                      COMMON STOCK PIPES PURCHASE AGREEMENT

          THIS COMMON STOCK PIPES PURCHASE AGREEMENT (the "Agreement") is made
as of July 25, 2001, by and among P-COM, Inc., a Delaware corporation (the
"Company"), and the investors listed on Schedule A attached hereto (each an
"Investor" and collectively the "Investors").

                                    RECITALS:

          A. The Company desires to sell shares of the Company's Common
Stock, $.0001 par value ("Common Stock") to the Investors, and the Investors
desire to purchase shares of Common Stock, on the terms and subject to the
conditions set forth in this Agreement.

          THE PARTIES AGREE AS FOLLOWS:

   1.  Purchase and Sale of Common Stock.
       ---------------------------------

          1.1 Sale and Issuance of Common Stock. The Company shall sell to each
Investor and each Investor shall purchase from the Company, on the date of the
Closing (as defined in Section 1.2 below), at $0.79 per share (the "Share
Price"), that number of shares of Common Stock equal to the quotient of dollar
value of such Investor's investment as indicated on Schedule A divided by $0.79
(the "Shares"). The Investors acknowledge that this transaction and its pricing
are before, and do not reflect, the Company's proposed reverse stock split. The
parties acknowledge that the public market trading price of Common Stock is
below $0.79. The parties further acknowledge that the Investors' decision to
purchase at the Share Price is based upon the pro forma calculation of Adjusted
Net Tangible Book Value ("NTBV") per share shown on Exhibit N ("Exhibit N") to
the Disclosure Schedule. The parties agree that pro forma NTBV per share will be
recalculated (the "Revised NTBV") using the same formula as shown on Exhibit N
but using the information contained in the unaudited June 30, 2001 balance sheet
in P-COM's Form 10-Q (including any amendments thereto or restatements thereof
before March 31, 2002) for the period ending June 30, 2001; for purposes of such
recalculation, the $19,338,000 figure for discounted Convertible Subordinated
Notes shown on Exhibit N shall remain unchanged and Revised NTBV shall be
rounded up to the next highest cent. The number of shares issued to the
Investors pursuant to this Agreement shall thereafter be corrected as follows:
(A) if the Revised NTBV per share is less than the Share Price, P-COM shall
promptly issue to each Investor that number of shares of Common Stock equal to
the difference between (i) the number of shares issued to the Investor pursuant
to this Agreement at Closing and (ii) the number of shares of Common Stock equal
to the quotient of dollar value of such Investor's investment as indicated on
Schedule A divided by the Revised NTBV per share; (B) if the Revised NTBV per
share is greater than the Share Price, each Investor shall promptly return to
P-COM that number of shares of Common Stock equal to the difference between (i)
the number of shares issued to the Investor pursuant to this Agreement at
Closing and (ii) the number of shares of Common Stock equal to the quotient of
dollar value of such Investor's investment as indicated on Schedule A divided by
the Revised NTBV per share. The term "Shares" as used in
<PAGE>

this Agreement includes any additional shares of Common Stock issued to the
Investors by reason of the foregoing recalculation. P-COM warrants that the
unaudited June 30, 2001 balance sheet in its Form 10-Q for the period ending
June 30, 2001 (including any amendments thereto or restatements thereof) will be
accurate and complete in all material respects and will fairly present the
financial condition of the Company as of June 30, 2001 and be prepared in
accordance with GAAP, consistently applied, except that it may not be
accompanied by all footnotes required by GAAP and will be subject to normal
year-end audit adjustments.

          1.2 Closing. The purchase and sale of the Shares shall take place at
9:00 a.m. Pacific Daylight Time on July 31, 2001, at the offices of Brobeck,
Phleger & Harrison LLP, 2200 Geng Road, Palo Alto, California 94303, or on such
date and at such time and place as the Company and the Investors shall mutually
agree (the "Closing"). At the Closing the Company shall deliver to each Investor
a stock certificate representing the Shares purchased by it against delivery to
the Company by each Investor of the quantity of funds indicated adjacent to such
Investor's name on Schedule A by wire transfer to the Company.

   2.  Representations and Warranties of the Company. For purposes of this
       ---------------------------------------------
Section 2, unless the context otherwise requires, the term "Company" shall
include the Company and its subsidiaries (excluding RT Masts Ltd.) as listed in
its most recent Annual Report on Form 10-K for the year ended December 31, 2000
(the "Annual Report") filed with the Securities and Exchange Commission (the
"SEC"). Except as set forth in the Disclosure Schedule delivered to the
Investors supplementally (the "Disclosure Schedule"), the Company hereby
represents and warrants to the Investors as follows:

          2.1 Corporate Organization and Authority of the Company.  The Company
and each of its subsidiaries:

               (a) is a corporation duly organized, validly existing, authorized
to exercise all its corporate powers, rights and privileges and in good standing
in the state or jurisdiction of its incorporation;

               (b) has the corporate power and authority to own and operate its
properties and to carry on its business as presently conducted and as proposed
to be conducted; and

               (c) is qualified to do business as a foreign corporation in each
jurisdiction in which the ownership of its property or the nature of its
business requires such qualification, except where failure to so qualify would
not have a materially adverse effect on the business, properties or financial
condition of the Company and its subsidiaries, taken as a whole. The Company has
furnished to the Investors true and correct copies of its Certificate of
Incorporation and Bylaws, each as amended to date.

          2.2 Capitalization.  The authorized capital stock of the Company
consists of:

               (a) Preferred Stock. 2,000,000 shares of Preferred Stock, $.0001
                   ---------------
par value, 750,000 shares of which have been designated Series A Junior
Participating Preferred Stock, of which none were issued and outstanding as of
July 25, 2001.
<PAGE>

               (b) Common Stock. 145,000,000 shares of Common Stock, $.0001 par
                   ------------
value, of which 80,740,176 shares were issued and outstanding as of July 25,
2001.

               (c) All outstanding shares of the Company's Common Stock have
been duly authorized and validly issued (including, without limitation, issued
in compliance with applicable federal and state securities laws), and are fully
paid and nonassessable.

               (d) Since December 31, 2000, the Company has not issued any
shares of Common Stock or Preferred Stock except in connection with the exercise
of outstanding options. Except as described in the Disclosure Schedule, there
are no options, warrants, conversion privileges or other contractual rights
presently outstanding to purchase or otherwise acquire from the Company any
shares of the Company's capital stock or other securities (whether or not
authorized).

          2.3 Subsidiaries. The Company does not presently own, have any
investment in, or control, directly or indirectly, any subsidiaries,
associations or other business entities, except as disclosed in the Annual
Report. The Company is not a participant in any joint venture or partnership,
except as disclosed in the Annual Report.

          2.4 Authorization. All corporate action on the part of the Company,
its officers, directors and stockholders necessary for the authorization,
execution, delivery and performance by the Company of all its obligations under
this Agreement and for the authorization, issuance, sale and delivery of the
Shares has been taken, and this Agreement, once executed by the Company and each
Investor, will constitute a legally binding and valid obligation of the Company
enforceable in accordance with its terms, such enforceability being subject only
to laws of general application relating to bankruptcy, insolvency and the relief
of debtors and rules of law governing specific performance, injunctive relief or
other equitable remedies. Except for rights, if any, which have been duly
waived, the issuance and sale of the Shares will not give rise to any preemptive
rights or rights of first refusal on behalf of any person in existence on the
date hereof.

          2.5 Validity of Shares. The Shares, when issued, sold and delivered in
accordance with the terms and for the consideration expressed in this Agreement,
shall be duly and validly issued (including, without limitation, compliance with
applicable federal and state securities laws), fully paid and nonassessable, and
free and clear of all pledges, liens, encumbrances and restrictions other than
any liens or encumbrances created by or imposed on the holder thereof through no
action of the Company. Assuming the truth and accuracy of the representations
made by the Investors, the offer, sale and issuance of the Common Stock are
exempt from the registration requirements of the Securities Act and applicable
state securities Laws, and neither the Company nor any authorized agent acting
on its behalf has taken or will take any action hereafter that would cause the
loss of such exemption.

          2.6 No Conflict. The execution and delivery of this Agreement do not,
and the consummation of the transactions contemplated hereby will not, conflict
with, or result in any violation of, or default (with or without notice or lapse
in time, or both) under, or give rise to a right of termination, cancellation or
acceleration of any obligation or to a loss of a material benefit under, any
provision of the Certificate of Incorporation or Bylaws of the Company. The
<PAGE>

execution and delivery of this Agreement do not, and the consummation of the
transactions contemplated hereby will not, conflict with, or result in any
violation of, or default (with or without notice or lapse in time, or both)
under, or give rise to a right of termination, cancellation or acceleration of
any obligation or to a loss of a material benefit under, any provision of any
mortgage, indenture, lease or other agreement or instrument, permit, concession,
franchise, license, judgment, order, decree, statute, law, ordinance, rule or
regulation applicable to the Company, its properties or assets, the effect of
which could have a material adverse effect on the Company or materially impair
or restrict its power to perform its obligations as contemplated hereby.

          2.7 Accuracy of Reports. The Annual Report, the Company's quarterly
report on Form 10-Q for the quarter ended March 31, 2001 filed with the SEC (the
"Quarterly Report"), and all reports required to be filed by the Company
thereafter to the date of this Agreement under the Securities Exchange Act of
1934, as amended (the "Exchange Act"), copies of which have been furnished to
the Investors (together, the "SEC Reports"), have been duly filed, were (as
amended to date) complete and correct in all material respects as of the dates
at which the information was furnished, and (as amended to date) contained (as
of such dates) no untrue statement of a material fact nor omitted to state a
material fact necessary in order to make the statements made therein, in light
of the circumstances in which they were made, not misleading.

          2.8 Changes. Except as otherwise disclosed herein, in the Disclosure
Schedule or in the SEC Reports, between March 31, 2001 and the date of this
Agreement there has not been:

               (a) any change in the assets, liabilities, financial condition,
prospects or operations of the Company from that reflected in the Quarterly
Report, except changes in the ordinary course of business which have not been,
either in any individual case or in the aggregate, materially adverse;

               (b) any material change in the contingent obligations of the
Company, whether by way of guaranty, endorsement, indemnity, warranty or
otherwise;

               (c) any damage, destruction or loss, whether or not covered by
insurance, materially and adversely affecting the properties or business of the
Company;

               (d) any declaration or payment of any dividend or other
distribution of the assets of the Company;

               (e) any labor organization activity; or

               (f) to the best of the Company's knowledge, any other event or
condition of any character which has materially and adversely affected the
Company's assets, liabilities, financial condition, prospects or operations.

          In addition, no person or entity from which, as at June 30, 2001, the
Company had accounts receivable with a net carrying value of at least $1,000,000
was at June 30, 2001 or is now in bankruptcy proceedings as a result of filing a
voluntary bankruptcy petition or having an involuntary bankruptcy petition filed
against him/it.
<PAGE>

          2.9 Government Consent, etc. No consent, approval or authorization of
or designation, declaration or filing with any governmental authority or any
other person or entity on the part of the Company is required in connection with
the valid execution and delivery of this Agreement, or the offer, sale or
issuance of the Shares, or the consummation of any other transaction
contemplated hereby, except the filing of a Registration Statement and related
activities pursuant to Section 4 hereof.

          2.10 Full Disclosure. The representations and warranties of the
Company contained in this Agreement, when read together with the Disclosure
Schedule and the SEC Reports, do not contain any untrue statement of a material
fact or omit to state any material fact necessary in order to make the
statements contained herein, in light of the circumstances under which they were
made, not misleading.

          2.11 Conflicts Prohibited. The Company represents, warrants and
covenants that to the best of its knowledge no officer or employee of any
Investor has a direct or indirect economic interest in the Company or its
property or contracts other than as disclosed in the SEC Reports. The Company
represents, warrants and covenants that to the best of its knowledge no officer
or employee of any Investor shall receive, directly or indirectly, anything of
substantial economic value for his or her private benefit from the Company or
anyone acting on its behalf in connection with the investment made pursuant to
this Agreement.

          2.12 Intellectual Property. The Company has not violated and is not
currently in violation of any copyright, trademark or other intellectual
property rights of any third persons, except to the extent that such violation
does not materially and adversely affect the Company or its operations.

          2.13 Litigation/Bankruptcy/Malfeasance. The Company is not the subject
of and has not received notice of any legal proceedings of the following types
to which the Company is a party (or, if applicable, any executive officer or
director of the Company) or any of its property is the subject: any proceeding
that involves a claim against the Company for damages in excess of $500,000; any
material bankruptcy, receivership or similar proceedings with respect to the
Company; or any criminal proceedings or civil proceedings for fraud or
malfeasance of which a director or executive officer of the Company is the
subject (excluding minor offenses). The Company is not a plaintiff in any
material proceedings (other than others' bankruptcy proceedings) except a
lawsuit for approximately $1,500,000 filed against Technosystem and Banca di
Roma.

          2.14 Investment Company. The Company represents and warrants that it
is not an "investment company" or a company "controlled" by an "investment
company", within the meaning of the Investment Company Act of 1940, as amended
(the "1940 Act"). In addition, the Company agrees that it shall not become an
"investment company" or a company "controlled" by an "investment company",
within the meaning of the 1940 Act. In the event that the Company breaches the
foregoing, the Company shall forthwith notify the Investors and shall take
immediate corrective action to remedy such breach.

   3.  Representations and Warranties of the Investors. Each Investor severally,
       -----------------------------------------------
and not jointly, represents and warrants to the Company as follows:
<PAGE>

          3.1 Organization. It is validly existing under the laws of the state
(or country) in which it is chartered, with all requisite power and authority to
conduct its business as now being conducted.

          3.2 Authority. It has all corporate or partnership, as the case may
be, right, power and authority to enter into this Agreement and to consummate
the transactions contemplated hereby. The execution and delivery of this
Agreement by the Investor and the consummation by it of the transactions
contemplated hereby have been duly authorized by all necessary corporate or
partnership, as the case may be, action on behalf of the Investor. This
Agreement has been duly executed and delivered by and constitutes a legal, valid
and binding obligation of the Investor, enforceable in accordance with its
terms, subject to laws of general application relating to bankruptcy, insolvency
and the relief of debtors and rules of law governing specific performance,
injunctive relief or other equitable remedies. The execution and delivery of
this Agreement do not, and the consummation of the transactions contemplated
hereby will not, conflict with or result in any violation of any obligation
under any provision of the organizational or other charter documents of the
Investor or any judgment, order, decree, statute, law, ordinance, rule or
regulation applicable to the Investor.

          3.3 Information. The Investor represents that it has received all the
information it has requested from the Company and considers necessary or
appropriate for deciding whether to purchase the Shares. The delivery of any
information by the Company to the Investor shall not abrogate the
representations and warranties of the Company contained herein.

          3.4 No Current Resale. The Investor is acquiring the Shares for its
own account and not with a view to sale or distribution. Any such sale or
distribution shall be made only in compliance with the provisions of the
Securities Act of 1933, as amended (the "Securities Act") and all applicable
blue sky laws. The Investor acknowledges that the Shares are not now registered
under the Securities Act or any blue sky law, and might never be so registered
(although the Company has covenanted in Section 4.1 to file for and use its best
efforts to obtain such registration, by certain specified dates). The Investor
further acknowledges that the stock certificate representing the Shares will
bear a customary securities-law restrictive legend.

          3.5 Status of Investor (Regulation D). The Investor is an "accredited
investor" as such term is defined in Rule 501 as promulgated by the SEC under
the Securities Act.

   4.  Covenants.
       ---------

          4.1 Registration of Shares

               (a) The Company shall, before April 12, 2002, prepare and file
with the SEC a registration statement on Form S-3 under the Securities Act
covering the resale of the Shares by any Investor (the "Registration
Statement"), and corresponding applications for registration under the blue sky
laws of any states for which any Investor reasonably requests in writing to the
Company that the Company obtain such blue-sky registration (it being understood
that in the vast majority of states no such registration is legally required,
due to the Company's Nasdaq National Market listing or other reasons). The
Company shall use its best efforts to obtain effectiveness of the Registration
Statement and such blue sky registrations as soon
<PAGE>

thereafter as practicable, and in any event by April 25, 2002. The Company shall
use its best efforts to keep the Registration Statement and such blue sky
registrations effective after that. Notwithstanding the foregoing, the Company
will only be required to maintain the effectiveness of the Registration
Statement and such blue sky registrations until the earlier of (i) such time as
all of the Shares have been disposed of by the Investors, or (ii) such date on
which the Investors may legally dispose of all of the Shares in one transaction
in the open market pursuant to Rule 144(k) under the Securities Act. The Company
shall also cause the Shares to be listed on any National Market and on any stock
exchange on which the Common Stock may from time to time be listed. The Company
shall pay all fees and expenses incurred by the Company in connection with
preparing, filing, prosecuting and updating the Registration Statement, such
blue sky applications and registrations, and such listing, including all
registration and filing fees, listing fees, printing expenses, and fees and
disbursements of the Company's counsel and accountants.

