amount of $[595,000,000] (the "Loans"). The Purchasers' obligation hereunder and
the obliga tions of the Lenders under the Loan Agreement are several and not
joint obligations and no Purchaser shall have any obligation under the Loan
Agreement and no liability to any Person for the performance or non-performance
by any Lender thereunder. Each Purchaser's obligation hereunder is a several and
not a joint obligation, and no Purchaser shall have any obligation or liability

any of the conditions specified in Section 4 shall not have been fulfilled to

          Section 5.17   Burdensome Obligations.  No Omnipoint Note Party is a
                         ----------------------
party to or bound by any franchise, agreement, deed, lease or other instrument,
or subject to any legal restriction which, in the opinion of the management of
Grand Parent or the Company, is so unusual or burdensome, in the context of its
business, as in the foreseeable future might materially and adversely affect or
impair the revenue or operating cash flow of such Omnipoint Note Party, or the
ability of such Omnipoint Note Party to perform obligations under the Note
Documents.  No Omnipoint Note Party presently anticipates that future

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

Omnipoint Note Party is presently a party to any transaction with any other
Omnipoint Note Party (other than for services as employees, officers and
directors), including any contract, agreement or other arrangement providing for
the furnishing of services to or by, providing for rental of real or personal

director or such employee or, to the knowledge of such Omnipoint Note Party, any
corporation, partnership, trust or other entity in which any officer, director,
or any such employee has a substantial interest or is an officer, director,
trustee or partner.  The Company has delivered a complete and correct copy of
the Expense Allocation Agreement to each Purchaser. No Omnipoint Note Party is a
party to any management, operating, license or other agreement providing for the

          Section 5.21   Employee Benefit Plans.
                         ----------------------

               (a) Each Employee Benefit Plan and each Plan has been maintained
     and operated in compliance in all material respects with the provisions of
     ERISA and, to the extent applicable, the IRC, including the provisions
     thereunder respecting prohibited transactions. Grand Parent, Company and
     each ERISA Affiliate has made all required contributions to each Employee
     Benefit Plan and each Multiemployer Plan. To the extent applicable, Grand
     Parent, Company and each ERISA Affiliate has heretofore delivered to the
     Purchasers the most recently completed annual report, Form 5500, with all
     required attachments, and actuarial statements required to be submitted
     under (S) 103(d) of ERISA, with respect to each Guaranteed Pension Plan.

               (b) Under each Employee Benefit Plan that is an employee welfare
     benefit plan within the meaning of (S) 3(1) or (S) 3(2) (b) of ERISA, no
     benefits are due unless the event giving rise to the benefit entitlement
     occurs prior to plan termination (except as required by Title I, Subtitle
     B, Part 6 of ERISA).  Grand Parent or an ERISA Affiliate, as appropriate,
     may terminate each such Plan at any time (or at any time

                                       16
<PAGE>

     subsequent to the expiration of any applicable bargaining agreement) in the
     discretion of any of Grand Parent or such ERISA Affiliate without liability
     to any Person.

               (c) Each contribution required to be made to a Guaranteed Pension
     Plan, whether required to be made to avoid the incurrence of an accumulated
     funding deficiency, the notice or lien provisions of (S) 302 (f) of ERISA,
     or otherwise, has been timely made.  No waiver of minimum funding standards
     or extension of amortization periods has been requested or received with
     respect to any Guaranteed Pension Plan.  No liability to the PBGC (other
     than required insurance premiums, all of which have been paid) has been
     incurred by Grand Parent or any ERISA Affiliate with respect to any Guaran
     teed Pension Plan and there has not been any ERISA Event, or any other
     event or condition that presents a material risk of termination of any
     Guaran  teed Pension Plan by the PBGC.  Neither Grand Parent nor any ERISA
     Affiliate has instituted or intends to institute proceedings to terminate a
     Guaranteed Pension Plan.  No event requiring notice to the PBGC under (S)
     302(f)(4)(A) of ERISA has occurred with respect to any Guaranteed Pension
     Plan and no amendment with respect to which security is required under (S)
     307 of ERISA has been made or is reasonably expected to be made to any
     Guaranteed Pension Plan.  Based on the latest valuation of each Guaran
     teed Pension Plan (which in each case occurred within 12 months prior to
     the date of this representation), and on the actuarial methods and
     assumptions employed for that valuation, the aggregate benefit liabilities
     of all such Guaranteed Pension Plans within the meaning of (S) 4001 of
     ERISA did not exceed the aggregate value of the assets of all such
     Guaranteed Pension Plans, disregarding for this purpose the benefit
     liabilities and assets of any Guaranteed Pension Plan with assets in excess
     of benefit liabilities.

