2.   ON THE CREDITORS

     2.1 Definition of the Creditors. For the purposes of this agreement, the
creditors are the natural juridical, Chilean or foreign persons who have
direct or indirect credits of any kind or amount applied. For the purposes of
clarifying this agreement, the creditors are divided as follows:

     (a) Financial Creditors: Those whose credits are originated in one or more
financial operations, whether commercial or investment banks, or national or
foreign financial institutions, investment companies or their assignees, or in
personal guarantees granted by Chilesat, and that are specified in the list
attached to number 7 of the First Petition of the brief recorded on page 1 of
these proceedings (hereinafter, all of them "Financial Creditors"). The
financial credits of these Financial Creditors, as defined below, are
hereinafter denominated "Financial Credits of Chilesat".

     (b) Suppliers: Those whose credits consist of the balance of the price of
purchase-sale agreements of assets, leasing with or without purchase option,
remunerations for rendering services, and, in general, any other creditor that
does not have the nature of a financial creditor.

     2.2  Creditors affected and committed by this agreement:

          2.2.1 Any common creditors without any exclusion, whether they attend
or not the Creditors' Meeting where this legal preventive agreement is settled,
whether they vote in favor or against the approval thereof, whether they are
included or not in the credit list attached to a petition of the brief
recorded on page 1 of these proceedings, with the right to vote, specifying
the name of the creditor, the amount of its credit, the nature of the
obligation and the total amount of the credits. Said list shall be timely
updated and the creditors that have been paid as a consequence of the normal
development of the commercial operations, including those that have acquired
credits during said period, shall be excluded.

          2.2.2 Preferential, mortgage, pledge, antichretic creditors, and
those who are entitled to the legal right of retention and which vote it,
whichever the amount, in accordance with the provisions in article 191 of the
Bankruptcy Law.

<PAGE>

          2.2.3 PREFERENTIAL CREDITORS: In accordance with the provisions of
article 191 in relation to article 180, both of Law No. 18,175 on Bankruptcy,
once this Agreement is approved it does not commit the preferential, mortgage,
pledge creditors or those who have the legal right of retention, provided that
they have not participated in the Agreement by exerting their vote and if they
have done it, only for the amount to which they have not waived their
privileges or guarantees. Therefore, the debtor shall continue meeting all the
obligations towards them in the form, terms and conditions duly set forth with
respect to each credit and, in the event of non-fulfillment, said creditors may
exert the guarantees that ensure their relevant credits according to the law,
until they obtain their total or partial payment, so that in the balance not
covered by the guarantee they shall be - in their nature as common creditors -
fully governed by the Agreement.

3.   OBJECT OF THE AGREEMENT

The Agreement proposed to Chilesat's creditors has the main purpose of
maintaining the company's line of business and thus overcoming its current
state of insolvency, which prevents it from developing its activities,
normally. Thus, the agreement aims at extending the maturity of the credits of
the Financial Creditors of Chilesat for a term of 120 running days counted
from the date on which these agreement proposals are favorably voted at the
Creditors' meeting summoned to decide on them.

     3.1  CREDIT EXTENSION FOR 120 RUNNING DAYS:

Chilesat's creditors are proposed to agree on an extension of the maturity of
the credits of the Financial Creditors of Chilesat for the term of 120 running
days counted from the date on which these proposals of the agreement are
favorably voted. During said 120-day term, the credits shall continue fully
valid and shall be subjected to the relevant conditions of non-moratory agreed
interest and/or adjustments. It is expressly evidenced that this extension
under no circumstance implies the novation of said credits.

Suppliers' credits and leasing agreements shall continue being paid under the
currently valid terms and, additionally, letter B shall not be applied thereto
("Extension and Form of Payment of Non Capitalized Credits).

Within the aforementioned 120 running days, the Financial Creditors who freely
and voluntarily thus decide it, shall be entitled to substitute their credits
under the terms indicated below:

     A.  NOVATION OF CREDITS AGAINST CHILESAT.
         ------------------------------------

The Financial Creditors of Chilesat who freely and voluntarily thus decide it,
may carry out a novation due to the change of debtor of their direct financial
credits against Chilesat, so that the new debtor of said credits will be its
home office Telex, and thus Chilesat is freed from the obligations related to
the substituted credits. Abstaining from carrying out the proposed novation
implies a rejection to this specific novation, and the obligations that had
been extended in accordance with clause 3.1 above shall be immediately due and
demandable.

The financial credits against Chilesat that are substituted, shall maintain
their own conditions and terms, as well as their guarantees, all of which
shall not be affected by the novation due to

<PAGE>

change of debtor. Once this novation is performed, the new obligation against
Telex shall be fully governed by the legal preventive agreement of the latter.
The proposals of the legal preventive agreement submitted by Telex permit the
creditors of said company, including the Financial Creditors of Chilesat who
freely and voluntarily thus decide it, to carry out a novation of their
credits due to change of debtor, in order to capitalize their credits in
Telex. The proposals of Telex's agreement have been submitted on this same
date with this court and they are at the disposal of the public for the
knowledge of the interested parties. In turn, they shall be voted at the
Creditors Meeting to be held before the creditors meeting of Chilesat.
Therefore, the creditors of the latter shall be fully informed about the terms
and conditions of said legal preventive agreement.

If after the credit novation the legal preventive agreement of Telex is
resolved by any cause whatsoever, the novation of the credits shall not be
affected. Thus, the Financial Creditors of Chilesat who have substituted their
credits and have thus become creditors of Telex, will remain in said position
and may not request the payment of same from Chilesat.

The novation due to change of debtor may be carried out only after the legal
preventive agreements of Telex and Chilesat have been legally approved by
executed resolution, and within the 120 running days mentioned above.

The novation due to change of debtor shall not be gratuitous, therefore, as a
consequence thereof, Telex shall be a creditor of Chilesat for an amount equal
to the amount in capital and interest of the novated credit.

This credit of Telex against Chilesat, originated in the novation due to
change of debtor, shall be compensated in an equal amount to the credits that
Chilesat has against Telex, and the unpaid balance for said compensation shall
be capitalized in Chilesat within the term of 270 running days counted from
the novation due to change of debtor. For these purposes, the shareholders of
Chilesat at a Special Shareholders' Meeting shall agree on a capital increase
for an amount that will make said capitalization possible.

If within the 120-day term mentioned above, no novation of credits has been
carried out due to change of debtor, representing at least 85% of all the
debts and direct financial obligations of Chilesat S.A with all its Financial
Creditors, as this term is defined in letter (a) number 2.1 of this agreement,
at the only exception of its indirect creditors, for which purpose
consideration shall be given to the direct credits recognized for said
Financial Creditors in the "Creditors' List" submitted by the Trustee of
Chilesat Mr. Jose Manual Edwards E. on November 19, 2001 in these proceedings
on the "Legal Preventive Agreement" of Chilesat S.A. handled in this same
court and which is considered fully reproduced in this part - hereinafter the
"Financial Credits of Chilesat" - and unless before the maturity date the
agreement has been modified in the way expressed in the following ninth
clause, these proposals for the modification of the agreement shall be totally
without effect, and the obligations that had been extended in accordance with
clause 3.1 above, shall be immediately due and demandable.

If this agreement becomes ineffective and the bankruptcy of Chilesat is
declared as indicated above, under no circumstance will the novations due to
change of debtor carried out by the creditors of Chilesat be affected, but
shall remain firm. Consequently, the creditors of Chilesat

<PAGE>

who have substituted their credits within the term of 120 running days
mentioned above, shall remain as creditors of Telex and shall be ruled at very
moment by the terms of the legal preventive agreement of said company. Said
creditors may not require from Chilesat the payment of the renewed credits.

     B.  EXTENSION AND FORM OF PAYMENT OF NON-RENEWED CREDITS.
         ----------------------------------------------------

If within the 120-day term mentioned above, the Financial Credits of Chilesat
representing at least 85% of the total thereof have been renewed in the
aforementioned manner, the Financial Credits of Chilesat shall not be renewed,
they shall be extended for a term of 15 days and paid in a single installment
at the end of said period. This novation shall be materialized within the term
of 120 running days and shall be evidenced with instruments that specify the
novation due to change of debtor, which shall be also attached by a
certificate issued by the firm Ernst & Young, external auditors of the debtor,
or by another firm of external auditors of recognized international prestige.

During said term, the amount of those Financial Credits of Chilesat, both in
capital and interest, shall not be subject to any adjustment, and shall accrue
no interest, commissions or surcharge of any type. During said term, the
Financial Credits of Chilesat thus extended shall not be demandable against
the debtor or against its bailors, sponsors, joint debtors - whether simple or
solidary - or against any guarantor, and no other real or personal guarantees
that might be backing those credits may be executed, and under no circumstance
shall they be the object of acceleration. These extended credits shall be paid
in a single installment at the end of the aforementioned term, in Chilean
pesos.

4.  EXPENSES

The expenses incurred as a consequence of the approval, execution and
fulfillment of this agreement shall be of the exclusive charge of Chilesat.

5.  INTERVENTION OF THE TRUSTEE

The Trustee mentioned in articles 176 and 199 of the Bankruptcy Law shall not
participate in this Agreement, and, consequently, the Debtor shall not be
subject to said intervention.

6.  DELIBERATION

In accordance with what has been said in the previous paragraphs, the debtor
and the creditors of Chilesat should express their opinion on these proposals
that modify the legal preventive agreement submitted by the debtor. If the
creditors of Chilesat and the debtor do not accept this modification and the
proposals of the agreement submitted by the latter are not approved, the judge
shall declare the bankruptcy of the debtor.

7.  VALIDITY

The Agreement shall be valid from the moment the legal resolution that
approves it is executed.

<PAGE>

In the event that the Agreement is not legally approved by a firm and executed
resolution, due to any reason, within the term of 30 running days counted from
the date of the Creditors' Meeting in which it is agreed, the agreements
adopted shall not be effective and the agreement shall be resolved. In this
case, the debtor's bankruptcy, whether by an official document of the court or
at the petition of the own debtor or any creditor, shall be immediately
declared.

Likewise, if within the same term of 30 running days mentioned in the previous
paragraph, the aforementioned Legal Preventive Agreement of Telex presented in
this same court by firm and executed resolution has not been legally approved,
the agreements adopted shall not be valid and the agreement shall be resolved.
In this case, the bankruptcy of the debtor, whether by an official document of
the court or at the petition of the own debtor or any creditor, shall be
immediately declared.

8.  LEGAL DOMICILE

For the purposes of this agreement, the parties establish their domicile in
the city of Santiago.

9.  MODIFICATION OF THIS AGREEMENT

At the proposal of the debtor or any creditor, this Agreement may be modified,
totally or partially, during its effective term. The modification shall be
considered accepted when it has the consent of the debtor and meets the
favorable votes of two thirds of the creditors governed by the Agreement, that
represent three fourths of the total liabilities, excluding only those
creditors specified in article 180 of Law No. 18,175. For these purposes,
after the proposal for modification is submitted to the Court that approved
the Agreement, this Court shall set forth: a) that the trustee designated,
inform the Court on the proposals of modification within the term of fifteen
days; b) that the creditors hold a meeting that may not take place before
thirty days have elapsed, to decide on the proposals of the modification; and
c) that the resolution that falls on the submission to the Trustee be notified
to the creditors through notice published in the Official Gazette. The same
creditors who had the right to vote at the meeting that settled the Agreement
that is to be modified, shall have the right to vote, without detriment that
in the case the credit has been assigned, the right to vote shall fall on the
relevant assignee. As regards everything else, the same rules that regulate
the agreement and the approval of the Legal Preventive Agreement shall govern,
as set forth in Law No. 18,175.

10.  ARBITRATION

Any doubt or difficulty related to the interpretation, fulfillment, execution,
validity or opposability of this Agreement, including the decision on the
validity of the arbitration clause or on the own arbitral competence, which
arises among two or more creditors or between any of them and the Debtor,
shall be solved each time by an arbitrator or referee, who shall act and
decide without form of judgment, consciously, and the parties hereby waive all
the resorts that might proceed against its resolutions.

For the exercise of the position, the parties first designate Mr. Raul Varela
Morgan, and if he rejects the position, due to negative or impossibility or
even due to a supervening cause arising during the exercise of the position,
they designate Mr. Enrique Barros Bourie in the second place and if he rejects
the position, due to negative or impossibility or even due to a supervening
cause arising

<PAGE>

during the exercise of the position, they designate Mr. Sergio Urrejola
Monckeberg in the third place.

If the aforementioned arbitrators are not available, the parties in conflict
shall designate the alternate arbitrator by mutual agreement. In the event no
agreement is reached, he will be appointed by the Judge who is sitting at the
Civil Courts of Santiago. In this case the appointment shall fall on a lawyer
who, at the date he accepts the position, is performing or has performed as
professor of the Civil Law or Commercial Law departments of the Law Faculties
of the Universidad de Chile or Universidad Catolica, with seat in Santiago.

Notwithstanding the above, any of the creditors may, at its option, resort to
the ordinary courts of justice for them to resolve on the same matters which,
as expressed above, may be subjected to arbitration.Exhibit 4.1

                  acquires Beneficial Ownership of an additional 1% or more of
                  the Voting Stock, unless the acquisition of such additional
                  Voting Stock would not result in such Person becoming an
                  Acquiring Person by reason of subclause (A) or (B) of this

                  outstanding as of such date; provided, further, that any
                  Person described in this clause (iii) shall become an
                  Acquiring Person if (A) such Person, together with all
                  Affiliates and Associates of such Person, after July 19, 2002,
                  acquires Beneficial Ownership of an additional 1% or more of
                  the Voting Stock or (B) such Person, together with all

                  reduces its Beneficial Ownership of the Voting Stock to less

                  Voting Stock, unless in the case of subclause (A) or (B) of
                  this clause (iii) such acquisition of Voting Stock was
                  pursuant to a transaction described in subclauses (ii)(A) or

                  become an Acquiring Person by reason of subclauses (ii)(A) or
                  (ii)(B) above, such Person nonetheless shall become an
                  Acquiring Person in the event such Person (together with all
                  Affiliates and Associates of such Person) thereafter acquires
                  Beneficial Ownership of an additional 1% or more of the Voting
                  Stock, unless the acquisition of such Voting Stock would not
                  result in such person becoming an Acquiring Person by reason
                  of subclause (A) or (B) of clause (ii) above. Notwithstanding
                  the foregoing, if the Board of Directors of the Corporation
                  determines in good faith that a Person who would otherwise be
                  an "Acquiring Person" as defined pursuant to the foregoing
                  provisions of this paragraph (a) has become such
                  inadvertently, and such Person divests as promptly as
                  practicable (as determined in good faith by the Board of
                  Directors of the Corporation) a sufficient number of shares of
                  Voting Stock so that such Person would no longer be an
                  "Acquiring Person" as defined pursuant to the foregoing
                  provisions of this paragraph (a), then such Person shall not
                  be deemed an "Acquiring Person" for any purposes of this
                  Agreement.

                           (aa) "Trading Day" shall have the meaning set forth
                  in Section 11(b) hereof.

                           (bb) "Transfer Tax" shall mean any tax or charge,
                  including any documentary stamp tax, imposed or collected by
                  any governmental or regulatory authority in respect of any
                  transfer of any security, instrument or right, including the
                  Rights, shares of the Common Stock and shares of the Preferred
                  Stock.

                           (cc) "Voting Stock" shall mean (i) the Common Stock
                  of the Corporation and (ii) any other shares of capital stock
                  of the Corporation entitled to vote generally in the election
                  of directors or entitled generally to vote together with the
                  Common Stock in respect of a merger, consolidation, sale of
                  all or substantially all of the Corporation's assets,
                  liquidation, dissolution or winding up. For purposes of this
                  Agreement, a stated percentage of the Voting Stock shall mean
                  a number of shares of the Voting Stock as shall equal in
                  voting power that stated percentage of the total voting power
                  of the then outstanding shares of Voting Stock in the election
                  of a majority of the Board of Directors of the Corporation or
                  in respect of a merger, consolidation, sale of all or
                  substantially all of the Corporation's assets, liquidation,
                  dissolution or winding up.

                  Any determination required to be made by the Board of
                  Directors of the Corporation for purposes of applying the
                  definitions contained in this Section 1 shall be made by a
                  majority of the Board of Directors of the Corporation in its
                  good faith judgment, which determination shall be binding on
                  the Rights Agent and the holders of the Rights.

                  Section 2. Appointment of Rights Agent. The Corporation hereby
appoints the Rights Agent to act as agent for the Corporation and the holders of
the Rights (who, in accordance with Section 3 hereof, shall prior to the
Distribution Date be the holders of Common Stock) in accordance with the terms
and conditions hereof, and the Rights Agent hereby accepts such appointment. The
Corporation may from time to time appoint such Co-Rights Agents as it may deem
necessary or desirable, upon ten (10) days prior written notice to the Rights
Agent. The Rights Agent shall have no duty to supervise, and shall in no event
be liable for, the acts or omissions of any such Co-Rights Agent.

