                         REGISTRATION RIGHTS AGREEMENT

         REGISTRATION RIGHTS AGREEMENT, dated as of August 3, 2001 (this
"Agreement"), by and between NORTEL NETWORKS LLC, a limited liability company
organized under the laws of Delaware ("Investor") and ARRIS GROUP, INC. f/k/a
Broadband Parent Corporation, a Delaware corporation ("Newco").

         WHEREAS, pursuant to (i) an Agreement and Plan of Reorganization dated
as of October 18, 2000, as amended (the "Plan of Reorganization") among Newco,
ANTEC Corporation, Broadband Transition Corporation, Nortel Networks Inc.,
Investor and Arris Interactive L.L.C., and (ii) an Amended and Restated
Investor Rights Agreement dated as of April 9, 2001, as amended, among Newco,
Nortel Networks Inc. and Investor, Investor will receive at the Closing (as
such term is defined in the Plan of Reorganization) shares of Newco Common
Stock (such shares and any shares of Newco Common Stock acquired or to be
acquired from time to time by Investor and any Permitted Transferee (as defined
below), the "Newco Shares");

         WHEREAS, in connection with the Plan of Reorganization, Newco has
agreed to provide Investor certain registration rights as provided herein.

         NOW, THEREFORE, in consideration of the premises and of the mutual
covenants herein contained, the parties hereto agree as follows:

         1.       Demand Registration.

                  (a)      Investor or any person acquiring by transfer any
         Newco Shares (a "Permitted Transferee") (Investor and any such
         Permitted Transferees being hereinafter referred to individually as a
         "Stockholder" and collectively as the "Stockholders") shall at any
         time have the right to require registration under the Securities Act
         (as defined below), of the Newco Shares and any securities issued in
         exchange for or in respect of such Newco Shares, whether pursuant to a
         stock dividend, stock split, stock reclassification, recapitalization
         or otherwise (such Newco Shares and such securities issued in exchange
         for or in respect of such Newco Shares being collectively referred to
         herein as the "Registrable Shares") upon the terms and subject to the
         conditions set forth in this Agreement. For purposes of this
         Agreement, "Securities Act" shall mean the United States Securities
         Act of 1933, as amended, or any successor federal statute, and the
         rules and regulations of the United States Securities and Exchange
         Commission (or any other federal agency at the time administering such
         Act) (the "Commission") issued under such Act, as they may, from time
         to time, be in effect.

                  (b)      Upon receipt by Newco of a written demand for
         registration hereunder, Newco shall (i) promptly notify each other
         Stockholder in writing of its receipt of such

<PAGE>   2

         initial written demand for registration and (ii) as soon as
         practicable, but in no event more than 30 days (except that with
         respect to any registration on a Form S-1 Registration Statement (or
         successor form thereto), such period shall be 45 days) after receipt
         of such written demand, file with the Commission, and use its
         reasonable best efforts to cause to become effective, a registration
         statement under the Securities Act (a "Registration Statement") which
         shall cover the Registrable Shares specified in the initial written
         demand and in any written demand from any other Stockholder received
         by Newco within 20 days of its giving the notice specified in clause
         (i) hereof.

                  (c)      If so requested by any Stockholder demanding
         participation in a public offering or distribution of Registrable
         Shares (a "Selling Stockholder") pursuant to this Section 1, the
         Registration Statement shall provide for a delayed or continuous
         offering of Registrable Shares pursuant to Rule 415 promulgated under
         the Securities Act or any similar rule then in effect (a "Shelf
         Offering"). If so requested by Selling Stockholders who own a majority
         of the Registrable Shares then outstanding, the public offering or
         distribution of Registrable Shares under this Agreement shall be
         pursuant to a firm commitment underwriting, the managing underwriter
         of which shall be a nationally recognized investment banking firm
         selected by the Selling Stockholders and approved by Newco, which
         approval shall not be unreasonably withheld. Newco shall enter into
         the same underwriting agreement as shall the Selling Stockholders,
         containing representations, warranties and agreements customarily made
         by an issuer in underwriting agreements with respect to secondary
         distributions. Newco, as a condition to fulfilling its obligations
         under this Agreement, may require the underwriters to enter into an
         agreement in customary form indemnifying Newco and the Selling
         Stockholders against any Losses (as defined in Section 6 hereof) that
         arise out of or are based upon an untrue statement or an alleged
         untrue statement or omission in the Disclosure Documents (as defined
         in Section 6 hereof) made in reliance upon and in conformity with
         written information furnished to Newco by the underwriters
         specifically for use in the preparation thereof.

                  (d)      If the Board of Directors of Newco, in its good
         faith judgment, determines that the filing of a Registration Statement
         pursuant to this Section 1 should not be made because it would
         materially and adversely affect any material business transaction
         involving Newco (a "Valid Business Reason"), Newco may postpone filing
         such a Registration Statement until such Valid Business Reason no
         longer exists, but in no event for more than 75 days (such period of
         postponement, the "Postponement Period"); and Newco shall give written
         notice of its determination to postpone the filing of a Registration
         Statement and of the fact that the Valid Business Reason for such
         postponement no longer exists, in each case, promptly after the
         occurrence thereof; provided, however, Newco shall not be permitted to
         postpone the filing of a Registration Statement after the expiration
         of any Postponement Period until 12 months after the expiration of
         such Postponement Period. If Newco shall give any notice of
         postponement of any Registration Statement, Newco shall not, during
         the Postponement Period, register any shares of Newco Common Stock,
         other than pursuant to a registration statement on Form S-4 or S-8 (or
         an equivalent registration form then in effect). If Newco shall give

                                       2
<PAGE>   3

         any notice of postponement of the filing of a Registration Statement,
         Newco shall, at such time as the Valid Business Reason that caused
         such postponement no longer exists (but in no event later than 75 days
         after the date of the postponement), use its reasonable best efforts
         to effect the registration under the Securities Act of the Registrable
         Shares covered by the postponed Registration Statement in accordance
         with this Section 1. If Newco shall postpone the filing of any
         Registration Statement, any of the Selling Stockholders shall have the
         right to withdraw his or its demand for such registration by giving
         notice to Newco within 20 days of the notice of postponement. In the
         event that all of the Selling Stockholders withdraw their demand, such
         demand shall not be counted for purposes of determining the number of
         registrations to which Stockholders are entitled hereunder.

                  (e)      Each Selling Stockholder may, before such a
         Registration Statement becomes effective, withdraw his or its
         Registrable Shares from sale, should the terms of the sale not be
         satisfactory to such Selling Stockholder; should all Selling
         Stockholders who are participating in such registration so withdraw,
         however, such registration shall be deemed to have been effected for
         the purposes of Sections 4(a) and 4(c) hereof unless such Selling
         Stockholders pay (pro rata, in proportion to the number of shares
         requested to be included) within 20 days after any such withdrawal,
         all of the out-of-pocket expenses of Newco incurred in connection with
         such registration.

                  (f)      In the event that a Registration Statement demanded
         by a Selling Stockholder pursuant to Section 1 hereof involves a firm
         commitment underwritten public offering and the managing underwriter
         thereof determines reasonably and in good faith that the inclusion in
         such Registration Statement of any additional shares of Newco Common
         Stock or other securities of Newco to be offered and sold for the
         account of any person (including Newco) other than such Selling
         Stockholder (each, a "Piggy-Back Seller") would adversely affect the
         offering of any Registrable Shares by the Selling Stockholder, then,
         subject to the provisions of that certain Registration Rights
         Agreement, dated October 29, 1996, as amended, between ANTEC
         Corporation and Tele-Communications, Inc., as in effect on the date
         hereof (the "TCI Registration Rights Agreement"), the number of shares
         to be offered for the accounts of each Piggy-Back Seller shall be
         reduced or limited in proportion to the number of shares owned by each
         such Piggy-Back Seller (as compared to all such Piggy-Back Sellers) to
         the extent necessary to reduce the total number of shares to be
         included in such Registration Statement by all Piggy-Back Sellers to
         the amount that such managing underwriter determines would not
         adversely affect the offering of the number of Registrable Shares
         demanded to be registered by the Selling Stockholder. Subject to the
         provisions of the TCI Registration Rights Agreement, in no event shall
         a Selling Stockholder be required to reduce the number of Registrable
         Shares demanded to be registered by such Selling Stockholder pursuant
         to Section 1 hereof as a result of the inclusion in any Registration
         Statement of Newco Common Stock or other securities of Newco to be
         offered and sold for the account of any Piggy-Back Seller. All
         references in this Agreement to the TCI Registration Rights Agreement
         shall be understood to include the rights, remedies, obligations or
         liabilities of Newco (as successor to ANTEC Corporation) under the TCI
         Registration Rights Agreement upon

                                       3

         and by reason of the closing of the transactions contemplated by the
         Plan of Reorganization.

         2.       Incidental Registrations. Each time that Newco proposes to
register any of its equity securities under the Securities Act (other than a
registration effected solely to implement an employee benefit or stock option
plan or to sell shares obtained under any employee benefit or stock option plan
or a registration in connection with a transaction to which Rule 145 or any
successor rule of the Commission under the Securities Act is applicable),
whether for its account or the account of other stockholders of Newco, Newco
will give written notice to the Stockholders of its intention to do so. Each of
the Stockholders may give Newco a written request to register all or some of
its Registrable Shares in the registration described in the written notice from
Newco as set forth in the foregoing sentence, provided that such written
request is given within 20 days after receipt of any such notice from Newco
(with such request stating (i) the amount of Registrable Shares to be disposed
of and the intended method of disposition of such Registrable Shares and (ii)
any other information customarily requested by issuers in secondary
distributions to properly effect the registration of such Registrable Shares).
Upon receipt of such request, Newco will use its reasonable best efforts to
cause promptly all such Registrable Shares intended to be disposed of to be
registered under the Securities Act so as to permit their sale or other
disposition (in accordance with the intended methods set forth in the request
for registration), unless the sale is a firm commitment underwritten public
offering and the managing underwriter thereof determines reasonably and in good
faith in writing that the inclusion of such securities would materially
adversely affect the offering, in which case the number of shares to be offered
for the accounts of the Selling Stockholders shall be reduced or limited in
proportion to the number of shares owned by such Selling Stockholders to the
extent necessary to reduce the total number of shares to be included in such
offering to the amount recommended by such managing underwriting; provided,
that, subject to the provisions of the TCI Registration Rights Agreement, if
securities are being offered for the account of other persons or entities as
well as Newco, such reduction shall be made pro rata from the securities
intended to be offered by such persons and from the Selling Stockholders.

         Newco's obligations under this Section 2 shall apply to a registration
to be effected for securities to be sold for the account of Newco as well as a
registration statement which includes securities to be offered for the account
of other holders of Newco equity securities. No registration effected under
this Section 2 shall relieve Newco of its obligations to effect demand
registrations under Section 1.

         3.       Expenses of Registration. Newco shall pay all costs and
expenses directly attributable to the registration of the Registrable Shares
pursuant hereto, including, without limitation: (a) Commission, Nasdaq National
Market (or exchange) and NASD registration and filing fees; (b) fees and
expenses of compliance with state and provincial securities or "blue sky" laws
and in connection with the preparation of a "blue sky" survey, including
without limitation, reasonable fees and expenses of blue sky counsel; (c)
printing and copying expenses; (d)messenger and delivery expenses; (e) expenses
incurred in connection with any road show; (f) fees and disbursements of
counsel for Newco; (g) with respect to each registration, the fees and
disbursements of one counsel for the Selling Stockholders (selected by the
Selling Stockholders);

                                       4
<PAGE>   5

(h) fees and disbursements of all independent public accountants (including the
expenses of any audit and/or "cold comfort" letter) and fees and expenses of
other persons, including special experts, retained by Newco; (i) fees and
expenses of underwriters, if any, customarily paid by issuers or sellers of
securities. Notwithstanding the foregoing, all transfer taxes, brokerage
commissions and underwriters' discounts attributable to the Registrable Shares
being offered and sold by such Selling Stockholders and any out-of-pocket
expenses of the Selling Stockholders (except as expressly contemplated by the
preceding sentence) shall be for the account of the Selling Stockholders.

         4.       Limitations on Registration Rights. Notwithstanding anything
to the contrary contained elsewhere herein, the registration rights granted to
the Stockholders under the provisions of Section 1 hereof are expressly subject
to the following terms, conditions and limitations:

                  (a)      In no event shall Newco be obligated to effect more
         than three (3) registrations on a Form S-1 Registration Statement.

                  (b)      Newco shall not be required to effect any
         registration pursuant to Section 1 unless the demand or demands for
         registration cover an aggregate number of Registrable Shares
         constituting at least five percent (5%) of the then outstanding shares
         of Common Stock.

                  (c)      The Stockholders shall not be entitled to demand
         Newco to register Registrable Shares pursuant to Section 1 more than
         once in any 90-day period.

                  (d)      Newco shall be entitled to extend the time period
         specified in Section 1(b)(ii) with respect to the filing of a
         Registration Statement for an additional period of time not to exceed
         thirty (30) days if Newco, in order to comply with such demand, would
         be required to (A) undergo a special interim audit or (B) prepare and
         file with the Commission, sooner than would otherwise be required, pro
         forma or other financial statements relating to any proposed or
         probable transaction.

         5.       Obligations with Respect to Registration.

                  (a)      If and whenever Newco is obligated by the provisions
         of this Agreement to effect the registration of any Registrable Shares
         under the Securities Act, Newco shall, as expeditiously as possible:

                           (i)      prepare and file with the Commission a
                  Registration Statement on an appropriate registration form of
                  the Commission for the disposition of such Registrable Shares
                  in accordance with the intended method of disposition
                  thereof, and such Registration Statement shall comply as to
                  form in all material respects with the requirements of the
                  applicable form and include all financial statements required
                  by the Commission to be filed therewith, and Newco shall use
                  its

                                       5
<PAGE>   6

                  reasonable best efforts to cause such Registration Statement
                  to become and remain effective (provided, however, that
                  before filing a Registration Statement or prospectus or any
                  amendments or supplements thereto, or comparable statements
                  under securities or blue sky laws of any jurisdiction, Newco
                  will furnish to one counsel for the Selling Stockholders
                  participating in the planned offering and the underwriters,
                  if any, copies of all such documents proposed to be filed
                  (including all exhibits thereto), which documents will be
                  subject to the reasonable review and reasonable comment of
                  such counsel, and Newco shall not file any Registration
                  Statement or amendment thereto or any prospectus or
                  supplement thereto to which the holders of a majority of the
                  Registrable Shares covered by such Registration Statement or
                  the underwriters, if any, shall reasonably object in
                  writing);

                           (ii)     prepare and file with the Commission any
                  amendments and supplements to the Registration Statement and
                  to the prospectus used in connection therewith as may be
                  necessary to keep the Registration Statement effective and to
                  comply with the provisions of the Securities Act with respect
                  to the disposition of all Registrable Shares covered by the
                  Registration Statement for the period required to effect the
                  distribution of such Registrable Shares, but in no event
                  shall Newco be required to do so for a period of more than
                  180 days following the effective date of the Registration
                  Statement other than a Shelf Offering and for a Shelf
                  Offering, the earlier of (A) the date the offering is
                  completed and (B) two years following the effective date of
                  the Shelf Offering;

                           (iii)    furnish at Newco's expense to the Selling
                  Stockholders such number of copies of the Registration
                  Statement and any preliminary, final, supplemental or amended
                  prospectus, in conformity with the requirements of the
                  Securities Act, as may reasonably be requested by the Selling
                  Stockholders in order to facilitate the disposition of the
                  Registrable Shares covered by such Registration Statement,
                  but only while Newco is required under the provisions hereof
                  to cause a Registration Statement to remain effective;

                           (iv)     register or qualify the Registrable Shares
                  covered by a Registration Statement under such other
                  securities or blue sky laws of such jurisdictions in the
                  United States and Canada as the Selling Stockholders shall
                  reasonably request, and do any and all other acts and things
                  which may be necessary to enable each Selling Stockholder
                  whose Registrable Shares are covered by such Registration
                  Statement to consummate the disposition in such jurisdictions
                  of such Registrable Shares; provided, however, that Newco
                  shall in no event be required to qualify to do business as a
                  foreign corporation or a dealer in any jurisdiction where it
                  is not so qualified, to conform the composition of its assets
                  at the time to the securities and blue sky laws of such
                  jurisdiction, to exercise or file any general consent to
                  service of process in suits other than those arising out of
                  the offer and sale of the Registrable Shares covered by the
                  Registration Statement, or to subject itself to taxation, in
                  each case in any jurisdiction where it has not theretofore
                  done so;

