Each Purchaser represents and warrants with respect to only itself that:

a. Investment Purpose.  Such Purchaser (i) is acquiring the Preferred Shares
and (ii) upon conversion of the Preferred Shares, will acquire the Conversion
Shares then issuable (the Preferred Shares and the Conversion Shares,
collectively, are referred to herein as the "Securities") for its own account
for investment only and not with a present view towards, or for resale in
connection with, the public sale or distribution thereof, except pursuant to
sales registered or exempted under the 1933 Act; provided, however, that by
making the representations herein, such Purchaser does not agree to hold any
Securities for any minimum or other specific term and reserves the right to
dispose of the Securities at any time in accordance with or pursuant to a
registration statement or an exemption under the 1933 Act.

b. Accredited Investor Status.  Such Purchaser is an "accredited investor" as
that term is defined in Rule 501(a)(3) of Regulation D under the 1933 Act.

c. Reliance on Exemptions.  Such Purchaser understands that the Securities
are being offered and sold to it in reliance on specific exemptions from the
registration requirements of the United States federal and state securities
laws and that the Company is relying upon the truth and accuracy of, and such
Purchaser's compliance with, the representations, warranties, agreements,
acknowledgments and understandings of such Purchaser set forth herein in
order to determine the availability of such exemptions and the eligibility of
such Purchaser to acquire the Securities.

d. Information.  Such Purchaser and its advisors, if any, have been furnished
with all materials relating to the business, finances and operations of the
Company and materials relating to the offer and sale of the Securities which
have been requested by such Purchaser.  Such Purchaser and its advisors, if
any, have been afforded the opportunity to ask questions of and receive
answers from the Company.  Neither such inquiries nor any other due diligence
investigations conducted by such Purchaser or its advisors, if any, or its
representatives shall modify, amend or affect such Purchaser's right to rely
on the Company's representations and warranties contained in this Agreement.
Purchaser understands that its investment in the Securities involves a high
degree of risk.  Purchaser has sought such accounting, legal, and tax advice
as it has considered necessary to make an informed investment decision with
respect to its acquisition of the Securities.

e. No Governmental Review.  Such Purchaser understands that no United States
federal or state agency or any other government or governmental agency has

2


passed on or made any recommendation or endorsement of the Securities or the
fairness or suitability of the investment in the Securities nor have such
authorities passed upon or endorsed the merits of the offering of the
Securities.

f. Transfer or Resale.  Such Purchaser understands that: (i) the Securities
have not been and are not being registered under the 1933 Act or any state
securities laws, and may not be offered for sale, sold, assigned or
transferred unless (A) they are offered, sold, assigned or transferred
pursuant to an effective registration statement under the 1933 Act, (B) such
Purchaser shall have delivered to the Company an opinion of counsel, in a
form and from counsel reasonably acceptable to the Company, to the effect
that such Securities to be sold, assigned or transferred may be sold,
assigned or transferred pursuant to an exemption from such registration, or
(C) such Purchaser provides the Company with reasonable assurance that such
Securities can be sold, assigned or transferred pursuant to Rule 144
promulgated under the 1933 Act (or a successor rule thereto) ("Rule 144");
(ii) any sale of the Securities made in reliance on Rule 144 may be made only
in accordance with the terms of Rule 144 and further, if Rule 144 is not
applicable, any resale of the Securities under circumstances in which the
seller (or the person through whom the sale is made) may be deemed to be an
underwriter (as that term is defined in the 1933 Act) may require compliance
with some other exemption under the 1933 Act or the rules and regulations of
the SEC thereunder; and (iii) neither the Company nor any other person is
under any obligation to register the Securities under the 1933 Act or any
state securities laws or to comply with the terms and conditions of any
exemption thereunder.

g. Legends.  Purchaser understands that the certificates or other instruments
representing the Preferred Shares and, until such time as the sale of the
Conversion Shares have been registered under the 1933 Act, the stock
certificates representing the Conversion Shares shall bear a restrictive
legend in substantially the following form (and a stop transfer order may be
placed against transfer of such stock certificates):

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS.
THE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BE OFFERED FOR
SALE, SOLD, TRANSFERRED, OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE
REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933,
AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS, OR AN OPINION OF COUNSEL, IN
A GENERALLY ACCEPTABLE FORM, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT
OR APPLICABLE STATE SECURITIES LAWS OR UNLESS SOLD PURSUANT TO RULE 144 UNDER
SAID ACT.

