Item 1.   SECURITY AND ISSUER

     This statement relates to the common stock, $.001 par value per share
("Common Stock"), of Citadel Communications Corporation, a Nevada corporation
(the "Company").  The Company's principal executive offices are located at 140
South Ash Avenue, Tempe, Arizona 85821.

Item 2.   IDENTITY AND BACKGROUND

     This Schedule 13D is filed by Baker, Fentress & Company, a Delaware
corporation ("BKF").  BKF's principal business is that of an investment company
registered under Section 8 of the Investment Company Act of 1940.  Its principal
executive offices are located at 200 West Madison Street, Suite 3510, Chicago,
Illinois 60606.  The name, business address and present principal occupation of
each of the directors and executive officers of BKF are set forth in Annex I,
which is attached hereto and incorporated herein by reference.
 
     During the last five years, neither BKF nor any of the persons listed on
Annex I has been convicted in any criminal proceeding (excluding traffic
violations or similar misdemeanors).

     During the last five years, neither BKF nor any of the person listed on
Annex I has been a party to any civil proceeding of a judicial or administrative
body of competent jurisdiction and as a result of such proceeding was or is
subject to a judgment, decree or final order enjoining future violations of, or
prohibiting or mandating activities subject to, federal or state securities laws
or any violation with respect to such laws.

     All of the citizens identified on Annex I are citizens of the United States
of America.

ITEM 3.   SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

     On June 28, 1996, in exchange for another series of preferred stock of the
Company then outstanding, BKF received 746,412 shares of Old Preferred Stock (as
hereinafter defined) for an aggregate purchase price of $1,860,996.

     Immediately prior to the recently completed initial public offering (the
"Offering") by the Company (as discussed below), the Company undertook a
recapitalization (the "Recapitalization").  Prior to the Recapitalization, the
Company's capital stock consisted of three classes of common stock ("Old Common
Stock") and seven classes of preferred stock (including those shares of Series A
Convertible Preferred Stock held by BKF) (the "Old Preferred Stock").  In
connection with the Recapitalization, each outstanding share of Old Common Stock
and each outstanding share of Old Preferred Stock, other than those shares of
Old Preferred Stock owned beneficially or of record by ABRY Broadcast 
<PAGE>
 
Partners II, L.P. ("ABRY II") and ABRY/Citadel Investment Partners, L.P.
("ABRY/CIP"), converted into three shares of Common Stock. The outstanding
shares of Old Preferred Stock owned beneficially or of record by ABRY II and
ABRY/CIP converted into three shares of convertible preferred stock, par value
$.001 per share (the "Convertible Preferred Stock"). As a result of the
Recapitalization, BKF held 2,239,236 of Common Stock.

     After giving effect to the Recapitalization, holders of the Common Stock,
including BKF, and holders of the Convertible Preferred Stock were and are
entitled to one vote per share on all matters submitted to a vote of
stockholders generally.  Both classes vote together as a single class on all
matters except the election or removal of the Class B Director, for which only
the holders of Convertible Preferred Stock are entitled to vote.

ITEM 4.    PURPOSE OF TRANSACTION

     Except as set forth in this Item 4, the Company has no present plans or
proposals that relate to or that could result in any of the actions specified in
clauses (a) through (j) of Item 4 of Schedule 13D.  The responses to Items 3 and
6 of this Schedule 13D are hereby incorporated by reference into the response to
Item 4.

     BKF initially acquired the shares of Old Preferred Stock for investment
purposes, and acquired the Common Stock pursuant to the Recapitalization.
Depending upon market and other considerations, BKF may acquire additional
Common Stock if such securities become available at prices that are attractive.
However, depending on market and other conditions, BKF may dispose of all or a
portion of the Common Stock that it now, or hereinafter owns, subject to a
"lockup" period of 180 days that will expire on December 27, 1998.

     Scott E. Smith, Executive Vice President of BKF, is a member of the Board
of Directors of the Company. Mr. Smith has been a member of the Board of
Directors of the Company since 1993 (and of the predecessor of the Company since
1992) and, prior to the Offering, served in such capacity pursuant to the Fourth
Amended and Restated Voting Agreement dated as of October 15, 1997 (the "Voting
Agreement"), by and among the Company and certain other stockholders of the
Company, including BKF. In connection with the Offering, the Voting Agreement
was terminated and Mr. Smith became a Class A Director of the Company to serve
in such capacity until reelected at the next annual meeting of the stockholders
of the Company. Mr. Smith currently also serves as a member of the Compensation
Committee of the Board of Directors.