               (d) Neither Grand Parent, the Company nor any ERISA Affiliate has
     incurred or expects to incur any material liability (including secondary
     liability) to any Multiemployer Plan as a result of a complete or partial
     withdrawal from such Multiemployer Plan under (S) 4201 of ERISA or as a
     result of a sale of assets described in (S) 4204 of ERISA.  Neither Grand
     Parent, the Company nor any ERISA Affiliate has been notified that any
     Multiemployer Plan is in reorganization or insolvent under and within the
     meaning of (S) 4241 or (S) 4245 of ERISA or that any Multiemployer Plan
     intends to terminate or has been terminated under (S) 4041A of ERISA.

     Omnipoint Loan Party has in its possession or to which it has access, and
     complete and accurate copies of each such report, or the results of each
     such investigation or audit, have been provided to the Purchasers.

          (d) Each Omnipoint Entity has filed all reports and returns re quired
     to be filed by such Omnipoint Entity under any applicable Environ  mental
     Laws.  Each Omnipoint Entity has obtained and is in compliance with all
     licenses, permits, registrations, certificates, consents, approvals or

                                      ---------------------
     applicable Environmental Laws.  No event has occurred and is continuing
     that requires, or after notice or lapse of time or both would require, any

     Entity (i) has received any notice asserting the absence of any
     Environmental Permit or (ii) has knowledge of any environmental law
     proposed or under consideration, which, if effective, could have a Material
     Adverse Effect.

                         ------------------
no Omnipoint Note Party is a party to any Material Contract or any agreement

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

               (a) If an Event of Default with respect to the Company described
     in paragraph (e) of Section 11 has occurred, all the Notes then outstanding
     shall automatically become immediately due and payable.

               (b) If any other Event of Default has occurred and is continuing,
     the Required Secured Creditors may at any time at its or their option, by
     notice or notices to the Company, declare all the Notes then outstanding to
     be immediately due and payable.

               (c) If any Event of Default described in paragraph (a) or (b) of
     Section 11 has occurred and is continuing, any Holder at the time
     outstanding affected by such Event of Default may at any time, at its or

                                       65
<PAGE>

     their option, by notice or notices to the Company, declare all the Notes
     held by it or them to be immediately due and payable.

               (d) Upon any Notes becoming due and payable under this Section
     12.1, whether automatically or by declaration, such Notes will forthwith
     mature and the entire unpaid principal amount of such Notes, plus (x) all
                                                                        -

     permitted by applicable law), shall all be immediately due and payable, in
     each and every case without presentment, demand, protest or further notice,
     all of which are hereby waived.  The Company acknowledges, and the parties
     hereto agree, that each holder of a Note has the right to maintain its
     investment in the Notes free from repayment by the Company (except as
     herein specifically provided for) and that the provision for payment of a
     Prepayment Premium by the Company in the event that the Notes are prepaid
     or are accelerated as a result of an Event of Default, is intended to
     provide compensation for the deprivation of such right under such
     circumstances.

          Section 12.2   Other Remedies.
                         --------------

          If any Default has occurred and is continuing, and irrespective of
whether any Notes have become or have been declared immediately due and payable
under Section 12.1, any Holder at the time outstanding may proceed to protect
and enforce the rights of such holder by an action at law, suit in equity or
other appropriate proceeding, whether for the specific performance of any
agreement contained herein or in any Note, or for an injunction against a
violation of any of the terms hereof or thereof, or in aid of the exercise of
any power granted hereby or thereby or by law or otherwise.

          Section 12.3   Rescission.
                         ----------

          At any time after any Notes have been declared due and payable
pursuant to clause (b) or (c) of Section 12.1, the Required Secured Creditors,
by written notice to the Company, may rescind and annul any such declaration and
its consequences if (a) the Company has paid all overdue interest on the Notes,
                     -
all principal of and Prepayment Premium, if any, on any Notes that are due and
payable and are unpaid other than by reason of such declaration, and all
interest on such overdue principal and Prepayment Premium, if any, and (to the
extent permitted by applicable law) any overdue interest in respect of the
Notes, at the

                                       66
<PAGE>

Default Rate, (b) all Defaults, other than non-payment of amounts that have
               -
become due solely by reason of such declaration, have been cured or have been
waived pursuant to Section 17.1, and (c) no judgment or decree has been entered
                                      -
for the payment of any monies due pursuant hereto or to the Notes. No rescission
and annulment under this Section 12.3 will extend to or affect any subsequent
Default or impair any right consequent thereon.

