            SERIES A PREFERRED STOCK AND WARRANT PURCHASE AGREEMENT

     THIS SERIES A PREFERRED STOCK AND WARRANT PURCHASE AGREEMENT is made as of
the 8th day of January, 1999, by and among dsl.net, inc., a Delaware corporation
(the "Company"), and the investors listed on Schedule A hereto, each of which is
herein referred to as an "Investor" and together as the "Investors."

     THE PARTIES HEREBY AGREE AS FOLLOWS:

     1.   Purchase and Sale of Stock and Warrants.
          ---------------------------------------

     1.1  Sale and Issuance of Series A Preferred Stock and Warrants.
          ----------------------------------------------------------

          (a)  The Company shall adopt and file with the Secretary of State of
Delaware on or before the Closing (as defined below) the Restated Certificate of
Incorporation in the form attached hereto as Exhibit A (the "Restated
                                             ---------
Certificate").

          (b)  On or prior to the Closing (as defined below), the Company shall
have authorized (i) the sale and issuance to the Investors of 3,500,000 shares
of Series A Preferred Stock (as defined below), (ii) the issuance of the shares
of Common Stock (as defined below) to be issued upon conversion of the Series A
Preferred Stock (the "Common Shares"), (iii) the sale and issuance to the
Investors of warrants in substantially the form attached hereto as Exhibit B
                                                                   ---------
(each individually a "Warrant" and collectively the "Warrants") exercisable for
up the number shares of Series B Preferred Stock (as defined below) set forth
opposite each respective Investor's name on Schedule A hereto and (iv) the
issuance of the Series B Preferred Stock upon exercise of the Warrants (the
"Warrant Shares") and the issuance of the Common Stock issuable upon conversion
of the Warrant Shares.  The Common Shares and shares of Common Stock issuable
upon conversion of the Warrant Shares are collectively referred to herein as the
"Conversion Shares."  The Series A Preferred Stock and the Conversion Shares
shall have the rights, preferences, privileges and restrictions set forth
herein, in the Investors' Rights Agreement of even date herewith, and in the
Restated Certificate.

          (c)  Subject to the terms and conditions of this Agreement, each
Investor agrees, severally and not jointly, to purchase at the Closing and the
Company agrees to sell and issue to each Investor at the Closing that number of
shares of the Company's Series A Preferred Stock set forth opposite such
Investor's name on Schedule A hereto for the purchase price set forth thereon.
                   ----------
In addition, the Company agrees to issue the Warrants to the Investors, in
consideration of the Investors' participation in the transaction contemplated by
this Agreement.  The Warrants received by each Investor shall be exercisable for
the number of shares of the Company's Series B Preferred Stock set forth
opposite such Investor's name on Schedule A hereto at the initial per share
exercise price specified in Section 2 of the Warrant (subject to adjustment as
set forth in the Warrants), in accordance with the terms of the Warrants.
<PAGE>

                                      -2-

     1.2  Closing.  The purchase and sale of the Series A Preferred Stock and
          -------
Warrants shall take place at the offices of Day, Berry and Howard LLP, CityPlace
I, Hartford, Connecticut, at 9:30 A.M., on January 8, 1999, or at such other
time and place as the Company and Investors acquiring in the aggregate more than
fifty percent (50%) the shares of Series A Preferred Stock sold pursuant hereto
mutually agree upon orally or in writing (which time and place are designated as
the "Closing").  At the Closing the Company shall deliver to each Investor a
certificate representing the Series A Preferred Stock purchased thereby against
payment of the purchase price therefor by wire transfer, cancellation of
indebtedness, or any combination thereof.  The Company shall also deliver the
Warrants to the Investors.  In the event that payment by an Investor is made, in
whole or in part, by cancellation of indebtedness, then such Investor shall
surrender to the Company for cancellation at the Closing any evidence of such
indebtedness or shall execute an instrument of cancellation in form and
substance acceptable to the Company.

