(1)  BASIS OF PRESENTATION
     ---------------------

        D&E Communications, Inc. is a telecommunications holding company. The
     accompanying consolidated financial statements include the accounts of
     Denver and Ephrata Telephone and Telegraph Company ("D&E Telephone"); D&E
     Holdings, L.P. ("Holdings L.P."); D&E Telephone and Data Systems ("TDS");
     D&E Marketing Corp. ("Marketing"); D&E Wireless, Inc. ("Wireless"); and D&E
     Investments, Inc. ("Investments"). D&E Communications, Inc., including
     these subsidiary companies, is defined and referred to herein as "D&E".

        The accompanying financial statements are unaudited and have been
     prepared by D&E pursuant to generally accepted accounting principles and
     the rules and regulations of the Securities and Exchange Commission
     ("SEC"). In the opinion of management, the financial statements include all
     adjustments (consisting of normal recurring adjustments) necessary to
     present fairly the results of operations, financial position, and cash
     flows of D&E for the periods presented. Certain information and footnote
     disclosures normally included in financial statements prepared in
     accordance with generally accepted accounting principles have been
     condensed or omitted pursuant to such SEC rules and regulations. The use of
     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 amount of revenues and
     expenses during the reporting period. Actual results could differ from
     those estimates. D&E believes that the disclosures made are adequate to
     make the information presented not misleading. These financial statements
     should be read in conjunction with the financial statements and notes
     thereto included in the D&E Annual Report on Form 10-K for the fiscal year
     ended December 31, 1997 and the Form 10-Q's for March 31, 1998 and June 30,
     1998.


(2)  NON-CASH FINANCING AND INVESTING ACTIVITIES
     -------------------------------------------

        D&E recorded non-cash transactions for shares of common stock issued in
     connection with an acquisition and a merger. D&E issued 21,408 shares of
     D&E common stock in January 1997 as the deferred portion of the price in
     connection with the acquisition of Com Tech

     Technical Services, now doing business as D&E Computer Networking Services
     ("Computer Networking "). Separately, $7,307 of the cost incurred in the
     merger with PCS One, Inc. was paid by the issuance of 317,667 shares of D&E
     common stock in March 1997. D&E assumed a long-term note payable to the
     Federal Communications Commission ("FCC") for $11,879 as part of the PCS
     One, Inc. merger during the first quarter of 1997.

        On June 8, 1998, the FCC debt of $11,879 was extinguished along with its
     $1,178 accrued interest by acceptance of the FCC's Amnesty Option. Under
     the terms of the Amnesty Option, the full license spectrum for the
     Lancaster, PA Basic Trading Area ("BTA") C-Block license with a book value
     of $21,417 was returned to the FCC. D&E did not choose the Disaggregation
     Option, which allowed a return of a portion of the spectrum and partial
     reduction of FCC debt, because the Amnesty Option provided the potential
     for a greater long term cash savings. D&E has additional spectrum with
     other licenses available to continue development of the wireless business
     through its D&E/Omnipoint Wireless Joint Venture, L.P. ("PCS ONE"). See
     Note 3.

(3)  ACQUISITIONS AND JOINT VENTURES WITH AFFILIATED COMPANIES
     ---------------------------------------------------------

        On March 21, 1997 D&E merged with PCS One, Inc., the owner of the C-
     Block broadband PCS license to operate in the Lancaster, Pennsylvania
     market. The merger was accounted for as a purchase with no material effect
     from the merger on the consolidated net income in 1997. D&E recorded the
     merger with PCS One, Inc. at a value of $21,123. D&E issued 317,667 shares
     of D&E common stock to PCS One, Inc. shareholders. Long-term debt payable
     to the FCC of $11,879 was assumed, and a note payable to The D and E Group
     of $1,559 was assumed and eliminated in consolidation. D&E dissolved its
     80% owned partnership, The D and E Group, which held a minority interest in
     PCS One, Inc. D&E then formed a subsidiary corporation, Investments, to
     hold the Lancaster C-Block license. D&E formed a separate subsidiary,
     Wireless, in April 1997 to design, construct, and operate the PCS network.

        On November 14, 1997, Wireless and Omnipoint Venture Partner I, L.L.C.
     formed a limited partnership, PCS ONE. Wireless holds a 50% interest in PCS

     Reading, Pennsylvania. Under the terms of the agreement, the joint venture
     will operate for an initial period of 10 years, with provisions for
     subsequent renewals. Wireless recorded $1,703 and $5,074 as its share of
     the PCS ONE loss for the three month and nine month periods ending
     September 30, 1998, respectively.

(4)  DISPOSITION OF BUSINESS
     -----------------------

        On May 14, 1998 Holdings sold its fifteen percent (15%) interest in
     Berks & Reading Area Cellular Enterprises for $2,375. The gain on the sale
     was $1,659. The proceeds from the sale were used by D&E to increase its
     investment in PCS ONE by $1,600 and for working capital requirements. The
     Holdings L.P. partnership was dissolved on June 10, 1998 because it no
     longer owned any cellular investments and its business purpose was
     complete.

(5)  PRIVATE PLACEMENT FINANCING
     ---------------------------

        On January 7, 1998 D&E issued 1.3 million shares of D&E Common Stock to
     a subsidiary of Citizens Utilities Company ("Citizens") in consideration
     for $27 million, or $20.78 per share, pursuant to an exemption from
     registration under Section 4 (2) of the Securities Act of 1933, as amended.
     All such shares are unregistered, but have certain registration rights.
     Under the terms of the agreement, Citizens had certain restrictions, which
     expired on November 3, 1998, relating to future purchases or sales of D&E
     Common Stock. Additionally, in connection with this agreement, D&E issued
     warrants on January 7, 1998 to acquire 65,000 shares of Common Stock at
     $20.78 per share. The warrants are exercisable immediately and at any time
     within five years from the date of grant. All such warrants are
     unregistered, but have certain registration rights for the underlying
     common stock.

(6)  COMPREHENSIVE INCOME
     --------------------

        During 1997, the Financial Accounting Standards Board issued Statement
     of Financial Accounting Standards No. 130, "Reporting Comprehensive Income"
     ("SFAS 130"), which the Company adopted as of January 1, 1998.
     Comprehensive income consists of net income and other gains and losses
     affecting shareholders' equity that, under generally accepted accounting
     principles, are excluded from net income. For D&E, such items have included
     only reductions of the

     ESOP trust loan. Since its adoption by the Company, there have been no
     transactions reportable under SFAS 130.


(7)  RECENT ACCOUNTING PRONOUNCEMENTS
     --------------------------------

        In March 1998, the American Institute of Certified Public Accountants
     (AICPA) issued Statement of Position No. 98-1, "Accounting for the Costs of
     Computer Software Developed or Obtained for Internal Use," (SOP 98-1). SOP
     98-1 provides, among other things, guidance for determining whether
     computer software is for internal use and when the cost related to such
     software should be expensed as incurred or capitalized and amortized. SOP
     98-1 is required to be adopted no later than January 1, 1999.

        D&E subsidiaries currently capitalize central office initial operating
     system and initial application software costs. For noncentral office
     equipment, only the initial operating system software is capitalized.
     Subsequent additions, modifications, or upgrades of initial software
     programs, whether operating or application packages, are expensed as
     incurred. D&E is currently evaluating the provisions of SOP 98-1 and has
     not yet quantified the effect at this time. The adoption of SOP 98-1 is
     expected to result in an increase in earnings in the year of adoption due
     to the prospective capitalization of costs which previously were expensed.

(8)  SUBSEQUENT EVENTS
     -----------------

        On October 22, 1998, D&E announced that its Board of Directors
     authorized the repurchase of up to $2 million worth of its shares of Common
     Stock. The shares reacquired may be used for its incentive compensation
     programs, Employee Stock Purchase Plan, Dividend Reinvestment Plan, and for
     other corporate purposes.

              -------------------------------------------------
                 Financial Condition and Results of Operations
                 ---------------------------------------------


        Monetary amounts presented in the following discussion are rounded to
     the nearest thousand dollars. Certain items in the financial statements for
     the three months and nine months ended September 30, 1997 have been
     reclassified for comparative purposes.

     RESULTS OF OPERATIONS

        Summary.  Operating revenues increased 5.5% for the three months and 
        -------   
     6.4% for the nine months ended September 30, 1998 compared with the same
     periods of 1997. Operating expenses increased 5.9% for the three month and
     12.3% for the nine month periods of 1998 compared to 1997. The result was
     an operating profit of approximately 16% for the third quarter of 1998 and
     1997. Year-to-date operating income decreased to 13.8% in 1998 from 18.3%
     in the preceding year. This decrease is partially related to D&E Telephone
     cost increases and to the TDS decline in system sales. Equity in income of
     affiliates decreased as a result of the sales in September 1997 and May
     1998 of cellular partnership interests which were generating income.
     Additionally, Eurotel's development of a new phone system in Poland and PCS
     ONE's development of a Personal Communication System (PCS) network in south
     central Pennsylvania, created substantial losses in 1998. These losses are
     expected to continue as these businesses develop. The return of the C-Block
     PCS license for the Lancaster, PA BTA, in June 1998, and the related FCC
     debt extinguishment, resulted in the year-to-date extraordinary loss (net
     of tax) of $7,901. This loss did not result in the use of cash and was
     intended to reduce future cash requirements for principal and interest
     payments. Ongoing amortization and interest expenses will decrease
     approximately $340 per quarter as a result of the license return without
     interruption in the development of the PCS network. Earnings per share were
     also negatively affected by an increase in excess of 20% of common shares
     outstanding, primarily from the issuance of 1.3 million shares to Citizens
     in January 1998.

        Operating Revenues.  Total operating revenues for the three months ended
        ------------------                                                      
     September 30, 1998 were $13,240, up 5.5% from the $12,549 recorded for the
     third quarter in 1997. For the nine months ended September 30, 1998,
     operating revenues were $38,678, up 6.4% from $36,349 for the first nine
     months of 1997. Operating revenues are derived primarily from local network
     services revenues, network access services revenues, long distance network
     services revenues, and other communication services revenues. The quarter
     and year-to-

                 Financial Condition and Results of Operations
                 ---------------------------------------------


     date growth resulted primarily from communication service revenue for
     services provided to affiliated companies, notably PCS ONE. Communication
     products sold decreased primarily as a result of lower telephone system
     sales and the completion of a major data communication network during 1997.

