Item 1.       Description of Registrant's Securities to be Registered.
              -------------------------------------------------------

       On May 28, 1997, the Board of Directors of Source Services Corporation
(the "Company") declared a dividend of one Right for each outstanding common
share (a "Right"), par value $.02 per share (the "Common Shares"), of the
Company.  The dividend is payable on June 18, 1997 (the "Record Date") to the
stockholders of record on that date.  Each Right entitles the registered holder
to purchase from the Company one one-hundredth of a share of Series A Junior
Participating Preferred Stock, par value $.01 per share (the "Preferred
Shares"), of the Company at a price of $90 per one one-hundredth of a Preferred
Share (the "Purchase Price"), subject to adjustment.  The Purchase Price was
established by the Board of Directors after consultations with and
recommendations by its financial advisor.  Customary factors considered by the
Board in determining the Purchase Price included, without limitation, implied
ranges of future stock prices for the Company based upon potential and
projected growth rates over a ten-year period, and exercise prices (as a
multiple of stock prices) set by other companies adopting similar rights plans.
The Purchase Price does not reflect the Board's view of the current value of
the Company.

       The description and terms of the Rights are set forth in a Rights
Agreement (the "Rights Agreement") between the Company and ChaseMellon
Shareholder Services L.L.C., as Rights Agent (the "Rights Agent").

       Until the earlier of (i) the close of business on the tenth day after
the first public announcement that a person or group of affiliated or
associated persons have acquired beneficial ownership of 20% or more of the
outstanding Common Shares (an "Acquiring Person"), or (ii) the close of
business on the tenth day (or such later date as may be determined by action of
the Board of Directors prior to such time as any Person becomes an Acquiring
Person) following the commencement of, or announcement of an intention to make,
a tender offer or exchange offer the consummation of which would result in the
beneficial ownership by such person or group of 20% or more of such outstanding
Common Shares (the earlier of such dates being called the "Distribution Date"),
the Rights will be evidenced by the Common Share certificates, will be
transferable only by the transfer of the Common Shares associated with such
Rights and any transfer of the Common Shares (including a transfer to the
Company) will constitute a transfer of the Rights.  As described below, after a
person or group becomes an Acquiring Person, the Rights may not be redeemed or
amended.

       Until the Distribution Date (or earlier redemption or expiration of the
Rights), new Common Share certificates issued after the Record Date, upon
transfer or new issuance of Common Shares, will contain a legend incorporating
the Rights Agreement by reference.  Until the Distribution Date (or earlier
redemption or expiration of the Rights), the surrender for transfer of any
certificates for Common Shares outstanding as of the Record Date, even without
such notation will also constitute the transfer of the Rights associated with
the Common Shares represented by such certificate.  As soon as practicable
following the Distribution Date, separate certificates evidencing the Rights
("Rights Certificates") will be mailed to holders of record of the Common
Shares as of the close of business on the Distribution Date and such separate
Rights Certificates alone will evidence the Rights.


                                     -2-

<PAGE>   3
       The Rights are not exercisable until the Distribution Date.  The Rights
will expire on June 18, 2007 (the "Final Expiration Date"), unless the Final
Expiration Date is extended or unless the Rights are redeemed earlier by the
Company, in each case, as described below.

       If a person or group of affiliated or associated persons becomes an
"Acquiring Person" by obtaining beneficial ownership of more than 20% of the
then outstanding Common Shares, each holder of a Right (other than those
described in the next sentence) will thereafter have the right to receive, upon
exercise, Common Shares (or, in certain circumstances, cash, property or other
securities of the Company) having a value equal to two times the Purchase Price
of the Right.  All Rights that are, or (under certain circumstances specified
in the Rights Agreement) were, beneficially owned by any Acquiring Person will
be void.

       At any time after the first date of public announcement by the Company
or an Acquiring Person than an Acquiring Person has become such (a "Shares
Acquisition Date"), if (i) the Company is the surviving corporation in a merger
with any other company or entity, (ii) the Company is acquired in a merger or
other business combination transaction, (iii) 50% or more of the Company's
consolidated assets or earning power are sold or (iv) an Acquiring Person
engages in certain "self-dealing" transactions with the Company, each holder of
an outstanding Right (other than those whose Rights have become void) will
thereafter have the right to receive, upon the exercise thereof at the then
current Purchase Price of the Right, that number of shares of common stock of
the surviving or acquiring company or the Acquiring Person, as the case may be,
which at the time of such transaction will have a market value of two times the
exercise price of such Right.

       At any time after a person or group becomes an Acquiring Person and
prior to the acquisition by such person or group of 50% or more of the
outstanding Common Shares, the Board of Directors of the Company may exchange
the Rights (other than Rights owned by an Acquiring Person which have become
void), in whole or in part, without any additional payment, for Common Shares
at an exchange ratio of one Common Share (or of a share of a class or series of
the Company's preferred shares having equivalent rights, preferences and
privileges), per Right (subject to adjustment).

       Rights surrendered for exercise must be accompanied by payment to the
Company of the then current exercise price by wire transfer, certified check,
cashier's check or money order.  Some holders of Rights may find that the level
of the exercise price precludes them from exercising all or a portion of their
Rights.  However, the Rights will be separately tradeable from and after the
Distribution Date, should such holders wish to transfer their Rights.  There
can be no assurance that an active trading market for the Rights will develop.

       The Purchase Price payable, and the number of Preferred Shares or other
securities or property issuable, upon exercise of the Rights are subject to
adjustment from time to time to prevent dilution (i) in the event of a stock
dividend on, or a subdivision, combination or reclassification of, the
Preferred Shares, (ii) upon the grant to holders of the Preferred Shares of
certain rights or warrants to subscribe for or purchase Preferred Shares at a
price, or securities convertible into Preferred Shares with a conversion price,
less than the then-current market price of the Preferred Shares or (iii) upon
the distribution to holders of the Preferred Shares of evidences of
indebtedness or assets (excluding regular periodic cash dividends or


                                     -3-
<PAGE>   4
dividends payable in Preferred Shares) or of subscription rights or warrants
(other than those referred to above).

       Preferred Shares purchasable upon exercise of the Rights will not be
redeemable.  Each Preferred Share will be entitled to an aggregate dividend of
100 times the dividend declared per Common Share.  In the event of liquidation,
the holders of the Preferred Shares will be entitled to an aggregate payment of
100 times the payment made per Common Share.  Each Preferred Share will have
100 votes, voting together with the Common Shares.  In the event of any
consolidation, merger, combination or other transaction in which Common Shares
are exchanged for or changed into other stock or securities, cash and/or other
property, each Preferred Share will be entitled to receive 100 times the amount
received per Common Share.  The foregoing dividend and liquidation rights of
the Preferred Shares are protected against dilution in the event additional
Common Shares are issued pursuant to a stock split, stock dividend or similar
recapitalization.

       Because of the nature of the dividend, liquidation and voting rights of
the Preferred Shares, the value of one one-hundredth of a Preferred Share
purchasable upon exercise of each Right should approximate the value of one
Common Share.

       With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments require an adjustment of at least 1% in
such Purchase Price.  No fractional Preferred Shares will be issued (other than
fractions which are integral multiples of one one-hundredth of a Preferred
Share, which may, at the election of the Company, be evidenced by depositary
receipts) and in lieu thereof, an adjustment in cash will be made based on the
market price of the Preferred Shares on the last trading day prior to the date
of exercise.

       At any time prior to the Shares Acquisition Date, the Board of Directors
of the Company may redeem all, but not less than all, of the Rights at a price
of $.01 per Right (the "Redemption Price").  The redemption of the Rights may
be made effective at such time, on such basis and with such conditions as the
Board of Directors in its sole discretion may establish.  Immediately upon any
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.

       Any of the provisions of the Rights may be amended by the Board of
Directors of the Company prior to the Shares Acquisition Date.  After the
Shares Acquisition Date, the provisions of the Rights Agreement may be amended
by the Board in order to cure any ambiguity or to make changes which do not
adversely affect the interests of holders of Rights (excluding the interests of
any Acquiring Person).

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

       The Rights have certain anti-takeover effects.  The Rights should not
interfere with any merger or business combination approved by the Board of
Directors since the Rights may be redeemed by the Company at the Redemption
Price prior to the time that a person or group has acquired beneficial
ownership of 20% or more of the Common Shares.  However, by causing


                                     -4-

<PAGE>   5
substantial dilution to a person or group that attempts to acquire the Company
on terms not approved by the Company's Board of Directors, the Rights may
interfere with certain acquisitions, including acquisitions that may offer a
premium over market price to some or all of the Company's stockholders.  The
Board of Directors has stated that the Rights are not intended to prevent an
acquisition of the Company on terms that are favorable and fair to all
stockholders.

       As of June 3, 1997, there were 9,134,828 Common Shares outstanding.
Each outstanding Common Share on June 18, 1997 will have one Right attached
thereto.  Until the Distribution Date, the Company will issue one Right with
each Common Share that shall become outstanding so that all such shares will
have attached Rights.  200,000 Preferred Shares are initially reserved for
issuance upon exercise of the Rights.

                                RIGHTS AGREEMENT


         Agreement, dated as of May 30, 1997, between Source Services
Corporation, a Delaware corporation (the "Company"), and ChaseMellon
Shareholder Services L.L.C. (the "Rights Agent").

         The Board of Directors of the Company has authorized and declared a
dividend of one preferred share purchase right (a "Right") for each Common
Share (as hereinafter defined) of the Company outstanding on June 18, 1997 (the
"Record Date"), each Right representing the right to purchase one one-hundredth
of a Preferred Share (as hereinafter defined), upon the terms and subject to
the conditions herein set forth, and has further authorized and directed the
issuance of one Right with respect to each Common Share that shall become
outstanding between the Record Date and the earliest of the Distribution Date,
the Redemption Date and the Final Expiration Date (as such terms are
hereinafter defined).

         Accordingly, in consideration of the premises and the mutual
agreements herein set forth, the parties hereby agree as follows:

         Section 1.       Certain Definitions.  For purposes of this Agreement,
the following terms have the meanings indicated:

                 (a)      "Acquiring Person" shall mean any Person (as such
         term is hereinafter defined) who or which, together with all
         Affiliates and Associates (as such terms are hereinafter defined) of
         such Person, shall be the Beneficial Owner (as such term is
         hereinafter defined) of 20% or more of the Common Shares of the
         Company then outstanding, but shall not include (i) the Company, (ii)
         any Subsidiary (as such term is hereinafter defined) of the Company,
         (iii) any employee benefit plan of the Company or any Subsidiary of
         the Company, or (iv) any entity organized, appointed or established by
         the Company for or pursuant to the terms of any such plan.
         Notwithstanding the foregoing, no Person shall become an "Acquiring
         Person" as the result of (a) an acquisition of Common Shares by the
         Company which, by reducing the number of shares outstanding, increases
         the proportionate number of shares beneficially owned by such Person
         to 20% or more of the Common Shares of the Company then outstanding or
         (b) the acquisition by such Person of newly issued Common Shares
         directly from the Company (it being understood that a purchase from an
         underwriter or other intermediary is not directly from the Company);
         provided, however, that if a Person shall become the Beneficial Owner
         of 20% or more of the Common Shares of the Company then outstanding by
         reason of share purchases by the Company or the receipt of
         newly-issued Common Shares directly from the Company and shall, after
         such share purchases or direct issuance by the Company, become the
         Beneficial Owner of any additional Common Shares of the Company, then
         such Person shall be deemed to be an "Acquiring Person".
         Notwithstanding the foregoing, if the Board of Directors of the
         Company determines in good faith that a Person who would otherwise be
         an "Acquiring Person", as defined pursuant to the foregoing provisions
         of this Section 1(a), has become such inadvertently, and such Person
         divests as promptly as practicable a sufficient number of
<PAGE>   5





         Common Shares so that such Person would no longer be an Acquiring
         Person, as defined pursuant to the foregoing provisions of this
         Section 1(a), then such Person shall not be deemed to be an "Acquiring
         Person" for any purposes of this Agreement.

                 (b)      "Affiliate" and "Associate" shall have the respective
         meanings ascribed to such terms in Rule 12b-2 of the General Rules and
         Regulations under the Exchange Act as in effect on the date of this
         Agreement.

