Item 3.  Source and Amount of Funds or Other Consideration

         On April 21, 1998, the three-way  business  combination  (the "Merger")
between WPL Holdings, Inc., a holding company incorporated under the laws of the
State of Wisconsin ("WPLH"), IES Industries Inc., a holding company incorporated
under the laws of the State of Iowa ("IES Industries"), and IPC, was consummated
in  accordance  with the terms of an Agreement  and Plan of Merger,  dated as of
November  10, 1996 (as amended on May 22, 1996 and August 16, 1996) by and among
WPLH,  IES  Industries  and IPC,  among  others.  In the  Merger,  WPLH,  as the
surviving holding company, changed its name to Interstate Energy Corporation and
is  currently  doing  business  as  Alliant  Corporation.  IEC is now the parent
holding  company of Wisconsin  Power and Light Company,  IES Utilities Inc., IPC
and Alliant.  Following the Merger,  IES Investments,  which prior to the Merger
was an indirect  wholly-owned  subsidiary  of IES  Industries,  continued  as an
indirect  wholly-owned  subsidiary of IEC as the surviving holding company. As a
result of the Merger,  IEC may be deemed to  beneficially  own the shares of the
Company's  Class A Common  Stock  held by IPC and IES  Investments.  IPC and IES
Investments continue as the record holders of such shares following the Merger.

Item 4.  Purpose of Transaction

         Shares of the Company's  Class A Common Stock were acquired by IEC as a
result of the Merger. IES Investments and IPC acquired the shares for investment
purposes.  The  acquisitions  were made prior to and not in connection  with the
Merger.

Item 5.  Interest in Securities of the Issuer

         (a)-(b) As of October 31,  1998,  IES  Investments  beneficially  owned
10,278,288  shares  of the  Company's  Class A Common  Stock,  which  represents
approximately  15.92% of the outstanding  shares of the Company's Class A Common
Stock.  Alliant,  as the direct parent  corporation of IES  Investments,  may be
deemed to  beneficially  own the shares of the  Company's  Class A Common  Stock
beneficially owned by IES Investments.

         As of October 31, 1998,  IPC  beneficially  owned 45,000  shares of the
Company's  Class A Common  Stock,  which  represents  approximately  .07% of the
outstanding shares of the Company's Class A Common Stock.

         IEC, as the parent holding  company of IES  Investments and IPC, may be
deemed to  beneficially  own the shares of the  Company's  Class A Common  Stock
beneficially  owned  by  IES  Investments  and  IPC,  all of  which  constitutes
10,323,288 shares of the Company's Class A Common Stock (approximately 15.99% of
the outstanding shares of the Company's Class A Common Stock).

         Each of the  executive  officers  and  directors of IEC,  Alliant,  IES
Investments  and IPC  beneficially  owns the  aggregate  number of shares of the
Company's Class A Common Stock set forth below after his or her name.  Except as
indicated  in the  footnotes,  the  persons  listed  below have sole  voting and
investment power over the shares beneficially owned. The shares

Item 6.  Contracts, Arrangements, Understandings or Relationships with Respect 
         to Securities of the Issuer.

         IES  Investments,  Clark E. McLeod and Mary E. McLeod,  Midwest Capital
Group, Inc. and MWR Investments Inc. (collectively, the "Investor Stockholders")
and the Company  have,  with respect to the  respective  shares of capital stock
owned by each such Investor  Stockholder,  entered into an investment agreement,
as amended (the  "Investor  Agreement"),  effective  as of June 10, 1996,  which
provides  that  each  Investor  Stockholder,   for  so  long  as  each  Investor
Stockholder  owns at least 10% of the  outstanding  capital stock of the Company
(but  in  no  event  longer  than  three   years),   shall  vote  such  Investor
Stockholder's  stock and take all action  within its power to: (i) establish the
size of the Board of Directors of the Company at nine  directors;  (ii) cause to
be elected to the Board of Directors of the Company one director  designated  by
IES  Investments  (for so  long as IES  Investments  owns  at  least  10% of the
outstanding  capital  stock of the  Company);  (iii)  cause to be elected to the
Board of  Directors of the Company one director  designated  by Midwest  Capital
Group, Inc. (for so long as Midwest Capital Group, Inc. owns at least 10% of the

of Directors of the Company three  directors  who are  executive  offices of the
Company  designated  by Clark E. McLeod (for so long as Clark E. McLeod and Mary

(v)  cause  to be  elected  to  the  Board  of  Directors  of the  Company  four
independent  directors  nominated  by the  Board  of  Directors  of the  Company
(subject to certain exceptions).

         On June 14, 1997, certain  shareholders of Consolidated  Communications
Inc.  ("CCI")  (collectively,  the  "CCI  Shareholders"),  the  Company  and the
Investor  Stockholders  entered into a Stockholders'  Agreement (as amended, the
"1997 Stockholders'  Agreement"),  which became effective on September 24, 1997.
Pursuant to the 1997 Stockholders' Agreement,  which amends and restates certain
agreements  contained in the Investor Agreement among the parties thereto,  each
Investor  Stockholder and the CCI  Shareholders,  for so long as each such party
owns at least 10% of the outstanding  Class A Common Stock,  shall, for a period
of three  years after the  effective  date of the 1997  Stockholders'  Agreement
(subject to certain  exceptions),  vote such party's  shares and take all action
within  its  power  to (i)  establish  the  size of the  Board  at up to  eleven
directors;  (ii) cause to be elected to the Board one director designated by IES
(for so long as IES owns at least 10% of the outstanding  Class A Common Stock);
(iii) cause to be elected to the Board one director  designated  by  MidAmerican
(for so long as MidAmerican owns at least 10% of the outstanding  Class A Common
Stock);  (iv) cause to be elected to the Board three directors who are executive
officers of the Company  designated by Clark E. McLeod (for so long as Clark and
Mary  McLeod  collectively  own at least 10% of the Class A Common  Stock);  (v)
cause  Richard  A.  Lumpkin  to be  elected to the Board (for so long as the CCI
Shareholders  collectively  own at least 10% of the  outstanding  Class A Common
Stock);  and (vi) cause to be elected to the Board four  non-employee  directors
nominated by the Board.  The 1997  Stockholders'  Agreement  also provides that,
until the earlier of the first  anniversary  of the  effective  date of the 1997
Stockholders' Agreement or March 31, 1999, and subject to certain exceptions, no
Investor  Stockholder or CCI Shareholder  will sell or otherwise  dispose of any
equity securities of the Company without the consent of the Board. In addition,