               (b) Each Investor shall cooperate fully with the Company in the
preparation of such Registration Statement and blue sky applications and shall
provide to the Company all information and materials (including updated
information and materials) regarding itself and its proposed method of
disposition of the Shares and take all actions reasonably requested by the
Company to permit the Company to comply with applicable requirements of the SEC,
to comply with applicable requirements of the relevant blue sky laws, and to
obtain the desired acceleration of the effective date of such Registration
Statement.

               (c) Subject to Section 4.1(d) hereof, the Company shall promptly
prepare and file with the SEC and any relevant blue sky authorities such
amendments and supplements to the Registration Statement and the prospectus used
in connection therewith as may be necessary to keep such Registration Statement
effective and to comply with (and enable the Investors to comply with) the
provisions of the Securities Act and Rule 415 thereunder with respect to the
disposition of all the Shares.

               (d) During the effectiveness of the Registration Statement, the
Company shall promptly notify the Investors of the happening of any event or
other circumstance as the result of which, in the Company's judgment, (i) the
prospectus included in the Registration Statement, as then in effect, would
include an untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein
not misleading in light of the circumstances then existing, or (ii) the offer or
resale of the Shares would otherwise have a material and adverse effect on any
proposed or pending acquisition, merger, business combination or other material
transaction involving the Company; and, upon receipt of such notice and until
the earlier of (i) the date the Company makes available to the Investors a
supplemented or amended prospectus meeting the requirements of the Securities
Act and relevant blue sky laws, or (ii) the date the Company notifies the
Investors that the Investors may resume offers and sales using the prior
prospectus, the Investors shall not offer or sell any Shares pursuant to the
Registration Statement (and shall return all copies of such prior prospectus to
the Company if requested to do so by it). Notwithstanding Section 4.1(c), the
Company may continue such "blackout" period or periods for such period of time
as the Company considers reasonably necessary and in its best interest due to
circumstances then existing, or simply due to the fact that
amendments/supplements of a Registration Statement/ prospectus cannot be
prepared instantly; but in no event may the Company impose "blackouts" on the
Investors for any period of ten or more consecutive business days or totaling
more than 20 days in any 12
<PAGE>

month period (plus any "Permitted Blackouts" as defined in the Registration
Rights Agreement dated as of December 21, 1998 between the Company, Castle Creek
Technology Partners LLC and others).

               (e) The Company shall not be required to apply for or obtain blue
sky registration in any state if in connection therewith or as a condition
thereto it must (i) qualify to do business in such state where it would not
otherwise be required to qualify, (ii) subject itself to general taxation in
such state, (iii) file a general consent to service of process in such state, or
(iv) make any change in its Certificate of Incorporation or Bylaws, which the
Company's Board of Directors determines to be contrary to the best interests of
the Company and its stockholders.

               (f) Indemnification.
                   ---------------

               a. The Company will indemnify each Investor, and each of the
officers and directors of, and each person controlling, each Investor, against
all claims, losses, expenses, damages and liabilities (or actions in respect
thereto) arising out of or based on (A) any untrue statements (or alleged untrue
statement) of a material fact contained in any prospectus contained in any
registration statement covering the Shares for resale, or based on any omission
(or alleged omission) to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, or (B) any
misrepresentation or breach of any representation or warranty given or made by
the Company in this Agreement, and will reimburse each Investor, each of its
officers and directors and each person controlling each Investor, for any
reasonable legal and any other expenses incurred in connection with
investigating, defending or settling any such claim, loss, damage, liability or
action, provided that the Company will not be liable in any such case to the
extent that any such claim, loss, damage or liability is caused by any untrue
statement or omission based upon written information furnished to the Company by
such Investor specifically for use therein.

               b. Each Investor will indemnify the Company, each of its
directors and officers, and each person who controls the Company within the
meaning of the Securities Act, against all claims, losses, expenses, damages and
liabilities (or actions in respect thereof) arising out of or based on (A) any
untrue statement (or alleged untrue statement) of a material fact contained in
any such prospectus, or any omission (or alleged omission) to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, or (B) any sale of Shares which violates (or allegedly
violates) the Securities Act because of violation of the prospectus delivery
requirement or because more or less than the information in such prospectus is
given (or alleged to be given) in connection with the sale, or (C) any
misrepresentation or breach of any representation or warranty given or made by
such Investor in this Agreement, and will reimburse the Company, and such
directors, officers, or controlling persons, for any reasonable legal or any
other expenses incurred in connection with investigating, defending or settling
any such claim, loss, damage, liability or action, but in the case of subsection
(f)(ii)(A) to the extent, and only to the extent, that such untrue statement (or
alleged untrue statement) or omission (or alleged omission) is made in such
prospectus in reliance upon and in conformity with written information furnished
to the Company by such Investor specifically for use therein provided, however,
that the indemnity agreement contained in this section 4.1(f)(ii) shall not
apply to amounts paid in settlement of any such claims, losses, expenses,
damages and liabilities if such settlement is effected without the consent of
the
<PAGE>

Investor, which consent shall not be unreasonably withheld; provided,
further, that in no event shall any indemnity under this section 4.1(f)(ii)
exceed the net proceeds from the offering received by such Investor.

               c. Each party entitled to indemnification under this Section
4.1(f) (the "Indemnified Party") shall give notice to the party required to
provide indemnification (the "Indemnifying Party") promptly after such
indemnified party has actual knowledge of any claim as to which indemnity may be
sought, and shall permit the Indemnifying Party to assume the defense of any
such claim or any litigation resulting therefrom, provided that counsel for the
Indemnifying Party, who shall conduct the defense of such claim or litigation,
shall be approved by the Indemnified Party (whose approval shall not be
unreasonably withheld), and the Indemnified Party may participate in such
defense at the Indemnified Party's expense, and provided further that the
failure of any Indemnified Party to give notice as provided herein shall not
relieve the Indemnifying Party of its obligations hereunder, unless such failure
resulted in actual detriment to the Indemnifying Party. The Indemnified Party
shall provide all cooperation reasonably requested for the defense of the claim
or litigation. No Indemnifying Party, in the defense of any such claim or
litigation, shall, except with the consent of each Indemnified Party, consent to
entry of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party of a release from all liability in respect to such claim or
litigation. An Indemnified Party shall not decline any settlement complying with
the foregoing if it requires nothing of the Indemnified Party other than the
payment of money (which is in fact paid by the Indemnifying Party) and does not
include an admission of liability.

               d. In order to provide for just and equitable contribution to
joint liability under the Securities Act in any case in which any person or
entity entitled to indemnification under Section 4.1(f) makes a claim for
indemnification pursuant to this Section 4.1(f) but it is judicially determined
(by entry of a final judgment or decree by a court of competent jurisdiction and
the expiration of time to appeal or the denial of the last right of appeal) that
such indemnification may not be enforced in such case notwithstanding the fact
that this Section 4.1(f) provides for indemnification in such case; then, and in
such case, the party that would otherwise be required to indemnify under Section
4.1(f) will contribute to the aggregate losses, claims, damages or liabilities
to which the other parties may be subject (after contribution from others) in
such proportion as is appropriate to reflect the relative fault of the parties
in connection with the losses suffered, as well as any other relevant equitable
considerations.

               (g) The Company shall cooperate with the Investors to facilitate
the timely preparation and delivery of certificates representing the Shares to
be offered for resale pursuant to the Registration Statement and enable such
certificates to be in such denomination or amounts, as the case may be, as the
Investors may reasonably request and registered in such names as the Investors
may request after a Registration Statement which includes the Shares is ordered
effective by the SEC, that the Company deliver, and on such request, the Company
shall cause its legal counsel to deliver to the transfer agent for the Shares an
opinion of such counsel in appropriate form to ensure the transfer of such
shares without legend upon delivery by the Investors to the transfer agent of an
Investor certificate that the resale was made via proper delivery of the
Prospectus under the Registration Statement.
<PAGE>

          4.2 Deliverables Upon Effectiveness. When and if the SEC declares the
Registration Statement effective, the Company shall promptly deliver to each
Investor:

               (a) A certificate signed by the Chief Executive Officer or
President of the Company that the Registration Statement is effective and, to

has complied with the reporting requirements of SEC Rule 144, the Securities Act
and the Exchange Act, or that it qualifies as a registrant whose securities may
be resold pursuant to Form S-3 (at any time it so qualifies), (ii) a copy of the
most recent annual or quarterly report of the Company and such other reports and
documents so filed by the Company and (iii) such other information as may be
reasonably requested in availing such Investor of any rule or regulation of the
SEC which permits the selling of any such securities without registration or
pursuant to such form.

          4.4 Obligations of the Company. In connection with the registration
obligations of the Company pursuant to this Agreement, the Company shall, as
expeditiously as reasonably possible:

               (a) Furnish to the Holders such numbers of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the Securities Act, and such other documents as they may
reasonably request in order to facilitate the disposition of Common Stock owned

                                  July 31, 2001

To the Investors listed on
Schedule A to the Common
Stock PIPES Purchase Agreement dated July 25, 2001

Ladies and Gentlemen:

     We have acted as counsel for P-COM, Inc., a Delaware corporation (the
"Company"), in connection with the issuance and sale to you of 3,797,468 shares
of its common stock, par value $.0001 per share, pursuant to the Common Stock
PIPES Purchase Agreement dated July 25, 2001 (the "Stock Purchase Agreement")
among the Company and you. This opinion letter is being rendered to you pursuant
to Section 5.4 of the Stock Purchase Agreement in connection with the Closing of
the sale of the Shares. Capitalized terms not otherwise defined in this opinion
letter have the meanings given them in the Stock Purchase Agreement.

     In connection with the opinions expressed herein, we have made such
examination of matters of law and of fact as we considered appropriate or
advisable for purposes hereof. As to matters of fact material to the opinions
expressed herein, we have relied upon the representations and warranties as to
factual matters contained in and made by the Company pursuant to the Stock
Purchase Agreement and upon certificates and statements of government officials
and of officers of the Company. We have also examined originals or copies of
such corporate documents or records of the Company as we have considered
appropriate for the opinions expressed herein. We have assumed for the purposes
of this opinion letter the genuineness of all signatures, the legal capacity of
natural persons, the authenticity of the documents submitted to us as originals,
the conformity to the original documents of all documents submitted to us as
certified, facsimile or photostatic copies, and the authenticity of the
originals of such copies.

     In rendering this opinion letter we have also assumed: (A) that the Stock
Purchase Agreement has been duly and validly executed and delivered by you or on
your behalf, that you have the power to enter into and perform all your
obligations thereunder, and that the Stock Purchase Agreement constitutes a
valid, legal, binding and enforceable obligation upon you; (B) that the
representations and warranties made in the Stock Purchase Agreement by you are
true and correct; (C) that any wire transfers, drafts or checks tendered by you
will be honored; and (D) that you have filed any required State Franchise income
or similar tax returns and have paid any required State Franchise, income or
similar taxes.

     As used in this opinion letter, the expression "we are not aware" or the
phrase "to our knowledge", or any similar expression or phrase with respect to
our knowledge of matters of fact, means as to matters of fact that, based on the
actual knowledge of individual attorneys within the firm principally responsible
for handling current matters for the Company (and not including any constructive
or imputed notice of any information), and after an examination of documents
referred to herein and after inquiries of certain officers of the Company, no
facts have
<PAGE>

been disclosed to us that have caused us to conclude that the opinions expressed
are factually incorrect; but beyond that we have made no factual investigation
for the purposes of rendering this opinion letter. Specifically, but without
limitation, we have not searched the dockets of any courts and we have made no
inquiries of securities holders or employees of the Company, other than such
officers.

     This opinion letter relates solely to the laws of the State of California,
the General Corporation Law of the State of Delaware and the federal law of the
United States and we express no opinion with respect to the effect or
application of any other laws. Special rulings of authorities administering such
laws or opinions of other counsel have not been sought or obtained.

     Based upon our examination of and reliance upon the foregoing and subject
to the limitations, exceptions, qualifications and assumptions set forth below
and except as set forth in the Stock Purchase Agreement or the Disclosure
Schedule delivered in connection therewith, we are of the opinion that as of the
date hereof:

     1. The Company is a corporation duly incorporated, validly existing and in
good standing under the laws of the State of Delaware, and the Company has the
requisite corporate power and authority to own its properties and to conduct its
business as, to our knowledge, it is presently conducted. The Company is
qualified to do business as a foreign corporation in the state of California.

     2. The Company has the requisite corporate power and authority to execute,
deliver and perform the Stock Purchase Agreement, and to issue the Shares. The
Stock Purchase Agreement has been duly and validly authorized by the Company,
duly executed and delivered by an authorized officer of the Company and
constitutes a legal, valid and binding obligation of the Company, enforceable by
you against the Company in accordance with its terms.

     3. The Shares have been duly authorized and, upon purchase at the Closing
pursuant to the terms of the Stock Purchase Agreement, will be validly issued,
nonassessable and fully paid, and free of any liens created by the Company.

     4. The Company's execution and delivery of, and its performance and
compliance as of the date hereof with the terms of, the Stock Purchase Agreement
do not violate any provision of any federal, Delaware corporate or California
law, rule or regulation applicable to the Company or any provision of the
Company's Restated Certificate of Incorporation or Bylaws and do not conflict
with or constitute a default under the provisions of any judgment, writ, decree
or order specifically identified in the SEC Reports or the material provisions
of any of the material agreements specifically identified in the SEC Reports.

     5. Other than in connection with any securities laws, all consents,
approvals, permits, orders or authorizations of, and all qualifications by and
registrations with, any federal or Delaware corporate or California state
governmental authority on the part of the Company required in connection with
the execution and delivery of the Stock Purchase Agreement and consummation at
the Closing of the transactions contemplated by the Stock Purchase Agreement
<PAGE>

have been obtained, and are effective, and we are not aware of any proceedings,
or written threat of any proceedings, that question the validity thereof.

     6. Based in part upon the representations of you in the Stock Purchase
Agreement, the offer and sale of the Shares to you pursuant to the terms of the
Stock Purchase Agreement are exempt from the registration requirements of
Section 5 of the Securities Act of 1933, as amended, and from the qualification
requirements of the California Corporate Securities Law of 1968, as amended.

     Our opinions expressed above are specifically subject to the following
limitations, exceptions, qualifications and assumptions:

     (A) The legality, validity, binding nature and enforceability of the
Company's obligations under the Stock Purchase Agreement may be subject to or
limited by (1) bankruptcy, insolvency, reorganization, arrangement, moratorium,
fraudulent transfer and other similar laws affecting the rights of creditors
generally; (2) general principles of equity (whether relief is sought in a
proceeding at law or in equity), including, without limitation, concepts of
materiality, reasonableness, good faith and fair dealing, and the discretion of
any court of competent jurisdiction in awarding specific performance or
injunctive relief and other equitable remedies; and (3) without limiting the
generality of the foregoing, (a) principles requiring the consideration of the
impracticability or impossibility of performance of the Company's obligations at
the time of the attempted enforcement of such obligations, and (b) the effect of
California court decisions and statutes which indicate that provisions of the
Stock Purchase Agreement which permit you to take action or make determinations
may be subject to a requirement that such action be taken or such determinations
be made on a reasonable basis in good faith or that it be shown that such action
is reasonably necessary for your protection.

     (B) We express no opinion as to the Company's compliance or noncompliance
with applicable federal or state antifraud or antitrust statutes, laws, rules
and regulations or the Exon-Florio Amendment.

     (C) We express no opinion concerning the past, present or future fair
market value of any securities.

     (D) We express no opinion as to the enforceability under certain
circumstances of any provisions indemnifying a party against, or requiring
contributions toward, that party's liability for its own wrongful or negligent
acts, or where indemnification or contribution is contrary to public policy or
prohibited by law. In this regard, we advise you that in the opinion of the
Securities and Exchange Commission, indemnification of directors, officers and
controlling persons of an issuer against liabilities arising under the
Securities Act of 1933, as amended, is against public policy and is therefore
unenforceable.

