Item 14. Indemnification of Directors and Officers.

   Section 67 of Chapter 156B of the Massachusetts General Laws, or the
Massachusetts Business Corporation Law (the "MBCL"), provides that the
indemnification of directors, officers, employees and other agents of a
corporation, and persons who serve at its request as directors, officers,
employees or other agents of another organization, or who serve at its request
in any capacity with respect to any employee benefit plan, may be provided by
it to whatever extent shall be specified in or authorized by (i) the articles
of organization or (ii) a by-law adopted by the stockholders or (iii) a vote
adopted by the holders of a majority of the shares of stock entitled to vote on
the election of directors. Except as the articles of organization or by-laws
otherwise require, indemnification of any such persons who are not directors of
the corporation may be provided by it to the extent authorized by the
directors. Such indemnification may include payment by the corporation of
expenses incurred in defending a civil or criminal action or proceeding in
advance of the final disposition of such action or proceeding, upon receipt of
an undertaking by the person indemnified to repay such payment if he shall be
adjudicated not to be entitled to indemnification, which undertaking may be
accepted without reference to the financial ability of such person to make
repayment. Any such indemnification may be provided although the person to be
indemnified is no longer an officer, director, employee or agent of the
corporation or of such other organization or no longer serves with respect to
any such employee benefit plan. Section 67 further provides that no
indemnification shall be provided for any person with respect to any matter as
to which he shall have been adjudicated in any proceeding not to have acted in
good faith in the reasonable belief that his action was in the best interest of
the corporation or, to the extent that such matter relates to service with
respect to any employee benefit plan, in the best interests of the participants
or beneficiaries of such employee benefit plan.

   The Company's by-laws provide that the Company shall indemnify each person
who is, or shall have been, a director, officer, employee or agent of the
Company, or who is serving or shall have served, at the request of the Company,
as a director or officer of another organization or in any capacity with
respect to any employee benefit plan of the Company, against all liabilities
and expenses (including judgments, fines, penalties, amounts paid or to be paid
in settlement and reasonable attorney's fees) imposed upon or incurred by any
such person in connection with or arising out of claims made, or any action,
suit or proceeding threatened or brought against him or in which he may be
involved by reason of any action taken omitted by him as a director, officer,
employee or agent, or as a result of any service with respect to any such
employee benefit plan.

                                      II-1
<PAGE>

   Section 13(b)(1 1/2) of Chapter 156B of the MBCL permits a corporation to
include in its articles of organization a provision eliminating or limiting the
personal liability of a director to the corporation or its stockholders for
monetary damages for breach of fiduciary duty as a director, provided that such
provision shall not eliminate or limit the liability of a director (i) for any
breach of the director's duty of loyalty to the corporation or its
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) under Section 61 or
62 of the MBCL (relating to unlawful payment of dividends, unlawful stock
purchase and redemption and loans to insiders) or (iv) for any transaction from
which the director derived an improper personal benefit. Article VI of the
Company's Articles of Organization provides that the Company's directors shall
not be liable to the Company or its stockholders for monetary damages for
breach of fiduciary duty as a director, expect in the circumstances set forth
in the MBCL.

   Section 67 of the MBCL also affords a Massachusetts corporation the power to
obtain insurance on behalf of its directors and officers against liabilities
incurred by them in those capacities. The Company currently maintains a
directors and officers liability insurance policy.

   The Underwriting Agreement filed as Exhibit 1.1 provides that the
Underwriters named therein will indemnify and hold harmless the Company and
each director, officer or controlling person of the Company from and against
certain liabilities, including liabilities under the Securities Act of 1933, as
amended (the "Securities Act"), and the Underwriting Agreement provides that
such Underwriters will contribute to certain liabilities of such persons under
the Securities Act.

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, 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 that:

     (1) For purposes of determining any liability under the Securities Act,
  the information omitted from the form of prospectus filed as part of this
  registration statement in reliance on 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 is declared effective.

     (2) 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.

   The undersigned registrant hereby undertakes to provide to the underwriter
at the closing specified in the underwriting agreement certificates in such
denominations and registered in such names as required by the underwriter to
permit prompt delivery to each purchaser.

          class of stock which may at any time be authorized or issued, or any

series, and/or may decrease (but not below the number of shares thereof then
outstanding) the number of shares of any class or series of Preferred Stock
already created by providing that any unissued shares previously assigned to

     Section 3.  Residual Rights.  All rights accruing to the outstanding shares
     ---------   ---------------
of capital stock of the corporation not expressly provided for to the contrary
in the Restated Articles of Organization with respect to the existing class or
series of Preferred Stock or in any subsequent designations with respect to any
other class or series of Preferred Stock shall be vested in the Common Stock.

                            CLASS A PREFERRED STOCK
                            -----------------------

     Section 1.  Designation.  Three Million Ninety Thousand Three Hundred
     ---------   -----------
Twenty-Three (3,090,323) shares of Preferred Stock are hereby designated as
"Class A Preferred Stock" (the "Class A Preferred").

     Section 2.  Liquidation Rights.  In the event of any voluntary or
     ---------   ------------------
involuntary liquidation, dissolution or winding up of the affairs of the
corporation, the holders of each share of Class A Preferred shall be entitled to
receive, prior and in preference to any distribution of any of the assets or
surplus funds of the corporation to the holders of the Class C Preferred and the
holders of the Common Stock of the corporation by reason of their ownership
thereof, an amount equal to three dollars and twenty-five cents ($3.25) per
share plus an amount equal to all declared but unpaid dividends to and including
the date full payment shall be tendered to the holder of the Class A Preferred
with respect to such liquidation, dissolution or winding up.

     All of the preferential amounts to be paid to the holders of the Class A
Preferred under this Section 2 shall be paid or set apart for payment before the
payment or setting apart for payment of any amount for, or the distribution of
any assets of the corporation to, the holders of

                                       4
<PAGE>

the Class C Preferred or the holders of the Common Stock in connection with such
liquidation, dissolution or winding up. After the payment or the setting apart
of payment to the holders of the Class A Preferred of the preferential amounts
so payable to them, the holders of the Class C Preferred and the holders of the
Common Stock shall be entitled to receive all remaining assets of the
corporation.

     If the assets or surplus funds to be distributed to the holders of the
Class A Preferred are insufficient to permit the payment to such holders of
their full preferential amount, the assets and surplus funds legally available
for distribution shall be distributed ratably among the holders of the Class A
Preferred in proportion to the full preferential amount each such holder is
otherwise entitled to receive.

     A consolidation or merger of the corporation or a sale of all or
substantially all of the assets of the corporation shall be regarded as a
liquidation, dissolution or winding up of the affairs of the corporation within
the meaning of this Section 2; provided, however, that each holder of Class A
                               --------  -------
Preferred shall have the right to elect the benefits of the provisions of
Section 3(d) (vii) hereof in lieu of receiving payment in liquidation,
dissolution or winding up of the corporation pursuant to this Section 2.

     Section 3.  Conversion.  The holders of the Class A Preferred shall have
     ---------   ----------
conversion rights as follows (the "Conversion Rights"):

          (a)  Right to Convert.  Each share of Class A Preferred shall be
               ----------------
convertible, without the payment of any additional consideration by the holder
thereof and at the option of the holder thereof, at any time after the date of
issuance of such share, at the office of the corporation or any transfer agent
for the Class A Preferred, into such number of fully paid and nonassessable
shares of Common Stock as is determined by dividing three dollars and
twenty-five cents ($3.25) by the Conversion Price, determined as hereinafter
provided, in effect at the time of conversion. The Conversion Price at which
shares of Common Stock shall be deliverable upon conversion without the payment
of any additional consideration by the holder thereof (the "Conversion Price")
shall initially be three dollars and twenty-five cents ($3.25) per share of
Common Stock. Such initial Conversion Price shall be subject to adjustment, in
order to adjust the number of shares of Common Stock into which the Class A
Preferred is convertible, as hereinafter provided.

          (b)  Automatic Conversion.  Each share of Class A Preferred shall
               --------------------
automatically be converted into shares of Common Stock at the then effective
Conversion Price upon the closing of a firm commitment underwritten public
offering pursuant to an effective registration statement under the Securities
Act of 1933, as amended, covering the offer and sale of Common Stock for the
account of the corporation to the public at a public offering price of at least
$4.50 per share (with such amount to be appropriately adjusted in the event of
any stock dividend, stock distribution or subdivision as provided in
subparagraph (d)(vi) hereof) and having an aggregate offering price to the
public resulting in gross proceeds to the corporation of not less than
$15,000,000 (in the event of which offering, the person(s) entitled to receive
the Common Stock issuable upon such conversion of the Class A Preferred shall
not be deemed to have converted that Class A Preferred until immediately prior
to the closing of such offering).

                                       5
<PAGE>

Each person who holds of record Class A Preferred immediately prior to such
automatic conversion shall be entitled to all dividends which have accrued to
the time of the automatic conversion, but not paid on the Class A Preferred,
pursuant to Section 6 hereof. Such dividends shall be paid to all such holders
within 30 days of the automatic conversion.

          (c)  Mechanics of Conversion.  No fractional shares of Common Stock
               -----------------------
shall be issued upon conversion of the Class A Preferred. In lieu of any
fractional shares to which the holder would otherwise be entitled, the
corporation shall pay cash equal to such fraction multiplied by the then
effective Conversion Price. Before any holder of Class A Preferred shall be
entitled to convert the same into full shares of Common Stock, he shall
surrender the certificate or certificates therefor, duly endorsed, at the office
of the corporation or of any transfer agent for the Class A Preferred, and shall
give written notice to the corporation at such office that he elects to convert
the same and shall state therein his name or the name or names of his nominees
in which he wishes the certificate or certificates for shares of Common Stock to
be issued. The corporation shall, as soon as practicable thereafter, issue and
deliver at such office to such holder of Class A Preferred, or to his nominee or
nominees, a certificate or certificates for the number of shares of Common Stock
to which he shall be entitled as aforesaid, together with cash in lieu of any
fraction of a share. 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 Class A Preferred to be converted, and the person or persons entitled
to receive the shares of Common Stock issuable upon conversion shall be treated
for all purposes as the record holder or holders of such shares of Common Stock
on such date.

          (d)  Adjustments to Conversion Price for Diluting Issues.

               (i)  Special Definitions.  For purposes of this Section 3(d), the
                    -------------------
following definitions shall apply:

                    (1)  "Option" shall mean rights, options, or warrants to
                          ------
subscribe for, purchase or otherwise acquire either Common Stock or Convertible
Securities.

                    (2)  "Original Issue Date" shall mean the date on which a
share of Class A Preferred was first issued.

                    (3)  "Convertible Securities" shall mean any evidences of
indebtedness, shares (other than Common Stock, Class A Preferred or Class B
Preferred) or other securities directly or indirectly convertible into or
exchangeable for Common Stock.

                    (4)  "Additional Shares of Common Stock" shall mean all
shares of Common Stock issued (or, pursuant to Section 3(d)(iii) hereof, deemed
to be issued) by the corporation after the Original Issue Date, other than
shares of Common Stock issued or issuable:

                         (A)  upon conversion of shares of Class A Preferred or
of Class B Preferred;

                                       6
<PAGE>

                         (B)  to officers or employees of, or consultants to,
the corporation pursuant to the corporation's 1983 Incentive Stock Option Plan,
1984 Incentive Stock Option Plan, 1986 Incentive Stock Option Plan, 1987 Stock
Plan, 1988 Stock Plan, 1996 Stock Plan or pursuant to action by the Board of
Directors prior to March 28, 1984, and pursuant to a stock purchase or option
plan or other employee or director stock incentive or compensation program
(collectively, the "Plans") approved by a majority of the representatives of the
Class A Preferred on the Board of Directors;

                         (C)  by way of dividend or other distribution of shares
of Common Stock excluded from the definition of Additional Shares of Common
Stock by the foregoing clauses (A) and (B) or this clause (C) or on shares of
Common Stock so excluded; or

                         (D)  with the approval of a majority of the
representatives of the Class A Preferred and Class B Preferred on the Board of
Directors, which shares have been designated by said majority to be excepted
from the definition of "Additional Shares of Common Stock" contained herein.

               (ii)  No Adjustment of Conversion Price. No adjustment in the
                     ---------------------------------
number of shares of Common Stock into which the Class A Preferred is convertible
shall be made, by adjustment in the Conversion Price of Class A Preferred in
respect of the issuance of Additional Shares of Common Stock or otherwise,
unless the consideration per share for an Additional Share of Common Stock
issued or deemed to be issued by the corporation is less than the Conversion
Price in effect on the date of, and immediately prior to, the issue of such
Additional Share.

               (iii) Issue of Securities Deemed Issue of Additional Shares of
                     --------------------------------------------------------
Common Stock.
- ------------

                     (1) Options and Convertible Securities. In the event the
                         ----------------------------------
corporation at any time or from time to time after the Original Issue Date shall
issue any Options or Convertible Securities or shall fix a record date for the
determination of holders of any class of securities entitled to receive any such
Options or Convertible Securities, then the maximum number of shares (as set
forth in the instrument relating thereto without regard to any provisions
contained therein for a subsequent adjustment of such number) of Common Stock
issuable upon the exercise of such Options or, in the case of Convertible
Securities and Options therefor, the conversion or exchange of such Convertible
Securities, shall be deemed to be Additional Shares of Common Stock issued as of
the time of such issue or, in case such record date shall have been fixed, as of
the close of business on such record date, provided that Additional Shares of
Common Stock shall not be deemed to have been issued unless the consideration
per share (determined pursuant to Section 3(d)(v) hereof), of such Additional
Shares of Common Stock would be less than the Conversion Price in effect on the
date of and immediately prior to such issue, or such record date, as the case
may be, and provided further that in any such case in which Additional Shares of
Common Stock are deemed to be issued:

                                       7
<PAGE>

                         (A)  no further adjustment in the Conversion Price
shall be made upon the subsequent issue of Convertible Securities or shares of
Common Stock upon the exercise of such Options or conversion or exchange of such
Convertible Securities;

                         (B)  if such Options or Convertible Securities by their
terms provide, with the passage of time or otherwise, for any increase in the
consideration payable to the corporation, or decrease in the number of shares of
Common Stock issuable, upon the exercise, conversion or exchange thereof, the
Conversion Price computed upon the original issue thereof (or upon the
occurrence of a record date with respect thereto), and any subsequent
adjustments based thereon, shall, upon any such increase or decrease becoming
effective, be re-computed to reflect such increase or decrease insofar as it
affects such Options or the rights of conversion or exchange under such
Convertible Securities;

                         (C)  upon the expiration of any such Options or any
rights of conversion or exchange under such Convertible Securities which shall
not have been exercised, the Conversion Price computed upon the original issue
thereof (or upon the occurrence of a record date with respect thereto), and any
subsequent adjustments based thereon, shall, upon such expiration, be
re-computed as if:

                              (I)  in the case of Convertible Securities or
Options for Common Stock, the only Additional Shares of Common Stock issued were
the shares of Common Stock, if any, actually issued upon the exercise of such
Options or the conversion or exchange of such Convertible Securities and the
consideration received therefor was the consideration actually received by the
corporation for the issue of all such Options, whether or not exercised, plus
the consideration actually received by the corporation upon such exercise, or
for the issue of all such Convertible Securities which were actually converted
or exchanged, plus the additional consideration, if any, actually received by
the corporation upon such conversion or exchange, and

                              (II) in the case of Options for Convertible
Securities, only the Convertible Securities, if any, actually issued upon the
exercise thereof were issued at the time of issue of such Options, and the
consideration received by the corporation for the Additional Shares of Common
Stock deemed to have been then issued was the consideration actually received by
the corporation for the issue of all such Options, whether or not exercised,
plus the consideration deemed to have been received by the corporation
(determined pursuant to Section 3(d)(v) hereof) upon the issue of the
Convertible Securities with respect to which such Options were actually
exercised;

                         (D)  no readjustment pursuant to clause (B) or (C)
above shall have the effect of increasing the Conversion Price to an amount
which exceeds the lower of (i) the Conversion Price on the original adjustment
data, or (ii) the Conversion Price that would have resulted from any issuance of
Additional Shares of Common Stock between the original adjustment date and such
readjustment date;

                                       8
<PAGE>

                         (E)  in the case of any Options which expire by their
terms not more than 30 days after the date of issue thereof, no adjustment of
the Conversion Price shall be made until the expiration or exercise of all such
Options, whereupon such adjustment shall be made in the same manner provided in
clause (C) above; and

                         (F)  if such record date shall have been fixed and such
Options or Convertible Securities are not issued on the date fixed therefor, the
adjustment previously made in the Conversion Price which became effective on
such record date shall be canceled as of the close of business on such record
date, and thereafter the Conversion Price shall be adjusted pursuant to this
subparagraph 3(d)(iii) as of the actual date of their issuance.

                    (2)  Stock Dividends, Stock Distributions and Subdivisions.
                         -----------------------------------------------------
In the event the corporation at any time or from time to time after the Original
Issue Date shall declare or pay any dividend or make any other distribution on
the Common Stock payable in Common Stock, or effect a subdivision of the
outstanding shares of Common Stock (by reclassification or otherwise than by
payment of a dividend in Common Stock), then and in any such event, Additional
Shares of Common Stock shall be deemed to have been issued:

                         (A)  in the case of any such dividend or distribution,
immediately after the close of business on the record date for the determination
of holders of any class of securities entitled to receive such dividend or
distribution, or

                         (B)  in the case of any such subdivision, at the close
of business on the date immediately prior to the date upon which such corporate
action becomes effective.

     If such record date shall have been fixed and such dividend shall not have
been fully paid on the date fixed therefor, the adjustment previously made in
the Conversion Price which became effective on such record date shall be
canceled as of the close of business on such record date, and thereafter the
Conversion Price shall be adjusted pursuant to this subparagraph 3(d)(iii) as of
the time of actual payment of such dividend.

               (iv) Adjustment of Conversion Price Upon Issuance of Additional
                    ----------------------------------------------------------
Shares of Common Stock. In the event the corporation shall issue Additional
- ----------------------
Shares of Common Stock (including Additional Shares of Common Stock deemed to be
issued pursuant to Section 3(d) (iii) hereof, but excluding Additional Shares of
Common Stock issued pursuant to Section 3(d)(iii)(2), which event is dealt with
in Section 3(d)(vi) hereof) without consideration or for a consideration per
share less than the Conversion Price in effect on the date of and immediately
prior to such issue, then and in such event, such Conversion Price shall be
reduced, concurrently with such issue in order to increase the number of shares
of Common Stock into which the Class A Preferred is convertible, to a price
(calculated to the nearest cent) determined by multiplying such Conversion Price
by a fraction (x) the numerator of which shall be (1) the number of shares of
Common Stock outstanding immediately prior to such issue (including shares of
Common Stock issuable upon conversion of any outstanding Class A Preferred,
Class B Preferred or Convertible Securities), plus (2) the number of shares of
Common Stock which the aggregate

                                       9
<PAGE>

consideration received by the corporation for the total number of Additional
Shares of Common Stock so issued would purchase at such Conversion Price, and
(y) the denominator of which shall be (1) the number of shares of Common Stock
outstanding immediately prior to such issue (including shares of Common Stock
issuable upon conversion of any outstanding Class A Preferred, Class B Preferred
or Convertible Securities), plus (2) the number of such Additional Shares of
Common Stock so issued, provided that the Conversion Price shall not be so
reduced at such time if the amount of such reduction would be an amount less
than $0.05, but any such amount shall be carried forward and reduction with
respect thereto made at the time of and together with any subsequent reduction
which, together with such amount and any other amount or amounts so carried
forward, shall aggregate $0.05 or more.

               (v)  Determination of Consideration.  For purposes of this
                    ------------------------------
Section 3(d), the consideration received by the corporation for the issue of any
Additional Shares of Common Stock shall be computed as follows:

                    (1)  Cash and Property.  Such consideration shall:
                         -----------------

                         (A)  insofar as it consists of cash, be computed at the
aggregate amount of cash received by the corporation excluding amounts paid or
payable for accrued interest or accrued dividends;

                         (B)  insofar as it consists of property other than
cash, be computed at the fair value thereof at the time of such issue, as
determined in good faith by the Board of Directors; and

                         (C)  in the event Additional Shares of Common Stock are
issued together with other shares or securities or other assets of the
corporation for consideration which covers both, be the proportion of such
consideration so received, computed as provided in clauses (A) and (B) above, as
determined in good faith by the Board of Directors.

                    (2)  Options and Convertible Securities.  The consideration
                         ----------------------------------
per share received by the corporation for Additional Shares of Common Stock
deemed to have been issued pursuant to Section 3(d)(iii)(1) above, relating to
Options and Convertible Securities shall be determined by dividing

                         (x)  the total amount, if any, received or receivable
by the corporation as consideration for the issue of such Options or Convertible
Securities, plus the minimum aggregate amount of additional consideration (as
set forth in the instruments relating thereto, without regard to any provision
contained therein for a subsequent adjustment of such consideration until such
subsequent adjustment occurs) payable to the corporation upon the exercise of
such Options or the conversion or exchange of such Convertible Securities, or in
the case of Options for Convertible Securities, the exercise of such Options for
Convertible Securities and the conversion or exchange of such Convertible
Securities, by

                                       10
<PAGE>

                         (y)  the maximum number of shares of Common Stock (as
set forth in the instruments relating thereto, without regard to any provision
contained therein for a subsequent adjustment of such number until such
subsequent adjustment occurs) issuable upon the exercise of such Options or the
conversion or exchange of such Convertible Securities.

               (vi) Adjustment for Dividends, Distributions, Subdivisions,
                    ------------------------------------------------------
Combinations or Consolidation of Common Stock.
- ---------------------------------------------

                    (1)  Stock Dividends, Distributions or Subdivisions.  In the
                         ----------------------------------------------
event the corporation shall issue Additional Shares of Common Stock pursuant to
Section 3(d)(iii)(2) hereof in a stock dividend, stock distribution or
subdivision, the Conversion Price in effect immediately prior to such stock
dividend, stock distribution or subdivision shall, concurrently with the
effectiveness of such stock dividend, stock distribution or subdivision, be
proportionately decreased.

                    (2)  Combination or Consolidations.  In the event the
                         -----------------------------
outstanding shares of Common Stock shall be combined or consolidated, by
reclassification or otherwise, into a lesser number of shares of Common Stock,
the Conversion Price in effect immediately prior to such combination or
consolidation shall, concurrently with the effectiveness of such combination or
consolidation, be proportionately increased.

               (vii) Adjustment for Merger or Reorganization.  In case of any
                     ---------------------------------------
consolidation or merger of the corporation with or into another corporation or
the conveyance of all or substantially all of the assets of the corporation to
another corporation, each share of Class A Preferred 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 Class A Preferred would have been entitled
upon such consolidation, merger or conveyance; and, in any such case,
appropriate adjustment (as determined by the Board of Directors) shall be made
in the application of the provisions herein set forth with respect to the rights
and interest thereafter of the holders of the Class A Preferred, to the end that
the provisions set forth herein (including provisions with respect to changes in
and other adjustments of the Conversion Price) shall thereafter be applicable,
as nearly as reasonably may be, in relation to any shares of stock or other
property thereafter deliverable upon the conversion of the Class A Preferred.

     Each holder of Class A Preferred upon the occurrence of a capital
reorganization, merger or consolidation of the corporation or the sale of all or
substantially all its assets and properties as such events are more fully set
forth in the first paragraph of this Section 3(d)(vii), shall have the option of
electing treatment of his shares of Class A Preferred under either this
Section 3(d)(vii) or Section 2 hereof, notice of which election shall be
submitted in writing to the corporation at its principal offices no later than
five (5) days before the effective date of such event.

          (e)  No Impairment.  The corporation will not, by amendment of its
               -------------
Restated Articles of Organization or through any reorganization, transfer of
assets, consolidation, merger, dissolution, issue or sale of securities or any
other voluntary action, avoid or seek to avoid the

                                       11
<PAGE>

observance or performance of any of the terms to be observed or performed
hereunder by the 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 Class A Preferred against impairment.

          (f)  Certificate as to Adjustments.  Upon the occurrence of each
               -----------------------------
adjustment or readjustment of the Conversion Price pursuant to this Section 3,
the corporation at its expense shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and furnish to each holder of
Class A Preferred a certificate setting forth such adjustment or readjustment
and showing in detail the facts upon which such adjustment or readjustment is
based.  The corporation shall, upon the written request at any time of any
holder of Class A Preferred, furnish or cause to be furnished to such holder a
like certificate setting forth (i) such adjustments and readjustments, (ii) the
Conversion Price at the time in effect, and (iii) the number of shares of Common
Stock and the amount, if any, of other property which at the time would be
received upon the conversion of Class A Preferred.

          (g)  Notice of Record Date.  In the event of (i) any taking by the
               ---------------------
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 which is the same as cash dividends paid in
previous quarters) or other distribution, or (ii) any capital reorganization of
the corporation, any reclassification or recapitalization of the capital stock
of the corporation, any merger or consolidation of the corporation, and any
transfer of all or substantially all of the assets of the corporation to any
other corporation, or any other entity or person, or any voluntary or
involuntary dissolution, liquidation or winding up of the corporation, the
corporation shall mail to each holder of Class A Preferred at least 20 days
prior to the record date specified therein, a notice specifying (A) the date on
which any such record is to be taken for the purpose of such dividend or
distribution and a description of such dividend or distribution, (B) the date on
which any such reorganization, reclassification, transfer, consolidation,
merger, dissolution, liquidation or winding up is expected to become effective,
and (C) the time, if any, that is to be fixed, as to when the holders of record
of Common Stock (or other securities) shall be entitled to exchange their shares
of Common Stock (or other securities) for securities or other property
deliverable upon such reorganization, reclassification, transfer, consolidation,
merger, dissolution, liquidation or winding up.

          (h)  Common Stock Reserved.  The corporation shall reserve and keep
               ---------------------
available out of its authorized but unissued Common Stock such number of shares
of Common Stock as shall from time to time be sufficient to effect conversion of
the Class A Preferred.

     Section 4.  Redemption.  (a) There shall be a five-year period (the
     ---------   ----------
"Redemption Period") for each share of the Class A Preferred commencing five
years after April 20, 1994 for any Class A Preferred issued on or prior to that
date and commencing five years after the date of issuance for any Class A
Preferred issued subsequent to April 20, 1994.  On the commencement date of the
Redemption Period for each share of the Class A Preferred eligible for
redemption and on the first, second, third and fourth anniversaries thereof, the
corporation shall offer to each holder of shares of Class A Preferred eligible
for redemption to redeem a maximum of twenty percent

                                       12
<PAGE>

(20%), forty percent (40%), sixty percent (60%), eighty percent (80%) and one
hundred percent (100%), respectively, of the total number of shares of Class A
Preferred held by such holder prior to the commencement of the Redemption Period
with respect to such Class A Preferred, at a price of three dollars and twenty-
five cents ($3.25) per share, plus an amount equal to all declared but unpaid
dividends payable in accordance with Section 6 hereof on each share of Class A
Preferred tendered for redemption; provided, that any shares of Class A
Preferred redeemed hereunder in any previous years shall reduce the maximum
amount of Class A Preferred which the corporation may be requested to redeem in
any then current year. The corporation shall offer to redeem shares of Class A
Preferred eligible for redemption by giving written notice thereof to each
holder of shares of Class A Preferred eligible for redemption, which notice
shall state the number of shares of Class A Preferred eligible to be redeemed by
such holder and shall specify a redemption date not less than forty-five (45)
days nor more than sixty (60) days after the date of such written notice. Any
holder of shares of Class A Preferred eligible to be redeemed may redeem such
shares by giving written notice thereof to the corporation, and to each other
holder of shares of Class A Preferred, no less than 15 days prior to the
redemption date specified in the corporation's written offer of redemption, and
by surrendering to the corporation on or before the redemption date the share
certificates for the number of shares of Class A Preferred to be redeemed. If
less than all of the shares represented by such certificates are redeemed, a new
certificate shall be issued for the unredeemed shares as promptly as possible.
Notwithstanding the foregoing, the holders of sixty-six and two-thirds percent
(66 2/3%) or more of the Class A Preferred shall have the right to postpone for
a specified period of time or waive such rights of redemption of all holders by
written notice to the corporation and to all such holders given at least fifteen
(15) days prior to the scheduled date of redemption.

          (b)  In the event of a sale of all or substantially all the assets of
the corporation, then the corporation shall offer to each holder of shares of
Class A Preferred to redeem not less than all the shares of Class A Preferred
held by such holder on the date the corporation fixes as the date to mail or
otherwise send out its offer of redemption, at a redemption price of three
dollars and twenty-five cents ($3.25) per shares plus an amount equal to all
declared but unpaid dividends payable in accordance with Section 6 hereof on
each such share of Class A Preferred tendered for redemption. The corporation
shall offer to redeem shares of Class A Preferred by giving written notice
thereof to each holder of shares of Class A Preferred, which notice shall be
sent not less than twenty (20) days before the scheduled date of consummation of
the transaction described above. Such notice of redemption shall state the
number of shares of Class A Preferred eligible to be redeemed by such holder and
shall specify a redemption date not less than twenty (20) days nor more than
sixty (60) days after the date of such written notice. Any holder of shares of
Class A Preferred may redeem such shares by giving written notice thereof to the
corporation not less than ten (10) days prior to the redemption date specified
in the corporation's written offer of redemption, and by surrendering to the
corporation on or before the redemption date the share certificates for the
number of shares of Class A Preferred to be redeemed.

     Section 5.  Voting Rights.
     ---------   -------------

          (a)  The holders of shares of Class A Preferred shall be entitled to
notice of any shareholders' meeting and to vote upon any matter submitted to a
shareholder for a vote, as though the Common Stock, the Class A Preferred, the
Class B Preferred and the Class C Preferred constitute a single class of stock,
except with respect to those matters on which the Massachusetts Corporation Law
requires that a vote must be by a separate class or classes or by separate
series. For all votes other than votes by a separate class or series, holders of
Class A Preferred shall have that number of votes per share as is equal to the
number of shares of Common Stock into which each such share of Class A Preferred
held by such holder is then convertible, provided, however, that at any time, if
the number of shares of Common Stock into which the Class A Preferred is
convertible is increased as a result of an adjustment of the Conversion Price,
all as set forth in Section 3 above, the holders of Class A Preferred shall have
that number of votes equal to the number of shares of Common Stock into which
such Class A Preferred is convertible.

          (b)  The holders of Class A Preferred, the holders of Class B
Preferred, the holders of the Class C Preferred and the holders of Common Stock
shall be entitled to vote upon the election of directors on the following basis:
So long as at least 50,000 shares of Class A Preferred and Class B Preferred,
collectively, shall be outstanding, the holders of Class A Preferred and Class B
Preferred issued and outstanding, voting as a single class, are entitled to
elect three directors; and the holders of Class A Preferred, Class B Preferred,
Class C Preferred and Common Stock and any other capital stock having voting
rights are entitled to elect all other members of the Board of Directors.

     Section 6.  Dividend Rights.
     ---------   ---------------

          (a)  The holders of the then outstanding shares of Class A Preferred
shall be entitled to receive, when and as declared by the Board Directors, out
of funds legally available therefor, non-cumulative cash dividends at the annual
rate of $.26 per share payable at a rate of $.065 per share per calendar
quarter. The corporation's obligation to pay such dividends shall commence after
the first calendar quarter when the corporation's net after tax income,
calculated in accordance with generally accepted accounting principles, exceeds
five times such quarterly dividend on all then outstanding Class A Preferred,
Class B Preferred and Class C Preferred and on all then outstanding shares of
any other class of preferred stock of the corporation.

          (b)  Notwithstanding any provisions in Section 6(a) hereof, dividends
which have been declared on the Class A Preferred but not been paid prior to an
automatic conversion pursuant to Section 3(b) hereof shall be payable within 30
days of the Closing, as defined in Section 3(b), to each person who holds of
record Class A Preferred immediately prior to the automatic conversion.

     Section 7.  Covenants.  So long as at least 50,000 shares of Class A
     ---------   ---------
Preferred shall be outstanding (as adjusted for all subdivisions and
combinations), the corporation shall not,

                                       14
<PAGE>

without first obtaining the affirmative vote or written consent of not less than
sixty-six percent (66%) of such outstanding shares of Class A Preferred:

          (a)  amend or repeal any provision of, or add any provision to, the
corporation's Restated Articles of Organization or By-Laws if such action would
alter or change the preferences, rights, privileges or powers of, or the
restrictions provided for the benefit of, the Class A Preferred generally except
with respect to any class or any series of preferred stock of the corporation
created by the Board of Directors pursuant to a Certificate of Designation in
accordance with the provisions of these Revised Articles of Organization so long
as shares of the class or series created do not have any preference or priority
as to dividends or assets superior to the Class A Preferred;

          (b)  reclassify any Common Stock into shares having any preference or
priority as to dividends or assets superior to or on a parity with any such
preference or priority of the Class A Preferred;

          (c)  pay or declare any dividend or distribution on any shares of
Common Stock or apply any of its assets to the redemption, retirement, purchase
or other acquisition directly or indirectly, through subsidiaries, if any, or
otherwise, of any shares of Common Stock except from officers, directors or
employees of or consultants to the corporation upon termination of employment
and except pursuant to the corporation's rights of first refusal; or

          (d)  create any other class or classes of stock or series of preferred
stock having any preference or priority as to dividends or assets superior to
any such preference or priority of the Class A Preferred; or

          (e)  authorize any merger or consolidation of the corporation with or
into any other corporation or entity (except into or with a wholly-owned
subsidiary corporation with the requisite shareholder approval), or authorize
the sale of substantially all of the assets of the corporation.

                            CLASS B PREFERRED STOCK
                            -----------------------

     Section 1.  Designation.  Seven Hundred Eighty-Nine Thousand Six Hundred
     ---------   -----------
Seventy-Seven (789,677) shares of Preferred Stock are hereby designated as
"Class B Preferred Stock" (the "Class B Preferred").

     Section 2.  Liquidation Rights.  In the event of any voluntary or
     ---------   ------------------
involuntary liquidation, dissolution or winding up of the affairs of the
corporation, the holders of each share of Class B Preferred shall be entitled to
receive, prior and in preference to any distribution of any of the assets or
surplus funds of the corporation to the holders of the Class A Preferred, the
holders of the Class C Preferred and the holders of the Common Stock of the
corporation by reason of their ownership thereof, an amount equal to three
dollars and twenty-five cents ($3.25) per share plus an amount equal to all
declared but unpaid dividends to and including the date full payment shall

                                       15
<PAGE>

be tendered to the holder of the Class B Preferred with respect to such
liquidation, dissolution or winding up.

