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

       The Company shall use its best efforts to keep any Shelf Registration

and amended as required by and subject to the provisions of Section 5(a) hereof
to the extent necessary to ensure that it is available for sales of Transfer

include any of its Transfer Restricted Securities in any Shelf Registration

the Company in writing, within 20 days after receipt of a request therefor, the
information specified in Item 507 or 508 of Regulation S-K, as applicable, of
the Act for use in connection with any Shelf Registration Statement or
Prospectus or preliminary Prospectus included therein.  No Holder of Transfer
Restricted Securities shall be entitled to liquidated damages pursuant to
Section 4 hereof unless and until such Holder shall have provided all such
information.  Each selling Holder agrees to promptly furnish additional
information required to be disclosed in order to make the information previously
furnished to the Company by such Holder not materially misleading.

     SECTION 4.    LIQUIDATED DAMAGES

     If (i) the Shelf Registration Statement is not filed with the Commission on
or prior to the Filing Deadline, (ii) such Shelf Registration Statement has not
been declared effective by the Commission on or prior to the Effectiveness
Deadline, or (iii) such Shelf Registration Statement required by this Agreement

(without being succeeded immediately by a post-effective amendment to such Shelf
Registration Statement that cures such failure and that is itself declared
effective) for a period of time which shall exceed 45 days in any 12 month
period  (each such event referred to in clauses (i) through (iii), a
"REGISTRATION DEFAULT"), then the Company hereby agrees to pay to each Holder of
---------------------                                                           
Transfer Restricted Securities affected thereby liquidated damages in an amount
equal to $2.50 per year per share of Preferred Stock (equivalent to $0.125 per
Depositary Share) or, if applicable, in an amount equal to $2.50 per year
(equivalent to $0.125 per Depositary Share) per the number of shares of Common
Stock constituting Transfer Restricted Securities held by such holder into which
each share of Preferred Stock or Depositary Share, respectively,  was converted
(subject to adjustment in the event of stock splits, stock recombinations, stock
dividends and the like, as provided for in the certificate of designation for
the Preferred Stock) for the first 45-day period immediately following the
occurrence of such Registration Default.  The amount of the liquidated damages
shall increase by an additional $2.50 per year per share of Preferred Stock
(equivalent to $0.125 per Depositary Share) or $2.50 per year (equivalent to
$0.125 per Depositary Share) per the number of shares of Common Stock

Defaults have been cured, up to a maximum amount of liquidated damages of $25.00
per year per share of Preferred Stock (equivalent to $1.25 per Depositary Share)
or $25.00 per year (equivalent to $1.25 per Depositary Share) per the number of
shares of Common Stock constituting Transfer Restricted Securities held by such
holder into which each share of Preferred Stock or Depositary Share,
respectively, was converted; provided that the Company shall in no event be
required to pay liquidated damages for more than one Registration Default at any
given time. Notwithstanding anything to the contrary set forth herein, (1) upon
filing of the Shelf Registration Statement, in the case of (i) above, (2) upon
the effectiveness of this Shelf Registration Statement, in the case of (ii)
above, or (3) upon the filing of a post-effective amendment to the Shelf
Registration Statement that causes the Shelf Registration Statement to again be
declared effective or made usable, in the case of (iii) above, the liquidated
damages payable with respect to the Transfer Restricted Securities as a result
of such clause (i), (ii), or (iii), as applicable, shall cease.

     All accrued liquidated damages shall be paid to the Holders entitled
thereto, in the manner provided for the payment of dividends on the Preferred
Stock on each quarterly payment date.

     SECTION 5.    SHELF REGISTRATION PROCEDURES

       (a) Procedures.  In connection with the Shelf Registration Statement, the
           ----------                                                           
Company shall:

              (i) use its best efforts to effect such registration to permit the
     sale of the Transfer Restricted Securities being sold in accordance with
     the intended method or methods of distribution thereof (as indicated in the
     information furnished to the Company pursuant to Section 3(b) hereof), and
     pursuant thereto the Company will prepare and file with the Commission a
     Shelf Registration Statement relating to the registration on any
     appropriate form under the Act, which form shall be available for the sale
     of the Transfer Restricted Securities in accordance with the intended
     method or methods of distribution thereof (including, without limitation,
     one or more underwritten offerings) within the time periods and otherwise
     in accordance with the provisions hereof.

