is currently owed by the Seller pursuant to the Covad Contract for pre-

Buyer shall deliver or cause to be delivered by wire transfer or by a
certified or cashier's check, the amount of Three Hundred Thousand and 00/00
United States Dollars (US $300,000.00) (the "Security Deposit") into the care
of Swidler Berlin Shereff Friedman, LLP as escrow agent (the "Escrow Agent")
pursuant to the terms and conditions of this Section 2(a) and of an escrow

Assets shall be:  TWO Million AND 00/00 UNITED STATES DOLLARS  (US
$2,000,000.00) (the "Purchase Price").  The Purchase Price is in addition to
and separate from the payment by Buyer to Covad of the Covad Cure Amount

reduction of Seller's liability to Covad), and the Purchase Price is payable

          (i)    At the Closing (as defined below), Buyer shall deliver to
Seller by wire transfer in immediately available funds to an account

deliver to the Escrow Agent a Mutual Consent Notice (as defined in the Escrow
Agreement), instructing the Escrow Agent to wire on the Closing Date the
amount of the Security Deposit, plus any interest accrued thereon, to the
account of Seller as designated in the Mutual Consent Notice.

         (iii)    If the amount paid by Buyer to Covad in connection with the
assignment and assumption of the Covad Agreement to Buyer hereunder (the
"Actual Covad Cure Payment") is less than the Covad Cure Amount, Buyer shall
also pay to Seller an amount equal to fifty percent (50%) of the difference
between the Covad Cure Amount and the Actual Covad Cure Payment.

     (c)    The Parties agree that the Purchase Price shall be allocated as
set forth on Schedule 2(c) attached hereto and that the Parties will file all
Federal and state income tax returns and all other forms and returns,
including Internal Revenue Service Form 8594, in accordance with the
allocation set forth on Schedule 2(c).

Acquired Assets.

4.    REPRESENTATIONS AND WARRANTIES OF SELLER

     Seller hereby represents, warrants and covenants to Buyer as follows:

corporations duly organized, validly existing and in good standing under the
laws of the State of Delaware and the Commonwealth of Virginia, respectively.
The execution and delivery by Seller of this Agreement to Buyer and the sale
contemplated hereby has been duly and validly authorized by any and all
necessary action on the part of Seller and its stockholders, and Seller shall
deliver to Buyer, at or prior to the execution hereof, copies, certified by
Seller's Secretary, of the minutes of the meeting of its Board of Directors
and stockholders at which such authority was granted. Subject to Bankruptcy
Court approval, this Agreement and the documents executed pursuant to this
Agreement (collectively the "Definitive Documents")  to which it is a party
have been duly and validly executed by Seller and, assuming due authorization,
execution and delivery by the Seller of the Definitive Documents to which it
is a party, such Definitive Documents will constitute legal, valid and binding
obligations of Seller, enforceable against Seller in accordance with their
terms, upon the entry of the Sale Order (as defined in Section 6(c)(ii)(B));
provided, however, if Seller breaches this Agreement subsequent to approval of
this Agreement by the Bankruptcy Court and the entry of the Sale Order,
Buyer's damages are an administrative priority claim under Sections 503(b) and
507(a) of the Bankruptcy Code.

     (b)    No Conflict.  Except for (i) orders, approvals or authorizations
of the Bankruptcy Court and (ii) for consents, orders, approvals,
authorizations, or registrations, which, if not obtained, would not,
individually or in the aggregate, have a material adverse effect on the
Business, Seller has full power, right and authority to sell and transfer the
Acquired Assets to Buyer and the execution, delivery and performance of this
Agreement by Seller and compliance by Seller with the terms hereof will not
<PAGE>
(x) conflict with any provision of the organizational documents of Seller; (y)
result in a default (or give rise to any termination, cancellation or
acceleration) under any of the terms, conditions or provisions of any
agreement to which Seller is a party or by which it is bound, except for such
defaults (or rights of termination, cancellation or acceleration) as to
requisite waivers or consents have been obtained; or (z) violate any statute,
law, rule, regulation, order, writ, injunction or decree of any governmental
authority or create a lien, encumbrance, security interest or claim upon any

     (c)    Title.  Seller has, and at the Closing Buyer will obtain, good and
marketable title to the Acquired Assets, free and clear of all liens, claims,
interests, encumbrances and security interests of any kind or nature
whatsoever.  Seller has not licensed or otherwise granted any person or entity
any right or interest in any of the Acquired Assets.  No person or entity
currently maintains any claim, and, no person or entity has a valid basis for
claiming that the operation of the Business or the use of the Acquired Assets
infringes, violates or has violated any licensing agreement, patent, non-
competition, confidentiality or trademark right or copyright or other rights
of any other person or entity.

