                                    GENERAL

ITEM 1.  GENERAL INFORMATION.

     (a) Each of Arch Wireless Holdings, Inc. (the "Corporation"), Arch
Wireless, Inc. (the "Parent"), Arch Wireless Communications, Inc. ("AWCI"),
Paging Network Canadian Holdings, Inc. ("PNCH"), PageNet SMR Sub, Inc.
("PNSMR"), ArchTel, Inc., Arch Connecticut Valley, Inc., Benbow Investments,
Inc., MobileMedia Communications, Inc., Mobile Communications Corporation of
America, Paging Network, Inc., PageNet, Inc., Paging Network of America, Inc.,
Paging Network of Colorado, Inc., Paging Network of Northern California, Inc.,
Paging Network of Michigan, Inc., Paging Network Finance Corp., Paging Network
International, Inc. and Paging Network of San Francisco, Inc. are corporations.
Arch Communication Enterprises, LLC and MobileMedia License Co., L.L.C. are
limited liability companies. Except for the Corporation, each of the foregoing
entities shall be referred to herein collectively as the "Guarantors."

     (b) The Corporation and each of the Guarantors (other than Arch Connecticut
Valley, Inc.) are organized under the laws of the State of Delaware. Arch
Connecticut Valley, Inc. is organized under the laws of the Commonwealth of
Massachusetts. The mailing address for the Corporation and each of the
Guarantors is c/o Arch Wireless, Inc., 1800 West Park Drive, Suite 250,
Westborough, Massachusetts 01581.

ITEM 2.  SECURITIES ACT EXEMPTION APPLICABLE.

     The Corporation intends to commence a solicitation (the "Solicitation") of
acceptances of a proposed joint reorganization plan (the "Plan") of the
Corporation, the Parent and their respective debtor subsidiaries as set forth in
the Plan, pursuant to which the Corporation intends to issue 10% Senior
Subordinated Secured Notes due 2007 (the "New Senior Notes") and 12%
Subordinated Secured Compounding Notes due 2009 (the "New Subordinated Notes"
and, collectively with the New Senior Notes, the "New Notes") under Title 11 of
the United States Code (the "Bankruptcy Code"). The Chapter 11 cases of the
Corporation and the Parent and certain of its subsidiaries are presently pending
before the United States Bankruptcy Court for the District of Massachusetts
(Western Division) (the "Bankruptcy Court"). The New Senior Notes will be issued
under an indenture (the "Indenture") which is the subject of this application. A
copy of the Disclosure Statement relating to the Plan (which includes the Plan
as Exhibit A thereto), which was approved by an order of the Bankruptcy Court
dated March 13, 2002, is attached hereto as Exhibit T3E.

     Under the Plan, on the date on which the Corporation consummates the Plan
(the "Effective Date"), or as soon as practicable thereafter, the holders of
Allowed Bank Secured Claims and Allowed USAM Secured Note Claims (each as
defined in the Plan) shall receive New Notes in partial satisfaction of such
claims. The New Senior Notes will be due five years after the Effective Date.
The New Subordinated Notes will be due seven years after the Effective Date. The
Corporation anticipates initially issuing $200,000,000 in New Senior Notes and
$100,000,000 in New Subordinated Notes under the Plan.

     There has not been, nor is there going to be, any sales of New Notes by the
Corporation or by or through an underwriter at or about the same time as the
Plan or the offering, exchange and distribution of the New Notes. The
Corporation has not paid or given, and will not pay or give, directly or
indirectly, any commission or other remuneration to any broker, dealer, salesman
or other person for solicitation in connection with any aspect of the Plan.

