   Schedule II

   All other schedules for which provision is made in the applicable accounting
regulations of the Securities and Exchange Commission are not required under
the related instructions or are inapplicable, and therefore have been omitted.

Item 17. Undertakings.

   Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions described in Item 14 above, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

   The undersigned registrant hereby undertakes (1) to provide to the
underwriters at the closing specified in the underwriting agreement,
certificates in such denominations and registered in such names as required by
the underwriters to permit prompt delivery to each purchaser; (2) that for
purposes of determining any liability under the Securities Act, the information
omitted from the form

                                      II-5
<PAGE>

of prospectus filed as part of this registration statement in reliance upon
Rule 430A and contained in a form of prospectus filed by the registrant
pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be
deemed to be part of this registration statement as of the time it was declared
effective; and (3) that for the purpose of determining any liability under the
Securities Act, each post-effective amendment that contains a form of
prospectus shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.

DEUTSCHE BANK SECURITIES INC.
DONALDSON, LUFKIN & JENRETTE
SECURITIES CORPORATION
LEHMAN BROTHERS INC.
DLJdirect Inc.
As representatives of the several Underwriters
 named in Schedule I hereto
 c/o Deutsche Bank Securities Inc.
 One South Street
 Baltimore, Maryland 21202

Dear Sirs:

     DSL.net, Inc., a Delaware corporation (the "COMPANY"), proposes to issue
and sell ____________ shares of its common stock, $.0005 par value per share
(the "FIRM SHARES"), to the several underwriters named in Schedule I hereto (the
"UNDERWRITERS").  The Company also proposes to issue and sell to the several
Underwriters not more than an additional _______ shares of its common stock,
$.0005 par value per share (the "ADDITIONAL SHARES"), if requested by the
Underwriters as provided in Section 2 hereof.  The Firm Shares and the
Additional Shares are hereinafter referred to collectively as the "SHARES". The
shares of common stock of the Company to be outstanding after giving effect to
the sales contemplated hereby are hereinafter referred to as the "COMMON STOCK".

     SECTION 1.  Registration Statement and Prospectus.  The Company has
prepared and filed with the Securities and Exchange Commission (the
"COMMISSION") in accordance with the provisions of the Securities Act of 1933,
as amended, and the rules and regulations of the Commission thereunder
(collectively, the "ACT"), a registration statement on Form S-1, including a
prospectus, relating to the Shares. The registration statement, as amended at
the time it became effective, including the information (if any) deemed to be
part of the registration statement at the time of effectiveness pursuant to Rule
430A under the Act, is hereinafter referred to as the "REGISTRATION STATEMENT";
and the prospectus in the form first used to confirm sales of Shares is
hereinafter referred to as the "PROSPECTUS". If the Company has filed or is
required pursuant to the terms hereof to file a registration statement pursuant
to Rule 462(b)

- -----------------
/1/ Insert number of shares to be sold (not including green shoe).
<PAGE>

under the Act registering additional shares of Common Stock (a "RULE
462(b) REGISTRATION STATEMENT"), then, unless otherwise specified, any reference
herein to the term "Registration Statement" shall be deemed to include such Rule
462(b) Registration Statement.

     SECTION 2. Agreements to Sell and Purchase and Lock-Up Agreements. On the
basis of the representations and warranties contained in this Agreement, and
subject to its terms and conditions, the Company agrees to issue and sell, and
each Underwriter agrees, severally and not jointly, to purchase from the Company
at a price per Share of $______ (the "PURCHASE PRICE") the number of Firm Shares
set forth opposite the name of such Underwriter in Schedule I hereto.

     On the basis of the representations and warranties contained in this
Agreement, and subject to its terms and conditions, the Company agrees to issue
and sell the Additional Shares and the Underwriters shall have the right to
purchase, severally and not jointly, up to _______ Additional Shares from the
Company at the Purchase Price.  Additional Shares may be purchased solely for
the purpose of covering over-allotments made in connection with the offering of
the Firm Shares.  The Underwriters may exercise their right to purchase
Additional Shares in whole or in part from time to time by giving written notice
thereof to the Company within 30 days after the date of this Agreement.  You
shall give any such notice on behalf of the Underwriters and such notice shall
specify the aggregate number of Additional Shares to be purchased pursuant to
such exercise and the date for payment and delivery thereof, which date shall be
a business day (i) no earlier than two business days after such notice has been
given (and, in any event, no earlier than the Closing Date (as hereinafter
defined)) and (ii) no later than ten business days after such notice has been
given.  If any Additional Shares are to be purchased, each Underwriter,
severally and not jointly, agrees to purchase from the Company the number of
Additional Shares (subject to such adjustments to eliminate fractional shares as
you may determine) which bears the same proportion to the total number of
Additional Shares to be purchased from the Company as the number of Firm Shares
set forth opposite the name of such Underwriter in Schedule I bears to the total
number of Firm Shares.

     The Company hereby agrees not to (i) 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 purchase, or otherwise transfer or
dispose of, directly or indirectly, any shares of Common Stock or any securities
convertible into or exercisable or exchangeable for Common Stock or (ii) enter
into any swap or other arrangement that transfers all or a portion of the
economic consequences associated with the ownership of any Common Stock
(regardless of whether any of the transactions described in clause (i) or (ii)
is to be settled by the delivery of Common Stock, or such other securities, in
cash or otherwise), except to the Underwriters pursuant to this Agreement, for a
period of 180 days after the date of the Prospectus without the prior written
consent of Deutsche Bank Securities Inc. Notwithstanding the foregoing, during
such  period (i) the Company may grant stock options pursuant to the Company's
existing stock option plan and employee stock purchase plan, (ii) the Company
may issue shares of Common Stock upon the exercise of an option or warrant or
the conversion of a security outstanding on the date hereof granted or issued
under the Company's existing stock option plan or employee stock purchase plan,
and (iii) the Company may issue shares of Common Stock and other securities
convertible into or exercisable or exchangeable for shares of Common Stock in
connection with acquisitions (including asset acquisitions) and strategic
partner relationships, provided that, each holder of such Common Stock or such
other securities shall, prior to or concurrently with the issuance of

                                       2

such Common Stock or other securities, agree in writing to be bound by
restrictions set forth in the agreements described in the last sentence of this
paragraph. The Company also agrees not to file any registration statement (other
than a registration statement on Form S-8 registering Common Stock issuable
under the Company's existing stock option plan and employee stock purchase plan)
with respect to any shares of Common Stock or any securities convertible into or
exercisable or exchangeable for Common Stock for a period of 180 days after the
date of the Prospectus without the prior written consent of Deutsche Bank
Securities Inc. The Company shall, prior to or concurrently with the execution
of this Agreement, deliver an agreement executed by (i) each of the directors
and officers of the Company and (ii) each stockholder of the Company (other than
those listed on Annex I hereto), to the effect that such person will not, except
as provided therein, during the period commencing on the date such person signs
such agreement and ending 180 days after the date of the Prospectus, without the
prior written consent of Deutsche Bank Securities Inc., (A) engage in any of the
transactions described in the first sentence of this paragraph or (B) make any
demand for, or exercise any right with respect to, the registration of any
shares of Common Stock or any securities convertible into or exercisable or
exchangeable for Common Stock.

Underwriters propose (i) to make a public offering of their respective portions
of the Shares as soon after the execution and delivery of this Agreement as in
your judgment is advisable and (ii) initially to offer the Shares upon the terms

respects with the Act, and did not contain an untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary
to make the statements therein, in the light of the circumstances under which

omission or alleged material misstatement or omission that was cured in any

supplemented, or statements or omissions in any preliminary prospectus based

by such Underwriter through you expressly for use therein.

qualified and is in good standing as a foreign corporation or limited liability
company, as applicable, authorized to do business in each jurisdiction in which
the nature of its business or its ownership or leasing of property requires such

material adverse effect on the business, prospects, financial condition or
results of operations of the Company and its subsidiaries, taken as a whole.

     (e)  There are no outstanding subscriptions, rights, warrants, options,
calls, convertible securities, commitments of sale or liens granted or issued by

the Shares have been duly authorized and, when issued and delivered to the
Underwriters against payment therefor as provided by this Agreement, will be
validly issued, fully paid and non-assessable, and the issuance of such Shares
will not be subject to any preemptive or similar rights.

by which the Company or any of its subsidiaries or their respective property is
bound.

     (j)  The execution, delivery and performance of this Agreement by the
Company, the compliance by the Company with all the provisions hereof and the
consummation of the transactions contemplated hereby will not (i) require any
consent, approval, authorization or other order of, or qualification with, any

the various states), (ii) conflict with or constitute a breach of any of the
terms or provisions of, or a default under, the charter or limited liability
company agreement, as applicable or by-laws of the Company or any of its

documents that are required to be described in the Registration Statement or the
Prospectus or to be filed as exhibits to the Registration Statement that are not
so described or filed as required.

     (l)  Neither the Company nor any of its subsidiaries has violated any
foreign, federal, state or local law or regulation relating to the protection of
human health and safety, the environment or hazardous or toxic substances or
wastes, pollutants or contaminants

                                       8

("ENVIRONMENTAL LAWS"), any provisions of the Employee Retirement Income
Security Act of 1974, as amended, or any provisions of the Foreign Corrupt
Practices Act, or the rules and regulations promulgated thereunder, except for
such violations which, singly or in the aggregate, would not have a material
adverse effect on the business, prospects, financial condition or results of
operation of the Company and its subsidiaries, taken as a whole.

     (m)  Each of the Company and its subsidiaries has such permits, licenses,
consents, exemptions, franchises, authorizations and other approvals (each, an
"AUTHORIZATION") of, and has made all filings with and notices to, all
governmental or regulatory authorities and self-regulatory organizations and all
courts and other tribunals, including, without limitation, under any applicable
Environmental Laws, as are necessary to own, lease, license and operate its
respective properties and to conduct its business, except where the failure to
have any such Authorization or to make any such filing or notice would not,
singly or in the aggregate, have a material adverse effect on the business,
prospects, financial condition or results of operations of the Company and its
subsidiaries, taken as a whole. Each such Authorization is valid and in full
force and effect and each of the Company and its subsidiaries is in compliance
with all the terms and conditions thereof and with the rules and regulations of
the authorities and governing bodies having jurisdiction with respect thereto;
and no event has occurred (including, without limitation, the receipt of any
notice from any authority or governing body) which allows or, after notice or
lapse of time or both, would allow, revocation, suspension or termination of any
such Authorization or results or, after notice or lapse of time or both, would
result in any other impairment of the rights of the holder of any such
Authorization; and such Authorizations contain no restrictions that are
burdensome to the Company or any of its subsidiaries; except as is disclosed in
the Registration Statement or where such failure to be valid and in full force
and effect or to be in compliance, the occurrence of any such event or the
presence of any such restriction would not, singly or in the aggregate, have a
material adverse effect on the business, prospects, financial condition or
results of operations of the Company and its subsidiaries, taken as a whole.

     (n)  There are no costs or liabilities associated with Environmental Laws
(including, without limitation, any capital or operating expenditures required
for clean-up, closure of properties or compliance with Environmental Laws or any
Authorization, any related constraints on operating activities and any potential
liabilities to third parties) which would, singly or in the aggregate, have a
material adverse effect on the business, prospects, financial condition or
results of operations of the Company and its subsidiaries, taken as a whole.

     (o)  This Agreement has been duly authorized, executed and delivered by the
Company.

     (p)  PricewaterhouseCoopers LLP are independent public accountants with
respect to the Company and its subsidiaries as required by the Act.

     (q)  The consolidated financial statements included in the Registration
Statement and the Prospectus (and any amendment or supplement thereto), together
with related schedules and notes, present fairly the consolidated financial
position, results of operations and changes in financial position of the Company
and its subsidiaries on the basis stated therein at the respective dates or for
the respective periods to which they apply; such statements and related
schedules and notes have been prepared in accordance with generally accepted
accounting principles

                                       9
<PAGE>

consistently applied throughout the periods involved, except as disclosed
therein; the supporting schedules, if any, included in the Registration
Statement present fairly in accordance with generally accepted accounting
principles the information required to be stated therein; and the other
financial and statistical information and data set forth in the Registration
Statement and the Prospectus (and any amendment or supplement thereto) are, in
all material respects, accurately presented and prepared on a basis consistent
with such financial statements and the books and records of the Company.

     (r)  The Company is not and, after giving effect to the offering and sale
of the Shares and the application of the proceeds thereof as described in the
Prospectus, will not be, an "investment company" as such term is defined in the
Investment Company Act of 1940, as amended.

     (s)  Except as disclosed in the Registration Statement, there are no
contracts, agreements or understandings between the Company and any person
granting such person the right to require the Company to file a registration
statement under the Act with respect to any securities of the Company or to
require the Company to include such securities with the Shares registered
pursuant to the Registration Statement.

     (t)  Since the respective dates as of which information is given in the
Prospectus other than as set forth in the Prospectus (exclusive of any
amendments or supplements thereto subsequent to the date of this Agreement), (i)
there has not occurred any material adverse change or any development involving
a prospective material adverse change in the condition, financial or otherwise,
or the earnings, business, management or operations of the Company and its
subsidiaries, taken as a whole, (ii) there has not been any material adverse
change or any development involving a prospective material adverse change in the
capital stock or in the long-term debt of the Company or any of its subsidiaries
and (iii) neither the Company nor any of its subsidiaries has incurred any

     (u)  Each certificate signed by any officer of the Company and delivered
to the Underwriters or counsel for the Underwriters shall be deemed to be a
representation and warranty by the Company to the Underwriters as to the matters
covered thereby.

     (v)  Neither the Company nor any of its subsidiaries owns any real
property. The Company and its Subsidiaries have good and marketable title to all
personal property owned by them which is material to the business of the Company
and its subsidiaries, taken as a whole, in each case free and clear of all
liens, encumbrances and defects except such as are described in the Prospectus
or such as do not materially affect the value of such property and do not
materially interfere with the use made and proposed to be made of such property
by the Company and its subsidiaries; and any real property and buildings held
under lease by the Company and its subsidiaries are held by them under valid,
subsisting and enforceable leases with such exceptions as are not material and
do not materially interfere with the use made and proposed to be made of such
property and buildings by the Company and its subsidiaries, taken as a whole, in
each case except as described in the Prospectus.

                                       10

     (w)  The Company and its subsidiaries own, or possess valid and enforceable
licenses to, or rights to use, all patents, patent rights, inventions,
copyrights, know-how (including trade secrets and other unpatented and/or
unpatentable proprietary or confidential information, systems or procedures),
trademarks, service marks and trade names ("INTELLECTUAL PROPERTY") currently
employed by the Company and its subsidiaries in connection with the business now
operated by them, except where the failure to own or possess licenses for or
rights to use such Intellectual Property would not, singly or in the aggregate,
have a material adverse effect on the business, prospects, financial condition
or results of operation of the Company and its subsidiaries, taken as a whole.
Neither the Company, nor its subsidiaries, has received any written notice, nor
are they aware of facts which would form a reasonable basis for any such claim,
that: (i) challenges the Company's or its subsidiaries' rights in or to any
Intellectual Property; (ii) challenges the validity or scope of any Intellectual
Property; (iii) any third party has or will be able to establish any rights in
the Intellectual Property, except for the ownership rights of the owners of the
Intellectual Property which is licensed to the Company or the rights of parties
to whom the Company has granted licenses of such Intellectual Property; (iv) the
Intellectual Property infringes or otherwise violates any patent, copyright,
trade secret, trademark or other proprietary right of any third party; or (v)
there is infringement of the Intellectual Property by any third party, which, in
the case of any such claim specified in clauses (i), (ii), (iii), (iv) or (v)
above, singly or in the aggregate, if the subject of an unfavorable decision,
ruling or finding, would have a material adverse effect on the business,
prospects, financial condition or results of operations of the Company and its
subsidiaries, taken as a whole, except that the Company has received notice from
the United States Patent and Trademark Office that its registration of the
trademark "DSL.net" may be removed from the list of supplemental registrations
under certain circumstances.

