       This Amendment No. 2 amends and supplements the Schedule 13D, dated June
25, 1996, as amended by Amendment No. 1, dated August 15, 1996, by Apollo Real
Estate Investment Fund II, L.P., a Delaware limited partnership ("AREIF II"),
and Apollo Real Estate Advisors II, L.P., a Delaware limited partnership ("AREA
II").  

Item 2.
- -------

       The first paragraph of Item 2 is hereby amended to add AP-KEI Holdings,
LLC, a Delaware limited liability company ("AP-KEI"), as a reporting person
(together with AREIF II and AREA II, the "Reporting Persons").

       The following are hereby inserted as the fifth and sixth paragraphs of
Item 2:

               AP-KEI is principally engaged in the business of investment in
real estate and real estate-related interests. The address of AP-KEI's principal
business and its principal office is c/o Apollo Real Estate Advisors II, L.P.,
Two Manhattanville Road, Purchase, New York 10577.

               The managing member of AP-KEI is AP-MM KEI Holdings, LLC, a
Delaware limited liability company ("AP-MM"). AP-MM is principally engaged in
the business of serving as managing member of AP-KEI. The managing member of AP-
MM is Kronus Property, Inc., a Delaware corporation and wholly-owned subsidiary
of AREIF II.


Item 3.  Source and Amount of Funds or Other Consideration.
- -------  ------------------------------------------------- 

       The first paragraph of Item 3 is hereby amended and restated in its
entirety by the following:

               As of the date hereof, the Reporting Persons are deemed to
       beneficially own 4,713,598 shares of Common Stock. Of that amount, 
       AREIF II owns directly 582,956 shares of Common Stock, has options 
       to purchase 1,130,642 additional shares of Common Stock and 
       indirectly owns, through AP-KEI, 3,000,000 additional shares of 
       Common Stock. AP-KEI owns directly 3,000,000 shares of Common 
       Stock. The source of all funds used to acquire beneficial ownership 
       of such shares of Common Stock was investment funds from working 
       capital of AREIF II and AP-KEI. None of the funds used to acquire 
       beneficial ownership were borrowed funds or otherwise obtained
       for the purpose of acquiring the Common Stock. AREA II, the general
       partner of AREIF II, is deemed to beneficially own the shares of 
       Common Stock beneficially owned by AREIF II. The shares of Common 
       Stock beneficially owned by the Reporting Persons were acquired as 
       described below.

       
       The following is inserted at the end of Item 3:

               AP-KEI entered into a Stock Purchase Agreement, dated 
October 10, 1996 (the "October Stock Purchase Agreement"), by and between AP-KEI
and the Company. Pursuant to the October Stock Purchase Agreement, AP-KEI
purchased from the Company 3,000,000 shares 

                              Page 5 of 10 Pages
<PAGE>
 
of Common Stock at a price of $14.50 per share for an aggregate cash purchase
price of $43,500,000.

               The discussion herein of the October Stock Purchase Agreement is
subject to and qualified in its entirety by reference to such agreement, a copy
of which is attached hereto as an exhibit and incorporated herein by reference.

Item 4.
- -------

               Item 4 is hereby amended by adding to the end thereof the
following:

               In connection with the execution of the October Stock Purchase
       Agreement, AP-KEI acquired a significant equity interest in the Company
       for the purpose of investment. Pursuant to the October Stock Purchase
       Agreement, the Company (a) expanded the Board of Directors of the Company
       (the "Board") from eight to twelve directors and included among the four
       additional directors three designees of AP-KEI and its indirect parent,
       AREIF II, and (b) agreed to certain provisions that relate to certain
       matters identified in paragraphs (a) through (j) of Item 4 of Schedule
       13D. For a description of the October Stock Purchase Agreement and such
       provisions, see Item 6. Except as contemplated by the October Stock
       Purchase Agreement, the Reporting Persons have no present plans or
       proposals relating to or that would result in any of the matters
       identified in paragraphs (a) through (j) of Item 4 of Schedule 13D. 
       The Reporting Persons have and will, on an on-going basis, continue to
       evaluate their investment in the Company and reserve the right to
       propose, seek to take, or take actions which relate to or would result in
       the matters referred to in Item 4 of Schedule 13D. In the event of a
       material change in the present plans or intentions of the Reporting
       Persons, the Reporting Persons will amend this Schedule 13D to reflect
       such change.


Item 5.  Interest in Securities of the Issuer.
- -------  ------------------------------------ 

          Paragraphs (a) and (b) of Item 5 are hereby amended and restated in
their entirety by the following:

               (a) and (b)  As of the date hereof, AREIF II, together with AREA
       II, are deemed to beneficially own an aggregate of 4,713,598 shares of
       the Common Stock, which constitutes approximately 22.6% of the Common
       Stock outstanding.* Of that amount, 3,000,000 shares of Common Stock
       are also beneficially owned by AP-KEI (a subsidiary of AREIF II), which
       constitutes approximately 14.4% of the Common Stock outstanding.

- ------------------------
*      All calculations of percentages of beneficial ownership in this Schedule
13D are based on there being 20,873,866 shares of Common Stock outstanding,
which is the amount disclosed in the Company's Quarterly Report on Form 10-Q for
the period ended June 30, 1996 (17,873,866 shares of Common Stock) together with
the 3,000,000 shares of Common Stock issued by the Company pursuant to the
October Stock Purchase Agreement.

               AREIF II owns directly or indirectly (through AP-KEI) 3,582,956
shares of Common Stock, as to which it has sole voting and dispositive power.
AREA II, general partner of AREIF II, is deemed to beneficially own such
3,582,956 shares of Common Stock and have sole voting and dispositive power.

               By the terms of the TCW Option Agreement and the Tyndall Option
Agreement (each of which is attached as an exhibit to the initial Schedule 13D
and incorporated herein by reference), AREIF II has the right to acquire another
1,130,642 shares of Common Stock.
 
               AP-KEI owns 3,000,000 shares of Common Stock, as to which it has
sole voting and dispositive power. AP-MM is the managing member of AP-KEI. The
managing member of AP-MM is Kronus Property, Inc, a wholly-owned subsidiary of
AREIF II.
 
       Item 5(c) is hereby amended to include the following:

               Since the most recent filing on Schedule 13D by the Reporting
       Persons, there have been no transactions in the Common Stock except for
       the October Stock Purchase Agreement, dated October 10, 1996, pursuant to
       which AP-KEI purchased from the Company 3,000,000 shares of Common Stock
       at a price of $14.50 per share for an aggregate cash purchase price of
       $43,500,000.