                  Section 3. Issuance of Right Certificates.

                  (a) On the Record Date (or as soon as practicable thereafter),
the Corporation or the Rights Agent shall send a copy of a Summary of Rights, in
substantially the form attached hereto as Exhibit A (the "Summary of Rights"),
by first class mail, postage prepaid, to each record holder of the Common Stock
as of the Record Date, at the address of such holder shown on the records of the
Corporation.

                  (b) Until the Close of Business on the day which is the
earlier of (i) the tenth day after the Stock Acquisition Date or (ii) the tenth
Business Day (or such later date as may be determined by action of the Board of
Directors of the Corporation prior to such time as any Person becomes an
Acquiring Person) after the date of the commencement by any Person (other than
an Exempt Person) of a tender or exchange offer upon the successful consummation
of which such Person, or any Affiliate or Associate of such Person, would be an
Acquiring Person (including any such date which is after the date of this
Agreement and prior to the issuance of the Rights; the earlier of such dates
being herein referred to as the "Distribution Date"), (x) the Rights shall be
evidenced by the certificates for Common Stock (or in the case of uncertificated
shares of Common Stock, by the book-entry account that evidences record
ownership for such shares) registered in the names of the holders of Common
Stock (together with, in the case of certificates for Common Stock outstanding
as of the Record Date, the Summary of Rights) and not by separate Right
certificates and the record holders of such certificates (or such book-entry
accounts) for Common Stock shall be the record holders of the Rights represented
thereby and (y) each Right shall be transferable only simultaneously and
together with the transfer of a share of Common Stock (subject to adjustment as
hereinafter provided). Until the Distribution Date (or, if earlier, the
Expiration Date or Final Expiration Date), the surrender for transfer of any
certificate for Common Stock (or the effectuation of a book-entry transfer of
shares of Common Stock) shall constitute the surrender for transfer of the Right
or Rights associated with the Common Stock evidenced thereby, whether or not
accompanied by a copy of the Summary of Rights.

                  (c) Rights shall be issued in respect of all shares of Common
Stock that become outstanding after the Record Date but prior to the earliest of
the Distribution Date, the Expiration Date or the Final Expiration Date.
Certificates for Common Stock (including, without limitation, certificates
issued upon original issuance, disposition from the Corporation's treasury or
transfer or exchange of Common Stock) after the Record Date but prior to the
earliest of the Distribution Date, the Expiration Date, or the Final Expiration
Date shall have impressed, printed, written or stamped thereon or otherwise
affixed thereto the following legend:

                  This certificate also evidences and entitles the holder hereof
         to the same number of Rights (subject to adjustment) as the number of
         shares of Common Stock represented by this certificate, such Rights
         being on the terms provided under the Rights Agreement by and between
         IMPATH Inc. and American Stock Transfer & Trust Company (the "Rights
         Agent"), dated as of July 19, 2002, as it may be amended from time to
         time (the "Agreement"), the terms of which are incorporated herein by
         reference and a copy of which is on file at the principal executive
         offices of IMPATH Inc. Under certain circumstances, as set forth in the
         Agreement, such Rights shall be evidenced by separate certificates and
         shall no longer be evidenced by this certificate. IMPATH Inc. shall

                                       8
<PAGE>

         mail to the registered holder of this certificate a copy of the
         Agreement without charge within five days after receipt of a written
         request therefor. As provided in Section 7(e) of the Agreement, Rights
         issued to or Beneficially Owned by Acquiring Persons or their
         Affiliates or Associates (as such terms are defined in the Agreement)
         or any subsequent holder of such Rights shall be null and void and may
         not be exercised by or transferred to any Person.

With respect to such certificates containing the foregoing legend, until the
Distribution Date the Rights associated with the Common Stock represented by
such certificates shall be evidenced by such certificates alone, and the
surrender for transfer of any such certificate, except as otherwise provided
herein, shall also constitute the transfer of the Rights associated with the
Common Stock represented thereby. In the event that the Corporation purchases or
otherwise acquires any Common Stock after the Record Date but prior to the
Distribution Date, any Rights associated with such Common Stock shall be deemed
canceled and retired so that the Corporation shall not be entitled to exercise
any Rights associated with the Common Stock which are no longer outstanding.
Notwithstanding this paragraph (c), the omission of a legend shall not affect
the enforceability of any part of this Agreement or the rights of any holder of
the Rights.

                  (d) As soon as practicable after the Distribution Date, the
Corporation will prepare and execute, the Rights Agent will countersign, and the
Corporation will send or cause to be sent (and the Rights Agent will, if
requested, send), by first class mail, postage prepaid, to each record holder of
the Common Stock as of the Close of Business on the Distribution Date, as shown
by the records of the Corporation, at the address of such holder shown on such
records, a certificate in the form provided by Section 4 hereof (a "Right
Certificate"), evidencing one Right (subject to adjustment as provided herein)
for each share of Common Stock so held. As of and after the Distribution Date,
the Rights shall be evidenced solely by Right Certificates and may be
transferred by the transfer of the Right Certificate as permitted hereby,
separately and apart from any transfer of one or more shares of Common Stock.

                  Section 4. Form of Right Certificates. The Right Certificates
(and the forms of election to purchase shares, certificate and assignment to be
printed on the reverse thereof), when, as and if issued, shall be substantially
in the form set forth in Exhibit B hereto and may have such marks of
identification or designation and such legends, summaries or endorsements
printed thereon as may be required to comply with any law or with any rule or
regulation made pursuant thereto or with any rule or regulation of any stock
exchange on which the Common Stock or the Rights may from time to time be listed
or as the Corporation may deem appropriate to conform to usage or otherwise and
as are not inconsistent with the provisions of this Agreement. Subject to the
provisions of Section 22 hereof, Right Certificates evidencing Rights whenever
issued, (i) shall be dated as of the date of issuance of the Rights they
represent and (ii) subject to adjustment from time to time as provided herein,
on their face shall entitle the holders thereof to purchase such number of one
one-thousandths of a share (including fractional shares which are integral

                                       9
<PAGE>

multiples of one-thousandth of a share) of Preferred Stock as shall be set forth
thereon at the price per one one-thousandth of a share of Preferred Stock
payable upon exercise of a Right provided by Section 7(b) hereof, as the same
may from time to time be adjusted as provided herein (the "Exercise Price").

                  Section 5. Countersignature and Registration.

                  (a) Each Right Certificate shall be executed on behalf of the
Corporation by its Chairman of the Board, President or any Vice President,
either manually or by facsimile signature, and have affixed thereto the
Corporation's seal or a facsimile thereof which shall be attested by the
Secretary or an Assistant Secretary of the Corporation, either manually or by
facsimile signature. Each Right Certificate shall be countersigned by the Rights
Agent either manually or by facsimile signature and shall not be valid for any
purpose unless so countersigned. In case any officer of the Corporation who
shall have signed any Right Certificate shall cease to be such officer of the
Corporation before countersignature by the Rights Agent and issuance and
delivery of the certificate by the Corporation, such Right Certificate,
nevertheless, may be countersigned by the Rights Agent and issued and delivered
with the same force and effect as though the person who signed such Right
Certificates had not ceased to be such officer of the Corporation. Any Right
Certificate may be signed on behalf of the Corporation by any person who, on the
date of the execution of such Right Certificate, shall be a proper officer of
the Corporation to sign such Right Certificate, although at the date of the
execution of this Agreement any such person was not such an officer.

                  (b) Following the Distribution Date, the Rights Agent will
keep or cause to be kept, at its principal office or one or more offices
designated as the appropriate place for surrender of Right Certificates upon
exercise or transfer, and in such other locations as may be required by law,
books for registration and transfer of the Right Certificates issued hereunder.
Such books shall show the names and addresses of the respective holders of the
Right Certificates, the number of Rights evidenced on its face by each of the
Right Certificates and the date of each of the Right Certificates.

                  Section 6. Transfer, Split Up, Combination and Exchange of
Right Certificates; Mutilated, Destroyed, Lost or Stolen Right Certificates.

                  (a) Subject to the provisions of Sections 7(e), 7(f) and 14
hereof, at any time after the Close of Business on the Distribution Date, and at
or prior to the Close of Business on the earlier of the Expiration Date or the
Final Expiration Date, any Right Certificate, may be (i) transferred or (ii)
split up, combined or exchanged for one or more other Right Certificates,
entitling the registered holder to purchase a like number of one one-thousandths
of a share of Preferred Stock as the Right Certificate or Rights Certificates
surrendered then entitled such holder to purchase. Any registered holder
desiring to transfer, split up, combine or exchange any Right Certificate shall
surrender the Right Certificate at the office of the Rights Agent designated for
the surrender of Right Certificates with the form of certificate and assignment
on the reverse side thereof duly endorsed (or enclose with such Right
Certificate a written instrument of transfer in form satisfactory to the

                                       10
<PAGE>

Corporation and the Rights Agent), duly executed by the registered holder
thereof or his attorney duly authorized in writing, and with such signature duly
guaranteed. Any registered holder desiring to split up, combine or exchange any
Right Certificate shall make such request in writing delivered to the Rights
Agent, and shall surrender the Right Certificate to be split up, combined or
exchanged at the office of the Rights Agent designated therefor. Thereupon, the
Rights Agent shall countersign and deliver to the person entitled thereto a
Right Certificate or Right Certificates, as the case may be, as so requested.
The Corporation may require payment of a sum sufficient to cover any Transfer
Tax that may be imposed in connection with any transfer, split up, combination
or exchange of any Right Certificates.

                  (b) Subject to the provisions of Sections 7(e), 7(f) and 14
hereof, at any time after the Distribution Date and prior to the Expiration
Date, upon receipt by the Corporation and the Rights Agent of evidence
reasonably satisfactory to them of the loss, theft, destruction or mutilation of
a Right Certificate, and, in case of loss, theft or destruction, of indemnity or
security reasonably satisfactory to them and, if requested by the Corporation,
reimbursement to the Corporation and the Rights Agent of all reasonable expenses
incidental thereto, or upon surrender to the Rights Agent and cancellation of
the Right Certificate if mutilated, the Corporation shall cause a new Right
Certificate of like tenor to be issued and delivered to the registered owner in
lieu of the Right Certificate so lost, stolen, destroyed or mutilated.

                  Section 7. Exercise of Rights; Exercise Price; Expiration Date
of Rights; Invalidation of Certain Rights.

                  (a) The Rights shall not be exercisable until, and shall
become exercisable on, the Distribution Date (unless otherwise provided herein,
including, without limitation, the restrictions on exercisability set forth in
Section 7(e), 23(a) and 27(b) hereof). Except as otherwise provided herein, the
Rights may be exercised, in whole or in part, at any time commencing with the
Distribution Date upon surrender of the Right Certificate, with the form of
election to purchase and certificate on the reverse side thereof duly executed
(with signatures duly guaranteed), to the Rights Agent at the designated office
of the Rights Agent in New York, together with payment of the Exercise Price for
each Right exercised (as the same may have been adjusted as hereinafter
provided), at or prior to the Close of Business on the earlier of (i) July 19,
2012 (the "Final Expiration Date") or (ii) the date on which the Rights are
redeemed as provided in Section 23 hereof or the date on which the Rights are
exchanged as provided in Section 27 hereof (such earlier date being herein
referred to as the "Expiration Date").

                  (b) The Exercise Price shall initially be $140.00 for each one
one-thousandth (1/1,000) of a share of Preferred Stock issued pursuant to the
exercise of a Right. The Exercise Price and the number of one one-thousandths of
a share of Preferred Stock or other securities or property to be acquired upon
exercise of a Right shall be subject to adjustment from time to time as provided
in Sections 11 and 13 hereof. The Exercise Price shall be payable in lawful
money of the United States of America, in accordance with paragraph (c) below.

                                       11
<PAGE>

                  (c) Except as otherwise provided herein, upon receipt of a
Right Certificate representing exercisable Rights with the form of election to
purchase and certificate duly executed, accompanied by payment by certified
check, cashier's check, bank draft or money order payable to the Corporation or
the Rights Agent of the Exercise Price for the shares of Preferred Stock to be
purchased and an amount equal to any applicable Transfer Tax required to be paid
by the holder of the Right Certificate in accordance with Section 9(e) hereof,
the Rights Agent shall thereupon promptly (i) requisition from any transfer
agent of the Preferred Stock of the Corporation one or more certificates
representing the number of shares of Preferred Stock to be so purchased, and the
Corporation hereby authorizes and directs such transfer agent to comply with all
such requests, (ii) as provided in Section 14(b) hereof, at the election of the
Corporation, cause depositary receipts to be issued in lieu of fractional shares
of Preferred Stock, (iii) if the election provided for in the immediately
preceding clause (ii) has not been made, requisition from the Corporation the
amount of cash to be paid in lieu of the issuance of fractional shares (other
than fractions that are integral multiples of one one-thousandth of a share) in
accordance with Section 14(b) hereof, (iv) after receipt of such Preferred Stock
certificates and, if applicable, depositary receipts, cause the same to be
delivered to or upon the order of the registered holder of such Right
Certificate, registered in such name or names as may be designated by such
holder and (v) when appropriate, after receipt, promptly deliver such cash to or
upon the order of the registered holder of such Right Certificate; provided,
however, that in the case of a purchase of securities other than Preferred
Stock, pursuant to Section 13 hereof, the Rights Agent shall promptly take the
appropriate actions corresponding in such case to that referred to in the
foregoing clauses (i) through (v) of this Section 7(c). Notwithstanding the
foregoing provisions of this Section 7(c), the Corporation may suspend the
issuance of shares of Preferred Stock and other securities upon exercise of a
Right for a reasonable period, not in excess of 90 days, during which the
Corporation seeks to register under the Securities Act, and any applicable
securities law of any other jurisdiction, the shares of Preferred Stock or other
securities to be issued pursuant to the Rights; provided, however, that nothing
contained in this Section 7(c) shall relieve the Corporation of its obligations
under Section 9(d) hereof. Upon any such suspension, the Corporation shall issue
a public announcement stating that the exercisability of the Rights has been
temporarily suspended, as well as a public announcement at such time as the
suspension is no longer in effect.

                  (d) In case the registered holder of any Right Certificate
shall exercise less than all the Rights evidenced thereby, a new Right
Certificate evidencing Rights equivalent to the Rights remaining unexercised
shall be issued by the Rights Agent to the registered holder of such Right
Certificate or his assign, subject to the provisions of Section 14(b) hereof.

                  (e) Notwithstanding any provision of this Agreement to the
contrary, from and after the time (the "invalidation time") when any Person
first becomes an Acquiring Person, any Rights that are Beneficially Owned by (x)
such Acquiring Person (or any Associate or Affiliate of such Acquiring Person),
(y) a transferee of such Acquiring Person (or any such Associate or Affiliate)
who becomes a transferee after the invalidation time or (z) a transferee of such

                                       12
<PAGE>

Acquiring Person (or any such Associate or Affiliate) who becomes a transferee
prior to or concurrently with the invalidation time pursuant to either (I) a
transfer from the Acquiring Person (or any such Associate or Affiliate) to
holders of its equity securities or to any Person with whom it has any
continuing agreement, arrangement or understanding regarding the transferred
Rights or (II) a transfer which the Board of Directors of the Corporation has
determined is part of a plan, arrangement or understanding which has the purpose
or effect of avoiding the provisions of this Section 7(e), and subsequent
transferees of such Persons referred to in clause (y) and (z) above, shall be
null and void without any further action and any holder of such Rights shall
thereafter have no rights whatsoever with respect to such Rights under any
provision of this Agreement. No Right Certificate shall be issued pursuant to
Section 3 hereof that represents Rights beneficially owned by an Acquiring
Person or any Affiliate or Associate thereof whose Rights would be null and void
pursuant to the provisions of this Section 7(e); no Right Certificate shall be
issued at any time upon the transfer of any Rights to an Acquiring Person (or an
Affiliate or Associate of such Acquiring Person) whose Rights would be null and
void pursuant to the provisions of this Section 7(e) or any Associate or
Affiliate thereof or to any nominee of such Acquiring Person, Associate or
Affiliate; and any Right Certificate delivered to the Rights Agent for transfer
to an Acquiring Person (or an Associate or Affiliate of such Acquiring Person)
whose Rights would be void pursuant to the provisions of this Section 7(e) shall
be cancelled. The Corporation shall use all reasonable efforts to ensure that
the provisions of this Section 7(e) are complied with, but it shall have no
liability to any holder of Right Certificates or any other Person as a result of
its failure to make any determination with respect to an Acquiring Person or its
Affiliates, Associates or transferees hereunder.