     (x)  The Company and each of its subsidiaries are insured by insurers of
recognized financial responsibility against such losses and risks and in such
amounts as are prudent and customary in the businesses in which they are
engaged; and neither the Company nor any of its subsidiaries (i) has received
written notice from any insurer or agent of such insurer that substantial
capital improvements or other material expenditures will have to be made in
order to continue such insurance or (ii) has any reason to believe that it will
not be able to renew its existing insurance coverage as and when such coverage
expires or to obtain similar coverage from similar insurers at a cost that would
not have a material adverse effect on the business, prospects, financial
conditions or results of operations of the Company and its subsidiaries, taken
as a whole.

     (y)  No relationship, direct or indirect, exists between or among the
Company or any of its subsidiaries on the one hand, and the directors, officers,
shareholders, customers or suppliers of the Company or any of its subsidiaries
on the other hand, which is required by the Act to be described in the
Registration Statement or the Prospectus which is not so described.

     (z)  There is no (i) significant unfair labor practice complaint,
grievance or arbitration proceeding pending or, to the Company's knowledge,
threatened against the Company or any of its subsidiaries before the National
Labor Relations Board or any state or local labor relations board, (ii) strike,
labor dispute, slowdown or stoppage pending or, to the Company's knowledge,
threatened against the Company or any of its subsidiaries or (iii) union
representation question existing with respect to the employees of the Company
and its subsidiaries, except for such actions specified in clause (i), (ii) or
(iii) above, which, singly or in the aggregate, would not have a material
adverse effect on the business, prospects, financial condition or results of
operations of the Company and its subsidiaries, taken as a whole. To the
Company's knowledge, no collective bargaining organizing activities are taking
place with respect to the Company or any of its subsidiaries.

                                       11
<PAGE>

     (aa) The Company and each of its subsidiaries maintains a system of
internal accounting controls sufficient to provide reasonable assurance that (i)
transactions are executed in accordance with management's general or specific
authorizations; (ii) transactions are recorded as necessary to permit
preparation of financial statements in conformity with generally accepted
accounting principles and to maintain asset accountability; (iii) access to
assets is permitted only in accordance with management's general or specific
authorization; and (iv) the recorded accountability for assets is compared with
the existing assets at reasonable intervals and appropriate action is taken with
respect to any differences.

     (bb) All material tax returns required to be filed by the Company and
each of its subsidiaries in any jurisdiction have been filed, other than those
filings being contested in good faith, and all material taxes, including
withholding taxes, penalties and interest, assessments, fees and other charges
due pursuant to such returns or pursuant to any assessment received by the
Company or any of its subsidiaries have been paid, other than those being
contested in good faith and for which adequate reserves have been provided.

     (cc) The Company has reviewed its operations and any third parties with
which the Company has a material relationship to evaluate the extent to which
the business or operations of the Company will be affected by the Year 2000
Problem. As a result of such review, the Company does not believe that the Year
2000 Problem will have a material adverse effect on the business, prospects,
financial condition or results of operation of the Company and its subsidiaries,
taken as a whole. The "YEAR 2000 PROBLEM" as used herein means any significant
risk that computer hardware or software used in the receipt, transmission,
processing, manipulation, storage, retrieval, retransmission or other
utilization of data or in the operation of mechanical or electrical systems of
any kind will not be able to reliably distinguish dates beginning on January 1,
2000 from dates prior to January 1, 2000.

     (dd) The Company has not at any time during the last five (5) years (i)
made any unlawful contribution to any candidate for foreign office or failed to
disclose fully any contribution in violation of law, or (ii) made any payment to
any federal or state governmental officer or official, or other person charged
with similar public or quasi-public duties, other than payments required or
permitted by the laws of the United States or any jurisdiction thereof.

     (ee) The Company has not taken and will not take, directly or indirectly,
any action designed to or that might reasonably be expected to cause or result
in stabilization or manipulation of the price of the Common Stock to facilitate
the sale or resale of the Shares.

     SECTION 7. Indemnification.  (a) The Company agrees:

          (i)  to indemnify and hold harmless each Underwriter and each person,
if any, who controls any Underwriter within the meaning of the Act, against any
losses, claims, damages or liabilities to which such Underwriter or any such
controlling person may become subject under the Act or otherwise, insofar as
such losses, claims, damages or liabilities (or actions or proceedings in
respect thereof) arise out of or are based upon (i) any untrue statement

                                       12
<PAGE>

or alleged untrue statement of any material fact contained in the Registration
Statement, any Preliminary Prospectus, the Prospectus or any amendment or
supplement thereto, (ii) 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 (iii) any alleged act or failure to act by any
Underwriter in connection with, or relating in any manner to, the Shares or the
offering contemplated hereby, and which is included as part of or referred to in
any loss, claim, damage, liability or action arising out of or based upon
matters covered by clause (i) or (ii) above (provided, that the Company shall
not be liable under this clause (iii) to the extent that it is determined in a
final judgment by a court of competent jurisdiction that such loss, claim,
damage, liability or action resulted directly from any such acts or failures to
act undertaken or omitted to be taken by such Underwriter through its gross
negligence or willful misconduct); provided, however, that the Company will not
be liable in any such case to the extent that any such loss, claim, damage or
liability arises out of or is based upon an untrue statement or alleged untrue
statement, or omission or alleged omission made in the Registration Statement,
any preliminary prospectus, the Prospectus, or such amendment or supplement, in
reliance upon and in conformity with written information furnished to the
Company by or through the Representatives specifically for use in the
preparation thereof; and further provided, however, that the Company will not be
liable to any Underwriter who failed to deliver a Prospectus, as then amended or
supplemental, to the person asserting any claim for any such loss, claim, damage
or liability that arises out of or is based upon an untrue statement or alleged
untrue statement, or omission or alleged omission made in any preliminary
prospectus if such actual or alleged untrue statement or omission was cured in
the Prospectus, as then amended or supplemented.

          (ii) to reimburse each Underwriter and each such controlling person
upon demand for any legal or other out-of-pocket expenses reasonably incurred by
such Underwriter or such controlling person in connection with investigating or
defending any such loss, claim, damage or liability, action or proceeding or in
responding to a subpoena or governmental inquiry related to the offering of the
Shares, whether or not such Underwriter or controlling person is a party to any
action or proceeding. In the event that it is finally judicially determined that
the Underwriters were not entitled to receive payments for legal and other
expenses pursuant to this subparagraph, the Underwriters will promptly return
all sums that had been advanced pursuant hereto.

     (b)  Each Underwriter severally and not jointly will indemnify and hold
harmless the Company, each of its directors, each of its officers who have
signed the Registration Statement and each person, if any, who controls the
Company within the meaning of the Act, against any losses, claims, damages or
liabilities to which the Company or any such director, officer, or controlling
person may become subject under the Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions or proceedings in respect thereof)
arise out of or are based upon (i) any untrue statement or alleged untrue
statement of any material fact contained in the Registration Statement, any
Preliminary Prospectus, the Prospectus or any amendment or supplement thereto,
or (ii) the omission or the alleged omission to state therein 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; and
will reimburse any legal or other expenses reasonably incurred by the Company or
any such director, officer, or controlling person in connection with
investigating or defending any such loss, claim, damage, liability, action or

                                       13
<PAGE>

proceeding; provided, however, that each Underwriter will be liable in each case
to the extent, but only to the extent, that such untrue statement or alleged
untrue statement or omission or alleged omission has been made in the
Registration Statement, any Preliminary Prospectus, the Prospectus or such
amendment or supplement, in reliance upon and in conformity with written
information furnished to the Company by or through the Representatives
specifically for use in the preparation thereof. This indemnity agreement will
be in addition to any liability which such Underwriter may otherwise have.

     (c)  In case any proceeding (including any governmental investigation)
shall be instituted involving any person in respect of which indemnity may be
sought pursuant to this Section 7, such person (the "indemnified party") shall
promptly notify the person against whom such indemnity may be sought (the
"indemnifying party") in writing. No indemnification provided for in Section
7(a) or (b) shall be available to any party who shall fail to give notice as
provided in this Section 7(c) if the party to whom notice was not given was
unaware of the proceeding to which such notice would have related and was
materially prejudiced by the failure to give such notice, but the failure to
give such notice shall not relieve the indemnifying party or parties from any
liability which it or they may have to the indemnified party for contribution or
otherwise than on account of the provisions of Section 7(a) or (b). In case any
such proceeding shall be brought against any indemnified party and it shall
notify the indemnifying party of the commencement thereof, the indemnifying
party shall be entitled to participate therein and, to the extent that it shall
wish, jointly with any other indemnifying party similarly notified, to assume
the defense thereof, with counsel satisfactory to such indemnified party and
shall pay as incurred the fees and disbursements of such counsel related to such
proceeding. In any such proceeding, any indemnified party shall have the right
to retain its own counsel at its own expense. Notwithstanding the foregoing, the
indemnifying party shall pay as incurred (or within 30 days of presentation) the
fees and expenses of the counsel retained by the indemnified party in the event
(i) the indemnifying party and the indemnified party shall have mutually agreed
to the retention of such counsel, (ii) the named parties to any such proceeding
(including any impleaded parties) include both the indemnifying party and the
indemnified party and representation of both parties by the same counsel would
be inappropriate due to actual or potential differing interests between them or
(iii) the indemnifying party shall have failed to assume the defense and employ
counsel acceptable to the indemnified party within a reasonable period of time
after notice of commencement of the action. It is understood that the
indemnifying party shall not, in connection with any proceeding or related
proceedings in the same jurisdiction, be liable for the reasonable fees and
expenses of more than one separate firm for all such indemnified parties. Such
firm shall be designated in writing by you in the case of parties indemnified
pursuant to Section 7(a) and by the Company in the case of parties indemnified
pursuant to Section 7(b). The indemnifying party shall not be liable for any
settlement of any proceeding effected without its written consent but if settled
with such consent or if there be a final judgment for the plaintiff, the
indemnifying party agrees to indemnify the indemnified party from and against
any loss or liability by reason of such settlement or judgment. In addition, the
indemnifying party will not, without the prior written consent of the
indemnified party, settle or compromise or consent to the entry of any judgment
in any pending or threatened claim, action or proceeding of which
indemnification may be sought hereunder (whether or not any indemnified party is
an actual or potential party to such claim, action or proceeding) unless such
settlement, compromise or consent includes an unconditional release of each
indemnified party from all liability arising out of such claim, action or
proceeding.

                                       14
<PAGE>

     (d)  If the indemnification provided for in this Section 7 is unavailable
to or insufficient to hold harmless an indemnified party under Section 7(a), (b)
or (c) above in respect of any losses, claims, damages or liabilities (or
actions or proceedings in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities (or
actions or proceedings in respect thereof) in such proportion as is appropriate
to reflect the relative benefits received by the Company on the one hand and the
Underwriters on the other from the offering of the Shares. If, however, the
allocation provided by the immediately preceding sentence is not permitted by
applicable law then each indemnifying party shall contribute to such amount paid
or payable by such indemnified party in such proportion as is appropriate to
reflect not only such relative benefits but also the relative fault of the
Company on the one hand and the Underwriters on the other in connection with the
statements or omissions which resulted in such losses, claims, damages or
liabilities, (or actions or proceedings in respect thereof), as well as any
other relevant equitable considerations. The relative benefits received by the
Company on the one hand and the Underwriters on the other shall be deemed to be
in the same proportion as the total net proceeds from the offering (before
deducting expenses) received by the Company bear to the total underwriting
discounts and commissions received by the Underwriters, in each case as set
forth in the table on 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 the omission or alleged omission to state
a material fact relates to information supplied by the Company on the one hand
or the Underwriters on the other and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission.

     The Company, and the Underwriters agree that it would not be just and
equitable if contributions pursuant to this Section 7(d) were determined by pro
rata allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to above in this Section 7(d).  The amount
paid or payable by an indemnified party as a result of the losses, claims,
damages or liabilities (or actions or proceedings in respect thereof) referred
to above in this Section 7(d) shall be deemed to include any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim.  Notwithstanding the
provisions of this subsection (d),  (i) no Underwriter shall be required to
contribute any amount in excess of the underwriting discounts and commissions
applicable to the Shares purchased by such Underwriter, and (ii) no person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Act) shall be entitled to contribution from any person who was not guilty of
such fraudulent misrepresentation.  The Underwriters' obligations in this
Section 7(d) to contribute are several in proportion to their respective
underwriting obligations and not joint.

     (e)  In any proceeding relating to the Registration Statement, any
Preliminary Prospectus, the Prospectus or any supplement or amendment thereto,
each party against whom contribution may be sought under this Section 7 hereby
consents to the jurisdiction of any court having jurisdiction over any other
contributing party, agrees that process issuing from such court may be served
upon him or it by any other contributing party and consents to the service of
such process and agrees that any other contributing party may join him or it as
an additional defendant in any such proceeding in which such other contributing
party is a party.

                                       15
<PAGE>

     (f)  Any losses, claims, damages, liabilities or expenses for which an
indemnified party is entitled to indemnification or contribution under this
Section 7 shall be paid by the indemnifying party to the indemnified party as
such losses, claims, damages, liabilities or expenses are incurred. The
indemnity and contribution agreements contained in this Section 7 and the
representations and warranties of the Company set forth in this Agreement shall
remain operative and in full force and effect, regardless of (i) any
investigation made by or on behalf of any Underwriter or any person controlling
any Underwriter, the Company, its directors or officers or any persons
controlling the Company, (ii) acceptance of any Shares and payment therefor
hereunder, and (iii) any termination of this Agreement. A successor to any
Underwriter, or to the Company, its directors or officers, or any person
controlling the Company, shall be entitled to the benefits of the indemnity,
contribution and reimbursement agreements contained in this Section 7.

     (g)  The remedies provided for in this Section 7 are not exclusive and
shall not limit any rights or remedies which may otherwise be available to any
indemnified party at law or in equity.

     SECTION 8.  Conditions of Underwriters' Obligations.  The several
obligations of the Underwriters to purchase the Firm Shares under this Agreement
are subject to the satisfaction of each of the following conditions:

     (a)  All the representations and warranties of the Company contained in
this Agreement shall be true and correct on the Closing Date with the same force
and effect as if made on and as of the Closing Date.

     (b)  If the Company is required to file a Rule 462(b) Registration
Statement after the effectiveness of this Agreement, such Rule 462(b)
Registration Statement shall have become effective by 10:00 P.M., New York City
time, on the date of this Agreement; and no stop order suspending the
effectiveness of the Registration Statement shall have been issued and, to the
Company's knowledge, no proceedings for that purpose shall have been commenced
or shall be pending before or contemplated by the Commission.

     (c)  You shall have received on the Closing Date a certificate dated the
Closing Date, signed by David Struwas and Robert Berlin, in their capacities as
the President and Chief Executive Officer and Chief Financial Officer of the
Company, respectively, confirming the matters set forth in Sections 6(t), 8(a)
and 8(b) (which, with respect to the commencement, pendency and contemplation of
stop order proceedings by the Commission, shall be to their knowledge) and that
the Company has complied with all of the agreements and satisfied all of the
conditions herein contained and required to be complied with or satisfied by the
Company on or prior to the Closing Date.