        Local network services revenues are generated from providing local
     exchange and local private line services. Local network services revenues
     for the three months ended September 30, 1998 were $2,579, up 5.4% from
     $2,448 in 1997. For the nine months ended September 30, 1998, local network
     services revenues were $7,642, up 8.9% from $7,019 in 1997. The increase
     was primarily due to a revenue neutral rate adjustment made in May of 1997
     which increased the basic area rate while decreasing some other service
     rates. Additionally, an increase of approximately 5% in the number of
     access lines contributed to the quarter and year-to-date increases.

        Network access services revenues are received from D&E Telephone's
     subscribers, from local exchange carriers, interexchange carriers, and
     wireless companies. They use D&E Telephone's local exchange facilities in
     providing interstate and intrastate long distance services to their
     customers and from settlement pools administered by the National Exchange
     Carrier Association, Inc. ("NECA"). Revenues in this category were $4,203
     for the three months ended September 30, 1998, versus $3,978 in 1997. For
     the nine months ended September 30, 1998 these revenues were $12,523 versus
     $12,290 in the same period of the prior year.

        Long distance network services revenues are received from long distance
     calls made by D&E Telephone customers within the Capital (south central)
     Region of Pennsylvania and world-wide long distance calls made by D&E Long
     Distance customers. Revenues in this category for the three months ended
     September 30, 1998 were $1,557, up 4.7% from $1,487 in 1997. For the nine
     months ended September 30, 1998, these revenues were $4,574, up 3.0% from
     $4,441 in 1997. The increase in the quarterly revenue resulted primarily
     from increases in the minutes of use. Revenue increases were moderated by a
     rate decrease which was one of the provisions within the revenue neutral
     rate adjustment made in May of 1997. The same factors affected the nine-
     month comparison.

        Other communication services revenues include equipment rentals,
     repairs, paging, billing and collection services, and consulting

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


     services provided to affiliated companies, primarily PCS ONE. Revenues in
     this category for the three months ended September 30, 1998 were $1,921, up
     from $709 in 1997. For the nine months ended September 30, 1998, these
     revenues were $5,354 up from $2,064 in 1997. The increases were primarily
     attributable to the revenue for services provided to PCS ONE and the two
     European joint ventures.

        Communication products sold revenues are derived primarily from sale and
     installation of telephone and computer network systems. Revenues in this
     category for the three months ended September 30, 1998 were $1,921, down
     32.2% from $2,833 in 1997. For the nine months ended September 30, 1998,
     these revenues were $5,405, down 26.1% from $7,318 in 1997. The quarter and
     year-to-date amounts were down in 1998 as a result of the completion of
     several major installations in 1997 with no similar work in 1998.


        Operating Expenses.  Total operating expenses for the three-month 
        ------------------ 
     period ended September 30, 1998 were $11,125, up 5.9% from $10,508 recorded
     during the same quarter in 1997. For the nine months ended September 30,
     1998, operating expenses were $33,327, up 12.3% from $29,687 in the first
     nine months of 1997. The primary reason for the increases was the costs
     associated with providing services to affiliated companies, notably PCS
     ONE.

        Communication service expenses, including network operations, network
     access, directory advertising, and other communication service costs, were
     $4,109, up 46.0% from $2,814 for the same quarter of 1997. For the nine
     months ended September 30, 1998, expenses in this category were $12,213, up
     53.5% from $7,956 in 1997. The increase was primarily related to additional
     network operations and other communication service costs described below.

        Network operations expenses are incurred in maintaining D&E Telephone's
     switching and transmission facilities, including digital central office
     switching equipment and outside plant cable and trunk facilities. Network
     operations include related employee costs, engineering expense, maintenance
     of land and buildings, testing, general purpose computers, office
     equipment, video conferencing and other materials and supplies. Expenses in
     this category for the three months ended September 30, 1998 were $1,556,
     down 1.9% from $1,586 during the same quarter in 1997. For the nine months
     ended September 30, 1998, these expenses were $4,883, up 15.0% from $4,245
     in the first nine months of 1997. Expenses for the current quarter

     reflected a decline in software expenditures compared to the third quarter
     of 1997. For the nine months these expenses were up primarily due to an
     increase in the number of employees and the expansion of office space and
     equipment purchases to accommodate them. Computer software and equipment
     purchases also contributed to the increase in network operations expense.

        Other communication service costs include the cost of equipment rentals,
     pageboy service, service maintenance agreements, and, primarily, the costs
     incurred to provide consulting services to affiliates. Expenses in this
     category for the three months ended September 30, 1998 were $1,312 up from
     $128 in the same quarter of 1997. For the nine months ended September 30,
     1998, these expenses were $3,529, up from $338 in the first nine months of
     1997. These costs were primarily for services to D&E affiliates including,
     PCS ONE, the two European operations, and D&E SuperNet.

        The cost of communication products sold for the three months ended
     September 30, 1998 was $1,334, down 26.4% from $1,812 in the same quarter
     of 1997. For the nine months ended September 30, 1998, this cost was
     $3,717, down 25.3% from $4,976 in the first nine months of 1997. The
     decreases were primarily related to a lower number of telephone system
     sales in 1998.

        Depreciation expense for the three months ended September 30, 1998 was
     $2,355, up 13.4% from $2,077 in 1997. For the nine months ended September
     30, 1998, depreciation was $7,108, up 15.3% from $6,167 in 1997. The
     majority of the increases were attributable to an increase in telephone
     plant-in-service including primarily, general purpose computers and digital
     electronic switching equipment placed in service late in 1997.
     Additionally, amortization of the PCS licenses acquired during 1997 began
     when they were placed into service in November 1997. PCS license
     amortization decreased after the return of the C-Block license in June
     1998.

        General and administrative services expenses for the three months ended
     September 30, 1998 were $2,446, down 17.7% from $2,972 in 1997. For the
     nine months ended September 30, 1998 these expenses were $7,714, down 4.3%
     from $8,062 in the first nine months of 1997. The decreases in both periods
     were primarily attributable to decreases in planning and development labor
     related to the PCS business. Increased capital stock tax and other
     operating taxes partially offset these reductions.

        Other Income (Expense).  Other income (expense) for the three months 
        ----------------------                                        
     ended September 30, 1998 was a net expense of $3,074, compared with a net
     income of $11,603 in the same quarter of 1997. For the nine months ended
     September 30, 1998, these accounts were a net expense of $6,368 compared
     with a net income of $10,705 in the first nine months of 1997. These
     changes were primarily related to reduced equity in the income of
     affiliates due to the sale of cellular interests in September 1997 and May
     1998. The third quarter of 1997 included a gain of $11,971 on the sale of
     two cellular partnership interests. Also, D&E's share in the losses of PCS
     ONE totaled $1,703 for the quarter and $5,074 for the first nine months of
     1998 with no similar losses in 1997. Future losses are anticipated to
     continue while the PCS ONE business develops. Offsetting these decreases in
     year-to-date earnings was a gain recorded by D&E on the sale of its last
     cellular partnership investment of $1,659 during the second quarter of
     1998.

        D&E's share of losses from its investment in Monor Communications Group
     ("MCG") was $351 for the quarter ended September 30, 1998, up $137 from a
     $214 loss in the third quarter 1997. For the nine months ended September
     30, 1998, D&E's share of MCG's loss was $656, which was $270 less than the
     loss in the first nine months of 1997. MCG's loss was primarily from its
     investment in Monor Telephone ("MTT") in Hungary. These changes resulted
     primarily from fluctuations in the foreign exchange rates between 1998 and
     1997.

        Start-up loss activities of Eurotel's Pilicka Telephone ("PT") in Poland
     was $958 for the quarter ended September 30, 1998, up $925 from a $33 loss
     in the third quarter of 1997. For the nine months ended September 30, 1998,
     D&E's share of Eurotel's loss was $2,011, or $1,928 more than in the first
     nine months of 1997. Third quarter 1998 expenses included an increase in
     interest expense related to an additional $20 million of financing obtained
     by Eurotel during the third quarter of 1998. Losses related to PT are
     anticipated to continue while construction of the telephone system in
     Poland is under way.

        Interest expense for the three months ended September 30, 1998 was $524,
     up $81 from $443 in 1997. For the nine months ended September 30, 1998,
     interest was $1,889, up $257 from $1,632 for the first nine months of 1997.
     For the nine months ended September 30, 1998, interest expense included
     $346 on the PCS license loan from the FCC. In 1997, the license was not in
     use, therefore the

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


     interest on the loan was capitalized. Since the return of the C-Block
     license, that interest expense has been eliminated. Interest expense
     accrued but unpaid when the license was returned, was recorded as a
     reduction in the extraordinary loss on debt extinguishment. Other interest
     decreased as a result of the reduction of debt after the sale of cellular
     interests in the third quarter of 1997, the principal repayment of long-
     term senior debt which began in 1997, and the infusion of cash from the
     sale of shares to Citizens in January 1998 which was used, in part, to
     further reduce debt.


        Income taxes. Income taxes were $332 for the three months ended 
        ------------
     September 30, 1998, down from $5,935 in 1997. For the nine months ended
     September 30, 1998, income taxes were $923, down from $7,434 in the same
     period of 1997. The reduction in income taxes was primarily the result of
     the losses associated with PCS ONE in 1998 which did not exist in 1997.
     Partially offsetting these tax decreases was a tax increase from D&E's
     September 1997 decision to increase its valuation allowance on deferred tax
     assets related to the equity loss in European investments. The valuation
     allowance was provided because realization of tax loss carryforwards is not
     likely.



     FINANCIAL CONDITION

        Liquidity and Capital Resources.  D&E believes that it has adequate 
        ------------------------------- 
     internal and external resources available to meet ongoing operating
     requirements, including expansion and modernization of the network and
     business development. D&E expects that foreseeable capital requirements for
     its existing businesses will be financed primarily through internally
     generated funds, use of its existing cash or temporary investments, and
     additional debt. Additional short or long-term debt or equity financing may
     be needed to fund growth of the PCS ONE network, other new business
     development activities, and to enhance D&E's capital structure.