     (d)    Litigation.  Except as set forth on Schedule 4(d), there is no
claim, judgment, litigation or proceeding in existence or pending at present,
or to the knowledge of Seller threatened, against or relating to the Acquired
Assets or the Business which would affect or encumber the Acquired Assets; no
replevins, attachments, executions or tax assessments or liens are in force
against Seller or the Acquired Assets; and Seller does not know, or have
reasonable grounds to know, of any basis for any such action, or of any
governmental investigation relative to Seller, the Acquired Assets or the
Business.

     (e)    Customer Contracts.  Seller's right, title and interest in and to
each of the Customer  Contracts, is fully assignable and, on the Closing Date,
each such assumed Customer Contract will be in full force and effect and
Seller will not be in default thereunder.

     (f)    DSL Customers.  The DSL Customers consist of approximately 16,800
lines.

the transaction contemplated by this Agreement and no brokerage fees will be
payable by Seller to any party as the result of the consummation of such
transaction.

     (h)    Compliance With Law.  To Seller's knowledge, Seller has filed with
the appropriate governmental authorities all material applications,
notifications and other documents and has been issued and is in compliance
with all material requirements for all laws, regulations, permits,
certificates, licenses, approvals and other authorizations required to operate
the Business, except where the failure to do so would not have a material
adverse effect on the Business.  Seller is in material compliance with each
(and has not received any claim or notice that the Business is not in
compliance with or that it is in violation of any) law to which the Business
is subject (including all record keeping and reporting requirements thereof);
and, to the Seller's knowledge, no prior actions of the Seller in violation of
any law or regulation will result in liability to the Buyer as a result of the
transactions contemplated by this Agreement.

<PAGE>
<PAGE>
     (i)    Governmental Notices.  Seller has not received from any
governmental authority or third party any material request for information,
notice of claim, demand letter, or other notification in connection with the

and in good standing under the laws of the state of Delaware and has the power
and authority and all necessary governmental approvals to own, lease and
operate its properties and to carry on its business as it is now being
conducted.  Buyer is duly qualified to do business, and is in good standing,
in each jurisdiction where the character of its properties owned or held under
lease or the nature of its activities make such qualification appropriate,
except where the failure to be so qualified would not individually or in the
aggregate have a material adverse effect on Buyer's ability to complete the
transactions contemplated by this Agreement.  The execution and delivery of
this Agreement to Seller and the transactions contemplated hereby have been
duly authorized by Buyer's Board of Directors, and Buyer shall deliver to
Seller, at or prior to the execution hereof, copies, certified by Buyer's
Secretary, of the minutes of the meeting of its Board of Directors at which
such authority was granted.

     (b)    Buyer has taken all action required by the laws of the State of
Delaware or any other applicable law to authorize the transactions
contemplated herein.

     (c)    There are no pending or, to the knowledge of Buyer, threatened
actions or proceedings before any court or administrative agency or other
authority which might or will materially or adversely affect Buyer's ability
or right to perform all Buyer's obligations hereunder.

     (d)    This Agreement constitutes the legal, valid, and binding agreement
of Buyer, enforceable in accordance with its terms.  The consummation of the
transactions contemplated hereby will not conflict with or result in a breach
of any provision of, or constitute a default under, any contract, agreement,
instrument, regulation, law, or order of any court, administrative agency or
federal, state, or local authority to which Buyer is a party, by which it is
bound, or to which it may be subject for which Buyer has not obtained a waiver
or the consent of the affected party.  The execution, delivery, and
performance of this Agreement by Buyer will not (i) conflict with or result in
a breach or violation of any term or provision of Buyer's Certificate of
Incorporation or Bylaws, nor shall its execution, delivery, or performance
conflict with or result in a breach of any of the terms, conditions, or any
provision of, or constitute a default (or give rise to any right of
termination, cancellation, acceleration, vesting, payment exercise, suspension
or revocation) under, any indenture, mortgage, contract, agreement, or other
<PAGE>
instrument to which Buyer is a party, or by which it or its properties are or
may be bound or affected, (ii) violate any order, writ, injunction, decree,
statute, rule or regulation applicable to the Buyer or the Buyer's properties
or assets,  except for violations, breaches, defaults, terminations,
cancellations, accelerations, creations, impositions, suspensions or
revocations that would not individually or in the aggregate have a material
adverse effect on the Buyer's ability to complete the transactions
contemplated by this Agreement, or (iii) constitute an event that would permit
any party to terminate any agreement or accelerate the maturity of any
indebtedness or other obligation of Buyer.

