    For more information about trading in Everest Medical stock, see Section 8
of this Offer to Purchase.

CONSEQUENCES OF OUR OFFER

    - Our purchase of shares of common stock pursuant to our offer will reduce
      the number of holders of these shares and the number of shares that might
      otherwise trade publicly. After the completion of our offer, common stock
      may no longer qualify for inclusion in The Nasdaq Stock Market due to a
      decrease in the number of holders of common stock to less than 300 or in
      the number of publicly held shares to less than 100,000, among other
      things. If the common stock no longer meets the requirements of the NASD
      for continued inclusion in The Nasdaq Stock Market or The Nasdaq SmallCap
      Stock Market, as the case may be, the market for your shares could be
      adversely affected.

    - We intend to seek to cause Everest Medical to apply for termination of
      registration of its common stock under the Securities Exchange Act of 1934
      as soon after the completion of our offer as the requirements for that
      termination are met, that is, if there are fewer than 300 holders of
      record of common stock and common stock is not listed on a national
      securities exchange.

    - If you have questions about our offer, you may contact MacKenzie

Minnesota corporation (the "Company"), for the consideration provided below and

together with any amendments or supplements thereto, collectively constitute the
"Offer"):

    - all outstanding shares of common stock (the "Common Shares"), par value
      $.01 per share, at $4.85 per Common Share (the "Common Share Offer
      Price"), net to the seller, in cash;

    - all outstanding shares of Series A Convertible Preferred Stock (the
      "Series A Shares"), par value $.01 per share, at an amount per share equal
      to the product of (1) the number of Common Shares into which each such
      Series A Share is convertible multiplied by (2) the Common Share Offer
      Price, or $4.85 per Series A Share ("the Series A Offer Price"), net to
      the seller, in cash;

    - all outstanding shares of Series B 8% Convertible Preferred Shares (the
      "Series B Shares"), $.01 per share, at an amount per share equal to the

      to the seller, in cash; and

    - all outstanding shares of Series D 10% Convertible Redeemable Preferred

(the "Information Agent"), incurred in connection with the Offer. See

    THE BOARD OF DIRECTORS OF THE COMPANY, AFTER RECEIVING THE UNANIMOUS
RECOMMENDATION OF THE SPECIAL COMMITTEE OF THE BOARD OF DIRECTORS, HAS
UNANIMOUSLY APPROVED THE OFFER AND THE MERGER (AS DEFINED BELOW) AND DETERMINED
THAT THE TERMS OF THE OFFER AND THE MERGER ARE FAIR TO, AND IN THE BEST
INTERESTS OF, THE SHAREHOLDERS OF THE COMPANY, AND UNANIMOUSLY RECOMMENDS THAT
SHAREHOLDERS OF THE COMPANY ACCEPT THE OFFER AND TENDER THEIR SHARES.

    The Company has advised the Purchaser that Dougherty & Company LLC has
delivered to the Board of Directors of the Company its written opinion dated
February 22, 2000 to the effect that, subject to and

                                       1
<PAGE>
based upon the matters described in the opinion, as of the date of such opinion,
the Offer Price to be received by the holders of the Common Shares, the
Series A Shares, the Series B Shares, the Series C Shares, and the Series D
Shares, respectively, pursuant to the Offer and the Merger is fair to such
holders from a financial point of view. That opinion is set forth in full as an
exhibit to the Company's Solicitation/ Recommendation Statement on
Schedule 14D-9 (the "Schedule 14D-9" or the "Statement"), which is being mailed
to you with this Offer to Purchase. YOU ARE URGED TO, AND SHOULD, READ SUCH
OPINION CAREFULLY IN ITS ENTIRETY.

    THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, THERE BEING VALIDLY
TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION DATE (AS DEFINED IN
SECTION 1) THAT NUMBER OF SHARES THAT WOULD CONSTITUTE AT LEAST A MAJORITY OF
THE OUTSTANDING SHARES (DETERMINED AS OF THE EXPIRATION DATE ON A FULLY DILUTED
BASIS, TAKING INTO ACCOUNT ALL SHARES ISSUABLE ON EXERCISE OR CONVERSION OF ALL
OPTIONS, WARRANTS AND ANY OTHER RIGHTS TO ACQUIRE SHARES OUTSTANDING ON THE
EXPIRATION DATE) (THE "MINIMUM CONDITION"). THE PURCHASER RESERVES THE RIGHT
(SUBJECT TO THE APPLICABLE RULES AND REGULATIONS OF THE SECURITIES AND EXCHANGE
COMMISSION (THE "COMMISSION")), WHICH IT PRESENTLY HAS NO INTENTION OF
EXERCISING, TO WAIVE OR REDUCE THE MINIMUM CONDITION AND TO ELECT TO PURCHASE,
PURSUANT TO THE OFFER, LESS THAN THE NUMBER OF SHARES REQUIRED TO SATISFY THE
MINIMUM CONDITION. SEE SECTIONS 1 AND 14.

    The Company has informed the Purchaser that, as of February 23, 2000, there
were 7,728,965 Common Shares issued and outstanding, 462,937 Series A Shares
issued and outstanding, 597,273 Series B Shares issued and outstanding, 410,906
Series C Shares issued and outstanding, and 466,500 Series D Shares issued and
outstanding. The Company also has informed the Purchaser that, as of
February 23, 2000, there were 1,964,051 shares reserved for issuance upon the
exercise of outstanding options, warrants, and other rights to acquire Shares.
Accordingly, based on the foregoing assumptions, the Minimum Condition will be
satisfied if at least 5,826,947 Shares, or approximately 60.3% of the 9,666,581
outstanding Shares as of February 23, 2000, are validly tendered and not
withdrawn prior to the Expiration Date. Once the Minimum Condition has been
satisfied and the Purchaser accepts for payment Shares tendered pursuant to the
Offer, the Purchaser will be able to elect a majority of the members of the
Company's Board of Directors and approve the Merger at a meeting of shareholders
of the Company and, if the shares tendered pursuant to the Offer constitute at
least 90% of each class of Shares outstanding at such time, to effect the Merger
without holding a meeting of the shareholders of the Company.

    The Offer is being made pursuant to the Agreement and Plan of Merger, dated
as of February 23, 2000 (the "Merger Agreement"), among Parent, the Purchaser
and the Company, pursuant to which, following the consummation of the Offer and
the satisfaction or waiver of certain conditions, the Company will be merged
with and into the Purchaser (the "Merger"), with the Purchaser surviving the
Merger (as such, the "Surviving Corporation") as a subsidiary of Parent. In the
Merger, each Share issued and outstanding immediately prior to the Merger (other
than Shares (1) owned by Parent or the Purchaser, (2) remaining outstanding held
by any subsidiary of Parent or (3) owned by shareholders, if any, who are
entitled to and who properly exercise dissenters' rights under Minnesota law)
will be converted into the right to receive $4.85 in cash, without interest, the
same per share consideration as the Offer Price (the "Merger Consideration").
See Section 12.

    The Merger is subject to a number of conditions, including approval by
shareholders of the Company, if such approval is required by applicable law. If
the Purchaser acquires 90% or more of each class of the outstanding Shares
pursuant to the Offer or otherwise, the Purchaser will effect the Merger
pursuant to the short-form merger provisions of the Delaware General Corporation
Law (the "DGCL") and the Minnesota Business Corporation Act (the "MBCA"),
without any action by any other shareholder of the Company. See Section 12.

    The Merger Agreement is more fully described in Section 12. Certain Federal
income tax consequences of the sale of Shares pursuant to the Offer are
described in Section 5.

                                THE TENDER OFFER

1.  TERMS OF THE OFFER

    Upon the terms and subject to the conditions of the Offer (including if the
Offer is extended or amended, the terms and conditions of any such extension or
amendment), the Purchaser will accept for payment and pay for all Shares validly
tendered prior to the Expiration Date and not theretofore withdrawn in
accordance with Section 3. The term "Expiration Date" means 12:00 noon, New York
City time, on April 13, 2000, unless the Purchaser shall have extended the
period of time during which the Offer is open, in which event the term
"Expiration Date" shall mean the latest time and date at which the Offer, as so
extended by the Purchaser, shall expire.

    Subject to applicable rules and regulations of the Securities and Exchange
Commission (the "Commission"), and the terms and conditions of the Merger
Agreement, the Purchaser expressly reserves the right, in its sole discretion,
at any time and from time to time, and regardless of whether or not any of the
events set forth in Section 14 hereof shall have occurred or shall have been
determined by the Purchaser to have occurred, (1) to extend the period of time
during which the Offer is open, and thereby delay acceptance for payment of and
the payment for any Shares, by giving oral or written notice of such extension
to the Depositary and (2) to amend the Offer in any other respect by giving oral
or written notice of such amendment to the Depositary. UNDER NO CIRCUMSTANCES
WILL INTEREST BE PAID ON THE PURCHASE PRICE OF THE SHARES TO BE PAID BY THE
PURCHASER, REGARDLESS OF ANY EXTENSION OF THE OFFER OR ANY DELAY IN MAKING SUCH
PAYMENT.

    If by 12:00 noon, New York City time, on April 13, 2000 (or any other date
or time then set as the Expiration Date), any or all conditions to the Offer
have not been satisfied or waived, the Purchaser reserves the right (but shall
not be obligated), subject to the terms and conditions contained in the Merger
Agreement and to the applicable rules and regulations of the Commission, (1) to
terminate the Offer and not accept for payment any Shares and return all
tendered Shares to tendering shareholders, (2) to waive one or more of the
unsatisfied conditions and, subject to complying with the terms of the Merger
Agreement and the applicable rules and regulations of the Commission, accept for
payment and pay for all Shares validly tendered prior to the Expiration Date and
not theretofore withdrawn, (3) to extend the Offer and, subject to the right of
shareholders to withdraw Shares until the Expiration Date, retain the Shares
that have been tendered during the period or periods for which the Offer is
extended, (4) to amend the Offer, or (5) to accept for payment all Shares
validly tendered as of the Expiration Date and provide a subsequent offering
period of three business days to 20 business days after the completion of the
initial offering period of the Offer, as may be extended (the "Initial Offering
Period"), as defined and further described below.

    There can be no assurance that the Purchaser will exercise its right to
extend the Offer. Any extension, waiver, amendment or termination will be
followed as promptly as practicable by public announcement. In the case of an
extension, Rule 14e-l(d) under the Securities Exchange Act of 1934 (the
"Exchange Act") requires that the announcement be issued no later than
9:00 a.m., New York City time, on the next business day after the previously
scheduled Expiration Date. Subject to applicable law (including
Rule 14d-4(d)(1) under the Exchange Act which requires that any material change
in the information published, sent or given to shareholders in connection with
the Offer be promptly disseminated to shareholders in a manner reasonably
designed to inform shareholders of such change), and without limiting the manner
in which the Purchaser may choose to make any public announcement, the Purchaser
currently intends to make such public announcement by issuing a press release to
the Dow Jones News Service and making any appropriate filing with the
Commission.

    Pursuant to the Merger Agreement, the Purchaser may, without the prior
consent of the Company, extend the Offer, particularly, but not exclusively
(1) if at the Expiration Date any of the conditions to the Purchaser's
obligations to accept Shares for payment are not satisfied or waived, until such
time as such conditions are satisfied or waived, (2) for any period required by
any rule, regulation, interpretation or position of the Commission or the staff
thereof applicable to the Offer or any period required by

                                       3
<PAGE>
applicable law and (3) on one or more occasions for an aggregate period of not
more than 10 business days beyond the latest expiration date that would
otherwise be permitted under clause (1) or (2) of this sentence, if on such
expiration date the Minimum Condition shall not be satisfied. For purposes of
the Offer, a "business day" means any day other than a Saturday, Sunday or a
Federal holiday and consists of the time period from 12:01 a.m. through 12:00
Midnight, New York City time.

    If the Purchaser extends the Offer or if the Purchaser (whether before or
after its acceptance for payment of Shares) is delayed in its acceptance for
payment of or payment for Shares or it is unable to pay for Shares pursuant to
the Offer for any reason, then, without prejudice to the Purchaser's rights
under the Offer, the Depositary may retain tendered Shares on behalf of the
Purchaser, and such Shares may not be withdrawn except to the extent tendering
shareholders are entitled to withdrawal rights as described in Section 3.
However, the ability of the Purchaser to delay the payment for Shares that the
Purchaser has accepted for payment is limited by Rule 14e-1(c) under the
Exchange Act, which requires that a bidder pay the consideration offered or
return the securities deposited by or on behalf of holders of securities
promptly after the termination or withdrawal of such bidder's offer.

    The Purchaser may also elect to provide a subsequent offering period of
three business days to 20 business days after the Expiration Date, pursuant to
Rule 14d-11 under the Exchange Act (a "Subsequent Offering Period"). If the
Purchaser elects to provide a Subsequent Offering Period, the subsequent offer
will be for all outstanding Shares and the Purchaser will immediately accept and
promptly pay for all Shares as they are tendered during such Subsequent Offering
Period, offering the same form and amount of consideration offered by the
Purchaser for validly tendered Shares during the initial offering period. No
withdrawal rights shall apply during any Subsequent Offering Period in
accordance with Rule 14d-7(a)(2) under the Exchange Act.

    If the Purchaser makes a material change in the terms of the Offer or the
information concerning the Offer or waives a material condition of the Offer,
the Purchaser will disseminate additional tender offer materials and extend the
Offer to the extent required by the Exchange Act (including Rule 14d-4(d)(1) and
14e-1). The minimum period during which an offer must remain open following
material changes in the terms of the offer or information concerning the offer,
other than a change in price or a change in the percentage of securities sought,
will depend upon the facts and circumstances then existing, including the
relative materiality of the changed terms or information. With respect to a
change in price or a change in the percentage of securities sought, a minimum
period of 10 business days is generally required to allow for adequate
dissemination to shareholders.

    CONSUMMATION OF THE OFFER IS CONDITIONED UPON SATISFACTION OF THE MINIMUM
CONDITION AND THE OTHER CONDITIONS SET FORTH IN SECTION 14.  Subject to the
terms and conditions contained in the Merger Agreement, the Purchaser reserves
the right (but shall not be obligated) to waive any or all such conditions. The
Company has provided the Purchaser with the Company's shareholder lists and
security position listings for the purpose of disseminating the Offer to holders
of the Shares. This Offer to Purchase, the related Letter of Transmittal and
other relevant materials will be mailed by the Purchaser to record holders of
Shares and will be furnished by the Purchaser to brokers, dealers, banks, trust
companies and similar persons whose names, or the names of whose nominees,
appear on the shareholder lists or, if applicable, who are listed as
participants in a clearing agency's security position listing, for subsequent
transmittal to beneficial owners of Shares.

2.  PROCEDURE FOR TENDERING SHARES

    VALID TENDER OF COMMON SHARES.  For a shareholder to tender Common Shares
validly pursuant to the Offer, either (1) a properly completed and duly executed
Letter of Transmittal (or facsimile thereof), together with any required
signature guarantees, or in the case of a book-entry transfer, an Agent's
Message (as defined in the second succeeding paragraph), and any other documents
required by the Letter of Transmittal, must be received by the Depositary at one
of its addresses set forth on the back cover of this Offer to Purchase prior to
the Expiration Date and either certificates for tendered Common Shares must be
received by the Depositary at one of such addresses or such Common Shares must
be delivered

                                       4
<PAGE>
pursuant to the procedure for book-entry transfer set forth below (and a
Book-Entry Confirmation (as defined in the next paragraph) received by the
Depositary), in each case, prior to the Expiration Date, or (2) the tendering
shareholder must comply with the guaranteed delivery procedure set forth below.

    The Depositary will establish an account with respect to the Common Shares
at The Depository Trust Company (the "Book-Entry Transfer Facility") for
purposes of the Offer within two business days after the date of this Offer to
Purchase. Any financial institution that is a participant in the Book-Entry
Transfer Facility's system may make book-entry delivery of Common Shares by
causing the Book-Entry Transfer Facility to transfer such Common Shares into the
Depositary's account in accordance with the Book-Entry Transfer Facility's
procedures for such transfer. However, although delivery of Common Shares may be
effected through book-entry transfer into the Depositary's account at the
Book-Entry Transfer Facility, the Letter of Transmittal (or facsimile thereof),
properly completed and duly executed, with any required signature guarantees, or
an Agent's Message, and any other required documents, must, in any case, be
transmitted to, and received by, the Depositary at one of its addresses set
forth on the back cover of this Offer to Purchase prior to the Expiration Date,
or the tendering shareholder must comply with the guaranteed delivery procedure
described below. The confirmation of a book-entry transfer of Common Shares into
the Depositary's account at the Book-Entry Transfer Facility as described above
is referred to herein as a "Book-Entry Confirmation." DELIVERY OF THE LETTER OF
TRANSMITTAL OR ANY OTHER REQUIRED DOCUMENTS TO THE BOOK-ENTRY TRANSFER FACILITY
IN ACCORDANCE WITH THE BOOK-ENTRY TRANSFER FACILITY'S PROCEDURES DOES NOT
CONSTITUTE DELIVERY TO THE DEPOSITARY.

    The term "Agent's Message" means a message transmitted by the Book-Entry
Transfer Facility to, and received by, the Depositary and forming a part of a
Book-Entry Confirmation, which states that the Book-Entry Transfer Facility has
received an express acknowledgment from the participant in the Book-Entry
Transfer Facility tendering the Common Shares that such participant has received
and agrees to be bound by the terms of the Letter of Transmittal and that the
Purchaser may enforce such agreement against the participant.

    VALID TENDER OF SERIES A SHARES, SERIES B SHARES, SERIES C SHARES AND
SERIES D SHARES.  For a shareholder to tender Series A Shares, Series B Shares,
Series C Shares and Series D Shares validly pursuant to the Offer, either (1) a
properly completed and duly executed Letter of Transmittal (or facsimile
thereof), together with any required signature guarantees, any other documents
required by the Letter of Transmittal and certificates for tendered Series A
Shares, Series B Shares, Series C Shares and Series D Shares must be received by
the Depositary at one of its addresses set forth on the back cover of this Offer
to Purchase prior to the Expiration Date or (2) the tendering shareholder must
comply with the guaranteed delivery procedure set forth below. A SHAREHOLDER MAY
NOT VALIDLY TENDER SERIES A SHARES, SERIES B SHARES, SERIES C SHARES, OR
SERIES D SHARES PURSUANT TO BOOK-ENTRY TRANSFER PROCEDURES.

    METHOD OF DELIVERY OF SHARES.  THE METHOD OF DELIVERY OF SHARES, THE LETTER
OF TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH THE
BOOK-ENTRY TRANSFER FACILITY, IS AT THE ELECTION AND RISK OF THE TENDERING
SHAREHOLDER. SHARES WILL BE DEEMED DELIVERED ONLY WHEN ACTUALLY RECEIVED BY THE
DEPOSITARY. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT
REQUESTED, PROPERLY INSURED, IS RECOMMENDED. IN ALL CASES, SUFFICIENT TIME
SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.

    SIGNATURE GUARANTEES.  No signature guarantee is required on the Letter of
Transmittal if (1) the Letter of Transmittal is signed by the registered holder
(which term, for purposes of this Section, includes any participant in the
Book-Entry Transfer Facility's system whose name appears on a security position
listing as the owner of the Shares) of Shares tendered therewith unless such
registered holder has completed either the box entitled "Special Payment
Instructions" or the box entitled "Special Delivery Instructions" on the Letter
of Transmittal or (2) such Shares are tendered for the account of a financial
institution (including most commercial banks, savings and loan associations and
brokerage houses) that is a participant in the Security Transfer Agents
Medallion Program, the New York Stock Exchange Medallion Signature Guarantee
Program or the Stock Exchange Medallion Program (each of the foregoing being
referred to as an "Eligible Institution"). In all other cases, all signatures on
the Letters of Transmittal must be guaranteed by an Eligible Institution. See
Instructions 1 and 5 to the Letter of Transmittal. If the

                                       5
<PAGE>
certificates for Shares are registered in the name of a person other than the
signer of the Letter of Transmittal, or if payment is to be made, or
certificates for Shares not tendered or not accepted for payment are to be
issued, to a person other than the registered holder of the certificates
surrendered, the tendered certificates must be endorsed or accompanied by
appropriate stock powers, in either case, signed exactly as the name or names of
the registered holders or owners appear on the certificates, with the signatures
on the certificates or stock powers guaranteed as aforesaid. See Instruction 5
to the Letter of Transmittal.

    GUARANTEED DELIVERY.  If a shareholder desires to tender Shares pursuant to
the Offer and such shareholder's certificates for Shares are not immediately
available or the procedures for book-entry transfer cannot be completed on a
timely basis or time will not permit all required documents to reach the
Depositary prior to the Expiration Date, such shareholder's tender may be
effected if all the following conditions are met:

    (1) such tender is made by or through an Eligible Institution;

    (2) a properly completed and duly executed Notice of Guaranteed Delivery
substantially in the form provided by the Purchaser is received by the
Depositary, as provided below, prior to the Expiration Date; and

    (3) the certificates for all tendered Shares, in proper form for transfer
(or a Book-Entry Confirmation with respect to such Shares), together with a
properly completed and duly executed Letter of Transmittal (or facsimile
thereof), with any required signature guarantees, or, in the case of a
book-entry transfer, an Agent's Message, and any other documents required by the
Letter of Transmittal, are received by the Depositary within three trading days
after the date of execution of such Notice of Guaranteed Delivery. A "trading
day" is any day on which the New York Stock Exchange, Inc. (the "NYSE") is open
for business.

    The Notice of Guaranteed Delivery may be delivered by hand to the Depositary
or transmitted by facsimile transmission or mail to the Depositary and must
include a guarantee by an Eligible Institution in the form set forth in such
Notice of Guaranteed Delivery.

    Notwithstanding any other provision hereof, payment for Shares accepted for
payment pursuant to the Offer will in all cases be made only after timely
receipt by the Depositary of (1) certificates for (or a timely Book-Entry
Confirmation with respect to) such Shares, (2) a Letter of Transmittal (or
facsimile thereof), properly completed and duly executed, with any required
signature guarantees, or, in the case of a book-entry transfer, an Agent's
Message, and (3) any other documents required by the Letter of Transmittal.
Accordingly, tendering shareholders may be paid at different times depending
upon when certificates for Shares or Book-Entry Confirmations are actually
received by the Depositary. UNDER NO CIRCUMSTANCES WILL INTEREST BE PAID ON THE
PURCHASE PRICE OF THE SHARES TO BE PAID BY THE PURCHASER, REGARDLESS OF ANY
EXTENSION OF THE OFFER OR ANY DELAY IN MAKING SUCH PAYMENT.

    The valid tender of Shares pursuant to one of the procedures described above
will constitute a binding agreement between the tendering shareholder and the
Purchaser upon the terms and subject to the conditions of the Offer.

    APPOINTMENT.  By executing a Letter of Transmittal, the tendering
shareholder will irrevocably appoint designees of the Purchaser as such
shareholder's attorneys-in-fact and proxies in the manner set forth in the
Letter of Transmittal, each with full power of substitution, to the full extent
of such shareholder's rights with respect to the Shares tendered by such
shareholder and accepted for payment by the Purchaser and with respect to any
and all other Shares or other securities or rights issued or issuable in respect
of such Shares on or after February 23, 2000. All such proxies shall be
considered coupled with an interest in the tendered Shares. Such appointment
will be effective when, and only to the extent that, the Purchaser accepts for
payment Shares tendered by such shareholder as provided herein. Upon such
acceptance for payment, all prior powers of attorney, proxies and consents given
by such shareholder with respect to such Shares or other securities or rights
will, without further action, be revoked and no subsequent powers of attorney,
proxies or consents may be given (and, if given, will not be deemed effective).
The designees of the Purchaser will thereby be empowered to exercise all voting
rights with

                                       6
<PAGE>
respect to such Shares or other securities or rights in respect of any annual,
special or adjourned meeting of the Company's shareholders, or otherwise, and
may execute any written consent, and may otherwise act as an attorney-in-fact
and proxy concerning any matter as they in their sole discretion deem proper.
The Purchaser reserves the right to require that, in order for Shares to be
deemed validly tendered, immediately upon the Purchaser's acceptance for payment
of such Shares, the Purchaser must be able to exercise full voting rights with
respect to such Shares and other securities or rights, including voting at any
meeting of shareholders then scheduled.

