                             ELASTIC NETWORKS INC.
                            ACCELERATED VESTING PLAN

     This Elastic Networks Inc. Accelerated Vesting Plan ("Plan") is hereby
effective as of the 26th day of May, 1999, by Elastic Networks Inc., a
Delaware corporation ("Company"), for the benefit of the eligible participants
described herein.

                                  WITNESSETH:

     WHEREAS, the Participants (as defined below) are currently employed by or
provide services to the Company (as defined below); and

     WHEREAS, the Company desires to establish the Plan to provide certain
benefits to such Participants in the event of a Change in Control (as defined
below).

     NOW, THEREFORE, the Company hereby establishes the Plan as set forth below.

1.   DEFINITIONS.

     For purposes of this Plan:

     (a)  "Affiliate" shall have the meaning set forth in Rule 12b-2 under the
          Securities Exchange Act of 1934, as amended.

     (b)  A "Change in Control" shall be deemed to take place on the occurrence
          of any of the following events after the adoption of the Plan:

          (1)  any merger or consolidation which results in the voting
               securities of the Company outstanding immediately prior thereto
               representing immediately thereafter (either by remaining
               outstanding or by being converted into voting securities of the
               surviving or acquiring entity) less than 50% of the combined
               voting power of the voting securities of the Company or such
               surviving or acquiring entity outstanding immediately after such
               merger or consolidation;

          (2)  any sale of all or substantially all of the assets of the
               Company; or

          (3)  the complete liquidation of the Company.

          Notwithstanding the foregoing, the election of any Purchaser (as
          defined in the Right of First Offer and Co-Sale Agreement, dated as
          of May 1999 and as amended from time to time, by and among the
          Company, Nortel Networks Inc. ("Nortel Networks") and the persons
          and entities listed on Exhibit A thereto (the "Right of First Offer
          Agreement")) to sell its Shares (as defined in the Right of First
          Offer Agreement) to Nortel Networks pursuant to Section 6 of the
          Right of First Offer Agreement, and the purchase of any such Shares
          by Nortel Networks, shall not be deemed to be a Change in Control.

     (c)  "Participant" shall mean (i) a common-law employee (whether or not an
          officer) of the Company who is compensated on a salaried basis or (ii)
          a service provider

<PAGE>

          or independent contractor who provides services to the Company, and in
          either case whom the Board of Directors of the Company selects to
          participate in and be covered under the Plan.

2.   ACCELERATED VESTING OF OPTIONS.

     If and only if a Change in Control occurs, all outstanding stock options
that the Company previously granted to the Participant before the Change in
Control shall be exercisable (to the extent not previously exercisable), in
whole or in part, with respect to an additional fifty percent (50%) of the
shares of stock to which the outstanding stock options are not at that time
exercisable as of the Change of Control and such stock options shall remain
exercisable to such extent thereafter in accordance with the terms of such
options and the applicable plans pursuant to which they were granted,
notwithstanding any provisions in the stock options or plans to the contrary
regarding the exercisability of such stock options.

3.   ADMINISTRATION OF THE PLAN.

     The Company shall interpret and administer the Plan. The Company shall
establish rules for the administration of the Plan. The Company shall have the
discretionary authority to construe the terms of the Plan and shall determine
all questions arising in its administration, interpretation and application,
including those concerning eligibility for benefits. All determinations of the
Company shall be final and binding on all Participants and beneficiaries. The
Company may appoint a committee or an agent or other representative to act on
its behalf and may delegate to such committee or agent or representative any of
its powers hereunder. Any action that such committee or agent or representative
takes shall be considered to be the action of the Company, when the committee or
agent or representative is acting within the scope of the authority that the
Company delegated to it, and the Company shall be responsible for all such
actions.

4.   APPLICABLE LAW.

     This Plan shall be construed and interpreted pursuant to the laws of the
State of Delaware.

5.   NO EMPLOYMENT CONTRACT.

     Nothing contained in this Plan shall be construed to be an employment
contract between a Participant and the Company.

6.   SEVERABILITY.

     In the event any provision of this Plan is held illegal or invalid, the
remaining provisions of this Plan shall not be affected thereby.

7.   SUCCESSORS.

     The Plan shall be binding upon and inure to the benefit of the Company, the
Participants and their respective heirs, representatives and successors.

                                       2

8.   AMENDMENT AND TERMINATION.

     The Company shall have the right to amend the Plan from time to time and
may terminate the Plan at any time; provided that after a Change in Control
occurs (i) no amendment may be made that diminishes any Participant's rights
following such Change in Control and (ii) the Plan may not be terminated.

