Item 5.  Other Events.
         ------------ 

     On December 2, 1996 (the "Closing Date"), Omnipoint Corporation (the
"Company") completed the private placement of $200,000,000 of the Company's 11-
5/8% Series A Senior Notes due 2006 (the "Notes") under Rule 144A of the
Securities Act of 1933, as amended (the "Act").  The Notes have not been
registered under the Act and may not be offered or sold in the United States
absent registration or an applicable exemption from the registration
requirements thereunder.

     The Notes were issued under an indenture (the "Indenture"), dated as of
December 2, 1996 between the Company and Marine Midland Bank as trustee under
the Indenture.  Capitalized terms not otherwise defined herein are defined in
the Indenture.

     The Company has received net proceeds from the sale of the Notes of
approximately $202.0 million, after deducting the discount to the initial
purchasers of the Notes and estimated offering expenses.  As described more
fully below, approximately $37.4 million, which, together with the proceeds from
investment thereof will be sufficient to pay interest on the Notes through
August 15, 1998, has been used to fund an Escrow Account for the benefit of the
holders of the Notes.

     The Notes are senior unsecured obligations of the Company ranking pari
passu in right of payment with all existing and future senior indebtedness of
the Company and ranking senior to all existing and future subordinated
indebtedness of the Company.  The Notes will mature on August 15, 2006.
Interest on the Notes will be payable semi-annually in arrears on February 15
and August 15 of each year, commencing February 15, 1997.  Except in certain
circumstances, the Notes will not be redeemable at the option of the Company
prior to August 15, 2001.  Thereafter, the Company may redeem the Notes, in
whole or in part, at the redemption prices set forth in the Indenture, plus
accrued and unpaid interest and Liquidated Damages, if any, to the date of
redemption.  In addition, at any time prior to August 15, 1999, the Company may
redeem up to one-third of the Notes originally outstanding at a redemption price
of 111.625% of the principal amount thereof, plus accrued and unpaid interest
and Liquidated Damages, if any, to the date of redemption, with the net proceeds
of one or more Public Equity Offerings or sales of certain capital stock of the
Company to one or more Strategic Equity Investors; provided that after any such
redemption at least two-thirds of the aggregate principal amount of the Notes
originally outstanding remains outstanding.  Upon the occurrence of a Change of
Control, the Company will be required to offer to repurchase the outstanding
Notes at a price equal to 101% of the principal amount thereof, plus accrued and
unpaid interest and Liquidated Damages, if any, to the date of purchase.

     The holders of the Notes are entitled to certain registration rights,
pursuant to a Registration Rights Agreement which provides that the Company
will, at its cost, (i) within 45 days after the Closing Date, file a
registration statement (the "Exchange Offer Registration 

                                      -2-
<PAGE>
 
Statement") with the Commission with respect to a registered offer to exchange
the Notes for the Company's 11-5/8% Series A Senior Notes due 2006 (the "New
Notes"), which will have terms substantially identical in all material respects
to the notes (except that such New Notes will not contain terms with respect to
transfer restrictions) and (ii) use its best efforts to cause such Exchange
Offer Registration Statement to be declared effective under the Act within 90
days after the Closing Date.

     If for any reason the exchange offer as described above is not consummated
within 135 days of the Closing Date, the Company is obligated to (a) file a
shelf registration statement covering resales of the Notes (a "Shelf
Registration Statement"), (b) use its best efforts to cause such Shelf
Registration Statement to be declared effective under the Act as promptly as
practicable after the filing of such Registration Statement, and (c) use its
best efforts to keep effective such Shelf Registration Statement until the
earlier of 36 months following the Closing Date and such time as all of the
Notes have been sold thereunder, or otherwise cease to be a Transfer Restricted
Security (as defined in the Registration Rights Agreement).

     If neither of the registration statements described above is filed and
declared effective within the prescribed time periods or any other Registration
Defaults (as defined in the Registration Rights Agreement) occur, the Company
will pay Liquidated damages to each holder of the Notes, with respect to the
first 90-day period immediately following the occurrence of such Registration
Default in an amount equal to $.05 per week per $1,000 principal amount of the
Notes held by such holder and with respect to each subsequent 90-day period, an
additional $.05 per week per $1,000 principal amount of Notes until all
Registration Defaults have been cured, up to a maximum of liquidated damages of
$.50 per week per $1,000 principal amount of Notes (regardless of whether one or
more than one Registration Default is outstanding).

     The Indenture contains certain covenants which, among other things,
restrict the ability of the Company and any of its Restricted Subsidiaries to
incur additional indebtedness, pay dividends or make distributions of the
Company's capital stock or make certain other restricted payments, create liens,
enter into transactions with stockholders and affiliates, sell assets, or
consolidate, merge or sell all or substantially all of their assets.

     Approximately $37.4 million of the net proceeds from the offering has been
used to fund an Escrow Account for the benefit of the holders of the Notes.
$37.4 million, together with the proceeds from investment thereof, will be
sufficient to pay interest on the Notes through August 15, 1998.  Funds may be
disbursed from the Escrow Account to reimburse the Company for interest payments
the Company makes on the Notes, and, in certain circumstances, upon the
retirement of the Notes.  The balance of the net proceeds will be used for
working capital and general corporate purposes, including payment for licenses
awarded, if any, through participation in the D, E and F Block auctions being
conducted by the Federal Communications Commission.  Pending such uses, the net
proceeds of the Offering will be invested in investment-grade, interest-bearing
securities.

occurred when such Person was a Restricted Subsidiary as if such asset

          Section 2.1  Form and Dating.  The Notes and the Trustee's certificate
                       ---------------                                          
of authentication shall be substantially in the form annexed hereto as Exhibit
A.  The Notes may have notations, legends or endorsements required by law, stock
exchange agreements or requirements to which the Company is subject or usage.
The Company shall approve the form of the Notes and any notation, legend or
endorsement on the Notes.  Each Note shall be dated the date of its
authentication.

          The terms and provisions contained in the form of the Notes annexed
hereto as Exhibit A shall constitute, and are hereby expressly made, a part of
this Indenture.  To the extent applicable, the Company and the Trustee, by their
execution and delivery of this Indenture, expressly agree to such terms and
provisions and to be bound thereby.

          The Original Notes shall be issued initially in the form of (i) one or
more global notes in registered form (the "Global Notes") deposited with, or on
                                           ------------                        
behalf of, the Depositary, duly executed by the Company and authenticated by the
Trustee as hereinafter provided or (ii) definitive physical certificates in
registered form for delivery to the record holders who are institutional
"accredited investors" under Regulation D under the Securities Act (the
"Accredited Investor Notes"), duly executed by the Company and authenticated by
the Trustee as hereinafter provided.  The Exchange Notes initially shall be
issued in the form of one or more Global Notes.  Each Global Note shall bear
such legend as may be required or reasonably requested by the Depositary.

          The definitive Notes shall be typed, printed, lithographed or engraved
or produced by any combination of these methods or may be produced in any other
manner permitted by the rules of any securities exchange on which the Notes may
be listed, all as determined by the officers executing such Notes, as evidenced
by their execution of such Notes.

          Section 2.2  Execution, Authentication and Denominations.  Two
                       -------------------------------------------      
Officers shall execute the Notes for the Company by facsimile or manual
signature in the name and on behalf of the Company.

          If an Officer whose signature is on a Note no longer holds that office
at the time the Trustee or an authenticating agent authenticates the Note, the
Note shall be valid nevertheless.

                                      25
<PAGE>
 
          A Note shall not be valid until the Trustee or an authenticating agent
manually signs the certificate of authentication on the Note.  The signature
shall be conclusive evidence that the Note has been authenticated under this
Indenture.

          Pursuant to and based upon a Company Order, the Trustee or an
authenticating agent shall authenticate for original issue Original Notes in the
aggregate principal amount of $200,000,000 and shall authenticate for original
issue Exchange Notes up to an aggregate principal amount of $200,000,000,
provided that such Exchange Notes shall be issuable only upon the valid
surrender for cancellation of Original Notes of a like aggregate principal
amount in the Exchange Offer.  Such Company Order shall specify the amount of
the Notes to be authenticated and the date on which the original issue of Notes
is to be authenticated.  The aggregate principal amount of Notes outstanding at
any time may not exceed the amount set forth above except for Notes
authenticated and delivered upon registration of transfer of, or in exchange
for, or in lieu of, other Notes pursuant to Section 2.6 or 2.7.

          The Trustee may appoint an authenticating agent to authenticate Notes.
An authenticating agent may authenticate Notes whenever the Trustee may do so,
except with regard to the original issuance of the Notes.  Except as provided in
the preceding sentence, each reference in this Indenture to authentication by
the Trustee includes authentication by such authenticating agent.  An
authenticating agent has the same rights as an Agent to deal with the Company or
an Affiliate of the Company.  The provisions of 7.1, 7.2 and 7.6 hereof shall be
applicable to any authenticating agent.

          The Notes shall be issuable only in registered form without coupons
and only in denominations of $1,000 in principal amount and any integral
multiple thereof.

          Section 2.3  Registrar and Paying Agent.  The Company shall maintain
                       --------------------------                             
an office or agency where Notes may be presented for registration of transfer or
for exchange (the "Registrar"), an office or agency where Notes may be presented
                   ---------                                                    
for payment (the "Paying Agent") and an office or agency where notices and
                  ------------                                            
demands to or upon the Company in respect of the Notes and this Indenture may be
served.  The Company shall cause the Registrar to keep a register of the Notes
and of their 

                                      26
<PAGE>
 
transfer and exchange (the "Security Register").  The Security Register
                            -----------------                 
shall be in written form or any other form capable of being converted into
written form within a reasonable time. The Company may have one or more co-
Registrars and one or more additional Paying Agents.

          The Company shall enter into an appropriate agency agreement with any
Agent not a party to this Indenture.  The agreement shall implement the
provisions of this Indenture that relate to such Agent.  The Company shall give
prompt written notice to the Trustee of the name and address of any such Agent
and any change in the address of such Agent.  If the Company fails to maintain a
Registrar, Paying Agent and/or agent for service of notices and demands, the
Trustee shall act as such Registrar, Paying Agent and/or agent for service of
notices and demands.  The Company may remove any Agent upon written notice to
such Agent and the Trustee; provided that no such removal shall become effective
until (i) the acceptance of an appointment by a successor Agent to such Agent as
evidenced by an appropriate agency agreement entered into by the Company and
such successor Agent and delivered to the Trustee or (ii) notification to the
Trustee that the Trustee shall serve as such Agent until the appointment of a
successor Agent in accordance with clause (i) of this proviso.  The Company, any
Subsidiary of the Company, or any Affiliate of any of them may act as Paying
Agent, Registrar or co-Registrar, and/or agent for service of notice and
demands.

          The Company initially appoints the Trustee as Registrar, Paying Agent
and agent for service of notice and demands.  If, at any time, the Trustee is
not the Registrar, the Company shall furnish, or cause to be furnished, to the
Trustee on or before each Interest Payment Date and at such other times as the
Trustee may reasonably request in writing, the names and addresses of the
Holders as they appear in the Security Register.  At the option of the Company,
payment of interest may be made by check mailed to the address of the Holders as
such address appears in the Security Register.

          Section 2.4  Paying Agent to Hold Money in Trust.  Not later than each
                       -----------------------------------                      
due date of the principal, premium and Liquidated Damages, if any, and interest
on any Notes, the Company shall deposit with the Paying Agent money in
immediately available funds sufficient to pay such principal, premium and
Liquidated Damages, if any, and interest so becoming due.  The Company shall
require each Paying Agent other than the Trustee to agree in writing that such
Paying Agent 

                                      27
<PAGE>
 
shall hold in trust for the benefit of the Holders or the Trustee all money held
by the Paying Agent for the payment of principal of, premium and Liquidated
Damages, if any, and interest on the Notes (whether such money has been paid to
it by the Company or any other obligor on the Notes), and such Paying Agent
shall promptly notify the Trustee of any default by the Company (or any other
obligor on the Notes) in making any such payment. The Company at any time may
require a Paying Agent to pay all money held by it to the Trustee and account
for any funds disbursed, and the Trustee may at any time during the continuance
of any payment default, upon written request to a Paying Agent, require such
Paying Agent to pay all money held by it to the Trustee and to account for any
funds disbursed. Upon doing so, the Paying Agent shall have no further liability
for the money so paid over to the Trustee.

          Section 2.5  Transfer and Exchange.  When Notes are presented to the
                       ---------------------                                  
Registrar or a co-Registrar with a request to register the transfer or to
exchange them for an equal principal amount of Notes of other authorized
denominations, the Registrar shall register the transfer or make the exchange as
requested if its requirements for such transactions are met.  To permit
registrations of transfers and exchanges, the Company shall execute and the
Trustee shall authenticate Notes at the Registrar's request.  No service charge
shall be made for any registration of transfer or exchange of the Notes, but the
Company may require payment of a sum sufficient to cover any transfer tax or
similar governmental charge payable in connection therewith (other than any such
transfer taxes or other similar governmental charge payable upon exchanges
pursuant to Section 2.8, 3.8 or 9.4).

          The Registrar shall not be required (i) to issue, register the
transfer of or exchange any Note during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of
Notes selected for redemption under Section 3.3 and ending at the close of
business on the day of such mailing, or (ii) to register the transfer of or
exchange any Note so selected for redemption in whole or in part, except the
unredeemed portion of any Note being redeemed in part.

          Notwithstanding any other provisions of this Section 2.5, unless and
until it is exchanged in whole or in part for Notes in definitive registered
form, a Global Note representing all or a portion of the Notes may not be
transferred except as a whole by the Depositary to a nominee of such Depositary
or by a nominee of such 

                                      28
<PAGE>
 
Depositary to such Depositary or another nominee of such Depositary or by such
Depositary or any such nominee to a successor Depositary or a nominee of such
successor Depositary.

          If the Depositary notifies the Company that it is unwilling or unable
to continue as Depositary for the Global Notes or if at any time the Depositary
shall no longer be eligible under the next sentence of this paragraph, the
Company shall appoint a successor Depositary with respect to the Notes.  Each
Depositary appointed pursuant to this Section 2.5 must, at the time of its
appointment and at all times while it serves as Depositary, be a clearing agency
registered under the Exchange Act and any other applicable statute or
regulation.  The Company will execute, and the Trustee will authenticate and
deliver, Notes in definitive registered form in any authorized denominations, in
an aggregate principal amount equal to the principal amount of the Global Note
or Notes representing such Notes in exchange for such Global Note or Notes if
the Depositary notifies the Company that it is unwilling or unable to continue
as Depositary for the Global Notes or if any time the Depositary shall no longer
be eligible to serve as Depositary and a successor Depositary for the Notes is
not appointed by the Company within 90 days after the Company receives such
notice or becomes aware of such ineligibility.

          The Company may at any time and in its sole discretion determine that
the Notes shall no longer be represented by a Global Note or Notes.  In such
event the Company will execute, and the Trustee will authenticate and deliver,
Notes in definitive registered form in any authorized denominations, in an
aggregate principal amount equal to the principal amount of the Global Note or
Notes representing such Notes in exchange for such Global Note or Notes.

          Upon the exchange of a Global Note for Notes in definitive registered
form without coupons, in authorized denominations, such Global Note shall be
cancelled by the Trustee.  Notes in definitive registered form issued in
exchange for a Global Note pursuant to this Section 2.5 shall be registered in
such names and in such authorized denominations as the Depositary for such
Global Note, pursuant to instructions from its direct or indirect participants
or otherwise, shall instruct the Trustee.  The Trustee shall deliver such Notes
to or as directed by the Persons in whose names such Notes are so registered.

                                      29

     Notwithstanding the foregoing, transfer of Original Notes which are
Accredited Investor Notes may be registered only when accompanied by the
following additional information and documents as applicable:

               (i)  If such Accredited Investor Note is being delivered to the
     Registrar by a Holder for registration in the name of such Holder, without
     transfer, a certification from such Holder to that effect (in substantially
     the form set forth on the reverse of the Note); or

               (ii) If such Accredited Investor Note is being transferred (a)
     to a Person who the seller reasonably believes is a qualified institutional
     buyer (as defined in Rule 144A under the Securities Act) in a transaction
     meeting the requirements of Rule 144A, (b) in a transaction meeting the
     requirements of Rule 144 under the Securities Act, (c) outside the United
     States to a foreign person in a transaction meeting the requirements of
     Rule 904 under the Securities Act or (d) in accordance with another
     exemption from the registration requirements of the Securities Act, a
     certification from such Holder to that effect (in substantially the form
     set forth on the reverse of the Note) and, in the case of (d), if the
     Company so requests, an Opinion of Counsel.

     Any Accredited Investor Note transferred pursuant to Rule 144A or Rule 144
under the Securities Act shall thereafter be represented by a Global Note.

     All Notes issued upon any registration of transfer or exchange of Notes
shall be valid obligations of the Company, evidencing the same debt, and
entitled to the same benefits under this Indenture, as the Notes surrendered
upon such registration of transfer or exchange.

     Section 2.6  Replacement Notes.  If a mutilated Note is surrendered to the
                  -----------------                                            
Trustee or if the Holder claims that the Note has been lost, destroyed or
wrongfully taken, then, in the absence of notice to the Company or the Trustee
that such Note has been acquired by a bona fide purchaser, the Company shall
issue and the Trustee shall authenticate a replacement Note of like tenor and
principal amount; provided that the requirements of this Section 2.6 are met.
If required by the 

                                      30
<PAGE>
 
Trustee or the Company, an indemnity bond must be furnished that is sufficient
in the judgment of both the Trustee and the Company to protect the Company, the
Trustee or any Agent from any loss that any of them may suffer if a Note is
replaced. The Company may charge such Holder for the expenses of the Company and
the Trustee in replacing a Note. In case any such mutilated, lost, destroyed or
wrongfully taken Note has become or is about to become due and payable, the
Company in its discretion may pay such Note instead of issuing a new Note in
replacement thereof.

     Every replacement Note is an additional obligation of the Company and shall
be entitled to the benefits of this Indenture.

     The provisions of this Section 2.6 are exclusive and shall preclude (to the
extent lawful) all other rights and remedies against the Company and the Trustee
with respect to the replacement or payment of mutilated, destroyed, lost or
wrongfully taken Notes.

     Section 2.7  Outstanding Notes.  Notes outstanding at any time are all
                  -----------------                                        
Notes that have been authenticated by the Trustee except for those cancelled by
it, those delivered to it for cancellation and those described in this Section
2.7 as not outstanding.

     If a Note is replaced pursuant to Section 2.6, it ceases to be outstanding
unless and until the Trustee and the Company receive proof satisfactory to each
of them that the replaced Note is held by a bona fide purchaser.

     If the Paying Agent (other than the Company or an Affiliate of the Company)
holds on a Redemption Date or the maturity date money sufficient to pay Notes
payable on that date, then on and after that date such Notes cease to be
outstanding and interest on them shall cease to accrue.

     Notes, or portions thereof, for the payment or redemption of which moneys
or U.S. Government Obligations (as provided for in Article VIII) in the
necessary amount shall have been deposited in trust with the Trustee or with any
Paying Agent (other than the Company) or shall have been set aside, segregated
and held in trust by the Company for the Holders of such Notes (if the Company
shall act as its own Paying Agent), on and after that time shall cease to be
outstanding and, in 

                                      31
<PAGE>
 
the case of redemption, interest on such Notes shall cease to accrue, provided
that if such Notes, or portions thereof, are to be redeemed prior to the
maturity thereof, notice of such redemption shall have been given as herein
provided, or provision satisfactory to the Trustee shall have been made for
giving such notice.

     A Note does not cease to be outstanding because the Company or one of its
Affiliates holds such Note, provided, however, that, in determining whether the
Holders of the requisite principal amount of the outstanding Notes have given
any request, demand, authorization, direction, notice, consent or waiver
hereunder, Notes owned by the Company or any other obligor upon the Notes or any
Affiliate of the Company or of such other obligor shall be disregarded and
deemed not to be outstanding, except that in determining whether the Trustee
shall be protected in relying upon any such request, demand, authorization,
direction, notice, consent or waiver, only Notes which a Responsible Officer of
the Trustee has actual knowledge to be so owned shall be so disregarded.  Notes
so owned which have been pledged in good faith may be regarded as outstanding if
the pledgee establishes to the satisfaction of the Trustee the pledgee's right
so to act with respect to such Notes and that the pledgee is not the Company or
any other obligor upon the Notes or any Affiliate of the Company or of such
other obligor.

     Section 2.8  Temporary Notes.  Until definitive Notes are ready for
                  ---------------                                       
delivery, the Company may prepare and the Trustee shall authenticate temporary
Notes.  Temporary Notes shall be substantially in the form of definitive Notes
but may have insertions, substitutions, omissions and other variations
determined to be appropriate by the Officers executing the temporary Notes, as
evidenced by their execution of such temporary Notes.  If temporary Notes are
issued, the Company will cause definitive Notes to be prepared without
unreasonable delay.  After the preparation of definitive Notes, the temporary
Notes shall be exchangeable for definitive Notes upon surrender of the temporary
Notes at the office or agency of the Company designated for such purpose
pursuant to Section 4.2, without charge to the Holder.  Upon surrender for
cancellation of any one or more temporary Notes the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Notes of authorized denominations.  Until so exchanged, the
temporary Notes shall be entitled to the same benefits under this Indenture as
definitive Notes.