                 (c)      A Person shall be deemed the "Beneficial Owner" of
         and shall be deemed to "beneficially own" any securities:

                           (i)    which such Person or any of such Person's
                 Affiliates or Associates beneficially owns, directly or
                 indirectly;

                          (ii)    which such Person or any of such Person's
                 Affiliates or Associates, directly or indirectly, has (A) the
                 right to acquire (whether such right is exercisable
                 immediately or only after the passage of time) pursuant to any
                 agreement, arrangement or understanding (other than customary
                 agreements with and between underwriters and selling group
                 members with respect to a bona fide public offering of
                 securities), or upon the exercise of conversion rights,
                 exchange rights, rights, warrants or options, or otherwise;
                 provided, however, that a Person shall not be deemed the
                 Beneficial Owner of, or to beneficially own, (x) securities
                 tendered pursuant to a tender or exchange offer made by or on
                 behalf of such Person or any of such Person's Affiliates or
                 Associates until such tendered securities are accepted for
                 purchase or exchange, (y) securities issuable upon exercise of
                 Rights at any time prior to the occurrence of a Triggering
                 Event or (z) securities issuable upon exercise of Rights from
                 and after the occurrence of a Triggering Event which Rights
                 were acquired by such Person or any of such Person's
                 Affiliates or Associates prior to the Distribution Date or
                 pursuant to Section 3(a) or Section 22 hereof (the "Original
                 Rights") or pursuant to Section 11(i) hereof in connection
                 with an adjustment made with respect to any Original Rights;
                 or (B) the sole or shared right to vote or dispose pursuant to
                 any agreement, arrangement or understanding; provided,
                 however, that a Person shall not be deemed the Beneficial
                 Owner of, or to beneficially own, any security if the
                 agreement, arrangement or understanding to vote such security
                 (1) arises solely from a revocable proxy or consent given to
                 such Person in response to a public proxy or consent
                 solicitation made pursuant to, and in accordance with, the
                 applicable rules and regulations promulgated under the
                 Exchange Act and (2) is not also then reportable on Schedule
                 13D or Schedule 13G under the Exchange Act (or any comparable
                 or successor report); or (C) has "beneficial ownership" of (as
                 determined pursuant to Rule 13d-3 of the General Rules and
                 Regulations under the Exchange Act); or

                 indirectly, by any other Person (or any Affiliate or Associate
                 thereof) with which such Person or any of such Person's
                 Affiliates or Associates has any agreement, arrangement or
                 understanding, whether written or oral (other than customary
                 agreements with and between underwriters and selling group
                 members with respect to a bona fide public offering of
                 securities), for the purpose of acquiring, holding, voting
                 (except to the extent contemplated by the proviso to Section
                 1(c)(ii)(B)) or disposing of any securities of the Company.

                 Notwithstanding anything in this definition of Beneficial
         Ownership to the contrary, the phrase "then outstanding," when used
         with reference to a Person's Beneficial Ownership of securities of the
         Company, shall mean the number of such securities then issued and
         outstanding together with the number of such securities not then
         actually issued and outstanding which such Person would be deemed to
         own beneficially hereunder.

         P.M., Dallas, Texas time, on such date; provided, however, that if
         such date is not a Business Day it shall mean 5:00 P.M., Dallas, Texas
         time, on the next succeeding Business Day.

                 (f)     "Common Shares" when used with reference to the
         Company shall mean the shares of Common Stock, par value $.02 per
         share, of the Company.  "Common Shares" when used with reference to

         equity interest) of such other Person with the greatest voting power,
         or the equity securities or other equity interest having power to
         control or direct the management of such Person.

         commencement by any Person (other than the Company, any Subsidiary of
         the Company, any employee benefit plan of the Company or of any
         Subsidiary of the Company or any person or entity organized, appointed

         employee benefit plan of the Company or of any Subsidiary of the
         Company or any person or entity organized, appointed or established by
         the Company for or pursuant to the terms of any such plan) to
         commence, a tender or exchange offer the consummation of which would
         result in any Person becoming the Beneficial Owner of Common Shares
         aggregating 20% or more of the then outstanding Common Shares
         (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 will be

         certificates for Common Shares registered





                                       4
<PAGE>   8





         in the names of the holders thereof (which certificates shall also be
         deemed to be certificates for Rights) and not by separate
         certificates, (y) the Rights will be transferable only in connection
         with the transfer of Common Shares and (z) each transfer of Common
         Shares (including a transfer to the Company) shall constitute a
         transfer of the Rights associated with such Common Shares.  As soon as
         practicable after the Distribution Date, the Company will prepare and
         execute, the Rights Agent will countersign, and the Company will send
         or cause to be sent (and the Rights Agent will, if requested, send) by
         first-class, insured, postage-prepaid mail, to each record holder of
         Common Shares as of the Close of Business on the Distribution Date, at
         the address of such holder shown on the records of the Company, a
         Rights Certificate, in substantially the form of Exhibit B hereto (a
         "Rights Certificate"), evidencing one Right for each Common Share so
         held.  As of the Distribution Date, the Rights will be evidenced
         solely by such Rights Certificates.

                 (b)     On the Record Date, or as soon as practicable
         thereafter, the Company will send a copy of a Summary of Rights to
         Purchase Preferred Shares, in substantially the form of Exhibit C
         hereto (the "Summary of Rights"), by first-class, postage-prepaid
         mail, to each record holder of Common Shares as of the close of
         business on the Record Date, at the address of such holder shown on
         the records of the Company.  With respect to certificates for Common
         Shares outstanding as of the Record Date, until the Distribution Date,
         the Rights will be evidenced by such certificates registered in the
         names of the holders thereof together with a copy of the Summary of
         Rights attached thereto.  Until the Distribution Date (or the earlier
         of the Redemption Date or the Final Expiration Date), the surrender
         for transfer of any certificate for Common Shares outstanding on the
         Record Date, with or without a copy of the Summary of Rights attached
         thereto, shall also constitute the transfer of the Rights associated
         with the Common Shares represented thereby.

                 (c)     Certificates for Common Shares which become
         outstanding (including, without limitation, reacquired Common Shares
         referred to in the last sentence of this Section 3 (c)) after the
         Record Date but prior to the earliest of the Distribution Date, the
         Redemption Date or the Final Expiration Date shall have impressed on,
         printed on, written on or otherwise affixed to them the following
         legend:

                 This certificate also evidences and entitles the holder hereof
                 to certain rights as set forth in a Rights Agreement between
                 Source Services Corporation and ChaseMellon Shareholder
                 Services L.L.C. dated as of May 30, 1997 (the "Rights
                 Agreement"), the terms of which are hereby incorporated herein
                 by reference and a copy of which is on file at the principal
                 executive offices of Source Services Corporation.  Under
                 certain circumstances, as set forth in the Rights Agreement,
                 such Rights will be evidenced by separate certificates and
                 will no longer be evidenced by this certificate.  Source
                 Services Corporation will mail to the holder of this





                                       5
<PAGE>   9





                 certificate a copy of the Rights Agreement without charge
                 after receipt of a written request therefor.  As described in
                 the Rights Agreement, Rights issued to any Person who becomes
                 an Acquiring Person or any Associate or Affiliate thereof (all
                 as defined in the Rights Agreement) shall become null and
                 void.

         With respect to such certificates containing the foregoing legend,
         until the Distribution Date, the Rights associated with the Common
         Shares represented by such certificates shall be evidenced by such
         certificates alone, and the surrender for transfer of any such
         certificate shall also constitute the transfer of the Rights
         associated with the Common Shares represented thereby.  In the event
         that the Company purchases or acquires any Common Shares after the
         Record Date but prior to the Distribution Date, any Rights associated
         with such Common Shares shall be deemed cancelled and retired so that
         the Company shall not be entitled to exercise any Rights associated
         with the Common Shares which are no longer outstanding.

         Section 4.      Form of Rights Certificates.

                 (a)     The Rights Certificates and the forms of election to
         purchase and of assignment to be printed on the reverse thereof, shall
         be substantially the same as Exhibit B hereto, and may have such marks
         of identification or designation and such legends, summaries or
         endorsements printed thereon as the Company may deem appropriate and
         as are not inconsistent with the provisions of this Agreement, or as
         may be required to comply with any applicable law or with any rule or
         regulation made pursuant thereto or with any rule or regulation of any
         stock exchange on which the Rights may from time to time be listed, or
         to conform to usage.  Subject to the terms, provisions and
         restrictions elsewhere herein, the Rights Certificates shall entitle
         the holders thereof to purchase such number of one one-hundredths of a
         Preferred Share as shall be set forth therein at the price per one
         one-hundredth of a Preferred Share set forth therein (the "Purchase
         Price"), but the amount and type of securities purchasable upon the
         exercise of each Right and the Purchase Price shall be subject to
         adjustment as provided herein.

                 (b)     Any Rights Certificate issued pursuant to Section 3(a)
         or Section 22 hereof that represents Rights beneficially owned by:
         (i) an Acquiring Person or any Associate or Affiliate of an Acquiring
         Person, (ii) a transferee of an Acquiring Person (or of any such
         Associate or Affiliate) who becomes a transferee after the Acquiring
         Person becomes such, or (iii) a transferee of an Acquiring Person (or
         of any such Associate or Affiliate) who becomes a transferee prior to
         or concurrently with the Acquiring Person becoming such and receives
         such Rights pursuant to either (A) a transfer (whether or not for
         consideration) from the Acquiring Person to holders of equity
         interests in such Acquiring Person or to any Person with whom such
         Acquiring Person has any continuing agreement, arrangement or
         understanding, whether written or oral, regarding the transferred
         Rights or (B) a transfer which the Board of Directors of the Company
         has





                                       6
<PAGE>   10





         determined in good faith is part of a plan, arrangement or
         understanding, whether written or oral, which has as a primary purpose
         or effect avoidance of the second paragraph of Section 11(a)(ii)
         hereof, and any Rights Certificate issued pursuant to Section 6 or
         Section 11 hereof upon transfer, exchange, replacement or adjustment
         of any other Rights Certificate referred to in this sentence, shall
         contain (to the extent feasible) the following legend:

                 The Rights represented by this Rights Certificate are or were
                 beneficially owned by a Person who was or became an Acquiring
                 Person or an Affiliate or Associate of an Acquiring Person (as
                 such terms are defined in the Rights Agreement).  Accordingly,
                 this Rights Certificate and the Rights represented hereby may
                 become null and void in the circumstances specified in Section
                 11(a)(ii) of such Agreement.

         The provisions of the second paragraph of Section 11(a)(ii) shall
apply whether or not any Rights Certificate actually contains the foregoing
legend.

         Section 5.      Countersignature and Registration.  The Rights
Certificates shall be executed on behalf of the Company by its Chairman of the
Board, its Chief Executive Officer, its President, any of its Vice Presidents,
or its Treasurer, either manually or by facsimile signature, shall have affixed
thereto the Company's seal or a facsimile thereof, and shall be attested by the
Secretary or an Assistant Secretary of the Company, either manually or by
facsimile signature.  The Rights Certificates shall be manually countersigned
by the Rights Agent and shall not be valid for any purpose unless
countersigned.  In case any officer of the Company who shall have signed any of
the Rights Certificates shall cease to be such officer of the Company before
countersignature by the Rights Agent and issuance and delivery by the Company,
such Rights Certificates, nevertheless, may be countersigned by the Rights
Agent and issued and delivered by the Company with the same force and effect as
though the Person who signed such Rights Certificates had not ceased to be such
officer of the Company; and any Rights Certificate may be signed on behalf of
the Company by any Person who, at the actual date of the execution of such
Rights Certificate, shall be a proper officer of the Company to sign such
Rights Certificate, although at the date of the execution of this Rights
Agreement any such Person was not such an officer.

         Following the Distribution Date, the Rights Agent will keep or cause
to be kept, at its principal office, books for registration and transfer of the
Rights Certificates of each series issued hereunder.  Such books shall show the
names and addresses of the respective holders of the Rights Certificates, the
number of Rights evidenced on its face by each of the Rights Certificates and
the date of each of the Rights Certificates.