     The Corporation believes that the issuance of the New Notes is exempt from
the registration requirements of the Securities Act of 1933, as amended (the
"Securities Act"), and state securities and "blue sky" laws pursuant to Section
1145(a)(1) of Title 11 of the Bankruptcy Code. Generally, Section 1145(a)(1) of
the Bankruptcy Code exempts the offer and sale of securities under a bankruptcy
plan of reorganization from registration under the Securities Act and under
equivalent state securities and "blue sky" laws if the following requirements
are satisfied: (1) the securities are issued by the debtor (or an affiliate
participating in a joint plan with the debtor or the debtor's successor) under a
plan of reorganization; (2) the recipients of the securities hold a pre-petition
or administrative claim against the debtor or an interest in the debtor; and (3)
the securities are issued entirely in exchange for the recipient's claim against
or interest in the debtor or
                                        1


are issued "principally" in such exchange and "partly" for cash or property. The
Corporation believes that the offer of the New Notes under the Solicitation and
the exchange of New Notes under the Plan will satisfy the requirements of
Section 1145(a)(1) of the Bankruptcy Code and, therefore, such offer is exempt
from the registration requirements referred to above.

                                  AFFILIATIONS

ITEM 3.  AFFILIATES.

     (a) Set forth below is a list of the Parent and all direct and indirect
subsidiaries of the Parent and the Corporation (the "Subsidiaries" and each a
"Subsidiary"). Unless stated otherwise, each Subsidiary is wholly owned by the
Corporation. The Parent, the Corporation and each Subsidiary will continue its
corporate existence unchanged after the Effective Date.

     On the Effective Date, AWCI shall issue 100 shares of New AWCI Common Stock
to the person designated by the Collateral Agent and the USAM Trustees pursuant
to Article III.B.2(a) and (c) of the Plan, which shall constitute all of the
issued and outstanding capital stock of AWCI immediately following the Effective
Date.

     On the Effective Date, PNCH shall issue 100 shares of New PNCH Common Stock
to the person designated by the Collateral Agent and the USAM Trustees in
accordance with the provisions of Article III.B.2(a) and (c) of the Plan, which
shall constitute all of the issued and outstanding capital stock of PNCH
immediately following the Effective Date.

     On the Effective Date, PNSMR shall issue 100 shares of New PNSMR Common
Stock to the person designated by the Collateral Agent and the USAM Trustees in
accordance with the provisions of Artcile III.B.2(a) and(c) of the Plan, which

immediately following the Effective Date.

     As of the Effective Date, the information with respect to each authorized
class of securities of the other Guarantors will remain as set forth in this
Item 7(a).

     (b)  The current holders of common stock are entitled to one vote for each
share held of record on all matters voted upon by stockholders (or in case of
limited liability companies to vote pro rata to the interests held), and a
majority vote is required for all action to be taken by stockholders. So long as
at least 50% of the Series C Preferred Stock of the Parent remains outstanding,
the holders of the Series C Preferred Stock have the right, voting as a separate
class, to designate one member of the Parent's Board of Directors and one member
of AWCI's Board of Directors. On all other matters, the Parent's Series C
Preferred Stock and common stock vote together as a single class. Each shares of
Series C Preferred Stock is entitled to as many votes as the number of shares of
common stock into which it is convertible (8.0182) as of December 6, 2001, the
date on which the Parent and its domestic subsidiaries filed voluntary
petititions for relief under Chapter 11 of the Bankruptcy Code with the
Bankruptcy Court. The Parent's Series F Preferred Stock does not have any voting
rights. Cumulative voting of shares is not allowed. No holder of any other
securities of the Corporation or any Guarantor is entitled to vote on matters
submitted to a vote of stockholders. The voting rights of the New AWHI Common
Stock and the new common stock to be issued by the Parent on the Effective Date
will be identical to the voting rights of the Corporation's and the Parent's (as
the case may be) current common stock described in this Item 7(b). Under the
Plan, existing common stock of the Corporation, the Parent, AWCI, PNCH and PNSMR
will be cancelled as of the Effective Date.

     of the Subsidiaries or any combination thereof (which shall not be fully
     covered by insurance without taking into account any applicable
     deductibles) and the same shall remain undischarged or unbonded for a
     period of 30 consecutive days during which execution shall not be
     effectively stayed;

          (11) any Note Document shall cease, for any reason, to be in full
     force and effect, or any Note Party shall so assert in writing or shall
     disavow any of its obligations thereunder; or

          (12) an Event of Default under and as defined in the Junior Indenture
     or any Credit Agreement shall have occurred.