                                      32
<PAGE>
 
     Section 2.9  Cancellation.  The Company at any time may deliver, or cause
                  ------------                                                
to be delivered, Notes to the Trustee for cancellation.  The Registrar and the
Paying Agent shall forward to the Trustee any Notes surrendered to them for
transfer, exchange or payment.  The Trustee (and no one else) shall cancel all
Notes surrendered for registration of transfer, exchange, payment, replacement
or cancellation and shall destroy them in accordance with its normal procedure.

     Section 2.10  CUSIP Numbers.  The Company in issuing the Notes may use
                   -------------                                           
"CUSIP" numbers (if then generally in use), and the Company and the Trustee
shall use CUSIP numbers in notices of redemption or exchange as a convenience to
Holders; provided that any such notice shall state that no representation is
made as to the correctness of such CUSIP numbers either as printed on the Notes
or as contained in any notice of redemption or exchange and that reliance may be
placed only on the other identification numbers printed on the Notes; and
provided further that failure to use CUSIP numbers in any notice of redemption
or exchange shall not affect the validity or sufficiency of such notice.  The
Company shall promptly notify the Trustee of any change in CUSIP numbers.

     Section 2.11  Defaulted Interest.  If the Company defaults in a payment of
                   ------------------                                          
interest on the Notes, it shall pay, or shall deposit with the Paying Agent
money in immediately available funds sufficient to pay the defaulted interest,
plus (to the extent lawful) any interest payable on the defaulted interest, to
the Persons who are Holders on a subsequent special record date.  A special
record date, as used in this Section 2.11 with respect to the payment of any
defaulted interest, shall mean the 15th day next preceding the date fixed by the
Company for the payment of defaulted interest, whether or not such day is a
Business Day.  At least 15 days before the subsequent special record date, the
Company shall mail to each Holder and to the Trustee a notice that states the
subsequent special record date, the payment date and the amount of defaulted
interest to be paid.

release their Guarantee by such Restricted Subsidiary (including any deemed
release upon payment in full of all obligations under such Indebtedness, except

Person that is not such a holder or an Affiliate.

     In addition to the foregoing, transactions with any holder (or any

on any of its assets or properties of any character, or any shares of Capital
Stock or Indebtedness of any Restricted Subsidiary, without making effective
provision for all of the Notes and all other amounts due under the Indenture to
be directly secured equally and ratably with (or, if the obligation or liability
to be secured by such Lien is subordinated in right of payment to the Notes,
prior to) the obligation or liability secured by such Lien.

               (i)  Liens existing on the Closing Date;

     Section 4.3;

                                      49

               (v)  Liens securing Indebtedness under clauses (i), (ii) or (iii)
     of the second paragraph of Section 4.3 granted on or after the Closing Date

     person is merged into, or the assets of such person are acquired by, the
     Company or any Restricted Subsidiary, provided that such Liens were in
     existence prior to the contemplation of such merger or acquisition and do
     not secure any property or assets of the Company or any of its Restricted
     Subsidiaries other than the property or assets subject to the Liens prior
     to such merger or acquisition; or

               (viii)  Permitted Liens.

     Section 4.10  Limitation on Sale-Leaseback Transactions. The Company will
                   -----------------------------------------                  
not, and will not permit any Restricted Subsidiary to, enter into any sale-
leaseback transaction involving any of its assets or properties whether now
owned or hereafter acquired, whereby the Company or a Restricted Subsidiary
sells or transfers such assets or properties and then or thereafter leases such
assets or properties or any part thereof or any other assets or properties which
the Company or such Restricted Subsidiary, as the case may be, intends to use
for substantially the same purpose or purposes as the assets or properties sold
or transferred.

     Section 4.11  Limitation on Asset Sales.  The Company will not, and will
                   -------------------------                                 
not permit any Restricted Subsidiary to, consummate any Asset Sale, unless (i)
the consideration received by the Company or such Restricted Subsidiary is at
least equal to the fair market value of the assets sold or disposed of and (ii)
at least 75% of the consideration received consists of cash or Temporary Cash
Investments, provided, however, that the amount of (x) any liabilities of the
Company or any 

                                      50
<PAGE>
 
Restricted Subsidiary that are assumed by the transferee of any
such assets and (y) any notes or other obligations received by the Company or
any such Restricted Subsidiary from such transferee that are immediately
converted by the Company or such Restricted Subsidiary into cash, shall be
deemed to be Temporary Cash Investments (to the extent of the Temporary Cash
Investments received in such conversion) for the purposes of this clause (ii).
In the event and to the extent that the Net Cash Proceeds received by the
Company or any of its Restricted Subsidiaries from one or more Asset Sales
occurring after the Closing Date in any period of twelve consecutive months
exceed $5 million, then the Company shall or shall cause the relevant Restricted
Subsidiary to (1) within twelve months after the date Net Cash Proceeds so
received exceed such an amount (a) apply an amount equal to such excess Net Cash
Proceeds to permanently repay Indebtedness of the Company or any Restricted
Subsidiary or (b) invest an equal amount, or the amount not so applied pursuant
to clause (a) (or enter into a definitive agreement committing to so invest
within twelve months after the date of such agreement), in Telecommunications
Assets (or in a company engaged in a Telecommunications Business) and/or (2)
apply (no later than the end of the twelve-month period referred to in clause
(1)) such excess Net Cash Proceeds (to the extent not applied pursuant to clause
(1)) as provided in the following paragraph of this Section 4.11.  The amount of
such excess Net Cash Proceeds required to be applied (or to be committed to be
applied) during such twelve-month period as set forth in clause (1) of the
preceding sentence and not applied as so required by the end of such period
shall constitute "Excess Proceeds."

     If, as of the first day of any calendar month, the aggregate amount of
Excess Proceeds not theretofore subject to an Offer to Purchase pursuant to this
Section 4.11 equals or exceeds $5 million, the Company must commence, not later
than the fifteenth Business Day of such month, and consummate an Offer to
Purchase from the Holders on a pro rata basis an aggregate principal amount of
Notes equal to the Excess Proceeds on such date, at a purchase price equal to
100% of the principal amount of the Notes, plus, in each case accrued interest
(if any) to the Payment Date.  Notwithstanding the foregoing, to the extent that
any amount of Excess Proceeds remains after completion of any such Offer to
Purchase, the Company may use such remaining amount for general corporate
purposes and the amount of Excess Proceeds shall be reset to zero.

the Company may distribute all or a portion of the capital stock of any
Subsidiary holding only the assets of the technology business of the Company to
the Company's shareholders, provided that after giving effect to such
transaction on a pro forma basis (A) the Company would be permitted to incur
additional indebtedness pursuant to the first paragraph of Section 4.3, or (B)
the Company's Annualized Consolidated EBITDA would not decrease.

the Company will do or cause to be done all things necessary to preserve and

preservation thereof is no longer desirable in the conduct of the business of
the Company and its Restricted Subsidiaries taken as a whole; and provided
further that any Restricted Subsidiary may consolidate with, merge into, or
sell, convey, transfer, lease or otherwise dispose of all or part of its
property and assets to the Company or any Wholly Owned Restricted Subsidiary.

Company or any such Subsidiary, (b) the income or profits of any such
Subsidiary which is a corporation or (c) the property of the Company or any such
Subsidiary and (ii) all material lawful claims for labor, materials and supplies

or claim the amount, applicability or validity of which is being contested in
good faith by appropriate proceedings and for which adequate reserves have been
established.

condition, repair and working order and supplied with all necessary equipment
adequate for the level or stage of the Company's or any Restricted Subsidiary's
business and will cause to be made all necessary repairs, renewals,
replacements, betterments and improvements thereof, all as in the judgment of
the Company may be necessary so that the business carried on in connection
therewith may be properly and advantageously conducted at all times; provided
that nothing in this Section 4.16 shall prevent the Company or any such
Restricted Subsidiary from discontinuing the use, operation or maintenance of
any of such properties or disposing of any of them, if such discontinuance or
disposal is, in the judgment of the Board of Directors or the board of directors
of such Restricted Subsidiary having managerial responsibility for any such
property, desirable in the conduct of the business of the Company or such
Restricted Subsidiary.

     The Company will provide or cause to be provided, for itself and its
Restricted Subsidiaries, insurance against loss or damage of the kinds
customarily insured against by corporations similarly situated and owning like
properties, including, but not limited to, products liability insurance and
public liability insurance, with reputable insurers or with the government of

Officers' Certificate delivered to the Trustee pursuant to paragraph (a) of this
Section 4.17 and (iii) whether, in connection with their audit examination,
anything came to their attention that caused them to believe that the Company

in effect at the date of such examination.

          (c)  The Company shall, so long as any of the Notes are outstanding,

time insist upon, or plead, or in any manner whatsoever claim or take the

that would prohibit or forgive the Company from paying all or any portion of the
principal of, premium and Liquidated Damages, if any, or interest on the Notes
as contemplated herein, wherever enacted, now or at any time hereafter in force,
or that may affect the covenants or the performance of this Indenture; and (to
the extent that it may lawfully do so) the Company hereby expressly waives all

Default specified in clause (g) or (h) of Section 6.1 that occurs with respect
to the Company) occurs and is continuing under the Indenture, the Trustee or the
Holders of at least 25% in aggregate principal amount of the Notes then
outstanding by written notice to the Company (and to the Trustee if such notice
is given by the Holders), may, and the Trustee at the request of such Holders
shall, declare the principal amount of, premium and Liquidated Damages, if any,
and accrued interest on the Notes to be immediately due and payable.  Upon a
declaration of 

                                      58
<PAGE>
 
acceleration, such principal amount of, premium and Liquidated Damages, if any,
and accrued interest shall be immediately due and payable. In the event of a
declaration of acceleration because an Event of Default set forth in clause (e)
of Section 6.1 has occurred and is continuing, such declaration of acceleration
shall be automatically rescinded and annulled if the event of default triggering
such Event of Default pursuant to clause (e) shall be remedied or cured by the
Company or the relevant Significant Subsidiary or waived by the holders of the
relevant Indebtedness within 60 days after the declaration of acceleration with
respect thereto. If an Event of Default specified in clause (g) or (h) above
occurs with respect to the Company, the principal amount of, premium and
Liquidated Damages, if any, and accrued interest on the Notes then outstanding
shall ipso facto become and be immediately due and payable without any
declaration or other act on the part of the Trustee or any Holder.

     At any time after such a declaration of acceleration, but before a judgment
or decree for the payment of the money due has been obtained by the Trustee, the
Holders of at least a majority in principal amount of the outstanding Notes, by
written notice to the Company and to the Trustee may waive all past Defaults and
rescind and annul such declaration of acceleration and its consequences if (a)
the Company has paid or deposited with the Trustee a sum sufficient to pay (i)
all sums paid or advanced by the Trustee hereunder and the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel and all other amounts due to the Trustee pursuant to Section 7.6
hereof, (ii) all overdue interest on all Notes, (iii) the principal of and
premium and Liquidated Damages, if any, on any Securities that have become due
otherwise than by such declaration or occurrence of acceleration and interest
thereon at the rate prescribed therefor by such Notes, and (iv) to the extent
that payment of such interest is lawful, interest upon overdue interest, if any,
at the rate prescribed therefor by such Notes, (b) all existing Events of
Default, other than the nonpayment of the principal amount of, premium and
Liquidated Damages, if any, and interest on the Notes that have become due
solely by such declaration of acceleration have been cured or waived and (c) the
rescission would not conflict with any judgment or decree of a court of
competent jurisdiction.

     Section 6.3  Other Remedies.  If an Event of Default occurs and is
                  --------------                                       
continuing, the Trustee may pursue any available remedy by proceeding at law or
in equity to collect the payment of principal of, premium and Liquidated
Damages, 

                                      59

the Holders of at least a majority in aggregate principal amount of the
outstanding Notes, by notice to the Trustee, may waive an existing Default or
Event of Default and its consequences, except a Default in the payment of
principal of, premium and Liquidated Damages, if any, or interest on any Note as
specified in clause (a) or (b) of Section 6.1 (including in connection with an
Offer to Purchase) or in respect of a covenant or provision of this Indenture
which cannot be modified or amended without the consent of the Holder of each
outstanding Note affected.  Upon any such waiver, such Default shall cease to
exist, and any Event of Default arising therefrom shall be deemed to have been
cured, for every purpose of this Indenture; but no such waiver shall extend to
any subsequent or other Default or Event of Default or impair any right
consequent thereto.

     Section 6.5  Control by Majority.  The Holders of at least a majority in
                  -------------------                                        
aggregate principal amount of the outstanding Notes, by notice to the Trustee,
may direct the time, method and place of conducting any proceeding for
exercising any remedy available to the Trustee or exercising any trust or power
conferred on the Trustee; provided that the Trustee may refuse to follow any
direction that conflicts with law or this Indenture, that may involve the
Trustee in personal liability, or that the Trustee determines in good faith may
be unduly prejudicial to the rights of Holders not joining in the giving of such
direction; and provided further that the Trustee may take any other action it
deems proper that is not inconsistent with any directions received from Holders
of Notes pursuant to this Section 6.5.

     Section 6.6  Limitation on Suits.  A Holder may not institute any

proceedings, judicial or otherwise, with respect to this Indenture or the Notes,

hereunder, unless:

               (i)  such Holder has previously given  to the Trustee written
     notice of a continuing Event of Default;

                                      60
<PAGE>
 
               (ii)  the Holders of at least 25% in aggregate principal amount
     of outstanding Notes have made a written request to the Trustee to
     institute proceedings in respect of such Event of Default in its own name
     as Trustee hereunder;

               (iii) such Holder or Holders have offered the Trustee indemnity
     reasonably satisfactory to the Trustee against any costs, liabilities or
     expenses to be incurred in compliance with such request;

               (iv)  the Trustee for 60 days after its receipt of such notice,
     request and offer of indemnity has failed to institute any such proceeding;
     and

               (v)   during such 60-day period, the Holders of a majority in
     aggregate principal amount of the outstanding Notes have not given the
     Trustee a direction that is inconsistent with such written request.

                  ------------------------------------                      
other provision of this Indenture, the right of any Holder of a Note to receive
payment of the principal of, premium or Liquidated Damages, if any, or interest
on such Holder's Note on or after the respective due dates expressed on such
Note (including in a notice with respect to an Offer to Purchase), or to bring
suit for the enforcement of any such payment on or after such respective dates,
shall not be impaired or affected without the consent of such Holder.

     Section 6.8  Collection Suit by Trustee.  If an Event of Default in payment
                  --------------------------                                    
of principal, premium and Liquidated Damages, if any, or interest specified in
clause (a) or (b) of Section 6.1 occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust against the
Company or any other obligor of the Notes for the whole amount of principal,
premium and Liquidated Damages, if any, and accrued interest remaining unpaid,
together with interest on overdue principal, premium and Liquidated Damages, if
any, and, to the extent that payment of such interest is lawful, interest on
overdue installments of interest, in each case at the rate specified in the
Notes, and such further amount as shall be sufficient to cover the costs and
expenses of collection, including the

any other obligor of the Notes), its creditors or its property and shall be
entitled and empowered to collect and receive any monies, securities or other
property payable or deliverable upon conversion or exchange of the Notes or upon
any such claims and to distribute the same, and any custodian, receiver,

making of such payments directly to the Holders, to pay to the Trustee any
amount due to it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agent and counsel, and any other amounts due the
Trustee under Section 7.6.  Nothing herein contained shall be deemed to empower
the Trustee to authorize or consent to, or accept or adopt on behalf of any
Holder, any plan of reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Holder thereof, or to authorize the
Trustee to vote in respect of the claim of any Holder in any such proceeding.

Holder has instituted any proceeding to enforce any right or remedy under this
Indenture and such proceeding has been discontinued or abandoned for any reason,
or has been determined adversely to the Trustee or to such Holder, then, and in
every case, subject to any determination in such proceeding, the Company, the

by this Article VI or by law to the Trustee or to the Holders may be exercised
from time to time, and as often as may be deemed expedient, by the Trustee or by
the Holders, as the case may be.

<PAGE>
 
exercise or use under the circumstances in the conduct of such person's own

or waived; provided, however, that, except in the case of a default in the
payment of the principal of, premium and Liquidated Damages, if any, or interest
on any Note, the Trustee shall be protected in withholding such notice if and so
long as the board of directors, the executive committee or a trust committee of
directors and/or Responsible Officers of the Trustee in good faith determine
that the withholding of such notice is in the interest of the Holders.

     The Trustee shall not be deemed to have knowledge of any Default or Event
of Default except (i) a default described in Section 6.1(a) or (b) so long as
the Trustee is the Paying Agent or (ii) any Default or Event of Default of which
the Trustee shall have received written notification or a Responsible Officer

30, beginning with June 30, 1997, the Trustee shall mail to each Holder as
provided in TIA Section 313(c) a brief report dated as of such June 30, if
required by TIA Section 313(a).

     A copy of each report at the time of its mailing to the Holders of Notes
shall be mailed to the Company and filed with the Commission and each stock
exchange on which the Notes are listed in accordance with TIA Section 313(d).
The Company shall promptly notify the Trustee when the Notes are listed on any
stock exchange or of any delisting thereof.

     Section 7.6  Compensation and Indemnity.  The Company shall pay to the
                  --------------------------                               
Trustee such compensation as shall be agreed upon in writing for its services
hereunder.  The compensation of the Trustee shall not be limited by any law on
compensation of a trustee of an express trust.  The Company shall reimburse the
Trustee promptly upon request for all reasonable disbursements, expenses and

                                      68
<PAGE>
 
advances incurred or made by it in addition to compensation for its services.
Such expenses shall include the reasonable compensation, disbursements and
expenses of the Trustee's agents and counsel.

     The Company shall indemnify the Trustee for, and hold it harmless against,
any loss or liability or expense (including, without limitation, reasonable
attorneys' fees) incurred by it without negligence or bad faith on its part in
connection with the acceptance or administration of this Indenture and its
duties under this Indenture and the Notes, including the costs and expenses of
defending itself against any claim or liability and of complying with any
process served upon it or any of its officers in connection with the exercise or
performance of any of its powers or duties under this Indenture and the Notes.
The Trustee shall notify the Company promptly of any claim asserted against the
Trustee for which it may seek indemnity.  The Company shall defend the claim and
the Trustee shall cooperate in the defense.  The Trustee may have separate
counsel and the Company shall pay reasonable fees and expenses of such counsel.
The Company need not pay for any settlements made without its consent; provided
that such consent shall not be unreasonably withheld.  The Company need not
reimburse any expense or indemnity against any loss or liability incurred by the
Trustee through negligence or bad faith.

     The Trustee shall have a claim prior to the Notes on all money or property
held or collected by the Trustee, in its capacity as Trustee, for any amount
owing it pursuant to this Section 7.6, except money or property held in trust to
pay principal of, premium and Liquidated Damages, if any, and interest on
particular Notes.

     If the Trustee incurs expenses or renders services after the occurrence of
an Event of Default specified in clause (g) or (h) of Section 6.1, the expenses
and the compensation for the services (including the reasonable fees and
expenses of its agents and counsel) will be intended to constitute expenses of
administration under Title 11 of the United States Bankruptcy Code or any
applicable federal or state law for the relief of debtors.

     To the extent that the payment of any such compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under this Section 7.6 out of the estate in any such

                                      69

proceeding, shall be denied for any reason, other than solely because of the
misconduct of the Trustee or its Agents, payment of the same shall be secured by
a Lien on, and shall be paid out of, any and all distributions, dividends,
money, securities and other properties that the Holders may be entitled to
receive in such proceeding whether in liquidation or under any plan of
reorganization or arrangement or otherwise.

     The provisions of this Section 7.6 shall survive the resignation or removal
of the Trustee and the termination of this Indenture.

     The Trustee shall comply with the provisions of TIA Section 313(b)(2) to
the extent applicable.

     Section 7.7  Replacement of Trustee.  A resignation or removal of the
                  ----------------------                                  
Trustee and appointment of a successor Trustee shall become effective only upon
the successor Trustee's acceptance of appointment as provided in this Section
7.7.

     The Trustee may resign by so notifying the Company in writing at least 30
days prior to the date of the proposed resignation.  The Holders of a majority
in aggregate principal amount of the outstanding Notes may remove the Trustee by
so notifying the Trustee in writing and may appoint a successor Trustee with the
consent of the Company.  The Company may remove the Trustee if:

               (i)    the Trustee fails to comply with Section 7.9;

               (ii)   the Trustee is adjudged a bankrupt or an insolvent;

               (iii)  a receiver or other public officer takes charge of the
     Trustee or its property; or

               (iv)   the Trustee becomes incapable of acting.

     If the Trustee resigns or is removed, or if a vacancy exists in the office
of the Trustee for any reason, the Company shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the Holders
of a majority in aggregate principal amount of the outstanding Notes may appoint
a

                                      70
<PAGE>
 
successor Trustee to replace the successor Trustee appointed by the Company.
If the successor Trustee does not take office within 30 days after the retiring
Trustee resigns or is removed, the retiring Trustee, the Company or the Holders
of a majority in aggregate principal amount of the outstanding Notes may
petition any court of competent jurisdiction for the appointment of a successor
Trustee.