     (d)  Since the respective dates as of which information is given in the
Prospectus other than as set forth in the Prospectus (exclusive of any
amendments or supplements thereto subsequent to the date of this Agreement), (i)
there shall not have occurred any change or any development involving a
prospective change in the condition, financial or otherwise, or the earnings,
business, management or operations of the Company and its subsidiaries, taken as

a prospective change in the capital stock or in the long-term debt of the
Company or any of its subsidiaries and (iii) neither the Company nor any of its
subsidiaries shall have incurred any liability or obligation, direct or
contingent, the effect of which, in any such case described in clause 8(d)(i),

judgment, makes it impracticable to market the Shares on the terms and in the
manner contemplated in the Prospectus.

in the Prospectus and to own, lease and operate its properties;

          (ii) the Shares have been duly authorized and, when issued and
delivered to the Underwriters against payment therefor as provided by this
Agreement, will be validly issued, fully paid and nonassessable, and the

agreement filed as an exhibit to the Registration Statement;

          (iii)  this Agreement has been duly authorized, executed and
delivered by the Company;

          (iv) the authorized capital stock of the Company conforms as to
legal matters to the description thereof set forth under the caption

          (v)  the Registration Statement has become effective under the Act
and, to such counsel's knowledge, no stop order suspending its effectiveness has
been issued and no proceedings for that purpose are, to such counsel's
knowledge, pending before or contemplated by the Commission;

          (vi) the statements under the captions "Description of Capital Stock"
and "Underwriting" in the Prospectus, insofar as such statements purport to
summarize legal matters present fair summaries of such legal matters, in all
material respects;

          (vii)  the execution, delivery and performance of this Agreement by
the Company, the compliance by the Company with all the provisions hereof and
the consummation of the transactions contemplated hereby will not (A) require

any court or governmental body or agency (except such as may be required under
the Act, the Exchange Act, and the securities or Blue Sky laws of the various

<PAGE>

          (viii)  such counsel does not know of any legal or governmental
proceedings pending or threatened to which the Company or any of its
subsidiaries is a party or to which any of their respective property is subject
that are required to be described in the Registration Statement or the

Registration Statement, there are no contracts, agreements or understandings
between the Company and any person granting such person the right to require the
Company to file a registration statement under the Act with respect to any
securities of the Company or to require the Company to include such securities

contained in the Registration Statement and the Prospectus and although such
counsel need not pass upon, nor assume any responsibility for, the accuracy,
completeness or fairness of the statements contained in the Registration
Statement and the Prospectus and need not make any independent check or
verification thereof, based on such participation no fact has come to the
attention of such counsel that cause such counsel to believe that the
Registration Statement (except for financial statements, financial statement
schedules, and other financial and statistical data included therein, as to
which such counsel need make no statement), at the time it became effective,

fact required to be stated therein or necessary in order to make the statements
therein not misleading, or that the Prospectus (except for financial statements,
financial statement schedules, and other financial and statistical data
included, as to which such counsel need make no statement), as of the date of
such Prospectus or as of the Closing Date, included or includes an untrue
statement of a material fact or omitted or omits to state a material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

above shall be rendered to you at the request of the Company and shall so state
therein.

     (f)  You shall have received on the Closing Date an opinion (satisfactory

          (iii)  the Company is duly qualified and is in good standing as a
foreign corporation authorized to do business in the State of Connecticut; and

present fair summaries of such legal matters, in all material respects;

     (g)  You shall have received on the Closing Date an opinion, dated the

     In giving such opinions, with respect to the matters covered by Section
8(e)(xi), Testa, Hurwitz & Thibeault LLP and Brobeck, Phleger & Harrison LLP may
state that their opinion and belief are based upon their participation in the

     (l)  The Company shall not have failed on or prior to the Closing Date to

     The several obligations of the Underwriters to purchase any Additional
Shares hereunder are subject to the delivery to you on the applicable Option
Closing Date of such documents as you may reasonably request with respect to the
good standing of the Company, the due authorization and issuance of such
Additional Shares and other matters related to the issuance of such Additional
Shares.

     SECTION 9.   Effectiveness of Agreement and Termination.  This Agreement
shall become effective upon the execution and delivery of this Agreement by the
parties hereto.

     This Agreement may be terminated at any time on or prior to the Closing
Date by you by written notice to the Company if any of the following has
occurred:  (i) any outbreak or escalation of hostilities or other national or
international calamity or crisis or change in economic conditions or in the
financial markets of the United States or elsewhere that, in your judgment, is
material and adverse and, in your judgment, makes it impracticable to market the
Shares on the terms and in the manner contemplated in the Prospectus, (ii) the
suspension or material limitation of trading in securities or other instruments
on the New York Stock Exchange, the American Stock Exchange, the Chicago Board
of Options Exchange, the Chicago Mercantile Exchange, the Chicago Board of Trade
or the Nasdaq National Market or limitation on prices for securities or other
instruments on any such exchange or the Nasdaq National Market, (iii) the
suspension of trading of any securities of the Company on any exchange or in the
over-the-counter market, (iv) the enactment, publication, decree or other
promulgation of any federal or state statute, regulation, rule or order of any
court or other governmental authority which in your opinion materially and
adversely affects, or will materially and adversely affect, the business,
prospects, financial condition or results of operations of the Company and its
subsidiaries, taken as a whole, (v) the declaration of a banking moratorium by
either federal or New York State authorities or (vi) the taking of any action by
any federal, state or local government or agency in respect of its monetary or
fiscal affairs which in your opinion has a material adverse effect on the
financial markets in the United States.

     If on the Closing Date or on an Option Closing Date, as the case may be,
any one or more of the Underwriters shall fail or refuse to purchase the Firm
Shares or Additional Shares, as the case may be, which it has or they have
agreed to purchase hereunder on such date and the aggregate number of Firm
Shares or Additional Shares, as the case may be, which such defaulting
Underwriter or Underwriters agreed but failed or refused to purchase is not more
than one-tenth of the total number of Firm Shares or Additional Shares, as the
case may be, to be purchased on such date by all Underwriters, each non-
defaulting Underwriter shall be obligated severally, in the proportion which the
number of Firm Shares set forth opposite its name in Schedule I bears to the
total number of Firm Shares which all the non-defaulting Underwriters have
agreed to purchase, or in such other proportion as you may specify, to purchase
the Firm Shares or Additional Shares, as the case may be, which such defaulting
Underwriter or Underwriters agreed but failed or refused to purchase on such
date; provided that in no event shall the number of Firm Shares or Additional
Shares, as the case may be, which any Underwriter has agreed to purchase
pursuant to Section 2 hereof be increased pursuant to this

                                       20
<PAGE>

Section 9 by an amount in excess of one-ninth of such number of Firm Shares or
Additional Shares, as the case may be, without the written consent of such
Underwriter. If on the Closing Date any Underwriter or Underwriters shall fail
or refuse to purchase Firm Shares and the aggregate number of Firm Shares with
respect to which such default occurs is more than one-tenth of the aggregate
number of Firm Shares to be purchased by all Underwriters and arrangements
satisfactory to you and the Company for purchase of such Firm Shares are not
made within 48 hours after such default, this Agreement will terminate without
liability on the part of any non-defaulting Underwriter and the Company. In any
such case which does not result in termination of this Agreement, either you or
the Company shall have the right to postpone the Closing Date, but in no event
for longer than seven days, in order that the required changes, if any, in the
Registration Statement and the Prospectus or any other documents or arrangements
may be effected. If, on an Option Closing Date, any Underwriter or Underwriters
shall fail or refuse to purchase Additional Shares and the aggregate number of
Additional Shares with respect to which such default occurs is more than one-
tenth of the aggregate number of Additional Shares to be purchased on such date,
the non-defaulting Underwriters shall have the option to (i) terminate their
obligation hereunder to purchase such Additional Shares or (ii) purchase not
less than the number of Additional Shares that such non-defaulting Underwriters
would have been obligated to purchase on such date in the absence of such
default. Any action taken under this paragraph shall not relieve any defaulting
Underwriter from liability in respect of any default of any such Underwriter
under this Agreement.

     SECTION 10. Miscellaneous.  Notices given pursuant to any provision of this
Agreement shall be addressed as follows: (i) if to the Company, to DSL.net,
Inc., 545 Long Wharf Drive, New Haven, Connecticut  06511, Attention: General
Counsel and (ii) if to any Underwriter or to you, to you c/o Deutsche Bank
Securities Inc., One Bankers Trust Plaza, 130 Liberty Street, New York, New York
10006, Attention:  General Counsel, or in any case to such other address as the
person to be notified may have requested in writing.

     The respective indemnities, contribution agreements, representations,
warranties and other statements of the Company and the several Underwriters set
forth in or made pursuant to this Agreement shall remain operative and in full
force and effect, and will survive delivery of and payment for the Shares,
regardless of (i) any investigation, or statement as to the results thereof,
made by or on behalf of any Underwriter, the officers or directors of any
Underwriter, any person controlling any Underwriter, the Company, the officers
or directors of the Company or any person controlling the Company, (ii)
acceptance of the Shares and payment for them hereunder and (iii) termination of
this Agreement.

     If for any reason the Shares are not delivered by or on behalf of the
Company as provided herein (other than as a result of any termination of this
Agreement pursuant to Section 9), the Company agrees to reimburse the several
Underwriters for all out-of-pocket expenses (including the fees and
disbursements of counsel) incurred by them. Notwithstanding any termination of
this Agreement, the Company shall be liable for all expenses which it has agreed
to pay pursuant to Section 5(i) hereof.  The Company also agrees to reimburse
the several Underwriters, their directors and officers and any persons
controlling any of the Underwriters for any and all fees and expenses
(including, without limitation, the fees disbursements of counsel) incurred by
them in connection with enforcing their rights hereunder (including, without
limitation, pursuant to Section 7 hereof).

                                       21
<PAGE>

     Except as otherwise provided, this Agreement has been and is made solely
for the benefit of and shall be binding upon the Company, the Underwriters, the
Underwriters' directors and officers, any controlling persons referred to
herein, the Company's directors and the Company's officers who sign the
Registration Statement and their respective successors and assigns, all as and
to the extent provided in this Agreement, and no other person shall acquire or
have any right under or by virtue of this Agreement.  The term "successors and
assigns" shall not include a purchaser of any of the Shares from any of the
several Underwriters merely because of such purchase.

     This Agreement shall be governed and construed in accordance with the laws
of the State of New York.

     This Agreement may be signed in various counterparts which together shall
constitute one and the same instrument.

     Please confirm that the foregoing correctly sets forth the agreement
between the Company and the several Underwriters.

                                          Very truly yours,

                                          DSL.net, Inc.

with a par value of $.001 per share.


          B.   Rights, Preferences and Restrictions of Preferred Stock.  Of the

("Series B Preferred Stock"), 3,500,000 shares shall be designated as Series C

granted to and imposed on the Series A Preferred Stock, Series B Preferred
Stock, Series C Preferred Stock, Series D Preferred Stock and Series E Preferred
Stock are as set forth below in this Article IV(B).

               1.   Dividend Provisions. The holders of shares of Preferred
                    -------------------
Stock shall be entitled to receive dividends, out of any assets legally
available therefor, prior and in preference to any declaration or payment of any
dividend (payable other than in Common Stock or other securities and rights
convertible into or entitling the holder thereof to receive, directly or
indirectly, additional shares of Common Stock of this corporation) on the Common
Stock of this corporation, at the rate of (i) $.08 per share per annum for the
Series A Preferred Stock, (ii) $.0430768 per share per annum for the Series B
Preferred Stock, (iii) $.2872 per share per annum for the Series C Preferred
Stock, (iv) $.8368 per share for the Series D Preferred Stock and (v) $1.576 per
share per annum for the Series E Preferred Stock (in each case as adjusted for

of the filing of this Amended and Restated Certificate of Incorporation with the
Secretary of State of the State of Delaware), payable when, as, and if declared
by the Board of Directors. Such dividends shall not be cumulative. The holders
of the outstanding Preferred Stock may waive any dividend preference that such
holders shall be entitled to receive under this Section 1 upon the affirmative
vote or written consent of the holders of at least a majority of the Preferred
Stock (voting together as a class, as provided in Section 4(a)) then
outstanding.

               2.   Liquidation Preference.
                    ----------------------

               (a)  In the event of any liquidation, dissolution or winding up
of this corporation, either voluntary or involuntary, the holders of Preferred
Stock shall be entitled to receive, prior and in preference to any distribution
of any of the assets of this corporation to the holders of Common Stock by
reason of their ownership thereof, an amount per share equal to (i) the sum of
$1.00 for each outstanding share of Series A

                                      -2-
<PAGE>

Preferred Stock (the "Original Series A Issue Price"), (ii) the sum of $.53846
for each outstanding share of Series B Preferred Stock (the "Original Series B
Issue Price"), (iii) the sum of $3.59 for each outstanding share of Series C
Preferred Stock (the "Original Series C Issue Price"), (iv) the sum of $10.46
for each outstanding share of Series D Preferred Stock (the "Original Series D
Issue Price") and (v) the sum of $19.70 for each outstanding share of Series E
Preferred Stock (the "Original Series E Issue Price"), plus declared but unpaid
dividends on such shares (subject to adjustment of such fixed dollar amounts for
any stock splits, stock dividends, combinations, recapitalizations or the like,
after the date of the filing of this Amended and Restated Certificate of
Incorporation with the Secretary of State of the State of Delaware). If upon the
occurrence of such event, the assets and funds thus distributed among the
holders of the Preferred Stock shall be insufficient to permit the payment to
such holders of the full aforesaid preferential amounts, then the entire assets
and funds of this corporation legally available for distribution shall be
distributed ratably among the holders of the Preferred Stock in proportion to
the amount of such preferential amounts due on the shares of Preferred Stock
owned by each such holder.

          (b)  Upon completion of the distribution required by subsection (a) of
this Section 2, all of the remaining assets of this corporation available for
distribution to stockholders shall be distributed among the holders of Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, Series D
Preferred Stock, Series E Preferred Stock and Common Stock pro rata based on the
number of shares of Common Stock held by each (assuming full conversion of all
such Preferred Stock, even if not currently convertible).

          (c)  (i)  For purposes of this Section 2, a liquidation, dissolution
or winding up of this corporation shall be deemed to be occasioned by, or to
include, (A) the acquisition of this corporation by another entity by means of
any transaction or series of related transactions (including, without
limitation, any reorganization, merger or consolidation) if, following such
transaction, the holders of the outstanding voting power of the corporation
prior to the transaction cease to hold, directly or indirectly, a majority of
the outstanding voting power of the surviving entity; or (B) a sale of all or
substantially all of the assets of this corporation unless in either case the
holders of Preferred Stock representing a majority of the voting power of the
Preferred Stock (voting together as a class, as provided in Section 4(a)) elect
to the contrary by giving written notice thereof to the corporation at least
three days before the effective date of such event. If such notice is given, the
provisions of Section 3(g) below shall apply.

               (ii) In any of such events, if the consideration received by this
corporation or its stockholders is other than cash or securities, its value will
be deemed its fair market value, as determined in good faith by the Board of
Directors.  Any securities shall be valued as follows:

                    (A)  Securities not subject to investment letter or other
similar restrictions on free marketability covered by (B) below:

                                      -3-
<PAGE>

                         (1)  If traded on a securities exchange or through the
          Nasdaq National Market, the value shall be deemed to be the average of
          the closing prices of the securities on such exchange or system over
          the thirty (30) day period ending three (3) days prior to the closing;

                         (2)  If actively traded over-the-counter, the value
          shall be deemed to be the average of the closing bid or sale prices
          (whichever is applicable) over the thirty (30) day period ending three
          (3) days prior to the closing; and

                         (3)  If there is no active public market, the value
          shall be the fair market value thereof, as mutually determined by this
          corporation and the holders of at least a majority of the voting power
          of all then outstanding shares of Preferred Stock.

                     (B) The method of valuation of securities subject to
     investment letter or other restrictions on free marketability (other than
     restrictions arising solely by virtue of a stockholder's status as an
     affiliate or former affiliate) shall be to make an appropriate discount
     from the market value determined as above in (A) (1), (2) or (3) to reflect
     the approximate fair market value thereof, as mutually determined by this
     corporation and the holders of at least a majority of the voting power of
     all then outstanding shares of Preferred Stock.