              (ii) use its best efforts to obtain consent from those parties
     named in Schedule E attached to the Purchase Agreement not to exercise
     their right to require the Company to include their securities in the Shelf
     Registration Statement.
 
              (iii)  use its best efforts to contact all Holders of Transfer
     Restricted Securities and notify each Holder of its right to 

                                       6
<PAGE>
 
     include its Transfer Restricted Securities in such Shelf Registration
     Statement.

              (iv) use its best efforts to keep such Shelf Registration
     Statement continuously effective and provide all requisite financial
     statements for the period specified in Section 3 of this Agreement.  Upon
     the occurrence of any event that would cause any such Shelf Registration
     Statement or the Prospectus contained therein (A) to contain an untrue
     statement of a material fact or omit to state any material fact necessary
     to make the statements therein not misleading or (B) not to be effective
     and usable for resale of Transfer Restricted Securities during the period
     required by this Agreement, the Company shall file promptly an appropriate
     amendment to such Shelf Registration Statement curing such defect, and, if
     Commission review is required, use its best efforts to cause such amendment
     to be declared effective as soon as practicable.

              (v) prepare and file with the Commission such amendments and post-
     effective amendments to the Shelf Registration Statement as may be
     necessary to keep such Shelf Registration Statement effective for the
     applicable period set forth in Section 3 hereof, cause the Prospectus to be
     supplemented by any required Prospectus supplement, and as so supplemented
     to be filed pursuant to Rule 424 under the Act, and to comply fully with
     Rules 424, 430A and 462, as applicable, under the Act in a timely manner;
     and comply with the provisions of the Act with respect to the disposition
     of all Transfer Restricted Securities covered by such Shelf Registration
     Statement during the applicable period in accordance with the intended
     method or methods of distribution by the sellers thereof set forth in such
     Shelf Registration Statement or supplement to the Prospectus;

              (vi) advise the Holders and underwriters, if any, promptly and, if
     requested by such persons, confirm such advice in writing, (A) when the
     Prospectus or any Prospectus supplement or post-effective amendment has
     been filed, and, with respect to any Shelf Registration Statement or any
     post-effective amendment thereto, when the same has become effective, (B)
     of any request by the Commission for amendments to the Shelf Registration
     Statement or amendments or supplements to the Prospectus or for additional
     information relating thereto, (C) of the issuance by the Commission of any
     stop order suspending the effectiveness of the Shelf Registration Statement
     under the Act or of the suspension by any state securities commission of
     the qualification of the Transfer Restricted Securities for offering or
     sale in any jurisdiction, or the initiation of any proceeding for any of
     the preceding purposes, and (D) of the existence of any 

                                       7
<PAGE>
 
     fact or the happening of any event that makes any statement of a material
     fact made in the Shelf Registration Statement, the Prospectus, any
     amendment or supplement thereto or any document incorporated by reference
     therein untrue, or that requires the making of any additions to or changes
     in the Shelf Registration Statement in order to make the statements therein
     not misleading, or that requires the making of any additions to or changes
     in the Prospectus in order to make the statements therein, in the light of
     the circumstances under which they were made, not misleading. If at any
     time the Commission shall issue any stop order suspending the effectiveness
     of the Shelf Registration Statement, or any state securities commission or
     other regulatory authority shall issue an order suspending the
     qualification or exemption from qualification of the Transfer Restricted
     Securities under state securities or Blue Sky laws, the Company shall use
     its best efforts to obtain the withdrawal or lifting of such order at the
     earliest possible time;

              (vii)  subject to Section 5(a)(iii), if any fact or event
     contemplated by Section 5(v)(D) above shall exist or have occurred, prepare
     a supplement or post-effective amendment to the Shelf Registration
     Statement or related Prospectus or any document incorporated therein by
     reference or file any other required document so that, as thereafter
     delivered to the purchasers of Transfer Restricted Securities, the
     Prospectus will not contain an untrue statement of a material fact or omit
     to state any material fact necessary to make the statements therein, in the
     light of the circumstances under which they were made, not misleading;