ITEM 5.   INTEREST IN SECURITIES OF THE ISSUER

     BKF has been informed by the Company that immediately following the
Offering, there were 15,180,664 shares of Common Stock issued and outstanding
shares. BKF owns approximately 14.75% of the outstanding shares of Common Stock.
That amount
<PAGE>
 
of shares issued and outstanding does not include (i) shares that may be issued
by certain underwriters in a over-allotment option in connection with the
Offering, (ii) certain other shares of Common Stock issuable upon exercise of
options, or (iii) shares of Common Stock reserved under the Company's 1996
Equity Incentive Plan. The amount of shares of Common Stock outstanding also
does not give effect to the conversion of shares of Convertible Preferred Stock
which are convertible on a one-for-one basis into shares of Common Stock at the
option of the holders thereof. Pursuant to Rule 13d-3(d)(1)(i) of the Securities
Exchange Act of 1934, shares of Common Stock which are not outstanding but which
are subject to among other things the exercise or an option, warrant or right or
through the conversion of a security, are deemed to be outstanding for the
purpose of computing the percentage of outstanding securities of the shares of
Common Stock owned by the person holding such rights, but are not deemed to be
outstanding for purposes of computing the percentage of such shares owned by any
other person.

     Had the Convertible Preferred Stock converted into shares of Common Stock
as of the date hereof, 24,687,225 share of Common Stock would be issued and
outstanding and BKF would be deemed to the beneficial owner of 9.1% of the
issued and outstanding shares of Common Stock.

     On June 28, 1996, BKF, along with certain other stockholders of Company, 
entered into the Third Amended and Restated Registration Rights Agreement with
the Company pursuant to which the Company, under circumstances, is required to
register their shares of Common Stock under the Securities Act of 1933 for offer
and sale to the public.

     Except in connection with the transaction described herein, neither BKF
nor, to the best of its knowledge, any person listed in Annex I hereto, has
effected any transactions in the securities of the Company during the preceding
60 days.

ITEM 6.   CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT
          TO SECURITIES OF THE ISSUER

     The responses to Item 4 of this Schedule 13D hereby incorporated by
reference into the response to Item 6.

ITEM 7.   MATERIAL TO BE FILED AS EXHIBITS

     1.   Fourth Amended and Restated Voting Agreement dated as of October 15,
          1997

     2.   Third Amended and Restated Registration Rights Agreement dated 
          June 28, 1996 and amendments thereto.

          AGREEMENT DATED AS OF OCTOBER 15, 1997, AS AMENDED AMONG THE ISSUER OF
          SUCH SECURITIES (THE "COMPANY") AND CERTAIN OF THE COMPANY'S
          STOCKHOLDERS, AND THE COMPANY RESERVES THE RIGHT TO REFUSE THE
          TRANSFER OF SUCH SECURITIES UNTIL SUCH TERMS AND CONDITIONS HAVE BEEN
          FULFILLED WITH RESPECT TO SUCH TRANSFER. A COPY OF SUCH VOTING
          AGREEMENT WILL BE FURNISHED BY THE COMPANY TO THE HOLDER HEREOF
          WITHOUT CHARGE UPON WRITTEN REQUEST.

The legend forth set forth above shall be removed from the certificates
evidencing shares which cease to be Stockholder Shares upon (a) the date on
which such Stockholder Share has been transferred in a Public Sale, (b) the
fifteenth anniversary of the date of this Agreement (unless extended in
accordance with the General Corporation Law of Nevada), or (c) the consummation
of a Qualified Public Offering.

          5.   TRANSFERS. Prior to Transferring any Stockholder Shares (other
than in a Public Sale), to any Person, the transferring Stockholder shall cause
the prospective transferee to execute and deliver to the Company and the other
Stockholders a counterpart of this Agreement. Any Transfer or attempted Transfer
of any Stockholder Shares in violation of any provision of this Agreement will
be void, and the Company will not record such Transfer on its books or treat any
purported transferee of such Stockholder Shares as the owner of such shares for
any purpose.

          6.   MISCELLANEOUS.

               6.1  REMEDIES. Each holder of Stockholder Shares will have all
rights and remedies set forth in this Agreement, the Certificate of
Incorporation and all rights and remedies which such holders have been granted
at any time under any other agreement or contract and all of the rights which
such holders have under any law. Any Person having any rights under any
provision of this Agreement will be entitled to enforce such rights
specifically, without posting a bond or other security, to recover damages by
reason of any breach of any provision of this Agreement and to exercise all
other rights granted by law. The parties hereto agree and acknowledge that money
damages may not be an adequate remedy for any breach of the provisions of this
Agreement and that any Stockholder may in his, her or its sole discretion apply
to any court of law or equity of competent jurisdiction for specific performance
and/or injunctive relief in order to enforce or prevent any violation of the
provisions of this Agreement.

