         2.       Shelf Registration Statement.

                  (a) The Company agrees to file with the SEC as soon as
reasonably practicable after the Closing Date, but in no event later than the
Filing Date a Registration Statement for an offering to be made on a continuous
basis pursuant to Rule 415, covering all of the Transfer Restricted Securities
or separate Registration Statements for an offering to be made on a continuous
basis pursuant to Rule 415 covering all of the Notes constituting Transfer
Restricted Securities and all of the Common Stock constituting Transfer
Restricted Securities, respectively (such Registration Statement or Statements,
collectively, the "Shelf Registration Statement"). The Shelf Registration
Statement shall be on Form S-3 under the Securities Act or another appropriate
form selected by the Company permitting registration of such Transfer Restricted
Securities for resale by the Holders in the manner or manners reasonably
designated by Holders of a majority in aggregate principal amount of Transfer
Restricted Securities being sold (including, without limitation, up to two
underwritten offerings). The Company shall not permit any securities other than
the Transfer Restricted Securities to be included in the Shelf Registration
Statement. The Company shall use its reasonable best efforts to cause the Shelf
Registration Statement to be declared effective pursuant to the Securities Act
as soon as reasonably practicable following the filing thereof and to keep the
Shelf Registration Statement continuously effective under the Securities Act for
two years after the latest date of original issuance of any of the Notes
(subject to extension pursuant to Sections 2(d) hereof) (the "Effectiveness
Period"), or such shorter period ending when there cease to be any Transfer
Restricted Securities outstanding.

                  (b) Supplements and Amendments. The Company shall use its
reasonable best efforts to keep the Shelf Registration Statement continuously
effective by supplementing and amending the Shelf Registration Statement if
required by the rules, regulations or instructions applicable to the
registration form used for the Shelf Registration Statement, if required by the
Securities Act or if reasonably requested by the Holders of a majority in
aggregate principal amount of the Transfer Restricted Securities or by any
underwriter of such Transfer Restricted Securities; provided, however, that the
Effectiveness Period shall be extended as provided in Section 2(d) hereof.

                  (c) Selling Securityholder Information. Each Holder of
Transfer Restricted Securities agrees that if such Holder wishes to sell
Transfer Restricted Securities pursuant to the Shelf Registration Statement and
related Prospectus, it will do so only in accordance with this Section 2. Each
Holder of Transfer Restricted Securities wishing to sell Transfer Restricted
Securities pursuant to the Shelf Registration Statement and related Prospectus
agrees to deliver a Notice and Questionnaire that includes such information
regarding the distribution of its Transfer Restricted Securities as is required
by law to be disclosed by the Holder in the Shelf Registration Statement (the
"Requisite Information") to the Company prior to any intended distribution of
Transfer Restricted Securities under the Shelf Registration Statement. From and
after the date the Shelf Registration Statement becomes effective, the Company
shall, as promptly as is practicable after the date a Notice and Questionnaire
is delivered, and in any event within five (5) Business Days after such date,
(i) if required by applicable law, file with the SEC a post-effective amendment
to the Shelf Registration Statement or prepare and, if required by applicable
law, file

                                     - 5 -
<PAGE>   7
a supplement to the related Prospectus or a supplement or amendment to any
document incorporated therein by reference or file any other required document
so that the Holder delivering such Notice and Questionnaire is named as a
selling securityholder in the Shelf Registration Statement and the related
Prospectus in such a manner as to permit such Holder to deliver such Prospectus
to purchasers of the Transfer Restricted Securities in accordance with
applicable law and, if the Company shall file a post-effective amendment to the
Shelf Registration Statement, use its reasonable best efforts to cause such
post-effective amendment to be declared effective under the Securities Act as
promptly as is practicable, but in any event by the date that is forty-five (45)
days after the date such post-effective amendment is required by this clause to
be filed; (ii) provide such Holder copies of any documents filed pursuant to
Section 2(c)(i); and (iii) notify such Holder as promptly as practicable after
the effectiveness under the Securities Act of any post-effective amendment filed
pursuant to Section 2(c)(i); provided, that if such Notice and Questionnaire is
delivered during a time that the use of the Prospectus is suspended pursuant to
Section 2(d), the Company shall so inform the Holder delivering such Notice and
Questionnaire and shall take the actions set forth in clauses (i), (ii) and
(iii) above upon such time the use of the Prospectus may be resumed, provided,
further, that if under applicable law the Company has more than one option as to
the type or manner of making any such filing, it will make the required filing
or filings in the manner or of a type reasonably expected to result in the
earliest availability of the Prospectus for effecting resales of the Holder's
Transfer Restricted Securities.

                  If any such Registration Statement refers to any Holder by
name or otherwise as the holder of any securities of the Company, then such
Holder shall have the right to require, in the event that such reference to such
Holder by name or otherwise is not required by the Securities Act or any similar
Federal statute then in force, the deletion of the reference to such Holder in
such Registration Statement.

                  (d) Certain Notices; Suspension of Sales. Each Holder agrees
by acquisition of such Transfer Restricted Securities that, upon receipt of any
notice from the Company of the happening of any event of the kind described in
Section 4(c)(ii), 4(c)(iii), 4(c)(v) or 4(c)(vi) hereof, such Holder will
forthwith discontinue disposition of such Transfer Restricted Securities covered
by the Registration Statement and Prospectus (other than in transactions exempt
from the registration requirements under the Securities Act) until such Holder's
receipt of the copies of the supplemented or amended Prospectus contemplated by
Sections 4(c)(i) and 4(k) hereof, or until it is advised in writing (the
"Advice") by the Company that the use of the applicable Prospectus may be
resumed, and, in either case, has received copies of any additional or
supplemental filings that are incorporated or deemed to be incorporated by
reference in such Prospectus. If the Company shall give any such notice, the
Effectiveness Period shall be extended by the number of days during such period
from and including the date of the giving of such notice to and including the
date when each Holder shall have received (x) the copies of the supplemented or
amended Prospectus contemplated by Sections 4(c)(i) and 4(k) hereof or (y) the
Advice, and, in either case, has received copies of any additional or
supplemental filings that are incorporated or deemed to be incorporated by
reference in such Prospectus.

                  (e) Material Events; Suspension of Sales. Notwithstanding the
provisions contained in this Section 2, in the event that, in the judgment of
the Company's Board of Directors, it is advisable to suspend use of the
Prospectus due to pending corporate developments, public filings with the SEC or
similar events, the Company shall promptly deliver a written certificate to each
registered Holder, the Special Counsel and the managing underwriters, if any, to
the effect that the use of the Prospectus is to be suspended until the Company
shall deliver a written notice that the use of the Prospectus may be resumed.
Thereafter, the use of the Prospectus shall be suspended, and the Company shall
not be required to maintain the effectiveness of, or amend or update the Shelf
Registration Statement, or amend or supplement the Prospectus; provided,
however, that the Company shall only be permitted to suspend the use of the
Prospectus for a period not to exceed 30 days in any six-month period or two
periods not to exceed an aggregate of 60 days in any 12-month period. The
Company will use its best efforts to ensure that the use of the Prospectus may
be resumed as soon as, in the judgment of the Company's Board of Directors,
disclosure of the material relating to such pending development, filing or event
would not have a materially adverse effect on the Company. If the Company shall
give any such suspension notice pursuant to this Section 2(e), the Effectiveness
Period shall be extended by the number of days during such period from and
including the date of giving such notice to and including the date when each
Holder shall have received notice that use of the Prospectus may be resumed.

         3.       Liquidated Damages.

                  (a) The Company and the Purchasers agree that the Holders will
suffer damages if the Company fails to fulfill its obligations pursuant to
Section 2 hereof and that it would not be possible to ascertain the extent of
such damages. Accordingly, the Company hereby agrees to pay liquidated damages
("Liquidated Damages") under the circumstances and to the extent set forth
below:

                               (i) to each Holder if the Shelf Registration
                  Statement has not been filed with the SEC on or prior to the
                  Filing Date; or

                               (ii) to each Holder if each Shelf Registration
                  Statement is not declared effective by the SEC on or prior to
                  the applicable Effectiveness Target Date;

                               (iii) to each Holder if the Shelf Registration
                  Statement ceases to be effective or usable at any time during
                  the Effectiveness Period (without being succeeded on the same
                  day immediately by a post-effective amendment or supplement to
                  the Shelf Registration Statement that cures such failure and
                  that is itself, in the case of post-effective amendment,
                  immediately declared effective) for a period of time which
                  shall exceed 90 days in the aggregate in any period of 365
                  consecutive days; or

                               (iv) to the particular Holder affected by the
                  Company's failure to perform its obligations set forth in
                  Section 2(c) within the time period required therein;

                                     - 7 -
<PAGE>   9
(any of the foregoing, a "Registration Default"); provided that the fact that a
Shelf Registration Statement is not usable by a particular Holder at any given
time solely as a result of the failure of such Holder to provide Requisite
Information with respect to it shall not be relevant for purposes of clause
(iii) above unless such Holder shall have provided such information to the
Company and the Company shall have failed to file an appropriate Prospectus
supplement or post-effective amendment to the Shelf Registration Statement. In
the event of any such Registration Default, the Company shall accrue Liquidated
Damages to each applicable Holder during the first 90-day period immediately in
an amount equal to $.05 per week per $1,000 principal amount of Notes held by
such Holder and, if applicable, on an equivalent basis per share (subject to
adjustment in the event of any stock split, stock combination, stock dividends
and the like) of Common Stock constituting Transfer Restricted Securities held
by such Holder for each week or portion thereof that the Registration Default
continues. The weekly rate at which such Liquidated Damages accrue shall
increase by an additional $.05 per $1,000 principal amount of Notes and, if
applicable, an equivalent amount per week per share (subject to adjustment as
set forth above) of Common Stock constituting Transfer Restricted Securities for
each subsequent continuing 90-day period following the occurrence of such
Registration Default until all Registration Defaults have been cured; provided,
however, that Liquidated Damages shall not at any time exceed $.25 per week per
$1,000 principal amount of Notes or, as applicable, an equivalent amount per
week per share (subject to adjustment as set forth above) of Common Stock
constituting Transfer Restricted Securities. In no event shall the Company be
required to pay Liquidated Damages in excess of the applicable maximum weekly
amount, regardless of whether one or multiple Registration Defaults shall exist.
Following the cure of all Registration Defaults, the accrual of Liquidated
Damages shall cease (without in any way limiting the effect of any subsequent
Registration Default). A Registration Default under clause (i) above shall be
cured on the date that the applicable Shelf Registration Statement is filed with
the SEC; a Registration Default under clause (ii) above shall be cured on the
date that the applicable Shelf Registration Statement is declared effective by
the SEC; a Registration Default under clause (iii) above shall be cured on the
date the applicable Shelf Registration Statement is declared effective or
otherwise usable; and a Registration Default under clause (iv) above shall be
cured on the date the applicable prospectus supplement to the Shelf Registration
Statement is filed or the post-effective amendment with respect to such Shelf
Registration Statement is declared effective.

                  (b) The Company shall notify the Trustee within one Business
Day after each and every date on which a Registration Default occurs. Liquidated
Damages shall be paid by the Company to the Record Holders on each Damages
Payment Date in the same manner as interest is paid under the Indenture, in the
case of the Notes, and by mailing checks to their registered addresses in the
register of the Company for the Common Stock, in the case of shares of Common
Stock; provided, however, that any Liquidated Damages accrued with respect to
any Note or portion thereof called for redemption on a redemption date,
repurchased in connection with a Repurchase Event (as defined in the Indenture)
on a repurchase date, or converted into shares of Common Stock on a conversion
date prior to the Damages Payment Date, shall, in any such event, be paid
instead to the Holder who submitted such Note or portion thereof for redemption,
repurchase or conversion on the applicable redemption date, repurchase date or
conversion date, as the case may be, on such date (promptly following the
conversion date, in the case of conversion of a Note).

<PAGE>   10
                  (c) All of the Company's obligations set forth in this Section
3 which are unsatisfied to any extent with respect to any Transfer Restricted
Securities at the time such security ceases to be a Transfer Restricted Security
shall survive until such time as all such obligations with respect to such
security have been satisfied in full (notwithstanding the earlier termination of
this Agreement).

                  (d) Any payments due and payable pursuant to this Section 3
with respect to any Notes shall be subject to the provisions of Article IV of
the Indenture as if such payments were additional interest on the Notes.

                  (e) The parties hereto agree that the Liquidated Damages
provided for in this Section 3 constitute a reasonable estimate of the damages
that may be incurred by holders of record of Transfer Restricted Securities by
reason of the failure of the Shelf Registration Statement to be filed or
declared effective or unavailable (absolutely or as a practical matter) for
effecting resales of Transfer Restricted Securities in accordance with the
provisions hereof. Notwithstanding the foregoing, the parties agree that the
sole contractual damages payable for a violation of the terms of this Agreement
with respect to which Liquidated Damages are expressly provided shall be such
Liquidated Damages. Nothing in this Section 3(e), however, shall preclude a
holder of Transfer Restricted Securities from pursuing or obtaining specific
performance or other equitable relief with respect to the Company's failure to
pay Liquidated Damages pursuant to this Agreement.