    DETERMINATION OF VALIDITY.  All questions as to the validity, form,
eligibility (including time of receipt) and acceptance of any tender of Shares
will be determined by the Purchaser, in its sole discretion, which determination
will be final and binding. The Purchaser reserves the absolute right to reject
any or all tenders determined by it not to be in proper form or the acceptance
for payment of, or payment for, any Shares which acceptance or payment, in the
opinion of the Purchaser's counsel, may be unlawful. The Purchaser also reserves
the absolute right to waive any defect or irregularity in any tender with
respect to any particular Shares, whether or not similar defects or
irregularities are waived in the case of other Shares. No tender of Shares will
be deemed to have been validly made until all defects or irregularities relating
thereto have been cured or waived. None of the Purchaser, Parent, the
Depositary, the Information Agent or any other person will be under any duty to
give notification of any defects or irregularities in tenders or will incur any
liability for failure to give any such notification. The Purchaser's
interpretation of the terms and conditions of the Offer (including the Letter of
Transmittal and the instructions thereto) will be final and binding.

    BACKUP FEDERAL INCOME TAX WITHHOLDING.  In order to avoid "backup
withholding" of federal income tax on payments of cash pursuant to the Offer, a
shareholder surrendering Shares in the Offer must, unless an exemption applies,
provide the Depositary with such Shareholder's correct Taxpayer Identification
Number ("TIN") on a Substitute Form W-9 and certify under penalty of perjury
that such TIN is correct and that such shareholder is not subject to backup
withholding. If a shareholder does not provide its correct TIN or fails to
provide the certifications described above, the Internal Revenue Service ("IRS")
may impose a penalty on such shareholder and payment of cash to such shareholder
pursuant to the Offer may be subject to backup withholding of 31%. All
shareholders surrendering Shares pursuant to the Offer should complete and sign
the main signature form and the Substitute Form W-9 included as part of the
Letter of Transmittal to provide the information and certification necessary to
avoid backup withholding (unless an applicable exemption exists and is proven in
a manner satisfactory to the Purchaser and the Depositary). Foreign shareholders
should complete and sign the main signature form of the Letter of Transmittal
and a Form W-8, Certificate of Foreign Status, a copy of which may be obtained
from the Depositary, in order to avoid backup withholding. See instruction 9 to
the Letter of Transmittal and "Important Tax Information" in the Letter of
Transmittal.

3.  WITHDRAWAL RIGHTS

    Except as otherwise provided in this Section 3, tenders of Shares are
irrevocable. Shares tendered pursuant to the Offer may be withdrawn pursuant to
the procedures set forth below at any time prior to the Expiration Date and,
unless theretofore accepted for payment and paid for by the Purchaser pursuant
to the Offer, may also be withdrawn at any time after May 14, 2000.

    For a withdrawal to be effective, a written or facsimile transmission notice
of withdrawal must be timely received by the Depositary at one of its addresses
set forth on the back cover of this Offer to Purchase and must specify the name
of the person having tendered the Shares to be withdrawn, the number and type of
Shares to be withdrawn and the name of the registered holder of the Shares to be
withdrawn, if different from the name of the person who tendered the Shares. If
certificates for Shares have been delivered or otherwise identified to the
Depositary, then, prior to the physical release of such certificates, the serial
numbers shown on such certificates must be submitted to the Depositary and,
unless such Shares have been tendered by an Eligible Institution, the signatures
on the notice of withdrawal must be guaranteed by an Eligible Institution. If
Common Shares have been tendered pursuant to the procedures for book-entry
transfer set forth in Section 2, any notice of withdrawal must also specify the

                                       7
<PAGE>
name and number of the account at the Book Entry Transfer Facility to be
credited with the withdrawn Common Shares and must otherwise comply with the
Book Entry Transfer Facility's procedures. Withdrawals of tenders of Shares may
not be rescinded, and any Shares properly withdrawn will thereafter be deemed
not validly tendered for any purposes of the Offer. However, withdrawn Shares
may be retendered by again following one of the procedures described in
Section 2 at any time prior to the Expiration Date.

    All questions as to the form and validity (including time of receipt) of
notices of withdrawal will be determined by the Purchaser, in its sole
discretion, which determination will be final and binding. None of the
Purchaser, Parent, the Depositary, the Information Agent or any other person
will be under any duty to give notification of any defects or irregularities in
any notice of withdrawal or incur any liability for failure to give any such
notification.

    If the Purchaser elects to provide a Subsequent Offering Period of three
business days to 20 business days after the Expiration Date pursuant to
Rule 14d-11 of the Exchange Act, no withdrawal rights shall apply during such
period in accordance with Rule 14d-7(a)(2) under the Exchange Act.

4.  ACCEPTANCE FOR PAYMENT AND PAYMENT FOR SHARES

    Upon the terms and subject to the conditions of the Offer (including, if the
Offer is extended or amended, the terms and conditions of any such extension or
amendment), the Purchaser will accept for payment and, promptly after the
Expiration Date, will pay for all Shares validly tendered prior to the
Expiration Date and not properly withdrawn in accordance with Section 3. Upon
the terms and subject to the conditions of the Offer, if the Purchaser elects to
provide a Subsequent Offering Period, the Purchaser will immediately accept and
promptly pay for all Shares as they are validly tendered during such Subsequent
Offering Period. Any determination concerning the satisfaction of such terms and
conditions will be within the sole discretion of the Purchaser, and such
determination will be final and binding on all tendering shareholders. See
Sections 1 and 14. The Purchaser expressly reserves the right, in its sole
discretion, to delay acceptance for payment of or payment for Shares in order to
comply with any applicable law. Any such delays will be effected in compliance
with Rule 14e-l(c) under the Exchange Act (relating to the Purchaser's
obligation to pay for or return tendered Shares promptly after the termination
or withdrawal of the Offer).

    In all cases, payment for Shares accepted for payment pursuant to the Offer
will be made only after timely receipt by the Depositary of (1) certificates for
such Shares (or timely Book-Entry Confirmation of a transfer of Common Shares as
described in Section 2), (2) a Letter of Transmittal (or facsimile thereof),
properly completed and duly executed, with any required signature guarantees and
(3) any other documents required by the Letter of Transmittal. The per Share
consideration paid to any holder of a particular class of securities of the
Company pursuant to the Offer will be the highest per Share consideration paid
for that same class of securities to any other holder of that same class of
securities pursuant to the Offer.

    For purposes of the Offer, the Purchaser will be deemed to have accepted for
payment, and thereby purchased, Shares properly tendered to the Purchaser and
not withdrawn, if and when the Purchaser gives oral or written notice to the
Depositary of the Purchaser's acceptance for payment of such Shares. Payment for
Shares accepted for payment pursuant to the Offer will be made by deposit of the
purchase price therefor with the Depositary, which will act as agent for
tendering shareholders for the purpose of receiving payment from the Purchaser
and transmitting payment to tendering shareholders. UNDER NO CIRCUMSTANCES WILL
INTEREST BE PAID ON THE PURCHASE PRICE OF THE SHARES TO BE PAID BY THE
PURCHASER, REGARDLESS OF ANY EXTENSION OF THE OFFER OR ANY DELAY IN MAKING SUCH
PAYMENT.

    If the Purchaser is delayed in its acceptance for payment of or payment for
Shares or is unable to accept for payment or pay for Shares pursuant to the
Offer for any reason, then, without prejudice to the Purchaser's rights under
the Offer (but subject to compliance with Rule 14e-l(c) under the Exchange Act,
which requires that a tender offeror pay the consideration offered or return the
tendered securities promptly after the termination or withdrawal of a tender
offer), the Depositary may, nevertheless, on

                                       8
<PAGE>
behalf of the Purchaser, retain tendered Shares. Any such Shares may not be
withdrawn except to the extent tendering shareholders are entitled to exercise,
and duly exercise, withdrawal rights as described in Section 3.

    If any tendered Shares are not purchased pursuant to the Offer because of an
invalid tender or otherwise, certificates for any such Shares will be returned,
without expense to the tendering shareholder (or, in the case of Common Shares
delivered by book-entry transfer of such Common Shares into the Depositary's
account at the Book-Entry Transfer Facility pursuant to the procedure set forth
in Section 2, such Common Shares will be credited to an account maintained at
the Book-Entry Transfer Facility), as promptly as practicable after the
expiration or termination of the Offer.

    The Purchaser reserves the right to transfer or assign, in whole or from
time to time in part, to Parent, or to one or more direct or indirect wholly
owned subsidiaries of Parent, the right to purchase Shares tendered pursuant to
the Offer. Any such transfer or assignment will not relieve the Purchaser of its
obligations under the Offer and will in no way prejudice the rights of tendering
shareholders to receive payment for Shares validly tendered and accepted for
payment pursuant to the Offer.

5.  CERTAIN FEDERAL INCOME TAX CONSEQUENCES

    The receipt of cash pursuant to the Offer will constitute a taxable
transaction for federal income tax purposes under the Internal Revenue Code of
1986, as amended (the "Code"), and may also constitute a taxable transaction
under applicable state, local, foreign and other tax laws. As a result, a
tendering shareholder will generally recognize gain or loss for Federal income
tax purposes in an amount equal to the difference between the amount of cash
received by the shareholder pursuant to the Offer and such shareholder's
aggregate adjusted tax basis in the Shares tendered and purchased pursuant to
the Offer. Gain or loss will be calculated separately for each block of Shares
tendered and purchased pursuant to the Offer. If tendered Shares are held by a
tendering shareholder as capital assets, any gain or loss recognized by the
tendering shareholder will constitute capital gain or loss, and will constitute
long-term capital gain or loss if the tendering shareholder held the underlying
Shares for more than 12 months as of the date of disposition. There are limits
on the deductibility of capital losses.

    A shareholder (other than certain exempt shareholders including, among
others, some corporations and certain foreign individuals) that tenders Shares
may be subject to backup withholding at a rate of 31% unless the shareholder
provides its correct TIN (or certifies that it is awaiting a TIN) and certifies
as to no loss of exemption from backup withholding and otherwise complies with
the applicable requirements of the backup withholding rules. A shareholder that
does not furnish its correct TIN in the prescribed manner or that does not
otherwise establish a basis for an exemption from backup withholding may be
subject to a penalty imposed by the IRS, and the gross proceeds of the Offer
payable to such shareholder may be subject to backup withholding at a rate of
31%. Each shareholder should complete and sign the Substitute Form W-9 included
as part of the Letter of Transmittal so as to provide the information and
certification necessary to avoid backup withholding.

    If backup withholding applies to a shareholder, the Depositary is required
to withhold 31% from payments to such shareholder. Backup withholding is not an
additional tax. Rather, the amount of the backup withholding can be credited
against the Federal income tax liability of the person subject to the backup
withholding, provided that the required information is given to the IRS. If
backup withholding results in an overpayment of tax, a refund can be obtained by
the shareholder upon filing an income tax return.

    THE FOREGOING DISCUSSION MAY NOT BE APPLICABLE WITH RESPECT TO SHARES
RECEIVED PURSUANT TO THE EXERCISE OF EMPLOYEE STOCK OPTIONS OR OTHERWISE AS
COMPENSATION OR WITH RESPECT TO HOLDERS OF SHARES WHO ARE SUBJECT TO SPECIAL TAX
TREATMENT UNDER THE CODE, SUCH AS NON-U.S. PERSONS, LIFE INSURANCE COMPANIES,
TAX-EXEMPT ORGANIZATIONS AND FINANCIAL INSTITUTIONS, AND MAY NOT APPLY TO A
HOLDER OF SHARES IN LIGHT OF SUCH PERSON'S INDIVIDUAL CIRCUMSTANCES.
SHAREHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS TO DETERMINE THE
PARTICULAR TAX CONSEQUENCES TO THEM (INCLUDING THE APPLICATION AND EFFECT OF ANY
STATE, LOCAL OR FOREIGN INCOME AND OTHER TAX LAWS) OF THE OFFER.

    On February 22, 2000, the last full day of trading before the public
announcement of the execution of the Merger Agreement, the reported last sale
price of the Common Shares on The Nasdaq SmallCap Stock Market(SM) was $3.6875
per Common Share. On March 14, 2000, the reported last sale price of the Common
Shares on The Nasdaq SmallCap Stock Market(SM) was $4.50 per Common Share.
Shareholders are urged to obtain current market quotations for the Common
Shares.

    According to the Company's Annual Report on Form 10-KSB, as amended, for the
fiscal year ended December 31, 1999 (the "Form 10-KSB"), the Company has not
paid cash dividends on its Common Shares or the Series A Shares since inception,
but the Company has paid the holders of the Series B Shares the current dividend
of $0.22 per share per annum (8% of the purchase price per share) plus its
dividends in arrears commencing in September 1994. Cash dividends paid on the
Series B Shares were $140,208 in 1999. The Company has paid holders of the
Series C Shares its current dividend of $0.165 per share per annum (6% of the
purchase price per share) plus its dividends in arrears commencing August 1995.
Cash dividends paid on the Series C Shares were $67,800 in 1999. Holders of the
Series D Shares are entitled to dividends of $0.2875 per share per annum (10% of
the purchase price per share) plus its dividend in arrears commencing
September 1995. Cash dividends paid on the Series D Shares were $135,556 in
1999. According to the Form 10-KSB, the Company is prohibited from paying
dividends on its Common Shares without the consent of the holders of (1) a
majority of the Series A Shares, Series B Shares, Series C Shares and Series D
Shares and (2) the Company's convertible promissory notes and the warrants
issued in connection therewith.

7.  EFFECT OF THE OFFER ON THE MARKET FOR THE COMMON SHARES; STOCK QUOTATION;
    EXCHANGE ACT REGISTRATION; MARGIN REGULATIONS

    The purchase of Common Shares pursuant to the Offer will reduce the number
of holders of Common Shares and the number of Common Shares that might otherwise
trade publicly and could adversely affect the liquidity and market value of the
remaining Common Shares held by the public.

    MARKET FOR SHARES.  Depending upon the number of Common Shares purchased
pursuant to the Offer, the Common Shares may no longer meet the requirements of
the National Association of Securities Dealers, Inc. (the "NASD") for continued
inclusion in The Nasdaq SmallCap Stock Market(SM). According to published
guidelines for the Nasdaq SmallCap Stock Market(SM), the Common Shares might no
longer be eligible for quotation on the Nasdaq SmallCap Stock Market(SM) if,
among other things, either (1) the

                                       10

Company's net tangible assets were less than $2,000,000, the Company's market
capitalization was less than $35,000,000, and the Company's net income (in
latest fiscal year or 2 of last 3 fiscal years) was less than $500,000, or
(2) the number of Common Shares publicly held was fewer than 500,000, there were
fewer than 300 holders of round lots, the aggregate market value of publicly
held Common Shares was less than $1,000,000, or there were fewer than two
registered and active market makers for the Common Shares. If these standards
are not met, the Common Shares might nevertheless continue to be included in The
Nasdaq Stock Market with quotations published in the Nasdaq "additional list" or
in one of the "local lists," but if the number of holders of the Common Shares
were to fall below 300, or if the number of publicly held Common Shares were to
fall below 100,000 or there were not at least two registered and active market
makers for the Common Shares, the NASD's rules provide that the Common Shares
would no longer be "qualified" for Nasdaq Stock Market reporting and The Nasdaq
Stock Market would cease to provide any quotations. Common Shares held directly
or indirectly by directors, officers or beneficial owners of more than 10% of
the Common Shares are not considered as being publicly held for this purpose.
According to the Company, as of December 31, 1999, there were approximately 283
holders of record of Common Shares, with approximately 2,600 beneficial holders
and 7,669,127 Common Shares outstanding. If, as a result of the purchase of
Common Shares pursuant to the Offer, the Common Shares no longer meet the
requirements of the NASD for continued inclusion in The Nasdaq Stock Market or
The Nasdaq SmallCap Stock Market(SM), as the case may be, the market for Common
Shares could be adversely affected.

    If the Common Shares no longer meet the requirements of the NASD for
quotation through any tier of The Nasdaq Stock Market, it is possible that the
Common Shares would continue to trade in the over-the-counter market and that
price quotations would be reported by other sources. The extent of the public
market for the Common Shares and the availability of such quotations would
depend, however, upon the number of holders of Common Shares remaining at such
time, the interest in maintaining a market in Common Shares on the part of
securities firms, the possible termination of registration of the Common Shares
under the Exchange Act, as described below, and other factors.

    There is no trading market for any of the Series A Shares, Series B Shares,
Series C Shares or Series D Shares. As of December 31, 1999, there were
approximately 3 holders of record of the Series A Shares, 27 holders of record
of the Series B Shares, 14 holders of record of the Series C Shares and 31
holders of record of the Series D Shares.

    EXCHANGE ACT REGISTRATION.  The Common Shares are currently registered under
the Exchange Act. Registration of the Common Shares under the Exchange Act may
be terminated upon application of the Company to the Commission if the Common
Shares are neither listed on a national securities exchange nor held by 300 or
more holders of record. Termination of registration of the Common Shares under
the Exchange Act would substantially reduce the information required to be
furnished by the Company to its shareholders and to the Commission and would
make certain provisions of the Exchange Act no longer applicable to the Company,
such as the shortswing profit recovery provisions of Section 16(b) of the
Exchange Act, the requirement of furnishing a proxy statement pursuant to
Section 14(a) of the Exchange Act in connection with shareholders' meetings and
the related requirement of furnishing an annual report to shareholders and the
requirements of Rule 13e-3 under the Exchange Act with respect to "going
private" transactions. Furthermore, the ability of "affiliates" of the Company
and persons holding "restricted securities" of the Company to dispose of such
securities pursuant to Rule 144 or 144A promulgated under the Securities Act of
1933, may be impaired or eliminated. The Purchaser intends to seek to cause the
Company to apply for termination of registration of the Common Shares under the
Exchange Act as soon after the completion of the Offer as the requirements for
such termination are met.

    If registration of the Common Shares is not terminated prior to the Merger,
then the Common Shares will cease to be reported on The Nasdaq Stock Market and
the registration of the Common Shares under the Exchange Act will be terminated
following the consummation of the Merger.

    MARGIN REGULATIONS.  The Common Shares are currently "margin securities"
under the regulations of the Board of Governors of the Federal Reserve System
(the "Federal Reserve Board"), which has the

                                       11
<PAGE>
effect, among other things, of allowing brokers to extend credit on the
collateral of the Common Shares. Depending upon factors similar to those
described above regarding listing and market quotations, it is possible that,
following the Offer, the Common Shares would no longer constitute "margin
securities" for the purposes of the margin regulations of the Federal Reserve
Board and therefore could no longer be used as collateral for loans made by
brokers. If registration of Common Shares under the Exchange Act were
terminated, the Common Shares would no longer be "margin securities."

    SUMMARY OF SIGNIFICANT DIFFERENCES BETWEEN UK GAAP FOLLOWED BY GYRUS GROUP
PLC AND US GAAP. The financial information set out above has been prepared under
UK GAAP which differs in certain significant respects from US GAAP. However,
there are no significant differences between UK GAAP and US GAAP which would
materially affect the net loss and shareholders' equity of Gyrus Group PLC ("the
Group") for each of the two years ended 30 June 1998 and 1999 and the unaudited
six month period to 31 December 1999.

    Consequently, the net loss and shareholders' equity for each period shown in
the financial information above would not be affected by the application of US
GAAP.

    The main differences resulting from the application of US GAAP would be the
reclassification of certain items within the balance sheet and cash flow
statements, as shown below.

    CURRENT LIABILITIES.  Deferred income (6 months ended 31 December 1999:
357,000 pounds sterling; year ended 30 June 1999: Nil pounds sterling and year
ended 30 June 1998: 749,000 pounds sterling), included for UK GAAP purposes as a
separate line after creditors falling due in more than one year,

                                       18
<PAGE>
represents amounts that the Group expects to be utilised within one year, which
would be reclassified to current liabilities under US GAAP.

    CONSOLIDATED STATEMENTS OF CASH FLOWS.  The consolidated statements of cash
flows prepared under UK GAAP in accordance with Financial Reporting Standard No
1 (Revised 1996), "Cash flow statements", present substantially the same
information as that required under US GAAP: Statement of Financial Accounting
Standard Number 95, "Statements of Cash Flows". These standards differ, however,
with regard to classification of items within the statements and as regards the
definition of the cash and cash equivalents.

    Under UK GAAP, cash does not include short term deposits and investments
which cannot be withdrawn without notice and without incurring a penalty. Such
items are shown as current asset investments. Under US GAAP deposits with a
maturity of less than three months at inception which are convertible into known
amounts of cash are included as cash and cash equivalents. Under UK GAAP, cash
flows are presented separately for operating activities, returns on investment
and servicing of finance, taxation, capital expenditure and financial
investment, acquisitions and disposals, management of liquid resources and
financing activities. US GAAP, however, requires only three categories of cash
flow activity to be reported; operating, investing and financing. Cash flows
from taxation and returns on investment and servicing of finance, shown under UK
GAAP, are included as operating activities under US GAAP.

    Summarised consolidated cash flow statements under US GAAP would be as
follows:

    OTHER DIFFERENCES.  Other minor differences exist between UK GAAP and US
GAAP in respect of certain items reflected in the financial information. Such
differences are immaterial to the reconciliation of net losses and shareholders'
equity and have been excluded accordingly.

10. SOURCE AND AMOUNT OF FUNDS

    The total amount of funds required by the Purchaser to purchase all
outstanding Shares pursuant to the Offer and to pay fees and expenses related to
the Offer and the Merger is estimated to be approximately $51.65 million. The
Purchaser plans to obtain all funds needed for the Offer and the Merger through
a capital contribution which will be made directly or indirectly by Parent to
the Purchaser.

    Parent intends to provide to the Purchaser the funds required to consummate
the Offer and the Merger from the proceeds of a Placing and Open Offer (the
"Placing and Open Offer") of 12,907,447 new ordinary 1p shares of Parent (the
"New Ordinary Shares") at 350 pence each, to raise approximately 45 million
pounds sterling (US $71 million). The New Ordinary Shares will be listed on the
London Stock Exchange, and will be issued to certain institutional investors and
to Parent's existing shareholders. The Placing and Open Offer is being fully
underwritten by Nomura International plc ("Nomura").

    The Placing and Open Offer is conditional, inter alia, on the following:

    (1) the prospectus (the "UK Prospectus") relating to the Placing and Open
       Offer being approved by the London Stock Exchange and filed with the
       Registrar of Companies in England and Wales by 4:00 p.m., London time, on
       April 17, 2000 (the "Launch Date");

                                       19
<PAGE>
    (2) the UK Prospectus, and associated documentation, being posted to
       Parent's shareholders by 12:00 midnight, London time, on the Launch Date;

    (3) satisfaction of all of the conditions to the Offer (Section 12);

    (4) the approval and adoption of the Merger Agreement, the Merger and the
       Placing and Open Offer by the requisite vote of the shareholders of
       Parent by not later than April 6, 2000 at a duly convened extraordinary
       general meeting ("EGM") of Parent (this EGM has been convened for
       April 6, 2000);

    (5) Nomura not having terminated the Placing Agreement (the "Placing
       Agreement") between itself and Parent in accordance with its terms prior
       to admission of the New Ordinary Shares to the London Stock Exchange's
       Official List ("Admission"). Nomura's rights to terminate the Placing
       Agreement include the right to terminate in the event of any material
       breach of the Placing Agreement (or the warranties and indemnities
       contained in it) occurring before Admission becomes effective; and

    (6) admission of the New Ordinary Shares becoming effective by not later
       than April 17, 2000 (or such later time as Parent and Nomura may agree).

    The conditions to the Placing and Open Offer described in sub-paragraphs (1)
and (2) listed above have been satisfied as of the date of the Offer. Parent and
Purchaser have not established any alternative financing arrangements or plans
in the event that the Placing and Open Offer is not successfully completed.

11. CONTACTS WITH THE COMPANY; BACKGROUND OF THE OFFER

    MERGER NEGOTIATIONS WITH THE COMPANY.  In July 1998, an investment banking
firm contacted the Company on behalf of Parent to discuss the Company's interest
in pursuing potential synergies with Parent. On November 3, 1998,
representatives of Parent met with representatives of the Company in Minneapolis
to discuss a potential relationship.

    In late November 1998, the Board of Directors of the Company directed
management of the Company to convey to Parent that the Company was not for sale
at that time. The Company's Board of Directors did not believe the Company's
current stock price was reflective of the Company's intrinsic value. Unless a
potential acquiror was in agreement with this assumption, the Company's Board of
Directors did not want to deter management's focus from executing its strategic
plan or incur the additional expense associated with the process of commencing
acquisition discussions, however preliminary. In late November 1998, this
statement was communicated to Parent. On December 11, 1998, Mark Goble, Chief
Executive Officer of Parent, authored a letter indicating continued interest in
discussions with the Company in the future.