              (viii)  furnish to each Holder named in any Shelf Registration
     Statement or Prospectus and underwriter, if any, in connection with such
     sale before filing with the Commission, copies of any Shelf Registration
     Statement or any Prospectus included therein or any amendments or
     supplements to any such Shelf Registration Statement or Prospectus
     (including all documents incorporated by reference after the initial filing
     of such Shelf Registration Statement), which documents will be subject to
     the review and comment of such persons in connection with such sale, if
     any, for a period of at least three Business Days, and the Company will not
     file any such Shelf Registration Statement or Prospectus or any amendment
     or supplement to any such Shelf Registration Statement or Prospectus
     (including all such documents incorporated by reference) to which such
     persons shall reasonably object within five Business Days after the receipt
     thereof. Any such person shall be deemed to have reasonably objected to
     such filing if such Registration Statement, amendment, Prospectus or
     supplement, as applicable, as proposed to be 

                                       8
<PAGE>
 
     filed, contains an untrue statement of a material fact or omits to state
     any material fact necessary to make the statements therein not misleading

              (ix) make available at reasonable times for inspection by the

     other customary due diligence matters;

              (x) make available at reasonable times for inspection by the
     Holders and underwriters, if any, and any attorney or accountant retained

     officers, directors and employees to supply all information reasonably

     effectiveness;

              (xi) if requested by any Holders or underwriters, if any,  in
     connection with such sale, promptly include in any Shelf Registration
     Statement or Prospectus, pursuant to a supplement or post-effective
     amendment if necessary, such information as such Holders or underwriters,
     if any, may reasonably request to have included therein, including, without
     limitation, information relating to the "Plan of Distribution" of the
     Transfer Restricted Securities; and make all required filings of such
     Prospectus supplement or post-effective amendment as soon as practicable
     after the Company is notified of the matters to be included in such
     Prospectus supplement or post-effective amendment;

              (xii)  furnish to each Holder and underwriter, if any, without
     charge, at least one copy of the Shelf Registration Statement, as first
     filed with the Commission, and of each amendment thereto, including all
     documents incorporated by reference therein and all exhibits (including

              (xiii)  deliver to each Holder and underwriter, if any, without
     charge, as many copies of the Prospectus (including each preliminary
     prospectus) and any amendment or supplement thereto as such persons
     reasonably may request; the Company hereby consents to the use (in
     accordance with law) of the Prospectus and any amendment or supplement
     thereto by each Holder and each underwriter, if 

                                       9
<PAGE>
 
     any, in connection with the offering and the sale of the Transfer
     Restricted Securities covered by the Prospectus or any amendment or
     supplement thereto;

              (xiv)  upon the request of any Holder or underwriter, if any,
     enter into such agreements (including underwriting agreements) and make
     such representations and warranties and take all such other actions in
     connection therewith in order to expedite or facilitate the disposition of
     the Transfer Restricted Securities pursuant to any Shelf Registration
     Statement contemplated by this Agreement as may be reasonably requested by
     such person in connection with any sale or resale pursuant to any
     applicable Shelf Registration Statement and in such connection, the Company
     shall:

                    (A) upon request of any Holder or underwriter, if any,
          furnish (or in the case of paragraphs (2) and (3) below, use its best
          efforts to cause to be furnished) to each Holder or underwriter, if
          any, upon the effectiveness of the Shelf Registration Statement:

               (1) a certificate, dated such date, signed on behalf of the
     Company by (x) the President or any Vice President and (y) a principal
     financial or accounting officer of the Company, confirming, as of the
     date thereof, the matters set forth in Sections 6(v), 9(a) and 9(b) of the
     Purchase Agreement and such other similar matters as the Holders may
     reasonably request;

               (2) an opinion, dated the date effectiveness of the Shelf
     Registration Statement, of counsel for the Company covering matters similar
     to those set forth in paragraph (e) of Section 9 of the Purchase Agreement
     and such other matter as the selling Holders may reasonably request, and in
     any event including a statement to the effect that such counsel has
     participated in conferences with officers and other representatives of the
     Company, representatives of the independent public accountants for the
     Company and have considered the matters required to be stated therein and
     the statements contained therein, although such counsel has not
     independently verified the accuracy, completeness or fairness of such
     statements; and that such counsel advises that, on the basis of the
     foregoing no facts came to such counsel's attention that caused such
     counsel to believe that the Shelf Registration Statement, at the time such
     Shelf Registration Statement or any post-effective amendment thereto
     became effective, contained an untrue statement of a material fact or
     omitted to state a material fact required to be stated therein or necessary

