              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)
 
1. BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES
 
     The accompanying unaudited Condensed Consolidated Financial Statements have
been prepared in accordance with generally accepted accounting principles for
interim financial information and with the instructions to Form 10-Q and Article
10 of Regulation S-X. Accordingly, they do not include all of the information
and notes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments (consisting
of normal recurring accruals) considered necessary for a fair presentation for
the periods indicated have been included. Operating results for the three and
nine month periods ended September 30, 1998 are not necessarily indicative of
the results that may be expected for the year ended December 31, 1998. The
accompanying unaudited Condensed Consolidated Financial Statements have been
restated for all periods presented to include the operations of Eclipse
Telecommunications, Inc., formerly Network Long Distance, Inc. ("Eclipse"),which
was acquired on June 3, 1998, in a transaction accounted for as a pooling of
interests (See Note 2). The Condensed Consolidated Balance Sheet at December 31,
1997 has been derived from the audited financial statements for the Company but
does not include all of the information and notes required by generally accepted
accounting principles for complete financial statements. The accompanying
financial statements should be read in conjunction with the Company's audited
consolidated financial statements and notes thereto for the year ended December
31, 1997. Certain amounts shown in the Company's 1997 financial statements have
been reclassified to conform to the 1998 presentation.
 
2. MERGER WITH ECLIPSE
 
     On June 3, 1998, the Company completed the acquisition of Eclipse through a
merger of a Company subsidiary with Eclipse by exchanging approximately 4.05
million shares of its common stock for all of the outstanding common stock of
Eclipse. Each share of Eclipse common stock was exchanged for .2998 shares of
the Company's common stock. In addition, outstanding Eclipse stock options were
converted at the same exchange factor into options to purchase shares of the
Company's common stock. Prior to the merger, Eclipse's fiscal year ended on
March 31. Therefore the reported 1997 year-end balance sheet information for
Eclipse represents its financial position as of March 31, 1998. In order to
report the movement in cash for the first six months of 1998, a $1.5 million
adjustment was reported in the condensed consolidated statement of cash flows,
representing Eclipse's first quarter 1998 net income, which was in both the
beginning retained earnings balance and the current period's net income.
 
     The merger constituted a tax-free reorganization and has been accounted for
as a pooling of interests. Accordingly, all prior period consolidated financial
statements have been restated to include the combined results of operations,
financial position and cash flows of Eclipse as though it had always been a part
of the Company.
 
     In connection with the merger, the Company recorded charges amounting to
$8.1 million for merger related costs, including professional services
associated with the merger, termination costs associated with duplicate
functions, costs of exiting excess office space and the write-off of duplicate
equipment and software.
 
3. INVESTMENTS IN UNCONSOLIDATED SUBSIDIARIES
 
  PSINet
 
     On February 25, 1998, the Company consummated agreements with PSINet, Inc.
("PSINet") which allow each party to market and sell the products and services
of the other party. Under the terms of the agreements, the Company will provide
PSINet with an indefeasible right to use ("IRU") 10,000 miles of OC-48
transmission capacity on its network over a 20-year period in exchange for
approximately 10.2 million shares representing under 20% (post-issuance) of
PSINet common stock. If the value of the PSINet common stock received by the
Company is less than $240.0 million at the earlier of one year after the final
delivery of the transmission capacity (scheduled for late-1999) or February 26,
2002, PSINet will deliver to IXC either

        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
cash or additional PSINet common stock such that the value of the total
consideration paid by PSINet is $240.0 million. The Company receives a
maintenance fee which, as the full capacity is delivered, is expected to
increase to approximately $11.5 million per year. Revenue from the IRU will be
recognized over its term of 20 years as the capacity is delivered.
 
     From the transaction date through May 1998, the Company accounted for its
investment in PSINet under the equity method since the Company was deemed to
have significant influence over PSINet based on its level of ownership. In June
1998, the Company changed from the equity method to the cost method due to a
reduced level of ownership. At September 30, 1998 the Company's recorded
investment in PSINet was approximately $133.1 million.
 
  Marca-Tel
 
     As of September 30, 1998, the Company indirectly owned 24.5% of Marca-Tel
S.A. de C.V. ("Marca-Tel") through its ownership of 50% of Progress
International LLC ("Progress International"), which owns a holding company that
owns 49% of Marca-Tel. The remaining 51% of Marca-Tel is owned by a Mexican
individual and a subsidiary of Formento Radio Beep, S.A. de C.V. The other 50%
of Progress International is owned by Westel International, Inc ("Westel"). The
Company's investment in Progress is negative $12.8 million as of September 30,
1998 due to the recognized equity losses being greater than the Company's
funding of its investment. Summary financial information and the equity losses
recorded by the Company for Marca-Tel are as follows (in thousands):

     In June 1998 the Company obtained a note receivable from Westel for $14.9
million of advances that the Company had made to Progress International on
Westel's behalf. The note receivable from Westel is secured by a portion of
Westel's investment in Progress. As of September 30, 1998, the balance of the
note receivable was $12.9 million. In October 1998, Marca-Tel received a notice
of default from its primary external financing source. Representatives of the
Marca-Tel partners and the financing source are attempting to resolve this
issue. Based on these discussions, the Company's indirect interest in Marca-Tel
could be diluted or lost entirely.
 
4. NOTE RECEIVABLE
 
     During the second quarter of 1998, the Company activated a previously
signed IRU with a customer in exchange for a note that is payable over an
18-month period bearing interest at 12%. At September 30, 1998, $94.1 million
was outstanding under the note receivable.
 
5. 9% SENIOR SUBORDINATED NOTES DUE 2008
 
     On April 21, 1998, the Company issued $450.0 million of 9% Senior
Subordinated Notes Due 2008 (the "9% Senior Subordinated Notes"). In connection
with the sale of the 9% Senior Subordinated Notes, the Company completed its
tender offer to purchase for cash all of its outstanding 12 1/2% Senior Notes
Due 2005 (the "Old Notes"). Pursuant to the terms of the tender offer, $284.2
million (out of $285.0 million) in aggregate principal amount of the Old Notes
were tendered and accepted for payment by the Company. The Company used
approximately $342.7 million of the estimated $435.6 million net proceeds of the
9% Senior Subordinated Notes offering to pay the tender offer price for the Old
Notes. With the early extinguishment of
 
                                        7

                   IXC COMMUNICATIONS, INC. AND SUBSIDIARIES
 
        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
the Old Notes, a charge of approximately $69.6 million was recorded as an
extraordinary item net of related tax benefit in the second and third quarters
of 1998.
 
     The 9% Senior Subordinated Notes are general unsecured obligations of the
Company and will be subordinate in right of payment to all existing and future
senior indebtedness of the Company and other liabilities of the Company's
subsidiaries. In connection with the consummation of the tender offer, the Old
Notes were amended to eliminate substantially all of the restrictive covenants
therein and all guarantees given thereunder.
 
6. 6 3/4% CUMULATIVE CONVERTIBLE PREFERRED STOCK
 
     In March and April 1998, the Company sold $155.3 million of 6 3/4%
Cumulative Convertible Preferred Stock ("6 3/4% Convertible Preferred Stock")
issued in the form of depositary shares (3,105,000 depositary shares at $50 per
share; each depositary share represents 1/20 of a share of 6 3/4% Convertible
Preferred Stock at $1,000 per share). The net proceeds of approximately $147.2
million from the offering are being used to fund capital expenditures, including
a portion of the network expansion, and for general corporate purposes,
including acquisitions of related businesses or interests therein and joint
ventures. The 6 3/4% Convertible Preferred Stock can be converted at the option
of the holder thereof into shares of Common Stock, par value $.01 per share, of
the Company at any time unless previously redeemed or repurchased, at a
conversion rate of 0.6874 shares of common stock per depositary share (13.748
shares of Common Stock per share of the 6 3/4% Convertible Preferred Stock).
Dividends on the 6 3/4% Convertible Preferred Stock are payable quarterly in
arrears in cash or Common Stock, under certain circumstances, on January 1,
April 1, July 1 and October 1 of each year, commencing on July 1, 1998.
 
7. SERIES 3 REDEMPTION
 
     On March 31, 1998, the Company redeemed the remaining 414 shares of its 10%
Junior Series 3 Cumulative Redeemable Preferred Stock outstanding for
approximately $0.7 million in cash ($1,000 per share, plus $0.3 million of
accrued and unpaid dividends).
 
8. INCOME TAXES
 
     The provision for income taxes recorded during interim periods is
calculated based on an estimated annual effective tax rate. For 1998, the
effective tax rate is negative and includes the impact of gains from the
transactions with PSINet (see Note 3) and other IRU transactions that have
already occurred and others that are expected to occur later in the year. The
Company has applied a valuation allowance against the deferred tax assets
arising during 1998 due to the uncertainty of realization.
 
9. COMMITMENTS AND CONTINGENCIES
 
     The Company has made and will continue to make material commitments related
to the expansion of its network.
 
     The Company entered into several agreements with major long distance
carriers for the sale of dark fiber and capacity usage. Although these
agreements provide for certain penalties if the Company does not complete
construction of the defined routes within the time frame specified in the
agreements, management does not anticipate that the Company will incur any
substantial penalties under these provisions.
 
     From time to time the Company is involved in various legal proceedings
arising in the ordinary course of business, some of which are covered by
insurance. In the opinion of the Company's management, none of the claims
relating to such proceedings will have a material effect on the financial
condition or results of operations of the Company.

     The following table summarizes securities outstanding as of the end of each

future. Such securities were excluded from the computation above since they
would have been anti-dilutive due to the Company's net loss. The figures
presented for the 6 3/4% Convertible Preferred Stock and the 7 1/4% Junior

13.748 common shares and 4.263 common shares, respectively.

11. STOCKHOLDER RIGHTS PLAN
 
     In September 1998 the Company's Board of Directors declared a dividend of
one Preferred Share Purchase Right on each outstanding share of its Common
Stock. Each Right entitles the holder to buy one one-thousandth of a share of
new Series A Junior Participating Preferred Stock of the Company at an exercise
price of $210.00 per Right. The Rights will be exercisable if a person or group
acquires 20% or more of the Common Stock of the Company (or if a stockholder of
the Company currently holding more than 20% of the outstanding stock of the
Company acquires any additional shares of Common Stock) or announces a tender
offer for 20% or more of the Common Stock. The Company will be entitled to
redeem the Rights at one cent per Right at any time before any such person
acquires 20% or more of the outstanding Common Stock. Each Right will entitle
its holder to purchase, at the Right's exercise price, a number of shares of
Common Stock having a market value at that time of twice the Right's exercise
price. Rights held by the 20% or more holder will become void and will not be
exercisable to purchase shares at the bargain purchase price. If the Company is
acquired in a merger or other business combination transaction after a person
acquires 20% or more of the Company's Common Stock, each Right will entitle its
holder to purchase, at the Right's then-current exercise price, a number of the
acquiring company's common shares having a market value at that time of twice

Right's exercise price. The dividend distribution was payable to stockholders of
record on September 20, 1998. The Rights will expire on September 20, 2008.
 
12. STOCKHOLDERS' EQUITY
 
     On July 29, 1998, the Company's Board of Directors approved a two-for-one
split of the Company's common stock. The directors also approved an increase in
the authorized number of shares of common stock to 300 million shares and the
creation of a new class of Series B preferred stock for future use by the
Company. Authorized shares of the new Series B preferred stock will be 17
million. The effective date for the stock split and change in capital structure
was originally anticipated to occur in September 1998; however, in September
1998 these actions were postponed.
 
     During the third quarter the Company's Board of Directors adopted and the
Company's stockholders approved the Company's 1998 Stock Plan and reserved
3,150,000 shares for issuance thereunder. The 1998 Stock Plan provides for the
grant of incentive stock options, non-qualified stock options, and restricted
stock to employees, directors, and others, with grants generally having exercise
prices equal to the fair market value of the Company's common stock at the date
of grant. Options and restricted stock granted under the plan vest in four equal
annual installments and expire after 10 years.
 
13. SUBSEQUENT EVENTS
 
     On October 28, 1998, the Company entered into a $600 million senior secured
credit facility with a syndicate of commercial banks. The Company received
funding under the credit facility of $200 million, less $4.2 million of
transaction costs. The senior secured credit facility consists of a $150 million
revolving facility, a $200 million term loan facility, and an uncommitted
special purpose loan facility of $250 million. The Company must comply with
various financial and other covenants on an ongoing basis in addition to meeting
the covenants on a pro forma basis prior to drawing additional amounts under the
credit facility. Loans outstanding under the credit facility bear interest at
either LIBOR or the lead commercial bank's prime rate plus applicable margins.
 
14. NEW ACCOUNTING PRONOUNCEMENTS
 
     In September 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income" ("SFAS No. 130"). SFAS No. 130 establishes standards for reporting and
display of comprehensive income and its components in a full set of
general-purpose financial statements. SFAS No. 130 is effective for fiscal years
beginning after December 15, 1997. Due to the Company having no items of other
comprehensive income in any of the periods presented, the adoption of SFAS No.
130 had no impact on the Company's reporting or display of financial information
at September 30, 1998.
 
     Also in September 1997, the FASB issued SFAS No. 131, "Disclosures about
Segments of an Enterprise and Related Information" ("SFAS No. 131"). SFAS No.
131 establishes standards for the way that public business enterprises report
information about operating segments in annual financial statements and requires
that those enterprises report selected information about operating segments in
interim financial reports issued to stockholders. SFAS No. 131 is effective for
financial statements for fiscal years beginning after December 15, 1997. Interim
period reporting of segment information is not required in the first year of
adoption. The adoption of SFAS No. 131 will have no impact on the Company's
consolidated results of operations, financial position or cash flows but will
affect the disclosure of segment information.
 
     In September 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities" ("SFAS No. 133"). SFAS No. 133 establishes
accounting and reporting standards requiring that every derivative instrument
(including certain derivative instruments embedded in other contracts) be
recorded in the balance sheet as either an asset or liability measured at its
fair value. SFAS No. 133 requires that changes in the derivative's fair value be
recognized currently in earnings unless specific hedge accounting criteria are
met. Special accounting for qualifying hedges allows a derivative's gains and
 
                                       10

        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
losses to offset related results on the hedged item in the income statement, and
requires that a company must formally document, designate, and assess the
effectiveness of transactions that receive hedge accounting. Because the Company
has not entered into derivative financial instruments, the implementation of
SFAS No. 133 will not have a material impact on the Company's consolidated
results of operations, financial position or cash flows.
 
     In April 1998, the Accounting Standards Executive Committee issued
Statement of Position ("SOP") 98-5, "Reporting on the Costs of Start-Up
Activities". The SOP requires costs of start-up activities and organization
costs to be expensed as incurred, and is effective for fiscal years beginning
after December 15, 1998. The effects of adoption must be reported as a
cumulative change in accounting principle. The Company expects that it will
record a cumulative effect of a change in accounting to write off all
unamortized start-up costs on its balance sheet at January 1, 1999 in its first
quarter ended March 31, 1999; however, the Company has not yet quantified the
amount of this write-off.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS
 
     Except for the historical information contained below, the matters
discussed in this item are forward-looking statements that involve a number of
risks and uncertainties. The Company's actual liquidity needs, capital resources
and results may differ materially from the discussion set forth in the
forward-looking statements. For a discussion of important factors that may cause
the actual results, performance or achievements of the Company to be materially
different from those expressed or implied by the forward-looking statements, see
"Business -- Risk Factors" in the Company's Annual Report on Form 10-K for the
fiscal year ended December 31, 1997. In light of such risks and uncertainties,
there can be no assurance that the forward-looking information contained in this
item will in fact transpire.
 
THREE AND NINE MONTHS ENDED SEPTEMBER 30, 1998 COMPARED WITH THE THREE AND NINE
MONTHS ENDED SEPTEMBER 30, 1997
 
     On June 3, 1998, the Company completed a merger of a Company subsidiary
with Eclipse Telecommunications, Inc., formerly Network Long Distance, Inc.
("Eclipse"), by exchanging approximately 4.05 million shares of its common stock
for all of the outstanding common stock of Eclipse. Each share of Eclipse was
exchanged for .2998 shares of common stock of the Company. In addition,
outstanding Eclipse stock options were converted at the same exchange factor
into options to purchase shares of the Company's common stock. The merger
constituted a tax-free reorganization and has been accounted for as a pooling of
interests. Accordingly, all prior period consolidated financial statements have
been restated to include the combined results of operations, financial position,
and cash flows of Eclipse as though it had always been a part of the Company.
 
     Net operating revenue for the third quarter of 1998 increased by 35.4% over
the third quarter of 1997 due in part to a $23.6 million increase in private
line revenue. The private line increase reflected the impact of the Company's
larger network and associated capacity available for lease in 1998. A
significant portion of this improvement was from a large capacity contract with
one Internet Service Provider ("ISP"). Net operating revenue in the third
quarter of 1998 was also affected by a $15.9 million increase in switched long
distance revenue due mainly to a 21.9% increase in wholesale billable minutes of
use ("MOU"). A major portion of this increase was due to services provided to a
debit card provider during the third quarter. The debit card provider has been a
customer for switched long distance services for several years and became a
significant customer in the third quarter due to the success of its sale of
debit cards. In November 1998, the Company resolved certain billing and payment
disputes with the customer and such resolution is expected to result in further
significant increases in this customer's MOUs. In light of the dramatic increase
in MOUs from this customer, the Company agreed (i) to credit certain of the
customer's third quarter billings (which amount was adequately reserved at
September 30, 1998) primarily to reflect reduced rates for increased volume;
(ii) to decrease its current billing rates to reflect the customer's continuing
increase in MOUs and (iii) to accept a secured note for approximately $16
million payable at the rate of $250,000 per week for prior services. Net
operating revenue in the third quarter of 1998 also included $9.0 million of
other revenue relating to cash received from the sale of an option in certain
rights in fibers jointly owned with another carrier. Operating revenue for the
first nine months of 1998 increased 39.5% over the first nine months of 1997.
That increase of $141.3 million was mainly due to an increase in switched long
distance revenue of $83.8 million. The improvement in switched long distance
revenue for the nine months came from a 33.9% increase in wholesale MOU as well
as the increase in the number of retail customers. The private line revenue
increase was due to increased demand for capacity, including the large capacity
agreement with the ISP, and the availability of additional capacity on the
Company's network in 1998.
 
     Cost of services primarily reflects access charges paid to Local Exchange
Carriers ("LEC's") and transmission lease payments (monetary and nonmonetary) to
other carriers. These costs for the quarter and year to date increased 8.9% and
17.6% respectively over the comparable 1997 periods. Transmission lease expense
for the quarter increased 10.6% over the 1997 quarter related to additional
transmission lease expense paid to support the Company's private line and
switched long distance businesses in advance of expanding the network's
capacity. The increase in the transmission lease expense was mitigated by the
Company transferring off-net traffic to its expanding fiber network, and by a
greater proportion of new revenue being carried on the Company's network. The
increase in access costs was caused by additional wholesale MOU's overflowed to
                                       12
<PAGE>   13
 
other carriers and access charges paid to LEC's associated with the additional
revenue. The increase in access costs was mitigated by FCC-mandated reductions
in unitary (per minute) access costs, net of increased costs related to new
tandem trunking charges which were implemented July 1, 1998 and by improved
management of costs related to traffic mix and overflow traffic.
 
     The improved revenue and smaller increases in cost of services resulted in
gross margin in the third quarter of 1998 of 40.6% compared to 26.2% in the same
period in 1997. On a year-to-date basis, the gross margin increased to 34.7% in
1998 compared to 22.5% during the 1997 period.
 
     Operating and administrative costs in the quarter increased $12.0 million
to $40.1 million, representing 21.6% of revenue versus 20.5% in the prior year's
third quarter. The increase was due primarily to additional headcount and other
operating costs related to the expanded fiber network and higher sales and
administration costs related to expanding the Company's retail sales force. The
Company intends to continue to expand the retail sales force and the network;
therefore, operating and administration expenses may continue to increase in
total and as a percentage of revenue.
 
     Depreciation and amortization increased 52.2% from last year's third
quarter and 60.5% for the nine month period, due to an increase in depreciable
assets relating to completed segments of the Company's expanding network and
capacity available on the network. Depreciation and amortization are expected to
continue to rise because of increased spending on assets to add to the network's
capacity.
 
     In connection with the Eclipse merger, the Company recorded merger-related
costs of $8.1 million during 1998 related to the execution of the transaction,
the write-off of duplicate assets, and the integration of the functions of the
two companies. These costs consist of (i) professional services including legal,
investment banking and accounting associated with the transaction of $3.5
million; (ii) severance costs of $0.6 million from the termination of
approximately 125 duplicate administrative and sales positions; (iii) costs of
$1.7 million to terminate leases for duplicate office space; (iv) the write off
of $1.8 million in duplicate equipment and software; and (v) costs of $0.5
million incurred during the second and third quarters to integrate the business
processes. The Company expects to incur $2.0 to $4.0 million in additional
integration costs during the remainder of 1998. Merger-related costs incurred
during 1997 relate to earlier acquisitions by Eclipse.
 
     Interest income increased 50.7% for the first three quarters over the prior
year's period due to the additional funds available in 1998 from the issuance of
the 6 3/4% Convertible Preferred Stock ("6 3/4% Convertible Preferred Stock")
and the $450 million of 9% Senior Subordinated Notes Due 2008 (the "9% Senior
Subordinated Notes") in March and April 1998. Interest income in the third
quarter of 1998 was relatively unchanged from the third quarter of 1997 as a
result of the use of cash for capital expenditures in 1998.
 
     Interest expense decreased by 5.6% from last year's third quarter to $7.6
million this quarter. For the first three quarters of 1998, interest expense
decreased 7.0% to $22.4 million from the comparable period in 1997. Interest
expense for both the quarter and nine months decreased due to additional
capitalized interest relating to increased capital expenditures in 1998.
 
     Equity in net losses of unconsolidated subsidiaries for the third quarter
increased $1.0 million from 1997 to $8.3 million in 1998. For the nine-month
period, equity losses increased $16.7 million to $30.3 million in 1998. The
increased losses for the quarter relate to the Company's 20% interest in Unidial
Communications Services, LLC a retail long distance joint venture and the
Company's 40% interest in Storm, a European joint venture. Neither of these
investments were in place during the first nine months of 1997. Losses from the
Company's indirect interest in Marca-Tel S.A. de C. V. ("Marca-Tel"), a Mexican
joint venture which is constructing a fiber network in Mexico and has been
operating since the first quarter of 1997, declined year-over-year for the third
quarter due to the increased level of revenue generated by Marca-Tel. Beginning
in June 1998 the Company's investment in PSINet, Inc. ("PSINet"), an internet
service provider, was reported on a cost basis due to a reduced level of
ownership; therefore, no equity results were recorded during the quarter for
this investment. The year-over-year increase in equity losses is due to losses
from all four unconsolidated subsidiaries. Currently, the Company's investment
balance in Marca-Tel is negative and Marca-Tel required minimal funding by the
Company in the current quarter. At the present time, the Company does not
anticipate significant additional funding to Progress International LLC
("Progress
 
                                       13
<PAGE>   14
 
International") for investment in Marca-Tel until the regulatory and market
conditions improve in Mexico. The Company is not obligated to continue to fund
Progress International. The Company and the other direct and indirect owners of
Marca-Tel are currently in discussions with investment bankers to obtain
additional financing for Marca-Tel; however, with the current depressed
financing market for companies in emerging markets, it is unlikely that public
financing will be available in the near term. Marca-Tel received a notice of
default from its major source of current financing in October 1998. Negotiations
are in process and the outcome of those discussions is unclear at this time. The
default could result in the foreclosure of a third party's security interest in
Progress International's interest in Marca-Tel. If that were to occur, the
Company's indirect interest in Marca-Tel could be diluted or lost entirely.
 