Item 6.
- -------

       On October 10, 1996, AP-KEI entered into the October Stock Purchase
Agreement and purchased 3,000,000 shares of Common Stock as contemplated
thereby. Pursuant to the October Stock Purchase Agreement, the Company (a)
expanded the Board from eight to twelve directors and included among the four
additional directors three designees of AP-KEI and its indirect parent, AREIF
II, (b) agreed, subject the terms and conditions in the October Stock Purchase
Agreement, to exempt the Reporting Persons and their affiliates from (i) the
Company's Common Stock Rights Agreement, (ii) the "Excess Shares" provision of
the Company's Articles of Incorporation, and (iii) certain Florida statutory
restrictions, and (c) agreed to give AP-KEI preemptive rights with respect to
any new issuance of securities of the Company. Also pursuant to the October
Stock Purchase Agreement, AP-KEI agreed to a three-year standstill (the
"Standstill") during which AP-KEI, AREIF II and certain of their affiliates 
(the "Affiliates") are not permitted to acquire more than 25% of the outstanding
Common Stock, subject to certain exceptions. During the term of the Standstill,
AP-KEI, AREIF II and the Affiliates have agreed to vote all shares of Common
Stock held by them either in accordance with the recommendation of the Board or
proportionately with all other voting shareholders, except in the case of any
proposal before the shareholders to change the Company's status as a real estate
investment trust ("REIT"), amend the organizational documents of the Company or
take any extraordinary corporate action. Any shares of Common Stock beneficially

     2.8.  Corporate Proceedings, etc.
           -------------------------- 

          (a)  The Company has authorized the execution, delivery and
performance of this Agreement and each of the transactions and agreements
contemplated hereby.  No other corporate action (including shareholder approval)
is necessary to authorize such execution, delivery and performance, and upon
such execution and delivery this Agreement, the Registration Rights Agreement
and the Amended Rights Agreement shall constitute the valid and binding
obligations of the Company, enforceable against the Company in accordance with
their terms.  The Company has authorized the issuance and delivery of the Shares
in accordance with this Agreement.

          (b) The Company has duly taken such actions under Florida law so that
the execution and delivery of this Agreement, and the acquisition, from time to
time, by Apollo or its Affiliates of the Permitted Securities shall not be an
"affiliated transaction" under the provisions of  (S)607.0901 of the Florida
Business Corporation Act (the "FBCA") or a "control share acquisition" by Apollo
or its Affiliates under the provisions of (S) 607.0902 of the Florida Business
Corporation Act; provided, however, that: (a) nothing in this Agreement shall
                 --------  -------                                           
preclude the application of either of (S)607.0901 or (S)607.0902 to any other
transaction not expressly permitted under this Agreement, whether involving
Apollo or any of its Affiliates or otherwise; and (b) in the event that Apollo
or any of its Affiliates shall, at any time, be the Beneficial Owner of any
security of the Company, including without limitation, any share of Common
Stock, which is not a Permitted Security (each a "Prohibited Security" and
collectively "Prohibited Securities"), then all Permitted Securities shall be
aggregated with all Prohibited Securities in calculating whether Apollo and its
Affiliates engage or have engaged in an "affiliated transaction" or a "control
share acquisition", as the case may be.  The Company has provided Apollo with a
copy of the resolutions of the Board of Directors of the Company (the "Board of
Directors") that carry out the actions described by this Section 2.8(b).

          (c) The Company has duly amended the Rights Agreement (the "Amended
Rights Agreement") such that the definition of "Exempt Person" thereunder
includes (i) Apollo and its Affiliates so long as neither Apollo nor any of its
Affiliates is the Beneficial Owner of any Prohibited Security and (ii) any
person who is an "Affiliate" (using in this clause (ii) only the term as defined
in the Rights Agreement) of Apollo to the extent that such "Affiliate" would be
an Acquiring Person (as defined in the Rights Agreement) as a result of
"Beneficially Owning" (as defined in the Rights Agreement) any Permitted
Securities; provided, however, that, in the event that Apollo or any Affiliate
            --------  -------                                                 
shall, at any time, Beneficially Own any Prohibited Security, then: (a) nothing
in this Agreement shall preclude the Company from amending and restating the
Rights Agreement in any way or adopting a new rights agreement; and (b) all
Permitted Securities shall be aggregated with all Prohibited Securities in
calculating the number of securities of the Company, including, without

                                      -5-
<PAGE>
 
limitation, Common Stock, of which Apollo and its Affiliates are Beneficial
Owners for purposes of the Rights Agreement.  The Company has provided Apollo
with a copy of the Amended Rights Agreement.

          (d)  The Company has duly taken all such actions under its Amended and
Restated Articles of Incorporation as are necessary such that the Permitted
Securities beneficially owned from time to time by Apollo and its Affiliates
shall not be deemed to be "Excess Shares", as such term is defined therein;
                                                                           
provided, however, that: (a) nothing in this Agreement shall preclude the
- --------  -------                                                        
application of the Excess Share provision of the Amended and Restated Articles
of Incorporation, as in effect on the date hereof or as amended or restated from
time to time (the "Articles"), to any other acquisition of shares of securities
of the Company not expressly permitted under this Agreement, whether by Apollo
or any of its Affiliates or otherwise; and (b) in the event that Apollo or any
of its Affiliates shall, at any time, become the Beneficial Owner of any
Prohibited Security, the Permitted Securities may, to the extent provided in the
Articles, be aggregated with any Prohibited Securities in calculating the number
of shares of securities of the Company, including, without limitation, Common
Stock, for purposes of any calculation under the Articles, including, without
limitation, any so-called Excess Share calculation.  The Company has provided
Apollo with a copy of the resolutions of the Board of Directors that carry out
the actions described by this Section 2.8(d).

     2.9.  Board of Directors
           ------------------

     Effective immediately following the Closing, the Board of Directors of the
Company (the "Board of Directors") consists of twelve (12) directors, including
Messrs. William L. Mack, Lee S. Neibart and W. Edward Scheetz, who have been
duly elected as Disinterested Directors to the Board of Directors by the
affirmative vote of at least seven directors (each named person, together with
any person from time to time designated by Apollo to replace such person,
provided that each such designee is reasonably acceptable to the Board of
- --------

and no Apollo Director shall serve as a director on the Board of Directors until
immediately following the Closing.

     2.10.  Consents and Approvals
            ----------------------

     The execution and delivery by the Company of this Agreement, the
performance by the Company of its obligations hereunder and the consummation by
the Company of the transactions contemplated hereby do not require the Company
or any of its subsidiaries to obtain any consent, approval or action of, or make
any filing with or give any notice to, any corporation, person or firm or any
public, governmental or judicial authority except (a) as set forth in Schedule
                                                                      --------
2.10; and (b) such as have been duly obtained or made, as the case may be,

full force and effect on the Closing Date; and (c) such as would not have a
Material Adverse Effect or an Apollo Material Adverse Effect following the
Closing.