                                       10
<PAGE>
 
     to make the statements therein not misleading, or that the Prospectus
     contained in such Shelf Registration Statement as of its date, contained an
     untrue statement of a material fact or omitted to state a material fact
     necessary in order to make the statements therein, in the light of the
     circumstances under which they were made, not misleading. Without limiting
     the foregoing, such counsel may state further that such counsel assumes no
     responsibility for, and has not independently verified, the accuracy,
     completeness or fairness of the financial statements, notes and schedules
     and other financial data included in any Registration Statement
     contemplated by this Agreement or the related Prospectus; and

               (3) a customary comfort letter, dated as of the date of
     effectiveness of the Shelf Registration Statement from the Company's
     independent accountants, in the customary form and covering matters of the
     type customarily covered in comfort letters to underwriters in connection
     with underwritten offerings, and affirming the matters set forth in the
     comfort letters delivered pursuant to Section 9(g) of the Purchase
     Agreement; and

                    (B) deliver such other documents and certificates as may be
          reasonably requested by the Holders and underwriters, if any, to
          evidence compliance with the matters set forth in clause (A) above and
          with any customary conditions contained in any agreement entered into
          by the Company pursuant to this clause (m);

              (xv) prior to any public offering of Transfer Restricted
     Securities, cooperate with the Holders, underwriters, if any, and their
     respective counsel in connection with the registration and qualification of
     the Transfer Restricted Securities under the securities or Blue Sky laws of
     such jurisdictions as such persons may request and do any and all other
     acts or things necessary or advisable to enable the disposition in such
     jurisdictions of the Transfer Restricted Securities covered by the
     applicable Registration Statement; provided, however, that the Company
     shall not be required to register or qualify as a foreign corporation where
     it is not now so qualified or to take any action that would subject it to
     the service of process in suits or to taxation, other than as to matters
     and transactions relating to the Shelf Registration Statement, in any
     jurisdiction where it is not now so subject;

              (xvi)  in connection with any sale of Transfer Restricted
     Securities that will result in such securities no longer being 

                                       11
<PAGE>
 
     Transfer Restricted Securities, cooperate with the Holders to facilitate
     the timely preparation and delivery of certificates representing Transfer
     Restricted Securities to be sold and not bearing any restrictive legends;
     and to register such Transfer Restricted Securities in such denomina tions
     and such names as the Holders may request at least two Business Days prior
     to settlement of such sale of Transfer Restricted Securities;

              (xvii)  (A) list all Shares of Common Stock covered by such Shelf
     Registration Statement on any securities exchange on which the Common Stock
     is then listed or (B) authorize for quotation on the National Association
     of Securities Dealers Automated Quotation System ("NASDAQ") or the National
     Market System of NASDAQ all Shares of Common Stock covered by such Shelf
     Registration Statement if the Common Stock is then so authorized for
     quotation.

              (xviii)  use its best efforts to cause the disposition of the
     Transfer Restricted Securities covered by the Shelf Registration Statement
     to be registered with or approved by such other governmental agencies or
     authorities as may be necessary to enable the seller or sellers thereof to
     consummate the disposition of such Transfer Restricted Securities,
     subject to the proviso contained in clause (xiv) above;

              (xix)  provide a CUSIP number for all Transfer Restricted
     Securities not later than the effective date of a Shelf Registration
     Statement covering such Transfer Restricted Securities and provide the
     transfer agent with printed certificates for the Transfer Restricted
     Securities which are in a form eligible for deposit with the Depository
     Trust Company;
 
              (xx) otherwise use its best efforts to comply with all applicable
     rules and regulations of the Commission, and make generally available to
     its security holders with regard to any applicable Registration Statement,
     as soon as practicable, a consolidated earnings statement meeting the
     requirements of Rule 158 (which need not be audited) covering a twelve-
     month period beginning after the effective date of the Registration
     Statement (as such term is defined in paragraph (c) of Rule 158 under the
     Act);

              (xxi)  if underwritten, make appropriate officers of the Company
     available to the underwriters for meetings with prospective purchasers of
     the Transfer Restricted Securities and prepare and present to potential
     investors customary "road show" 

                                       12
<PAGE>
 
     material in a manner consistent with other new issuances of other
     securities similar to the Transfer Restricted Securities; and

              (xxii)  provide promptly to each Holder upon request each document
     filed with the Commission pursuant to the requirements of Section 13 or
     Section 15(d) of the Exchange Act.

