                         Pursuant to Section 151 of the
                General Corporation Law of the State of Delaware

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

   IXC Communications, Inc. (the "Company"), a corporation organized and
existing under the General Corporation Law of the State of Delaware, does
hereby certify that, pursuant to authority conferred upon the board of
directors of the Corporation (the "Board of Directors") by its Restated
Certificate of Incorporation (hereinafter referred to as the "Restated
Certificate of Incorporation"), and pursuant to the provisions of Section 151
of the General Corporation Law of the State of Delaware, said Board of
Directors, at a meeting duly called and held on March 28, 1997, duly approved
and adopted the following resolution (the "Resolution"):

   RESOLVED that, pursuant to the authority vested in the Board of Directors by
  its Certificate of Incorporation, the Board of Directors does hereby create,
  authorize and provide for the issuance of 7 1/4% Junior Convertible Preferred
  Stock Due 2007, par value $.01 per share, with a stated value initially of
  $100 per share, consisting of up to 1,400,000 shares having the designation,
  preferences, relative, participating, optional and other special rights and
  the qualifications, limitations and restrictions thereof that are set forth
  in the Restated Certificate of Incorporation and in this Resolution as
  follows:

   (a)  Designation.  There is hereby created out of the authorized and
unissued shares of Preferred Stock of the Company a series of Preferred Stock
designated as the "7 1/4% Junior Convertible Preferred Stock Due 2007" (the
"Convertible Preferred Stock").  The number of shares constituting the
Convertible Preferred Stock shall be 1,400,000.  The liquidation preference of
the Convertible Preferred Stock shall be $100 per share (the "Liquidation
Preference").
<PAGE>   2


   (b)  Rank.  The Convertible Preferred Stock will, with respect to dividend
rights and rights on liquidation, winding-up and dissolution, rank (i) senior
to all classes of common stock and to each other class of Capital Stock or
series of Preferred Stock established hereafter by the Board of Directors of
the Company, the terms of which do not expressly provide that it ranks senior
to, or on a parity with, the Convertible Preferred Stock as to dividend rights
and rights on liquidation, winding-up and dissolution of the Company
(collectively referred to, together with all classes of common stock of the
Company, as "Junior Stock"); (ii) on a parity with each other class of Capital
Stock or series of Preferred Stock established hereafter by the Board of
Directors of the Company, the terms of which expressly provide that such class
or series will rank on a parity with the Convertible Preferred Stock as to
dividend rights and rights on liquidation, winding-up and dissolution
(collectively referred to as "Parity Stock"); and (iii) junior to each share of
Series 3 Preferred Stock now or hereafter outstanding and junior to each class
of Capital Stock or series of Preferred Stock established hereafter by the
Board of Directors of the Company, the terms of which hereafter established
classes or series expressly provide that such class or series will rank senior
to the Convertible Preferred Stock as to dividend rights or rights on
liquidation, winding-up and dissolution of the Company (collectively referred
to as "Senior Stock").  The Company may not authorize, create or increase the
authorized amount of any class or series of Senior Stock without the approval
of the holders of at least two-thirds of the shares of Convertible Preferred
Stock then outstanding, voting or consenting, as the case may be, as one class.
All claims of the holders of the Convertible Preferred Stock, including claims
with respect to dividend payments, redemption payments, mandatory repurchase
payments or rights upon liquidation, winding-up or dissolution, shall rank
junior to the claims of the holders of any debt of the Company and all other
creditors of the Company.

   (c)  Dividends.  (i)  Holders of the outstanding shares of Convertible
Preferred Stock will be entitled to receive, when, as and if declared by the
Board of Directors of the Company, out of funds legally available therefor,
dividends on each share of the Convertible Preferred Stock at a rate per annum
equal to 7 1/4% of the Liquidation


                                       2
<PAGE>   3
Preference of such share payable quarterly (each such quarterly period being
herein called a "Dividend Period").  In addition to the dividends described in
the preceding sentence, holders of outstanding shares of Convertible Preferred
Stock which are Transfer Restricted Securities will be entitled to additional
dividends (the "Additional Dividends"), when, as and if declared by the Board
of Directors of the Company, out of funds legally available therefor, with
respect to the shares of Convertible Preferred Stock, which Additional
Dividends shall accrue as follows if any of the following events occur (each
such event in clauses (A) and (B) below being herein called a "Registration
Default"):  (A) if by August 31, 1997, the Shelf Registration Statement has not
been declared effective by the Commission; or (B) if after the Shelf
Registration Statement is declared effective (1) the Shelf Registration
Statement thereafter ceases to be effective; or (2) the Shelf Registration
Statement or the related prospectus ceases to be usable (in each case except as
permitted below) in connection with resales of Transfer Restricted Securities
in accordance with and during the periods specified herein because either (I)
any event occurs as a result of which the related prospectus forming part of
such Shelf Registration Statement would include any untrue statement of a
material fact or omit to state any material fact necessary to make the
statements therein in the light of the circumstances under which they were made
not misleading, or (II) it shall be necessary to amend such Shelf Registration
Statement or supplement the related prospectus, to comply with the Securities
Act or the Exchange Act or the respective rules thereunder.

   Additional Dividends shall accrue on the shares of Convertible Preferred
Stock which are Transfer Restricted Securities from and including the date on
which any such Registration Default shall occur, to but excluding the date on
which all such Registration Defaults have been cured, at a rate of 7 3/4% per
annum.

   A Registration Default referred to in clause (B) of paragraph (c)(i) shall
be deemed not to have occurred and be continuing in relation to the Shelf
Registration Statement or the related prospectus if (i) such Registration
Default has occurred solely as a result of (x) the filing of a post-effective
amendment to the Shelf Registration Statement to incorporate annual audited
financial information with respect to the Company where such post-effective
amendment is not yet effective and needs to be


                                       3
<PAGE>   4
declared effective to permit Holders to use the related prospectus or (y) other
material events with respect to the Company that would need to be described in
the Shelf Registration Statement or the related prospectus and (ii) in the case
of clause (y), the Company proceeds promptly and in good faith to amend or
supplement the Shelf Registration Statement and related prospectus to describe
such events unless the Company has determined in good faith that there are
material legal or commercial impediments in doing so; provided, however, that
in any case if such Registration Default occurs for a continuous period in
excess of 45 days, Additional Dividends shall be payable in accordance with the
immediately preceding paragraphs of this paragraph (c)(i) from the day such
Registration Default initially occurs until such Registration Default is cured.

   Any amounts of Additional Dividends due pursuant to clauses (A) or (B) of
this paragraph (c)(i) or pursuant to the proviso contained in the preceding
sentence will be payable on the regular dividend payment dates with respect to
the Convertible Preferred Stock and on the same terms and conditions and
subject to the same limitations as pertain at such time for the payment of
regular dividends.  The amount of Additional Dividends will be determined by
multiplying the applicable Additional Dividends rate by the aggregate
liquidation preference of the outstanding shares of Convertible Preferred
Stock, multiplied by a fraction, the numerator of which is the number of days
such Additional Dividend rate was applicable during such period (determined on
the basis of a 360-day year comprised of twelve 30-day months), and the
denominator of which is 360.

   All dividends on the Convertible Preferred Stock, including Additional
Dividends, to the extent accrued, shall be cumulative, whether or not earned or
declared, on a daily basis from the Issue Date or, in the case of additional
shares of Convertible Preferred Stock issued in payment of a dividend, from the
date of issuance of such additional shares of Convertible Preferred Stock, and
shall be payable quarterly in arrears on March 31, June 30, September 30 and
December 31 of each year (each a "Dividend Payment Date"), commencing on June
30, 1997 to holders of record on the March 15, June 15, September 15 and
December 15 immediately preceding the relevant Dividend Payment Date.  Any
dividend on the Convertible Preferred Stock payable pursuant to this paragraph
(c)(i) on or prior to March 31, 1999 shall be, at the option of the Company,
payable (1) in cash or (2) through the issuance of a number of additional
shares


                                       4
<PAGE>   5
(rounded to the nearest whole share) of Convertible Preferred Stock (the
"Additional Shares") equal to the dividend amount divided by the Liquidation
Preference of such Additional Shares.  With respect to dividends accrued after
March 31, 1999, all dividends shall be payable in cash; provided, however, that
to the extent and for so long as the Company is prohibited by the terms of any
of its indebtedness then outstanding or by the terms of the Series 3 Preferred
Stock of the Company or any agreement or instrument to which the Company is
then subject, from paying cash dividends on the Convertible Preferred Stock,
such dividends will accrue on each share at the rate per annum equal to 8 3/4%
of the Liquidation Preference per share (instead of the 7 1/4% rate set forth
in the first paragraph of this paragraph (c)(i)) (together with any Additional
Dividends then payable, which for purposes of this paragraph shall be payable
at a rate of 0.50% over and above the 8 3/4% rate) payable through the issuance
of a number of Additional Shares (rounded to the nearest whole share) equal to
the dividend amount on such share divided by the Liquidation Preference of such
Additional Shares on the relevant Dividend Payment Date.  Except as provided
herein, accrued and unpaid dividends, if any, will not bear interest or bear
dividends thereon.

   (ii)  All dividends paid with respect to shares of the Convertible Preferred
Stock pursuant to paragraph (c)(i) shall be paid pro rata to the holders
entitled thereto.

   (iii)  No full dividends may be declared or paid or set apart for the
payment of dividends by the Company on any Parity Stock for any period unless
full cumulative dividends in respect of each Dividend Period ending on or
before such period shall have been or contemporaneously are declared and paid
(or are deemed declared and paid) in full or declared and, if payable in cash,
a sum in cash sufficient for such payment set apart for such payment on the
Convertible Preferred Stock.  If full dividends are not so paid, the
Convertible Preferred Stock will share dividends pro rata with the Parity
Stock.

   (iv)  The Company will not (A) declare, pay or set apart funds for the
payment of any dividend or other distribution with respect to any Junior Stock
or (B) redeem, purchase or otherwise acquire for consideration any Junior Stock
through a sinking fund or otherwise, unless (1) all accrued and unpaid
dividends with respect to the Convertible Preferred Stock and any Parity Stock
at the time such


                                       5
<PAGE>   6
dividends are payable have been paid or funds have been set apart for payment
of such dividends and (2) sufficient funds have been paid or set apart for the
payment of the dividend for the current dividend period with respect to the
Convertible Preferred Stock and any Parity Stock.  As used herein, the term
"dividend" does not include dividends payable solely in shares of Junior Stock
on Junior Stock or in options, warrants or rights to holders of Junior Stock to
subscribe or purchase any Junior Stock.

   (v)  Dividends on account of arrears for any past Dividend Period and
dividends in connection with any optional redemption may be declared and paid
at any time, without reference to any regular Dividend Payment Date, to holders
of record on such date, not more than 45 days prior to the payment thereof, as
may be fixed by the Board of Directors of the Company.

   (vi)  Dividends payable on the Convertible Preferred Stock for any period
other than a Dividend Period shall be computed on the basis of a 360-day
consisting year of twelve 30-day months and the actual number of days elapsed
in the period for which payable.  Dividends payable on the Convertible
Preferred Stock for a full Dividend Period will be computed by dividing the per
annum dividend rate by four.

   (vii)  Certificates of Common Stock relating to Convertible Preferred Stock
surrendered for conversion by a registered Holder during the period from the
close of business on any regular record date next preceding any Dividend
Payment Date to the opening of business on such Dividend Payment Date (except
Convertible Preferred Shares called for redemption on a Redemption Date within
such period) must be accompanied by payment in cash of an amount equal to the
accrued but unpaid dividends thereon which such registered Holder is to receive
on such Dividend Payment Date with respect to the Convertible Preferred Stock
so surrendered.