                                       6
<PAGE>   7

                           (v)      promptly notify each Selling Stockholder
                  covered by such Registration Statement and each managing
                  underwriter, if any: (A) when the Registration Statement, any
                  pre-effective amendment, the prospectus or any prospectus
                  supplement related thereto or post-effective amendment to the
                  Registration Statement has been filed and, with respect to
                  the Registration Statement or any post-effective amendment,
                  when the same has become effective; (B) of any request by the
                  Commission or state or provincial securities authority for
                  amendments or supplements to the Registration Statement or
                  the prospectus related thereto or for additional information;
                  (C) of the issuance by the Commission of any stop order
                  suspending the effectiveness of the Registration Statement or
                  the initiation of any proceedings for that purpose; (D) of
                  the receipt by Newco of any notification with respect to the
                  suspension of the qualification of any Registrable Shares for
                  sale under the securities or blue sky laws of any
                  jurisdiction or the initiation of any proceeding for such
                  purpose; (E) of the existence of any fact of which Newco
                  becomes aware which results in the Registration Statement,
                  the prospectus related thereto or any document incorporated
                  therein by reference containing an untrue statement of a
                  material fact or omitting to state a material fact required
                  to be stated therein or necessary to make any statement
                  therein not misleading; and (F) if at any time the
                  representations and warranties contemplated by any
                  underwriting agreement, securities sale agreement, or other
                  similar agreement, relating to the offering shall cease to be
                  true and correct in all material respects; and, if the
                  notification relates to an event described in clause (E),
                  Newco shall promptly prepare and furnish to each such Selling
                  Stockholder and each underwriter, if any, a reasonable number
                  of copies of a prospectus supplemented or amended so that, as
                  thereafter delivered to the purchasers of such Registrable
                  Shares, such prospectus shall not include an untrue statement
                  of a material fact or omit to state a material fact required
                  to be stated therein or necessary to make the statements
                  therein, in the light of the circumstances under which they
                  were made, not misleading;

                           (vi)     comply with all applicable rules and
                  regulations of the Commission, and make generally available
                  to its security holders, as soon as reasonably practicable
                  after the effective date of the Registration Statement (and
                  in any event within 16 months thereafter), an earnings
                  statement (which need not be audited) covering the period of
                  at least twelve consecutive months beginning with the first
                  day of Newco's first calendar quarter after the effective
                  date of the Registration Statement, which earnings statement
                  shall satisfy the provisions of Section 11(a) of the
                  Securities Act and Rule 158 (or any successor rule)
                  thereunder;

                           (vii)    enter into such customary agreements
                  (including, if applicable, an underwriting agreement) and
                  take such other actions as the holders of a majority of the
                  Registrable Shares participating in such offering shall
                  reasonably request in order to expedite or facilitate the
                  disposition of such Registrable Shares. The holders of the
                  Registrable Shares which are to be distributed by such
                  underwriters

                                       7

                  shall be parties to such underwriting agreement and may, at
                  their option, require that Newco make to and for the benefit
                  of such Selling Stockholders the representations, warranties
                  and covenants of Newco which are being made to and for the
                  benefit of such underwriters;

                           (viii)   obtain an opinion from Newco's counsel and
                  a "cold comfort" letter from Newco's independent public
                  accountants in customary form and covering such matters as
                  are customarily covered by such opinions and "cold comfort"
                  letters delivered to underwriters in underwritten public
                  offerings, which opinion and letter shall be reasonably
                  satisfactory to the underwriter, if any, and to the Selling
                  Stockholders, and furnish to each Selling Stockholder and to
                  each underwriter, if any, a copy of such opinion and letter
                  addressed to such Selling Stockholder or underwriter;

                           (ix)     deliver promptly to each Selling
                  Stockholder and each underwriter, if any, copies of all
                  correspondence between the Commission and Newco, its counsel
                  or auditors, make reasonably available for inspection by any
                  Selling Stockholder of such Registrable Shares covered by
                  such Registration Statement, by any underwriter participating
                  in any disposition to be effected pursuant to such
                  Registration Statement and by any attorney, accountant or
                  other agent retained by any such Selling Stockholder or any
                  such underwriter, all pertinent financial and other records,
                  pertinent corporate documents and properties of Newco, and
                  cause all of Newco's officers, directors and employees to
                  supply all information reasonably requested by any such
                  Selling Stockholder, underwriter, attorney, accountant or
                  agent in connection with such Registration Statement;

                           (x)      use its reasonable best efforts to obtain
                  the withdrawal of any order suspending the effectiveness of
                  the Registration Statement;

                           (xi)     promptly prior to the filing of any
                  document which is to be incorporated by reference into the
                  Registration Statement or the prospectus (after the initial
                  filing of such Registration Statement) provide copies of such
                  document to counsel for the Selling Stockholders and to each
                  managing underwriter, if any, and make Newco's
                  representatives reasonably available for discussion of such
                  document and make such changes in such document concerning
                  the Selling Stockholders prior to the filing thereof as
                  counsel for such Selling Stockholders or underwriters may
                  reasonably request;

                           (xii)    furnish to each Selling Stockholder and
                  managing underwriter, if any, without charge, at least one
                  signed copy of the Registration Statement and any
                  post-effective amendments thereto, including financial
                  statements and schedules, all documents incorporated therein
                  by reference and all exhibits (including those incorporated
                  by reference);

                                       8
<PAGE>   9

                           (xiii)   cooperate with the Selling Stockholders and
                  managing underwriters, if any, to facilitate the timely
                  preparation and delivery of certificates not bearing any
                  restrictive legends representing the Registrable Shares to be
                  sold, and cause such Registrable Shares to be issued in such
                  denominations and registered in such names in accordance with
                  the underwriting agreement prior to any sale of Registrable
                  Shares to the underwriters or, if not an underwritten
                  offering, in accordance with the instructions of the Selling
                  Stockholders at least three business days prior to any sale
                  of Registrable Shares and instruct any transfer agent and
                  registrar of Registrable Shares to release any stop transfer
                  orders in respect thereof;

                           (xiv)    comply in all respects with Regulation M of
                  the Exchange Act (as defined below), and any successor rules
                  and regulations to Regulation M ("Regulation M"), during any
                  distribution of Registrable Shares pursuant to this
                  Agreement; and

                           (xv)     cause such Registrable Shares covered by a
                  Registration Statement to be listed on the principal exchange
                  or exchanges (including the Nasdaq Stock Market) on which the
                  Newco Common Stock is then listed upon the sale of such
                  Registrable Shares pursuant to such Registration Statement.

                  For purposes of this Agreement, "Exchange Act" shall mean the
         United States Securities Exchange Act of 1934, as amended, or any
         successor federal statute, and the rules and regulations of the
         Commission issued under such Act, as they may, from time to time, be
         in effect.

                  (b)      Subject to any rights under registration rights
         agreements which ANTEC Corporation is a party as of the date hereof,
         Newco agrees that if it shall previously have received a request for
         registration pursuant to Section 1 hereof and if such previous
         registration shall not have been withdrawn or abandoned, Newco shall
         not effect any registration of any of its securities under the
         Securities Act (other than a registration on Form S-4 or Form S-8 or
         any successor form which is then in effect), whether or not for sale
         for its own account, until a period of 60 days, shall have elapsed
         from the effective date of such previous registration.

                  (c)      Newco's obligations under this Agreement with
         respect to a Selling Stockholder shall be conditioned upon such
         Selling Stockholder's compliance with the following:

                           (i)      Such Selling Stockholder shall cooperate
                  with Newco in connection with the preparation of the
                  Registration Statement, and for so long as Newco is obligated
                  to file and keep effective the Registration Statement, shall
                  provide to Newco, in writing, for use in the Registration
                  Statement, all such information regarding the Selling
                  Stockholder and its plan of distribution of the Registrable
                  shares as may be reasonably requested to enable Newco to
                  prepare the

                                       9
<PAGE>   10

                  Registration Statement and prospectus covering the
                  Registrable Shares, to maintain the currency and
                  effectiveness thereof and otherwise to comply with all
                  applicable requirements of law in connection therewith.

                           (ii)     During such time as such Selling
                  Stockholder may be engaged in a distribution of the
                  Registrable Shares, such Selling Stockholder shall comply
                  with Regulation M and pursuant thereto it shall, among other
                  things: (A) not engage in any stabilization activity in
                  connection with the securities of Newco in contravention of
                  such regulation; (B) distribute the Registrable Shares solely
                  in the manner described in the Registration Statement; (C)
                  cause to be furnished to each broker through whom the
                  Registrable Shares may be offered, or to the offeree if an
                  offer is not made through a broker, such copies of the
                  prospectus covering the Registrable Shares and any amendment
                  or supplement thereto and documents incorporated by reference
                  therein as may be required by law; and (D) not bid for or
                  purchase any securities of Newco or attempt to induce any
                  person to purchase any securities of Newco other than as
                  permitted under the Exchange Act.

                           (iii)    If the Registration Statement provides for
                  a Shelf Offering, then at least five (5) business days prior
                  to any distribution of the Registrable Shares, any Selling
                  Stockholder who is an "affiliated purchaser" (as defined in
                  Rule 100 of Regulation M) of Newco shall advise Newco in
                  writing of the date on which the distribution by such Selling
                  Stockholder will commence, the number of the Registrable
                  Shares to be sold and the manner of sale. Such Selling
                  Stockholder also shall inform Newco when each distribution of
                  such Registrable Shares is complete.

                           (iv)     Stockholder agrees and covenants that, upon
                  receipt of any notice from Newco of the happening of any
                  event of the kind described in Section 5(a)(v)(E) hereof,
                  Stockholder will forthwith discontinue disposition of
                  Registrable Shares pursuant to the registration statement
                  covering such Registrable Shares until Stockholder's receipt
                  of the copies of the supplemented or amended prospectus
                  contemplated by such section, and, if so directed by Newco,
                  Stockholder will deliver to Newco all copies, other than
                  permanent file copies, then in Stockholder's possession of
                  the most recent prospectus covering such Registrable Shares
                  at the time of receipt of such notice; provided, however,
                  that the Company shall use its reasonable best efforts to
                  promptly prepare and furnish to each such Selling Stockholder
                  and each underwriter, if any, a reasonable number of copies
                  of the supplemented or amended prospectus.

         6.       Indemnification.

                  (a)      By Newco. Newco agrees to indemnify and hold
         harmless, to the full extent permitted by law, each Selling
         Stockholder, its officers, directors and agents, and each person, if
         any, who controls any of the foregoing persons within the meaning of
         the Securities Act against all losses, claims, damages, liabilities
         and expenses, joint or several

                                      10
<PAGE>   11

         (including reasonable fees of one counsel for all Selling
         Stockholders) ("Losses"), to which each indemnified party may become
         subject under the Securities Act, state and provincial securities laws
         or otherwise in respect thereof insofar as such Losses arise out of or
         are based upon any untrue or alleged untrue statement of a material
         fact contained in any registration statement, prospectus or
         preliminary prospectus or any amendment thereof or supplement thereto
         (the "Disclosure Documents") or any omission or alleged omission to
         state therein a material fact required to be stated therein or
         necessary to make the statements therein (in the case of a prospectus,
         in the light of the circumstances under which they were made) not
         misleading, except insofar as the same are caused by or contained in
         any information with respect to such Selling Stockholder furnished in
         writing to Newco by such Selling Stockholder expressly for use
         therein. In connection with an underwritten offering, Newco will
         indemnify the underwriters thereof, their officers and directors and
         each person who controls such underwriters (within the meaning of the
         Securities Act) to the same extent as provided above with respect to
         the indemnification of the holders of Registrable Shares. Newco will
         reimburse each such indemnified party for all legal or other expenses
         reasonably incurred by such party (as incurred by such party) in
         connection with investigating or defending any such claims, including,
         subject to such indemnified party's compliance with the provisions of
         the last sentence of subsection (c) of this Section 6, any amounts
         paid in settlement of any litigation, commenced or threatened. The
         foregoing indemnity and reimbursement of expenses shall remain in full
         force and effect regardless of any investigation made by or on behalf
         of such indemnified party and shall survive the transfer of such
         Registrable Shares by such Selling Stockholder.

                  (b)      By the Selling Stockholders. In connection with any
         registration statement in which a Selling Stockholder is
         participating, each such Selling Stockholder shall furnish to Newco in
         writing such information with respect to such Selling Stockholder as
         Newco reasonably requests for use in connection with any such
         registration statement or prospectus and agrees to indemnify,
         severally and not jointly, to the extent permitted by law, Newco, the
         directors and officers of Newco and each person who controls Newco
         (within the meaning of the Securities Act) against any Losses
         resulting from any untrue or alleged untrue statement of a material
         fact or any omission or alleged omission of a material fact required
         to be stated in the Disclosure Documents or necessary to make the
         statements therein (in the case of a prospectus, in the light of the
         circumstances under which they were made) not misleading, to the
         extent, but only to the extent, that such untrue statement or omission
         is contained in any information with respect to such Selling
         Stockholder so furnished in writing by such Selling Stockholder
         expressly for use in the registration statement, provided that the
         liability of such Selling Stockholder pursuant to this Section 6(b)
         shall not exceed an amount equal to the net proceeds of the sale of
         Registrable Shares sold pursuant to such registration statement that
         are received by or for the benefit of such Selling Stockholder. Newco
         shall be entitled to receive indemnities from underwriters, selling
         brokers, dealer managers and similar securities industry professionals
         participating in the distribution to the same extent as provided above
         with respect to information so furnished in writing by such persons
         specifically for inclusion in

                                      11
<PAGE>   12

         any prospectus or registration statement. The Selling Stockholders
         shall reimburse each such indemnified party for all legal or other
         expenses reasonably incurred by such party in connection with
         investigating or defending any such claim, including, subject to such
         indemnified party's compliance with the provisions of the last
         sentence of subsection (c) of this Section 6, any amounts paid in
         settlement of any litigation, commenced or threatened. Newco and each
         Selling Stockholder hereby acknowledge and agree that, unless
         otherwise expressly agreed to in writing by such Selling Stockholder
         to the contrary, for all purposes of this Agreement the only
         information furnished or to be furnished to Newco for use in any such
         registration statement, preliminary, final or summary prospectus or
         amendment or supplement thereto are statements specifically relating
         to (i) transactions between such Selling Stockholder and its
         affiliates, as that term is defined in Rule 12b-2 of the Exchange Act
         ("Affiliates"), on the one hand, and Newco, on the other hand; (ii)
         the beneficial ownership of shares of Newco Common Stock by such
         Selling Stockholder and its Affiliates, (iii) the name and address of
         such Selling Stockholder, and (iv) any additional information about
         such Selling Stockholder or the plan of distribution (other than for
         an underwritten offering) that is required by law to be disclosed in
         any such document.

                  (c)      Third Party Claims. Promptly after the receipt by
         any party hereto of notice of any claim, action, suit or proceeding
         (whether commenced or threatened) by any person who is not a party to
         this Agreement (collectively, an "Action") which is subject to
         indemnification hereunder, such party (the "Indemnified Party") shall
         give reasonable written notice to the party from whom indemnification
         is claimed (the "Indemnifying Party"). The Indemnified Party shall be
         entitled, at the sole expenses and liability of the Indemnifying
         Party, to exercise full control of the defense, compromise or
         settlement of any such Action unless the Indemnifying Party, within a
         reasonable time after the giving of such notice by the Indemnified
         Party, shall: (i) admit in writing to the Indemnified Party, the
         Indemnifying Party's liability to the Indemnified Party for such
         Action under the terms of this Section 6; (ii) notify the Indemnified
         Party in writing of the Indemnifying Party's intention to assume the
         defense thereof and (iii) retain legal counsel reasonably satisfactory
         to the Indemnified Party to conduct the defense of such Action. The
         Indemnified Party and the Indemnifying Party shall cooperate with the
         party assuming the defense, compromise or settlement of any such
         Action in accordance herewith in any manner that such party reasonably
         may request. If the Indemnifying Party so assumes the defense of any
         such Action, the Indemnified Party shall have the right to employ
         separate counsel and to participate in (but not control) the defense,
         compromise, or settlement thereof, but the fees and expenses of such
         counsel shall be the expenses of the Indemnified Party unless (i) the
         Indemnifying Party has agreed to pay such fees and expenses, (ii) any
         relief other than the payment of money damages is sought against the
         Indemnified Party, (iii) the Indemnified Party shall have been advised
         by its counsel that there may be one or more legal defenses available
         to it which are different from or additional to those available to the
         Indemnifying Party or (iv) the Indemnified Party shall have been
         advised by counsel that representation of both parties by the same
         counsel is otherwise inappropriate under applicable standards of
         professional conduct, and, in any such case, the fees and expenses of
         such separate counsel shall be borne by the

                                      12

         Indemnifying Party. No Indemnifying Party shall settle or compromise
         any such Action in which any relief other than the payment of money
         damages is sought against any Indemnified Party unless the Indemnified
         Party consents in writing to such compromise or settlement. No
         Indemnified Party shall settle or compromise any such Action for which
         it is entitled to indemnification hereunder without the prior written
         consent of the Indemnifying Party, unless the Indemnifying Party shall
         have failed, after reasonable notice thereof, to undertake control of
         such Action in the manner provided above in this Section 6.