     (E) We express no opinion as to the enforceability under certain
circumstances of any provisions prohibiting waivers of any terms of the Stock
Purchase Agreement other than in writing, or prohibiting oral modifications
thereof or modification by course of dealing. In addition, our opinions are
subject to the effect of judicial decisions which may permit the introduction of
extrinsic evidence to interpret the terms of written contracts.
<PAGE>

     (F) We express no opinion as to the effect of Section 1670.5 of the
California Civil Code or any other California law, federal law or equitable
principle which provides that a court may refuse to enforce, or may limit the
application of, a contract or any clause thereof which the court finds to have
been unconscionable at the time it was made or contrary to public policy.

     (G) We express no opinion as to the effect of Sections 1203 and 1102(3) of
the California Uniform Commercial Code or any other California law, federal law
or equitable principle, providing for an obligation of good faith in the
performance or enforcement of contracts and prohibiting disclaimer of such
obligation.

     (H) Our opinions in paragraphs 4 and 5 above are limited to laws and
regulations normally applicable to transactions of the type contemplated in the
Stock Purchase Agreement and do not extend to licenses, permits and approvals
necessary for the conduct of the Company's business. In addition and without
limiting the previous sentence, we express no opinion herein with respect to the
effect of any land use, safety, hazardous material, environmental or similar
law, or any local or regional law. Further, we express no opinion as to the
effect of or compliance with any state or federal laws or regulations applicable
to the transactions contemplated by the Stock Purchase Agreement because of the
nature of the business of any party thereto other than the Company. Also, we
express no opinion with respect to any patent, copyright, trademark or other
intellectual property matter, or as to the statutes, regulations, treaties or
common laws of any nation, state or jurisdiction with regard thereto.

     (I) In connection with our opinion in paragraph 4 relating to the material
agreements specifically identified in the SEC Reports, we have not reviewed, and
express no opinion on, (i) financial covenants or similar provisions requiring
financial calculations or determinations to ascertain whether there is any such
conflict or (ii) provisions relating to the occurrence of a "material adverse
event" or words of similar import. In addition, our opinions are subject to the
effect of judicial decisions which may permit the introduction of extrinsic
evidence to interpret the terms of written contracts. Moreover, to the extent
that any of the material agreements specifically identified in the SEC Reports
are governed by the laws of any jurisdiction other than the State of California
our opinion relating to those agreements is based solely upon the plain meaning
of their language without regard to interpretation or construction that might be
indicated by the laws governing those agreements.

     (J) We express no opinion as to your compliance with any Federal or state
law relating to your legal or regulatory status or the nature of your business.

     (K) We express no opinion as to the compliance of the Company, you or the
sale of the Common Stock to you with the provisions of the Small Business
Investment Act of 1958, as amended, or any of the regulations promulgated
thereunder.
<PAGE>

     (L) We express no opinion as to the effect of subsequent issuances of
securities of the Company, to the extent that further issuances which may be
integrated with the Closing may include purchasers that do not meet the
definition of "accredited investors" under Rule 501 of Regulation D and
equivalent definitions under state securities or "blue sky" laws.

     (M) We express no opinion as to Section 7.2 of the Stock Purchase Agreement
to the extent that it purports to exclude conflict of law principles under
California law.

     This opinion letter is rendered as of the date first written above solely
for your benefit in connection with the Stock Purchase Agreement and may not be
delivered to, quoted or relied upon by any person other than you, or for any
other purpose, without our prior written consent. Our opinion is expressly
limited to the matters set forth above and we render no opinion, whether by
implication or otherwise, as to any other matters relating to the Company or the
Shares. We assume no obligation to advise you of facts, circumstances, events or
developments which hereafter may be brought to our attention and which may

                               _____________, 2002

To the Investors listed on
Schedule A to the Common
Stock PIPES Purchase Agreement dated July 25, 2001

Ladies and Gentlemen:

     We have acted as counsel for P-COM, Inc., a Delaware corporation (the
"Company"), in connection with the issuance and sale to you of certain Shares of
its common stock, par value $.0001 per share, pursuant to the Common Stock PIPES
Purchase Agreement dated July 25, 2001 (the "Stock Purchase Agreement") among
the Company and you and in connection with the Company's registration with the
SEC of such Shares for resale by you. This opinion letter is being rendered to
you pursuant to Section 4.2(b) of the Stock Purchase Agreement in connection
with the SEC declaring effective the Registration Statement for your resale of
the Shares. Capitalized terms not otherwise defined in this opinion letter have
the meanings given them in the Stock Purchase Agreement.

     In our capacity as counsel to the Company, we have examined, among other
things, originals, or copies identified to our satisfaction as being true
copies, of the Registration Statement on Form S-3 (File No. 333-____________)
initially filed by the Company with the SEC on ____________, 2002, for the
purpose of registering the resale of the Shares under the Securities Act;
Amendment No. 1 to such Registration Statement filed with the SEC on
_____________, 2002; Amendment No. 2 to such Registration Statement filed with
the SEC on _____________, 2002; and oral advice on ______________, 2002, from an
SEC staff examiner, that the SEC had declared such Registration Statement, as so
amended, effective as of ______ p.m., Washington, D.C. time, on _____________,
2002.

     As used in this opinion letter, the phrase "to our knowledge" means as to
matters of fact that, based on the actual knowledge of individual attorneys
within the firm principally responsible for handling current matters for the
Company (and not including any constructive or imputed notice of any
information), no facts have been disclosed to us that have caused us to conclude
that the opinions expressed are factually incorrect; but our affirmative factual
investigation for the purpose of rendering this opinion letter has been limited
to obtaining (a) oral advice received on ___________, from an SEC staff
examiner, that the SEC had declared such Registration Statement, as amended,
effective at _____ p.m. Washington, D.C. time, on _________ , 2002 and (b) oral
advice received on ___________, 2002 from an SEC staff examiner that there is no
stop order suspending the effectiveness of the Registration Statement.

     Based upon our examination of and reliance upon the foregoing, we are of
the opinion that as of the date hereof:
<PAGE>

     1. The Registration Statement has become effective under the Securities Act
and, to our knowledge, no stop order suspending the effectiveness of the
Registration Statement has been issued and no proceedings for that purpose are
pending before or contemplated by the SEC.

     This opinion letter is rendered as of the date first written above solely
for your benefit in connection with the Stock Purchase Agreement and the
Registration Statement and may not be delivered to, quoted or relied upon by any
person other than you, or for any other purpose, without our prior written
consent. Our opinion is expressly limited to the matters set forth above and we
render no opinion, whether by implication or otherwise, as to any other matters
relating to the Company, the Stock Purchase Agreement, the Registration
Statement or the Shares. We assume no obligation to advise you of facts,
circumstances, events or developments which hereafter may be brought to our
attention and which may alter, affect or modify the opinions expressed herein.

                                    Very truly yours,

                                    BROBECK, PHLEGER & HARRISON LLP<PAGE>

     Affiliates and Associates of such Person, is the Beneficial Owner of less
     than fifteen percent (15%) of the outstanding shares of Common Stock become
     an Acquiring Person solely as a result of a reduction of the number of
     shares of outstanding Common Stock, including repurchases of outstanding
     shares of Common Stock by the Company, which reduction increases the
     percentage of outstanding shares of Common Stock Beneficially Owned (as
     such term is hereinafter defined) by such Person; provided, however, that
                                                       --------  -------
     any subsequent increase in the amount of Common Stock Beneficially Owned by
     such Person, together with all Affiliates and Associates of such Person,
     without the prior written approval of the Board shall cause such Person to

     date of initial acquisition of the Company's securities by such underwriter
     in connection with such offering);

               (iii)  no Person shall be deemed to be an Acquiring Person if:

     Person pursuant to the first sentence of this Section 1(a), (or such other
                                                   ------------

earlier of such dates being herein referred to as the "Distribution Date"), (x)

the Rights shall be evidenced by the certificates for Common Stock registered in
the names of the holders of the Common Stock (which certificates for Common
Stock shall be deemed also to be certificates for Rights) and not by separate
certificates and (y) the Rights (and the right to receive certificates therefor)
shall be transferable only in connection with the transfer of the underlying
shares of Common Stock. As soon as practicable after the Distribution Date, the
Company shall provide the Rights Agent with a list of holders of Common Stock
and the Rights Agent shall send, by first-class, insured, postage prepaid mail,
to each record holder of the Common Stock as of the Close of Business on the
Distribution Date, at the address of such holder shown on the records of the
Company, a certificate for Rights, in substantially the form of Exhibit B hereto

(the "Rights Certificates"), evidencing one Right for each share of Common Stock
      -------------------
so held (subject to adjustment as provided herein). As of and after the
Distribution Date, the Rights shall be evidenced solely by such Rights
Certificates.

     The Company shall promptly notify the Rights Agent in writing upon the
occurrence of the Distribution Date and, if such notification is given orally,
the Company shall confirm same in writing on or prior to the Business Day next
following. Until such notice is received by the Rights Agent, the Rights Agent
may presume conclusively for all purposes that the Distribution Date has not
occurred.

     Promptly following the Record Date, the Company shall send a copy of a
Summary of Rights, in substantially the form attached hereto as Exhibit C (the
                                                                ---------
"Summary of Rights"), by first-class, postage prepaid mail, to each record

the address of such holder shown on the records of the Company. With respect to
certificates for the Common Stock outstanding as of the Record Date, until the
Distribution Date (or earlier redemption, expiration or termination of the
Rights), the Rights shall be evidenced by such certificates for the Common Stock
and the registered holders of the Common Stock shall also be the registered
holders of the associated Rights. Until the Distribution Date (or earlier
redemption, expiration or termination of the Rights), the surrender for transfer
of any of the certificates for the Common Stock outstanding on the Record Date
shall also constitute the transfer of the Rights associated with the Common
Stock represented by such certificate.

          (b)  Certificates issued for Common Stock (including, without
limitation, certificates issued upon transfer or exchange of Common Stock) after
the Record Date, but prior to the earlier of the Distribution Date or the
Expiration Date (as such term is hereinafter defined), shall be deemed also to
be certificates for Rights, and shall have impressed, printed, stamped, written
or otherwise affixed onto them the following legend:

     This certificate also evidences and entitles the holder hereof to
     certain "Rights" as set forth in a Rights Agreement between
     Symmetricom, Inc. (the "Company") and Mellon Investor Services LLC
     (the "Rights Agent") dated as of August 9, 2001 (the "Rights
     Agreement"), the terms of which are hereby incorporated herein by
     reference and a copy of which is on file at the principal offices of
     the Company. Under certain circumstances, as set forth in the Rights
     Agreement, such Rights may be redeemed, may expire or may be
     evidenced by separate certificates and will no longer be evidenced
     by this certificate. The Company will mail to the holder of this
     certificate a copy of the Rights Agreement without charge after
     receipt of a written request therefor. Under certain circumstances,
     Rights "Beneficially Owned" by "Acquiring Persons" (as such terms
     are defined in the Rights Agreement) or certain related parties, as
     well as subsequent holders of such Rights, may become null and void.

     With respect to such certificates containing the foregoing legend, until
the Distribution Date (or earlier redemption, expiration or termination of the
Rights), the Rights associated with the Common Stock represented by such
certificates shall be evidenced by such certificates alone, and the surrender
for transfer of any of such certificates shall also constitute the transfer of
the Rights associated with the Common Stock represented by such certificate.

     4.   Form of Rights Certificates.
          ---------------------------

          (a)  The Rights Certificates (and the forms of election to purchase
shares and of assignment and certificates to be printed on the reverse thereof)
shall each be substantially in the form set forth in Exhibit B hereto and may
                                                     ---------
have such marks of identification or designation and such legends, summaries or
endorsements printed thereon as the Company may deem appropriate and as are not
inconsistent with the provisions of this Agreement, and do not affect the
rights, duties or responsibilities of the Rights Agent 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 or interdealer
quotation system on which the Rights may from time to time be listed or traded,
or to conform to usage.  Subject to the provisions of Section 11 and Section 23
                                                      ----------     ----------
hereof, the Rights Certificates, whenever distributed, shall be dated as of the
Record Date, and on their face shall entitle the holders thereof to purchase
such number of one one-thousandths of a share of Preferred Stock as shall be set
forth therein at the price per one one-thousandth of a share set forth therein
(the "Purchase Price"), such Purchase Price to be initially equal to the amount
      --------------
set forth in Section 7(b) below but the number of one one-thousandths of a share
             ------------
and the Purchase Price shall be subject to adjustment as provided herein.

          (b)  Any Rights Certificate issued pursuant to Section 3(a) hereof
                                                         ------------
that represents Rights Beneficially Owned by an Acquiring Person or any
Associate or Affiliate thereof, any Rights Certificate issued at any time upon
the transfer of any Rights to such an Acquiring Person or any Associate or
Affiliate thereof or to any nominee of such Acquiring Person, Associate or
Affiliate, and any Rights Certificate issued pursuant to Section 6, Section 11
                                                         ---------  ----------
or Section 23 hereof upon transfer, exchange, replacement or adjustment of any
   ----------
other Rights Certificate referred to in this sentence, shall contain the
following legend:

                                       6
<PAGE>

     The Rights represented by this Rights Certificate were issued to a
     Person who was an Acquiring Person or an Affiliate or an Associate
     of an Acquiring Person (as such terms are defined in the Rights
     Agreement). This Rights Certificate and the Rights represented
     hereby may become null and void under the circumstances specified in
     Section 7(e) of the Rights Agreement.

The provisions of Section 7(e) hereof shall be operative whether or not the
                  ------------
foregoing legend is contained on any such Rights Certificate.

     5.   Countersignature and Registration.
          ---------------------------------

          (a)  The Rights Certificates shall be executed on behalf of the
Company by its Chief Executive Officer, its President, its Chief Financial
Officer or any Vice President, either manually or by facsimile signature, and
shall have affixed thereto the Company's seal or a facsimile thereof which shall
be attested by the Secretary or an Assistant Secretary of the Company, either
manually or by facsimile signature. The Rights Certificates shall be
countersigned by the Rights Agent, either manually or by facsimile signature,
and shall not be valid for any purpose unless so countersigned. In case any
officer of the 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 Certificates 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 Agreement any such Person was not such an officer.

          (b)  Following the Distribution Date and receipt by the Rights Agent
of notice to that effect and any necessary information, the Rights Agent will
keep or cause to be kept, at its office designated for such purpose, books for
registration and transfer of the Rights Certificates 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.

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

          (a)  Subject to the provisions of Sections 7(e), 7(f) and 15 hereof,
                                            --------------------------
at any time after the Close of Business on the Distribution Date, and at or
prior to the Close of Business on the Expiration Date, any Rights Certificate or
Certificates 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-thousandths of a share of Preferred Stock (or,
after the occurrence of a Triggering Event, shares of Common Stock or other
securities and property, as the case may be) as the Rights Certificate or Rights
Certificates surrendered then entitled such holder (or former holder in the case
of a transfer) to purchase. Any registered holder desiring to transfer, split
up, combine or exchange any Rights Certificate shall make such request in
writing delivered to the Rights Agent, and shall surrender the Rights
Certificate or Rights Certificates to

                                       7
<PAGE>

be transferred, split up, combined or exchanged at the office of the Rights
Agent designated for such purpose. Subject to receipt by the Company and the
Rights Agent of evidence reasonably satisfactory to them (as the Company may
reasonably request) of the identity of the Beneficial Owner (or former
Beneficial Owner) of the Rights Certificate or the Affiliates or Associates
thereof, the Rights Agent shall (subject to Section 7(e) hereof) thereupon
                                            ------------
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 charge that may be
imposed in connection with any transfer, split up, combination or exchange of
Rights Certificates. The Rights Agent shall have no duty or obligation under
this Section 6 unless and until it is satisfied that all applicable taxes and
     ---------
charges have been paid in full.

          (b)  Subject to the provisions of Sections 7(e), 7(f) and 15 hereof,
                                            --------------------------
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 such additional evidence of the identity of the Beneficial Owner
(or former Beneficial Owner) or Affiliates or Associates thereof as the Company
or the Rights Agent shall reasonably request, and, in case of loss, theft or
destruction, of indemnity or security satisfactory to them, and 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 shall execute and deliver a new Rights
Certificate of like tenor to the Rights Agent for countersignature and delivery
to the registered owner in lieu of the Rights Certificate so lost, stolen,
destroyed or mutilated.