     A successor Trustee shall deliver a written acceptance of its appointment
to the retiring Trustee and to the Company.  Immediately after the delivery of
such written acceptance, subject to the lien provided in Section 7.6, (i) the
retiring Trustee shall transfer all property held by it as Trustee to the
successor Trustee, (ii) the resignation or removal of the retiring Trustee shall
become effective and (iii) the successor Trustee shall have all the rights,
powers and duties of the Trustee under this Indenture.  A successor Trustee
shall mail notice of its succession to each Holder.

     If the Trustee fails to comply with Section 7.9, any Holder who satisfies
the requirements of TIA Section 310(b) may petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor
Trustee.  If at any time the Trustee shall cease to be eligible in accordance
with the provisions of this Section, the Trustee shall resign immediately in the
manner and with the effect provided in this Section.

     Notwithstanding replacement of the Trustee pursuant to this Section 7.7,
the Company's obligation under Section 7.6 shall continue for the benefit of the
retiring Trustee.

with, merges or converts into, or transfers all or substantially all of its
corporate trust business to, another corporation or national banking
association, the resulting, surviving or transferee corporation or national
banking association without any further act shall be the successor Trustee with
the same effect as if the successor Trustee had been named as the Trustee
herein.

     Section 7.9  Eligibility.  Any Trustee serving hereunder shall be a bank or
                  -----------                                                   
trust company, within or without the state, which is authorized by law to
perform all of the duties imposed upon it hereby and which either (i) has a
reported capital and surplus aggregating at least $25,000,000 or (ii) is a
wholly owned subsidiary

                   -------------------                                      
interest on any money received by it except as the Trustee may agree with the
Company.  Money held in trust by the Trustee need not be segregated from other
funds except to the extent required by law and except for money held in trust
under Article VIII of this Indenture.

reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Notes to receive such payment from the money or U.S.
Government Obligations held by the Trustee or Paying Agent.

               (iv)  impair the right to institute suit for the enforcement of

               (v)  reduce the above-stated percentage of outstanding Notes the
     consent of whose Holders is necessary to modify or amend this Indenture;

               (vi)  waive a default in the payment of principal of, premium and

<PAGE>
 
               (viii)  modify any of the provisions of this Section 9.2, except
     to increase any such percentage or to provide that certain other provisions
     of this Indenture cannot be modified or waived without the consent of the
     Holder of each outstanding Note affected thereby.

     It shall not be necessary for the consent of the Holders under this Section
9.2 to approve the particular form of any proposed amendment, supplement or
waiver, but it shall be sufficient if such consent approves the substance
thereof.

     After an amendment, supplement or waiver under this Section 9.2 becomes
effective, the Company shall mail to the Holders affected thereby a notice
briefly describing the amendment, supplement or waiver.  The Company will mail
supplemental indentures to Holders upon request.  Any failure of the Company to
mail such notice, or any defect therein, shall not, however, in any way impair
or affect the validity of any such supplemental indenture or waiver.

     Section 9.3  Revocation and Effect of Consent.  Until an amendment or
                  --------------------------------                        
waiver becomes effective, a consent to it by a Holder is an continuing consent
by the Holder and every subsequent Holder of a Note or portion of a Note that
evidences the same debt as the Note of the consenting Holder, even if notation
of the consent is not made on any Note.  However, any such Holder or subsequent
Holder may revoke the consent as to its Note or portion of its Note.  Such
revocation shall be effective only if the Trustee receives the notice of
revocation before the date the amendment, supplement or waiver becomes
effective.  An amendment, supplement or waiver shall become effective on receipt
by the Trustee of written consents from the Holders of the requisite percentage
of aggregate principal amount of the outstanding Notes.

     The Company may, but shall not be obligated to, fix a record date for the
purpose of determining the Holders entitled to consent to any amendment,
supplement or waiver.  If a record date is fixed, then notwithstanding the last
two sentences of the immediately preceding paragraph, those persons who were
Holders at such record date (or their duly designated proxies) and only those
persons shall be entitled to consent to such amendment, supplement or waiver or
to revoke any consent previously given, whether or not such persons continue to
be 

                                      80
<PAGE>
 
Holders after such record date. No such consent shall be valid or effective for
more than 90 days after such record date.

     After an amendment, supplement or waiver becomes effective, it shall bind
every Holder unless it is of the type described in any of clauses (i) through
(vi) of Section 9.2.  In case of an amendment or waiver of the type described in
clauses (i) through (vi) of Section 9.2, the amendment or waiver shall bind each
Holder who has consented to it and every subsequent Holder of a Note that
evidences the same indebtedness as the Note of the consenting Holder.

     Section 9.4  Notation on or Exchange of Notes.  If an amendment, supplement
                  --------------------------------                              
or waiver changes the terms of a Note, the Trustee may require the Holder to
deliver it to the Trustee.  The Trustee may place an appropriate notation on the
Note about the changed terms and return it to the Holder and the Trustee may
place an appropriate notation on any Note thereafter authenticated.
Alternatively, if the Company or the Trustee so determines, the Company in
exchange for the Note shall issue and the Trustee shall authenticate a new Note
that reflects the changed terms.  Failure to make the appropriate notation or
issue a new Note shall not affect the validity and effect of such amendment,
supplement or waiver.

     Section 9.5  Trustee to Sign Amendments, Etc.  The Trustee shall be
                  --------------------------------                      
entitled to receive, and shall be fully protected in relying upon, in addition
to the documents required by Section 10.3 hereof, an Opinion of Counsel stating
that the execution of any amendment, supplement or waiver authorized pursuant to
this Article IX is authorized or permitted by this Indenture.  Subject to the
preceding sentence, the Trustee shall sign such amendment, supplement or waiver
if the same does not adversely affect the rights of the Trustee.  The Trustee
may, but shall not be obligated to, execute any such amendment, supplement or
waiver that affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise.

     Section 9.6  Conformity with Trust Indenture Act.  Every supplemental
                  -----------------------------------                     
indenture executed pursuant to this Article IX shall conform to the requirements
of the TIA as then in effect.

     (1)  Principal and Interest.  The Company will pay the principal of this
          ----------------------                                             
Note on August 15, 2006.

     The Company promises to pay interest on the principal amount of this Note
on each Interest Payment Date, as set forth below, at the rate per annum shown
above.

     Interest will be payable semiannually in arrears (to the holders of record
of the Notes, as reflected in the Security Register at the close of business on
the February 1 or August 1 immediately preceding the Interest Payment Date) on
each Interest Payment Date, commencing February 15, 1997.

     Interest on the Notes will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from December 2, 1996;
provided that, if there is no existing default in the payment of interest and if
this Note is authenticated between a Regular Record Date referred to on the face
hereof and the next succeeding Interest Payment Date, interest shall accrue from
such Interest Payment Date.  Interest will be computed on the basis of a 360-day
year of twelve 30-day months.

     The Company shall pay interest on overdue principal and premium and
Liquidated Damages, if any, and interest on overdue installments of interest, to
the extent lawful, at the rate borne by the Notes.

     (2)  Method of Payment.  The Company will pay interest (except defaulted
          -----------------                                                  
interest) on the principal amount of the Notes as provided above and Liquidated
Damages on each February 15 and August 15 to the persons who are Holders (as

                                      A-5
<PAGE>
 
reflected in the Security Register at the close of business on the February 1
and August 1 immediately preceding the Interest Payment Date), in each case,
even if the Note is cancelled on registration of transfer, registration of
exchange, redemption or repurchase after such Regular Record Date.  With respect
to the payment of principal, the Company will make payment to the Holder that
surrenders this Note to a Paying Agent on or after August 15, 2006.

     The Company will pay principal, premium and Liquidated Damages, if any, and
interest in money of the United States that at the time of payment is legal
tender for payment of public and private debts at the office or agency of the
Company maintained for such purposes in the Borough of Manhattan, City of New
York.  The Company, at its option, may pay principal, premium and Liquidated
Damages, if any, and interest by its check payable in such money mailed to a
Holder's registered address (as reflected in the Security Register), provided
that payment by wire transfer of immediately available funds will be required
with respect to principal, premium and Liquidated Damages, if any, and interest
on all Global Notes and all other Notes the Holders of which shall have provided
wire transfer instructions to the Company or the Paying Agent.  If an Interest
Payment Date is a date other than a Business Day at a place of payment, payment
may be made on the next succeeding day that is a Business Day with the same
force and effect as if made on the day such payment was due and in the case of
such payment no interest shall accrue for the intervening period.

     (3)  Paying Agent and Registrar.  Initially, the Trustee will act as
          --------------------------                                     
authenticating agent, Paying Agent and Registrar.  The Company may change any
authenticating agent, Paying Agent or Registrar without notice.  The Company,
any Subsidiary or any Affiliate of any of them may act as Paying Agent,
Registrar or co-Registrar.

     (4)  Indenture; Limitations.  The Company issued the Notes under an
          ----------------------                                        
Indenture dated as of December 2, 1996 (the "Indenture"), between the Company
and Marine Midland Bank, as trustee (the "Trustee").  Capitalized terms herein
are used as defined in the Indenture unless otherwise indicated.  Reference is
made to the Indenture and the Trust Indenture Act for a full, complete and
detailed statement of the purposes for which the Notes are issued, the terms on
which the Notes are issued, a description of the security pledged and assigned
for payment of the Notes and the terms, provisions and conditions governing
payment of the Notes 

                                      A-6
<PAGE>
 
and the provisions, among others, with respect to the nature and extent of the
rights, duties and obligations of the Trustee, the Paying Agent, the Registrar,
the authenticating agent, Holders and the Company. The holder of this Note, by
acceptance of this Note, is deemed to have agreed and consented to the terms and
provisions of the Indenture. The terms of the Notes include those stated in the
Indenture and those made part of the Indenture by reference to the Trust
Indenture Act. The Notes are subject to all such terms, and Holders are referred
to the Indenture and the Trust Indenture Act for a statement of all such terms.
If any provision of this Note conflicts with the Indenture, the terms of the
Indenture control.

     The Notes are general unsecured obligations of the Company.  The Indenture
limits the original aggregate principal amount of the Notes to $250,000,000.

     (5)  Optional Redemption.  The Notes will be redeemable, at the Company's
          -------------------                                                 
option, in whole or in part, at any time or from time to time, on or after
August 15, 2001 and prior to maturity, upon not less than 30 nor more than 60
days' prior notice mailed by first class mail to each Holder's last address as
it appears in the Security Register, at the Redemption Prices (expressed in
percentages of principal amount) set forth below, plus accrued and unpaid
interest and Liquidated Damages, if any, to the Redemption Date (subject to the
right of Holders of record on the relevant Regular Record Date that is prior to
the Redemption Date to receive interest due on an Interest Payment Date), if
redeemed during the 12-month period commencing August 15, of the years set forth
below:

          Redemption Year               Price   
          ----------------           ----------- 
          2001                        105.81%
          2002                        103.88%
          2003                        101.94%
          2004 and thereafter         100.00%

     In addition, at any time prior to August 15, 1999, the Company may redeem
up to one-third of the Notes originally issued, at any time as a whole or from
time to time in part, with the proceeds of one or more Public Equity Offerings
or sales of Capital Stock (other than Redeemable Stock) to one or more Strategic
Equity Investors, each such Public Equity Offering or sale to Strategic 

                                      A-7
<PAGE>
 
Equity Investors resulting in Net Cash Proceeds of $50 million or more, at a
redemption price (expressed as a percentage of principal amount) of 111.625%,
plus accrued and unpaid interest and Liquidated Damages, if any, to the
Redemption Date, provided that after any such redemption at least two-thirds of
the aggregate principal amount of Notes originally outstanding remains
outstanding and each such redemption is effected not more than 60 days after the
consummation of such Public Equity Offering or sale to Strategic Equity
Investors.

     If less than all of the Notes are to be redeemed at any time, the Trustee
will select the Notes, or portions thereof, for redemption in compliance with
the requirements of the principal national securities exchange, if any, on which
the Notes are listed or, if the Notes are not listed on a national securities
exchange, on a pro rata basis, by lot or by such other method as the Trustee in
its sole discretion shall deem to be fair and appropriate.  Notes in
denominations larger than $1,000 may be redeemed in part.  Any notice mailed as
provided herein and in the Indenture will be conclusively presumed to have been
given whether or not actually received by any Holder.  On and after the
Redemption Date, interest ceases to accrue on Notes or portions of Notes called
for redemption, unless the Company defaults in the payment of the Redemption
Price.  A new Note in original amount equal to the unredeemed portion thereof
will be issued in the name of the Holder thereof upon cancellation of the
original Note.

     (6)  Repurchase upon Change of Control and Asset Sale.  The Company shall
          ------------------------------------------------                    
commence within 30 days of the occurrence of a Change of Control and consummate
an Offer to Purchase for all Notes then outstanding at a purchase price equal to
101% of the principal amount thereof, plus accrued and unpaid interest and
Liquidated Damages, if any, to the Payment Date.  The Notes may also be subject
to an Offer to Purchase in connection with an Asset Sale.  Any Note delivered
for payment of a purchase price shall be accompanied by an instrument in the
form of the Option of the Holder to Elect Purchase below.

     (7)  Denominations; Transfer; Exchange.  The Notes are in registered form

without coupons in denominations of $1,000 of principal amount and  multiples of
$1,000 in excess thereof.  A Holder may register the transfer or exchange of
Notes in accordance with the Indenture.  The Registrar may require a Holder,
among other things, to furnish appropriate endorsements and transfer documents
(including a certificate in the form of the Certificate to be Delivered upon

                                      A-8
<PAGE>
 
Exchange or Registration of Transfer of Securities below) and to pay any taxes,
fees and/or other governmental charges required by law or permitted by the
Indenture. The Registrar need not register the transfer or exchange of any Notes
selected for redemption. Also, it need not register the transfer or exchange of
any Notes for a period of 15 days before the day of the mailing of a notice of
redemption of Notes selected for redemption.

     (8)  Persons Deemed Owners.  A Holder shall be treated as the owner of a
          ---------------------                                              
Note for all purposes.

     (9)  Unclaimed Money.  If money for the payment of principal, premium and
          ---------------                                                     
Liquidated Damages, if any, or interest remains unclaimed for two years, the
Trustee and the Paying Agent will pay the money back to the Company at its
written request.  After that, Holders entitled to the money must look to the
Company for payment, unless applicable law designates another Person, and all
liability of the Trustee and such Paying Agent with respect to such money shall
cease.

     (10)  Defeasance and Discharge Prior to Redemption or Maturity.  If the
           --------------------------------------------------------         
Company deposits with the Trustee money or U.S. Government Obligations
sufficient to pay the then outstanding principal of, premium and Liquidated
Damages, if any, and accrued interest on the Notes to redemption or maturity,
and complies with certain other provisions of the Indenture relating thereto,
(i) the Company will be deemed to have paid and will be discharged from any and
all obligations in respect of the Notes or (ii) certain provisions set forth in
the Indenture will no longer be in effect with respect to the Notes.

     (11)  Amendment; Supplement; Waiver.  Subject to certain exceptions, the
           -----------------------------                                     
Indenture or the Notes may be amended or supplemented with the consent of the
Holders of at least a majority in aggregate principal amount of the Notes then
outstanding, and any existing default or compliance with any provision may be

change that does not adversely affect the rights of any Holder.

     (12)  Restrictive Covenants. The Indenture imposes certain limitations on
           ---------------------

     (13)  Successor Persons.  When a successor person or other entity assumes
           -----------------                                                  
all the obligations of its predecessor under the Notes and the Indenture, the
predecessor person will be released from those obligations.

     (14)  Defaults and Remedies.  An Event of Default is: (a) a default in
           ---------------------                                           
payment of principal or premium, if any, on the Notes; (b) default in the

continuing, the Trustee or the Holders of at least 25% in aggregate principal
amount of the Notes then outstanding may, and the Trustee at the request of such
Holders shall, declare all the Notes to be due and payable.  If a bankruptcy or
insolvency default with respect to the Company occurs and is continuing, the
Notes automatically become due and payable.  Holders may not enforce the
Indenture or the Notes, or take any action with respect to any Event of Default
under the Indenture, or to institute, appear in or defend any suit or other
proceeding with respect thereto, except as provided in the Indenture.  The
Trustee may require indemnity satisfactory to it before it enforces the
Indenture or the Notes.  Subject to certain 

                                     A-10
<PAGE>
 
limitations under the Indenture, Holders of at least a majority in principal
amount of the Notes then outstanding may direct in accordance with the
provisions of the Indenture the Trustee in its exercise of any trust or power,

available to the Trustee.

           -----------------------------                                      
its individual or any other capacity, may make loans to, accept deposits from
and perform services for the Company or its Affiliates and may otherwise deal
with the Company or its Affiliates as if it were not the Trustee.

     (16)  No Recourse Against Others.  No incorporator or any past, present or
           --------------------------                                          
future partner, shareholder, other equity holder, officer, director, employee or
controlling person as such, of the Company or of any successor Person shall have
any liability for any obligations of the Company under the Notes or the
Indenture or for any claim based on, in respect of or by reason of, such
obligations or their creation.  Each Holder by accepting a Note expressly waives
and releases all such liability.  The waiver and release are a condition of, and
part of the consideration for the issuance of the Notes.

     (17)  Authentication.  This Note shall not be entitled to any right or
           --------------

charge a copy of the Indenture.  Requests may be made to Omnipoint Corporation,

2.   Exchange Offer
     --------------

     (a) The Issuer agrees to file with the SEC as soon as practicable after the
Closing Date, but in no event later than the Filing Date, an offer to exchange
(the "Exchange Offer"), any and all of the Transfer Restricted Notes for a like

                                       4
<PAGE>
 
aggregate principal amount of debt securities of the Issuer (the "Exchange
Notes"), which Exchange Notes will be (i) substantially identical in all
material respects to the Notes, except that such Exchange Notes will not contain
terms with respect to transfer restrictions, (ii) entitled to the benefits of
the Indenture or a trust indenture which is identical to the Indenture (other
than such changes to the Indenture or any such identical trust indenture as are
necessary to comply with any requirements of the SEC to effect or maintain the
qualification thereof under the TIA), and which, in either case, has been
qualified under the TIA, and (iii) registered pursuant to an effective
Registration Statement in compliance with the Securities Act.  The Exchange
Offer will be registered pursuant to the Securities Act on an appropriate form
of Registration Statement (the "Exchange Offer Registration Statement"), and
will comply with all applicable tender offer rules and regulations promulgated
pursuant to the Exchange Act and shall be duly registered or qualified pursuant
to all applicable state securities or Blue Sky laws.  The Exchange Offer shall
not be subject to any condition, other than that the Exchange Offer does not
violate any applicable law, policy or interpretation of the staff of the SEC.
No securities shall be included in the Exchange Offer Registration Statement
other than the Exchange Notes.  The Issuer agrees to use its best efforts to (x)
cause the Exchange Offer Registration Statement to become effective pursuant to
the Securities Act on or before the Effectiveness Target Date; and (y) keep the
Exchange Offer open for not less than 20 Business Days (or such longer period
required by applicable law), after the date that the notice of the Exchange
Offer referred to below is mailed to Holders.  Each Holder who participates in
the Exchange Offer will be required to represent that any Exchange Notes
received by it will be acquired in the ordinary course of its business, that at
the time of the consummation of the Exchange Offer such Holder will have no
arrangement or understanding with any person to participate in the distribution
of the Exchange Notes, and that such Holder is not an "affiliate" of the Issuer
within the meaning of Rule 405 of the Securities Act (or that if it is such an
affiliate, it will comply with the registration and prospectus delivery
requirements of the Securities Act to the extent applicable).  Each Holder that
is not a Participating Broker-Dealer will be required to represent that it is
not engaged in, and does not intend to engage in, the distribution of the
Exchange Notes.  Each Holder that (i) is a Participating Broker-Dealer and (ii)
will receive Exchange Notes for its own account in exchange for the Transfer
Restricted Notes that it acquired as the result of market-making or other
trading activities will be required to acknowledge that it will deliver a
Prospectus as required by law in connection with any resale of such Exchange
Notes.  Upon consummation of the Ex-

                                       5
<PAGE>
 
change Offer in accordance with this Agreement, the Issuer shall have no further
obligation to register Transfer Restricted Notes pursuant to Section 3 of this
Agreement.

     (b) The Issuer shall include within the Prospectus contained in the
Exchange Offer Registration Statement a section entitled "Plan of Distribution,"
acceptable to the Initial Purchasers, which shall contain a summary statement of
the positions taken or policies made by the staff of the SEC with respect to the
potential "underwriter" status of any broker-dealer that is the beneficial owner
(as defined in Rule 13d-3 under the Exchange Act), of Exchange Notes received by
such broker-dealer in the Exchange Offer (a "Participating Broker-Dealer").
Such "Plan of Distribution" section shall also allow the use of the Prospectus
by all persons subject to the prospectus delivery requirements of the Securities
Act, including all Participating Broker-Dealers, and include a statement
describing the means by which Participating Broker-Dealers may resell the
Exchange Notes.

     The Issuer shall use its best efforts to keep the Exchange Offer
Registration Statement effective and to amend and supplement the Prospectus
contained therein, in order to permit such Prospectus to be lawfully delivered
by all persons subject to the prospectus delivery requirements of the Securities
Act for such period of time as such persons must comply with such requirements
in order to resell the Exchange Notes; provided that such period shall not
                                       --------                           
exceed 180 days after consummation of the Exchange Offer (or such longer period
if extended pursuant to the last paragraph of Section 5 hereof) (the "Applicable
Period").

