factors different from those
affecting Integ's results of operations and its common stock price. Future
events that may not have affected the price of Integ stock may cause the price
of Inverness stock to fall.



    For a description of and other information about Inverness stock and
differences between Inverness stock and Integ stock, see the sections of this
proxy statement and prospectus entitled "Comparative Per Share Data" on
page 15, "Comparative Stock Prices and Dividends" on page 16 and "Comparison of
Rights of Shareholders of Integ and Stockholders of Inverness" on page 97.


THE MERGER MAY NOT YIELD PRODUCTS OR TECHNOLOGY THAT CAN BE COMMERCIALIZED BY
INVERNESS.


    The value of Integ to Inverness may not be greater than or equal to the
purchase price which Inverness has agreed to pay. If Inverness is unable to
effectively integrate the technologies of Integ into the research and
development efforts of Inverness, its research and development efforts may
suffer. Further, Inverness cannot guarantee that it will realize any of the
benefits or strategic objectives it is


                                       17
<PAGE>

seeking to obtain by acquiring Integ. In that regard, Integ has granted to a
third party certain rights in its intellectual property that survive the
acquisition by Inverness which will permit this third party to also utilize
substantially all the technology that Inverness will acquire. In connection with
accounting for the acquisition of Integ, Inverness will record a significant
amount of intangible assets, the amortization of which will adversely affect its
results of operations in future periods. In addition, Inverness will also record
a significant charge for the write-off of a portion of the purchase price as
in-process research and development. For the purpose of preparing the pro forma
information that is included in summary form in this proxy statement and
prospectus, Inverness estimated the allocation of the purchase price. The final
purchase price allocation will be based, in part, on an independent appraisal of
the acquired intangible assets and the charge for in-process research and
development. The appraisal results and final allocation of the purchase price
could vary significantly from Inverness' original estimates, which would result
in a greater or lesser non-recurring charge for the write-off of a portion of
the purchase price as in-process research and development during the quarter in
which the merger is consummated.


THE TERMINATION FEE AND THE RESTRICTIONS ON SOLICITATION CONTAINED IN THE MERGER
AGREEMENT MAY DISCOURAGE OTHER COMPANIES FROM TRYING TO ACQUIRE INTEG.

    Until the completion of the merger, and with some exceptions, Integ is
prohibited from entering into or soliciting, initiating or encouraging any
inquiries or proposals that may lead to a proposal or offer for a merger or
other business combination transaction with any person other than Inverness. In
addition, Integ agreed to pay a termination fee to Inverness in specified
circumstances, including where a third party acquires or seeks to acquire Integ.
These provisions could discourage other companies from trying to acquire Integ
even though those other companies might be willing to offer greater value to
Integ shareholders than Inverness has offered in the merger. The payment of the
termination fee could also have a material adverse effect on Integ's financial
condition.

OFFICERS AND DIRECTORS OF INTEG HAVE INTERESTS THAT ARE DIFFERENT FROM, OR IN
ADDITION TO, INTERESTS OF INTEG'S SHAREHOLDERS GENERALLY.

    The officers and directors of Integ have interests in the merger that are in
addition to, or different from, their interests as Integ shareholders. The Integ
board was aware of these conflicts of interest when it approved the merger.
These interests include:

    - the accelerated vesting of stock options upon consummation of the merger
      and the ability of certain officers of Integ to receive compensation for
      any excise taxes payable by virtue of such acceleration;


    - the receipt of severance benefits under employee retention agreements in
      the event any of Integ's officers are terminated by Inverness after the
      merger; and


    - the receipt of indemnification and insurance coverage with respect to acts
      and omissions in their capacities as officers and directors of Integ.

    For a more detailed discussion of these interests, see the section of this
proxy statement and prospectus entitled "The Merger--Interests of Integ's
Directors and Officers in the Merger" on page 39.

SUBSTANTIALLY ALL OF THE INTELLECTUAL PROPERTY OF INTEG IS ALSO LICENSED TO, AND
SUBLICENSABLE BY, ANOTHER COMPANY.


    The consummation of the merger will trigger certain significant provisions
contained in Integ's development and license agreement with Amira Medical.
Primary among these consequences is that Amira will be granted an exclusive,
perpetual, non-terminable and transferable license to all Integ


                                       18
<PAGE>

intellectual property relating to glucose monitoring using interstitial fluid
developed after April 2, 1999 and through the date of the closing of the merger,
and a co-exclusive, perpetual, non-terminable and transferable license to all
Integ intellectual property relating to glucose monitoring using interstitial
fluid, other than its infrared technology, in existence as of April 2, 1999.
Accordingly, after the closing of the merger, Inverness will receive no rights
to any Integ intellectual property relating to glucose monitoring using
interstitial fluid developed after April 2, 1999. In addition, with respect to
all Integ intellectual property relating to glucose monitoring using
interstitial fluid developed up to and through April 2, 1999, including all
patents owned and patent applications pending, Inverness, as the successor to
Integ, will receive a co-exclusive license with Amira. Integ and Inverness do
not expect that the co-exclusive license will affect Inverness' plans to use
Integ's intellectual property in the future because Inverness intends to utilize
only the intellectual property that was in existence or pending as of April 2,
1999, which includes the patents relating to the LIFEGuide-TM- System and
Integ's proprietary interstitial fluid sampling. However, Amira will also
possess the rights to utilize this technology and the exclusive rights to all
post-April 2, 1999 technology, which Amira will be able to develop and
commercialize. Furthermore, Amira is not prohibited from transferring its
license to use such technology to any other person, including to competitors of
Inverness. Accordingly, there is nothing to prevent the intellectual property
that Inverness is acquiring in the merger from also being owned and possibly
commercialized by Inverness' competitors.


                          RISKS RELATING TO INVERNESS


    In the merger, Inverness will issue shares of Inverness stock in exchange
for Integ stock. Accordingly, before voting on the merger, you should carefully
consider the factors relating to Inverness and the operation of its business
generally that are included in Inverness' filings with the Securities and
Exchange Commission from time to time that have been or are thereafter
incorporated by reference into this document, including the risk factors set
forth under the heading "Management's Discussion and Analysis of Financial
Conditions and Results of Operations--Certain Factors Affecting Future Results."
YOU ARE URGED TO READ THESE RISK FACTORS CAREFULLY. These risks could result in
material adverse consequences to Inverness' business, financial condition,
operating results or cash flows. These consequences could cause the trading
price of Inverness stock to decline.


                            RISKS RELATING TO INTEG

    The following matters, among others, may have a material adverse effect on
the business, financial condition, liquidity, results of operations or
prospects, financial or otherwise, of Integ, particularly if the shareholders of
Integ do not vote to approve the merger agreement at the special meeting.

INTEG IS DEVELOPING A NEW TECHNOLOGY WHICH MAY NEVER BECOME COMMERCIALLY VIABLE
OR IF VIABLE MAY NEVER ACHIEVE MARKET ACCEPTANCE.

    Integ is a development stage company and does not have any commercial
products available for sale. Integ is developing an interstitial fluid sampling
technology. This technology, when combined with a measurement technology, will
create a handheld glucose monitoring product, referred to as the LIFEGuide-TM-
System, for use by people with diabetes that avoids the pain and blood
associated with conventional "finger-stick" technologies. Integ's future success
is dependent upon the successful development of the LIFEGuide-TM- System, which
is ongoing and the complete efficacy of which has not yet been demonstrated.
Integ does not own rights to a glucose measurement technology to use with the
LIFEGuide-TM- System. In order to successfully develop the LIFEGuide-TM- System,
Integ must obtain rights to a proven glucose measurement technology, such as
that used by Inverness. Unforeseen problems may occur in any or all of the
following areas:

    - research and development;

                                       19
<PAGE>
    - integration of Integ's sampling technology with Inverness' measuring
      technology;

    - clinical testing;

    - regulatory submissions and clearance or approval;

    - product manufacturing and commercial scale up;

    - marketing; or

    - product distribution.

    Occurrence of any of these problems could materially delay the
commercialization of the LIFEGuide-TM- System or prevent its market introduction
entirely. Further, even if successfully developed, the commercial success of the
LIFEGuide-TM- System will depend upon its acceptance as an accurate, reliable
and cost-effective alternative to existing blood glucose monitoring techniques.
The glucose monitoring industry is currently dominated by several companies with
established markets and distribution channels. Because the proposed
LIFEGuide-TM- System will represent a new practice in the monitoring of glucose
levels, Integ is unable to predict how quickly, if at all, its products will be
accepted by members of the medical community and people with diabetes.

INTEG IS CURRENTLY DEPENDENT ON EXTERNAL SOURCES OF FUNDING TO MEET ITS
OPERATIONAL EXPENSES, HAS A HISTORY OF OPERATING LOSSES AND EXPECTS LOSSES TO
CONTINUE.

    Integ has generated no revenue and has sustained significant operating
losses each year since its inception. As of September 30, 2000, Integ had an
accumulated deficit of $53,522,000. Integ incurred net losses of $7,844,000 for
the year ended December 31, 1999, $11,086,000 for the year ended December 31,
1998 and $11,564,000 for the year ended December 31, 1997, and Integ expects
such losses to continue through 2000. To increase its available cash, in
February 2000, Integ announced that Amira agreed to provide funding of up to
$5,600,000 through purchases of Series B preferred stock for continued
LIFEGuide-TM- System development during the year 2000. As an independent
company, Integ would remain dependent upon sales of Series B preferred stock to
Amira to meet its operating expenses, and will remain so dependent unless the
merger occurs. Furthermore, pursuant to its existing arrangement with Amira,
Integ will receive only a fixed percentage of profit over its costs up to a
certain cap in producing the LIFEGuide-TM- Key, which is not based upon the
price that the LIFEGuide-TM- System may sell.


    Pursuant to the terms of the Series B purchase agreement, Integ will be
required to redeem for either cash or Integ common stock all outstanding shares
of Series B preferred stock at a 10% premium upon the closing of the merger with
Inverness. Integ has elected to redeem the Series B preferred stock for cash. It
is anticipated that the cost to Integ for this redemption will be $4,977,266.87,
and Inverness has agreed to fund this amount.


    If the merger is not completed, adequate funds for Integ's operations,
whether from third parties, financial markets or from other sources, may not be
available when needed on terms attractive to Integ or at all. Insufficient funds
may prevent the commercial introduction of the LIFEGuide-TM- System altogether.

APPROVAL OF THE LIFEGUIDE-TM- SYSTEM IS SUBJECT TO A RIGOROUS PROCESS FOR FDA
CLEARANCE OR APPROVAL.

    Testing of the current LIFEGuide-TM- System has been performed on prototypes
solely by Integ and Amira personnel under controlled circumstances. The FDA has
informed Integ that a premarket approval application (PMA) is the most likely
submission which will be required to permit commercialization of the
LIFEGuide-TM- System in the United States. Neither Integ nor Inverness can
predict whether problems will be encountered in clinical testing which will
cause delays in the commercialization of the LIFEGuide-TM- System. Neither Integ
nor Inverness can predict whether the

                                       20
<PAGE>
LIFEGuide-TM- System will prove to be accurate and reliable on a consistent
basis or that the LIFEGuide-TM- System will be safe or effective. Neither Integ
nor Inverness can also not predict whether the required FDA clearances will be
obtained on a timely basis or at all.

THE GLUCOSE MONITORING INDUSTRY IS HIGHLY COMPETITIVE AND MOST PARTICIPANTS ARE
LARGER THAN INTEG AND HAVE BETTER CAPITALIZATION AND ARE MORE EXPERIENCED THAN
INTEG.

    The glucose monitoring industry is characterized by continuously evolving
technology and intense competition, and the market is currently dominated by
several companies with established products and distribution channels. In
addition, other companies are attempting to develop minimally or noninvasive
glucose monitoring products competitive with the proposed LIFEGuide-TM- System.
If the merger is not completed and Integ remains an independent company, it is
possible that Integ's competitors and potential competitors may succeed in
developing or marketing technologies and products that will be more accepted in
the marketplace than the proposed LIFEGuide-TM- System or that would render
Integ's technology and proposed device obsolete or noncompetitive. In addition,
numerous researchers are investigating alternative treatments or cures for
diabetes. If any of these efforts are successful in reducing the complications
associated with diabetes and can be cost-effectively provided to people with
diabetes, the need for Integ's products could be mitigated or become entirely
nonexistent.


    Furthermore, most of Integ's competitors and potential competitors have
substantially greater capital resources, research and development staffs and
facilities than Integ currently and Integ as anticipated if the merger does not
occur and Integ remains an independent company. In addition, most of Integ's
competitors and potential competitors have substantially greater experience than
Integ in research and new product development, obtaining regulatory approvals
and manufacturing and marketing medical devices. Many of Integ's potential
competitors have already entered into distribution and marketing agreements with
major marketing partners.


INTEG'S LIFEGUIDE-TM- SYSTEM REQUIRES MANUFACTURING CAPABILITIES GREATER THAN
CURRENTLY IN PLACE AND ALSO DEPENDS ON TIMELY AND RELIABLE DELIVERY FROM
SUPPLIERS.

    Integ's LIFEGuide-TM- System is still in development. To be successful,
LIFEGuide-TM- System must be manufactured in compliance with regulatory
requirements, in a timely manner and in sufficient quantities while maintaining
product quality and acceptable manufacturing costs. If the merger with Inverness
is not consummated, Integ plans to assemble the disposable key portion of the
LIFEGuide-TM- System from components to be purchased from outside suppliers.
Manufacturers often encounter difficulties in scaling up production of new
products, including problems involving production yields, quality control and
assurance, component supplies and shortages of personnel. Accordingly, in that
case, Integ may not be able to achieve and maintain product quality and
reliability when producing the LIFEGuide-TM- System in the quantities required
for commercial operations or within a period that will permit Integ to introduce
its product in a timely fashion, nor may Integ be able to assemble and
manufacture its product at an acceptable cost.

INTEG DEPENDS GREATLY ON OBTAINING PATENTS AND OTHER METHODS OF SAFEGUARDING AND
PROTECTING ITS INTELLECTUAL PROPERTY AND PROPRIETARY TECHNOLOGY. FAILING TO
ADEQUATELY PROTECT THESE INTERESTS, OR PROTECTING OR DEFENDING INTERESTS THROUGH
LITIGATION, MAY BE COSTLY TO INTEG.

    Integ's success as an independent company if the merger with Inverness is
not completed will depend in part on its ability to obtain patent protection for
its proposed products and processes, to preserve its trade secrets and to
operate without infringing the proprietary rights of third parties. Under the
terms of the development and license agreement with Amira, upon the closing of
the merger with Inverness, Integ will be deemed to have granted to Amira an
exclusive license to all of Integ's technology relating to glucose monitoring
using interstitial fluid developed after the date of the agreement and a
coexclusive license to Integ's technology relating to glucose monitoring
interstitial

                                       21
<PAGE>
fluid developed prior to the date of the agreement. Integ has historically
pursued a policy of seeking patent protection for each of the areas of invention
embodied in the LIFEGuide-TM- System. Integ has four issued United States
patents relating to the method of drawing a body fluid sample from the outer
layers of the skin, as well as six related United States patents. Integ has
several pending United States patent applications directed toward various
aspects of the technologies underlying the LIFEGuide-TM- System. Integ has also
filed two corresponding foreign patent applications related to its sampling
methods, in order to seek similar patent protection outside the United States.
The first of these has received a favorable option and has been filed in Europe
and three non-European countries. The European application has been granted and
is being filed in selected member states. Integ cannot be sure, however, that

    - any additional patents will be issued;

    - the scope of any patent protection granted to Integ will prevent
      competitors from introducing products competitive with the LIFEGuide-TM-
      System; or

    - any of Integ's patents will be held valid or enforceable if subsequently
      challenged.

    Patenting medical devices involves complex legal and factual questions, and
there is no consistent policy regarding the breadth of claims that pertain to
such technologies. Integ also has relied, and currently relies, upon unpatented
trade secrets. Neither Integ nor Inverness can be sure others will not
independently develop or otherwise acquire unpatented technologies substantially
equivalent to those of Integ currently. In addition, even if the patents for
which Integ has applied are ultimately issued, other parties may hold or receive
patents that contain claims covering the LIFEGuide-TM- System and which may
delay or prevent the sale of the LIFEGuide-TM- System or require licenses
resulting in the payment of fees or royalties by Integ in order for Integ to
carry on its business. In addition, needed or potentially useful licenses may
not be available to Integ in the future on acceptable terms or at all.

    There has been substantial litigation regarding patent and other
intellectual property rights in the medical device industry. As an independent
company, litigation could result in substantial costs to and a diversion of
effort by Integ. However, litigation may be necessary to enforce any patents
issued to Integ, protect trade secrets or know-how owned by Integ, defend Integ
against claimed infringement of the rights of others or determine the scope and
validity of the proprietary rights of others. It is always possible that third
parties may pursue litigation which could be costly to Integ. An adverse
determination in any litigation could:

    - subject Integ to significant liabilities to third parties,

    - require Integ to seek licenses from or pay royalties to third parties, or

    - prevent Integ from manufacturing, selling or using its proposed products.

Any of these alternatives could have a material adverse effect on Integ's
business and prospects.

INTEG DEPENDS ON ITS ABILITY TO ATTRACT AND RETAIN KEY PERSONNEL.

    As an independent company, the success of Integ is dependent in large part
upon the ability of Integ to attract and retain key management and operating
personnel. Qualified individuals are in high demand and are often subject to
competing offers. Integ may not be able to attract and retain the qualified
personnel needed for its business if the merger is not consummated and it
remains independent. The loss of the services of members of Integ's research,
manufacturing or management group or the inability to hire additional personnel
as needed would likely have a material adverse effect on Integ's business and
prospects.

                   THE SPECIAL MEETING OF INTEG SHAREHOLDERS

    The Integ board of directors is soliciting the proxies of its common
shareholders in connection with the special meeting of common shareholders to
vote on the proposed merger.

DATE, TIME AND PLACE OF THE SPECIAL MEETING AND MATTERS TO BE CONSIDERED


    The special meeting of shareholders of Integ will be held at the Minneapolis
Marriott City Center, 30 South 7th Street, Minneapolis, Minnesota 55402 on
January 23, 2001 at 10:00 a.m. local time. At the meeting, Integ will ask the
holders of its common stock:


    1.  to consider and vote on a proposal to approve the agreement and plan of
merger dated as of October 3, 2000, as amended, by and among Inverness, Terrier
and Integ; and

    2.  to transact such other business as may properly come before the special
meeting or any adjournment or postponement.

    Approval of the merger agreement will also constitute approval of the merger
and the other transactions contemplated by the merger agreement. The merger
agreement is attached as Annex A to this proxy statement and prospectus. Please
read it and the other information contained in this proxy statement and
prospectus carefully before deciding how to vote.

RECORD DATE AND SHARES ENTITLED TO VOTE


    Integ's board of directors has fixed the close of business on December 13,
2000 as the record date for determining Integ shareholders entitled to notice of
and to vote at the special meeting. The only outstanding securities of Integ
entitled to vote on the merger are the shares of Integ common stock. Shares of
Integ's Series B preferred stock are not entitled to vote on the proposal to
approve the merger agreement.



    At the close of business on the record date, 9,922,285 shares of Integ
common stock were outstanding and entitled to vote. They were held of record by
approximately 241 shareholders.


VOTE REQUIRED

    To approve the merger and the merger agreement, the Minnesota Business
Corporation Act requires approval of the merger agreement by the affirmative
vote of a majority of the shares of Integ common stock outstanding and entitled
to vote at the special meeting. Some shareholders of Integ, including all of
Integ's directors, who beneficially own 1,405,387 shares, or approximately 15.4%
of the outstanding shares of Integ common stock, have entered into an agreement
with Inverness to vote their shares in favor of the merger agreement and the
merger. As of the record date and the date of this proxy statement and
prospectus, Inverness owned no shares of Integ common stock.

QUORUM; ABSTENTIONS AND BROKER NON-VOTES

    A majority of the shares of Integ common stock outstanding on the record
date must be present at the meeting to establish a quorum. Shareholders may be
present in person or by proxy. Abstentions and broker non-votes each will be
included in determining the number of shares present and voting at the meeting
for the purpose of determining the presence of a quorum. If a quorum is not
present, it is expected that the special meeting will be adjourned or postponed
to solicit additional proxies. Because approval of the merger agreement and the
completion of the merger requires the affirmative vote of a majority of the
outstanding shares of Integ common stock entitled to vote, abstentions and
broker non-votes will have the same effect as votes against the merger agreement
and the completion of the merger. In addition, a failure of an Integ shareholder
to return a proxy will have the effect of a vote against the approval of the
merger agreement.

                                       25
<PAGE>
    THE ACTIONS PROPOSED IN THIS PROXY STATEMENT AND PROSPECTUS ARE NOT MATTERS
THAT CAN BE VOTED ON BY BROKERS HOLDING SHARES FOR BENEFICIAL OWNERS WITHOUT THE
OWNERS' SPECIFIC INSTRUCTIONS. ACCORDINGLY, YOU ARE URGED TO RETURN THE ENCLOSED
PROXY CARD MARKED TO INDICATE YOUR VOTE.

VOTING OF PROXIES; REVOCATION OF PROXIES

    You are requested to complete, date and sign the accompanying proxy card and
promptly mail it to Integ. All properly executed proxies received prior to
taking the vote at the meeting, and not revoked, will be voted as instructed on
the proxy card. As to any business that may properly come before the special
meeting, however, it is intended that proxies, in the form enclosed, will be
voted in respect thereof in accordance with the judgment of the persons voting
these proxies. If no instructions are given, Integ will vote the proxy in favor
of approving the merger agreement. You may revoke your proxy at any time before
it is voted at the meeting by:

    - signing and delivering to the chief financial officer of Integ, a written
      notice, bearing a date later than the date on your proxy, stating that the
      proxy is revoked;

    - signing and delivering to Integ a proxy for the same shares and bearing a
      later date, which will automatically replace any earlier dated proxy card
      that you returned; or

    - attending the special meeting and voting in person. You must vote,
      however, because your attendance at the special meeting, by itself, does
      not revoke your proxy.

    If your broker holds your shares in "street name," your broker will vote
your shares only if you provide instructions on how to vote. Your broker will
provide you directions regarding how to instruct your broker to vote your
shares. Please note, however, that if the holder of record of your shares is
your broker, bank or other nominee and you wish to vote at the meeting, you must
bring a letter from the broker, bank or other nominee confirming that you are
the beneficial owner of the shares.

    You should not send any certificates representing Integ stock with your
proxy. After the merger, you will receive instructions for the surrender and
exchange of your stock certificates.

EXPENSES OF SOLICITATION OF PROXIES


    Integ will assume the cost of solicitation of proxies from you. In addition
to solicitation by mail, the directors, officers and employees of Integ may
solicit proxies from shareholders by telephone, facsimile or in person.
Following the original mailing of the proxies and other soliciting materials,
Integ will request brokers, custodians, nominees and other record holders to
forward copies of the proxy and other soliciting materials to persons for whom
they hold shares of Integ common stock and to request authority for the exercise
of proxies. In such cases, Integ, upon the request of the record holders, will
reimburse such holders for their reasonable expenses. Integ has engaged
Innisfree M&A Incorporated to assist in the solicitation of proxies for the
meeting and will pay Innisfree a fee of approximately $6,500 for this service.


DISSENTERS' APPRAISAL RIGHTS

    In connection with the proposal to approve the merger agreement and the
merger, the shareholders of Integ may, under certain circumstances and by
following procedures prescribed by Minnesota law, exercise dissenters' appraisal
rights and receive cash for their shares of Integ common stock. The failure of a
dissenting shareholder of Integ to follow the appropriate procedures may result
in the termination or waiver of such rights. See the section of this proxy
statement and prospectus titled "The Merger--Dissenters' Appraisal Rights" on
page 41 for a summary of dissenters' appraisal rights and the procedures to
follow to assert these rights.

                                       26
<PAGE>
OTHER MATTERS

    Integ is not aware of any business or matter other than those indicated
above that may be properly presented at the special meeting. If, however, any
other matter properly comes before the special meeting, the proxy holders will,
in their discretion, vote on it in accordance with their best judgment.

RECOMMENDATION OF THE INTEG BOARD OF DIRECTORS

    THE INTEG BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT
AND RECOMMENDS THAT INTEG SHAREHOLDERS VOTE FOR APPROVAL OF THE MERGER
AGREEMENT.

    THE MATTERS TO BE CONSIDERED AT THE SPECIAL MEETING ARE OF GREAT IMPORTANCE
TO THE SHAREHOLDERS OF INTEG. ACCORDINGLY, YOU ARE URGED TO READ AND CAREFULLY
CONSIDER THE INFORMATION PRESENTED IN THIS PROXY STATEMENT AND PROSPECTUS AND TO
COMPLETE, DATE, SIGN AND PROMPTLY RETURN THE ENCLOSED PROXY IN THE ENCLOSED
POSTAGE-PAID ENVELOPE.

    SHAREHOLDERS SHOULD NOT SEND ANY STOCK CERTIFICATES WITH THEIR PROXY CARDS.
A TRANSMITTAL FORM WITH INSTRUCTIONS FOR THE SURRENDER OF YOUR STOCK
CERTIFICATES FOR INTEG COMMON STOCK WILL BE MAILED TO YOU AS SOON AS PRACTICABLE
AFTER COMPLETION OF THE MERGER.

                                   THE MERGER

BACKGROUND OF THE MERGER

    On July 1, 1998, representatives of Integ including Susan L. Critzer, Chief
Executive Officer of Integ and Richard F. Mussmann, Chief Technical Officer of
Integ met with Ron Zwanziger, Chief Executive Officer of Inverness and Tony
Hall, Chief Financial Officer of Inverness, in Minneapolis, Minnesota about the
possibility of engaging in a joint development activity.

    Based on the results of a large-scale internal study, Integ announced in
August 1998 that it would be replacing its infrared measurement system with an
alternate proven measurement technology. Furthermore, Integ announced that it
would explore potential corporate alliances that could expedite this change.


    On August 10, 1998, Ms. Critzer and Mr. Mussmann met with David Scott, Ph.D,
the Managing Director of Inverness, at Inverness' facility in Scotland to
continue discussions of a possible joint development activity. On August 11,
1998, Mark B. Knudson, Ph.D, Chairman of the Board of Integ and Mr. Zwanziger
had additional discussions concerning possible structures for a joint venture.


    Integ engaged U.S. Bancorp Piper Jaffray Inc. on August 26, 1998 to serve as
financial advisor to Integ in connection with the exploration of certain
strategic alternatives, including joint ventures, corporate strategic alliances,
a sale of Integ or other business combinations.


    On September 9, 1998, Jerry McAleer, Vice President of Research and
Development of Inverness, met with Ms. Critzer and Mr. Mussmann at Integ and had
additional discussions concerning the technology of the respective companies.


    In September and November of 1998, Inverness and several other parties
executed confidentiality agreements with Integ and visited Integ to conduct due
diligence in connection with a possible transaction.

    Ms. Critzer updated the board of directors as to progress toward the search
for a partner at a meeting of the board of directors on September 22, 1998.
Representatives of U.S. Bancorp Piper Jaffray also provided an update on the
status of partner search activity to the board.

    On September 28, 1998, representatives of U.S. Bancorp Piper Jaffray sent a
draft term sheet to Mr. Zwanziger concerning a possible joint venture or
acquisition.

    Integ's board of directors met on November 13, 1998. U.S. Bancorp Piper
Jaffray reviewed the status of contacts and discussions with various third
parties identified as possible partners with the board. Management also provided
the board with an update on visits to Integ by third parties.


    On December 1, 1998, Ms. Critzer and Mr. Mussmann from Integ visited Amira
Medical and met with Ms. Karen Drexler, Chief Executive Officer and Joel
Douglas, Chief Technical Officer to tour Amira's facilities and continue
discussions regarding possible collaborations. On December 2, 1998,
Ms. Critzer, Mr. Mussmann and Dr. Knudson met with Mr. Zwanziger and his
financial advisor to outline a tentative joint development program and possible
joint venture structures.


    On December 14, 1998, Integ, through U.S. Bancorp Piper Jaffray, received a
draft term sheet from Amira regarding a potential business alliance. On
December 15, 1998, Mr. Zwanziger sent U.S. Bancorp Piper Jaffray a draft joint
venture term sheet. Both Amira and Inverness were advised that their proposal
would be reviewed with Integ's board of directors.

    On December 18, 1999, U.S. Bancorp Piper Jaffray updated Integ's board of
directors on the progress toward a search for a partner. U.S. Bancorp Piper
Jaffray also outlined the terms tentatively being discussed with Amira and
Inverness. The board did not take any formal action but instructed

                                       28
<PAGE>
management with U.S. Bancorp Piper Jaffray to continue negotiations with both
parties and to continue to explore all strategic alternatives with all possible
parties.

    During the month of January 1999, representatives of Integ and Inverness
continued to have preliminary discussions concerning a possible transaction, but
were unable to reach agreement upon tentative terms and, as a result,
preliminary discussions with Inverness terminated on January 30, 1999.

    The Integ board of directors had a board meeting on February 17, 1999 at
which U.S. Bancorp Piper Jaffray discussed Integ's strategic alternatives. The
board did not take any formal action but instructed management and U.S. Bancorp
Piper Jaffray to continue to explore all strategic alternatives with all
possible parties.

    On February 25, 1999, U.S. Bancorp Piper Jaffray received an updated
alliance proposal from Amira.

    At a meeting of Integ's board of directors on February 26, 1999, management
of Integ briefed the board on Amira's proposal to enter into a strategic
alliance with Integ. The board authorized management of Integ to continue to
negotiate terms of an alliance with Amira. The board also authorized management
to provide notice to a third party that it had received a proposal from Amira as
required by the terms of the confidentiality agreement entered into with that
party.


    On March 10 and 11, 1999, Ms. Critzer, Dr. Knudson and Robert Momsen, a
director of Integ at that time, and representatives of U.S. Bancorp Piper
Jaffray and Dorsey & Whitney, Integ's outside legal counsel, traveled to Palo
Alto, California to meet with Jim Wilson, Chairman of Amira, Ms. Drexler,
Mr. Douglas and Andrew Galligan, Chief Financial Officer of Amira to discuss
tentative terms for a proposed alliance between Amira and Integ and to conduct
due diligence of Amira. Pursuant to the proposed alliance, Integ and Amira would
agree to jointly develop a glucose monitoring device using interstitial fluid.
In consideration for entering into the strategic alliance, Integ would receive
an option to be acquired by Amira for total consideration fixed at the time the
strategic alliance is entered into. This option would not be immediately
exercisable, but would be exercisable by Integ upon the earliest to occur of an
initial public offering by Amira, an acquisition of Amira by a third party or
three years from the date of the strategic alliance. In consideration for
entering into the strategic alliance, Amira would receive certain rights to
Integ's intellectual property in the event that Integ was acquired by a third
party.



    Integ's board of directors held a telephonic meeting on March 11, 1999
during which management updated the board on the status of negotiations with
Amira. Representatives from U.S. Bancorp Piper Jaffray made a presentation to
the board concerning the state of the industry and other strategic alternatives
available to Integ. The board of directors authorized management to enter into
an agreement with Amira in connection with negotiating definitive terms for the
proposed strategic alliance which prohibited Integ from conducting additional
negotiations with any other parties unless Integ received an unsolicited
superior proposal from that party.


    On March 17 and 18, 1999, representatives of Amira Medical and Wilson
Sonsini Goodrich & Rosati, counsel for Amira, traveled to Integ's facilities to
conduct due diligence.

    On March 23, 1999, the third party provided an offer to acquire Integ for
cash. On March 24, 1999, Integ's board of directors held a telephonic meeting to
discuss the offer received. The board concluded that the consideration offered
by the third party was not superior to the consideration offered by Amira and
instructed a representative of U.S. Bancorp Piper Jaffray to communicate that to
the third party.

    On March 25, 1999, the third party provided an offer to acquire Integ for
cash at an improved valuation. Integ's board of directors held a telephonic
meeting on March 26, 1999 to discuss the offer received. In addition, management
of Integ and representatives of U.S. Bancorp Piper Jaffray and

                                       29
<PAGE>
Dorsey & Whitney updated the board with respect to the status of negotiating the
definitive terms of a strategic alliance with Amira. The board concluded that
the improved consideration offered by the third party was not superior to the
consideration offered by Amira and instructed a representative of U.S. Bancorp
Piper Jaffray to communicate that to the third party.

    On March 30, 1999, Mr. Galligan and a representative of Wilson Sonsini
Goodrich & Rosati traveled to Minneapolis, Minnesota to negotiate the final
terms of the alliance between Amira and Integ with management of Integ.


    Integ's board of directors held a telephonic meeting on March 30, 1999 and
management updated the board on the status of negotiating the definitive
agreement on the terms of an alliance with Amira.


    On April 1, 1999, the third party provided an offer to acquire Integ for
cash at a valuation that was higher than the March 25, 1999 offer. Integ's board
of directors held a telephonic meeting to discuss this offer. Representatives of
U.S. Bancorp Piper Jaffray briefed the directors as to their discussions with
the third party and representatives of Dorsey & Whitney discussed the
requirements of the no-shop agreement contained in the letter of intent with
Amira. The board concluded that the terms of the offer from the third party
constituted a superior proposal under the terms of the letter of intent. The
board also authorized Dr. Knudson and Mr. Momsen to advise Mr. Wilson of the
proposal and to negotiate with Mr. Wilson to determine whether Amira would
improve the terms of the proposed alliance. During a telephone call in the
evening of April 1, 1999, Mr. Wilson communicated that Amira would increase the
consideration offered in the event that Integ exercised the option to be
acquired by Amira.


    On April 2, 1999, the Integ board of directors met, was updated by
management of Integ as to the status of discussions with Amira, heard
presentations by, and received an oral fairness opinion, later confirmed in
writing, from U.S. Bancorp Piper Jaffray, to the effect that, as of the date and
subject to limitations and assumptions set forth therein, the consideration
payable to holders of Integ common stock in the merger contemplated by the
proposed option agreement was fair, received a description by Dorsey & Whitney
of the terms of the strategic alliance and authorized the strategic alliance and
related matters. Later that evening, Integ and Amira entered into the alliance
and executed a development agreement and the option agreement.


    On June 7, 2000 Mr. Zwanziger contacted Ms. Critzer to determine Integ's
interest in collaborating with Inverness. On June 13, 2000, Mr. Zwanziger,
Ms. Critzer and Robert S. Nickoloff, a director of Integ, met in Minneapolis,
Minnesota and discussed in general terms what types of collaboration that Integ
might be willing and able to entertain.

    Ms. Critzer briefed the board of directors of Integ of the meeting with
Mr. Zwanziger at a meeting held on June 22, 2000. The board took no formal
action, but authorized Ms. Critzer, Dr. Knudson and Mr. Nickoloff to continue
discussions with Inverness.

    On July 31, 2000, Mr. Zwanziger held a conference call with Ms. Critzer,
Dr. Knudson and Mr. Nickoloff to discuss tentative terms of an acquisition of
Integ. On August 7, 2000, Integ retained U.S. Bancorp Piper Jaffray to assist it
in connection with a possible acquisition by Inverness.


    On August 30, 2000, representatives of Goodwin, Procter & Hoar LLP, counsel
to Inverness, traveled to Minneapolis, Minnesota and conducted a due diligence
review of Integ.


    Throughout the month of September 2000, Ms. Critzer, Dr. Knudson and
Mr. Nickoloff had several conversations with Mr. Zwanziger concerning the
tentative terms of an acquisition. On September 8, 2000, Ms. Critzer updated the
board on the status of discussions with Inverness.

    On September 14, 2000 Integ received an offer to be acquired by Inverness.
Integ's board of directors held a telephonic meeting on September 15, 2000 and
management of Integ updated the board as to the offer received from Inverness.
The board authorized management to negotiate final

                                       30
<PAGE>
terms of the acquisition. The board also authorized management to provide notice
to Amira that Integ had received an offer to be acquired.

    From September 14, 2000 through October 3, 2000, there were various
discussions between lawyers for each of the parties and management of Integ and
Inverness on various issues.


    On October 3, 2000, the Integ board of directors met, was updated by
Ms. Critzer on the status of discussions, heard presentations by, and received
an oral fairness opinion from, U.S. Bancorp Piper Jaffray, which was later
confirmed in writing, to the effect that, as of that date and subject to the
limitations and assumptions therein set forth, the consideration proposed to be
paid to the holders of Integ common stock in the merger in accordance with the
merger agreement was fair to the common shareholders of Integ. The Integ board
also received a description by legal counsel of the terms of the transaction and
authorized the merger agreement and various other related documents and matters.
There were final negotiations on the specific terms of the definitive merger
agreement, which was signed later that evening.


REASONS FOR THE MERGER

    The following discussion of the parties' reasons for the merger contains a
number of forward-looking statements that reflect the current views of Inverness
and Integ with respect to future events that may have an effect on their future
financial performance. Forward-looking statements are subject to risks and
uncertainties. Actual results and outcomes may differ materially from the
results and outcomes discussed in the forward-looking statements. Cautionary
statements that identify important factors that could cause or contribute to
differences in results and outcomes include those discussed or incorporated by
reference in the sections of this proxy statement and prospectus entitled
"Special Note Regarding Forward-Looking Statements" and "Risk Factors."

INVERNESS' REASONS FOR THE MERGER


    In evaluating the proposed merger, the Inverness board of directors reviewed
presentations from management and advisors, including its transaction advisor,
Covington & Associates, and considered the following information and factors:


    - The Inverness board of directors believes that the merger will accelerate
      revenue and earnings growth in the future through the acquisition of the
      technology contained within Integ's LIFEGuide-TM- System of glucose
      measurement.

    - Inverness is anticipating continuing the development and commercialization
      of Integ's proprietary interstitial fluid sampling technology, which
      allows people with diabetes to measure their glucose levels without the
      need to lance a finger or deal with blood.

    - The merger will permit Inverness to increase its focus in the diabetes
      self-test and professional diagnostic product market, including the
      expansion of its related product pipeline, while still maintaining its
      existing presence in women's health and infectious disease self-test and
      professional diagnostic markets.

    - Inverness expects to realize synergies through the acquisition of Integ's
      existing and in-process intellectual property and the elimination of
      redundancies.

    The Inverness board of directors weighed these advantages against potential
risks of the merger, including the rights of Amira Medical in certain of Integ's
intellectual property, including certain exclusive rights with respect to
jointly developed technology. These risks are discussed in the section of this
proxy statement and prospectus entitled "Risk Factors--Risks Relating to the
Merger."

    The foregoing discussion of information and factors considered by the
Inverness board of directors is not intended to be exhaustive but is believed to
include all material factors considered by the

                                       31
<PAGE>
Inverness board of directors. In view of the wide variety of factors considered
by the Inverness board of directors, the Inverness board of directors did not
find it practicable to quantify or otherwise assign relative weight to the
specific factors considered. In addition, the Inverness board did not reach any
specific conclusion on each factor considered, or any aspect of any particular
factor, but conducted an overall analysis of these factors. Individual members
of the Inverness board may have given different weight to different factors.
However, after taking into account all of the factors set forth above, the
Inverness board of directors unanimously agreed that the merger agreement and
the merger were fair to, and in the best long-term interests of, Inverness and
its stockholders and that Inverness should proceed with the merger.

INTEG'S REASONS FOR THE MERGER

    Integ's board of directors consulted with senior management and Integ's
financial and legal advisors and considered a number of factors, including those
set forth below, in reaching its decision to approve the merger agreement and
the transactions contemplated by the merger agreement, and to recommend that
Integ's shareholders vote "FOR" approval of the merger agreement.

    BACKGROUND.  Integ's board of directors was knowledgeable in the progress
that Integ had made in the last few year towards development of its product,
including development progress made in connection with the development and
license agreement with Amira Medical. The board of directors was also
knowledgeable with regard to the additional pre-clinical research recently
conducted by Integ at Amira's request, and was aware of the progress made by
other potential competitors in introducing products that utilized painless
glucose testing. As described under "--Background of the Merger," Integ's board
of directors held numerous meetings during the year preceding approval of the
merger to understand and monitor the progress Integ was making towards
development of an alternative painless glucose testing product under its
agreement with Amira and the progress its potential competitors were making.