                                      -14-

<PAGE>



the  1997  Stockholders'  Agreement  provides  that if the  Company  grants  any
Investor  Stockholder or CCI  Shareholder  the  opportunity  to register  equity
securities of the Company  under the  Securities  Act of 1933,  the Company will
grant all other Investor  Stockholders and CCI Shareholders the same opportunity
to register  their pro rata portion of the Company  equity  securities  owned by
them. The other operative  provisions of the Investor Agreement remain unchanged
in the 1997 Stockholders' Agreement.

         On November 18, 1998, the former CCI Shareholders and certain permitted
transferees of such shareholders (collectively,  the "Former CCI Shareholders"),
the Company,  IES  Investments,  Clark E. McLeod,  Mary E. McLeod and Richard A.
Lumpkin,  entered  into  a  Stockholders'  Agreement  (the  "1998  Stockholders'
Agreement"),  which  supersedes,  as provided  therein,  the 1997  Stockholders'
Agreement. Pursuant to the 1998 Stockholders' Agreement, IES Investments,  Clark
E. McLeod, Mary E. McLeod and Richard A. Lumpkin  (collectively,  the "Principal
Stockholders"), for so long as each such party owns at least 4,000,000 shares of
the Class A Common  Stock,  shall,  for the period  ending on December 31, 2001,
vote such party's  shares and take all action  within its power to (i) establish
the size of the Board at up to eleven directors; (ii) cause to be elected to the
Board one director designated by IES (for so long as IES owns at least 4,000,000
shares of the Class A Common  Stock);  (iii)  cause to be  elected  to the Board
three directors who are executive officers of the Company designated by Clark E.
McLeod  (for so long as Clark  and Mary  McLeod  collectively  beneficially  and
continuously  own at least 4,000,000  shares of the Class A Common Stock);  (iv)
cause  Richard A.  Lumpkin to be elected to the Board (for so long as the Former
CCI   Shareholders  and  Richard  A.  Lumpkin   collectively   beneficially  and
continuously  own at least  4,000,000  shares of the Class A Common Stock);  (v)
cause to be elected to the Board a director  nominated by the Board to replace a
director designated by a Principal  Stockholder,  as provided above, because the
director no longer can or will serve as a director; and (vi) cause to be elected
to the Board up to six non-employee  directors  nominated by the Board. The 1998
Stockholders'  Agreement  provides  that until  December 31,  2001,  IES and its
affiliates  will not  directly or  indirectly  acquire  any Company  securities,
except as permitted by the 1998 Stockholders'  Agreement. The 1998 Stockholders'
Agreement further provides that, until December 31, 2001, and subject to certain
exceptions,  no  Principal  Stockholder  will sell or  otherwise  dispose of any
equity  securities of the Company without the consent of the Board. In addition,
the  Stockholders'  Agreement  provides that if the Company grants any Principal
Stockholder the  opportunity to register equity  securities of the Company under
the  Securities  Act of  1933,  the  Company  will  grant  all  other  Principal
Stockholders  the same  opportunity  to register  their pro rata  portion of the
Company  equity  securities  owned  by  them.   Certain  sections  of  the  1997
Stockholders'  Agreement are  superseded on the terms  contemplated  in the 1998
Stockholders' Agreement.

         On January 7, 1999, the former CCI Shareholders  and certain  permitted
transferees of such shareholders (collectively,  the "Former CCI Shareholders"),
the  Company,  IES  Investments,  Clark E. McLeod,  Mary E.  McLeod,  Richard A.
Lumpkin and M/C  Investors  LLC and  Media/Communications  Partners  III Limited
Partnership (collectively, the "New Stockholders"), entered into a Stockholders'
Agreement (the "1999 Stockholders'  Agreement").  IES Investments,  the McLeods,
Lumpkin and the Former CCI  Shareholders  are  referred to  collectively  as the
"1998  Stockholders."  Pursuant to the 1999 Stockholders'  Agreement,  each 1998
Stockholder,  for so long as each such party owns at least  4,000,000  shares of
the Class A Common  Stock,  shall,  for the period  ending on December 31, 2001,
vote

