ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS.

     On February 17, 1999, MindSpring Enterprises, Inc., a Delaware corporation
("MindSpring"), acquired some of the tangible and intangible assets and rights 
used in connection with the Internet services business operated in the United 
States by NETCOM On-Line Communication Services, Inc. ("NETCOM"), a Delaware
corporation and an indirect wholly owned subsidiary of ICG Communications, Inc.
(the "Business"), including (1) approximately 400,000 of NETCOM's individual
Internet access accounts; (2) approximately 3,000 dedicated Internet access
accounts; (3) approximately 18,000 Web hosting accounts; (4) leased operations
facilities in San Jose, California and Dallas, Texas; (5) some of NETCOM's
contracts with original equipment manufacturers; (6) NETCOM's rights to the
"NETCOM" name (except in Brazil, Canada and the United Kingdom); (7) some of
NETCOM's intellectual property held or used in connection with the Business;
(8) all engineering, business and other books, papers, files and records
directly related to the Business; (9) all manufacturer's warranties with
respect to the assets being acquired, if any, to the extent assignable; and
(10) some of the other tangible assets such as computers and furniture held or
used by NETCOM in connection with the Business (collectively, the "Assets").
MindSpring and NETCOM entered into an Asset Purchase Agreement (the "Asset
Purchase Agreement") dated January 5, 1999 and amended February 17, 1999
related to the acquisition.  The acquisition will be accounted for under the
purchase method of accounting. The Business is headquartered in San Jose,
California, and has a network operations facility in Dallas, Texas. MindSpring
is currently evaluating the feasibility of consolidating operations and
administration. Otherwise, MindSpring intends to use the Assets in a manner
similar to the manner in which NETCOM used the Assets.

     The NETCOM operations outside the United States are not included in this
transaction. In addition, NETCOM will retain all of the assets used in
connection with its network operations. Under a separate network services
agreement, NETCOM (which will change its name in the near future) will sell
MindSpring access to its network. The agreement has a term of one year with an 
option for a second year on potentially different terms to be negotiated and 
accepted by both parties.

     MindSpring purchased the Assets for $245 million, including $215 million in
cash and $30 million in common stock of MindSpring (376,116 shares, at a per
share price of $79.76). The purchase price was determined based upon an
evaluation of the Business and the result of negotiations conducted by
management under the direction and supervision of MindSpring's Board of
Directors. To finance the acquisition, MindSpring used approximately $135
million of cash on hand and borrowed approximately $80 million on February 17,
1999, under its $100 million secured revolving credit facility with First Union
National Bank and other lenders (the "Credit Facility"). MindSpring's Credit 
Facility is described more fully under the section entitled "Description
of Secured Credit Facility," which is attached as Exhibit 99.1 to this report.

complete and is qualified in its entirety by reference to the Asset Purchase
Agreement, a copy of which is attached as Exhibit 2.1 to this report. A copy of
the press release, dated February 17, 1999, issued by MindSpring regarding the
closing of the NETCOM acquisition is attached as Exhibit 99.2 to this report.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS




To NETCOM On-Line
Communication Services, Inc.:


We have audited the accompanying balance sheets of NETCOM ON-LINE COMMUNICATION
SERVICES, INC. DOMESTIC SUBSCRIBER OPERATIONS (an unincorporated division of
NETCOM On-Line Communication Services, Inc.) as of December 31, 1998 and 1997
and the related statements of operations, accumulated deficit, and cash flows
for the three years in the period ended December 31, 1998. These financial
statements are the responsibility of NETCOM On-Line Communication Services,
Inc.'s management. Our responsibility is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatements. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of NETCOM On-Line Communication
Services, Inc. Domestic Subscriber Operations as of December 31, 1998 and 1997
and the results of its operations and its cash flows for the three years in the
period ended December 31, 1998 in conformity with generally accepted accounting
principles.

                         DOMESTIC SUBSCRIBER OPERATIONS


                          NOTES TO FINANCIAL STATEMENTS

                        DECEMBER 31, 1998, 1997, AND 1996

1.   ORGANIZATION

     NETCOM On-Line Communication Services, Inc. ("NETCOM") was incorporated in
     the state of California in August 1992. In October 1994, NETCOM
     reincorporated in the state of Delaware. In January 1998, in a transaction
     accounted for as a pooling of interests, NETCOM became a wholly owned
     subsidiary of ICG Services, Inc., a Delaware corporation, which is a wholly
     owned subsidiary of ICG Communications, Inc. ("ICG"), and ceased to exist
     as an independent entity. NETCOM provides Internet solutions to subscribers
     in the United States, the United Kingdom and Canada.

     The financial statements and related footnotes contained herein reflect the
     operations of NETCOM's customer base of individual Internet access
     subscribers in the United States (the "Domestic Operations"). These amounts
     exclude the results of NETCOM's operations in Canada and the United Kingdom
     as well as its capital stock. A portion of the Domestic Operations' assets,
     including its subscriber base, intellectual property and facilities, is
     being acquired in a transaction accounted for as a purchase by MindSpring
     Enterprises, Inc. ("MindSpring"). The assets not being acquired will
     continue to be owned by NETCOM (which will change its name in the near
     future) and are expected to be utilized to provide services to MindSpring
     via a Network Services Agreement (Note 8).

     The Domestic Operations has experienced operating losses since inception as
     a result of efforts to build network infrastructure, develop systems and
     expand into new markets. The Domestic Operations expects to continue to
     focus on increasing its subscriber base which could potentially have a
     negative effect on near term financial and operating results. There can be
     no assurance that the Domestic Operations' growth in revenue and subscriber
     base will continue or that it will achieve profitability or positive cash
     flow. The Domestic Operations has been funded to date by NETCOM and will be
     funded by MindSpring subsequent to the acquisition.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES


     PRESENTATION

     The financial statements of the Domestic Operations have been derived from
     the consolidated financial statements of NETCOM and have been prepared to
     present the financial position, results of operations, and cash flows of
     the Domestic Operations on a stand-alone basis. Accordingly, the
     accompanying financial statements for 1998 only include certain
     administrative costs and expenses, which have been allocated to the
     Domestic Operations by NETCOM and its parent, ICG (Note 7). These costs
     have been allocated on a pro rata basis based primarily on employee
     headcount, and represent management's best estimates of what such expenses
     would have been had the Domestic Operations been operated as a separate
     entity.


     ESTIMATES AND ASSUMPTIONS

     The preparation of financial statements in conformity with generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the reported amounts of assets and liabilities and
     disclosure of contingent assets and liabilities at the date of the
     financial statements and the reported amounts of revenues and expenses
     during the reporting period. Actual results could differ from those
     estimates.


     DUE TO PARENT

     NETCOM either advances funds to or borrows funds from the Domestic
     Operations. Funds advanced to the Domestic Operations are used to cover
     fixed asset expansion and working capital requirements. The advances and
     borrowings are netted and are reflected in the "Due to Parent" line item
     included in the accompanying balance sheets.


     REVENUE RECOGNITION

     Monthly subscription service revenue is recognized over the period services
     are provided. Subscription service and equipment revenues, which require
     the use of company-provided installation of equipment at a subscriber's
     location, are recognized when the service is commenced.


     CASH AND CASH EQUIVALENTS

     The Domestic Operations considers all highly liquid investments with an
     original maturity (at the date of purchase) of three months or less and



                                      F-8
<PAGE>   12

     insignificant interest rate risk to be the equivalent of cash for the
     purposes of the balance sheet presentation and statements of cash flows.

     The Domestic Operations has classified all investments as
     available-for-sale and have included them in cash and cash equivalents.
     Available-for-sale securities are carried at fair market value based on
     quoted market prices, with unrealized gains and losses reported in "other
     income." Interest on securities classified as available-for-sale is
     included in "other income." The following is a summary of
     available-for-sale securities at December 31, 1998 and 1997 (in thousands):

     At December 31, 1997, the estimated fair value of the commercial paper and
     money market instruments approximated cost, and the amount of gross
     unrealized gains and losses was not significant.


     ACCOUNTS RECEIVABLE AND DEFERRED REVENUE

     The Domestic Operations generally bills for subscription services,
     including network and dial-up connection services and initial one-time
     setup fees, on the first day of each month for which service is provided.
     Deferred revenue consists primarily of prepaid monthly subscriptions and
     also, to a lesser extent, billings to customers for equipment shipped that
     has not been installed at customer locations.


     INVENTORY

     Inventory consists of purchased goods and is stated at the lower of cost or
     market on a first-in, first-out basis.


     PROPERTY AND EQUIPMENT

     Property and equipment are carried at cost and are depreciated or amortized
     using the straight-line method over the estimated useful life of the
     assets, which is generally three to five years. Leasehold improvements are
     amortized using the straight-line method over the shorter of their
     estimated useful lives or the term of the related lease, whichever is
     shorter.




                                      F-9
<PAGE>   13

     LONG-LIVED ASSETS

     The Domestic Operations periodically reviews the values assigned to
     long-lived assets, such as property and equipment, subscriber acquisition
     costs, and other long-term assets, to determine whether any impairments are
     other than temporary. Management believes that the long-lived assets in the
     accompanying balance sheets are appropriately valued.


     SUBSCRIBER ACQUISITION COSTS

     The Domestic Operations expenses the costs of advertising as incurred,
     except direct response advertising, which are included in subscriber
     acquisition costs. These costs relate directly to subscriber solicitations
     and principally include the printing, production, and shipping of starter
     packages and the costs of obtaining qualified prospects by various targeted
     direct marketing programs. No indirect costs are included in subscriber
     acquisition costs. To date, all subscriber acquisition costs have been
     incurred for the solicitation of specifically identified prospects.
     Subscriber acquisition costs are deferred and amortized over a period
     determined by calculating the ratio of current revenues related to the
     direct response advertising versus the total expected revenues or 12
     months, whichever is shorter. It is possible that these estimates of total
     expected revenues could be reduced in the future. The Domestic Operations'
     management is constantly evaluating the estimates used. As a result, the
     amortization period of the subscriber acquisition costs related directly to
     subscriber solicitations may be reduced.

     Subscriber acquisition costs, which relate directly to potential
     subscribers, are recorded separately from ordinary operating costs.
     Deferred subscriber acquisition costs capitalized during fiscal years 1998
     and 1997 were $16,469 and $5,252, respectively. Amortization and write-offs
     for fiscal years 1998, 1997, and 1996 were $14,377, $7,189, and $11,410,
     respectively.

     Advertising expenses included in selling, general, and administrative
     expenses were $8,268, $3,786, and $5,567 in 1998, 1997, and 1996,
     respectively.


     OTHER INCOME

     In June 1995, the Domestic Operations acquired common stock in the McKinley
     Group, Inc. ("McKinley") in exchange for $1,200 in cash and $300 of common
     stock. In 1996, Excite, Inc. ("Excite") acquired all of the outstanding
     shares of McKinley and the Domestic Operations received shares of Excite in
     exchange for its investment in McKinley. The Domestic Operations recorded a
     loss of $1,200 in 1996 to reflect the estimated value of the shares
     received. During 1997, the Domestic Operations sold the Excite shares for a
     net gain of $1,274.

     SEGMENTAL DISCLOSURES

     The Domestic Operations adopted Statement of Financial Accounting Standards
     ("SFAS") No. 131, "Segmental Disclosures," effective December 31, 1998. The
     standard had no effect, because the Domestic Operations operates in one
     segment.


     CONCENTRATION OF CREDIT RISK

     Financial instruments that potentially subject the Domestic Operations to
     concentrations of credit risk consist principally of cash investments and
     trade receivables. The Domestic Operations' cash investment policies limit
     investments to short-term, low-risk instruments. Concentrations of credit
     risk with respect to trade receivables are limited due to the large number
     of customers comprising the Domestic Operations' customer base.


     SOURCES OF SUPPLIES

     The Domestic Operations relies on local telephone companies and other
     companies to provide data communications capacity. Although management
     feels that alternative telecommunications facilities could be found in a
     timely manner, disruption of these services, for more than a brief period,
     would have an adverse effect on operating results.

     Although the Domestic Operations attempts to maintain multiple vendors for
     each required product, its property and equipment, which are important
     components of its operations, are each currently acquired from only a few
     sources. In addition, some of the Domestic Operations' suppliers have
     limited resources and production capacity. If the suppliers are unable to
     meet the Domestic Operations' needs as it builds out its network
     infrastructure and sells services, then delays and increased costs in the
     expansion of the Domestic Operations' network infrastructure or losses of
     potential customers could result, which would adversely affect operating
     results.


     INCOME TAXES

     The Domestic Operations is not a separate taxable entity. The income tax
     returns of NETCOM include the Domestic Operations. For purposes of these
     financial statements, income taxes allocated to the Domestic Operations
     have been computed and recorded on a separate return basis based on the
     statutory rates in effect (Note 6).

     Income taxes are accounted for under SFAS No. 109, "Accounting for Income
     Taxes." Under this method, deferred tax assets and liabilities are
     determined based on differences between the financial reporting and tax
     bases of assets and 



                                      F-11
<PAGE>   15

     liabilities and are measured using the enacted tax rates and laws that will
     be in effect when the differences are expected to reverse.


     RECLASSIFICATIONS

     Certain prior period amounts have been reclassified to conform to the
     current period presentation.

4.   COMMITMENTS AND CONTINGENCIES


     LEGAL PROCEEDINGS

     NETCOM is subject to legal proceedings and claims that have arisen in the
     ordinary course of its business related to the Domestic Operations. In the
     opinion of management, settlement of these actions when ultimately
     concluded will not have a material adverse effect on trends in results of
     operations or the financial condition of NETCOM or the Domestic Operations.
     This conclusion is based on current facts and circumstances, however, and
     it is possible that a change in the facts and circumstances relating to
     such legal proceedings and claims could result in a development that would
     have a material adverse effect on the results of operations or financial
     condition of the Domestic Operations.

     NETCOM has allocated to the Domestic Operations leases on certain equipment
     under agreements that are classified as capital leases. These leases have
     original terms of three years or less and contain bargain purchase options
     at the end of the original lease terms. The Domestic Operations also has
     operating leases which relate to the lease of office and equipment space.
     Rental expense attributable to these operating leases was approximately
     $5,569, $5,291, and $4,237 for the years ended December 31, 1998, 1997, and
     1996, respectively. At December 31, 1998, the Domestic Operations' capital
     lease obligations and minimum rental commitments under noncancelable
     operating leases with initial or remaining terms of more than one year were

5.   EMPLOYEE BENEFIT PLANS

     The option plans and 401(k) plan of NETCOM, as assumed by ICG, include the
     Domestic Operations. For purposes of these financial statements, all option
     information related to the Domestic Operations has been computed and
     recorded on a separate entity basis.

     EMPLOYEE SAVINGS PLAN

     NETCOM has a savings plan (the "Savings Plan") that qualifies as a deferred
     salary arrangement under Section 401(k) of the Internal Revenue Code. Under
     the Savings Plan, participating employees may defer a portion of their
     pretax earnings up to the Internal Revenue Service annual contribution
     limit. NETCOM matches 50% of each employee's contribution up to a maximum
     of 6% of the employee's eligible earnings. NETCOM matches vest over four
     years. NETCOM has not made any material matching contributions to the
     Savings Plan for the related periods.

     1993 STOCK OPTION PLAN

     In 1993, NETCOM approved and adopted its 1993 Non-qualified Stock Option
     Plan (the "Plan"). The Plan is administered by the stock option committee
     of the Board of Directors. The Plan provides for the granting of options to
     purchase common stock to eligible employees, directors, and consultants of
     NETCOM. A total of 3,153,571 shares of common stock may be issued pursuant
     to options granted under the Plan. The options generally vest over three-
     to five-year periods and are exercisable for up to ten years following the
     date of grant.

     ICG PLAN

     NETCOM's 1993 Stock Option Plan was assumed by ICG at the time of the
     merger (Note 1), and approved by ICG's Board of Directors as an incentive
     and non-qualified stock option plan which provides for the granting of
     options to certain directors, officers and employees to purchase 2,720,901
     shares of ICG Common Stock. A total of 4,380,099 options were granted under
     this plan at exercise prices ranging from $0.65 to $92.14, none of which
     were less than 100% of the estimated fair market value of the shares
     underlying the options on the date of grant, and accordingly, no
     compensation expense was recorded for these options under APB 25. The
     options granted under this plan are subject to various vesting
     requirements, generally three years and five years, and expire within ten
     years from the date of grant.

     In order to continue to provide non-cash inventive and retain key
     employees, all employee stock options outstanding on September 18, 1998
     with exercise prices at or in excess of $22.00 were canceled by the Stock
     Option Committee of ICG's Board of Directors and regranted with an exercise
     price of $16.88. A total of 757,058 of NETCOM's options, with original
     exercise prices ranging from $22.02 to $35.75 where canceled and regranted.

     During the 1994 fiscal year, NETCOM's Board of Directors approved and
     adopted an Employee Stock Purchase Plan which was dissolved upon the merger
     with ICG. Shares purchased under this plan were converted into an estimated
     119,000 shares of ICG Common Stock.


     STATEMENT OF FINANCIAL ACCOUNTING STANDARDS NO. 123

     The Domestic Operations has elected to account for its stock-based
     compensation plans under Accounting Principles Board Opinion No. 25 ("APB
     25"); however, the Domestic Operations has computed for pro forma
     disclosure purposes the value of all options granted during the years ended
     December 31, 1998, 1997, and 1996 using the Black-Scholes option pricing
     model as prescribed by SFAS No. 123 using the following weighted average
     assumptions:

</TABLE>

     The total value of options granted during the years ended December 31,
     1998, 1997, and 1996 was computed as approximately $21,527, $39,132, and
     $14,199, respectively, which would be amortized on a pro forma basis over

     During 1996 and early in 1997, certain outstanding options were exchanged
     at the election of the option holder. In September 1996, 67,408 shares were
     exchanged and repriced for 39,995 shares, and in January 1997, 457,846
     shares were exchanged and repriced for 272,084 shares on the effective date
     of the trade-in. Eligible options were issued at a lower price than the
     traded-in options and at a price higher than the market value. The trade-in
     ratio was set such that the number of old options times their option price
     approximates the new number of options times their exercise price. This
     program was offered to all NETCOM employees, excluding members of the Board
     of Directors and officers. However, option holders participating in the
     first exchange were not eligible for the second program.

6.   INCOME TAXES

     Deferred income taxes reflect the net tax effect of temporary differences
     between the carrying amount of assets and liabilities for financial
     reporting purposes and the amounts used for income tax purposes. As
     discussed in Note

     2, the Domestic Operations is not a separate legal entity, but is included
     in the consolidated return of NETCOM. Therefore, no tax-sharing arrangement
     exists between NETCOM and the Domestic Operations. Significant components
     of the Domestic Operations' allocated deferred tax assets and liabilities
     for federal and state income taxes as of December 31, 1998 and 1997 are as

</TABLE>

     Realization of deferred tax assets is dependent on future earnings, the
     timing and amount of which are uncertain. Accordingly, a valuation
     allowance, in an amount equal to the net deferred tax assets as of December
     31, 1998 and 1997, has been established to reflect these uncertainties. The
     change in the valuation allowance was a net increase of $18,078 and $8,150
     in 1998 and 1997, respectively.

     As of December 31, 1998 and 1997, the Domestic Operations portion of
     NETCOM's federal and state net operating loss carryforwards was
     approximately $174,678 and $125,763, respectively, which will expire in the
     years 1999 through 2011. In addition, NETCOM's ability to recognize the
     Domestic Operations' portion of the benefit from the net operating loss
     carryforwards will be limited under Section 382 of the Internal Revenue
     Code, because the ownership of NETCOM has changed more than 50%, as
     defined.

     A reconciliation of the income tax provision computed at statutory tax
     rates to the income tax provision for the years ended December 31, 1998,
     1997, and 1996 is as follows:

     In addition, the Domestic Operations has realized the benefit of
     non-qualified stock compensation expense for tax purposes in excess of
     stock compensation expense for book purposes of $8.2 million, $0.3 million,
     and $7.6 million for the years ended December 31, 1998, 1997, and 1996,
     respectively. These amounts have been credited directly against due to
     parent, net of a full valuation allowance.


7.   RELATED-PARTY TRANSACTIONS

     Prior to the ICG merger, the Domestic Operations' only related-party
     transactions were certain cash advances to the international operations of
     NETCOM. The amount of these advances at December 31, 1998 and 1997 were
     $38,125 and $32,352 and is included in due to parent.

     Subsequent to the merger, ICG assumed the treasury function, so that all of
     the Domestic Operations' cash at December 31, 1998 is netted in due to
     parent. Additionally, ICG provided services in the area of risk management
     and benefits. Estimated costs attributable to these support functions are
     included in selling, general, and administrative expenses. These costs are
     allocated to the Domestic Operations based on various factors that NETCOM
     management believes represent relative cost streams and fair market value.
     The costs allocated to the Domestic Operations were approximately $957 for
     the year ended December 31, 1998.

     Following the merger, the Domestic Operations began using certain
     telecommunications services of ICG. ICG charged NETCOM $2,170 for such
     services for the year ended December 31, 1998 and are included in cost of
     revenue. Similarly, the Domestic Operations provided certain technical
     services to ICG. ICG charged NETCOM $1,678 for such services for the year
     ended December 31, 1998 and are included in revenues. The rates charged for
     such services approximate market value, in the opinion of NETCOM's
     management.


8.   SUBSEQUENT EVENTS (UNAUDITED)

     On January 5, 1999, MindSpring Enterprises, Inc. ("MindSpring") and NETCOM
     entered into an Asset Purchase Agreement, pursuant to which MindSpring
     agreed to acquire for a purchase price of $215 million in cash and $30
     million in MindSpring stock certain of the tangible and intangible assets
     and rights in connection with the consumer dial-up Internet access business
     operated by NETCOM, as well as the Domestic Operations' domestic subscriber
     base. As part of this transaction, MindSpring and NETCOM (which will change
     its name in the near future) entered into a Network Services Agreement for
     one year with an option for a second year on potentially different terms to
     be 



                                      F-18

     negotiated and accepted by both parties. Under the Network Services
     Agreement, MindSpring subscribers will be able to access the Internet
     through ICG's network points-of-presence. This transaction was completed on
     February 17, 1999, and will be accounted for as a purchase.

                       UNAUDITED PRO FORMA FINANCIAL DATA

     The following pro forma balance sheet reflects the acquisition by
MindSpring of certain assets of NETCOM On-Line Communication Services, Inc.
Domestic Subscriber Operations (the "NETCOM Domestic Operations") as if it had
occurred on December 31, 1998. The following pro forma statement of operations
for the year ended December 31, 1998 reflects the acquisition by MindSpring of
certain assets of the NETCOM Domestic Operations and of Spry, Inc. ("Spry") as
if they had occurred on January 1, 1998. The pro forma financial information
does not purport to represent what MindSpring's consolidated results of
operations would have been if the acquisitions had in fact occurred on these
dates, nor does it purport to indicate MindSpring's future consolidated
financial position or future consolidated results of operations. The pro forma
adjustments are based on currently available information and certain assumptions
that MindSpring's management believes are reasonable.

     (a)  Adjustments have not been made to cost of revenue or to selling,
          general and administrative costs. However, cost of revenue and
          selling, general and administrative costs incurred by Spry and the
          NETCOM Domestic Operations may not be indicative of the cost of
          revenue and selling, general and administrative costs that would have
          been incurred by MindSpring in relation to the same assets. In
          connection with MindSpring's acquisition of the NETCOM Domestic
          Operations, MindSpring and NETCOM (which will change its name) have
          entered into a network services agreement, for one year with an option
          for a second year on potentially different terms to be negotiated and
          agreed to by the parties. MindSpring expects to use the network
          services purchased under this agreement initially to provide service
          to the subscribers acquired from NETCOM. MindSpring expects that the
          costs it incurs for such network services will be different than the
          corresponding historical costs reported by NETCOM. In this regard,
          cost of revenue and selling, general and administrative costs incurred
          by MindSpring in future periods may be materially different from the
          amounts reflected in the pro forma financial statements.

     (b)  Represents additional amortization based on preliminary purchase price
          allocation (as noted in footnote (a) to the pro forma balance sheet)
          for the NETCOM Domestic Operations and a full year of amortization of
          the $32.5 million purchase price paid by MindSpring for the
          acquisition of certain Spry assets using a three-year amortization
          period.

     (c)  Represents the adjustment to conform the accounting policy of the
          acquired companies to those of MindSpring with respect to depreciable
          lives as well as adjust the historical depreciation for the assets not
          being acquired.



                                      F-22

     (d)  Reflects additional interest expense on anticipated borrowings under a
          secured revolving credit facility (as noted in footnote (a) to the pro
          forma balance sheet) at an assumed interest rate of 6.69%, as if such
          borrowings were outstanding since January 1, 1998.

     (e)  Reflects (i) 3 million shares of MindSpring common stock issued in a
          public offering completed on May 29, 1998; (ii) 2.3 million shares of
          MindSpring common stock issued in a public offering completed on
          December 14, 1998; and (iii) approximately 376,000 shares of
          MindSpring common stock issued to NETCOM On-Line Communication
          Services, Inc. as part of the purchase price for the NETCOM Domestic
          Operations assets (representing approximately $30 million, at $79.76
          per share) as if such shares were outstanding since January 1, 1998.
          Also, excludes the effect of stock options for purposes of the diluted
          earnings per share calculation, since the effect for pro forma
          purposes is antidilutive.

       SECTION 2.1. Basic Transaction.

       (a)    Subject to the terms and conditions set forth in this Agreement,
Buyer agrees to purchase and assume from Seller, and Seller agrees to sell and
transfer to Buyer, or to such Affiliate or Affiliates of Buyer as Buyer may

comprise, and Seller will assign and transfer to Buyer at the Closing, all of
the real, personal and mixed assets and property, both tangible and intangible,
which are being used or held for use by Seller in the conduct of the Business,
as of the date of this Agreement and as of and at the Closing consistent with

                                      -7-
<PAGE>   13

1.1(i), 1.1(III), 3.9(a), 3.10 and 3.16, may not describe the Assets with the

property comprising the Assets, including tangible and intangible property, the
names of all Subscribers as of a date no earlier than five days prior to the
Closing, and the Intellectual Property, and will deliver such inventory to Buyer
as promptly as practicable but in any event no earlier than ten days or later
than five days prior to the Closing Date.

              (ii) The Parties acknowledge and agree to the following in respect
of Intellectual Property comprised of computer software:

                     (A) Computer software used or held for use by Seller as of
the date of this Agreement consists of the following five categories:

                            (1) Software licensed from third parties that is not
assignable to Buyer by its terms if the licensor of such software withholds its
consent to such assignment (where the requirement of such consent is
applicable); provided that Seller will use its commercially reasonable best
efforts to secure such consent;

                            (2) Software licensed from third parties that is
used exclusively in connection with the Business and that is assignable either
by its terms or pursuant to the consent of the other parties thereto where such
consent is obtained;

                            (3) Internally-developed software that is used
exclusively in connection with the Business;

                            (4) Software licensed from third parties and
internally-developed software that is used exclusively in connection with the
Network; and

                            (5) Software licensed from third parties and
internally-developed software that is used both in connection with the Business
and the Network.

Based on the above clauses (1) through (5), the Parties further agree as
follows: (a) ownership of the software described in the preceding clauses (1)
(subject to the provisions of Section 2.1(d)) and (4) will be retained by Seller
and constitute part of the Retained Assets and will not be considered to be
Assets under this Agreement; (b) ownership of the software described in the
preceding clause (2) will be assigned to Buyer; (c) ownership of the software
described in the preceding clause (3) will be assigned and transferred to Buyer;
(d) software described in the preceding clause (5) will be licensed to Buyer
under a worldwide, perpetual, royalty-free licensing arrangement (including both
source and object code) to be mutually satisfactory to Seller and Buyer and
under which arrangement both Seller and Buyer will have unfettered use of such
software and the right to modify and develop such software consistent with the
operation of each of their respective businesses after the Closing; and (e) if
any software described above the ownership of which is transferred to Buyer
under this paragraph is used in connection with the business conducted by NETCOM
Canada, Inc. or NETCOM Internet, Ltd., such use to be determined in Seller's
reasonable discretion, Buyer will enter into with Seller as of the Closing a


                                      -8-
<PAGE>   14

perpetual, royalty-free license arrangement (including both source and object
code), to be mutually satisfactory to Buyer and Seller, providing for the
unfettered use of such software in Canada and/or the United Kingdom, as the case
may be, and the right to modify and develop such software consistent with the
operation of the business by those two Affiliates of Seller. In furtherance of
the agreements set forth in this Section 2.1(c)(ii), the Parties will cooperate
with each other, and enter into appropriate agreements and licensing
arrangements to be effective as of the Closing, to ensure the continued use of
such software to the maximum extent possible by Buyer and Seller (and to the
extent applicable, by NETCOM Canada, Inc. or NETCOM Internet, Ltd.) after the
Closing in connection with their operation of the Business and the Network (and
the business conducted by NETCOM Canada, Inc. or NETCOM Internet, Ltd., as
applicable), respectively.

       (d)    Notwithstanding anything else in this Agreement to the contrary,
this Agreement shall not constitute an agreement to assign or transfer any Asset
or part thereof or any rights or benefit arising thereunder or resulting
therefrom if an attempted assignment or transfer thereof, without the consent of
a third party thereto, would constitute a breach thereof, or make Buyer or
Seller liable for damages or other penalties. If such consent is not obtained
prior to Closing, or if an attempted assignment thereof would be ineffective or
would affect the rights of Buyer or Seller so that Buyer would not in fact
receive substantially all such rights, Seller (i) at Seller's cost and expense
shall continue to use its commercially reasonable efforts to obtain such consent
and (ii) if any such consent is unobtainable, shall cooperate with Buyer in a
mutually agreed-upon arrangement under which at Seller's cost and expense Buyer
would obtain the benefits and assume the obligations thereunder, or under which
Seller would enforce for the benefit of Buyer, at Buyer's cost and expense, with
Buyer assuming Seller's obligations, any and all rights of Seller against a
third party thereto. To the extent the benefits therefrom have been provided to
Buyer by alternative arrangements as provided above or a consent is obtained,
the contract, agreement or other asset shall be deemed to be an Asset
transferred to Buyer.