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

          (a)  Subject to the provisions of Sections 7(e) and 7(f) hereof, the
                                            ----------------------
registered holder of any Rights Certificate may exercise the Rights evidenced
thereby (except as otherwise provided herein) in whole or in part at any time
after the Distribution Date upon presentation of the Rights Certificate, with
the appropriate form of election to purchase on the reverse side thereof duly
executed, to the Rights Agent at the office of the Rights Agent set forth in
Section 26 hereof, together with payment of the Purchase Price for each one one-
----------

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 August 9, 2011 (the "Final Expiration

----                                                                  ----------
hereof, (iii) the consummation of a transaction contemplated by Section 13(d)
                                                                -------------
hereof or (iv) the time at which the Rights are exchanged as provided in Section
                                                                         -------
24(c) hereof (such earliest time being herein referred to as the "Expiration

Date").  Notwithstanding any other provision of this Agreement, any Person who
----
prior to the Distribution Date becomes a record holder of shares of Common Stock
may exercise all of the rights of a registered holder of a Rights Certificate
with respect to the Rights associated with such shares of Common Stock in
accordance with and subject to the provisions of this Agreement, including the
provisions of Section 7(e) hereof, as of the date such Person becomes a record
              ------------
holder of shares of Common Stock.

          (b)  The Purchase Price for each one one-thousandth of a share of
Preferred Stock pursuant to the exercise of a Right shall initially be Seventy-
                                                                       -------
Two and 82/100ths  Dollars ($72.82), 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) of this Section 7 below.
                -------------         ---------

          (c)  Upon receipt of a Rights Certificate representing exercisable
Rights, with the appropriate form of election to purchase duly executed,
accompanied by payment of the Purchase Price for the fractional interests in
shares of Preferred Stock (or other securities or property) to be purchased and
an amount equal to any applicable tax or charge in cash, or by certified check
or bank draft payable to the order of the Company, the Rights Agent shall,
subject to Section 21(k) hereof, thereupon promptly (i)(A) requisition from any
           -------------
transfer agent of the shares of Preferred Stock (or make available, if the
Rights Agent is the transfer agent) certificates for the number of one one-
thousandths of a share of Preferred Stock to be purchased, and the Company
hereby irrevocably authorizes its transfer agent to comply with all such
requests, or (B) if the Company, in its sole discretion, shall have elected to
deposit the fractional interests in shares of Preferred Stock issuable upon
exercise of the Rights hereunder into a depositary, requisition from the
depositary agent depositary receipts representing such number of one one-
thousandths of a share of Preferred Stock as are to be purchased (in which case
certificates for the one one-thousandths of a share of Preferred Stock
represented by such receipts shall be deposited by the transfer agent with the
depositary agent) and the Company shall direct the depositary agent to comply
with such request, (ii) when appropriate, requisition from the Company the
amount of cash, if any, to be paid in lieu of issuance of fractional shares in
accordance with Section 15, (iii) promptly 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
promptly deliver such cash to or upon the order of the registered holder of such
Rights Certificate.  In the event that the Company is obligated to issue other
securities of the Company, and/or distribute other property pursuant to Section
                                                                        -------
11(a), the Company shall make all arrangements necessary so that such other
-----
securities and/or property are available for distribution by the Rights Agent,
if and when appropriate. In addition, in the case of an exercise of the Rights
by a holder pursuant to Section 11(a)(ii), the Rights Agent shall return such
                        -----------------
Rights Certificate to the registered holder thereof after imprinting, stamping
or otherwise indicating thereon that the rights represented by such Rights
Certificate no longer include the rights provided by Section 11(a)(ii) hereof;
                                                     -----------------
provided, however, that if less than all the Rights represented by such Rights
--------  -------
Certificate were so exercised, the Rights Agent shall indicate on the Rights
Certificate the number of Rights represented thereby which continue to include
the rights provided by Section 11(a)(ii).
                       -----------------

          (d)  In case the registered holder of any Rights Certificate shall
exercise (except pursuant to Section 11(a)(ii)) 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 and delivered
to the registered holder of such Rights Certificate or to such registered
holder's duly authorized assigns, subject to the provisions of Section 6 and
                                                               ---------
Section 15 hereof.
----------

          (e)  Notwithstanding anything in this Agreement to the contrary, if
there occurs any Triggering Event, then any Rights that are or were on or after
the Distribution Date Beneficially Owned by an Acquiring Person or any Associate
or Affiliate of an Acquiring Person shall become null and void, without any
further action, and any holder of such Rights shall

                                       9
<PAGE>

thereafter have no rights whatsoever with respect to such Rights, whether under
any provision of this Agreement or otherwise. Without limiting the foregoing
sentence, Rights held by the following Persons shall be null and void without
any further action: (i) any direct or indirect transferee of any Rights that are
or were on or after the Distribution Date Beneficially Owned by an Acquiring
Person or any Associate or Affiliate of an Acquiring Person; (ii) any direct or
indirect transferee of any Rights that were on or before the Distribution Date
Beneficially Owned by an Acquiring Person or any Associate or Affiliate of an
Acquiring Person if the transferee received such Rights, directly or indirectly,
(A) from an Acquiring Person or any Associate or Affiliate of an Acquiring
Person (x) as a result of a distribution by such Acquiring Person or any
Associate or Affiliate of an Acquiring Person to holders of its equity
securities or similar interests (including, without limitation, partnership
interests) or (y) pursuant to any continuing agreement, arrangement or
understanding with respect to the Rights or (B) in a transfer (or series of
transfers) which the Board determines is part of a plan, agreement, arrangement
or understanding which has the purpose or effect of avoiding the provisions of
this Section 7(e); and (iii) subsequent transferees of Persons referred to in
     ------------
the foregoing clauses (i) and (ii) as well as this clause (iii). The Company
shall notify the Rights Agent when this Section 7(e) applies and shall use all
                                        ------------
reasonable efforts to ensure that the provisions of this Section 7(e) are
                                                         ------------
complied with, but neither the Company nor the Rights Agent shall have any
liability to any holder of Rights or any Rights Certificate or to any other
Person as a result of the Company's failure to make any determination with
respect to an Acquiring Person or its Affiliates, Associates or transferees
hereunder.

          (f)  Notwithstanding anything in this Agreement to the contrary,
neither the Rights Agent nor the 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 the Certificate contained in the
                              ---------
appropriate form of Election to Purchase set forth on the reverse side of the
Rights Certificate surrendered for such exercise shall have been properly
completed and duly executed by the registered holder thereof and the Company
shall have been provided with such additional evidence of the identity of the
Beneficial Owner (or former Beneficial Owner) or Affiliates or Associates
thereof as the Company or the Rights Agent shall reasonably request.

     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 any of its
agents, be delivered to the Rights Agent for cancellation or in canceled form,
or, if surrendered to the Rights Agent, shall be canceled by it, and no Rights
Certificates shall be issued in lieu thereof except as expressly permitted by
any of the provisions of this 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
canceled Rights Certificates to the Company, or shall, at the written request of
the Company, destroy such canceled Rights Certificates, and in such case shall
deliver a certificate of destruction thereof to the Company.

     9.   Reservation and Availability of Preferred Stock.
          -----------------------------------------------

                                       10
<PAGE>

          (a)  The Company covenants and agrees that it shall cause to be
reserved and kept available out of its authorized and unissued shares of
Preferred Stock, or any authorized and issued shares of Preferred Stock (and,
following the occurrence of a Triggering Event, shares of Common Stock and other
securities) held in its treasury, the number of shares of Preferred Stock (and,
following the occurrence of a Triggering Event, shares of Common Stock and other
securities) that will be sufficient (in accordance with the provisions of this
Agreement, including Section 11(a)(iii) hereof) to permit the exercise in full
                     ------------------
of all outstanding Rights.

          (b)  So long as the shares of Preferred Stock (and, following the
occurrence of a Triggering Event, shares of Common Stock and other securities)
issuable upon the exercise of the Rights may be listed on any national
securities exchange or quoted on any national quotation system, the Company
shall use its best efforts to cause, from and after such time as the Rights
become exercisable, all shares (or other securities) reserved for such issuance
to be listed on such exchange or quoted on such system upon official notice of
issuance upon such exercise.

          (c)  If then required by applicable law, the Company shall use its
best efforts to (i) file, as soon as practicable following the earliest date
after the occurrence of a Triggering Event as to which the consideration to be
delivered by the Company upon exercise of the Rights has been determined
pursuant to this Agreement, or as soon as is required by law following the
Distribution Date, as the case may be, a registration statement under the
Securities Act of 1933, as amended (the "Act"), with respect to the securities
                                         ---
purchasable upon exercise of the Rights on an appropriate form, (ii) cause such
registration statement to become effective as soon as practicable after such
filing and (iii) cause such registration statement to remain effective (with a
prospectus at all times meeting the requirements of the Act) until the earlier
of (A) the date as of which the Rights are no longer exercisable for such
securities, (B) the Expiration Date or (C) the date the Company receives an
opinion of counsel to the effect that the maintenance of such registration
statement in effect is no longer necessary. If then required by applicable law,
the Company will also take such action as may be appropriate under the
securities or "blue sky" laws of the various states. 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 this Section 9(c), the exercisability of the Rights in
                            ------------
order to prepare and file such registration statement or to comply with such
blue sky laws. Upon any such suspension, the Company shall promptly notify the
Rights Agent thereof and issue a public announcement stating that the
exercisability of the Rights has been temporarily suspended. Notwithstanding any
provision of this Agreement to the contrary, the Rights shall not be exercisable
in any jurisdiction unless the requisite qualification in such jurisdiction
shall have been obtained.

          (d)  The Company covenants and agrees that it shall take all such
action as may be necessary to ensure that all one one-thousandths of a share of
Preferred Stock and/or other securities delivered upon exercise of Rights shall,
at the time of delivery of the certificates for such shares or other securities
(subject to payment of the Purchase Price), be duly and validly authorized and
issued and fully paid and nonassessable shares or securities.

          (e)  The Company further covenants and agrees that it shall pay when
due and payable any and all taxes and charges which may be payable in respect of
the issuance or delivery of the Rights Certificates or of any certificates for
one one-thousandths of a share of Preferred Stock and/or other securities upon
the exercise of Rights. The Company shall not,

                                       11
<PAGE>

however, be required to (i) pay any tax or charge which may be payable in
respect of any transfer or delivery of Rights Certificates to a Person other
than, or in respect of the issuance or delivery of the shares of Preferred Stock
and/or other securities in a name other than that of, the registered holder of
the Rights Certificates evidencing Rights surrendered for exercise or (ii) issue
or deliver any certificates for shares of Preferred Stock and/or other
securities in a name other than that of the registered holder upon the exercise
of any Rights until such tax or charge shall have been paid (any such tax or
charge being payable by the holder of such Rights Certificate at the time of
surrender) or until it has been established to the Company's or Rights Agent's
satisfaction that no such tax or charge is due.

     10.  Preferred Stock Record Date. Each Person in whose name any certificate
          ---------------------------
for one one-thousandths of a share of Preferred Stock (or other securities) is
issued upon the exercise of Rights shall for all purposes be deemed to have
become the holder of record of the fractional shares of Preferred Stock (or
other securities) represented thereby on, and such certificate shall be dated,
the date upon which the Rights Certificate evidencing such Rights was duly
presented and payment of the Purchase Price (and any applicable taxes or
charges) was made; provided, however, that if the date of such presentation and
                   --------  -------
payment is a date upon which the Preferred Stock (or other securities) 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 Stock (or other securities)
transfer books of the Company are open. Prior to the exercise of the Rights
evidenced thereby, the holder of a Rights Certificate, as such, shall not be
entitled to any rights of a shareholder of the Company with respect to shares
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.

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

          (a)  (i)  In the event the Company shall at any time after the date of
this Agreement (A) declare a dividend on the Preferred Stock payable in shares
of Preferred Stock, (B) subdivide the outstanding Preferred Stock, (C) combine
the outstanding Preferred Stock into a smaller number of shares or (D) issue any
shares of its capital stock in a reclassification of the Preferred Stock
(including any such reclassification in connection with a consolidation or
merger in which the Company is the continuing or surviving corporation), except
as otherwise provided in this Section 11(a) and in Section 7(e) hereof, 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 and other securities which, if such Right had been exercised
immediately prior to such date and at a time when the Preferred Stock transfer
books of the Company were open, such holder would have owned upon such exercise
and been entitled to receive by virtue of such dividend, subdivision,
combination or reclassification.  If an event occurs which would require an
adjustment under both this Section 11(a)(i) and Section 11(a)(ii) hereof the
                           ----------------     -----------------
adjustment provided for in this Section 11(a)(i) shall be
                                ----------------

                                       12
<PAGE>

in addition to, and shall be made prior to, any adjustment required pursuant to
Section 11(a)(ii) hereof.
-----------------

               (ii)   Subject to Section 24(c) hereof, in the event any Person,
                                 -------------
alone or together with its Affiliates and Associates, shall become an Acquiring
Person other than pursuant to a Permitted Offer (such an event being a "Section
                                                                        -------
11 Event"), then, promptly following the first occurrence of such a Section 11
--------
Event, proper provision shall be made so that each holder of a Right, except as
provided in Section 7(e) hereof, shall, for a period of sixty (60) days after
            ------------
the later of the occurrence of any such Section 11 Event and the effective date
of an appropriate registration statement pursuant to Section 9 hereof, have a
                                                     ---------
right to receive, upon exercise thereof at the then current Purchase Price in
accordance with the terms of this Agreement, in lieu of fractional interests in
shares of Preferred Stock, such number of shares of Common Stock of the Company
as shall equal the result obtained by (x) multiplying the then current Purchase
Price by the number of one one-thousandths of a share of Preferred Stock for
which a Right was exercisable immediately prior to the Section 11 Event at issue
and (y) dividing that product by fifty percent (50%) of the current market price
per one share of Common Stock (determined pursuant to Section 11(d) hereof) on
                                                      -------------
the date of the occurrence of the Section 11 Event at issue (such number of
shares being referred to as the "number of Adjustment Shares"); provided,
                                 ---------------------------    --------
however, that if the transaction that would otherwise give rise to the foregoing
-------
adjustment is also subject to the provisions of Section 13 hereof, then only the
                                                ----------
provisions of Section 13 hereof shall apply and no adjustment shall be made
              ----------
pursuant to this Section 11(a)(ii); and provided, further, that such sixty (60)
                 -----------------      --------  -------
day period shall not be deemed to run during any period in which the exercise of
the Rights or the fulfillment by the Company or the Rights Agent of its or their
obligations under this Agreement shall be enjoined or otherwise prohibited in
full or in part by any court or other governmental agency or body.

               (iii)  In lieu of issuing shares of Common Stock in accordance
with Section 11(a)(ii) hereof, the Company may, if a majority of the Board then
     ----------------
in office determines that such action is necessary or appropriate and not
contrary to the interests of holders of Rights, elect to (and, in the event that
the Board has not exercised the exchange right contained in Section 24(c) hereof
                                                            -------------
and there are not sufficient treasury shares and authorized but unissued shares
of Common Stock to permit the exercise in full of the Rights in accordance with
Section 11(a)(ii) hereof, 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, shares of
Common Stock, other securities (whether equity or debt securities of the
Company, any Subsidiary of the Company, or otherwise) or any combination thereof
having an aggregate value equal to the value of the shares of Common Stock which
otherwise would have been issuable pursuant to Section 11(a)(ii) hereof, which
                                               -----------------
aggregate value shall be determined by a nationally recognized investment
banking firm selected by a majority of the Board.  For purposes of the preceding
sentence, the value of the Common Stock shall be determined pursuant to Section
                                                                        -------
11(d) hereof and the value of any fractional interests in preferred stock or
-----
preference stock which a majority of the Board determines to be a "common stock
                                                                   ------------
equivalent" shall be deemed to have the same value as the Common Stock. Any such
----------
election by the Board must be made and publicly announced within sixty (60) days
following the date on which the Section 11 Event at issue shall have occurred
with prompt notice thereof to the Rights Agent. Following the occurrence of such
Section 11 Event, a majority of the Board then in office may suspend the
exercisability of the Rights for a period of up to sixty (60) days following

                                       13
<PAGE>

the date on which such Section 11 Event shall have occurred to the extent that
such Directors have not determined whether to exercise their rights of election
under this Section 11(a)(iii). If the Board shall determine in good faith that
           ------------------
it is likely that sufficient additional shares of Common Stock or common stock
equivalents could be authorized for issuance upon exercise in full of the
Rights, the sixty (60) day period set forth above may be extended to the extent
necessary, but not more than ninety (90) days following the occurrence of the
Section 11 Event at issue, in order that the Company may seek shareholder
approval for the authorization of such additional shares. 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 with prompt notice
thereof to the Rights Agent.