                  (d)      Contribution. If the indemnification provided for in
         subsections(a) or (b) of this Section 6 is unavailable to or
         insufficient to hold the indemnified party harmless under subsections
         (a) or (b) above in respect of any Losses referred to therein for any
         reason other than as specified therein, then the Indemnifying Party
         shall contribute to the amount paid or payable by such indemnified
         party as a result of such Losses in such proportion as is appropriate
         to reflect the relative fault of the indemnifying party on the one
         hand and such Indemnified Party on the other in connection with the
         statements or omissions which resulted in such Losses, as well as any
         other relevant equitable considerations. The relative fault shall be
         determined by reference to, among other things, whether the untrue or
         alleged untrue statement of a material fact or the omission or alleged
         omission to state a material fact relates to information supplied by
         (or omitted to be supplied by) Newco or the Selling Stockholder (or
         underwriter) and the parties' relative intent, knowledge, access to
         information and opportunity to correct or prevent such statement or
         omission. The amount paid or payable by an Indemnified Party as a
         result of the Losses referred to above in this subsection (d) shall be
         deemed to include any legal or other expenses reasonably incurred by
         such indemnified party in connection with investigating or defending
         any such action or claim. No person guilty of fraudulent
         misrepresentation (within the meaning of Section 11(f) of the
         Securities Act) shall be entitled to contribution from any person who
         was not guilty of such fraudulent misrepresentation. Notwithstanding
         anything in this Section 6(d) to the contrary, no Indemnifying Party
         (other than Newco) shall be required pursuant to this Section 6(d) to
         contribute any amount in excess of the net proceeds received by such
         Indemnifying Party from the sale of Registrable Shares in the offering
         to which the Losses of the Indemnified Parties relate, less the amount
         of any indemnification payment made by such Indemnifying Party
         pursuant to subsection (a) or (b) of this Section 6.

                  (e)      The indemnity agreements contained herein shall be
         in addition to any other rights to indemnification or contribution
         which any Indemnified Party may have pursuant to law or contract and
         shall remain operative and in full force and effect regardless of any
         investigation made or omitted by or on behalf of any Indemnified Party
         and shall survive the transfer of the Registrable Shares by any such
         party.

                  (f)      The indemnification and contribution required by
         this Section 6 shall be made by periodic payments of the amount
         thereof during the course of the investigation or defense, as and when
         bills are received or expense, loss, damage or liability is incurred.

         7.       Limitations on Subsequent Registration Rights; Priority.
Subject to the provisions of the TCI Registration Rights Agreement, Newco shall
not, without the prior written consent of Stockholders holding at least a
majority of the Registrable Shares then held by all Stockholders, enter into
any agreement with any holder or prospective holder of any securities of Newco
which grants such holder or prospective holder rights to include securities of
Newco in any Registration Statement any of which material rights are more
favorable than those provided to Stockholders hereunder, without also offering
to Stockholders such more favorable material rights.

         8.       Rule 144 Requirements. Newco agrees to:

                  (a)      make and keep current public information about Newco
available, as those terms are understood and defined in Rule 144;

                  (b)      use its reasonable best efforts to file with the
Commission in a timely manner all reports and other documents required of Newco
under the Securities Act and the Exchange Act; and

                  (c)      furnish to any holder of Registrable Shares upon
request (i) a written statement by Newco as to its compliance with the
reporting requirements of Rule 144 and of the Securities Act and the Exchange
Act, (ii) a copy of the most recent annual or quarterly report of Newco and
(iii) such other reports and documents of Newco as such holder may reasonably
request to avail itself of any similar rule or regulation of the Commission
allowing it to sell any such securities without registration.

         9.       Miscellaneous.

                  (a)      Notices. All notices, requests, demands, waivers and

                  (b)      Entire Agreement. This Agreement, together with the
TCI Registration Rights Agreement, constitutes the entire agreement among the
parties hereto and supersedes all prior agreements and understandings, oral and
written, between the parties hereto with respect to the subject matter hereof.

                  (c)      Binding Effect; Benefit. This Agreement shall insure
to the benefit of and be binding upon the parties hereto and their respective
successors and assigns. Nothing in this Agreement, expressed or implied, is
intended to confer on any person other than the parties hereto or their
respective successors and assigns, any rights, remedies, obligations or
liabilities under or by reason of this Agreement, other than rights conferred
upon indemnified persons under Section 6 and rights conferred upon Permitted
Transferees. Nothing in this Agreement shall be deemed to create an independent
obligation on the part of any Stockholder to sell any Registrable Shares
pursuant to any effective registration statement.

                  (d)      Termination. This Agreement shall terminate upon the
first such instance as the Stockholders, collectively, cease to own at least
two percent (2%) of the outstanding Newco Common Stock. Notwithstanding the
foregoing, the rights, duties and obligations of Newco and the Stockholders
under Section 6 shall survive the termination of this Agreement.

                  (e)      Amendment and Modification. This Agreement may be
amended or modified only by an instrument in writing signed by or on behalf of
such party and any other person then a Stockholder. Any term or provision of
this Agreement may be waived in writing at any time by the party which is
entitled to the benefits thereof.

                  (f)      Enforceability. Any term or provision of this
Agreement which is invalid or unenforceable in any jurisdiction shall, as to
such jurisdiction, be ineffective to the extent of such invalidity or
unenforceability without rendering invalid or unenforceable the remaining terms
and provisions of this Agreement or affecting the validity or enforceability of
any of the terms or provisions of this Agreement in any other jurisdiction.

                  (g)      Equitable Remedies. The parties hereto acknowledge
that there would be no adequate remedy at law if any party fails to perform any
of its obligation hereunder, and, accordingly, agree that each party, in
addition to any other remedy to which it may be entitled at law or in equity,
shall be entitled to injunctive relief, including specific performance, to
enforce such obligations without the posting of any bond, and, if any action
should be brought in equity to enforce any of the provisions of this Agreement,
none of the parties hereto shall raise the defense that there is an adequate
remedy at law.

                  (h)      Section Headings. The section headings contained in
this Agreement are inserted for reference purposes only and shall not affect
the meaning or interpretation of this Agreement.

                  (i)      Counterparts. This Agreement may be executed in
counterparts, each of which shall be deemed to be an original, and all of which
together shall be deemed to be one and the same instrument.

                  (j)      Applicable Law. This Agreement and the legal
relations between the parties hereto shall be governed by and construed in
accordance with the laws of the State of Delaware, without regard to the
conflict of laws thereof.

         2.08.    LIABILITY OF MEMBERS. Except as otherwise expressly provided
by the Act, the debts, obligations and liabilities of the Company, whether
arising in contract, tort or otherwise, shall be solely the debts, obligations
and liabilities of the Company, and no Member shall be obligated personally for
any such debt, obligation or liability of the Company solely by reason of being
a Member. Without limiting the foregoing, (a) no Member, in its capacity as a
Member, shall have any liability or obligation to restore any negative balance
in its Capital Account, and (b) the failure of the Company to observe any
formalities or requirements relating to exercise of its powers or management of
its business or affairs under this Agreement or the Act shall not be grounds for
imposing personal liability on the Members for liabilities of the Company.

         2.09.    NO PARTNERSHIP. The Company is not intended to be a general
partnership, limited partnership or joint venture, and no Member shall be
considered to be a partner or joint venture of any other Member, for any
purposes other than foreign and domestic federal, state, provincial and local
income tax purposes, and this Agreement shall not be construed to suggest
otherwise.

         2.10.    TITLE TO COMPANY PROPERTY. All property owned by the Company,
whether real or personal, tangible or intangible, shall be deemed to be owned by
the Company as an entity, and no Member, individually, shall have any ownership
of such property. The Company may hold any of its assets in its own name or in
the name of its nominee, which nominee may be one or more trusts. Any property
held by a nominee trust for the benefit of the Company shall, for purposes of
this Agreement, be treated as if such property were directly owned by the
Company.

         2.11.    NO INDIVIDUAL AUTHORITY. No Member shall, without the express,
prior written consent of the Managing Member, take any action for or on behalf
of or in the name of the Company, or assume, undertake or enter into any
commitment, debt, duty or obligation binding upon the Company, except for
actions expressly provided for in this Agreement, and any action taken in
violation of the foregoing limitation shall, to the fullest extent permitted by
law, be void.

         2.12.    INVESTMENT REPRESENTATIONS.

                  (a)      Investment Intent. Each Member hereby represents and
warrants to each other Member and to the Company that it has acquired its
interest in the Company solely for its own account with the intention of holding
such interest for investment purposes only.

                  (b)      Unregistered Interests. Each Member hereby
acknowledges that it is aware that its Interests have not been registered under
the Securities Act or under any state securities laws. Each Member further
understands and acknowledges that its representations and warranties contained
in this Section 2.13 are being relied upon by the Company and by the other
Members as the basis for the exemption of the Members' Interests in the Company
from the registration requirements of the Securities Act and under all state
securities laws. Subject to Section 6.05(c), each Member further acknowledges
that the Company will not and has no obligation to recognize any sale, transfer,
or assignment of a Member's Interest in the Company to any Person unless and
until the provisions of Article VIII hereof applicable to such sale, transfer or
assignment have been fully satisfied.

                                   ARTICLE III

                   CAPITAL CONTRIBUTIONS; ADDITIONAL FINANCING

         3.01.    CAPITAL ACCOUNTS. For each Member (and each permitted
assignee), the Company shall establish and maintain a separate Capital Account.
The initial Capital Account balances of the Members as of the Closing Date shall
be set forth in Schedule A.

                                       11
<PAGE>   16

         3.02.    CAPITAL CONTRIBUTIONS. Pursuant to the Agreement and Plan of
Reorganization, on the Closing Date, Nortel shall contribute the amounts
specified in Section 4.02 of the Agreement and Plan of Reorganization. In
exchange for such contribution, the Company shall issue to Nortel the Class B
Interest.

         3.03.    OTHER CONTRIBUTIONS: NO WITHDRAWAL OF OR INTEREST ON CAPITAL.
Each Class A Member may contribute to the capital of the Company any amounts
requested by the Managing Member to be so contributed. The Class B Member may
not further contribute to the capital of the Company and shall have no
obligation to make any further or additional Capital Contribution. No interest
shall accrue on any Capital Contributions, and no Member shall have the right to
withdraw or to have returned or be repaid any Capital Contribution made by it or
to receive any other payment in respect of its Interest, except as specifically
provided in this Agreement (including, without limitation, Sections 8.02 and
9.03).

         3.04.    THIRD PARTY LOANS. In the event that the Company requires
additional funds to carry out its purposes, to conduct its business and affairs,
or to meet its obligations, or to make any expenditure authorized by this
Agreement, the Company may borrow funds from such Persons, and on such terms and
conditions, as may be approved by the Managing Member.

         3.05.    MEMBER LOANS. Any Member, including the Managing Member, may
lend funds to the Company to carry out its purposes, to conduct its business and
affairs, or to meet its obligations, or to make any expenditure authorized by
this Agreement, in each case upon the approval of the Managing Member (provided
that the Class B Member shall have no obligation to lend any such funds to the
Company, and this Agreement shall not be construed to suggest otherwise). Unless
otherwise agreed by the lender and the Managing Member, a Member Loan shall bear
interest at the "prime rate" published by The Wall Street Journal plus two
percent (2%) and shall be payable out of Cash Flow, Capital Proceeds or on
liquidation as provided in Sections 4.01, 4.02 and 9.03, respectively; provided
that in all events all other terms of any Member Loan shall be commercially
reasonable and established on an arms-length basis.

         3.06.    REDUCTION OF CAPITAL ACCOUNTS. Any distribution to a Member,
whether pursuant to Section 4.01 or 4.02 or any other Section of this Agreement,
shall reduce the amount of such Member's Capital Account in accordance with
Section 3.07, but no adjustment in the Interests of any Member shall be made on
account of any such distribution, except as otherwise specifically provided in
this Agreement.

         3.07.    CAPITAL ACCOUNTS.

                  (a)      "Capital Account" means an account that shall be
maintained for each Member and which, as of any given date, shall be an amount
equal to the following:

                           (i)      The aggregate amount of cash that has been
         contributed to the capital of the Company as of such date by or on
         behalf of such Member; plus

                                       12
<PAGE>   17

                           (ii)     The agreed upon Gross Asset Value (as of the
         date of contribution) of any property other than cash that has been
         contributed to the capital of the Company as of such date by such
         Member and the amount of liabilities assumed by any such Member under
         Section 752 of the Code or which is secured by any Company property
         distributed to such Member; plus

                           (iii)    The aggregate amount of the Company's Net
         Profit that has been allocated to such Member as of such date pursuant
         to the provisions of Section 5.01 or any items of income or gain which
         are specially allocated to such Member or other positive adjustment
         required by the Regulations and which have not been previously taken
         into account in determining Capital Accounts; minus

                           (iv)     The aggregate amount of the Company's Net
         Loss that has been allocated to such Member as of such date pursuant to
         Section 5.02 and the amount of any item of expense deduction or loss
         which is specially allocated to such Member; and minus

                           (v)      The aggregate amount of cash and the agreed
         upon Gross Asset Value of all other property (as of the date of
         distribution) that has been distributed to or on behalf of such Member
         and the amount of any liabilities of such Member assumed by the Company
         under Section 752 of the Code or which are secured by any property
         contributed by such Member to the Company or other negative adjustment
         required by the Regulations and which have not been previously taken
         into account in determining Capital Accounts.

                  (b)      Upon the sale, transfer, assignment or other
disposition of an Interest in the Company after the date of this Agreement, the
Capital Account of the transferor Member that is attributable to the transferred
Interest will be carried over to the transferee Member. In the case of a sale or
exchange of any Interest in the Company at a time when an election under Code
Section 754 is in effect, the Capital Account of the transferee Member shall not
be adjusted to reflect the adjustments to the adjusted tax bases of Company
property required under Code Sections 754 and 743, except as otherwise permitted
by Regulation Section 1.704-1(b)(2)(iv)(m).

                  (c)      The foregoing provisions and the other provisions of
this Agreement relating to the maintenance of Capital Accounts are intended to
comply with Regulation Section 1.704-1(b), and shall be interpreted and applied
in a manner consistent with such Regulation. In the event the Members shall
determine that it is prudent to modify the manner in which the Capital Accounts,
or any debits or credits thereto (including, without limitation, debits or
credits relating to liabilities that are secured by contributed or distributed
property or that are assumed by the Company or the Members), are computed in
order to comply with such Regulation, the Managing Member may make such
modification, provided that such modification is not likely to have a material
effect on the amounts distributable to any Member pursuant to Section 9.03
hereof upon the dissolution of the Company.

                                       13
<PAGE>   18

         3.08.    NEGATIVE CAPITAL ACCOUNTS. Any Member having a deficit or
negative balance in its Capital Account shall not be required to restore such
deficit capital amount or otherwise to contribute capital to the Company to
restore its Capital Account.

         3.09.    NO RESIGNATION OR WITHDRAWAL OF CAPITAL. Except as provided in
Article VIII, no Member shall have the right to resign or withdraw from the
Company or to withdraw any portion of the capital of the Company at any time.
Upon dissolution of the Company, the Members' capital shall be distributed
pursuant to Section 9.03 hereof.

