                                   SECTION 2

                 RESTRICTIONS ON TRANSFERABILITY OF SECURITIES;
                 ----------------------------------------------
                         COMPLIANCE WITH SECURITIES ACT
                         ------------------------------

         2.1  Restrictions on Transferability. The Preferred Stock and the
              -------------------------------
Conversion Shares shall not be transferable except upon the conditions specified
in this Section 2, which conditions are intended to ensure compliance with the
provisions of the Securities Act, or, in the case of Section 2.13 hereof, to
assist in an orderly distribution. Each Investor will cause any proposed
transferee of the Preferred Stock and the Conversion Shares held by such
Investor to agree to take and hold such securities subject to the provisions and
upon the conditions specified in this Section 2 (including the "market
stand-off" provisions of Section 2.13).

         2.2  Restrictive Legend. Each certificate representing (i) the
              ------------------
Preferred Stock, (ii) Conversion Shares and (iii) any other securities issued in
respect of the Preferred Stock or Conversion Shares or Common Stock issuable
upon any stock split, stock combination, stock dividend, recapitalization,
consolidation or similar event, shall (unless otherwise permitted by the
provisions of Section 2.3 below) be stamped or otherwise imprinted with a legend
in substantially the following form (in addition to any legend required under
applicable state securities laws):

     THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
     INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933.
     SUCH SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH
     REGISTRATION OR AN EXEMPTION THEREFROM UNDER SAID ACT. COPIES OF THE
     AGREEMENT COVERING THE PURCHASE OF THESE SHARES AND RESTRICTING THEIR
     TRANSFER MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE HOLDER
     OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE CORPORATION AT THE
     PRINCIPAL EXECUTIVE OFFICE.

         2.3  Notice of Proposed Transfers. The holder of each certificate
              ----------------------------
representing Restricted Securities agrees to comply in all respects with the
provisions of this Section 2.3. Prior to any proposed transfer of any Restricted
Securities (unless there is in effect a registration statement under the
Securities Act covering the proposed transfer), the holder thereof shall give
written notice to the Company of such holder's intention to effect such
transfer. Each such notice

                                       4

<PAGE>

shall describe the manner and circumstances of the proposed transfer in
sufficient detail, and (except in transactions in compliance with Rule 144)
shall be accompanied by either (i) a written opinion of legal counsel who shall
be reasonably satisfactory to the Company addressed to the Company and
reasonably satisfactory in form and substance to the Company's counsel, to the
effect that the proposed transfer of the Restricted Securities may be effected
without registration under the Securities Act, or (ii) a "no action" letter from
the Commission to the effect that the transfer of such securities without
registration will not result in a recommendation by the staff of the Commission
that action be taken with respect thereto, whereupon the holder of such
Restricted Securities shall be entitled to transfer such Restricted Securities
in accordance with the terms of the notice delivered by the holder to the
Company. Each certificate evidencing the Restricted Securities transferred
pursuant to the above shall bear the legend set forth in Section 2.2 above,
except that such certificate shall not bear such restrictive legend, if in the
opinion of counsel for the Company, such legend is not required in order to
establish compliance with any provisions of the Securities Act.

         2.4  Company Registration.
              --------------------

         (a)  Registration. If at any time or from time to time, the Company
              ------------
shall determine to register any of its securities, either for its own account or
the account of a security holder or holders exercising their respective demand
registration rights, other than (i) a registration on Form S-8 (or a similar or
successor form) relating solely to employee stock option, stock purchase or
other benefit plans, or (ii) a registration on Form S-4 (or similar or successor
form) relating solely to a Securities and Exchange Commission Rule 145
transaction, the Company will:

              (i)  promptly give to each Holder written notice thereof; and

              (ii) include in such registration (and any related qualification
under blue sky laws or other compliance), and in any underwriting involved
therein, all the Registrable Securities specified in a written request or
requests, made within twenty (20) days after mailing of written notice by the
Company, by any Holder or Holders, except as set forth in Section 2.4(b) below.