9.   NOTICE.

     Notices under this Plan shall be in writing and sent by registered mail,
return receipt requested, to the following addresses or to such other address as
the party being notified may have previously furnished to the other party by
written notice:

     If to the Company:

             Elastic Networks Inc.
             6120 Windward Parkway
             Suite 100
             Alpharetta, Georgia  30005
             Attention: Mr. Kevin D. Elop

     If to a Participant:

             The address last indicated on the records of the Company.

10.  EXCISE TAXES.

     Despite any other provisions of this Plan to the contrary, if by reason of
accelerated vesting under this Plan a Participant becomes subject to a tax
liability under Code Section 4999, the Company may determine whether some amount
of the accelerated vesting would meet the definition of a "Reduced Amount." If
the Company determines that there is a Reduced Amount, the total payments to the
Participant hereunder must be reduced to such Reduced Amount, but not below
zero. If the Company determines that the payments must be reduced to the Reduced
Amount, the Company must promptly notify the Participant of that determination,
with a copy of the detailed calculations by the Company. All determinations of
the Company under this Section 10 are binding upon the Participant. It is the
intention of the Company and the Participant to reduce the payments under this
Plan only if the aggregate Net After Tax Receipts to the Participant would
thereby be increased. If as result of the uncertainty in the application of Code
Section 4999 at the time of the initial determination by the Company under this
Section 10, however, it is possible that amounts will have been paid under the
Plan to or for the benefit of a Participant which should not have been so paid
("Overpayment") or that additional amounts which will not have been paid under
the Plan to or for the benefit of a Participant could have been so paid
("Underpayment") - in each case, consistent with the calculation of the Reduced
Amount. If the Company, based either upon the assertion of a deficiency by the
Internal Revenue Service against the Company or the Participant which the
Company believes has a high probability of success or controlling precedent or
other substantial authority, determines that an Overpayment has been made, any
such Overpayment must be treated for all purposes as a loan which the
Participant must repay to the Company together with interest at the applicable
federal rate under Code Section 7872(f)(2); provided, however, that no such loan
may be deemed to have been made and no amount shall be payable by Participant to
the Company if and to the extent such deemed loan and payment would not either
reduce the amount on which the Participant is subject to tax under Code Section
1, 3101 or 4999 or generate a refund of such taxes. If the

                                       3
<PAGE>

Company, based upon controlling precedent or other substantial authority,
determines that an Underpayment has occurred, the Company must promptly notify
the Participant of the amount of the Underpayment, which then shall be paid to
the Participant. For purposes of this section, (i) "Net After Tax Receipt" means
the Present Value of a payment under this Plan net of all taxes imposed on
Participant with respect thereto under Code Sections 1, 3101 and 4999,
determined by applying the highest marginal rate under Code section 1 which
applied to the Participant's taxable income for the immediately preceding
taxable year; (ii) "Present Value" means the value determined in accordance with
Code Section 280G(d)(4); and (iii) "Reduced Amount" means the smallest aggregate
amount of all payments under this Plan which (a) is less than the sum of all
payments under this Plan and (b) results in aggregate Net After Tax Receipts
which are equal to or greater than the Net After Tax Receipts which would result
if the aggregate payments under this Plan were any other amount less than the
sum of all payments to be made under this Plan.

11.  MISCELLANEOUS.

     (a)  The failure of the Company to enforce any provisions of the Plan shall
          in no way be construed to be a waiver of those provisions, nor in any
          way effect the validity of the Plan or any part thereof, or the right
          of the Company thereafter to enforce such provision.

     (b)  The benefits provided under this Plan are in addition to and not in
          lieu of any other similar benefits that the Company or any Affiliate
          may specify from time to time in any employee handbook or in any other
          agreement between the Participant and the Company. Additionally, the
          benefits that this Plan provides shall not be reduced or offset by any
          other payments or benefits that the Participant may receive from any
          other third party or other employer after the termination of the
          Participant's employment with the Company or any Affiliate.

     IN WITNESS WHEREOF, the Company has caused this instrument to be executed
in its name by its duly authorized officer, all as of the day and year first
above written.

     letter of credit in lieu of cash) with instructions to the Trustee
     to purchase one or more of such Securities which cash (or cash in an
     amount equal to the face amount of the letter of credit), to the
     extent not used by the Trustee to purchase such Securities within the
     90-day period following the first deposit of Securities in the Trust,
     shall be distributed to Unit Holders on the Distribution Date next
     following such 90-day period or such earlier date as the Depositor
     and the Trustee determine".