         4. Registration Procedures. In connection with the Company's
registration obligations hereunder, the Company shall effect such registrations
on the appropriate form selected by the Company to permit the resale of Transfer
Restricted Securities in accordance with the intended method or methods of
disposition thereof, and pursuant thereto the Company shall as expeditiously as
reasonably possible:

                  (a) No fewer than five Business Days prior to the initial
filing of a Registration Statement or Prospectus and no fewer than two Business
Days prior to the filing of any amendment or supplement thereto, furnish to the
registered Holders (determined as of the most recent reasonably practicable date
which shall not be more than two Business Days prior to the date such document
is personally delivered, delivered to a next-day courier, deposited in the mail
or telecopied, as the case may be), Special Counsel and the managing
underwriters, if any, copies of all such documents proposed to be filed
(excluding, unless requested, those incorporated or deemed to be incorporated by
reference and then only to the Holder who so requested) and cause the officers
and directors of the Company, counsel to the Company and independent certified
public accountants to the Company to respond to such inquiries as shall be
necessary in connection with such Registration Statement, in the opinion of
Special Counsel and counsel to such underwriters, to conduct a reasonable
investigation within the meaning of the Securities Act. The Company shall not
file any such Registration Statement or related Prospectus or any amendments or
supplements thereto to which the Holders of a majority in aggregate principal
amount of the Transfer Restricted Securities, Special Counsel, or the managing
underwriters, if any, shall reasonably object on a timely basis;

                                     - 9 -
<PAGE>   11
                  (b) Prepare and file with the SEC such amendments, including
post-effective amendments, to each Registration Statement as may be necessary to
keep such Registration Statement continuously effective for the applicable time
period set forth in Section 2(a) hereof in case of the Shelf Registration
Statement and in case of any underwritten offering the period of distribution of
Transfer Restricted Securities covered by such Registration Statement; cause the
related Prospectus to be supplemented by any required Prospectus supplement, and
as so supplemented to be filed pursuant to Rule 424 under the Securities Act
with respect to the disposition of all securities covered by such Registration
Statement during such period in accordance with the intended method or methods
of disposition by the Holder set forth in such Registration Statement as so
amended or in such Prospectus as so supplemented (including, without limitation,
the filing of any Prospectus supplement pursuant to Rule 424 in order to add or
change any selling security holder information (including any such supplements
or amendments pursuant to Section 2(c) hereof, provided such Holder to which
such change applies complies with the Requisite Information requirements of
Section 2(c) hereof));

                  (c) Notify the registered (as of the most recent reasonably
practicable date which shall not be more than two Business Days prior to the
date such notice is personally delivered, delivered to a next-day courier,
deposited in the mail or telecopied, as the case may be) Holders, Special
Counsel and the managing underwriters, if any, promptly (and in the case of an
event specified by clause (i)(A) of this paragraph in no event fewer than two
Business Days prior to such filing), and (if requested by any such person),
confirm such notice in writing, (i)(A) when a Prospectus or any Prospectus
supplement or post-effective amendment is proposed to be filed, and, (B) with
respect to a Registration Statement or any post-effective amendment, when the
same has become effective, (ii) of any request of the SEC or any other Federal
or state governmental authority for amendments or supplements to such
Registration Statement or related Prospectus or for additional information
related thereto, (iii) of the issuance by the SEC, any state securities
commission, any other governmental agency or any court of any stop order, order
or injunction suspending or enjoining the use or the effectiveness of the
Registration Statement or the initiation of any proceedings for that purpose,
(iv) if at any time any of the representations and warranties of the Company
contained in any agreement (including any underwriting agreement) contemplated
by Section 4(m) hereof are not true and correct in all material respects during
the effectiveness of such agreement, (v) of the receipt by the Company of any
notification with respect to the suspension of the qualification or exemption
from qualification of any of the Transfer Restricted Securities for sale in any
jurisdiction, or the initiation or threatening of any proceeding for such
purpose, and (vi) of the existence of any fact and the happening of any event
that makes any statement made in such Registration Statement or related
Prospectus untrue in any material respect, or that requires the making of any
changes in such Registration Statement or Prospectus so that in the case of the
Registration Statement, it will not contain any 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 and that, in the case of
the Prospectus, such Prospectus will not contain any 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, in light of the circumstances under
which they were made, not misleading;

                                     - 10 -
<PAGE>   12
                  (d) Use its reasonable best efforts to avoid the issuance of,
or, if issued, obtain the withdrawal of any stop order or order enjoining or
suspending the use or effectiveness of a Registration Statement or the lifting
of any suspension of the qualification (or exemption from qualification) of any
of the Transfer Restricted Securities for sale in any jurisdiction, at the
earliest practicable moment;

                  (e) If requested by the Special Counsel, the managing
underwriters, if any, or the Holders of a majority in aggregate principal amount
of the Transfer Restricted Securities being sold in connection with such
offering, (i) promptly include in a Prospectus supplement or post-effective
amendment such information as the Special Counsel, the managing underwriters, if
any, and such Holders agree should, in their reasonable judgment, be included
therein, and (ii) make all required filings of such Prospectus supplement or
such post-effective amendment as soon as reasonably practicable after the
Company has received notification of the matters to be included in such
Prospectus supplement or post-effective amendment; provided, however, that the
Company shall not be required to take any action pursuant to this Section 4(e)
that would, in the opinion of counsel for the Company, violate applicable law or
which is not reasonably required to comply with applicable securities laws;

                  (f) Furnish to each Holder who so requests, Special Counsel
and each managing underwriter, if any, without charge, at least one conformed
copy of each Registration Statement and each amendment thereto, including
financial statements (but excluding schedules, all documents incorporated or
deemed to be incorporated therein by reference and all exhibits, unless
requested in writing by such Holder, Special Counsel or managing underwriter);

                  (g) Deliver to each Holder, the Special Counsel, and the
underwriters, if any, without charge, as many copies of the Prospectus or
Prospectuses (including each form of Prospectus) and each amendment or
supplement thereto as such persons may reasonably request; and, unless the
Company shall have given notice to such Holder pursuant to Section 4(c), the
Company hereby consents to the use of such Prospectus and each amendment or
supplement thereto by each of the selling Holders of Transfer Restricted
Securities and the underwriters, if any, in connection with the offering and
sale of the Transfer Restricted Securities covered by such Prospectus and any
amendment or supplement thereto, provided, however, that no Holder shall be
entitled to use the Prospectus unless and until such Holder shall have furnished
to the Company any and all Requisite Information pursuant to Section 2(c)
hereof;

                  (h) Use its reasonable best efforts to register or qualify, or
cooperate with the Holders of Transfer Restricted Securities to be sold or
tendered for, the underwriters, if any, and their respective counsel in
connection with the registration or qualification (or exemption from such
registration or qualification) of, such Transfer Restricted Securities for offer
and sale under the securities or Blue Sky laws of such jurisdictions or such
other applicable governmental agencies or authorities within the United States
as any Holder or underwriter reasonably requests in writing, keep each such
registration or qualification (or exemption therefrom) effective during the
period such Registration Statement is required to be kept effective and do any
and all other acts or things necessary legally to enable the disposition in such
jurisdictions of the Transfer Restricted Securities covered by the applicable
Registration Statement; provided, however, that

                                     - 11 -
<PAGE>   13
the Company shall not be required to qualify generally to do business in any
jurisdiction where it is not then so qualified, take any action that would
subject it to general service of process in any such jurisdiction where it is
not then so subject or subject the Company to any tax in any such jurisdiction
where it is not then so subject;

                  (i) In connection with any sale or transfer of Transfer
Restricted Securities that will result in such securities no longer being
Transfer Restricted Securities, cooperate with the Holders and the managing
underwriters, if any, to (A) facilitate the timely preparation and delivery of
certificates representing Transfer Restricted Securities to be sold, which
certificates shall not bear any restrictive legends, for the Notes shall bear a
CUSIP number different from the CUSIP number for the Transfer Restricted
Securities and for any Transfer Restricted Securities shall be in a form
eligible for deposit with The Depository Trust Company and (B) enable such
Transfer Restricted Securities to be in such denominations and registered in
such names as the managing underwriters, if any, or Holders may reasonably
request at least two Business Days prior to any sale of Transfer Restricted
Securities;

                  (j)      [Intentionally Omitted.]

                  (k) Upon the occurrence of any event contemplated by Section
4(c)(vi) hereof, as promptly as reasonably practicable, prepare a supplement or
amendment, including, if appropriate, a post-effective amendment, to each
Registration Statement or a supplement to the related Prospectus or any document
incorporated or deemed to be incorporated therein by reference, and file any
other required document so that, as thereafter delivered, such Prospectus will
not contain an untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading;

                  (l) Prior to the effective date of the first Registration
Statement relating to the Transfer Restricted Securities, to provide a CUSIP
number for the Transfer Restricted Securities to be sold pursuant to the
Registration Statement;

                  (m) Enter into such agreements (including an underwriting
agreement in form, scope and substance as are customary in underwritten
offerings) reasonably satisfactory to the Company and take all such other
reasonable actions in connection therewith (including those reasonably requested
by the managing underwriters, if any, or the Holders of a majority in aggregate
principal amount of the Transfer Restricted Securities being sold) in order to
expedite or facilitate the sale of such Transfer Restricted Securities;
provided, however, that the Company is required to facilitate no more than two
underwritten offerings. In such connection, whether or not an underwriting
agreement is entered into and whether or not the registration is an underwritten
registration, (i) make such representations and warranties to the Holders of
such Transfer Restricted Securities and the underwriters, if any, with respect
to the business of the Company and its subsidiaries (including with respect to
businesses or assets acquired or to be acquired by any of them), and the
Registration Statement, Prospectus and documents, if any, incorporated or deemed
to be incorporated by reference therein, in each case, in form, substance and
scope as are customarily made by issuers to underwriters in underwritten
offerings and

                                     - 12 -
<PAGE>   14
reasonably acceptable to the Company, and confirm the same if and when
requested; (ii) seek to obtain opinions of counsel to the Company and updates
thereof (which counsel and opinions (in form, scope and substance) shall be
reasonably satisfactory to the managing underwriters, if any, and Special
Counsel to the Holders of the Transfer Restricted Securities being sold,
addressed to each selling Holder of Transfer Restricted Securities and each of
the underwriters, if any, covering the matters customarily covered in opinions
requested in underwritten offerings (including any such matters as may be
reasonably requested by such Special Counsel and underwriters); (iii) use all
reasonable efforts to obtain customary "cold comfort" letters and updates
thereof from the independent certified public accountants of the Company (and,
if necessary, any other independent certified public accountants of any
subsidiary of the Company or of any business acquired by the Company for which
financial statements and financial data is, or is required to be, included in
the Registration Statement), addressed (where reasonably possible) to each
selling Holder of Transfer Restricted Securities and each of the underwriters,
if any, such letters to be in customary form and covering matters of the type
customarily covered in "cold comfort" letters in connection with underwritten
offerings; (iv) if an underwriting agreement is entered into, the same shall
contain indemnification provisions and procedures no less favorable to the
selling Holders of Transfer Restricted Securities and the underwriters, if any,
than those set forth in Section 6 hereof (or such other provisions and
procedures acceptable to Holders of a majority in aggregate principal amount of
the Transfer Restricted Securities covered by such Registration Statement, the
managing underwriters and to the Company); and (v) deliver such documents and
certificates as may be reasonably requested by the Holders of majority in
aggregate principal amount of the Transfer Restricted Securities being sold,
their Special Counsel or the managing underwriters, if any, to evidence the
continued validity of the representations and warranties made pursuant to clause
(i) of this Section 4(m) and to evidence compliance with any customary
conditions contained in the underwriting agreement or other agreement entered
into by the Company;

                  (n) Make available for inspection by a representative of the
Holders of Transfer Restricted Securities being sold, any underwriter
participating in any such disposition of Transfer Restricted Securities, if any,
and any attorney, consultant or accountant retained by such selling Holders or
underwriter, at the offices where normally kept, during reasonable business
hours, all financial and other records, pertinent corporate documents and
properties of the Company and its subsidiaries as they may reasonably request,
and cause the officers, directors, agents and employees of the Company and its
subsidiaries to supply all information in each case reasonably requested by any
such representative, underwriter, attorney, consultant or accountant in
connection with such Registration Statement, provided, however, that such
persons shall first agree in writing with the Company that any information that
is reasonably and in good faith designated by the Company in writing as
confidential at the time of delivery or inspection (as the case may be) of such
information shall be kept confidential by such persons, unless (i) disclosure of
such information is required by court or administrative order or is necessary to
respond to inquiries of regulatory authorities, (ii) disclosure of such
information is required by law (including any disclosure requirements pursuant
to Federal securities laws in connection with the filing of any Registration
Statement or the use of any Prospectus), (iii) such information becomes
generally available to the public other than as a result of a disclosure or
failure to safeguard by

                                     - 13 -
<PAGE>   15
any such person or (iv) such information becomes available to any such person
from a source other than the Company and such source is not bound by a
confidentiality agreement.

                  (o) Use its reasonable best efforts to cause the Indenture to
be qualified under the TIA not later than the effective date of the first
Registration Statement relating to the Transfer Restricted Securities; and in
connection therewith, cooperate with the Trustee and the Holders of Notes
constituting Transfer Restricted Securities to effect such changes to the
Indenture, if any, as may be required for such Indenture to be so qualified in
accordance with the terms of the TIA; and execute, and use its best efforts to
cause the Trustee to execute, all customary documents as may be required to
effect such changes, and all other forms and documents (including Form T-1)
required to be filed with the SEC to enable the Indenture to be so qualified
under the TIA in a timely manner.

                  (p) Comply with applicable rules and regulations of the SEC
and make generally available to its security holders earning statements
satisfying the provisions of Section 11(a) of the Securities Act or Rule 158 of
the Securities Act (or any similar rule promulgated under the Securities Act),
no later than 45 days after the end of any 12-month period (or 90 days after the
end of any 12-month period if such period is a fiscal year) (i) commencing at
the end of any fiscal quarter in which Transfer Restricted Securities are sold
to underwriters in a firm commitment or best efforts underwritten offering and
(ii) if not sold to underwriters in such an offering, commencing on the first
day of the first fiscal quarter after the effective date of a Registration
Statement, which statement shall cover said period, consistent with the
requirements of Rule 158 of the Securities Act; and

                  (q) (i) list all shares of Common Stock covered by such
Registration Statement on any securities exchange on which the Common Stock is
then listed or (ii) if required by the applicable rules, authorize for quotation
on the National Association of Securities Dealers Automated Quotation System
("Nasdaq") or the National Market of Nasdaq all Common Stock covered by such
Registration Statement if the Common Stock is then so authorized for quotation.

         5.       Registration Expenses.

                  (a) All fees and expenses incident to the performance of or
compliance with this Agreement by the Company shall be borne by it whether or
not any Registration Statement is filed or becomes effective and whether or not
any securities are offered or sold pursuant to any Registration Statement. The
fees and expenses referred to in the foregoing sentence shall include, without
limitation, (i) all registration and filings fees (including, without
limitation, fees and expenses (A) with respect to filings required to be made
with the National Association of Securities Dealers, Inc. and (B) in compliance
with securities or Blue Sky laws (including, without limitation and in addition
to that provided for in (b) below, reasonable fees and disbursements of counsel
for the underwriters or the Special Counsel in connection with Blue Sky
qualifications of the Transfer Restricted Securities and determination of the
eligibility of the Transfer Restricted Securities for investment under the laws
of such jurisdictions as the managing underwriters, if any, or Holders of a
majority in aggregate principal amount of

                                     - 14 -
<PAGE>   16
Transfer Restricted Securities, may designate)), (ii) printing expenses
(including, without limitation, expenses of printing certificates for Transfer
Restricted Securities in a form eligible for deposit with The Depository Trust
Company and of printing Prospectuses if the printing of Prospectuses is required
by the managing underwriters, if any, or by the Holders of a majority in
aggregate principal amount of the Transfer Restricted Securities included),
(iii) messenger, telephone and delivery expenses of the Company, (iv) reasonable
fees and disbursements of counsel for the Company and the Special Counsel (plus
any local counsel deemed appropriate by the Holders of a majority in aggregate
principal amount of the Transfer Restricted Securities) in accordance with the
provisions of Section 5(b) hereof, (v) fees and disbursements of all independent
certified public accountants referred to in Section 4(m)(iii) (including,
without limitation, the expenses of any special audit and "comfort" letters
required by or incident to such performance), (vi) Securities Act liability
insurance, if the Company so desires such insurance, and (vii) fees and expenses
of all other persons retained by the Company. In addition, the Company shall pay
its internal expenses (including, without limitation, all salaries and expenses
of its officers and employees performing legal or accounting duties), the
expense of an annual audit and the fees and expenses incurred in connection with
the listing of the securities to be registered on any securities exchange or the
Nasdaq National Market. Notwithstanding anything in this Agreement to the
contrary, each Holder shall pay all underwriting discounts and brokerage
commissions with respect to any Transfer Restricted Securities sold by it.