   (d)  Liquidation Preference.  (i)  Upon any voluntary or involuntary
liquidation, dissolution or winding-up of the Company, holders of Convertible
Preferred Stock will be entitled to be paid, out of the assets of the Company
available for distribution to its stockholders, the Liquidation Preference of
the outstanding shares of Convertible Preferred Stock, plus, without
duplication, an amount in cash equal to all accumulated and unpaid dividends


                                       6
<PAGE>   7
(whether or not earned or declared and including Additional Dividends, if any,)
thereon to the date fixed for liquidation, dissolution or winding-up (including
an amount equal to a prorated dividend for the period from the last Dividend
Payment Date to the date fixed for liquidation, dissolution or winding-up that
would have been payable had the Convertible Preferred Stock been the subject of
an Optional Redemption on such date) before any distribution is made on any
Junior Stock.  If, upon any voluntary or involuntary liquidation, dissolution
or winding up of the Company, the amounts payable with respect to the
Convertible Preferred Stock and all Parity Stock are not paid in full, the
Convertible Preferred Stock and the Parity Stock will share equally and ratably
(in proportion to the respective amounts that would be payable on such shares
of Convertible Preferred Stock and the Parity Stock, respectively, if all
amounts payable thereon had been paid in full) in any distribution of assets of
the Company to which each is entitled.  After payment of the full amount of the
Liquidation Preference of the outstanding shares of Convertible Preferred Stock
(and, if applicable, an amount equal to a prorated dividend), the holders of
shares of Convertible Preferred Stock will not be entitled to any further
participation in any distribution of assets of the Company.

   (ii)  For the purposes of this paragraph (d), neither the sale, conveyance,
exchange or transfer (for cash, shares of stock, securities or other
consideration) of all or substantially all of the property or assets of the
Company nor the consolidation or merger of the Company with or into one or more
other entities shall be deemed to be a liquidation, dissolution or winding-up
of the Company.

   (e)  Redemption.  (i)  Optional Redemption.  (A)  The Convertible Preferred
Stock shall not be redeemable prior to April 3, 2000.  On or after April 3,
2000, each share of the Convertible Preferred Stock may be redeemed (subject to
the legal availability of funds therefor) at any time, in whole or in part, at
the option of the Company, at the redemption prices (expressed as a percentage
of the Liquidation Preference of such share) set forth below, plus, without
duplication, an amount in cash equal to all accrued and unpaid Liquidated
Damages and all accrued and unpaid dividends to the date fixed for redemption
(the "Optional Redemption Date") (including an amount in cash equal to a
prorated dividend for the period from the Dividend Payment Date immediately
prior to the Optional Redemption Date) (the


                                       7
<PAGE>   8
"Optional Redemption Price").  Notwithstanding the foregoing, prior to April 1,
2002, the Company shall only have the option to redeem shares of Convertible
Preferred Stock if, during the period of 30 consecutive Trading Days ending on
the Trading Day immediately preceding the date that the Redemption Notice is
mailed to holders, the Closing Bid Price for the Common Stock exceeded 150% of
the Conversion Price effective on the date of such Redemption Notice for at
least 20 of such Trading Days.  If redeemed during the 12-month period
beginning April 1 of each of the years set forth below (or in the case of the
year 2000, April 3), the Optional Redemption Price per share shall be the
applicable percentage of the Liquidation Preference of such share set forth
below plus, without duplication, in each case, an amount in cash equal to all
accrued and unpaid Liquidated Damages and all accrued and unpaid dividends
(including an amount equal to a prorated dividend from the immediately
preceding Dividend Payment Date to the Optional Redemption Date), if any, to
the Optional Redemption Date:

   (B)  In the event of a redemption of only a portion of the then outstanding
shares of Convertible Preferred Stock, the Company shall effect such redemption
on a pro rata basis, except that the Company may redeem all of the shares held
by holders of fewer than 100 shares (or all of the shares held by holders who
would hold less than 100 shares as a result of such redemption), as may be
determined by the Company.

   (ii)  Mandatory Redemption.  Each share of the Convertible Preferred Stock
(if not earlier redeemed or converted) shall be subject to mandatory redemption
in whole (to the extent of lawfully available funds therefor) on March 31, 2007
(the "Mandatory Redemption Date") at a price equal to 100% of the Liquidation
Preference of such share, plus, without duplication, all accrued and unpaid
Liquidated Damages and accrued and unpaid dividends thereon (including


                                       8
<PAGE>   9
an amount equal to a prorated dividend thereon from the immediately preceding
Dividend Payment Date to the Mandatory Redemption Date), if any, to the
Mandatory Redemption Date (the "Mandatory Redemption Price").

   (iii)  Procedure for Redemption.  (A)  On and after the Optional Redemption
Date or the Mandatory Redemption Date, as the case may be (the "Redemption
Date"), unless the Company defaults in the payment of the applicable redemption
price, dividends will cease to accumulate on shares of Convertible Preferred
Stock called for redemption and all rights of holders of such shares will
terminate except for the right to receive the Optional Redemption Price or the
Mandatory Redemption Price, as the case may be, without interest; provided,
however, that if a notice of redemption shall have been given as provided in
paragraph (iii)(B) and the funds necessary for redemption (including an amount
in respect of all dividends that will accrue to the Redemption Date) shall have
been segregated and irrevocably set apart by the Company, in trust for the
benefit of the holders of the shares called for redemption, then dividends
shall cease to accumulate on the Redemption Date on the shares to be redeemed
and, at the close of business on the day on which such funds are segregated and
set apart, the holders of the shares to be redeemed shall, with respect to the
shares to be redeemed, cease to be stockholders of the Company and shall be
entitled only to receive the Optional Redemption Price or the Mandatory
Redemption Price, as the case may be, for such shares without interest from the
Redemption Date.

   (B)  With respect to a redemption pursuant to paragraph (e)(i) or (e)(ii),
the Company will send a written notice of redemption by first class mail to
each holder of record of shares of Convertible Preferred Stock, not fewer than
15 days nor more than 60 days prior to the Redemption Date at its registered
address (the "Redemption Notice"); provided, however, that no failure to give
such notice nor any deficiency therein shall affect the validity of the
procedure for the redemption of any shares of Convertible Preferred Stock to be
redeemed except as to the holder or holders to whom the Company has failed to
give said notice or except as to the holder or holders whose notice was
defective.  The Redemption Notice shall state:

    (1) whether the redemption is pursuant to paragraph (e)(i) or (e)(ii)
  hereof;


                                       9
<PAGE>   10
     (2) the Optional Redemption Price or the Mandatory Redemption Price, as
  the case may be;

     (3) whether all or less than all the outstanding shares of the Convertible
  Preferred Stock are to be redeemed and the total number of shares of the
  Convertible Preferred Stock being redeemed;

     (4) the Redemption Date;

     (5) that the holder is to surrender to the Company, in the manner, at the
  place or places and at the price designated, his certificate or certificates
  representing the shares of Convertible Preferred Stock to be redeemed; and

     (6) that dividends on the shares of the Convertible Preferred Stock to be
  redeemed shall cease to accumulate on such Redemption Date unless the Company
  defaults in the payment of the Optional Redemption Price or the Mandatory
  Redemption Price, as the case may be.

   (C)  Each holder of Convertible Preferred Stock shall surrender the
certificate or certificates representing such shares of Convertible Preferred
Stock to the Company, duly endorsed (or otherwise in proper form for transfer,
as determined by the Company), in the manner and at the place designated in the
Redemption Notice, and on the Redemption Date the full Optional Redemption
Price or Mandatory Redemption Price, as the case may be, for such shares shall
be payable in cash to the person whose name appears on such certificate or
certificates as the owner thereof, and each surrendered certificate shall be
canceled and retired.  In the event that less than all of the shares
represented by any such certificate are redeemed, a new certificate shall be
issued representing the unredeemed shares.

   (f)  Voting Rights.  (i)  The holders of Convertible Preferred Stock, except
as otherwise required under Delaware law or as set forth in paragraphs (ii) and
(iii) below, shall not be entitled or permitted to vote on any matter required
or permitted to be voted upon by the stockholders of the Company.

   (ii)  (A)  If (1) dividends on the Convertible Preferred Stock are in
arrears and unpaid for six or more Dividend Periods (whether or not
consecutive) (a "Dividend


                                       10
<PAGE>   11
Default"); or (2) the Company fails to redeem the Convertible Preferred Stock on
March 31, 2007, or fails to otherwise discharge any redemption obligation with
respect to the Convertible Preferred Stock, then the number of directors
constituting the Board of Directors of the Company will be increased by two and
the Holders of the then outstanding shares of Convertible Preferred Stock
(together with the holders of Parity Stock upon which like rights have been
conferred and are exercisable), voting separately and as a class, shall have the
right and power to elect such two additional directors.  Each such event
described in clauses (1) or (2) above is a "Voting Rights Triggering Event". A
Voting Rights Triggering Event shall not be deemed to have occurred if at the
time of such event there are less than 200,000 shares of Convertible Preferred
Stock then outstanding.

   (B)  The voting rights set forth in subparagraph (f)(ii)(A) above will
continue until such time as (x) in the case of a Dividend Default, all
dividends in arrears on the Convertible Preferred Stock are paid in full in
cash, (y) in all other cases, any failure, breach or default giving rise to
such Voting Rights Triggering Event is remedied or waived by the Holders of at
least two-thirds of the shares of Convertible Preferred Stock then outstanding
or (z) at any time there are less than 200,000 shares of Convertible Preferred
Stock outstanding, at which time the term of any directors elected pursuant to
the provisions of subparagraph (f)(ii)(A) above shall terminate and the number
of directors constituting the Board of Directors shall be decreased by two
(until the occurrence of any subsequent Voting Rights Triggering Event).  At
any time after voting power to elect directors shall have become vested and be
continuing in the holders of Convertible Preferred Stock (together with the
holders of Parity Stock upon which like rights have been conferred and are
exercisable) pursuant to subparagraph (f)(ii)(A) hereof, or if vacancies shall
exist in the offices of directors elected by such holders, a proper officer of
the Company may, and upon the written request of the holders of record of at
least 25% of the shares of Convertible Preferred Stock then outstanding or the
holders of 25% of the shares of Parity Stock then outstanding upon which like
rights have been confirmed and are exercisable addressed to the secretary of
the Company shall, call a special meeting of the Holders of Convertible
Preferred Stock and the holders of such Parity Stock for the purpose of
electing the directors which such holders are entitled to elect pursuant to the
terms hereof;


                                       11
<PAGE>   12
provided, however, that no such special meeting shall be called if the next
annual meeting of stockholders of the Company is to be held within 60 days
after the voting power to elect directors shall have become vested, in which
case such meeting shall be deemed to have been called for such next annual
meeting.  If such meeting shall not be called by a proper officer of the
Company within 20 days after personal service to the secretary of the Company
at its principal executive offices, then the Holders of record of at least 25%
of the outstanding shares of Convertible Preferred Stock or the holders of 25%
of the shares of Parity Stock upon which like rights have been confirmed and
are exercisable may designate in writing one of their members to call such
meeting at the expense of the Company, and such meeting may be called by the
person so designated upon the notice required for the annual meetings of
stockholders of the Company and shall be held at the place for holding the
annual meetings of stockholders.  Any holder of Convertible Preferred Stock or
such Parity Stock so designated shall have, and the Company shall provide,
access to the lists of holders of Convertible Preferred Stock and the holders
of such Parity Stock to be called pursuant to the provisions hereof.  If no
special meeting of the Holders of Convertible Preferred Stock and the holders
of such Parity Stock is called as provided in this paragraph (f)(ii), then such
meeting shall be deemed to have been called for the next annual meeting of
stockholders of the Company or special meeting of the holders of any other
capital stock of the Company.