               6.2  CONSENT TO AMENDMENTS. Except as otherwise provided herein,
no modification, amendment or waiver of any provision of this Agreement will be
effective against the Company or any holder of Stockholder Shares unless such
modification, amendment or waiver is approved in writing by the Company, the
beneficial owners (meaning ABRY and ABRY/CIP, in the case of Voting Trust Stock
which is held in the Voting Trust) of a majority of the Voting Trust Underlying
Common Stock, the holders of a majority of the BFC Underlying Common Stock, the
holders of a majority of the Endeavour Underlying Common Stock, the holders of a
majority of the Urso Underlying Common Stock, the holders of a majority of the
Snider Underlying Common Stock, and LRW, respectively. The failure of any party
to enforce any of the provisions of this Agreement will in no way be construed
as a waiver of such provisions and will not affect the right of such party
thereafter to enforce each and every provision of this Agreement in accordance
with its terms.

               6.3  SUCCESSORS AND ASSIGNS. Except as otherwise expressly
provided herein, all covenants and agreements contained in this Agreement by or
on behalf of any of the parties hereto will bind and inure to the benefit of the
respective successors and assigns of the parties hereto whether so expressed or
not. In addition, and whether or not any express assignment has been made, the
provisions of this Agreement which are for any Stockholder's benefit as a
purchaser or holder of Stockholder Shares are also for the benefit of,
enforceable by, and binding upon, any subsequent holder of such Stockholder
Shares.
               6.4  ENTIRE AGREEMENT. Except as otherwise expressly set forth
herein, this document embodies the complete agreement and understanding among
the parties hereto with respect to the subject matter hereof and supersedes and
preempts any prior understandings, agreements or representations by or among the
parties, written or oral, including the Voting Agreement dated October 1, 1993,
the Amended and Restated Voting Agreement dated as of June 28, 1996, the Second
Amended and Restated Voting Agreement dated as of December 31,

1996, and the Voting Agreement (as defined herein), which may have related to
the subject matter hereof in any way.

               6.5  SEVERABILITY. Whenever possible, each provision of this
Agreement will be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be prohibited
by or invalid under applicable law, such provision will be ineffective only to
the extent of such prohibition or invalidity, without invalidating the remainder
of this Agreement.

               6.6  COUNTERPARTS. This Agreement may be executed in two or more
counterparts, any one of which need not contain the signatures of more than one
party, but all such counterparts taken together will constitute one and the same
Agreement.

               6.7  DESCRIPTIVE HEADINGS. The descriptive headings of this
Agreement are inserted for convenience only and do not constitute a part of this

               6.10  CONSTRUCTION. The language used in this Agreement will be
deemed to be the language chosen by the parties to express their mutual intent,
and no rule of strict construction will be applied against any party. Any
reference to any federal, state, local, or foreign statute or law will be deemed
also to refer to all rules and regulations promulgated thereunder, unless the
context requires otherwise. The use of the word "including" in this Agreement is
intended by the parties to be by way of example rather than limitation.

               6.11  GOVERNING LAW. THE GENERAL CORPORATION LAW OF THE STATE OF
NEVADA WILL GOVERN ALL ISSUES CONCERNING THE RELATIVE RIGHTS OF THE COMPANY AND
ITS STOCKHOLDERS. ALL OTHER QUESTIONS CONCERNING THE CONSTRUCTION, VALIDITY AND

<PAGE>
 
THIS AGREEMENT WILL BE GOVERNED BY THE INTERNAL LAW, AND NOT THE LAW OF
CONFLICTS, OF THE STATE OF NEVADA.

               6.12  SUBMISSION TO JURISDICTION. Each of the parties to this
Agreement submits to the jurisdiction of any state or federal court sitting in
Boston, Massachusetts, Chicago, Illinois, Nevada or Arizona in any action or
proceeding arising out of or relating to this Agreement, agrees that all claims
in respect of the action or proceeding may be heard and determined in any such
court, and agrees not to bring any action or proceeding arising out of or
relating to this Agreement in any other court. Each of the parties to this
Agreement waives any defense of inconvenient forum to be maintenance of any
action or proceeding so brought and waives any bond, surety, or other security
that might be required of any other party with respect thereto. Each party to
this Agreement appoints CT Corporation System (the "Process Agent"), with
addresses of 208 South LaSalle Street, Chicago, Illinois 60604, One East First
Street, Reno, Nevada, Suite 1601, 3225 North Central Avenue, Phoenix, Arizona
85012, and 2 Oliver Street, Boston, Massachusetts 02109, as its agent to receive

Agreement may make service on any other party by sending or delivering a copy of
the process (a) to the party to be served at the address and in the manner
provided for the giving of notices in Section 6.8 or (b) to the party to be
served in care of the Process Agent at the address and in the manner provided
for the giving of notices in Section 6.8. Nothing in this Section 6.12, however,
will affect the right of any party to serve legal process in any other manner
permitted by law. Each party agrees that a final judgment in any action or
proceeding so brought will be conclusive and may be enforced by suit on the
judgment or in any other manner provided by law.