    In July 1999, Mr. Goble contacted the Company to determine if it had
interest in further discussions with Parent. On September 10, 1999, Mark Goble,
Brian Steer, Chairman, and Colin Goble, Chief Technical Officer of Parent,
visited the Company to tour its facility and make general corporate
presentations. Specifically, Mr. Steer discussed Parent's interest in having a
distribution partner in the United States. Mr. Steer indicated that Parent, due
to the strategic fit between the two companies, continued to be interested in
acquiring the Company. John L. Shannon, Chief Executive Officer of the Company
reiterated the position taken by the Board of Directors of the Company in late
November 1998 with respect to an acquisition of the Company.

    On October 6, 1999, Mr. Steer telephoned Mr. Shannon to discuss an
acquisition of the Company by Parent, and proposed to hold a meeting
telephonically on October 21, 1999 to present an oral proposal to the Company
for consideration. On October 21, 1999, representatives of Parent, including
Nomura, had a telephone conference call with representatives of the Company,
including its corporate counsel, to discuss the structure and valuation range of
a potential acquisition of the Company by Parent.

    After subsequent telephone conversations between the two companies, on
November 9, 1999, Parent forwarded a letter to the Company setting forth its
non-binding indication of interest regarding the

                                       20
<PAGE>
possible acquisition of the Company's outstanding common stock, preferred stock,
options and warrants at a price range from $3 1/8 to $3 1/4, or approximately
$32 million, in cash, with standard conditions.

    In response to Parent's November 9, 1999 letter and upon direction from the
Company's Board of Directors, Mr. Shannon informed Mr. Steer that the Company's
Board of Directors did not believe the stock price at that time ($2.00 per
share) was indicative of its value and that the Company was willing to wait for
its stock price to increase or alternatively for someone to recognize the true
value of the Company, which the Board of Directors deemed to be at least
$50 million. Mr. Steer requested that Mr. Shannon provide a written reply to his
letter of November 9, 1999. Mr. Shannon complied with this request and sent a
letter to Mr. Steer on November 24, 1999 expressing the position of the Board of
Directors.

    On December 1, 1999, Nomura International plc, on behalf of Parent,
contacted the Company to continue the discussions. Mr. Shannon reiterated the
position of the Board of Directors regarding the valuation of the Company.
Following various conversations, Parent agreed to seriously consider the
valuation established by the Board of Directors and agreed to meet at Parent's
headquarters on January 7, 2000. Prior to this meeting, a confidentiality and
non-disclosure agreement was executed between the two parties. Various
representatives of Parent, including Nomura, and of the Company, participated in
this meeting.

    On January 19, 2000, Parent provided the Company with a confirmation of
interest letter proposing to proceed with an acquisition of all outstanding
common stock, preferred stock, options and warrants of the Company for $4.85 per
share in cash in a transaction to be structured as a merger. This confirmation
of interest letter was subject to a variety of conditions, including
satisfactory completion of Parent's due diligence investigation of the Company.

    After discussions with a Special Committee of the Company comprised of
independent directors and formed to evaluate the potential merger, Mr. Shannon
signed the confirmation of interest letter on January 24, 2000. Parent conducted
its due diligence review of the Company during the week of February 6, 2000.

    On February 11, 2000, counsel for Parent delivered to the Company and its
legal representatives drafts of the definitive transaction documentation,
including a proposed merger agreement.

    During the week of February 13, 2000, the Company and its legal
representatives and Parent and its legal representatives, continued to negotiate
the terms of the proposed merger agreement.

    On February 22, 2000, Dougherty & Company LLC, financial advisor to the
Company, rendered to the Board of Directors of the Company and its Special
Committee an opinion that the proposed transaction was fair to and in the best
interest of the Company and its shareholders, from a financial point of view.
Based upon discussions, presentations and this opinion, the Board of Directors
of the Company has unanimously approved the Merger and determined that the terms
of the Merger are fair to, and in the best interests of, the shareholders of the
Company and unanimously recommends that shareholders of the Company accept the
Offer and tender their Shares to the Purchaser pursuant to the terms of the
Offer.

    The merger agreement was signed and made effective as of February 23, 2000,
and a press release announcing the signing was issued in the morning of
February 23, 2000.

    CONSULTING AGREEMENT WITH THE COMPANY.  Parent and the Company executed a
Consulting Agreement, dated as of February 23, 2000 (the "Consulting
Agreement"), whereby Parent has retained the Company to provide to Parent
consulting and advisory services upon Parent's reasonable request from time to
time during the Consultancy Period (as defined below) in connection with
Parent's development of an independent sales network for the distribution of its
products in North America. The Consulting Agreement provides that the Company's
consultancy would commence on May 23, 2000 (the "Commencement Date") and is to
continue, unless the Consulting Agreement is terminated earlier in accordance
with its terms, through the fourth anniversary of the Commencement Date (the
"Consultancy Period"). The purpose of the Consulting Agreement is to provide for
an on-going relationship between the Company and Parent in the event that the
Merger Agreement is terminated under certain circumstances.

                                       21
<PAGE>
    The Consulting Agreement provides that in consideration of the Company's
performance of services during the Consultancy Period, Parent is to pay to the
Company a fee (the "Consultancy Fee") in the amount of one million dollars
($1,000,000.00), payable in four equal installments of $250,000 each, the first
such installment to be payable on the Commencement Date and each of the
remaining installments to be payable on each of the three subsequent anniversary
dates of the Commencement Date thereafter.

    Parent may terminate the Consulting Agreement prior to the completion of the
Consultancy Period if the Merger Agreement is terminated, in which case, no
Consultancy Fee would be payable to the Company. However, if Parent terminates
the Consulting Agreement because the Merger Agreement has been terminated
because the Placing and Open Offer is not completed or because the shareholders
of Parent do not approve the Placing and Open Offer, the entire Consultancy Fee
is payable by Parent to the Company.

12. PURPOSE OF THE OFFER; THE MERGER AGREEMENT

    PURPOSE OF THE OFFER.  The purpose of the Offer is to enable Parent to
acquire control of, and all of the equity interests in, the Company. Following
the consummation of the Offer, the Purchaser and Parent intend to acquire any
remaining equity interests in the Company not acquired in the Offer by
consummating the Merger. The Offer is subject to certain terms and conditions.
Notwithstanding anything to the contrary set forth in this Offer to Purchase,
any determination concerning the satisfaction of such terms and conditions will
be within the reasonable discretion of the Purchaser.

    THE MERGER AGREEMENT.  The Merger Agreement provides that following the
satisfaction or waiver of the conditions described below under "Conditions to
the Merger," the Company will be merged with and into the Purchaser, and each
then outstanding Share (other than Shares (1) owned by the Purchaser or Parent,
(2) remaining outstanding held by any subsidiary of Parent or (3) owned by
shareholders, if any, who are entitled to and who properly exercise dissenters'
rights under Minnesota law), will be converted into the right to receive an
amount in cash, without interest, equal to (a) in the case of the Common Shares,
the Common Share Offer Price, (b) in the case of the Series A Shares, the
Series A Offer Price, (c) in the case of the Series B Shares, the Series B Offer
Price, (d) in the case of the Series C Shares, the Series C Offer Price, and
(e) in the case of the Series D Shares, the Series D Offer Price, paid pursuant
to the Offer. Shares described in (1) and (2) of this paragraph will be
cancelled without the payment of any consideration.

    VOTE REQUIRED TO APPROVE THE MERGER.  The MBCA requires, among other things,
that the adoption of any plan of Merger or consolidation of the Company must be
approved by the Board of Directors of the Company and, if the "short form"
Merger procedure described below is not available, by the holders of a majority
of the Company's outstanding Shares, voting together as a single class. The
Board of Directors of the Company has approved the Offer, the Merger and the
Merger Agreement; consequently, the only additional corporate action of the
Company that may be necessary to effect the Merger is approval by the Company's
shareholders if the "short-form" Merger procedure described below is not
available. Under the MBCA, the affirmative vote of holders of a majority of the
outstanding Common Shares (including any Shares owned by the Purchaser), is
required to approve the Merger. In addition, holders of the Series A Shares,
Series B Shares, Series C Shares and Series D Shares will also have the right to
vote on the Merger, on the same basis as the holders of the Common Shares. If
the Purchaser acquires, through the Offer or otherwise, voting power with
respect to at least a majority of the outstanding Shares (which would be the
case if the Minimum Condition were satisfied and the Purchaser were to accept
for payment Shares tendered pursuant to the Offer), it would have sufficient
voting power to effect the Merger without the vote of any other shareholder of
the Company. The MBCA also provides, however, that if a parent company owns at
least 90% of each class of stock of a subsidiary, the parent company can effect
a "short-form" merger with that subsidiary without the action of the other
shareholders of the subsidiary. Accordingly, if, as a result of the Offer or
otherwise, the Purchaser acquires or controls the voting power of at least 90%
of the outstanding shares of each class (i.e., the Common Shares, Series A
Shares, Series B Shares, Series C Shares and Series D Shares), the Purchaser
could (and, under the Merger Agreement, is

                                       22
<PAGE>
required to) effect the Merger using the "short-form" merger procedures without
any action by any other shareholder of the Company.

    CONDITIONS TO THE MERGER.  The Merger Agreement provides that the respective
obligations of Parent, the Purchaser and the Company to effect the Merger are
subject to the fulfillment at or prior to the effective time of the Merger of
each of the following conditions: (1) other than as described above with respect
to the "short-form merger procedures" the Merger Agreement and the Merger shall
have been approved and adopted by the requisite vote of the shareholders of the
Company in accordance with the MBCA, (2) the Merger Agreement, the Merger and
the Placing and Open Offer shall have been approved and adopted by the requisite
vote of the shareholders of Parent in accordance with the Articles of
Association of Parent and the Companies Act of 1985 (as amended) and (3) no
temporary restraining order, preliminary or permanent injunction judgment or
other order, decree or ruling nor any statute, rule, regulation or order shall
be in effect which prevents the consummation of the Merger.

    The obligations of Parent and the Purchaser to effect the Merger are also
subject to the satisfaction at or prior to the closing date of the Merger of the
following conditions (unless any such condition is waived in writing by Parent
or the Purchaser):

Merger Agreement shall be true and correct in all material respects (without
giving duplicative effect to any materiality qualification contained in the
applicable representation or warranty) as of the closing date of the Merger with
the same force and effect as though made again at and as of the closing date of
the Merger, except for any representations and warranties that address matters
only as of a particular date (which shall remain true and correct in all
material respects (without giving duplicative effect to any materiality
qualification contained in the applicable representation or warranty) as of such
date) and Parent shall have received a certificate from the Company's chief
executive officer and chief financial officer to that effect;

    (2) the Company shall have performed in all material respects all
obligations required to be performed by the Company under the Merger Agreement
at or prior to the closing date of the Merger and Parent shall have received a

chief financial officer to that effect;

    (3) there shall not have occurred any change in the business, assets,
financial condition or results of operations of the Company which has had, or is
reasonably likely to have, individually or in the aggregate, a change or effect
that is materially adverse to the business, properties, assets, financial
condition, results of operations or condition of the Company taken as a whole or
the Company's ability to perform any of its obligations under the Merger
Agreement or which is expected to impede the Company's ability to consummate the
Merger (a "Material Adverse Effect");

    (4) the Company shall have received all necessary consents or waivers
relating to the Merger, in form and substance satisfactory to Parent, from the
other parties to each contract, lease or agreement to which the Company is a
party, except where the failure to obtain such consent or waiver would not
reasonably be expected, individually or in the aggregate, to have a Material
Adverse Effect;

    (5) the receipt by Parent of funds, or the unconditional right to draw funds
from the Placing and Open Offer;

    (6) the admittance of the New Ordinary Shares to the Official List of the
London Stock Exchange, subject to notice of admittance; and

    (7) the execution and delivery of the Employment Agreements (as defined in
the Merger Agreement) with Purchaser by certain Designated Company Employees (as
defined in the Merger Agreement).

    The obligations of the Company to effect the Merger are also subject to the
satisfaction at or prior to the closing date of the Merger of the following
conditions (unless any such condition is waived in writing by the Company):

    (1) the representations and warranties of Parent set forth in the Merger
Agreement shall be true and correct in all material respects (without giving
duplicative effect to any materiality qualification contained

                                       23
<PAGE>
in the applicable representation or warranty) as of the closing date of the
Merger with the same force and effect as though made again at and as of the
closing date of the Merger, except for any representations and warranties that
address matters only as of a particular date (which shall remain true and
correct in all material respects (without giving duplicative effect to any
materiality qualification contained in the applicable representation or
warranty) as of such date) and the Company shall have received a certificate to
that effect signed by Parent's president and chief executive officer and chief
financial officer; and

    (2) Parent shall have performed in all material respects all obligations
required to be performed by it under the Merger Agreement at or prior to the
closing date of the Merger and the Company shall have received a certificate to
that effect signed by Parent's president and chief executive officer and chief
financial officer.

    TERMINATION OF THE MERGER AGREEMENT.  The Merger Agreement may be terminated
at any time prior to the effective time of the Merger, whether before or after
approval of the Merger Agreement by the shareholders of the Company:

    (1) by mutual written agreement of the boards of directors of Parent and the
Company;

    (2) by Parent or the Company if (a) any court of competent jurisdiction in
the United States or other United States governmental body shall have issued an
order, decree or ruling or taken any other action restraining, enjoining or
otherwise prohibiting the Merger and such order, decree or ruling or other
action has become final and nonappealable, (b) there has been a material breach
by the other party of any representation, warranty, covenant or agreement set
forth in the Merger Agreement unless such breach is capable of being cured and
is cured prior to the closing date of the Merger, (c) the shareholders of Parent

shareholders of the Company shall fail to approve the Merger Agreement and the
Merger;

in this Section 12, (b) have approved or recommended an acquisition proposal by
a third party (other than Parent) or withdrawn or modified in a manner adverse
to Parent its approval or recommendation of the Merger Agreement and the
transactions contemplated thereby, or (c) have failed to mail a proxy statement
to the shareholders in connection with the approval of the Merger by the
shareholders of the Company or failed to include in such proxy statement its
recommendation of the Merger Agreement and the transactions contemplated
thereby, or publicly resolved to do any of the foregoing;

    (4) by Parent, if the Placing and Open Offer or the Placing Agreement shall
have been terminated without Parent having received the proceeds of the Placing
and Open Offer or any alternative financing;

    (5) by the Company, if in response to an acquisition proposal which
constitutes a Superior Proposal (as defined in "No Solicitation by the Company;
Acquisition Proposals" in this Section 12 below) which was not solicited by the
Company and which did not otherwise result from a breach of the covenants of the
Company described under "No Solicitation by the Company; Acquisition Proposals"
in this Section 12, if, in effecting such termination, the Company complies with
the relevant provisions of the Merger Agreement; or

    (6) by either Parent or the Company, in the event the effective time of the
Merger has not occurred by the latest to occur of (a) July 31, 2000 or
(b) 60 days after the clearance by the Commission of the proxy statement issued
in connection with approval of the Merger by the shareholders of the Company
(such date may thereafter be extended by mutual written agreement of Parent and
the Company),

    NO SOLICITATION BY THE COMPANY,- ACQUISITION PROPOSALS.  The Merger
Agreement provides that the Company shall not, nor will it authorize or permit
any of its, directors, officers or employees or any investment banker, financial
advisor, attorney, accountant or other representative retained by it to,
directly or indirectly, (1) solicit, initiate, entertain or encourage (including
by way of furnishing non-public information), any inquiries or the making of any
proposal which constitutes an Acquisition Proposal (as defined below) or
(2) participate in any discussions or negotiations regarding any Acquisition
Proposal.

                                       24

Notwithstanding the foregoing, if the Board of Directors of the Company
determines in good faith, after consultation with and receipt of advice from
outside counsel, that it is necessary to do so in order to comply with its
fiduciary duties to the Company's shareholders under applicable law, the
Company, in response to a Superior Proposal (as defined below) which was not
solicited by it or which did not result from a breach by the Company of its
non-solicitation obligations, and subject to compliance with the Merger
Agreement, may furnish information with respect to the Company to any person
making a Superior Proposal pursuant to a confidentiality agreement entered into
between such person and the Company on terms no less favorable than the
confidentiality agreement between the Company and Parent and participate in
discussions or negotiations regarding such Superior Proposal.

    For purposes of the Merger Agreement, an "Acquisition Proposal" means any
inquiry, proposal or offer from any person (1) relating to any direct or
indirect acquisition or purchase of (a) a business that constitutes 15% or more
of the net revenues, net income or the assets of the Company, taken as a whole,
or (b) 20% or more of any class of equity securities of the Company,
(2) relating to any tender offer or exchange offer that if consummated would
result in any person beneficially owning 20% or more of any class of equity
securities of the Company, or (3) relating to any merger, consolidation,
business combination, recapitalization, liquidation, dissolution or similar
transaction involving the Company, other than the transactions contemplated by
the Merger Agreement.

    For purposes of the Merger Agreement, "Superior Proposal" means any proposal
made by a third party to acquire, directly or indirectly, including pursuant to
a tender offer, exchange offer, merger, consolidation, business combination,
recapitalization, liquidation, dissolution or similar transaction, for
consideration consisting of cash and/or securities, more than 50% of the
combined voting power of the Shares then outstanding or all or substantially all
the assets of the Company and otherwise on terms which the Board of Directors of
the Company determines in its good faith judgment is reasonably likely to be
consummated, taking into account the person making the proposal and all legal,
financial and regulatory aspects of the proposal, and would provide greater
value to the shareholders of the Company than the Merger.

    The Merger Agreement provides further that neither the Board of Directors of
the Company nor any committee thereof may (1) withdraw or modify, or propose
publicly to withdraw or modify, or propose publicly to withdraw or modify, in a
manner adverse to Parent, the approval or recommendation by the Board of
Directors or such committee of the Offer, the Merger or the Merger Agreement,
(2) approve or recommend, or propose publicly to approve or recommend, any
Acquisition Proposal or (3) cause the Company to enter into any letter of
intent, agreement in principle, acquisition agreement or other similar agreement
related to any Acquisition Proposal, other than any such agreement entered into
concurrently with the termination of the Merger Agreement by the Company to
facilitate such action. See "Termination of the Merger Agreement" in this
Section 12.

    The Merger Agreement provides that the Company must promptly advise Parent
orally and in writing of any request for non-public information, any Acquisition
Proposal, including all of the material proposed terms of such Acquisition
Proposal, the identity of the third party, or any decision by the company to
furnish information with respect to the Company to any person making such
request for non-public information or Acquisition Proposal pursuant to a
confidentiality agreement (as described in the Merger Agreement) or to
participate in discussions or negotiations with any person regarding an
Acquisition Proposal. The Company must promptly deliver such notice to Parent
(and in no event later than 24 hours) after the Company's receipt of any request
for non-public information or of any Acquisition Proposal and prior to the
Company taking any of the actions described above. The Company must also keep
Parent reasonably informed of the status of any such request or Acquisition
Proposal and will update the information required by the Merger Agreement to be
provided to Parent upon the request of Parent.

    FEES AND EXPENSES; TERMINATION FEE.  The Merger Agreement generally provides
that all fees and expenses incurred in connection with the Offer, the Merger,
the Merger Agreement and the transactions contemplated by the Merger Agreement
will be paid by the party incurring such fees or expenses, whether or not the
Offer or the Merger is consummated.

                                       25
<PAGE>
    The Merger Agreement also provides that the Company shall pay 7.0% of the
total aggregate Merger Consideration to Parent as reimbursement of Parent's
expenses and as liquidated damages (the "Company Break-Up Fee"), within three
business days after termination of the Merger Agreement by Parent or the
Company, as applicable, in the event that:

    (1) there has been a material breach by the Company of any representation,
warranty, covenant or agreement set forth in the Merger Agreement unless such
breach is capable of being cured and is cured prior to the closing date of the
Merger;

    (2) the Company or any of its directors or officers shall participate, or
have publicly resolved to participate, in discussions or negotiations in breach
of the Company's covenants described under "No Solicitation by the Company;
Acquisition Proposals" in this Section 12;

    (3) the Board of Directors of the Company shall have approved or
recommended, or have publicly resolved to approve or recommend, an Acquisition
Proposal by a third party or withdrawn or modified in a manner adverse to Parent
its approval or recommendation of the Merger Agreement or the transactions
contemplated thereby;

    (4) the Company failed to, or have publicly resolved to not, mail the proxy
statement regarding the Merger to its shareholders or failed to include in such
proxy statement the recommendation of the Board of Directors that the
shareholders of the Company vote in favor of the Merger; or

    (5) the Company terminates the Merger Agreement in response to a Superior
Proposal which was not solicited by the Company and which does not otherwise
result from a breach of the non-solicitation or other covenants of the Company
described above under "No Solicitation by the Company; Acquisition Proposals" in
this Section 12.

    The Merger Agreement further provides that the Company shall pay the Company
Break-Up Fee to Parent if the Company consummates an "Acquisition Transaction"
within 12 months after Parent or the Company's termination of the Merger
Agreement due to the failure of the shareholders of the Company to approve the
Merger Agreement and the Merger at a meeting of the Company's shareholders. In
such case, the Company Break-Up Fee is payable within three business days after
the consummation of such "Acquisition Transaction."

    CONDUCT OF THE BUSINESS OF THE COMPANY.  The Merger Agreement provides that
except as required or permitted by the Merger Agreement or as disclosed in the
Company's disclosure schedule attached to the Merger Agreement, the Company
shall not, from the date of the Merger Agreement until the effective time of the
Merger, without the prior written consent of Parent (which consent will be given
or denied within a reasonable time after any request for such consent):

    (1) amend its articles of organization or other charter document or by-laws;

    (2) authorize for issuance, issue, sell, deliver, pledge or agree or commit
to issue, sell, deliver or pledge (whether through the issuance or granting of
options, warrants, commitments, subscriptions, rights to purchase or otherwise)

capital stock or equivalents (including, without limitation, stock appreciation
rights), or amend any of the terms of any of the foregoing, other than the
issuance of shares of capital stock upon the exercise of outstanding options or
rights in accordance with the terms of the Company's Incentive Stock Option
Plan, Nonqualified Stock Option Plan and Stock Bonus Plan (collectively, the
"Company Equity Plans");

    (3) (a) split, combine or reclassify any shares of its capital stock, or
authorize or propose the issuance or authorization of any other securities in

stock or property or any combination thereof) in respect of its capital stock,
adopt or approve any shareholder rights plan or agreement providing for the
issuance to holders of Shares of rights to purchase or receive stock, cash or
other assets upon the acquisition or proposed acquisition of Shares, or
repurchase, redeem or otherwise acquire any of its securities, or (b) make any
payment of cash or other property to terminate, cancel or otherwise settle any
outstanding options, other than in the case of clauses (a) or (b) above for the
issuance of Common Shares in connection with the exercise of options or rights
under the Company Equity Plans;

acceleration of vesting of outstanding options under the Company Equity Plans
and termination of the Company's Employee Stock Purchase Plan, enter into, adopt
or amend in any manner or terminate any bonus, profit sharing, compensation,
severance, termination, stock option, stock appreciation right, restricted
stock, performance unit, stock equivalent, stock purchase agreement, pension,
retirement, deferred compensation, employment, severance, change-in-control or
other employee benefit agreement, trust, plan, fund or other arrangement for the

that the Company may waive, release or amend its rights under any such

failure to do so would be reasonably likely to constitute a breach of its
fiduciary duties to the Company's shareholders under applicable law;

    (15) make or change any election, request permission of any tax authority or

applicable to any federal, state, local, foreign or other tax claim or
assessment relating to the Company;

    (16) settle or comprise any pending or threatened suit, action or claim
which is material or which relates to any of the transactions contemplated by
the Merger Agreement;

    (17) take any action that would reasonably be expected to result in (a) any
of the representations and warranties of the Company set forth in the Merger
Agreement becoming untrue or (b) any of the conditions of the Offer not being
satisfied; or

    (18) take, or agree in writing or otherwise to take, any of the actions
described in sub-paragraphs (1) through (17) listed above.

    BOARD OF DIRECTORS.  The Merger Agreement provides that promptly upon the
acceptance for payment of, and payment for, Shares by the Purchaser pursuant to
the Offer, the Purchaser shall be entitled to designate such number of directors
on the Board of Directors of the Company as will give the Purchaser, subject to
compliance with Section 14(f) of the Exchange Act, representation on the
Company's Board of Directors equal to the product of (1) the total number of
directors on the Company's Board of Directors and (2) the percentage that the
number of Shares purchased by the Purchaser in the Offer bears to the number of
Shares outstanding, and the Company shall, at such time, cause the Purchaser's
designees to be selected by its existing Board of Directors. Subject to
applicable law, the Company has agreed to take all action requested by Parent
necessary to effect any such election, including mailing to its shareholders the
Information Statement containing the information required by Section 14(f) of
the Exchange Act and Rule 14f-1 promulgated thereunder. The Merger Agreement
further provides that in the event that the Purchaser's designees are elected to
the Board of Directors of the Company, until the effective time of the Merger,
the Board of Directors of the Company will have at least two independent
directors who were directors on the date of the Merger Agreement and who are not
officers of the Company. The Merger Agreement also provides that the Company
will promptly, at the option of Parent, either increase the size of the
Company's Board of Directors and/or obtain the resignation of such number of its
current directors as is necessary to enable the Purchaser's designees to be
elected or appointed to, and to constitute a majority of, the Company's Board of
Directors as provided above.