   (C)  At any meeting held for the purposes of electing directors at which the
Holders of Convertible Preferred Stock (together with the holders of Parity
Stock upon which like rights have been conferred and are exercisable) shall
have the right, voting together as a separate class, to elect directors as
aforesaid, the presence in person or by proxy of the holders of at least a
majority in voting power of the outstanding shares of Convertible Preferred
Stock (and such Parity Stock) shall be required to constitute a quorum thereof.

   (D)  Any vacancy occurring in the office of a director elected by the
Holders of Convertible Preferred Stock (and such Parity Stock) may be filled by
the remaining director elected by the Holders of Convertible Preferred Stock
(and such Parity Stock) unless and until such vacancy shall be filled by the
Holders of Convertible Preferred Stock (and such Parity Stock).


                                       12
<PAGE>   13
   (iii)  (A)  So long as any shares of the Convertible Preferred Stock are
outstanding, the Company will not authorize, create or increase the authorized
amount of any class or series of Senior Stock without the affirmative vote or
consent of holders of at least two-thirds of the shares of Convertible
Preferred Stock then outstanding, voting or consenting, as the case may be, as
one class, given in person or by proxy, either in writing or by resolution
adopted at an annual or special meeting (except that no such vote or consent
shall be required for the issuance of additional shares of Series 3 Preferred
Stock to be paid as dividends on such Series 3 Preferred Stock pursuant to the
terms of such Series 3 Preferred Stock).

   (B)  So long as any shares of the Convertible Preferred Stock are
outstanding, the Company will not amend this Certificate of Designation so as
to affect adversely the specified rights, preferences, privileges or voting
rights of Holders of shares of Convertible Preferred Stock or to authorize the
issuance of any additional shares of Convertible Preferred Stock (except to
authorize the issuance of additional shares of Convertible Preferred Stock to
be paid as dividends on the Convertible Preferred Stock, for which no consent
shall be necessary) without the affirmative vote or consent of Holders of at
least two-thirds of the issued and outstanding shares of Convertible Preferred
Stock, voting or consenting, as the case may be, as one class, given in person
or by proxy, either in writing or by resolution adopted at an annual or special
meeting.

   (C)  Except as set forth in paragraph (f)(iii)(A) or (B) above, (x) the
creation, authorization or issuance of any shares of any Junior Stock, Parity
Stock or Senior Stock, including the designation of a series of Convertible
Preferred Stock, or (y) the increase or decrease in the amount of authorized
Capital Stock of any class, including Preferred Stock, shall not require the
consent of Holders of Convertible Preferred Stock and shall not be deemed to
affect adversely the rights, preferences, privileges or voting rights of shares
of Convertible Preferred Stock.

   (iv)  In any case in which the Holders of Convertible Preferred Stock shall
be entitled to vote pursuant to this paragraph (f) or pursuant to Delaware law,
each Holder of Convertible Preferred Stock entitled to vote with respect to
such matters shall be entitled to one vote for each share of Convertible
Preferred Stock held.


                                       13
<PAGE>   14
   (v)  Except as required by law, the Holders of the Convertible Preferred
Stock will not be entitled to vote on any merger or consolidation involving the
Company or a sale of all or substantially all the assets of the Company.

   (g)  Conversion.  (i)  At any time after 60 days from the Issue Date, at the
option of the Holder thereof, any share of Convertible Preferred Stock may be
converted at the Liquidation Preference thereof into fully paid and
nonassessable Common Stock (calculated as to each conversion to the nearest
1/100 of a share), at the Conversion Price, determined as hereinafter provided,
in effect at the time of conversion.  Such conversion right shall expire at the
close of business on the Mandatory Redemption Date.  In case a share of
Convertible Preferred Stock is called for optional redemption, such conversion
right in respect of the share of Convertible Preferred Stock so called shall
expire at the close of business on the applicable Optional Redemption Date,
unless the Company defaults in making the payment due upon redemption.

   The price at which Common Stock shall be delivered upon conversion (herein
called the "Conversion Price") shall be initially $23.46 per share of Common
Stock.  The Conversion Price shall be adjusted in certain instances as provided
in paragraph (g)(iv) and paragraph (g)(v).

   (ii)  In order to exercise the conversion privilege, the Holder of any share
of Convertible Preferred Stock to be converted shall surrender the certificate
for such share of Convertible Preferred Stock, duly endorsed or assigned to the
Company or in blank, at the office of the Transfer Agent or at any office or
agency of the Company maintained for that purpose, accompanied by written
notice to the Company in the form of Exhibit B that the Holder elects to
convert such share of Convertible Preferred Stock or, if fewer than all of the
shares of Convertible Preferred Stock represented by a single share certificate
are to be converted, the number of shares represented thereby to be converted.
Except as provided in paragraph (c)(viii), no payment or adjustment shall be
made upon any conversion on account of any dividends accrued on the shares of
Convertible Preferred Stock surrendered for conversion or on account of any
dividends on the Common Stock issued upon conversion.  Such notice shall also
contain the office or the address to which the Company should deliver shares of
Common Stock issuable upon conversion (and any other payments or certificates
related thereto).  Except as


                                       14
<PAGE>   15
provided in paragraph (c)(viii), in no event shall the Company be obligated to
pay any converting Holder any unpaid dividend, whether or not in arrears, on
converted shares or any dividends on the shares of Common Stock issued upon
such conversion.

   Shares of Convertible Preferred Stock shall be deemed to have been converted
immediately prior to the close of business on the day of surrender of such
shares of Convertible Preferred Stock for conversion in accordance with the
foregoing provisions, and at such time the rights of the Holders of such shares
of Convertible Preferred Stock as Holders shall cease, and the person or
persons entitled to receive the Common Stock issuable upon conversion shall be
treated for all purposes as the record holder or holders of such Common Stock
at such time.  As promptly as practicable on or after the conversion date, the
Company shall issue and shall deliver to such office or agency as the
converting Holder shall have designated in its written notice to the Company a
certificate or certificates for the number of full Common Stock issuable upon
conversion, together with payment in lieu of any fraction of a share, as
provided in paragraph (g)(iii) hereof.

   In the case of any conversion of fewer than all the shares of Convertible
Preferred Stock evidenced by a certificate, upon such conversion the Company
shall execute and the Transfer Agent shall authenticate and deliver to the
Holder thereof (at the address designated by such Holder), at the expense of
the Company, a new certificate or certificates representing the number of
unconverted shares of Convertible Preferred Stock.

   (iii)  No fractional Common Stock shall be issued upon the conversion of a
share of Convertible Preferred Stock.  If more than one share of Convertible
Preferred Stock shall be surrendered for conversion at one time by the same
holder, the number of full shares of Common Stock which shall be issuable upon
conversion thereof shall be computed on the basis of the aggregate shares of
Convertible Preferred Stock so surrendered.  Instead of any fractional share of
Common Stock which would otherwise be issuable upon conversion of any share of
Convertible Preferred Stock, the Company shall pay a cash adjustment in respect
of such fraction in an amount equal to the same fraction of the closing price
(as defined in paragraph (g)(iv)(7)) per share of Common Stock at the close of
business on the Business Day prior to the day of conversion.


                                       15
<PAGE>   16
   (iv)  The Conversion Price shall be adjusted from time to time by the
Company as follows:

    (1)  If the Company shall hereafter pay a dividend or make a distribution in
  Common Stock to all holders of any outstanding class or series of Common
  Stock of the Company, the Conversion Price in effect at the opening of
  business on the date following the date fixed for the determination of
  shareholders entitled to receive such dividend or other distribution shall be
  reduced by multiplying such Conversion Price by a fraction of which the
  numerator shall be the number of shares of Common Stock outstanding at the
  close of business on the Record Date (as defined in paragraph (g)(iv)(7))
  fixed for such determination and the denominator shall be the sum of such
  number of outstanding shares and the total number of shares constituting such
  dividend or other distribution, such reduction to become effective
  immediately after the opening of business on the day following the Record
  Date.  If any dividend or distribution of the type described in this
  paragraph (g)(iv)(i) is declared but not so paid or made, the Conversion
  Price shall again be adjusted to the Conversion Price which would then be in
  effect if such dividend or distribution had not been declared.

    (2)  If the Company shall offer or issue rights or warrants to all holders
  of its outstanding Common Stock entitling them to subscribe for or purchase
  Common Stock at a price per share less than the Current Market Price (as
  defined in paragraph (g)(iv)(7)) on the Record Date fixed for the
  determination of shareholders entitled to receive such rights or warrants,
  the Conversion Price shall be adjusted so that the same shall equal the price
  determined by multiplying the Conversion Price in effect at the opening of
  business on the date after such Record Date by a fraction of which the
  numerator shall be the number of shares of Common Stock outstanding at the
  close of business on the Record Date plus the number of shares of Common
  Stock which the aggregate offering price of the total number of shares of
  Common Stock subject to such rights or warrants would purchase at such
  Current Market Price and of which the denominator shall be the number of
  shares of Common Stock outstanding at the close of business on the Record
  Date plus the total number of additional shares of Common Stock subject to
  such


                                       16
<PAGE>   17
  rights or warrants for subscription or purchase.  Such adjustment shall
  become effective immediately after the opening of business on the day
  following the Record Date fixed for determination of shareholders entitled to
  purchase or receive such rights or warrants.  To the extent that shares of
  Common Stock are not delivered pursuant to such rights or warrants, upon the
  expiration or termination of such rights or warrants the Conversion Price
  shall again be adjusted to be the Conversion Price which would then be in
  effect had the adjustments made upon the issuance of such rights or warrants
  been made on the basis of delivery of only the number of shares of Common
  Stock actually delivered.  If such rights or warrants are not so issued, the
  Conversion Price shall again be adjusted to be the Conversion Price which
  would then be in effect if such date fixed for the determination of
  shareholders entitled to receive such rights or warrants had not been fixed.
  In determining whether any rights or warrants entitle the holders to
  subscribe for or purchase Common Stock at less than such Current Market
  Price, and in determining the aggregate offering price of such shares of
  Common Stock, there shall be taken into account any consideration received
  for such rights or warrants, with the value of such consideration, if other
  than cash, to be determined by the Board of Directors.

    (3)  If the outstanding shares of Common Stock shall be subdivided into a
  greater number of shares of Common Stock, the Conversion Price in effect at
  the opening of business on the day following the day upon which such
  subdivision becomes effective shall be proportionately reduced, and,
  conversely, if the outstanding shares of Common Stock shall be combined into
  a smaller number of shares of Common Stock, the Conversion Price in effect at
  the opening of business on the day following the day upon which such
  combination becomes effective shall be proportionately increased, such
  reduction or increase, as the case may be, to become effective immediately
  after the opening of business on the day following the day upon which such
  subdivision or combination becomes effective.