        D&E's primary source of funds for the nine months ended September 30,
     1998 was from the issuance on January 7, 1998 of 1.3 million shares of
     Common Stock to Citizens in a private placement for $20.78 per share. The
     $26 million received (net of expenses) was used, in

     part, to repay $6 million of bank debt and to increase investments in or
     advances to affiliates. At September 30, 1998, $15 million was invested in
     commercial paper, and $5.9 million was held in cash balances. These cash
     and investment reserves are intended to be used for additional investment
     in PCS ONE and for other general working capital purposes.

        Other cash changes included cash provided by operating activities of
     $8,672. Major changes in funds provided by operating activities include
     funds provided by a decrease in prepaid expenses of $1,889, offset by a use
     of funds from a decrease in accounts payable and advance billings of
     $4,062. A total of $5,829 for capital expenditures was used primarily for
     $3,128 of computers and switching equipment and $1,342 for outside plant
     including poles and cable improvements.


        The cash and cash equivalents balance at September 30, 1998 was $5,862,
     plus $18,000 was available on short-term lines of credit. In addition to
     this cash, $15,000 was invested in high quality short-term commercial
     paper.

        D&E's ratio of total debt to total debt plus capital decreased to 26.6%
     at September 30, 1998 from 44.0% at December 31, 1997. This change resulted
     primarily from the increase in equity from the Citizens investment which
     was partially used to reduce bank debt.

        The investment by Citizens represented 17.5% of the shares of D&E Common
     Stock outstanding. Under the agreement between the parties, Citizens agreed
     for one year, until November 3, 1998, not to acquire additional shares of
     D&E's Common Stock without D&E's consent. If Citizens proposes to sell any
     shares of D&E Common Stock that it owns, then Citizens must first give D&E
     the opportunity to repurchase them. Citizens has the right to require D&E
     to register the Common Stock it acquired for public resale.

        On October 13, 1998, the Pennsylvania Public Utility Commission ("PA
     PUC") launched a Global Telecommunications Settlement Conference ("GTSC")
     aimed at resolving multiple regulatory

     proceedings. Proceedings, relating to access charge reform, funding for
     universal service, and interconnection charges and agreements, are stayed
     until conclusion of the GTSC, slated for January 29, 1999. Meanwhile, D&E
     has entered a settlement petition with the PA PUC to withdraw its revenue
     neutral rate rebalancing request.

        In compliance with state statutes, D&E petitioned on July 31, 1998, for
     an alternative form of regulation pursuant to Chapter 30 of the Public
     Utility Code. The proceeding, which usually carries a mandatory nine month
     statutory deadline for the PA PUC, was extended for an additional sixty
     days to permit voluntary mediation. Regulatory litigation costs for this
     proceeding are shared with eighteen other incumbent local exchange carriers
     (the "Petitioners"). Upon conclusion of this case in June 1999, the
     Petitioners expect to embark on an accelerated network modernization plan
     in exchange for relaxed regulatory oversight.

        During a period of reconsideration and waiver of the C-Block license
     interest, the FCC reviewed the repayment terms for C-Block license note
     agreements. The FCC offered C-Block holders several options as alternatives
     to the original payment terms. Under the terms of the Amnesty Option
     selected, D&E returned the full license spectrum, reducing license cost by
     $21,417. In return, the FCC canceled the principal and accrued interest
     payable on the financed portion of the license cost, reducing liabilities
     by $13,296. The resulting loss is reported as an extraordinary transaction
     of $7,901 net of the related income tax benefit.

        The Year 2000 issue is the result of computer programs written to use
     two digits rather than four to identify the applicable year. Some of D&E's
     programs that have date-sensitive software might recognize a date entry
     using "00" as the year 1900 rather than 2000. D&E has addressed the issue
     by identifying the programs that need to be modified and has completed the
     modifications to essential programs, including the billing system software
     and the accounting data base system. Operating systems in the Company's
     personal computers have been updated, and Year 2000 compliance has been
     confirmed by vendors whose services are critical to D&E's compliance. Other
     software program modifications and testing are nearing completion, and the
     entire program should be finished in the second quarter of 1999. The cost
     of completing the modifications has been immaterial to the current
     operations, and management believes the changes will be completed without
     material impact on its financial condition or interruption to ongoing
     business

     activities.

        PCS ONE completed a $40 million loan agreement with Northern Telecom
     Inc. ("Nortel") to provide additional funds for continued development of
     the PCS network. As an inducement to Nortel to provide the financing, D&E
     became a party to a Capital Contribution Agreement whereby it became
     jointly and severally liable to Nortel to contribute up to a total of $50
     million of equity to PCS ONE in the event of a default. Omnipoint
     Corporation, D&E's joint venture partner in the development of the PCS ONE
     system is also a signatory to the Capital Contribution Agreement with joint
     and several liability.

        On October 22, 1998, D&E announced that its Board of Directors
     authorized the repurchase of up to $2 million worth of its shares of Common
     Stock. The shares reacquired may be used for its incentive compensation
     programs, Employee Stock Purchase Plan, Dividend Reinvestment Plan, and for
     other corporate purposes. Based on this authorization, D&E acquired 30,000
     shares of its Common Stock in a privately negotiated transaction with a
     member of the Voting Trust on October 27, 1998.


     FORWARD-LOOKING STATEMENTS

        This quarterly report contains certain forward-looking statements as to
     Year 2000 remediation and the future performance of D&E and its various
     domestic and international joint venture investments. Actual results may
     differ as a result of factors over which D&E has no control, including, but
     not limited to, regulatory factors, uncertainties and economic fluctuations
     in the domestic and foreign markets in which the companies compete, 
     foreign-currency risks and increased competition in domestic markets due in
     large part to continued deregulation of the telecommunications industry.

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

        D&E does not invest excess funds in derivative financial instruments or
     other market risk sensitive instruments for the purpose of managing its
     foreign currency exchange rate risk or for any other purpose.

                                   THE LOANS
                                   ---------

     Section 2.01  The Advances.
     ------------  ------------ 

     Each Lender severally agrees, on the terms and conditions hereinafter , to
make advances (the "Advances") to the Borrower of up to an aggregate principal
                    --------                                                  
amount not to exceed such Lender's Commitment on any Business Day from the date
hereof until the Commitment Termination Date.

     Each Loan shall be in an amount equal to at least $1,000,000 (or, if less,
the aggregate remaining unused amounts of all Lenders' Commitments) (unless such
Loan is made in order to pay Nortel any amount owing to Nortel or any Affiliate
thereof, in which case there shall be no minimum amount for such Advance) and
shall consist of Advances of the same Type made on the same day by the Lenders
ratably according to their respective Commitments.

     In no event shall the aggregate principal amount of all Advances
outstanding on any date exceed the lesser of:

               (i)  the Maximum Commitments as of such date, and

               (ii) the Borrowing Base as of such date.

     Section 2.02  Making the Advances.
     ------------  ------------------- 

          (a) Except as otherwise provided in (S) 2.02(b), each Loan shall be
                                              -----------                    
     made on notice, given not later than 11:00 A.M. (New York City time) on the
     third Business Day prior to the date of the proposed Loan in the case of a
     Loan consisting of LIBOR Advances or the first Business Day prior to the
     date of the proposed Loan in the case of a Loan consisting of Base Rate
     Advances by the Borrower to the Administrative Agent.  The Administrative
     Agent shall give to each Lender prompt written notice thereof.  Each such
     notice of a Loan (a "Draw Request") shall be delivered in writing by
                          ------------                                   
     telecopy, overnight or regular mail substantially in the form of Exhibit F
                                                                      ---------
     hereto, specifying therein:

               (i)   the requested date of such Loan (which shall be a Business
          Day);

               (ii)  from which tranche of the Credit Facility such Loan is
          requested;

                                     -27-
<PAGE>
 
               (iii) the requested Type of Advances comprising such Loan;
          provided that the Borrower may not request that Advances be LIBOR
          Advances if, after giving effect to such Advances, there would be more
          than three different Interest Periods then in effect;

               (iv)  the requested aggregate principal amount of such Loan; and

               (v)   the account to which the proceeds of such Loan shall be 
          paid. 

Each Draw Request shall be accompanied by:

                    (A) a Borrowing Base Certificate that, among other things,
               shows the Borrowing Base as of the date of such Draw Request;

                    (B) a certificate that shows the Maximum Commitment as of
               the date of such Draw Request and sets forth in reasonable detail
               the calculation of the amount thereof; and

                    (C) such additional documents as may be required by Article
               IX or the Draw Request.

     Each Lender shall, before 12:00 noon (New York City time) on the date of a
scheduled Loan, make available for the account of its Applicable Lending Office
to the Administrative Agent at the Administrative Agent's Account in same-day
funds, such Lender's ratable portion of such Loan.  After the Administrative
Agent's receipt of such funds and upon fulfillment of the applicable conditions
in Articles VIII and IX, the Administrative Agent will wire transfer same-day
funds in the aggregate principal amount of such Loan to such account as the
Borrower shall have specified in its Draw Request.  If the Administrative Agent
shall receive such funds and if such applicable conditions shall be fulfilled
prior to 12:00 A.M. (New York City time) on the date of any proposed Loan, the
Administrative Agent shall commence the wire transfer (or direct its bank to
commence the wire transfer) of such funds to such account by 2:00 P.M. (New York
City time).

          (b) Anything in subsection (a) above to the contrary notwithstanding,
     (i) the Borrower may not select LIBOR Advances for any Loan or if the
     aggregate amount of such Loan is less than $5,000,000 or if the obligation
     of the Lenders to make LIBOR Advances shall then be suspended pursuant to
                                                                              
     (S) 2.05 or 4.01 and (ii) there shall be no more than three Interest
     ----------------                                                    
     Periods for LIBOR Advances at any one time in effect.