               (iii) In the event the requirements of this subsection 2(c) are
     not complied with, this corporation shall forthwith either:

                     (A) cause such closing to be postponed until such time as
     the requirements of this Section 2 have been complied with; or

                     (B) cancel such transaction, in which event the rights,
     preferences and privileges of the holders of the Preferred Stock shall
     revert to and be the same as such rights, preferences and privileges
     existing immediately prior to the date of the first notice referred to in
     subsection 2(c)(iv) hereof.

               (iv)  This corporation shall give each holder of record of
     Preferred Stock written notice of such impending transaction not later than
     twenty (20) days prior to the stockholders' meeting called to approve such
     transaction, or twenty (20) days prior to the closing of such transaction,
     whichever is earlier, and shall also notify such holders in writing of the
     final approval of such transaction. The first of such notices shall
     describe the material terms and conditions of the impending transaction and
     the provisions of this Section 2, and this corporation shall thereafter
     give such holders prompt notice of any material changes. The transaction
     shall in no event take place sooner than twenty (20) days after this
     corporation has given the first notice provided for herein or sooner than
     ten (10) days after this corporation has given notice of any material
     changes provided for herein; provided, however, that such periods may be
     shortened upon the written

                                      -4-
<PAGE>

     consent of the holders of Preferred Stock that are entitled to such notice
     rights or similar notice rights and that represent at least a majority of
     the voting power of all then outstanding shares of such Preferred Stock.

                    ----------------

                    (i)   Each share of Series A Preferred Stock shall be

                    --------------------
     automatically be converted into shares of Common Stock at the applicable
     Conversion Price at the time in effect for such series of Preferred Stock
     immediately upon the earlier of (i) this corporation's sale of its Common
     Stock in a firm commitment underwritten public offering pursuant to a
     registration statement under the Securities Act of 1933, as amended, the
     public offering price of which was not less than $7.50 per share (as
     adjusted for any stock splits, stock dividends, recapitalizations and the
     like after the date of the filing of this Amended and Restated Certificate
     of Incorporation with the Secretary of State of the State of Delaware),
     resulting in aggregate net proceeds to this corporation of at least
     $30,000,000 or (ii) the date specified by written consent or agreement of
     the holders of a majority of the then outstanding shares of Series A
     Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, Series

     provided in Section 4(a)).

               (c)  Mechanics of Conversion. Before any holder of Preferred
                    -----------------------
     Stock shall be entitled to convert the same into shares of Common Stock, he
     or she shall surrender the certificate or certificates therefor, duly
     endorsed, at the office of this corporation or of any transfer agent for
     such Preferred Stock, and shall give written notice to this corporation at
     its principal corporate office, of the election to convert the same and
     shall state therein the name or names in which the certificate or
     certificates for shares of Common Stock are to be issued. This

                                      -6-
<PAGE>

     corporation shall, as soon as practicable thereafter, issue and deliver at
     such office to such holder of Preferred Stock, or to the nominee or
     nominees of such holder, a certificate or certificates for the number of
     shares of Common Stock to which such holder shall be entitled as aforesaid.
     Such conversion shall be deemed to have been made immediately prior to the
     close of business on the date of such surrender of the shares of Preferred
     Stock to be converted, and the person or persons entitled to receive the
     shares of Common Stock issuable upon such conversion shall be treated for
     all purposes as the record holder or holders of such shares of Common Stock
     as of such date. If the conversion is in connection with an underwritten
     offering of securities registered pursuant to the Securities Act of 1933,
     the conversion may, at the option of any holder tendering Preferred Stock
     for conversion, be conditioned upon the closing with the underwriters of
     the sale of securities pursuant to such offering, in which event the
     persons entitled to receive the Common Stock upon conversion of the
     Preferred Stock shall not be deemed to have converted such Preferred Stock
     until immediately prior to the closing of such sale of securities.

               (d)  Conversion Price Adjustments of Preferred Stock for Certain
                    -----------------------------------------------------------
     Dilutive Issuances, Splits and Combinations. The Conversion Price of the
     -------------------------------------------
     Series A Preferred Stock, the Conversion Price of the Series B Preferred
     Stock, the Conversion Price of the Series C Preferred Stock, the Conversion
     Price of the Series D Preferred Stock and the Conversion Price of the
     Series E Preferred Stock shall be subject to adjustment from time to time
     as follows:

                    (i)  (A)  If this corporation shall issue, after July 21,
     1999 (the "Purchase Date"), any Additional Stock (as defined below) without
     consideration or for a consideration per share less than the applicable
     Conversion Price for the Series A Preferred Stock, Series B Preferred
     Stock, Series C Preferred Stock, Series D Preferred Stock or Series E
     Preferred Stock in effect immediately prior to the issuance of such
     Additional Stock, the applicable Conversion Price for the Series A
     Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, Series
     D Preferred Stock or Series E Preferred Stock, as the case may be, in
     effect immediately prior to each such issuance shall forthwith (except as
     otherwise provided in this clause (i)) be adjusted to a price determined by
     multiplying such Conversion Price by a fraction, the numerator of which
     shall be the number of shares of such series of Preferred Stock outstanding
     immediately prior to such issuance plus the number of shares of capital
     stock that the aggregate consideration received by this corporation for
     such issuance would purchase at such Conversion Price and the denominator
     of which shall be the number of shares of such series of Preferred Stock
     outstanding immediately prior to such issuance plus the number of shares of
     such Additional Stock.

                         (B)  No adjustment of the applicable Conversion Price
     for the Series A Preferred Stock, Series B Preferred Stock, Series C
     Preferred Stock, Series D Preferred Stock or Series E Preferred Stock shall
     be made in an amount less than one cent per share, provided that any
     adjustments that are not

                                      -7-
<PAGE>

     required to be made by reason of this sentence shall be carried forward and
     shall be either taken into account in any subsequent adjustment made prior
     to three (3) years from the date of the event giving rise to the adjustment
     being carried forward, or shall be made at the end of three (3) years from
     the date of the event giving rise to the adjustment being carried forward.
     Except to the limited extent provided for in subsections (E)(3) and (E)(4),
     no adjustment of such Conversion Price pursuant to this subsection 3(d)(i)
     shall have the effect of increasing the Conversion Price above the
     Conversion Price in effect immediately prior to such adjustment.

                         (C)  In the case of the issuance of Common Stock for
     cash, the consideration shall be deemed to be the amount of cash paid
     therefor before deducting any reasonable discounts, commissions or other
     expenses allowed, paid or incurred by this corporation for any underwriting
     or otherwise in connection with the issuance and sale thereof.

                         (D)  In the case of the issuance of the Common Stock
     for a consideration in whole or in part other than cash, the consideration
     other than cash shall be deemed to be the fair value thereof as determined
     in good faith by the Board of Directors for this purpose, irrespective of
     any accounting treatment.

                         (E)  In the case of the issuance (whether before, on or
     after the applicable Purchase Date) of options to purchase or rights to
     subscribe for Common Stock, securities by their terms convertible into or
     exchangeable for Common Stock or options to purchase or rights to subscribe
     for such convertible or exchangeable securities, the following provisions
     shall apply for all purposes of this subsection 3(d)(i) and subsection
     3(d)(ii):

                              (1)  The aggregate maximum number of shares of
          Common Stock deliverable upon exercise (assuming the satisfaction of
          any conditions to exercisability, including without limitation, the
          passage of time, but without taking into account potential
          antidilution adjustments) of such options to purchase or rights to
          subscribe for Common Stock shall be deemed to have been issued at the
          time such options or rights were issued and for a consideration equal
          to the consideration (determined in the manner provided in subsections
          3(d)(i)(C) and (d)(i)(D)), if any, received by this corporation upon
          the issuance of such options or rights plus the minimum exercise price
          provided in such options or rights (without taking into account
          potential antidilution adjustments) for the Common Stock covered
          thereby.

                              (2)  The aggregate maximum number of shares of
          Common Stock deliverable upon conversion of, or in exchange for, any
          such convertible or exchangeable securities or upon the exercise of
          options to purchase or rights to subscribe for such convertible or
          exchangeable securities and subsequent conversion or exchange thereof
          shall be deemed

          to have been issued at the time such securities were issued or such
          options or rights were issued and for a consideration equal to the
          consideration, if any, received by this corporation for any such
          securities and related options or rights (excluding any cash received
          on account of accrued interest or accrued dividends), plus the minimum
          additional consideration, if any, to be received by this corporation
          (without taking into account potential antidilution adjustments) upon
          the conversion or exchange of such securities or the exercise of any
          related options or rights (the consideration in each case to be
          determined in the manner provided in subsections 3(d)(i)(C) and
          (d)(i)(D)).

                              (3)  In the event of any change in the number of
          shares of Common Stock deliverable or in the consideration payable to
          this corporation upon exercise of such options or rights or upon
          conversion of or in exchange for such convertible or exchangeable
          securities, including, but not limited to, a change resulting from the
          antidilution provisions thereof, the applicable Conversion Price of
          each series of Preferred Stock, to the extent in any way affected by
          or computed using such options, rights or securities, shall be
          recomputed to reflect such change, but no further adjustment shall be
          made for the actual issuance of Common Stock or any payment of such
          consideration upon the exercise of any such options or rights or the
          conversion or exchange of such securities.

                              (4)  Upon the expiration of any such options or
          rights, the termination of any such rights to convert or exchange or
          the expiration of any options or rights related to such convertible or
          exchangeable securities, the applicable Conversion Price of each
          series of Preferred Stock, to the extent in any way affected by or
          computed using such options, rights or securities or options or rights
          related to such securities, shall be recomputed to reflect the
          issuance of only the number of shares of Common Stock (and convertible
          or exchangeable securities that remain in effect) actually issued upon
          the exercise of such options or rights, upon the conversion or
          exchange of such securities or upon the exercise of the options or
          rights related to such securities.

                              (5)  The number of shares of Common Stock deemed
          issued and the consideration deemed paid therefor pursuant to
          subsections 3(d)(i)(E)(1) and (2) shall be appropriately adjusted to
          reflect any change, termination or expiration of the type described in
          either subsection 3(d)(i)(E)(3) or (4).

                    (ii) "Additional Stock" shall mean any shares of Common
     Stock issued (or deemed to have been issued pursuant to subsection
     3(d)(i)(E)) by this corporation after the Purchase Date, other than:

     date of the filing of this Amended and Restated Certificate of
     Incorporation with the Secretary of State of the State of Delaware) of
     Common Stock (or options to purchase or rights to subscribe for Common
     Stock, securities by their terms convertible into or exchangeable for
     Common Stock, or options to purchase or rights to subscribe for such
     convertible or exchangeable securities) issuable, or issued to employees,

     purposes) of this corporation directly or pursuant to a stock option plan,
     restricted stock plan or other stock-based employee compensation plan
     approved by the Board of Directors of this corporation, provided, however,

     Preferred Stock in exchange for shares of Series A Preferred Stock and

     shares of Series A Preferred Stock, Series B Preferred Stock, Series C
     Preferred Stock, Series D Preferred Stock, or Series E Preferred Stock.

                    (iii) In the event this corporation shall at any time or
     from time to time after the Purchase Date fix a record date for the
     effectuation of a split or subdivision of the outstanding shares of Common
     Stock or the determination of holders of Common Stock entitled to receive a
     dividend or other distribution payable in additional shares of Common Stock
     or other securities or rights convertible into, or entitling the holder
     thereof to receive directly or indirectly,

                                      -10-
<PAGE>

     additional shares of Common Stock (hereinafter referred to as "Common Stock
     Equivalents") without payment of any consideration by such holder for the
     additional shares of Common Stock or the Common Stock Equivalents
     (including the additional shares of Common Stock issuable upon conversion
     or exercise thereof), then, as of such record date (or the date of such
     dividend distribution, split or subdivision if no record date is fixed),
     the applicable Conversion Price of each series of Preferred Stock shall be
     appropriately decreased so that the number of shares of Common Stock
     issuable on conversion of each share of such series shall be increased in
     proportion to such increase of the aggregate of shares of Common Stock
     outstanding and those issuable with respect to such Common Stock
     Equivalents (with the number of shares issuable with respect to Common
     Stock Equivalents determined in the manner provided for deemed issuances in
     subsection 3(d)(i)(E)).

                    (iv) If the number of shares of Common Stock outstanding at
     any time after the Purchase Date is decreased by a combination of the
     outstanding shares of Common Stock, then, following the record date of such
     combination, the applicable Conversion Price of each series of Preferred
     Stock shall be appropriately increased so that the number of shares of
     Common Stock issuable on conversion of each share of such series shall be
     decreased in proportion to such decrease in outstanding shares.

               (e)  Other Distributions. In the event this corporation shall
                    -------------------
     declare a distribution payable in securities of other persons, evidences of
     indebtedness issued by this corporation or other persons, assets (excluding
     cash dividends) or options or rights not referred to in subsection
     3(d)(iii), then, in each such case for the purpose of this subsection 3(e),
     the holders of the Preferred Stock shall be entitled to a proportionate
     share of any such distribution as though they were the holders of the
     number of shares of Common Stock of this corporation into which their
     shares of Preferred Stock are convertible as of the record date fixed for
     the determination of the holders of Common Stock of this corporation
     entitled to receive such distribution or the date of such distribution if
     no record date is fixed.

               (f)  Recapitalizations. If at any time or from time to time there
                    -----------------
     shall be a recapitalization of the Common Stock (other than a subdivision,
     combination or merger or sale of assets transaction provided for elsewhere
     in this Section 3 or in Section 2), provision shall be made so that the
     holders of the Preferred Stock shall thereafter be entitled to receive upon
     conversion of the Preferred Stock the number of shares of stock or other
     securities or property of the corporation or otherwise, to which a holder
     of Common Stock deliverable upon conversion of such Preferred Stock would
     have been entitled on such recapitalization. In any such case, appropriate
     adjustment shall be made in the application of the provisions of this
     Section 3 with respect to the rights of the holders of the Preferred Stock
     after the recapitalization to the end that the provisions of this Section 3
     (including adjustment of the Conversion Price then in effect and the number
     of shares purchasable upon conversion of the Preferred

                                      -11-
<PAGE>

     Stock) shall be applicable after that event as nearly equivalent as may be
     practicable.

               (g)  Adjustment for Merger or Reorganization.  In case of any
                    ---------------------------------------
     consolidation or merger of the corporation with or into another corporation
     or the sale of all or substantially all of the assets of the corporation to
     another corporation (other than a consolidation, merger, or sale that is
     treated as a liquidation under Section 2 (c) above), each share of
     Preferred Stock shall thereafter be convertible into the number of shares
     of stock or other securities or property to which a holder of the number of
     shares of Common Stock of the corporation deliverable upon conversion of
     such Preferred Stock would have been entitled upon such consolidation,
     merger or conveyance.

               (h)  No Impairment. This corporation will not, by amendment of
                    -------------
     its certificate of incorporation or through any reorganization,
     recapitalization, transfer of assets, consolidation, merger, dissolution,
     issue or sale of securities or any other voluntary action, avoid or seek to
     avoid the observance or performance of any of the terms to be observed or
     performed hereunder by this corporation, but will at all times in good
     faith assist in the carrying out of all the provisions of this Section 3
     and in the taking of all such action as may be necessary or appropriate in
     order to protect the Conversion Rights of the holders of the Preferred
     Stock against impairment.

               (i)  No Fractional Shares and Certificate as to Adjustments.
                    ------------------------------------------------------

                    (i)  No fractional shares shall be issued upon the
     conversion of any share or shares of the Preferred Stock, and the number of
     shares of Common Stock to be issued shall be rounded up to the nearest
     whole share, determined on the basis of the total number of shares of
     Preferred Stock the holder is at the time converting into Common Stock and
     the number of shares of Common Stock issuable upon such aggregate
     conversion.