                  (b) In connection with any registration hereunder, the Company
shall reimburse the Holders of the Transfer Restricted Securities being
registered or tendered for in such registration for the reasonable fees and
disbursements of not more than one firm of attorneys representing the selling
Holders (in addition to any local counsel), which firm shall initially be chosen
by the Holders of a majority in aggregate principal amount of the Transfer
Restricted Securities. Testa, Hurwitz & Thibeault, LLP shall be Special Counsel
for all purposes hereof, but which may, with the written consent of the
Purchasers (which shall not be unreasonably withheld), be another nationally
recognized law firm experienced in securities law matters designated by the
Company unless and until another Special Counsel shall have been selected by a
majority in aggregate principal amount of the Transfer Restricted Securities and
notice hereof shall have been given to the Company.

         6.       Indemnification.

                  (a) The Company agrees to indemnify and hold harmless (i) the
Purchasers, (ii) each Holder, (iii) each person, if any, who controls (within
the meaning of Section 15 of the Securities Act or Section 20 of the Exchange
Act) any of the foregoing (any of the persons referred to in this clause (iii)
being hereinafter referred to as a "controlling person"), and (iv) the
respective officers, directors, partners, employees, representatives and agents
of the Purchasers, the Holders (including predecessor Holders), or any
controlling person (any person referred to in clause (i), (ii), (iii) or (iv)
may hereinafter be referred to as an "Indemnified Person"), from and against any
and all losses, claims, damages, liabilities, expenses and judgments caused by
any untrue statement or alleged untrue statement of a material fact contained in
any Registration Statement or Prospectus or in any amendment or supplement
thereto or in any preliminary Prospectus, or caused by any omission or alleged
omission to state therein a material fact

                                     - 15 -
<PAGE>   17
required to be stated therein or necessary to make the statements therein (in
the case of any Prospectus or supplement thereto, in light of the circumstances
under which they were made) not misleading, except insofar as such losses,
claims, damages, liabilities, expenses or judgments are caused by any such
untrue statement or omission or alleged untrue statement or omission based upon
information relating to any Indemnified Person furnished to the Company by or on
behalf of such Indemnified Person expressly for use therein; provided, however,
that the foregoing indemnity with respect to any preliminary Prospectus shall
not inure to the benefit of any Indemnified Person from whom the person
asserting such losses, claims, damages, liabilities, expenses and judgments
purchased securities if such untrue statement or omission or alleged untrue
statement or omission made in such preliminary Prospectus is eliminated or
remedied in the Prospectus and a copy of the Prospectus shall not have been
furnished to such person in a timely manner due to the wrongful action or
wrongful inaction of such Indemnified Person, whether as a result of negligence
or otherwise.

                  (b) In case any action shall be brought against any
Indemnified Person, based upon any Registration Statement or any such Prospectus
or any amendment or supplement thereto and with respect to which indemnity may
be sought against the Company, such Indemnified Person shall promptly notify the
Company in writing and the Company shall assume the defense thereof, including
the employment of counsel reasonably satisfactory to such Indemnified Person and
payment of all fees and expenses. Any Indemnified Person shall have the right to
employ separate counsel in any such action and participate in the defense
thereof, but the fees and expenses of such counsel shall be at the expense of
such Indemnified Person, unless (i) the employment of such counsel shall have
been specifically authorized in writing by the Company, (ii) the Company shall
have failed to assume the defense and employ counsel or (iii) such Indemnified
Person or Persons shall have been advised by counsel that there may be a
conflict between the positions of the indemnifying party or parties and of the
indemnified party or parties in conducting the defense of such action or
proceeding or that there may be legal defenses available to such Indemnified
Person or Persons different from or in addition to those available to the
indemnifying party or parties (in which case the Company shall not have the
right to assume the defense of such action on behalf of such Indemnified
Person), it being understood, however, that the Company shall not, in connection
with any one such action or separate but substantially similar or related
actions in the same jurisdiction arising out of the same general allegations or
circumstances, be liable for the fees and expenses of more than one separate
firm of attorneys (in addition to any local counsel) for all such Indemnified
Persons, which firm shall be designated in writing by such Indemnified Persons,
and that all such fees and expenses shall be reimbursed as they are incurred.
The Company shall not be liable for any settlement of any such action effected
without its written consent but if settled with the written consent of the
Company, the Company agrees to indemnify and hold harmless, in accordance with
this Section 6, any Indemnified Person from and against any loss or liability by
reason of such settlement. No Indemnifying Party shall, without the prior
written consent of the Indemnified Party, effect any settlement of any pending
or threatened proceeding in respect of which any Indemnified Party is or could
have been a party and indemnity could have been sought hereunder by such
Indemnified Party, unless such settlement includes an unconditional release of
such Indemnified Party from all liability on claims that are the subject matter
of such proceeding.

                                     - 16 -
<PAGE>   18
                  (c) In connection with any Registration Statement pursuant to
which any Holder (or predecessor Holder) sold or offered for resale Transfer
Restricted Securities, such Holder (or predecessor Holder) agrees, severally and
not jointly, to indemnify and hold harmless the Company, its directors, its
officers, employees, representatives, agents and any person controlling the
Company within the meaning of Section 15 of the Securities Act or Section 20 of
the Exchange Act (any such person referred to as a "Company Indemnified Person"
and collectively with the Indemnified Persons, any such person referred to as an
"Indemnified Party"), to the same extent as the foregoing indemnity from the
Company to each Indemnified Person but only with reference to information
relating to such Indemnified Person furnished by or on behalf of such
Indemnified Person expressly for use in such Registration Statement. In case any
action shall be brought against any Company Indemnified Person, based on such
Registration Statement and in respect of which indemnity may be sought against
any Indemnifying Party, the Indemnifying Party shall have the rights and duties
given to the Company (except that if the Company shall have assumed the defense
thereof, such Indemnifying Party shall not be required to do so, but may employ
separate counsel therein and participate in defense thereof but the fees and
expenses of such counsel shall be at the expense of such Indemnifying Party),
and the Company Indemnified Person shall have the rights and duties given to the
Indemnified Person by Section 6(b) hereof.

                  (d) If the indemnification provided for in this Section 6 is
unavailable to an Indemnified Party in respect of any losses, claims, damages,
liabilities, expenses or judgments referred to therein, then each Indemnifying
Party, in lieu of indemnifying such Indemnified Party, shall contribute to the
amount paid or payable by such Indemnified Party as a result of such losses,
claims, damages, liabilities, expenses and judgments (i) in such proportion as
is appropriate to reflect the relative benefits received by the Company on the
one hand and each Indemnified Person on the other hand pursuant to the Purchase
Agreement or from the offering for resale of the Transfer Restricted Securities
or (ii) if the allocation provided by clause (i) above is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause (i) above but also the relative fault of
the Company and each such Indemnified Person in connection with the statements
or omissions which resulted in such losses, claims, damages, liabilities,
expenses or judgments, as well as any other relevant equitable considerations.
The relative fault of the Company and each such Indemnified Person shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission to state a material fact
relates to information supplied by the Company or such Indemnified Person and
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission.

                  The Company, the Holders and the Purchasers agree that it
would not be just and equitable if contribution pursuant to this Section 6(d)
were determined by pro rata allocation (even if the Indemnified Person were
treated as one entity for such purpose) or by any other method of allocation
which does not take account of the equitable considerations referred to in the
immediately preceding paragraph. The amount paid or payable by an Indemnified
Party as a result of the losses, claims, damages, liabilities, expenses or
judgments referred to in the immediately preceding paragraph shall be deemed to
include, subject to the limitations set forth above, any legal or other expenses
reasonably incurred by such Indemnified Party in connection

                                     - 17 -
<PAGE>   19
with investigating or defending any such action or claim. Notwithstanding the
provisions of this Section 6, no Indemnified Person shall be required to
contribute any amount in excess of the amount by which the total net profit
received by it in connection with the sale of the Transfer Restricted Securities
pursuant to this Agreement exceeds the amount of any damages which such
Indemnified Person has otherwise been required to pay by reason of such untrue
or alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. The Indemnified Persons'
obligations to contribute pursuant to this Section 6(d) are several in
proportion to the respective amount of Transfer Restricted Securities included
in and sold pursuant to any such Registration Statement by each Indemnified
Person and not joint.

         7.       Rules 144 and 144A.

                  The Company shall file the reports required to be filed by it
under the Securities Act and the Exchange Act in a timely manner and, if at any
time it is not required to file such reports but in the past had been required
to or did file such reports, it will, upon the request of any Holder, make
available other information as required by, and so long as necessary to permit
sales of, its Transfer Restricted Securities pursuant to Rule 144 and Rule 144A.
Notwithstanding the foregoing, nothing in this Section 7 shall be deemed to
require the Company to register any of its securities pursuant to the Exchange
Act.

         8.       Underwritten Registrations.

                  If any of the Transfer Restricted Securities covered by the
Shelf Registration Statement are to be sold in an underwritten offering, the
investment banker or investment bankers and manager or managers that will
administer the offering will be investment bankers of recognized national
standing selected by the Holders of a majority in aggregate principal amount of
such the Notes (or the proportional amount of Common Stock held as Transfer
Restricted Securities) included in such offering, subject to the consent of the
Company (which will not be unreasonably withheld or delayed).

                  No person may participate in any underwritten registration
hereunder unless such person (i) agrees to sell such person's Transfer
Restricted Securities on the basis reasonably provided in any underwriting
arrangements approved by the persons entitled hereunder to approve such
arrangements and (ii) completes and executes all questionnaires, powers of
attorney, indemnities underwriting agreements, lock-up agreements and other
documents reasonably required under the terms of such underwriting arrangements.

         9.       Miscellaneous.

                  (a) Remedies. In the event of a breach by the Company or by a
Holder of any of their respective obligations under this Agreement, each Holder
or the Company, in addition to being entitled to exercise all rights granted by
law, including, without limitation, recovery of damages, will be entitled to
specific performance of its rights under this Agreement. The Company and each
Holder agree that monetary damages would not be adequate compensation

                                     - 18 -
<PAGE>   20
for any loss incurred by reason of a breach by it of any of the provisions of
this Agreement and hereby further agree that, in the event of any action for
specific performance in respect of such breach, they shall waive the defense
that a remedy at law would be adequate. This Section 9(a) shall not apply to
Section 3.

                  (b) No Inconsistent Agreements. The Company shall not enter
into any agreement with respect to its securities that is inconsistent with the
rights granted to the Holders in this Agreement or otherwise conflicts with the
provisions hereof. The Company is not currently a party to any agreement
granting any registration rights with respect to any of its securities to any
person which conflicts with the Company's obligations hereunder or gives any
other party the right to include any securities in any Registration Statement
filed pursuant hereto, except for such rights and conflicts as have been
irrevocably waived. Without limiting the generality of the foregoing until the
date at which the Securities (as defined in the Purchase Agreement) cease to be
Transfer Restricted Securities, without the written consent of the Holders of a
majority in aggregate principal amount of the Transfer Restricted Securities,
the Company shall not grant to any person the right to request it to register
any of its securities under the Securities Act unless the rights so granted are
subject in all respect to the prior rights of the Holders set forth herein, and
are not otherwise in conflict or inconsistent with the provisions of this
Agreement.

                  (c) No Adverse Action Affecting the Transfer Restricted
Securities. The Company will not take any action with respect to the Transfer
Restricted Securities which would adversely affect the ability of any of the
Holders to include such Transfer Restricted Securities in a registration
undertaken pursuant to this Agreement.

                  (d) No Piggyback on Registrations. After the date hereof, the
Company shall not grant to any of its security holders (other than the Holders
in such capacity) the right to include any of its securities in the Shelf
Registration Statement.

                  (e) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof,
may not be given, without the written consent of the Holders of a majority in
aggregate principal amount of the Transfer Restricted Securities; provided,
however, that, for the purposes of this Agreement, Transfer Restricted
Securities that are owned, directly or indirectly, by either the Company or an
Affiliate of the Company are not deemed outstanding. Notwithstanding the
foregoing, a waiver or consent to depart from the provisions hereof with respect
to a matter that relates exclusively to the rights of Holders whose Transfer
Restricted Securities are being sold pursuant to an underwritten offering and
that does not directly or indirectly affect the rights of other Holders may be
given by Holders of a majority in aggregate principal amount of the Transfer
Restricted Securities being sold by such Holders pursuant to such an
underwritten offering; provided, however, that the provisions of this sentence
may not be amended, modified, or supplemented except in accordance with the
provisions of the immediately preceding sentence.

entered into by and among Clear Channel Communications, Inc., a Texas
corporation ("Parent"), CCU II Merger Sub, Inc., a Delaware corporation and a
wholly owned subsidiary of Parent ("Merger Sub"), and SFX Entertainment, Inc., a
Delaware corporation (the "Company").

                              W I T N E S S E T H:

            WHEREAS, the respective Boards of Directors of Parent and Merger Sub
and the Company have approved the combination of the Company and Parent upon the
terms and subject to the conditions set forth in this Agreement and Plan of
Merger, including, without limitation, the exhibits attached hereto
(collectively, this "Agreement");

            WHEREAS, the respective Boards of Directors of Parent and Merger Sub
and the Company have determined that it is advisable and in the best interests
of their respective shareholders for the Merger Sub to merge with and into
Company as set forth below (the "Merger") upon the terms and subject to the

share of Class A common stock, par value $.01 per share, of the Company

Company Common Stock or any shares of capital stock of Merger Sub, each share of

Stock in accordance with this Section 2.3 and the amount in cash to be paid in
lieu of fractional shares in accordance with Section 2.4(f)(ii) are collectively
referred to as the "Merger Consideration". As of the Effective Time, all shares

    Section 2.4 Exchange of Certificates.

         (a) Exchange Agent. Promptly after the Effective Time, Parent shall
deliver to a bank or trust company designated by Parent and reasonably
satisfactory to the Company (the "Exchange Agent"), for the benefit of the
holders of shares of Company Common Stock, for exchange in accordance with this
Article 2, through the Exchange Agent, certificates evidencing such number of
shares of Parent Common Stock issuable to holders of Company Common Stock in the
Merger pursuant to Section 2.3 and cash in an amount required to be paid
pursuant to Section 2.4(d) and 2.4(f) (such certificates for shares of Parent
Common Stock, together with any dividends or distributions with respect thereto
and cash, being hereinafter referred to as the "Exchange Fund"). The Exchange
Agent shall, pursuant to irrevocable instructions, deliver, out of the Exchange
Fund, to holders of Company Common Stock, Parent Common Stock contemplated to be
issued pursuant to Section 2.3 (and any dividends or other distributions to
which such holders are entitled pursuant to Section 2.4(d)) and the cash in lieu
of fractional shares of Parent Common Stock to which such holders are entitled
to pursuant to Section 2.4(f) hereof, out of the Exchange Fund. Except as
contemplated by Section 2.4(g) hereof, the Exchange Fund shall not be used for
any other purpose.