     All of the preferential amounts to be paid to the holders of the Class B
Preferred under this Section 2 shall be paid or set apart for payment before the
payment or setting apart for payment of any amount for, or the distribution of
any assets of the corporation to, the holders of the Class A Preferred, the
holders of the Class C Preferred or the holders of the Common Stock in
connection with such liquidation, dissolution or winding up. After the payment
or the setting apart of payment to the holders of the Class B Preferred of the
preferential amounts so payable to them, the holders of the Class A Preferred,
the holders of the Class C Preferred and the holders of the Common Stock shall
be entitled to receive all remaining assets of the corporation.

     If the assets or surplus funds to be distributed to the holders of the
Class B Preferred are insufficient to permit the payment to such holders of
their full preferential amount, the assets and surplus funds legally available
for distribution shall be distributed ratably among the holders of the Class B
Preferred in proportion to the full preferential amount each such holder is
otherwise entitled to receive.

     A consolidation or merger of the corporation or a sale of all or
substantially all of the assets of the corporation shall be regarded as a
liquidation, dissolution or winding up of the affairs of the corporation within
the meaning of this Section 2; provided, however, that each holder of Class B
                               --------  -------
Preferred shall have the right to elect the benefits of the provisions of
Section 3(d)(vii) hereof in lieu of receiving payment in liquidation,
dissolution or winding up of the corporation pursuant to this Section 2.

     Section 3.  Conversion.  The holders of the Class B Preferred shall have
     ---------   ----------
conversion rights as follows (the "Conversion Rights"):

          (a)  Right to Convert.  Each share of Class B Preferred shall be
               ----------------
convertible, without the payment of any additional consideration by the holder
thereof and at the option of the holder thereof, at any time after the date of
issuance of such share, at the office of the corporation or any transfer agent
for the Class B Preferred, into such number of fully paid and nonassessable
shares of Common Stock as is determined by dividing three dollars and twenty-
five cents ($3.25) by the Conversion Price, determined as hereinafter provided,
in effect at the time of conversion.  The Conversion Price at which shares of
Common Stock shall be deliverable upon conversion without the payment of any
additional consideration by the holder thereof (the "Conversion Price") shall
initially be three dollars and twenty-five cents ($3.25) per share of Common
Stock.  Such initial Conversion Price shall be subject to adjustment, in order
to adjust the number of shares of Common Stock into which the Class B Preferred
is convertible, as hereinafter provided.

          (b)  Automatic Conversion.  Each share of Class B Preferred shall
               --------------------
automatically be converted into shares of Common Stock at the then effective
Conversion Price upon the closing of a firm commitment underwritten public
offering pursuant to an effective registration statement under the Securities
Act of 1933, as amended, covering the offer and sale of Common Stock for the
account of the corporation to the public at a public offering price of at

                                       16
<PAGE>

least $4.50 per share (with such amount to be appropriately adjusted in the
event of any stock dividend, stock distribution or subdivision as provided in
subparagraph (d)(vi) hereof) and having an aggregate offering price to the
public resulting in gross proceeds to the corporation of not less than
$15,000,000 (in the event of which offering, the person(s) entitled to receive
the Common Stock issuable upon such conversion of the Class B Preferred shall
not be deemed to have converted that Class B Preferred until immediately prior
to the closing of such offering). Each person who holds of record Class B
Preferred immediately prior to such automatic conversion shall be entitled to
all dividends which have accrued to the time of the automatic conversion, but
not paid on the Class B Preferred, pursuant to Section 6 hereof. Such dividends
shall be paid to all such holders within 30 days of the automatic conversion.

          (c)  Mechanics of Conversion. No fractional shares of Common Stock
               -----------------------
shall be issued upon conversion of the Class B Preferred. In lieu of any
fractional shares to which the holder would otherwise be entitled, the
corporation shall pay cash equal to such fraction multiplied by the then
effective Conversion Price. Before any holder of Class B Preferred shall be
entitled to convert the same into full shares of Common Stock, he shall
surrender the certificate or certificates therefor, duly endorsed, at the office
of the corporation or of any transfer agent for the Class B Preferred, and shall
give written notice to the corporation at such office that he elects to convert
the same and shall state therein his name or the name or names of his nominees
in which he wishes the certificate or certificates for shares of Common Stock to
be issued. The corporation shall, as soon as practicable thereafter, issue and
deliver at such office to such holder of Class B Preferred, or to his nominee or
nominees, a certificate or certificates for the number of shares of Common Stock
to which he shall be entitled as aforesaid, together with cash in lieu of any
fraction of a share. 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 Class B Preferred to be converted, and the person or persons entitled
to receive the shares of Common Stock issuable upon conversion shall be treated
for all purposes as the record holder or holders of such shares of Common Stock
on such date.

          (d)  Adjustments to Conversion Price for Diluting Issues.
               ---------------------------------------------------

               (i)  Special Definitions. For purposes of this Section 3(d), the
                    -------------------
following definitions shall apply:

                    (1)  "Option" shall mean rights, options, or warrants to
                          ------
subscribe for, purchase or otherwise acquire either Common Stock or Convertible
Securities.

                    (2)  "Original Issue Date" shall mean the date on which a
                          -------------------
share of Class B Preferred was first issued.

                    (3)  "Convertible Securities" shall mean any evidences of
                          ----------------------
indebtedness, shares (other than Common Stock, Class A Preferred or Class B
Preferred) or other securities directly or indirectly convertible into or
exchangeable for Common Stock.

<PAGE>

                    (4)  "Additional Shares of Common Stock" shall mean all
                          ---------------------------------
shares of Common Stock issued (or, pursuant to Section 3(d)(iii) hereof, deemed
to be issued) by the corporation after the Original Issue Date, other than
shares of Common Stock issued or issuable:

                         (A)  upon conversion of shares of Class A Preferred or
of Class B Preferred;

                         (B)  to officers or employees of, or consultants to,
the corporation pursuant to the corporation's 1983 Incentive Stock Option Plan,
1984 Incentive Stock Option Plan, 1986 Incentive Stock Option Plan, 1987 Stock
Plan, 1988 Stock Plan, 1996 Stock Plan or pursuant to action by the Board of
Directors prior to March 15, 1991, and pursuant to a stock purchase or option
plan or other employee or director stock incentive or compensation program
(collectively, the "Plans") approved by a majority of the representatives of the
Class A Preferred and Class B Preferred on the Board of Directors;

                         (C)  by way of dividend or other distribution of shares
of Common Stock excluded from the definition of Additional Shares of Common
Stock by the foregoing clauses (A) and (B) or this clause (C) or on shares of
Common Stock so excluded; or

                         (D)  with the approval of a majority of the
representatives of the Class A Preferred and Class B Preferred on the Board of
Directors, which shares have been designated by said majority to be excepted
from the definition of "Additional Shares of Common Stock" contained herein.

               (ii)  No Adjustment of Conversion Price. No adjustment in the
number of shares of Common Stock into which the Class B Preferred is convertible
shall be made, by adjustment in the Conversion Price of Class B Preferred in
respect of the issuance of Additional Shares of Common Stock or otherwise,
unless the consideration per share for an Additional Share of Common Stock
issued or deemed to be issued by the corporation is less than the Conversion
Price in effect on the date of, and immediately prior to, the issue of such
Additional Share.

               (iii) Issue of Securities Deemed Issue of Additional Shares of
                     --------------------------------------------------------
Common Stock.
- ------------

                     (1) Options and Convertible Securities. In the event the
                         ----------------------------------
corporation at any time or from time to time after the Original Issue Date shall
issue any Options or Convertible Securities or shall fix a record date for the
determination of holders of any class of securities entitled to receive any such
Options or Convertible Securities, then the maximum number of shares (as set
forth in the instrument relating thereto without regard to any provisions
contained therein for a subsequent adjustment of such number) of Common Stock
issuable upon the exercise of such Options or, in the case of Convertible
Securities and Options therefor, the conversion or exchange of such Convertible
Securities, shall be deemed to be Additional Shares of Common Stock issued as of
the time of such issue or, in case such record date shall have been

                                       18
<PAGE>

fixed, as of the close of business on such record date, provided that Additional
Shares of Common Stock shall not be deemed to have been issued unless the
consideration per share (determined pursuant to Section 3(d)(v) hereof), of such
Additional Shares of Common Stock would be less than the Conversion Price in
effect on the date of and immediately prior to such issue, or such record date,
as the case may be, and provided further that in any such case in which
Additional Shares of Common Stock are deemed to be issued:

                         (A)  no further adjustment in the Conversion Price
shall be made upon the subsequent issue of Convertible Securities or shares of
Common Stock upon the exercise of such Options or conversion or exchange of such
Convertible Securities;

                         (B)  if such Options or Convertible Securities by their
terms provide, with the passage of time or otherwise, for any increase in the
consideration payable to the corporation, or decrease in the number of shares of
Common Stock issuable, upon the exercise, conversion or exchange thereof, the
Conversion Price computed upon the original issue thereof (or upon the
occurrence of a record date with respect thereto), and any subsequent
adjustments based thereon, shall, upon any such increase or decrease becoming
effective, be re-computed to reflect such increase or decrease insofar as it
affects such Options or the rights of conversion or exchange under such
Convertible Securities;

                         (C)  upon the expiration of any such Options or any
rights of conversion or exchange under such Convertible Securities which shall
not have been exercised, the Conversion Price computed upon the original issue
thereof (or upon the occurrence of a record date with respect thereto), and any
subsequent adjustments based thereon, shall, upon such expiration, be
re-computed as if:

                              (I)  in the case of Convertible Securities or
Options for Common Stock, the only Additional Shares of Common Stock issued were
the shares of Common Stock, if any, actually issued upon the exercise of such
Options or the conversion or exchange of such Convertible Securities and the
consideration received therefor was the consideration actually received by the
corporation for the issue of all such Options, whether or not exercised, plus
the consideration actually received by the corporation upon such exercise, or
for the issue of all such Convertible Securities which were actually converted
or exchanged, plus the additional consideration, if any, actually received by
the corporation upon such conversion or exchange, and

                              (II) in the case of Options for Convertible
Securities, only the Convertible Securities, if any, actually issued upon the
exercise thereof were issued at the time of issue of such Options, and the
consideration received by the corporation for the Additional Shares of Common
Stock deemed to have been then issued was the consideration actually received by
the corporation for the issue of all such Options, whether or not exercised,
plus the consideration deemed to have been received by the corporation
(determined pursuant to Section 3(d)(v) hereof) upon the issue of the
Convertible Securities with respect to which such Options were actually
exercised;

<PAGE>

                         (D)  no readjustment pursuant to clause (B) or (C)
above shall have the effect of increasing the Conversion Price to an amount
which exceeds the lower of (i) the Conversion Price on the original adjustment
data, or (ii) the Conversion Price that would have resulted from any issuance of
Additional Shares of Common Stock between the original adjustment date and such
readjustment date;

                         (E)  in the case of any Options which expire by their
terms not more than 30 days after the date of issue thereof, no adjustment of
the Conversion Price shall be made until the expiration or exercise of all such
Options, whereupon such adjustment shall be made in the same manner provided in
clause (C) above; and

                         (F)  if such record date shall have been fixed and such
Options or Convertible Securities are not issued on the date fixed therefor, the
adjustment previously made in the Conversion Price which became effective on
such record date shall be canceled as of the close of business on such record
date, and thereafter the Conversion Price shall be adjusted pursuant to this
subparagraph 3(d)(iii) as of the actual date of their issuance.

                    (2)  Stock Dividends, Stock Distributions and Subdivisions.
                         -----------------------------------------------------
In the event the corporation at any time or from time to time after the Original
Issue Date shall declare or pay any dividend or make any other distribution on
the Common Stock payable in Common Stock, or effect a subdivision of the
outstanding shares of Common Stock (by reclassification or otherwise than by
payment of a dividend in Common Stock), then and in any such event, Additional
Shares of Common Stock shall be deemed to have been issued:

                         (A)  in the case of any such dividend or distribution,
immediately after the close of business on the record date for the determination
of holders of any class of securities entitled to receive such dividend or
distribution, or

                         (B)  in the case of any such subdivision, at the close
of business on the date immediately prior to the date upon which such corporate
action becomes effective.

               If such record date shall have been fixed and such dividend shall
not have been fully paid on the date fixed therefor, the adjustment previously
made in the Conversion Price which became effective on such record date shall be
canceled as of the close of business on such record date, and thereafter the
Conversion Price shall be adjusted pursuant to this subparagraph 3(d)(iii) as of
the time of actual payment of such dividend.

               (iv) Adjustment of Conversion Price Upon Issuance of Additional
                    ----------------------------------------------------------
Shares of Common Stock. In the event the corporation shall issue Additional
- ----------------------
Shares of Common Stock (including Additional Shares of Common Stock deemed to be
issued pursuant to Section 3(d)(iii) hereof, but excluding Additional Shares of
Common Stock issued pursuant to Section 3(d)(iii)(2), which event is dealt with
in Section 3(d)(vi) hereof) without consideration or for a consideration per
share less than the Conversion Price in effect on the date of and immediately
prior to such issue, then and in such event, such Conversion Price shall be
reduced, concurrently

                                       20
<PAGE>

with such issue in order to increase the number of shares of Common Stock into
which the Class B Preferred is convertible, to a price (calculated to the
nearest cent) determined by multiplying such Conversion Price by a fraction (x)
the numerator of which shall be (1) the number of shares of Common Stock
outstanding immediately prior to such issue (including shares of Common Stock
issuable upon conversion of any outstanding Class A Preferred, Class B Preferred
or Convertible Securities), plus (2) the number of shares of Common Stock which
the aggregate consideration received by the corporation for the total number of
Additional Shares of Common Stock so issued would purchase at such Conversion
Price, and (y) the denominator of which shall be (1) the number of shares of
Common Stock outstanding immediately prior to such issue (including shares of
Common Stock issuable upon conversion of any outstanding Class A Preferred,
Class B Preferred or Convertible Securities), plus (2) the number of such
Additional Shares of Common Stock so issued, provided that the Conversion Price
shall not be so reduced at such time if the amount of such reduction would be an
amount less than $0.05, but any such amount shall be carried forward and
reduction with respect thereto made at the time of and together with any
subsequent reduction which, together with such amount and any other amount or
amounts so carried forward, shall aggregate $0.05 or more.

               (v)  Determination of Consideration. For purposes of this Section
                    ------------------------------
3(d), the consideration received by the corporation for the issue of any
Additional Shares of Common Stock shall be computed as follows:

                    (1)  Cash and Property.  Such consideration shall:
                         -----------------

                         (A)  insofar as it consists of cash, be computed at the
aggregate amount of cash received by the corporation excluding amounts paid or
payable for accrued interest or accrued dividends;

                         (B)  insofar as it consists of property other than
cash, be computed at the fair value thereof at the time of such issue, as
determined in good faith by the Board of Directors; and

                         (C)  in the event Additional Shares of Common Stock are
issued together with other shares or securities or other assets of the
corporation for consideration which covers both, be the proportion of such
consideration so received, computed as provided in clauses (A) and (B) above, as
determined in good faith by the Board of Directors.

                    (2)  Options and Convertible Securities. The consideration
                         ----------------------------------
per share received by the corporation for Additional Shares of Common Stock
deemed to have been issued pursuant to Section 3(d)(iii)(1) above, relating to
Options and Convertible Securities shall be determined by dividing

                         (x)  the total amount, if any, received or receivable
by the corporation as consideration for the issue of such Options or Convertible
Securities, plus the minimum aggregate amount of additional consideration (as
set forth in the instruments relating thereto, without regard to any provision
contained therein for a subsequent adjustment of such

                                       21
<PAGE>

consideration until such subsequent adjustment occurs) payable to the
corporation upon the exercise of such Options or the conversion or exchange of
such Convertible Securities, or in the case of Options for Convertible
Securities, the exercise of such Options for Convertible Securities and the
conversion or exchange of such Convertible Securities, by

                         (y)  the maximum number of shares of Common Stock (as
set forth in the instruments relating thereto, without regard to any provision
contained therein for a subsequent adjustment of such number until such
subsequent adjustment occurs) issuable upon the exercise of such Options or the
conversion or exchange of such Convertible Securities.

               (vi)  Adjustment for Dividends, Distributions, Subdivisions,
                     -----------------------------------------------------
Combinations or Consolidation of Common Stock.
- ---------------------------------------------

                     (1) Stock Dividends, Distributions or Subdivisions. In the
                         ----------------------------------------------
event the corporation shall issue Additional Shares of Common Stock pursuant to
Section 3(d)(iii)(2) hereof in a stock dividend, stock distribution or
subdivision, the Conversion Price in effect immediately prior to such stock
dividend, stock distribution or subdivision shall, concurrently with the
effectiveness of such stock dividend, stock distribution or subdivision, be
proportionately decreased.

                     (2) Combination or Consolidations. In the event the
                         -----------------------------
outstanding shares of Common Stock shall be combined or consolidated, by
reclassification or otherwise, into a lesser number of shares of Common Stock,
the Conversion Price in effect immediately prior to such combination or
consolidation shall, concurrently with the effectiveness of such combination or
consolidation, be proportionately increased.

               (vii) Adjustment for Merger or Reorganization.  In case of any
                     ---------------------------------------
consolidation or merger of the corporation with or into another corporation or
the conveyance of all or substantially all of the assets of the corporation to
another corporation, each share of Class B Preferred 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 Class B Preferred would have been entitled
upon such consolidation, merger or conveyance; and, in any such case,
appropriate adjustment (as determined by the Board of Directors) shall be made
in the application of the provisions herein set forth with respect to the rights
and interest thereafter of the holders of the Class B Preferred, to the end that
the provisions set forth herein (including provisions with respect to changes in
and other adjustments of the Conversion Price) shall thereafter be applicable,
as nearly as reasonably may be, in relation to any shares of stock or other
property thereafter deliverable upon the conversion of the Class B Preferred.

     Each holder of Class B Preferred upon the occurrence of a capital
reorganization, merger or consolidation of the corporation or the sale of all or
substantially all its assets and properties as such events are more fully set
forth in the first paragraph of this Section 3(d)(vii),

                                       22
<PAGE>

or Section 2 hereof, notice of which election shall be submitted in writing to
the corporation at its principal offices no later than five (5) days before the
effective date of such event.

          (e)  No Impairment. The corporation will not, by amendment of its
               -------------
Restated Articles of Organization or through any reorganization, 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 the 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
Class B Preferred against impairment.

          (f)  Certificate as to Adjustments. Upon the occurrence of each
               -----------------------------
adjustment or readjustment of the Conversion Price pursuant to this Section 3,
the corporation at its expense shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and furnish to each holder of
Class B Preferred a certificate setting forth such adjustment or readjustment
and showing in detail the facts upon which such adjustment or readjustment is
based. The corporation shall, upon the written request at any time of any holder
of Class B Preferred, furnish or cause to be furnished to such holder a like
certificate setting forth (i) such adjustments and readjustments, (ii) the
Conversion Price at the time in effect, and (iii) the number of shares of Common
Stock and the amount, if any, of other property which at the time would be
received upon the conversion of Class B Preferred.

          (g)  Notice of Record Date.  In the event of (i) any taking by the
               ---------------------
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 which is the same as cash dividends paid in
previous quarters) or other distribution, or (ii) any capital reorganization of
the corporation, any reclassification or recapitalization of the capital stock
of the corporation, any merger or consolidation of the corporation, and any
transfer of all or substantially all of the assets of the corporation to any
other corporation, or any other entity or person, or any voluntary or
involuntary dissolution, liquidation or winding up of the corporation, the
corporation shall mail to each holder of Class B Preferred at least 20 days
prior to the record date specified therein, a notice specifying (A) the date on
which any such record is to be taken for the purpose of such dividend or
distribution and a description of such dividend or distribution, (B) the date on
which any such reorganization, reclassification, transfer, consolidation,
merger, dissolution, liquidation or winding up is expected to become effective,
and (C) the time, if any, that is to be fixed, as to when the holders of record
of Common Stock (or other securities) shall be entitled to exchange their shares
of Common Stock (or other securities) for securities or other property
deliverable upon such reorganization, reclassification, transfer, consolidation,
merger, dissolution, liquidation or winding up.

          (h)  Common Stock Reserved.  The corporation shall reserve and keep
               ---------------------
available out of its authorized but unissued Common Stock such number of shares
of Common Stock as shall from time to time be sufficient to effect conversion of
the Class B Preferred.

                                       23
<PAGE>

     Section 4.  Redemption.  (a) There shall be a five-year period (the
     ---------   ----------
"Redemption Period") for each share of the Class B Preferred commencing five
years after the date of issuance for any Class B Preferred or on March 28, 1999,
whichever is later.  On the commencement date of the Redemption Period for each
share of the Class B Preferred eligible for redemption and on the first, second,
third and fourth anniversaries thereof, the corporation shall offer to each
holder of shares of Class B Preferred eligible for redemption to redeem a
maximum of twenty percent (20%), forty percent (40%), sixty percent (60%),
eighty percent (80%) and one hundred percent (100%), respectively, of the total
number of shares of Class B Preferred held by such holder prior to the
commencement of the Redemption Period with respect to such Class B Preferred, at
a price of three dollars and twenty-five cents ($3.25) per share, plus an amount
equal to all declared but unpaid dividends payable in accordance with Section 6
hereof on each share of Class B Preferred tendered for redemption; provided,
that any shares of Class B Preferred redeemed hereunder in any previous years
shall reduce the maximum amount of Class B Preferred which the corporation may
be requested to redeem in any then current year. The corporation shall offer to
redeem shares of Class B Preferred eligible for redemption by giving written
notice thereof to each holder of shares of Class B Preferred eligible for
redemption, which notice shall state the number of shares of Class B Preferred
eligible to be redeemed by such holder and shall specify a redemption date not
less than forty-five (45) days nor more than sixty (60) days after the date of
such written notice.  Any holder of shares of Class B Preferred eligible to be
redeemed may redeem such shares by giving written notice thereof to the
corporation, and to each other holder of shares of Class B Preferred, no less
than 15 days prior to the redemption date specified in the corporation's written
offer of redemption, and by surrendering to the corporation on or before the
redemption date the share certificates for the number of shares of Class B
Preferred to be redeemed.  If less than all of the shares represented by such
certificates are redeemed, a new certificate shall be issued for the unredeemed
shares as promptly as possible.  Notwithstanding the foregoing, the holders of
sixty-six and two-thirds percent (66 2/3%) or more of the Class B Preferred
shall have the right to postpone for a specified period of time or waive such
rights of redemption of all holders by written notice to the corporation and to
all such holders given at least fifteen (15) days prior to the scheduled date of
redemption.

          (b)  In the event of a sale of all or substantially all the assets of
the corporation, then the corporation shall offer to each holder of shares of
Class B Preferred to redeem not less than all the shares of Class B Preferred
held by such holder on the date the corporation fixes as the date to mail or
otherwise send out its offer of redemption, at a redemption price of three
dollars and twenty-five cents ($3.25) per share plus an amount equal to all
declared but unpaid dividends payable in accordance with Section 6 hereof on
each such share of Class B Preferred tendered for redemption. The corporation
shall offer to redeem shares of Class B Preferred by giving written notice
thereof to each holder of shares of Class B Preferred, which notice shall be
sent not less than twenty (20) days before the scheduled date of consummation of
the transaction described above. Such notice of redemption shall state the
number of shares of Class B Preferred eligible to be redeemed by such holder and
shall specify a redemption date not less than twenty (20) days nor more than
sixty (60) days after the date of such written notice. Any holder of shares of
Class B Preferred may redeem such shares by giving written notice thereof to the
corporation not less than ten (10) days prior to the redemption date specified
in the corporation's

                                       24
<PAGE>

written offer of redemption, and by surrendering to the corporation on or before
the redemption date the share certificates for the number of shares of Class B
Preferred to be redeemed.

     Section 5.  Voting Rights.
     ---------   -------------

          (a)  The holders of shares of Class B Preferred shall be entitled to
notice of any shareholders' meeting and to vote upon any matter submitted to a
shareholder for a vote, as though the Common Stock, the Class A Preferred, the
Class B Preferred and the Class C Preferred constitute a single class of stock,
except with respect to those matters on which the Massachusetts Corporation Law
requires that a vote must be by a separate class or classes or by separate
series. For all votes other than votes by a separate class or series, holders of
Class B Preferred shall have that number of votes per share as is equal to the
number of shares of Common Stock into which each such share of Class B Preferred
held by such holder is then convertible, provided, however, that at any time, if
the number of shares of Common Stock into which the Class B Preferred is
convertible is increased as a result of an adjustment of the Conversion Price,
all as set forth in Section 3 above, the holders of Class B Preferred shall have
that number of votes equal to the number of shares of Common Stock into which
such Class B Preferred is convertible.

          (b)  The holders of Class A Preferred, the holders of Class B
Preferred, the holders of Class C Preferred and the holders of Common Stock
shall be entitled to vote upon the election of directors on the following basis:
So long as at least 50,000 shares of Class A Preferred and Class B Preferred,
collectively, shall be outstanding, the holders of Class A Preferred and Class B
Preferred issued and outstanding, voting as a single class, are entitled to
elect three directors; and the holders of Class A Preferred, Class B Preferred,
Class C Preferred and Common Stock and any other capital stock having voting
rights are entitled to elect all other members of the Board of Directors.

     Section 6.  Dividend Rights.
     ---------   ---------------

          (a)  The holders of the then outstanding shares of Class B Preferred
shall be entitled to receive, when and as declared by the Board Directors, out
of funds legally available therefor, non-cumulative cash dividends at the annual
rate of $.26 per share payable at a rate of $.065 per share per calendar
quarter. The corporation's obligation to pay such dividends shall commence after
the first calendar quarter when the corporation's net after tax income,
calculated in accordance with generally accepted accounting principles, exceeds
five times such quarterly dividend on all then outstanding Class A Preferred,
Class B Preferred and Class C Preferred and on all then outstanding shares of
any other class of preferred stock of the corporation.

          (b)  Notwithstanding any provisions in Section 6(a) hereof, dividends
which have been declared on the Class B Preferred but not been paid prior to an
automatic conversion pursuant to Section 3(b) hereof shall be payable within 30
days of the conversion, as defined in Section 3(b), to each person who holds of
record Class B Preferred immediately prior to the automatic conversion.

                                       25
<PAGE>

     Section 7.  Covenants.  So long as at least 50,000 shares of Class A
     ---------   ---------
Preferred and Class B Preferred, collectively, shall be outstanding (as adjusted
for all subdivisions and combinations), the corporation shall not, without first
obtaining the affirmative vote or written consent of not less than sixty-six
percent (66%) of such outstanding shares of Class A Preferred and Class B
Preferred, collectively:

          (a)  amend or repeal any provision of, or add any provision to, the
corporation's Restated Articles of Organization or By-Laws if such action would
alter or change the preferences, rights, privileges or powers of, or the
restrictions provided for the benefit of, the Class A Preferred and/or Class B
Preferred generally except with respect to any class or any series of preferred
stock of the corporation created by the Board of Directors pursuant to a
Certificate of Designation in accordance with the provisions of these Revised
Articles of Organization so long as the shares of the class or series created do
not have any preference or priority as to dividends or assets superior to the
Class A Preferred and/or Class B Preferred;

          (b)  reclassify any Common Stock into shares having any preference or
priority as to dividends or assets superior to or on a parity with any such
preference or priority of the Class A Preferred and/or Class B Preferred;

          (c)  pay or declare any dividend or distribution on any shares of
Common Stock or apply any of its assets to the redemption, retirement, purchase
or other acquisition directly or indirectly, through subsidiaries, if any, or
otherwise, of any shares of Common Stock except from officers, directors or
employees of or consultants to the corporation upon termination of employment
and except pursuant to the corporation's rights of first refusal; or

          (d)  create any other class or classes of stock or series of preferred
stock having any preference or priority as to dividends or assets superior to
any such preference or priority of the Class A Preferred and/or Class B
Preferred; or

          (e)  authorize any merger or consolidation of the corporation with or
into any other corporation or entity (except into or with a wholly-owned
subsidiary corporation with the requisite shareholder approval), or authorize
the sale of substantially all of the assets of the corporation.

                            CLASS C PREFERRED STOCK
                            -----------------------

     Section 1.  Designation.  No (0) shares of Preferred Stock are hereby
     ---------   -----------
designated as "Class C Preferred Stock" (the "Class C Preferred Stock").

     Section 2.  Liquidation Rights.  In the event of any voluntary or
     ---------   ------------------
involuntary liquidation, dissolution or winding up of the affairs of the
corporation, the holders of each share of Class C Preferred shall be entitled to
receive, prior and in preference to any distribution of any of the assets or
surplus funds of the corporation to the holders of the Common Stock of the
corporation by reason of their ownership thereof, but after any distributions
upon any voluntary or involuntary liquidation, dissolution or winding up of the
affairs of the corporation to holders of

                                       26
<PAGE>

the Class A Preferred and Class B Preferred as provided in these Restated
Articles of Organization, an amount equal to twelve dollars and fifty cents
($12.50) per share plus an amount equal to all declared but unpaid dividends to
and including the date full payment shall be tendered to the holder of the Class
C Preferred with respect to such liquidation, dissolution or winding up.

     All of the preferential amounts to be paid to the holders of the Class C
Preferred under this Section 2 shall be paid or set apart for payment before the
payment or setting apart for payment of any amount for, or the distribution of
any assets of the corporation to, the holders of the Common Stock in connection
with such liquidation, dissolution or winding up.  After the payment or the
setting apart of payment to the holders of the Class C Preferred of the
preferential amounts so payable to them, the holders of the Common Stock shall
be entitled to receive all remaining assets of the corporation.

     If the assets or surplus funds to be distributed to the holders of the
Class C Preferred are insufficient to permit the payment to such holders of
their full preferential amount, the assets and surplus funds legally available
for distribution shall be distributed ratably among the holders of the Class C
Preferred in proportion to the full preferential amount each such holder is
otherwise entitled to receive.

     A consolidation or merger of the corporation or a sale of all or
substantially all of the assets of the corporation shall be regarded as a
liquidation, dissolution or winding up of the affairs of the corporation within
the meaning of this Section 2.

     Section 3.  Conversion. The holders of the Class C Preferred shall have
     ---------   ----------
conversion rights as follows (the "Conversion Rights"):

          (a)  Right to Convert.  Each share of Class C Preferred shall be
               ----------------
convertible, without the payment of any additional consideration by the holder
thereof and at the option of the holder thereof, at any time after the date of
issuance of such share, at the office of the corporation or any transfer agent
for the Class C Preferred, into one (1) fully paid and nonassessable share of
Common Stock.

          (b)  Automatic Conversion.  Each share of Class C Preferred shall
               --------------------
automatically be converted into one share of Common Stock upon the closing of a
firm commitment underwritten public offering pursuant to an effective
registration statement under the Securities Act of 1933, as amended, covering
the offer and sale of Common Stock for the account of the corporation to the
public at a public offering price of at least $9.75 per share and having an
aggregate offering price to the public resulting in gross proceeds to the
corporation of not less than $15,000,000 (in the event of which offering, the
person(s) entitled to receive the Common Stock issuable upon such conversion of
the Class C Preferred shall not be deemed to have converted that Class C
Preferred until immediately prior to the closing of such offering).  Each person
who holds of record Class C Preferred immediately prior to such automatic
conversion shall be entitled to all dividends which have accrued to the time of
the automatic

                                       27
<PAGE>

conversion, but not paid on the Class C Preferred, pursuant to Section 6 hereof.
Such dividends shall be paid to all such holders within 30 days of the automatic
conversion.

          (c)  Mechanics of Conversion. Before any holder of Class C Preferred
               -----------------------
shall be entitled to convert the same into shares of Common Stock, he shall
surrender the certificate or certificates therefor, duly endorsed, at the office
of the corporation or of any transfer agent for the Class C Preferred, and shall
give written notice to the corporation at such office that he elects to convert
the same and shall state therein his name or the name or names of his nominees
in which he wishes the certificate or certificates for shares of Common Stock to
be issued. The corporation shall, as soon as practicable thereafter, issue and
deliver at such office to such holder of Class C Preferred, or to his nominee or
nominees, a certificate or certificates for the number of shares of Common Stock
to which he 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 Class C Preferred to be converted, and the person or
persons entitled to receive the shares of Common Stock issuable upon conversion
shall be treated for all purposes as the record holder or holders of such shares
of Common Stock on such date.

          (d)  No Impairment. The corporation will not, by amendment of its
               -------------
Restated Articles of Organization or through any reorganization, 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 the 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
Class C Preferred against impairment.

          (e)  Notice of Record Date.  In the event of (i) any taking by the
               ---------------------
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 which is the same as cash dividends paid in
previous quarters) or other distribution, or (ii) any capital reorganization of
the corporation, any reclassification or recapitalization of the capital stock
of the corporation, any merger or consolidation of the corporation, and any
transfer of all or substantially all of the assets of the corporation to any
other corporation, or any other entity or person, or any voluntary or
involuntary dissolution, liquidation or winding up of the corporation, the
corporation shall mail to each holder of Class C Preferred at least 20 days
prior to the record date specified therein, a notice specifying (A) the date on
which any such record is to be taken for the purpose of such dividend or
distribution and a description of such dividend or distribution, (B) the date on
which any such reorganization, reclassification, transfer, consolidation,
merger, dissolution, liquidation or winding up is expected to become effective,
and (C) the time, if any, that is to be fixed, as to when the holders of record
of Common Stock (or other securities) shall be entitled to exchange their shares
of Common Stock (or other securities) for securities or other property

               ---------------------
available out of its authorized but unissued Common Stock such number of shares
of Common Stock as shall from time to time be sufficient to effect conversion of
the Class C Preferred.

     Section 4.  Redemption.  The Class C Preferred shall be redeemable only
     ---------   ----------
upon the mutual agreement of the holders thereof and the corporation.  The
corporation shall have no obligation to redeem any shares of the Class C
Preferred.

     Section 5.  Voting Rights.
     ---------   -------------

          (a)  The holders of shares of Class C Preferred shall be entitled to
notice of any shareholders' meeting and to vote upon any matter submitted to a
shareholder for a vote, as though the Common Stock, the Class A Preferred, the
Class B Preferred and the Class C Preferred constitute a single class of stock,
except with respect to those matters on which the Massachusetts Corporation Law
requires that a vote must be by a separate class or classes or by separate
series. For all votes, holders of Class C Preferred shall have one vote per
share.