                    (ii) Upon the occurrence of each adjustment or readjustment
     of the applicable Conversion Price for each series of Preferred Stock
     pursuant to this Section 3, this corporation, at its expense, shall
     promptly compute such adjustment or readjustment in accordance with the
     terms hereof and prepare and furnish to each holder of Preferred Stock a
     certificate setting forth such adjustment or readjustment and showing in
     detail the facts upon which such adjustment or readjustment is based. This
     corporation shall, upon the written request at any time of any holder of
     Preferred Stock, furnish or cause to be furnished to such holder a like
     certificate setting forth (A) such adjustment and readjustment, (B) the
     applicable Conversion Price for such series of Preferred Stock at the time
     in effect, and (C) the number of shares of Common Stock and the amount, if
     any, of other property that at the time would be received upon the
     conversion of a share of such series of Preferred Stock.

          (j)  Notices of Record Date.  In the event of any taking by this
               ----------------------
corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend (other than a cash dividend) or other distribution, any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property, or to receive any other right, this
corporation shall mail to each holder of Preferred Stock, at least ten (10) days
prior to the date specified therein, a notice specifying the date on which any
such record is to be taken for the purpose of such dividend, distribution or
right, and the amount and character of such dividend, distribution or right.

          (k)  Reservation of Stock Issuable Upon Conversion.  This corporation
               ---------------------------------------------
shall at all times reserve and keep available out of its authorized but unissued
shares of Common Stock, solely for the purpose of effecting the conversion of
the shares of the Preferred Stock, such number of its shares of Common Stock as
shall from time to time be sufficient to effect the conversion of all
outstanding shares of the Preferred Stock; and if at any time the number of
authorized but unissued shares of Common Stock shall not be sufficient to effect
the conversion of all then outstanding shares of the Preferred Stock, in
addition to such other remedies as shall be available to the holder of such
Preferred Stock, this corporation will take such corporate action as may, in the
opinion of its counsel, be necessary to increase its authorized but unissued
shares of Common Stock to such number of shares as shall be sufficient for such
purposes, including, without limitation, engaging in best efforts to obtain the
requisite shareholder approval of any necessary amendment to this its
certificate of incorporation.

          (l)  Notices. Any notice required by the provisions of this Section 3
               -------
to be given to the holders of shares of Preferred Stock shall be deemed given if
deposited in the United States mail, postage prepaid, and addressed to each
holder of record at his address appearing on the books of this corporation.

stockholders, (ii) for acts or omissions not in good faith or that involve
intentional misconduct or a knowing violation of law, (iii) under Section 174 of

possibility that these interests might be best served by the continued
independence of this corporation;

          (B) whether the proposed transaction might violate federal or
state laws;

          (C) not only the consideration being offered in the proposed

stock of this corporation over a period of years, the estimated price that might
be achieved in a negotiated sale of this corporation as a whole or in part or
through orderly liquidation, the premiums over

Directors may determine.

authorized shares of Preferred Stock set forth in Article IV or (ii) amend or
repeal, or adopt any provision inconsistent with, Articles III, V, VI, VII, IX,

                                  ARTICLE XII

     2.4  Voting List.  The officer who has charge of the stock ledger of the
          -----------
Corporation shall prepare and make, at least ten days before every meeting of
stockholders, a complete list of the stockholders entitled to vote at the

<PAGE>

presumptively determine the identity of the stockholders entitled to vote at the

     2.5  Special Stockholders Meetings.  Special meetings of stockholders may

          ------
in person or represented by proxy, shall constitute a quorum at all meetings of
the stockholders for the transaction of business except as otherwise provided by

brokers which such brokers are prohibited from voting (pursuant to their
discretionary authority on behalf of beneficial owners of such shares who have
not submitted a proxy with respect to such shares) on some or all of the matters
before the stockholders, but which shares would otherwise be entitled to vote at
the meeting ("Broker Non-Votes") shall be counted, for the purpose of
determining the presence or absence of a quorum, both (a) toward the total
voting power of the shares of capital stock of the Corporation and (b) as being
represented by proxy. If a quorum has been established for the purpose of
conducting the meeting, a quorum shall be deemed to be present for the purpose
of all votes to be conducted at such meeting, provided that where a separate
vote by a class or classes, or series thereof, is required, a majority of the
voting power of the shares of such class or classes, or series, present in
person or represented by proxy shall constitute a quorum entitled to take action
with respect to that vote on that matter. If, however, such quorum shall not be
present or represented at any meeting of the stockholders, the chairman of the
meeting or the stockholders holding a majority of the voting power of the shares
of stock entitled to vote thereat, present in person or represented by proxy,
shall have power to adjourn the meeting from time to time, without notice other
than announcement at the meeting, until a quorum shall be present or
represented. At such adjourned meeting at which a quorum shall be present or
represented, any business may be transacted which might have been transacted at
the meeting as originally notified. If the adjournment is for more than thirty
days, or if after the adjournment a new record date is fixed for the adjourned
meeting, a notice of the adjourned meeting shall be given to each stockholder of
record entitled to vote at the meeting.

     2.9  Controlling Vote.  When a quorum is present at any meeting, the
          ----------------
vote of the holders of a majority of the voting power present in person or
represented by proxy shall decide any question brought before such meeting,
unless the question is one upon which by express

                                      -2-
<PAGE>

provision of a statute, the Certificate of Incorporation or these by-laws a
different vote is required, in which case such express provision shall govern
and control the decision of such question. Any election of directors by the
stockholders shall be determined by a plurality of the votes cast by the
stockholders entitled to vote at such election, except as otherwise provided by
the Certificate of Incorporation. For the purposes of this Section 2.9, Broker
Non-Votes represented at the meeting but not permitted to vote on a particular
matter shall not be counted, with respect to the vote on such matter, in the
number of (a) votes cast, (b) votes cast affirmatively, or (c) votes cast
negatively.

     2.10  Voting and Proxies.  At any meeting of the stockholders, each
           ------------------
stockholder shall have one vote for each share of stock entitled to vote at such
meeting held of record by such stockholder and a proportionate vote for each
fractional share so held, unless otherwise provided in the Certificate of
Incorporation.  Each stockholder of record entitled to vote at a meeting of
stockholders, or to express consent or dissent to corporate action in writing
without a meeting (to the extent not otherwise prohibited by the Certificate of
Incorporation or these by-laws), may vote or express such consent or dissent in
person or may authorize another person or persons to vote or act for such
stockholder by written proxy executed by such stockholder or his or her
authorized agent or by a transmission permitted by law and delivered to the
secretary of the Corporation.  No such proxy shall be voted or acted upon after
three years from the date of its execution, unless the proxy expressly provides
for a longer period.  Any copy, facsimile telecommunication or other reliable
reproduction of the writing or transmission created pursuant to this Section
2.10 may be substituted or used in lieu of the original writing or transmission
for any and all purposes for which the original writing or transmission could be
used, provided that such copy, facsimile telecommunication or reproduction shall
be a complete reproduction of the entire original writing or transmission.

     All voting, including on the election of directors but excepting where
otherwise required by law or the Certificate of Incorporation, may take place
via a voice vote.  Any vote not taken by voice shall be taken by ballots, each
of which shall state the name of the stockholder or proxy voting and such other
information as may be required under the procedure established for the meeting.

           -------------------------------

                                      -13-
<PAGE>

connection therewith, notwithstanding that such person has not been successful
(on the merits or otherwise) on any other claim, issue or matter in any such
claim, action, suit or proceeding.

     8.4  Authorization.  Any indemnification under Sections 8.1 and 8.2 (unless
          -------------
ordered by a court) shall be made by the Corporation only as authorized in the
specific case upon a determination that indemnification of the present or former
director, officer, employee or agent is proper in the circumstances because such
person has met the applicable standard of conduct set forth in Sections 8.1 and
8.2.  Such determination shall be made, with respect to a person who is a
director or officer at the time of such determination, (a) by a majority vote of
the directors who are or were not parties to such action, suit or proceeding,
even though less than a quorum, or (b) by a committee of such directors
designated by majority vote of such directors, even though less than a quorum,
or (c) if there are no such directors, or if such directors so direct, by
independent legal counsel in a written opinion, or (d) by the stockholders.

     8.5  Advanced Reimbursement.  Expenses (including attorneys' fees and
          ----------------------
disbursements, inclusive of any appeal) incurred by an officer or director of
the Corporation in defending any pending or threatened civil, criminal,
administrative or investigative action, suit or proceeding shall be paid by the
Corporation in advance of the final disposition of such action, suit or
proceeding upon receipt of an undertaking by or on behalf of the director or
officer to repay such amount if it shall ultimately be determined that such
person is not entitled to be indemnified by the Corporation as authorized in
this, or granted pursuant to, Section 8.  Such expenses (including attorneys'
fees) incurred by former directors and officers or other employees or agents of
the Corporation may be so paid upon such terms and conditions, if any, as the
Board of Directors deems appropriate.

     8.6  Indemnification No Exclusive.  The indemnification and advancement of
          ----------------------------
expenses provided by, or granted pursuant to, this Section 8 shall not be deemed
exclusive of any other rights to which those indemnified may be entitled under
any statute, rule of law, provision of the Certificate of Incorporation, as it
may be amended, By-law, agreement, vote of stockholders or disinterested
directors, or otherwise, both as to action in such person's official capacity
and as to action in another capacity while holding such office, and shall
continue as to a person who has ceased to be a director, officer, employee or
agent and shall inure to the benefit of the heirs, executors and administrators
of such a person.  Where such other provision provides broader rights of
indemnification than these by-laws, said other provision shall control.

     8.7  Indemnification of Employees and Agents.  The Corporation may, to the
          ---------------------------------------
extent authorized from time to time by the Board of Directors, provide rights to
indemnification and to the advancement of expenses to employees and agents of
the Corporation, and to such employees and agents serving at the request of the
Corporation as a director, partner, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise or non-profit
entity, similar to those conferred in this Section 8 to directors and officers
of the Corporation.

     8.8  Insurance.  The Corporation shall have power to purchase and maintain
          ---------
insurance on behalf of any person who is or was a director, officer, employee or
agent of the Corporation, or is or was serving at the request of the Corporation
as a director, partner, officer, employee agent of another corporation,
partnership, joint venture, trust or other enterprise or

                                      -14-
<PAGE>

non-profit entity against any liability asserted against such person and
incurred by such person in any such capacity, or arising out of such person's
status as such, whether or not the Corporation would have the power to indemnify
him against such liability under the provisions of this Section 8.

9.   AMENDMENTS.
     ----------

     9.1  By the Board of Directors.  Except as is otherwise set forth in these
          -------------------------
by-laws, these by-laws may be altered, amended or repealed, or new by-laws may

     RE:  Registration Statement on Form S-1 (No. 333-80141)

Ladies and Gentlemen:

     We are acting as counsel for DSL.net, Inc., a Delaware corporation (the
"Company"), in connection with the issuance and sale by the Company of up to
 -------
10,968,000 shares (the "Shares") of Common Stock, par value $.0005 per share, of
                        ------
the Company pursuant to the Company's Registration Statement on Form S-1 (No.
333-80141) which has been filed with the Securities and Exchange Commission (the
"Registration Statement").
 ----------------------

     We have examined such documents, records and matters of law as we have
deemed necessary for the purposes of this opinion, and based thereupon we are of
the opinion that the Shares, when issued and paid for in accordance with the
terms described in the Registration Statement, will be validly issued, fully
paid and nonassessable.

     We hereby consent to the filing of this opinion as Exhibit 5.01 to the
Registration Statement and to the reference to our firm in the Prospectus under
the caption "Legal Matters."


                                         Very truly yours,


                                         TESTA, HURWITZ & THIBEAULT, LLP

<PAGE>

                                                                   Exhibit 10.01


                                 DSL.net, Inc.

                     AMENDED AND RESTATED 1999 STOCK PLAN

           February 19, 1999, as amended and restated as of ________


SECTION 1.  Purpose.
- ---------   -------

     The purpose of the Amended and Restated 1999 Stock Plan (the "Plan") is to
secure for DSL.net, Inc., (the "Company"), its parent (if any) and any
subsidiaries of the Company (collectively the "Related Corporations") the
benefits arising from capital stock ownership by those employees, directors,
officers and consultants of the Company and any Related Corporations who will be
responsible for the Company's future growth and continued success.

     The Plan will provide a means whereby (a)  employees of the Company and any
Related Corporations may purchase stock in the Company pursuant to options which
qualify as "incentive stock options" ("Incentive Stock Options") under Section
422 of the Internal Revenue Code of 1986, as amended (the "Code"), (b)
directors, employees and consultants of the Company and any Related Corporations
may purchase stock in the Company pursuant to options granted hereunder which do
not qualify as Incentive Stock Options ("Non-Qualified Options"); (c) directors,
employees and consultants of the Company and any Related Corporations may be
awarded stock in the Company ("Awards"); (d) directors, employees and
consultants of the Company and any Related Corporations may receive stock
appreciation rights ("SARs"); and (e) directors, employees and consultants of
the Company and any Related Corporations may make direct purchases of stock in
the Company ("Purchases").  Both Incentive Stock Options and Non-Qualified
Options are referred to hereafter individually as an "Option" and collectively
as "Options."  As used herein, the terms "parent" and "subsidiary" mean "parent
corporation" and "subsidiary corporation" as those terms are defined in Section
424 of the Code.  Options, Awards, SARs and Purchases are referred to hereafter
individually as a "Plan Benefit" and collectively as "Plan Benefits."
Directors, employees and consultants of the Company and any Related Corporations
are referred to herein as "Participants."

SECTION 2.  Administration.
- ---------   --------------

     2.1    Board of Directors and the Committee.  The Plan will be administered
            ------------------------------------
by the Board of Directors of the Company whose construction and interpretation
of the terms and provisions hereof shall be final and conclusive.  Any director
to whom a Plan Benefit is awarded shall be ineligible to vote upon his or her
Plan Benefit, but Plan Benefits may be granted any such director by a vote of
the remainder of the directors, except as limited below.  The Board of Directors
may in its sole discretion grant Options, issue shares upon exercise of such
Options, grant Awards, grant SARs and approve Purchases, all as provided in the
Plan.  The Board of Directors shall have authority, subject to the express
provisions of the Plan, to construe the Plan and its related agreements, to
prescribe, amend and rescind rules and regulations relating to the Plan, to
determine the terms and provisions of the respective Option, Award, SAR and
Purchase
<PAGE>

                                      -2-

agreements, which need not be identical, and to make all other determinations in
the judgment of the Board of Directors necessary or desirable for the
administration of the Plan. The Board of Directors may correct any defect or
supply any omission or reconcile any inconsistency in the Plan or in any related
agreement in the manner and to the extent it shall deem expedient to carry the
Plan into effect and it shall be the sole and final judge of such expediency. No
director shall be liable for any action or determination made in good faith. The
Board of Directors may delegate to the President or Chief Executive Officer of
the Company the power to grant options to non-officers in accordance with
written guidelines approved by the Board of Directors. In addition, the Board of
Directors may delegate any or all of its powers under the Plan to a Compensation
Committee or other Committee (the "Committee") appointed by the Board of
Directors consisting of at least two members of the Board of Directors. If the
Company has a class of stock registered pursuant to Section 12 of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), then members of the
Committee shall at all times be: (i) "outside directors" as such term is defined
in Treas. Reg. (S) 1.162-27(e)(3) (or any successor regulation); and (ii) "non-
employee directors" within the meaning of Rule 16b-3 (or any successor rule)
under the Exchange Act, as such terms are interpreted from time to time;
provided, however that if the members of the Committee do not meet the
requirements set forth in (ii) above, then all decisions and acts of the
Committee shall be subject to and effective upon the approval of the Board of
Directors. If a Committee meeting the requirements of (i) and (ii) above is so
appointed, all references to the Board of Directors herein shall mean and relate
to such Committee, unless the context otherwise requires; provided, however,
                                                          -----------------
that if a Committee is appointed that does not meet the requirements of and (ii)
above, then all decisions and acts of the Committee shall be subject to and
effective upon the approval of the Board of Directors.