                                   ARTICLE IV

                                  DISTRIBUTIONS

         4.01.    DISTRIBUTION OF CASH FLOW. Subject to Section 9.03, the
Company shall distribute Cash Flow as follows: (a) to the Class B Member to make
the redemption payments specified in Section 8.02 in respect of the Class B
Interest; (b) to repay amounts borrowed pursuant to Section 3.05 as and when
determined by the Managing Member; and (c) to the Class A Members as and when
determined by the Managing Member; provided that it is acknowledged and agreed
that (x) this Section 4.01 is not intended to, and shall not, override or
otherwise qualify the limitations on the Company's obligations contained in
Section 8.02 hereof, and (y) the Company shall not have any obligation to make,
and shall not make, any redemption payments with respect to the Class B Interest
pursuant to Section 4.01(a) unless and until such redemption payment is
permitted by Section 8.02.

         4.02.    DISTRIBUTION OF CAPITAL PROCEEDS. The Company shall distribute
to the Members Capital Proceeds as provided herein (including, without
limitation, Section 8.02 and Section 9.03), and otherwise as and when determined
by the Managing Member; provided that it is acknowledged and agreed that (x)
this Section 4.02 is not intended to, and shall not, override or otherwise
qualify the limitations on the Company's obligations contained in Section 8.02
hereof, and (y) the Company shall not have any obligation to make, and shall not
make, any redemption payments with respect to the Class B Interest pursuant to
Section 4.02 unless and until such redemption payment is permitted by Section
8.02.

         4.03.    LIMITATIONS ON DISTRIBUTIONS. Except as provided in Sections
4.01, 4.02, 4.04, 8.02 and 9.03, distributions of cash or other property shall
be made to the Members at such time or times, in such amounts, and in such
manner, as the Managing Member shall determine. Notwithstanding any provision to
the contrary contained in this Agreement, the Company shall not make a
distribution to any Member on account of its Interest if such distribution would
violate the Act or other applicable law or, in the case of a distribution with
respect to the Class B Interest, violate Section 8.02(b) or exceed the Class B
Unreturned Capital plus any unpaid Class B Return.

         4.04.    CLASS B MEMBER DISTRIBUTION PREFERENCE IN BANKRUPTCY. If (a) a
Bankruptcy occurs as to the Company and (b) an exchange described in Section
8.03 has not occurred, no

                                       14
<PAGE>   19

other Member of the Company shall be entitled to receive any distributions under
this Agreement until the Class B Member has received a distribution of (i) the
Class B Unreturned Capital and (ii) any unpaid Class B Return. Nothing herein
shall be construed to permit a distribution to the Class B Member that otherwise
is prohibited by the Subordination Agreement.

         4.05.    TAX WITHHOLDING. If the Company incurs any obligation to pay
any amount in respect of taxes (including withholding taxes and any interest,
penalties or additions to tax) imposed on income of or distributions made to any
Member or former Member, any amount so required to be paid by the Company with
respect to such Person shall be treated for all purposes of this Agreement as if
it had been loaned to such Person, and the Managing Member shall cause the
Company to give prompt written notice to such Person of the date and amount of
such loan. Any withholding taxes withheld pursuant to this Section 4.05 shall be
withheld at the maximum applicable statutory rate under the applicable tax law
unless the Managing Member shall have received an opinion of counsel or other
evidence, satisfactory to the Managing Member in its reasonable discretion, to
the effect that a lower rate is applicable or that no withholding is applicable.
Each Member covenants, for itself, its successors, assigns, heirs and personal
representatives, that such Person shall pay to the Company at any time after
notice of the loan has been given, but not later than twenty (20) days after the
Company delivers a written demand to such Person for such repayment (which
demand may be made at any time prior to or after the dissolution of the Company
or the withdrawal of such Person or its predecessors from the Company);
provided, however, that if any such repayment is not made within such 20-day
period, such Person shall pay interest to the Company at a rate equal to the
"prime rate" published by The Wall Street Journal, adjusted daily, for the
entire period commencing on the date on which the Company paid such amount and
ending on the date on which such Person repays such amount to the Company
together with all accrued but previously unpaid interest. The Company shall (1)
collect such unpaid amounts (including interest) from any Company distributions
that otherwise would be made to such Person and/or (2) subtract from the Capital
Account of such Person, no later than the day prior to the Company's initial
liquidating distribution, any such unpaid amounts (plus unpaid interest) not so
collected, in each case treating the amount so collected or subtracted as having
been distributed to such Person at the time of such collection or subtraction.

         4.06.    NO LIMITATIONS ON REDEMPTION. For the avoidance of doubt,
notwithstanding anything to the contrary in this Agreement (including, without
limitation, the provisions of Section 4.01 and Section 4.02 to the extent they
may be construed to imply that the Company shall not, unless otherwise
determined by the Managing Member, be obligated to distribute assets other than
Cash Flow and Capital Proceeds in connection with the redemption of the Class B
Interest required by the provisions of Section 8.02 hereof), the provisions of
this Article IV shall be in all respects subject to, and shall not in any way
limit or restrict, the Company's obligations under Section 8.02(a) and Section
9.03 (in each case subject to the limitations set forth in Section 8.02(b) and
the Subordination Agreement), except for amounts owed to the Company pursuant to
Section 4.05.

                                    ARTICLE V

                    ALLOCATION OF NET PROFITS AND NET LOSSES

         5.01.    NET PROFIT. Except as otherwise provided in this Article V,
all Net Profit of the Company for each Fiscal Year shall be allocated to the
Members as follows:

                  (a)      First, to the Members, pro rata in proportion to the
cumulative allocations of Net Loss to each Member pursuant to Section 5.03 until
the cumulative Net Profit allocated to each Member pursuant to this clause (a)
is equal to the cumulative Net Loss allocated to such Member pursuant to Section
5.03 (such Net Profit to be allocated in reverse chronological order of the
allocation of the Net Loss pursuant to Section 5.03 which has not been
previously offset by an allocation under this Section 5.01(a));

                  (b)      Second, to the Class A Members, pro rata in
proportion to the cumulative Net Loss allocated to each Class A Member pursuant
to Section 5.02 until the cumulative Net Profit allocated to each Class A Member
pursuant to this clause (b) is equal to the cumulative Net Loss allocated to
such Class A Member pursuant to Section 5.02 (such Net Profit to be allocated in
reverse chronological order of the allocation of the Net Loss pursuant to
Section 5.02 which has not been previously offset by an allocation under this
Section 5.01(b)); and

                  (c)      Thereafter, to the Class A Members pro rata in
proportion to their then respective Class A Sharing Ratios.

         5.02.    NET LOSS. Except as otherwise provided in this Agreement, all
Net Loss of the Company for each Fiscal Year shall be allocated to the Class A
Members pro rata in proportion to their then respective Class A Sharing Ratios.

         5.03.    LIMITATION ON NET LOSS ALLOCATIONS. Notwithstanding any
provision of this Agreement to the contrary, except as otherwise specifically
provided in this Section 5.03 in no event shall Net Loss be allocated to a
Member if such allocation would result in such Member's having a negative
Adjusted Capital Account Balance at the end of any Fiscal Year. All Net Loss in
excess of the limitation set forth in this Section 5.03 shall be allocated to
any remaining Member with a positive Adjusted Capital Account Balance, and if
all such Adjusted Capital Account Balances are zero or negative, to the Class A
Members pursuant to Section 5.02 above.

         5.04.    OTHER ITEMS. Except as provided herein, for tax purposes, all
items of income, gain, loss, deduction or credit shall be allocated in the same
manner as are Net Profit and Net Loss.

         5.05.    SPECIAL ALLOCATIONS. Notwithstanding Sections 5.01, 5.02 and
5.03 above, the following allocations of Net Profit or Net Loss or items thereof
shall be made in the following order of priority:

                                       16
<PAGE>   21

                  (a)      MINIMUM GAIN CHARGEBACK. To the extent required by
Regulation Section 1.704-2(f), if there is a net decrease in "partnership
minimum gain" (within the meaning of Regulation Section 1.704-2(b)(2)), then
each Member will be allocated items of income and gain (calculated in accordance
with clauses (i), (ii) and (iii) of the definition of "Net Profit" or "Net
Loss"), before any other allocation of Net Profit or Net Loss, equal to that
Member's share of the net decrease in partnership minimum gain determined in
accordance with Regulation Section 1.704-2(g)(2).

                  (b)      MEMBER MINIMUM GAIN CHARGEBACK. If a Member suffers a
net decrease in "partner nonrecourse debt minimum gain" (within the meaning of
Regulation Section 1.704-2(i)(4)) in any Fiscal Year, then that Member will be
allocated items of income and gain (calculated in accordance with clauses (i),
(ii) and (iii) of the definition of "Net Profit" or "Net Loss") to the extent
required by Regulation Section 1.704-2(i)(4).

                  (c)      QUALIFIED INCOME OFFSET. In the event any Member
unexpectedly receives any adjustments, allocations, or distributions described
in Regulation Sections 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5) or
1.704-1(b)(2)(ii)(d)(6), items of Company income and gain (calculated in
accordance with clauses (i), (ii) and (iv) of the definition of "Net Profit" or
"Net Loss") shall be specially allocated to each such Member in an amount and
manner sufficient to eliminate, to the extent required by the Regulations, the
negative Adjusted Capital Account Balance of such Member as quickly as possible,
provided that an allocation pursuant to this clause (c) shall be made if and
only to the extent that such Member would have a negative Adjusted Capital
Account Balance after all other allocations provided for in this Article V. This
provision is intended to constitute a "qualified income offset" within the
meaning of Regulation Section 1.704-2(b)(ii)(d).

                  (d)      GROSS INCOME ALLOCATION. In the event any Member has
a deficit Capital Account at the end of any Fiscal Year that is in excess of the
sum of (i) the amount such Member is obligated to restore (pursuant to the terms
of a promissory note to the Company or otherwise), and (ii) the amount such
Member is deemed to be obligated to restore pursuant to the penultimate sentence
of each of Regulation Sections 1.704-2(g)(1)(ii) and 1.704-2(i)(5) each such
Member shall be specially allocated items of Company income and gain in the
amount of such excess as quickly as possible, provided that an allocation
pursuant to this clause (d) shall be made if and only to the extent that such
Member would have a deficit Capital Account in excess of such sum after all
other allocations provided for in this Article V have been tentatively made as
if Section 5.05(c) and this clause (d) were in not in this Article V.

                  (e)      NONRECOURSE DEDUCTIONS. If there are any "nonrecourse
deductions" (within the meaning of Regulation Sections 1.704-2(b)(1) and
1.704-2(c)) in a Fiscal Year, then such deductions shall be allocated to the
Class A Members pro rata in accordance with their then respective Class A
Sharing Ratios.

                  (f)      MEMBER NONRECOURSE DEDUCTIONS. If there are any
"partner nonrecourse deductions" (within the meaning of Regulation Section
1.704-2(i)(1)) in a Fiscal Year, then such deductions will be allocated to the
Member who bears the economic risk of loss for the "partner

                                       17
<PAGE>   22

nonrecourse liability" (within the meaning of Regulation Section 1.704-2(b)(4))
to which the deductions are attributable.

                  (g)      SECTION 754 ADJUSTMENTS. To the extent an adjustment
to the adjusted tax basis of any Company asset pursuant to Code Section 734(b)
or Code Section 743(b) is required, pursuant to Regulation Section
1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts,
the amount of such adjustment to Capital Accounts shall be treated as an item of
gain (if the adjustment increases the basis of the asset) or loss (if the
adjustment decreases such basis) and such gain or loss shall be specially
allocated to the Members in a manner consistent with the manner in which their
Capital Accounts are required to be adjusted pursuant to such Section of the
Regulations.

                  (h)      CLASS B PRIORITY ALLOCATION. At the end of each
Fiscal Year, all or part of the Company items of gross income or gross gain for
the Fiscal Year remaining after the application of Sections 5.05(a)-(g), if any,
shall be specially allocated to the Class B Member(s), pro rata in accordance
with their Class B Interests, in proportion to and to the extent of the excess
of (x) the cumulative distributions of the Class B Return pursuant to this
Agreement from the Closing Date to the end of such Fiscal Year, or with respect
to such Fiscal Year, over (y) the cumulative items of gross income or gross gain
previously allocated to such Class B Member pursuant to this Section 5.05(h).

         5.06.    CURATIVE ALLOCATIONS. The allocations set forth in Sections
5.05(a) through 5.05(e) (the "Regulatory Allocations") are intended to comply
with certain requirements of Regulation Sections 1.704-1(b) and 1.704-2(b).
Notwithstanding any other provisions of this Agreement, other than the
Regulatory Allocations, the Regulatory Allocations shall be taken into account
in allocating other items of income, gain, loss and deduction among the Members
so that, to the extent possible, the net amount of such allocations of other
items and the Regulatory Allocations to each Member shall be equal to the net
amount that would have been allocated to such Member if the Regulatory
Allocations had not occurred. The Members shall, with respect to each Fiscal
Year, apply the provisions of this Section 5.06 in whatever manner is likely to
minimize the economic distortions that might otherwise result from the
Regulatory Allocations.

         5.07.    OTHER ALLOCATION RULES. The following rules shall apply for
purposes of making tax allocations:

                  (a)      "Excess nonrecourse liabilities" of the Company
within the meaning of Regulations Section 1.752-3(a)(3), shall be allocated to
the Class A Members in proportion to their respective Class A Sharing Ratios.

                  (b)      For purposes of determining the Net Profit, Net Loss
or any other items allocable to any period, Net Profit, Net Loss and any such
other items shall be determined on a daily, monthly or other basis, pursuant to
any permissible method under Code Section 706 and the Regulations promulgated
thereunder as selected by the Managing Member in its reasonable discretion
without regard to the tax consequences to any Member.

                                       18
<PAGE>   23

                  (c)      The Members are aware of the income tax consequences
of the allocations made by this Article V and hereby agree to be bound by the
provisions of this Article V in reporting their shares of the Company income and
loss for income tax purposes.

                  (d)      To the extent permitted by Regulations Section
1.704-2(h)(3), the Members shall treat distributions of Capital Proceeds as not
allocable to an increase in "partnership minimum gain" (within the meaning of
Regulation Section 1.704-2(b)(2)) to the extent the distribution does not cause
or increase a deficit balance in the Adjusted Capital Account Balance of any
Member.

         5.08.    SECTION 704(C) ALLOCATION. Notwithstanding any other provision
of this Agreement to the contrary, any gain or loss and any depreciation and
cost recovery deductions recognized by the Company for income tax purposes in
any Fiscal Year with respect to all or any part of the Company's property that
is required or permitted to be allocated among the Members in accordance with
Section 704(c) of the Code and any Regulations promulgated thereunder so as to
take into account the variation, if any, between the adjusted tax basis of such
property at the time of its contribution and the Gross Asset Value of such
property at the time of its contribution, shall be allocated to the Members for
income tax purposes using any method described in Section 1.704-3 of the
Regulations as selected by the Members. If and when the Capital Accounts of the
Members are adjusted pursuant to the definition of "Gross Asset Value" or
otherwise pursuant to Regulation Sections 1.704-1(b)(2)(iv)(f) or (g) with
respect to a revaluation of any asset of the Company, then subsequent
allocations of income, gain, loss, and deduction, including without limitation
depreciation or deductions for cost recovery with respect to such asset, shall
take into account any variation between the then existing adjusted basis of such
asset for federal income tax purposes and the agreed value of such asset, as
such computations may be required under Sections 704(b) and 704(c) of the Code
and Regulation Section 1.704-1(b)(4)(i). Any elections or other decisions
relating to such allocations shall be made by the Managing Member in its
reasonable discretion without regard to the tax consequences to any Member.