          (c) Each Draw Request shall be irrevocable and binding on the
     Borrower.  In the case of any Loan that the related Draw Request specifies
     is to be comprised of LIBOR Advances, the Borrower shall indemnify each
     Lender 
                                     -28-
<PAGE>
 
     against any loss, cost or expense incurred by such Lender as a result of
     any failure to fulfill on or before the date specified in such Draw Request
     for such Loan the applicable conditions in Articles VIII and IX, including
     any loss (including loss of anticipated profits), cost or expense incurred
     by reason of the liquidation or reemployment of deposits or other funds
     acquired by such Lender to fund the Advance to be made by such Lender as
     part of such Loan when such Advance, as a result of such failure, is not
     made on such date.

          (d) Unless the Administrative Agent shall have received notice from a
     Lender prior to the date of any Loan that such Lender will not make
     available to the Administrative Agent such Lender's ratable portion of such
     Loan, the Administrative Agent may assume that such Lender has made such
     portion available to the Administrative Agent on the date of such Loan in
     accordance with subsection (a) of this (S) 2.02 and the Administrative
                                            --------                       
     Agent may, in reliance upon such assumption, make available to the Borrower
     on such date a corresponding amount.  If and to the extent that such Lender
     shall not have so made such ratable portion available to the Administrative
     Agent, such Lender and the Borrower severally agree to repay or pay to the
     Administrative Agent forthwith on demand such corresponding amount together
     with interest thereon, for each day from the date such amount is made
     available to the Borrower until the date such amount is repaid to the
     Administrative Agent, at (i) in the case of the Borrower, the interest rate
     applicable at the time to Advances comprising such Loan and (ii) in the
     case of such Lender, the Federal Funds Rate.  If such Lender shall repay to
     the Administrative Agent such corresponding amount, such amount so repaid
     shall constitute such Lender's Advance as part of such Loan for purposes of
     this Agreement.

          (e) The failure of any Lender to make the Advance to be made by it as
     part of any Loan shall not relieve any other Lender of its obligation, if
     any, hereunder to make its Advance on the date of such Loan, but no Lender
     shall be responsible for the failure of any other Lender to make the
     Advance to be made by such other Lender on the date of any Loan.

          (f) During the period following the occurrence of a Grandparent
     Unmatured Default until such default is either cured, waived, or becomes a
     Grandparent Debt Default, no Advances shall be made under the Credit
     Facility. If Nortel holds more than ***** of the Commitments at such time,
     Advances up to ***** may be made to pay amounts owing Nortel on outstanding
     purchase orders.

          (g) Notwithstanding anything to the contrary contained in this
     Agreement, if and to the extent that Nortel is a Lender under this
     Agreement and all or a portion of the proceeds of an Advance is to be paid
     to Nortel, the Borrower hereby irrevocably agrees that the portion of each
     Loan to be advanced

     discretion of Nortel be effectively disbursed on the date in the Draw
     Request for such disbursement to the Borrower by virtue of a credit in the
     amount of such Loan given to the Borrower under the Volume Purchase
     Agreement.

     Section 2.03  Fees.
     ------------  ---- 

     The Borrower shall pay to the Administrative Agent for the ratable benefit
of the Lenders ***** a commitment fee (the "Commitment Fee") of ***** per annum
                                            --------------     
on the average undrawn balance of the Credit Facility, which accrual will
commence January 1, 1999. The Commitment Fee shall be due quarterly in arrears
commencing March 31, 1999, and continuing on the last day of each June,
September, December and March thereafter through the Commitment Termination
Date. *****

     The Borrower shall also pay the fees set forth in the Administrative
Agent's Letter on the terms and conditions contained therein.

     Section 2.04  Interest.
     ------------  -------- 

          (a) Except as provided in subsection (b) below, the Borrower shall pay
     interest on the unpaid principal amount of each Advance owing to each
     Lender from and including the date of such Advance through but excluding
     the date on which such principal amount shall be paid in full, at the
     following rates per annum:

               (i)  During such periods as such Advance is a Base Rate Advance,
          a rate per annum equal at all times to the sum of (A) the Base Rate in
          effect from time to time, plus (B) the Applicable Margin in effect
          from time to time and applicable to such Advance, payable in arrears
          quarterly on (x) the last day of each March, June, September and
          December and (y) the Maturity Date with respect to such Advance.

               (ii)  During such periods as such Advance is a LIBOR Advance, a
          rate per annum equal at all times during each Interest Period for such
          Advance to the sum of (A) LIBOR for such Interest Period for such
          Advance, plus (B) the Applicable Margin in effect from time to time
          and applicable to such Advance, payable in arrears on (x) the last day
          of such Interest Period if the applicable Interest Period is one, two
          or three months, or the date which is three months after the first day
          of the Interest Period and the last date of the Interest Period if the
          applicable Interest Period is six months, (y) the date on which such
          Advance shall be Converted or

          repaid or prepaid, in whole or in part
          (together with applicable Breakage Costs), and (z) the Maturity Date
          with respect to such Advance.

               (iii) If the Credit Facility is repaid by the Borrower in full
          prior to the first anniversary of the Closing Date and the Commitments
          of the Lenders are terminated, then so long as Nortel is the only
          Lender at the time, Nortel will refund to the Borrower the difference
          between the aggregate interest which would have accrued on the Credit
          Facility, from the Closing Date if the Applicable Margin had been 
          (A) three percent (3%) above LIBOR for LIBOR Loans and (B) two percent
          (2%) over the Base Rate for Base Rate Loans, as applicable.

          (b) Upon occurrence and during the continuance of a Default, the
     Borrower shall pay interest on

               (i)  the unpaid principal amount of each Advance owing to each
          Lender, payable in arrears on the dates referred to in clause 
          (a) above, at a rate per annum equal at all times to the lesser of 
          (I) 4.00% per annum above the rate per annum then required to be paid
          on such Advance pursuant to clause (a) above, and (II) the Maximum
          Lawful Rate, and

               (ii) the amount of any interest, fee or other amount payable
          hereunder that is not paid when due, from the date such amount shall
          be due until such amount shall be paid in full, payable in arrears on
          the date such amount shall be paid in full and on demand, at a rate
          per annum equal at all times to the lesser of (I) 4.00% per annum
          above the rate per annum then required to be paid on Base Rate
          Advances pursuant to clause (a)(i) above and (II) the Maximum Lawful
          Rate.

     Section 2.05  Interest Rate Determination.
     ------------  --------------------------- 

          (a) If, with respect to any LIBOR Advances, the Required Lenders
     notify the Administrative Agent that LIBOR for any Interest Period for such
     Advances will not adequately reflect the cost to such Required Lenders of
     making, funding or maintaining their respective LIBOR Advances for such
     Interest Period, the Administrative Agent shall forthwith so notify the
     Borrower and the Lenders, whereupon:

               (i)  each LIBOR Advance will automatically, on the last day of
          the then-existing Interest Period therefor, Convert into a Base Rate
          Advance, and

               (ii)  the obligation of the Lenders to make, or to Convert
          Advances into, LIBOR Advances shall be suspended immediately,

                                     -31-
<PAGE>
 
     until such time as the Administrative Agent shall notify the Borrower and
     the Lenders that the circumstances causing such suspension no longer exist.

          (b) On the date on which the aggregate unpaid principal amount of all
     LIBOR Advances shall be reduced, by payment or prepayment or otherwise, to
     less than $5,000,000, such Advances shall automatically Convert into Base
     Rate Advances.

          (c) Upon the occurrence and during the continuance of any Default:

               (i)  each LIBOR Advance will automatically, on the last day of
          the then-existing Interest Period therefor, Convert into a Base Rate
          Advance, and

               (ii)  the obligation of the Lenders to make, or to Convert
          Advances into, LIBOR Advances shall be suspended immediately.

          (d) If the Administrative Agent cannot determine LIBOR for any LIBOR
     Advances:

               (i)   the Administrative Agent shall forthwith notify the
          Borrower and the Lenders that the interest rate cannot be determined
          for such LIBOR Advances,

               (ii)   each such Advance will automatically, on the last day of
          the then-existing Interest Period therefor, Convert into a Base Rate
          Advance, and

               (iii)  the obligation of the Lenders to make, or to Convert
          Advances into, LIBOR Advances shall be suspended immediately,  until
          the Administrative Agent shall notify the Borrower and the Lenders
          that the circumstances causing such suspension no longer exist.

provided that,

          (a) any Conversion of LIBOR Advances into Base Rate Advances shall be
     made only on the last day of an Interest Period for such LIBOR Advances,
     and

<PAGE>
 
          (b) the Borrower may not Convert Base Rate Advances into LIBOR
     Advances if, (A) after giving effect to such Conversion, there would be
     more than three Interest Periods in effect or (B) the Advances to be
     Converted would be less than the minimum amount specified in (S) 2.02(b).
                                                                  ----------- 

     Each such notice of a Conversion shall, within the restrictions specified
above, specify (x) the date of such Conversion, and (y) the Advances to be
Converted.  Each notice of Conversion shall be irrevocable and binding on the
Borrower.

     Section 2.07  Payments and Computations.
     ------------  ------------------------- 

          (a) Except as provided in subsection (b) below, the Borrower shall
     make each payment hereunder and under the Notes not later than 11:00 A.M.
     (New York City time) on the day when due in U.S. dollars to the
     Administrative Agent at the Administrative Agent's Account in same-day
     funds.

          (b) The Administrative Agent will, promptly after its receipt of such
     payments, cause to be distributed funds of the kind received relating to
     the payment of principal or interest or usage fees and other amounts
     ratably (other than amounts payable pursuant to (S)(S) 4.02, 4.03 or
                                                     --------------------
     12.04(c)) to the Lenders for the account of their respective Applicable
     --------                                                               
     Lending Offices, and funds of the kind received relating to the payment of
     any other amount payable to any Lender to such Lender for the account of
     its Applicable Lending Office, in each case to be applied in accordance
     with the terms of this Agreement.

     Upon the Administrative Agent's acceptance of an Assignment and Acceptance
and recording of the information contained therein in the Register pursuant to
                                                                              
(S) 12.07(d), from and after the effective date specified in such Assignment and
- ------------                                                                    
Acceptance, the Administrative Agent shall make all payments hereunder and under
the Notes, in respect of the interest assigned thereby to the Lender assignee
thereunder, and the parties to such Assignment and Acceptance shall make all
appropriate adjustments in such payments for periods prior to such effective
date directly between themselves.