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

                 (a)     Subject to the provisions of Sections 4(b), 14 and 24
         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
         Redemption Date or the Final Expiration Date, any Rights Certificate
         or Rights Certificates (other than Rights Certificates representing
         Rights that have become void pursuant to Section 11(a)(ii) hereof or
         that have been exchanged pursuant to Section 24 hereof) may be
         transferred, split-up, combined or exchanged for another Rights
         Certificate or Rights Certificates, entitling the registered holder to
         purchase a like number of one one-hundredths of a Preferred Share (or
         Common Shares, other securities or property, as the case may be) as
         the Rights Certificate or Rights Certificates surrendered then entitle
         such holder to purchase.  Any registered holder desiring to transfer,
         split-up, combine or exchange any Rights Certificate or Rights
         Certificates shall make such request in writing delivered to the
         Rights Agent, and shall surrender the Rights Certificate or Rights
         Certificates to be transferred, split-up, combined or exchanged at the
         principal office of the Rights Agent.  Neither the Rights Agent nor
         the Company shall be obligated to take any action whatsoever with
         respect to the transfer of any such surrendered Rights Certificate
         until the registered holder shall have completed and signed the
         certificate contained in the form of assignment on the reverse side of
         such Rights Certificate and shall have provided such additional
         evidence of the identity of the Beneficial Owner (or former Beneficial
         Owner) or Affiliates or Associates thereof as the Company shall
         reasonably request.  Thereupon the Rights Agent shall, subject to
         Sections 4 and 11(a)(ii) hereof, countersign and deliver to the Person
         entitled thereto a Rights Certificate or Rights Certificates, as the
         case may be, as so requested.  The Company may require payment of a
         sum sufficient to cover any tax or governmental charge that may be
         imposed in connection with any transfer, split-up, combination or
         exchange of Rights Certificates.

                 (b)     Upon receipt by the Company and the Rights Agent of
         evidence reasonably satisfactory to them of the loss, theft,
         destruction or mutilation of a Rights Certificate, and, in case of
         loss, theft or destruction, of indemnity or security reasonably
         satisfactory to them, and, at the Company's request, reimbursement to
         the Company and the Rights Agent of all reasonable expenses incidental
         thereto, and upon surrender to the Rights Agent and cancellation of
         the Rights Certificate, if mutilated, the Company will make and
         deliver a new Rights Certificate of like tenor to the Rights Agent for
         delivery to the registered holder in lieu of the Rights Certificate so
         lost, stolen, destroyed or mutilated.

         Section 7.      Exercise of Rights; Purchase Price; Expiration Date of
Rights.

                 (a)     Subject to Section 11(a)(ii) hereof, the registered
         holder of any valid Rights Certificate may exercise the Rights
         evidenced thereby (except as otherwise provided herein including,
         without limitation, the restrictions on exercisability set forth in
         Section 9(c) hereof) in whole or in part at any time after the
         Distribution Date upon surrender





                                       8

         of the Rights Certificate, with the form of election to purchase on
         the reverse side thereof duly executed, to the Rights Agent at the
         principal office of the Rights Agent, together with payment of the
         Purchase Price (as defined below) for each one one-hundredth of a
         Preferred Share (or Common Shares, other securities, cash or other
         assets, as the case may be) as to which the Rights are exercised, at
         or prior to the earliest of (i) the close of business on June 18, 2007
         (the "Final Expiration Date"), (ii) the time at which the Rights are
         redeemed as provided in Section 23 hereof (the "Redemption Date"), or
         (iii) the time at which such Rights are exchanged as provided in
         Section 24 hereof.

                 (b)     The Purchase Price for each one one-hundredth of a
         Preferred Share to be issued upon exercise of a Right shall initially
         be $90, shall be subject to adjustment from time to time as provided
         in Sections 11 and 13 hereof and shall be payable in lawful money of
         the United States of America in accordance with paragraph (c) below.

                 (c)     Upon receipt of a Rights Certificate representing
         exercisable Rights, with the form of election to purchase and the
         certificate on the reverse side of the Rights Certificate duly
         executed, accompanied by payment of the Purchase Price for the shares
         (or other securities or property, as the case may be) to be purchased
         and an amount equal to any applicable transfer tax required to be paid
         by the holder of such Rights Certificate in accordance with Section 9
         hereof by wire transfer, certified check, cashier's check or money
         order payable to the order of the Company, or such other payment
         method reasonably required by the Company, the Rights Agent shall
         thereupon promptly (i) (A) requisition from any transfer agent of the
         Preferred Shares (or make available if the Rights Agent is the
         transfer agent of the Preferred Shares) certificates for the number of
         Preferred Shares to be purchased and the Company hereby irrevocably
         authorizes its transfer agent to comply with all such requests or (B)
         requisition from the depositary agent depositary receipts as provided
         in Section 14(b) hereof, representing such number of one
         one-hundredths of a Preferred Share as are to be purchased (in which
         case certificates for the Preferred Shares represented by such
         receipts shall be deposited by the transfer agent with the depositary
         agent and the Company hereby directs the depositary agent to comply
         with such request, (ii) when appropriate, requisition from the Company
         or such other entity the amount of cash to be paid in lieu of issuance
         of fractional shares in accordance with Section 14 hereof, (iii) after
         receipt of such certificates or depositary receipts, cause the same to
         be delivered to or upon the order of the registered holder of such
         Rights Certificate, registered in such name or names as may be
         designated by such holder, and (iv) when appropriate, after receipt,
         deliver such cash to or upon the order of the registered holder of
         such Rights Certificate.  In the event that the Company elects or is
         obligated to issue other securities (including Common Shares) of the
         Company, pay cash and/or distribute other property pursuant to Section
         11(a)(iii) hereof, the Company will make all arrangements necessary so
         that such other securities, cash and/or property are available for
         distribution by the Rights Agent, if and when appropriate.

<PAGE>   13





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

                 (e)     Notwithstanding anything in this Agreement to the
         contrary, neither the Rights Agent nor the Company 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 contained in the form of election to purchase set forth on
         the reverse side of the Rights 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 as the Company shall reasonably request.

                 (f)     Notwithstanding any statement to the contrary
         contained in this Agreement or in any Rights Certificate, if the
         Distribution Date or the Shares Acquisition Date shall occur prior to
         the Record Date, the provisions of this Agreement, including (without
         limitation) Sections 3 and 11(a)(ii), shall be applicable to the
         Rights upon their issuance to the same extent such provisions would
         have been applicable if the Record Date were the date of this
         Agreement.

         Section 8.      Cancellation and Destruction of Rights Certificates.
All Rights Certificates surrendered for the purpose of exercise, transfer,
split-up, combination or exchange shall, if surrendered to the Company 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 Rights Certificates shall be issued in lieu thereof except as
expressly permitted by any of the provisions of this Rights Agreement.  The
Company shall deliver to the Rights Agent for cancellation and retirement, and
the Rights Agent shall so cancel and retire, any other Rights Certificate
purchased or acquired by the Company otherwise than upon the exercise thereof.
The Rights Agent shall deliver all cancelled Rights Certificates to the
Company, or shall, at the written request of the Company, destroy such
cancelled Rights Certificates, and in such case shall deliver a certificate of
destruction thereof to the Company.

         Section 9.      Availability of Capital Stock.

                 (a)     The Company covenants and agrees that it will cause to
         be reserved and kept available out of its authorized and unissued
         Preferred Shares (and, following the occurrence of a Distribution
         Date, out of its authorized and unissued Common Shares and/or other
         securities or out of its authorized and issued shares held in its
         treasury), the number of Preferred Shares (or Common Shares and/or
         other securities, as the case may be) that will be sufficient to
         permit the exercise in full of all outstanding Rights as provided in
         this Agreement.





                                       10
<PAGE>   14





                 (b)     The Company covenants and agrees that it will take all
         such action as may be necessary to ensure that all Preferred Shares
         (or Common Shares and/or other securities, as the case may be)
         delivered upon exercise of Rights shall be, at the time of delivery of
         the certificates for such Preferred Shares (or Common Shares and/or
         other securities, as the case may be) (subject to any necessary
         payment of the Purchase Price), duly and validly authorized and issued
         and fully paid and nonassessable shares.

                 (c)     The Company further covenants and agrees that it will
         pay when due and payable any and all federal and state transfer taxes
         and charges which may be payable in respect of the issuance or
         delivery of the Rights Certificates or of any Preferred Shares (or
         Common Shares and/or other securities, as the case may be) upon the
         exercise of Rights.  The Company shall not, however, be required to
         pay any transfer tax which may be payable in respect of any transfer
         or delivery of Rights Certificates to a Person other than, or the
         issuance or delivery of certificates or depositary receipts for the
         Preferred Shares (or Common Shares and/or other securities, as the
         case may be) in a name other than that of, the registered holder of
         the Rights Certificate evidencing Rights surrendered for exercise or
         to issue or to deliver any certificates or depositary receipts for
         Preferred Shares (or Common Shares and/or other securities, as the
         case may be) upon the exercise of any Rights until any such tax shall
         have been paid (any such tax being payable by the holder of such
         Rights Certificate at the time of surrender) or until it has been
         established to the Company's reasonable satisfaction that no such tax
         is due.

                 (d)     So long as the Preferred Shares (and, following the
         occurrence of a Distribution Date, Common Shares and/or other
         securities, as the case may be) issuable and deliverable upon the
         exercise of the Rights may be listed on any inter-dealer quotation
         system or national securities exchange, the Company shall use its best
         efforts to cause, from and after such time as the Rights become
         exercisable, all shares reserved for such issuance to be listed on
         such exchange upon official notice of issuance upon such exercise.

                 (e)     The Company shall use its best efforts to (i) file on
         the appropriate form, as soon as practicable following the earliest
         date after the first occurrence of a Section 11(a)(ii) Event on which
         the consideration to be delivered by the Company upon exercise of the
         Rights has been determined hereunder, a registration statement under
         the Securities Act of 1933, as amended (the "Act"), with respect to
         the securities purchasable upon exercise of the Rights, (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 Act) until the earlier of (A) the date as of which
         the Rights are no longer exercisable for such securities, and (B) the
         Final Expiration Date.  The Company may temporarily suspend, for a
         period of time not to exceed ninety (90) days after the date set forth
         in clause (i) of the first sentence of this Section 9(e), the
         exercisability of the Rights in order to prepare and file such
         registration statement and permit it to become effective.  Upon any
         such suspension, the Company shall issue a public announcement stating
         that the





                                       11
<PAGE>   15





         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.  In addition, if the Company shall determine that a
         registration statement is required following the Distribution Date,
         the Company may temporarily suspend the exercisability of the Rights
         until such time as a registration statement has been declared
         effective.  The Company 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 if the requisite qualification in such jurisdiction shall
         not have been obtained, the exercise thereof shall not be permitted
         under applicable law or a registration statement shall not have been
         declared effective.

         Section 10.     Preferred Shares Record Date.  Each Person in whose
name any certificate for Preferred Shares (or Common Shares and/or other
securities, as the case may be) is issued upon the exercise of Rights shall for
all purposes be deemed to have become the holder of record of the Preferred
Shares (or Common Shares and/or other securities, as the case may be)
represented thereby on, and such certificate shall be dated, the date upon
which the Rights certificate evidencing such Rights was duly surrendered and
payment of the applicable Purchase Price (and any applicable transfer taxes)
was made (or Rights were duly surrendered in exchange for Common Shares
pursuant to Section 24 hereof); provided, however, that if the date of such
surrender and payment is a date upon which the Preferred Shares (or Common
Shares and/or other securities, as the case may be) transfer books of the
Company are closed, such Person shall be deemed to have become the record
holder of such shares on, and such certificate shall be dated, the next
succeeding Business Day on which the Preferred Shares (or Common Shares and/or
other securities, as the case may be) transfer books of the Company are open.
Prior to the exercise of the Rights evidenced thereby, the holder of a Rights
Certificate shall not be entitled to any rights of a holder of Preferred Shares
(or Common Shares and/or other securities, as the case may be) for which the
Rights shall be exercisable, including, without limitation, the right to vote,
to receive dividends or other distributions or to exercise any preemptive
rights, and shall not be entitled to receive any notice of any proceedings of
the Company, except as provided herein.