                                  - 2 -

         B.  Section 2.03 is amended to add the following to the end of
     the first paragraph thereof. The number of Units may be increased
     through a split of the Units or decreased through a reverse split
     thereof, as directed by the Depositor, which revised number of Units
     shall be recorded by Trustee on its books.

         C.  The first sentence of Section 2.06 is amended to add the
     following language after "Securities": "and/or cash (or a letter
     of credit in lieu of cash) with instructions to the Trustee to purchase
     one or more Additional Securities which cash (or cash in an amount
     equal to the face amount of the letter of credit), to the extent not
     used by the Trustee to purchase such Additional Securities within the
     90-day period following the first deposit of Securities in the Trust,
     shall be distributed to Unit Holders on the Distribution Date next
     following such 90-day period or such earlier date as the Depositor
     and the Trustee determine".

         D.  Article III, entitled "Administration of Trust", Section
     3.01 Initial Cost shall be amended as follows:

          Section 3.01 Initial Cost shall be amended to substitute the
following language:

          SECTION 3.01. INITIAL COST The costs of organizing the Trust
     and sale of the Trust Units shall, to the extent of the expenses
     reimbursable to the Depositor provided below, be borne by the Unit
     Holders, provided, however, that, to the extent all of such costs are
     not borne by Unit Holders, the amount of such costs not borne by Unit
     Holders shall be borne by the Depositor and, PROVIDED FURTHER, however,
     that the liability on the part of the Depositor under this section
     shall not include any fees or other expenses incurred in connection
     with the administration of the Trust subsequent to the deposit referred
     to in Section 2.01. Upon notification from the Depositor that the
     primary offering period is concluded, the Trustee shall withdraw from
     the Account or Accounts specified in the Prospectus or, if no Account
     is therein specified, from the Principal Account, and pay to the
     Depositor the Depositor's reimbursable expenses of organizing the Trust
     and sale of the Trust Units in an amount certified to the Trustee by
     the Depositor. If the balance of the Principal Account is insufficient
     to make such withdrawal, the Trustee shall, as di-

<PAGE>

                                  - 3 -

     rected by the Depositor, sell Securities identified by the Depositor, or
     distribute to the Depositor Securities having a value, as determined
     under Section 4.01 as of the date of distribution, sufficient for such
     reimbursement. The reimbursement provided for in this section shall be
     for the account of the Unitholders of record at the conclusion of the
     primary offering period and shall not be reflected in the computation of
     the Unit Value prior thereto. As used herein, the Depositor's reimbursable
     expenses of organizing the Trust and sale of the Trust Units shall include
     the cost of the initial preparation and typesetting of the registration
     statement, prospectuses (including preliminary prospectuses), the
     indenture, and other documents relating to the Trust, SEC and state
     blue sky registration fees, the cost of the initial valuation of the
     portfolio and audit of the Trust, the initial fees and expenses of the
     Trustee, and legal and other out-of-pocket expenses related thereto,
     but not including the expenses incurred in the printing of preliminary
     prospectuses and prospectuses, expenses incurred in the preparation and
     printing of brochures and other advertising materials and any other
     selling expenses. Any cash which the Depositor has identified as to be
     used for reimbursement of expenses pursuant to this Section shall be
     reserved by the Trustee for such purpose and shall not be subject to
     distribution or, unless the Depositor otherwise directs, used for
     payment of redemptions in excess of the per-Unit amount allocable to
     Units tendered for redemption.

         E.  The third paragraph of Section 3.05 is hereby amended to add the
     following sentence after the first sentence thereof: "Depositor may
     direct the Trustee to invest the proceeds of any sale of Securities
     not required for the redemption of Units in eligible money market
     instruments selected by the Depositor which will include only negotiable
     certificates of deposit or time deposits of domestic banks which are
     members of the Federal Deposit Insurance Corporation and which have,
     together with their branches or subsidiaries, more than $2 billion in
     total assets, except that certificates of deposit or time deposits of
     smaller domestic banks may be held provided the deposit does not exceed
     the insurance coverage on the instrument (which currently is $100,000),
     and provided further that the Trust's aggregate holding of certificates
     of deposit or time deposits issued by the Trustee may not ex-

<PAGE>

                                  - 4 -

     ceed the insurance coverage of such obligations and U.S. Treasury notes
     or bills (which shall be held until the maturity thereof) each of which
     matures prior to the  earlier of the next following Distribution Date or
     90 days after receipt, the principal thereof and interest thereon (to the
     extent such interest is not used to pay Trust expenses) to be distributed
     on the earlier of the 90th day after receipt or the next following
     Distribution Date."