         (b)  Underwriting. If the registration of which the Company gives
              ------------
notice is for a registered public offering involving an underwriting, the
Company shall so advise the Holders as a part of the written notice given
pursuant to Section 2.4(a)(i). In such event the right of any Holder to
registration pursuant to Section 2.4 shall be conditioned upon such Holder's
participation in such underwriting and the inclusion of such Holder's
Registrable Securities in the underwriting to the extent provided herein.

              All Holders proposing to distribute their securities through such
underwriting shall (together with the Company and the other holders distributing
their securities through such underwriting) enter into an underwriting agreement
in customary form with the underwriter or underwriters selected for such
underwriting by the Company. Notwithstanding any other provision of this Section
2.5, if the managing underwriter determines that marketing factors require a
limitation of the number of shares to be underwritten, the underwriter may limit

                                       5

<PAGE>

the number of Registrable Securities to be included in the registration and
underwriting, on a pro rata basis based on the total number of securities
(including, without limitation, Registrable Securities) entitled to registration
pursuant to registration rights granted to the participating Holders by the
Company; provided, however, that no such reduction may reduce the number of
securities being sold by the Company for its own account. The number of
securities includable by any Holder or other person may, in the discretion of
the underwriters, be rounded to the nearest one hundred (100) shares. No
securities excluded from the underwriting by reason of the underwriter's
marketing limitation shall be included in such registration.

         If any Holder disapproves of the terms of any such underwriting, he may
elect to withdraw therefrom by written notice to the Company and the
underwriter. Any securities excluded or withdrawn from such underwriting shall
be withdrawn from such registration.

         If the underwriter has not limited the number of shares to be
underwritten for the Company's account and the account of the Holders, the
Company may include securities for the account of employees, officers, directors
and consultants.

         2.5  S-3 Registrations. If the Company is requested (and qualifies
                  -------------
under applicable SEC rules) to undertake a Form S-3 or equivalent short-form
registration, regardless of its designation, and any related qualification or
compliance, of its securities by the Holders of Registrable Securities holding
in aggregate at least 2% of the Company's Common Stock for an offering estimated
to result in aggregate offering proceeds of at least $500,000, net of
allowances, discounts, and underwriting expenses, the Company shall promptly
give notice of such proposed registration to all Holders of Registrable
Securities and the Company shall, as expeditiously as possible, use its best
efforts to effect the registration on Form S-3 of the Registerable Securities
which the Company has been requested to register (i) in each request and (ii) in
any response given within twenty (20) days to a notice from the Company pursuant
to this Section 2.5. Notwithstanding the foregoing, however, such registration
shall be subject to the following:

         (a)  The Company shall not be required to effect more than one such
registration pursuant to this Section 2.5 in any 12 month period.

         (b)  The Company shall not be required to effect a registration
pursuant to this Section 2.5 within one hundred eighty (180) days of the
effective date of any registration referred to in Section 2.4.

         The Company may include in the registration under this Section 2.5 any
other shares of Common Stock (including issued and outstanding shares of Common
Stock as to which the holders thereof have contracted with the Company for
"piggyback" registration rights) so long as the inclusion in such registration
of such shares will not, in the opinion of the managing underwriter (or in the
reasonable opinion of the Company in the event that the offering is not
underwritten), interfere with the successful marketing in accordance with the
intended method of sale or other disposition of all the shares of Registrable
Securities sought to be registered by the Holder or Holders of Registrable
Securities pursuant to this Section 2.5. If it is determined as provided above
that there will be such interference, the other shares of Common Stock sought to

                                       6

<PAGE>

be included by the Company shall be excluded to the extent deemed necessary by
the managing underwriter (or the Company if the offering is not underwritten),
and all other shares of Common Stock held by other parties shall be excluded
before the exclusion of any shares of Registrable Securities held by the Holders
who desire to have their shares included in the registration and offering. If,
as contemplated above, and after excluding all other shares of Common Stock held
by other parties, shares of the Common Stock of the Holders are to be excluded,
the number of shares of Common Stock of each participating Holder which are to
be excluded shall be proportionate to the number of shares which such party is
seeking to register.

