                            STIPULATION OF SETTLEMENT

<PAGE>   2

         This Stipulation of Settlement, including all exhibits attached hereto
("Stipulation"), is made effective as of September 1, 2000, by and among the
Named Plaintiffs (as hereinafter defined in paragraph V.A.9) on behalf of the
Settlement Class (as hereinafter defined in paragraph V.A.19) by and through all
of their attorneys ("Plaintiffs' Counsel" as hereinafter defined in paragraph
V.A.15) in the Litigation (as hereinafter defined in paragraph V.A.8) and Summit
Medical Systems, Inc., n/k/a Celeris Corp. ("Summit") Edward F. Sweeney, Kevin
R. Green, Anthony W. Rees, Kent J. Thiry, Dennis H. Powers, William J. Cavanagh,
and John M. Nehra ("Defendants" as hereinafter defined in paragraph V.A.7).

1. BACKGROUND OF THE LITIGATION

         Plaintiffs commenced this class action pursuant to Sections 10(b) and
20(a) of the Securities Exchange Act of 1934, and Rule 10b-5 promulgated
thereunder, and Sections 11 and 15 of the Securities Act of 1933 on behalf of a
class of persons who purchased shares of Summit Medical Systems, Inc. stock
between August 4, 1995, the date of Summit's initial public offering, and March
3, 1997, the date Summit announced that its financial statements had overstated
its revenues since 1994. The original defendants were Summit and certain
individual officers and directors of Summit and Ernst & Young, the accounting
firm which served as an "expert" in connection with Summit's IPO. The Teachers'
Retirement System of Louisiana brought an individual action against Summit and
the same individual defendants. On September 23, 1997, the Summit defendants
moved to dismiss the claims under Section 10(b) and 20(a) of the Securities
Exchange Act of 1934. In an Order dated June 30, 1998, this Court denied the
Summit defendants' motion to dismiss. Ernst & Young was dismissed as a defendant
in this action and a separate suit was later commenced against them. On July 21,
1998, plaintiffs served their Second Amended Class Action Complaint. On August
21, 1998, the Summit defendants answered the Complaint. The Summit defendants
have

                                       1
<PAGE>   3

produced a substantial number of documents in response to plaintiffs' discovery
requests and plaintiffs did commence deposition discovery. On February 10, 1999,
this Court appointed retired Judge Robert Schefelbein as Special Master for
settlement purposes. The parties met for a mediation before Judge Schefelbein on
May 18, 1999. Informal discussion occurred after the mediation. After several
months of discussion, the parties reached this agreement.

2. PLAINTIFFS' INVESTIGATION

         In connection with their pre-filing investigation and prosecution of
the Litigation, Plaintiffs' Counsel have undertaken an extensive investigation
into the facts and law relating to the matters alleged in the Litigation. They
have reviewed and analyzed publicly available documents and information
including disclosures prior to and during the course of the Litigation by
Summit. In addition to their investigation, Plaintiffs' Counsel have collected
and analyzed data regarding the amount of damages allegedly sustained by the
members of the Settlement Class (as hereinafter defined in paragraph V.A.19). As
a result of this investigation, public disclosures and analysis, the Named
Plaintiffs, the Teachers' Retirement System of Louisiana and Plaintiffs' Counsel
have concluded that the settlement of the Litigation as set forth herein is
fair, reasonable, adequate, and in the best interests of the Settlement Class.

3. REASONS FOR SETTLEMENT

         A. BENEFITS OF SETTLEMENT TO THE SETTLEMENT CLASS.

         Plaintiffs' Counsel have carefully weighed the benefits to the
Settlement Class of the settlement of the Litigation for the consideration
offered by Defendants against the significant costs, risks of recovery, and
delay that continued prosecution of the Litigation would involve. Plaintiffs'
Counsel recognize the expense and length of continued proceedings necessary to
continue the Litigation against Defendants through discovery, trial and appeals
and have considered the problems

                                       2
<PAGE>   4

of proof, and believe that the certainty and amount of this recovery outweigh
the risks of proceeding further with the Litigation.

         B. BENEFITS OF SETTLEMENT TO THE DEFENDANTS.

         Defendants strongly deny any wrongdoing or liability relating to
matters alleged in the Complaint. Nonetheless, defending this case has been
expensive and time-consuming, so that Defendants have concluded that proceeding
further with the Litigation would, in light of the proposed Settlement, be
unduly expensive, burdensome and protracted. Defendants have devoted, and,
unless this Settlement is made, will continue to devote, substantial time,
energy and resources defending the claims asserted by the Named Plaintiffs in
the Litigation. Moreover, while Defendants consider the risk of an adverse
outcome to be unlikely, the damages sought should that risk materialize are
substantial. Defendants have, therefore, concluded that it is in their best
interests to settle the Litigation in the manner and upon the terms and
conditions set forth in this Stipulation.

IV. INTENT OF THE PARTIES TO THIS SETTLEMENT

         The parties to this Stipulation intend, through this stipulation, to
achieve a total peace between and among the class, the Teachers' Retirement
System of Louisiana and Summit and the individual defendants with respect to any
claims asserted, or which could have been asserted against Summit and/or the
individual defendants in this action.

V. TERMS OF THE STIPULATION

         Now, therefore, in consideration of the mutual covenants set forth
herein, it is hereby agreed and stipulated to, by and among the undersigned
parties, and Plaintiffs' Counsel, on behalf of the Settlement Class, the
Teachers' Retirement System of Louisiana and Named Plaintiffs, that the
Litigation shall be settled, compromised and dismissed subject to the approval
of this Court pursuant to Federal Rule of Civil Procedure 23(e) upon and subject
to the following terms and conditions.

such shares during the Settlement Class Period; and, further,

                  c. For purposes of calculating claims for transactions in
Summit common stock: (i) the determination of whether a position was held on
March 3, 1997 is to be made on a "first-in, first-out" basis; (ii) profits on
such transactions in Summit common stock during the Settlement Class Period will

wrongdoing or liability whatsoever. Defendants have denied and expressly
continue to deny all of Plaintiffs' claims. Pursuant to this Stipulation and
Settlement, as Ordered by this Court, and pursuant to Federal Rule of Evidence
408, the Rules of Evidence of the various states and the Rules of Evidence
followed by any quasi-judicial bodies, including regulatory and self-regulatory
organizations, and any other applicable law, rule or regulation, the fact of
entering into or carrying out this Stipulation, the exhibits hereto, and any
negotiations and proceedings related hereto, shall not be construed as, offered
into evidence as, or deemed to be evidence of an admission or concession of
liability by or an estoppel against any of the undersigned parties, and shall
not be offered or received into evidence, or considered, in any action or
proceeding against any undersigned party in any judicial, quasi-judicial,
administrative agency, regulatory or self-regulatory organization, or other
tribunal, or proceeding for any purpose whatsoever, other than to enforce the
provisions of this Stipulation or the provisions of any related agreement,
release, or exhibit hereto, or in the case of any subsequent action against the
Defendants, Named Plaintiffs and any Plaintiffs' Counsel or the Class on any or
all of the Released Claims, in order to support a defense of res judicata,
collateral estoppel, accord and satisfaction, release or other theory of claim
or issue preclusion or similar defense.