                                      -15-

such party's  shares and take all action  within its power to (i)  establish the
size of the Board at up to eleven  directors;  (ii)  cause to be  elected to the
Board one director  designated by the New  Stockholders  (for so long as the New
Stockholders own at least 2,500,000  shares of the Class A Common Stock);  (iii)
cause to be elected to the Board a director  nominated by the Board to replace a
director  designated by the New Stockholders,  as provided above; (iv) establish
and maintain the size of the Board at up to eleven  directors;  and (v) cause to
be  elected  to the Board up to five  non-employee  directors  nominated  by the
Board. Pursuant to the 1999 Agreement, the New Stockholders, for so long as they
collectively  and  continuously  own at least 2,500,000 shares of Class A Common
Stock,  shall, for the period ending on December 31, 2001, vote their shares and
take all action with their power to (i)  establish  and maintain the size of the
Board at up to  eleven  directors;  (ii)  cause to be  elected  to the Board one
director  designated by IES Investments  (for so long as IES Investments owns at
least  4,000,000  shares of Class A Common Stock);  (iii) cause to be elected to
the Board three directors who are executive  officers of the Company  designated
by  Clark  E.  McLeod  (for  so long  as  Clark  and  Mary  McLeod  collectively
beneficially  and  continuously  own at least  4,000,000  shares  of the Class A
Common Stock);  (iv) cause Richard A. Lumpkin to be elected to the Board (for so
long  as the  Former  CCI  Shareholders  and  Richard  A.  Lumpkin  collectively
beneficially  and  continuously  own at least  4,000,000  shares  of the Class A
Common Stock);  (v) cause to be elected to the Board a director nominated by the
Board to replace a director designated by a Principal  Stockholder,  as provided
above,  because the  director  no longer can or will serve as a  director;  (vi)
cause to be elected to the Board up to five non-employee  directors nominated by
the Board; and (vii) cause to be elected to the Board one director designated by
the  New  Stockholders  (for  so  long  as  the  New  Stockholders  collectively
beneficially  and  continuously  own at least 2,500,000 shares of Class A Common
Stock). The 1999  Stockholders'  Agreement further provides that, until December
31, 2001, and subject to certain  exceptions,  no New  Stockholder  will sell or
otherwise dispose of any equity securities of the Company without the consent of
the Board. In addition,  the 1999  Stockholders'  Agreement provides that if the
Company grants any Principal  Stockholder  the  opportunity  to register  equity
securities of the Company  under the  Securities  Act of 1933,  the Company will
grant all other Principal  Stockholders  the same  opportunity to register their
pro rata portion of the Company equity securities owned by them.

                     director or directors  designated  by such party or parties
                     to tender their  immediate  resignation  to the Board which
                     the Board may accept or reject; and

                     the Board, up to six (6) non-employee directors;

provided, however, notwithstanding any other provision of this Agreement, if any
Principal Stockholder hereto would not be entitled to have a director elected to
the  Board  with  respect  to such  Principal  Stockholder  under  the  Original
Stockholders'  Agreement but would be entitled to have a director elected to the
Board with respect to such Principal Stockholder pursuant to Section 1.1 of this
Agreement  except that the Voting  Agreement  Effective  Date  hereunder has not
occurred,  then this Agreement  shall be applied with respect to the election of
the director of such Principal  Stockholder as if the Voting Agreement Effective
Date has occurred and each party hereto shall act under this  Agreement to cause
the election of the director of such Principal Stockholder.

       The parties hereto agree that Section 1.1 and Section 1.2 of the Original
Stockholders'  Agreement  shall  terminate  and be of no  force or  effect  with
respect to the rights and  obligations  of the parties hereto amongst each other
as of the Voting Agreement  Effective Date. For purposes of Section 1.1, Lumpkin
and all of the  CCI  Shareholders  shall  be  deemed  to be a  single  Principal
Stockholder,  and a CCI Shareholder shall be deemed to own shares "continuously"
as long as the shares of such CCI  Shareholder are owned by such CCI Shareholder
or by a CCI Permitted Transferee (as defined in Section 3.1).

3. TRANSFERS OF SECURITIES

       3.1    Restrictions on Transfers

              (a) Except as  otherwise  provided in this  Section 3.1 or Section
3.2,  each  Principal   Stockholder  hereby  severally  agrees  that  until  the
Expiration Date, such Principal  Stockholder will not offer,  sell,  contract to
sell,  grant any option to  purchase,  or  otherwise  dispose  of,  directly  or
indirectly,  ("Transfer"),  any equity  securities  of the  Company or any other
securities   convertible   into  or  exercisable  for  such  equity   securities
("Securities")   beneficially  owned  by  such  Principal   Stockholder  without
submitting a written request to, and receiving the prior written consent of, the
Board of Directors,  provided,  however,  that any CCI  Shareholder may transfer
Securities to any other CCI Shareholder,  the spouse of a CCI Shareholder,  or a
lineal  descendant of a CCI  Shareholder  (or a trust for the primary benefit of
any one or more of a CCI  Shareholder,  the  spouse of a CCI  Shareholder,  or a
lineal  descendant of a CCI  Shareholder or a partnership  or limited  liability
company owned and managed solely by one or more CCI Shareholders, spouses of CCI
Shareholders and lineal descendants of CCI  Shareholders),  or, in the case of a
CCI  Shareholder  that is a trust,  to any beneficiary of such trust (or a trust
for the  primary  benefit  of  such  beneficiary  or a  partnership  or  limited
liability  company  owned and  managed  solely by one or more CCI  Shareholders,
spouses of CCI Shareholders and lineal descendants of CCI Shareholders), in each
case provided  that (i) such  transfer is done in  accordance  with the transfer
restrictions  applicable to such Securities  under federal and state  securities
laws and (ii) the  transferee  agrees  to be  bound  by the  terms  hereof  as a
Principal  Stockholder with respect to the shares being transferred  pursuant to
this  Section,  and any such  transfer  shall not  constitute a  "Transfer"  for
purposes of this Agreement (any such CCI transferee  pursuant to this proviso, a
"CCI Permitted  Transferee").  In the event that the Board of Directors consents
to any Transfer of Securities by a Principal Stockholder pursuant to the written
request of such Principal Stockholder (a "Transferring  Stockholder") and except
as otherwise  provided in Section  3.1(b) and Section 3.2, each other  Principal
Stockholder shall, 


                                      -5-
<PAGE>

notwithstanding  the  provisions  of this  Section  3.1(a),  have  the  right to
Transfer a percentage  of the total number of Securities  beneficially  owned by
such  Principal  Stockholder  equal to the  percentage  of the  total  number of
Securities beneficially owned by the Transferring  Stockholder that the Board of
Directors has consented may be Transferred by such Transferring Stockholder. The
parties  acknowledge that any Transfer  pursuant to this Section 3.1(a) to which
the Board of Directors has consented may be in connection with, or as part of, a
private  placement  by the  Company  of,  or other  transaction  involving,  its
Securities.