     Income tax expense increased to $1.6 million in the current period from
$0.7 million in the prior year's third quarter. For the first nine months of
1998, income tax expense increased to $8.3 million from $.5 million in the first
nine months of 1997. These increases are primarily due to state income taxes
related to the sale of indefeasible rights to use capacity or fibers on the
Company's network and the other operating revenue of $9.0 million in the third
quarter 1998. The deferred tax assets relating to the Company's pretax operating
losses have been fully reserved due to the uncertainty of their realization.
 
     In connection with the sale of $450 million of 9% Senior Subordinated
Notes, the Company completed a tender offer to purchase for cash its outstanding
12 1/2% Senior Notes Due 2005. The Company recorded an after-tax extraordinary
loss of $69.6 million relating to the redemption of $284.2 million of the
12 1/2% Senior Notes Due 2005.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Historically, private line operations provided adequate cash flow to meet
the Company's operational needs. The Company is financing the expansion of its
network through the issuance of debt and equity securities.
 
     Cash provided by operating activities was $127.9 million for the nine
months ended September 30, 1998 compared to $21.7 million in the comparable
period of 1997. This change occurred primarily because of payments received
relating to indefeasible right to use ("IRU") agreements, other operating
revenue, and improved operations in both the private line and switched long
distance businesses.
 
     Cash used in investing activities for the nine months ended September 30,
1998 was $384.2 million compared to $171.7 million for the comparable period of
1997. The increase is primarily due to an increase in capital expenditures
compared to the 1997 period related to building the Company's network. Funding
from escrow accounts related to the 12 1/2% Senior Notes Due 2005 provided a net
of $51.4 million during the first nine months of 1997. There was no such
activity during 1998. The Company expects that its capital expenditures will
continue to require a significant amount of cash through the end of fiscal year
1999 and thereafter. The remaining increase in cash used for investing
activities was due to funding certain acquisitions and investments in
unconsolidated subsidiaries.
 
     Cash provided by financing activities decreased $128.1 million as net
proceeds from debt and equity financing increased by $212.8 million but were
more than offset by an increase of $336.8 million in debt repayments principally
related to the Company's 12 1/2% Senior Notes Due 2005.
 
     As of September 30, 1998, the Company had $141.7 million in cash. On
October 28, 1998, the Company entered into a $600 million senior secured credit
facility with a syndicate of commercial banks. The Company received funding of
$200 million, net of $4.2 million of transaction costs. The facility consists of
a $150 million revolving facility, a $200 million term loan facility, and an
uncommitted special purpose loan facility of $250 million. The Company must
comply with various financial and other covenants on an ongoing basis in
addition to meeting the covenants on a pro forma basis prior to drawing
additional amounts under the credit facility. Loans outstanding under the credit
facility bear interest at either LIBOR or the lead commercial bank's prime rate
plus applicable margins.
 
     The Company expects that its primary sources for cash over the next twelve
months will be cash on hand, cash generated by operations, proceeds from the
credit facility discussed above, proceeds of fiber use sales and the proceeds
from any additional debt, vendor and working capital financing the Company may
seek. The
 
                                       14
<PAGE>   15
 
Company is in discussions with various investment bankers, vendors and lending
institutions regarding substantial additional debt financing for the remainder
of 1998 and beyond. The Company seeks to obtain sufficient funding from these
sources plus cash receipts from fiber use sales for the following major uses of
cash: (i) the network expansion and other capital expenditures; (ii) debt
service; (iii) lease payments; (iv) increasing the retail and internet sales
forces; (v) funding joint ventures; (vi) working capital, and (vii) dividends on
preferred stock. Capital spending in 1998 is projected to be over $525.0
million, of which $362.7 million has been spent through September 30, 1998.
After 1998, capital expenditures are expected to continue to be substantial.
There can be no assurance that the Company will be successful in obtaining the
necessary financing to meet its needs. A failure to raise cash would delay or
prevent capital expenditures including the construction of the network
expansion. The foregoing capital expenditure and cash requirements for 1998 do
not take into account any acquisitions that may subsequently occur.
 
     The Company is required to make semi-annual interest payments on its 9%
Senior Subordinated Notes and the remaining 12 1/2% Senior Notes. The Company is
also required to make principal payments of approximately $3.7 million on other
debt in 1998. The Company is required (except in certain circumstances when the
dividend payment can be a payment in kind) to pay quarterly cash dividends on
the 7 1/4% Convertible Preferred Stock at an annual rate of 7 1/4%, on the
6 3/4% Convertible Preferred Stock at an annual rate of 6 3/4% and on the Junior
Exchangeable Preferred Stock due 2009 (the "12 1/2% Exchangeable Preferred
Stock") at an annual rate of 12 1/2%. The Company anticipates that such debt and
equity service payments during 1998 will be made from cash on hand, except for
the dividends on the 12 1/2% Exchangeable Preferred Stock which are anticipated
to be paid in kind with stock dividends.
 
     The Company is required to make minimum annual lease payments for
facilities, equipment and transmission capacity used in its operations. In the
remainder of 1998, 1999, and 2000, the Company is currently required to make
payments of approximately $1.8 million, $7.0 million and $5.9 million,
respectively, on capital leases and $12.7 million, $19.8 million and $8.8
million, respectively, on operating leases. The Company expects to incur
additional operating and capital lease costs in connection with the expansion of
its network and its retail and Internet operations. Additionally, in connection
with its network expansion, the Company from time to time enters into various
construction and installation agreements with contractors.
 
     The forward-looking statements set forth above with respect to the
estimated cash requirements relating to capital expenditures, the Company's
ability to meet such cash requirements and the Company's ability to service its
debt are based on certain assumptions as to future events. Important
assumptions, which if not met, could adversely affect the Company's ability to
achieve satisfactory results include that: (i) there will be no significant
delays or cost overruns with respect to the network expansion; (ii) the
Company's contractors and partners in cost-saving arrangements will perform
their obligations; (iii) rights-of-way can be obtained in a timely,
cost-effective basis; (iv) the routes of the network expansion are substantially
completed on schedule; (v) the Company will continue to increase traffic on its
network; and (vi) the Company can obtain vendor or additional debt financing.
 
YEAR 2000 RISKS
 
     The Year 2000 issue is the result of computer software programs being coded
to use two digits rather than four to define the year. It is possible that some
of the Company's existing computer programs that have date-sensitive coding may
recognize a date using "00" as the year 1900 rather than the year 2000. This
could result in system failures or miscalculations causing disruption of
operations, which could have a material adverse effect on the Company's ability
to conduct business after January 1, 2000, including the inability of the
Company to provide telecommunications services to its customers or to accurately
invoice customers or collect payments.
 
     Substantially all of the Company's network was built in the last three
years. As a result, the Company believes that it does not have a significant
investment in legacy systems having substantial Year 2000 exposure. However, the
Company has established a project team to identify, evaluate and address any
existing Year 2000 issues. This Year 2000 effort covers the Company's fiber
optic network and supporting infrastructure related to providing switched,
private line and data telecommunications services, and other operational and
financial information technology ("IT") systems and applications. Also included
in this effort are various
 
                                       15
<PAGE>   16
 
other systems such as building operations and individual personal computers used
by Company personnel. The project team is reviewing the status of the Year 2000
compliance effort of key suppliers and other business partners, and is
developing business continuity plans related to Year 2000 issues. While the Year
2000 project team is evaluating all potentially non-compliant systems, the Year
2000 effort is structured to give priority to those systems identified as
"mission critical".
 
     The project team has identified the following principal phases of the
project: a) assessment and planning, b) remediation, c) testing, and d)
contingency planning. The assessment phase is expected to be substantially
complete by December 31, 1998. The Company has established a target date of
March 31, 1999, for remediation of mission critical systems. Of the applications
identified as critical, many have already been remediated and are being tested.
Testing is expected to be completed by September 30, 1999 for all applications.
In addition, all new components being purchased as part of the Company's ongoing
network and IT infrastructure expansion are being evaluated to ensure
compliance.
 
     There can be no assurances that third parties, including customers,
suppliers, and other business partners, will convert their critical systems and
processes in a timely manner. Such failure by any of these parties could disrupt
the Company's business. Therefore, in addition to evaluating its own internal
systems, the Company is in the process of evaluating and documenting the status
of Year 2000 compliance efforts by its key suppliers.
 
     The Company currently projects that it will incur and expense approximately
$2 million through the end of 2000 in connection with the Year 2000 remediation
project, of which less than $0.5 million has been incurred and expensed as of
September 30, 1998. Such amounts are exclusive of amounts which were already
anticipated to be spent on new hardware and software purchases resulting from
the expansion of the Company's network and other business operations. The
Company believes that a significant portion of the Year 2000 expenses will not
be incremental costs, but rather will represent the redeployment of existing IT
resources. This redeployment may cause delays in making other IT or network
upgrades or enhancements; however, the delays are not expected to have a
material effect on the Company's operations.
 
     As part of its Year 2000 initiative, the Company is evaluating scenarios
that may occur as a result of the century change and anticipates developing
contingency and business continuity plans tailored for Year 2000-related
problems by December 31, 1998. These plans are expected to provide for key
operational back-up, recovery and restoration alternatives.
 
     The above information is based on estimates, which were derived using
numerous assumptions of future events, including the availability and future
costs of certain technological and other resources, third party modification
actions and other factors. Given the complexity of these issues and other
unidentified risks, actual results may vary materially from those anticipated
and discussed above. Specific factors that might cause such differences include,
among others, the availability and cost of personnel trained in this area, the
ability to locate and correct all affected computer code, the timing and success
of remedial efforts of our third party suppliers and similar uncertainties.

     In August 1998, the Corporation furnished an Information Statement to
stockholders of the Corporation pursuant to Rule 14c-2 under the Securities
Exchange Act of 1934 (the "Exchange Act"), in connection with an amendment (the
"Amendment") to the Restated Certificate of Incorporation, as amended (the
"Restated Certificate") of the Corporation to (i) provide for an increase in the
authorized number of shares of the Corporation's common stock (the "Common
Stock"); (ii) effect a two-for-one stock split of the Common Stock; (iii) create
a new class of preferred stock; and (iv) eliminate from the Restated Certificate
all matters therein with respect to the Corporation's 10% Senior Series 1
Cumulative Redeemable Preferred Stock and 10% Junior Series 3 Redeemable
Preferred Stock. The Amendment was approved by the Board and a majority of the
outstanding shares of Common Stock by written consent in lieu of a meeting
pursuant to Section 228(a) of the Delaware General Corporation Law (the "DGCL").
The Information Statement also served as notice to stockholders of an action
taken by less than unanimous written consent as required by Section 228(d) of
the DGCL. The Information Statement was mailed on or about August 14, 1998 to
persons who were stockholders of record on July 22, 1998.
 
     On September 2, 1998, the Corporation announced that it was postponing the
filing of a Certificate of Amendment to the Restated Certificate which would
effectuate the Amendment. The Corporation's Board of Directors determined that
under current market conditions, it would not be in the best interests of the
stockholders of the Corporation to file the Certificate of Amendment to
effectuate the Amendment.
 
     In September 1998, the Corporation also furnished an Information Statement
to stockholders of the Corporation pursuant to Rule 14c-2 of the Exchange Act in
connection with the Corporation's 1998 Stock Plan (the "1998 Plan"). The 1998
Plan was approved by the Board and by a majority of the outstanding shares of
Common Stock by written consent in lieu of a meeting pursuant to Section 228(a)
of the DGCL. The adoption and approval of the 1998 Plan became effective on
October 7, 1998 which, pursuant to Rule 14c-2 under the Exchange Act, was a date
at least 20 days following the date on which the Information Statement was
mailed to the stockholders of the Corporation. The Information Statement also
served as notice to stockholders of an action taken by less than unanimous
written consent as required by Section 228(d) of the DGCL. The Information
Statement was mailed on or about September 14, 1998 to persons who were
stockholders of record on August 5, 1998.
 
ITEM 5. OTHER INFORMATION
 
     On September 2, 1998, the Corporation announced that it was postponing its
previously announced two-for-one stock split, the increase in its authorized
shares of common stock and the creation of a new class of preferred stock.
 
     The two-for-one stock split and adjustments to the capital structure had a
record date of (and were to be effected by the filing of the Certificate of
Amendment as described above on) September 4, 1998. The Corporation's Board of
Directors has determined that under current market conditions, it would not be
in the best interests of stockholders to file the Certificate of Amendment which
would effectuate the two-for-one stock split previously approved by its
directors and its stockholders. As a result, the number of authorized, issued
and outstanding shares of the Corporation, and the holdings of each individual
stockholder, remain unchanged at the present time.

                              RESTATED CERTIFICATE
                                       OF
                           INCORPORATION, AS AMENDED


         Fiber Optic Communications, Inc., a corporation organized and existing
under the laws of the State of Delaware, hereby certifies as follows:

         1.      The name of this corporation is Fiber Optic Communications,
Inc.  Fiber Optic Communications, Inc. was originally incorporated under the
same name.  The original Certificate of Incorporation of this corporation was
filed with the Secretary of State of the State of Delaware on July 27, 1992.

         2.      Pursuant to Sections 242 and 245 of the General Corporation
Law of the State of Delaware, this Restated Certificate of Incorporation has
been duly adopted and restates, integrates and further amends the provisions of
the Certificate of Incorporation of this corporation.

         3.      This Restated Certificate of Incorporation was duly consented
to, and adopted by, the holders of (i) a majority of the outstanding shares of
common stock, par value $.01 per share, of the Corporation and 10% Senior
Series 1 Cumulative Redeemable Preferred Stock, par value $.01 per share, of
this corporation ("Series 1 Preferred Stock"), consenting together as a class
and by (ii) over three-fourths (3/4s) of the outstanding shares of Series 1
Preferred Stock, acting without a meeting by unanimous written consent pursuant
to Section 228 of the General Corporation Law of the State of Delaware.

         4.      The text of the Restated Certificate of Incorporation as
heretofore amended or supplemented is hereby restated and further amended to
read in its entirety as follows:

         FIRST:  The name of this corporation (the "Corporation") is "IXC
Communications, Inc."

         SECOND: The address of the registered office of the Corporation in the
State of Delaware is Corporation Trust Center, 1209 Orange Street, in the City
of Wilmington, County of New Castle, Delaware 19801.  The name of its
registered agent at such address is The Corporation Trust Company.

         THIRD:  The purpose of the Corporation is to engage in any lawful act
or activity for which a corporation may now or hereafter be organized under the
General Corporation Law of the State of Delaware as set forth in Title 8 of the
Delaware Code.

         FOURTH: The total number of shares of stock which the Corporation
shall have authority to issue is one hundred and three million (103,000,000)
consisting of (i) one

<PAGE>   2
hundred million (100,000,000) shares of common stock, par value $.01 per share,
and (ii) three million (3,000,000) shares of preferred stock, par value $.01
per share.  The preferred stock may be issued at any time, and from time to
time, in one or more series pursuant hereto or to a resolution or resolutions
providing for such issue duly adopted by the board of directors (the "Board")
of the Corporation (authority to do so being hereby expressly vested in the
Board), and such resolution or resolutions shall also set forth the voting
powers, full or limited, or none, of each such series of preferred stock and
shall fix the designations, preferences and relative, participating, optional
or other special rights and qualifications, limitations or restrictions of each
such series of preferred stock.

                 Upon the filing of this Second Amendment to Restated
Certificate of Incorporation which amends Article FOURTH to read as set forth
above, and without any further action on the part of the holders thereof, each
issued and outstanding share of common stock will be reclassified and changed 
into 0.8083 shares of common stock.

         FIFTH:  The business and affairs of the Corporation shall be managed
by and under the direction of the Board.  The exact number of directors of the
Corporation shall be fixed by or in the manner provided in the Bylaws of the
Corporation (the "Bylaws").

         SIXTH:  In furtherance and not in limitation of the powers conferred
by statute, the Board is expressly authorized:

         (a)     to adopt, repeal, rescind, alter or amend in any respect the
Bylaws, and to confer in the Bylaws powers and authorities upon the directors
of the Corporation in addition to the powers and authorities expressly
conferred upon them by statute;

         (b)     from time to time to set apart out of any funds or assets of
the Corporation available for dividends an amount or amounts to be reserved as
working capital or for any other lawful purpose and to abolish any reserve so
created and to determine whether any, and, if any, what part, of the surplus of
the Corporation or its net profits applicable to dividends shall be declared in
dividends and paid to its stockholders, and all rights of the holders of stock
of the Corporation in respect of dividends shall be subject to the power of the
Board so to do;

         (c)     subject to the laws of the State of Delaware, from time to
time to sell, lease or otherwise dispose of any part or parts of the properties
of the Corporation and to cease to conduct the business connected therewith or
again to resume the same, as it may deem best; and

         (d)     in addition to the powers and authorities hereinbefore and by
the laws of the State of Delaware conferred upon the Board, to execute all such
powers and to do all acts and things as may be exercised or done by the
Corporation; subject, nevertheless, to the express provisions of such laws, of
the Restated Certificate of Incorporation of the Corporation and its Bylaws.





                                       2


<PAGE>   3
         SEVENTH:  Meetings of stockholders of the Corporation may be held 
within or without the State of Delaware, as the Bylaws provide.  The books 
of the Corporation may be kept (subject to any provision of applicable law)
outside the State of Delaware at such place or places as may be designated 
from time to time by the Board or in the Bylaws.

         EIGHTH:  The Corporation reserves the right to adopt, repeal, rescind,
alter or amend in any respect any provision contained in this Restated
Certificate of Incorporation in the manner now or hereafter prescribed by
applicable laws, and all rights conferred on stockholders herein are granted
subject to this reservation.

         NINTH:  The Corporation is to have perpetual existence.

         TENTH:  A director of this Corporation shall not be personally liable
to the Corporation or its stockholder for monetary damages for breach of
fiduciary duty as a director, except for liability (i) for any breach of the
director's duty of loyalty to the Corporation or its stockholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or
a knowing violation of law, (iii) under Section 174 of the Delaware General
Corporation Law, as the same exists or hereafter may be amended, or (iv) for
any transaction from which the director derived an improper personal benefit.
If the Delaware General Corporation Law hereafter is amended to authorize the
further elimination or limitation of the liability of directors, then the
liability of a director of the Corporation, in addition to the limitation on
personal liability provided herein, shall be limited to the fullest extent
permitted by the amended Delaware Corporation Law.  No amendment to or repeal
of this Article Tenth shall apply to or have any effect on the liability or
alleged liability of any director of the Corporation for or with respect to any
acts or omissions of such director occurring prior to such amendment or repeal.

         ELEVENTH:

         A.      Designation of Two Series of Preferred Stock.  There are
hereby provided two series of preferred stock designated and to be known as

                 3.       "Preferred Stock" shall mean the preferred stock,

         D.      Rights, Preferences, Privileges and Restrictions.  The voting
powers and relative rights, preferences, restrictions and other mattes relating
to the Series Preferred Stock are as follows:

                 1.       Dividends.

                          (a)     The holders of shares of Series 1 Preferred
Stock then outstanding shall be entitled to receive, prior to the payment of any
dividend on any other Preferred Stock of the Corporation or the Common Stock of
the Corporation, when, as and if declared by the Board, out of funds legally
available for the payment of dividends, cumulative dividends in an annual amount
equal to $100 per share, plus an amount determined by applying a 10% annual
rate, compounded annually, to any accrued but unpaid dividend amount from the
last day of the period when such dividend accrues to the actual date of payment
of such dividend, and no more.  The holders of shares of Series 3 Preferred
Stock then outstanding shall be entitled to receive, prior to the payment of any
dividend on any other Preferred Stock of the Corporation (other than the Series
1 Preferred Stock) or the Common Stock of the Corporation, when as and if
declared by the Board, out of funds legally available for the payment of
dividends, cumulative dividends in an annual amount equal to $100 per share,
plus an amount determined by applying a 10% annual rate, compounded annually, to
any accrued but unpaid dividend amount from the last day of the period when such
dividend accrues to the actual date of payment of such dividend, and no more;
provided, however, that (i) the Corporation may pay dividends on the
Corporation's 7-1/4% Junior Convertible Preferred Stock Due 2007 ("Convertible
Preferred Stock") with additional shares of Convertible Preferred Stock and (ii)
the Corporation may pay dividends on the Corporation's 12-1/2% Junior
Exchangeable Preferred Stock Due 2009 (the "Initial Exchangeable Preferred
Stock") and 12-1/2% Series B Junior Exchangeable Preferred Stock Due 2009 (the
"Series B Stock") with additional shares of Initial Exchangeable Preferred Stock
and Series B Stock, respectively.  Such dividends on the outstanding shares of
Series Preferred Stock shall be payable on such date as the Board may from time
to time determine (each such date being a "dividend payment date").  The Board
may fix a record date for the determination of holders of shares of Series
Preferred Stock entitled to receive payment of a dividend declared thereon,
which record date shall not be more than sixty (60) days prior to the date fixed
for





                                       4
<PAGE>   5
the payment thereof.  Each such annual dividend shall be fully cumulative and
shall accrue from day to day (whether or not declared) from the first day of
each period in which such dividend may be payable as herein provided, except
that the first annual dividend with respect to each share of Series Preferred
Stock shall accrue from the Original Issue Date of such share or such other
date as determined by the Board, except that dividends with respect to each
share of Series 3 Preferred Stock shall accrue from August 14, 1992.
Dividends, when, as and if declared, shall be payable in cash.

                          (b)     The holder of each outstanding fractional
share of Series Preferred Stock shall be entitled to a ratably proportionate
amount of all dividends accruing with respect to each outstanding share of
Series Preferred Stock with the same Original Issue Date and all such dividends
with respect to each such outstanding fractional share shall be fully
cumulative and shall accrue (whether or not declared) and shall be payable in
the same manner and at such times as provided for in Section 1(a).

                          (c)     All dividends paid with respect to the
outstanding shares of Series Preferred Stock pursuant to Section 1(a) shall be
paid pro rata to the holders of each class entitled thereto.  Each Series 1
Preferred Stock holder's pro rata share of such dividends shall be calculated
by multiplying the total dividends to be paid by the percentage of (i) the
aggregate accrued but unpaid dividends to the date such payment is made on all
issued and outstanding shares of Series 1 Preferred Stock represented by (ii)
the aggregate accrued but unpaid dividends to the date such payment is made on
all shares (including fractional shares) of Series 1 Preferred Stock held by
such holder, and no more.  Each Series 3 Preferred Stock holder's pro rata
share of such dividends shall be calculated by multiplying the total dividends
to be paid by the percentage of (i) the aggregate accrued but unpaid dividends
to the date such payment is made on all issued and outstanding shares of Series
3 Preferred Stock represented by (ii) the aggregate accrued but unpaid
dividends to the date such payment is made on all shares (including fractional
shares) of Series 3 Preferred Stock held by such holder, and no more.