         E. CREATION OF THE CLASS SETTLEMENT FUND.

         1. Subject to and in accord with the terms of this Stipulation, and in

The Escrow Agent, or its designee, shall be the administrator of the Class
Settlement Fund and shall file all informational and other tax returns necessary
to report any income earned by the Class Settlement Fund, and shall be
responsible for taking out of the Class Settlement Fund, as and when legally
required, any tax payments (including interest and penalties) due on income
earned by Class Settlement Fund and request refunds, when and if appropriate,
with any such refunds to become part of the Class Settlement Fund. All tax
(including interest and penalties) due with respect to the income earned by the
Settlement Fund shall be paid by the Class Settlement Fund, and Defendants shall
have no responsibility for the foregoing or any other costs, fees, expenses or
payments, other than the payment of a total of $750,000 and 100,000 shares of
Celeris Corp. common stock and 400,000 warrants for Celeris Corp. stock pursuant
to the terms of this Stipulation.

         3. As of the Effective Date, all rights of Defendants in or to the
Class Settlement Fund shall be extinguished, and Defendants shall have no
responsibility or liability with respect to any actions taken or not taken with
respect to the Class Settlement Fund.

         4. Except as provided in this Stipulation, all interest earned on the
Class Settlement Fund shall be added to the Class Settlement Fund and
distributed pursuant to this Stipulation.

         5. As soon as their pro rata share of all Recognized Losses can be
determined, a separate payment shall be made to the Teachers' Retirement System
of Louisiana.

         F. SUPERVISION AND DISTRIBUTION OF THE CLASS SETTLEMENT FUND.

         Defendants shall have no responsibility of any kind with respect to the
distribution of the Court-approved class notice, the allocation of the Net
Settlement Amount or the processing of claims or otherwise with respect to the
administration of this settlement or the Class Settlement Fund.

         G. ATTORNEYS' FEES, EXPERT FEES, COSTS AND EXPENSES.

         Any attorneys' fees, experts' fees, costs and expenses to be sought or
obtained in connection with the settlement shall be paid out of the Class
Settlement Fund, upon authorization of the Court. Defendants shall have no
responsibility or liability whatsoever with respect to such attorneys' fees,
experts' fees, costs and expenses.

         H. COST OF NOTICE AND SETTLEMENT ADMINISTRATION.

         Costs of Notice and Settlement Administration shall include the actual

income earned, and request refunds, when and if appropriate. Defendants shall
have no responsibility or liability whatsoever with respect to these costs.

         I. RELEASE TERMS.

         In consideration of the payment to be made by Defendants and the
issuance of common stock and warrants of Celeris pursuant to this Stipulation,
the Settling Class Members and the Teachers' Retirement System of Louisiana
hereby consent to an Order of the Court effectuating this Stipulation and their
release of Defendants under the following terms:

         1. The Teachers' Retirement System of Louisiana and each Settlement
Class Member, on behalf of themselves and their heirs, executors,
administrators, beneficiaries, predecessors, successors, assigns, and any of
their former and present employees, directors, officers, accountants, agents,
attorneys, representatives, affiliates and subsidiaries, releases and forever
discharges any and all manner of actions, causes of action, suits, obligations,
claims, debts, demands, agreements, promises, liabilities, controversies, costs,
expenses, and attorneys' fees whatsoever, whether in law or in equity and
whether based on federal law, state law, common law, or foreign law right of
action or otherwise, foreseen or unforeseen, matured or unmatured, known or
unknown, accrued or not accrued, which they or any of them, either individually
or as a Settlement Class Member, ever had, now have, or can have, or shall or
may hereafter have against Defendants (as defined in paragraph V.A.4) or any of
them, for, based on, by reason of or arising from or in any way relating to the
Released Claims. Each Settlement Class Member releases and forever discharges
Defendants whether or not such Settling Class Member executes and delivers the
Proof of Claim and Release.

         2. The Settlement Class Members shall be forever barred and enjoined
from commencing, instituting or prosecuting any action or other proceeding in
any court of law or equity,

                                       18
<PAGE>   20

arbitration tribunal or administrative forum, directly, representatively or
derivatively, that asserts against Defendants any claims that relate to or
constitute any of the Released Claims.

         3. The Litigation shall be dismissed with prejudice and on the merits
as to Defendants, and without further costs to any party.

         J. CONDITIONS OF SETTLEMENT.

         1. This Stipulation shall be deemed terminated and canceled, and shall
have no further force and effect whatsoever, if:

                  a. there is no Effective Date;

                  b. the Court denies the motion to enter an Order of
Preliminary Approval of the Settlement and to direct that notice of the
settlement be given, substantially in the forms provided in paragraphs V.B. and
Exhibits A and C hereto, or if such Order is entered, it later is reversed or
modified, whether on appeal or otherwise, so that it is no longer substantially
in the form provided in paragraphs V.B. and Exhibits A and C;

                  c. the Court denies the motion to enter an Order for Final
Judgment in substantially the form provided in paragraphs V.C. and Exhibit B
hereto, or if such a judgment is entered thereon, it is later reversed or
materially modified, whether on appeal or otherwise.

         2. The Defendants shall have the right, at their sole option, to
terminate and cancel this Stipulation if more than 335,000 shares of Summit
common stock held by members of the Settlement Class that are excluded from the
Settlement pursuant to paragraph V.B.6 and Exhibit C, paragraph 5 of this
Stipulation, or otherwise by Order of the Court

                  a. TERMINATION PRIOR TO HEARING.

                  Plaintiffs' Counsel shall notify Defendants of the number of
shares electing to opt out of the Settlement within (5) five business days after
the date by which timely requests for exclusion

                                       19
<PAGE>   21

must be received, in accordance with this Stipulation. If the number of shares
electing to opt out of the Settlement exceeds 335,000 shares at that time,
Defendants may elect to terminate and cancel this Stipulation at their sole
option by giving written notice to Plaintiffs' Co-Lead Counsel within (5) five
business days after receipt of this information from Plaintiffs' Co-Lead
Counsel.

                  b. WITHDRAWAL OF OPT-OUTS

                  If Plaintiffs' Co-Lead Counsel succeed in causing the
withdrawal of a certain number of opt-outs before the Settlement Hearing
commences so that the number of shares electing to opt-out equals or falls below
335,000 shares, then any notice of election to withdraw pursuant to subparagraph
(a), above, shall be a nullity. The filing of such withdrawal of opt-outs may be
done by Plaintiffs' Co-Lead Counsel;

                  c. TERMINATION DUE TO EXCLUSION AT HEARING

                  If the number of shares that have timely elected to opt-out
(and have not been withdrawn) combined with the number of shares excluded by the
Court at the Settlement Hearing exceeds 335,000 shares Defendants may elect to
terminate and cancel this Stipulation at their sole option within (3) three
business days after the Settlement Hearing. In the event the Court reserves its
decision regarding the exclusion of persons from the Settlement Class, the
Defendants' right to terminate and cancel this Stipulation pursuant to this
paragraph shall be preserved until such time as the Court renders its decision,
in which case the Defendants may elect to exercise their right to terminate and
cancel this Stipulation, at their sole option, by giving written notice to
Plaintiffs' Co-Lead Counsel within (3) three business days following receipt of
the Court's decision.

         K. MISCELLANEOUS PROVISIONS.

         1. All of the exhibits attached hereto are incorporated by this
reference and made a part hereof as though fully set forth herein.

<PAGE>   22

         2. This Stipulation, including this paragraph, may be amended or
modified only by a written instrument signed by all undersigned parties or their
successors-in-interest and approved by the Court.

         3. The waiver by one party of any breach of this Stipulation by any
other party shall not be deemed a waiver of any other, prior or subsequent
breach of this Stipulation.