          (b)  If the Company shall fix a record date for the issuance of
rights, options or warrants to all holders of any interests in Preferred Stock
entitling them (for a period expiring within forty-five (45) calendar days after
such record date) to subscribe for or purchase any interests in Preferred Stock
(or securities having the same or more favorable rights, privileges and
preferences as the Preferred Stock ("equivalent preferred stock")) or securities
                                     --------------------------
convertible into Preferred Stock or equivalent preferred stock at a price per
share of Preferred Stock or per share of equivalent preferred stock (or having a
conversion price per share, if a security convertible into Preferred Stock or
equivalent preferred stock) less than the current market price (as defined in
Section 11(d)) per share of Preferred Stock 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 shares of Preferred
Stock outstanding on such record date, plus the number of shares of Preferred
Stock which the aggregate offering price of the total number of shares of
Preferred Stock and/or equivalent preferred stock to be offered (and/or the
aggregate initial conversion price of the convertible securities so to be
offered) would purchase at such current market price and the denominator of
which shall be the number of shares of Preferred Stock outstanding on such
record date, plus the number of additional shares of Preferred Stock and/or
equivalent preferred stock to be offered for subscription or purchase (or into
which the convertible securities so to be offered are initially convertible). In
case such subscription price may be paid in a consideration part or all of which
shall be in a form other than cash, the value of such consideration shall be as
determined reasonably and with good faith to the holders of Rights by the Board,
whose determination shall be described in a statement filed with the Rights
Agent and shall be binding on the Rights Agent and conclusive for all purposes.
Shares of Preferred Stock 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)  If the Company shall fix a record date for the making of a
distribution to all holders of interests in Preferred Stock (including any such
distribution made in connection with a consolidation or merger in which the
Company is the continuing corporation) of evidences of indebtedness, cash (other
than a regular quarterly cash dividend out of the earnings or retained earnings
of the Company), assets (other than a dividend payable in Preferred Stock, but
including any dividend payable in stock other than Preferred Stock) or
subscription rights, options or warrants (excluding those referred to in Section
                                                                         -------
11(b) hereof), the Purchase Price to be in effect
-----

                                       14
<PAGE>

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 market price (as defined in Section 11(d)
                                                            -------------
hereof) per share of Preferred Stock on such record date, less the fair market
value (as determined reasonably and with good faith to the holders of Rights by
the Board, whose determination shall be described in a statement filed with the
Rights Agent and shall be binding on the Rights Agent and conclusive for all
purposes) of the portion of the cash, assets or evidences of indebtedness so to
be distributed or of such subscription rights, options or warrants distributable
in respect of one share of Preferred Stock and the denominator of which shall be
the then current market price (as defined in Section 11(d) hereof) per share of
                                             -------------
the Preferred Stock. 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
be in effect if such record date had not been fixed.

          (d)  (i)  For the purpose of any computation hereunder, other than as
provided in Section 11(a)(iii), the "current market price" per share of Common
         ---------------------       --------------------
Stock on any date shall be deemed to be the average of the daily closing prices
per share of such Common Stock for the thirty (30) consecutive Trading Days (as
such term is hereinafter defined) immediately prior to such date; provided,
                                                                  --------
however, that in the event that the current per share market price of the Common
-------
Stock is determined in whole or in part during a period following the
announcement by the issuer of such Common Stock of (A) a dividend or
distribution on such Common Stock payable in shares of such Common Stock or
securities convertible into shares of such Common Stock or (B) any subdivision,
combination or reclassification of such Common Stock, and prior to the
expiration of thirty (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 market price"
                                                       --------------------
shall be properly adjusted to take into account ex-dividend trading. 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 or admitted to
trading on the New York Stock Exchange or, if the shares of Common Stock are not
listed or admitted to trading on the New York Stock Exchange, as reported in the
principal consolidated transaction reporting system with respect to securities
listed on the principal national securities exchange on which the shares of
Common Stock are listed or admitted to trading or, if the shares of Common Stock
are not listed or admitted to trading on any national securities exchange but
are listed or quoted on The Nasdaq Stock Market, the last reported sale price,
or, in case no such sale takes place on such day, the average of the closing bid
and asked prices as reported by Nasdaq, or, if the shares of Common Stock are
not listed or quoted on The Nasdaq Stock Market, the last quoted price or, if
not so quoted, the average of the high bid and low asked prices in the over-the-
counter market, as reported by the OTC Bulletin Board or such other system then
in use, or, if on any such date the shares of Common Stock 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 Common Stock selected by
the Board. If on any such date no market maker is making a market in the Common
Stock, the fair value of such shares on such date as determined reasonably and
with good faith by the Board shall be used and shall be binding on the Rights
Agent and conclusive for all purposes. The term "Trading Day" shall mean a day
                                                 -----------
on which the principal national securities exchange or The Nasdaq Stock Market,
as the case may be, on which the shares of

                                       15
<PAGE>

Common Stock are principally listed or admitted to trading or quoted is open for
the transaction of business or, if the shares of Common Stock are not listed or
admitted to trading or quoted on any national securities exchange or The Nasdaq
Stock Market, a Business Day. If the Common Stock is not publicly held or not so
listed or traded, "current market price" per share shall mean the fair value per
                   --------------------
share determined reasonably and with good faith to the holders of Rights by the
Board, whose determination shall be described in a statement filed with the
Rights Agent and shall be binding on the Rights Agent and conclusive for all
purposes.

               (ii)   For the purpose of any computation hereunder, the "current
                                                                         -------
market price" per share (or one one-thousandth of a share) of Preferred Stock
------------
shall be determined in the same manner as set forth above for the Common Stock
in Section 11(d)(i) (other than the last sentence thereof). If the current
   ----------------
market price per share (or one one-thousandth of a share) of Preferred Stock
cannot be determined in the manner provided above or if the Preferred Stock is
not publicly held or listed or traded in a manner described in Section 11(d)(i),
                                                               ----------------
the "current market price" per share of Preferred Stock shall be conclusively
     --------------------
deemed to be an amount equal to 1,000 (as such number may be appropriately
adjusted for such events as stock splits, stock dividends and recapitalization
with respect to the Common Stock occurring after the date of this Agreement)
multiplied by the current market price per share of the Common Stock and the
"current market price" per one one-thousandth of a share of Preferred Stock
 --------------------
shall be equal to the current market price per share of the Common Stock (as
appropriately adjusted). If neither the Common Stock nor the Preferred Stock is
publicly held or so listed or traded, "current market price" per share shall
                                       --------------------
mean the fair value per share as determined in good faith by the Board, whose
determination shall be described in a statement filed with the Rights Agent and
shall be conclusive for all purposes.

          (e)  Anything herein to the contrary notwithstanding, no adjustment in
the Purchase Price shall be required unless such adjustment would require an
increase or decrease of at least one percent (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 thousandth of a share of Common Stock or
other share or one-millionth of a share of Preferred Stock, 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
                 ----------
(3) years from the date of the transaction which mandates such adjustment or
(ii) the Expiration Date.

          (f)  If as a result of any provision of this Section 11, the holder of
                                                       ----------
any Right shall become entitled to receive any shares of capital stock of the
Company other than Preferred Stock, 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 shares (and the related Purchase Price) contained
in this Section 11, and the provisions of Sections 7, 9, 10, 13 and 15 hereof
        ----------                        ---------------------     --
with respect to the Preferred Stock 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-thousandths of a
share of Preferred Stock purchasable

                                       16
<PAGE>

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) hereof, upon each adjustment of the Purchase Price as a result
   -------------
of the calculations made in Section 11(b) and (c) hereof, 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-
thousandths of a share of Preferred Stock (calculated to the nearest one-
millionth) obtained by (i) multiplying (x) the number of one one-thousandths of
a share of Preferred Stock 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-thousandths of a share of Preferred Stock
purchasable upon the exercise of a Right.  Each of the Rights outstanding after
the adjustment in the number of Rights shall be exercisable for the number of
one one-thousandths of a share of Preferred Stock for which a Right was
exercisable immediately prior to such adjustment.  Each Right held of record
prior to such adjustment of the number of Rights shall become that number of
Rights (calculated to the nearest one millionth) 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 and promptly notify the
Rights Agent 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 ten (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 15 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 may bear, at the option
of the Company, the adjusted Purchase Price) 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-thousandths of a share of Preferred Stock issuable upon
the exercise of the Rights, the Rights Certificates theretofore and thereafter
issued may continue to express the Purchase Price per one one-thousandths of a
share and the number of one one-thousandths of a share which were expressed in
the initial Rights Certificates issued hereunder.

                                       17
<PAGE>

          (k)  Before taking any action that would cause an adjustment reducing
the Purchase Price below the then par value, if any, of the number of one one-
thousandths of a share of Preferred Stock or shares of Common Stock or other
securities issuable upon exercise of the Rights (aggregating, for this purpose,
an appropriate amount of the Purchase Price for fractional shares to compare
such aggregated amount to the par value for a whole share), the Company shall
take any corporate action which may, in the opinion of its counsel, be necessary
in order that the Company may validly and legally issue fully paid and
nonassessable one one-thousandths of a share of Preferred Stock or shares of
Common Stock or other securities at such adjusted Purchase Price. If upon any
exercise of the Rights, a holder is to receive a combination of Common Stock and
common stock equivalents, or Preferred Stock and preferred stock equivalents, a
portion of the consideration paid upon such exercise, equal to at least the then
par value, if any, of a share of Common Stock or Preferred Stock of the Company,
as the case may be, shall be allocated as the payment for each share of Common
Stock or Preferred Stock of the Company, as the case may be, so received.

          (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 (and shall promptly notify the
Rights Agent of any such election) until the occurrence of such event the
issuing to the holder of any Right exercised after such record date the shares
of Preferred Stock and other capital stock or securities of the Company, if any,
issuable upon such exercise over and above the shares of Preferred Stock 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 to the contrary in this Section 11 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 Stock, issuance
wholly for cash of any shares of Preferred Stock at less than the current market
price, issuance wholly for cash of shares of Preferred Stock or securities which
by their terms are convertible into or exchangeable for shares of Preferred
Stock, stock dividends or issuance of rights, options or warrants referred to
hereinabove in this Section 11, hereafter made by the Company to holders of
                    ----------
Preferred Stock shall not be taxable to such shareholders.

          (n)  Anything in this Agreement to the contrary notwithstanding, in
the event that the Company shall at any time after the date of this Agreement
and prior to the Distribution Date (i) declare a dividend on the outstanding
shares of Common Stock payable in shares of Common Stock, (ii) subdivide the
outstanding Common Stock, (iii) combine the outstanding Common Stock into a
smaller number of shares, or (iv) issue any shares of its capital stock in a
reclassification of the outstanding Common Stock, the number of Rights
associated with each share of Common Stock then outstanding, or issued or
delivered thereafter but prior to the Distribution Date, shall be
proportionately adjusted so that the number of Rights thereafter associated with
each share of Common Stock following any such event shall equal the result
obtained by multiplying the number of Rights associated with each share of
Common Stock immediately prior to such event by a fraction the numerator of
which shall be the total number of

                                       18
<PAGE>

shares of Common Stock outstanding immediately prior to the occurrence of the
event and the denominator of which shall be the total number of shares of Common
Stock outstanding immediately following the occurrence of such event.

          (o)  The exercise of Rights under Section 11(a)(ii) hereof shall only
                                            -----------------
result in the loss of rights under Section 11(a)(ii) hereof to the extent so
                                   -----------------
exercised and shall not otherwise affect the rights represented by the Rights
under this Agreement, including the rights represented by Section 13 hereof.
                                                          ----------

     12.  Certificate of Adjusted Purchase Price or Number of Shares.  Whenever
          ----------------------------------------------------------
an adjustment or any event affecting the Rights or their exercisability
(including without limitation an event which causes Rights to become null and
void) occurs as provided in Sections 11 or 13 hereof, the Company shall (a)
                            ----------     --
promptly prepare a certificate setting forth such adjustment or describing such
event and a brief, reasonably detailed statement of the facts, computations and
methodology accounting for such adjustment, (b) promptly file with the Rights
Agent and with each transfer agent for the Preferred Stock and the Common Stock
a copy of such certificate and (c) mail a brief summary thereof to each holder
of a Rights Certificate in accordance with Section 26 hereof. The Rights Agent
                                           ----------
shall be fully protected in relying on any such certificate and on any
adjustment therein contained and shall have no duty with respect to and shall
not be deemed to have knowledge of any adjustment or event unless and until it
shall have received such certificate. Notwithstanding the foregoing provisions
of this Section 12, the failure of the Company to make such certification or
        ----------
give such notice shall not affect the validity, or the force or effect, of the
requirement for such adjustment or event.

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

          (a)  In the event that, following the Stock Acquisition Date, directly
or indirectly, (x) the Company shall consolidate with, or merge with and into,
any other Person, (y) 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 (other than, in the case of any transaction described
in (x) or (y), a merger or consolidation which would result in all of the Voting
Power represented by the securities of the Company outstanding immediately prior
thereto continuing to represent (either by remaining outstanding or by being
converted into securities of the surviving entity) all of the Voting Power
represented by the securities of the Company or such surviving entity
outstanding immediately after such merger or consolidation and the holders of
such securities not having changed as a result of such merger or consolidation),
or (z) 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 more than fifty percent (50%)
of the assets or earning power of the Company and its Subsidiaries (taken as a
whole) to any other Person (any of the events described in the foregoing clauses
(x), (y) or (z) being herein referred to as a "Section 13 Event"), then, and in
                                               ----------------
each such case, proper provision shall be made so that (i) each holder of a
Right (other than as provided in Section 7(e) hereof) shall have the right to
                                 ------------
receive, upon the exercise thereof at the then current Purchase Price in
accordance with the terms of this Agreement, such number of shares of freely
tradable Common Stock of the Principal Party (as hereinafter defined), free and
clear of liens, rights of call or first refusal, encumbrances or other adverse
claims, as shall be equal to the result obtained by (x) multiplying the then
current Purchase Price by the number of

                                       19
<PAGE>

one one-thousandths of a share of Preferred Stock for which a Right is then
exercisable (without taking into account any adjustment previously made pursuant
to Section 11(a)(ii) hereof) and (y) dividing that product by fifty percent
   -----------------
(50%) of the current market price per share of the Common Stock of such
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, it being specifically
intended that the provisions of Section 11 hereof shall apply 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 shares of its Common Stock
in accordance with Section 9 hereof) in connection with such consummation as may
                   ---------
be necessary to ensure that the provisions hereof shall thereafter be
applicable, as nearly as reasonably may be, in relation to its shares of Common
Stock thereafter deliverable upon the exercise of the Rights.