     If a Default or an Event of Default occurs and is continuing and is known
to the Trustee, the Trustee shall mail to each Holder of the Notes notice of the
Default or Event of Default within 30 days after the occurrence thereof, or, if
later, promptly upon the Trustee obtaining knowledge thereof. Except in the case
of a Default or an Event of Default in payment of principal of or interest on
any Notes, the Trustee may withhold the notice to the Holders of such Notes if
its Board of Directors, executive committee or a committee of its trust officers
in good faith determines that withholding the notice is in the interest of the
Holders of the Notes.

     If an Event of Default (other than an Event of Default described in clause
(h) or (i) of Section 4.01 of the Indenture), shall have occurred and be
continuing, the Trustee or the Majority Noteholders may, by notice to the
Corporation, declare the Notes then outstanding to be due and payable in whole
(or in part, in which case any principal not so declared to be due and payable
may thereafter be declared to be due and payable), and thereupon the principal
of the Notes so declared to be due and payable, together with accrued interest
thereon and all fees and other obligations of each Note Party accrued under the
Note Documents, shall become due and payable immediately, without presentment,
demand, protest or other notice of any kind, all of which are hereby waived by
the Corporation. In case of any Event of Default described in clause (h) or (i)
of Section 4.01 of the Indenture, the principal of the Notes then outstanding,
together with accrued interest thereon and all fees and other obligations of
each Note Party accrued under the Note Documents, shall automatically become due
and payable, without presentment, demand, protest or other notice of any kind,
all of which are hereby waived by the Corporation; provided, however, that so
long as any Senior Debt is outstanding, the acceleration shall not be effective
until the earlier of (i) an acceleration of any Senior Debt or (ii) five
Business Days after receipt by the Corporation of written notice of the
acceleration of the Notes.

     The Holders of the Notes shall not have the independent right to direct the
time, method or place of conducting any remedy available to the Trustee or
exercising any trust or power conferred upon the Trustee or, on behalf of all
Holders of Notes, to consent to the waiver of any past Default or Event of
Default or its consequences. All decisions regarding the declaration of an Event
of Default, the acceleration of the Notes, the waiver of any Defaults and Events
of Default, and the direction of the Collateral Agent and the Trustee with
respect to the exercise of rights and remedies against the Corporation, the
Guarantors and the Collateral

                                        17


shall be made by the Majority Noteholders. These limitations do not apply to a
suit instituted by a Holder of a Note for enforcement of payment of any amounts
then due as an unsecured claimant.

(b) AUTHENTICATION AND DELIVERY OF THE NOTES UNDER THE INDENTURE AND APPLICATION
    OF PROCEEDS THEREOF.

     The Notes to be issued under the Indenture may from time to time be
executed on behalf of the Corporation by one officer who shall sign the Notes
for the Corporation by manual or facsimile signature. If an officer whose
signature is on a Note no longer holds that office at the time a Note is
authenticated, the Note shall nevertheless be valid. A Note shall not be valid
until authenticated by the manual signature of the Trustee. The signature shall
be conclusive evidence that the Note has been authenticated under the Indenture.

     The Trustee shall, upon a receipt of a Company Order requesting that notes
be authenticated by the Trustee, authenticate Notes for original issue.

     The Trustee may appoint an authenticating agent acceptable to the
Corporation to authenticate Notes. An authenticating agent may authenticate
Notes whenever the Trustee may do so. Each reference in the Indenture to
authentication by the Trustee includes authentication by such agent. An
authenticating agent has the same rights as an Agent to deal with Holders or an
Affiliate of the Corporation.

     There will be no proceeds (and therefore no application of such proceeds)
from the issuance of the Notes because the Notes will be issued in partial
satisfaction of the obligations owing to the Holders.