         4. This Stipulation and its exhibits and the separate escrow agreement
constitute the entire agreement among the undersigned parties and no
representations, warranties or inducements have been made to any party
concerning this Stipulation or its exhibits, or the settlement it contemplates,
other than the representations, warranties and covenants contained and
memorialized in this Stipulation and its exhibits and the separate escrow
agreement. In entering into this Stipulation, each member of the Settlement
Class specifically waives and forever releases any and all claims, known or
unknown, whatsoever based on federal, state, local, statutory, or common law or
any other law, rule or regulation related to the execution of, and entry into,
this Stipulation, including, but not limited to, claims for fraud in the
inducement, negligent misrepresentation or fraud.

         5. This Stipulation, the settlement described herein, and the
consideration therefore are offered and given in return for and are contingent
upon the releases of the Released Claims described herein, the payment of the
Class Settlement Fund by or on behalf of Defendant, and Defendant receiving a
full and final dismissal on the merits and with prejudice under Rule 54 of the
Federal Rules of Civil Procedure or otherwise, and without costs and attorneys'

         6. Any allowance, disallowance, or modification of the following shall
not constitute grounds for the termination, cancellation or voiding of this
Stipulation and settlement, and shall not affect the effectiveness of this
Stipulation:

                  a. any denial or partial denial of applications, motions,
appeals or other proceedings of any kind and nature whatsoever which relate in

Litigation by the Plaintiffs' Counsel; or

distribution of the Net Settlement Amount to Authorized Claimants.

         7. In the event that the Effective Date does not occur, then, within

to the Escrow Agent and counsel for all other undersigned parties, the stock and
warrants issued and payment made by or on behalf of Defendants to the Class
Settlement Fund shall be refunded by the Escrow Agent to Defendants, plus any
proceeds realized from the sale of Celeris Corp. common stock and all interest
earned thereon. Any reasonable and necessary amounts actually incurred in
connection with the Costs of Notice and Settlement Administration will not be
refunded to Defendants, up to a maximum of $50,000. In such event, the
undersigned parties shall be deemed to have reverted to their respective
statuses as of the date and time immediately prior to the execution of this
Stipulation, and they shall proceed in all respects as if this Stipulation, its
exhibits, and any related agreements or orders had never been executed, provided
that the portion of the Class Settlement Fund that is not refunded pursuant to
this Paragraph shall be credited against such recovery, if any, whether by
settlement or judgment, which may eventually be obtained from Defendants. In
such event, the undersigned parties jointly will seek vacation of any order
entered or actions taken in connection herewith.

affiliates, officers and directors of Summit, the heirs and members of the
immediate families of the individual defendants, the legal representatives,
heirs, successors and assigns of any defendant, and any entity in which any
defendant has or had a controlling interest.

         3. For purposes of the Proposed Settlement only, the law firms of
Lockridge Grindal Nauen P.L.L.P., 100 Washington Avenue South, Suite 2200,
Minneapolis, Minnesota 55401, Pomerantz Haudek Block & Grossman, 26th Floor, 100
Park Avenue, New York, N.Y., 10017 and Morris and Morris, Suite 1600, 1105 North

Co-Lead Counsel for Plaintiffs to act on behalf of the Settlement Class,
including the Named Plaintiffs, and the other Plaintiffs' counsel, with respect
to all acts or consents permitted or required by the Stipulation, or such other
acts as may be reasonably necessary to consummate the Proposed Settlement.

         4. Having reviewed the proposed form of Notice of Pendency of Class
Action, Conditional Class Certification, Settlement and Fairness Hearing
submitted by the parties as Exhibit C to the Stipulation ("Notice of Settlement
Hearing") and the Plan of Allocation contained therein, the Court hereby
approves such Notice of Settlement Hearing and directs that Co-Lead Counsel for
Plaintiffs shall mail, or cause to be mailed, such Notice of Settlement Hearing
to all members of the Settlement Class ("Settlement Class Member" or "Settlement
Class Members") who can be identified through reasonable effort. The mailing is
to be made by first class United States mail, postage prepaid no later than 10
days after the date of this Order and at least 45 days prior to the date of

         5. Having reviewed the proposed form of Summary Notice of Pendency of
Class Action, Conditional Class Certification, Settlement and Fairness Hearing
submitted by the parties as Exhibit D to the Stipulation ("Summary Notice"), the
Court hereby approves such Summary Notice and directs that Co-Lead Counsel for
Plaintiffs shall cause such Summary Notice to be published once in the Monday
Legal Section of USA Today and in the Business Section of the Minneapolis Star
Tribune no later than 20 days after entry of the Order of Preliminary Approval
by the Court.

         6. The Court finds and determines that mailing of the Notice of
Settlement Hearing and publication of the Summary Notice in the USA Today and
Star Tribune newspapers constitute the best notice to the Settlement Class
practicable under the circumstances, constitute due and sufficient notice of the
matters set forth in said Notices, to all persons entitled to receive notice,
and duly satisfy the requirements of due process and of Rule 23 of the Federal
Rules of Civil Procedure.

         7. A hearing will be held by this Court in Courtroom 15E, United States
District Court, District of Minnesota, U.S. Courthouse, 300 South Fourth Street,
Minneapolis, Minnesota 55415 at 9:00 a.m. on January 5, 2001 (the "Settlement
Hearing"), to determine (a) whether the proposed class should be finally
certified; (b) whether the Proposed Settlement should be approved as fair,
reasonable, adequate and in the best interests of the Settlement Class; (c)
whether a final judgment dismissing the Litigation on the merits, with prejudice
and without costs, should be entered against Settlement Class Members and in
favor of Defendants as required by the Stipulation; (d) whether the proposed
allocation and distribution of the Net Settlement Amount is fair; and (e)
whether Counsel for Plaintiffs' petition for an award of attorneys' fees,
experts' fees, costs and expenses (the "Fee Petition") should be approved. The
hearing will also consider whether the proposed class should be finally
certified under Federal Rules of Civil Procedure 23(a) and 23(b)(3). The
Settlement Hearing is subject to continuation or adjournment by the Court
without further notice to the Settlement Class members.

         9. No person shall be entitled to object to the Proposed Settlement, to
the final judgment to be entered in the Litigation, to the allocation of the
settlement proceeds, or to any award of attorneys' fees, costs and expenses to
Plaintiffs' Counsel, or otherwise to be heard, except by serving and filing a

         12. Upon the entry of the Order for Final Judgment in form and
substance substantially identical to the order submitted by the parties as
Exhibit B to the Stipulation, after the Settlement Hearing, all Settlement Class
Members, whether or not they have filed a Proof of Claim within the time
provided, shall be permanently barred and enjoined from commencing, instituting,
or prosecuting

                                       5
<PAGE>   33

any action or other proceeding or asserting any claims constituting or arising
from Released Claims against Defendant in any court of law or equity,
arbitration tribunal or administrative or other forum, and that all Settlement
Class Members conclusively shall otherwise be bound by all of the terms of this
Stipulation, including without limitation, the terms of any judgment entered,

         13. The Stipulation of Settlement, and any and all exhibits or
documents referred to therein, and terms, conditions or representations therein,
or any action taken to carry out this Stipulation or this Settlement, may not be
construed as or used as an admission by or against Defendants of any fault,
wrongdoing or liability whatsoever. Defendants have denied and expressly
continue to deny all of Plaintiffs' claims. Pursuant to Federal Rule of Evidence
408, the Rules of Evidence of the various states and the Rules of Evidence
followed by any quasi-judicial bodies, including regulatory and self-regulatory
organizations, the fact of entering into or carrying out the Stipulation, the
exhibits hereto, and any negotiations and proceedings related hereto, shall not
be construed as, offered into evidence as, or deemed to be evidence of, an
admission or concession of liability by or an estoppel against any of the
parties, and shall not be offered or received into evidence, or considered, in
any action or proceeding against any party to the Litigation in any judicial,
quasi-judicial, administrative agency, regulatory or self--regulatory
organization, or other tribunal, or proceeding for any purpose whatsoever, other
than to enforce the provisions of this Stipulation or the provisions of any
related agreement, release, or exhibit hereto, or in the case of any subsequent
action against Defendants, Named Plaintiffs and any Plaintiffs' Counsel or the
Class on any or all of the Released Claims, in order to support a defense of res
judicata, collateral estoppel, accord and satisfaction, release or other theory
of claim or issue preclusion or similar defense.