               6.13  FCC MATTERS. Notwithstanding any provision contained herein
to the contrary, no party hereto may exercise any of its rights or remedies
hereunder, or take any actions permitted hereby, if prior thereto the Company
receives a written opinion from its nationally recognized FCC counsel that after
consultation with the staff of the Federal Communications Commission ("FCC")
such exercise or action will violate the Communication Act of 1934 or the rules,
regulations, or policies promulgated thereunder.

               6.14  INCORPORATION OF RECITALS. The Recitals set forth in this

initial public offering of the Company's Common Stock which is registered
pursuant to the Securities Act (other than on Form S-8) or (ii) August 1, 2000,
the Holders of a majority of the shares of Conversion Stock constituting

Registration Statement under the Securities Act covering the shares of
Restricted Stock that are the subject of such request. Any such request will be
accompanied by a statement of the range of proposed offering prices for the
offering of such Restricted Stock.

                                      -7-
<PAGE>
 
          (b)  Number of Demand Registrations

          The Company shall be obligated to prepare, file and cause to become
effective, pursuant to this Section 2, one Registration Statement in connection
with which the Company will bear all Registration Expenses. If (i) the Company
withdraws a Registration Statement filed pursuant to a Demand Registration prior
to the effectiveness thereof, (ii) the sale of securities to which a
Registration Statement filed pursuant to a Demand Registration applies is not
consummated because of the failure of the Company to comply with the provisions
of Section 5 hereof, or (iii) upon the consummation of a sale of securities to
which a Registration Statement filed pursuant to a Demand Registration applies,
less than 80% of the securities requested to be registered for sale thereunder
is sold, such Registration Statement shall not be counted as the one Demand
Registration in connection with which the Company will bear all Registration
Expenses or otherwise adversely affect such Holder's rights hereunder.

          (c)  Required Thresholds

          The Company shall not be obligated to prepare, file and cause to
become effective pursuant to this Section 2 a Registration Statement unless the
proposed aggregate number of shares of Conversion Stock to be included in such
Demand Registration equals the greater of (i) at least 25% of the outstanding
shares of Conversion Stock and (ii) such number of shares, the sale of which
would result in aggregate net proceeds in excess of $3,000,000, based on the 
mid-point of the range of offering prices proposed by the Holders making the
request pursuant to Section 2(a).

          (d)  Participation

          The Company shall promptly give written notice to all Holders of
Restricted Stock upon receipt of a request for a Demand Registration pursuant to
Section 2(a) above. The Company shall include in such Demand Registration such
shares of Restricted Stock for which it has received written requests to
register such shares within 30 days after such written notice has been given.

          (e)  Underwriter's Cutback

          If the public offering of Restricted Stock is to be underwritten and,
in the good faith judgment of the managing underwriter, the inclusion of all the
Restricted Stock requested to be registered hereunder would interfere with the
successful marketing of a smaller number of such shares of Restricted Stock, the
number of shares of Restricted Stock to be included shall be reduced to such
smaller number with the participation in such offering to be pro rata among the
Holders of Restricted Stock requesting such registration, based upon the number
of shares of Restricted Stock owned by such Holders.

                                      -8-
<PAGE>
 
          Any shares that are thereby excluded from the offering shall be
withheld from the market by the Holders thereof for a period (not to begin more
than 30 days prior to the proposed effective date nor continue for more than 90
days thereafter) that the managing underwriter reasonably determines is
necessary in order to effect the underwritten pubic offering.

          The Company and, subject to the requirements of Section 11 hereof,
other Holders of applicable securities of the Company may include such
securities in such Registration if, but only if, the managing underwriter
concludes that such inclusion will not interfere with the successful marketing
of all the Restricted Stock requested to be included in such registration.

          (f)  Managing Underwriter

          The managing underwriter or underwriters of any underwritten public
offering covered by a Demand Registration shall be selected by the Holders of a
majority of the shares of Restricted Stock that initiate such registration,
subject to the approval of the Board of Directors, which shall not be
unreasonably withheld.

     3.   Piggyback Registrations

          (a)  Participation

          Each time the Company decides to file a registration statement under
the Securities Act (other than on Forms S-4 or S-8 or pursuant to Section 2
hereof) covering the offer and sale by the Company or any of its respective
security holders of any of its securities for money, the Company shall give
written notice thereof to all Holders of Restricted Stock. The Company shall
include in such registration statement such shares of Restricted Stock for which
it has received written requests to register such shares within 30 days after
such written notice has been given. If the registration statement is to cover an
underwritten offering, such Restricted Stock shall be included in the
underwriting on the same terms and conditions as the securities otherwise being
sold through the underwriters.