     In connection with the Exchange Offer, the Issuer shall:

          (i)    mail as promptly as practicable to each Holder a copy of the
     Prospectus forming part of the Exchange Offer Registration Statement,
     together with an appropriate letter of transmittal and related documents;

          (ii)   utilize the services of a depositary for the Exchange Offer
     with an address in the Borough of Manhattan, The City of New York; and

          (iii)  permit Holders to withdraw tendered Notes at any time prior to
     the close of business, New York time, on the last Business Day on which the
     Exchange Offer shall remain open by sending to the institution and at 

                                       6
<PAGE>
 
     the address (located in the Borough of Manhattan, The City of New York)
     specified in the notice, a telegram, telex, facsimile transmission or
     letter setting forth the name of such Holder, the principal amount of
     Transfer Restricted Securities delivered for exchange and a statement that
     such Holder is withdrawing his or her election to have such Transfer
     Restricted Securities exchanged.

     As soon as practicable after the close of the Exchange Offer, the Issuer
shall:

          (i)    accept for exchange all Notes tendered and not validly
     withdrawn pursuant to the Exchange Offer;

          (ii)   deliver, or cause to be delivered, to the Trustee for
     cancellation all Notes so accepted for exchange; and

          (iii)  cause the Trustee to authenticate and deliver promptly to each
     Holder of Notes, Exchange Notes equal in principal amount to the Notes of
     such Holder so accepted for exchange.

     (c) If (1) prior to the consummation of the Exchange Offer, applicable
interpretations of the staff of the SEC do not permit the Issuer to effect the
Exchange Offer, or (2) if for any other reason the Exchange Offer is not
consummated within 135 days of the Closing Date, then the Issuer shall promptly
deliver to the Holders and the Trustee written notice thereof (the "Shelf
Notice"), and the Issuer shall file a Registration Statement pursuant to Section
3 hereof.  Following the delivery of a Shelf Notice to the Holders of Transfer
Restricted Notes, the Issuer shall not have any further obligation to conduct
the Exchange Offer pursuant to this Section 2, provided, that the Issuer shall
                                               --------                       
have the right, nonetheless, to proceed to consummate the Exchange Offer
notwithstanding its obligations pursuant to this Section 2(c) (and, upon such
consummation, its obligation to consummate a Shelf Registration shall
terminate).

3.   Shelf Registration
     ------------------

     If the Issuer is required to deliver a Shelf Notice as contemplated by
Section 2(c) hereof, then:

                                       7
<PAGE>
 
     (a) Shelf Registration.  The Issuer shall prepare and file with the SEC, as
         ------------------                                                     
promptly as practicable following the Shelf Notice, a Registration Statement for
an offering to be made on a continuous basis pursuant to Rule 415 covering all
of the Transfer Restricted Notes (the "Shelf Registration").  The Shelf
Registration shall be on Form S-1 or another appropriate form permitting
registration of the Transfer Restricted Notes for resale by the Holders in the
manner or manners reasonably designated by them (including, without limitation,
one or more underwritten offerings).  The Issuer shall not permit any securities
other than the Transfer Restricted Notes to be included in the Shelf
Registration.  The Issuer shall use its best efforts, as described in Section
5(b) hereof, to cause the Shelf Registration to be declared effective pursuant
to the Securities Act as promptly as practicable after the filing of such Shelf
Registration and to keep the Shelf Registration continuously effective under the
Securities Act until the earlier of (i) the date which is 36 months after the
Closing Date, (ii) the date that all Transfer Restricted Notes covered by the
Shelf Registration have been sold in the manner set forth and as contemplated in
the Shelf Registration or (iii) the date that there ceases to be outstanding any
Transfer Restricted Notes (the "Effectiveness Period").

     (b) Supplements and Amendments.  The Issuer shall use its best efforts to
         --------------------------                                           
keep the Shelf Registration continuously effective by supplementing and amending
the Shelf Registration if required by the rules, regulations or instructions
applicable to the registration form used for such Shelf Registration, if
required by the Securities Act, or if reasonably requested by the Holders of a
majority in aggregate principal amount of the Transfer Restricted Notes covered
by such Registration Statement or by any underwriter of such Transfer Restricted
Notes.

4.   Liquidated Damages
     ------------------

     (a) The Issuer and the Initial Purchasers agree that the Holders of
Transfer Restricted Notes will suffer damages if the Issuer fails to fulfill its
obligations pursuant to Section 2 or Section 3 hereof and that it would not be
possible to ascertain the extent of such damages.  Accordingly, in the event of
such failure by the Issuer to fulfill such obligations, the Issuer hereby agrees
to pay liquidated damages ("Liquidated Damages") to each Holder of Transfer
Restricted Notes under the circumstances and to the extent set forth below:

                                       8
<PAGE>
 
          (i)    if neither the Exchange Offer Registration Statement nor the
     Shelf Registration has been filed with the SEC on or prior to the Filing
     Date; or

          (ii)   if neither the Exchange Offer Registration Statement nor the
     Shelf Registration is declared effective by the SEC on or prior to the
     Effectiveness Target Date; or

          (iii)  if an Exchange Offer Registration Statement is declared
     effective by the SEC, and on or prior to 45 days following the earlier of
     (A) the effectiveness thereof or (B) the Effectiveness Target Date, the
     Issuer has not exchanged Exchange Notes for all Notes validly tendered in
     accordance with the terms of the Exchange Offer; or

          (iv)   the Shelf Registration has been declared effective by the SEC
     and such Shelf Registration ceases to be effective or usable at any time
     during the Effectiveness Period, without being succeeded on the same day
     immediately by a post-effective amendment to such Shelf Registration that
     cures such failure and that is itself immediately declared effective on the
     same day;

          (any of the foregoing, a "Registration Default"), then, with respect
to the first 90-day period following such Registration Default, the Issuer shall
pay to each Holder of Transfer Restricted Notes Liquidated Damages in an amount
equal to $0.05 per week per $1,000 principal amount of Transfer Restricted Notes
held by such Holder for each week or portion thereof that the Registration
Default continues.  The amount of such Liquidated Damages will increase by an
additional $0.05 per week per $1,000 principal amount of Transfer Restricted
Notes with respect to each subsequent 90-day period until all Registration
Defaults have been cured; provided, however, that Liquidated Damages shall not
                          --------  -------                                   
at any time exceed $0.50 per week per $1,000 principal amount of Transfer
Restricted Notes (regardless of whether one or more than one Registration
Defaults has occurred and is continuing).  Following the cure of all
Registration Defaults relating to any Transfer Restricted Notes, the accrual of
Liquidated Damages with respect to such Transfer Restricted Notes will cease.  A
Registration Default under clause (i) above shall be cured on the date that
either the Exchange Offer Registration Statement or the Shelf Registration is
filed with the SEC; a Registration Default under 

                                       9
<PAGE>
 
clause (ii) above shall be cured on the date that either the Exchange Offer
Registration Statement or the Shelf Registration is declared effective by the
SEC; a Registration Default under clause (iii) above shall be cured on the
earlier of the date (A) the Exchange Offer is consummated or (B) a Shelf
Registration is declared effective; and a Registration Default under clause (iv)
above shall be cured on the earlier of (A) the date that the post-effective
amendment curing the deficiency in the Shelf Registration is declared effective
or (B) the Effectiveness Period expires.

     (b) The Issuer shall notify the Trustee within one Business Day after each
and every date on which a Registration Default first occurs.  Liquidated Damages
shall be paid by the Issuer to the Holders by wire transfer of immediately
available funds to the accounts specified by them or by mailing checks to their
respective addresses as such addresses appear in the Security Register if no
such accounts have been specified on or before the semi-annual interest payment
date provided in the Indenture and on each payment date provided in the
Indenture including, without limitation, whether upon redemption, maturity (by
acceleration or otherwise), purchase upon a Change of Control or purchase upon a
sale of assets.  Each obligation to pay Liquidated Damages shall be deemed to
commence accruing on the date of the applicable Registration Default and to
cease accruing when all Registration Defaults have been cured.  In no event
shall the Issuer pay Liquidated Damages in excess of the applicable maximum
weekly amount set forth above, regardless of whether one or multiple
Registration Defaults exist.

     (c) The parties hereto agree that the Liquidated Damages provided for in
this Section 4 constitute a reasonable estimate of the damages that will be
suffered by Holders by reason of the failure to file the Exchange Offer

Restricted Notes 

                                      10

(as applicable), in accordance with the intended method or methods of
disposition thereof, and pursuant thereto the Issuer shall:

     (a) prepare and file with the SEC a Registration Statement or Registration
Statements as prescribed by Section 2 or Section 3 hereof, and use its best
efforts to cause such Registration Statement to become effective and remain
effective as provided herein; provided that, if (1) such filing is pursuant to
                              --------                                        
Section 3 hereof, or (2) a Prospectus contained in an Exchange Offer
Registration Statement filed pursuant to Section 2 hereof is required to be
delivered under the Securities Act by any Participating Broker-Dealer who seeks
to sell Exchange Notes during the Applicable Period, before filing any
Registration Statement or Prospectus or any amendments or supplements thereto,
the Issuer shall furnish to and afford the Holders of the Transfer Restricted
Notes and each such Participating Broker-Dealer, as the case may be, covered by
such Registration Statement, their counsel and the managing underwriters, if
any, a reasonable opportunity to review copies of all such documents (including
copies of any documents to be incorporated by reference therein and all exhibits
thereto), proposed to be filed (at least 3 Business Days prior to such filing,
or such later date as is reasonable under the circumstances).  The Issuer shall
not file any Registration Statement or Prospectus or any amendments or
supplements thereto in respect of which the Holders, pursuant to this Agreement,
must be afforded an opportunity to review prior to the filing of such document,
if the Holders of a majority in aggregate principal amount of the Transfer
Restricted Notes covered by such Registration Statement, or such Participating
Broker-Dealer, as the case may be, their counsel, or the managing underwriters,
if any, shall reasonably object on a timely basis (except that documents filed
as exhibits that are incorporated by reference or deemed to be incorporated by
reference shall not be subject to such objections);

     (b) prepare and file with the SEC such amendments and post-effective
amendments to each Shelf Registration or Exchange Offer Registration Statement,
as the case may be, as may be necessary to keep such Registration Statement
continuously effective for the Effectiveness Period or the Applicable Period, as
the case may be, or such shorter period as will terminate when all Transfer
Restricted Notes covered by such Registration Statement have been sold; cause
the related Prospectus to be supplemented by any required prospectus supplement,
and as so supplemented to be filed pursuant to Rule 424 (or any similar
provisions then in force), under the Securities Act; and comply with the
provisions of the Securities 

                                      11
<PAGE>
 
Act, the Exchange Act and the rules and regulations of the SEC promulgated
thereunder with respect to the disposition of all securities covered by such
Registration Statement, as so amended, or in such Prospectus, as so
supplemented, and with respect to the subsequent resale of any Notes being sold
by a Participating Broker-Dealer covered by any such Prospectus; the Issuer
shall be deemed not to have used its best efforts to keep a Registration
Statement effective during the Applicable Period if it voluntarily takes any
action that would result in selling Holders of the Transfer Restricted Notes
covered thereby or Participating Broker-Dealers seeking to sell Exchange Notes
not being able to sell such Transfer Restricted Notes or such Exchange Notes
during that period, unless (i) such action is required by applicable law, or
(ii) such action is taken by it in good faith and for valid business reasons
(not including avoidance of its obligations hereunder), including the
acquisition or divestiture of assets;

     (c) if (1) a Shelf Registration is filed pursuant to Section 3 hereof, or
(2) a Prospectus contained in an Exchange Offer Registration Statement filed

the Applicable Period, notify the selling Holders of Transfer Restricted Notes,
or each known Participating Broker-Dealer, as the case may be, their counsel and
the managing underwriters, if any, promptly and confirm such notice in writing,
(i) when a Prospectus, any prospectus supplement or post-effective amendment has
been filed, and, with respect to a Registration Statement or any post-effective
amendment, when the same has become effective (including in such notice a
written statement that any Holder may, upon request, obtain, without charge, one
conformed copy of such Registration Statement or post-effective amendment
including financial statements and schedules, documents incorporated or deemed
to be incorporated by reference and exhibits), (ii) of the issuance by the SEC
of any stop order suspending the effectiveness of a Registration Statement or of
any order preventing or suspending the use of any preliminary prospectus or the
initiation of any proceedings for that purpose, (iii) if at any time when a
Prospectus is required by the Securities Act to be delivered in connection with
sales of the Transfer Restricted Notes the representations and warranties of the
Issuer contained in any agreement (including any underwriting agreement),
contemplated by Section 5(l) hereof cease to be true and correct, (iv) of the
receipt by the Issuer of any notification with respect to the suspension of the
qualification or exemption from qualification of a Registration Statement or any
of the Transfer Restricted Notes or the 

                                      12

Exchange Notes to be sold by any Participating Broker-Dealer for offer or sale
in any jurisdiction, or the initiation of any proceeding for such purpose, (v)
of the happening of any event or any information becoming known that makes any
statement made in such Registration Statement or related Prospectus or any
document incorporated or deemed to be incorporated therein by reference untrue
in any material respect or that requires the making of any changes in such
Registration Statement, Prospectus or documents so that, in the case of the
Registration Statement, it will not contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein not misleading, and that in the case of
the Prospectus, it will not contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading, and (vi) of the Issuer's reasonable determination that a
post-effective amendment to a Registration Statement would be appropriate;

(2) a Prospectus contained in an Exchange Offer Registration Statement filed
pursuant to Section 2 hereof is required to be delivered under the Securities
Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during
the Applicable Period, use its best efforts to prevent the issuance of any order
suspending the effectiveness of a Registration Statement or of any order
preventing or suspending the use of a Prospectus or suspending the qualification
(or exemption from qualification), of any of the Transfer Restricted Notes or
the Exchange Notes (as applicable), to be sold by any Participating Broker-
Dealer, for sale in any jurisdiction, and, if any such order is issued, to use
its best efforts to obtain the withdrawal of any such order at the earliest
possible moment;

     (e) if a Shelf Registration is filed pursuant to Section 3 hereof and if
requested by the managing underwriters, if any, or the Holders of a majority in
aggregate principal amount of the Transfer Restricted Notes being sold in
connection with an underwritten offering, (i) promptly incorporate in a
prospectus supplement or post-effective amendment such information relating to
underwriters, if any, any Holder of Transfer Restricted Notes or the plan of
distribution of the Transfer Restricted Notes as the managing underwriter, if
any, or such Holders may reasonably request to be included therein, (ii) make
all required filings of such prospectus supplement or such post-effective
amendment as soon as practicable 

                                      13

after the Issuer has received notification of the matters to be incorporated in
such prospectus supplement or post-effective amendment pursuant to clause (i),
and (iii) supplement or make amendments to such Registration Statement with such
information as is required in connection with any request made pursuant to
clause (i);

     (f) if (1) a Shelf Registration is filed pursuant to Section 3 hereof, or

pursuant to Section 2 hereof is required to be delivered under the Securities
Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during
the Applicable Period, furnish to each selling Holder of Transfer Restricted
Notes and to each such Participating Broker-Dealer who so requests and to
counsel and each managing underwriter, if any, without charge, one conformed
copy of the Registration Statement or Registration Statements and each post-
effective amendment thereto, including financial statements and schedules, and,
if requested, all documents incorporated or deemed to be incorporated therein by
reference and all exhibits;

     (g) if (1) a Shelf Registration is filed pursuant to Section 3 hereof, or

Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during

Notes, or each such Participating Broker-Dealer, as the case may be, its
counsel, and the underwriters, if any, without charge, as many copies of the
Prospectus or Prospectuses (including each form of preliminary Prospectus), and
each amendment or supplement thereto and any documents incorporated by reference
therein, as such Persons may reasonably request; and, subject to the last
paragraph of this Section 5 hereof, the Issuer hereby consents to the use of
such Prospectus and each amendment or supplement thereto by each of the selling
Holders of Transfer Restricted Notes or each such Participating Broker-Dealer,
as the case may be, and their underwriters or agents, if any, and dealers, if
any, in connection with the offering and sale of the Transfer Restricted Notes

(or exemption from such registration or qualification), of such Transfer
Restricted Notes for offer and sale under the securities or Blue Sky laws of

such jurisdictions of the Exchange Notes held by Participating Broker-Dealers or

Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during

reasonably requested by any such Inspector in connection with such Registration
Statement;

     (n) provide an indenture trustee for the Transfer Restricted Notes or the
Exchange Notes, as the case may be, and cause the Indenture to be qualified

furnish to the Issuer such information regarding such seller or Participating
Broker-Dealer and the distribution of such Transfer Restricted Notes or Exchange

Purchasers, each Holder of Transfer Restricted Notes, each initial Holder of
Exchange Notes and each Participating Broker-Dealer, (ii) each person, if any,
who controls (within the meaning of Section 15 of the Securities Act or Section
20 of the Exchange Act), any such Person (any of the persons referred to in this
clause (ii) being hereinafter referred to as a "controlling person"), and (iii)
the respective officers, directors, partners, employees, representatives and
agents of any of such Person or any controlling person (any person referred to
in clause (i), (ii) or (iii) may hereinafter be referred to as an "Indemnified
Person"), to the fullest extent lawful, from and against any and all losses,
claims, damages, judgments, actions, expenses, and other liabilities (the
"Liabilities"), including without limitation and as incurred, reimbursement of
all reasonable costs of investigating, preparing, pursuing or defending any
claim or action, or any investigation or proceeding by any governmental agency
or body, commenced or threatened, including the reasonable fees and expenses of
counsel to any Indemnified Person, directly or indirectly related to, based
upon, arising out of or in connection with any untrue statement or alleged
untrue statement of a material fact contained in any Registration Statement or
Prospectus (as amended or supplemented if the Issuer shall have furnished to
such Indemnified Person any amendments or supplements thereto), or any
preliminary prospectus, or any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading, except insofar as such Liabilities arise out of or are based upon
(i) any untrue statement or omission or alleged untrue statement or omission
made in reliance upon and in conformity with information relating to any
Indemnified Person furnished to the Issuer or any underwriter in writing by such
Indemnified Person expressly for use therein, or (ii) any untrue statement
contained in or omission from a preliminary prospectus if a copy of the
Prospectus (as then amended or supplemented, if the Issuer shall have furnished
to or on behalf of the Holder participating in the distribution relating to the
relevant Registration Statement any amendments or supplements thereto) was not
sent or given by or on behalf of such Holder to the person asserting any such
Liabilities who purchased Notes, if such Prospectus (or Prospectus as amended or
supplemented), is required by law at or prior to the written confirmation of the
sale of such Notes to such person and the untrue statement contained in or
omission from such preliminary prospectus was completely corrected in the
Prospectus (or the Prospectus as amended or supplemented). The Issuer shall
notify the Holders promptly of the institution, threat or assertion of any

                                      21
<PAGE>
 
claim, proceeding (including any governmental investigation), or litigation of
which it shall have become aware in connection with the matters addressed by
this Agreement which involves the Issuer, any subsidiary of the Issuer or an
Indemnified Person.

     In connection with any Registration Statement in which a Holder of Transfer
Restricted Notes is participating, such Holder of Transfer Restricted Notes
agrees, severally and not jointly, to indemnify and hold harmless the Issuer,
each person who controls the Issuer within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act and the respective partners,
directors, officers, representatives, employees and agents of such person or
controlling person to the same extent as the foregoing indemnity from the Issuer
to each Indemnified Person, but only with reference to information relating to
such Indemnified Person furnished to the Issuer in writing by such Indemnified
Person expressly for use in any Registration Statement or Prospectus, any
amendment or supplement thereto, or any preliminary Prospectus.  The liability
of any Indemnified Person pursuant to this paragraph shall in no event exceed
the net proceeds received by such Indemnified Person from sales of Transfer
Restricted Notes giving rise to such obligations.

     If any suit, action, proceeding (including any governmental or regulatory
investigation), claim or demand shall be brought or asserted against any person
in respect of which indemnity may be sought pursuant to either of the two
preceding paragraphs, such person (the "Indemnified Party"), shall promptly
notify the person against whom such indemnity may be sought (the "Indemnifying
Person"), in writing, and the Indemnifying Person, upon request of the
Indemnified Party, shall retain counsel reasonably satisfactory to the
Indemnified Party to represent the Indemnified Party and any others the
Indemnifying Person may reasonably designate in such proceeding and shall pay
the reasonable fees and expenses actually incurred by such counsel related to
such proceeding.  In any such proceeding, any Indemnified Party shall have the
right to retain its own counsel, but the fees and expenses of such counsel shall
be at the expense of such Indemnified Party, unless (i) the Indemnifying Person
and the Indemnified Party shall have mutually agreed in writing to the contrary,
(ii) the Indemnifying Person failed promptly to assume the defense and employ
counsel reasonably satisfactory to the Indemnified Party or (iii) the named
parties to any such action (including any impleaded parties), include both such
Indemnified Party and the Indemnifying Person, or any 

                                      22
<PAGE>
 
affiliate of the Indemnifying Person, and such Indemnified Party shall have been
reasonably advised by counsel that, either (x) there may be one or more legal
defenses available to it which are different from or additional to those
available to the Indemnifying Person or such affiliate of the Indemnifying
Person or (y) a conflict may exist between such Indemnified Party and the
Indemnifying Person or such affiliate of the Indemnifying Person (in which case
the Indemnifying Person shall not have the right to assume the defense of such
action on behalf of such Indemnified Party, it being understood, however, that
the Indemnifying Person shall not, in connection with any one such action or
separate but substantially similar or related actions in the same jurisdiction
arising out of the same general allegations or circumstances, be liable for the
fees and expenses of more than one separate firm of attorneys (in addition to
any local counsel), for all such indemnified parties, which firm shall be
designated in writing by those indemnified parties who sold a majority in
outstanding aggregate principal amount of Transfer Restricted Notes sold by all
such indemnified parties and any such separate firm for the Issuer, its
directors, its officers and such control persons of the Issuer as shall be
designated in writing by the Issuer. The Indemnifying Person shall not be liable
for any settlement of any proceeding effected without its written consent, which
consent shall not be unreasonably withheld, but if settled with such consent or
if there be a final judgment for the plaintiff, the Indemnifying Person agrees
to indemnify any Indemnified Party from and against any loss or liability by
reason of such settlement or judgment. No Indemnifying Person shall, without the
prior written consent of the Indemnified Party, effect any settlement of any
pending or threatened proceeding in respect of which any Indemnified Party is or
could have been a party and indemnity could have been sought hereunder by such
Indemnified Party, unless such settlement includes an unconditional release of
such Indemnified Party from all liability on claims that are the subject matter
of such proceeding.