         14. Upon the entry of the Order for Final Judgment after the Settlement
Hearing, and upon the Effective Date of the final judgment, which will occur on
the date upon which the judgment in the Litigation becomes not subject to
further appeal or review, only persons who are Authorized

                                       6
<PAGE>   34

Claimants shall have rights in the distribution of the Net Class Settlement Fund
created by the Proposed Settlement.

         15. Pending final determination of whether the settlement contained in
the Stipulation shall be approved, neither the Named Plaintiffs nor any other
Settlement Class Member, either directly, representatively or in any other
capacity, shall continue, commence or prosecute the Litigation.

         16. The capitalized terms used herein shall have the meaning assigned
to them in the Stipulation.

         WHEREAS, on _____________, 2000, at ________ __.m., at the United

Litigation.

         2. The form, content and method of dissemination of the notice given to

the circumstances.

         3. The notice, as given, complied with the requirements of Rule 23 of
the Federal Rules of Civil Procedure, satisfied the requirements of due process
and constituted due and sufficient notice of the matters set forth therein.

         4. The Settlement set forth in the Stipulation is fair, reasonable,

                                       2
<PAGE>   37

         6. The Named Plaintiffs and the Settlement Class Members, and all and
each of them, are hereby bound by the terms of the Settlement set forth in the
Stipulation.

         7. The provisions of the Stipulation, including definitions of the
terms used therein, are hereby incorporated by reference as though fully set
forth herein. The meaning of the terms used herein shall have the meaning
assigned to them in the Stipulation.

         NOW, THEREFORE, IT IS HEREBY ORDERED AS FOLLOWS:

         1. The Litigation should proceed as a class action pursuant to Rules
23(a) and 23(b)(3) of the Federal Rules of Civil Procedure and the following
Settlement Class is certified: all persons or entities who purchased or acquired
shares of Summit during the period August 4, 1995 through March 3, 1997,
inclusive on behalf of themselves and their heirs, executors, administrators,
beneficiaries, predecessors, successors, assigns, and any of their former and
present employees, directors, officers, accountants, agents, attorneys,
representatives, affiliates and subsidiaries. Excluded from the Settlement Class
are the Defendants, subsidiaries, affiliates, officers and directors of Summit,
the heirs and members of the immediate families of the individual defendants,
the legal representatives, heirs, successors and assigns of any defendant, and
any entity in which any defendant has or had a controlling interest.

         2. The Settlement set forth in the Stipulation is fair, reasonable,
adequate and in the best interests of the Settlement Class, and it shall be
consummated in accordance with the terms and provisions of the Stipulation.

         3. Judgment shall be, and hereby is, entered dismissing the Litigation
with prejudice, on the merits against Defendants, not including Ernst & Young
LLP, and without costs to any party as against any other.

         4. From and after the Effective Date, the Named Plaintiffs and all
members of the Settlement Class (except for those persons who properly excluded
themselves from the Class and whose names appear on Exhibit 1) on behalf of
themselves and their heirs, executors, administrators,

                                       3
<PAGE>   38

beneficiaries, predecessors, successors, assigns and each of them, and any of
their former and present employees, directors, officers, accountants, agents,
attorneys, representatives, affiliates and subsidiaries have released any and
all claims which the Settlement Class Members, or any of them, had or have
against Defendants, arising out of, based upon, or otherwise related to, the
Released Claims, whether in litigation, arbitration, or any other forum.

         5. The Stipulation of Settlement, and any and all exhibits or documents
referred to therein, or any terms, conditions or representations therein, or any
action taken to carry out the Stipulation or this Settlement, may not be
construed as or used as an admission by or against the Defendants of any fault,
wrongdoing or liability whatsoever. Pursuant to Federal Rule of Evidence 408,
the Rules of Evidence of the various states and the Rules of Evidence followed
by any quasi-judicial bodies, including regulatory and self-regulatory
organizations, the fact of entering into or carrying out the Stipulation, the
exhibits hereto, and any negotiations and proceedings related hereto, shall not
be construed as, offered into evidence as, or deemed to be evidence of, an
admission or concession of liability by or an estoppel against any of the
parties. Likewise, such acts shall not be offered or received into evidence, or
considered, in any action or proceeding against any party to the Litigation in
any judicial, quasijudicial, administrative agency, regulatory or
self-regulatory organization, or other tribunal, or proceeding for any purpose
whatsoever, other than to enforce the provisions of this Stipulation or the
provisions of any related agreement, release, or exhibit hereto, or in the case
of any subsequent action against the Defendants, Named Plaintiffs, and
Plaintiffs' Counsel, or the Class on any or all of the Released Claims, in order
to support a defense of res judicata, collateral estoppel, accord and
satisfaction, release or other theory of claim or issue preclusion or similar
defense.

         6. Each Settlement Class Member, on behalf of themselves and their
heirs, executors, administrators, beneficiaries, predecessors, successors,
assigns and any of their former and present employees, directors, officers,
accountants, agents, attorneys, representatives, affiliates and

                                       4
<PAGE>   39

subsidiaries, releases and forever discharges any and all manner of actions,
causes of action, suits, obligations, claims, debts, demands, agreements,
promises, liabilities, controversies, costs, expenses, and attorneys' fees
whatsoever, whether in law or equity and whether based on federal law, state
law, common law, or foreign law, right of action or otherwise, foreseen or
unforeseen, matured or unmatured, known or unknown, accrued or not accrued,
which they or any of them, either individually or as a Settlement Class Member,
ever had, now have, or can have, or shall or may hereafter have against
Defendants (as defined in Paragraph V.A.4) or any of them, for, based on, by
reason of or arising from or in any way relating to the Released Claims. Each
Settling Class Member releases and forever discharges Defendants whether or not
such Settling Class Member executes and delivers the Proof of Claim and Release.

         7. The Settlement Class Members shall be forever barred and enjoined
from commencing, instituting or prosecuting any action or other proceeding in
any court of law or equity, arbitration tribunal or administrative forum,
directly, representatively or derivatively, that asserts against Defendants any
claims that relate to or constitute any of the Released Claims.

         8. All Persons shall be barred and permanently enjoined from
initiating, asserting or prosecuting any and all future claims for contribution
arising out of or relating to the overstatement of revenues that gave rise to
the underlying action.

         9. All Persons or entities whose names appear on Exhibit 1, which is
attached and incorporated, who have duly and timely requested exclusion from the
Settlement Class are excluded from the Settlement Class, not bound by this Order
and Final Judgment, and may not under the circumstances make any claim or
receive any benefit from the Settlement. Each Settlement Class Member not
appearing on Exhibit 1 is bound by this Order and Final Judgment, and will
remain forever bound, regardless of whether such member ever files a Proof of
Claim and Release.