              (b) In addition to the  provisions of Section  3.1(a),  commencing
for the quarter ending December 31, 1998 and ending on the Expiration  Date, the
Board shall determine prior to the public release of the Company's  consolidated
financial results with respect to the end of each financial  reporting  quarter,
the aggregate  number,  if any, of shares of Class A Common Stock (not to exceed
in the aggregate one hundred fifty thousand  (150,000)  shares of Class A Common
Stock per quarter,  subject to  adjustment  pursuant to Section 5.1) that may be
Transferred by the Principal  Stockholders  (the "Transfer  Amount")  during the
period commencing on the third (3rd) business day and ending on the twenty-third
(23rd) business day following such public release of the Company's  quarterly or
annual financial results or such other trading period designated or permitted by
the Board with  respect to the purchase  and sale of its  Securities  (each such
period, a "Transfer Period").  Notwithstanding the provisions of Section 3.1(a),
each Principal  Stockholder  shall be entitled to Transfer  during each Transfer
Period,  provided such Transfer is effected in  accordance  with all  applicable
federal and state  securities  laws,  a number of shares of Class A Common Stock
equal to thirty-three and one-third percent (33 1/3%) of the Transfer Amount, if
any,  for such  Transfer  Period  (rounding  down in the case of any  fractional
amount). Any portion of any Principal Stockholder's share of the Transfer Amount
that such Principal  Stockholder elects not to transfer during a Transfer Period
shall be  reallocated  equally among the remaining  Principal  Stockholders  who
intend to Transfer  shares of Class A Common Stock during such Transfer  Period,
and such  remaining  Principal  Stockholders  shall be entitled to Transfer such
additional  shares of Class A Common Stock during the Transfer Period,  provided
such Transfer is effected in accordance  with all  applicable  federal and state
securities  laws. In no event shall any portion of a Transfer Amount that is not
utilized by a Principal  Stockholder  during a Transfer Period be reallocated or
otherwise credited to any subsequent  Transfer Periods.  The parties acknowledge
that the Company has determined that the Transfer Amount that may be Transferred
by the Principal  Stockholders  during the Transfer Period for the quarter ended
September 30, 1998 pursuant to this Section  3.1(b) shall be an aggregate of one
hundred fifty thousand (150,000) shares of Class A Common Stock.

              (c) Commencing for the quarter ending December 31, 1998 and ending
on the Expiration Date, the Company shall give each Principal Stockholder prompt
written  notice  (in any  event no  later  than  fifty  (50)  days  prior to the



                                      -6-
<PAGE>

beginning  of  the  applicable  Transfer  Period)  of its  determination  of any
Transfer Amount.  Within seven (7) days of receipt of such notice, any Principal
Stockholder  that desires to Transfer shares of Class A Common Stock during such
Transfer  Period  pursuant to Section 3.1(b) shall provide written notice to the
Company of the number of shares such Principal  Stockholder desires to Transfer.
Not later than seven (7) days after receipt of such responses, the Company shall
notify all  remaining  Principal  Stockholders  of any  Principal  Stockholder's
election not to Transfer the total number of shares of Class A Common Stock that
such Principal  Stockholder is entitled to Transfer during such Transfer Period.
Any Principal  Stockholder that desires to Transfer additional shares of Class A
Common Stock equal to all or part of the remaining  Transfer Amount shall notify
the Company within seven (7) days of receipt of the Company's second notice. The
Company shall  allocate the  remaining  Transfer  Amount in accordance  with the
provisions  of  Section  3.1(b)  and  shall  notify  the  appropriate  Principal
Stockholders  of such  allocation  no  later  than ten  (10)  days  prior to the
beginning of the Transfer Period.

              (d) For purposes of this  Section 3.1,  Lumpkin and all of the CCI
Shareholders shall be deemed to be a single Principal Stockholder.

       3.2    Registration Rights

              (a) In the event that the Board of Directors  consents pursuant to
Section  3.1(a) to a  Principal  Stockholder's  request  for a  Transfer  and in
connection therewith,  the Company agrees to register Securities with respect to
such Transfer  under the  Securities  Act of 1933,  as amended (the  "Securities
Act"), the Company shall grant each other Principal  Stockholder the opportunity
(subject to reduction in the event the registered  Transfer is  underwritten) to
register for Transfer  under the Securities Act a percentage of the total number
of Securities  beneficially  owned by such  Principal  Stockholder  equal to the
percentage  of  the  total  number  of  Securities  beneficially  owned  by  the
Transferring  Stockholder that such Transferring  Stockholder is registering for
Transfer  under the  Securities  Act,  on the same terms and  conditions  as the
Transferring Stockholder (each Principal Stockholder registering,  or indicating
a desire to register,  any  Securities  for Transfer  under the  Securities  Act
pursuant to this Section 3.2 being a "Registering Transferor").

              (b) To the extent  that the  Company  grants  pursuant  to Section
3.1(b) a Principal  Stockholder  the  opportunity to register  shares of Class A
Common Stock for Transfer under the Securities Act, the Company shall grant each
other Principal  Stockholder the opportunity  (subject to reduction in the event
the registered  Transfer is  underwritten) to register an equal number of shares
of Class A Common Stock for Transfer  under the Securities Act on the same terms
and conditions.