         Section 11.     Adjustment of Purchase Price, Number and Kind of
Shares or Number of Rights.  The Purchase Price, the number and kind of shares
covered by and obtainable upon exercise of each Right, and the number of Rights
outstanding, are subject to adjustment from time to time as provided in
Sections 11 and 13 of this Agreement.

                          (a)     (i)      In the event the Company shall at
                 any time after the date of this Agreement (A) declare a
                 dividend on the Preferred Shares payable in Preferred Shares,
                 (B) subdivide the outstanding Preferred Shares, (C) combine
                 the outstanding Preferred Shares into a smaller number of
                 Preferred Shares or (D) issue any shares of its capital stock
                 in a reclassification of the Preferred Shares (including any
                 such reclassification in connection with a consolidation or
                 merger in which the Company is the continuing or surviving
                 corporation), except as





                                       12
<PAGE>   16





                 otherwise provided in this Section 11(a), the Purchase Price
                 in effect at the time of the record date for such dividend or
                 of the effective date of such subdivision, combination or
                 reclassification, and the number and kind of shares of capital
                 stock issuable on such date, shall be proportionately adjusted
                 so that the holder of any Right exercised after such time
                 shall be entitled to receive the aggregate number and kind of
                 shares of capital stock which, if such Right had been
                 exercised immediately prior to such date and at a time when
                 the Preferred Shares transfer books of the Company were open,
                 he would have owned upon such exercise and been entitled to
                 receive by virtue of such dividend, subdivision, combination
                 or reclassification; provided, however, that in no event shall
                 the consideration to be paid upon the exercise of one Right be
                 less than the aggregate par value of the shares of capital
                 stock of the Company issuable upon exercise of one Right.  If
                 an event occurs which would require adjustment under both
                 Section 11(a)(i) and Section 11(a)(ii), 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 24 of this
                 Agreement, in the event any Person shall become an Acquiring
                 Person, each holder of a valid Right shall thereafter have a
                 right to receive, upon exercise thereof at a price equal to
                 the then current Purchase Price multiplied by the number of
                 one one-hundredths of a Preferred Share for which a Right is
                 then exercisable, in accordance with the terms of this
                 Agreement, and in lieu of Preferred Shares, such number of
                 Common Shares of the Company as shall equal the result
                 obtained by (x) multiplying the then current Purchase Price by
                 the number of one one-hundredths of a Preferred Share for
                 which, a Right is then exercisable and dividing that product
                 by (y) 50% of the then current per share market price of the
                 Company's Common Shares (determined pursuant to Section 11(d)
                 hereof) on the date of the occurrence of the event described
                 above.  In the event that any Person shall become an Acquiring
                 Person and the Rights shall then be outstanding, the Company
                 shall not take any action which would eliminate or diminish
                 the benefits intended to be afforded by the Rights.

                             From and after the time when a Person becomes an
                 Acquiring Person (a "Section 11(a)(ii) Event") any Rights that

                 Acquiring Person (or any Associate or Affiliate of such
                 Acquiring Person), (ii) a transferee of such Acquiring Person
                 (or of any such Associate or Affiliate) who becomes a
                 transferee after the Acquiring Person became an Acquiring
                 Person or (iii) a transferee of such Acquiring Person (or of
                 any such Associate or Affiliate) who becomes a transferee
                 prior to or concurrently with the Acquiring Person's becoming
                 an Acquiring Person and receives such Rights pursuant to
                 either (A) a transfer (whether or not for consideration) from
                 the Acquiring Person to holders of equity interests in such
                 Acquiring Person or to any Person with whom the Acquiring
                 Person has any

                 continuing agreement, arrangement or understanding, whether
                 written or oral, regarding the transferred Rights or (B) a
                 transfer which the Board of Directors has determined in good
                 faith is part of a plan, arrangement or understanding, whether
                 written or oral, which has as a primary purpose or effect the
                 avoidance of this Section 11(a)(ii), shall each be void and
                 any holder of such Rights shall thereafter have no exercise or
                 any other rights whatsoever with respect to such Rights under
                 any provision of this Agreement or otherwise.  No Rights
                 Certificate shall be issued pursuant to Section 3, this
                 Section 11(a)(ii) or Section 24 that represents Rights
                 beneficially owned by an Acquiring Person or any Associate or
                 Affiliate thereof whose Rights would be void pursuant to the
                 preceding sentence; no Rights Certificate shall be issued at
                 any time upon the transfer of any Rights to an Acquiring
                 Person or any Associate or Affiliate thereof whose Rights
                 would be void pursuant to the preceding sentence or to any
                 nominee of such Acquiring Person, Associate or Affiliate; and
                 any Rights Certificate delivered to the Rights Agent for
                 transfer to an Acquiring Person, Associate or Affiliate
                 thereof whose Rights would be void pursuant to the preceding
                 sentence shall be cancelled.

                                  (iii)    In lieu of issuing Common Shares of
                 the Company in accordance with Section 11(a)(ii) hereof, the
                 Company may, in the sole discretion of the Board of Directors,
                 elect to (and, in the event that the Board of Directors has
                 not exercised the exchange right contained in Section 24
                 hereof and there are not sufficient issued but not outstanding
                 and authorized but unissued Common Shares to permit the
                 exercise in full of the Rights in accordance with the
                 foregoing subparagraph (ii), the Company shall) take all such
                 action as may be necessary to authorize, issue or pay, upon
                 the exercise of the Rights, cash (including by way of a
                 reduction of the Purchase Price), property, other securities
                 or any combination thereof having an aggregate value equal to
                 the value of the Common Shares of the Company which otherwise
                 would have been issuable pursuant to Section 11(a)(ii), which
                 aggregate value shall be determined by the Board of Directors.
                 For purposes of the preceding sentence, the value of the
                 Common Shares shall be determined pursuant to Section 11(d)
                 hereof and the value of any equity securities which the Board
                 of Directors determines to be a "common stock equivalent"
                 (including the Preferred Shares, in such ratio as the Board of
                 Directors shall determine) shall be deemed to have the same
                 value as the Common Shares.  Any such election by the Board of
                 Directors must be made and publicly announced within 60 days
                 following the date on which the event described in Section
                 11(a)(ii) shall have occurred.  Following the occurrence of
                 the event described in Section 11(a)(ii), the Board of
                 Directors may suspend the exercisability of the Rights for a
                 period of up to 60 days following the date on which the event
                 described in Section 11(a)(ii) shall have occurred to the
                 extent that the directors have not determined whether to
                 exercise the Company's right of election under this Section
                 11(a)(iii).  In the event of any such suspension, the Company
                 shall issue a public announcement stating that the
                 exercisability of the Rights has been temporarily suspended.

                 (b)     In case the Company shall fix a record date for the
         issuance of rights, options or warrants to all holders of Preferred
         Shares entitling them (for a period expiring within 45 calendar days
         after such record date) to subscribe for or purchase Preferred Shares
         (or shares having the same rights, privileges and preferences as the
         Preferred Shares ("equivalent preferred shares")) or securities
         convertible into Preferred Shares or equivalent preferred shares at a
         price per Preferred Share or equivalent preferred share (or having a
         conversion price per share, if a security convertible into Preferred
         Shares or equivalent preferred shares) less than the then current per
         share market price of the Preferred Shares (as defined in Section
         11(d)) on such record date, the Purchase Price to be in effect after
         such record date shall be determined by multiplying the Purchase Price
         in effect immediately prior to such record date by a fraction, the
         numerator of which shall be the number of Preferred Shares outstanding
         on such record date plus the number of Preferred Shares which could be
         purchased at the current per share market price for the aggregate
         offering price of the total number of Preferred Shares and/or
         equivalent preferred shares so to be offered (and/or the aggregate
         initial conversion price of the convertible securities so to be
         offered) and the denominator of which shall be the number of Preferred
         Shares outstanding on such record date plus the number of additional
         Preferred Shares and/or equivalent preferred shares to be offered for
         subscription or purchase (or into which the convertible securities so
         to be offered are initially convertible); provided, however, that in
         no event shall the consideration to be paid upon the exercise of one
         Right be less than the aggregate par value of the shares of capital
         stock of the Company issuable upon exercise of one Right.  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 Company, whose determination shall be described in a
         statement filed with the Rights Agent.  Preferred Shares owned by or
         held for the account of the Company 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
         Purchase Price shall be adjusted to be the Purchase Price which would
         then be in effect if such record date had not been fixed.

                 (c)     In case the Company shall fix a record date for the
         making of a distribution to all holders of the Preferred Shares
         (including any such distribution made in connection with a
         consolidation or merger in which the Company is the continuing or
         surviving corporation) of evidences of indebtedness or assets (other
         than a regular quarterly cash dividend or a dividend payable in
         Preferred Shares) or subscription rights or warrants (excluding those
         referred to in Section 11(b) hereof), the Purchase Price to be in
         effect after such record date shall be determined by multiplying the
         Purchase Price in effect immediately prior to such record date by a
         fraction, the numerator of which shall be the then current per share
         market price of the Preferred Shares on such record date, less the
         fair market value (as determined in good faith by the Board of
         Directors of the Company, whose determination shall be described in a
         statement filed with the Rights Agent) of the portion of the assets or
         evidences of indebtedness so to be





                                       15
<PAGE>   19





         distributed or of such subscription rights or warrants applicable to
         one Preferred Share and the denominator of which shall be such current
         per share market price of the Preferred Shares; provided, however,
         that in no event shall the consideration to be paid upon the exercise
         of one Right be less than the aggregate par value of the shares of
         capital stock of the Company to be issued upon exercise of one Right.
         Such adjustments shall be made successively whenever such a record
         date is fixed; and in the event that such distribution is not so made,
         the Purchase Price shall again be adjusted to be the Purchase Price
         which would then be in effect if such record date had not been fixed.

                 (d)     (i)      For the purpose of any computation hereunder,
         the "current per share market price" of any security (a "Security" for
         the purpose of this Section 11(d)(i)) on any date shall be deemed to
         be the average of the daily closing prices (determined as provided in
         the next sentence) per share of such Security for the 30 consecutive
         Trading Days (as such term is hereinafter defined) immediately prior
         to such date, and for the purpose of any computation under Section
         11(a)(iii) hereof, the "current per share market price" of a Security
         on any date shall be deemed to be the average of the daily closing
         prices per share of such Security for the 30 consecutive Trading Days
         immediately following such date; provided, however, that in the event
         that the current per share market price of the Security is determined
         during a period following the announcement by the issuer of such
         Security of (A) a dividend or distribution on such Security payable in
         shares of such Security or securities convertible into such shares
         (other than the Rights), or (B) any subdivision, combination or
         reclassification of such Security and prior to the expiration of 30
         Trading Days after the ex-dividend date for such dividend or
         distribution, or the record date for such subdivision, combination or
         reclassification, then, and in each such case, the current per share
         market price shall be appropriately adjusted to reflect the current
         market price per share equivalent of such Security as if such
         dividend, distribution, combination or reclassification has not been
         declared.  The closing price for each 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 principal consolidated transaction
         reporting system with respect to securities listed on the Nasdaq
         National Market or, if the Security is listed or admitted for trading
         on a national exchange, as reported in the principal consolidated
         transaction reporting system with respect to securities listed on the
         principal national securities exchange on which the Security is listed
         or admitted to trading, or, if the Security is not listed on the
         Nasdaq National Market or listed or admitted to trading on any
         national securities exchange, 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 any other system then in use,
         or, if on any such date the Security is not quoted by any such
         organization, the average of the closing bid and asked prices as
         furnished by a professional market maker making a market in the
         Security selected by the Board of Directors of the Company.  The term
         "Trading Day" shall mean a day on which the principal national
         securities exchange on which the Security is listed or admitted to
         trading is open for the transaction of business or, if the Security is
         not listed or admitted to trading on any national securities exchange,
         a Business Day.

                         (ii)     For the purpose of any computation hereunder,
         the "current per share market price" of the Preferred Shares shall be
         determined in accordance with the method set forth in Section
         11(d)(i).  If the Preferred Shares are not publicly traded, the
         "current per share market price" of the Preferred Shares shall be
         conclusively deemed to be the current per share market price of the
         Common Shares as determined pursuant to Section 11(d)(i)
         (appropriately adjusted to reflect any stock split, stock dividend or
         similar transaction occurring after the date hereof), multiplied by
         one hundred.  If neither the Common Shares nor the Preferred Shares
         are publicly held or so listed or traded, "current per share market
         price" shall mean the fair value per share as determined in good faith
         by the Board of Directors of the Company, whose determination shall be
         described in a statement filed with the Rights Agent.