          (c) All computations of interest and fees shall be made by the
     Administrative Agent on the basis of a year of 360 days, for the actual
     number of days (including the first day but excluding the last day)
     occurring in the period for which such interest or fees are payable.  Each
     determination by the Administrative Agent of an interest rate hereunder
     shall be conclusive and binding for all purposes, absent manifest error.

          (d) Whenever any payment hereunder or under the Notes shall be stated
     to be due on a day other than a Business Day, such payment shall be made on
     the next-succeeding Business Day, and such extension of time shall in such
     case be included in the computation of payment of interest or usage fee, as
     the 

                                     -33- 
<PAGE>
 
     case may be; provided that, if such extension would cause payment of
                  --------                                               
     interest on or principal of LIBOR Advances to be made in the next-following
     calendar month, such payment shall be made on the next-preceding Business
     Day.

          (e) Unless the Administrative Agent shall have received notice from
     the Borrower prior to the date on which any payment is due and owing to the
     Lenders hereunder that the Borrower will not make such payment in full, the
     Administrative Agent may assume that the Borrower has made such payment in
     full to the Administrative Agent on such date and the Administrative Agent
     may, in reliance upon such assumption, cause to be distributed to each
     Lender on such due date an amount equal to the amount then due such Lender.
     If and to the extent the Borrower shall not have so made such payment in
     full to the Administrative Agent, each Lender shall repay to the
     Administrative Agent forthwith on demand such amount distributed to such
     Lender together with interest thereon, for each day from the date such
     amount is distributed to such Lender until the date such Lender repays such
     amount to the Administrative Agent, at the Federal Funds Rate.

          (f) To the extent permitted by law, all payments by the Borrower
     hereunder and under any of the other Loan Documents shall be made without
     setoff or counterclaim.  Without limitation of the preceding sentence, to
     the extent permitted by law, the Borrower's obligation to pay all amounts
     due under the Loans shall not be affected by any circumstance whatsoever,
     including:

               (i) any set-off, counterclaim, recoupment, deduction, abatement,
          suspension, diminution, reduction, defense or other right which the
          Borrower may have for any reason whatsoever, including any failure of
          the Collateral or any assets making up the Network, or any part
          thereof, or any representation or service of any supplier,
          manufacturer, installer or distributor, including Nortel;

     applicable Breakage Costs and accrued and unpaid interest on the principal
     amount of the Advances then being prepaid or repaid.  A certificate of any
     Lender setting forth the amount of any Breakage Costs which such Lender is
     entitled to receive shall be furnished to the Borrower relating to any
     prepayment for which the Administrative Agent has received notice in
     accordance with the terms hereof, and shall be presumptively correct absent
     manifest error.  The Borrower shall pay all Breakage Costs to the
     Administrative Agent as in the Lender's certificate pursuant to this

         ILLEGALITY, INCREASED COSTS, CAPITAL ADEQUACY AND INDEMNITIES
         -------------------------------------------------------------

     Section 4.01  Illegality.  Notwithstanding any other provisions herein, if
     ------------  ----------                                                  
any present or future law, regulation, treaty or directive or the interpretation
or application thereof shall make it unlawful for any Lender to make or maintain
LIBOR Loans, such Lender shall forthwith give notice of such circumstances to
the Borrower, the Administrative Agent and the other Lenders and thereupon

          (a) the Commitments of such Lender to make LIBOR Loans shall forthwith
     be suspended until such notifying Lender shall have notified the
     Administrative Agent and the Borrower that the circumstance giving rise to
     such determination no longer exists (and if such notifying Lender shall
     determine that such circumstance no longer exists it shall so notify the
     Administrative Agent and the Borrower promptly after determining the same),
     and

          (b) the aggregate principal amount of such Lender's LIBOR Loans, if
     any, shall be Converted automatically to Base Rate Loans on the last day of
     each

     Interest Period applicable to such LIBOR Loans or within such earlier
     period as may be required by applicable law.

     Such Lender will designate a different Applicable Lending Office if such
designation will avoid the need for any suspension or Conversions described in
the preceding sentence and will not, in the judgment of such Lender, be
otherwise disadvantageous to such Lender.

     Section 4.02  Additional Costs and Capital Adequacy.
     ------------  ------------------------------------- 

          (a) If any present or future applicable law, which expression, as used
     herein, includes statutes, rules and regulations thereunder and
     interpretations thereof by any competent court having jurisdiction with
     respect thereto or by any governmental or other regulatory body or official
     charged with the administration or the interpretation thereof and requests,
     directives, instructions and notices at any time or from time to time
     hereafter made upon or otherwise issued to any Lender or the Administrative
     Agent by any central bank or other fiscal, monetary or other authority
     (whether or not having the force of law), shall

               (i)  impose or increase or render applicable (other than to the
          extent specifically provided for elsewhere in this Agreement) any
          special-deposit, reserve, assessment, liquidity, capital adequacy or
          other similar requirements (whether or not having the force of law)
          against assets held by, or deposits in or for the account of, or loans
          by, or commitments of an office of any Lender, or

               (ii)  impose on any Lender or the Administrative Agent any other
          conditions or requirements with respect to this Agreement, the other
          Loan Documents, such Lender's Commitments, or any class of loans, or
          commitments of which any of the Loans or such Lender's Commitments
          form a part,

and the result of any of the foregoing is to increase the cost to such Lender of
making, funding, issuing, renewing, extending or maintaining any of the Advances
or such Lender's Commitments (taking into account such Lender's then-existing
policies with respect to maintaining capital), then the Borrower shall pay to
the Administrative Agent for the account of such Lender, within 15 days after
demand from time to time as specified by such Lender, additional amounts
sufficient to compensate such Lender or such corporation in the light of such
circumstances, for such increased costs.

          (b) If any law, governmental rule, regulation, policy, guideline or
     directive (whether or not having the force of law) or the interpretation
     thereof by a court or governmental authority with appropriate jurisdiction,
     that in any case becomes effective after the date hereof, affects the
     amount of capital required or 
                                     -42-
<PAGE>
 
     expected to be maintained by any Lender or any corporation controlling such
     Lender and such Lender determines that the amount of capital required to be
     maintained by it is increased by or based upon the existence of such
     Lender's commitment with respect to any Advances, the Borrower will pay to
     such Lender, within 15 days after demand from time to time as specified by
     such Lender, additional amounts sufficient to compensate such Lender or
     such corporation in the light of such circumstances, to the extent that
     such Lender reasonably determines such increase in capital to be allocable
     to the existence of such Lender's commitment to lend hereunder.

          (c) Each demand by a Lender pursuant to this (S) 4.02 shall be
                                                       --------         
     accompanied by a statement setting forth in reasonable detail the basis for
     such demand and the computation of such amount, including any method by
     which such cost was allocated to the Borrower.  In determining the amount
     of any compensation, such Lender may use any reasonable averaging or
     attribution methods  in such demand, and any such methods so used shall be
     binding on the Borrower.  The amount specified in any such demand shall be
     conclusive evidence of the amount owing, absent manifest error.  Such
     Lender will designate a different Applicable Lending Office if such
     designation will avoid the need for or reduce the amount of any
     compensation under this (S) 4.02 and will not, in the judgment of such
                             --------                                      
     Lender, be otherwise disadvantageous to such Lender.  By making any payment
     under this (S) 4.02, the Borrower is not waiving its right to contest that
                --------                                                       
     the amounts  in the certificates are based on manifest error.

     Section 4.03  Taxes.
     ------------  ----- 

          (a) Any and all payments by the Borrower hereunder or under the Notes
     shall be made free and clear of and without deduction for any and all
     present or future taxes, levies, imposts, deductions, charges or
     withholdings, and all liabilities with respect thereto, excluding, in the
                                                             ---------        
     case of each Lender and the Administrative Agent, taxes imposed on its
     income, and franchise taxes imposed on it in lieu of income taxes, by the
     jurisdiction under the laws of which such Lender or the Administrative
     Agent (as the case may be) is organized or any political subdivision
     thereof and, in the case of each Lender, taxes imposed on its income, and
     franchise taxes imposed on it in lieu of income taxes, by the jurisdiction
     of such Lender's Applicable Lending Office or any political subdivision
     thereof (all such non-excluded taxes, levies, imposts, deductions, charges,
     withholdings and liabilities being hereinafter referred to as "Taxes").  If
                                                                    -----       
     the Borrower shall be required by law to deduct any Taxes from or in
     respect of any sum payable hereunder or under any Note to any Lender or the
     Administrative Agent,

               (i)   the sum payable shall be increased as may be necessary so
          that after making all required deductions (including deductions
          applicable 
                                     -43-
<PAGE>
 
          to additional sums payable under this (S) 4.03) such Lender
                                                --------             
          or the Administrative Agent (as the case may be) receives an amount
          equal to the sum it would have received had no such deductions been
          made,

               (ii)  the Borrower shall make such deductions, and

               (iii) the Borrower shall pay the full amount deducted to the
          relevant taxation authority or other authority in accordance with
          applicable law.

          (b) In addition, the Borrower agrees to pay any present or future
     stamp or documentary taxes or any other excise or property taxes, charges
     or similar levies that arise from any payment made hereunder or under the
     Notes or from the execution, delivery or registration of, or otherwise with
     respect to, this Agreement or the Notes (hereinafter referred to as "Other
                                                                          -----
     Taxes").
     -----   

          (c) The Borrower will indemnify each Lender and the Administrative
     Agent for the full amount of Taxes or Other Taxes (including any Taxes or
     Other Taxes imposed by any jurisdiction on amounts payable under this 
     (S) 4.03) paid by such Lender or the Administrative Agent (as the case 
     --------- 
     may be) and any liability (including penalties, interest and expenses)
     arising therefrom or with respect thereto. This indemnification shall be
     made within 15 days from the date such Lender or such Agent (as the case
     may be) makes written demand therefor.