     2.2  Compliance with Section 162(m) of the Code.  Section 162(m) of the
          ------------------------------------------
Code, added by the Omnibus Budget Reconciliation Act of 1993, generally limits
the tax deductibility to publicly held companies of compensation in excess of
$1,000,000 paid to certain "covered employees" ("Covered Employees").  If the
Company is subject to Section 162(m) of the Code, it is the Company's intention
to preserve the deductibility of such compensation to the extent it is
reasonably practicable and to the extent it is consistent with the Company's
compensation objectives.  For purposes of this Plan, Covered Employees of the
Company shall be those employees of the Company described in Section 162(m)(3)
of the Code.

SECTION 3.  Eligibility.
- ---------   -----------

     3.1  Incentive Stock Options.  Participants who are employees shall be
          -----------------------
eligible to receive Incentive Stock Options pursuant to the Plan; provided that
no person shall be granted any Incentive Stock Option under the Plan who, at the
time such Option is granted, owns, directly or indirectly, Common Stock of the
Company possessing more than 10% of the total combined voting power of all
classes of stock of the Company or of its Related Corporations, unless the
requirements of Section 6.6(b) hereof are satisfied.  In determining whether
this 10% threshold has been reached, the stock attribution rules of Section
424(d) of the Code shall apply.  Directors who are not regular employees are not
eligible to receive Incentive Stock Options.
<PAGE>

                                      -3-

     3.2  Non-Qualified Options, Awards, SARs and Purchases.  Non-Qualified
          -------------------------------------------------
Options, Awards, SARs and authorizations to make Purchases may be granted to any
Participant.

     3.3  Generally.  The Board of Directors may take into consideration a
          ---------
Participant's individual circumstances in determining whether to grant an
Incentive Stock Option, a Non-Qualified Option, an Award or an SAR or to approve
a Purchase.  Granting of any Option, Award or SAR or approval of any Purchase
for any individual shall neither entitle that individual to, nor disqualify that
individual from, participation in any other grant of Plan Benefits.

SECTION 4.  Stock Subject to Plan.
- ---------   ---------------------

     Subject to adjustment as provided in Sections 10 and 11 hereof, the stock
to be offered under the Plan shall consist of shares of the Company's Common
Stock, par value $.0005 per share, and the maximum number of shares of stock
which will be reserved for issuance, and in respect of which Plan Benefits may
be granted pursuant to the provisions of the Plan, shall not exceed in the
aggregate 12,364,200 shares.  Such shares may be authorized and unissued shares
or may be treasury shares.  If an Option or SAR granted hereunder shall expire
or terminate for any reason without having been exercised in full, or if the
Company shall reacquire any unvested shares issued pursuant to Awards or
Purchases, the unpurchased shares subject thereto and any unvested shares so
reacquired shall again be available for subsequent grants of Plan Benefits under
the Plan.  Stock issued pursuant to the Plan may be subject to such restrictions
on transfer, repurchase rights or other restrictions as shall be determined by
the Board of Directors.

SECTION 5.  Granting of Options, Awards and SARs and Approvals of Purchases.
- ---------   ---------------------------------------------------------------

     Options, Awards and SARs may be granted and Purchases may be approved under
the Plan at any time after February 19, 1999 and prior to February 19, 2009.
The date of grant of an Option, Award or SAR or approval of a Purchase under the
Plan will be the date specified by the Board of Directors at the time the Board
of Directors grants such Option, Award or SAR or approves such Purchase;
provided, however, that such date shall not be prior to the date on which the
Board of Directors takes such action.  The Board of Directors shall have the
right, with the consent of a Participant, to convert an Incentive Stock Option
granted under the Plan to a Non-Qualified Option pursuant to Section 6.7.  Plan
Benefits may be granted alone or in addition to other grants under the Plan.

SECTION 6.  Special Provisions Applicable to Options and SARs.
- ---------   -------------------------------------------------

     6.1  Purchase Price and Shares Subject to Options and SARs.
          -----------------------------------------------------

          (a)  The purchase price per share of stock deliverable upon the
     exercise of an Option shall be determined by the Board of Directors,
     provided, however, that (i) in the case of an Incentive Stock Option, the
     --------  -------
     exercise price shall not be less than 100% of the fair market value of such
     stock on the day the option is granted (except as modified in
<PAGE>

                                      -4-

     Section 6.6(b) hereof). The Board of Directors may delegate to the Chief
     Executive Officer of the Company the power to determine the exercise price
     of an option in accordance with written guidelines approved by the Board of
     Directors.

          (b)  Options granted under the Plan may provide for the payment of the
     exercise price by delivery of (i) cash or a check payable to the order of
     the Company in an amount equal to the exercise price of such Options, (ii)
     shares of Common Stock of the Company owned by the Participant having a
     fair market value equal in amount to the exercise price of the Options
     being exercised, or (iii) any combination of (i) and (ii).  The fair market
     value of any shares of the Company's Common Stock which may be delivered
     upon exercise of an Option shall be determined by the Board of Directors.
     The Board of Directors may also permit Participants, either on a selective
     or aggregate basis, to simultaneously exercise Options and sell the shares
     of Common Stock thereby acquired, either to the Company or pursuant to a
     brokerage or similar arrangement, approved in advance by the Board of
     Directors, and to use the proceeds from such sale as payment of the
     purchase price of such shares.

          (c)  If, at the time an Option is granted under the Plan, the
     Company's Common Stock is publicly traded, "fair market value" shall be
     determined as of the last business day for which the prices or quotes
     discussed in this sentence are available prior to the date such Option is
     granted (the "Determination Date") and shall mean (i) the average (on the
     Determination Date) of the high and low prices of the Common Stock on the
     principal national securities exchange on which the Common Stock is traded,
     if such Common Stock is then traded on a national securities exchange; (ii)
     the last reported sale price (on the Determination Date) of the Common
     Stock on the Nasdaq Stock Market if the Common Stock is not then traded on
     a national securities exchange; or (iii) the closing bid price (or average
     of bid prices) last quoted (on the Determination Date) by an established
     quotation service for over-the-counter securities, if the Common Stock is
     not reported on the Nasdaq Stock Market. However, if the Common Stock is
     not publicly traded at the time an Option is granted under the Plan, "fair
     market value" shall be deemed to be the fair value of the Common Stock as
     determined by the Board of Directors after taking into consideration all
     factors which it deems appropriate, including, without limitation, recent
     sale and offer prices of the Common Stock in private transactions
     negotiated at arm's length.

          (d)  If the Company is subject to Section 162(m) of the Code, the
     maximum number of shares with respect to which Options or SARs may be
     granted to any employee, including any cancellations or repricings which
     may occur, shall be limited to 1,500,000 shares in any calendar year.

     6.2  Duration of Options and SARs.  Subject to Section 6.6(b) hereof, each
          ----------------------------
Option and SAR and all rights thereunder shall be expressed to expire on such
date as the Board of Directors may determine, but in no event later than ten
years from the day on which the Option or SAR is granted and shall be subject to
earlier termination as provided herein.
<PAGE>

                                      -5-

     6.3  Exercise of Options and SARs.
          ----------------------------

          (a)  Subject to Section 6.6(b) hereof, each Option and SAR granted
     under the Plan shall be exercisable at such time or times and during such
     period as shall be set forth in the instrument evidencing such Option or
     SAR.  To the extent that an Option or SAR is not exercised by a Participant
     when it becomes initially exercisable, it shall not expire but shall be
     carried forward and shall be exercisable, on a cumulative basis, until the
     expiration of the exercise period.  No partial exercise may be for less
     than ten (10) full shares of Common Stock (or its equivalent).

          (b)  The Board of Directors shall have the right to accelerate the
     date of exercise of any installments of any Option or SAR; provided that
     the Board of Directors shall not accelerate the exercise date of any
     installment of any Option granted to a Participant as an Incentive Stock
     Option (and not previously converted into a Non-Qualified Option pursuant
     to Section 6.7) if such acceleration would violate the annual vesting
     limitation contained in Section 422(d)(1) of the Code, which provides
     generally that the aggregate fair market value (determined at the time the
     Option is granted) of the stock with respect to which Incentive Stock
     Options granted to any Participant are exercisable for the first time by
     such Participant during any calendar year (under all plans of the Company
     and any Related Corporations) shall not exceed $100,000. To the extent the
     aggregate fair market value of the stock with respect to which Incentive
     Stock Options granted to any Participant are exercisable for the first time
     by such Participant during any calendar year (under all plans of the
     Company and any Related Corporations) exceeds $100,000, such Options shall
     be treated as Non-Qualified Options.

     6.4  Nontransferability of Options and SARs.
          --------------------------------------

     No Option or SAR granted under the Plan shall be assignable or transferable
by the Participant, either voluntarily or by operation of law, except by will or
the laws of descent and distribution or, with respect to Non-Qualified Options
and SARs, pursuant to a qualified domestic relations order as defined by the
Code or Title I of the Employee Retirement Income Security Act ("ERISA") or the
rules promulgated thereunder or unless the Participant's non-qualified stock
option agreement granting such options (the "Non-Qualified Stock Option
Agreement") or the Participant's SAR agreement granting such SARs (the "SAR
Agreement") provides otherwise.  Unless otherwise provided by the Non-Qualified
Stock Option Agreement or the SAR Agreement, during the life of the Participant,
the Option or SAR shall be exercisable only by him or her.  If any Participant
should attempt to dispose of or encumber his or her Options or SARs, other than
in accordance with the applicable terms of a Non-Qualified Stock Option
Agreement or SAR Agreement, his or her interest in such Options or SARs shall
terminate.

     6.5  Effect of Termination of Employment or Death.
          --------------------------------------------

          (a)  Except as provided in any applicable option agreement, if a
     Participant ceases to be employed by the Company or a Related Corporation
     for any reason, including retirement but other than death, any Option or
     SAR granted to such Participant
<PAGE>

                                      -6-

     under the Plan shall immediately terminate; provided, however, that any
                                                 --------  -------
     portion of such Option or SAR which was otherwise exercisable on the date
     of termination of the Participant's employment may be exercised within the
     three-month period following the date on which the Participant ceased to be
     so employed, but in no event after the expiration of the exercise period.
     Any such exercise may be made only to the extent of the number of shares
     subject to the Option or SAR which were purchasable on the date of such
     termination of employment. If the Participant dies during such three-month
     period, the Option or SAR shall be exercisable by the Participant's
     personal representatives, heirs or legatees to the same extent and during
     the same period that the Participant could have exercised the Option or SAR
     on the date of his or her death.

          (b)  If the Participant dies while an employee of the Company or any
     Related Corporation, any Option or SAR granted to such Participant under
     the Plan shall be exercisable by the Participant's personal
     representatives, heirs or legatees, for the purchase of that number of
     shares and to the same extent that the Participant could have exercised the
     Option or SAR on the date of his or her death.  The Option or SAR or any
     unexercised portion thereof shall terminate unless so exercised prior to
     the earlier of the expiration of six months from the date of such death or
     the expiration of the exercise period.

     6.6  Designation of Incentive Stock Options; Limitations.
          ---------------------------------------------------

     Options granted under the Plan which are intended to be Incentive Stock
Options qualifying under Section 422 of the Code shall be designated as
Incentive Stock Options and shall be subject to the following additional terms
and conditions:

          (a)  Dollar Limitation. The aggregate fair market value (determined at
               -----------------
     the time the option is granted) of the Common Stock for which Incentive
     Stock Options are exercisable for the first time during any calendar year
     by any person under the Plan (and all other incentive stock option plans of
     the Company and any Related Corporations) shall not exceed $100,000. To the
     extent the aggregate fair market value of the Common Stock for which
     Incentive Stock Options granted to any Participant are exercisable for the
     first time by such Participant during any calendar year (under all plans of
     the Company and any Related Corporations) exceeds $100,000, such Options
     shall be treated as Non-Qualified Options.  In the event that Section
     422(d)(1) of the Code is amended to alter the limitation set forth therein
     so that following such amendment such limitation shall differ from the
     limitation set forth in this Section 6.6(a), the limitation of this Section
     6.6(a) shall be automatically adjusted accordingly.

          (b)  10% Stockholder.  If any employee to whom an Incentive Stock
               ---------------
     Option is to granted pursuant to the provisions of the Plan is on the date
     of grant the owner of stock possessing more than 10% of the total combined
     voting power of all classes of stock of the Company or any Related
     Corporations, then the following special provisions shall be applicable to
     the Incentive Stock Option granted to such individual:
<PAGE>

                                      -7-

               (i)  The option price per share of the Common Stock subject to
          such Incentive Stock Option shall not be less than 110% of the fair
          market value of one share of Common Stock on the date of grant; and

               (ii) The option exercise period shall not exceed five years from
          the date of grant.

     In determining whether the 10% threshold has been reached, the stock
     attribution rules of Section 424(d) of the Code shall apply.

          (c)  Except as modified by the preceding provisions of this Section
     6.6, all of the provisions of the Plan shall be applicable to Incentive
     Stock Options granted hereunder.

     6.7  Conversion of Incentive Stock Options into Non-Qualified Options;
          -----------------------------------------------------------------
Termination of Incentive Stock Options.  The Board of Directors, at the written
- --------------------------------------
request of any Participant, may in its discretion take such actions as may be
necessary to convert such Participant's Incentive Stock Options (or any
installments or portions of installments thereof) that have not been exercised
on the date of conversion into Non-Qualified Options at any time prior to the
expiration of such Incentive Stock Options, regardless of whether the
Participant is an employee of the Company or a Related Corporation at the time
of such conversion.  Such actions may include, but not be limited to, extending
the exercise period or reducing the exercise price of the appropriate
installments of such Options.  At the time of such conversion, the Board of
Directors (with the consent of the Participant) may impose such conditions on
the exercise of the resulting Non-Qualified Options as the Board of Directors in
its discretion may determine, provided that such conditions shall not be
inconsistent with the Plan.  Nothing in the Plan shall be deemed to give any
Participant the right to have such Participant's Incentive Stock Options
converted into Non-Qualified Options, and no such conversion shall occur until
and unless the Board of Directors takes appropriate action.  The Board of
Directors, with the consent of the Participant, may also terminate any portion
of any Incentive Stock Option that has not been exercised at the time of such
termination.

     6.8  Stock Appreciation Rights.  A SAR is the right to receive, without
          -------------------------
payment, an amount equal to the excess, if any, of the fair market value of a
share of Common Stock on the date of exercise over the grant price, which amount
will be multiplied by the number of shares with respect to which the SARs shall
have been exercised.  The grant of SARs under the Plan shall be subject to the
following terms and conditions and shall contain such additional terms and
conditions, not inconsistent with the express terms of the Plan, as the Board of
Directors shall deem desirable:

          (a)  Grant.  SARs may be granted in tandem with, in addition to or
               -----
     completely independent of any Plan Benefit.

          (b)  Grant Price.  The grant price of a SAR may be the fair market
               -----------
     value of a share of Common Stock on the date of grant or such other price
     as the Board of Directors may determine.
<PAGE>

                                      -8-

          (c)  Exercise.  A SAR may be exercised by a Participant in accordance
               --------
     with procedures established by the Board of Directors or as otherwise
     provided in any agreement evidencing any SARs.  The Board of Directors may
     provide that an SAR shall be automatically exercised on one or more
     specified dates.

          (d)  Form of Payment.  Payment upon exercise of an SAR may be made in
               ---------------
     cash, in shares of Common Stock or any combination thereof, as the Board of
     Directors shall determine.

          (e)  Fair Market Value.  Fair market value shall be determined in
               -----------------
     accordance with Section 6.1(c) with the "Determination Date" being
     determined by reference to the date of grant or the date of exercise of an
     SAR, as applicable.

     6.9  Rights as a Stockholder.
          -----------------------

     The holder of an Option or SAR shall have no rights as a stockholder with
respect to any shares covered by the Option or SAR until the date of issue of a
stock certificate to him or her for such shares.  Except as otherwise expressly
provided in the Plan, no adjustment shall be made for dividends or other rights
for which the record date is prior to the date such stock certificate is issued.