                 (e)     No adjustment in the Purchase Price shall be required
         unless such adjustment would require an increase or decrease of at
         least 1% in the Purchase Price; provided, however, that any
         adjustments which by reason of this Section 11(e) are not required to
         be made shall be carried forward and taken into account in any
         subsequent adjustment.  All calculations under this Section 11 shall
         be made to the nearest cent or to the nearest one one-millionth of a
         Preferred Share or one ten-thousandth of any other share or security,
         as the case may be.  Notwithstanding the first sentence of this
         Section 11(e), any adjustment required by this Section 11 shall be
         made no later than the earlier of (i) three years from the date of the
         transaction which requires such adjustment or (ii) the date of the
         expiration of the right to exercise any Rights.

                 (f)     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
         Company other than Preferred Shares, thereafter the number of such
         other shares so receivable upon exercise of any 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 Shares contained in Sections 11(a), 11(b) and 11(c), and the
         provisions of Sections 7, 9, 10, 13 and 14 with respect to the
         Preferred Shares shall apply on like terms to any such other shares.

                 (g)     All Rights originally issued by the Company subsequent
         to any adjustment made to the Purchase Price hereunder shall evidence
         the right to purchase, at the adjusted Purchase Price, the number of
         one one-hundredths of a Preferred Share purchasable from time to time
         hereunder upon exercise of the Rights all subject to further
         adjustment as provided herein.

                 (h)     Unless the Company shall have exercised its election
         as provided in Section 11(i), upon each adjustment of the Purchase
         Price as a result of the calculations made in Sections 11(b) and
         11(c), each Right outstanding immediately prior to the making of such
         adjustment shall thereafter evidence the right to purchase, at the
         adjusted Purchase Price, that number of one one-hundredths of a
         Preferred Share (calculated to the nearest one one-millionth of a
         Preferred Share) obtained by (i) multiplying (x) the number of





                                       17
<PAGE>   21





         one one-hundredths of a share covered by a Right immediately prior to
         this adjustment by (y) the Purchase Price in effect immediately prior
         to such adjustment of the Purchase Price and (ii) dividing the product
         so obtained by the Purchase Price in effect immediately after such
         adjustment of the Purchase Price.

                 (i)     The Company may elect on or after the date of any
         adjustment of the Purchase Price to adjust the number of Rights, in
         substitution for any adjustment in the number of one one-hundredths of
         a Preferred Share 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-hundredths of a
         Preferred Share 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 (calculated
         to the nearest one ten-thousandth) obtained by dividing the Purchase
         Price in effect immediately prior to adjustment of the purchase Price
         by the Purchase Price in effect immediately after adjustment of the
         Purchase Price.  The Company 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
         Purchase Price is adjusted or any day thereafter, but, if the Rights
         Certificates have been issued, shall be at least 10 days later than
         the date of the public announcement.  If Rights Certificates have been
         issued, upon each adjustment of the number of Rights pursuant to this
         Section 11(i), the Company shall, as promptly as practicable, cause to
         be distributed to holders of record of Rights Certificates on such
         record date Rights Certificates evidencing, subject to Section 14
         hereof, the additional Rights to which such holders shall be entitled
         as a result of such adjustment, or, at the option of the Company,
         shall cause to be distributed to such holders of record in
         substitution and replacement for the Rights Certificates held by such
         holders prior to the date of adjustment, and upon surrender thereof,
         if required by the Company, new Rights Certificates evidencing all the
         Rights to which such holders shall be entitled after such adjustment.
         Rights 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 Rights
         Certificates on the record date specified in the public announcement.

                 (j)     Irrespective of any adjustment or change in the
         Purchase Price or the number of one one-hundredths of a Preferred
         Share issuable upon the exercise of the Rights, the Rights
         Certificates theretofore and thereafter issued may continue to express
         the Purchase Price and the number of one one-hundredths of a Preferred
         Share which were expressed in the initial Rights Certificates issued
         hereunder, without prejudice to the validity of such Rights
         Certificate(s) or the application of the provisions hereof.

                 (k)     Before taking any action that would cause an
         adjustment reducing the Purchase Price below one one-hundredth of the
         then par value, if any, of the Preferred Shares issuable upon exercise
         of the Rights, the Company shall take any corporate action which may,
         in the opinion of its counsel, be necessary in order that the Company
         may





                                       18
<PAGE>   22





         validly and legally issue fully paid and nonassessable Preferred
         Shares at such adjusted Purchase Price.

                 (l)     In any case in which this Section 11 shall require
         that an adjustment in the Purchase Price be made effective as of a
         record date for a specified event, the Company may elect to defer
         until the occurrence of such event the issuing to the holder of any
         Right exercised after such record date of the Preferred Shares and
         other capital stock or securities of the Company, if any, issuable
         upon such exercise over and above the Preferred Shares and other
         capital stock or securities of the Company, if any, issuable upon such
         exercise on the basis of the Purchase Price in effect prior to such
         adjustment; provided, however, that the Company shall deliver to such
         holder a due bill or other appropriate instrument evidencing such
         holder's right to receive such additional shares upon the occurrence
         of the event requiring such adjustment.

                 (m)     Anything in this Section 11 to the contrary
         notwithstanding, the Company shall be entitled to make such reductions
         in the Purchase Price, in addition to those adjustments expressly
         required by this Section 11, as and to the extent that it in its sole
         discretion shall determine to be advisable in order that any
         consolidation or subdivision of the Preferred Shares, issuance wholly
         for cash of any Preferred Shares at less than the current market
         price, issuance wholly for cash of Preferred Shares or securities
         which by their terms are convertible into or exchangeable for
         Preferred Shares, dividends on Preferred Shares payable in Preferred
         Shares or issuance of rights, options or warrants referred to in
         Section 11(b), hereafter made by the Company to holders of its
         Preferred Shares shall not be taxable to such stockholders.

                 (n)     In the event that at any time after the date of this
         Agreement and prior to the Shares Acquisition Date, the Company shall
         (i) declare or pay any dividend on the Common Shares payable in Common
         Shares or (ii) effect a subdivision, combination or consolidation of
         the Common Shares (by reclassification or otherwise than by payment of
         dividends in Common Shares) into a greater or lesser number of Common
         Shares, then in any such case (i) the number of one one-hundredths of
         a Preferred Share purchasable after such event upon proper exercise of
         each Right shall be determined by multiplying the number of one
         one-hundredths of a Preferred Share so purchasable immediately prior
         to such event by a fraction, the numerator of which is the number of
         Common Shares outstanding immediately before such event and the
         denominator of which is the number of Common Shares outstanding
         immediately after such event, and (ii) each Common Share outstanding
         immediately after such event shall have issued with respect to it that
         number of Rights which each Common Share outstanding immediately prior
         to such event had issued with respect to it.  The adjustments provided
         for in this Section 11(n) shall be made successively whenever such a
         dividend is declared or paid or such a subdivision, combination or
         consolidation is effected.

         Section 12.     Certificate of Adjusted Purchase Price or Number of
Shares.  Whenever an adjustment is made as provided in Section 11 and 13
hereof, the Company shall promptly (a)





                                       19
<PAGE>   23





prepare a certificate setting forth such adjustment, and a brief statement of
the facts accounting for such adjustment, (b) file with the Rights Agent and
with each transfer agent for the Common Shares or the Preferred Shares a copy
of such certificate and (c) mail a brief summary thereof to each holder of a
Rights Certificate in accordance with Section 25 hereof.

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

                 (a)     If, after the Shares Acquisition Date, directly or
         indirectly, (w) the Company shall consolidate with, or merge with and
         into, any other Person, (x) any Person shall consolidate with the
         Company, or merge with and into the Company and the Company shall be
         the continuing or surviving corporation of such merger and, in
         connection with such merger or consolidation all or part of the
         outstanding Common Shares are changed into or exchanged for stock or
         other securities of any other Person (or the Company) or cash or any
         other property, (y) the Company shall sell, mortgage or otherwise
         transfer (or one or more of its Subsidiaries shall sell, mortgage or
         otherwise transfer), in one or more transactions, assets or earning
         power aggregating 50% or more of the assets or earning power of the
         Company and its Subsidiaries (taken as a whole) to any Person other
         than the Company or one or more of its wholly-owned Subsidiaries, or
         (z) any Acquiring Person or any Associate or Affiliate of any such
         Acquiring Person, at any time after the date of this Agreement,
         directly or indirectly, (A) shall, in one transaction or a series of
         transactions, transfer any assets to the Company or to any of its
         Subsidiaries in exchange (in whole or in part) for Common Shares, for
         shares of other equity securities of the Company or for securities
         exercisable for or convertible into shares of equity securities of the
         Company (Common Shares or otherwise) or otherwise obtain from the
         Company, with or without consideration, any additional shares of such
         equity securities or securities exercisable for or convertible into
         shares of such equity securities (other than pursuant to a pro rata
         distribution to all holders of Common Shares), (B) shall sell,
         purchase, lease, exchange, mortgage, pledge, transfer or otherwise
         acquire or dispose of assets, in one transaction or a series of
         transactions, to, from or with the Company or any of its Subsidiaries
         without obtaining a written opinion from a nationally recognized
         investment banking firm that the terms of such transaction or
         arrangement are no less favorable to the Company than the Company
         would be able to obtain in arm's- length negotiation with an
         unaffiliated third party, (C) shall sell, purchase, lease, exchange,
         mortgage, pledge, transfer or otherwise acquire or dispose of in one
         transaction or a series of transactions, to, from or with the Company
         or any of the Company's Subsidiaries (other than incidental to the
         lines of business, if any, engaged in as of the date hereof between
         the Company and such Acquiring Person or Associate or Affiliate)
         assets having an aggregate fair market value of more than $5,000,000,
         (D) shall receive any compensation from the Company or any of the
         Company's Subsidiaries other than compensation for full-time
         employment as a regular employee at rates in accordance with the
         Company's (or its Subsidiaries') past practices, or (E) shall receive
         the benefit, directly or indirectly (except proportionately as a
         stockholder and except if resulting from a requirement of law or
         governmental regulation), of any loans, advances, guarantees, pledges
         or other financial assistance or





                                       20
<PAGE>   24





         any tax credits or other tax advantage provided by the Company or any
         of its Subsidiaries, then, and in each such case, (i) each holder of a
         Right (except as otherwise provided herein) shall thereafter have the
         right to receive, upon the exercise thereof at a price equal to the
         then current Purchase Price multiplied by the number of one
         one-hundredths of a Preferred Share for which a Right is then
         exercisable in accordance with the terms of this Agreement, and in
         lieu of Preferred Shares, such number of validly authorized and
         issued, fully paid, non-assessable and freely tradeable Common Shares
         of the Principal Party (as hereinafter defined) not subject to any
         liens, encumbrances, rights of first refusal or other adverse claims,
         as shall equal the result obtained by (A) multiplying the then current
         Purchase Price by the number of one one-hundredths of a Preferred
         Share for which a Right is then exercisable and dividing that product
         by (B) 50% of the then current per share market price of the Common
         Shares of the Principal Party (determined pursuant to Section 11(d)
         hereof) on the date of consummation 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 Company pursuant to
         this Agreement; (iii) the term "Company" shall thereafter be deemed to
         refer to such Principal Party; and (iv) such Principal Party shall
         take such steps (including, but not limited to, the reservation of a
         sufficient number of its Common Shares in accordance with Section 9
         hereof) 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 the Common Shares
         thereafter deliverable upon the exercise of the Rights.