    STOCK OPTIONS.  The Merger Agreement provides that prior to the effective
time of the Merger, the Company shall terminate the Company Equity Plans and
shall provide written notice to each holder of a then outstanding stock option
or other right to purchase Common Shares pursuant to the Company Equity Plans
(whether or not such option is then vested or exercisable), that such option
shall be exercisable in full as of the date of such notice and that such option
shall terminate at the effective time of the Merger and that, if such option is
not exercised or otherwise terminated before the effective time of the Merger,
such holder shall be entitled to receive in cancellation of such option a cash
payment from Parent promptly after

                                       28
<PAGE>
the effective time of the Merger, in an amount equal to the excess, if any, by
which the Common Share Offer Price exceeds the exercise price per share with
respect to such option, if any, multiplied by the number of shares represented
by such option immediately prior to such cancellation, subject to income tax
withholding as required by applicable law.

    WARRANTS.  The Merger Agreement also provides that, prior to the effective
time of the Merger, the Company shall take all actions necessary to procure, on
or before the Expiration Date, from each holder of an outstanding warrant to
purchase Common Shares an agreement that, as of the effective time of the
Merger, such warrant shall be converted into a right of such holder to receive
from Parent promptly after the effective time of the Merger an amount in cash,
without interest equal to the product of (1) the number of Common Shares subject
to such warrant immediately prior to the effective time of the Merger and
(2) the excess, if any, by which the Common Share Offer Price exceeds the
exercise price per share that was applicable with respect to such warrant.

    EMPLOYEE MATTERS.  The Merger Agreement provides that from and after the
effective time of the Merger, Parent will cause the Surviving Corporation to
provide to employees of the Company who remain employed after the effective time
of the Merger ("Company Employees") with the types and levels of employee
benefits which are in the aggregate at least as favorable as those maintained by
the Company prior to the effective time, provided that this obligation shall not
include the Company's employee stock purchase plan or the Company Equity Plans.
The Merger Agreement further provides that Parent will treat, and cause its
applicable benefit plans to treat, the service of Company Employees with the
Company as service rendered to the Surviving Corporation for purposes of
eligibility to participate, vesting and for other appropriate benefits but not
for benefit accrual.

    In addition, the Merger Agreement also provides that the Company shall use
its reasonable best efforts to cause certain of its employees to enter into
employment agreements with the Surviving Corporation on the terms and conditions
set forth in attached exhibits to the Merger Agreement. In particular, it is
expected that each of Steven M. Blakemore, the Company's Vice President,
Operations and Engineering, Michael E. Geraghty, the Company's Vice President,
Sales and Marketing, Thomas F. Murphy, the Company's Vice President, Finance and
Administration and Assistant Secretary and David J. Parins, the Company's Vice
President, Technology, will enter into employment agreements with the Surviving
Corporation providing for their employment following the completion of the
Merger. None of Messrs. Blakemore, Geraghty, Murphy or Parins is party to an
employment agreement with the Company prior to the Merger. Under the terms of
these employment agreements, each of which is substantially identical, each
officer will be employed by the Surviving Corporation in their current
positions. Each agreement has a term of three years and provides for salary and
benefits substantially equivalent to that which each officer is paid prior to
the Merger.

    INDEMNIFICATION.  The Merger Agreement provides that from and after the
effective time of the Merger and for a period of six years thereafter, the
Surviving Corporation (1) will maintain all rights to indemnification (including
with respect to the advancement of expenses incurred in the defense of any
action or suit) existing on the date of the Merger Agreement in favor of the
present and former directors, officers, employees and agents of the Company as
provided in the Company's Articles of Incorporation and By-Laws, in each case as
in effect on the date of this Agreement, and that during such period, neither
the Articles of Incorporation nor the By-Laws of the Surviving Corporation shall
be amended to reduce or limit the rights of the indemnity afforded to the
present and former directors, officers, employees and agents of the Company, or
the ability of the Surviving Corporation to indemnify them, nor to hinder, delay
or make more difficult the exercise of such rights or the ability to indemnify
and (2) agrees to indemnify to the fullest extent permitted under its
Certificate of Incorporation, its By-Laws, and applicable law the present and
former directors, officers, employees and agents of the Company against all
losses, damages, liabilities or claims made against them arising from their
service in such capacities prior to and including the effective time of the
Merger, to at least the same extent as such persons are currently permitted to
be indemnified pursuant to the Company's Articles of Incorporation and By-Laws.
Furthermore, the Merger Agreement provides that Parent will cause to be
maintained for a period of four years from the effective

                                       29
<PAGE>
time of the Merger the Company's current directors' and officers' insurance and
the indemnification policy to the extent that it provides coverage for events
occurring prior to the effective time of the Merger for all persons who were
directors and officers of the Company on February 23, 2000, so long as such
insurance is available on commercially reasonable terms and the annual premium
for such liability insurance would not be in excess of 200% of the last annual
premium paid prior to the date of the Merger Agreement. If the existing
officers' and directors' liability insurance expires, is terminated or cancelled
during such four-year period, Parent will use all reasonable efforts to cause to
be obtained as much officers' and directors' liability insurance as can be
obtained for the remainder of such period for an annualized premium as provided
in the Merger Agreement and on terms and conditions no less advantageous than
the existing officers' and directors' liability insurance.

    COMMERCIALLY REASONABLE EFFORTS.  Upon the terms and subject to the
conditions set forth in the Merger Agreement and Parent and the Company's
respective board of directors' fiduciary duties to their respective shareholders
under applicable law, each of Parent, the Purchaser and the Company have agreed
to take, or cause to be taken, all actions, and to do, or cause to be done, and
to cooperate with each other in doing, all things necessary, proper or advisable
to consummate and make effective, as promptly as practicable, the Offer, the
Merger and the other transactions contemplated by the Merger Agreement,
including the use of their respective commercially reasonable efforts to
(1) obtain all necessary waivers, consents and approvals from other parties to
loan agreements, leases, licenses and other contracts, (2) obtain all necessary
consents, approvals and authorizations as required to be obtained under any
federal, state or foreign law or regulation, (3) defend all lawsuits or other
legal proceedings challenging the Merger Agreement or the consummation of the
transactions contemplated by the Merger Agreement, (4) lift or rescind any
injunction or restraining order or other order adversely affecting the ability
of the parties to consummate the transactions contemplated by the Merger
Agreement, (5) effect all necessary registrations and filings, including, but
not limited to, submissions of information requested by any foreign, federal,
state or local government, court, administrative agency or commission or other
governmental authority or instrumentality, domestic or foreign, and (6) fulfill
all conditions to this agreement. In connection with and without limiting the
foregoing, but subject to the terms and conditions of the Merger Agreement, the
Company and its Board of Directors will (1) take all action necessary to ensure
that no state takeover statute or similar statute or regulation is or becomes
applicable to the Offer, the Merger, the Merger Agreement or any of the other
transactions contemplated by the Merger Agreement, and (2) if any state takeover
statute or similar statute or regulation becomes applicable to the Offer, the
Merger, the Merger Agreement or any other transaction contemplated by the Merger
Agreement, take all action necessary to ensure that the Offer, the Merger, the
Merger Agreement and the other transactions contemplated by the Merger Agreement
may be consummated as promptly as practicable on the terms contemplated by the
Offer and the Merger Agreement and otherwise to minimize the effect of such
statute or regulation on the Offer, the Merger, the Merger Agreement and the
other transactions contemplated by the Merger Agreement.

    The Merger Agreement further provides that the Company will give prompt
notice to Parent, and Parent will give prompt notice to the Company, of (1) the
occurrence, or non-occurrence, of any event which would be likely to cause any
representation or warranty contained in the Merger Agreement to be untrue or
inaccurate in any material respect at any time from the date of the Merger
Agreement through the effective time of the Merger and (2) any material failure
of the Company or Parent to comply with or satisfy any covenant, condition or
agreement to be complied with or satisfied by it under the Merger Agreement;
provided that no such notification will limit or otherwise affect the remedies
available to the party receiving the notice.

    REPRESENTATIONS AND WARRANTIES.  The Merger Agreement contains various
customary representations and warranties. The foregoing summary of the Merger
Agreement is qualified in its entirety by reference to the Merger Agreement, a
copy of which is filed as Exhibit 9 to the Purchaser's Tender Offer Statement on
Schedule TO filed with the Commission on the date hereof (the "Schedule TO") and
incorporated by reference herein. The Merger Agreement should be read in its
entirety for a more complete description of the matters summarized above.

                                       30
<PAGE>
    APPRAISAL RIGHTS.  No appraisal rights are available in connection with the
Offer. However, if the Merger is consummated holders of Shares will have certain
rights pursuant to the provisions of Sections 302A.471 and 302A.473 of the MBCA
to dissent and demand appraisal of, and to receive payment in cash of the fair
value of, their Shares. If the statutory procedures are complied with, such
rights could lead to a judicial determination of the fair value required to be
paid in cash to such dissenting holders for their Shares. In determining the
fair value of the Shares, the court is required to take into account all
relevant factors. Accordingly, any such judicial determination of the fair value
of Shares could be based upon considerations other than or in addition to the
Common Share Offer Price, the Series A Offer Price, the Series B Offer Price,
the Series C Offer Price or the Series D Offer Price or the market value of the
Shares, including the asset value and investment value of the Shares. The value
so determined could be more or less than the Offer Price or the Merger
Consideration.

    If any holder of Shares who demands appraisal under Section 302A.471 and
302A.473 of the MBCA fails to perfect, or effectively withdraws or loses his
right to appraisal, as provided in the MBCA, the Shares of such shareholder will
be converted into the Merger Consideration in accordance with the Merger
Agreement.

    The foregoing discussion is not a complete statement of law pertaining to
appraisal rights under the MBCA and is qualified in its entirety by the full
text of Section 302A.471 and 302A.473 of the MBCA.

    FAILURE TO FOLLOW THE STEPS REQUIRED BY THE MBCA FOR PERFECTING APPRAISAL
RIGHTS MAY RESULT IN THE LOSS OF SUCH RIGHTS.

    GOING PRIVATE TRANSACTIONS.  The Merger will have to comply with any
applicable Federal law operative at the time of its consummation. Rule 13e-3
under the Exchange Act is applicable to certain "going private" transactions.
The Purchaser does not believe that Rule 13e-3 will be applicable to the Merger
unless the Merger is consummated more than one year after the termination of the
Offer. If applicable, Rule 13e-3 would require, among other things, that certain
financial information concerning the Company and certain information relating to
the fairness of the Merger and the consideration offered to minority
shareholders be filed with the Commission and disclosed to minority shareholders
prior to consummation of the Merger.

13. DIVIDENDS AND DISTRIBUTIONS

    Pursuant to the terms of the Merger Agreement, prior to the effective time
of the merger, unless approved in writing by the Purchaser, the Company may not
(1) declare, set aside, make or pay any dividends on, or make any other
distributions in respect of, any of its capital stock, or (b) issue or sell any
shares of any class of its capital stock, or any securities convertible into or
exchangeable for any such shares, or issue, sell, grant or enter into any
subscriptions, options, warrants, conversion or other rights, agreements,
commitments, arrangements or understandings of any kind, contingently or
otherwise to purchase or otherwise acquire any such shares or securities
convertible into or exchangeable for any such shares. Nothing herein shall
constitute a waiver by the Purchaser or Parent of any of its rights under the
Merger Agreement or a limitation of remedies available to the Purchaser or
Parent for any breach of the Merger Agreement, including termination thereof.

14. CERTAIN CONDITIONS OF THE OFFER

    Notwithstanding any other term of the Offer or the Merger Agreement, the
Purchaser will not be required to accept for payment or, subject to any
applicable rules and regulations of the Commission, including Rule 14e-l(c)
under the Exchange Act (relating to the Purchaser's obligation to pay for or
return tendered Shares after the termination or withdrawal of the Offer), to pay
for any Shares tendered pursuant to the Offer unless the Minimum Condition shall
have been satisfied. Furthermore, the Purchaser will not be required to accept
for payment or, as described above, to pay for any Shares not previously
accepted for

                                       31
<PAGE>
payment or paid for, if, upon the scheduled expiration date of the Offer (as
extended, if required, pursuant to the provisions discussed in Section 1 above),
any of the following conditions exists and is continuing:

    (1) there shall be instituted or pending by any governmental entity any
suit, action or proceeding (a) challenging the acquisition by Parent or the
Purchaser of any Shares under the Offer, seeking to restrain or prohibit the
making or consummation of the Offer or the Merger or the performance of any of
the other transactions contemplated by the Merger Agreement or seeking to obtain
from the Company, Parent or the Purchaser any damages that are material in
relation to the Company, (b) seeking to prohibit or materially limit the
ownership or operation by the Company, Parent or any of Parent's subsidiaries of
all or a portion of the business or assets of the Company or Parent and its
subsidiaries, taken as a whole, or to compel the Company or Parent and its
subsidiaries to dispose of or hold separate all or a portion of the business or
assets of the Company or Parent and its subsidiaries, taken as a whole, in each
case as a direct result of the Offer or any of the other transactions
contemplated by the Merger Agreement, (c) seeking to impose material limitations
on the ability of Parent or the Purchaser to acquire or hold, or exercise full
rights of ownership of, any Shares to be accepted for payment pursuant to the
Offer, including, without limitation, the right to vote such Shares on all
matters properly presented to the shareholders of the Company, (d) seeking to
prohibit Parent or any of its subsidiaries from effectively controlling in any
material respect any material portion of the business or operations of the
Company, (e) that could reasonably be expected to require the divestiture by

on the Company or Parent;

    (2) there shall be any statute, rule, regulation, judgment, order or

    (5) the Company shall have failed to perform in any material respect any
obligation or to comply in any material respect with any agreement or covenant

benefit of Parent and the Purchaser and may be waived by Parent and the
Purchaser in whole or in part at any time and from time to time in their sole
discretion. The failure by Parent or the Purchaser at any time to exercise any
of the foregoing rights will not be deemed a waiver of any such right, the
waiver of any such right with respect to particular facts and circumstances will
not be deemed a waiver with respect to any other facts and circumstances and
each such right will be deemed an ongoing right that may be asserted at any time
and from time to time.

15. CERTAIN LEGAL MATTERS

    Based on a review of publicly available filings made by the Company with the
Commission and other publicly available information concerning the Company and
representations made by representatives of the Company and the Company, neither
the Purchaser nor Parent is aware of any license or regulatory permit that
appears to be material to the business of the Company, that might be adversely
affected by the Purchaser's acquisition of Shares as contemplated herein or of
any approval or other action, except as otherwise described in this Section 15,
by any governmental entity that would be required for the acquisition or
ownership of Shares by the Purchaser as contemplated herein. Should any such
approval or other action be required, the Purchaser and Parent currently
contemplate that such approval or other action will be sought. Except as
otherwise expressly described in this Section 15, while the Purchaser does not
presently intend to delay the acceptance for payment of or payment for Shares
tendered pursuant to the Offer pending the outcome of any such matter, there can
be no assurance that any such approval or other action, if needed, would be
obtained or would be obtained without substantial conditions or that failure to
obtain any such approval or other action might not result in consequences
adverse to the Company's business or that certain parts of the Company's
business might not have to be disposed of if such approvals were not obtained or
such other actions were not taken or in order to obtain any such approval or
other action. If certain types of adverse action are taken with respect to the
matters discussed below, the Purchaser could decline to accept for payment or
pay for any Shares tendered. See Section 14 for certain conditions to the Offer.

    MINNESOTA FILING.  As the Offer involves a Minnesota company, many of whose
shareholders are Minnesota residents, the Offer may be subject to the provisions
of Chapter 80B of the Minnesota General Corporation Law, known as the Takeover
Disclosure Act. Under this Act, it is unlawful to make any takeover offer to
acquire any equity securities of a target company in Minnesota unless a
registration statement is filed with the Minnesota Commissioner of Commerce,
together with certain other documents. The information required to be included
in this registration statement is substantially identical to that contained in
the Schedule TO filed by the Purchaser with the Commission in connection with
the Offer. In addition, the Purchaser is required to file the Schedule TO and
exhibits, including this Offer to Purchase, with the registration statement.
This filing is required to be made simultaneously with the commencement of the
Offer. On March 16, 2000, simultaneously with the announcement of the Offer,
Purchaser made this filing. It is not expected that compliance with this Act
will delay the completion of the Offer.

    ANTITRUST.  Under the provisions of the Hart-Scott Rodino Antitrust
Improvements Act of 1976, as amended (the "HSR Act"), and the regulations
thereunder applicable to the Offer, an acquiring person and the person whose
voting securities are being acquired in a tender offer must make an HSR filing
by filing a Notification and Report Form with respect to the tender offer if
each of the following three

                                       33
<PAGE>
conditions are satisfied: (1) the acquiring person or the person whose voting
securities are being acquired are engaged in commerce or in any activity
affecting commerce, (2)(a) any voting securities or assets of a person engaged
in manufacturing which has annual net sales or total assets of $10,000,000 or
more are being acquired by any person which has total assets or annual net sales
of $100,000,000 or more, (b) any voting securities or assets of a person not
engaged in manufacturing which has total assets of $10,000,000 or more are being
acquired by any person which has total assets or annual net sales of
$100,000,000 or more or (c) any voting securities or assets of a person with
annual net sales or total assets of $100,000,000 or more are being acquired by
any person which has total assets or annual net sales of $10,000,000 or more,
and (3) as a result of such acquisition, the acquiring person would hold
(a) 15% or more of the voting securities or assets of the acquired person, or
(b) an aggregate total amount of the voting securities and assets of the
acquired person in excess of $15,000,000.

    Although Parent, the Purchaser and the Company are engaged in commerce in
satisfaction of the first statutory condition to an HSR filing stated above, and
the consummation of the Offer will result in the acquisition by the Purchaser of
15% or more of the voting securities or assets of the Company in satisfaction of
the third statutory condition to an HSR filing stated above, none of Parent, the
Purchaser and the Company have total assets or annual net sales of $100,000,000
or more in satisfaction of the second statutory condition to an HSR filing.
Therefore, none of Parent, the Purchaser, or the Company is required to file a
Notification and Report Form with respect to the Offer under the HSR Act and
applicable regulations.

    Nevertheless, the FTC and the Antitrust Division may scrutinize the legality
of transactions such as the Purchaser's proposed acquisition of the Company
under the antitrust laws. If the Antitrust Division or the FTC raises
substantive issues in connection with a proposed transaction, the parties may
engage in negotiations with the relevant governmental agency concerning possible
means of addressing those issues and may agree to delay consummation of the
transaction while such negotiations continue. At any time before or after the
Purchaser's purchase of Shares pursuant to the Offer, the Antitrust Division or
FFC could take such action under the antitrust laws as it deems necessary or
desirable in the public interest, including seeking to enjoin the purchase of
Shares pursuant to the Offer or the consummation of the Merger or seeking the
divestiture of Shares acquired by the Purchaser or the divestiture of
substantial assets of Parent or its subsidiaries, or the Company. Private
parties may also bring legal action under the antitrust laws under certain
circumstances. There can be no assurance that a challenge to the Offer on
antitrust grounds will not be made or, if such a challenge is made, of the
results thereof.

    OTHER FOREIGN APPROVALS.  The Company conducts business in a number of
foreign countries and jurisdictions. In connection with the acquisition of
Shares pursuant to the Offer, the laws of certain of those foreign countries and
jurisdictions may require the filing of information with, or the obtaining of
the approval of, governmental authorities in such countries and jurisdictions.
The governments in such countries and jurisdictions might attempt to impose
additional conditions on the Company's operations conducted in such countries
and jurisdictions as a result of the acquisition of the Shares pursuant to the
offer. There can be no assurance that the Purchaser will be able to cause the
Company to satisfy or comply with such laws or that compliance or non-compliance
will not have adverse consequences for the Company after purchase of the Shares
pursuant to the Offer.

16. FEES AND EXPENSES

    The Purchaser has retained MacKenzie Partners, Inc. to act as the
Information Agent and Wilmington Trust Company to serve as the Depositary in
connection with the Offer. The Information Agent and the Depositary each will
receive reasonable and customary compensation for their services, be reimbursed
for certain reasonable out-of-pocket expenses and be indemnified against certain
liabilities and expenses in connection therewith, including certain liabilities
under the Federal securities laws.

    Neither the Purchaser nor Parent will pay any fees or commissions to any
broker or dealer or other person (other than the Information Agent and the
Depositary) in connection with the solicitation of tenders of Shares pursuant to
the Offer. Brokers, dealers, banks and trust companies will be reimbursed by

                                       34
<PAGE>
the Purchaser upon request for customary mailing and handling expenses incurred
by them in forwarding materials to their customers.

17. MISCELLANEOUS

    The Offer is not being made to (nor will tenders be accepted from or on
behalf of) holders of Shares in any jurisdiction in which the making of the
Offer or the acceptance thereof would not be in compliance with the laws of such
jurisdiction. Neither the Purchaser nor Parent is aware of any jurisdiction in
which the making of the Offer or the tender of Shares in connection therewith
would not be in compliance with the laws of such jurisdiction. To the extent the
Purchaser or Parent becomes aware of any state law that would limit the class of
offerees in the Offer, the Purchaser will amend the Offer and, depending on the
timing of such amendment, if any, will extend the Offer to provide adequate
dissemination of such information to holders of Shares prior to the expiration
of the Offer.

    NO PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR TO MAKE ANY
REPRESENTATION ON BEHALF OF THE PURCHASER OR PARENT NOT CONTAINED HEREIN OR IN
THE LETTER OF TRANSMITTAL AND, IF GIVEN OR MADE, SUCH INFORMATION OR
REPRESENTATION MUST NOT BE RELIED UPON AS HAVING BEEN AUTHORIZED.

    The Purchaser or Parent has filed with the Commission a Schedule TO pursuant
to Rule 14d-3 under the Exchange Act, furnishing certain additional information
with respect to the Offer. In addition, the Company has filed with the
Commission a Schedule 14D-9 pursuant to Rule 14d-9 under the Exchange Act
setting forth its recommendation with respect to the Offer and the reasons for
such recommendation and furnishing certain additional related information. Such
Schedules and any amendments thereto, including exhibits, should be available
for inspection and copies should be obtainable in the manner set forth in
Section 8 (except that they will not be available at the regional offices of the
Commission).

England and Wales ("Parent"), the above-described shares of (1) Common Stock,

of Everest Medical Corporation, a Minnesota corporation (the "Company"), upon
the terms and subject to the conditions set forth in the Purchaser's Offer to

hereby acknowledged.

    Upon the terms of the Offer, subject to, and effective upon, acceptance for
payment of, and payment for, the Shares tendered herewith in accordance with the
terms of the Offer, the undersigned hereby sells, assigns and transfers to, or
upon the order of, the Purchaser all right, title and interest in and to all the
Shares that are being tendered hereby (and any and all other Shares or other
securities or rights issued or issuable in respect thereof on or after
February 23, 2000), and irrevocably constitutes and appoints Wilmington Trust
Company (the "Depositary"), the true and lawful agent and attorney-in-fact of
the undersigned, with full power of substitution (such power of attorney being
deemed to be an irrevocable power coupled with an interest), to the full extent
of the undersigned's rights with respect to such Shares (and any such other
Shares or securities or rights in the Company), (1) to deliver certificates for
such Shares (and any such other Shares or securities or rights) or,
alternatively, in the case of Common Shares, transfer ownership of such Common
Shares (and any such other Common Shares or securities or rights) on the account
books maintained by the Book-Entry Transfer Facility together, in any such case,
with all accompanying evidences of transfer and authenticity to, or upon the
order of, the Purchaser, (2) to present such Shares (and any such other Shares
or securities or rights) for transfer on the Company's books and (3) to receive
all benefits and otherwise exercise all rights of beneficial ownership of such
Shares (and any such other Shares or securities or rights), all in accordance

    The undersigned hereby represents and warrants that the undersigned has full
power and authority to tender, sell, assign and transfer the tendered Shares
(and any and all other shares or other securities or rights issued or issuable
in respect of such Shares on or after February 23, 2000) and, when the same are
accepted for payment by the Purchaser, the Purchaser will acquire good title
thereto, free and clear of all liens, restrictions, claims and encumbrances, and
the same will not be subject to any adverse claim. The undersigned, upon
request, will execute any additional documents deemed by the Depositary or the
Purchaser to be necessary or desirable to complete the sale, assignment and
transfer of the tendered Shares (and any and all such other Shares or securities
or rights).