         (b) Exchange Procedures. As promptly as practicable after the Effective
Time, Parent shall cause the Exchange Agent to mail to each holder of a
certificate or certificates (the "Certificates") which immediately prior to the
Effective Time represented outstanding shares of Company Common Stock (other
than shares cancelled in accordance with Section 2.2 (the "Cancelled Shares"))
(i) a letter of transmittal (which shall be in customary form and shall specify
that delivery shall be effected, and risk of loss and title to the Certificates
shall pass, only upon proper delivery of the Certificates to the Exchange Agent)
and (ii) instructions for use in effecting the surrender of the Certificates in
exchange for certificates evidencing shares of Parent Common Stock, or cash in
lieu of fractional shares of Parent Common Stock to which such holder is
entitled pursuant to Section 2.4(f) hereof.

         (c) Exchange of Certificates. Upon surrender to the Exchange Agent of a
Certificate for cancellation, together with a letter of transmittal, duly
executed and completed in accordance with the instructions thereto, and such
other documents as may be reasonably required pursuant to such instructions, the
holder of such Certificate shall be entitled to receive in

                                       4
<PAGE>

exchange therefor a certificate representing that number of whole shares of
Parent Common Stock which such holder's shares of Company Common Stock shall
have been converted into pursuant to this Article 2 (and any cash in lieu of any
fractional shares of Parent Common Stock to which such holder is entitled
pursuant to Section 2.4(f) and any dividends or other distributions to which
such holder is entitled pursuant to Section 2.4(d)), and the Certificate so
surrendered shall forthwith be canceled. In the event of a transfer of ownership
of shares of Company Common Stock which is not registered in the transfer
records of the Company, shares of Parent Common Stock, cash in lieu of any
fractional shares of Parent Common Stock to which such holder is entitled
pursuant to Section 2.4(f) and any dividends or other distributions to which
such holder is entitled pursuant to Section 2.4(d) may be issued to a transferee
if the Certificate representing such shares of Company Common Stock is presented
to the Exchange Agent, accompanied by all documents required to evidence and
effect such transfer and by evidence that any applicable stock transfer taxes
have been paid. Until surrendered as contemplated by this Section 2.4, each
Certificate shall be deemed at all times after the Effective Time to represent
only the right to receive upon such surrender the number of whole shares of
Parent Common Stock into which the shares of Company Common Stock formerly
represented thereby have been converted, cash in lieu of any fractional shares
of Parent Common Stock to which such holder is entitled pursuant to Section
2.4(f) and any dividends or other distributions to which such holder is entitled
pursuant to Section 2.4(d).

         (d) Distributions with Respect to Unexchanged Shares of Parent Common
Stock. No dividends or other distributions declared or made after the Effective
Time with respect to Parent Common Stock with a record date after the Effective
Time shall be paid to the holder of any unsurrendered Certificate with respect
to the shares of Parent Common Stock represented thereby, and no cash payment in
lieu of any fractional shares shall be paid to any such holder pursuant to
Section 2.4(f), until the holder of such Certificate shall surrender such
Certificate. Subject to the effect of escheat, tax or other applicable laws,
following surrender of any such Certificate, there shall be paid promptly to the
holder of such Certificate representing whole shares of Parent Common Stock
issued in exchange therefor, without interest, (i) the amount of dividends and
other distributions with a record date after the Effective Time and theretofore
paid with respect to such whole shares of Parent Common Stock, (ii) at the
appropriate payment date, the amount of dividends and other distributions, with
a record date after the Effective Time but prior to surrender and a payment date
occurring after surrender, payable with respect to such whole shares of Parent
Common Stock and (iii) the amount of any cash payable with respect to a
fractional share of Parent Common Stock to which such holder is entitled
pursuant to Section 2.4(f).

         (e) No Further Rights in Company Common Stock. All shares of Parent
Common Stock into which the shares of Company Common Stock shall be converted in
accordance with the terms hereof (including any cash paid pursuant to Section
2.4(d) or 2.4(f)) shall be deemed to have been issued in full satisfaction of
all rights pertaining to such shares of Company Common Stock.

         (f) No Fractional Shares.

              (i) No certificates or scrip representing fractional shares of
Parent

                                       5
<PAGE>

Common Stock shall be issued upon the surrender for exchange of Certificates, no
dividend or distribution of Parent shall relate to such fractional share
interests and such fractional share interests will not entitle the owner thereof
to vote or to any rights of a stockholder of Parent.

              (ii) In lieu of the issuance of fractional shares, each holder of
Company Common Stock shall be entitled to receive an amount in cash equal to the
product obtained by multiplying (A) the fractional share interest to which such
holder (after taking into account all shares of Company Common Stock held at the
Effective Time by such holder) would otherwise be entitled by (B) the closing
price for a share of Parent Common Stock as reported on the New York Stock
Exchange ("NYSE") Composite Transaction Tape (as reported in The Wall Street
Journal or, if not reported thereby, any other authoritative source) on the last
trading day prior to the Closing Date.

         (g) Termination of Exchange Fund. Any portion of the Exchange Fund
(including any shares of Parent Common Stock) which remains undistributed to the
holders of Company Common Stock for six months after the Effective Time shall be
delivered to Parent, upon demand, and any holders of Company Common Stock who
have not theretofore complied with this Article 2 shall thereafter look only to
Parent for, and Parent shall deliver, the applicable Merger Consideration, any
cash in lieu of fractional shares of Parent Common Stock to which they are
entitled pursuant to Section 2.4(f) and any dividends or other distributions
with respect to Parent Common Stock to which they are entitled pursuant to
Section 2.4(d). Any portion of the Exchange Fund remaining unclaimed by holders
of shares of Company Common Stock as of a date which is immediately prior to
such time as such amounts would otherwise escheat to or become property of any
government entity shall, to the extent permitted by applicable law, become the
property of Parent free and clear of any claims or interest of any Person
previously entitled thereto.

         (h) No Liability. None of the Exchange Agent, Parent nor the Surviving
Corporation shall be liable to any holder of shares of Company Common Stock for
any such shares of Parent Common Stock (or dividends or distributions with
respect thereto) or cash delivered to a public official pursuant to any
abandoned property, escheat or similar law.

         (i) Withholding Rights. Each of the Surviving Corporation and the
Exchange Agent shall be entitled to deduct and withhold from the consideration
otherwise payable pursuant to this Agreement to any holder of shares of Company
Common Stock such amounts as it is required to deduct and withhold with respect
to the making of such payment under the Code, or any provision of state, local
or foreign tax law. To the extent that amounts are so properly withheld by the
Surviving Corporation or the Exchange Agent, as the case may be, such withheld
amounts shall be treated for all purposes of this Agreement as having been paid
to the holder of the shares of Company Common Stock, in respect of which such
deduction and withholding was made by the Surviving Corporation or the Exchange
Agent, as the case may be.

         (j) Lost Certificates. If any Certificate shall have been lost, stolen
or destroyed, upon the making of an affidavit of that fact by the Person
claiming such Certificate to be lost, stolen or destroyed and, if required by
the Surviving Corporation, the posting by such Person of a bond, in such
reasonable amount as the Surviving Corporation may direct, as

                                       6
<PAGE>

indemnity against any claim that may be made against it with respect to such
Certificate, the Exchange Agent will issue in exchange for such lost, stolen or
destroyed Certificate the applicable Merger Consideration, any cash in lieu of
fractional shares of Parent Common Stock to which the holder thereof is entitled
pursuant to Section 2.4(f) and any dividends or other distributions to which the
holder thereof is entitled pursuant to Section 2.4(d).

         (k) Further Assurances. If, at any time after the Effective Time, the
Surviving Corporation shall consider or be advised that any deeds, bills of
sale, assignments, assurances or any other actions or things are necessary or
desirable to vest, perfect or confirm of record or otherwise in the Surviving
Corporation its right, title or interest in, to or under any of the rights,
properties or assets of either of the Merger Sub or the Company acquired or to
be acquired by the Surviving Corporation as a result of, or in connection with,
the Merger or otherwise to carry out this Agreement, the officers of the
Surviving Corporation shall be authorized to execute and deliver, in the name
and on behalf of each of the Merger Sub and the Company or otherwise, all such
deeds, bills of sale, assignments and assurances and to take and do, in such
names and on such behalves or otherwise, all such other actions and things as
may be necessary or desirable to vest, perfect or confirm any and all right,
title and interest in, to and under such rights, properties or assets in the
Surviving Corporation or otherwise to carry out the purposes of this Agreement.

    Section 2.5 Stock Transfer Books. At the Effective Time, the stock transfer
books of the Company shall be closed and there shall be no further registration
of transfers of shares of Company Common Stock thereafter on the records of the
Company. From and after the Effective Time, the holders of Certificates
representing shares of Company Common Stock outstanding immediately prior to the
Effective Time shall cease to have any rights with respect to such shares of
Company Common Stock, except as otherwise provided herein or by law. On or after
the Effective Time, any Certificates presented to the Exchange Agent (or Parent
for any reason) shall promptly be exchanged for certificates representing shares
of Parent Common Stock, any cash in lieu of fractional shares of Parent Common
Stock to which the holders thereof are entitled pursuant to Section 2.4(f) and
any dividends or other distributions to which the holders thereof are entitled
pursuant to Section 2.4(d).

audited consolidated financial statements and unaudited consolidated interim
financial statements included in the Company SEC Reports (including any related
notes and schedules) fairly present in all material respects the financial
position of the Company and its consolidated Subsidiaries as of the dates
thereof and their results of operations and cash flows for the periods then
ended (subject, where appropriate, to normal year-end adjustments), in each case
in accordance with past practice and generally accepted accounting principles in
the United States ("GAAP") consistently applied during the periods involved
(except as otherwise disclosed in the notes thereto and except that the
unaudited financial statements therein do not contain all of the footnote
disclosures required by GAAP). Since April 27, 1998, the Company has timely
filed all material reports, registration statements and other filings required
to be filed by it with the SEC under the rules and regulations of the SEC.

    Section 3.5 No Undisclosed Liabilities. As of the date of this Agreement,
neither the Company nor any of its Subsidiaries has any liabilities or
obligations of any nature, whether or not accrued, contingent or otherwise, of a
type required by GAAP to be reflected on a consolidated balance sheet except (a)
liabilities or obligations reflected in any of the Company SEC Reports, (b)
liabilities or obligations incurred since September 30, 1999 in the ordinary
course of the Company's business and (c) liabilities or obligations which would
not in the aggregate reasonably be expected

                                       10
<PAGE>

to have a Material Adverse Effect on the Company.

    Section 3.6 No Violation of Law. The businesses of the Company and its
Subsidiaries are not being conducted in violation of any law, ordinance or
regulation of any governmental body or authority (provided that no
representation or warranty is made in this Section 3.6 with respect to
Environmental Laws (as defined in Section 3.7 below) which are dealt with
exclusively in Section 3.7) except (a) as described in any of the Company SEC
Reports and (b) for violations or possible violations which would not in the
aggregate reasonably be expected to have a Material Adverse Effect on the
Company. The Company and its Subsidiaries have all permits, licenses and
governmental authorizations material to ownership or occupancy of their
respective properties and assets and the carrying on of their respective
businesses, except for such permits, licenses and governmental authorizations
the failure of which to have would not reasonably be expected to have in the
aggregate a Material Adverse Effect on the Company.

    Section 3.7 Environmental Laws and Regulations. Except as described in any
of the Company SEC Reports, (a) to the Knowledge of the Company, the Company and
each of its Subsidiaries is in material compliance with all applicable federal,
state, local and foreign laws and regulations relating to pollution or
protection of human health or the environment (including, without limitation,
ambient air, surface water, ground water, land surface or subsurface strata)
(collectively, "Environmental Laws" ), except for noncompliance which would not
in the aggregate reasonably be expected to have a Material Adverse Effect on the
Company, which compliance includes, but is not limited to, the possession by the
Company and its Subsidiaries of material permits and other governmental
authorizations required under applicable Environmental Laws, and material
compliance with the terms and conditions thereof, (b) neither the Company nor
any of its Subsidiaries has received written notice of, or, to the Knowledge of
the Company, is the subject of, any actions, causes of action, claims,
investigations, demands or notices by any Person alleging liability under, or
non-compliance with, any Environmental Law or that the Company or any Subsidiary
is a potentially responsible party at any Superfund site or state equivalent
site ("Environmental Claims") which would in the aggregate reasonably be
expected to have a Material Adverse Effect on the Company, (c) to the Knowledge
of the Company, there are no circumstances that are reasonably likely to prevent
or interfere with such material compliance in the future, (d) to the Knowledge
of the Company, the Company and its Subsidiaries have not disposed of or
released hazardous materials (at a concentration or level which requires
remedial action under any Environmental Law) at any real property currently
owned or leased by the Company or any Subsidiary or at any other real property,
except for such disposals or releases as would not in the aggregate reasonably
be expected to have a Material Adverse Effect on the Company, and (e) neither
the Company nor its Subsidiaries have agreed to indemnify any predecessor or
other party with respect to any environmental liability, other than customary
indemnity provisions contained in agreements entered into in the ordinary course
of business and provisions which would not in the aggregate reasonably be
expected to have a Material Adverse Effect on the Company.

    Section 3.8 No Undisclosed Employee Benefit Plan Liabilities or Severance
Arrangements.

         (a) All benefit and compensation plans, contracts, policies, agreements
or other arrangements providing for compensation, severance, termination pay,
performance

                                       11
<PAGE>

awards, stock or stock related awards, fringe benefits, change in control,
employment agreement, deferred compensation or other employee benefits of any
kind, whether formal or informal, funded or unfunded, written or oral, or
arrangements covering current employees or former employees of the Company and
its Subsidiaries (all such current and former employees of the Company and its
Subsidiaries being herein referred to as the "Employees") and current or former
directors of the Company, including, but not limited to, "employee benefit
plans" within the meaning of Section 3(3) of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA") (the "Benefit Plans") are listed on
Section 3.8(a) of the Company Disclosure Letter, except for those plans,
contracts, policies or other arrangements that are not material to the Company
and its Subsidiaries, taken as a whole. There are no "change in control" or
similar provisions covering current employees of the Company or any of its
Subsidiaries, and, to the Knowledge of the Company, covering any former
employees of the Company or any of its Subsidiaries, other than those set forth
in the Benefit Plans identified on Section 3.8(a) of the Company Disclosure
Letter and except for such exceptions as would not in the aggregate reasonably
be expected to have a Material Adverse Effect on the Company.

         (b) All employee benefit plans within the meaning of Section 3(3) of
ERISA, other than "multiemployer plans" within the meaning of Section 3(37) of
ERISA, covering Employees (the "Plans"), to the extent subject to ERISA or the
Code, are in substantial compliance with ERISA, the Code, and all other
applicable law, except for such exceptions as would not in the aggregate
reasonably be expected to have a Material Adverse Effect on the Company. Each
Plan which is an "employee pension benefit plan" within the meaning of Section
3(2) of ERISA ("Pension Plan") and which is intended to be qualified under
Section 401(a) of the Code, has received a favorable determination letter from
the Internal Revenue Service, or operates as a standardized prototype plan, or
is operating within the remedial amendment period and may still obtain a
favorable determination letter from the Internal Revenue Service and, to the
Company's Knowledge, there exists no circumstances likely to result in
revocation of any such favorable determination letter, except, in each case, for
such exceptions as would not in the aggregate reasonably be expected to have a
Material Adverse Effect on the Company. There is no material pending or, to the
Knowledge of the Company, threatened litigation relating to the Plans except for
such litigation as would not in the aggregate reasonably be expected to have a
Material Adverse Effect on the Company. Except for such exceptions as would not
in the aggregate reasonably be expected to have a Material Adverse Effect on the
Company, neither the Company nor any of its Subsidiaries has engaged in a
transaction with respect to any Plan that, assuming the taxable period of such
transaction expired as of the date of this Agreement, could subject the Company
or any Subsidiary to a tax or penalty imposed by either Section 4975 of the Code
or Section 502(i) of ERISA in an amount which would be material.