          (b)  "Principal Party" shall mean:
                ---------------

               (i)   in the case of any transaction described in clauses (x) or
     (y) of the first sentence of this Section 13, the Person that is the issuer
                                       ----------
     of any securities into which shares of Common Stock of the Company are
     converted in such merger or consolidation, and if no securities are so
     issued, the Person that is the other party to the merger or consolidation
     (including, if applicable, the Company, if it is the surviving
     corporation); and

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

     provided, however, that in any such case, (A) if the Common Stock of such
     --------  -------
     Person is not at such time and has not been continuously over the preceding
     twelve (12) month period registered under Section 12 of the Exchange Act,
     and such Person is a direct or indirect Subsidiary or Affiliate of another
     Person the Common Stock of which is and has been so registered, "Principal
                                                                      ---------
     Party" shall refer to such other Person; (B) in case such Person is a
     -----
     Subsidiary, directly or indirectly, or Affiliate of more than one Person,
     the Common Stock of two or more of which are and have been so registered,
     "Principal Party" shall refer to whichever of such Persons is the issuer of
      ---------------
     the Common Stock having the greatest aggregate market value; and (C) 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 clauses (A) and (B) above shall
     apply to each of the chains of ownership having an interest in such joint
     venture as if such joint venture were a Subsidiary of each such joint
     venturer 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 Section 13 Event unless the
Principal Party shall have a sufficient number of authorized shares of its
Common Stock that have not been issued or reserved for issuance to permit the
exercise in full of the Rights in

                                       20
<PAGE>

accordance with this Section 13 and unless prior thereto the Company and each
                     ----------
Principal Party and each other Person who may become a Principal Party as a
result of such Section 13 Event 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 such Section 13 Event, the Principal Party at its
own expense shall:

               (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, will use its best efforts to cause such
     registration statement to become effective as soon as practicable after
     such filing and will use its best efforts to cause such registration
     statement to remain effective (with a prospectus at all times meeting the
     requirements of the Act) until the Expiration Date;

               (ii)   use its best efforts to (x) qualify or register the Rights
     and the securities purchasable upon exercise of the Rights under the blue
     sky laws of such jurisdictions as may be necessary or appropriate and (y)
     cause the Rights and the securities purchasable upon exercise of the Rights
     to be listed on any national securities exchange or national quotation
     system upon which its Common Stock is listed, traded or quoted; and

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

The provisions of this Section 13 shall similarly apply to successive mergers or
                       ----------
consolidations or sales or other transfers.  The rights under this Section 13
                                                                   ----------
shall be in addition to the rights to exercise Rights and adjustments under
Section 11(a)(ii) hereof and shall survive any exercise thereunder.
-----------------

          (d)  Notwithstanding anything in this Agreement to the contrary, this
Section 13 shall not be applicable to a transaction described in clauses  (x) or
----------
(y) of Section 13(a) hereof if (i) such transaction is (x) consummated with a
       -------------
Person or Persons who acquired shares of Common Stock pursuant to a Permitted
Offer (or a wholly owned Subsidiary of any such Person or Persons) and (y)
related to such Permitted Offer, (ii) the price per share of Common Stock
offered in such transaction is not less than the price per share of Common Stock
paid to all holders of Common Stock whose shares were purchased pursuant to such
Permitted Offer and (iii) the form of consideration being offered to the
remaining holders of Common Stock pursuant to such transaction is the same as
the form of consideration paid pursuant to such Permitted Offer. Upon
consummation of any such transaction contemplated by this subsection (d), all
                                                          --------------
Rights hereunder shall expire.

     14.  Additional Covenants.
          --------------------

          (a)  The Company covenants and agrees that after the Stock Acquisition
Date it shall not (i) consolidate with, (ii) merge with or into or (iii) sell or
transfer to any other Person, in one or more transactions, assets or earning
power aggregating more than fifty percent (50%)

                                       21
<PAGE>

of the assets or earning power of the Company and its Subsidiaries taken as a
whole, if at the time of or after such consolidation, merger or sale there are
any charter or by-law provisions or any rights, warrants or other instruments
outstanding or any other action taken which would diminish or otherwise
eliminate the benefits intended to be afforded by the Rights. The Company shall
not consummate any such consolidation, merger or sale unless prior thereto the
Company and such other Person shall have executed and delivered to the Rights
Agent a supplemental agreement evidencing compliance with this subsection.

          (b)  The Company covenants and agrees that, after the Stock
Acquisition Date, it will not, except as permitted by Section 24 hereof, take
                                                      ----------
any action the purpose or effect of which is to diminish or otherwise eliminate
the benefits intended to be afforded by the Rights.

     15.  Fractional Rights and Fractional Shares.
          ---------------------------------------

          (a)  The Company shall not be required to issue fractions of Rights,
except prior to the Distribution Date as provided in Section 11(n) hereof, 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 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 15(a), the current
                                                  -------------
market value of a whole Right shall be (except as otherwise provided in the last
sentence of this Section 15(a)) 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 of the Rights for any day shall be
the last sale price, the last quoted price or, if not so quoted, the average of
the high bid and low asked prices in the over-the-counter market, as reported by
The Nasdaq Stock Market 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. 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 reasonably and with good faith to the holders of Rights by the Board
shall be used and shall be binding on the Rights Agent and conclusive for all
purposes.

          (b)  The Company shall not be required to issue fractions of shares of
Preferred Stock (other than fractions which are integral multiples of one one-
thousandth of a share of Preferred Stock) upon exercise of the Rights or to
distribute certificates which evidence fractional shares of Preferred Stock
(other than fractions which are integral multiples of one one-thousandth of a
share of Preferred Stock). Fractions of shares of Preferred Stock in integral
multiples of one one-thousandth of a share of Preferred Stock 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 fractional interests in shares of Preferred
Stock represented by such depositary receipts. In lieu of fractional shares of
Preferred Stock that are not integral multiples of one one-thousandth of a share
of Preferred 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 one-
thousandth of a share of Preferred Stock. For purposes of this Section 15(b),
                                                               -------------
the current market

                                       22
<PAGE>

value of one one-thousandth of a share of Preferred Stock shall be determined in
the manner set forth in Section 11(d) hereof for the Trading Day immediately
                        -------------
prior to the date of such exercise.

          (c)  Following the occurrence of a Triggering Event, 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 a share of Common Stock.  For purposes of this Section
                                                                       -------
15(c), the current market value shall be determined in the manner set forth in
-----
Section 11(d) hereof for the Trading Day immediately prior to the date of such
-------------
exercise.

          (d)  Except as otherwise expressly provided herein, the holder of a
Right by the acceptance of the Right expressly waives such holder's right to
receive any fractional Rights or any fractional shares (other than, in the case
of Preferred Stock, fractions which are integral multiples of one one-thousandth
of a share of Preferred Stock) upon exercise of a Right.  The Rights Agent shall
have no duty or obligation with respect to this Section 15 and Section 24 below
                                                ----------     ----------
unless and until it has received specific instructions (and sufficient cash, if
required) from the Company with respect to its duties or obligations under such
Sections.

     16.  Rights of Action.  All rights of action in respect of this Agreement,
          ----------------
except those rights of action expressly vested in the Rights Agent under this
Agreement, are vested in the respective registered holders of the Rights
Certificates (and, prior to the Distribution Date, the registered holders of the
Common Stock); and any registered holder of any Rights Certificate (or, prior to
the Distribution Date, of the Common Stock), without the consent of the Rights
Agent or of the holder of any other Rights Certificate (or, prior to the
Distribution Date, of the Common Stock), may, in such holder's own behalf and
for such holder's own benefit, enforce, and may institute and maintain any suit,
action or proceeding against the Company to enforce, or otherwise act in respect
of, such holder's 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 by the Company of this
Agreement and shall be entitled to specific performance of the obligations
hereunder and injunctive relief against actual or threatened violations by the
Company of the obligations hereunder of any Person subject to this Agreement.
Holders of Rights shall be entitled to recover the reasonable costs and
expenses, including attorneys' fees, incurred by them in any action to enforce
the provisions of this Agreement.

     17.  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 Common Stock;

          (b)  after the Distribution Date, the Rights Certificates are
transferable only on the registry books of the Rights Agent and only if
surrendered at the office of the Rights Agent

                                       23
<PAGE>

set forth in Section 26 hereof, duly endorsed or accompanied by a proper
             ----------
instrument of transfer and with the appropriate forms and certificates attached;

          (c)  the Company and the Rights Agent shall deem and treat the Person
in whose name a Rights Certificate (or, prior to the Distribution Date, the
associated Common Stock certificate) 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 Common Stock certificate
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

          (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 other Person as a result of the inability of the Company or the
Rights Agent to perform any of its or their obligations under this Agreement by
reason of any preliminary or permanent injunction or other order, decree,
judgment or ruling (whether interlocutory or final) 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; provided, however, that the Company must use its
                                --------  -------
best efforts to have any such order, decree, judgment or ruling lifted or
otherwise overturned as soon as possible.

     18.  Rights Certificate Holder Not Deemed a Shareholder.  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 shares of Preferred Stock, Common
Stock or any other securities of the Company which may at any time be issuable
upon 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 shareholder of the
Company or any right to vote for the election of directors or upon any matter
submitted to shareholders at any meeting thereof, or to give or withhold consent
to any corporate action, or to receive notice of meetings or other actions
affecting shareholders (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 thereof.

     19.  Concerning the Rights Agent.
          ---------------------------

          (a)  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
disbursements and other disbursements incurred in the preparation, delivery,
administration, amendment 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, damage,
judgment, fine, penalty, claim, demand, settlement, cost, or expense (including,
without limitation, the reasonable fees and expenses of legal counsel), incurred
without gross negligence, bad faith or willful misconduct on the part of the
Rights Agent (which gross negligence, bad faith or willful misconduct must be
determined by a final, non-appealable order, judgment, decree or ruling of a
court of competent jurisdiction), for any action taken, suffered or omitted by
the Rights Agent in

                                       24

connection with the acceptance, administration, exercise and performance of this
Agreement, including the costs and expenses of defending against any claim of
liability arising therefrom, directly or indirectly. The costs and expenses
incurred in enforcing this right of indemnification shall be paid by the
Company. The provisions of this Section 19 and Section 21 below shall survive
                                ----------     ----------
the termination of this Agreement, the exercise or expiration of the Rights and
the resignation or removal of the Rights Agent.

          (b)  The Rights Agent shall be authorized to rely on, 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 acceptance and administration
of this Agreement or the exercise or performance of its duties hereunder in
reliance upon any Rights Certificate or certificate for Common Stock 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 21 hereof.
   ----------

     20.  Merger or Consolidation or Change of Name of Rights Agent.
          ---------------------------------------------------------

          (a)  Any Person into which the Rights Agent or any successor Rights
Agent may be merged or with which it may be consolidated, or any Person
resulting from any merger or consolidation to which the Rights Agent or any
successor Rights Agent shall be a party, or any Person succeeding to the
shareholder services 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 Person would be eligible for appointment as a
successor Rights Agent under the provisions of Section 22 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 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.

          (b)  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.

     21.  Rights and Duties of Rights Agent.  The Rights Agent undertakes the
          ---------------------------------
duties and obligations expressly imposed by this Agreement (and not implied
duties or obligations) upon

                                       25
<PAGE>

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 selected by it
(who may be legal counsel for the Company), and the advice or opinion of such
counsel shall be full and complete authorization and protection to the Rights
Agent and the Rights Agent shall incur no liability for or in respect of any
action taken, suffered or omitted by it in good faith and in accordance with
such advice or 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
(including, without limitation, the identity of any Acquiring Person and the
determination of current market price) be proved or established by the Company
prior to taking, suffering or omitting any action hereunder, such fact or matter
(unless other evidence in respect thereof shall be herein specifically
prescribed) may be deemed to be conclusively proved and established by a
certificate signed by the Chief Executive Officer, the President, any Vice
President, the Chief Financial Officer, the Treasurer, any Assistant Treasurer,
the Secretary or any Assistant Secretary of the Company and delivered to the
Rights Agent; and such certificate shall be full authorization to the Rights
Agent and the Rights Agent shall incur no liability for or in respect of any
action taken, suffered or omitted in good faith by it under the provisions of
this Agreement in reliance upon such certificate.

          (c)  The Rights Agent shall be liable hereunder only for its own gross
negligence, bad faith or willful misconduct (which gross negligence, bad faith
or willful misconduct must be determined by a final, non-appealable order,
judgment, decree or ruling of a court of competent jurisdiction).  Anything in
this Agreement to the contrary notwithstanding, in no case will the Rights Agent
be liable for special, indirect, punitive, incidental or consequential loss or
damages of any kind whatsoever (including but not limited to lost profits), even
if the Rights Agent has been advised of the possibility of such damages.
Notwithstanding anything to the contrary herein, the liability of the Rights
Agent hereunder will be limited to the amount of fees paid by the Company to the
Rights Agent hereunder.

          (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 as to the fact that it has countersigned the Rights
Certificates) 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 have any liability for or 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 or liable 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 or liable for any adjustment
required under the provisions of Section 11 or 13 hereof or responsible or
                                 ----------    --
liable for the manner, method or amount of any such adjustment or the
ascertaining of the existence of facts that would require any such adjustment
(except with respect to the exercise of Rights evidenced by Rights Certificates
after

                                       26
<PAGE>

receipt of a certificate pursuant to Section 12 describing any such adjustment);
                                     ----------
nor shall it be responsible or liable for any determination by the Board of the
current market value of the Rights or Preferred Stock or Common Stock pursuant
to the provisions of Section 15 hereof; nor shall it by any act hereunder be
                     ----------
deemed to make any representation or warranty as to the authorization or
reservation of any shares of Preferred Stock or other securities to be issued
pursuant to this Agreement or any Rights Certificate or as to whether any shares
of Preferred Stock or other securities will, when so 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 performance by the Rights Agent of
the provisions of this Agreement.

          (g)  The Rights Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties hereunder and
certificates delivered pursuant to any provision hereof from the Chief Executive
Officer, the President, any Vice President, the Chief Financial Officer, the
Secretary, any Assistant Secretary, the Treasurer or any Assistant Treasurer of
the Company, and is authorized to apply to such officers for advice or
instructions in connection with its duties, and such advice or instructions
shall be full authorization and protection to the Rights Agent and the Rights
Agent shall incur no liability for or in respect of any action taken, suffered
or omitted to be taken by it in good faith in accordance with the advice or
written instructions of any such officer. Any application by the Rights Agent
for written instructions from the Company may, at the option of the Rights
Agent, set forth in writing any action proposed to be taken, suffered or omitted
by the Rights Agent with respect to its duties or obligations under this
Agreement and the date on and/or after which such action shall be taken,
suffered or omitted and the Rights Agent shall not be liable for any action
taken, suffered or omitted in accordance with a proposal included in any such
application on or after the date specified therein (which date shall not be less
than three (3) Business Days after the date any such officer actually receives
such application, unless any such officer shall have consented in writing to an
earlier date) unless, prior to taking, suffering or omitting any such action,
the Rights Agent has received written instructions in response to such
application specifying the action to be taken, suffered or omitted.

          (h)  The Rights Agent and any Affiliate, shareholder, 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 may be interested, or contract with or lend
money to the Company or otherwise act as fully and freely as though it were not
the Rights Agent under this Agreement. Nothing herein shall preclude the Rights
Agent or any such Affiliate, shareholder, director, officer or employee from
acting in any other capacity for the Company or for any other Person.

          (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 (through
its directors, officers and employees) or by or through its attorneys or agents,
and the Rights Agent shall not be answerable or accountable for any act,
omission, default, neglect or misconduct of any such attorneys or agents or for
any loss to the Company or to the holders of the Rights or any other Person
resulting from any such act, omission, default, neglect or misconduct, absent
gross negligence,

                                       27
<PAGE>

bad faith or willful misconduct in the selection and continued employment
thereof (which gross negligence, bad faith or willful misconduct must be
determined by a final, non-appealable order, judgment, decree or ruling of a
court of competent jurisdiction).

          (j)  No provision of this Agreement shall require the Rights Agent to
expend or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder or in the exercise of its rights if
the Rights Agent believes that repayment of such funds or adequate
indemnification against such risk or liability is not reasonably assured to it.

          (k)  If, with respect to any Rights Certificate surrendered to the
Rights Agent for exercise or transfer, the certificate attached to the form of
assignment or form of election to purchase, as the case may be, has either not
been properly completed or indicates an affirmative response to clause l and/or
2 thereof, the Rights Agent shall not take any further action with respect to
such requested exercise or transfer without first consulting with the Company.

     22.  Change of Rights Agent. The Rights Agent or any successor Rights Agent
          ----------------------
may resign and be discharged from its duties under this Agreement upon thirty
(30) days' notice in writing mailed to the Company and to each transfer agent of
the Common Stock and Preferred Stock 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 thirty (30) days' notice in
writing, mailed to the Rights Agent or successor Rights Agent, as the case may
be, and to each transfer agent of the Common Stock and Preferred Stock 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 thirty (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 such holder's 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 (a) a Person organized and doing business under the laws of the United
States or of the State of New York or the State of California (or of any other
state of the United States so long as such Person is authorized to do business
in the State of New York or the State of California), in good standing, which is
authorized under such laws to exercise shareholder services powers and is
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 $50,000,000.00 or (b) an Affiliate of a Person described in
clause (a) of this sentence. After appointment, the successor Rights Agent shall
be vested with the same powers, rights, duties and responsibilities as if it had
been originally named as Rights Agent without further act or deed; but the
predecessor Rights Agent shall deliver and transfer to the successor Rights
Agent any property at the time held by it hereunder, and execute and deliver any
further assurance, conveyance, act or deed necessary for the purpose. Not later
than the effective date of any such appointment the Company shall mail notice
thereof in writing to the predecessor Rights Agent and each transfer agent of
the Common Stock and Preferred Stock, and mail a notice thereof in writing to
the registered holders of the Rights Certificates. Failure to give any notice
provided for in this

                                       28
<PAGE>

Section 22, 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.