              (c) In the event the Company  proposes  to register  any shares of
Class A Common  Stock  under the  Securities  Act  pursuant  to an  underwritten


                                      -7-
<PAGE>


primary offering (other than pursuant to a registration statement on Form S-4 or
Form S-8 or any successor forms thereto or other form which would not permit the
inclusion of the shares of Class A Common Stock of the Principal  Stockholders),
the Company, as determined by the Board of Directors,  shall give written notice
to all Principal  Stockholders  of its intention to effect such a  registration.
Following any such notice,  the Board of Directors  shall undertake to determine
the  aggregate  number,  if any,  of shares of Class A Common  Stock held by the
Principal  Stockholders  (not to exceed in the  aggregate  on a per year basis a
number of shares of Class A Common Stock equal to fifteen  percent  (15%) of the
total  number  of  shares  of Class A  Common  Stock  beneficially  owned by the
Principal  Stockholders as of December 31, 1998, subject to adjustment  pursuant
to Section 5.1) to be registered by the Company  under the  Securities  Act (the
"Registrable  Amount") for Transfer by the Principal  Stockholders in connection
with such offering. If the Board determines to register shares of Class A Common
Stock held by the Principal  Stockholders  pursuant to this Section 3.2(c),  the
Company will promptly give written notice of such determination to all Principal
Stockholders, and thereupon the Company will use commercially reasonable efforts
to effect the  registration of that portion of the  Registrable  Amount that the
Registering  Transferors  indicate  a  desire  to  register.  In the  event  the
Registering  Transferors  indicate  a desire to  register  a number of shares of
Class A Common Stock that, in the aggregate, exceeds the Registrable Amount, the
number of shares of Class A Common Stock that each Registering  Transferor shall
be entitled to register  shall be reduced to the extent such number exceeds such
Registering Transferor's pro rata share of the Registrable Amount based upon the
ratio of the total number of Securities  beneficially  owned by such Registering
Transferor to the total number of Securities beneficially owned by all Principal
Shareholders.  To the  extent  any  portion of the  Registrable  Amount  remains
unallocated after such reductions, each Registering Transferor who has indicated
a desire to register additional shares of Class A Common Stock shall be entitled
to  register  an  additional  amount  of  Class A  Common  Stock  equal  to such
Registering  Transferor's pro rata portion of the remaining  Registrable  Amount
based upon the ratio of the total  number of  Securities  beneficially  owned by
such Registering Transferor to the total number of Securities beneficially owned
by  all  Registering  Transferors  who  have  indicated  a  desire  to  register
additional shares of Class A Common Stock. The reallocation  procedure described
in the preceding  sentence shall be repeated until the entire Registrable Amount
is allocated. All terms, conditions and rights with respect to such registration
(including  but not  limited  to any  determination  to reduce  the  Registrable
Amount) shall be determined by the Board,  provided that (i) the representations
and  warranties  of a  Principal  Stockholder  shall be  customary  taking  into
account,  among other  things,  the nature of the  offering  and such  Principal
Stockholder's  relationship  with the  Company,  and (ii) the  Company  shall be
responsible  for all  expenses  with  respect  to such  registration  other than
underwriting  discounts and commissions allocable to the Class A Common Stock of
the Registering Transferors,  which underwriting discounts and commissions shall
be the responsibility of the Registering Transferors.

              (d) In addition to the  registration  rights  granted  pursuant to
Sections  3.2(a),  (b) and (c), no more  frequently than once during each of the
calendar  years  ending  December 31,  1999,  2000 and 2001 (each such year,  an
"Annual Period"), and upon either (i) the receipt of a written request of one or
more Principal  Stockholders or (ii) a determination  by the Board of Directors,
the Board shall  undertake  to determine  the  Registrable  Amount,  if any, for
Transfer by the  Principal  Stockholders.  If the Board  determines  to register
shares of Class A Common Stock held by the  Principal  Stockholders  pursuant to
this Section  3.2(d),  the Company  will  promptly  give written  notice of such
determination to all Principal Stockholders,  and thereupon the Company will use
commercially  reasonable  efforts to effect the  registration of that portion of
the  Registrable  Amount that the Registering  Transferors  indicate a desire to
register. In the event the Registering Transferors indicate a desire to register
a number of shares of Class A Common Stock that, in the  aggregate,  exceeds the
Registrable  Amount,  the  number of shares  of Class A Common  Stock  that each
Registering  Transferor  shall be entitled  to register  shall be reduced to the
extent such number exceeds such  Registering  Transferor's pro rata share of the
Registrable  Amount  based  upon the  ratio of the total  number  of  Securities
beneficially  owned  by such  Registering  Transferor  to the  total  number  of
Securities beneficially owned by all Principal  Stockholders.  To the extent any
portion of the Registrable  Amount remains  unallocated  after such  reductions,
each  Registering  Transferor who has indicated a desire to register  additional
shares of Class A Common  Stock shall be  entitled  to  register  an  additional
amount of Class A Common Stock equal to such  Registering  Transferor's pro rata
portion of the  remaining  Registrable  Amount based upon the ratio of the total
number of Securities  beneficially  owned by such Registering  Transferor to the
total number of Securities beneficially owned by all Registering Transferors who
have indicated a desire to register  additional  shares of Class A Common Stock.
The reallocation procedure described in the preceding sentence shall be repeated
until the entire  Registrable  Amount is allocated.  All terms,  conditions  and
rights  with  respect to such  registration  (including  but not  limited to any
determination  to reduce the  Registrable  Amount)  shall be  determined  by the
Board,  provided  that (i) the  representations  and  warranties  of a Principal
Stockholder  shall be customary  taking into account,  among other  things,  the
nature of the offering and such Principal  Stockholder's  relationship  with the
Company, and (ii) the Company shall be responsible for all expenses with respect
to such registration  other than underwriting  discounts and commissions,  which
underwriting  discounts  and  commissions  shall  be the  responsibility  of the
Registering Transferors.