     2.11.  Absence of Defaults, Conflicts, etc.
            ----------------------------------- 

     The execution and delivery of this Agreement does not, and the fulfillment
of the terms hereof by the Company, and the issuance of the Shares will not, (i)
result in a breach of any of the terms, conditions or provisions of, or (ii)
constitute a default under, or (iii) permit the acceleration of rights under or
termination of, any indenture, mortgage, deed of trust, credit agreement, note
or other evidence of indebtedness, or other agreement of the Company or any of
its subsidiaries (collectively the "Agreements and Instruments"), or the
Organizational Documents, or any rule or regulation of any court or federal,
state or foreign regulatory board or body or administrative agency having
jurisdiction over the Company or any of its subsidiaries or over their
respective properties or businesses, which breach, default, acceleration of
rights or termination would have a Material Adverse Effect or an Apollo Material
Adverse Effect following the Closing.  To the Company's knowledge, no event has
occurred and no condition exists which, upon notice or the passage of time (or
both), would constitute a default under any such Agreements and Instruments or
in any license, permit or authorization to which the Company or any subsidiary
is a party or by which any of them may be bound.

     2.12.  Compliance with Law
            -------------------

          (a)  Subject to such matters as are identified in the SEC Reports
relating to governmental rules and regulations promulgated under the Americans
with Disabilities Act and environmental laws, neither the Company nor any of its
subsidiaries nor any property owned by them is in material violation of any
laws, ordinances, governmental rules or regulations to which it is subject,
including without limitation laws or regulations relating to the environment or
to occupational health and safety, and no material expenditures are or will be
required in order to cause its current operations or properties to comply with
any such law, ordinances, governmental rules or regulations.  There is no
continuing order, injunction or decree to which the Company or any of its
subsidiaries is subject or by which any of their assets is bound, and to the
best knowledge of the Company neither the Company nor any of its subsidiaries is
subject to, or the target of, any inquiry or investigation which could result in
any such order, injunction or decree.

          (b)  To the Company's knowledge, the Company and its subsidiaries have
all licenses, permits, franchises or other governmental authorizations necessary
to the ownership of their property or to the conduct of their respective
businesses, which if violated or not obtained might have a Material Adverse
Effect. To the Company's knowledge, neither the Company nor any subsidiary has
been finally denied any application for any such licenses, permits, franchises
or other governmental authorizations necessary to its business.

a "domestically-controlled" REIT within the meaning of the Code Section
897(h)(4)(B), and (ii) non-domestic persons Holding five percent (5%) or more of
the Common Stock are set forth in Schedule 2.13.  To the Company's knowledge,
                                  -------------

treated as an "individual" for purposes of Section 542(a)(2) of the Code (as
modified by Section 856(h) of the Code) owns or would be considered to own

Code, as modified by Section 856(h) of the Code) in excess of 9.8% of the value
of the outstanding equity interest in the Company.

          (b)  (i)  The Company was eligible to and did validly elect to be
taxed as a real estate investment trust ("REIT") for federal income tax purposes

time.  The Company has met all requirements necessary to be treated as a REIT
for purposes of the income tax provisions of each of the states in which it owns
property or conducts business (to the extent any such state recognizes REIT
status).  Each subsidiary of the Company is a Qualified REIT Subsidiary as
defined in Section 856(i) of the Code.  Each subsidiary of the Company organized
as a partnership (and any other subsidiary that files tax returns as a
partnership for federal income tax purposes) was and continues to be classified
as a partnership for federal income tax purposes.

               (ii)  The Company has operated, and intends to continue to
operate, in such a manner as to qualify as a REIT for 1996.

               (iii) The Company has not taken or omitted to take any action

the Company's status as a REIT is pending or, to the Company's knowledge,
threatened.

the Company, threatened, against the Company or its subsidiaries, or any of
their respective properties or assets, by or before any court, arbitrator or

properties requires such qualification, except where the failure to so qualify

the Disinterested Directors to elect or designate an individual designated by
Apollo to fill any vacancy created by the death, disability, retirement,
resignation or removal of any Apollo Director, provided that each such designee
                                               --------                        
is reasonably acceptable to the Board of Directors.

          (e)  The Company will establish and maintain executive, finance, audit
and compensation committees of the Board of Directors, and shall use its best
efforts to elect, appoint or designate to each of such committees and to any
other committees maintained by the Company that number of Apollo Directors that
gives the Apollo Directors the same proportional representation on any such
committee as they otherwise have on the Board of

                                      -12-
<PAGE>
 
Directors (but in no case less than one Apollo Director).  Notwithstanding the
foregoing, no Apollo Director shall be elected, appointed or designated to an
independent committee of the Board of Directors established for the purpose of
reviewing (i) a material proposed transaction between the Company and Apollo or
any of its Affiliates or Associates or (ii) compliance by the Company or Apollo
or any of its Affiliates with the terms of this Agreement (an "Independent
Committee").

     4.3. Takeover Defenses
          -----------------

          (a)  So long as Apollo and its Affiliates Beneficially Own only
Permitted Securities, the Company shall take all such further actions under
Florida law as are necessary such that Sections 607.0901 and 607.0902 of the
Florida Business Corporation Act (or their successor provisions) relating to
affiliated transactions and control share acquisitions shall not apply to Apollo
and its Affiliates or the Company as a result of either the acquisition or
ownership by Apollo or its Affiliates of any Permitted Securities; provided,
                                                                   -------- 
however, that: (a) nothing in this Agreement shall cause the Company to take any
- -------                                                                         
such actions to preclude the application of either of (S)607.0901 or (S)607.0902
to any other transaction not expressly permitted under this Agreement, whether
involving Apollo or its Affiliates or otherwise; and (b) in the event that
Apollo or any of its Affiliates shall, at any time, become the Beneficial Owner
of a Prohibited Security, then all Permitted Securities shall be aggregated with
all Prohibited Securities in calculating whether Apollo or its Affiliates engage
or have engaged in an "affiliated transaction" or a "control share acquisition",
as the case may be.

          (b)  So long as Apollo and its Affiliates Beneficially Own only
Permitted Securities, the Company will not, without the prior written consent of
Apollo, amend the Rights Agreement or adopt any new rights agreement; provided,
                                                                      -------- 
however, that: (a) nothing in this Agreement shall prevent the Company from
- -------                                                                    
extending the expiration date of Rights granted under the Rights Agreement; and
(b) in the event that Apollo or any of its Affiliates shall, at any time, become
the Beneficial Owner of a Prohibited Security, then all Permitted Securities
shall be aggregated with all Prohibited Shares in calculating the number of
shares of securities of the Company, including, without limitation, Common
Stock, of which Apollo and its Affiliates are Beneficial Owners for purposes of
the Rights Agreement.