                                   ARTICLE VI

                                   MANAGEMENT

         6.01.    MANAGEMENT OF THE COMPANY.

                  (a)      The management of the Company is fully reserved to
the Class A Members, and the Company shall not have non-member "managers," as
such term is used in the Act. Subject to the other provisions of this Agreement,
the powers of the Company shall be exercised by or under the authority of, and
the business and affairs of the Company shall be managed under the direction and
authority of the Managing Member who, in its sole and absolute discretion, shall
make all decisions and take all actions for the Company. Except as set forth in
the foregoing provisions of this Section 6.01 or expressly provided otherwise
elsewhere in this Agreement, no Member (in its capacity as a Member) has the
right, power or authority to act for or on behalf of the Company, to do any act
that would be binding on the Company, or to incur

                                       19
<PAGE>   24

any expenditures on behalf of the Company. Decisions or actions with respect to
the Company taken by the Managing Member in accordance with this Agreement shall
constitute decisions or actions by the Company and shall be binding on the
Company and each Member, officer and employee of the Company.

                  (b)      The Managing Member in its sole and absolute
discretion may delegate all or any of its duties hereunder to such other Persons
as the Managing Member deems necessary or desirable for the transaction of the
business of the Company, and in furtherance of any such delegation, shall have
the right to appoint, employ or contract with and pay reasonable compensation to
any other Persons, but in such event the Managing Member will not be released
from its responsibilities hereunder. Such Persons may, under the supervision of
the Managing Member, administer, or assist in the administration of the routine
day-to-day management of the Company and its business and affairs; may serve as
advisors and consultants to the Managing Member in connection with decisions
made by the Managing Member; may act as consultants, accountants,
correspondents, attorneys, brokers, escrow agents, or in any other capacity; and
may perform such other acts or services for the Company as the Managing Member
in its sole and absolute discretion may approve.

         6.02.    OFFICERS.

                  (a)      The officers of the Company shall consist of such
officers as may be determined by the Managing Member ("Officers"); provided,
however, that, if the Managing Member determines to establish any officer
position with a title expressly referenced in the DGCL or customarily used in
corporations organized under the DGCL, such Officer shall, to the maximum extent
possible, have the duties and responsibilities, and be deemed to have been
delegated to him by the Managing Member the rights, powers and authority,
associated with such officer position under the DGCL or customarily associated
with such officer position in such corporations, as the case may be.

                  (b)      No Officer need be a Member. Any two or more offices
may be held by the same person. Each Officer of the Company shall be required to
devote only such time to the business and affairs of the Company as may be
reasonably necessary for the discharge of his duties and responsibilities to the
Company in such capacity, and no Officer of the Company shall be required to
devote full time to the business and affairs of the Company unless the Managing
Member determines otherwise.

                  (c)      Except as otherwise provided by Law or by this
Agreement, each Officer shall hold office until his death, resignation or
removal, unless a different term is specified in the action of the Managing
Member designating him. Any Officer may resign by delivering his written
resignation to the Managing Member. Such resignation shall be effective upon
receipt unless it is specified to be effective at some other time or upon the
happening of some other event. Any Officer may be removed at any time, with or
without cause, by action of the Managing Member.

                                       20
<PAGE>   25

                  (d)      Except as the Managing Member may otherwise
determine, no Officer who resigns or is removed shall have any right to any
compensation as an Officer for any period following his resignation or removal,
or any right to damages on account of such removal, whether his compensation be
by the month or by the year or otherwise, unless such compensation is expressly
provided in a duly authorized written agreement with the Company.

                  (e)      The Managing Member may, in its discretion, fill any
vacancy occurring in any office of the Company for any reason or leave such
vacancy unfilled for such period as it may determine.

         6.03.    BINDING THE COMPANY. Except as the Managing Member may
generally or in any particular case or cases otherwise authorize, and subject to
the other provisions of this Agreement, all deeds, leases, contracts, bonds,
notes, checks, drafts or other obligations made, accepted or endorsed by the
Company shall be signed by the Managing Member or any one or more Officers of
the Company.

         6.04.    CONTRACTS WITH MEMBERS. The Company may engage in business
with, or enter into one or more agreements, leases, contracts or other
arrangements for the furnishing to or by the Company of funds, goods, services
or space with, any Member or Affiliate of a Member, and may pay reasonable
compensation in connection with such business, funds, goods, services or space.
Contracts with Members or Affiliates of Members, at the discretion of the
Managing Member, need not be in writing.

         6.05.    REQUIRED APPROVAL BY MEMBERS.

                  (a)      The following actions and decisions shall require the
affirmative approval, either by vote or by written consent, of Members
representing a majority of the Class A Interests:

                           (i)      to admit any new Member to the Company,
                  other than (A) as specifically permitted in this Agreement
                  (including, without limitation, Section 8.01(b)) or (B) as
                  provided for in Section 6.05(c) below;

                           (ii)     to institute proceedings to adjudicate the
                  Company a bankrupt, or consent to the filing of a bankruptcy
                  proceeding against the Company, or file a petition or answer
                  or consent seeking reorganization of the Company under the
                  Federal Bankruptcy Code or any other similar applicable
                  federal, state or foreign law, or consent to the filing of any
                  such petition against the Company, or consent to the
                  appointment of a receiver or liquidator or trustee or assignee
                  in bankruptcy or insolvency of the Company or of its property,
                  or make an assignment for the benefit of creditors of the
                  Company, or admit in writing the Company's inability to pay
                  its debts generally as they become due;

                           (iii)    to dissolve or wind-up the Company; and

                           (iv)     to merge or consolidate the Company with or
                  into another Person.

                                       21
<PAGE>   26

                  (b)      Subject only to Section 6.05(c) and the transactions
described in Section 8.03(a)(x), but notwithstanding anything else in this
Agreement to the contrary, for so long as any Class B Member remains a Member,
any (i) merger, consolidation or other business combination involving the
Company, (ii) conversion of the Company into any other form of entity, and (iii)
amendment of this Agreement (whether in connection with admission of a new
Member or otherwise), in each case causing or resulting in any direct or
indirect reduction of the benefits or increase of the detriments to be received
by the Class B Member hereunder, or otherwise adversely affecting the Class B
Interest, also shall require the prior affirmative written approval of a
majority of Class B Members.

                  (c)      The Members acknowledge that a full and complete
security interest in the Class A Interest has been granted by each of the Class
A Members to the Administrative Agent, for the benefit of the lenders pursuant
to the Senior Credit Facilities. Notwithstanding anything in this Agreement to
the contrary, the Administrative Agent and the lenders under, and the other
beneficiaries of, the Senior Credit Facilities, and their successors and
assigns, shall have the absolute and unconditional right to become Class A
Members, with no need for any approval, consent or other action of the Managing
Member, the Class A Members, the Class B Members, the Company or any other
Person, upon notice to the Managing Member in connection with the Administration
Agent's enforcement of such security interest after an Event of Default under
the Senior Credit Facilities, whether through foreclosure, Transfer in lieu of
foreclosure, other exercise of rights under the Senior Credit Facilities or
otherwise (including without limitation the exercise of rights of a secured
lender).

         6.06.    MEMBER ACTION. In the event that any matter is required to be
submitted to the Members for their approval under the terms of this Agreement or
the Act, the following provisions shall apply:

                  (a)      Meetings of the Members may be called by the Managing
Member. The Members entitled to vote may vote on any such matter at a meeting to
be held at such time and place as shall be designated by the Managing Member.
Any meeting of the Members may be held by conference telephone or similar
communication equipment so long as all Members entitled to vote participating in
the meeting can hear one another. Members entitled to vote on the matter shall
be given at least three (3) business days' prior written notice of any meeting;
provided that any Member may waive such notice prior to, at or after the
meeting. The notice shall specify the place, date and hour of the meeting and
the general nature of the business to be transacted.

                  (b)      Each Class A Member shall be entitled to vote in
accordance with its Class A Sharing Ratio of the Company. At any meeting of
Members, the presence of Class A Members holding at least a majority of the
Class A Sharing Ratios and the Class B Member when entitled to vote at such
meeting, shall constitute a quorum for the transaction of business. Except as
otherwise required by this Agreement or applicable Law, the affirmative vote of
Class A Members representing more than fifty percent (50%) of the Class A
Sharing Ratios is required to constitute approval of the Class A Members.

                                       22
<PAGE>   27

                  (c)      Any action that may be taken at any meeting of
Members may be taken without a meeting and without prior notice if a consent in
writing setting forth the action so taken is signed by all Members entitled to
vote on the matter. Any such written consent may be executed and given by
telecopy or similar electronic means and such consents shall be filed with the
minutes of the proceedings of the Members.

                  (d)      From time to time each Class A Member shall, by
notice to each other Member, designate one or more individuals who shall be
authorized to act under this Agreement for and on behalf of any such Class A
Member. Any written act, approval, consent or vote of any such representative
shall be deemed the act, approval, consent or vote of the Class A Member that
designated such representative. Each Class A Member may change any one or more
of its representatives at any time and from time to time by written notice to
each other Member.

                  (e)      Each Class A Member agrees to indemnify, hold
harmless and defend the other Members from any liability whatsoever arising out
of such other Member's relying on the written act, approval, consent or vote of
the indemnifying Class A Member's designated representatives. If any Member
relies on any act, approval, consent or vote of any other Person associated with
a Class A Member other than the designated representative, such relying Member
assumes the risk that such act, approval, consent or vote has not been duly
authorized by the Class A Member allegedly taking or giving such act, approval,
consent or vote, and shall not be entitled to rely on any such Person's apparent
or implied authority to perform or give any such act, approval, consent or vote
on behalf of the Class A Member allegedly performing or giving same. Upon the
transfer by a Class A Member of its entire Interest, any representative
appointed by such Class A Member shall automatically cease to be a
representative of such Class A Member hereunder effective upon notice of such
transfer to each other Member.

         6.07.    INDEMNIFICATION.

                  (a)      The Company shall, to the fullest extent permitted by
Law, indemnify any Person who was or is a party or is threatened to be made a
party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative, by reason of the fact
that such Person is an Officer of the Company, or is or was serving at the
request of the Company as a director or officer of any other Person (each, an
"Indemnitee"), against expenses (including attorneys' fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by him in
connection with such action, suit or proceeding with respect to any Indemnitee,
if he acted in good faith and in a manner he reasonably believed to be in or not
opposed to the interests of the Company, and, with respect to any criminal
action or proceeding, had no reasonable cause to believe was unlawful.

                  (b)      In addition, the Company may indemnify any Person who
is not an Indemnitee who was or is a party or is threatened to be made a party
to any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative, by reason of the fact that
such Person is an employee or agent of the Company, or was serving at

                                       23
<PAGE>   28

the request of the Company as an employee or agent of any other Person (each, an
"Optional Indemnitee"), against expenses (including attorneys' fees), judgments,
fines and amounts paid in settlement actually and reasonably incurred by him in
connection with such action, suit or proceeding if he acted in good faith and in
a manner he reasonably believed to be in or not opposed to the interests of the
Company, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe was unlawful.

                  (c)      To the extent that an Indemnitee has been successful
on the merits or otherwise in defense of any action, suit or proceeding referred
to in Section 6.07(a), or in defense of any claim, issue or matter therein, he
shall be indemnified against expenses (including attorneys' fees) actually and
reasonably incurred by him in connection therewith.

                  (d)      To the extent that an Optional Indemnitee has been
successful on the merits or otherwise in defense of any action, suit or
proceeding referred to in Section 6.07(b), or in defense of any claim, issue or
matter therein, he may be indemnified against expenses (including attorneys'
fees) actually and reasonably incurred by him in connection therewith.

                  (e)      The Company may pay the expenses (including
attorneys' fees) incurred by an Indemnitee or Optional Indemnitee in defending a
civil, criminal, administrative or investigative action, suit or proceeding
brought by a party against the Indemnitee or Optional Indemnitee in advance of
the final disposition of such action, suit or proceeding upon receipt of an
undertaking by or on behalf of such Indemnitee or Optional Indemnitee to repay
such amount if it shall ultimately be determined that he is not entitled to be
indemnified by the Company as authorized in this Section 6.07.

                  (f)      Any indemnification under this Section 6.07 (unless
ordered by a court) shall be made by the Company only as authorized in the
specific case upon a determination that indemnification of the Indemnitee or
Optional Indemnitee is proper in the circumstances because he has met the
applicable standard of conduct set forth in Section 6.07(a) and Section 6.07(b).
Such determination shall be made by the Managing Member.

                  (g)      The right of indemnification and reimbursement
provided in this Section 6.07 shall be in addition to any rights to which an
Indemnitee or Optional Indemnitee may otherwise be entitled and shall inure to
the benefit of the executors, administrators, personal representatives,
successors or assigns of each Indemnitee and Optional Indemnitee.

                  (h)      The rights to indemnification and reimbursement
provided for in this Section 6.07 may be satisfied only out of the assets of the
Company and to the extent of the Capital Contributions of the Members and none
of the Members shall be personally liable for any claim for indemnification or
reimbursement against the Company under this Section 6.07.

                  (i)      Except as set forth in Section 6.06(e) hereof, no
Managing Member and no Member (nor any director, shareholder, member, manager,
officer or employee of such Member, direct or indirect) shall be personally
liable or personally accountable to the Company or to any of the Members, in
damages or otherwise, for any error of judgment, for any mistake of fact or of

                                       24

law, or for any other act or thing which it may do or refrain from doing in
connection with the business and affairs of the Company, except for claims and
damages resulting from fraud, willful misconduct, bad faith, gross negligence or
a material breach of this Agreement.

                  (j)      To the fullest extent permitted by Law, the Company
(to the extent of its assets) hereby agrees to indemnify, defend and hold
harmless each Member and its Affiliates from and against any loss, expense, or
damage (including reasonable attorneys' fees and court costs) suffered by such
Member or its Affiliate by reason of anything the Company may do or refrain from
doing or such Member may do or refrain from doing hereafter for and on behalf of
the Company and in furtherance of its interests or by reason of such Member's
status as a Member of the Company.

                  (k)      Each Class A Member shall defend and indemnify the
Company and the other Members against, and shall hold them harmless from, any
damage, loss, liability or expense, including reasonable attorneys' fee, as and
when incurred by the Company or such other Members in connection with or
resulting from such indemnifying Class A Member's unauthorized actions, bad
faith, gross negligence, fraud, or willful misconduct.

                  (l)      The Company and each Member that is not a Class B
Member (each, an "Indemnifying Member"), jointly and severally, shall indemnify,
defend and hold harmless each Class B Member and its Affiliates from and against
any loss, cost, expense or damage (including, without limitation, attorneys'
fees and costs, costs of investigation and court and arbitration costs) suffered
by such Class B Member or any such Affiliate by reason of, or in connection
with, (i) anything the Company may do or refrain from doing or any Indemnifying
Member may do or refrain from doing hereafter in connection with, or in any way
relating to, the business and affairs of the Company, (ii) such Class B Member's
status as a Member of the Company and/or (iii) any action or omission by such
Class B Member (or any such Affiliate) taken or omitted to be taken in
connection with any exercise of, or any waiver of or failure to exercise, any of
such Class B Member's rights and powers under this Agreement. The Company and
each Indemnifying Member hereby agree that neither any Class B Member nor any
Affiliate of a Class B Member shall have any liability or accountability, in
damages or otherwise, to the Company, any Indemnifying Member or any of their
respective Affiliates with respect to any claim, cause of action, suit or
proceeding to the extent the same is based, in whole or in part, on any actual
or alleged action or omission of a type or kind described in clause (i), (ii) or
(iii) of the preceding sentence.

                  (iv)     the execution by the transferring Member and the
Assignee of a written agreement, in form and substance reasonably satisfactory
to the Managing Member, to indemnify and hold harmless the Company and the
non-transferring Members from and against any expense, loss or liability arising
out of such Transfer;

                  (v)      the execution by the transferring Member of a written
agreement, in form and substance reasonably satisfactory to the Managing Member,
acknowledging the termination of all the transferring Member's rights and
interests as a Member of the Company, effective immediately upon such Transfer;

                                       27

                  (vi)     if requested by the Managing Member, a written
opinion, delivered by and at the expense of the transferring Member, of counsel
for the Company, or other counsel reasonably satisfactory to the Managing
Member, that the Transfer will not result in (i) a violation of applicable law
or this Agreement; (ii) the Company being classified as an association or
taxable as a corporation for federal income tax purposes; (iii) the Company
being deemed terminated pursuant to Section 708(b)(1)(B) of the Code; or (iv) a
requirement for a registration of the transaction or the Interest under
applicable federal and state securities laws; and

                  (vii)    unless otherwise waived by the Managing Member, the
payment of the Assignee or the transferring Member of all expenses incurred by
the Company in connection with the Transfer and the admission of the Assignee to
the Company as a Member.