              (e) If the Board  establishes a committee (a "Pricing  Committee")
to  authorize  and  approve  the price and any other  terms of any  Transfer  of
Securities  registered  under the Securities Act pursuant to this Section 3.2 in
which  Lumpkin  or  any  CCI  Shareholder  is  participating  as  a  Registering
Transferor,  the  Company  will use its best  efforts  to  cause  Lumpkin  to be
nominated to such Pricing

Committee.  Notwithstanding any other provision of this Agreement, to the extent
the Company has undertaken to register Securities of the Principal  Stockholders
pursuant to this  Section  3.2, the Company may  subsequently  determine  not to
register such  Securities  and may either not file a  registration  statement or
otherwise  withdraw or abandon a registration  statement  previously  filed with
respect to the registration of such Securities.

              (f) For purposes of this  Section 3.2,  Lumpkin and all of the CCI
Shareholders shall be deemed to be a single Principal Stockholder.

           3.1   Restrictions on Transfers

              (a) Except as  otherwise  provided in this  Section 3.1 or Section
3.2, the New  Stockholders  hereby agree that until the Expiration Date, the New


                                      -5-
<PAGE>

Stockholders  will not  offer,  sell,  contract  to sell,  grant  any  option to
purchase,  or otherwise  dispose of, directly or indirectly,  ("Transfer"),  any
equity  securities of the Company or any other  securities  convertible  into or
exercisable for such equity securities ("Securities") beneficially owned by such
New  Stockholders  as  a  result  of  the  Merger  (including  distributions  of
Securities with respect to such  Securities and Securities  acquired as a result
of a stock split with respect to such Securities)  without  submitting a written
request to, and receiving the prior written  consent of, the Board of Directors;
provided,  however,  that  a New  Stockholder  may  transfer  Securities  to any
beneficial  owner or Affiliate of such New  Stockholder,  in each case  provided
that (i) such  transfer is done in  accordance  with the  transfer  restrictions
applicable to such Securities  under federal and state  securities laws and (ii)
the transferee  agrees to be bound by the terms hereof as a New Stockholder with
respect to the shares being  transferred  pursuant to this Section (any such New
Stockholder  transferee  pursuant to this proviso, a "New Stockholder  Permitted
Transferee"),  and any such  transfer  shall not  constitute  a  "Transfer"  for
purposes of this Agreement. Notwithstanding the foregoing, no party hereto shall
avoid the provisions of this Agreement by making one or more transfers to one or
more New  Stockholder  Permitted  Transferees  and then  disposing of all or any
portion  of  such  party's  interest  in  any  such  New  Stockholder  Permitted
Transferee. In the event that the Board of Directors consents to any Transfer of
Securities by a Principal Stockholder (for purposes of this Agreement,  the term
"Principal  Stockholder" shall have the same meaning as ascribed to such term in
the 1998  Stockholders'  Agreement)  pursuant  to the  written  request  of such
Principal  Stockholder (the  "Transferring  Principal  Stockholder")  during the
period  commencing  on  January 1, 2000 and  ending on the  Expiration  Date and
except as  otherwise  provided  in  Section  3.1(b)  and  Section  3.2,  the New
Stockholders shall  notwithstanding  the provisions of this Section 3.1(a), have
the  right  to  Transfer  a  percentage   of  the  total  number  of  Securities
beneficially  owned by the New Stockholders equal to the percentage of the total
number  of  Securities   beneficially   owned  by  the  Transferring   Principal
Stockholder that the Board of Directors has consented may be Transferred by such
Transferring Principal Stockholder. In the event the Board of Directors consents
to any Transfer of  Securities by the New  Stockholders  pursuant to the written
request of the New  Stockholders  (the  "Transferring  New  Stockholders"),  and
except as  otherwise  provided  in Section  3.1(b) and  Section  3.2 of the 1998
Stockholders' Agreement,  each Principal Stockholder shall,  notwithstanding the
provisions of Section 3.1(a) of the 1998 Stockholders' Agreement, have the right
to Transfer a percentage of the total number of Securities beneficially owned by
such  Principal  Stockholder  equal to the  percentage  of the  total  number of
Securities  beneficially  owned by the Transferring  New  Stockholders  that the
Board of Directors has consented may be  Transferred  by such  Transferring  New
Stockholders.

              (b) In  addition  to the  provisions  of Section  3.1(a),  for the
period  commencing  for the quarter  ending  December 31, 1999 and ending on the
Expiration  Date, the Board shall  determine  prior to the public release of the


                                      -6-
<PAGE>

Company's  consolidated  financial  results with respect to each such  financial
reporting quarter during such period, the aggregate number, if any, of shares of
Class A Common Stock (not to exceed in the  aggregate  fifty  thousand  (50,000)
shares of Class A Common Stock per quarter,  subject to  adjustment  pursuant to
Section 5.1) that may be  Transferred  by the New  Stockholders  (the  "Transfer
Amount") during the period commencing on the third (3rd) business day and ending
on the  twenty-third  (23rd)  business day following  such public release of the
Company's  quarterly or annual  financial  results or such other trading  period
designated  or  permitted  by the Board with respect to the purchase and sale of
its Securities  (each such period,  a "Transfer  Period").  Notwithstanding  the
provisions of Section 3.1(a), the New Stockholders shall be entitled to Transfer
during each  Transfer  Period,  provided such Transfer is effected in accordance
with all  applicable  federal and state  securities  laws, a number of shares of
Class A Common Stock equal to the  Transfer  Amount,  if any, for such  Transfer
Period.  In no event shall any portion of a Transfer Amount that is not utilized
by the New  Stockholders  during a Transfer  Period be  reallocated or otherwise
credited to any  subsequent  Transfer  Periods.  Notwithstanding  the  foregoing
provisions of this Section  3.1(b),  to the extent that the Company  permits the
Principal  Stockholders  the  opportunity  to Transfer  shares of Class A Common
Stock pursuant to Section 3.1(b) of the 1998 Stockholders'  Agreement during the
period  commencing  on January 1, 2000 and ending on the  Expiration  Date,  the
Company shall grant the New Stockholders the opportunity to Transfer on the same
terms and  conditions  a number of shares of Class A Common  Stock  equal to the
number of shares  which each  Principal  Stockholder  is  entitled  to  Transfer
pursuant to such Section 3.1(b), without considering those provisions of Section
3.1(b) of the 1998  Stockholders'  Agreement  relating  to the  reallocation  of
amounts among the Principal  Stockholders.  To the extent the Board determines a
Transfer Amount with respect to the New Stockholders for any particular quarter,
the Board shall determine an equal Transfer Amount for such quarter with respect
to  each  Principal   Stockholder   pursuant  to  Section  3.1(b)  of  the  1998
Stockholders' Agreement.