    All authority conferred or agreed to be conferred pursuant to this Letter of
Transmittal shall be binding upon the successors, assigns, heirs, executors,
administrators and legal representatives of the undersigned and shall not be
affected by, and shall survive, the death or incapacity of the undersigned.
Except as stated in the Offer to Purchase, this tender is irrevocable.

    The undersigned hereby irrevocably appoints Mark Goble and John Bradshaw,
and each of them acting singly, and any other designees of the Purchaser, the
attorneys-in-fact and proxies of the undersigned, each with full power of
substitution, to vote at any annual, special or adjourned meeting of the
Company's shareholders or otherwise in such manner as each such attorney-in-fact
and proxy or his substitute shall in his or her sole discretion deem proper with
respect to, to execute any written consent concerning any matter as each such
attorney-in-fact and proxy or his or her substitute shall in his or her sole
discretion deem proper with respect to, and to otherwise act as each such
attorney-in-fact and proxy or his or her substitute shall in his or her sole
discretion deem proper with respect to, the Shares tendered hereby that have
been accepted for payment by the Purchaser prior to the time any such action is
taken and with respect to which the undersigned is entitled to vote (and any and
all other Shares or other securities or rights issued or issuable in respect of
such Shares on or after February 23, 2000). This appointment is effective when,

provided in the Offer to Purchase. This power of attorney and proxy are
irrevocable and are granted in consideration of the acceptance for payment of
such Shares in accordance with the terms of the Offer. Upon such acceptance for
payment, all prior powers of attorney, proxies and consents given by the
undersigned with respect to such Shares (and any such other Shares or securities
or rights) will, without further action, be revoked and no subsequent powers of
attorney, proxies, consents or revocations may be given (and, if given, will not
be deemed effective) by the undersigned.

    The undersigned understands that the valid tender of Shares pursuant to any
of the procedures described in Section 2 of the Offer to Purchase and in the
Instructions hereto will constitute a binding agreement between the undersigned
and the Purchaser upon the terms and subject to the conditions of the Offer.

                                  INSTRUCTIONS
             FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER

    1.  GUARANTEE OF SIGNATURES. No signature guarantee is required on this
Letter of Transmittal (1) if this Letter of Transmittal is signed by the
registered holder(s) (which term, for purposes of this Section, includes any
participant in the Book-Entry Transfer Facility's system whose name appears on a
security position listing as the owner of the Common Shares) of Shares tendered
herewith, unless such registered holder(s) has completed either the box entitled
"Special Payment Instructions" or the box entitled "Special Delivery
Instructions" on this Letter of Transmittal or (2) if such Shares are tendered
for the account of a financial institution (including most commercial banks,
savings and loan associations and brokerage houses) that is a participant in the
Security Transfer Agents Medallion Program, the New York Stock Exchange
Medallion Signature Guarantee Program or the Stock Exchange Medallion Program
(such participant, an "Eligible Institution"). In all other cases, all
signatures on this Letter of Transmittal must be guaranteed by an Eligible
Institution. See Instruction 5.

    2.  REQUIREMENTS OF TENDER. This Letter of Transmittal is to be completed by
shareholders either if certificates are to be forwarded herewith or, unless an
Agent's Message (as defined below) is utilized, if delivery of Common Shares is
to be made pursuant to the procedures for book-entry transfer set forth in
Section 2 of the Offer to Purchase

    For a shareholder to validly tender Common Shares pursuant to the Offer,
either (1) a Letter of Transmittal (or facsimile thereof), properly completed
and duly executed, together with any required signature guarantees, or, in the
case of a book-entry transfer, an Agent's Message, and any other required
documents, must be received by the Depositary at one of its addresses set forth
herein prior to the Expiration Date and either certificates for tendered Common
Shares must be received by the Depositary at one of such addresses or such
Common Shares must be delivered pursuant to the procedures for book-entry
transfer set forth herein (and a Book-Entry Confirmation received by the
Depositary), in each case prior to the Expiration Date, or (2) the tendering
shareholder must comply with the guaranteed delivery procedures set forth below
and in Section 2 of the Offer to Purchase.

    For a shareholder to validly tender Series A Shares, Series B Shares,
Series C Shares or Series D Shares pursuant to the Offer, either (1) a properly
completed and duly executed Letter of Transmittal (or facsimile thereof),
together with any required signature guarantees and any other documents required
by the Letter of Transmittal, and certificates for tendered Series A Shares,
Series B Shares, Series C Shares or Series D Shares, as the case may be, must be
received by the Depositary at one of its addresses set forth on the back cover
of this Offer to Purchase prior to the Expiration Date or (2) the tendering
shareholder must comply with the guaranteed delivery procedure set forth below.
A shareholder may not validly tender Series A Shares, Series B Shares, Series C
Shares, or Series D shares pursuant to book-entry transfer procedures.

    If a shareholder desires to tender Shares pursuant to the Offer and such
shareholder's certificates for Shares are not immediately available or the
procedures for book-entry transfer cannot be completed on a timely basis or time
will not permit all required documents to reach the Depositary prior to the
Expiration Date, such shareholder's tender may be effected by properly
completing and duly executing the Notice of Guaranteed Delivery pursuant to the
guaranteed delivery procedures set forth in Section 2 of the Offer to Purchase.
Pursuant to such procedures, (1) such tender must be made by or through an
Eligible Institution, (2) a properly completed and duly executed Notice of
Guaranteed Delivery, substantially in the form provided by the Purchaser, must
be received by the Depositary prior to the Expiration Date and (3) the
certificates for all tendered Shares in proper form for transfer (or, if
applicable in the case of Common Shares, a Book-Entry Confirmation with respect
to all such Common Shares), together with a Letter of Transmittal (or facsimile
thereof), properly completed and duly executed, with any required signature
guarantees, or, in the case of a book-entry transfer, an Agent's Message, and
any other required documents, must be received by the Depositary within three
trading days after the date of execution of such Notice of Guaranteed Delivery
as provided in Section 2 of the Offer to Purchase. A "trading day" is any day on
which the New York Stock Exchange, Inc. is open for business.

    The term "Agent's Message" means a message transmitted by the Book-Entry
Transfer Facility to, and received by, the Depositary and forming a part of a
Book-Entry Confirmation, which states that the Book-Entry Transfer Facility has
received an express acknowledgment from the participant in the Book-Entry
Transfer Facility tendering the Common Shares that such participant has received
and agrees to be bound by the terms of the Letter of Transmittal and that the

    THE METHOD OF DELIVERY OF SHARES, THE LETTER OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS, INCLUDING DELIVERY OF COMMON SHARES THROUGH THE BOOK-ENTRY
TRANSFER FACILITY, IS AT THE ELECTION AND RISK OF THE TENDERING SHAREHOLDER.
SHARES WILL BE DEEMED DELIVERED ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY
(INCLUDING, IN THE CASE OF A BOOK-ENTRY TRANSFER OF COMMON SHARES, BY BOOK-ENTRY
CONFIRMATION). IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT
REQUESTED, PROPERLY INSURED, IS RECOMMENDED. IN ALL CASES, SUFFICIENT TIME
SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.

    No alternative, conditional or contingent tenders will be accepted and no
fractional Shares will be purchased. All tendering shareholders, by execution of
this Letter of Transmittal (or facsimile thereof), waive any right to receive
any notice of the acceptance of their Shares for payment.

    3.  INADEQUATE SPACE. If the space provided herein is inadequate, the
certificate numbers and/or the number of Shares should be listed on a separate
schedule attached hereto.

    4.  PARTIAL TENDERS. (Applicable to Certificate Shareholders Only). If fewer
than all the Shares evidenced by any certificate submitted are to be tendered,
fill in the number of Shares that are to be tendered in the box entitled "Number
of Shares Tendered." In any such case, new certificate(s) for the remainder of
the Shares that were evidenced by the old certificate(s) will be sent to the
registered holder, unless otherwise provided in the appropriate box on this
Letter of Transmittal, as soon as practicable after the acceptance for payment
of, and payment for, the Shares tendered herewith. All Shares represented by
certificates delivered to the Depositary will be deemed to have been tendered
unless otherwise indicated.

    5.  SIGNATURES ON LETTER OF TRANSMITTAL, STOCK POWERS AND ENDORSEMENTS.  If
this Letter of Transmittal is signed by the registered holder of the Shares
tendered hereby, the signature must correspond with the name as written on the
face of the certificate(s) without any change whatsoever.

    If any of the Shares tendered hereby are owned of record by two or more
joint owners, all such owners must sign this Letter of Transmittal.

    If any tendered Shares are registered in different names on several
certificates, it will be necessary to complete, sign and submit as many separate
Letters of Transmittal as there are different registrations of certificates.

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

    When this Letter of Transmittal is signed by the registered owner(s) of the
Shares listed and transmitted hereby, no endorsements of certificates or
separate stock powers are required unless payment is to be made to, or
certificates for Shares not tendered or accepted for payment are to be issued
to, a person other than the registered owner(s). Signatures on such certificates
or stock powers must be guaranteed by an Eligible Institution.

    If this Letter of Transmittal is signed by a person other than the
registered owner(s) of the certificates listed, the certificates must be
endorsed or accompanied by appropriate stock powers, in either case signed
exactly as the name or names of the registered owner or owners appear on the
certificates. Signatures on such certificates or stock powers must be guaranteed
by an Eligible Institution.

    6.  STOCK TRANSFER TAXES. The Purchaser will pay any stock transfer taxes
with respect to the transfer and sale of Shares to it or its order pursuant to
the Offer. If, however, payment of the purchase price is to be made to, or if
certificates for Shares not tendered or accepted for payment are to be
registered in the name of, any person(s) other than the registered owner(s), or
if tendered certificates are registered in the name(s) of any person(s) other
than the person(s) signing this Letter of Transmittal, the amount of any stock
transfer taxes (whether imposed on the registered owner(s) or such person(s))
payable on account of the transfer to such person(s) will be deducted from the
purchase price unless satisfactory evidence of the payment of such taxes or
exemption therefrom is submitted.

    EXCEPT AS PROVIDED IN THIS INSTRUCTION 6, IT WILL NOT BE NECESSARY FOR
TRANSFER TAX STAMPS TO BE AFFIXED TO THE CERTIFICATES LISTED IN THIS LETTER OF
TRANSMITTAL.

    7.  SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS. If a check is to be issued in
the name of, and/or certificates for Shares not accepted for payment are to be
returned to, a person other than the signer of this Letter of Transmittal or

                                       8
<PAGE>
if a check is to be sent and/or such certificates are to be returned to a person
other than the signer of this Letter of Transmittal or to an address other than
that shown above, the appropriate boxes on this Letter of Transmittal should be
completed.

    8.  WAIVER OF CONDITIONS. The Purchaser reserves the absolute right to waive
any of the specified conditions of the Offer, in whole or in part at any time
and from time to time in its sole discretion.

    9.  BACKUP WITHHOLDING; SUBSTITUTE FORM W-9. In order to avoid backup
withholding of Federal income tax on payments of cash pursuant to the Offer, a
stockholder surrendering Shares in the Offer must, unless an exemption applies,
provide the Depositary with such stockholder's correct taxpayer identification
number ("TIN") on Substitute Form W-9 below in this Letter of Transmittal and
certify under penalty of perjury that such TIN is correct and that such
stockholder is not subject to backup withholding. If a stockholder does not
provide such shareholder's correct TIN or fails to provide the certifications
described above, the Internal Revenue Service (the "IRS") may impose a penalty
on such stockholder and the payment of cash to such stockholder pursuant to the
Offer may be subject to backup withholding of 31%.

    Backup withholding is not an additional income tax. Rather, the amount of
the backup withholding can be credited against the U.S. federal income tax
liability of the person subject to the backup withholding, provided that the
required information is given to the IRS. If backup withholding results in an
overpayment of tax, a refund can be obtained by the stockholder upon filing an
income tax return.

    10. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES. Questions and requests for
assistance or additional copies of the Offer to Purchase, this Letter of
Transmittal, the Notice of Guaranteed Delivery and the Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9 may be
directed to the Information Agent at its address set forth below.

    11. LOST, DESTROYED OR STOLEN CERTIFICATES.  If any certificate representing
Shares has been lost, destroyed or stolen, the stockholder should promptly
notify the Depositary by checking the box immediately preceding the special
payment/special delivery instructions and indicating the number of Shares lost.
The stockholder will then be instructed as to the steps that must be taken in
order to replace the certificate. This Letter of Transmittal and related
documents cannot be processed until the procedures for replacing lost or
destroyed certificates have been followed.

    IMPORTANT: THIS LETTER OF TRANSMITTAL (OR FACSIMILE HEREOF), TOGETHER WITH
ANY REQUIRED SIGNATURE GUARANTEES, OR, IN THE CASE OF A BOOK-ENTRY TRANSFER, AN
AGENT'S MESSAGE, AND ANY OTHER REQUIRED DOCUMENTS, MUST BE RECEIVED BY THE
DEPOSITARY PRIOR TO THE EXPIRATION DATE AND EITHER CERTIFICATES FOR TENDERED
SHARES MUST BE RECEIVED BY THE DEPOSITARY OR SHARES MUST BE DELIVERED PURSUANT
TO THE PROCEDURES FOR BOOK-ENTRY TRANSFER, IN EACH CASE, PRIOR TO THE EXPIRATION
DATE, OR THE TENDERING SHAREHOLDER MUST COMPLY WITH THE PROCEDURES FOR
GUARANTEED DELIVERY.

                           IMPORTANT TAX INFORMATION

    Under Federal income tax law, a shareholder is required to provide the
Depositary such shareholder's TIN (i.e., social security number or employer
identification number) on Substitute Form W-9 (or otherwise establish a basis
for exemption from backup withholding) and certify under penalty of perjury that
such TIN is correct and that such shareholder is not subject to backup
withholding. If the Shares are held in more than one name or are not in the name
of the actual owner, consult the enclosed "Guidelines for Certification of
Taxpayer Identification Number on Substitute Form W-9" for additional guidance
on which number to report. If the Depositary is not provided with a
shareholder's correct TIN, the shareholder or other payee may be subject to a
penalty imposed by the Internal Revenue Service. In addition, any amounts
payable to such shareholder in connection with the Offer may be subject to
backup withholding at a 31% rate.

    The box in Part 3 of the Substitute Form W-9 may be checked if the tendering
shareholder has not been issued a TIN and has applied for a TIN or intends to
apply for a TIN in the near future. If the box in Part 3 is checked, the
shareholder or other payee must also complete the Certificate of Awaiting
Taxpayer Identification Number below in order to avoid backup withholding.
Notwithstanding that the box in Part 3 is checked and the Certificate of
Awaiting Taxpayer Identification Number is completed, the Depositary will
withhold 31% on all payments made prior to the time a properly certified TIN is
provided to the Depositary.

    Foreign shareholders should complete and sign the main signature form and a
Form W-8, Certificate of Foreign Status, a copy of which may be obtained from
the Depositary, in order to avoid backup withholding. See the enclosed
"Guidelines for Certification of Taxpayer Identification Number on Substitute
Form W-9" for more instructions.

         REQUEST FOR TAXPAYER                number (or I am waiting for a number to be issued to me) and
      IDENTIFICATION NUMBER (TIN)            (2) I am not subject to backup withholding because (a) I am exempt from
                                             backup withholding, or (b) I have not been notified by the Internal Revenue
                                                 Service ("IRS") that I am subject to backup withholding as a result of a
                                                 failure to report all interest or dividends, or (c) the IRS has notified
                                                 me that I am no longer subject to backup withholding.
                                             CERTIFICATION INSTRUCTIONS You must cross out item(s) in Part 2 above if you
                                             have been notified by the IRS that you are subject to backup withholding
                                             because you have failed to report all interest or dividends on your tax
                                             returns. However, if after being notified by the IRS that you were subject
                                             to backup withholding you received another notification from the IRS stating
                                             that you are no longer subject to backup withholding, do not cross out such
                                             item (2). If you are exempt from backup withholding, check the box in Part 4

withholding. For details, see the regulations under sections 6041, 6041A(a),
6045, and 6050A.

    PRIVACY ACT NOTICE.--Section 6109 requires most recipients of dividends,
interest, or other payments to give taxpayer identification numbers to payers
who must report the payments to IRS. IRS uses the numbers for identification
purposes. Payers must be given the numbers whether or not recipients are
required to file tax returns. Payers must generally withhold 31% of taxable
interest, dividends, and certain other payments to a payee who does not furnish
a taxpayer identification number to a payer. Certain penalties may also apply.

PENALTIES

(1) PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER.--If you fail
    to furnish your taxpayer identification number to a payer, you are subject
    to a penalty of $50 for each such failure unless your failure is due to
    reasonable cause and not to willful neglect.

(2) FAILURE TO REPORT CERTAIN DIVIDEND AND INTEREST PAYMENTS.--If you fail to
    include any portion of an includible payment for interest, dividends, or
    patronage dividends in gross income, such failure will be treated as being
    due to negligence and will be subject to a penalty of 20% on any portion of
    an underpayment attributable to that failure unless there is clear and
    convincing evidence to the contrary.

(3) CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING.--If you
    make a false statement with no reasonable basis which results in no
    imposition of backup withholding, you are subject to a penalty of $500.

(4) CRIMINAL PENALTY FOR FALSIFYING INFORMATION.--Falsifying certifications or
    affirmations may subject you to criminal penalties including fines and/or
    imprisonment.

                        FOR ADDITIONAL INFORMATION, CONTACT
                      YOUR TAX CONSULTANT OR THE INTERNAL

                                GYRUS GROUP PLC

    Golden Acquisition Corp., a Delaware corporation (the "Purchaser") and a
wholly-owned subsidiary of Gyrus Group PLC, a public limited company
incorporated and existing under the laws of England and Wales ("Parent"), is
offering to purchase all outstanding shares of (1) Common Stock, par value $.01

value $.01 per share (the "Series A Shares"), (3) Series B 8% Convertible
Preferred Shares, par value $.01 per share (the "Series B Shares"),
(4) Series C 6% Convertible Redeemable Preferred Stock, par value $.01 per share
(the "Series C Shares"), and (5) Series D 10% Convertible Redeemable Preferred
Stock, par value $.01 per share (the "Series D Shares" and, collectively with
the Series A Shares, the Series B Shares, the Series C Shares and the Common
Shares, the "Shares"), of Everest Medical Corporation, a Minnesota corporation
(the "Company"), at $4.85 per Share, net to the seller in cash, upon the terms
and subject to the conditions set forth in the Offer to Purchase for Cash, dated
March 16, 2000, and in the related Letter of Transmittal (which together with
any amendments or supplements thereto, collectively constitute the "Offer").

    THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 NOON, NEW YORK CITY
TIME, ON THURSDAY, APRIL 13, 2000, UNLESS EXTENDED.
<PAGE>
    The Offer is conditioned upon, among other things, there being validly
tendered and not withdrawn prior to the expiration of the Offer such number of
Shares that would constitute at least a majority of an aggregate of the
outstanding Shares (determined on a fully diluted basis for all outstanding
stock options and any other rights to acquire Shares on the date of purchase)
(the "Minimum Condition").

    The Offer is being made pursuant to an Agreement and Plan of Merger, dated
as of February 23, 2000 (the "Merger Agreement"), among Parent, the Purchaser
and the Company pursuant to which, following the consummation of the Offer, the
Company will be merged with and into the Purchaser (the "Merger"). On the
effective date of the Merger, each outstanding Share (other than Shares owned by
Parent, the Purchaser or any other subsidiary of Parent or by shareholders of
the Company, if any, who are entitled to and who properly exercise appraisal
rights under Minnesota law) will be converted into the right to receive $4.85,
in cash, without interest.

    THE BOARD OF DIRECTORS OF THE COMPANY, AFTER RECEIVING THE UNANIMOUS
RECOMMENDATION OF THE SPECIAL COMMITTEE OF THE BOARD OF DIRECTORS, HAS
UNANIMOUSLY APPROVED THE OFFER AND THE MERGER AND DETERMINED THAT THE TERMS OF
THE OFFER AND THE MERGER ARE FAIR TO, AND IN THE BEST INTERESTS OF, THE
SHAREHOLDERS OF THE COMPANY, AND UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS OF THE
COMPANY ACCEPT THE OFFER AND TENDER THEIR SHARES.

    For purposes of the Offer, the Purchaser shall be deemed to have accepted
for payment, and thereby purchased, Shares properly tendered to the Purchaser
and not properly withdrawn as, if and when the Purchaser gives oral or written
notice to the Depositary of the Purchaser's acceptance for payment of such
Shares. Upon the terms and subject to the conditions of the Offer, payment for
Shares purchased pursuant to the Offer will be made by deposit of the purchase
price therefor with the Depositary, which will act as agent for tendering
shareholders for the purpose of receiving payment from the Purchaser and
transmitting payment to tendering shareholders whose Shares have been accepted
for payment. In all cases, payment for Common Shares purchased pursuant to the
Offer will be made only after timely receipt by the Depositary of
(i) certificates for such Common Shares or timely confirmation of book-entry
transfer of such Common Shares into the Depositary's account at the Book-Entry
Transfer Facility (as defined in the Offer to Purchase) pursuant to the
procedures set forth in Section 2 of the Offer to Purchase, (ii) a properly
completed and duly executed Letter of Transmittal (or facsimile thereof) with
any required signature guarantees, or, in the case of a book-entry transfer of
Common Shares, an Agent's Message (as defined in the Offer to Purchase) and
(iii) any other documents required by the Letter of Transmittal. In all cases,
payment for Series A Shares, Series B Shares, Series C Shares or Series D Shares
purchased pursuant to the Offer will be made only after timely receipt by the
Depositary of (i) certificates for such Series A Shares, Series B Shares,
Series C Shares or Series D Shares pursuant to the procedures set forth in
Section 2 of the Offer to Purchase, (ii) a properly completed and duly executed
Letter of Transmittal (or facsimile thereof) with any required signature
guarantees and (iii) any other documents required by the Letter of Transmittal.
A shareholder may not validly tender Series A Shares, Series B Shares, Series C
Shares or Series D Shares using book-entry transfer procedures. Under no
circumstances will interest be paid by the Purchaser on the purchase price of
the Shares to be paid by the Purchaser, regardless of any extension of the Offer
or any delay in making such payment.

    The term "Expiration Date" means 12:00 noon, New York City time, on
April 13, 2000, unless and until the Purchaser, in its sole discretion, but
subject to the terms of the Merger Agreement, shall have extended the period of
time during which the Offer is open, in which event the term "Expiration Date"
shall mean the latest time and date on which the Offer, as so extended by the
Purchaser, shall expire. The Purchaser expressly reserves the right, in its sole
discretion, at any time or from time to time, and regardless of whether or not
any of the events set forth in Section 14 of the Offer to Purchase shall have
occurred, (i) to extend the period of time during which the Offer is open and
thereby delay acceptance for payment of, and the payment for, any Shares, by
giving oral or written notice of such extension to the Depositary and (ii) to
amend the Offer in any other respect by giving oral or written notice of such
amendment to the Depositary. The Purchaser shall not have any obligation to pay
interest on the purchase

                                       2
<PAGE>
price for tendered Shares, whether or not the Purchaser exercises its right to
extend the Offer. There can be no assurance that the Purchaser will exercise its
right to extend the Offer. Any such extension will be followed by a public
announcement thereof no later than 9:00 a.m., New York City time, on the next
business day after the previously scheduled Expiration Date. During any such
extension, all Shares previously tendered and not withdrawn will remain subject
to the Offer, subject to the right of a tendering shareholder to withdraw such
shareholder's Shares.

    The Purchaser may also elect to provide a subsequent offering period of
three business days to 20 business days after the Expiration Date, pursuant to
Rule 14d-11 under the Exchange Act (a "Subsequent Offering Period"). If the
Purchaser elects to provide a Subsequent Offering Period, the subsequent offer
will be for all outstanding Shares and the Purchaser will immediately accept and
promptly pay for all Shares as they are tendered during such Subsequent Offering
Period, offering the same form and amount of consideration offered by the
Purchaser for validly tendered Shares during the initial offering period.