     2.   Company Right to Repurchase Warrant Shares.
          ------------------------------------------

     2.1  Scope of Repurchase Right.  Each time an Investor or any transferee of
          -------------------------
all or a part of its Warrant ("Holder") chooses to exercise such Warrant
pursuant to Section 4 or Section 5 of the Warrant (a "Warrant Exercise") all
Warrant Shares purchased thereby, and all shares of Common Stock issued or
issuable upon conversion of such Warrant Shares, initially shall be Restricted
Shares (as defined in Section 2.5 below) and shall be subject to a right (but
not an obligation) of repurchase by the Company (the "Repurchase Right") until
five business days after the closing of a Public Offering (as defined in Section
2.3 below) or Acquisition Transaction (as defined in Section 2.3 below) as
provided below.

     2.2  Repurchase Cost.  If the Company exercises the Repurchase Right with
          ---------------
respect to outstanding Warrant Shares, it shall pay the Holder thereof an amount
in cash or cash equivalents equal to the Exercise Price (as defined in the
Warrant) paid with respect to each of the Restricted Shares being repurchased
(as adjusted for stock splits, stock dividends, reverse stock splits,
recapitalizations and the like after the date of exercise), plus interest on the
Exercise Price from the date the applicable Warrant was exercised for such
Shares to the date of repurchase at the rate of eight percent (8%) per annum,
less any dividends which have been paid (or for which the record date has
passed) on such Restricted Shares since the date they were issued.

     2.3  Exercise of Repurchase Right.  The Repurchase Right shall be
          ----------------------------
exercisable, in whole or in part, as follows:

          (a)  The Repurchase Right shall be exercisable by the Company (or its
successor) as to all Warrant Shares commencing immediately prior to, but subject
in all events to the completion of, the occurrence of one of the following
events, if such event occurs on or prior to January 8, 2000:

               (i) the closing of a firm commitment underwritten public offering
     pursuant to an effective registration statement under the Securities Act of
     1933, as amended (a "Public Offering"), at a price to the public of not
     less than $5.00 for each share of Series B Preferred Stock, or the Common
     Stock issuable upon conversion of one share of Series B Preferred Stock (as
     adjusted for stock splits, reverse stock splits and the like effected after
     the date of this Agreement); or
<PAGE>

                                      -3-

               (ii) the closing of the Company's sale of all or substantially
     all of its assets or the acquisition of the Company by another entity by
     means of merger, consolidation or other transaction or series of related
     transactions resulting in the exchange of the outstanding shares of the
     Company's capital stock such that the stockholders of the Company prior to
     such transaction own, directly or indirectly, less than 50% of the voting
     power of the surviving entity (an "Acquisition Transaction"), if the Fair
     Market Value (as defined below) of the consideration to be received for one
     share of Series B Preferred Stock upon such event is greater than or equal
     to five (5) times the Exercise Price.

          (b)  Commencing immediately prior to, and subject in all events to the
completion of, the closing of a Public Offering or the closing of an Acquisition
Transaction after January 8, 2000, the Repurchase Right shall be exercisable for
the number of Warrant Shares determined as follows:

               (i)  if the fair market value of one share of Series B Preferred
     Stock upon such Public Offering or Acquisition Transaction (as determined
     in good faith by the Board of Directors of the Company, or in the event of
     a Public Offering, by the initial "Price to Public" of one share of such
     Series B Preferred Stock, or Common Stock issuable upon conversion of such
     Series B Preferred Stock, specified in the final prospectus with respect to
     such offering) (the "Fair Market Value") is more than ten (10) times
     greater than the Exercise Price (as defined in the Warrants), the
     Repurchase Right may be exercised to repurchase that number of Warrant
     Shares issued pursuant to each Warrant computed by the following formula,
     with all Warrant Shares issued pursuant to such Warrant in excess of such
     amount no longer subject to the Repurchase Right:

          A = (BxD)((C/D) - 10)

          Where:    A = the number of Warrant Shares subject to exercise of the
                    Repurchase Right

          B = ten percent (10%) of the Originally Purchasable Number of Shares
                    (as defined in the Warrant), as adjusted pursuant to Section
                    8 of the Warrant