                  (f) Notwithstanding anything in this Agreement to the
contrary, neither the Rights Agent nor the Corporation shall be obligated to
undertake any action with respect to a registered holder upon the occurrence of
any purported exercise as set forth in this Section 7 unless such registered
holder shall have (i) completed and signed the certificate following the form of
election to purchase set forth on the reverse side of the Right Certificate
surrendered for such exercise and (ii) provided such additional evidence of the
identity of the Beneficial Owner (or former Beneficial Owner) or Affiliates or
Associates thereof and such other information as the Corporation or the Rights
Agent shall reasonably request.

                  Section 8. Cancellation and Destruction of Right Certificates.
All Right Certificates surrendered for the purpose of exercise, transfer, split
up, combination or exchange shall, if surrendered to the Corporation or to any
of its agents, be delivered to the Rights Agent for cancellation or in cancelled
form, or, if surrendered to the Rights Agent, shall be cancelled by it, and no
Right Certificates shall be issued in lieu thereof except as expressly permitted
by any of the provisions of this Agreement. The Corporation shall deliver to the
Rights Agent for cancellation and retirement, and the Rights Agent shall cancel
and retire, any Right Certificate purchased or acquired by the Corporation
otherwise than upon the exercise thereof. The Rights Agent shall deliver all
cancelled Right Certificates to the Corporation, or shall, at the written

                                       13
<PAGE>

request of the Corporation, destroy such cancelled Right Certificates, and in
such case shall deliver a certificate of destruction thereof to the Corporation.

                  Section 9. Reservation and Availability of Shares of Preferred
Stock.

                  (a) The Corporation covenants and agrees that it will cause to
be reserved and kept available out of the authorized and unissued shares of
Preferred Stock or out of authorized and issued shares of Preferred Stock held
in its treasury, such number of shares of Preferred Stock as will from time to
time be sufficient to permit the exercise in full of all outstanding Rights.

                  (b) The Corporation shall use its best efforts to cause, from
and after such time as the Rights become exercisable, all shares of Preferred
Stock issued or reserved for issuance in accordance with this Agreement to be
listed, upon official notice of issuance, upon the principal national securities
exchange, if any, upon which the Common Stock is listed or, if the principal
market for the Common Stock is not on any national securities exchange, to be
eligible for quotation in the National Association of Securities Dealers'
Automated Quotation System or any successor thereto or other comparable
quotation system.

                  (c) The Corporation covenants and agrees that it will take all
such action as may be necessary to ensure that all shares of Preferred Stock
delivered upon exercise of Rights shall, at the time of delivery of the
certificates for such shares (subject to payment of the Exercise Price in
respect thereof), be duly and validly authorized and issued and fully paid and
nonassessable shares.

                  (d) The Corporation shall use its best efforts to (i) file, as
soon as practicable following the occurrence of the event described in Section
11(a)(ii), or as soon as is required by law following the Distribution Date, as
the case may be, a registration statement under the Securities Act, with respect
to the shares of Preferred Stock purchasable upon exercise of the Rights on an
appropriate form, (ii) cause such registration statement to become effective as
soon as practicable after such filing, and (iii) cause such registration
statement to remain effective (with a prospectus at all times meeting the
requirements of the Securities Act) until the earlier of (a) the date as of
which the Rights are no longer exercisable for Preferred Stock and (b) the
earlier of the Expiration Date and the Final Expiration Date. The Corporation
may temporarily suspend, for a period of time not to exceed ninety days, the
issuance of shares of Preferred Stock upon exercise of a Right in order to
prepare and file a registration statement under the Securities Act and permit it
to become effective. The Corporation will also take such action as may be
appropriate under, or to ensure compliance with, the securities or "blue sky"
laws of the various states in connection with the exercisability of the Rights.
Notwithstanding any provision of this Agreement to the contrary, the Rights
shall not be exercisable in any jurisdiction unless the requisite qualification
in such jurisdiction shall have been obtained and until a registration statement
under the Securities Act (if required) shall have been declared effective.

                                       14
<PAGE>

                  (e) The Corporation covenants and agrees that it will pay when
due and payable any and all United States federal and state Transfer Taxes which
may be payable in respect of the issuance or delivery of the Right Certificates
or of any shares of Preferred Stock issued or delivered upon the exercise of
Rights. The Corporation shall not, however, be required to pay any Transfer Tax
which may be payable in respect of any transfer or delivery of a Right
Certificate to a Person other than, or the issuance or delivery of certificates
for Preferred Stock upon exercise of Rights in a name other than that of, the
registered holder of the Right Certificate, and the Corporation shall not be
required to issue or deliver a Right Certificate or certificate for Preferred
Stock to a Person other than such registered holder until any such Transfer Tax
shall have been paid (any such Transfer Tax being payable by the holder of such
Right Certificate at the time of surrender) or until it has been established to
the Corporation's satisfaction that no such Transfer Tax is due.

                  (f) The requirements of this Section 9 shall apply to shares
of Common Stock of the Corporation if the Corporation has elected in accordance
with Section 11(a)(iii) hereof to substitute shares of Common Stock for shares
of Preferred Stock that otherwise may be purchased upon the exercise of Rights.

                  Section 10. Preferred Stock Record Date. Each Person in whose
name any certificate for shares of Preferred Stock is issued upon the exercise
of Rights shall for all purposes be deemed to have become the holder of record
of the Preferred Stock represented thereby on, and such certificate shall be
dated as of, the date upon which the Right Certificate evidencing such Rights
was duly surrendered and payment of the Exercise Price (and any applicable
Transfer Taxes) was made; provided, however, that, if the date of such surrender
and payment is a date upon which the Preferred Stock transfer books of the
Corporation are closed, such Person shall be deemed to have become the record
holder of such shares on, and such certificate shall be dated as of, the next
succeeding Business Day on which the Preferred Stock transfer books of the
Corporation are open.

                  Section 11. Adjustment of Exercise Price or Number of Shares.
The Exercise Price and the number of shares of Preferred Stock which may be
purchased upon exercise of a Right are subject to adjustment from time to time
as provided in this Section 11.

                  (a) (i) In the event the Corporation shall at any time after
                  the date of this Agreement (A) declare or pay any dividend on
                  Common Stock payable in shares of Common Stock, (B) subdivide
                  or split the outstanding shares of Common Stock into a greater
                  number of shares or (C) combine or consolidate the outstanding
                  shares of Common Stock into a smaller number of shares or
                  effect a reverse split of the outstanding shares of Common
                  Stock, then and in each such event the number of one
                  one-thousandths of a share of Preferred Stock issuable upon
                  the exercise of a Right after the record date for such event
                  (if one shall have been established or, if not, after the date
                  of such event) shall be the number of one one-thousandths of a

                                       15
<PAGE>

                  share of Preferred Stock issuable immediately prior to such
                  event multiplied by a fraction, the numerator of which is the
                  number of shares of Common Stock outstanding immediately prior
                  to such event and the denominator of which is the number of
                  shares of Common Stock outstanding immediately after such
                  event, and the Exercise Price to be in effect after the record
                  date for such event (if one shall have been established or, if
                  not, after the date of such event) shall be determined by
                  multiplying the Exercise Price in effect immediately prior to
                  such event by such fraction. If an event occurs which would
                  require an adjustment under both this Section 11(a)(i) and
                  Section 11(a)(ii) hereof, the adjustment provided for in this
                  Section 11(a)(i) shall be in addition to, and shall be made
                  prior to, any adjustment required pursuant to Section
                  11(a)(ii).

                  (ii) Subject to Section 27 hereof, in the event that any
                  Person shall become an Acquiring Person, then, subject to the
                  last sentence of Section 23(a) hereof and except as otherwise
                  provided in this Section 11, each holder of a Right, except as
                  provided in Section 7(e) hereof, shall thereafter have the
                  right to receive upon exercise of such Right in accordance
                  with the terms of this Agreement and payment of the Exercise
                  Price, such number of one one-thousandths of a share of
                  Preferred Stock as shall equal the result obtained by (1)
                  multiplying the then current Exercise Price by the number of
                  one one-thousandths of a share of Preferred Stock for which a
                  Right would, absent adjustment pursuant to this Section
                  11(a)(ii), be then exercisable and dividing the product by (2)
                  50% of the proportionate Fair Market Value of one
                  one-thousandth of a share of the Preferred Stock (determined
                  pursuant to Section 11(b) hereof) on the Stock Acquisition
                  Date in respect of such event; provided, however, if the
                  transaction that would otherwise give rise to the foregoing
                  adjustment is also subject to the provisions of Section 13
                  hereof, then only the provisions of Section 13 hereof shall
                  apply and no adjustment shall be made pursuant to this Section
                  11(a)(ii).

                  (iii) In the event that the Corporation does not have
                  available sufficient authorized but unissued Preferred Stock
                  to permit the exercise in full of the Rights in accordance
                  with the foregoing subparagraph (ii), the Corporation shall
                  take all such action as may be necessary to authorize and
                  reserve for issuance such number of additional shares of
                  Preferred Stock as may from time to time be required to be
                  issued upon the exercise in full of all Rights from time to
                  time outstanding and, if necessary, shall use its best efforts
                  to obtain stockholder approval thereof. In lieu of issuing
                  shares of Preferred Stock in accordance with the foregoing
                  subparagraph (ii), the Corporation may, if the Board of
                  Directors of the Corporation determines that such action is
                  necessary or appropriate, elect to issue or pay, upon the
                  exercise of the Rights, cash, property, shares of Preferred
                  Stock or Common Stock, or any combination thereof, having an
                  aggregate Fair Market Value equal to the Fair Market Value of

                                       16
<PAGE>

                  the shares of Preferred Stock which otherwise would have been
                  issuable pursuant to Section 11(a)(ii) hereof as of the date
                  the Board of Directors of the Corporation makes such election
                  (which Fair Market Value shall be determined as provided by
                  Section 11(b) hereof). Subject to Section 23 hereof, any such
                  election by the Board of Directors of the Corporation must be
                  made and publicly announced within thirty (30) days after the
                  date on which the event described in Section 11(a)(ii) occurs
                  and shall be applicable with respect to all Rights exercised
                  after such public announcement. Notice of such election shall
                  promptly be given to the Rights Agent.

                  (b) For the purpose of this Agreement, the "Fair Market Value"
of any share of Preferred Stock, Common Stock or any other stock or any Right or
other security or any other property on any date shall be determined as provided
in this Section 11(b). In the case of a publicly traded (as such term is
hereinafter defined) stock or other security, the Fair Market Value thereof on
any date shall be deemed to be the average of the daily closing prices per share
of such stock or per unit of such other security for the 30 consecutive Trading
Days (as such term is hereinafter defined) immediately prior to but not
including such date; provided, however, that in the event that the Fair Market
Value of any share of Common Stock is to be determined as of a date that is
within 30 Trading Days after (i) the ex-dividend date for a dividend or
distribution on the Common Stock payable in shares of Common Stock or securities
convertible into shares of Common Stock or (ii) the effective date of any
subdivision, split, combination, consolidation, reverse stock split or
reclassification of the Common Stock, then, and in each such case, the Fair
Market Value shall be appropriately adjusted by the Board of Directors of the
Corporation to take into account such dividend, distribution, subdivision,
split, combination, consolidation, reverse stock split or reclassification. The
closing price for any day shall be the last sale price, regular way, or, in case
no such sale takes place on such day, the average of the closing bid and asked
prices, regular way (in either case, as reported in the applicable transaction
reporting system with respect to securities listed or admitted to trading on the
Nasdaq National Market), or, if the securities are not listed or admitted to
trading on the Nasdaq National Market, as reported in the applicable transaction
reporting system with respect to securities listed on the principal national
securities exchange or Nasdaq market (which, if approved by the Board of
Directors of the Corporation, may be a securities exchange of a country other
than the United States of America) on which such security is listed or admitted
to trading; or, if not listed or admitted to trading on any such national
securities exchange or Nasdaq market, the last quoted price (or, if not so
quoted, the average of the high bid and low asked prices) in the
over-the-counter market, as reported by the National Association of Securities
Dealers, Inc. Automated Quotation System ("NASDAQ") or such other quotation
reporting system then in use in the United States of America; or, if no bids for
such security are so quoted, the average of the closing bid and asked prices as
furnished by a professional market maker making a market in such security
selected by the Board of Directors of the Corporation. The term "Trading Day"
shall mean a day on which the principal national securities exchange or Nasdaq

                                       17
<PAGE>

market on which such security is listed or admitted to trading is open for the
transaction of business or, if such security is not listed or admitted to
trading on any national securities exchange or Nasdaq market, a Business Day.
For purposes of this Section 11(b), a stock or other security shall be
considered "publicly traded" only (i) if registered under Section 12 of the
Exchange Act or exempt from such registration pursuant to Section 12(g)(2)(B),
(C) or (G) of the Exchange Act or (ii) if traded on a national securities
exchange of a country other than the United States of America approved by the
Board of Directors of the Corporation or (iii) if, in the judgment of the Board
of Directors of the Corporation, there is sufficient active trading in such
stock or other security that reported trading transactions therein fairly
reflect the fair market value thereof. If a security is not publicly traded,
"Fair Market Value" shall mean the fair value per share of stock or per other
unit of such other security, as determined by an independent investment banking
firm experienced in the valuation of securities selected in good faith by the
Board of Directors of the Corporation, or, if no such investment banking firm
is, in the good faith judgment of the Board of Directors of the Corporation,
available to make such determination, as determined in good faith by the Board
of Directors of the Corporation; provided, however, that for purposes of making
the adjustment provided for by Section 11(a)(ii) hereof, the Fair Market Value
of a share of Preferred Stock, unless the Preferred Stock shall at the time be
publicly traded (in which case its Fair Market Value shall be determined
pursuant to the foregoing provisions of this Section 11(b)), shall be 100% of
the product of the Fair Market Value of a share of Common Stock multiplied by
the higher of the then Dividend Multiple or Vote Multiple applicable to the
Preferred Stock (as defined in the certificate of designations of the
Corporation relating to the Preferred Stock); provided, however, that the Board
of Directors of the Corporation may, by resolution, determine that the Fair
Market Value of a share of Preferred Stock shall be more than such amount but
not more than 110% of the product of the then Fair Market Value of a share of
Common Stock multiplied by the higher of the then Dividend Multiple or Vote
Multiple applicable to the Preferred Stock. In the case of property other than
securities, the "Fair Market Value" thereof shall be determined in good faith by
the Board of Directors of the Corporation based upon such appraisals or
valuation reports of such independent experts as the Board of Directors of the
Corporation shall in good faith determine to be appropriate in accordance with
good business practices and fair to the interests of the holders of Rights. Any
determination made by the Board of Directors of the Corporation as provided for
by this Section 11(b) shall be described in a statement filed by the Corporation
with the Rights Agent, shall be effective thereupon and only thereupon and shall
be binding upon the Rights Agent and, as provided by Section 34 hereof, all
holders of Rights.

                  (c) In case the Corporation shall fix a record date for the
issuance of rights, options or warrants to all holders of Common Stock entitling
them (for a period expiring within 45 calendar days after such record date) to
subscribe for or purchase Common Stock or securities convertible into Common
Stock at a price per share (or having a conversion price per share, if a
security convertible into Common Stock) less than the then current per share
Fair Market Value of the Common Stock on such record date, the Exercise Price to
be in effect after such record date shall be determined by multiplying the

                                       18
<PAGE>

Exercise Price in effect immediately prior to such record date by a fraction,
the numerator of which shall be the number of shares of Common Stock outstanding
on such record date plus the number of shares of Common Stock which the
aggregate offering price of the total number of shares of Common Stock so to be
offered (and/or the aggregate initial conversion price of the convertible
securities so to be offered) would purchase at such current Fair Market Value
and the denominator of which shall be the number of shares of Common Stock
outstanding on such record date plus the number of additional shares of Common
Stock to be offered for subscription or purchase (or into which the convertible
securities so to be offered are initially convertible). In case such
subscription price may be paid in a consideration part or all of which shall be
in a form other than cash, the value of such consideration shall be as
determined in good faith by the Board of Directors of the Corporation, whose
determination shall be described in a statement filed with the Rights Agent.
Shares of Common Stock owned by or held for the account of the Corporation shall
not be deemed outstanding for the purpose of any such computation. Such
adjustment shall be made successively whenever such a record date is fixed and
in the event that such rights, options or warrants are not so issued, the
Exercise Price shall be adjusted to be the Exercise Price which would then be in
effect if such record date had not been fixed.