         10. Plaintiffs' Co-Lead Counsel and counsel for the plaintiffs are
hereby awarded ________________________ from the Class Settlement Fund with
interest, as reasonable attorneys'

                                       5
<PAGE>   40

fees, expert fees, costs, and expenses which shall be paid from the Class
Settlement Fund to Plaintiffs' Co-Lead Counsel for Plaintiffs' Co-Lead Counsel
to allocate among plaintiffs' counsel, which amount shall bear interest until it
is paid at the same rate as that earned by the Settlement Fund.

         11. The Defendants and their counsel and agents shall have no
responsibility or liability whatsoever with respect to and no person shall have
any claim against the Defendants and their counsel and agents with respect to
the investment or disbursement of the Class Settlement Fund by the Escrow Agent,
or the determination, administration, calculation or payment of claims, or
withholding of taxes, or any losses incurred in connection therewith, or with
respect to any other matter relating to the processing of claims.

         12. The Court hereby retains and reserves jurisdiction over (a)
implementation of the Settlement and any distribution to Authorized Claimants
under the terms and conditions of the Stipulation and pursuant to further orders
of this Court; (b) disposition of the Class Settlement Fund, (c) the Litigation,
until (i) the Effective Date contemplated by paragraph V.A.5 of the Stipulation,
which will occur on the date upon which this judgment is no longer subject to
further appeal or review, and (ii) each and every act agreed to be performed by
the parties shall have been performed pursuant to the terms and conditions of
the Stipulation, including the exhibits annexed thereto: (d) the Litigation, for
the purpose of implementing distribution to shareholders in accordance with the
notice; and (e) all parties, for the purpose of enforcing and administering the
Stipulation and this Settlement.

         13. There is no just reason for delay in the entry of judgment pursuant
to Rule 54(b) of the Federal Rules of Civil Procedure, and the Clerk is hereby
directed to enter judgment in accordance with this Order and Final Judgment.

         14. Entry of final judgment and final approval of the Settlement
settles all claims that have been asserted or could have been asserted in this
Litigation.

                                       6
<PAGE>   41

         15. Certification under Rule 54(b) will not result in unnecessary
appellate review, nor will review of the adjudicated claims moot any further
developments in the Litigation. Even if appeals are subsequently filed, the
nature of these claims are such that the appellate Court would not have to
decide the same issue more than once. The reservation of jurisdiction by this
Court pursuant to paragraph 9 shall not affect in any way the finality of this
Order and Final Judgment.

         16. Any and all objections to the Settlement, the Plan of Allocation
and the application for attorneys' fees, expense fees, costs and expenses are
hereby denied.

         LET JUDGMENT BE ENTERED ACCORDINGLY.

                                          BY THE COURT:

TO:      ALL PERSONS WHO PURCHASED OR OTHERWISE ACQUIRED SHARES IN SUMMIT

                                  SPECIAL NOTE

THIS NOTICE MAY AFFECT YOUR RIGHTS. YOU ARE URGED TO READ IT CAREFULLY. PLEASE
NOTE THAT THOSE PERSONS WHO PURCHASED OR OTHERWISE ACQUIRED SUMMIT SHARES DURING
THE PERIOD AUGUST 4, 1995 THROUGH MARCH 3, 1997, INCLUSIVE, MAY BE SETTLEMENT

ACTION SETTLEMENT DESCRIBED IN THIS NOTICE.

                               SETTLEMENT SUMMARY

STATEMENT OF CLASS RECOVERY

         The proposed settlement creates a fund in the amount of $750,000 in
cash, 100,000 shares of Celeris Corp. common stock and 500,000 warrants in
Celeris Corp. common stock (the "Settlement Fund"). The total value of the
settlement is approximately $2,000,000 based on the Celeris Corp. stock price as
of September 14, 2000. Based on plaintiffs' counsel estimate of the number of
shares entitled to participate in the settlement, the average recovery per share
before deduction of any Court awarded attorneys' fees and expenses, would be
approximately $.30, depending on, among other things, the number of valid claims
submitted by Settlement Class

<PAGE>   43

Members, the actual prices paid for Summit common stock, and when such shares
were purchased and sold during the Class Period. The total value of the
settlement is based upon current market prices and there is a potential that
when the distribution is made, the actual recovery may be greater or less based
upon a change in the market value of the Celeris Corp. common stock.

         Defendants deny any liability to plaintiffs and, as a result, believe
there should be no damages. The parties also do not agree on the average amount
of damages per share that would be recoverable if plaintiffs were to have
prevailed on each claim asserted. The issues on which the parties disagree
include: (1) the appropriate economic model for determining the amount by which
Summit common stock was allegedly artificially inflated (if at all) during the
Class Period; (2) the amount by which Summit common stock was allegedly
artificially inflated (if at all) during the Class Period; (3) the effect of
various market forces influencing the trading price of Summit common stock at
various times during the Class Period; (4) the extent to which external factors,
such as general market conditions, influenced the trading price of Summit common
stock at various times during the Class Period; (5) the extent to which the
various matters that Plaintiffs alleged were materially false or misleading
influenced (if at all) the trading price of Summit common stock at various times
during the Class Period; (6) the extent to which the various allegedly adverse
material facts that Plaintiffs alleged were omitted influenced (if at all) the
trading price of Summit common stock at various times during the Class Period;
and (7) whether the statements made of facts allegedly omitted were false,
material or otherwise actionable under the federal securities laws.

STATEMENT OF ATTORNEYS' FEES AND COSTS SOUGHT

         Plaintiffs' Counsel intend to apply to the Court for an award of
attorneys' fees not to exceed 33-1/3% of the Settlement Fund plus expert fees
and other costs and expenses.

REASONS FOR SETTLEMENT

         Plaintiffs' Counsel have carefully weighed the benefits to the
Settlement Class of the settlement of the Litigation for the consideration
offered by the Defendants against the significant costs, risks of recovery, and
delay that continued prosecution of the Litigation would involve. Plaintiffs'
Counsel recognize the expense and length of continued proceedings necessary to
continue the Litigation against the Defendants through trial and appeals and
have considered the problems of proof, and believe that the certainty and amount
of this recovery outweigh the risks of proceeding further with the Litigation.
The Defendants, while denying any wrongdoing or liability relating to matters
alleged, have concluded that further conduct of the Litigation would be unduly
expensive, burdensome and protracted. They have devoted, and unless this
settlement is finalized, will continue to devote substantial amounts of time,
energy and resources to the defense of the claims asserted by the Named
Plaintiffs in the Litigation. The Defendants have determined that it is in their
best interests to settle the Litigation in the manner and upon the terms and
conditions set forth in this Stipulation to eliminate the burden and the expense
of further protracted litigation.