    MERGER CONSIDERATION.  In addition to the analysis and presentations by
Integ's financial advisor referred to in "Fairness Opinion of Integ's Financial
Advisor" below, the board of directors looked at the premium represented by the
merger consideration, based upon a contemporaneous five day average share price
of $18.01 of Inverness common stock compared to recent trading prices of Integ
common stock of $2.75 on September 29, 2000, a 22.9% premium, $2.50 on
September 25, 2000, a 35.2% premium, and $1.44 on September 1, 2000, a 134.7%
premium. Integ's board of directors also considered the ability of Integ
shareholders to continue to participate in the growth of the combined company
since the consideration to be received by Integ's shareholders consists of
shares of common stock of Inverness.


    ALLIANCE WITH AMIRA.  Integ's board of directors further considered the
aggregate merger consideration of $20,000,000 and 2,000,000 shares of Amira
common stock available to Integ shareholders pursuant to the option to merge
with a subsidiary of Amira granted under its alliance with Amira. The board
noted that Integ would not be able to exercise this option until the earlier to
occur of:

    - an initial public offering of Amira,

    - a sale of Amira to a third party, or

    - April 2, 2002.

Integ's board considered the likelihood of an initial public offering by Amira
or a sale of Amira to a third party within the near term. The board also noted
that the 2,000,000 shares of Amira common stock that Integ shareholders would
receive were not subject to anti-dilution protection and that the percentage
ownership of Amira that the 2,000,000 shares represented was diluted by a
private financing

                                       32
<PAGE>
round recently completed by Amira. The board also was aware that if Amira is
recapitalized through the subdivision of, combination of, or a stock dividend
on, its outstanding common stock, the 2,000,000 shares would be adjusted in the
same proportion. Integ's board of directors considered that any transaction with
Amira would be a taxable transaction to Integ's shareholders while the merger
with Inverness would be a tax-free transaction. Integ's board of directors also
considered the immediate liquidity that would be available to Integ's
shareholders under the terms proposed by Inverness.


    ADVICE FROM INTEG'S FINANCIAL ADVISOR.  Integ's board of directors
considered the detailed presentations made by U.S. Bancorp Piper Jaffray,
Integ's financial advisor, with respect to the proposed consideration offered to
the holders of Integ common stock in the merger. The board also considered U.S.
Bancorp Piper Jaffray's oral opinion, which was subsequently confirmed in
writing, concluding, as of the date of its opinion, that the merger
consideration to be received by the holders of Integ common stock was fair, from
a financial point of view, to the holders of Integ common stock. The full text
of this opinion is attached to this proxy statement and prospectus as Annex B.


    REVIEW OF PROSPECTS IN REMAINING INDEPENDENT.  Integ's board of directors
considered Integ's financial condition, results of operations and business and
earnings prospects if it were to remain an independent entity in light of
Integ's available cash and the amount of cash necessary to develop and launch a
commercially viable product.

    EFFECT ON EMPLOYEES AND FACILITY.  The board of directors of Integ
considered the possible effect of the merger on the current facility and
employees and compared this to the corresponding risks associated with continued
dependence on funding from Amira Medical.


    CERTAIN TERMS OF THE MERGER AGREEMENT RELATING TO ALTERNATIVE
TRANSACTIONS.  In evaluating the adequacy of the consideration to be received,
the board of directors determined that the merger agreement did not preclude a
third party offer for Integ. In particular, in connection with a proposal more
favorable from a financial point of view than the merger, the merger agreement
permits the board of directors to, if and to the extent required by its
fiduciary duties:


    - provide information to, and engage in discussions or negotiations with, a
      third party that makes an unsolicited proposal; and

    - withdraw its recommendation that the shareholders vote in favor of
      adopting the merger agreement.

    Integ's board of directors also considered that the merger agreement:

    - permits Inverness to terminate the merger agreement if the board of
      directors withdraws its recommendation in favor of the merger with
      Inverness or recommends a superior proposal; and

    - requires Integ to pay a termination fee to Inverness if the merger
      agreement is terminated under some circumstances.

    The board of directors noted that the termination payment provisions of the
merger agreement could have the effect of discouraging alternative proposals for
a business combination between Integ and a third party. However, the board of
directors concluded that the amount of the fee that Integ may be obligated to
pay and the circumstances under which it may be payable, are typical for
transactions of this size and type, are not likely to discourage any such
proposals and were necessary to ensure that Inverness would sign the merger
agreement.


    LIMITED CLOSING CONDITIONS.  The board of directors considered the limited
nature of the closing conditions included in the merger agreement, including
regulatory consents, and the likelihood that the merger agreement would be
approved by Integ's shareholders.


                                       33
<PAGE>

    The foregoing discussion of the information and factors considered by
Integ's board of directors, while not exhaustive, includes the material factors
considered by the board of directors. In view of the variety of factors
considered in connection with its evaluation of the merger, Integ's board of
directors did not find it practicable to, and did not, quantify or otherwise
assign relative or specific weight or values to any of these factors, and
individual directors may have given different weights to different factors.


RECOMMENDATION OF INTEG'S BOARD OF DIRECTORS

    After careful consideration, Integ's board of directors has unanimously
determined that the merger agreement is advisable and in the best interests of
Integ and its shareholders, has unanimously determined that the merger is fair
to, and in the best interests of, the shareholders of Integ, has unanimously
approved the merger agreement, and UNANIMOUSLY RECOMMENDS THAT INTEG
SHAREHOLDERS VOTE "FOR" THE APPROVAL OF THE MERGER AGREEMENT.

FAIRNESS OPINION OF INTEG'S FINANCIAL ADVISOR

    Integ retained U.S. Bancorp Piper Jaffray to act as its financial advisor
and to render to the board of directors an opinion as to the fairness, from a
financial point of view, of the consideration to be received by Integ common
shareholders in the merger.

    U.S. Bancorp Piper Jaffray delivered to the board of directors of Integ on
October 3, 2000 its oral opinion, subsequently confirmed in writing, as of that
date and based upon and subject to the assumptions, factors and limitations set
forth in the written opinion and described below, the consideration proposed to
be received by Integ common shareholders in the proposed merger was fair, from a
financial point of view, to those shareholders. A copy of U.S. Bancorp Piper
Jaffray's written opinion is attached to this proxy statement and prospectus as
Annex B and is incorporated into this proxy statement and prospectus by
reference.

    While U.S. Bancorp Piper Jaffray rendered its opinion, provided certain
analyses to the board of directors and participated in negotiations with
Inverness, U.S. Bancorp Piper Jaffray was not requested to and did not make any
recommendation to the board of directors as to the specific form or amount of
the consideration to be received by Integ shareholders in the proposed merger,
which was determined by Integ and Inverness. U.S. Bancorp Piper Jaffray's
written opinion, which was directed to the board of directors, addresses only
the fairness, from a financial point of view, of the proposed consideration to
be received by Integ common shareholders in the proposed merger, does not
address Integ's underlying business decision to participate in the merger and
does not constitute a recommendation to any Integ shareholder as to how a
shareholder should vote with respect to the merger.

    In arriving at its opinion, U.S. Bancorp Piper Jaffray reviewed:

    - a draft of the merger agreement dated October 1, 2000,

    - publicly available financial, operating and business information related
      to Inverness and Integ,

    - publicly available market and securities data of Inverness and Integ,

    - analyst reports relating to Inverness and Integ,

    - forecast financial information of Integ and Inverness as a combined
      company furnished by Integ and Inverness management, and

    - the Development and License Agreement and the Option Agreement with Amira
      Medical and other information concerning Amira Medical more fully
      described below.

                                       34
<PAGE>
    In addition, U.S. Bancorp Piper Jaffray visited facilities of Integ and
Inverness and conducted discussions with members of senior management of both
Inverness and Integ concerning the financial condition, current operating
results and business outlook of Inverness, Integ and the combined company
following the merger.

    In delivering its opinion to the board of directors of Integ, U.S. Bancorp
Piper Jaffray presented various analyses and other information material to its
opinion. The following is a summary of this presentation:

IMPLIED CONSIDERATION

    Giving effect to the proposed conversion ratio and the current trading price
of Inverness common stock at the close of trading on October 3, 2000 of $18.88,
U.S. Bancorp Piper Jaffray calculated an implied consideration per share of
Integ common stock of $3.52 and an aggregate implied consideration for the
common equity of Integ of approximately $38.0 million.

INTEG STOCK TRADING ANALYSIS

    U.S. Bancorp Piper Jaffray reviewed the stock trading history of Integ. U.S.
Bancorp Piper Jaffray presented the recent common stock trading information

</TABLE>

    U.S. Bancorp Piper Jaffray also presented graphs illustrating daily stock
price and volume performance of Integ over the prior year.

ANALYSIS OF OPTION AGREEMENT

    U.S. Bancorp Piper Jaffray advised the Integ board of directors of certain
factors relating to Integ and the proposed merger, which affected its review and
analyses in certain material respects. As a development stage company, Integ has
no historical operating results upon which to base a valuation analysis as a
going concern. Nor was U.S. Bancorp Piper Jaffray furnished any forecasts of
Integ future operating results, nor, in light of recent developments involving
its joint development activity with Amira Medical and Integ's current financial
and operating condition, could such a forecast be reasonably prepared for Integ
on a stand alone, going concern basis. Further, U.S. Bancorp Piper Jaffray was
not furnished, nor requested to perform, any appraisals or valuations of
specific assets or liabilities of Integ, including its technology portfolio.


    In view of the foregoing, U.S. Bancorp Piper Jaffray, with the concurrence
of the Integ board of directors, concluded the principal source of Integ
shareholder value against which the fairness of the proposed merger
consideration could be reasonably evaluated was the implied value of the
consideration payable to Integ shareholders in a possible merger with Amira
Medical in accordance with the Option Agreement with Amira Medical. Amira
Medical is a privately held company. Amira Medical does not provide its
historical or forecast results of operations to the public, nor, since the
execution of the Option Agreement, has such information been provided by Amira
Medical to Integ or U.S. Bancorp Piper Jaffray. Integ management assisted U.S.
Bancorp Piper Jaffray in developing an estimated forecast for Amira Medical for
the calendar year ending 2004 for use in evaluating the implied value of Integ
arising out of a possible Amira Merger. U.S. Bancorp Piper Jaffray developed
assumptions regarding the possible timing of an initial public offering of Amira
Medical common stock.


                                       35
<PAGE>
    Using this information, U.S. Bancorp Piper Jaffray presented several
analyses from which it calculated a range of possible implied values for the
equity interest in Amira Medical payable to Integ shareholders pursuant to a
possible merger with Amira Medical in accordance with the Option Agreement.
These analyses included an initial public offering valuation, a discounted cash
flow valuation, a discounted future equity valuation and recent third party
financing valuation.

    - INITIAL PUBLIC OFFERING VALUATION. Based on recent medical company initial
      public offering activity, U.S. Bancorp Piper Jaffray calculated an
      estimated post-initial public offering value for Amira Medical of
      $300 million, of which it estimated Integ shareholders would own 4.8%.
      Applying a discount rate in order to present value from an assumed initial
      public offering date the value of this Integ shareholder interest and a
      further discount factor to account for the illiquidity of this interest on
      a present value basis, U.S. Bancorp Piper Jaffray calculated an estimated
      value for this interest of $10.457 million.

    - DISCOUNTED CASH FLOW VALUATION. Based on a discount rate of 35.0% and
      using a terminal value multiple of 13.0x projected calendar 2004 operating
      income, U.S. Bancorp Piper Jaffray calculated a discounted cash flow value
      of Amira Medical of $14.183 million. Giving effect to the estimated
      hypothetical 4.8% interest of Integ shareholders in Amira Medical and an
      illiquidity and control discount to account for the illiquidity of this
      interest on a present value basis and minority interest of these
      shareholders, U.S. Bancorp Piper Jaffray calculated an estimated value for
      this interest of $9.219 million.

    - DISCOUNTED FUTURE EQUITY VALUATION. U.S. Bancorp Piper Jaffray calculated
      an implied future stock price at December 31, 2001 for Amira Medical
      common stock based on projected fiscal year 2002 earnings and an estimated
      multiple of earnings. Applying an estimated 5.7% pre-initial public
      offering ownership stake in Amira Medical for Integ shareholders, present
      valuing that interest and adjusting for assumed illiquidity on a present
      value basis, U.S. Bancorp Piper Jaffray calculated an estimated value for
      this interest of $11.650 million.


    - RECENT FINANCING. U.S. Bancorp Piper Jaffray was also aware that Amira
      Medical had recently completed a private round of preferred stock
      financing. Based on the estimated pricing of this round and the shares
      issued, U.S. Bancorp Piper Jaffray calculated an estimated value for the
      interest of Integ shareholders of $11.3 million.


    Adding these values together with the estimated present value of the cash
component of a possible Amira Merger, or $15.749 million, U.S. Bancorp Piper
Jaffray indicated a range of implied values for the equity of Integ based on the
Option Agreement as follows: high, $27.355 million; low, $24.968 million; and
mean, $26.395 million. These values were compared to the implied value of
$38.0 million payable in the merger with Inverness.

PREMIUMS PAID ANALYSIS

    U.S. Bancorp Piper Jaffray reviewed publicly available information for a
group of selected pending or completed acquisition transactions since

ANALYSIS OF INVERNESS COMMON STOCK

    U.S. Bancorp Piper Jaffray reviewed general background information
concerning Inverness. U.S. Bancorp Piper Jaffray presented publicly available
analyst estimates and ratings of Inverness common stock, recent financial and
operating results and outlook, and the stock price and volume over selected
periods. U.S. Bancorp Piper Jaffray also reviewed the stock trading history of
Inverness common stock at the dates or for the periods indicated below.

</TABLE>

    In addition, U.S. Bancorp Piper Jaffray illustrated the relative stock price
performance of Inverness against various market indices.

    In reaching its conclusion as to the fairness of the merger consideration
and in its presentation to the board of directors, U.S. Bancorp Piper Jaffray
did not rely on any single analysis or factor described above, assign relative
weights to the analyses or factors considered by it, or make any conclusion as
to how the results of any given analysis, taken alone, supported its opinion.
The preparation of a fairness opinion is a complex process and not necessarily
susceptible to partial analysis or summary description. U.S. Bancorp Piper
Jaffray believes that its analyses must be considered as a whole and that
selection of portions of its analyses and of the factors considered by it,
without considering all of the factors and analyses, would create a misleading
view of the processes underlying the opinion.

    The analyses of U.S. Bancorp Piper Jaffray are not necessarily indicative of
actual values or future results, which may be significantly more or less
favorable than suggested by the analyses. Analyses relating to the value of
companies do not purport to be appraisals or valuations or necessarily reflect
the price at which companies may actually be sold. No company or transaction
used in any analysis for purposes of comparison is identical. Accordingly, an
analysis of the results of the comparisons is not mathematical; rather, it
involves complex considerations and judgments about differences in the companies
and transactions compared and other factors that could affect the public trading
or transactional value of the companies. Other than one party that it was
authorized to contact and did contact, U.S. Bancorp Piper Jaffray was not
authorized to solicit, and did not solicit, other purchasers of Integ or
alternative transactions to the merger with Inverness. Pursuant to its
engagement in late 1998 and early 1999, which resulted in the Amira Medical
agreements, U.S. Bancorp Piper Jaffray was active on behalf of Integ in
soliciting interest for a possible strategic or other combination with Integ as
described above under "Background of the Merger."

                                       37
<PAGE>
    For purposes of its opinion, U.S. Bancorp Piper Jaffray relied upon and
assumed the accuracy, completeness and fairness of the financial statements and
other information provided to it by Integ and Inverness or otherwise made
available to it and did not assume responsibility for the independent
verification of that information. Information prepared for financial planning
purposes was not prepared with the expectation of public disclosure. U.S.
Bancorp Piper Jaffray relied upon the assurances of management of Integ that the
information provided to it by Integ and Inverness, including, without
limitation, information furnished by Integ concerning Amira Medical, was
prepared on a reasonable basis, the financial planning data and other business
outlook information reflects the best currently available estimates of
management, and management was not aware of any information or facts that would
make the information provided to U.S. Bancorp Piper Jaffray incomplete or
misleading.

    For purposes of its opinion, U.S. Bancorp Piper Jaffray assumed that the
merger will constitute a reorganization for federal income tax purposes and will
be treated as a purchase for accounting purposes. U.S. Bancorp Piper Jaffray
also assumed that, in the course of obtaining the necessary regulatory approvals
and consents for the merger, no restrictions will be imposed that have a
material adverse effect on the contemplated benefits of the merger to Integ and
its common shareholders.

    U.S. Bancorp Piper Jaffray assumed the Option Agreement remained in full
force and effect, without amendment, and was enforceable by the parties thereto
in accordance with its terms. The opinion of U.S. Bancorp Piper Jaffray
addressed solely the fairness of the stock consideration to be paid to holders
of Integ common stock in the merger and did not address any other term or
agreement relating to the merger. Without limiting the generality of the
foregoing, U.S. Bancorp Piper Jaffray made no evaluation of the terms pursuant
to which outstanding shares of Series B preferred stock would be redeemed or
pursuant to which Inverness would extend financing to Integ in accordance with
the loan agreement.

    In arriving at its opinion, U.S. Bancorp Piper Jaffray did not perform any
appraisals or valuations of any specific assets or liabilities of Integ or
Inverness, and was not furnished with any such appraisals or valuations. U.S.
Bancorp Piper Jaffray analyzed Integ as a going concern and accordingly
expressed no opinion as to its liquidation value. U.S. Bancorp Piper Jaffray
expressed no opinion as to the price at which shares of Integ or Inverness
common stock have traded or at which the shares of Integ, Inverness or the
combined company may trade at any future time. The opinion is based on
information available to U.S. Bancorp Piper Jaffray and the facts and
circumstances as they existed and were subject to evaluation on the date of the
opinion. Events occurring after that date could materially affect the
assumptions used in preparing the opinion. U.S. Bancorp Piper Jaffray has not
undertaken to and is not obligated to affirm or revise its opinion or otherwise
comment on any events occurring after the date it was given.

    U.S. Bancorp Piper Jaffray, as a customary part of its investment banking
business, evaluates businesses and their securities in connection with mergers
and acquisitions, underwritings and secondary distributions of securities,
private placements and valuations for estate, corporate and other purposes. The
Board of Directors selected U.S. Bancorp Piper Jaffray because of its expertise,
reputation and familiarity with the medical technology industry in general and
with Integ in particular. U.S. Bancorp Piper Jaffray maintains a market in and
provides research coverage on the common stock of Integ. In the ordinary course
of its business, U.S. Bancorp Piper Jaffray and its affiliates may actively
trade securities of Integ for their own accounts or the accounts of their
customers and, accordingly, may at any time hold a long or short position in
those securities. U.S. Bancorp Piper Jaffray has provided investment banking
services to Integ in the past for which it received customary fees.

    Under the terms of the engagement letter dated August 7, 2000, Integ has
agreed to pay U.S. Bancorp Piper Jaffray a fee equal to $750,000 upon
consummation of the merger for its financial advisory services, and $400,000 for
rendering its opinion, which will be credited against payment of the fee for
financial advisory services. The contingent nature of the financial advisory fee
may have created

                                       38
<PAGE>
a potential conflict of interest in that Integ would be unlikely to consummate
the merger unless it had received the opinion of U.S. Bancorp Piper Jaffray.
Whether or not the transaction is consummated, Integ has agreed to pay the
reasonable out-of-pocket expenses of U.S. Bancorp Piper Jaffray and to indemnify
U.S. Bancorp Piper Jaffray against liabilities incurred. These liabilities
include liabilities under the federal securities laws in connection with the
engagement of U.S. Bancorp Piper Jaffray by the board of directors.

INTERESTS OF INTEG'S DIRECTORS AND OFFICERS IN THE MERGER

    When you are considering the recommendation of Integ's board of directors
with respect to approving the merger, you should be aware that the directors and
officers of Integ have interests in the merger and participate in arrangements
that are different from, or are in addition to, those of Integ shareholders
generally. The Integ board was aware of these interests and considered them,
among other matters, when they approved the merger agreement. These interests
include the following:

ACCELERATED VESTING OF OPTIONS

    All outstanding options to purchase Integ stock that are unvested as of the
date of the merger will accelerate and become fully vested and exercisable
immediately prior to the closing of the merger. The number and shares of Integ
common stock covered by unvested options held by directors and executive
officers as of October 3, 2000 was 406,724 shares. Pursuant to the terms of the
merger agreement, all options to purchase Integ common stock will be assumed by
Inverness in the merger and converted into options to purchase Inverness common
stock. For further discussion about the treatment of Integ options in the
merger, see the section of this proxy statement and prospectus entitled "The
Merger Agreement--Integ Stock Options and Warrants" on page 46.

CHANGE OF CONTROL/SEVERANCE AGREEMENTS

    Susan L. Critzer, a director and chief executive officer of Integ, and
Richard F. Mussmann, chief technology officer of Integ, have employment
agreements that provide for certain benefits if they are terminated by Inverness
without cause or if they terminate their employment for good reason following a
change of control. The merger with Inverness will constitute a change of
control. Upon such termination, each of Ms. Critzer and Mr. Mussmann are
entitled to receive a cash payment equal to 12 times her or his average monthly
salary as in effect in the month prior to the change of control, which amount
includes salary and bonus pro rated for that period.

REIMBURSEMENT FOR EXCISE TAXES

    Payments or other benefits, including the acceleration of the exercisability
of options, may be compensatory payments that are contingent on a change of
control and when made to certain defined individuals will be parachute payments
within the meaning of section 280G of the Internal Revenue Code. Section 280G
provides that if parachute payments to an employee equal or exceed three times
the employee's "base amount," the average annual compensation over the five
taxable years preceding the taxable year in which the change of control occurs,
the excess of the parachute payment over the employee's base amount will not be
deductible by Integ and will be subject to an excise tax payable by the
employee.


    The value of the acceleration of vesting under Integ's stock option plans
may result in excess parachute payments to some Integ employees under
section 280G of the Internal Revenue Code. Integ's board of directors has
adopted a resolution that will provide for payments to these employees in an
amount that, after deducting all federal, state and local taxes, will equal the
excise tax payable by the employees. The purpose of these resolutions is to
assure that employees retain the economic value of the stock options granted by
Integ.


                                       39
<PAGE>
INDEMNIFICATION


    Integ officers and directors are entitled to continuing indemnification
against some liabilities by virtue of provisions contained in Integ's articles
of incorporation and the merger agreement. The merger agreement provides for the
maintenance of directors' and officers' insurance for a period of not less than
six years after the effective time of the merger. For more information on the
extent of the indemnification, see the section of this proxy statement and
prospectus on page 53 entitled "The Merger Agreement--Officers and Directors
Indemnification."


WARRANTS

    At the effective time of the merger, Inverness will assume all outstanding
warrants to purchase shares of Integ common stock. This amount includes warrants
to purchase 87,845 shares of Integ stock at $4.13 per share held by affiliates
of an Integ director. See the section of the proxy statement and prospectus
entitled "The Merger Agreement--Integ Stock Options and Warrants" on page 46 for
further discussion about the treatment of Integ warrants in the merger.

PURCHASE OF INTEG SERIES B PREFERRED STOCK


    On February 15, 2000, Integ entered into a financing arrangement with Amira
Medical pursuant to which Integ borrows money from Amira and in exchange issues
to Amira a number of shares of Integ Series B preferred stock that is determined
by dividing the amount borrowed by the closing price of Integ's common stock on
the day of the borrowing. The maximum number of shares of Series B preferred
stock that may be issued pursuant to this arrangement is 3,000,000, and through
November 30, 2000, Integ had issued to Amira a total of 1,983,123 shares of
Series B preferred stock.



    The charter documents of Integ relating to the Series B preferred stock
provide that if there is a change of control of Integ, which will occur as a
result of the merger, the Series B preferred stock must be redeemed for either
cash or Integ common stock at a price equal to the amount borrowed by Integ plus
a 10% premium. Integ intends to redeem the Series B preferred stock for cash. As
of November 30, 2000, the 1,983,123 shares of Series B preferred stock
outstanding would be required to be redeemed for a total price of $4,977,266.87.
Under the terms of the merger agreement, Inverness has agreed to fund the
redemption for cash of all outstanding shares of the Series B preferred stock.



    The financing arrangement obligates Amira to continue to provide funding to
Integ to pay expenses incurred in accordance with Integ's Year 2000 budget. If
Amira defaults in its funding obligations before the effective time of the
merger, then Integ is entitled to redeem the outstanding shares of Series B
preferred stock for $0.01 per share.


EFFECT OF MERGER ON INTEG INTELLECTUAL PROPERTY


    The consummation of the merger will trigger certain significant provisions
set forth in the development and license agreement that Integ entered into with
Amira Medical in April 1999. This agreement provides for the joint development
of a new generation of home glucose monitoring tests that would combine Integ's
proprietary interstitial fluid sampling technology with Amira's glucose
measurement technologies. In addition, the agreement addresses the rights of the
parties with respect to each party's intellectual property in the event one of
the parties merges with another party. The agreement provides that if Integ
merges with a third party, such as Inverness, then upon the closing of the
merger, Integ automatically will grant to Amira an exclusive, perpetual,
non-terminable and transferable license to all Integ intellectual property
relating to glucose monitoring using interstitial fluid developed after
April 2, 1999 and through the date of the closing of the merger and a
co-exclusive, perpetual, non-terminable and transferable license to all Integ
intellectual property relating to glucose monitoring using interstitial fluid,
other than its infrared technology, in existence as of April 2, 1999. Upon the
closing of the merger, the development and license agreement will be


                                       40
<PAGE>

terminated. These provisions mean that, at the closing of the merger, Inverness
will receive no rights to any Integ intellectual property relating to glucose
monitoring using interstitial fluid developed after April 2, 1999. In addition,
with respect to all Integ intellectual property relating to glucose monitoring
using interstitial fluid developed up to and through April 2, 1999, including
all patents owned and patent applications pending, Inverness, as the successor
to Integ, will receive a co-exclusive license with Amira.


    Inverness does not expect that the agreement with Amira, and the
consequences of the merger pursuant to the agreement, will affect Inverness'
plans to use the Integ intellectual property in the future because Inverness
intends to utilize only the Integ intellectual property that was in existence or
pending as of April 2, 1999. This intellectual property includes Integ's patents
relating to the LIFEGuide-TM- System and Integ's proprietary interstitial fluid
sampling.

POST-CLOSING CAPITALIZATION


    Following the merger, Inverness will have approximately 31,018,700 shares of
common stock outstanding. Stockholders of Inverness before the merger will own
approximately 93.9% of the total shares outstanding after the merger and Integ's
current shareholders will own approximately 6.1%.


    All of the percentages calculated above do not take into account the
exercise of any outstanding stock options or warrants that would result in the
issuance of additional common equity of Integ or Inverness.

ACCOUNTING TREATMENT

    Inverness will account for the acquisition of Integ as an asset acquisition.
Under this method of accounting, the assets and liabilities of Integ, including
intangible assets, will be recorded at their fair values. The results of
operations and cash flows of Integ will be included in Inverness' financial
statements following the completion of the merger. Inverness expects that it
will allocate a substantial portion of the purchase price to Integ's in-process
research and development which, under generally accepted accounting principles,
will be expensed by Inverness immediately following completion of the merger.
The remainder of the purchase price will be amortized over a 10 year period.

DISSENTERS' APPRAISAL RIGHTS

    Sections 302A.471 and 302A.473 of the Minnesota Business Corporation Act
provide each shareholder of Integ the right to dissent from the merger and
obtain payment for the "fair value" of the shareholder's shares following the
consummation of the merger.


    The following summary of the applicable provisions of sections 302A.471 and
302A.473 of Minnesota law does not purport to be a complete statement of the
provisions and is qualified in its entirety by reference to the full texts of
these sections attached as Appendix C to this proxy statement and prospectus.
Any shareholder who wishes to exercise dissenters' appraisal rights, or who
wishes to preserve the right to do so, should review these sections carefully
because failure to comply with the procedures set forth in the sections will
result in the loss of dissenters' appraisal rights.


    Under Minnesota law, shareholders of Integ have the right, by fully
complying with the applicable provisions of sections 302A.471 and 302A.473, to
dissent with respect to the merger and to receive from Integ payment in cash of
the "fair value" of their shares after the merger is completed. The term "fair
value" means the value of the shares immediately before the effective date of
the merger without any appreciation or depreciation in anticipation of the
merger.


    All references in sections 302A.471 and 302A.473 and in this summary to a
"shareholder" are to a record holder of the shares as to which dissenters'
appraisal rights are asserted. A record holder is a shareholder who held Integ
common stock at the close of business on December 13, 2000. A person


                                       41
<PAGE>

having beneficial ownership of shares that are held of record in the name of
another person, such as a broker, nominee, trustee or custodian, must act
promptly to cause the record holder to follow the steps summarized below
properly and in a timely manner in order to prefect any dissenters' appraisal
rights the beneficial owner may have.


    Shareholders of record who desire to exercise their dissenters' appraisal
rights must satisfy all of the following conditions. A written notice of intent
to demand fair value for shares must be mailed or delivered to the executive
offices of Integ before the shareholder vote is taken to approve the merger
agreement. This written demand must be in addition to and separate from any
proxy or vote against approval of the merger agreement. Voting against,
abstaining from voting or failing to vote to approve the merger agreement does
not constitute a demand for appraisal within the meaning of Minnesota law.

    Shareholders electing to exercise their dissenters' appraisal rights under
Minnesota law must not vote for approval of the merger agreement. A
shareholder's failure to vote against approval of the merger agreement will not
constitute a waiver of dissenters' appraisal rights. However, if a shareholder
returns a signed proxy but does not specify a vote against approval of the
merger agreement or direction to abstain, the proxy will be voted for approval
of the merger agreement, and the shareholder's dissenters' appraisal rights will
be waived.

    A shareholder must assert dissenters' appraisal rights with respect to all
of the shares registered in the holder's name except where certain shares are
beneficially owned by another person but registered in the holder's name. If a
record owner, such as a broker, nominee, trustee or custodian, wishes to dissent
with respect to shares beneficially owned by another person, the shareholder
must dissent with respect to all of the shares and must disclose the name and
address of the beneficial owner on whose behalf the dissent is made. A
beneficial owner of those shares who is not the record owner of such shares may
assert dissenters' appraisal rights as to shares held on that person's behalf,
provided that the beneficial owner submits a written consent of the record owner
to Integ at or before the time the dissenters' appraisal rights are asserted.

    A shareholder who elects to exercise dissenters' appraisal rights must mail
or deliver a written demand, before the vote is taken on approval of the merger
agreement, to the Chief Financial Officer of Integ at 2800 Patton Road, St.
Paul, Minnesota 55113. The written demand should specify the shareholder's name
and mailing address, the number of shares owned and that the shareholder intends
to demand the fair value of its, his or her shares.

    After approval of the merger agreement by the shareholders at the special
meeting, Integ will send a written notice to each shareholder who delivered a
written demand for dissenters' appraisal rights. The notice will contain the
address to which the shareholder must send a demand for payment and the stock
certificates in order to obtain payment and the date by which they must be
received and other related information.


    In order to receive fair value for a dissenting shareholder's shares, the
shareholder must, within 30 days after the date Integ gives the notice described
in the preceding paragraph, demand payment and send the stock certificates, and
all other information specified in the notice from Integ, to the address
specified in the notice. A dissenting shareholder will retain all rights as a
shareholder until the effective date of the merger. After a valid demand for
payment and the related stock certificates and other information is received, or
after the effective date of the merger, whichever is later, Integ will remit to
each dissenting shareholder who has complied with the statutory requirements the
amount that Integ estimates to be the fair value of the dissenting shareholder's
shares, with interest starting five days after the effective date of the merger
at a rate prescribed by statute. Integ will also send its closing balance sheet
and statement of income for the fiscal year ending no more than 16 months before
the effective date of the merger, together with the latest available interim
financial statement, an estimate of the fair value of the shareholder's shares
and a brief description of the method used to


                                       42
<PAGE>

reach the estimate and a brief description of the procedure to be followed if
the dissenting shareholder decides to make a demand for a supplemental payment.
Copies of sections 302A.471 and 302A.473 of the Minnesota Business Corporation
Act are attached hereto as Annex C.


    If the dissenting shareholder believes that the amount remitted by Integ is
less than the fair value of the holder's shares plus interest, the shareholder
may mail or deliver written notice to Integ of the holder's own estimate of the
fair value of the shares, plus interest, within 30 days after the mailing date
of the remittance and demand payment of the difference. This notice must be
delivered to the executive office of Integ at the address set forth above. A
shareholder who fails to give such written notice within this time period is
entitled only to the amount remitted by Integ.


    Within 60 days after receipt of a demand for supplemental payment, Integ
must either pay the shareholder the amount demanded or agreed to by the
shareholder after discussion with Integ, or petition a court for the
determination of the fair value of the shares, plus interest. The petition must
name as parties all shareholders who have demanded supplemental payment and have
not reached an agreement with Integ. The court, after determining that the
shareholder or shareholders in question have complied with all the statutory
requirements, may use any valuation method or combination of methods it deems
appropriate to use, whether or not used by Integ or the dissenting shareholder,
and may appoint appraisers to recommend the amount of the fair value of the
shares. The court's determination will be binding on all shareholders who
properly exercised dissenters' appraisal rights and did not agree with Integ as
to the fair value of the shares. Dissenting shareholders are entitled to
judgment for the amount by which the court-determined fair value per share, plus
interest, exceeds the amount per share, plus interest, remitted to the
shareholders by Integ. The shareholders will not be liable to Integ for any
amounts paid by Integ that exceed the fair value of the shares as determined by
the court, plus interest. The costs and expenses of such a proceeding, including
the expenses and compensation of any appraisers, will be determined by the court
and assessed against Integ, except that the court may, in its discretion, assess
part or all of those costs and expenses against any shareholder whose action in
demanding supplemental payment is found to be arbitrary, vexatious or not in
good faith. The court may award fees and expenses to an attorney for the
dissenting shareholders out of the amount, if any, awarded to these
shareholders. Fees and expenses of experts or attorneys may also be assessed
against any person who acted arbitrarily, vexatiously or not in good faith in
bringing the proceeding.


    Shareholders considering whether to exercise dissenters' appraisal rights
should bear in mind that the fair value of their shares determined under
sections 302A.471 and 302A.473 of the Minnesota Business Corporation Act could
be more than, the same as or less than the consideration they would receive
pursuant to the merger agreement if they did not seek appraisal of their shares.

    Cash received pursuant to the exercise of dissenters' appraisal rights may
be subject to federal or state income tax. ANY HOLDER WHO FAILS TO COMPLY FULLY
WITH THE STATUTORY PROCEDURE SUMMARIZED ABOVE WILL FORFEIT ALL RIGHTS OF DISSENT
AND INSTEAD EACH OUTSTANDING SHARE OF INTEG COMMON STOCK HELD BY THAT HOLDER
WILL BE CANCELED AND CONVERTED INTO THE RIGHT TO RECEIVE INVERNESS COMMON STOCK
UNDER THE TERMS OF THE MERGER AGREEMENT.

RESTRICTIONS ON RESALE OF INVERNESS COMMON STOCK BY AFFILIATES


    The shares of Inverness common stock to be received by Integ shareholders in
the merger have been registered under the Securities Act and, except as
described in this paragraph, may be freely traded without restriction. The
shares of Inverness common stock to be issued in the merger and received by
persons who are considered to be "affiliates," as that term is used in Rule 145
under the Securities Act, of Integ before the merger may be resold by them only
in transactions permitted by the resale provisions of Rule 145 under the
Securities Act or as otherwise permitted under the Securities Act. Affiliates of
Integ for this purpose include individuals or entities that control, are
controlled by, or


                                       43
<PAGE>

are under common control with, Integ and are expected to include the directors
and executive officers of Integ and holders of 10% or more of Integ common
stock. These affiliates or their brokers risk being characterized as
"underwriters" when they sell shares of Inverness stock received in the merger.
The United States securities laws require registration of shares sold by
underwriters. An affiliate and its broker can avoid being characterized as an
underwriter and, therefore, avoid the Securities Act registration requirements
by selling shares in compliance with Rule 145. This proxy statement and
prospectus does not cover resales of Inverness common stock received by any
person upon completion of the merger, and no person is authorized to make any
use of this proxy statement and prospectus in connection with any such resale.


DELISTING AND DEREGISTRATION OF INTEG COMMON STOCK FOLLOWING THE MERGER

    If the merger is completed, shares of Integ's common stock will be delisted
from the Nasdaq National Market and will be deregistered under the Exchange Act.

LISTING OF INVERNESS COMMON STOCK TO BE ISSUED IN THE MERGER

    The listing on the American Stock Exchange of the shares of Inverness common
stock to be issued in the merger is a condition to the closing of the merger.

    THE FOLLOWING IS A BRIEF SUMMARY OF THE SIGNIFICANT PROVISIONS OF THE MERGER
AGREEMENT BETWEEN INVERNESS AND INTEG. THIS SUMMARY IS NOT COMPLETE AND IS
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE COPY OF THE MERGER AGREEMENT
ATTACHED TO AND INCORPORATED INTO THIS PROXY STATEMENT AND PROSPECTUS AS ANNEX
A. YOU SHOULD READ THE MERGER AGREEMENT CAREFULLY AND IN ITS ENTIRETY.

GENERAL

    The merger agreement provides for a merger of Integ with and into Terrier
Acquisition Corp., a newly formed, wholly owned subsidiary of Inverness. The
surviving company will be Terrier, which will remain a wholly owned subsidiary
of Inverness.

MERGER CONSIDERATION

    In the merger, each outstanding share of Integ common stock, par value $.01
per share, will be converted into the right to receive a fixed number of shares
of common stock of Inverness based on an exchange ratio calculated as follows:

<TABLE>
<S>               <C>                                                          <C>
                                                                                  aggregate exercise
                                                                                 price of Integ stock
                       (average closing price of Inverness common stock X        options and warrants
                                         1,900,000) +                            options and warrants
                    ---------------------------------------------------------------------------------
exchange ratio =                     average closing price of Inverness common stock
                  -------------------------------------------------------------------------------------
                        total number of shares of Integ common stock outstanding immediately prior
                             to the effective time of the merger + the total number of shares
                                issuable upon exercise of Integ stock options and warrants
</TABLE>

    For the purpose of calculating the exchange ratio, the average closing price
for Inverness common stock will be computed by averaging the closing sale prices
of Inverness common stock on the American Stock Exchange for the five trading
days immediately preceding the effective time of the merger.

    In general, the exchange ratio has been formulated to provide that an
aggregate number of 1,900,000 shares of Inverness common stock, net of exercise
amounts attributable to the options and warrants, will be issued to:

    - existing holders of shares of Integ common stock;

    - holders of options to purchase shares of Integ common stock; and

    - holders of warrants to purchase shares of Integ common stock.


However, since many of the variables necessary to determine the exchange ratio
will not be determined until immediately prior to the effective time of the
merger, the precise exchange ratio will not be determined until immediately
prior to the effective time of the merger. The average closing sale price of
Inverness common stock for the five trading days prior to December 13, 2000, the
record date, was $34.0752 per share. Also, as of that date, there were 9,922,285
shares of Integ common stock outstanding, and options and warrants to purchase
2,147,421 shares of common stock with exercise prices per share ranging from
$0.81 to $7.60. Accordingly, if the effective time of the merger were the record
date, the exchange ratio would equal approximately .1734.



    No fractional shares of Inverness common stock will be issued in connection
with the merger. Instead, you will receive an amount of cash, without interest
and rounded to the nearest cent, determined by multiplying the average closing
price of Inverness common stock by the fraction of a share of Inverness common
stock that you would have received if fractional shares were issuable. Any


                                       45
<PAGE>

cash and any Inverness stock certificates remaining unclaimed for more than one
year will be delivered to Terrier.


    The conversion of Integ common stock described in this section is not
applicable to shares held by Inverness or Terrier whose shares, if any, will be
canceled, or to dissenting Integ shareholders who effectively exercise their
dissenters' appraisal rights as described in this proxy statement and
prospectus.