     If the indemnification provided for in the first and second paragraphs of
this Section 7 is unavailable to an Indemnified Party in respect of any
Liabilities referred to therein (other than by reason of the exceptions provided
therein), then each Indemnifying Person under such paragraphs, in lieu of
indemnifying such Indemnified Party thereunder, shall contribute to the amount
paid or payable by such Indemnified Party as a result of such Liabilities (i) in
such proportion as is appropriate to reflect the relative benefits of the
Indemnified Party on the one hand and the Indemnifying Person(s) on the other in
connection with the statements or omissions that resulted in such Liabilities,
or (ii) if the allocation provided by 

                                      23
<PAGE>
 
clause (i) above is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of the Indemnifying Person(s) and the
Indemnified Party, as well as any other relevant equitable considerations. The
relative fault of the Issuer on the one hand and any Indemnified Persons on the
other shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Issuer
or by such Indemnified Persons and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission.

     The parties agree that it would not be just and equitable if contribution
pursuant to this Section 7 were determined by pro rata allocation (even if such
                                              --- ----                         
indemnified parties were treated as one entity for such purpose), or by any
other method of allocation that does not take account of the equitable
considerations referred to in the immediately preceding paragraph.  The amount
paid or payable by an Indemnified Party as a result of any Liabilities referred
to in the immediately preceding paragraph shall be deemed to include, subject to
the limitations set forth above, any reasonable legal or other expenses actually
incurred by such Indemnified Party in connection with investigating or defending
any such action or claim.  Notwithstanding the provisions of this Section 7, in
no event shall an Indemnified Person be required to contribute any amount in
excess of the amount by which proceeds received by such Indemnified Person from
sales of Transfer Restricted Notes or Exchange Notes exceeds the amount of any
damages that such Indemnified Person has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission.  No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act), shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation.

     The indemnity and contribution agreements contained in this Section 7 will
be in addition to any liability which the indemnifying parties may otherwise
have to the indemnified parties referred to above.  The Indemnified Persons'
obligations to contribute pursuant to this Section 7 are several in proportion
to the respective principal amount of Notes sold by each of the Indemnified
Persons hereunder and not joint.

8.   Rules 144 and 144A
     ------------------

     The Issuer covenants that it will file the reports required to be filed by
it pursuant to the Securities Act and the Exchange Act and the rules and
regulations adopted by the SEC thereunder in a timely manner and, if at any time
the Issuer is not required to file such reports, it will, upon the request of
any Holder of Transfer Restricted Notes, make available information required by
Rule 144 and Rule 144A under the Securities Act in order to permit sales
pursuant to Rule 144 and Rule 144A.  The Issuer further covenants that it will
take such further action as any Holder of Transfer Restricted Notes may
reasonably request, all to the extent required from time to time to enable such
Holder to sell Transfer Restricted Notes without registration under the
Securities Act within the limitation of the exemptions provided by (a) Rule 144
and Rule 144A or (b) any similar rule or regulation hereafter adopted by the
SEC.

9.   Underwritten Registrations
     --------------------------

     (a) If any of the Transfer Restricted Notes covered by any Shelf
Registration are to be sold in an underwritten offering, the investment banker
or investment bankers and manager or managers that will manage the offering will
be selected by the Holders of a majority in aggregate principal amount of such
Transfer Restricted Notes included in such offering and shall be reasonably
acceptable to the Issuer.

     No Holder of Transfer Restricted Notes may participate in any underwritten
registration hereunder, unless such Holder (a) agrees to sell such Holder's
Transfer Restricted Notes on the basis provided in any underwriting arrangements
approved by the Persons entitled hereunder to approve such arrangements and (b)
completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents required under the terms of such
underwriting arrangements.

     (b) Each Holder of Transfer Restricted Notes agrees, if requested (pursuant
to a timely written notice), by the managing underwriters in an underwritten
offering or by a placement agent in a private offering of the Issuer's debt
securities, not to effect any private sale or distribution (including a sale
pursuant to Rule 144(k) or Rule 144A under the Securities Act, but excluding
non-public sales 

                                      25
<PAGE>
 
to any of its affiliates, officers, directors, employees and controlling
persons), of any of the Notes except pursuant to an Exchange Offer, during the
period beginning 10 days prior to, and ending 90 days after, the closing date of
the underwritten offering.

     The foregoing provisions shall not apply to any Holder of Transfer
Restricted Notes if such Holder is prevented by applicable statute or regulation
from entering into any such agreement.

10.  Miscellaneous
     -------------

     (a) Remedies.  In the event of a breach by the Issuer of any of its
         --------                                                       
obligations under this Agreement, each Holder of Transfer Restricted Notes and
each Participating Broker-Dealer holding Exchange Notes, in addition to being
entitled to exercise all rights provided herein, in the Indenture or, in the
case of the Initial Purchasers, in the Purchase Agreement, or granted by law,
including recovery of damages, will be entitled to specific performance of its
rights under this Agreement.  Subject to Section 4, the Issuer agrees that
monetary damages would not be adequate compensation for any loss incurred by
reason of a breach by it of any of the provisions of this Agreement and hereby
further agrees that, in the event of any action for specific performance in
respect of such breach, it shall waive the defense that a remedy at law would be
adequate.

     (b) Amendments and Waivers.  The provisions of this Agreement, including
         ----------------------                                              
the provisions of this sentence, may not be amended, modified or supplemented,
and waivers or consents to or departures from the provisions hereof may not be
given, unless the Issuer has obtained the written consent of holders of at least
a majority of the then outstanding aggregate principal amount of Transfer
Restricted Notes and Exchange Notes held by Participating Broker-Dealers taken
as one class.  Notwithstanding the foregoing, a waiver or consent to or
departure from the provisions hereof with respect to a matter that relates
exclusively to the rights of Holders and Participating Broker-Dealers holding
Exchange Notes whose securities are being sold pursuant to a Registration
Statement and that does not directly or indirectly affect, impair, limit or
compromise the rights of other Holders and Participating Broker-Dealers holding
Exchange Notes may be given by holders of at least a majority in aggregate
principal amount of the Transfer Restricted Notes and Exchange Notes held by
Participating Broker-Dealers being sold by such Holders and Participating
Broker-Dealers pursuant to such Registra-

     Copies of all such notices, demands or other communications shall be
concurrently delivered by the Person giving the same to the Trustee under the
Indenture at the address specified in such Indenture.

     (d) Successors and Assigns.  This Agreement shall inure to the benefit of
         ----------------------

including, without limitation and without the need for an express assignment,
subsequent Holders of Transfer Restricted Notes.  The Issuer agrees that the

hereunder by the Initial Purchasers and the Issuer, and each Holder and
Participating Broker-Dealer shall have the right to enforce such agreements
directly to the extent it deems such enforcement necessary or advisable to
protect its rights hereunder.

PROCEEDING BROUGHT IN ANY SUCH COURT AND ANY CLAIM THAT ANY SUCH SUIT, ACTION OR
PROCEEDING BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.

                     11 5/8% Series A Senior Note due 2006



     (1)  Principal and Interest.  The Company will pay the principal of this
          ----------------------                                             
Note on August 15, 2006.

     The Company promises to pay interest on the principal amount of this Note
on each Interest Payment Date, as set forth below, at the rate per annum shown
above.

     Interest will be payable semiannually in arrears (to the holders of record
of the Notes, as reflected in the Security Register at the close of business on
the February 1 or August 1 immediately preceding the Interest Payment Date) on
each Interest Payment Date, commencing February 15, 1997.

     Interest on the Notes will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from December 2, 1996;
provided that, if there is no existing default in the payment of interest and if
this Note is authenticated between a Regular Record Date referred to on the face
hereof and the next succeeding Interest Payment Date, interest shall accrue from
such Interest Payment Date.  Interest will be computed on the basis of a 360-day
year of twelve 30-day months.

     The Company shall pay interest on overdue principal and premium and
Liquidated Damages, if any, and interest on overdue installments of interest, to
the extent lawful, at the rate borne by the Notes.

     (2)  Method of Payment.  The Company will pay interest (except defaulted
          -----------------                                                  
interest) on the principal amount of the Notes as provided above and Liquidated
Damages on each February 15 and August 15 to the persons who are Holders (as
reflected in the Security Register at the close of business on the February 1
and August 1 immediately preceding the Interest Payment Date), in each case,
even if the Note is cancelled on registration of transfer, registration of
exchange, redemption or repurchase after such Regular Record Date.  With respect
to the payment of principal, the Company will make payment to the Holder that
surrenders this Note to a Paying Agent on or after August 15, 2006.

     The Company will pay principal, premium and Liquidated Damages, if any, and
interest in money of the United States that at the time of payment is legal
tender for payment of public and private debts at the office or agency of the
Company maintained for such purposes in the Borough of Manhattan, City of New
York.  The Company, at its option, may pay principal, premium and Liquidated
Damages, if any, and interest by its check payable in such money mailed to a
Holder's registered address (as reflected in the Security Register), provided
that payment by wire transfer of 

                                      A-4
<PAGE>
 
immediately available funds will be required with respect to principal, premium
and Liquidated Damages, if any, and interest on all Global Notes and all other
Notes the Holders of which shall have provided wire transfer instructions to the
Company or the Paying Agent. If an Interest Payment Date is a date other than a
Business Day at a place of payment, payment may be made on the next succeeding
day that is a Business Day with the same force and effect as if made on the day
such payment was due and in the case of such payment no interest shall accrue
for the intervening period.

     (3)  Paying Agent and Registrar.  Initially, the Trustee will act as
          --------------------------                                     
authenticating agent, Paying Agent and Registrar.  The Company may change any
authenticating agent, Paying Agent or Registrar without notice.  The Company,
any Subsidiary or any Affiliate of any of them may act as Paying Agent,
Registrar or co-Registrar.

     (4)  Indenture; Limitations.  The Company issued the Notes under an
          ----------------------                                        
Indenture dated as of December 2, 1996 (the "Indenture"), between the Company
and Marine Midland Bank, as trustee (the "Trustee").  Capitalized terms herein
are used as defined in the Indenture unless otherwise indicated.  Reference is
made to the Indenture and the Trust Indenture Act for a full, complete and
detailed statement of the purposes for which the Notes are issued, the terms on
which the Notes are issued, a description of the security pledged and assigned
for payment of the Notes and the terms, provisions and conditions governing
payment of the Notes and the provisions, among others, with respect to the
nature and extent of the rights, duties and obligations of the Trustee, the
Paying Agent, the Registrar, the authenticating agent, Holders and the Company.
The holder of this Note, by acceptance of this Note, is deemed to have agreed
and consented to the terms and provisions of the Indenture.  The terms of the
Notes include those stated in the Indenture and those made part of the Indenture
by reference to the Trust Indenture Act.  The Notes are subject to all such
terms, and Holders are referred to the Indenture and the Trust Indenture Act for
a statement of all such terms.  If any provision of this Note conflicts with the
Indenture, the terms of the Indenture control.

     The Notes are general unsecured obligations of the Company.  The Indenture
limits the original aggregate principal amount of the Notes to $250,000,000.

     (5)  Optional Redemption.  The Notes will be redeemable, at the Company's
          -------------------                                                 
option, in whole or in part, at any time or from time to time, on or after
August 15, 2001 and prior to maturity, upon not less than 30 nor more than 60
days' prior notice mailed by first class mail to each Holder's last address as
it appears in the Security Register, at the Redemption Prices (expressed in
percentages of principal amount) set forth below, plus accrued and unpaid
interest and Liquidated Damages, if any, to the Redemption Date (subject to the
right of Holders of record on the relevant Regular Record Date that is prior to
the Redemption Date to receive interest due on an Interest Payment Date), if
redeemed during the 12-month period commencing August 15, of the years set forth
below:

          Redemption Year               Price 
          ----------------           ----------- 
          2001                         105.81%
          2002                         103.88%
          2003                         101.94%
          2004 and thereafter          100.00%


                                      A-5
<PAGE>
 
     In addition, at any time prior to August 15, 1999, the Company may redeem
up to one-third of the Notes originally issued, at any time as a whole or from
time to time in part, with the proceeds of one or more Public Equity Offerings
or sales of Capital Stock (other than Redeemable Stock) to one or more Strategic
Equity Investors, each such Public Equity Offering or sale to Strategic Equity
Investors resulting in Net Cash Proceeds of $50 million or more, at a redemption
price (expressed as a percentage of principal amount) of 111.625%, plus accrued
and unpaid interest and Liquidated Damages, if any, to the Redemption Date,
provided that after any such redemption at least two-thirds of the aggregate
principal amount of Notes originally outstanding remains outstanding and each
such redemption is effected not more than 60 days after the consummation of such
Public Equity Offering or sale to Strategic Equity Investors.

     If less than all of the Notes are to be redeemed at any time, the Trustee
will select the Notes, or portions thereof, for redemption in compliance with
the requirements of the principal national securities exchange, if any, on which
the Notes are listed or, if the Notes are not listed on a national securities
exchange, on a pro rata basis, by lot or by such other method as the Trustee in
its sole discretion shall deem to be fair and appropriate.  Notes in
denominations larger than $1,000 may be redeemed in part.  Any notice mailed as
provided herein and in the Indenture will be conclusively presumed to have been
given whether or not actually received by any Holder.  On and after the
Redemption Date, interest ceases to accrue on Notes or portions of Notes called
for redemption, unless the Company defaults in the payment of the Redemption
Price.  A new Note in original amount equal to the unredeemed portion thereof
will be issued in the name of the Holder thereof upon cancellation of the
original Note.

     (6)  Repurchase upon Change of Control and Asset Sale.  The Company shall
          ------------------------------------------------                    
commence within 30 days of the occurrence of a Change of Control and consummate
an Offer to Purchase for all Notes then outstanding at a purchase price equal to
101% of the principal amount thereof, plus accrued and unpaid interest and
Liquidated Damages, if any, to the Payment Date.  The Notes may also be subject
to an Offer to Purchase in connection with an Asset Sale.  Any Note delivered
for payment of a purchase price shall be accompanied by an instrument in the
form of the Option of the Holder to Elect Purchase below.

     (7)  Denominations; Transfer; Exchange.  The Notes are in registered form
          ---------------------------------                                   
without coupons in denominations of $1,000 of principal amount and  multiples of
$1,000 in excess thereof.  A Holder may register the transfer or exchange of
Notes in accordance with the Indenture.  The Registrar may require a Holder,
among other things, to furnish appropriate endorsements and transfer documents
(including a certificate in the form of the Certificate to be Delivered upon
Exchange or Registration of Transfer of Securities below) and to pay any taxes,
fees and/or other governmental charges required by law or permitted by the
Indenture.  The Registrar need not register the transfer or exchange of any
Notes selected for redemption.  Also, it need not register the transfer or
exchange of any Notes for a period of 15 days before the day of the mailing of a
notice of redemption of Notes selected for redemption.

     (8)  Persons Deemed Owners.  A Holder shall be treated as the owner of a
          ---------------------                                              
Note for all purposes.

     (9)  Unclaimed Money.  If money for the payment of principal, premium and
          ---------------                                                     
Liquidated Damages, if any, or interest remains unclaimed for two years, the
Trustee and the Paying Agent will pay the money back to the Company at its
written request.  After that, Holders entitled to the money must look to the
Company for payment, unless applicable law designates another Person, and all
liability of the Trustee and such Paying Agent with respect to such money shall
cease.


                                      A-6
<PAGE>
 
     (10)  Defeasance and Discharge Prior to Redemption or Maturity.  If the
           --------------------------------------------------------         
Company deposits with the Trustee money or U.S. Government Obligations
sufficient to pay the then outstanding principal of, premium and Liquidated
Damages, if any, and accrued interest on the Notes to redemption or maturity,
and complies with certain other provisions of the Indenture relating thereto,
(i) the Company will be deemed to have paid and will be discharged from any and
all obligations in respect of the Notes or (ii) certain provisions set forth in
the Indenture will no longer be in effect with respect to the Notes.

     (11)  Amendment; Supplement; Waiver.  Subject to certain exceptions, the
           -----------------------------                                     
Indenture or the Notes may be amended or supplemented with the consent of the
Holders of at least a majority in aggregate principal amount of the Notes then
outstanding, and any existing default or compliance with any provision may be
waived with the consent of the Holders of at least a majority in principal
amount of the Notes then outstanding.  Without notice to or the consent of any
Holder, the parties thereto may amend or supplement the Indenture or the Notes
to, among other things, cure any ambiguity, defect or inconsistency and make any
change that does not adversely affect the rights of any Holder.

     (12)  Restrictive Covenants. The Indenture imposes certain limitations on
           ---------------------                                              
the ability of the Company and its Restricted Subsidiaries, among other things,
to (a) Incur additional Indebtedness, (b) make Restricted Payments, (c) use the
proceeds from Asset Sales, (d) suffer to exist restrictions on the ability of
Restricted Subsidiaries to make certain payments to the Company, (e) issue
Capital Stock of Restricted Subsidiaries, (f) engage in transactions with
certain stockholders and Affiliates, (g) suffer to exist or incur Liens, (h)
Guarantee Indebtedness of the Company or (i) merge, consolidate or transfer
substantially all of its assets.  Within 90 days after the end of the last
fiscal quarter of each year, the Company shall deliver to the Trustee an
Officers' Certificate stating whether or not the signers know of any Default or
Event of Default under such restrictive covenants.

     (13)  Successor Persons.  When a successor person or other entity assumes
           -----------------                                                  
all the obligations of its predecessor under the Notes and the Indenture, the
predecessor person will be released from those obligations.

     (14)  Defaults and Remedies.  An Event of Default is: (a) a default in
           ---------------------                                           
payment of principal or premium, if any, on the Notes; (b) default in the
payment of interest or Liquidated Damages, if any, on the Notes for 30 days; (c)
failure by the Company for 30 days after notice to it to comply with any of its
other agreements in the Indenture; (d) certain events of bankruptcy or
insolvency as described in the Indenture; (e) certain final judgments which
remain undischarged as described in the Indenture; and (f) certain events of
default on other Indebtedness of the Company and/or one or more of its
Significant Subsidiaries as described in the Indenture.

     If an Event of Default, as defined in the Indenture, occurs and is
continuing, the Trustee or the Holders of at least 25% in aggregate principal
amount of the Notes then outstanding may, and the Trustee at the request of such
Holders shall, declare all the Notes to be due and payable.  If a bankruptcy or
insolvency default with respect to the Company occurs and is continuing, the
Notes automatically become due and payable.  Holders may not enforce the
Indenture or the Notes, or take any action with respect to any Event of Default
under the Indenture, or to institute, appear in or defend any suit or other
proceeding with respect thereto, except as provided in the Indenture.  The
Trustee may require indemnity satisfactory to it before it enforces the
Indenture or the Notes.  Subject to certain limitations under the Indenture,
Holders of at least a majority in principal amount of the Notes then outstanding
may direct in accordance with the provisions of the Indenture the Trustee in its
exercise of any trust or power, including waiver of all past 


                                      A-7
<PAGE>
 
defaults, rescission and annulment of a declaration of acceleration and its
consequences and exercise of any right, remedy or power available to the
Trustee.

     (15)  Trustee Dealings with Company.  The Trustee under the Indenture, in
           -----------------------------                                      
its individual or any other capacity, may make loans to, accept deposits from
and perform services for the Company or its Affiliates and may otherwise deal
with the Company or its Affiliates as if it were not the Trustee.

     (16)  No Recourse Against Others.  No incorporator or any past, present or
           --------------------------                                          
future partner, shareholder, other equity holder, officer, director, employee or
controlling person as such, of the Company or of any successor Person shall have
any liability for any obligations of the Company under the Notes or the
Indenture or for any claim based on, in respect of or by reason of, such
obligations or their creation.  Each Holder by accepting a Note expressly waives
and releases all such liability.  The waiver and release are a condition of, and
part of the consideration for the issuance of the Notes.