                                      -9-
<PAGE>
 
          (b)  Underwriter's Cutback

          Subject to the requirements of Section 11 hereof, if in the good faith
judgment of the managing underwriter of such offering the inclusion of all of
the shares of Restricted Stock and any other securities requested to be
registered would interfere with the successful marketing of a smaller number of
such shares, then the number of shares of Restricted Stock and other securities
to be included in the offering (except for securities to be issued by the
Company in an offering initiated by the Company) shall be reduced to such
smaller number with the participation in such offering to be in the following
order of priority: (1) first Restricted Stock requested to be included, and (2)
second, any other securities requested to be included. Any necessary allocation
among the Holders of shares within each of the foregoing groups shall be pro
rata among such Holders requesting such registration based upon the number of
shares of Restricted Stock or other securities, as applicable, owned by such
Holders. All shares so excluded from the underwritten public offering shall be
withheld from the market by the Holders thereof for a period (not to begin more
than 30 days prior to the proposed effective date nor continue for more than 90
days thereafter) that the managing underwriter reasonably determines is
necessary in order to effect the underwritten public offering.

          (c)  Registrant Controls

          The Company may decline to file a Registration Statement described in
Section 3(a) above after giving notice to any Holder or withdraw any such
Registration Statement after filing and after such notice, but prior to the
effectiveness thereof, provided that such registrant shall promptly notify each
Holder in writing of any such action and provided further that such registrant
shall bear all reasonable expenses incurred by such Holder or otherwise in
connection with such withdrawn Registration Statement.

                                      -10-

     4.   Hold-Back Agreements
          --------------------

          (a)  By Holders of Restricted Stock; Wilson
               --------------------------------------

          Upon the written request of the managing underwriter of any
underwritten offering of the Company's securities, neither Wilson nor a Holder
of Restricted Stock shall sell, make any short sale of, loan, grant any option
for the purchase of, or otherwise dispose of any Restricted Stock (other than
those included in such registration) without the prior written consent of such
managing underwriter for a period (not to begin more than 30 days before the
proposed effective date nor continue for more than 90 days thereafter) that such
managing underwriter reasonably determines is necessary in order to effect the
underwritten public offering. In addition, the Company will use its best efforts
to cause each of the officers and directors of the registrant to enter into
substantially similar holdback agreements with such managing underwriter
covering at least the same period. Lawrence R. Wilson does hereby agree, by his
execution hereof, to enter into substantially similar holdback agreements with
such managing underwriter covering at least the same period.

          (b)  By the Company and Others
               -------------------------

          The Company agrees:

               (1)  not to effect any public or private sale or distribution of
its Equity Securities during the 30-day period prior to, and during the 90-day
period after, the effective date of each underwritten offering made pursuant to
a Demand Registration or a Piggyback Registration, if so requested in writing by
the managing underwriter (except as part of such underwritten offering or
pursuant to registrations on Form S-4 or S-8), and

               (2)  not to issue any Equity Securities other than for sale in a
registered public offering unless each of the Persons to which such securities
are issued has entered a written agreement binding on its transferees not to
effect any public sale or distribution of such securities during such period,
including without limitation a sale pursuant to Rule 144 under the Securities
Act (except as part of such underwritten registration, if and to the extent
permitted hereunder).

     5.   Registration Procedures
          -----------------------

          If and whenever the Company is required to register Restricted Stock
in a Demand Registration or a Piggyback Registration, the Company will use its
best efforts to effect such registration to permit the sale of such Restricted
Stock in accordance with the intended plan of distribution thereof, and pursuant
thereto the Company will as expeditiously as possible:

effectiveness of any Registration Statement not covering an underwritten public
offering for more than 90 days after such registration statement becomes
effective; and further provided that before filing a Registration Statement or
Prospectus or any amendments or supplements thereto, the registrant shall
furnish to the Holders of the Restricted Stock covered by such Registration
Statement and the underwriters, if any, draft copies of all such documents
proposed to be filed, which documents will be subject to the review of such
Holders and underwriters, and the registrant shall not file any Registration
Statement of amendment thereto or any Prospectus or any supplement thereto to
which the Holders of a majority of the Restricted Stock covered by such
Registration Statement or the underwriters, if any, shall reasonably object;

          (b) prepare and file with the Commission such amendments and post-
effective amendments to the Registration Statement, and such supplements to the
Prospectus, as may be requested by any Holder of Restricted Stock or any
underwriter of Restricted Stock or as may be required by the rules, regulations
or instructions applicable to the registration form used by the registrant or by
the Securities Act or rules and regulations thereunder to keep the Registration
Statement effective until all shares of Restricted Stock covered by such
Registration Statement are sold in accordance with the intended plan of
distribution set forth in such Registration Statement or supplement to the
Prospectus or for such shorter period of time during which such Registration
Statement must be kept effective by the terms of this Agreement;

          (c) promptly notify the applicable selling Holders of Restricted Stock

has been filed, and, with respect to the Registration Statement or any post-

the Registration Statement, the Prospectus or for additional information,

          (3) of the issuance by the Commission of any order suspending the
effectiveness of the Registration Statement or the initiation of any proceedings
for that purpose,