    (4)  If the Company shall, by dividend or otherwise, distribute to all
  holders of its shares of Common Stock shares of any class of capital stock of
  the Company (other than any dividends or distributions


                                       17
<PAGE>   18
  to which paragraph (g)(iv)(1) applies) or evidences of its indebtedness, cash
  or other assets (including securities, but excluding any rights or warrants
  of a type referred to in paragraph (g)(iv)(2) and excluding dividends and
  distributions paid exclusively in cash and excluding any capital stock,
  evidences of indebtedness, cash or assets distributed upon a merger or
  consolidation to which paragraph (g)(v) applies) (the foregoing hereinafter
  in this paragraph (g)(iv)(4) called the "Distributed Securities"), then, in
  each such case, the Conversion Price shall be reduced so that the same shall
  be equal to the price determined by multiplying the Conversion Price in
  effect immediately prior to the close of business on the Record Date (as
  defined in paragraph (g)(iv)(7)) with respect to such distribution by a
  fraction of which the numerator shall be the Current Market Price (determined
  as provided in paragraph (g)(iv)(7)) of the Common Stock on such date less
  the fair market value (as determined by the Board of Directors, whose
  determination shall be conclusive and described in a resolution of the Board
  of Directors) on such date of the portion of the Distributed Securities so
  distributed applicable to one share of Common Stock and the denominator shall
  be such Current Market Price, such reduction to become effective immediately
  prior to the opening of business on the day following the Record Date;
  provided, however, that, in the event the then fair market value (as so
  determined) of the portion of the Distributed Securities so distributed
  applicable to one share of Common Stock is equal to or greater than the
  Current Market Price on the Record Date, in lieu of the foregoing adjustment,
  adequate provision shall be made so that each holder of Convertible Preferred
  Stock shall have the right to receive upon conversion of a share of
  Convertible Preferred Stock (or any portion thereof) the amount of
  Distributed Securities such holder would have received had such holder
  converted such share of Convertible Preferred Stock (or portion thereof)
  immediately prior to such Record Date.  If such dividend or distribution is
  not so paid or made, the Conversion Price shall again be adjusted to be the
  Conversion Price which would then be in effect if such dividend or
  distribution had not been declared.  If the Board of Directors determines the
  fair market value of any distribution for purposes of this paragraph
  (g)(iv)(4) by reference to the actual or when issued trading market for any
  securities comprising all


                                       18
<PAGE>   19
  or part of such distribution, it must in doing so consider the prices in such
  market over the same period used in computing the Current Market Price
  pursuant to paragraph (g)(iv)(7) to the extent possible.

  Rights or warrants distributed by the Company to all holders of Common Stock
  entitling the holders thereof to subscribe for or purchase shares of the
  Company's capital stock (either initially or under certain circumstances),
  which rights or warrants, until the occurrence of a specified event or events
  ("Dilution Trigger Event"): (i) are deemed to be transferred with such
  Common Stock; (ii) are not exercisable; and (iii) are also issued in respect
  of future issuances of Common Stock, shall be deemed not to have been
  distributed for purposes of this paragraph (g)(iv)(4) (and no adjustment to
  the Conversion Price under this paragraph (g)(iv)(4) shall be required) until
  the occurrence of the earliest Dilution Trigger Event, whereupon such rights
  and warrants shall be deemed to have been distributed and an appropriate
  adjustment to the Conversion Price under this paragraph (g)(iv)(4) shall be
  made.  If any such rights or warrants, including any such existing rights or
  warrants distributed prior to the date hereof, are subject to subsequent
  events, upon the occurrence of each of which such rights or warrants shall
  become exercisable to purchase different securities, evidences of
  indebtedness or other assets, then the occurrence of each such event shall be
  deemed to be such date of issuance and record date with respect to new rights
  or warrants (and a termination or expiration of the existing rights or
  warrants without exercise by the holder thereof).  In addition, in the event
  of any distribution (or deemed distribution) of rights or warrants, or any
  Dilution Trigger Event with respect thereto, that was counted for purposes of
  calculating a distribution amount for which an adjustment to the Conversion
  Price under this paragraph (g)(iv)(4) was made, (1) in the case of any such
  rights or warrants which shall all have been redeemed or repurchased without
  exercise by any holders thereof, the Conversion Price shall be readjusted
  upon such final redemption or repurchase to give effect to such distribution
  or Dilution Trigger Event, as the case may be, as though it were a cash
  distribution, equal to the per share redemption or repurchase price received
  by a holder or holders of Common Stock with respect to such rights or


                                       19
<PAGE>   20
  warrants (assuming such holder had retained such rights or warrants), made to
  all holders of Common Stock as of the date of such redemption or repurchase,
  and (2) in the case of such rights or warrants which shall have expired or
  been terminated without exercise by any holders thereof, the Conversion Price
  shall be readjusted as if such rights and warrants had not been issued.

  Notwithstanding any other provision of this paragraph (g)(iv)(4) to the
  contrary, capital stock, rights, warrants, evidences of indebtedness, other
  securities, cash or other assets (including, without limitation, any rights
  distributed pursuant to any shareholder rights plan) shall be deemed not to
  have been distributed for purposes of this paragraph (g)(iv)(4) if the
  Company makes proper provision so that each holder of shares of Convertible
  Preferred Stock who converts a share of Convertible Preferred Stock (or any
  portion thereof) after the date fixed for determination of shareholders
  entitled to receive such distribution shall be entitled to receive upon such
  conversion, in addition to the Common Stock issuable upon such conversion,
  the amount and kind of such distributions that such holder would have been
  entitled to receive if such holder had, immediately prior to such
  determination date, converted such share of Convertible Preferred Stock into
  Common Stock.

  For purposes of this paragraph (g)(iv)(4) and paragraphs (g)(iv)(1) and (2),
  any dividend or distribution to which this paragraph (g)(iv)(4) is
  applicable that also includes Common Stock, or rights or warrants to
  subscribe for or purchase Common Stock to which paragraph (g)(iv)(2) applies
  (or both), shall be deemed instead to be (1) a dividend or distribution of
  the evidences of indebtedness, cash, assets, shares of capital stock, rights
  or warrants other than (A) such shares of Common Stock or (B) rights or
  warrants to which paragraph (g)(iv)(2) applies (and any Conversion Price
  reduction required by this paragraph (g)(iv)(4) with respect to such dividend
  or distribution shall then be made) immediately followed by (2) a dividend or
  distribution of such Common Stock or such rights or warrants (and any further
  Conversion Price reduction required by paragraph (g)(iv)(1) and (2) with
  respect to such dividend or distribution shall then be made), except that (1)
  the Record Date of such


                                       20
<PAGE>   21
  dividend or distribution shall be substituted as "the Record Date fixed for
  the determination of stockholders entitled to receive such dividend or other
  distribution", "Record Date fixed for such determination" and "Record Date"
  within the meaning of paragraph (g)(iv)(1) and as "the Record Date fixed for
  the determination of shareholders entitled to receive such rights or
  warrants", "the date fixed for the determination of the shareholders entitled
  to receive such rights or warrants" and "such Record Date" within the meaning
  of paragraph (g)(iv)(2), and (2) any share of Common Stock included in such
  dividend or distribution shall not be deemed "outstanding at the close of
  business on the date fixed for such determination" within the meaning of
  paragraph (g)(iv)(1).

    (5)  If the Company shall, by dividend or otherwise, distribute to all
  holders of its Common Stock cash (excluding any cash that is distributed upon
  a merger or consolidation to which paragraph (g)(v) applies or as part of a
  distribution referred to in paragraph (g)(iv)) in an aggregate amount that,
  combined together with (1) the aggregate amount of any other such
  distributions to all holders of its Common Stock made exclusively in cash
  within the 12 months preceding the date of payment of such distribution, and
  in respect of which no adjustment pursuant to this paragraph (g)(iv)(5) has
  been made, and (2) the aggregate of any cash plus the fair market value (as
  determined by the Board of Directors, whose determination shall be conclusive
  and described in a resolution of the Board of Directors) of consideration
  payable in respect of any tender offer by the Company or a Subsidiary of the
  Company for all or any portion of the Common Stock concluded within the 12
  months preceding the date of payment of such distribution, and in respect of
  which no adjustment pursuant to paragraph (g)(iv)(4) has been made, exceeds
  12.5% of the product of the Current Market Price (determined as provided in
  paragraph (g)(iv)(7)) on the Record Date with respect to such distribution
  times the number of shares of Common Stock outstanding on such date, then,
  and in each such case, immediately after the close of business on such date,
  the Conversion Price shall be reduced so that the same shall equal the price
  determined by multiplying the Conversion Price in effect immediately prior to
  the close of business on


                                       21
<PAGE>   22
  such Record Date by a fraction (i) the numerator of which shall be equal to
  the Current Market Price on the Record Date less an amount equal to the
  quotient of (x) the excess of such combined amount over such 12.5% amount
  divided by (y) the number of shares of Common Stock outstanding on the Record
  Date and (ii) the denominator of which shall be equal to the Current Market
  Price on such Record Date; provided, however, that, if the portion of the
  cash so distributed applicable to one share of Common Stock is equal to or
  greater than the Current Market Price of the Common Stock on the Record Date,
  in lieu of the foregoing adjustment, adequate provision shall be made so that
  each holder of Convertible Preferred Stock shall have the right to receive
  upon conversion of a share of Convertible Preferred Stock (or any portion
  thereof) the amount of cash such holder would have received had such holder
  converted such share of Convertible Preferred Stock (or portion thereof)
  immediately prior to such Record Date.  If such dividend or distribution is
  not so paid or made, the Conversion Price shall again be adjusted to be the
  Conversion Price which would then be in effect if such dividend or
  distribution had not been declared.

    (6)  If a tender or exchange offer made by the Company or any of its
  Subsidiaries for all or any portion of the Common Stock expires and such
  tender or exchange offer (as amended upon the expiration thereof) requires
  the payment to shareholders (based on the acceptance (up to any maximum
  specified in the terms of the tender offer) of Purchased Shares (as defined
  below)) of an aggregate consideration having a fair market value (as
  determined by the Board of Directors, whose determination shall be conclusive
  and described in a resolution of the Board of Directors) that, combined
  together with (1) the aggregate of the cash plus the fair market value (as
  determined by the Board of Directors, whose determination shall be conclusive
  and described in a resolution of the Board of Directors), as of the
  expiration of such tender offer, of consideration payable in respect of any
  other tender offers, by the Company or any of its Subsidiaries for all or any
  portion of the Common Stock expiring within the 12 months preceding the
  expiration of such tender offer and in respect of which no adjustment
  pursuant to this paragraph (g)(iv)(6) has been made and (2) the aggregate
  amount of any distributions to all holders of


                                       22
<PAGE>   23
  the Common Stock made exclusively in cash within 12 months preceding the
  expiration of such tender offer and in respect of which no adjustment
  pursuant to paragraph (g)(iv)(5) has been made, exceeds 12.5% of the product
  of the Current Market Price (determined as provided in paragraph (g)(iv)(7))
  as of the last time (the "Expiration Time") tenders could have been made
  pursuant to such tender offer (as it may be amended) times the number of
  shares of Common Stock outstanding (including any tendered shares) at the
  Expiration Time, then, and in each such case, immediately prior to the
  opening of business on the day after the date of the Expiration Time, the
  Conversion Price shall be adjusted so that the same shall equal the price
  determined by multiplying the Conversion Price in effect immediately prior to
  the close of business on the date of the Expiration Time by a fraction of
  which the numerator shall be the number of shares of Common Stock outstanding
  (including any tendered shares) at the Expiration Time multiplied by the
  Current Market Price of the Common Stock on the Trading Day next succeeding
  the Expiration Time and the denominator shall be the sum of (x) the fair
  market value (determined as aforesaid) of the aggregate consideration payable
  to shareholders based on the acceptance (up to any maximum specified in the
  terms of the tender offer) of all shares validly tendered and not withdrawn
  as of the Expiration Time (the shares deemed so accepted, up to any such
  maximum, being referred to as the "Purchased Shares") and (y) the product of
  the number of shares of Common Stock outstanding (less any Purchased Shares)
  at the Expiration Time and the Current Market Price of the Common Stock on
  the Trading Day next succeeding the Expiration Time, such reduction (if any)
  to become effective immediately prior to the opening of business on the day
  following the Expiration Time.  If the Company is obligated to purchase
  shares pursuant to any such tender offer, but the Company is permanently
  prevented by applicable law from effecting any such purchases or all such
  purchases are rescinded, the Conversion Price shall again be adjusted to be
  the Conversion Price which would then be in effect if such tender offer had
  not been made.  If the application of this paragraph (g)(iv)(6) to any tender
  offer would result in an increase in the Conversion Price, no adjustment
  shall be made for such tender offer under this paragraph (g)(iv)(6).