       SECTION 2.2. Purchase Price. At the Closing, and in addition to the
assumption of the Assumed Liabilities as set forth in Section 2.4, Buyer agrees
to pay to Seller, and Seller agrees to accept from Buyer, an aggregate purchase
price (the "Purchase Price") equal to Two Hundred Forty-Five Million Dollars
($245,000,000), payable as described in Section 2.3. The Purchase Price will be
allocated among the Assets in accordance with Section 5.8.

       SECTION 2.3. Payment of Purchase Price. The Purchase Price shall be
payable to Seller at the Closing as follows:

       (a)    Buyer will pay to Seller the amount of Two Hundred Fifteen Million
Dollars ($215,000,000) in cash in immediately available funds by wire transfer
to an account or accounts designated in writing by Seller; and

       (b)    Buyer will deliver to Seller certificates representing that number
of shares (the "Shares") of MindSpring Stock obtained by dividing (i) Thirty
Million Dollars ($30,000,000) by (ii) the average closing price for the

days ending the last trading day immediately before the Closing. The Shares 



                                      -9-
<PAGE>   15

will be delivered to Buyer at the Closing free and clear of all Liabilities,
Taxes and other Encumbrances, other than those allowed to arise solely by
Seller.

       (c)    Within ten days following the Closing Date, Buyer and Seller will
make a calculation to determine whether there shall be a Purchase Price
adjustment. For the purposes of this calculation, as of the Closing Date each
dial-up Subscriber will be valued at $490.1838, each Web-hosting Subscriber will
be valued at $1,225.4595 and each dedicated access Subscriber will be valued at
$12,254.5950. If Buyer and Seller calculate that the aggregate value of all the
Subscribers who are current customers (as defined in Section 3.20) as of the
Closing Date is less than Two Hundred Forty Million One Hundred Thousand Dollars
($240,100,000), a Purchase Price adjustment will be payable in cash from the
Seller to the Buyer in an amount equal to the difference between such aggregate
value and Two Hundred Forty Million One Hundred Thousand Dollars ($240,100,000),
such payment to be made by Seller within 15 days after the Closing Date.

       SECTION 2.4. Assumption of Liabilities.

       (a)    At the Closing, Buyer, or the Affiliate of Buyer that purchases
the Assets pursuant to Section 2.1(a), as the case may be, will assume the
Assumed Liabilities. Except for the Assumed Liabilities, Buyer (or such
Affiliate) will not assume or have any responsibility for any liabilities or
other obligations of any kind or description of Seller, whether connected with
the Business, the Assets or otherwise.

       (b)    (i) Except as provided in Section 2.4(b)(ii), as of the Closing,
Buyer will offer to employ all of the employees of the Seller (including for
this purpose all employees of Seller hired in the Ordinary Course of Business in
connection with the Business after the date of this Agreement and before the
Closing) other than the employees that are listed on SCHEDULE 2.4(b) as of the
Closing Date; provided that Buyer will not be prevented from terminating the
employment of any such employee after the Closing in accordance with Buyer's
practices and procedures. A preliminary list of the employees to be employed by
Buyer under this Section 2.4(b)(i) as of the Closing is set forth on SCHEDULE
3.18, which list will be finalized within ten days following the date of this
Agreement and contain a listing of employees reasonably necessary for the
operation of the Business. SCHEDULE 2.4(b) sets forth a preliminary list of
employees to be employed by Seller after the Closing, which list will be
finalized within ten days following the date of this Agreement. Buyer will not
assume, and will have no Liability with respect to, any Plan maintained or
contributed to by Seller, and will not assume, and will have no liability for,
any Liability arising out of or accruing during the period prior to the Closing,
except as expressly set forth in the next sentence or Section 2.4(b)(iii). After
the Closing, Buyer will comply with the requirements, if any, under the WARN Act
with respect to the employees who accept employment offers from Buyer under this
Section 2.4(b)(i) and are subsequently terminated by Buyer. Buyer will assume
all costs of employee compensation and other Liabilities relating to such
employees attributable to the period after the Closing. Seller will remain
responsible for all Legal Requirements relating to group health plan
continuation coverage to which any employee or former employee (or dependent of
either) of Seller is entitled because of a qualifying event (as defined in
Section 4980(f)(3) of the Code) occurring through 


                                      -10-
<PAGE>   16

the Closing Date, and any benefit or excise tax liability or penalty or other
costs arising from any failure by Seller to provide such group health plan
continuation coverage.

       (ii)   By written notification to Seller at least ten days prior to the
Closing, Buyer may identify those executive officers of Seller who Buyer will
not offer to employ as of the Closing, and Buyer will have no responsibility
for, and bear no Liability for, those identified executive officers under
Section 2.4(b)(i). Buyer agrees that for a period of six months following the
Closing, neither Buyer nor any of its Affiliates will employ any of such
identified executive officers, whether as an employee, consultant, independent
contractor, advisor or in any other capacity. The Parties agree that the
restriction set forth in the preceding sentence is a material element of this
Agreement and will be specifically enforceable by Seller against Buyer, and upon
a breach by Buyer of such restriction, Buyer agrees that Seller could not be
adequately compensated at law.

       (iii)  Buyer will assume the obligation to pay bonuses and vacation pay
accrued on the books and records of Seller as of the Closing, in an amount not
to exceed One Million Seven Hundred Thousand Dollars ($1,700,000), with respect
to the employees who Buyer is required to offer to employ as of the Closing in
accordance with Section 2.4(b)(i). Within ten days after the Closing, Seller
will pay to Buyer in cash Five Hundred Thousand Dollars ($500,000) in respect of
the obligation assumed by Buyer for vacation pay described in the immediately
preceding sentence. In the event that Buyer actually pays any bonuses to any
such employee and such bonuses relate to any period preceding the Closing Date,
Seller will reimburse Buyer for all amounts actually paid with respect to such
bonuses to the extent that such amounts relate to any period preceding the
Closing Date; provided that the aggregate amount to be reimbursed by Seller to
Buyer under this sentence will not exceed One Million Two Hundred Thousand
Dollars ($1,200,000). All bonus reimbursements required by Seller under this
Section 2.4(b)(iii) will be paid to Buyer within ten days of the receipt by
Seller from Buyer of evidence reasonably satisfactory to Seller of the payment
by Buyer of reimbursable bonuses.

       SECTION 2.5. Closing; Closing Date. The closing of the transactions

a valid and binding obligation of Seller in accordance with its terms, and, to
Seller's knowledge, is legally enforceable in accordance with its terms. Seller
is not in default under any Seller Contract and, to Seller's knowledge, there
does not exist any event that (whether with or without notice, lapse of time, or
the happening or occurrence of any other event) would result in such a default.
To Seller's knowledge, there exists no default by any other party to any Seller
Contract. Within the last year, Seller has not received any written notice from

as supplemented, will contain all such notices, consents, waivers or approvals
except for any such notices, waivers, consents or approvals the failure of which

knowledge of Seller is there any basis for any such action.

<PAGE>   23

       (b)    The Assets and Seller's ownership, lease and use of the Assets are
not in violation of any applicable material Legal Requirement. Seller has not
received notice from any Governmental Authority or other Person of any violation
or alleged violation of any material Legal Requirement relating to the Business
or the Assets, and no action, suit, proceeding, hearing, investigation, charge,
complaint, claim, demand or notice has been filed or commenced or is pending or,
to the knowledge of Seller, threatened against Seller with respect to any such

material authorizations, Permits, licenses and Orders required or necessary to

302 of ERISA) exists with respect to any Plan.

       (c)    Seller has not ever been required to contribute to any
multiemployer plan (as defined in Section 3(37) of ERISA).


       SECTION 3.14. Labor and Employment. Except as described on SCHEDULE 3.14,
there are no material labor or employment controversies pending or, to the
knowledge of Seller, threatened against Seller which could reasonably be
expected to have a Material Adverse Effect. Except as disclosed on SCHEDULE
3.14, there are no collective bargaining agreements, employment agreements
between Seller and any of its Employees, or professional service agreements not
terminable at will relating to the Business or any of the Assets. Except as set
forth in Section 2.4(b)(i), the sale of the Assets and the Business to Buyer
pursuant to the terms of this Agreement will not cause Buyer to incur or suffer
any liability relating to, or obligation to pay, severance, termination or other
similar payments to any current or former employee or independent contractor of

       SECTION 3.15. Environmental Matters. Seller is conducting and at all
times has conducted the Business, and has occupied, used and operated the

under any Environmental Obligations or to any Material Adverse Effect.

       SECTION 3.16. Intellectual Property.

       (a)    Within ten days of the date of this Agreement, Seller will provide
to Buyer a partial list of all Intellectual Property, which list will be
supplemented by the inventory pursuant to Section 2.1(c)(i) and which list, as
supplemented, will constitute a true, correct and complete list of all
Intellectual Property. Such list will identify Seller as either the owner, joint
owner or licensee of each item of Intellectual Property and in the cases where

Persons other than Seller with respect to the Intellectual Property, other than
such rights that are described on SCHEDULE 3.16. All federal and foreign

Intellectual Property required to be identified herein:

              (i)    such Intellectual Property is not subject to any
outstanding injunction, judgment, order, decree, ruling or charge;

              (ii)   no action, suit, proceeding, hearing, investigation,
charge, complaint, claim or demand is pending or, to the knowledge of Seller, is

Business.

       (c)    Seller has not received notice, orally or in writing, that any

the authorization of every other claimant thereto and the execution, delivery

any notice, charge, claim or assertion of, nor brought any action for, and

account of any brokerage, finder's or similar fee payable with respect to
services rendered to Seller or any of Seller's directors, officers, employees or
agents in connection with the transactions contemplated by this Agreement.
Seller will pay and discharge any amounts owing to Salomon Smith Barney as a
result of the transactions contemplated by this Agreement.

       SECTION 3.18. Employees. Seller has no written employment contract with
any person with respect to the Business except any employment contracts as are
set forth on SCHEDULE 3.14. SCHEDULE 3.18 sets forth a preliminary list of all
current employees of Seller employed with respect to the Business (collectively,
the "Employees"), showing each such Person's name, position, initial employment
date, and annual remuneration (without exclusions for deduction pursuant to Code
Sections 125 or 401(k)), plus actual bonus or incentive compensation paid in
calendar year 1998, if any, which list will be finalized within ten days
following the date of this Agreement. Except as set forth on SCHEDULE 3.18 or
otherwise entered into in the Ordinary Course of Business, other than general
understandings which may exist for employment at will, no oral understandings
currently exist between any executive officer or other representative of Seller
authorized to enter into such understandings on behalf of Seller and any

dial-up, Web-hosting and dedicated access, respectively, Subscribers that are
current customers (that is, Subscribers who paid for service the last time their

non-credit card Subscribers who paid for service within 31 days of 



                                      -20-
<PAGE>   26

receipt of their most recent invoice), and the average revenue per Subscriber
with respect thereto, are not less than as shown on SCHEDULE 3.20. As of the
Closing, Seller will certify whether or not the aggregate value of the
Subscribers who are current customers (as provided in the prior sentence, and as
determined as of the Closing) is at least One Hundred Ninety Six Million Dollars
($196,000,000), using for purposes of calculation the values for such
Subscribers set forth in Section 2.3(c).

       SECTION 3.21. Securities Matters.

       (a)    Seller is experienced in evaluating and investing in
high-technology companies such as Buyer. Seller has substantial experience in
investing in and evaluating private placement transactions of securities in
companies similar to Buyer and is capable of evaluating the risks and merits of
its investment in Buyer and has the capacity to protect its own interests.

       (b)    Seller is acquiring the Shares for investment for its own account
and not with a view to, or for resale in connection with, any distribution
thereof, except in compliance with applicable securities laws, and Seller has no
present intention of selling or distributing the Shares except in compliance
with applicable securities laws. Seller understands that as of the date of this
Agreement the Shares have not been registered under the Securities Act.

       (c)    Seller acknowledges that, because the Shares have not been
registered under the Securities Act, the Shares that Seller receives at the
Closing must be held indefinitely unless subsequently registered under the
Securities Act or an exemption from such registration is available. Seller is
aware of the provisions of Rule 144 promulgated under the Securities Act which
permits limited resale of shares purchased in a private placement subject to the
satisfaction of certain conditions, including, among other things, the resale
occurring not less than one year after a party has purchased and paid for the
security to be sold.

       (d)    Without in any way limiting the effect of the representations and
warranties of Buyer set forth in this Agreement, Seller has had an opportunity
to discuss in detail Buyer's business, management and financial affairs with
Buyer's officers and management employees and has reviewed all documents and
records of Buyer which Buyer has provided in response to Seller's request.

       (e)    Seller is an "accredited investor" as that term is defined in Rule
501(a) under the Securities Act. Seller has not been organized for the specific
purpose of acquiring Shares.

       (f)    Seller has its principal office in the State of California.

       SECTION 3.22 Year 2000 Compliance. To the knowledge of Seller, without
any investigation or due diligence on its part or on the part of any of Seller's
employees or any other Person, the Seller Software accurately processes
date/time data (including calculating, comparing, and sequencing) from, into,
and between the twentieth and twenty-first centuries, and the years 1999 and
2000 and leap year calculations when either (A) used as a standalone
application, or (B) integrated into or otherwise used in conjunction with the
third party hardware, 


                                      -21-
<PAGE>   27

software, firmware and data ("Third Party Products") with
which such Seller Software was designed or intended to operate at the time such
Seller Software was (i) developed or (ii) first provided to Seller's customers
or tested by Seller for such customers, whichever is later. Notwithstanding the
foregoing, the Seller shall not be considered to be in breach of the
representation and warranty in the immediately preceding sentence if the failure
of such Seller Software to comply with such representation and warranty is
attributable solely to (x) a failure by any Third Party Product to accurately
process date/time data (including but not limited to, calculating, comparing,
and sequencing) from, into, and between the twentieth and twenty-first
centuries, and the years 1999 and 2000 and leap year calculations; or (y) any
modification of the Seller Software by any party other than Seller (unless such
modification was made at the direction of Seller). As Buyer's sole and exclusive
remedy for breach of the representation and warranty in this Section 3.22,
Seller will (i) exercise commercially reasonable best efforts to correct any
material breach of the warranty reported to Seller on or before June 30, 2000
and (ii) provide any resulting fix to Buyer without charge.

       SECTION 5.1. General. Each of the Parties will use its commercially
reasonable efforts to take all actions necessary, proper or advisable, in order
to consummate and make effective the transactions contemplated by this Agreement
(including the satisfaction, but not the waiver, of the closing conditions set

       SECTION 5.2. Operation and Preservation of Business. Seller will through

relations therewith; and (b) maintain the Assets in the same working order and
condition as the Assets are in on the date of this Agreement, consistent with
how the Assets historically have been maintained in the Ordinary Course of
Business, reasonable wear and tear excepted. Except as contemplated by this
Agreement or as reasonably required to carry out its obligations hereunder,
Seller will, through the Closing Date, conduct the Business in the Ordinary
Course of Business and, in addition, will not (except to the extent that Buyer
has consented in writing thereto or that such action or inaction would not
reasonably be expected to materially affect or be binding upon any part of the
Business or the Assets): (i) grant any increase in the compensation payable or
to become payable by Seller to officers or employees of the Business other than
in the Ordinary Course of Business, or enter into any bonus, insurance, pension,
profit sharing, incentive, deferred compensation, severance pay, retirement,
hospitalization, employee benefit or other similar plan, payment or arrangement
for or with any of such officers or employees other than in the Ordinary Course
of Business; (ii) enter into any agreement in connection with the Business that

any act (or permit such action or omission) which reasonably could be expected
to cause a material breach of any Seller Contract; or (viii) take any action or
fail to take any action that would reasonably be expected to cause any of the
representations, warranties or covenants of Seller contained herein to be untrue
or incorrect in any material respect or incapable of being performed or
satisfied on the Closing Date. Prior to the Closing Date, Seller will maintain
in full force and effect all of its existing casualty, liability, and other

       SECTION 5.3. Full Access. Seller will permit Buyer and its agents to have
full access at all reasonable times, and in a manner so as not to interfere with
the normal business operations of Seller, to all Premises, properties,
personnel, accounting books and records, contracts and documents of or

provisions set forth in this Agreement.

       SECTION 5.4. Notice of Developments.

       (a)    Seller will give prompt written notice to Buyer of any development

SCHEDULES of Seller, and will provide Buyer with all information (including,
without limitation, copies of all documents relating thereto) reasonably
requested by Buyer concerning any claims instituted, threatened or asserted
after the date of this Agreement against or affecting the Business or Assets at
law or in equity before or by any Governmental Authority.

       (b)    Promptly after Seller has knowledge thereof, Seller will, through
the Closing Date, notify Buyer in writing of the occurrence of any event, or the
failure of any event to occur, prior to the Closing that results in a breach of
any of the covenants, representations or warranties made by or on behalf of
Seller in this Agreement, but, in the event the Closing occurs and subject to
the second sentence of Section 8.5(a), such notification will not excuse
breaches of representations, warranties, covenants or agreements disclosed in
such notification.

       (c)    Promptly after Buyer has knowledge thereof, Buyer will, through
the Closing Date, notify Seller in writing of the occurrence of any event, or
the failure of any event to occur, prior to the Closing that results in a breach
of any of the covenants, representations or warranties made by or on behalf of
Buyer in this Agreement or any other document or agreement furnished by Buyer in

(including disclosure requirements under applicable securities laws), neither
Buyer, nor Seller will make any disclosure of the information described in this
Section 5.6. Nothing contained in this Agreement shall be construed to prohibit
any Party from disclosing the information described in this Section 5.6 or any
Confidential Information in 


                                      -25-

connection with the institution or defense of any claim pursuant to this
Agreement or other claims which may be the subject of judicial proceedings.

       SECTION 5.7. Consents and Approvals.

       (a)    The Parties, at each of their own expense except as otherwise
provided in this Agreement, shall take all commercially reasonable measures
reasonably necessary or advisable to secure such consents, authorizations and
approvals of Governmental Authorities and of other Persons or entities with
respect to the transactions contemplated by this Agreement, and to the
performance of all other obligations of such Parties under this Agreement, as
may be required by any applicable statute or regulation of the United States or
any country, state or other jurisdiction or by any agreement of any kind
whatsoever to which Buyer or Seller is a party or by which Buyer or Seller is
bound.

       (b)    Buyer and Seller will (i) cooperate in the filing of all forms,
notifications, reports and information, if any, required or reasonably deemed
advisable pursuant to applicable statutes, rules, regulations or orders of any
Governmental Authority in connection with the transactions contemplated by this

promptly as practicable, and in any event no later than 15 days following the
execution of this Agreement, Seller and Buyer will complete any filing that may
be required pursuant to Hart-Scott-Rodino, or shall mutually agree that no such
filing is required. Seller and Buyer will diligently take (or fully cooperate in
the taking of) all actions, and provide any additional information, required or
reasonably requested in order to comply with the requirements of
Hart-Scott-Rodino. Buyer and Seller will each pay one-half of the
Hart-Scott-Rodino filing fee.

       SECTION 5.8. Values of Assets. As soon as practicable after the Closing
(but not later than 75 days after the Closing Date, Buyer will prepare and
submit to Seller for its approval, which approval will not be unreasonably
withheld, a schedule allocating the Purchase Price among the Assets. For
purposes of this allocation, the Purchase Price will be deemed to include the
amount of the Assumed Liabilities. Seller will be required to approve such
allocation so long as it is reasonable. Seller will be deemed to have approved
such allocation unless it gives written notice of objection to Buyer within ten
days after receipt of the schedule setting forth such allocation. If such notice
of objection is given, within five days after such notice is given, the dispute
will be submitted to Arthur Andersen LLP, whose determination will be
conclusive. The fees and expenses payable to such firm will be borne equally by
Seller and Buyer. When the allocation of the Purchase Price is finally
determined, the Parties will report the allocation of the Purchase Price
according to that determination for all applicable income, sales, use and
transaction Tax purposes, and Seller and Buyer will file all required Tax forms
with the applicable Taxing authorities consistent with such determination.

       SECTION 5.9. Name. As of the Closing, Seller will change its corporate
name to a name dissimilar to its current name, which name will not include the
word "NETCOM," and thereafter will not use the word "NETCOM" in its corporate

the tradename "NETCOM" nor use such name in any service mark, and any pending
applications for the use of such name will be abandoned.

       SECTION 5.10. Resale Prospectus. Provided that Seller has provided or

required by Buyer for inclusion therein, Buyer will prepare and file with the
SEC as promptly as practicable after the date of this Agreement a resale
registration statement on Form S-3 or other eligible Form (the "Resale

provides for the sale by Seller of the Shares after the Closing. Buyer will
provide to Seller for its review a draft copy of the Resale Prospectus prior to
its filing with the SEC. Buyer will use its commercially reasonable best efforts
to cause the Resale Prospectus to become effective with the SEC as of the
Closing or, if such effectiveness does not occur or is not permitted under
applicable federal securities laws, as soon as possible after the Closing.

                                   ARTICLE VI
                             POST-CLOSING COVENANTS

       The parties agree as follows with respect to the period following the
Closing.

       SECTION 6.1. Further Assurances. In case at any time after the Closing
any further action is necessary or desirable to carry out the purposes of this
Agreement, Seller, on the one hand, and Buyer, on the other hand, will take such
further action (including the execution and delivery of such further instruments
and documents) as the other party reasonably may request, all at the sole cost
and expense of the requesting Party (unless the requesting Party is entitled to
indemnification therefor under Article VIII).

       SECTION 6.2. Cooperation. In the event and for so long as Seller, on the
one hand, or Buyer, on the other hand, actively is contesting or defending
against any action, suit, proceeding, hearing, investigation, charge, complaint,
claim or demand in connection with (a) any transactions contemplated by this
Agreement or (b) any fact, situation, circumstance, status, condition, activity,
practice, plan, occurrence, event, incident, action, failure to act or
transaction on or prior to the Closing Date involving any of the Assets or the
Business, the other Party will cooperate with such party and its counsel in the
contest or defense, make available their personnel (except to the extent that
making their personnel available unreasonably affects the ability of such
personnel to perform their normal duties), and provide such testimony and access
to their books and records as shall be reasonably necessary in connection with
the contest or defense, all at the sole cost and expense of the contesting or
defending Party (unless the contesting or defending Party is entitled to
indemnification therefor under Article VIII). The Parties also will cooperate
with each other in all reasonable respects to provide for the transition of the
operation of the Business to Buyer and the retention and operation of the
Network by Seller after the Closing, including reasonable cooperation regarding
access to accounting systems and other items.

       SECTION 6.3. Confidentiality. Buyer will treat and hold as confidential
all Confidential Information (except to the extent that the same relates to the
Assets or the Business) concerning Seller and its Affiliates, refrain from using
any such Confidential Information (except to the extent that the same relates to
the Assets or the Business) and deliver promptly to Seller or destroy, at the
request of Seller, all such Confidential Information (except to the extent that
the same relates to the Assets or the Business) in its possession. Seller will
treat and hold as confidential all Confidential Information concerning Buyer and
the Business or Assets, refrain from using any such Confidential Information and
deliver promptly to Buyer or destroy, at the request and option of Buyer, all of
such Confidential Information in its possession.

       SECTION 6.4. Resale Prospectus and Listing of Shares. In the event the
Resale Prospectus is not effective with the SEC as of the Closing, Buyer will
use its commercially reasonable best efforts to cause the Resale Prospectus to
become effective with the SEC as soon as possible after the Closing and to
maintain the effectiveness of the Resale Prospectus in accordance with the terms
thereof. Prior to or as of the effectiveness of the Resale Prospectus, the
Shares will be listed for trading on the NASDAQ.

       SECTION 6.5. Restriction on Distribution. During the period beginning on
the Closing Date and ending 18 months after the Closing Date, ICG will not
distribute to its shareholder, ICG Communications, Inc., or any Affiliate of ICG
Communications, Inc. that is not a subsidiary of or otherwise controlled by ICG,
any amounts attributable to the Purchase Price that it has received from Seller
after the Closing; provided that if at the end of such 18 month period Buyer has
pending claims for indemnification against Seller and ICG under Article VIII,
the restriction set forth in this Section 6.5 will continue to apply to the
extent of the amount of such pending claims until such claims are finally
resolved. ICG will not sell, assign or transfer any of its assets or properties
in any transaction in which ICG does not receive consideration of a reasonably
equivalent value for such assets or properties. ICG will not incur any liability
for borrowed money without receiving funds corresponding to such borrowing.

                     REMEDIES FOR BREACHES OF THIS AGREEMENT

       SECTION 8.1. Indemnification Provisions for Benefit of Buyer. If this
Agreement is not terminated prior to the Closing in accordance with Article IX,
and Seller breaches (a) any of the representations or warranties of Seller
contained herein or in the closing certificate delivered by Seller pursuant to
Section 7.1(g), and Buyer gives notice of a claim for indemnification against
Seller within the applicable Survival Period, or (b) any covenants or agreements
of Seller contained herein or in any Seller Document and Buyer gives notice
thereof to Seller, then, subject to Section 8.6, Seller and ICG, jointly and
severally, will indemnify, defend and hold harmless Buyer from and against any
Adverse Consequences Buyer may suffer arising out of or resulting from any of
the foregoing regardless of whether the Adverse Consequences are suffered 


                                      -30-
<PAGE>   36

during or after any applicable Survival Period. Subject to Section 8.6, Seller
and ICG, jointly and severally, also will indemnify, defend and hold harmless
Buyer from and against any Adverse Consequences Buyer may suffer, whether
suffered during or after the Survival Period, arising out of or resulting from
(c) any Liability against Buyer or any of the Assets by virtue of the
application of any bulk sales or other similar laws to the sale and transfer of
the Assets to Buyer, or failure of Seller to comply with any applicable bulk
sales laws or (d) any Liability of Seller other than an Assumed Liability, (e)
any Liability of Seller arising from or relating to the matters described in
Schedule 3.11(a) or (f) except as expressly set forth in this Agreement, any
Liability relating to the operation of the Business by Seller prior to the
Closing. In determining the amount of Adverse Consequences suffered by Buyer for
purposes of this Section 8.1 as a result of a breach by Seller described in
Section 8.1(a) or Section 8.1(b) above of any representation, warranty, covenant
or agreement of Seller qualified by the words "material," "materiality," "in all
material respects," "knowledge," "to the knowledge of," or words of similar
import, or by any phrase using any such terms or words, such Adverse
Consequences will be deemed to include only amounts that are material or arising
out of matters of which Seller or ICG had knowledge, as the case may be. If any
dispute arises concerning whether any indemnification is owing which cannot be
resolved by negotiation among the Parties within 30 days of notice of claim for
indemnification from the party claiming indemnification to the Party against
whom such claim is asserted, the dispute will be resolved by arbitration
pursuant to this Agreement.

       SECTION 8.2. Indemnification Provisions for Benefit of Seller. If this
Agreement is not terminated prior to the Closing in accordance with Article IX,
and Buyer breaches (a) any of its representations or warranties contained herein
or in the closing certificate delivered by Buyer pursuant to Section 7.2(c), and
Seller gives notice of a claim for indemnification against Buyer within the
applicable Survival Period, or (b) any covenants or agreements of Buyer
contained herein or in any Buyer Document and Seller gives notice thereof to
Buyer, then, subject to Section 8.6(d), Buyer will indemnify, defend and hold
harmless Seller from and against any Adverse Consequences Seller may suffer
arising out of or resulting from any of the foregoing regardless of whether the
Adverse Consequences are suffered during or after the applicable Survival
Period. In determining the amount of Adverse Consequences suffered by Seller for
purposes of this Section 8.2 as a result of a breach by Buyer described in
Sections 8.2(a) and 8.2(b) above of any representation, warranty, covenant or
agreement of Buyer qualified by the words "material," "materiality," "in all
material respects," "knowledge," "to the knowledge of," or words of similar
import, or by any phrase using any such terms or words, such Adverse
Consequences will be deemed to include only amounts that are material or arising
out of matters of which Buyer had knowledge, as the case may be. Subject to
Section 8.6(d), Buyer also will indemnify, defend and hold harmless Seller from
all Adverse Consequences Seller may suffer, whether suffered during or after the
Survival Period, (c) as a result of Buyer's failure to comply with any
applicable requirement under the WARN Act as required under Section 2.4(b)(i) or
(d) attributable to or arising out of the Assumed Liabilities, or from the
operation of the Business after the Closing. If any dispute arises concerning
whether any indemnification is owing which cannot be resolved by negotiation
among the Parties within 30 days of notice of claim for indemnification from the
Party claiming indemnification to the party against whom such claim is asserted,
the dispute will be resolved by arbitration pursuant to this Agreement.

       SECTION 8.3. Matters Involving Third Parties.

       (a)    If any Person not a party to this Agreement (including, without
limitation, any Governmental Authority) notifies Seller, on the one hand, or
Buyer, on the other hand, (the "Indemnified Party") with respect to any matter
(a "Third Party Claim") which may give rise to a claim for indemnification
against the Party (or in the case of Seller, Seller and ICG) (the "Indemnifying
Party"), then the Indemnified Party will notify the Indemnifying Party thereof
in writing within 15 days after receiving such notice. No delay on the part of
the Indemnified Party in notifying the Indemnifying Party will relieve the
Indemnifying Party from any obligation hereunder unless (and then solely to the
extent) the Indemnifying Party thereby is prejudiced by such delay.