                 2.       Liquidation Rights of Series Preferred Stock:

                          (a)     In the event of any liquidation, dissolution
or winding up of the Corporation, whether voluntary or involuntary, the holders
of outstanding shares of Series Preferred Stock shall be entitled to be paid
out of the assets of the Corporation available for distribution to its
stockholders, whether such assets are capital, surplus, or earnings, before any
payment or declaration and setting apart for payment of any amount shall be
made in respect of the outstanding shares of any other Preferred Stock of the
Corporation or Common Stock of the Corporation, an amount equal to $1,000 per
share of Series Preferred Stock then outstanding, plus all accrued but unpaid
dividends thereon to the date such payment is actually made, and no more.  If
upon any liquidation, dissolution or winding up of the Corporation, whether
voluntary or involuntary, the assets to be distributed among the holders of the
outstanding shares of Series Preferred Stock shall be insufficient to permit
the payment to such stockholders of the full preferential amounts set forth
above, then





                                       5
<PAGE>   6
the entire assets of the Corporation to be distributed shall be distributed (i)
first, ratably among the holders of outstanding shares of Series 1 Preferred
Stock based on the full preferential amounts for the number of outstanding
shares of Series 1 Preferred Stock held by each holder and (ii) second, ratably
among the holders of outstanding shares of Series 3 Preferred Stock based on
the full preferential amounts for the number of outstanding shares of Series 3
Preferred Stock held by each holder.  The Corporation will mail written notice
of such liquidation, dissolution or winding up, not less than sixty (60) days
prior to the payment date stated therein, to each record holder of Series
Preferred Stock.

                          (b)     A consolidation or merger of the Corporation
with or into any other corporation or corporations or a sale of all or
substantially all of the assets of the Corporation shall not be deemed to be a
liquidation, dissolution, or winding up of the Corporation as those terms are
used in this Section 2 unless such consolidation, merger or sale shall be in
connection with a dissolution or winding up of the Corporation.

                          (c)     The payment of preferential amounts pursuant
to this Section 2 with respect to each outstanding fractional share of Series 1
Preferred Stock shall be equal to a ratably proportionate amount of the
preferential amount payable with respect to each outstanding share of Series 1
Preferred Stock with the same Original Issue Date.  The payment of preferential
amounts pursuant to this Section 2 with respect to each outstanding fractional
share of Series 3 Preferred Stock shall be equal to the ratably proportionate
amount of the preferential amount payable with respect to each outstanding
share of Series 3 Preferred Stock with the same Original Issue Date.

                 3.       Voluntary Redemption by the Corporation.

                          (a)     The Corporation, at the option of the Board,
may at any time or from time to time redeem the outstanding shares of Series 1
Preferred Stock in whole or in part from any source of funds legally available
therefor.  The Corporation, at the option of the Board, may at any time or from
time to time redeem the outstanding shares of Series 3 Preferred Stock in whole
or in part from any source of funds legally available therefor, provided that
there shall then be no outstanding shares of Series 1 Preferred Stock.

                          (b)     The redemption price for each outstanding
share of Series Preferred Stock shall be equal to $1,000 plus an amount equal
to any accrued and unpaid dividends on such share through the Redemption Date
(as defined below), whether or not declared (the "Redemption Price").

                          (c)     In the event of a redemption of only a part
of the outstanding shares of a class of Series Preferred Stock, the Corporation
shall effect such redemption pro rata according to the number of shares held by
each holder of outstanding shares of such class of Series Preferred Stock.





                                       6
<PAGE>   7
                          (d)     At least ten (10) days and not more than
sixty (60) days prior to the date fixed for any redemption of shares of a class
of Series Preferred Stock (the "Redemption Date"), written notice (the
"Redemption Notice," and the class of Series Preferred Stock referenced in such
Redemption Notice shall be referred to herein as the "Redeemed Stock") shall be
sent, by registered mail, to each holder of record of the outstanding shares of
Redeemed Stock at his or her mailing address last shown on the records of the
Corporation.  Any notice which is mailed in the manner herein provided shall be
conclusively presumed to have been duly given, whether or not the holder
received the notice, and failure duly to give the notice by mail, or any defect
in the notice, to any holder of shares of such class of Series Preferred Stock
designated for redemption shall not affect the validity of the proceedings for
the redemption of any other shares of such class of Series Preferred Stock.
The Redemption Notice shall state:

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

                                  (ii)     the number of outstanding shares of
Redeemed Stock held by the holder which the Corporation intends to redeem;

                                  (iii)    the Redemption Date and the
Redemption Price;

                                  (iv)     that from and after the Redemption
Date, dividends shall cease to accrue; and

                                  (v)      that the holder is to surrender to
the Corporation, in the manner and at the place designated, the certificate or
certificates representing the outstanding shares of Redeemed Stock to be
redeemed.

                          (e)     On or before the Redemption Date, each holder
of outstanding shares of Redeemed Stock shall surrender the certificate or
certificates representing such shares to the Corporation, in the manner and at
the place designated in the Redemption Notice, and thereupon the Redemption
Price for such shares shall be payable to the order of the person whose name
appears on such certificate or certificates as the owner thereof, and each
surrendered certificate shall be cancelled and retired.  In the event less than
all of the shares represented by any such certificate or certificates are
redeemed, a new certificate or certificates shall be issued representing the
unredeemed shares.  All shares of the class of Series Preferred Stock called
for redemption will cease to accrue dividends as of the Redemption Date.  After
the Redemption Date, holders of such class of Series Preferred Stock shall no
longer be treated as stockholders of the Corporation with respect to the shares
of Series Preferred Stock being redeemed, except with respect to the right to
receive the Redemption Price, without interest, upon the surrender of their
respective certificates.





                                       7
<PAGE>   8
                        (f)      The Corporation may, at its option, on or 
prior to the Redemption Date, deposit with its transfer agent or other 
redemption agent selected by the Board of Directors of the Corporation, as a 
trust fund, a sum sufficient to redeem the shares called for redemption, with 
irrevocable instructions and authority to such transfer agent or other 
redemption agent to give or complete the Redemption Notice and to pay to the 
respective holders of such shares, as evidenced by a list of such holders 
certified by an officer of the Corporation, the Redemption Price upon 
surrender of their respective share certificates.  Such deposit shall be 
deemed to constitute full payment of such shares to their holders.  In case 
the holders of any shares shall not, within five (5) years after such deposit,
claim the amount deposited for redemption thereof, such transfer agent or 
other redemption agent shall, upon demand, pay over to the Corporation the 
balance of such amount so deposited and shall thereupon be relieved of all 
responsibility to the holders thereof.  Any interest accrued on any funds so 
deposited shall belong to the Corporation, and shall be paid to it from time 
to time on demand.

                        (g)      All shares of Series 1 Preferred Stock which 
shall have been redeemed pursuant to this Section 3 shall thereupon be 
restored to the status of authorized but unissued shares of Series 1 Preferred
Stock.

                        (h)      All shares of Series 3 Preferred Stock which 
shall have been redeemed pursuant to this Section 3 shall thereupon be 
restored to the status of authorized but unissued shares of Series 3 Preferred
Stock.

         4.      Voting Rights.  Except as otherwise provided herein or by the
General Corporation Law of the State of Delaware, holders of outstanding shares
of Series 1 Preferred Stock shall have no voting rights.  At all meetings of
the stockholders of the Corporation and in the case of any actions of
stockholders in lieu of a meeting, each share of Series 3 Preferred Stock shall
entitle the holder thereof to one vote.  Except as otherwise provided herein or
by the General Corporation Law of the State of Delaware, the holders of Common
Stock and Series 3 Preferred Stock shall vote together as a single class, and
neither the Common Stock nor Series 3 Preferred Stock shall be entitled to vote
as a separate class on any matter to be voted on by shareholders of the
Corporation, except that the holders of the Series 3 Preferred Stock shall be
entitled to vote as a separate class to elect one member of the Board of
Directors of the Corporation.

         5.      Restrictions and Limitations.  Except as otherwise provided by
the General Corporation Law of the State of Delaware, no amendment to this
Restated Certificate of Incorporation shall be made by the Corporation which
would change any of the terms, rights, preferences, privileges or restrictions
provided herein so as to affect adversely any shares of Series Preferred Stock
without the prior written consent of the holders of at least a majority of each
of the Series 1 Preferred Stock and the Series 3 Preferred Stock entitled to
vote thereon and outstanding at the time such action is taken; provided that no
amendment will change (i) the rate or times at which or the manner in which
dividends on any series of the Series Preferred Stock accrue or become payable,
(ii) the preferences with





                                       8
<PAGE>   9
respect to dividends and liquidation payments set forth in Section 1 and 2 or
(iii) the percentage of the holders of the Series Preferred Stock required to
approve any changes described in clauses (i) or (ii) above, without the prior
written consent of the holders of at least three-fourths (3/4s) of each of the
Series 1 Preferred Stock and the Series 3 Preferred Stock, as applicable, then
outstanding; and, provided further, that no change in the terms hereof may be
accomplished by merger or consolidation of the Corporation with another
corporation unless the Corporation has obtained the prior written consent of
the holders of the applicable percentages of the Series 1 Preferred Stock and
the Series 3 Preferred Stock then outstanding.

         IN WITNESS WHEREOF, the Corporation has caused this Restated
Certificate of Incorporation to be signed and attested by its duly authorized
officers this 31st day of January 1994.

                         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>   12


   (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>   13
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>   14
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>   15
(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>   16
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>   17
(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>   18
"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:

</TABLE>

   (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>   19
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>   20
     (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>   21
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>   22
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

   (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>   24
   (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>   25
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>   26
   (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>   27
  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>   28
  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>   29
  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>   30
  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>   31
  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>   32
  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>   33
  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>   34
    (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>   35
  "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>   36
  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>   37
  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>   38
  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>   39
   (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>   40
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>   41
  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>   42
  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>   43
  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>   44
  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
  Control Offer shall cease to accrue dividends after the Change of Control
  Payment Date;

    (E) that holders electing to have any shares of Convertible Preferred Stock
  purchased pursuant to a Change of Control Offer will be required to surrender
  such shares of Convertible Preferred Stock, properly endorsed for transfer,
  together with such other customary documents as the Company and the Transfer
  Agent may reasonably request to the Transfer Agent and registrar for the
  Convertible Preferred Stock at the address specified in the notice prior to
  the close of business on the Business Day prior to the Change of Control
  Payment Date;

    (F) that holders will be entitled to withdraw their election if the Company
  receives, not later than five Business Days prior to the Change of Control
  Payment Date, a telegram, a telex, facsimile transmission or letter setting
  forth the name of the holder, the number of shares of Convertible Preferred
  Stock the holder delivered for purchase and a statement that such holder is
  withdrawing his election to have such shares of Convertible Preferred Stock
  purchased;

    (G) that holders whose shares of Convertible Preferred Stock are purchased
  only in part will be issued a new certificate representing the unpurchased
  shares of Convertible Preferred Stock; and


                                       34
<PAGE>   45
    (H) the circumstances and relevant facts regarding such Change of Control.

    If the Change of Control Offer would not be permitted under the Indenture 
or other indebtedness of the Company, such notice shall state the Conversion 
Price as adjusted pursuant to paragraph (g)(ix).

    (iv)  The Company will comply with any tender offer rules under the Exchange
Act which then may be applicable, including Rules 13e-4 and 14e-1, in
connection with any offer required to be made by the Company to repurchase the
shares of Convertible Preferred Stock as a result of a Change of Control.  To
the extent that the provisions of any securities laws or regulations conflict
with provisions of this Certificate of Designation, the Company shall comply
with the applicable securities laws and regulations and shall not be deemed to
have breached its obligations under this Certificate of Designation by virtue
thereof.

    (v)  On the Change of Control Payment Date the Company shall (A) accept for
payment the shares of Convertible Preferred Stock validly tendered pursuant to
the Change of Control Offer, (B) pay to the holders of shares so accepted the
purchase price therefor in cash and (C) cancel and retire each surrendered
certificate.  Unless the Company defaults in the payment for the shares of
Convertible Preferred Stock tendered pursuant to the Change of Control Offer,
dividends will cease to accrue with respect to the shares of Convertible
Preferred Stock tendered and all rights of holders of such tendered shares will
terminate, except for the right to receive payment therefor, on the Change of
Control Payment Date.

    (vi)  To accept the Change of Control Offer, the holder of a share of
Convertible Preferred Stock shall deliver, on or before the 10th day prior to
the Change of Control Payment Date, written notice to the Company (or an agent
designated by the Company for such purpose) of such holder's acceptance,
together with certificates evidencing the shares of Convertible Preferred Stock
with respect to which the Change of Control Offer is being accepted, duly
endorsed for transfer.

    (i)  Reissuance of Convertible Preferred Stock.  Shares of Convertible
Preferred Stock that have been issued and reacquired in any manner, including
shares purchased or redeemed or exchanged, shall not be reissued as shares of


                                       35
<PAGE>   46
  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
Business Day.

   (k)  Limitation on Mergers and Asset Sales.  The Company may not consolidate
with or merge with or into, or convey, transfer or lease all or substantially
all its assets to, any person unless:  (1) the successor, transferee or lessee
(if not the Company) is organized and existing under the laws of the United
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
in the form of Exhibit A, which is hereby incorporated in and expressly made a
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>   47
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>   48
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

   The Transfer Agent shall authenticate and deliver  1,000,000 shares of
Convertible Preferred Stock for original issue upon a written order of the

Officer or either an Assistant Treasurer or Assistant Secretary of the Company.
Such orders shall specify the number of shares of Convertible Preferred Stock

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

  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

Attention:  [          ]

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>   76
   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.

                         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 (i) pursuant to authority conferred upon the
board of directors of the Company (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 Sections
141(c)(2) and 151 of the General Corporation Law of the State of Delaware, said

                  RESOLVED that, pursuant to the authority vested in the Board
         of Directors by its Restated Certificate of Incorporation, and the
         authority vested by such Board of Directors in a committee of the Board

<PAGE>   81
                                                                               2

         per share, initially consisting of up to 450,000 shares (collectively,
         the "Exchangeable Preferred Stock") 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 (i) a series of Preferred
Stock designated as the "12 1/2% Junior Exchangeable Preferred Stock Due 2009"
(the "Initial Exchangeable Preferred Stock") and (ii) a series of Preferred
Stock designated as the "12 1/2% Series B Junior Exchangeable Preferred Stock
Due 2009" (the "Series B Stock"). The number of shares constituting the Initial
Exchangeable Preferred Stock shall be 450,000, and the number of shares
constituting the Series B Stock shall be 450,000. The Initial Exchangeable
Preferred Stock and the Series B Stock are referred to as the Exchangeable
Preferred Stock. The liquidation preference of the Exchangeable Preferred Stock
shall be $1000 per share (the "Liquidation Preference").

                  (b) Rank. The Exchangeable 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 Exchangeable 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 share of Convertible
Preferred Stock now or hereafter outstanding and on a parity with each other
class of Capital Stock or series of Preferred Stock established hereafter by the
Board of Directors of the 

<PAGE>   82
                                                                               3

Company, the terms of which expressly provide that such class or series will
rank on a parity with the Exchangeable 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 Exchangeable Preferred Stock
as to dividend rights or rights on liquidation, winding-up and dissolution of
the Company (collectively referred to as "Senior Stock"). All claims of the
holders of the Exchangeable 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
Exchangeable 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, cumulative preferential dividends on each share of the
Exchangeable Preferred Stock at a rate per annum equal to 12 1/2% of the
Liquidation 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
Exchangeable Preferred Stock 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 Exchangeable Preferred Stock, which Additional Dividends shall accrue as
follows if any of the following events occur (each such event in clauses (A),
(B) and (C) below being herein called a "Registration Default"): (A) if by
October 6, 1997, neither the Exchange Offer Registration Statement nor the Shelf
Registration Statement has been filed with the SEC; (B) if by January 19, 1998,
neither the Registered Exchange Offer is consummated nor the Shelf 


<PAGE>   83
                                                                               4

Registration Statement declared effective by the SEC; or (C) if after January
19, 1998 and after either the Exchange Offer Registration Statement or the Shelf
Registration Statement is declared effective, such Registration Statement
thereafter ceases to be effective (in each case except as permitted below) in
connection with resales of Exchangeable Preferred Stock in accordance with and
during the periods specified herein.

                  Additional Dividends shall accrue on the shares of
Exchangeable Preferred Stock 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 .50% per annum.

                  A Registration Default referred to in clause (C) of paragraph
(c)(i) shall be deemed not to have occurred and be continuing in relation to a
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 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 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 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 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), (B) or (C) 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 


<PAGE>   84
                                                                               5

respect to the Exchangeable 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 Exchangeable
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 Exchangeable 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 Exchangeable Preferred Stock issued in payment of a
dividend, from the date of issuance of such additional shares of Exchangeable
Preferred Stock, and shall be payable quarterly in arrears on each February 15,
May 15, August 15 and November 15 (each, a "Dividend Payment Date"), commencing
on November 15, 1997, to holders of record on the February 1, May 1, August 1
and November 1 immediately preceding the relevant Dividend Payment Date. Any
dividend on the Exchangeable Preferred Stock payable pursuant to this paragraph
(c)(i) on or prior to February 15, 2001 shall be, at the option of the Company,
payable (1) in cash or (2) through the issuance of a number of additional shares
(including fractional shares) of Exchangeable 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 February 15,
2001, all dividends shall be payable in cash.

                  Any dividend accruing after February 15, 2001 that is not paid
in cash on the relevant Dividend Payment Date shall accrue interest at a rate
per annum equal to the then applicable dividend rate per annum from such
Dividend Payment Date to the date of payment of such dividend. Such interest, if
any, shall be payable in cash on each Dividend Payment Date. Any accrued
interest not paid on a Dividend Payment Date shall accrue interest on such
interest pursuant to this paragraph. Any references herein to the payment of


<PAGE>   85
                                                                               6

accrued and unpaid dividends shall be deemed to include any such interest.

                  (ii) In the event the Company notifies the holders of
Exchangeable Preferred Stock of its election not to make a Change of Control
Offer (as defined in paragraph (h)(i)) pursuant to paragraph (h)(iii), then,
within 60 days of the occurrence of the applicable Change of Control, holders of
a majority of the outstanding shares of the Exchangeable Preferred Stock will
designate an Independent Financial Advisor to determine, within 20 days of such
designation, in the opinion of such firm, the appropriate dividend rate that the
Exchangeable Preferred Stock should bear so that, after such reset, the
Exchangeable Preferred Stock would have a market value of 101% of the
Liquidation Preference; provided, however, that no such reset shall be required
to be made if such Independent Financial Advisor determines that the
Exchangeable Preferred Stock has a market value of 101% or greater. If within 5
days of the designation of an Independent Financial Advisor by the Holders, the
Company determines that such Independent Financial Advisor is reasonably
unacceptable to the Company, the Company shall designate a second Independent
Financial Advisor to determine, within 15 days of such designation, in its
opinion, such an appropriate reset dividend rate for the Exchangeable Preferred
Stock. In the event that the two Independent Financial Advisors cannot agree,
within 25 days of the designation of an Independent Financial Advisor by the
Holders of a majority of the outstanding shares of the Exchangeable Preferred
Stock, on the appropriate reset dividend rate, the two Independent Financial
Advisors shall, within 10 days of such 25th day, designate a third Independent
Financial Advisor, which, within 15 days of designation, will determine, in its
opinion, an appropriate reset dividend rate which is between the two rates
selected by the first two Independent Financial Advisors. Upon the determination
of the reset rate, the Exchangeable Preferred Stock shall accrue and accumulate
dividends at the reset rate as of the date of occurrence of the Change of
Control; provided, however, that the reset rate shall in no event be less than
12 1/2% per annum or greater than 15% per annum. The reasonable fees and
expenses including reasonable fees and expenses of legal counsel, if any, and
customary 


<PAGE>   86
                                                                               7

indemnification of each of the three above-referenced Independent Financial
Advisors, shall be borne by the Company.

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

                  (iv) No dividend 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 Exchangeable
Preferred Stock. If full dividends are not so paid, the Exchangeable Preferred
Stock will share dividends pro rata with the Parity Stock.

                  (v) 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 Exchangeable Preferred Stock and any Parity Stock
at the time such 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 Exchangeable 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.

                  (vi) 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 


<PAGE>   87
                                                                               8

to the payment thereof, as may be fixed by the Board of Directors of the
Company.

                  (vii) Dividends payable on the Exchangeable 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 Exchangeable
Preferred Stock for a full Dividend Period will be computed by dividing the per
annum dividend rate by four.

                  (d) Liquidation Preference. (i) Upon any voluntary or
involuntary liquidation, dissolution or winding-up of the Company, holders of
Exchangeable 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 Exchangeable Preferred Stock, plus,
without duplication, an amount in cash equal to all accumulated and unpaid
dividends (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 Exchangeable 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 Exchangeable Preferred Stock and all Parity Stock are not paid in full, the
Exchangeable 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
Exchangeable 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 Exchangeable Preferred Stock
(and, if applicable, an amount equal to a prorated dividend), the holders of
shares of Exchangeable Preferred Stock will not be entitled to any 


<PAGE>   88
                                                                               9

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) Except as set
forth in clause (B) below, the Exchangeable Preferred Stock shall not be
redeemable at the option of the Company prior to August 15, 2002. On or after
August 15, 2002, each share of the Exchangeable 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 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 "Optional
Redemption Price"), if redeemed during the 12-month period beginning August 15
of each of the years set forth below:

</TABLE>

                  (B) At any time and from time to time prior to August 15,
2000, the Company may redeem in the aggregate up to 35% of the outstanding
shares of Exchangeable Preferred 


<PAGE>   89
                                                                              10

Stock with the proceeds of one or more Public Equity Offerings at a redemption
price (expressed as a percentage of the Liquidation Preference thereof) of
112.500% plus accrued and unpaid dividends, if any, to the redemption date
(including an amount in cash equal to a prorated dividend for any partial
dividend period); provided, however, that at least $195 million aggregate
Liquidation Preference of the Exchangeable Preferred Stock remains outstanding
after each such redemption.

                  (C) In the event of a redemption of only a portion of the then
outstanding shares of Exchangeable 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 Exchangeable
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 August 15, 2009 (the "Mandatory Redemption Date") at a price equal
to 100% of the Liquidation Preference of such share, plus, without duplication,
all accrued and unpaid dividends thereon (including 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 Exchangeable
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
subparagraph (iii)(B) and the funds necessary for redemption (including an
amount 


<PAGE>   90
                                                                              11

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 Exchangeable Preferred Stock, not
fewer than 30 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 Exchangeable 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;

                  (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
         Exchangeable Preferred Stock are to be redeemed and the total number of
         shares of the Exchangeable 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 


<PAGE>   91
                                                                              12

         the price designated, his certificate or certificates representing the
         shares of Exchangeable Preferred Stock to be redeemed; and

                  (6) that dividends on the shares of the Exchangeable 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 Exchangeable Preferred Stock shall
surrender the certificate or certificates representing such shares of
Exchangeable 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 Exchangeable Preferred
Stock, except as otherwise required under Delaware law or as set forth in
paragraphs (ii) and (iii) below, shall not be entitled 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 Exchangeable Preferred Stock
are in arrears and unpaid for six or more Dividend Periods (whether or not
consecutive) (a "Dividend Default"); (2) the Company fails to redeem the
Exchangeable Preferred Stock on August 15, 2009, or fails to otherwise discharge
any redemption obligation with respect to the Exchangeable Preferred Stock; (3)
a breach or violation of any of the provisions set forth under paragraph (l)
(Certain Additional Provisions) occurs and the breach or violation continues for
a period of 30 days or more after the Company 


<PAGE>   92
                                                                              13

receives notice thereof specifying the default from the holders of at least 25%
of the shares of Exchangeable Preferred Stock then outstanding; or (4) the
Company fails to pay at final maturity (giving effect to any applicable grace
period) the principal amount of any Indebtedness of the Company or any
Significant Subsidiary (other than any Permitted PSINet Non-Recourse Debt) or
the final maturity of any such Indebtedness is accelerated because of a default
and the total amount of such Indebtedness unpaid or accelerated exceeds $5
million, then the number of directors constituting the Board of Directors of the
Company will, subject to paragraph (f)(ii)(E), be increased by two and the
Holders of the then outstanding shares of Exchangeable 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),(2),(3) or (4) above is a "Voting Rights Triggering Event".

