ITEM 1.           SECURITY AND ISSUER.

                  This statement relates to Common Stock, par value $.01 per
share ("Common Stock"), of Net2000 Communications, Inc. (the "Issuer"). The
principal executive offices of the Issuer are located at 2180 Fox Mill Road,
Herndon, Virginia 20171.

ITEM 2.           IDENTITY AND BACKGROUND.

                  This statement is being filed by Blue Water Strategic Fund I,
L.L.C. ("Blue Water Strategic Fund"), a limited liability company organized
under the laws of the State of Delaware engaged in investments in private
companies, and Blue Water Capital, L.L.C. ("Blue Water Capital"), a limited
liability company organized under the laws of the State of Delaware which is
the Managing Member of Blue Water Strategic Fund. (Blue Water Strategic Fund
and Blue Water Capital are collectively referred to as the "Reporting
Persons"). Michael H. Acheson, Henry D. Barratt, Jr., Kim D. Cooke, and Reid R.
Miles are each managing Directors of Blue Water Capital (collectively Messrs.
Acheson, Barratt, Cooke and Miles are the "Managing Directors"). The principal
business address and the principal office address of each of the Reporting
Persons and Messrs. Barratt, Cooke and Miles is 8300 Greensboro Drive, Suite
1210, McLean, Virginia 22102. The principal business address and the principal
office address of Mr. Acheson is 260 East Brown Street, Suite 310, Birmingham,
Michigan 48009. The Reporting Persons and Managing Directors have not been (i)
convicted in a criminal proceeding (excluding traffic violations or similar
misdemeanors) during the last five years, or (ii) a party, during the last five
years, to a civil proceeding of a judicial or administrative body of competent
jurisdiction which resulted in either of them being subject to a judgment,
decree or final order enjoining future violations of, or prohibiting or
mandating activities subject to, federal or state securities laws or finding
any violation with respect to such laws.

ITEM 3.           SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

                  Blue Water Strategic Fund acquired directly from the Issuer,
on October 31, 1997, 437,956 shares of the Series A Preferred Stock, par value
$0.01 per share, of the Issuer (the "Series A Preferred Stock") and on May 19,
1998, 486,224 shares of Series B Preferred Stock, par value $0.01 per share
(the "Series B Preferred Stock"). Pursuant to the terms of the Series A
Preferred Stock and Series B Preferred Stock, such shares were converted into
an aggregate of 2,797,560 shares of Common Stock on March 7, 2000 at the
closing of the Issuer's initial public offering (the "IPO"). The funds used to
acquire the Series A Preferred Stock and Series B Preferred Stock, in the
aggregate amount of $1,500,000 and $1,500,001, respectively, were provided by
monies invested in Blue Water Strategic Fund by its members.

ITEM 4.           PURPOSE OF TRANSACTION.

                  Blue Water Strategic Fund purchased the Series A Preferred
Stock and Series B Preferred Stock for investment purposes. The Reporting
Persons currently intend to hold the Common Stock for investment, but may, at
some future time depending on market conditions and other factors, acquire
additional shares of Common Stock (through one or more market purchases or
purchases in private transactions) or dispose of all or a portion of the
securities which they now own or hereafter may acquire. Blue Water Strategic
Fund has agreed pursuant to a lock-up agreement that they will not offer,
pledge, sell, contract to sell, sell any option or contract to purchase,
purchase any option or contract to sell, grant any option, right or warrant to
convertible or exercisable or exchangeable for Common Stock, or enter into any
swap or similar agreement that transfers, in whole or in part, the economic
risk of ownership of the Common Stock during a period of 180 days from March 7,
2000 without the prior written consent of Goldman, Sachs & Co., the lead
underwriters of the IPO (the "Lock-Up Agreement"). Goldman, Sachs & Co. may,
however, in its sole discretion and at any time without notice, release all or
a portion of the securities subject to such Lock-Up agreement. A copy of the
Lock-Up Agreement is filed herewith and incorporated by reference. Pursuant to
a Second Amended and Restated Investor Rights Agreement entered into in
connection with the acquisition of the securities, Blue Water Strategic Fund
has been granted certain rights by the Issuer to have the Common Stock
registered for sale under the Securities Act of 1933, as amended (the "Investor
Rights Agreement").

                  The foregoing description of the Lock-Up Agreement does not
purport to be complete and is qualified in its entirety by the terms of the
Agreement which is filed as an exhibit to this statement and is incorporated by
reference herein.

                  Except as set forth above, the Reporting Persons have no
present plans or proposals which relate to or would result in any of the
actions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D.

ITEM 5.           INTEREST IN SECURITIES OF ISSUER.

                  The Series A Preferred Stock and Series B Preferred Stock
beneficially owned by the Reporting Persons automatically converted on March 7,
2000 into 2,797,560 shares of Common Stock. These shares represent
approximately 8.0% of the outstanding Common Stock of the Issuer as of March 7,
2000 (based on representations of the Issuer in its definitive prospectus dated
March 6, 2000). Blue Water Strategic Fund has the sole power to vote or direct
the vote, and sole power to dispose or to direct the disposition, of all such
securities. Such power is exercised through its Managing Member, Blue Water
Capital. The Reporting Persons and the Managing Directors have not effected any
other transactions in Common Stock during the past sixty days.

ITEM 6.           CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH
RESPECT TO SECURITIES OF THE ISSUER.

                  In connection with the purchase of the Series A Preferred
Stock and the Series B Preferred Stock, Blue Water Strategic Fund entered into
the Investor Rights Agreement. Blue Water Strategic Fund has the right to
demand registration of the shares of Common Stock, subject to certain
conditions and limitations. In addition, Blue Water Strategic Fund also has
been granted certain piggyback registration rights. The registration rights are
generally transferable in connection with any private sale of registerable
shares, including to any member of Blue Water Strategic Fund. The Issuer will
bear all expenses incident to its registration obligations upon exercise of
these demand and piggyback registration rights, except that it will not bear
any underwriting discounts or commissions, federal or state securities
registration fees or transfer taxes relating to the exercise of those rights.

                  Except as noted in this Schedule 13D, the Reporting Persons do
not have any other contracts, arrangements, understandings or relationships with
respect to the securities of the Issuer.

                  The foregoing description of the Investor Rights Agreement
does not purport to be complete and is qualified in its entirety by the terms of
the Agreement which is filed as an exhibit to this statement and is incorporated
by reference herein.

the Company will pay all Registration Expenses; provided that the Company
qualifies for the use of such form. Demand Registrations will be Short-Form
Registrations whenever the Company is permitted to use any applicable short
form. The Company will use its best efforts to make Short-Form Registrations
available for the sale of Series C Registrable Securities.

         (d)      REGISTRATION OF OTHER SECURITIES.

                  Whenever the Company shall effect a registration pursuant to
this Section 5.1 in connection with an offering by one or more holders of
Registrable Securities, no securities other than Registrable Securities shall
be included among the securities covered by such registration unless (i) in the
case of an underwritten offering, the managing underwriter of such offering
shall have advised such holders of such Registrable Securities in writing that
the inclusion of such other securities would not adversely affect such
offering, or (ii) such holders of such Registrable Securities shall have
consented in writing to the inclusion of such other securities. Any persons
other than holders of Registrable Securities who participate in Demand
Registrations which are not at the Company's expense will pay their share of
the Registration Expenses as provided in Section 5.7.

         (e)      RESTRICTIONS ON DEMAND REGISTRATIONS.

                  The Company shall not be obligated to effect any Demand
Registrations (i) within twelve (12) months after the effective date of a
previous Demand Registration or (ii) prior to one hundred eighty (180) days
after the time the Company makes an initial offering of Common Stock to the
public pursuant to an effective registration statement under the Securities
Act. The Company may delay the filing or effectiveness of any Demand
Registration statement for a period of not less than ninety (90) days and not
to exceed one hundred fifty (150) days after the date of a request for
registration pursuant to this Section 5.1 if (i) at the time of such request
the Company is engaged, or has fixed plans to engage within sixty (60) days of
the time of such request, in a firm commitment underwritten public offering of
Primary Shares in which the holders of Restricted Securities may include
Registrable Securities pursuant to Section 5.2 below, or (ii) the Company shall
furnish to the holders requesting registration pursuant to this Section 5.1 a
certificate signed by the President of the Company stating that, in the good
faith judgment of the Board of Directors of the Company, and with the
concurrence of the investment banker, if any, that is currently being retained
by the Company, it would be seriously detrimental to the Company and its
stockholders for such registration statement to be filed and it is therefore
essential to defer the filing of such registration statement (provided that the
Company may not utilize the deferral rights set forth in this Section 5.1(e)
more than once in any twelve (12) month period and in the event the Company
does utilize such right, the holders of the Restricted Securities requesting
such registration will be entitled to withdraw such request and, if such
request is withdrawn, such registration will not count as a

                                     - 17 -

registration pursuant to this Section 5.1 and the holders of the Restricted
Securities requesting such registration shall have no obligation to reimburse
the Company for the Company's expenses in connection with such rescinded
registration).

                  (i)      RESTRICTIONS ON LONG-FORM REGISTRATIONS.

                           In addition to the restrictions on Demand
Registrations set forth in Section 5.1(e), the Company shall not be obligated
to effect any Long-Form Registration under the Securities Act except in
accordance with the following provisions:

                           (A)     the Company shall not be obligated to file
(w) more than one (1) Long-Form Registration initiated pursuant to Section
5.1(b)(i) which becomes effective, (x) more than one (1) Long-Form Registration
initiated pursuant to Section 5.1(b)(ii) which becomes effective, (y) more than
one (1) Long-Form Registration initiated pursuant to Section 5.1(b)(iii) which
becomes effective or (z) any registration statement during any period in which
any other registration statement pursuant to which Primary Shares are to be or
were sold has been filed and not withdrawn or has been declared effective
within the prior one hundred eighty (180) days; and

                            (B)     the Company shall not be obligated to
effect any Long-Form Registration if the anticipated aggregate offering
proceeds with respect to the Registrable Securities included in such
registration statement, net of underwriting discounts and commissions, are
expected to be less than twenty million dollars ($20,000,000).

                  (ii)      RESTRICTIONS ON SHORT-FORM REGISTRATIONS.