       (b)    The Indemnifying Party will have the right, at its sole cost and
expense, to defend the Indemnified Party against the Third Party Claim with
counsel of its choice satisfactory to the Indemnified Party so long as (i) the
Indemnifying Party notifies the Indemnified Party in writing within ten days
after the Indemnified Party has given notice of the Third Party Claim that the
Indemnifying Party will indemnify the Indemnified Party from and against the
entirety of any Adverse Consequences for which the Indemnified Party is entitled
to indemnification, (ii) the Indemnifying Party provides the Indemnified Party
with evidence reasonably acceptable to the Indemnified Party that the
Indemnifying Party will have the financial resources to defend against the Third
Party Claim and fulfill its indemnification obligations hereunder, (iii) the
Third Party Claim involves only money damages and does not seek an injunction or
other equitable relief, (iv) settlement of, or an adverse judgment with respect
to, the Third Party Claim is not, in the good faith judgment of the Indemnified
Party, likely to establish a precedential custom or practice materially adverse
to the continuing business interests of the Indemnified Party, and (v) the
Indemnifying Party conducts the defense of the Third Party Claim actively and
diligently. At any time that the Indemnifying Party is entitled to conduct the
defense of the Third Party Claim in accordance with this Section 8.3(b), the
Indemnified Party may retain separate co-counsel at its sole cost and expense
and participate in the defense of the Third Party Claim. In the event any of the
conditions in this Section 8.3(b) is or becomes unsatisfied, the Indemnified
Party may defend against the Third Party Claim so long as the Indemnified Party
conducts the defense of the Third Party Claim actively and diligently.

       (c)    At any time that a party is defending a Third Party Claim, neither
party will consent to the entry of any judgment or enter into any settlement
with respect to the Third Party Claim without obtaining (A) an entry of
dismissal, with prejudice, or an entry of dismissal, without prejudice, and a
covenant not to sue (if legal action is instituted), (B) the full and
unconditional release of the other party from all liability in respect of such
Third Party Claim and (C) the prior written consent of the other party (not to
be withheld unreasonably).

       (d)    If the Indemnified Party has the right to and is in fact defending
the Third Party Claim, the Indemnifying Party will reimburse the Indemnified
Party promptly and periodically for the costs of defending against the Third
Party Claim (including reasonable attorneys' fees and 



                                      -32-
<PAGE>   38

expenses), and the Indemnifying Party will remain responsible for any Adverse
Consequences for which the Indemnified Party is entitled to indemnification.

       SECTION 8.4. Survival. The representations and warranties made in this
Agreement or in any other agreement referred to in this Agreement, or in any
certificate or other document delivered pursuant to this Agreement or in
connection with this Agreement will survive the Closing Date for a period of 18
months from the Closing Date, except that the representations and warranties of
Seller in Sections 3.8 and 3.13 will survive until the expiration of all
applicable statutes of limitations with respect to any such claims that could be
brought regarding such matters and the representations and warranties set forth
in Section 3.15 will survive the Closing Date for a period of five years from
the Closing Date. Neither Buyer, Seller nor ICG will have any obligation to
indemnify any Person pursuant to this Agreement with respect to any breach of a
representation or warranty after the applicable period set forth above. The
covenants and agreements of Seller and Buyer made in Article VI, and the
provisions of Articles VIII and X will survive the Closing Date indefinitely,
except as otherwise specifically provided herein.

       SECTION 8.5. Limitations.

       (a)    Subject solely to Section 9.2, the indemnification and other
provisions of this Article VIII will constitute the exclusive remedy by Seller,
on the one hand, and Buyer, on the other hand, against the other arising by
virtue of a breach of any agreement, representation, warranty, or covenant under
this Agreement. Notwithstanding anything to the contrary in this Agreement,
other than liability for specific performance under Section 9.2, Seller and ICG
will have no liability to Buyer, and Buyer will have no liability to Seller or
ICG, for any Adverse Consequences or other amounts in the event this Agreement
is terminated prior to the Closing in accordance with Article IX.

       (b)    Notwithstanding any provision in this Agreement to the contrary,
in no event will Seller or ICG, on the one hand, or Buyer, on the other hand, be
liable to the other for amounts attributable to lost profits, or consequential,
incidental, speculative or punitive damages (except to the extent such items are
payable to a Person not a Party to this Agreement).

       SECTION 8.6. Basket and Ceiling.

       (a)    Buyer will not be entitled to indemnification from Seller and ICG
under Section 8.1 or Section 8.3 unless and until the aggregate amount of
Adverse Consequences that Buyer would otherwise be entitled to assert under
either Section 8.1 or Section 8.3 exceeds One Million Dollars ($1,000,000) (the
"Basket Amount"). When the aggregate amount of such Adverse Consequences exceeds
the Basket Amount, Buyer will be entitled to indemnification under Section 8.1
or Section 8.3, as applicable, for all such Adverse Consequences and not just
those in excess of the Basket Amount.

       (b)    Subject to Section 8.6(a), Seller and ICG will be required to
indemnify Buyer under this Article VIII for all Adverse Consequences suffered as
a result of the breach of any of the representations, warranties or covenants
set forth in Article III or elsewhere in this 


                                      -33-

Agreement, other than the representations, warranties or covenants set forth in
any of Sections 3.8, 3.13 and 3.15 and the indemnification obligation set forth
in Section 8.1(e), only in an amount, in the aggregate for all or any of such
breaches, not in excess of 75 percent of the Purchase Price.

       (c)    Subject to Section 8.6(a), Seller and ICG will be required to
indemnify Buyer under this Article VIII for all Adverse Consequences suffered as
a result of one or more breaches of the representations and warranties set forth
in Sections 3.8, 3.13 and 3.15 and the indemnification obligation set forth in
Section 8.1(e), only in an amount, in the aggregate for all or any of such
breaches, not in excess of the Purchase Price.

       (d)    Buyer will be required to indemnify Seller under this Article VIII
for all Adverse Consequences suffered as a result of one or more breaches of the
representations, warranties or covenants set forth in Article IV or elsewhere in
00000this Agreement in an amount not in excess of the Purchase Price.

expected to result in, a Material Adverse Effect, Buyer has notified Seller of
the breach, and the breach has not been cured within 30 days after the notice of
breach (unless the representation, warranty or covenant failure results
primarily from Buyer breaching any agreement contained in this Agreement in any
material way); or (ii) if the Closing has not occurred on or before 180 days
following the date of this Agreement becase of the failure of any condition
precedent to Buyer's obligations to consummate the Closing; or

Buyer at any time prior to the Closing (i) if Buyer has materially breached any
agreement, representation, warranty or covenant contained in this Agreement,
Seller has notified Buyer of the breach, and the breach has not been cured
within 30 days after the notice of breach (unless the failure results primarily
from Seller or ICG breaching any agreement, representation, warranty or covenant
contained in this Agreement in any material way) or (ii) if the Closing has not
occurred on or before 180 days following the date of this Agreement because of
the failure of any condition precedent to Seller's or ICG's obligations to
consummate the Closing.

agrees that the other Party could not be adequately compensated by its remedies
at law.

       SECTION 9.3. Confidentiality. If this Agreement is terminated, each Party

arise favoring or disfavoring any party by virtue of the authorship of any of
the provisions of this Agreement. The parties intend that each representation,
warranty and covenant contained herein will have independent significance. If
any party breaches any representation, warranty or covenant contained herein in
any respect, the fact that there exists another representation, warranty or
covenant relating to the same subject matter (regardless of the relative levels
of specificity) which the party has not breached will not detract from or
mitigate the fact that the party is in breach of the first representation,
warranty or covenant.

       SECTION 10.13. Incorporation of Exhibits and Schedules. The Exhibits and
Schedules identified in this Agreement are incorporated herein by reference and
made a part hereof.

       SECTION 10.14. Representations as to Knowledge. Except as otherwise
provided in this Agreement, the representations and warranties contained in
Article III and Article IV will, in each and every case where a statement to the
"knowledge" is required on behalf of any Party to this Agreement, be deemed to
require that such statement be in good faith after reasonable investigation.

                               CLOSING AGREEMENT


     Reference is made to the Asset Purchase Agreement dated as of January 5, 
1999 by and between MindSpring Enterprises, Inc., a Delaware corporation 
("MindSpring"), and NETCOM On-Line Communication Services, Inc. ("NETCOM"), a 
Delaware corporation (the "Purchase Agreement").  Capitalized terms used herein 
that have been defined in the Purchase Agreement shall have the same meanings 
as in the Purchase Agreement.

     In consideration of the mutual promises set forth in this Closing 
Agreement and in the Purchase Agreement, the parties agree as follows with 
respect to the following matters:

     1.   NETCOM and MindSpring agree to prorate and allocate, for periods 
before and after the Closing, all property taxes, special taxes and assessments 
attributable to the calendar year in which the Closing occurs and amounts 
payable under equipment leases, outsourcing contracts and other contracts to be 
transferred and assumed by MindSpring as of the Closing.  Thus, in furtherance 
thereof, for purposes of prorating and allocating, as between NETCOM and 
MindSpring, all property taxes, ad valorem taxes and special taxes or 
assessments attributable to the Assets for periods prior to and after the 
Closing that are identified on SCHEDULE A, and other amounts identified on 
SCHEDULE A that are payable in connection with obligations to be assumed by 
MindSpring as of the Closing (together, the "Expenses") MindSpring will remit 
to NETCOM in cash the amount of the net Expenses as set forth on the attached 
SCHEDULE A within ten days after the Closing.  If the amounts actually paid 
with respect to the amounts identified as estimates on SCHEDULE A differ from 
the amounts of such estimates, MindSpring or NETCOM, as the case may be, as 
appropriate, will promptly pay the difference to the other.

     2.   For purposes of allocating the monthly subscriber payments actually 
received by NETCOM during the month of February 1999 on account of dial-up, 
dedicated and Web-hosting services billed by NETCOM in February 1999 prior to 
the Closing and to be provided to Subscribers by NETCOM during February 1999 
prior to the Closing and by MindSpring during February 1999 after the Closing, 
other than amounts received from Subscribers for prepaid services (the 
"Subscriber Payments"), NETCOM will remit to MindSpring in cash the amount of 
the Subscriber Payments set forth on SCHEDULE A within ten days after the 
Closing.  Such amount will be determined in accordance with the methodology 
described in SCHEDULE B and shall represent that portion of the Subscriber 
Payments that is applicable to the period in February following the Closing 
Date as determined on a ratable daily basis, but shall not include any amounts 
paid to or previously received by NETCOM pursuant to any prepaid contracts. 
NETCOM represents and warrants to MindSpring that the amount set forth on 
SCHEDULE A as the total Subscriber Payments received during the month of 
February 1999 was calculated based on the methodology set forth in SCHEDULE B 
and is a reasonable estimate of the Subscriber Payments collected by NETCOM as 
of February 15.  Within 10 days after the Closing, NETCOM will confirm to 
MindSpring, based on the methodology set forth in SCHEDULE B, the amount of 
Subscriber Payments received prior to the Closing.  If the amount of such 
confirmed Subscriber Payments differs from the total amount of Subscriber 
Payments set forth on SCHEDULE A, the amount payable by NETCOM to MindSpring 
will be adjusted appropriately.  The amount payable by NETCOM to MindSpring 
under this paragraph 2 shall be reduced by the amount of the Severance Estimate 
as set forth in paragraph 6.
<PAGE>   2
     3.   Attached hereto as SCHEDULE C are the final schedules to the Purchase 
Agreement as contemplated by Section 2.1(c) of the Purchase Agreement. These 
schedules include the master list of all NETCOM contracts previously provided 
to MindSpring and the list of contracts the status of which is to be determined 
after the Closing, the final schedule of intellectual property, the final 
master employee list (the "Employee Schedule") and the final schedule of the 
inventory of tangible personal property.

     4.   SCHEDULE D sets forth two lists of contracts. The contracts 
identified in the "Accept" column of the attached SCHEDULE D as "No" are the 
contracts described on Schedule 1.1(iii) to the Purchase Agreement that are (i) 
contracts involving bounty payments of $50 or more per Subscriber, (ii) 
contracts involving the payment of monthly recurring revenue, or (iii) 
contracts involving annual payments, in cash or in kind, in excess of One 
Hundred Thousand Dollars ($100,000) per annum, that Buyer elects pursuant to 
the Purchase Agreement to exclude from the definition of "Assets." The contracts
identified in the "Accept" column of the attached Schedule D as "TBD" or 
otherwise designated in Schedule D as "to be determined" are contracts the 
status of which are not yet agreed by MindSpring and NETCOM. MindSpring and 
NETCOM will cooperate on a reasonable basis after the Closing to determine, 
such determination to be made within 30 days after the Closing, whether such 
"to be determined" contracts are to be included in the definition of Assets 
under the Asset Purchase Agreement and transferred to MindSpring as of the 
Closing.

     5.   Attached hereto as SCHEDULE E pursuant to Section 2.4(b)(ii) of the 
Purchase Agreement is a list of executive officers of NETCOM that will not be 
employed by MindSpring after the Closing.

     6.   NETCOM agrees to pay in connection with the Closing, accrued and 
previously unpaid bonuses and vacation pay (including a one-day floating 
holiday for non-California employees, in the approximate amount of $31,625 plus 
applicable payroll taxes) to the NETCOM employees listed on the Employee 
Schedule as employees to be laid off (the "Laid Off Employees") or employed by 
MindSpring, provided that MindSpring will reimburse NETCOM, in cash within 10 
days after the Closing, all amounts attributable to the one-day floating 
holiday for non-California employees included as part of such employees. As an 
accommodation to MindSpring, in lieu of MindSpring offering employment in 
accordance with Section 2.4(b)(i) of the Purchase Agreement, NETCOM, at 
MindSpring's expense, will terminate the employment of the Laid Off Employees 
and pay to or on behalf of such Persons wages and salaries for the period after 
the Closing and severance pay (including, without duplication, payroll taxes 
required to be withheld and/or paid on behalf of the employee and the employer 
and other required amounts with respect to such wages and salaries). After the 
Closing, NETCOM will have no obligation to or with respect to the Laid Off 
Employees (including with respect to or furtherance of such termination) except 
as required in writing by MindSpring and at MindSpring's sole expense. If the 
total amount payable by NETCOM to MindSpring pursuant to paragraph 2 (as such 
amount is determined without regard to the last sentence of such paragraph 2) 
is less than One Million Six Hundred Seventy-Four Thousand Dollars ($1,674,000) 
(the "Severance Estimate"), MindSpring will pay to NETCOM in cash within 10 
days of the Closing the amount of the difference. If the amount actually 
payable by NETCOM to the Laid Off Employees pursuant to this Section 6 differs
from the Severance Estimate, NETCOM or MindSpring, as the case may be, as
appropriate, promptly will pay to the other in cash an amount equal to such
difference. MindSpring will indemnify, defend and hold harmless NETCOM from and
against any Adverse Consequences NETCOM may suffer, including those arising
under the WARN Act, arising out of or resulting from the termination of the
employment of the Laid Off Employees regardless of whether


                                       2
<PAGE>   3
such Adverse Consequences are suffered during or after the Survival Period. As 
a further accommodation to MindSpring, NETCOM agrees that for a reasonable 
period after the Closing as agreed by the parties it will maintain on its 
payroll the employees that are employed under H-1 Visas as of the Closing that 
are listed on SCHEDULE F (the "Visa Employees"). MindSpring agrees to promptly 
reimburse NETCOM for all salary and benefits (including payroll taxes) and 
reasonable out-of-pocket costs incurred by NETCOM following the Closing with 
respect to the Visa Employees. Upon the payment by NETCOM of the vacation pay 
and bonuses as required under this paragraph 6, NETCOM shall have no obligation 
to pay to MindSpring the Five Hundred Thousand Dollar ($500,000) payment for 
vacation pay under Section 2.4(b)(iii) of the Purchase Agreement or to make any 
other reimbursement or payment to MindSpring under Section 2.4(b)(iii) on 
account of any vacation pay or bonuses, including the One Million Two Hundred 
Thousand Dollar ($1,200,000) reimbursement for bonuses.

     7.   MindSpring agrees that it will compensate NETCOM under the Network 
Services Agreement to be entered into by the Parties as of the Closing in 
accordance with the terms thereof for the period in February 1999 following the 
Closing, and thus MindSpring will pay to NETCOM the fees payable under Section 3
of the Network Services Agreement in an amount equal to 12/28ths of the fees 
that would have been payable under such Section 3 if the Closing had occurred 
at 12:01 a.m. Pacific Standard Time on February 1, 1999 and the Network 
Services Agreement had come into effect as of such time.

     8.   This Closing Agreement shall constitute an amendment to the Purchase 
Agreement to the extent of the foregoing matters addressed herein. The Purchase 
Agreement as so amended by this Closing Agreement shall remain in full force 
and effect.

     9.   This Closing Agreement may be executed in couterparts. Each of such 
counterparts shall be deemed to be an original, but all of such counterparts 
together shall constitute one and the same agreement. This Closing Agreement 
may be delivered by facsimile.

     10.  MindSpring will cooperate with NETCOM on a reasonable basis to 
minimize NETCOM's liability to third parties with respect to the contracts 
described on SCHEDULE D that are not included within the definition of 
"Assets." In furtherance thereof, in addition to other actions that may be 
reasonably requested by NETCOM, upon the receipt by MindSpring from NETCOM of 
applicable registration codes and the names of the applicable third party 
contracts, MindSpring will turn off or disconnect such registration codes. 
MindSpring will assist NETCOM on a reasonable basis in identifying the 
applicable registration codes for such contracts.

     11.  The Assets will not include, and MindSpring will obtain no benefit or 
assume any liability thereunder, for the following contracts: (i) Systems Union 
Maintenance; (2) ASAP: Support for Lotus Notes; and (3) Qualcomm Eudora License 
(in retail boxes). These contracts will constitute part of the Retained Assets.

     12.  MindSpring and NETCOM acknowledge that as of the date of this Closing 
Agreement, consent from the landlord to the assignment of NETCOM's office lease 
(the "Lease") with Horizon Center LLC (the "Consent") has not been received. 
Pursuant to Section 2.1(d) of the Asset Purchase Agreement, until such time as 
the Consent is received NETCOM shall make the benefits of the Lease available 
to MindSpring, and MindSpring shall perform all obligations of the tenant under 
the Lease (but not including any obligations arising as a result of the failure 
to obtain the Consent). All costs incurred by NETCOM in


                                       3
<PAGE>   4
performing its obligations under this Section 12 shall be borne by NETCOM to 
the extent that those costs exceed the costs which would have been incurred by 
tenant under the Lease had the Consent been received.  As of and from the 
Closing and until the time the Consent is received, MindSpring will reimburse 
NETCOM for the costs it incurs in connection with the Lease to the extent that 
such costs do not exceed the costs which would have been incurred by tenant 
under the Lease had the Consent been received.  NETCOM's obligations under this 
Section 12 shall not be deemed to limit NETCOM's other obligations with 
respect to the Consent under Section 2.1(d) of the Asset Purchase Agreement.

      SECTION 2.1       Loans.  Subject to the terms and conditions of this
Agreement, each Lender severally agrees to make Loans to the Borrower from time
to time from the Closing Date through the Termination Date as requested by the
Borrower in accordance with the terms of Section 2.2; provided, that (a) the
aggregate principal amount of all outstanding Loans (after giving effect to any
amount requested) shall not exceed the lesser of (i) the Available Commitment
or (ii) the Aggregate Commitment, in each case, less the sum of all outstanding
L/C Obligations and (b) the principal amount of outstanding Loans from any

less such Lender's Commitment Percentage of outstanding L/C Obligations.  Each
Loan by a Lender shall be in a principal amount equal to such Lender's

substantially in the form of Exhibit C hereto (a "Notice of Account
Designation") delivered by the Borrower to the Administrative Agent or may be

outstanding principal amount of all Loans in full on the Termination Date, with
all accrued but unpaid interest thereon.

      (b)     Mandatory Repayment of Excess Loans.  If at any time the
outstanding principal amount of all Loans exceeds the lesser of (i) the
Available Commitment or (ii) the Aggregate Commitment, less, in each case, the
sum of all outstanding L/C Obligations, the Borrower shall (i) repay the Loans
immediately upon notice from the Administrative Agent, by payment to the
Administrative Agent for the account of the Lenders or (ii) furnish cash
collateral reasonably satisfactory to the Administrative Agent and/or repay the
L/C Obligations in an amount equal to such excess.  Such cash collateral shall
be applied in accordance with Section 11.2(b).  Each such repayment shall be
accompanied by any amount required to be paid pursuant to Section 4.9 hereof.

      (c)     Optional Repayments.  The Borrower may at any time and from time
to time repay the Loans, in whole or in part, upon at least three (3) Business
Days' irrevocable notice to the Administrative Agent with respect to LIBOR Rate
Loans and one (1) Business Day irrevocable notice with respect to Base Rate
Loans in the form attached hereto as Exhibit D (a "Notice of Prepayment")
specifying the date and amount of repayment and whether the repayment is of
LIBOR Rate Loans or Base Rate Loans or a combination thereof, and, if of a
combination thereof, the amount allocable to each.  Upon receipt of such
notice, the Administrative Agent shall promptly notify each Lender.  If any
such notice is given, the amount 

                                      14

not repay any LIBOR Rate Loan on any day other than on the last day of the
Interest Period applicable thereto unless such repayment is accompanied by any
amount required to be paid pursuant to Section 4.9 hereof.

      SECTION 2.4    Notes.  Each Lender's Loans and the obligation of the
Borrower to repay such Loans shall be evidenced by a separate Note executed by
the Borrower payable to the order of such Lender representing the Borrower's
obligation to pay such Lender's Commitment or, if less, the aggregate unpaid
principal amount of all Loans made and to be made by such Lender to the
Borrower hereunder, plus interest and all other fees, charges and other amounts
due thereon.  Each Note shall be dated the date hereof and shall bear interest
on the unpaid principal amount thereof at the applicable interest rate per
annum specified in Section 4.1.

      SECTION 2.5       Permanent Reduction of the Aggregate Commitment.

      (a)     Voluntary Permanent Reduction.  The Borrower shall have the right

portions of the Aggregate Commitment, from time to time, in an aggregate
principal amount not less than $3,000,000 or any whole multiple of $1,000,000
in excess thereof.

      (b)     Mandatory Permanent Reductions.  The Aggregate Commitment and the
Available Commitment shall be permanently reduced by the following amounts on
the corresponding dates as follows:

              (i)      Insurance Proceeds.  One hundred percent (100%) of Net
Cash Proceeds received by the Borrower or any Subsidiary thereof in excess of
$1,000,000 in the aggregate during any twelve (12) month period or $5,000,000 in
the aggregate during the term of this Agreement under any policy of insurance;
provided, that so long as no Default or Event of Default then exists, such Net
Cash Proceeds may be used to finance the repair or replacement of damaged assets
or to purchase like assets within one hundred and twenty days (120) after
receipt thereof;

              (ii)     Sale of Assets.  One hundred percent (100%) of Net Cash
Proceeds received by the Borrower or any Subsidiary thereof in connection with
the sale of assets (other than a sale of assets permitted pursuant to Sections
10.6(a)-(d)); provided, that so long as no Default or Event of Default then
exists, such Net Cash Proceeds may be used to purchase like assets within one
hundred and twenty (120) days after receipt thereof; and


                                      15
<PAGE>   21


               (iii)    Proceeds from Debt Offerings.  One hundred percent
(100%) of Net Cash Proceeds from any Debt issued by the Borrower or any
Subsidiary thereof within three (3) Business Days of receipt thereof by the

      (c)      Additional Payments.  Each permanent reduction permitted or
required pursuant to this Section 2.5 shall be accompanied by a payment of
principal sufficient to reduce the aggregate outstanding Extensions of Credit
of the Lenders after such reduction to the Aggregate Commitment as so reduced
and if the Aggregate Commitment as so reduced is less than the aggregate amount
of all outstanding Letters of Credit, the Borrower shall be required to deposit
in a cash collateral account opened by the Administrative Agent an amount equal
to the aggregate then undrawn and unexpired amount of such Letters of Credit.
Any reduction of the Aggregate Commitment to zero shall be accompanied by
payment of all outstanding Obligations (and furnishing of cash collateral
satisfactory to the Administrative Agent for all L/C Obligations) and shall
result in the termination of the Commitments and Credit Facility.  Such cash
collateral shall be applied in accordance with Section 11.2(b).  If the
reduction of the Aggregate Commitment requires the repayment of any LIBOR Rate
Loan, such repayment shall be accompanied by any amount required to be paid
pursuant to Section 4.9 hereof.

      SECTION 2.6       Termination of Credit Facility.  The Credit Facility
shall terminate on the earliest of (a) February 17, 2002, (b) the date of
termination by the Borrower pursuant to Section 2.5, and (c) the date of
termination by the Administrative Agent on behalf of the Lenders pursuant to
Section 11.2(a).

of the Extensions of Credit (a) to finance Permitted Acquisitions pursuant to
Section 10.4(c), (b) to finance the Netcom Acquisition, and (c) for working

Subsidiaries, including the payment of certain fees and expenses incurred in

consent of the Required Lenders to increase the total amount of the Aggregate
Commitments hereunder by (a) first, accepting the offer of any existing Lender
or Lenders to increase its (or their) Commitment (or Commitments) up to the
amount of any such increase (which increase shall be offered first to the
Administrative Agent, then (to the extent any such increase is not fully
underwritten by the Administrative Agent) to the existing other Lenders); and/or
(b) second, accepting the offer or offers of any Person or Persons (not then a
Lender) constituting an Eligible Assignee to become a new Lender hereto with a
Commitment or Commitments up to the amount (or aggregate amount) of any such
increase to the extent any such increase is not fully underwritten by the
Administrative Agent or existing Lenders; provided, that (i) in no event shall
any Lender's Commitment be increased without the consent of such Lender, (ii) if
any Loans are outstanding hereunder on the date that any such increase is to
become effective, the Administrative Agent shall make such transfers of funds as
are necessary in order that the outstanding balance of such Loans reflect the
Commitment Percentages of the Lenders after giving effect to any increase
pursuant to this Section 2.8, (iii) 

                                      16
<PAGE>   22



each such increase shall be in minimum amounts of at least Five Million Dollars
($5,000,000) and (iv) in no event shall any such increase result in the amount
of the Aggregate Commitment exceeding $200,000,000.  Any increase to the
Aggregate Commitment pursuant to clause (a) of the first sentence of this
Section 2.8 shall become effective upon the execution of a Commitment Increase
Supplement in the form of Exhibit I-1 hereto, executed by the Borrower, the
Administrative Agent and the increasing Lender or Lenders and any increase to

Section 2.8 shall become effective upon the execution of a New Lender Supplement

      SECTION 3.1       L/C Commitment.  Subject to the terms and conditions

Issuing Lender shall have no obligation to issue any Letter of Credit if, after

of Credit shall (i) be denominated in Dollars in a minimum amount of $500,000,
(ii) be a standby letter of credit issued to support obligations of the
Borrower or any of its Subsidiaries, contingent or otherwise, incurred in the
ordinary course of business, (iii) expire on a date reasonably satisfactory to
the Issuing Lender, which date shall be no later than the Termination Date and
(iv) be subject to the Uniform Customs and, to the extent not inconsistent
therewith, the laws of the State of North Carolina.  The Issuing Lender shall
not at any time be obligated to issue any Letter of Credit hereunder if such
issuance would conflict with, or cause the Issuing Lender or any L/C Participant
to exceed any limits imposed by any Applicable Law.  References herein to
"issue" and derivations thereof with respect to Letters of Credit shall also
include extensions or modifications of any existing Letters of Credit, unless
the context otherwise requires.

of Credit by delivering to the Issuing Lender at the Administrative Agent's

Lender, and such other certificates, documents and other papers and information
as the Issuing Lender may request.  Upon receipt of any Application, the
Issuing Lender shall process such Application and the certificates, documents
and other papers and information delivered to it in connection therewith in

Article V hereof, promptly issue the Letter of Credit 

                                      17
<PAGE>   23



requested thereby (but in no event shall the Issuing Lender be required to issue
any Letter of Credit earlier than three (3) Business Days after its receipt of
the Application therefor and all such other certificates, documents and other
papers and information relating thereto) by issuing the original of such Letter
of Credit to the beneficiary thereof or as otherwise may be agreed by the
Issuing Lender and the Borrower.  The Issuing Lender shall promptly furnish to
the Borrower a copy of such Letter of Credit and promptly notify each Lender of
the issuance and upon request by any Lender, furnish to such Lender a copy of
such Letter of Credit and the amount of such Lender's participation therein.

      SECTION 3.3       Commissions and Other Charges.

      (a)     The Borrower shall pay to the Administrative Agent, for the
account of the Issuing Lender and the L/C Participants, a letter of credit
commission with respect to each Letter of Credit in an amount equal to the face
amount of such Letter of Credit multiplied by the Applicable Margin for LIBOR
Rate Loans (determined on a per annum basis).  Such commission shall be payable
quarterly in arrears on the last Business Day of each calendar quarter and on
the Termination Date.

      (b)     In addition to the foregoing commission, the Borrower shall pay
the Issuing Lender and the Letter of Credit Participants an issuance fee of
0.125% percent per annum on the face amount of each Letter of Credit, payable
quarterly in arrears on the last Business Day of each calendar quarter and on
the Termination Date.

      (c)     The Administrative Agent shall, promptly following its receipt
thereof, distribute to the Issuing Lender and the L/C Participants all
commissions received by the Administrative Agent in accordance with their
respective Commitment Percentages.

      SECTION 3.4       L/C Participations.

      (a)     The Issuing Lender irrevocably agrees to grant and hereby grants
to each L/C Participant, and, to induce the Issuing Lender to issue Letters of
Credit hereunder, each L/C Participant irrevocably agrees to accept and purchase
and hereby accepts and purchases from the Issuing Lender, on the terms and
conditions hereinafter stated, for such L/C Participant's own account and risk
an undivided interest equal to such L/C Participant's Commitment Percentage in
the Issuing Lender's obligations and rights under each Letter of Credit issued
hereunder and the amount of each draft paid by the Issuing Lender thereunder. 
Each L/C Participant unconditionally and irrevocably agrees with the Issuing
Lender that, if a draft is paid under any Letter of Credit for which the Issuing
Lender is not reimbursed in full by the Borrower in accordance with the terms of
this Agreement, such L/C Participant shall pay to the Issuing Lender upon demand
at the Issuing Lender's address for notices specified herein an amount equal to
such L/C Participant's Commitment Percentage of the amount of such draft, or any
part thereof, which is not so reimbursed.