          (d) Within 30 days after the date of any payment of Taxes, the
     Borrower will furnish to the Administrative Agent, at its address referred
     to in (S) 12.02, the original or a certified copy of a receipt evidencing
           ---------                                                          
     payment thereof.  In the case of any payment hereunder or under the Notes
     by or on behalf of the Borrower through an account or branch outside the
     United States or on behalf of the Borrower by a payor that is not a United
     States person, if the Borrower determines that no Taxes are payable in
     respect thereof, the Borrower shall furnish, or shall cause such payor to
     furnish, to the Administrative Agent, at such address, an opinion of
     counsel acceptable to the Administrative Agent stating that such payment is
     exempt from Taxes.  For purposes of this subsection (d) and subsection (e)
     below, the terms "United States" and "United States person" shall have the
                       -------------       --------------------                
     meanings specified in (S) 7701 of the Internal Revenue Code.
                           --------                              

          (e) Each Lender organized under the laws of a jurisdiction outside the
     United States, on or prior to the date of its execution and delivery of
     this Agreement in the case of each initial Lender and on the date of the
     Assignment and Acceptance pursuant to which it becomes a Lender in the case
     of each other Lender, and from time to time thereafter if requested in
     writing by the Borrower (but only so long as such Lender remains lawfully
     able to do so), shall provide the Borrower with Internal Revenue Service
     Form 1001 or 4224, as appropriate, 

                                     -44-
<PAGE>
 
     or any successor or other form prescribed by the Internal Revenue Service,
     certifying that such Lender is exempt from or entitled to a reduced rate of
     United States withholding tax on payments of interest pursuant to this
     Agreement or the Notes. If the form provided by a Lender at the time such
     Lender first becomes a party to this Agreement indicates a United States
     interest withholding tax rate in excess of zero, withholding tax at such
     rate shall be considered excluded from "Taxes" as defined in (S) 4.03(a).
                                             -----                -----------
     If any form or document referred to in this subsection (e) requires the 
     disclosure of information, other than information necessary to compute the
     tax payable and information required on the date hereof by Internal Revenue
     Service form 1001 or 4224, that the Lender reasonably considers to be
     confidential, the Lender shall give notice thereof to the Borrower and
     shall not be obligated to include in such form or document such
     confidential information.

          (f) For any period with respect to which a Lender has failed to
     provide the Borrower with the appropriate form described in (S) 4.03(e)
                                                                 -----------
     (other than if such failure is due to a change in law occurring subsequent
     ------ ----                                                               
     to the date on which a form originally was required to be provided, or if
     such form otherwise is not required under the first sentence of subsection
     (e) above), such Lender shall not be entitled to indemnification under 
     (S)4.03(a) or (c) only with respect to those Taxes which would not have 
     ----------    ---    
     been imposed by the United States; provided that should a Lender become  
                                        --------                              
     subject to Taxes because of its failure to deliver a form required
     hereunder, the Borrower shall take such steps as such Lender shall
     reasonably request and at such Lender's expense to assist such Lender to
     recover such Taxes.

          (g) If the Borrower is required to pay any amounts to or for the
     account of any Lender pursuant to this (S) 4.03, such Lender will designate
                                            --------                            
     a different Applicable Lending Office if such designation will avoid the
     need for or reduce the amount of any such payment and will not, in the
     judgment of such Lender, be otherwise disadvantageous to such Lender.

     Section 4.04  Survival.   Without prejudice to the survival of any other
     ------------  --------                                                  
agreement of the Borrower hereunder, the agreements and obligations of the
Borrower contained in this Article IV shall survive the payment in full of
principal and interest hereunder and under the Notes.

               (ii)  The Administrative Agent shall have received on or before

     Borrowing Base Certificate executed by an authorized officer of the
     Borrower.

     monies;

     Section 11.01  Authorization and Action.  Each Lender appoints and 
     -------------  ------------------------                            
authorizes the Administrative Agent to take such action as agent on its behalf
and to exercise such powers and discretion under this Agreement and the other
Loan Documents as are delegated to the Administrative Agent by the terms hereof
and thereof, together with such powers and discretion as are reasonably
incidental thereto. As to any matters not expressly provided for by the Loan
Documents (including enforcement or collection of the Notes), the Administrative
Agent shall not be required to exercise any discretion or take any action, but
shall be required to act or to refrain from acting (and shall be fully protected
in so acting or refraining from acting) upon the instructions of the Required
Lenders, and such instructions shall be binding upon all Lenders; provided that
                                                                  --------    
the Administrative Agent shall not be required to take any action that exposes
the Administrative Agent to personal liability or that is contrary to this
Agreement or applicable law. The Administrative Agent will give to each Lender
prompt notice of each notice given to it by the Borrower pursuant to the terms
of this Agreement.

Administrative Agent nor any of its directors, officers, agents or employees
shall be liable for any action taken or omitted to be taken by it or them under
or in connection with the Loan Documents, except for its or their own gross
negligence or willful misconduct.  Without limitation of the generality of the
foregoing, the Administrative Agent:

          (a) may treat the Lender that made any Advance as the holder of the
     Indebtedness resulting therefrom until the Administrative Agent receives
     and accepts an Assignment and Acceptance entered into by such Lender, as
     assignor, and an assignee, as provided in (S) 12.07;

          (b) may consult with legal counsel (including counsel for any Loan
     Party), independent public accountants and other experts selected by it and

     faith by it in accordance with the advice of such counsel, accountants or

     responsible to any Lender for any statements, warranties or representations
     (whether written or oral) made in or in connection with the Loan Documents;

          (d) shall not have any duty to ascertain or to inquire as to the
     performance or observance of any of the terms, covenants or conditions of
     any Loan Document on the part of any Loan Party or to inspect the property
     (including the books and records) of any Loan Party;

          (e) shall not be responsible to any Lender for the due execution,
     legality, validity, enforceability, genuineness, sufficiency or value of,
     or the perfection or priority of any lien or security interest created or
     purported to be created under or in connection with, any Loan Document or
     any other instrument or document furnished pursuant thereto;

          (f) shall incur no liability under or in respect of any Loan Document
     by acting upon any notice, consent, certificate or other instrument or
     writing (which may be by telegram, telecopy, cable or telex) believed by it
     to be genuine and signed or sent by the proper party or parties; and

          (g) shall incur no liability as a result of any determination whether
     the transactions contemplated by the Loan Documents constitute a "highly
                                                                       ------

     the Comptroller of the Currency, the Federal Deposit Insurance Corporation
     and the Board of Governors of the Federal Reserve System.

     Section 11.03  Nortel and Affiliates.  With respect to its Commitments, the
     -------------  ---------------------                                       
Advances made by it and the Note issued to it, Nortel and any other
Administrative Agent in its individual capacity shall have the same rights and
powers under the Loan Documents as any other Lender and may exercise the same as
though it were not the Administrative Agent; and the term "Lender" or "Lenders"
                                                           ------      ------- 
shall, unless otherwise expressly indicated, include Nortel in its individual
capacity or any other Administrative Agent in its individual capacity.  Nortel
or any other Administrative Agent in its individual capacity and its affiliates
may generally engage in any kind of business with the Borrower and any of its
Affiliates and any Person who may do business with or own securities of the
Borrower or any of its Affiliates, all as if Nortel or any other Administrative
Agent in its individual capacity were not the Administrative Agent and without
any duty to account therefor to the Lenders.

     Section 11.04  Lender Credit Decision.  Each Lender acknowledges 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 credit analysis and decision to enter into this
Agreement. Each Lender also acknowledges 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 decisions in taking or not taking action under this
Agreement.

     Section 11.05  Indemnification.  Each Lender severally will indemnify the
     -------------  ---------------                                           
Administrative Agent (to the extent not promptly reimbursed by the Borrower)
from and against such Lender's ratable share of any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever that may be imposed
on, incurred by, or asserted against the Administrative Agent in any way
relating to or arising out of the Loan Documents or any action taken or omitted
by the Administrative Agent under the Loan Documents; provided that no Lender
                                                      --------               
shall be liable for any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
resulting from the Administrative Agent's gross negligence or willful
misconduct. Without limitation of the foregoing, each Lender will reimburse the
Administrative Agent promptly upon demand for its ratable share of any costs and
expenses payable by the Borrower under (S) 12.04, to the extent that the
                                       ---------                        
Administrative Agent is not promptly reimbursed for such costs and expenses by
the Borrower.  It is the express intent of the parties that the Administrative
Agent shall be indemnified hereunder for all negligent acts or omissions other
than those resulting from the Administrative Agent's gross negligence or willful
misconduct.  For purposes of this (S) 11.05, the Lenders' respective ratable
                                  ---------                                 
shares of any amount shall be determined, at any time, according to the sum of
(a) the aggregate principal amount of the Advances outstanding at such time and
owing to the respective Lenders and (b) the aggregate unused portions of their
respective Commitments.  The failure of any Lender to reimburse the
Administrative Agent promptly upon demand for its ratable share of any amount
required to be paid by the Lenders to the Administrative Agent as provided
herein shall not relieve any other Lender of its obligation hereunder to
reimburse the Administrative Agent for its ratable share of such amount, but no
Lender shall be responsible for the failure of any other Lender to reimburse the
Administrative Agent for such other Lender's ratable share of such amount.
Without prejudice to the survival of any other agreement of any Lender
hereunder, the agreements and obligations of each Lender contained in this (S)
                                                                           ---

amounts payable hereunder and under the other Loan Documents.

     Section 11.06  Successor Administrative Agents.  The Administrative Agent
     -------------  -------------------------------                           
may resign at any time by giving written notice thereof to the Lenders. Upon any
such resignation, the Required Lenders shall have the right to appoint a
successor Administrative Agent. If no successor Administrative Agent shall have
been so 

                                     -110-

appointed by the Required Lenders, and shall have accepted such appointment, 
within 30 days after the retiring Administrative Agent's giving of notice 
of resignation, then the retiring Administrative Agent may, on behalf of
the Lenders, appoint a successor Administrative Agent, which shall be a
commercial bank organized under the laws of the United States or of any State
thereof and having a combined capital and surplus of at least $500,000,000. Upon
the acceptance of any appointment as Administrative Agent hereunder by a
successor Administrative Agent and upon the execution and filing or recording of
such financing statements, or amendments thereto, and such other instruments or
notices, as may be necessary or desirable, or as the Required Lenders may
request, in order to continue the perfection of the Liens granted or purported
to be granted by the Collateral Documents, such successor Administrative Agent
shall succeed to and become vested with all the rights, powers, discretion,
privileges and duties of the retiring Administrative Agent, and the retiring
Administrative Agent shall be discharged from its duties and obligations under
the Loan Documents. After any retiring Administrative Agent's resignation
hereunder, the provisions of this Article XI shall inure to its benefit as to
any actions taken or omitted to be taken by it while it was Administrative Agent
under this Agreement. A successor Administrative Agent will notify the Borrower
of its appointment promptly after its appointment.