                            In addition to the restrictions on Demand
Registrations set forth in Section 5.1(e), the Company shall not be obligated
to effect any Short-Form Registration under the Securities Act if the
anticipated aggregate offering proceeds with respect to the Registrable
Securities included in such registration statement, net of underwriting
discounts and commissions, are expected to be less than five million dollars
($5,000,000).

         (f)      OTHER REGISTRATION RIGHTS.

                  Except as provided in this Agreement, the Company will not
grant to any Persons the right to request the Company to register any equity
securities of the Company, or any securities convertible or exchangeable into
or exercisable for such securities, without the written consent of the holders
of a majority of the Series A Registrable Securities, Series B Registrable
Securities and Series C Registrable Securities, each voting separately as a
class; provided that the Company may grant rights to other Persons so long as
such rights are subordinate

                                     - 18 -

<PAGE>   19

to the rights of the holders of Registrable Securities, and the Company has
obtained the prior written consent of the holders a majority of the Registrable
Securities.

         (g)      EFFECTIVE REGISTRATION STATEMENT; RESCISSION.

                  A Demand Registration pursuant to this Section 5.1 shall not
be deemed to have been effected (i) unless a registration statement with
respect thereto has become effective, (ii) if after a registration statement
has become effective, such registration is interfered with by any stop order,
injunction or other order or requirement of the Commission or other
governmental agency or court for any reason, or (iii) if the conditions to
closing specified in the purchase agreement or underwriting agreement entered
into in connection with such registration are not satisfied, other than by
reason of some act or omission by the holders requesting such registration. A
requested Demand Registration under this Section 5.1 may be rescinded by
written notice to the Company by the holders requesting such registration;
provided, however, that such rescinded registration shall not count as a
registration statement initiated pursuant to this Section 5.1 for purposes of
Section 5.1(a) above if, notwithstanding Section 5.7 below, such holders
shall have reimbursed the Company for all out-of-pocket expenses incurred by
the Company in connection with such rescinded registration; provided, further,
however, that if at the time of such rescission, the holders requesting such
registration have learned of a material adverse change in the condition or
business of the Company not known to the holders requesting such registration
at the time of their request for such registration and have rescinded their
request for registration with reasonable promptness after learning of such
material adverse change, then the holders requesting such registration shall
not be required to pay any of such expenses.

         (h)      PRIORITY IN DEMAND REGISTRATIONS.

                  With respect to any registration pursuant to this Section
5.1, the Company may include in such registration any Primary Shares or Other
Shares; provided, however, that in the event the registration is for a
registered public offering involving an underwriting, if the underwriter (or
the managing underwriter on behalf of the underwriters) advises the Company
that the inclusion of all Registrable Securities, Primary Shares and Other
Shares proposed to be included in such registration would interfere with the
successful marketing (including pricing) of all such securities, then the
number of Registrable Securities, Primary Shares and Other Shares proposed to
be included in such registration shall be included in the following order:

                  (i)      first, Registrable Securities, pro rata;

                  (ii)     second, the Primary Shares; and

                  (iii)    third, the Other Shares.

<PAGE>   20

                  (i)      ADDITIONAL DEMAND REGISTRATION.

                           Notwithstanding any other provision of this Section
5.1, at any time or from time to time, if the Company effects the registration
of less than seventy percent (70%) of all of the Registrable Securities
requested to be registered pursuant to Section 5.1(a), the holders of a
majority of the Series A Registrable Securities, Series B Registrable
Securities and Series C Registrable Securities, as the case may be, shall be
entitled to request an additional registration pursuant to Section 5.1(a);
provided, however, that in no event shall the holders of a majority of the
Series A Registrable Securities, Series B Registrable Securities and Series C
Registrable Securities, as the case may be, be entitled to request more than
one such additional registration pursuant to this Section 5.1(i). Any such
registration shall be requested, effected and in all other respects in
accordance with the terms of Section 5.1(a), and the Company will pay all
Registration Expenses in connection with any such registration. This provision
shall apply successively in the event that any holder of Registrable Securities
shall continue to hold Registrable Securities solely as a result of Section
5.1(h).

         5.2.     PIGGYBACK REGISTRATION.

                  (a)      RIGHT TO PIGGYBACK.

                           If the Company at any time proposes to register any
of its securities under the Securities Act (other than registrations solely for
the registration of shares in connection with an employee benefit plan or a
merger or share exchange or consolidation and other than pursuant to Section
5.1, whether or not for sale for its own account, and the registration form to
be used may be used for the registration of Registrable Securities (a
"Piggyback Registration"), the Company will at each such time give prompt
written notice to all holders of Registrable Securities of its intention to do
so and of such holders' rights under this Section 5.2. Upon the written request
of any such holder made within thirty (30) days after the receipt of any such
notice (which request shall specify the Registrable Securities intended to be
disposed of by such holder), the Company will use its best efforts to effect
the registration under the Securities Act of all Registrable Securities which
the Company has been so requested to register by the holders thereof on the
same terms and conditions as the securities otherwise being sold in such
registration, to the extent requisite to permit the disposition of the
Registrable Securities so to be registered. No registration effected under this
Section 5.2 shall relieve the Company of its obligation to effect any
registration upon request under Section 5.1 above. The Company will pay all
Registration Expenses in connection with each registration of Registrable
Securities requested pursuant to this Section 5.2. The Company may withdraw or
postpone a Piggyback Registration made pursuant to this Section 5.2 without
obligation to the Investors.

                  (b)      PRIORITY IN PIGGYBACK REGISTRATIONS.

                           If (i) a registration pursuant to this Section 5.2
involves an underwritten offering of the securities so being registered,
whether or not for sale for the account of the Company, to be distributed (on a
firm commitment basis) by or through one or more underwriters of recognized
standing under underwriting terms appropriate for such a transaction, (ii) the
Registrable Securities so requested to be registered for sale for the account
of holders of Registrable Securities are not also to be included in such
underwritten offering (because the Company has not been requested so to include
such Registrable Securities pursuant to Section 5.4(b) and (iii) the
managing underwriter of such underwritten offering shall inform the Company in
writing of its belief that the number of securities requested to be included in
such registration exceeds the number which can be sold in (or during the time
of) such offering without adversely affecting the price to be received thereon,
then the Company will include in such registration, to the extent of the number
which the Company is so advised can be sold in (or during the time of) such
offering, first, all securities proposed by the Company to be sold for its own
account or all securities (other than Registrable Securities) proposed by the
Company to be sold for the account of the holders thereof, as the case may be,
second, such Registrable Securities requested to be included in such
registration pro rata on the basis of the number of shares of such Registrable
Securities so proposed to be sold and so requested to be included, and third,
other securities requested to be included in such registration.

                  (c)      OTHER REGISTRATIONS.

                           If the Company has previously filed a registration
statement with respect to Registrable Securities pursuant to Section 5.1 or
pursuant to this Section 5.2, and if such previous registration has not been
withdrawn or abandoned, the Company will not file or cause to be effected any
other registration of any of its equity securities or securities convertible or
exchangeable into or exercisable for its equity securities under the Securities
Act (except on Form S-4 or Form S-8 or any successor forms), whether on its own
behalf or at the request of any holder or holders of such securities, until a
period of at least three (3) months has elapsed from the effective date of such
previous registration.

         5.3.     REGISTRATION PROCEDURES.

                  If and whenever the Company is required to use its best
efforts to effect the registration of any Registrable Securities under the
Securities Act as provided in Sections 5.1 and 5.2, the Company will as
expeditiously as possible:

                  (i)      prepare and file with the Commission the requisite
registration statement to effect such registration and thereafter use its best
efforts to cause such registration statement to become and remain effective for
a period of one hundred

                                     - 21 -

eighty (180) days or until all of such Registrable Securities have been
disposed of (if earlier), provided that the Company may discontinue any
registration of its securities which are not Registrable Securities at any time

prospectus relating thereto or any amendments or supplements relating to such a
registration statement or prospectus, to one counsel selected by the holders of
a majority of Registrable Securities (the "Investor Counsel"), copies of a
registration statement, the prospectus and any amendments or supplements
thereto, and shall not file any thereof to which such counsel shall have
reasonably objected on the grounds that such registration statement,
prospectus, amendment or supplement does not comply in all material respects
with the requirements of the Securities Act or the rules or regulations
thereunder (it being understood that such five (5) business day period need not
apply to successive drafts of the same document proposed to be filed so long as
such successive drafts are supplied to such counsel in advance of the proposed
filing by a period of time that is customary and reasonable under the
circumstances);

                  (iii)    prepare and file with the Commission such amendments
and supplements to such registration statement and the prospectus used in
connection therewith as may be necessary to keep such registration statement
effective for a period of not less than six (6) months and to comply with the
provisions of the Securities Act with respect to the disposition of all
securities covered by such registration statement until such time as all of
such securities have been disposed of in accordance with the intended methods
of disposition by the seller or sellers thereof set forth in such registration
statement;

                  (iv)     notify in writing the Investor Counsel promptly of
the receipt by the Company of any notification with respect to (a) any comments
by the Commission with respect to such registration statement or prospectus or
any amendment or supplement thereto or any request by the Commission for the
amending or supplementing thereof or for additional information with respect
thereto, (b) the issuance by the Commission of any stop order suspending the
effectiveness of such registration statement or prospectus or any amendment or
supplement thereto or the initiation or threatening of any proceeding for that
purpose, and (c) the suspension of the qualification of such Registrable
Securities for sale in any jurisdiction or the initiation or threatening of any
proceeding for such purposes;

                  (v)      furnish to each seller of Registrable Securities
covered by such registration statement such number of conformed copies of such
registration statement and of each such amendment and supplement thereto (in
each case including all exhibits), such number of copies of the prospectus
contained in such

                                     - 22 -

registration statement (including each preliminary prospectus and any summary
prospectus) and any other prospectus filed under Rule 424 under the Securities
Act, in conformity with the requirements of the Securities Act, and such other
documents as such seller may reasonably request;