                    C = the Fair Market Value

          D = the Exercise Price (as defined in the Warrant)

               (ii) if A is equal to or greater than the number of Warrant
     Shares issued pursuant to a Warrant, then all Warrant Shares issued
     pursuant to such Warrant shall be subject to the Repurchase Right, and the
     amount by which A exceeds such number of shares shall be known as the
     "Excess Repurchasable Shares" with respect to such Warrant (or, if such
     Warrant is later transferred in part, with respect to all parts of such
     Warrant).
<PAGE>

                                      -4-

               (iii)  if the Fair Market Value is less than or equal to ten (10)
     times greater than the Exercise Price, no Warrant Shares shall be subject
     to the Repurchase Right.

          (c)  The Repurchase Right shall be exercisable only by written notice
delivered to the Holder at least three (3) business days prior to the closing of
a Public Offering or Acquisition Transaction.  The notice shall set forth the
date on which the repurchase is to be effected and shall specify that the
repurchase shall be conditioned upon the closing of such transaction.  Such date
shall not be more than five (5) business days after the date of such closing.
If such transaction does not occur for any reason, all Warrant Shares which were
Restricted Shares shall continue to be Restricted Shares.  The certificate(s)
representing the Restricted Shares to be repurchased shall, prior to the close
of business on the date specified for the repurchase, be delivered to the
Company properly endorsed for transfer.  The Company shall, concurrently with
the receipt of such certificate(s), pay to the Investors or their transferees
the purchase price determined according to Subsection 2.2 above.  Payment shall
be made in cash or cash equivalents.

          (d)  The Repurchase Right shall expire, and all Restricted Shares
shall cease to be subject to the Repurchase Right, on the sixth business day
following the closing of a Public Offering or Acquisition Transaction.

     2.4  Termination of Rights as Stockholder.  If the Company makes available,
          ------------------------------------
at the time and place and in the amount and form provided in this Agreement, the
consideration for the Restricted Shares to be repurchased in accordance with
this Section 2, then after such time the person from whom such Restricted Shares
are to be repurchased shall no longer have any rights as a holder of such
Restricted Shares (other than the right to receive payment of such consideration
in accordance with this Agreement). Such Restricted Shares shall be deemed to
have been repurchased in accordance with the applicable provisions hereof,
whether or not the certificate(s) therefor have been delivered as required by
this Agreement.

     2.5  Definition.  "Restricted Share" shall mean a Warrant Share that is
          ----------
subject to a Repurchase Right.

     2.6  Transfer Restrictions.  The Restricted Shares may not be transferred,
          ---------------------
assigned, encumbered, or otherwise disposed of prior to the expiration of the
Repurchase Right, except to a transferee who agrees in writing to be bound by
the provisions of this Section 2 and the Voting Agreement.  Any attempted
transfer of such shares, unless in accordance with this Section 2.6, shall be
void and have no effect.  The Restricted Shares held by a Holder and all of its
transferees of Restricted Shares shall be aggregated for purposes of determining
the number of Warrant Shares subject to the Repurchase Right, and the Company's
Repurchase Right shall apply to each Holder and its transferees of Warrant
Shares on a pro rata basis, based upon the number of Restricted Shares held by
each (without regard to any unexercised shares issuable pursuant to the
Warrant).

     2.7  Legend.  Each certificate representing Restricted Shares shall bear
          ------
the following legend upon its face until such time as the Repurchase Right has
expired:
<PAGE>

                                      -5-

          "THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A

          OF WHICH MAY BE OBTAINED FROM THE SECRETARY OF THE COMPANY), AND
          MAY NOT BE TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT IN
          ACCORDANCE WITH THE AGREEMENT."

     3.   Representations and Warranties of the Company.  The Company hereby
          ---------------------------------------------
represents and warrants to each Investor that, except as set forth on a Schedule
of Exceptions (the "Schedule of Exceptions") furnished each Investor and special

partnership, or similar arrangement.