    Except as otherwise provided below, tenders of Shares are irrevocable.
Shares tendered pursuant to the Offer may be withdrawn at any time prior to the
Expiration Date and, unless previously accepted for payment and paid for by the
Purchaser pursuant to the Offer, Shares may also be withdrawn at any time after
May 14, 1999. For a withdrawal to be effective, a written or facsimile
transmission notice of withdrawal must be timely received by the Depositary at
one of its addresses set forth on the back cover of the Offer to Purchase and
must specify the name of the person having delivered the Shares to be withdrawn,
the number of Shares to be withdrawn and the name of the registered holder of
the Shares to be withdrawn, if different from the name of the person who
tendered the Shares. If certificates for Shares have been delivered or otherwise
identified to the Depositary, then, prior to the physical release of such
certificates, the serial numbers shown on such certificates must be submitted to
the Depositary and, unless such Shares have been tendered by an Eligible
Institution (as defined in Section 2 of the Offer to Purchase), the signatures
on the notice of withdrawal must be guaranteed by an Eligible Institution. If
Common Shares have been tendered pursuant to the procedures for book-entry
transfer as set forth in Section 2 of the Offer to Purchase, any notice of
withdrawal must also specify the name and number of the account at the
Book-Entry Transfer Facility to be credited with the withdrawn Common Shares and
otherwise comply with the Book-Entry Transfer Facility's procedures. Withdrawals
of tenders of Shares may not be rescinded, and any Shares properly withdrawn
will thereafter be deemed not validly tendered for purposes of the Offer.
However, withdrawn Shares may be re-tendered by again following one of the
procedures described in Section 2 of the Offer to Purchase at any time prior to
the Expiration Date. All questions as to the form and validity (including time
of receipt) of notices of withdrawal will be determined by the Purchaser, in its
sole discretion, whose determination will be final and binding. Notwithstanding
the foregoing, no withdrawal rights shall apply during any Subsequent Offering
Period in accordance with Rule 14d-7(a)(2) under the Exchange Act.

    The Offer to Purchase and the related Letter of Transmittal and other
relevant materials will be mailed to record holders of Shares and furnished to
brokers, dealers, banks, trust companies and similar persons whose names, or the
names of whose nominees, appear on the shareholder lists or, if applicable, who
are listed as participants in a clearing agency's security position listing, for
subsequent transmittal to beneficial owner of Shares.

    The information required to be disclosed by Rule 14d-6(d)(1) of the
Securities Exchange Act of 1934 is contained in the Offer to Purchase and is
incorporated herein by reference.

    THE OFFER TO PURCHASE AND LETTER OF TRANSMITTAL CONTAIN IMPORTANT
INFORMATION WHICH SHOULD BE READ BEFORE ANY DECISION IS MADE WITH RESPECT TO THE
OFFER.

FOR IMMEDIATE RELEASE

March 16, 2000

            GYRUS GROUP PLC COMMENCES TENDER OFFER FOR ALL COMMON AND
                 PREFERRED STOCK OF EVEREST MEDICAL CORPORATION

Minneapolis, March 16 -- Gyrus Group PLC, a public limited company organized
under the laws of England and Wales, and Everest Medical Corporation (NASDAQ:
EVMD) today announced that Gyrus Group has commenced a tender offer for all
outstanding shares of common and preferred stock of Everest Medical. This tender
offer is being commenced as part of Gyrus Group PLC's proposed acquisition of
Everest Medical under the terms of a merger agreement signed and announced on
February 23, 2000. Gyrus Group PLC, a worldwide leader in RF surgical systems,
is located in the United Kingdom. Everest Medical is a leading developer,
manufacturer and marketer of innovative RF surgical solutions for less invasive
surgery markets.

Under the terms of the tender offer, a subsidiary of Gyrus Group is offering
to purchase all outstanding shares of common and preferred stock of Everest
Medical at a per share offer price of $4.85 per share in cash with an
aggregate purchase price of approximately $51.6 million. This per share offer
price is the same price shareholders of Everest Medical will receive in the
merger. If this tender offer is successful, Everest Medical will merge with a
subsidiary of Gyrus Group. The tender offer will commence today and is
scheduled to expire at 12:00 noon, Eastern Standard Time, on April 13, 2000,
unless extended. The tender offer is subject to certain customary conditions,
including that holders of at least a majority of an aggregate of the
outstanding shares of common and preferred stock agree to tender their
shares. In addition, the tender offer is subject to the completion of a
placing and offering of Gyrus Group shares in the United Kingdom. This
placing and open offer has been fully underwritten by Nomura International
plc. The proceeds of this placing and offering will be used to fund the
tender offer.

The Board of Directors of Everest Medical, upon the unanimous recommendation
of a Special Committee of the Board comprised of non-employee directors, has
unanimously approved the tender offer and the merger and recommends that
shareholders of Everest Medical tender their shares in the tender offer. The
Special Committee also received an opinion from Dougherty & Company LLC, its
financial advisor, that the Gyrus Group offer is fair to Everest Medical
shareholders from a financial point of view.

Gyrus Group has filed with the Securities and Exchange Commission and has mailed
to shareholders of Everest Medical an offer to purchase and other documents in
connection with the tender offer. Everest Medical has also filed with the
Securities and Exchange Commission and has mailed to its shareholders its
statement of recommendation of the tender offer.

                                    RECITALS

    WHEREAS, Parent and Company have agreed that Parent shall acquire Company by
causing Newco, which has been formed for the express purpose of consummating the

                                   ARTICLE I
                                THE TENDER OFFER

    After the date hereof, Parent may elect to cause Newco to make the Tender
Offer, upon the terms and subject to the conditions set forth in this Agreement.
The decision by Parent to cause Newco to make the Tender Offer shall be in the
sole discretion of Parent and neither Parent nor Newco shall have any obligation
to make or commence the Tender Offer; PROVIDED THAT, if Parent elects not to
cause Newco to make the Tender Offer, Parent shall otherwise remain obligated to

obligation of Newco to accept for payment, and pay for, any shares of Company
Common Stock and Company Preferred Stock tendered pursuant to the Tender Offer
shall be subject to those terms and conditions determined by Parent and Newco in
their discretion in connection with such Tender Offer (any of which may be
waived in whole or in part by Newco in its sole discretion) (the "TENDER OFFER
CONDITIONS").

    (b) Newco may, without the consent of Company, (A) extend the Tender Offer,
if at the scheduled or extended expiration date of the Tender Offer any of the
Tender Offer Conditions shall not be satisfied or waived, until such time as
such conditions are satisfied or waived, (B) extend the Tender Offer for any
period required by any rule, regulation, interpretation or position of the SEC
or the staff thereof applicable to the Tender Offer or any period required by
applicable law, (C) extend the Tender Offer on one or more occasions for an
aggregate period of not more than ten (10) business days beyond the latest
expiration date described in clauses (A) and (B) of this sentence, if on such
expiration date there shall not have been tendered at least 90% of the
outstanding shares of each class of Company Common Stock and Company Preferred
Stock, or (D) extend the Tender Offer beyond the initial expiration date to
include a "SUBSEQUENT OFFERING PERIOD" as such term is defined in Rule 14d-11 of
the rules and regulations of the SEC; PROVIDED HOWEVER, that Newco may not
extend the Tender Offer beyond July 31, 2000 without the consent of Company.
Subject to the terms and conditions of the Tender Offer and this Agreement,
Newco shall accept for payment, and pay for, all shares of Company Common Stock
and Company Preferred Stock validly tendered and not withdrawn pursuant to the
Tender Offer that Newco becomes obligated to accept for payment and pay for,

extent that such information shall have become false or misleading in any
material respect, and Newco shall take all steps

security position listings and computer files and all other information in
Company's possession or control regarding the beneficial owners of shares of

such information and assistance (including updated lists of shareholders,
security position listings and computer files) as Newco may reasonably request
in communicating the Tender Offer to the holders of shares of Company Common
Stock and Company Preferred Stock. Subject to the requirements of applicable
law, and except for such steps as are necessary to disseminate the Tender Offer
Documents and any other documents necessary to

                                       3

information contained in any such labels, listings and files, will use such
information only in connection with the Tender Offer and the Merger and, if this
Agreement shall be terminated, will deliver, and will use their best efforts to
cause their agents to deliver, to Company all copies and any extracts or
summaries from such information then in their possession or control.

<PAGE>
    referred to together as the "PREFERRED STOCK CERTIFICATES" and, together
    with the Common Stock Certificates, as the "CERTIFICATES".

        (vi) Promptly after the date hereof, Company shall take all actions
    necessary to procure, on or before the expiration of the Tender Offer, in
    the event that Parent elects to cause Newco to make the Tender Offer, or, on
    or before the Effective Time, in the event that Parent does not elect to
    cause Newco to make the Tender Offer, from each holder of shares of Company
    Preferred Stock an agreement, in form and substance satisfactory to Parent,
    that, immediately prior to the Effective Time, such shares of Company
    Preferred Stock shall be converted into a right of such holder to receive
    from Parent the consideration described in this Section 2.05(c).

    (d) DISSENTING SHARES.  The holders of Dissenting Shares, if any, shall be
entitled to payment for such shares only to the extent permitted by and in
accordance with the provisions of the MBCA; PROVIDED, HOWEVER, that if, in
accordance with the applicable provisions of the MBCA, any holder of Dissenting
Shares shall forfeit such right to payment of the fair cash value of such
shares, such shares shall thereupon be deemed to have been converted into and to
have become exchangeable for, as of the Effective Time, the right to receive the
Merger Consideration applicable thereto as provided in Section 2.05(b) or (c),
as the case may be.

    2.06.  COMPANY EQUITY PLANS.  Prior to the Effective Time, Company shall
terminate Company's 1986 Incentive Stock Option Plan, 1986 Non-Statutory Stock
Option Plan, 1992 Stock Option Plan and 1997 Stock Option Plan (collectively,
the "COMPANY EQUITY PLANS"), and, in connection therewith, shall provide written
notice to each holder of a then outstanding stock option or other right (each,
an "OPTION") to purchase shares of Company Common Stock pursuant to the Company
Equity Plans (whether or not such Option is then vested or exercisable), that
such Option shall be, as of the date of such notice, fully vested and
exercisable in full and that such Option shall terminate at the Effective Time
and that, if such Option is not exercised or otherwise terminated before the
Effective Time, such holder shall be entitled to receive in cancellation of such
Option a cash payment from Parent promptly after the Effective Time, in an
amount equal to the excess of the Common Stock Merger Consideration over the per
share exercise price of such Option, if any, multiplied by the number of shares
covered by such Option (the "OPTION SETTLEMENT AMOUNT"), subject to tax
withholding as required by applicable law. The Company Disclosure Schedule
includes a complete listing of Options held by each optionee (including the date
of grant, the number of shares issuable upon exercise of the Option, the
exercise price per share, and the Option Settlement Amount to which the Optionee
is entitled). Except as otherwise provided in this Section 2.06, Company shall
not grant or amend any Option after the date hereof. Company hereby represents
and warrants to Parent that the number of shares of Company Common Stock subject
to issuance pursuant to the exercise of Options issued and outstanding under the
Company Equity Plans is, and shall be as of the Effective Time, not in excess of
1,386,154. To the extent that the cancellation of any Option pursuant to this
Section 2.06(a) requires the agreement of the holder of such Option under a
Company Equity Plan, Company shall enter into an agreement with such holder
providing for the cancellation of such Option in consideration for the receipt
by such holder of the applicable Option Settlement Amount with respect to such
Option.

    2.07.  WARRANTS.  Prior to the Effective Time, Company shall take all
actions necessary to procure, on or before the expiration of the Tender Offer,
in the event that Parent elects to cause Newco to make the Tender Offer, or, on
or before the Effective Time, in the event that Parent does not elect to cause
Newco to make the Tender Offer, from each holder of an outstanding warrant
(each, a "WARRANT") to purchase shares of Company Common Stock an agreement
that, as of the Effective Time, such Warrant shall be converted into a right of
such holder to receive from Parent promptly after the Effective Time the
consideration set forth in the next sentence. Each holder of a Warrant shall be
entitled to receive from Parent in respect of the shares of Company Common Stock
to be issued upon the exercise of such Warrant, an amount in cash, without
interest (the "WARRANT CONSIDERATION"), equal to the product of (i) the number
of shares of Company Common Stock subject to such Warrant immediately prior to
the Effective Time and (ii) the excess, if any, by which the Common Stock Merger
Consideration exceeds the exercise price per share applicable to such Warrant.
Company hereby represents and warrants to Parent that the number of

                                       6
<PAGE>
shares of Company Common Stock subject to issuance pursuant to the Warrants is,
and shall be as of the Effective Time, 577,897.

    2.08.  DISSENTING SHARES.

    (a) Notwithstanding any provision of this Agreement to the contrary, holders
of Company Common Stock and Company Preferred Stock which are entitled to
dissenter's rights in connection with the Merger under the MBCA (collectively,
the "DISSENTING SHARES") shall not be converted into or represent the right to
receive the Merger Consideration applicable to such shares. Such shareholders
shall be entitled to receive payment of the fair market value of such Dissenting
Shares held by them in accordance with the provisions of the MBCA, except that
all Dissenting Shares held by shareholders who shall have failed to perfect or
who effectively shall have withdrawn or lost their rights to the payment of fair
market value for such shares under the MBCA shall thereupon be deemed to have
been converted into and to have become exchangeable for, as of the Effective
Time, the right to receive the Merger Consideration applicable to such shares,
without any interest thereon, upon surrender, in the manner provided in
Section 2.09, of the certificate or certificates that formerly evidenced such
shares.

    (b) Company shall give Parent (i) prompt notice of any demand for payment of
fair market value received by Company, the withdrawals of any such demand, and
any other instrument served pursuant to the MBCA and received by Company and
(ii) the opportunity to direct all negotiations and proceedings with respect to
demands for payment of fair market value under the MBCA. Company shall not,
except with the prior written consent of Parent, make any payment with respect
to any demands for payment of fair market value or offer to settle or settle any
such demands.

    2.09.  EXCHANGE OF CERTIFICATES.

    (a) From and after the Effective Time, a bank or trust company to be
designated by Parent (the "EXCHANGE AGENT") shall act as exchange agent in
effecting the exchange of the Merger Consideration for Certificates which, prior
to the Effective Time, represented shares of Company Common Stock or Company
Preferred Stock, as the case may be, entitled to payment pursuant to
Section 2.05 hereof. At or immediately prior to the Effective Time, Parent shall
deposit with the Exchange Agent the aggregate Merger Consideration necessary to
make the payments to be made as contemplated by Section 2.05 hereof on a timely
basis (the "DEPOSIT AMOUNT") in trust for the benefit of the holders of
Certificates. Upon the surrender of each such Certificate and the issuance and
delivery by the Exchange Agent of the Merger Consideration applicable thereto in
exchange therefor, such Certificate shall forthwith be cancelled. Until so
surrendered and exchanged, each such Certificate (other than Certificates
representing shares held by Parent or Company or any direct or indirect
Subsidiary of Parent and Dissenting Shares) shall represent solely the right to
receive the Merger Consideration applicable thereto, without interest,
multiplied by the number of shares represented by such Certificate. Promptly
after the Effective Time, the Exchange Agent shall mail to each record holder of
Certificates which immediately prior to the Effective Time represented shares a
form of letter of transmittal and instructions for use in surrendering such
Certificates and receiving the Merger Consideration applicable thereto. Upon the
surrender to the Exchange Agent of such an outstanding Certificate together with
such letter of transmittal, duly completed and validly executed in accordance
with the instructions thereto, and such other documents as may be required
pursuant to such instructions, the holder shall receive the Merger Consideration
applicable thereto, without any interest thereon and such Certificate shall be
cancelled. If any Merger Consideration is to be paid to a name other than the
name in which the Certificate representing shares surrendered in exchange
therefor is registered, it shall be a condition to such payment or exchange that
the Person requesting such payment or exchange shall pay to the Exchange Agent
any transfer or other taxes required by reason of the payment of such Merger
Consideration to a name other than that of the registered holder of the
Certificate surrendered, or such Person shall establish to the satisfaction of
the Exchange Agent that such tax has been paid or is not applicable.
Notwithstanding the foregoing, neither the Exchange Agent nor any party hereto
shall be liable to a holder of shares for any Merger Consideration delivered to
a public official pursuant to applicable abandoned property, escheat or similar
laws.

                                       7
<PAGE>
    (b) Parent shall not be entitled to the return of any of the Deposit Amount
in the possession of the Exchange Agent relating to the transactions described
in this Agreement until the date which is 180 days after the Effective Time.
Thereafter, each holder of a Certificate representing a share may surrender such
Certificate to the Surviving Corporation and (subject to applicable abandoned
property, escheat and similar laws) receive in exchange therefor the Merger
Consideration applicable thereto, without any interest thereon, but shall have
no greater rights against the Surviving Corporation than may be accorded to
general creditors of the Surviving Corporation.

    (c) At and after the Effective Time, the holders of Certificates to be
exchanged for the Merger Consideration applicable thereto pursuant to this
Agreement shall cease to have any rights as shareholders of Company except for
the right to surrender such holder's Certificates in exchange for payment of the
Merger Consideration applicable thereto, and after the Effective Time there
shall be no transfers on the stock transfer books of the Surviving Corporation
of the shares which were outstanding immediately prior to the Effective Time.
If, after the Effective Time, Certificates are presented to the Surviving
Corporation or the Exchange Agent, they shall be cancelled and exchanged for the
Merger Consideration applicable thereto, as provided in this Article II, subject
to applicable law in the case of Dissenting Shares.

    (d) If 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 subject to such other conditions as the Parent
may impose, the Exchange Agent shall pay in exchange for such lost, stolen or
destroyed Certificate the Merger Consideration deliverable in respect of such
Certificate as determined in accordance herewith. When authorizing such payment
of the Merger Consideration in exchange for such Certificate, the Parent (or any
authorized officer thereof) may, in its reasonable discretion and as a condition
precedent to the issuance thereof, require the owner of such lost, stolen or
destroyed Certificate to deliver to the Surviving Corporation a bond in such sum
as the Surviving Corporation may reasonably require as indemnity against any
claim that may be made against Parent, the Surviving Corporation or the Exchange
Agent with respect to the Certificate alleged to have been lost, stolen or
destroyed.

    (e) The provisions of this Section 2.09 shall also apply to Dissenting
Shares that lose their status as such, except that the obligations of Exchange
Agent under this Section 2.09 shall commence on the date of loss of such status.

    2.10.  SUPPLEMENTARY ACTION.  If, at any time after the Effective Time, any
further assignments or assurances in law or any other things are necessary or
desirable to vest or to perfect or confirm of record in the Surviving
Corporation the title to any property or rights of either Company or Newco, or
otherwise to carry out the provisions of this Agreement, the officers and
directors of the Surviving Corporation are hereby authorized and empowered, in
the name of and on behalf of Company and Newco, to execute and deliver any and
all things necessary or proper to vest or to perfect or confirm title to such
property or rights in the Surviving Corporation, and otherwise to carry out the
purposes and provisions of this Agreement.

    2.11.  POSSIBLE ALTERNATIVE STRUCTURE.  Notwithstanding any other provision
of this Agreement to the contrary, prior to the Effective Time, Parent shall be
entitled to revise the structure of the transaction to provide that Newco shall
be merged with and into Company at the Effective Time, with Company as the
surviving corporation of the Merger. Notwithstanding the foregoing or any other
provision of this Agreement to the contrary, Parent and Company may jointly
elect prior to the Effective Time, to substitute an alternative structure for
the accomplishment of the transactions contemplated by this Agreement. Parent
and Company agree that this Agreement shall be appropriately amended in order to
reflect any alternative structure.

Minnesota. Company has all requisite corporate power and authority to own,
operate and lease its properties and to carry on its business as it is now being
conducted. Company is duly qualified as a foreign corporation, and is in good
standing, in each jurisdiction where the character of its properties owned or
held under lease or the nature of its activities makes such qualification
necessary, other than in jurisdictions where the failure to be so qualified,
individually and in the aggregate, has not had and would not reasonably be
expected to have a Material Adverse Effect. Company has no Subsidiaries and no
direct or indirect equity or related interest in any partnership, corporation,
limited liability company, joint venture, business association or other entity.

    3.02.  ARTICLES OF ORGANIZATION; BYLAWS; AND STOCK TRANSFER

of rights to purchase or receive stock, cash or other assets upon the
acquisition or proposed acquisition of shares of Company Common Stock or Company
Preferred Stock by a Person (a "RIGHTS PLAN"), nor has Company's Board of

requisite corporate power and authority to enter into this Agreement and to

contemplated hereby. The execution and delivery of this Agreement by Company,
the performance by Company of its obligations hereunder and the consummation by

authorized by the Special Committee and Board of Directors of Company and no

    of, or the loss of a benefit under, or result in the creation of a lien,
    security interest, charge or encumbrance on any of the properties or assets
    of Company pursuant to (i) the Articles of Organization (or other charter
    document) or Bylaws of Company, or (ii) any contract, lease, agreement,

    losses, rights of termination, amendment, cancellation or acceleration,
    liens, security interests, charges or encumbrances as to which requisite
    waivers have been obtained or which individually or in the aggregate would
    not have a Material Adverse Effect; and

        (B) do not and will not result in any grant of rights to any other party
    under the Articles of Organization (or other charter document) or Bylaws of
    Company or restrict or impair the ability of the Parent or any of its
    Subsidiaries to vote, or otherwise exercise the rights of a shareholder with
    respect to shares of Company that may be directly or indirectly acquired or
    controlled by them.

or the consummation by Company of the transactions contemplated by this
Agreement and (ii) no waiver, consent, approval, order or authorization of any
Governmental Entity is required to be obtained in

<PAGE>
connection with the execution or delivery of this Agreement by Company or the
performance by Company of its obligations hereunder or the consummation by
Company of the transactions contemplated by this Agreement, other than such
notices, reports, registrations, declarations, filings, waivers, consents,
approvals, orders, or authorizations, the absence of which would not,
individually and in the aggregate, subject Company to any criminal penalties or
otherwise reasonably be expected to have a Material Adverse Effect.

thereto) and present fairly in all material respects the consolidated financial
position of Company as of the dates thereof and the consolidated results of
their operations and cash flows as of the dates and for the fiscal periods
indicated therein. The books and records of Company have been, and are being,
maintained in accordance with GAAP and applicable legal and regulatory
requirements. Each SEC Report filed with the SEC complied in all material
respects with the then applicable requirements of the Exchange Act and the
Securities Act of 1933, as amended (the "SECURITIES ACT"), and the rules and
regulations of the SEC promulgated thereunder and as of the date of each such
SEC Report 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 therein, in light of the circumstances under which they were made,
not misleading.

    3.07.  NO DEFAULT.  Company is not in default or violation (and no event has
occurred which with or without notice, the lapse of time or the happening or
occurrence of any other event would constitute a default or violation) of any
term, condition or provision of (i) its Articles of Organization (or other
charter document) or Bylaws, or (ii) any contract, lease, agreement, license,
note, bond, mortgage, indenture, deed of trust or other instrument or obligation
to which Company is a party or by which Company or any of its properties or
assets may be bound (nor to the knowledge of Company is any other party thereto
in breach thereof or default thereunder), except for defaults, violations or
breaches that would not, individually or in the aggregate, have a Material
Adverse Effect.

    3.08.  COMPLIANCE WITH LAW.  Except as set forth in Section 3.08 of the
Company Disclosure Schedule, Company is in compliance, and has conducted its
business so as to comply with, all statutes, laws, ordinances, rules,

Agreement all of Company's licenses and permits (collectively, the "LICENSES").
To the best of Company's knowledge, the Licenses are the only permits and
licenses required by Company to operate its business as currently conducted.

incurred since December 31, 1999 in the ordinary course of business, incurred in
connection with this Agreement or identified in Section 3.11 of the Company
Disclosure Schedule, Company has no liabilities or obligations of any nature
whatsoever (whether absolute, accrued, fixed, contingent, liquidated,
unliquidated or otherwise), required by generally accepted accounting principles
to be recognized or disclosed on a consolidated balance sheet of Company or in
the notes thereto, other than those recognized or disclosed in the Company
Balance Sheet or disclosed in the 1999 10-KSB.

    3.12.  LITIGATION.  Except as set forth in Section 3.12 of the Company
Disclosure Schedule, there is no action, suit, investigation or proceeding
pending against, or to the knowledge of Company, threatened against or
affecting, Company or any of its properties as to which there is a reasonable
possibility of an adverse determination and which if determined adversely to
Company could be expected to have a Material Adverse Effect and there is no
judgment, decree, writ, injunction, award, ruling or order of any Governmental
Entity or arbitrator outstanding against Company having, or which, insofar as

Section 3.12 of the Company Disclosure Schedule includes a list of all
litigation pending against Company as of the date of this Agreement. Company has
made available to Parent correct and complete copies of all correspondence
prepared by its counsel for Company's auditors in connection with the last

are no actions, suits or proceedings pending or, to the knowledge of Company,
threatened against Company arising out of or in any way related to this
Agreement, the Tender Offer, the Merger or any of the transactions contemplated
hereby or thereby.