                  (vi)     use its best efforts to register or qualify all
Registrable Securities and other securities covered by such registration
statement under such other securities or blue sky laws of such United States
jurisdictions as each seller thereof shall reasonably request, to keep such
registration or qualification in effect for so long as such registration
statement remains in effect, and to take any other action which may be
reasonably necessary or advisable to enable such seller to consummate the
disposition in such jurisdictions of the securities owned by such seller,
except that the Company shall not for any such purpose be required to qualify
generally to do business as a foreign corporation in any jurisdiction wherein
it would not but for the requirements of this Section 5.3(vi) be obligated to
be so qualified, to subject itself to taxation in any such jurisdiction or to
consent to general service of process in any such jurisdiction;

                  (vii)    use its best efforts to cause all Registrable
Securities covered by such registration statement to be registered with or
approved by such other governmental agencies or authorities as may be necessary
by virtue of the business and operations of the Company to enable the seller or
sellers thereof to consummate the disposition of such Registrable Securities;

                  (viii)   furnish to each seller of Registrable Securities a
signed counterpart, addressed to such seller (and the underwriters, if any) of

                           (x)      an opinion of counsel for the Company dated
the effective date of such registration statement (and, if such registration
includes an underwritten public offering, dated the date of the closing under
the underwriting agreement), reasonably satisfactory in form and substance to
such seller, and

                           (y)      a "comfort" letter, dated the effective
date of such registration statement (and, if such registration includes an
underwritten public offering, dated the date of the closing under the
underwriting agreement), signed by the independent certified public accountants
who have certified the Company's financial statements included in such
registration statement, covering substantially the same matters with respect to
such registration statement (and the prospectus included therein) and, in the
case of the accountants' letter, with respect to events subsequent to the date
of such financial statements, as are customarily covered in opinions of
issuer's counsel and in accountants' letters delivered to the underwriters in
underwritten public offerings of securities and, in the case of the
accountants' letter, such other financial matters, and, in the case of the
legal opinion, such other legal matters, as such seller or such holder (or the
underwriters, if any) may reasonably request;

                                     - 23 -

<PAGE>   24

                  (ix)     notify each seller of Registrable Securities covered
by such registration statement, at any time when a prospectus relating thereto
is required to be delivered under the Securities Act, upon discovery that, or
upon the happening of any event of which the Company is aware as a result of
which, the prospectus included in such registration statement, as then in
effect, includes an untrue statement of a material fact or omits to state any
material fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances under which they were
made, and at the request of any such seller promptly prepare and furnish to
such seller a reasonable number of copies of a supplement to or an amendment of
such prospectus as may be necessary so that, as thereafter delivered to the
purchasers of such securities, 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 not misleading in
the light of the circumstances under which they were made;

                  (x)      make available for inspection by any seller of such
Registrable Securities, any underwriter participating in any disposition
pursuant to such registration statement and any attorney, accountant or other
agent retained by any such seller or underwriter (collectively, the
"Inspectors"), all pertinent financial and other records, pertinent corporate
documents and properties of the Company (collectively, the "Records"), as shall
be reasonably necessary to enable them to exercise their due diligence
responsibility, and cause the Company's officers, directors and employees to
supply all information (together with the Records, the "Information")
reasonably requested by any such Inspector in connection with such registration
statement. Any of the Information which the Company determines in good faith to
be confidential, and of which determination the Inspectors are so notified,
shall not be disclosed by the Inspectors unless (a) the disclosure of such
Information is necessary to avoid or correct a misstatement or omission in the
registration statement, (b) the release of such Information is ordered pursuant
to a subpoena or other order from a court of competent jurisdiction or (c) such
Information has been made generally available to the public. The seller of
Registrable Securities agrees that he, she or it will, upon learning that
disclosure of such Information is sought in a court of competent jurisdiction,
give notice to the Company and allow the Company, at the Company's expense, to
undertake appropriate action to prevent disclosure of the Information deemed
confidential;

                  (xi)     otherwise use its best efforts to comply with all
applicable rules and regulations of the Commission, and make available to its
security holders, as soon as reasonably practicable, an earnings statement
covering the period of at least twelve (12) months, but not more than eighteen
(18) months, beginning with the first full calendar month after the effective
date of such registration statement, which earnings statement shall satisfy the
provisions of the Securities Act;

                                     - 24 -

<PAGE>   25

                  (xii)    provide and cause to be maintained a transfer agent
and registrar for all Registrable Securities covered by such registration
statement from and after a date not later than the effective date of such
registration statement;

                  (xiii)   list such Registrable Securities on the national
securities exchange, or Nasdaq, on which any shares of the Common Stock are
listed or quoted or, if the Common Stock is not listed on a national securities
exchange or quoted on Nasdaq, use its best efforts to qualify such Registrable
Securities for inclusion on such national securities exchange or Nasdaq as the
holders of a majority of such Registrable Securities shall request;

                  (xiv)    issue to any underwriter to which any seller of
Registrable Securities may sell shares in such offering certificates evidencing
such Registrable Securities; and

                  (xv)     use its best efforts to take all other steps
necessary to effect the registration of such Registrable Securities
contemplated hereby.

The Company may require each seller of Registrable Securities as to which any
registration is being effected to furnish to the Company such information
regarding such seller and the distribution of such securities as the Company
may from time to time reasonably request in writing. In connection with the
preparation and filing of each registration statement under the Securities Act
pursuant to this Agreement, the Company will give the holder of Registrable
Securities registered under such registration statement a reasonable
opportunity to review and comment upon such registration statement, each
prospectus included therein or filed with the Commission, and each amendment
thereof or supplement thereto, all prior to finalization.

                  Each holder of Registrable Securities agrees by acquisition
of such Registrable Securities that upon receipt of any notice from the Company
of the happening of any event of the kind described in Section 5.3(ix), such
holder will forthwith discontinue such holder's disposition of Registrable
Securities pursuant to the registration statement relating to such Registrable
Securities until such holder's receipt of the copies of the supplemented or
amended prospectus contemplated by Section 5.3(ix) and, if so directed by the
Company, will deliver to the Company (at the Company's expense) all copies,
other than permanent file copies, then in such holder's possession of the
prospectus relating to such Registrable Securities current at the time of
receipt of such notice.

         5.4.     SELECTION OF UNDERWRITERS.

                  (a)      DEMAND REGISTRATIONS.

                           In connection with any Demand Registration by the
holders of Registrable Securities pursuant to Section 5.1(a), the Company
shall select the investment banker(s) and manager(s) that will administer the
offering (the "Underwriters") which such Underwriter shall be a first or second
tier underwriter and shall be subject to the approval by the holders of a
majority of the Registrable Securities to be included in such Demand
Registration (after consultation with each holder of Registrable Securities)
which shall not be unreasonably withheld. The Company will enter into an
underwriting agreement with such Underwriters for such offering, such agreement
to be reasonably satisfactory in substance and form to the holders of a
majority of the Registrable Securities to be included in such Demand
Registration, and the Underwriters and to contain such representations and
warranties by the Company and such other terms as are generally prevailing in
agreements of such type, including, without limitation, indemnities to the
effect and to the extent provided in Section 5.6. The Investor Counsel may, at
its option, participate in the negotiation of the underwriting agreement. The
holders of such Registrable Securities shall be a party to such underwriting
agreement and may, at their option, require that any or all of the
representations and warranties by, and the other agreements on the part of, the
Company to and for the benefit of such Underwriters shall also be made to and
for the benefit of the holders of such Registrable Securities and that any or
all of the conditions precedent to the obligations of such Underwriters under
such underwriting agreement be conditions precedent to the obligations of the
holders of such Registrable Securities. Any holder of such Registrable
Securities shall not be required to make any representations or warranties to
or agreements with the Company or the Underwriters other than representations,
warranties or agreements regarding such holder, such holder's Registrable
Securities and such holder's intended method of distribution and any other
representation required by Law.

                  (b)      PIGGYBACK REGISTRATIONS.

                           If the Company at any time proposes to register any
of its securities under the Securities Act as contemplated by Section 5.2 and
such securities are to be distributed by or through one or more underwriters,
the Company will, if requested by any holder of Registrable Securities as
provided in Section 5.2 and subject to the provisions of Section 5.2(b), use
its best efforts to arrange for such underwriters to include all the
Registrable Securities to be offered and sold by such holder among the
securities to be distributed by such underwriters. The holders of Registrable
Securities to be distributed by such underwriters shall be parties to the
underwriting agreement between the Company and such underwriters and may, at
their option, require that any or all of the representations and warranties by,
and the other agreements on the part of, the

                                     - 26 -

<PAGE>   27

Company to and for the benefit of such underwriters shall also be made to and
for the benefit of the holders of such Registrable Securities and that any or
all of the conditions precedent to the obligations of such underwriters under
such underwriting agreement be conditions precedent to the obligations of the
holders of such Registrable Securities, to the extent that such
representations, warranties, other agreements, and conditions precedent bear on
such holders' liability or otherwise impose obligations on such holders. Any
holder of such Registrable Securities shall not be required to make any
representations or warranties to or agreements with the Company or the
underwriters other than representations, warranties or agreements regarding
such holder, such holder's Registrable Securities and such holder's intended
method of distribution and any other representation required by law.

         (c)      HOLDBACK AGREEMENTS.

                  (i)      In connection with the initial public offering of
shares of Common Stock of the Company registered pursuant to the Securities Act
the holders of Registrable Securities shall not sell, make any short sale of,
grant any option for the purchase of, or otherwise dispose of any Restricted
Securities (other than those shares of Common Stock included in such
registration) without the prior written consent of the Company for a period
designated by the Company in writing to the holders of Registrable Securities,
which period shall begin not more than fourteen (14) days prior to the
effectiveness of the registration statement pursuant to which such public
offering shall be made and shall not last more than one hundred eighty (180)
days (or such other shorter period as the officers and directors of the Company
and holders of greater than ten percent (10%) of all Registrable Securities
mutually agree) after the effective date of such registration statement.

                  (ii)     The Company agrees (x) not to effect any public sale
or distribution of its equity securities or securities convertible into or
exchangeable or exercisable for any of such securities during the period
beginning (A) fourteen (14) days prior to, and ending (B) one hundred eighty
(180) days after, any underwritten Demand Registration pursuant to Section 5.1
has become effective or such shorter period as the Company and the managing
Underwriter otherwise agree, except as part of such underwritten registration
and except pursuant to registrations on Form S-4, S-8 or any successor or
similar forms thereto, and (y) to use commercially reasonable efforts to cause
the Common Stock Holders, the Investors, their respective permitted transferees
and each holder of at least five percent (5%) (on a fully-diluted basis) of its
equity securities or any securities convertible into or exchangeable or
exercisable for any such securities, in each case purchased from the Company at
any time after the date of this Agreement (other than in a public offering), to
agree not to effect any such public sale or distribution of such securities,
during such period, unless the managing Underwriter otherwise agrees to such
sale or distribution.