Investor's representations set forth in Section 4 of this Agreement, the offer,
sale and issuance of the Series A Preferred Stock and Warrants as contemplated

applicable state and federal securities laws, and neither the Company nor any

     3.8  Litigation.  There is no action, suit, proceeding or known
          ----------
investigation pending or, to the Company's knowledge, currently threatened

contemplated hereby or thereby, or that might result, either individually or in
the aggregate, in any material adverse changes in the assets, condition, affairs
or prospects of the Company, financially or otherwise, or any change in the
current equity ownership of the Company, nor is the Company aware that there is
any basis for the foregoing.  The foregoing includes, without limitation,
actions, suits, proceedings or investigations pending or threatened (or any
basis therefor known to the Company) involving the prior employment of any of
the Company's employees, their use in connection with the Company's business of
any information or techniques allegedly proprietary to any of their former
employers, or their obligations under any agreements with prior employers.  The
Company is not a party or subject to the provisions of any order, writ,
injunction, judgment or decree of any court or government agency or
instrumentality.  There is no action, suit, proceeding or investigation by the
Company currently pending or that the Company intends to initiate.

     3.9  Proprietary Information and Shareholders' Agreements.  Each employee
          ----------------------------------------------------
and officer of the Company, and each consultant who has had access to
confidential or proprietary information of the Company, has executed a
Proprietary Information and Inventions Agreement.  Each Founder has executed or
will execute prior to the Closing a Shareholders' Agreement in a form provided
to special counsel to the Investors, which agreement supersedes all prior
agreements between the Company and the Founders related to the capital stock of
the Company held by the Founders.  The Company is not aware that any of its
employees, officers or consultants are in violation thereof, and the Company
will use its best efforts to prevent any such violation.

     3.10 Patents and Trademarks.  The Company has sufficient title and
          ----------------------
ownership of or licenses to all patents, trademarks, service marks, trade names,
copyrights, trade secrets,
<PAGE>

                                      -8-

information, proprietary rights and processes necessary for its business as now
conducted and as proposed to be conducted without any violation or infringement
of the rights of others, except for such items as have yet to be conceived or
developed or that are expected to be available for licensing on reasonable terms
from third parties. The Company has no patents or pending patent applications.
There are no outstanding options, licenses, or agreements of any kind relating
to the foregoing, nor is the Company bound by or a party to any options,
licenses or agreements of any kind with respect to the patents, trademarks,
service marks, trade names, copyrights, trade secrets, licenses, information,
proprietary rights and processes of any other person or entity. The Company has
not received any communications alleging that the Company has violated or, by
conducting its business as proposed, would violate any of the patents,
trademarks, service marks, trade names, copyrights or trade secrets or other
proprietary rights of any other person or entity. The Company is not aware that
any of its employees is obligated under any contract (including licenses,
covenants or commitments of any nature) or other agreement, or subject to any
judgment, decree or order of any court or administrative agency, that would
interfere with the use of his or her best efforts to promote the interests of
the Company or that would conflict with the Company's business as proposed to be
conducted. Neither the execution nor delivery of this Agreement or the
Investors' Rights Agreement or the Ancillary Agreements, nor the carrying on of
the Company's business by the employees of the Company, nor the conduct of the
Company's business as proposed, will, to the best of the Company's knowledge,
conflict with or result in a breach of the terms, conditions or provisions of,
or constitute a default under, any contract, covenant or instrument under which
any of such employees is now obligated. The Company does not believe it is
necessary to utilize any inventions of any of its employees (or people it
currently intends to hire) made prior to or outside the scope of their
employment by the Company.

     3.11  Compliance with Other Instruments. The Company is not in violation or
           ---------------------------------
default of any provision of its Restated Certificate or Bylaws, or of any
instrument, judgment, order, writ, decree or contract to which it is a party or
by which it is bound, or, to the best of its knowledge, of any provision of any
federal or state statute, rule or regulation applicable to the Company. The
execution, delivery and performance of this Agreement and the Investors' Rights
Agreement and the Ancillary Agreements, and the consummation of the transactions
contemplated hereby and thereby will not result in any such violation or be in
conflict with or constitute, with or without the passage of time and giving of
notice, either a default under any such provision, instrument judgment, order,
writ, decree or contract or an event that results in the creation of any lien,
charge or encumbrance upon any assets of the Company or the suspension,
revocation, impairment, forfeiture, or nonrenewal of any material permit,
license, authorization, or approval applicable to the Company, its business or
operations or any of its assets or properties.