         F.  The first sentence of each of Sections 3.10, 3.11 and 3.12 is
     amended to insert the following language at the beginning of such
     sentence, "Except as otherwise provided in Section 3.13,".

         G.  The following new Section 3.13 is added

         Section 3.13. EXTRAORDINARY EVENT-SECURITY RETENTION AND VOTING.
     In the event the Trustee is notified of any action to be taken or
     proposed to be taken by holders of the securities held by the Trust
     in connection with any proposed merger, reorganization, spin-off,
     split-off or split-up by the issuer of stock or securities held in the
     Trust, the Trustee shall take such action or refrain from taking any
     action, as appropriate, so as to insure that the securities are voted
     as closely as possible in the same manner and in the same general
     proportion as are the securities held by owners other than the Trust.
     If stock or securities are received by the Trustee, with or without
     cash, as a result of any merger, reorganization, spin-off, split-off or
     split-up by the issuer of stock or securities held in the Trust, the
     Trustee at the direction of the Depositor may retain such stock or
     securities in the Trust. Neither the Depositor nor the Trustee shall be
     liable to any person for any action or failure to take action with
     respect to this section.

         H.  Section 1.01 is amended to add the following definition:
     (9) "Deferred Sales Charge" shall mean any deferred sales charge
     payable in accordance with the provisions of Section 3.14 hereof, as
     set forth in the prospectus for a Trust. Definitions following this
     definition (9) shall be renumbered.

         I.  Section 3.05 is hereby amended to add the following paragraph
     after the end thereof: On each Deferred Sales Charge payment date set
     forth in the prospectus for

<PAGE>

                                  - 5 -

     a Trust, the Trustee shall pay the account created pursuant to
     Section 3.14 the amount of the Deferred Sales Charge payable on each
     such date as stated in the prospectus for a Trust. Such amount shall
     be withdrawn from the Principal Account from the amounts therein
     designated for such purpose.

         J.  Section 3.06B(3) shall be amended by adding the following:
     "and any Deferred Sales Charge paid".

         K.  Section 3.08 shall be amended by adding the following at the end
     thereof: "In order to pay the Deferred Sales Charge, the Trustee shall
     sell or liquidate an amount of Securities at such time and from time to
     time and in such manner as the Depositor shall direct such that the
     proceeds of such sale or liquidation shall equal the amount required to
     be paid to the Depositor pursuant to the Deferred Sales Charge program
     as set forth in the prospectus for a Trust.

         L.  Section 3.14 shall be added as follows:

     Section 3.14. Deferred Sales Charge. If the prospectus for a
     Trust specifies a Deferred Sales Charge, the Trustee shall, on the
     dates specified in and as permitted by the prospectus, withdraw from
     the Income Account if such account is designated in the prospectus as
     the source of the payments of the Deferred Sales Charge, or to the
     extent funds are not available in that account or if such account is
     not so designated, from the Principal Account, an amount per Unit
     specified in the prospectus and credit such amount to a special,
     non-Trust account maintained at the Trustee out of which the Deferred
     Sales Charge will be distributed to the Depositor. If the Income
     Account is not designated as the source of the Deferred Sales Charge
     payment or if the balances in the Income and Principal Accounts are
     insufficient to make any such withdrawal, the Trustee shall, as
     directed by the Depositor, either advance funds, if so agreed to by the
     Trustee, in an amount equal to the proposed withdrawal and be entitled
     to reimbursement of such advance upon the deposit of additional monies
     in the Income Account or the Principal Account, sell Securities and
     credit the proceeds thereof to such special Depositor's account or
     credit Securities in kind to such special Depositor's Account. Such
     directions shall identify the Securities, if any, to be

<PAGE>

                                  - 6 -

     sold or distributed in kind and shall contain, if the Trustee is
     directed by the Depositor to sell a Security, instructions as to
     execution of such sales. If a Unit Holder redeems Units prior to full
     payment of the Deferred Sales Charge, the Trustee shall, if so provided
     in the prospectus, on the Redemption Date, withhold from the Redemption
     Price payment to such Unit Holder an amount equal to the unpaid portion
     of the Deferred Sales Charge and distribute such amount to such special
     Depositor's account or, if the Depositor shall purchase such Unit
     pursuant to the terms of Section 5.02 hereof, the Depositor shall pay
     the Redemption Price for such Unit less the unpaid portion of the
     Deferred Sales Charge. The Depositor may at any time instruct the
     Trustee to distribute to the Depositor cash or Securities previously
     credited to the special Depositor's account.

         M.  Reference to "Dean Witter Select Equity Trust" is replaced by
     "Morgan Stanley Dean Witter Select Equity Trust".