INTEG STOCK OPTIONS AND WARRANTS


    Each outstanding Integ stock option, whether vested or unvested, or warrant
to purchase shares of Integ common stock will be assumed by Inverness and become
an option or warrant, as applicable, to acquire a number of shares of Inverness
common stock equal to the number of shares of Integ common stock subject to the
option or warrant immediately prior to the effective time multiplied by the
exchange ratio used to determine the fraction of a share of Inverness common
stock to be received by Integ shareholders in connection with the merger,
rounded down to the nearest whole number of shares for options and rounded to
the nearest whole share for warrants. The new exercise price of the option or
warrant shall be adjusted to equal the exercise price of the option or warrant
divided by the exchange ratio used to determine the fraction of a share of
Inverness common stock to be received by Integ shareholders in connection with
the merger, rounded up to the nearest cent for options and rounded to the
nearest cent for warrants. By virtue of the merger, all Integ stock options
issued under Integ's 1990 Incentive and Stock Option Plan, 1991 Incentive and
Stock Option Plan, 1994 Long-Term Incentive and Stock Option Plan, as revised
and restated, and 1996 Directors' Stock Option Plan automatically will be deemed
vested and immediately exercisable.


    Inverness will use its best efforts to register with the SEC the shares of
Inverness common stock to be received upon exercise of the assumed options
within 10 business days after the effective time of the merger.

EMPLOYEE STOCK PURCHASE PLAN

    As of the date of approval of the merger agreement by Integ's shareholders,
Integ's 1997 Employee Stock Purchase Plan will be considered terminated. Each
participant will receive from Integ:

    - the maximum number of whole shares of Integ common stock that the
      participants' account will purchase, and


    - cash in the amount of any remaining balance in the participant's account.



    However, a participant may elect to receive the entire amount of his or her
credit balance in cash in accordance with the terms of the employee stock
purchase plan.


EFFECTIVE TIME OF THE MERGER

    The merger will be completed upon the filing of the articles of merger with
the Secretary of the State of Minnesota and the filing of the certificate of
merger with the Secretary of State of the State of Delaware. Integ and Inverness
believe these filings will occur at the same time as the closing, which, unless
the parties otherwise agree, will occur on the second business day immediately
following the day on which the last of the conditions to closing are fulfilled
or waived.

EXCHANGE OF INTEG STOCK CERTIFICATES FOR INVERNESS STOCK CERTIFICATES

    Promptly after the effective time of the merger, Boston EquiServe,
Inverness' transfer agent and exchange agent for the merger, will mail to you a
letter of transmittal and instructions for use in surrendering your Integ stock
certificates in exchange for Inverness stock certificates. When you deliver your
Integ stock certificates to the exchange agent along with a properly executed
letter of transmittal

                                       46
<PAGE>
and any other required documents, your Integ stock certificates will be
cancelled and you will receive Inverness stock certificates representing the
number of full shares of Inverness common stock, and cash in lieu of fractional
shares, to which you are entitled under the merger agreement. YOU SHOULD NOT
SUBMIT YOUR STOCK CERTIFICATES FOR EXCHANGE UNTIL YOU HAVE RECEIVED THE LETTER
OF TRANSMITTAL AND INSTRUCTIONS REFERRED TO ABOVE.

    You are not entitled to receive any dividends or other distributions on
Inverness common stock with a record date after the merger is completed until
you have surrendered your Integ stock certificates in exchange for Inverness
stock certificates. If there is any dividend or other distribution on Inverness
common stock with a record date after the merger and a payment date prior to the
date you surrender your Integ stock certificates in exchange for Inverness stock
certificates, you will receive the dividend with respect to the whole shares of
Inverness common stock issued to you promptly after they are issued. If there is
any dividend or other distribution on Inverness common stock with a record date
after the merger and a payment date after the date you surrender your Integ
stock certificates in exchange for Inverness stock certificates, you will
receive the dividend with respect to the whole shares of Inverness common stock
issued to you promptly after the payment date.

    Inverness will only issue an Inverness stock certificate or a check in lieu
of a fractional share in a name other than the name in which a surrendered Integ
stock certificate is registered if you present the exchange agent with all
documents required to show and effect the unrecorded transfer of ownership and
show that you paid any applicable stock transfer taxes.

For these purposes the obligations to use "best efforts" to obtain waivers,

    Integ has agreed, prior to the effective time of the merger, except as
specifically permitted by the merger agreement or with the consent of Inverness
and Terrier, to use its reasonable best efforts to conduct its operations
according to its usual, regular and ordinary course in substantially the same

        plan of Integ;

<PAGE>
     (2) enter into, adopt, amend or terminate any agreement, arrangement, plan
        or policy between Integ and one or more of its directors or officers; or

     (3) except for normal increases in the ordinary course of business

    - amend or waive any rights under Integ's Company Rights Agreement; or

    - enter into an agreement to take any of the foregoing actions.

    Integ has further agreed, among other things, that it will:

    - take all action necessary to convene a meeting of its shareholders as
      promptly as practicable to consider and vote upon the approval of the
      merger agreement and the transactions contemplated therein. Except as
      provided in the merger agreement, the proxy statement of Integ must
      contain the recommendation of the Integ board of directors that its
      shareholders approve the merger agreement and the transactions
      contemplated therein. Integ, including its board of directors, subject to
      and in accordance with applicable law, has agreed to use its reasonable
      best efforts to obtain such approval, including by timely mailing this
      proxy statement to its shareholders.

    Inverness has agreed, among other things, to:

    - at or prior to the effective time of the merger, fund the redemption of
      all outstanding shares of Integ's Series B preferred stock for cash
      consideration in accordance with the terms of the Integ's articles of
      incorporation;

    - promptly prepare and submit to the American Stock Exchange all reports,
      applications and other documents that may be necessary or desirable to

      be reserved for issuance at the effective time to be listed for trading on
      the American Stock Exchange; or

    - file the reports required to be filed by it under the Securities Exchange
      Act of 1934 and the rules and regulations adopted by the SEC thereunder,
      and Integ will take such further action as any affiliate, within the
      meaning of Rule 145 under the Securities Act of 1933, of Integ may
      reasonably request, all to the extent, if any, required from time to time
      to enable such affiliate to sell shares of Inverness common stock received
      by the affiliate in the merger without registration under the Securities
      Act of 1933 pursuant to (a) Rule 145(d)(1) or (b) any successor rule or
      regulation.

    The agreements related to the conduct of Integ and Inverness prior to the
closing of the merger are complicated and not easily summarized. You are urged
to carefully read the article in the merger agreement entitled "Covenants."

                                       51
<PAGE>
NO SOLICITATION OF TRANSACTIONS

    Until the merger is completed or the merger agreement is terminated, Integ
has agreed not to, and not to authorize or permit its officers, directors or
employees or professional representatives to:

    - solicit, initiate or encourage, including by way of furnishing non-public
      information, or take any other action to facilitate any inquiries or the
      making of any proposal that constitutes an acquisition proposal;

    - engage or participate in any discussion with, or provide any confidential
      information or data to, any person relating to any acquisition proposal;
      or

    - otherwise facilitate any effort to attempt to make or implement an
      acquisition proposal.

    Integ further agreed to cease and cause to be terminated any existing
activities, negotiations or discussions with any persons related to such
activities.

    Furthermore, Integ's board is not permitted to adversely withdraw or modify,
or propose to withdraw or modify, its approval or recommendation of the merger
or the merger agreement.

    For these purposes, an acquisition proposal is a proposed or actual:

    - merger, consolidation or similar transaction involving Integ;

    - sale, lease or other disposition, directly or indirectly, by merger,
      consolidation, share exchange or otherwise, of any assets of Integ
      representing 15% or more of the assets of Integ;

    - issue, sale or other disposition by Integ of, including by way of merger,
      consolidation, share exchange or any similar transaction, securities, or
      options, rights or warrants to purchase, or securities convertible into,
      such securities, representing 15% or more of the votes associated with the
      outstanding securities of Integ;

    - tender offer or exchange offer in which any person shall acquire
      beneficial ownership, as such term is defined in Rule 13d-3 under the
      Securities Exchange Act, or the right to acquire beneficial ownership, or
      any "group," as such term is defined under the Securities Exchange Act of
      1934, shall have been formed which beneficially owns or has the right to
      acquire beneficial ownership of, 15% or more of the outstanding shares of
      Integ common stock;

    - recapitalization, restructuring, liquidation, dissolution or other similar
      type of transaction with respect to Integ; or

    - transaction that is similar in form, substance or purpose to any of the
      foregoing transactions.

    This covenant does, however, expressly permit Integ to engage in discussions
or negotiations with a third party who makes an unsolicited bona fide written
acquisition proposal, or to approve or recommend such unsolicited acquisition
proposal, prior to the special meeting of Integ's shareholders if:

    - a majority of the disinterested directors of Integ determines, in good
      faith after consultation with its independent financial advisors that the
      competing proposal is more favorable to Integ's shareholders from a
      financial point of view than the transactions contemplated in the merger
      agreement;

    - the Integ board has determined in good faith, based on its consultation
      with experienced outside legal counsel that the proposal is a superior
      proposal based on these standards;

    - Integ's board has determined in good faith after consultation with its
      independent financial advisor that the third party is financially capable
      of completing the acquisition proposal and the acquisition proposal is
      likely to be consummated; and

                                       52
<PAGE>
    - a majority of the disinterested directors of Integ determines in good
      faith, after receiving advice from outside legal counsel, that the action
      is required for the board of directors to act in a manner consistent with
      its fiduciary duties under applicable law.

    In the event that Integ accepts a superior proposal, it will be obligated to
pay a termination fee of $2,000,000 plus expenses up to $2,000,000. Please refer
to the sections of this proxy statement and prospectus entitled "Termination"
and "Termination Fees and Expenses" on pages 56-57.

    Integ is not prohibited from taking and disclosing to Integ's shareholders a
position in conjunction with sections 14d-9 or 14e-2 of the Securities Exchange
Act of 1934 related to a tender or exchange offer.

    Integ has agreed to notify Inverness promptly if it receives any competing
proposal and the terms and conditions thereof, except that Integ is not required
to identify the party making the acquisition proposal.

OFFICERS AND DIRECTORS INDEMNIFICATION


    After the merger is completed, Inverness will preserve all rights to
indemnification existing as of October 3, 2000, the date of the merger
agreement, in favor of any director, officer, employee or agent of Integ for a
period of at least six years following the merger. Terrier will also indemnify
directors, officers, agents, fiduciaries and employees of Integ against
liabilities or claims arising before the merger is completed and as a result of
their positions at or due to the negotiating, execution or performance of the
merger agreement and the transactions contemplated therein. Integ will purchase
an extended reporting period endorsement to provide directors and officers with
liability insurance coverage for six years following the merger similar to the
coverage presently maintained by Integ.


ACCESS TO INFORMATION AND CONFIDENTIALITY

    Inverness and Integ have agreed to, and to cause each of their respective
subsidiaries, if any, and each of their respective subsidiaries' officers,
employees and agents to, afford to the other and to the officers, employees and
agents of the other complete access, except to the extent each other's access is
prohibited by the terms of a binding agreement between Integ and a third party,
at all reasonable times to such officers, employees, agents, properties, books,
records and contracts, and shall furnish to the other such financial, operating
and other data and information as the other may reasonably request. Furthermore,
prior to the effective time, Inverness has agreed to hold in confidence all such
information.

PUBLICITY

    Inverness and Integ have agreed to consult with each other before issuing
any press release or otherwise making any public statements with respect to the
merger agreement or any transaction contemplated thereby and not issue any press
release or make any public statement generally without the prior consent of the
other party, which consent will not be unreasonably withheld.

the merger by mutual written consent. Either Inverness and Terrier, on one hand,
or Integ, on the other hand, may terminate the merger agreement if:

    - any required approval of the Integ shareholders has not been obtained at
      the special meeting;

    - any governmental entity has issued an injunction taken or other action
      that permanently enjoins the merger (provided that prior to March 31, 2001
      Inverness, Terrier and Integ will use their best efforts to have any
      non-final injunction stayed or reversed);

    - the other party materially breaches any representation, warranty, covenant
      or agreement contained in the merger agreement, which breach cannot be
      cured within 15 business days of notice of the breach, except for those

      results of operations or financial condition of the breaching party; or

    - if the merger has not occurred by March 31, 2001, without a material
      breach by the terminating party of its obligations under the merger
      agreement.

    The merger agreement may be terminated by Integ if, prior to the special
meeting Integ concurrently enters into a definitive agreement with respect to a
superior proposal, provided that Integ:

    - provides Inverness and Terrier with five business days prior notice of the
      decision to terminate, which notice must include detail about the terms
      and conditions of the superior proposal, during which time Inverness may
      propose, and Integ must consider, any adjustment to the merger agreement;
      and

    - concurrently with the effectiveness of the termination, has paid to
      Inverness or its designee the termination fee described below in
      "--Termination Fees and Expenses."

    The merger agreement may be terminated by Inverness or Terrier if:

    - the Integ board does not make a recommendation of, or withdraws, amends,
      modifies or changes its approval or recommendation of, the merger
      agreement or the transactions contemplated thereby;

    - the Integ board fails to include its favorable recommendation regarding
      the merger in this proxy statement and prospectus;

        proposal;

     (6) Integ makes a proposal or announcement of its intention to enter into
        an agreement with respect to an acquisition proposal; or

     (7) Integ or its board resolves to do any of the foregoing.

    Furthermore, if either party terminates the merger agreement because:

    - the required approval of the Integ shareholders has not been obtained at
      the special meeting; or

    - the merger has not occurred by March 31, 2001, and the terminating party
      is not in material breach of its obligations; or

    - Inverness or Terrier terminates the merger agreement because Integ
      materially breaches any representation, warranty, covenant or agreement
      contained in the merger agreement;

    and, if prior to one year from such termination, Integ enters into an
acquisition proposal, with any other entities with some exceptions, or the Integ
board recommends or resolves to recommend to Integ shareholders approval or
acceptance of an acquisition proposal with any party, with some exceptions;

    then, Integ is required to pay Inverness a termination fee of $2,000,000.

    Additionally, if Inverness or Terrier terminates the merger agreement
because Integ materially breaches any representation, warranty, covenant or
agreement contained in the merger agreement, and this breach is caused by a
willful act, omission or other willful misconduct of Integ, then Integ is
required to reimburse Inverness and Terrier for their out-of-pocket costs and
expenses incurred in connection with the merger agreement and the transactions
contemplated thereby, up to a maximum of $2,000,000.

    Integ further agreed not to enter into any agreement relating to an
acquisition proposal within one year of termination of the merger agreement
without a provision requiring payment of the $2,000,000 termination fee.

    Except as otherwise specified in the merger agreement or agreed by the
parties, each party will pay all fees and expenses it incurs in the merger.

AMENDMENTS

    Inverness and Integ may amend the merger agreement at any time before or
after the necessary approval by the shareholders of Integ, but in any event
following authorization by the Integ board and the Inverness board. However,
after any required shareholder approval, no amendment will be made

                                       57
<PAGE>
that by law requires further approval by the shareholders without obtaining
their approval. The merger agreement was amended for technical reasons by the
parties to the agreement on October 16, 2000.

REVISED TRANSACTION

    Inverness and Terrier have retained the right to revise the method of
effecting the merger provided that:

    - any breach of the merger agreement by Integ or a failure by Integ to
      satisfy a condition of closing arising solely as a result of the revised
      method will not be considered a breach or failure to satisfy that
      condition to closing;

    - the merger will continue to qualify as a tax-free reorganization; and

    - the consideration to be received by Integ will not be altered, Integ will
      not incur additional costs and Integ will not be exposed to additional
      liability.

RELATED AGREEMENTS

                               INTEG INCORPORATED

    Integ Incorporated is a development stage medical technology company focused
on developing an innovative glucose monitoring product to enable people with
diabetes to manage their disease more effectively and conveniently. Integ has
focused its efforts on developing methods to sample interstitial fluid, the
clear fluid found between the cells throughout the body, and methods of
presenting this sample to various types of glucose measurement systems in an
integrated fashion. Integ has developed and broadly patented what it believes is
a unique technology to collect interstitial fluid samples. Using this
technology, it has conducted extensive research on interstitial fluid. With
Integ's advancements in interstitial fluid sampling technology and knowledge of
interstitial fluid, it hopes to improve diabetes self-management by eliminating
the need to draw blood for glucose monitoring. Integ believes that its
technology, when combined with commercially available glucose measurement
technology, will create a handheld glucose monitoring product for use by people
with diabetes that will be simpler to use and less messy than current alternate
site blood based test systems, and less painful than traditional fingerstick
devices. Integ believes that this product, which Integ refers to as the
LIFEGuide-TM- System, will allow people with diabetes to frequently self-monitor
their glucose levels without repeatedly enduring the pain and mess associated
with lancing their fingers to obtain a blood sample. Integ is a Minnesota
corporation and was incorporated in April 1990.

    Integ announced in April 1999 that it had formed an alliance and entered
into a development agreement with Amira Medical to jointly develop a new
generation of home glucose monitoring tests utilizing interstitial fluid. Upon
completion of the merger with Inverness, the alliance with Amira will be
terminated. The alliance called for products to be developed that combine
Integ's interstitial fluid collection technology with Amira's glucose
measurement technologies. The alliance contemplated both Integ and Amira
contributing resources to the development of these products, to be manufactured
by Integ and commercialized by Amira. Under the terms of the alliance, Integ's
responsibilities include:

    - the development of a method to sample interstitial fluid using its
      proprietary sampling technology;

    - designing and manufacturing a means to integrate its sampling technology
      with Amira's test strip technology; and

    - the manufacture of a packaged and sterile LIFEGuide-TM- Key, including
      Integ's interstitial fluid sampling technology incorporating Amira's test
      strip.

Under the alliance, Amira responsibilities include:

    - development and calibration of a sterilizable test strip;

    - test strip manufacturing and scale-up and bulk shipping system
      development;

    - defining test strip environmental and packaging requirements inputs for
      the LIFEGuide-TM- Key;

    - development of meter electronics, optics, calibration and software;

    - management of ongoing meter contract manufacturing;

                                       60
<PAGE>
    - filing and holding title to all regulatory submissions in its name in
      connection with the strategic alliance; and

    - labeling and packaging the LIFEGuide-TM- System for final sale and
      marketing, sales, distribution and customer service of the LIFEGuide-TM-
      System.


    As part of the alliance, Integ has the option, at a future date, to be
acquired by Amira, subject to certain conditions. Total consideration payable to
Integ's shareholders, optionholders, and warrantholders in connection with any
acquisition by Amira is $20,000,000 in cash and 2,000,000 shares of common stock
of Amira, subject to reduction in certain circumstances. The complete terms of
the agreement are available as an exhibit to the Integ Current Report on
Form 8-K filed with the SEC on April 9, 1999.


    Under the alliance, Integ and Amira established a joint product development
plan involving four product platform phases: feasibility, calibration, clinical
and commercial. Integ completed the feasibility phase of the plan, where it
demonstrated the ability to measure interstitial fluid glucose using the Amira
AtLast-TM- system in a non-integrated fashion, in September 1999. Integ
announced completion of the calibration phase in February 2000. On March 29,
2000 Integ announced that, based on discussions with Amira, it expected to do
additional development work on the LIFEGuide-TM- System before proceeding to
clinical trials. Integ has not established a new target date for entering
clinical trials.

INDUSTRY OVERVIEW

    It is estimated that there are as many as 120 million people with diabetes
worldwide, and nearly 16 million Americans are affected. Diabetes is a chronic
disease affecting overall health, which can lead to severe complications and
requires active disease management on a daily basis.

    The use of personal glucose monitors is a key factor in the management of
diabetes. Glucose levels are dynamic and vary throughout the day depending upon
food intake, insulin availability, exercise, stress and illness. People with
diabetes attempt to maintain their glucose levels within an acceptable range
through the use of insulin injections, oral glucose reducing agents called
hypoglycemic agents, diet, exercise or a combination of these activities. People
with diabetes often test their glucose levels at multiple times during the day,
including before eating meals and when their glucose levels are suspected to be
rising or falling faster than desired.

    Integ believes that sales of personal blood glucose monitoring products have
increased significantly in recent years due to technological innovations, the
development of retail distribution channels and increasing awareness of the
benefits of frequent glucose monitoring. Historically, consumers have selected
devices that offer the greatest ease of use while providing fast and accurate
blood glucose measurements, and technological innovators have tended to capture
significant market share rapidly.

EXISTING PERSONAL BLOOD GLUCOSE MONITORING SYSTEMS AND NEW ALTERNATIVE
  TECHNOLOGIES

    Most of the current commercially available glucose monitoring systems
involve obtaining a patient's blood sample in order to measure glucose. In
conventional glucose monitoring systems, blood samples are taken from the
fingertips because of the high concentration of capillaries at that site and
because the blood produced at the fingertip can most easily be applied directly
to the test strips used in such devices. The primary drawbacks to this approach
are the pain associated with lancing a fingertip to produce the sample and the
mess and inconvenience of handling blood.

    Most currently available personal blood glucose monitoring systems employ a
disposable test strip in conjunction with a battery-powered, handheld meter, and
a separate lancing device with its own disposable. These systems usually require
the user to:

    - assemble the lancing device with a disposable lancet;

                                       61
<PAGE>
    - determine the calibration code from the test strip package and adjust the
      meter as required to be properly calibrated to the test strip being used;

    - insert the test strip into the meter;

    - lance the finger or arm and form a drop of blood; and

    - apply the blood sample to the test strip and wait for the meter to display
      the results.

    The goal of most recent glucose monitoring research has been to develop an
accurate system to monitor glucose without the pain of a finger lance or the
need to handle blood. Most of this research falls into five categories:

    - non-invasive near-infrared spectroscopy;

    - reverse iontophoresis;

    - alternate site blood sampling techniques;

    - implantable sensors; and

    - interstitial fluid technologies.

    Non-invasive near-infrared spectroscopic technology generally attempts to
estimate glucose levels by measuring light absorption when an infrared light
signal is transmitted through or reflected off of a body part. Every chemical
entity that absorbs infrared energy has a characteristic waveband where that
absorption occurs. This absorption is proportional to its concentration. It is
this characteristic waveband that allows a chemical entity to be identified and
measured. No devices of this type have yet successfully demonstrated safety and
effectiveness to the FDA.

    Reverse iontophoretic technology uses electrical current to draw glucose
molecules out of the skin for measurement. Iontophoresis is a process by which
charged molecules are carried through intact skin by applying a small amount of
electrical current. Reversing that current can pull charged molecules from the
body; with those molecules comes fluid, and with that fluid comes uncharged
molecules like glucose. This fluid can be accumulated in a test chamber, in
which the glucose can be measured using traditional electrochemical means. At
this time, this technology is targeted toward continuous monitoring as a
supplement to finger-stick testing. One product of this type has been submitted
for FDA approval but not yet approved.

    A newer class of products continues to involve the measurement of glucose in
blood but attempts to reduce pain by minimizing the volume of blood required and
broadening the sites available for sampling. The products currently available in
this category involve the same steps as current blood glucose systems, but allow
the user to lance their forearm or thigh rather than the fingertip. Three
products of this type are currently on the market. A blood sample is still
required, as is the time and mess associated with getting that sample. Many
people with diabetes are uncomfortable with routinely testing glucose levels in
the presence of others because of the negative perceptions associated with
visible blood. One company has discussed plans for a product that uses blood but
eliminates the separate handling step and has demonstrated models at recent
industry conferences.

    Implantable sensors are targeted toward continuous monitoring of a patient's
glucose level. They generally involve implanting a three-day sensor in the
patient, which is attached through electrical leads to a monitoring device that
is worn externally. One such product has been approved by the FDA but its
intended use is limited to identifying trends for the physician retrospectively.
The patients must still use a blood glucose meter for monitoring their glucose
levels, taking therapeutic action, and calibrating the implanted sensor.

    Interstitial fluid technology involves obtaining a sample of interstitial
fluid from the skin. Integ and other companies are currently pursuing
interstitial fluid technology. In addition to Integ's specific

                                       62
<PAGE>
approach for collecting and measuring interstitial fluid, examples of other
approaches include creating an opening in the skin using a laser or other means,
drawing interstitial fluid through the opening and electrochemically measuring
the sample. Another example includes chemically enhancing the skin's
permeability and allowing interstitial fluid to flow into a patch for subsequent
colorimetric measurement.

THE INTEG SOLUTION

    Integ is developing the LIFEGuide-TM- System to allow people with diabetes
to easily and accurately measure their glucose levels without the need for a
finger lance or the need to handle blood. The LIFEGuide-TM- System will consist
of two main components: Integ's proprietary interstitial fluid sampling
technology to collect a sample of interstitial fluid and a measuring technology
to measure the level of glucose present in the interstitial fluid sample. Under
the strategic alliance, the system being developed has focused on combining the
measurement technology components of the Amira AtLast-TM- blood glucose system,
both meter and test strip, with Integ's interstitial fluid sample extraction
technology of the LIFEGuide-TM- System. If the merger is completed, the system
will be developed by combining the measurement technology components of
Inverness with Integ's fluid sample extraction technology.

    Interstitial fluid is an extracellular fluid that is prevalent throughout
the body and skin. Interstitial fluid is the means through which proteins and
nutrients, including glucose, pass between capillaries and cells. The LIFEGuide
System extracts an interstitial fluid sample from the dermis, or external
surface, of the skin. The sample is comprised primarily of interstitial fluid,
but may also contain some intracellular fluid and red blood cells. Samples
extracted with the LIFEGuide-TM- method are very consistent. A clinical study
that compared the glucose levels in multiple samples taken from single patients
showed very tight precision, measured as coefficients of variation that averaged
3-5% for most subjects. The results of this study were published in CLINICAL
CHEMISTRY and were presented at the 1999 Oak Ridge Conference of the American
Association of Clinical Chemistry.

    The LIFEGuide-TM- System is based on research indicating that interstitial
fluid glucose levels correlate closely with blood glucose levels. The
concentration of glucose in interstitial fluid is very similar to the
concentration of glucose in blood. However, it does take a little time for the
glucose to travel from blood into the interstitial fluid. This time is called
lag time. The magnitude of the lag varies somewhat depending on the study and
the collection or measurement techniques applied. In published literature, lag
times of 10 to 20 minutes are typically reported, with a few studies claiming as
little as no time lag, or as much as 45 minutes. Much research has been done
with microdialysis collection of interstitial fluid from the subcutaneous layer
of the skin. A review of the scientific literature shows that many researchers
see a good correlation between interstitial fluid glucose and blood glucose with
a short time lag when employing the microdialysis technique. Although this
sample collection method differs from the method employed by LIFEGuide-TM-, the
results are instructive for gaining a general understanding of the relationship
between interstitial fluid and blood glucose levels, and the results are similar
to internal studies conducted with LIFEGuide-TM-. Under the strategic alliance,
Integ has been conducting studies to further understand lag time in various
patient populations, particularly as glucose is rapidly falling.

THE LIFEGUIDE-TM- SYSTEM

    Integ's LIFEGuide-TM- System will be comprised of (1) the LIFEGuide-TM-
Meter, a reusable glucose measuring device, and (2) the LIFEGuide-TM- Key, a
single-use, disposable interstitial fluid sample collection device.

                                       63
<PAGE>
    The proposed LIFEGuide-TM- System will be a simple-to-use, interstitial
fluid-based glucose testing system intended to be used by people with diabetes
in a similar manner to traditional blood glucose test systems. The system
extracts a small sample of interstitial fluid from the dermal layer of the skin
on the forearm and measures glucose in the sample with an integrated, one-piece,
disposable, named a "key." The LIFEGuide-TM- System will be calibrated to give
plasma-equivalent glucose results similar to those given by many blood glucose
meters. This is also the method used by laboratories.

    The single-use, disposable LIFEGuide-TM- Key is designed to be easily
handled by the user and inserted into the LIFEGuide-TM- Meter. The design of
this key will allow for the capture of the required interstitial fluid sample
and the retention of the sample during the measurement and disposal process. The
key contains a very small needle that is used to extract a small sample of
interstitial fluid and present it in a very controlled fashion to the
measurement system. No user intervention is required to get the sample to the
measurement zone of the test strip. The LIFEGuide-TM- Key will be packaged in
individual sterile packages.

    Integ believes the LIFEGuide-TM- System should offer advantages over
commercially available personal blood glucose monitoring systems and products
under development, including the following:

    - Sampling Flexibility--The LIFEGuide-TM- System is designed to be used on
      skin almost anywhere on the body, staying away from areas, such as the
      fingertips, where blood capillaries and nerve endings are concentrated.
      Initial company efforts are focused on forearm testing.

    - Bloodless Approach--The LIFEGuide-TM- System is designed to allow for the
      accurate measurement of glucose levels without drawing blood. This
      approach eliminates the mess and inconvenience of handling a blood sample
      and the negative perceptions associated with visible blood.

    - Ease of Use--Integ's proposed LIFEGuide-TM- System will eliminate some of
      the steps required by commercially available personal blood glucose
      monitoring systems. With currently available systems, the user requires
      two disposables, a lancet and a separate test strip. After lancing the
      finger or alternate site, a drop of blood must be formed and directed to a
      target zone on a strip. The LIFEGuide-TM- System requires only one
      disposable, the LIFEGuide-TM- Key. The sampling procedure of the proposed
      LIFEGuide-TM- System has been reduced to simply inserting the key into the
      meter, holding the device against an area of exposed skin until an
      adequate sample has been obtained and waiting briefly for a displayed
      result. Integ believes this may represent the simplest to use system on
      the market and may also reduce the possibility of user errors affecting
      readings.

    - User Safety--The user's safety is ensured in that each single-use key is
      sterilized and packaged individually. The meter will not allow a test to
      begin with a used sampler, eliminating the possibility that the sampling
      device can be used more than once. Also, because the sample is
      automatically captured in the key, there are fewer items requiring
      disposal.

    - Factory Calibration--Exactly like other commercial blood glucose makers,
      the LIFEGuide-TM- System can be factory calibrated with a lot-specific
      code. Other interstitial fluid systems which have been shown to the FDA
      require at least one fingerstick blood glucose measurement daily for
      calibration.

    Because of these potential advantages, Integ believes that the proposed
LIFEGuide-TM- System may facilitate greater compliance with the recommendations
of the American Diabetes Association. However, it has not yet finalized the
development of its LIFEGuide-TM- System, and Integ cannot be sure that it will
be able to successfully develop a commercially acceptable product.

RESEARCH AND DEVELOPMENT

    Under the terms of its alliance with Amira, Integ is responsible for
research and development of interstitial fluid sampling technology, design and
manufacturing development of a means to integrate the interstitial fluid
sampling technology with a Amira's test strips and designing the interface
between Amira's metering system and Integ's interstitial fluid sampling
technology.

    Since inception and through September 30, 2000, Integ has incurred
approximately $25.2 million in research and development expenses. Integ spent
approximately $2.3 million, $5.5 million and $5.3 million during fiscal years
1999, 1998 and 1997, respectively, on research and development.

    Once the alliance with Amira was formed, 1999 research and development
activities were focused on the integration of Integ's interstitial fluid
collection technology with Amira's glucose measurement technology. By fourth
quarter of 1999 Integ had designed, built, and tested a new LIFEGuide-TM-
handheld prototype system that reliably collected a one microliter sample of
interstitial fluid and automatically delivered it directly to a test strip for
glucose measurement. Technical accomplishments during the year that were inputs
to this system design included:

    - developing a consistently performing calibration of Integ interstitial
      fluid to fingerstick blood reference values;

    - further analytical work on the relationship between blood and Integ
      interstitial fluid;

    - development of test strip chemistries that may be sterilized along with
      the tiny needle so that a single piece disposable design could be
      implemented; and

    - unique microfluidics concepts for handling small interstitial fluid sample
      volumes.

    This integrated prototype LIFEGuide-TM- System was then tested in a series
of internal trials on people with diabetes. These trials provided user feedback,
gathered data for finalizing factory calibration methods, verified interstitial
fluid collection proficiency, and assessed clinical accuracy and precision
performance. While not designed specifically as market research, the trials
indicated what user related improvements and features would be desirable in the
commercial product.

    Integ's success is highly dependent upon its ability to combine its sampling
technology with the measurement technology of a third party and the successful
development, commercialization and market acceptance of the LIFEGuide-TM-
System, the development of which is ongoing and the complete efficacy of which
has not yet been demonstrated.

CLINICAL TESTING

    Under the terms of the alliance, Amira is responsible for filing and holding
title to all regulatory submissions in its name in connection with the jointly
developed LIFEGuide System.

    Integ conducted a series of method comparison studies in the third and
fourth quarter of 1999 on handheld prototype versions of the LIFEGuide-TM-
System using the Amira measurement technology. This data was used to complete
the calibration of the clinical handheld LIFEGuide-TM- System.

    Also in 1999, Integ made presentations of two posters at the 1999 American
Association of Clinical Chemistry Oak Ridge Conference. One of the presentations
included a talk. One poster discussed the results of an internal clinical study
that demonstrated the tight correlation of glucose values gathered from multiple
sites on the forearm. The second described performance of our internal
electrochemical lab system.

    Integ submitted clinical protocols to the FDA for review in late January of
2000. A meeting was held with the FDA on March 21, 2000 to review these
protocols. The FDA has requested modifications to the protocols submitted and
advised Integ that a Premarket Approval may be required. Integ has not

                                       65
<PAGE>
yet determined whether it will pursue a 510(k) or a Premarket Approval. These
options are discussed in more detail below, under the heading "--Government
Regulation."

    Since that time, Integ has completed discussions with Amira. In the event
the merger with Inverness is not completed, Amira will be funding further
research and development of the product. Based on these discussions, Integ
expects to conduct additional research and pre-clinical trials to confirm the
protocol additions suggested by the FDA and to verify system performance and
intended use. Integ and Amira also expect to evaluate additional product changes
to improve user features before proceeding with clinical trials. As a result,
clinical trials have been delayed.

MANUFACTURING

    Under the terms of the alliance with Amira, Integ is responsible for
manufacturing the LIFEGuide-TM- Keys consisting of a packaged and sterile
interstitial fluid disposable sampler, which incorporates Amira's test strip.
Integ anticipates that it will assemble the keys at its facilities from
components obtained from outside suppliers. In manufacturing the keys, Integ
will use assembly, testing and packaging equipment employing well-known
processes similar to those used for other high speed assembly applications.

    Under the terms of the alliance, Amira is responsible for development of the
LIFEGuide-TM- Meter electronics, optics, calibration and software and management
of meter contract manufacturing.

SALES AND MARKETING

    Under the alliance, Amira is responsible for marketing, sales, distribution
and customer service with respect to the LIFEGuide-TM- System. Integ is required
to market and sell the LIFEGuide-TM- System through Amira. Under the strategic
alliance, Integ receives a fixed percentage of profit over its costs up to a
certain cap in producing the LIFEGuide-TM- Key, which is not based upon the
LIFEGuide-TM- System selling price.

    Amira is currently in the process of building its sales, marketing and
distribution capabilities. Many of Integ's potential competitors have already
entered into distribution and marketing agreements with major marketing
partners.

INTELLECTUAL PROPERTY

    Integ believes that it is important for it to obtain patent protection for
its proposed products and processes, to preserve its trade secrets and to
operate without infringing the proprietary rights of third parties. Integ has
implemented a strategy of pursuing patent applications to provide both design
freedom and protection from competitors. This strategy includes evaluating and
seeking patent protection covering each of the areas of invention embodied in,
and the specific features of its LIFEGuide-TM- System as well as having the
breadth to cover features of competing alternatives. Integ has three issued
United States patents relating to its interstitial fluid sampling technology and
the method of drawing an interstitial fluid sample from the outer layers of the
skin, as well as two related US patents. Integ also has numerous other issued US
patents, and US patent applications covering various other aspects of its
technology. Integ has several US patents covering the design features of its
LIFEGuide-TM- Key. In addition to its US patent protection, Integ regularly
seeks corresponding patent coverage in other markets throughout the world. For
example, Integ has issued patent protection in numerous countries, including
member states of the European Union for its interstitial fluid sampling
technology.

    Integ also relies upon trade secrets and proprietary know-how in its
manufacturing processes. It requires each of its employees, consultants,
advisors and certain of its vendors to execute a confidentiality agreement upon
the commencement of their relationship with Integ.

                                       66
<PAGE>
    There has been substantial litigation regarding patent and other
intellectual property rights in the medical device industry. Integ is not
currently a party to any patent or other litigation, and it routinely monitors
patent issuance by others in its industry.

    Pursuant to the terms of the alliance and upon the completion of the merger
with Inverness, Integ will grant Amira two licenses for use in the field of
glucose monitoring using Integ's interstitial fluid sampling technology. The
first license will be a perpetual, transferable, co-exclusive and non-terminable
license, including the right to sublicense, to certain intellectual property
patents and know-how of Integ existing prior to April 2, 1999 that is useful for
glucose monitoring using interstitial fluid samples. This license will give
Amira the right to make, import, use, offer for sale and sell products
incorporating the technology covered by the license. The second license will be
an exclusive, perpetual, transferable and non-terminable license, including the
right to sublicense, to certain intellectual property of Integ developed after
April 2, 1999 that is useful for glucose monitoring using interstitial fluid
samples. This license will give Amira the right to make, have made, import, have
imported, use, offer for sale and sell products which incorporate the technology
by the license. These licenses do not cover Integ's infared technology.

COMPETITION

    The glucose monitoring industry is characterized by intense competition and
is currently dominated by several companies with established products and
distribution channels. There are currently four significant competitors in the
worldwide blood glucose monitoring market: LifeScan, Inc., a subsidiary of
Johnson & Johnson, Inc.; Roche Diagnostics; Bayer Diagnostics, a division of
Bayer AG; and Medisense, Inc., a subsidiary of Abbott Laboratories.

    Companies in the glucose monitoring market compete on the basis of
innovative technology, ease of use, price, product reliability and acceptance by
consumers and healthcare professionals. Price competition for the placement of
monitors in the glucose monitoring market is intense and involves marketing
tactics such as rebates, trade-in offers and volume purchase incentive programs.
Pursuant to the strategic allowance, if Amira is not able to offer the
LIFEGuide-TM- System at a competitive price, Integ will not be required to
supply as many LIFEGuide-TM- Keys to Amira, and may not be able to reach
profitability.

    A number of entities are conducting research on possible non-invasive and
minimally invasive methods of determining glucose levels. Specific information
regarding the precise progress of these companies with respect to these
alternative technologies has not generally been made public. Using Inverness'
low volume FastTAKE product, LifeScan has introduced an alternate sampling site
blood product. ThereSense has also launched such a device, theirs requiring only
0.3 mircroliters of blood, the smallest available. Also, Abbott is planning to
offer an integrated alternate site blood glucose test system in the near future.
These companies' products may also affect the success of the LIFEGuide-TM-
System.

GOVERNMENT REGULATION

    Government regulation in the United States and other countries is a
significant factor in the development of the LIFEGuide-TM- System. The
LIFEGuide-TM- System will be regulated by the FDA under a number of federal
statutes including the Federal Food, Drug and Cosmetic Act, the Safe Medical
Devices Act of 1990, the FDA Modernization Act of 1997, and other associated
regulations governing the development, testing, manufacturing, labeling,
marketing and distribution of medical devices as well as the reporting of
certain information regarding their safety. Sales of the LIFEGuide-TM- System
outside the United States will also be subject to comparable foreign regulatory
requirements.

    FDA permission must be received to distribute a new medical device in the
United States and can be obtained in one of two ways. If a new or significantly
modified device is "substantially equivalent" to

                                       67
<PAGE>
an existing legally marketed device, the new device can be commercially
introduced after filing a 510(k) premarket notification with the FDA and the
subsequent issuance by the FDA of an order permitting commercial distribution.
Changes to existing devices that do not significantly affect safety of
effectiveness of the device may be made without an additional 510(k)
notification.

    The second path to market in the United States involves a more comprehensive
approval process known as a Premarket Approval. Premarket Approval applies to
new medical devices that are not substantially equivalent to a currently
marketed device. First, in a Premarket Approval application, Integ must conduct
clinical trials in accordance with testing protocols approved by an
Institutional Review Board for the participating research institution and the
investigational device exemption regulations promulgated by the FDA. Second,
Integ must submit a Premarket Approval application that contains the clinical
trial results, and other information required under the Food, Drug and Cosmetic
Act such as a full description of the device and its components, a full
description of the methods, facilities and controls used for manufacturing and
examples of proposed labeling. Finally, the manufacturing site(s) for the
medical device subject to the Premarket Approval process must operate under Good
Manufacturing Practices and pass an FDA Pre-Approval Inspection before the
product is approved.

    A meeting was held with the FDA on March 21, 2000 in which the FDA advised
Integ that a Premarket Approval may be required for the LIFEGuide-TM- System.
Integ has not yet determined whether it will pursue a 510(k) or a Premarket
Approval. The FDA has granted Integ expedited review of its LIFEGuide-TM- System
application in either 510(k) or Premarket Approval form. Expedited review may
shorten the time between submission of clinical trial data and approval from the
FDA to market the LIFEGuide-TM- System. However, the time period to obtain FDA
approval may be longer due to unfamiliarity with interstitial fluid.