          (b)  The holders of Class A Preferred, the holders of the Class B
Preferred, the holders of Class C Preferred and the holders of Common Stock
shall be entitled to vote upon the election of directors on the following basis:
So long as at least 50,000 shares of Class A Preferred and Class B Preferred,

Class C Preferred shall be entitled to receive, when and as declared by the
Board Directors, out of funds legally available therefor, non-cumulative cash
dividends at the annual rate of $1.00 per share payable at a rate of $.25 per

tax income, calculated in accordance with generally accepted accounting
principles, exceeds five times such quarterly dividend on all then outstanding
Class A Preferred, Class B Preferred and Class C Preferred and on all then
outstanding shares of any other class of preferred stock of the corporation.

     Section 2.  Liquidation Rights.
     ----------  ------------------

          (a) Payment to Holders of Class D Preferred Stock Upon Liquidation.
              --------------------------------------------------------------
In the event of any voluntary or involuntary liquidation, dissolution or
winding-up of the affairs of the corporation, the holder of each share of Class
D Preferred shall be entitled to receive, prior and in preference to any
distribution of any of the assets or surplus funds of the corporation to the
holders of the Class A Preferred, the Class C Preferred and the Common Stock of
the corporation by reason of their ownership thereof, an amount equal to (i)
$1.80 per share of Class D Preferred plus (ii) an amount equal to all declared
but unpaid dividends to and including the date full payment shall be tendered to
the holder of the Class D Preferred with respect to such liquidation,
dissolution or winding-up.

All of the preferential amounts to be paid to the holders of the Class D
Preferred under this Section 2(a) shall be paid or set apart for payment before
the payment or setting apart for payment of any amount for, or the distribution
of any assets of the corporation to, the holders of the Class A Preferred, Class
C Preferred and Common Stock in connection with such liquidation, dissolution or
winding-up.  If the assets or surplus funds to be distributed to the holders of
the Class B Preferred and the Class D Preferred are insufficient to permit the
payment to such holders of their full preferential amount, the assets and
surplus funds legally available for distribution shall be distributed ratably
among the holders of Class D Preferred and Class B Preferred in proportion to
the full preferential amount each such holder is otherwise entitled to receive.

          (b) Payment to Holders of Class D Preferred and Common Stock.  After
              --------------------------------------------------------
the payment or the setting apart of payment to the holders of the Class A
Preferred, the Class B Preferred, the Class C Preferred and the Class D
Preferred of the preferential amounts so payable to them, all remaining assets
of the corporation shall be distributed among the holders of the Class D
Preferred and the holders of the Common Stock ratably in proportion to the
number of shares of Class D Preferred and Common Stock (and, in the case of
Class D Preferred, the number of shares of Common Stock into which each such
share of Class D Preferred held by such holder could be converted on the record
date for the determination of rights of stockholders to distributions under this
Section 2) held by them.

          (c) No Liquidation Preference After Conversion.  Upon conversion of
              ------------------------------------------
shares of Class D Preferred into shares of Common Stock pursuant to Section 3
below, the holder of such Common Stock shall not be entitled to any preferential
payment or distribution in case of any liquidation, dissolution or winding-up of
corporation, but shall share ratably in any distribution of the assets of the
corporation to all holders of Common Stock.

          (d) Distributions Other than Cash.  Whenever the distribution provided
              -----------------------------
for in this Section 2 shall be payable in property other than cash, the value of
such distribution shall be the fair market value of such property as determined
in good faith by the Board of Directors of the corporation.

          (e) Merger as Liquidation, etc.  The merger or consolidation of the
              --------------------------
corporation into or with another corporation (other than a wholly-owned
subsidiary of this corporation in a merger in which this corporation is the
surviving corporation and its Articles of Organization remain unchanged), or the
sale of all or substantially all of the assets of the corporation (other than to
a wholly-owned subsidiary of this corporation) shall be deemed to be a
liquidation, dissolution or winding-up of the corporation for purposes of this
Section 2 unless the holders of at least 51% of the then outstanding shares of
Class D Preferred (voting as a single class) 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(f) shall apply.  The amount deemed distributed to the holders of Class
D Preferred upon any such merger or consolidation shall be the cash or the value
of the property, rights or securities distributed to such holders by the
acquiring person, firm or other entity.  The value of such property, rights or
other securities shall be determined in good faith by the Board of Directors of
the corporation.

          (f) Notice and Opportunity to Exercise Conversion Rights.
              ----------------------------------------------------
Notwithstanding anything to the contrary that may be inferred from the
provisions of this Section 2, each holder of shares of Class D Preferred shall
be entitled to receive notice from the corporation pursuant to Section 3(i)
hereof of any proposed liquidation, dissolution or winding-up of the corporation
at least 20 days prior to the date on which any such liquidation, dissolution or
winding-up of the corporation is scheduled to occur and, at any time prior to
any such liquidation, dissolution or winding-up of the corporation, to convert
any or all of such holder's shares of Class D Preferred into shares of Common
Stock pursuant to Section 3 hereof.

     Section 3.  Conversion.  The holders of the Class D Preferred shall have
     ----------  ----------
conversion rights as follows (the "Conversion Rights"):

          (a) Right to Convert.  Each share of Class D Preferred shall be
              -----------------
convertible, without the payment of any additional consideration by the holder
thereof and at the option of the holder thereof, at any time after the date of
issuance of such share, at the office of the corporation or any transfer agent
for the Class D Preferred, into such fully paid and nonassessable shares of
Common Stock, as is determined by dividing one dollar and eighty cents ($1.80)
by the Conversion Price, determined as hereinafter provided, in effect at the
time of conversion. The Conversion Price at which shares of Common Stock shall
be deliverable upon conversion without the payment of any additional
consideration by the holder thereof (the "Conversion Price") shall initially be
one dollar and eighty cents ($1.80) per share of Common Stock. Such initial
Conversion Price shall be subject to adjustment, in order to adjust the number
of shares of Common Stock into which the Class D Preferred is convertible, as
hereinafter provided.

          (b) Automatic Conversion.
              --------------------

                    (i)  Upon Qualifying Public Offerings. Each share of Class D
                         --------------------------------
Preferred shall automatically be converted into shares of Common Stock at the
then effective Conversion Price upon the closing of a firm commitment
underwritten public offering pursuant to an effective registration statement
under the Securities Act of 1933, as amended, covering the offer and sale of
Common Stock for the account of the corporation to the public at a public

                                       31
<PAGE>

offering price of at least $4.50 per share (with such amount to be appropriately
adjusted in the event of any stock dividend, stock distribution or subdivision
as provided in subparagraph (e) hereof and having an aggregate offering price to
the public resulting in gross proceeds to the corporation of not less than
$15,000,000 (in the event of which offering, the person(s) entitled to receive
the Common Stock issuable upon such conversion of the Class D Preferred shall
not be deemed to have converted that Class D Preferred until immediately prior
to the closing of such offering). Each person who holds of record Class D
Preferred immediately prior to such automatic conversion shall be entitled to
all dividends which have accrued to the time of the automatic conversion, but
have not been paid on the Class D Preferred, pursuant to Section 6 hereof. Such
dividends shall be paid to all such holders within 30 days of the automatic
conversion.

                    (ii) Upon Conversion of 90% of Class D Preferred. Each share
                         -------------------------------------------
of Class D Preferred then outstanding shall automatically be converted into
shares of Common Stock at the then effective Conversion Price, upon the
conversion of ninety percent (90%) or more of the authorized Class D Preferred.
Such conversion shall be deemed to have occurred on the date upon which the
aggregate number of shares of Class D Preferred which have been converted to
Common Stock equals or exceeds ninety percent (90%) of the authorized Class D
Preferred.

          (c)  Mechanics of Conversion.  No fractional shares of Common Stock
               -----------------------
shall be issued upon conversion of the Class D Preferred.  In lieu of any
fractional shares to which the holder would otherwise be entitled, the
corporation shall pay cash equal to such fraction multiplied by the then
effective Conversion Price. Before any holder of Class D Preferred shall be
entitled to convert the same into full shares of Common Stock, he shall
surrender the certificate or certificates therefor, duly endorsed, at the office
of the corporation or of any transfer agent for the Class D Preferred, and shall
give written notice to the corporation at such office that he elects to convert
the same and shall state therein his name or the name or names of his nominees
in which he wishes the certificate or certificates for shares of Common Stock to
be issued. The corporation shall, as soon as practicable thereafter, issue and
deliver at such office to such holder of Class D Preferred, or to his nominee or
nominees, a certificate or certificates for the number of shares of Common Stock
to which he shall be entitled as aforesaid, together with cash in lieu of any
fraction of a share. 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 Class D Preferred to be converted, and the person or persons entitled
to receive the shares of Common Stock issuable upon conversion shall be treated
for all purposes as the record holder or holders of such shares of Common Stock
on such date.

          (d)  Adjustments to Conversion Price for Diluting Issues.
               ---------------------------------------------------

                    (i)  Special Definitions. For purposes of this Section 3(d),

shares of Common Stock issued (or, pursuant to Section 3(d)(iii) hereof, deemed
to be issued) by the corporation after the Original Issue Date, other than:

                              (A)  shares of Common Stock issued or issuable

                              (C)  shares of Common Stock issued by way of
dividend or other distribution on shares of Common Stock excluded from the
definition of Additional Shares of Common Stock by the foregoing clauses (A) and

the number of shares of Common Stock into which the Class D Preferred is
convertible shall be made, by adjustment in the Conversion Price of Class D
Preferred in respect of the issuance of Additional Shares of Common Stock or
otherwise, unless the consideration per share for an Additional Share of Common
Stock issued or deemed to be issued by the corporation is less than the
Conversion Price in effect on the date of, and immediately prior to, the issue
of such Additional Share.

of Common Stock.
- ---------------

                          (1) Options and Convertible Securities. In the event
                              ----------------------------------
the corporation at any time or from time to time after the Original Issue Date
shall issue any Options or Convertible Securities or shall fix a record date for
the determination of holders of any class of securities entitled to receive any
such Options or Convertible Securities, then the maximum number of shares (as
set forth in the instrument relating thereto without regard to any provisions
contained therein for a subsequent adjustment of such number) of Common Stock
issuable upon the exercise of such Options or, in the case of Convertible
Securities and Options therefor, the conversion or exchange of such Convertible
Securities, shall be deemed to be Additional Shares of Common Stock issued as of
the time of such issue or, in case such record date shall have been fixed, as of
the close of business on such record date, provided that Additional Shares of
Common Stock shall not be deemed to have been issued unless the consideration
per share (determined pursuant to Section 3(d)(v) hereof), of such Additional
Shares of Common Stock would be less than the Conversion Price in effect on the
date of and immediately prior to such issue, or such record date, as the case
may be, and provided further that in any such case in which Additional Shares of
Common Stock are deemed to be issued:

                              (A)  no further adjustment in the Conversion Price
shall be made upon the subsequent issue of Convertible Securities or shares of
Common Stock upon the exercise of such Options or conversion or exchange of such
Convertible Securities;

                              (B)  if such Options or Convertible Securities by
their terms provide, with the passage or time or otherwise, for any increase in
the consideration payable to the corporation, or decrease in the number of
shares of Common Stock issuable, upon the exercise, conversion or exchange
thereof, the Conversion Price computed upon the original issue thereof (or upon
the occurrence of a record date with respect thereto), and any subsequent
adjustments based thereon, shall, upon any such increase or decrease becoming
effective, be recomputed to reflect such increase or decrease insofar as it
affects such Options or the rights of conversion or exchange under such
Convertible Securities;

                              (C)  upon the expiration of any such Options or
any rights of conversion or exchange under such Convertible Securities which
shall not have been exercised, the Conversion Price computed upon the original
issue thereof (or upon the occurrence of a record date with respect thereto),
and any subsequent adjustments based thereon, shall, upon such expiration, be
recomputed as if:

                                   (I)  in the case of Convertible Securities or
Options for Common Stock, the only Additional Shares of Common Stock issued were
the shares of Common Stock, if any, actually issued upon the exercise of such
Options or the conversion or exchange of such Convertible Securities and the
consideration received therefor was the consideration actually received by the
corporation for the issue of all such Options, whether or not exercised, plus
the consideration actually received by the corporation upon such exercise, or
for the issue of all such Convertible Securities which were actually converted
or

                                       34
<PAGE>

exchanged, plus the additional consideration, if any, actually received by the
corporation upon such conversion or exchange, and

                                   (II) in the case of Options for Convertible
Securities, only the Convertible Securities, if any, actually issued upon the
exercise thereof were issued at the time of issue of such Options, and the
consideration received by the corporation for the Additional Shares of Common
Stock deemed to have been then issued was the consideration actually received by
the corporation for the issue of all such Options, whether or not exercised,
plus the consideration deemed to have been received by the corporation
(determined pursuant to Section 3(d)(v) hereof) upon the issue of the
Convertible Securities with respect to which such Options were actually
exercised;

                              (D)  no readjustment pursuant to clause (B) or (C)
above shall have the effect of increasing the Conversion Price to an amount
which exceeds the lower of (i) the Conversion Price on the original adjustment
date, or (ii) the Conversion Price that would have resulted from any issuance of
Additional Shares of Common Stock between the original adjustment date and such
readjustment date;

                              (E)  in the case of any Options which expire by
their terms not more than 30 days after the date of issue thereof, no adjustment
of the Conversion Price shall be made until the expiration or exercise of all
such Options, whereupon such adjustment shall be made in the same manner
provided in clause (C) above; and

                              (F)  if such record date shall have been fixed and
such Options or Convertible Securities are not issued on the date fixed
therefor, the adjustment previously made in the Conversion Price which became
effective on such record date shall be canceled as of the close of business on
such record date and thereafter the Conversion Price shall be adjusted pursuant
to this subparagraph 3(d)(iii) as of the actual date of their issuance.

                         (2)  Stock Dividends, Stock Distributions and
                              ----------------------------------------
Subdivisions. In the event the corporation at any time or from time to time
- ------------
after the Original Issue Date shall declare or pay any dividend or make any
other distribution on the Common Stock payable in Common Stock, or effect a
subdivision of the outstanding shares of Common Stock (by reclassification or
otherwise than by payment of a dividend in Common Stock), then and in any such
event, Additional Shares of Common Stock shall be deemed to have been issued:

                              (A)  in the case of any such dividend or
distribution, immediately after the close of business on the record date for the
determination of holders of any class of securities entitled to receive such
dividend or distribution, or

                              (B)  in the case of any such subdivision, at the
close of business on the date immediately prior to the date upon which such
corporate action becomes effective.

                                       35
<PAGE>

     If such record date shall have been fixed and such dividend shall not have
been fully paid on the date fixed therefor, the adjustment previously made in
the Conversion Price which became effective on such record date shall be
canceled as of the close of business on such record date, and thereafter the
Conversion Price shall be adjusted pursuant to this subparagraph 3(d)(iii) as of
the time of actual payment of such dividend.

                    (iv)  Adjustment of Conversion Price Upon Issuance of
                          -----------------------------------------------
Additional Shares of Common Stock. In the event the corporation shall issue
- ---------------------------------
Additional Shares of Common Stock (including Additional Shares of Common Stock
deemed to be issued pursuant to Section 3(d)(iii) hereof, but excluding
Additional Shares of Common Stock issued pursuant to Section 3(d)(iii)(2), which
event is dealt with in Section 3(e) hereof) without consideration or for a
consideration per share less than the Conversion Price in effect on the date of
and immediately prior to such issue, then and in such event, such Conversion
Price shall be reduced, concurrently with such issue in order to increase the
number of shares of Common Stock into which the Class D Preferred is
convertible, to a price (calculated to the nearest cent) determined by
multiplying such Conversion Price by a fraction (x) the numerator of which shall
be (1) the number of shares of Common Stock outstanding immediately prior to
such issue (including shares of Common Stock issuable upon conversion of any
outstanding Class A Preferred, Class B Preferred, Class C Preferred, Class D
Preferred or Convertible Securities) plus (2) the number of shares of Common
Stock which the aggregate consideration received by the corporation for the
total number of Additional Shares of Common Stock so issued would purchase at
such Conversion Price, and (y) the denominator of which shall be (1) the number
of shares of Common Stock outstanding immediately prior to such issue (including
shares of Common Stock issuable upon conversion of any outstanding Class A
Preferred, Class B Preferred, Class C Preferred, Class D Preferred or
Convertible Securities), plus (2) the number of such Additional Shares of Common
Stock so issued, provided that the Conversion Price shall not be so reduced at
such time if the amount of such reduction would be an amount less than $0.05,
but any such amount shall be carried forward and reduction with respect thereto
made at the time of and together with any subsequent reduction which, together
with such amount and any other amount or amounts so carried forward, shall
aggregate $0.05 or more.

                    (v)   Determination of Consideration. For purposes of this
                          ------------------------------
Section 3(d), the consideration received by the corporation for the issue of any
Additional Shares of Common Stock shall be computed as follows:

                          (1) Cash and Property.  Such consideration shall:
                              -----------------

                              (A)  insofar as it consists of cash, be computed
at the aggregate amount of cash received by the corporation excluding amounts
paid or payable for accrued interest or accrued dividends;

                              (B)  insofar as it consists of property other than
cash, be computed at the fair value thereof at the time of such issue, as
determined in good faith by the Board of Directors; and

                                       36
<PAGE>

                              (C)  in the event Additional Shares of Common
Stock are issued together with other shares or securities or other assets of the
corporation for consideration which covers both, be the proportion of such
consideration so received, computed as provided in clauses (A) and (B) above, as
determined in good faith by the Board of Directors.

                         (2)  Options and Convertible Securities. The
                              ----------------------------------
consideration per share received by the corporation for Additional Shares of
Common Stock deemed to have been issued pursuant to Section 3(d)(iii)(1) above,
relating to Options and Convertible Securities shall be determined by dividing

                              (x)  the total amount, if any, received or
receivable by the corporation as consideration for the issue of such Options or
Convertible Securities, plus the minimum aggregate amount of additional
consideration (as set forth in the instruments relating thereto, without regard
to any provision contained therein for a subsequent adjustment of such
consideration until such subsequent adjustment occurs) payable to the
corporation upon the exercise of such Options or the conversion or exchange of
such Convertible Securities, or in the case of Options for Convertible
Securities, the exercise of such Options for Convertible Securities and the
conversion or exchange of such Convertible Securities, by

                              (y)  the maximum number of shares of Common Stock
(as set forth in the instruments relating thereto, without regard to any
provision contained therein for a subsequent adjustment of such number until
such subsequent adjustment occurs) issuable upon the exercise of such Options or
the conversion or exchange of such Convertible Securities.

                    (i)  Stock Dividends, Distributions or Subdivisions. In the
                         ----------------------------------------------
event the corporation shall issue Additional Shares of Common Stock pursuant to
Section 3(d)(iii)(2) hereof in a stock dividend, stock distribution or
subdivision, the Conversion Price in effect immediately prior to such stock
dividend, stock distribution or subdivision shall, concurrently with the
effectiveness of such stock dividend, stock distribution or subdivision, be
proportionately decreased.

                    (ii) Combinations or Consolidations. In the event the
                         ------------------------------
outstanding shares of Common Stock shall be combined or consolidated, by
reclassification or otherwise, into a lesser number of shares of Common Stock,
the Conversion Price in effect immediately prior to such combination or
consolidation shall, concurrently with the effectiveness of such combination or
consolidation, be proportionately increased.

          (f)  Adjustment for Merger or Reorganization.  In case of any
               ---------------------------------------
consolidation or merger of the corporation with or into another corporation or
the conveyance of all or substantially all of the assets of the corporation to
another corporation, each share of Class D Preferred 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

                                       37
<PAGE>

deliverable upon conversion of such Class D Preferred would have been entitled
upon such consolidation, merger or conveyance; and, in any such case,
appropriate adjustment (as determined by the Board of Directors) shall be made
in the application of the provisions herein set forth with respect to the rights
and interest thereafter of the holders of the Class D Preferred, to the end that
the provisions set forth herein (including provisions with respect to changes in
and other adjustments of the Conversion Price) shall thereafter be applicable,
as nearly as reasonably may be, in relation to any shares of stock or other
property thereafter deliverable upon the conversion of the Class D Preferred.

reorganization, merger or consolidation of the corporation or the sale of all
or, substantially all its assets and properties as such events are more fully
set forth in the first paragraph of this Section 3(f), shall have the option of
electing treatment of his shares of Class D Preferred under either this Section
3(f) or Section 2 hereof, notice of which election shall be submitted in writing
to the corporation at its principal offices no later than five (5) days before
the effective date of such event.

          (g)  No Impairment.  The corporation will not, by amendment of its
               -------------
Restated Articles of Organization or through any reorganization, 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 the corporation but
will at all times in good faith assist in the carrying out of 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
Class D Preferred against impairment.

          (h)  Certificate as to Adjustments.  Upon the occurrence of each
               -----------------------------
adjustment or readjustment of the Conversion Price pursuant to this Section 3,
the corporation at its expense shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and furnish to each holder of
Class D Preferred a certificate setting forth such adjustment or readjustment
and showing in detail the facts upon which such adjustment or readjustment is
based.  The corporation shall, upon the written request at any time of any
holder of Class D Preferred, furnish or cause to be furnished to such holder a
like certificate setting forth (i) such adjustments and readjustments, (ii) the
Conversion Price at the time in effect, and (iii) the number of shares of Common
Stock and the amount if any, of other property which at the time would be
received upon the conversion of Class D Preferred.

          (i)  Notice of Record Date.  In the event of (i) any taking by the
               ---------------------
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 which is the same as cash dividends paid in
previous quarters) or other distribution, or (ii) any capital reorganization of
the corporation, any reclassification or recapitalization of the capital stock
of the corporation, any merger or consolidation of the corporation, and any
transfer of all or substantially all of the assets of the corporation to any
other corporation, or any other entity or person, or any voluntary or
involuntary dissolution, liquidation or winding-up of the corporation, the
corporation shall mail to each holder of Class D Preferred at least 20 days
prior to the record date specified therein, a notice specifying (A) the date on
which any such record is to be taken for the purpose of such

                                       38
<PAGE>

dividend or distribution and a description of such dividend or distribution, (B)
the date on which any such reorganization, reclassification, transfer,
consolidation, merger, dissolution, liquidation or winding-up is expected to
become effective, and (C) the time if any, that is to be fixed, as to when the
holders of record of Common Stock (or other securities) shall be entitled to
exchange their shares of Common Stock (or other securities) for securities or
other property deliverable upon such reorganization, reclassification, transfer,
consolidation, merger, dissolution liquidation or winding-up.

          (j)  Common Stock Reserved.  The corporation shall reserve and keep
               ---------------------
available out of its authorized but unissued Common Stock such number of shares
of Common Stock as shall from time to time be sufficient to effect conversion of
the Class D Preferred.

     Section 4.  Redemption.
     ----------  ----------

          (a)  On November 21, 2002 (the "Commencement Date") and on the first
and second anniversaries thereof, the corporation shall offer to redeem from
each holder of shares of Class D Preferred a maximum of thirty-three and a third
percent (33 1/3%), sixty-six and two-thirds percent (66 2/3%) and one hundred
percent (100%), respectively, of the total number of shares of Class D Preferred
held by such shareholder prior to the Commencement Date, at a price for each
share tendered for redemption equal to the greater of (i) $1.80 plus an amount
equal to all declared but unpaid dividends payable in accordance with Section 6
hereof or (ii) the fair market value per share (the "Redemption Price");
provided, that any shares of Class D Preferred redeemed hereunder in any
previous years shall reduce the maximum amount of Class D Preferred which the
corporation may be requested to redeem in any then current year.  Fair market
value shall mean the fair market value per share as determined in good faith by
the Board of Directors, provided that if holders of more than fifty percent of
the outstanding Class D Preferred disagree with such determination, the fair
market value shall be determined (i) by an independent investment banking firm
mutually selected by such holders and the Board of Directors, or (ii) failing
such agreement within thirty days, by two such firms, one selected by the Board
of Directors and one by such holders, or (iii) failing agreement by such two
firms within thirty days, by a third such firm mutually selected by such firms.
The fees of all such investment banking firms shall be borne in equal halves by
the corporation and such holders.  The corporation shall provide access to all
such information as is reasonably necessary for such firms to determine fair
market value.  The corporation shall offer to redeem shares of Class D Preferred
by giving written notice thereof to each holder of shares of Class D Preferred
eligible for redemption, which notice shall state the number of shares of Class
D Preferred eligible to be redeemed by such holder and shall specify a
redemption date not less than forty-five (45) days nor more than sixty (60) days
after the date of such written notice.  Any holder of shares of Class D
Preferred eligible to be redeemed may redeem such shares by giving written
notice thereof to the corporation, and to each other holder of shares of Class D
Preferred, no less than 15 days prior to the redemption date specified in the
corporation's written offer of redemption, and by surrendering to the
corporation on or before the redemption date the share certificates for the
number of shares of Class D Preferred to be redeemed.  If fewer than all of the
shares represented by such certificates are redeemed, one or more new
certificates shall be issued for the unredeemed shares as promptly as possible.
Notwithstanding the foregoing, the holders of more

                                       39
<PAGE>

than fifty percent (50%) of all Class D Preferred in the aggregate shall have
the right to postpone for a specified period of time or waive such rights of
redemption of all holders by written notice to the corporation and to all such
holders given at least fifteen (15) days prior to the scheduled date of
redemption.

          (b)  In the event of a sale of all or substantially all the assets of
the corporation, then the corporation shall offer to redeem not fewer than all
the shares of Class D Preferred held by all holders of shares of Class D
Preferred on the date the corporation fixes as the date to mail or otherwise
send out its offer of redemption, at the Redemption Price.  The corporation
shall offer to redeem shares of Class D Preferred by giving written notice
thereof to each holder of shares of such Class D Preferred, which notice shall
be sent not less than twenty (20) days before the scheduled date of consummation
of the transaction described above.  Such notice of redemption shall state the
number of shares of Class D Preferred eligible to be redeemed by such holder and
shall specify a redemption date not less than twenty (20) days nor more than
sixty (60) days after the date of such written notice.  Any holder of shares of
Class D Preferred may redeem such shares by giving written notice thereof to the
corporation not less than ten (10) days prior to the redemption date specified
in the corporation's written offer of redemption, and by surrendering to the
corporation on or before the redemption date the share certificates for the
number of shares of such Class D Preferred to be redeemed.

     Section 5.  Voting Rights.
     ----------  -------------

          (a)  The holders of shares of Class D Preferred shall be entitled to
notice of any shareholders' meeting and to vote upon any matter submitted to the
shareholders for a vote, as though the Common Stock, the Class A Preferred, the
Class B Preferred, the Class C Preferred and the Class D Preferred constituted a
single class of stock, except with respect to those matters on which the
Massachusetts Corporation Law requires that a vote must be by a separate class
or classes or by separate series.  For all votes, holders of each class of Class
D Preferred Stock shall have that number of votes per share as is equal to the
number of shares of Common Stock into which each such share of Class D Preferred
held by such holder is convertible on the record date for the determination of
stockholders entitled to vote at the meeting or on the date of any written
consent.

          (b)  The holders of Class D Preferred, shall be entitled to vote upon
the election of directors on the following basis:  So long as at least 50,000
shares of Class D Preferred shall be outstanding, the holders of Class D
Preferred issued and outstanding, voting as a single class, shall be entitled to
one director.

     Section 6.  Dividend Rights.
     ----------  ---------------

          (a)  The holders of the then outstanding shares of Class D Preferred
shall be entitled to receive, when and as declared by the Board Directors, out
of funds legally available therefor, non-cumulative cash dividends at the annual
rate of $.144 per share payable at a rate of $.036 per share per calendar
quarter.  The corporation's obligation to pay such dividends shall commence
after the first calendar quarter when the corporation's net after tax income,
calculated

                                       40
<PAGE>

in accordance with generally accepted accounting principles, exceeds five times
such quarterly dividend on all then outstanding Class D Preferred and on all
then outstanding shares of any other class of preferred stock of the
corporation.

          (b)  Notwithstanding any provisions in Section 6(a) hereof, dividends
which have been declared on any Class D Preferred but have not been paid prior
to an automatic conversion pursuant to Section 3(b) hereof shall be payable
within 30 days of the Closing, as defined in Section 3(b), to each person who
holds of record Class D Preferred immediately prior to the automatic conversion.

          (c)  When and as dividends are declared payable in cash, property or
shares of the corporation's capital stock on shares of Common Stock, the
corporation shall (except as otherwise provided in Section 3) declare at the
same time and pay to each holder of Class D Preferred a dividend equal to the
dividend which would have been payable to such holder if the shares of Class D
Preferred held by such holder had been converted into Common Stock on the record
date for the determination of holders of Common Stock entitled to receive such
dividend.

     Section 7.  Covenants.  So long as at least 50,000 shares of Class D
     ----------  ---------
Preferred shall be outstanding, the corporation shall not, without first
obtaining the affirmative vote or written consent of not less than sixty-six
percent (66%) of the outstanding shares of Class D Preferred:

          (a)  amend or repeal any provision of, or add any provision to, the
corporation's Restated Articles of Organization or By-Laws if such action would
alter or change the preferences, rights, privileges or powers of, or the
restrictions provided for the benefit of, Class D Preferred generally;

          (b)  reclassify any Common Stock into shares having any preference or
priority as to dividends or assets superior to or on a parity with any such
preference or priority of the Class D Preferred;

          (c)  pay or declare any dividend or distribution on any shares of
Common Stock or apply any of its assets to the redemption, retirement, purchase
or other acquisition directly or indirectly, through subsidiaries, if any, or
otherwise, of any shares of Common Stock except from officers, directors or
employees of or consultants to the corporation upon termination of employment
and except pursuant to the corporation's rights of first refusal;

          (d)  create any other class or classes of stock or series of capital
stock;

          (e)  authorize any merger or consolidation of the corporation with or
into any other corporation or entity (except into or with a wholly-owned
subsidiary corporation with the requisite shareholder approval), or authorize
the sale of substantially all of the assets of the corporation; or

          (f)  voluntarily liquidate, dissolve or wind up.

                            CLASS E PREFERRED STOCK

     Section 1.  Designation.  Eleven Million (11,000,000) shares of the
     ---------   -----------
corporation's authorized but unissued shares of Preferred Stock are hereby
designated as "Class E Preferred Stock".  Such Class E Preferred Stock (the
"Class E Preferred") shall have the relative rights and preferences set forth
below.

     Section 2.  Liquidation Rights.
     ---------   ------------------

          (a)  Payment to Holders of Class E Preferred Stock Upon Liquidation.
               --------------------------------------------------------------
In the event of any voluntary or involuntary liquidation, dissolution or
winding-up of the affairs of the corporation, the holder of each share of Class
E Preferred shall be entitled to receive, prior and in preference to any
distribution of any of the assets or surplus funds of the corporation to the
holders of the Class A Preferred and the Common Stock of the corporation by
reason of their ownership thereof, an amount equal to (i) $2.25 per share of
Class E Preferred plus (ii) an amount equal to all declared but unpaid dividends
to and including the date full payment shall be tendered to the holder of the
Class E Preferred with respect to such liquidation, dissolution or winding-up.

All of the preferential amounts to be paid to the holders of the Class E
Preferred under this Section 2(a) shall be paid or set apart for payment before
the payment or setting apart for payment of any amount for, or the distribution
of any assets of the corporation to, the holders of the Class A Preferred and
Common Stock in connection with such liquidation, dissolution or winding-up.  If
the assets or surplus funds to be distributed to the holders of the Class B
Preferred, the Class D Preferred and the Class E Preferred are insufficient to
permit the payment to such holders of their full preferential amount, the assets
and surplus funds legally available for distribution shall be distributed
ratably among the holders of Class E Preferred, Class D Preferred and Class B
Preferred in proportion to the full preferential amount each such holder is
otherwise entitled to receive.

          (b)  Payment to Holders of Class E Preferred, Class D Preferred and
               --------------------------------------------------------------
Common Stock.  After the payment or the setting apart of payment to the holders
- ------------
of the Class A Preferred, the Class B Preferred, the Class D Preferred and the
Class E Preferred of the preferential amounts so payable to them, all remaining
assets of the corporation shall be distributed among the holders of the Class E
Preferred, the Class D Preferred and the holders of the Common Stock ratably in
proportion to the number of shares of Class D Preferred, Class E Preferred and
Common Stock (and, in the case of Class D Preferred and the Class E Preferred,
the number of shares of Common Stock into which each such share of Class D
Preferred or Class E Preferred, as the case may be, held by such holder could be
converted on the record date for the determination of rights of stockholders to
distributions under this Section 2) held by them.

          (c)  No Liquidation Preference After Conversion.  Upon conversion of
               ------------------------------------------
shares of Class E Preferred into shares of Common Stock pursuant to Section 3
below, the holder of such Common Stock shall not be entitled to any preferential
payment or distribution in case of any

                                       42
<PAGE>

liquidation, dissolution or winding-up of corporation, but shall share ratably
in any distribution of the assets of the corporation to all holders of Common
Stock.

          (d)  Distributions Other than Cash.  Whenever the distribution
               -----------------------------
provided for in this Section 2 shall be payable in property other than cash, the
value of such distribution shall be the fair market value of such property as
determined in good faith by the Board of Directors of the corporation.

          (e)  Merger as Liquidation, etc.  The merger or consolidation of the
               --------------------------
corporation into or with another corporation (other than a wholly-owned
subsidiary of this corporation in a merger in which this corporation is the
surviving corporation and its Articles of Organization remain unchanged), or the
sale of all or substantially all of the assets of the corporation (other than to
a wholly-owned subsidiary of this corporation) shall be deemed to be a
liquidation, dissolution or winding-up of the corporation for purposes of this
Section 2 unless the holders of at least 51% of the then outstanding shares of
Class E Preferred (voting as a single class) 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(f) shall apply.  The amount deemed distributed to the holders of Class
E Preferred upon any such merger or consolidation shall be the cash or the value
of the property, rights or securities distributed to such holders by the
acquiring person, firm or other entity.  The value of such property, rights or
other securities shall be determined in good faith by the Board of Directors of
the corporation.

          (f)  Notice and Opportunity to Exercise Conversion Rights.
               ----------------------------------------------------
Notwithstanding anything to the contrary that may be inferred from the
provisions of this Section 2, each holder of shares of Class E Preferred shall
be entitled to receive notice from the corporation pursuant to Section 3(i)
hereof of any proposed liquidation, dissolution or winding-up of the corporation
at least 20 days prior to the date on which any such liquidation, dissolution or
winding-up of the corporation is scheduled to occur and, at any time prior to
any such liquidation, dissolution or winding-up of the corporation, to convert
any or all of such holder's shares of Class E Preferred into shares of Common
Stock pursuant to Section 3 hereof.