          (c)  So long as Apollo and its Affiliates Beneficially Own only
Permitted Securities, the Company will not, without the prior written consent of
Apollo, take, or fail to take, any action that causes any Permitted Securities
to be deemed "Excess Shares" under the Articles; provided, however, that (a)
                                                 --------  -------          
nothing in this Agreement shall require the Company to take any such actions to
preclude the application of the Excess Share provision of the Articles to any
other transaction not expressly permitted under this Agreement, whether
involving Apollo or its Affiliates  or otherwise; and (b) in the event that
Apollo shall, at any time, become the beneficial owner of any Prohibited
Security, then the Permitted Securities may, to the extent provided in the
Articles, be aggregated with any Prohibited Securities in calculating

                                      -13-
<PAGE>
 
the number of shares of securities of the Company, including, without
limitation, Common Stock for purposes of any calculation under the Articles,
including, without limitation, a so-called Excess Share calculation.

     4.4.  Subscription Right
           ------------------

     If at any time during the term of this Agreement the Company issues equity
securities of any kind (the term "equity securities" shall include for these
purposes Common Stock and any warrants, options or other rights to acquire
equity securities (including Common Stock) and debt securities convertible into
equity securities) of the Company (other than the issuance of (a) securities
pursuant to the acquisition of another corporation by the Company by merger,
purchase of substantially all of the assets or other form of reorganization, (b)
shares of Common Stock issued pursuant to the Rights Agreement, to the extent
that Apollo is expressly excluded from receiving such shares by the terms of the
Rights Agreement, (c) Common Stock (or options or warrants to acquire Common
Stock) pursuant to an employee stock option plan, stock bonus plan, stock
purchase plan, stock investment plan, benefit plan or other management or
director equity program approved by the Board of Directors or (d) Common Stock
issued as a result of the exercise of warrants outstanding on the Closing Date),
then, as to Apollo, the Company shall, no later than the date of any such
issuance:

          (i)  give written notice setting forth in reasonable detail (A) the
designation and all of the terms and provisions of the securities to be issued
(the "New Securities"), including, where applicable, the voting powers,
preferences and relative participating, optional or other special rights, and
the qualification, limitations or restrictions thereof and interest rate and
maturity; (B) the price and other terms of the sale of such securities; (C) the
amount of such securities to be issued; and (D) such other information as Apollo
may reasonably request within ten (10) Business Days of such notice in order to
evaluate the issuance; and

          (ii)  offer to sell to Apollo on the terms and at such price as set
forth in the notice required by clause (i) of this Section 4.4 that number of
additional New Securities that would cause Apollo and its Affiliates to
Beneficially Own (A) in the case of New Securities consisting of Common Stock or
securities exercisable into, exchangeable for or convertible into Common Stock,
25% of the sum of (1) the number of shares of Common Stock outstanding on such
date and (2) if applicable, the number of shares of Common Stock issuable upon
the exercise, exchange or conversion of such New Securities, and (B) in the case
of New Securities consisting of any other equity security, 25% of the number of
New Securities outstanding.

     Apollo shall be entitled to exercise its purchase rights hereunder at any
time on or prior to the later to occur of (A) ten (10) Business Days after
receipt of such notice from the Company or (B) ten (10) Business Days after
Apollo has received any information requested by it pursuant to Section
4.4(i)(D) that is reasonably accessible to the Company.  If Apollo shall not
have exercised its purchase rights within the applicable ten (10) Business Day
period,

                                      -14-
<PAGE>
 
Apollo will be deemed to have forfeited such rights with respect to such
issuance of New Securities, provided, however, that the election by Apollo not
                            --------  -------                                 
to exercise its subscription rights under this Section 4.4 in any one instance
shall not affect its right as to any subsequent issuance.

     4.5.  Termination of Company Covenants
           --------------------------------

     In addition to such remedies as the Company may otherwise have under this
Agreement or in law or equity, the obligations of the Company under Sections 4.2
and 4.4 shall cease in the event that Apollo or any Affiliate shall breach its
obligations under any of Sections 5.1(a), 5.1(b), 5.1(d), 5.2, 5.4, 5.5 or
5.6(a).

shares of Common Stock resulting from the exercise of the Options.

          (c)  Apollo further agrees that if Apollo or its Affiliates intend or

writing of such intention or proposal at least three (3) Business Days prior to
making any such purchase and (ii) discuss with the Company during such three (3)
Business Day period the possibility of purchasing such additional shares
directly from the Company.

          (d)  Apollo and its Affiliates agree to vote all shares of Common
Stock Beneficially Owned by any of them (i) in accordance with the
recommendation of the Board of Directors or (ii) proportionately with all other
voting shareholders, provided, however, that Apollo and its Affiliates may vote

or (B) a Schedule 14D-1 announcing a tender offer for Common Stock or rights to
acquire shares of Common Stock or securities convertible into shares of Common
Stock in an amount which, together with the shares of Common Stock then owned by
such person, would result in such person Holding 15% or more of the Common Stock

available takeover defense with respect to such person; or

          (iii)  Amendment of Organizational Documents -- without the prior

     5.3.  Resale of Securities
           --------------------

     Apollo covenants that it will not sell or otherwise transfer the Shares
except pursuant to an effective registration under the Securities Act or in a
transaction which, in the opinion of counsel reasonably satisfactory to the
Company, qualifies as an exempt transaction under the Securities Act and the
rules and regulations promulgated thereunder.

     The certificates evidencing the Shares will bear the following legend
reflecting the foregoing restrictions on the transfer of such securities:

     "The securities evidenced hereby have not been registered under the
     Securities Act of 1933, as amended (the "Act"), and may not be transferred
     except pursuant to an effective registration under the Act or in a
     transaction which, in the opinion of counsel reasonably satisfactory to the
     Company, qualifies as an exempt transaction under the Act and the rules and
     regulations promulgated thereunder."

     5.4.  Consent Solicitation
           --------------------

     If the Standstill Agreements are in effect at the time of the Company's
1999 Annual Meeting of Shareholders (which meeting shall be held in the year
1999), Apollo and its Affiliates shall vote all of their shares of Common Stock
in favor of any proposal of the Board of Directors to amend the Organizational
Documents to limit or eliminate the ability of shareholders of the Company to
act by written consent in lieu of a shareholder meeting.