         (c) No current or former Pension Plan of the Company or any of its
Subsidiaries, or any entity which is considered one employer with the Company
under Section 4001 of ERISA or Section 414 of the Code (an "ERISA Affiliate"),
is or has been subject to Title IV of ERISA or Section 412 of the Code within
the past six years, except for such exceptions as would not in the aggregate
reasonably be expected to have a Material Adverse Effect on the Company.

                                       12
<PAGE>

         (d) All contributions required to be made under the terms of any
Benefit Plan have been timely made or have been reflected on the audited
financial statements of the Company, except for such exceptions as would not in
the aggregate reasonably be expected to have a Material Adverse Effect on the
Company.

         (e) Neither the Company nor any of its Subsidiaries has any obligations
for retiree health and life benefits under any Benefit Plan, except for those
under collective bargaining agreements existing on the date of this Agreement
and such exceptions as would not in the aggregate reasonably be expected to have
a Material Adverse Effect on the Company.

         (f) Except for such exceptions as would not in the aggregate reasonably
be expected to have a Material Adverse Effect on the Company, the consummation
of the transactions contemplated by this Agreement will not, solely as a result
of such consummation, (i) entitle any Employees to severance pay, (ii)
accelerate the time of payment or vesting or trigger any payment or funding
(through a grantor trust or otherwise) of compensation or benefits under,
materially increase the amount payable or trigger any other material obligation
pursuant to, any of the Benefit Plans (other than the Company Stock Option Plans
and the options and warrants described in Section 3.2 of the Company Disclosure
Letter) or (iii) result in any breach or violation of, or a default under, any
of the Benefit Plans.

         (g) Any amount that could be received (whether in cash, property, or
vesting of property) as a result of the transactions contemplated by this
Agreement by any officer, director, employee or independent contractor of the
Company or any of its Subsidiaries, who is a "disqualified individual" (as
defined in proposed Treasury Regulation Section 1.280G-1), under any employment
arrangement or Benefit Plan would not be characterized as an "excess parachute
payment" (as defined in Section 280G of the Code) except for such exceptions as
would not in the aggregate reasonably be expected to have a Material Adverse
Effect on the Company.

         (h) All Benefit Plans covering current or former non-U.S. Employees
comply in all material respects with applicable law, except for such exceptions
as would not in the aggregate reasonably be expected to have a Material Adverse
Effect on the Company. No unfunded liabilities exist with respect to any Benefit
Plan that covers such non-U.S. Employees, except for such exceptions as would
not in the aggregate reasonably be expected to have a Material Adverse Effect on
the Company.

    Section 3.9 Absence of Certain Changes or Events. Other than as disclosed in
the Company SEC Reports or previously disclosed in writing to Parent, since
September 30, 1999 and to the date of this Agreement, the businesses of the
Company and its Subsidiaries have been conducted in all material respects in the
ordinary course and there has not been any event, occurrence, development or
state of circumstances or facts that has had a Material Adverse Effect on the
Company. Since September 30, 1999 and to the date of this Agreement, no
dividends or distributions have been declared or paid on or made with respect to
the shares of capital stock or other equity interests of the Company or its
Subsidiaries nor have any such shares been repurchased

                                       13
<PAGE>

or redeemed, other than dividends or distributions paid to the Company or a
wholly-owned Subsidiary and other than dividends, distributions, repurchases and
redemptions with respect to equity interests in Subsidiaries not exceeding $2.0
million in the aggregate.

    Section 3.10 Investigations; Litigation. Except as described in any of the
Company SEC Reports or previously disclosed in writing to Parent:

         (a) to the Knowledge of the Company, no investigation or review by any
governmental body or authority with respect to the Company or any of its
Subsidiaries which would in the aggregate reasonably be expected to have a
Material Adverse Effect on the Company is pending nor has any governmental body
or authority notified the Company in writing of an intention to conduct the
same; and

         (b) there are no actions, suits or proceedings pending (or, to the
Company's Knowledge, threatened) against or affecting the Company or its
Subsidiaries, or any of their respective properties or before any federal,
state, local or foreign governmental body or authority, which, in the aggregate,
are reasonably likely to have a Material Adverse Effect on the Company.

    Section 3.11 Proxy Statement; Registration Statement; Other Information. The
information, taken as a whole, with respect to the Company or its Subsidiaries
to be included in the Proxy Statement (as defined in Section 5.2) or the
Registration Statement (as defined in Section 5.2) will not, in the case of the
Proxy Statement or any amendments thereof or supplements thereto, at the time of
the mailing of the Proxy Statement or any amendments or supplements thereto, and
at the time of the Company Special Meeting (as defined in Section 5.3), or, in
the case of the Registration Statement, at the time it becomes effective or at
the effective time of any post-effective amendment, contain any untrue statement
of a material fact or omit to state any material fact required to be stated
therein or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading, except that no
representation is made by the Company with respect to information supplied in
writing by Parent, Merger Sub or any affiliate of Parent specifically for
inclusion in the Proxy Statement. The Proxy Statement (as it relates to the
Company) will comply as to form in all material respects with the provisions of
the Exchange Act and the rules and regulations promulgated thereunder.

    Section 3.12 Lack of Ownership of Parent Common Stock. Neither the Company
nor any of its Subsidiaries owns any shares of Parent Common Stock or other
securities convertible into shares of Parent Common Stock (exclusive of any
shares owned by the Company's Benefit Plans).

    Section 3.13 Tax Matters.

         (a) All federal, state, local and foreign Tax Returns required to be
filed by or on behalf of the Company, each of its Subsidiaries, and each
affiliated, combined, consolidated or unitary group of which the Company or any
of its Subsidiaries or was a member (a "Company Group") have been timely filed
or requests for extensions to file such returns or reports have been timely
filed and granted and have not expired, and all returns filed are complete and
accurate except to the extent any failure to file or any inaccuracies in filed
returns would not,

                                       14
<PAGE>

individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect on the Company. All Taxes due and owing by the Company, any
Subsidiary of the Company or any Company Group have been paid, or adequately
reserved for, except to the extent any failure to pay or reserve would not,
individually or in the aggregate reasonably be expected to have a Material
Adverse Effect on the Company. There is no audit examination, deficiency, refund
litigation, proposed adjustment or matter in controversy with respect to any
Taxes due and owing by the Company, any Subsidiary of the Company or any Company
Group nor has the Company or any Subsidiary filed any waiver of the statute of
limitations applicable to the assessment or collection of any Tax, in each case,
which would, individually or in the aggregate, reasonably be expected to have a
Material Adverse Effect on the Company. All assessments for Taxes due and owing
by the Company, any Subsidiary of the Company or any Company Group with respect

Neither the Company nor any Subsidiary is a party to any tax indemnity
agreement, tax sharing agreement or other agreement under which the Company or
any Subsidiary could become liable to another Person as a result of the
imposition of a Tax upon any Person, or the assessment or collection of a Tax,
except for such agreements as would not in the aggregate reasonably be expected
to have a Material Adverse Effect on the Company. The Company and each of its
Subsidiaries has complied in all material respects with all rules and
regulations relating to the withholding of Taxes, except to the extent any such
failure to comply would not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect on the Company.

         (b) Neither the Company nor any of its Subsidiaries has Knowledge of
any fact or has taken any action that could reasonably be expected to prevent
the Merger from qualifying as a reorganization within the meaning of Section
368(a) of the Code.

Subsidiaries.

in each jurisdiction in which the ownership of its properties or the conduct of
its business requires such qualification, except for jurisdictions in which such
failure to be so qualified or to be in good standing would not in the aggregate
reasonably be expected to have a Material Adverse Effect on Parent or Merger
Sub. The copies of Parent's Articles of Incorporation, as amended, and Amended
and Restated By-laws and Merger Sub's charter and by-laws which have been made
available to the Company are complete and correct and in full force and effect

rights, calls or rights or other arrangements or commitments obligating any

Merger. Each of Parent and the Company shall furnish all information concerning
it and the holders of its capital stock as the other may reasonably request in
connection with such actions and the preparation of the Registration Statement
and Proxy Statement. As promptly as practicable after the Registration Statement
shall have become effective, the Company shall mail the Proxy Statement to its
stockholders. The Proxy Statement shall include the recommendation of the Board
of Directors of the Company in favor of the Merger (subject to Section 5.10(d)
hereof) and the Charter Amendment.

         Subject to Section 5.10(d) hereof, no amendment or supplement to the
Proxy Statement or the Registration Statement will be made by Parent or the
Company without the approval of the other party (which approval shall not be
unreasonably withheld or delayed). Parent and the Company each will advise the
other, promptly after it receives notice thereof, of the time when the
Registration Statement has become effective or any supplement or amendment has
been filed, of the issuance of any stop order, the suspension of the
qualification of the Parent Common Stock issuable in connection with the Merger
for offering or sale in any jurisdiction, or any request by the SEC for
amendment of the Proxy Statement or the Registration Statement or comments
thereon and responses thereto or requests by the SEC for additional information.

         (b) The information supplied by Parent for inclusion in the
Registration Statement and the Proxy Statement shall not, at (1) the time the
Registration Statement is declared effective, (2) the time the Proxy Statement
(or any amendment thereof or supplement thereto) is first mailed to the
stockholders of the Company, (3) the time of the Company Special Meeting, and
(4) the Effective Time, contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary in order
to make the statements therein not misleading. If at any time prior to the
Effective Time any event or circumstance relating to Parent or any of its
Subsidiaries, or their respective officers or directors, should be discovered by
Parent which should be set forth in an amendment or a supplement to the
Registration Statement or Proxy Statement, Parent shall promptly inform the
Company. All documents that Parent is responsible for filing with the SEC in
connection with the transactions contemplated herein will comply as to form and
substance in all material respects with the

                                       29
<PAGE>

applicable requirements of the Securities Act and the rules and regulations
thereunder and the Exchange Act and the rules and regulations thereunder.

         (c) The information supplied by the Company for inclusion in the
Registration Statement and the Proxy Statement shall not, at (1) the time the
Registration Statement is declared effective, (2) the time the Proxy Statement
(or any amendment thereof or supplement thereto) is first mailed to the
stockholders of the Company, (3) the time of the Company Special Meeting, and
(4) the Effective Time, contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary in order
to make the statements therein not misleading. If at any time prior to the
Effective Time any event or circumstance relating to the Company or any of its
Subsidiaries, or their respective officers or directors, should be discovered by
the Company which should be set forth in an amendment or a supplement to the
Registration Statement or Proxy Statement, the Company shall promptly inform
Parent. All documents that the Company is responsible for filing with the SEC in
connection with the transactions contemplated herein will comply as to form and
substance in all material respects with the applicable requirements of the
Securities Act and the rules and regulations thereunder and the Exchange Act and
the rules and regulations thereunder.

    Section 5.3 Stockholders' Meeting. The Company shall, in accordance with
applicable law and its Amended and Restated Certificate of Incorporation and
By-laws duly call, give notice of, convene and hold a special meeting (which, as
may be duly adjourned, the "Company Special Meeting") of its stockholders for
the purpose of approving and adopting the agreement of merger (as such term is
used in Section 251 of the DGCL) set forth in this Agreement, approving the
Merger and approving the Charter Amendment, in each case by the holders of a
majority of the outstanding shares of Company Common Stock (with the holders of
Company Class A Common Stock and the holders of Company Class B Common Stock
voting together as a single class) and the affirmative vote of the holders of a
majority of the outstanding shares of each of the Company Class A Common Stock
and Company Class B Common Stock voting as separate classes (the "Company
Stockholder Approval"). The Company agrees to use its reasonable efforts to
cause the Company Special Meeting to occur within seventy-five (75) days after
the date on which the Registration Statement becomes effective, but not earlier
than twenty (20) business days after the date the Proxy Statement is first
mailed to stockholders. The Company shall include in the Proxy Statement the
recommendation of its Board of Directors ("Company Board Recommendation") that
its stockholders vote in favor of the Company Stockholder Approval, subject to
the duties of the Board of Directors of the Company to make any further
disclosure to the stockholders (which shall not, unless expressly stated,
constitute a withdrawal or adverse modification of such recommendation) and
subject to the right to withdraw, modify or change such recommendation in
accordance with Section 5.10 of this Agreement. If the Board of Directors of the
Company withdraws, modifies or changes its recommendation of this Agreement or
the Merger in a manner adverse to Parent or resolves to do any of the foregoing,
the Company shall nevertheless remain obligated to call, give notice of, convene
and hold the Company Special Meeting.

    Section 5.4 Approvals and Consents; Cooperation.

         (a) The Company and Parent shall together, or pursuant to an allocation
of responsibility to be agreed upon between them:

                                       30
<PAGE>

              (i) as soon as is reasonably practicable take all such action as
may be required under state blue sky or securities laws in connection with the
transactions contemplated by this Agreement;

              (ii) promptly prepare and file with the NYSE listing applications
covering the shares of Parent Common Stock issuable in the Merger or upon
exercise of the Company stock options, warrants, conversion rights or other
rights or vesting or payment of other Company equity based awards and use its
reasonable best efforts to obtain, prior to the Effective Time, approval for the
listing of such Parent Common Stock, subject only to official notice of
issuance;

              (iii) cooperate with one another in seeking any actions, consents,
approvals or waivers or making any filings in connection with the transactions
contemplated by this Agreement; and

              (iv) cooperate with one another in obtaining the opinions
described in Section 6.1(g) of this Agreement.

         (b) Subject to the limitations contained in Section 5.2, the Company
and Parent shall each furnish to one another and to one another's counsel all
such information as may be required in order to effect the foregoing actions.