     (17)  Authentication.  This Note shall not be entitled to any right or
           --------------                                                  
benefit under the Indenture, or be valid, or become obligatory for any purpose,
until the Trustee or authenticating agent signs the certificate of
authentication on the other side of this Note.

     (18)  Abbreviations.  Customary abbreviations may be used in the name of a
           -------------

TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of
survivorship and not as tenants in common), CUST (= Custodian) and 
U/G/M/A (= Uniform Gifts to Minors Act).

     The Company will furnish to any Holder upon written request and without
charge a copy of the Indenture.  Requests may be made to Omnipoint Corporation,
2000 North 14th Street, Suite 550, Arlington, VA 22201, Attention:  Bradley E.

           applicable jurisdiction;

                (iii)  will offer and sell the Notes only (y) to persons who it
           reasonably believes to be QIBs or (z) to institutions which it
           reasonably believes are Institutional Accredited Investors that

           offering memorandum is available upon request and will, during its
           initial distribution of the Notes, furnish to each person to whom it
           sells any Notes a copy of the Offering Memorandum (as then amended or
           supplemented).

3.   Agreements to Sell and Purchase.  On the basis of the representations and
     -------------------------------                                          
warranties contained in this Agreement, and subject to the terms and conditions
contained in this Agreement, the Company agrees to issue and sell to the Initial
Purchasers, and each Initial Purchaser agrees, severally and not jointly, to
purchase from the Company, Notes in the respective principal amount set forth
opposite the name of such Initial Purchaser in Schedule I hereto, plus such
amount as they may individually become obligated to purchase pursuant to Section
8 hereof, at a purchase price per Security equal to the percentage of the
principal amount thereof set forth in the table on the cover page of the
Offering Memorandum under the heading "Proceeds to the Company" (the "Purchase
Price").  The portion of the Purchase Price so set forth in the Offering
Memorandum will be paid into the Escrow Account.

     The Notes will be offered and sold to you without being registered under
the Act in reliance on an exemption therefrom.  The Company has prepared a
preliminary offering memorandum dated November 20, 1996 (such preliminary
offering memorandum is referred to herein as the "preliminary offering
memorandum"), and an offering memorandum dated November  21, 1996 (such offering
memorandum, in the form first furnished to the Initial Purchasers for use in
connection with the offering of the Notes, is referred to herein as the
"Offering Memorandum"), setting forth information regarding the Company and the
Notes.  

                                       4
<PAGE>
 
The Company hereby confirms that it has authorized the use of the preliminary
offering memorandum and the Offering Memorandum in connection with the offering
and resale of the Notes.

     Holders (including subsequent transferees) of the Notes will have the
registration rights set forth in the Registration Rights Agreement (the
"Registration Rights Agreement"), to be dated the Closing Date, in substantially
the form of Exhibit B hereto, for so long as such Notes constitute "Registrable
Securities" (as defined in the Registration Rights Agreement).  Pursuant to the
Registration Rights Agreement, the Company will agree to file with the
Commission under the circumstances set forth therein (i) a registration
statement under the Act (the "Exchange Offer Registration Statement"),
registering an issue of senior notes identical in all material respects to the
Notes (the "Exchange Notes"), to be offered in exchange for the Notes (the
"Exchange Offer"), or (ii), under certain circumstances, a registration
statement pursuant to Rule 415 under the Act (the "Shelf Registration Statement"
and collectively, with the Exchange Offer Registration Statement, the
"Registration Statements").

4.   Agreements of the Company.  The Company agrees with each of you that:
     -------------------------                                            

     (a)   It will advise you promptly and, if requested by you, confirm such
advice in writing, of the happening of any event during the period as in your
judgment you are required to deliver an Offering Memorandum in connection with
sales of the Notes by you which makes any statement of a material fact made in
the Offering Memorandum untrue or which requires the making of any additions to
or changes in the Offering Memorandum (as amended or supplemented from time to
time) in order to make the statements therein, in light of the circumstances
under which they were made, not misleading.

     (b)   It will notify you promptly of (i) the receipt of any comments from
any state securities commission or any other regulatory authority that relate to
the preliminary offering memorandum or the Offering Memorandum, (ii) the
suspension of qualification of the Notes for offering or sale in any
jurisdiction, or the initiation of any proceeding for such purpose by any state
securities commission or any other regulatory authority. The Company shall use
its best efforts to prevent the issuance of any stop order or order suspending
the qualification or exemption of the Notes under any state securities or Blue
Sky laws, and, if at any time any 

                                       5
<PAGE>
 
state securities commission or any other regulatory authority shall issue an
order suspending the qualification or exemption of the Notes under any state
securities or Blue Sky laws, the Company shall use its best efforts to obtain
the withdrawal or lifting of such order at the earliest possible time.

     (c)   Promptly after the execution of this Agreement, and from time to time
thereafter for such period as in your judgment the Offering Memorandum is
required to be delivered in connection with sales of the Notes by you, it will
furnish to you, without charge, as many copies of the Offering Memorandum (and
of any amendment or supplement to the Offering Memorandum) as you may reasonably
request.

     (d)   If, during such period as in your judgment you are required to
deliver the Offering Memorandum in connection with sales of the Notes by you,

or (ii) the date the Shelf Registration Statement is declared effective by the

Company shall be obligated to deliver, upon request, any information required by

     (n)   It will not, and will ensure that no affiliate (as such term is
defined in the Commission's Rule 501(b) under the Act) of the Company will
offer, sell or solicit offers to buy or otherwise negotiate in respect of any
"security" (as defined in the Act) which could be integrated with the offer and
sale of the Notes in a manner that would require the registration of the Notes
under the Act.

     (o)   Except in connection with the Exchange Offer or the filing of the
Shelf Registration Statement, as the case may be, it will not, and will not
authorize or knowingly permit any person acting on its behalf to, solicit any
offer to buy or offer to sell the Notes by means of any form of general

     ------------------------------                                         
each of you that:

     (a)   Each of the preliminary offering memorandum and the Offering
Memorandum, as of its date, contains all the information that, if requested by a
prospective purchaser of the Notes, would be required to be provided pursuant to
Rule 144A(d)(4) under the Act. The Offering Memorandum does not, and at the
Closing Date will not, contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary to make
the statements therein, in light of the circumstances under which they were
made, not misleading, except that the representations and warranties contained
in this paragraph (a) shall not apply to statements in or omissions from the
preliminary offering memorandum or the Offering Memorandum (or any supplement or
amendment to them),  made in reliance upon and in conformity with information
relating to the

<PAGE>
 
Initial Purchasers furnished to the Company in writing by or on behalf of the
Initial Purchasers by you expressly for use therein. The Company acknowledges
for all purposes under this Agreement (including this paragraph and Section 6
hereof and legal opinions) that the statements set forth in the third paragraph
(first four sentences) and fourth paragraph (third sentence), under the caption
"Plan of Distribution" and in the last paragraph of the cover page in any
preliminary offering memorandum and in the Offering Memorandum constitute the
only written information furnished to the Company by or on behalf of the Initial
Purchasers expressly for use in the Offering Memorandum (or any amendment or
supplement to any of them), and that the Initial Purchasers shall not be deemed
to have provided any information (and therefore are not responsible for any
statements or omissions), pertaining to any arrangement or agreement with
respect to any party other than the Initial Purchasers. On the date hereof, at
the date of the Offering Memorandum, and any amendment or supplement thereto (if
different), and at the Closing Date, the Indenture will conform in all material
respects to the requirements of the Trust Indenture Act of 1939, as amended, and
the rules and regulations promulgated pursuant thereto (collectively, the
"TIA"), which would be applicable to an Indenture qualified under the TIA. No
contract or document of a character required to be described in the Offering
Memorandum, were the Offering Memorandum to be the form of prospectus contained
in a registration statement under the Act on Form S-1, has not been described as
so required.

     (b) No action has been taken and no statute, rule, regulation or order has
been enacted, adopted or issued by any governmental body, agency or official
which prevents the issuance of the Notes or prevents or suspends the use of any
preliminary offering memorandum or suspends the sale of the Notes in any
jurisdiction referred to in Section 4(h) hereof; no injunction, restraining
order or order of any nature by any Federal or state court of competent
jurisdiction has been issued with respect to the Company which would prevent or
suspend the issuance or sale of the Notes or the use of any preliminary offering
memorandum or the Offering Memorandum in any jurisdiction referred to in Section
4(h) hereof; no action, suit or proceeding before any court or arbitrator or any
governmental body, agency or official, domestic or foreign, is pending against
or, to the best knowledge of the Company, threatened against the Company which,
if adversely determined, could materially interfere with or adversely affect the
issuance of the Notes or in any manner draw into question the validity of the
Registration Rights Agreement, this Agreement, the Indenture or the Notes.

     (c) The Indenture has been duly authorized by the Company and, when duly
executed and delivered by the Company in accordance with its terms, will be a
legal, valid and binding agreement of the Company, enforceable against the
Company in accordance with its terms, except as such enforceability may be
limited by applicable bankruptcy, insolvency, reorganization, moratorium,
fraudulent transfer and similar laws affecting creditors' rights and remedies
generally and to general principles of equity (regardless of whether enforcement
is sought in a proceeding at law or in equity) and except to the extent that a
waiver of rights or defenses under any usury laws may be unenforceable.

     (d) The Notes have been duly authorized by the Company and, on the Closing
Date, will have been duly executed by the Company and will, when issued,
executed, authenticated and delivered in accordance with the Indenture and paid
for in accordance with the terms of this Agreement, constitute legal, valid and
binding obligations of the Company, enforceable against the Company in
accordance with their terms, except as such enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent
transfer and similar laws  affecting creditors' rights and remedies generally
and to general principles of equity (regardless of whether enforcement is sought
in a proceeding at law or in equity), and except to the extent that a waiver of
rights or defenses under any usury laws may be unenforceable.  The Notes will be
entitled to the benefits of the Indenture and will conform in all material
respects to the descriptions thereof in the Offering Memorandum.

     (e) This Agreement has been duly authorized and validly executed and
delivered by the Company and constitutes a valid and legally binding agreement
of the Company, enforceable against the Company in accordance with its terms
(assuming due execution and delivery by you of this Agreement), except as rights
of indemnity or contribution, or both, may be limited by state and Federal laws.

     (f) The execution and delivery of this Agreement, the Indenture, the
Registration Rights Agreement, the Escrow Agreement and the Notes by the
Company, the issuance and sale of the Notes, the performance of this Agreement
and the Indenture and the consummation of the transactions contemplated by this
Agreement and the Indenture will not conflict with or result in a breach or
violation of (A) any of the respective charters or bylaws of the Company or any
of 

                                       12
<PAGE>
 
the Subsidiaries or (B) any of the terms or provisions of, or constitute a
default or cause an acceleration of any obligation under or result in the
imposition or creation of (or the obligation to create or impose) any security
interest, mortgage, pledge, claim, lien, encumbrance or adverse interest of any
nature (each, a "Lien"), with respect to, any obligation, bond, agreement, note,
debenture, or other evidence of indebtedness, or any indenture, mortgage, deed
of trust or other agreement, lease or instrument to which the Company or any
Subsidiary is a party or by which it or any of them is bound, or to which any
properties of the Company or any Subsidiary is or may be subject, or contravene
any order of any court or governmental agency, body or official having
jurisdiction over the Company or any Subsidiary or any of their properties, or
violate or conflict with any statute, rule or regulation or administrative
regulation or decree or court decree applicable to the Company or any Subsidiary
or any of their respective assets or properties.

     (g) Each of the Registration Rights Agreement and the Escrow Agreement has
been duly and validly authorized by the Company and on the Closing Date will
have been duly executed and delivered by the Company and, when duly executed and
delivered by the other parties thereto, will be a legal, valid and binding
agreement of the Company, enforceable against the Company in accordance with its
terms, except as rights of indemnity or contribution, or both, may be limited by
state and Federal laws and except as such enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent
transfer and similar laws affecting creditors' rights and remedies generally and
to general principles of equity (regardless of whether enforcement is sought in
a proceeding at law or in equity).  Each of the Registration Rights Agreement
and the Escrow Agreement conforms in all material respects with the descriptions
thereof in the Offering Memorandum.

     (h) No authorization, approval or consent or order of, or filing with, any
court or governmental body, agency or official is necessary in connection with
the transactions contemplated by this Agreement, the Registration Rights
Agreement, the Escrow Agreement and the Indenture except such as may be required
by state securities or Blue Sky laws or regulations and, with respect to the
Registration Rights Agreement, the Act and the TIA.  None of the Company nor any
of its affiliates is presently doing business with the government of Cuba or
with any person or affiliate located in Cuba.

     (i) The Company and each of the Subsidiaries has been duly incorporated, is
validly existing as a corporation in good standing under the laws of its
jurisdiction of incorporation and has the requisite power and authority to carry
on its business as it is currently being conducted and as described in the
Offering Memorandum as proposed to be conducted, and to own, lease and operate
its properties, as applicable, and, with respect to the Company, to authorize
the offering of the Notes, to execute, deliver and perform this Agreement, the
Indenture, the Escrow Agreement and the Registration Rights Agreement and to
issue, sell and deliver the Notes; and the Company and each of the Subsidiaries
is duly qualified and is in good standing as a foreign corporation authorized to
do business in each jurisdiction in which the nature of its business or its
ownership or leasing of property requires such qualification, except where the
failure to be so qualified would not have a material adverse effect, whether
singly or in the aggregate, on the properties, business, results of operations,
affairs, condition (financial or otherwise) or prospects of the Company and the
Subsidiaries taken as a whole (a "Material Adverse Effect");

     (j) The consolidated capitalization of the Company is as set forth in the
Offering Memorandum, under the caption "Capitalization" in the column "Actual"
and, after consummation of the Offering, will be as set forth in the column "As
Adjusted."

     (k) All of the outstanding shares of capital stock of, or other ownership
interests in, each Subsidiary have been duly authorized and validly issued and
are fully paid and nonassessable, and other than (i) the ownership by an
unaffiliated third-party of 549 shares of common stock, $0.01 par value (the
"OCI Common Stock"), of Omnipoint Communications Inc., a Delaware corporation
("OCI"), constituting 4.4% of the outstanding capital stock of OCI and (ii) the
pledge by Omnipoint PCS, Inc., a Delaware corporation, of 11,874 shares of OCI
Common Stock, constituting 95.6% of the outstanding capital stock of OCI, to
Mellon Bank, N.A., as collateral agent for the ratable benefit of Northern
Telecom Inc., as administrative agent and Ericsson Inc., as administrative
agent, pursuant to the Amended and Restated Pledge Agreement dated as of August
7, 1996, are owned by the Company free and clear of any Lien.  There are no
outstanding subscriptions, rights, warrants, options, calls, convertible or
exchangeable securities, commitments of sale, or Liens related to or entitling
any person to purchase or other-

                                       14
<PAGE>
 
wise to acquire any shares of the capital stock of, or other ownership interest
in, any Subsidiary.

     (l) Neither the Company nor any Subsidiary is (A) in violation of its
respective charter or bylaws or (B) in default in the performance of any
obligation, bond, agreement, debenture, note or any other evidence of
indebtedness, or any indenture, mortgage, deed of trust or other contract, lease
or other instrument to which it is a party or by which it is bound, or to which
any of the property or assets any of them is subject, except in the case of (B)
defaults which, singly or in the aggregate, as could not reasonably be expected
to have a Material Adverse Effect.

     (m) There is no action, suit or proceeding before or by any court or
governmental agency or body, domestic or foreign, pending against or affecting
the Company or any Subsidiary or any of their respective assets or properties,
which, taken singly or in the aggregate, could have a Material Adverse Effect,
or which might materially and adversely affect the performance by the Company of
its obligations pursuant to this Agreement or the transactions contemplated
hereby or thereby and, to the best knowledge of the Company, no such action,
suit or proceeding is contemplated or threatened.

     (n) Neither the Company nor any Subsidiary has violated any foreign,
federal, state or local law or regulation relating to the protection of human
health and safety or the environment or hazardous or toxic substances or wastes,
pollutants or contaminants ("Environmental Laws"), nor any federal or state law
relating to discrimination in the hiring, promotion or pay of employees nor any
applicable federal or state wages and hours laws, nor any provisions of the
Employee Retirement Income Security Act, as amended, or the rules and
regulations promulgated thereunder, which violations, singly or in the
aggregate, could reasonably be expected to have a Material Adverse Effect.

     (o) The Company and each of the Subsidiaries has such permits, licenses,
franchises and authorizations of governmental or regulatory authorities
("permits"), including, without limitation, under any applicable Environmental
Laws, as are necessary to own, lease and operate its respective properties and
to carry on its business as it is currently being conducted and as it is
proposed to be conducted as described in the Prospectus; the Company and each of
the 

                                       15
<PAGE>
 
Subsidiaries has fulfilled and performed all of its material obligations with
respect to such permits and no event has occurred which allows, or after notice
or lapse of time would allow, revocation or termination thereof or results in
any other material impairment of the rights of the holder of any such permit;
and, except as described in the Offering Memorandum, such permits contain no
restrictions that are materially burdensome to the Company or any of the
Subsidiaries.

     (p) In the ordinary course of its business, the Company conducts a periodic
review of the effect of Environmental Laws on the business, operations and
properties of the Company and the Subsidiaries, in the course of which it
identifies and evaluates associated costs and liabilities (including, without
limitation, any capital or operating expenditures required for clean-up, closure
of properties or compliance with Environmental Laws or any permit, license or
approval, any related constraints on operating activities and any potential
liabilities to third parties).  On the basis of such review, the Company has
reasonably concluded that such associated costs and liabilities, singly or in
the aggregate, could not reasonably be expected to have a Material Adverse
Effect.

     (q) Except as could not reasonably be expected to have a Material Adverse
Effect, each of the Company and the Subsidiaries has good and marketable title,
free and clear of all Liens (except as permitted by clauses (v), (vi) and (viii)
of Section 4.9 of the Indenture), to all property and assets described in the
Offering Memorandum as being owned by it and such properties and assets are in
the condition and suitable for use as so described.  All leases to which any of
the Company and the Subsidiaries is a party are valid and binding and no default
has occurred and is continuing thereunder (in the case of defaults by persons
other than the Company and the Subsidiaries, to the best knowledge of the
Company and the Subsidiaries), which could, singly or in the aggregate,
reasonably be expected to have a Material Adverse Effect, and the Company and
the Subsidiaries enjoy peaceful and undisturbed possession under all such leases
to which any of them is a party as lessee with such exceptions as do not
interfere with the use made or proposed to be made by them.

     (r) The Company and the Subsidiaries maintain insurance at least in such
amounts and covering at least such risks as is adequate for the conduct of their
respective businesses and the value of their respective properties and as is
customary for companies engaged in similar businesses in similar industries.

     (s) Coopers & Lybrand L.L.P., the firm of accountants that has certified or
shall certify the applicable consolidated financial statements of the Company
and subsidiaries and the other financial statements included or to be included
as part of the Offering Memorandum, are independent public accountants with
respect to the Company,  as would be required under the Act.  The consolidated
financial statements and the other financial statements, together with related
schedules and notes, set forth in the Offering Memorandum, comply as to form in
all material respects with the requirements applicable to registration
statements on Form S-1 under the Act and fairly present the consolidated
financial position of the Company and the financial position of its subsidiaries
at the respective dates indicated and the results of their operations and their
cash flows, as applicable, for the respective periods indicated, and were
prepared in accordance with generally accepted accounting principles in the
United States of America ("GAAP"), consistently applied throughout such periods
subject in the case of interim statements to normal recurring adjustments.  The
other financial and statistical information and data included in the Offering
Memorandum are accurately presented and prepared on a basis consistent with the
financial statements and the books and records of the Company.

     (t) Subsequent to the respective dates as of which information is given in
the Offering Memorandum and up to the Closing Date, except as set forth in the
Offering Memorandum, neither the Company nor any of the Subsidiaries has
incurred any liabilities or obligations, direct or contingent, which are
material to the Company and the Subsidiaries, taken as a whole, nor entered into
any transaction not in the ordinary course of business and there has not been,
singly or in the aggregate, any material adverse change, or any development
which could reasonably be expected to involve a material adverse change, in the
properties, business, results of operations, condition (financial or otherwise),
affairs or prospects of the Company and the Subsidiaries, taken as a whole (a
"Material Adverse Change").

     (u) The Company and each of the Subsidiaries have filed (or have had filed
on their behalf) all tax returns required to be filed by any of them prior to
the date hereof under applicable law, other than those filings being contested
in good faith.  All such tax returns and amendments thereto are true, correct
and complete in all material respects.  The Company and each of the Subsidiaries
have paid (or 

                                       17
<PAGE>
 
have had paid on their behalf) all material taxes, including all Federal, state,
local and foreign taxes, and other assessments of a similar nature (whether
imposed directly or through withholding), including any interest, additions to
tax, or penalties applicable thereto, other than those taxes being contested in
good faith and for which adequate reserves have been provided or those currently
payable without penalty or interest. To the best of the Company's and each of
the Subsidiaries' knowledge, there are no tax items of a material nature that
are currently under examination by the Internal Revenue Service or any other
domestic or foreign governmental authority responsible for the administration of
any such taxes.