          (but excluding legal fees).

               (iii) The Borrower shall also pay on demand:

                    (A) so long as Nortel has assigned any Loans or Commitments
               or has granted a participation in a portion of its Loans or
               Commitments under the Credit Facility, all ongoing costs,
               including, without limitation, all reasonable legal fees and

               any action, suit or litigation, any bankruptcy, insolvency or
               other similar proceeding affecting creditors' rights generally or
               otherwise, (2) the perfection, protection or preservation of any
               of their respective rights or interests under the Loan Documents
               or to or in the Collateral, (3) the administration of this
               Agreement or any other Loan Document and (4) any amendments,

                    (B) all reasonable legal fees and expenses relating to the
               matters described in clause (A) above incurred by Nortel as
               Administrative Agent or a Lender if a Default shall have occurred
               and be continuing under this Agreement; and

                    (C) all reasonable legal fees and expenses relating to the
               matters described in clause (A) above incurred by any Lender

               Lender would have an indemnification obligation (whether or not
               contingent on non-payment thereof by the Borrower) under this
               Agreement.

          (b) If, at any time, Breakage Costs are due and owing hereunder, the
     Borrower shall, upon demand by the Lender to whom such Breakage Costs are
     due (with a copy of such demand to the Administrative Agent), pay to the
     Administrative Agent for the account of such Lender any such Breakage
     Costs.

          (c) If the Borrower fails to pay when due any costs, expenses or other
     amounts payable by it under any Loan Document, including fees and expenses
     of counsel and indemnities, such amount may be paid on behalf of the
     Borrower by the Administrative Agent or any Lender, in its sole discretion.

          (d) The Borrower will indemnify each Lender, the Administrative Agent
     and their respective affiliates and their officers, directors, employees,
     agents and advisors (each, an "Indemnified Party") and hold each
                                    -----------------                
     Indemnified Party harmless from and against any and all claims, damages,
     losses, liabilities and expenses (including reasonable fees and expenses of
     counsel) that may be incurred by or asserted or awarded against any
     Indemnified Party, in each case arising out of or in connection with

               (i)   the Notes, this Agreement and other Loan Documents, any of
          the transactions contemplated herein or therein or the actual or
          proposed use of the proceeds of the Advances, or

               (ii)  the actual or alleged presence of Materials of
          Environmental Concern on any property of the Borrower or any
          environmental proceeding relating in any way to the Borrower,

except to the extent such claim, damage, loss, liability or expense is found in
a final, non-appealable judgment by a court of competent jurisdiction to have
resulted from such Indemnified Party's gross negligence or willful misconduct.
In the case of any investigation, litigation or other proceeding to which the
indemnity in this (S) 12.04(d) applies, the indemnity shall be effective whether
                  ------------                                                  
or not such investigation, litigation or proceeding is brought by the Borrower,
its directors, shareholders or creditors or an Indemnified Party or any other
Person or any Indemnified Party is otherwise a party thereto and whether or not
the transactions contemplated hereby are consummated.  The Borrower also shall
not assert any claim against the Administrative Agent, any Lender, any of their
Affiliates, or any of their respective directors, officers, employees, attorneys
and agents, on any theory of liability, for special, indirect, consequential or
punitive damages arising out of or otherwise relating to the Notes, this
Agreement, any of the transactions contemplated herein or the actual or proposed
use of the proceeds of the Advances.

          (e) Without prejudice to the survival of any other agreement of the
     Borrower hereunder, the agreements and obligations of the Borrower
     contained in this (S) 12.04 shall survive the payment in full of principal
                       ---------

     Section 12.05  Right of Set-off.  Upon the occurrence and during the
     -------------  ----------------                                     
continuance of any Event of Default, each Lender and each of its Affiliates is
authorized at any time and from time to time, to the fullest extent permitted by
law, to set off and otherwise apply any and all deposits (general or special,
time or demand, provisional or final) at any time held and other indebtedness at
any time owing by such Lender or such Affiliate to or for the credit or the
account of the Borrower against any and all of the obligations of the Borrower
now or hereafter existing under this Agreement and the Note or Notes held by
such Lender, irrespective of whether such Lender shall have made any demand
under this Agreement or such Note and although such obligations may be
unmatured.  Each Lender agrees promptly to notify the Borrower after any such
set-off and application; provided that the failure to give such notice shall not
                         --------                                               
affect the validity of such set-off and application.  The rights of each Lender
and its Affiliates under this (S) 12.05 are in addition to other rights and
                              ---------                                    
remedies (including other rights of set-off) that such Lender and its Affiliates
may have.

     Section 12.06  Binding Effect.  This Agreement shall become effective when
     -------------  --------------                                         
it shall have been executed by the Borrower and the Administrative Agent and
when the Administrative Agent shall have been notified by each Lender that such
Lender has executed it and thereafter shall be binding upon and inure to the
benefit of the Borrower, the Administrative Agent, each Lender and their
respective successors and assigns, except that the Borrower shall not have the
right to assign its rights hereunder or any interest herein without the prior
written consent of the Lenders.

     Section 12.07  Assignments and Participations.
     -------------  ------------------------------ 

          (a) Each Lender may assign to one or more banks or other entities
     (including any trust or other Person in connection with a securitization or
     monetization of the Advances or other indirect raising of capital) all or a

                                    --------        
     shall be conclusive and binding for all purposes, absent 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

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
substantially in the form of Exhibit A.
                             ---------

     it); provided that

               (i)    such Lender's obligations under this Agreement (including
          its Commitments) shall remain unchanged,

     or proposed assignment or participation pursuant to this (S) 12.07,
                                                              --------- 
     disclose to the assignee or participant or proposed assignee or
     participant, any information relating to the Borrower furnished to such
     Lender by or on behalf of the Borrower; provided that, prior to any such
                                             --------                        
     disclosure, the assignee or participant or proposed assignee or participant
     shall agree to preserve the confidentiality of any Confidential Information
     received by it from such Lender.

          (g) Notwithstanding any other provision  in this Agreement, any Lender
     may at any time create a security interest in all or any portion of its
     rights under this Agreement (including the Advances owing to it and the
     Note or Notes held by it) in favor of any Federal Reserve Bank in
     accordance with Regulation A of the Board of Governors of the Federal
     Reserve System.

          (h) The Borrower shall maintain, or cause to be maintained, a register
     (the "Registered Note Register") (which, at the request of the Borrower,
           ------------------------

     extra charge to the Borrower at the address to which notices to the
     Administrative Agent are to be send hereunder) on which it enters the name
     of the registered owner of each of the Loans evidenced by a Registered
     Note.  Notwithstanding anything to the contrary contained in this
                                                                      
     (S)12.07(h), a Registered Note and the Loans evidenced thereby may be

     assigned or otherwise transferred in whole or in part only by registration
     of such assignment or transfer of such Registered Note and the Loans
     evidenced thereby on the Registered Note Register (and each Registered Note
     shall expressly so provide).  Any assignment or transfer of all or part of
     such Loans and the Registered Note evidencing the same shall be registered
     on the Registered Note Register only upon surrender for registration of
     assignment or transfer of the Registered Note evidencing such Loans, duly
     endorsed by (or accompanied by a written instrument of assignment or
     transfer duly executed by) the registered noteholder thereof, and thereupon
     one or more new Registered Notes in the same aggregate principal amount
     shall be issued to the designated assignee(s) or transferee(s).  Prior to
     the due presentment for registration of transfer of any Registered Note,
     the Borrower and the Administrative Agent shall treat the Person in whose
     name such Loans and the Registered Note(s) evidencing the same are
     registered as the owner thereof for the purpose of receiving all payments
     thereon and for all other purposes, notwithstanding any notice to the
     contrary.  The Registered Note Register shall be available for inspection
     by the Borrower and any Lender at any reasonable time upon reasonable prior
     notice.

and all of which taken together shall constitute one and the same agreement.

     Section 12.10  Confidentiality.  Neither the Administrative Agent nor any
     -------------  ---------------                                           
Lender shall disclose any Confidential Information to any Person without the
consent of the Borrower, other than

          (a) to the Administrative Agent's or such Lender's Affiliates and
     their officers, directors, employees, agents and advisors and to actual or
     prospective assignees and participants, and then only on a confidential
     basis,

          (b) as required by any law, rule or regulation or judicial process,
     and

          (c) as requested or required by any state, federal or foreign
     authority or examiner regulating banks or banking.

     The Administrative Agent and the Lenders shall not, and the Borrower shall

of this Agreement, the other Loan Documents or the transactions contemplated

          case to the extent that the Administrative Agent, any Lender or the
          Borrower deems necessary or appropriate,

               (iii) as required by any law, rule or regulation or judicial
          process, and

               (iv)  as requested by any state, federal or foreign regulatory
          authority.

A reasonable period of time prior to making any disclosure with respect to such
terms and transactions that is permitted under clause (iv) or (v) of the
preceding sentence, the 

                                     -125-
<PAGE>
 
party proposing, or whose Affiliate is proposing, to make such disclosure will
consult with the other party concerning the need for and scope of any such
disclosure.