         5.5.     PREPARATION; REASONABLE INVESTIGATION.

                  In connection with the preparation and filing of each
registration statement under the Securities Act pursuant to this Agreement, the
Company will give the holders of Registrable Securities to be registered under
such registration statement, their underwriters, if any, and the Investor
Counsel and accountants, the opportunity to participate in the preparation of
such registration statement, each prospectus included therein or filed with the
Commission, and each amendment thereof or supplement thereto, and will give each
of them such access to its books and records and such opportunities to discuss
the business of the Company with its officers and the independent public
accountants who have certified its financial statements as shall be necessary,
in the opinion of such holder's and such underwriters' respective counsel, to
conduct a reasonable investigation within the meaning of the Securities Act.

         5.6.     INDEMNIFICATION.

                  (a)      INDEMNIFICATION BY THE COMPANY.

                           In the event of any registration of any securities
of the Company under the Securities Act, the Company will, and hereby does,
indemnify and hold harmless each holder of Registrable Securities selling such
Registrable Securities, its officers and directors, each underwriter, broker or
any other person acting on behalf of such seller and each other person, if any,
who controls any of the foregoing persons within the meaning of the Securities
Act against any losses, claims, damages or liabilities, joint or several, to
which such seller or any such director or officer or underwriter or controlling
person may become subject under the Securities Act or otherwise, insofar as
such losses, claims, damages or liabilities (or actions or proceedings, whether
commenced or threatened, in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
any registration statement under which such securities were registered under
the Securities Act, any preliminary prospectus, final prospectus or summary
prospectus contained therein, or any amendment or supplement thereto or any
document incident to registration or qualification of any Registrable
Securities, or arise out of or are based upon the omission or alleged omission
to state therein a material fact required to be stated therein or necessary to
make the statements therein not misleading or, with respect to any prospectus,
necessary to make the statements therein in light of the circumstances under
which they were made not misleading, or any violation by the Company of the
Securities Act or state securities or blue sky laws applicable to the Company
and relating to action or inaction required of the Company in connection with
such registration or qualification under such state securities or blue sky
laws; and the Company will reimburse such seller and each such director,
officer, underwriter and controlling person for any legal or any other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, liability, action or

                                     - 28 -

<PAGE>   29

proceeding; provided that the Company shall not be liable in any such case to
the extent that any such loss, claim, damage, liability (or action or
proceeding in respect thereof) or expense arises out of or is based upon an
untrue statement or alleged untrue statement or omission or alleged omission
made in such registration statement, any such preliminary prospectus, final
prospectus, summary prospectus, amendment or supplement in reliance upon and in
conformity with written information furnished to the Company through an
instrument duly executed by such seller, specifically stating that it is for
use in the preparation thereof and, provided further, that the Company shall
not be liable to any Person who participates as an underwriter in the offering
or sale of Registrable Securities or any other Person, if any, who controls
such underwriter within the meaning of the Securities Act, in any such case to
the extent that any such loss, claim, damage, liability (or action or
proceeding in respect thereof) or expense arises out of such Person's failure
to send or give a copy of the final prospectus, as the same may be then
supplemented or amended, to the Person asserting an untrue statement or alleged
untrue statement or omission or alleged omission at or prior to the written
confirmation of the sale of Registrable Securities to such Person if such
statement or omission was corrected in such final prospectus. Such indemnity
shall remain in full force and effect regardless of any investigation made by
or on behalf of such seller or any such director, officer, underwriter or
controlling person and shall survive the transfer of such securities by such
seller.

         (b)      INDEMNIFICATION BY THE SELLERS.

                  The Company may require, as a condition to including any
Registrable Securities in any registration statement filed pursuant to Sections
5.1 or 5.2, that the Company shall have received an undertaking satisfactory to
it from the prospective seller of such securities, to indemnify and hold
harmless (in the same manner and to the same extent as set forth in Section
5.6(a) the Company's underwriter, the Company, each director of the Company,
each officer of the Company and each other Person, if any, who controls the
Company within the meaning of the Securities Act, with respect to any statement
or alleged statement in or omission or alleged omission from such registration
statement, any preliminary prospectus, final prospectus or summary prospectus
contained therein, or any amendment or supplement thereto, if such statement or
alleged statement or omission or alleged omission was made in reliance upon and
in conformity with written information furnished to the Company through an
instrument duly executed by such seller specifically stating that it is for use
in the preparation of such registration statement, preliminary prospectus,
final prospectus, summary prospectus, amendment or supplement, provided that
the obligation to indemnify will be several, not joint and several, among such
sellers of Registrable Securities and the liability of each such seller of
Registrable Securities will be in proportion to and limited to the net amount
received by such seller from the sale of Registrable Securities pursuant to
such registration statement. Such indemnity shall remain in full force and
effect, regardless of any investigation made by or on behalf of the

                                     - 29 -

<PAGE>   30

Company or any such director, officer or controlling person and shall survive
the transfer of such securities by such seller.

         (c)      NOTICES OF CLAIMS, ETC.

                  Promptly after receipt by an indemnified party of notice of
the commencement of any action or proceeding involving a claim referred to in
the preceding subdivisions of this Section 5.6, such indemnified party will, if
a claim in respect thereof is to be made against an indemnifying party, give
written notice to the latter of the commencement of such action, provided that
the failure of any indemnified party to give notice as provided herein shall
not relieve the indemnifying party of its obligations under the preceding
subdivisions of this Section 5.6, except to the extent that the indemnifying
party is actually prejudiced by such failure to give notice. In case any such
action is brought against an indemnified party, unless in such indemnified
party's reasonable judgment a conflict of interest between such indemnified and
indemnifying parties may exist in respect of such claim, the indemnifying party
shall be entitled to participate in and to assume the defense thereof, jointly
with any other indemnifying party similarly notified to the extent that it may
wish, with counsel reasonably satisfactory to such indemnified party, and after
notice from the indemnifying party to such indemnified party of its election so
to assume the defense thereof, the indemnifying party shall not be liable for
any settlement made by the indemnified party without its consent (which consent
will not be unreasonably withheld) or for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense
thereof other than reasonable costs of investigation. No indemnifying party
shall, without the consent of the indemnified party, consent to entry of any
judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
indemnified party of a release from all liability in respect to such claim or
litigation.

         (d)      OTHER INDEMNIFICATION.

                  Indemnification similar to that specified in the preceding
subdivisions of this Section 5.6 (with appropriate modifications) shall be
given by the Company and each seller of Registrable Securities with respect to
any required registration or other qualification of securities under any
federal or state law or regulation of any governmental authority other than the
Securities Act.

         (e)      INDEMNIFICATION PAYMENTS.

                  The indemnification required by this Section 5.6 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.

                                     - 30 -

<PAGE>   31

         (f)      CONTRIBUTION.

                  If the indemnification provided for in this Agreement shall
for any reason be unavailable or insufficient to an indemnified party under
Sections 5.6(a), 5.6(b) or 5.6(d) hereof in respect of any loss, claim,
damage or liability, or any action in respect thereof, or referred to therein,
then each indemnifying party shall, in lieu of indemnifying such party,
contribute to the amount paid or payable by such indemnified party as a result
of such loss, claim, damage or liability, or action in respect thereof, in such
proportion as shall be appropriate to reflect (i) the relative benefits
received by the Company on the one hand and the holders of the Registrable
Securities included in the offering on the other hand, from the offering of the
Registrable Securities, and (ii) the relative fault of the Company on the one
hand and the holders of the Registrable Securities included in the offering on
the other, with respect to the statements or omissions which resulted in such
loss, claim, damage or liability, or action in respect thereof, as well as any
other relevant equitable considerations. The relative benefits received by the
Company on the one hand and the holders of the Registrable Securities on the
other with respect to such offering shall be deemed to be in the same
proportion as the sum of the total Subscription Price paid to the Company in
respect of the Registrable Securities plus the total net proceeds from the
offering of the securities (before deducting expenses) received by the Company
bears to the amount by which the total net proceeds from the offering of the
securities (before deducting expenses) received by the holders of the
Registrable Securities with respect to such offering exceeds the Subscription
Price paid to the Company in respect of the Registrable Securities, and in each
case the net proceeds received from such offering shall be determined as set
forth on the table or the cover page of the prospectus. The relative fault
shall be determined by reference to, among other things, whether the untrue or
alleged untrue statement of a material fact or omission or alleged omission to
state a material fact relates to information supplied by the Company or the
holders of the Registrable Securities, the intent of the parties and their
relative knowledge, access to information and opportunity to correct or prevent
such statement or omission. The Company and the holders of the Registrable
Securities agree that it would not be just and equitable if contribution
pursuant to this Section 5.6 were to be determined by pro rata allocation or by
any other method of allocation which does not take into account the equitable
considerations referred to herein. The amount paid or payable by an indemnified
party as a result of the loss, claim, damage or liability, or action in respect
thereof, referred to in this Section 5.6 shall be deemed to include, for
purposes of this Section 5.6, 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.

                  (a)      All expenses incident to the Company's performance

securities or blue sky laws, all word processing, duplicating and printing

disbursements, including without limitation, out-of-pocket expenses of any
single counsel and accountants retained by the holder or holders of a majority
of the Registrable Securities being registered and any fees and disbursements
of underwriters customarily paid by issuers or sellers of securities (including
fees paid to a "qualified independent underwriter" required by the rules of the
NASD in connection with a distribution, but excluding discounts and commissions
and transfer taxes, if any) and other Persons retained by the Company (all such
expenses being herein called "Registration Expenses"), will be borne by the
Company, and in addition the Company will pay its internal expenses (including,
without limitation, all salaries and expenses of its officers and employees
performing legal or accounting duties), the expense of any annual audit or
quarterly review, the expense of any liability insurance, and the expenses and
fees for listing the securities to be registered on each securities exchange on
which similar securities issued by the Company are then listed or other
expenses for the preparation of financial statements or other data normally
prepared by the Company in the ordinary course of its business or which the
Company would have incurred in any event.