         (b)      Subject to compliance with non-waivable provisions of
applicable Law, any Class B Member may Transfer all or any portion of its Class
B Interest to any Person (whether one or more) at any time or from time to time,
with no need for any approval, consent or other action of the Managing Member,
the Class A Members, the Company or any other Person, provided that the
Transferee executes and delivers to the Transferor, the Managing Member and the
Administrative Agent (and receives a written acknowledgment from the
Administrative Agent of such delivery to the Administrative Agent) a written
instrument in substantially the form attached hereto as Exhibit 3 with the
blanks therein appropriately completed (the "Admission Agreement"). Upon
acquisition of all or any portion of the Class B Interest and execution and
delivery of the Admission Agreement and the Administrative Agent's
acknowledgment thereof, such Transferee shall, to the extent it was granted such
right by the terms of the Transfer by virtue of which such Transferee acquired
its Class B Interest, but with no need for any other approval, consent or other
action of the Managing Member, the Class A Members, the Company or any other
Person, be admitted to the Company as a Class B Member (unless it is already a
Class B Member at the time of such acquisition, execution and delivery). Any
attempt to transfer all or any portion of the Class B Interest without
compliance with the foregoing provisions shall be void ab initio.

         8.02.    REDEMPTION OF INTEREST OF CLASS B INTEREST.

                  (a)      PERIODIC REDEMPTION PAYMENTS. Subject to the
limitations of Section 8.02(b), the Company shall redeem the Class B Interest
held by the Class B Member for an aggregate amount equal to Initial Class B
Balance plus the Class B Return, for cash, as follows:

                           (i)      in quarterly installments, commencing on the
         first business day after the six-month anniversary of the Closing Date
         and thereafter on each successive three-month anniversary thereof, in
         the maximum aggregate amount permitted under Section 8.02(b) up to (and
         including) $33,000,000 per such installment (the "Maximum Quarterly
         Class B Redemption"), until redeemed in full (as defined below); and

                           (ii)     in any event, in full (as defined below), at
         the earlier of (1) the date occurring six (6) months after the
         Revolving Loan Commitment Termination Date, (2) a

                                       28
<PAGE>   33

         Change of Control of Newco, (3) Bankruptcy of Arris and (4)
         acceleration of the Senior Credit Facilities in accordance with the
         terms thereof.

For the purposes hereof, the Class B Interest shall be redeemed in full at such
time as the Class B Member has received cash redemption payments equal, in the
aggregate, to the sum of (i) Class B Unreturned Capital and (ii) the aggregate
Class B Return that has not been added to Class B Unreturned Capital, calculated
through and including the date of such redemption in full. Redemption payments
shall be applied first to the payment of accrued Class B Return that has not
been paid or added to Class B Unreturned Capital, and then to payment of Class B
Unreturned Capital.

                  (b)      CERTAIN LIMITATIONS. Until payment in full in cash of
all Senior Debt, the termination of any commitments to lend under the Senior
Credit Facilities and the cancellation or termination of any letters of credit
issued under the Senior Credit Facilities, no obligation to make redemption
payments shall arise, and no redemption payment shall be made, pursuant to
Section 8.02(a)(i), and no redemption payment shall be made pursuant to Section
8.02(a)(ii), unless and until:

                           (1)      prior to the date on which such redemption
         is made, the Borrowers have delivered to the Administrative Agent all
         financial statements, compliance certificates and other documents
         required to be delivered in connection with the most recent fiscal
         quarter ending prior to such date pursuant to the Senior Credit
         Agreement,

                           (2)      both immediately before and after giving pro
         forma effect to such redemption, no Event of Default shall have
         occurred and be continuing,

                           (3)      after giving pro forma effect to such
         redemption, the Borrowers shall have Excess Availability of at least
         $75 million, and

                           (4)      the Borrowers shall have delivered an
         officer's certificate of ANTEC signed by the chief financial officer of
         ANTEC certifying as to the foregoing clauses (1)-(3) and attaching a
         Borrowing Base Certificate demonstrating such Excess Availability, in
         each case in form and substance satisfactory to Administrative Agent;

         provided that, with respect to the fourth fiscal quarter of any fiscal
         year, Borrowers shall be deemed to have satisfied the part of the
         condition contained in clause (1) above requiring delivery of audited
         financial statements for the fiscal year ended at the end of the
         preceding fiscal quarter upon delivery of unaudited financial
         statements for such fiscal year in lieu of audited financial statements
         for such fiscal year and a certificate signed by the chief financial
         officer of ANTEC certifying that, when delivered, the audited financial
         statements shall not contain any material differences from the
         unaudited financial statements.

                  (c)      [Intentionally Omitted.]

                  (d)      COMPANY COVENANT. So as to enable the exercise of the
Class B Member's redemption rights in this Section 8.02, the Company shall, and
shall cause ANTEC to, comply with all reporting requirements and document
delivery requirements contained in the Senior Credit Facilities, make all
requisite certifications under the Senior Credit Facilities, and take all such
further actions as may be reasonably requested by the Class B Member to enable
the Company, to the fullest extent possible, to make all redemption payments
contemplated by this Section 8.02 timely and in full (provided, however, that in
no event shall the Company be required by any of the foregoing provisions of
this Section 8.02(d) to take any action prohibited by the terms of the Senior
Credit Facilities). The Company shall notify the Class B Member in writing of
any Default or Event of Default, any material breach by the Company of this
Section 8.02, or any amendment, restatement, amendment and restatement,
supplement to, or other modification thereof, in each case not later than five
(5) business days after occurrence thereof.

                  (e)      CESSATION OF CLASS B RIGHTS UPON COMPLETE REDEMPTION.
Upon the redemption in full of the Class B Interest as set forth in this Section
8.02, the Class B Interest shall be completely extinguished (including, without
limitation, any preference or other claim with respect to the Class B Interest)
and neither Nortel, nor any transferee permitted pursuant to Section 8.01, shall
have any rights, claims, duties, liabilities or obligations whatsoever with
respect to the Company under the Class B Interest or otherwise as a Member of
the Company, and shall cease to be a Member for all purposes (provided that,
notwithstanding anything in this Agreement to the contrary, the complete
redemption of the Class B Interest as set forth in this Section 8.02 shall not
constitute or operate as a waiver or release of, or have any other effect on,
(i) any breach or violation of the provisions of this Agreement occurring prior
to such complete redemption, or (ii) any of the Class B Member's rights and
remedies (whether at law or in equity) with respect thereto).

                  (f)      NO LIMITATION ON OTHER PAYMENTS. For the avoidance of
doubt, the foregoing limitations on the Company's redemption obligations with
respect to the Class B Interest shall not apply to any other payments to be made
by the Company or Newco (or any of their Affiliates) to Nortel Networks or any
of its Affiliates (including Nortel), whether pursuant to the Agreement and Plan
of Reorganization, any of the Ancillary Agreements, in connection with purchases
of goods and/or services or licenses of intellectual property rights as of and
after the date hereof, or otherwise (including payments with respect to the
Inventory and the German Inventory specified on Schedule 8.01(f) to the
Agreement and Plan of Reorganization).

         8.03.    MANDATORY EXCHANGE FOR NEW SECURITIES.

                  (a)      Until payment in full in cash of all Senior Debt, the
termination of all commitments to lend under the Senior Credit Facilities, and
the cancellation or termination of all letters of credit issued under the Senior
Credit Facilities, in the event that (x) ANTEC, Newco or any of their
Affiliates, or any of their successors and assigns, enter into and consummate an
agreement to Transfer all or any portion of their Interests, or the Company
Transfers all or substantially all of its assets, in each case to one or more
persons other than Newco or any of its subsidiaries, (y) there is any
foreclosure on any of the Interests held by ANTEC or Newco (or any of their
successors or assigns) or a Transfer in lieu of foreclosure or an exercise of
any rights

                                       30

or remedies of a secured creditor with respect to such Interests, in each case
pursuant to the Senior Credit Facilities or otherwise, or (z) during the
continuance of an Event of Default, then upon either (I) written notice by the
Class B Member to the Company and Newco in the event of the circumstances
described in clause (y), (II) written notice by the Administrative Agent to the
Class B Member, the Company and Newco in the event of the circumstances
described in clause (y) or clause (z), or (III) simultaneously in the event of
the circumstances described in clause (x), the Class B Interest automatically
shall be exchanged (at such time as may be specified in the notice or
immediately if no time is specified in the notice or no notice is required) for
such of the following as may be selected by the Class B Member by notice to the
Company:

                           (i)      Duly authorized, validly issued, fully paid
                  and non-assessable shares of Newco common stock with a Fair
                  Market Value as of the date of exchange equal to the
                  unredeemed portion of Initial Class B Balance plus the unpaid
                  Class B Return accrued to the date of exchange,

                           (ii)     One hundred thousand (100,000) shares of
                  Newco Preferred Stock, constituting all of the authorized
                  shares of Newco Preferred Stock, all of which shares shall be
                  duly authorized, validly issued, fully paid and non-assessable
                  (provided, however, that the provisions of Section 6 of Annex
                  A to the Certificate of Designations, and any other provisions
                  thereof (including, without limitation, the designation of
                  Newco Preferred Stock) referencing convertibility of Newco
                  Preferred Stock shall be deleted from such Annex A and shall
                  not be part of the powers, designations, preferences and
                  rights of Newco Preferred Stock if the Class B Member so
                  elects, in writing),

                           (iii)    a subordinated note of Newco with a maturity
                  date six months after the final maturity of the Senior Credit
                  Facilities in the principal amount equal to the unredeemed
                  portion of the Initial Class B Balance plus the Class B Return
                  accrued to the date of exchange, in the form of, and
                  containing the terms set forth in, Exhibit 2 hereto (provided,
                  however, that the provisions of Section 3 of such Exhibit 2,
                  and any other provisions thereof (including, without
                  limitation, the title of such subordinated note) referencing
                  convertibility of such subordinated note, shall be deleted
                  from such Exhibit 2 and shall not be part of such subordinated
                  note if the Class B Member so elects in writing), or

                           (iv)     any combination of the foregoing yielding an
                  aggregate value consistent with the foregoing equal to the
                  unredeemed portion of the Initial Class B Balance plus the
                  Class B Return accrued to the date of exchange

(the securities or other instruments receivable by Class B Member in such
exchange, the "New Securities"); provided that:

                           (V)      if the Class B Member elects to receive a
                  combination of New Securities as described in clause (iv)
                  above, the amount of "Maximum Quarterly Redemption" referenced
                  in Section 4(a)(ii)(A) of Annex A to the Certificate of

                                       31
<PAGE>   36

                  Designations and the amount of "Maximum Quarterly Payment"
                  referenced in Section 1(a)(i) of the form of subordinated note
                  of Newco attached hereto as Exhibit 2 shall be reduced on a
                  pro rata basis to reflect the proportion allocated to each
                  such New Security of the unredeemed portion of the Class B
                  Unreturned Capital plus the Class B Return accrued to the date
                  of exchange that has not been paid or added to Class B
                  Unreturned Capital;

                           (W)      if the Class B Member shall not have given
                  notice of its selection prior to the effective time of an
                  exchange, then (1) it shall be presumed to have selected to
                  receive a subordinated note as provided in clause (iii) above
                  that does not contain the references to convertibility of such
                  subordinated note, and (2) such subordinated note may be
                  exchanged by the Class B Member (notwithstanding its having
                  ceased to be a Member of the Company), by written notice to
                  Newco given not later than twenty (20) days after the
                  effective time of the exchange pursuant to clause (W)(1) of
                  this proviso, for any of the other New Securities described in
                  clauses (i) through (iii) above or, subject to clause (iv)
                  above, any combination of the same;

                           (X)      the Class B Member, by notice to the
                  Company, may change its selection at any time prior to the
                  effective time of the exchange, and, in the event that the New
                  Securities can not be issued or are not promptly issued as a
                  result of inaction by Newco or otherwise, the Class B Member
                  shall be entitled to change its selection until the earlier of
                  when it receives the New Securities it selected and twenty
                  (20) days after such effective time (and for sixty (60) days
                  thereafter it may elect to add any convertibility provisions
                  contained in such New Securities);

                           (Y)      if the Class B Member selects to receive
                  either the Newco common stock pursuant to clause (i) above or
                  the Newco Preferred Stock pursuant to clause (ii) above, and
                  the exchange occurs, or by its terms should occur, prior to
                  completion of any filings or corporate formalities necessary
                  for the issuance of such common stock or Newco Preferred Stock
                  (such as, by way of example but not limitation, any necessary
                  increase in the number of shares of Newco common stock or
                  preferred stock authorized for issuance; approval by the Board
                  of Directors of Newco of the Certificate of Designations and
                  filing of the same with the office of the Secretary of State
                  of the State of Delaware; and approval of the issuance of such
                  common stock or Newco Preferred Stock (as applicable) by the
                  Board of Directors of Newco) and the actual issuance thereof,
                  then (1) as part of the exchange, Newco shall, and the Company
                  shall cause Newco to, deliver to the Class B Member a
                  subordinated note as provided in clause (iii) above that does
                  not contain references to convertibility of such subordinated
                  note, and (2) within ten (10) days after the exchange, the
                  Company shall cause Newco to complete such filings and
                  formalities and issue and deliver such common stock or Newco
                  Preferred Stock (as applicable) against return of the
                  subordinated note (provided that, prior to such issuance and
                  delivery, the Class B Member (notwithstanding its

                                       32
<PAGE>   37

                  having ceased to be a Member of the Company) shall be entitled
                  to exercise the rights set forth in clause (W)(2) above); and

                           (Z)      the Class B Member shall not be entitled to
                  select the mix of New Securities which would result in a
                  Change of Control of Newco or a "Change in Control" as defined
                  in the Senior Credit Agreement.

Promptly upon receipt of any notice from the Class B Members pursuant to clause
(I) above, the Company and Newco shall cause a copy thereof to be delivered to
the Administrative Agent. The Company and Newco shall give each Class B Member
written notice of the occurrence of any event described in clause (x) or (y)
above not later than five (5) business days after the occurrence of such event.

                  (b)      CESSATION OF CLASS B RIGHTS UPON MANDATORY EXCHANGE.
Upon the exchange of the Class B Interest for the New Securities as set forth
above in this Section 8.03, the Class B Interest shall be completely
extinguished (including, without limitation, any preference or other claim
relating thereto) and neither Nortel nor any transferee permitted pursuant to
Section 8.01 shall have any rights, claims, duties, liabilities or obligations
whatsoever with respect to the Company under the Class B Interest or otherwise
as a Member of the Company, and shall cease to be a Member for all purposes;
provided that, notwithstanding the foregoing, Nortel and each transferee
permitted pursuant to Section 8.01 shall remain entitled, after effectiveness of
such exchange, solely to exercise the rights of a Class B Member set forth in
clauses (W)(2), (X) and (Y) of the first sentence of Section 8.03(a).

                                   ARTICLE IX

                           DISSOLUTION AND LIQUIDATION

         9.01.    EVENTS CAUSING DISSOLUTION. The Company shall be dissolved and
its affairs wound up upon the earlier of:

                  (a)      Any transaction authorized by or subject to Section
18-209 of the Act as a result of which the Company is not the surviving entity;

                  (b)      The election to dissolve the Company made by the
holders of a majority of the Class A Interests and the Class B Member;

                  (c)      At any time there are no Members of the Company,
unless the business of the Company is continued pursuant to the Act; or

                  (d)      The entry of a decree of judicial dissolution under
Section 18-802 of the Act.

         9.02.    PROCEDURES ON DISSOLUTION. Dissolution of the Company shall be
effective on the day on which occurs the event giving rise to the dissolution,
but the Company shall not

                                       33
<PAGE>   38

terminate until the assets of the Company shall have been distributed as
provided herein and the Certificate shall have been canceled. Notwithstanding
the dissolution of the Company, prior to the termination of the Company, as
aforesaid, the business of the Company and the affairs of the Members, as such,
shall continue to be governed by this Agreement. The Managing Member or one or
more other Persons appointed as Liquidator by the Managing Member shall
liquidate the assets of the Company, apply and distribute the proceeds thereof
as contemplated by this Agreement and cause the cancellation of the Certificate.