                  (B) The voting rights set forth in paragraph (f)(ii)(A) above
will continue until such time as (x) in the case of a Dividend Default, all
dividends in arrears on the Exchangeable Preferred Stock are paid in full in
cash or (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 a majority of the outstanding shares of Exchangeable Preferred Stock then
outstanding, at which time the term of any directors elected pursuant to the
provisions of paragraph (f)(ii)(A) above (subject to the right of holders of any
other preferred stock to elect directors) shall terminate forthwith 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 Exchangeable Preferred Stock (together with the
holders of Parity Stock upon which like rights have been conferred and are
exercisable) pursuant to paragraph (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% 


<PAGE>   93
                                                                              14

of the shares of Exchangeable 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 Exchangeable 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; 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 Exchangeable 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 Exchangeable Preferred Stock or such Parity Stock so designated shall have,
and the Company shall provide, access to the lists of holders of Exchangeable
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 Exchangeable
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 Exchangeable 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 


<PAGE>   94
                                                                              15

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 Exchangeable 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 Exchangeable Preferred Stock (and such Parity Stock) may be
filled by the remaining director elected by the Holders of Exchangeable
Preferred Stock (and such Parity Stock) unless and until such vacancy shall be
filled by the Holders of Exchangeable Preferred Stock (and such Parity Stock).

                  (E) In the event that an event occurs at any time which
results in the holders of any Parity Stock having voting rights to elect
directors to the Board of Directors, holders of Exchangeable Preferred Stock
shall, whether or not such event otherwise constitutes a Voting Rights
Triggering Event pursuant to paragraph (f)(ii)(A), have the voting rights set
forth in paragraphs (f)(ii)(A) and (f)(ii)(B), and such event shall be deemed
(for purposes of this paragraph (f) only) to constitute a Voting Rights
Triggering Event. In addition, in the event that during a time in which
directors elected by the holders of Exchangeable Preferred Stock pursuant to
this paragraph (f)(ii) are serving on the Board of Directors ("Previously-
Elected Directors") an event occurs which results in holders of Parity Stock
having voting rights to elect (voting together with the holders of Exchangeable
Preferred Stock) at least two directors to the Board of Directors, the holders
of Exchangeable Preferred Stock shall vote together with the holders of such
Parity Stock to elect such new directors, and upon the election of the new
directors the Previously-Elected Directors shall (unless such Previously-
Elected Directors are elected as new directors) cease to serve on the Board of
Directors.

                  (iii) (A) So long as any shares of the Exchangeable 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 



<PAGE>   95
                                                                              16

two-thirds of the shares of Exchangeable 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 Exchangeable 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 Exchangeable Preferred Stock or to authorize the
issuance of any additional shares of Exchangeable Preferred Stock (except to
authorize the issuance of additional shares of Exchangeable Preferred Stock to
be paid as dividends on the Exchangeable Preferred Stock, for which no consent
shall be necessary) without the affirmative vote or consent of Holders of at
least a majority of the issued and outstanding shares of Exchangeable 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
Exchangeable 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 Exchangeable Preferred Stock and shall not be
deemed to affect adversely the rights, preferences, privileges or voting rights
of shares of Exchangeable Preferred Stock.

                  (D) Prior to the exchange of Exchangeable Preferred Stock for
Exchange Debentures, the Company shall not amend or modify the Exchange
Indenture (except as expressly provided therein in respect of amendments without
the consent of holders of Exchange Debentures) without 


<PAGE>   96
                                                                              17

the affirmative vote or consent of holders of at least a majority of the shares
of Exchangeable 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.

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

                  (g) Exchange. (i) Exchange for Debentures. (A) The Company
may, at its option, on any scheduled Dividend Payment Date, exchange the
Exchangeable Preferred Stock, in whole but not in part, for the Exchange
Debentures; provided however, that (1) on the date of such exchange there are no
accumulated and unpaid dividends on the Exchangeable Preferred Stock (including
the dividends payable on such date) or other contractual impediment to such
exchange; (2) there shall be funds legally available sufficient therefor; (3)
immediately after giving effect to such exchange, no Default (as defined in the
Exchange Indenture) shall have occurred and be continuing, and (iv) the Company
shall have delivered to the Trustee under the Exchange Indenture an opinion of
counsel with respect to the due authorization and issuance of the Exchange
Debentures.

                  (B) Upon any exchange pursuant to this paragraph (g)(i),
holders of outstanding shares of Exchangeable Preferred Stock will be entitled
to receive $1.00 principal amount of Exchange Debentures for each $1.00 of
liquidation preference of Exchangeable Preferred Stock held by them. Exchange
Debentures issued in exchange for Exchangeable Preferred Stock will be issued in
principal amounts of $1,000 and integral multiples thereof to the extent
possible, and will also be issued in principal amounts less than $1,000 so that
each holder of Exchangeable Preferred Stock will receive certificates
representing the entire amount of Exchange Debentures to which such holder's
shares of Exchangeable Preferred Stock entitle such holder; 

<PAGE>   97
                                                                              18

provided, however, that the Company may pay cash in lieu of issuing an Exchange
Debenture in a principal amount less than $1,000.

                  (ii) Procedures. (A) The Company will send a written notice of
exchange (the "Exchange Notice") by mail to each holder of record of shares of
Exchangeable Preferred Stock not fewer than 30 days nor more than 60 days before
the date fixed for such exchange (the "Exchange Date"); provided, however, that
no failure to give such notice nor any deficiency therein shall affect the
validity of the procedure for the exchange of any shares of Exchangeable
Preferred Stock to be exchanged 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 Exchange Notice shall state:

                  (1) the Exchange Date;

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

                  (3) that dividends on the shares of Exchangeable Preferred
         Stock to be exchanged shall cease to accrue on such Exchange Date
         whether or not certificates for shares of Exchangeable Preferred Stock
         are surrendered for exchange on such Exchange Date unless the Company
         shall default in the delivery of Exchange Debentures; and

                  (4) that interest on the Exchange Debentures shall accrue from
         the Exchange Date whether or not certificates for shares of
         Exchangeable Preferred Stock are surrendered for exchange on such
         Exchange Date.

                  (B) On and after the Exchange Date, dividends will cease to
accrue on the outstanding shares of Exchangeable Preferred Stock, and all rights
of the holders of Exchangeable Preferred Stock (except the right to receive
Exchange Debentures, an amount in cash, to the extent 


<PAGE>   98
                                                                              19

applicable, equal to the accumulated and unpaid dividends to the Exchange Date
and, if the Company so elects, cash in lieu of any Exchange Debenture that is in
a principal amount that is not an integral multiple of $1,000) will terminate.
The person entitled to receive the Exchange Debentures issuable upon such
exchange will be treated for all purposes as the registered holder of such
Exchange Debentures.

                  (C) On or before the Exchange Date, each holder of
Exchangeable Preferred Stock shall surrender the certificate or certificates
representing such shares of Exchangeable Preferred Stock, in the manner and at
the place designated in the Exchange Notice. The Company shall cause the
Exchange Debentures to be executed on the Exchange Date and, upon surrender in
accordance with the Exchange Notice of the certificates for any shares of
Exchangeable Preferred Stock so exchanged, duly endorsed (or otherwise in proper
form for transfer, as determined by the Company), such shares shall be exchanged
by the Company into Exchange Debentures. The Company shall pay interest on the
Exchange Debentures at the rate and on the dates specified therein from the
Exchange Date.

                  (iii) No Exchange in Certain Cases. Notwithstanding the
foregoing provisions of this paragraph (g), the Company shall not be entitled to
exchange the Exchangeable Preferred Stock for Exchange Debentures if such
exchange, or any term or provision of the Exchange Indenture or the Exchange
Debentures, or the performance of the Company's obligations under the Exchange
Indenture or the Exchange Debentures, shall materially violate or conflict with
any applicable law or agreement or instrument then binding on the Company or if,
at the time of such exchange, the Company is insolvent or if it would be
rendered insolvent by such exchange.

                  (iv) Exchange of Initial Exchangeable Preferred Stock for
Series B Stock. The Series B Stock will be issued by the Company only in
connection with an exchange offer, on a share for share basis, for the Initial
Exchangeable Preferred Stock as required pursuant to the Registration Rights
Agreement. Each share of Series B Stock issued in exchange for a share of
Initial Exchangeable Preferred Stock 


<PAGE>   99
                                                                              20

will be deemed to have the same liquidation preference and accrued and unpaid
dividends as the share of Initial Exchangeable Preferred Stock so exchanged.

                  (h) Change of Control. (i) Upon the occurrence of a Change of
Control (the date of such occurrence being the "Change of Control Date"), the
Company shall either (1) offer to purchase each holder's Exchangeable Preferred
Stock in cash pursuant to the offer described in paragraph (h)(iii) (the "Change
of Control Offer") at a purchase price equal to 101% of the Liquidation
Preference thereof, plus, without duplication, 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) notify each holder of the Company's election not to make an offer as
described in clause (1) above, in which case the dividend rate on the
Exchangeable Preferred Stock shall be subject to reset pursuant to paragraph
(c)(ii).

                  (ii) Prior to the mailing of the notice referred to in
paragraph (h)(iii), but in any event within 30 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 Exchangeable Preferred Stock would violate or constitute a default under
the indebtedness of the Company.

                  (iii) Within 30 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 Exchangeable Preferred Stock. Such notice shall state whether the Company has
elected to make an offer to purchase shares of Exchangeable Preferred Stock and
if it has so elected, such notice shall contain all instructions and materials
necessary to enable such holders to tender Exchangeable Preferred Stock pursuant
to the Change of 


<PAGE>   100
                                                                              21

Control Offer. If the Company has elected to make a Change of Control Offer,
such notice shall state:

                  (A) that a Change of Control has occurred, that a Change of
         Control Offer is being made pursuant to this paragraph (h) and that all
         Exchangeable 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 60 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 Exchangeable Preferred Stock not
         tendered will continue to accrue dividends;

                  (D) that, unless the Company defaults in making payment
         therefor, any share of Exchangeable Preferred Stock accepted for
         payment pursuant to the Change of Control Offer shall cease to accrue
         dividends after the Change of Control Payment Date;

                  (E) that holders electing to have any shares of Exchangeable
         Preferred Stock purchased pursuant to a Change of Control Offer will be
         required to surrender stock certificates representing such shares of
         Exchangeable Preferred Stock, properly endorsed for transfer, together
         with such other customary documents as the Company and the Transfer
         Agent may reasonably request to the Transfer Agent and registrar for
         the Exchangeable Preferred Stock at the address specified in the notice
         prior to the close of business on the Business Day prior to the Change
         of Control Payment Date;

                  (F) that holders will be entitled to withdraw their election
         if the Company receives, not later than five Business Days prior to the
         Change of Control Payment Date, a telegram, a telex, facsimile
         transmission or letter setting forth the name of the 


<PAGE>   101
                                                                              22

         holder, the number of shares of Exchangeable Preferred Stock the holder
         delivered for purchase and a statement that such holder is withdrawing
         his election to have such shares of Exchangeable Preferred Stock
         purchased;

                  (G) that holders whose shares of Exchangeable Preferred Stock
         are purchased only in part will be issued a new certificate
         representing the unpurchased shares of Exchangeable Preferred Stock;
         and

                  (H) the circumstances and relevant facts regarding such Change
         of Control (including information with respect to pro forma historical
         income, cash flow and capitalization after giving effect to such Change
         of Control).

                  If the Company elects not to make a Change of Control Offer,
such notice shall state that the dividend rate on the Exchangeable Preferred
Stock is subject to adjustment pursuant to paragraph (c)(ii).

                  (iv) The Company will comply with any tender offer rules under
the Exchange Act which then may be applicable, including Rules 13e-4 and 14e-1,
in connection with any offer made by the Company to repurchase the shares of
Exchangeable Preferred Stock as a result of a Change of Control. To the extent
that the provisions of any securities laws or regulations conflict with
provisions of this Certificate of Designation, the Company shall comply with the
applicable securities laws and regulations and shall not be deemed to have
breached its obligations under this Certificate of Designation by virtue
thereof.

                  (v) On the Change of Control Payment Date the Company shall
(A) accept for payment the shares of Exchangeable Preferred Stock validly
tendered pursuant to the Change of Control Offer, (B) pay to the holders of
shares so accepted the purchase price therefor in cash and (C) cancel each
surrendered certificate and retire the shares represented thereby. Unless the
Company defaults in the payment for the shares of Exchangeable Preferred Stock
tendered pursuant to the Change of Control Offer, dividends will cease to accrue
with respect to the shares of 


<PAGE>   102
                                                                              23

Exchangeable Preferred Stock tendered and all rights of holders of such tendered
shares will terminate, except for the right to receive payment therefor, on the
Change of Control Payment Date.

                  (vi) To accept the Change of Control Offer, the holder of a
share of Exchangeable Preferred Stock shall deliver, on or before the 10th day
prior to the Change of Control Payment Date, written notice to the Company (or
an agent designated by the Company for such purpose) of such holder's
acceptance, together with certificates evidencing the shares of Exchangeable
Preferred Stock with respect to which the Change of Control Offer is being
accepted, duly endorsed for transfer.

                  (i) Conversion or Exchange. Except as otherwise provided
herein, the holders of shares of Exchangeable Preferred Stock shall not have any
rights hereunder to convert such shares into or exchange such shares for shares
of any other class or classes or of any other series of any class or classes of
Capital Stock of the Company.

                  (j) Reissuance of Exchangeable Preferred Stock. Shares of
Exchangeable Preferred Stock that have been issued and reacquired in any manner,
including shares purchased or redeemed or exchanged, shall not be reissued as
shares of Exchangeable 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

end of the period referred to below and the receipt and application of the
proceeds thereof, either (i) the Indebtedness to Operating Cash Flow Ratio for

                  (2) Indebtedness owed to and held by the Company or a
         Restricted Subsidiary; provided, however, that any subsequent issuance
         or transfer of any Capital Stock which results in any Restricted
         Subsidiary ceasing to be a Restricted Subsidiary or any subsequent
         transfer of such Indebtedness (other than to the Company or another
         Restricted Subsidiary) shall be deemed, in each case, to constitute the
         Incurrence of such Indebtedness by the issuer thereof;

                  (3) the Exchange Debentures (including Exchange Debentures
         issued in lieu of cash interest payments with respect to Exchange

         obligations, in each case Incurred for the purpose of financing all or
         any part of the purchase price or cost of construction or improvement
         of property used in the business of the Company or such Restricted
         Subsidiary;

                  (8) In the event that the PSINet Shares are held by the
         Company or a Restricted Subsidiary, the Incurrence by the Company or
         such Restricted Subsidiary of Permitted PSINet Non-Recourse Debt; and

                  (9) Indebtedness in an aggregate principal amount at any time
         outstanding which, together with the amount of all other Indebtedness

         through (8) of this paragraph (l)(ii)(B) and paragraph (l)(ii)(A)),
         does not exceed 5% of Consolidated Tangible Assets.

         (C) Notwithstanding the foregoing, the Company shall not Incur any
Indebtedness pursuant to paragraph (l)(ii)(B) if the proceeds thereof are used,
directly or indirectly, to Refinance any Subordinated Obligations unless such
Indebtedness shall be subordinated to the Exchange Debentures to at least the
same extent as such Subordinated Obligations.

         (D) For purposes of determining compliance with this paragraph (l)(ii),
(1) in the event that an item of Indebtedness meets the criteria of more than
one of the types of Indebtedness described above, the Company, in its sole
discretion, will classify such item of Indebtedness and only be required to
include the amount and type of such Indebtedness in one of the above clauses and

the Company or such Restricted Subsidiary makes such Restricted Payment:

                  (1) a Voting Rights Triggering Event shall have occurred and

                  (2) the Company is not able to Incur an additional $1.00 of
         Indebtedness under paragraph (l)(ii)(A); or

                  (3) the aggregate amount of such Restricted Pay ment and all
         other Restricted Payments since the Issue Date would exceed the sum of:

                           (I) an amount equal to the Cumulative Operating Cash
                  Flor for the period (taken as one accounting period) from the
                  beginning of the first full fiscal quarter commencing after
                  the Issue Date to the end of the Company's most recently ended
                  fiscal quarter for which internal financial statements are
                  available at the time of such Restricted Payment less 1.50
                  times the Company's Cumulative Consolidated Interest Expense
                  for such period;

                           (II) the aggregate Net Cash Proceeds received by the
                  Company from the issuance or sale of its Parity Stock and
                  Junior Stock (in each case other than Disqualified Stock)
                  subsequent to the Issue Date (other than an issuance or sale
                  to a Subsidiary of the Company and other than an issuance or
                  sale to an employee stock ownership plan or to a trust
                  established by the Company or any of its Subsidiaries for the
                  benefit of their employees);

                           (III) the amount by which Indebtedness of the Company
                  is reduced on the Company's balance sheet upon the conversion
                  or exchange (other than by a Subsidiary of the Company)
                  subsequent to the Issue Date of any Indebtedness of the
                  Company convertible or exchangeable for Parity Stock or Junior
                  Stock (in each case other than Disqualified

                                                                              28
                  Stock) of the Company (less the amount of any cash, or the
                  fair value of any other property, distributed by the Company
                  upon such conversion or exchange); and

                           (IV) an amount equal to the sum of (x) the net
                  reduction in Investments in any Person resulting from
                  dividends, repayments of loans or advances or other transfers
                  of assets (but excluding such interest, dividends, repayments,
                  advances or other transfers of assets to the extent any such
                  item increases Consolidated Net Income), in each case to the
                  Company or any Restricted Subsidiary from any Person
                  (including, without limitation, from Unrestricted
                  Subsidiaries), and (y) the portion (proportionate to the
                  Company's equity interest in such Subsidiary) of the fair
                  market value of the net assets of an Unrestricted Subsidiary
                  at the time such Unrestricted Subsidiary is designated a
                  Restricted Subsidiary; provided, however, that the foregoing
                  sum shall not exceed, in the case of any Person (including any
                  Unrestricted Subsidiary), the amount of Investments previously
                  made (and treated as a Restricted Payment) by the Company or
                  any Restricted Subsidiary in such Person.

                  (B) The provisions of paragraph (l)(iii)(A) shall not
prohibit:

                  (1) any Restricted Payment made out of the proceeds of the
         substantially concurrent sale of, or any acquisition of any Parity
         Stock or Junior Stock of the Company made by exchange for, other Parity
         Stock or Junior Stock, as the case may be, of the Company (in each case
         other than Disqualified Stock and other than Parity Stock or Junior
         Stock issued or sold to a Subsidiary of the Company or an employee
         stock ownership plan or to a trust established by the Company or any of
         its Subsidiaries for the benefit of their employees); provided,
         however, that (I) such Restricted Payment shall be excluded in the
         calculation of the amount of Restricted Payments and (II) the Net Cash
         Proceeds from such sale shall be excluded from the 


<PAGE>   108
                                                                              29

         calculation of amounts under paragraph (l)(iii)(A)(3)(II);

                  (2) dividends paid within 60 days after the date of
         declaration thereof if at such date of declaration such dividend would
         have complied with paragraph (l)(iii); provided, however, that at the
         time of payment of such dividend, no other Voting Rights Triggering
         Event shall have occurred and be continuing (or result therefrom);
         provided further, however, that such dividend shall be included in the
         calculation of the amount of Restricted Payments; or

                  (3) the repurchase or other acquisition of shares of, or
         options to purchase shares of, common stock of the Company or any of
         its Subsidiaries from employees, former employees, directors or former
         directors of the Company or any of its Subsidiaries (or permitted
         transferees of such employees, former employees, directors or former
         directors), pursuant to the terms of the agreements (including
         employment agreements) or plans (or amendments thereto) approved by the
         Board of Directors under which such individuals purchase or sell or are
         granted the option to purchase or sell, shares of such common stock;
         provided, however, that the aggregate amount of such repurchases and
         other acquisitions shall not exceed $1,000,000 in any calendar year;
         provided further, however, that such repurchases and other acquisitions
         shall be excluded in the calculation of the amount of Restricted
         Payments.

                  (iv) Limitation on Restrictions on Distributions from
Restricted Subsidiaries. The Company shall not, and shall not permit any
Restricted Subsidiary to, create or otherwise cause or permit to exist or become
effective any consensual encumbrance or restriction on the ability of any
Restricted Subsidiary to (A) pay dividends or make any other distributions on
its Capital Stock to the Company or a Restricted Subsidiary or pay any
Indebtedness owed to the

         Date;

                  (2) any encumbrance or restriction with respect to a
         Restricted Subsidiary pursuant to an agreement relating to any

         date on which such Restricted Subsidiary was acquired by the Company
         (other than Indebtedness Incurred as consideration in, or to provide
         all or any portion of the funds or credit support utilized to
         consummate, the transaction or series of related transactions pursuant
         to which such Restricted Subsidiary became a Restricted Subsidiary or
         was acquired by the Company) and outstanding on such date;

         effecting a Refinancing of Indebtedness Incurred pursuant to an
         agreement referred to in clause (1) or (2) of this paragraph (l)(iv) or
         this clause (3) or contained in any amendment to an agreement referred
         to in clause (1) or (2) of this paragraph (l)(iv) or this clause (3);
         provided, however, that the encumbrances and restrictions with respect
         to such Restricted Subsidiary contained in any such refinancing
         agreement or amendment are no less favorable to the holders of
         Exchangeable Preferred Stock than encumbrances and restrictions with
         respect to such Restricted Subsidiary contained in such predecessor
         agreements;

                  (4) any such encumbrance or restriction consisting of
         customary nonassignment provisions in leases governing leasehold
         interests to the extent such provisions restrict the transfer of the
         lease or the property leased thereunder;

                  (5) in the case of clause (C) above, restrictions contained in
         IRU Agreements, security agreements or mortgages securing Indebtedness
         or other obligations of a Restricted Subsidiary to the extent such
         restrictions restrict the transfer of the property subject to such
         security agreements or mortgages;

                  (6) any restriction with respect to a Restricted Subsidiary
         imposed pursuant to an agreement entered into for the sale or

         such Restricted Subsidiary pending the closing of such sale or
         disposition; and

                  (7) any such encumbrance or restriction contained
         in the PSINet Agreement.