       (b) Restrictions on Holders.  Each Holder agrees by acquisition of a
           -----------------------                                          
Transfer Restricted Security that, upon receipt of the notice referred to in
Section 5(a)(v)(C) or any notice from the Company of the existence of any fact
of the kind described in Section 5(a)(v)(D) hereof (in each case, a "SUSPENSION
                                                                     ----------
NOTICE"), such Holder will forthwith discontinue disposition of Transfer
------                                                                  
Restricted Securities pursuant to the applicable Registration Statement until
(i) such Holder's has received copies of the supplemented or amended Prospectus
contemplated by Section 5(a)(vi) hereof, or (ii) such Holder is advised in
writing by the Company that the use of the Prospectus may be resumed, and has
received copies of any additional or supplemental filings that are
incorporated by reference in the Prospectus (in each case, the "RECOMMENCEMENT
                                                                --------------
DATE").  Each Holder receiving a Suspension Notice hereby agrees that it will
----                                                     
either (i) destroy any Prospectuses, other than permanent file copies, then in
such Holder's possession which have been replaced by the Company with more
recently dated Prospectuses or (ii) deliver to the Company (at the Company's
expense) all copies, other than permanent file copies, then in such Holder's
possession of the Prospectus covering such Transfer Restricted Securities that
was current at the time of receipt of the Suspension Notice. The time period
regarding the effectiveness of the Shelf Registration Statement set forth in
Section 3 hereof, shall be extended by a number of days equal to the number of
days in the period from and including the date of delivery of the Suspension
Notice to the Recommencement Date.

       SECTION 6.   REGISTRATION EXPENSES

          (a) All expenses incident to the Company's performance of or
compliance with this Agreement will be borne by the Company, regardless of
whether a Shelf Registration Statement required by this Agreement becomes
effective, including without limitation: (i) all registration and filing fees
and expenses; (ii) all fees and expenses of compliance with federal securities
and state Blue Sky or securities laws; (iii) all expenses of printing
(including printing certificates for the Common Stock to be issued upon
conversion of the Depositary Shares or Preferred Stock and printing of
Prospectuses), messenger and delivery services and telephone; (iv) all fees and
disbursements of counsel for the Company; (v) all application and filing fees in
connection with listing the Common Stock on a national securities exchange or
automated quotation system pursuant to the requirements hereof; and (vi) all
fees and disbursements of independent certified public accountants of the
Company (including the expenses of any special audit and comfort letters
required by or incident to such performance).

                                       13
<PAGE>
 
          The Company will, in any event, bear its internal expenses (including,
without limitation, all salaries and expenses of its officers and employees
performing legal or accounting duties), the expenses of any annual audit and the
fees and expenses of any person, including special experts, retained by the
Company.

       SECTION 7.   INDEMNIFICATION

          (a) The Company agrees to indemnify and hold harmless each Holder, its
directors, its officers and each person, if any, who controls such Holder
(within the meaning of Section 15 of the Act and Section 20 of the Exchange
Act), from and against any and all losses, claims, damages, liabilities,
judgments, (including without limitation, any legal or other expenses incurred
in connection with investigating or defending any matter, including any action
that could give rise to any such losses, claims, damages, liabilities or
judgments) caused by any untrue statement or alleged untrue statement of a
material fact contained in any Shelf Registration Statement, preliminary
prospectus or Prospectus (or any amendment or supplement thereto) provided by
the Company to any Holder or any prospective purchaser of registered Depositary
Shares or Preferred Stock or registered shares of Common Stock or caused by any
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not mislead ing,
except insofar as such losses, claims, damages, liabilities or judgments are
caused by an untrue statement or omission or alleged untrue statement or
omission that is based upon information relating to any of the Holders furnished
in writing to the Company by any of the Holders.

          (b) Each Holder of Transfer Restricted Securities agrees, severally
and not jointly, to indemnify and hold harmless the Company and its directors
and officers, and each person, if any, who controls (within the meaning of
Section 15 of the Act or Section 20 of the Exchange Act) the Company, to the
same extent as the foregoing indemnity from the Company set forth in Section
7(a) above, but only with reference to information relating to such Holder
furnished in writing to the Company by such Holder expressly for use in any
Registration Statement.  In no event shall any Holder, its directors, its
officers or any person, if any, who controls such Holder be liable or
responsible for any amount in excess of the amount by which the total amount
received by such Holder with respect to its sale of Transfer Re  stricted
Securities pursuant to a Shelf Registration Statement exceeds (i) the amount
paid by such Holder for such Transfer Restricted Securities and (ii) the amount
of any damages that such Holder, its directors, its officers or any person, if
any, who controls such Holder has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission.