    3.13.  ERISA.

    (a) Section 3.13 of the Company Disclosure Schedule lists each "employee
benefit plan," as defined in Section 3(3) of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA"), and all other written or oral plans
or agreements involving direct or indirect compensation (including any
employment agreements entered into between Company and any employee or former
employee of Company, but excluding worker's compensation, unemployment
compensation and other government-mandated programs) currently or previously
maintained, contributed to or entered into by Company or any ERISA Affiliate
thereof for the benefit of any employee or former employee of Company under
which Company or any ERISA Affiliate thereof has or may have any present or
future obligation or liability (collectively, the "COMPANY EMPLOYEE PLANS"). For
purposes of this Section 3.13, "ERISA AFFILIATE" shall mean any entity which is
a member of (i) a "controlled group of corporations," as defined in

                                       12
<PAGE>
Section 414(b) of the Internal Revenue Code of 1986, as amended (the "CODE"),
(ii) a group of entities under "common control," as defined in Section 414(c) of
the Code or (iii) an "affiliated service group," as defined in Section 414(m) of
the Code or treasury regulations promulgated under Section 414(o) of the Code,
any of which includes Company. Section 3.13 of Company Disclosure Schedule
identifies the only Company Employee Plans which individually or collectively
would constitute an "employee pension benefit plan," as defined in Section 3(2)
of ERISA (collectively, the "COMPANY PENSION PLANS").

    (b) No Company Pension Plan is subject to Title IV of ERISA, Part 3 of Title
I of ERISA or Section 412 of the Code. No Company Pension Plan constitutes or
has since the enactment of ERISA constituted a "multiemployer plan," as defined
in Section 3(37) of ERISA. To the best of Company's knowledge, nothing done or
omitted to be done and no transaction or holding of any asset under or in
connection with any Company Employee Plan has or is likely to make Company or
any officer or director of Company subject to any material liability under Title
I of ERISA or liable for any material tax pursuant to Section 4975 of the Code.

    (c) Each Company Pension Plan which is intended to be qualified under
Section 401(a) of the Code is so qualified and has been so qualified during the
period from its adoption to date. To the best of Company's knowledge, nothing
has occurred prior to or since the adoption of the Company Pension Plan to cause
the loss of such qualification under the Code, but such Plan has not been
resubmitted to the Internal Revenue Service with respect to any amendments
reflecting changes in the applicable law or other changes for which the remedial
amendment period has not expired as of the Closing Date. Each trust forming a
part of a Company Pension Plan is exempt from tax pursuant to Section 501(a) of
the Code. Each Company Employee Plan has been maintained in material compliance
with its terms and with the applicable requirements of ERISA and the Code.

    (d) Each employment, severance or other similar contract, arrangement or
policy and each plan or arrangement (written or oral) providing for insurance
coverage (including any self-insured arrangements), vacation benefits, severance
or severance-type benefits, disability benefits, death benefits, hospitalization
benefits, retirement benefits, deferred compensation, profit-sharing, bonuses,
stock options, stock purchase, phantom stock, stock appreciation or other forms
of incentive compensation or post-retirement insurance, compensation or benefits
which (i) is not a Company Employee Plan, (ii) is entered into, maintained or
contributed to, as the case may be, by Company, and (iii) covers any employee or
former employee of Company, is herein referred to as a "COMPANY BENEFIT
ARRANGEMENT" and collectively as the "COMPANY BENEFIT ARRANGEMENTS." All Company
Benefit Arrangements are listed in Section 3.13 of the Company Disclosure
Schedule. Each Company Benefit Arrangement has been maintained in material
compliance with its terms and with the requirements prescribed by any and all
statutes (including but not limited to the Code), orders, rules and regulations
which are applicable to such Company Benefit Arrangements.

    (e) There has been no amendment to, written interpretation or announcement
(whether or not written) by Company relating to, or change in employee
participation or coverage (other than as required under the terms of any such
plan) under, any Company Employee Plan or Company Benefit Arrangement which
would increase the expense of maintaining such Company Employee Plan or Company
Benefit Arrangement above the level of the expense incurred in respect thereof
for the fiscal year ended December 31, 1999.

    (f) The Company has complied with the requirements of Section 4980B of the
Code with respect to any "qualifying event" (as defined in Section 4980B(f)(3)
of the Code) occurring prior to and including the Closing Date, except where
failure to be in compliance individually and in the aggregate has not had and
would not reasonably be expected to have a Material Adverse Effect and, to
Company's knowledge, no tax payable on account of Section 4980B of the Code has
been incurred with respect to any current or former employees of Company.

    (g) There is no term of any Company Employee Plan or Company Benefit
Arrangement covering a "disqualified individual" (as defined in Section 280G(c)
of the Code), or of any contract, instrument, agreement or arrangement with any
such disqualified individual, that individually or collectively could

                                       13
<PAGE>
result in a disallowance of the deduction for any "excess parachute payment" (as
defined in Section 280G(b)(i) of the Code) or the imposition of the excise tax
provided in Section 4999 of the Code. The consummation of the transactions
contemplated by this Agreement will not result in any "excess parachute payment"
or the imposition of any such excise tax.

    (h) Company has heretofore delivered to Parent copies of all of Company
Employee Plans, Company Pension Plans and Company Benefit Arrangements listed in
Section 3.13 of Company Disclosure Schedule.

    (i) There is no pending or, to Company's knowledge, threatened legal action,
proceeding or investigation, other than routine claims for benefits, concerning
any Company Employee Plan, Company Pension Plan or Company Benefit Arrangement
or, to the knowledge of Company any fiduciary or service provider thereof and,
to the knowledge of Company, there is no basis for any such legal action or
proceeding.

    (j) No Company Employee Plan or Company Benefit Arrangement provides health,
life or other similar welfare coverages after termination of employment except
to the extent required by applicable state insurance laws and Code
Section 4980B and Title I, Part 6 of ERISA.

    (k) With respect to each Company Employee Plan, Company Pension Plan or
Company Benefit Arrangement for which a separate fund of assets is or is
required to be maintained, full payment has been made of all amounts required of
Company and ERISA Affiliates under the terms of each such Plan or Arrangement or
applicable law, through the Closing Date.

    (l) Company has the power and authority under the terms of the Company
Employee Stock Purchase Plan to terminate that plan prior to the Effective Time
(as provided in Section 5.08) without the consent of any employee.

    3.14.  LABOR MATTERS.  There is no labor strike, dispute, slowdown, stoppage
or lockout actually pending, or threatened against Company. Company is not a
party to or bound by any collective bargaining agreement with any labor
organization applicable to employees of Company. Company has not experienced any
material work stoppage or other material labor difficulty during the two-year
period ending on the date hereof.

    3.15.  TAX RETURNS AND REPORTS.

    (a) Company has timely filed in correct form with the appropriate taxing
authorities all federal, state, county, local and foreign returns, estimates,
information statements, reports and other documents in respect of Taxes (as
defined in Article VIII) required to be filed by Company. All amounts shown due
on such returns have been paid as required by law.

    (b) No assessment that has not been settled or otherwise resolved has been
made with respect to Taxes not shown on the Tax returns, other than such
additional Taxes as are being contested in good faith or which if determined
adversely to Company would not have a Material Adverse Effect. There are no
material disputes pending or written claims asserted for Taxes or assessments
upon Company, nor has Company been requested to give any currently effective
waivers extending the statutory period of limitation applicable to any Federal,
state, county, foreign or local income tax return for any period. No deficiency
in Taxes or other proposed adjustment that has not been settled or otherwise
resolved has been asserted in writing by any taxing authority against any of
Company. No Tax return of Company is now under examination by any applicable
taxing authority. There are no material liens for Taxes (other than current
Taxes not yet due and payable) on any of the assets of Company, except for such
liens for Taxes that would not have a Material Adverse Effect. During the past
five years, no jurisdiction has made any written claim or allegation, or made
any written inquiry pursuant to such a written claim or allegation, that Company
is required to file Tax returns in such jurisdiction for any Tax for which
Company does not presently filed Tax returns in such jurisdiction.

    (c) Adequate provision has been made on the Company Balance Sheet for all
Taxes of Company in respect of all periods through the date hereof.

                                       14
<PAGE>
    (d) As of the date of this Agreement, Company has no ruling requests
currently pending with the Internal Revenue Service.

    (e) Except as set forth in the SEC Reports, Company is not a party to (or
obligated under) any Tax allocation, tax sharing or tax indemnity agreement
which has as a party any Person other than Company.

    (f) Company has withheld and paid all Taxes required to have been withheld
and paid in connection with amounts paid or owing to any employee, consultant,
independent contractor, creditor, shareholder or other party.

    3.16.  COMPANY DEBT.  Section 3.16 of the Company Disclosure Schedule lists
all outstanding Indebtedness of Company as of the date hereof, except for
individual items of indebtedness the principal amount of which do not exceed
$50,000. Section 3.16 of the Company Disclosure Schedule sets forth the amount
of principal and unpaid interest outstanding under each instrument evidencing
Indebtedness of Company, if any, that will accelerate or become due or result in
a right on the part of the holder of such indebtedness (with or without due
notice or lapse of time) to require prepayment, redemption or repurchase as a
result of the execution of this Agreement or the consummation of the
transactions contemplated hereby.

    3.17.  TRADEMARKS, PATENTS AND COPYRIGHTS.

a similar business would, in accordance with good business practice, customarily

or the assets of Company, or (B) 20% or more of any class of equity securities
of Company, (ii) relating to any tender offer or exchange offer that if
consummated would result in any Person beneficially owning 20% or more of any
class of equity securities of Company, or (iii) relating to any merger,
consolidation, business combination, recapitalization, liquidation, dissolution
or similar transaction involving Company, in each case, other than the
transactions contemplated by this Agreement. Immediately following the execution
and delivery of this Agreement by the parties hereto, Company will cease and
cause to be terminated any existing activities, discussions or negotiations with
any parties conducted with respect to the foregoing. Promptly following the
execution of this Agreement by the parties hereto, Company will request each
Person that has, prior to the date of this Agreement, executed a confidentiality
agreement in connection with its consideration of an Acquisition Proposal to
return or destroy all confidential information heretofore furnished to such
Person by or on behalf of Company.

    (b) Except as expressly permitted by this Section 5.05, the Board of
Directors of Company shall not (i) withdraw or modify, or propose publicly to
withdraw or modify, in a manner adverse to Parent, the approval or
recommendation by such Board of Directors of the Merger, the Tender Offer (if
Parent elects to cause Newco to make the Tender Offer) or this Agreement,
(ii) approve or recommend, or propose publicly to approve or recommend, any
Acquisition Proposal, or (iii) cause Company to enter into any letter of intent,
agreement in principle, acquisition agreement or other similar agreement (each,
a "COMPANY ACQUISITION AGREEMENT") related to any Acquisition Proposal, other
than any such agreement entered into concurrently with a termination pursuant to
the next sentence to facilitate such action. Notwithstanding the foregoing, if
at any time the Board of Directors of Company determines in good faith, after
consultation with and receipt of advice from outside counsel, that it is
necessary to do so in order to act in a manner consistent with its fiduciary
duties to Company's shareholders under applicable law, subject to compliance
with paragraph (c) below, the Board of Directors of Company may, in response to
a Superior Proposal which was not solicited by Company and which did not
otherwise result from a breach of this Section 5.05 (subject to this and the
following sentences of this Section 5.05), terminate this Agreement in
accordance with Section 7.01(d) (and concurrently with or after such
termination, if it so chooses, cause Company to enter into any Company
Acquisition Agreement with respect to any Superior Proposal) but only at a time
that is at least after the third business day after delivery of a Company
Notice. For purposes of this Agreement, a "Superior Proposal" means any proposal
made by a third party to acquire, directly or indirectly, including pursuant to
a tender offer, exchange offer, merger, consolidation, business combination,
recapitalization, liquidation, dissolution or similar transaction, for
consideration consisting of cash and/or securities or other property, more than
50% of the combined voting power of the shares of Company Common Stock and
Company Preferred Stock then outstanding or all or substantially all the assets
of Company which (i) the Board of Directors of Company determines in good faith
is reasonably likely to be consummated, taking into account the Person making
the proposal and all legal, financial and regulatory aspects of the proposal,
including any break-up fees, expense reimbursement provisions and conditions to
consummation, and (ii) the Board of Directors of Company determines in good
faith (after consultation with and based upon the advice of its outside
financial advisors) would, if consummated, provide greater value to Company's
shareholders than the transactions contemplated by this Agreement.

    (c) In addition to the obligations of Company as set forth in paragraphs
(a) and (b) of this Section 5.05, Company shall advise the Parent orally and in
writing of any request for non-public

                                       24
<PAGE>
information, any Acquisition Proposal, including all of the material proposed
terms of such Acquisition Proposal, the identity of the third party, or any
decision by Company to take any of the actions permitted in clauses (x) or
(y) of paragraph (a) above (with any such notice referred to as a "COMPANY
NOTICE"). Any such Company Notice will be delivered promptly after (and in no
event later than 24 hours after) receipt of any request for non-public
information or of any Acquisition Proposal and prior to Company taking any of
the actions permitted in clauses (x) or (y) of paragraph (a) above. In addition,
in the event Company intends to enter into a Company Acquisition Agreement
relating to a Superior Proposal, Company will deliver a Company Notice at least
24 hours prior to entering into such Company Acquisition Agreement, which
Company Notice will identify the third party and the material proposed terms of
such Superior Proposal. Company will keep Parent reasonably informed of the
status of any such request or Acquisition Proposal and will update the
information required to be provided in each Company Notice upon the request of
Parent.

    5.06.  PUBLIC ANNOUNCEMENTS.  Parent and Company will consult with each
other before, but will not be required to obtain the other party's consent with
respect to, issuing any press release, any filing with the SEC on Form 8-K or
otherwise making any public statements with respect to this Agreement or the
Merger or the other transactions contemplated hereby, and shall not issue any
such press release, SEC Form 8-K filing or make any such public statement prior
to such consultation, except to the extent that compliance with legal
requirements requires a party to issue a press release or public announcement or
make an 8-K filing prior to such consultation. This Section 5.06 shall supersede
any conflicting provisions in the Confidentiality Agreement.

    5.07.  NOTIFICATION OF CERTAIN MATTERS.

    (a) Company shall give prompt notice (which notice shall state that it is
delivered pursuant to Section 5.07 of this Agreement) in writing to Parent and
Parent shall give prompt notice in writing to Company, of (i) the occurrence, or
failure to occur, of any event which occurrence or failure would be likely to
cause any representation or warranty contained in this Agreement to be untrue or
inaccurate in any material respect at any time from the date of this Agreement
through the Effective Time and (ii) any material failure of Company or Parent,
as the case may be, or of any officer, director, employee or agent thereof, to
comply with or satisfy any covenant, condition or agreement to be complied with
or satisfied by it under this Agreement; provided, however, no such notification
shall affect the representations or warranties of the parties or the conditions
to the obligations of the parties hereunder.

    (b) Company shall give prompt notice in writing (which notice shall state
that it is delivered pursuant to Section 5.07 of this Agreement) to Parent of
any occurrence that has had or is expected to have a Material Adverse Effect.

    5.08.  EMPLOYMENT AND BENEFIT MATTERS.

    (a) From and after the Effective Time, Parent agrees to cause the Surviving
Corporation to provide the employees of Company (the "COMPANY EMPLOYEES") who
remain employed after the Effective Time with the types and levels of employee
benefits which are in the aggregate at least as favorable as those maintained by
Company prior to the Effective Time; PROVIDED, that this obligation shall not
include the Company Employee Stock Purchase Plan or the Company Equity Plans.
Parent will treat, and cause its applicable benefit plans to treat, the service
of Company Employees with Company as service rendered to the Surviving
Corporation for purposes of eligibility to participate, vesting and for other
appropriate benefits but not for benefit accrual.

    (b) Company shall use its reasonable best efforts to cause the employees set
forth on Section 5.08 of the Company Disclosure Schedule (the "DESIGNATED
COMPANY EMPLOYEES") to enter into employment agreements with Parent and the
Surviving Corporation on the terms and conditions set forth in EXHIBIT A hereto
(the "EMPLOYMENT AGREEMENTS").

    (c) The Company Employee Stock Purchase Plan shall be terminated prior to
the Effective Date and Company shall deliver evidence of such termination to
Parent.

                                       25
<PAGE>
    (d) Notwithstanding anything to the contrary contained herein, Parent shall
have sole discretion with respect to the determination as to whether or when to
terminate, merge or continue any employee benefit plans and programs of Company
after the Effective Time.

    5.09.  OFFICERS' AND DIRECTORS' INDEMNIFICATION; INSURANCE.

    (a) The Surviving Corporation agrees that for a period ending on the sixth
anniversary of the Effective Time, the Surviving Corporation will maintain all
rights to indemnification (including with respect to the advancement of expenses
incurred in the defense of any action or suit) existing on the date of this
Agreement in favor of the present and former directors, officers, employees and
agents of Company as provided in Company's Articles of Incorporation and
By-laws, in each case as in effect on the date of this Agreement, and that
during such period, neither the Articles of Incorporation nor the By-laws of the
Surviving Corporation shall be amended to reduce or limit the rights of
indemnity afforded to the present and former directors, officers, employees and
agents of Company, or the ability of the Surviving Corporation to indemnify
them, nor to hinder, delay or make more difficult the exercise of such rights or
indemnity or the ability to indemnify.

    (b) The Surviving Corporation agrees to indemnify to the fullest extent
permitted under its Certificate of Incorporation, its By-laws, and applicable
law the present and former directors, officers, employees and agents of Company
against all losses, damages, liabilities or claims made against them arising
from their service in such capacities prior to and including the Effective Time,
to at least the same extent as such persons are currently permitted to be
indemnified pursuant to Company's Articles of Incorporation and By-laws for a
period ending on the sixth anniversary of the Effective Time.

    (c) Parent will cause to be maintained for a period of four years from the
Effective Time Company's current directors' and officers' insurance and
indemnification policy to the extent that it provides coverage for events
occurring prior to the Effective Time (the "D&O INSURANCE") for all persons who
are directors and officers of Company on the date of this Agreement, so long as
such insurance is available on commercially reasonable terms and the annual
premium therefor would not be in excess of 200% of the last annual premium paid
prior to the date of this Agreement (the "MAXIMUM PREMIUM"). If the existing D&O
Insurance expires, is terminated or cancelled during such three-year period,
Parent will use all reasonable efforts to cause to be obtained as much D&O
Insurance as can be obtained for the remainder of such period for an annualized
premium not in excess of the Maximum Premium, on terms and conditions no less
advantageous than the existing D&O Insurance.

    5.10.  ADDITIONAL AGREEMENTS.

    (a) Subject to the terms and conditions hereof, and Company's and Parent's
respective Board of Directors' fiduciary duties to their respective shareholders
under applicable law, each of the parties to this Agreement agrees to take, or
cause to be taken, all actions, and to do, or cause to be done, all things
necessary, proper or advisable under applicable laws and regulations to
consummate and make effective as promptly as practicable the transactions
contemplated by this Agreement (including consummation of the Merger) and to

or foreign law or regulations, (iii) defend all lawsuits or other legal
proceedings challenging this Agreement or the consummation of the transactions
contemplated hereby, (iv) lift or rescind any injunction or restraining order or
other order adversely affecting the ability of the parties to consummate the
transactions contemplated hereby, (v) effect all necessary registrations and
filings, including, but not limited to, submissions of information requested by

                                       26
<PAGE>
contemplated by this Agreement or the other agreements referred to herein and
(ii) if any state takeover statute or similar statute or regulation becomes
applicable to the Tender Offer, the Merger, this Agreement or any of the other

by this Agreement or the other agreements referred to herein.

    5.11.  COMPANY INDEBTEDNESS.  Prior to the Effective Time, Company shall
cooperate with Parent in taking such actions requested by Parent as are

Agreement and has not been so obtained.

    5.12.  UPDATE OF DISCLOSURE SCHEDULES.  Each party agrees that, with respect
to the representations and warranties of such party contained in this Agreement,
such party shall have the continuing obligation (for notification purposes only)
until the Closing to supplement or amend promptly the Schedules hereto with
respect to any matter hereafter arising or discovered which, if existing or
known at the date of this Agreement, would have been required to be set forth or
described in the Schedules. For all purposes of this Agreement, including
without limitation for purposes of determining whether the conditions set forth
in Section 6.02(a) and 6.03(a) have been fulfilled, the Schedules shall be
deemed to include only that information contained therein on the date of this

the extent permitted under Form 10-QSB under the Exchange Act) and will present

correct copy of the Placing Agreement, between Parent and Nomura International

Issuance; PROVIDED, THAT, Company shall not be required to provide any such
information which is beyond that which is required to be publicly disclosed by

in such materials which shall have become false or misleading in any material
respect.

    5.15.  MEETING OF SHAREHOLDERS OF PARENT.  Promptly after the execution and
delivery of this Agreement, Parent shall duly call, give notice of, convene and

MEETING") to consider and vote upon this Agreement, the Merger and the Share
Issuance, and shall, through its Board of Directors, recommend to its
shareholders the approval and adoption of the Merger, this Agreement, and the

consent of shareholders required by the Companies Act of 1985 to effect the
Merger and the Share Issuance.

    5.16.  DIRECTORS.  Promptly upon the acceptance for payment of shares of
Company Common Stock and Company Preferred Stock by Newco pursuant to the Tender

Directors equal to the product of (i) the total number of directors on Company's
Board of Directors and (ii) the percentage that the number of shares of Company
Common Stock and Company Preferred Stock purchased by Newco in the Tender Offer
bears to the number of shares of Company Common Stock and Company Preferred
Stock outstanding at such time, and Company shall, at such time, cause Newco's
designees to be so elected by its existing Board of Directors; provided, that in
the event that Newco's designees are elected to the Board of Directors of
Company, until the Effective Time such Board of Directors shall have at least
two directors who are directors of Company on the date of this Agreement and who
are not officers or employees of Company (the "INDEPENDENT DIRECTORS") and;
provided further that, in such event, if the number of Independent Directors
shall be reduced below two for any reason whatsoever, the remaining Independent
Director shall designate a person to fill such vacancy who shall be deemed to be
an Independent Director for purposes of this Agreement or, if no Independent
Directors then remain, the other directors of Company on the date hereof shall
designate two persons to fill such vacancies who shall not be officers or
employees of Company, or officers or affiliates of Newco, and such persons shall
be deemed to be Independent Directors for purposes of this Agreement. Subject to
applicable law, Company shall take all action requested by Newco necessary to
effect any such election, including mailing to its shareholders the information
statement containing the information required by Section 14(f) of the Exchange
Act and Rule 14f-1 promulgated thereunder. In connection with the foregoing,
Company will promptly, at the option of Newco, either increase the size of the
Company's Board of Directors and/or obtain the resignation of such number of its
current directors as is necessary to enable Newco's designees to be elected or
appointed to, and to constitute a majority of, Company's Board of Directors as
provided above.

case of Parent, any similar body), may (i) extend the time for the performance
of any of the obligations or other acts of any other party hereto or (ii) waive
compliance with any of the agreements of any other party or with any conditions
to its own obligations. Any agreement on the part of a party hereto to any such
extension or waiver shall be valid only if set forth in an instrument in writing
signed on behalf of such party by a duly authorized officer of such party.
Notwithstanding the above, any waiver given shall not apply to any subsequent
failure of compliance with agreements of the other party or conditions to its

    WHEREAS, Gyrus and Everest recognize the complimentary nature of their
businesses, and the synergies that could be obtained if they could form a

                          FORM OF EMPLOYMENT AGREEMENT

    THIS EMPLOYMENT AGREEMENT (this "AGREEMENT"), dated as of [the Closing
Date], is by and between GOLDEN ACQUISITION CORP., a Delaware corporation (the
"EMPLOYER") and [            ]("EXECUTIVE"). Capitalized terms used herein but
not otherwise defined herein shall have the meanings ascribed to them in that
certain Agreement and Plan of Merger (the "MERGER AGREEMENT"), dated as of
February 23, 2000, by and among Gyrus Group Plc, a public limited company
existing under the laws of England and Wales ("PARENT"), the Employer and
Everest Medical Corporation, a Minnesota corporation (the "COMPANY").