     6.10 Special Provisions Applicable to Non-Qualified Options and SARs
          ---------------------------------------------------------------
          Granted to Covered Employees.
          ----------------------------

     If the Company is subject to Section 162(m) of the Code, in order for the
full value of Non-Qualified Options or SARs granted to Covered Employees to be
deductible by the Company for federal income tax purposes, the Company may
intend for such Non-Qualified Options or SARs to be treated as  "qualified
performance-based compensation" as described in Treas. Reg. (S)1.162-27(e) (or
any successor regulation). In such case, Non-Qualified Options or SARs granted
to Covered Employees shall be subject to the following additional requirements:

          (a)  such options and rights shall be granted only by the Committee;
     and

          (b)  the exercise price of such Options and the grant price of such
     SARs granted shall in no event be less than the fair market value of the
     Common Stock as of the date of grant of such Options or SARs.

SECTION 7.  Special Provisions Applicable to Awards
- ---------   ---------------------------------------

     7.1  Grants of Awards.  The Board of Directors may grant a Participant an

appropriate, including, without limitation, restrictions on the pledging, sale,
assignment, transfer or other disposition of such shares and the requirement

     Board of Directors, in a form specified by the Board of Directors agreeing
     to such terms and conditions of the Award as the Board of Directors deems
     appropriate.

          (b)  Shares issued and transferred to a Participant pursuant to an
     Award may, if required by the Board of Directors, be deposited with the
     Treasurer or other officer of the Company designated by the Board of
     Directors to be held until the lapse of the restrictions upon such shares,
     and each Participant shall execute and deliver to the Company stock powers
     enabling the Company to exercise its rights hereunder.

          (c)  Certificates for shares issued pursuant to an Award shall, if the

     shall be registered in the name of the Participant and shall be owned by
     such Participant.  Such Participant shall be the holder of record of such
     shares for all purposes, including voting and receipt of dividends paid

disposed of (except, subject to the provisions of such Participant's Stock
Restriction Agreement, by will or the laws of descent and distribution or
pursuant to a qualified domestic relations order as defined by the Code or Title
I of ERISA or the rules promulgated thereunder), or pledged or hypothecated as
collateral for a loan or as security for the performance of any obligation, or
be otherwise encumbered, and are not subject to attachment, garnishment,
execution or other legal or equitable process, prior to the lapse of
restrictions on such shares, and any attempt at action in contravention of this
Section shall be null and void.  If any Participant should attempt to dispose of
or encumber his or her shares issued pursuant to an Award prior to the lapse of
the restrictions imposed on such shares, his or her interest in such shares
shall terminate.

     7.4  Effect of Termination of Employment or Death on Awards.  If, prior to
          ------------------------------------------------------
the lapse of restrictions applicable to Awards, the Participant ceases to be an
employee of the Company or the Related Corporations for any reason, Awards to
such Participant, as to which restrictions have not lapsed, shall be forfeited
to the Company, effective on the date of the Participant's termination of
employment.  The Board of Directors shall have the sole power, consistent with
applicable laws, to decide in each case to what extent leaves of absence shall
be deemed a termination of employment.

     be as approved by the Board of Directors.

          (b)  Restricted Shares issued and transferred to a Participant may, if
     required by the Board of Directors, be deposited with the Treasurer or
     other officer of the Company designated by the Board of Directors to be

representation may be waived at any time by the Board of Directors.

To the extent any provision of the Plan does not comply with the requirements of
Rule 16b-3, it shall be deemed inoperative to the extent permitted by law and
deemed advisable by the Board of Directors and shall not affect the validity of

Directors may exercise discretion to modify this Plan in any respect necessary
to satisfy the requirements of the revised exemption or its replacement.

SECTION 10.  Recapitalization.

     In the event that dividends are payable in Common Stock of the Company or
in the event there are splits, sub-divisions or combinations of shares of Common
Stock of the Company, the number of shares available under the Plan shall be
increased or decreased proportionately, as the case may be, and the number of
shares deliverable upon the exercise thereafter of any Option previously granted
shall be increased or decreased proportionately, as the case may be, without
change in the aggregate purchase price, and the number of shares to which
granted SARs relate shall be increased or decreased proportionately, as the case
may be, and the grant price of such SARs shall be decreased or increased

reorganization or liquidation of the Company, the Board of Directors of the
Company, or the board of directors of any corporation assuming the obligations
of the Company hereunder, shall, as to outstanding Plan Benefits, either (i)
make appropriate provision for the protection of any such outstanding Plan
Benefits by the substitution on an equitable basis of appropriate stock of the
Company or of the merged, consolidated or otherwise reorganized corporation
which will be issuable in respect of the shares of Common Stock of the Company,
provided only that the excess of the aggregate fair market value of the shares
subject to the Plan Benefits immediately after such substitution over the
purchase price thereof is not more than the excess of the aggregate fair market
value of the shares subject to such Plan Benefits immediately before such
substitution over the purchase price thereof, (ii) upon written notice to the
Participants, provide that all unexercised Plan Benefits must be
<PAGE>

                                      -12-

exercised within a specified number of days of the date of such notice or such
Plan Benefits will be terminated, or (iii) upon written notice to the
Participants, provide that the Company or the merged, consolidated or otherwise
reorganized corporation shall have the right, upon the effective date of any
such merger, consolidation, sale of assets or reorganization, to purchase all
Plan Benefits held by each Participant and unexercised as of that date at an
amount equal to the aggregate fair market value on such date of the shares
subject to the Plan Benefits held by such Participant over the aggregate
purchase price therefor, such amount to be paid in cash or, if stock of the
merged, consolidated or otherwise reorganized corporation is issuable in respect
of the shares of the Common Stock of the Company, then, in the discretion of the
Board of Directors, in stock of such merged, consolidated or otherwise
reorganized corporation equal in fair market value to the aforesaid amount. In
any such case the Board of Directors shall, in good faith, determine fair market
value and may, in its discretion, advance the lapse of any waiting or
installment periods and exercise dates.

     (b)  Notwithstanding anything herein to the contrary, in the event that
following or in connection with a Change-in-Control (as defined below), a

Company is (i) terminated by the Company for any reason other than Cause (as

"Incumbent Directors") cease for any reason to constitute at least a majority of
the Board of Directors, provided that any individual becoming a director
subsequent to the date hereof whose election or nomination for election was
approved by a vote of at least a majority of the then Incumbent Directors shall
be, for the purposes of this provision, considered as though such individual
were an Incumbent Director; (iii) any consolidation or merger of the Company
with any other entity (including, without limitation, a triangular merger) where
the stockholders of the Company immediately prior to the consolidation or
merger, would not, immediately after the consolidation or merger, beneficially
own, directly or indirectly, shares representing fifty percent (50%) of the
combined voting power of all of the outstanding securities of the entity issuing
cash or securities in the consolidation or merger (or its ultimate parent
corporation, if any); (iv) a person, including a "person" as defined in Section
13(d)(3) of the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), other than the Company or an employee benefit plan sponsored by the
Company, becomes the beneficial owner (as defined in Rule 13d-3 under the
Exchange Act), directly or indirectly, of securities of the Company representing
forty percent (40%) or more of the total voting power represented by the
Company's then outstanding voting securities, except for a person who was a

beneficial owner of forty percent (40%) or more of the total voting power of the
Company's outstanding voting securities on April 29, 1999; or (v) the Board of
Directors of the Company, by a vote of a majority of all the Directors, adopts a
resolution to the effect that a "Change-in-Control" has occurred for purposes of
this Agreement.  The term "Good Reason" shall mean that (i) the Participant's
compensation has been materially reduced, (ii) the Participant's position,
duties or responsibilities have been materially changed, (iii) the Participant,
if an employee of the Company, has been required to move his or her principal
residence because his primary place of employment is moved to a location greater
than thirty (30) miles away from its then current location, (iv) the Company has
not paid to the Participant when due any salary, bonus or other material benefit
due to him or her, or (v) there exists a breach by the Company of any material
term or provision of any employment agreement between it and the Participant,
provided, however, that, in any such event, the Participant shall notify the
Company of such event and give it fifteen (15) days to remedy the situation
before terminating his or her employment.

SECTION 12.  No Special Employment Rights.
- ----------   ----------------------------

     Nothing contained in the Plan or in any Plan Benefit documentation shall
confer upon any Participant receiving a grant of any Plan Benefit any right with
respect to the continuation of his or her employment by the Company (or any
Related Corporation) or interfere in any way with the right of the Company (or
any Related Corporation), subject to the terms of any separate employment
agreement to the contrary, at any time to terminate such employment or to
increase or decrease the compensation of the Participant from the rate in
existence at the time of the grant of any Plan Benefit.  Whether an authorized
leave of absence, or absence in military or government service, shall constitute
termination of employment shall be determined by the Board of Directors.

SECTION 13.  Amendment of the Plan.
- ----------   ---------------------

     The Board of Directors may at any time and from time to time modify or
amend the Plan in any respect.  The termination or any modification or amendment

affect his or her rights under any Plan Benefit previously granted.  With the
consent of the affected Participant, the Board of Directors may amend
outstanding agreements relating to any Plan Benefit, in a manner not
inconsistent with the Plan.  The Board of Directors hereby reserves the right to
amend or modify the terms and provisions of the Plan and of any outstanding
Options to the extent necessary to qualify any or all Options under the Plan for
such favorable federal income tax treatment (including deferral of taxation upon
exercise) as may be afforded incentive stock options under Section 422 of the
Code, provided, however, that the consent of an optionee is required if such
amendment or modification would cause unfavorable income tax treatment for such
optionee.

all shares available for issuance under the Plan shall have been issued pursuant
to any Awards or Purchases or the exercise or cancellation of Options and SARs

then Plan Benefits outstanding on such date shall continue to have force and
effect in accordance with the provisions of the instruments evidencing such Plan
Benefits.

                                 DSL.net, Inc.

                       1999 EMPLOYEE STOCK PURCHASE PLAN



Article 1 - Purpose.
- -------------------

   This 1999 Employee Stock Purchase Plan (the "Plan") is intended to encourage
stock ownership by all eligible employees of DSL.net, Inc., a Delaware
corporation (the "Company"), and its participating subsidiaries (as defined in
Article 17) so that they may share in the growth of the Company by acquiring or
increasing their proprietary interest in the Company.  The Plan is designed to
encourage eligible employees to remain in the employ of the Company and its
participating subsidiaries.  The Plan is intended to constitute an "employee
stock purchase plan" within the meaning of Section 423(b) of the Internal
Revenue Code of 1986, as amended (the "Code").

Article 2 - Administration of the Plan.
- --------------------------------------

   The Plan may be administered by a committee appointed by the Board of
Directors of the Company (the "Committee"), subject to such limitations as may
be approved by the Board of Directors.  The Committee shall consist of not less
than two members of the Company's Board of Directors.  The Board of Directors
may from time to time remove members from, or add members to, the Committee.
Vacancies on the Committee, however caused, shall be filled by the Board of
Directors.  The Committee may select one of its members as Chairman, and shall
hold meetings at such times and places as it may determine.  Acts by a majority
of the Committee, or acts reduced to or approved in writing by a majority of the
members of the Committee, shall be the valid acts of the Committee, subject to
such limitations as approved by the Board of Directors.

   The interpretation and construction by the Committee of any provisions of the
Plan or of any option granted under it shall be conclusive subject to such
limitations as are approved by the Board of Directors.  The Committee may from
time to time adopt such rules and regulations for carrying out the Plan as it
may deem best, provided that any such rules and regulations shall be subject to
such limitations as approved by the Board of Directors and applied on a uniform
basis to all employees under the Plan.  No member of the Board of Directors or
the Committee shall be liable for any action or determination made in good faith
with respect to the Plan or any option granted under it.

   In the event the Board of Directors fails to appoint or disbands the
Committee, the Board of Directors shall have all power and authority to
administer the Plan.  In such event, the word "Committee" wherever used herein
shall be deemed to mean the Board of Directors.

Article 3 - Eligible Employees.
- ------------------------------

   All employees of the Company or any of its participating subsidiaries whose
customary employment is more than 20 hours per week and for more than three
months in any calendar year and who have completed at least three months of
service shall be eligible to receive options under the Plan to purchase common
stock of the Company, and all eligible employees shall have the same rights and
privileges hereunder; provided, however, that with respect to the first Payment
Period (as defined in Article 5), all persons who are employees of the Company
or any of its participating subsidiaries on the
<PAGE>

                                      -2-

date of the closing of the initial public offering whose customary employment is
more than 20 hours per week and for more than three months in any calendar year
shall be eligible to receive options under the Plan to purchase common stock of
the Company. Persons who are eligible employees on the first business day of any
Payment Period shall receive their options as of such day. Persons who become
eligible employees after any date on which options are granted under the Plan
shall be granted options on the first day of the next succeeding Payment Period
on which options are granted to eligible employees under the Plan. In no event,
however, may an employee be granted an option if such employee, immediately
after the option was granted, would be treated as owning stock possessing five
percent or more of the total combined voting power or value of all classes of
stock of the Company or of any parent corporation or subsidiary corporation, as
the terms "parent corporation" and "subsidiary corporation" are defined in
Section 424(e) and (f) of the Code. For purposes of determining stock ownership
under this paragraph, the rules of Section 424(d) of the Code shall apply, and
stock which the employee may purchase under outstanding options shall be treated
as stock owned by the employee.

Article 4 - Stock Subject to the Plan.
- -------------------------------------

   The stock subject to the options under the Plan shall be shares of the
Company's authorized but unissued common stock, par value $.0005 per share (the
"Common Stock"), or shares of Common Stock reacquired by the Company, including
shares purchased in the open market.  The aggregate number of shares which may
be issued pursuant to the Plan is 300,000, subject to adjustment as provided in
Article 12.  If any option granted under the Plan shall expire or terminate for
any reason without having been exercised in full or shall cease for any reason
to be exercisable in whole or in part, the unpurchased shares subject thereto
shall again be available under the Plan.

Article 5 - Payment Period and Stock Options.
- --------------------------------------------

   The first Payment Period during which payroll deductions will be accumulated
under the Plan shall commence immediately upon the initial offering of the
Common Stock to the public (the "Offering") and shall end on February 29, 2000.
For the remainder of the duration of the Plan, Payment Periods shall consist of
the six-month periods commencing on March 1 and September 1 and ending on August
31 and the last day of February, respectively, of each calendar year.

   Twice each year, on the first business day of each Payment Period, the
Company will grant to each eligible employee who is then a participant in the
Plan an option to purchase on the last day of such Payment Period, at the
exercise price hereinafter provided for, a maximum of 500 shares, on condition
that such employee remains eligible to participate in the Plan throughout the
remainder of such Payment Period. The participant shall be entitled to exercise
the option so granted only to the extent of the participant's accumulated
payroll deductions on the last day of such Payment Period. If the participant's
accumulated payroll deductions on the last day of the Payment Period would
enable the participant to purchase more than 500 shares except for the 500-share
limitation, the excess of the amount of the accumulated payroll deductions over
the aggregate purchase price of the 500 shares shall be promptly refunded to the
participant by the Company, without interest. The exercise price per share for
each Payment Period shall be the lesser of (i) 85% of the average market price
of the Common Stock on the first business day of the Payment Period and (ii) 85%
of the average market price of the Common Stock on the last business day of the
Payment Period, in either event rounded up to the nearest cent. Notwithstanding
the foregoing, with regard to the first Payment Period, the exercise price shall
be calculated as the lesser of (i) 85% of the price per share at which the
Common Stock is sold to the public upon the Offering, without regard to any
applicable discounts or commission provided to the underwriters, and (ii) 85% of
the average market price of the Common Stock on the last business day of
<PAGE>

                                      -3-

the First Payment Period. The foregoing limitation on the number of shares
subject to option and the Exercise price shall be subject to adjustment as
provided in Article 12.