                  (d) In case the Corporation shall fix a record date for the
making of a distribution to all holders of the Common Stock (including any such
distribution made in connection with a consolidation or merger in which the
Corporation is the continuing or surviving corporation) of evidences of
indebtedness of the Corporation or any of its Subsidiaries, cash (other than a
regular quarterly cash dividend not in excess of 150% of the previous regular
quarterly cash dividend), other assets (other than a dividend payable in shares
of Common Stock) or options, rights or warrants to subscribe for shares of the
Corporation or any Subsidiary (excluding those referred to in Section 11(c)
hereof), the Exercise Price to be in effect after such record date shall be
determined by multiplying the Exercise Price in effect immediately prior to such
record date by a fraction, the numerator of which shall be the Fair Market Value
of the shares of Common Stock on such record date, less the fair market value
(as determined in good faith by the Board of Directors of the Corporation, whose
determination shall be described in a statement filed with the Rights Agent) of
the portion of the assets or evidences of indebtedness or options, rights or
warrants so to be distributed in respect of one share of Common Stock, and the
denominator of which shall be such current Fair Market Value of the shares of
Common Stock. Such adjustment shall be made successively whenever such a record
date is fixed, and, in the event that such distribution is not so made
notwithstanding the setting of a record date therefor, the Exercise Price shall
again be adjusted to be the Exercise Price which would then be in effect if such
record date had not been fixed.

                  (e) Unless the Corporation shall have exercised its election
as provided in Section 11(f), upon each adjustment of the Exercise Price as a
result of the calculations made in Section 11(c) or (d), each Right outstanding
immediately prior to the making of such adjustment shall thereafter evidence the
right to purchase, at the adjusted Exercise Price, that number of one
one-thousandths of a share of Preferred Stock obtained by (i) multiplying (x)

                                       19
<PAGE>

the number of one one-thousandths of a share of Preferred Stock that could be
purchased upon exercise of a Right immediately prior to the adjustment pursuant
to this Section 11(e) by (y) the Exercise Price in effect immediately prior to
such adjustment of the Exercise Price and (ii) dividing the product so obtained
by the Exercise Price in effect immediately after such adjustment of the
Exercise Price.

                  (f) The Corporation may elect, on or after the date of any
adjustment of the Exercise Price pursuant to Section 11(c) or 11(d), to adjust
the number of Rights in substitution for any adjustment pursuant to Section
11(e) in the number of one one-thousandths of a share of Preferred Stock
purchasable upon the exercise of a Right. Each of the Rights outstanding after
such adjustment of the number of Rights shall be exercisable for the number of
one one-thousandths of a share of Preferred Stock for which a Right was
exercisable immediately prior to such adjustment. Each Right held of record
prior to such adjustment of the number of Rights shall become that number of
Rights obtained by dividing the Exercise Price in effect immediately prior to
adjustment of the Exercise Price by the Exercise Price in effect immediately
after adjustment of the Exercise Price. The Corporation shall make a public
announcement of its election to adjust the number of Rights, indicating the
record date for the adjustment, and, if known at the time, the amount of the
adjustment to be made. This record date may be the date on which the Exercise
Price is adjusted or any day thereafter, but, if the Right Certificates have
been issued, shall be at least 10 days later than the date of the public
announcement. If the Right Certificates have been issued, upon each adjustment
of the number of Rights pursuant to this Section 11(f), the Corporation shall,
as promptly as practicable, cause to be distributed to holders of record of
Right Certificates on such record date Right Certificates evidencing, subject to
Section 14 hereof, the additional Rights, if any, to which such holders shall be
entitled as a result of such adjustment, or, at the option of the Corporation,
shall cause to be distributed to such holders of record in substitution and
replacement for the Right Certificates held by such holders prior to the date of
adjustment, and upon surrender thereof, if required by the Corporation, new
Right Certificates evidencing all the Rights to which such holders shall be
entitled after such adjustment. Right Certificates so to be distributed shall be
issued, executed and countersigned in the manner provided for herein and shall
be registered in the names of the holders of record of Right Certificates on the
record date specified in the public announcement.

                  (g) All calculations under this Section 11 shall be made to
the nearest cent or to the nearest one one-thousandth of a share, as the case
may be.

                  (h) Irrespective of any adjustment or change in the Exercise
Price or the number of shares of Preferred Stock issuable upon the exercise of
the Rights, the Right Certificates theretofore and thereafter issued may
continue to express the Exercise Price and the number of shares to be issued
upon exercise of the Rights as in the initial Right Certificates issued
hereunder but, nevertheless, shall represent the Rights as so adjusted.

                  (i) Before taking any action that would cause an adjustment
reducing the purchase price per whole share of Preferred Stock upon exercise of
the Rights below the then par value, if any, of the shares of Preferred Stock,

                                       20
<PAGE>

the Corporation shall use its best efforts to take any corporate action which
may, in the opinion of its counsel, be necessary in order that the Corporation
may validly and legally issue fully paid and non-assessable shares of such
Preferred Stock at such adjusted purchase price per share.

                  (j) Anything in this Section 11 to the contrary
notwithstanding, in the event of any reclassification of stock of the
Corporation or any recapitalization, reorganization or partial liquidation of
the Corporation or similar transaction, the Corporation shall be entitled to
make such further adjustments in the number of shares of Preferred Stock which
may be acquired upon exercise of the Rights, and such adjustments in the
Exercise Price therefor, in addition to those adjustments expressly required by
the other paragraphs of this Section 11, as the Board of Directors of the
Corporation shall determine to be necessary or appropriate in order for the
holders of the Rights in such event to be treated equitably and in accordance
with the purpose and intent of this Agreement or in order that any such event
shall not, but for such adjustment, in the opinion of counsel to the
Corporation, result in the stockholders of the Corporation being subject to any
United States federal income tax liability by reason thereof.

                  (k) If as a result of an adjustment made pursuant to Section
11(a) hereof, the holder of any Right thereafter exercised shall become entitled
to receive any shares of capital stock of the Corporation other than the
Preferred Stock, thereafter the Exercise Price and the number of such other
shares so receivable upon exercise of a Right shall be subject to adjustment
from time to time in a manner and on terms as nearly equivalent as practicable
to the provisions with respect to the Preferred Stock contained in Sections
11(a), 11(c), 11(d), 11(e), 11(f) and 11(j) hereof, as applicable, and the
provisions of Sections 7, 9, 10, 13 and 14 hereof with respect to the Preferred
Stock shall apply on like terms to any such other shares.

                  Section 12. Certification of Adjusted Exercise Price or Number
of Shares. Whenever an adjustment is made as provided in Section 11, 13, 23(c)
or 27 hereof, the Corporation shall (a) promptly prepare a certificate setting
forth such adjustment, and a brief statement of the facts giving rise to such
adjustment, (b) promptly file with the Rights Agent and with each transfer agent
for the Preferred Stock a copy of such certificate and (c) mail a brief summary
thereof to each holder of a Right Certificate in accordance with Section 25.
Notwithstanding the foregoing sentence, the failure of the Corporation to make
such certification or give such notice shall not affect the validity of or the
force or effect of the requirement for such adjustment. Any adjustment to be
made pursuant to Section 11, 13, 23(c) or 27 hereof shall be effective as of the
date of the event giving rise to such adjustment. The Rights Agent shall be
fully protected in relying on any such certificate and on any adjustment therein
contained and shall not be deemed to have knowledge of any adjustment unless and
until it shall have received such certificate.

                                       21

                  Section 13. Consolidation, Merger or Sale or Transfer of
Assets or Earning Power.

                  (a) In the event that, at any time after the time that any
Person becomes an Acquiring Person, (x) the Corporation shall, directly or
indirectly, consolidate with, or merge with and into, any other Person or
Persons (other than an Exempt Person) and the Corporation shall not be the
surviving or continuing corporation of such consolidation or merger, or (y) any
Person or Persons (other than an Exempt Person) shall, directly or indirectly,
consolidate with, or merge with and into, the Corporation, and the Corporation
shall be the continuing or surviving corporation of such consolidation or merger
and, in connection with such consolidation or merger, all or part of the
outstanding shares of Common Stock shall be changed or converted into or
exchanged for stock or other securities of any other Person (other than an
Exempt Person) or of the Corporation or cash or any other property, or (z) the
Corporation or one or more of its Subsidiaries shall, directly or indirectly,
sell or otherwise transfer to any other Person (other than an Exempt Person) in
one or more transactions, assets or earning power aggregating more than 50% of
the assets or earning power of the Corporation and its Subsidiaries (taken as a
whole), then, on the first occurrence of any such event, proper provision shall
be made so that: (i) each holder of record of a Right, except as provided in
Section 7(e) hereof, shall thereafter have the right to receive, upon the
exercise thereof at a price equal to the then current Exercise Price multiplied
by the number of one one-thousandths of a share of Preferred Stock for which a
Right is then exercisable, in accordance with the terms of this Agreement and in
lieu of shares of Preferred Stock, such number of shares of validly issued,
fully paid, non-assessable and freely tradeable Common Stock of the Principal
Party (as defined in Section 13(b) hereof), not subject to any liens,
encumbrances, rights of first refusal or other adverse claims, as shall equal
the result obtained by (1) multiplying the then current Exercise Price by the
number of one one-thousandths of a share of Preferred Stock for which a Right is
then exercisable and dividing that product by (2) 50% of the then per share Fair
Market Value of the Common Stock of the Principal Party on the date of the
consummation of such consolidation, merger, sale or transfer; provided, however,
that the Exercise Price (as adjusted) and the number of shares of Common Stock
of such Principal Party so receivable upon exercise of a Right shall be subject
to further adjustment as appropriate in accordance with Section 11 hereof to
reflect any events occurring in respect of the Common Stock of such Principal
Party after the occurrence of such consolidation, merger, sale or transfer; (ii)
such Principal Party shall thereafter be liable for, and shall assume, by virtue
of such consolidation, merger, sale or transfer, all the obligations and duties
of the Corporation pursuant to this Agreement; (iii) the term "Corporation" for
all purposes of this Agreement shall thereafter be deemed to refer to such
Principal Party; (iv) such Principal Party shall take such steps (including, but
not limited to, the reservation of a sufficient number of shares of its Common
Stock in accordance with the provisions of Section 9 hereof applicable to the
reservation of Preferred Stock) in connection with such consummation as may be
necessary to assure that the provisions hereof shall thereafter be applicable,
as nearly as reasonably may be, in relation to its shares of Common Stock
thereafter deliverable upon the exercise of the Rights; provided, however, that,
upon the subsequent occurrence of any merger, consolidation, sale of all or

                                       22
<PAGE>

substantially all of the assets, recapitalization, reclassification of shares,
reorganization or other extraordinary transaction in respect of such Principal
Party, each holder of a Right shall thereupon be entitled to receive, upon
exercise of a Right and payment of the Exercise Price, such cash, shares,
rights, warrants and other property which such holder would have been entitled
to receive had it, at the time of such transaction, owned the shares of Common
Stock of the Principal Party purchasable upon the exercise of a Right, and such
Principal Party shall take such steps (including, but not limited to,
reservation of shares of stock) as may be necessary to permit the subsequent
exercise of the Rights in accordance with the terms hereof for such cash,
shares, rights, warrants and other property; and (v) the provisions of Section
11(a)(ii) hereof shall be of no effect following the occurrence of any event
described in clause (x), (y) or (z) above of this Section 13(a).

                  (b) "Principal Party" shall mean

                           (i) in the case of any transaction described in
                  clause (x) or (y) of the first sentence of Section 13(a)
                  hereof: (A) the Person that is the issuer of the securities
                  into which shares of Common Stock of the Corporation are
                  changed or otherwise exchanged or converted in such merger or
                  consolidation, or, if there is more than one such issuer, the
                  issuer of the Common Stock of which has the greatest market
                  value or (B) if no securities are so issued, (I) the Person
                  that is the other party to the merger or consolidation and
                  that survives such merger or consolidation, or, if there is
                  more than one such Person, the Person the Common Stock of
                  which has the greatest market value or (II) if the Person that
                  is the other party to the merger or consolidation does not
                  survive the merger or consolidation, the Person that does
                  survive the merger or consolidation (including the Corporation
                  if it survives); and

                           (ii) in the case of any transaction described in
                  clause (z) of the first sentence in Section 13(a), the Person
                  that is the party receiving the greatest portion of the assets
                  or earning power transferred pursuant to such transaction or
                  transactions, or, if each Person that is a party to such
                  transaction or transactions receives the same portion of the
                  assets or earning power so transferred or if the Person
                  receiving the greatest portion of the assets or earning power
                  cannot be determined, whichever of such Persons as is the
                  issuer of Common Stock having the greatest market value of
                  shares outstanding;

provided, however, that in any such case, if the Common Stock of such Person is
not at such time and has not been continuously over the preceding 12-month
period registered under Section 12 of the Exchange Act, then (1) if such Person
is a direct or indirect Subsidiary of another Person the Common Stock of which
is and has been so registered, the term "Principal Party" shall refer to such
other Person, or (2) if such Person is a Subsidiary, directly or indirectly, of
more than one Person, the Common Stocks of all of which are and have been so
registered, the term "Principal Party" shall refer to whichever of such Persons

                                       23
<PAGE>

is the issuer of the Common Stock having the greatest market value of shares
outstanding, or (3) if such Person is owned, directly or indirectly, by a joint
venture formed by two or more Persons that are not owned, directly or
indirectly, by the same Person, the rules set forth in clauses (1) and (2) above
shall apply to each of the owners having an interest in the venture as if the
Person owned by the joint venture was a Subsidiary of both or all of such joint
venturers, and the Principal Party in each such case shall bear the obligations
set forth in this Section 13 in the same ratio as its interest in such Person
bears to the total of such interests.

                  (c) The Corporation shall not consummate any consolidation,
merger or sale or transfer of assets or earning power referred to in Section
13(a) unless the Principal Party shall have a sufficient number of authorized
shares of its Common Stock that have not been issued or reserved for issuance to
permit exercise in full of all Rights in accordance with this Section 13 and
unless prior thereto the Corporation and the Principal Party involved therein
shall have executed and delivered to the Rights Agent an agreement confirming
that the Principal Party shall, upon consummation of such consolidation, merger
or sale or transfer of assets or earning power, assume this Agreement in
accordance with Section 13(a) hereof and that all rights of first refusal or
preemptive rights in respect of the issuance of shares of Common Stock of the
Principal Party upon exercise of outstanding Rights have been waived and that
such transaction shall not result in a default by the Principal Party under this
Agreement, and further providing that, as soon as practicable after the date of
any consolidation, merger or sale or transfer of assets or earning power
referred to in Section 13(a) hereof, the Principal Party will:

                           (i) prepare and file a registration statement under
                  the Securities Act with respect to the Rights and the
                  securities purchasable upon exercise of the Rights on an
                  appropriate form, use its best efforts to cause such
                  registration statement to become effective as soon as
                  practicable after such filing and use its best efforts to
                  cause such registration statement to remain effective (with a
                  prospectus at all times meeting the requirements of the
                  Securities Act) until the date of expiration of the Rights,
                  and similarly comply with applicable state securities laws;

                           (ii) use its best efforts to list (or continue the
                  listing of) the Rights and the securities purchasable upon
                  exercise of the Rights on a national securities exchange or to
                  meet the eligibility requirements for quotation on NASDAQ;

                           (iii) deliver to holders of the Rights historical
                  financial statements for the Principal Party which comply in
                  all respects with the requirements for registration on Form 10
                  (or any successor form) under the Exchange Act. In the event
                  that any of the transactions described in Section 13(a) hereof
                  shall occur at any time after the occurrence of a transaction
                  described in Section 11(a)(ii) hereof, the Rights which have
                  not theretofore been exercised shall, subject to the

                                       24
<PAGE>

                  provisions of Section 7(e) hereof, thereafter be exercisable
                  in the manner described in Section 13(a); and

                           (iv) obtain waivers of any rights of first refusal or
                  preemptive rights in respect of the Common Stock of the
                  Principal Party subject to purchase upon exercise of
                  outstanding Rights.

                  (d) In case the Principal Party which is to be a party to a
transaction referred to in this Section 13 has a provision in any of its
authorized securities or in its Restated Certificate of Incorporation or By-laws
or other instrument governing its affairs, which provision would have the effect
of (i) causing such Principal Party to issue, in connection with, or as a
consequence of, the consummation of a transaction referred to in this Section
13, shares of Common Stock of such Principal Party at less than the then Fair
Market Value per share (determined pursuant to Section 11(b) hereof) or
securities exercisable for, or convertible into, Common Stock of such Principal
Party at less than such then Fair Market Value (other than to holders of Rights
pursuant to this Section 13) or (ii) providing for any special tax or similar
payment in connection with the issuance to any holder of a Right of Common Stock
of such Principal Party pursuant to the provisions of this Section 13, then, in
such event, the Corporation shall not consummate any such transaction unless
prior thereto the Corporation and such Principal Party shall have executed and
delivered to the Rights Agent a supplemental agreement providing that the
provision in question of such Principal Party shall have been canceled, waived
or amended, or that the authorized securities shall be redeemed, so that the
applicable provision will have no effect in connection with, or as a consequence
of, the consummation of the proposed transaction.

