accuracy of the representations of Purchaser in this Agreement, when such shares
of Common Stock are issued, such shares will be issued in compliance with all

to grant or issue, any options, warrants or similar rights to acquire or receive
any of the authorized but unissued shares of its capital stock of any class or
any securities convertible into shares of its capital stock of any class or any

     5.3  NO DEFAULTS. Except as set forth in SCHEDULE 5.3, neither the Company
nor any of its Subsidiaries, to its knowledge, is in violation of, or in default
under, nor has there been any waiver given with respect to, any term or
provision of any charter, by-law, mortgage, indenture, agreement, instrument,
statute, rule, law, regulation, judgment, decree, order, writ, or injunction
applicable to it, such that such violations and defaults in the aggregate could
reasonably be expected to result in any material adverse change in the business,
assets, properties, condition (financial or otherwise) or results of operations
of the Company and its Subsidiaries, taken as a whole, or materially adversely
affect the ability of the Company to perform in any material respect its
obligations under this Agreement. All Regulatory Approvals required by the
Company and its Subsidiaries to conduct their respective business as now
conducted by them have been obtained and are in full force and effect, and the
Company and its Subsidiaries are in compliance with the terms and requirements
of such Regulatory Approvals. Except as set forth on SCHEDULE 5.3 hereto, since
December 31, 2002, none of the Company or any of its Subsidiaries has received
any written notice or other written communication from any Governmental Entity
regarding (i) any revocation, withdrawal, suspension, termination or
modification of, or the imposition of any material conditions with respect to,
any Regulatory Approval, (ii) any violation of any law by the Company or any of
its Subsidiaries, or (iii) any other limitations on the conduct of business by
the Company or any of its Subsidiaries.

     5.4  BURDENSOME AND CONFLICTING AGREEMENTS AND CHARTER PROVISIONS. Neither
the execution or delivery of the Transaction Documents by the Company, nor the
offering, issuance and sale of the Securities by the Company, nor fulfillment
of, or compliance with, the terms and provisions of the Transaction Documents,
nor the issuance by the Company of shares of Common Stock upon exercise of the
Common Stock Warrants, will, except as set forth in SCHEDULE 5.4, conflict with,
or result in a breach of the terms, conditions or provisions of, or constitute a
default under, or result in any violation of, or result in the creation of any
lien upon any of the properties or assets of the Company or any of its
Subsidiaries, or require any consent, approval or other action by, or notice to,
or filing with, any court or administrative or governmental body or any other
Person or pursuant to the Certificate of Incorporation or by-laws of the Company
or the certificate of incorporation or by-laws of any of the Company's
Subsidiaries, any award of any arbitrator or any material agreement (including
any agreement with stockholders), instrument, order, judgment, decree, statute,
law, rule or regulation to which the Company or any of its Subsidiaries is
subject, except for such approvals or waivers as may be required in connection
with fulfillment of, or compliance with, the Certificate of Designation,
Investor Rights Agreement, Common Stock Warrants Issued to Preferred Holders and
Stockholders Agreement, which shall have been obtained by the Closing Date.

     5.5  TITLE TO ASSETS, ETC. The Company has good and marketable fee simple
title to the assets reflected on the balance sheet set forth on SCHEDULE 5.5
(the "ASSETS"). Except as set forth

                                       10
<Page>

in SCHEDULE 5.5, none of the Assets is subject to any encumbrances, except for
minor liens that in the aggregate are not substantial in amount, do not
materially detract from the value of the property or assets subject thereto or
interfere with the present use thereof and have not arisen other than in the
ordinary course of business. There are no pending or threatened condemnation
proceedings relating to any of the facilities of the Company. The real property
improvements (including leasehold improvements) and fixtures and equipment of
the Company are adequately insured and are structurally sound with no known
material defects. The facilities, fixtures and equipment of the Company are in
good operating condition and repair (except for ordinary wear and tear and any
defect for which the cost of repairing would not be material), are sufficient
for the operation of the Company's business as presently conducted and are in
conformity in all material respects with all applicable laws, ordinances,
orders, regulations and other requirements (including applicable zoning,
environmental, motor vehicle safety or standards, occupational safety and health
laws and regulations) relating thereto currently in effect, except where the
failure to conform would not have a material adverse effect on the business or
financial condition of the Company. The Assets are valued on the Company's books
at or below actual cost less an adequate and proper depreciation charge. The
Company has not depreciated any of the Assets on an accelerated basis or in any
other manner inconsistent with applicable Internal Revenue Service tax and
fiscal guidelines, if any.