      (b)     Upon becoming aware of any amount required to be paid by any L/C
Participant to the Issuing Lender pursuant to Section 3.4(a) in respect of any
unreimbursed portion of any payment made by the Issuing Lender under any Letter
of Credit, the Issuing Lender shall notify 


                                      18
<PAGE>   24


each L/C Participant of the amount and due date of such required payment and
such L/C Participant shall pay to the Issuing Lender the amount specified on the
applicable due date.  If any such amount is paid to the Issuing Lender after the
date such payment is due, such L/C Participant shall pay to the Issuing Lender
on demand, in addition to such amount, the product of (i) such amount, times
(ii) the daily average Federal Funds Rate as determined by the Administrative
Agent during the period from and including the date such payment is due to the
date on which such payment is immediately available to the Issuing Lender, times
(iii) a fraction the numerator of which is the number of days that elapse during
such period and the denominator of which is 360.  A certificate of the Issuing
Lender with respect to any amounts owing under this Section 3.4(b) shall be
conclusive in the absence of manifest error.  With respect to payment to the
Issuing Lender of the unreimbursed amounts described in this Section 3.4(b), if
the L/C Participants receive notice that any such payment is due (A) prior to
1:00 p.m. (Charlotte time) on any Business Day, such payment shall be due that
Business Day, and (B) after 1:00 p.m. (Charlotte time) on any Business Day, such
payment shall be due on the following Business Day.

      (c)     Whenever, at any time after the Issuing Lender has made payment
under any Letter of Credit and has received from any L/C Participant its
Commitment Percentage of such payment in accordance with this Section 3.4, the
Issuing Lender receives any payment related to such Letter of Credit (whether
directly from the Borrower or otherwise) or any payment of interest on account
thereof, the Issuing Lender will distribute to such L/C Participant its pro
rata share thereof; provided, that in the event that any such payment received
by the Issuing Lender shall be required to be returned by the Issuing Lender,
such L/C Participant shall return to the Issuing Lender the portion thereof
previously distributed by the Issuing Lender to it.

      SECTION 3.5       Reimbursement Obligation of the Borrower. The Borrower
agrees to reimburse the Issuing Lender on each date on which the Issuing Lender
notifies the Borrower of the date and amount of a draft paid under any Letter
of Credit for the amount of (a) such draft so paid and (b) any taxes, fees,
charges or other costs or expenses incurred by the Issuing Lender in connection
with such payment.  Each such payment shall be made to the Issuing Lender at
its address for notices specified herein in lawful money of the United States
and in immediately available funds.  Interest shall be payable on any and all
amounts remaining unpaid by the Borrower under this Article III from the date
such amounts become payable (whether at stated maturity, by acceleration or
otherwise) until payment in full at the rate which would be payable on any
outstanding Base Rate Loans which were then overdue.  If the Borrower fails to
timely reimburse the Issuing Lender on the date the Borrower receives the notice
referred to in this Section 3.5, the Borrower shall be deemed to have timely
given a Notice of Borrowing hereunder to the Administrative Agent requesting the
Lenders to make a Base Rate Loan on such date in an amount equal to the amount
of such drawing and, regardless of whether or not the conditions precedent
specified in Article V have been satisfied, the Lenders shall make Base Rate
Loans in such amount, the proceeds of which shall be applied to reimburse the
Issuing Lender for the amount of the related drawing and costs and expenses.

      SECTION 3.6       Obligations Absolute.  The Borrower's obligations under
this Article III (including without limitation the Reimbursement Obligation)
shall be absolute and unconditional under any and all circumstances and
irrespective of any set-off, counterclaim or defense to payment which the
Borrower may have or have had against the Issuing Lender or any 

                                      19
<PAGE>   25



beneficiary of a Letter of Credit.  The Borrower also agrees with the Issuing
Lender that the Issuing Lender shall not be responsible for, and the Borrower's
Reimbursement Obligation under Section 3.5 shall not be affected by, among other
things, the validity or genuineness of documents or of any endorsements thereon,
even though such documents shall in fact prove to be invalid, fraudulent or
forged, or any dispute between or among the Borrower and any beneficiary of any
Letter of Credit or any other party to which such Letter of Credit may be
transferred or any claims whatsoever of the Borrower against any beneficiary of
such Letter of Credit or any such transferee.  The Issuing Lender shall not be
liable for any error, omission, interruption or delay in transmission, dispatch
or delivery of any message or advice, however transmitted, in connection with
any Letter of Credit, except for errors or omissions caused by the Issuing
Lender's gross negligence or willful misconduct.  The Borrower agrees that any
action taken or omitted by the Issuing Lender under or in connection with any
Letter of Credit or the related drafts or documents, if done in the absence of
gross negligence or willful misconduct and in accordance with the standards of
care specified in the Uniform Customs and, to the extent not inconsistent
therewith, the UCC shall be binding on the Borrower and shall not result in any
liability of the Issuing Lender to the Borrower.  The responsibility of the
Issuing Lender to the Borrower in connection with any draft presented for
payment under any Letter of Credit shall, in addition to any payment obligation
expressly provided for in such Letter of Credit, be limited to determining that
the documents (including each draft) delivered under such Letter of Credit in
connection with such presentment are in conformity with such Letter of Credit.

      SECTION 3.7       Effect of Application.  To the extent that
any provision of any Application related to any Letter of Credit is
inconsistent with the provisions of this Article III, the provisions of this
Article III shall apply.

                                   ARTICLE IV

                            GENERAL LOAN PROVISIONS

      SECTION 4.1       Interest.

      (a)     Interest Rate Options.  Subject to the provisions of this Section
4.1, at the election of the Borrower, the aggregate principal balance of the
Notes or any portion thereof shall bear interest at (A) the Base Rate plus the
Applicable Margin as set forth in Section 4.1(c) or (B) the LIBOR Rate plus the
Applicable Margin as set forth in Section 4.1(c); provided that the LIBOR Rate
shall not be available until three (3) Business Days after the Closing Date.
The Borrower shall select the rate of interest and Interest Period, if any,
applicable to any Loan at the time a Notice of Borrowing is given pursuant to
Section 2.2 or at the time a Notice of Conversion/Continuation is given
pursuant to Section 4.2.  Each Loan or portion thereof bearing interest based
on the Base Rate shall be a "Base Rate Loan", each Loan or portion thereof
bearing interest based on the LIBOR Rate shall be a "LIBOR Rate Loan."  Any
Loan or any portion thereof as to which the Borrower has not duly specified an
interest rate as provided herein shall be deemed a Base Rate Loan.

      (b)     Interest Periods.  In connection with each LIBOR Rate Loan, the
Borrower, by giving notice at the times described in Section 4.1(a), shall
elect an interest period (each, an "Interest Period") to be applicable to such
Loan, which Interest Period shall be a period of one (1), two (2), three (3),
or six (6) months with respect to each LIBOR Rate Loan; provided that:

               (i)         the Interest Period shall commence on the date of
advance of or conversion to any LIBOR Rate Loan and, in the case of immediately
successive Interest Periods, each successive Interest Period shall commence on
the date on which the next preceding Interest Period expires;

               (ii)        if any Interest Period would otherwise expire on a
day that is not a Business Day, such Interest Period shall expire on the next
succeeding Business Day; provided, that if any Interest Period with respect to
a LIBOR Rate Loan would otherwise expire on a day that is not a Business Day
but is a day of the month after which no further Business Day occurs in such
month, such Interest Period shall expire on the next preceding Business Day;

               (iii)       any Interest Period with respect to a LIBOR Rate
Loan that begins on the last Business Day of a calendar month (or on a day for
which there is no numerically corresponding day in the calendar month at the
end of such Interest Period) shall end on the last Business Day of the relevant
calendar month at the end of such Interest Period;

               (iv)        no Interest Period shall extend beyond the
Termination Date; and

               (v)         there shall be no more than five (5) Interest
Periods outstanding at any time.

      (c)     Applicable Margin.  The Applicable Margin provided for in Section
4.1(a) with respect to the Loans (the "Applicable Margin") shall (i) from the
Closing Date until the delivery of the Officer's Compliance Certificate and
related financial statements for the fiscal quarter ending on March 31, 1999,
equal Level I pricing and (ii) for each fiscal quarter thereafter be determined
by reference to the Leverage Ratio as of the end of the fiscal quarter
immediately preceding the delivery of the applicable Officer's Compliance
Certificate as follows:

</TABLE>

Adjustments, if any, in the Applicable Margin shall be made by the
Administrative Agent on the fifth (5th) Business Day after receipt by the
Administrative Agent of quarterly financial statements for the Borrower and its
Subsidiaries and the accompanying Officer's Compliance Certificate setting
forth the Leverage Ratio of the Borrower and its Subsidiaries as of the most
recent fiscal quarter end.  Subject to Section 4.1(d), in the event the
Borrower fails to deliver such financial statements and certificate within the
time required by Sections 7.1 and 7.2, the Applicable Margin shall be the
highest Applicable Margin set forth above until the delivery of such financial
statements and certificate.


                                      21
<PAGE>   27


      (d)     Default Rate.  Subject to Section 11.3, at the discretion of the
Administrative Agent and the Required Lenders, upon the occurrence and during
the continuance of an Event of Default, (i) the Borrower shall no longer have
the option to request LIBOR Rate Loans, (ii) all outstanding LIBOR Rate Loans
shall bear interest at a rate per annum two percent (2%) in excess of the rate
then applicable to LIBOR Rate Loans, as applicable, until the end of the
applicable Interest Period and thereafter at a rate equal to two percent (2%)
in excess of the rate then applicable to Base Rate Loans, and (iii) all
outstanding Base Rate Loans shall bear interest at a rate per annum equal to
two percent (2%) in excess of the rate then applicable to Base Rate Loans.
Interest shall continue to accrue on the Notes after the filing by or against
the Borrower of any petition seeking any relief in bankruptcy or under any act
or law pertaining to insolvency or debtor relief, whether state, federal or
foreign.

      (e)     Interest Payment and Computation.  Interest on each Base Rate
Loan shall be payable in arrears on the last Business Day of each calendar
quarter commencing March 31, 1999; and interest on each LIBOR Rate Loan shall
be payable on the last day of each Interest Period applicable thereto, and if
such Interest Period extends over three (3) months, at the end of each three
(3) month interval during such Interest Period.  Interest on LIBOR Rate Loans
and all fees payable hereunder shall be computed on the basis of a 360-day year
and assessed for the actual number of days elapsed and interest on Base Rate
Loans shall be computed on the basis of a 365/66-day year and assessed for the
actual number of days elapsed.

      (f)     Maximum Rate.  In no contingency or event whatsoever shall the
aggregate of all amounts deemed interest hereunder or under any of the Notes
charged or collected pursuant to the terms of this Agreement or pursuant to any
of the Notes exceed the highest rate permissible under any Applicable Law which
a court of competent jurisdiction shall, in a final determination, deem
applicable hereto.  In the event that such a court determines that the Lenders
have charged or received interest hereunder in excess of the highest applicable
rate, the rate in effect hereunder shall automatically be reduced to the maximum
rate permitted by Applicable Law and the Lenders shall at the Administrative
Agent's option (i) promptly refund to the Borrower any interest received by
Lenders in excess of the maximum lawful rate or (ii) shall apply such excess to
the principal balance of the Obligations.  It is the intent hereof that the
Borrower not pay or contract to pay, and that neither the Administrative Agent
nor any Lender receive or contract to receive, directly or indirectly in any
manner whatsoever, interest in excess of that which may be paid by the Borrower
under Applicable Law.

      SECTION 4.2       Notice and Manner of Conversion or Continuation
of Loans.  Provided that no Event of Default has occurred and is then
continuing, the Borrower shall have the option to (a) convert at any time
following the third Business Day after the Closing Date all or any portion of
its outstanding Base Rate Loans in a principal amount equal to $3,000,000 or
any whole multiple of $1,000,000 in excess thereof into one or more LIBOR Rate
Loans and (b) upon the expiration of any Interest Period, (i) convert all or
any part of its outstanding LIBOR Rate Loans in a principal amount equal to
$1,000,000 or a whole multiple of $500,000 in excess thereof into Base Rate
Loans or (ii) continue such LIBOR Rate Loans as LIBOR Rate Loans.  Whenever the
Borrower desires to convert or continue Loans as provided above, the Borrower
shall give the Administrative Agent irrevocable prior written notice in the
form attached as 

                                      22
<PAGE>   28

Exhibit E (a "Notice of Conversion/ Continuation") not later than 11:00 a.m.
(Charlotte time) three (3) Business Days before the day on which a proposed
conversion or continuation of such Loan is to be effective specifying (A) the
Loans to be converted or continued, and, in the case of any LIBOR Rate Loan to
be converted or continued, the last day of the Interest Period therefor, (B) the
effective date of such conversion or continuation (which shall be a Business
Day), (C) the principal amount of such Loans to be converted or continued, and
(D) the Interest Period to be applicable to such converted or continued LIBOR
Rate Loan.  The Administrative Agent shall promptly notify the Lenders of such
Notice of Conversion/Continuation.

      SECTION 4.3       Fees.

      (a)     Commitment Fee. The Borrower shall pay to the Administrative
Agent, for the account of the Lenders, a non-refundable commitment fee on the
average monthly un-utilized portion of the Aggregate Commitment, such
commitment fee equal to (i) 0.50% per annum if the average monthly utilized
portion of the Aggregate Commitment equals or exceeds fifty percent (50%) of
the Credit Facility or (ii) 0.75% per annum if the average monthly utilized
portion of the Aggregate Commitment is less than fifty percent (50%) of the
Credit Facility.  The commitment fee shall be payable in arrears on the last
Business Day of each calendar quarter during the term of this Agreement
commencing March 31, 1999, and on the Termination Date.  Such commitment fee
shall be distributed by the Administrative Agent to the Lenders pro rata in
accordance with the Lenders' respective Commitment Percentages.

      (b)     Administrative Agent's and Other Fees.  In order to compensate
the Administrative Agent for structuring and syndicating the Loans and for its
obligations hereunder, the Borrower agrees to pay to the Administrative Agent,
for its account, the fees set forth in the separate fee letter agreement
executed by the Borrower, the Arranger and the Administrative Agent and dated
January 9, 1999.

      SECTION 4.4       Manner of Payment.  Each payment by the Borrower on
account of the principal of or interest on the Loans or of any fee, commission
or other amounts (including the Reimbursement Obligation) payable to the
Lenders under this Agreement or any Note shall be made not later than 1:00 p.m.
(Charlotte time) on the date specified for payment under this Agreement to the
Administrative Agent at the Administrative Agent's Office for the account of
the Lenders (other than as set forth below) pro rata in accordance with their
respective Commitment Percentages (except as specified below), in Dollars, in
immediately available funds and shall be made without any set-off, counterclaim
or deduction whatsoever.  Any payment received after such time but before 2:00
p.m. (Charlotte time) on such day shall be deemed a payment on such date for
the purposes of Section 11.1, but for all other purposes shall be deemed to
have been made on the next succeeding Business Day.  Any payment received after
2:00 p.m. (Charlotte time) shall be deemed to have been made on the next
succeeding Business Day for all purposes.  Upon receipt by the Administrative
Agent of each such payment, the Administrative Agent shall distribute to each
Lender at its address for notices set forth herein its pro rata share of such
payment in accordance with such Lender's Commitment Percentage (except as
specified below) and shall wire advice of the amount of such credit to each
Lender.  Each payment to the Administrative Agent of the Issuing Lender's fees
or L/C Participants' commissions shall be 


                                      23
<PAGE>   29

made in like manner, but for the account of the Issuing Lender or the L/C
Participants, as the case may be. Each payment to the Administrative Agent of
Administrative Agent's fees or expenses shall be made for the account of the
Administrative Agent and any amount payable to any Lender under Sections 4.8,
4.9, 4.10, 4.11 or 13.2 shall be paid to the Administrative Agent for the
account of the applicable Lender.  Subject to Section 4.1(b)(ii) if any payment
under this Agreement or any Note shall be specified to be made upon a day which
is not a Business Day, it shall be made on the next succeeding day which is a
Business Day and such extension of time shall in such case be included in
computing any interest if payable along with such payment.

      SECTION 4.5       Crediting of Payments and Proceeds.  In the event that
the Borrower shall fail to pay any of the Obligations when due and the
Obligations have been accelerated pursuant to Section 11.2, all payments
received by the Lenders upon the Notes and the other Obligations and all net
proceeds from the enforcement of the Obligations shall be applied first to all
expenses then due and payable by the Borrower hereunder, then to all indemnity
obligations then due and payable by the Borrower hereunder, then to all
Administrative Agent's and Issuing Lender's fees then due and payable, then to
all commitment and other fees and commissions then due and payable, then to
accrued and unpaid interest on the Notes, the Reimbursement Obligations and any
termination payments due in respect of a Hedging Agreement with any Lender
(which Hedging Agreement is permitted or required hereunder) (pro rata in
accordance with all such amounts due), then to the principal amount of the
Notes and Reimbursement Obligations (pro rata in accordance with all such
amounts due) and then to the cash collateral account described in Section
11.2(b) hereof to the extent of any L/C Obligations then outstanding, in that
order.

      SECTION 4.6       Adjustments.  If any Lender (a "Benefitted Lender")
shall at any time receive any payment of all or part of the Obligations owing
to it, or interest thereon, or if any Lender shall at any time receive any
collateral in respect to the Obligations owing to it (whether voluntarily or
involuntarily, by set-off or otherwise) in a greater proportion than any such
payment to and collateral received by any other Lender, if any, in respect of
the Obligations owing to such other Lender, or interest thereon, such Benefitted
Lender shall purchase for cash from the other Lenders such portion of each such
other Lender's Extensions of Credit, or shall provide such other Lenders with
the benefits of any such collateral, or the proceeds thereof, as shall be
necessary to cause such Benefitted Lender to share the excess payment or
benefits of such collateral or proceeds ratably with each of the Lenders;
provided, that if all or any portion of such excess payment or benefits is
thereafter recovered from such Benefitted Lender, such purchase shall be
rescinded, and the purchase price and benefits returned to the extent of such
recovery, but without interest.  The Borrower agrees that each Lender so
purchasing a portion of another Lender's Extensions of Credit may exercise all
rights of payment (including, without limitation, rights of set-off) with
respect to such portion as fully as if such Lender were the direct holder of
such portion.

      SECTION 4.7       Nature of Obligations of Lenders Regarding Extensions
of Credit; Assumption by the Administrative Agent.  The obligations of the
Lenders under this Agreement to make the Loans and issue or participate in
Letters of Credit are several and are not joint or joint and several. Unless
the Administrative Agent shall have received notice from a Lender prior to a
proposed borrowing date that such Lender will not make available to the


                                      24
<PAGE>   30


Administrative Agent such Lender's ratable portion of the amount to be borrowed
on such date (which notice shall not release such Lender of its obligations
hereunder), the Administrative Agent may assume that such Lender has made such
portion available to the Administrative Agent on the proposed borrowing date in
accordance with Section 2.2(b) and the Administrative Agent may, in reliance
upon such assumption, make available to the Borrower on such date a
corresponding amount.  If such amount is made available to the Administrative
Agent on a date after such borrowing date, such Lender shall pay to the
Administrative Agent on demand an amount, until paid, equal to the product of
(a) the amount not made available by such Lender in accordance with the terms
hereof, times (b) the daily average Federal Funds Rate during such period as
determined by the Administrative Agent, times (c) a fraction the numerator of
which is the number of days that elapse from and including such borrowing date
to the date on which such amount not made available by such Lender in
accordance with the terms hereof shall have become immediately available to the
Administrative Agent and the denominator of which is 360.  A certificate of the
Administrative Agent with respect to any amounts owing under this Section shall
be conclusive, absent manifest error.  If such Lender's Commitment Percentage
of such borrowing is not made available to the Administrative Agent by such
Lender within three (3) Business Days of such borrowing date, the
Administrative Agent shall be entitled to recover such amount made available by
the Administrative Agent with interest thereon at the rate per annum applicable
to Base Rate Loans hereunder, on demand, from the Borrower.  The failure of any
Lender to make available its Commitment Percentage of any Loan requested by the
Borrower shall not relieve it or any other Lender of its obligation, if any,
hereunder to make its Commitment Percentage of such Loan available on the
borrowing date, but no Lender shall be responsible for the failure of any other
Lender to make its Commitment Percentage of such Loan available on the
borrowing date.

      SECTION 4.8       Changed Circumstances.

      (a)     Circumstances Affecting LIBOR Rate Availability.  If with respect
to any Interest Period the Administrative Agent or any Lender (after
consultation with Administrative Agent) shall determine that, by reason of
circumstances affecting the foreign exchange and interbank markets generally,
deposits in eurodollars, in the applicable amounts are not being quoted via
Telerate Page 3750 or offered to the Administrative Agent or such Lender for
such Interest Period, then the Administrative Agent shall forthwith give notice
thereof to the Borrower.  Thereafter, until the Administrative Agent notifies
the Borrower that such circumstances no longer exist (which notification shall
be given promptly, but in any event within thirty (30) days after the
Administrative Agent obtains actual knowledge that such circumstances no longer
exist), the obligation of the Lenders to make LIBOR Rate Loans and the right of
the Borrower to convert any Loan to or continue any Loan as a LIBOR Rate Loan
shall be suspended, and the Borrower shall repay in full (or cause to be repaid
in full) the then outstanding principal amount of each such LIBOR Rate Loan
together with accrued interest thereon, on the last day of the then current
Interest Period applicable to such LIBOR Rate Loan or convert the then
outstanding principal amount of each such LIBOR Rate Loan to a Base Rate Loan
as of the last day of such Interest Period.

      (b)     Laws Affecting LIBOR Rate Availability.  If, after the date
hereof, the introduction of, or any change in, any Applicable Law or any change
in the interpretation or 


                                      25
<PAGE>   31

administration thereof by any Governmental Authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance
by any Lender (or any of their respective Lending Offices) with any request or
directive (whether or not having the force of law) of any such Authority,
central bank or comparable agency, shall make it unlawful or impossible for any
of the Lenders (or any of their respective Lending Offices) to honor its
obligations hereunder to make or maintain any LIBOR Rate Loan, such Lender shall
promptly give notice thereof to the Administrative Agent and the Administrative
Agent shall promptly give notice to the Borrower and the other Lenders. 
Thereafter, until the Administrative Agent notifies the Borrower that such
circumstances no longer exist (which notification shall be given promptly, but
in any event within thirty (30) days after the Administrative Agent obtains
actual knowledge that such circumstances no longer exist), (i) the obligations
of the Lenders to make LIBOR Rate Loans and the right of the Borrower to convert
any Loan or continue any Loan as a LIBOR Rate Loan shall be suspended and
thereafter the Borrower may select only Base Rate Loans hereunder, and (ii) if
any of the Lenders may not lawfully continue to maintain a LIBOR Rate Loan to
the end of the then current Interest Period applicable thereto as a LIBOR Rate
Loan, the applicable LIBOR Rate Loan shall immediately be converted to a Base
Rate Loan for the remainder of such Interest Period.

      (c)     Increased Costs.  If, after the date hereof, the introduction of,
or any change in, any Applicable Law, or in the interpretation or
administration thereof by any Governmental Authority, central bank or
comparable agency charged with the interpretation or administration thereof, or
compliance by any of the Lenders (or any of their respective Lending Offices)
with any request or directive (whether or not having the force of law) of such
Authority, central bank or comparable agency:

               (i)      shall subject any of the Lenders (or any of their
respective Lending Offices) to any tax, duty or other charge with respect to
any Note, Letter of Credit or Application or shall change the basis of taxation
of payments to any of the Lenders (or any of their respective Lending Offices)
of the principal of or interest on any Note, Letter of Credit or Application or
any other amounts due under this Agreement in respect thereof (except for
changes in the rate of tax on the overall net income of any of the Lenders or
any of their respective Lending Offices imposed by the jurisdiction in which
such Lender is organized or is or should be qualified to do business or such
Lending Office is located); or

               (ii)     shall impose, modify or deem applicable any reserve
(including, without limitation, any imposed by the Board of Governors of the
Federal Reserve System), special deposit, insurance or capital or similar
requirement against assets of, deposits with or for the account of, or credit
extended by any of the Lenders (or any of their respective Lending Offices) or
shall impose on any of the Lenders (or any of their respective Lending Offices)
or the foreign exchange and interbank markets any other condition affecting any
Note;

and the result of any of the foregoing is to increase the costs to any of the
Lenders of maintaining any LIBOR Rate Loan or issuing or participating in
Letters of Credit or to reduce the yield or amount of any sum received or
receivable by any of the Lenders under this Agreement or under the Notes in
respect of a LIBOR Rate Loan or Letter of Credit or Application, then such
Lender shall promptly notify the Administrative Agent, and the Administrative
Agent shall promptly 


                                      26
<PAGE>   32

notify the Borrower of such fact and demand compensation therefor and, within
fifteen (15) days after such notice by the Administrative Agent, the Borrower
shall pay to such Lender such additional amount or amounts as will compensate
such Lender or Lenders for such increased cost or reduction. The Administrative
Agent will promptly notify the Borrower of any event of which it has knowledge
which will entitle such Lender to compensation pursuant to this Section 4.8(c);
provided, that the Administrative Agent shall incur no liability whatsoever to
the Lenders or the Borrower in the event it fails to do so.  The amount of such
compensation shall be determined, in the applicable Lender's sole discretion,
based upon the assumption that such Lender funded its Commitment Percentage of
the LIBOR Rate Loans in the London interbank market and using any reasonable
attribution or averaging methods which such Lender deems appropriate and
practical.  A certificate of such Lender setting forth the basis for determining
such amount or amounts necessary to compensate such Lender shall be forwarded to
the Borrower through the Administrative Agent and shall be conclusively presumed
to be correct save for manifest error.

      SECTION 4.9       Indemnity.  The Borrower hereby indemnifies
each of the Lenders against any loss or expense which may arise or be
attributable to each Lender's obtaining, liquidating or employing deposits or
other funds acquired to effect, fund or maintain any Loan (a) as a consequence
of any failure by the Borrower to make any payment when due of any amount due
hereunder in connection with a LIBOR Rate Loan, (b) due to any failure of the
Borrower to borrow on a date specified therefor in a Notice of Borrowing or
Notice of Continuation/Conversion or (c) due to any payment, prepayment or
conversion of any LIBOR Rate Loan on a date other than the last day of the
Interest Period therefor.  The amount of such loss or expense shall be
determined, in the applicable Lender's sole discretion, based upon the
assumption that such Lender funded its Commitment Percentage of the LIBOR Rate
Loans in the London interbank market and using any reasonable attribution or
averaging methods which such Lender deems appropriate and practical.  A
certificate of such Lender setting forth the basis for determining such amount
or amounts necessary to compensate such Lender shall be forwarded to the
Borrower through the Administrative Agent and shall be conclusively presumed to
be correct save for manifest error.

      SECTION 4.10      Capital Requirements.  If either (a) the introduction
of, or any change in, or in the interpretation of, any Applicable Law or (b)
compliance with any guideline or request from any central bank or comparable
agency or other Governmental Authority (whether or not having the force of
law), has or would have the effect of reducing the rate of return on the
capital of, or has affected or would affect the amount of capital required to
be maintained by, any Lender or any corporation controlling such Lender as a
consequence of, or with reference to the Commitments and other commitments of
this type, below the rate which the Lender or such other corporation could have
achieved but for such introduction, change or compliance, then within five (5)
Business Days after written demand by any such Lender, the Borrower shall pay
to such Lender from time to time as specified by such Lender additional amounts
sufficient to compensate such Lender or other corporation for such reduction.
A certificate as to such amounts submitted to the Borrower and the
Administrative Agent by such Lender, shall, in the absence of manifest error,
be presumed to be correct and binding for all purposes.



                                      27
<PAGE>   33

      SECTION 4.11      Taxes.

      (a)      Payments Free and Clear.  Any and all payments by the Borrower
hereunder or under the Notes or the Letters of Credit shall be made free and
clear of and without deduction for any and all present or future taxes, levies,
imposts, deductions, charges or withholding, and all liabilities with respect
thereto excluding, (i) in the case of each Lender and the Administrative Agent,
income and franchise taxes imposed by the jurisdiction under the laws of which
such Lender or the Administrative Agent (as the case may be) is organized or is
or should be qualified to do business or any political subdivision thereof and
(ii) in the case of each Lender, income and franchise taxes imposed by the
jurisdiction of such Lender's Lending Office or any political subdivision
thereof (all such non-excluded taxes, levies, imposts, deductions, charges,

amount such party would have received had no such deductions been made, (B) the

Administrative Agent for the full amount of Taxes and Other Taxes (including,
without limitation, any Taxes and Other Taxes imposed by any jurisdiction on
amounts payable under this Section 4.11) paid by such Lender or the
Administrative Agent (as the case may be) and any liability (including

each case that such Lender is entitled to a complete exemption from withholding
or deduction for or on account of any United States federal income taxes, and
(ii) an Internal Revenue Service Form W-8 or W-9 or successor applicable form,
as the case may be, to establish an exemption from United States backup
withholding taxes.  Each such Lender further agrees to deliver to the Borrower,
with a copy to the Administrative Agent, a Form 1001 or 4224 and Form W-8 or
W-9, or successor applicable forms or manner of certification, as the case may
be, on or before the date that any such form expires or becomes obsolete or

previously delivered by it to the Borrower, certifying in the case of a Form

Agreement without deduction or withholding of any United States federal income
taxes (unless in any such case an event (including without limitation any change
in treaty, law or regulation) has occurred prior to the date on which any such
delivery would otherwise be required which renders such forms inapplicable or

the Borrower and the Administrative Agent that it is not entitled to receive

designate another lending office as its Lending Office for any Loans affected
by such event with the intent of avoiding the consequence of the event giving
rise to the operation of any such Section; provided, that such designation is
made on such terms that such Lender and its Lending Office suffer no economic,
legal or regulatory disadvantage as a consequence thereof.