                 (b)     "Principal Party" shall mean:

                         (i)      In the case of any transaction described in
                 (w) or (x) of the first sentence of Section 13(a), the Person
                 that is the issuer of any securities into which Common Shares
                 of the Company are converted in such merger or consolidation,
                 and if no securities are so issued, the Person that is the
                 surviving entity of such merger or consolidation (including
                 the Company if applicable); and

                         (ii)     in the case of any transaction described in
                 (y) or (z) of the first sentence in Section 13(a), the Person
                 that is the party receiving the greatest portion of the
                 assets, securities, earning power or other benefit transferred
                 pursuant to such transaction or transactions;

         provided, however, that in any such case described in clauses (b)(i)
         and (b)(ii):  (1) if the Common Shares of such Person are not at such
         time and have not been continuously over the preceding 12-month period
         registered under Section 12 of the Exchange Act, and such Person is a
         direct or indirect Subsidiary of another Person the Common Shares of
         which are and have been so registered, "Principal Party" shall refer
         to such other Person; (2) in case such Person is a Subsidiary,
         directly or indirectly, of more than one person, the Common Shares of
         two or more of which are and have been so registered,





                                       21
<PAGE>   25





         "Principal Party" shall refer to whichever of such Persons is the
         issuer of the Common Shares having the greatest aggregate market
         value; and (3) in case 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 (1)
         and (2) above shall apply to each of the chains of ownership having an
         interest in such joint venture as if such party were a "Subsidiary" of
         both or all of such joint venturers and the Principal Parties in each
         such chain shall bear the obligations set forth in this Section 13 in
         the same ratio as their direct or indirect interests in such Person
         bear to the total of such interests.

                 (c)     The Company shall not consummate any such
         consolidation, merger, sale or transfer unless the Principal Party
         shall have sufficient Common Shares authorized to permit the full
         exercise of the Rights and prior thereto the Company and such
         Principal Party shall have executed and delivered to the Rights Agent
         a supplemental agreement providing for the terms set forth in
         paragraphs (a) and (b) of this Section 13 and further providing that,
         as soon as practicable after the date of any consolidation, merger,
         sale or transfer mentioned in paragraph (a) of this Section 13, the
         Principal Party will:

                         (i)      prepare and file a registration statement
                 under the Act, with respect to the Rights and the securities
                 purchasable upon exercise of the Rights on an appropriate
                 form, and will use its best efforts to cause such registration
                 statement to (A) become effective as soon as practicable after
                 such filing and (B) remain effective (with a prospectus at all
                 times meeting the requirements of the Act) until the Final
                 Expiration Date;

                         (ii)     deliver to holders of the Rights historical
                 financial statements for the Principal Party and each of its
                 Affiliates which comply in all respects with the requirements
                 for registration on Form 10 under the Exchange Act; and

                         (iii)    take such actions as may be necessary or
                 appropriate under the blue sky laws of the various states.

                 The Company shall not enter into any transaction of the kind
         referred to in this Section 13 if at the time of such transaction
         there are any rights, warrants, instruments or securities outstanding
         or any agreements or arrangements which, as a result of the
         consummation of such transaction, would eliminate or substantially
         diminish the benefits intended to be afforded by the Rights.  The
         provisions of this Section 13 shall similarly apply to successive
         mergers, consolidations, sales or transfers.

         Section 14.     Fractional Rights and Fractional Shares.

                 (a)     The Company shall not be required to issue fractions
         of Rights or to distribute Rights Certificates which evidence
         fractional Rights.  In lieu of such fractional Rights, there shall be
         paid to the registered holders of the Rights Certificates with regard





                                       22
<PAGE>   26





         to which such fractional Rights would otherwise be issuable, an amount
         in cash equal to the same fraction of the current market value of a
         whole Right.  For the purposes of this Section 14(a), the current
         market value of a whole Right shall be the closing price of the Rights
         for the Trading Day immediately prior to the date on which such
         fractional Rights would have been otherwise issuable.  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
         principal consolidated transaction reporting system with respect to
         securities listed or admitted to trading on the principal national
         securities exchange on which the Rights are listed or admitted to
         trading or, if the Rights are not listed or admitted to trading on any
         national securities exchange, 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 Nasdaq or such other system
         then in use, or, if on any such date the Rights are not quoted by any
         such organization, the average of the closing bid and asked prices as
         furnished by a professional market maker making a market in the Rights
         selected by the Board of Directors of the Company.  If on any such
         date no such market maker is making a market in the Rights, the fair
         value of the Rights on such date as determined in good faith by the
         Board of Directors of the Company shall be used.

                 (b)     The Company shall not be required to issue fractions
         of Preferred Shares (other than fractions which are integral multiples
         of one one-hundredth of a Preferred Share) upon exercise of the Rights
         or to distribute certificates which evidence fractional Preferred
         Shares (other than fractions which are integral multiples of one
         one-hundredth of a Preferred Share).  Fractions of Preferred Shares in
         integral multiples of one one-hundredth of a Preferred Share may, at
         the election of the Company, be evidenced by depositary receipts,
         pursuant to an appropriate agreement between the Company and a
         depositary selected by it; provided, that such agreement shall provide
         that the holders of such depositary receipts shall have all the
         rights, privileges and preferences to which they are entitled as
         beneficial owners of the Preferred Shares represented by such
         depositary receipts.  In lieu of fractional Preferred Shares that are
         not integral multiples of one one-hundredth of a Preferred Share, the
         Company shall pay to the registered holders of Rights Certificates at
         the time such Rights are exercised as herein provided an amount in
         cash equal to the same fraction of the current market value of one
         Preferred Share.  For the purposes of this Section 14(b), the current
         market value of a Preferred Share shall be the closing price of a
         Preferred Share (as determined pursuant to the second sentence of
         Section 11(d)(i) hereof) for the Trading Day immediately prior to the
         date of such exercise.

                 (c)     Following the occurrence of a Distribution Date, the
         Company shall not be required to issue fractions of shares of Common
         Stock upon exercise of the Rights or to distribute certificates which
         evidence fractional shares of Common Stock.  In lieu of fractional
         shares of Common Stock, the Company may pay to the registered holders
         of Rights Certificates at the time such Rights are exercised as herein
         provided an amount in cash equal to the same fraction of the current
         market value of one share of Common





                                       23
<PAGE>   27





         Stock.  For purposes of this Section 14(c), the current market value
         of one share of Common Stock shall be the closing price of one share
         of Common Stock (as determined pursuant to the second sentence of
         Section 11(d)(i) hereof) for the Trading Day immediately prior to the
         date of such exercise.

                 (d)     The holder of a Right by the acceptance of the Right
         expressly waives his right to receive any fractional Rights or any
         fractional shares upon exercise of a Right (except as provided above).

         Section 15.     Rights of Action.  All rights of action in respect of
this Agreement, excepting the rights of action given to the Rights Agent under
Section 18 hereof, are vested in the respective registered holders of the
Rights Certificates (and, prior to the Distribution Date, the registered
holders of the Common Shares); and any registered holder of any Rights
Certificate (or, prior to the Distribution Date, of the Common Shares), without
the consent of the Rights Agent or of the holder of any other Rights
Certificate (or, prior to the Distribution Date, of the Common Shares), may, in
his own behalf and for his own benefit, enforce, and may institute and maintain
any suit, action or proceeding against the Company to enforce, or otherwise act
in respect of, his right to exercise the Rights evidenced by such Rights
Certificate in the manner provided in such Rights 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 Rights Holders.  Every holder of a Right,
by accepting the same, consents and agrees with the Company and the Rights
Agent and with every other holder of a Right that:

                 (a)     prior to the Distribution Date, the Rights will be
         transferable only in connection with the transfer of the Common
         Shares;

                 (b)     after the Distribution Date, the Rights Certificates
         will be transferable only on the registry books of the Rights Agent if
         surrendered at the principal office of the Rights Agent, duly endorsed
         or accompanied by a proper instrument of transfer and with appropriate
         forms and certificates fully executed;

                 (c)     the Company and the Rights Agent may deem and treat
         the Person in whose name the Rights Certificate (or, prior to the
         Distribution Date, the associated certificate for Common Shares) is
         registered as the absolute owner thereof and of the Rights evidenced
         thereby (notwithstanding any notations of ownership or writing on the
         Rights Certificates or the associated certificate for Common Shares
         made by anyone other than the Company or the Rights Agent) for all
         purposes whatsoever, and neither the Company nor the Rights Agent
         shall be affected by any notice to the contrary; and





                                       24
<PAGE>   28





                 (d)     notwithstanding anything in this Agreement to the
         contrary, neither the Company nor the Rights Agent shall have any
         liability to any holder of a Right or any other Person as a result of
         its inability to perform any of its obligations under this Agreement
         by reason of any preliminary or permanent injunction or other order,
         decree or ruling issued by a court of competent jurisdiction or by a
         governmental, regulatory or administrative agency or commission, or
         any statute, rule, regulation or executive order promulgated or
         enacted by any governmental authority prohibiting or otherwise
         restraining performance of such obligation.

         Section 17.     Rights Certificate Holder Not Deemed a Stockholder.
No holder, as such, of any Rights Certificate shall be entitled to vote,
receive dividends or be deemed for any purpose the holder of the Preferred
Shares or any other securities of the Company which may at any time be issuable
on the exercise of the Rights represented thereby, nor shall anything contained
herein or in any Rights Certificate be construed to confer upon the holder of
any Rights Certificate, as such, any of the rights of a stockholder of the
Company 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 to receive notice of meetings or other
actions affecting stockholders (except as provided in Section 25 hereof), or to
receive dividends or subscription rights, or otherwise, until the Right or
Rights evidenced by such Rights Certificate shall have been exercised in
accordance with the provisions hereof.

         Section 18.     Concerning the Rights Agent.  The Company 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 Company 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 by the Rights Agent in connection with the
acceptance and administration of this Agreement, including the costs and
expenses of defending against any claim of liability arising, directly or
indirectly, therefrom.  In no case shall the Rights Agent be liable for
special, indirect, incidental or consequential loss or damage of any kind
whatsoever (including but not limited to lost profits), even if the Rights
Agent has been advised of the possibility of such loss or damage.

         The Rights Agent shall be protected 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 Rights
Certificate or certificate for the Preferred Shares or Common Shares or for
other securities of the Company, 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, or otherwise upon the advice of counsel as set
forth in Section 20 hereof.

         Section 19.     Merger or Consolidation or Change of Name of Rights
Agent.  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
stock transfer or corporate trust 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 Rights
Certificates so countersigned; and in case at that time any of the Rights
Certificates shall not have been countersigned, any successor Rights Agent may
countersign such Rights 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 Rights Certificates shall have the full force provided in the Rights
Certificates and in this Agreement.

         In case at any time the name of the Rights Agent shall be changed and
at such time any of the Rights Certificates shall have been countersigned but
not delivered, the Rights Agent may adopt the countersignature under its prior
name and deliver Rights Certificates so countersigned; and in case at that time
any of the Rights Certificates shall not have been countersigned, the Rights
Agent may countersign such Rights Certificates either in its prior name or in
its changed name; and in all such cases such Rights Certificates shall have the
full force provided in the Rights 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 Company and the holders of Rights
Certificates, by their acceptance thereof, shall be bound:

                 (a)     The Rights Agent may consult with legal counsel (who
         may be legal counsel for the Company), 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 Company 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 any one of the Chairman of the Board, the Chief
         Executive Officer, the President, any Vice President, the Treasurer or
         the Secretary of the Company and delivered to the Rights Agent; and
         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.

<PAGE>   30





                 (c)     The Rights Agent shall be liable hereunder to the
         Company and any other Person only for its own 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 Rights 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 Company
         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 Rights Certificate
         (except its countersignature thereof); nor shall it be responsible for
         any breach by the Company of any covenant or condition contained in
         this Agreement or in any Rights Certificate; nor shall it be
         responsible for any change in the exercisability of the Rights
         (including the Rights becoming void pursuant to Section 11(a)(ii)
         hereof) or any adjustment in the terms of the Rights (including the
         manner, method or amount thereof) provided for in Section 3, 11, 13,
         23 or 24, or the ascertaining of the existence of facts that would
         require any such change or adjustment (except with respect to the
         exercise of Rights evidenced by Rights Certificates after actual
         notice that such change or adjustment is required); nor shall it by
         any act hereunder be deemed to make any representation or warranty as
         to the authorization or reservation of any Preferred Shares (or Common
         Shares and/or other securities, as the case may be) to be issued
         pursuant to this agreement or any Rights Certificate or as to whether
         any Preferred Shares (or Common Shares and/or other securities, as the
         case may be) will, when issued, be validly authorized and issued,
         fully paid and nonassessable.

                 (f)     The Company 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 this Agreement.