                  (v) Limitation on Affiliate Transactions. (A) The Company
shall not, and shall not permit any Restricted Subsidiary to, enter into or
permit to exist any transaction (including the purchase, sale, lease or exchange
of any property, employee compensation arrangements or the rendering of any
service) with any Affiliate of the Company (an "Affiliate Transaction") unless
(1) such Affiliate Transaction is on terms that are no less favorable to the
Company or the relevant Restricted Subsidiary than those that would have been
obtained in a comparable transaction by the Company or such Restricted
Subsidiary with an unrelated Person and (2) the Company delivers to the Transfer
Agent (I) with respect to any Affiliate Transaction involving aggregate
consideration in excess of $1,000,000 a resolution of the Board of Directors set

Company and authenticated by the Transfer Agent as hereinafter provided. Subject
to the terms hereof and to the requirements of applicable law, the number of
shares of Exchangeable Preferred Stock represented by Global Exchangeable

made on the records of the Transfer Agent and DTC or its nominee as hereinafter

                  (B) Book-Entry Provisions. In the event Global Exchangeable

                                                                              35

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
Exchangeable Preferred Stock held on their behalf by DTC or by the Transfer
Agent as the custodian of DTC or under such Global Exchangeable 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 Exchangeable
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
exercise of the rights of a holder of a beneficial interest in any Global
Exchangeable Preferred Stock.

                  (C) Certificated Exchangeable Preferred Stock. Exchangeable
Preferred Stock initially sold in offshore transactions pursuant to Regulation S
under the Securities Act will be issued in fully registered certificated form
("Certificated Exchangeable Preferred Stock").

                  Except as otherwise provided by applicable law or as provided
in this paragraph (m)(i) or in paragraph (m)(iii), owners of beneficial
interests in Global Exchangeable Preferred Stock will not be entitled to receive
physical delivery of Certificated Exchangeable Preferred
Stock.

                  After a transfer of any Initial Exchangeable Preferred Stock
during the period of the effectiveness of a Shelf Registration Statement with
respect to such Initial Exchangeable Preferred Stock, all requirements
pertaining to legends on such Initial Exchangeable Preferred Stock will cease to
apply, the requirements requiring that any such Initial Exchangeable Preferred
Stock issued to Holders be issued in global form will cease to apply, and
Certificated Exchangeable Preferred Stock without legends will be 


<PAGE>   115
                                                                              36

available to the transferee of the Holder of such Initial Exchangeable Preferred
Stock upon exchange of such transferring Holder's Initial Exchangeable Preferred
Stock or directions to transfer such Holder's interest in the Global
Exchangeable Preferred Stock, as applicable. Upon the consummation of a
Registered Exchange Offer with respect to the Initial Exchangeable Preferred
Stock pursuant to which Holders of such Initial Exchangeable Preferred Stock are
offered Series B Stock in exchange for their Initial Exchangeable Preferred
Stock, all requirements that Initial Exchangeable Preferred Stock be issued in
global form will cease to apply and Certificated Exchangeable Preferred Stock
with the restricted securities legend set forth in Exhibit A hereto will be
available to Holders of such Initial Exchangeable Preferred Stock that do not
exchange their Initial Exchangeable Preferred Stock, and Series B Stock in
certificated form will be available to Holders that exchange such Initial
Exchangeable Preferred Stock in such Registered Exchange Offer.

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

                  If an Officer whose signature is on certificates representing
Exchangeable Preferred Stock no longer holds that office at the time the
Transfer Agent authenticates the Exchangeable Preferred Stock evidenced thereby,
the shares of Exchangeable Preferred Stock evidenced thereby shall be valid
nevertheless.

                  A certificate representing Exchangeable Preferred Stock shall
not be valid until an authorized signatory of the Transfer Agent manually signs
the certificate of authentication on the Exchangeable Preferred Stock. The
signature shall be conclusive evidence that the Exchangeable Preferred Stock has
been authenticated under this Certificate of Designation.

                                                                              37

                  The Transfer Agent shall authenticate and deliver: (1) 300,000
shares of Initial Exchangeable Preferred Stock for original issue and (2)
300,000 shares of Series B Stock for issue only in a Registered Exchange Offer
pursuant to the Registration Rights Agreement, in each case 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 Exchangeable Preferred Stock to be
authenticated and the date on which the original issue of Exchangeable Preferred
Stock is to be authenticated and whether the Exchangeable Preferred Stock is to
be Initial Exchangeable Preferred Stock or Series B Stock.

                  The Transfer Agent may appoint an authenticating agent
reasonably acceptable to the Company to authenticate the Exchangeable Preferred
Stock. Unless limited by the terms of such appointment, an authenticating agent
may authenticate Exchangeable 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 Exchangeable Preferred Stock. When Certificated Exchangeable
Preferred Stock is presented to the Transfer Agent with a request to register
the transfer of such Certificated Exchangeable Preferred Stock or to exchange
such Certificated Exchangeable Preferred Stock for an equal number of shares of
Certificated Exchangeable 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

         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

                  (2) in the case of Transfer Restricted Securities that are
         Certificated Exchangeable Preferred Stock, are being transferred or
         exchanged pursuant to an effective registration statement under the
         Securities Act or pursuant to clause (I) or (II) below, and are

                  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 B 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 B hereto).

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

by appropriate instruments of transfer, in form satisfactory to the Transfer
Agent, together with:

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

         Preferred Stock to reflect an increase in the number of shares of
         Exchangeable Preferred Stock represented by the Global Exchangeable
         Preferred Stock,

then the Transfer Agent shall cancel such Certificated Exchangeable 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 Exchangeable Preferred Stock represented by the Global
Exchangeable Preferred Stock to be increased accordingly. If no Global
Exchangeable 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 Exchangeable Preferred Stock
representing the appropriate number of shares.

                  (C) Transfer and Exchange of Global Exchangeable Preferred

                  (1) Any person having a beneficial interest in Exchangeable
         Preferred Stock that is being transferred or exchanged pursuant to an
         effective registration statement under the Securities Act or pursuant
         to clause (I) or (II) below may upon request, and if accompanied by the
         information specified below, exchange such beneficial interest for
         Certificated Exchangeable Preferred Stock representing the same number
         of shares of Exchangeable 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 Exchangeable 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 Exchangeable Preferred Stock, a

                  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 B hereto);

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 Exchangeable
Preferred Stock represented by Global Exchangeable Preferred Stock to be reduced

         names such Exchangeable Preferred Stock are so registered in accordance
         with the instructions of DTC.

                  (E) Restrictions on Transfer and Exchange of Global

         to continue as depository for the Global Exchangeable Preferred Stock

         Agent in writing that it elects to cause the issuance of Certificated

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 Exchangeable Preferred Stock to the
persons designated by the Company, will authenticate and deliver Certificated

Stock have either been exchanged for Certificated Exchangeable Preferred Stock,
redeemed, repurchased or canceled, such Global Exchangeable Preferred Stock
shall be returned to DTC for cancelation or retained and canceled by the
Transfer Agent. At any time prior to such cancelation, if any beneficial
interest in Global Exchangeable Preferred Stock is exchanged for Certificated
Exchangeable Preferred Stock, redeemed, repurchased or canceled, the number of
shares of Exchangeable Preferred Stock represented by such Global Exchangeable
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 Exchangeable
Preferred Stock, by the Transfer Agent or DTC, to reflect such reduction.

         Designation as the Certificated Exchangeable Preferred Stock or Global
         Exchangeable Preferred Stock surrendered upon such registration of
         transfer or exchange.

                  (3) Prior to due presentment for registration of transfer of
         any shares of Exchangeable Preferred Stock, the Transfer Agent and the
         Company may deem and treat the person in whose name such shares of
         Exchangeable Preferred Stock are registered as the absolute owner of
         such Exchangeable 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 Exchangeable
         Preferred Stock 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 Exchangeable Preferred Stock Certificates.

                           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 B hereto).

                  (iv) Replacement Certificates. If a mutilated Exchangeable
Preferred Stock certificate is surrendered to the Transfer Agent or if the
Holder of a Exchangeable Preferred Stock certificate claims that the
Exchangeable Preferred Stock certificate has been lost, destroyed or wrongfully
taken, the Company shall issue and the Transfer Agent shall countersign a
replacement Exchangeable 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

sufficient in the judgment of the Company and the Transfer Agent to protect the

<PAGE>   126
                                                                              47

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

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

                  (B) At such time as all beneficial interests in Global
Exchangeable Preferred Stock have either been exchanged for Certificated
Exchangeable Preferred Stock, redeemed, repurchased or canceled, such Global
Exchangeable Preferred Stock shall thereupon be delivered to the Transfer
Agent for cancelation.

                  (C) The Transfer Agent and no one else shall cancel and
destroy all Exchangeable Preferred Stock certificates surrendered for transfer,
exchange, replacement or cancelation and deliver a certificate of such
destruction to the Company unless the Company directs the Transfer Agent to
deliver canceled Exchangeable Preferred Stock certificates to the Company. The
Company may not issue new Exchangeable Preferred Stock certificates to replace
Exchangeable Preferred Stock certificates to the extent they evidence
Exchangeable Preferred Stock which the Company has purchased or otherwise
acquired.

Exchangeable Preferred Stock Due 2009 (the "Exchangeable Preferred Stock") of
IXC Communications, Inc., a Delaware corporation ("the "Company"), we represent
that:

                  (i) the offer of the Exchangeable Preferred Stock was not made
         to a person in the United States;

                  (ii) at the time the buy order was originated, the transferee
         was outside the United States or we and any person acting on our behalf
         reasonably believed that the transferee was outside the United States;

                  (iii) no directed selling efforts have been made by us in the
         United States in contravention of the requirements of Rule 903(b) or
         Rule 904(b) of Regulation S under the Securities Act of 1933 (the
         "Securities Act"), as applicable; and

                  (iv) the transaction is not part of a plan or scheme by us to
         evade the registration requirements of the Securities Act.

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

                         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 (i) pursuant to authority conferred upon the
board of directors of the Company (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 Sections
141(c)(2) and 151 of the General Corporation Law of the State of Delaware, said
Board of Directors is authorized to issue Preferred Stock of the Company in one
or more series and has authorized a committee of the Board of Directors (the
"Finance Committee") to adopt the resolution set forth below and (ii) the
Finance Committee duly approved and adopted the following resolution on March
25, 1998 (the "Resolution"):

               RESOLVED that, pursuant to the authority vested in the Board of
        Directors by its Restated Certificate of Incorporation, and the
        authority vested by such Board of Directors in a committee of the Board
        (the "Finance Committee"), all the members of which are members of such
        Board, the Finance Committee does hereby create, authorize and provide
        for the issuance of 6 3/4% Cumulative Convertible Preferred Stock, par
        value $.01 per share, with a stated value of $1000 per share, initially
        consisting of up to 155,250 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:

               1. 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 "6 3/4% Cumulative Convertible Preferred Stock" (the
"Cumulative Convertible Preferred Stock"). The number of shares constituting the
Cumulative Convertible Preferred Stock shall be 155,250, and such shares shall
be represented by stock certificates substantially in the form set forth in
Exhibit A hereto. The liquidation preference of the Cumulative Convertible
Preferred Stock shall be $1,000 

<PAGE>   167


per share (the "Liquidation Preference"). The date the Cumulative Convertible
Preferred Stock is first issued is referred to as the "Issue Date".

               2. Rank. The Cumulative Convertible Preferred Stock will, rank
(i) pari passu in right of payment with the Company's 7 1/4% Junior Convertible
Preferred Stock Due 2007 (the "7 1/4% Preferred Stock"), the Company's 12 1/2%
Junior Exchangeable Preferred Stock Due 2009 and 12 1/2% Series B Junior
Exchangeable Preferred Stock Due 2009 (collectively, the "Exchangeable Preferred
Stock") and each other class of Capital Stock or series of Preferred Stock
established hereafter by the Board of Directors, the terms of which expressly
provide that such class or series ranks on a parity with the Cumulative
Convertible Preferred Stock as to dividend rights and rights on liquidation,
dissolution and winding up of the Company (collectively referred to, as "Parity
Securities"); (ii) junior in right of payment to any Senior Securities (as
defined) as to dividends and upon liquidation, dissolution or winding up of the
Company and (iii) senior in right of payment as to dividend rights and upon
liquidation, dissolution or winding up of the Company to the Common Stock and
any Capital Stock of the Company that expressly provides that it will rank
junior to the Cumulative Convertible Preferred Stock as to dividend rights or
rights on liquidation, winding up and dissolution of the Company (collectively
referred to as "Junior Securities"). The Company may not authorize, create (by
way of reclassification or otherwise) or issue any class or series of Capital
Stock of the Company ranking senior in right of payment as to dividend rights or
upon liquidation, dissolution or winding up of the Company to the Cumulative
Convertible Preferred Stock ("Senior Securities") or any obligation or security
convertible or exchangeable into, or evidencing a right to purchase, shares of
any class or series of Senior Securities without the affirmative vote or consent
of the holders of at least 66-2/3% of the outstanding shares of Cumulative
Convertible Preferred Stock.

               3. Dividends. The Holders of shares of the Cumulative Convertible
Preferred Stock will be entitled to receive, when, as and if dividends are
declared by the Board of Directors out of funds of the Company legally available
therefor, cumulative preferential dividends from the Issue Date of the
Cumulative Convertible Preferred Stock accruing at the rate of $67.50 per share
of Cumulative Convertible Preferred Stock per annum, or $16.875 per share of
Cumulative Convertible Preferred Stock per quarter, payable quarterly in arrears
on January 1, April 1, July 1, and October 1 of each year or, if any such date
is not a Business Day, on the next succeeding business day (each, a "Dividend
Payment Date"), to the Holders of record as of the next preceding December 15,
March 15, June 15, and September 15 (each, a "Record Date"). Accrued but unpaid
dividends, if any, may be paid on such dates as determined by the Board of
Directors. Dividends will be payable in cash except as set forth below.
Dividends payable on the Cumulative Convertible Preferred Stock will be computed
on the basis of a 360-day year of twelve 30-day months and will be deemed to
accrue on a daily basis. Dividends may, at the option of the Company, be paid in
Common Stock if, and only if, the documents governing the Company's indebtedness
that exists on the Issue Date then prohibit the payment of such dividends in
cash. If the Company elects to pay dividends in shares of Common Stock, the
number of shares of Common Stock to be distributed will be calculated by
dividing the amount of such dividend otherwise payable in cash by 95% of the
arithmetic average of the Closing Price (as defined) for the five Trading Days
(as defined) preceding the Dividend Payment Date. The Cumulative Convertible
Preferred Stock will not be redeemable unless all dividends accrued through such
redemption date shall have been paid in full. 


                                      -2-


<PAGE>   168

Notwithstanding anything to the contrary herein contained, the Company shall not
be required to declare or pay a dividend if another person (including, without
limitation, any of its subsidiaries) pays an amount to the Holders equal to the
amount of such dividend on behalf of the Company and, in such event, the
dividend will be deemed paid for all purposes.

               Dividends on the Cumulative Convertible Preferred Stock will
accrue whether or not the Company has earnings or profits, whether or not there
are funds legally available for the payment of such dividends and whether or not
dividends are declared. Dividends will accumulate to the extent they are not
paid on the Dividend Payment Date for the quarter to which they relate.
Accumulated unpaid dividends will accrue and cumulate at a rate of 6.75% per
annum. The Company will take all reasonable actions required or permitted under
Delaware law to permit the payment of dividends on the Cumulative Convertible
Preferred Stock.

               No dividend whatsoever shall be declared or paid upon, or any sum
set apart for the payment of dividends upon, any outstanding share of the
Cumulative Convertible Preferred Stock with respect to any dividend period
unless all dividends for all preceding dividend periods have been declared and
paid upon, or declared and a sufficient sum set apart for the payment of such
dividend upon, all outstanding shares of Cumulative Convertible Preferred Stock.
Unless full cumulative dividends on all outstanding shares of Cumulative
Convertible Preferred Stock due for all past dividend periods shall have been
declared and paid, or declared and a sufficient sum for the payment thereof set
apart, then: (i) no dividend (other than a dividend payable solely in shares of
Junior Securities or options, warrants or rights to purchase Junior Securities)
shall be declared or paid upon, or any sum set apart for the payment of
dividends upon, any shares of Junior Securities; (ii) no other distribution
shall be declared or made upon, or any sum set apart for the payment of any
distribution upon, any shares of Junior Securities; (iii) no shares of Junior
Securities shall be purchased, redeemed or otherwise acquired or retired for
value (excluding an exchange for shares of other Junior Securities or a
purchase, redemption or other acquisition from the proceeds of a substantially
concurrent sale of Junior Securities) by the Company or any of its subsidiaries;
and (iv) no monies shall be paid into or set apart or made available for a
sinking or other like fund for the purchase, redemption or other acquisition or
retirement for value of any shares of Junior Securities by the Company or any of
its subsidiaries. Holders of the Cumulative Convertible Preferred Stock will not
be entitled to any dividends, whether payable in cash, property or stock, in
excess of the full cumulative dividends as herein described.

               4. Liquidation Preference. Upon any voluntary or involuntary
liquidation, dissolution or winding up of the affairs of the Company after
payment in full of the liquidation preference (and any accrued and unpaid
dividends) on any Senior Securities, each Holder of shares of the Cumulative
Convertible Preferred Stock shall be entitled, on an equal basis with the
holders of the 7 1/4% Preferred Stock, the Exchangeable Preferred Stock and any
other outstanding Parity Securities, to payment out of the assets of the Company
available for distribution of the Liquidation Preference per share of the
Cumulative Convertible Preferred Stock held by such Holder, plus an amount equal
to the accrued and unpaid dividends on the Cumulative Convertible Preferred
Stock and Liquidated Damages (as defined) (if any) to the date fixed for
liquidation, dissolution, or winding up before any distribution is made on any
Junior Securities, including, without limitation, Common Stock of the Company.
After payment in full of the Liquidation Preference and an amount 

                                      -3-

<PAGE>   169

equal to the accrued and unpaid dividends and Liquidated Damages (if any), to
which Holders of Cumulative Convertible Preferred Stock are entitled, such
Holders will not be entitled to any further participation in any distribution of
assets of the Company. However, neither the voluntary 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 corporations
will be deemed to be a voluntary or involuntary liquidation, dissolution or
winding up of the Company, unless such sale, conveyance, exchange, transfer,
consolidation or merger shall be in connection with a liquidation, dissolution
or winding up of the affairs of the Company or reduction or decrease in capital
stock.

               5. Redemption. The Cumulative Convertible Preferred Stock may not
be redeemed at the option of the Company on or prior to April 5, 2000. After
April 5, 2000 the Company may redeem the Cumulative Convertible Preferred Stock.
Notwithstanding the foregoing, prior to April 1, 2002, the Company shall only
have the option to redeem shares of the Cumulative Convertible Preferred Stock
if, during the period of 30 consecutive Trading Days ending on the Trading Day
immediately preceding the date that the notice of redemption is mailed to
Holders, the Closing Price for the Common Stock exceeded $75 divided by the
Conversion Rate effective on the date of such notice for at least 20 of such
Trading Days. Subject to the immediately preceding sentence, the Cumulative
Convertible Preferred Stock may be redeemed, in whole or in part, at the option
of the Company after April 5, 2000, at the redemption prices specified below
(expressed as percentages of the Liquidation Preference thereof), in each case,
together with an amount equal to accrued and unpaid dividends on the Cumulative
Convertible Preferred Stock (excluding any declared dividends for which the
Record Date has passed) and Liquidated Damages (if any), to the date of
redemption, upon not less than 15 nor more than 60 days' prior written notice,
if redeemed during the period commencing on April 5, 2000 to March 31, 2001 at
105.40%, and thereafter during the 12-month period commencing on April 1 of each
of the years set forth below:

               Except as provided in the preceding sentence, no payment or
allowance will be made for accrued dividends on any shares of Cumulative
Convertible Preferred Stock called for redemption.

               On and after any date fixed for redemption (the "Redemption
Date"), provided that the Company has made available at the office of the
Transfer Agent a sufficient amount of cash to effect the redemption, dividends
will cease to accrue on the Cumulative Convertible 


                                      -4-

<PAGE>   170

Preferred Stock called for redemption (except that, in the case of a Redemption
Date after a dividend payment Record Date and prior to the related Dividend
Payment Date, holders of Cumulative Convertible Preferred Stock on the dividend
payment Record Date will be entitled on such Dividend Payment Date to receive
the dividend payable on such shares), such shares shall no longer be deemed to
be outstanding and all rights of the holders of such shares as holders of
Cumulative Convertible Preferred Stock shall cease except the right to receive
the cash deliverable upon such redemption, without interest from the Redemption
Date.

               In the event of a redemption of only a portion of the then
outstanding shares of Cumulative 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.

               With respect to a redemption pursuant hereto, the Company will
send a written notice of redemption by first class mail to each holder of record
of shares of Cumulative 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 Cumulative 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:

                      a. the redemption price;

                      b. whether all or less than all the outstanding shares of
the Cumulative Convertible Preferred Stock are to be redeemed and the total
number of shares of the Cumulative Convertible Preferred Stock being redeemed;

                      c. the Redemption Date;

                      d. 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 Cumulative Convertible Preferred Stock
to be redeemed; and

                      e. that dividends on the shares of the Cumulative
Convertible Preferred Stock to be redeemed shall cease to accumulate on such
Redemption Date unless the Company defaults in the payment of the redemption
price.

               Each holder of Cumulative Convertible Preferred Stock shall
surrender the certificate or certificates representing such shares of Cumulative
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 redemption price 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.

               6. Voting Rights. Holders of record of shares of the Cumulative
Convertible Preferred Stock will have no voting rights, except as required by
law and as provided in this Section 6 and in Sections 2, 8 and 13 hereof. Upon
the accumulation of accrued and unpaid dividends on the outstanding Cumulative
Convertible Preferred Stock in an amount equal to six full quarterly dividends
(whether or not consecutive) (together with any event with a similar effect
pursuant to the terms of any other series of Preferred Stock upon which like
rights have been conferred, a "Voting Rights Triggering Event"), the number of
members of the Company's Board of Directors will be immediately and
automatically increased by two (unless previously increased pursuant to the
terms of any other series of Preferred Stock upon which like rights have been
conferred), and the Holders of a majority of the outstanding shares of
Cumulative Convertible Preferred Stock, voting together as a class (pro rata,
based on liquidation preference) with the holders of any other series of
Preferred Stock upon which like rights have been conferred and are exercisable,
will be entitled to elect two members to the Board of Directors of the Company.
Voting rights arising as a result of a Voting Rights Triggering Event will
continue until such time as all dividends in arrears on the Cumulative
Convertible Preferred Stock are paid in full. Notwithstanding the foregoing,
however, such voting rights to elect directors will expire when the number of
shares of Cumulative Convertible Preferred Stock outstanding is reduced to
13,500 or less.