     (e)    No broker has been engaged by Buyer in connection with the
transaction contemplated by this Agreement and no brokerage fees will be
payable by the Buyer to any party as the result of the consummation of such
transaction.

     (f)  Buyer has sufficient cash and/or available credit facilities and/or
commitments to pay the Purchase Price and the Covad Cure Amount and to make
all other necessary payments of fees and expenses in connection with the
transactions contemplated by this Agreement and the Definitive Documents.

6.    COVENANTS

     (a)    Access and Investigation.  Between the date hereof and the
Closing, Seller grants to Buyer and to its duly authorized representatives
including, but not limited to, its employees, accountants and counsel
reasonable access to (i) all information concerning the Acquired Assets and or
the Business as Buyer may reasonably request and (ii) reasonable access,
during normal business hours, to the Acquired Assets and to present and former
key management employees of the Business who have significant information
regarding the Acquired Assets and Business, and releases all such employees
from any obligations of confidentiality or non-disclosure with regard to
disclosures made by such employees to the Buyer for the purpose of evaluating
the transactions contemplated by this Agreement.

     (b)    Notice of Sale.  Seller will mail notice of the sale, which notice
will comply and be served in accordance with the Bankruptcy Code, the Federal
Rules of Bankruptcy Procedure, any applicable local bankruptcy rules, and any
applicable order of the Bankruptcy Court, to parties who assert any interest,
lien, encumbrance or claim in or against the Acquired Assets (including but
not limited to Nortel Networks, Inc.), in addition to the DSL Customers,
Covad, any nondebtor party to a contract that is being assigned hereunder, and
any committee of unsecured creditors appointed in the Chapter 11 Case.

     (c)    Bankruptcy Court Approvals.

            (i)    Seller confirms that its negotiation of this Agreement with
Buyer is critical to its obtaining the highest and best price for its assets,
and that without Buyer's commitment of substantial time and expense to the
process, Seller would have to employ a less orderly process for the sale of
its assets and therefore risk attracting lower prices.  Seller acknowledges
that Buyer would not have invested the time and incurred the expense of
negotiating and documenting the transaction if it were not entitled to a break
up fee as described below.  Notwithstanding anything in this Agreement to the
contrary, if Buyer is not the successful bidder for the Acquired Assets
because a bid or bids higher and better than the Purchase Price is approved by
the Bankruptcy Court, Buyer shall be entitled to a break-up fee of Forty
Thousand  and 00/00 United States Dollars (US $40,000.00) (the "Break-up
Fee"), provided this Agreement has not been terminated by Seller under Section
<PAGE>
11(a)(v) at that time.  The Break-Up fee shall be payable to Buyer at the
closing of the sale of the Acquired Assets to such alternate bidder.

          (ii)    As promptly as possible after the date hereof, Seller will
file and serve motions (and, at a minimum, notice will be made to Covad and
all DSL Customers and any other parties to Customer Contracts or any contracts
being assigned hereunder) pursuant to Bankruptcy Code Sections 105, 363, and
365, as applicable, in a form reasonably approved by counsel for Buyer:

                  (A)    seeking entry of an order (on an expedited basis)
substantially in the form attached hereto as Exhibit D (the "Procedures
Order"), approving among other things the payment of the Break-Up Fee as an
administrative priority claim under Bankruptcy Code Sections 503(b) and
507(a), approving procedures for the sale of the Acquired Assets (including an
overbid amount of US $100,000.00 over the Purchase Price, an incremental bid
amount of US $50,000.00 and matching bid provisions), and setting dates for
the auction sale of the Acquired Assets no later than November 16, 2001 (the
"Auction Hearing Date"), and the hearing on the sale of the Acquired Assets no
later than November 16, 2001 (the "Sale Hearing Date"); and