   For purposes of the Plan, the term "average market price" on any date means
(i) the average on that date of the high and low prices of the Common Stock on
the principal national securities exchange on which the Common Stock is traded,
if the Common Stock is then traded on a national securities exchange; or (ii)
the last reported sale price on that date of the Common Stock on the Nasdaq
National Market or the Nasdaq SmallCap Market, if the Common Stock is not then
traded on a national securities exchange; or (iii) the average of the closing
bid and asked prices last quoted on that date by an established quotation
service for over-the-counter securities, if the Common Stock is not reported on
the Nasdaq National Market or the Nasdaq SmallCap Market; or (iv) if the Common
Stock is not publicly traded, the fair market value of the Common Stock as
determined by the Committee after taking into consideration all factors which it
deems appropriate, including, without limitation, recent sale and offer prices
of the Common Stock in private transactions negotiated at arm's length.

   For purposes of the Plan, the term "business day" means a day on which there
is trading on the NASDAQ National Market or the aforementioned national
securities exchange, whichever is applicable pursuant to the preceding
paragraph; and if neither is applicable, a day that is not a Saturday, Sunday or
legal holiday in State of Connecticut.

   No employee shall be granted an option which permits the employee's right to
purchase stock under the Plan, and under all other Section 423(b) employee stock
purchase plans of the Company and any parent or subsidiary corporations, to
accrue at a rate which exceeds $25,000 of fair market value of such stock
(determined on the date or dates that options on such stock were granted) for
each calendar year in which such option is outstanding at any time.  The purpose
of the limitation in the preceding sentence is to comply with Section 423(b)(8)
of the Code.  If the participant's accumulated payroll deductions on the last
day of the Payment Period would otherwise enable the participant to purchase
Common Stock in excess of the Section 423(b)(8) limitation described in this
paragraph, the excess of the amount of the accumulated payroll deductions over
the aggregate purchase price of the shares actually purchased shall be promptly
refunded to the participant by the Company, without interest.

Article 6 - Exercise of Option.
- ------------------------------

   Each eligible employee who continues to be a participant in the Plan on the
last day of a Payment Period shall be deemed to have exercised his or her option
on such date and shall be deemed to have purchased from the Company such number
of full shares of Common Stock reserved for the purpose of the Plan as the
participant's accumulated payroll deductions on such date will pay for at the
Exercise price, subject to the 500-share limit of the option and the Section
423(b)(8) limitation described in Article 5.  If the individual is not a
participant on the last day of a Payment Period, then he or she shall not be
entitled to exercise his or her option.  Only full shares of Common Stock may be
purchased under the Plan.  Unused payroll deductions remaining in a
participant's account at the end of a Payment Period by reason of the inability
to purchase a fractional share shall be carried forward to the next Payment
Period.

Article 7 - Authorization for Entering the Plan.
- -----------------------------------------------

   An employee may elect to enter the Plan by filling out, signing and
delivering to the Company an authorization:
<PAGE>

                                      -4-

       A.  Stating the percentage to be deducted regularly from the employee's
   pay;

       B.  Authorizing the purchase of stock for the employee in each Payment
   Period in accordance with the terms of the Plan; and

       C.  Specifying the exact name or names in which stock purchased for the
   employee is to be issued as provided under Article 11 hereof.

Such authorization must be received by the Company at least ten days before the
first day of the next succeeding Payment Period and shall take effect only if
the employee is an eligible employee on the first business day of such Payment
Period; provided, however, that with respect to the first Payment Period, such
authorization must be received by the Company no later than two (2) weeks
following the date of the closing of the initial public offering of shares of
the Company's Common Stock.

   Unless a participant files a new authorization or withdraws from the Plan,
the deductions and purchases under the authorization the participant has on file
under the Plan will continue from one Payment Period to succeeding Payment
Periods as long as the Plan remains in effect.

   The Company will accumulate and hold for each participant's account the
amounts deducted from his or her pay.  No interest will be paid on these
amounts.

Article 8 - Maximum Amount of Payroll Deductions.
- ------------------------------------------------

   An employee may authorize payroll deductions in an amount (expressed as a
whole percentage) not less than one percent (1%) but not more than ten percent
(10%) of the employee's total compensation, including base pay or salary and any
overtime, bonuses and commissions.

Article 9 - Change in Payroll Deductions.
- ----------------------------------------

   Deductions may not be increased or decreased during a Payment Period.
However, a participant may withdraw in full from the Plan.

Article 10 - Withdrawal from the Plan.
- -------------------------------------

   A participant may withdraw from the Plan (in whole but not in part) at any
time prior to the last day of a Payment Period by delivering a withdrawal notice
to the Company.  Effective upon the receipt of any such withdrawal notice, the
Company shall promptly refund, without interest, the entire balance of such
participant's payroll deduction account under the Plan.

   To re-enter the Plan, an employee who has previously withdrawn must file a
new authorization at least ten days before the first day of the next Payment
Period in which he or she wishes to participate.  The employee's re-entry into
the Plan becomes effective at the beginning of such Payment Period, provided
that he or she is an eligible employee on the first business day of the Payment
Period.

Article 11 - Issuance of Stock.
- ------------------------------

   Certificates for stock issued to participants shall be delivered as soon as
practicable after each Payment Period by the Company's transfer agent.
<PAGE>

                                      -5-

   Stock purchased under the Plan shall be issued only in the name of the
participant, or if the participant's authorization so specifies, in the name of
the participant and another person of legal age as joint tenants with rights of
survivorship.

Article 12 - Adjustments.
- ------------------------

   Upon the happening of any of the following described events, a participant's
rights under outstanding options granted under the Plan shall be adjusted as
hereinafter provided:

       A.  In the event that the shares of Common Stock shall be subdivided or
   combined into a greater or smaller number of shares or if, upon a
   reorganization, split-up, liquidation, recapitalization or the like of the
   Company, the shares of Common Stock shall be exchanged for other securities
   of the Company, each participant shall be entitled, subject to the conditions
   herein stated, to purchase such number of shares of Common Stock or amount of
   other securities of the Company as were exchangeable for the number of shares
   of Common Stock that such participant would have been entitled to purchase
   except for such action, and appropriate adjustments shall be made in the
   purchase price per share to reflect such subdivision, combination or
   exchange; and

       B.  In the event the Company shall issue any of its shares as a stock
   dividend upon or with respect to the shares of stock of the class which shall
   at the time be subject to option hereunder, each participant upon exercising
   such an option shall be entitled to receive (for the purchase price paid upon
   such exercise) the shares as to which the participant is exercising his or
   her option and, in addition thereto (at no additional cost), such number of
   shares of the class or classes in which such stock dividend or dividends were
   declared or paid, and such amount of cash in lieu of fractional shares, as is
   equal to the number of shares thereof and the amount of cash in lieu of
   fractional shares, respectively, which the participant would have received if
   the participant had been the holder of the shares as to which the participant
   is exercising his or her option at all times between the date of the granting
   of such option and the date of its exercise.

   Upon the happening of any of the foregoing events, the class and aggregate
number of shares set forth in Article 4 hereof which are subject to options
which have been or may be granted under the Plan and the limitations set forth
in the second paragraph of Article 5 shall also be appropriately adjusted to
reflect the events specified in paragraphs A and B above.  Notwithstanding the
foregoing, any adjustments made pursuant to paragraphs A or B shall be made only
after the Committee, based on advice of counsel for the Company, determines
whether such adjustments would constitute a "modification" (as that term is
defined in Section 424 of the Code).  If the Committee determines that such
adjustments would constitute a modification, it may refrain from making such
adjustments.

   If the Company is to be consolidated with or acquired by another entity in a
merger, a sale of all or substantially all of the Company's assets or otherwise
(an "Acquisition"), the Committee or the board of directors of any entity
assuming the obligations of the Company hereunder (the "Successor Board") shall,
with respect to options then outstanding under the Plan, either (i) make
appropriate provision for the continuation of such options by arranging for the
substitution on an equitable basis for the shares then subject to such options
either (a) the consideration payable with respect to the outstanding shares of
the Common Stock in connection with the Acquisition, (b) shares of stock of the
successor corporation, or a parent or subsidiary of such corporation, or (c)
such other securities as the Successor Board deems appropriate, the fair market
value of which shall not materially exceed the fair market value of the shares
of Common Stock subject to such options immediately preceding the Acquisition;
or (ii) terminate each participant's options in exchange for a cash payment
equal to the excess of (a) the fair market value on
<PAGE>

                                      -6-

the date of the Acquisition of the number of shares of Common Stock that the
participant's accumulated payroll deductions as of the date of the Acquisition
could purchase at an exercise price determined with reference only to the first
business day of the applicable Payment Period and subject to the 500-share, Code
Section 423(b)(8) and fractional-share limitations on the amount of stock a
participant would be entitled to purchase, over (b) the result of multiplying
such number of shares by such exercise price.

   The Committee or Successor Board shall determine the adjustments to be made
under this Article 12, and its determination shall be conclusive.

Article 13 - No Transfer or Assignment of Employee's Rights.
- -----------------------------------------------------------

   An employee's rights under this Plan are the employee's alone and may not be
transferred or assigned to or availed of by, any other person other than by will
or the laws of descent and distribution.  Any option granted under the Plan may
not be transferred or assigned and may be exercised only by the participant.

Article 14 - Termination of Employee's Rights.
- ---------------------------------------------

   Whenever a participant ceases to be an eligible employee because of
retirement, voluntary or involuntary termination, resignation, layoff,
discharge, death or for any other reason, his or her rights under the Plan shall
immediately terminate, and the Company shall promptly refund, without interest,
the entire balance of his or her payroll deduction account under the Plan.
Notwithstanding the foregoing, eligible employment shall be treated as
continuing intact while a participant is on military leave, sick leave or other
bona fide leave of absence, for up to 90 days, or for so long as the
participant's right to re-employment is guaranteed either by statute or by
contract, if longer than 90 days.

   If a participant's payroll deductions are interrupted by any legal process, a
withdrawal notice will be considered as having been received from the
participant on the day the interruption occurs.

Article 15 - Termination and Amendments to Plan.
- -----------------------------------------------

   Unless terminated sooner as provided below, the Plan shall terminate on
December 31, 2009.  The Plan may be terminated at any time by the Company's
Board of Directors but such termination shall not affect options then
outstanding under the Plan.  It will terminate in any case when all or
substantially all of the unissued shares of stock reserved for the purposes of
the Plan have been purchased.  If at any time shares of stock reserved for the
purpose of the Plan remain available for purchase but not in sufficient number
to satisfy all then unfilled purchase requirements, the available shares shall
be apportioned among participants in proportion to the amount of payroll
deductions accumulated on behalf of each participant that would otherwise be
used to purchase stock, and the Plan shall terminate.  Upon such termination or
any other termination of the Plan, all payroll deductions not used to purchase
stock will be refunded, without interest.

   The Committee or the Board of Directors may from time to time adopt
amendments to the Plan provided that, without the approval of the stockholders
of the Company, no amendment may (i) increase the number of shares that may be
issued under the Plan; (ii) change the class of employees eligible to receive
options under the Plan, if such action would be treated as the adoption of a new
plan for purposes of Section 423(b) of the Code; or (iii) cause Rule 16b-3 under
the Securities Exchange Act of 1934 to become inapplicable to the Plan.
<PAGE>

                                      -7-

Article 16 - Limits on Sale of Stock Purchased under the Plan.
- -------------------------------------------------------------

   The Plan is intended to provide shares of Common Stock for investment and not
for resale.  The Company does not, however, intend to restrict or influence any
employee in the conduct of his or her own affairs.  An employee may, therefore,
sell stock purchased under the Plan at any time the employee chooses, subject to
compliance with any applicable federal or state securities laws and subject to
any restrictions imposed under Article 21 to ensure that tax withholding
obligations are satisfied.  THE EMPLOYEE ASSUMES THE RISK OF ANY MARKET
FLUCTUATIONS IN THE PRICE OF THE STOCK.

Article 17 - Participating Subsidiaries.
- ---------------------------------------

   The term "participating subsidiary" shall mean any present or future
subsidiary of the Company, as that term is defined in Section 424(f) of the
Code, which is designated from time to time by the Board of Directors to
participate in the Plan.  The Board of Directors shall have the power to make
such designation before or after the Plan is approved by the stockholders.

Article 18 - Optionees Not Stockholders.
- ---------------------------------------

   Neither the granting of an option to an employee nor the deductions from his
or her pay shall constitute such employee a stockholder of the shares covered by
an option until such shares have been actually purchased by the employee.

Article 19 - Application of Funds.
- ---------------------------------

   The proceeds received by the Company from the sale of Common Stock pursuant
to options granted under the Plan will be used for general corporate purposes.

Article 20 - Notice to Company of Disqualifying Disposition.
- -----------------------------------------------------------

   By electing to participate in the Plan, each participant agrees to notify the
Company in writing immediately after the participant transfers Common Stock
acquired under the Plan, if such transfer occurs within two years after the
first business day of the Payment Period in which such Common Stock was
acquired.  Each participant further agrees to provide any information about such
a transfer as may be requested by the Company or any subsidiary corporation in
order to assist it in complying with the tax laws.  Such dispositions generally
are treated as "disqualifying dispositions" under Sections 421 and 424 of the
Code, which have certain tax consequences to participants and to the Company and
its participating subsidiaries.

Article 21 - Withholding of Additional Income Taxes.
- ---------------------------------------------------

   By electing to participate in the Plan, each participant acknowledges that
the Company and its participating subsidiaries are required to withhold taxes
with respect to the amounts deducted from the participant's compensation and
accumulated for the benefit of the participant under the Plan, and each
participant agrees that the Company and its participating subsidiaries may
deduct additional amounts from the participant's compensation, when amounts are
added to the participant's account, used to purchase Common Stock or refunded,
in order to satisfy such withholding obligations.  Each participant further
acknowledges that when Common Stock is purchased under the Plan the Company and
its participating subsidiaries may be required to withhold taxes with respect to
all or a portion of the
<PAGE>

                                      -8-

difference between the fair market value of the Common Stock purchased and its
purchase price, and each participant agrees that such taxes may be withheld from
compensation otherwise payable to such participant. It is intended that tax
withholding will be accomplished in such a manner that the full amount of
payroll deductions elected by the participant under Article 7 will be used to
purchase Common Stock. However, if amounts sufficient to satisfy applicable tax
withholding obligations have not been withheld from compensation otherwise
payable to any participant, then, notwithstanding any other provision of the
Plan, the Company may withhold such taxes from the participant's accumulated
payroll deductions and apply the net amount to the purchase of Common Stock,
unless the participant pays to the Company, prior to the exercise date, an
amount sufficient to satisfy such withholding obligations. Each participant
further acknowledges that the Company and its participating subsidiaries may be
required to withhold taxes in connection with the disposition of stock acquired
under the Plan and agrees that the Company or any participating subsidiary may
take whatever action it considers appropriate to satisfy such withholding
requirements, including deducting from compensation otherwise payable to such
participant an amount sufficient to satisfy such withholding requirements or
conditioning any disposition of Common Stock by the participant upon the payment
to the Company or such subsidiary of an amount sufficient to satisfy such
withholding requirements.

Article 22 - Governmental Regulations.
- -------------------------------------

   The Company's obligation to sell and deliver shares of Common Stock under the
Plan is subject to the approval of any governmental authority required in
connection with the authorization, issuance or sale of such shares.

   Government regulations may impose reporting or other obligations on the
Company with respect to the Plan.  For example, the Company may be required to
identify shares of Common Stock issued under the Plan on its stock ownership
records and send tax information statements to employees and former employees
who transfer title to such shares.

Article 23 - Governing Law.
- --------------------------

   The validity and construction of the Plan shall be governed by the laws of
State of Delaware, without giving effect to the principles of conflicts of law
thereof.