The legend set forth above shall be removed and the Company shall issue a
certificate without such legend to the holder of the Preferred Shares and the
Conversion Shares, upon which it is stamped, if, unless otherwise required by
state securities laws, (a) the sale of the Conversion Shares is registered
under the 1933 Act, (b) in connection with a sale transaction, such holder
provides the Company with an opinion of counsel, in a generally acceptable
form, to the effect that a public sale, assignment, or transfer of the
Preferred Shares and the Conversion Shares may be made without registration
under the 1933 Act, or (c) such holder provides the Company with reasonable
assurances that the Preferred Shares and the Conversion Shares can be sold
pursuant to Rule 144 without any restriction as to the number of securities
acquired as of a particular date that can then be immediately sold.

given by the Purchaser or any of its respective representatives or agents in
connection with this Agreement and the transactions contemplated hereby is
merely incidental to such Purchaser's purchase of the Securities.  The

prior offerings by the Company for purposes of the 1933 Act or any applicable
stockholder approval provisions.

m. Employee Relations.  Neither the Company nor any of its subsidiaries is

of the Disclosure Schedule, none of the Company's trademarks, trade names,
service marks, service mark registrations, service names, patents, patent

names, service marks, service mark registrations, trade secret, or other
similar rights of others. Except as set forth on Section 3(n) of the
Disclosure Schedule, there is no claim, action, or proceeding being made or
brought against, or to the Company's knowledge, being threatened against, the
Company or its subsidiaries regarding trademark, trade name, patents, patent
rights, invention, copyright, license, service names, service marks, service
mark registrations, trade secret, or other infringement, and the Company and

prudent and customary in the businesses in which the Company and its
subsidiaries are engaged.  Neither the Company nor any such subsidiary has
been refused any insurance coverage sought or applied for, and neither the
Company nor any such

9


subsidiary has any reason to believe that it will not be able to renew its
existing insurance coverage as and when such coverage expires or to obtain
similar coverage from similar insurers as may be necessary to continue its
business at a cost that would not materially and adversely affect the
condition, financial, or otherwise, or the earnings, business, or operations
of the Company and its subsidiaries, taken as a whole.

r. Regulatory Permits.  The Company and its subsidiaries possess all
certificates, authorizations, and permits issued by the appropriate federal,

effect on the Company and its subsidiaries taken as a whole, and neither the
Company nor any such subsidiary has received any notice of proceedings
relating to the revocation or modification of any such certificate,
authorization, or permits.

s. Internal Accounting Controls.  The Company and each of its subsidiaries
maintain a system of internal accounting controls sufficient to provide

conformity with generally accepted accounting principles and to maintain
asset accountability, (iii) access to assets is permitted only in accordance

intervals and appropriate action is taken with respect to any differences.

t. No Materially Adverse Contracts, Etc.  Neither the Company nor any of its
subsidiaries is subject to any charter, corporate, or other legal
restriction, or any judgment, decree, order, rule, or regulation which in the

properties, operations, financial condition, results of operations, or
prospects of the Company or its subsidiaries.  Neither the Company nor any of
its subsidiaries is a party to any contract or agreement which in the

unpaid and unreported taxes), and has paid all taxes and other governmental
assessments and charges that are material in amount, shown or determined to
be due on such returns, reports, and declarations, except those being
contested in good faith, and has set aside on its books amounts deemed
reasonably adequate for the payment of all taxes for periods subsequent to
the periods to which such returns, reports, or declarations apply.  There are
no unpaid taxes in any material amount claimed to be due by the taxing
authority of any jurisdiction, and the officers of the Company know of no
basis for any such claim, and there are no open years, examinations in
progress or

10


claims against it for federal, state or other taxes (including penalties and
interest) for any period or periods prior to the date hereof.

v. Certain Transactions.  Except as set forth on Section 3(v) of the
Disclosure Schedule and in the SEC Documents, and except for arm's length

from third parties and other than the grant of stock options disclosed on
Section 3(c) of the Disclosure Schedule, none of the officers, directors, or
employees of the Company is presently a party to any transaction with the
Company (other than for services as employees, officers, and directors),

property to or from, or otherwise requiring payments to or from any officer,
director, or such employee or, to the knowledge of the Company, any
corporation, partnership, trust, or other entity in which any officer,

of Conversion Shares issuable upon conversion of the Preferred Shares will

other stockholders of the Company.

in writing by the Purchaser. The business of the Company and its subsidiaries
shall not be conducted in violation of any law, ordinance, or regulation of
any governmental entity.