         2.6  Expenses of Registration. All Registration Expenses incurred in
              ------------------------
connection with any registration, qualification or compliance pursuant to this
Section 2 shall be borne by the Company; and, unless otherwise stated, all
Selling Expenses relating to securities registered by the Holders shall be borne
by the Holders of such securities pro rata on the basis of the number of shares
so registered.

         2.7  Registration Procedures. In the case of each registration,
              -----------------------
qualification or compliance effected by the Company pursuant to this Section 2,
the Company will keep each Holder advised in writing as to the initiation of
each registration, qualification and compliance and as to the completion
thereof. At its expense the Company will:

         (a)  Keep such registration, qualification or compliance effective for
a period of one hundred twenty (120) days or until the Holder or Holders have
completed the distribution described in the registration statement relating
thereto, whichever first occurs; and

         (b)  Furnish such number of prospectuses and other documents incident
thereto as a Holder from time to time may reasonably request.

         2.8  Indemnification.
              ---------------

         (a)  The Company will, and does hereby undertake to, indemnify and hold
harmless each Holder, each of its officers, directors and partners, and each
person controlling such Holder within the meaning of Section 15 of the
Securities Act, with respect to which registration, qualification or compliance
has been effected pursuant to this Section 2, and each underwriter, if any, and
each person who controls any underwriter within the meaning of Section 15 of the
Securities Act, against all expenses, claims, losses, damages and liabilities
(or actions in respect thereof), including settlement of any litigation,
commenced or threatened, to which they may become subject under the Securities
Act, the 1934 Act, or other federal or state law, arising out of or based on
compliance with, any untrue statement (or alleged untrue statement) of a
material fact contained in any registration statement, prospectus (preliminary
or final), offering circular or other document or amendments thereto, or arising
out of or based on any omission (or alleged omission) to state therein a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances in which they were made, not misleading,
or arising out of or any violation by the Company of any federal, state or
common law rule or regulation applicable to the Company and relating to action
or inaction required of the Company in connection with any such registration,
qualification or compliance, and will reimburse each such Holder, each of its
officers, directors and partners, and each person

                                       7

<PAGE>

controlling such Holder, each such underwriter and each person who controls any
such underwriter, for any legal and any other expenses reasonably incurred in
connection with investigating, preparing or defending any such claim, loss,
damage, liability or action, provided that the Company will not be liable in any
such case to the extent that any such claim, loss, damage, liability or expense
arises out of or is based on any untrue statement or omission or alleged untrue
statement or omission, made in reliance upon and in conformity with written
information furnished to the Company by an instrument executed by such Holder or
underwriter expressly for use in connection with such registration.

         (b) Each Holder will, if Registrable Securities held by such Holder are
included in the securities as to which such registration, qualification or
compliance is being effected, indemnify and hold harmless the Company, each of
its directors and officers, agents and employees, each underwriter, if any, of
the Company's securities covered by such a registration statement, each person
who controls the Company or such underwriter within the meaning of Section 15 of
the Securities Act, and each other such Holder, each of its officers, directors
and partners and each person controlling such Holder within the meaning of
Section 15 of the Securities Act, against all claims, losses, damages and
liabilities (or actions in respect thereof to which they may become subject)
arising out of or based on any untrue statement (or alleged untrue statement) of
a material fact contained in any such registration statement, prospectus,
offering circular or other document, or amendments thereto, or any omission (or
alleged omission) to state therein a material fact required to be stated therein
in light of the circumstances in which they were made, or necessary to make the
statements therein, not misleading, and will reimburse the Company, such
Holders, such directors, officers, persons, underwriters or control persons for
any legal or any other expenses reasonably incurred in connection with
investigating or defending any such claim, loss, damage, liability or action, in
each case to the extent, but only to the extent, that such untrue statement (or
alleged untrue statement) or omission (or alleged omission) is made in such
registration statement, prospectus, offering circular or other document in
reliance upon and in conformity with written information furnished to the
Company by an instrument executed by such Holder expressly for use in connection
with such registration; provided, however, that the obligations of such Holders
hereunder shall be limited to an amount equal to the proceeds to each such
Holder of Registrable Securities from the sale of such Registrable Securities as
contemplated herein.