                 (g)     The Rights Agent is hereby authorized and directed to
         accept, prior to the Shares Acquisition Date, instructions with
         respect to the performance of its duties hereunder from any one of the
         Chairman of the Board, the Chief Executive Officer, the President, any
         Vice President, the Secretary or the Treasurer of the Company, 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 by it in good faith in accordance with instructions of any
         such officer or for any delay in acting while waiting for those
         instructions.

                 (h)     The Rights Agent and any stockholder, director,
         officer or employee of the Rights Agent may buy, sell or deal in any
         of the Rights or other securities of the Company, or become
         pecuniarily interested in any transaction in which the Company





                                       27
<PAGE>   31





         may be interested, or contract with or lend money to the Company or
         otherwise act as fully and freely as though it were not Rights Agent
         under this Agreement.  Nothing herein shall preclude the Rights Agent
         from acting in any other capacity for the Company 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 Company resulting from any such act, default, neglect or
         misconduct, provided reasonable care was exercised in the selection
         and continued employment thereof.

         Section 21.     Change of Rights Agent.  The Rights Agent or any
successor Rights Agent may resign and thereafter be discharged from its duties
under this Agreement upon 30 days' notice in writing mailed to the Company and
to each transfer agent of the Common Shares or Preferred Shares by registered
or certified mail, and to the holders of the Rights Certificates by first-class
mail.  The Company may remove the Rights Agent or any successor Rights Agent
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 Shares or
Preferred Shares by registered or certified mail, and to the holders of the
Rights Certificates by first-class mail.  If the Rights Agent shall resign or
be removed or shall otherwise become incapable of acting, the Company shall
appoint a successor to the Rights Agent.  If the Company shall fail to make
such appointment within a period of 30 days after giving notice of 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 Rights
Certificate (who shall, with such notice, submit his Rights Certificate for
inspection by the Company), then the registered holder of any Rights
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 Company or by such a court, shall be either (A) a corporation
organized and doing business under the laws of the United States or of any
state of the United States, in good standing, authorized under such laws to
exercise corporate trust or stock transfer powers, and subject to supervision
or examination by federal or state authority and which has at the time of its
appointment as Rights Agent a combined capital and surplus of at least $50
million or (B) an affiliate of such a corporation.  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 Company shall file notice thereof in writing with the
predecessor Rights Agent and each transfer agent of the Common Shares or
Preferred Shares, and mail a notice thereof in writing to the registered
holders of the Rights 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.

         Section 22.     Issuance of New Rights Certificates.  Notwithstanding
any of the provisions of this Agreement or of the Rights to the contrary, the
Company may, at its option, issue new Rights Certificates evidencing Rights in
such form as may be approved by its Board of Directors to reflect any
adjustment or change in the Purchase Price and the number or kind or class of
shares or other securities or property purchasable under the Rights
Certificates made in accordance with the provisions of this Agreement.

         Section 23.     Redemption.

                 (a)     The Rights may be redeemed by action of the Board of
         Directors pursuant to paragraph (b) of this Section 23 and shall not
         be redeemed in any other manner.

                 (b)     The Board of Directors of the Company may, at its
         option, at any time prior to such time as any Person becomes an
         Acquiring Person, redeem all, but not less than all, of the then
         outstanding Rights at a redemption price of $.01 per Right,
         appropriately adjusted to reflect any stock split, stock dividend or
         similar transaction occurring after the date hereof (such redemption
         price being hereinafter referred to as the "Redemption Price").  The
         redemption of the Rights by the Board of Directors may be made
         effective at such time on such basis and with such conditions as the
         Board of Directors in its sole discretion may establish.  If
         redemption of the Rights is to be effective as of a future date, the
         Rights shall continue to be exercisable, subject to Section 11(a)(ii)
         hereof, until the effective date of the redemption, provided that
         nothing contained herein shall preclude the Board of Directors from
         subsequently causing the Rights to be redeemed at a date earlier than
         the previously scheduled effective date of the redemption.  The
         Company may, at its option, pay the Redemption Price in cash, Common
         Shares (based on the current per share market price of the Common
         Shares at the time of redemption) or any other form of consideration
         deemed appropriate by the Board of Directors.

                 (c)     Immediately upon the action of the Board of Directors
         of the Company ordering the redemption of the Rights pursuant to
         paragraph (b) of this Section 23 (or at the effective time of such
         redemption established by the Board of Directors of the Company
         pursuant to paragraph (b) of this Section 23), and without any further
         action and without any notice, the right to exercise the Rights will
         terminate and the only right thereafter of the holders of Rights shall
         be to receive the Redemption Price.  The Company shall promptly give
         public notice of any such redemption; provided, however, that the
         failure to give, or any defect in, any such notice shall not affect
         the validity of such redemption.  Within 10 days after such action of
         the Board of Directors ordering the redemption of the Rights pursuant
         to paragraph (b) of this Section 23 or if later, the effectiveness of
         the redemption of the rights pursuant to the last sentence of
         paragraph (b), the Company shall mail a notice of redemption to all
         the holders of the then outstanding Rights 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 Shares.  Any notice which is mailed in the manner herein





                                       29
<PAGE>   33





         provided shall be deemed given, whether or not the holder receives the
         notice.  Each such notice of redemption will state the method by which
         the payment of the Redemption Price will be made.  The Company may, at
         its option, discharge all of its obligations with respect to the
         Rights by (i) issuing a press release announcing the manner of
         redemption of the Rights, (ii) depositing with a bank or trust company
         having a capital and surplus of at least $100 million, funds necessary
         for such redemption, in trust, to be applied to the redemption of the
         Rights so called for redemption and (iii) arranging for the mailing of
         the Redemption Price to the registered holders of the Rights; then,
         and upon such action, all outstanding Rights Certificates shall be
         null and void without further action by the Company.  Neither the
         Company nor any of its Affiliates or Associates may redeem, acquire or
         purchase for value any Rights at any time in any manner other than
         that specifically set forth in this Section 23 or in Section 24
         hereof, and other than in connection with the purchase of Common
         Shares prior to the Shares Acquisition Date.

         Section 24.     Exchange.

                 (a)     The Board of Directors of the Company 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 void pursuant to the
         provisions of Section 11(a)(ii) hereof) for Common Shares at an
         exchange ratio of one Common Share per Right, appropriately adjusted
         to reflect any stock split, stock dividend or similar transaction
         occurring after the date hereof.  Notwithstanding the foregoing, the
         Board of Directors shall not be empowered to effect such exchange at
         any time after any Person (other than the Company, any Subsidiary of
         the Company, any employee benefit plan of the Company or any such
         Subsidiary, or any entity holding Common Shares for or pursuant to the
         terms of any such plan), together with all Affiliates and Associates
         of such Person, becomes the Beneficial Owner of 50% or more of the
         Common Shares then outstanding.

                 (b)     Immediately upon the action of the Board of Directors
         of the Company ordering the exchange of any Rights pursuant to
         subsection (a) of this Section 24 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 Common Shares equal to the number of valid
         Rights held by such holder.  The Company 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 Company 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 state the method by which the exchange of the
         Common Shares 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





                                       30
<PAGE>   34





         number of Rights (other than Rights which have become void pursuant to
         the provisions of Section 11(a)(ii) hereof) held by each holder of
         Rights.

                 (c)     In any exchange pursuant to this Section 24, the
         Company, at its option, may substitute Preferred Shares (or equivalent
         preferred shares, as such term is defined in Section 11(b) hereof) for
         Common Shares exchangeable for Rights, at the initial rate of one
         one-hundredth of a Preferred Share (or equivalent preferred share) for
         each Common Share, as appropriately adjusted to reflect adjustments in
         the voting rights of the Preferred Shares pursuant to the terms
         thereof, so that the fraction of a Preferred Share delivered in lieu
         of each Common Share shall have the same voting rights as one Common
         Share.

                 (d)     In the event that there shall not be sufficient Common
         Shares or Preferred Shares issued but not outstanding or authorized
         but unissued to permit any exchange of Rights as contemplated in
         accordance with this Section 24, the Company shall take all such
         action as may be necessary to authorize additional Common Shares or
         Preferred Shares for issuance upon exchange of the Rights.

                 (e)     The Company shall not be required to issue fractions
         of Common Shares or to distribute certificates which evidence
         fractional Common Shares.  In lieu of such fractional Common Shares,
         the Company shall pay to the registered holders of the Rights
         Certificates with regard to which such fractional Common Shares would
         otherwise be issuable an amount in cash equal to the same fraction of
         the current market value of a whole Common Share.  For the purposes of
         this paragraph (e), the current market value of a whole Common Share
         shall be the closing price of a Common Share (as determined pursuant
         to the second sentence of Section 11(d)(i) hereof) for the Trading Day
         immediately prior to the date of exchange pursuant to this Section 24.

         Section 25.     Notice of Certain Events.

                 (a)     In case the Company shall propose (i) to pay any
         dividend payable in stock of any class to the holders of its Preferred
         Shares or to make any other distribution to the holders of its
         Preferred Shares (other than a regular quarterly cash dividend), (ii)
         to offer to the holders of its Preferred Shares rights or warrants to
         subscribe for or to purchase any additional Preferred Shares or shares
         of stock of any class or any other securities, rights or options,
         (iii) to effect any reclassification of its Preferred Shares (other
         than a reclassification involving only the subdivision of outstanding
         Preferred Shares), (iv) to effect any consolidation or merger into or
         with, 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 50% or more of the assets or earning power of
         the Company and its Subsidiaries (taken as a whole) to, any other
         Person, (v) to effect the liquidation, dissolution or winding up of
         the Company, or (vi) to declare or pay any dividend on the Common
         Shares payable in Common Shares or to effect a subdivision,
         combination or consolidation of the Common Shares (by reclassification
         or otherwise),





                                       31
<PAGE>   35





         then, in each such case, the Company shall give to each holder of a
         Rights Certificate, in accordance with Section 26 hereof, a notice of
         such proposed action, which shall specify the record date for such
         event, and the date of participation therein by the holders of the
         Common Shares and/or Preferred Shares, 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 the Preferred Shares 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 the Common
         Shares and/or Preferred Shares, whichever shall be the earlier.

                 (b)     In case any of the events set forth in Section
         11(a)(ii) hereof shall occur, then the Company shall as soon as
         practicable thereafter give to each holder of a Rights Certificate, in
         accordance with Section 26 hereof, a notice of the occurrence of such
         event, which notice shall describe such event and the consequences of
         such event to holders of Rights under Section 11(a)(ii) hereof.

         Section 26.     Notices.  Notices or demands authorized by this
Agreement to be given or made by the Rights Agent or by the holder of any

which the Company may deem necessary or desirable, any such supplement or

         Section 28.     Determination and Actions by the Board of Directors,

                          SOURCE SERVICES CORPORATION

                        (Pursuant to Section 151 of the
                       Delaware General Corporation Law)

                  ------------------------------------------


         Source Services Corporation, a corporation organized and existing
under the General Corporation Law of the State of Delaware (hereinafter called
the "Company"), hereby certifies that the following resolution was adopted by
the Board of Directors of the Company as required by Section 151 of the General
Corporation Law at a meeting duly called and held on May 28, 1997:

         RESOLVED, that pursuant to the authority granted to and vested in the
Board of Directors of this Company (hereinafter called the "Board of Directors"
or the "Board") in accordance with the provisions of the Restated Certificate
of Incorporation, the Board of Directors hereby creates a series of Preferred
Stock, par value $.01 per share (the "Preferred Stock"), of the Company and
hereby states the designation and number of shares, and fixes the relative
rights, preferences, and limitations thereof as follows:

         Series A Junior Participating Preferred Stock:

         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 the Series A
Preferred Stock shall initially be [___________].  Such number of shares may be
increased or decreased by resolution of the Board of Directors; provided, that
no decrease shall reduce the number of shares of Series A Preferred Stock to a
number less than the number of shares then outstanding plus the number of
shares reserved for issuance upon the exercise of outstanding options, rights
or warrants or upon the conversion of any outstanding securities or rights
issued by the Company convertible into Series A Preferred Stock and further
provided that the Board of Directors shall increase the number of shares





                                      A-1
<PAGE>   40





constituting the Series A Preferred Stock to the extent necessary for the
Company to have available sufficient shares of such Series A Preferred Stock
available to fulfill all of the Company's obligations to holders of securities
and Rights of the Company.