     (v) The Company and the Subsidiaries possess the patents, patent rights,
licenses, inventions, copyrights, know-how (including trade secrets and other
unpatented and/or unpatentable proprietary or confidential information, systems
or procedures), trademarks, service marks and trade names (collectively,
"Intellectual Property"), presently employed by them in connection with the
businesses now operated by them, and neither the Company nor any Subsidiary has
received any notice of infringement of or conflict with asserted rights of
others with respect to the foregoing except as could not, singly or in the
aggregate, reasonably be expected to have a Material Adverse Effect.  The use of
such Intellectual Property in connection with the business and operations of the
Company and the Subsidiaries does not infringe on the rights of any person.

     (w) (i)  Except as set forth in the Offering Memorandum, (i) the Company
and each of the Subsidiaries have applied for or obtained all certificates,
consents, exemptions, orders permits, licenses, authorizations or other
approvals (each, an "Authorization") of and from, and has made all declarations
and filings with, all Governmental Authorities, including, without limitation,
the Federal Communications Commission ("FCC") and each applicable state
regulatory agency or body that exercises or will exercise jurisdiction over the
Company ("Applicable PUC"), necessary to conduct its business as it is currently
being conducted and as it is proposed to be conducted as described in the
Offering Memorandum, except to the extent that the failure to obtain, declare or
file would not, singly or in the aggregate, have a Material Adverse Effect, (ii)
all such Authorizations are valid and in full force and effect, except where the
failure of any such Authorization to be in full force and effect would not,
singly or in the aggregate, have a Material Adverse Effect and (iii) the Company
and each of the Subsidiaries is in compliance 

                                       18

     (y) Neither the Company nor any Subsidiary nor any agent acting on their
behalf has taken or will take any action that is reasonably likely to cause the

     (ab) Except as disclosed in the Offering Memorandum, there are no business

     (ac) On the Closing Date, the Notes will have been approved for inclusion

     (ad) Neither the Company nor any affiliate (as such term is defined in Rule
501(b) under the Act) of the Company has, directly or through any agent, sold,
offered for sale, solicited offers to buy or otherwise negotiated in respect of,
any "security" (as defined in the Act) which is or will be integrated with the
sale of the Notes in a manner that would require registration of the offering
and sale of the Notes under the Act.

     (ae) Neither the Company nor any officer, director or other person (other
than you, as to whom the Company makes no representation), acting on its behalf
has engaged, in connection with the offering of the Notes, in any form of
general solicitation or general advertising, including but not limited to the
methods described in Rule 502(c) under the Act.

                                       20

     (af) Assuming the accuracy of your representations contained in Section
2(b) hereof and your compliance with your agreements therein set forth, it is
not necessary, in connection with the sale and delivery of the Notes to you and

the date hereof no event or condition which would constitute a default or an
event of default (in each case as defined in the Senior Notes, the NT Credit
Facility or the Ericsson Credit Facility, as applicable), under either such
facility which would result in a Material Adverse Effect or materially adversely
effect the ability of the Company to consummate the transactions contemplated by
this Agreement.  The Senior Notes, the NT Credit Facility and the Ericsson
Credit Facility conform in all material respects with the respective
descriptions thereof in the Offering Memorandum.

     (ah) Each certificate signed by any officer of the Company and delivered to

matters covered thereby.

6.   Indemnification.
     --------------- 

     (a) The Company agrees to indemnify and hold harmless (i) each of the
Initial Purchasers and (ii) each person, if any, who controls (within the
meaning of Section 15 of the Act or Section 20 of the Exchange Act), any of the
Initial Purchasers (any of the persons referred to in this clause (ii) being
hereinafter referred to as a "controlling person"), and (iii) the respective
officers, directors, partners, employees, representatives and agents of any of
the Initial Purchasers or any controlling person (any person referred to in
clause (i), (ii) or (iii) may 

                                       21
<PAGE>
 
hereinafter be referred to as an "Indemnified Person"), to the fullest extent
lawful, from and against any and all losses, claims, damages, judgments,
actions, expenses and other liabilities (collectively, "Liabilities"), including
without limitation and as incurred, reimbursement of all reasonable costs of
investigating, preparing, pursuing or defending any claim or action, or any
investigation or proceeding by any governmental agency or body, commenced or
threatened, including the reasonable fees and expenses of counsel to any
Indemnified Person, directly or indirectly caused by, related to, based upon,
arising out of or in connection with any untrue statement or alleged untrue
statement of a material fact contained in the Offering Memorandum (including any
amendment or supplement thereto), or any preliminary offering memorandum, or any
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein (in light of the
circumstances under which they were made), not misleading, except insofar as
such Liabilities are caused by an untrue statement or omission or alleged untrue
statement or omission that is (x) made in reliance upon and in conformity with
information relating to either of the Initial Purchasers furnished in writing to
the Company by or on behalf of such Initial Purchaser expressly for use in any
preliminary offering memorandum or the Offering Memorandum (or any amendment or
supplement thereto), or (y) with respect to the Initial Purchaser from whom the
person asserting the Liabilities purchased Notes, made in any preliminary
offering memorandum if a copy of the Offering Memorandum (as amended or
supplemented, if the Company shall have furnished the Initial Purchasers with
such amendments or supplements thereto on a timely basis), was not delivered by
or on behalf of such Initial Purchaser to the person asserting the Liabilities,
if required by law to have been so delivered by the Initial Purchaser seeking
indemnification, at or prior to the written confirmation of the sale of the
Notes, and it shall be finally determined by a court of competent jurisdiction,
in a judgment not subject to appeal or review, that the Offering Memorandum (as
so amended or supplemented), would have completely corrected such untrue
statement or omission. The Company shall notify you promptly of the institution,
threat or assertion of any claim, proceeding (including any governmental
investigation), or litigation in connection with the matters addressed by this
Agreement which involves the Company or an Indemnified Person.

     (b) In case any action or proceeding (for all purposes of this Section 6,
including any governmental investigation), shall be brought or asserted against
any of the Indemnified Persons with respect to which indemnity may be sought
against 

                                       22
<PAGE>
 
the Company, such Indemnified Person shall promptly notify the Company
in writing; provided, that the failure to give such notice shall not relieve the
            --------                                                            
Company of its obligations pursuant to this Agreement. Upon receiving such
notice, the Company shall assume, at its sole expense, the defense thereof, with
counsel reasonably satisfactory to such Indemnified Person and, after written
notice from the Company to such Indemnified Person of its election so to assume
the defense thereof made within five business days after receipt of the notice
from the Indemnified Person of such action or proceeding, the Company shall not
be liable to such Indemnified Person hereunder for legal expenses of other
counsel subsequently incurred by such Indemnified Person in connection with the
defense thereof, other than costs of investigation, unless (i) the Company
agrees in writing to pay such fees and expenses, or (ii) the Company fails
promptly to assume such defense or fails to employ counsel reasonably
satisfactory to such Indemnified Person or (iii) the named parties to any such
action or proceeding (including any impleaded parties), include both such
Indemnified Person and any of the Company or an affiliate of the Company, and
either (x) such Indemnified Person shall have been advised by counsel that there
may be one or more legal defenses available to such Indemnified Person that are
different from or additional to those available to one or more of the Company or
such affiliate or (y) a conflict may exist between such Indemnified Person and
the Company or such affiliate. In the event of any of clause (i), (ii) and (iii)
of the immediately preceding sentence, if such Indemnified Person notifies the
Company in writing, the Company shall not have the right to assume the defense
thereof and such Indemnified Person shall have the right to employ its own
counsel in any such action and the reasonable fees and expenses of such counsel
shall be paid, as incurred, by the Company, it being understood, however, that
the Company shall not, in connection with any one such action or proceeding or
separate but substantially similar or related actions or proceedings arising out
of the same general allegations or circumstances, be liable for the fees and
expenses of more than one separate firm of attorneys (in addition to any local
counsel) at any time for all such Indemnified Persons. The Company agrees to be
liable for any settlement of such action or proceeding effected with the
Company's prior written consent, which consent will not be unreasonably
withheld, and the Company agrees to indemnify and hold harmless any Indemnified
Person from and against any Liabilities by reason of any settlement of any
action effected with the written consent of the Company. The Company agrees to
be liable for any settlement of any proceeding effected without its written
consent if (i) such settlement is entered into more than ten business days after
receipt by the Company

                                       23
<PAGE>
 
of the aforesaid request for payment in respect of an indemnification obligation
pursuant hereto and (ii) the Indemnified Person shall not have been reimbursed
in accordance with such request prior to the date of such settlement. The
Company shall not, without the prior written consent of each Indemnified Person,
settle or compromise or consent to the entry of any judgment in or otherwise
seek to terminate any pending or threatened action, claim, litigation or
proceeding in respect of which indemnification or contribution may be sought
pursuant hereto (whether or not any Indemnified Person is a party thereto),
unless such settlement, compromise, consent or termination includes an
unconditional release of each Indemnified Person from all liability arising out
of such action, claim, litigation or proceeding.

     (c) Each of the Initial Purchasers agrees, severally and not jointly, to
indemnify and hold harmless the Company and any person controlling (within the
meaning of Section 15 of the Act or Section 20 of the Exchange Act) the Company,
and the officers, directors, partners, employees, representatives and agents of
each such person, to the same extent as the foregoing indemnity from the Company
to each of the Indemnified Persons, but only with respect to claims and actions
based on information relating to such Initial Purchaser and conforming to
information furnished in writing by or on behalf of such Initial Purchaser
expressly for use in the Offering Memorandum or any preliminary offering
memorandum, as applicable.  In case any action or proceeding (including any
governmental investigation), shall be brought or asserted against the Company,
any of its directors, any such officer, or any such controlling person based on
the Offering Memorandum or any preliminary offering memorandum in respect of
which indemnity is sought against any Initial Purchaser pursuant to the
foregoing sentence, the Initial Purchaser shall have the rights and duties given
to the Company (except that if the Company shall have assumed the defense
thereof, such Initial Purchaser shall not be required to do so, but may employ
separate counsel therein and participate in the defense thereof but the fees and
expenses of such counsel shall be at the expense of such Initial Purchaser), and
the Company, its directors, any such officers and each such controlling person
shall have the rights and duties given to the Indemnified Person by Section 7(b)
above.

     (d) If the indemnification provided for in this Section 6 is finally
determined by a court of competent jurisdiction to be unavailable to an
indemnified party in respect of any Liabilities referred to herein, then each
indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid 

                                       24
<PAGE>
 
or payable by such indemnified party as a result of such Liabilities (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company, on the one hand, and such Initial Purchaser, on the other hand, from
the offering of the Notes or (ii) if the allocation provided by clause (i) above
is not permitted by applicable law, in such proportion as is appropriate to
reflect not only the relative benefits referred to in clause (i) above, but also
the relative fault of the indemnifying parties and the indemnified party, as
well as any other relevant equitable considerations. The relative benefits
received by the Company, on the one hand, and any of the Initial Purchasers (and
its related Indemnified Persons), on the other hand, shall be deemed to be in
the same proportion as the total proceeds from the Notes (net of discounts and
commissions but before deducting expenses), received by the Company bears to the
total discounts and commissions received by such Initial Purchaser, in each case
as set forth in the Offering Memorandum. The relative fault of the Company, on
the one hand, and such Initial Purchaser, on the other hand, shall be determined
by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact related to information supplied by the Company, on the one hand,
or by such Initial Purchaser, on the other, and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. The indemnity and contribution obligations of the Company
set forth herein shall be in addition to any liability or obligation the Company
may otherwise have to any Indemnified Person.

     The Company and the Initial Purchasers agree that it would not be just and
equitable if contribution pursuant to this Section 6(d) were determined by pro
                                                                           ---
rata allocation (even if the Initial Purchasers were treated as one entity for
- ----                                                                          
such purpose), or by any other method of allocation which does not take account
of the equitable considerations referred to in the immediately preceding
paragraph.  The amount paid or payable by an indemnified party as a result of
any Liabilities, referred to in the immediately preceding paragraph shall be
deemed to include, subject to the limitations set forth above, any legal or
other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim.  Notwithstanding the
provisions of this Section 6, none of the Initial Purchasers (and their related
Indemnified Persons) shall be required to contribute, in the aggregate, any
amount in excess of the amount by which the total discounts and commissions
applicable to the Notes purchased by such Initial Purchaser exceeds the amount
of any damages and related expenses which such 

                                       25
<PAGE>
 
Initial Purchaser (and its related Indemnified Persons), has otherwise been
required to pay or incur by reason of such untrue or alleged untrue statement or
omission or alleged omission. The Initial Purchasers' obligations to contribute
pursuant to this Section 6(d) are several in proportion to the respective
aggregate principal amount of Notes purchased by each of the Initial Purchasers
hereunder and not joint.

7.   Conditions to Initial Purchasers' Obligations.  The respective obligations
     ---------------------------------------------

Federal or state court of competent jurisdiction shall have been issued as of

possible change, in the rating accorded any of the Company's securities by any
nationally recognized statistical rating organization, as such term is defined
for purposes of Rule 436(g)(2) of the Act.

     (d) Since the earlier of the date hereof or the dates as of which
information is given in the Offering Memorandum, there shall not have been any
Material Adverse Change, (ii) since the date of the latest balance sheet

          Adverse Effect;

               (iii)  all of the outstanding shares of capital stock of, or

          accordance with the Indenture and paid for by you in accordance with

          Company in accordance with their terms and entitled to the benefits of
          the Indenture, except as such enforceability may be limited by
          applicable bankruptcy, insolvency, reorganization, moratorium,
          fraudulent transfer and other similar laws affecting the rights or

               (vi)   the Indenture, assuming due authorization, execution and

               (x)    each of the Registration Rights Agreement and the Escrow
          Agreement, assuming due authorization, execution and delivery thereof
          by the other parties thereto, will be a legal, valid and binding
          agreement of the Company, enforceable against the Company in
          accordance with its terms, except as rights of indemnity or
          contribution, or both, may be limited by state and Federal laws and
          except as such enforceability may be limited by applicable bankruptcy,
          insolvency, reorganization, moratorium, fraudulent transfer and other
          similar laws affecting the rights or remedies of creditors generally
          and to general principles of equity (regardless of whether enforcement
          is considered in a proceeding at law or in equity).  Each of the
          Registration Rights Agreement and the Escrow Agreement conforms in all
          material respects with the descriptions thereof in the Offering
          Memorandum;

               (xi)   neither the Company nor any Subsidiary is (A) in violation
          of its respective charter or bylaws or (B) in default in the
          performance of any obligation, bond, agreement, debenture, note or any
          other evidence of indebtedness, or any indenture, mortgage, deed of
          trust or other contract, lease or other instrument (identified to such
          counsel in writing by the Company as material to the Company and the
          Subsidiaries, taken as a whole) to which it is a 

                                       30

          party or by which it is bound, or to which any of the property or
          assets of any of them is subject;

               (xii)  the Escrow Agreement is sufficient to create a security
          interest in the financial assets described therein under the Uniform
          Commercial Code.  Assuming that the Escrow Agent continues to hold the
          financial assets described in the Escrow Agreement for the benefit of
          the Trustee in accordance with the Escrow Agreement, there has been
          granted to the Trustee a valid and perfected security interest in the
          financial assets described in the Escrow Agreement in accordance with
          the Uniform Commercial Code;

               (xiii)  all of the outstanding shares of capital stock of the
          Company have been duly authorized and validly issued and are fully
          paid and nonassessable;

               (xiv)  to the best of such counsel's knowledge, after due
          inquiry, neither the Company nor any of its Subsidiaries has violated
          any Environmental Laws, nor any Federal or state law relating to
          discrimination in the hiring, promotion or pay of employees nor any
          applicable Federal or state wages and hours laws, nor any provisions
          of the Employee Retirement Income Security Act, as amended, or the
          rules and regulations promulgated thereunder, which in each case might
          result in any Material Adverse Change;

               (xv) the Company and each of its Subsidiaries has such material
          permits, licenses, franchises and authorizations of governmental or
          regulatory authorities ("permits"), including, without limitation,
          under any applicable Environmental Laws, as are necessary to own,
          lease and operate its respective properties and to conduct its
          business as currently being conducted and as proposed to be conducted
          as described in the Offering Memorandum; to the best of such counsel's
          knowledge, after due inquiry, the Company and each of the Subsidiaries
          has fulfilled and performed all of its material obligations with
          respect to such permits and no event has occurred which allows, or
          after notice or lapse of time would allow, 

                                       31

          revocation or termination thereof or results in any other material
          permit, subject in each case to such qualification as may be set forth
          in the Offering Memorandum; and, except as described in the Offering
          Memorandum, such permits contain no restrictions that are materially
          burdensome to the Company or any of the Subsidiaries;

               (xvi)  (1) except as set forth in the Offering Memorandum, (i)
          the Company and each of the Subsidiaries has applied for or obtained
          all Authorizations of and from, and has made all declarations and
          filings with, all Governmental Authorities, including, without
          limitation, the FCC and each Applicable PUC necessary to conduct its
          business as it is currently being conducted and as it is proposed to
          be conducted as described in the Offering Memorandum, except to the
          extent that the failure to obtain, declare or file would not, singly
          or in the aggregate, have Material Adverse Effect, (ii) all such
          Authorizations are valid and in full force and effect, except where
          the failure of any such Authorization to be in full force and effect
          would not, singly or in the aggregate, have a Material Adverse Effect
          and (iii) the Company and each of the Subsidiaries is in compliance in
          all material respects with the rules and regulations of the FCC and
          all Applicable PUCs and the terms and conditions of all such
          Authorizations; (2) except for rulemaking proceedings of general
          applicability to the PCS industry not required to be described in the
          Offering Memorandum, there are no material legal or governmental
          proceedings pending before any Governmental Authority (except as such
          may be required under the Act or other securities or Blue Sky laws of
          the various states or by the NASD), including without limitation, the
          FCC or any Applicable PUC, to which the Company or any Subsidiary is a
          party or of which any property of the Company or any Subsidiary is the
          subject, and to the best of such counsel's knowledge, no such
          proceedings against the Company or any Subsidiary are threatened or
          contemplated; and (3) the execution, delivery and performance of this
          Agreement by the Company, the compliance by the Company with all the
          provisions thereof and the consummation of the transactions
          contemplated therein and in the Offering Memorandum, including,
          without limitation, the issuance and sale of the Notes to 

                                       32
<PAGE>
 
          the Initial Purchasers, (i) do not conflict with or result in a
          violation of the Telecommunications Act of 1996, the Communications
          Act of 1934, as amended, the rules or regulations of the FCC or any
          Applicable PUC, or any judgment, order or decree of any Governmental

          and "Management", insofar as such statements constitute a summary of
          legal matters, documents or proceedings referred to therein, fairly
          present the information called for with respect to such legal matters,
          documents and proceedings; and

               (xix)  assuming the accuracy of the representations and

          Agreement and of the Company in Section 5(ad) of this Purchase
          Agreement, the issuance and sale of the Notes to the Initial
          Purchasers and the offering, resale and delivery of the Notes by the

8.   Effective Date of Agreement, Defaults and Termination.  This Agreement
     -----------------------------------------------------                 
shall become effective upon the later of (i) the execution and delivery of this
Agreement by the parties hereto, and (ii) the delivery of the Offering
Memorandum to the Initial Purchasers for their use in connection with sales of
the Notes.

     This Agreement may be terminated at any time on or prior to the Closing
Date by the Initial Purchasers by notice to the Company if any of the following
has occurred:  (i) subsequent to the date of the Offering Memorandum or the date
of this Agreement, any Material Adverse Change which, in the judgment of DLJ,
impairs the investment quality of the Notes, (ii) any outbreak or escalation of
hostilities or other national or international calamity or crisis or material
adverse change in the financial markets of the United States or elsewhere or any
other substantial national or international calamity or emergency if the effect
of such outbreak, escalation, calamity, crisis or emergency would, in DLJ's
judgment, make it impracticable or inadvisable to market the Notes or to enforce
contracts for the sale of the Notes, (iii) any suspension or limitation of
trading generally in securities on the New York or American Exchanges or the
National Association of Securities Dealers Automated Quotation National Market,
PORTAL or the over-the-counter markets or any setting of minimum prices for

moratorium by either Federal or New York state authorities, (v) the taking of
any action by any Federal, state or local government or agency in respect of its
monetary or fiscal affairs that in DLJ's judgment has a material adverse effect
on the financial markets in the United States, and would, in DLJ's judgment,
make it impracticable or inadvisable to market the Notes or to enforce contracts
for the sale of the Notes, (vi) any securities of the Company shall have been
downgraded or placed on any "watch list" for possible downgrading or reviewed
for a possible change that does not indicate the direction of the possible
change by any "nationally recognized statistical rating organization," as such
term is defined for purposes of Rule 436(g)(2) of the Act, or (vii) the
enactment, publication, decree or other promulgation of any Federal, state or
local statute, regulation, rule or order of any court or other governmental
authority which would in the judgment of DLJ have a Material Adverse Effect or
make it inadvisable or impractical to market the Notes.

     If this Agreement shall be terminated by the Initial Purchasers pursuant to
clause (i), (vi) or (vii) of the second paragraph of this Section 8 or because
of the failure or refusal on the part of the Company to comply with the terms or
to fulfill 

                                       35

any of the conditions of this Agreement, the Company agrees to reimburse you for
all reasonable out-of-pocket expenses (including the reasonable fees and
disbursements of counsel) incurred by you. Notwithstanding any termination of
this Agreement, the Company shall be liable for all expenses which it agrees to
pay pursuant to Section 4 hereof. If this Agreement is terminated pursuant to
this Section 8, such termination shall be without liability of any Initial
Purchaser to the Company.