                                       23
<PAGE>   24
    (7)  For purposes of this paragraph (g)(iv), the following terms shall have
  the meaning indicated:

  "closing price" with respect to any securities on any day means the closing
  price on such day or, if no such sale takes place on such day, the average of
  the reported high and low prices on such day, in each case on The Nasdaq
  National Market or the New York Stock Exchange, as applicable, or, if such
  security is not listed or admitted to trading on such national market or
  exchange, on the principal national securities exchange or quotation system
  on which such security is quoted or listed or admitted to trading, or, if not
  quoted or listed or admitted to trading on any national securities exchange
  or quotation system, the average of the high and low prices of such security
  on the over-the-counter market on the day in question as reported by the
  National Quotation Bureau Incorporated or a similar generally accepted
  reporting service, or, if not so available, in such manner as furnished by
  any New York Stock Exchange member firm selected from time to time by the
  Board of Directors for that purpose, or a price determined in good faith by
  the Board of Directors, whose determination shall be conclusive and described
  in a resolution of the Board of Directors.

  "Current Market Price" means the average of the daily closing prices per
  share of Common Stock for the 10 consecutive trading days immediately prior
  to the date in question; provided, however, that (A) if the "ex" date (as
  hereinafter defined) for any event (other than the issuance or distribution
  requiring such computation) that requires an adjustment to the Conversion
  Price pursuant to paragraphs (g)(iv)(1), (2), (3), (4), (5) or (6) occurs
  during such 10 consecutive trading days, the closing price for each trading
  day prior to the "ex" date for such other event shall be adjusted by
  multiplying such closing price by the same fraction by which the Conversion
  Price is so required to be adjusted as a result of such other event, (B) if
  the "ex" date for any event (other than the issuance or distribution
  requiring such computation) that requires an adjustment to the Conversion
  Price pursuant to paragraphs (g)(iv)(1), (2), (3), (4), (5) or (6) occurs on
  or after the "ex" date for the issuance or distribution requiring such
  computation and prior to the day in question, the closing price for each
  trading day on and after the


                                       24
<PAGE>   25
  "ex" date for such other event shall be adjusted by multiplying such closing
  price by the reciprocal of the fraction by which the Conversion Price is so
  required to be adjusted as a result of such other event and (C) if the "ex"
  date for the issuance or distribution requiring such computation is prior to
  the day in question, after taking into account any adjustment required
  pursuant to clause (A) or (B) of this proviso, the closing price for each
  trading day on or after such "ex" date shall be adjusted by adding thereto
  the amount of any cash and the fair market value (as determined by the Board
  of Directors in a manner consistent with any determination of such value for
  purposes of paragraphs (g)(iv)(4) or (5), whose determination shall be
  conclusive and described in a resolution of the Board of Directors) of the
  evidence of indebtedness, shares of capital stock or assets being distributed
  applicable to one Common Stock as of the close of business on the day before
  such "ex" date.  For purposes of any computation under paragraph (g)(vi), the
  Current Market Price on any date shall be deemed to be the average of the
  daily closing prices per share of Common Stock for such day and the next two
  succeeding trading days; provided, however, that, if the "ex" date for any
  event (other than the tender offer requiring such computation) that requires
  an adjustment to the Conversion Price pursuant to paragraph (g)(iv)(1), (2),
  (3), (4), (5) or (6) occurs on or after the Expiration Time for the tender or
  exchange offer requiring such computation and prior to the day in question,
  the closing price for each trading day on and after the "ex" date for such
  other event shall be adjusted by multiplying such closing price by the
  reciprocal of the fraction by which the Conversion Price is so required to be
  adjusted as a result of such other event.  For purposes of this paragraph,
  the term "ex" date (I) when used with respect to any issuance or
  distribution, means the first date on which the Common Stock trades regular
  way on the relevant exchange or in the relevant market from which the closing
  price was obtained without the right to receive such issuance or
  distribution, (II) when used with respect to any subdivision or combination
  of Common Stock, means the first date on which the Common Stock trades
  regular way on such exchange or in such market after the time at which such
  subdivision or combination becomes effective and (III) when used with respect
  to any tender or exchange offer means the first date on which the Common


                                       25
<PAGE>   26
  Stock trades regular way on such exchange or in such market after the
  Expiration Time of such offer.  Notwithstanding the foregoing, whenever
  successive adjustments to the Conversion Price are called for pursuant to this
  paragraph (g)(iv), such adjustments shall be made to the Current Market Price
  as may be necessary or appropriate to effectuate the intent of this paragraph
  (g)(iv) and to avoid unjust or inequitable results, as determined in good
  faith by the Board of Directors.

  "fair market value" shall mean the amount which a willing buyer would pay a
  willing seller in an arm's-length transaction.

  "Record Date" shall mean, with respect to any dividend, distribution or other
  transaction or event in which the holders of Common Stock have the right to
  receive any cash, securities or other property or in which the Common Stock
  (or other applicable security) is exchanged for or converted into any
  combination of cash, securities or other property, the date fixed for
  determination of shareholders entitled to receive such cash, securities or
  other property (whether such date is fixed by the Board of Directors or by
  statute, contract or otherwise).

    (8)  No adjustment in the Conversion Price shall be required unless such
  adjustment would require an increase or decrease of at least 1% in such
  price; provided, however, that any adjustments which by reason of this
  paragraph (g)(iv)(8) are not required to be made shall be carried forward and
  taken into account in any subsequent adjustment.  All calculations under this
  paragraph (g)(iv)(8) shall be made by the Company and shall be made to the
  nearest cent or to the nearest one-hundredth of a share, as the case may be.
  No adjustment need be made for a change in the par value or no par value of
  the Common Stock.

    (9)  Whenever the Conversion Price is adjusted as herein provided, the
  Company shall promptly file with the Transfer Agent an Officers' Certificate
  setting forth the Conversion Price after such adjustment and setting forth a
  brief statement of the facts requiring such adjustment.  Promptly after
  delivery of such certificate, the Company shall prepare a notice of such
  adjustment of the Conversion Price setting forth the


                                       26
<PAGE>   27
  adjusted Conversion Price and the date on which each adjustment becomes
  effective and shall mail such notice of such adjustment of the Conversion
  Price to each holder of Convertible Preferred Stock at such holder's last
  address appearing on the register of holders maintained for that purpose
  within 20 days of the effective date of such adjustment.  Failure to deliver
  such notice shall not affect the legality or validity of any such adjustment.

    (10)  In any case in which this paragraph (g)(iv) provides that an
  adjustment shall become effective immediately after a Record Date for an
  event, the Company may defer until the occurrence of such event issuing to
  the holder of any share of Convertible Preferred Stock converted after such
  Record Date and before the occurrence of such event the additional Common
  Stock issuable upon such conversion by reason of the adjustment required by
  such event over and above the Common Stock issuable upon such conversion
  before giving effect to such adjustment.

    (11)  For purposes of this paragraph (g)(iv), the number of shares of Common
  Stock at any time outstanding shall not include shares held in the treasury
  of the Company but shall include shares issuable in respect of scrip
  certificates issued in lieu of fractions of Common Stock.  The Company shall
  not pay any dividend or make any distribution on Common Stock held in the
  treasury of the Company.

    (v)  In case of any consolidation of the Company with, or merger of the
  Company into, any other corporation, or in case of any merger of another
  corporation into the Company (other than a merger which does not result in
  any reclassification, conversion, exchange or cancellation of outstanding
  shares of Common Stock of the Company), or in case of any conveyance or
  transfer of the properties and assets of the Company substantially as an
  entirety, the holder of each share of Convertible Preferred Stock then
  outstanding shall have the right thereafter, during the period such
  Convertible Preferred Stock shall be convertible as specified in paragraph
  (g)(i), to convert such share of Convertible Preferred Stock only into the
  kind and amount of securities, cash and other property receivable upon such
  consolidation, merger, conveyance or transfer by a holder of the number of


                                       27
<PAGE>   28
  shares of Common Stock of the Company into which such share of Convertible
  Preferred Stock might have been converted immediately prior to such
  consolidation, merger, conveyance or transfer, assuming such holder of Common
  Stock of the Company failed to exercise his rights of election, if any, as to
  the kind or amount of securities, cash and other property receivable upon
  such consolidation, merger, conveyance or transfer (provided that, if the
  kind or amount of securities, cash and other property receivable upon such
  consolidation, merger, conveyance or transfer is not the same for each share
  of Common Stock of the Company in respect of which such rights of election
  shall not have been exercised ("nonelecting share"), then for the purpose of
  this paragraph (g)(v) the kind and amount of securities, cash and other
  property receivable upon such consolidation, merger, conveyance or transfer
  by each nonelecting share shall be deemed to be the kind and amount so
  receivable per share by a plurality of the nonelecting shares).  Such
  securities shall provide for adjustments which, for events subsequent to the
  effective date of the triggering event, shall be as nearly equivalent as may
  be practicable to the adjustments provided for in this paragraph (g)(v).  The
  above provisions of this Section shall similarly apply to successive
  consolidations, mergers, conveyances or transfers.

   (vi)  In case:

   (1) the Company shall declare a dividend (or any other distribution) on its
Common Stock payable otherwise than in cash out of its earned surplus; or

   (2) the Company shall authorize the granting to all holders of its Common
Stock of rights or warrants to subscribe for or purchase any shares of capital
stock of any class or of any other rights; or

   (3) of any reclassification of the Common Stock of the Company (other than a
subdivision or combination of its outstanding Common Stock), or of any
consolidation or merger to which the Company is a party and for which approval
of any shareholders of the Company is required, or the sale or transfer of all
or substantially all the assets of the Company; or


                                       28
<PAGE>   29
   (4) of the voluntary or involuntary dissolution, liquidation or winding up
of the Company;

then the Company shall cause to be filed with the Transfer Agent and at each
office or agency maintained for the purpose of conversion of the Convertible
Preferred Stock, and shall cause to be mailed to all holders at their last
addresses as they shall appear in the Convertible Preferred Stock Register, at
least 20 days (or 10 days in any case specified in clause (1) or (2) above)
prior to the applicable date hereinafter specified, a notice stating (x) the
date on which a record is to be taken for the purpose of such dividend,
distribution, rights or warrants, or, if a record is not to be taken, the date
as of which the holders of Common Stock of record to be entitled to such
dividend, distribution, rights or warrants are to be determined or (y) the date
on which such reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding up is expected to become effective, and the
date as of which it is expected that holders of Common Stock of record shall be
entitled to exchange their Common Stock for securities, cash or other property
deliverable upon such reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding up.  Failure to give the notice requested
by this Section or any defect therein shall not affect the legality or validity
of any dividend, distribution, right, warrant, reclassification, consolidation,
merger, sale, transfer, dissolution, liquidation or winding up, or the vote
upon any such action.

   (vii)  The Company shall at all times reserve and keep available, free from
preemptive rights, out of its authorized but unissued shares of Common Stock
(or out of its authorized shares of Common Stock held in the treasury of the
Company), for the purpose of effecting the conversion of the Convertible
Preferred Stock, the full number of Common Stock then issuable upon the
conversion of all outstanding shares of Convertible Preferred Stock.