         Section 2.      Dividends and Distributions.

                 (A)     Subject to the rights of the holders of any shares of
         any series of Preferred Stock (or any similar stock) ranking prior and
         superior to the Series A Preferred Stock with respect to dividends,
         the holders of shares of Series A Preferred Stock, in preference to
         the holders of Common Stock, par value $.02 per share (the "Common
         Stock"), of the Company, and of any other junior stock, shall be
         entitled to receive, when, as and if declared by the Board of
         Directors out of funds legally available for the purpose, dividends
         payable when and as dividends are declared on the Company's Common
         Stock in an amount, subject to the provision for adjustment
         hereinafter set forth, equal to 100 times the aggregate per share
         amount of all cash dividends, and 100 times the aggregate per share
         amount (payable in kind) of all non-cash dividends or other
         distributions, declared on the Company's Common Stock (except as
         provided in the next sentence).  In the event the Company shall at any
         time declare or pay any dividend on the Common Stock payable in shares
         of Common Stock, or effect a subdivision or combination or
         consolidation of the outstanding shares of Common Stock (by
         reclassification or otherwise than by payment of a dividend in shares
         of Common Stock) into a greater or lesser number of shares of Common
         Stock, then in each such case the amount to which holders of shares of
         Series A Preferred Stock were entitled immediately prior to such event
         under the preceding sentence shall be adjusted by multiplying such
         amount 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 Company shall declare a dividend or distribution
         on the Series A Preferred Stock as provided in paragraph (A) of this
         Section immediately after it declares a dividend or distribution on
         the Common Stock.

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

                 (A)     Each share of Series A Preferred Stock shall entitle
         the holder thereof to 100 votes on all matters submitted to a vote of
         the stockholders of the Company.

                 (B)     Except as otherwise provided herein, in any other
         Certificate of Designations creating a series of Preferred Stock or
         any similar stock, or by law, the holders of shares of Series A
         Preferred Stock and the holders of shares of Common Stock and any
         other capital stock of the Company having general voting rights shall
         vote together as one class on all matters submitted to a vote of
         stockholders of the Company.

                 (C)     Except as set forth herein, or as otherwise provided
         by law, holders of Series A Preferred Stock shall have no special
         voting rights and their consent shall not





                                      A-2
<PAGE>   41





         be required (except to the extent they are entitled to vote with
         holders of Common Stock as set forth herein) for taking any corporate
         action.

         Section 4.      Reacquired Shares.  Any shares of Series A Preferred
Stock purchased or otherwise acquired by the Company in any manner whatsoever
shall be retired and cancelled promptly after the acquisition thereof.  All
such shares shall upon their cancellation become authorized but unissued shares
of Preferred Stock and may be reissued as part of a new series of Preferred
Stock subject to the conditions and restrictions on issuance set forth herein,
in the Certificate of Incorporation, or in any other Certificate of
Designations creating a series of Preferred Stock or any similar stock or as
otherwise required by law.

         Section 5.      Liquidation, Dissolution or Winding Up.  Upon any
liquidation, dissolution or winding up of the Company, no distribution shall be
made (1) 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, prior thereto, the holders of shares of Series A
Preferred Stock shall have received an aggregate amount per share, subject to
the provision for adjustment hereinafter set forth, equal to 100 times the
aggregate amount to be distributed per share to holders of shares of Common
Stock.  In the event the Company shall at any time declare or pay any dividend
on the Common Stock payable in shares of Common Stock, or effect a subdivision
or combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the aggregate amount to which holders of shares of Series A Preferred
Stock were entitled immediately prior to such event under the proviso in clause
(1) of the preceding sentence shall be adjusted by multiplying such amount 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 6.      Consolidation, Merger, etc.  In case the Company 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 share of
Series A Preferred Stock shall at the same time be similarly exchanged or
changed into an amount per share, subject to the provision for adjustment
hereinafter set forth, equal to 100 times the aggregate amount of stock,
securities, cash and/or any other property (payable in kind), as the case may
be, into which or for which each share of Common Stock is changed or exchanged.
In the event the Company shall at any time declare or pay any dividend on the
Common Stock payable in shares of Common Stock, or effect a subdivision or
combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the amount set forth in the preceding sentence with respect to the
exchange or change of shares of Series A Preferred Stock shall be adjusted by
multiplying such amount 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.





                                      A-3

         Section 7.      No Redemption.  The shares of Series A Preferred Stock
shall not be redeemable.

         Section 8.      Rank.  The Series A Preferred Stock shall rank, with
respect to the payment of dividends and the distribution of assets, junior to
all series of any other class of the Company's Preferred Stock.

         Section 9.      Amendment.  The Restated Certificate of Incorporation
of the Company shall not be amended in any manner which would materially alter
or change the powers, preferences or special rights of the Series A Preferred
Stock so as to affect them adversely without the affirmative vote of the
holders of at least two-thirds of the outstanding shares of Series A Preferred
Stock, voting together as a single class.

         IN WITNESS WHEREOF, this Certificate of Designations is executed on
behalf of the Company by its Chairman of the Board on this ________ day of May,
1997.

Shares as constituted at such date.  As provided in the Rights Agreement, the
Purchase Price and the number of one one-hundredths of a Preferred Share which
may be purchased upon the exercise of the Rights evidenced by this Rights
Certificate are subject to modification and adjustment upon the happening of
certain events.

         This Rights Certificate is subject to all of the terms, provisions and
conditions of the Rights Agreement, which terms, provisions and conditions are
hereby incorporated herein by reference and made a part hereof and to which
Rights Agreement reference is hereby made for a full description of the rights,

evidencing Rights entitling the holder to purchase a like aggregate number of
Preferred Shares as the Rights evidenced by the Rights Certificate or Rights
Certificates surrendered shall have entitled such holder to purchase.  If this
Rights Certificate shall be exercised in part, the holder shall be entitled to

thereof a cash payment will be made, as provided in the Rights Agreement.

         No holder of this Rights Certificate shall be entitled to vote or
receive dividends or be deemed for any purpose the holder of the Preferred
Shares or of any other securities of the Company which may at any time be

receive notice of meetings or other actions affecting stockholders (except as
provided in the Rights Agreement), or to receive dividends or subscription

purpose until it shall have been countersigned by the Rights Agent.

                                                                      EXHIBIT C 


                         SUMMARY OF RIGHTS TO PURCHASE
                     PREFERRED SHARES UNDER PLAN ADOPTED BY
                          SOURCE SERVICES CORPORATION


         On May 28, 1997, the Board of Directors of Source Services Corporation
(the "Company") declared a dividend of one Right for each outstanding common
share (a "Right"), par value $.02 per share (the "Common Shares"), of the
Company.  The dividend is payable on June 18, 1997 (the "Record Date") to the
stockholders of record on that date.  Each Right entitles the registered holder
to purchase from the Company one one-hundredth of a share of Series A Junior
Participating Preferred Stock, par value $.01 per share (the "Preferred
Shares"), of the Company at a price of $90 per one one-hundredth of a Preferred
Share (the "Purchase Price"), subject to adjustment.  The description and terms
of the Rights are set forth in a Rights Agreement (the "Rights Agreement")
between the Company and ChaseMellon Shareholder Services L.L.C., as Rights
Agent (the "Rights Agent").

         Until the earlier of (i) the close of business on the tenth day after
the first public announcement that a person or group of affiliated or
associated persons have acquired beneficial ownership of 20% or more of the
outstanding Common Shares (an "Acquiring Person"), or (ii) the close of
business on the tenth day (or such later date as may be determined by action of
the Board of Directors prior to such time as any Person becomes an Acquiring
Person) following the commencement of, or announcement of an intention to make,
a tender offer or exchange offer the consummation of which would result in the
beneficial ownership of such person or group of 20% or more of such outstanding
Common Shares (the earlier of such dates being called the "Distribution Date"),
the Rights will be evidenced by the Common Share certificates, will be
transferable only by the transfer of the Common Shares associated with such
Rights and any transfer of the Common Shares (including a transfer to the
Company) will constitute a transfer of the Rights.  As described below, after a
person or group becomes an Acquiring Person, the Rights may not be redeemed or
amended.

         Until the Distribution Date (or earlier redemption or expiration of
the Rights), new Common Share certificates issued after the Record Date, upon
transfer or new issuance of Common Shares, will contain a legend incorporating
the Rights Agreement by reference.  Until the Distribution Date (or earlier
redemption or expiration of the Rights), the surrender for transfer of any
certificates for Common Shares outstanding as of the Record Date, even without
such notation or a copy of this Summary of Rights being attached, will also
constitute the transfer of the Rights associated with the Common Shares
represented by such certificate.  As soon as practicable following the
Distribution Date, separate certificates evidencing the Rights ("Rights
Certificates") will be mailed to holders of record of the Common Shares as of
the close of business on the Distribution Date and such separate Rights
Certificates alone will evidence the Rights.

         The Rights are not exercisable until a person, entity or group becomes
an Acquiring Person.  The Rights will expire on June 18, 2007 (the "Final
Expiration Date"), unless the Final





                                      C-1
<PAGE>   52





Expiration Date is extended or unless the Rights are redeemed earlier by the
Company, in each case, as described below.

         If a person or group of affiliated or associated persons becomes an
"Acquiring Person" by obtaining beneficial ownership of more than 20% of the
then outstanding Common Shares, each holder of a Right (other than those
described in the next sentence) will thereafter have the right to receive, upon
exercise, Common Shares (or, in certain circumstances, cash, property or other
securities of the Company) having a value equal to two times the Purchase Price
of the Right.  All Rights that are, or (under certain circumstances specified
in the Rights Agreement) were, beneficially owned by any Acquiring Person will
be void.

         At any time after the first date of public announcement by the Company
or an Acquiring Person than an Acquiring Person has become such (a "Shares
Acquisition Date"), if (i) the Company is the surviving corporation in a merger
with any other company or entity, (ii) the Company is acquired in a merger or
other business combination transaction, (iii) 50% or more of the Company's
consolidated assets or earning power are sold, or (iv) an Acquiring Person
engages in certain "self-dealing" transactions with the Company, each holder of
a Right (other than those whose rights have become void) will thereafter have
the right to receive, upon the exercise thereof at the then current Purchase
Price of the Right, that number of shares of common stock of the surviving or
acquiring company which at the time of such transaction will have a market
value of two times the exercise price of such Right.

         At any time after a person or group becomes an Acquiring Person and
prior to the acquisition by such person or group of 50% or more of the
outstanding Common Shares, the Board of Directors of the Company may exchange
the Rights (other than Rights owned by such person or group which have become
void), in whole or in part, without any additional payment, for Common Shares
at an exchange ratio of one Common Share (or of a share of a class or series of
the Company's preferred shares having equivalent rights, preferences and
privileges), per Right (subject to adjustment).

         With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments require an adjustment of at least 1% in
such Purchase Price.  No fractional Preferred Shares will be issued (other than
fractions which are integral multiples of one one-hundredth of a Preferred
Share, which may, at the election of the Company, be evidenced by depositary
receipts) and in lieu thereof, an adjustment in cash will be made based on the
market price of the Preferred Shares on the last trading day prior to the date
of exercise.

         At any time prior to the Shares Acquisition Date, the Board of
Directors of the Company may redeem all, but not less than all, of the Rights
at a price of $.01 per Right (the "Redemption Price").  The redemption of the
Rights may be made effective at such time, on such basis and with such
conditions as the Board of Directors in its sole discretion may establish.

         Immediately upon any 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.

         Any of the provisions of the Rights may be amended by the Board of
Directors of the Company prior to the Shares Acquisition Date.  After the
Shares Acquisition Date, the





                                      C-2
<PAGE>   53





provisions of the Rights Agreement may be amended by the Board in order to cure
any ambiguity or to make changes which do not adversely affect the interests of
holders of Rights (excluding the interests of any Acquiring Person).

         A copy of the Rights Agreement has been filed with the Securities and
Exchange Commission as an Exhibit to a Registration Statement on Form 8-A dated
__________________, 1997.  A copy of the Rights Agreement is available free of
charge from the Company.  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 hereby incorporated herein by reference.