          (4) if at any time the representations and warranties of the Company
contemplated by clause (1) of paragraph (o) below cease to be accurate in all
material respects,

to the suspension of the qualification of the Restricted Stock for sale in any
jurisdiction or the initiation or threatening of any proceeding for such
purpose, and


                                      -13-
<PAGE>
 
          (6) of the existence of any fact which results in the Registration
Statement, the Prospectus or any document incorporated therein by reference
containing a Misstatement;

               (5) deliver such documents and certificates as may be requested
by the Holders of a majority of the Restricted Stock being sold and the managing

     7.    Indemnification
          ----------------

          (a)    Indemnification by the Company
                -------------------------------

          The Company (the "Indemnifying Party") agrees to indemnify and hold
harmless each Indemnified Holder from and against all Claims arising out of or
based upon any Misstatement or alleged Misstatement, except insofar as such
Misstatement or alleged Misstatement was based upon information furnished in
writing to the registrant by such Indemnified Holder expressly for use in the
document containing such Misstatement or alleged Misstatement.  This indemnity
shall not be exclusive and shall be in addition to any liability which the
Company may otherwise have.

          The foregoing notwithstanding, the Indemnifying Party shall not be
liable to the extent that any such Claim arises out of or is based upon a
Misstatement or alleged Misstatement made in any preliminary prospectus if (i)
such Indemnified Holder failed to send or deliver a copy of the Prospectus with
or prior to the delivery of written confirmation of the sale of
                
                                     -18-
<PAGE>
 
Restricted Stock giving rise to such Claim and (ii) the Prospectus would have
corrected such untrue statement or omission.

          In addition, the Indemnifying Party shall not be liable to the extent
that any such Claim arises out of or is based upon a Misstatement or alleged
Misstatement in a Prospectus, (x) if such Misstatement or alleged Misstatement
is corrected in an amendment or supplement to such Prospectus and (y) having
previously been furnished by or on behalf of the Indemnifying Party with copies
of the Prospectus as so amended or supplemented, such Indemnified Holder
thereafter fails to deliver such Prospectus as so amended or supplemented prior
to or concurrently with the sale to the person who purchased the Restricted
Stock from such Indemnified Holder and who is asserting such Claim.

          The Indemnifying Party shall also indemnify underwriters, selling
brokers, dealer managers and similar securities industry professionals
participating in a distribution covered by a Registration Statement, their
officers and directors and each Person who controls such Persons (within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act)
to the same extent as provided above with respect to the indemnification of the
Indemnified Holders of Restricted Stock.

          (b)  Indemnification Procedures
               --------------------------

          If any action or proceeding (including any governmental investigation
or inquiry) shall be brought or asserted against an Indemnified Holder in
respect of which indemnity may be sought from the Indemnifying Party, such
Indemnified Holder shall promptly notify the Indemnifying Party in writing, and
the Indemnifying Party shall assume the defense thereof, including the
employment of counsel satisfactory to such Indemnified Holder and the payment of
all expenses.

          Such Indemnified Holder shall have the right to employ separate
counsel in any such action and to participate in the defense thereof, but the
fees and expenses of such separate counsel shall be the expense of such
Indemnified Holder unless (i) the Indemnifying Party has agreed to pay such fees
and expenses, (ii) the Indemnifying Party shall have failed to assume the
defense of such action or proceeding or has failed to employ counsel
satisfactory to such Indemnified Holder in any such action or proceeding or
(iii) the named parties to any such action or proceeding (including any
impleaded parties) include both such Indemnified Holder and the Indemnifying
Party, and such Indemnified Holder shall have been advised by counsel that there
may be one or more legal defenses available to such Indemnified Holder that are
different from or additional to those available to the Indemnifying Party.

          If such Indemnified Holder notifies the Indemnifying Party in writing
that it elects to employ separate counsel at the expense of the Indemnifying
Party as permitted by the provisions of the preceding paragraph, the
Indemnifying Party shall not have the right to assume 
        
                                     -19-
<PAGE>
 
the defense of such action or proceeding on behalf of such Indemnified Holder.
The foregoing notwithstanding, the Indemnifying Party shall not be liable for
the reasonable fees and expenses of more than one separate firm of attorneys at
any time for such Indemnified Holder and any other Indemnified Holders (which
firm shall be designated in writing by such Indemnified Holders) in connection
with any one such action or proceeding or separate but substantially similar or
related actions or proceedings in the same jurisdiction arising out of the same
general allegations or circumstances.

          The Indemnifying Party shall not be liable for any settlement of any
such action or proceeding effected without its written consent, but if settled
with its written consent, or if there be a final judgment for the plaintiff in
any such action or proceeding, the Indemnifying Party agrees to indemnify and
hold harmless such Indemnified Holders from and against any loss or liability by
reason of such settlement or judgment.