     Section 12.11  Consent to Jurisdiction.  The Borrower irrevocably:
     -------------  -----------------------

     sitting in New York City in any action or proceeding arising out of or
     relating to any Loan Document;

          (b) agrees that all claims in respect of such action or proceeding may
     be heard and determined in such New York state or federal court;

          (c) waives, to the fullest extent that it may effectively do so, the
     defense of an inconvenient forum to the maintenance of such action or
     proceeding;

          (d) consents to the service of any and all process in any such action
     or proceeding by the mailing of copies of such process to such the Borrower
     at its address specified in (S) 12.02; and
                                 ---------     

          (e) agrees that a final judgment in any such action or proceeding
     shall be conclusive and may be enforced in other jurisdictions by suit on
     the judgment or in any other manner provided by law.

Nothing in this (S) 12.11 shall affect the right of the Administrative Agent or
                ---------                                                      
any Lender to serve legal process in any other manner permitted by law or affect
the right of the Administrative Agent or any Lender to bring any action or
proceeding against any the Borrower or its property in the courts of other
jurisdictions.

     Section 12.12  Limitation of Liability.  None of the Administrative Agent,
     -------------  -----------------------                                    
any Lender or any Affiliate, officer, director, employee, attorney or agent
thereof shall be liable for any error of judgment or act done in good faith, or
be otherwise liable or responsible under any circumstances whatsoever (including
such Person's negligence), except for such Person's gross negligence or willful
misconduct.  None of the Administrative Agent, any Lender or any Affiliate,
officer, director, employee, attorney or agent thereof shall have any liability
with respect to, and the Borrower hereby waives, releases and agrees not to sue
any of them upon any claim for any special, indirect, incidental or
consequential damages suffered or incurred by the Borrower or any other Loan
Party in connection with, arising out of or in any way related to this Agreement
or any of the other Loan Documents, or any of the transactions contemplated by
this Agreement or any of the other Loan Documents.  The Borrower hereby waives,
releases and agrees not to sue the Administrative Agent or any Lender or any of
their respective Affiliates, officers, directors, employees, attorneys or agents
for exemplary or punitive damages in respect of any claim in connection with,
arising out of or in any way related 

                                     -126-
<PAGE>
 
to this Agreement or any of the other Loan Documents, or any of the transactions
contemplated by this Agreement or any of the other Loan Documents.

     Section 12.13  No Duty.  All attorneys, accountants, appraisers and other
     -------------  -------                                                   
professional Persons and consultants retained by the Administrative Agent and
the Lenders shall have the right to act exclusively in the interest of the
Administrative Agent and the Lenders and shall have no duty of disclosure, duty
of loyalty, duty of care or other duty or obligation of any type or nature
whatsoever to the Borrower of any of its Subsidiaries or any of their
shareholders or any other Person.

     Section 12.14  No Fiduciary Relationship; No Agency Relationship.  The
     -------------  -------------------------------------------------      
relationship between the Borrower and each Lender is solely that of debtor and
creditor, and neither the Administrative Agent nor any Lender has any fiduciary
or other special relationship with the Borrower or any other Loan Party, and no
term or condition of any of the Loan Documents shall be construed so as to deem
the relationship between the Borrower and any Lender, or any other Loan Party
and any Lender, to be other than that of debtor and creditor.  No joint venture
or partnership is created by this Agreement among the Lenders or among the
Borrower or any other Loan Party and the Lenders.  The Administrative Agent
shall not be deemed to have any fiduciary relationship with any Lender or any
Loan Party, and no implied covenants, functions, responsibilities, duties,
obligations or liabilities shall be read into this Agreement or otherwise exist
against the Administrative Agent.  Without limiting the generality of the
foregoing, the use of the term "agent" in this Agreement with respect to the
                                -----                                       
Administrative Agent is not intended to connote any fiduciary or other express
or implied obligation arising under agency doctrine of any applicable law;
instead, such term is used merely as a matter of market custom and is intended
to create or reflect only an administrative relationship among independent
contracting parties.

     Section 12.15  Waiver of Jury Trial.  Each of the Borrower, the
     -------------  --------------------                            
Administrative Agent and the Lenders irrevocably waives all right to trial by
jury in any action, proceeding or counterclaim (whether based on contract, tort
or otherwise) arising out of or relating to any of the Loan Documents, the
Advances or the actions of the Administrative Agent or any Lender in the
negotiation, administration, performance or enforcement thereof.

               the Loan Agreement. 

Omnipoint or any other Subsidiary shall make payment of funds hereunder through
additional capital or other contributions in respect of the owners' equity of
the Borrower; provided that

          (x) to the extent such purchases or contributions are prohibited under
     agreements binding on Omnipoint or D&E or both on the date hereof (the
     "Conflicting Agreements"), such of Omnipoint, D&E or both which are party
     -----------------------

     lending of funds to the Borrower by way of Subordinated Debt;

          (y) if any such payment made as such a loan may at a later time be
     made as an equity contribution to the Borrower without violating such
     Conflicting Agreements, such loan shall be converted to an equity
     contribution to the Borrower; and

          (z) each of Omnipoint and D&E shall use its best efforts to take such
     action as will permit any such loan to be converted to such an equity
     contribution.

                 ----------

Administrative Agent and each Lender for the full amount of Taxes (including,
without limitation, any Taxes imposed by any jurisdiction on amounts payable
under this Section) paid by the Administrative Agent or such Lender and any
liability (including penalties, interest and expenses) arising therefrom or with
respect thereto, whether or not such Taxes were correctly or legally asserted.
This indemnification shall be made within 30 days from the date the
Administrative Agent or such Lender (as the case may be) makes written demand
therefor.

     SECTION 3.  Obligation Absolute.  Each of Omnipoint and D&E will perform
                 -------------------

now or hereafter in effect in any jurisdiction affecting any of the terms of the
Notes, the Loan Agreement, the other Loan Documents or any other document
related thereto or the rights of the Administrative Agent or the Lenders with
respect thereto.  The obligations of each of Omnipoint and D&E under this
Agreement are independent of the Loan Agreement, the Notes and the other Loan
Documents, and a separate action or actions may be brought and prosecuted
against either of Omnipoint or D&E or both to enforce this Agreement,
irrespective of whether any action is brought against the other of Omnipoint or
D&E or the Borrower or whether Omnipoint or D&E or the Borrower is joined in any
such action or actions.  The obligations of each of Omnipoint and D&E under this
Agreement are joint and several and shall be absolute and unconditional
irrespective of:

          (i) any lack of validity or enforceability of the Loan Agreement, the
     Notes, any other Loan Document or any other agreement or instrument
     relating thereto or any collateral therefor;

          (ii) any change in the time, manner or place of payment of, or in any
     other term of, the Notes, the Loan Agreement, any other Loan Document, or
     any other amendment or waiver of or any consent to departure from the Loan
     Agreement, the Notes or any other Loan Document, including, without
     limitation, any increase in the Notes or the obligations of the Borrower
     under the Loan Agreement resulting from the extension of additional credit
     to the Borrower or any of its Subsidiaries or otherwise;

          (iii) any taking, exchange, release or non-perfection of any
     collateral, or any taking, release or amendment or waiver of or consent to
     departure from any guaranty, the Notes, the Loan Agreement or any other
     Loan Document;

          (iv) any manner of application of collateral, or proceeds thereof, to
     all or any of the obligations evidenced by the Loan Agreement, the Notes or
     any other Loan Document, or any manner of sale or other disposition of any
     collateral for all or any of the obligations evidenced by the Loan
     Agreement, the Notes or any other Loan Document or any other assets of the
     Borrower or any of its Subsidiaries;

                                      -3-
<PAGE>
 
          (v) any charge, restructuring or termination of the corporate or
     partnership structure or existence of the Borrower or any of its
     Subsidiaries; or

          (vi)  any other circumstances which might otherwise constitute a
     defense available to, or a discharge of, the Borrower or a surety.

This Agreement shall continue to be effective or be reinstated, as the case may
be, if at any time any payment of any of the Notes is rescinded or must
otherwise be returned by the Administrative Agent or any Lender upon the
insolvency, bankruptcy or reorganization of the Borrower or otherwise, all as
though such payment had not been made.

     SECTION 4.  Waiver.  Each of Omnipoint and D&E waives promptness,
                 ------                                               
diligence, notice of acceptance and any other notice with respect to the Loan
Agreement, the Notes, the other Loan Documents and this Agreement and any
requirement that the Administrative Agent or any Lender protect, secure, perfect
or insure any security interest or lien or any property subject thereto or
exhaust any right or take any action against the Borrower or any other person or
entity or any collateral.

     SECTION 5.  Separate Undertaking.  Without limiting the generality of any
                 --------------------                                         
of the foregoing provisions of this Agreement, each of Omnipoint and D&E
irrevocably waives, to the full extent permitted by applicable law and for the
benefit of, and as a separate undertaking with, the Lenders and the
Administrative Agent, any defense to the performance of this Agreement which may
be available to either of Omnipoint or D&E or both as a consequence of this
Agreement being rejected or otherwise not assumed by the Borrower or any trustee
or other similar official for the Borrower or for any substantial part of the
property of the Borrower, or as a consequence of this Agreement being otherwise
terminated or modified, in any proceeding seeking to adjudicate the Borrower a
bankrupt or insolvent, or seeking liquidation, winding up,  reorganization,
arrangement, adjustment, protection, relief or composition of the Borrower or
the debts of the Borrower under any law relating to bankruptcy, insolvency or
reorganization or relief of debtors, whether such rejection, non-assumption,
termination or modification be by reason of this Agreement being held to be an
executory contract or by reason of any other circumstance.  If this Agreement
shall be so rejected or otherwise not assumed, or so terminated or modified,
each of Omnipoint and D&E promises for the benefit of, and as a separate
undertaking with, the Lenders and the Administrative Agent, unconditionally,
jointly and severally, to pay to the Administrative Agent an amount equal to
each payment which would otherwise be payable by Omnipoint or D&E under or in
connection with this Agreement if this Agreement were not so rejected or
otherwise not assumed or were otherwise not so terminated or modified, such
amount to be payable to the Administrative Agent, at its account specified in
the Loan Agreement for the payment of amounts owing by the Borrower thereunder
(or otherwise in accordance with the instructions of the Administrative Agent),
as and when such payment would otherwise be payable hereunder and such amount to
be applied as such payment would 

                                      -4-

otherwise be applied under Section 2.07 of the Loan Agreement.