Civil Procedure and pursuant to an Order of the United States District Court for
the District of Minnesota (the "Court") entered on October 4, 2000, in the

common stock and 500,000 Celeris warrants has been reached in the Litigation and
preliminarily approved by the Court. The total settlement value is approximately

The purpose of this Notice is to advise you of this proposed settlement, the
terms of which are summarized herein and are fully contained in documents filed
with the Court and which are available for your inspection at the offices of the
Clerk of Court for the United States District Court for the District of

BY THE TERMS OF THE PROPOSED SETTLEMENT AND BY THE FINAL JUDGMENT AND ORDER OF
DISMISSAL CONTEMPLATED THEREUNDER EVEN IF YOU FAIL TO SUBMIT A PROOF OF CLAIM
AND RELEASE FORM. ALL CLAIMS WILL BE DEEMED RELEASED UNLESS YOU SEEK EXCLUSION
IN ACCORDANCE WITH PARAGRAPH 3 OF THIS NOTICE. CERTAIN PROVISIONS OF THE
PROPOSED SETTLEMENT ARE DESCRIBED 1N THIS NOTICE, BUT THE DOCUMENTS ON FILE WITH

                  BACKGROUND AND DESCRIPTION OF THE LITIGATION

         Plaintiffs commenced this class action pursuant to Section 10(b) and
20(a) of the Securities Exchange Act of 1934, and Sections 11 and 15 of the
Securities Act of 1933 on behalf of a class of persons who purchased or
otherwise acquired shares of Summit Medical Systems, Inc. stock between August
4, 1995, the date of Summit's initial public offering, and March 3, 1997, the
date Summit announced that its financial statements had overstated its revenues
since 1994. The original defendants were Summit and certain individual officers
and directors of Summit and Ernst & Young, the accounting firm which served as
an "expert" in connection with Summit's IPO. The Teachers' Retirement System of
Louisiana brought an individual action against Summit and the same individual
defendants. Ernst & Young was dismissed as a defendant in this action and a
separate suit was later commenced against them. The remaining parties in this
action and the Teachers' Retirement System of Louisiana have now reached a
settlement. Defendants deny all allegations that they violated the securities
laws.

                            STIPULATION OF SETTLEMENT

         1. All of the parties to the Litigation have entered into a Stipulation
of Settlement (the "Stipulation"), which has been preliminarily approved by the
Court. The Stipulation fully sets forth the terms of the proposed settlement of
the Litigation and is available for inspection as herein provided. Certain terms
are defined in the Stipulation, and if used in this Notice have the meaning
assigned to them in the Stipulation.

         THE COURT HAS NOT DECIDED ANY OF THE SUBSTANTIVE CONTENTIONS OF THE
PARTIES, AS PLED BY THE COMPLAINT, AND, THEREFORE, NO INFERENCES REGARDING THE
MERITS OF THE LITIGATION SHOULD BE DRAWN FROM THE SENDING OF THIS NOTICE. THE
GIVING OF THIS NOTICE IS NOT MEANT TO IMPLY THAT THERE HAVE BEEN ANY VIOLATIONS
OF THE LAW OR THAT RECOVERY AFTER TRIAL COULD OR COULD NOT BE HAD IF THE
LITIGATION HAD NOT SETTLED.

                      CLASS ACTION DETERMINATION; EXCLUSION

         2. Pursuant to the Court's Order Preliminarily Approving Settlement
dated October 4, 2000, the Court certified a Settlement Class of all persons or
entities who purchased or otherwise acquired shares of Summit during the period
August 4, 1995 through March 3, 1997, inclusive on behalf of themselves and
their heirs, executors, administrators, beneficiaries, predecessors, successors,
assigns, and any of their former and present employees, directors, officers,
accountants, agents, attorneys, representatives, affiliates and subsidiaries.
Excluded from the Settlement Class are the Defendants, subsidiaries, affiliates,
officers and directors of Summit, the heirs and members of the immediate
families of the individual defendants, the legal representatives, heirs,
successors and assigns of any defendant, and any entity in which any defendant
has or had a controlling interest.

written request for exclusion on or before December 22, 2000, with the Clerk of
the United States District Court for the District of Minnesota, by mail

IN RE SUMMIT MEDICAL SYSTEMS, INC. SECURITIES LITIGATION, Civ. No. 97-558
JMR/FLN, and must include a statement that such Settlement Class Member wishes

exclusion also must provide the quantity (I.E., the number of shares) of Summit
purchased, the dates of such purchases, the price paid or consideration given
for the shares purchased, the dates such shares were sold, and the amount of the
proceeds of such sale. If you submit a timely request for exclusion as specified
in this paragraph, you will not be bound by the settlement as set forth in the
Stipulation and described in this Notice, and will not be entitled to receive
any proceeds from the settlement or to participate in any other benefits of the
settlement. Copies of such requests for exclusion must also be served by first
class mail or by hand on and received by the following counsel on or before the

                       SUMMARY OF THE PROPOSED SETTLEMENT

         5. The proposed settlement calls for a Class Settlement Fund to be
created consisting of a payment in the sum of $750,000 in cash, 100,000 shares
of Celeris Corp. common stock and 500,000 warrants for Celeris Corp. stock with
an exercise price of $4.00 per share and an expiration date of September, 1
2005. The total value of the Class Settlement Fund is approximately $2,000,000
based on Celeris Corp. stock price as of September 14, 2000. The Class
Settlement Fund, including interest earned thereon, will be distributed to
Settlement Class Members after a deduction of such amounts as are awarded by the
Court to Plaintiffs' counsel for attorneys' fees, experts' fees, costs and
expenses ("Net Settlement Fund"). It is anticipated that some or all of the
Celeris Corp. common stock will be sold prior to distribution to Settlement
Class Members. The

                                       8
<PAGE>   50

proceeds from such stock sales will be included in the money distributed to the
Settlement Class Members. At this time, it is anticipated that the average per
share recovery is approximately $.30.

         6. Each Settlement Class Member who submits a Proof of Claim and
Release Form ("Claimant") will be awarded a pro rata share of the Net Settlement
Fund which will be determined by the ratio that each Authorized Claimant's loss
bears to the recognized losses of all other Authorized Claimants. If a member of
the Settlement Class sold its, his or her Summit shares at a price higher than
its, his or her purchase price for such shares, there is no Recognized Loss and
in such event the member of the Settlement Class is not entitled to receive any
proceeds of the Class Settlement Fund with respect to such transactions.

         7. The proposed settlement contains the following release terms:

            Each Settlement Class Member, on behalf of themselves and their
            heirs, executors, administrators, beneficiaries, predecessors,
            successors, assigns, and any of their former and present employees,
            directors, officers, accountants, agents, attorneys,
            representatives, affiliates and subsidiaries, releases and forever
            discharges any and all manner of actions, causes of action, suits,
            obligations, claims, debts, demands, agreements, promises,
            liabilities, controversies, costs, expenses, and attorneys' fees
            whatsoever, whether in law or in equity and whether based on federal
            law, state law, common law, or foreign law right of action or
            otherwise, foreseen or unforeseen, matured or unmatured, known or
            unknown, accrued or not accrued, which they or any of them, either
            individually or as a Settlement Class Member, ever had, now have, or
            can have, or shall or may hereafter have against Defendants or any
            of them, for, based on, by reason of or arising from or in any way
            relating to the Released Claims.

            The Settlement Class Members shall be forever barred and enjoined
            from commencing, instituting or prosecuting any action or other
            proceeding in any court of law or equity, arbitration tribunal or
            administrative forum, directly, representatively or derivatively,
            that asserts against Defendants any claims that relate to or
            constitute any of the Released Claims.

            All persons shall be forever barred and permanently enjoined from
            instituting, asserting or prosecuting any and all future claims for
            contribution arising out of or relating to the overstatement of
            revenues that gave rise to the underlying litigation.

                                       9
<PAGE>   51

         8. The proposed settlement also requires the full and final dismissal
of the Litigation with prejudice and on the merits in favor of the Defendants
and against all Settlement Class Members, without costs to any party as against
any other, except as provided in the Stipulation.

         9. The proposed settlement is subject to the approval of the Court.
Further, the Named Plaintiffs and the Defendants may withdraw from the proposed
settlement under certain other circumstances described in the Stipulation in
which event the Stipulation will be terminated. If the Stipulation is
terminated, then the Class Settlement Fund will be returned to the Defendants.
Any reasonable and necessary amounts actually incurred in connection with the
Costs of Notice and Settlement Administration, up to a maximum of $50,000, will
not be refunded.