                  (e) The Corporation covenants and agrees that it shall not, at
any time after any Person becomes an Acquiring Person, enter into any
transaction of the type described in clauses (x) through (z) of the first
sentence of Section 13(a) hereof if (i) at the time of or immediately after such
consolidation, merger, sale, transfer or other transaction there are any rights,
warrants or other instruments or securities outstanding or agreements in effect
which would substantially diminish or otherwise eliminate the benefits intended
to be afforded by the Rights, (ii) prior to, simultaneously with or immediately
after such consolidation, merger, sale, transfer or other transaction, the
stockholders of the Person who constitutes, or would constitute, the Principal
Party for purposes of Section 13(a) hereof shall have received a distribution of
Rights previously owned by such Person or any of its Affiliates or Associates or
(iii) the form or nature of organization of the Principal Party would preclude
or limit the exercisability of the Rights.

                  Section 14. Fractional Rights and Fractional Shares.

                  (a) The Corporation shall not be required to issue fractions
of Rights or to distribute Right Certificates which evidence fractional Rights
(i.e., Rights to acquire less than one one-thousandth of a share of Preferred
Stock), unless such fractional Rights result from a transaction referred to in
Section 11(a)(i) or 11(f) hereof. If the Corporation shall determine not to

                                       25
<PAGE>

issue such fractional Rights, then, in lieu of such fractional Rights, there
shall be paid to the holders of record of the Right Certificates with regard to
which such fractional Rights would otherwise be issuable, an amount in cash
equal to the same fraction of the Fair Market Value of a whole Right.

                  (b) The Corporation shall not be required to issue fractions
of shares of Preferred Stock (other than fractions that are integral multiples
of one one-thousandth of a share) upon exercise of the Rights or to distribute
certificates which evidence fractional shares (other than fractions that are
integral multiples of one one-thousandth of a share). In lieu of issuing
fractions of shares of Preferred Stock, the Corporation may, at its election,
issue depositary receipts evidencing fractions of shares pursuant to an
appropriate agreement between the Corporation and a depositary selected by it,
provided that such agreement shall provide that the holders of such depositary
receipts shall have all of the rights, privileges and preferences to which they
would be entitled as owners of the Preferred Stock. With respect to fractional
shares that are not integral multiples of one one-thousandth of a share, if the
Corporation does not issue such fractional shares or depositary receipts in lieu
thereof, there shall be paid to the holders of record of Right Certificates at
the time such Right Certificates are exercised as herein provided an amount in
cash equal to the same fraction of the Fair Market Value of a share of Preferred
Stock.

                  (c) The holder of a Right by the acceptance of a Right
expressly waives his right to receive any fractional Right or any fractional
shares of Preferred Stock (other than fractions which are integral multiples of
one one-thousandth of a share) upon exercise of a Right.

                  Section 15. Rights of Action. All rights of action in respect
of this Agreement, except the rights of action given to the Rights Agent in
Section 18 hereof, are vested in the respective registered holders of the Right
Certificates (and, prior to the Distribution Date, the holders of record of the
Common Stock), and any holder of record of any Right Certificate (or, prior to
the Distribution Date, of the Common Stock), without the consent of the Rights
Agent or of the holder of any other Right Certificate (or, prior to the
Distribution Date, of the Common Stock), may, in his own behalf and for his own
benefit, enforce, and may institute and maintain any suit, action or proceeding
against the Corporation to enforce, or otherwise act in respect of, his right to
exercise the Rights evidenced by such Right Certificate in the manner provided
in such Right Certificate and in this Agreement. Without limiting the foregoing
or any remedies available to the holders of Rights, it is specifically
acknowledged that the holders of Rights would not have an adequate remedy at law
for any breach of this Agreement and will be entitled to specific performance of
the obligations under, and injunctive relief against actual or threatened
violations of, the obligations of any Person subject to this Agreement.

                  Section 16. Agreement of Right Holders. Each holder of a
Right, by accepting the same, consents and agrees with the Corporation and the
Rights Agent and with every other holder of a Right that:

                                       26
<PAGE>

                           (a) prior to the Distribution Date, the Rights shall
                  be evidenced by the certificates for Common Stock (or in the
                  case of uncertificated shares of Common Stock, by the
                  book-entry account that evidences record ownership of such
                  shares) registered in the name of the holders of Common Stock
                  (together, as applicable, with the Summary of Rights), which
                  certificates for Common Stock (or book-entry account) shall
                  also constitute certificates for Rights, and not by separate
                  Right Certificates, and each Right shall be transferable only
                  simultaneously and together with the transfer of shares of
                  Common Stock;

                           (b) after the Distribution Date, the Right
                  Certificates are transferable only on the registry books of
                  the Rights Agent if surrendered at the office of the Rights
                  Agent designated for such purpose, duly endorsed or
                  accompanied by a proper instrument of transfer; and

                           (c) the Corporation and the Rights Agent may deem and
                  treat the Person in whose name the Right Certificate (or,
                  prior to the Distribution Date, the associated Common Stock
                  certificate or, in the case of uncertificated shares of Common
                  Stock, the book-entry account evidencing record ownership of
                  such shares) is registered as the absolute owner thereof and
                  of the Rights evidenced thereby (notwithstanding any notations
                  of ownership or writing on the Right Certificates or the
                  associated Common Stock certificate made by anyone other than
                  the Corporation or the Rights Agent) for all purposes
                  whatsoever, and neither the Corporation nor the Rights Agent
                  shall be affected by any notice to the contrary.

                  Section 17. Right Certificate Holder Not Deemed a Stockholder.
No holder, as such, of any Right Certificate shall be entitled to vote, receive
dividends or be deemed for any purpose the holder of Preferred Stock or any
other securities which may at any time be issuable on the exercise of the Rights
represented thereby, nor shall anything contained herein or in any Right
Certificate be construed to confer upon the holder of any Right Certificate, as
such, any of the rights of a stockholder or other securityholder of the
Corporation or of a securityholder of any other Person or any right to vote for
the election of directors or upon any matter submitted to stockholders at any
meeting thereof, or to give or withhold consent to any corporate action or
securityholder action, or to receive notice of meetings or other actions
affecting stockholders or securityholders (except as provided in Section 24
hereof), or to receive dividends or subscription rights, or otherwise, except in
any such case the rights, if any, in respect thereof provided by this Agreement,
until the Right or Rights evidenced by such Right Certificate shall have been
exercised in accordance with the provisions hereof for such stock or other
security.

                  Section 18. Concerning the Rights Agent.

                  (a) The Corporation agrees to pay to the Rights Agent
reasonable compensation for all services rendered by it hereunder and, from time
to time, on demand of the Rights Agent, its reasonable expenses and counsel fees
and other disbursements incurred in the administration and execution of this
Agreement and the exercise and performance of its duties hereunder. The
Corporation also agrees to indemnify the Rights Agent for, and to hold it
harmless against, any loss, liability, or expense, incurred without negligence,
bad faith or willful misconduct on the part of the Rights Agent, for anything
done or omitted to be done by the Rights Agent in connection with the acceptance
and administration of this Agreement, including the cost and expenses of
defending against any claim of liability relating to the Rights or this
Agreement.

                  (b) The Rights Agent shall be protected against, and shall
incur no liability for or in respect of, any action taken, suffered or omitted
by it in connection with its administration of this Agreement in reliance upon
any Right Certificate or certificate for Preferred Stock or for other securities
of the Corporation, instrument of assignment or transfer, power of attorney,
endorsement, affidavit, letter, notice, direction, consent, certificate,
statement or other paper or document believed by it to be genuine and to be
signed, executed and, where necessary, verified or acknowledged, by the proper
person or persons.

                  Section 19. Merger or Consolidation of, or Change in Name of,
the Rights Agent.

                  (a) Any corporation into which the Rights Agent or any
successor Rights Agent may be merged or with which it may be consolidated, or
any corporation resulting from any merger or consolidation to which the Rights
Agent or any successor Rights Agent shall be a party, or any corporation
succeeding to the corporate trust or stock transfer business of the Rights Agent
or any successor Rights Agent, shall be the successor to the Rights Agent under
this Agreement without the execution or filing of any paper or any further act
on the part of any of the parties hereto, provided that such corporation would
be eligible for appointment as a successor Rights Agent under the provisions of
Section 21 hereof. In case at the time such successor Rights Agent shall succeed
to the agency created by this Agreement any of the Rights Certificates shall
have been countersigned but not delivered, any such successor Rights Agent may
adopt the countersignature of the predecessor Rights Agent and deliver such
Right Certificates so countersigned; and in case at that time any of the Right
Certificates shall not have been countersigned, any successor Rights Agent may
countersign such Right Certificates either in the name of the predecessor Rights
Agent or in the name of the successor Rights Agent; and in all such cases such
Right Certificates shall have the full force provided in the Right Certificates
and in this Agreement.

                  (b) In case at any time the name of the Rights Agent shall be
changed and at such time any of the Right Certificates shall have been
countersigned but not delivered, the Rights Agent may adopt the countersignature
under its prior name and deliver Right Certificates so countersigned; in case at

                                       28
<PAGE>

that time any of the Right Certificates shall not have been countersigned, the
Rights Agent may countersign such Right Certificates either in its prior name or
in its changed name; in all such cases such Right Certificates shall have the
full force provided in the Right Certificates and in this Agreement.

                  Section 20. Duties of Rights Agent. The Rights Agent
undertakes the duties and obligations imposed by this Agreement upon the
following terms and conditions, by all of which the Corporation and the holders
of Right Certificates by their acceptance thereof shall be bound:

                  (a) The Rights Agent may consult with legal counsel (who may
be an employee of or outside legal counsel for the Corporation or the Rights
Agent), and the opinion of such counsel shall be full and complete authorization
and protection to the Rights Agent as to any action taken or omitted by it in
good faith and in accordance with such opinion.

                  (b) Whenever in the performance of its duties under this
Agreement the Rights Agent shall deem it necessary or desirable that any fact or
matter be proved or established by the Corporation prior to taking or suffering
any action hereunder, such fact or matter (unless other evidence in respect
thereof be herein specifically prescribed) may be deemed to be conclusively
proved and established by a certificate signed by the Chairman of the Board, the
President or any Vice President and by the Treasurer or any Assistant Treasurer
or the Secretary or any Assistant Secretary of the Corporation and delivered to
the Rights Agent. Any such certificate shall be full authorization to the Rights
Agent for any action taken or suffered in good faith by it under the provisions
of this Agreement in reliance upon such certificate.

                  (c) The Rights Agent shall be liable hereunder only for its
own gross negligence, bad faith or willful misconduct.

                  (d) The Rights Agent shall not be liable for or by reason of
any of the statements of fact or recitals contained in this Agreement or in the
Right Certificates (except its countersignature thereof) or be required to
verify the same, but all such statements and recitals are and shall be deemed to
have been made by the Corporation only.

                  (e) The Rights Agent shall not be under any responsibility in
respect of the validity of this Agreement or the execution and delivery hereof
(except the due execution hereof by the Rights Agent) or in respect of the
validity or execution of any Right Certificate (except its countersignature
thereof); nor shall it be responsible for any breach by the Corporation of any
covenant or condition contained in this Agreement or in any Right Certificate;
nor shall it be responsible for any adjustment required under the provisions of
Section 11 or 13 hereof or responsible for the manner, method or amount of any
such adjustment or the ascertaining of the existence of facts that would require
any such adjustment (except with respect to the exercise of Rights evidenced by
Right Certificates after receipt of a certificate describing any such
adjustment); nor shall it by any act hereunder be deemed to make any

                                       29
<PAGE>

representation or warranty as to the authorization or reservation of any shares
of Preferred Stock or other security to be delivered pursuant to the exercise of
any Right or as to whether any shares of Preferred Stock or other security will,
when issued, be validly authorized and issued, fully paid and nonassessable.

                  (f) The Corporation agrees that it will perform, execute,
acknowledge and deliver or cause to be performed, executed, acknowledged and
delivered all such further and other acts, instruments and assurances as may
reasonably be required by the Rights Agent for the carrying out or performing by
the Rights Agent of the provisions of the Agreement.

                  (g) The Rights Agent is hereby authorized and directed to
accept instructions with respect to the performance of its duties hereunder from
the Chairman of the Board, the President or any Vice President or the Secretary
or the Treasurer of the Corporation, and to apply to such officers for advice or
instructions in connection with its duties, and it shall not be liable for any
action taken or suffered to be taken by it in good faith in accordance with
instructions of any such officer or for any delay in acting while waiting for
those instructions. Any application by the Rights Agent for written instructions
from the Corporation may, at the option of the Rights Agent, set forth in
writing any action proposed to be taken or omitted by the Rights Agent under
this Agreement and the date on and/or after which such action shall be taken or
such omission shall be effective. The Rights Agent shall not be liable for any
action taken by, or omission of, the Rights Agent in accordance with a proposal
included in any such application on or after the date specified in such
application (which date shall not be less than three Business Days after the
date any officer of the Corporation actually receives such application unless
any such officer shall have consented in writing to an earlier date) unless,
prior to taking any such action (or the effective date in the case of an
omission), the Rights Agent shall have received written instructions in response
to such application specifying the action to be taken or omitted.

                  (h) The Rights Agent and any shareholder, director, officer or
employee of the Rights Agent may buy, sell or deal in any of the Rights or other
securities of the Corporation or become pecuniarily interested in any
transaction in which the Corporation may be interested, or contract with or lend
money to the Corporation or otherwise act as fully and freely as though it were
not the Rights Agent under this Agreement. Nothing herein shall preclude the
Rights Agent from acting in any other capacity for the Corporation or for any
other legal entity.

                  (i) The Rights Agent may execute and exercise any of the
rights or powers hereby vested in it or perform any duty hereunder either itself
or by or through its attorneys or agents, and the Rights Agent shall not be
answerable or accountable for any act, default, neglect or misconduct of any
such attorneys or agents or for any loss to the Corporation resulting from any
such act, default, neglect or misconduct, provided reasonable care was exercised
in the selection and continued employment thereof.

                                       30
<PAGE>

                  (j) If, with respect to any Rights Certificate surrendered to
the Rights Agent for exercise or transfer, the certificate contained in the form
of assignment or the form of election to purchase set forth on the reverse
thereof, as the case may be, has not been completed to certify the holder is not
an Acquiring Person (or an Affiliate or Associate thereof), a Rights Agent shall
not take any further action with respect to such requested exercise or transfer
without first consulting with the Corporation.

                  Section 21. Change of Rights Agent. The Rights Agent or any
successor Rights Agent may resign and be discharged from its duties under this
Agreement upon 30 days' notice in writing mailed to the Corporation and to each
transfer agent of the Common Stock and the Preferred Stock by registered or
certified mail. The Corporation may remove the Rights Agent or any successor
Rights Agent (with or without cause) upon 30 days' notice in writing, mailed to
the Rights Agent or successor Rights Agent, as the case may be, and to each
transfer agent of the Common Stock and the Preferred Stock by registered or
certified mail. If the Rights Agent shall resign or be removed or shall
otherwise become incapable of acting, the Corporation shall appoint a successor
to the Rights Agent. If the Corporation shall fail to make such appointment
within a period of 30 days after such removal or after it has been notified in
writing of such resignation or incapacity by the resigning or incapacitated
Rights Agent or by the holder of a Right Certificate (who shall, with such
notice, submit his Right Certificate for inspection by the Corporation), then
the incumbent Rights Agent or the holder of record of any Right Certificate may
apply to any court of competent jurisdiction for the appointment of a new Rights
Agent. Any successor Rights Agent, whether appointed by the Corporation or by
such a court, shall be (a) a corporation organized and doing business under the
laws of the United States or of any state thereof, in good standing, which is
authorized under such laws to exercise corporate trust or stock transfer powers
and is subject to supervision or examination in the conduct of its corporate
trust or stock transfer business by federal or state authorities and which has
at the time of its appointment as Rights Agent a combined capital and surplus of
at least $50,000,000 or (b) an Affiliate controlled by or under common control
with one or more corporations described in clause (a) of this sentence. After
appointment, the successor Rights Agent shall be vested with the same powers,
rights, duties and responsibilities as if it had been originally named as Rights
Agent without further act or deed, but the predecessor Rights Agent shall
deliver and transfer to the successor Rights Agent any property at the time held
by it hereunder, and execute and deliver any further assurance, conveyance, act
or deed necessary for the purpose. Not later than the effective date of any such
appointment, the Corporation shall file notice thereof in writing with the
predecessor Rights Agent and each transfer agent of the Common Stock and
Preferred Stock, and mail a notice thereof in writing to the registered holders
of the Right Certificates. Failure to give any notice provided for in this
Section 21, however, or any defect therein, shall not affect the legality or
validity of the resignation or removal of the Rights Agent or the appointment of
the successor Rights Agent, as the case may be. Notwithstanding the foregoing
provisions, in the event of resignation, removal or incapacity of the Rights
Agent, the Corporation shall have the authority to act as the Rights Agent until
a successor Rights Agent shall have assumed the duties of the Rights Agent
hereunder.