EMPLOYEES

    As of September 30, 2000, Integ had a total of 31 full-time employees and
one part-time employee. Integ also employed 5 persons on a temporary or contract
basis, both full and part-time. Of the total work force, 14 persons were engaged
in research and development activities, 15 persons in manufacturing development
and 8 persons in administration. None of Integ's employees is covered by a
collective bargaining agreement. Integ believes that it maintains good relations
with its employees.

REAL PROPERTY

    Integ currently leases approximately 38,000 square feet of space at 2800
Patton Road, St. Paul, Minnesota. The lease expires on September 30, 2005. Integ
believes its facilities will be adequate for its needs through completion of the
development of the LIFEGuide System. Integ is already subleasing a portion of
the property and, by year end, will be subleasing more than half of this
property.

LITIGATION

    Integ is not a party to any legal proceedings.

                  INTEG'S MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

GENERAL

    From inception through September 30, 2000, Integ has incurred losses
totaling $53.5 million, consisting of $25.2 million of research and development
expenses, $10.5 million of manufacturing development expenses, and
$17.8 million of general and administrative and other expenses, net of interest
income. Integ's activities have consisted primarily of research and product
development, product design, development of the manufacturing equipment and
processes and marketing strategies needed for the introduction of the
LIFEGuide-TM- System. Integ has generated no revenue and has sustained
significant operating losses each year since inception. Integ expects such
losses to continue for the next several years.

    On October 4, 2000, Inverness and Integ announced that they had signed a
definitive agreement to merge Integ into a subsidiary of Inverness. In
connection with the merger agreement between Inverness and Integ, Inverness and
Integ entered into a loan agreement pursuant to which Inverness agreed to
provide funding of the operational expenses of Integ in the event that an event
of default under Integ's current funding arrangement has occurred, and is
continuing, and certain other conditions have been met.

    Integ announced in April 1999 that it had formed an alliance with Amira
Medical to jointly develop a new generation of home glucose monitoring tests
using interstitial fluid, or ISF. If the merger with Inverness is completed, the
alliance with Amira will be terminated. Under the terms of the alliance, Integ
is responsible for the development of a method to sample ISF using its
proprietary sampling technology, designing and manufacturing development of a
means to integrate Integ's sampling technology with Amira's test strip
technology, and manufacture of a packaged and sterile LIFEGuide-TM- Key,
including Integ's ISF sampling technology incorporating Amira's test strip. As
part of the alliance agreement, Integ has the option at a future date, to merge
with a subsidiary of Amira, subject to certain conditions. Total consideration
payable to Integ's shareholders, optionholders and warrantholders in connection
with any merger with Amira is $20 million in cash and 2,000,000 shares of common
stock of Amira, subject to reduction in certain circumstances.

    In January 2000, Integ established a budget for the year 2000 in support of
the joint development plan, which took into account the contributions that Amira
is making toward completion of LIFEGuide product development. On February 15,
2000, Integ entered into a preferred stock agreement with Amira which is
intended to provide up to $5.6 million in funding to Integ for the continued
development of the LIFEGuide-TM- System through the year 2000. Since
April 2000, Integ has been dependent upon sales of Series B preferred stock to
Amira to meet its operating expenses. Through September 30, 2000, Integ had
raised $3.1 million through the sale of 1,771,236 shares of Series B preferred
stock.

    On March 29, 2000 Integ announced that, based on discussions with Amira
Medical, it expected to do additional development work on the LIFEGuide-TM-
System before proceeding to clinical trials. Integ has not established a new
target date for entering clinical trials.

    Integ is developing the LIFEGuide-TM- System, a handheld glucose monitoring
product for use by people with diabetes. The LIFEGuide System will allow people
with diabetes to frequently self-monitor their glucose levels without repeatedly
enduring the pain and mess associated with lancing their fingers to obtain a
blood sample. Frequent monitoring may allow people with diabetes to manage their
disease more effectively and conveniently.

COMPARISON OF THE NINE MONTHS ENDED SEPTEMBER 30, 2000 AND 1999

    GENERAL.  Integ's net loss totaled $4.2 million for the nine months ended
September 30, 2000, as compared to $6.2 million for nine months ended
September 30, 1999. Integ expects net losses to continue for the next several
years.

    In conjunction with the alliance formed with Amira in April 1999, Integ
began cross-charging Amira for certain expenses related to the joint development
of the LIFEGuide-TM- System. In April 2000, Integ began funding its operations
through sales of Series B preferred stock to Amira and discontinued
cross-charging expenses to Amira. These cross-charges are described in our
analysis as "allocated expenses to Amira" and had the effect of reducing Integ's
operating expenses.

    Until her permanent appointment as President and CEO of Integ, Ms. Critzer
was accounted for in Manufacturing Development as she continued in her role as
Vice-president--Operations as well as Interim President and CEO. Since her
permanent appointment as President and CEO in April 1999, Ms. Critzer has been
accounted for in General and Administrative.

    RESEARCH AND DEVELOPMENT EXPENSES.  Research and development expenses
decreased to $1,289,000 during the nine months ended September 30, 2000 from
$1,828,000 for the nine months ended September 30, 1999. This decrease was
primarily attributable to decreased compensation expense of $147,000,
depreciation expense of $93,000, consulting fees of $216,000, contract fees of
$67,000, prototype expense of $68,000 and the allocation of expenses to Amira of
$17,000. These decreases were offset by increased patent related legal fees of
$20,000 and an increase in other expenses of $49,000.

    MANUFACTURING DEVELOPMENT EXPENSES.  For the nine months ended
September 30, 2000, manufacturing development expenses decreased to $1,425,000
from $1,495,000 during the nine months ended September 30, 1999. This decrease
was primarily attributable to decreased compensation expense of $121,000,
depreciation expense of $89,000 and prototype and prototype tooling expenses of
$12,000. These decreases were partially offset by increased contract fees of
$93,000, a reduction in the allocation of expenses to Amira of $22,000,
increased travel expenses of $19,000 and other expenses of $18,000.

    GENERAL AND ADMINISTRATIVE EXPENSES.  In accordance with the terms of the
alliance with Amira, Integ no longer incurs expenses categorized previously as
clinical and regulatory and sales and marketing. For presentation purposes,
prior period expenses have been reclassified as general and administrative. For
the nine months ended September 30, 2000, general and administrative expenses
decreased to $1,250,000 from $2,610,000 during the nine months ended
September 30, 1999. The decrease was primarily attributable to decreased
consulting fees of $1,075,000, insurance expense of $63,000, the allocation of
certain facility expenses to sub-lease tenant and Amira of $193,000, decreased
depreciation expense of $133,000, increased facility allocations to other
departments of $38,000, decreased Medical Advisory Board (MAB) expenses of
$21,000 and a decrease in other expenses of $59,000. The decrease was partially
offset by increased compensation expenses of $190,000, software expense of
$18,000 and printed supply expense of $14,000.

    INTEREST INCOME.  For the nine months ended September 30, 2000, interest
income decreased to $82,000 from $290,000 for the nine months ended
September 30, 1999. The decreases resulted from lower average balances of cash
and cash equivalents.

    INTEREST EXPENSE.  For the nine months ended September 30, 2000, interest
expense decreased to $305,000 from $532,000 during the nine months ended
September 30, 1999. The decrease in interest expense is attributable to payments
made on long-term debt and capital leases. On September 30, 2000 Integ's long
term liabilities, including current portions, were $1,635,000 as compared to
$3,067,000 on September 30, 1999.

                                       72
<PAGE>
    OTHER INCOME.  For the nine months ended September 30, 2000, other income
increased to $33,000 from an expense of $1,000 for the nine months ended
September 30, 1999. The increases are primarily attributable to gains from the
sale of excess equipment.

YEAR ENDED DECEMBER 31, 1999 COMPARED TO YEARS ENDED DECEMBER 31, 1998 AND 1997

    GENERAL.  Integ's net loss totaled $7.8 million during 1999 from
$11.1 million during 1998 and $11.6 million during 1997. Integ expects net
losses to continue for the next several years.

    RESEARCH AND DEVELOPMENT EXPENSES.  Research and development expenses
decreased to $2.3 million during 1999 from $5.5 million in 1998 and
$5.3 million from 1997. The decrease in research and development expense in 1999
was primarily due to $628,000 of decreased staffing costs, $665,000 of decreased
allocated pilot plant costs, $960,000 of decreased contractor and consulting
expenses, $376,000 of decreased prototype expense, the allocation of $226,000 of
expenses to Amira, a decrease of $188,000 in severance expense, a decrease of
$75,000 in depreciation expense and the decrease of other expenses totaling
$120,000 which were partially offset by increased legal expenses in the amount
of $56,000, allocated facility expenses in the amount of $46,000 and increased
travel expenses in the amount of $17,000. The increase in research and
development expense in 1998 when compared to 1997 is primarily attributable to a
$665,000 increase in the amount of pilot plant costs allocated to research and
development and a one-time $188,000 charge for the workforce reduction, which
were partially offset by $220,000 in decreased staffing costs, $346,000 in
decreased prototype expenses, $107,000 in decreased employee relocation costs,
and $60,000 in decreased lab supply expenses.

    MANUFACTURING DEVELOPMENT EXPENSES.  Manufacturing development expenses
decreased to $1.9 million during 1999 from $2.2 million in 1997 and
$2.5 million in 1997. The decrease in manufacturing development expenses during
1999 is primarily attributable to $132,000 in decreased staffing costs, $398,000
in decreased prototype expenses, the allocation of $279,000 of expenses to
Amira, $62,000 of decreased depreciation expenses, a decrease of $31,000 in
employee training expenses, a decrease of $39,000 in Travel, allocated facility
expenses of $38,000 and a $85,000 decrease in other expenses. These decreases
were partially offset by an increase of $665,000 in allocated pilot plant costs
to research and development and an increase of $99,000 in prototype tooling/test
fixtures. The decrease in manufacturing development expenses during 1998 is
primarily attributable to $208,000 of decreased staffing costs, the allocation
of $665,000 of pilot plant costs to research and development and a decrease of
$108,000 in prototype tooling expenses, a decrease of $93,000 in travel expenses
and a $66,000 decrease in the occupancy allocation, which were partially offset
by a $347,000 increase in depreciation expense, a $364,000 increase in samples
and prototype expenses and a one-time charge of $78,000 for workforce reduction.

    GENERAL AND ADMINISTRATIVE EXPENSES.  In accordance with the terms of the
strategic alliance with Amira, Integ no longer incurs expenses categorized
previously as clinical and regulatory and sales and marketing. For presentation
purposes, these expenses have been reclassified as general and administrative.
General and administrative expenses increased to $3.3 million during 1999 from
$3.2 million in 1998 and $4.6 million in 1997. The increase in general and
administrative expenses in 1999 is primarily attributable to a $1.1 million
increase in consulting expenses and a one-time $384,000 write-off due to
obsolescence of capital equipment. This was partially offset by a $1.1 million
decrease in staffing costs, a $103,000 decrease in travel, a decrease of
$136,000 in facility allocations to Amira and sub-lessee and a decrease of
$45,000 in miscellaneous expenses. The decrease in general and administrative
expenses in 1998 is primarily attributable to $482,000 of decreased staffing
costs and a special charge in 1997 for the resignation of Integ's President and
Chief Executive Officer effective in 1998 in the amount of $654,000, which were
partially offset by a $100,000 increase in legal and audit expenses, a $51,000
increase in recruitment expenses as well as the $28,000 one-time charge for
workforce reduction. The decrease in 1998 is also due to, what were previously
classified as clinical and

                                       73
<PAGE>
regulatory expenses, $133,000 of decreased staffing costs, $55,000 of decreased
recruitment costs, $33,000 of decreased travel costs, $28,000 of decreased
clinical studies expenses and $9,000 of decreased consulting expenses, which
were partially offset by the one-time $222,000 charge for workforce reduction.
The decrease in 1998 is also due to, what were previously classified as sales
and marketing expenses, $297,000 of decreased staffing costs, $97,000 of
decreased advertising and promotion expenses, $55,000 of decreased website
development expense, $33,000 of decreased consulting expenses, $35,000 of
decreased product development expenses and $17,000 of decreased travel expenses,
which were partially offset by a $173,000 one-time charge for the workforce
reduction.

    INTEREST INCOME.  Interest income decreased to $342,000 during 1999 from
$890,000 in 1998 and $1.6 million during 1997. The decrease in 1999 and 1998 is
a direct result of lower average balances of cash and cash equivalents.

    INTEREST EXPENSE.  Interest expense decreased to $682,000 during 1999
compared to $1.2 million in 1998 and $684,000 in 1997. The decrease in interest
expense in 1999 is attributable to payments made on long-term debt and capital
leases. The increase in interest expense during 1998 is attributable to
increased borrowings under the equipment loan agreement.

    OTHER INCOME (EXPENSE).  Other expense totaled $1,000 in 1999. Other income
totaled $98,000 in 1998, which primarily consisted of a $26,000 receivable
written off in a prior year which was paid in full and $66,000 received from the
state of Minnesota for a sales tax refund claim filed for prior years.

LIQUIDITY AND CAPITAL RESOURCES

    Integ's operations since inception have been funded by net proceeds from the
sale of common and preferred stock totaling approximately $55 million and
proceeds from borrowings under an equipment

                                       74
<PAGE>
loan agreement totaling $5.5 million. As of September 30, 2000 Integ had cash
and cash equivalents of $1.6 million and working capital of $100,000.

    The equipment loan agreement contains covenants that place restrictions on
sales of assets, transactions with affiliates, creation of additional debt, and
other customary covenants. Borrowings under the equipment loan agreement are
collateralized by a large part Integ's assets.

    On February 15, 2000, Integ entered into a preferred stock agreement with
Amira which is intended to provide up to $5.6 million in funding to Integ for
the continued development of the LIFEGuide System through the year 2000. Sales
of preferred stock to Amira only occur after Integ's cash balance has declined
to $1.5 million and Integ will then only sell preferred stock to Amira from time
to time in amounts sufficient for it to meet its expenses incurred in connection
with Integ's 2000 budget. Since April 2000, Integ has been dependent upon sales
of preferred stock to Amira to meet its operating expenses. As of September 30,
2000, Integ had raised a total of $3.1 million through the sale of 1,771,236
shares of Series B preferred stock. Integ believes that its cash and proceeds
from sales of Series B preferred stock will be sufficient to fund operations
through the first quarter of 2001. Under the terms of the Series B Preferred
Stock Agreement, upon closing of the merger with Inverness, Integ will be
required to redeem all outstanding shares of Series B preferred stock at a price
equal to the total purchase price paid for the outstanding shares of Series B
preferred stock plus a 10% premium, payable either in cash or shares of common
stock of Integ, at Integ's option. Under the terms of the merger agreement with
Inverness, Integ agreed to redeem the shares of Series B preferred stock for
cash, and Inverness agreed to fund the redemption of outstanding shares of
Series B preferred stock.

    In connection with the merger agreement between Inverness and Integ,
Inverness and Integ entered into a loan agreement pursuant to which Inverness
agreed to provide funding of the operational expenses of Integ in the event that
Integ's an event of default under current funding arrangement has occurred and
is continuing and certain other conditions have been met.

    As part of the alliance with Amira, Integ agreed that it would not take any
actions outside the ordinary course of business which would result in a
liability or an obligation to make payments, and would not issue any debt or
debt securities without Amira's consent, and that the amount of any of these
types of liabilities would be deducted from the consideration payable by Amira
in connection with the merger of Integ with a subsidiary of Amira. Integ also
agreed that it would not incur any liabilities or obligations to make payments
in excess of $1,000,000 in the ordinary course of business without Amira's
consent. Integ cannot predict whether these agreements will adversely affect its
ability to meet its future liquidity and capital requirements.

    If the merger is not consummated, Integ's future liquidity and capital
requirements will depend on numerous factors, including when or if the
performance of the LIFEGuide System meets the required performance
specifications, whether the merger with Inverness is completed, the ability of
Integ to successfully maintain its alliance with Amira, the ability and desire
of Inverness or Amira to provide additional funding, the extent to which Integ's
LIFEGuide System gains market acceptance, the timing of regulatory actions
regarding the LIFEGuide System, and the results of clinical trials and
competition.

             MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

    The following is a summary of material anticipated federal income tax
consequences of the merger to Integ shareholders who hold Integ common stock as
a capital asset. The summary is based on the Internal Revenue Code, referred to
herein as the Code, treasury regulations under the Code and administrative
rulings and court decisions in effect as of the date of the proxy statement and
prospectus, all of which are subject to change at any time, possibly with
retroactive effect. This summary does not consider the particular facts and
circumstances of the tax situation of each shareholder of Integ. Furthermore,
this summary does not discuss all of the consequences that may be relevant to
Integ shareholders subject to special treatment under United States federal
income tax law, including, for example, foreign persons, financial institutions,
dealers in securities, insurance companies, tax-exempt entities, holders who
acquired their Integ common stock pursuant to the exercise of employee stock
options or otherwise as compensation and holders who hold Integ common stock as
part of a hedge, straddle or conversion transaction. The following summary does
not purport to be a complete analysis of all potential tax effects of the
transactions contemplated by the merger agreement or the merger itself. No
information is provided in this summary with respect to the tax consequences, if
any, of the merger under state, local or foreign tax laws.

    EACH HOLDER OF INTEG COMMON STOCK IS URGED TO CONSULT SUCH HOLDER'S OWN TAX
ADVISOR AS TO THE FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER, AND ALSO AS TO
ANY STATE, LOCAL, FOREIGN OR OTHER TAX CONSEQUENCES, BASED ON SUCH HOLDER'S OWN
PARTICULAR FACTS AND CIRCUMSTANCES.

GENERAL

    Inverness and Integ expect that the merger will be treated as a tax-free
reorganization within the meaning of section 368(a) of the Code and that for
federal income tax purposes no gain or loss will be recognized by Integ
shareholders who exchange their shares of Integ common stock solely for shares
of Inverness common stock pursuant to the merger (except upon the receipt of
cash by an Integ shareholder in lieu of fractional shares of Inverness common
stock). The Internal Revenue Service has not been and will not be asked to rule
upon the tax consequences of the merger. Instead, Integ will rely upon the
opinion of Dorsey & Whitney LLP, its counsel, as to certain federal income tax
consequences of the merger and Inverness will rely on the opinion of Goodwin,
Procter & Hoar LLP, its counsel, as to certain federal income tax consequences
of the merger. It is a condition to the completion of the merger that each of
Inverness and Integ receive such a tax opinion. These tax opinions will be on
various representations and covenants made by Integ, Inverness and Terrier, and
are subject to various assumptions and qualifications. The tax opinions are also
based upon the Code, regulations now in effect under the Code, current
administrative rulings and practice, and judicial authority, all of which are
subject to change, possibly with retroactive effect. Unlike a ruling from the
Internal Revenue Service, an opinion of counsel is not binding on the IRS and
there can be no assurance, and none is hereby given, that the IRS will not take
a position contrary to the tax opinions or to one or more positions reflected in
this summary or that the tax opinions will be upheld by the courts if challenged
by the IRS.

    Based upon the facts described in this proxy statement and prospectus,
various representations and covenants made by Integ, Inverness and Terrier, and
subject to various assumptions and qualifications, each of Dorsey & Whitney LLP
and Goodwin, Procter & Hoar LLP will opine, as of the effective time of the
merger, that the merger will constitute a reorganization within the meaning of
section 368(a) of the Code and Integ, Inverness and Terrier each will be a party
to the reorganization within the meaning of section 368(b) of the Code. Assuming
the merger qualifies as a reorganization for purposes of the Code, the merger
will result in the following federal income tax consequences:

    - No income, gain or loss will be recognized by Integ, Inverness or Terrier
      as a result of the consummation of the merger.

                                       76
<PAGE>
    - Subject to the last bullet point below no gain or loss will be recognized
      by the holders of Integ common stock upon the exchange of Integ common
      stock solely for Inverness common stock pursuant to the merger.

    - The tax basis of the Inverness common stock received by an Integ
      shareholder pursuant to the merger, including any fractional shares deemed
      received as described in the last point below, will be the same as the tax
      basis of the Integ common stock surrendered in exchange therefor.

    - The holding period of the Inverness common stock received by a shareholder
      of Integ pursuant to the merger will include the period during which the
      Integ common stock surrendered in exchange therefor was held by such Integ
      shareholder, provided the Integ common stock is a capital asset in the
      hands of the Integ shareholder at the time of the merger.

    - Cash received by an Integ shareholder in lieu of a fractional share
      interest in Inverness common stock will generally be treated as received
      in redemption of such fractional share interest, and an Integ shareholder
      will generally recognize gain or loss, subject to the provisions and
      limitations of section 302 of the Code, which gain or loss will be capital
      gain or loss provided the Integ common stock was a capital asset in the
      hands of the Integ shareholder at the time of the merger. For United
      States federal income tax purposes, the gain or loss is measured by the
      difference between the amount of cash received and the portion of the tax
      basis of the share of Integ common stock allocable to such fractional
      share interest.

              INVERNESS MEDICAL TECHNOLOGY, INC. AND SUBSIDIARIES
      NOTES TO UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS

    On October 3, 2000, Inverness entered into an Agreement and Plan of Merger
with Integ for an aggregate of 1,900,000 shares of common stock of Inverness in
consideration for all of the outstanding capital stock, warrants and stock
options of Integ, and $5,500,000 to redeem all of Integ's preferred stock. The
acquisition will be accounted for as a purchase of assets. Accordingly, the
operating results of Integ will be included in the Inverness' financial results
from the date of acquisition. The allocation of the purchase price to the fair
value of the assets acquired will be based upon an independent appraisal of the
fair value of the assets of Integ. The computations of the value of Inverness'
common stock to be issued and the redemption value to be paid to the Integ
preferred stockholders will be revised upon consummation of the merger to
reflect actual amounts at the closing date. The preliminary purchase price
allocation included in the accompanying Unaudited Pro Forma Financial Statements
is based upon estimates made by management and will be revised upon completion
of the appraisal and consummation of the merger. The unaudited pro forma
combined condensed financial statements combine (i) the historical consolidated
balance sheets of the Company and Integ as of September 30, 2000 and (ii) the
historical statements of operations for the year ended December 31, 1999 and the
nine months ended September 30, 1999 and 2000 as if the acquisition was
consummated on January 1, 1999. The pro forma information is not necessarily
indicative of either the results which would have actually been reported if the
acquisition of Integ occurred on January 1, 1999 or results which may be
reported in the future.

                     DESCRIPTION OF INVERNESS CAPITAL STOCK

AUTHORIZED AND OUTSTANDING CAPITAL STOCK

    The certificate of incorporation of Inverness authorizes the issuance of up
to 40,000,000 shares of common stock, par value $.001 per share, and 5,000,000
shares of undesignated preferred stock, par value $.001 per share, issuable in
series by the board of directors of Inverness. The following is a summary
description of the capital stock of Inverness as provided in its amended and
restated certificate of incorporation and amended and restated bylaws. The
certificate of incorporation and bylaws have been adopted by the stockholders
and/or the board of directors of Inverness.

COMMON STOCK

    Holders of common stock are entitled to one vote per share on all matters to
be voted on by stockholders. Holders of common stock are not entitled to
cumulative voting rights. Therefore, the holders of a majority of the shares
voted in the election of directors can elect all of the directors then standing
for election, subject to the rights of the holders of preferred stock, if and
when issued. The holders of common stock have no preemptive or other
subscription rights.

    The holders of common stock are entitled to receive dividends, if any, as
may be declared from time to time by the board of directors from funds legally
available therefor, with each share of common stock sharing equally in these
dividends. The possible issuance of preferred stock with a preference over
common stock as to dividends could impact the dividend rights of holders of
common stock.

    There are no redemption or sinking fund provisions with respect to the
common stock. All outstanding shares of common stock are fully paid and
nonassessable.

    The bylaws provide, subject to the rights of the holders of the preferred
stock, if and when issued, that the number of directors shall be fixed by the
board of directors. The directors, other than those who may be elected by the
holders of preferred stock, if and when issued, are divided into three classes,
as nearly equal in number as possible, with each class serving for a three-year
term. Subject to any rights of the holders of preferred stock, if and when
issued, to elect directors, and to remove any director whom the holders of any
such stock had the right to elect, any director of Inverness may be removed from
office only for cause and by the affirmative vote of at least two-thirds of the
total votes that would be eligible to be cast by stockholders in the election of
such director.

UNDESIGNATED PREFERRED STOCK

    The board of directors of Inverness is authorized, without further action of
the stockholders of Inverness, to issue up to 5,000,000 shares of currently
undesignated preferred stock in classes or series and to fix the designations,
powers, preferences and the relative, participating, optional or other special
rights of the shares of each series and any qualifications, limitations and
restrictions thereon as set forth in the certificate of incorporation. Any such
preferred stock issued by Inverness may rank prior to the common stock as to
dividend rights, liquidation preference or both, may have full or limited voting
rights and may be convertible into shares of common stock.

    The purpose of authorizing the board of directors to issue preferred stock
is, in part, to eliminate delays associated with a stockholder vote on specific
issuances. The issuance of preferred stock could have the effect of making it
more difficult for a third party to acquire, or of discouraging a third party
from acquiring or seeking to acquire, a significant portion of the outstanding
stock of Inverness.


    As of December 15, 2000, Inverness did not have any preferred stock
outstanding.

CERTAIN PROVISIONS OF INVERNESS' CERTIFICATE OF INCORPORATION AND BYLAWS

    GENERAL.  A number of provisions of the certificate of incorporation and
bylaws of Inverness concern matters of corporate governance and the rights of
stockholders. Certain of these provisions, as well as the ability of the board
of directors of Inverness to issue shares of preferred stock and to set the
voting rights, preferences and other terms thereof, may be deemed to have an
anti-takeover effect and may discourage takeover attempts not first approved by
the board of directors, including takeovers that certain stockholders may deem
to be in their best interests. To the extent takeover attempts are discouraged,
temporary fluctuations in the market price of the Inverness common stock, which
may result from actual or rumored takeover attempts, may be inhibited.

    The certificate of incorporation provides for the board of directors to be
divided into three classes, as nearly equal in size as possible, of directors
serving staggered three-year terms. As a result, approximately one-third of the
board of directors will be elected each year. In addition, the certificate of
incorporation provides that stockholders may remove a director only for cause
and only by the vote of the holders of two-thirds of the common stock of
Inverness. This provision, when coupled with the provision of the certificate of
incorporation authorizing only the board of directors to fill vacant
directorships, will:

    - preclude stockholders from removing incumbent directors without cause and
      simultaneously gaining control of the board of directors by filling the
      vacancies created by such removal with their own nominees, and

    - will make more difficult, and therefore may discourage, a proxy contest to
      change control of Inverness.

    These provisions, together with the ability of the board to issue preferred
stock without further stockholder action, also could delay or frustrate the
removal of incumbent directors or the assumption of control by stockholders,
even if the removal or assumption would be beneficial to stockholders of
Inverness. In addition, these provisions could discourage or make more difficult
a merger, tender offer or proxy contest, even if they could be favorable to the
interests of stockholders, and could potentially depress the market price of the
common stock. The board of directors of Inverness believes that these provisions
are appropriate to protect the interests of Inverness and all of its
stockholders. The board of directors has no present plans to adopt any other
measures or devices that may be deemed to have an anti-takeover effect.

    MEETINGS OF STOCKHOLDERS.  Inverness' bylaws provide that a special meeting
of stockholders may be called only by the board of directors unless otherwise
required by law and subject to the rights, if any, of any series of preferred
stock of Inverness. Inverness' bylaws provide that only those matters set forth
in the notice of the special meeting may be considered or acted upon at that
special meeting, unless otherwise provided by law. In addition, Inverness'
bylaws set forth certain advance notice and informational requirements and time
limitations on any director nomination or any new business which a stockholder
wishes to propose for consideration at an annual meeting of stockholders.

    NO STOCKHOLDER ACTION BY WRITTEN CONSENT.  The certificate of incorporation
provides that any action required or permitted to be taken by the stockholders
of Inverness at an annual or special meeting of stockholders must be effected at
a duly called meeting and may not be taken or effected by a written consent of
stockholders in lieu thereof.

    INDEMNIFICATION AND LIMITATION OF LIABILITY.  The bylaws of Inverness
provide that directors and officers of Inverness will be, and in the discretion
of the board of directors, non-officer employees may be, indemnified by
Inverness to the fullest extent authorized by Delaware law, as it now exists or
may in the future be amended, against all expenses and liabilities reasonably
incurred in connection with service for or on behalf of Inverness. The bylaws of
Inverness also provide that the right of directors

                                       94
<PAGE>
and officers to indemnification shall be a contract right and shall not be
exclusive of any other right now possessed or hereafter acquired under any
bylaw, agreement, vote of stockholders or otherwise. The certificate of
incorporation also contains a provision permitted by Delaware law that generally
eliminates the personal liability of directors for monetary damages for breaches
of their fiduciary duty, including breaches involving negligence or gross
negligence in business combinations, unless the director has breached his or her
duty of loyalty, failed to act in good faith, engaged in intentional misconduct
or a knowing violation of law, paid a dividend or approved a stock repurchase in
violation of the Delaware General Corporation Law or obtained an improper
personal benefit. This provision does not alter a director's liability under the
federal securities laws. In addition, this provision does not affect the
availability of equitable remedies, such as an injunction or rescission, for
breach of fiduciary duty. Inverness believes that this provision will assist
Inverness in attracting and retaining qualified individuals to serve as
directors.

    AMENDMENT OF THE CERTIFICATE OF INCORPORATION.  The certificate of
incorporation provides that an amendment thereof must first be approved by a
majority of the board of directors and, with certain exceptions, thereafter
approved by the holders of a majority of the total votes eligible to be cast by
holders of voting stock with respect to such amendment or repeal and the
affirmative vote of a majority of the outstanding shares of each class entitled
to vote thereon as a class. However, the affirmative vote of two-thirds of the
total votes eligible to be cast by holders of voting stock, voting together as a
single class, and the affirmative vote of two-thirds of the outstanding shares
of each class entitled to vote thereon as a class, is required to amend
provisions relating to the establishment of the board of directors and
amendments to the certificate of incorporation.

    AMENDMENT OF BYLAWS.  The certificate of incorporation provides that the
bylaws may be amended or repealed by the board of directors or by the
stockholders. Such action by the board of directors requires the affirmative
vote of a majority of the directors then in office. Such action by the
stockholders requires the affirmative vote of the holders of at least two-thirds
of the total votes eligible to be cast by holders of voting stock with respect
to the amendment or repeal at an annual meeting of stockholders or a special
meeting called for the purpose, unless the board of directors recommends that
the stockholders approve the amendment or repeal at the meeting, in which case
the amendment or repeal shall only require the affirmative vote of a majority of
the total votes eligible to be cast by holders of voting stock with respect to
the amendment or repeal.

STATUTORY BUSINESS COMBINATION PROVISION


    Inverness is subject to the provisions of section 203 of the Delaware
General Corporation Law. Section 203 provides, with certain exceptions, that a
Delaware corporation may not engage in any of a broad range of business
combinations with a person or affiliate or associate of such person, who is an
"interested stockholder" for a period of three years from the date that such
person became an interested stockholder, unless:


    - the transaction resulting in a person becoming an interested stockholder,
      or the business combination, is approved by the board of directors of the
      corporation before the person becomes an interested stockholder;

    - the interested stockholder acquired 85% or more of the outstanding voting
      stock of the corporation in the same transaction that makes it an
      interested stockholder, excluding shares owned by persons who are both
      officers and directors of the corporation and shares held by certain
      employee stock ownership plans; or

    - on or after the date the person becomes an interested stockholder, the
      business combination is approved by the corporation's board of directors
      and by the holders of at least two-thirds of the corporation's outstanding
      voting stock at an annual or special meeting, excluding shares owned by
      the interested stockholder.

                                       95
<PAGE>
    Under section 203, an "interested stockholder" is defined, with certain
limited exceptions, as any person that is:

    - the owner of 15% or more of the outstanding voting stock of the
      corporation, or

    - an affiliate or associate of the corporation and was the owner of 15% or
      more of the outstanding voting stock of the corporation at any time within
      the three-year period immediately prior to the date on which it is sought
      to be determined whether the person is an interested stockholder.

    A corporation may, at its option, exclude itself from the coverage of
section 203 by amending its certificate of incorporation or by-laws by action of
its stockholders to exempt itself from coverage, provided that such bylaw or
charter amendment shall not become effective until 12 months after the date it
is adopted. Neither the certificate of incorporation nor the bylaws of Inverness
contains any such exclusion.

TRANSFER AGENT AND REGISTRAR

    Inverness' transfer agent and registrar for the Inverness common stock is
Equiserve.

  COMPARISON OF RIGHTS OF SHAREHOLDERS OF INTEG AND STOCKHOLDERS OF INVERNESS

    THIS SECTION OF THE PROXY STATEMENT AND PROSPECTUS DESCRIBES SOME
DIFFERENCES BETWEEN THE RIGHTS OF HOLDERS OF INTEG SHARES AND THE RIGHTS OF
HOLDERS OF INVERNESS SHARES. WHILE WE BELIEVE THAT THE DESCRIPTION COVERS THE
MATERIAL DIFFERENCES BETWEEN THE RIGHTS OF THE HOLDERS, THIS SUMMARY MAY NOT
CONTAIN ALL OF THE INFORMATION THAT IS IMPORTANT TO YOU. YOU SHOULD CAREFULLY
READ THIS ENTIRE DOCUMENT AND REFER TO THE OTHER DOCUMENTS DISCUSSED BELOW FOR A
MORE COMPLETE UNDERSTANDING OF THE DIFFERENCES BETWEEN YOUR RIGHTS AS A HOLDER
OF INTEG SHARES AND YOUR RIGHTS AS A HOLDER OF INVERNESS SHARES.

    As a shareholder of Integ, a Minnesota corporation, your rights will be
governed by Minnesota law, Integ's articles of incorporation, as currently in
effect, and Integ's amended bylaws, as currently in effect. After completion of
the merger, you will become a stockholder of Inverness, a Delaware corporation.
Inverness' common stock is quoted on the American Stock Exchange under the
symbol "IMA." As an Inverness stockholder, your rights will be governed by
Delaware law, Inverness' second amended and restated certificate of
incorporation, as amended, and Inverness' amended and restated bylaws. The
rights and privileges of stockholders of a Delaware corporation are in many
instances comparable to those of shareholders of a Minnesota corporation,
although there are also differences.

    The following discussion of similarities and material differences between
the rights of Integ shareholders under the articles of incorporation and bylaws
of Integ and the rights of Inverness stockholders under the certificate of
incorporation and bylaws of Inverness is only a summary of some provisions and
is not a complete description of these similarities and differences. This
discussion is qualified in its entirety by reference to Minnesota law and
Delaware law, the common law thereunder and the full texts of the certificate of
incorporation and bylaws of Inverness and the articles of incorporation and
bylaws of Integ. A holder of shares of a Minnesota corporation is termed a
"shareholder," and a holder of shares of a Delaware corporation is termed a
"stockholder." There is no material difference between the use of these terms.

SHAREHOLDER MEETINGS

    Bylaws governed by Delaware law require Delaware corporations to provide
stockholders with prior written notice no more than 60 days nor less than
10 days prior to the date of any meeting of stockholders. Delaware law provides
that notice must be given to stockholders at least 20 days prior to a meeting at
which the stockholders will be asked to approve and adopt an agreement relating
to the merger of a Delaware corporation.

    Under Minnesota law, shareholders are entitled to at least 10 days' prior
written notice for each regular meeting and special meeting to consider any
matter, unless a shorter time is provided for in the articles or bylaws. The
bylaws of Integ require that the shareholders be given at least 5 days' written
notice prior to each regular meeting and special meeting. However, Minnesota law
also requires that notice of a meeting at which an agreement of merger or
exchange is to be considered shall be mailed to all shareholders of record,
whether or not entitled to vote, at least 14 days prior to this meeting.

RIGHT TO CALL SPECIAL MEETINGS

    Under Delaware law, a special meeting of stockholders may be called by the
board of directors or by the person or persons who may be authorized by the
certificate of incorporation or by the bylaws. Inverness' bylaws authorize the
calling of a special meeting of stockholders only by the board of directors, and
no other person is authorized by Inverness' certificate of incorporation or
bylaws to call a special meeting. Therefore, stockholders of Inverness do not
have the right to call a special meeting of stockholders.

                                       97
<PAGE>
    Under Minnesota law and Integ's bylaws, a special meeting of shareholders
may be called by the chief executive officer, the chief financial officer, any
two or more directors, a person authorized in the articles or bylaws to call
special meetings, or a shareholder or shareholders holding 10% or more of the
voting power of all shares entitled to vote, except that a special meeting
called by a shareholder for the purpose of considering any action to directly or
indirectly facilitate or affect a business combination, including any action to
change or otherwise affect the composition of the board of directors for that
purpose, must be called by 25% or more of the voting power of all shares
entitled to vote. No person is specifically designated in Integ's articles or
bylaws to call a special meeting of shareholders.

ACTIONS BY WRITTEN CONSENT OF SHAREHOLDERS

    Under Delaware law, unless otherwise provided in the certificate of
incorporation, stockholders may act by a written consent in lieu of a meeting
provided the written consent is signed by the holders of outstanding stock
having not less than the minimum number of votes that would be necessary to
authorize or take such action at a meeting at which all shares entitled to vote
thereon were present and voted. Inverness' certificate of incorporation,
however, provides that all actions required or permitted to be taken by the
stockholders of the corporation must be effected at a duly called annual or
special meeting of stockholders of the corporation and may not be effected by
any consent in writing of stockholders.

    Under Minnesota law, any action required or permitted to be taken at a
meeting of shareholders may be taken without a meeting by a written action
signed by all shareholders entitled to vote on that action.

RIGHTS OF DISSENTING SHAREHOLDERS

    Under both Delaware and Minnesota law, stockholders and shareholders may,
under certain circumstances, exercise a right of dissent from certain limited
corporate actions and obtain payment for the fair value of their shares.
Generally, under Minnesota law, the categories of transactions subject to
dissenters' rights are broader than those under Delaware law.

    Appraisal rights are available under Delaware law with respect to the shares
of any class of stock of a constituent corporation to a merger unless these
shares were listed on a national securities exchange, designated as a national
market system security on an interdealer quotation system by the National
Association of Securities Dealers, Inc. or held of record by more than 2,000
stockholders. Notwithstanding the foregoing, appraisal rights are available
under Delaware law with respect to the shares of any class of stock of a
constituent corporation if the terms of a merger or consolidation require the
holders of the stock to exchange their stock for anything other than:

    - shares of the surviving corporation;

    - shares of another corporation that will be listed on a national securities
      exchange or designated as a national market system security on an
      interdealer quotation system by the National Association of Securities
      Dealers, Inc. or held of record by more than 2,000 holders;

    - cash in lieu of fractional shares of any such corporation; or

    - any combination of such shares and cash in lieu of fractional shares.

    Appraisal rights are also available under Delaware law, to the extent so
provided in the certificate of incorporation, in connection with amendments to
the certificate of incorporation, any merger or consolidation in which the
corporation is a constituent corporation, or sales of all or substantially all
of the assets of a corporation. Inverness' certificate of incorporation and
bylaws do not grant any dissenters' rights in addition to the statutorily
prescribed rights. Stockholders who desire to exercise their dissenters' rights
must satisfy all of the conditions and requirements as set forth in the Delaware

                                       98
<PAGE>
General Corporation Law in order to maintain these rights and obtain any payment
due in respect of the exercise of these rights.

    Shareholders of a Minnesota corporation may exercise dissenter's rights in
connection with:

    - an amendment of the articles of incorporation that materially and
      adversely affects the rights and preferences of the shares of the
      dissenting shareholder in certain respects;

    - a sale, lease, transfer or other disposition of all or substantially all
      of the assets of the corporation;

    - a plan of merger to which the corporation is a constituent organization;

    - a plan of exchange of shares to which the corporation is a party as the
      corporation whose shares will be acquired, if the shares are entitled to
      be voted on the plan of exchange; and

    - any corporate action taken pursuant to a shareholder vote which the
      corporation's articles of incorporation, bylaws or resolution approved by
      the board of directors grants dissenting shareholders the right to obtain
      payment for their shares.