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

          (a)  For so long as the Standstill Agreements are in effect, Apollo
and its Affiliates shall Beneficially Own only Permitted Securities and shall
not Beneficially Own any share of Common Stock which is a Prohibited Security.
If Apollo or any Affiliate becomes aware of the Beneficial Ownership by an
Associate of Apollo or an Associate of an Affiliate of Apollo of securities of
the Company, Apollo shall report such Beneficial Ownership to the Company within
five (5) business days of the time that Apollo or such Affiliate had knowledge
of such Beneficial Ownership.  In addition, Apollo and its Affiliates shall
provide such other and further information as the Company may reasonably request
so that the Company can determine whether such Associate is an Affiliate of
Apollo or any Affiliate of Apollo or whether Apollo or any Affiliate Beneficial
Owns securities of the Company Beneficially Owned by such Associate.

                                      -18-

          (b)  To the extent that Permitted Securities Held by Apollo and its
Affiliates may include, from time to time, and for any reason (including,
without limitation, the exercise, exchange, or conversion of New Securities or
the Beneficial Ownership of Inadvertent Shares), shares of Common Stock or other
voting securities of the Company which are entitled to more than twenty-five
(25%) percent (the "Voting Limit") of the voting rights of any class of voting
securities of the Company, then Apollo and its Affiliates shall vote, or cause
to be voted, that number of such voting securities equal to the difference
between (x) the Voting Limit and (y) the number of shares of voting securities
Beneficially Owned by Apollo and its Affiliates in such class proportionately
with the vote of all other voting holders of the voting securities in such
class, excluding Apollo and its Affiliates.

          (c)  Any Permitted Assignee agrees to vote all of its shares of Common
Stock (i) in accordance with the recommendation of the Board of Directors or
(ii) proportionately with all other voting shareholders, provided, however, that
                                                         --------  -------      
such Permitted Assignee may vote its shares without restriction in connection

to Section 5.4), and (z) any Extraordinary Transaction.

          (b)  Upon the occurrence and during the continuance of any breach of a
covenant by a party to this Agreement, the nonbreaching party shall provide the

termination of this Agreement upon any grounds or in any circumstances addressed

2.  Registration Rights.
    ------------------- 

     2.1.  Demand Registration.
           ------------------- 

          (a)  At any time after October 10, 1997, if the Company shall receive
     a written request from the Apollo Holders of at least 50% of the Apollo
     Registrable Securities then outstanding and entitled to registration rights
     under this Section 2 (the "Initiating Apollo Holders") that the Company
                                -------------------------                   
     effect the registration under the 1933 Act of a number of Apollo
     Registrable Securities constituting at least 500,000 shares of Common
     Stock, then the Company shall, within five days of the receipt thereof,
     give written notice of such request to all Holders and shall, subject to
     the limitations of this Section 2.1, use its best efforts to effect such a
     registration as soon as practicable and in any event to file within 75 days
     of the receipt of such request a registration statement under the 1933 Act
     covering all the Registrable Securities which the Holders shall in writing
     request (within 10 days of receipt of the notice given by the Company
     pursuant to this Section 2.1(a)) to be included in such registration and to
     use its reasonable best efforts to have such registration statement become
     effective within 120 days after receipt of such request.

          (b)  If the Initiating Apollo Holders intend to distribute the
     Registrable Securities covered by their request by means of an
     underwriting, they shall so advise the Company as part of their request
     made pursuant to this Section 2.1 and the Company shall include such
     information in the written notice referred to in Section 2.1(a).  In such
     event, the right of any Holder to include its Registrable Securities in
     such registration shall be conditioned upon such Holder's participation in
     such underwriting and the inclusion of such Holder's Registrable Securities
     in the underwriting (unless otherwise mutually agreed by a majority in
     interest of the Initiating Apollo Holders and such Holder) to the extent
     provided herein.  All Holders proposing to distribute their securities
     through such underwriting shall (together with the Company as provided in
     Section 2.3(d)) enter into an underwriting agreement in customary form with
     the underwriter or underwriters selected for such underwriting by a
     majority in interest of the Initiating Apollo Holders.  The Initiating
     Apollo Holders shall consult with the Board of Directors regarding the
     selection of an underwriter or underwriters, but approval by the Board of
     Directors of any underwriter selected by the Initiating Apollo Holders
     shall not be required. Notwithstanding any other provision of this Section
     2.1, if, in the case of a registration requested pursuant to Section
     2.1(a), the underwriter advises the Initiating Apollo Holders in writing
     that marketing factors require a limitation of the number of shares to be
     underwritten, then the Initiating

                                      -4-
<PAGE>
 
     Apollo Holders shall so advise the Company and all Holders of Registrable
     Securities which would otherwise be underwritten pursuant hereto, and all
     securities other than Registrable Securities sought to be included in the
     underwriting shall first be excluded. To the extent that further limitation
     is required, the number of Registrable Securities that may be included in
     the underwriting shall be allocated pro rata among all Holders desiring to
     participate in such underwriting (according to the number of Registrable
     Securities then held by each such Holder).  No Registrable Securities
     requested by any Holder to be included in a registration pursuant to
     Section 2.1(a) shall be excluded from the underwriting unless all
     securities other than Registrable Securities are first excluded.

          (c)  Notwithstanding the foregoing provisions of this Section 2.1, in
     the event that the Company is requested to file any registration statement
     pursuant to this Section 2.1:

               (i)  the Company shall not be obligated to effect the filing of
          such registration statement during the six months following the
          effective date of any other registration statement pertaining to an
          underwritten public offering of securities for the account of the
          Company; and

               (ii)  if the Company shall furnish to the Holders requesting such
          registration statement a certificate signed by the president of the
          Company (A) stating that, in the good faith judgment of a majority of
          the disinterested members of the Board of Directors, (1) an
          undisclosed material event (x) has occurred and is continuing or (y)
          is likely to occur within 90 days and (2) the disclosure of such
          undisclosed material event would have a material adverse effect on the
          Company or on a proposed material transaction involving the Company or
          a substantial portion of its assets and (B) describing in reasonable
          detail such undisclosed material event, then the Company shall have
          the right to defer such filing for a period of not more than 120 days
          after receipt of the request of the relevant Initiating Apollo
          Holders; provided, however, that the Company may not utilize the right
                   --------  -------                                            
          set forth in this Section 2.1(c)(ii) more than once in any 12-month
          period.
 
     2.2.  Company Registration.  If (but without any obligation to do so) the
           --------------------                                               
Company proposes to register any Common Stock for its own account (including for
this purpose a registration effected by the Company for stockholders other than
the Holders) under the 1933 Act in connection with the public offering of such
Common Stock solely for cash (other than a registration on Form S-8 or a
registration on Form S-4), the Company shall, at such time, promptly give each
Holder written notice of such registration.  Upon the written request of any
Apollo Holder given not later than 10 business days before the anticipated
effective date of such registration (as set forth in such notice by the

best efforts to cause a registration statement covering all

                                      -5-
<PAGE>
 
of the Apollo Registrable Securities that each such Apollo Holder has requested
to be registered to become effective under the 1933 Act.  The Company shall be
under no obligation to complete any offering of securities it proposes to make
and shall incur no liability to any Apollo Holder for its failure to do so.