(c) RELEASE OF ANY NOTE COLLATERAL SUBJECT TO THE LIEN OF THE INDENTURE.

     The Collateral shall be released from the Lien of the Security Documents as
expressly provided therein or in connection with any transaction permitted by
Section 10.11 of the Indenture (Asset Sales).

     Section 11.04 of the Indenture contains the general provisions for the
release of Collateral from the Lien of the Security Documents in accordance with
the TIA, including delivery of the certificates and opinions of fair value
required by Section 314(d) of the TIA. Section 11.05(a) of the Indenture,
however, permits the release of Collateral in connection with the (i) sale,
disposition or use of inventory, (ii) sale or disposition of obsolete or worn
out fixtures or equipment, (iii) collection, liquidation or disposition of
accounts receivable, (iv) renegotiation and termination of leasehold interests,
and (v) granting of easements and rights of way on certain properties that do
not secure any monetary obligations and do not materially affect the value of
the affected property, all in the ordinary course of the Corporation's or the
Guarantors' business and in each case without the delivery by the Corporation of
the certificates and opinions required by Section 314(d) of the Act. In lieu
thereof and in order to protect the interests of purchasers of the Notes and
allow the Corporation to carry on its regular business in the ordinary course,
Section 11.05(b) of the Indenture requires the Corporation and the Guarantors to
deliver semi-annually to the Trustee and the Collateral Agent a certificate
verifying that all such sales or uses of inventory, collections and other
dispositions of accounts receivable and any other disposition or transaction
contemplated by Section 11.05(a) of the Indenture, during the applicable
six-month period, were made in the ordinary course of the Corporation's and the
Guarantors' business and that all proceeds from such activities were used by the
Corporation and the Guarantors in the ordinary course of their business or
otherwise as permitted by the Indenture. In addition, pursuant to Section 10.27
of the Indenture, the Corporation is required to furnish the Trustee unaudited
quarterly and audited annual consolidated financial statements meeting the
requirements imposed on reporting companies under Section 13 or 15(d) of the
Securities Exchange Act of 1934, as amended, whether or not the Corporation is
then a reporting corporation. In the Corporation's view, based on the foregoing,
compliance with the certificate and opinion requirements of Section 314(d) of
the TIA in the context of sales or uses of inventory, collections and other
dispositions of accounts receivable and any other disposition or transaction
contemplated by Section 11.05(a) of the Indenture in the ordinary course of the
Corporation's or the Guarantors' business is not necessary for the protection of
purchasers of the Notes and such failure by the Corporation to so comply would
not be inconsistent with the purposes fairly intended to be served by Section
314(d) of the TIA.

                                        18


     The release of any Collateral from the Lien of the Indenture and of the
Security Documents pursuant to the terms of the Security Documents or the
Indenture will not be deemed to impair the security under the Indenture in
contravention of the provisions thereof.

(d) SATISFACTION AND DISCHARGE OF THE INDENTURE.

     Upon the written request of the Corporation, the Indenture will cease to be
of further effect, and the Trustee, at the expense of the Corporation, will
execute proper instruments acknowledging satisfaction and discharge of the
Indenture, when:

          (1) either

             (a) all the Notes theretofore authenticated and delivered (other
        than (i) Notes which have been mutilated, destroyed, lost or stolen and
        which have been replaced or paid as provided in Section 2.10 of the
        Indenture) have been delivered to the Trustee for cancellation; or

             (b) all Notes not theretofore delivered to the Trustee for
        cancellation have come due and payable, by reason of the making of a
        notice of redemption or will otherwise become due and payable within one
        year and the Corporation has irrevocably deposited or caused to be
        deposited with the Trustee funds in trust for the purpose in an amount
        sufficient to pay and discharge the entire Indebtedness on such Notes
        not theretofore delivered to the Trustee for cancellation, for principal
        and interest to the date of such deposit (in the case of Notes which
        have become due and payable) or to the Stated Maturity or Redemption
        Date, as the case may be;