    Unless the articles, the bylaws or a resolution approved by the board of
directors otherwise provide, these dissenters' rights do not apply to a
shareholder of (a) the surviving corporation in a merger with respect to shares
that are not entitled to be voted on the merger and are not canceled or
exchanged in the merger, or (b) the corporation whose shares will be acquired by
the acquiring corporation in a plan of exchange with respect to shares that are
not entitled to be voted on the plan of exchange and are not exchanged in the
plan of exchange. Integ's articles of incorporation, bylaws and approved board
resolutions do not grant any other dissenters' rights. Shareholders who desire
to exercise their dissenters' rights must satisfy all of the conditions and
requirements as set forth in the Minnesota Business Corporation Act in order to
maintain these rights and obtain any payment due in respect of the exercise of
these rights.

BOARD OF DIRECTORS

    Delaware law states that the board of directors must consist of one or more
members with the number of directors to be fixed as provided in the bylaws of
the corporation, unless the certificate of incorporation fixes the number of
directors, in which case a change in the number of directors shall be made only
by amendment of the certificate. Inverness' certificate of incorporation and
bylaws provide that the number of directors to constitute the whole board of
directors shall be fixed from time to time by resolution of the board of
directors. Inverness' board currently consists of eight directors.

    Delaware law also states that any director or the entire board of directors
may be removed, with or without cause, by the holders of a majority of the
shares then entitled to vote at an election of directors, with an exception for
corporations with cumulative voting. In the case of a corporation whose board is
divided into classes, holders only may remove a director for cause unless the
certificate of incorporation provides otherwise. Inverness' certificate of
incorporation provides for a classified board of directors in which the board of
directors is divided into three classes as nearly equal in number as may be
possible, with the term of office of one class expiring each year. Inverness'
certificate of incorporation does not provide for cumulative voting of
directors.

    Inverness' certificate of incorporation provides that a director may be
removed only for cause and only by the affirmative vote of the holders of
two-thirds of the shares entitled to vote at an election of directors. The
certificate defines "cause" to include:

    - conviction of a felony;

    - declaration of unsound mind by order of court;

                                       99
<PAGE>
    - gross dereliction of duty;

    - commission of any action involving moral turpitude; or

    - commission of an action that constitutes intentional misconduct or a
      knowing violation of law if such action in either event results in both an
      improper substantial personal benefit and a material injury to Inverness.

    Minnesota law provides that the board of directors of a Minnesota
corporation must consist of one or more directors as fixed by the articles of
incorporation or bylaws. Integ's bylaws provide that the Integ board of
directors shall consist of one or more directors and shall be increased or
decreased from time to time by resolution of the board of directors or the
shareholders. Integ's bylaws provide that the board is divided into three
classes, to be as nearly equal in number as reasonably possible. Integ currently
has six directors.

    Minnesota law provides that, unless modified by the articles or bylaws of
the corporation or by shareholder agreement, any one or all of the directors may
be removed with or without cause by the affirmative vote of the holders of a
majority of the voting power of all shares entitled to vote at an election of
directors, with an exception for corporations with cumulative voting. Integ's
articles and bylaws do not alter the statutory provisions regarding removal of
directors. Integ's articles of incorporation state that shareholders shall not
have any cumulative voting rights.

FILLING VACANCIES ON THE BOARD OF DIRECTORS

    Delaware law provides that, unless otherwise provided in the certificate of
incorporation or bylaws, vacancies and newly created directorships resulting
from any increase in the authorized number of directors may be filled with
directors elected by all the stockholders having the right to vote as a class or
by a majority of the directors then in office, although less than a quorum, or
by a sole remaining director. Further, if the directors then in office
constitute less than a majority of the whole board at the time of filling any
vacancy or newly created directorship, upon application of any stockholder or
stockholders holding at least 10% of the total number of the shares at the time
outstanding having the right to vote for directors, the Court of Chancery may
summarily order an election to be held to fill any vacancies or newly created
directorships or to replace the directors chosen by the directors then in
office. Inverness' certificate of incorporation provides that in case of any
vacancies, by reason of an increase in the number of directors or otherwise,
each additional director shall be elected by the affirmative vote of a majority
of the directors then in office, even though less than a quorum of the board of
directors, to serve until the end of the remainder of the term of the class to
which that director is assigned and until his or her successor has been elected
and qualified or until earlier resignation or removal. Furthermore, when the
number of directors is changed, any newly created directorships or any decrease
in directorships must be so apportioned among the classes by a majority of the
directors then in office.

    Under Minnesota law, unless different rules for filling vacancies are
provided for in the articles of incorporation or bylaws, vacancies resulting
from the death, resignation, removal or disqualification of a director may be
filled by the affirmative vote of a majority of the remaining directors, even
though less than a quorum, and vacancies resulting from a newly created
directorship may be filled by the affirmative vote of a majority of the
directors serving at the time of the increase. Each director elected to fill a
vacancy holds office until the shareholders elect a successor at the next annual
or special meeting. New directors may be elected at a meeting at which directors
are removed. Integ's bylaws provide that vacancies on the board of directors
resulting from death, resignation, removal or disqualification are to be filled
by a majority vote of the remaining directors, even if less than a quorum.
Integ's bylaws also provide that newly created directorships due to increases in
the size of the board of directors shall be filled by the majority vote of the
existing directors. Furthermore, all

                                      100
<PAGE>
directors filling vacancies or newly created directorships shall hold office
until their successors are elected at the next regular or special meeting of the
shareholders.

PREEMPTIVE RIGHTS

    A preemptive right allows a shareholder to maintain its proportionate share
of ownership of that corporation by permitting the shareholder to purchase a
proportionate share of any new stock issuances. Preemptive rights protect the
shareholders from dilution of value and control upon new stock issuances.

    Unless the certificate of incorporation of a Delaware corporation provides
otherwise, stockholders of a corporation have no preemptive rights. Inverness'
certificate does not provide for preemptive rights.

    Minnesota law provides that all shareholders are entitled to preemptive
rights unless the articles of incorporation specifically deny or limit
preemptive rights. Integ's articles of incorporation provide that shareholders
do not have preemptive rights.

ADVANCE NOTICE REQUIREMENT OF SHAREHOLDER PROPOSALS AND DIRECTOR NOMINATIONS

    Inverness' bylaws provide that for a proposal to be properly brought before
an annual meeting by a stockholder, the stockholder must give proper written
notice of his or her intent to bring a matter before the annual meeting and must
also be present at this meeting. The bylaws state that notice is timely if it is
mailed to and received by Inverness' principal executive office no less than
75 days nor more than 120 days prior to the anniversary date of the preceding
annual meeting.

    Inverness' bylaws provide that any stockholder who is a holder of record,
both as of the time notice of the nomination is given and as of the record date
for the annual meeting in question, and who is entitled to vote in the election
of directors generally may nominate one or more persons for election as a
director if certain timing, informational and other requirements set out in the
bylaws are met. Furthermore, the stockholder proposing the nomination and each
person so nominated shall be present at the meeting in order for the nomination
to be properly before the meeting at which the nominations are to be considered.
Inverness' bylaws also provide that, with certain exceptions, notice of
nomination is timely, if it is received in writing by the secretary of the
corporation no less than 75 days nor more than 120 days prior to the anniversary
date of the annual meeting of the previous year. The bylaws require that this
notice provide certain detailed information about both the nominating
stockholder and the nominated individual or individuals.

    Integ's bylaws provide that for a shareholder proposal to be properly made
by a shareholder at a regular meeting, the matter must be proper for shareholder
action, and the shareholder must be entitled to vote at the meeting, must give
prior notice of the matter and must be a shareholder of record at the time of
giving notice. The bylaws require that the shareholder give written notice of
the proposal containing the information required by Rule 14a-8 under the
Securities Exchange Act to the chief executive officer or secretary of the
corporation no later than the end of the fifteenth business day following the
day on which the notice of the regular meeting was mailed to shareholders.
Integ's bylaws also provide that for a nomination of a director to be properly
made by a shareholder at a regular meeting, the shareholder must be entitled to
vote at the meeting, must give prior written notice of the nomination to the
secretary of the corporation no later than the end of the fifteenth business day
following the day on which the notice of the shareholder meeting was mailed to
shareholders and must be a shareholder of record at the time of giving notice.

                                      101

AMENDMENTS TO BYLAWS AND ARTICLES

    In order to amend the certificate of incorporation of a Delaware
corporation, Delaware law requires the approval of the corporation's board of
directors followed by the affirmative vote of a majority of the outstanding
stock of each class entitled to vote, unless the certificate of incorporation
requires a greater level of approval. Further, Delaware law states that if an
amendment would increase or decrease the aggregate number of authorized shares
of a particular class, increase or decrease the par value of shares of a
particular class or alter or change the powers, preferences or special rights of
a particular class or series of stock so as to affect them adversely, the class
shall be given the power to vote as a class notwithstanding the absence of any
specifically enumerated power in the certificate of incorporation. If any
proposed amendment would alter or change the powers, preferences or special
rights of one or more series of any class so as to affect them adversely, but
shall not so affect the entire class, then only the shares of the series so
affected by the amendment shall be considered a separate class for the purposes
of this paragraph. Inverness' certificate of incorporation states that Inverness
cannot amend or otherwise modify or repeal certain provisions of the Inverness
certificate relating to stockholder action, election and terms of directors,
breach of director fiduciary duties and liability, and amending its certificate
of incorporation without the affirmative vote of the holders of record of
two-thirds of all the shares outstanding and entitled to vote and the approval
of two-thirds of each class of shares.

    Delaware law also states that the stockholders have the power to adopt,
amend or repeal the bylaws of a corporation, provided that the corporation in
its certificate of incorporation may confer such powers on the board of
directors in addition to the stockholders. Inverness' certificate of
incorporation and bylaws permit the board of directors to adopt, amend, alter
and repeal the bylaws of the corporation. Inverness' certificate of
incorporation provides that the bylaws also may be altered, amended or repealed
at any regular meeting of stockholders or special meeting called for that
purpose, by the affirmative vote of two-thirds of the shares present and
entitled to vote. Inverness' certificate of incorporation provides that this
requirement of the vote of two-thirds of the shares is reduced to the
requirement of the vote of a majority of the shares if the board recommends that
stockholders approve the amendment or repeal at such a meeting.

    Minnesota law provides that unless reserved by the articles of incorporation
to the shareholders, the power to adopt, amend or repeal the bylaws is vested in
the board, subject to the power of the shareholders to adopt, amend or repeal
bylaws adopted, amended or repealed by the board. Under Minnesota law, a
shareholder or shareholders holding 3% or more of the voting shares entitled to
vote may propose a resolution to adopt, amend or repeal bylaws adopted, amended
or repealed by the board, in which event the resolutions must be brought before
the shareholders for their consideration pursuant to the procedures for amending
the articles of incorporation. Under Minnesota law and Integ's bylaws, the board
of directors are not permitted to adopt, amend or repeal any bylaws once adopted
that fix a quorum for meetings of shareholders, prescribe procedures for
removing directors or fill vacancies in the board of directors, or fix the
number of directors or their classifications, qualifications or terms of office.
These actions are reserved to the shareholders. However, Minnesota law does
provide that the board of directors may adopt or amend a bylaw to increase the
number of directors, and Integ's bylaws permit this action without amendment of
the bylaws. Integ's bylaws and articles are silent as to amendment of its
bylaws.

    Minnesota law provides that a proposal to amend the articles of
incorporation may be presented to the shareholders of a Minnesota corporation by
a resolution either approved by the affirmative vote of a majority of the
directors present or proposed by a shareholder or shareholders holding 3% or
more of the voting shares entitled to vote thereon. Under Minnesota law, any
such amendment must be approved by the affirmative vote of a majority of the
shareholders entitled to vote thereon, except that the articles may provide for
a specified proportion or number greater than a majority.

                                      102
<PAGE>
    In addition, under Minnesota law, the holders of the outstanding shares of a
class or series are entitled to vote as a class or series on a proposed
amendment to the articles of incorporation, whether or not that class or series
would otherwise be entitled to vote, if the amendment would:

    - alter the aggregate number of authorized shares of the applicable class or
      series;

    - effect an exchange, reclassification or cancellation of all or part of the
      class or series;

    - effect an exchange or create a right of exchange of all or a part of
      another class or series for the shares of the applicable class or series;

    - change the rights or preferences of the shares of the applicable class or
      series;

    - change the shares of the class or series into the same or a different
      number of shares of another class or series;

    - create a new class or series with rights or preferences prior and superior
      to the shares of the applicable class or series or increase the rights and
      preferences or the number of authorized shares, of a class or series
      having rights and preferences prior or superior to the shares of the
      applicable class or series;

    - divide the shares of the applicable class into series and determine the
      designation of each series and the variations in the relative rights and
      preferences between the shares of each series, or authorize the board to
      do so;

    - limit or deny any existing preemptive rights of the shares of the
      applicable class or series; or

    - cancel or otherwise affect distributions on the shares of the applicable
      class or series that have accrued but have not been declared.

INDEMNIFICATION OF DIRECTORS, OFFICERS AND EMPLOYEES

    Minnesota law and Delaware law both contain provisions setting forth
conditions under which a corporation may indemnify its directors, officers and
employees. Specifically, the person to be indemnified must have acted in good
faith and in a manner the person reasonably believed to be in, or not opposed
to, the best interests of the corporation and, with respect to any criminal
action or proceeding, had no reasonable cause to believe that the conduct was
unlawful. Minnesota and Delaware law differ, however, with respect to whether
indemnification is permissive or mandatory, where there is a distinction between
third-party actions and actions by or in the right of the corporation, and
whether, and to what extent, reimbursement of judgments, fines, settlements and
expenses is allowed. The primary difference between Minnesota law and Delaware
law is that while indemnification of officers, directors and employees is
mandatory under Minnesota law, indemnification is permissive under Delaware law,
except that a Delaware corporation must indemnify a present or former director
or officer who is successful on the merits or otherwise in the defense of some
specified actions, suits or proceedings for expenses, including attorney's fees,
actually and reasonably incurred in connection therewith.

    Although indemnification is permissive in Delaware, a corporation may,
through its certificate of incorporation, bylaws or other intracorporate
agreements, make indemnification mandatory. Pursuant to this authority,
Inverness' bylaws provide that any person who serves or has served as a director
or officer of the corporation or in any other office filled by election or
appointment by the stockholders or the board of directors of the corporation and
any heirs, executors, administrators or personal representatives of such person
shall be indemnified and held harmless by the corporation to the fullest extent
authorized by the Delaware General Corporation Law. This indemnification is to
cover all related expenses incurred by the person in connection with any
proceeding in which the person is involved. Additionally, pursuant to the merger
agreement entered into between Integ and Inverness,

                                      103
<PAGE>
Inverness will maintain a liability insurance policy providing coverage for the
directors and officers of Integ.

    The bylaws of Inverness also permit the board of directors, in its
discretion, to permit the corporation to indemnify to the fullest extent
authorized by the Delaware General Corporation Law any other employee of the
company. The indemnification can be for any expenses incurred by the employee in
connection with any proceeding in which he or she is involved as a result of
serving or having served (a) as an employee of the corporation who is neither a
director nor officer, (b) as a director, officer or employee of any subsidiary
of the corporation, or (c) in any capacity with any other corporation,
organization, partnership, joint venture, trust or any other entity at the
request or direction of the corporation.

    However, Inverness' bylaws also provide that no indemnification may be
provided for any person unless a determination has been made that the person
acted in good faith and in a manner he or she reasonably believed to be in, or
not opposed to, the best interests of the corporation, and with respect to any
criminal proceeding, the person had no reasonable cause to believe his or her
conduct was unlawful. The bylaws provide that this determination shall be made
(a) by a majority vote of disinterested directors, (b) by the stockholders or
(c) at the direction of a majority of disinterested directors, by independent
legal counsel in a written opinion.

    Minnesota law requires a corporation to indemnify any director, officer or
employee who is made or threatened to be made a party to a proceeding by reason
of the former or present official capacity of the director, officer or employee,
against judgments, penalties, fines, settlements and reasonable expenses.
Minnesota law permits a corporation to prohibit indemnification by so providing
in its articles of incorporation or its bylaws. Integ's bylaws provide that all
officers and directors of the corporation shall be indemnified by the
corporation for those expenses and liabilities, in that manner, under those
circumstances and to the fullest extent permitted by Minnesota law. However,
Integ's bylaws prohibit indemnification of any other employees of the company,
unless otherwise approved by Integ's board of directors.

LIABILITIES OF DIRECTORS

    Under Delaware law, a certificate of incorporation may contain a provision
limiting or eliminating a director's personal liability to the corporation or
its stockholders for monetary damages for a director's breach of fiduciary duty,
subject to certain limitations. Pursuant to this authority, Inverness'
certificate of incorporation provides that the directors of Inverness shall not
be personally liable to the corporation or its stockholders for monetary damages
for breach of fiduciary duty as a director, except for liability:

    - for any breach of the director's duty of loyalty to the corporation or its
      stockholders;

    - for acts or omissions not in good faith or which involve intentional
      misconduct or a knowing violation of the law;

    - under section 174 of the Delaware General Corporation Law, which provides
      for unlawful payment of dividend or unlawful stock purchase or redemption;
      or

    - for any transaction from which the director derived an improper personal
      benefit.

    Inverness' certificate of incorporation also provides that if Delaware law
is amended to eliminate or limit the liability of directors further, then the
liability of Inverness' directors shall be limited to the fullest extent
permitted by Delaware law, as so amended.

                                      104
<PAGE>
    Under Minnesota law, a director's personal liability to the corporation or
its shareholders for monetary damages for breach of fiduciary duty as a director
may be eliminated or limited in the articles except that the articles cannot
limit the liability of a director:

    - for any breach of the director's duty of loyalty to the corporation or its
      shareholders;

    - for acts or omissions not in good faith or that involve intentional
      misconduct or a knowing violation of the law;

    - under section 302A.559 of the Minnesota Business Corporation Act or
      section 80A.23 of the Minnesota Regulation of Securities Act, which
      provide for liability for illegal distributions and civil liability,
      respectively;

    - for any transaction from which the director derived an improper benefit;
      or

    - for any act or omission occurring prior to the date when the provision in
      the articles eliminating liability becomes effective.

    Integ's articles provide that directors of the corporation are to be
protected from personal liability to the corporation or its shareholders for
monetary damages for breach of fiduciary duty as a director to the fullest
extent permitted by the Minnesota Business Corporation Act.

SHAREHOLDER APPROVAL OF A MERGER

    In order to effect a merger under Delaware law, a corporation's board of
directors must adopt an agreement of merger or consolidation and recommend it to
the stockholders. The agreement must be approved and adopted by holders of a
majority of the outstanding shares of the corporation entitled to vote thereon,
unless a higher percentage is specified in the corporation's certificate of
incorporation.

    Minnesota law provides that a resolution containing a plan of merger or
exchange must be approved by the affirmative vote of a majority of the directors
present at a meeting and submitted to the shareholders and approved by the
affirmative vote of the holders of a majority of the voting power of all shares
entitled to vote. Unlike Delaware law, Minnesota law requires that any class of
shares of a Minnesota corporation must be given the right to approve the plan if
it contains a provision which, if contained in a proposed amendment to the
corporation's articles of incorporation, would entitle such a class to vote as a
class.

BUSINESS COMBINATIONS, CONTROL SHARE ACQUISITIONS AND ANTI-TAKEOVER PROVISIONS

    Delaware law prohibits, in some circumstances, a "business combination"
between the corporation and an "interested stockholder" within three years of
the stockholder becoming an "interested stockholder." An "interested
stockholder" is a holder who, directly or indirectly, owns 15% or more of the
outstanding voting stock or is an affiliate of the corporation and was the owner
of 15% or more of the outstanding voting stock at any time within the prior
three-year period. A "business combination" includes a merger or consolidation,
a sale or other disposition of assets having an aggregate market value equal to
10% or more of the consolidated assets of the corporation or the aggregate
market value of the outstanding stock of the corporation, any transaction
resulting in the issuance or transfer of stock by the corporation, or certain of
its subsidiaries, with exceptions, and certain transactions that would increase
the interested stockholder's proportionate share ownership in the corporation.
This provision does not apply where:

    - either the business combination or the transaction that resulted in the
      stockholder becoming an interested stockholder is approved by the
      corporation's board of directors prior to the date the interested
      stockholder acquired a 15% interest;

                                      105
<PAGE>
    - upon the consummation of the transaction that resulted in the stockholder
      becoming an interested stockholder, the interested stockholder owned at
      least 85% of the outstanding voting stock of the corporation excluding,
      for the purposes of determining the number of shares outstanding, those
      shares held by persons who are directors and also officers and by employee
      stock plans in which participants do not have the right to determine
      confidentially whether shares held subject to the plan will be tendered;

    - the business combination is approved by a majority of the board of
      directors and the affirmative vote of two-thirds of the outstanding votes
      entitled to be cast by disinterested stockholders at an annual or special
      meeting;

    - the corporation does not have a class of voting stock that is listed on a
      national securities exchange, authorized for quotation on the Nasdaq Stock
      Market, or held of record by more than 2,000 stockholders unless any of
      the foregoing results from action taken, directly or indirectly, by an
      interested stockholder or from a transaction in which a person becomes an
      interested stockholder;

    - the stockholder acquires a 15% interest inadvertently and divests itself
      of such ownership and would not have been a 15% stockholder in the
      preceding 3 years but for the inadvertent acquisition of ownership;

    - the stockholder acquired the 15% interest when these restrictions did not
      apply; or

    - the corporation has opted out of this provision. Inverness has not opted
      out of this provision.

    Minnesota law prohibits certain "business combinations," as defined in the
Minnesota Business Corporation Act, between a Minnesota corporation with at
least 100 shareholders, or a publicly held corporation that has at least 50
shareholders, and an "interested shareholder" for a four-year period following
the share acquisition date by the interested shareholder, unless certain
conditions are satisfied or an exemption is found. An "interested shareholder"
is generally defined to include a person who beneficially owns at least 10% of
the voting power of the outstanding shares entitled to vote of the issuing
public corporation. Minnesota law also limits the ability of a shareholder who
acquires beneficial ownership of more than certain thresholds of the percentage
voting power of a Minnesota corporation, starting at 20%, from voting those
shares in excess of the threshold unless such acquisition has been approved in
advance by a majority of the voting power held by shareholders unaffiliated with
the interested shareholder.

    Minnesota law provides that during any tender offer, a publicly held
corporation may not enter into or amend an agreement, whether or not subject to
contingencies, that increases the current or future compensation of any officer
or director. In addition, under Minnesota law, a publicly held corporation is
prohibited from purchasing any voting shares owned for less than two years from
a 5% shareholder for more than the market value unless the transaction has been
approved by the affirmative vote of the holders of a majority of the voting
power of all shares entitled to vote or unless the corporation makes a
comparable offer to all holders of shares of the class or series of stock held
by the 5% shareholder and to all holders of any class or series into which such
securities may be converted.

    The provisions of Integ's bylaws providing for a staggered board of
directors and requiring the request of holders of at least 25% of the
outstanding shares to call a special meeting of shareholders involving a
business combination, or any change in the composition of the board of directors
as a result of such business combination, make it more difficult to effect a
change in control of Integ and may discourage or deter a third party from
attempting a takeover.

    The foregoing discussion of certain similarities and material differences
between the rights of Inverness stockholders and the rights of Integ
shareholders under Inverness' certificate of incorporation

                                      106
<PAGE>
and bylaws and Integ's articles of incorporation and bylaws is only a summary of
certain provisions and does not purport to be a complete description of the
similarities and differences, and is qualified in its entirety by reference to
Delaware law and Minnesota law, the common law thereunder and the full text of
the certificate of incorporation and bylaws of Inverness and the articles of
incorporation and bylaws of Integ.

                         REPORT OF INDEPENDENT AUDITORS

BOARD OF DIRECTORS
INTEG INCORPORATED

    We have audited the accompanying balance sheets of Integ Incorporated (a
development stage company) as of December 31, 1999 and 1998 and the related
statements of operations, changes in shareholders' equity (deficiency) and cash
flows for each of the three years in the period ended December 31, 1999, and for
the period from April 3, 1990 (inception) to December 31, 1999. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

    We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Integ Incorporated at
December 31, 1999 and 1998 and the results of its operations and its cash flows
for each of the three years in the period ended December 31, 1999, and for the
period from April 3, 1990 (inception) to December 31, 1999, in conformity with
accounting principles generally accepted in the United States.

                         NOTES TO FINANCIAL STATEMENTS

                               DECEMBER 31, 1999

1.  DESCRIPTION OF BUSINESS

    Integ Incorporated was formed in April 1990 and is a development stage
company engaged in the development of a handheld glucose monitoring product for
use by people with diabetes that avoids the pain and blood associated with
conventional "finger-stick" technology. Utilizing the Company's proprietary
interstitial fluid sampling technology, the LifeGuide System will allow people
with diabetes to frequently monitor their glucose levels without repeatedly
enduring the pain of lancing their fingers to obtain a blood sample.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

CASH AND CASH EQUIVALENTS

    The Company considers all highly liquid investments purchased with a
maturity of three months or less when purchased to be cash equivalents. At
December 31, 1999 and 1998, the Company's cost of investments in marketable
securities and government securities, respectively, approximated market value,
with no resulting unrealized gains and losses recognized. The cash equivalents
are considered available-for-sale.

FURNITURE AND EQUIPMENT

    Furniture and equipment are recorded at cost and depreciated primarily on a
straight-line basis over estimated useful lives of three to five years.

INCOME TAXES

    The Company accounts for income taxes under the liability method. Deferred
income taxes are provided for temporary differences between the financial
reporting and tax bases of assets and liabilities.

STOCK COMPENSATION PLANS

    The Company follows Accounting Principles Board Opinion No. 25, ACCOUNTING
FOR STOCK ISSUED TO EMPLOYEES ("APB 25"), and related interpretations in
accounting for its stock options. Under APB 25, when the exercise price of stock
options equals the market price of the underlying stock on the date of grant, no
compensation expense is recognized.

    The Company follows the disclosure only provisions of Financial Accounting
Standards No. 123, ACCOUNTING FOR STOCK-BASED COMPENSATION ("Statement 123").
Accordingly, the Company has made pro forma disclosures of what net loss and
loss per share would have been had the provisions of Statement 123 been applied
to the Company's stock options.

NET LOSS PER SHARE

    Basic net loss per share is computed using the weighted average number of
shares of common stock outstanding during the periods presented. Diluted loss
per share is the same as basic loss because the effect of all options and
warrants is anti-dilutive.

                               DECEMBER 31, 1999

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
AUTOMATIC CONVERSION OF PREFERRED STOCK

    Upon the closing of the initial public offering on July 1, 1996, all
outstanding shares of convertible preferred stock were automatically converted
into an aggregate of 5,835,705 shares of common stock.

RECLASSIFICATIONS

    Certain amounts in the 1997 and 1998 financial statements have been
reclassified to conform with the 1999 presentation.

USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

INTERIM FINANCIAL INFORMATION

    The accompanying financial statements as of September 30, 2000, and for the
nine month periods ended September 30, 2000, and 1999, and the period from
April 3, 1990 (inception) to September 30, 2000, are unaudited and do not
include all the information and notes required by Generally Accepted Accounting
Principles for complete financial statements. In the opinion of management,
these financial statements reflect all adjustments, consisting only of normal
and recurring adjustments necessary for a fair presentation of the financial
statements. The results of operations for the nine month period ended September
30, 2000, are not necessarily indicative of the results that may be expected for
the full year ending December 31, 2000.

3.  CAPITAL AND OPERATING LEASES

    The Company leases its office facility and certain office equipment under
operating leases. Rent expense of $400,958, $377,485 and $432,686 was recorded
for noncancelable operating leases and sub-leases for the years ended
December 31, 1999, 1998 and 1997, respectively. Future minimum lease commitments
for operating leases with remaining terms in excess of one year, excluding
executory costs such as real estate taxes, insurance and maintenance expense,
are payable as follows:

5.  LICENSE AND DEVELOPMENT AGREEMENT

    On April 2, 1999, the Company entered into a Development and License and
Agreement ("License Agreement") with Amira Medical ("Amira"). Under the License
Agreement, the companies have formed a strategic alliance to jointly develop a
new generation of home glucose monitoring tests utilizing interstitial fluid
("ISF"). Products to be developed will combine the Company's ISF collection
technology with Amira's glucose measurement technologies. Both the Company and
Amira will contribute resources to the development of the product, which will be
manufactured by the Company and commercialized by Amira. As part of each party's
contribution to the development process, each party shall independently bear the
costs and contribute the resources necessary for the development activities for
which each party is responsible. In the event Integ exhausts its resources,
Amira will lend Integ minimum funding required to retain listing on one of
NASDAQ's markets. Any such loan will be unsecured. (See Note 12 for further
developments related to this agreement.)

5.  LICENSE AND DEVELOPMENT AGREEMENT (CONTINUED)
    In connection with the License Agreement, the Company and Amira entered into
an Option Agreement dated as of April 2, 1999, pursuant to which Amira granted
to the Company, an option, exercisable at a future date, to merge under certain
circumstances with a wholly-owned, newly formed subsidiary of Amira for a total
consideration of 2 million shares of Amira common stock and $20 million cash,
subject to certain conditions. The Option Agreement was entered into as a
condition and inducement to the Company's and Amira's willingness to enter into
the License Agreement.

6.  REDEEMABLE CONVERTIBLE PREFERRED STOCK AND PREFERRED STOCK

    Series A, B, C, D and E Convertible Preferred Shares issued in 1995 were
automatically converted three shares of preferred into two shares of common
stock upon the closing of the public offering of the Company's securities on
July 1, 1996.

7.  REVERSE STOCK SPLIT

    On April 24, 1996, the Board of Directors approved a reverse stock split of
2-for-3 for the Company's common stock. Accordingly, all share, per share,
weighted average share, and stock option information was restated to reflect the
split. The reverse stock split impacted the conversion prices of the preferred
stock and the numbers of shares of common stock into which the preferred stock
would convert but had no effect upon the numbers of preferred stock warrants and
shares of preferred stock issued and outstanding. Accordingly, all preferred
stock and preferred stock price amounts have not been adjusted for the reverse
stock split.

8.  STOCK OPTIONS AND WARRANTS

STOCK OPTIONS AND RESTRICTED STOCK GRANT

    The Company has 1990, 1991 and 1994 stock option plans which provide for the
issuance of incentive and nonqualified stock options and restricted stock grants
to employees and consultants. Under the plans, the exercise price of options
granted is determined by the Company's Board of Directors, but incentive stock
options must be granted at exercise prices greater than or equal to the fair
market value of the Company's stock as of the grant date. A total of 3,213,333
shares of the Company's common stock have been reserved for issuance under all
three plans as of December 31, 1999.

    During 1998, the Company repriced all outstanding employee options and those
held by consultants who were actively engaged in consulting activities as of
September 22, 1998 to an exercise price of $.81 per share. The Company valued
the repricing of the consultant options at $35,425 and is recognizing the
expense over the vesting period of the options.

    During 1991 and 1993, the Company granted options outside the plans to
purchase 42,993 shares of the Company's common stock at $.83 per share to
Medical Innovation Fund ("MIF"), a significant shareholder of the Company (see
Note 11).

    Options outstanding expire at various dates during the period from
October 2000 through December 2009. The number of options exercisable as of
December 31, 1999, 1998 and 1997 was 1,020,378, 703,093 and 710,982,
respectively, at weighted average prices of $3.88, $3.00 and $3.92 per share,
respectively.

    The weighted average grant date fair value of options granted at market
prices during the years ended December 31, 1999, 1998 and 1997 was $1.93, $1.43
and $4.92 per share, respectively. The

8.  STOCK OPTIONS AND WARRANTS (CONTINUED)
weighted average grant date fair value of options granted below market prices
during the years ended December 31, 1995 and 1996 was $4.01 and $6.93 per share,
respectively.

    The Company has elected to follow Accounting Principles Board Opinion
No. 25, ACCOUNTING FOR STOCK ISSUED TO EMPLOYEES ("APB 25"), and related
Interpretations in accounting for its employee stock options because, as
discussed below, the alternative fair value accounting provided for under FASB
Statement No. 123, ACCOUNTING FOR STOCK-BASED COMPENSATION ("Statement 123"),
requires use of option valuation models that were not developed for use in
valuing employee stock options. Under APB 25, if the exercise price of the
Company's employee stock options equals or exceeds the market price of the
underlying stock on the date of grant, no compensation expense is recognized.

    Pro forma information regarding net loss per share is required by Statement
123, and has been determined as if the Company had accounted for its employee
stock options under the fair value method of Statement 123. The fair value for
these options was estimated at the date of grant using the Black-Scholes option
pricing model with the following weighted average assumptions for 1999, 1998 and
1997: risk free interest rates of 5.60%, 5.31% and 6.33%, respectively; no
dividend yield; volatility factor of the expected market price of the Company's
common stock of .560, 1.047 and .656, respectively; and a weighted-average life
of the option of 10 years.

    The Black-Scholes option valuation model was developed for use in estimating
the fair value of traded options which have no vesting restrictions and are
fully transferable. In addition, option valuation models require the input of
highly subjective assumptions. Because the Company's employee stock options have
characteristics significantly different from those of traded options, and
because changes in the subjective input assumptions can materially affect the
fair value estimate, in management's opinion, the existing models do not
necessarily provide a reliable single measure of the fair value of its employee
stock options.

    For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. The Company's
pro forma information is as follows:

</TABLE>

    The pro forma effect on net loss for 1997, 1998 and 1999 is not
representative of the pro forma effect on net loss in future years because it
does not take into consideration pro forma compensation expense related to
grants made prior to 1995.

    During 1995 and 1996, options were granted to purchase a total of 433,710
shares of the Company's common stock at exercise prices below the current market
price. The Company recognized $960,208 and $56,329 during the years ended 1995
and 1996, respectively, as deferred compensation for the excess of the deemed
value of the underlying common stock over the aggregate exercise price of such
options. The deferred compensation is amortized ratably over the vesting period
of the options. For the years ended 1996, 1997 and 1998, $477,076, $314,096 and
$225,365, respectively, was expensed.

1992 and 1993, the Company issued warrants to the holders for the purchase of
46,665 shares (including warrants for 13,333 shares issued to MIF (see

Partnership) of its common stock exercisable immediately at a price of $3.75 per
share. These MIF and Artesian Capital Limited Partnership warrants were

During May 1994, the Company issued warrants which expired during May 1999 to a
consultant/stockholder for the purchase of 6,666 shares of common stock
exercisable immediately at a price of $4.13 per share. The value of these

received, and was expensed. In addition, during March and December of 1994 and
June 1995, the Company issued warrants for the purchase of 159,042 shares of
Series D Convertible Preferred Stock (convertible into 106,027 shares of common

on the difference between the stated interest rate and the Company's estimated
effective borrowing rate for the term of the notes and was expensed as
additional interest expense during 1995.

    In consideration of the equipment loan agreement discussed in Note 4, the

9.  EMPLOYEE STOCK PURCHASE PLAN

    The 1997 Employee Stock Purchase Plan (the Purchase Plan), as approved by
the shareholders on June 4, 1997, is a qualified plan pursuant to Internal
Revenue Code Section 423. The Purchase Plan allows eligible employees an
opportunity to purchase an aggregate of 300,000 shares of the Company's common
stock through a series of annual offerings for each calendar year (except for
the initial purchase period of the Purchase Plan which was for a six month
period beginning July 1, 1997). Payroll deductions between 1% and 10% of an
employee's eligible compensation may be used to purchase stock at a price per
share equal to 85% of the lesser of the fair market value of the Company's
common stock at the beginning or end of each purchase period. Under terms of the
Purchase Plan, no participant may acquire more than 10,000 shares of the
Company's common stock or more than $10,000 in aggregate fair market value of
common stock (as determined at the beginning of each purchase period) during any
purchase period. Common shares sold to employees under the Purchase Plan in 1998
and 1999 totaled 44,428 and 58,590, respectively.

10.  INCOME TAXES

    The Company has incurred net operating losses since inception. As of

development tax credit carryforwards of approximately $17,203,000 and
$1,079,000, respectively, available to offset its future income tax liability.
The NOL and tax credit carryforwards begin to expire in the year 2005. No
benefit has been recorded for such loss carryforwards, and utilization in future
years may be limited, if significant ownership changes have occurred.

are significant shareholders of the Company. These leases are accounted for as
capital leases for financial statement purposes. In addition, MIF and MIF II
have guaranteed future lease payments, of which approximately $12,760 is payable
as of December 31, 1999. In consideration of such guarantee by MIF, the Company
issued nonqualified options to MIF for the purchase of 42,993 shares of common
stock exercisable immediately at a price of $.83 per share. Options for 30,523
shares expire during May 2001 and options for 12,470 shares expire during
April 2003. The value of these options was determined to be $20,878 based on the
difference between the stated interest rate and the Company's estimated
effective borrowing rate for the term of the lease and was fully amortized by
December 31, 1998. In consideration of such guarantee by MIF II, the Company
issued warrants to MIF II for the purchase of 131,769 shares of Series D
Convertible Preferred Stock exercisable immediately at a price of $2.75 per
share which are convertible into 87,845 shares of common stock at $4.13 per
share. These warrants expire during the period from December 2004 through
June 2005. The value of these warrants was determined to be $83,962 based on the
difference between the stated interest rate and the Company's estimated
effective borrowing rate for the term of the lease. Approximately $15,304,
$18,267 and $22,689 was charged to interest expense during the years ended
December 31, 1999, 1998 and 1997, respectively, and the remainder will be
amortized over the term of the lease.

    In consideration of the bridge loan arrangement during January 1995
discussed in Note 8, the Company issued to MIF II warrants for the purchase of
222,222 shares of Series E Convertible Preferred Stock, Class 2, exercisable
immediately at a price of $3.375 per share and convertible into 148,148 shares
of common stock at $5.06 per share. The value of these warrants was determined
to be $93,000 of the $179,800 total discussed in Note 8. These warrants expire
during January 2005.

    From inception through December 31, 1995, the Company made payments under
consulting agreements with two directors, one of which is a limited partner of
MIF's general partner, and one shareholder. In 1995, the total expense under
these agreements was $129,000. In 1997, 1998 and 1999, the Company made payments
under a consulting agreement with a director who is a limited partner of MIF's
general partner totaling $81,000 per year.

    Beginning in September 1999, the Company subleased office space and provided
certain administrative services to a company whose principals include several
directors and shareholders. Total sublease rental received in 1999 was
approximately $66,000.

12.  SERIES B PREFERRED STOCK PURCHASE AGREEMENT

    On February 16, 2000, the Company and Amira Medical entered into a preferred
stock purchase agreement which is intended to provide funding to Integ at its
current operational level for the continued development of the LIFEGuide-TM-
System through 2000. Under the agreement, Amira will provide Integ with up to
$5.6 million in funding through the purchase of Integ Series B Preferred Stock.
Should the Company exercise its option to merge with Amira in the future, the
Series B will not participate in the merger considerations. The Series B
Preferred Stock is redeemable for cash or common stock, at the option of the
Company, in the case of a change in control or if the Company does not exercise
its option to merge with Amira.

    As part of the agreement, the Company will hold $1,500,000 of its existing
cash in reserve. As of September 30, 2000, the Company has raised $3.1 million
(unaudited) through the sale of 1,771,236 shares of Series B Preferred Stock.