    Section 5.5 Access to Information; Confidentiality. As permitted by law,
each of the Company and Parent shall, upon reasonable notice to an Executive
Officer (as defined in Section 8.2 hereof) of the Company or Parent, as the case
may be, afford to the other party, and to such party's authorized officers,
employees, accountants, counsel, financial advisors and other representatives
(collectively, "Representatives"), reasonable access during normal business
hours, in a manner so as not to interfere with the normal operations of the
Company or Parent and their respective Subsidiaries and subject to reasonable
restrictions imposed by an Executive Officer of the Company or Parent, as the
case may be, during the period prior to the Effective Time to all the
properties, books, contracts, commitments and records of the Company or Parent
and their respective Subsidiaries, and during such period, the Company or Parent
shall furnish promptly to the other party (a) a copy of each report, schedule,
registration statement and other document filed by it or its Subsidiaries during
such period pursuant to the requirements of applicable federal or state
securities laws and (b) all other information concerning its business,
properties and personnel as the other party may reasonably request.
Notwithstanding anything to the contrary in this Agreement, neither party nor
any or its Subsidiaries shall be required to disclose any information to the
other party or its authorized representatives if doing so would (i) violate any
federal, state, local or foreign law, rule or regulation to which such party or
any of its Subsidiaries is subject, (ii) violate the regulations or requirements
of the NYSE, (iii) violate the terms of any confidentiality agreement or similar
agreement or arrangement to which such party or any of its Subsidiaries is a
party (provided that such party shall use all reasonable efforts to cause the
counterparty thereto to waive such agreement) or (iv) directly or indirectly
affect either party's competitive position in any of the markets in which either
party operates or in respect of the activities in which either party is engaged.
No investigation or information furnished pursuant to this Section 5.5 shall
affect any representations or warranties made by the parties herein or the
conditions to the obligations of the

                                       31
<PAGE>

parties to consummate the Merger. Each party will, and will counsel its
Representatives to, keep such information provided to it by the other party
confidential in accordance with the terms of the Confidentiality Agreement,
dated February 18, 2000, between Parent and the Company (the "Confidentiality
Agreement") the terms of which are incorporated herein by reference, as if such
information were Confidential Information (as such term is defined in the
Confidentiality Agreement).

    Section 5.6 Affiliates. The Company shall, prior to the Effective Time,
deliver to Parent a list (reasonably satisfactory to counsel for Parent),
setting forth the names and addresses of all Persons who are, at the time of the
Company Special Meeting, in the Company's reasonable judgment, "affiliates" of
the Company for purposes of Rule 145 under the Securities Act. The Company shall
furnish such information and documents as Parent may reasonably request for the
purpose of reviewing such list. The Company will use its reasonable efforts to
cause its affiliates to deliver to Parent not later that 10 days prior to the
date of the Company Special Meeting, a written agreement substantially in the
form attached as Exhibit 5.6, with such modifications as may be appropriate, and
will use its reasonable efforts to cause Persons or entities who become
"affiliates" after such date but prior to the Closing Date to execute and
deliver these agreements at least 5 days prior to the Closing Date.

    Section 5.7 Rights Under Stock Plans.

         (a) Each outstanding option or warrant to purchase shares of Company
Common Stock ("Option") granted under the Company Stock Option Plans or
otherwise, which is outstanding immediately prior to the Effective Time, whether
or not then exercisable, shall vest in accordance with the terms of such Company
Stock Option Plan or agreement under which it was granted and shall be assumed
by Parent and deemed to constitute an option or warrant to acquire, on the same
terms and conditions, mutatis mutandis (including, without limitation
adjustments for any stock dividend, subdivision, reclassification,
recapitalization, split, combination, exchange of shares or similar
transaction), as were applicable under such Option or agreement prior to the
Effective Time, the number of shares of Parent Common Stock as the holder of
such Option would have been entitled to receive pursuant to the Merger had such
holder exercised such Option in full immediately prior to the Effective Time
(not taking into account whether or not such Option was in fact exercisable) at
a price per share equal to (x) the aggregate exercise price for Company Common
Stock purchasable pursuant to such Option divided by (y) the Class A Conversion
Number; provided, that the number of shares of Parent Common Stock that may be
purchased upon exercise of any such Option or agreement shall not include any
fractional share and, upon exercise of such Option or agreement, a cash payment
shall be made for any fractional share based upon the last sale price per share
of Parent Common Stock on the trading day immediately preceding the date of
exercise. From and after the Effective Time, Parent and the Surviving
Corporation shall comply with the terms of the Company Stock Option Plans and
the agreements governing any Options. The adjustments provided herein with
respect to any Options that are "incentive stock options" (as defined in Section
422 of the Code) shall be effected in a manner consistent with Section 424(a) of
the Code.

         (b) Parent shall cause to be taken all corporate action necessary to
reserve for

                                       32
<PAGE>

issuance a sufficient number of shares of Parent Common Stock for delivery upon
exercise of Options in accordance with this Section 5.7. As promptly as
practicable after the Effective Time, Parent shall use its reasonable efforts to
cause Parent Common Stock subject to assumed Options to be registered under the
Securities Act pursuant to a registration statement on Form S-8 (or any
successor or other appropriate forms) and shall use its reasonable efforts to
cause the effectiveness of such registration statement (and current status of
the prospectus or prospectuses contained therein) to occur promptly after the
Effective Time and to be maintained for so long as such Options remain
outstanding.

         (c) At the Effective Time, by virtue of the Merger and without any
action on the part of the holder of any stock appreciation right ("SAR"), each
outstanding SAR issued by the Company on or prior to the date of this Agreement
shall, as of the Effective Time, automatically and without any action on the
part of the holder thereof, be assumed by Parent. The holders of such SARs shall
continue to have, and be subject to, the same terms and conditions set forth in
the agreements pursuant to which the SARs were issued in effect immediately
prior to the Effective Time, except that (i) such SARs shall be exercisable for
cash representing that number of whole shares of Parent Common Stock equal to
the product of the number of shares of Class A Common Stock covered by the SAR
immediately prior to the Effective Time multiplied by the Class A Conversion
Number rounded up to the nearest whole number of shares of Parent Common Stock
and (ii) the per share strike price for the cash representing shares of Parent
Common Stock issuable upon the exercise of such assumed SAR shall be equal to
the quotient determined by dividing the strike price per share of Class A Common
Stock specified for such SAR under the applicable agreement immediately prior to
the Effective Time by the Class A Conversion Number, rounding the resulting
strike price down to the nearest whole cent. The holders of the SARs will be
entitled to receive only cash upon exercise of the SARs in lieu of Parent Common
Stock as such amount shall be determined in accordance with the agreements
pursuant to which the SARs were issued.

    Section 5.8 Filings; Other Action.

         (a) Subject to the terms and conditions herein provided, the Company
and Parent shall (i) promptly make their respective filings and thereafter make
any other required submissions under the HSR Act, and (ii) use reasonable
efforts to cooperate with one another in (A) determining whether any filings are
required to be made with, or consents, permits, authorizations or approvals are
required to be obtained from, any third party, the United States government or
any agencies, departments or instrumentalities thereof or other governmental or
regulatory bodies or authorities of federal, state, local and foreign
jurisdictions in connection with the execution and delivery of this Agreement
and the consummation of the transactions contemplated hereby and thereby and (B)
timely making all such filings and timely seeking all such consents, permits,
authorizations or approvals, and (iii) take, or cause to be taken, all other
actions and do, or cause to be done, all other things necessary, proper or
advisable to consummate and make effective the transactions contemplated hereby,
including, without limitation, taking or undertaking all such further action as
may be necessary to resolve such objections, if any, as the Federal Trade
Commission, the Antitrust Division of the Department of Justice, state antitrust
enforcement authorities or competition authorities of any other nation or other
jurisdiction or any other Person may assert under relevant antitrust or
competition laws

                                       33
<PAGE>

with respect to the transactions contemplated hereby, subject to Parent's right
to direct such actions and things to be done set forth in Section 5.8(b) below.

         (b) Without limiting the generality of the undertakings pursuant to
Section 5.8(a): (i) each of Parent and the Company shall provide promptly to the
Governmental Entities with regulatory jurisdiction over enforcement of any
applicable antitrust laws (each a, "Government Antitrust Entity") information
and documents requested by such Government Antitrust Entity or necessary, proper
or advisable to permit consummation of the transactions contemplated by this
Agreement; (ii) without in any way limiting the provisions of Section 5.8(a)(i)
above, each of Parent and the Company shall file any Notification and Report
Form and related material required under the HSR Act as soon as reasonably
practicable after the date of this Agreement, and thereafter use its
commercially reasonable efforts to certify as soon as reasonably practicable its
substantial compliance with any requests for additional information or
documentary material that may be made under the HSR Act, unless Parent in its
reasonable judgment determines that it is reasonable in the circumstances not to
comply substantially with any requests for additional information and
documentary material under the HSR Act; (iii) each of the Company and Parent
will keep the other informed of any material communication, and provide to the
other copies of all correspondence, between it (or its advisors) and any
Government Antitrust Entity relating to this Agreement or any of the matters
described in this Section 5.8(b); and (iv) each of the Company and Parent shall
permit the other to review any material communication to be given by it to, and
shall consult with each other in advance of any telephonic calls, meeting or
conference with, any Government Antitrust Entity and, to the extent permitted,
give the other party the opportunity to attend and participate in such
telephonic calls, meetings and conferences. Notwithstanding any of the
foregoing, no failure to obtain termination of the waiting period under the HSR
Act shall be deemed to be a breach hereunder by the Company or Parent. Subject
to the foregoing, Parent shall be principally responsible for and in control of
the process of dealing with any Government Antitrust Entity. Notwithstanding the
provisions of Section 5.8(a) and 5.8(b), in the event that either Parent or the
Company is requested, as a condition to obtaining the approval of any
Governmental Antitrust Entity to the transactions contemplated hereunder, to
take any action which if taken would have a Material Adverse Effect on the
combined consolidated businesses, assets, operations or prospects of Parent and
Company, then neither Parent nor the Company shall be required to take such
action and no failure by either Parent or the Company to take such action shall
be deemed a breach of this Section 5.8 or of any other provision of this
Agreement.

    Section 5.9 Further Assurances. In case at any time after the Effective Time
any further action is necessary or desirable to carry out the purposes of this
Agreement, the proper officers of the Company and Parent shall take all such
necessary action.

    Section 5.10 No Solicitation by the Company.

         (a) The Company agrees that it, prior to the Effective Time, shall not,
directly or indirectly, nor shall it permit any of its Subsidiaries to, nor
shall it authorize or permit any officer, director, employee or agent of, or any
investment banker, attorney, accountant or other advisor or representative of,
the Company or any of its Subsidiaries (collectively, the "Company
Representatives") to, directly or indirectly through another Person, solicit,
initiate, encourage,

                                       34
<PAGE>

induce or facilitate the making, submission or announcement of any Acquisition
Proposal, or participate in any discussions or negotiations regarding, or
furnish to any Person any information with respect to, or take any other action
to facilitate any inquiries or the making of any proposal that constitutes, or
would reasonably be expected to lead to, any Acquisition Proposal, or approve,
endorse or recommend any Acquisition Proposal, or enter into any letter of
intent, agreement in principle, acquisition agreement or other document or
contract contemplating or otherwise relating to an Acquisition Proposal,
provided, however, that, prior to the adoption and approval of this Agreement by
the requisite Company Stockholder Approval, the foregoing shall not prohibit the
Company from furnishing information to or entering into discussions or
negotiations with, any Person that makes an unsolicited bona fide proposal to
enter into a business combination with the Company pursuant to an Acquisition
Proposal which the Board of Directors of the Company (or any committee thereof
considering such proposal) in good faith determines is reasonably likely to be
more favorable to the Company's stockholders than the transactions contemplated
by this Agreement (a "Superior Proposal"), so long as:

              (i) prior to furnishing any information to, or entering into
discussions or negotiations with, such a Person the Company provides 48 hours'
advance written notice to Parent to the effect that it is furnishing information
to, or entering into substantive discussions or negotiations with, a Person from
whom the Company shall have received an executed confidentiality agreement in
form and substance similar to the Confidentiality Agreement prior to furnishing
such information;

              (ii) such notice shall include the terms and conditions of such
Acquisition Proposal or any agreement proposed by, or any information supplied
to, any such Person;

              (iii) prior to furnishing any nonpublic information to any such
Person, the Company furnishes such nonpublic information to Parent (to the
extent that such nonpublic information has not been previously furnished by the
Company to Parent);

              (iv) neither the Company nor any of its Subsidiaries nor any of
the Company Representatives shall have violated any of the restrictions set
forth in this Section 5.10;

              (v) such unsolicited bona fide proposal relating to a Superior
Proposal is made by a third party that the Board of Directors of the Company (or
any committee thereof considering such proposal) determines in good faith has
the good faith intent to proceed with negotiations to consider such Superior
Proposal;

              (vi) the Board of Directors of the Company (or any committee
thereof considering such proposal), after duly considering the written advice of
outside legal counsel to the Company, determines in good faith that such action
is required for the Board of Directors of the Company to comply with its
fiduciary duties to stockholders imposed by applicable law; and

              (vii) the Company uses all reasonable efforts to keep Parent
informed in all material respects of the status and terms of any such
negotiations or discussions (including without limitation the identity of the
Person with whom such negotiations or discussions are

                                       35
<PAGE>

being held) and provides Parent copies of such written proposals and any
amendments or revisions thereto or correspondence related thereto.

         (b) The Company shall notify Parent orally and in writing of the fact
that it has received inquiries, offers or proposals that it reasonably believes
to be bona fide with respect to an Acquisition Proposal within 24 hours after
the Company obtains Knowledge of the receipt thereof. The Company will
immediately cease and cause to be terminated any existing activities,
discussions or negotiations with any other Person that have been conducted
heretofore with respect to a potential Acquisition Proposal. The Company agrees
to inform the Company Representatives of the obligations undertaken in this
Section 5.10; provided, however, that nothing contained in this Agreement shall
prevent the Board of Directors of the Company from referring any third-party to
this Section 5.10.

         (c) The Company agrees not to release or permit the release of any
Person from, or to waive or permit the waiver of any provision of, any
confidentiality, "standstill" or similar agreement to which the Company or any
of its Subsidiaries is a party, and will use its best efforts to enforce or
cause to be enforced each such agreement at the request of Parent.

         (d) Except as expressly permitted by this Section 5.10, neither the
Board of Directors of the Company nor any committee thereof shall (i) withdraw,
modify or change, or propose publicly to withdraw, modify or change, in a manner
adverse to Parent, the approval or recommendation by such Board of Directors or
such committee of the Merger or this Agreement, (ii) approve or recommend, or
propose publicly to approve or recommend, any Superior Proposal or (iii) cause
the Company to enter into any letter of intent, agreement in principle,
acquisition agreement or other similar agreement (each, an "Acquisition
Agreement") related to any Acquisition Proposal. Notwithstanding the foregoing,
in the event that the Board of Directors of the Company (or any committee
thereof considering an Acquisition Proposal) determines in good faith, after
consultation with outside counsel, that in light of a Superior Proposal it is
necessary to do so in order to act in a manner consistent with its fiduciary
duties to the Company's stockholders under applicable law, the Board of
Directors of the Company may (subject to this and the following sentences)
withdraw, modify or change its recommendation of the Merger, but only after 48
hours following Parent's receipt of written notice advising Parent that the
Board of Directors of the Company is prepared to do so, and only if, during such
48- hour period, the Company and its advisors shall have negotiated in good
faith with Parent to make such adjustments in the terms and conditions of this
Agreement as would enable Parent to proceed with the transactions contemplated
herein on such adjusted terms.

         (e) Nothing contained in this Section 5.10 shall prohibit the Company
from taking and disclosing to its stockholders a position contemplated by Rules
14d-9 and/or 14e-2(a) promulgated under the Exchange Act or from making any
disclosure to the Company's stockholders if, in the good faith judgment of the
Board of Directors of the Company, after consultation with outside counsel,
failure so to disclose would be inconsistent with its obligations under
applicable law.