                  (B)    seeking entry of an order substantially in the form
attached hereto as Exhibit E (the "Sale Order"), which, among other things,
(i) authorizes Seller to sell, transfer and assign the Acquired Assets to
Buyer, on an expedited basis, pursuant to this Agreement and Bankruptcy Code
Sections 105, 363 and 365, as applicable, free and clear of liens, claims,
interests, encumbrances and security interests of any nature or kind, (ii)
determines that Buyer is a good faith purchaser under Section 363(m) of the
Bankruptcy Code and that the Buyer has acted in good faith, is a bona fide
purchaser for value, the Purchase Price is fair and reasonable, and the sale
of the Acquired Assets is free and clear of all liens, claims, interests, and
encumbrances; (iii) provides that the Customer Contracts and the Covad
Contract are assigned to Buyer pursuant to 11 U.S.C. Section 365, that Buyer
assumes no liability for claims or cure amounts under the Customer Contracts
prior to the date of Closing, that all Customer Contracts and the Covad
Contract are enforceable against the nondebtor parties and that Buyer assumes
the Covad Cure Amount pursuant to Section 6(i); (iv) Seller assumes any
obligation to cure the Customer Contracts; (v) provides that Section 1146(c)
applies to the sale; (vi) is in all respects in a form reasonably acceptable
to Counsel for Buyer; (vii) provides that the ten (10) day periods provided for
in Federal Rules of Bankruptcy Procedure 6004(g) and 6006(d) are waived;
and (viii) provides that the Parties shall hold the funds collected on account
of any accounts receivable that are owed to the other party in trust and that
commingling of such accounts receivable with the Parties' general funds
or accounts shall not destroy the trust protection or nature of such funds
or impact the duties each Party owes to the other with regard to accounts
receivable.

     (d)    Books and Records.  After the Closing, Buyer shall allow Seller
and any of its then current directors, officers, employees, counsel,
representatives, accountants and auditors (collectively, the "Seller's
Representatives") reasonable access to all business records and files of the
Seller or the Business that are transferred solely to Buyer in connection
herewith, which are reasonably required by such Seller's Representatives in
order to complete the Chapter 11 Case or for tax or other valid business
purposes, during regular business hours and upon reasonable notice to Buyer.
The Seller's Representatives shall have the right to make copies of any such
records and files; provided, however, that any such access or copying shall be
had or done in such a manner so as not to unreasonably interfere with the
normal conduct of Buyer's business or operations.

     (j)    December Billing.  Seller shall not send bills to the DSL
Customers for the month of December 2001.

7.    CONFIDENTIALITY

      (a)    The Seller possesses and will possess following the Closing
confidential and proprietary business information relating to the Acquired
Assets and the Business (the "Proprietary Information").  The Seller agrees
that it will maintain the confidentiality of all Proprietary Information and
will not use, or disclose to any other party, for any purpose whatsoever, any
Proprietary Information relating to the Acquired Assets or the Business.
Further Seller acknowledges the critical importance of maintaining the
<PAGE>
<PAGE>
Proprietary Information as confidential and agrees that because any award of
monetary damages would be inadequate for any breach of this covenant and would
cause prior irreparable harm to Buyer, that in any event of the breach or
threatened breach of this covenant Buyer will be entitled to equitable relief,
including injunctive relief and specific performance.  Such remedy shall not
be the exclusive remedy for any breach of this covenant but will be in
addition to all other remedies available at law or equity.

     (b)    The Buyer agrees that prior to the Closing and, in the event that
the Buyer is not the successful bidder, after the termination of this
Agreement, it will not disclose confidential information with respect to the
Seller, the Acquired Assets or the Business, for any purpose or reason
whatsoever (except to authorized representatives of the Buyer and to counsel
and other advisers, provided that such advisors (other than counsel) agree to
the confidentiality provisions of this Section 7(b)), unless (i) such
information becomes known to the public generally through no fault of the
Buyer, (ii) disclosure is required by law or the order of any governmental or
regulatory authority under color of law, or (iii) the Buyer reasonably
believes that such disclosure is required in connection with the defense of a
lawsuit or for certification or state licensure purposes; provided, that prior
to disclosing any information pursuant to clauses (ii) or (iii) above, the
Buyer shall, if possible, give prior written notice thereof to the Seller, its
successors or assigns, and provide the Seller, its successors or assigns with
the opportunity to contest such disclosure. Further Buyer acknowledges the
critical importance of maintaining the Proprietary Information as confidential
and agrees that because any award of monetary damages would be inadequate for
any breach of this covenant and would cause prior irreparable harm to Seller,
that in any event of the breach or threatened breach of this covenant Seller
will be entitled to equitable relief, including injunctive relief and specific
performance.  Such remedy shall not be the exclusive remedy for any breach of
this covenant but will be in addition to all other remedies available at law
or equity.

any press release or make any public announcement relating to the subject
matter of this Agreement without the prior written approval of the other
party; provided, however, that any party may make any public disclosure it
believes in good faith is required by applicable law as determined by a
written opinion of counsel or any listing or trading agreement concerning its
publicly-traded securities (in which case the disclosing party will use
commercially reasonable efforts to advise the other party prior to making the
disclosure).  In addition, the Parties shall jointly prepare a letter to be
sent to the DSL Customers subsequent to the Effective Date to explain Buyer's
purchase of the Acquired Assets and the transition of such contracts.