          (2) no Default or Event of Default shall have occurred and be
     continuing on the date of such deposit or shall occur as a result of such
     deposit, and such deposit will not result in a breach or violation of, or
     constitute a default under, any other instrument to which the Corporation
     is a party or by which the Corporation is bound;

          (3) the Corporation has paid or caused to be paid all other sums
     payable hereunder by the Corporation;

          (4) the Corporation has delivered irrevocable instructions to the
     Trustee under the Indenture to apply the deposited money and/or
     non-callable Government Securities toward the payment of the Notes at
     maturity or the redemption date, as the case may be; and

          (5) the Corporation has delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that all conditions
     precedent herein provided for relating to the satisfaction and discharge of
     the Indenture have been complied with.

     Notwithstanding the satisfaction and discharge of the Indenture, the
obligations of the Corporation to the Trustee under Section 5.07 of the
Indenture and, the obligations of the Trustee under Section 3.02 and the last
paragraph of Section 10.03 of the Indenture shall survive.

     The Corporation may at any time, for the purpose of obtaining the
satisfaction and discharge of the Indenture or for any other purpose, pay, or by
Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Corporation or such Paying Agent, such sums to be held by the
Trustee upon the same trusts as those upon which such sums were held by the
Corporation or such Paying Agent; and, upon such payment by any Paying Agent to
the Trustee, such Paying Agent shall be released from all further liability with
respect to such money.

     Any money deposited with the Trustee or any Paying Agent, or then held by
the Corporation, in trust for the payment of the principal of or interest on any
Note and remaining unclaimed for two years after such principal or interest has
become due and payable shall be paid to the Corporation on Company Request, or
(if then held by the Corporation) shall be discharged from such trust; and the
Holder of such Note shall thereafter, as an unsecured general creditor, look
only to the Corporation for payment thereof, and all liability of the Trustee or
such Paying Agent with respect to such trust money, and all liability of the
Corporation as trustee thereof, shall thereupon cease; provided, however, that
the Trustee or such Paying Agent, before being

                                        19


required to make any such repayment, may at the expense of the Corporation cause
to be published once, in a newspaper published in the English language,
customarily published on each Business Day and of general circulation in the
Borough of Manhattan, The City of New York, New York, notice that such money
remains unclaimed and that, after a date specified therein, which shall not be
less than 30 days from the date of such publication, any unclaimed balance of
such money then remaining will be repaid to the Corporation.

(e) THE EVIDENCE REQUIRED TO BE FURNISHED BY THE CORPORATION TO THE TRUSTEE AS
TO COMPLIANCE WITH THE CONDITIONS AND COVENANTS PROVIDED FOR IN THE INDENTURE.

     The Corporation will deliver to the Trustee, within 90 days after the end
of each Fiscal Year of the Corporation ending after the date hereof, an
Officers' Certificate, stating whether or not to the knowledge of the signers
thereof the Corporation is in compliance with all the terms, provisions,
covenants and conditions of the Indenture and if the Corporation shall be in
Default under the Indenture, specifying all such Defaults and the nature and
status thereof of which they may have knowledge and including the information
referred to in clause (i) in the next paragraph.

     The Corporation will deliver to the Trustee within 45 days after the end of
each Fiscal Quarter of any Fiscal Year, an Officers' Certificate (i)
demonstrating compliance with each of the financial covenants contained in
Article X of the Indenture which is tested on a quarterly basis, and (ii)
stating that no Default or Event of Default has occurred and is continuing or,
if a Default or Event of Default has occurred and is continuing, stating the
nature thereof and the action which the Corporation proposes to take with
respect thereto.

     The Corporation will, so long as any of the Notes are Outstanding, deliver
to the Trustee, within five Business Days of becoming aware of any Default or
Event of Default in the performance of any covenant, agreement or condition in
the Indenture, an Officers' Certificate specifying such Default or Event of
Default.

ITEM 9.  OTHER OBLIGORS.

Guarantors is attached as Annex A hereto.