    Section 5.11 Director and Officer Liability.

                                       36
<PAGE>

         (a) Parent, Merger Sub and the Company agree that all rights to
indemnification and all limitations on liability existing in favor of any
Indemnitee (as defined below) as provided in the Company's Amended and Restated
Certificate of Incorporation, Company's By-laws, the charter or By-laws of any
Subsidiary of the Company or any Indemnity Agreement (as defined below) shall
survive the Merger and continue in full force and effect. To the extent
permitted by (i) the DGCL, (ii) the Company's Amended and Restated Certificate
of Incorporation, the Company's By-laws, the charter or By-laws of any
Subsidiary of the Company or (iii) any agreement providing for indemnification
by the Company or any Subsidiary of the Company of any Indemnitee in effect on
the date of this Agreement (including any indemnity provisions contained in any
agreement providing for the registration of securities) (each, an "Indemnity
Agreement"), advancement of Indemnitee Expenses (as defined below) pursuant to
this Section 5.11 shall be mandatory rather than permissive and the Parent shall
cause the Surviving Corporation to advance Costs (as defined below) in
connection with such indemnification. Parent shall cause the Surviving
Corporation to honor in accordance with their terms all Indemnity Agreements. In
the event that the Surviving Corporation fails to make any payments required or
permitted under any Indemnity Agreement, Parent agrees to make all such payments
within 15 days thereafter.

         (b) For a period of six (6) years after the Effective Time, Parent
shall, or shall cause the Surviving Corporation to, maintain officers' and
directors' liability insurance and fiduciary liability insurance covering the
Indemnitees who are currently covered by the Company's existing officers' and
directors' or fiduciary liability insurance policies on terms no less
advantageous to such indemnified parties than such existing insurance; provided,
however, that neither Parent nor the Surviving Corporation will be required in
order to maintain such policies to pay an annual premium in excess of 150% of
the greater of (i) the last annual premium paid by the Company prior to the date
of this Agreement and (ii) the annual premium for the year in which the Closing
occurs (the "Cap"); and provided, further, that, if equivalent coverage cannot
be obtained, or can be obtained only by paying an annual premium in excess of
the Cap, then Parent shall, or shall cause the Surviving Corporation to,
maintain policies that, in Parent's good faith judgment, provide the maximum
coverage available at an annual premium equal to the Cap.

         (c) In addition to the other rights provided for in this Section 5.11
and not in limitation thereof, for six (6) years from and after the Effective
Time, Parent shall cause the Surviving Corporation to, to the fullest extent
permitted by applicable law, (i) indemnify and hold harmless the individuals who
on or prior to the Effective Time were officers, directors or employees of the
Company or any of its Subsidiaries, and the heirs, executors, trustees,
fiduciaries and administrators of such officers, directors or employees and each
person who served at the request, or on behalf, of the Company or any of its
Subsidiaries as an officer, director or employee of another corporation,
partnership, trust, joint venture, pension or other employee benefit plan or
enterprise (collectively, the "Indemnitees") against all losses, Indemnitee
Expenses (as hereinafter defined), claims, damages, liabilities, judgments, or
amounts paid in settlement (collectively, "Costs") in respect to any threatened,
pending or completed claim, action, suit or proceeding, whether criminal, civil,
administrative or investigative based on, or arising out of or relating to the
fact that such person is or was a director, officer or employee of the Company
or any of its Subsidiaries or served at the request,

                                       37
<PAGE>

or on behalf, of the Company or any of its Subsidiaries and arising out of acts
or omissions occurring on or prior to the Effective Time (including, without
limitation, in respect of acts or omissions in connection with this Agreement
and the transactions contemplated hereby) (an "Indemnifiable Claim") and (ii)
advance to such Indemnitees all Indemnitee Expenses incurred in connection with
any Indemnifiable Claim promptly after receipt of reasonably detailed statements
therefor; provided that, except as otherwise provided pursuant to any Indemnity
Agreement, the person to whom Indemnitee Expenses are to be advanced provides an
undertaking to repay such advances if it is ultimately determined that such
person is not entitled to indemnification from Parent or the Surviving
Corporation. In the event that the Surviving Corporation fails to make any
payments required or permitted under this Section 5.11(c), Parent agrees to make
all such payments within 15 days thereafter. In the event any Indemnifiable
Claim is asserted or made within such six year period, all rights to
indemnification and advancement of Indemnitee Expenses in respect of any such
Indemnifiable Claim shall continue until such Indemnifiable Claim is disposed of
or all judgments, orders, decrees or other rulings in connection with such
Indemnifiable Claim are fully satisfied; provided, however, that Parent shall
not be liable for any settlement effected without its written consent (which
consent shall not be unreasonably withheld or delayed). Except as otherwise may
be provided pursuant to any Indemnity Agreement, the Indemnitees as a group may
retain only one law firm with respect to each related matter except to the
extent there is, in the opinion of counsel to an Indemnitee, under applicable
standards of professional conduct, a conflict on any significant issue between
positions of any two or more Indemnitees. For the purposes of this Section 5.11,
"Indemnitee Expenses" shall include reasonable attorneys' fees and all other
costs, charges and expenses paid or incurred in connection with investigating,
defending, being a witness in or participating in (including on appeal), or
preparing to defend, be a witness in or participate in any Indemnifiable Claim.

         (d) Notwithstanding any other provisions hereof, the obligations of the
Company, the Surviving Corporation and Parent contained in this Section 5.11

Corporation. In the event Parent or the Surviving Corporation or any of their
respective successors or assigns (i) consolidates with or merges into any other
Person or (ii) transfers all or substantially all of its properties or assets to
any Person, then, and in each case, proper provision shall be made so that

         (e) The obligations of the Company, the Surviving Corporation, and
Parent under this Section 5.11 shall survive the consummation of the Merger and
shall not be terminated or modified in such a manner as to adversely affect any
Indemnitee to whom this Section 5.11 applies without the consent of such
affected Indemnitee (it being expressly agreed that the Indemnitees to whom this
Section 5.11 applies shall be third party beneficiaries of this Section 5.11,
each of whom may enforce the provisions of this Section 5.11).

         (f) Parent shall cause the Surviving Corporation to advance all
Indemnitee Expenses to any Indemnitee incurred enforcing the indemnity or other
obligations provided for in this Section 5.11.

each use reasonable efforts to cause to be delivered to each other letters from
their respective independent accountants, dated a date within two business days
before the effective date of the Registration Statement, in form reasonably
satisfactory to the recipient and customary in scope for comfort letters

material respects, the financial position of the Company and its consolidated
Subsidiaries or Parent and its consolidated Subsidiaries, as the case may be, as
of the dates thereof and their results of operations and changes in financial
position or other information included therein for the periods or as of the

its reasonable efforts to cause the Merger to qualify, and will not knowingly
take any actions or cause any actions to be taken which could prevent the Merger
from qualifying, as a reorganization under the provisions of Section 368(a) of
the Code. Following the Effective Time, neither the Surviving Corporation,
Parent nor any of their affiliates shall knowingly take any action or knowingly
cause any action to be taken which would cause the Merger to fail to qualify as

shall timely pay any stock transfer and stamp taxes, any transfer, recording,
registration and other fees, and any similar taxes or fees not including any

questionnaires, applications, or other documents regarding any such Conveyance
Taxes.

consultants, but excluding the fees and expenses of legal counsel and investment
bankers) related to preparing, printing, filing and mailing the Registration
Statement, the Proxy Statement and all SEC and other regulatory filing fees
incurred in connection with the Registration Statement, Proxy Statement and HSR

              (i) Parent terminates this Agreement pursuant to Section 7.1(g);

              (ii) Parent terminates this Agreement pursuant to Section 7.1(d)
as a direct result of a material breach by the Company of a representation,
warranty or covenant under this Agreement that is within the control of the
Company or Parent terminates this Agreement pursuant to Section 7.1(b) at a time
that a Company Breach (as defined in Section 7.1(d)) within the control of the
Company exists; or

              (iii) the Company or Parent terminates this Agreement pursuant to
Section 7.1(f) due to the failure to receive Company Stockholder Approval;

(A) a transaction is consummated, which transaction, if offered or proposed,
    would constitute an Acquisition Proposal;

(B) a definitive agreement (the execution and delivery of which has been
    authorized by the boards of directors, or comparable bodies, that would if
    consummated constitute an Acquisition Proposal) for such a transaction is
    entered into and such transaction is

                                       40
<PAGE>

    consummated whether or not within such ten-month period; or

(C) any Person shall have acquired beneficial ownership or the right to acquire
    beneficial ownership of, or any "group" (as such term is defined under
    Section 13(d) of the Exchange Act and the rules and regulations promulgated
    hereunder), shall have been formed that beneficially owns, or has the right
    to acquire beneficial ownership of, outstanding shares of capital stock of
    the Company then representing 50% or more of any class of the Company Common

    Sillerman and his Affiliates with respect to the shares of Company Common
    Stock beneficially owned by Mr. Sillerman or his Affiliates as of the date

(B) or (C), the Company shall pay to Parent a termination fee of $100 million,
plus the reasonably documented Expenses of Parent up to $20 million (in each
case, less any amounts paid by the Company to Parent pursuant to the following
paragraph). Parent may assert its right to the termination fee and Expenses
under one or more cases set forth under this Section 5.17(c), but in no event
shall Parent receive a termination fee or fees of more than $100 million or
reimbursement of Expenses in an amount of more than $20 million under this
Section 5.17.

         Without limiting the foregoing, if Parent terminates this Agreement

Company shall pay to Parent a termination fee of $50 million, plus the
reasonably documented Expenses of Parent of up to $20 million.

         (d) Notwithstanding the provisions of Section 5.17(c), if the Company

failure to receive Company Stockholder Approval and (x) at the time of such
termination, Parent shall not have a right to terminate this Agreement pursuant
to Section 7.1(g), (y) the Company does not enter into an Acquisition Agreement
within seventy-five (75) days after the date of such termination and (z) the

million) pursuant to Section 5.17(c).

Clear Channel Communications, Inc.
200 Concord Plaza, Suite 600
San Antonio, TX  78216

Ladies and Gentlemen:

     Reference is made to the Agreement and Plan of Merger (the "MERGER
AGREEMENT") dated as of February 28, 2000, among Clear Channel Communications,
Inc., a Texas corporation ("PARENT"), CCU II Merger Sub, Inc., a Delaware
corporation and a wholly owned subsidiary of Parent ("MERGER SUB"), and SFX
Entertainment, Inc., a Delaware corporation (the "COMPANY"), pursuant to which
Merger Sub will be merged with and into the Company.

     The undersigned understands that it may be deemed to be an "AFFILIATE" of
the Company for purposes of Rule 145 promulgated under the Securities Act of
1933, as amended (the "ACT"). The undersigned is delivering this letter of
undertaking and commitment pursuant to Section 5.6 of the Merger Agreement.

     With respect to such securities of Parent as may be received by the
undersigned pursuant to the Merger Agreement (the "SHARES"), the undersigned
represents to and agrees with Parent that:

          A. The undersigned will not make any offer to sell or any sale or
     other disposition of all or any part of the Shares in violation of the Act
     or the rules and regulations thereunder, including Rule 145, and will hold
     all the Shares subject to all applicable provisions of the Act and the
     rules and regulations thereunder.

          B. The undersigned has been advised that the offering, sale and
     delivery of the Shares to the undersigned pursuant to the Merger Agreement
     will be registered under the Act on a Registration Statement on Form S-4.
     The undersigned has also been advised, however, that, since the undersigned
     may be deemed an "AFFILIATE" of the Company, any public reoffering or
     resale by the undersigned of any of the Shares will, under current law,
     require either (i) the further registration under the Act of the Shares to
     be sold, (ii) compliance with Rule 145 promulgated under the Act
     (permitting limited sales under certain circumstances) or (iii) the
     availability of another exemption from registration under the Act.

          C. The undersigned also understands that, if Parent should deem it
     necessary to comply with the requirements of the Act, stop transfer
     instructions will be given to its transfer agents with respect to the
     Shares and that there will be placed on the certificates for the Shares, or
     any substitutions therefor, a legend stating in substance:

     "The securities represented by this certificate were issued in a
     transaction under Rule 145 promulgated under the Securities Act of 1933, as
     amended (the "ACT"), and may be sold, transferred or otherwise disposed of
     only upon receipt by the Corporation of an opinion of counsel acceptable to
     it that the securities are being sold in compliance with the limitations of
     Rule 145 or that some other exemption from registration under the Act is
     available, or pursuant to a registration statement under the Act."

     Execution of this letter shall not be considered an admission on the part
     of the undersigned that the undersigned is an "AFFILIATE" of the Company
     for purposes of Rule 145 under the Act or as waiver of any rights the
     undersigned may have to any claim that the undersigned is not such an
     affiliate on or after the date of this letter.

                                       Very truly yours,

                                EXHIBIT 6.1(a)-1

                 CLEAR CHANNEL COMMUNICATIONS, INC. CERTIFICATE

    In connection with the merger (the "Merger") of __________ Merger Sub, Inc.
("Merger Sub"), a direct wholly-owned subsidiary of Clear Channel
Communications, Inc. ("Parent") with and into SFX Entertainment, Inc.
("Company") pursuant to the Agreement and Plan of Merger dated as of
_________________________, 2000 by and among Parent, Merger Sub and Company (the
"Merger Agreement"), Parent hereby certifies, on behalf of Parent and Merger
Sub, the following:

1.  The aggregate fair market value of the common stock of Parent ("Parent
    Common Stock") and cash in lieu of fractional shares of Parent Common Stock,
    if any, received by the stockholders of Company in the Merger will be
    approximately equal to the aggregate fair market value of the common stock
    of Company ("Company Common Stock") surrendered in the exchange.

2.  The payment of cash in lieu of fractional shares of Parent Common Stock in
    the Merger is solely for the purpose of avoiding the expense and
    inconvenience to Parent of issuing fractional shares of Parent Common Stock
    and does not represent separately bargained for consideration.

3.  In connection with the Merger, less than 5% of the Company Common Stock will
    be acquired for consideration other than Parent Common Stock, except for
    cash received in lieu of fractional shares of Parent Common Stock, by (i)
    Parent, (ii) a member of an Affiliated Group (as defined below) in which
    Parent is a member, or (iii) a corporation in which Parent (or any
    predecessor or successor corporation) owns, or which owns with respect to
    Parent (or any predecessor or successor corporation), directly or
    indirectly, immediately before or immediately after such acquisition, at
    least 50% of the total combined voting power of all classes of stock
    entitled to vote or at least 50% of the total value of shares of all classes
    of stock, taking into account for purposes of this clause (iii), any stock
    owned directly or indirectly by 5% or greater stockholders of Parent (or any
    predecessor or successor corporation) or such corporation, stock owned
    directly or indirectly by entities in which Parent (or any predecessor or
    successor corporation) or such corporation owns a 5% or greater interest,
    and any stock which may be acquired pursuant to exercise of options (a "50%
    Subsidiary"). For purposes of this certificate, "Affiliated Group" shall
    mean one or more chains of corporations connected through stock ownership
    with a common parent corporation, but only if the common parent owns
    directly at least 80% of the total voting power of the stock and at least
    80% of the total value of the stock in at least one of the other
    corporations and at least 80% of the total voting power of the stock and at
    least 80% of the total value of the stock in each corporation (except the
    common parent) is owned directly by one or more of the other corporations.
    For purposes of the preceding sentence, "stock" does not include any stock
    which (a) is not entitled to vote, (b) is limited and preferred as to
    dividends and does not participate in corporate growth to any significant
    extent, (c) has redemption and liquidation rights which do not exceed the
    issue price of such stock (except for a

<PAGE>

    reasonable redemption or liquidation premium), and (d) is not convertible
    into another class of stock.