   (viii)  The Company will pay any and all document, stamp or similar issue or
transfer taxes that may be payable in respect of the issue or delivery of
Common Stock on conversion of the Convertible Preferred Stock pursuant hereto.
The Company shall not, however, be required to pay any tax which may be payable
in respect of any transfer involved in the issue and delivery of shares of
Common Stock in a name other than that of the holder of the share of


                                       29
<PAGE>   30
Convertible Preferred Stock or the shares of Convertible Preferred Stock to be
converted, and no such issue or delivery shall be made unless and until the
Person requesting such issue has paid to the Company the amount of any such
tax, or has established to the satisfaction of the Company that such tax has
been paid.

   (ix)  (1)  Notwithstanding any other provision in the preceding paragraphs
to the contrary, if any Change in Control occurs then, if the Company does not
elect to make a Change in Control Offer, the Conversion Price in effect shall
be adjusted immediately after such Change in Control as described below.  In
addition, in the event of a Common Stock Change in Control (as defined in this
paragraph (g)(ix)), each share of the Convertible Preferred Stock shall be
convertible solely into common stock of the kind received by holders of Common
Stock as the result of such Common Stock Change in Control.  For purposes of
calculating any adjustment to be made pursuant to this paragraph in the event
of a Change in Control, immediately after such Change in Control:

    (A) in the case of a Non-Stock Change in Control (as defined in this
  paragraph (g)(ix)), the Conversion Price shall thereupon become the lower of
  (x) the Conversion Price in effect immediately prior to such Non-Stock Change
  in Control, but after giving effect to any other prior adjustments, and (y)
  the result obtained by multiplying the greater of the Applicable Price (as
  defined in this paragraph (g)(ix)) or the then applicable Reference Market
  Price (as defined in this paragraph (g)(ix)) by a fraction of which the
  numerator shall be $100.00 and the denominator shall be the then current
  Optional Redemption Price per share; and

    (B) in the case of a Common Stock Change in Control, the Conversion Price in
  effect immediately prior to such Common Stock Change in Control, but after
  giving effect to any prior adjustments, shall thereupon be adjusted by
  multiplying such Conversion Price by a fraction, of which the numerator shall
  be the Purchaser Stock Price (as defined in this paragraph (g)(ix)) and the
  denominator shall be the Applicable Price; provided, however, that in the
  event of a Common Stock Change in Control in which (x) 100% of the value of
  the consideration received by a holder of Common Stock is common stock of the
  successor, acquiror, or other third


                                       30
<PAGE>   31
  party (and cash, if any, is paid with respect to any fractional interests in
  such common stock resulting from such Common Stock Change in Control) and (y)
  all of the Common Stock will have been exchanged for, converted into, or
  acquired for, common stock (and cash with respect to fractional interests) of
  the successor, acquiror or other third party, the Conversion Price in effect
  immediately prior to such Common Stock Change in Control shall thereupon be
  adjusted by multiplying such Conversion Price by a fraction, of which the
  numerator shall be one (1) and the denominator shall be the number of shares
  of common stock of the successor, acquiror, or other third party received by
  a holder of one share of Common Stock as a result of such Common Stock Change
  in Control.

   (3)  For purposes of this paragraph (ix), the following terms shall have the
meanings indicated:

    "Applicable Price" means (i) in the event of a Non-Stock Change in Control
  in which the holders of the Common Stock receive only cash, the amount of
  cash received by the holder of one share of Common Stock and (ii) in the
  event of any other Non-Stock Change in Control or any Common Stock Change in
  Control, the average of the Closing Bid Prices for the Common Stock during
  the ten Trading Days prior to and including the record date for the
  determination of the holders of Common Stock entitled to receive cash,
  securities, property or other assets in connection with such Non-Stock Change
  in Control or Common Stock Change in Control or, if there is no such record
  date, the date upon which the holders of the Common Stock shall have the
  right to receive such cash, securities, property or other assets, in each
  case, as adjusted in good faith by the Board of Directors to appropriately
  reflect any of the events referred to in paragraph (g)(iv)(1) through (6).

    "Common Stock Change in Control" means any Change in Control in which more
  than 50% of the value (as determined in good faith by the Board of Directors
  of the Company) of the consideration received by holders of Common Stock
  consists of common stock that for each of the ten consecutive Trading Days
  referred to in the preceding paragraph has been admitted for listing or
  admitted for listing subject to notice of issuance on a national securities
  exchange or quoted on The Nasdaq


                                       31
<PAGE>   32
  National Market; provided, however, that a Change in Control shall not be a
  Common Stock Change in Control unless either (i) the Company continues to
  exist after the occurrence of such Change in Control and the outstanding
  shares of Convertible Preferred Stock continue to exist as outstanding shares
  of Convertible Preferred Stock, or (ii) not later than the occurrence of such
  Change in Control, the outstanding shares of Convertible Preferred Stock are
  converted into or exchanged for shares of convertible preferred stock of a
  corporation succeeding to the business of the Company, which convertible
  preferred stock has powers, preferences and relative, participating, optional
  or other rights, and qualifications, limitations and restrictions,
  substantially similar to those of the Convertible Preferred Stock.

    "Non-Stock Change in Control" means any Change in Control other than a
  Common Stock Change in Control.

    "Purchaser Stock Price" means, with respect to any Common Stock Change in
  Control, the product of (i) the number of shares of common stock received in
  such Common Stock Change of Control for each share of Common Stock, and (ii)
  the average of the per share Closing Prices for the common stock received in
  such Common Stock Change in Control for the ten consecutive Trading Days
  prior to and including the record date for the determination of the holders
  of Common Stock entitled to receive such common stock, or if there is no such
  record date, the date upon which the holders of the Common Stock shall have
  the right to receive such common stock, in each case, as adjusted in good
  faith by the Board of Directors to appropriately reflect any of the events
  referred to in paragraph (g)(iv)(1) through (6); provided, however, that if
  no such Closing Prices exist, then the Purchaser Stock Price shall be set at
  a price determined in good faith by the Board of Directors of the Company.

    "Reference Market Price" shall initially mean $13.50 (which is an amount
  equal to 66-2/3% of the reported last sale price for the Common Stock on The
  Nasdaq National Market on March 25, 1997), and in the event of any adjustment
  to the conversion prices other than as a result of a Change in Control, the
  Reference Market Price shall also be adjusted so that the ratio of the
  Reference Market Price to the Conversion Price


                                       32
<PAGE>   33
  after giving effect to any such adjustment shall always be the same as the
  ratio of $13.50 to the initial Conversion Price set forth in paragraph
  (g)(i).

   (h)  Change in Control.  (i)  Upon the occurrence of a Change of Control
(the date of such occurrence being the "Change in Control Date"), the Company
shall be obligated to (1) purchase all or a portion of each holder's
Convertible Preferred Stock in cash pursuant to the offer described in
paragraph (h)(iii) (the "Change of Control Offer") at a purchase price equal to
100% of the Liquidation Preference, plus, without duplication, all accrued and
unpaid Liquidated Damages and all accrued and unpaid dividends, if any, to the
Change of Control Payment Date, including an amount in cash equal to a prorated
dividend for the period from the Dividend Payment Date immediately prior to the
Change of Control Payment Date to the Change of Control Payment Date or (2)
adjust the conversion price as provided under paragraph (g)(ix).
Notwithstanding the foregoing, the Company shall, prior to electing to make a
Change of Control Offer, make an offer to redeem all outstanding shares of
Series 3 Preferred Stock.

   (ii)  Prior to the mailing of the notice referred to in paragraph (h)(iii),
but in any event within 15 days following the date on which the Company knows
or reasonably should have known that a Change in Control has occurred, the
Company covenants that it shall promptly determine if the purchase of the
Convertible Preferred Stock would violate or constitute a default under the
Indenture or other indebtedness of the Company.

   (iii)  Within 15 days following the date on which the Company knows or
reasonably should have known that a Change in Control has occurred, the Company
must send, by first-class mail, postage prepaid, a notice to each holder of
Convertible Preferred Stock.  Such notice shall state whether the Change of
Control Offer would be permitted under the Indenture or other indebtedness of
the Company, and if permitted, such notice shall contain all instructions and
materials necessary to enable such holders to tender Convertible Preferred
Stock pursuant to the Change of Control Offer.  If the Change of Control Offer
would be permitted under the Indenture or other indebtedness of the Company,
such notice shall state:

    (A) that a Change of Control has occurred, that the Change of Control Offer
  is being made pursuant to


                                       33
<PAGE>   34
  this paragraph (h) and that all Convertible Preferred Stock validly tendered
  and not withdrawn will be accepted for payment;

    (B) the purchase price (including the amount of accrued dividends, if any)
  and the purchase date (which must be no earlier than 30 days nor later than
  75 days from the date such notice is mailed, other than as may be required by
  law) (the "Change of Control Payment Date");

    (C) that any shares of Convertible Preferred Stock not tendered will
  continue to accrue dividends;

    (D) that, unless the Company defaults in making payment therefor, any share
  of Convertible Preferred Stock accepted for payment pursuant to the Change of

                                       35
<PAGE>   36
  Convertible Preferred Stock and shall (upon compliance with any applicable
  provisions of the laws of Delaware) have the status of authorized and
  unissued shares of Preferred Stock undesignated as to series and may be
  redesignated and reissued as part of any series of Preferred Stock; provided,
  however, that so long as any shares of Convertible Preferred Stock are
  outstanding, any issuance of such shares must be in compliance with the terms
  hereof.

   (j)  Business Day.  If any payment, redemption or exchange shall be required
by the terms hereof to be made on a day that is not a Business Day, such
payment, redemption or exchange shall be made on the immediately succeeding

States of America or any State thereof or the District of Columbia and the
Convertible Preferred Stock shall be converted into or exchanged for and shall
become shares of such successor, transferee or lessee, having in respect of
such successor, transferee or lessee substantially the same powers, preference
and relative participating, optional or other special rights and the
qualifications, limitations or restrictions thereon, that the Convertible
Preferred Stock had immediately prior to such transaction; and (2) the Company
delivers to the Transfer Agent an Officers' Certificate and an Opinion of
Counsel stating that such consolidation, merger or transfer complies with this
Certificate of Designation.  The successor, transferee or lessee will be the
successor company.

   (l)  Certificates.  (i)  Form and Dating.  The Convertible Preferred Stock
and the Transfer Agent's certificate of authentication shall be substantially

part of this Certificate of Designation.  The Convertible Preferred Stock
certificate may have notations, legends or endorsements required by law, stock
exchange rule, agreements to which the Company is subject, if any, or usage
(provided that any such notation, legend or endorsement is in a form acceptable
to the Company).  Each Convertible Preferred Stock certificate shall be dated
the date of its authentication.  The terms of the Convertible


                                       36
<PAGE>   37
Preferred Stock certificate set forth in Exhibit A are part of the terms of
this Certificate of Designation.

   (A)  Global Convertible Preferred Stock.  The Convertible Preferred Stock
sold in reliance on Rule 144A shall be issued initially in the form of one or
more fully registered global certificates with the global securities legend and
restricted securities legend set forth in Exhibit A hereto (the "Global
Convertible Preferred Stock"), which shall be deposited on behalf of the
purchasers represented thereby with the Transfer Agent, at its New York office,
as custodian for DTC (or with such other custodian as DTC may direct), and
registered in the name of DTC or a nominee of DTC, duly executed by the Company
and authenticated by the Transfer Agent as hereinafter provided.  The number of
shares of Convertible Preferred Stock represented by Global Convertible
Preferred Stock may from time to time be increased or decreased by adjustments
made on the records of the Transfer Agent and DTC or its nominee as hereinafter
provided.

   (B)  Book-Entry Provisions.  In the event Global Convertible Preferred Stock
is deposited with or on behalf of DTC, the Company shall execute and the
Transfer Agent shall authenticate and deliver initially one or more Global
Convertible Preferred Stock certificates that (a) shall be registered in the
name of DTC for such Global Convertible Preferred Stock or the nominee of DTC
and (b) shall be delivered by the Transfer Agent to DTC or pursuant to DTC's
instructions or held by the Transfer Agent as custodian for DTC.