     23.  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 the Board to reflect any adjustment or change in the Purchase
Price per share 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. In addition, in connection with the issuance or
sale of shares of Common Stock following the Distribution Date and prior to the
redemption or expiration of the Rights, the Company (a) shall, with respect to
shares of Common Stock so issued or sold pursuant to the exercise of stock
options or otherwise under any employee plan or arrangement, which plan or
arrangement is existing as of the Distribution Date, or upon the exercise,
conversion or exchange of any other securities issued by the Company on or prior
to the Distribution Date, and (b) may, in any other case, if deemed necessary or
appropriate by the Board, issue Rights Certificates representing the appropriate
number of Rights in connection with such issuance or sale; provided, however,
                                                           --------  -------
that (i) no such Rights Certificates shall be issued if, and to the extent that,
the Company shall be advised by counsel that such issuance would create a
significant risk of material adverse tax consequences to the Company or the
Person to whom such Rights Certificates would be issued, and (ii) no such Rights
Certificates shall be issued if, and to the extent that, appropriate adjustment
shall otherwise have been made in lieu of the issuance thereof.

     24.  Redemption, Termination and Exchange.
          ------------------------------------

          (a)  (i)   The Board may, at its option, at any time prior to the
earlier of (x) the Stock Acquisition Date or (y) the Close of Business on the
Final Expiration Date, redeem all but not less than all of the then outstanding
Rights at a redemption price of $0.001 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 Company may, at its option, pay the Redemption Price in
-----------------
any form of consideration deemed appropriate by the Board.

               (ii)  In addition, and notwithstanding the provisions of Section
                                                                        -------
24(a)(i) hereof, the Board may redeem all but not less than all of the then
--------
outstanding Rights at the Redemption Price on or after the Stock Acquisition
Date but prior to any Section 13 Event either (x) in connection with any Section
13 Event in which all holders of Common Stock are treated alike and not
involving (other than as a holder of Common Stock being treated like all other
such holders) an Acquiring Person or an Affiliate or Associate thereof or any
other Person in which such Acquiring Person or Affiliate or Associate thereof
has any interest, or any other Person acting directly or indirectly on behalf of
or in association with any such Acquiring Person or Affiliate or Associate
thereof, or (y) following the occurrence of a Section 11 Event, and the
expiration of any period during which the holder of Rights may exercise the
rights under Section 11(a)(ii) hereof as a result thereof, if and for as long as
             -----------------
any Acquiring Person having triggered the Section 11 Event at issue is not
thereafter the Beneficial Owner of fifteen percent (15%) or

                                       29
<PAGE>

more of the outstanding shares of Common Stock, and at the time of redemption
there are no other Persons who are Acquiring Persons.

          (b)  (i)   In the case of a redemption permitted under Section
                                                                 -------
24(a)(i) hereof, immediately upon the action of the Board ordering the
--------
redemption of the Rights, evidence of which shall have been filed with the
Rights Agent 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. In the case of a redemption
permitted only under Section 24(a)(ii) hereof, evidence of which shall have been
                     -----------------
filed with the Rights Agent, the right to exercise the Rights will terminate and
represent only the right to receive the Redemption Price only after ten (10)
Business Days following the giving of notice of such redemption to the holders
of such Rights if no Section 11 Event shall have occurred, and, if a Section 11
Event shall have occurred, upon the later of ten (10) Business Days following
the giving of such notice or the expiration of any period during which the
rights under Section 11(a)(ii) hereof may be exercised as a result thereof.
             -----------------
Within ten (10) days after the action of the Board ordering any such redemption
of the Rights, the Company shall give notice of such redemption to the Rights
Agent and the holders of the then outstanding Rights by mailing such notice to
the Rights Agent and to all such holders at their last addresses as they appear
upon the registry books of the Rights Agent or, prior to the Distribution Date,
on the registry books of the transfer agent for the Common Stock. Any notice
that is mailed in the manner herein 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.

               (ii)  In the case of a redemption permitted under Section
                                                                 -------
24(a)(i) or (ii), 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 and (ii) mailing payment of the
Redemption Price to the registered holders of the Rights at their last addresses
as they appear on the registry books of the Rights Agent or, prior to the
Distribution Date, on the registry books of the transfer agent of the Common
Stock, and upon such action, all outstanding Rights Certificates shall be null
and void without any further action by the Company.

          (c)  (i)   Subject to the limitations of applicable laws, the Board
may, at its option and at any time after any Person becomes an Acquiring Person,
exchange all or part of the then outstanding and exercisable Rights (which shall
not include Rights that have become null and void pursuant to the provisions of
Section 7(e) hereof) for (A) shares of Common Stock at an exchange ratio of one
------------
share of Common Stock per Right, appropriately adjusted to reflect any stock
split, stock dividend or similar transaction occurring after the date hereof
(the "Exchange Shares"), or (B) Substitute Consideration (as that term is
      ---------------
defined below). The Board may determine, in its sole discretion, whether to
deliver Exchange Shares or Substitute Consideration. Notwithstanding the
foregoing, the Board 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 Stock for or pursuant to the terms of any such plan), together
with all Affiliates and Associates of such Person, becomes the Beneficial Owner
of fifty percent (50%) or more of the Common Stock then outstanding.

                                       30
<PAGE>

               (ii)   In the event the Board shall determine to deliver
Substitute Consideration in exchange for Rights, the Company shall (1) determine
the value of the Exchange Shares (the "Exchange Value"), and (2) with respect to
                                       --------------
each Right to be exchanged, make adequate provision to substitute for Exchange
Shares the following (the "Substitute Consideration"): (v) cash, (w) Common
                           ------------------------
Stock or common stock equivalents (as that term is defined in Section 11(a)(iii)
                                                              ------------------
hereof) or Preferred Stock or equivalent preferred stock (as that term is
defined in Section 11(b) hereof), (x) debt securities of the Company, (y) other
           -------------
assets, or (z) any combination of the foregoing, having an aggregate value equal
to the Exchange Value, where such aggregate value has been determined by the
Board based upon the advice of a nationally recognized investment banking firm
selected by the Board. For purposes of this Section 24(c), the value of a share
                                            -------------
of Common Stock shall be the current market price (as determined pursuant to
Section 11(d) hereof) per share of Common Stock on the day that is the later of
-------------
(x) the first occurrence of a Section 11 Event or (y) the date on which the
Company's right of redemption pursuant to Section 24(a)(i) hereof expires; and
                                          ----------------
the value of any common stock equivalent shall be deemed to have the same value
as the Common Stock on such date.

               (iii)  Immediately upon the action of the Board ordering the
exchange of any Rights pursuant to this Section 24(c), 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
Exchange Shares or Substitute Consideration for each Right exchanged by such
holder.  The Company shall promptly give public notice and notice to the Rights
Agent 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 that 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 Common Stock (or
Substitute Consideration) for Rights will be effected and, in the event of any
partial exchange, the number of Rights which will be exchanged. Any partial
exchange shall be effected pro rata based on the number of Rights (other than
Rights which have become void pursuant to the provisions of Section 7(e) hereof)
                                                            ------------
held by each holder of Rights.

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

               (v)    The Company shall not be required to issue fractions of
shares of Common Stock or to distribute certificates which evidence fractional
shares of Common Stock. In lieu of such fractional shares of Common Stock, the
Company shall pay to the registered holders of the Rights Certificates with
regard to which such fractional shares of Common Stock would otherwise be
issuable an amount in cash equal to the same fraction of the current market
value of a whole share of Common Stock. For the purposes of this Section
                                                                 -------
24(c)(v), the current market value of a whole share of Common Stock shall be
--------
determined in the manner set forth in Section 11(d) hereof for the Trading Day
                                      -------------
immediately prior to the date of exchange pursuant to this Section 24(c).
                                                           -------------

     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 Preferred Stock or to make any other
distribution to the holders of Preferred Stock (other than a regular quarterly
cash dividend out of earnings or retained earnings of the Company), (ii) to
offer to the holders of Preferred Stock rights or warrants to subscribe for or
to purchase any additional shares of Preferred Stock or shares of stock of any
class or any other securities, rights or options, (iii) to effect any
reclassification of Preferred Stock (other than a reclassification involving
only the subdivision of outstanding shares of Preferred Stock), (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 more than fifty percent (50%)
of the assets or earning power of the Company and its Subsidiaries (taken as a
whole) to, any other Person or (v) to effect the liquidation, dissolution or
winding up of the Company, then, in each such case, the Company shall give to
each holder of a Rights Certificate, in accordance with Section 26 hereof, a

     We, Thomas W. Steipp, the Chief Executive Officer, and William Slater, the
Secretary of Symmetricom, Inc., a corporation organized and existing under the
General Corporation Law of the State of California (the "Corporation"), DO
                                                         -----------
HEREBY CERTIFY:

     That we are the duly elected and acting Chief Executive Officer and
Secretary, respectively, of the Corporation; and

     That pursuant to the authority conferred upon the Board of Directors by the
Articles of Incorporation of the Corporation, the Board of Directors on August
7, 2001, adopted the following resolution creating a series of Two Hundred
Thousand (200,000) shares of Preferred Stock designated as Series A
Participating Preferred Stock:

     RESOLVED, that pursuant to the authority vested in the Board of Directors
of the Corporation in accordance with the provisions of its Articles of
Incorporation, a series of Preferred Stock of the Corporation be and it hereby
is created, and that the designation and amount thereof and the powers,
preferences and relative, participating, optional and other special rights of
the shares of such series, and the qualifications, limitations or restrictions
thereof are as follows:

     1.   Designation and Amount.  The shares of such series shall be designated
          ----------------------
as "Series A Participating Preferred Stock," and the number of shares
    --------------------------------------
constituting such series shall be Two Hundred Thousand (200,000). 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
--------
Participating Preferred Stock to a number less than that of the shares then
outstanding plus the number of shares issuable upon exercise of outstanding
rights, options or warrants or upon conversion of outstanding securities issued
by the Corporation.

     2.   Dividends and Distributions.
          ---------------------------

     (A)  Subject to the prior and superior rights of the holders of any shares
of any series of Preferred Stock ranking prior and superior to the shares of
Series A Participating Preferred Stock with respect to dividends, the holders of
shares of Series A Participating Preferred Stock in preference to the holders of
shares of Common Stock (the "Common Stock"), of the Corporation and 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, quarterly
dividends payable in cash on the first day of March, June, September and
December in each year (each such date being

                                      A-1
<PAGE>

referred to herein as a "Quarterly Dividend Payment Date"), commencing on the
                         -------------------------------
first Quarterly Dividend Payment Date after the first issuance of a share or
fraction of a share of Series A Participating Preferred Stock in an amount per
share (rounded to the nearest cent) equal to the greater of (a) $25.00 or, (b)
subject to the provision for adjustment hereinafter set forth, 1,000 times the
aggregate per share amount of all cash dividends, and 1,000 times the aggregate
per share amount (payable in kind) of all non-cash dividends or other
distributions other than a dividend payable in shares of Common Stock or a
subdivision of the outstanding shares of Common Stock (by reclassification or
otherwise), declared on the Common Stock, since the immediately preceding
Quarterly Dividend Payment Date, or, with respect to the first Quarterly
Dividend Payment Date, since the first issuance of any share or fraction of a
share of Series A Participating Preferred Stock. In the event the Corporation
shall at any time after the close of business on August 7, 2001 (the "Rights
                                                                      ------
Declaration Date") (i) declare any dividend on Common Stock payable in shares of
----------------
Common Stock, (ii) subdivide the outstanding Common Stock or (iii) combine the
outstanding Common Stock into a smaller number of shares, by reclassification or
otherwise, then in each such case the amount to which holders of shares of
Series A Participating Preferred Stock were entitled immediately prior to such
event under clause (b) 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.

     (B)  The Corporation shall declare a dividend or distribution on the Series
A Participating Preferred Stock as provided in paragraph (A) above immediately
after it declares a dividend or distribution on the Common Stock (other than a
dividend payable in shares of Common Stock); provided that, in the event no
                                             --------
dividend or distribution shall have been declared on the Common Stock during the
period between any Quarterly Dividend Payment Date and the next subsequent
Quarterly Dividend Payment Date, a dividend of $25.00 per share on the Series A
Participating Preferred Stock shall nevertheless be payable on such subsequent
Quarterly Dividend Payment Date.

     (C)  Dividends shall begin to accrue and be cumulative on outstanding
shares of Series A Participating Preferred Stock from the Quarterly Dividend
Payment Date next preceding the date of issue of such shares of Series A
Participating Preferred Stock unless the date of issue of such shares is prior
to the record date for the first Quarterly Dividend Payment Date, in which case
dividends on such shares shall begin to accrue from the date of issue of such
shares, or unless the date of issue is a Quarterly Dividend Payment Date or is a
date after the record date for the determination of holders of shares of Series
A Participating Preferred Stock entitled to receive a quarterly dividend and
before such Quarterly Dividend Payment Date, in either of which events such
dividends shall begin to accrue and be cumulative from such Quarterly Dividend
Payment Date.  Accrued but unpaid dividends shall not bear interest.  Dividends
paid on the shares of Series A Participating Preferred Stock in an amount less
than the total amount of such dividends at the time accrued and payable on such
shares shall be allocated pro rata on a share-by-share basis among all such
shares at the time outstanding.  The Board of Directors may fix a record date
for the determination of holders of shares of Series A Participating Preferred
Stock entitled to receive payment of a dividend or distribution declared
thereon, which record date shall be no more than 30 days prior to the date fixed
for the payment thereof.

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

     (A)  Subject to the provision for adjustment hereinafter set forth, each
share of Series A Participating Preferred Stock shall entitle the holder thereof
to 1,000 votes on all matters submitted to a vote of the shareholders of the
Corporation.  In the event the Corporation shall at any time after the Rights
Declaration Date (i) declare any dividend on Common Stock payable in shares of
Common Stock, (ii) subdivide the outstanding Common Stock into a greater number
of shares or (iii) combine the outstanding Common Stock into a smaller number of
shares, by reclassification or otherwise, then in each such case the number of
votes per share to which holders of shares of Series A Participating Preferred
Stock were entitled immediately prior to such event shall be adjusted by
multiplying such number 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 outstanding
immediately prior to such event.

     (B)  Except as otherwise provided herein, in the Articles of Incorporation
or by law, the holders of shares of Series A Participating Preferred Stock and
the holders of shares of Common Stock and any other capital stock of the
Corporation having general voting rights shall vote together as one class on all
matters submitted to a vote of shareholders of the Corporation.

     (C)  (i)    If at any time dividends on any Series A Participating
Preferred Stock shall be in arrears in an amount equal to six quarterly
dividends thereon, the holders of the Series A Participating Preferred Stock,
voting as a separate series from all other series of Preferred Stock and classes
of capital stock, shall be entitled to elect two members of the Board of
Directors in addition to any Directors elected by any other series, class or
classes of securities and the authorized number of Directors will automatically
be increased by two. Promptly thereafter, the Board of Directors of this
Corporation shall, as soon as may be practicable, call a special meeting of
holders of Series A Participating Preferred Stock for the purpose of electing
such members of the Board of Directors. Said special meeting shall in any event
be held within 45 days of the occurrence of such arrearage.

          (ii)   During any period when the holders of Series A Participating
Preferred Stock, voting as a separate series, shall be entitled and shall have
exercised their right to elect two Directors, then and during such time as such
right continues (a) the then authorized number of Directors shall remain
increased by two, and the holders of Series A Participating Preferred Stock,
voting as a separate series, shall remain entitled to elect the additional
Directors so provided for, and (b) each such additional Director shall not be a
member of any existing class of the Board of Directors, but shall serve until
the next annual meeting of shareholders for the election of Directors, or until
his or her successor shall be elected and shall qualify, or until his or her
right to hold such office terminates pursuant to the provisions of this Section
                                                                        -------
3(C).
----

          (iii)  A Director elected pursuant to the terms hereof may be removed
with or without cause by the holders of Series A Participating Preferred Stock
entitled to vote in an election of such Director.