     2.3.  Obligations of the Company.  Whenever required under this Section 2
           --------------------------                                         
to use its best efforts to effect the registration of any Apollo Registrable
Securities, the Company shall, as expeditiously as reasonably possible, prepare
and file with the SEC a registration statement with respect to such Apollo
Registrable Securities and use its best efforts to cause such registration
statement to become effective, and, upon the request of the Holders of a
majority of the Registrable Securities registered thereunder, keep such
registration statement effective for up to 180 days or until such earlier date
as such Holders have informed the Company in writing that the distribution of
all Registrable Securities registered thereunder has been completed.  In
addition, the Company shall:

          (a)  prepare and file with the SEC such amendments and supplements to
     such registration statement and the prospectus used in connection with such
     registration statement, and use its best efforts to cause each such
     amendment and supplement to become effective, as may be necessary to comply
     with the provisions of the 1933 Act with respect to the disposition of all
     securities covered by such registration statement;

          (b)  furnish to the Apollo Holders such reasonable number of copies of
     a prospectus, including a preliminary prospectus, in conformity with the
     requirements of the 1933 Act, and such other documents as they may
     reasonably request in order to facilitate the disposition of Apollo
     Registrable Securities owned by them;

          (c)  use its best efforts to register or qualify the securities
     covered by such registration statement under such other securities or blue
     sky laws of such states and jurisdictions as shall be reasonably requested
     by the Apollo Holders, except that the Company shall not be required in
     connection therewith or as a condition thereto to qualify to do business or
     file a general consent to service of process in any such state or
     jurisdiction;

          (d)  in the event of any underwritten public offering, enter into and
     perform its obligations under an underwriting agreement, in usual and
     customary form and including representations and warranties by the Company
     relating to the business and properties of the Company, with the managing
     underwriter of such offering and take all actions reasonably requested by
     the managing underwriter of such offering in furtherance of the
     underwriters' selling efforts; provided, however, that each Apollo Holder
                                    --------  -------                         
     participating in such underwriting shall also enter into and perform its
     obligations under such an underwriting agreement, including furnishing any
     opinion of counsel or entering into a lock-up agreement reasonably
     requested by the managing underwriter;

                                      -6-
<PAGE>
 
          (e)  notify each Apollo Holder of Apollo Registrable Securities
     covered by such registration statement, at any time when a prospectus
     relating to Apollo Registrable Securities covered by such registration
     statement is required to be delivered under the 1933 Act, of the happening
     of any event as a result of which the prospectus included in such
     registration statement, as then in effect, includes an untrue statement of
     a material fact or omits to state a material fact required to be stated
     therein or necessary to make the statements therein not misleading in the
     light of the circumstances then existing and promptly file such amendments
     and supplements which may be required pursuant to Section 2.3(a) on account
     of such event and use its best efforts to cause each such amendment and
     supplement to become effective;
 
          (f)  furnish, at the request of any Apollo Holder requesting
     registration of Apollo Registrable Securities pursuant to this Section 2,
     on the date that such Apollo Registrable Securities are delivered to the
     underwriters for sale in connection with a registration pursuant to this
     Section 2, if such securities are being sold through underwriters, or, if
     such securities are not being sold through underwriters, on the date the
     registration statement with respect to such securities became effective,
     (i) an opinion, dated such date, of the counsel representing the Company
     for the purposes of such registration, in form and substance as is
     customarily given by company counsel to the underwriters in an underwritten
     public offering, addressed to the underwriters, if any, and to the Apollo
     Holders requesting registration of Apollo Registrable Securities and (ii) a
     letter dated such date, from the independent certified public accountant of
     the Company, in form and substance as is customarily given by independent
     certified public accountants to underwriters in an underwritten public
     offering, addressed to the underwriters, if any, and to the Apollo Holders
     requesting registration of Apollo Registrable Securities; and

          (g)  apply for listing and use its best efforts to list the Apollo
     Registrable Securities being registered on any national securities exchange
     on which a class of the Company's equity securities are listed or, if the
     Company does not have a class of equity securities listed on a national
     securities exchange, apply for qualification and use its best efforts to
     qualify the Apollo Registrable Securities being registered for inclusion on
     the automated quotation system of the National Association of Securities
     Dealers, Inc.

     2.4.  Furnish Information.  It shall be a condition precedent to the
           -------------------                                           
obligations of the Company to take any action pursuant to this Section 2 in
respect of the Apollo Registrable Securities of any selling Apollo Holder that
such selling Apollo Holder shall furnish to the Company such information
regarding itself, the Apollo Registrable Securities held by it, and the intended
method of disposition of such Apollo Registrable Securities as shall be required
to effect the registration of such Apollo Registrable Securities.

                                      -7-

     2.5.  Expenses of Demand Registration.  All expenses (other than
           -------------------------------                           
underwriting discounts and commissions and fees and expenses of professionals
retained by the Apollo Holders) relating to Apollo Registrable Securities
incurred in connection with each registration, filing or qualification pursuant
to Section 2.1(a) and each registration, filing or qualification pursuant to
Section 2.10, including all registration, filing and qualification fees,
printing and accounting fees, fees and disbursements of counsel for the Company,
shall be borne by the Company; provided, however, that the Company shall not be
                               --------  -------                               
required to pay for any expenses of any registration proceeding begun pursuant
to Section 2.1(a) if the registration request is subsequently withdrawn at any
time at the request of the Holders of a majority of the Registrable Securities
to be registered other than as a result of a material adverse change in the
condition, business or prospects of the Company that was unknown to the Holders
of a majority of such Registrable Securities at the time of their request (in
which case all participating Holders shall bear such expenses).  All
underwriting discounts and commissions relating to Apollo Registrable Securities
included in any registration effected pursuant to Section 2.1(a) or 2.10 will be
borne and paid ratably by the Apollo Holders of such Apollo Registrable
Securities, and, if it participates, the Company.  All fees and expenses of
professionals retained by the Apollo Holders in connection with any registration
of Apollo Registrable Securities effected pursuant to Section 2.1(a) or 2.10
will be borne and paid ratably by the Apollo Holders of such Apollo Registrable
Securities.