     Section 3.  Conversion.  The holders of the Class E Preferred shall have
     ---------   ----------
conversion rights as follows (the "Conversion Rights"):

          (a)  Right to Convert.  Each share of Class E Preferred shall be
               ----------------
convertible, without the payment of any additional consideration by the holder
thereof and at the option of the holder thereof, at any time after the date of
issuance of such share, at the office of the corporation or any transfer agent
for the Class E Preferred, into such fully paid and nonassessable shares of
Common Stock, as is determined by dividing two dollars and twenty-five cents
($2.25) by the Conversion Price, determined as hereinafter provided, in effect
at the time of conversion.  The Conversion Price at which shares of Common Stock
shall be deliverable upon conversion without the payment of any additional
consideration by the holder thereof (the "Conversion Price") shall initially be
two dollars and twenty-five cents ($2.25) per share of Common Stock.  Such
initial Conversion Price shall be subject to adjustment, in order to adjust the
number of shares of Common Stock into which the Class E Preferred is
convertible, as hereinafter provided.

                                       43
<PAGE>

          (b)  Automatic Conversion.
               --------------------

               (i)  Upon Qualifying Public Offerings. Each share of Class E
                    --------------------------------
Preferred shall automatically be converted into shares of Common Stock at the
then effective Conversion Price upon the closing of a firm commitment
underwritten public offering pursuant to an effective registration statement
under the Securities Act of 1933, as amended, covering the offer and sale of
Common Stock for the account of the corporation to the public at a public
offering price of at least $4.50 per share (with such amount to be appropriately
adjusted in the event of any stock dividend, stock distribution or subdivision
as provided in subparagraph (e) hereof) and having an aggregate offering price
to the public resulting in gross proceeds to the corporation of not less than
$15,000,000 (in the event of which offering, the person(s) entitled to receive
the Common Stock issuable upon such conversion of the Class E Preferred shall
not be deemed to have converted that Class E Preferred until immediately prior
to the closing of such offering). Each person who holds of record Class E
Preferred immediately prior to such automatic conversion shall be entitled to
all dividends which have accrued to the time of the automatic conversion, but
have not been paid on the Class E Preferred, pursuant to Section 6 hereof. Such
dividends shall be paid to all such holders within 30 days of the automatic
conversion.

               (ii) Upon Conversion of 90% of Class E Preferred. Each share of
                    -------------------------------------------
Class E Preferred then outstanding shall automatically be converted into shares
of Common Stock at the then-effective Conversion Price, upon the conversion of
ninety percent (90%) or more of the authorized Class E Preferred. Such
conversion shall be deemed to have occurred on the date upon which the aggregate
number of shares of Class E Preferred which have been converted to Common Stock
equals or exceeds ninety percent (90%) of the authorized Class E Preferred.

          (c)  Mechanics of Conversion.  No fractional shares of Common Stock
               -----------------------
shall be issued upon conversion of the Class E Preferred.  In lieu of any
fractional shares to which the holder would otherwise be entitled, the
corporation shall pay cash equal to such fraction multiplied by the then
effective Conversion Price.  Before any holder of Class E Preferred shall be
entitled to convert the same into full shares of Common Stock, he shall
surrender the certificate or certificates therefor, duly endorsed, at the office
of the corporation or of any transfer agent for the Class E Preferred, and shall
give written notice to the corporation at such office that he elects to convert
the same and shall state therein his name or the name or names of his nominees
in which he wishes the certificate or certificates for shares of Common Stock to
be issued.  The corporation shall, as soon as practicable thereafter, issue and
deliver at such office to such holder of Class E Preferred, or to his nominee or
nominees, a certificate or certificates for the number of shares of Common Stock
to which he shall be entitled as aforesaid, together with cash in lieu of any
fraction of a share.  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 Class E Preferred to be converted, and the person or persons entitled
to receive the shares of Common Stock issuable upon conversion shall be treated
for all purposes as the record holder or holders of such shares of Common Stock
on such date.

the number of shares of Common Stock into which the Class E Preferred is
convertible shall be made, by adjustment in the Conversion Price of Class E
Preferred in respect of the issuance of Additional Shares of Common Stock or
otherwise, unless the consideration per share for an Additional Share of Common
Stock issued or deemed to be issued by the corporation is less than the
Conversion Price in effect on the date of, and immediately prior to, the issue
of such Additional Share.

                    (iii) Issue of Securities Deemed Issue of Additional Shares

of Common Stock.
- ---------------

                          (1) Options and Convertible Securities. In the event
                              ----------------------------------
the corporation at any time or from time to time after the Original Issue Date
shall issue any Options or Convertible Securities or shall fix a record date for
the determination of holders of any class of securities entitled to receive any
such Options or Convertible Securities, then the maximum number of shares (as
set forth in the instrument relating thereto without regard to any provisions
contained therein for a subsequent adjustment of such number) of Common Stock
issuable upon the exercise of such Options or, in the case of Convertible
Securities and Options therefor, the conversion or exchange of such Convertible
Securities, shall be deemed to be Additional Shares of Common Stock issued as of
the time of such issue or, in case such record date shall have been fixed, as of
the close of business on such record date, provided that Additional Shares of
Common Stock shall not be deemed to have been issued unless the consideration
per share (determined pursuant to Section 3(d)(v) hereof), of such Additional
Shares of Common Stock would be less than the Conversion Price in effect on the
date of and immediately prior to such issue, or such record date, as the case
may be, and provided further that in any such case in which Additional Shares of
Common Stock are deemed to be issued:

                              (A)  no further adjustment in the Conversion Price
shall be made upon the subsequent issue of Convertible Securities or shares of
Common Stock upon the exercise of such Options or conversion or exchange of such
Convertible Securities;

                              (B)  if such Options or Convertible Securities by
their terms provide, with the passage or time or otherwise, for any increase in
the consideration payable to the corporation, or decrease in the number of'
shares of Common Stock issuable, upon the exercise, conversion or exchange
thereof, the Conversion Price computed upon the original issue thereof (or upon
the occurrence of a record date with respect thereto), and any subsequent
adjustments based thereon, shall, upon any such increase or decrease becoming
effective, be recomputed to reflect such increase or decrease insofar as it
affects such Options or the rights of conversion or exchange under such
Convertible Securities;

                              (C)  upon the expiration of any such Options or
any rights of conversion or exchange under such Convertible Securities which
shall not have been exercised, the Conversion Price computed upon the original
issue thereof (or upon the occurrence of a record date with respect thereto),
and any subsequent adjustments based thereon, shall, upon such expiration, be
re-computed as if:

                                       46
<PAGE>

                                   (I)  in the case of Convertible Securities or
Options for Common Stock, the only Additional Shares of Common Stock issued were
the shares of Common Stock, if any, actually issued upon the exercise of such
Options or the conversion or exchange of such Convertible Securities and the
consideration received therefor was the consideration actually received by the
corporation for the issue of all such Options, whether or not exercised, plus
the consideration actually received by the corporation upon such exercise, or
for the issue of all such Convertible Securities which were actually converted
or exchanged, plus the additional consideration, if any, actually received by
the corporation upon such conversion or exchange, and

                                   (II) in the case of Options for Convertible
Securities, only the Convertible Securities, if any, actually issued upon the
exercise thereof were issued at the time of issue of such Options, and the
consideration received by the corporation for the Additional Shares of Common
Stock deemed to have been then issued was the consideration actually received by
the corporation for the issue of all such Options, whether or not exercised,
plus the consideration deemed to have been received by the corporation
(determined pursuant to Section 3(d)(v) hereof) upon the issue of the
Convertible Securities with respect to which such Options were actually
exercised;

                              (D)  no readjustment pursuant to clause (B) or (C)
above shall have the effect of increasing the Conversion Price to an amount
which exceeds the lower of (i) the Conversion Price on the original adjustment
date, or (ii) the Conversion Price that would have resulted from any issuance of
Additional Shares of Common Stock between the original adjustment date and such
readjustment date;

                              (E)  in the case of any Options which expire by
their terms not more than 30 days after the date of issue thereof, no adjustment
of the Conversion Price shall be made until the expiration or exercise of all
such Options, whereupon such adjustment shall be made in the same manner
provided in clause (C) above; and

                              (F)  if such record date shall have been fixed and
such Options or Convertible Securities are not issued on the date fixed
therefor, the adjustment previously made in the Conversion Price which became
effective on such record date shall be canceled as of the close of business on
such record date and thereafter the Conversion Price shall be adjusted pursuant
to this subparagraph 3(d)(iii) as of the actual date of their issuance.

                         (2)  Stock Dividends, Stock Distributions and
                              ----------------------------------------
Subdivisions. In the event the corporation at any time or from time to time
- ------------
after the Original Issue Date shall declare or pay any dividend or make any
other distribution on the Common Stock payable in Common Stock, or effect a
subdivision of the outstanding shares of Common Stock (by reclassification or
otherwise than by payment of a dividend in Common Stock), then and in any such
event, Additional Shares of Common Stock shall be deemed to have been issued:

                                       47
<PAGE>

                              (A)  in the case of any such dividend or
distribution, immediately after the close of business on the record date for the
determination of holders of any class of securities entitled to receive such
dividend or distribution, or

                              (B)  in the case of any such subdivision, at the
close of business on the date immediately prior to the date upon which such
corporate action becomes effective.

     If such record date shall have been fixed and such dividend shall not have
been fully paid on the date fixed therefor, the adjustment previously made in
the Conversion Price which became effective on such record date shall be
canceled as of the close of business on such record date, and thereafter the
Conversion Price shall be adjusted pursuant to this subparagraph 3(d)(iii) as of
the time of actual payment of such dividend.

                    (iv)  Adjustment of Conversion Price Upon Issuance of
                          -----------------------------------------------
Additional Shares of Common Stock. In the event the corporation shall issue
- ---------------------------------
Additional Shares of Common Stock (including Additional Shares of Common Stock
deemed to be issued pursuant to Section 3(d) (iii) hereof, but excluding
Additional Shares of Common Stock issued pursuant to Section 3(d)(iii)(2), which
event is dealt with in Section (3)(e) hereof) without consideration or for a
consideration per share less than the Conversion Price in effect on the date of
and immediately prior to such issue, then and in such event, such Conversion
Price shall be reduced, concurrently with such issue in order to increase the
number of shares of Common Stock into which the Class E Preferred is
convertible, to a price (calculated to the nearest cent) determined by
multiplying such Conversion Price by a fraction (x) the numerator of which shall
be (1) the number of shares of Common Stock outstanding immediately prior to
such issue (including shares of Common Stock issuable upon conversion of any
outstanding Class A Preferred, Class B Preferred, Class D Preferred, Class E
Preferred or Convertible Securities) plus (2) the number of shares of Common
Stock which the aggregate consideration received by the corporation for the
total number of Additional Shares of Common Stock so issued would purchase at
such Conversion Price, and (y) the denominator of which shall be (1) the number
of shares of Common Stock outstanding immediately prior to such issue (including
shares of Common Stock issuable upon conversion of any outstanding Class A
Preferred, Class B Preferred, Class D Preferred, Class E Preferred or
Convertible Securities), plus (2) the number of such Additional Shares of Common
Stock so issued, provided that the Conversion Price shall not be so reduced at
such time if the amount of such reduction would be an amount less than $0.05,
but any such amount shall be carried forward and reduction with respect thereto
made at the time of and together with any subsequent reduction which, together
with such amount and any other amount or amounts so carried forward, shall
aggregate $0.05 or more.

                    (v)   Determination of Consideration. For purposes of this
                          ------------------------------
Section 3(d), the consideration received by the corporation for the issue of any
Additional Shares of Common Stock shall be computed as follows:

                          (1) Cash and Property.  Such consideration shall:
                              -----------------

                                       48
<PAGE>

                              (A)  insofar as it consists of cash, be computed
at the aggregate amount of cash received by the corporation excluding amounts
paid or payable for accrued interest or accrued dividends;

                              (B)  insofar as it consists of property other than
cash, be computed at the fair value thereof at the time of such issue, as
determined in good faith by the Board of Directors; and

                              (C)  in the event Additional Shares of Common
Stock are issued together with other shares or securities or other assets of the
corporation for consideration which covers both, be the proportion of such
consideration so received, computed as provided in clauses (A) and (B) above, as
determined in good faith by the Board of Directors.

                         (2)  Options and Convertible Securities. The
                              ----------------------------------
consideration per share received by the corporation for Additional Shares of
Common Stock deemed to have been issued pursuant to Section 3(d)(iii)(1) above,
relating to Options and Convertible Securities shall be determined by dividing

                              (x)  the total amount, if any, received or
receivable by the corporation as consideration for the issue of such Options or
Convertible Securities, plus the minimum aggregate amount of additional
consideration (as set forth in the instruments relating thereto, without regard
to any provision contained therein for a subsequent adjustment of such
consideration until such subsequent adjustment occurs) payable to the
corporation upon the exercise of such Options or the conversion or exchange of
such Convertible Securities, or in the case of Options for Convertible
Securities, the exercise of such Options for Convertible Securities and the
conversion or exchange of such Convertible Securities, by

                              (y)  the maximum number of shares of Common Stock
(as set forth in the instruments relating thereto, without regard to any
provision contained therein for a subsequent adjustment of such number until
such subsequent adjustment occurs) issuable upon the exercise of such Options or
the conversion or exchange of such Convertible Securities.

          (e)  Adjustment for Dividends, Distributions, Subdivisions,
               ------------------------------------------------------
Combinations or Consolidations of Common Stock.
- ----------------------------------------------

                    (i)  Stock Dividends, Distributions or Subdivisions. In the
                         ----------------------------------------------
event the corporation shall issue Additional Shares of Common Stock pursuant to
Section 3(d)(iii)(2) hereof in a stock dividend, stock distribution or
subdivision, the Conversion Price in effect immediately prior to such stock
dividend, stock distribution or subdivision shall, concurrently with the
effectiveness of such stock dividend, stock distribution or subdivision, be
proportionately decreased.

                    (ii) Combinations or Consolidations. In the event the
                         ------------------------------
outstanding shares of Common Stock shall be combined or consolidated, by
reclassification or otherwise, into a lesser number of shares of Common Stock,
the Conversion Price in effect immediately prior to

                                       49
<PAGE>

such combination or consolidation shall, concurrently with the effectiveness of
such combination or consolidation, be proportionately increased.

          (f)  Adjustment for Merger or Reorganization.  In case of any
               ---------------------------------------
consolidation or merger of the corporation with or into another corporation or
the conveyance of all or substantially all of the assets of the corporation to
another corporation, each share of Class E Preferred 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 Class E Preferred would have been entitled
upon such consolidation, merger or conveyance; and, in any such case,
appropriate adjustment (as determined by the Board of Directors) shall be made
in the application of the provisions herein set forth with respect to the rights
and interest thereafter of the holders of the Class E Preferred, to the end that
the provisions set forth herein (including provisions with respect to changes in
and other adjustments of the Conversion Price) shall thereafter be applicable,
as nearly as reasonably may be, in relation to any shares of stock or other
property thereafter deliverable upon the conversion of the Class E Preferred.

     Each holder of Class E Preferred upon the occurrence of a capital
reorganization, merger or consolidation of the corporation or the sale of all
or, substantially all its assets and properties as such events are more fully
set forth in the first paragraph of this Section 3(f), shall have the option of
electing treatment of his shares of Class E Preferred under either this Section
3(f) or Section 2 hereof, notice of which election shall be submitted in writing
to the corporation at its principal offices no later than five (5) days before
the effective date of such event.

          (g)  No Impairment.  The corporation will not, by amendment of its
               -------------
Restated Articles of Organization or through any reorganization, 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 the corporation but
will at all times in good faith assist in the carrying out of 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
Class E Preferred against impairment.

          (h)  Certificate as to Adjustments.  Upon the occurrence of each
               -----------------------------
adjustment or readjustment of the Conversion Price pursuant to this Section 3,
the corporation at its expense shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and furnish to each holder of
Class E Preferred a certificate setting forth such adjustment or readjustment
and showing in detail the facts upon which such adjustment or readjustment is
based.  The corporation shall, upon the written request at any time of any
holder of Class E Preferred, furnish or cause to be furnished to such holder a
like certificate setting forth (i) such adjustments and readjustments, (ii) the
Conversion Price at the time in effect, and (iii) the number of shares of Common
Stock and the amount if any, of other property which at the time would be
received upon the conversion of Class E Preferred.

          (i)  Notice of Record Date.  In the event of (i) any taking by the
               ---------------------
corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof

                                       50
<PAGE>

who are entitled to receive any dividend (other than a cash dividend which is
the same as cash dividends paid in previous quarters) or other distribution, or
(ii) any capital reorganization of the corporation, any reclassification or
recapitalization of the capital stock of the corporation, any merger or
consolidation of the corporation, and any transfer of all or substantially all
of the assets of the corporation to any other corporation, or any other entity
or person, or any voluntary or involuntary dissolution, liquidation or winding-
up of the corporation, the corporation shall mail to each holder of Class E
Preferred at least 20 days prior to the record date specified therein, a notice
specifying (A) the date on which any such record is to be taken for the purpose
of such dividend or distribution and a description of such dividend or
distribution, (B) the date on which any such reorganization, reclassification,
transfer, consolidation, merger, dissolution, liquidation or winding-up is
expected to become effective, and (C) the time if any, that is to be fixed, as
to when the holders of record of Common Stock (or other securities) shall be
entitled to exchange their shares of Common Stock (or other securities) for
securities or other property deliverable upon such reorganization,
reclassification, transfer, consolidation, merger, dissolution, liquidation or
winding-up.

          (j)  Common Stock Reserved.  The corporation shall reserve and keep
               ---------------------
available out of its authorized but unissued Common Stock such number of shares
of Common Stock as shall from time to time be sufficient to effect conversion of
the Class E Preferred.

     Section 4.  Redemption.
     ---------   ----------

          (a)  On October 21, 2003 (the "Commencement Date") and on the first
and second anniversaries thereof, the corporation shall offer to redeem from
each holder of shares of Class E Preferred a maximum of thirty-three and a third
percent (33 1/3%), sixty-six and two-thirds percent (66 2/3%) and one hundred
percent (100%), respectively, of the total number of shares of Class E Preferred
held by such shareholder prior to the Commencement Date, at a price for each
share tendered for redemption equal to the greater of (i) $2.25 plus an amount
equal to all declared but unpaid dividends payable in accordance with Section 6
hereof and (ii) the fair market value per share (the "Redemption Price");
provided, that any shares of Class E Preferred redeemed hereunder in any
previous years shall reduce the maximum amount of Class E Preferred which the
corporation may be requested to redeem in any then current year.  Fair market
value shall mean the fair market value per share as determined in good faith by
the Board of Directors, provided that if holders of more than fifty percent
(50%) of the outstanding Class E Preferred disagree with such determination, the
fair market value shall be determined (i) by an independent investment banking
firm mutually selected by such holders and the Board of Directors, or (ii)
failing such agreement within thirty days, by two such firms, one selected by
the Board of Directors and one by such holders, or (iii) failing agreement by
such two firms within thirty days, by a third such firm mutually selected by
such firms.  The fees of all such investment banking firms shall be borne in
equal halves by the corporation and such holders.  The corporation shall provide
access to all such information as is reasonably necessary for such firms to
determine fair market value.  The corporation shall offer to redeem shares of
Class E Preferred by giving written notice thereof to each holder of shares of
Class E Preferred eligible for redemption, which notice shall state the number
of shares of Class E Preferred eligible to be redeemed by such holder and shall
specify a redemption date not less than forty-five (45) days

                                       51
<PAGE>

nor more than sixty (60) days after the date of such written notice. Any holder
of shares of Class E Preferred eligible to be redeemed may redeem such shares by
giving written notice thereof to the corporation, and to each other holder of
shares of Class E Preferred, no less than 15 days prior to the redemption date
specified in the corporation's written offer of redemption, and by surrendering
to the corporation on or before the redemption date the share certificates for
the number of shares of Class E Preferred to be redeemed. If fewer than all of
the shares represented by such certificates are redeemed, one or more new
certificates shall be issued for the unredeemed shares as promptly as possible.
Notwithstanding the foregoing, the holders of more than fifty percent (50%) of
all Class E Preferred in the aggregate shall have the right to postpone for a
specified period of time or waive such rights of redemption of all holders by
written notice to the corporation and to all such holders given at least fifteen
(15) days prior to the scheduled date of redemption.

          (b)  In the event of a sale of all or substantially all the assets of
the corporation, the corporation shall offer to redeem not fewer than all the
shares of Class E Preferred held by all holders of shares of Class E Preferred
on the date the corporation fixes as the date to mail or otherwise send out its
offer of redemption, at the Redemption Price.  The corporation shall offer to
redeem shares of Class E Preferred by giving written notice thereof to each
holder of shares of such Class E Preferred, which notice shall be sent not less
than twenty (20) days before the scheduled date of consummation of the
transaction described above.  Such notice of redemption shall state the number
of shares of Class E Preferred eligible to be redeemed by such holder and shall
specify a redemption date not less than twenty  (20) days nor more than sixty
(60) days after the date of such written notice.  Any holder of shares of Class
E Preferred may redeem such shares by giving written notice thereof to the
corporation not less than ten (10) days prior to the redemption date specified
in the corporation's written offer of redemption, and by surrendering to the
corporation on or before the redemption date the share certificates for the
number of shares of such Class E Preferred to be redeemed.

     Section 5.  Voting Rights.  The holders of shares of Class E Preferred
     ---------   -------------
shall be entitled to notice of any shareholders' meeting and to vote upon any
matter submitted to the shareholders for a vote, as though the Common Stock, the
Class A Preferred, the Class B Preferred, the Class D Preferred and the Class E
Preferred constituted a single class of stock, except with respect to those
matters on which the Massachusetts Corporation Law requires that a vote must be
by a separate class or classes or by separate series.  For all votes, holders of
Class E Preferred Stock shall have that number of votes per share as is equal to
the number of shares of Common Stock into which each such share of Class E
Preferred held by such holder is convertible on the record date for the
determination of stockholders entitled to vote at the meeting or on the date of
any written consent.

     Section 6.  Dividend Rights.
     ---------   ---------------

          (a)  The holders of the then outstanding shares of Class E Preferred
shall be entitled to receive, when and as declared by the Board Directors, out
of funds legally available therefor, non-cumulative cash dividends at the annual
rate of $.18 per share payable at a rate of $.045 per share per calendar
quarter.  The corporation's obligation to pay such dividends shall

                                       52
<PAGE>

commence after the first calendar quarter when the corporation's net after tax
income, calculated in accordance with generally accepted accounting principles,
exceeds five times such quarterly dividend on all then outstanding Class E
Preferred and on all then outstanding shares of all other classes of preferred
stock of the corporation.

          (b)  Notwithstanding any provisions in Section 6(a) hereof, dividends
which have been declared on any Class E Preferred but have not been paid prior
to an automatic conversion pursuant to Section 3(b) hereof shall be payable
within 30 days of the Closing, as defined in Section 3(b), to each person who
holds of record Class E Preferred immediately prior to the automatic conversion.

          (c)  When and as dividends are declared payable in cash, property or
shares of the corporation's capital stock on shares of Common Stock, the
corporation shall (except as otherwise provided in Section 3) declare at the
same time and pay to each holder of Class E Preferred a dividend equal to the
dividend which would have been payable to such holder if the shares of Class E
Preferred held by such holder had been converted into Common Stock on the record
date for the determination of holders of Common Stock entitled to receive such
dividend.

     Section 7.  Covenants.  So long as at least 50,000 shares of Class E
     ---------   ---------
Preferred shall be outstanding, the corporation shall not, without first
obtaining the affirmative vote or written consent of not less than sixty-six
percent (66%) of the outstanding shares of Class E Preferred:

          (a)  amend or repeal any provision of, or add any provision to, the
corporation's Restated Articles of Organization or By-Laws if such action would
alter or change the preferences, rights, privileges or powers of, or the
restrictions provided for the benefit of, Class E Preferred generally;

          (b)  reclassify any Common Stock into shares having any preference or
priority as to dividends or assets superior to or on a parity with any such
preference or priority of the Class E Preferred;

          (c)  pay or declare any dividend or distribution on any shares of
Common Stock or apply any of its assets to the redemption, retirement, purchase
or other acquisition directly or indirectly, through subsidiaries, if any, or
otherwise, of any shares of Common Stock except from officers, directors or
employees of or consultants to the corporation upon termination of employment
and except pursuant to the corporation's rights of first refusal;

          (d)  create any other class or classes of stock or series of capital
stock;

          (e)  authorize any merger or consolidation of the corporation with or
into any other corporation or entity (except into or with a wholly-owned
subsidiary corporation with the requisite shareholder approval), or authorize
the sale of substantially all of the assets of the corporation; or

          (f)  voluntarily liquidate, dissolve or wind up.

                            OTHER LAWFUL PROVISIONS
                            -----------------------

          (a)  The corporation may carry on any business, operation or activity
referred to in Article 2 to the same extent as might an individual, whether as
principal, agent, contractor or otherwise, and either alone or in conjunction or
a joint venture or other arrangement with any corporation, association, trust,
firm or individual.

          (b)  The corporation may carry on any business, operation or activity
through a wholly or partly owned subsidiary.

          (c)  The corporation may be a partner in any business enterprise which
it would have the power to conduct by itself.

          (d)  the directors may make, amend or repeal the bylaws in whole or in
part, except with respect to any provision thereof which by law or the bylaws
requires action by the stockholders.

          (e)  Meetings of the stockholders may be held anywhere in the United
States.

          (f)  No stockholder shall have any right to examine any property or
any books, accounts or other writings of the corporation if there is reasonable
ground for belief that such examination will for any reason be adverse to the
interests of the corporation, and a vote of the directors refusing permission to
make such examination and setting forth that in the opinion of the directors
such examination would be adverse to the interests of the corporation shall be
prima facie evidence that such examination would be adverse to the interests of
the corporation. Every such examination shall be subject to such reasonable
regulations as the directors may establish in regard thereto.

          (g)  The directors may specify the manner in which the accounts to the
corporation shall be kept and may determine what constitutes net earnings,
profits and surplus, what amounts, if any, shall be declared as dividends.
Unless the board of directors otherwise specifies, the excess of the
consideration for any share of its capital stock with par value issued by it
over such par value shall be paid-in surplus. The board of directors may
allocate to capital stock less than all of the consideration for any share of
its capital stock without par value issued by it, in which case the balance of
such consideration shall be paid-in surplus. All surplus shall be available for
any corporate purpose, including the payment of dividends.

          (h)  The purchase or other acquisition or retention by the corporation
of shares of its own capital stock shall not be deemed a reduction of its
capital stock.  Upon any reduction of capital or capital stock, no stockholder
shall have any right to demand any distribution from the

                                       54
<PAGE>

corporation, except as and to the extent that the stockholders shall have
provided at the time of authorizing such reduction.

          (i)  The directors shall have the power to fix from time to time their
compensation.  No person shall be disqualified from holding any office by reason
of any interest.  In the absence of fraud, any director, officer or stockholder
of this corporation individually, or any individual having any interest in any
concern which is a stockholder of this corporation, or any concern in which any
of such directors, officers, stockholders or individuals has any interest, may
be a party to, or may be pecuniary or otherwise interested in, any contract,
transaction or other act of this corporation, and

               (1)  such contract, transaction or act shall not be in any way
                    invalidated or otherwise affected by that fact;

               (2)  no such director, officer, stockholder or individual shall
                    be liable to account to this corporation for any profit or
                    benefit realized through any such contract, transaction or
                    act; and

               (3)  any such director of this corporation may be counted in
                    determining the existence of a quorum at any meeting of the
                    directors or of any committee thereof which shall authorize
                    any such contract, transaction or act, and may vote to
                    authorize the same;

provided, however, that any contract, transaction or act in which any director
or officer of this corporation is so interested individually or as a director,
officer, trustee or member of any concern which is not a subsidiary or affiliate
of this corporation, or in which any directors or officers are so interested as
holders, collectively, of a majority of shares of capital stock or other
beneficial interest at the time outstanding in any concern which is not a
subsidiary or affiliate of this corporation, shall be duly authorized or
ratified by a majority of the directors who are not so interested, to whom the
nature of such interest has been disclosed and who have made any findings
required by law;

          the term "interest" including personal interest and interest as a
          director, officer, stockholder, shareholder, trustee, member or
          beneficiary of any concern;

          the term "concern" meaning any corporation, association, trust,
          partnership, firm, person or other entity other than this corporation;
          and

          the phrase "subsidiary or affiliate" meaning a concern in which a
          majority of the directors, trustees, partners or controlling persons
          is elected or appointed by the directors of this corporation, or is
          constituted of the directors or officers of this corporation.

To the extent permitted by law, the authorizing or ratifying vote of the holders
of a majority of the shares of each class of the capital stock of this
corporation outstanding and entitled to vote for directors at any annual meeting
or a special meeting duly called for the purpose (whether

                                       55
<PAGE>

such vote is passed before or after judgment rendered in a suit with respect to
such contract, transaction or act) shall validate any contract, transaction or
act of this corporation, or of the board of directors or any committee thereof,
with regard to all creditors and other claimants under this corporation;
provided, however, that

          A.   with respect to the authorization or ratification of contractors,
               transactions or acts in which any of the directors, officers or
               stockholders of this corporation have an interest, the nature of
               such contracts, transactions or acts and the interest of any
               director, officer or stockholder therein shall be summarized in
               the notice of any such annual or special meeting, or in a
               statement or letter accompanying such notice, and shall be fully
               disclosed at any such meeting;

          B.   the stockholders so voting shall have made any findings required
               by law;

          C.   stockholders so interested may vote at any such meeting except to
               the extent otherwise provided by law; and

          D.   any failure of the stockholders to authorize or ratify such
               contract, transaction or act shall not be deemed in any way to
               invalidate the same or to deprive this corporation, its
               directors, officers or employees of its or their right to proceed
               with such contract, transaction or act.

No contract, transaction or act shall be avoided by reason of any provision of
this paragraph (i) which would be valid but for such provision or provisions.

         (j)   The corporation shall have all powers granted to corporations by
the laws of The Commonwealth of Massachusetts, provided that no such power shall
include any activity inconsistent with the Business Corporation Law or the
general laws of said Commonwealth.

         (k)   The corporation eliminates the personal liability of each member
of its board of directors to the corporation or its stockholders for monetary
damages for breach of fiduciary duty as a director, provided that the foregoing
shall not eliminate the liability of a director (i) for any breach of such
director's duty of loyalty to the corporation or its stockholders, (ii) for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under Section 61 or 62 of Chapter 156B of the
Massachusetts General Laws, or (iv) for any transaction from which such director
derived an improper personal benefit.

         (l)   The Directors of the corporation shall be classified with respect
to the time for which they shall severally hold office by dividing them into
three classes, each consisting of one-third, or as equal in number as possible,
of the whole number of the Board of Directors, and all Directors shall hold
office until their successors are chosen and qualified, or until their earlier
death, resignation, or removal.  The Board of Directors has adopted a vote
designating, from among its members, Directors to serve as Directors of the
first class ("Class I Directors") who will hold office until the annual meeting
in 2000 and until their successors are duly elected and qualified, Directors of
the second class ("Class II Directors") who will hold office until the

                                       56
<PAGE>

annual meeting in 2001 and until their successors are duly elected and
qualified, and Directors of the third class ("Class III Directors") who will
hold office until the annual meeting in 2002 and until their successors are duly
elected and qualified. At each annual meeting beginning in 2000, the successors
to the class of Directors whose term expires at that meeting shall be elected to
hold office for a term continuing until the annual meeting held in the third
year following the year of their election and until their successors are duly
elected and qualified.

                         AMENDED AND RESTATED BY-LAWS
                         ----------------------------

                      TELAXIS COMMUNICATIONS CORPORATION


                                   ARTICLE I

                                 STOCKHOLDERS
                                 ------------


     1.   Place of Meetings.  All meetings of stockholders shall be held at such
          -----------------
date, time and place, either within or outside of Massachusetts, as may be
designated by the Directors from time to time.

     2.   Annual Meetings.  The annual meeting of stockholders shall be held on
          ---------------
the second Monday in May in each year (or if that be a legal holiday in the
place where the meeting is to be held, on the next succeeding full business day)
at 10:00 o'clock a.m., unless a different hour and date (which date shall be
within six months after the end of the fiscal year of the corporation) is fixed
by the Directors or the President and stated in the notice of the meeting.  The
purposes for which the annual meeting is to be held, in addition to those
prescribed by law, by the Articles of Organization or by these By-laws, may be
specified by the Directors or the President. If no annual meeting is held in
accordance with the foregoing provisions, a special meeting may be held in lieu
thereof and any action taken at such meeting shall have the same effect as if
taken at the annual meeting.

     3.   Special Meetings.  Special meetings of stockholders may be called by
          ----------------
the President or by the Directors.  Upon written application of one or more
stockholders who hold at least thirty (30%) percent of the capital stock
entitled to vote at the meeting, special meetings shall be called by the Clerk,
or in the case of the death, absence, incapacity or refusal of the Clerk, by any
other officer. The call for the meeting shall state the place, date, hour and
purposes of the meeting. Business transacted at any special meeting of the
stockholders shall be limited to matters relating to the purpose or purposes
stated in the notice of meeting.

     4.   Notice of Meetings.  A written notice of every meeting of
          ------------------
stockholders, stating the place, date and hour thereof and the purposes for
which the meeting is to be held, shall be given by the Clerk or other person
calling the meeting at least seven (7) days before the meeting to each
stockholder entitled to vote thereat and to each stockholder who, by law, by the
Articles of Organization or by these By-laws, is entitled to such notice, by
leaving such notice with him or at his residence or usual place of business, or
by mailing it postage prepaid and addressed to him at his address as it appears
upon the books of the corporation. Whenever any notice is required to be given
to a stockholder by law, by the Articles of Organization or by these By-laws, no
such notice need be given if a written waiver of notice, executed before or
after the meeting by the stockholder or his attorney thereunto duly authorized,
is filed with the records of the meeting.
<PAGE>

     5.   Quorum.  Unless the Articles of Organization otherwise provide, a
          ------
majority in interest of all stock issued, outstanding and entitled to vote on
any matter shall constitute a quorum with respect to that matter; except that if
two or more classes of stock are outstanding and entitled to vote as separate
classes, then in the case of each such class a quorum shall consist of a
majority in interest of the stock of that class issued, outstanding and entitled
to vote.