                                      A-3
<PAGE>

          (iv)   If, during any interval between annual meetings of shareholders
for the election of Directors and while the holders of Series A Participating
Preferred Stock shall be entitled to elect two Directors, there are fewer than
two such Directors in office by reason of resignation, death or removal, then,
promptly thereafter, the Board of Directors shall call a special meeting of the
holders of Series A Participating Preferred Stock for the purpose of filling
such vacancy(ies) and such vacancy(ies) shall be filled at such special meeting.
Such special meeting shall in any event be held within 45 days of the occurrence
of any such vacancy(ies).

          (v)    At such time as the arrearage is fully cured, and all dividends
accumulated and unpaid on any shares of Series A Participating Preferred Stock
outstanding are paid, and, in addition thereto, at least one regular dividend
has been paid subsequent to curing such arrearage, the term of office of any
Director elected pursuant to this Section 3(C), or his or her successor, shall
                                  -------------
automatically terminate, and the authorized number of Directors shall
automatically decrease by two, and the rights of the holders of the shares of
the Series A Participating Preferred Stock to vote as provided in this Section
                                                                       -------
3(C) shall cease, subject to renewal from time to time upon the same terms and
----
conditions.

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

     4.   Certain Restrictions.
          --------------------

     (A)  Whenever quarterly dividends or other dividends or distributions
payable on the Series A Participating Preferred Stock as provided in Section 2
                                                                     ---------

distributions, whether or not declared, on shares of Series A Participating
Preferred Stock outstanding shall have been paid in full, the Corporation shall
not:

ranking junior (either as to dividends or upon liquidation, dissolution or
winding up) to the Series A Participating Preferred Stock;

          (ii)   declare or pay dividends on or make any other distributions on
any shares of stock ranking on a parity (either as to dividends or upon
liquidation, dissolution or winding up) with the Series A Participating
Preferred Stock except dividends paid ratably on the Series A Participating
Preferred Stock and all such parity stock on which dividends are payable or in
arrears in proportion to the total amounts to which the holders of all such
shares are then entitled;

          (iii)  redeem or purchase or otherwise acquire for consideration
shares of any stock ranking on a parity (either as to dividends or upon
liquidation, dissolution or winding up) with the Series A Participating
Preferred Stock provided that the Corporation may at any time redeem, purchase
or otherwise acquire shares of any such parity stock in exchange for shares of

                                      A-4
<PAGE>

any stock of the Corporation ranking junior (either as to dividends or upon
dissolution, liquidation or winding up) to the Series A Participating Preferred
Stock; or

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

     (B)  The Corporation shall not permit any subsidiary of the Corporation to
purchase or otherwise acquire for consideration any shares of stock of the
Corporation unless the Corporation could, under paragraph (A) of this Section 4,
                                                                      ---------
purchase or otherwise acquire such shares at such time and in such manner.

     5.   Reacquired Shares. Any shares of Series A Participating Preferred
          -----------------
Stock purchased or otherwise acquired by the Corporation in any manner
whatsoever shall be retired and canceled 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 to be created by resolution or resolutions of the Board of
Directors, subject to the conditions and restrictions on issuance set forth
herein.

     6.   Liquidation, Dissolution or Winding Up.
          --------------------------------------

     (A)  Upon any liquidation (voluntary or otherwise), dissolution or winding
up of the Corporation, no distribution shall be made to the holders of shares of
stock ranking junior (either as to dividends or upon liquidation, dissolution or
winding up) to the Series A Participating Preferred Stock unless, prior thereto,
the holders of shares of Series A Participating Preferred Stock shall have
received per share, the greater of $1,000.00 or 1,000 times the payment made per
share of Common Stock, plus an amount equal to accrued and unpaid dividends and
distributions thereon, whether or not declared, to the date of such payment (the
"Series A Liquidation Preference").  Following the payment of the full amount of
 -------------------------------
the Series A Liquidation Preference, no additional distributions shall be made
to the holders of shares of Series A Participating Preferred Stock unless, prior
thereto, the holders of shares of Common Stock shall have received an amount per
share (the "Common Adjustment") equal to the quotient obtained by dividing (i)
            -----------------
the Series A Liquidation Preference by (ii) 1,000 (as appropriately adjusted as
set forth in subparagraph (C) below to reflect such events as stock splits,
stock dividends and recapitalization with respect to the Common Stock) (such
number in clause (ii), the "Adjustment Number").  Following the payment of the
                            -----------------
full amount of the Series A Liquidation Preference and the Common Adjustment in
respect of all outstanding shares of Series A Participating Preferred Stock and
Common Stock, respectively, holders of Series A Participating Preferred Stock
and holders of shares of Common Stock shall receive their ratable and
proportionate share of the remaining assets to be distributed in the ratio of
the Adjustment Number to 1 with respect to such Preferred Stock and Common
Stock, on a per share basis, respectively.

                                   A-5
<PAGE>

     (B)  In the event there are not sufficient assets available to permit
payment in full of the Series A Liquidation Preference and the liquidation
preferences of all other series of Preferred Stock, if any, which rank on a
parity with the Series A Participating Preferred Stock, then such remaining
assets shall be distributed ratably to the holders of such parity shares in
proportion to their respective liquidation preferences.  In the event, following
payment in full of all liquidation preferences of all shares senior to Common
Stock (including the Series A Participating Preferred Stock), there are not
sufficient assets available to permit payment in full of the Common Adjustment,
then the remaining assets shall be distributed ratably to the holders of Common
Stock.

     (C)  In the event the Corporation shall at any time after the Rights
Declaration Date (i) declare any dividend on Common Stock payable in shares of
Common Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, by reclassification or
otherwise, then in each such case the Adjustment Number in effect immediately
prior to such event shall be adjusted by multiplying such Adjustment Number 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.

     7.   Consolidation, Merger, etc.  In case the Corporation shall enter into
          --------------------------
any consolidation, merger, combination or other transaction in which the shares
of Common Stock are exchanged for or changed into other stock or securities,
cash and/or any other property, then in any such case the shares of Series A
Participating Preferred Stock shall at the same time be similarly exchanged or
changed in an amount per share (subject to the provision for adjustment
hereinafter set forth) equal to 1,000 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 Corporation shall at any time after the Rights Declaration Date
(i) declare any dividend on Common Stock payable in shares of Common Stock, (ii)
subdivide the outstanding Common Stock, or (iii) combine the outstanding Common
Stock into a smaller number of shares, 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 Participating 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 are outstanding immediately prior to
such event.

     8.   Redemption. The shares of Series A Participating Preferred Stock shall
          ----------
not be redeemable.

     9.   Ranking.  The Series A Participating Preferred Stock shall rank junior
          -------
to all other series of the Corporation's Preferred Stock as to the payment of
dividends and the distribution of assets, unless the terms of any such series
shall provide otherwise.

     10.  Amendment.  The Articles of Incorporation and the By-Laws of the
          ---------
Corporation shall not be further amended in any manner which would materially
alter or change the powers, preferences or special rights of the Series A
Participating Preferred Stock so as to affect them

                                      A-6
<PAGE>

adversely without the affirmative vote of the holders of at least 66-2/3% of the
outstanding shares of Series A Participating Preferred Stock voting separately
as a class.

     11.  Fractional Shares.  Series A Participating Preferred Stock may be
          -----------------
issued in fractions of a share which shall entitle the holder, in proportion to
such holder's fractional shares, to exercise voting rights, receive dividends,
participate in distributions and to have the benefit of all other rights of
holders of Series A Participating Preferred Stock.

     IN WITNESS WHEREOF, the undersigned have executed this Certificate as of
the [XX] day of August, 2001.

surrender at the office of the Rights Agent designated for such purpose, may be
exchanged for another Rights Certificate or Rights Certificates of like tenor

"Preferred Stock"), at a price of Seventy-Two and 82/100ths Dollars ($72.82) per
----------------                  ------------------------------------------
one one-thousandth of a 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 Mellon Investor Services LLC, as
 ----------------
"Rights Agent."
-------------

     Initially, the Rights will be attached to all Common Stock certificates
representing shares then outstanding, and no separate Rights certificates will
be distributed.  The Rights will separate from the Common Stock and a
"Distribution Date" will occur upon the earliest of the following: (i) a public
------------------
announcement that a person, entity or group of affiliated or associated persons
and/or entities (an "Acquiring Person") has acquired, or obtained the right to
                     ----------------
acquire, beneficial ownership of fifteen percent (15%) or more of the
outstanding shares of Common Stock (other than (A) as a result of repurchases of
stock by the Company or certain inadvertent actions by institutional or certain
other shareholders, (B) the Company, any subsidiary of the Company or any
employee benefit plan of the Company or any subsidiary and (C) certain other
instances set forth in the Rights Agreement); or (ii) ten (10) business days
(unless such date is extended by the Board of Directors) following the
commencement of a tender offer or exchange offer which would result in any
person, entity or group of affiliated or associated persons and/or entities
becoming an Acquiring Person (unless such tender offer or exchange offer is a
Permitted Offer (defined below)).

     Until the Distribution Date (or earlier redemption or expiration of the
Rights, if applicable), (i) the Rights will be evidenced by certificates for
Common Stock and will be transferred only with such Common Stock certificates,
(ii) new Common Stock certificates issued after the Record Date upon transfers
or new issuances of the Common Stock will contain a notation incorporating the
Rights Agreement by reference and (iii) the surrender for transfer of any
certificates for outstanding Common Stock will also constitute the transfer of
the Rights associated with such Common Stock.  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 Stock as of the
------------
close of business on the Distribution Date, and the separate Rights Certificates
alone will evidence the Rights.

     The Rights are not exercisable until the Distribution Date.  The Rights
will expire on the earliest of (i) August 9, 2011, (ii) consummation of a merger
transaction with a person, entity or group who (x) acquired Common Stock
pursuant to a Permitted Offer (as defined below) and (y) is offering in the
merger the same price per share and form of consideration paid in the Permitted
Offer or (iii) redemption or exchange of the Rights by the Company as described
below.

                                      C-1
<PAGE>

     The number of Rights associated with each share of Common Stock shall be
proportionately adjusted to prevent dilution in the event of a stock dividend
on, or a subdivision, combination or reclassification of, the Common Stock.  The
Purchase Price payable, and the number of one one-thousandths of a share of
Preferred Stock 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 Stock, (ii) upon the grant to holders of the
Preferred Stock of certain rights, options or warrants to subscribe for
Preferred Stock, certain convertible securities or securities having the same or
more favorable rights, privileges and preferences as the Preferred Stock at less
than the current market price of the Preferred Stock or (iii) upon the
distribution to holders of the Preferred Stock of evidences of indebtedness or
assets (excluding regular quarterly cash dividends out of earnings or retained
earnings) or of subscription rights, options or warrants (other than those
referred to above).  With certain exceptions, no adjustments in the Purchase
Price will be required until cumulative adjustments require an adjustment of at
least one percent (1%) in such Purchase Price.

     In the event that, after the first date of public announcement by the
Company or an Acquiring Person that an Acquiring Person has become such, the
Company is involved in a merger or other business combination transaction
(whether or not the Company is the surviving corporation) or fifty percent (50%)
or more of the Company's assets or earning power are sold (in one transaction or
a series of transactions), proper provision shall be made so that each holder of
a Right (other than an Acquiring Person) shall thereafter have the right to
receive, upon the exercise thereof at the then current Purchase Price, that
number of shares of common stock of either the Company, in the event that it is
the surviving corporation of a merger or consolidation, or the acquiring company
(or, in the event there is more than one acquiring company, the acquiring
company receiving the greatest portion of the assets or earning power
transferred) which at the time of such transaction would have a market value of
two (2) times the Purchase Price (such right being called the "Merger Right").
                                                               ------------
In the event that a person, entity or group becomes an Acquiring Person (unless
pursuant to a tender offer or exchange offer for all outstanding shares of
Common Stock at a price and on terms determined prior to the date of the first
acceptance of payment for any of such shares by at least a majority of the
members of the Board of Directors who are not officers of the Company and are
not Acquiring Persons (or affiliated or associated persons and/or entities
thereof) to be fair to and in the best interests of the Company and its
shareholders (a "Permitted Offer")), then proper provision shall be made so that
                 ---------------
each holder of a Right will, for a sixty (60) day period (subject to extension
under certain circumstances) thereafter, have the right to receive upon exercise
that number of shares of Common Stock (or, at the election of the Company, which
election may be obligatory if sufficient authorized shares of Common Stock are
not available, a combination of Common Stock, property, other securities (e.g.,
                                                                          ----
Preferred Stock) and/or cash (including by way of a reduction in the Purchase
Price)) having a market value of two (2) times the Purchase Price (such right
being called the "Subscription Right").  The holder of a Right will continue to
                  ------------------
have the Merger Right whether or not such holder exercises the Subscription
Right.  Notwithstanding the foregoing, upon the occurrence of any of the events
giving rise to the exercisability of the Merger Right or the Subscription Right,
any Rights that are or were at any time after the Distribution Date owned by an
Acquiring Person (or affiliated or associated persons and/or entities thereof)
shall immediately become null and void.

                                      C-2
<PAGE>

     At any time prior to the earlier to occur of (i) a person, entity or group
becoming an Acquiring Person or (ii) the expiration of the Rights, the Company
may redeem the Rights in whole, but not in part, at a price of $0.001 per Right
(the "Redemption Price"), which redemption shall be effective upon the action of
      ----------------
the Board of Directors.  Additionally, the Company may, following a person,
entity or group becoming an Acquiring Person, redeem the then outstanding Rights
in whole, but not in part, at the Redemption Price (i) if such redemption is
incidental to a merger or other business combination transaction or series of
transactions involving the Company but not involving an Acquiring Person (or
certain related persons and/or entities) or (ii) following an event giving rise
to, and the expiration of the exercise period for, the Subscription Right if and
for as long as the Acquiring Person triggering the Subscription Right
beneficially owns securities representing less than fifteen percent (15%) of the
outstanding shares of Common Stock and at the time of redemption there are no
other Acquiring Persons.  The redemption of Rights described in the preceding
sentence shall be effective only as of such time when the Subscription Right is
not exercisable.  Upon the effective date of the 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.

     Subject to applicable law, the Board of Directors, at its option, may at
any time after a person, group or entity becomes an Acquiring Person (but not
after the acquisition by such Acquiring Person of fifty percent (50%) or more of
the outstanding shares of Common Stock), exchange all or part of the then
outstanding and exercisable Rights (except for Rights which have become void)
for shares of Common Stock at a rate of one share of Common Stock per Right
(subject to adjustment) or, alternatively, for substitute consideration
consisting of cash, securities of the Company or other assets (or any
combination thereof).

     The Preferred Stock purchasable upon exercise of the Rights will be
nonredeemable and junior to any other series of preferred stock the Company may
issue (unless otherwise provided in the terms of such stock).  Each share of
Preferred Stock will have a preferential quarterly dividend in an amount equal
to 1,000 times the dividend declared on each share of Common Stock, but in no
event less than $25.00.  In the event of liquidation, the holders of shares of
Preferred Stock will receive a preferred liquidation payment equal, per share,
to the greater of $1,000.00 or 1,000 times the payment made per share of Common
Stock.  Each share of Preferred Stock will have 1,000 votes, voting together
with the shares of Common Stock.  In the event of any merger, consolidation or
other transaction in which shares of Common Stock are exchanged, each share of
Preferred Stock will be entitled to receive 1,000 times the amount and type of
consideration received per share of Common Stock.  The rights of the Preferred
Stock as to dividends, liquidation and voting, and in the event of mergers and
consolidations, are protected by customary antidilution provisions.  Fractional
shares of Preferred Stock will be issuable; however, the Company may elect to
                                            -------
(i) distribute depositary receipts in lieu of such fractional shares and (ii)
make an adjustment in cash, in lieu of fractional shares other than fractions
that are multiples of one one-thousandth of a share, based on the market price
of the Preferred Stock prior to the date of exercise.

     Until a Right is exercised, the holder thereof, as such, will have no
rights as a shareholder of the Company, including, without limitation, the right
to vote or to receive dividends.  While the distribution of the Rights should
not be taxable to shareholders or to the Company, holders of Rights may,
depending upon the circumstances, recognize taxable income in the event (i) that
the

                                      C-3
<PAGE>

Rights become exercisable for (x) Common Stock or Preferred Stock (or other
consideration) or (y) common stock of an acquiring company in the instance of
the Merger Right as set forth above or (ii) of any redemption or exchange of the
Rights as set forth above.

     The Company and the Rights Agent retain broad authority to amend the Rights
Agreement; however, following any Distribution Date any amendment may not
           -------
adversely affect the interests of holders of Rights.

     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.  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
INCORPORATED HEREIN BY REFERENCE.