Administrative Agent and Lenders to enter into this Agreement and to induce the
Lenders to make Extensions of Credit, the Borrower hereby represents and
warrants to the Administrative Agent and Lenders both before and after giving
effect to the transactions contemplated hereunder that:

      (a)     Organization; Power; Qualification.  Each of the Borrower and its
Subsidiaries is duly organized, validly existing and in good standing under the
laws of the jurisdiction of its incorporation or formation, has the power and
authority to own its properties and to carry on its business as now being
conducted (and as hereafter conducted at the time of any supplement to Schedule
6.1(a) required pursuant to Section 8.12) and is duly qualified and authorized
to do business in each jurisdiction in which the character of its properties or
the nature of its business requires such qualification and authorization,
except where the failure to be so qualified could not reasonably be expected to
have a Material Adverse Effect.  The jurisdictions in which the Borrower and
its Subsidiaries are organized and qualified to do business as of the Closing
Date or any date on which Schedule 6.1(a) is supplemented in accordance with
Section 8.12, as applicable, are described on Schedule 6.1(a).

      (b)     Ownership.  Each Subsidiary of the Borrower as of the Closing
Date or any date on which Schedule 6.1(b) is supplemented in accordance with
Section 8.12, as applicable, is listed on Schedule 6.1(b).  As of the Closing
Date, the Borrower has no Subsidiaries.  As of the Closing Date, or any date on
which Schedule 6.1(b) is supplemented in accordance with Section 8.12, as
applicable, the capitalization of the Borrower and its Subsidiaries consists of
the number of shares, authorized, issued and outstanding, of such classes and
series, with or without par value, described on Schedule 6.1(b).  All

and the number of shares owned by each as of the Closing Date or any date on
which Schedule 6.1(b) is supplemented in accordance with Section 8.12, as
applicable, are described on Schedule 6.1(b).  As of the Closing Date or any
date on which Schedule 6.1(b) is supplemented in accordance with Section 8.12,
there are no outstanding stock purchase warrants, subscriptions, options,
securities, instruments or other rights of any type or nature whatsoever, which
are convertible into, exchangeable for or otherwise provide for or permit the
issuance of capital stock of the Borrower or its Subsidiaries, except as
described on Schedule 6.1(b).

      (c)     Authorization of Agreement, Loan Documents and Borrowing. Each of
the Borrower and its Subsidiaries has the right, power and authority and has
taken all necessary corporate and other action to authorize the execution,
delivery and performance of this Agreement and each of the other Loan Documents
to which it is a party in accordance with their respective terms.  This
Agreement and each of the other Loan Documents have been duly executed and
delivered by the duly authorized officers of the Borrower and each of its
Subsidiaries party thereto, and each such document constitutes the legal, valid
and binding obligation of the Borrower or its Subsidiary party thereto,
enforceable in accordance with its terms, except as such enforcement may be
limited by bankruptcy, insolvency, reorganization, 

                                     35

moratorium or similar state or federal debtor relief laws from time to time in
effect which affect the enforcement of creditors' rights in general and the
availability of equitable remedies.

      (d)     Compliance of Agreement, Loan Documents and Borrowing with Laws,
Etc.  The execution, delivery and performance by the Borrower and its
Subsidiaries of the Loan Documents to which each such Person is a party, in
accordance with their respective terms, the borrowings hereunder and the
transactions contemplated hereby do not and will not, by the passage of time,
the giving of notice or otherwise, (i) require any Governmental Approval or
violate any Applicable Law relating to the Borrower or any of its Subsidiaries,
(ii) conflict with, result in a breach of or constitute a default under the
articles of incorporation, bylaws or other organizational documents of the
Borrower or any of its Subsidiaries or any Material Contract to which such
Person is a party or by which any of its properties may be bound or any
Governmental Approval relating to such Person, or (iii) result in or require
the creation or imposition of any Lien upon or with respect to any property now
owned or hereafter acquired by such Person other than Liens arising under the
Loan Documents.

      (e)     Compliance with Law; Governmental Approvals.  Each of the
Borrower and its Subsidiaries (i) has all material Governmental Approvals
including any necessary Communications Licenses required by any Applicable Law
for it to conduct its business, each of which is in full force and effect, is
final and not subject to review on appeal and is not the subject of any pending
or, to the best of its knowledge, threatened attack by direct or collateral
proceeding, and (ii) is in material compliance with each material Governmental
Approval applicable to it and in material compliance with all other material
Applicable Laws relating to it or any of its respective properties.

      (f)     Tax Returns and Payments.  Each of the Borrower and its Subsidies
has duly filed or caused to be filed all federal, state, local and other tax
returns required by Applicable Law to be filed, and has paid, or made adequate
provision for the payment of, all federal, state, local and other taxes,
assessments and governmental charges or levies upon it and its property,
income, profits and assets which are due and payable, except where the payment
of such tax is being disputed in good faith and adequate reserves have been
established in accordance with GAAP.  No Governmental Authority has asserted
any Lien or other claim against the Borrower or Subsidiary thereof with respect
to material unpaid taxes which has not been discharged or resolved or is not
being contested in good faith and for which adequate reserves have been
established in accordance with GAAP.  The charges, accruals and reserves on the
books of the Borrower and any of its Subsidiaries in respect of federal, state,
local and other taxes for all Fiscal Years and portions thereof since the
organization of the Borrower and any of its Subsidiaries are in the judgment of
the Borrower adequate, and the Borrower does not anticipate any additional
material taxes or assessments for any of such years.

      (g)     Intellectual Property Matters.  Each of the Borrower and its
Subsidiaries owns or possesses rights to use all material franchises, licenses,
copyrights, copyright applications, patents, patent rights or licenses, patent
applications, trademarks, trademark rights, trade names, trade name rights,
copyrights and rights with respect to the foregoing which are required to
conduct its business.  No event has occurred which permits, or after notice or
lapse of time or both would permit, the revocation or termination of any such
rights (except where such 

                                     36
<PAGE>   42

revocation or termination could not reasonably be expected to have a Material
Adverse Effect), and neither the Borrower nor any Subsidiary thereof is liable
to any Person for infringement under Applicable Law with respect to any such
rights as a result of its business operations.

      (h)     Environmental Matters.

               (i)         The properties owned, leased or operated by
the Borrower anubsidiaries do not contain, and to the Borrower's knowledge have
not previously contained, any Hazardous Materials in amounts or concentrations
which (A) constitute or constituted a violation of applicable Environmental

except where such violation or liability could not reasonably be expected to
result in a Material Adverse Effect;

               (ii)        The Borrower, each Subsidiary and such properties
and all operations conducted in connection therewith are in compliance, and
have been in compliance, with all applicable Environmental Laws, and there is

fair saleable value thereof, except where any such event could not reasonably
be expected to result in a Material Adverse Effect;

               (iii)       Neither the Borrower nor any Subsidiary
thereof has received any notice of violation, alleged violation,
non-compliance, liability or potential liability regarding environmental
matters, Hazardous Materials, or compliance with Environmental Laws, nor does
the Borrower have knowledge or reason to believe that any such notice will be
received or is being threatened, except where such notice could not reasonably
be expected to result in a Material Adverse Effect;

               (iv)        To the Borrower's knowledge, Hazardous Materials
have not been transported or disposed of to or from the properties owned,
leased or operated by the Borrower and its Subsidiaries in violation of, or in
a manner or to a location which could give rise to liability under,
Environmental Laws, nor since the date of acquisition of such property by the
Borrower or its Subsidiaries have any Hazardous Materials been generated,
treated, stored or disposed of at, on or under any of such properties in
violation of, or in a manner that could give rise to liability under, any
applicable Environmental Laws, except where the failure to so comply or the
existence of such contamination could not reasonably be expected to result in a
Material Adverse Effect;

               (v)         No judicial proceedings or governmental or
administrative action is pending, or, to the knowledge of the Borrower,
threatened, under any Environmental Law to which the Borrower or any Subsidiary

consent decrees or other decrees, consent orders, administrative orders or
other orders, or other administrative or judicial requirements outstanding

<PAGE>   43


               (vi)        Since the date of the acquisition of any property,
there has been no release or to the Borrower's knowledge, threat of release of
Hazardous Materials at or from properties owned, leased or operated by the
Borrower or any Subsidiary, now or in the past, in violation of or in amounts
or in a manner that could give rise to liability under Environmental Laws,
except where such release could not reasonably be expected to result in a
Material Adverse Effect.

      (i)   ERISA.

               (i)         As of the Closing Date, neither the Borrower nor any
ERISA Affiliate maintains or contributes to, or has any obligation under, any
Employee Benefit Plans other than those identified on Schedule 6.1(i);

               (ii)        The Borrower and each ERISA Affiliate is in material
compliance with all applicable provisions of ERISA and the regulations and
published interpretations thereunder with respect to all Employee Benefit Plans
except for any required amendments for which the remedial amendment period as
defined in Section 401(b) of the Code has not yet expired.  Each Employee
Benefit Plan that is intended to be qualified under Section 401(a) of the Code
(A) has been determined by the Internal Revenue Service to be so qualified, and
each trust related to such plan has been determined to be exempt under Section
501(a) of the Code or (B) is within the remedial amendment period as defined in
Section 401(b) of the Code as of the initial adoption of such Employee Benefit
Plan.  No liability has been incurred by the Borrower or any ERISA Affiliate
which remains unsatisfied for any taxes or penalties with respect to any
Employee Benefit Plan or any Multiemployer Plan;

               (iii)       No Pension Plan has been terminated, nor has
any accumulated funding deficiency (as defined in Section 412 of the Code) been
incurred (without regard to any waiver granted under Section 412 of the Code),
nor has any funding waiver from the Internal Revenue Service been received or
requested with respect to any Pension Plan, nor has the Borrower or any ERISA
Affiliate failed to make any contributions or to pay any amounts due and owing
as required by Section 412 of the Code, Section 302 of ERISA or the terms of
any Pension Plan prior to the due dates of such contributions under Section 412
of the Code or Section 302 of ERISA, nor has there been any event requiring any
disclosure under Section 4041(c)(3)(C) or 4063(a) of ERISA with respect to any
Pension Plan;

               (iv)        Neither the Borrower nor any ERISA Affiliate has:
(A) engaged in a nonexempt prohibited transaction described in Section 406 of
the ERISA or Section 4975 of the Code, (B) incurred any liability to the PBGC
which remains outstanding other than the payment of premiums and there are no
premium payments which are due and unpaid, (C) failed to make a required
contribution or payment to a Multiemployer Plan, or (D) failed to make a

               (v)         No Termination Event has occurred or is reasonably

                                     38
<PAGE>   44


               (vi)        No material proceeding, claim, lawsuit and/or
investigation is existing or, to the best knowledge of the Borrower after due
inquiry, threatened concerning or involving any (A) employee welfare benefit
plan (as defined in Section 3(1) of ERISA) currently maintained or contributed
to by the Borrower or any ERISA Affiliate, (B) Pension Plan or (C)
Multiemployer Plan.

      (j)     Margin Stock.  Neither the Borrower nor any Subsidiary thereof is
engaged principally or as one of its activities in the business of extending
credit for the purpose of "purchasing" or "carrying" any "margin stock" (as
each such term is defined or used in Regulation U of the Board of Governors of
the Federal Reserve System).  No part of the proceeds of any of the Loans or
Letters of Credit will be used for purchasing or carrying margin stock or for
any purpose which violates, or which would be inconsistent with, the provisions
of Regulation T, U or X of such Board of Governors.

      (k)     Government Regulation.  Neither the Borrower nor any Subsidiary
thereof is an "investment company" or a company "controlled" by an "investment
company" (as each such term is defined or used in the Investment Company Act of
1940, as amended) and neither the Borrower nor any Subsidiary thereof is, or
after giving effect to any Extension of Credit will be, subject to regulation
under the Public Utility Holding Company Act of 1935 or the Interstate Commerce
Act, each as amended, or any other Applicable Law which limits its ability to
incur or consummate the transactions contemplated hereby.

      (l)     Material Contracts.  Schedule 6.1(l) sets forth a complete and
accurate list of all Material Contracts of the Borrower and its Subsidiaries
including all network services agreements in effect as of the Closing Date not
listed on any other Schedule hereto; other than as set forth in Schedule
6.1(l), each such Material Contract is, and after giving effect to the
consummation of the transactions contemplated by the Loan Documents will be, in
full force and effect in accordance with the terms thereof.  The Borrower has
delivered to the Administrative Agent a true and complete copy of each Material
Contract required to be listed on Schedule 6.1(l) or any other Schedule hereto.

      (m)     Employee Relations. Each of the Borrower and its Subsidiaries has
a stable work force in place and is not, as of the Closing Date, party to any
collective bargaining agreement nor has any labor union been recognized as the
representative of its employees except as set forth on Schedule 6.1(m). The
Borrower knows of no pending, threatened or contemplated strikes, work stoppage
or other collective labor disputes involving its employees or those of its
Subsidiaries.

      (n)     Burdensome Provisions.  Neither the Borrower nor any Subsidiary
thereof is a party to any indenture, agreement, lease or other instrument, or
subject to any corporate or partnership restriction, Governmental Approval or
Applicable Law which is so unusual or burdensome as in the foreseeable future
could be reasonably expected to have a Material Adverse Effect.  The Borrower
does not presently anticipate that future expenditures needed to meet the
provisions of any statutes, orders, rules or regulations of a Governmental
Authority will be so burdensome as to have a Material Adverse Effect.


                                     39
<PAGE>   45


      (o)     Financial Statements.  The financial statements required to be
provided to the Administrative Agent pursuant to Section 5.2(e)(i)(A) are
complete and correct and fairly present the assets, liabilities and financial
position of the Borrower and its Subsidiaries as at such dates, and the results
of the operations and changes of financial position for the periods then ended
(except in the case of unaudited statement to changes resulting from normal
year-end adjustments and items that would be disclosed in footnotes to the
audited statements).  All such financial statements, including the related
schedules and notes thereto, have been prepared in accordance with GAAP.  The
Borrower and its Subsidiaries have no Debt, material obligation or other
unusual material forward or long-term commitment which is not fairly reflected
in the foregoing financial statements or in the notes thereto.

      (p)     No Material Adverse Change.  Since December 31, 1997, there has
been no material adverse change in the properties, business, operations,
prospects, or condition (financial or otherwise) of the Borrower and its
Subsidiaries and no event has occurred or condition arisen that could
reasonably be expected to have a Material Adverse Effect.

      (q)     Solvency.  As of the Closing Date and after giving effect to each
Extension of Credit made hereunder, the Borrower and its Subsidiaries, taken as
a whole, will be Solvent.

      (r)     Titles to Properties.  Each of the Borrower and its Subsidiaries
has such title to the real property owned by it as is necessary or desirable to
the conduct of its business and valid and legal title to all of its personal
property and assets, including, but not limited to, those reflected on the
balance sheets of the Borrower and its Subsidiaries delivered pursuant to
Section 6.1(o), except those which have been disposed of by the Borrower or its
Subsidiaries subsequent to such date which dispositions have been in the
ordinary course of business or as otherwise expressly permitted hereunder.

      (s)     Liens.  None of the properties and assets of the Borrower or any
Subsidiary thereof is subject to any Lien, except Liens permitted pursuant to
Section 10.3.  No financing statement under the Uniform Commercial Code of any
state which names the Borrower or any Subsidiary thereof or any of their
respective trade names or divisions as debtor and which has not been
terminated, has been filed in any state or other jurisdiction and neither the
Borrower nor any Subsidiary thereof has signed any such financing statement or
any security agreement authorizing any secured party thereunder to file any
such financing statement, except to perfect those Liens permitted by Section
10.3 hereof.

      (t)     Debt and Guaranty Obligations.  Schedule 6.1(t) is a complete and
correct listing of all Debt and Guaranty Obligations of the Borrower and its
Subsidiaries as of the Closing Date in excess of $500,000.  The Borrower and
its Subsidiaries have performed and are in compliance with all of the material
terms of such Debt and Guaranty Obligations and all instruments and agreements
relating thereto, and no default or event of default, or event or condition
which with notice or lapse of time or both would constitute such a default or
event of default on the part of the Borrower or its Subsidiaries exists with
respect to any such Debt or Guaranty Obligation.

      (u)     Litigation.  Except for matters existing on the Closing Date and
set forth on Schedule 6.1(u), there are no actions, suits or proceedings
pending nor, to the knowledge of the 


                                     40
<PAGE>   46


Borrower, threatened against or in any other way relating adversely to or
affecting the Borrower or any Subsidiary thereof or any of their respective
properties in any court or before any arbitrator of any kind or before or by
any Governmental Authority which is reasonably likely to have a Material
Adverse Effect.

      (v)     Absence of Defaults.  No event has occurred or is continuing (i)
which constitutes a Default or an Event of Default, or (ii) which constitutes,
or which with the passage of time or giving of notice or both would constitute,
a default or event of default by the Borrower or any Subsidiary thereof under
any Material Contract or judgment, decree or order to which the Borrower or its
Subsidiaries is a party or by which the Borrower or its Subsidiaries or any of
their respective properties may be bound or which would require the Borrower or
its Subsidiaries to make any payment thereunder prior to the scheduled maturity
date therefor which, with respect to the matters set forth in clause (ii) could
reasonably be expected to result in a Material Adverse Effect.

      (w)     Telecommunications Matters

               (i)         Communications Licenses.  Schedule 6.1(w)(i) hereto
sets forth, as of the Closing Date and each subsequent date required pursuant
to Section 8.12, a true and complete list of all Communications Licenses (and
the expiration dates thereof) of the Borrower and its Subsidiaries pertaining
to the provision of internet services, and, if applicable, the jurisdiction
served thereby.

               (ii)        Condition of Systems.  All of the properties,
equipment and systems of the Borrower and its Subsidiaries are in good repair,
working order and condition, ordinary wear and tear excepted.

               (iii)       Subscribers.  As of the Closing Date, (A) the number
of dial-up, Web-hosting and dedicated access subscribers that are being
acquired pursuant to the Netcom Acquisition is not less than 395,000 and the
average revenue per such subscriber for the fiscal quarter ending December 31,
1998 was not less than $28.00; and (B) the number of dial-up, Web-hosting and
dedicated access subscribers on a Consolidated basis, including the acquired
Netcom subscribers, for the Borrower is not less than 1,100,000.

      (x)     Accuracy and Completeness of Information.  All written
information, reports and other papers and data produced by or on behalf of the
Borrower or any Subsidiary thereof and furnished to the Lenders were, at the
time the same were so furnished, complete and correct in all material respects
to the extent necessary to give the recipient a true and accurate knowledge of
the subject matter.  No document furnished or written statement made to the
Administrative Agent or the Lenders by the Borrower or any Subsidiary thereof
in connection with the negotiation, preparation or execution of this Agreement
or any of the Loan Documents contains or will contain any untrue statement of a
material fact to the creditworthiness of the Borrower or its Subsidiaries or
omits or will omit to state a material fact necessary in order to make the
statements contained therein not misleading.  The Borrower is not aware of any
facts which it has not disclosed in writing to the Administrative Agent having
a Material Adverse Effect, or 

                                     41
<PAGE>   47

insofar as the Borrower can now foresee, could reasonably be expected to have a
Material Adverse Effect.

      SECTION 6.2       Survival of Representations and Warranties, Etc.  All
representations and warranties set forth in this Article VI and all
representations and warranties contained in any certificate, or any of the Loan
Documents (including but not limited to any such representation or warranty
made in or in connection with any amendment thereto) shall constitute
representations and warranties made under this Agreement.  All representations
and warranties made under this Agreement shall be made or deemed to be made at
and as of the Closing Date, shall survive the Closing Date and shall not be
waived by the execution and delivery of this Agreement, any investigation made
by or on behalf of the Lenders or any borrowing hereunder.

Borrower or Subsidiary party thereto or any such Person shall so state in
writing, or this Agreement or any other Loan Document shall for any reason

interest in, any of the collateral purported to be covered thereby, in each
case other than in accordance with the express terms hereof or thereof.

      (m)     Termination Event.  The occurrence of any of the following

      SECTION 11.2      Remedies.  Upon the occurrence of an Event of
Default, with the consent of the Required Lenders, the Administrative Agent
may, or upon the request of the Required Lenders, the Administrative Agent
shall, by notice to the Borrower:

      (a)     Acceleration; Termination of Facilities.  Declare the principal
of and interest on the Loans, the Notes and the Reimbursement Obligations at
the time outstanding, and all other amounts owed to the Lenders and to the
Administrative Agent under this Agreement or any of the other Loan Documents
(other than any Hedging Agreement) (including, without limitation, all L/C
Obligations, whether or not the beneficiaries of the then outstanding Letters
of Credit shall have presented the documents required thereunder) and all other
Obligations (other than obligations owing under any Hedging Agreement), to be
forthwith due and payable, whereupon the same shall immediately become due and
payable without presentment, demand, protest or other notice of any kind, all
of which are expressly waived, anything in this Agreement or the other Loan
Documents to the contrary notwithstanding, and terminate the Credit Facility
and any right of the Borrower to request borrowings or Letters of Credit
thereunder; provided, that upon the occurrence of an Event of Default specified
in Section 11.1(j) or (k), the Credit Facility shall 


                                     57
<PAGE>   63

be automatically terminated and all Obligations (other than obligations owing
under any Hedging Agreement) shall automatically become due and payable.

      (b)     Letters of Credit.  With respect to all Letters of Credit with
respect to which presentment for honor shall not have occurred at the time of
an acceleration pursuant to the preceding paragraph, require the Borrower at
such time to deposit in a cash collateral account opened by the Administrative
Agent an amount equal to the aggregate then undrawn and unexpired amount of
such Letters of Credit.  Amounts held in such cash collateral account shall be
applied by the Administrative Agent to the payment of drafts drawn under such
Letters of Credit, and the unused portion thereof after all such Letters of
Credit shall have expired or been fully drawn upon, if any, shall be applied to
repay the other Obligations.  After all such Letters of Credit shall have
expired or been fully drawn upon, the Reimbursement Obligation shall have been
satisfied and all other Obligations shall have been paid in full, the balance,
if any, in such cash collateral account shall be returned to the Borrower.

      (c)     Rights of Collection.  Exercise on behalf of the Lenders all of
its other rights and remedies under this Agreement, the other Loan Documents
and Applicable Law, in order to satisfy all of the Borrower's Obligations.

      SECTION 11.3      Rights and Remedies Cumulative; Non-Waiver; etc.  The
enumeration of the rights and remedies of the Administrative Agent and the
Lenders set forth in this Agreement is not intended to be exhaustive and the
exercise by the Administrative Agent and the Lenders of any right or remedy
shall not preclude the exercise of any other rights or remedies, all of which
shall be cumulative, and shall be in addition to any other right or remedy
given hereunder or under the Loan Documents or that may now or hereafter exist
in law or in equity or by suit or otherwise.  No delay or failure to take
action on the part of the Administrative Agent or any Lender in exercising any
right, power or privilege shall operate as a waiver thereof, nor shall any
single or partial exercise of any such right, power or privilege preclude other
or further exercise thereof or the exercise of any other right, power or
privilege or shall be construed to be a waiver of any Event of Default.  No
course of dealing between the Borrower, the Administrative Agent and the
Lenders or their respective agents or employees shall be effective to change,
modify or discharge any provision of this Agreement or any of the other Loan
Documents or to constitute a waiver of any Event of Default.


                                  ARTICLE XII

                            THE ADMINISTRATIVE AGENT

      SECTION 12.1      Appointment. Each of the Lenders hereby irrevocably
designates and appoints First Union as Administrative Agent of such Lender
under this Agreement and the other Loan Documents for the term hereof and each
such Lender irrevocably authorizes First Union as Administrative Agent for such
Lender, to take such action on its behalf under the provisions of this
Agreement and the other Loan Documents and to exercise such powers and perform
such duties as are expressly delegated to the Administrative Agent by the terms
of this Agreement and such other Loan Documents, together with such other
powers as are reasonably 


                                     58
<PAGE>   64

incidental thereto. Notwithstanding any provision to the contrary elsewhere in
this Agreement or such other Loan Documents, the Administrative Agent shall not
have any duties or responsibilities, except those expressly set forth herein
and therein, or any fiduciary relationship with any Lender, and no implied
covenants, functions, responsibilities, duties, obligations or liabilities
shall be read into this Agreement or the other Loan Documents or otherwise
exist against the Administrative Agent. Any reference to the Administrative
Agent in this Article XII shall be deemed to refer to the Administrative Agent
solely in its capacity as Administrative Agent and not in its capacity as a
Lender.

      SECTION 12.2      Delegation of Duties. The Administrative Agent may
execute any of its respective duties under this Agreement and the other Loan
Documents by or through agents or attorneys-in-fact and shall be entitled to
advice of counsel concerning all matters pertaining to such duties. The
Administrative Agent shall not be responsible for the negligence or misconduct
of any agents or attorneys-in-fact selected by the Administrative Agent with
reasonable care.

      SECTION 12.3      Exculpatory Provisions. Neither the Administrative
Agent nor any of its officers, directors, employees, agents, attorneys-in-fact,
Subsidiaries or Affiliates shall be (a) liable for any action lawfully taken or
omitted to be taken by it or such Person under or in connection with this
Agreement or the other Loan Documents (except for actions occasioned solely by
its or such Person's own gross negligence or willful misconduct), or (b)
responsible in any manner to any of the Lenders for any recitals, statements,
representations or warranties made by the Borrower or any of its Subsidiaries
or any officer thereof contained in this Agreement or the other Loan Documents
or in any certificate, report, statement or other document referred to or
provided for in, or received by the Administrative Agent under or in connection
with, this Agreement or the other Loan Documents or for the value, validity,
effectiveness, genuineness, enforceability or sufficiency of this Agreement or
the other Loan Documents or for any failure of the Borrower or any of its
Subsidiaries to perform its obligations hereunder or thereunder. The
Administrative Agent shall not be under any obligation to any Lender to
ascertain or to inquire as to the observance or performance of any of the
agreements contained in, or conditions of, this Agreement, or to inspect the
properties, books or records of the Borrower or any of its Subsidiaries.

      SECTION 12.4      Reliance by the Administrative Agent. The
Administrative Agent shall be entitled to rely, and shall be fully protected in
relying, upon any note, writing, resolution, notice, consent, certificate,
affidavit, letter, cablegram, telegram, telecopy, telex or teletype message,
statement, order or other document or conversation believed by it to be genuine
and correct and to have been signed, sent or made by the proper Person or
Persons and upon advice and statements of legal counsel (including, without
limitation, counsel to the Borrower), independent accountants and other experts
selected by the Administrative Agent. The Administrative Agent may deem and
treat the payee of any Note as the owner thereof for all purposes unless such
Note shall have been transferred in accordance with Section 13.10 hereof. The
Administrative Agent shall be fully justified in failing or refusing to take
any action under this Agreement and the other Loan Documents unless it shall
first receive such advice or concurrence of the Required Lenders (or, when
expressly required hereby or by the relevant other Loan Document, all the
Lenders) as it deems appropriate or it shall first be indemnified to its
satisfaction by the Lenders against any and all liability and expense which may
be incurred by 


                                     59
<PAGE>   65

it by reason of taking or continuing to take any such action except for its own
gross negligence or willful misconduct. The Administrative Agent shall in all
cases be fully protected in acting, or in refraining from acting, under this
Agreement and the Notes in accordance with a request of the Required Lenders
(or, when expressly required hereby, all the Lenders), and such request and any
action taken or failure to act pursuant thereto shall be binding upon all the
Lenders and all future holders of the Notes.

      SECTION 12.5      Notice of Default. The Administrative Agent shall not
be deemed to have knowledge or notice of the occurrence of any Default or Event
of Default hereunder unless it has received notice from a Lender or the
Borrower referring to this Agreement, describing such Default or Event of
Default and stating that such notice is a "notice of default". In the event
that the Administrative Agent receives such a notice, it shall promptly give
notice thereof to the Lenders. The Administrative Agent shall take such action
with respect to such Default or Event of Default as shall be reasonably
directed by the Required Lenders; provided that unless and until the
Administrative Agent shall have received such directions, the Administrative
Agent may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Default or Event of Default as it
shall deem advisable in the best interests of the Lenders, except to the extent
that other provisions of this Agreement expressly require that any such action
be taken or not be taken only with the consent and authorization or the request
of the Lenders or Required Lenders, as applicable.

      SECTION 12.6      Non-Reliance on the Administrative Agent and Other
Lenders. Each Lender expressly acknowledges that neither the Administrative
Agent nor any of its respective officers, directors, employees, agents,
attorneys-in-fact, Subsidiaries or Affiliates has made any representations or
warranties to it and that no act by the Administrative Agent hereinafter taken,
including any review of the affairs of the Borrower or any of its Subsidiaries,
shall be deemed to constitute any representation or warranty by the
Administrative Agent to any Lender. Each Lender represents to the
Administrative Agent that it has, independently and without reliance upon the
Administrative Agent or any other Lender, and based on such documents and
information as it has deemed appropriate, made its own appraisal of and
investigation into the business, operations, property, financial and other
condition and creditworthiness of the Borrower and its Subsidiaries and made
its own decision to make its Loans and issue or participate in Letter of Credit
hereunder and enter into this Agreement. Each Lender also represents that it
will, independently and without reliance upon the Administrative Agent or any
other Lender, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit analysis, appraisals
and decisions in taking or not taking action under this Agreement and the other
Loan Documents, and to make such investigation as it deems necessary to inform
itself as to the business, operations, property, financial and other condition
and creditworthiness of the Borrower and its Subsidiaries. Except for notices,
reports and other documents expressly required to be furnished to the Lenders
by the Administrative Agent hereunder or by the other Loan Documents, the
Administrative Agent shall not have any duty or responsibility to provide any
Lender with any credit or other information concerning the business,
operations, property, financial and other condition or creditworthiness of the
Borrower or any of its Subsidiaries which may come into the possession of the
Administrative Agent or any of its respective officers, directors, employees,
agents, attorneys-in-fact, Subsidiaries or Affiliates.