     6.   Adjournments.  Any meeting of stockholders may be adjourned to any
          ------------
other time and to any other place at which a meeting of stockholders may be held
under these By-laws by the vote of the holders of a majority of the stock
present or represented at the meeting, although less than a quorum, or by any
officer entitled to preside or to act as Clerk of such meeting, if no
stockholder is present or represented. It shall not be necessary to notify any
stockholder of any adjournment. Any business which could have been transacted
at any meeting of the stockholders as originally called may be transacted at any
adjournment thereof.

     7.   Voting and Proxies.  Each stockholder shall have one vote for each
          ------------------
share of stock entitled to vote held by him of record according to the records
of the corporation, and a proportionate vote for a fractional share so held by
him, unless otherwise provided by the Articles of Organization. Stockholders
may vote either in person or by written proxy dated not more than six (6) months
before the meeting named therein; provided, that a proxy coupled with an
interest sufficient in law to support an irrevocable power, including, without
limitation, an interest in the shares or in the corporation generally, may be
made irrevocable if it so provides, need not specify the meeting to which it
relates, and shall be valid and enforceable until the interest terminates, or
for such shorter period as may be specified in the proxy. Proxies shall be
filed with the Clerk of the meeting or of any adjournment thereof before being
voted. Except as otherwise stated therein, proxies shall entitle the persons
named therein to vote at any adjournment of such meeting but shall not be valid
after final adjournment of such meeting. A proxy with respect to stock held in
the name of two or more persons shall be valid if executed by one of them
unless, at or prior to exercise of the proxy, the corporation receives a
specific written notice to the contrary from any one of them. A proxy purported
to be executed by or on behalf of a stockholder shall be deemed valid unless
challenged at or prior to its exercise.

     8.   Action at Meeting.  When a quorum is present, the holders of a
          -----------------
majority of the stock present or represented and voting on a matter (or if there
are two or more classes of stock entitled to vote as separate classes, then in
the case of each such class, the holders of a majority of the stock of that
class present or represented and voting on a matter), except where a larger vote
is required by law, by the Articles of Organization or by these By-laws, shall
decide any matter to be voted on by the stockholders. Any election by
stockholders shall be determined by a plurality of the votes cast by the
stockholders entitled to vote at the election. No ballot shall be required for
such election unless requested by a stockholder present or represented at the
meeting and entitled to vote in the election. The corporation shall not
directly or indirectly vote any shares of its stock other than shares held
directly or indirectly by it in a fiduciary capacity.

     9.   Inspectors of Election.  The Board of Directors, in advance of any
          ----------------------
meeting of stockholders, may appoint one or more inspectors to act at the
meeting or any adjournment thereof. If inspectors are not so appointed, the
person presiding at the meeting may, and on the

                                       2
<PAGE>

request of any stockholder entitled to vote thereat shall, appoint one or more
inspectors. If one or more inspectors are not so appointed, then the presiding
officer shall act as the inspector of the election. In case any person appointed
fails to appear or act, the vacancy may be filled by appointment made by the
Board in advance of the meeting or at the meeting by the person presiding
thereat. Each inspector, before entering upon the discharge of his duties, shall
take and sign an oath faithfully to execute the duties of inspector at such
meeting with strict impartiality and according to the best of his ability. No
director or officer of the corporation shall be eligible to act as an inspector
of an election of directors of the corporation.

          The inspectors shall determine the number of shares outstanding and
the voting power of each, the shares represented at the meeting, the existence
of a quorum, the validity and effect of proxies, and shall receive votes,
ballots or consents, hear and determine all challenges and questions arising in
connection with the right to vote, count and tabulate all votes, ballots or
consents, determine the result, and do such acts as are proper to conduct the
election or vote with fairness to all stockholders. On request of the person
presiding at the meeting or any stockholder entitled to vote thereat, the
inspectors shall make a report in writing of any challenge, question or matter
determined by them and execute a certificate of any fact found by them.

     10.  Action Without Meeting.  Any action to be taken by stockholders may be
          ----------------------
taken without a meeting if all stockholders entitled to vote on the matter
consent to the action by a writing filed with the records of the meetings of
stockholders.  Such consent shall be treated for all purposes as a vote at a
meeting.

                                  ARTICLE II

                                   DIRECTORS
                                   ---------


     1.   Powers.  The business of the corporation shall be managed by a Board
          ------
of Directors who may exercise all the powers of the corporation except as
otherwise provided by law, by the Articles of Organization or by these By-laws.
In the event of a vacancy in the Board of Directors, the remaining Directors,
except as otherwise provided by law, may exercise the powers of the full Board
until the vacancy is filled.

     2.   Election.  A Board of Directors consisting of seven (7) persons shall
          --------
be elected by the stockholders at the annual meeting or any special meeting in
lieu thereof.

     3.   Vacancies.  If the office of any Director becomes vacant by reason of
          ---------
death, resignation, retirement, disqualification, removal from office, or
otherwise, including by enlargement of the Board of Directors, the Board of
Directors or remaining Directors if less than a quorum may, by majority vote,
choose a successor or successors, who shall hold office for the unexpired term
in respect of which such vacancy occurred and until his successor be chosen and
qualified, or until his earlier death, resignation or removal.

                                       3
<PAGE>

     4.   Enlargement of the Board.  The number of the Board of Directors may be
          ------------------------
increased at any meeting of the stockholders or by a vote of the Directors then
in office.

     5.   Tenure.  The Directors shall be classified with respect to the time
          ------
for which they shall severally hold office by dividing them into three classes,
each consisting of one-third, or as equal in number as possible, of the whole
number of the Board of Directors, and all Directors shall hold office until
their successors are chosen and qualified, or until their earlier death,
resignation, or removal. At the first meeting held for election of the Board of
Directors following adoption of these By-laws, Directors of the first class
("Class I Directors") shall be elected for a term of one year; Directors of the
second class ("Class II Directors") shall be elected for a term of two years;
Directors of the third class ("Class III Directors") shall be elected for a term
of three years; and at each annual election thereafter, successors to the class
of Directors whose terms shall expire that year shall be elected to hold office
for a term of three years, so that the term of office of one class of Directors
shall expire in each year. Any Director may resign by delivering his written
resignation to the corporation at its principal office or to the President,
Clerk or Secretary, except that no Director shall resign by delivering such
resignation to himself. Such resignation shall be effective upon receipt unless
it is specified to be effective at some other time or upon the happening of some
other event.

     6.   Removal.  A Director may be removed from office for cause by vote of a
          -------
majority of the stock outstanding and entitled to vote in the election of
Directors, provided that the Directors of a class elected by a particular class
of stockholders may be removed only by the vote of the holders of a majority of
the shares of such class. A Director may be removed for cause only after
reasonable notice and opportunity to be heard before the body proposing to
remove him.

     7.   Meetings.  Regular meetings of the Directors may be held without call
          --------
or notice at such places, within or without Massachusetts, and at such times as
the Directors may from time to time determine, provided that any Director who is
absent when such determination is made shall be given notice of the
determination. A regular meeting of the Directors may be held without a call or
notice at the same place as the annual meeting of stockholders or the special
meeting held in lieu thereof, following such meeting of stockholders.

          Special meetings of the Directors may be held at any time and place,
within or without Massachusetts, designated in a call by the President,
Treasurer or two or more Directors.

     8.   Notice of Special Meetings.  Notice of all special meetings of the
          --------------------------
Directors shall be given to each Director by the Secretary, or if there be no
Secretary by the Clerk or Assistant Clerk, or in case of the death, absence,
incapacity or refusal of such persons, by the officer or one of the Directors
calling the meeting. Notice shall be given to each Director in person or by
telephone or by telegram sent to his business or home address at least forty-
eight (48) hours in advance of the meeting, or by written notice mailed to his
business or home address at least seventy-two (72) hours in advance of the
meeting. Notice need not be given to any Director if a written waiver of notice,
executed by him before or after the meeting, is filed with the records of the
meeting, or to any Director who attends the meeting without protesting prior
thereto or at its

                                       4
<PAGE>

commencement the lack of notice to him. A notice or waiver of notice of a
Directors' meeting need not specify the purposes of the meeting.

     9.   Quorum.  At any meeting of the Directors, a majority of the Directors
          ------
then in office shall constitute a quorum. In the event that one or more
Directors shall be disqualified to vote at any meeting, then the required quorum
shall be reduced by one for each such Director so disqualified; provided,
however, that in no case shall less than one-third (1/3) of the total number of
Directors constitute a quorum. Less than a quorum may adjourn any meeting from
time to time without further notice.

     10.  Action at Meeting.  At any meeting of the Directors at which a quorum
          -----------------
is present, the vote of a majority of those present, unless a different vote is
specified by law, by the Articles of Organization or by these By-laws, shall be
sufficient to take any action.

     11.  Meeting by Conference.  Members of the Board or any committee
          ---------------------
designated thereby may participate in a meeting of such Board or committee by
means of a conference telephone or similar communications equipment by means of
which all persons participating in the meeting can hear each other at the same
time and participation by such means shall constitute presence in person at a
meeting.

     12.  Action by Consent.  Any action by the Directors may be taken without a
          -----------------
meeting if a written consent thereto is signed by all the Directors and filed
with the records of the meetings of Directors. Such consent shall be treated
for all purposes as a vote at a meeting.

     13.  Committees.  The Directors may, by vote of a majority of the Directors
          ----------
then in office, elect from their number an executive committee or other
committees and may by like vote delegate thereto some or all of their powers
except those which by law, the Articles of Organization or these By-laws, they
are prohibited from delegating. Each committee is to consist of two or more
Directors. The Board may designate one or more Directors as alternate members of
any committee, who may replace any absent or disqualified member at any meeting
of the committee. In the absence or disqualification of a member of a committee,
the member or members thereof present at any meeting and not disqualified from
voting, whether or not he or they constitute a quorum, may unanimously appoint
another member of the Board of Directors to act at the meeting in the place of
any such absent or disqualified member. Each such committee shall keep minutes
and make such reports as the Board of Directors may from time to time request.
Except as the Directors may otherwise determine, any such committee may make
rules for the conduct of its business but, unless otherwise provided by the
Directors or in such rules, its business shall be conducted as nearly as may be
in the same manner as is provided by these By-laws for the Directors.

          ------
Organization or by these By-laws, the President, Treasurer and Clerk shall hold

stockholders or special meeting in lieu thereof and thereafter until their
successors are chosen and qualified; and all other officers shall hold office

                                  ARTICLE IV

                                 CAPITAL STOCK
                                 -------------


     1.   Certificates of Stock.  Each stockholder shall be entitled to a
          ---------------------
certificate of the capital stock of the corporation in such form as may be
prescribed from time to time by the Directors. The certificate shall be signed
by the President or a Vice President, and by the Treasurer or an Assistant
Treasurer, but when a certificate is countersigned by a transfer agent or a
registrar, other than a Director, officer or employee of the corporation, such
signatures may be facsimiles. In case any officer who has signed or whose
facsimile signature has been placed on such certificate shall have ceased to be
such officer before such certificate is issued, it may be issued by the
corporation with the same effect as if he were such officer at the time of its
issue.

          Every certificate for shares of stock which are subject to any
restriction on transfer pursuant to the Articles of Organization, the By-laws or
any agreement to which the corporation is a party, shall have conspicuously
noted on the face or back of the certificate either the full text of the
restriction or a statement of the existence of such restrictions and a statement
that the corporation will furnish a copy thereof to the holder of such
certificate upon written request and without charge. Every certificate issued
when the corporation is authorized to issue more than one class or series of
stock shall set forth on its face or back either the full text of the
preferences, voting powers, qualifications and special and relative rights of
the shares of each class and series authorized to be issued, or a statement of
the existence of such preferences, powers, qualifications and rights, and a
statement that the corporation will furnish a copy thereof to the holder of such
certificate upon written request and without charge.

     2.   Transfers.  Subject to the restrictions, if any, stated or noted on
          ---------
the stock certificates, shares of stock may be transferred on the books of the
corporation by the surrender to the corporation or its transfer agent of the
certificate therefor, properly endorsed, or accompanied by a written assignment
and power of attorney properly executed, with necessary transfer stamps affixed
and with such proof of the authenticity of signature as the corporation or its
transfer agent may reasonably require. Except as may be otherwise required by
law, by the

                                       8
<PAGE>

Articles of Organization or by these By-laws, the corporation shall be entitled
to treat the record holder of stock as shown on its books as the owner of such
stock for all purposes, including the payment of dividends and the right to vote
with respect thereto, regardless of any transfer, pledge or other disposition of
such stock, until the shares have been transferred on the books of the
corporation in accordance with the requirements of these By-laws. It shall be
the duty of each stockholder to notify the corporation of his post office
address and of his taxpayer identification number.

     3.   Record Date.  The Directors may fix in advance a time not more than
          -----------
sixty (60) days preceding the date of any meeting of stockholders, or the date
for the payment of any dividend, or the making of any distribution to
stockholders, or the last day on which the consent or dissent of stockholders
may be effectively expressed for any purpose, as the record date for determining
the stockholders having the right to notice of and to vote at such meeting, and
any adjournment thereof, or the right to receive such dividend or distribution,
or the right to give such consent or dissent. In such case only stockholders of
record on such record date shall have such right, notwithstanding any transfer
of stock on the books of the corporation after the record date. Without fixing
such record date, the Directors may for any of such purposes close the transfer
books for all or any part of such period. If no record date is fixed, the record
date for determining stockholders entitled to notice of or to vote at a meeting
of stockholders shall be at the close of business on the day before the day on
which notice is given, or, if notice is waived, at the close of business on the
day before the day on which the meeting is held. The record date for determining
stockholders for any other purpose shall be at the close of business on the day
on which the Board of Directors adopts the resolution relating to such purpose.
A determination of stockholders of record entitled to notice of or to vote at a
meeting of stockholders shall apply to any adjournment of the meeting; provided,
however, that the Board of Directors may fix a new record date for the adjourned
meeting.

     4.   Replacement of Certificates.  In case of the alleged loss or
          ---------------------------
destruction or the mutilation of a certificate of stock, a duplicate certificate
may be issued in place thereof upon such terms as the Directors may prescribe,
including the presentation of reasonable evidence of such loss, destruction or
mutilation, and the giving of such indemnity as the Directors may require, for
the protection of the corporation or any transfer agent or registrar.

     5.   Issue of Capital Stock.  Unless otherwise voted by the stockholders,
          ----------------------
the whole or any part of any unissued balance of the authorized capital stock of
the corporation, or the whole or any part of the capital stock of the
corporation held in its treasury, may be issued or disposed of by vote of the
Directors in such manner, for such consideration, and on such terms as the
Directors may determine.

          ------------------------
bonds, notes and other obligations authorized to be executed by an officer of

except as the Directors may generally or in particular cases otherwise
determine.

     4.   Voting of Securities.  Except as the Directors may otherwise
          --------------------
designate, the President or Treasurer may waive notice of and act as, or appoint
any person or persons to act as, proxy or attorney-in-fact for this corporation
(with or without power of substitution) at any meeting of stockholders or
shareholders of any corporation or organization, the securities of which may be
held by the corporation (including securities of the corporation held directly
or indirectly by it in a fiduciary capacity).

     5.   Corporate Records.  The original or attested copies of the Articles of
          -----------------
Organization, By-laws and records of all meetings of the incorporators and
stockholders, and the stock and transfer records which shall contain the names
of all stockholders and the record address and the amount of stock held by each
shall be kept in Massachusetts at the principal office of the corporation or at
an office of its transfer agent or of the Clerk. Said copies and records need
not all be kept in the same office. They shall be available at all reasonable
times to the inspection of any stockholder for any proper purpose, but not to
secure a list of stockholders for the purpose of selling said list or copies
thereof, or of using the same for a purpose other than in the interest of the
applicant, as a stockholder, relative to the affairs of the corporation.

     6.   Evidence of Authority.  A certificate by the Clerk or Secretary or
          ---------------------
Assistant Clerk or Assistant Secretary, or a temporary Clerk or temporary
Secretary, as to any action taken by the stockholders, Directors, Executive
Committee or any officer or representative of the corporation shall, as to all
persons who rely thereon in good faith, be conclusive evidence of such action.

     7.   Articles of Organization.  All references in these By-laws to the
          ------------------------
Articles of Organization shall be deemed to refer to the Articles of
Organization of the corporation as amended and in effect from time to time.

     8.   Transactions With Interested Parties.  In the absence of fraud, no
          ------------------------------------
contract or other transaction between this corporation and any other corporation
or any firm, association, partnership or person shall be affected or invalidated
by the fact that any Director or officer of this corporation is pecuniarily or
otherwise interested in, or is a Director, member or officer of,

                                       10
<PAGE>

such other corporation or of such firm, association or partnership, or is a
party to or is pecuniarily or otherwise interested in such contract or other
transaction, or is in any way connected with any person or persons, firm,
association, partnership or corporation pecuniarily or otherwise interested
therein; provided that the fact that he individually or as a Director, member or
officer of such corporation, firm, association or partnership is such a party or
is so interested shall be disclosed to or shall have been known by the Board of
Directors or a majority of such members thereof as shall be present at a meeting
of the Board of Directors at which action upon any such contract or transaction
shall be taken. Any Director may be counted in determining the existence of a
quorum and may vote at any meeting of the Board of Directors of this corporation
for the purpose of authorizing any such contract or transaction with like force
and effect as if he were not so interested, or were not a Director, member or
officer of such other corporation, firm, association or partnership; provided
that any vote with respect to such contract or transaction must be adopted by a
majority of the Directors then in office who have no interest in such contract
or transaction.

     9.   Indemnification.  Each person at any time a Director, officer,
          ---------------
employee or agent of the corporation and any person who serves at its request as
a director, officer, employee or other agent of another organization, or who
serves at its request in any capacity with respect to any employee benefit plan,
including each former Director, officer, employee or agent who was before, on or
after the date of the adoption of this By-law shall, to the extent permitted by
law and without prejudice to any other rights he might have, be entitled to be
reimbursed by the corporation for, and indemnified by the corporation against,
all judgments, fines, penalties, costs and expenses reasonably incurred by him
in connection with or arising out of any claims made, or any action, suit or
proceeding threatened or brought against him or in which he may be involved as a
party or otherwise to which he may be or become subject by reason of any action
alleged to have been taken or omitted by him as a Director, officer, employee or
agent, or in any capacity with respect to any employee benefit plan, whether or
not he continues to be a Director, officer, employee, or agent, or to serve in
any capacity with respect to any employee benefit plan, at the time of incurring
such costs and expenses, including amounts paid or incurred by him in connection
with reasonable settlements (other than amounts paid to the corporation itself)
of any claim, action, suit or proceeding. Any rights to reimbursement and
indemnification granted under this section to any such Director, officer,
employee or agent shall extend to his heirs, executors, and administrators. No
such reimbursement or indemnification shall be provided for any person with
respect to any matter as to which he shall have been adjudicated in any
proceeding not to have acted in good faith in the reasonable belief that his
action was in the best interests of the corporation, or to the extent that such
matter relates to service with respect to an employee benefit plan, in the best
interests of the participants or beneficiaries of such employee benefit plan.
Reimbursement or indemnification hereunder may, in the discretion of the Board
of Directors, include payments by the corporation of costs and expenses incurred
in defending a civil or criminal action or proceeding in advance of the final
disposition of such action or proceeding upon receipt of an undertaking by the
person indemnified to repay such payment if he shall be adjudicated to be not
entitled to indemnification hereunder, which undertaking may be accepted without
reference to the financial ability of such person to make repayment. Nothing
herein contained is intended to, or shall, prevent a settlement by the
corporation prior to final adjudication of any claim, including claims for
reimbursement or indemnification under this By-

                                       11
<PAGE>

law, against the corporation when such settlement appears to be in the interest
of the corporation. Each such person shall, by reason of his continuing such
service or accepting such election or employment, have the right to be
reimbursed and indemnified by the corporation, as above set forth with the same
force and effect as if the corporation, to induce him to continue so to serve or
to accept such election or employment, specifically agreed in writing to
reimburse and indemnify him in accordance with the foregoing provisions of this
section. No Director or officer of the corporation shall be liable to anyone for
making any determination as to the existence or absence of liability of the
corporation hereunder or for making or refusing to make any payment hereunder in
reliance upon advice of counsel.

     10.  Amendments.  These By-laws may be amended or repealed and new by-laws
          ----------
adopted either (a) by the stockholders at any regular or special meeting of the
stockholders by the affirmative vote of the holders of at least seventy-five
percent (75%) in interest of the capital stock then outstanding and then
entitled to vote, provided that notice of the proposed amendment or repeal and
adoption stating the change or the substance thereof shall have been given in
the notice of such meeting or in the waiver of notice with respect to such
meeting, or (b) by vote of a majority of the Board of Directors then in office,
provided that (i) the Board of Directors may not amend or repeal any provision
of these By-laws which by law, by the Articles of Organization or by these
By-laws requires action by the stockholders, (ii) not later than the time of
giving notice of the meeting of stockholders next following the amendment or
repeal of these By-laws and adoption of new by-laws by the Board of Directors,
notice thereof stating the change or the substance of such change shall be given
to all stockholders entitled to vote on amending these By-laws, and (iii) any
amendment or repeal of these By-laws by the Board of Directors and any by-law
adopted by the Board of Directors may be amended or repealed by the
stockholders.

     11.  Severability. Any determination that any provision of these By-laws is
          ------------
for any reason inapplicable, illegal or ineffective shall not affect or
invalidate any other provision of these By-laws.

     12.  Pronouns. All pronouns used in these By-laws shall be deemed to refer
          --------
to the masculine, feminine or neuter, singular or plural, as the identify of the
person or persons may require.

17.  FORCE MAJEURE


Neither party shall be deemed to be in default of any provision of this
Agreement for any failure in performance resulting from acts or events beyond
its reasonable control, including acts of God.  Each party will use its best
efforts to anticipate such failures and to devise means to eliminate or minimize
them.  But if a failure continues for more than sixty (60) days, either party

                               SUPPORT SERVICES


1.  SUPPORT LEVELS AND INTERFACE DEFINITIONS


These provisions are to be used by Newbridge and Vendor personnel for the
support level that must be provided for any problem or issue before it can be
escalated to the next defined level.

The activities identified are the minimum required, and may be supplemented by
further actions during the course of the problem investigation in order to
expedite a resolution.  First and Second-Level Support will be provided by
Newbridge for Newbridge End Users who have purchased the products from Newbridge
or its business partners.  Third-Level Support will be provided by Vendor to
Newbridge and directly to Newbridge End Users as deemed necessary by Newbridge.

    1.1  First-Level NTAC (Front Office) Support.  Newbridge will provide front
    ---- ---------------------------------------
office TAC support and basic help desk functions to the End User. Typically this
will include initial call handling, call logging, assignment of call priority
(Emergency, High, Medium and Low) and queue placement . This will be performed
by either the Newbridge Technical Assistance Centre (NTAC) or the Newbridge
Distributor/Service Agent. The NTAC is the focal point for all operational
support activities and is the contact point between the Customer and Newbridge.
NTAC is staffed and operational seven days a week, twenty-four hours a day,
365 days per year for first-level front office support.

    1.2  First-Level NTAC (Back Office) Support.  Newbridge will provide initial
    ---- --------------------------------------
product problem diagnostic services for identifying problems and generic
application faults, analysis, and where possible, problem resolution.

    1.3  Second-Level Support.  Newbridge will provide detailed product problem
    ---- --------------------
analysis, as well as any problem duplication in the NTAC laboratory. Second-
Level Support will provide more detailed problem diagnostic services for
identifying complex problems and application faults that cannot be resolved by
First-Level Back Office Support. Second-Level Support will be responsible for

Statement of Work and/or the Agreement, or (b) let Millitech continue its
attempts to correct the Deficiencies for a time specified by Newbridge.  If at
the end of that specified time Millitech has not corrected the Deficiencies,
Newbridge may terminate the Agreement.

For the purposes of this Statement of Work:

     . "Engineering Prototype" shall mean an OTU which must be functional with
     all electrical and mechanical interfaces pursuant to the Technical
     Specification. The units are intended for Research and Development use
     primarily for integration, functional testing and limited characterization.
     Although there may be non-conformance with the Technical Specification, the
     Engineering Prototypes must be usable and Millitech must disclose known
     problems to Newbridge in the design verification report.

     . "Pre-Production Prototype" shall mean an OTU which is compliant to the
     form, fit and function of the Technical Specification of the OTU. The units
     are intended for Field Trial use to enable system testing and

- -- Hubs will be configured in Motorola's desired polarization configuration, the
   polarization will be identified when Motorola "issues releases" to Millitech.
- -- When "releases are issued" to Millitech new line items will be added to this
   Purchase Order and the quantities will be reduced on line item 1 and 2.
- -- Warranty is [***] from the date of shipment from Millitech for all items
   shipped against this Purchase Order.
- -- Motorola will provide Millitech with a delivery forecast (forecast will be
   for [***] Hubs and [***] CPE's spread out by month until 12-31-01) with the
   release of this Purchase Order and it will be updated on a monthly basis.
- -- Motorola will finalize hand delivery requirements 16 weeks prior to delivery.
   This firm release will identify the quantities and delivery dates as well as
   the part numbers and/or technical requirements for the hardware. Once a
   month, Motorola will "issue revised releases" to reflect the new forecast
   (hard deliveries).

NOTE 2: -- Millitech will execute advance procurement and planning to meet our
           delivery forecast. With this, Millitech may commit to procure up to
           20 weeks of material (per our schedule). In the event that Motorola's
           sales do not develop as planned for the LMDS Program, Motorola will
           be liable to Millitech for material procured by Millitech within the
           20-week window. If hardware has not been assembled, Motorola's
           maximum liability will not exceed [***] per CPE and [***] per Hub.
           Motorola will be 100% responsible for all hard commits within the 16-
           week delivery window and has the option to change the quantities in
           weeks 12-16 by 33% with no charge.
        -- In the event that Motorola's LMDS sales do not develop as planned,
           Motorola will be liable to Millitech for 20-weeks of production as
           stated above only. The unit prices as shown on this P.O. will remain
           the same (Hubs [***] each and [***] each for the CPE's) in the event
           that sales are not as high as projected.
        -- Program reviews will be held monthly between Millitech and Motorola,
           we will rotate facilities.

1.  DEFINITIONS.  As used throughout this contract, including, if any,
provisions incorporated by reference the following terms shall have the meaning
set forth below:

(a)  The term "Seller" means the person, firm or corporation executing this
     contract with Motorola and who will furnish the work or services provided
     for herein.

(b)  The term "Motorola" unless otherwise defined shall mean the Space and
     Systems Technology Group of Motorola, Inc.

(c)  The term "prime contract" means the contract with the customer.

(d)  The word "contract" unless otherwise modified shall mean the agreement.

(e)  Except as otherwise provided in this contract, the term "subcontract"
     includes purchase orders placed by the Seller under this contract and all
     references to "supplies" shall include "services", if the contract wholly
     or in party provides for the furnishing of services.

2.  ORDER OF PRECEDENCE.  The rights and obligations of the parties to this
contract shall be subject to and governed by the Statement of Work, these Terms
and Conditions, and any proposals, specifications or other documents or
provisions which are made a part of this contract by reference or otherwise. To
the extent of any inconsistency between (i) the Statement of Work and these
Terms and Conditions and (ii) proposals, specifications or other documents or
provisions which are made a part of this contract by reference or otherwise, the
Statement of Work and these Terms and Conditions shall control. To the extent of
any inconsistency between (i) the Statement of Work and (ii) these Terms and
Conditions, the Statement of Work shall control.



3.   CHANGES.

(a)  Motorola may at any time, without notice to the sureties of any, through
     written directions, require reduction or addition or work, issue additional
     restrictions, or extend the performance of the work all within the general
     scope of this contract.

(b)  If any such direction causes an increase or decrease in the cost of, or the
     time required or the performance of, this contract, or otherwise affects
     any other provision of this contract, whether changes or not changed by any
     such direction, an equitable adjustment shall be made (1) in the contract
     price or time of performance or both, and (2) in such other provisions of
     the contract as may be so affected, and the contract shall be modified in
     writing accordingly.

(c)  Any claim by the Seller for adjustment under this article must be asserted
     in writing within 30 days from the date of receipt by the Seller of the
     notification of change provided, however, that Motorola, if it decides that
     the facts justify such action, may receive and act upon any such claim
     asserted at any time prior to final payment

<PAGE>

     under this contract. Nothing in this article shall excuse the Seller from
     proceeding with the contract as changed. Failure to agree to any adjustment
     shall be a dispute concerning a question of fact within the meaning of the
     article of this contract entitled "Disputes".

(d)  Where the full cost, or substantially the full cost, of property made
     obsolete or excess as a result of a change is included in the Seller's
     claim for adjustment, Motorola shall have the right to prescribe the manner
     of disposition of such property.

(e)  Motorola engineering and technical personnel may from time to time render
     assistance or give technical advice to, or discuss or effect and exchange
     of information with the Seller's personnel concerning the work hereunder.
     Such actions shall not be deemed to be a change under this article and
     shall not vest Seller with authority to change the work hereunder.  In the
     event Seller receives an instruction, order or advice that he deems to be a
     change from anyone other than Motorola's Supply Management Department, he
     shall immediately advise Motorola's Purchasing Department of that
     instruction, order or advice, Seller shall not be entitled to any
     adjustment of the contract price, delivery schedule or other contract
     provisions because of actions taken by the Seller pursuant to said
     instruction, order or advice unless and until and only to the extent such
     instruction, order or advice shall be included in a Purchase Order Revision
     or Change Order or Supplemental Agreement to this contract issued by
     Motorola's Supply Management Department, in writing, whenever any change
     received from any representative of Motorola affects specifications,
     quantities, delivery, prices or other conditions of this contract.

(f)  The Seller shall not make any changes in the work or end items (including
     assemblies, subassemblies, parts and components thereof) which do not
     conform to the requirements of this contract without the prior written
     consent of Motorola.  Motorola may present as a procedure for the reporting
     and approval of changes initiated by the Seller.

4.  NOTICES.  All notices required or permitted to be sent by either party
hereto shall be deemed sufficiently given if sent by prepaid certified mail to
the address shown on the first page of this contract for each party and to the
attention of the individual who executes this contract on behalf of the party to
whom the notice is sent.  All notices shall be deemed given when they are sent
by certified mail and deposited in the mail addressed in the aforesaid manner.
Either party may designate, in writing, a different manner of address for
notices under this contract.

5.  INSURANCE AND INDEMNIFICATION.  In the event the Seller, its employees,
agent, subcontractors, or lower-tier subcontractors enter premises occupied by
or under the control of Motorola in the performance of this contract, the Seller
agrees that it will be responsible to Motorola for, and indemnify and hold
harmless Motorola, its officers and employees, from any loss, cost, damage,
expense or liability by reason of property damage or personal injury of
whatsoever kind or character arising out of, as a result of, or in connection
with such performance occasioned by the negligence or other fault, act or
<PAGE>

omission, of the Seller, its employees, agents, subcontractors, or lower-tier
subcontractors and the Seller agrees that it and its subcontractors will
maintain public liability and property damage insurance in reasonable limits
covering the obligations set forth above and will maintain Worker's Compensation
Insurance covering all employees performing this contract on premises occupied
or under the control of Motorola provided, however, that the Seller may maintain
a self-insurance program in lieu of Worker's Compensation Insurance if
authorized and qualified to do so pursuant to statutory authority.  Seller shall
provide certificates of such insurance upon request.

6.  INSPECTION.

(a)  All services and supplies (which term throughout this article includes the
     Seller without limitation raw material, components, intermediate assemblies
     and end products) may be subject to inspection and test by Motorola, to the
     extent practicable at all reasonable times and places including the period
     of manufacture and, in any event, prior to final acceptance.

(b)  In case any supplies or lots of supplies are defective in material or
     workmanship or otherwise not in conformity with the requirements of this
     contract, Motorola shall have the right either to reject them (with or
     without instructions as to their disposition) or to require their
     correction.  Supplies or lots of supplies which have been rejected or
     required to be corrected shall be removed or, if permitted or required by
     Motorola, corrected in place by and at the expense of the Seller promptly
     after notice, and shall not thereafter be tendered for acceptance unless
     the former rejection or requirement for correction is disclosed.  If the
     Seller fails to promptly remove such supplies or lots of supplies which are
     required to be removed or promptly to replace or correct such supplies or
     lots of supplies, Motorola (i) may, by contract or otherwise, replace or
     correct such supplies and charge to the Seller the cost occasioned to
     Motorola, or (ii) may terminate this contract for default as provide din
     the article of this contract entitled "Default".  Unless the Seller
     corrects or replaces such supplies within the delivery schedule, Motorola
     may require the delivery of such supplies at a reduction in price which is
     equitable under the circumstances.  Failure to agree to such reduction in
     price shall be a dispute concerning a question of fact within the meaning
     of the article of this contract entitled "Disputes."

(c)  If any inspection or test is made by Motorola on the premises of the Seller
     without additional charge shall provide all reasonable facilities and
     assistance for the safety and convenience of inspectors in the performance
     of their duties.  If the Motorola inspection or test is made at a point
     other than the premises of the Seller, it shall be at the expense of
     Motorola except as otherwise provided in this contract, provided that, in
     case of rejection, Motorola shall not be liable for any reduction in value
     of samples used in such inspection or test.  All inspections and tests
     shall be performed in such a manner as not to unduly delay the work.
     Motorola reserves the right to charge to the Seller any additional cost of
     inspection or test when supplies are not ready at the time such inspection
     or test is requested by the Seller or when reinspection or retest is
     necessitated
<PAGE>

     by a prior rejection. Acceptance or rejection of the supplies shall be made
     as promptly as practicable after delivery except as otherwise provided in
     this contract, but failure to inspect and accept or reject supplies shall
     neither relieve the Seller from responsibility for such supplies as are not
     in accordance with the contract requirements nor impose liability to
     Motorola therefore.

(d)  The inspection and test by Motorola of any supplies or lots thereof does
     not relieve the Seller from any responsibility regarding defects or other
     failures to meet the contract requirements which may be discovered prior to
     acceptance.  Unless otherwise provided in this contract, acceptance shall
     be conclusive except with respect to latent defects, fraud, such gross
     mistakes amounting to fraud, and the Seller's warranty obligations.

(e)  The Seller shall provide and maintain a quality and inspection system
     acceptable to Motorola covering the supplies hereunder.  Records of all
     inspection work by the Seller shall be kept complete and available to
     Motorola during the performance of this contract and for such longer
     periods as may be specified in this contract.