                  (b)      In connection with each Demand Registration, the
Company will reimburse the holders of Registrable Securities covered by such
registration for the reasonable fees and disbursements of one counsel chosen by
the holders of a majority of such Registrable Securities.

                  (c)      To the extent Registration Expenses are not required
to be paid by the Company, each holder of securities included in any
registration hereunder will pay those Registration Expenses allocable to the
registration of such holder's securities so included, and any Registration
Expenses not so allocable will be borne by all sellers of securities included
in such registration in proportion to the aggregate selling price of the
securities to be so registered.

         5.8.     ADJUSTMENTS AFFECTING REGISTRABLE SECURITIES.

                  The Company will not effect or permit to occur any
combination or subdivision of shares which would materially adversely affect
the ability of the holders of Registrable Securities to include such
Registrable Securities in any

                                     - 32 -

registration of its securities contemplated by this Section 5 or the
marketability of such Registrable Securities under any such registration.

         5.9.     PARTICIPATION IN UNDERWRITTEN REGISTRATIONS.

                  No Person may participate in any registration hereunder which
is underwritten unless such Person (a) agrees to sell such Person's securities
on the basis provided in any underwriting arrangements approved by the Person
or Persons entitled hereunder to approve such arrangements and (b) completes
and executes all questionnaires, powers of attorney, indemnities, underwriting
agreements and other documents required under the terms of such underwriting
arrangements.

         5.10.    RULE 144.

                  If the Company shall have filed a registration statement
pursuant to the requirements of Section 12 of the Exchange Act or a
registration statement pursuant to the requirements of the Securities Act, the
Company will file the reports required to be filed by it under the Securities
Act and the Exchange Act (or, if the Company is not required to file such
reports, will, upon the request of any holder of Registrable Securities, make
publicly available other information) and will take such further action as any
holder of Registrable Securities may reasonably request, all to the extent
required from time to time to enable such holder to sell Registrable Securities
without registration under the Securities Act within the limitation of the
exemptions provided by (a) Rule 144 or (b) any similar rule or regulation
hereafter adopted by the Commission. Upon the request of any holder of
Registrable Securities, the Company will deliver to such holder a written
statement as to whether it has complied with such requirements.

6.       BASIC FINANCIAL INFORMATION OF THE COMPANY.

         Notwithstanding any provision of the bylaws of the Company regarding

Company, until the Company becomes a reporting company under the Exchange Act,

shares of the Preferred Stock or own, as a class, at least ten percent (10%) of

7.       TRANSFERABILITY OF SECURITIES; COMPLIANCE WITH SECURITIES ACT.

         7.1.     TRANSFERABILITY.

                  (a)      As set forth below in this Section 7.1 and subject
to the terms of Section 7.1(b), an Investor may transfer its Limited
Securities; provided, however, that the Company is given written notice at the
time of such transfer stating the

                                     - 34 -

<PAGE>   35

names and addresses of the transferee and identifying the Limited Securities to
be transferred, and such transferee expressly agrees in writing with the
Company to be bound by and to comply with all applicable provisions of this
Agreement, whereupon such person or entity shall have the benefit of, and shall
be subject to the restrictions contained in, this Agreement with respect to
such Limited Securities. Notwithstanding the provisions of this Section 7, an
Investor may transfer on any public securities market or in any public offering
pursuant to Section 5, without the consent of the Company and without being
required to comply with the provisions of this Section 7, any of its Common
Stock and following such transfer the Common Stock so transferred shall be free
of the requirements of this Section 7.

                  (b)      Right of First Refusal.

                           (i)      As used in this Section 7.1(b), the terms
"purchase" and "transfer" mean any disposition for value, including without
limitation any sale, assignment, transfer, mortgage, pledge or hypothecation
for value. To be deemed to be a bona fide offer within the meaning of this
Section, an offer must be in writing, signed by the offeror (who must be
financially capable of carrying out the terms of the offer), and in a form
legally enforceable against the offeror, subject to standard and customary
conditions.

                           (ii)     Subject to Section 7.1(b)(i) hereof, if, at
any time or from time to time after the date of this Agreement, a holder of
Series C Preferred Stock (a "Series C Holder") receives a bona fide offer to
purchase all or any part of its Series C Preferred Stock, which offer the
Series C Holder intends to accept, the Series C Holder shall promptly give
notice to the Company and each of the Investors (the "First Refusal Notice").
The notice shall offer the Company the right to purchase the shares of the
Series C Preferred Stock which are the subject of the bona fide offer (the
"Subject Series C Shares"), at the same price and on the same terms as set
forth in the bona fide offer. The notice shall be accompanied by a copy or
description of the bona fide offer and shall set forth the name and business
address of the offeror. If the offeror is a corporation, the notice shall set
forth the name and address of the corporation and the names and addresses of
all persons owning 10% or more of the capital stock of the corporation.

                           (iii)    Subject to Section 7.1(b)(i), the Company
shall then have thirty (30) days from the date of the First Refusal Notice
delivered pursuant to Section 7.1 (b)(ii) in which to elect to purchase all or
a part of the Subject Series C Shares at the same price and on the same terms
as set forth in the bona fide offer.

                           (iv)     If the Company does not elect to purchase
all of the Subject Series C Shares within the 30-day period, the other
Investors (the "Nonoffering Investors") shall then have fifteen (15) days from
the end of the 30-day period in which to elect to purchase all or a part of the
Subject Series C Shares

                                     - 35 -

<PAGE>   36

which are not purchased by the Company (the "Leftover Series C Shares"). Each
Nonoffering Investor shall have the right to purchase its ratable portion of
the Leftover Series C Shares. If any Nonoffering Investor does not elect to
purchase all of its ratable portion of the Leftover Series C Shares within the
15-day period, then the remaining Nonoffering Investors (pro rata among
themselves, or in such other proportion as they may at such time agree upon)
shall have the right, within the 15-day period, to elect to purchase all or
part of the Leftover Series C Shares not elected to be purchased.

                           (v)      If the Nonoffering Investors and the
Company do not elect to purchase all of the Subject Series C Shares, then the
Series C Holder may then sell, and the bona fide offeror may purchase, all of
the Subject Series C Shares, but only in strict accordance with all of the
provisions of the bona fide offer and only if the purchase is fully consummated
within one hundred twenty (120) days after the giving of the notice required by
Section 7.1(b)(ii) hereof. In no event may a Series C Holder transfer its
Series C Preferred Stock to any competitor of the Company or any entity that
owns, directly or indirectly, in excess of 5% of the equity of a competitor of
the Company.

                           (vi)     Subject to Section 7.1(b)(i), if the
Company or the Nonoffering Investors elect to purchase any Subject Series C
Shares pursuant to this Section, closing on the purchase shall be held at a
mutually agreeable time within sixty (60) days after the election to purchase
is made, at the offices of the Company's attorney or such other place as may be
mutually agreeable.

                           (vii)    Subject Series C Shares transferred either
pursuant to the bona fide offer or the right of refusal created pursuant to
this Section shall remain subject to the terms of this Section 7.1(b).

         7.2.     RESTRICTIVE LEGEND.

         Each certificate representing (i) the shares of Preferred Stock, or
(ii) shares of Common Stock issued upon conversion of the shares of Preferred
Stock and (iii) any securities issued in respect of the shares of Preferred
Stock or such Common Stock, shall (unless otherwise permitted by the provisions
of Section 7.3 below) be stamped or otherwise imprinted with a legend
substantially in the following form (in addition to any legend required under
applicable state securities laws):

                  THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED

                  SECURITIES ACT OF 1933 OR ANY APPLICABLE STATE SECURITIES
                  LAWS. SUCH SHARES MAY NOT BE OFFERED, PLEDGED, SOLD OR
                  TRANSFERRED

                  IN THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION THEREFROM
                  AS DETERMINED IN ACCORDANCE WITH THE SECOND AMENDED AND
                  RESTATED INVESTOR RIGHTS AGREEMENT DATED AS OF NOVEMBER 4,
                  1998 RESTRICTING THEIR TRANSFER. COPIES OF THE INVESTOR
                  RIGHTS AGREEMENT MAY BE OBTAINED AT NO COST BY WRITTEN
                  REQUEST MADE BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO
                  THE SECRETARY OF THE CORPORATION AT THE CORPORATION'S
                  PRINCIPAL PLACE OF BUSINESS. FURTHER, THE DESIGNATIONS,
                  RELATIVE RIGHTS, PREFERENCES AND LIMITATIONS OF EACH CLASS OF
                  STOCK OF THE CORPORATION AND THE VARIATIONS IN THE RIGHTS,
                  PREFERENCES AND LIMITATIONS DETERMINED FOR EACH SERIES OF
                  STOCK (AND THE AUTHORITY OF THE BOARD OF DIRECTORS OF THE
                  CORPORATION TO DETERMINE VARIATIONS FOR FUTURE SERIES), ARE
                  SET FORTH IN THE CORPORATION'S CERTIFICATE OF INCORPORATION,
                  AS AMENDED, A COPY OF WHICH WILL BE FURNISHED BY THE
                  CORPORATION TO THE HOLDER OF THIS CERTIFICATE, WITHOUT
                  CHARGE, UPON THE WRITTEN REQUEST OF SUCH HOLDER.