     5.6  LEASES. Each of the Company and its Subsidiaries enjoy peaceful and
undisturbed possession of all leases material to them. All such leases are valid
and subsisting and are in full force and effect.

     5.7  CONTRACTS. Except as set forth in SCHEDULE 5.7, there is no contract,
agreement or understanding required to be described in or filed as an exhibit to
any Commission Documents that is not described in or filed as required by the
Securities Act or the Exchange Act, as the case may be. Except as set forth in
SCHEDULE 5.7, each such contract, agreement and understanding is valid and
binding and is in full force and effect and enforceable in accordance with its
terms (except as enforceability may be limited by applicable bankruptcy,
insolvency or similar laws affecting the enforcement of creditors' rights
generally or as may be limited by equitable principles relating to
enforceability), except in the case of such contracts, agreements or
understandings that are by their terms no longer in force or effect. Except as
set forth on SCHEDULE 5.7, (a) no approval or consent of, or notice to, any
Person is needed in order that such contract, agreement or understanding shall
continue in full force and effect in accordance with its terms without penalty,
acceleration or rights of early termination following the consummation of the
transactions contemplated by the Transaction Documents, other than such notices,
consents and approvals as have been obtained and (b) the Company and/or its
Subsidiaries are not in violation of, breach of, or default under any such
contract, agreement or understanding nor, to the Company's knowledge, is any
other party to any such contract, agreement or understanding.

the balance sheet of the Company and its consolidated Subsidiaries as at

cash flows of the Company and its consolidated Subsidiaries for the fiscal year
ended December 31, 2002, all certified by BDO Seidman LLP, including in each
case the related schedules and notes.

     All such financial statements (including any related schedules and notes)
have been prepared in accordance with generally accepted accounting principles
consistently applied, except to the extent set forth in the notes to such
financial statements. The balance sheets and the related schedules and notes
fairly present the financial condition of the Company and its

                                       11
<Page>

consolidated Subsidiaries as at the dates thereof and the net income and
stockholders' equity statements and the related schedules and notes fairly
present the results of the operations of the Company and its consolidated
Subsidiaries for the periods indicated. Except as set forth in SCHEDULE 5.8, the
Company has incurred no material liabilities since December 31, 2002, other than
those incurred in the ordinary course.

     Except as set forth in SCHEDULE 5.8, there has been no material adverse
change in the assets, business, prospects, properties, operations or condition,
financial or otherwise, of the Company and its Subsidiaries, taken as a whole,
since December 31, 2002.

     5.9  ACTIONS PENDING. There is no action, suit, investigation or proceeding
pending or, to the knowledge of the Company, threatened against the Company or
any of its Subsidiaries before any court, arbitrator or administrative or
governmental body that (a) seeks to enjoin or otherwise prevent the consummation
of the sale or issuance of the Securities or (b) materially and adversely
affects, or as to which there is a reasonable possibility of an adverse decision
that would materially and adversely affect, either individually or collectively,
the assets, business, properties, prospects, operations or condition, financial
or otherwise, of the Company and its Subsidiaries, taken as a whole. Neither the
Company nor any of its Subsidiaries is in violation of any judgment, order,
writ, injunction, decree, rule or regulation of any court or governmental
department, commission, board, bureau, agency or instrumentality, the violation
of which reasonably could be expected to, either individually or collectively,
materially and adversely affect the business, property, assets, prospects,
operations or condition (financial or otherwise) of the Company and its
Subsidiaries, taken as a whole.

     5.10 OFFERING OF SECURITIES. Assuming the accuracy of the representations
of Purchaser in this Agreement, the offer, sale and issuance of the Securities
are exempt from the registration requirements of the Securities Act. Neither the
Company nor any agent on its behalf has solicited or will solicit any offers to
sell or has offered to sell or will offer to sell all or any part of the
Securities to any Person so as to bring the offering and sale of such Securities
by the Company within the registration provisions of the Securities Act. The
Company has filed all notices and satisfied all registration or qualification
requirements of any state securities or Blue Sky law of any applicable
jurisdiction with respect to the offer, issuance and sale of the Securities or
required by the Ancillary Agreements.