5.  PIGGYBACK REGISTRATION RIGHTS

a. If at any time the Company proposes to file with the SEC a Registration
Statement relating to an offering for its own account or the account of
others under the 1933 Act of any of its securities (other than on Form S-4 or
Form S-8 or their then equivalents relating to securities to be issued solely
in connection with any acquisition of any entity or business or equity
securities issuable in connection with stock option or other employee benefit
plans) the Company shall promptly send to the Purchaser written notice of the
Company's intention to file a registration statement and of such Purchaser's
rights under this Section 5(a) and, if within twenty (20) days after receipt
of such notice, such Purchaser shall so request in writing, the Company shall
include in such registration statement all or any part of the Conversion
Shares such Purchaser requests to be registered.  If an offering in
connection with which the Purchaser is entitled to registration under this
Section 5(a) is an underwritten offering, then such Purchaser whose
Conversion Shares are included in such registration statement shall, unless
otherwise agreed by the Company, offer and sell such Conversion Shares in an
underwritten offering using the same underwriter or underwriters and, subject
to the provisions of this Agreement, on the same terms and conditions as
other shares of Common Stock included in such underwritten offering.

b. If the registration referred to in Section 5(a) is to be an underwritten
public offering for the account of the Company and the managing
underwriter(s) advise the Company in writing, that in their reasonable good
faith opinion, marketing or other factors dictate that a limitation on the
number of shares of Common Stock which may be included in the registration
statement is necessary to facilitate and not adversely affect the proposed
offering, then the Company shall include in such registration: (i) first, all
securities the Company proposes to sell for its own account, (ii) second, up
to the full number of securities proposed to be registered for the account of
the holders of securities entitled to inclusion of their securities in the
registration statement by reason of demand registration rights, and (iii)
third, the securities requested to be registered by the Purchaser and other
holders of securities entitled to participate in the registration, drawn from
them pro rata based on the number each has requested to be included in such
registration.

6.	TRANSFER AGENT INSTRUCTIONS

16


The Company shall issue Purchaser, and cause any subsequent transfer agent to
issue certificates in the name of each Purchaser or its respective
nominee(s), for the Conversion Shares in such amounts as specified from time
to time by each Purchaser to the Company upon conversion of the Preferred
Shares.  Prior to sale of the Conversion Shares and pursuant to an effective
registration statement under the 1933 Act, all such certificates shall bear
the restrictive legend specified in Section 2(g) of this Agreement.  The
Company warrants that no instruction other than the Irrevocable Transfer
Agent Instructions referred to in this Section 6 and stop transfer
instructions to give effect to Section 2(g) hereof (in the case of the
Conversion Shares, prior to the sale of the Conversion Shares pursuant to an
effective registration statement under the 1933 Act) will be given by the
Company to its transfer agent and that the Securities shall otherwise be
freely transferable on the books and records of the Company as and to the
extent provided in this Agreement.  If an Purchaser provides the Company with
an opinion of counsel, in form reasonably acceptable to the Company, to the
effect that a public sale, assignment or transfer of Securities may be made
without registration under the 1933 Act or the Purchaser provides the Company
with reasonable assurances that the Securities can be sold pursuant to Rule
144 without any restriction as to the number of securities acquired as of a
particular date that can then be immediately sold, the Company shall permit
the transfer, and, in the case of the Conversion Shares, promptly instruct
its transfer agent to issue one or more certificates, in such name and in
such denominations as specified by such Purchaser and without any restrictive
legend.  The Company acknowledges that a breach by it of its obligations
hereunder will cause irreparable harm to the Purchaser by violating the
intent and purpose of the transaction contemplated hereby.  Accordingly, the
Company acknowledges that the remedy at law for a breach of its obligations
under this Section 6 will be inadequate and agrees, in the event of a breach
or threatened breach by the Company of the provisions of this Section 6, that
the Purchaser shall be entitled, in addition to all other available remedies,
to an order and/or injunction restraining any breach and requiring immediate
issuance and transfer, without the necessity of showing economic loss and
without any bond or other security being required.