         7.3.     NOTICE OF PROPOSED TRANSFERS.

         The holder of each certificate representing Limited Securities by
acceptance thereof agrees in writing to comply with the provisions of this
Section 7.3. Prior to any proposed transfer of any Limited Securities, unless
there is in effect a registration statement under the Securities Act covering
the proposed transfer, the holder thereof shall give written notice to the
Company of such holder's intention to effect such transfer. Each such notice
shall describe the manner and circumstances of the proposed transfer (including
the names of the transferees, if known) in sufficient detail, and shall be
accompanied (except in the following cases, with respect to which the
requirements set forth in the balance of this sentence need not be complied
with if the transferee agrees in writing to be bound by the then applicable
provisions of this Section 7: transactions in compliance with Rule 144 so long
as the Company is furnished with satisfactory evidence of compliance with such
Rule; transactions involving the distribution of Limited Securities in
accordance with the beneficial ownership thereof by any Investor to any
Authorized Transferee, so long as such transaction does not involve the
disposition of such Limited Securities for value; and transactions involving
the transfer of Limited

                                     - 37 -

<PAGE>   38

Securities by any holder who is an individual to any Authorized Transferee) by
either (i) an unqualified written opinion of legal counsel who shall be
reasonably satisfactory to the Company addressed to the Company and reasonably
satisfactory in form and substance to the Company's counsel, to the effect that
the proposed transfer of the Limited Securities may be effected without
registration under the Securities Act, or (ii) a "no action" letter from the
Commission to the effect that the distribution of such securities without
registration will not result in a recommendation by the staff of the Commission
that action be taken with respect thereto, whereupon the holder of such Limited
Securities shall be entitled to transfer such Limited Securities in accordance
with the terms of the notice delivered by the holder to the Company. Each
certificate evidencing the Limited Securities transferred as above provided
shall bear the appropriate restrictive legend set forth in Section 7.2 above,
except that such certificate shall not bear such restrictive legend if in the
reasonable opinion of counsel for the Company such legend is not required in
order to establish compliance with any provisions of the Securities Act.

8.       RIGHT OF FIRST REFUSAL FROM THE COMPANY.

         8.1.     PRO RATA RIGHT.

         The Company hereby grants to each Investor, for so long as the
Investors as a class are holders of shares of Preferred Stock convertible into
at least five percent (5%) of the outstanding Common Stock on a fully diluted
basis, or own, as a class, at least five percent (5%) of the outstanding Common
Stock on a fully diluted basis, the right of first refusal to purchase, pro
rata, all New Securities (as defined in Section 8.2 below) which the Company
may, from time to time, propose to sell and/or issue. An Investor's pro rata
share is a ratio (A) the numerator of which is the number of shares of Common
Stock issued or issuable upon conversion of the shares of Preferred Stock held
by such Investor, and (B) the denominator of which is the total number of
shares of Common Stock outstanding immediately prior to the issuance of the New
Securities assuming the conversion or exercise of all then outstanding
convertible securities (including the shares of Preferred Stock), options,
warrants or similar rights to acquire Common Stock and assuming the issuance of
all then unissued permitted employee shares (consistent with Article Fourth of
the Restated Certificate of Incorporation of the Company, as in effect on the
date hereof) (the "Pro Rata Share"). For purposes of this Section 8.1, the
number of shares of Preferred Stock held by such Investor shall be determined
as of the date of the Company's written notice pursuant to Section 8.3 below.
Each Investor shall have a right of over-allotment such that if any other
Investor or any holder of Common Stock having rights of first refusal with
respect to New Securities (together with the Investors, the "Holders") fails to
exercise its rights hereunder to purchase its Pro Rata Share of New Securities,
the other Holders may purchase each non-purchasing Holder's portion on a pro
rata basis within fifteen (15) days

                                     - 38 -

<PAGE>   39


from the date such non-purchasing Holder fails to exercise its right. This
right of first refusal shall be subject to all of the provisions of this
Section 8.

         8.2.     DEFINITION OF "NEW SECURITIES".

         "New Securities" shall mean any capital stock (including without
limitation the Common Stock and the Preferred Stock) of the Company whether now
authorized or not, and rights, options or warrants to purchase capital stock,
and securities of any type whatsoever that are, or may become, convertible into
capital stock; provided that the term "New Securities" does not include (i) the
Common Stock or other securities issuable upon conversion of or with respect to
any shares of Preferred Stock; (ii) the Common Stock or other securities
issued, or issuable, pursuant to the Company Employee Stock Plan, if any
(consistent with Article Fourth of the Restated Certificate of Incorporation),
and the employee specific options listed in Section 5.4 of the Schedule of
Exceptions; (iii) securities covered by a registration statement filed under
the Securities Act and offered to the public pursuant to a firm underwriting;
(iv) securities issued pursuant to the acquisition of another corporation by
the Company by merger or purchase of all or substantially all the assets of
such corporation; (v) any borrowings, direct or indirect, from financial
institutions or other persons by the Company, whether or-not presently
authorized, including any type of loan or payment evidenced by any type of debt
instrument, provided such borrowings do not have any equity features, including
warrants, options or other rights to purchase capital stock, and are not
convertible into capital stock of the Company; or (vi) securities issued
pursuant to any stock dividend, stock split, combination or other
reclassification by the Company of any of its capital stock.

         8.3.     REQUIRED NOTICE.

         In the event that the Company proposes to undertake an issuance of New
Securities, it shall give each Investor written notice of its intention,
describing the type of New Securities, the price and the general terms upon
which the Company proposes to issue the same. Each Investor shall have thirty
(30) days from the date of receipt of any such notice to agree to purchase such
Investor's Pro Rata Share of such New Securities for the price and upon the
general terms specified in the notice by giving written notice to the Company
and stating therein the quantity of New Securities to be purchased.

         8.4.     COMPANY'S RIGHT TO SELL.

         In the event an Investor fails within the thirty (30) day period set
forth above to agree to purchase the full pro-rata share to which such Investor
is pursuant to this Section 8 entitled to purchase and after the expiration of
the fifteen (15) day period for the exercise of the over-allotment provisions
of this Section 8, the

                                     - 39 -

<PAGE>   40

Company shall have ninety (90) days thereafter to sell or enter into an
agreement (pursuant to which the sale of New Securities covered thereby shall
be closed, if at all, within ninety (90) days from the date of said agreement)
to sell all such New Securities respecting which such Investor's option to
purchase was not exercised, at a price and upon general terms no more favorable
to the purchasers thereof than specified in the Company's notice delivered to
each Investor pursuant to Section 8.3. In the event the Company has not sold
within said ninety (90) day period, or entered into an agreement to sell, all
such New Securities within said ninety (90) day period (or sold and issued all
such New Securities in accordance with the foregoing within ninety (90) days
from the date of said agreement), the Company shall not thereafter issue or
sell any New Securities without first offering such New Securities to each
Investor in the manner provided above.

         8.5.     EXPIRATION OF RIGHT.

         The right of first refusal granted under this Agreement shall expire
upon the closing of an underwritten public offering of the Company's Common
Stock pursuant to an effective registration statement under the Securities Act,
or under other applicable securities regulations covering the offer and sale of
capital stock of the Company, in which (i) the gross proceeds received by the
Company exceed $20,000,000, and (ii) the Company uses a nationally recognized
underwriter approved by holders of a majority of the shares of the Preferred
Stock voting separately as a class (a "Qualified Public Offering").

9.       INVESTORS' RIGHT OF FIRST REFUSAL.

         Except for an Underwritten Offering or an Authorized Transfer of any
Securities of the Company, for so long as the Investors as a class are holders
of shares of Preferred Stock convertible into at least five percent (5%) of the
outstanding Common Stock on a fully diluted basis, or own, as a class, at least
five percent (5%) of the outstanding Common Stock on a fully diluted basis, if
any Common Stock Holder intends to transfer any interest in any Securities
representing at least ten percent (10%), singly or combined with all transfers
by such Common Stock Holder made since the date of this Agreement, of the
Common Stock on a fully diluted basis, such Common Stock Holder shall deliver a
written notice (the "First Refusal Notice") to each Investor at least thirty
(30) days prior to the proposed sale, which such notice shall specify the terms
and conditions upon which the proposed sale is intended to be consummated. Each
Investor shall have the option to purchase such Investor's Pro Rata Share of
the Securities proposed to be sold on the same terms and conditions as
specified in the First Refusal Notice in the manner hereinafter set forth. The
Investor shall give written notice (the "Purchase Notice") of such election to
the Common Stock Holder proposing to sell Securities and to the other Investors
within twenty (20) days after delivery of the First Refusal Notice. The
Purchase Notice shall indicate the number of Securities

                                     - 40 -

<PAGE>   41

proposed to be sold which such Investor is willing to purchase. If any Investor
exercises the option provided for in this Section 9, such Investor shall within
thirty (30) days after exercising such option deliver to the selling Common
Stock Holder a check in the amount of the purchase price for the Securities to
be sold, and the selling Common Stock Holder shall simultaneously deliver the
certificate or other instrument evidencing the Securities being sold. Each
Investor shall have a right of over-allotment such that if any Investor fails
to exercise its rights hereunder to purchase its Pro Rata Share of Securities,
the other Investors may purchase each non-purchasing Investor's portion within
fifteen (15) days from the date such non-purchasing Investor fails to exercise
its right. If the selling Common Stock Holder has not received a Purchase
Notice within twenty (20) days after delivery of the First Refusal Notice, the
option to purchase Securities provided for in this Section 9 shall expire
unexercised, and the selling Common Stock Holder shall thereafter have 60 days
to close the proposed sale specified in the First Refusal Notice; provided that
the option provided for in this Section 9 shall again be applicable following
such sixty day period. Each party to a purchase and sale pursuant to the
exercise of an option pursuant to this Section 9 shall bear such party's own
expenses. The rights of first refusal granted under this Section 9 shall expire
upon a Qualified Public Offering.