4.  In the Merger, shares of Company Common Stock representing Control (as
    defined below) of Company will be exchanged solely for voting Parent Common
    Stock. For purposes of this representation, any shares of Company Common
    Stock exchanged for cash or other property originating with Parent, or any
    person related to Parent (as described in clauses (ii) and (iii) of
    paragraph 3 of this certificate), will be treated as outstanding Company
    Common Stock on the date of the Merger. For purposes of this certificate,
    "Control" shall mean ownership of at least 80% of the total combined voting
    power of all classes of stock entitled to vote and at least 80% of the total
    number of shares of each other class of stock of the controlled corporation.

5.  Following the Merger, Parent will cause Company to hold at least 90% of the
    fair market value of its net assets and at least 70% of the fair market
    value of its gross assets held immediately prior to the Merger and at least
    90% of the fair market value of the net assets and at least 70% of the fair
    market value of the gross assets of Merger Sub held immediately before the
    Merger. For purposes of this representation, assets transferred from Parent
    to Merger Sub are not included as assets of Merger Sub immediately before
    the Merger where such assets are used to pay dissenters, to pay
    reorganization expenses, to pay creditors of Company or to enable Merger Sub
    to satisfy state minimum capitalization requirements (where the money is
    returned to Parent as part of the transaction).

6.  Following the Merger, the historic business of Company will be continued by,
    or a significant portion of Company's historic business assets will be used
    in a business of Parent or a corporation within Parent's Qualified Group (as
    defined below). Parent has no plan or intention to (a) liquidate Company;
    (b) merge Company with or into another corporation; (c) sell, distribute or
    otherwise dispose of the Company Common Stock acquired in the Merger or (d)
    cause or permit Company to sell or otherwise dispose of any of its assets or
    any of the assets acquired from Merger Sub, except, in the case of (d), for
    dispositions of assets made in the ordinary course of business or, in the
    case of (c) and (d), transfers or successive transfers to one or more
    corporations of which the transferor owns at least 80% of the total combined
    voting power of all classes of stock entitled to vote and at least 80% of
    the total number of shares of each other class of stock of such corporation
    or sales, transfers or other dispositions of assets that, in the aggregate,
    would not result in Parent or members of its Qualified Group (as defined
    below) failing to continue the historic business of Company or to use a
    significant portion of Company's historic business assets in a business. For
    purposes of this certificate, "Qualified Group" means one or more chains of
    corporations connected to Parent through stock ownership, but only if (i)
    Parent owns directly stock possessing at least 80% of the total combined
    voting power of all classes of stock entitled to vote and at least 80% of
    the total number of shares of each other class of stock in at least one
    other corporation in such chain, and (ii) one of the other corporations owns
    directly stock possessing at least 80% of the total combined voting power of
    all classes of stock entitled

<PAGE>

    to vote and at least 80% of the total number of shares of each other class
    of stock in each of the corporations, other than Parent, in the chain.

7.  Parent has no plan or intention to cause Company to issue additional shares
    of Company Common Stock that would result in Parent losing Control of
    Company.

8.  Parent has no plan or intention to reacquire, or cause (i) a member of its
    Affiliated Group or (ii) a 50% Subsidiary to acquire, any of the Parent
    Common Stock issued to the holders of Company Common Stock pursuant to the
    Merger.

9.  Parent, Company and the stockholders of Company will pay their respective
    expenses, if any, incurred in connection with the Merger except as otherwise
    provided in Section 5.17 of the Merger Agreement.

10. Neither Parent nor Merger Sub is a regulated investment company, a real
    estate investment trust, or a corporation 50% or more of the value of whose
    assets are stock and securities and 80% or more of the value of whose total
    assets are assets held for investment (each, an "Investment Company"). For
    purposes of this representation, in making the 50% and 80% determinations
    under the preceding sentence, stock and securities in any subsidiary
    corporation shall be disregarded and a parent shall be deemed to own its
    ratable share of the subsidiary's assets, and a corporation shall be
    considered a subsidiary if the parent owns 50% or more of the combined
    voting power of all classes of stock entitled to vote, or 50% or more of the
    total value of shares of all classes of stock outstanding. In determining
    total assets there shall be excluded cash and cash items (including
    receivables), government securities, and assets acquired (through incurring
    indebtedness or otherwise) for purposes of ceasing to be an Investment
    Company.

11. Prior to the Merger, Parent will be in Control of Merger Sub.

12. None of the Parent Common Stock to be received in the Merger by any
    stockholder of Company which is (or was) a service provider to Company will
    be separate consideration for, or allocable to, past or future services.
    None of the compensation to be received by any stockholder of Company who is
    (or was) a service provider to Company is separate consideration for, or
    allocable to, such stockholder's shares of Company Common Stock to be
    surrendered in the Merger, and the compensation to be paid to any such
    person will be for services actually rendered and will be commensurate with
    amounts paid to third parties bargaining at arm's length for similar
    services.

13. Merger Sub will have no liabilities assumed by Company and will not transfer
    to Company any assets subject to liabilities in the Merger. Merger Sub is a
    corporation newly formed for the purpose of participating in the Merger and
    at no time prior to the Merger has had assets (other than nominal assets
    contributed upon the formation of Merger Sub, which assets will be held by
    the Company following the Merger) or business operations.

<PAGE>

14. There is no intercorporate indebtedness existing between Parent and Company
    or between Merger Sub and Company that was issued, acquired or will be
    settled at a discount.

15. Neither Parent nor Merger Sub (nor any other subsidiary of Parent) has been
    a party to a distribution of stock qualifying for tax-free treatment (i) in
    the two years prior to the date of the Merger or (ii) in a distribution
    which is part of a plan (or series of related transactions) in conjunction
    with the Merger.

16. Except for a recent purchase of less than 5% of the Company Common Stock by
    Parent, neither Parent, a member of its Affiliated Group nor a 50%
    Subsidiary has owned during the past five years any shares of stock of
    Company.

17. The Merger Agreement represents the full and complete agreement between
    Parent, Merger Sub and Company regarding the Merger, and there are no other
    written or oral agreements regarding the Merger other than those expressly
    referred to in the Merger Agreement.

18. No stock of Merger Sub will be issued in the Merger.

19. There will be no dissenters to the Merger.

    Parent understands that Paul, Hastings, Janofsky & Walker LLP, as tax
counsel for Company, and Akin, Gump, Strauss, Hauer & Feld, L.L.P., as counsel
for Parent, will rely on this certificate in rendering their opinion concerning
certain of the federal income tax consequences of the Merger and hereby commit
to inform them if, for any reason, any of the foregoing representations ceases
to be true prior to the date of the Merger.

                       SFX ENTERTAINMENT, INC. CERTIFICATE

    In connection with the merger (the "Merger") of CCU II Merger Sub, Inc.
("Merger Sub"), a direct wholly-owned subsidiary of Clear Channel
Communications, Inc. ("Parent") with and into SFX Entertainment, Inc.
("Company") pursuant to the Agreement and Plan of Merger dated as of February
___, 2000 by and among Parent, Merger Sub and Company (the "Merger Agreement"),
Company hereby certifies the following:

1. The aggregate fair market value of the common stock of Parent ("Parent Common
Stock") and cash in lieu of fractional shares of Parent Common Stock, if any,
received by the stockholders of Company in the Merger will be approximately
equal to the aggregate fair market value of the common stock of Company
("Company Common Stock") surrendered in the exchange.

2. The payment of cash in lieu of fractional shares of Parent Common Stock in
the Merger is solely for the purpose of avoiding the expense and inconvenience
to Parent of issuing fractional shares of Parent Common Stock and does not
represent separately bargained for consideration.

3. Prior to and in connection with the Merger, no outstanding stock of Company
has been (i) redeemed by Company, (ii) acquired by a corporation (including by
reason of an acquisition by a partnership in which the corporation is a partner)
in which Company (or any predecessor or successor corporation) owns, or which
owns with respect to Company (or any predecessor or successor corporation),
directly or indirectly, immediately before or immediately after such
acquisition, at least 50% of the total combined voting power of all classes of
stock entitled to vote or at least 50% of the total value of shares of stock,
taking into account for purposes of this clause (ii), any stock owned directly
or indirectly by 5% or greater stockholders of Company (or any predecessor or
successor corporation) or such corporation, stock owned directly or indirectly
by entities in which Company (or any predecessor or successor corporation) or
such corporation owns a 5% or greater interest, and any stock which may be
acquired pursuant to the exercise of options (a "50% Subsidiary"), for
consideration other than Company Common Stock or (iii) the subject of any
extraordinary distribution by Company.

4. To the best knowledge of Company, there is no plan or intention on the part
of any particular stockholder of Company to sell, exchange or otherwise dispose
of Parent Common Stock to be received in the Merger directly or indirectly, to
any of (i) Parent (or any predecessor or successor corporation), (ii) a
corporation that, immediately before or immediately after such sale, exchange,
or other disposition, is a member of an Affiliated Group (as defined below) of
which Parent (or any predecessor or successor corporation) is a member, or (iii)
a 50% Subsidiary of Parent. For purposes of this certificate, "Affiliated Group"
shall mean one or more chains of corporations connected through stock ownership
with a common parent corporation, but only if the common parent owns directly at
least 80% of the total voting power of the stock and at least 80% of the total
value of the stock in at least one of the other corporations and at least 80% of
the total voting power of the stock and at least 80% of the total value of the
stock in

<PAGE>

each corporation (except the common parent) is owned directly by one or more of
the other corporations. For purposes of the preceding sentence, "stock" does not
include any stock which (a) is not entitled to vote, (b) is limited and
preferred as to dividends and does not participate in corporate growth to any
significant extent, (c) has redemption and liquidation rights which do not
exceed the issue price of such stock (except for a reasonable redemption or
liquidation premium), and (d) is not convertible into another class of stock.

5. On the date of the Merger, Company will not have outstanding any warrants,
options, convertible securities, or any other type of right pursuant to which
any person could acquire stock in Company except as provided in the Merger
Agreement.

6. Company has no plan or intention, prior to the date of the Merger, to issue
additional shares of its stock that would result in Parent failing to gain
Control of Company pursuant to the Merger Agreement.

7. Parent, Company and the stockholders of Company will pay their respective
expenses, if any, incurred in connection with the Merger except as otherwise
provided in Section 5.17 of the Merger Agreement.

8. Company is not a regulated investment company, a real estate investment
trust, or a corporation 50% or more of the value of whose assets are stock and
securities and 80% or more of the value of whose total assets are assets held
for investment (each, an "Investment Company"). For purposes of this
representation, in making the 50% and 80% determinations under the preceding
sentence, (i) stock and securities in any subsidiary corporation shall be
disregarded and the parent corporation shall be deemed to own its ratable share
of the subsidiary's assets, and (ii) a corporation shall be considered a
subsidiary if the parent owns 50% or more of the combined voting power of all
classes of stock entitled to vote or 50% or more of the total value of shares of
all classes of stock outstanding. In determining total assets there shall be
excluded cash and cash items (including receivables), government securities, and
assets acquired (through incurring indebtedness or otherwise) for purposes of
ceasing to be an Investment Company.

the United States Code, or a receivership, foreclosure, or similar proceeding in
a federal or state court.

10. There is no intercorporate indebtedness existing between Parent and Company
or between Merger Sub and Company that was issued, acquired or will be settled
at a discount.

11. In the Merger, shares of Company Common Stock representing Control of
Company will be exchanged solely for voting Parent Common Stock. For purposes of
this representation, any shares of Company Common Stock exchanged for cash or
other property originating with Parent or a direct or indirect subsidiary of
Parent will be treated as outstanding Company Common Stock on the date of the
Merger.

12. In contemplation of or as part of the Merger, Company has not sold,
transferred or otherwise disposed of any of its assets to the extent that would
prevent Parent or members of its

<PAGE>

Qualified Group (as defined below) from causing Company after the Merger to
continue the historic business of Company or to use a significant portion of
Company's historic business assets in a business. For purposes of this
certificate, "Qualified Group" means one or more chains of corporations
connected with Parent through stock ownership, but only if (i) Parent owns
directly stock possessing at least 80% of the total combined voting power of all
classes of stock entitled to vote and at least 80% of the total number of shares
of each other class of stock in at least one other corporation in such chain,
and (ii) one of the other corporations owns directly stock possessing at least
80% of the total combined voting power of all classes of stock entitled to vote
and at least 80% of the total number of shares of each other class of stock in
each of the corporations, other than Parent, in the chain.

13. Following the Merger, Company will hold at least 90% of the fair market
value of its net assets and at least 70% of the fair market value of its gross
assets held immediately prior to the Merger and at least 90% of the fair market
value of the net assets and at least 70% of the fair market value of the gross
assets of Merger Sub held immediately before the Merger. For purposes of this

assets of Merger Sub immediately before the Merger where such assets are used to
pay dissenters, to pay reorganization expenses, to pay creditors of Company or
to enable Merger Sub to satisfy state minimum capitalization requirements (where
the money is returned to Parent as part of the transaction).

14. None of the Parent Common Stock to be received in the Merger by any
stockholder of Company which is (or was) a service provider to Company will be
separate consideration for, or allocable to, past or future services. None of
the compensation to be received by any stockholder of Company who is (or was) a
service provider to Company is separate consideration for, or allocable to, such
stockholder's shares of Company Common Stock to be surrendered in the Merger,
and the compensation to be paid to any such person will be for services actually
rendered and will be commensurate with amounts paid to third parties bargaining
at arm's length for similar services.

15. On the date of the Merger, the fair market value of the assets of Company
will exceed the sum of its liabilities, plus the amount of liabilities, if any,
to which the assets are subject.

16. Neither Company nor any of its subsidiaries has been a party to a
distribution of stock qualifying for tax-free treatment (i) in the two years
prior to the date of the Merger or (ii) in a distribution which is part of a
plan (or series of related transactions) in conjunction with the Merger.

17. The Merger Agreement represents the full and complete agreement between
Parent, Merger Sub and Company regarding the Merger, and there are no other
written or oral agreements regarding the Merger other than those expressly
referred to in the Merger Agreement.

Company understands that Akin, Gump, Strauss, Hauer & Feld, L.L.P., as counsel
for Parent, and Paul, Hastings, Janofsky & Walker LLP, as tax counsel for
Company, will rely on this certificate in rendering their opinion concerning
certain of the federal income tax consequences of the Merger and hereby commit
to inform them if, for any reason, any of the foregoing representations ceases
to be true prior to the date of the Merger.