Company.

     3.13  Related-Party Transactions.  No employee, officer, or director of the
           --------------------------
Company or member of his or her immediate family is indebted to the Company, nor
is the Company indebted (or committed to make loans or extend or guarantee
credit) to any of them.  To the best of the Company's knowledge, none of such
persons has any direct or indirect ownership interest in any firm or corporation
with which the Company is affiliated or with which the Company has a business
relationship, or any firm or corporation that competes with the Company, except
that employees, officers, or directors of the Company and members of their
immediate families may own stock in publicly traded companies that may compete
with the Company.  No member of the
<PAGE>

                                     -10-

immediate family of any officer or director of the Company is directly or
indirectly interested in any material contract with the Company.

     3.14  Permits.  The Company has all franchises, permits, licenses, and any
           -------
similar authority necessary for the conduct of its business as now being

Company believes it can obtain, without undue burden or expense, any similar

Company is not in default in any material respect under any of such franchises,
permits, licenses, or other similar authority.

relating to the environment or occupational health and safety, and to the best
of its knowledge, no material expenditures are or will be required in order to
comply with any such existing statute, law or regulation.

     3.16  Manufacturing and Marketing Rights.  The Company has not granted
           ----------------------------------
rights to manufacture, produce, assemble, license, market, or sell its products

exclusive right to develop, manufacture, assemble, distribute, market or sell
its products.

     3.17  Disclosure.  The Company has fully provided each Investor with all
           ----------
the information that such Investor has requested for deciding whether to
purchase the Series A Preferred Stock and all information that the Company
believes is reasonably necessary to enable such Investor to make such decision.
Neither this Agreement, the Investors' Rights Agreement, nor any other
statements or certificates made or delivered in connection herewith or therewith
contains any untrue statement of a material fact or omits to state a material
fact necessary to make the statements herein or therein not misleading.

     3.18  Business Plan.  The 1998-1999 Business Plan dated November, 1998,
           -------------
previously delivered to each Investor, has been prepared in good faith by the
Company and does not contain any untrue statement of a material fact nor does it
omit to state a material fact necessary to make the statements made therein not
misleading, except that with respect to projections contained in the Business
Plan, the Company represents only that such projections were prepared in good
faith and that the Company reasonably believes there is a reasonable basis for
such projections.

     3.19  Registration Rights.  Except as provided in the Investors' Rights
           -------------------

rights, including piggyback rights, to any person or entity.

     3.20  Corporate Documents.  Except for amendments necessary to satisfy
           -------------------

assets free and clear of all mortgages, liens, loans and encumbrances, except
such encumbrances and liens that
<PAGE>

                                     -11-

arise in the ordinary course of business and do not materially impair the
Company's ownership or use of such property or assets. With respect to the
property and assets it leases, the Company is in compliance with such leases
and, to the best of its knowledge, holds a valid leasehold interest free of any
liens, claims or encumbrances.

     3.22  Financial Statements.  The Company has delivered to Investor its
           --------------------
unaudited financial statements (balance sheet and statement of operations) as at
and for the eleven (11) month period ended November 30, 1998 (the "Financial
Statements").  The Financial Statements fairly present the financial condition
and operating results of the Company as of the date, and for the periods,
indicated therein, subject to normal year-end audit adjustments.  Except as set
forth in the Financial Statements, the Company has no material liabilities,
contingent or otherwise, other than (i) liabilities incurred in the ordinary
course of business subsequent to November 30, 1998 and (ii) obligations under
contracts and commitments incurred in the ordinary course of business and not
required under generally accepted accounting principles to be reflected in the

are not material to the financial condition or operating results of the Company.
Except as disclosed in the Financial Statements, the Company is not a guarantor
or indemnitor of any indebtedness of any other person, firm or corporation.  The
Company maintains and will continue to maintain a standard system of accounting
established and administered in accordance with generally accepted accounting
principles.