     2.6.  Expenses of Company Registration.  The Company shall bear and pay all
           --------------------------------                                     
expenses (other than underwriting discounts and commissions and fees and
expenses of professionals retained by the Apollo Holders) incurred in connection
with any registration, filing or qualification of Apollo Registrable Securities
with respect to any registration pursuant to Section 2.2 for each Apollo Holder,
including all registration, filing and qualification fees, printing and
accounting fees, fees and disbursements of counsel for the Company.  All
underwriting discounts and commissions relating to Registrable Securities
included in any registration effected pursuant to Section 2.2 will be borne and
paid ratably by the Apollo Holders of such Apollo Registrable Securities and the
Company.  All fees and expenses of professionals retained by the Apollo Holders
in connection with any registration of Apollo Registrable Securities effected
pursuant to Section 2.2 will be borne and paid ratably by the Apollo Holders of
such Apollo Registrable Securities.

     2.7.  Underwriting Requirements.  In connection with any offering involving
           -------------------------                                            
an underwriting of securities to be sold for the account of the Company
(including for this purpose an underwriting of securities effected by the
Company for stockholders other than the Holders), the Company shall not be
required under Section 2.2 to include any of the Holders' securities in such
underwriting unless such Holders accept the terms of the underwriting as agreed
upon between the Company and the underwriters selected by it, and then only in
such quantity, if any, as will not, in the opinion of the underwriters,
jeopardize the success of the offering by the Company.  If the managing
underwriter for the offering shall advise the Company in writing that the total
number of securities, including Registrable Securities, requested by
stockholders to be included in such offering exceeds the number of securities
that

                                      -8-
<PAGE>
 
can be successfully offered, then the Company shall be required to include in
the offering only that number of securities, including Registrable Securities,
which the managing underwriter believes will not jeopardize the success of the
offering.  The securities so included in the offering will be reduced as
follows:

          (a)  first, all securities which any Persons other than the Company
     and any Demanding Stockholder seek to include in the offering shall be
     reduced pro rata among such Persons in accordance with the number of
     registrable securities of the Company; and

          (b)  if further limitation on the number of securities to be included
     in the offering is required, then the number of securities which the
     Company and any Demanding Stockholder seek to include in the offering shall
     be reduced.

     2.8.  Indemnification.  In the event any Apollo Registrable Securities are
           ---------------                                                     
included in a registration statement under this Section 2:

          (a)  The Company will indemnify and hold harmless each Apollo Holder,
     the officers and directors of each Apollo Holder, any underwriter (as
     defined in the 1933 Act) for such Apollo Holder and each Person, if any,
     who controls such Apollo Holder or underwriter within the meaning of the
     1933 Act or the 1934 Act (collectively, the "Apollo Holder Indemnitees"),
                                                  -------------------------   
     against any losses, claims, damages or liabilities (joint or several) to
     which they may become subject under the 1933 Act, the 1934 Act or any other
     federal or state law, insofar as such losses, claims, damages or
     liabilities (or actions in respect thereof) arise out of or are based upon
     any Violation.  The Company will reimburse each Apollo Holder Indemnitee
     for any legal or other expenses reasonably incurred by such Apollo Holder
     Indemnitee in connection with investigating or defending any such loss,
     claim, damage, liability or action.  The indemnity agreement contained in
     this Section 2.8(a) shall not apply to amounts paid in settlement of any
     loss, claim, damage, liability or action if such settlement is effected
     without the consent of the Company (which consent shall not be unreasonably
     withheld), nor shall the Company be liable to any Apollo Holder Indemnitee
     in any such case for any such loss, claim, damage, liability or action (i)
     to the extent that it arises out of or is based upon a Violation which
     occurs in reliance upon and in conformity with written information
     furnished expressly for use in connection with such registration by or on
     behalf of such Apollo Holder Indemnitee or (ii) in the case of a sale
     directly by an Apollo Holder of Apollo Registrable Securities (including a
     sale of such Apollo Registrable Securities through any underwriter retained
     by such Holder engaging in a distribution solely on behalf of such Apollo
     Holder), such untrue statement or alleged untrue statement or omission or
     alleged omission was contained in a preliminary prospectus and corrected in
     a final or amended prospectus, and such Apollo Holder failed to deliver a
     copy of the final or amended prospectus at or prior to the confirmation of
     the sale of the Apollo Registrable Securities to the Person asserting any

                                      -9-
<PAGE>
 
     such loss, claim, damage or liability in any case in which such delivery is
     required by the 1933 Act.

          (b)  Each Apollo Holder which includes any Apollo Registrable
     Securities in any registration statement (i) will indemnify and hold
     harmless the Company, its directors and officers, each Person, if any, who
     controls the Company within the meaning of the 1933 Act, each agent and any
     underwriter for the Company, and any other Apollo Holder or other
     stockholder selling securities in such registration statement and any of
     its directors and officers, and any Person who controls such Apollo Holder
     or such other stockholder or such underwriter (collectively, the "Company
                                                                       -------
     Indemnitees"), against any losses, claims, damages or liabilities (joint or
     -----------                                                                
     several) to which any Company Indemnitee may become subject under the 1933
     Act, the 1934 Act or other federal or state law, insofar as such losses,
     claims, damages or liabilities (or actions in respect thereto) arise out of
     or are based upon any Violation, in each case to the extent (and only to
     the extent) that such Violation occurs in reliance upon and in conformity
     with written information furnished by or on behalf of such Apollo Holder
     expressly for use in connection with such registration and (ii) will
     reimburse any legal or other expenses reasonably incurred by any Company
     Indemnitee in connection with investigating or defending any such loss,
     claim, damage, liability or action; provided, however, that the liability
                                         --------  -------                    
     of any Apollo Holder hereunder shall be limited to the amount of proceeds
     received by such Apollo Holder in the offering giving rise to the
     Violation; and provided, further, that the indemnity agreement contained in
                    --------  -------                                           
     this Section 2.8(b) shall not apply to amounts paid in settlement of any
     such loss, claim, damage, liability or action if such settlement is
     effected without the consent of such Holder (which consent shall not be
     unreasonably withheld) nor, in the case of a sale directly by the Company
     of its securities (including a sale of such securities through any
     underwriter retained by the Company to engage in a distribution solely on
     behalf of the Company), shall such Apollo Holder be liable to the Company
     in any case in which such untrue statement or alleged untrue statement or
     omission or alleged omission was contained in a preliminary prospectus and
     corrected in a final or amended prospectus, and the Company failed to
     deliver a copy of the final or amended prospectus at or prior to the
     confirmation of the sale of the securities to the Person asserting any such
     loss, claim, damage or liability in any case in which such delivery is
     required by the 1933 Act.