                  Section 22. Issuance of New Right Certificates.
Notwithstanding any of the provisions of this Agreement or of the Rights to the
contrary, the Corporation may, at its option, issue new Right Certificates
evidencing Rights in such form as may be approved by its Board of Directors to
reflect any adjustment or change in the Exercise Price per share and the number
or kind or class of shares of stock or other securities or property purchasable
under the Right Certificates made in accordance with the provisions of this
Agreement. In addition, in connection with the issuance or sale of Voting Stock
following the Distribution Date and prior to the Expiration Date, the
Corporation may with respect to shares of Voting Stock so issued or sold
pursuant to (i) the exercise of stock options, (ii) under any employee plan or
arrangement, (iii) upon the exercise, conversion or exchange of securities,
notes or debentures issued by the Corporation or (iv) a contractual obligation
of the Corporation, in each case existing prior to the Distribution Date, issue
Rights Certificates representing the appropriate number of Rights in connection
with such issuance or sale.

                  Section 23. Redemption.

                  (a) The Corporation may, at its option, but only by the vote
of a majority of its Board of Directors, redeem all but not less than all of the
then outstanding Rights at any time prior to the Close of Business on the tenth
day following the Stock Acquisition Date (subject to extension by the
Corporation as provided in Section 26 hereof) at a redemption price of $0.01 per
Right, subject to adjustment as provided in Section 23(c) hereof (the
"Redemption Price"). The redemption of the Rights by the Board of Directors of
the Corporation may be made effective at such time after the Board's action to
redeem the Rights on such basis and subject to such conditions, as the Board of
Directors of the Corporation in its sole and absolute discretion may establish.
Notwithstanding anything contained in this Agreement to the contrary, the Rights
shall not be exercisable prior to the expiration of the Corporation's right of
redemption hereunder.

                  (b) Without any further action and without any notice, the
right to exercise the Rights will terminate effective at the time so designated
by action of the Board of Directors of the Corporation ordering the redemption
of the Rights and the only right thereafter of the holders of Rights shall be to
receive the Redemption Price. Within 10 days after the effective time of the
action of the Board of Directors of the Corporation ordering the redemption of
the Rights, the Corporation shall give notice of such redemption to the holders
of the then outstanding Rights by mailing such notice to all such holders at
their last addresses as they appear upon the registry books of the Rights Agent
or, prior to the Distribution Date, on the registry books of the transfer agent
for the Common Stock. Any notice which is mailed in the manner herein provided
shall be deemed given, whether or not the holder receives the notice. Each
notice of redemption will state the method by which the payment of the
Redemption Price will be made. At the option of the Board of Directors of the
Corporation, the Redemption Price may be paid in cash to each Rights holder or
by the issuance of shares (and, at the Corporation's election pursuant to
Section 14(b) hereof, cash or depositary receipts in lieu of fractions of shares
other than fractions which are integral multiples of one one-thousandth of a

                                       32
<PAGE>

share) of Preferred Stock or Common Stock having a Fair Market Value equal to
such cash payment.

                  (c) In the event the Corporation shall at any time after the
date of this Agreement but before the Close of Business on the tenth day
following the Stock Acquisition Date (A) pay any dividend on Common Stock in
shares of Common Stock, (B) subdivide or split the outstanding shares of Common
Stock into a greater number of shares or (C) combine or consolidate the
outstanding shares of Common Stock into a smaller number of shares or effect a
reverse split of the outstanding shares of Common Stock and as a consequence
thereof the number of Rights outstanding shall change, then, and in each such
event, the Redemption Price may, by action of the Board of Directors of the
Corporation in its discretion, be appropriately adjusted in respect of such
transaction so as to maintain the aggregate Redemption Price of all Rights after
such transaction at the same amount, insofar as practicable, as before the
transaction.

                  Section 24. Notice of Proposed Actions.

                  (a) In case the Corporation, after the Distribution Date,
shall propose (i) to effect any of the transactions referred to in Section
11(a)(i) hereof or to pay any dividend to the holders of record of its shares of
Common Stock payable in shares of capital stock of any class or to make any
other distribution to the holders of record of its Common Stock (other than a
regular periodic cash dividend at a rate not in excess of 150% of the rate of
the last cash dividend theretofore paid), or (ii) to offer to the holders of
record of its Common Stock options, warrants, or other rights to subscribe for
or to purchase shares of Common Stock (including any security convertible into
or exchangeable for Common Stock) or shares of stock of any class or any other
securities, options, warrants, convertible or exchangeable securities or other
rights, or (iii) to effect any reclassification of its Preferred Stock or Common
Stock or any recapitalization or reorganization of the Corporation, or (iv) to
effect any consolidation or merger with or into, or to effect any sale or other
transfer (or to permit one or more of its Subsidiaries to effect any sale or
other transfer), in one or more transactions, of more than 50% of the assets or
earning power of the Corporation and its Subsidiaries (taken as a whole) to, any
other Person or Persons, or (v) to effect the liquidation, dissolution or
winding up of the Corporation, then, in each such case, the Corporation shall
give to each holder of record of a Right Certificate, in accordance with Section
25 hereof, notice of such proposed action, which shall specify the record date
for the purposes of such transaction referred to in Section 11(a)(i) or such
dividend or distribution, or the date on which such reclassification,
recapitalization, reorganization, consolidation, merger, sale or transfer of
assets, liquidation, dissolution, or winding up is to take place and the record
date for determining participation therein by the holders of record of Common
Stock or Preferred Stock, if any such date is to be fixed, and such notice shall
be so given in the case of any action covered by clause (i) or (ii) above at
least 10 days prior to the record date for determining holders of record of the
Preferred Stock for purposes of such action, and in the case of any such other
action, at least 10 days prior to the date of the taking of such proposed action
or the date of participation therein by the holders of record of Common Stock or
Preferred Stock, whichever shall be the earlier. The failure to give notice
required by this Section 24 or any defect therein shall not affect the legality

                                       33
<PAGE>

or validity of the action taken by the Corporation or the vote upon any such
action.

                  (b) In case the event referred to in Section 11(a)(ii) hereof
shall occur, then the Corporation shall as soon as practicable thereafter, in
accordance with Section 25 hereof, give to each holder of a Right notice of the
occurrence of such event, which notice shall describe the event and the
consequences of the event to holders of Rights under Section 11(a)(ii) hereof.

                  Section 25. Notices. Notices or demands authorized by this
Agreement to be given or made by the Rights Agent or by the holder of record of
any Right Certificate or Right to or on the Corporation shall be in writing and
shall be considered given upon receipt or seven Business Days after being sent
by first-class mail, postage prepaid, in any case addressed (until another

                  Section 26. Supplements and Amendments. For as long as the
Rights are then redeemable and except as provided in the last sentence of this
Section 26, the Corporation may, in its sole and absolute discretion, and the
Rights Agent shall if the Corporation so directs, supplement or amend any
provision of this Agreement without the approval of any holders of the Rights.
At any time when the Rights are not then redeemable and except as provided in
the last sentence of this Section 26, the Corporation may, and the Rights Agent
shall if the Corporation so directs, supplement or amend this Agreement without

                                       34
<PAGE>

the approval of any holders of Right Certificates (i) to cure any ambiguity,
(ii) to correct or supplement any provision contained herein which may be
defective or inconsistent with any other provisions herein or (iii) to change or
supplement the provisions hereunder in any manner which the Corporation may deem
necessary or desirable, provided that no such supplement or amendment pursuant
to this clause (iii) shall materially adversely affect the interest of the
holders of Right Certificates (other than an Acquiring Person or any other
Person in whose hands Rights are null and void under the provisions of Section
7(e) hereof). Upon the delivery of a certificate from an appropriate officer of
the Corporation which states that the proposed supplement or amendment is in
compliance with the terms of this Section 26, the Rights Agent shall execute
such supplement or amendment. Notwithstanding anything contained in this
Agreement to the contrary, no supplement or amendment shall be made which
changes the Redemption Price; it being understood that an adjustment of the
Redemption Price in accordance with Section 23 shall not be considered a
supplement or amendment of this Agreement.

                  Section 27. Exchange.

                  (a) The Board of Directors of the Corporation may, at its
option, at any time after any Person becomes an Acquiring Person, exchange all
or part of the then outstanding and exercisable Rights (which shall not include
Rights that have become null and void pursuant to the provisions of Section 7(e)
hereof) by exchanging for each such Right a number of shares of Common Stock
having an aggregate Fair Market Value on the date such Person became an
Acquiring Person equal to the Spread, appropriately adjusted to reflect any
stock split, stock dividend or similar transaction occurring after the date
hereof (such number of shares of Common Stock per Right being hereinafter
referred to as the "Exchange Ratio"). Notwithstanding the foregoing, the Board
of Directors of the Corporation shall not be empowered to effect such exchange
at any time after any Person (other than an Exempt Person), together with all
Affiliates and Associates of such Person, becomes the Beneficial Owner of 50% or
more of the Voting Stock then outstanding. From and after the occurrence of an
event specified in Section 13(a) hereof, any Rights that theretofore have not
been exchanged pursuant to this Section 27(a) shall thereafter be exercisable
only in accordance with Section 13 and may not be exchanged pursuant to this
Section 27(a).

                  (b) Immediately upon the action of the Board of Directors of
the Corporation ordering the exchange of any Rights pursuant to paragraph (a) of
this Section 27 and without any further action and without any notice, the right
to exercise such Rights shall terminate and the only right thereafter of a
holder of such Rights shall be to receive that number of shares of Common Stock
equal to the number of such Rights held by such holder multiplied by the
Exchange Ratio. The Corporation shall promptly give public notice of any such
exchange; provided, however, that the failure to give, or any defect in, such
notice shall not affect the validity of such exchange. The Corporation promptly
shall mail a notice of any such exchange to all of the holders of such Rights at
their last addresses as they appear upon the registry books of the Rights Agent.
Any notice which is mailed in the manner herein provided shall be deemed given,
whether or not the holder receives the notice. Each such notice of exchange will

                                       35
<PAGE>

state the method by which the exchange of the shares of Common Stock for Rights
will be effected and, in the event of any partial exchange, the number of Rights
which will be exchanged. Any partial exchange shall be effected pro rata based
on the number of Rights (other than Rights which have become null and void
pursuant to the provisions of Section 7(e) hereof) held by each holder of
Rights.

                  (c) In the event that there shall not be sufficient shares of
Common Stock issued but not outstanding or authorized but unissued to permit any
exchange of Rights as contemplated in accordance with this Section 27, the
Corporation shall substitute to the extent of such insufficiency, for each share
of Common Stock that would otherwise be issuable upon exchange of a Right, a
number of shares of Preferred Stock or fractions thereof having an aggregate
Fair Market Value equal to the Fair Market Value of one share of Common Stock as
of the date any Person becomes an Acquiring Person.

                  (d) The Corporation shall not be required to issue fractions
of shares of Common Stock or to distribute certificates which evidence
fractional shares. In lieu of such fractional shares, the Corporation shall pay
to the registered holders of the Right Certificates with regard to which such
fractional shares of Common Stock would otherwise be issuable an amount in cash
equal to the same fraction of the current market value of a whole share of
Common Stock. For the purposes of this paragraph (d), the current market value
of a whole share of Common Stock shall be the closing price of a share of Common
Stock for the Trading Day immediately prior to the date of exchange pursuant to
this Section 27.

                  Section 28. Successors. All of the covenants and provisions of
this Agreement by or for the benefit of the Corporation or the Rights Agent
shall bind and inure to the benefit of their respective successors and assigns
hereunder.

                  Section 29. Benefits of this Agreement. Nothing in this
Agreement shall be construed to give to any Person other than the Corporation,
the Rights Agent and the registered holders of the Right Certificates (and,
prior to the Distribution Date, the holders of Common Stock in their capacity as
holders of the Rights) any legal or equitable right, remedy or claim under this
Agreement; but this Agreement shall be for the sole and exclusive benefit of the
Corporation, the Rights Agent and the holders of record of the Right
Certificates (and, prior to the Distribution Date, the holders of Common Stock
in their capacity as holders of the Rights).

                  Section 30. Delaware Contract. This Agreement and each Right
Certificate issued hereunder shall be deemed to be a contract made under the
laws of the State of Delaware and for all purposes shall be governed by and
construed and enforced in accordance with the laws of such state applicable to
contracts to be made and performed entirely within such state.

                  Section 31. Counterparts. This Agreement may be executed in
any number of counterparts and each of such counterparts shall for all purposes

                                       36
<PAGE>

be deemed to be an original, and all such counterparts shall together constitute
but one and the same instrument.

                  Section 32. Descriptive Headings. Descriptive headings of the
several Sections of this Agreement are inserted for convenience only and shall
not control or affect the meaning or construction of any of the provisions
hereof.

                  Section 33. Severability. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction or
other authority to be invalid, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated.

                  Section 34. Determinations and Actions by the Board of
Directors. The Board of Directors of the Corporation shall have the exclusive
power and authority to administer, interpret and apply this Agreement and to
exercise the rights and powers specifically granted to the Board of Directors of
the Corporation or to the Corporation by this Agreement or by law and may take
such action as may be necessary or advisable in the administration of this
Agreement or to amend or supplement this Agreement in accordance with its terms,
including, without limitation, the right and power (i) to make all
determinations deemed necessary or advisable for the administration of this
Agreement, (ii) to decide to redeem the Rights and (iii) to decide to amend or
supplement this Agreement. All such actions, calculations, interpretations and
determinations (including any decision not to take any action) done or made by
the Board of Directors of the Corporation in good faith shall (x) be final,
conclusive and binding on the Corporation, the Rights Agent, the holders of the
Rights, as such, and all other Persons and (y) not subject any member of the
Board of Directors of the Corporation to any liability to the holders of Rights.

                          SUMMARY OF RIGHTS TO PURCHASE
                  SERIES A JUNIOR PARTICIPATING PREFERRED STOCK

                  On July 19, 2002, the Board of Directors of IMPATH Inc., a
Delaware corporation (the "Corporation"), declared a dividend distribution of
one Preferred Stock Purchase Right for each outstanding share of common stock,
par value $0.005 per share (the "Common Stock"), of the Corporation. The
distribution was made payable as of August 1, 2002 to stockholders of record on
that date (the "Record Date"). Each Right, once exercisable, entitles the
registered holder to purchase from the Corporation one one-thousandth (1/1,000)
of a share of preferred stock of the Corporation, designated as Series A Junior
Participating Preferred Stock (the "Preferred Stock"), at a price of $140.00 per
one one-thousandth (1/1,000) of a share ("Exercise Price"), subject to certain
adjustments. The description and terms of the Rights are set forth in a Rights
Agreement (the "Rights Agreement") by and between the Corporation and American
Stock Transfer & Trust Company, as Rights Agent (the "Rights Agent").

                  As discussed below, initially the Rights will not be
                  ----------------------------------------------------
exercisable, certificates will not be sent to stockholders and the Rights will
------------------------------------------------------------------------------
automatically trade with the Common Stock.
------------------------------------------

                  The Rights, unless earlier redeemed by the Board of Directors,
become exercisable upon the close of business on the day (the "Distribution
Date") which is the earlier of (i) the tenth day following a public announcement
that a person or group of affiliated or associated persons, with certain
exceptions set forth below, has acquired beneficial ownership of 15% or more of
the outstanding voting stock of the Corporation (an "Acquiring Person") and (ii)
the tenth business day (or such later date as may be determined by the Board of
Directors prior to such time as any person or group of affiliated or associated
persons becomes an Acquiring Person) after the date of the commencement by any
person of a tender or exchange offer, the consummation of which would result in
such person or group of affiliated or associated persons becoming an Acquiring
Person.