(f)  Seller hereby certifies that all supplies in the quantities so called for
     on the face of this contract will conform with all requirements, drawings,
     and related documents referenced by or in this contract. The required test
     and inspection reports resulting from compliance with this contract will be
     maintained on file and be made available for review by Motorola's
     representative, at any reasonable time.

7.  TITLE AND RISK OF LOSS.

(a)  Unless this contract specifically provides for earlier passage of title,
     title to supplies covered by this contract shall pass to Motorola upon
     final acceptance by Motorola or the Government, regardless of when Motorola
     takes physical possession.

(b)  Unless this contract specifically provides otherwise, the transportation of
     supplies to be delivered by Seller to Motorola shall be F.O.B. destination
     and all risk of loss of or damage to the supplies covered by this contract
     shall remain with the Seller until final acceptance by Motorola or receipt
     of the supplies by Motorola at the destination specified in this contract,
     whichever is later.

(c)  If the contract specifies the transportation of supplies to be delivered by
     Seller to Motorola as F.O.B. origin (i.e. Seller's facility), all risk or
     loss of or damage to the supplies covered by this contract shall remain
     with the Seller until Seller delivers the supplies to an authorized carrier
     for shipment to Motorola.

(d)  Notwithstanding (b) and (c) above, risk of loss of or damage to supplies
     which fail to conform to the requirements of this contract as to give a
     right or rejection shall remain with Seller until cure by Seller or final
     acceptance by Motorola, whichever is later, at which time (b) or (c) above
     shall apply.
<PAGE>

8.  PAYMENTS.

(a)  Payment of the contract price or any portion thereof for supplies delivered
     or services rendered shall not constitute acceptance.  The Seller shall be
     paid, upon admission of property certified invoices or vouchers, the prices
     stipulated herein for supplies delivered or services rendered less
     deductions, if any, as herein provided.

(b)  If more than one article of this contract authorizes the temporary
     withholding of amounts otherwise payable to the Seller for supplies
     delivered or services performed, the total of the amounts so withheld at
     any one time shall not exceed the greatest amount which may be withheld
     under any one such article at that time, provided that this limitation
     shall not apply to (i) withholdings pursuant to any article relating to
     wages or hours of employees; (ii) withholdings not specifically provided
     for by this contract, and (iii) the recovery of overpayments.

(c)  It is understood that the efficient use by Motorola of the supplies called
     for hereunder require that the data called for by this contract be
     delivered not later than the time or respective times herein specified.  If
     such data is not delivered at said time or times, Motorola may at its
     election, so long as such data remains undelivered, unless the delay in
     delivery thereof arises out of causes beyond the control and without the
     fault or negligence of the Seller within the meaning of the article hereof

15.  DEFAULT.

(a)  Motorola may, subject to the previsions of paragraph (c) below, by written
     Notice of Default to the Seller terminate the whole or any part of this

     the services within the time specified herein or any extension thereof; or
     (ii) if the Seller fails to perform any of the other provisions of this
     contract or so fails to make progress as to endanger performance of this
     contract in accordance with its terms, and if either of these two later
     circumstances does not cure such a failure within a period of 10 days, or

     other damages.  The Seller shall continue the performance of this contract
     to the extent not terminated under the provisions of this article.

(c)  Except with respect to defaults of subcontractors, the Seller shall not be

     failure to perform must be beyond the control and without the fault or
     negligence of the Seller.  If the failure to perform is caused by the
     default of a subcontractor and if such default arises out of causes beyond
     the control of both the Seller and subcontractor and without the fault or
     negligence of either of them, the Seller shall not be liable for any
<PAGE>

     information and contract rights (hereinafter call "manufacturing
     materials") as the Seller has specifically produced or specifically
     acquired for the performance of any part of this contract which has been
     terminated.  Seller shall protect and preserve property in possession of
     the Seller in which Motorola has an interest.  Payment for completed
     supplies delivered to and accepted by Motorola shall be at the contract
     price.  Payment for manufacturing materials delivered to and accepted by
     Motorola and for its protection and preservation of property shall be an
     amount agreed upon by the parties.  Failure to agree shall be a dispute
     concerning a question of fact within the meaning of the article of this
     contract entitled "Disputes."

(e)  If, after notice of termination of this contract under the provisions of
     paragraph (a) of this article, it is determined that the failure to perform
     is due to causes beyond the control and without the fault or negligence of
     the Seller or subcontractor pursuant to the provisions of paragraph(c) of
     this article, such Notice of Default shall be deemed to have been issued
     pursuant to the articles of this contract entitled "Termination" and the
     rights and obligations of the parties hereto shall in such an event be
     governed by that article.

     and for any further period to which the parties may agree.  Any such order
     shall be specifically identified as a Stop Work Order issued pursuant to

     of the contract, and (ii) the Seller asserts a claim at any time prior to
     final payment under this contract.  Failure to agree to any adjustment

     terminated for reasons other than default, reasonable costs resulting from
     the Stop Work Order shall be allowed in arriving at the termination
     settlement.

(d)  If a Stop Work Order is not canceled and the work covered by such order is
     terminated for default, the reasonable costs resulting from the Stop Work
     Order shall be allowed by equitable adjustment or otherwise.

     THIS LEASE, made this 16th day of January, 1990 by and between EDWARD J.
O'LEARY - RAYMOND M. VINCUNAS PARTNERSHIP (hereinafter referred to as
"Landlord") and MILLITECH CORPORATION, a corporation existing under the laws of
the Commonwealth of Massachusetts (hereinafter referred to as "Tenant").

                                   WITNESSETH

     Landlord, for and in consideration of the payment of the rent and the
performance of the covenants and agreements by Tenant herein contained, does
hereby lease to Tenant, and Tenant hereby lease from Landlord, the following
described premises:

     A free-standing building ("Building 1") of 31,395 square feet of floor
space located on a certain parcel of land on the south side of East Site Access
Road, Deerfield Industrial Park, South Deerfield, Massachusetts, known as Lot 9
containing approximately 3.096 acres ("Parcel 1").  The land is more
particularly described in Exhibit A attached hereto and made a part hereof.  A
second free-standing building ("Building 2") consisting of 7200 square feet of
one-story floor space and a 2-story building addition of 24,000 square feet of
floor space located on a certain parcel of land located on the south side of
East Site Access Road, Deerfield Industrial Park, South Deerfield,
Massachusetts, known as Lot 8 containing approximately two (2) acres ("Parcel
2").  Parcel 2 is more particularly described in Exhibit B attached hereto and
made a part hereof.  The 24,000 square foot addition to Building 2 is to be
constructed for use by the Tenant in accordance with the plans and
specifications described in Exhibit C which plans and specifications were
supplied to Landlord and Tenant and are incorporated herein by reference.
Building 1 and Building 2 and Parcels 1 and 2 are hereafter collectively
referred to as the "Premises" or "Leased Premises."

ARTICLE 1.    TERM
              ----

     a. The initial term of this Lease shall be for ten (10) years commencing on
the Commencement Date as hereinafter defined and expiring without further notice
or act on the tenth anniversary of the Commencement Date, as defined herein,
said period being hereinafter referred to as the "Initial Term."

     b. Provided that the Tenant has provided notice thereof one hundred eighty
(180) days prior to the expiration of the immediately preceding lease term, the
Tenant shall have the right to extend the term of this Lease for an additional
five (5) year term upon and subject to the provisions of this Lease.
<PAGE>

     ARTICLE 2. COMMENCEMENT DATE
                -----------------

     The Commencement Date shall be the date upon which the addition to Building
2 is substantially completed in accordance with the plans and specifications
attached hereto as Exhibit C as indicated by the proper municipal authorities of
a Certificate of Occupancy for the addition to Building 2.

     Promptly after the date hereof, Landlord will begin and prosecute the
construction of the Building 2 Addition in accordance with Exhibit C which
construction shall hereinafter be referred to as the "Improvements."  In order
to determine that the Improvements are being built in accordance with the plans
and specifications, the Tenant and its representatives, shall have access to the
Improvements at all reasonable times during the construction thereof for the
purpose of making inspections of the work.

     The Improvements shall be substantially completed and premises made
available to Tenant not later than June 30, 1990.  Provided however, if the
construction of the Improvements shall be delayed by causes beyond the
reasonable control of Landlord, such as, but not limited to, strikes, inclement
weather making construction not feasible, scarcity of materials, acts of God,
war and governmental restrictions, the Commencement Date shall be adjusted
accordingly and rental payments shall abate until delivery of possession occurs.
Landlord shall advise Tenant in writing of the Commencement Date not less than
ten (10) days prior thereto and immediately after the Commencement Date, the
Landlord and Tenant will enter into a written memorandum of the date of
commencement.  Any work provided to be done under the plans and specifications
which shall not have been completed at the Commencement Date, shall be promptly
completed by Landlord and if not completed within thirty (30) days after the
delivery of possession, the Tenant may after fifteen (15) days written notice to
the Landlord complete the same and deduct the cost thereof from the rent for the
next ensuing month or months.

     ARTICLE 3.  RENT
                 ----

     Tenant in consideration of the Lease, covenants and agrees to pay to
Landlord, as minimum annual rent (hereinafter referred to as "Base Rent") for
said Premises the following:

     (i) for the first through fifth years of the initial term, the sum of Three
Hundred Thirty-Eight Thousand Six Hundred Seventy-Three and 73/100 Dollars
($338,673.74) payable in equal monthly installments of Twenty-Eight Thousand Two
Hundred Twenty-Two and 81/100 Dollars ($28,222.81);

     (ii) during the sixth through tenth years of the initial term, at an annual
rate equal to the Base Rent of the first though fifth years of the initial term
increased by the greater of a) 20% or b) the percentage increase in the Consumer
Price Index during the first through fifth years of the initial term;
<PAGE>

     (iii)  during the five year optional extension period, at an annual rate
which is the greater of the Base Rent during the sixth through tenth years of
the initial term increased by the greater of a) Twenty Percent (20%); or b) the
percentage increase in the Consumer Price Index during the sixth through tenth
years of the initial term.

     Rent shall be paid in advance on the first day of each and every calendar
month during the term hereof.  If the Commencement Date is other than the first
day of the calendar month, rent for the portion of the calendar month at the
beginning of the term and at the end of the term shall be apportioned.  Said
payment shall be made in such manner and at such place or places as Landlord may
direct and until further notice said rental payments shall be made to the
Landlord; c/o Development Associates, 630 Silver Street, Unit 3C, P.O. Box 528,
Agawam, Massachusetts   01001-0528.

     The Base Rent for the Initial Term has been established, in part, based
upon the cost to the Landlord of financing improvements to Building 1,
construction of Building 2, and construction of the addition to Building 2 with
a loan from Shawmut Bank N.A. at an initial rate of interest of eleven and  1/4
percent (11.25%) per annum for a twenty-five (25) year loan term.  The rate of
interest on the loan is subject to changes monthly.  In the event that the
interest rate on the Landlord's loan increases in any year, the Tenant shall pay
as Additional Rent any increases in the Landlord's debt service cost by
reimbursing the Landlord annually for interest in excess of eleven and  1/4
percent (11.25%) per annum (the "Excess Interest") paid to a lending institution
to service the above mentioned debt.  The Tenant's responsibility to pay Excess
Interest shall be limited in any one year to a three percent (3%) increase in
said interest rate, it being the intention of the parties however that said
increases by cumulative, using the highest interest rate paid any prior year as
a base for calculating the three percent (3%) interest rate increase ceiling in
the succeeding year.

     Any payment of Rent shall be considered overdue and assessed an interest
fee equal to one percent (1%) of the current monthly Base Rent unless said
payment is a) personally delivered to Landlord's place of business not more than
fifteen (15) calendar days after date due, or b) sent to Landlord postmarked not
more than ten (10) days after date due.  In the event that an interest fee is
incurred, Landlord will promptly notify Tenant in writing of such event and
specify the amount of interest fee assessed.  Tenant acknowledges that any such
amounts are due immediately and shall pay the full amount of interest fee to
Landlord within ten (10) days of receipt of said written notice.

     It is the intention of the Landlord and Tenant that the rents and other
charges due the Landlord are "net" to the Landlord and that except for the
Landlord's obligations to pay for certain items of repair and/or replacement
specifically set forth in this Lease that the Tenant shall pay for all services,
utilities, repairs, insurances, taxes, and all other operating expenses of the
Premises whether or not specifically enumerated in this Lease.

     ARTICLE 4.  USE OF PREMISES
                 ---------------

     Tenant shall use the Premises solely for the purposes of maintaining an
office and manufacturing facility.  No other use shall be permitted without
prior written consent of
<PAGE>

Landlord and Shawmut Bank N.A. or its subsidiary, or such other individual or
institution as may be holding a mortgage on the Premises during the term hereof.

Tenant shall at its own cost and expense, promptly observe and comply with all
laws, ordinances, requirements, orders, directive, rules and regulations of the
federal, state, county, municipal or town governments and of all governmental
authorities affecting the Premises and Improvements, whether the same are in
force at the commencement of the term of this lease or may be in the future
passed, enacted or directed.  Provided, however, that in observing and complying
with all laws, ordinances, requirements, orders, directives, rules and
regulations of all governmental authorities, Tenant shall not be required, at
its expense, to make any structural repairs or changes in the Improvements or
any nonstructural repairs or changes in the Improvements or any nonstructural
repairs made necessary by defects in construction.

     Tenant shall not use or permit the Premises to be used for any purpose
other than as specified herein and shall not use or permit the Premises to be
used for any unlawful, immoral, or disreputable purposes, not for any use or
occupation which would be in conflict with provisions of the Zoning Ordinance of
the Town of Deerfield, Massachusetts, applicable to the use and occupancy of
said Premises, or which would jeopardize or invalidate any of the insurance
coverage on said Premises or which would violate the restriction applicable to
the use of property in the Deerfield Industrial Park (the "Park Restriction").

     ARTICLE 5.  PAYMENT OF UTILITY CHARGES
                 --------------------------

     Tenant shall after the Commencement Date furnish and pay for its own gas,
water, telephone, electricity, sewage, including the installation of any meters
to calculate flowage, refuse disposal, and other utility services used or wasted
by it on said Premises.  Gas, water and electricity shall be separately metered

     Tenant shall pay when due as Additional Rent, all state, city and county
real estate taxes, assessments, and other charges, including annual fees of the
Deerfield Economic Development and Industrial Corporation, that become due and
payable in connection with the premises, and any Improvements now thereon or
hereafter placed upon said Premises during the original term of this Lease or
during any extended terms in the event Tenant exercises its option to extend.
In the event of any such taxes, assessments, or charges levied on the Premises
may be paid on an installment basis, Landlord agrees to choose this method of
payment and Tenant shall be obligated to pay only those installments which
become due during the original term hereof or any renewal or extension thereof,
provided, however, that if the first mortgagee of the Landlord shall require the
payment of taxes, assessments, or charges on a periodic basis the Tenant shall
make such payments accordingly.

     In the event the Premises are not separately assessed, but are a part of a
larger tax parcel, real estate taxes applicable to the Premises shall be a
prorata share of all real estate taxes levied
<PAGE>

or assessed with respect to any tax period during the term hereof against the
land and Improvements comprising the tax parcel. Such prorata share shall be
determined as follows:

     1. The amount of real estate taxes assessment with respect to any such tax
     period against the land comprising the tax parcel multiplied by a fraction,
     the numerator of which shall be the number of square feet of land area in
     the Leased Premises and the denominator of which shall be the number of
     square feet of land area in the tax parcel;

     2. The amount of real estate taxes assessed with respect to any such tax
     period against the Improvements located upon the tax parcel multiplied by a
     fraction, the numerator of which shall be the number of square feet of
     floor area then located on the Leased Premises and the denominator of which
     shall be the number of square feet of floor area in the buildings so
     assessed which are located on the tax parcel (including, but not limited to
     Improvements located on the Leased Premises).

     It is the intention of the parties hereto that Tenant shall pay the tax
assessment herein provided for a period equal to the original term or any
extension thereof, regardless of when such taxes become a lien.  In no event
shall Tenant be required to pay such taxes for a period longer than the original
term or any extension thereof.

     It is expressly agreed, however, that Tenant shall not be required to pay,
discharge or remove any taxes, assessments, charges or levies against the
Premises, or any part thereof, which Tenant may deem illegal or excessive or to
pay any judgments rendered therefor so long as Tenant shall at its own expense,
in good faith, contest the same or the validity thereof by proper proceedings
which shall operate to prevent the collection of the tax, assessment, lien or
imposition so contested on the sale of said Premises, or any part thereof, to
satisfy the same, so long as Tenant shall furnish to Landlord and its first
Mortgagee indemnity satisfactory to them against any loss or damage by reason of
such contest, including all costs and expenses thereof,  and that pending any
such legal proceedings, and Landlord shall not have the right to pay or
discharge such tax or assessments thereby contested.  In any such case, Tenant
shall fully protect and preserve the title and rights of Landlord as well as
Tenant's leasehold estate in and to the Premises.

     ARTICLE 7.  HAZARD INSURANCE
                 ----------------

     During the term of this Lease or any extensions thereof Tenant at its own
expense, covenants that it will keep the Improvements now standing upon, or
which may hereafter be erected upon, the Premises insured against loss or damage
by fire and the hazards covered by extended coverage insurance in a responsible
insurance company or companies authorized to do business in the Commonwealth of
Massachusetts and to maintain such insurance at all times during the original
term of this Lease or any extensions thereof in an amount equal to not less than
the greater of $2,925,000 or the full insurable value of said Improvements.  The
policy or policies thereof shall be taken out by Tenant and shall name Landlord
as an additional insured and each Mortgagee of the Landlord under the standard
Massachusetts mortgage clauses.  Tenant shall provide Landlord and its
Mortgagees with a Certificate of Insurance in evidence of such
<PAGE>

coverage. Should Tenant fail to carry such fire and extended coverage insurance,
Landlord or its Mortgagees may at its option cause such insurance as aforesaid
to be issued, and in such event, Tenant agrees to pay the premiums for such
insurance upon Landlord's or Mortgagee's demand, as additional rent.

     Tenant shall be solely responsible for obtaining any fire or extended
coverage insurance for its personal property and improvements of Tenant and for
all goods, commodities and materials stored by Tenant in or about the Premises.

     ARTICLE 8.  LIABILITY INSURANCE
                 -------------------

     At all times during the term hereof or any extension thereof, Tenant at its
own expense shall maintain and keep in force for the mutual benefit of Landlord
and Tenant general public liability insurance against claims for personal
injury, death or property damage occurring in or about the Premises or sidewalks
or areas adjacent to the Premises to afford protection to the combined single
limit of not less than One Million and 00/100 ($1,000,000.00) Dollars in respect
to injury or death to persons and property damage.  The policy or policies shall
name the Landlord as an additional insured.  In order to evidence the coverage
in effect, the Tenant shall provide the Landlord with a Certificate of Insurance
and will obtain a written obligation from the insurers to notify Landlord in
writing at least ten (10) days prior to cancellation or refusal to renew any
such policies.  Should Tenant fail to carry such public liability insurance,
Landlord may, at its option, cause public liability insurance as aforesaid to be
issued, and in such event, Tenant agrees to pay the premiums for such insurance
promptly, upon Landlord's demand, as additional rent.

     ARTICLE 9.  INDEMNIFICATION
                 ---------------

     Except as hereinafter provided, Tenant shall indemnify and save Landlord
harmless from and against any and all liability, claims, damages, penalties, or
judgments arising from or in any way connected with injury to person or property
sustained in action in and about the Premises in custody and control of Tenant,
during the term of this Lease.  If Landlord shall, without fault on its part, be
made a part of any litigation commenced by or against Tenant, Tenant shall
protect and hold Landlord harmless and pay all costs, expenses and reasonable
attorneys fees that may be incurred or paid by Landlord in enforcing the
covenants and agreements of this Lease.

     Except for the negligence of the Landlord or the negligence of Landlord's
officers, agents, servants, employees or contractors, Landlord shall not be
responsible or liability for any damage or injury to any property, fixtures,
buildings or other Improvements, or to any person or person at any time on the
Premises, including any damage or injury to Tenant or to any of Tenant's
officers, agents, servants, employees, contractors, customers or sublessees.

     ARTICLE 10.  MAINTENANCE AND REPAIRS
                  -----------------------

     Tenant will repair and maintain the Leased Premises at Tenants' own
expense, and make every repair and replacement which may be needed to maintain
the Improvements, water, sewer,
<PAGE>

pumping and heating systems, plumbing system, electrical wiring system,
sprinkler system and air conditioning in good condition and repair as the same
shall be on the Commencement Date. Tenant agrees to replace all glass with
glazing of the same size and quality of that broken. Tenant shall also maintain
and repair at its expense, lawn, landscaping, exterior paving and snow removal
where applicable. Notwithstanding any other provision of this Lease, the Tenant
shall not be required to make any repair to the structural members, including
roof, exterior walls, and foundations, of the Premises, except to such extent
such repairs are necessitated by the negligence of Tenant or Tenant's
overloading the floor or other structural elements or by Tenant's having made
substantial additional improvements to the Premises after the Commencement Date
repair and maintenance of which shall be the responsibility of the Tenant.

     As of the commencement Date the Landlord will warrant that all structural
and mechanical systems of Buildings 1 and 2 are in good working order and
repair.  Tenant shall have the benefit of all contractor and subcontractor
warranties relative to the Improvements.

     If the repairs required to be made by Landlord or Tenant are not completed
within a reasonable time after request for such repair by the other party,
Landlord or Tenant, as the case may be, shall have the option to make such
repairs after first giving the other party fifteen (15) days notice of its
intention to do so, and any amounts expended by virtue thereof shall be added to
or subtracted from the next month's rent in the full amount of the expenditures.

     ARTICLE 11.  ALTERATIONS AND ADDITIONS
                  -------------------------

     Tenant at its expense, shall have the right to make such nonstructural
changes in the interior of the Premises, as it shall deem necessary or advisable
in adapting the Premises for its use.  No structural changes shall be made
without the prior written consent of Landlord, which consent shall not be
unreasonably withheld.  All changes, alterations or installments shall be of
first class construction and shall, if required, be made only after obtaining
all permits for the same.  The Tenant shall immediately pay all charges for such
changes, alterations or installations and shall not permit any liens for unpaid
labor or materials to arise.

     All fixtures shall become a part of the Premises and the property of the
Landlord at the termination of the Lease except that trade fixtures, machinery
and equipment installed by Tenant shall be considered as its own and Tenant may
recover same at any time during the term of this Lease or any extension thereof,
provided that Tenant shall repair any damage caused to said Premises by such
removal.

     ARTICLE 12.  DAMAGE OR DESTRUCTION OF IMPROVEMENTS
                  -------------------------------------

     In the event the Premises shall be rendered untenantable by insured
casualty, the Landlord will within one hundred twenty (120) days from the date
of said damage or destruction, repair and replace said Premises to substantially
the same condition as prior to the damage or destruction less wear and tear
caused by Tenant's use and occupation.  If the Landlord fails to commence repair
of the damage or destruction within ten (10) business days (unless the repair or
restoration is of such character that it cannot be commenced within such time,
provided that in
<PAGE>

any event that commencement thereof will occur within thirty (30) days of such
damage or destruction) from the date of such damage or destruction, or if the
Premises have not been replaced or repaired to such condition within one hundred
twenty (120) days, Tenant may at its option, (to be exercised by written notice
to the Landlord and to the Trustee) terminate this Lease. The Base Rent herein
required to be paid shall abate during the period of such untenantability.

     If the premises shall be damaged in part by insured casualty, but still
remain tenantable, the landlord shall repair said Premises to substantially the
same condition as prior to the damage less wear and tear caused by Tenant's use
and occupation.  Landlord shall commence repair of the damage or destruction
within thirty (30) days from the date of occurrence.  During the period of such
repairs and restorations, the Lease shall continue in full force and effect,
provided, however, that Tenant shall be required to pay the Base Rent, herein
reserved, abated by the percentage of area destroyed as compared to the total
area herein demised.

     In the event that any damage or destruction occurring during the last
twelve (12) months of the original or extended term of this Lease to the extent
of ten (10%) percent or more of the insurable value of the Premises, Landlord or
Tenant may elect to terminate this Lease as of the date of the destruction or
damage, by giving notice of such election to the other and to the Trustee within
fifteen (15) days after such damage or destruction provided, however, that if
Tenant has exercised its option to purchase the Premises no such termination
shall take place and upon the payment of the purpose price the proceeds of
insurance shall be paid to the tenant.

     Except as otherwise provided in the preceding paragraph, the Tenant shall
cause all insurance proceeds to be assigned to the Landlord in the event of fire
or other insured damage to be used for repair or restoration.  In no event shall
the Landlord's obligations herein to restore the premises in the event of damage
or casualty exceed the amount of insurance proceeds made available to landlord
by the insurance carrier and released to Landlord by its Mortgagees for such
repair and/or restoration.

     ARTICLE 13.  LANDLORD'S RIGHT TO ACCESS
                  --------------------------

     Tenant shall permit Landlord and Trustee and their agents to enter upon
said Premises at all reasonable times during business hours to examine the
condition of the same, provided that Landlord and/or Trustee gives Tenant
twenty-four (24) hour notice thereof except for in time of emergency, and
provided further that such entry is consistent with the Tenant's security
regulations, and shall permit Landlord and/or Trustee to make such repairs as
may be required.  Tenant shall permit Landlord for a period of one hundred
eighty (180) days prior to the expiration of the original or extended term of
this Lease, to place upon the Premises the usual "For Rent" or "For Sale" signs,
and shall permit Landlord and his agents, at reasonable times, to conduct
prospective Tenants or Purchasers through said Premises after giving notice as
aforesaid.
<PAGE>

     ARTICLE 14.  SURRENDER OF PREMISES
                  ---------------------

     Tenant shall surrender and deliver up said Premises and appurtenances at
the end of said term broom-clean and in as good condition and order as they were
at commencement of the term hereof, reasonable use and ordinary wear and tear
thereof and damage by fire or other casually and leasehold improvements made
with Landlord's consent excepted.  Tenant may remove all the trade fixtures,
signs, equipment, stock and trade, and other items of a similar nature used in
connection with its business, including such as may have been temporarily
attached to the realty, provided all rents stipulated to be paid hereunder have
been paid and all damage to said Premises is properly repaired.  If said removal
results in injury to or defacement of said Premises, Tenant shall immediately
repair the Premises at its expense.

     ARTICLE 15.  SIGNS
                  -----

     Tenant shall have the privilege and right of placing on the Premises such
signs as it deems necessary and proper in the conduct of its business subject to
Landlord's prior written approval, which approval may not be unreasonably
withheld.  Tenant shall comply with all laws, ordinances, deed and municipal
regulations and Industrial Park Restrictions applicable to the erection,
maintenance and the removal of said signs.  Any damage to any Improvements by
said signs shall be restored by Tenant forthwith at its expense.

     ARTICLE 16.  ASSIGNMENT AND SUBLETTING
                  -------------------------

     Provided Tenant is not in default of any of the terms, conditions or
covenants contained in this Lease, Tenant may assign this Lease or sublet the
Premises or any part thereof after first obtaining the prior written consent of
Landlord and Trustee which consent shall not be unreasonably withheld and upon
the further condition that the use of the property by a sublessee or assignee
are permitted by Municipal Ordinance, Industrial Park Restrictions, and that
such use will not create any default under any mortgage against the Premises.
No assignment or subletting consented to by Landlord shall relieve Tenant from
its liability hereunder, and each and every assignee or sublessee shall be
charged with all of the provisions hereof by a separate writing.  Tenant shall
provide Landlord and Trustee with written identification of  subtenant or
assignee, and terms of such subletting or assignment.

     ARTICLE 17.  EMINENT DOMAIN
                  --------------

     If the entire Premises, or such part thereof, as, in the parties' judgment,
renders the remainder unsuitable for Tenant's continued use, shall be taken in
appropriation proceedings or by any rights of eminent domain, then this Lease
shall terminate and be void from the time when possession thereof is required
for public use, and such taking shall not operate as or be deemed an eviction of
the Tenant or a breach of Landlord's covenant for quiet enjoyment; but Tenant
shall pay all rent due, and perform and observe all other covenants hereof, up
to the time when possession is required for public use.  Provided, however, that
if only a part of said Premises be so taken and in the Landlord and Tenant's
judgment the Leased Premises remain unsuitable for Tenant's continued use, and
if two (2) years or more of the term hereof then remains unexpired,
<PAGE>

and if the remaining Premises can be substantially restored within sixty (60)
days, then this Lease shall not terminate, but Landlord will, at its sole
expense, restore the Leased Premises. Rent payable by Tenant during the period
of restoration shall be reduced by a reasonable amount, but after such
restoration, the rent herein reserved shall be paid by Tenant as herein provided
during the remainder of the term hereof abated by the percentage that the fair
market value of the Premises, attributable solely to the land and Improvements,
has been reduced because of such taking. Said market value immediately before
and after such taking shall be determined by agreement of the parties or,
failing agreement of the parties within thirty (30) days of the effective date
of such taking, by a local Independent Fee Appraiser selected by mutual
agreement of Landlord and Tenant, which appraiser's decision will be final and
binding on the parties. The cost of such appraiser shall be borne equally by
Landlord and Tenant.

     Tenant shall have the right at its sole cost and expense to assert a
separate claim or join in Landlord's claim in any condemnation proceeding for
its personal property, its improvements, moving expenses, or any other claims it
may have; provided, however, that no award to the Tenant shall reduce the award
which would otherwise be due the Landlord and in no event prevent the Mortgagee
from collecting award proceeds.  Tenant shall be entitled to and shall receive
that portion of any award or payment made which is attributable solely to its
claim, as set forth above and Landlord shall be entitled to and shall receive
that portion of any award of payment made which is attributable solely to the
land and Improvements erected thereon.

     ARTICLE 18.  DEFAULT
                  -------

     The following events shall be deemed to be events of default by Tenant
under this Lease:

     a. Tenant shall fail to pay any installment of the rent hereby reserved and
such failure shall continue for fifteen (15) days.

     b. Tenant shall fail to comply with any term, provision or covenant of this
Lease, other than the payment of rent, and shall not cure such failure within
thirty (30) days after due written notice thereof to Tenant; or if such failure
shall be of such a nature that the same cannot be completely cured within the
said thirty (30) days and Tenant shall not have commenced to cure such failure
within such thirty (30) day period and shall not thereafter with reasonable
diligence and good faith proceed to cure such failure.

     c. Tenant shall become insolvent, or shall make a transfer in fraud of
creditors, or shall make an assignment for the benefit of creditors.

     d. Tenant shall file a petition under any section or chapter of the
National Bankruptcy Act, as amended, or under any similar law or statute of the
United States or any State thereof; or an involuntary petition in bankruptcy
shall be filed against Tenant thereunder.

     e. A receiver or trustee shall be appointed for all or substantially all of
the assets of Tenant.
<PAGE>

     f. Tenant shall abandon or vacate the Premises during the term of this
Lease for a period in excess of three (3) months.

     g. Tenant or anyone claiming under or through Tenant shall use the premises
in violation of zoning ordinances or in material violation of Park Restrictions.

     h. Tenant or anyone claiming under or through Tenant shall use the Premises
in violation of the covenants of any mortgage applicable to the Premises.

     Upon the occurrence of any of such events of default, Landlord shall have
the right, at Landlord's election subject to rules relating to government
security to pursue, in addition to and cumulative of any other rights Landlord
may have, at law or in equity, any one or more of the following remedies without
any notice or demand whatsoever:

     a)  Terminate this Lease, in which event Tenant shall immediately surrender
the Premises to Landlord, and if Tenant fails so to do, Landlord may, without
prejudice to any other remedy which it may have for possession or arrearages in
rent, enter upon and take possession of the demised premises and expel or remove
Tenant and any other person who may be occupying said Premises or any part
thereof, without being liable for prosecution or any claim of damages therefore;
and Tenant agrees to pay to Landlord on demand the amount of all loss and damage
which Landlord may suffer by reason of such termination.

     b)  Enter upon and take possession of the demised Premises and expel or
remove Tenant and any other person who may be occupying said Premises or any
part thereof without being liable for prosecution or any claim for damages
therefore, and relet the Premises and receive the rent thereof; crediting Tenant
therefore; and Tenant agrees to pay to Landlord on demand any deficiency that
may arise by reason of such reletting.

     c)  Enter upon the demised Premises without being liable for prosecution of
any claim for damages therefore, and do whatever Tenant is obligated to do under
the terms of this Lease, and Tenant agrees to reimburse Landlord on demand for
any expense which Landlord may incur in thus effecting compliance with Tenant's
obligations under the Lease, and Tenant further agrees that Landlord shall not
be liable for any damages resulting to the Tenant from such action, whether
caused by the negligence of Landlord or otherwise.

     d)  Require all rental payments by "subtenants" (including within that term
the third parties occupying various portions of the demised Premises under the
terms of Lease agreements with Tenant, as primary lessor or as sublessor) which
would otherwise be paid to Tenant to be paid directly to Landlord and apply such
rentals so paid to or collected by Landlord against any rents or other charges
due to Landlord by Tenant hereunder.  No direct collection by Landlord from any
such "subtenants" shall release Tenant from the further performance of Tenant's
obligations hereunder.

     Pursuit of any of the foregoing remedies shall not preclude pursuit of any
of the other remedies herein provided or any other remedies provided by law, nor
shall pursuit of any remedy
<PAGE>

herein provided constitute a forfeiture or waiver of any rent due to Landlord
hereunder or of any damages accruing to Landlord by reason of the violation of
any of the terms, provisions and covenants herein contained. Failure by Landlord
to enforce one or more of the remedies herein provided upon an event of default
shall not be deemed or construed to constitute a waiver of such default or of
any other violation or breach of any of the terms, provisions and covenants
herein contained. In determining the amount of loss or damage which Landlord may
suffer by reason of termination of this Lease or the deficiency arising by
reason of the reletting by Landlord as above provided, allowance shall be made
for the expense of repossession and any repairs. The Landlord shall use
reasonable efforts to relet the Leased Premises on commercially reasonable terms
and to apply all rents received in reduction of the Tenant's liability
hereunder.

     ARTICLE 19.  OPTION TO PURCHASE
                  ------------------

     a. Landlord grants Tenant the option, exercisable by Tenant at any time
during the term and any extension of this Lease, to purchase the Premises at a
purchase price in 1990 of Two Million, Nine Hundred Twenty-five Thousand Eight
Hundred Sixty-six ($2,925,866) which price shall increase at the rate of four
(4) percent per annum on the first day of each calendar year after 1990 during
the term and any extension of this Lease.