              (c) For the period  commencing for the quarter ending December 31,
1999  and  ending  on the  Expiration  Date,  the  Company  shall  give  the New
Stockholders  prompt  written notice (in any event no later than fifty (50) days
prior to the beginning of the applicable  Transfer Period) of its  determination
of any Transfer Amount. Within seven (7) days of receipt of such notice, the New
Stockholders shall provide written notice to the Company of the number of shares
of Class A Common Stock that the New Stockholders desire to Transfer pursuant to
Section 3.1(b).

              (d) During the year ending  December 31,  1999,  to the extent the
Company  participates  in a strategic  transaction  with an outside  investor(s)
pursuant  to which such  investor(s)  acquires  Securities  of the  Company at a
premium to the then average trading price of the Company's Securities, and after
the Company has been paid or otherwise  received its  consideration  or proceeds
from 


                                      -7-
<PAGE>

such  transaction as determined by the Company,  the Principal  Stockholders and
the New Stockholders may be entitled to participate in such transaction on a pro
rata basis as determined by the Board of Directors.

              (e) For purposes of this Section 3.1, the New  Stockholders  shall
be deemed to be a single stockholder of the Company,  and Lumpkin and all of the
CCI Shareholders shall be deemed to be a single Principal Stockholder.

       3.2    Registration Rights

              (a) In the event that the Board of Directors  consents pursuant to
Section 3.1(a) of the 1998 Stockholders'  Agreement to a Principal Stockholder's
request  for a  Transfer  during the  period  commencing  on January 1, 2000 and
ending on the Expiration Date and in connection therewith, the Company agrees to
register  Securities  with respect to such Transfer  under the Securities Act of
1933,  as amended  (the  "Securities  Act"),  the  Company  shall  grant the New
Stockholders  the opportunity  (subject to reduction in the event the registered
Transfer is  underwritten)  to register for Transfer  under the Securities Act a
percentage  of the total  number  of  Securities  beneficially  owned by the New
Stockholders  equal  to  the  percentage  of  the  total  number  of  Securities
beneficially  owned  by  the  Transferring   Principal   Stockholder  that  such
Transferring  Principal  Stockholder  is  registering  for  Transfer  under  the
Securities Act, on the same terms and conditions as the  Transferring  Principal
Stockholder.  In the event  that the Board of  Directors  consents  pursuant  to
Section  3.1(a)  of  this  Agreement  to the  New  Stockholders'  request  for a
Transfer,  and in connection therewith the Company agrees to register Securities
with respect to such Transfer under the Securities  Act, the Company shall grant
each Principal  Stockholder pursuant to Section 3.1(a) of the 1998 Stockholders'
Agreement  the  opportunity  (subject to reduction  in the event the  registered
Transfer is  underwritten)  to register for Transfer  under the Securities Act a
percentage  of the  total  number  of  Securities  beneficially  owned  by  such
Principal  Stockholder equal to the percentage of the total number of Securities
beneficially  owned by the Transferring New Stockholders  that such Transferring
New Stockholders are registering under the Securities Act, on the same terms and
conditions as the Transferring New Stockholders.

              (b) To the extent  that the  Company  grants  pursuant  to Section
3.1(b)  of  the  1998  Stockholders'   Agreement  a  Principal  Stockholder  the
opportunity  to register  shares of Class A Common Stock for Transfer  under the
Securities Act during the period commencing on January 1, 2000 and ending on the
Expiration  Date, the Company shall grant the New  Stockholders  the opportunity
(subject to reduction in the event the registered  Transfer is  underwritten) to
register an equal number of shares of Class A Common  Stock for  Transfer  under
the Securities Act on the same terms and conditions,  without  considering those
provisions of Section 3.1(b) of the 1998 Stockholders' Agreement relating to the
reallocation of amounts among the Principal Stockholders. To the extent that the
Company grants 


                                      -8-
<PAGE>

pursuant  to  Section  3.1(b)  of  this  Agreement  the  New   Stockholders  the
opportunity  to register  shares of Class A Common Stock for Transfer  under the
Securities Act, the Company shall grant each Principal  Stockholder  pursuant to
Section 3.1(b) of the 1998 Stockholders'  Agreement the opportunity  (subject to
reduction in the event the registered  Transfer is  underwritten) to register an
equal number of shares of Class A Common Stock for Transfer under the Securities
Act on the same terms and conditions.