10.      RIGHT OF CO-SALE.

         Except for an Underwritten Offering or Authorized Transfers of any
securities of the Company (the "Securities"), for so long as the Investors as a
class are holders of shares of Preferred Stock convertible into at least five
percent (5%) of the outstanding Common Stock on a fully diluted basis, or own,
as a class, at least five percent (5%) of the outstanding Common Stock on a
fully diluted basis, if any holder of Common Stock identified in Exhibit B
(each a "Common Stock Holder") intends to transfer any interest in any
Securities representing at least ten percent (10%), singly or combined with all
transfers by such Common Stock Holder made since the date of this Agreement, of
the Common Stock on a fully diluted basis, the Common Stock Holder shall
deliver (and the Company shall require any Common Stock Holder not a party to
this Agreement to deliver) a written notice (the "Co-Sale Notice") to each
Investor, at least thirty (30) days prior to the proposed sale, which such
notice shall specify the terms and conditions upon which the proposed sale is
intended to be consummated. Each Investor shall have the option to participate
in such sale in the manner hereinafter set forth. To exercise the option, an
Investor shall give written notice (the "Participation Notice") of such
election to the selling Common Stock Holder within twenty (20) days after
receipt of the Co-Sale Notice. Thereupon, such Investor shall have the right to
sell Securities to the proposed purchaser upon the same terms and conditions
specified in the Co-Sale Notice (which terms and conditions must include the
types and class of Securities then held by the Common Stock Holder), pro rata
with the selling Common Stock Holder based upon his then current respective
holdings of Common Stock, and securities convertible into Common Stock, on a
fully diluted basis. The number of Securities

                                     - 41 -

<PAGE>   42

to be sold by the Common Stock Holder delivering the Co-Sale Notice shall be
reduced by the number of Securities such Investor elects to so sell. If such
Investor exercises such option, it shall bear its pro rata portion of expenses
incident to such sale. Failure by any Investor to exercise the option within
the twenty (20) day period shall be deemed a declination of any right to
participate in such sale, provided that such sale is completed within ninety
(90) days of expiration of such twenty (20) day period at a price and on terms
and conditions substantially similar to those set forth in the Co-Sale Notice.
Failure to meet the foregoing conditions shall require a new Co-Sale Notice and
right of co-sale with respect to such sale. The co-sale rights granted under
this Section 10 shall expire upon a Qualified Public Offering.

11.      COMMON STOCK HOLDERS' RIGHTS.

         11.1.    GENERAL RESTRICTIONS.

                  (a)      The provisions of this Section 11 shall be subject
to the Investors' cosale rights and rights of first refusal, in accordance with
the terms of Sections 9 and 10 hereof, respectively, if applicable. To the
extent that the provisions of Sections 9 and 10 are applicable, but the
Investors elect not to exercise in whole their rights under such Sections, then
and only then the terms of this Section 11 shall govern any transfer of Common
Stock by the Common Stock Holders.

                  (b)      Subject to Section 11.1(a), no Common Stock Holder
shall, directly or indirectly, sell, assign, transfer, convey, give, pledge,
bequeath or in any manner encumber or dispose of any of his Shares, to anyone,
including, without limitation, any other Common Stock Holder, except:

                           (1)      Upon the prior written consent of the
         majority of the other Common Stock Holders;

                           (2)      To any Authorized Transferee; and

                           (3)      In any other case, in accordance with the
         provisions of Section 11.2 or 11.3.

                  (c)      Notwithstanding, nor in limitation of any other
provision of this Agreement, any disposition of the Company's Common Stock in
violation of this Section 11 shall be void and shall not be recognized by the
Company for any purpose including, but not limited to, distributions, with
respect to the Company's shares and reporting to federal and state income tax
authorities, which shall continue in the name and under the tax identification
number of the shareholder who purports to have effected such void disposition.

                  (d)      The provisions of this Section 11 shall expire upon
a Qualified Public Offering.

         11.2.    RIGHT OF FIRST REFUSAL.

                  (a)      As used in this Section 11, the term "purchase"
means any disposition for value, including without limitation any sale,
assignment, transfer, mortgage, pledge or hypothecation for value. To be deemed
to be a bona fide offer within the meaning of this Section, an offer must be in
writing, signed by the offeror (who must be financially capable of carrying out
the terms of the offer), and in a form legally enforceable against the offeror.

                  (b)      Subject to Section 11.1(a) hereof, if, at any time
or from time to time after the date of this Agreement, a Common Stock Holder
receives a bona fide offer to purchase all or any part of his Common Stock,
which offer the Common Stock Holder intends to accept, the Common Stock Holder
shall promptly give notice to the Company and each of the other Common Stock
Holders. The notice shall offer the Company the right to purchase the Common
Stock which are the subject of the bona fide offer (the "Subject Shares"), at
the same price and on the same terms as set forth in the bona fide offer. The
notice shall be accompanied by a copy of the bona fide offer and shall set
forth the name and business address of the offeror. If the offeror is a
corporation, the notice shall set forth the name and address of the corporation
and, unless the proposed disposition will be to secure a bona fide loan to be
extended by the offeror in the normal course of its lending business, the names
and addresses of all persons owning 10% or more of the capital stock of the
corporation. The giving of this notice shall constitute a warranty and
representation by the offering Common Stock Holder to the Company and the other
Common Stock Holders that the offering Common Stock Holder believes the offer
to be bona fide in all respects.

                  (c)      Subject to Section 11.1(a), the Company shall then
have sixty (60) days from the date of the First Refusal Notice in which to
elect to purchase all or a part of the Subject Shares at the same price and on
the same terms as set forth in the bona fide offer.

                  (d)      If the Company does not elect to purchase all of the
Subject Shares within the 60-day period and the Investors have decided not to
exercise their rights, if any, pursuant to Section 9, the other Common Stock
Holders shall then have fifteen (15) days from the end of the 60-day period in
which to elect to purchase all or a part of the Subject Shares which are not
purchased by the Company or any of the Investors (the "Leftover Shares"). Each
Common Stock Holder shall have the right to purchase his ratable portion of the
Leftover Shares. If any other Common Stock Holder does not elect to purchase
all of his ratable portion of the Leftover Shares within the 15-day period,
then the remaining Common Stock Holders (pro rata among themselves, or in such
other proportion as

                                     - 43 -

<PAGE>   44

they may at such time agree upon) shall have the right, within the 15-day
period, to elect to purchase all or part of the Leftover Shares not elected to
be purchased.

                  (e)      If the Investors, the Company and the other Common
Stock Holders do not elect, within the specified time periods, to purchase all
of the Subject Shares, then unless a majority of the remaining Common Stock
Holders object in writing to such sale, the Offering Common Stock Holder may
then sell, and the bona fide offeror may purchase, all or part of the Subject
Shares which are not purchased, but only in strict accordance with all of the
provisions of the bona fide offer and only if the purchase is fully consummated
within one hundred twenty (120) days after the giving of the notice required by
Section 11.2(b) hereof. The remaining Common Stock Holders' objections shall
not be unreasonable.

                  (f)      Subject to Section 11.1(a), if the Company or the
other Common Stock Holders elect to purchase any Subject Shares pursuant to
this Section, closing on the purchase shall be held at a mutually agreeable
time within sixty (60) days after the election to purchase is made, at the
offices of the Company's attorney or such other place as may be mutually
agreeable.

                  (g)      Subject Shares transferred either pursuant to the
bona fide offer or the right of refusal created pursuant to this Section shall
remain subject to the terms of this Section 11.

         11.3.    BUY-OUT PROVISIONS.

                  (a)      Subject to Section 11.1(a) hereof, a Common Stock
Holder (the "Offering Common Stock Holder") shall be deemed to grant an option
(the "Call Option") to purchase all, but not less than all, of the offering
Common Stock Holder's Shares, upon the occurrence of any of the following
events ("Option Events"):

                           (1)      The death of the Offering Common Stock
Holder.

                           (2)      The permanent disability of the Offering
Common Stock Holder.  "Disability" means the incapacity, due to mental or
physical illness or accident, which prevents the person in question from
gainfully engaging in and performing his duties for the Company at a level of
performance substantially equal to the level of which he is capable on the date
of this Agreement. "Permanent disability" means a disability which lasts for
more than nine (9) continuous months.

                           (3)      The termination of the Offering Common
Stock Holders' employment with the Company voluntarily or for any reason
permitted under the terms of the Common Stock Holders' employment agreement
with the Company.

                                     - 44 -

<PAGE>   45

                  (b)      A Call Option shall be deemed to be created
immediately upon the occurrence of an Option Event, and shall expire on the
90th day after the Company has written notice of the Option Event. For purposes
of Section 9 (Investor's First Right of Refusal), a Call Option shall
constitute an intention by the Offering Common Stockholder to transfer his
stock on the terms contained in this Section 11.3. Subject to Section 11.1(a),
a Call Option shall run initially in favor of the Company. If the Company
declines to exercise the Call Option, or fails to exercise the Call Option
within sixty (60) days from receipt of written notice of the Option Event, the
Call Option shall run in favor of the other Common Stock Holders (in proportion
to their respective ownership of Common Stock or as they otherwise agree) for
the remainder of its period of effectiveness. If the Company has declined or
failed to exercise its Call Option and any Common Stock Holder has failed to
exercise his or her Call Option within fifteen days of the date it first
becomes exercisable then the remaining Common Stock Holders (pro rata among
themselves, or in such other proportion as they may at such time agree upon)
shall have the right, within the remaining period of the Call Option to elect
to purchase all or part of the shares subject to the Call Option as to which
the Call Option has not then been exercised.

                  (c)      A Call Option may be exercised solely by written
notice to the Offering Common Stock Holder or his or her personal
representative delivered by the Investors, the Company or the other Common
Stock Holders, as the case may be. A Call Option may be exercised only as to
all of the Offering Common Stock Holder's Common Stock. (Thus, for example, if
the Investors and the Company decline and one of the other Common Stock Holders
refuses to exercise the Call Option and refuses to permit the other Common
Stock Holder to purchase his portion, the Call Option cannot be exercised.)

                  (d)      If a Call Option is exercised, closing on the
purchase of the Offering Common Stock Holder's Common Stock shall be conducted
not later than sixty (60) days after the exercise at the offices of the
Company's attorney. The purchase price of the Common Stock subject to the Call
Option shall be their "Fair Market Value," as defined below, and shall be
payable at such closing in cash or bank check.

                  (e)      The "Fair Market Value" of Common Stock subject to a
Call Option shall be determined by appraisal if not otherwise agreed to by the
parties. The Company shall appoint an appraiser, who shall make his appraisal
within twenty-one (21) days after his appointment. If the Offering Common Stock
Holder disputes the result of the appraisal, he may appoint an appraiser within
ten (10) days after the first appraiser delivers his report, and the second
appraiser shall deliver his report within twenty-one (21) days after his
appointment. The Company may dispute the second appraisers report within ten
days after it has been delivered to the Company in which case the first two
appraisers, within after the Company registers its dispute, shall appoint a
third. If the Company fails to dispute the

                                     - 45 -

<PAGE>   46

second appraisal, it shall be deemed to have accepted it. The third appraiser
shall deliver his report within ten days (10) after his appointment, and his
report shall govern, except that the price shall not be lower than the lower of
the first two (2) appraisals or higher than the higher of the first two (2)
appraisals. The results of the appraisal shall be final, conclusive and binding
on the parties. All appraisers shall be disinterested persons of recognized
competence in appraising values of similar communications businesses. All
appraisals shall be in writing. Each appraiser shall appraise on the basis of
all relevant factors in accordance with generally accepted appraisal techniques
for businesses similar to the business of the Company. The expense of the first
appraisal shall be shared equally by the Company and the Offering Common Stock
Holder if it is not disputed. In the event the first appraisal is disputed the
Company shall bear the cost of the second appraisal and the Offering Common
Stock Holder the cost of the first appraisal. The cost of the third appraisal,
if any, shall be borne by the party whose appraisal is furthermost in value
from the value established by the third appraisal.