         9.03.    DISTRIBUTIONS UPON LIQUIDATION.

                  (a)      Upon dissolution, the Company, by and through the
Liquidator, shall satisfy liabilities owing to creditors (including creating
such reserves as may be required by non-waivable provisions of Section 18-804(b)
of the Act or as the Liquidator otherwise deems reasonably necessary for any
contingent liabilities or obligations of the Company). Said reserves may be paid
over by the Liquidator to a bank, to be held in escrow for the purpose of
complying with any such provisions of Section 18-804(b) of the Act or paying any
such contingent liabilities or obligations and, at the expiration of such period
as may be required by non-waivable provisions of Section 18-804(b) of the Act or
as the Liquidator may deem advisable, such reserves shall be distributed to the
Members or their assigns in the manner set forth in Section 9.03(b).

                  (b)      After satisfying such liabilities (including the
creation of reserves) as set forth in Section 9.03(a), the Liquidator shall
cause the remaining net assets of the Company to be distributed: first, to the
Members to the extent of any unpaid principal of and interest on any Member
Loans; second, subject to Section 8.02(b), to the Class B Member to the extent
of the Class B Unreturned Capital and Class B Return; and then to the Members
pro rata in proportion to the positive balances in their respective Capital
Accounts (after such Capital Accounts have been adjusted to reflect any Net
Profit or Net Loss or any items of income, gain, loss or deduction to be
allocated to the Members through the time of the dissolution and liquidation of
the Company pursuant to Article V hereof and the distributions made pursuant to
the previous clauses of this sentence). Distributions pursuant to this Section
9.03(b) shall be made by the end of the Fiscal Year during which the dissolution
of the Company occurs (or, if later, within ninety (90) days of such
dissolution). In the event that any part of such net assets consists of notes or
accounts receivable or other noncash assets, the Liquidator may take whatever
steps it deems appropriate to convert such assets into cash or into any other
form which would facilitate the distribution thereof. If any assets of the
Company are to be distributed in kind, such assets shall be distributed on the
basis of their fair market value net of any liabilities; provided, however,
that, unless Class B Members holding a majority of the Class B Interests
otherwise consent in writing prior to such distribution, all distributions to
the Class B Members pursuant to this Section 9.03(b) shall be made solely in
cash.

                SERIES A CONVERTIBLE SUBORDINATED PREFERRED STOCK

         Section 1. Designation and Rank. A total of one hundred thousand
(100,000) shares of Preferred Stock of the Corporation are hereby designated as
Series A Convertible Subordinated Preferred Stock. All shares of Series A
Convertible Subordinated Preferred Stock shall rank equally and be identical in
all respects. The Corporation shall not be restricted from issuing additional
securities of any kind, including shares of Preferred Stock of any class, series
or designation (including, without limitation, Preferred Stock ranking senior to
or in parity with, as to rights and preferences, the Series A Convertible
Subordinated Preferred Stock). The Series A Convertible Subordinated Preferred
Stock shall, with respect to rights upon liquidation, dissolution or winding up
of the affairs of the Corporation, rank senior and prior to the Corporation's
common stock, par value $0.01 per share (the "Common Stock").

         Section 2. Dividends. The Series A Convertible Subordinated Preferred
Stock shall accrue dividends commencing on the date of issuance at the rate of
ten percent per annum based upon the Liquidation Preference thereof. Such
dividends shall not be paid currently, but shall be added annually on the first
day of each calendar to the Liquidation Preference.

         Section 3. Voting Rights. Except as otherwise specifically required by
applicable law, the holders of Series A Convertible Subordinated Preferred Stock
shall not be entitled to vote or give a consent to or on any matters required or
permitted to be submitted to the shareholders of the Corporation for their
approval. Notwithstanding the foregoing, for so long as any shares of Series A
Convertible Subordinated Preferred Stock remain outstanding, the Corporation
shall not, without the prior written consent of holders of at least two-thirds
(2/3) of the then outstanding shares of Series A Convertible Subordinated
Preferred Stock, declare, pay or set aside any dividends on shares of Common
Stock (other than dividends payable in shares of Common Stock).

         Section 4. Redemption. (a) General. Subject to Sections 4(b) and 4(i)
hereof, shares of the Series A Convertible Subordinated Preferred Stock shall be
redeemable by the Corporation as follows:

                  (i)      Optional Redemption. The Corporation may, at any time
and from time to time at the option of the Corporation, redeem shares of Series
A Convertible Subordinated Preferred Stock, in whole or in part, in the sole
discretion of the Board of Directors, to the extent it has funds legally
available therefor, at the redemption price of 100% of the Liquidation
Preference thereof plus accrued dividends with respect thereto that have not
previously been added to the Liquidation Preference.

                  (ii)     Mandatory Redemption. The Corporation shall redeem
the Series A Convertible Subordinated Preferred Stock at the redemption price of
100% of the Liquidation Preference thereof plus accrued dividends with respect
thereto that have not previously been

<PAGE>   47

added to the Liquidation Preference, as follows:

                           (A)      in quarterly installments, commencing on the
         first business day after the six-month anniversary of the Closing Date
         and thereafter on each successive three-month anniversary thereof, in
         the maximum aggregate amount permitted under Section 4(b) up to (and
         including) $[33,000,000] per such installment (the "Maximum Quarterly
         Redemption"), until all outstanding shares of Series A Convertible
         Subordinated Preferred Stock are redeemed in full (as defined below);
         and

                           (B)      in any event, in full (as defined below), at
         the earlier of (1) the date occurring six (6) months after the
         Revolving Loan Commitment Termination Date, (2) a Change of Control of
         the Corporation, (3) Bankruptcy and (4) acceleration of the Senior
         Credit Facilities in accordance with the terms thereof.

For the purposes hereof, the shares of Series A Convertible Subordinated
Preferred Stock shall be redeemed in full at such time as the holders have
received cash redemption payments equal, in the aggregate, to the sum of 100% of
the Liquidation Preference thereof plus accrued dividends with respect thereto
that have not previously been added to the Liquidation Preference. Redemption
payments shall be applied first, to accrued dividends that previously have not
been added to the Liquidation Preference, and second, to the Liquidation
Preference.

         (b)      Certain Limitations. Until payment in full in cash of all
Senior Debt, the termination of any commitments to lend under the Senior Credit
Facilities and the cancellation or termination of any letters of credit issued
under the Senior Credit Facilities, no obligations to make redemption payments
shall arise, and no redemption payment shall be made, pursuant to Section
4(a)(ii)(A), and no redemption payment shall be made pursuant to Section 4(a)(i)
or Section 4(a)(ii)(B), unless and until:

                  (1)      prior to the date on which such redemption is made,
         the Borrowers have delivered to the Administrative Agent all financial
         statements, compliance certificates and other documents required to be
         delivered in connection with the most recent fiscal quarter ending
         prior to such date pursuant to the Senior Credit Agreement,

                  (2)      both immediately before and after giving pro forma
         effect to such redemption, no Event of Default shall have occurred and
         be continuing,

                  (3)      after giving pro forma effect to such redemption, the
         Borrowers shall have Excess Availability of at least $75 million, and

                  (4)      the Borrowers shall have delivered an officer's
         certificate of ANTEC signed by the chief financial officer of ANTEC
         certifying as to the foregoing clauses (1)-(3) and attaching a
         Borrowing Base Certificate demonstrating such Excess Availability, in
         each case in form and substance satisfactory to Administrative Agent
         under the Senior Credit Agreement;

<PAGE>   48

         provided that, with respect to the fourth fiscal quarter of any fiscal
         year, Borrowers shall be deemed to have satisfied the part of the
         condition contained in clause (1) above requiring delivery of audited
         financial statements upon delivery of unaudited financial statements
         for such fiscal year in lieu of audited financial statements for such
         fiscal year and a certificate signed by the chief financial officer of
         ANTEC certifying that, when delivered, the audited financial statements
         shall not contain any material differences from the unaudited financial
         statements.

         (c)      Corporation Covenant. So as to enable the exercise of the
redemption rights of the holders of shares of Series A Convertible Preferred
Stock in this Section 4, the Corporation shall, and shall cause its subsidiaries
to, comply with all reporting requirements and document delivery requirements
contained in the Senior Credit Facilities, make all requisite certifications
under the Senior Credit Facilities, and take all such further actions as may be
reasonably requested by the holders of shares of Series A Convertible Preferred
Stock to enable the Corporation, to the fullest extent possible, to make all
redemption payments contemplated by Section 4(a)(ii) timely and in full
(provided, however, that in no event shall the Corporation be required by any of
the foregoing provisions of this Section 4(c) to take any action prohibited by
the terms of the Senior Credit Facilities). The Corporation shall notify the
holders in writing of any Default or Event of Default or any material breach by
the Corporation of this Section 4(c), in each case not later than five (5)
business days after occurrence thereof.

         (d)      Payment of Redemption Price. The amount of the redemption
price on any shares of Series A Convertible Subordinated Preferred Stock
redeemed, on any redemption provided for herein, shall be paid in cash.

         (e)      Defined Terms. Capitalized terms used herein and not defined
herein shall have the meanings specified in the Second Amended and Restated
Limited Liability Operating Agreement of Arris Interactive L.L.C. dated as of
August 3, 2001, regardless of any subsequent amendment, modification or
termination thereof (the "LLC Agreement").

         (f)      Notice. Not less than fifteen (15) days nor more than
forty-five (45) days (such date as fixed by the Board of Directors is referred
to herein as the "Redemption Record Date") prior to the date fixed for any
mandatory or optional redemption of shares of the Series A Convertible
Subordinated Preferred Stock pursuant to this Section 4 (each such date, a
"Redemption Date"), a notice specifying the time and place of the redemption and
the number of shares to be redeemed shall be given by registered or certified
mail (return receipt requested) to the holders of record on the Redemption
Record Date of the shares of the Series A Convertible Subordinated Preferred
Stock to be redeemed at their respective addresses as the same shall appear on
the books of the Corporation, calling upon each holder of record to surrender to
the Corporation on the Redemption Date at the place designated in the notice
such holder's certificate or certificates representing the number of shares
specified in the notice of redemption. Neither failure to mail such notice, nor
any defect therein or in the mailing thereof, to any particular holder shall
affect the sufficiency of the notice or the validity of the proceedings for
redemption with respect to the other holders. Any notice mailed in the manner
herein provided shall be conclusively presumed to have been duly given effective
three (3) business days after the

<PAGE>   49

date of mailing, whether or not the holder receives the notice. On or after the
Redemption Date, each holder of shares of Series A Convertible Subordinated
Preferred Stock to be redeemed shall present and surrender such holder's
certificate or certificates for such shares to the Corporation at the place
designated in the redemption notice and thereupon, subject to Sections 4(b) and
4(i), the redemption price of the shares, and any unpaid dividends thereon to
the Redemption Date, shall be paid to or on the order of the person whose name
appears on such certificate or certificates as the owner thereof, and each
surrendered certificate shall be canceled. In case fewer than all the shares
represented by any such certificate are redeemed, a new certificate shall be
issued representing the unredeemed shares.

         (g)      Termination of Rights. If a notice of redemption has been
given pursuant to this Section 4 and if, on or before the Redemption Date, the
funds necessary for such redemption shall have been set aside by the
Corporation, separate and apart from its other funds, in trust for the pro rata
benefit of the holders of the shares of Series A Convertible Subordinated
Preferred Stock so called for redemption, then, notwithstanding that any
certificates for such shares of Series A Convertible Subordinated Preferred
Stock have not been surrendered for cancellation, on the Redemption Date the
holders of such shares shall cease to be stockholders with respect to those
shares, shall have no interest in or claims against the Corporation by virtue
thereof, except, subject to Sections 4(b) and 4(i), the right to receive the
monies payable upon such redemption, without interest thereon, upon surrender
(and endorsement, if required by the Corporation) of their certificates, and the
shares of Series A Convertible Subordinated Preferred Stock evidenced thereby
shall no longer be outstanding. Subject to applicable escheat laws, any monies
so set aside by the Corporation and unclaimed at the end of one year from the
Redemption Date shall revert to the general funds of the Corporation, after
which reversion, subject to Sections 4(b) and 4(i), the holders of such shares
so called for redemption shall look only to the general funds of the Corporation
for the payment of the redemption price, without interest. Any interest accrued
on funds so deposited shall belong to the Corporation and be paid thereto from
time to time. Notwithstanding the foregoing, the Corporation will not set aside
funds for a redemption unless and until permitted by Sections 4(b) and 4(i).

         (h)      Selection of Shares. In every case of redemption of fewer than
all of the outstanding shares of the Series A Convertible Subordinated Preferred
Stock pursuant to this Section 4, the shares to be redeemed shall be selected
pro rata.

         (i)      Subordination. The obligations under the terms of the Series A
Convertible Subordinated Preferred Stock and all amounts payable thereunder are
subordinated to the extent and in the manner provided in the Subordination
Agreement dated as of August 3, 2001, among Nortel Networks, LLC, The CIT
Group/Business Credit, Inc., as Administrative Agent, the Corporation and Arris
Interactive L.L.C., as such Subordination Agreement may be amended, restated,
amended and restated, supplemented or otherwise modified from time to time (the
"Subordination Agreement"). Each of this Section 4(i) and the Subordination
Agreement shall constitute a continuing offer to all persons who, in reliance
upon such provisions, become holders of, or continue to hold Senior Debt (as
defined in the Subordination Agreement), and such provisions are made for the
benefit of such holders, and such holders are made obligees hereunder and any
one or more of them may enforce such provisions. Nothing in this Section

<PAGE>   50

4(i) shall be construed as limiting the obligations of the Corporation to the
holders of the shares of Series A Convertible Subordinated Preferred Stock,
which, as between the Corporation and the holder of the shares, are
unconditional and absolute. Any certificate evidencing the Series A Convertible
Preferred Stock shall contain such legends as are required by the Subordination
Agreement.

         Section 5. Liquidation. The Series A Convertible Subordinated Preferred
Stock shall be preferred upon liquidation over the Common Stock and any other
class or classes of stock of the Corporation which by its terms expressly
provides that it ranks junior in rights and preferences to the Series A
Convertible Subordinated Preferred Stock upon liquidation, so that, subject to
Sections 4(b) and 4(i), holders of shares of Series A Convertible Subordinated
Preferred Stock shall be entitled to be paid, after full payment is made on any
stock ranking prior to the Series A Convertible Subordinated Preferred Stock as
to rights and preferences, but before any distribution is made to the holders of
the Common Stock and such junior stock upon the voluntary or involuntary
dissolution, liquidation or winding up of the Corporation. Subject to Sections
4(b) and 4(i), the amount payable on each share of Series A Convertible
Subordinated Preferred Stock in the event of the voluntary or involuntary
dissolution, liquidation or winding up of the Corporation shall be equal to the
Class B Unreturned Capital and the Class B Return, as of the date of issuance,
less any amount exchanged for common stock as provided in Section 8.03(a)(i) of
the LLC Agreement or a subordinated note as provided for in Section 8.03(a)(iii)
of the LLC Agreement or not exchanged, divided pro rata among the number of
outstanding Series A Convertible Preferred Shares on that date plus accrued
dividends with respect thereto (the "Liquidation Preference"). Subject to
Sections 4(b) and 4(i), if, upon any such liquidation, dissolution or winding up
of the Corporation, its net assets are insufficient to permit the payment in
full of the amounts to which the holders of all outstanding shares of Series A
Convertible Subordinated Preferred Stock are entitled as above provided, the
entire net assets of the Corporation remaining (after full payment is made on
any classes or series of stock ranking prior to the Series A Convertible
Subordinated Preferred Stock) shall be distributed among the holders of shares
of Series A Convertible Subordinated Preferred Stock in amounts proportionate to
the full preferential amounts to which they and holders of shares of Preferred
Stock ranking in parity with the Series A Convertible Subordinated Preferred
Stock are entitled. After such payment shall have been made in full to the
holders of the Series A Convertible Subordinated Preferred Stock, the holders of
the outstanding Series A Convertible Subordinated Preferred Stock shall be
entitled to no further participation in such distribution of the assets of the
Corporation and the remaining assets of the Corporation shall be divided and
distributed among the holders of the other classes of stock then outstanding
according to their respective rights and shares. For the purpose of this Section
4, the voluntary sale, lease, exchange or transfer, for cash, shares of stock,
securities or other consideration, of all or substantially all the Corporation's
property or assets to, or its consolidation or merger with, one or more
corporations shall not be deemed to be a liquidation, dissolution or winding up
of the Corporation, voluntary or involuntary.