          (c) In case any action shall be commenced involving any person in
respect of which indemnity may be sought pursuant to Section 7(a) or 7(b) (the
"INDEMNIFIED PARTY"), the indemnified party shall promptly notify the person
------------------                                                          

                                       14
<PAGE>
 
against whom such indemnity may be sought (the "INDEMNIFYING PARTY") in writing
                                                ------------------             
and the indemnifying party shall assume the defense of such action, including
the employment of counsel reasonably satisfactory to the indemnified party and
the payment of all fees and expenses of such counsel, as incurred (except that
in the case of any action in respect of which indemnity may be sought pursuant
to both Sections 7(a) and 7(b), a Holder shall not be required to assume the
defense of such action pursuant to this Section 7(c), but may employ separate
counsel and participate in the defense thereof, but the fees and expenses of
such counsel, except as provided below, shall be at the expense of the Holder).
Any indemnified party 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 the indemnified party unless (i) the
employment of such counsel shall have been specifically authorized in writing by
the indemnifying party, (ii) the indemnifying party shall have failed to assume
the defense of such action or employ counsel reasonably satisfactory to the
indemnified party or (iii) the named parties to any such action (including any
impleaded parties) include both the indemnified party and the indemnifying
party, and the indemnified party shall have been advised by such counsel that
there may be one or more legal defenses available to it which are different from
or additional to those available to the indemnifying party (in which case the
indemnifying party shall not have the right to assume the defense of such action
on behalf of the indemnified party). In any such case, the indemnifying party
shall not, in connection with any one 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 indemnified parties and all such fees and expenses shall be reimbursed as
they are incurred. Such firm shall be designated in writing by a majority of the
Holders, in the case of the parties indemnified pursuant to Section 7(a), and by
the Company, in the case of parties indemnified pursuant to Section 7(b). The
indemnifying party shall indemnify and hold harmless the indemnified party from
and against any and all losses, claims, damages, liabilities and judgments by
reason of any settlement of any action (i) effected with its written consent or
(ii) effected without its written consent if the settlement is entered into more
than twenty business days after the indemnifying party shall have received a
request from the indemnified party for reimbursement for the fees and expenses
of counsel (in any case where such fees and expenses are at the expense of the
indemnifying party) and, prior to the date of such settlement, the indemnifying
party shall have failed to comply with such reimbursement request. No
indemnifying party shall, without the prior written consent of the indemnified
party, effect any settlement or compromise of, or consent to the entry of
judgment with respect to, any pending or threatened action in respect of which
the indemnified party is or could have been a party and indemnity or
contribution may be or could have been sought hereunder by the indemnified
party, unless such settlement, compromise or judgment (i) includes an
unconditional release of the indemnified party from all liability on claims that
are or could have been the subject matter of such action and (ii) does not
include a statement 

                                       15
<PAGE>
 
as to or an admission of fault, culpability or a failure to act, by or on behalf
of the indemnified party.

          (d) To the extent that the indemnification provided for in this
Section 7 is unavailable to an indemnified party in respect of any losses,
claims, damages, liabilities 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 or judgments (i) in such proportion
as is appropriate to reflect the relative benefits received by the Company, on
the one hand, and the Holders, on the other hand, from their sale of Transfer
Restricted Securities or (ii) if the allocation provided by clause 7(d)(i) is
not permitted by applicable law, in such proportion as is appropri  ate to
reflect not only the relative benefits referred to in clause 7(d)(i) above but
also the relative fault of the Company on the one hand, and of the Holders, on
the other hand, in connection with the statements or omissions which resulted in
such losses, claims, damages, liabilities or judgments, as well as any other
relevant equitable considerations.  The relative fault of the Company, on the
one hand, and of the Holders, on the other hand, shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company, on the one hand, or by the
Holders, on the other hand, and the parties' relative intent, knowledge, access
to information and opportunity to correct or prevent such statement or omission.