          (c)  Promptly after receipt by any Indemnitee under this Section 2.8
     of notice of the commencement of any action (including any governmental
     action), such Indemnitee will, if a claim in respect thereof is to be made
     against any indemnifying party under this Section 2.8, deliver to the
     indemnifying party a written notice of the commencement thereof and the
     indemnifying party shall have the right to participate in, and, to the
     extent the indemnifying party so desires, jointly with any other
     indemnifying party similarly noticed, to assume and control the defense
     thereof with counsel mutually satisfactory to the parties; provided,
                                                                -------- 
     however, that such Indemnitee
     -------                      

                                      -10-
<PAGE>
 
     shall have the right to retain its own counsel, with the fees and expenses
     to be paid by the indemnifying party, if representation of such Indemnitee
     by the counsel retained by the indemnifying party would be inappropriate
     due to actual or potential differing interests, as reasonably determined by
     either party, between such Indemnitee and any other party represented by
     such counsel in such proceeding.  The failure to deliver written notice to
     the indemnifying party within a reasonable time of the commencement of any
     such action, if prejudicial to its ability to defend such action, shall
     relieve such indemnifying party of any liability to the Indemnitee under
     this Section 2.8 to the extent of such prejudice, but the omission so to
     deliver written notice to the indemnifying party will not relieve it of any
     liability that it may have to such Indemnitee otherwise than under this
     Section 2.8.

          (d)  The obligations of the Company and the Apollo Holders under this
     Section 2.8 shall survive the completion of any offering of Apollo
     Registrable Securities in a registration statement whether under this
     Section 2 or otherwise.

          (e)  If the indemnification provided for in this Section 2.8 is
     unavailable to a party that would have been an Indemnitee under this
     Section 2.8 in respect of any losses, claims, damages or liabilities (or
     actions or proceedings in respect thereof) referred to herein, then each
     party that would have been an indemnifying party hereunder shall, in lieu
     of indemnifying such Indemnitee, contribute to the amount paid or payable
     by such indemnified party as a result of such losses, claims, damages or
     liabilities (or actions or proceedings in respect thereof) in such
     proportion as is appropriate to reflect the relative fault of such
     indemnifying party, on one hand, and such Indemnitee, on the other hand, in
     connection with the statements or omissions which resulted in such losses,
     claims, damages or liabilities (or actions or proceedings in respect
     thereof).  The relative fault shall be determined by reference to, among
     other things, whether the Violation relates to information supplied by such
     indemnifying party or such Indemnitee and the parties' relative intent,
     knowledge, access to information and opportunity to correct or prevent such
     Violation.  The parties agree that it would not be just and equitable if
     contribution pursuant to this Section 2.8(e) were determined by pro rata
     allocation or by any other method of allocation which does not take account
     of the equitable considerations referred to in the preceding sentence. The
     amount paid or payable by a contributing party as a result of the losses,
     claims, damages or liabilities (or actions or proceedings in respect
     thereof) referred to above in this Section 2.8(e) shall include any legal
     or other expenses reasonably incurred in connection with investigating or
     defending any such action or claim.  No Person guilty of fraudulent
     misrepresentation (within the meaning of Section 11(f) of the 1933 Act
     shall be entitled to contribution from any Person who was not guilty of
     such fraudulent misrepresentation.  The liability of any Apollo Holder of
     Apollo Registrable Securities in respect of any contribution obligation of
     such Holder (after deduction of all underwriters' discounts and commissions
     paid by such Apollo Holder in connection with the registration in question)
     arising under this Section 2.8(e) shall not in any event

                                      -11-
<PAGE>
 
     exceed an amount equal to the proceeds to such Apollo Holder from the
     disposition of the Apollo Registrable Securities disposed of by such Apollo
     Holder pursuant to such registration.

     2.9.  Reports Under Securities Exchange Act of 1934.  With a view to making
           ---------------------------------------------                        
available to the Apollo Holders the benefits of Rule 144 and any other rule or
regulation of the SEC that may at any time permit an Apollo Holder to sell
securities of the Company to the public without registration, and with a view to
making it possible for Apollo Holders to register the Apollo Registrable
Securities pursuant to a registration on Form S-3, the Company agrees to:

          (a)  to the extent required by the 1934 Act, use its best efforts to
     make and keep public information available, as those terms are understood
     and defined in Rule 144, at all times;

          (b)  use its best efforts to file with the SEC in a timely manner all
     reports and other documents required of the Company under the 1933 Act and
     the 1934 Act; and

          (c)  furnish to any Apollo Holder, so long as such Apollo Holder owns
     any Apollo Registrable Securities, forthwith upon request (i) a written
     statement by the Company as to its compliance with the reporting
     requirements of Rule 144, the 1933 Act and the 1934 Act, or as to its
     qualification as a registrant whose securities may be resold pursuant to
     Form S-3, (ii) a copy of the most recent annual or quarterly report of the
     Company and such other reports and documents so filed by the Company and
     (iii) such other information as may be reasonably requested in availing any
     Apollo Holder of any rule or regulation of the SEC which permits the
     selling of any such securities without registration or pursuant to such
     form.

     2.10.  Form S-3 Registration.  In case the Company shall receive from any
            ---------------------                                             
Apollo Holder a written request that the Company effect a registration on Form
S-3 and any related qualification or compliance with respect to all or a part of
the Apollo Registrable Securities owned by such Holder, the Company will:

          (a)   promptly give written notice of the proposed registration, and
     any related qualification or compliance, to all other Holders; and

          (b)  use its best efforts to effect, as soon as practicable, such
     registration, qualification or compliance as may be so requested and as
     would permit or facilitate the sale and distribution of all or such portion
     of such Apollo Holder's Apollo Registrable Securities as are specified in
     such request, together with all or such portion of the Registrable
     Securities of any other Holder joining in such request as are specified in
     a written request given within 20 days after receipt of such written notice
     from the

                                      -12-
<PAGE>
 
     Company; provided, however, that the Company shall not be obligated to
              --------  -------                                            
     effect any such registration, qualification or compliance, pursuant to this
     Section 2.10 if:

               (i)  Form S-3 is not available for such offering by the Holders;

               (ii)  the aggregate net offering price (after deduction of
          underwriting discounts and commissions) of the Apollo Registrable
          Securities specified in such request is not at least $3,000,000;

               (iii)  the Company has already effected a registration within the
          previous six-month period; or

               (iv)  the Company shall furnish to the Holders a certificate
          signed by the president of the Company (A) stating that, in the good
          faith judgment of a majority of the disinterested members of the Board
          of Directors, (1) an undisclosed material event (x) has occurred and
          is continuing or (y) is likely to occur within 90 days and (2) the
          disclosure of such undisclosed material event would have a material
          adverse effect on the Company or on a proposed material transaction
          involving the Company or a substantial portion of its assets and (B)
          describing in reasonable detail such undisclosed material event, in
          which event the Company shall have the right to defer the filing of
          such Form S-3 registration for a period of not more than 120 days
          after receipt of the request of the Apollo Holder or Apollo Holders

competent jurisdiction to be invalid or unenforceable, the parties hereby waive