         10. If the Court does not approve the proposed settlement, or if the
proposed settlement or Stipulation is voided, terminated or canceled according
to its terms, then the parties and the Litigation shall revert to their
respective positions as of the date and time prior to the execution of the
Stipulation and the Litigation shall proceed in all respects as if no
Stipulation had occurred.

                         APPLICATION FOR ATTORNEYS FEES,
                        EXPERTS' FEES, COSTS AND EXPENSES

         11. Plaintiffs' Counsel will jointly apply to the Court for an award of
attorneys' fees not to exceed one-third of the Class Settlement Fund. In
addition, Plaintiffs' Counsel will seek reimbursement of experts' fees, costs
and expenses to be paid out of the Class Settlement Fund. The amounts to be
awarded to the Plaintiffs' Counsel, if any, will be decided by the Court.

                             THE SETTLEMENT HEARING

         12. A hearing will be held before the Honorable James M. Rosenbaum,
United States District Judge, in Courtroom 15E, United States District Court,
District of Minnesota, 300 South Fourth Street, Minneapolis, Minnesota 55415 on
January 5, 200, at 9:00 a.m. (the "Settlement Hearing") to determine: (a)
whether the proposed settlement should be approved as fair, reasonable, adequate
and in the best interests of the Settlement Class; (b) whether the Plan of
Allocation should

                                       10
<PAGE>   52

be approved; (c) whether a final judgment should be entered dismissing the
Litigation with prejudice as required by the Stipulation; and (d) disposition of
the Plaintiffs' Counsels' application for an award of attorneys' fees, experts'
fees, costs and expenses to be paid from the Class Settlement Fund.

         13. Although the issue of approval or disapproval of the settlement and
the application for an award of attorneys' fees, experts' fees, costs and
expenses may be decided at the same time, whether the proposed settlement is
approved and consummated will not depend upon whether an award of attorneys'
fees, experts' fees, costs and expenses is approved.

         14. The hearing on the proposed Settlement may be adjourned by the
Court from time to time, without further notice. The Court reserves the right to
act upon any or all of the matters set forth in Paragraph 13 without further
notice of any kind and to consider any other matter related to the proposed
settlement.

                                 RIGHT TO APPEAR

         15. At the Settlement Hearing, any member of the Settlement Class may
appear in person or by counsel and show cause, if any, why the proposed
settlement should not be approved as fair, reasonable, adequate and in the best
interests of the Settlement Class; why the proposed allocation of settlement
proceeds among Settlement Class Members should not be approved; why final
judgment should not be entered; or why the Court should not award the requested
attorneys' fees, experts' fees, costs and expenses to the Plaintiffs' Counsel.
However, no person will be heard at the Settlement Hearing unless the following
materials are served and filed by such person as described herein: (a) a notice
of intention to appear; (b) with respect to each transaction in Summit made by
such person during the Settlement Class Period, a statement setting forth the
date, type of transaction, price and amount of shares involved; (c) a detailed
statement of such person's specific objection to any matter before the Court,
the grounds therefor and the reasons for such person's desiring to appear and to
be heard; and (d) all documents and writings which such person desires the Court
to consider. Such materials must be FILED with and RECEIVED by the Clerk of
Court, United States District Court for the

                           PROOF OF CLAIM AND RELEASE

         NOTICE TO ALL PERSONS WHO PURCHASED OR OTHERWISE ACQUIRED SHARES IN
SUMMIT MEDICAL SYSTEMS, INC. SECURITIES LITIGATION ("SUMMIT") DURING THE PERIOD
AUGUST 4, 1995 THROUGH MARCH 3, 1997, INCLUSIVE: By Notice of Pendency of Class
Action, Settlement and Fairness Hearing (the "Notice"), enclosed with this Proof
of Claim and Release, you have been notified that, subject to approval by the
United States District Court for the District of Minnesota (the "Court"), the
above-described action (the "Litigation") has been settled, and that the
settlement, if approved by the Court, will result in a fund to be distributed to
authorized Settlement Class Members under the supervision of the Court.

         Only members of the Settlement Class who submit the attached Proof of
Claim and Release Form and who have an Allowed Claim (as described in the
Notice) are entitled to share in the Class Settlement Fund. You are not entitled
to share therein if you exercise the option set forth in the Notice to exclude
yourself from participation in the Settlement Class. You must have a Recognized
Loss in order to share in the distribution of net settlement proceeds. If you
have no loss, you will not be entitled to participate in the Class Settlement
Fund but will be bound by the terms of the settlement.

<PAGE>   59

         The Settlement Class consists of all persons or entities who purchased
or otherwise acquired shares of Summit Medical Systems, Inc. ("Summit") during
the period August 4, 1995 through March 3, 1997, inclusive, on behalf of
themselves and their heirs, executors, administrators, beneficiaries,
predecessors, successors, assigns, and any of their former and present
employees, directors, officers, accountants, agents, attorneys, representatives,
affiliates and subsidiaries ("the Settlement Class"). Excluded from the
Settlement Class are the Defendants, subsidiaries, affiliates, officers and
directors of Summit, the heirs and members of the immediate families of the
individual defendants, the legal representatives, heirs, successors and assigns
of any defendant, and any entity in which any defendant has or had a controlling
interest.

         If you think you are a member of the Settlement Class by virtue of the
purchase of Summit stock, you must submit the attached Proof of Claim and
Release Form to obtain a recovery in this Litigation.

         NOTICE TO BROKERS AND OTHER NOMINEES: If you purchased or acquired
Summit stock during the Settlement Class Period for another person or are acting
as administrator or executor for one who owned Summit stock purchased during the
Class Period, you are required to inform the beneficial owners of such stock, or
any heirs or other persons who might assert a claim for losses sustained on such
stock, of their right to file a Proof of Claim. You may obtain additional copies
of this Proof of Claim and Release Form from: Claims Administrator, Summit
Medical Litigation, P.O. Box 2370, Minneapolis, Minnesota 55402-0370.
Plaintiffs' Co-Lead Counsel shall reimburse you for reasonable expenses incurred
by the nominee either in mailing copies of this Notice directly or in
identifying beneficial owners.

                         INSTRUCTIONS ON MAKING A CLAIM:

TO RECEIVE ANY PAYMENTS FROM THIS SETTLEMENT, YOU MUST SIGN THIS PROOF OF CLAIM
AND RELEASE FORM.

         1. Distribution of the proceeds of the settlement is subject to court
approval.

         2. This Proof of Claim and Release Form must be received on or before

                     Claims Administrator
                     Summit Medical Litigation
                     P.O. Box 2370
                     Minneapolis, Minnesota 55402-0370

         3. Neither the Clerk of Court, Named Plaintiffs or Plaintiffs' Counsel
will be responsible if your Proof of Claim and Release Form is not timely

protect your claim, though it is not required.

         4. The Proof of Claim must be filed in the name or names of the actual
beneficial owner or owners of the stock upon which the claim is based. All joint
owners must sign the Proof of Claim and Release Form. Executors, administrators,
guardians and trustees may complete and sign the form on behalf of the persons
represented by them, but must identify the beneficial owners. Proof of their
authority need not accompany the Proof of Claim and Release Form, but their
titles or capacities must be stated.

         5. Your Proof of Claim and Release Form must be signed.

         6. Do not submit more than one Proof of Claim and Release Form for all
of your claims. Do not submit any duplicate claims. If, subsequent to filing a
claim, you discover additional claims or documentation, write to the address
given above, identify your original claim, and ask that it be supplemented.