              (c) For the period commencing on January 1, 2000 and ending on the
Expiration  Date,  in the event the Company  proposes to register  any shares of
Class A Common  Stock  under the  Securities  Act  pursuant  to an  underwritten
primary offering (other than pursuant to a registration statement on Form S-4 or
Form S-8 or any successor forms thereto or other form which would not permit the
inclusion  of the shares of Class A Common Stock of the New  Stockholders),  the
Company,  as determined by the Board of Directors,  shall give written notice to
the New  Stockholders of its intention to effect such a registration.  Following
any such  notice,  the Board of  Directors  shall  undertake  to  determine  the
aggregate  number,  if any,  of shares of Class A Common  Stock  held by the New
Stockholders  (not to exceed in the  aggregate  on a per year  basis a number of
shares  of Class A Common  Stock  equal to  fifteen  percent  (15%) of the total
number  of  shares  of  Class  A  Common  Stock  beneficially  owned  by the New
Stockholders as of the Effective Date) to be registered by the Company under the
Securities Act (the  "Registrable  Amount") for Transfer by the New Stockholders
in connection with such offering during such period.  If the Board determines to
register shares of Class A Common Stock held by the New Stockholders pursuant to
this Section  3.2(c),  the Company  will  promptly  give written  notice of such
determination  to the New  Stockholders,  and  thereupon  the  Company  will use
commercially  reasonable  efforts to effect the  registration of that portion of
the Registrable Amount that the New Stockholders  indicate a desire to register.
All terms,  conditions and rights with respect to such  registration  (including
but not limited to any determination to reduce the Registrable  Amount) shall be
determined by the Board, provided that (i) the representations and warranties of
the New Stockholders shall be customary taking into account, among other things,
the  nature of the  offering  and the New  Stockholders'  relationship  with the
Company, and (ii) the Company shall be responsible for all expenses with respect
to such registration other than underwriting discounts and commissions allocable
to the  Class  A  Common  Stock  of the  New  Stockholders,  which  underwriting
discounts and commissions  shall be the  responsibility of the New Stockholders.
Notwithstanding  the foregoing  provisions of this Section 3.2(c), to the extent
that the Company  grants  pursuant to Section  3.2(c) of the 1998  Stockholders'
Agreement the Principal Stockholders the opportunity to register shares of Class
A Common  Stock  for  Transfer  under  the  Securities  Act  during  the  period
commencing  on January 1, 2000 and ending on the  Expiration  Date,  the Company
shall grant the New  Stockholders  the opportunity to register shares of Class A
Common Stock on a  substantially  similar basis.  To the extent that the Company
grants  pursuant to Section  3.2(c) of this Agreement the New 


                                      -9-

Stockholders  the  opportunity  to register  shares of Class A Common  Stock for
Transfer  under the  Securities  Act,  the Company  shall  grant each  Principal
Stockholder  pursuant to Section 3.2(c) of the 1998 Stockholders'  Agreement the
opportunity  to  register  shares  of  Class A Common  Stock on a  substantially
similar basis.

              (d) In addition to the  registration  rights  granted  pursuant to
Sections  3.2(a),  (b) and (c), no more  frequently than once during each of the
calendar  years ending  December  31, 2000 and 2001 (each such year,  an "Annual
Period"),  and upon  either  (i) the  receipt  of a written  request  of the New
Stockholders or (ii) a determination by the Board of Directors,  the Board shall
undertake to determine the Registrable  Amount,  if any, for Transfer by the New
Stockholders. If the Board determines to register shares of Class A Common Stock
held by the New Stockholders  pursuant to this Section 3.2(d),  the Company will
promptly give written notice of such determination to the New Stockholders,  and
thereupon  the Company will use  commercially  reasonable  efforts to effect the
registration of that portion of the Registrable Amount that the New Stockholders
indicate a desire to register. All terms,  conditions and rights with respect to
such registration  (including but not limited to any determination to reduce the
Registrable  Amount)  shall be  determined  by the Board,  provided that (i) the
representations and warranties of the New Stockholders shall be customary taking
into  account,  among  other  things,  the  nature of the  offering  and the New
Stockholders'  relationship  with the  Company,  and (ii) the  Company  shall be
responsible  for all  expenses  with  respect  to such  registration  other than
underwriting  discounts and commissions allocable to the Class A Common Stock of
the New Stockholders,  which underwriting discounts and commissions shall be the
responsibility of the New Stockholders. Notwithstanding the foregoing provisions
of this  Section  3.2(d),  to the extent  that the  Company  grants  pursuant to
Section 3.2(d) of the 1998  Stockholders'  Agreement the Principal  Stockholders
the  opportunity  to register  shares of Class A Common Stock for Transfer under
the Securities Act during the period commencing on January 1, 2000 and ending on
the  Expiration   Date,  the  Company  shall  grant  the  New  Stockholders  the
opportunity  to  register  shares  of  Class A Common  Stock on a  substantially
similar basis.  To the extent that the Company grants pursuant to Section 3.2(d)
of this Agreement the New  Stockholders  the  opportunity to register  shares of
Class A Common Stock for Transfer  under the  Securities  Act, the Company shall
grant  each  Principal  Stockholder  pursuant  to  Section  3.2(d)  of the  1998
Stockholders'  Agreement the  opportunity  to register  shares of Class A Common
Stock on a substantially similar basis.

              (e) For purposes of this Section 3.2, the New  Stockholders  shall
be deemed to be a single stockholder of the Company,  and Lumpkin and all of the
CCI Shareholders shall be deemed to be a single Principal Stockholder.

              (f) Notwithstanding any other provision of this Agreement,  to the
extent the Company has undertaken to register Securities of the New Stockholders


                                      -10-
<PAGE>

pursuant to this  Section  3.2, the Company may  subsequently  determine  not to
register such  Securities  and may either not file a  registration  statement or
otherwise  withdraw or abandon a registration  statement  previously  filed with
respect to the registration of such Securities;  provided that to the extent the
Principal  Stockholders  are also  participating in such  registration,  the New
Stockholders and the Principal  Stockholders  will be treated on a substantially
similar basis with respect to any such determination not to register  Securities
or the withdrawal or abandonment of a registration statement previously filed as
contemplated by this Section 3.2(f).

respective  signatures of, or on behalf of, all of the parties hereto. It is the
express understanding of the parties hereto that this Agreement shall be binding
and enforceable with respect to the parties hereto on the terms herein set forth