               In the event such voting rights expire or are no longer
exercisable because dividends in arrears have been paid in full, the term of any
directors elected pursuant to the provisions of this paragraph 6 above shall
terminate forthwith and the number of directors constituting the Board of
Directors shall be immediately and automatically 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 Cumulative Convertible Preferred Stock (together with the holders
of any other series of Preferred Stock upon which like rights have been
conferred and are exercisable) pursuant to this paragraph 6, 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 Cumulative Convertible Preferred Stock
then outstanding or the holders of 25% of the shares of any other series of
Preferred Stock then outstanding upon which like rights have been conferred and
are exercisable addressed to the secretary of the Company shall, call a special
meeting of the Holders of Cumulative Convertible Preferred Stock and the holders
of such other series of Preferred Stock for the purpose of electing the
directors which such holders are entitled to elect pursuant to the terms hereof;
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 (or such vacancies
arise, as the case may be), in which case such meeting shall be deemed to have
been called for such next annual meeting. If such meeting shall not be called,
pursuant to the provision of the immediately preceding sentence, 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 Cumulative Convertible Preferred Stock or
the holders of 25% of the shares of any other series of Preferred Stock upon
which like rights have been conferred 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

                                       -6-

<PAGE>   172



Cumulative Convertible Preferred Stock or such other series of Preferred Stock
so designated shall have, and the Company shall provide, access to the lists of
Holders of Cumulative Convertible Preferred Stock and the holders of such other
series of Preferred Stock for any such meeting of the holders thereof to be
called pursuant to the provisions hereof. If no special meeting of the Holders
of Cumulative Convertible Preferred Stock and the holders of such other series
of Preferred Stock is called as provided in this paragraph 6, then such meeting
shall be deemed to have been called for the next meeting of stockholders of the
Company.

               At any meeting held for the purposes of electing directors at
which the Holders of Cumulative Convertible Preferred Stock (together with the
holders of any other series of Preferred 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 Cumulative Convertible Preferred Stock (and such other series of
Preferred Stock) shall be required to constitute a quorum thereof.

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

               Except as set forth above and otherwise required by applicable
law, the creation, authorization or issuance of any shares of any Junior
Securities, Parity Securities or Senior Securities, or the increase or decrease
in the amount of authorized Capital Stock of any class, including Preferred
Stock, shall not require the affirmative vote or consent of Holders of
Cumulative Convertible Preferred Stock and shall not be deemed to affect
adversely the rights, preferences, privileges or voting rights of shares of
Cumulative Convertible Preferred Stock.

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

               Except as required by law, the Holders of the Cumulative
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.

               7. Conversion Rights. The Cumulative Convertible Preferred Stock
will be convertible at the option of the Holder, into shares of Common Stock at
any time, unless previously redeemed or repurchased, at a conversion rate of
13.748 shares of Common Stock per share of the Cumulative Convertible Preferred
Stock) (as adjusted pursuant to the provisions hereof, the "Conversion Rate")
(subject to the adjustments described below). The right to convert a share of
the Cumulative Convertible Preferred Stock called for redemption or delivered
for repurchase will

                                       -7-

<PAGE>   173



terminate at the close of business on the Redemption Date for such Cumulative
Convertible Preferred Stock or at the time of the repurchase, as the case may
be.

               The right of conversion attaching to any share of Cumulative
Convertible Preferred Stock may be exercised by the Holder thereof by delivering
the share to be converted to the office of the Transfer Agent, or any agency or
office of the Company maintained for that purpose, accompanied by a duly signed
and completed notice of conversion in form reasonably satisfactory to the
Transfer Agent of the Company, such as that which is set forth in Exhibit B
hereto. The conversion date will be the date on which the share and the duly
signed and completed notice of conversion are so delivered. As promptly as
practicable on or after the conversion date, the Company will issue and deliver
to the Transfer Agent a certificate or certificates for the number of full
shares of Common Stock issuable upon conversion, with any fractional shares
rounded up to full shares or, at the Company's option, payment in cash in lieu
of any fraction of a share, based on the Closing Price of the Common Stock on
the Trading Day preceding the conversion date. Such certificate or certificates
will be delivered by the Transfer Agent to the appropriate Holder on a
book-entry basis or by mailing certificates evidencing the additional shares to
the Holders at their respective addresses set forth in the register of Holders
maintained by the Transfer Agent. All shares of Common Stock issuable upon
conversion of the Cumulative Convertible Preferred Stock will be fully paid and
nonassessable and will rank pari passu with the other shares of Common Stock
outstanding from time to time. Any shares of Cumulative Convertible Preferred
Stock surrendered for conversion during the period from the close of business on
any Record Date to the opening of business on the next succeeding Dividend
Payment Date must be accompanied by payment of an amount equal to the dividends
payable on such Dividend Payment Date on the shares of Cumulative Convertible
Preferred Stock being surrendered for conversion. No other payment or adjustment
for dividends, or for any dividends in respect of shares of Common Stock, will
be made upon conversion. Holders of Common Stock issued upon conversion will not
be entitled to receive any dividends payable to holders of Common Stock as of
any record time before the close of business on the conversion date.

               The Conversion Rate shall be adjusted from time to time by the
Company as follows:

                      a. 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 Rate 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
increased by multiplying such Conversion Rate by a fraction of which the
denominator shall be the number of shares of Common Stock outstanding at the
close of business on the Record Date (as defined below) fixed for such
determination and the numerator shall be the sum of such number of outstanding
shares and the total number of shares constituting such dividend or other
distribution, such increase 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 provision (a) is declared but not so paid or made,
the Conversion Rate shall again be adjusted to the Conversion Rate which would
then be in effect if such dividend or distribution had not been declared.

                      b. If the outstanding shares of Common Stock shall be
subdivided into a greater number of shares of Common Stock, the Conversion Rate
in effect at the opening of

                                       -8-

<PAGE>   174



business on the day following the day upon which such subdivision becomes
effective shall be proportionately increased and, conversely, if the outstanding
shares of Common Stock shall be combined into a smaller number of shares of
Common Stock, the Conversion Rate in effect at the opening of business on the
day following the day upon which such combination becomes effective shall be
proportionately reduced, such increase or reduction, 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.

                      c. If the Company shall offer or issue rights, options 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 below) on the Record Date fixed for the
determination of shareholders entitled to receive such rights or warrants, the
Conversion Rate shall be adjusted so that the same shall equal the rate
determined by multiplying the Conversion Rate in effect at the opening of
business on the date after such Record Date by a fraction 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 number of shares of Common Stock
which the aggregate offering price of the total number of shares of Common Stock
subject to such rights, options or warrants would purchase at such Current
Market Price and 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 total
number of additional shares of Common Stock subject to such rights, options 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, options or warrants, upon the expiration or termination
of such rights or warrants the Conversion Rate shall again be adjusted to be the
Conversion Rate 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 Rate shall again be adjusted to be
the Conversion Rate 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.

                      d. 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 to which
provision (a) of this Section 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 (c) of this Section) (the foregoing hereinafter
called the "Distributed Securities"), then, in each such case, the Conversion
Rate shall be increased so that the same shall be equal to the rate determined
by multiplying the Conversion Rate in effect immediately prior to the close of
business on the Record Date (as defined below) with respect to such distribution
by a fraction of which the denominator shall be the Current Market Price
(determined as provided in provision g(ii) of this Section) of the Common Stock
on such date less the Fair Market Value (as

                                       -9-

<PAGE>   175



defined below) on such date of the portion of the Distributed Securities so
distributed applicable to one share of Common Stock and the numerator shall be
such Current Market Price, such increase 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 Cumulative Convertible Preferred Stock shall have the right
to receive upon conversion of a share of Cumulative Convertible Preferred Stock
(or any portion thereof) the amount of Distributed Securities such holder would
have received had such holder converted such share of Cumulative 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 Rate shall
again be adjusted to be the Conversion Rate 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 hereof by
reference to the actual or when issued trading market for any securities
comprising all 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 provision g(ii) of this section 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 provision (d) (and no adjustment to the
Conversion Rate under this provision (d) 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 Rate under this provision (d) 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 Rate under this provision (d) 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 Rate 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 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 Rate shall be readjusted
as if such rights and warrants had not been issued.

                                      -10-

<PAGE>   176



               Notwithstanding any other provision of this provision (d) 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 provision (d) if the Company makes proper
provision so that each Holder of shares of Cumulative Convertible Preferred
Stock who converts a share of Cumulative 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 Cumulative Convertible Preferred Stock into Common Stock.

               For purposes of this provision (d), provision (a) and provision
(b), any dividend or distribution to which this provision (d) is applicable that
also includes Common Stock, or rights or warrants to subscribe for or purchase
Common Stock to which provision (b) 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 provision (b) applies (and
any Conversion Rate increase required by this provision (d) 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 Rate increase required by provisions (a) and (b) with
respect to such dividend or distribution shall then be made), except that (1)
the Record Date of such 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 provision (a) 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
provision (b), 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 provision (a).

                      e. If the Company shall, by dividend or otherwise,
distribute to all holders of its Common Stock cash (excluding any cash that is
part of a distribution referred to in provision (d)) 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 provision (e) 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 provision
(d) has been made, exceeds 10% of the product of the Current Market Price
(determined as provided below) 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 Rate shall be

                                      -11-

<PAGE>   177



increased so that the same shall equal the price determined by multiplying the
Conversion Rate in effect immediately prior to the close of business on such
Record Date by a fraction (i) the denominator 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 10% amount divided by (y) the
number of shares of Common Stock outstanding on the Record Date and (ii) the
numerator 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 Cumulative
Convertible Preferred Stock shall have the right to receive upon conversion of a
share of Cumulative Convertible Preferred Stock (or any portion thereof) the
amount of cash such holder would have received had such holder converted such
share of Cumulative 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 Rate shall again be adjusted to be the Conversion Rate
which would then be in effect if such dividend or distribution had not been
declared.

                      f. 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 that, combined
together with (1) the aggregate of the cash plus the Fair Market Value, 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 provision (f) has been made and (2) the aggregate amount of any
distributions to all holders of 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 provision (e) has been made, exceeds 10% of the
product of the Current Market Price 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 Rate shall be adjusted so that the same shall
equal the price determined by multiplying the Conversion Rate in effect
immediately prior to the close of business on the date of the Expiration Time by
a fraction of which the denominator 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 numerator shall be the sum of (x)
the Fair Market Value 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

                                      -12-

<PAGE>   178



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 Rate shall again be adjusted to be
the Conversion Rate which would then be in effect if such tender offer had not
been made. If the application of this provision (f) to any tender offer would
result in a decrease in the Conversion Rate, no adjustment shall be made for
such tender offer under this provision (f).

               The Company may make voluntary increases in the Conversion Rate
in addition to those required in the foregoing provisions, provided that each
such increase is in effect for at least 20 calendar days.

               In addition, in the event that any other transaction or event
occurs as to which the foregoing Conversion Rate adjustment provisions are not
strictly applicable but the failure to make any adjustment would adversely
affect the conversion rights represented by the Cumulative Convertible Preferred
Stock in accordance with the essential intent and principles of such provisions,
then, in each such case, either (i) the Company will appoint an investment
banking firm of recognized national standing, or any other financial expert that
does not (or whose directors, officers, employees, affiliates or stockholders do
not) have a direct or material indirect financial interest in the Company or any
of its subsidiaries, who has not been, and, at the time it is called upon to
give independent financial advice to the Company, is not (and none of its
directors, officers, employees, affiliates or stockholders are) a promoter,
director or officer of the Company or any of its subsidiaries, which will give
their opinion upon or (ii) the Board of Directors shall, in its sole discretion,
determine consistent with the Board of Directors' fiduciary duties to the
holders of the Company's Common Stock, the adjustment, if any, on a basis
consistent with the essential intent and principles established in the foregoing
Conversion Rate adjustment provisions, necessary to preserve, without dilution,
the conversion rights represented by the Cumulative Convertible Preferred Stock.
Upon receipt of such opinion or determination, the Company will promptly mail a
copy thereof to the Holders of the Cumulative Convertible Preferred Stock and
will, subject to the fiduciary duties of the Board of Directors, make the
adjustments described therein.

               The Company will provide to Holders of the Cumulative Convertible
Preferred Stock reasonable notice of any event that would result in an
adjustment to the Conversion Rate pursuant to this section so as to permit the
Holders to effect a conversion of Cumulative Convertible Preferred Stock into
shares of Common Stock prior to the occurrence of such event.

                      g. For purposes of this section, the following terms shall
have the meaning indicated:

                             i. "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.

                             ii. "Fair Market Value" shall mean the amount which
a willing buyer would pay a willing seller in an arm's-length transaction, under
usual and ordinary circumstances and after consideration of all available uses
and purposes without any compulsion

                                      -13-

<PAGE>   179



upon the seller to sell or the buyer to buy, as determined by the Board of
Directors, whose determination shall be made in good faith and shall be
conclusive and described in a resolution of the Board of Directors.

                             iii. "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).

                      h. No adjustment in the Conversion Rate shall be required
unless such adjustment would require an increase or decrease of at least 1% in
such rate; provided, however, that any adjustments which by reason of this
paragraph are not required to be made shall be carried forward and taken into
account in any subsequent adjustment. All calculations under this paragraph
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.

                      i. Whenever the Conversion Rate is adjusted as herein
provided, the Company shall promptly file with the Transfer Agent an Officers'
Certificate setting forth the Conversion Rate 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 Rate setting forth the adjusted Conversion Rate and
the date on which each adjustment becomes effective and shall mail such notice
of such adjustment of the Conversion Rate to each holder of Cumulative
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.

                      j. In any case in which this paragraph 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 Cumulative 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.

                      k. For purposes of this paragraph, 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.

        8.     Certain Covenants.

               a.     Transactions with Affiliates

                      Without the affirmative vote or consent of the holders of
a majority of the outstanding shares of Cumulative Convertible Preferred Stock,
the Company will not, and will not permit any of its subsidiaries to, make any
payment to, or sell, lease, transfer or otherwise dispose of any of its
properties or assets to, or purchase any property or assets from, or enter into
or make or amend any contract, agreement, understanding, loan, advance or
guarantee with, or for the benefit of, any Affiliate (each of the foregoing, an
"Affiliate Transaction"), unless (i) such Affiliate Transaction is on terms that
are no less favorable to the Company or the relevant subsidiary than those that
would have been obtained in a comparable transaction by the Company or such
subsidiary with an unrelated Person and (ii) the Company files in its minute
books with respect to any Affiliate Transaction or series of related Affiliate
Transaction involving aggregate consideration in excess of $1.0 million, a
resolution of the Board of Directors set forth in an Officers' Certificate
certifying that such Affiliate Transaction complies with clause (i) above and
that such Affiliate Transaction has been approved by a majority of the members
of the Board of Directors that are disinterested as to such Affiliate
Transaction.

                      As used herein, "Affiliate" of any specified Person means
any other Person directly or indirectly controlling or controlled by or under
direct or indirect common control with such specified Person. For purposes of
this definition, "control" (including, with correlative meanings, the terms
"controlling," "controlled by" and "under common control with"), as used with
respect to any Person, shall mean the possession, directly or indirectly, of the
power to direct or cause the direction of the management or policies of such
Person, whether through the ownership of voting securities, by agreement or
otherwise; provided that beneficial ownership of 10% or more of the voting
securities of a Person shall be deemed to be control.

                      The provisions of the foregoing paragraph shall not
prohibit (i) any issuance of securities, or other payments, awards or grants in
cash, securities or otherwise pursuant to, or the funding of, employment
arrangements, stock options and stock ownership plans approved by the Board of
Directors, (ii) the grant of stock options or similar rights to employees and
directors of the Company pursuant to plans approved by the Board of Directors,
(iii) any employment or consulting arrangement or agreement entered into by the
Company or any of its subsidiaries in the ordinary course of business and
consistent with the past practice of the Company or such subsidiary, (iv) the
payment of reasonable fees to directors of the Company and its subsidiaries who
are not employees of the Company or its subsidiaries, (v) any Affiliate
Transaction between the Company and a subsidiary thereof or between such
subsidiaries (for purposes of this paragraph, "subsidiary" includes any entity
deemed to be an Affiliate because the Company or any of its subsidiaries own
securities in such entity or controls such entity), or (vi) transactions between
the Company or any subsidiary thereof specifically contemplated by the PSINet
Agreement dated as of July 22, 1997 between a subsidiary of the Company and
PSINet, as amended as of the date hereof.


                                      -15-

<PAGE>   181



               b.     Payments for Consent

                      The Company nor any of its subsidiaries will, directly or
indirectly, pay or cause to be paid any consideration, whether by way of
dividend or other distribution, fee or otherwise, to any Holder of shares of the
Cumulative Convertible Preferred Stock for or as an inducement to any consent,
waiver or amendment of any of the terms or provisions of the Certificate of
Designations or the Cumulative Convertible Preferred Stock unless such
consideration is offered to be paid and is paid to all Holders of the Cumulative
Convertible Preferred Stock that consent, waive or agree to amend in the time
frame set forth in the solicitation documents relating to such consent, waiver
or agreement.

               c.     Reports

                      Whether or not required by the rules and regulations of
the Commission, so long as any shares of the Cumulative Convertible Preferred
Stock are outstanding, the Company will furnish to the Holders of the Cumulative
Convertible Preferred Stock (i) all quarterly and annual financial information
that would be required to be contained in a filing with the Commission on Forms
10-Q and 10-K if the Company were required to file such Forms, including
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and, with respect to the annual information only, a report thereon
by the Company's certified independent accountants and (ii) all information that
would be required to be contained in a current report on Form 8-K if the Company
were required to file such reports. In the event the Company has filed any such
report with the Commission, it will not be obligated to separately finish the
report to any Holder unless and until such Holder requests a copy of the report.
In addition, whether or not required by the rules and regulations of the
Commission, the Company will file a copy of all such information and reports
with the Commission for public availability (unless the Commission will not
accept such a filing) and make such information available to securities analysts
and prospective investors upon request.

        9.     Merger, Consolidation or Sale of Assets of the Company

               In the event that the Company is party to any Fundamental Change
or transaction (including, without limitation, a merger other than a merger that
does not result in a reclassification, conversion, exchange or cancellation of
Common Stock), consolidation, sale of all or substantially all of the assets of
the Company, recapitalization or reclassification of Common Stock (other than a
change in par value, or from par value to no par value, or from no par value to
par value or as a result of a subdivision or combination of Common Stock) or any
compulsory share exchange (each of the foregoing, including any Fundamental
Change, being referred to as a "Transaction"), the Company will be obligated,
subject to applicable provisions of state law and the restrictions of the
Indenture, either to offer (a "Repurchase Offer") to purchase all of the shares
of Cumulative Convertible Preferred Stock on the date (the "Repurchase Date")
that is 75 days after the date the Company gives notice of the Transaction, at a
price (the "Repurchase Price") equal to $1,000.00 per share of Cumulative
Convertible Preferred Stock, together with an amount equal to accrued and unpaid
dividends on the Cumulative Convertible Preferred Stock through the Repurchase
Date or to adjust the Conversion Rate as described below. If a Repurchase Offer
is made, the Company shall deposit, on or prior to the Repurchase Date, with a
paying agent an amount of money sufficient to

                                      -16-

<PAGE>   182



pay the aggregate Repurchase Price of the Cumulative Convertible Preferred Stock
which is to be paid on the Repurchase Date.

               On or before the 15th day after the Company knows or reasonably
should know that a Transaction has occurred, the Company will be required to
mail to all Holders a notice of the occurrence of such Transaction and whether
or not the documents governing the Company's indebtedness permit at such time a
Repurchase Offer, and, as applicable, either the new Conversion Rate (as
adjusted at the option of the Company) or the date by which the Repurchase Offer
must be accepted, the Repurchase Price for the Cumulative Convertible Preferred
Stock and the procedures which the holder must follow to accept the Repurchase
Offer. To accept the Repurchase Offer, the Holder of a share of Cumulative
Convertible Preferred Stock will be required to deliver, on or before the 10th
day prior to the Repurchase Date, written notice to the Company (or an agent
designated by the Company for such purpose) of the holder's acceptance, together
with the certificates evidencing the Cumulative Convertible Preferred Stock with
respect to which the offer is being accepted, duly endorsed for transfer.

               In the event the Company does not make a Repurchase Offer with
respect to a Transaction and such Transaction results in shares of Common Stock
being converted into the right to receive, or being exchanged for, (i) in the
case of any Transaction other than a Transaction involving a Common Stock
Fundamental Change (as defined below) (and subject to funds being legally
available for such purpose under applicable law at the time of such conversion),
securities, cash or other property, each share of the Cumulative Convertible
Preferred Stock shall thereafter be convertible into the kind and, in the case
of a Transaction which does not involve a Fundamental Change (as defined below),
amount of securities, cash and other property receivable upon the consummation
of such Transaction by a holder of that number of shares of Common Stock into
which a share of the Cumulative Convertible Preferred Stock was convertible
immediately prior to such Transaction, or (ii) in the case of a Transaction
involving a Common Stock Fundamental Change, common stock, each share of the
Cumulative Convertible Preferred Stock shall thereafter be convertible (in the
manner described therein) into common stock of the kind received by holders of
Common Stock (but in each case after giving effect to any adjustment discussed
below relating to a Fundamental Change if such Transaction constitutes a
Fundamental Change), other than as required by Delaware law.

               If any Fundamental Change occurs, then the Conversion Rate in
effect will be adjusted immediately after such Fundamental Change as described
below. In addition, in the event of a Common Stock Fundamental Change, each
share of Cumulative Convertible Preferred Stock shall be convertible solely into
common stock of the kind received by holders of Common Stock as a result of such
Common Stock Fundamental Change.

               The Conversion Rate in the case of any Transaction involving a
Fundamental Change will be adjusted immediately after such Fundamental Change:

                             (i) in the case of a Non-Stock Fundamental Change
(as defined below), the Conversion Rate will thereupon become the higher of (A)
the Conversion Rate in effect immediately prior to such Non-Stock Fundamental
Change, but after giving effect to any other prior

                                      -17-

<PAGE>   183



adjustments effected, and (B) a fraction, the numerator of which is (x) the
redemption rate for one share of the Cumulative Convertible Preferred Stock if
the redemption date were the date of such Non-Stock Fundamental Change (or, for
the period commencing on the first date of original issuance of the Cumulative
Convertible Preferred Stock and through April 1, 1999, and the twelve-month
period commencing April 1, 1999, the product of 106.75% and 106.075%,
respectively), multiplied by $1000 plus (y) the amount of any then-accrued and
unpaid dividends on one share of the Cumulative Convertible Preferred Stock, and
the denominator of which is the greater of the Applicable Price or the then
applicable Reference Market Price; and

                             (ii) in the case of a Common Stock Fundamental
Change, the Conversion Rate in effect immediately prior to such Common Stock
Fundamental Change, but after giving effect to any other prior adjustments
effected, will thereupon be adjusted by multiplying such Conversion Rate by a
fraction of which the denominator will be the Purchaser Stock Price (as defined
below) and the numerator will be the Applicable Price; provided, however, that
in the event of a Common Stock Fundamental Change in which (A) 100% of the value
of the consideration received by a holder of Common Stock is common stock of the
successor, acquirer, or other third party (and cash, if any, is paid only with
respect to any fractional interests in such common stock resulting from such
Common Stock Fundamental Change) and (B) all Common Stock will have been
exchanged for, converted into, or acquired for common stock (and cash with
respect to fractional interests) of the successor, acquirer, or other third
party, the Conversion Rate in effect immediately prior to such Common Stock
Fundamental Change will thereupon be adjusted by multiplying such Conversion
Rate by the number of shares of common stock of the successor, acquirer, or
other third party received by a holder of one share of Common Stock as a result
of such Common Stock Fundamental Change.