                  (f)      Settlement of any purchase under this Section 11.3
shall be held within sixty (60) days of the final determination of Fair Market
Value of the Common Stock subject to the Call Option. Payment for the Common
Stock purchased pursuant to the Call Option shall be paid as follows: cash at
settlement to the extent of twenty-five (25%) percent of the purchase price,
with the balance of the purchase price to be paid by a promissory note(s) of
the party or parties exercising the Option. The principal amount of the note(s)
shall: (i) be equal to the balance of the purchase price and the note(s) shall
be dated as of the date of settlement; (ii) bear interest, payable quarterly,
from the date thereof on the unpaid balance at the prime rate as established by
Citibank, N.A. or its successor on the date of such note to be adjusted
annually on each subsequent anniversary, plus two percent (2%), (but in no
event shall the total interest rate exceed ten percent (10%) per annum); (iii)
be payable in five (5) equal consecutive annual installments with the first
payment due one (1) year after the date of settlement; and (iv) give the maker
the right to prepay the principal thereof in whole or in part at the time
without penalty.

                  (g)      The Company may acquire life insurance or disability
insurance policies to fund all or a portion of the purchase price of the Call
Option arising on a Common Stock Holder's death or permanent disability.

         11.4.    EFFECT ON TRANSFEREES.

                  Any person, other than the Investors, who becomes an owner of
any Common Stock pursuant to a disposition permitted by Section 11.2 or 11.3
shall be bound by the provisions of this Agreement with respect to such Shares,
whether or not such person becomes a party to this Agreement.

         11.5.    ENDORSEMENTS ON SHARE CERTIFICATES.

                  Each certificate evidencing any Common Stock of the Common
Stock Holders shall bear conspicuously a legend in substantially the following
form:

                  The transfer of the shares represented by this certificate is
                  restricted under the terms of a Second Amended and Restated
                  Investor Rights Agreement dated as of November 4, 1998, to
                  which the Company is a party. The Company will mail to the
                  shareholder of the shares represented by this certificate a
                  copy of the Investor Rights Agreement without charge within
                  five days after receipt of written request therefor.

         11.6.    ARBITRATION.

                  Except to the extent that the disputants agree in writing to
any other method of resolution of a given dispute and except to the extent the
resolution of any question is final, binding and conclusive upon the Common
Stock Holders under the terms of this Section 11, any dispute arising among the
Common Stock Holders, or any of them, or their successors-in-interest, or the
estate of a deceased Common Stock Holder, concerning the meaning or
interpretation of this Section 11, or the rights, duties or obligations of the
Common Stock Holders, including the successor-in-interest and the estate of a
deceased Common Stock Holder, shall, within reasonable promptness, be submitted
to, and determined by arbitration by the American Arbitration Association in
accordance with its rules then in force and effect, and judgment upon any award
rendered may be entered in any court having jurisdiction thereof, any such
party may, if he so elects, institute proceedings in any court having
jurisdiction for the specific performance by any party of any such award.

12.      INDEMNIFICATION; REMEDIES.

         12.1.    AGREEMENT OF THE COMPANY TO INDEMNIFY.

         Subject to the conditions and provisions of this Section 12, the
Company hereby agrees to indemnify, defend and hold harmless the Investor
Indemnified Persons from and against and in any respect of all Claims asserted
against, imposed upon or incurred by the Investor Indemnified Persons (whether
such Claims are by, against or relate to the Company, its Subsidiaries or any
other party, including a governmental entity), directly or indirectly, by reason
of or resulting from any misrepresentation or noncompliance with any conditions
or other agreements, given or made by the Company in this Agreement or in the

                                     - 47 -

furnished by or on behalf of the Company pursuant to this Agreement.

         12.2.    CONDITIONS OF INDEMNIFICATION.

         The obligations and liabilities of the Company hereunder with respect
to its indemnities pursuant to this Section 12.2, resulting from any Claim
shall be subject to the following terms and conditions:

                  (a)      The indemnified party shall give prompt written
notice to the Company of any Claim which is asserted against, imposed upon or
incurred by such indemnified party and which may give rise to liability of the
Company pursuant to this Section 12, stating (to the extent known or reasonably
anticipated) the nature and basis of such Claim and the amount thereof.

                  (b)      The indemnified party may engage counsel or
representatives of its own choosing with respect to any such Claim, such
representation (including the compromise or settlement of any Claim) to be
undertaken on behalf of and for the account and risk of the indemnifying party.
In the event the indemnified party elects not to undertake such defense by its
own representatives, the indemnified party shall give prompt written notice of
such election to the indemnifying party, and the indemnifying party will
undertake the defense thereof by counsel or other representatives designated by
it whom the indemnified party determines in writing to be satisfactory for such
purposes. The consent of the indemnified party to the indemnifying party's
choice of counsel or other representative shall not be unreasonably withheld.

         12.3.    SPECIFIC PERFORMANCE.

         In addition to any other remedies which any Investor may have at law
or in equity, the Company hereby acknowledges that the shares of Preferred
Stock and the Company and the Subsidiaries are unique, and that the harm to
each Investor resulting from breaches by the Company of its obligations cannot
be adequately compensated by damages. Accordingly, the Company agrees that each
Investor shall have the right to have all obligations, undertakings,
agreements, covenants and other provisions of this Agreement specifically
performed by the Company, and that each Investor shall have the right to obtain
an order or decree of such specific performance in any of the courts of the
United States of America or of any state or other political subdivision
thereof.

any other remedies against the Company, or its successors or assigns; provided,
however, that in no

                                     - 48 -

Company), at any time and from time to time, into or from a share of non-voting
preferred stock or non-voting common stock, respectively, which share shall
have the same rights, preferences and privileges as the Preferred Stock or
Common Stock, as the case may be, except that such share shall have no voting
rights. The Company agrees, at the request of SG and to take such action as is

     Re: Net2000 Communications Inc - Lock-Up Agreement

Ladies and Gentlemen:

     The undersigned understands that you, as representatives (the
"Representatives"), propose to enter into an Underwriting Agreement on behalf of
the several Underwriters named in Schedule I to such agreement (collectively,
the "Underwriters"), with Net2000 Communications, Inc., a Delaware corporation
(the "Company"), providing for a public offering of the Common Stock of the
Company (the "Shares") pursuant to a Registration Statement on Form S-1 to be
filed with the Securities and Exchange Commission (the "SEC").

     In consideration of the agreement by the Underwriters to offer and sell the
Shares, and of other good and valuable consideration the receipt and sufficiency
of which is hereby acknowledged, the undersigned agrees that, during the period
beginning from the date of the final Prospectus covering the public offering of
the Shares and continuing to and including the date 180 days after the date of
such final Prospectus, the undersigned will not offer, sell, contract to sell,
pledge, grant any option to purchase, make any short sale or otherwise dispose
of any shares of Common Stock of the Company, or any options or warrants to
purchase any shares of Common Stock of the Company, or any securities
convertible into, exchangeable for or that represent the right to receive shares
of Common Stock of the Company, whether now owned or hereinafter acquired, owned
directly by the undersigned (including holding as a custodian) or with respect
to which the undersigned has beneficial ownership within the rules and
regulations of the SEC (collectively the "Undersigned's Shares").

     The foregoing restriction is expressly agreed to preclude the undersigned
from engaging in any hedging or other transaction which is designed to or which
reasonably could be expected to lead to or result in a sale or disposition of
the Undersigned's Shares even if such Shares would be disposed of by someone
other than the undersigned.  Such prohibited hedging or other transactions would
include without limitation any short sale or any purchase, sale or grant of any
right (including without limitation any put or call option) with respect to any
of the Undersigned's Shares or with respect to any security that includes,
relates to, or derives any significant part of its value from such Shares.

     Notwithstanding the foregoing, the undersigned may transfer the
Undersigned's Shares (i) as a bona fide gift or gifts, provided that the donee
or donees thereof agree to be bound in writing by the restrictions set forth
herein, (ii) to any trust for the direct or indirect benefit of the undersigned
or the immediate family of the undersigned, provided that the trustee of the
trust agrees to be bound in writing by the restrictions set forth herein, and
provided further that any such transfer shall not involve a disposition for
value, or (iii) with the prior written consent of Goldman, Sachs & Co. on behalf
of the Underwriters.  For purposes of this Lock-Up Agreement, "immediate family"
shall mean any relationship by blood, marriage or adoption, not more remote than
first cousin.  In addition, notwithstanding the foregoing, if the undersigned is
a corporation, the corporation may transfer the capital stock of the

<PAGE>   2
Company to any wholly-owned subsidiary of such corporation; provided however,
that in any such case, it shall be a condition to the transfer that the
transferee execute an agreement stating that the transferee is receiving and
holding such capital stock subject to the provisions of this Agreement and there
shall be no further transfer of such capital stock except in accordance with
this Agreement, and provided further that any such transfer shall not involve a
disposition for value.  The undersigned now has, and, except as contemplated by
clause (i), (ii), or (iii) above, for the duration of this Lock-Up Agreement
will have, good and marketable title to the Undersigned's Shares, free and clear
of all liens, encumbrances, and claims whatsoever. The undersigned also agrees
and consents to the entry of stop transfer instructions with the Company's
transfer agent and registrar against the transfer of the Undersigned's Shares
except in compliance with the foregoing restrictions.

     The undersigned understands that the Company and the Underwriters are
relying upon this Lock-Up Agreement in proceeding toward consummation of the
offering.  The undersigned further understands that this Lock-Up Agreement is
irrevocable and shall be binding upon the undersigned's heirs, legal
representatives, successors, and assigns.


                                       Very truly yours,