                          AGREEMENT AND PLAN OF MERGER

    AGREEMENT AND PLAN OF MERGER (the "AGREEMENT"), dated as of October 3, 2000,
by and among Inverness Medical Technology, Inc., a Delaware corporation
("PARENT"), Terrier Acquisition Corp., a Delaware corporation and a wholly owned
subsidiary of Parent ("MERGERCO"), and Integ Incorporated, a Minnesota

                                    RECITALS

    WHEREAS, the respective Boards of Directors of Parent, MergerCo and the
Company have approved the merger of the Company with and into MergerCo (the

and the Minnesota Business Corporation Act (the "MBCA") and, upon the terms and
subject to the conditions set forth in this Agreement, holders of shares of
common stock, par value $.01 per share, of the Company (the "COMPANY COMMON
STOCK") issued and outstanding immediately prior to the Effective Time (as
defined herein) will be entitled, subject to the terms and conditions hereof, to
the right to receive shares of common stock, par value $.001 per share, of
Parent (the "PARENT COMMON STOCK");

    WHEREAS, the Board of Directors of the Company (the "COMPANY BOARD") has, in
light of and subject to the terms and conditions set forth herein,
(a) determined that (ii) the consideration to be paid for each share of Company
Common Stock in the Merger is fair to the shareholders of the Company, and
(ii) the Merger is in the best interests of the Company and its shareholders,
and (b) resolved to approve and adopt this Agreement and the transactions
contemplated or required by this Agreement, including the Merger (collectively,
the "TRANSACTIONS"), and to recommend approval and adoption by the shareholders
of the Company of this Agreement and the Transactions;

    WHEREAS, as a condition to the willingness of Parent and MergerCo to enter
into this Agreement, certain shareholders of the Company (the "VOTING AGREEMENT
SHAREHOLDERS") have entered into a Voting Agreement, dated as of the date
hereof, with Parent and MergerCo (the "VOTING AGREEMENT"), pursuant to which
each Voting Agreement Shareholder has agreed, among other things, to vote such
Voting Agreement Shareholder's shares of Company Common Stock in favor of the
approval of the Transactions, upon the terms and subject to the conditions set
forth in the Voting Agreement;

    WHEREAS, for federal income tax purposes, it is intended that the Merger
shall qualify as a reorganization under the provisions of Section 368 of the
Internal Revenue Code of 1986, as amended (the "CODE"), and this Agreement is
intended to be and is adopted as a plan of reorganization for purposes of
Sections 354, 361 and 368 of the Code; and

    WHEREAS, Parent, MergerCo and the Company desire to make certain
representations, warranties, covenants and agreements in connection with the
Transactions, and also to prescribe various conditions to the Transactions.

    NOW, THEREFORE, in consideration of the mutual covenants and agreements set
forth herein, Parent, MergerCo and the Company hereby agree as follows:

                                   ARTICLE I
                                   THE MERGER

    1.1  THE MERGER.  Subject to the terms and conditions of this Agreement, at
the Effective Time, the Company and MergerCo shall consummate the Merger
pursuant to which (a) the Company shall be merged with and into MergerCo and the
separate corporate existence of the Company shall thereupon cease, (b) MergerCo
shall be the successor or surviving corporation in the Merger (sometimes
hereinafter referred to as the "SURVIVING CORPORATION") and shall continue to be
governed by the laws of the State of Delaware and the DGCL, and (c) the separate
corporate existence of MergerCo with all its rights, privileges, immunities,
powers and franchises shall continue unaffected by the Merger. The

                                      A-1
<PAGE>
Merger shall have the effects specified in Section 302A.641 of the MBCA and
Section 259 of the DGCL. The Certificate of Incorporation of MergerCo, as in
effect at the Effective Time, shall be the Certificate of Incorporation of the
Surviving Corporation until thereafter amended as provided therein or by
applicable law. The Bylaws of MergerCo, as in effect at the Effective Time,
shall be the Bylaws of the Surviving Corporation until thereafter amended as
provided therein or by applicable law.

    1.2  EFFECTIVE TIME.  Subject to the provisions of this Agreement, as soon
as practicable after all of the conditions set forth in Article VIII shall have
been satisfied or, if permissible, waived, the parties will file articles or a
certificate of merger or other appropriate documents (the "ARTICLES OF MERGER")
executed in accordance with the relevant provisions of the MBCA and the DGCL and
will make all other filings or recordings required under the MBCA and the DGCL
in order to effect the Merger. The Merger will become effective at such time as
the Articles of Merger have been duly filed with the Secretary of State of the
State of Minnesota and the Secretary of State of the State of Delaware, or at
such subsequent date or time as MergerCo and the Company agree and specify in
the Articles of Merger (the time the Merger becomes effective being herein
referred to as the "EFFECTIVE TIME").

    1.3  CLOSING.  The closing of the Merger (the "CLOSING") shall take place at
such time and on a date to be specified by the parties, which shall be no later
than the second business day after satisfaction or waiver of all of the
conditions set forth in Article VIII hereof (the "CLOSING DATE"), at the offices
of Goodwin, Procter & Hoar LLP, Exchange Place, Boston, Massachusetts 02109,
unless another date or place is agreed to by the parties hereto.

    1.4  TAX CONSEQUENCES.  It is intended that the Merger shall constitute a
reorganization within the meaning of Section 368(a)(1)(A) and (A)(2)(D) of the
Code and that this Agreement shall constitute a "plan of reorganization" for
purposes of section 368 of the Code.

    1.5  RESERVATION OF RIGHT TO REVISE TRANSACTION.  Notwithstanding anything
to the contrary contained in this Agreement, Parent and MergerCo may, in their
sole discretion, at any time prior to the Effective Time, revise the method of
effecting the Merger; PROVIDED, HOWEVER, that (a) any breach of this Agreement
and any inability of the Company to satisfy any condition to the Merger set
forth in Section 8.3 of this Agreement arising solely as a result of such
revised method of effecting the Merger shall not be deemed a breach or a failure
of such condition to the consummation of the Merger, (b) such revised method of
effecting the Merger shall enable the Merger to continue to qualify as a
tax-free reorganization within the meaning of Section 368(a) of the Code and
(c) such revised method of effecting the Merger shall not (i) alter the Merger
Consideration (as defined in Section 3.1(b)) to be received by the holders of
Company Common Stock, (ii) cause the Company to incur additional costs or
(iii) expose the Company to additional liability arising solely as a result of
such revised method. The parties hereto agree that they will execute, and will
cause their respective direct and indirect subsidiaries, if any, to execute,
such agreements and documents and such amendments to this Agreement and any
related documents as shall be appropriate in order to reflect such revised
structure.

    2.1  DIRECTORS OF THE SURVIVING CORPORATION.  The directors of MergerCo
immediately prior to the Effective Time shall be the directors of the Surviving
Corporation immediately after the Effective Time until their successors shall

Bylaws of the Surviving Corporation.

                                  ARTICLE III
   EFFECT OF THE MERGER ON THE CAPITAL STOCK OF THE CONSTITUENT CORPORATIONS

    3.1  EFFECT ON CAPITAL STOCK.  As of the Effective Time, by virtue of the
Merger and without any action on the part of the holder of any shares of Company
Common Stock or any shares of capital stock of MergerCo:

        (a) Each issued and outstanding share of Company Common Stock owned by
    Parent, MergerCo or any other direct or indirect Parent Subsidiary
    immediately prior to the Effective Time, shall be canceled and retired and
    cease to exist without any conversion thereof and no payment or distribution
    shall be made with respect thereto.

        (b) Each share of Company Common Stock issued and outstanding
    immediately prior to the Effective Time, other than (i) those shares
    referred to in Section 3.1(a) and (ii) Dissenting Shares (as defined
    herein), shall be canceled and shall be converted automatically into and
    represent the right to receive such number of shares of Parent Common Stock
    as is equal to the Conversion Ratio (as defined herein) (collectively, the
    "MERGER CONSIDERATION").

        (c) The "CONVERSION RATIO" shall be the result obtained by dividing the
    Equivalent Parent Common Stock Amount by the number of shares of outstanding
    Company Common Stock immediately prior to the Effective Time plus the number
    of shares of Company Common Stock issuable upon the exercise of outstanding
    Company Options and Company Warrants (as defined herein). The "EQUIVALENT
    PARENT COMMON STOCK AMOUNT" shall be equal to the sum of: (i) the product of
    the Average Closing Price multiplied by 1,900,000, PLUS (ii) the number
    obtained by dividing (A) the aggregate exercise price of all Company Options
    and Company Warrants outstanding immediately prior to the Effective Time, by
    (B) the Average Closing Price of one share of Parent Common Stock. For
    purposes hereof; the "AVERAGE CLOSING PRICE" will mean the average of the
    closing sale prices of a share of Parent Common Stock on the American Stock
    Exchange ("AMEX") for the five (5) trading days immediately preceding the
    Effective Time.

        (d) Each share of common stock, par value $.001 per share, of MergerCo
    (the "MERGERCO COMMON STOCK") issued and outstanding immediately prior to
    the Effective Time shall remain outstanding and shall represent one validly
    issued, fully paid and non-assessable share of common stock, par value $.001
    per share, of the Surviving Corporation.

        (e) All shares of Company Common Stock, when converted as provided in
    Section 3.1(b), shall no longer be outstanding and shall automatically be
    canceled and retired and shall cease to exist, and each Certificate
    previously evidencing such shares shall thereafter represent only the right
    to receive shares of Parent Common Stock and cash in lieu of fractional
    shares of Parent Common Stock in accordance with Sections 3.1(b) and 4.1(e).
    The holders of Certificates previously evidencing shares of Company Common
    Stock outstanding immediately prior to the Effective Time shall cease to
    have any rights with respect to the Company Common Stock except as otherwise
    provided herein or by law and, upon the surrender of Certificates in
    accordance with the provisions of Article III hereof, shall only represent
    the right to receive for their shares of Company Common Stock, shares of
    Parent Common Stock and cash in lieu of fractional shares of Parent Common
    Stock in accordance with Sections 3.1(b) and 4.1(e).

    3.2  DISSENTERS' RIGHTS.

        (a) Notwithstanding Section 3.1 hereof, shares of the Company Common
    Stock issued and outstanding immediately prior to the Effective Time, if
    any, that are held of record or beneficially owned, on the record date for
    the Company shareholders' meeting, by a person who has properly exercised
    and preserved and perfected dissenters' rights with respect to such shares
    under Sections 302A.471 and 302A.473 of the MBCA and has not withdrawn or
    lost such rights ("DISSENTING SHARES") shall not be converted into or
    represent the right to receive Parent Common

                                      A-3
<PAGE>
    Stock for such shares, but instead shall be treated in accordance with
    Sections 302A.471 and 302A.473 of the MBCA unless and until such person
    effectively withdraws or loses such person's right to payment under
    Section 302A.473 of the MBCA (through failure to preserve or protect such
    right or otherwise). If, after the Effective Time, any such person shall
    effectively withdraw or lose such right, then each such Dissenting Share
    held of record or beneficially owned by such person will thereupon be
    treated as if it had been converted into, at the Effective Time, the right
    to receive Parent Common Stock, without interest.

        (b) Each person holding of record or beneficially owning Dissenting
    Shares who becomes entitled, under the provisions of Sections 302A.471 and
    302A.473 of the MBCA, to payment of the fair value of such Dissenting Shares
    shall receive payment therefor (plus interest determined in accordance with
    Section 302A.473 of the MBCA) from the Surviving Corporation.

        (c) The Company shall give Parent prompt written notice upon receipt by
    the Company at any time before the Effective Time of any notice of intent to
    demand the fair value of any shares of Company Common Stock under
    Section 302A.473 of the MBCA and any withdrawal of any such notice. The
    Company will not, except with the prior written consent of Parent,
    negotiate, voluntarily make any payment with respect to, or settle or offer
    to settle, any such demand at any time before the Effective Time.

    3.3  COMPANY STOCK OPTIONS AND RELATED MATTERS.

        (a) Each option (collectively, the "COMPANY OPTIONS") granted under the
    Company's 1990 Incentive and Stock Option Plan (the "1990 PLAN"), the 1991
    Incentive and Stock Option Plan (the "1991 PLAN"), the 1994 Long-Term
    Incentive and Stock Option Plan (as revised and restated, the "1994 PLAN")
    and the 1996 Directors' Stock Option Plan (the "1996 PLAN," and the 1996
    Plan together with the 1990 Plan, the 1991 Plan and the 1994 Plan, the
    "COMPANY STOCK OPTION PLANS"), which is outstanding (whether or not then
    exercisable) as of immediately prior to the Effective Time and which has not
    been exercised or canceled prior thereto, shall, at the Effective Time, be
    assumed by Parent, subject to the provisions of this Section 3.3 (the
    "ASSUMED OPTIONS"). The Assumed Options shall not terminate in connection
    with the Merger and shall continue to have, and be subject to, the same
    terms and conditions as set forth in the Company Stock Option Plans and
    agreements (as in effect immediately prior to the Effective Time) pursuant
    to which the Company Options were granted, provided that (i) all references
    to the Company shall be deemed to be references to Parent and all references
    to shares of Company Common Stock shall be deemed to be references to shares
    of Parent Common Stock, (ii) each Company Option shall be exercisable for
    that number of whole shares of Parent Common Stock equal to the product of
    the number of shares of Company Common Stock covered by such Company Option
    immediately prior to the Effective Time multiplied by the Conversion Ratio
    and rounded down to the nearest whole number of shares of Parent Common
    Stock and (iii) the exercise price per share of Company Common Stock under
    such Company Option shall be equal to the exercise price per share of
    Company Common Stock under the Company Option divided by the Conversion
    Ratio and rounded up to the nearest cent. Parent shall (A) reserve for
    issuance the number of shares of Parent Common Stock that will become
    issuable upon the exercise of such Assumed Options pursuant to this
    Section 3.3, (B) promptly after the Effective Time issue to each holder of
    an Company Option a document evidencing the assumption by Parent of the
    Company's obligations with respect thereto under this Section 3.3, and
    (C) as soon as practicable after the Effective Time, but in no event less
    than ten (10) business days after the Effective Time, use its best efforts
    to cause to be filed a registration statement or amend an existing
    registration statement on an appropriate form under the Securities Act of
    1933, as amended (the "SECURITIES ACT"), relating to the Company Stock
    Option Plans then in effect and covering the shares of Parent Common Stock
    issuable upon exercise of the Assumed Options.

                                      A-4
<PAGE>
        (b) The adjustments provided in this Section 3.3 with respect to any
    Company Options that are "incentive stock options" as defined in
    Section 422 of the Code, shall be and are intended to be effected in a
    manner which is consistent with Section 424(a) of the Code.

        (c) The Company's 1997 Employee Stock Purchase Plan, as amended (the
    "COMPANY STOCK PURCHASE PLAN"), shall terminate in accordance with its terms
    as of the date of the shareholders meeting of the Company, and each
    participant in the Company Stock Purchase Plan as of such date shall be
    deemed to have exercised his or her right to purchase under the Company
    Stock Purchase Plan on such date and shall acquire from the Company
    (i) such number of whole shares of Company Common Stock as his or her
    accumulated payroll deductions on such date will purchase at the price
    specified in the Company Stock Purchase Plan with the entire credit balance
    in such participant's Stock Purchase Account (as defined in the Company
    Stock Purchase Plan) (treating the last business day prior to the date of
    the shareholders meeting of the Company as the date of purchase for all
    purposes of the Company Stock Purchase Plan) and (ii) cash in the amount of
    any remaining balance in such participant's account; PROVIDED, HOWEVER, that
    any participant that has given notice to the Company in accordance with the
    Company Stock Purchase Plan that such participant requests the distribution
    of his or her entire credit balance in cash shall receive cash in the amount
    of the balance in such participant's Stock Purchase Account.

    3.4  COMPANY WARRANTS.  At the Effective Time, Parent shall assume each
Company Warrant (as defined in Section 5.3(a)) hereof in accordance with the
terms (as in effect as of the date hereof) of such Company Warrant. From and
after the Effective Time, (a) each Company Warrant assumed by Parent may be
exercised solely for shares of Parent Common Stock, (b) the number of shares of
Parent Common Stock subject to each Company Warrant shall be equal to the number
of shares of Company Common Stock subject to such Company Warrant immediately
prior to the Effective Time multiplied by the Conversion Ratio, rounding to the
nearest whole share, (c) the per share exercise price under each such Company
Warrant shall be equal to the per share exercise price under such Company
Warrant divided by the Conversion Ratio, rounding to the nearest cent and
(d) any restriction on the exercise of any Company Warrant shall continue in
full force and effect and the term, exercisability and other provisions of such
Company Warrant shall otherwise remain unchanged. The Company shall take all
action that may be necessary (under the Company Warrants and otherwise) to
effectuate the provisions of this Section 3.4 and to ensure that, from and after
the Effective Time, holders of the Company Warrants have no rights with respect
thereto other than those specifically provided therein.

                                   ARTICLE IV
                               PAYMENT OF SHARES

    4.1  PAYMENT FOR SHARES OF COMPANY COMMON STOCK.

        (a) At or prior to the Effective Time, Parent shall deposit, or
    otherwise take all steps necessary to cause to be deposited, with Boston
    EquiServe (the "EXCHANGE AGENT") certificates representing the shares of
    Parent Common Stock and the cash in lieu of fractional shares (such cash and
    certificates for shares of Parent Common Stock being hereinafter referred to
    as the "EXCHANGE FUND") to be issued pursuant to Section 3.1 and paid
    pursuant to this Article IV in exchange for outstanding shares of Company
    Common Stock.

                                      A-5
<PAGE>
        (b) Promptly after the Effective Time, Parent shall cause the Exchange
    Agent to mail to each holder of record of a Certificate or Certificates
    (i) a letter of transmittal which shall specify that delivery shall be
    effected, and risk of loss and title to the Certificates shall pass, only
    upon delivery of the Certificates to the Exchange Agent and shall be in such
    form and have such other provisions as Parent may reasonably specify and
    (ii) instructions for use in effecting the surrender of the Certificates in
    exchange for certificates representing shares of Parent Common Stock and
    cash in lieu of fractional shares of Parent Common Stock. Upon surrender of
    a Certificate for cancellation to the Exchange Agent together with such
    letter of transmittal, duly executed and completed in accordance with the
    instructions thereto, the holder of such Certificate shall be entitled to
    receive in exchange therefor (A) a certificate representing the number of
    whole shares of Parent Common Stock to which such holder shall be entitled,
    and (B) a check representing the amount of cash in lieu of fractional
    shares, if any, plus the amount of any dividends, or distributions, if any,
    pursuant to paragraph (c) below, after giving effect to any required
    withholding tax, and the Certificate so surrendered shall forthwith be
    canceled. No interest will be paid or accrued on the cash in lieu of
    fractional shares or on the dividend or distribution, if any, payable to
    holders of Certificates pursuant to this Section 4.1. In the event of a
    transfer of ownership of Company Common Stock which is not registered in the
    transfer records of the Company, a Certificate representing the proper
    number of shares of Parent Common Stock, together with a check for the cash
    to be paid in lieu of fractional shares of Parent Common Stock plus, to the
    extent applicable, the amount of any dividend or distribution, if any,
    payable pursuant to paragraph (c) below, may be issued to such a transferee
    if the Certificate representing shares of such Company Common Stock is
    presented to the Exchange Agent, accompanied by all documents required to
    evidence and effect such transfer and to evidence that any applicable stock
    transfer taxes have been paid.

        (c) Notwithstanding any other provisions of this Agreement, no dividends
    or other distributions on Parent Common Stock shall be paid with respect to
    any shares of Company Common Stock represented by a Certificate until such
    Certificate is surrendered for exchange as provided herein; PROVIDED,
    HOWEVER, that subject to the effect of applicable laws, following surrender
    of any such Certificate, there shall be paid to the holder of the
    certificates representing whole shares of Parent Common Stock issued in
    exchange therefor, without interest, (i) at the time of such surrender, the
    amount of dividends or other distributions with a record date after the
    Effective Time theretofore payable with respect to such whole shares of
    Parent Common Stock and not paid, less the amount of any withholding taxes
    which may be required thereon, and (ii) at the appropriate payment date, the
    amount of dividends or other distributions with a record date after the
    Effective Time but prior to surrender and a payment date subsequent to
    surrender payable with respect to such whole shares of Parent Common Stock,
    less the amount of any withholding taxes which may be required thereon.

        (d) At and after the Effective Time, there shall be no transfers on the
    stock transfer books of the Company of the shares of Company Common Stock
    which were outstanding immediately prior to the Effective Time. If, after
    the Effective Time, Certificates are presented to the Surviving Corporation,
    they shall be canceled and exchanged for certificates for shares of Parent
    Common Stock and cash in lieu of fractional shares, if any, in accordance
    with this Section 4.1.

        (e) No fractional shares of Parent Common Stock shall be issued pursuant
    hereto. In lieu of the issuance of any fractional share of Parent Common
    Stock pursuant to Section 3.1(b), each holder of Company Common Stock upon
    surrender of a Certificate for exchange shall be paid an amount in cash
    (without interest), rounded to the nearest cent, determined by multiplying
    (i) the average per share closing price of a share of Parent Common Stock as
    reported on the AMEX over the five (5) trading days immediately preceding
    the date of the Closing by (ii) the fraction of

                                      A-6

    a share of Parent Common Stock which such holder would otherwise be entitled
    to receive under this Section 4.1.

        (f) Any portion of the Exchange Fund (including the proceeds of any
    investments thereof and any shares of Parent Common Stock) that remains
    unclaimed by the former shareholders of the Company one year after the
    Effective Time shall be delivered to the Surviving Corporation. Any former
    shareholders of the Company who have not theretofore complied with this
    Article III shall thereafter look only to the Surviving Corporation for
    payment of their shares of Parent Common Stock and cash in lieu of
    fractional shares (plus dividends and distributions to the extent set forth
    in Section 4.1(c), if any), as determined pursuant to this Agreement,
    without any interest thereon. None of Parent, MergerCo, the Company, the
    Exchange Agent or any other person shall be liable to any former holder of
    shares of Company Common Stock for any amount properly delivered to a public
    official pursuant to applicable abandoned property, escheat or similar laws.
    In the event any Certificate shall have been lost, stolen or destroyed, upon
    the making of an affidavit of that fact by the person claiming such
    Certificate to be lost, stolen or destroyed and, if required by the
    Surviving Corporation, the posting by such person of a bond in such
    reasonable amount as the Surviving Corporation may direct as indemnity
    against any claim that may be made against it with respect to such
    Certificate, the Exchange Agent or the Surviving Corporation will issue in
    exchange for such lost, stolen or destroyed Certificate the shares of Parent
    Common Stock and cash in lieu of fractional shares (plus, to the extent
    applicable, dividends and distributions payable pursuant to
    Section 4.1(c)).

                                   ARTICLE V
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

    Except as set forth in the disclosure letter delivered at or prior to the
execution hereof to Parent, which shall refer to the relevant Sections of this
Agreement (the "COMPANY DISCLOSURE SCHEDULE"), the Company represents and
warrants to Parent and MergerCo as follows:

    5.1  EXISTENCE; GOOD STANDING; AUTHORITY.  The Company is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Minnesota. Except as set forth in Section 5.1 of the Company Disclosure
Schedule, the Company is duly licensed or qualified to do business as a foreign
corporation and is in good standing under the laws of any other state of the
United States in which the character of the properties owned or leased by it
therein or in which the transaction of its business makes such qualification
necessary, except where the failure to be so licensed or qualified would not
reasonably be expected to have a material adverse effect on the current
business, results of operations or financial condition of the Company taken as a
whole (a "COMPANY MATERIAL ADVERSE EFFECT"). The Company has all requisite
corporate power and authority to own, operate, lease and encumber its properties
and carry on its business as now conducted.

    5.2  AUTHORIZATION, VALIDITY AND EFFECT OF AGREEMENTS.  The Company has the
requisite power and authority to enter into the Transactions and to execute and
deliver this Agreement. The Company Board has approved this Agreement, the
Merger and the other Transactions and has resolved to recommend that the holders
of Company Common Stock adopt and approve this Agreement at the shareholders'
meeting of the Company to be held in accordance with the provisions of
Section 7.3. In connection with the foregoing, the Company Board has taken such
actions and votes as are necessary on its part to render the provisions of
Section 302A.673 of the MBCA and all other applicable takeover statutes
inapplicable to this Agreement, the Merger and the other Transactions. Subject
only to the approval of this Agreement by the holders of a majority of the
outstanding shares of Company Common Stock, the execution by the Company of this
Agreement and the consummation of the Transactions have been duly authorized by
all requisite corporate action on the part of the Company. As of the date
hereof, all of the directors and executive officers of the Company have
indicated that they presently intend to vote all shares of Company Common Stock
that they own to approve this

                                      A-7

Agreement and the Transactions at the shareholders' meeting of the Company to be
held in accordance with the provisions of Section 8.1. This Agreement, assuming
due and valid authorization, execution and delivery thereof by Parent and
MergerCo, constitutes a valid and legally binding obligation of the Company,
enforceable against the Company in accordance with its terms, subject to
applicable bankruptcy, insolvency, moratorium or other similar laws relating to
creditors' rights and general principles of equity.

    5.6  NO VIOLATION; CONSENTS.  Except as set forth in Section 5.6 of the
Company Disclosure Schedule, neither the execution and delivery by the Company
of this Agreement nor consummation by the Company of the Transactions in
accordance with the terms hereof, will conflict with or result in a breach of
any provisions of the Company Charter or the Company Bylaws or the Company
Rights Agreement (as defined in Section 5.26). Except as set forth in
Section 5.6 of the Company Disclosure Schedule, the execution and delivery by
the Company of this Agreement and consummation by the Company of the
Transactions in accordance with the terms hereof will not violate, or conflict
with, or result in a breach of any provision of, or constitute a default (or an
event which, with notice or lapse of time or both, would constitute a default)
under, or result in the termination or in a right of termination or cancellation
of, or accelerate the performance required by, or result in the creation of any
lien, security interest, charge or encumbrance ("Lien") upon any of the
properties of the Company under, or result in being declared void, voidable or
without further binding effect, any of the terms, conditions or provisions of
(a) any note, bond, mortgage, indenture or deed of trust or (b) any license,
franchise, permit, lease, contract, agreement or other instrument, commitment or
obligation to which the Company is a party, or by which the Company or any of
its properties is bound, except as otherwise would not have a Company Material
Adverse Effect. Other than the filings provided for in Article I of this
Agreement, the Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT"),
the Securities Act or applicable state securities and "Blue Sky" laws
(collectively, the "REGULATORY FILINGS"), the execution and delivery of this
Agreement by the Company does not, and the performance of this Agreement by the
Company and consummation of the Transactions does not, require any consent,
approval or authorization of, or declaration, filing or registration with, any
governmental or regulatory authority, except where the failure to obtain any
such consent, approval or authorization of, or declaration, filing or
registration with, any governmental or regulatory authority would not have a
Company Material Adverse Effect.

    5.7  SEC DOCUMENTS.  The Company has filed all required forms, reports and
documents with the Securities and Exchange Commission (the "SEC") since July 1,
1997 (collectively, the "COMPANY SEC REPORTS"), all of which were prepared in
all material respects in accordance with the applicable requirements of the
Exchange Act, the Securities Act and the rules and regulations promulgated
thereunder (the "SECURITIES LAWS"). As of their respective dates, the Company
SEC Reports (a) complied as to form in all material respects with the applicable
requirements of the Securities Laws and (b) did not contain any untrue statement
of a material fact or omit to state a material fact required to be stated
therein or necessary to make the statements made therein, in the light of the
circumstances under which they were made, not misleading. The representation in
clause (b) of the preceding sentence does not apply to any misstatement or
omission in any Company SEC Report filed prior to the date of this Agreement
which was superseded by and corrected in a subsequent Company SEC Report filed
prior to the date of this Agreement. Each of the consolidated balance sheets of
the Company included in or incorporated by reference into the Company SEC
Reports (including the related notes and schedules) fairly presents in all
material respects the consolidated financial position of the Company as of its
date and each of the consolidated statements of income, retained earnings

                                      A-9
<PAGE>
and cash flows of the Company included in or incorporated by reference into the
Company SEC Reports (including any related notes and schedules) fairly presents
in all material respects the results of operations, retained earnings or cash
flows, as the case may be, of the Company for the periods set forth therein
(subject, in the case of unaudited statements, to normal year-end audit
adjustments which would not be material in amount or effect), in each case in
accordance with generally accepted accounting principles consistently applied
during the periods involved, except as may be noted therein and except, in the
case of the unaudited statements, as permitted by Form 10-Q pursuant to
Section 13 or 15(d) of the Exchange Act.

    5.8  LITIGATION.  Except as set forth in Section 5.8 of the Company
Disclosure Schedule, there is no litigation, suit, action or proceeding pending
or, to the knowledge of the Company, threatened against the Company, as to which
there is a reasonable likelihood of an adverse determination and which, if
adversely determined, individually or in the aggregate with all such other
litigation, suits, actions or proceedings, would (a) have a Company Material
Adverse Effect, (b) materially and adversely affect the Company's ability to
perform its obligations under this Agreement or (c) prevent the consummation of
any of the Transactions.

    5.9  ABSENCE OF CERTAIN CHANGES.  Except as disclosed in the Company SEC
Reports filed and publicly available prior to the date of this Agreement, the
Company has conducted its business only in the ordinary course of business, and
there has not been: (a) as of the date hereof, any declaration, setting aside or
payment of any dividend or other distribution with respect to Company Common
Stock; (b) any material commitment, contractual obligation (including, without
limitation, any management or franchise agreement, any lease (capital or
otherwise) or any letter of intent), borrowing, liability, guaranty, capital
expenditure or transaction (each, a "COMMITMENT") entered into by the Company
outside of the ordinary course of business except for Commitments for expenses
of attorneys, accountants and investment bankers incurred in connection with the
Transactions; or (c) any material change in the Company's accounting principles,
practices or methods.

    5.10  TAXES.

        (a) The Company has timely filed all Tax Returns (as defined herein)
    required to be filed by it (after giving effect to any filing extension
    granted by a Governmental Entity (as defined in Section 5.15)), and all such
    Tax Returns were correct and complete in all respects, except where a
    failure to file a Tax Return or the failure of any Tax Return to be correct
    and complete would not have a Company Material Adverse Effect. The Company
    has paid all Taxes (as defined herein) required to be paid, collected or
    withheld, except for Taxes for which adequate reserves in the financial
    statements contained in the Company's most recent Quarterly Report on
    Form 10-Q have been established in accordance with United States GAAP and
    except where the failure to pay such Taxes would not have a Company Material
    Adverse Effect. Except as set forth in Section 5.10(a) of the Company
    Disclosure Schedule, the most recent audited financial statements contained
    in the Company's Annual Report on Form 10-K for the fiscal year ended
    December 31, 1999 reflect an adequate reserve for all material Taxes payable
    by the Company for all taxable periods and portions thereof through the date
    of such financial statements in accordance with GAAP. Except as set forth in
    Section 5.10(a) of the Company Disclosure Schedule, no deficiencies for any
    Taxes have been proposed, asserted or assessed against the Company, and no
    requests for waivers of the time to assess any such Taxes are pending or in
    effect. The Company is not currently the beneficiary of any extension of
    time within which to file any material Tax Return or within which to pay any
    material amounts of Taxes. No claim has ever been made by an authority in a
    jurisdiction where the Company does not file Tax Returns that it is or may
    be subject to taxation by that jurisdiction. Section 5.10(a) of the Company
    Disclosure Schedule lists all (i) Tax sharing agreements and (ii) all liens
    for material amounts of Taxes on the assets of the Company except for
    statutory liens for current Taxes yet due and payable.

<PAGE>
        (b) The Company has withheld and paid all Taxes required to have been
    withheld and paid in connection with amounts paid or owing to any employee,
    independent contractor, creditor, shareholder or other third party.

        (c) No director or officer (or employee responsible for Tax matters) of
    the Company expects any authority to assess any additional Taxes for any
    period for which Tax Returns have been filed. There is no dispute or claim
    concerning any Tax liability of any of the Company either (i) claimed or
    raised by any authority in writing or (ii) as to which any of the directors
    and officers (and employees responsible for Tax matters) of the Company has
    knowledge based upon personal contact with any agent of such authority.
    Section 5.10(c) of the Company Disclosure Schedule lists all federal, state,
    local and foreign income Tax Returns filed with respect to the Company for
    taxable periods ended on or after December 31, 1995, indicates those Tax
    Returns that have been audited, and indicates those Tax Returns that
    currently are the subject of audit. The Company has delivered to Parent
    correct and complete copies of all federal income Tax Returns, examination
    reports and statements of deficiencies assessed against or agreed to by the
    Company since December 31, 1995.

        (d) The Company has not filed a consent under Section 341(f) of the
    Code, concerning collapsible corporations. Except as set forth in
    Section 5.10(c) of the Company Disclosure Schedule, the Company has not made
    any payments, is not obligated to make any payments, and is not a party to
    any agreement that under certain circumstances could obligate it to make any
    payments that will not be deductible under Code Section 280G. The Company
    has not been a United States real property holding corporation within the
    meaning of Code Section 897(c)(2) during the applicable period specified in
    Code Section 897(c)(1)(A)(ii). The Company (i) has not been a member of an
    affiliated group filing a consolidated federal income Tax Return (other than
    a group the common parent of which was the Company) or (ii) has any
    liability for the Taxes of any person (other than Taxes of the Company)
    under Treasury Regulations Section 1.1502-6 (or any similar provision of
    state, local or foreign law), as a transferee or successor, by contract or
    otherwise.

        (e) For purposes of this Agreement, "TAXES" means all federal, state,
    local and foreign income, property, sales, franchise, employment, excise and
    other taxes, tariffs or governmental charges of any nature whatsoever,
    together with any interest, penalties or additions to Tax with respect
    thereto.

        (f) For purposes of this Agreement, "TAX RETURNS" means all reports,
    returns, declarations, statements or other information required to be
    supplied to a taxing authority in connection with Taxes.

    true, complete and correct in all material respects, have been maintained in
    accordance with good business practices, and are accurately reflected in all
    material respects in the financial statements included in the Company SEC
    Reports.

    available to Parent, contain in all material respects accurate records of
    all meetings and accurately reflect in all material respects all other
    corporate action of the shareholders and directors and any committees of the

<PAGE>
        (b) Section 5.12(b) of the Company Disclosure Schedule contains a list
    of all leases, subleases and other occupancy agreements, including all
    amendments, extensions and other modifications (the "LEASES") for real
    property (the "LEASED REAL PROPERTY") to which the Company is the "tenant,"
    "subtenant" or other lessee party. The Company has a good and valid
    leasehold interest in and to all of the Leased Real Property, subject to no
    Liens, encroachments, encumbrances or other defects in title, except as
    described in Section 5.12(b) of the Company Disclosure Schedule and except
    for such Liens, encroachments, encumbrances or other defects in title which
    could not individually or in the aggregate have a Material Adverse Effect.
    Each Lease is in full force and effect and is enforceable in accordance with
    its terms. There exists no material default or condition which, with the
    giving of notice, the passage of time or both, could become a material
    default of the Company under any Lease. The Company has previously delivered
    to Parent true and complete copies of all the Leases. Except as described in
    Section 5.12(b) of the Company Disclosure Schedule, no consent, waiver,
    approval or authorization is required from the landlord under any Lease as a
    result of the execution of this Agreement or the consummation of the
    transactions contemplated hereby.

        (c) The Leased Real Property constitutes all of the real property owned,
    leased, occupied or used by the Company in connection with the business of
    the Company. Except as set forth in Section 5.12(c) of the Company
    Disclosure Schedule, other than the Company, there are no parties in
    possession or parties having any current or future right to occupy any of
    the Leased Real Property during the term of any Lease regarding such Leased
    Real Property. The Leased Real Property is sufficient and appropriate for
    the conduct of the business of the Company as it is currently conducted or
    as it is currently proposed to be conducted. To the knowledge of the Company
    (i) the Leased Real Property conforms in all material respects to all
    applicable building, zoning and other laws, ordinances, rules and
    regulations, (ii) all Licenses and other approvals necessary to the current
    occupancy and use of the Leased Real Property have been obtained, are in
    full force and effect and have not been violated, and (iii) there exists no
    violation of any covenant, condition, restriction, easement, agreement or
    order affecting any portion of the Leased Real Property which individually
    or in the aggregate could cause a Material Adverse Effect. To the knowledge
    of the Company, there is no pending or threatened condemnation proceeding
    affecting any portion of the Leased Real Property.

    5.13  INTELLECTUAL PROPERTY.

        (a) OWNERSHIP OF INTELLECTUAL PROPERTY ASSETS. Except as set forth in
    Section 5.13(a) of the Company Disclosure Schedule, the Company is the
    exclusive owner of, and has good, valid and marketable title to all of the

    encumbrances or agreements, and has the right to use without payment to a
    third party all of the Intellectual Property Assets used in the business or

    Company and/or its officers, employees and consultants to the effect that
    the Company's right, title and interest in and to the Intellectual Property
    Assets is invalid or unenforceable by the Company, nor is the Company aware
    of any information which would adversely affect the validity or
    enforceability of any of the Patents (as defined herein), Marks (as defined
    herein) or Copyrights (as defined herein) of the Intellectual Property
    Assets. All former and current employees, consultants and contractors of the
    Company have executed written instruments with the Company that assign to
    the Company all rights to any inventions, improvements, discoveries,
    writings or information relating to the business of the Company. No employee
    of the Company has entered into any agreement that restricts or limits in
    any way the scope or type of work in which the employee may be engaged or
    requires the employee to transfer, assign or disclose information concerning
    his work to anyone other than the Company.

    5.18  EMPLOYEE BENEFIT PROGRAMS.

        (a) Section 5.18 of the Company Disclosure Schedule sets forth a list of
    every Employee Program that has been maintained by the Company or an
    Affiliate at any time during the five-year period ending on the Closing
    Date.

        (b) Each Employee Program which has ever been maintained by the Company
    or an Affiliate and which has been intended to qualify under Section 401(a)
    or 501(c)(9) of the Code has received a favorable determination or approval
    letter from the Internal Revenue Service ("IRS") regarding its qualification
    under such section and has, in fact, been qualified under the applicable
    section of the Code from the effective date of such Employee Program through
    and including the Closing Date (or, if earlier, the date that all of such
    Employee Program's assets were distributed). No event or omission has
    occurred which would cause any Employee Program to lose its qualification or
    otherwise fail to satisfy the relevant requirements to provide tax-favored
    benefits under the applicable Code Section (including without limitation
    Code Sections 105, 125, 401(a) and 501(c)(9)). Each asset held under any
    such Employee Program may be liquidated or terminated without the imposition
    of any redemption fee, surrender charge or comparable liability. No partial
    termination (within the meaning of Section 411(d)(3) of the Code) has
    occurred with respect to any Employee Program.

        (c) Neither the Company nor any Affiliate knows, nor should any of them
    reasonably know, of any failure of any party to comply with any laws
    applicable with respect to the Employee Programs that have ever been
    maintained by the Company or any Affiliate. With respect to any Employee
    Program ever maintained by the Company or any Affiliate, there has been no
    (i) "prohibited transaction," as defined in Section 406 of the Employee
    Retirement Income Security Act of 1974, as amended ("ERISA") or Code
    Section 4975, (ii) failure to comply with any provision of ERISA, other
    applicable law, or any agreement, or (iii) non-deductible contribution,
    which, in the case of any of (i), (ii), or (iii), could subject the Company
    or any Affiliate to liability either directly or indirectly (including,
    without limitation, through any obligation of indemnification or
    contribution) for any damages, penalties, or taxes, or any other loss or
    expense. No litigation or governmental administrative proceeding (or
    investigation) or other proceeding (other than those relating to routine
    claims for benefits) is pending or threatened with respect to any such
    Employee Program. All payments and/or contributions required to have been
    made (under the provisions of any agreements or other governing documents or
    applicable law) with respect to all Employee Programs ever maintained by the
    Company or any Affiliate, for all periods prior to the Closing Date, either
    have been made or have been accrued (and all such unpaid but accrued amounts
    are described in Section 5.18 of the Company Disclosure Schedule.

        (d) Neither the Company nor any Affiliate has ever maintained an
    Employee Program subject to Title IV of ERISA. Neither the Company nor any
    Affiliate has ever contributed to or been obligated to contribute to a
    Multiemployer Plan and neither the Company nor any Affiliate has ever had
    any collectively bargained employees. Except as set forth in Section 5.18 of
    the Company Disclosure Schedule, none of the Employee Programs ever
    maintained by the Company or any Affiliate has ever provided health care or
    any other non-pension benefits to any employees after their employment is
    terminated (other than as required by Part 6 of Subtitle B of Title I of
    ERISA) or has ever promised to provide such post-termination benefits.

        (e) With respect to each Employee Program maintained by the Company
    within the five (5) years preceding the Closing Date, complete and correct
    copies of the following documents (if applicable to such Employee Program)
    have previously been delivered to Parent or its representatives: (i) all
    documents embodying or governing such Employee Program, and any funding
    medium for the Employee Program (including, without limitation, trust
    agreements) as they may have been amended to the date hereof; (ii) the most
    recent IRS determination or

                                      A-18
<PAGE>
    approval letter with respect to such Employee Program under Code
    Section 401(a) or 501(c)(9), and any applications for determination or
    approval subsequently filed with the IRS; (iii) the five (5) most recently
    filed IRS Forms 5500, with all applicable schedules and accountants'
    opinions attached thereto; (iv) the summary plan description for such
    Employee Program (or other descriptions of such Employee Program provided to
    employees) and all modifications thereto; (v) any insurance policy
    (including any fiduciary liability insurance policy or fidelity bond)
    related to such Employee Program; (vi) any registration statement or other
    filing made pursuant to any federal or state securities law and (vii) all
    correspondence to and from any state or federal agency within the last five
    (5) years with respect to such Employee Program.