               The term "Applicable Price" means (i) in the case of a Non-Stock
Fundamental Change in which the holders of 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 Fundamental Change or any Common Stock
Fundamental Change, the average of the Closing Price (as defined below) for
Common Stock during the ten Trading Days prior to the record date for the
determination of the holders of Common Stock entitled to receive such
securities, cash, or other property in connection with such Non-Stock
Fundamental Change or Common Stock Fundamental Change or, if there is no such
record date, the date upon which the holders of Common Stock shall have the
right to receive such securities, cash, or other property (such record date or
distribution date being hereinafter referred to as the "Entitlement Date") in
each case as adjusted in good faith by the Company to appropriately reflect any
of the events referred to above.

               The term "Common Stock Fundamental Change" means any Fundamental
Change 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 prior to the Entitlement Date has been admitted for listing or
admitted for listing subject to notice of issuance on a national securities
exchange or quoted on the Nasdaq National Market; provided, however, that a
Fundamental Change shall not be a Common Stock Fundamental Change unless either
(i) the Company continues to exist after the occurrence of such Fundamental
Change and the outstanding Cumulative Convertible Preferred

                                      -18-

<PAGE>   184



Stock continues to exist as outstanding Cumulative Convertible Preferred Stock
or (ii) not later than the occurrence of such Fundamental Change, the
outstanding Cumulative Convertible Preferred Stock is converted into or
exchanged for shares of convertible Preferred Stock of an entity succeeding to
the business of the Company or a subsidiary thereof, 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 Cumulative Convertible Preferred Stock.

               The term "Fundamental Change" means the occurrence of any
Transaction or event in connection with a plan pursuant to which all or
substantially all Common Stock shall be exchanged for, converted into, acquired
for, or constitute solely the right to receive securities, cash, or other
property (whether by means of an exchange offer, liquidation, tender offer,
consolidation, merger, combination, reclassification, recapitalization, or
otherwise), provided, that, in the case of a plan involving more than one such
Transaction or event, for purposes of adjustment of the Conversion Rate, such
Fundamental Change shall be deemed to have occurred when substantially all
Common Stock shall be exchanged for, converted into, or acquired for or
constitute solely the right to receive securities, cash, or other property, but
the adjustment shall be based upon the consideration that a holder of Common
Stock received in such Transaction or event as a result of which more than 50%
of Common Stock shall have been exchanged for, converted into, or acquired for
or constitute solely the right to receive securities, cash, or other property.
The term "Non-Stock Fundamental Change" means any Fundamental Change other than
a Common Stock Fundamental Change.

               The term "Purchaser Stock Price" means, with respect to any
Common Stock Fundamental Change, the average of the Closing Prices for the
common stock received in such Common Stock Fundamental Change for the ten
consecutive Trading Days prior to and including the Entitlement Date, as
adjusted in good faith by the Company to appropriately reflect any of the events
referred to above.

               The term "Reference Market Price" shall initially mean $38.79
(which is an amount equal to 66 2/3% of the reported last sales price for Common
Stock on the Nasdaq National Market on March 25, 1998) and in the event of any
adjustment of the Conversion Rate other than as a result of a Non-Stock
Fundamental Change, the Reference Market Price shall also be adjusted so that
the ratio of the Reference Market Price to the Conversion Rate after giving
effect to any such adjustment shall always be the same as the ratio of the
initial Reference Market Price to the initial Conversion Rate.

               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; (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; (3) of any
reclassification of the Common Stock of the Company (other than a subdivision or
combination of its outstanding Common Stock); (4) of any consolidation or merger
to which the Company is a party and for which approval of any shareholders of
the Company is required; (5) the sale or transfer of all or substantially all
the assets of the Company; or (6) of the voluntary or involuntary dissolution,

                                      -19-

<PAGE>   185



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 Cumulative Convertible Preferred Stock, and shall
cause to be mailed to all holders at their last addresses as they shall appear
in the Cumulative 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.

               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 Cumulative
Convertible Preferred Stock, the full number of shares of Common Stock then
issuable upon the conversion of all outstanding shares of Cumulative Convertible
Preferred Stock.

               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 Cumulative 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 Cumulative Convertible Preferred Stock or the shares of Cumulative
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.

               10. Reissuance of Cumulative Convertible Preferred Stock. Shares
of Cumulative Convertible Preferred Stock redeemed for or converted into Common
Stock or that have been reacquired in any manner shall not be reissued as shares
of Cumulative 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 Cumulative Convertible Preferred Stock
are outstanding, any issuance of such shares must be in compliance with the
terms hereof.

               11. 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
Business Day.

               12. Additional Rights of Holders. In addition to the rights
provided to Holders under this Certificate of Designation, Holders shall have
the rights set forth in the Registration Rights Agreement.

               13. Amendment, Supplement and Waiver. The Company may amend this
Certificate of Designation with the affirmative vote or consent of the holders
of a majority of the shares of Cumulative Convertible Preferred Stock then
outstanding, (including votes or consents obtained in connection with a tender
offer or exchange offer for the Cumulative Convertible Preferred Stock) and,
except as otherwise provided by applicable law, any past default or failure to
comply with any provision of this Certificate of Designation may also be waived
with the consent of such holders. Notwithstanding the foregoing, however,
without the consent of each Holder affected, an amendment or waiver may not
(with respect to any shares of the Cumulative Convertible Preferred Stock held
by a non-consenting Holder): (i) alter the voting rights with respect to the
Cumulative Convertible Preferred Stock or reduce the number of shares of the
Cumulative Convertible Preferred Stock whose Holders must consent to an
amendment, supplement or waiver, (ii) reduce the Liquidation Preference of any
share of the Cumulative Convertible Preferred Stock or adversely alter the
provisions with respect to the redemption of the Cumulative Convertible
Preferred Stock, (iii) reduce the rate of or change the time for payment of
dividends on any share of the Cumulative Convertible Preferred Stock, (iv) waive
a default in the payment of dividends or Liquidated Damages (if any) on the
Cumulative Convertible Preferred Stock, (v) make any share of the Cumulative
Convertible Preferred Stock payable in money other than United States dollars,
(vi) make any change in the provisions of the Certificate of Designation
relating to waivers of the rights of Holders of the Cumulative Convertible
Preferred Stock to receive the Liquidation Preference, dividends or Liquidated
Damages (if any) on the Cumulative Convertible Preferred Stock, or (vii) make
any change in the foregoing amendment and waiver provisions.

               Notwithstanding the foregoing, without the consent of any Holder
of the Cumulative Convertible Preferred Stock, the Company may (to the extent
permitted by, and subject to the requirements of, Delaware law) amend or
supplement this Certificate of Designation to cure any ambiguity, defect or
inconsistency, to provide for uncertificated shares of the Cumulative
Convertible Preferred Stock in addition to or in place of certificated shares of
the Cumulative Convertible Preferred Stock, to make any change that would
provide any additional rights or benefits to the Holders of the Cumulative
Convertible Preferred Stock or to make any change that the Board of Directors
determines, in good faith, is not materially adverse to Holders of the
Cumulative Convertible Preferred Stock.

               14. Shelf Registration; Liquidated Damages. Pursuant to the
Registration Rights Agreement, the Company will agree to file a Shelf
Registration Statement with the Commission on the appropriate form under the
Securities Act with respect to the Cumulative Convertible Preferred Stock, any
depositary shares issued in connection with the Cumulative Convertible Preferred
Stock (the "Depositary Shares"), and Common Stock issuable upon conversion
thereof or paid as dividends thereon, to cover resales of the Depositary Shares,
the Cumulative Convertible Preferred Stock or such Common Stock by the Holders
thereof who satisfy certain conditions relating to the provision of information
in connection with the Shelf Registration Statement. The Company will use its
best efforts to cause the Shelf Registration Statement to be declared effective
as promptly as possible by

                                      -21-

<PAGE>   187



the Commission. For purposes hereof, "Transfer Restricted Securities" means each
Depositary Share or share of the Cumulative Convertible Preferred Stock or
Common Stock issuable upon conversion thereof or paid as dividends thereon until
the earlier of (i) the date on which such Depositary Share or share of
Cumulative Convertible Preferred Stock or Common Stock has been effectively
registered under the Securities Act and disposed of in accordance with the Shelf
Registration Statement or (ii) the date on which such Depositary Share or share
of Cumulative Convertible Preferred Stock or Common Stock is eligible to be
distributed to the public pursuant to Rule 144(k) under the Securities Act.

               The Registration Rights Agreement will provide that the Company
will (i) file the Shelf Registration Statement with the Commission on or prior
to 45 days after the Issue Date, (ii) use its best efforts to cause the Shelf
Registration to be declared effective by the Commission on or prior to June 26,
1998 and (iii) use its best efforts to maintain the effectiveness of the Shelf
Registration Statement until all Depositary Shares, shares of Cumulative
Convertible Preferred Stock and shares of Common Stock issued upon conversion
thereof or as dividends thereon that are not held by affiliates of the Company
(A) may be resold without restriction under Rule 144(k) under the Securities Act
or (B) have been sold pursuant to the Shelf Registration Statement (subject to
the Company's right to notify Holders that the Prospectus contained therein
ceases to be accurate and complete as a result of material business developments
for up to 120 days during such three-year period, provided that (A) no single
period may exceed 45 days and (B) such periods in the aggregate may not exceed
60 days in any calendar year). If (a) the Company fails to file the Shelf
Registration Statement required by the Registration Rights Agreement on or
before the date specified for such filing, (b) such Shelf Registration Statement
is not declared effective by the Commission on or prior to the date specified
for such effectiveness (the "Effectiveness Target Date") or (c) the Shelf
Registration Statement is declared effective but thereafter ceases to be
effective or usable in connection with resales of Transfer Restricted Securities
during the periods specified in the Registration Rights Agreement (each such
event referred to in clauses (a) through (c) above a "Registration Default"),
then the Company will pay Liquidated Damages as required by the Registration
Rights Agreement to each Holder of shares of the Cumulative Convertible
Preferred Stock which are Transfer Restricted Securities (and the corresponding
Depositary Shares), with respect to the first 45-day period immediately
following the occurrence of such Registration Default in an amount equal to
$0.25 per year per Depositary Share ($5.00 per year per $1,000 in Liquidation
Preference of the Cumulative Convertible Preferred Stock) held by such Holder.
The amount of the Liquidated Damages will increase by an additional $2.50 per
year per $1,000 in Liquidation Preference of the Cumulative Convertible
Preferred Stock with respect to any subsequent period until all Registration
Defaults have been cured. In addition, holders of shares of the Cumulative
Convertible Preferred Stock which are Transfer Restricted Securities may receive
Liquidated Damages with respect to Common Stock which are Transfer Restricted
Securities issued in lieu of paying dividends in cash. The Liquidated Damages
amount per share of Common Stock will be equal to the Liquidated Damages per
share of Cumulative Convertible Preferred Stock, divided by the Conversion Rate.
All accrued Liquidated Damages will be paid by the Company, to the extent
permitted by applicable law, on each Dividend Payment Date and, to the extent
the net dividend payable on such date may be paid through the issuance of Common
Stock, may be paid in Common Stock (valued on the same basis as for the dividend
then payable). Following the cure of all Registration Defaults, the accrual of
Liquidated Damages will cease. Notwithstanding anything to

                                      -22-

<PAGE>   188



the contrary herein contained, during any period, the Company will not be
required to pay Liquidated Damages with respect to more than one Registration
Default.

Rights Agreement does not purport to be complete and is subject to, and is
qualified in its entirety by reference to, all the provisions of the
Registration Rights Agreement, a copy of which is available upon request to the
Company.

               15. Transfer and Exchange. When Cumulative Convertible Preferred
Stock is presented to the Transfer Agent with a request to register the transfer
of such Cumulative Convertible Preferred Stock or to exchange such Cumulative
Convertible Preferred Stock for an equal number of shares of Cumulative
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 and such transfer or
exchange is in compliance with applicable laws or regulations.

                                       of

                  SERIES A JUNIOR PARTICIPATING PREFERRED STOCK

                                       of

                            IXC COMMUNICATIONS, INC.

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

        IXC Communications, Inc., a corporation organized and existing under the
General Corporation Law of the State of Delaware, in accordance with the
provisions of Section 103 thereof, DOES HEREBY CERTIFY:

        That pursuant to the authority vested in the Board of Directors in
accordance with the provisions of the Certificate of Incorporation of the said
Corporation, the said Board of Directors on September 4, 1998 adopted the
following resolution creating a series of 55,000 shares of Preferred Stock
designated as "Series A Junior Participating Preferred Stock":

               RESOLVED, that pursuant to the authority vested in the Board of
        Directors of this Corporation in accordance with the provisions of the
        Certificate of Incorporation, a series of Preferred Stock, par value
        $.01 per share, of the Corporation be and hereby is created, and that
        the designation and number of shares thereof and the voting and other
        powers, preferences and relative, participating, optional or other
        rights of the shares of such series and the qualifications, limitations
        and restrictions thereof are as follows:

                  SERIES A JUNIOR PARTICIPATING PREFERRED STOCK

        1. Designation and Amount. There shall be a series of Preferred Stock
that shall be designated as "Series A Junior Participating Preferred Stock," and
the number of shares constituting such series shall be 55,000. Such number of
shares may be increased or decreased by resolution of the Board of Directors;
provided, however, that no decrease shall reduce the number of shares of Series
A Junior Participating Preferred Stock to less than the number of shares then
issued and outstanding plus the number of shares issuable upon exercise of
outstanding rights, options or warrants or upon conversion of outstanding
securities issued by the Corporation.


                                       1
<PAGE>   200

        2.     Dividends and Distribution.

               (A) Subject to the prior and superior rights of the holders of
any shares of any class or series of stock of the Corporation ranking prior and
superior to the shares of Series A Junior Participating Preferred Stock with
respect to dividends, the holders of shares of Series A Junior Participating
Preferred Stock, in preference to the holders of shares of any class or series
of stock of the Corporation ranking junior to the Series A Junior Participating
Preferred Stock in respect thereof, shall be entitled to receive, when, as and
if declared by the Board of Directors out of funds legally available for the
purpose, quarterly dividends payable in cash on the 15th day of January, April,
July and October, in each year (each such date being referred to herein as a
"Quarterly Dividend Payment Date"), commencing on the first Quarterly Dividend
Payment Date after the first issuance of a share or fraction of a share of
Series A Junior Participating Preferred Stock, in an amount per share (rounded
to the nearest cent) equal to the greater of (a) $10.00 or (b) the Adjustment
Number (as defined below) times the aggregate per share amount of all cash
dividends, and the Adjustment Number times the aggregate per share amount
(payable in kind) of all non-cash dividends or other distributions other than a
dividend payable in shares of Common Stock or a subdivision of the outstanding
shares of Common Stock (by reclassification or otherwise), declared on the
Common Stock, par value $.01 per share, of the Corporation (the "Common Stock")
since the immediately preceding Quarterly Dividend Payment Date, or, with
respect to the first Quarterly Dividend Payment Date, since the first issuance
of any share or fraction of a share of Series A Junior Participating Preferred
Stock. The "Adjustment Number" shall initially be 1000. In the event the
Corporation shall at any time after September 20, 1998 (i) declare and pay any
dividend on Common Stock payable in shares of Common Stock, (ii) subdivide the
outstanding Common Stock or (iii) combine the outstanding Common Stock into a
smaller number of shares, then in each such case the Adjustment Number in effect
immediately prior to such event shall be adjusted by multiplying such Adjustment
Number by a fraction the numerator of which is the number of shares of Common
Stock outstanding immediately after such event and the denominator of which is
the number of shares of Common Stock that were outstanding immediately prior to
such event.

               (B) The Corporation shall declare a dividend or distribution on
the Series A Junior Participating Preferred Stock as provided in paragraph (A)
above immediately after it declares a dividend or distribution on the Common
Stock (other than a dividend payable in shares of Common Stock).

               (C) Dividends shall begin to accrue and be cumulative on
outstanding shares of Series A Junior Participating Preferred Stock from the
Quarterly Dividend Payment Date next preceding the date of issue of such shares
of Series A Junior Participating Preferred Stock, unless the date of issue of
such shares is prior to the record date for the first Quarterly Dividend Payment
Date, in which case dividends on such shares shall begin to accrue from the date
of issue of such shares, or unless the date of issue is a Quarterly Dividend
Payment Date or is a date after the record date for the determination of holders
of shares of Series A Junior Participating Preferred Stock entitled to receive a
quarterly dividend and before such Quarterly Dividend Payment Date, in either of
which events such dividends shall begin to accrue and be cumulative from such
Quarterly Dividend Payment 


                                       2
<PAGE>   201

Date. Accrued but unpaid dividends shall not bear interest. Dividends paid on
the shares of Series A Junior Participating Preferred Stock in an amount less
than the total amount of such dividends at the time accrued and payable on such
shares shall be allocated pro rata on a share-by-share basis among all such
shares at the time outstanding. The Board of Directors may fix a record date for
the determination of holders of shares of Series A Junior Participating
Preferred Stock entitled to receive payment of a dividend or distribution
declared thereon, which record date shall be no more than 60 days prior to the
date fixed for the payment thereof.

        3. Voting Rights. The holders of shares of Series A Junior Participating
Preferred Stock shall have the following voting rights:

               (A) Each share of Series A Junior Participating Preferred Stock
shall entitle the holder thereof to a number of votes equal to the Adjustment
Number on all matters submitted to a vote of the stockholders of the
Corporation.

               (B) Except as required by law, by Section 3(C) and by Section 10
hereof, holders of Series A Junior Participating Preferred Stock shall have no
special voting rights and their consent shall not be required (except to the
extent they are entitled to vote with holders of Common Stock as set forth
herein) for taking any corporate action.

               (C) If, at the time of any annual meeting of stockholders for the
election of directors, the equivalent of six quarterly dividends (whether or not
consecutive) payable on any share or shares of Series A Junior Participating
Preferred Stock are in default, the number of directors constituting the Board
of Directors of the Company shall be increased by two. In addition to voting
together with the holders of Common Stock for the election of other directors of
the Company, the holders of record of the Series A Junior Participating
Preferred Stock, voting separately as a class to the exclusion of the holders of
Common Stock, shall be entitled at said meeting of stockholders (and at each
subsequent annual meeting of stockholders), unless all dividends in arrears on
the Series A Junior Participating Preferred Stock have been paid or declared and
set apart for payment prior thereto, to vote for the election of two directors
of the Company, the holders of any Series A Junior Participating Preferred Stock
being entitled to cast a number of votes per share of Series A Junior
Participating Preferred Stock as is specified in paragraph (A) of this Section
3. Until the default in payments of all dividends which permitted the election
of said directors shall cease to exist, any director who shall have been so
elected pursuant to the next preceding sentence may be removed at any time,
without cause, only by the affirmative vote of the holders of the shares of
Series A Junior Participating Preferred Stock at the time entitled to cast a
majority of the votes entitled to be cast for the election of any such director
at a special meeting of such holders called for that purpose, and any vacancy
thereby created may be filled by the vote of such holders. If and when such
default shall cease to exist, the holders of the Series A Junior Participating
Preferred Stock shall be divested of the foregoing special voting rights,
subject to revesting in the event of each and every subsequent like default in
payments of dividends. Upon the termination of the foregoing special voting
rights, the terms of office of all persons who may have been elected directors
pursuant to said special voting rights shall forthwith terminate, and the number
of directors constituting the Board of Directors shall 


                                       3
<PAGE>   202

be reduced by two. The voting rights granted by this Section 3(c) shall be in
addition to any other voting rights granted to the holders of the Series A
Junior Participating Preferred Stock in this Section 3.

        4.     Certain Restrictions.

               (A) Whenever quarterly dividends or other dividends or
distributions payable on the Series A Junior Participating Preferred Stock as
provided in Section 2 are in arrears, thereafter and until all accrued and
unpaid dividends and distributions, whether or not declared, on shares of Series
A Junior Participating Preferred Stock outstanding shall have been paid in full,
the Corporation shall not:

                      (i) declare or pay dividends on, make any other
distributions on, or redeem or purchase or otherwise acquire for consideration
any shares of stock ranking junior (either as to dividends or upon liquidation,
dissolution or winding up) to the Series A Junior Participating Preferred Stock;

                      (ii)   declare or pay dividends on or make any other
distributions on any shares of stock ranking on a parity (either as to dividends
or upon liquidation, dissolution or winding up) with the Series A Junior
Participating Preferred Stock, except dividends paid ratably on the Series A
Junior Participating Preferred Stock and all such parity stock on which
dividends are payable or in arrears in proportion to the total amounts to which
the holders of all such shares are then entitled; or

                      (iii) purchase or otherwise acquire for consideration any
shares of Series A Junior Participating Preferred Stock, or any shares of stock
ranking on a parity with the Series A Junior Participating Preferred Stock,
except in accordance with a purchase offer made in writing or by publication (as
determined by the Board of Directors) to all holders of Series A Junior
Participating Preferred Stock, or to such holders and holders of any such shares
ranking on a parity therewith, upon such terms as the Board of Directors, after
consideration of the respective annual dividend rates and other relative rights
and preferences of the respective series and classes, shall determine in good
faith will result in fair and equitable treatment among the respective series or
classes.

               (B) The Corporation shall not permit any subsidiary of the
Corporation to purchase or otherwise acquire for consideration any shares of
stock of the Corporation unless the Corporation could, under paragraph (A) of
this Section 4, purchase or otherwise acquire such shares at such time and in
such manner.

               5. Reacquired Shares. Any shares of Series A Junior Participating
Preferred Stock purchased or otherwise acquired by the Corporation in any manner
whatsoever shall be retired promptly after the acquisition thereof. All such
shares shall upon their retirement become authorized but unissued shares of
Preferred Stock and may be reissued as part of a new series of Preferred 


                                       4
<PAGE>   203

Stock to be created by resolution or resolutions of the Board of Directors,
subject to any conditions and restrictions on issuance set forth herein.

               6. Liquidation, Dissolution or Winding Up. (A) Upon any
liquidation, dissolution or winding up of the Corporation, voluntary or
otherwise, no distribution shall be made to the holders of shares of stock
ranking junior (either as to dividends or upon liquidation, dissolution or
winding up) to the Series A Junior Participating Preferred Stock unless, prior
thereto, the holders of shares of Series A Junior Participating Preferred Stock
shall have received an amount per share (the "Series A Liquidation Preference")
equal to the greater of (i) $10.00 plus an amount equal to accrued and unpaid
dividends and distributions thereon, whether or not declared, to the date of
such payment, or (ii) the Adjustment Number times the per share amount of all
cash and other property to be distributed in respect of the Common Stock upon
such liquidation, dissolution or winding up of the Corporation.

                      (B) In the event, however, that there are not sufficient
assets available to permit payment in full of the Series A Liquidation
Preference and the liquidation preferences of all other classes and series of
stock of the Corporation, if any, that rank on a parity with the Series A Junior
Participating Preferred Stock in respect thereof, then the assets available for
such distribution shall be distributed ratably to the holders of the Series A
Junior Participating Preferred Stock and the holders of such parity shares in
proportion to their respective liquidation preferences.

                      (C) Neither the merger or consolidation of the Corporation
into or with another corporation nor the merger or consolidation of any other
corporation into or with the Corporation shall be deemed to be a liquidation,
dissolution or winding up of the Corporation within the meaning of this Section
6.