     5.11 BROKER'S OR FINDER'S COMMISSIONS. Other than the fee payable to the
Placement Agent, no broker's or finder's or placement fee or commission will be
payable with respect to the sale or the issuance of the Securities contemplated
hereby or by the Ancillary Agreements as a result of any act or omission by the
Company, and the Company will hold Purchaser harmless from any claim, demand or
liability for broker's or finder's or placement fees or commissions alleged to
have been incurred in connection with the sale or the issuance of the Securities
due to any actions or omissions by the Company or its Subsidiaries or any of
their respective directors, officers or agents.

     5.12 APPLICATION OF PROCEEDS. The net proceeds of the sale of the Common
Stock will be used by the Company for working capital and for general corporate
purposes.

     5.13 INTELLECTUAL PROPERTY.

     (a)  The Company and its Subsidiaries exclusively own or possess the
requisite licenses or rights (on reasonable commercial terms) to use all
patents, trade secrets, trademarks,

                                       12
<Page>

service marks, service names, trade names, copyrights and other intellectual
property rights necessary to enable each of them to conduct their respective
businesses as now operated (collectively, the "COMPANY IP"). SCHEDULE 5.13(a)
sets forth a full and complete list of all intellectual property rights of the
Company and its Subsidiaries. There is no claim or action by any Person
pertaining to, or proceeding pending, or to the Company's knowledge threatened,
that challenges the rights of the Company or its Subsidiaries with respect to
any Company IP. To the Company's knowledge, neither the Company's nor any of its
Subsidiaries' current and intended products and services infringe on any
patents, licenses, trademarks, service marks, service names, trade names,
copyrights or other intellectual property rights held by any Person and neither
the Company nor any of its Subsidiaries is aware of any facts or circumstances
that might give rise to any of the foregoing.

     (b)  Except as set forth in SCHEDULE 5.13(b), no proceedings or claims in
which the Company alleges that any Person is infringing upon, or otherwise
violating, any Company IP are pending, and none has been served by, instituted
or asserted by the Company or any of its Subsidiaries, nor are any proceedings
threatened alleging any such violation or infringement.

     (c)  The Company has taken and will take all commercially reasonable
actions that are necessary or advisable in order to fully protect the Company
IP, in a manner consistent with prudent commercial practice.

     5.14 TAXES. The Company and each of its Subsidiaries has timely filed (or
caused to be filed) all Tax Returns that are required to be filed by (or with
respect to) it on or before the date hereof and has paid all Taxes due on or
before the date hereof whether or not reflected on such Tax Returns, including
pursuant to any assessment received by it. All such Tax Returns were true,
correct and complete in all material respects. None of such Tax Returns has been
audited by the relevant taxing authority, and no taxing authority has notified
(or threatened) the Company or any of its Subsidiaries, orally or in writing,
that such taxing authority will or may audit any such return. The Company and
its Subsidiaries have complied with all requirements of the Code, the Treasury
Regulations and any state, local or foreign law relating to the payment and
withholding of Taxes relating to them, and the Company and each of its
Subsidiaries have, within the time and in the manner prescribed by applicable
law, paid over to the proper taxing authorities all amounts required to be so
withheld and paid over relating to them. The charges, accruals and reserves on
the books of the Company and its Subsidiaries in respect of Taxes or other
governmental charges are adequate to cover any liability of the Company and its
Subsidiaries for Taxes through the date hereof. There are no liens for Taxes
with respect to any asset of the Company or any of its Subsidiaries, except for
liens with respect to Taxes that are not yet due and payable. No taxing
authority in a jurisdiction where the Company or any of its Subsidiaries, as the
case may be, does not file tax returns has made a claim, assertion or threat
that the Company or any of its Subsidiaries is or may be subject to taxation in
such jurisdiction.

     5.15 INSURANCE. The Company maintains or is covered by valid policies of
workers' compensation insurance, product liability insurance, and insurance with
respect to its properties and business. The Company currently maintains in full
force insurance covering the respective risks of the Company and its
Subsidiaries of such types and in such amounts, with such deductibles and with
such insurance companies as are customary for other companies engaged in similar
lines of business. The Company currently maintains key man life insurance for
John Mitola in the amount of $5,000,000, which is and will remain in full force
and effect through December 31, 2005.

     5.16 COMMISSION DOCUMENTS. Except as set forth in SCHEDULE 5.16, the
Company has filed all registration statements, proxy statements, information
statements, reports and other documents required to be filed by it under the
Securities Act or the Exchange Act, and all amendments thereto (collectively,
the "COMMISSION DOCUMENTS"). Each Commission Document when filed with the
Commission was true and accurate in all material respects and in compliance in
all material respects with the requirements of its respective report form and
the rules and regulations of the Commission. No Commission Document contained
any untrue statement of a material fact or omitted to state a material fact
required to be stated therein or necessary in order to make the statements
contained therein, in light of the circumstances under which made, not
misleading.