          Section 12.4   No Waivers or Election of Remedies, Expenses, etc.
                         --------------------------------------------------

          No course of dealing and no delay on the part of any Holder in
exercising any right, power or remedy shall operate as a waiver thereof or
otherwise prejudice such Holder's rights, powers or remedies.  No right, power
or remedy conferred by this Agreement or by any Note upon any holder thereof
shall be exclusive of any other right, power or remedy referred to herein or
therein or now or hereafter available at law, in equity, by statute or
otherwise.  Without limiting the obligations of the Company under Section 15.1,
the Company will pay to the Holder on demand such further amount as shall be
sufficient to cover all costs and expenses of such Holder incurred in any
enforcement or collection under this Section 12, including, without limitation,
reasonable attorneys' fees, expenses and disbursements.

Agency or any such nominee to a successor Clearing Agency or a nominee of such
successor Clearing Agency.  A Book-Entry Note will be exchanged by the Company
for Definitive Notes only in accordance with Section 9.18.

Notes, one Note may be in a denomination of less than $1,000,000, provided
                                                                  --------
further that any Note issued on the Closing Date in a denomination of less than
-------
$1,000,000 may be transferred.  Any transferee, by its acceptance of a Note
registered in its name (or the name of its nominee), or by acceptance of a
beneficial interest therein, shall be deemed to have made the representations
set forth in Article 6 and to have agreed to be bound by the provisions of the
Intercreditor Agreement and the other Note Documents.  Any transferor of a Note
or a beneficial interest therein shall notify any prospective purchaser that
such transferor may be relying on the exemption from Section 5 of the Securities
Act provided by Rule 144A.  The Paying Agent shall forward to the Company any
Notes surrendered to it for transfer, exchange or payment.

<PAGE>

"Holder" under this Agreement and, pursuant to the Joinder Agreement, shall (i)

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

          The Company shall require each Paying Agent to agree in writing that
such Paying Agent shall hold in trust for the benefit of Holders all assets held
by such Paying Agent for the payment of principal of, premium, if any, or
interest on, the Notes (whether such assets have been distributed to it by the
Company or any other obligor on the Notes), and shall notify the Holders in
writing of any Default in making any such payment.  The Company at any time may
require the Paying Agent to distribute all assets held by it to the Holders and
account for any assets disbursed and the Holders may at any time during the
continuance of any payment Default, upon written request to the Paying Agent,
require the Paying Agent to distribute all assets held by it to the Holders and

Interest Rate.  (a)  Subject to clause (b), the Paying Agent shall, as soon as
-------------
practicable, but in no event later than 1:00 p.m., Eastern time, two Business
Days before the effectiveness of each LIBO Rate, cause to be determined such

              -------------
the LIBO Rate for the initial interest period, based on the rate in effect two
Business Days before the Closing Date and inform the Company and each Holder of
such LIBO Rate for such interest period on the Closing Date. Each determination
of the LIBO Rate and the resulting Interest Rate shall be conclusive and binding
on the Company and each Holder in the absence of manifest error. In calculating
the Interest Rate, the Paying Agent may assume that the Applicable Margin is (i)
with respect to Base Rate, 2.25% per annum or (ii) with respect to LIBO Rate,
3.25% per annum until otherwise notified in writing by the Company. In the event
of any conflict between the instructions given to the Paying Agent by the
Required Holders and the Company pursuant to Section 13.7, the Paying Agent
shall be entitled to follow the instructions of the Company.

          (b) In the event that (i) the LIBOR Rate cannot be determined by the
Paying Agent or (ii) the Paying Agent receives written notice that any Holder is
unable lawfully for any reason whatsoever to hold its Note accruing interest at
the LIBO Rate plus the Applicable Margin, the Paying Agent shall determine the


                                       71
<PAGE>

Interest Rate based on the sum of the Base Rate and the Applicable Margin and

of clause (ii), the foregoing shall only apply with respect to that portion of
the Indebtedness outstanding under the Notes held by the affected Holder.