     If on the Closing Date either of the Initial Purchasers shall fail or
refuse to purchase the Notes which it has agreed to purchase hereunder on such
date and arrangements satisfactory to you and the Company for the purchase of
such Notes are not made within 48 hours after such default, this Agreement shall
terminate without liability on the part of the non-defaulting Initial Purchaser
and the Company, except as otherwise provided in this Section 8.  In any such
case that does not result in termination of this Agreement, either you or the
Company may postpone the Closing Date for not longer than seven (7) days, in
order that the required changes, if any, in the Offering Memorandum or any other
documents or arrangements may be effected.  Any action taken under this
paragraph shall not relieve a defaulting Initial Purchaser from liability in
respect of any default of any such Initial Purchaser under this Agreement.

     Escrow Account at any time shall be invested by the Escrow Agent in
     Temporary Cash Investments in accordance with the Company's written
     instructions from time to time to the Escrow Agent; provided, however, that
                                                         --------  -------

     interest on the outstanding Notes on each Interest Payment Date beginning
     on and including February 15, 1997, and through and including the Interest
     Payment Date on August 15, 1998; provided, further, however, that any such
                                      --------  -------  -------               
     written instruction shall specify the particular investment to be made,

     particular satisfies the requirements of the preceding proviso, shall

     2(d)(ii), if required, and shall be executed by any officer of the Company,
     provided, further, however, that in no event shall the Escrow Agent have
     --------  -------  -------
     an independent obligation to invest the funds deposited or held in the
     Escrow Account at any time absent written instructions from the Company.
     All Temporary Cash Investments shall be assigned to and held in the
     possession of, or, in the case of Temporary Cash Investments maintained in
     book entry form with the Federal Reserve Bank, transferred to a book entry
     account in the name of, the Escrow Agent, for the ratable benefit of the
     Trustee for the benefit of the holders of the Notes, with such guarantees
     as are customary, except that Temporary Cash Investments maintained in book
     entry form with the Federal Reserve Bank shall be transferred to a book
     entry account in the name of the Escrow Agent at the Federal Reserve Bank
     that includes only Temporary Cash Investments held by the Escrow Agent for
     its customers and segregated by separate recordation in the books and
     records of the Escrow Agent.

                    --------------------------------                         
     in the Escrow Account shall be made unless the Company has certified to the
     Escrow Agent and the Trustee that, upon such investment, the Trustee will
     have a first priority perfected security interest in the applicable
     investment.  A certificate as to a class of investments need not be issued
     with respect to individual investments in securities in that class if the
     certificate applicable to the class remains accurate with respect to such
     individual investments, which continued accuracy the Escrow Agent may
     conclusively assume.  On the Issue Date, and on each August 1 thereafter
     until the date upon which the balance of the Available Funds shall have
     been reduced to zero, each of the Trustee and the Escrow Agent shall
     receive an Opinion of Counsel (as such term is defined in the Indenture) to

              (iii)  Interest and Dividends.  All interest earned and dividends
                     ----------------------

     the Escrow Account as additional Collateral for the exclusive benefit of
     the Trustee for the ratable benefit of the holders of the Notes and shall
     be reinvested in accordance with the terms hereof at the Company's written
     instruction and subject to disbursement as provided herein.

              (iv)  Limitation on Escrow Agent's Responsibilities.  The Escrow
                    ---------------------------------------------             
     Agent's sole responsibilities under this Section 2 shall be (A) to retain
     possession of certificated Temporary Cash Investments (except, however,
     that Escrow Agent may surrender possession to the issuer of any such
     security for the purpose of effecting assignment, crediting interest, or
     reinvesting such security or reducing such security to cash) and to be the
     registered or designated owner of Temporary Cash Investments which are not
     certificated, (B) to follow the Company's written instructions given in
     accordance with Section 2(d)(i), (C) to invest and reinvest funds pursuant
     to this Section 2(d) and (D) to use reasonable efforts to reduce to cash
     such Temporary Cash Investments as may be required to fund any disbursement
     or payment in accordance with Section 3.  In connection with clause (A)
     above, the Escrow Agent will maintain continuous possession in the State of
     New York of certificated Temporary Cash Investments and cash included in
     the Collateral and will cause uncertificated Temporary Cash Investments to
     be registered in the book-entry system of, and transferred to an account of
     the Escrow Agent or a sub-agent of the Escrow Agent at, the Federal Reserve
     Bank of New York.  Except as provided in Section 6, the Escrow Agent 

                                       7
<PAGE>
 
     shall have no other responsibilities with respect to perfecting or
     maintaining the perfection of the Trustee's security interest in the
     Collateral and shall not be required to file any instrument, document or
     notice in any public office at any time or times, and (E) to keep accurate
     and detailed records of all investments, receipts, disbursements and other
     transactions involving the Escrow Account. In connection with clause (D)
     above the Escrow Agent shall not be required to reduce to cash any
     Temporary Cash Investments to fund any disbursement or payment in
     accordance with Section 3 in the absence of written instructions signed by
     an officer of the Company specifying the particular investment to
     liquidate. If no such written instructions are received, the Escrow Agent
     shall liquidate those Temporary Cash Investments having the lowest interest
     rate per annum, regardless of maturity, or if none such exist, those having
     the nearest maturity.

              (v)  Manner of Investment.  Funds deposited in the Escrow Account
                   --------------------                                        
     shall initially be invested in a manner such that the Company reasonably
     determines at such time that there will be sufficient funds available
     without any further investment by the Company to cover all interest due on
     the outstanding Notes, as such interest becomes due, for each Interest
     Payment Date occurring from the Issue Date and ending on (and including)
     August 15, 1998.  The Escrow Agent shall have no responsibility for
     determining whether funds held in the Escrow Account shall have been
     invested in such a manner so as to comply with the requirements of this
     clause (v).

              (e)  Substitution of Escrow Agent.  The Escrow Agent may resign by
                   ----------------------------                                 
giving no less than 30 days' prior written notice to  the Company and the
Trustee.  Such resignation shall take effect upon the later to occur of (i)
delivery of all funds and Temporary Cash Investments maintained by the Escrow
Agent hereunder and copies of all books, records, plans and other documents 

                                       8

Investments or this Agreement to a successor escrow agent mutually approved by
the Company and the Trustee (which approvals shall not be unreasonably withheld,
delayed or conditioned) and (ii) the Company, the Trustee and such successor
escrow agent entering into this Agreement or any written successor agreement no
less favorable to the interests of the holders of the Notes and the Trustee than
this Agreement; and the Escrow Agent shall thereupon be discharged of all
obligations under this Agreement and shall have no further duties, obligations
or responsibilities in connection herewith, except as set forth in Section 4. If
a successor escrow agent has not been appointed or has not accepted such
appointment within 30 days after notice of resignation is given to the Company,
the Escrow Agent may apply to a court of competent jurisdiction for the
appointment of a successor escrow agent.

              (f)  Escrow Account Statement.  At least 30 days prior to each
                   ------------------------                                 
Interest Payment Date, the Escrow Agent shall deliver to the Company and the
Trustee a statement setting forth with reasonable particularity the Collateral
then held by the Escrow Agent, including the balance of funds then in the Escrow
Account, and the manner in which such funds are invested (the "Escrow Account
                                                               --------------

Escrow Account shall be open to inspection and audit at reasonable times during
reasonable business hours by the Trustee and the Company or their respective
representatives.  The parties hereto irrevocably instruct the Escrow Agent that
on the first date upon which the balance in the Escrow Account (including the
holdings of all Temporary Cash Investments) is reduced to zero, the Escrow Agent
shall deliver to the Company and to the Trustee a notice that the balance in the
Escrow Account has been reduced to zero.

subject to the conditions described in Section 3(b), shall disburse the funds

          The Escrow Agent shall not be called upon to advise any party as to
selling or retaining, or taking or refraining from taking any action with
respect to, any securities or other property deposited hereunder.

          In the event of any ambiguity in the provisions of this Agreement with
respect to any funds or property deposited hereunder, the Escrow Agent shall be
entitled to refuse to comply with any and all claims, demands or instructions
with respect to such funds or property, and the Escrow Agent shall not be or
become liable for its failure or refusal to comply with conflicting claims,
demands or instructions.  The Escrow Agent shall be entitled to refuse to act
until either any conflicting or adverse claims or demands shall have been
finally deter-

                                       12

mined by a court of competent jurisdiction or settled by agreement between the
conflicting claimants as evidenced in a writing, satisfactory to the Escrow
Agent, or the Escrow Agent shall have received security or an indemnity
satisfactory to the Escrow Agent sufficient to save the Escrow Agent harmless
from and against any and all loss, liability or expense which the Escrow Agent
may incur by reason of its acting. The Escrow Agent may in addition elect in its
sole option to commence an interpleader action or seek other judicial relief or
orders as the Escrow Agent may deem necessary.

          No provision of this Agreement shall require the Escrow Agent to
expend or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder.

          5.  Indemnity.  The Company shall indemnify, hold harmless and defend
              ---------                                                        
the Escrow Agent and its directors, officers, agents, employees and controlling
persons, from and against any and all claims, actions, obligations, liabilities
and expenses, including defense costs, investigative fees and costs, legal fees,
and claims for damages, arising from the Escrow Agent's performance under this
Agreement, except to the extent that such liability, expense or claim is
attributable to the gross negligence or willful misconduct of the Escrow Agent
or any of the other foregoing persons.  Anything in this agreement to the
contrary notwithstanding, in no event shall the Escrow Agent be liable for
special, indirect or consequential loss or damage of any kind whatsoever,
including, but not limited to, lost profits, even if the Escrow Agent has been
advised of the likelihood of such loss or damage and regardless of the form of
action; provided, however, that in no event shall "lost profits" be construed to
        --------  -------                                                       
include interest or dividends on funds in the Escrow Account (including holdings
of Temporary Cash Investments) not earned due to the gross negligence or wilful
misconduct of the Escrow Agent in its performance of its duties hereunder.  The
provisions of this Section shall survive any termination, satisfaction or
discharge of this Agreement as well as the resignation or removal of the Escrow
Agent.

          6.  Grant of Security Interest; Instructions to Escrow Agent.
              -------------------------------------------------------- 

               (a)  The Company hereby irrevocably grants a first priority
security interest in and pledges, assigns and sets over to the Trustee for the
ratable benefit of the holders of the Notes all of the Company's right, title
and interest in the Escrow Account, and all property now or hereafter placed or
deposited in, or delivered to the Escrow Agent for placement or deposit in, the
Escrow Account, including, without limitation, all funds held therein, all
Temporary Cash Investments held by (or otherwise maintained in the name of) the
Escrow Agent pursuant to Section 2, and all proceeds thereof as well as all
rights of the Company under this Agreement (collectively, the "Collateral"), in
                                                               ----------      
order to secure all obligations and indebtedness of the Company under the Notes
and any other obligation, now or hereafter arising, of every kind and nature,
owed by the Company under the Indenture to the holders of the Notes or to the
Trustee.  The Escrow Agent hereby acknowledges the Trustee's security interest
as set forth above.  The Company shall take all actions necessary on its part to
insure the continuance of a first priority security interest in the Collateral
in favor of the Trustee in order to secure all such obligations and
indebtedness.

               (b)  The Company and the Trustee hereby irrevocably instruct the
Escrow Agent to, and the Escrow Agent shall, (i) (A) maintain sole dominion and
control over the Collateral, including any funds and Temporary Cash Investments
in the Escrow Account, for the benefit of the Trustee to the extent specifically
required herein, (B) maintain, or cause its agent within the State of New York
to maintain, possession of all certificated Temporary Cash Investments purchased
hereunder that are physically possessed by the Escrow Agent in order for the
Trustee to enjoy a continuous perfected first priority security interest therein
under the law of the State of New York (the Company hereby agreeing that in the
event any certificated Temporary Cash Investments are in the possession of the
Company or a third party, the Company shall use its best efforts to deliver all
such certificates to the Escrow Agent or in the case of a third party provide a
custodial letter agreement in form and sub-

                                       14
<PAGE>
 
stance satisfactory to the Company), (C) take all steps specified in writing by
the Company pursuant to paragraph (a) above to cause the Trustee to enjoy a
continuous perfected first priority security interest under the New York Uniform
Commercial Code and any applicable law of the State of New York in all Temporary
Cash Investments purchased hereunder that are not certificated and (D) maintain
the Collateral free and clear of all liens, security interests, safekeeping or
other charges, demands and claims against the Escrow Agent of any nature now or
hereafter existing in favor of anyone other than the Trustee; (ii) promptly
notify the Trustee if the Escrow Agent receives written notice that any person
other than the Trustee has a lien or security interest upon any portion of the
Collateral and (iii) in addition to disbursing amounts held in escrow pursuant
to any Payment Notice and Disbursement Requests given to it by the Trustee
pursuant to Section 3, upon receipt of written notice from the Trustee of the
acceleration of the maturity of the Notes, and direction from the Trustee to
disburse all Available Funds to the Trustee, as promptly as practicable disburse
all funds held in the Escrow Account to the Trustee and transfer title to all
Temporary Cash Investments held by the Escrow Agent hereunder to the Trustee.
The lien and security interest provided for by this Section 6 shall
automatically terminate and cease as to, and shall not extend or apply to, and
the Trustee shall have no security interest in, any funds disbursed by the
Escrow Agent to the Company pursuant to this Agreement to the extent not
inconsistent with the terms hereof. Notwithstanding any other provision
contained in this Agreement, the Escrow Agent shall act solely as the Trustee's
agent in connection with its duties under this Section 6; provided, however,
that the Trustee shall not be liable or responsible for the acts or omissions of
the Escrow Agent. The Escrow Agent shall not have any right to receive
compensation from the Trustee and is without any authority to obligate the
Trustee or to compromise or pledge its security interest hereunder. Accordingly,
the Escrow Agent is hereby directed to cooperate with the Trustee in the
exercise of its rights in the Collateral provided for herein.

          (c)  Any money and Temporary Cash Investments collected by the Trustee
pursuant to Section 

                                       15
<PAGE>
 
6(b)(iii) shall be applied as provided in Section 6.10 of the Indenture.

          (d)  Upon demand, the Company will execute and deliver to the Trustee
such instruments and documents as the Trustee may reasonably deem necessary or
advisable to confirm or perfect the rights of the Trustee under this Agreement
and the Trustee's interest in the Collateral.  The Trustee shall be entitled to
take all necessary action to preserve and protect the security interest created
hereby as a lien and encumbrance upon the Collateral; provided, however, that
absent written direction from the Company, the Trustee shall have no duty or
obligation to take any action pursuant to this subparagraph (d).

          (e)  The Company hereby appoints the Trustee as its attorney-in-fact
with full power of substitution to do any act which the Company is obligated
hereto to do, except that the Trustee shall not direct the investment of any
monies on deposit in the Escrow Account, and the Trustee may exercise such
rights as the Company might exercise with respect to the Collateral and take any
action in the Company's name to protect the Trustee's security interest
hereunder.  In addition to the rights provided under Section 6(b)(iii) hereof,
upon an Event of Default as defined in the Indenture and for so long as such
Event of Default continues, the Trustee may exercise in respect of the
Collateral, in addition to other rights and remedies provided for herein or
otherwise available to it, all the rights and remedies of a secured party under
the New York Uniform Commercial Code or other applicable law, and the Trustee
may also upon obtaining possession of the Collateral as set forth herein,
without notice to the Company except as specified below, sell the Collateral or
any part thereof in one or more parcels at public or private sale, at any
exchange, broker's board or at any of the Trustee's offices or elsewhere, for
cash, on credit or for future delivery, and upon such other terms as the Trustee
may deem commercially reasonable.  The Company acknowledges and agrees that any
such private sale may result in prices and other terms less favorable to the
seller than if such sale were a public sale.  The Company agrees that, to the
extent notice of sale shall be required by law, at least ten 

                                       16
<PAGE>
 
(10) days' notice to the Company of the time and place of any public sale or the
time after which any private sale is to be made shall constitute reasonable
notification. The Trustee shall not be obligated to make any sale regardless of
notice of sale having been given. The Trustee may adjourn any public or private
sale from time to time by announcement at the time and place fixed therefor, and
such sale may, without further notice, be made at the time and place to which it
was so adjourned.

          7.  Termination.  This Agreement shall terminate automatically ten
              -----------                                                   
(10) days following disbursement of all funds remaining in the Escrow Account
(including the proceeds of any Temporary Cash Investments), unless sooner
terminated by agreement of the parties hereto (in accordance with the terms
hereof, not in violation of the Indenture).  The Trustee may not agree to
terminate this Agreement unless it has received the consent of 100% of the
holders of all of the Notes outstanding; provided, however, that the obligations
of the Company under Section 2(c) and Section 5 (and any existing claims
thereunder) shall survive termination of this Agreement or the resignation or
removal of the Escrow Agent; provided, further, however, that until such tenth
day, the Company will cause this Agreement (or any permitted successor
agreement) to remain in effect and will cause there to be an escrow agent
(including any permitted successor thereto) acting hereunder (or under any such
permitted successor agreement).

          8.  Miscellaneous.
              ------------- 

               (a)  Waiver.  Any party hereto may specifically waive any 
                    ------ 
breach of this Agreement by any other party, but no such waiver shall be deemed
to have been given unless such waiver is in writing, signed by the waiving party
and specifically designating the breach waived, nor shall any such waiver
constitute a continuing waiver of similar or other breaches.

               (b)  Invalidity.  If for any reason whatsoever any one or more of
                    ---------- 
the provisions of this Agreement shall be held or deemed to be inoperative,
unenforceable or invalid in a particular case or in all cases, such
circumstances shall not have the effect of 

                                       17
<PAGE>
 
rendering any of the other provisions of this Agreement inoperative,
unenforceable or invalid, and the inoperative, unenforceable or invalid
provision shall be construed as if it were written so as to effectuate, to the
maximum extent possible, the parties' intent.

               (c)  Assignment.  This Agreement is personal to the parties
                    ----------
hereto, and the rights and duties of any party hereunder shall not be assignable
except with the prior written consent of the other parties. Notwithstanding the
foregoing, this Agreement shall inure to and be binding upon the parties and
their successors and permitted assigns.

               (d)  Benefit.  The parties hereto and their successors and
                    ------- 
permitted assigns, but no others, shall be bound hereby and entitled to the
benefits hereof; provided, however, that the holders of the Notes and their
permitted assigns shall be entitled to the benefits hereof and to enforce this
Agreement to the same extent as the Trustee, subject to the provisions of the
Indenture.

               (e)  Time.  Time is of the essence with respect to each provision
                    ----                                                        
of this Agreement.

               (f)  Entire Agreement; Amendments.  This Agreement and the
                    ----------------------------
Indenture contain the entire agreement among the parties with respect to the
subject matter hereof and supersede any and all prior agreements, understandings
and commitments, whether oral or written. This Agreement may be amended only in
accordance with Article IX of the Indenture and further by a writing signed by a
duly authorized representative of each party hereto.

               (g)  Notices.  All notices and other communications required or
                    -------

Agreement that may be instituted in any federal or state court in the State of
New York, or brought under federal or state securities laws, and acknowledges
that Bradley E. Sparks has accepted such designation, (ii) submits to the

that service of process upon Bradley E. Sparks (or any successor) and written
notice of said service to the Company (mailed or delivered to its Chief
Financial Officer at the Company's principal office in Arlington, Virginia),
shall be deemed in every respect effective service of process upon the Company
in any such suit or proceeding. The Company further agrees to take any and all

               (o)  Reliance on Oral Confirmation.  In the event funds transfer
                    -----------------------------                              
instructions are given (other than in writing at the time of execution of the
Agreement), whether in writing, by telecopier or otherwise, the Escrow Agent is
authorized to seek confirmation of such instructions by telephone call-back to
the person or persons designated on Schedule 1 hereto, and the Escrow Agent may
rely upon the confirmations of anyone purport-

                                       21
<PAGE>
 
ing to be the person or persons so designated. The persons and telephone numbers

acknowledged by the Escrow Agent. The parties to this Agreement acknowledge that
such security procedure is commercially reasonable.

               (p)  Reliance on Account Numbers.  It is understood that the
                    ---------------------------
Escrow Agent and the beneficiary's bank in any funds transfer may rely solely
upon any account numbers or similar identifying number provided by either of the
other parties hereto to identify (i) the beneficiary, (ii) the beneficiary's
bank, or (iii) an intermediary bank. The Escrow Agent may apply any of the
escrowed funds for any payment order it executes using any such identifying
number, even where its use may result in a person other than the beneficiary
being paid, or the transfer of funds to a bank other than the beneficiary's
bank, or an intermediary bank designated.

               (q)  Successor to Parties.  Any corporation into which the Escrow
                    --------------------                                        
Agent or the Trustee in their respective individual capacities may be merged or
converted or with which they may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Escrow Agent or the
Trustee in their respective individual capacities shall be a party, or any
corporation to which substantially all the corporate trust business of the
Escrow Agent or the Trustee in their respective individual capacities may be
transferred, shall be the Escrow Agent or Trustee, as the case may be, under
this Escrow Agreement without further act.

               (r)  Other Business with Escrow Agent.  Nothing contained herein
                    --------------------------------  
shall be deemed to prohibit the Company from conducting other business with the
Escrow Agent.