        (f) Each Employee Program required to be listed in Section 5.18 of the
    Company Disclosure Schedule may be amended, terminated, or otherwise
    modified by the Company to the greatest extent permitted by applicable law,
    including the elimination of any and all future benefit accruals under any
    Employee Program and no employee communications or provision of any Employee
    Program document has failed to effectively reserve the right of the Company
    or the Affiliate to so amend, terminate or otherwise modify such Employee
    Program.

        (g) Each Employee Program ever maintained by the Company (including each
    non-qualified deferred compensation arrangement) has been maintained in
    material compliance with all applicable requirements of federal and state
    securities laws including (without limitation, if applicable) the
    requirements that the offering of interests in such Employee Program be
    registered under the Securities Act and/or state "Blue Sky" laws.

        (h) Each Employee Program ever maintained by the Company or an Affiliate
    has complied with the applicable notification and other applicable
    requirements of the Consolidated Omnibus Budget Reconciliation Act of 1985,
    Health Insurance Portability and Accountability Act of 1996, the Newborns'
    and Mothers' Health Protection Act of 1996, the Mental Health Parity Act of
    1996, and the Women's Health and Cancer Rights Act of 1998.

           (i) "EMPLOYEE PROGRAM" means (A) all employee benefit plans within
       the meaning of ERISA Section 3(3), including, but not limited to,
       multiple employer welfare arrangements (within the meaning of ERISA

       contributes and employee benefit plans (such as foreign or excess benefit
       plans) which are not subject to ERISA; (B) all stock option plans, stock
       purchase plans, bonus or incentive award plans, severance pay policies or
       agreements, deferred compensation agreements, supplemental income
       arrangements, vacation plans, and all other employee benefit plans,
       agreements, and arrangements (including any informal arrangements) not

       intended to comply with Code Section 120, 125, 127, 129 or 137; and
       (C) all plans or arrangements providing compensation to employee and
       non-employee directors. In the case of an Employee Program funded through
       a trust described in Code Section 401(a) or an organization described in
       Code Section 501(c)(9), or any other funding vehicle, each reference to
       such Employee Program shall include a reference to such trust,
       organization or other vehicle.

           (ii) An entity "MAINTAINS" an Employee Program if such entity
       sponsors, contributes to, or provides benefits under or through such
       Employee Program, or has any obligation (by agreement or under applicable
       law) to contribute to or provide benefits under or through such Employee
       Program, or if such Employee Program provides benefits to or otherwise
       covers employees of such entity (or their spouses, dependents, or
       beneficiaries).

           (iii) An entity is an "AFFILIATE" of the Company if it would have
       ever been considered a single employer with the Company under ERISA
       Section 4001(b) or part of the same "controlled group" as the Company for
       purposes of ERISA Section 302(d)(8)(C).

        (a) Except as set forth in Section 5.19 of the Company Disclosure
    Schedule, (i) there is no labor strike, picketing of any nature, material

    Company's employees. The Company is, and at all time since November 6, 1986
    has been, in compliance with the requirements of the Immigration Reform
    Control Act of 1986.

        (c) Except as set forth in Section 5.19 of the Company Disclosure
    Schedule, the Company does not employ or use any independent contractors,
    temporary employees, leased employees or any other servants or agents
    compensated other than through reportable wages paid by the

                                      A-20
<PAGE>
    Company (collectively, "CONTINGENT WORKERS"). To the extent that the Company
    employs or uses Contingent Workers, it has properly classified and treated
    them in accordance with applicable laws and for purposes of all benefit
    plans and perquisites.

    5.20  VOTE REQUIRED.  The affirmative vote of the holders of a majority of
the shares of Company Common Stock outstanding on the record date for the
Company shareholders' meeting is the only vote of the holders of any class or
series of the Company's capital stock necessary to approve and consummate this
Agreement, the Merger and the other transactions contemplated by this Agreement.

    5.21  NO BROKERS.  The Company has not entered into any contract,
arrangement or understanding with any person or firm that may result in the
obligation of such entity or Parent to pay any finder's fees, brokerage or
agent's commissions or other like payments in connection with the negotiations
leading to this Agreement or consummation of the Transactions, except that the
Company has retained U.S. Bancorp Piper Jaffray Inc. ("PIPER JAFFRAY") as its
financial advisor in connection with the Transactions. Other than the foregoing
arrangements and those referred to in Section 6.6 hereof, the Company is not
aware of any claim for payment of any finder's fees, brokerage or agent's
commissions or other like payments in connection with the negotiations leading
to this Agreement or consummation of the Transactions.

    5.22  OPINION OF FINANCIAL ADVISOR.  The Company has received the opinion of
Piper Jaffray to the effect that, as of the date hereof, the Merger
Consideration is fair to the holders of Company Common Stock from a financial
point of view.

    5.23  INSURANCE.  The Company is covered by insurance in scope and amount
customary and reasonable for the business in which it is engaged. The Company is
not in material breach or default (including with respect to the payment of
premiums or the giving of notices) under any insurance policy to which it is a
party, and no event has occurred which, with notice or the lapse of time, would
constitute such a material breach or default by the Company or would permit
termination, modification or acceleration, under such policies; and the Company
has not received any notice from the insurer disclaiming coverage or reserving
rights with respect to any material claim or any such policy in general.

    5.24  INTENTIONALLY OMITTED.

    5.25  REORGANIZATION.  As of the date of this Agreement, the Company has no
reason to believe that the Merger will not qualify as a "reorganization" within
the meaning of Section 368(a) of the Code.

    5.26  COMPANY RIGHTS AGREEMENT.  The Company Rights Agreement, dated as of
November 26, 1996, as amended (the "COMPANY RIGHTS AGREEMENT"), has been amended
to provide that the execution, delivery and performance of this Agreement and
the Voting Agreement and the consummation of the Merger will not cause any
change, effect or result under the Company Rights Agreement, which is adverse to
the interests of Parent or any of its affiliates, including without limitation,
causing Parent or any of its affiliates to become an "Acquiring Person" (as
defined therein) under the Company Rights Agreement. Without limiting the
generality of the foregoing, the Company represents that it has taken all
necessary actions to (a) render the Company Rights Agreement, dated as of
November 26, 1996, as amended (the "COMPANY RIGHTS AGREEMENT"), inapplicable to
the Merger and the other transactions contemplated by this Agreement, including
the Voting Agreement, (b) ensure that (i) neither Parent nor MergerCo, nor any
of their affiliates shall be deemed to have become an Acquiring Person (as such
term is defined in the Company's Rights Agreement) pursuant to the Company
Rights Agreement by virtue of the execution of this Agreement, the Voting
Agreement, the consummation of the Merger or the consummation of the other
transactions contemplated hereby and (ii) a Distribution Date (as such term is
defined in the Company Rights Agreement) or similar event does not occur by
reason of the execution of this Agreement and the Voting Agreement, the
consummation of the Merger, or the

                                      A-21
<PAGE>
consummation of the other transactions contemplated hereby and (c) provide that
the Final Expiration Date (as defined in the Company Rights Agreement) shall be
immediately prior to the Effective Time.

    5.27  OWNERSHIP OF PARENT COMMON STOCK; AFFILIATES AND ASSOCIATES.  As of
the date hereof, neither the Company nor any of its affiliates or associates (as
such terms are defined under the Exchange Act) (a) beneficially owns, directly
or indirectly, or (b) is a party to any agreement, arrangement or understanding
for the purpose of acquiring, holding, voting or disposing of any shares of
capital stock of Parent.

    5.28  COMPLIANCE WITH THE HART-SCOTT-RODINO ACT.  No person or entity,
directly or indirectly through fiduciaries, agents, controlled entities or other
means, holds fifty percent (50%) or more of the outstanding voting securities
of, or has the contractual right to designate fifty percent (50%) or more of the
directors of, the Company. In addition, the Company (a) does not produce and
derive annual sales or revenues in excess of $10,000,000 from products within
industries 2000-3999 as coded in the Standard Industrial Classification Manual
(1972 edition) published by the Executive Office of the President of the United
States, Office of Management and Budget; and (b) has less than $10,000,000 in
total assets, as stated on the last regularly prepared balance sheet of the
Company at the time of Closing.

    5.29  NO CONTRACTS WITH AFFILIATES.  Except as disclosed in Section 5.29 of
the Company Disclosure Schedule, the Company has not entered into any agreement,
contract, subcontract, lease, understanding, instrument, note, option, warranty,
purchase order, license, sublicense, insurance policy or legally binding
commitment or undertaking of any nature with any of its officers, directors or
shareholders, except pursuant to the Stock Option Plans and employment
agreements, consulting agreements or Company Warrants in each case as set forth
in Section 5.29 of the Company Disclosure Schedule.

    5.30  NO CONTROL SHARE ACQUISITION.  Assuming that the only shares of
Company Common Stock which may be deemed to be owned (beneficially or of record)
by Parent are shares subject to the Voting Agreement, the execution, delivery
and performance of this Agreement, the Voting Agreement and the consummation of
the Transactions will not violate or conflict with, and are exempt from, any
provisions of Section 302A.671 of the MBCA.

                                   ARTICLE VI
                    REPRESENTATIONS AND WARRANTIES OF PARENT

    Except as set forth in the disclosure letter delivered at or prior to the
execution hereof to the Company, which shall refer to the relevant Sections of
this Agreement (the "PARENT DISCLOSURE SCHEDULE"), each of Parent and MergerCo
represents and warrants to the Company as follows:

    6.1  EXISTENCE; GOOD STANDING; AUTHORITY.  Each of Parent and MergerCo is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Delaware. Each of Parent and MergerCo is duly licensed or
qualified to do business as a foreign corporation and is in good standing under
the laws of any other state of the United States in which the character of the
properties owned or leased by it therein or in which the transaction of its
business makes such qualification necessary, except where the failure to be so
licensed or qualified would not reasonably be expected to have a material
adverse effect on the current business, results of operations or financial
condition of Parent and the subsidiaries of the Parent (the "PARENT
SUBSIDIARIES") taken as a whole (a "PARENT MATERIAL ADVERSE EFFECT"). Each of
Parent and MergerCo has all requisite corporate power and authority to own,
operate, lease and encumber its properties and carry on its business as now
conducted.

                                      A-22
<PAGE>
    6.2  AUTHORIZATION, VALIDITY AND EFFECT OF AGREEMENTS.  Each of Parent and
MergerCo has the requisite power and authority to enter into the Transactions
and to execute and deliver this Agreement. The Board of Directors of Parent (the
"PARENT BOARD") has approved this Agreement, the Merger and the other
Transactions. The Board of Directors of MergerCo and the stockholder of MergerCo
have approved this Agreement and the Transactions. In connection with the
foregoing, the Parent Board has taken such actions and votes as are necessary on
its part to render the provisions of Section 203 of the DGCL and all other
applicable takeover statutes inapplicable to this Agreement, the Merger and the
other Transactions. The execution by Parent and MergerCo of this Agreement and
the consummation of the Transactions have been duly authorized by all requisite
corporate action on the part of Parent and MergerCo. This Agreement, assuming
due and valid authorization, execution and delivery thereof by the Company,
constitutes a valid and legally binding obligation of Parent and MergerCo,
enforceable against Parent and MergerCo in accordance with its terms, subject to
applicable bankruptcy, insolvency, moratorium or other similar laws relating to
creditors' rights and general principles of equity.

    6.3  CAPITALIZATION.

        (a) The capital stock of Parent consists of Parent Common Stock. There
    are 40,000,000 shares of Parent Common Stock authorized, and as of the date
    of this Agreement, (i) 25,087,976 shares of Parent Common Stock were issued
    and outstanding and (ii) 2,337,727 shares of Parent Common Stock have been
    authorized and reserved for issuance, of which 750,000 have been reserved
    for issuance for grant pursuant to Parent's Amended and Restated 2000 Stock
    Option and Grant Plan (the "PARENT STOCK OPTION PLAN") subject to adjustment
    on the terms set forth in the Parent Stock Option Plan, 850,000 have been
    reserved for issuance pursuant to the Parent's Employee Stock Purchase Plan
    and 737,727 shares of Parent Common Stock were authorized and reserved for
    issuance upon the exercise of the Parent Warrants (as defined herein). There
    are no outstanding options to purchase shares of Parent Common Stock under
    the Parent Stock Option Plan and options to purchase 750,000 shares of
    Parent Common Stock available for grant. As of the date of this Agreement,
    there are outstanding warrants to purchase 737,727 shares of Parent Common
    Stock (the "PARENT WARRANTS"). As of the date of this Agreement, 743,678
    shares of Parent Common Stock and no shares of Parent Preferred Stock were
    held in the treasury of Parent.

        (b) As of the date of this Agreement, Parent had no shares of Parent
    Common Stock reserved for issuance other than as described above. The
    authorized capital stock of MergerCo consists of 1,000 shares of MergerCo
    Common Stock, of which 100 shares were outstanding as of the date of this
    Agreement and held by Parent. MergerCo is a direct wholly owned subsidiary
    of Parent, was formed solely for the purpose of engaging in the transactions
    contemplated hereby, has engaged in no other business activities and has
    conducted its operations only as contemplated hereby. All such issued and
    outstanding shares of capital stock of Parent are duly authorized, validly
    issued, fully paid, nonassessable and free of preemptive rights. Parent has
    no outstanding bonds, debentures, notes or other obligations the holders of
    which have the right to vote (or which are convertible into or exercisable
    for securities having the right to vote) with the stockholders of Parent on
    any matter. Except for the Parent Options (all of which have been issued
    under the Parent Stock Option Plan) and Parent Warrants, there are not at
    the date of this Agreement any existing options, warrants, calls,
    subscriptions, convertible securities, or other rights, agreements or
    commitments that obligate Parent to issue, transfer or sell any shares of
    capital stock of Parent.

        (c) There are no agreements or understandings to which Parent or any
    Material Parent Subsidiary is a party with respect to the voting of any
    shares of capital stock of Parent or that restrict the transfer of any such
    shares, nor does Parent have knowledge of any third party agreements or
    understandings with respect to the voting of any such shares or that
    restrict the transfer of any such shares. There are no outstanding
    contractual obligations of Parent or any Material Parent Subsidiary to
    repurchase, redeem or otherwise acquire any shares of capital stock,

                                      A-23
<PAGE>
    partnership interests or any other securities of Parent or any Material
    Parent Subsidiary. Except as set forth in Section 6.3(c) of the Parent
    Disclosure Schedule, neither Parent nor any Material Parent Subsidiary is
    under any obligation, contingent or otherwise, by reason of any agreement to
    register the offer and sale or resale of any of their securities under the
    Securities Act.

    6.4  NO VIOLATION; CONSENTS.  Except as set forth in Section 6.4 of the
Parent Disclosure Schedule, neither the execution and delivery by Parent of this
Agreement nor consummation by Parent of the Transactions in accordance with the
terms hereof, will conflict with or result in a breach of any provisions of the
Parent Certificate or the Parent Bylaws. Except as set forth in Section 6.4 of
the Parent Disclosure Schedule, the execution and delivery by Parent of this
Agreement and consummation by Parent of the Transactions in accordance with the
terms hereof will not violate, or conflict with, or result in a breach of any
provision of, or constitute a default (or an event which, with notice or lapse
of time or both, would constitute a default) under, or result in the termination
or in a right of termination or cancellation of, or accelerate the performance
required by, or result in the creation of any lien, security interest, charge or
encumbrance upon any of the properties of Parent or the Material Parent
Subsidiaries under, or result in being declared void, voidable or without
further binding effect, any of the terms, conditions or provisions of (a) any
note, bond, mortgage, indenture or deed of trust or (b) any license, franchise,
permit, lease, contract, agreement or other instrument, commitment or obligation
to which Parent or any of the Parent Subsidiaries is a party, or by which Parent
or any of the Material Parent Subsidiaries or any of their properties is bound,
except as otherwise would not have a Parent Material Adverse Effect. Other than
the Regulatory Filings, and based upon the accuracy of the Company's
representation and warranty contained in Section 5.28 hereof, the execution and
delivery of this Agreement by Parent does not, and the performance of this
Agreement by Parent and consummation of the Transactions does not, require any
consent, approval or authorization of, or declaration, filing or registration
with, any governmental or regulatory authority, except where the failure to
obtain any such consent, approval or authorization of, or declaration, filing or
registration with, any governmental or regulatory authority would not have a
Parent Material Adverse Effect.

    6.5  SEC DOCUMENTS.  Parent has filed all required forms, reports and
documents with the SEC since August 6, 1996 (collectively, the "PARENT SEC
REPORTS"), all of which were prepared in accordance with the applicable
requirements of the Securities Laws. As of their respective dates, the Parent
SEC Reports (a) complied as to form in all material respects with the applicable
requirements of the Securities Laws and (b) did not contain any untrue statement
of a material fact or omit to state a material fact required to be stated
therein or necessary to make the statements made therein, in the light of the
circumstances under which they were made, not misleading. Each of the
consolidated balance sheets of Parent included in or incorporated by reference
into the Parent SEC Reports (including the related notes and schedules) fairly
presents the consolidated financial position of Parent and the Parent
Subsidiaries as of its date and each of the consolidated statements of income,
retained earnings and cash flows of Parent included in or incorporated by
reference into the Parent SEC Reports (including any related notes and
schedules) fairly presents the results of operations, retained earnings or cash
flows, as the case may be, of Parent and the Parent Subsidiaries for the periods
set forth therein (subject, in the case of unaudited statements, to normal
year-end audit adjustments that would not be material in amount or effect), in
each case in accordance with generally accepted accounting principles
consistently applied during the periods involved, except as may be noted therein
and except, in the case of the unaudited statements, as permitted by Form 10-Q
pursuant to Section 13 or 15(d) of the Exchange Act.

    6.6  NO BROKERS.  Neither Parent nor any of the Parent Subsidiaries has
entered into any contract, arrangement or understanding with any person or firm
that may result in the obligation of such entity or the Company to pay any
finder's fees, brokerage or agent's commissions or other like payments in
connection with the negotiations leading to this Agreement or consummation of
the Transactions, except that Parent may pay certain fees and expenses to
Covington & Associates ("Covington") in

                                      A-24
<PAGE>
connection with advisory services provided in connection with Parent's
evaluation of the transactions contemplated hereby. Other than the Company's
arrangements with Piper Jaffray and the Parent's arrangements, if any, with
Covington, Parent is not aware of any claim for payment of any finder's fees,
brokerage or agent's commissions or other like payments in connection with the
negotiations leading to this Agreement or consummation of the Transactions.

    6.7  REORGANIZATION.  As of the date of this Agreement, Parent has no reason
to believe that the Merger will not qualify as a "reorganization" within the
meaning of Section 368(a) of the Code.

    6.8  OWNERSHIP OF COMPANY COMMON STOCK; AFFILIATES AND ASSOCIATES.  As of
the date hereof, neither Parent nor any of its affiliates or associates (as such
terms are defined under the Exchange Act) (a) beneficially owns, directly or
indirectly, or (b) is a party to any agreement, arrangement or understanding for
the purpose of acquiring, holding, voting or disposing of any shares of capital
stock of the Company.

    6.9  CERTAIN ACTIONS.  Neither Parent nor MergerCo controls, is controlled
by or is under common control of any entity set forth in Section 6.9 of the
Parent Disclosure Schedule.

    6.10  LITIGATION.  Except as set forth in Section 6.10 of the Parent
Disclosure Schedule, there is no litigation, suit, action or proceeding pending
or, to the knowledge of the Parent, threatened against the Parent, as to which
there is a reasonable likelihood of an adverse determination and which, if
adversely determined, individually or in the aggregate with all such other
litigation, suits, actions or proceedings, would (a) have a Parent Material
Adverse Effect, (b) materially and adversely affect the Parent's ability to
perform its obligations under this Agreement or (c) prevent the consummation of
any of the Transactions.

    6.11  COMPLIANCE WITH APPLICABLE LAW.  Except as set forth in Section 6.11
of the Parent Disclosure Schedule, or where the failure would not have a Parent
Material Adverse Effect (a) the Parent holds, and is in compliance with the
terms of, all permits, licenses, exemptions, orders and approvals of all
Governmental Entities necessary for the current and presently proposed conduct
of its business ("PARENT PERMITS"), (b) no fact exists or event has occurred,
and no action or proceeding is pending or, to the Parent's knowledge,
threatened, that has a reasonable possibility of resulting in a revocation,
nonrenewal, termination, suspension or other impairment of any Parent Permits,
(c) the business of the Parent is not being conducted in violation of any
applicable law, ordinance, regulation, judgment, decree or order of any
Governmental Entity, and (d) to the knowledge of the Parent, (i) no
investigation or review by any Governmental Entity with respect to the Parent is
pending or threatened or has been undertaken within the past five (5) years, and
(ii) no Governmental Entity has indicated an intention to conduct the same. For
purposes of this Agreement, "GOVERNMENTAL ENTITY" means any state or federal
government or governmental authority or any United States or state court of
competent jurisdiction.

                                  ARTICLE VII
                                   COVENANTS

    7.1  NO SOLICITATIONS.

        (a) The Company represents and warrants that it has terminated any
    discussions or negotiations relating to, or that may reasonably be expected
    to lead to, any Acquisition Proposal (as defined herein) and will promptly
    request the return of all confidential information regarding the Company
    provided to any third party prior to the date of this Agreement pursuant to
    the terms of any confidentiality agreements entered into in connection with
    any such Acquisition Proposal. Except as permitted by this Agreement, the
    Company shall not, and shall not authorize or permit any of its officers,
    directors or employees or any investment banker, financial advisor,
    attorney, accountant or other representative retained by it to, directly or
    indirectly, (i) solicit,

                                      A-25
<PAGE>
    initiate or encourage (including by way of furnishing non-public
    information), or take any other action to facilitate, any inquiries or the
    making of any proposal that constitutes an Acquisition Proposal, or
    (ii) engage or participate in any discussions or negotiations with, or
    provide any confidential information or data to, any person relating to an
    Acquisition Proposal, or otherwise facilitate any effort or attempt to make
    or implement an Acquisition Proposal; and the Company will immediately cease
    and cause to be terminated any existing activities, negotiations or
    discussions with any persons conducted heretofore with respect to any of the
    foregoing and will take the necessary steps to inform the individuals or
    entities referred to above of the obligations undertaken in this Section.

        (b) The Company Board may not withdraw or modify, or propose to withdraw
    or modify, in a manner adverse to Parent or MergerCo, its approval or
    recommendation of this Agreement or the Merger; PROVIDED, HOWEVER, that
    notwithstanding anything contained in this Section 7.1 or any other
    provision of this Agreement, prior to the Company shareholders meeting, the
    Company Board may so withdraw or modify, or propose to withdraw or modify,
    its approval or recommendation of this Agreement or the Merger and the
    Company may participate in discussions or negotiations with or furnish
    information to a third party making an unsolicited Acquisition Proposal (a
    "POTENTIAL ACQUIROR") or approve or recommend an unsolicited Acquisition
    Proposal, if (i) a majority of the disinterested directors of the Company
    Board determines in good faith, after consultation with its independent
    financial advisor, that a Potential Acquiror has submitted to the Company a
    written Acquisition Proposal which sets forth a price to be paid by the
    Potential Acquiror and which, if consummated, would be more favorable to the
    Company's shareholders, from a financial point of view, than the Merger (a
    "SUPERIOR PROPOSAL"), (ii) the Company Board has determined in good faith,
    based on consultation with its outside legal counsel experienced in such
    matters (which may include Dorsey & Whitney LLP, the Company's current
    counsel) that such written Acquisition Proposal appears to be a Superior
    Proposal based upon the terms and conditions set forth therein, (iii) the
    Company Board has determined in good faith, based on consultation with its
    independent financial advisor, that such Potential Acquiror is financially
    capable of consummating such Superior Proposal and that such Superior
    Proposal is likely to be consummated, and (iv) a majority of the
    disinterested directors of the Company Board determines in good faith, after
    receiving advice from such outside legal counsel that participating in
    discussions or negotiations or furnishing information or approving or
    recommending the unsolicited Acquisition Proposal is required by the Company
    Board's fiduciary duties under applicable law.

        (c) The Company shall promptly notify (but in any event within one
    (1) business day Parent of the Company's first receipt of a written
    Acquisition Proposal and of the material terms and conditions thereof and
    any material changes thereto. Notwithstanding anything to the contrary in
    this Agreement, the Company shall not be required to disclose to Parent the
    identity of the Potential Acquiror making any such Acquisition Proposal.

        (d) Nothing contained in this Section 7.1 shall prohibit the Company
    from at any time taking and disclosing to its shareholders a position
    contemplated by Rule 14d-9 or Rule 14e-2 promulgated under the Exchange Act
    or making any disclosure required by Rule 14a-9 promulgated under the
    Exchange Act.

        (e) As used in this Agreement, the term "ACQUISITION PROPOSAL" shall
    mean any proposed or actual (i) merger, consolidation or similar transaction
    involving the Company, (ii) sale, lease or other disposition, directly or
    indirectly, by merger, consolidation, share exchange or otherwise, of any
    assets of the Company representing 15% or more of the assets of the Company,
    (iii) issue, sale or other disposition by the Company of (including by way
    of merger, consolidation, share exchange or any similar transaction)
    securities (or options, rights or warrants to purchase, or securities
    convertible into, such securities) representing 15% or more of the votes
    associated with the outstanding securities of the Company, (iv) tender offer
    or exchange offer in which any person

                                      A-26
<PAGE>
    shall acquire beneficial ownership (as such term is defined in Rule 13d-3
    under the Exchange Act), or the right to acquire beneficial ownership, or
    any "group" (as such term is defined under the Exchange Act) shall have been
    formed which beneficially owns or has the right to acquire beneficial
    ownership of, 15% or more of the outstanding shares of Company Common Stock,
    (v) recapitalization, restructuring, liquidation, dissolution, or other
    similar type of transaction with respect to the Company or (vi) transaction
    that is similar in form, substance or purpose to any of the foregoing
    transactions; PROVIDED, HOWEVER, that the term "Acquisition Proposal" shall
    not include the Merger and the other Transactions.

    7.2  CONDUCT OF BUSINESSES.

        (a) GENERAL. Prior to the Effective Time, except as specifically
    permitted by this Agreement, unless the other party has consented in writing
    thereto, Parent and the Company shall:

           (i) use their reasonable best efforts, and shall cause each of their
       respective Subsidiaries to use their reasonable best efforts, to preserve
       intact their business organizations and goodwill and keep available the
       services of their respective officers and material employees;

           (ii) subject to Section 7.1 and this Section 7.2, confer on a regular

       prospects or the normal course of their businesses, any material
       governmental complaints, investigations or hearings (or communications
       indicating that the same may be contemplated), or the breach in any
       material respect of any representation or warranty contained herein; and

           (iv) promptly deliver to the other true and correct copies of any
       report, statement or schedule filed by or with respect to it with the SEC
       subsequent to the date of this Agreement.

        (b) CONDUCT BY THE COMPANY. Prior to the Effective Time, except as
    specifically permitted by this Agreement, unless Parent or MergerCo has
    consented in writing thereto, the Company shall use its reasonable best
    efforts to conduct its operations according to its usual, regular and
    ordinary course in substantially the same manner as heretofore conducted.
    Without limiting the generality of the foregoing, the Company shall not
    (except as expressly permitted by this Agreement or to the extent Parent or
    MergerCo shall otherwise consent in writing which shall not be unreasonably
    withheld or delayed):

           (i) (A) declare, set aside or pay any dividend or other distribution

       respect of any of its capital stock, (B) split, combine or reclassify any
       of its capital stock or (C) repurchase, redeem or otherwise acquire any

       holders upon exercise of Company Options or (y) the redemption of

       to issue, sell or deliver (whether through the issuance or granting of
       options, warrants, commitments, subscriptions, rights to purchase or

        (a) The Company and Parent shall prepare and Parent shall file with the
    SEC, under the Exchange Act and the Securities Act, a registration statement
    on Form S-4 (such registration statement, together with any amendments or
    supplements thereto, the "FORM S-4") which shall include a proxy

    together with any amendments or supplements thereto, the "PROXY STATEMENT")
    relating to the shareholders meeting of the Company and the vote of the

    supplemented, to be filed with the SEC and to be disseminated to the
    Company's shareholders as and to the extent required by applicable federal
    and state securities laws. Each of Parent and the Company agrees that the
    information provided by it for inclusion in the Proxy Statement or the
    Form S-4 and each amendment or supplement thereto, at the time of mailing
    thereof and at the time of the meeting of shareholders of the Company, will
    not include an untrue statement of a material fact or omit to state a
    material fact required to be stated therein or necessary to make the
    statements therein, in light of the circumstances under which they were
    made, not misleading. Parent will advise the Company, and deliver copies (if
    any) to the Company, promptly after either receives notice thereof, of any
    request by the SEC for amendment of the Proxy Statement or the Form S-4 or
    comments thereon and responses thereto or requests by the SEC for additional
    information, or notice of the time when the Form S-4 has become effective or
    any supplement or amendment has been filed, the issuance of any stop order
    or the suspension of the qualification of the securities issuable in
    connection with the Merger for offering or sale in any jurisdiction.

        (b) The Company shall use its reasonable best efforts to promptly mail
    the Proxy Statement to its shareholders.

    to, obtaining any consent to inclusion of the Company's financial statements
    and the reports of the Company's independent public accountants with respect
    thereto in any filing made pursuant to any federal or state securities laws
    (and any public disclosure related thereto), as well as using its best
    effort to cause its independent public accountants to prepare and deliver a
    comfort letter or letters reasonably acceptable to any placement agent or
    underwriter retained by Parent in connection with the placement or offering
    of the securities registered pursuant to any such registration statement.

    7.9  LISTING APPLICATION.  Parent shall promptly prepare and submit to the

information about itself and its business and operation and all necessary
financial information to the other as the other may reasonably request in
connection with such AMEX listing process. Each of Parent and the Company agrees
promptly to correct any information provided by it for use in the AMEX listing

misleading in any material respect. Each of Parent and the Company will advise
and deliver copies (if any) to the other parties, promptly after it receives
notice thereof, of any request by the AMEX for amendment of any submitted
materials or comments thereon and responses thereto or requests by the AMEX for

        (a) Promptly following the date of this Agreement, the Company shall
    deliver to Parent a list of names and addresses of those persons who and as
    requested by Parent thereafter were, in the Company's reasonable judgment,
    at the record date for its shareholders' meeting to approve the Merger,
    "affiliates" (each such person, a "COMPANY AFFILIATE") of the Company within
    the meaning of Rule 145. Parent shall be entitled to place legends as
    specified on Exhibit B on the certificates evidencing any shares of Parent
    Common Stock to be received by such Affiliates pursuant to the

                                      A-30
<PAGE>

    with the terms of such legends.

        (b) Intentionally Omitted.

        (c) Parent shall file the reports required to be filed by it under the
    Exchange Act and the rules and regulations adopted by the SEC thereunder,
    and it will take such further action as any Affiliate of the Company may
    reasonably request, all to the extent, if any, required from time to time to
    enable such Affiliate to sell shares of Parent Common Stock received by such
    Affiliate in the Merger without registration under the Securities Act
    pursuant to (i) Rule 145(d)(1) or (ii) any successor rule or regulation
    hereafter adopted by the SEC.

    7.12  OFFICERS' AND DIRECTORS' INDEMNIFICATION.

        (a) In the event of any threatened or actual claim, action, suit,
    proceeding or investigation, whether civil, criminal or administrative,
    including, without limitation, any such claim, action, suit, proceeding or
    investigation in which any person who is now, or has been at any time prior
    to the date hereof, or who becomes prior to the Effective Time, a director,
    officer, employee, fiduciary or agent of the Company (the "INDEMNIFIED
    PARTIES") is, or is threatened to be, made a party based in whole or in part
    on, or arising in whole or in part out of, or pertaining to (i) the fact
    that he is or was a director, officer, employee, fiduciary or agent of the
    Company, or is or was serving at the request of the Company as a director,
    officer, employee, fiduciary or agent of another corporation, partnership,
    joint venture, trust or other enterprise (ii) any matter pursuant to which
    such Indemnified Party is entitled to indemnification under applicable law
    or the Company Charter, or (iii) the negotiation, execution or performance
    of this Agreement or any of the Transactions, whether in any case asserted
    or arising before or after the Effective Time, the parties hereto agree to
    cooperate and use their reasonable best efforts to defend against and
    respond thereto. It is understood and agreed that (A) the Company shall
    indemnify and hold harmless, and after the Effective Time the Surviving
    Corporation shall indemnify and hold harmless, as and to the full extent
    permitted by applicable law, each Indemnified Party against any losses,
    claims, damages, liabilities, costs, expenses (including attorneys' fees and
    expenses), judgments, fines and amounts paid in settlement in connection
    with any such threatened or actual claim, action, suit, proceeding or
    investigation, and in the event of any such threatened or actual claim,
    action, suit, proceeding or investigation (whether asserted or arising
    before or after the Effective Time), the Company, and the Surviving
    Corporation after the Effective Time, shall promptly pay expenses in advance
    of the final disposition of any claim, suit, proceeding or investigation to
    each Indemnified Party to the full extent permitted by law, (B) the
    Indemnified Parties may retain counsel satisfactory to them, and the Company
    and the Surviving Corporation, shall pay all fees and expenses of such
    counsel for the Indemnified Parties within 30 days after statements therefor
    are received, and (C) the Company and the Surviving Corporation will use
    their respective reasonable best efforts to assist in the vigorous defense
    of any such matter; provided that neither the Company nor the Surviving
    Corporation shall be liable for any settlement effected without its prior
    written consent (which consent shall not be unreasonably withheld); and
    provided further that the Surviving Corporation shall have no obligation
    hereunder to any Indemnified Party when and if a court of competent
    jurisdiction shall ultimately determine, and such determination shall have
    become final and non-appealable, that indemnification of such Indemnified
    Party in the manner contemplated hereby is prohibited by applicable law. Any
    Indemnified Party wishing to claim indemnification under this Section 7.12,
    upon learning of any such claim, action, suit, proceeding or investigation,
    shall notify the Company and, after the Effective Time, the Surviving
    Corporation, thereof;

                                      A-31
<PAGE>
    provided that the failure to so notify shall not affect the obligations of
    the Company and the Surviving Corporation except to the extent such failure
    to notify materially prejudices such party.

        (b) Parent agrees that all rights to indemnification existing in favor
    of, and all limitations on the personal liability of, the directors,
    officers, employees and agents of the Company provided for in the Articles
    of Organization or Bylaws as in effect as of the date hereof with respect to
    matters occurring prior to the Effective Time, and including the Merger,
    shall continue in full force and effect for a period of not less then six
    years from the Effective Time; PROVIDED, HOWEVER, that all rights to
    indemnification in respect of any claims (each a "CLAIM") asserted or made
    within such period shall continue until the disposition of such Claim. Prior
    to the Effective Time, the Company shall purchase an extended reporting
    period endorsement under the Company's existing directors' and officers'
    liability insurance coverage for the Company's directors and officers in a
    form acceptable to the Company which shall provide such directors and
    officers with coverage for six years following the Effective Time of not
    less than the existing coverage under, and have other terms not materially
    less favorable to, the insured persons than the directors' and officers'
    liability insurance coverage presently maintained by the Company.

        (c) This Section 7.12 is intended for the irrevocable benefit of, and to
    grant third party rights to, the Indemnified Parties and shall be binding on
    all successors and assigns of Parent, the Company and the Surviving
    Corporation. Each of the Indemnified Parties shall be entitled to enforce
    the covenants contained in this Section 7.12.

        (d) In the event that the Surviving Corporation or any of its successors
    or assigns (i) consolidates with or merges into any other person or entity
    and shall not be the continuing or surviving corporation or entity of such
    consolidation or merger or (ii) transfers or conveys all or substantially
    all of its properties and assets to any person or entity, then, and in each
    such case, proper provision shall be made so that the successors and assigns
    of the Surviving Corporation assume the obligations set forth in this
    Section 7.12.

    7.13  ACCESS TO INFORMATION; CONFIDENTIALITY.  From the date hereof until
the Effective Time, each of Parent and the Company shall, and shall cause each
of their respective Subsidiaries and each of their and their respective
Subsidiaries' officers, employees and agents to, afford to the other and to the
officers, employees and agents of the other complete access, except to the
extent such access is prohibited by the terms of a binding agreement between the
Company and a third party, at all reasonable times to such officers, employees,
agents, properties, books, records and contracts, and shall furnish to the other
such financial, operating and other data and information as the other may
reasonably request. Prior to the Effective Time, Parent shall hold in confidence
all such information on the terms and subject to the conditions contained in
that certain confidentiality agreement between Parent and the Company dated as
of August 9, 2000 (the "CONFIDENTIALITY AGREEMENT"). The Company hereby waives
the provisions of the Confidentiality Agreement as and to the extent necessary
to permit the making and consummation of the transactions contemplated by this
Agreement. At the Effective Time, the Confidentiality Agreement shall terminate.

    7.14  PUBLICITY.  Parent and the Company shall consult with each other
before issuing any press release or otherwise making any public statements with
respect to this Agreement or any transaction contemplated hereby and shall not
issue any such press release or make any such public statement without the prior
consent of the other party, which consent shall not be unreasonably withheld;
PROVIDED, HOWEVER, that a party may, without the prior consent of the other
party, issue such press release or make such public statement as may be required
by law or the applicable rules of any stock exchange if it has used its best
efforts to consult with the other party and to obtain such party's consent but
has been unable to do so in a timely manner. In this regard, the parties shall
make a joint public announcement of the Transactions no later than (i) the close
of trading on the AMEX on the day this Agreement is signed, if such signing
occurs during a business day and prior to the close of such trading

                                      A-32
<PAGE>
or (ii) the opening of trading on the AMEX on the business day following the
date on which this Agreement is signed, if such signing does not occur during a
business day or occurs on a business day but after the close of such trading.

    7.15  EMPLOYEE BENEFITS.

        (a) Parent agrees that the Company will honor, and from and after the
    Effective Time, Parent will cause the Surviving Corporation to honor, all
    obligations under (i) the existing terms of the employment and severance
    agreements set forth in Section 7.15 of the Company Disclosure Schedule to
    which the Company is presently a party, except as may otherwise be agreed to
    by the parties thereto, and (ii) the Company's general severance policy as
    set forth in Section 7.15 of the Company Disclosure Schedule.

        (b) If any employee of the Company becomes a participant in any employee
    benefit plan, practice or policy of the Surviving Corporation, such employee
    shall, to the extent permitted by such plan, practice or policy, be given
    credit under such plan, practice or policy for all service prior to the
    Effective Time with the Company and prior to the time such employee becomes
    such a participant, for purposes of eligibility (including, without
    limitation, waiting periods) and vesting but not for any other purposes for
    which such service is either taken into account or recognized (including,
    without limitation, benefit accrual); PROVIDED, HOWEVER, that such employees
    will be given credit for such service for purposes of any vacation policy.

    7.16  ADVICE OF CHANGES.  Parent and the Company shall each promptly advise
the other party of any change or event (a) having a Material Adverse Effect on
it or (b) which it believes would or would be reasonably likely to cause or
constitute a material breach of any of its representations, warranties or
covenants contained herein.

    7.17  DELISTING.  Each of the parties hereto agrees to cooperate with each
other in taking, or causing to be taken, all actions necessary to delist the
Company Common Stock from the NASDAQ, provided that such delisting shall not be
effective until after the Effective Time.

    of such representations and warranties to be so true and correct (without
    giving effect to any limitation as to materiality or material adverse effect
    set forth therein), individually or in the aggregate, does not have, and
    would not reasonably be expected to have a Parent Material Adverse Effect.

        (b) PERFORMANCE OF OBLIGATIONS OF PARENT. Parent shall have performed in
    all material respects all obligations required to be performed by it under

    obtained by Parent and the Parent Subsidiaries and affiliated entities in
    connection with the execution, delivery and performance of this Agreement
    shall have been obtained or made, except where the failure to have obtained
    or made any such consent, authorization, order, approval, filing or
    registration, could not reasonably be expected to have a Parent Material
    Adverse Effect.