Tenant shall exercise its option to purchase by notice in writing thereof
delivered to or mailed by registered or certified mail to Landlord at Landlord's
address, which notice shall specify a closing date of not more than sixty (60)
days and not less than thirty (30) days from the date thereof.  On the closing
date so specified or such other closing date as may be otherwise mutually agreed
upon between the parties, Landlord shall deliver to Tenant a good and sufficient
quitclaim deed running to Tenant or to the nominee designated in writing by
Tenant to Landlord prior to the closing date, which deed shall convey to Tenant
or Tenant's nominee a good and clear record and marketable title to the Premises
free and clear from all liens, encumbrances and restrictions, except:

     1.  Provisions of existing building and zoning laws;

     2. Such taxes for the then current year as are not due and payable on the
     date of delivery of such deed; and

     3. Such other easements, restrictions and encumbrances of record which do
     not materially interfere with the continuing use and operations of the
     Premises.

Upon the delivery of such deed Tenant shall pay Landlord the purchase price in
full in cash or by bank or certified check and there upon all obligations of
Tenant under this Lease with respect to the Premises shall cease and determine
(except that the rent shall be apportioned as of such date).

     b. In the event Landlord is unable to deliver the Premises to Tenant upon
the exercise of its option to purchase, this Lease shall automatically revive
and continue for a period of sixty (60) days during which time Landlord shall
use its best efforts (said obligation being limited by Landlord's expectation of
net proceeds from said sale) to deliver title to Tenant at the end of said
period. At the end of said sixty (60) days, tenant may elect to continue this
lease or terminate this lease, vacating the premises promptly.

     ARTICLE 22.  SUBORDINATION AND NONDISTURBANCE
                  --------------------------------

     This Lease and all of the rights of Tenant hereunder are and shall be
subject and subordinate to the lien of any mortgage or mortgages hereinafter
placed on the Premises or any part thereof, except the Tenant's property or
trade fixtures, and to any and all renewals, modifications, replacements,
extensions or substitutions of any such mortgage or mortgages (all of which are
hereinafter termed the mortgage or mortgages) provided, nevertheless, each or
all of such mortgage or mortgages shall contain a provision to the effect that
so long as the Tenant is not in default under this Lease, or any renewal
thereof, no foreclosure of the lien of said mortgage or any other proceeding in
respect thereof shall divest, impair, modify, abrogate or otherwise adversely
effect any interest or rights whatsoever of the Tenant under the said Lease.

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

     Any Mortgagee of the Landlord shall have the following rights:

     a. Any notice required to be given to the Landlord by the Tenant shall be

Landlord or shall have any excuse from the performance of any obligation imposed
upon the Tenant by the terms of this Lease then and in such event, the tenant
shall give notice of its intended exercise of such right in the manner provided
for herein to the Mortgagee and thereafter the Trustee shall have the right, but
not the obligation, to cure said defaults within the time provided for cure of
the same as set forth in this Lease.

     c.  Upon the request of the Mortgagee or any assignee of the Mortgagee the

     ARTICLE 24.  HOLDOVER
                  --------

     In the event Tenant remains in possession of the demised Premises after the
expiration of this Lease, it shall operate and be construed to be a tenancy from

Dear Mr. Bolotin:

As I mentioned in my voice mail message, we inadvertently left the roof coating
off of our previous listing of renovation tasks. Please understand that although
our new estimate exceeds $140,000, we would not expect Mr. Greene's contribution
to be greater than $70,000.

attached hereto (individually, a "Stockholder" and collectively, the
"Stockholders"), and the persons or entities who are listed on Schedule II
attached hereto (individually, a "Purchaser" and collectively, the

     WHEREAS, the Third Amended and Restated Registration Rights Agreement dated
as of October 27, 1998 by and among the Company and the Stockholders (the
"Registration Agreement") grants the Stockholders certain rights with respect to
certain securities of the Company;

     WHEREAS, the Purchasers have agreed to purchase up to 6,666,667 shares of
Class E Preferred Stock, par value $.01 per share, of the Company (the "Class E
Preferred Stock") pursuant to a Stock Purchase Agreement between the Company and
the Purchasers (the "Class E Agreement") of even date herewith; and

     WHEREAS, the parties desire to amend and restate the Registration Agreement
in order to take into account the issuance of additional Class E Preferred
Stock, such amendment being a condition precedent to the execution, delivery and
performance of the Class E Agreement;

     NOW THEREFORE, in consideration of the transactions contemplated by the
Class E Agreement and other good and valuable consideration, the receipt and

     Section 2.  Requested Registration.
     ----------------------------------

     (a) Request for Registration.  If at any time after the earlier to occur of
         ------------------------
(i) the third anniversary of the date hereof and (ii) the date which is six
months after the Initial Public Offering, the Company shall receive from
Initiating Holders, a written request that the Company effect any registration
with respect to all or a part of the Registrable Securities, the Company will:

         (i)  promptly give written notice of the proposed registration to all
other Holders and the holders of the Warrants at least 45 days prior to the date
the Company anticipates filing the registration statement covering the
Registrable Securities so requested to be registered; and

         (ii)  as soon as practicable, use its diligent best efforts to effect
such registration as may be so requested and which would permit or facilitate
the sale and distribution of all or such portion of such Registrable Securities
as are specified in such request, together with all or such portion of the
Registrable Securities of any Holder or Holders joining in such request as are
specified in a written request given within 30 days after receipt of such
written notice from the Company.  The Company shall not be obligated to effect
any registrations pursuant to this Section 2 after the Company shall have
effected two such registrations pursuant to this Section 2 and such
registrations shall have been declared or ordered effective by the Commission
and the sales of such Registrable Securities shall have closed.

     The registration statement filed pursuant to the request of the Initiating
Holders may, subject to the provisions of Section 2, include securities of the
Company for its own account, or other securities of the Company which are held
by officers or directors of the Company or which are held by persons who, by
virtue of agreements with the Company, are entitled to include their securities
in any such registration.

     (b) Underwriting.  If the Initiating Holders intend to distribute the
         ------------
Registrable Securities covered by their request by means of an underwriting,
they shall so advise the Company as a part of their request made pursuant to
paragraph 2 hereof and the Company shall include such information in the written
notice referred to in Section 2(a)(i).  The right of any Holder to registration
pursuant to this Section 2 shall be conditioned upon such Holder's participation
in such underwriting and the inclusion of such Holder's Registrable Securities
in the underwriting (unless otherwise mutually agreed by a majority in interest
of the Initiating Holders

                                       3
<PAGE>

and such Holder with respect to such participation and inclusion) to the extent
provided herein. A Holder may elect to include in such underwriting all or a
part of the Registrable Securities it holds.

     If officers or directors of the Company holding other securities of the
Company shall request inclusion in any registration pursuant to this Section 2,
or if Other Shareholders request such inclusion, the Initiating Holders shall,
on behalf of all Holders, offer to include the securities of such officers,
directors and Other Shareholders in the underwriting and may condition such
offer on their acceptance of the further applicable provisions of this
Agreement.  The Company shall (together with all Holders, officers, directors
and Other Shareholders proposing to distribute their securities through such
underwriting) enter into an underwriting agreement in customary form with the
representative of the underwriter or underwriters selected for such underwriting
by a majority in interest of the Initiating Holders and reasonably acceptable to
the Company.  Notwithstanding any other provision of this Section 2, if the
representative of the underwriter advises the Initiating Holders in writing that
marketing factors require a limitation on the number of shares to be
underwritten, the securities of the Company held by officers or directors (other
than Registrable Securities) of the Company shall be excluded from such
registration to the extent so required by such limitation and if a limitation of
the number of shares is still required, the Initiating Holders shall so advise
all Other Shareholders whose securities would otherwise be included pursuant to
the request described herein, and the number of other securities that may be
included in the registration and underwriting shall be allocated among all such
Other Shareholders in proportion, as nearly as practicable, to the respective
amounts of securities which they had requested to be included.  If a limitation
of the number of shares is still required, the Initiating Holders shall so
advise all Holders whose Registrable Securities would otherwise be included
pursuant to the request described herein, and the number of Registrable
Securities that may be included in the registration and underwriting shall be
allocated among all such Holders in proportion, as nearly as practicable, to the
respective amounts of Registrable Securities which they  had requested be
included.  No Registrable Securities or any other securities excluded from the
underwriting by reason of the underwriter's marketing limitation shall be
included in such registration.  If any Holder of Registrable Securities,
officer, director or Other Shareholder who has requested inclusion in such
registration as provided above disapproves of the terms of the underwriting,
such person may elect to withdraw therefrom by written notice to the Company,
the underwriter and the Initiating Holders.  The securities held by such person
shall then be withdrawn from registration.  If the underwriter has not limited
the number of Registrable Securities or other securities to be underwritten, the
Company may include its securities for its own account in such registration if
the underwriter so agrees and if the number of Registrable Securities and other
securities which would otherwise have been included in such registration and
underwriting has not thereby been limited.

     Section 3.  Company Registration.
     --------------------------------

     (a) If 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 a registration relating
solely to a Commission Rule 145 transaction,

                                       4
<PAGE>

or a registration on any registration form which does not permit secondary
sales or does not include substantially the same information as would be
required to be included in a registration statement covering the sale of
Registrable Securities, the Company will:

         (i)  promptly give to each Holder and each holder of a Warrant written
notice thereof; and

         (ii) include in such registration and in any underwriting involved
therein, all the Registrable Securities specified in a written request or
requests, made by any Holder within 15 days after receipt of the written notice
from the Company described in clause (i) above, except as set forth in Section
3(b).  Such written request may specify all or a part of a Holder's Registrable
Securities be included in the Company's registration.

     (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
3(a)(i).  In such event the right of any Holder to registration pursuant to
Section 3 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 Shareholders distributing their securities through such underwriting)
enter into an underwriting agreement in customary form with the underwriter or
underwriters selected for underwriting by the Company.  Notwithstanding any
other provision of Section 3, if the underwriter determines that marketing
factors require a limitation on the number of shares to be underwritten, and (a)
if such registration is the Initial Public Offering, the underwriter may
(subject to the allocation priority set forth below) exclude from such
registration and underwriting some or all of the Registrable Securities which
would otherwise be underwritten pursuant to the notice described herein, and (b)
if such registration is other than the Initial Public Offering, the underwriter
may (subject to the allocation priority set forth below) limit the number of
Registrable Securities to be included in the registration and underwriting to
not less than fifty percent (50%) of the securities included therein (based on
aggregate market values).  The Company shall so advise all holders of securities
requesting registration, and the number of shares of securities that are
entitled to be included in the registration and underwriting shall be allocated
in the following manner.  The securities of the Company held by officers and
directors of the Company (other than Registrable Securities) shall be excluded
from such registration and underwriting to the extent required by such
limitation, and, if a limitation on the number of shares is still required, the
number of shares that may be included in the registration and underwriting shall
be allocated among all such Holders and Other Shareholders in proportion, as
nearly as practicable, to the respective amounts of Registrable Securities and
other securities which they had requested to be included in such registration at
the time of filing the registration statement, except that Registrable
Securities held by any of the Purchasers, or any other Holder shall be the last
to be limited.  If any Holder of Registrable Securities or any officer, director
or Other Shareholder disapproves of the terms of any such underwriting, he may
elect to withdraw therefrom by written notice to the Company

                                       5
<PAGE>

and the underwriter. Any Registrable Securities or other securities excluded or
withdrawn from such underwriting shall be withdrawn from such registration.

     Section 4.  Registration on Form S-2 or Form S-3.  The Company shall use
     ------------------------------------------------
its best efforts to qualify for registration of its securities on Form S-2 or
Form S-3 or any comparable or successor form or forms; the Company shall
register (whether or not required by law to do so) the Common Stock under the
Exchange Act in accordance with the provisions thereof, following the effective
date of the first registration of any securities of the company on Form S-1 or
Form S-18 or any comparable or successor form or forms.  If, at any time after
the Corporation becomes eligible to file a registration statement on Form S-2 or
S-3 (or any successor form regardless of its designation), the Corporation shall
receive a written request from any Holder or Holders of twenty percent (20%) of
the then-outstanding Registrable Securities that the Corporation file a
registration statement on Form S-2 or S-3 (or any successor form regardless of
its designation) for a public offering of shares of the Registrable Securities
the reasonably anticipated aggregate price to the public of which would exceed
One Million Dollars ($1,000,000), then the Corporation shall use its best
efforts to cause such shares to be so registered.

     Section 5.  Expenses of Registration.  All Registration Expenses incurred
     ------------------------------------
in connection with any registration pursuant to Section 2 or 3 shall be borne by
the Company; provided, however, that the Company shall not be required to pay
any Registration Expenses if, as a result of the withdrawal of a request for
registration by Initiating Holders, the registration statement does not become
effective, in which case the Holders and Other Shareholders requesting
registration shall bear such Registration Expenses pro-rata on the basis of the
number of their shares so included in the registration request, and provided,
further, that such registration shall not be counted as a requested registration
pursuant to Section 2(a)(ii)(B).  All Registration Expenses incurred in
connection with the first two registrations pursuant to Section 4 shall be borne
by the Company; thereafter such Registration Expenses shall be borne by the
selling Holder or Holders.

     Section 6.  Registration Procedures.  In the case of each registration
     -----------------------------------
effected by the Company pursuant to this Agreement, the Company will keep each
Holder advised in writing as to the initiation of each registration and as to
the completion thereof.  At its expense, the Company will:

     (a) Prepare and file with the Commission a registration statement covering
the Registrable Securities requested to be registered as expeditiously as
reasonably possible and keep such registration effective for a period of nine
months; provided, however, that (i) such nine-month period shall be extended for
a period of time equal to the period the Holder refrains from selling any
securities included in such registration in accordance with the provisions of
Section 11; and (ii) in the case of any registration of Registrable Securities
on Form S-3 which are intended to be offered on a continuous or delayed basis,
such nine-month period shall be extended, if necessary, to keep the registration
statement effective until all such Registrable Securities are sold, provided
that Rule 415, or any successor rule under the Act, permits an

                                       6
<PAGE>

offering on a continuous or delayed basis, and provided further that applicable
rules under the Act governing the obligation to file a post-effective amendment
permit, in lieu of filing a post-effective amendment which (y) includes any
prospectus required by Section 10(a)(3) of the Act or (z) reflects facts or
events representing a material or fundamental change in the information set
forth in the registration statement, the incorporation by reference of
information required to be included in (y) and (z) above to be contained in
periodic reports filed pursuant to Section 13 or 15(d) of the Exchange Act in
the registration statement;

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

     (c) Use its best efforts to register and qualify the securities covered by
such registration statement under such other securities or Blue Sky laws of such
jurisdictions as shall be reasonably appropriate for the distribution of the
securities covered by the registration statement, provided that the Company
shall not be required in connection therewith or as a condition thereto to
qualify to do business or to file a general consent to service of process in any
such states or jurisdictions;

     (d) Provide a transfer agent for the Common Stock no later than the
effective date of the first registration of any Registrable Securities;

     (e) Otherwise use its best efforts to comply with all applicable rules and
regulations of the Commission;

     (f) Use its best efforts to cause all the Registrable Securities either (i)
to be listed on a national securities exchange (if the Registrable Securities
are not already so listed) and on each additional national securities exchange
on which similar securities issued by the Company are then listed, if the
listing of the Registrable Securities is then permitted under the rules of such
exchange, or (ii) to secure designation of all the Registrable Securities as a
NASDAQ "national market system security" within the meaning of Rule 11Aa2-1 of
the Commission or, failing that, to secure listing on NASDAQ for the Registrable
Securities and, without limiting the generality of the foregoing, to arrange for
at least two (2) market makers to register as such with respect to Registrable
Securities with the National Association of Securities Dealers, Inc.;

     (g) Enter into such customary agreements (including an underwriting
agreement in customary form) and take such other actions as sellers of
Registrable Securities shall reasonably request in order to expedite or
facilitate the disposition of such Registrable Securities;

     (h) In the case of an underwritten offering, on the date of delivery of the
Registrable Securities sold pursuant thereto, cause to be delivered to the
selling Holders and the underwriters, opinions of counsel for the Company, which
counsel and opinions (in form, scope and substance) shall be reasonably
satisfactory to counsel for the underwriters and counsel for the selling
Holders, covering the matters customarily covered in opinions given to
underwriters in primary underwritten public offerings.  At the time of delivery
of any Registrable Securities sold pursuant

                                       7
<PAGE>

to an underwritten offering, the Company shall cause to be delivered to the
selling Holders and the underwriters a letter from the Company's independent
public accountants, addressed to the underwriters and the selling Holders,
stating that they are independent public accountants within the meaning of the
Act and the applicable published rules and regulations of the Commission
thereunder, and otherwise in customary form and covering such financial and
accounting matters as are customarily covered by letters of the independent
public accountants delivered in connection with underwritten public offerings;

     (i) Make available for inspection by any seller of Registrable Securities,
by any underwriter participating in any disposition to be effected pursuant to
such registration statement and by any attorney, accountant or other agent
retained by any such seller or any such underwriter, all pertinent financial and
other records and pertinent corporate documents and properties of the Company
and cause all of the Company's officers, directors and employees to supply all
information reasonably requested by any such seller, underwriter, attorney,
accountant or agent in connection with such registration statement; in each case
as permitted by law and contractual confidentiality restrictions;

     (j) Permit any Holder of Registrable Securities which Holder, in the sole
and exclusive judgment, exercised in good faith, of such Holder, might be deemed
to be a controlling person of the Company (within the meaning of the Act or the
1934 Act) to participate in the preparation of such registration statement and
to request the insertion therein of material, furnished to the Company in
writing, which in the judgment of such controlling Holder should be included and
which is reasonably acceptable to the Company;

     (k) Use every reasonable effort to prevent the issuance of any stop order
suspending the effectiveness of such registration statement or of any order
preventing or suspending the use of any preliminary prospectus and, if any such
order is issued, to obtain the lifting thereof at the earliest reasonable time;
and

     (l) Make such representations and warranties to the selling Holders and the
underwriters as are customarily made by issuers to underwriters and selling
Holders, as the case may be, in underwritten public offerings.

     Section 7.  Indemnification.
     ---------------------------

     (a) The Company will indemnify each Holder, each of its officers, directors
and partners, and each person who controls such Holder, with respect to which
registration, qualification or compliance has been effected pursuant to this
Agreement, and each underwriter, if any, and each person who controls any
underwriter (within the meaning of the Act and the rules and regulations
thereunder) against all claims, losses, damages and liabilities (or actions in
respect thereof) arising out of or based on any untrue statement (or alleged
untrue statement) of a material fact contained in any registration statement,
prospectus, offering circular or other document incident to any such
registration, qualification or compliance, or based on any omission (or alleged
omission) to state therein a material fact required to be stated therein or

                                       8
<PAGE>

necessary to make the statements therein not misleading, or any violation by the
Company of the Act or any rule or regulation thereunder 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 who
controls such Holder, each such underwriter and each person who controls any
such underwriter, for any legal and other expenses reasonably incurred in
connection with investigating and 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 from or is based on any untrue statement or omission or alleged untrue
statement or omission based upon written information furnished to the Company by
such Holder or underwriter and stated to be specifically for use therein.

     (b) Each Holder will, if Registrable Securities held by it are included in
the securities as to which such registration, qualification or compliance is
being effected, and each Other Shareholder who has the right to register its
securities pursuant to this Agreement will be required by the Company to,
indemnify the Company, each of its directors and officers and 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
the Act and the rules and regulations thereunder) each other such Holder and
Other Shareholder and each of their officers, directors and partners, and each
person who controls such Holder or Other Shareholder, against all claims,
losses, damages and liabilities (or actions in respect thereof) arising out of
or based on any untrue statement (or alleged untrue statement) of a material
fact contained if any such registration statement, prospectus, offering circular
or other document, or any omission (or alleged omission) to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and will reimburse the Company and such Holders, Other
Shareholders, directors, officers, partners, persons, underwriters or
controlling 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 such Holder or Other Shareholder and stated to be
specifically for use therein; provided, however, that the obligations of such
Holders and Other Shareholders hereunder shall be limited to an amount equal to
the proceeds to each such Holder or Other Shareholder of securities sold as
contemplated herein.

     (c) Each party entitled to indemnification under this Section 7 (the
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom, provided that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or any litigation resulting
therefrom, shall be approved by the Indemnified Party (whose approval shall not
unreasonably be withheld), and the Indemnified Party may participate in such
defense at such party's expense, and provided further

                                       9
<PAGE>

that the failure of any Indemnified Party to give notice as provided herein
shall not relieve the Indemnifying Party of its obligations under this
Agreement. No Indemnifying Party, in the defense of any such claim or
litigation, shall, except with the consent of each Indemnified Party (which
consent shall not unreasonably be withheld), consent to entry of any judgment or
enter into any settlement which does not include as an unconditional term
thereof the giving by the claimant or plaintiff to such Indemnified Party of a
release from all liability in respect to such claim or litigation. Each
Indemnified Party shall furnish such information regarding itself or the claim
in question as an Indemnifying Party may reasonably request in writing and as
shall be reasonably required in connection with defense of such claim and
litigation resulting therefrom.

     (d) In order to provide for just and equitable contribution to joint
liability under the Act in any case in which either (i) any Holder of
Registrable Securities exercising rights under this Agreement, or any
controlling person of any such Holder, makes a claim for indemnification
pursuant to this Section 7 but it is judicially determined (by the entry of a
final judgment or decree by a court of competent jurisdiction and the expiration
of time to appeal or the denial of the last right of appeal) that such
indemnification may not be enforced in such case notwithstanding the fact that
this Section 7 provides for indemnification in such case, or (ii) contribution
under the Act may be required on the part of any such selling Holder or any such
controlling person in circumstances for which indemnification is provided under
this Section 7; then, and in each such case, the Company and such Holder will
contribute to the aggregate losses, claims, damages or liabilities to which they
may be subject (after contribution from others) in such proportion so that such
Holder is responsible for the portion represented by the percentage that the
public offering price of its Registrable Securities offered by the registration
statement bears to the public offering price of all securities offered by such
registration statement, and the Company is responsible for the remaining
portion; provided, however, that, in any such case, (A) no such Holder of
         --------  -------
Registrable Securities will be required to contribute any amount in excess of
the net proceeds received from the sale of all such Registrable Securities
offered by it pursuant to such registration statement; and (B) no person or
entity guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Act) will be entitled to contribution from any person or entity who
was not guilty of such fraudulent misrepresentation.

     Section 8.  Information by Holder.  Each Holder of Registrable Securities,
     ---------------------------------
and each Other Shareholder holding securities included in any registration,
shall furnish to the Company such information regarding such Holder or Other
Shareholder and the distribution proposed by such Holder or Other Shareholder as
the Company may reasonably request in writing and as shall be reasonably
required in connection with any registration, qualification or compliance
referred to in Section 2, 3 or 4.

     Section 9.  Limitations on Registration of Issues of Securities.  From and
     ---------------------------------------------------------------
after the date of this Agreement, the Company shall not enter into any agreement
with any holder or prospective holder of any securities of the Company giving
such holder or prospective holder the right to require the Company to initiate
any registration of any securities of the Company, provided that this Section 9
shall not limit the right of the Company to enter any agreements with any holder
or prospective holder of any securities of the Company giving such holder or
prospective holder the

                                       10
<PAGE>

right to require the Company, upon any registration of any of its securities, to
include, among the securities which the Company is then registering, securities
owned by such holder. Any right given by the Company to any holder or
prospective holder of the Company's securities in connection with the
registration of securities shall be conditioned such that it shall be consistent
with the provisions of this Agreement and with the rights of the Holders
provided in this Agreement.

     Section 10.  Transfer or Assignment of Registration Rights.  The rights to
     ----------------------------------------------------------
cause the Company to register the Registrable Securities granted by the Company
under Sections 2, 3 and 4 may be transferred or assigned by a Holder to a
transferee or assignee of any of the Holder's Registrable Securities, provided
that the Company is given written notice by a Holder at the time of or within a
reasonable time after said transfer or assignment, stating the name and address
of said transferee or assignee and identifying the securities with respect to
which such registration rights are being transferred or assigned and provided
further that the transferee or assignee of such rights assumes the obligations
of such Holder under this Agreement.

     Section 11.  "Market Stand-off" Agreement.  Each Purchaser agrees, if
     -----------------------------------------
requested by the Company and an underwriter of Common Stock (or other
securities) of the Company, not to sell or otherwise transfer or dispose of any
Common Stock (or other securities) of the Company held by it during the time
period following the effective date of a registration statement of the Company
filed under the Act requested by the underwriter, or in the absence of such
request, 90 days, provided that:

     (a) such agreement only applies to the first such registration statement of
the Company including securities to be sold on its behalf to the public in an
underwritten offering; and

     (b) all other Holders, Other Shareholders, principal officers and directors
of the Company enter into similar agreements.

     Such agreement shall be in writing in a form satisfactory to the Company
and such underwriter.  The Company may impose stop-transfer instructions with
respect to the shares (or securities) subject to the foregoing restriction until
the end of the restricted period.

     Section 12.  Reports Under the 1934 Act.  With a view to making available
     ---------------------------------------
to the Holders the benefits of Rule 144 promulgated under the Act and any other
rule or regulation of the Commission that may at any time permit a Holder to
sell securities of the Company to the public without registration, the Company
agrees to use its best efforts to:

     (a) make and keep public information available, within the meaning of Rule
144, at all times after the effective date of (i) the first registration
statement covering an underwritten public offering filed by the Company or (ii)
registration by the Company under the 1934 Act;

                                       11
<PAGE>

     (b) following a public offering or a registration under the 1934 Act, file
with the Commission in a timely manner all reports and other documents required
of the Company under the Act and the 1934 Act; and

     (c) furnish to any Holder forthwith upon request a written statement by the
Company that it has complied with the reporting requirements of Rule 144 (at any
time after ninety (90) days after the effective date of said first registration
statement filed by the Company), and of the Act and the 1934 Act (at any time
after it has become subject to such reporting requirements), a copy of the most
recent annual or quarterly report of the Company, and such other reports and
documents filed by the Company with the Commission as may be reasonably
requested to permit any such holder to take advantage of any rule or regulation
of the Commission permitting the selling of any such securities without
registration.

     Section 13.  Mergers, Etc..  The Company shall not, directly or
     --------------------------
indirectly, enter into any merger, consolidation or reorganization in which the
Company shall not be the surviving corporation unless the proposed surviving
corporation shall, prior to such merger, consolidation or reorganization, agree
in writing to assume the obligations of the Company under this Agreement, and
for that purpose references hereunder to "Registrable Securities" shall be
deemed to be references to the securities which the Holders would be entitled to
receive in exchange for Registrable Securities under any such merger,
consolidation or reorganization; provided, however, that the provisions of this
Agreement shall not apply in the event of any merger, consolidation or
reorganization in which the Company is not the surviving corporation if the
Holders of Registrable Securities are entitled to receive in exchange therefor
(i) cash or (ii) securities of the acquiring corporation which may be
immediately sold to the public without registration under the Act.

     Section 14.  Miscellaneous.

of any such breach or default, or an acquiescence therein, or in any similar
breach or default occurring thereafter; nor shall any waiver of any single
breach or default be deemed a waiver of any other breach or, default theretofore

                     PHOENIX REGISTRATION RIGHTS AGREEMENT
                     -------------------------------------


     THIS PHOENIX REGISTRATION RIGHTS AGREEMENT (this "Agreement") is made as of
May 19, 1999 by and between Millitech Corporation, a Massachusetts corporation
(the "Company"), and Phoenix Leasing Incorporated, a California corporation
("Phoenix").

     WHEREAS, Phoenix has agreed to loan money to the Company pursuant to the
Senior Loan and Security Agreement No. 6240, dated as of May 19, 1999 (the "Loan
Agreement");

     WHEREAS, in connection with the Loan Agreement, the Company has issued
Phoenix warrants to purchase 44,445 shares (the "Warrant Shares") of Class E
Preferred Stock, par value $.01 per share, of the Company pursuant to a Warrant
to Purchase Shares of Class E Preferred Stock (the "Class E Warrant") of even
date herewith; and

     WHEREAS, as contemplated by the Class E Warrant, the parties desire to
enter into this Agreement to grant Phoenix certain rights with respect to the
Warrant Shares;

     NOW THEREFORE, in consideration of the transactions contemplated by the
Loan Agreement and other good and valuable consideration, the receipt and
sufficiency of which are acknowledged, the parties hereto agree as follows:

     Section 1.  Certain Definitions.  As used in this Agreement, the following
     -------------------------------
terms shall have the following meanings:

     "Act" means the Securities Act of 1933, as amended.

     "Commission" shall mean the Securities and Exchange Commission or any other
federal agency at the time administering the Act.

     "Holder" shall mean Phoenix or any assignee under Section 7 hereof who
holds outstanding Registrable Securities which have not been sold to the public.

     "Initial Public Offering" shall mean the effective date of a registration
statement under the Act in connection with the initial public offering of the
Company's securities for its own account.

     "1934 Act" shall mean the Securities Exchange Act of 1934, as amended.

     "Other Shareholders" shall mean any holders of securities of the Company
who are entitled, by agreement with the Company, to have securities included in
a registration of securities of the Company.

     "Registrable Securities" shall mean (i) the shares of the Company's common
stock ("Common Stock") issuable upon conversion of the Warrant Shares, (ii) any
Common Stock
<PAGE>

issued as a dividend or other distribution with respect to, or in exchange or in
replacement of, such Warrant Shares or Common Stock, and (iii) any Common Stock
issuable upon conversion, exercise or exchange of convertible securities,
warrants, options or similar rights issued as a dividend or other distribution
with respect to, or in exchange or in replacement of, such Warrant Shares or
Common Stock.

     The terms "register", "registered" and "registration" shall refer to a
registration effected by preparing and filing a registration statement in
compliance with the Act and applicable rules and regulations thereunder, and the
declaration or ordering of the effectiveness of such registration statement.

     "Registration Expenses" shall mean all expenses incurred by the Company in
connection with a registration, including without limitation all registration
and filing fees, printing expenses, fees and disbursements of counsel for the
Company, blue sky fees and expenses, fees and disbursements of a single counsel
for all the selling Holders and other security holders for a "due diligence"
examination of the Company, and the expense of any special audits incident to or
required by any such registration (but excluding the compensation of regular
employees of the Company, which shall be paid in any event by the Company).

     Section 2.  Company Registration.
     --------------------------------

     (a) If 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 a registration relating
solely to a Commission Rule 145 transaction, or a registration on any
registration form which does not permit secondary sales or does not include
substantially the same information as would be required to be included in a
registration statement covering the sale of Registrable Securities, the Company
will:

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

         (ii)  include in such registration and in any underwriting involved
therein, all the Registrable Securities specified in a written request or
requests, made by any Holder within 15 days after receipt of the written notice
from the Company described in clause (i) above, except as set forth in Section
2(b).  Such written request may specify all or a part of a Holder's Registrable
Securities be included in the Company's registration.

     (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(a)(i).  In such event the right of any Holder to registration pursuant to
Section 2 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 Shareholders distributing their securities through such underwriting)
enter into an underwriting agreement in customary form with the underwriter or
underwriters selected for underwriting by the Company.

                                       2
<PAGE>

Notwithstanding any other provision of Section 2, if the underwriter
determines that marketing factors require a limitation on the number of shares
to be underwritten, and (a) if such registration is the Initial Public Offering,
the underwriter may (subject to the allocation priority set forth below) exclude
from such registration and underwriting some or all of the Registrable
Securities which would otherwise be underwritten pursuant to the notice
described herein, and (b) if such registration is other than the Initial Public
Offering, the underwriter may (subject to the allocation priority set forth
below) limit the number of Registrable Securities to be included in the
registration and underwriting to not less than fifty percent (50%) of the
securities included therein (based on aggregate market values). The Company
shall so advise all holders of securities requesting registration, and the
number of shares of securities that are entitled to be included in the
registration and underwriting shall be allocated in the following manner. The
securities of the Company held by officers and directors of the Company (other
than Registrable Securities) shall be excluded from such registration and
underwriting to the extent required by such limitation, and, if a limitation on
the number of shares is still required, the number of shares that may be
included in the registration and underwriting shall be allocated among all such
Holders and Other Shareholders in proportion, as nearly as practicable, to the
respective amounts of Registrable Securities and other securities which they had
requested to be included in such registration at the time of filing the
registration statement, except that Registrable Securities held by the Other
Shareholders shall be the last to be limited. If any Holder of Registrable
Securities or any officer, director or Other Shareholder disapproves of the
terms of any such underwriting, he may elect to withdraw therefrom by written
notice to the Company and the underwriter. Any Registrable Securities or other
securities excluded or withdrawn from such underwriting shall be withdrawn from
such registration.

     Section 3.  Expenses of Registration.  All Registration Expenses incurred
     ------------------------------------
in connection with any registration pursuant to Section 2 shall be borne by the
Company.