   Members of, or participants in, DTC ("Agent Members") shall have no rights
under this Certificate of Designation with respect to any Global Convertible
Preferred Stock held on their behalf by DTC or by the Transfer Agent as the
custodian of DTC or under such Global Convertible Preferred Stock, and DTC may
be treated by the Company, the Transfer Agent and any agent of the Company or
the Transfer Agent as the absolute owner of such Global Convertible Preferred
Stock for all purposes whatsoever.  Notwithstanding the foregoing, nothing
herein shall prevent the Company, the Transfer Agent or any agent of the
Company or the Transfer Agent from giving effect to any written certification,
proxy or other authorization furnished by DTC or impair, as between DTC and its
Agent Members, the operation of customary practices of DTC governing the


                                       37
<PAGE>   38
exercise of the rights of a holder of a beneficial interest in any Global
Convertible Preferred Stock.

   (C)  Certificated Convertible Preferred Stock.  Convertible Preferred Stock
initially sold to certain "accredited investors" (as defined in Rule 501(a)(1),
(2), (3), (4), (5), (6) or (7) under the Securities Act) or sold in offshore
transactions pursuant to Regulation S under the Securities Act will be issued
in fully registered certificated form ("Certificated Convertible Preferred
Stock").

   Except as provided in this paragraph (l)(i) or in paragraph (l)(iii), owners
of beneficial interests in Global Convertible Preferred Stock will not be
entitled to receive physical delivery of Certificated Convertible Preferred
Stock.

   After a transfer of any Convertible Preferred Stock during the period of the
effectiveness of a Shelf Registration Statement with respect to such
Convertible Preferred Stock, all requirements pertaining to legends on such
Convertible Preferred Stock will cease to apply, the requirements requiring
that any such Convertible Preferred Stock issued to Holders be issued in global
form will cease to apply, and Certificated Convertible Preferred Stock without
legends will be available to the transferee of the Holder of such Convertible
Preferred Stock upon exchange of such transferring Holder's Convertible
Preferred Stock or directions to transfer such Holder's interest in the Global
Convertible Preferred Stock, as applicable.

   (ii)  Execution and Authentication.  Two Officers shall sign the Convertible
Preferred Stock for the Company by manual or facsimile signature.  The
Company's seal shall be impressed, affixed, imprinted or reproduced on the
Convertible Preferred Stock and may be in facsimile form.

   If an Officer whose signature is on Convertible Preferred Stock no longer
holds that office at the time the Transfer Agent authenticates the Convertible
Preferred Stock, the Convertible Preferred Stock shall be valid nevertheless.

   A Convertible Preferred Stock shall not be valid until an authorized
signatory of the Transfer Agent manually signs the certificate of
authentication on the Convertible Preferred Stock.  The signature shall be
conclusive evidence


                                       38
<PAGE>   39
that the Convertible Preferred Stock has been authenticated under this
Certificate of Designation.

   The Transfer Agent shall authenticate and deliver  1,000,000 shares of
Convertible Preferred Stock for original issue upon a written order of the
Company signed by two Officers or by an Officer and either an Assistant
Treasurer or an Assistant Secretary of the Company.  In addition, the Transfer
Agent shall authenticate and deliver, from time to time, Additional Shares for
original issue upon order of the Company signed by two Officers or by an
Officer or either an Assistant Treasurer or Assistant Secretary of the Company.
Such orders shall specify the number of shares of Convertible Preferred Stock
to be authenticated and the date on which the original issue of Convertible
Preferred Stock is to be authenticated.

   The Transfer Agent may appoint an authenticating agent reasonably acceptable
to the Company to authenticate the Convertible Preferred Stock.  Unless limited
by the terms of such appointment, an authenticating agent may authenticate
Convertible Preferred Stock whenever the Transfer Agent may do so.  Each
reference in this Certificate of Designation to authentication by the Transfer
Agent includes authentication by such agent.  An authenticating agent has the
same rights as the Transfer Agent or agent for service of notices and demands.

   (iii)  Transfer and Exchange.  (A)  Transfer and Exchange of Certificated
Convertible Preferred Stock.  When Certificated Convertible Preferred Stock is
presented to the Transfer Agent with a request to register the transfer of such
Certificated Convertible Preferred Stock or to exchange such Certificated
Convertible Preferred Stock for an equal number of shares of Certificated
Convertible Preferred Stock of other authorized denominations, the Transfer
Agent shall register the transfer or make the exchange as requested if its
reasonable requirements for such transaction are met; provided, however, that
the Certificated Convertible Preferred Stock surrendered for transfer or
exchange:

    (1) shall be duly endorsed or accompanied by a written instrument of
  transfer in form reasonably satisfactory to the Company and the Transfer
  Agent, duly executed by the Holder thereof or its attorney duly authorized in
  writing; and


                                       39
<PAGE>   40

 Convertible Preferred Stock, are being transferred or exchanged pursuant to
 an effective registration statement under the Securities Act or pursuant to
 clause (I), (II) or (III) below, and are accompanied by the following
 additional information and documents, as applicable:

     (I) if such Transfer Restricted Securities are being delivered to the
   Transfer Agent by a Holder for registration in the name of such Holder,
   without transfer, a certification from such Holder to that effect in
   substantially the form of Exhibit C hereto; or

     (II) if such Transfer Restricted Securities are being transferred to the
   Company or to a "qualified institutional buyer" ("QIB") in accordance with
   Rule 144A under the Securities Act or pursuant to an exemption from
   registration in accordance with Rule 144 or Regulation S under the
   Securities Act, a certification to that effect (in substantially the form of
   Exhibit C hereto); or

     (III) if such Transfer Restricted Securities are being transferred to an
   "accredited investor" as described in Rule 501(a)(1), (2), (3), (4), (5),
   (6) or (7) under the Securities Act that is acquiring the Securities for its
   own account, or for the account of such an accredited investor, in each case
   in a minimum principal amount of $100,000 for investment purposes and not
   with a view to, or for offer or sale in connection with, any distribution in
   violation of the Securities Act, or in reliance on another exemption from
   the registration requirements of the Securities Act: a certification to that
   effect in substantially the form of Exhibit C hereto, and if the Company or
   the Transfer Agent so requests, evidence reasonably satisfactory to them as
   to the compliance with the restrictions set forth in the legend set forth in
   paragraph (l)(iii)(G)(1) below.

   (B)  Restrictions on Transfer of Certificated Convertible Preferred Stock
for a Beneficial Interest in Global Convertible Preferred Stock.  Certificated

                                       40
<PAGE>   41
beneficial interest in Global Convertible Preferred Stock except upon
satisfaction of the requirements set forth below.  Upon receipt by the
Transfer Agent of Certificated Convertible Preferred Stock, duly endorsed or
accompanied by appropriate instruments of transfer, in form satisfactory to
the Transfer Agent, together with:

     (1) if such Certificated Convertible Preferred Stock is a Transfer
  Restricted Security, certification that such Certificated Convertible
  Preferred Stock is being transferred to a QIB in accordance with Rule 144A
  under the Securities Act; and

  Transfer Restricted Security, written instructions directing the Transfer
  Agent to make, or to direct DTC to make, an adjustment on its books and
  records with respect to such Global Convertible Preferred Stock to reflect an
  increase in the number of shares of Convertible Preferred Stock represented
  by the Global Convertible Preferred Stock,

then the Transfer Agent shall cancel such Certificated Convertible Preferred
Stock and cause, or direct DTC to cause, in accordance with the standing
instructions and procedures existing between DTC and the Transfer Agent, the
number of shares of Convertible Preferred Stock represented by the Global
Convertible Preferred Stock to be increased accordingly.  If no Global
Convertible Preferred Stock is then outstanding, the Company shall issue and
the Transfer Agent shall authenticate, upon written order of the Company in the
form of an Officers' Certificate, a new Global Convertible Preferred Stock
representing the appropriate number of shares.

   (C)  Transfer and Exchange of Global Convertible Preferred Stock.  The
transfer and exchange of Global Convertible Preferred Stock or beneficial
interests therein shall be effected through DTC, in accordance with this

       (1)  Any person having a beneficial interest in Convertible Preferred
   Stock that is being transferred or exchanged pursuant to an effective
   registration statement under the Securities Act or pursuant to clause (I),
   (II) or (III) below may upon request, and if accompanied by the information
   specified below, exchange such beneficial interest for Certificated
   Convertible Preferred Stock representing the same number of shares of
   Convertible Preferred Stock.  Upon receipt by the Transfer Agent of written
   instructions or such other form of instructions as is customary for DTC from
   DTC or its nominee on behalf of any person having a beneficial interest in
   Global Convertible Preferred Stock and upon receipt by the Transfer Agent of
   a written order or such other form of instructions as is customary for DTC
   or the person designated by DTC as having such a beneficial interest in a
   Transfer Restricted Security only, and upon the following additional
   information and documents (all of which may be submitted by facsimile):

       (I) if such beneficial interest is being transferred to the person
     designated by DTC as being the owner of a beneficial interest in Global
     Convertible Preferred Stock, a certification from such person to that
     effect (in substantially the form of Exhibit C hereto);

       (II) if such beneficial interest is being transferred to a QIB in
     accordance with Rule 144A under the Securities Act or pursuant to an
     exemption from registration in accordance with Rule 144 or Regulation S
     under the Securities Act, a certification to that effect (in substantially

     investor" as described in Rule 501(a)(1), (2), (3), (4), (5), (6) or (7)
     under the Securities Act that is acquiring the security for its own
     account, or for the account of such an accredited investor, in each case in
     a minimum principal amount of $100,000 for investment purposes and not with
     a view to, or for offer or sale in connection with, any distribution in
     violation of the Securities Act, or in reliance on another exemption from
     the registration requirements of the Securities Act, a


                                       42
<PAGE>   43
  certification to that effect from the transferor (in substantially the form
  of Exhibit C hereto), and if the Company or the Transfer Agent so requests,
  evidence reasonably satisfactory to them as to the compliance with the
  restrictions set forth in the legend set forth in paragraph (l)(iii)(G)(1)
  below;

then, the Transfer Agent or DTC, at the direction of the Transfer Agent, will
cause, in accordance with the standing instructions and procedures existing
between DTC and the Transfer Agent, the number of shares of Convertible
Preferred Stock represented by Global Convertible Preferred Stock to be reduced
on its books and records and, following such reduction, the Company will
execute and the Transfer Agent will authenticate and deliver to the transferee
Certificated Convertible Preferred Stock.