          (c)  Indemnification by Holder of Restricted Stock
               ---------------------------------------------

          Each Holder of Restricted Stock agrees to indemnify and hold harmless
the Company, their respective directors and officers and each Person, if any,
who controls the Company within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act to the same extent as the
foregoing indemnity from the Indemnified Party to such Holder, but only with
respect to information relating to such Holder furnished in writing by such
Holder expressly for use in any Registration Statement, Prospectus or
preliminary prospectus.  In no event, however, shall the liability hereunder of
any selling Holder of Restricted Stock be greater than the dollar amount of the
proceeds received (net of underwriting commissions and discounts) by such Holder
upon the sale of the Restricted Stock giving rise to such indemnification
obligation.

          In case any action or proceeding shall be brought against the Company
or its directors or officers or any such controlling person, in respect of which
indemnity may be sought against a Holder of Restricted Stock, such Holder shall
have the rights and duties given the Company or its directors of officers and
such controlling person shall have the rights and duties given to each Holder by
Section 7(a) and 7(b) above.

          The Company shall be entitled to received indemnities from
underwriters, selling brokers, dealer managers and similar securities industry
professionals participating in the distribution, to the same extent as provided
above with respect to information so furnished in writing by such Persons
specifically for inclusion in any Prospectus or Registration Statement.

                                     -20-
<PAGE>
 
          (d)  Contribution
               ------------

          If the indemnification provided for in this Section 7 is unavailable
to an indemnified party under Section 7(a) or Section 7(c) above (other than by
reason of exceptions provided in those Sections) in respect of any Claims
referred to in such Sections, then each applicable 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 Claims in such proportion
as is appropriate to reflect the relative fault of the Company on the one hand
and of the Indemnified Holder on the other in connection with the statements or
omissions which resulted in such Claims as well as any other relevant equitable
considerations. The amount paid or payable by a party as a result of the Claims
referred to above shall be deemed to include, subject to the limitations set
forth in Section 7(b), any legal or other fees or expenses reasonably incurred
by such party in connection investigating or defending any action or claim.

          The relative fault of the Company on the one hand and of the
Indemnified Holder on the other shall be determined by reference to, among other
things, whether the Misstatement or alleged Misstatement related to information
supplied by the Company or by the Indemnified Holder and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such Misstatement or alleged Misstatement.

          The Company and each Holder of Restricted Stock agree that it would
not be just and equitable if contribution pursuant to this Section 7(d) were
determined by pro rata allocation or by any other method of allocation which
does not take account of the equitable considerations referred to above.

          Notwithstanding the provisions of this Section 7(d), an Indemnified
Holder shall not be required to contribute any amount in excess of the amount by
which (i) the total price (net of underwriting commissions and discounts) at
which the securities that were sold by such Indemnified Holder and distributed
to the public were offered to the public exceeds (ii) the amount of any damages
which such Indemnified Holder has otherwise been required to pay by reason of
such Misstatement.

          No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation.

     8.   Exchange Act Reporting Requirements
          -----------------------------------

          When it is first legally required to do so, the Company shall register
its Common Stock under Section 12 of the Exchange Act and shall timely file such
information, documents and reports as the Commission may require or prescribe
under Section 13 of the Exchange Act.  From and after the effective date of the
first registration statement filed by the Company under the Securities Act, the
Company shall (whether or not it shall then be required to do so) timely file
such information, documents and reports as the Commission may require or
prescribe under Section 13 or 15(d) (whichever is applicable) of the Exchange
Act.  In addition, the Company shall take such other measures and file such
other information, documents and reports, as shall hereafter be required by the
Commission as a condition to the availability of Rule 144 under the Securities
Act (or any successor provision) and the use of Form S-3.

          Immediately upon becoming subject to the reporting requirements of
either Section 13 or 15(d) of the Exchange Act, the Company shall forthwith upon
request furnish any Holder of applicable Restricted Stock (i) a written
statement by the Company that it has complied with such reporting requirements,
(ii) a copy of the most recent annual or quarterly report of the Company and
(iii) such other reports and documents filed by the Company with the Commission
as such Holder may reasonably request in availing itself of an exemption for the
sale of Restricted Stock without registration under the Securities Act.

          The purpose of the foregoing requirements are (x) to enable any such
Holder to comply with the current public information requirements contained in
paragraph (c) of Rule 144 under the Securities Act (or any successor provision)
and (y) to qualify the Company for the use of registration statements on Form S-
3.

     9.   Requirements for Participation in Underwritten Offerings
          --------------------------------------------------------

          No Person may participate in any underwritten offering pursuant to a
Registration hereunder unless such Person (a) agrees to sell such Person's
securities on the basis provided in any underwriting arrangements approved by
the Persons entitled hereunder to approve such arrangements and (b) completes
and executes all questionnaires, powers of attorney, indemnities, underwriting
agreements and other documents required under the terms of such underwriting
arrangements.