    WHEREAS, pursuant to the terms of the Merger Agreement, at the Effective
Time, the Company was merged (the "Merger") with and into the Employer, with the
Employer as the surviving corporation of the Merger;

    WHEREAS, prior to the Effective Time, the Executive was the [            ]
of the Company;

    WHEREAS, the Executive, in his role with the Company, had integral knowledge
of the Company's operations, policies, customers, personnel and community;

    WHEREAS, the Employer believes that the Executive's services are necessary
to facilitate a smooth, sound and nondisruptive transition following the Merger
and to facilitate the effective operation of the Employer thereafter;

    NOW, THEREFORE, in consideration of the premises and the mutual covenants
contained herein, the parties hereto agree as follows:

    Section1. FREEDOM TO CONTRACT. The Executive represents that he is free to
enter into this Agreement and that he has not made and will not make any
agreement in conflict with this Agreement.

    Section2. EMPLOYMENT.

        (a) The Employer hereby agrees to employ Executive as its
    [            ], upon the terms and conditions set forth in this Agreement.
    Executive agrees that he will, at all times, faithfully, industriously and,
    to the best of his ability, experience and talents, perform all the duties
    and responsibilities that may be required of him as [            ].

        (b) Duties. Subject to the general direction of the Board of Directors
    of the Employer (the "Board"), the Executive shall perform such duties
    consistent with the Executive's position as [            ], as may be
    requested from time to time by the President and Chief Executive Officer of
    the Employer. While employed by the Employer hereunder, the Executive shall
    devote his full business time and best efforts, judgment, skill and
    knowledge exclusively to the advancement of the Employer's interests and to
    the discharge of his duties and responsibilities for the Employer. While
    employed by the Employer hereunder, the Executive shall not engage in any
    other business activity, except as approved by the President and Chief
    Executive Officer in writing. It is agreed, however, that the provisions of
    this Section 2(b) shall not be violated by the Executive's holding of
    directorships or related positions in charitable, educational or
    not-for-profit organizations which do not involve substantial time
    commitments or by passive personal investment activities, provided that such
    positions and activities are not in conflict, and do not otherwise
    interfere, with the Executive's duties and responsibilities to the Employer.

    Section3. TERM OF EMPLOYMENT. Subject to early termination pursuant to
Section7 hereof, the term of employment of the Executive hereunder shall
commence on the Closing Date and shall continue until the third anniversary
thereafter (the "Term"), continuing thereafter on a month to month basis until
terminated by either party by written notice to the other given at least thirty
(30) days prior to such termination.

    Section4. BASE COMPENSATION. The Employer shall pay the Executive, in
accordance with the Employer's payroll practices, a base salary (the "BASE
SALARY"). The Base Salary will be paid at an annual rate of

                                       1
<PAGE>
$[      ] [TO BE 10% INCREASE OVER CURRENT SALARIES OF EACH EXECUTIVE WITH
COMPANY]. The Base Salary may be increased from time to time in the discretion
of the Board of Directors of the Employer and is in addition to the other
benefits set forth herein.

    Section5. STOCK OPTION PLAN. During the Term, the Executive shall be
entitled to participate in a stock option plan adopted by Parent or the Employer
after the date hereof for employees of the Employer.

    Section6. OTHER BENEFITS. During the term of his Agreement, Executive shall
be eligible to receive or participate in all of the insurance, vacation, benefit

    unable to perform his duties under this Agreement for ninety
    (90) successive days.

        (b) For Cause. For "Cause" immediately upon written notice by the
    Employer to the Executive. For purposes of this Agreement, a termination

       jurisdiction of, or pleaded guilty or nolo contendere to, any felony or
       any crime involving moral turpitude;

           (ii) commission of any act of fraud or dishonesty in connection with
       the affairs of the Employer;

       been communicated to Executive; or

           (v) Executive's willful breach of the terms of this Agreement or
       habitual neglect of his duties hereunder.

        (c) WITHOUT CAUSE. Upon written notice by the Employer to the Executive
    for any reason without Cause.

        (d) RESIGNATION. Upon thirty (30) days' written notice by the Executive
    to the Employer.

        (e) RIGHTS AND REMEDIES ON TERMINATION.

           (i) If the Executive's employment hereunder is terminated by the
       Employer (A) pursuant to Section7(a), or (B) without Cause pursuant to
       Section7(c), then in each case, the Executive shall be entitled to
       receive payment, in accordance with the Employer's then current payroll
       practices, of the Executive's Base Salary in effect at the time of such
       termination until the date which is twelve (12) months after such
       termination.

           (ii) If the Executive's employment is terminated other than pursuant
       to termination by the Employer (A) pursuant to Section7(a), or
       (B) without Cause pursuant to Section7(c) hereof, the Executive shall
       only be entitled to receive payment of his Base Salary through the date
       of termination.

          (iii) Except as otherwise set forth in this Section7(e), the Executive
       shall not be entitled to any severance or other compensation after
       termination.

    8. CONFIDENTIAL INFORMATION.

        (a) The Executive shall not, during or after his term of employment, use
    or divulge or communicate to any person, other than with proper authority,
    any of the trade secrets or other

                                       2
<PAGE>
    confidential information of, or relating to, the Employer or any of the
    Employer's affiliates, including Parent, including but not limited to
    details of customers, potential customers, consultants, suppliers, potential
    suppliers, designs, product details, future product details, prices,
    discounting arrangements, specific product applications, existing trade
    arrangements, terms of business and those in the course of negotiation,
    operating systems, pricing and fee structures, financial information,
    inventions, research and development activities and surgical techniques
    which the Executive may have created, developed, received, obtained or had
    access to while employed by the Employer or Company.

        (b) The Executive shall not during the term of his employment with the
    Employer, make, other than for the benefit of the Employer, any records
    (whether recorded on paper, computer memory or discs or otherwise) relating
    to any matter within the scope of the business of the Employer or Parent or
    concerning any of its or their operations nor, either during the term of his
    employment with the Employer or thereafter, use or permit to be used any
    such records otherwise than for the benefit of the Employer, it being
    understood by the Executive that all such records (and copies thereof) in
    the possession or control of the Executive shall be the property of the
    Employer. In the event of the termination of his employment, whether
    voluntary or involuntary and whether by the Employer or the Executive, the
    Executive shall deliver to the Employer all such records (and copies
    thereof).

    9. NON-COMPETITION.

        (a) In further consideration of the Employer's obligations hereunder,
    during the term of the Executive's employment hereunder until the date which
    is one (1) year after termination of the Executive's employment hereunder,
    the Executive will not, directly or indirectly, alone or in any capacity
    with another legal entity, (i) engage, contribute, assist or in any way
    participate in any activity involving or connected with the manufacture or
    distribution of electrosurgical medical devices that is directly competitive
    with the Employer or Parent, wherever located, including products that are
    in development for commercialization or identified in Employer's or Parent's
    present or future business plan, (ii) contact or in any way interfere or
    attempt to interfere with the relationship of the Employer with any current
    or potential customer of the Employer, or (iii) solicit or encourage any
    officer, employee or consultant of the Employer to leave its employ for
    employment by or with any other employer.

        (b) If at any time the provisions of this Section9 shall be determined
    to be invalid or unenforceable, by reason of being vague or unreasonable as
    to area, duration or scope of activity, this Section9 shall be considered
    divisible and shall become and be immediately amended to only such area,
    duration and scope of activity as shall be determined to be reasonable and
    enforceable by the court or other body having jurisdiction over the matter;
    and the Executive agrees that this Section9 as so amended shall be valid and
    binding as though any invalid or unenforceable provision had not been
    included herein.

    10. SPECIFIC PERFORMANCE. Executive acknowledges that a breach of this
Agreement would cause the Employer irreparable injury and damage which could not
be remedied or adequately compensated by damages at law; therefore, Executive
expressly agrees that the Employer shall be entitled, in addition to any other
remedies legally available, to injunctive and/or other equitable relief to
prevent a breach of this Agreement.

    11. MISCELLANEOUS.

        (a) Waiver by the Employer of a breach of any provision of this
    Agreement by Executive shall not operate or be construed as a waiver of any
    subsequent breach by Executive.

        (b) This Agreement shall be binding upon and inure to the benefit of the
    Employer, its successors and assigns, and, as to Executive, his heirs,
    personal representatives, estate, legatees and assigns.

        (c) This Agreement constitutes the entire agreement between the parties
    hereto with respect to the subject matter hereof and supersedes all prior
    agreements whether written or oral relating hereto.

Application Form, and which are accompanied by:

Application Form relates will be treated as not having been taken up and where

comply with the Money Laundering Regulations 1993 in the manner contemplated in
the Circular and the Application Form, the New Shares to which

6.6 Subject to the Company complying with Clause 6.4, if by 3.00 p.m. on the
Dealing Day immediately preceding the date of Admission, there are New Shares
which are not taken up and for which no Placees have been arranged, Nomura shall
itself subscribe (as principal) for such New Shares on the basis of the
information contained in the Circular and the Application Form (other than as to
the time and method of acceptance and payment).

allocated New Shares which are not taken up together with details of any
subscription for such shares to be made by Nomura pursuant to Clause 6.6, and

     Shares and will be issued free from all liens, charges, encumbrances and
     equities.

pay (whether or not Nomura's obligations under this Agreement become
unconditional) all costs and expenses of, or in connection with, the Placing and
Open Offer, the EGM, the allotment and issue of the New Shares and this
Agreement. This shall include (but shall not be limited to) the London Stock
Exchange listing fees, other regulatory fees and expenses, printing and
advertising costs, postage, registrars' and the Receiving Agent's charges, its
own and Nomura's reasonable legal and other out-of-pocket expenses, all

the New Shares and this Agreement. The Company shall immediately on request pay
or reimburse Nomura the amount of any expenses which are to be borne by the
Company and which Nomura (or any subscriber for New Shares) has paid.


                                                                         Page 17

8.5 Where, pursuant to this Agreement, a sum is paid or reimbursed to Nomura,
the Company shall also pay to Nomura in respect of value added tax:

(a)  where the payment or reimbursement constitutes the consideration or part of
     it for any supply of services by Nomura to the Company, such amount as
     equals any value added tax properly payable thereon and on such
     irrecoverable value added tax, if any, as is referred to in (b) below;

(b)  (except where (c) below applies) such amount as equals any value added tax
     charged to Nomura in respect of any cost, charge or expense which gives
     rise to the payment or reimbursement and which Nomura certifies is not
     recoverable by it by repayment or credit, that certificate to be conclusive
     save in the case of manifest error; and

(c)  on any payment or reimbursement in respect of or indemnification for costs,
     charges or expenses incurred by Nomura as agent for the Company, such
     amount as equals the amount included in the costs, charges or expenses in
     respect of value added tax.

RESTRICTIONS ON ACTIONS AND ANNOUNCEMENTS

that no other member of the Group shall, and shall use its reasonable endeavours

     into, which is or may be material in the context of the Placing and Open
     Offer or the underwriting of the New Shares;

     Company (except for the grant of options under, and the allotment and issue

     Revenue approved share option schemes, in each case in accordance with
     normal practice); or

(c)  publish, file, make or despatch any announcement, document or other
     communication which is or may be material in the context of the Placing and
     Open Offer or the underwriting of the New Shares (save for the


                                                                         Page 18

     publication, filing, making or despatch, as the case may be, of the
     Circular, the Form of Proxy, the Application Form and any Supplementary
     Prospectus in accordance with the terms of this Agreement) and any
     announcements or filings required to be filed by the Company, Golden
     Acquisition Corporation or Everest under U.S. Securities Laws in
     connection with the Tender Offer or any of the other transactions
     contemplated by the Merger Agreement.

9.2 The Company undertakes to make all such announcements concerning the Placing
and Open Offer and/or the Acquisition as shall be necessary to comply with the
Listing Rules and/or section 47 of the FSA or which Nomura otherwise reasonably
considers to be necessary or desirable (including, without limitation, for the
purposes of procuring Placees or potential subscribers for any New Shares in
accordance with this Agreement) and Nomura shall be entitled (following
consultation with the Company where practicable) to make any such announcement
if the Company fails (in the opinion of Nomura acting in good faith) promptly to
fulfil its obligations under this Clause 9.2.

9.3 The Company undertakes to do all such reasonable acts and things as are
reasonably necessary to enable the provisions of this Agreement, the Placing,
and the Open Offer to be carried out and given full force and effect.

any of its advisers shall be responsible to the Company or any of its directors
for verifying the accuracy and/or fairness of any information published in the
Circular save in respect of the details of and information contained in the
Circular of the mechanics of the Placing and Open Offer or otherwise published
by the Company in connection with the Placing and Open Offer or the Acquisition,
unless (and only to the extent that) Nomura has taken specific responsibility
for such verification.

9.5 The Company undertakes that it will not agree to any material alteration,
revision or amendment of the terms or conditions of either the Tender Offer or
the Merger Agreement (or any document entered into pursuant thereto) or waive
(in whole or in part) or amend or extend any material condition thereof or grant
any material indulgence thereunder or, subject as aforesaid, proceed to
completion thereof without full satisfaction of all of the terms and conditions
of the Tender Offer or the Merger Agreement or in circumstances where the
Company is aware that it is entitled to rescind or terminate the Tender Offer or
the Merger Agreement without the prior written consent of Nomura.

REPRESENTATIONS AND WARRANTIES

10.1 The Company represents, warrants and undertakes to Nomura in the terms set
out in Schedule 2. The Company acknowledges that Nomura is entering into this
Agreement in reliance on such representations, warranties and undertakings. Each
representation, warranty and undertaking shall be construed separately and shall
not be limited or restricted by reference to or inference from the terms of any
other representation, warranty and undertaking or any other term of this
Agreement.

10.2 The Company shall use its best endeavours not to (and shall use reasonable
endeavours to procure that no other member of the Group nor any of its or their
respective directors, officers, employees or agents shall) cause or (so far as
they are able, using reasonable endeavours) permit any event to occur or omit to
do anything between the date of this Agreement and the date which is five
Dealing Days after, as appropriate, the Acceptance Date or the date on which
Nomura's obligations under this Agreement cease in accordance with Clause 2.3
which would make any statement in Schedule 2 untrue, inaccurate or misleading if
such statement were repeated at such date by reference to the facts and
circumstances then existing.

10.3 The Company shall as soon as reasonably practicable notify Nomura (giving
reasonable details) if it comes to the knowledge of the Company or any Director
that any statement in Schedule 2 was untrue, inaccurate or misleading at the
date of this Agreement or would be untrue, inaccurate or misleading if repeated
by reference to the facts and circumstances existing at any time during the
period referred to in Clause 10.2 or if the Company is in breach of any of its
obligations under this Agreement.

10.4 The Company agrees that Nomura and each Placee shall be entitled (as
subscribers for New Shares) to the same remedies and rights of action against
the Company, and to the same extent, as any person who acquires any New Shares
pursuant to the Open Offer on the basis of the Circular.

10.5 References in this Agreement to a representation, warranty or undertaking
being (or not being) true and accurate or not being (or being) misleading IN ANY
MATERIAL RESPECT shall mean material in the context of the Placing and Open
Offer or the underwriting of the New Shares. In that connection and otherwise in
this Agreement in relation to references to a matter which would or might be
MATERIAL IN THE CONTEXT OF THE UNDERWRITING OF THE NEW SHARES, a matter shall,
without limitation, be deemed to be so material if it would have been material
for disclosure


                                                                         Page 20

to potential Placees had such matter existed when Placees were sought for the
New Shares.

10.6 The representations, warranties and undertakings referred to in Clauses
10.1 to 10.5 shall remain in full force and effect notwithstanding completion of
all matters and arrangements referred to in, or contemplated by, this Agreement.

INDEMNITY

11.1 Nothing in this Clause 11 shall operate to exclude or restrict any duty or
liability of Nomura under the FSA or under the regulatory system (as defined in
the rules of The Securities and Futures Authority Limited) to an extent greater
than permitted by those rules.

11.2 No claim shall be made against Nomura or any subsidiary undertaking or
holding company of Nomura or any subsidiary undertaking of such holding company
or any of their respective shareholders, directors, officers, agents or
employees (each, together with Nomura, referred to in this clause 11 as an
INDEMNIFIED PERSON) to recover any loss, damage, cost, charge or expense which
any member of the Group or any of their respective directors, officers, agents
or employees or any other person may suffer or incur by reason of, or arising
out of, the carrying out by Nomura or on its behalf of its obligations and
services under this Agreement or otherwise in connection with the Placing and
Open Offer or the listing of the New Shares (the COMPANY LOSSES) unless and to
the extent that such loss, damage, cost, charge or expense arises from the
negligence or wilful default of Nomura or that Indemnified Person or any breach
by Nomura of its obligations under this Agreement.

11.3 Notwithstanding anything in Clause 11.2 above, where any Indemnified Person
is the subject of a claim alleging liability in respect of any Company Losses,
then the total amount of such Company Losses recoverable from any such
Indemnified Persons shall be limited to such proportion of the Company Losses as
is finally determined to be just and equitable, having regard to the relative
responsibility of (i) all Indemnified Persons taken together so liable and (ii)
any other person (including for the avoidance of doubt, both the Company (and
any director, employee, agent, subsidiary or affiliate of the Company) and any
other person unrelated to the Company) who is jointly or severally liable for
the Company Losses or any part thereof (a THIRD PARTY). For the avoidance of
doubt, any limitation or exclusion or restriction on the liability of any Third
Party under any jurisdiction, whether arising under statute or contract or
resulting from death,


                                                                         Page 21


<PAGE>


bankruptcy or insolvency shall be ignored for the purposes of determining the
extent of responsibility of that Third Party under (ii) above.

11.4 Without prejudice to Clause 11.3 above, insofar as the Company has engaged
any adviser (a CAPPED ADVISER) on the basis that its liability to the Company
arising out of any default by it or otherwise in connection with the Placing and
Open Offer is subject to any limitation, the liability of each Indemnified
Person to the Company or any other person in respect of the Company Losses shall
not exceed the amount for which that Indemnified Person would have been liable
after deducting any amount which that Indemnified Person would have been
entitled to recover from the capped adviser, in the absence of the limitation of
the capped adviser's liability, by way of contribution to that Indemnified
Person, in respect of the matter concerned.

11.5 The Company undertakes with Nomura for itself and as trustee for each other
Indemnified Person to keep each Indemnified Person indemnified against all
actions, claims or demands brought or made (or threatened to be brought or made)
in any jurisdiction against that Indemnified Person (whether or not successful,
compromised or settled) and against all losses, liabilities, costs, charges and
expenses in any jurisdiction which any Indemnified Person may suffer or incur
(including, without limitation, all such losses, liabilities, costs, charges and
expenses as the Indemnified Person suffers or incurs in investigating,
responding to, preparing for or disputing any actions, claims or demands or in
enforcing its rights under this Clause 11), and whether the same are made,
suffered or incurred (as the case may be) before or after the date of this
Agreement, and which in any case results from, is attributable to or arises in
connection with (directly or indirectly) the matters contemplated by this
Agreement including, without limitation:

(a)  Nomura (or any person on its behalf) carrying out or performing its
     obligations or services under this Agreement or in connection with the
     Placing and Open Offer or the listing of the New Shares;

(b)  the Placing and Open Offer, the allotment and issue of the New Shares, the
     release, despatch, filing or publication (as the case may be) of the Press
     Announcement, the Circular, the Form of Proxy, the Application Form, or any
     Supplementary Prospectus; or

(c)  any breach or alleged breach by the Company of any of its obligations under
     this Agreement or any of the representations, warranties or undertakings
     set out or referred to in this Agreement or otherwise in connection with
     the Placing and Open Offer,


                                                                         Page 22


<PAGE>


unless and to the extent that the relevant action, claim, demand, loss,
liability, cost, charge or expense arises from the negligence or wilful default
of Nomura or that Indemnified Person or any breach by Nomura of its obligations
under this Agreement, PROVIDED THAT an Indemnified Person shall not be entitled
to be indemnified pursuant to this Clause 11.5 in respect of any relevant
action, claim, demand, loss, liability, cost, charge or expense suffered or
incurred which (i) is an unrealised or realised loss in respect of the value of
any New Shares subscribed by an Indemnified Person unless and to the extent that
the same arise or result from any breach by the Company of any of its
obligations under this Agreement, any breach of the representations, warranties
and undertakings referred to in Clause 10.1 or any other neglect or default on
the part of the Company or (ii) arises from the publication of any research note
produced by Nomura (in respect of which the Company shall have no liability).

11.6 Subject to the requirement of a relevant insurer, if any claim is made
against an Indemnified Person for which indemnity is sought under Clause 11.5,
Nomura shall notify the Company as soon as reasonably practicable and consult
with the Company with respect to the handling of the claim.

11.7 If the United Kingdom Inland Revenue or any other taxing authority in any
jurisdiction brings into charge to taxation any sum payable to Nomura or another
Indemnified Person under this Agreement (other than the commissions payable
pursuant to Clause 8.1), then (to the extent that the loss, damage, liability,
cost, charge or expense in respect of which the sum is payable is not allowable
to the relevant Indemnified Person as a deduction for tax purposes against the
sum so payable and in the same accounting period as that in which such sum is
brought into charge to tax) the sum so payable shall be grossed up by such
amount as will ensure that after deduction of the taxation so chargeable there
shall remain a sum equal to the amount that would otherwise be payable under
this Agreement.

11.8 All sums payable to Nomura or another Indemnified Person under this
Agreement shall be paid free and clear of all deductions or withholdings unless
the deduction or withholding is required by law, in which event the Company
shall pay such additional amount as shall be required to ensure that the net
amount received by the Indemnified Person concerned will equal the full amount
which would have been received by it had no such deduction or withholding been
made.

11.9 Notwithstanding any other provision of this Agreement, no Indemnified
Person shall be liable to the Company for, or lose the benefit of the provisions
of this Clause 11 as a result of, any delay in performance or non-performance of
its obligations arising under, out of, or in connection with, this Agreement
where such


                                                                         Page 23

<PAGE>


performance is delayed or prevented by circumstances beyond its reasonable
control.

11.10 The provisions of Clauses 11.1 to 11.9 will remain in full force and
effect notwithstanding the completion of all matters and arrangements referred
to in or contemplated by this Agreement.

11.11 The Company and Nomura undertake with each other that neither the Company
nor Nomura nor any of its employees or agents nor any person acting on its
instructions will engage in (i) any direct selling efforts as such term is
defined in Regulation S of the US Securities Act of 1933, as amended (the
SECURITIES ACT) or (ii) any form of general solicitation or general advertising
as such terms are used in Rule 502 of the Securities Act in respect of the New
Shares.

MISCELLANEOUS

12.1 For the avoidance of doubt, the Company acknowledges and agrees that it is
responsible for any due diligence carried out by the Company or its other
advisers in relation to the Acquisition and the Placing and Open Offer and that
neither Nomura nor any of its advisers shall be responsible to Company or any
Director for any such due diligence in relation thereto or for verifying the
accuracy or fairness of any information published by or on behalf of the Company
in connection with the Acquisition and the Placing and Open Offer save for the
description in such Circular of the mechanics of the Placing and Open Offer.

12.2 The Company agrees that for the purpose of the Placing and Open Offer
(including for the purposes of seeking to procure any Placees for the New
Shares) Nomura shall not be responsible for the provision of or obtaining advice
as to the requirements of applicable laws or regulations of jurisdictions other
than the United Kingdom nor shall it be responsible where it or the Company has
acted in reliance on any advice obtained by the Company in respect thereof.

12.3 The Company acknowledges that the representations, warranties, undertakings
and indemnities contained in this Agreement are given to Nomura in connection
with the Placing and Open Offer and the listing of the New Shares whether in its
capacity as underwriter, financial adviser or sponsor and references in this
Agreement to Nomura shall be construed accordingly.

RECEIVING AGENT

13. The Company confirms that it has instructed the Receiving Agent to act as
receiving agent in connection with the Placing and Open Offer and the EGM and


                                                                         Page 24

the Application Forms and this Agreement as receiving agent.

TIME OF THE ESSENCE

14. Any time, date or period mentioned in this Agreement may be extended by
mutual agreement between the Company and Nomura but as regards any time, date or
period originally fixed, or any time, date or period so extended, time shall be
of the essence.

WAIVER

15.1 Any right or remedy of Nomura under this Agreement shall only be waived or
varied by an express waiver or variation in writing.

15.2 No failure or delay by Nomura in exercising any right or remedy under this
Agreement shall impair such right or remedy or operate or be construed as a
waiver or variation of the right or remedy or preclude its exercise at any
subsequent time. No single or partial exercise of any such right or remedy shall
preclude any other or further exercise of such right or remedy or the exercise
of any other right or remedy. The rights, powers and remedies of Nomura provided
in this Agreement are cumulative and not exclusive of any rights, powers and
remedies provided by law.