    (2)  Certificated Convertible Preferred Stock issued in exchange for a
  beneficial interest in a Global Convertible Preferred Stock pursuant to this
  paragraph (l)(iii)(D) shall be registered in such names and in such
  authorized denominations as DTC, pursuant to instructions from its direct or

a nominee of DTC or by a nominee of DTC to DTC or another nominee of DTC or by
DTC or any such nominee to a successor depository or a nominee of such
successor depository.

  depository for the Global Convertible Preferred Stock and a successor
  depository for the Global Convertible Preferred Stock is not appointed by the
  Company within 90 days after delivery of such notice;

  Event; or

    (4) the Company, in its sole discretion, notifies the Transfer Agent in
  writing that it elects to cause the issuance of Certificated Convertible
  Preferred Stock under this Certificate of Designation,

then the Company will execute, and the Transfer Agent, upon receipt of a
written order of the Company signed by two Officers or by an Officer and either
an Assistant Treasurer or an Assistant Secretary of the Company requesting the
authentication and delivery of Certificated Convertible Preferred Stock to the
persons designated by the Company, will authenticate and deliver Certificated

  SECURITIES ACT OF 1933 (THE "SECURITIES ACT") AND MAY NOT BE OFFERED, SOLD,
  PLEDGED OR OTHERWISE TRANSFERRED IN ABSENCE OF SUCH REGISTRATION OR AN
  APPLICABLE EXEMPTION THEREFROM.  EACH PURCHASER OF THE SECURITY EVIDENCED

  HEREBY NOTIFIED THAT THE SELLER MAY BE RELYING ON THE EXEMPTION FROM THE
  PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A
  THEREUNDER.  THE HOLDER OF THE SECURITY EVIDENCED HEREBY (AND OF THE COMMON
  STOCK INTO WHICH THIS SECURITY IN CONVERTIBLE) AGREES FOR THE


                                       44
<PAGE>   45
  BENEFIT OF THE COMPANY THAT (A) SUCH SECURITY (AND THE COMMON STOCK INTO
  WHICH THIS SECURITY IS CONVERTIBLE) MAY BE RESOLD, PLEDGED OR OTHERWISE
  TRANSFERRED, ONLY (1) TO A PERSON WHO THE SELLER REASONABLY BELIEVES IS A
  QUALIFIED INSTITUTIONAL BUYER WITHIN THE MEANING OF RULE 144A UNDER THE
  SECURITIES ACT PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A
  QUALIFIED INSTITUTIONAL BUYER IN A TRANSACTION MEETING THE REQUIREMENTS OF
  RULE 144A, (2) IN AN OFFSHORE TRANSACTION COMPLYING WITH RULE 904 OF
  REGULATION S UNDER THE SECURITIES ACT, (3) PURSUANT TO AN EXEMPTION FROM

   (2)  Upon any sale or transfer of a Transfer Restricted Security (including
any Transfer Restricted Security represented by Global Convertible Preferred
Stock) pursuant to Rule 144 under the Securities Act or an effective
registration statement under the Securities Act:

     (I) in the case of any Transfer Restricted Security that is a Certificated
   Convertible Preferred Stock, the Transfer Agent shall permit the Holder
   thereof to exchange such Transfer Restricted Security for a Certificated
   Convertible Preferred Stock that does not bear the legend set forth above
   and rescind any restriction on the transfer of such Transfer Restricted
   Security; and

     (II) in the case of any Transfer Restricted Security that is represented
   by a Global Convertible Preferred Stock, the Transfer Agent shall permit the
   Holder thereof to exchange such Transfer Restricted Security for a
   Certificated Convertible Preferred Stock Security that does not bear the
   legend set forth above and rescind any restriction on the transfer of such
   Transfer Restricted Security, if the Holder's request for such exchange was
   made in reliance on Rule 144 and the Holder certifies to that effect in
   writing to the Transfer Agent (such certification to be in the form set
   forth on the reverse of the Transfer Restricted Security).


                                       45
<PAGE>   46
   (H)  Cancellation or Adjustment of Global Convertible Preferred Stock.  At
such time as all beneficial interests in Global Convertible Preferred Stock
have either been exchanged for Certificated Convertible Preferred Stock,
redeemed, repurchased or canceled, such Global Convertible Preferred Stock
shall be returned to DTC for cancellation or retained and canceled by the
Transfer Agent.  At any time prior to such cancellation, if any beneficial
interest in Global Convertible Preferred Stock is exchanged for Certificated
Convertible Preferred Stock, redeemed, repurchased or canceled, the number of
shares of Convertible Preferred Stock represented by such Global Convertible
Preferred Stock shall be reduced and an adjustment shall be made on the books
and records of the Transfer Agent with respect to such Global Convertible
Preferred Stock, by the Transfer Agent or DTC, to reflect such reduction.

   (I)  Obligations with Respect to Transfers and Exchanges of Convertible
Preferred Stock.  (1) To permit registrations of transfers and exchanges, the
Company shall execute and the Transfer Agent shall authenticate Certificated
Convertible Preferred Stock and Global Convertible Preferred Stock as required
pursuant to the provisions of this paragraph (iii).

    (2)  All Certificated Convertible Preferred Stock and Global Convertible
  Preferred Stock issued upon any registration of transfer or exchange of
  Certificated Convertible Preferred Stock or Global Convertible Preferred
  Stock shall be the valid obligations of the Company, entitled to the same
  benefits under this Certificate of Designation as the Certificated
  Convertible Preferred Stock or Global Convertible Preferred Stock surrendered
  upon such registration of transfer or exchange.

    (3)  Prior to due presentment for registration of transfer of any shares of
  Convertible Preferred Stock, the Transfer Agent and the Company may deem and
  treat the person in whose name such shares of Convertible Preferred Stock are
  registered as the absolute owner of such Convertible Preferred Stock and
  neither the Transfer Agent nor the Company shall be affected by notice to the
  contrary.

    (4)  No service charge shall be made to a Holder for any registration of
  transfer or exchange upon surrender of any Convertible Preferred Stock


                                       46
<PAGE>   47
Certificate at the office of the Transfer Agent maintained for that purpose.
However, the Company may require payment of a sum sufficient to cover any tax
or other governmental charge that may be imposed in connection with any
registration of transfer or exchange of Convertible Preferred Stock
Certificates.

  (5)  Upon any sale or transfer of shares of Convertible Preferred Stock
(including any Convertible Preferred Stock represented by a Global
Convertible Preferred Stock Certificate) pursuant to an effective
registration statement under the Securities Act, pursuant to Rule 144 under
the Securities Act or pursuant to an opinion of counsel reasonably
satisfactory to the Company that no legend is required:

   (A)   in the case of any Certificated Convertible Preferred Stock, the
         Transfer Agent shall permit the holder thereof to exchange such
         Convertible Preferred Stock for Certificated Convertible Preferred
         Stock that does not bear the legend set forth in paragraph (iii)(G)
         above and rescind any restriction on the transfer of such Convertible
         Preferred Stock; and

   (B)   in the case of any Global Convertible Preferred Stock, such
         Convertible Preferred Stock shall not be required to bear the legend
         set forth in paragraph (iii)(G) above but shall continue to be subject
         to the provisions of paragraph (iii)(D) hereof; provided, however,
         that with respect to any request for an exchange of Convertible
         Preferred Stock that is represented by Global Convertible Preferred
         Stock for Certificated Convertible Preferred Stock that does not bear
         the legend set forth in paragraph (iii)(G) above in connection with a
         sale or transfer thereof pursuant to Rule 144 (and based upon an
         opinion of counsel if the Company so requests), the Holder thereof
         shall certify in writing to the Transfer Agent that such request is
         being made pursuant to Rule 144 (such certification to be
         substantially in the form of Exhibit C hereto).


                                       47
<PAGE>   48
     (iv)  Replacement Certificates.  If a mutilated Convertible Preferred
  Stock certificate is surrendered to the Transfer Agent or if the Holder of a
  Convertible Preferred Stock certificate claims that the Convertible Preferred
  Stock certificate has been lost, destroyed or wrongfully taken, the Company
  shall issue and the Transfer Agent shall countersign a replacement
  Convertible Preferred Stock certificate if the reasonable requirements of the
  Transfer Agent and of Section 8-405 of the Uniform Commercial Code as in
  effect in the State of New York are met.  If required by the Transfer Agent
  or the Company, such Holder shall furnish an indemnity bond sufficient in the
  judgment of the Company and the Transfer Agent to protect the Company and the
  Transfer Agent from any loss which either of them may suffer if a Convertible
  Preferred Stock certificate is replaced.  The Company and the Transfer Agent
  may charge the Holder for their expenses in replacing a Convertible Preferred
  Stock certificate.

     (v)  Temporary Certificates.  Until definitive Convertible Preferred Stock
  certificates are ready for delivery, the Company may prepare and the Transfer
  Agent shall countersign temporary Convertible Preferred Stock certificates.
  Temporary Convertible Preferred Stock certificates shall be substantially in
  the form of definitive Convertible Preferred Stock certificates but may have
  variations that the Company considers appropriate for temporary Convertible
  Preferred Stock certificates.  Without unreasonable delay, the Company shall
  prepare and the Transfer Agent shall countersign definitive Convertible
  Preferred Stock certificates and deliver them in exchange for temporary
  Convertible Preferred Stock certificates.

     (vi)  Cancellation.  (A) In the event the Company shall purchase or
  otherwise acquire Certificated Convertible Preferred Stock, the same shall
  thereupon be delivered to the Transfer Agent for cancellation.

   (B)  At such time as all beneficial interests in Global Convertible
Preferred Stock have either been exchanged for Certificated Convertible
Preferred Stock, redeemed, repurchased or canceled, such Global Convertible

Ladies and Gentlemen:

   In connection with our proposed purchase of certain 7 1/4% Junior
Convertible Preferred Stock Due 2007 (the "Convertible Preferred Stock"), of
IXC Communications, Inc., a Delaware corporation (the "Company"), we represent
that:

    (i) we are an "accredited investor" within the meaning of Rule
  501(a)(1),(2),(3),(4),(5),(6) or (7) under the Securities Act of 1933 (the
  "Securities Act") (an "Accredited Investor"), or an entity in which all of
  the equity owners are Accredited Investors;

    (ii) any purchase of Convertible Preferred Stock will be for our own account
  or for the account of one or more other Accredited Investors as to which we
  exercise sole investment discretion;

    (iii) we have such knowledge and experience in financial and business
  matters that we are capable of evaluating the merits and risks of purchasing
  Convertible Preferred Stock and we and any accounts for which we are acting
  are able to bear the economic risks of our or their investment;

    (iv) we are not acquiring Convertible Preferred Stock with a view to any
  distribution thereof in a transaction that would violate the Securities Act
  or the securities laws of any State of the United States or any other
  applicable jurisdiction; provided that the disposition of our property and
  the property of any accounts for which we are acting as fiduciary shall
  remain at all times without our control; and

    (v) we acknowledge that we have had access to such financial and other
  information, and have been afforded the opportunity to ask such questions of
  representatives of the Company and receive answers
<PAGE>   66
   thereto, as we deem necessary in connection with our decision to purchase
   Convertible Preferred Stock.

   We understand that the Convertible Preferred Stock has not been registered
under the Securities Act, and we agree, on our own behalf and on behalf of each
account for which we acquire any Convertible Preferred Stock, that such
Convertible Preferred Stock may be offered, resold, pledged or otherwise
transferred only (i) to a person whom we reasonably believe to be a qualified
institutional buyer (as defined in Rule 144A under the Securities Act) in a
transaction meeting the requirements of Rule 144A, in a transaction meeting the
requirements of Rule 144 under the Securities Act, outside the United States to
a foreign person in a transaction meeting the requirements of Rule 904 under
the Securities Act (and, unless such transfer occurs in a transaction meeting
the requirements of Rule 144A, based upon an opinion of counsel, if the Company
so requests), (ii) to the Company or (iii) pursuant to an effective
registration statement, and, in each case, in accordance with any applicable
securities laws of any State of the United States or any other applicable
jurisdiction.  We understand that the registrar will not be required to accept
for registration of transfer any shares of Convertible Preferred Stock, except
upon presentation of evidence satisfactory to the Company that the foregoing
restrictions on transfer have been complied with.  We further understand that
the Convertible Preferred Stock purchased by us will bear a legend reflecting
the substance of this paragraph.  We further agree to provide to any person
acquiring any of the Convertible Preferred Stock from us a notice advising such
person that resales of the Convertible Preferred Stock are restricted as stated
herein.

   We acknowledge that you, the Company and others will rely upon our
confirmations, acknowledgements and agreements set forth herein, and we agree
to notify you promptly in writing if any of our representations or warranties
herein ceases to be accurate and complete.