                  An Acquiring Person does not include (A) the Corporation, (B)
any subsidiary of the Corporation, (C) any employee benefit plan or employee
stock plan of the Corporation or of any subsidiary of the Corporation, or any

<PAGE>

trust or other entity organized, appointed, established or holding voting stock
for or pursuant to the terms of any such plan (D) any person or group of
affiliated or associated persons whose ownership of 15% or more of the shares of
voting stock of the Corporation then outstanding results solely from (i) any
action or transaction or transactions approved by the Board of Directors before
such person or group became an Acquiring Person or (ii) a reduction in the
number of issued and outstanding shares of voting stock of the Corporation
pursuant to a transaction or transactions approved by the Board of Directors
(provided that any person or group that does not become an Acquiring Person by
reason of clause (i) or (ii) above shall become an Acquiring Person upon
acquisition of an additional 1% or more of the Corporation's voting stock unless
such acquisition of additional voting stock would not result in such person
becoming an Acquiring Person by reason of clause (i) or (ii) above), or (E) any
person who, as of July 19, 2002, together with all affiliates and associates of
such person, was the beneficial owner of 15% or more of the voting stock of the
Corporation outstanding as of such date; provided, however, that any person
described in this clause (E) shall become an Acquiring Person if (i) if such
person, together with all affiliates and associates of such person, after July
19, 2002, acquires beneficial ownership of an additional 1% or more of the
voting stock (unless such acquisition is pursuant to a transaction described in
clause (D)(i) or (D)(ii) above) or (ii) such person, together with all
affiliates and associates of such person, after July 19, 2002, reduces its
beneficial ownership of the voting stock to less than 15% of the outstanding
voting stock and thereafter becomes the beneficial owner of 15% or more of the
outstanding voting stock (unless such acquisition is pursuant to a transaction
described in clause (D)(i) or (D)(ii) above).

                  Prior to the Distribution Date, the Rights will not be
exercisable, will not be represented by a separate certificate, and will not be
transferable apart from the Corporation's Common Stock, but will instead be
evidenced, with respect to any of the Common Stock certificates outstanding as
of the Record Date, by such Common Stock certificate with a copy of this Summary
of Rights attached thereto. Until the Distribution Date (or earlier redemption,
exchange or expiration of the Rights), new Common Stock certificates issued
after the Record Date will contain a legend incorporating the Rights Agreement
by reference. Until the Distribution Date (or earlier redemption, exchange or
expiration of the Rights), the surrender for transfer of any of the Common Stock
certificates outstanding as of the Record Date, with or without a copy of this
Summary of Rights attached thereto, will also constitute the transfer of the
Rights associated with the Common Stock represented by such certificate. As soon
as practicable following the Distribution Date, separate certificates evidencing
the Rights ("Right Certificates") will be mailed to holders of record of the
Common Stock as of the close of business on the Distribution Date, and such
separate certificates alone will evidence the Rights from and after the
Distribution Date.

                  The Rights are not exercisable until the Distribution Date.
The Rights will expire at the close of business on July 19, 2012, unless earlier
redeemed or exchanged by the Corporation as described below.

                  Shares of Preferred Stock purchasable upon exercise of the
Rights will be non-redeemable and, unless otherwise provided in connection with
the creation of a subsequent series of preferred stock, will be subordinate to
any other series of the Corporation's preferred stock. The Preferred Stock may
not be issued except upon exercise of Rights. Each share of Preferred Stock will

                                       2
<PAGE>

be entitled to receive when, as and if declared, a quarterly dividend in an
amount equal to the greater of $10.00 per share or 1,000 times the cash
dividends declared on the Corporation's Common Stock. In addition, the holders
of the Preferred Stock are entitled to receive 1,000 times any non-cash
dividends (other than dividends payable in equity securities) declared on the
Common Stock, in like kind. In the event of the liquidation of the Corporation,
the holders of Preferred Stock will be entitled to receive, for each share of
Preferred Stock, a payment in an amount equal to the greater of $140,000.00 or
1,000 times the payment made per share of Common Stock. Each share of Preferred
Stock will have 1,000 votes, voting together with the Common Stock. In the event
of any merger, consolidation or other transaction in which Common Stock is
exchanged, each share of Preferred Stock will be entitled to receive 1,000 times
the amount received per share of Common Stock. The rights of Preferred Stock as
to dividends, liquidation and voting are protected by anti-dilution provisions.

                  The Exercise Price of the Rights and the number of shares of
Preferred Stock issuable upon exercise of the Rights are subject to certain
adjustments from time to time in the event of a stock dividend on, or a
subdivision or combination of, the Common Stock. The Exercise Price for the
Rights also is subject to adjustment in the event of extraordinary distributions
of cash or other property to holders of Common Stock.

                  Unless the Rights are earlier redeemed, in the event that a
person or group becomes an Acquiring Person, the Rights Agreement provides that
proper provisions will be made so that each holder of record of a Right (other
than Rights beneficially owned by an Acquiring Person and certain affiliates,
associates and transferees thereof, whose Rights will thereupon become null and
void), will thereafter have the right to receive, upon payment of the Exercise
Price, that number of shares of the Preferred Stock having a fair market value
determined in accordance with the Rights Agreement at the time of the
transaction equal to approximately two times the Exercise Price (such value to
be determined with reference to the fair market value of the Corporation's
Common Stock as provided in the Rights Agreement).

                  In addition, unless the Rights are earlier redeemed or
exchanged, in the event that, after the time that a person or group becomes an
Acquiring Person, the Corporation were to be acquired in a merger or other
business combination (in which any shares of Common Stock are changed into or
exchanged for other securities or assets) or more than 50% of the assets or
earning power of the Corporation and its subsidiaries (taken as a whole) were to
be sold or transferred in one or a series of related transactions, the Rights
Agreement provides that proper provision will be made so that each holder of
record of a Right (other than Rights beneficially owned by an Acquiring Person
and certain affiliates, associates and transferees thereof, whose Rights will
thereupon become null and void) will from and after such date have the right to
receive, upon payment of the Exercise Price, that number of shares of common
stock of the acquiring company having a fair market value at the time of such
transaction determined in accordance with the Rights Agreement equal to
approximately two times the Exercise Price.

                  At any time after any person or group becomes an Acquiring
Person and prior to the acquisition by such person or group of 50% or more of
the outstanding voting stock, the Board of Directors of the Corporation may
exchange the Rights (other than Rights owned by such person or group which will
have become null and void), in whole or in part, for that number of shares of
the Corporation's Common Stock having a fair market value on the date such
person or group became an Acquiring Person equal to the excess of (i) the fair

                                       3
<PAGE>

market value of Preferred Stock issuable upon the exercise of the Rights over
(ii) the Exercise Price of the Rights, in each case subject to anti-dilution
adjustments.

                  Fractions of shares of Preferred Stock (other than fractions
which are integral multiples of one one-thousandth of a share) may, at the
election of the Corporation, be evidenced by depositary receipts. The
Corporation may also issue cash in lieu of fractional shares which are not
integral multiples of one one-thousandth of a share.

                  At any time prior to the close of business on the tenth day
after there has been a public announcement that a person has become an Acquiring
Person, the Corporation may redeem the Rights in whole, but not in part, at a
price of $0.01 per Right (the "Redemption Price"). Immediately upon the
effective time of the action of the Board of Directors of the Corporation
authorizing redemption of the Rights, the right to exercise the Rights will
terminate and the only right of the holders of Rights will be to receive the
Redemption Price.

                  For as long as the Rights are then redeemable, the Corporation
may, except with respect to the Redemption Price, amend the Rights in any
manner, including an amendment to extend the time period in which the Rights may
be redeemed. At any time when the Rights are not then redeemable, the
Corporation may amend the Rights in any manner that does not materially
adversely affect the interests of holders of the Rights as such.

                  Until a Right is exercised, the holder, as such, will have no
rights as a stockholder of the Corporation, including, without limitation, the
right to vote or to receive dividends.

                  A copy of the Rights Agreement has been filed with the
Securities and Exchange Commission on July __, 2002, as an Exhibit to the
Corporation's Current Report on Form 8-K. A copy of the Rights Agreement is
available free of charge from the Corporation. This summary description of the
Rights does not purport to be complete and is qualified in its entirety by
reference to the Rights Agreement which is incorporated in this summary
description herein by reference.

                  As provided in the Rights Agreement, the Exercise Price and
the number of shares of Preferred Stock which may be purchased upon the exercise

                  SERIES A JUNIOR PARTICIPATING PREFERRED STOCK

                                   IMPATH INC.

                     Pursuant to Section 151 of the Delaware
                             General Corporation Law

                  I, Richard C. Rosenzweig, the Corporate Secretary of IMPATH
Inc., a corporation organized and existing under the Delaware General
Corporation Law (the "Corporation"), in accordance with the provisions of
Section 151 of such law, DO HEREBY CERTIFY that pursuant to the authority
conferred upon the Board of Directors of the Corporation by the Restated
Certificate of Incorporation of the Corporation, the Board of Directors on July
19, 2002 adopted the following resolution which creates a series of 60,000
shares of Preferred Stock designated as Series A Junior Participating Preferred
Stock as follows:
                  RESOLVED, that pursuant to Section 151(g) of the Delaware
General Corporation Law and the authority vested in the Board of Directors of
the Corporation in accordance with the provisions of ARTICLE FOURTH of the
Restated Certificate of Incorporation of the Corporation, a series of Preferred
Stock of the Corporation be, and hereby is, created and the powers,
designations, preferences and relative, participating, optional or other special
rights of the shares of such series, and the qualifications, limitations or
restrictions thereof, be, and hereby are, as follows:

<PAGE>

                  Section 1. Designation and Amount. The shares of such series
shall be designated as "Series A Junior Participating Preferred Stock" (the
"Series A Preferred Stock") and the number of shares constituting such series
shall be 60,000.

                  Section 2. Dividends and Distributions.

                  (A) Subject to the provisions for adjustment hereinafter set
forth, and subject to the rights of the holders of any shares of any series of
Preferred Stock of the Corporation ranking prior and superior to the Series A
Preferred Stock with respect to dividends, the holders of shares of Series A
Preferred Stock shall be entitled to receive, when, as and if declared by the
Board of Directors of the Corporation out of funds legally available for the
purpose, (i) cash dividends in an amount per share (rounded to the nearest cent)
equal to 1,000 times the aggregate per share amount of all cash dividends
declared or paid on the Common Stock, $0.005 par value per share, of the
Corporation (the "Common Stock") and (ii) a preferential cash dividend (the
"Preferential Dividends"), if any, in preference to the holders of Common Stock,
on the first business day of April, July, October and January, of each year
(each a "Quarterly Dividend Payment Date"), commencing on the first Quarterly
Dividend Payment Date after the first issuance of a share or fraction of a share
of Series A Preferred Stock, payable in an amount (except in the case of the
first Quarterly Dividend Payment Date if the date of the first issuance of
Series A Preferred Stock is a date other than a Quarterly Dividend Payment Date,
in which case such payment shall be a prorated portion of such amount) equal to
$10.00 per share of Series A Preferred Stock less the per share amount of all
cash dividends declared on the Series A Preferred Stock pursuant to clause (i)
of this sentence since the immediately preceding Quarterly Dividend Payment Date
or, with respect to the first Quarterly Dividend Payment Date, since the first
issuance of any share or fraction of a share of Series A Preferred Stock. In the
event the Corporation shall, at any time after the issuance of any share or
fraction of a share of Series A Preferred Stock, make any distribution on the
shares of Common Stock, whether by way of a dividend or a reclassification of
stock, a recapitalization, reorganization or partial liquidation of the
Corporation or otherwise, which is payable in cash or any debt security, debt
instrument, real or personal property or any other property (other than cash
dividends subject to the immediately preceding sentence, a distribution of
shares of Common Stock or other capital stock of the Corporation or a
distribution of options, rights or warrants to acquire any such share, including
any debt security convertible into or exchangeable for any such share, at a
price less than the Fair Market Value (as hereinafter defined) of such share of
Common Stock), then, and in each such event, the Corporation shall
simultaneously pay on each then outstanding share of Series A Preferred Stock a
distribution, in like kind, of 1,000 times such distribution paid on a share of
Common Stock (subject to the provisions for adjustment hereinafter set forth).
The dividends and distributions on the Series A Preferred Stock to which holders
thereof are entitled pursuant to clause (i) of the first sentence of this
paragraph and pursuant to the second sentence of this paragraph are hereinafter
referred to as "Dividends" and the multiple of such cash and non-cash dividends
on the Common Stock applicable to the determination of the Dividends, which
shall be 1,000 initially but shall be adjusted from time to time as hereinafter
provided, is hereinafter referred to as the "Dividend Multiple". In the event
the Corporation shall at any time after July 19, 2002 (the "Effective Date")
declare or pay any dividend or make any distribution on Common Stock payable in

                                       2
<PAGE>

shares of Common Stock, or effect a subdivision or split or a combination,
consolidation or reverse split of the outstanding shares of Common Stock into a
greater or lesser number of shares of Common Stock, then in each such case the
Dividend Multiple thereafter applicable to the determination of the amount of
Dividends which holders of shares of Series A Preferred Stock shall be entitled
to receive shall be the Dividend Multiple applicable immediately prior to such
event multiplied by a fraction the numerator of which is the number of shares of
Common Stock outstanding immediately after such event and the denominator of
which is the number of shares of Common Stock that were outstanding immediately
prior to such event.

                  (B) The Corporation shall declare each Dividend at the same
time it declares any cash or non-cash dividend or distribution on the Common
Stock in respect of which a Dividend is required to be paid. No cash or non-cash
dividend or distribution on the Common Stock in respect of which a Dividend is
required to be paid shall be paid or set aside for payment on the Common Stock
unless a Dividend in respect of such dividend or distribution on the Common
Stock shall be simultaneously paid or set aside for payment (as the case may
be), on the Series A Preferred Stock.

                  (C) Preferential Dividends shall begin to accrue on
outstanding shares of Series A Preferred Stock from the Quarterly Dividend
Payment Date next preceding the date of issuance of any shares of Series A
Preferred Stock. Accrued but unpaid Preferential Dividends shall cumulate but
shall not bear interest. Preferential Dividends paid on the shares of Series A
Preferred Stock in an amount less than the total amount of such dividends at the
time accrued and payable on such shares shall be allocated pro rata on a
share-by-share basis among all such shares at the time outstanding.

                  Section 3. Voting Rights. The holders of shares of Series A
Preferred Stock shall have the following voting rights:

                  (A) Subject to the provisions for adjustment hereinafter set
forth, each share of Series A Preferred Stock shall entitle the holder thereof
to 1,000 votes on all matters submitted to a vote of the holders of the Common
Stock. The number of votes which a holder of Series A Preferred Stock is
entitled to cast, as the same may be adjusted from time to time as hereinafter
provided, is hereinafter referred to as the "Vote Multiple". In the event the
Corporation shall at any time after the Effective Date declare or pay any
dividend on Common Stock payable in shares of Common Stock, or effect a
subdivision or split or a combination, consolidation or reverse split of the
outstanding shares of Common Stock into a greater or lesser number of shares of
Common Stock, then in each such case the Vote Multiple thereafter applicable to
the determination of the number of votes per share to which holders of shares of
Series A Preferred Stock shall be entitled after such event shall be the Vote
Multiple immediately prior to such event multiplied by a fraction the numerator
of which is the number of shares of Common Stock outstanding immediately after
such event and the denominator of which is the number of shares of Common Stock
that were outstanding immediately prior to such event.

                                       3
<PAGE>

                  (B) Except as otherwise provided herein, in the Restated
Certificate of Incorporation or by law, the holders of shares of Series A
Preferred Stock and the holders of shares of Common Stock shall vote together as
one class on all matters submitted to a vote of stockholders of the Corporation.

                  (C) In the event that the Preferential Dividends accrued on
the Series A Preferred Stock for four or more quarterly dividend periods,
whether consecutive or not, shall not have been declared and paid or irrevocably
set aside for payment, the holders of record of Preferred Stock of the
Corporation of all series (including the Series A Preferred Stock), other than
any series in respect of which such right is expressly withheld by the Restated
Certificate of Incorporation or the authorizing resolutions included in any
certificate of designations therefor, shall have the right, at the next meeting
of stockholders called for the election of directors, to elect two members to
the Board of Directors of the Corporation, which directors shall be in addition
to the number required prior to such event, to serve until the next annual
meeting and until their successors are elected and qualified or their earlier
resignation, removal or incapacity or until such earlier time as all accrued and
unpaid Preferential Dividends upon the outstanding shares of Series A Preferred
Stock shall have been paid (or irrevocably set aside for payment) in full. The
holders of shares of Series A Preferred Stock shall continue to have the right
to elect directors as provided by the immediately preceding sentence until all
accrued and unpaid Preferential Dividends upon the outstanding shares of Series
A Preferred Stock shall have been paid (or set aside for payment) in full. Such
directors may be removed and replaced by such stockholders, and vacancies in
such directorships may be filled only by such stockholders (or by the remaining
director elected by such stockholders, if there be one) in the manner permitted
by law; provided, however, that any such action by stockholders shall be taken
at a meeting of stockholders and shall not be taken by written consent thereto.

                  (D) Except as otherwise required by the Restated Certificate
of Incorporation or by law or set forth herein, holders of Series A Preferred
Stock shall have no other special voting rights and their consent shall not be
required (except to the extent they are entitled to vote with holders of Common
Stock as set forth herein) for the taking of any corporate action.

                  Section 4. Certain Restrictions.