         Section 6. Conversion Provisions.

         (a)      Conversion Right. Unless previously redeemed as provided in
Section 4 hereof, shares of the Series A Convertible Subordinated Preferred
Stock may be converted prior to

<PAGE>   51

redemption thereof at such time, in such manner and upon such terms and
conditions as hereinafter provided in this Section 6 into duly authorized,
validly issued, fully paid and non-assessable full shares of Common Stock. In
the event the Corporation shall call for redemption the shares of Series A
Convertible Subordinated Preferred Stock pursuant to Section 4 hereof, the
conversion right provided by this Section 6 shall terminate immediately upon the
setting aside by the Corporation, in the manner described in Section 4(g) above,
of funds sufficient for such redemption, but shall be reinstated in the event
that the Corporation fails to fulfill its redemption obligations on the relevant
Redemption Date. Subject to Sections 4(b) and 4(i), in case cash, securities or
property other than Common Stock shall be payable, deliverable or issuable upon
conversion as provided herein, then all references to Common Stock in this
Section 6 shall be deemed to apply, so far as appropriate and as nearly as may
be, to such cash, property or other securities.

         (b)      Conversion Date. Unless previously redeemed as provided in
Section 4 hereof and subject to Section 6(a), the Series A Convertible
Subordinated Preferred Stock shall be convertible at any time and from time to
time at the option of the holder(s) thereof.

         (c)      Conversion Price. Holders of shares of Series A Convertible
Subordinated Preferred Stock may convert shares of Series A Convertible
Subordinated Preferred Stock into a number of shares of Common Stock calculated
by dividing, for each share of Series A Convertible Subordinated Preferred Stock
to be converted, (1) the Liquidation Preference plus accrued dividends with
respect thereto that have not previously been added to the Liquidation
Preference by (2) the Fair Market Value per share of Common Stock (this price as
from time to time adjusted cumulatively pursuant to the provisions of this
Section 6 is hereinafter referred to as the "Conversion Price") as of the date
of conversion. "Fair Market Value" shall mean, with respect to the Common Stock
of the Corporation, the average closing price per share of Common Stock on The
Nasdaq Stock Market (or, if the Common Stock is not then trading thereon, such
other nationally recognized stock market or exchange, if any, on which the
Common Stock may then be actively traded) for the twenty (20) consecutive
trading days ending two (2) days prior to the date of determination. In the
absence of such trading markets, the Fair Market Value shall be as reasonably
determined by the board of directors of the Corporation based upon the written
valuation of an independent valuation firm of national reputation.

         (d)      Reclassification, Consolidation or Merger. In the case of (A)
any capital reorganization, reclassification or other change of outstanding
Common Stock (other than a change in par value), or (B) any consolidation of the
Corporation with any other corporation or any merger of the Corporation into
another corporation or of another corporation into the Corporation (other than a
consolidation or merger in which the Corporation is the continuing or surviving
corporation and which does not result in any reclassification of, or change
(other than a change in par value) in, the outstanding Common Stock or (C) any
sale or transfer to another corporation or entity (other than by mortgage or
pledge) of all or substantially all of the properties and assets of the
Corporation, the Corporation (or its successor in such consolidation or merger)
or the purchaser of such properties and assets shall make appropriate provision
so that the holder of each share of Series A Convertible Subordinated Preferred
Stock then outstanding shall have the right thereafter to convert such share
into the kind and amount of shares of stock or

<PAGE>   52

other securities and property receivable upon such reclassification, change,
consolidation, merger, sale or transfer by a holder of the number of shares of
Common Stock into which such Series A Convertible Subordinated Preferred Stock
might have been converted immediately prior to such reclassification, change,
consolidation, merger, sale or transfer, and the holders of the Series A
Convertible Subordinated Preferred Stock shall have no other conversion rights
under these provisions; provided, that effective provision shall be made, in the
Articles or Certificate of Incorporation of the resulting or surviving
corporation or otherwise or in any contracts of sale or transfer, so that the
provisions set forth herein for the protection of the conversion rights of
Series A Convertible Subordinated Preferred Stock shall thereafter be made
applicable, as nearly as reasonably may be, to any such other shares of stock or
other securities and property deliverable upon conversion of the Series A
Preferred Stock remaining outstanding or other convertible preferred stock or
other securities received by the holders of Series A Convertible Subordinated
Preferred Stock in place thereof; and, provided further, that any such resulting
or surviving corporation or purchaser shall expressly assume the obligation to
deliver, upon the exercise of the conversion privilege, such shares, securities
or property as the holders of the Series A Preferred Stock remaining
outstanding, or other convertible preferred stock or other securities received
by the holders in place thereof, shall be entitled to receive pursuant to the
provisions hereof, and to make provisions for the protection of the conversion
rights as above provided.

         (e)      Method of Conversion. For any holder of Series A Convertible
Subordinated Preferred Stock to convert the same into Common Stock, it shall
give not less than sixty-one (61) days prior written notice to the Corporation
that it elects to convert all or a part of shares of Series A Convertible
Preferred Stock held by it and, prior to the expiration of the notice period as
specified in the notice (but not less than sixty-one (61) days), surrender the
certificate or certificates for such shares of Series A Convertible Subordinated
Preferred Stock at the office of the Corporation or at the office of the
transfer agent for the Series A Convertible Subordinated Preferred Stock, which
certificate or certificates, if the Corporation shall so request, shall be duly
endorsed to the Corporation or in blank or accompanied by proper instruments of
transfer to the Corporation or in blank (such endorsements or instruments of
transfer to be in form reasonably satisfactory to the Corporation), and shall
state in writing therein the name or names in which it wishes the certificate or
certificates for Common Stock to be issued. The Corporation will as soon as
practicable after the expiration of the notice period issue and deliver at the
office of the Corporation or of said transfer agent to the person for whose
account such Series A Convertible Subordinated Preferred Stock was so
surrendered, or to its nominee(s) or, subject to compliance with applicable law,
transferee(s), a certificate or certificates for the number of full shares of
Common Stock to which it shall be entitled, together with cash in lieu of any
fraction of a share as hereinafter provided. If surrendered certificates for
Series A Convertible Subordinated Preferred Stock are converted only in part,
the Corporation will issue and deliver to the holder, or to its nominee(s),
without charge therefor, a new certificate or certificates representing the
aggregate of the unconverted shares of Series A Convertible Subordinated
Preferred Stock. Such conversion shall be deemed to have been made as of the
date that (i) the notice period expires and (ii) the holder thereof has paid or
otherwise provided for all taxes, if any, payable in respect of any transfer
involved in the issuance or delivery of any certificate for Common Stock in a
name other than that of such holder; and the person or persons entitled to
receive the Common

<PAGE>   53

Stock issuable upon conversion of such Series A Convertible Subordinated
Preferred Stock shall be treated for all purposes as the record holder or
holders of such Common Stock on such date.

         The issuance of certificates for shares of Common Stock upon conversion
of shares of Series A Convertible Subordinated Preferred Stock shall be made
without charge for any issue, stamp or other similar tax in respect of such
issuance; provided, however, if any such certificate is to be issued in a name
other than that of the holder of the share or shares of Series A Convertible
Subordinated Preferred Stock converted, the person or persons requesting the
issuance thereof shall pay to the Corporation the amount of any tax which may be
payable in respect of any transfer involved in such issuance or shall establish
to the reasonable satisfaction of the Corporation that such tax has been paid.

         The Corporation shall not be required to convert Series A Convertible
Subordinated Preferred Stock, and no surrender of Series A Convertible
Subordinated Preferred Stock shall be effective for that purpose, while the
stock transfer books of the Corporation are closed for any purpose; but the
surrender of Series A Convertible Subordinated Preferred Stock for conversion
during any period while such books are so closed shall become effective for
conversion immediately upon the reopening of such books, as if the conversion
had been made on the date such Series A Convertible Subordinated Preferred Stock
was surrendered.

         (f)      Corporate Actions. In order that the Corporation may issue
shares of Common Stock upon conversion of the Series A Convertible Subordinated
Preferred Stock, the Corporation will use reasonable efforts to comply with all
applicable Federal and state securities laws and will use reasonable efforts to
list such shares to be issued upon conversion on such securities exchange on
which the Common Stock is listed. Subject to Sections 4(b) and 4(i), the
Corporation will not, by amendment of its Certificate of Incorporation or
through any consolidation, merger, reorganization, transfer of assets,
dissolution, issuance or sale of securities or any other voluntary action, avoid
or seek to avoid the observance or performance of any of its obligations
hereunder.

         (g)      Status of Shares Converted. In the event that any holder of
Series A Convertible Subordinated Preferred Stock converts its Series A
Convertible Subordinated Preferred Stock to Common Stock pursuant to this
Section 6, the right to preferential liquidation rights with respect to such
converted stock pursuant to Section 5 hereof shall be immediately terminated.
All shares of Series A Convertible Subordinated Preferred Stock received by the
Corporation upon conversion thereof into Common Stock shall be retired and be
restored to the status of authorized and unissued shares of Preferred Stock, and
may be reissued as part of another series of the Preferred Stock of the
Corporation, but such shares shall not be reissued as Series A Convertible
Subordinated Preferred Stock.

         (h)      Fractions upon Conversion. The Corporation shall not be
required to issue fractional shares of Common Stock or script upon conversion of
the Series A Convertible Subordinated Preferred Stock. As to any final fraction
of a share of Common Stock which a holder of one or more shares of Series A
Convertible Subordinated Preferred Stock would otherwise be entitled to receive
upon conversion of such shares in the same transaction, the

<PAGE>   54

Corporation shall pay a cash adjustment in respect of such final fraction in an
amount equal to the same fraction of the market value of a full share of the
Common Stock. For purposes of this Section 6(h), the market value of a share of
the Common Stock shall be the closing price per share on the business day
immediately preceding the date of conversion.

         Section 7. Notices to Holders of Series A Convertible Subordinated
Preferred Stock. In the event:

                  (a)      that the Corporation shall authorize the issuance to
         all holders of Common Stock of rights or warrants to subscribe for or
         purchase capital stock of the Corporation or of any other subscription
         rights or warrants; or

                  (b)      that the Corporation shall authorize the distribution
         to all holders of Common Stock of evidences of its indebtedness or
         assets (including, without limitation, cash dividends or cash
         distributions payable out of consolidated earnings or earned surplus or
         dividends payable in Common Stock); or

                  (c)      of any consolidation or merger to which the
         Corporation is a party and for which approval of any stockholders of
         the Corporation is required, or of the conveyance or transfer of the
         properties and assets of the Corporation substantially as an entirety,
         or of any capital reorganization or reclassification or change of the
         Common Stock (other than a change in par value, or from par value to no
         par value, or from no par value to par value, or as a result of a
         subdivision or combination); or

                  (d)      of the voluntary or involuntary dissolution,
         liquidation or winding up of the Corporation; or

                  (e)      that the Corporation proposes to take any other
         action which would require an adjustment in the number of shares of
         Common Stock or other securities or assets issuable upon conversion of
         shares of Series A Convertible Subordinated Preferred Stock pursuant to
         Section 6;

then the Corporation shall cause to be given to each of the registered holders
of the Series A Convertible Subordinated Preferred Stock at its address
appearing on the register for the Series A Convertible Subordinated Preferred
Stock, at least twenty (20) calendar days prior to the applicable record date,
if any, hereinafter specified, or, if no such record date if specified, twenty
(20) calendar days prior to the taking of any action referred to in clauses (a)
through (e) above, by registered mail, postage prepaid, return receipt
requested, a written notice stating (i) the date as of which the holders of
record of Common Stock to be entitled to receive any such rights, warrants or
distribution are to be determined, or (ii) the date on which any such
consolidation, merger, conveyance, transfer, dissolution, liquidation or winding
up is expected to become effective or (iii) the date on which such other action
is to be effected, and the date as of which it is expected that holders of
record of Common Stock shall be entitled to exchange their shares for securities
or other property, if any, deliverable upon such reclassification,
consolidation, merger, conveyance, transfer, dissolution, liquidation or winding
up or other action.

<PAGE>   55

         Section 8. No Impairment. The Corporation will not, by amendment of its
Certificate of Incorporation or through any consolidation, merger,
reorganization, transfer of assets, dissolution, issuance or sale of securities
or any other voluntary action, avoid or seek to avoid the observance or
performance of any of its obligations hereunder, but, subject to Sections 4(b)
and 4(i), will at all times in good faith assist in the carrying out of the all
the provisions hereof and in the taking of all such actions as may be necessary
or appropriate to protect the rights of holders of Series A Convertible
Redeemable Preferred Stock granted herein against impairment.

         Section 9. Transfer. Shares of Series A Convertible Subordinated
Preferred Stock shall be transferable only in compliance with applicable law,
including federal and state securities laws, and the delivery to the
Administrative Agent (and receipt of a written acknowledgment for such delivery)
of an instrument executed by or on behalf of the transferee to the effect that
the transferee agrees, upon acquisition of such shares by the transferee, that
it shall be bound by all of the terms and provisions of the Subordination
Agreement. Any attempt to transfer in violation of the foregoing shall be void
ab initio.

         Section 3. CONVERSION.

                  (a)      At any time after the Issue Date and while this Note
is outstanding, upon not less than sixty-one (61) days prior written notice to
the Company, the Holder may convert all or any portion of the principal amount
of this Note outstanding, and all or any portion of accrued and unpaid interest
on this Note, into such number of whole shares of Common Stock of the Company

share of Common Stock on The Nasdaq Stock Market (or, if the Common Stock is not
then trading thereon, such other nationally recognized stock market or exchange,
if any, on which the Common Stock may then be actively traded) for the twenty
(20) consecutive trading days ending two (2) days prior to the date of
determination. In the absence of such trading markets, the Fair Market Value
shall be as reasonably determined by the board of directors of the Company based
upon a written valuation prepared by an independent valuation firm of national
reputation.

                  (b)      Conversion of this Note shall be made upon surrender
of this Note to the Company at its principal place of business (or at such other
office as the Company shall designate by notice in writing to the Holder from
time to time), accompanied by written notice of the Holder's election to
convert. The Company agrees that, at the time of surrender and exercise of
conversion rights in compliance with the provisions hereof, the shares of Common
Stock issuable pursuant to such exercise shall be and be deemed to be issued to
the Holder (or, subject to compliance with applicable law, the Holder's
permitted designee or designees which may include the Holder for which the
Holder is acting as agent hereunder) as the record owner of such shares as of
the close of business of the Company on the date on which conversion rights
under this Note shall have been exercised as aforesaid, and that all such shares
shall be duly authorized, validly issued, fully paid and non-assessable.

                  (c)      Upon conversion of this Note in full, the Company
shall be forever released from all its obligations and liabilities under this
Note. Upon any conversion of this Note in part, the conversion of such converted
portion shall be recorded by Holder and endorsed by the Holder and the Company,
and the Company shall be forever released from all obligations and liabilities
under this Note with respect to such converted portion of this Note.
Notwithstanding Section 1(d), payments in respect of this Note shall not be made
in cash or wire transfer to the extent of any amount payable under this Note
that has been converted to Common Stock pursuant to this Section 3.

                  (d)      The issuance of certificates for shares of Common
Stock upon conversion of this Note shall be made without charge for any issue,
stamp or similar tax in respect of such issuance; provided, however, if any such
certificate is to be issued in a name other than that of the Holder, the person
or persons requesting the issuance thereof shall pay to the Company the

<PAGE>   59

amount of any tax which may be payable in respect of any transfer involved in
such issuance or shall establish to the reasonable satisfaction of the Company
that such tax has been paid.

                  (e)      In order that the Company may issue shares of Common
Stock upon conversion of the Note, the Company will use reasonable best efforts
to comply with all applicable federal and state securities laws and will use
reasonable best efforts to list such shares to be issued upon conversion on such
securities exchange on which the Common Stock is listed.

hereof may not be amended.

or any course of dealing shall operate as a waiver thereof; nor shall any single
or partial exercise of any right, remedy, power or privilege hereunder preclude
any other or further exercise thereof or the exercise of any other right,
remedy, power or privilege. The rights, remedies, powers and privileges herein
provided to the Holder are cumulative and not exclusive of any rights, remedies,