               7. Consolidation, Merger, Etc. In case the Corporation shall
enter into any consolidation, merger, combination or other transaction in which
the outstanding shares of Common Stock are exchanged for or changed into other
stock or securities, cash and/or any other property, then in any such case each
share of Series A Junior Participating Preferred Stock shall at the same time be
similarly exchanged or changed in an amount per share equal to the Adjustment
Number times the aggregate amount of stock, securities, cash and/or any other
property (payable in kind), as the case may be, into which or for which each
share of Common Stock is changed or exchanged.

               8. No Redemption. Shares of Series A Junior Participating
Preferred Stock shall not be subject to redemption by the Company.

                        (iii) In the case of an individual who ceases to be an

                 (b) In the case of any individual whose Participation
         Commencement Date does not coincide with the Annual Stockholders'
         Meeting, the Participant's Fixed Credit will be reduced by multiplying
         it by a fraction, the numerator of which is (i) the number of days
         between the Participation Commencement Date and the date one year after
         the most recent Annual Stockholders' Meeting and the denominator of

         Stock on the individual's Participation Commencement Date.

                 (b) If the Company pays cash dividends on its shares of Common
         Stock, each Participant's Account shall be credited with a deemed
         dividend payment on the shares credited to the Participant's Account
         using the dividend per share amount established by the Company.

                 (c) Any cash dividends that are deemed to be paid on the shares
         of Common Stock held in a Participant's Account will be deemed to be
         used to purchase additional whole and partial shares of Common Stock.
         The Fair Market Value of the Common Stock for this purpose will be
         determined pursuant to Section 3(k)(ii) above as of the date on which
         the dividends are paid.

         9. VESTING.

                 (a) Each Participant shall earn a vested right to the amount of
         shares deemed to be credited to the Participant's Account for a Class
         Year on a monthly basis, over the remaining term of the Class Year,
         starting on the individual's Participation Commencement Date.

                 (b) A Participant will cease vesting in the shares deemed to be
         credited to the Participant's Account for a Class Year if the
         Participant becomes an Inside Director, so that the Participant will
         forfeit the nonvested portion of the Participant's Account attributable
         to that Class Year as of the date the Participant becomes an Inside
         Director.

                 (c) If a Participant ceases serving as a Director prior to the
         last day of a Class Year for a reason other than death or Disability,
         the Participant will forfeit the nonvested portion of the Participant's
         Account attributable to that Class Year on the date the Participant
         ceases to serve as a Director. If the cessation is caused by the
         Participant's death or Disability, the Participant's interest in the
         Participant's Account will become fully vested on the date of the
         Participant's death or Disability.

                 (d) Any additional shares of Common Stock deemed to be acquired
         during the Class Year (e.g., as a result of cash or stock dividends
         paid on Common Stock) shall be subject to the vesting rules of this
         Section 9, treating such additional shares as if they had been acquired
         on the individual's Participation Commencement Date of the applicable
         Class Year.

         10. TIMING OF BENEFIT PAYMENTS.

                 (a) The entire vested amount in a Participant's Account
         attributable to a Class Year shall be paid to the Participant as soon
         as reasonably practicable following the third Annual Stockholders'
         Meeting that occurs after the individual's Participation Commencement
         Date based on the Fair Market Value of the Common Stock as determined
         pursuant to Section 3(k)(ii) above. Notwithstanding the foregoing, if a
         Participant elects to receive any


                                      - 6 -
<PAGE>   7

         or all of its benefits for a Class Year in the form of Common Stock,
         then such Common Stock shall be issued to the Participant as soon as
         reasonably practicable following the end of the Class Year or at such
         earlier time when the Participant becomes fully vested in such Common
         Stock.

                 (b) In the event that the Participant dies or becomes Disabled
         before the date specified in Paragraph (a) above, the entire amount of
         the Participant's benefit under the Plan (i.e., the amount attributable
         to all Class Years) will be paid as soon as reasonably practicable
         after that date, but in no event later than ninety (90) days after that
         date, based on the Fair Market Value of the Common Stock on the date of
         the Participant's death or Disability (whichever is applicable) as
         determined pursuant to Section 3(k)(ii) above.

                 (c) Except as provided in Paragraph (b) above or in Section 12
         below, no benefits will be payable at the time of termination of a
         Participant's status as a Director, but, rather, the Participant's
         benefit will be paid solely in accordance with Paragraph (a) above.

         11. FORM OF BENEFIT PAYMENTS.

                 (a) Benefits will be paid in the form of a lump sum
         distribution of cash equal to the Fair Market Value of the Common Stock
         deemed to be held in the Participant's Account on the date of the event
         on which the amount of the benefit is to be determined.

                 (b) Notwithstanding the foregoing, effective for Class Years
         beginning after July 31, 1998, a Participant may elect to have all or
         any portion of its benefits associated with a particular Class Year
         payable in the form of Common Stock in accordance with such rules and
         procedures as the Committee may prescribe. This election, once made, is
         irrevocable. Any fractional shares associated with any benefits paid in
         the form of Common Stock will be rounded to the nearest whole number of
         shares.

                 (c) Any Participant who has an account balance on July 31, 1998
         may take a one-time election in accordance with such rules and
         procedures as the Committee may prescribe, no later than December 31,
         1998, that all or any portion of the amounts in the Participant's
         Account (including amounts attributable to prior Class Years) be paid
         in the form of Common Stock. This election, once made, is irrevocable.
         To the extent the shares were vested at the time the election was made,
         those shares will be distributed as soon as reasonably practicable
         following December 31, 1998. To the extent that the shares were not
         vested, they will be distributed as soon as reasonably practicable
         following vesting.

         12. EFFECT OF CHANGE IN CONTROL.

                 (a) Notwithstanding anything in this Plan to the contrary, upon
         a Change in Control:


                                      - 7 -
<PAGE>   8

                        (i) All Accounts shall become fully vested as of that
                 date; and

                        (ii) All benefits under the Plan shall become payable as
                 soon after that date as is reasonably practicable, but in no
                 event later than ten (10) business days after that event.

                 (b) If the Participant had not previously elected that some or
         all of his or her benefit be paid in the form of Common Stock, the
         benefit will be paid in the form of cash. To the extent that the
         Participant had elected that his or her benefit be paid in the form of
         Common Stock, the benefit will be paid in the form of consideration
         paid for the Common Stock in the transaction.

         13. DESIGNATION OF BENEFICIARY. In the event of the death of a
Participant prior to the date on which the Participant's entire benefit under
the Plan is paid, the benefit (or the remaining portion thereof) shall be paid
to the Participant's estate, unless the Participant has designated a beneficiary
in accordance with such rules and procedures as the Committee may prescribe.

         14. PAYEES UNDER A LEGAL DISABILITY. If any payee is a minor, or if the
Committee reasonably believes that any payee is legally incapable of giving a
valid receipt and discharge for any payment due the payee, the Committee may
have the payment made to the person (or persons or institution) whom it believes
is caring for or supporting the payee. Any such payment shall be a payment for
the benefit of the payee and shall be a complete discharge of any liability
under the Plan to the payee.

         15. PAYMENT OF BENEFITS. All payments under the Plan shall be delivered
in person or mailed to the last address of the Participant (or, in the case of
the death of the Participant, to that of the Participant's estate or of the
Participant's designated beneficiary, whichever is applicable). Each Participant
shall be responsible for furnishing the Committee with his or her current
address and that of his or her beneficiary (if applicable).

         16. CHANGES IN CAPITALIZATION. In the event of any change in the
capitalization of the Company affecting its Common Stock (e.g., a stock split,
reverse stock split, stock dividend, recapitalization, combination, or
reclassification), the Committee shall make such adjustments as it may deem
appropriate to the aggregate number of shares of Common Stock deemed to be held
in Participants' Accounts.

         17. NON-TRANSFERABILITY OF GRANTS. Benefits under this Plan are not
assignable or transferable except by will or the laws of descent and
distribution.

         18. FUNDED STATUS OF BENEFITS.

                 (a) The Plan is intended to be an unfunded deferred
         compensation arrangement, with the benefits payable, when due, by the
         Company out of its general assets.


                                      - 8 -
<PAGE>   9

                 (b) All rights created under the Plan shall be mere unsecured
         contractual rights of Participants against the Company.

                 (c) Nothing in this Plan shall in any way diminish any rights
         of a Participant to pursue his or her rights as a general creditor of
         Company with respect to his or her benefits under the Plan.

         19. AMENDMENT AND TERMINATION. The Board may amend or terminate this
Plan at any time.

         20. NO ADDITIONAL RIGHTS.

                 (a) Neither the adoption of this Plan nor the participation of
         any Outside Director in this Plan shall:

                        (i) Affect or restrict in any way the power of the
                 Company to undertake any corporate action otherwise permitted
                 under applicable law; or

                        (ii) Confer upon any Participant the right to continue
                 performing services for the Company as a Director, nor shall it
                 interfere in any way with the right of the Stockholders to
                 terminate the services of any Participant as a Director at any
                 time, with or without cause.

                 (b) No Participant shall have any rights as a stockholder with
         respect to any shares of Common Stock payable pursuant to the terms of
         this Plan until the date a certificate for such shares has been issued
         to the Participant.

         21. SECURITIES LAW RESTRICTIONS. No shares of Common Stock shall be
issued under this Plan unless the Company shall be satisfied that the issuance
will be in compliance with applicable federal and state securities laws, as well
as the rules of any stock exchange (or other securities market) on which the
Common Stock is traded.

         22. INDEMNIFICATION. To the maximum extent permitted by law, the
Company shall indemnify each member of the Board, as well as any other employee
of the Company with duties under this Plan, against any and all liabilities and
expenses (including any amount paid in judgment or settlement) reasonably
incurred by the individual in connection with any claims against the individual
by reason of the performance of the individual's duties under this Plan, unless
the losses are due to the individual's gross negligence or lack of good faith.

        shall be determined as of the last preceding day on which the Common

        exercisability of an Incentive Stock Option, a Participant who is on a
        leave of absence that exceeds ninety (90) days will be considered to
        have incurred a Severance on the ninety-first (91st) day of the leave of
        absence, unless the Participant's rights to reemployment are guaranteed
        by statute or contract. However, a Participant will not be considered to
        have incurred a Severance because of a transfer of employment between
        the Company and a Subsidiary or Parent (or vice versa).

                (r) "Subsidiary" means any corporation or entity in which IXC
        Communications, Inc., directly or indirectly, controls fifty percent

        3. ADMINISTRATION.

               (a) This Plan shall be administered by a Committee appointed by
        the Board; provided, however, that the Board may administer the Plan for
        any grants to Participants who are not subject to Code Section 162(m).
        The Board may remove members from, or add members to, the Committee at
        any time. To the extent possible and advisable, the Committee shall be
        composed of individuals that satisfy Rule 16b-3 under the Exchange Act
        and Code Section 162(m). Notwithstanding anything herein to the
        contrary, any action which may be taken by the Committee may also be
        taken by the Board.

               (b) The Committee may conduct its meetings in person or by
        telephone. A majority of the members of the Committee shall constitute a
        quorum, and any action shall constitute the action of the Committee if
        it is authorized by:

                        (i) A majority of the members present at any meeting
                conducted in accordance with the Company's bylaws; or

                        (ii) The unanimous consent of all of the members in
                writing without a meeting.

<PAGE>   4

                (c) The Committee is authorized to interpret this Plan and to
        adopt rules and procedures relating to the administration of this Plan.
        All actions of the Committee in connection with the interpretation and
        administration of this Plan shall be binding upon all parties.

                (d) Subject to the limitations of Sections 10 and 14 of this
        Plan, the Committee is expressly authorized to make such modifications
        to this Plan and to the grants of Options and Restricted Stock hereunder
        as are necessary to effectuate the intent of this Plan as a result of
        any changes in the tax, accounting, or securities laws treatment of
        Participants, the Company and the Plan.

                (e) The Committee may delegate its responsibilities to others
        under such conditions and limitations as it may prescribe, except that
        the Committee may not delegate its authority with regard to the granting
        of Options or Restricted Stock to Insiders if that would cause such
        grants to fail to satisfy Rule 16b-3 under the Exchange Act or Code
        Section 162(m).

        4. DURATION OF PLAN.

                (a) This Plan shall be effective as of July 30, 1998, provided
        it is approved by the majority of the Company's shareholders, in
        accordance with the provisions of Code Section 422, within twelve (12)
        months before or after the date of its adoption by the Board.

                (b) In the event that this Plan is not so approved, this Plan
        shall terminate and any Options granted under this Plan shall be void.

                (c) This Plan shall terminate on July 29, 2008, except with
        respect to Options then outstanding.

        5. NUMBER OF SHARES.

                (a) The aggregate number of shares of Common Stock which may be
        issued pursuant to this Plan shall be Three Million One Hundred Fifty
        Thousand (3,150,000). The maximum number of shares that may be issued to
        a single Participant is Two Hundred Thousand (200,000).

                (b) Upon the expiration or termination of an outstanding Option
        which shall not have been exercised in full, the shares of Common Stock
        remaining unissued under the Option shall again become available for use
        under the Plan.

                (c) Upon the forfeiture of shares of Restricted Stock, the
        forfeited shares of Common Stock shall again become available for use
        under the Plan.

        6. ELIGIBILITY.

                (a) Persons eligible for Options under this Plan shall consist
        of employees, directors, and other persons providing services to the
        Company. However, Incentive Stock Options may only be granted to
        employees.

                (b) Notwithstanding anything in this Plan to the contrary, in
        the event that the Company acquires another entity, the Committee may
        authorize the issuance of Options ("Substitute Options") to individuals
        or entities in substitution of stock options previously granted to those
        individuals or entities in connection with their performance of services
        for such acquired entity upon such terms and conditions as the Committee
        shall determine but which shall not be contrary to applicable law,
        taking into account the limitations of Code Section 424(a) in the case
        of a Substitute Option that is intended to be an Incentive Stock Option.

        7. FORM OF OPTIONS.

                (a) Options shall be granted under this Plan on such terms and
        in such form as the Committee may approve, which shall not be
        inconsistent with the provisions of this Plan; provided, however, that
        in the event a grant of any Options by the Committee would not be exempt
        under Section 16b-3 of the Exchange Act, the Board may grant such
        Options under this Plan on such terms and in such form as the Board may
        approve, which shall not be otherwise inconsistent with the provisions
        of this Plan.

                (b) The exercise price per share of Common Stock purchasable
        under an Option shall be set forth in the Option, which in all cases
        shall be at least equal to the Fair Market Value of the Common Stock on
        the date of the grant.

                (c) The exercise price of an Incentive Stock Option granted to a
        Ten Percent Shareholder shall be no less than one hundred ten percent
        (110%) of the Fair Market Value of the Common Stock on the date of the
        grant.

        8. EXERCISE OF OPTIONS.

                (a) Unless otherwise determined by the Board or the Committee,
        each Option shall be exercisable in four equal annual installments to
        begin in most instances with the start date of a Participant's
        employment with the Company and be subject to such other terms and
        conditions as may be set forth in the Option. Any Option shall be
        exercisable following the date of the Participant's Severance only to
        the extent (if at all) such Option was exercisable on the date of
        Severance.

                (b) The aggregate Fair Market Value (determined as of the date
        of grant) of the number of shares of Common Stock with respect to which
        Incentive Stock Options are exercisable for the first time by a
        Participant during any calendar year shall not exceed one


                                      -5-

<PAGE>   6

        hundred thousand dollars ($100,000) or such other limit as may be
        required by Section 422 of the Code. To the extent this limit is
        exceeded, the surplus shares shall be treated as acquired upon the
        exercise of a Non-Qualified Stock Option. For this purpose, the shares
        will be taken into account in the order in which the underlying Options
        were granted.

                (c) Options shall only be exercisable for whole numbers of
        shares.

                (d) Options are exercised by payment of the full amount of the
        purchase price to the Company.

                        (i) The payment shall be in the form of cash or such
                other forms of consideration as the Committee shall deem
                acceptable, such as the surrender of outstanding shares of
                Common Stock owned by the Participant (that have been held a
                sufficient period of time (if any) to avoid adverse accounting
                treatment) or by withholding shares that would otherwise be
                issued upon the exercise of the Option.

                        (ii) If the payment is made by means of the surrender of
                Restricted Stock, a number of shares issued upon the exercise of
                the Option equal to the number of shares of Restricted Stock
                surrendered shall be subject to the same restrictions as the
                Restricted Stock that was surrendered.

                        (iii) After giving due considerations to the
                consequences under Rule 16b-3 under the Exchange Act and under
                the Code, the Committee may also authorize the exercise of
                Options by the delivery to the Company or its designated agent
                of an irrevocable written notice of exercise form together with
                irrevocable instructions to a broker-dealer to sell or margin a
                sufficient portion of the shares of Common Stock and to deliver
                the sale or margin loan proceeds directly to the Company to pay
                the exercise price of the Option.

        9. RESTRICTED STOCK.

                (a) The Committee may issue grants of Restricted Stock upon such
        terms and conditions as it may deem appropriate, which need not be the
        same for each such grant.

                (b) Restricted Stock may not be sold to Participants for less
        than Fair Market Value.

                (c) A Participant shall not have a vested right to the shares
        subject to the grant of Restricted Stock until satisfaction of the
        vesting requirements specified in the grant. The Participant may not
        assign or alienate the Participant's interest in the shares of
        Restricted Stock prior to vesting.

                (d) The following rules apply with respect to events that occur
        prior to the date on which the Participant obtains a vested right to the
        Restricted Stock.


                                       -6-

<PAGE>   7

                        (i) Stock dividends, shares resulting from stock splits,
                etc. that are issued with respect to the shares covered by a
                grant of Restricted Stock shall be treated as additional shares
                received under the grant of Restricted Stock.

                        (ii) Cash dividends constitute taxable compensation to
                the Participant that is deductible by the Company.

        10. MODIFICATION OF GRANTS.

                (a) The Committee may modify an existing Option, including the
        right to:

                        (i) Accelerate the right to exercise it;

                        (ii) Extend or renew it; or

                        (iii) Cancel it and issue a new Option.

        However, no modification may be made to an Option that would impair the
        rights of the Participant holding the Option without the Participant's
        consent. Similar modifications can be made to grants of Restricted
        Stock.

                (b) Whether a modification of an existing Incentive Stock Option
        will be treated as the issuance of a new Incentive Stock Option will be
        determined in accordance with the rules of Code Section 424(h).

                (c) Whether a modification of an existing grant of Restricted
        Stock or of an Option granted to an Insider will be treated as a new
        grant will be determined in accordance with Rule 16b-3 under the
        Exchange Act.

        11. TERMINATION OF OPTIONS.

                (a) Except to the extent the terms of an Option require its
        prior termination, each Option shall terminate on the earliest of the
        following dates.

                        (i) The date which is ten (10) years from the date on
                which the Option is granted or five (5) years in the case of an
                Incentive Stock Option granted to a Ten Percent Shareholder.

                        (ii) The date which is one (1) year from the date of the
                Severance of the Participant to whom the Option was granted, if
                the Participant was Disabled at the time of Severance.

                        (iii) The date which is one (1) year from the date of
                the Severance of the Participant to whom the Option was granted,
                if the Participant's death occurs:


                                       -7-

<PAGE>   8

                                (A) While the Participant is employed by the
                        Company; or

                                (B) Within three (3) months following the
                        Participant's Severance.

                        (iv) In the case of any Severance other than one
                described in Subparagraphs (ii) or (iii) above, the date that is
                three (3) months from the date of the Participant's Severance.

        12. NON-TRANSFERABILITY OF GRANTS.

                (a) No Option under this Plan shall be assignable or
        transferable except by will or the laws of descent and distribution.

                (b) Grants of Restricted Stock shall be subject to such
        restrictions on transferability as may be imposed in such grants.

        13. ADJUSTMENTS

                (a) In the event of any change in the capitalization of the
        Company affecting its Common Stock (e.g., a stock split, reverse stock
        split, stock dividend, recapitalization, combination, or
        reclassification), the Committee shall authorize such adjustments as it
        may deem appropriate with respect to:

                        (i) The maximum number of shares of Common Stock that
                may be issued under this Plan;

                        (ii) The number of shares of Common Stock covered by
                each outstanding Option;

                        (iii) The exercise price per share in respect of each
                outstanding Option; and

                        (iv) The maximum number of shares that may be issued to
                a single individual.

                (b) The Committee may also make such adjustments in the event of
        a spin-off or other distribution of Company assets to shareholders,
        other than normal cash dividends.

        14. AMENDMENT AND TERMINATION.

                (a) The Board may at any time amend or terminate this Plan.
        However, no modification may be made to the Plan that would impair the
        rights of the Participant holding an Option without the Participant's
        consent.

                (b) Without the approval of the majority of the shareholders of
        the Company, the Board may not amend the provisions of this Plan
        regarding:

                        (i) The class of individuals entitled to receive
                Incentive Stock Options; or

                        (ii) The maximum number of shares of Common Stock that
                may be issued under the Plan, except as provided in Section 13
                of this Plan.

        15. NOTICE OF DISQUALIFYING DISPOSITION. A Participant must notify the
Company if the Participant disposes of stock acquired pursuant to the exercise
of an Incentive Stock Option issued under the Plan prior to the expiration of
the holding periods required to qualify for long-term capital gains treatment on
the disposition.

        16. TAX WITHHOLDING.

                (a) The Company shall have the right to take such actions as may
        be necessary to satisfy its tax withholding obligations relating to the
        operation of this Plan.

                (b) If Common Stock that was surrendered by the Participant is
        used to satisfy the Company's tax withholding obligations, the stock
        shall be valued based on its Fair Market Value when the tax withholding
        is required to be made.

        17. NO ADDITIONAL RIGHTS.

                (a) Neither the adoption of this Plan nor the granting (or
        exercise) of any Option or Restricted Stock shall:

                        (i) Affect or restrict in any way the power of the
                Company to undertake any corporate action otherwise permitted
                under applicable law; or

                        (ii) Confer upon any Participant the right to continue
                performing services for the Company, nor shall it interfere in
                any way with the right of the Company to terminate the services
                of any Participant at any time, with or without cause.

                (b) No Participant shall have any rights as a shareholder with
        respect to any shares covered by an Option granted to the Participant or
        subject to a grant of Restricted Stock until the date a certificate for
        such shares has been issued to the Participant.

        18. SECURITIES LAW RESTRICTIONS.

                (a) No shares of Common Stock shall be issued under this Plan
        unless the Committee shall be satisfied that the issuance will be in
        compliance with applicable federal and state securities laws.


                                       -9-

<PAGE>   10

                (b) The Committee may require certain investment (or other)
        representations and undertakings by the Participant (or other person

        death of the Participant) in order to comply with applicable law.

                (c) Certificates for shares of Common Stock delivered under this
        Plan may be subject to such restrictions as the Committee may deem

shall indemnify each member of the Board, as well as any other employee of the
Company with duties under this Plan, against expenses (including any amount paid
in settlement) reasonably incurred by the individual in connection with any
claims against him or her by reason of the performance of the individual's
duties under this Plan, unless the losses are due to the individual's gross
negligence or lack of good faith.

        20. GOVERNING LAW. This Plan and all actions taken thereunder shall be
governed by and construed in accordance with the laws of the State of Delaware.