                  (A) Whenever Preferential Dividends or Dividends are in
arrears or the Corporation shall be in default of payment thereof, thereafter
and until all accrued and unpaid Preferential Dividends and Dividends, whether
or not declared, on shares of Series A Preferred Stock outstanding shall have
been paid or set irrevocably aside for payment in full, and in addition to any
and all other rights which any holder of shares of Series A Preferred Stock may
have in such circumstances, the Corporation shall not:

                           (i) declare or pay dividends on, make any other
                  distributions on, or redeem or purchase or otherwise acquire
                  for consideration, any shares of stock ranking junior (either
                  as to dividends or upon liquidation, dissolution or winding
                  up) to the Series A Preferred Stock;

                                       4
<PAGE>

                           (ii) declare or pay dividends on or make any other
                  distributions on any shares of stock ranking on a parity as to
                  dividends with the Series A Preferred Stock, unless dividends
                  are paid ratably on the Series A Preferred Stock and all such
                  parity stock on which dividends are payable or in arrears in
                  proportion to the total amounts to which the holders of all
                  such shares are then entitled if the full dividends accrued
                  thereon were to be paid;

                           (iii) except as permitted by subparagraph (iv) of
                  this Section 4(A), redeem or purchase or otherwise acquire for
                  consideration shares of any stock ranking on a parity (either
                  as to dividends or upon liquidation, dissolution or winding
                  up) with the Series A Preferred Stock, provided that the
                  Corporation may at any time redeem, purchase or otherwise
                  acquire shares of any such parity stock in exchange for shares
                  of any stock of the Corporation ranking junior (both as to
                  dividends and upon liquidation, dissolution or winding up) to
                  the Series A Preferred Stock; or

                           (iv) purchase or otherwise acquire for consideration
                  any shares of Series A Preferred Stock, or any shares of stock
                  ranking on a parity with the Series A Preferred Stock (either
                  as to dividends or upon liquidation, dissolution or winding
                  up), except in accordance with a purchase offer made to all
                  holders of such shares upon such terms as the Board of
                  Directors of the Corporation, after consideration of the
                  respective annual dividend rates and other relative rights and
                  preferences of the respective series and classes, shall
                  determine in good faith will result in fair and equitable
                  treatment among the respective series or classes.

                  (B) The Corporation shall not permit any Subsidiary (as
hereinafter defined) of the Corporation to purchase or otherwise acquire for
consideration any shares of stock of the Corporation unless the Corporation
could, under paragraph (A) of this Section 4, purchase or otherwise acquire such
shares at such time and in such manner. A "Subsidiary" of the Corporation shall
mean any corporation or other entity of which securities or other ownership
interests having ordinary voting power sufficient to elect a majority of the
board of directors of such corporation or other entity or other persons
performing similar functions are beneficially owned, directly or indirectly, by
the Corporation or by any corporation or other entity that is otherwise
controlled by the Corporation.

                  (C) The Corporation shall not issue any shares of Series A
Preferred Stock except upon exercise of Rights issued pursuant to that certain
Rights Agreement dated as of July 19, 2002, by and between the Corporation and
American Stock Transfer & Trust Company, as Rights Agent, as it may be amended
from time to time, a copy of which is on file with the Secretary of the
Corporation at its principal executive office and shall be made available to
stockholders of record without charge upon written request therefor addressed to
said Secretary. Notwithstanding the foregoing sentence, nothing contained in the
provisions of this Certificate of Designations shall prohibit or restrict the
Corporation from issuing for any purpose any series of Preferred Stock with

                                       5
<PAGE>

rights and privileges similar to, different from, or greater than, those of the
Series A Preferred Stock.

                  Section 5. Reacquired Shares. Any shares of Series A Preferred
Stock purchased or otherwise acquired by the Corporation in any manner
whatsoever shall be retired and cancelled promptly after the acquisition
thereof. All such shares upon their retirement and cancellation shall become
authorized but unissued shares of Preferred Stock, without designation as to
series, and such shares may be reissued as part of a new series of Preferred
Stock to be created by resolution or resolutions of the Board of Directors of
the Corporation.

                  Section 6. Liquidation, Dissolution or Winding Up. Upon any
voluntary or involuntary liquidation, dissolution or winding up of the
Corporation, no distribution shall be made (i) to the holders of shares of stock
ranking junior (either as to dividends or upon liquidation, dissolution or
winding up) to the Series A Preferred Stock unless the holders of shares of
Series A Preferred Stock shall have received for each share of Series A
Preferred Stock, subject to adjustment as hereinafter provided, (A) $140,000.00
plus an amount equal to accrued and unpaid dividends and distributions thereon,
whether or not declared, to the date of such payment or, (B) if greater than the
amount specified in clause (i)(A) of this sentence, an amount equal to 1,000
times the aggregate amount to be distributed per share to holders of Common
Stock, as the same may be adjusted as hereinafter provided and (ii) to the
holders of stock ranking on a parity upon liquidation, dissolution or winding up
with the Series A Preferred Stock, unless simultaneously therewith distributions
are made ratably on the Series A Preferred Stock and all other shares of such
parity stock in proportion to the total amounts to which the holders of shares
of Series A Preferred Stock are entitled under clause (i)(A) of this sentence
and to which the holders of such parity shares are entitled, in each case upon
such liquidation, dissolution or winding up. The amount to which holders of
Series A Preferred Stock may be entitled upon liquidation, dissolution or
winding up of the Corporation pursuant to clause (i)(B) of the foregoing
sentence is hereinafter referred to as the "Participating Liquidation Amount"
and the multiple of the amount to be distributed to holders of shares of Common
Stock upon the liquidation, dissolution or winding up of the Corporation
applicable pursuant to said clause to the determination of the Participating
Liquidation Amount, as said multiple may be adjusted from time to time as
hereinafter provided, is hereinafter referred to as the "Liquidation Multiple".
In the event the Corporation shall at any time after the Effective Date declare
or pay any dividend on Common Stock payable in shares of Common Stock, or effect
a subdivision or split or a combination, consolidation or reverse split of the
outstanding shares of Common Stock into a greater or lesser number of shares of
Common Stock, then, in each such case, the Liquidation Multiple thereafter
applicable to the determination of the Participating Liquidation Amount to which
holders of Series A Preferred Stock shall be entitled after such event shall be
the Liquidation Multiple applicable immediately prior to such event multiplied
by a fraction the numerator of which is the number of shares of Common Stock
outstanding immediately after such event and the denominator of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

                  Section 7. Certain Reclassifications and Other Events.

                  (A) In the event that holders of shares of Common Stock
receive after the Effective Date in respect of their shares of Common Stock any
share of capital stock of the Corporation (other than any share of Common
Stock), whether by way of reclassification, recapitalization, reorganization,
dividend or other distribution or otherwise (a "Transaction"), then, and in each
such event, the dividend rights, voting rights and rights upon the liquidation,
dissolution or winding up of the Corporation of the shares of Series A Preferred
Stock shall be adjusted so that after such event the holders of Series A
Preferred Stock shall be entitled, in respect of each share of Series A
Preferred Stock held, in addition to such rights in respect thereof to which
such holder was entitled immediately prior to such adjustment, to (i) such
additional dividends as equal the Dividend Multiple in effect immediately prior
to such Transaction multiplied by the additional dividends which the holder of a
share of Common Stock shall be entitled to receive by virtue of the receipt in
the Transaction of such capital stock, (ii) such additional voting rights as
equal the Vote Multiple in effect immediately prior to such Transaction
multiplied by the additional voting rights which the holder of a share of Common
Stock shall be entitled to receive by virtue of the receipt in the Transaction
of such capital stock and (iii) such additional distributions upon liquidation,
dissolution or winding up of the Corporation as equal the Liquidation Multiple
in effect immediately prior to such Transaction multiplied by the additional
amount which the holder of a share of Common Stock shall be entitled to receive
upon liquidation, dissolution or winding up of the Corporation by virtue of the
receipt in the Transaction of such capital stock, as the case may be, all as
provided by the terms of such capital stock.

                  (B) In the event that holders of shares of Common Stock
receive after the Effective Date in respect of their shares of Common Stock any
right or warrant to purchase Common Stock (including as such a right, for all
purposes of this paragraph, any security convertible into or exchangeable for
Common Stock) at a purchase price per share less than the Fair Market Value of a
share of Common Stock on the date of issuance of such right or warrant, then and
in each such event the dividend rights, voting rights and rights upon the
liquidation, dissolution or winding up of the Corporation of the shares of
Series A Preferred Stock shall each be adjusted so that after such event the
Dividend Multiple, the Vote Multiple and the Liquidation Multiple shall each be
the product of the Dividend Multiple, the Vote Multiple and the Liquidation
Multiple, as the case may be, in effect immediately prior to such event
multiplied by a fraction the numerator of which shall be the number of shares of
Common Stock outstanding immediately before such issuance of rights or warrants
plus the maximum number of shares of Common Stock which could be acquired upon
exercise in full of all such rights or warrants and the denominator of which
shall be the number of shares of Common Stock outstanding immediately before
such issuance of rights or warrants plus the number of shares of Common Stock
which could be purchased, at the Fair Market Value of the Common Stock at the
time of such issuance, by the maximum aggregate consideration payable upon
exercise in full of all such rights or warrants.

                  (C) In the event that holders of shares of Common Stock
receive after the Effective Date in respect of their shares of Common Stock any

                                       7
<PAGE>

right or warrant to purchase capital stock of the Corporation (other than shares
of Common Stock), including as such a right, for all purposes of this paragraph,
any security convertible into or exchangeable for capital stock of the
Corporation (other than Common Stock), at a purchase price per share less than
the Fair Market Value of such shares of capital stock on the date of issuance of
such right or warrant, then and in each such event the dividend rights, voting
rights and rights upon liquidation, dissolution or winding up of the Corporation
of the shares of Series A Preferred Stock shall each be adjusted so that after
such event each holder of a share of Series A Preferred Stock shall be entitled,
in respect of each share of Series A Preferred Stock held, in addition to such
rights in respect thereof to which such holder was entitled immediately prior to
such event, to receive (i) such additional dividends as equal the Dividend
Multiple in effect immediately prior to such event multiplied, first, by the
additional dividends to which the holder of a share of Common Stock shall be
entitled upon exercise of such right or warrant by virtue of the capital stock
which could be acquired upon such exercise and multiplied again by the Discount
Fraction (as hereinafter defined) and (ii) such additional voting rights as
equal the Vote Multiple in effect immediately prior to such event multiplied,
first, by the additional voting rights to which the holder of a share of Common
Stock shall be entitled upon exercise of such right or warrant by virtue of the
capital stock which could be acquired upon such exercise and multiplied again by
the Discount Fraction and (iii) such additional distributions upon liquidation,
dissolution or winding up of the Corporation as equal the Liquidation Multiple
in effect immediately prior to such event multiplied, first, by the additional
amount which the holder of a share of Common Stock shall be entitled to receive
upon liquidation, dissolution or winding up of the Corporation upon exercise of
such right or warrant by virtue of the capital stock which could be acquired
upon such exercise and multiplied again by the Discount Fraction. For purposes
of this paragraph, the "Discount Fraction" shall be a fraction the numerator of
which shall be the difference between the Fair Market Value of a share of the
capital stock subject to a right or warrant distributed to holders of shares of
Common Stock as contemplated by this paragraph immediately after the
distribution thereof and the purchase price per share for such share of capital
stock pursuant to such right or warrant and the denominator of which shall be
the Fair Market Value of a share of such capital stock immediately after the
distribution of such right or warrant.

                  (D) For purposes of this Certificate of Designations, the
"Fair Market Value" of a share of capital stock of the Corporation (including a
share of Common Stock) on any date shall be deemed to be the average of the
daily closing prices per share thereof of such stock over the 30 consecutive
Trading Days (as such term is hereinafter defined) immediately prior to such
date; provided, however, that, in the event that the Fair Market Value of any
such share of capital stock is to be determined as of a date that is within 30
Trading Days after (i) the ex-dividend date for a dividend or distribution on
stock payable in shares of such stock or securities convertible into shares of
such stock, or (ii) the effective date of any subdivision, split, combination,
consolidation, reverse stock split or reclassification of such stock, then, and
in each such case, the Fair Market Value shall be appropriately adjusted by the
Board of Directors of the Corporation to take into account such dividend,
distribution, subdivision, split, combination, consolidation, reverse stock
split or reclassification. The closing price for any day shall be the last sale
price, regular way, or, in case, no such sale takes place on such day, the

                                       8
<PAGE>

average of the closing bid and asked prices, regular way (in either case, as
reported in the applicable transaction reporting system with respect to
securities listed or admitted to trading on the Nasdaq National Market); or, if
the shares are not listed or admitted to trading on the Nasdaq National Market,
as reported in the applicable transaction reporting system with respect to
securities listed on the principal national securities exchange or Nasdaq market
on which the shares are listed or admitted to trading; or, if the shares are not
listed or admitted to trading on any national securities exchange or Nasdaq
market, the last quoted price (or, if not so quoted, the average of the high bid
and low asked prices) in the over-the-counter market, as reported by the
National Association of Securities Dealers, Inc. Automated Quotation System
("NASDAQ") or such other quotation reporting system then in use; or if no bids
for such shares are so quoted, the average of the closing bid and asked prices
as furnished by a professional market maker making a market in the shares
selected by the Board of Directors of the Corporation. The term "Trading Day"
shall mean a day on which the principal national securities exchange or Nasdaq
market on which the shares are listed or admitted to trading is open for the
transaction of business or, if the shares are not listed or admitted to trading
on any national securities exchange or Nasdaq market, on which the Nasdaq
National Market or such other national securities exchange as may be selected by
the Board of Directors of the Corporation is open. If the shares are not
publicly held or not so listed or traded on any day within the period of 30
Trading Days applicable to the determination of Fair Market Value thereof as
aforesaid, "Fair Market Value" shall mean the fair market value thereof per
share as determined in good faith by the Board of Directors of the Corporation.
In either case referred to in the foregoing sentence, the determination of Fair
Market Value shall be described in a statement filed with the Secretary of the
Corporation.

                  Section 8. Consolidation, Merger, etc. In case the Corporation
shall enter into any consolidation, merger, combination or other transaction in
which the shares of Common Stock are exchanged for or changed into other stock
or securities, cash and/or any other property, then in any such case each
outstanding share of Series A Preferred Stock shall at the same time be
similarly exchanged for or changed into the aggregate amount of stock,
securities, cash and/or other property (payable in like kind), as the case may
be, for which or into which each share of Common Stock is changed or exchanged
multiplied by the highest of the Vote Multiple, the Dividend Multiple or the
Liquidation Multiple in effect immediately prior to such event.

                  Section 9. Effective Time of Adjustments.

                  (A) Adjustments to the Series A Preferred Stock required by
the provisions hereof shall be effective as of the time at which the event
requiring such adjustments occurs.

                  (B) The Corporation shall give prompt written notice to each
holder of a share of Series A Preferred Stock of the effect of any adjustment to
the voting rights, dividend rights or rights upon liquidation, dissolution or
winding up of the Corporation of such shares required by the provisions of this
Certificate of Designations. Notwithstanding the foregoing sentence, the failure

                                       9
<PAGE>

of the Corporation to give such notice shall not affect the validity of or the
force or effect of or the requirement for such adjustment.

                  Section 10. No Redemption. The shares of Series A Preferred
Stock shall not be redeemable at the option of the Corporation or any holder
thereof. Notwithstanding the foregoing sentence of this Section, the Corporation
may acquire shares of Series A Preferred Stock in any other manner permitted by
law and the provisions hereof and the Restated Certificate of Incorporation of
the Corporation.

                  Section 11. Ranking. Unless otherwise provided in the Restated
Certificate of Incorporation of the Corporation, or a certificate of
designations relating to a subsequent series of preferred stock of the
Corporation, the Series A Preferred Stock shall rank junior to all other series
of the Corporation's preferred stock as to the payment of dividends and the
distribution of assets on liquidation, dissolution or winding up and senior to
the Common Stock.

                  Section 12. Amendment. The provisions hereof and the Restated
Certificate of Incorporation of the Corporation shall not be amended in any
manner which would adversely affect the rights, privileges or powers of the
Series A Preferred Stock without, in addition to any other vote of stockholders
required by law, the affirmative vote of the holders of two-thirds or more of
the outstanding shares of Series A Preferred Stock, voting together as a single
class.

                  Section 13. Fractional Shares. Shares representing Series A
Preferred Stock may be issued in fractions of a share which shall entitle the
holder, in proportion to such holder's fractional shares, to exercise voting
rights, receive dividends, participate in distributions and have the benefit of
all other rights of holders of shares of Series A Preferred Stock. Any reference
in this Certificate of Designations to shares of Series A Preferred Stock shall
be deemed also to refer to fractions of shares of Series A Preferred Stock.

                  IN WITNESS WHEREOF, I have executed and subscribed this