<PAGE>
 
     10.  Suspension of Sales
          -------------------

          Upon receipt of written notice from the Company that a Registration
Statement or Prospectus contains a Misstatement, each Holder of Restricted Stock
shall forthwith discontinue disposition of Restricted Stock until such Holder
has received copies of the supplemented or amended Prospectus required by
Section 5(1) hereof, or until such Holder is advised in writing by the
registrant that the use of the Prospectus may be resumed, and, if so directed by
the registrant, such Holder shall deliver to the registrant (at the registrant's
expense) all copies, other than permanent file copies then in such Holder's
possession, of the Prospectus covering such Restricted Stock current at the time
of receipt of such notice.  In the event the registrant shall give any such
notice, the 90-day period referred to in Section 5(a) hereof shall be extended
by the number of days during the period from and including the date of the
giving of such notice to and including the date when each seller of Restricted
Stock covered by such Registration Statement either has received  the copies of
the supplemented or amended prospectus contemplated by Section 5(1) hereof or
has been advised in writing by the registrant that the use of the Prospectus may
be resumed.

     11.  Future Registration Rights Agreements
          -------------------------------------

          Except for an underwriting agreement between the Company and one or
more professional underwriters of securities, the Company shall not agree to
register any Equity Securities under the Securities Act unless such agreement
specifically provides that:

                                     -23-
<PAGE>
 
          (a) the Holder of such Equity Securities may not participate in any
Demand Registration without the consent of the Holders of a majority of the
shares of the Restricted Stock included in such registration unless:

          (1) the offering of the Restricted Stock is to be a Firm Commitment
Underwritten Offering and the managing underwriter concludes that the public
offering or sale of such Equity Securities would not interfere with the
successful marketing of all Restricted Stock requested to be sold and

          (2) the Holders of Restricted Stock shall have the right to
participate, to the extent they may request, in any registration statement
initiated under a demand registration right exercised by the Holder of such
Equity Securities, except that if the managing underwriter of a public offering
made pursuant to such demand registration limits the number of shares of Equity
Securities to be sold, the participation of the Holders of the Restricted Stock
and the Holders of all other Equity Securities (other than the Equity Securities
held by such Holder of Equity Securities) shall be determined as set forth in
Section 3 hereof;

          (b) the holder of such Equity Securities may not participate in any
Piggyback Registration if the sale of Restricted Stock is to be underwritten
unless, if the managing underwriter limits the total number of shares to be
sold, the Holders of such Equity Securities and the Holder of Restricted Stock
are entitled to participate in such underwritten distribution based on the order
of priority set forth in Section 3 hereof, and

          (c) all Equity Securities excluded from any Registration as a result
of the foregoing limitations may not be publicly offered or sold for a period
(not to exceed at least 30 days prior to the effective date and 90 days
thereafter) that the managing underwriter reasonably determined is necessary in
order to effect the underwritten public offering of Restricted Stock registered
pursuant to this Agreement.

     12.  Miscellaneous
          -------------

          (a)  Remedies
               --------

          Each Holder of Restricted Stock, in addition to being entitled to
exercise all rights provided herein, and granted by law, including recovery of
damages, shall be entitled to specific performance of its rights under this
Agreement.  The Company agrees that monetary damages would not be adequate
compensation for any loss incurred by reason of a breach by it of the provisions
of this Agreement and hereby agrees to waive the defense in any action for
specific performance that a remedy at law would be adequate.

          (b)  Agreements; Entire Agreement
               ----------------------------

          The Company shall 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 of Restricted Stock in this Agreement or otherwise
conflicts with the provisions hereof.

Amended and Restated Registration Rights Agreement dated May 28, 1993 and the

by or among the parties, written or oral, that may have related in any way to
the subject matter hereof, including, without limitation, the Prior Agreements.

          (c)  Amendments and Waivers
               ----------------------

sentence, may not be amended, modified or supplemented, and waivers or consents
to departures from the provisions hereof may not be given unless the Company has
obtained the written consent of the Holders of at least 66% of the outstanding
shares of Restricted Stock; provided, that for so long as BofA or BFC holds any
Restricted Stock any waiver or amendment that would (i) nullify the underlying
purpose of this Agreement or (ii) adversely affect BFC or BofA, as the case may
be, vis a vis the other Investors on a proportionate basis shall not be made
without the prior written consent of BFC or BofA as applicable.  The foregoing
notwithstanding, a waiver or consent to departure from the provisions hereof
that relates exclusively to the rights of Holders of shares of Restricted Stock
whose shares are being sold pursuant to a Registration Statement and that does
not directly or indirectly affect the rights of other Holders of shares of
Restricted Stock may be given by the Holders of a majority of the shares of
Restricted Stock being sold.