              Section 13.8 Nature of Duties.  The Paying Agent shall have no
                           ----------------
duties or responsibilities except those expressly set forth herein and in the
Note Documents.  Neither the Paying Agent nor any of its officers, directors,

the Paying Agent shall not have by reason of the Note Documents a fiduciary
relationship in respect of any Holder or any Omnipoint Entity; and nothing in
the Note Documents, expressed or implied, is intended to or shall be so

Paying Agent and the Company covenants and agrees to pay or reimburse the Paying
Agent upon its request for all reasonable expenses, disbursements and advances
incurred or made by or on behalf of it in accordance with any of the provisions
of this Agreement except to the extent any such expense, disbursement or advance
may arise from the Paying Agent's own gross negligence or bad faith.

          (b) To the extent the Paying Agent is not reimbursed and indemnified
by the Company in accordance with Section 15.1(c), the Holders will reimburse
and indemnify the Paying Agent, in proportion to their respective principal
amounts of Obligations, for and against any and all liabilities, obligations,

disbursements of any kind or nature whatsoever which may be imposed on, incurred
by or asserted against the Paying Agent in performing its duties hereunder or
under the Note Documents, or in any way relating to or arising out of the Note

                         -------------------------------------------
Paying Agent undertakes to perform such duties and only such duties as are

all or substantially all of its corporate trust business to another corporation,
the successor corporation without any further act shall become the Paying Agent
hereunder.  If a successor Paying Agent is not appointed within such 30 Business

invest any funds held by it.  The Paying Agent shall not be liable for any
action it takes or omits to take in good faith that it believes to be authorized
or within the rights or powers conferred upon it by this Agreement or the Notes.
The Paying Agent shall not be deemed to have notice or knowledge of any matter
unless a Responsible officer assigned to and working in the Paying Agent's
Corporate Trust Administration has actual knowledge thereof or unless written
notice thereof is received by the Paying Agent, Attention: Corporate Trust
Administration, and such notice references the Notes generally, the Company or
this Agreement.  As used herein the term "Responsible Officer" means any officer
within the Corporate Trust Administration of the Paying Agent (or any successor
group of the Paying Agent)

and complete authorization and protection in respect of any action taken,
suffered or omitted by it hereunder in good faith and in accordance with the
advice or opinion of such counsel. Notwithstanding Section 17.1, no amendment to
this Agreement or the Notes affecting the rights or obligations of the Paying

          Section 14.2   Home Office Payment.
                         -------------------

          So long as any Purchaser or its nominee shall be the holder of any
Note (other than a Book-Entry Note), and notwithstanding anything contained in
Section 14.1 or in such Note to the contrary, the Company will pay or cause the
Paying Agent to pay all sums becoming due on such Note for principal, Prepayment
Premium, if any, and interest by the method and at the address specified for
such purpose below such Purchaser's name in Schedule A, or by such other method
or at such other address as such Purchaser shall have from time to time
specified to the Company in writing for such purpose, without the presentation
or surrender of such Note or the making of any notation thereon, except that
upon written request of the Company made concurrently with or reasonably
promptly after payment or prepayment in full of any Note, such Purchaser shall
surrender such Note for cancellation, reasonably promptly after any such
request, to the

                                       74
<PAGE>

Purchaser or its nominee such Purchaser will, at its election, either endorse
thereon the amount of principal paid thereon and the last date to which interest
has been paid thereon or surrender such Note to the Company in exchange for a
new Note or Notes pursuant to Section 13.2. The Company will afford the benefits
of this Section 14.2 to any Institutional Investor that is the direct or
indirect transferee of any Note purchased by any Purchaser under this Agreement
and that has made the same agreement relating to such Note as such Purchaser has
made in this Section 14.2. Notwithstanding the foregoing, the Company may
deliver any interest payment to the Paying Agent.

     found in a final, non-appealable judgment by a court of competent
     jurisdiction to have resulted from such Indemnified Party's gross
     negligence or willful misconduct. In the case of any investigation,

pursuant to this Agreement that is proprietary in nature and that was clearly
marked or labeled or otherwise adequately identified when received by such
Purchaser as being confidential information of the Company or such Subsidiary,
provided that such term does not include information that (a) was publicly known
--------                                                   -

such Purchaser other than through disclosure by the Company or any Subsidiary or
(d) constitutes financial statements delivered to such Purchaser under Section
 -
7.1 that are otherwise publicly available.  Each Purchaser will maintain the
confidentiality of such Confidential Information in accordance with procedures
adopted by such Purchaser in good faith to protect confidential information of
third parties delivered to such Purchaser; provided that any Purchaser may
                                           --------
deliver or disclose Confidential Information to (i) its directors, officers,
                                                 -
employees, agents, attorneys and affiliates,  (to the extent such disclosure