        (f) TAX OPINION. The Company shall have received a written opinion from
    its counsel, Dorsey & Whitney LLP, in form and substance reasonably
    satisfactory to it, to the effect that the Merger will constitute a tax free

    made at and as of such time (except to the extent expressly made as of an
    earlier date, in which case as of such date), except, with respect to the
    Effective Date, where the failure of such representations and warranties to
    be so true and correct (without giving effect to any limitation as to
    materiality or material adverse effect set forth therein), individually or
    in the aggregate, does not have, and would not reasonably be expected to
    have a Company Material Adverse Effect.

        (b) PERFORMANCE OF OBLIGATIONS OF THE COMPANY. The Company shall have
    performed in all material respects all obligations required to be performed
    by it under this Agreement.

    expected to have a Company Material Adverse Effect (other than any
    (i) changes generally affecting the industries in which the Company
    operates, including changes due to actual or proposed changes in law or
    regulations, (ii) changes that are related to a general drop in stock prices
    in the United States resulting from political or economic turmoil, or

    pendency of the Merger, including disruptions to the Company's business or
    any action or inaction taken by any party listed on Section 8.3(c) of the

    any agreement between the Company and such party.

        (d) OFFICERS' CERTIFICATE. Parent shall have received a certificate of
    the Chief Executive Officer or President and the Controller of the Company
    to the effect that the statements set forth in paragraphs (a), (b) and

    execution, delivery and performance of this Agreement shall have been
    obtained or made, except where the failure to have obtained or made any such

    reasonably be expected to have a Company Material Adverse Effect.

        (f) REDEMPTION OF COMPANY SERIES B PREFERRED STOCK. Company shall have

        (g) TAX OPINION. Parent shall have received a written opinion from its
    counsel, Goodwin, Procter & Hoar LLP, in form and substance reasonably
    satisfactory to it, to the effect that the Merger will constitute a tax-free

                       TERMINATION, AMENDMENT AND WAIVER

    9.1  TERMINATION.  This Agreement may be terminated and abandoned at any
time prior to the Effective Time, whether before or after the approval of
matters presented in connection with the Merger by the stockholders of Parent
and the Company:

    (a) by the mutual written consent of Parent, MergerCo and the Company.

    (b) by either of Parent or MergerCo, or the Company:

        (i) if any required approval of the shareholders of the Company that is
    a condition to the obligations of Parent, MergerCo or the Company under
    Section 8.1 of this Agreement shall not have been obtained by reason of the
    failure to obtain the required vote upon a vote held at a duly held meeting
    of shareholders or at any adjournment thereof; or

        (ii) if any Governmental Entity shall have issued an Injunction or taken
    any other action (which Injunction or other action the parties hereto shall
    use their best efforts to lift), which permanently restrains, enjoins or
    otherwise prohibits the Merger; or

       (iii) if, without any material breach by the terminating party of its
    obligations under this Agreement, the Merger shall not have occurred on or
    before March 31, 2001; PROVIDED, HOWEVER, that neither Parent, MergerCo nor
    the Company shall terminate this Agreement prior to March 31, 2001 if the
    Merger has not occurred by reason of the nonsatisfaction of the condition
    set forth in Section 8.1(b) hereof or the pendency of a non-final
    Injunction, and Parent, MergerCo and the Company shall use their best
    efforts to cause such condition to be satisfied (including, without
    limitation, by complying with the requirements of the FTC or other
    comparable Governmental Entity to divest of assets or otherwise in
    connection with the consummation of the Transactions or in settlement of any
    action brought by it) or have any such Injunction stayed or reversed.

        (c) by the Company if Parent or MergerCo shall have breached in any
    material respect any of its representations, warranties, covenants or other
    agreements contained in this Agreement, which breach cannot be or has not
    been cured within fifteen (15) business days after the giving of written
    notice to Parent and MergerCo except, in any case, for such breaches which
    are not reasonably likely to have a Parent Material Adverse Effect.

        (d) by Parent or MergerCo if the Company shall have breached in any
    material respect any of its representations, warranties, covenants or other
    agreements contained in this Agreement, which breach cannot be or has not
    been cured within fifteen (15) business days after the giving of written
    notice to the Company except, in any case, for such breaches which are not
    reasonably likely to have a Company Material Adverse Effect.

        (e) by Parent or MergerCo, if (i) the Company Board shall have failed to
    make, or shall have withdrawn, amended, modified or changed its approval or
    recommendation of this Agreement or any of the transactions contemplated
    hereby; (ii) the Company shall have failed to include the favorable
    recommendation of its Board of Directors of this Agreement and the
    transactions contemplated hereby in the Proxy Statement; (iii) the Company
    Board shall have recommended that shareholders of the Company accept or
    approve a Superior Proposal by a person other than Parent; (iv) the Company
    Board shall publicly express no opinion and remain neutral in respect of any
    Acquisition Proposal or the Merger or the Transactions; (v) the Company
    Board shall propose or announce any intention to enter into any agreement
    with respect to an Acquisition Proposal, or (vi) the Company or its Board of
    Directors shall have resolved to do any of the foregoing.

        (f) by the Company, prior to the Company's shareholders meeting,
    concurrently with entering into a definitive agreement to effect a Superior
    Proposal in accordance with Section 7.1; PROVIDED,

                                      A-36
<PAGE>
    HOWEVER, that prior to terminating this Agreement pursuant to this
    Section 9.1(f) the Company shall have provided Parent and MergerCo with five
    (5) business days prior written notice of the Company's decision to so
    terminate. Such notice shall indicate in reasonable detail the terms and
    conditions of such Superior Proposal, including, without limitation, the
    amount and form of the proposed consideration and whether such Superior
    Proposal is subject to any material conditions. During such five (5) day
    period, the Company shall, and shall cause its respective financial and
    legal advisors to, consider any adjustment in the terms and conditions of
    this Agreement that Parent and may propose; provided further that the
    Company may not effect such termination pursuant to this Section 9.1(f)
    unless the Company immediately prior to such termination pays to Parent or
    its designee the Termination Fee due pursuant to Section 9.2 hereof.
    Notwithstanding the foregoing, the Company is not required to disclose to
    Parent the identity of the party making such Superior Proposal.

    9.2  EFFECT OF TERMINATION.

        (a) In the event of the termination of this Agreement pursuant to
    Section 9.1 hereof, this Agreement shall forthwith become null and void and
    have no effect, without any liability on the part of any party hereto or its
    affiliates, directors, officers or stockholders and all rights and
    obligations of any party hereto shall cease except for the agreements
    contained in Sections 7.9, 7.11 and 10.4 and this Section 9.2; PROVIDED,
    HOWEVER, that nothing contained in this Section 9.2 shall relieve any party
    from liability for any fraud or willful breach of this Agreement and Company
    shall be required to make payment to Parent as are required pursuant to this
    Article IX.

        (b) If (i) Parent or MergerCo terminates this Agreement pursuant to
    Section 9.1(e) or (ii) the Company terminates this Agreement pursuant to
    Section 9.1(f), then the Company shall pay immediately to Parent an amount
    in cash equal to $2,000,000 (the "TERMINATION FEE").

        (c) If any party terminates this Agreement pursuant to 9.1(b)(i) or
    (iii), or if Parent or MergerCo terminates this Agreement pursuant to
    9.1(d), and at any time prior to or within one year after such termination
    the Company enters into an agreement relating to an Acquisition Proposal
    with a person, other than any party listed on Section 9.2(c) of the general
    disclosure letter (the "GENERAL DISCLOSURE SCHEDULE"), specifically on the
    terms set forth in the agreements (if any) listed thereon, or the Company
    Board recommends or resolves to recommend to the Company's shareholders
    approval or acceptance of an Acquisition Proposal with a person other than
    any party listed on Section 9.2(c) of the General Disclosure Schedule, then,
    upon the entry into such agreement or the making of such recommendation or
    resolution, the Company shall pay to Parent the Termination Fee. Provided,
    however, that if Parent or MergerCo terminates this Agreement pursuant to
    9.1(d) and the breach by Company shall have been caused by a willful act,
    omission or other willful misconduct of the Company, then the Company shall
    pay to Parent an amount in cash equal to Parent's and MergerCo's
    out-of-pocket costs and expenses incurred in connection with this Agreement
    and the transactions contemplated hereby, including, without limitation,
    reasonable fees and disbursements of accountants, attorneys and investment
    bankers (the "EXPENSES") payable upon termination of this Agreement,
    PROVIDED, FURTHER, that at no time shall the aggregate amount payable by
    Company under this Section 9.2(c) exceed the amount of the Termination Fee.

        (d) The Company shall not enter into any agreement relating to an
    Acquisition Proposal with a person other than Parent or MergerCo at any time
    prior to or within one year after termination of this Agreement, unless such
    agreement provides that such person shall, upon the execution of such
    agreement, pay or have paid to Parent, to the extent due, any Termination
    Fee due under this Section 9.2.

        (e) The parties acknowledge and agree that the provisions for payment of
    the Termination Amount are included herein in order to induce Parent to
    enter into this Agreement and to

                                      A-37
<PAGE>
    reimburse Parent for incurring the costs and expenses related to entering
    into this Agreement and consummating the transactions contemplated hereby.
    Notwithstanding anything to the contrary set forth in this Agreement, in the
    event Parent is required to file suit to seek all or a portion of the
    Termination Amount, Parent shall be reimbursed by the Company for any and
    all expenses which it has incurred in enforcing its rights hereunder,
    including without limitation, attorneys' fees and expenses.

    9.3  AMENDMENT.  This Agreement may be amended by the parties hereto by an
instrument in writing signed on behalf of each of the parties hereto at any time
before or after any approval hereof by the stockholders of Parent and the
Company, but in any event following authorization by the Parent Board and the
Company Board; provided, however, that after any such stockholder approval, no
amendment shall be made which by law requires further approval by the
stockholders without obtaining such approval.

    9.4  EXTENSION; WAIVER.  At any time prior to the Closing, the parties
hereto may, to the extent legally allowed, (a) extend the time for the
performance of any of the obligations or other acts of the other party hereto,
(b) waive any inaccuracies in the representations and warranties contained
herein or in any document delivered pursuant hereto and (c) waive compliance
with any of the agreements or conditions contained herein. Any agreement on the
part of a party hereto to any such extension or waiver shall be valid only if
set forth in a written instrument signed on behalf of such party, but such
extension or waiver or failure to insist on strict compliance with an
obligation, covenant, agreement or condition shall not operate as a waiver of,
or estoppel with respect to, any subsequent or other failure.

    10.2  INTERPRETATION.  When a reference is made in this Agreement to
subsidiaries of Parent or the Company, the word "SUBSIDIARY" means any
corporation more than 50% of whose outstanding voting securities, or any
partnership, joint venture or other entity more than 50% of whose total equity
interest, is directly or indirectly owned by Parent or the Company, as the case
may be. Whenever the words "include," "includes" or "including" are used in this
Agreement, they shall be deemed to be followed by the words "without
limitation." The table of contents and headings contained in this Agreement are
for reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement.

    10.3  NON-SURVIVAL OF REPRESENTATIONS, WARRANTIES, COVENANTS AND
AGREEMENTS.  Except for Articles IV and X, the last sentence of Section 7.5, and
Sections 7.8, 7.9, 7.10 and 7.15, none of the representations, warranties,
covenants and agreements contained in this Agreement or in any instrument
delivered pursuant to this Agreement shall survive the Effective Time, and
thereafter there shall be no liability on the part of either Parent or the
Company or any of their respective officers, directors or stockholders in
respect thereof. Except as expressly set forth in this Agreement, there are no
representations or warranties of any party hereto, express or implied.

    10.4  MISCELLANEOUS.  This Agreement (a) constitutes, together with the
Confidentiality Agreement, the Parent Disclosure Schedule and the Company
Disclosure Schedule, the entire agreement and supersedes all of the prior
agreements and understandings, both written and oral, among the parties, or any
of them, with respect to the subject matter hereof, (b) shall be binding upon
and inure to the benefits of the parties hereto and their respective successors
and assigns and is not intended to confer upon any other person (except as set
forth below) any rights or remedies hereunder and (c) may be executed in two or
more counterparts which together shall constitute a single agreement.
Article IV and Sections 7.12 and 7.15 are intended to be for the benefit of
those persons described therein and the covenants contained therein may be
enforced by such persons. The parties hereto agree that irreparable damage would
occur in the event that any of the provisions of this Agreement were not
performed in accordance with their specific terms or were otherwise breached. It
is accordingly agreed that the parties shall be entitled to an injunction or
injunctions to prevent breaches of this Agreement and to enforce specifically
the terms and provisions hereof in the Delaware Courts (as defined herein), this
being in addition to any other remedy to which they are entitled at law or in
equity.

    10.5  ASSIGNMENT.  Except as expressly permitted by the terms hereof,
neither this Agreement nor any of the rights, interests or obligations hereunder
shall be assigned by either party hereto without the prior written consent of
the other party.

    10.6  SEVERABILITY.  If any provision of this Agreement, or the application
thereof to any person or circumstance is held invalid or unenforceable, the
remainder of this Agreement, and the application of such provision to other
persons or circumstances, shall not be affected thereby, and to such end, the
provisions of this Agreement are agreed to be severable.

    10.7  CHOICE OF LAW; CONSENT TO JURISDICTION.  All disputes, claims or
controversies arising out of this Agreement, or the negotiation, validity or
performance of this Agreement, or the Transactions shall be governed by and
construed in accordance with the laws of the State of Delaware without regard to
its rules of conflict of laws. Each of Parent, MergerCo and the Company hereby
irrevocably and unconditionally consents to submit to the sole and exclusive
jurisdiction of the courts of the State of

                                      A-39
<PAGE>
Delaware and of the United States of America located in the State of Delaware
(the "DELAWARE COURTS") for any litigation arising out of or relating to this
Agreement, or the negotiation, validity or performance of this Agreement, or the
Transactions (and agrees not to commence any litigation relating thereto except
in such courts), waives any objection to the laying of venue of any such
litigation in the Delaware Courts and agrees not to plead or claim in any
Delaware Court that such litigation brought therein has been brought in any
inconvenient forum. Each of the parties hereto agrees, (a) to the extent such
party is not otherwise subject to service of process in the State of Delaware,
to appoint and maintain an agent in the State of Delaware as such party's agent
for acceptance of legal process, and (b) that service of process may also be
made on such party by prepaid certified mail with a proof of mailing receipt
validated by the United States Postal Service constituting evidence of valid
service. Service made pursuant to (a) or (b) above shall have the same legal
force and effect as if served upon such party personally within the State of
Delaware. For purposes of implementing the parties' agreement to appoint and
maintain an agent for service of process in State of Delaware, each such party
does hereby appoint The Corporation Trust Company, 1209 Orange Street,
Wilmington, New Castle County, Delaware 19801, as such agent.

any of its Subsidiaries to, issue or cause the publication of any press release
or other public announcement with respect to, or otherwise make any public
statement concerning, the transactions contemplated by this Agreement without
the consent of the Company, in the case of a proposed announcement or statement
by Parent, or Parent, in the case of a proposed announcement or statement by the
Company, which consent shall not be unreasonably withheld.

                               FIRST AMENDMENT TO
                          AGREEMENT AND PLAN OF MERGER

    FIRST AMENDMENT TO AGREEMENT AND PLAN OF MERGER (this "Amendment"), dated as
of October 16, 2000, by and among Inverness Medical Technology, Inc., a Delaware
corporation ("Parent"), Terrier Acquisition Corp., a Delaware corporation and a
wholly owned subsidiary of Parent ("MERGERCO"), and Integ Incorporated, a
Minnesota corporation (the "COMPANY"). Capitalized terms used herein without
definition shall have the meanings ascribed to such terms in the Merger
Agreement.

    WHEREAS, Parent, MergerCo and the Company have previously entered into that
certain Agreement and Plan of Merger, dated as of October 3, 2000 (the "Merger
Agreement"); and

    WHEREAS, the parties desire to amend certain provisions of the Merger
Agreement as fully set forth herein.

    NOW THEREFORE, in consideration of the representations, warranties and
covenants contained in this Amendment and the Merger Agreement, the parties
agree as follows:

    1.  AMENDMENT OF SECTION 3.1(c).  Section 3.1(c) of the Merger Agreement is
hereby amended and restated by deleting it in its entirety and substituting the
following:

       "(c)  The "CONVERSION RATIO" shall be the result obtained by dividing the
       Equivalent Parent Common Stock Amount by the number of shares of
       outstanding Company Common Stock immediately prior to the Effective Time
       plus the number of shares of Company Common Stock issuable upon the
       exercise of outstanding Company Options and Company Warrants (as defined
       herein). The "EQUIVALENT PARENT COMMON STOCK AMOUNT" shall be equal to:
       (i) (A) the product of the Average Closing Price multiplied by 1,900,000,
       PLUS (B) the aggregate exercise price of all Company Options and Company
       Warrants outstanding immediately prior to the Effective Time; divided by
       (ii) the Average Closing Price of one share of Parent Common Stock. For
       purposes hereof; the "AVERAGE CLOSING PRICE" will mean the average of the
       closing sale prices of a share of Parent Common Stock on the American
       Stock Exchange ("AMEX") for the five (5) trading days immediately
       preceding the Effective Time."

    2.  Terms and Conditions.  Except as specifically modified herein, all other
terms and conditions of the Merger Agreement shall remain in full force and
effect.

October 3, 2000

The Board of Directors
Integ Incorporated
2800 Patton Road
St. Paul, MN 55113

Members of the Board:

    You have requested our opinion as to the fairness, from a financial point of
view, to the holders of common stock of Integ Incorporated (the "Company") of
the consideration to be received by holders of common stock in the Transaction
described below, pursuant to an Agreement and Plan of Merger, to be dated as of
October 3, 2000 (the "Agreement"), among the Company, Inverness Medical
Technology, Inc. ("Purchaser") and Terrier Acquisition Corp. ("Acquisition"), a
wholly owned subsidiary of the Purchaser. The Agreement provides for the merger
(the "Transaction") of the Company into Acquisition in which shares of common
stock of the Company outstanding will be converted and exchanged for common
stock of the Purchaser (the "Consideration"), as more fully set forth in the
Agreement.

    U.S. Bancorp Piper Jaffray Inc., as a customary part of its investment
banking business, is engaged in the valuation of businesses and their securities
in connection with mergers and acquisitions, underwriting and secondary
distributions of securities, private placements and valuations for estate,
corporate and other purposes. We will receive a fee for providing this opinion.
This opinion fee is not contingent upon the consummation of the Transaction. The
Company has also agreed to indemnify us against certain liabilities in
connection with our services. U.S. Bancorp Piper Jaffray is entitled to
additional fees in the event of consummation of the Transaction. U.S. Bancorp
Piper Jaffray makes a market in Company common stock and provides research
coverage on Company common stock. In the ordinary course of our business, we and
our affiliates may actively trade securities of the Company for our own account
or the account of our customers and, accordingly, may at any time hold a long or
short position in such securities. We have furnished investment banking services
to the Company in the past for which we have received customary fees.

    In arriving at our opinion, we have undertaken such review, analyses and
inquiries as we deemed necessary and appropriate under the circumstances. The
circumstances of the proposed Transaction have limited the scope and nature of
our review and analysis in certain material respects. As a development stage
company, the Company has no historical operating results upon which to base an
analysis as a going concern. The Company has not furnished to us any forecasts
of its future operating results, nor, in light of recent developments involving
its joint development activity with Amira Medical and the Company's current
financial and operating condition, could such forecasts be reasonably prepared
for the Company on a stand alone, going concern basis. Nor have we been
furnished, nor requested to perform, any appraisals or valuations of any
specific assets or liabilities of the Company, including, without limitation,
its technology portfolio.

    In view of the foregoing, we have, with your concurrence, concluded the
principal source of Company value against which the fairness of the proposed
Transaction consideration can reasonably be evaluated is the implied value of
the consideration payable under the terms of that certain Option Agreement (the
"Option Agreement") dated April 2, 1999, between the Company and Amira Medical.
Under the Option Agreement, the Company has the right, under certain
circumstances, to cause the merger of the Company and Amira (the "Amira
Merger"). In the Amira Merger, all outstanding shares of Company common stock
and common stock equivalents outstanding at the time of the Amira Merger would
be exchanged for 2,000,000 shares of Amira Medical common stock and $20 million
in cash.

                                      B-1

    Amira Medical is a privately held company. Amira Medical does not provide
its historical or forecast results of operations to the public, nor has such
information been provided by Amira Medical to the Company or U.S. Bancorp Piper
Jaffray. The Company has compiled a forecast for Amira Medical for the calendar
years ending 2004 and furnished this forecast to us for use in evaluating the
implied value of the Company arising out of a possible Amira Merger. The Company
furnished to U.S. Bancorp Piper Jaffray information from which assumptions were
developed regarding the possible timing of an initial public offering of Amira
Medical common stock. The Company also furnished to us other information
concerning a recent financing transaction involving Amira Medical capital stock.
Amira Medical has not reviewed or otherwise verified the accuracy or
completeness of any of the foregoing information. We have, with your consent,
relied upon and assumed the accuracy and completeness of this information
furnished to us by management of the Company, and have assumed no responsibility
for the independent verification of such information. We have relied upon the
assurances of management of the Company that the information provided to us as
set forth above has been prepared on a reasonable basis and reflects the best
currently available estimates, and that they are not aware of any information or
facts that would make the information so provided to us incomplete or
misleading. We have assumed the Option Agreement remains in full force and
effect, without amendment, and is enforceable by the parties thereto in
accordance with its terms.

    In addition to the foregoing, for purposes of this opinion we have reviewed,
among other things, (i) the draft dated October 1, 2000 of the Agreement,
(ii) certain publicly available financial, operating and business information
related to the Company, (iii) certain publicly available market and securities
data of the Company, (iv) the Company's License and Development Agreement, dated
April 2, 1999, with Amira Medical, (v) certain publicly available financial,
operating and business information relative to the Purchaser, (vi) certain
forecast financial information of the Company and Purchaser as a combined
company, furnished by the management of the Company and Purchaser, and
(vii) certain publicly available market and securities data of the Purchaser. We
had discussions with members of the management of (a) the Company concerning the
financial condition, current operating results and business outlook for each of
the Company, Amira and Purchaser on a stand-alone basis and the combined company
resulting from the Transaction and from the Amira Merger contemplated by the
Option Agreement, and (b) Purchaser concerning the financial condition, current
operating results and business outlook for Purchaser and the combined company
resulting from the Transaction and the Purchaser's plans relating to such
combined company.

    We have relied upon and assumed the accuracy and completeness of the
information provided to us by the Company and Purchaser or otherwise made
available to us, and have not assumed responsibility for the independent
verification of such information. We have relied upon the assurances of the
managements of the Company and Purchaser that the information provided to us by
the Company and Purchaser has been prepared on a reasonable basis, and, with
respect to business outlook information, reflects the best currently available
estimates, and that they are not aware of any information or facts that would
make the information provided to us incomplete or misleading.

    We have also assumed that the Transaction will constitute a "reorganization"
within the meaning of Section 368(a) of the Code and that the Transaction will
be treated as a purchase for accounting purposes. In addition, in arriving at
our opinion, we have assumed that, in the course of obtaining the necessary
regulatory approvals for the Transaction, no restrictions, including any
divestiture requirements, will be imposed that would have a material adverse
effect on the contemplated benefits of the Transaction.

    This opinion is necessarily based upon the information available to us and
facts and circumstances as they exist and are subject to evaluation on the date
hereof; events occurring after the date hereof could materially affect the
assumptions used in preparing this opinion. We are not expressing any opinion
herein as to the price at which shares of Company common stock or Purchaser
common stock have traded or may trade at any future time. We have not undertaken
to reaffirm or revise this opinion

                                      B-2
<PAGE>
or otherwise comment upon any events occurring after the date hereof and do not
have any obligation to update, revise or reaffirm this opinion.

    This opinion is directed to the Board of Directors of the Company and is not
intended to be and does not constitute a recommendation to any shareholder of
the Company. Other than one party which we were authorized to contact and did
contact, we have not been authorized by the Board of Directors of the Company to
solicit other purchasers of the Company or alternative transactions to the
Transaction. We were not requested to opine as to, and this opinion does not
address, the basic business decision to proceed with or effect the Transaction
or any alternative transaction, including without limitation, the Amira Merger.
This opinion shall not be published or otherwise used, nor shall any public
references to us be made without our prior written approval.

    Our opinion addresses solely the fairness of the Consideration to be paid to
holders of the common stock of the Company in the Transaction pursuant to the
Agreement and does not address any other term or agreement relating to the
Transaction. Without limiting the generality of the foregoing, we have made no
evaluation of the terms pursuant to which outstanding shares of Series B
Preferred Stock will be redeemed or pursuant to which Purchaser will extend
financing to the Company in accordance with a proposed loan agreement.

    Based upon and subject to the foregoing and based upon such other factors as
we consider relevant, it is our opinion that the proposed Consideration to be
received in the Transaction pursuant to the Agreement for the common stock of
the Company is fair, from a financial point of view, to the holders of common
stock of the Company as of the date hereof.

                                          Sincerely,

                                          U.S. BANCORP PIPER JAFFRAY INC.

               MINNESOTA STATUTES, SECTIONS 302A.471 AND 302A.471
                     REGARDING DISSENTER'S APPRAISAL RIGHTS

302A.471  RIGHTS OF DISSENTING SHAREHOLDERS.

    Subdivision 1.  ACTIONS CREATING RIGHTS.  A shareholder of a corporation may
dissent from, and obtain payment for the fair value of the shareholder's shares
in the event of, any of the following corporate actions:

    (a) An amendment of the articles that materially and adversely affects the
rights or preferences of the shares of the dissenting shareholder in that it:

        (1) alters or abolishes a preferential right of the shares;

        (2) creates, alters, or abolishes a right in respect of the redemption
    of the shares, including a provision respecting a sinking fund for the
    redemption or repurchase of the shares;

        (3) alters or abolishes a preemptive right of the holder of the shares
    to acquire shares, securities other than shares, or rights to purchase
    shares or securities other than shares;

        (4) excludes or limits the right of a shareholder to vote on a matter,
    or to cumulate votes, except as the right may be excluded or limited through
    the authorization or issuance of securities of an existing or new class or
    series with similar or different voting rights; except that an amendment to
    the articles of an issuing public corporation that provides that
    section 302A.671 does not apply to a control share acquisition does not give
    rise to the right to obtain payment under this section;

    (b) A sale, lease, transfer, or other disposition of all or substantially
all of the property and assets of the corporation, but not including a
transaction permitted without shareholder approval in section 302A.661,
subdivision 1, or a disposition in dissolution described in section 302A.725,
subdivision 2, or a disposition pursuant to an order of a court, or a
disposition for cash on terms requiring that all or substantially all of the net
proceeds of disposition be distributed to the shareholders in accordance with
their respective interests within one year after the date of disposition;

    (c) A plan of merger, whether under this chapter or under chapter 322B, to
which the corporation is a constituent organization, except as provided in
subdivision 3;

    (d) A plan of exchange, whether under this chapter or under chapter 322B, to
which the corporation is a party as the corporation whose shares will be
acquired by the acquiring corporation, if the shares of the shareholder are
entitled to be voted on the plan; or

    (e) Any other corporate action taken pursuant to a shareholder vote with
respect to which the articles, the bylaws, or a resolution approved by the board
directs that dissenting shareholders may obtain payment for their shares.

    Subd. 2.  BENEFICIAL OWNERS.  (a) A shareholder shall not assert dissenters'
rights as to less than all of the shares registered in the name of the
shareholder, unless the shareholder dissents with respect to all the shares that
are beneficially owned by another person but registered in the name of the
shareholder and discloses the name and address of each beneficial owner on whose
behalf the shareholder dissents. In that event, the rights of the dissenter
shall be determined as if the shares as to which the shareholder has dissented
and the other shares were registered in the names of different shareholders.

    (b) A beneficial owner of shares who is not the shareholder may assert
dissenters' rights with respect to shares held on behalf of the beneficial
owner, and shall be treated as a dissenting

                                      C-1
<PAGE>
shareholder under the terms of this section and section 302A.473, if the
beneficial owner submits to the corporation at the time of or before the
assertion of the rights a written consent of the shareholder.

    Subd. 3.  RIGHTS NOT TO APPLY.  (a) Unless the articles, the bylaws, or a
resolution approved by the board otherwise provide, the right to obtain payment
under this section does not apply to a shareholder of the surviving corporation
in a merger, if the shares of the shareholder are not entitled to be voted on
the merger.

    (b) If a date is fixed according to section 302A.445, subdivision 1, for the
determination of shareholders entitled to receive notice of and to vote on an
action described in subdivision 1, only shareholders as of the date fixed, and
beneficial owners as of the date fixed who hold through shareholders, as
provided in subdivision 2, may exercise dissenters' rights.

    Subd. 4.  OTHER RIGHTS.  The shareholders of a corporation who have a right
under this section to obtain payment for their shares do not have a right at law
or in equity to have a corporate action described in subdivision 1 set aside or
rescinded, except when the corporate action is fraudulent with regard to the
complaining shareholder or the corporation.

302A.473  PROCEDURES FOR ASSERTING DISSENTERS' RIGHTS.

    Subdivision 1.  DEFINITIONS.  (a) For purposes of this section, the terms
defined in this subdivision have the meanings given them.

    (b) "Corporation" means the issuer of the shares held by a dissenter before
the corporate action referred to in section 302A.471, subdivision 1 or the
successor by merger of that issuer.

    (c) "Fair value of the shares" means the value of the shares of a
corporation immediately before the effective date of the corporate action
referred to in section 302A.471, subdivision 1.

    (d) "Interest" means interest commencing five days after the effective date
of the corporate action referred to in section 302A.471, subdivision 1, up to
and including the date of payment, calculated at the rate provided in
section 549.09 for interest on verdicts and judgments.

    Subd. 2.  NOTICE OF ACTION.  If a corporation calls a shareholder meeting at
which any action described in section 302A.471, subdivision 1 is to be voted
upon, the notice of the meeting shall inform each shareholder of the right to
dissent and shall include a copy of section 302A.471 and this section and a
brief description of the procedure to be followed under these sections.

    Subd. 3.  NOTICE OF DISSENT.  If the proposed action must be approved by the
shareholders, a shareholder who is entitled to dissent under section 302A.471
and who wishes to exercise dissenters' rights must file with the corporation
before the vote on the proposed action a written notice of intent to demand the
fair value of the shares owned by the shareholder and must not vote the shares
in favor of the proposed action.

    Subd. 4.  NOTICE OF PROCEDURE; DEPOSIT OF SHARES.  (a) After the proposed
action has been approved by the board and, if necessary, the shareholders, the
corporation shall send to all shareholders who have complied with subdivision 3
and to all shareholders entitled to dissent if no shareholder vote was required,
a notice that contains:

        (1) The address to which a demand for payment and certificates of
    certificated shares must be sent in order to obtain payment and the date by
    which they must be received;

        (2) Any restrictions on transfer of uncertificated shares that will
    apply after the demand for payment is received;

                                      C-2
<PAGE>
        (3) A form to be used to certify the date on which the shareholder, or
    the beneficial owner on whose behalf the shareholder dissents, acquired the
    shares or an interest in them and to demand payment; and

        (4) A copy of section 302A.471 and this section and a brief description
    of the procedures to be followed under these sections.

    (b) In order to receive the fair value of the shares, a dissenting
shareholder must demand payment and deposit certificated shares or comply with
any restrictions on transfer of uncertificated shares within 30 days after the
notice required by paragraph (a) was given, but the dissenter retains all other
rights of a shareholder until the proposed action takes effect.

    Subd. 5.  PAYMENT; RETURN OF SHARES.  (a) After the corporate action takes
effect, or after the corporation receives a valid demand for payment, whichever
is later, the corporation shall remit to each dissenting shareholder who has
complied with subdivisions 3 and 4 the amount the corporation estimates to be
the fair value of the shares, plus interest, accompanied by:

        (1) the corporation's closing balance sheet and statement of income for
    a fiscal year ending not more than 16 months before the effective date of
    the corporate action, together with the latest available interim financial
    statements;

        (2) an estimate by the corporation of the fair value of the shares and a
    brief description of the method used to reach the estimate; and

        (3) a copy of section 302A.471 and this section, and a brief description
    of the procedure to be followed in demanding supplemental payment.

    (b) The corporation may withhold the remittance described in paragraph (a)
from a person who was not a shareholder on the date the action dissented from
was first announced to the public or who is dissenting on behalf of a person who
was not a beneficial owner on that date. If the dissenter has complied with
subdivisions 3 and 4, the corporation shall forward to the dissenter the
materials described in paragraph (a), a statement of the reason for withholding
the remittance, and an offer to pay to the dissenter the amount listed in the
materials if the dissenter agrees to accept that amount in full satisfaction.
The dissenter may decline the offer and demand payment under subdivision 6.
Failure to do so entitles the dissenter only to the amount offered. If the
dissenter makes demand, subdivisions 7 and 8 apply.

    (c) If the corporation fails to remit payment within 60 days of the deposit
of certificates or the imposition of transfer restrictions on uncertificated
shares, it shall return all deposited certificates and cancel all transfer
restrictions. However, the corporation may again give notice under subdivision 4
and require deposit or restrict transfer at a later time.

    Subd. 6.  SUPPLEMENTAL PAYMENT; DEMAND.  If a dissenter believes that the
amount remitted under subdivision 5 is less than the fair value of the shares
plus interest, the dissenter may give written notice to the corporation of the
dissenter's own estimate of the fair value of the shares, plus interest, within
30 days after the corporation mails the remittance under subdivision 5, and
demand payment of the difference. Otherwise, a dissenter is entitled only to the
amount remitted by the corporation.

    Subd. 7.  PETITION; DETERMINATION.  If the corporation receives a demand
under subdivision 6, it shall, within 60 days after receiving the demand, either
pay to the dissenter the amount demanded or agreed to by the dissenter after
discussion with the corporation or file in court a petition requesting that the
court determine the fair value of the shares, plus interest. The petition shall
be filed in the county in which the registered office of the corporation is
located, except that a surviving foreign corporation that receives a demand
relating to the shares of a constituent domestic corporation shall file the
petition in the county in this state in which the last registered office of the
constituent corporation was located. The petition shall name as parties all
dissenters who have demanded payment

                                      C-3
<PAGE>
under subdivision 6 and who have not reached agreement with the corporation. The
corporation shall, after filing the petition, serve all parties with a summons
and copy of the petition under the rules of civil procedure. Nonresidents of
this state may be served by registered or certified mail or by publication as
provided by law. Except as otherwise provided, the rules of civil procedure
apply to this proceeding. The jurisdiction of the court is plenary and
exclusive. The court may appoint appraisers, with powers and authorities the
court deems proper, to receive evidence on and recommend the amount of the fair
value of the shares. The court shall determine whether the shareholder or
shareholders in question have fully complied with the requirements of this
section, and shall determine the fair value of the shares, taking into account
any and all factors the court finds relevant, computed by any method or
combination of methods that the court, in its discretion, sees fit to use,
whether or not used by the corporation or by a dissenter. The fair value of the
shares as determined by the court is binding on all shareholders, wherever
located. A dissenter is entitled to judgment in cash for the amount by which the
fair value of the shares as determined by the court, plus interest, exceeds the
amount, if any, remitted under subdivision 5, but shall not be liable to the
corporation for the amount, if any, by which the amount, if any, remitted to the
dissenter under subdivision 5 exceeds the fair value of the shares as determined
by the court, plus interest.

    Subd. 8.  COSTS; FEES; EXPENSES.  (a) The court shall determine the costs
and expenses of a proceeding under subdivision 7, including the reasonable
expenses and compensation of any appraisers appointed by the court, and shall
assess those costs and expenses against the corporation, except that the court
may assess part or all of those costs and expenses against a dissenter whose
action in demanding payment under subdivision 6 is found to be arbitrary,
vexatious, or not in good faith.

    (b) If the court finds that the corporation has failed to comply
substantially with this section, the court may assess all fees and expenses of
any experts or attorneys as the court deems equitable. These fees and expenses
may also be assessed against a person who has acted arbitrarily, vexatiously, or
not in good faith in bringing the proceeding, and may be awarded to a party
injured by those actions.

    (c) The court may award, in its discretion, fees and expenses to an attorney
for the dissenters out of the amount awarded to the dissenters, if any.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

    Section 145 of the Delaware General Corporation Law provides that a
corporation may indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative, other than
an action by or in the right of the corporation, by reason of the fact that the
person is or was a director, officer, employee or agent of the corporation or is
or was serving at the corporation's request as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, against expenses, including attorneys' fees, judgments, fines and
amounts paid in settlement actually and reasonably incurred by the person in
connection with the action, suit or proceeding if the person acted in good faith
and in a manner the person reasonably believed to be in or not opposed to the
best interests of the corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe the person's conduct was
unlawful. The power to indemnify applies to actions brought by or in the right
of the corporation as well, but only to the extent of expenses, including
attorneys' fees but excluding judgments, fines and amounts paid in settlement,
actually and reasonably incurred by the person in connection with the defense or
settlement of the action or suit. And with the further limitation that in these
actions, no indemnification shall be made in the event of any adjudication of
negligence or misconduct in the performance of the person's duties to the
corporation, unless a court believes that in light of all the circumstances
indemnification should apply.

    Article V of Inverness' bylaws provides that Inverness shall, to the extent
legally permitted, indemnify each person who was or is a party or is threatened
to be made a party to any threatened, pending or completed action, suit or
proceeding by reason of the fact that such person is or was, or has agreed to
become, a director or officer of Inverness, or is or was serving, or has agreed
to serve, at the request of Inverness, as a director, officer or trustee of, or
in a similar capacity with, another corporation, partnership, joint venture,
trust or other enterprises. The indemnification provided for in Article V is
expressly not exclusive of any other rights to which those seeking
indemnification may be entitled under any law, agreement or vote of stockholders
or disinterested directors or otherwise, and shall inure to the benefit of the
heirs, executors and administrators of such persons.

    Section 145(g) of the Delaware General Corporation Law and Article V of the
bylaws of Inverness provide that Inverness shall have the power to purchase and
maintain insurance on behalf of its officers, directors, employees and agents,
against any liability asserted against and incurred by such persons in any such
capacity.

    Inverness has obtained insurance covering its directors and officers against
losses and insuring Inverness against certain of its obligations to indemnify
its directors and officers.

    Section 102(b)(7) of the General Corporation Law of the State of Delaware
provides that a corporation may eliminate or limit the personal liability of a
director to the corporation or its stockholders for monetary damages for breach
of fiduciary duty as a director, provided that such provisions shall not
eliminate or limit the liability of a director (i) for any breach of the
director's duty of loyalty to the corporation or its stockholders, (ii) for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under section 174 of the General Corporation Law
of the State of Delaware, or (iv) for any transaction from which the director
derived an improper personal benefit. No such provision shall eliminate or limit
the liability of a director for any act or omission occurring prior to the date
when such provision becomes effective.

    Pursuant to the Delaware General Corporation Law, Article VII of the
certificate of incorporation of Inverness eliminates a director's personal
liability for monetary damages to Inverness and its stockholders for breach of
fiduciary duty as a director, except in circumstances involving a breach of

                                      II-1

the director's duty of loyalty to Inverness or its stockholders, acts or
omissions not in good faith, intentional misconduct, knowing violations of the
law, self-dealing or the unlawful payment of dividends or repurchase of stock.

ITEM 21.  EXHIBITS AND FINANCIAL STATEMENT SCHEDULES

    (a) See Exhibit Index immediately following the signature page.


    (b) Not applicable.


    (c) Opinion of U.S. Bancorp Piper Jaffray (included as Annex B to the proxy
statement and prospectus which is a part of this Registration Statement).

ITEM 22.  UNDERTAKINGS

    (a)(1) The undersigned registrant hereby undertakes as follows: that prior
to any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.

    (2) The registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (a)(1) immediately preceding, or (ii) that purports to
meet the requirements of section 10(a)(3) of the Securities Act of 1933 and is
used in connection with an offering of securities subject to Rule 415, will be
filed as a part of an amendment to the registration statement and will not be
used until such amendment is effective, and that, for purposes of determining
any liability under the Securities Act of 1933, each such post-effective
amendment shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial BONA FIDE offering thereof.

    (3) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers or persons controlling the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been informed that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
of 1933 and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act of 1933 and will be governed by the final adjudication of such issue.

    (b) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.


    (c) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the Registration Statement when it became effective.