         (c) Each party entitled to indemnification under this Section 2.8 (the
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party

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

         3.1   Right.
               -----

         (a)   If, at any time prior to the expiration of the period set forth
in Section 3.6 below, the Company should desire to issue any Securities in a
transaction not registered under the Securities Act, it shall give each Investor
the first right to purchase such Investor's Pro Rata Share (as defined below),
of all of such Securities on the same terms and same price as the Company is
willing to sell such Securities to any other person. Such Investor's "Pro Rata
Share" of the Securities shall be equal to that percentage of the outstanding
Common Stock of the Company held by such Investor, on the date of the Company's
written notification referred to in Section 3.2 below.

         (b)   For purposes of this Section 3.1, the Common Stock of the Company
held by such Investor shall be adjusted for stock dividends, stock splits, stock
combinations, recapitalizations and the like, and shall be deemed to include
shares of Common Stock issued or

                                       10

<PAGE>

issuable upon conversion of the Preferred Stock or any other stock of the
Company on an as-converted basis.

         3.2   Notification. Prior to any sale or issuance by the Company of any
               ------------
Securities, the Company shall notify each Investor, in writing, of its intention
to sell and issue such securities, setting forth in reasonable detail the terms,
price and description under which it proposes to make such sale. Within fifteen

exercises Investor's option and elects to purchase such Investor's Pro Rata
Share (or any part thereof) of the Securities so offered.

         3.3   Waiver. If, within fifteen (15) days after the Company gives
               ------
notice pursuant to Section 3.2 above, the Investor does not notify the Company
that such Investor desires to purchase all of its Pro Rata Share of the
Securities described in such notice upon the terms and conditions set forth
therein, the Company may, during a period of ninety (90) days following the end
of such fifteen (15) day period, sell and issue such Securities as to which
Investor does not indicate a desire to purchase to another person upon the same
terms and conditions as those set forth in the notice to Investor but at a price
at least as great as the price offered to the Investors; provided, that failure
by the Investor to exercise its option to purchase with respect to one offering,
sale and issuance shall not affect its option to purchase Securities in any
subsequent offering, sale and purchase. In the event the Company has not sold
the Securities, or entered into a binding agreement to sell the Securities,
within such ninety (90) day period, the Company shall not thereafter issue or
sell any Securities without first offering such securities to Investor in the
manner provided above.

         3.4   Issuance. If an Investor gives the Company notice that such
               --------
Investor desires to purchase any of the Securities offered by the Company,
payment for the Securities shall be by check or wire transfer, against delivery
of the Securities at the executive offices of the Company within ten (10) days
after giving the Company such notice, or if later, the closing date for the sale
of such Securities. The Company shall take all such action as may be required by
any regulatory authority in connection with the exercise by Investor of the
right to purchase Securities as set forth in this Section 3, but the right of an
Investor is subject to the Company's reasonable compliance with regulatory
requirements.

         3.5   Excluded Securities. The right of first refusal contained in this
               -------------------
Section 3 shall not apply to the following: (a) the issuance by the Company of
(i) up to 6,000,000 shares of Common Stock to officers, directors, or employees
of, or consultants or contractors to, the Company pursuant to a stock grant,
option plan or purchase plan or other stock incentive program approved by the

or descendants or spouse or to a trustee for their benefit; provided, that the