     3.23  Changes.  Since November 30, 1998, there has not been any adverse
           -------
change in the assets, liabilities, financial condition or operating results of
the Company from that reflected in the Financial Statements, except changes in
the ordinary course of business that have not been, in the aggregate, materially
adverse.

     3.24  Employee Benefit Plans.  The Company does not have any Employee
           ----------------------
Benefit Plan as defined in the Employee Retirement Income Security Act of 1974.

     3.25  Tax Returns, Payments and Elections.  The Company has filed all tax
           -----------------------------------
returns and reports (including information returns and reports) as required by
law.  These returns and reports are true and correct in all material respects.
The Company has paid all taxes and other assessments due, except those contested
by it in good faith that are listed in the Schedule of Exceptions.  The
provision for taxes of the Company as shown in the Financial Statements is
adequate for taxes due or accrued as of the date thereof.  The Company has not
elected pursuant to the Internal Revenue Code of 1986, as amended (the "Code"),
to be treated as a Subchapter S corporation pursuant to Section 1362(a) of the
Code, nor has it made an election pursuant to Section 341(f) of the Code, nor
has it made any other elections pursuant to the Code (other than elections that
relate solely to methods of accounting, depreciation or amortization) that would
have a material effect on the Company, its financial condition, its business as
presently conducted or proposed to be conducted or any of its properties or
material assets. The Company has never had any tax deficiency proposed or
assessed against it and has not executed any waiver of any statute of
limitations on the assessment or collection of any tax or governmental charge.
None of the Company's federal income tax returns and none of its state income or
franchise tax or sales or use tax returns has ever been audited by governmental
authorities. Since the date of the Financial Statements, the Company has not
incurred any taxes, assessments or governmental
<PAGE>

                                     -12-

charges other than in the ordinary course of business and the Company has made
adequate provisions on its books of account for all taxes, assessments and
governmental charges with respect to its business, properties and operations for
such period. The Company has withheld or collected from each payment made to
each of its employees, the amount of all taxes (including, but not limited to,

depositories.

subject to) any written or oral, express or implied, contract, commitment or
arrangement with any labor union, and no labor union has requested or, to the
best of the Company's knowledge, has sought to represent any of the employees,
representatives or agents of the Company.  There is no strike or other labor
dispute involving the Company pending, or to the best of the Company's
knowledge, threatened, that could have a material adverse effect on the assets,
properties, financial condition, operating results, or business of the Company
(as such business is presently conducted and as it is proposed to be conducted),
nor is the Company aware of any labor organization activity involving its
employees.  The Company is not aware that any officer or key employee, or that
any group of key employees, intends to terminate their employment with the
Company, nor does the Company have a present intention to terminate the
employment of any of the foregoing.  The employment of each officer and employee
of the Company is terminable at the will of the Company.  To the best of its
knowledge, the Company has complied in all material respects with all applicable
state and federal equal employment opportunity and other laws related to
employment.  The Company is not a party to or bound by any currently effective

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

           ---------
recording, storing, processing, calculating and displaying calendar dates

expected to have a material adverse affect on the assets, properties, financial
condition, operating results or business of the Company.  The foregoing does not
constitute a warranty or representation that the Company's software will be

hereby represents and warrants that:

     4.1   Authorization.  Such Investor has full power and authority to enter
           -------------
into this Agreement, the Investors' Rights Agreement and the Ancillary
Agreements, and each such Agreement constitutes its valid and legally binding
obligation, enforceable in accordance with its terms except (i) as limited by
applicable bankruptcy, insolvency, reorganization, moratorium, and other laws of
general application affecting enforcement of creditors' rights generally, (ii)
as limited by laws relating to the availability of specific performance,
injunctive relief, or other
<PAGE>

                                     -14-

equitable remedies, and (iii) to the extent the indemnification provisions
contained in the Investors' Rights Agreement may be limited by applicable
federal or state securities laws.