                                     60
<PAGE>   66


      SECTION 12.7      Indemnification. The Lenders agree to indemnify the
Administrative Agent in its capacity as such and (to the extent not reimbursed
by the Borrower and without limiting the obligation of the Borrower to do so),
ratably according to the respective amounts of their Commitment Percentages,
from and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind whatsoever which may at any time (including, without limitation, at any
time following the payment of the Notes or any Reimbursement Obligation) be
imposed on, incurred by or asserted against the Administrative Agent in any way
relating to or arising out of this Agreement or the other Loan Documents, or
any documents contemplated by or referred to herein or therein or the
transactions contemplated hereby or thereby or any action taken or omitted by
the Administrative Agent under or in connection with any of the foregoing;
provided that no Lender shall be liable for the payment of any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements resulting solely from the
Administrative Agent's bad faith, gross negligence or willful misconduct. The
agreements in this Section 12.7 shall survive the payment of the Notes, any
Reimbursement Obligation and all other amounts payable hereunder and the
termination of this Agreement.

      SECTION 12.8      The Administrative Agent in Its Individual Capacity.
The Administrative Agent and its respective Subsidiaries and Affiliates may
make loans to, accept deposits from and generally engage in any kind of
business with the Borrower as though the Administrative Agent were not an
Administrative Agent hereunder. With respect to any Loans made or renewed by it
and any Note issued to it and with respect to any Letter of Credit issued by it
or participated in by it, the Administrative Agent shall have the same rights
and powers under this Agreement and the other Loan Documents as any Lender and
may exercise the same as though it were not an Administrative Agent, and the
terms "Lender" and "Lenders" shall include the Administrative Agent in its
individual capacity.

      SECTION 12.9      Resignation of the Administrative Agent; Successor
Administrative Agent. Subject to the appointment and acceptance of a successor
as provided below, the Administrative Agent may resign at any time by giving
notice thereof to the Lenders and the Borrower. Upon any such resignation, the
Required Lenders shall have the right to appoint a successor Administrative
Agent, which successor shall have minimum capital and surplus of at least
$500,000,000 and, so long as no Default or Event of Default has occurred and is
continuing, such appointment shall be consented to by the Borrower (which
consent shall not be unreasonably withheld or delayed). If no successor
Administrative Agent shall have been so appointed by the Required Lenders and
shall have accepted such appointment within thirty (30) days after the
Administrative Agent's giving of notice of resignation, then the Administrative
Agent may, on behalf of the Lenders, appoint a successor Administrative Agent,
which successor shall have minimum capital and surplus of at least $500,000,000
and, so long as no Default or Event of Default has occurred and is continuing,
such appointment shall be consented to by the Borrower (which consent shall not
be unreasonably withheld or delayed). Upon the acceptance of any appointment as
Administrative Agent hereunder by a successor Administrative Agent, such
successor Administrative Agent shall thereupon succeed to and become vested
with all rights, powers, privileges and duties of the retiring Administrative
Agent, and the retiring Administrative Agent shall be discharged from its
duties and obligations hereunder. After any 


                                     61
<PAGE>   67

retiring Administrative Agent's resignation hereunder as Administrative Agent,
the provisions of this Section 12.9 shall continue in effect for its benefit in
respect of any actions taken or omitted to be taken by it while it was acting
as Administrative Agent.

      SECTION 12.10     The Administrative Agent. The Administrative Agent
hereby agrees that with respect to any amendment, modification or waiver of
this Agreement and the other Loan Documents, the Administrative Agent shall be
responsible for the preparation, documentation and execution thereof. In
addition, with respect to any action or decision requiring consent or approval
of any Lenders, the Administrative Agent shall be responsible for requesting
such consent or approval from the Lenders.

                                  ARTICLE XIII

                                 MISCELLANEOUS

      SECTION 13.1      Notices.

      (a) Method of Communication. Except as otherwise provided in this
Agreement, all notices and communications hereunder shall be in writing, or by
telephone subsequently confirmed in writing. Any notice shall be effective if
delivered by hand delivery or sent via telecopy, recognized overnight courier
service or certified mail, return receipt requested, and shall be presumed to be
received by a party hereto (i) on the date of delivery if delivered by hand or
sent by telecopy, (ii) on the next Business Day if sent by recognized overnight
courier service and (iii) on the third Business Day following the date sent by
certified mail, return receipt requested. A telephonic notice to the
Administrative Agent as understood by the Administrative Agent will be deemed to
be the controlling and proper notice in the event of a discrepancy with or
failure to receive a confirming written notice.

      (b) Addresses for Notices. Notices to any party shall be sent to it at the
following addresses, or any other address as to which all the other parties are
notified in writing.

      SECTION 13.4      Governing Law. This Agreement, the Notes and the other
Loan Documents, unless otherwise expressly set forth therein, shall be governed
by, construed and enforced in accordance with the laws of the State of North
Carolina, without reference to the conflicts or choice of law principles
thereof.

      SECTION 13.5      Consent to Jurisdiction. The Borrower hereby
irrevocably consents to the personal jurisdiction of the state and federal
courts located in Mecklenburg County, North Carolina, in any action, claim or
other proceeding arising out of any dispute in connection with this Agreement,
the Notes and the other Loan Documents, any rights or obligations hereunder or
thereunder, or the performance of such rights and obligations. The Borrower
hereby irrevocably consents to the service of a summons and complaint and other
process in any action, claim or proceeding brought by the Administrative Agent
or any Lender in connection with this Agreement, the Notes or the other Loan
Documents, any rights or obligations hereunder or thereunder, or the
performance of such rights and obligations, on behalf of itself or its
property, in the manner specified in Section 13.1. Nothing in this Section 13.5
shall affect the right of the Administrative Agent or any Lender to serve legal
process in any other manner permitted by Applicable Law or affect the right of
the Administrative Agent or any Lender to bring any action or proceeding
against the Borrower or its properties in the courts of any other
jurisdictions.

      SECTION 13.6      Binding Arbitration; Waiver of Jury Trial.

      (a) Binding Arbitration. Upon demand of any party, whether made before or
after institution of any judicial proceeding, any dispute, claim or controversy
arising out of, connected with or relating to the Notes or any other Loan
Documents ("Disputes"), between or among parties to the Notes or any other Loan
Document shall be resolved by binding arbitration as 


                                     64
<PAGE>   70


provided herein. Institution of a judicial proceeding by a party does not waive
the right of that party to demand arbitration hereunder. Disputes may include,
without limitation, tort claims, counterclaims, claims brought as class
actions, claims arising from Loan Documents executed in the future, disputes as
to whether a matter is subject to arbitration, or claims concerning any aspect
of the past, present or future relationships arising out of or connected with
the Loan Documents. Arbitration shall be conducted under and governed by the
Commercial Financial Disputes Arbitration Rules (the "Arbitration Rules") of
the American Arbitration Association and Title 9 of the U.S. Code. All
arbitration hearings shall be conducted in Charlotte, North Carolina. The
expedited procedures set forth in Rule 51, et seq. of the Arbitration Rules
shall be applicable to claims of less than $1,000,000. All applicable statutes
of limitation shall apply to any Dispute. A judgment upon the award may be
entered in any court having jurisdiction. Notwithstanding anything foregoing to
the contrary, any arbitration proceeding demanded hereunder shall begin within
ninety (90) days after such demand thereof and shall be concluded within
one-hundred and twenty (120) days after such demand. These time limitations may
not be extended unless a party hereto shows cause for extension and then such
extension shall not exceed a total of sixty (60) days. The panel from which all
arbitrators are selected shall be comprised of licensed attorneys. The single
arbitrator selected for expedited procedure shall be a retired judge from the
highest court of general jurisdiction, state or federal, of the state where the
hearing will be conducted. The parties hereto do not waive any applicable
Federal or state substantive law except as provided herein. Notwithstanding the
foregoing, this paragraph shall not apply to any Hedging Agreement that is a
Loan Document.

      (b) Jury Trial. THE ADMINISTRATIVE AGENT, EACH LENDER AND THE BORROWER
HEREBY ACKNOWLEDGE THAT BY AGREEING TO BINDING ARBITRATION THEY HAVE IRREVOCABLY
WAIVED THEIR RESPECTIVE RIGHTS TO A JURY TRIAL WITH RESPECT TO ANY ACTION, CLAIM
OR OTHER PROCEEDING ARISING OUT OF ANY DISPUTE IN CONNECTION WITH THIS
AGREEMENT, THE NOTES OR THE OTHER LOAN DOCUMENTS, ANY RIGHTS OR OBLIGATIONS
HEREUNDER OR THEREUNDER, OR THE PERFORMANCE OF SUCH RIGHTS AND OBLIGATIONS.

      (c) Preservation of Certain Remedies. Notwithstanding the preceding
binding arbitration provisions, the parties hereto and the other Loan Documents
preserve, without diminution, certain remedies that such Persons may employ or
exercise freely, either alone, in conjunction with or during a Dispute. Each
such Person shall have and hereby reserves the right to proceed in any court of
proper jurisdiction or by self help to exercise or prosecute the following
remedies: (i) all rights to foreclose against any real or personal property or
other security by exercising a power of sale granted in the Loan Documents or
under Applicable Law or by judicial foreclosure and sale, (ii) all rights of
self help including peaceful occupation of property and collection of rents, set
off, and peaceful possession of property, (iii) obtaining provisional or
ancillary remedies including injunctive relief, sequestration, garnishment,
attachment, appointment of receiver and in filing an involuntary bankruptcy
proceeding, and (iv) when applicable, a judgment by confession of judgment.
Preservation of these remedies does not limit the power of an arbitrator to
grant similar remedies that may be requested by a party in a Dispute.

      SECTION 13.7      Reversal of Payments. To the extent the Borrower makes
a payment or payments to the Administrative Agent for the ratable benefit of
the Lenders or the Administrative Agent receives any payment or proceeds of the
collateral which payments or proceeds or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside and/or
required to be repaid to a trustee, receiver or any other party under any
bankruptcy law, state or federal law, common law or equitable cause, then, to
the extent of such payment or proceeds repaid, the Obligations or part thereof
intended to be satisfied shall be revived and continued in full force and
effect as if such payment or proceeds had not been received by the
Administrative Agent.

      SECTION 13.8      Injunctive Relief; Punitive Damages.

      (a) The Borrower recognizes that, upon an Event of Default, any remedy of
law may prove to be inadequate relief to the Lenders. Therefore, the Borrower
agrees that the Lenders, at the Lenders' option, shall be entitled to temporary
and permanent injunctive relief in any such case without the necessity of
proving actual damages.

      (b) The Administrative Agent, Lenders and the Borrower (on behalf of
itself and its Subsidiaries) hereby agree that no such Person shall have a
remedy of punitive or exemplary damages against any other party to a Loan
Document and each such Person hereby waives any right or claim to punitive or
exemplary damages that they may now have or may arise in the future in
connection with any Dispute, whether such Dispute is resolved through
arbitration or judicially.

      (c) The parties agree that they shall not have a remedy of punitive or
exemplary damages against any other party in any Dispute and hereby waive any
right or claim to punitive or exemplary damages they have now or which may arise
in the future in connection with any Dispute whether the Dispute is resolved by
arbitration or judicially.

      SECTION 13.9      Accounting Matters. All financial and accounting
calculations, measurements and computations made for any purpose relating to
this Agreement, including, without limitation, all computations utilized by the
Borrower or any Subsidiary thereof to determine compliance with any covenant
contained herein, shall, except as otherwise expressly contemplated hereby or
unless there is an express written direction by the Administrative Agent to the
contrary agreed to by the Borrower, be performed in accordance with GAAP as in
effect on the Closing Date. In the event that changes in GAAP shall be mandated
by the Financial Accounting Standards Board, or any similar accounting body of
comparable standing, or shall be recommended by the Borrower's certified public
accountants, to the extent that such changes would modify such accounting terms
or the interpretation or computation thereof, such changes shall be followed in
defining such accounting terms only from and after the date the Borrower and
the Lenders shall have amended this Agreement to the extent necessary to
reflect any such changes in the financial covenants and other terms and
conditions of this Agreement.

      SECTION 13.10     Successors and Assigns; Participations.

      (a) Benefit of Agreement. This Agreement shall be binding upon and inure
to the benefit of the Borrower, the Administrative Agent and the Lenders, all
future holders of the Notes, and their respective successors and assigns, except
that the Borrower shall not assign or transfer any of its rights or obligations
under this Agreement without the prior written consent of each Lender.

      (b) Assignment by Lenders. Each Lender may, with the consent of the
Borrower (so long as no Default or Event of Default has occurred and is
continuing) and the consent of the Administrative Agent, which consents shall
not be unreasonably withheld, assign to one or more Eligible Assignees all or a
portion of its interests, rights and obligations under this Agreement
(including, without limitation, all or a portion of the Extensions of Credit at
the time owing to it and the Notes held by it); provided that:

               (i) each such assignment shall be of a constant, and not a
varying, percentage of all the assigning Lender's rights and obligations under
this Agreement;

              (ii) if less than all of the assigning Lender's Commitment is to
be assigned, the Commitment so assigned shall not be less than $5,000,000;

             (iii) the parties to each such assignment shall execute and deliver
to the Administrative Agent, for its acceptance and recording in the Register,
an Assignment and Acceptance in the form of Exhibit G attached hereto (an
"Assignment and Acceptance"), together with any Note or Notes subject to such
assignment;

              (iv) such assignment shall not, without the consent of the
Borrower, require the Borrower to file a registration statement with the
Securities and Exchange Commission or apply to or qualify the Loans or the Notes
under the blue sky laws of any state; and

               (v) the assigning Lender shall pay to the Administrative Agent an
assignment fee of $3,000 upon the execution by such Lender of the Assignment and
Acceptance; provided that no such fee shall be payable upon any assignment by a
Lender to an Affiliate thereof.

Upon such execution, delivery, acceptance and recording, from and after the
effective date specified in each Assignment and Acceptance, which effective date
shall be at least five (5) Business Days after the execution thereof, (A) the
assignee thereunder shall be a party hereto and, to the extent provided in such
Assignment and Acceptance, have the rights and obligations of a Lender hereby
and (B) the Lender thereunder shall, to the extent provided in such assignment,
be released from its obligations under this Agreement.

      (c) Rights and Duties Upon Assignment. By executing and delivering an
Assignment and Acceptance, the assigning Lender thereunder and the assignee
thereunder confirm to and 


                                     67
<PAGE>   73

agree with each other and the other parties hereto as set forth in such
Assignment and Acceptance.

      (d) Register. The Administrative Agent shall maintain a copy of each
Assignment and Acceptance delivered to it and a register for the recordation of
the names and addresses of the Lenders and the amount of the Extensions of
Credit with respect to each Lender from time to time (the "Register"). The
entries in the Register shall be conclusive, in the absence of manifest error,
and the Borrower, the Administrative Agent and the Lenders may treat each person
whose name is recorded in the Register as a Lender hereunder for all purposes of
this Agreement. The Register shall be available for inspection by the Borrower
or any Lender at any reasonable time and from time to time upon reasonable prior
notice.

      (e) Issuance of New Notes. Upon its receipt of an Assignment and
Acceptance executed by an assigning Lender and an Eligible Assignee together
with any Note or Notes subject to such assignment and the written consent to
such assignment as provided in Section 13.10(b), the Administrative Agent shall,
if such Assignment and Acceptance has been completed and is substantially in the
form of Exhibit G:

               (i) accept such Assignment and Acceptance;

              (ii) record the information contained therein in the Register;

             (iii) give prompt notice thereof to the Lenders and the Borrower;
and

              (iv) promptly deliver a copy of such Assignment and Acceptance to
the Borrower.

Within five (5) Business Days after receipt of a copy of such Assignment and
Acceptance, the Borrower shall execute and deliver to the Administrative Agent,
in exchange for the surrendered Note or Notes, a new Note or Notes to the order
of such Eligible Assignee in amounts equal to the Commitment assumed by it
pursuant to such Assignment and Acceptance and a new Note or Notes to the order
of the assigning Lender in an amount equal to the Commitment retained by it
hereunder. Such new Note or Notes shall be in an aggregate principal amount
equal to the aggregate principal amount of such surrendered Note or Notes,
shall be dated the effective date of such Assignment and Acceptance and shall
otherwise be in substantially the form of the assigned Notes delivered to the
assigning Lender. Each surrendered Note or Notes shall be canceled and returned
to the Borrower.

      (f) Participations. Each Lender may sell participations to one or more
banks or other entities in all or a portion of its rights and obligations under
this Agreement (including, without limitation, all or a portion of its
Extensions of Credit and the Notes held by it); provided that:

               (i) each such participation shall be in an amount not less than
$5,000,000;


                                     68
<PAGE>   74


              (ii) such Lender's obligations under this Agreement (including,
without limitation, its Commitment) shall remain unchanged;

             (iii) such Lender shall remain solely responsible to the other
parties hereto for the performance of such obligations;

              (iv) such Lender shall remain the holder of the Notes held by it
for all purposes of this Agreement;

               (v) the Borrower, the Administrative Agent and the other Lenders
shall continue to deal solely and directly with such Lender in connection with
such Lender's rights and obligations under this Agreement;

              (vi) such Lender shall not permit such participant the right to
approve any waivers, amendments or other modifications to this Agreement or any
other Loan Document other than waivers, amendments or modifications which would
reduce the principal of or the interest rate on any Loan or Reimbursement
Obligation, extend the term or increase the amount of the Commitment (except as
expressly permitted pursuant to Section 2.8), reduce the amount of any fees to
which such participant is entitled, extend any scheduled payment date for
principal of any Loan or, except as expressly contemplated hereby or thereby,
release substantially all of the Collateral; and

             (vii) any such disposition shall not, without the consent of the
Borrower, require the Borrower to file a registration statement with the
Securities and Exchange Commission to apply to qualify the Loans or the Notes
under the blue sky law of any state.

      (g) Disclosure of Information; Confidentiality. The Administrative Agent
and the Lenders shall hold all non-public information with respect to the
Borrower or any Subsidiary thereof obtained pursuant to the Loan Documents in
accordance with their customary procedures for handling confidential
information; provided, that the Administrative Agent may disclose information
relating to this Agreement to Gold Sheets and other similar bank trade
publications, such information to consist of deal terms and other information
customarily found in such publications and provided further, that the
Administrative Agent and Lenders may disclose any such information to the
extent such disclosure is required by law or requested by any regulatory
authority. Any Lender may, in connection with any assignment, proposed
assignment, participation or proposed participation pursuant to this Section
13.10, disclose to the assignee, participant, proposed assignee or proposed
participant, any information relating to the Borrower, or any Subsidiary
thereof, furnished to such Lender by or on behalf of the Borrower or any
Subsidiary thereof; provided, that prior to any such disclosure, each such
assignee, proposed assignee, participant or proposed participant shall agree
with the Borrower or such Lender (which in the case of an agreement with only
such Lender, the Borrower shall be recognized as a third party beneficiary
thereof) to preserve the confidentiality of any confidential information
relating to the Borrower or any Subsidiary thereof received from such Lender.

affecting the validity or enforceability of such provision in any other
jurisdiction.

                               SECTION 2.GUARANTY

         2.1     Guaranty.  (a) Each of the Guarantors hereby, jointly and
severally, unconditionally and irrevocably, guarantees to the Administrative
Agent, for the ratable benefit of itself and the Lenders and their respective
successors, endorsees, transferees and assigns, the prompt and complete payment
and performance by the Borrower when due (whether at the stated maturity, by
acceleration or otherwise) of the Borrower Obligations, provided, that
notwithstanding anything to the contrary contained herein, it is the intention
of each Guarantor and the Lenders that in any proceeding involving the
bankruptcy, reorganization, arrangement, adjustment of debts, relief of debtors,
dissolution or insolvency or any similar proceeding with respect to any
Guarantor or its assets, the amount of such Guarantor's Guarantor Obligations
shall be in, but not in excess of, the maximum amount thereof not subject to
avoidance or recovery by operation of Applicable Insolvency Laws.  To that end,
but only in the event and to the extent that such Guarantor's Guarantor
Obligations or any payment made pursuant to such 


                                      7
<PAGE>   12

Guarantor Obligations would, but for the operation of the foregoing proviso, be
subject to avoidance or recovery in any such proceeding under Applicable
Insolvency Laws, the amount of such Guarantor's Guarantor Obligations shall be
limited to the largest amount which, after giving effect thereto, would not,
under Applicable Insolvency Laws, render such Guarantor's Guarantor Obligations
unenforceable or avoidable or otherwise subject to recovery under Applicable
Insolvency Laws.  To the extent any payment actually made pursuant to the
Guarantor Obligations exceeds the limitation of the foregoing proviso and is
otherwise subject to avoidance and recovery in any such proceeding under
Applicable Insolvency Laws, the amount subject to avoidance shall in all events
be limited to the amount by which such actual payment exceeds such limitation
and the Guarantor Obligations as limited by the foregoing proviso shall in all
events remain in full force and effect and be fully enforceable against such
Guarantor.  The foregoing proviso is intended solely to preserve the rights of
the Administrative Agent hereunder against such Guarantor in such proceeding to
the maximum extent permitted by Applicable Insolvency Laws, and the foregoing
proviso does not constitute nor shall it be construed as an acknowledgment that
such Guarantor, the Borrower, or any other guarantor or any other Person has or
shall have any right or claim under Applicable Insolvency Laws in such
proceeding.

         (a)     Each Guarantor agrees that the Borrower Obligations may at any
time and from time to time exceed the amount of the liability of such Guarantor
hereunder without impairing the guaranty contained in this Section 2 or
affecting the rights and remedies of the Administrative Agent or any Lender
hereunder.

         (b)     The guaranty contained in this Section 2 shall remain in full
force and effect until all the Borrower Obligations and all the Guarantor
Obligations shall have been satisfied by indefeasible payment and performance
in full, no Letter of Credit shall be outstanding and the Commitments shall be
terminated, notwithstanding that from time to time during the term of the
Credit Agreement the Borrower may be free from any Borrower Obligations.

         (c)     No payment made by the Borrower, any of the Guarantors, any
other guarantor or any other Person or received or collected by the
Administrative Agent or any Lender from the Borrower, any of the Guarantors,
any other guarantor or any other Person by virtue of any action or proceeding
or any set-off or appropriation or application at any time or from time to time
in reduction of or in payment of the Borrower Obligations shall be deemed to
modify, reduce, release or otherwise affect the liability of any Guarantor
hereunder which shall, notwithstanding any such payment (other than any payment
made by such Guarantor in respect of the Borrower Obligations or any payment
received or collected from such Guarantor in respect of the Borrower
Obligations), remain liable for the Borrower Obligations up to the maximum
liability of such Guarantor hereunder until the Borrower Obligations are paid
in full, no Letter of Credit shall be outstanding and the Commitments are
terminated.

         2.2     Right of Contribution. To the extent that the value (whether
determined under a standard of "fair value," "reasonably equivalent value" or
any other valuation standard under applicable law) of the benefit received by
any Guarantor by reason of the matters described in the preamble to this
Agreement is determined to be less than the Obligations incurred by such
Guarantor, then each other Guarantor agrees that such Guarantor shall have a
present right of contribution against such other Guarantor which right shall be
no less enforceable than the 

                                      8
<PAGE>   13

Obligations incurred by each Guarantor under this Agreement.  To that end, in
the event any Guarantor is required, by reason of this Agreement, to pay an
amount in excess of the value of the benefit such Guarantor is deemed to have
received by reason of matters described in the preamble of this Agreement, the
remaining Guarantors jointly and severally agree to pay such Guarantor, upon
demand, the amount of such excess.  Subject only to the provisions of the
following Section 2.3, such Guarantor shall be subrogated to any and all rights
of the Administrative Agent and the Lenders against the remaining Guarantors and
the Borrower to the extent of such excess payment.

         2.3     No Subrogation.  Notwithstanding any payment made by any
Guarantor hereunder or any set-off or application of funds of any Guarantor by
the Administrative Agent or any Lender, no Guarantor shall be entitled to be
subrogated to any of the rights of the Administrative Agent or any Lender
against the Borrower or any other Guarantor or any collateral security or
guaranty or right of offset held by the Administrative Agent or any Lender for
the payment of the Borrower Obligations, nor shall any Guarantor seek or be
entitled to seek any contribution or reimbursement from the Borrower or any
other Guarantor in respect of payments made by such Guarantor hereunder, until
all amounts owing to the Administrative Agent and the Lenders by the Borrower
on account of the Borrower Obligations are paid in full, no Letter of Credit
shall be outstanding and the Commitments are terminated.  If any amount shall
be paid to any Guarantor on account of such subrogation rights at any time when
all of the Borrower Obligations shall not have been paid in full, such amount
shall be held by such Guarantor in trust for the Administrative Agent and the
Lenders, segregated from other funds of such Guarantor, and shall, forthwith
upon receipt by such Guarantor, be turned over to the Administrative Agent in
the exact form received by such Guarantor (duly indorsed by such Guarantor to
the Administrative Agent, if required), to be applied against the Borrower
Obligations, whether matured or unmatured, in such order as the Administrative
Agent may determine.

         2.4     Amendments, etc.  with respect to the Borrower Obligations.
Each Guarantor shall remain obligated hereunder notwithstanding that, without
any reservation of rights against any Guarantor and without notice to or
further assent by any Guarantor, any demand for payment of any of the Borrower
Obligations made by the Administrative Agent or any Lender may be rescinded by
the Administrative Agent or such Lender and any of the Borrower Obligations
continued, and the Borrower Obligations, or the liability of any other Person
upon or for any part thereof, or any collateral security or guaranty therefor
or right of offset with respect thereto, may, from time to time, in whole or in
part, be renewed, extended, amended, modified, accelerated, compromised, waived,
surrendered or released by the Administrative Agent or any Lender, and the
Credit Agreement and the other Loan Documents and any other documents executed
and delivered in connection therewith may be amended, modified, supplemented or
terminated, in whole or in part, as the Administrative Agent (or the Required
Lenders or all Lenders, as the case may be) may deem advisable from time to
time, and any collateral security, guarantee or right of offset at any time held
by the Administrative Agent or any Lender for the payment of the Borrower
Obligations may be sold, exchanged, waived, surrendered or released.  Neither
the Administrative Agent nor any Lender shall have any obligation to protect,
secure, perfect or insure any Lien at any time held by it as security for the
Borrower Obligations or for the guaranty contained in this Section 2 or any
property subject thereto.

                                      9
<PAGE>   14

         2.5     Guarantee Absolute and Unconditional. Each Guarantor waives
any and all notice of the creation, renewal, extension or accrual of any of the
Borrower Obligations and notice of or proof of reliance by the Administrative
Agent or any Lender upon the guaranty contained in this Section 2 or acceptance
of the guaranty contained in this Section 2; the Borrower Obligations, and any
of them, shall conclusively be deemed to have been created, contracted or
incurred, or renewed, extended, amended or waived, in reliance upon the
guaranty contained in this Section 2; and all dealings between the Borrower and
any of the Guarantors, on the one hand, and the Administrative Agent and the
Lenders, on the other hand, likewise shall be conclusively presumed to have
been had or consummated in reliance upon the guaranty contained in this Section
2.  To the extent permitted by law, each Guarantor expressly waives all rights
it may now or in the future have under any statute (including, without
limitation, North Carolina General Statutes Section 26-7, et seq. or similar
law).  Each Guarantor waives diligence, presentment, protest, demand for
payment and notice of default or nonpayment to or upon the Borrower or any of
the Guarantors with respect to the Borrower Obligations.  Each Guarantor
understands and agrees that the guaranty contained in this Section 2 shall be
construed as a continuing, absolute and unconditional guaranty of payment
without regard to (a) the validity or enforceability of the Credit Agreement or
any other Loan Document, any of the Borrower Obligations or any other
collateral security therefor or guaranty or right of offset with respect
thereto at any time or from time to time held by the Administrative Agent or
any Lender, (b) any defense, set-off or counterclaim (other than a defense of
payment or performance) which may at any time be available to or be asserted by
the Borrower or any other Person against the Administrative Agent or any
Lender, or (c) any other circumstance whatsoever (with or without notice to or
knowledge of the Borrower or such Guarantor) which constitutes, or might be
construed to constitute, an equitable or legal discharge of the Borrower for
the Borrower Obligations, or of such Guarantor under the guaranty contained in
this Section 2, in bankruptcy or in any other instance.  When making any demand
hereunder or otherwise pursuing its rights and remedies hereunder against any
Guarantor, the Administrative Agent or any Lender may, but shall be under no
obligation to, make a similar demand on or otherwise pursue such rights and
remedies as it may have against the Borrower, any other Guarantor or any other
Person or against any collateral security or guaranty for the Borrower
Obligations or any right of offset with respect thereto, and any failure by the
Administrative Agent or any Lender to make any such demand, to pursue such
other rights or remedies or to collect any payments from the Borrower, any
other Guarantor or any other Person or to realize upon any such collateral
security or guaranty or to exercise any such right of offset, or any release of
the Borrower, any other Guarantor or any other Person or any such collateral
security, guaranty or right of offset shall not relieve any Guarantor of any

remedies, whether express, implied or available as a matter of law, of the
Administrative Agent or any Lender against any Guarantor. For the purposes
hereof "demand" shall include the commencement and continuance of any legal

         2.6     Reinstatement.  The guaranty contained in this Section 2 shall
continue to be effective, or be reinstated, as the case may be, if at any time

ratable benefit of the Administrative Agent and the Lenders, a security
interest in, all of the following property now owned or at any time hereafter

                                      11

<PAGE>   16

                 (n)      to the extent not otherwise included, all Proceeds
         and products of any and all of the foregoing and all collateral
         security and guaranties given by any Person with respect to any of the
         foregoing.

         Notwithstanding the foregoing and anything contained in any one or
         more of the Loan Documents to the contrary, it is agreed that the
         Grantors shall not be deemed to have granted a security interest in
         the following:  (i) any Copyright and Copyright Licenses and Trademark
         and Trademark Licenses for any foreign country, except Canada, owned
         by any Grantor, (ii) any of Leased Sites listed on Schedule 8.12(c) to
         the Credit Agreement until such time as the approvals, authorizations,
         or consents therefore have been obtained pursuant to Section 8.12(c)
         of the Credit Agreement, (iii) any Leased Sites which do not appear on
         Schedule 8.12(c), and (iv) any Material Contracts other than the
         NETCOM Network Services Agreement and the WorldCom Network Services
         Agreement and the Leased Sites (which shall be treated pursuant to
         clause (ii) above).  In addition, security interest granted hereby is
         granted only to the extent that the grant by such Grantor in its
         right, title and interest in any contract, agreement, instrument or
         indenture (a) is not prohibited by such contract, agreement,
         instrument or indenture without the consent of any other party
         thereto, (b) would not give any other party to such contract,
         agreement, instrument or indenture the right to terminate its
         obligations thereunder, or (c) is permitted with consent if all
         necessary consents to such grant of a security interest have been
         obtained from the other parties thereto; provided that the foregoing
         limitation shall not affect, limit, restrict or impair the grant by
         such Grantor of a security interest pursuant to this Agreement in any
         Account or any money or other amounts due or to become due under any
         such contract, agreement, instrument or indenture.