Notes), (ii) its financial advisors and other professional advisors who agree to
         --
hold confidential the Confidential Information substantially in accordance with
the terms of this Section 20, (iii) any other holder of any Note, (iv) any

                                     -

such Person has agreed in writing prior to its receipt of such Confidential
Information to be bound by the provisions of this Section 20), (vi) any federal
                                                                --
or state regulatory authority having jurisdiction over any Purchaser, (vii) the
                                                                       ---

                                                 ----
such delivery or disclosure may be necessary or appropriate (w) to effect
                                                             -
compliance with any law, rule, regulation or order applicable to any Purchaser,
(x) in response to any subpoena or other legal process, (y) in connection with
 -                                                       -
any litigation to which any Purchaser is a party or (z) if an Event of Default
                                                     -
has occurred and is continuing, to the extent any Purchaser may reasonably
determine such delivery and disclosure to be necessary or appropriate in the
enforcement or for the protection of the rights and remedies under its Notes and
this Agreement. Each holder of a Note, by its acceptance of a Note, will be
deemed to have agreed to be bound by and to be entitled to the benefits of this
Section 20 as though it were a party to this Agreement. On reasonable request by
the Company in connection with the delivery to any holder of a Note of
information required to be delivered to such holder under this Agreement or
requested by such holder (other than a holder that is a party to this Agreement
or its nominee), such holder will enter into an agreement with the Company
embodying the provisions of this Section 20.

 21  SUBSTITUTION OF PURCHASER.

          Each Purchaser shall have the right to substitute any one of its
Affiliates as the purchaser of the Notes that such Purchaser has agreed to
purchase hereunder, by written notice to the Company, which notice shall be
signed by both such Purchaser and such Affiliate, shall contain such Affiliate's
agreement to be bound by this Agreement and shall contain a confirmation by such
Affiliate of the accuracy with respect to it of the representations set forth in
Section 6.  Upon receipt of such notice, wherever the word "Purchaser" is used
in this Agreement (other than in this Section 21), such word shall be deemed to
refer to such Affiliate in lieu of such Purchaser.  In the event that such
Affiliate is so substituted as a Purchaser hereunder and such Affiliate
thereafter transfers to such Purchaser all of the Notes then held by such
Affiliate, upon receipt by the Company of notice of such transfer, wherever the
word "Purchaser" is used in this Agreement (other than in this Section 21), such
word shall no longer be deemed to refer to such Affiliate, but shall refer to
such Purchaser, and such Purchaser shall have all the rights of an original
holder of the Notes under this Agreement.

including the additional days elapsed in the computation of the interest payable
on such next succeeding Business Day.

          Section 22.3     Severability.  Any provision of this Agreement that
                           ------------
is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof, and any
such prohibition or unenforceability in any jurisdiction shall (to the full
extent permitted by law) not invalidate or render unenforceable such provision
in any other jurisdiction.

          Section 22.4     Construction.  Each covenant contained herein shall
                           ------------
be construed (absent express provision to the contrary) as being independent of
each other covenant contained herein, so that compliance with any one covenant
shall not (absent such an express contrary provision) be deemed to excuse
compliance with any other covenant.  Where any provision herein refers to action
to be taken by any Person, or which such Person is prohibited from taking, such
provision shall be applicable whether such action is taken directly or
indirectly by such Person.

          Section 22.5   Counterparts.  This Agreement may be executed in any
                         ------------

together shall constitute one instrument.  Each counterpart may consist of a
number of copies hereof, each signed by less than all, but together signed by
all, of the parties hereto.

          Section 22.6   Governing Law.  This Agreement shall be construed and
                         -------------
enforced in accordance with, and the rights of the parties shall be governed by,
the law of the State of New York excluding choice-of-law principles of the law
of such State that would require the application of the laws of a jurisdiction
other than such State.

          Section 22.7   Grand Parent Not a Guarantor.  The parties hereto
                         ----------------------------
acknowledge and agree that Grand Parent shall be a party hereto solely for the
purposes of providing the covenants and representations expressly specified
herein, and shall not be a guarantor of the Obligations of any Loan Party under
the Loan Documents.

          Section 22.8   Appointment of Collateral Agent.  Each Holder hereby
                         -------------------------------
appoints and authorizes the Collateral Agent to take such action as agent on its
behalf and to exercise such powers and discretion under the Intercreditor
Agreement and the Collateral Documents as are delegated to the Collateral Agent
by the terms thereof, together with such powers and discretion as are reasonably
incidental thereto.