          The Company and each Holder agree that it would not be just and
equitable if contribution pursuant to this Section 7(d) were determined by pro
rata allocation (even if the Holders 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 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 incurred by such indemnified party in
connection with investigating or defending any matter, including any action that
could have given rise to such losses, claims, damages, liabilities or judgments.
Notwithstanding the provisions of this Section 7, no Holder or its related
indemnified parties shall be required to contribute, in the aggregate, any
amount in excess of the amount by which the total received by such Holder with
respect to the sale of its Transfer Restricted Securities pursuant to a
Registration Statement exceeds (i) the amount paid by such Holder for such
Transfer Restricted Securities and (ii) the amount of any damages which such
Holder 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 Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.  The Holders' obligations to contribute pursuant
to this Section 7(d) are several in proportion to the 

                                       16
<PAGE>
 
respective number of shares of Transfer Restricted Securities held by each of
the Holders hereunder and not joint.

       SECTION 8.   RULE 144A AND RULE 144

       The Company agrees with each Holder, for so long as any Transfer
Restricted Securities remain outstanding and during any period in which the
Company (i) is not subject to Section 13 or 15(d) of the Exchange Act, to make
available, upon request of any Holder of Transfer Restricted Securities, to any
Holder or beneficial owner of Transfer Restricted Securities in connection with
any sale thereof and any prospective purchaser of Transfer Restricted Securities
designated by such Holder or beneficial owner, the information required by Rule
144(d)(4) under the Act in order to permit resales of such Transfer Restricted
Securities pursuant to Rule 144A, and (ii) is subject to Section 13 or 15(d) of
the Exchange Act, to make all filings required thereby in a timely manner in
order to permit resales of such Transfer Restricted Securities pursuant to Rule
144.

       SECTION 9.   UNDERWRITTEN REGISTRATIONS

          (a) If any of the Transfer Restricted Securities covered by any 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 selected by the Holders of a majority in amount
of such Transfer Restricted Securities included in such offering, subject to the
consent of the Company (which will not be unreasonably withheld or delayed).

          No Holder of Transfer Restricted Securities may participate in any
underwritten registration hereunder unless such Holder (i) agrees to sell its
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 and other documents required
under the terms of such underwriting arrangements.

          (b) Each Holder of Transfer Restricted Securities agrees, if requested
(pursuant to a timely written notice) by the managing underwriters in an
underwritten offering made pursuant to a Shelf Registration Statement, not to
effect any private sale or distribution (including a sale pursuant to Rule
144(k) and Rule 144A, but excluding non-public sales to any of its affiliates,
officers, directors, employees and controlling persons) of any of Depositary
Shares or shares of Preferred Stock in the case of an underwritten offering of
Depositary Shares or shares of Preferred Stock, or any shares of Common Stock,
in the case of an underwritten offering of shares of Common Stock constituting
Transfer Restricted Securities, during the period beginning 10 days prior to,
and ending 90 days after, the closing date of such underwritten offering.

                                       17
<PAGE>
 
          The foregoing provisions of Section 9(b) shall not apply to any Holder
of Transfer Restricted Securities if such Holder is prevented by applicable
statute or regulation from entering into any such agreement.

          (c) If any of the Transfer Restricted Securities covered by any Shelf
Registration are to be sold in an underwritten offering, the underwriters, their
controlling persons and their respective officers, directors, employees,
represen  tatives and agents shall be entitled to indemnity (substantially
similar to the indemnity set forth in Section 7 of the Agreement) from the
Company and the Holders, which indemnity may be set forth in an underwriting
agreement.

       SECTION 10.  MISCELLANEOUS

          (a) Remedies.  The Company acknowledges and agrees that any failure by
              --------                                                          
the Company to comply with its obligations under Section 3 hereof may result in
material irreparable injury to the Initial Purchasers or the Holders for which
there is no adequate remedy at law, that it will not be possible to measure
damages for such injuries precisely and that, in the event of any such failure,
the Initial Purchasers or any Holder may obtain such relief as may be required
to specifically enforce the Company's  obligations under Section 3 hereof.  The
Company further agrees to waive the defense in any action for specific
performance that a remedy at law would be adequate.

          (b) No Inconsistent Agreements.  The Company will not, on or after the
              --------------------------                                        
date of this Agreement, 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 has not previously
entered into any agreement (which has not expired or been terminated) granting
any registration rights with respect to its securities to any person, except for
the parties set forth in Schedule E to the Purchase Agreement.  The Company
agrees to use its best efforts to obtain consent from these parties not to
exercise their right to require the Company to include their securities with the
Shares registered pursuant to any Shelf Registration Statement.  The rights