         3.2     Stock Powers.  Concurrently with the execution of this
Agreement and the delivery to the Administrative Agent of each certificate
representing one or more shares of Pledged Stock, each Grantor shall deliver an
undated stock power covering such certificate, duly executed in blank by such
Grantor with, if the Administrative Agent so requests, signature guaranteed.

         3.3     Control Agreement; Acknowledgement by Issuers.

         (a)     The Grantors hereby authorize and instruct each Issuer and
Partnership/LLC to comply, and each Issuer and Partnership/LLC hereby agrees to
so comply, with any instruction received thereby from the Administrative Agent
in accordance with the terms of this Agreement with respect to the Collateral,
without any consent or further instructions from such Grantor (or other
registered owner), and such Grantor agrees that such Issuer and Partnership/LLC
shall be fully protected in so complying.  Each Issuer and Partnership/LLC
agrees that its agreement set forth in the preceding sentence shall be
sufficient to create in favor of the Administrative Agent, for the benefit of
the Lenders, "control" of the Partnership/LLC Interests within the meaning of
such term under Section 8-106(c) of the UCC.  (Notwithstanding the foregoing,
nothing in this Agreement is intended or shall be construed to mean or imply
that the Partnership/LLC Interests constitute "securities" within the meaning
of such term under Section 8-102(a)(15) of the UCC or otherwise to limit or
modify the application of Section 8-103(c) of the UCC.  Rather, the
Administrative Agent has requested that this provision be included in this
Agreement solely out of an abundance of 


                                      12
<PAGE>   17

caution in the event the Partnership/LLC Interests are, nevertheless, deemed to
constitute "securities" under the UCC.)

         (b)     Each Issuer and Partnership/LLC acknowledges receipt of a copy
of this Agreement and agrees to be bound thereby and to comply with the terms
thereof  insofar as such terms are applicable to it.  Each Issuer and
Partnership/LLC agrees to notify the Administrative Agent promptly in writing
of the occurrence of any of the events described in Section 5.7(d) of this
Agreement.  Each Issuer and Partnership/LLC further agrees that the terms of
Section 6.6 of this Agreement shall apply to it with respect to all actions
that may be required of it under or pursuant to or arising out of Section 6.6
of this Agreement.

                    SECTION 4.REPRESENTATIONS AND WARRANTIES

Credit Agreement required pursuant to Section 8.12 of the Credit Agreement) and
is duly qualified and authorized to do business in each jurisdiction in which
the character of its properties or the nature of its business requires such

         4.2     Binding Obligation.

         (a)     Each Grantor has the corporate right, power and authority to
execute, deliver and perform this Agreement and has taken all necessary

availability of equitable remedies.

         (c)     The execution, delivery and performance by the Grantors of
this Agreement will not violate any material provision of any Applicable Law or
Material Contract of any Grantor and will not result in the creation or

other than Liens arising under the Loan Documents.

the Grantors will not (i) vote to enable, or take any other action to permit,
any Issuer or Partnership/LLC to issue any stock, partnership interests,
limited liability company interests or other equity securities of any nature or
to issue any other securities convertible into or granting the right to
purchase or exchange for any stock, partnership interests, limited liability
company interests or other equity securities of any nature of such Issuer or
Partnership/LLC, (ii) except as expressly provided to the contrary herein,
consent to any modification, extension or alteration of the terms of any
partnership agreement or operating agreement of the Partnerships/LLCs, (iii)
accept a surrender of any partnership agreement or operating agreement of any
of the Partnerships/LLCs or waive any breach of or default under any
partnership agreement or operating agreement of any of the Partnerships/LLCs by
any other party thereto, (iv) sell, assign, transfer, exchange, or otherwise
dispose of, or grant any option with respect to, the Collateral, or (v) create,
incur or permit to exist any Lien or option in favor of, or any claim of any
Person with respect to, any of the Collateral, or any interest therein, except
for the Lien provided for by this Agreement and by Permitted Liens.  The
Grantors will defend the right, title and interest of the Administrative Agent
in and to the Collateral against the claims and demands of all Persons
whomsoever.

         (d)     If such Grantor shall become entitled to receive or shall
receive any stock certificate (including, without limitation, any certificate
representing a stock dividend or a distribution in connection with any
reclassification, increase or reduction of capital or any certificate issued in
connection with any reorganization), option or rights in respect of the capital
stock of any Issuer, whether in addition to, in substitution of, as a
conversion of, or in exchange for, any shares of the Pledged Stock, or
otherwise in respect thereof, such Grantor shall accept the same as the agent
of the Administrative Agent and the Lenders, hold the same in trust for the
Administrative Agent and the Lenders and deliver the same forthwith to the
Administrative Agent in the exact form received, duly indorsed by such Grantor
to the Administrative Agent, if required, together with an undated stock power
covering such certificate duly executed in blank by such Grantor and with, if
the Administrative Agent so requests, signature guaranteed, to be held by the
Administrative Agent, subject to the terms hereof, as additional collateral
security for the Obligations.  Any sums paid upon or in respect of the
Investment Property upon the liquidation or dissolution of any Issuer shall be
paid over to the Administrative Agent to be held by it hereunder as additional
collateral security for the Obligations, and in case any distribution of
capital shall be made on or in respect of the Investment Property or any
property shall be distributed upon or with respect to the Investment Property
pursuant to the recapitalization or reclassification of the capital of any
Issuer or pursuant to the reorganization thereof, the property so distributed
shall, unless otherwise subject to a perfected security interest in favor of
the Administrative Agent, be delivered to the Administrative Agent to be held
by it hereunder as 


                                      20
<PAGE>   25

additional collateral security for the Obligations.  If any sums of money or
property so paid or distributed in respect of the Investment Property shall be
received by such Grantor, such Grantor shall, until such money or property is
paid or delivered to the Administrative Agent, hold such money or property in
trust for the Lenders, segregated from other funds of such Grantor, as
additional collateral security for the Obligations.

         (e)     In the case of each Grantor which is an Issuer, such Issuer
agrees that (i) it will be bound by the terms of this Agreement relating to the
Investment Property issued by it and will comply with such terms insofar as
such terms are applicable to it, (ii) it will notify the Administrative Agent
promptly in writing of the occurrence of any of the events described in Section
5.7(d) with respect to the Investment Property issued by it and (iii) the terms
of Section 6.3(c) and Section 6.7 shall apply to it, mutatis mutandis with
respect to all actions that may be required of it pursuant to Section 6.3(c) or
Section 6.7 with respect to the Investment Property issued by it.

         5.8     Accounts.

         (a)     Other than in the ordinary course of business consistent with
its past practice, such Grantor will not (i) grant any extension of the time of
payment of any Account with a face amount in excess of $50,000, (ii) compromise
or settle any Account with a face amount in excess of $50,000 for less than the
full amount thereof, (iii) release, wholly or partially, any Person liable for
the payment of any Account with a face amount in excess of $50,000, (iv) allow
any credit or discount whatsoever on any Account with a face amount in excess of
$50,000 or (v) amend, supplement or modify any Account with a face amount in
excess of $50,000 in any manner that could materially adversely affect the value
thereof.

         (b)     Such Grantor will deliver to the Administrative Agent a copy
of each material demand, notice or document received by it that questions or
calls into doubt the validity or enforceability of any material Account.

         5.9     Deposit Accounts.

         (a)     Each Grantor shall maintain on and after the Closing Date its
Deposit Accounts with a financial institution listed on Schedule 5 or at such
other financial institution reasonably acceptable to the Administrative Agent
and the Required Lenders, each of which financial institutions (other than
First Union) shall have executed a Depository Account Agreement in
substantially the form of Exhibit B hereto (any such institution a "Controlled
Depository").  Upon the occurrence or during the continuance of a Default or
Event of Default, whenever any Grantor shall receive any monies, checks or any
other items of payment relating to, or proceeds of, Accounts, such Grantor
agrees with the Administrative Agent and Lenders that it will, consistent with
Grantor's business practice, deposit all such items of payment into a Deposit
Account at First Union or at a Controlled Depository.  Upon receipt, such
Grantor shall hold such items of payment in trust for the Administrative Agent
and Lenders and as property of the Administrative Agent and Lenders, separate
from the other funds of such Grantor, until such Grantor shall deposit the same
in a Depository Account as provided above.



                                      21
<PAGE>   26

         (b)     Upon the occurrence or during the continuance of a Default or
Event of Default, each Grantor shall forward to the Administrative Agent, on
the last Business Day of each week, deposit slips related to all such items of
payment received by the Grantor during such week, and, if requested by the
Administrative Agent, copies of such checks and other items, together with a
statement showing the application of all payments on the Accounts during such
week and a collection report with regard thereto in form and substance
satisfactory to the Administrative Agent.

         (c)     The Administrative Agent shall have the right (but not the
obligation) to apply any funds held in any Deposit Account to the repayment of
any Obligations then due and payable in the order set forth in Section 4.5 of
the Credit Agreement.

         (d)     Upon the occurrence and during the continuance of an Event of
Default, the Administrative Agent shall have the right in accordance with
Section 6 to transfer or direct the transfer of the balance of each Deposit
Account to the Collateral Account.

         5.10    Material Contracts.

         (a)     Such Grantor will perform and comply in all material respects
with all its material obligations under the Material Contracts.

         (b)     Such Grantor will not amend, modify, terminate or waive any
material provision of any Material Contract in any manner which could
reasonably be expected to materially adversely affect the value of such
Material Contract as Collateral.

         (c)     Such Grantor will exercise promptly and diligently each and
every material right which it may have under each Material Contract (other than
any right of termination).

         (d)     Such Grantor will deliver to the Administrative Agent a copy
of each material demand, notice or document received by it relating in any way
to any Material Contract that questions the validity or enforceability of such
Material Contract.

         5.11    Intellectual Property.

         (a)     Such Grantor (either itself or through licensees) will (i)
continue to use each material Trademark on each and every trademark class of
goods applicable to its current line as reflected in its current catalogs,
brochures and price lists in order to maintain such Trademark in full force
free from any claim of abandonment for non-use, (ii) maintain as in the past
the quality of products and services offered under such material Trademark,
(iii) use such material Trademark with the appropriate notice of registration
and all other notices and legends required by Applicable Laws, (iv) not adopt
or use any mark which is confusingly similar or a colorable imitation of such
material Trademark unless the Administrative Agent, for the ratable benefit of
itself and the Lenders, shall obtain a perfected security interest in such mark
pursuant to this Agreement; and (v) not (and not permit any licensee or
sublicensee thereof to) do any act or knowingly omit to do any act whereby such
material Trademark may become invalidated or impaired in any way.



                                      22
<PAGE>   27

         (b)     Such Grantor (either itself or through licensees) will not do
any act; or omit to do any act, whereby any material Patent may become
forfeited, abandoned or dedicated to the public.

         (c)     Such Grantor (either itself or through licensees) (i) will
employ each material Copyright and (ii) will not (and will not permit any
licensee or sublicensee thereof to) do any act or knowingly omit to do any act
whereby any material portion of the Copyrights may become invalidated or
otherwise impaired.  Such Grantor will not (either itself or through licensees)
do any act whereby any material portion of the Copyrights may fall into the
public domain.

         (d)     Such Grantor (either itself or through licensees) will not do
any act that knowingly uses any material Intellectual Property to infringe the
intellectual property rights of any other Person.

         (e)     Such Grantor will notify the Administrative Agent and the
Lenders immediately if it knows, or has reason to know, that any application or
registration relating to any material Intellectual Property may become
forfeited, abandoned or dedicated to the public, or of any adverse
determination or development (including, without limitation, the institution
of, or any such determination or development in, any proceeding in the United
States Patent and Trademark Office, the United States Copyright Office or any
court or tribunal in any country) regarding such Grantor's ownership of, or the
validity of, any material Intellectual Property or such Grantor's right to
register the same or to own and maintain the same.

         (f)     Whenever such Grantor, either by itself or through any agent,
employee, licensee or designee, shall file an application for the registration
of any Intellectual Property with the United States Patent and Trademark
Office, the United States Copyright Office or any similar office or agency in
any other country or any political subdivision thereof, such Grantor shall
report such filing to the Administrative Agent within five Business Days after
the last day of the fiscal quarter in which such filing occurs.  Upon request
of the Administrative Agent, such Grantor shall execute and deliver, and have
recorded, any and all agreements, instruments, documents, and papers as the
Administrative Agent may reasonably request to evidence the Administrative
Agent's and the Lenders' security interest in any Copyright, Patent or
Trademark and the goodwill and general intangibles of such Grantor relating
thereto or represented thereby.

         (g)     With respect to the material Intellectual Property, such
Grantor will take all reasonable and necessary steps, including, without
limitation, in any proceeding before the United States Patent and Trademark
Office, the United States Copyright Office or any similar office or agency in
any other country or any political subdivision thereof, to maintain and pursue
each application (and to obtain the relevant registration) and to maintain each
registration of the material Intellectual Property, including, without
limitation, filing of applications for renewal, affidavits of use and
affidavits of incontestability.

         (h)     In the event that any material Intellectual Property is
infringed, misappropriated or diluted by a third party, such Grantor shall (i)
take such actions as such Grantor shall reasonably deem appropriate under the
circumstances to protect such Intellectual Property and (ii) if such
Intellectual Property is of material economic value, promptly notify the



                                      23
<PAGE>   28

Administrative Agent after it learns thereof and sue for infringement,
misappropriation or dilution, to seek injunctive relief where appropriate and
to recover any and all damages for such infringement, misappropriation or
dilution.

         5.12    Inventory.  Each Grantor will maintain each item of Equipment
in good working order and condition (reasonable wear and tear and obsolescence
excepted), and within a reasonable time will make or cause to be made all
maintenance, service and repairs necessary for such purpose and will promptly
furnish to the Administrative Agent a statement respecting any material loss or
damage to any of the Equipment.

         5.13    Regulatory Approvals.  Each Grantor will, at its expense,
promptly execute and deliver, or cause the execution and delivery of, all
applications, certificates, instruments, registration statements, and all other
documents and papers the Administrative Agent may reasonably request and as may
be required by law in connection with the obtaining of any consent, approval,
registration, qualification, or authorization of any Person deemed necessary or
appropriate for the effective exercise of any rights under this Agreement.
Without limiting the generality of the foregoing, if an Event of Default shall
have occurred and be continuing, each Grantor shall take any action which the
Administrative Agent may reasonably request in order to transfer and assign to
the Administrative Agent, or to such one or more third parties as the
Administrative Agent may designate, or to a combination of the foregoing, each
Communications License or other Governmental Approval.  To enforce the
provisions of this Section, upon the occurrence and during the continuance of an
Event of Default, the Administrative Agent is empowered to request the
appointment of a receiver from any court of competent jurisdiction.  Such
receiver shall be instructed to seek from the Governmental Authority an
involuntary transfer of control of each such Communications License or other
Governmental Approval for the purpose of seeking a bona fide purchaser to whom
control will ultimately be transferred.  Each Grantor hereby agrees to authorize
such an involuntary assignment or transfer of control upon the request of the
receiver so appointed and, if such Grantor shall refuse to authorize the
transfer, its approval may be required by the court.  Upon the occurrence and
continuance of an Event of Default, such Grantor shall further use its
commercially reasonable to assist in obtaining approval of any Governmental
Authority, if required, for any action or transactions contemplated by this
Agreement, including, without limitation, the preparation, execution and filing
with any Governmental Authority of the assignor's or transferor's portion of any
application or applications for consent to the assignment of any Communications
License or other Governmental Approval or transfer of control necessary or
appropriate under the rules and regulations of any Governmental Authority for
the approval of the transfer or assignment of any portion of the assets of such
Grantor, together with any Communications Licenses or other Governmental
Approval.  Because such Grantor agrees that the Administrative Agent's remedy at
law for failure of such Grantor to comply with the provisions of this Section
would be inadequate and that such failure would not be adequately compensable in
damages, such Grantor agrees that the covenants contained in this Section may be
specifically enforced, and such Grantor hereby waives and agrees not to assert
any defenses against an action for specific performance of such covenants.
Notwithstanding the foregoing, the Lenders and the Administrative Agent
understand and agree that the assignment or transfer of control of some of the
Communications Licenses requires advance approval by the FCC.

                         SECTION 6.REMEDIAL PROVISIONS

         6.1     Certain Matters Relating to Accounts.

         (a)     The Administrative Agent shall have the right to make test
verifications of the Accounts in any manner and through any medium that it
reasonably considers advisable, and each Grantor shall furnish all such
assistance and information as the Administrative Agent may reasonably require
in connection with such test verifications.  At any time and from time to time,
upon the Administrative Agent's request and at the expense of the relevant
Grantor, such Grantor shall cause independent public accountants or others
reasonably satisfactory to the Administrative Agent to furnish to the
Administrative Agent reports showing reconciliations, aging and test
verifications of, and trial balances for, the Accounts.

         (b)     The Administrative Agent hereby authorizes each Grantor to
collect such Grantor's Accounts, under the Administrative Agent's direction and
control, and the Administrative Agent may curtail or terminate said authority at
any time after the occurrence and during the continuance of an Event of Default.

         (c)     At the Administrative Agent's reasonable request, each Grantor
shall deliver to the Administrative Agent all original and other documents
evidencing, and relating to, the agreements and transactions which gave rise to
the material Accounts, including, without limitation, all original orders,
invoices and shipping receipts.

         6.2     Communications with Obligors, Grantors Remain Liable.

         (a)     The Administrative Agent in its own name or in the name of
others may at any time after the occurrence and during the continuance of an
Event of Default communicate with obligors under the Accounts and parties to
the Material Contracts to verify with them to the Administrative Agent's
satisfaction the existence, amount and terms of any Accounts or Material
Contracts.

         (b)     Upon the request of the Administrative Agent at any time after
the occurrence and during the continuance of an Event of Default, each Grantor
shall notify obligors on the Accounts and parties to the Material Contracts
that the Accounts and the Material Contracts have been assigned to the
Administrative Agent for the ratable benefit of itself and the Lenders and that
payments in respect thereof shall be made directly to the Administrative Agent.

         (c)     Anything herein to the contrary notwithstanding, each Grantor
shall remain liable under each of the Accounts and Material Contracts to
observe and perform all the conditions and obligations to be observed and
performed by it thereunder, all in accordance with the terms of any agreement
giving rise thereto.  Neither the Administrative Agent nor any Lender shall
have any obligation or liability under any Account (or any agreement giving
rise thereto) or Material Contract by reason of or arising out of this
Agreement or the receipt by the Administrative Agent or any Lender of any
payment relating thereto, nor shall the Administrative Agent or any Lender be
obligated in any manner to perform any of the obligations of any Grantor under
or pursuant to any Account (or any agreement giving rise thereto) or Material
Contract to make any payment, to 


                                      25
<PAGE>   30

make any inquiry as to the nature or the sufficiency of any payment received by
it or as to the sufficiency of any performance by any party thereunder, to
present or file any claim, to take any action to enforce any performance or to
collect the payment of any amounts which may have been assigned to it or to
which it may be entitled at any time or times.

         (d)     Anything herein to the contrary notwithstanding, (a) each
Grantor shall remain liable to perform all of its duties and obligations as a
partner or member of the Partnerships/LLCs to the same extent as if this
Agreement had not been executed, (b) the exercise by the Administrative Agent
or any Lender of any of its rights hereunder shall not release such Grantor
from any of its duties or obligations as a partner or member of the
Partnerships/LLCs, and (c) neither the Administrative Agent nor any Lender
shall have any obligation or liability as a partner or member of the
Partnerships/LLCs by reason of this Agreement.

         6.3     Pledged Stock.

         (a)     Unless an Event of Default shall have occurred and be
continuing and the Administrative Agent shall have given notice to the relevant
Grantor of the Administrative Agent's intent to exercise its corresponding
rights pursuant to Section 6.3(b), each Grantor shall be permitted to receive
all cash dividends paid in respect of the Pledged Stock, Partnership/LLC
Interests and all payments made in respect of the Pledged Notes, in each case
paid in the normal course of business of the relevant Issuer and consistent
with past practice, to the extent permitted in the Credit Agreement, and to
exercise all voting and corporate, company and partnership rights with respect
to the Investment Property; provided, however, that no vote shall be cast or
corporate, company and partnership right exercised or other action taken which,
in the Administrative Agent's reasonable judgment, would impair the Collateral
or which would be inconsistent with or result in any violation of any provision
of the Credit Agreement, this Agreement or any other Loan Document.

         (b)     If an Event of Default shall occur and be continuing and the
Administrative Agent shall give notice of its intent to exercise such rights to
the relevant Grantor or Grantors, (i) the Administrative Agent shall have the
right to receive any and all cash dividends paid in respect of the Pledged
Stock, partnership and membership distributions in respect of the
Partnership/LLC Interests or other Proceeds paid in respect of the Investment
Property and make application thereof to the Obligations in the order set forth
in Section 4.5 of the Credit Agreement, and (ii) any or all of the Investment
Property shall be registered in the name of the Administrative Agent or its
nominee, and the Administrative Agent or its nominee may thereafter exercise
(A) all voting, corporate and other rights pertaining to such Investment
Property at any meeting of shareholders of the relevant Issuer or Issuers or
otherwise and (B) any and all rights of conversion, exchange and subscription
and any other fights, privileges or options pertaining to such Investment
Property as if it were the absolute owner thereof (including, without
limitation, the right to exchange at its discretion any and all of the
Investment Property upon the merger, consolidation, reorganization,
recapitalization or other fundamental change in the corporate structure of any
Issuer, or upon the exercise by any Grantor or the Administrative Agent of any
right, privilege or option pertaining to such Investment Property, and in
connection therewith, the right to deposit and deliver any and all of the
Investment Property with any committee, depositary, transfer agent, registrar
or other designated agency upon such terms and conditions as 


                                      26
<PAGE>   31

the Administrative Agent may determine), all without liability except to account
for property actually received by it; but the Administrative Agent shall have no
duty to any Grantor to exercise any such right, privilege or option and shall
not be responsible for any failure to do so or delay in so doing.

         (c)     Each Grantor hereby authorizes and instructs each Issuer of
any Investment Property pledged by such Grantor hereunder to (i) comply with
any instruction received by it from the Administrative Agent in writing that
(x) states that an Event of Default has occurred and is continuing and (y) is
otherwise in accordance with the terms of this Agreement, without any other or
further instructions from such Grantor, and each Grantor agrees that each
Issuer shall be fully protected in so complying, and (ii) unless otherwise
expressly permitted hereby, pay any dividends or other payments with respect to
the Investment Property directly to the Administrative Agent.

         6.4     Proceeds to be Turned Over To Administrative Agent.  In
addition to the rights of the Administrative Agent and the Lenders specified in
Section 6.1 with respect to payments of Accounts, if an Event of Default shall
occur and be continuing, all Proceeds received by any Grantor consisting of
cash, checks and other near-cash items shall be held by such Grantor in trust
for the Administrative Agent and the Lenders, segregated from other funds of
such Grantor, and shall, forthwith upon receipt by such Grantor, be turned over
to the Administrative Agent in the exact form received by such Grantor (duly
indorsed by such Grantor to the Administrative Agent, if required).  All
Proceeds received by the Administrative Agent hereunder shall be held by the
Administrative Agent in a Collateral Account maintained under its sole dominion
and control.  All Proceeds while held by the Administrative Agent in a
Collateral Account (or by such Grantor in trust for the Administrative Agent
and the Lenders) shall continue to be held as collateral security for all the
Obligations and shall not constitute payment thereof until applied as provided
in Section 6.5.

         6.5     Application of Proceeds.  In accordance with Section 4.5 of
the Credit Agreement, at such intervals as may be agreed upon by the Borrower
and the Administrative Agent, or, if an Event of Default shall have occurred
and be continuing, at any time at the Administrative Agent's election, the
Administrative Agent may apply all or any part of Proceeds held in any
Collateral Account in payment of the Obligations in such order as the
Administrative Agent may elect, and any part of such funds which the
Administrative Agent elects not so to apply and deems not required as
collateral security for the Obligations shall be paid over from time to time by
the Administrative Agent to the Borrower or to whomsoever may be lawfully
entitled to receive the same.  Any balance of such Proceeds remaining after the
Obligations shall have been paid in full, no Letters of Credit shall be
outstanding and the Commitments shall have terminated shall be paid over to the
Borrower or to whomsoever may be lawfully entitled to receive the same.

         6.6     Code and Other Remedies.  If an Event of Default shall occur
and be continuing, the Administrative Agent, on behalf of the Lenders, may
exercise, in addition to all other rights and remedies granted to them in this
Agreement and in any other instrument or agreement securing, evidencing or
relating to the Obligations, all rights and remedies of a secured party under
the UCC or any other applicable law.  Without limiting the generality of the
foregoing, the 


                                      27
<PAGE>   32

Administrative Agent, without demand of performance or other demand,
presentment, protest, advertisement or notice of any kind (except any notice
required by law referred to below) to or upon any Grantor or any other Person
(all and each of which demands, defenses, advertisements and notices are hereby
waived), may in such circumstances forthwith collect, receive, appropriate and
realize upon the Collateral, or any part thereof, and/or may forthwith sell,
lease, assign, give option or options to purchase, or otherwise dispose of and
deliver the Collateral or any part thereof (or contract to do any of the
foregoing), in one or more parcels at public or private sale or sales, at any
exchange, broker's board or office of the Administrative Agent or any Lender or
elsewhere upon such terms and conditions as it may deem advisable and at such
prices as it may deem best, for cash or on credit or for future delivery without
assumption of any credit risk.  The Administrative Agent or any Lender shall
have the right upon any such public sale or sales, and, to the extent permitted
by law, upon any such private sale or sales, to purchase the whole or any
part of the Collateral so sold, free of any right or equity of redemption in
any Grantor, which right or equity is hereby waived and released.  Each Grantor
further agrees, at the Administrative Agent's request, to assemble the
Collateral and make it available to the Administrative Agent at places which
the Administrative Agent shall reasonably select, whether at such Grantor's
premises or elsewhere.  The Administrative Agent shall apply the net proceeds
of any action taken by it pursuant to this Section 6.6, after deducting all
reasonable costs and expenses of every kind incurred in connection therewith or
incidental to the care or safekeeping of any of the Collateral or in any way
relating to the Collateral or the rights of the Administrative Agent and the
Lenders hereunder, including, without limitation, reasonable attorneys' fees
and disbursements, to the payment in whole or in part of the Obligations, in
the order set forth in Section 4.5 of the Credit Agreement, and only after such
application and after the payment by the Administrative Agent of any other
amount required by any provision of law, including, without limitation, Section
9-504(l)(c) of the UCC, need the Administrative Agent account for the surplus,
if any, to any Grantor.  To the extent permitted by applicable law, each
Grantor waives all claims, damages and demands it may acquire against the
Administrative Agent or any Lender arising out of the exercise by them of any
rights hereunder.  If any notice of a proposed sale or other disposition of
Collateral shall be required by law, such notice shall be deemed reasonable and
proper if given at least 10 days before such sale or other disposition.

         6.7     Registration Rights.

         (a)     If the Administrative Agent shall determine to exercise its
right to sell any or all of the Pledged Stock pursuant to Section 6.6, and if
in the opinion of the Administrative Agent it is necessary or advisable to have
the Pledged Stock, or that portion thereof to be sold, registered under the
provisions of the Securities Act, the relevant Grantor will use its best
efforts to cause the Issuer thereof to (i) execute and deliver, and cause the
directors and officers of such Issuer to execute and deliver, all such
instruments and documents, and do or cause to be done all such other acts as
may be, in the opinion of the Administrative Agent, necessary or advisable to
register the Pledged Stock, or that portion thereof to be sold, under the
provisions of the Securities Act, (ii) use its best efforts to cause the
registration statement relating thereto to become effective and to remain
effective for a period of one year from the date of the first public offering
of the Pledged Stock, or that portion thereof to be sold, and (iii) make all
amendments thereto and/or to the related prospectus which, in the opinion of
the Administrative Agent, are necessary or advisable, all in conformity with
the requirements of the Securities Act and the rules 


                                      28
<PAGE>   33

and regulations of the Securities and Exchange Commission applicable thereto. 
Each Grantor agrees to cause such Issuer to comply with the provisions of the
securities or "Blue Sky" laws of any and all jurisdictions which the
Administrative Agent shall designate and to make available to its security
holders, as soon as practicable, an earnings statement (which need not be
audited) which will satisfy the provisions of Section 11 (a) of the Securities
Act.

         (b)     Each Grantor recognizes that the Administrative Agent may be
unable to effect a public sale of any or all the Pledged Stock, by reason of
certain prohibitions contained in the Securities Act and applicable state
securities laws or otherwise, and may be compelled to resort to one or more
private sales thereof to a restricted group of purchasers which will be obliged
to agree, among other things, to acquire such securities for their own account
for investment and not with a view to the distribution or resale thereof.  Each
Grantor acknowledges and agrees that any such private sale may result in prices
and other terms less favorable than if such sale were a public sale and,
notwithstanding such circumstances, agrees that any such private sale shall be
deemed to have been made in a commercially reasonable manner.  The
Administrative Agent shall be under no obligation to delay a sale of any of the
Pledged Stock for the period of time necessary to permit the Issuer thereof to
register such securities for public sale under the Securities Act, or under
applicable state securities laws, even if such Issuer would agree to do so.