         7. You will recover a pro rata amount of your losses based upon the
total losses ("Recognized Loss") sustained by all members of the Settlement
Class. You need not compute your

                                       3

Recognized Loss. If a member of the Settlement Class sold Summit shares at a
price higher than the purchase price for such shares, there is no Recognized
Loss and in such event that member of the Settlement Class is not entitled to
receive any proceeds of the Class Settlement Fund with respect to such
transactions.

(C) the Employee engages in conduct that constitutes neglect or willful
misconduct in carrying out his duties under this Agreement; (D) material breach
of this Agreement by the Employee; or (E) the Employee's breach of fiduciary
duty to the Employer. The Employee shall have 30 days to address the Employer
Board and to effect a cure if possible for any alleged breach of duty.

         In the event of termination of the Employee's employment by the
Employer for Cause, the Employee shall only be entitled to:

                  (i)      any accrued but unpaid base salary through his date
of termination;

                  (ii)     any earned but unpaid bonus from a prior fiscal year;

                  (iii)    reimbursement of reasonable business expenses
incurred prior to the date of termination; and

                  (iv)     other or additional benefits, if any, in accordance
with the applicable employee benefit programs of the Employer referred to in
Section 5.

         (b)      Death, Retirement or Disability. In the event of the death,

or the Employee's estate or legal representative, as appropriate, shall be
entitled to the amounts referred to in paragraph (a) of this Section.

                  For purposes of this Agreement:

                  (i)      "Disability" shall mean "total and permanent
disability", as defined in the Employer's long term disability plan for senior
executives (or such other Employer-provided long-term disability benefit plan
sponsored by the Employer in which Employee participates at the time the
determination of Disability is made) (the "Disability Plan"); provided, however,
that no termination of the employment of Employee for Disability shall become
effective (x) prior to the expiration of six (6) months after the date the
Employee first incurs the condition giving rise to the Disability or (y) while
the Employee is substantially performing the regular duties associated with his
employment hereunder.

                  (ii)     "Retirement" shall mean a voluntary decision by the
Employee to retire at any time after attaining age 60.

         (c)      Termination Without "Cause" or for "Good Reason" (as such term
is defined below). If the Employer should terminate the Employee's employment
for any reason (including a termination as a result of a Change of Control)
other than for Cause, or in the event the Employee terminates employment for
Good Reason or Employer gives notice of its intent not to renew this Agreement
under Section 2, then:

                  (i)      All unvested stock options shall become fully vested
and shall remain exercisable for the remainder of the stated term of such stock
options, regardless of whether the Employee continues to be employed by the
Employer.

                  (ii)     The Employee shall be entitled to: (A) the amounts
referred to in paragraph (a) of this Section; (B) continued participation in the
medical, dental, hospitalization and group life insurance coverage in which he
was participating on the date of the termination of his employment until the
earlier of the end of the twelve (12) month period following his termination of
employment and the date, or dates, he receives substantially similar coverage
and benefits under the plans and programs of a subsequent employer; and (C)
reimbursement for outplacement counseling in accordance with the Employer's
established policies.

                  (iii)    In the event of the termination of employment of the
Employee by the Employer without Cause (other than as a result of a Change of
Control) or by the Employee for Good Reason (other than resignation following a
Change of Control), then the Employer shall pay the Employee, in a lump sum
within ten (10) days following such termination of employment, an amount equal
to 300% of the sum of his base salary plus an amount equal to the greater of the
annual bonus Employee received for performance during the Employer's immediately
preceding fiscal year or the current annual bonus target in effect at the time
of such termination or resignation.

<PAGE>   3

                  (iv)     In the event of the termination of employment of the
Employee by the Employer following a Change of Control as set forth in paragraph
(f) of this Section or resignation by the Employee within the ninety (90) day
period following a Change of Control pursuant to paragraph (e) of this Section,
then:

                           (A)      The Employer shall pay to the Employee in a
lump sum upon such termination or resignation an amount equal to 150% of the sum
of his base salary plus an amount equal to the greater of the annual bonus
Employee received for performance during the Employer's immediately preceding
fiscal year or the current annual bonus target in effect at the time of such
termination or resignation.

                           (B)      The Employer shall pay to Employee upon such
termination or resignation, as a retention bonus for services actually rendered
on and after the date of the Change in Control, a lump sum payment equal to 50%
of the sum of his base salary and the greater of the most recent annual bonus
paid or earned by Employee or the current annual bonus target in effect at the
time of such termination or resignation.

                           (C)      The Employer shall pay to Employee upon such
termination or resignation, in exchange for Employee agreeing not to solicit any
of the then current customers or employees of the Employer for a period of
twelve (12) months following his termination or resignation of employment, a
lump sum payment equal to 100% of the sum of his base salary and the greater of
the most recent annual bonus paid or earned by Employee or the current annual
bonus target in effect at the time of such termination or resignation.

         Employee must reasonably give thirty (30) days prior written notice of
his intent to terminate employment for Good Reason which notice sets forth in
detail the event or circumstances believed to constitute Good Reason. Upon
receipt of such notice, the Employer shall have twenty (20) days to cure its
conduct, to the extent such cure is possible.

         For purposes of this Agreement, "Good Reason" shall mean any of the
following: (AA) reduction in the amount of the Employee's then current base
salary (other than as part of a reduction affecting all of the 5 most senior
management employees of the Employer and its subsidiaries); (BB) any material
diminution in the employee's duties or responsibilities; or (CC) any material
breach by the Employer of any provision of this Agreement.

         (d)      Termination Without Good Reason. In the event of a termination
of employment by the Employee without Good Reason (other than a termination due
to death, Retirement or Disability), the Employee shall have the same
entitlements as provided in paragraph (a) of this Section for termination for
Cause.

         (e)      If the Employee resigns from employment for any reason, other
than Retirement or Disability, during the 90-day period following a Change of
Control, such resignation shall be deemed to be a termination by the Employee
for Good Reason for purposes of Section 7(c).

<PAGE>   4

         (f)      Termination shall be deemed to be a result of a Change of
Control: (i) if such termination occurs within twelve (12) months following the
Change of Control; or (ii) if any change in the Employee's title, reporting
relationship, responsibilities or authority as in effect immediately prior to
any Change of Control is made within twelve (12) months of such Change of
Control and which adversely affects to a material degree his role in the
management of the Employer; or (iii) if any reduction in the Employee's salary
paid to him by the Employer as in effect immediately prior to any Change of
Control or, if such salary has been subsequently increased at any time or from
time to time; any reduction in such increased salary; or (iv) if any termination
of the Employee's employee benefit programs, including, but not limited to, any
stock option plan, investment plan, savings plan, incentive compensation plan or
life insurance, medical plans or disability plans provided by the Employer to
the Employee and in which the Employee is participating or under which the
Employee is covered, all as in effect immediately prior to any Change of
Control; or (v) if there is any requirement by the Employer that the Employee's
position and principal office be based and located more than twenty (20) miles
outside the boundaries of the principal office of the Employee immediately prior
to the Change of Control; or (vi) if any failure or refusal of the Employer to
renew this Agreement under Section 2 after any Change of Control shall have
occurred.

         (g)      In the event of the termination of employment of the Employee
by the Employer without Cause or by the Employee for Good Reason or resignation
following a Change of Control, if the Employee is required, pursuant to Section
4999 of the Internal Revenue Code of 1986, as amended (the "Code"), to pay
(through withholding or otherwise) an excise tax on "excess parachute payments"
(as defined in Section 280G of the Code), the Employer shall pay the Employee
the amount necessary to place the Employee in the same after-tax financial
position that he would have been in if he had not incurred any excise tax
liability under Section 4999 of the Code.