7.	CONDITIONS TO THE COMPANY'S OBLIGATION TO SELL.

Massachusetts, irrespective of the choice of law provisions thereof.  The
parties agree that any action brought by one party against the other shall be
in any appropriate state court or any federal Court located in the County
where the party against whom the action is brought is principally located,
and both parties agree that such courts shall have exclusive jurisdiction of
such case or controversy arising under or in connection with this Agreement
and shall be a proper forum in which to adjudicate such case or controversy.
The parties consent to the jurisdiction of such courts.  EACH PARTY HEREBY
IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY
TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION HEREWITH
OR ARISING OUT OF THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY.

b. Counterparts.  This Agreement may be executed in two or more identical
counterparts, all of which shall be considered one and the same agreement and
shall become effective when counterparts have been signed by each party and
delivered to the other party; provided that a facsimile signature shall be
considered due execution and shall be binding upon the signatory thereto with
the same force and effect as if the signature were an original, not a
facsimile signature.

and shall not form part of, or affect the interpretation of, this Agreement.

d. Severability.  If any provision of this Agreement shall be invalid or
unenforceable in any jurisdiction, such invalidity or unenforceability shall
not affect the validity or enforceability of the remainder of this Agreement
in that jurisdiction or the validity or enforceability of any provision of
this Agreement in any other jurisdiction.

oral or written agreements between each Purchaser, the Company, their

of this Agreement may be amended or waived other than by an instrument in
writing signed by the Company and the holders of at least 66 2/3% of the
Preferred Shares then outstanding.  No such amendment shall be effective to
the extent that it applies to less than all of the holders of the Preferred
Shares then outstanding.  No consideration shall be offered or paid to any
person to amend or consent to a waiver or modification of any provision of
any of the Transaction Agreements or the Certificate of Designations unless
the same

19


consideration also is offered to all of the parties to the Transaction
Agreements or holders of Preferred Shares, as the case may be.

or permitted to be given under the terms of this Agreement must be in writing

of Designations) with respect to which the Company is in compliance with
Section 5 of the Certificate of Designations and Section 4(d) of this
Agreement.  A Purchaser may assign some or all of its rights hereunder
without the consent of the Company; provided, however, that such transferee
will not be deemed a Purchaser hereunder unless such transferee has acquired
at least 50 shares of Preferred Stock (as adjusted to reflect any stock
splits, reverse stock splits and similar capital events) and such transferee
has agreed in writing in form and substance reasonably satisfactory to the
Company to be bound by the applicable provisions of this Agreement.

Agreements, the Purchaser shall be entitled to pledge the Securities in
connection with a bona fide margin account or other loan secured by the
Securities.

of the parties hereto and their respective permitted successors and assigns,
and is not for the benefit of, nor may any provision hereof be enforced by,
any other person.

representations and warranties of the Company and the Purchaser contained in
Sections 2 and 3, and the agreements and covenants set forth in Sections 4,
5, 6 and 9, shall survive the Closing.  Each Purchaser shall be responsible
only for its own representations, warranties, agreements and covenants
hereunder.

j. Publicity.  The Company and each Purchaser shall have the right to approve
before issuance any press releases or any other public statements with
respect to the transactions contemplated hereby; provided, however, that the
Company shall be entitled, without the prior approval of any Purchaser, to
make any press release or other public disclosure with respect to such
transactions as the Company reasonably believes upon consultation with its
outside counsel is required by applicable law and regulations (although each
Purchaser shall be consulted by the Company in connection with any such press
release or other public disclosure prior to its release and shall be provided
with a copy thereof).

k. Further Assurances.  Each party shall do and perform, or cause to be done
and performed, all such further acts and things, and shall execute and
deliver all such other agreements, certificates, instruments and documents,
as the other party may reasonably request in order to carry out the intent
and accomplish the purposes of this Agreement and the consummation of the
transactions contemplated hereby.

l. Termination.  In the event that the Closing shall not have occurred with
respect to an Purchaser on or before five (5) Business Days from the date
hereof due to the Company's or such

21


Purchaser's failure to satisfy the conditions set forth in Sections 7 and 8
above (and the nonbreaching party's failure to waive such unsatisfied
condition(s)), the nonbreaching party shall have the option to terminate this
Agreement with respect to such breaching party at the close of business on
such date without liability of any party to any other party.

m. No Strict Construction.  The language used in this Agreement will be
deemed to be the language chosen by the parties to express their mutual
intent, and no rules of strict construction will be applied against any
party.

rights and remedies set forth in the Transaction Agreements and the
Certificate of Designations and all rights and remedies which such holders
have been granted at any time under any other agreement or contract and all
of the rights which such holders have under any law.  Any person having any