     Section 4.  Registration Procedures.  In the case of each registration
     -----------------------------------
effected by the Company pursuant to this Agreement, the Company will keep each
Holder advised in writing as to the initiation of each registration and as to
the completion thereof.  At its expense, the Company will:

     (a) Prepare and file with the Commission a registration statement covering
the Registrable Securities requested to be registered as expeditiously as
reasonably possible and keep such registration effective for a period of nine
months; provided, however, that (i) such nine-month period shall be extended for
a period of time equal to the period the Holder refrains from selling any
securities included in such registration in accordance with the provisions of
Section 8; and (ii) in the case of any registration of Registrable Securities on
Form S-3 which are intended to be offered on a continuous or delayed basis, such
nine-month period shall be extended, if necessary, to keep the registration
statement effective until all such Registrable Securities are sold, provided
that Rule 415, or any successor rule under the Act, permits an offering on a
continuous or delayed basis, and provided further that applicable rules under
the Act governing the obligation to file a post-effective amendment permit, in
lieu of filing a post-effective amendment which (y) includes any prospectus
required by Section 10(a)(3) of the Act or (z) reflects facts or events
representing a material or fundamental change in the information set

                                       3
<PAGE>

forth in the registration statement, the incorporation by reference of
information required to be included in (y) and (z) above to be contained in
periodic reports filed pursuant to Section 13 or 15(d) of the Exchange Act in
the registration statement;

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

     (c) Use its best efforts to register and qualify the securities covered by
such registration statement under such other securities or Blue Sky laws of such
jurisdictions as shall be reasonably appropriate for the distribution of the
securities covered by the registration statement, provided that the Company
shall not be required in connection therewith or as a condition thereto to
qualify to do business or to file a general consent to service of process in any
such states or jurisdictions;

     (d) Provide a transfer agent for the Common Stock no later than the
effective date of the first registration of any Registrable Securities;

     (e) Otherwise use its best efforts to comply with all applicable rules and
regulations of the Commission;

     (f) Use its best efforts to cause all the Registrable Securities either (i)
to be listed on a national securities exchange (if the Registrable Securities
are not already so listed) and on each additional national securities exchange
on which similar securities issued by the Company are then listed, if the
listing of the Registrable Securities is then permitted under the rules of such
exchange, or (ii) to secure designation of all the Registrable Securities as a
NASDAQ "national market system security" within the meaning of Rule 11Aa2-1 of
the Commission or, failing that, to secure listing on NASDAQ for the Registrable
Securities and, without limiting the generality of the foregoing, to arrange for
at least two (2) market makers to register as such with respect to Registrable
Securities with the National Association of Securities Dealers, Inc.;

     (g) Enter into such customary agreements (including an underwriting
agreement in customary form) and take such other actions as sellers of
Registrable Securities shall reasonably request in order to expedite or
facilitate the disposition of such Registrable Securities;

     (h) In the case of an underwritten offering, on the date of delivery of the
Registrable Securities sold pursuant thereto, cause to be delivered to the
selling Holders and the underwriters, opinions of counsel for the Company, which
counsel and opinions (in form, scope and substance) shall be reasonably
satisfactory to counsel for the underwriters and counsel for the selling
Holders, covering the matters customarily covered in opinions given to
underwriters in primary underwritten public offerings.  At the time of delivery
of any Registrable Securities sold pursuant to an underwritten offering, the
Company shall cause to be delivered to the selling Holders and the underwriters
a letter from the Company's independent public accountants, addressed to the
underwriters and the selling Holders, stating that they are independent public
accountants within the meaning of the Act and the applicable published rules and
regulations of the Commission thereunder, and otherwise in customary form and
covering such financial and accounting matters

                                       4
<PAGE>

as are customarily covered by letters of the independent public accountants
delivered in connection with underwritten public offerings;

     (i) Make available for inspection by any seller of Registrable Securities,
by any underwriter participating in any disposition to be effected pursuant to
such registration statement and by any attorney, accountant or other agent
retained by any such seller or any such underwriter, all pertinent financial and
other records and pertinent corporate documents and properties of the Company
and cause all of the Company's officers, directors and employees to supply all
information reasonably requested by any such seller, underwriter, attorney,
accountant or agent in connection with such registration statement; in each case
as permitted by law and contractual confidentiality restrictions;

     (j) Permit any Holder of Registrable Securities which Holder, in the sole
and exclusive judgment, exercised in good faith, of such Holder, might be deemed
to be a controlling person of the Company (within the meaning of the Act or the
1934 Act) to participate in the preparation of such registration statement and
to request the insertion therein of material, furnished to the Company in
writing, which in the judgment of such controlling Holder should be included and
which is reasonably acceptable to the Company;

     (k) Use every reasonable effort to prevent the issuance of any stop order
suspending the effectiveness of such registration statement or of any order
preventing or suspending the use of any preliminary prospectus and, if any such
order is issued, to obtain the lifting thereof at the earliest reasonable time;
and

     (l) Make such representations and warranties to the selling Holders and the
underwriters as are customarily made by issuers to underwriters and selling
Holders, as the case may be, in underwritten public offerings.

     Section 5.  Indemnification.
     ---------------------------

     (a) The Company will indemnify each Holder, each of its officers, directors
and partners, and each person who controls such Holder, with respect to which
registration, qualification or compliance has been effected pursuant to this
Agreement, and each underwriter, if any, and each person who controls any
underwriter (within the meaning of the Act and the rules and regulations
thereunder) against all claims, losses, damages and liabilities (or actions in
respect thereof) arising out of or based on any untrue statement (or alleged
untrue statement) of a material fact contained in any registration statement,
prospectus, offering circular or other document incident to any such
registration, qualification or compliance, 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 not misleading, or any violation by the
Company of the Act or any rule or regulation thereunder 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 who
controls such Holder, each such underwriter and each person who controls any
such underwriter, for any legal and other expenses reasonably incurred in
connection with

                                       5
<PAGE>

investigating and 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 from or is based on
any untrue statement or omission or alleged untrue statement or omission based
upon written information furnished to the Company by such Holder or underwriter
and stated to be specifically for use therein.

     (b) Each Holder will, if Registrable Securities held by it are included in
the securities as to which such registration, qualification or compliance is
being effected, and each Other Shareholder who has the right to register its
securities pursuant to this Agreement will be required by the Company to,
indemnify the Company, each of its directors and officers and 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
the Act and the rules and regulations thereunder) each other such Holder and
Other Shareholder and each of their officers, directors and partners, and each
person who controls such Holder or Other Shareholder, against all claims,
losses, damages and liabilities (or actions in respect thereof) arising out of
or based on any untrue statement (or alleged untrue statement) of a material
fact contained if any such registration statement, prospectus, offering circular
or other document, or any omission (or alleged omission) to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and will reimburse the Company and such Holders, Other
Shareholders, directors, officers, partners, persons, underwriters or
controlling 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 such Holder or Other Shareholder and stated to be
specifically for use therein; provided, however, that the obligations of such
Holders and Other Shareholders hereunder shall be limited to an amount equal to
the proceeds to each such Holder or Other Shareholder of securities sold as
contemplated herein.

     (c) Each party entitled to indemnification under this Section 5 (the
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom, provided that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or any litigation resulting
therefrom, shall be approved by the Indemnified Party (whose approval shall not
unreasonably be withheld), and the Indemnified Party may participate in such
defense at such party's expense, and provided further that the failure of any
Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations under this Agreement.  No Indemnifying
Party, in the defense of any such claim or litigation, shall, except with the
consent of each Indemnified Party (which consent shall not unreasonably be
withheld), consent to entry of any judgment or enter into any settlement which
does not include as an unconditional term thereof the giving by the claimant or
plaintiff to such Indemnified Party of a release from all liability in respect
to such claim or litigation.  Each Indemnified Party shall furnish such
information regarding itself or the

                                       6
<PAGE>

claim in question as an Indemnifying Party may reasonably request in writing and
as shall be reasonably required in connection with defense of such claim and
litigation resulting therefrom.

     (d) In order to provide for just and equitable contribution to joint
liability under the Act in any case in which either (i) any Holder of
Registrable Securities exercising rights under this Agreement, or any
controlling person of any such Holder, makes a claim for indemnification
pursuant to this Section 5 but it is judicially determined (by the entry of a
final judgment or decree by a court of competent jurisdiction and the expiration
of time to appeal or the denial of the last right of appeal) that such
indemnification may not be enforced in such case notwithstanding the fact that
this Section 5 provides for indemnification in such case, or (ii) contribution
under the Act may be required on the part of any such selling Holder or any such
controlling person in circumstances for which indemnification is provided under
this Section 5; then, and in each such case, the Company and such Holder will
contribute to the aggregate losses, claims, damages or liabilities to which they
may be subject (after contribution from others) in such proportion so that such
Holder is responsible for the portion represented by the percentage that the
public offering price of its Registrable Securities offered by the registration
statement bears to the public offering price of all securities offered by such
registration statement, and the Company is responsible for the remaining
portion; provided, however, that, in any such case, (A) no such Holder of
         --------  -------
Registrable Securities will be required to contribute any amount in excess of
the net proceeds received from the sale of all such Registrable Securities
offered by it pursuant to such registration statement; and (B) no person or
entity guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Act) will be entitled to contribution from any person or entity who
was not guilty of such fraudulent misrepresentation.

     Section 6.  Information by Holder.  Each Holder of Registrable Securities,
     ---------------------------------
and each Other Shareholder holding securities included in any registration,
shall furnish to the Company such information regarding such Holder or Other
Shareholder and the distribution proposed by such Holder or Other Shareholder as
the Company may reasonably request in writing and as shall be reasonably
required in connection with any registration, qualification or compliance
referred to in Section 2 or 4.

     Section 7.  Transfer or Assignment of Registration Rights.  The rights to
     ---------------------------------------------------------
cause the Company to register the Registrable Securities granted by the Company
under Section 2 may be transferred or assigned by a Holder to a transferee or
assignee of any of the Holder's Registrable Securities, provided that the
Company is given written notice by a Holder at the time of or within a
reasonable time after said transfer or assignment, stating the name and address
of said transferee or assignee and identifying the securities with respect to
which such registration rights are being transferred or assigned and provided
further that the transferee or assignee of such rights assumes the obligations
of such Holder under this Agreement.

     Section 8.  "Market Stand-off" Agreement.  Each Holder agrees, if requested
     ----------------------------------------
by the Company and an underwriter of Common Stock (or other securities) of the
Company, not to sell or otherwise transfer or dispose of any Common Stock (or
other securities) of the Company held by it during the time period following the
effective date of a registration statement of the

                                       7
<PAGE>

Company filed under the Act requested by the underwriter, or in the absence of
such request, 90 days, provided that:

     (a) such agreement only applies to the first such registration statement of
the Company including securities to be sold on its behalf to the public in an
underwritten offering; and

     (b) all other Holders, Other Shareholders, principal officers and directors
of the Company enter into similar agreements.

     Such agreement shall be in writing in a form satisfactory to the Company
and such underwriter.  The Company may impose stop-transfer instructions with
respect to the shares (or securities) subject to the foregoing restriction until
the end of the restricted period.

     Section 9.  Reports Under the 1934 Act.  With a view to making available to
     --------------------------------------
the Holders the benefits of Rule 144 promulgated under the Act and any other
rule or regulation of the Commission that may at any time permit a Holder to
sell securities of the Company to the public without registration, the Company
agrees to use its best efforts to:

     (a) make and keep public information available, within the meaning of Rule
144, at all times after the effective date of (i) the first registration
statement covering an underwritten public offering filed by the Company or (ii)
registration by the Company under the 1934 Act;

     (b) following a public offering or a registration under the 1934 Act, file
with the Commission in a timely manner all reports and other documents required
of the Company under the Act and the 1934 Act; and

     (c) furnish to any Holder forthwith upon request a written statement by the
Company that it has complied with the reporting requirements of Rule 144 (at any
time after ninety (90) days after the effective date of said first registration
statement filed by the Company), and of the Act and the 1934 Act (at any time
after it has become subject to such reporting requirements), a copy of the most
recent annual or quarterly report of the Company, and such other reports and
documents filed by the Company with the Commission as may be reasonably
requested to permit any such holder to take advantage of any rule or regulation
of the Commission permitting the selling of any such securities without
registration.

     Section 10.  Mergers, Etc.  The Company shall not, directly or indirectly,
     --------------------------
enter into any merger, consolidation or reorganization in which the Company
shall not be the surviving corporation unless the proposed surviving corporation
shall, prior to such merger, consolidation or reorganization, agree in writing
to assume the obligations of the Company under this Agreement, and for that
purpose references hereunder to "Registrable Securities" shall be deemed to be
references to the securities which the Holders would be entitled to receive in
exchange for Registrable Securities under any such merger, consolidation or
reorganization; provided, however, that the provisions of this Agreement shall
not apply in the event of any merger, consolidation or reorganization in which
the Company is not the surviving corporation if

                                       8
<PAGE>

the Holders of Registrable Securities are entitled to receive in exchange
therefor (i) cash or (ii) securities of the acquiring corporation which may be
immediately sold to the public without registration under the Act.

     Section 11.  Miscellaneous.
     --------------------------

           -------------------
power or remedy accruing to any holder of any Registrable Securities, upon any
breach or default of the Company under this Agreement, shall impair any such
right, power or remedy of such holder nor shall it be construed to be a waiver
of any such breach or default, or an acquiescence therein, or in any similar
breach or default occurring thereafter; nor shall any waiver of any single
breach or default be deemed a waiver of any other breach or, default theretofore

                              PURCHASE AGREEMENT


     This Purchase Agreement dated June ____, 1988, (the "Agreement") is between

     ---------   -------------------
     Subject to the terms and conditions of this Agreement:

     1.1  The Loan.  On the Closing Date, MTDC agrees to lend to the Company the
          --------

Promissory Note in the principal amount of the Loan (the "Note"), in
substantially the form attached hereto as Schedule 1.1.

     1.2  The Stock Purchase Warrant.  On the Closing Date, the Company agrees
          --------------------------
to issue to MTDC a stock purchase warrant (the "Warrant") in substantially the
form set forth in Schedule 1.2 attached hereto to subscribe for and purchase
20,000 shares of the Company's Convertible Preferred Stock (the "Stock") at an

     Section 3.  Prepayment.
     ---------   ----------

          -------------------
the Closing Date, the Company may prepay the Loan at any time upon thirty (30)
days' prior written notice to the holder of the Note in whole or in part in any
multiple of $5,000 without premium or penalty; provided, however, if the Loan is
prepaid directly or indirectly with proceeds obtained from or in anticipation of
financing with a Lender other than MTDC, a premium of five percent (5%) of the
portion of the Loan so prepaid shall be due and payable to MTDC at the time of
the prepayment.  All prepayments shall be accompanied by interest on the amount

public accountants, and its unaudited balance sheet as of March 31, 1988,
together with a statement of income for the three-month period then ended,

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

filing with, any federal, state or other governmental authority or regulatory
body required for the execution, delivery and performance of this Agreement by
the Company have been, or prior to the Closing Date (as hereafter defined) will
have been, obtained or given. The Agreement constitutes, and the Note and the
Warrant when issued and delivered pursuant to this Agreement will constitute,

accordance with their terms. The Warrant Shares have been duly authorized and,
when issued upon exercise of the Warrant, will be

                                       4
<PAGE>

preferred stock of the Company have been duly reserved for issuance upon

          ------------------------
use the patents, patent rights, licenses, trade secrets, trademarks or trademark
rights, trade names or trade name rights or franchises, copyrights, inventions
and intellectual property rights used in its business as now conducted and as
now proposed to be conducted (a complete list of which is attached hereto as
Schedule 4.7). The business of the Company as now conducted and as now proposed
to be conducted does not and will not conflict with patents, patent rights,
licenses, trade secrets, trademarks, trademark rights, trade names or trade name

owned by other. The Company has no obligation to compensate any person,
corporation or other organization for the use of any patents or rights and has

     4.8  Litigation.  Except as described in Schedule 4.8, there is no action,
          ----------
proceeding or investigation pending or, to the best knowledge of the Company,
threatened which questions the validity of this Agreement or any action taken or
to be taken pursuant hereto or contemplated

                                       5
<PAGE>

hereby, or which might result, either in any case or in the aggregate, in any
material adverse change in the financial condition, business, or properties of
the Company and its Subsidiaries. The foregoing includes, without limiting its
generality, actions pending or threatened involving the prior employment of any
employees of the Company or their use of any information or technique allegedly
proprietary to their former employer.

     4.9  Leases.  All leases to which the Company is a party as lessee or
          ------
sublessee are valid and the Company is not in default thereunder, has not

          -----------------------
required by law to be filed have been duly filed and all taxes, fees and other
governmental charges shown thereon which are due and payable have been paid
(other than those being contested in good faith by appropriate proceedings
diligently conducted and with respect to which adequate reserves have been
established and no proceedings to foreclose have been commenced). The charges
and reserves on the books of the Company in respect of all income and other
taxes are adequate, and the Company knows of no additional assessment or any
basis therefore.

     4.11 Contracts.  Set forth in Schedule 4.11 or another Schedule to the
          ---------
Agreement attached hereto is a list of all contracts and agreements, written or
oral, which are of material importance to the business of the Company or any
Subsidiary, including without limitation all contracts and agreements (i) not
made in the ordinary course of business, (ii) having a value in excess of
$25,000, whether or not made in the ordinary course of business, but excluding
contracts for the purchase and sale of services and supplies made in the
ordinary course of business, (iii) with any labor union, (iv) for the future
purchase of fixed assets or for the future purchase of materials, supplies or
equipment in excess of normal operating requirements, (v) for the employment of
any officer, individual

                                       6
<PAGE>

employee or other person on a full-time basis or with any individual on a
consulting basis pursuant to which the Company or any Subsidiary has ongoing
obligations in excess of $10,000, (vi) setting forth bonus, pension, profit-
sharing, retirement, stock purchase, or stock option plans in effect with
respect to officers or employees, (vii) relating to the borrowing of money or to
the mortgaging, pledging or otherwise placing a lien on any assets of the
Company, (vii) constituting a guaranty of or pledge of property with respect to
any obligation for borrowed money or otherwise, (ix) constituting a lease or
agreement under which the Company is lessee or lessor of, or holds or operates,
or permits a third party to hold or operate, any real or personal property, (x)
constituting a license under which the Company sells or permits any third party
to sell any product or service, or (xi) under which the Company is obligated to
pay any broker's fees, finder's fees or any such similar fees, to any third
party. No such contract or agreement, and no other contract or agreement to
which the Company is a party or by which it is bound, contains any term which
now has, or as far as can be foreseen may have, a material adverse effect on the
financial condition, business or properties of the Company. The Company has
furnished to MTDC true, correct and complete copies of all such contracts and
agreements requested by MTDC.

     4.12 Transactions with Affiliates.  The only transactions in which the
          ----------------------------
Company and any person or entity controlling, controlled by or under common
control with the Company or any Subsidiary is presently engaged or proposes to
engage, directly or indirectly, are set forth in Schedule 4.12 attached hereto.
The terms and conditions of each such transaction are fair and reasonable to the
Company or the Subsidiary, as the case may be, and at least as favorable as
would obtain in a comparable transaction with an unaffiliated person or entity.

     4.13 Compliance with other Instruments, etc.  The Company is not in
          --------------------------------------
violation of any term of its charter or its bylaws, or of any agreement,
instrument, judgment, decree or order, or, to

                                       7
<PAGE>

the best knowledge of the Company, any statute, rule or governmental regulation
applicable to it. The execution, delivery and performance of this Agreement and
the taking of action contemplated hereby will not result in any violation of or
be in conflict with or constitute a default under any such term, or result in
the creation of any mortgage, lien, charge or encumbrance upon any of the
properties or assets of the Company pursuant to any such term.

     4.14 Disclosure.  Neither this Agreement nor any Schedule hereto, nor any
          -----------
certificate or other instrument furnished to MTDC by the Company, contains any
untrue statement of a material fact or omits to state a material fact necessary
in order to make the statements contained therein, in the light of the
circumstances under which they were made, not misleading. The Company has
furnished MTDC with a copy of its Five Year Business Plan dated January, 1988 as
well as supplementary memoranda outlining significant events occurring
subsequent to the date thereof (together the "Business Plan"), which set forth
the Company's current plans, forecasts and strategies. The materials presented
in the Business Plan do not contain any untrue statement of a material fact or
omit any material facts necessary to make the statements contained therein not
misleading; provided, however, that with respect to projections, the Company
represents and warrants only that such projections were prepared in good faith
on funding the basis of information and assumptions which the Company believes
to be reasonable. Without limiting the generality of the foregoing; (a) the
Company has no reason to believe that the Company will be unable to meet the
projections appearing in such Business Plan; (b) no employee or consultant of
the Company, the loss of whose services could materially and adversely affect
the Company or the business or prospects of the Company, has left the employ of
the Company, has given any indication that he or she intends to do so or is
considering doing so, or is being terminated; and (c) there has been no
discovery, change or development in the development, design, manufacture or
marketing of any product or proposed

                                       8
<PAGE>

product of the Company or any product that is or may be competitive with any
such product or of any new or improved materials, products or processes useful
in the business or proposed business of the Company to which an informed
investor in the Company would attach importance in its decision to make an
investment in the Company. There is no fact known to the Company relating to the
business, affairs, operation, condition or prospects of the Company materially
adversely affecting the same which has not been disclosed to MTDC in writing by
the Company.

     4.15 Brokers.  No finder, broker, agent, financial adviser or other
          -------
intermediary has acted on behalf of the Company in connection with the
negotiation or consummation of this Agreement or any of the transactions
contemplated hereby.

     4.16 ERISA.  The Company has not incurred any accumulated funding
          ------
deficiency within the meaning of the Employee Retirement Income Security Act of
1974 ("ERISA") nor has it incurred any liability to the Pension Benefit Guaranty
Corporation established under ERISA (or any successor thereto) in connection
with any employee pension benefit plan established or maintained by it, and
there have been no "reportable events" or "prohibited transactions" with respect
to any such plan, as those terms are defined in Section 4043 of ERISA and
Section 4975 of the Internal Revenue Code of 1954, as amended, respectively.

     Section 5.  Representations and Warranties of MTDC.
     ---------   --------------------------------------

effectiveness of such registration statement;

Securities, the Company shall, each such time, promptly give each Holder written

Company shall use its best efforts to cause to be registered under the

in such offering exceeds the amount of securities that the underwriters
reasonably believe compatible with the success of the offering, the Company
shall only be required to include in the offering so many of the securities of
the selling Holders as the underwriters believe will not jeopardize the success
of the offering (the securities so included to be apportioned pro rata among all
selling stockholders according to the total amount of securities owned by them.

registration statement with respect to such Registrable Securities and use its
best efforts to cause such registration statement to become and remain

shall in no event be obligated to cause any such registration to remain
effective for more than ninety (90) days.

     (b)  Prepare and file with the SEC such amendments and supplements to such
registration statement and the prospectus used in connection with such

to facilitate the disposition of Registrable Securities owned by them.

     (d)  Use its best efforts to register and qualify the securities covered by
such registration statement under such other securities or Blue Sky laws of such
jurisdiction as shall be reasonably appropriate for the distribution of the
securities covered by the registration statement, provided that the Company
shall not be required in connection therewith or as a condition thereto to
qualify to do business or to file a general consent to service of process in any
such states or jurisdictions, and further provided that (anything in this
Agreement to the contrary notwithstanding with respect to the

                                       23
<PAGE>

bearing of expenses) if any jurisdiction in which the securities are to be
qualified shall require that expenses incurred in connection with the
qualification of the securities in that jurisdiction be borne by selling
shareholders, then such expenses shall be payable by selling shareholders pro
rata, to the extent required by such jurisdiction.

     9.4  Furnish Information.  It shall be a condition precedent to the
          -------------------
obligations of the Company to take any action pursuant to Section 9 that the
Holders shall furnish to the Company such information regarding themselves, the
Registrable Securities held by them, and the intended method of disposition of
such securities as the Company shall reasonably request and as shall be required
in connection with the action to be taken by the Company.

     9.5  Indemnification.  In the event any Registrable Securities are included
          ---------------
in a registration statement under Section 9:

     (a)  To the extent permitted by law, the Company will indemnify and hold
harmless each Holder requesting or joining in a registration, any underwriter
(as defined in the Securities Act) for it, and each person, if any, who controls
such underwriter within the meaning of the Securities Act, against any losses,
claims, damages, or liabilities, joint or several, to which they may become
subject under the Securities Act or otherwise, insofar as such losses, claims,
damages, or liabilities (or actions in respect thereof) arise out of or are
based on any untrue or alleged untrue statement of any material fact contained
in such registration statement, including any preliminary prospectus or final
prospectus contained therein or any amendments of supplements thereto, or arise
out of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein, or necessary to make the statements
therein not misleading or arise out of any violation by the Company of any rule
or regulation promulgated under the Securities Act applicable to the Company and
relating to action or inaction required of the Company in connection with any
such registration;

and will reimburse each such Holder, such underwriter, or controlling person for
any legal or other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage, liability, or action;
provided, however, that the indemnity agreement contained in this subsection
9.7(a) shall not apply to amounts paid in settlement of any such loss, claim,
damage, liability, or action if such settlement is effected without the consent
of the Company (which consent shall not be unreasonably withheld) nor shall the
Company be liable in any such case for any such loss, claim, damage, liability,
or action to the extent that it arises out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged omission made in
connection with such registration statement, preliminary prospectus, final
prospectus, or amendments or supplements thereto, in reliance upon and in
conformity with written information furnished expressly for use in connection
with registration by any such Holder, underwriter, or controlling person.

     (b)  To the extent permitted by law, each Holder requesting or joining in a
registration will indemnify and hold harmless the Company, each of its
directors, each of its officers who have signed the registration statement, each
person, if any, who controls the Company within the meaning of the Securities
Act, and each agent and any underwriter for the Company (within the meaning of
the Securities Act) against any losses, claims, damages, or liabilities to which
the Company or any such director, officer, controlling person, agent, or
underwriter may become subject, under the Securities Act or otherwise, insofar
as such losses, claims, damages, or liabilities (or actions in respect thereto)
arise out of or are based upon any untrue statement or alleged untrue statement
of any material fact contained in such registration statement, including any
preliminary prospectus or final prospectus contained therein or any amendments
or supplements thereto, or arise out of or are based upon the omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, in each case to the
extent, but

                                       25

only to the extent, that such untrue statement or alleged untrue statement or
omission or alleged omission was made in such registration statement,
preliminary or final prospectus, or amendments or supplements thereto, in
reliance upon and in conformity with written information furnished by such
Holder expressly for use in connection with such registration; and each such
Holder will reimburse any legal or other expenses reasonably incurred by the
Company or any such director, officer, controlling person, agent, or underwriter
in connection with investigating or defending any such loss, claim, damage,
liability, or action; provided, however, that the indemnity agreement contained
in this subsection 9.7(b) shall not apply to amounts paid in settlement of any
such loss, claim, damage, liability, or action if such settlement is effected
without the consent of such Holder (which consent shall not be unreasonably
withheld).

     (c)  Promptly after receipt by an indemnified party under this subsection
of notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against any indemnifying party under this
subsection, notify the indemnifying party in writing of the commencement thereof
and the indemnifying party shall have the right to participate in, and, to the
extent the indemnifying party so desires, jointly with any other indemnifying
party similarly notified, to assume the defense thereof with counsel mutually
satisfactory to the parties. The failure to notify an indemnifying party
promptly of the commencement of any such action, if and only if prejudicial to
his ability to defend such action, shall relieve such indemnifying party of any
liability to the indemnified party under this subsection, but the omission so to
notify the indemnifying party will not relieve him of any liability that he may
have to any indemnified party otherwise than under this Section 9.7.

     9.6  Termination of the Company's Obligations.  The Company shall have no
          ----------------------------------------
obligation pursuant to Section 9.2 with respect to any request or requests made
by any Holder more than seven

                                       26
<PAGE>

(7) years after the effective date of the first registration statement filed by
the Company under the Securities Act.

     9.7  Reports Under Securities Exchange Act of 1934.  With a view to making
          ---------------------------------------------
available to the Holders the benefits of Rule 144 promulgated under the
Securities Act and any other rule or regulation of the SEC that may at any time
permit a Holder to sell securities of the Company to the public without
registration, the Company agrees to use its best efforts to:

     (a)  make and keep public information available, as those terms are
understood and defined in Rule 144, at all times subsequent to ninety (90) days
after the effective date of the first registration statement covering an
underwritten public offering filed by the Company;

     (b)  file with the SEC in a timely manner all reports and other documents
required of the Company under the Securities Act and the Securities Exchange Act
of 1934, as amended (the "Exchange Act"); and

     (c)  furnish to any Holder so long as such Holder owns any Registrable
Securities forthwith upon request a written statement by the Company that it has
complied with the reporting requirements of Rule 144 and of the Securities Act
and the Exchange Act, a copy of the most recent annual or quarterly report of
the Company, and such other reports and documents so filed by the Company as may
be reasonably requested in availing any Holder of any rule or regulation of the
SEC permitting the selling of any such securities without registration.

     9.8  Transfer of Registration Rights.  The registration rights of MTDC
          -------------------------------
under this Section 9 may be transferred to any transferee of Registrable
Securities provided, however, that the Company is given written notice by MTDC
at the time of such transfer stating the name and address of the transferee and
identifying the securities with respect to which the rights under this Section 9
are being transferred.

     9.9  Legends; Stop Transfer.
          ----------------------

     (a)  All certificates for shares issuable upon exercise of the Warrant (the
"Warrant Shares") shall bear substantially the following legend:

          "These securities have not been registered under the Securities Act of
     1933. They may not be sold, offered for sale, pledged or hypothecated in
     the absence of an effective registration statement as to the securities
     under said Act or an opinion of counsel satisfactory to the Company that
     such registration is not required."

     (b)  The certificates for Warrant Shares shall also bear any legend
required by any applicable state law.

     (c)  In addition, the Company may make a notation regarding the
restrictions on transfer of Warrant Shares shall be transferred on the books of
the Company only if transferred or sold pursuant to an effective registration
statement under the Securities Act covering such shares or pursuant to an
exemption from such registration.

     9.10 Lockup Agreement.  In consideration for the Company agreeing to its
          ----------------
obligations under this Section 9, MTDC agrees in connection with any
registration of the Company's securities that, upon the request of the Company
or the underwriters managing any underwritten offering of the Company's
securities, not to sell, make any short sale of, loan, grant any option for the
purchase of, or otherwise dispose of any Registrable Securities (other than
those included in the registration) without the prior written consent of the
Company or such underwriters, as the case may be, for such period of time (not
to exceed ninety (90) days) from the effective date of such registration as the
Company or the underwriters may specify.

     Section 10.  Events of Default.
     ----------   -----------------

     The occurrence of any one or more of the following events shall constitute
an event of default by the Company under this Agreement:

     10.1 Default by the Company in any principal or interest payment on the
Note when due.

                                       28
<PAGE>

     10.2 Default by the Company in the performance or observance of the

     10.3 Default by the Company in the performance or observance of any of the

if such default remains unremedied for thirty (30) days after receipt by the
Company of written notice from MTDC.

     10.4 Default by the Company or any Subsidiary in the payment when due of
the principal of any other indebtedness for borrowed money or default in any
other obligation relating to such indebtedness if the result thereof has been to
cause the holder of such indebtedness to declare the same due and payable.

     10.5 Any written representation or warranty made by the Company in this
Agreement or in connection therewith or any financial statement, report,
schedule, or certificate furnished by the Company or any of its officers or
accountants to MTDC during the term of this Agreement shall prove to have been
incorrect as of its date in any material respect.

     10.6 The Company or any Subsidiary shall file a voluntary petition in
bankruptcy or any petition or answer seeking for itself any reorganization,
readjustment, arrangement, composition or similar relief; or shall commence a
voluntary case under the federal bankruptcy laws; or shall admit in writing its
insolvency or its inability to pay its debts as they become due; or shall make
an assignment for the benefits of creditors; or shall apply for, consent to or
acquiesce in the appointment of, or the taking of possession by, a trustee,
receiver, custodian or similar official or agent of the Company or any
Subsidiary or of substantially all of its property; or a trustee, receiver,
custodian or similar official or agent of the Company or any Subsidiary or of
substantially all of its property; or a trustee, receiver, custodian or similar
official or agent shall be appointed for the Company or any Subsidiary or for

<PAGE>

60 days; or a petition seeking reorganization, readjustment, arrangement,
composition, or other similar relief as to the Company or any Subsidiary under
the federal bankruptcy laws or any similar law for the relief of debtors shall
be brought against the Company or any Subsidiary and shall be consented to by it
or shall remain undismissed for sixty days.

     Upon the occurrence of any event of default, the Note will immediately
become due and payable without demand, notice, or protest, all of which are
hereby expressly waived. In addition, the Note will similarly immediately become
due and payable in the event that the Company redeems any of its preferred stock
for a consideration in excess of $40,000 in any twelve month period. Thereafter,
the holder of the Note may proceed to protect and enforce its rights, at law, in
equity or otherwise, against the Company and any indorser or guarantor of the
Company's obligations to the holder of the Note, either jointly or severally,
and may proceed to liquidate and realize upon any of its collateral, if any, in
accordance with the rights of a secured party under the Uniform Commercial Code
or any other applicable law.

     Section 11.  Reimbursement for Expenses.
     ----------   --------------------------

     Whether or not the transactions contemplated hereby shall be consummated,
the Company shall reimburse MTDC for all reasonable out-of-pocket expenses,
including without limitation all reasonable attorneys' fees and disbursements,
incurred in connections with the making and collection of the Loan or the
exercise of the Warrant and the preparation of this Agreement and any amendments
hereto or waivers of the provisions hereof. Said expenses shall include all
costs and expenses, legal or otherwise, incurred by MTDC in the exercise of any
of its rights, powers or privileges whether or not such action or proceeding
follows an event of default.

     Section 12.  Miscellaneous Provisions.

     12.1 Entire Agreement and Waivers.  This Agreement, the Note and the
          ----------------------------
Warrant together constitute the entire agreement between the Company and MTDC,
and no covenant, term, condition or other provision thereof nor any default in
connection therewith may be waived except by an instrument in writing signed by
MTDC and delivered to the Company. MTDC's failure to exercise or enforce any of
its rights, powers or privileges under this Agreement, the Note or the Warrant
shall not operate as a waiver thereof, and no waiver by MTDC of a breach of any
provision of this Agreement shall be deemed to be a waiver of any preceding or
subsequent breach of the same or any other provision hereof.

     12.2 Remedies Cumulative.  All remedies provided under this Agreement, the
          -------------------
Note and the Warrant or afforded by law shall be cumulative and available to

     12.3 Survival of Covenants.  All covenants, agreements, representations and
          ---------------------
warranties made herein and in certificates and Schedules delivered in connection
herewith shall be deemed material and relied on by MTDC, notwithstanding any
investigation made by MTDC or on its behalf, and shall survive the execution and
delivery of this Agreement, the Note and the Warrant. All such covenants,
agreements, representations and warranties shall bind and inure to the benefit
of the Company's and MTDC's successors and assigns, whether so expressed or not.

     12.4  Governing Law.  This Agreement, the Warrant and the Note shall be
           -------------
construed in accordance with the laws of the Commonwealth of Massachusetts.

     12.5 Assurance of Execution and Delivery of Additional Instruments.  The
          -------------------------------------------------------------
Company agrees to execute and deliver, or to cause to be executed and delivered,
to MTDC all such further instruments, and to do or cause to be done all such
further acts and things, as MTDC may reasonably request or as may be necessary
or desirable to effect further the purposes of this Agreement.

                                       31
<PAGE>

     12.6 Extension of Time.  Whenever any payment to be made under the Note
          -----------------
shall be due on a Saturday, Sunday or a public holiday under the laws of the
Commonwealth of Massachusetts, said payment may be made on the next succeeding
business day and such extension of time shall in such case be included in
computing interest in connection with said payment.

     12.7 Notices.  Any notices required or provided for under this Agreement
          -------