     4.2   Purchase Entirely for Own Account.  This Agreement is made with such
           ---------------------------------
Investor in reliance upon such Investor's representation to the Company, which
by such Investor's execution of this Agreement such Investor hereby confirms,
that the Series A Preferred Stock and the Warrant to be received by such
Investor, the Warrant Shares and the Common Stock issuable upon conversion of
the Series A Preferred Stock and the Warrant Shares (collectively, the
"Securities") will be acquired for investment for such Investor's own account,
not as a nominee or agent, and not with a view to the resale or distribution of
any part thereof, and that such Investor has no present intention of selling,
granting any participation in, or otherwise distributing the same.  By executing
this Agreement, such Investor further represents that such Investor does not
have any contract, undertaking, agreement or arrangement with any person to
sell, transfer or grant participations to such person or to any third person,
with respect to any of the Securities.

     4.3   Disclosure of Information.  Such Investor represents that it has had
           -------------------------
an opportunity to ask questions and receive answers from the Company regarding
the terms and conditions of the offering of the Series A Preferred Stock and
Warrant, and the business, properties, prospects and financial condition of the
Company.  The foregoing, however, does not limit or modify the representations
and warranties of the Company in Section 3 of this Agreement or the right of the
Investors to rely thereon.

     4.4   Investment Experience.  Such Investor is an investor in securities of
           ---------------------
companies in the development stage and acknowledges that it is able to fend for
itself, can bear the economic risk of its investment, and has such knowledge and
experience in financial or business matters that it is capable of evaluating the
merits and risks of the investment in the Series A Preferred Stock and Warrant.
If other than an individual, such Investor also represents it has not been
organized for the purpose of acquiring the Series A Preferred Stock or Warrant.

     4.5   Accredited Investor.  Such Investor is an "accredited investor"
           -------------------
within the meaning of Securities and Exchange Commission ("SEC") Rule 501 of
Regulation D, as presently in effect.

     4.6   Restricted Securities.  Such Investor understands that the Securities
           ---------------------
it is purchasing are characterized as "restricted securities" under the federal
securities laws inasmuch as they are being acquired from the Company in a
transaction not involving a public offering and that under such laws and
applicable regulations such securities may be resold without registration under
the Act, only in certain limited circumstances.  In this connection, such
Investor represents that it is familiar with SEC Rule 144, as presently in
effect, and understands the resale limitations imposed thereby and by the Act.

     4.7   Further Limitations on Disposition.  Without in any way limiting the
           ----------------------------------
representations set forth above, such Investor further agrees not to make any
disposition of all or any portion of the Securities unless and until the
transferee has agreed in writing for the benefit of the Company to be bound by
this Section 4 and the Investors' Rights Agreement provided and to the extent
this Section and such agreement are then applicable, and:
<PAGE>

                                     -15-

           (a)  There is then in effect a Registration Statement under the Act
covering such proposed disposition and such disposition is made in accordance
with such Registration Statement; or

           (b)  (i) Such Investor shall have notified the Company of the
proposed disposition and shall have furnished the Company with a detailed
statement of the circumstances surrounding the proposed disposition, and (ii) if
reasonably requested by the Company, such Investor shall have furnished the
Company with an opinion of counsel, reasonably satisfactory to the Company, that
such disposition will not require registration of such shares under the Act. It
is agreed that the Company will not require opinions of counsel for transactions
made pursuant to Rule 144 except in unusual circumstances.

           (c)  Notwithstanding the provisions of Paragraphs (a) and (b) above,
no such registration statement or opinion of counsel shall be necessary for a
transfer by an Investor that is a partnership to a partner of such partnership
or a retired partner of such partnership who retires after the date hereof, or
to the estate of any such partner or retired partner or the transfer by gift,
will or intestate succession of any partner to his or her spouse or to the
siblings, lineal descendants or ancestors of such partner or his or her spouse,
if the transferee agrees in writing to be subject to the terms hereof to the
same extent as if he or she were an original Investor hereunder.