         (c)     Each Grantor agrees to use its best efforts to do or cause to
be done all such other acts as may be necessary to make such sale or sales of
all or any portion of the Pledged Stock pursuant to this Section 6.7 valid and
binding and in compliance with any and all other Applicable Laws.  Each Grantor
further agrees that a breach of any of the covenants contained in this Section
6.7 will cause irreparable injury to the Administrative Agent and the Lenders,
that the Administrative Agent and the Lenders have no adequate remedy at law in
respect of such breach and, as a consequence, that each and every covenant
contained in this Section 6.7 shall be specifically enforceable against such
Grantor, and such Grantor hereby waives and agrees not to assert any defenses
against an action for specific performance of such covenants except for a
defense that no Event of Default has occurred under the Credit Agreement.

         6.8     Waiver, Deficiency.  Each Grantor waives and agrees not to
assert any rights or privileges which it may acquire under Section 9-112 of the
UCC.  Each Grantor shall remain liable for any deficiency if the proceeds of
any sale or other disposition of the Collateral are insufficient to pay its
Obligations and the fees and disbursements of any attorneys employed by the
Administrative Agent or any Lender to collect such deficiency.

                       SECTION 7. THE ADMINISTRATIVE AGENT

         7.1     Administrative Agent's Appointment as Attorney-in-Fact, etc.

         (a)     Each Grantor hereby irrevocably constitutes and appoints the
Administrative Agent and any officer or agent thereof, with full power of
substitution, as its true and lawful attorney-in-fact with full irrevocable
power and authority in the place and stead of such Grantor and in the name of
such Grantor or in its own name, for the purpose of carrying out the terms of
this Agreement, to take any and all appropriate action and to execute any and
all documents and instruments which may be necessary or desirable to accomplish
the purposes of this Agreement, 


                                      29
<PAGE>   34

and, without limiting the generality of the foregoing, each Grantor hereby gives
the Administrative Agent the power and right, on behalf of such Grantor, without
notice to or assent by such Grantor, to do any or all of the following:

                 (i)      in the name of such Grantor or its own name, or
         otherwise, take possession of and indorse and collect any checks,
         drafts, notes, acceptances or other instruments for the payment of
         moneys due under any Account or Material Contract or with respect to
         any other Collateral and file any claim or take any other action or
         proceeding in any court of law or equity or otherwise deemed
         appropriate by the Administrative Agent for the purpose of collecting
         any and all such moneys due under any Account or Material Contract or 
         with respect to any other Collateral whenever payable;

                 (ii)     in the case of any Intellectual Property, execute and
         deliver, and have recorded, any and all agreements, instruments,
         documents and papers as the Administrative Agent may request to
         evidence the Administrative Agent's and the Lenders' security interest
         in such Intellectual Property and the goodwill and general intangibles
         of such Grantor relating thereto or represented thereby;

                 (iii)    pay or discharge taxes and Liens levied or placed on
         or threatened against the Collateral, effect any repairs or any
         insurance called for by the terms of this Agreement and pay all or any
         part of the premiums therefor and the costs thereof,

                 (iv)     execute, in connection with any sale provided for in
         Section 6.6 or Section 6.7, any endorsements, assignments or other
         instruments of conveyance or transfer with respect to the Collateral;
         and

                 (v)      (1) direct any party liable for any payment under any
         of the Collateral to make payment of any and all moneys due or to
         become due thereunder directly to the Administrative Agent or as the
         Administrative Agent shall direct; (2) ask or demand for, collect, and
         receive payment of and receipt for, any and all moneys, claims and
         other amounts due or to become due at any time in respect of or
         arising out of any Collateral; (3) sign and indorse any invoices,
         freight or express bills, bills of lading, storage or warehouse
         receipts, drafts against debtors, assignments, verifications, notices
         and other documents in connection with any of the Collateral; (4)
         commence and prosecute any suits, actions or proceedings at law or in
         equity in any court of competent jurisdiction to collect the
         Collateral or any portion thereof and to enforce any other right in
         respect of any Collateral; (5) defend any suit, action or proceeding
         brought against such Grantor with respect to any Collateral; (6)
         settle, compromise or adjust any such suit, action or proceeding and,
         in connection therewith, give such discharges or releases as the
         Administrative Agent may deem appropriate; (7) assign any Copyright,
         Patent or Trademark (along with the goodwill of the business to which
         any such Copyright, Patent or Trademark pertains), for such term or
         terms, on such conditions, and in such manner, as the Administrative
         Agent shall in its sole discretion determine; and (8) generally, sell,
         transfer, pledge and make any agreement with respect to or otherwise
         deal with any of the Collateral as fully and completely as though the
         Administrative Agent were the absolute 


                                      30
<PAGE>   35

         owner thereof for all purposes, and do, at the Administrative Agent's
         option and such Grantor's expense, at any time, or from time to time,
         all acts and things which the Administrative Agent deems necessary to 
         protect, preserve or realize upon the Collateral and the Administrative
         Agent's and the Lenders' security interests therein and to effect the 
         intent of this Agreement, all as fully and effectively as such Grantor
         might do.

         Anything in this Section 7.1(a) to the contrary notwithstanding, the
Administrative Agent agrees that it will not exercise any rights under the
power of attorney provided for in this Section 7.1(a) unless an Event of
Default shall have occurred and be continuing and the Administrative
Agent shall give such Grantor not less than ten (10) days notice of such sale
or disposition, except for the sale or disposition of perishable goods.

         (b)     If any Grantor fails to materially perform or comply with any
of its agreements contained herein, the Administrative Agent, at its option,
but without any obligation so to do, may perform or comply, or otherwise cause
performance or compliance, with such agreement.

         (c)     The expenses of the Administrative Agent incurred in
connection with actions undertaken as provided in this Section 7.1, together
with interest thereon at a rate per annum equal to the highest rate per annum
at which interest would then be payable on any category of past due Base Rate
Loans under the Credit Agreement, from the date of payment by the
Administrative Agent to the date reimbursed by the relevant Grantor, shall be
payable by such Grantor to the Administrative Agent on demand.

         (d)     Each Grantor hereby ratifies all that said attorneys shall
lawfully do or cause done by virtue hereof.  All powers, authorizations and
agencies contained in this Agreement are coupled with an interest and are
irrevocable until this Agreement is terminated and the security interests
created hereby are released.

         7.2     Duty of Administrative Agent.  The Administrative Agent's sole
duty with respect to the custody, safekeeping and physical preservation of the
Collateral in its possession, under Section 9-207 of the UCC or otherwise,
shall be to deal with it in the same manner as the Administrative Agent deals
with similar property for its own account.  Neither the Administrative Agent,
any Lender nor any of their respective officers, directors, employees or agents
shall be liable for failure to demand, collect or realize upon any of the
Collateral or for any delay in doing so or shall be under any obligation to
sell or otherwise dispose of any Collateral upon the request of any Grantor or
any other Person or to take any other action whatsoever with regard to the
Collateral or any part thereof.  The powers conferred on the Administrative
Agent and the Lenders hereunder are solely to protect the Administrative
Agent's and the Lenders' interests in the Collateral and shall not impose any
duty upon the Administrative Agent or any Lender to exercise any such powers.
The Administrative Agent and the Lenders shall be accountable only for amounts
that they actually receive as a result of the exercise of such powers, and
neither they nor any of their officers, directors, employees or agents shall be
responsible to any Grantor for any act or failure to act hereunder, except for
their own gross negligence or willful misconduct.

<PAGE>   36


         7.3     Execution of Financing Statements.  Pursuant to Section 9-402
of the UCC and any other applicable law, each Grantor authorizes the
Administrative Agent to file or record financing statements and other filing or
recording documents or instruments with respect to the Collateral without the
signature of such Grantor in such form and in such offices as the
Administrative Agent determines appropriate to perfect the security interests
of the Administrative Agent under this Agreement.  A photographic or other
reproduction of this Agreement shall be sufficient as a financing statement or
other filing or recording document or instrument for filing or recording in any
jurisdiction.

         7.4     Authority of Administrative Agent.  Each Grantor acknowledges
that the rights and responsibilities of the Administrative Agent under this
Agreement with respect to any action taken by the Administrative Agent or the
exercise or non-exercise by the Administrative Agent of any option, voting
right, request, judgment or other right or remedy provided for herein or
resulting or arising out of this Agreement shall, as between the Administrative
Agent and the Lenders, be governed by the Credit Agreement and by such other
agreements with respect thereto as may exist from time to time among them, but,
as between the Administrative Agent and the Grantors, the Administrative Agent
shall be conclusively presumed to be acting as agent for the Lenders with full
and valid authority so to act or refrain from acting, and no Grantor shall be
under any obligation, or entitlement to make any inquiry respecting such
authority.

                            SECTION 8.MISCELLANEOUS

         8.1     Amendments in Writing.  None of the terms or provisions of
this Agreement may be waived, amended, supplemented or otherwise modified
except in accordance with Section 13.11 of the Credit Agreement.

         8.2     Notices.  All notices, requests and demands to or upon the
Administrative Agent or any Grantor hereunder shall be effected in the manner
provided for in Section 13.1 of the Credit Agreement; provided that any such
notice, request or demand to or upon any Guarantor shall be addressed to such
Guarantor at its notice address set forth on Schedule 1.

         8.3     No Waiver by Course of Conduct; Cumulative Remedies.  Neither
the Administrative Agent nor any Lender shall by any act (except by a written
instrument pursuant to Section 8.1), delay, indulgence, omission or otherwise
be deemed to have waived any right or remedy hereunder or to have acquiesced in
any Default or Event of Default.  No failure to exercise, nor any delay in
exercising on the part of the Administrative Agent or any Lender, any right,
power or privilege hereunder shall operate as a waiver thereof.  No single or
partial exercise of any right, power or privilege hereunder shall preclude any
other or further exercise thereof or the exercise of any other right, power or
privilege.  A waiver by the Administrative Agent or any Lender of any right or
remedy hereunder on any one occasion shall not be construed as a bar to any
right or remedy which the Administrative Agent or such Lender would otherwise
have on any future occasion.  The rights and remedies herein provided are
cumulative, may be exercised singly or concurrently and are not exclusive of
any other rights or remedies provided by law.

         8.4     Enforcement Expenses, Indemnification.


                                      32

         (a)     Each Guarantor agrees to pay or reimburse each Lender and the
Administrative Agent for all its costs and expenses incurred in collecting
against such Guarantor under the guaranty contained in Section 2 or otherwise
enforcing or preserving any rights under this Agreement and the other Loan
Documents to which such Guarantor is a party, including, without limitation,
the reasonable fees and disbursements of counsel (including the allocated fees
and expenses of in-house counsel) to each Lender and of counsel to the
Administrative Agent.

         (b)     Each Guarantor agrees to pay, and to save the Administrative
Agent and the Lenders harmless from, any and all liabilities with respect to,
or resulting from any delay in paying, any and all stamp, excise, sales or
other taxes which may be payable or determined to be payable with respect to
any of the Collateral or in connection with any of the transactions
contemplated by this Agreement.

         (c)     Each Guarantor agrees to pay, and to save the Administrative
Agent and the Lenders harmless from any and all liabilities, losses, damages,
penalties, costs and expenses in connection with this Agreement to the extent
the Borrower would be required to do so pursuant to Section 13.2 of the Credit
Agreement.

         (d)     The agreements in this Section 8.4 shall survive repayment of
the Obligations and all other amounts payable under the Credit Agreement and
the other Loan Documents.

         8.5     Binding Arbitration; Waiver of Jury Trial.

         (a)     Binding Arbitration.  Upon demand of any party, whether made
before or after institution of any judicial proceeding, any dispute, claim or
controversy arising out of, connected with or relating to this Agreement
("Disputes"), between or among parties to this Agreement shall be resolved by
binding arbitration as provided herein.  Institution of a judicial proceeding
by a party does not waive the right of that party to demand arbitration
hereunder.  Disputes may include, without limitation, tort claims,
counterclaims, claims brought as class actions, claims arising from Loan
Documents executed in the future, or claims concerning any aspect of the past,
present or future relationships arising out of or connected with this
Agreement.  Arbitration shall be conducted under and governed by the Commercial
Financial Disputes Arbitration Rules (the "Arbitration Rules") of the American
Arbitration Association and Title 9 of the U.S. Code.  All arbitration hearings
shall be conducted in Charlotte, North Carolina.  The expedited procedures set
forth in Rule 51, et seq. of the Arbitration Rules shall be applicable to
claims of less than $1,000,000.  All applicable statutes of limitation shall
apply to any Dispute.  A judgment upon the award may be entered in any court
having jurisdiction.  Notwithstanding anything foregoing to the contrary, any
arbitration proceeding demanded hereunder shall begin within ninety (90) days
after such demand thereof and shall be concluded within one-hundred and twenty
(120) days after such demand.  These time limitations may not be extended
unless a party hereto shows cause for extension and then such extension shall
not exceed a total of sixty (60) days.  The panel from which all arbitrators
are selected shall be comprised of licensed attorneys.  The single arbitrator
selected for expedited procedure shall be a retired judge from the highest
court of general jurisdiction, state or federal, of the state where the hearing
will be conducted.

         (b)     Jury Trial.  TO THE EXTENT PERMITTED BY LAW, THE
ADMINISTRATIVE AGENT, EACH LENDER AND EACH GRANTOR HEREBY ACKNOWLEDGE THAT BY
AGREEING TO BINDING ARBITRATION THEY HAVE IRREVOCABLY WAIVED THEIR RESPECTIVE
RIGHTS TO A JURY TRIAL WITH RESPECT TO ANY ACTION, CLAIM OR OTHER PROCEEDING
ARISING OUT OF ANY DISPUTE IN CONNECTION WITH THIS AGREEMENT, ANY RIGHTS OR
OBLIGATIONS HEREUNDER, OR THE PERFORMANCE OF SUCH RIGHTS AND OBLIGATIONS.

         8.6     Successors and Assigns.  This Agreement shall be binding upon
and inure to the benefit of each Grantor, the Administrative Agent and the
Lenders, all future holders of the Notes, and their respective successors and
assigns; provided that no Grantor may assign, transfer or delegate any of its
rights or obligations under this Agreement without the prior written consent of
each Lender.

         8.7     Set-Off.  Each Grantor hereby irrevocably authorizes the
Administrative Agent and each Lender at any time and from time to time pursuant
to Section 13.3 of the Credit Agreement, without notice to such Grantor or any
other Grantor, any such notice being expressly waived by each Grantor, to
set-off and appropriate and apply any and all deposits (general or special,
time or demand, provisional or final), in any currency, and any other credits,
indebtedness or claims, in any currency, in each case whether direct or
indirect, absolute or contingent, matured or unmatured, at any time held or
owing by the Administrative Agent or such Lender to or for the credit or the
account of such Grantor, or any part thereof in such amounts as the
Administrative Agent or such Lender may elect, against and on account of the
obligations and liabilities of such Grantor to the Administrative Agent or such
Lender hereunder and claims of every nature and description of the
Administrative Agent or such Lender against such Grantor, in any currency,
whether arising hereunder, under the Credit Agreement, any other Loan Document
or otherwise, as the Administrative Agent or such Lender may elect, whether or
not the Administrative Agent or any Lender has made any demand for payment and
although such obligations, liabilities and claims may be contingent or
unmatured. The Administrative Agent and each Lender shall notify such Grantor
promptly of any such set-off and the application made by the Administrative
Agent or such Lender of the proceeds thereof, provided that the failure to give
such notice shall not affect the validity of such set-off and application.  The
rights of the Administrative Agent and each Lender under this Section 8.7 are
in addition to other rights and remedies (including, without limitation, other
rights of set-off) which the Administrative Agent or such Lender may have.

         8.8     Counterparts.  This Agreement may be executed by one or more
of the parties to this Agreement on any number of separate counterparts
(including by telecopy), and all of said counterparts taken together shall be
deemed to constitute one and the same instrument.

         8.9     Severability.  Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

         8.10    Section Headings.  The Section headings used in this Agreement
are for convenience of reference only and are not to affect the construction
hereof or be taken into consideration in the interpretation hereof.

         8.11    Integration.  This Agreement and the other Loan Documents
represent the agreement of the Grantors, the Administrative Agent and the
Lenders with respect to the subject matter hereof and thereof, and there are no
promises, undertakings, representations or warranties by the Administrative
Agent or any Lender relative to subject matter hereof and thereof not expressly
set forth or referred to herein or in the other Loan Documents.

         8.12    GOVERNING LAW.  THIS AGREEMENT UNLESS OTHERWISE SET FORTH
THEREIN, SHALL BE GOVERNED BY, CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE
LAWS OF THE STATE OF NORTH CAROLINA, WITHOUT REFERENCE TO THE CONFLICTS OR
CHOICE OF LAW PRINCIPLES THEREOF.

         8.13    Consent to Jurisdiction. Each Grantor hereby irrevocably
consents to the personal jurisdiction of the state and federal courts located
in Mecklenburg County, North Carolina, in any action, claim or other proceeding
arising out of any dispute in connection with this Agreement, any rights or
obligations hereunder, or the performance of such rights and obligations.  Each
Grantor hereby irrevocably consents to the service of a summons and complaint
and other process in any action, claim or proceeding brought by the
Administrative Agent or any Lender in connection with this Agreement, any
rights or obligations hereunder, or the performance of such rights and
obligations, on behalf of itself or its property, in the manner specified in
Section 8.2.  Nothing in this Section 8.13 shall affect the right of the
Administrative Agent or any Lender to serve legal process in any other manner
permitted by Applicable Law or affect the right of the Administrative Agent or
any Lender to bring any action or proceeding against each Grantor or its
properties in the courts of any other jurisdictions.

         8.14    Acknowledgments.  Each Grantor hereby acknowledges that:

                 (a)      it has been advised by counsel in the negotiation,
         execution  and delivery of this Agreement;

                 (b)      neither the Administrative Agent nor any Lender has
         any fiduciary relationship with or duty to any Grantor arising out of
         or in connection with this Agreement, and the relationship between the
         Grantors, on the one hand, and the Administrative Agent and Lenders,
         on the other hand, in connection herewith is solely that of debtor and
         creditor; and

                 (c)      no joint venture is created hereby or otherwise
         exists by virtue of the transactions contemplated hereby among the
         Lenders or among the Grantors and the Lenders.

         8.15    Additional Grantors.  Each Subsidiary of the Borrower that is
required to become a party to this Agreement pursuant to Section 8.12 of the
Credit Agreement shall become a Grantor and a Guarantor for all purposes of
this Agreement upon execution and delivery by such Subsidiary of a Guaranty and
Collateral Agreement Supplement in the form of Annex I hereto.

         8.16    Releases.

         (a)     At such time as the Loans, the Reimbursement Obligations and
the other Obligations shall have been paid in full, the Commitments have been
terminated and no Letters of Credit shall be outstanding, the Collateral shall
be released from the Liens created hereby, and this Agreement and all
obligations (other than those expressly stated to survive such termination) of
the Administrative Agent and each Grantor hereunder shall terminate, all
without delivery of any instrument or performance of any act by any party, and
all rights to the Collateral shall revert to the Grantors.  At the request and
sole expense of any Grantor following any such termination, the Administrative
Agent shall deliver to such Grantor any Collateral held by the Administrative
Agent hereunder, and execute and deliver to such Grantor such documents as such
Grantor shall reasonably request to evidence such termination.

         (b)     If any of the Collateral shall be sold, transferred or
otherwise disposed of by any Grantor in a transaction permitted by the Credit
Agreement, then the Administrative Agent, at the request and sole expense of
such Grantor, shall execute and deliver to such Grantor all releases or other
documents reasonably necessary or desirable for the release of the Liens
created hereby on such Collateral.  At the request and sole expense of the
Borrower, a Guarantor shall be released from its obligations hereunder in the
event that all the capital stock of such Guarantor shall be sold, transferred
or otherwise disposed of in a transaction permitted by the Credit Agreement;
provided that the Borrower shall have delivered to the Administrative Agent, at
least ten Business Days prior to the date of the proposed release, a written
request for release identifying the relevant Guarantor and the terms of the
sale or other disposition in reasonable detail, including the price thereof and
any expenses in connection therewith, together with a certification by the
Borrower stating that such transaction is in compliance with the Credit
Agreement and the other Loan Documents.

         Re:     Credit Agreement dated as of February 17, 1999 (as amended,
                 restated, supplemented or otherwise modified, the "Credit
                 Agreement"), by and among MINDSPRING ENTERPRISES, INC., a
                 corporation organized under the laws of Delaware, as borrower
                 (the "Borrower"), the Lenders party thereto, FIRST UNION
                 CAPITAL MARKETS CORP., as Arranger, and FIRST UNION NATIONAL
                 BANK, as Administrative Agent (the "Administrative Agent") for
                 such Lenders

Ladies and Gentlemen:

          The company or companies set forth on the signature page hereto
(collectively, the "Company") maintains with us (hereinafter referred to as the
"Bank") the accounts and lockboxes set forth on Schedule I hereto
(collectively, the "Deposit Accounts"), which are all the accounts and
lockboxes of the Company maintained with the Bank.  By its execution hereof,
the Company has confirmed to the Bank that all amounts and other items in the
Deposit Accounts are and shall be deemed proceeds of the Accounts subject to
the lien of the Administrative Agent granted pursuant to the Guaranty and
Collateral Agreement referred to in the Credit Agreement.

         Unless and until an Account Notice (as defined below) is received by
the Bank in accordance with the provisions of this letter, the Company shall
have the right to withdraw and deposit funds, instruments and other items in
the Deposit Accounts by duly authorized signatories in such amounts and with
such frequency as it chooses, and free of any direction by the Administrative
Agent.  The Administrative Agent may, at its sole discretion, terminate the
Company's signing authority and rights to withdraw or transfer funds and other
items from the Deposit Accounts by delivery to the Company and the Bank of a
written notice thereof (an "Account Notice").  Such Account Notice shall be
effective upon receipt by the Bank.

          From and after the date an Account Notice is received by the Bank and
until such Account Notice is withdrawn by the Administrative Agent or the
termination of this letter (i) withdrawals 



<PAGE>   55

from the Deposit Accounts by the Company shall be prohibited and may be made
only by direction of the Administrative Agent by way of wire transfer or
electronic funds transfer to such account or accounts ("Administrative Agent's
Account") as the Administrative Agent shall notify to the Bank, (ii) the Bank
shall use its reasonable efforts to transfer to Administrative Agent's Account
all collected funds in the Deposit Accounts before noon each business day and
(iii) the Company shall have no right to direct any such transfers.

          The Bank agrees that it will not exercise or claim any right of
setoff against, or any security interest or any banker's lien in, the Deposit
Accounts or in monies or items deposited or to be deposited in the Deposit
Accounts.  The parties hereto agree that the Deposit Accounts will be subject
to the exercise of such rights by the Administrative Agent.  The Bank waives
and releases to the Administrative Agent any right or claim which it may have
in any of the funds or other items at any time deposited or to be deposited in
the Deposit Accounts.

         At the end of each statement period, the Bank's regular statement
covering the deposits to and withdrawals from the Deposit Accounts will be sent
to the Company, with a copy to the Administrative Agent.  The Administrative
Agent will have no liability to the Bank or the Company for any costs, fees or
charges under the Bank's usual and customary procedures or under this letter.
All fees and other charges incurred in connection with the Deposit Accounts
will be payable by the Company.

         The Company may not terminate this letter as long as any of the
Company's Obligations (as defined in the Credit Agreement) to the
Administrative Agent or any Lender under the Credit Agreement are outstanding
and unpaid and any Lender has any obligation to make Loans or has other
obligations to the Company, but the Company may thereafter terminate this
letter by notice to the Bank, provided any such termination notice is also
signed by the Administrative Agent.  The Administrative Agent will exercise its
good faith efforts to sign any such termination notice prepared by the Company
within three business days after receipt by the Administrative Agent.  Any
attempt to terminate this letter by the Company without the prior written
consent of the Administrative Agent shall be void.

         By its execution hereof, the Company agrees to be bound by the
provisions of this letter and represents and warrants that it has no other
accounts or lockboxes with the Bank other than the Deposit Accounts, and
covenants and agrees that any lockboxes or accounts opened by the Company with
the Bank after the date hereof will be added to Schedule 1 of this letter and
be subject upon the establishment thereof to the provisions hereof.

                    DESCRIPTION OF SECURED CREDIT FACILITY

SECURED CREDIT FACILITY

       We have a credit agreement, dated as of February 17, 1999, with First
Union National Bank as lender and as administrative agent for the other lenders,
which agreement provides for a $100,000,000 secured revolving credit facility.
The credit facility will mature on February 17, 2002. The credit facility may be
increased at our option to $200,000,000 with the approval of lenders holding at
least 51% of the aggregate unpaid principal amount of the notes thereunder or,
if no such amounts are outstanding, lenders holding at least 51% of the
aggregate commitment of the lenders. We are obligated under the credit agreement
to deliver to the lenders specific consents and related documents in connection
with eleven of our leased properties within 90 days after February 17, 1999. If
we fail to do so, then on the 91st day after February 17, 1999, (1) our option
to increase the commitment to $200,000,000 will terminate, (2) the commitment
will be automatically and permanently reduced to $20,000,000 plus an incremental
amount based upon the extent of our compliance with the requirement concerning
consents and related documents (with the exception that if we do not deliver the
consents and related documents for our Atlanta, Georgia leased property, no
incremental amount will be added to the $20,000,000 amount); and (3) the
applicable margin will be increased between .375% and 1.00% for both Base Rate
borrowings and LIBOR rate borrowings. While at present we do not anticipate
difficulties in obtaining the described consents and related documents by the 
specified deadline, there can be no assurance that we will be able to do so.

       The credit facility is to be used to finance the acquisition of some of
the assets of NETCOM, to finance permitted acquisitions and for working capital
and general corporate requirements. The following summary of the material
provisions of the credit agreement does not purport to be complete and is
subject to, and qualified in its entirety by reference to, the credit
agreement. Some of the capitalized terms used in this description of the credit
facility are defined at the end of this section.

       Amounts drawn under the credit facility will bear interest, at our
option, at either the Base Rate or the reserve adjusted LIBOR rate, plus an
applicable margin. The applicable margin will be an annual rate which will
fluctuate based on 



                                       1
<PAGE>   2

our ratio of total debt to EBITDA and which will be between 0.25% and 1.00% for
Base Rate borrowings and between 1.25% and 2.00% for LIBOR rate borrowings.

       The credit agreement requires us to repay indebtedness outstanding under
the credit facility with the net cash proceeds from all debt issuances, from
some types of sales of our assets and from some types of insurance proceeds. In
addition, the total loan commitment will be reduced by the amount of net cash
proceeds from debt issuances and, to the extent not reinvested in similar
assets or used to finance the repair or replacement of damaged assets, as the
case may be, by the amount of net cash proceeds from some types of asset sales
and from some types of insurance proceeds.

       Our obligations under the credit facility will be guaranteed by all of
our future subsidiaries. Our obligations are secured by a first priority lien on
all of our current and future assets and properties and will be secured by a
first priority pledge of the capital stock of any subsidiary that we organize or
acquire.

       The credit agreement contains negative covenants limiting our ability and
that of our future subsidiaries to:

       -  incur debt; 
       -  guaranty obligations; 
       -  create liens; 
       -  make loans, advances, investments and acquisitions; 
       -  engage in mergers and liquidations; 
       -  sell assets; 
       -  pay dividends and make distributions; 
       -  exchange and issue some types of convertible or redeemable 
          capital stock; 
       -  engage in transactions with affiliates; 
       -  amend subordinated debt; and 
       -  enter into restrictive agreements and change our fiscal year or 
          accounting method. 

In addition, the credit agreement contains affirmative covenants, including 
covenants requiring:

       -  compliance with laws and material contracts; 
       -  maintenance of corporate existence, properties and insurance; 
       -  payment of taxes and all other obligations; 
       -  year 2000 compatibility; and 
       -  the delivery of financial and other information.

       The credit agreement also requires us to comply with specific financial
tests and to maintain specific financial ratios. We must maintain (1) as of
the end of any fiscal quarter, a ratio of EBITDA to interest expense for the
immediately preceding four consecutive fiscal quarters of no less than 3.0:1.0;
(2) a maximum total debt to EBITDA ratio no greater than 3.0:1.0; and (3) a net
worth not less than $175,000,000 plus 50% of net income (to the extent
positive) plus 75% of the net cash proceeds of equity issuances.

       Failure to satisfy any of the financial covenants constitutes an event of
default under the credit facility, notwithstanding our ability to meet our debt
service obligations. The credit agreement also includes other customary events
of default, including, without limitation, cross default to other debt and 



                                       2

material contracts; insolvency or bankruptcy; occurrence of certain ERISA
events; material undischarged judgments and change in control.

       "Base Rate" means the greater of First Union National Bank's prime
lending rate or the overnight federal funds rate plus 0.50%.

       "EBITDA" means, for any period, the sum of the following on a
consolidated basis, without duplication, for MindSpring and our Subsidiaries (as
defined in the credit agreement) in accordance with generally accepted
accounting principles: (A) net income for such period plus (B) the sum of the
following to the extent deducted in determining net income: (1) income and
franchise taxes, (2) interest expense, (3) amortization, depreciation and
other non-cash charges less (C) interest income and any extraordinary gains.
EBITDA will be adjusted in a manner reasonably satisfactory to First Union
National Bank to include on a pro forma basis as of the first day of any
calculation period any acquisition consummated during that period as permitted
by the credit agreement and exclude on a pro forma basis as of the first day
of any calculation any Subsidiary or assets sold during that period as
permitted by the credit agreement.

       "LIBOR" means the rate of interest per annum determined on the basis of
the rate for deposits in dollars in minimum amounts of at least $5,000,000 for a
period equal to the applicable Interest Period (as defined in the credit
agreement) which appears on the Telerate Page 3750 at approximately 11:00 a.m.
(London time) two business days prior to the first day of the applicable
Interest Period. If, for any reason, the rate does not appear on Telerate Page
3750, then "LIBOR" will be determined by First Union National Bank to be the
arithmetic average of the rate per annum at which deposits in dollars would be
offered by first class banks in the London interbank market to First Union
National Bank at approximately 11:00 a.m. (London time) two business days prior
to the first day of the applicable Interest Period for a period equal to that
Interest Period and in an amount substantially equal to the amount of the
applicable loan.