     5.17 DISCLOSURE. Neither this Agreement nor any other document, certificate
or statement prepared by or on behalf of the Company by its authorized
representatives or agents and furnished to or made available to the Purchaser in
writing by or on behalf of the Company by its authorized representatives or
agents in connection herewith, contains any untrue statement of a material fact
or omits to state a material fact required to be stated therein or necessary in
order to make the statements contained herein and therein, in the light of the
circumstances under which made, not misleading.

                                   ARTICLE VI
                        REPRESENTATIONS OF THE PURCHASER

     Purchaser represents and warrants as to itself only as follows:

     6.1  INVESTMENT PURPOSE. Purchaser is purchasing the Securities for
Purchaser's own account for investment only and not with a view toward or in
connection with the public sale or distribution thereof. Purchaser will not
resell the Securities except pursuant to sales that are exempt from the
registration requirements of the Securities Act and all applicable state
securities laws, and/or sales registered under the Securities Act and all
applicable state securities laws. Purchaser understands that Purchaser may bear
the economic risk of this investment indefinitely, unless the Securities are
registered pursuant to the Securities Act and any applicable state securities
laws or an exemption from such registration is available.

     6.2  ACCREDITED INVESTOR STATUS. Purchaser is an "accredited investor" as
that term is defined in Rule 501(a) of Regulation D promulgated under the
Securities Act. By reason of his business and financial experience,
sophistication and knowledge, Purchaser is capable of evaluating the risks and
merits of the investment made pursuant to this Agreement.

     6.3  AUTHORIZATION; ENFORCEMENT. This Agreement has been duly and validly
authorized, executed and delivered by Purchaser and is the legally valid and
binding agreement of Purchaser enforceable in accordance with its terms, except
as enforceability may be limited by applicable bankruptcy, insolvency, or
similar laws affecting the enforcement of creditors' rights generally or by
equitable principles relating to enforceability. As of the Closing Date, each
Ancillary Agreement to which Purchaser is a party will be the legally valid and
binding agreement of Purchaser enforceable in accordance with its terms, except
as enforceability may be limited by applicable bankruptcy, insolvency, or
similar laws affecting the enforcement of creditors' rights generally or by
equitable principles relating to enforceability.

                                       14
<Page>

     6.4  BROKER'S OR FINDER'S COMMISSIONS. Other than the fee payable to the
Placement Agent (which will be paid by the Company) no broker's or finder's or
placement fee or commission will be payable with respect to the sale or the
issuance of the Securities as a result of any act or omission by the Purchaser,
and the Purchaser will hold the Company harmless from any claim, demand or
liability for broker's or finder's or placement fees or commissions alleged to
have been incurred in connection with the sale or the issuance of the Securities
due to any actions of the Purchaser.

                                   ARTICLE VII
                                 INDEMNIFICATION

     7.1  INDEMNIFICATION BY COMPANY. In addition to all other sums due
hereunder or provided for in this Agreement, the Company agrees to indemnify and
hold harmless Purchaser to the fullest extent permitted by law from and against
any and all losses, claims, damages, expenses (including reasonable fees,
disbursements and other charges of counsel), damages or other liabilities
("LOSSES") resulting from:

          (i)  any breach of any representation or warranty, covenant or
     agreement of the Company in this Agreement, or

          (ii) any legal, administrative or other actions (including actions
     brought by any equityholders of the Company or derivative actions brought
     by any Person claiming through the Company or in the Company's name),
     proceedings or investigations (whether formal or informal), or written
     threats thereof, based upon, relating to or arising out of any of the
     Transaction Documents or the Securities, the transactions contemplated
     hereby or thereby, or any indemnified person's role therein;

PROVIDED, HOWEVER, that the Company shall not be liable under this SECTION 7.1:
(a) for any amount paid in settlement of claims without the Company's consent
(which consent shall not be unreasonably withheld or delayed) or (b) to the
extent that it is finally judicially determined that such Losses resulted
primarily from the willful misconduct, bad faith or gross negligence of
Purchaser or a breach of such Purchaser's representations in ARTICLE VI;
PROVIDED, FURTHER, that if and to the extent that such indemnification is
unenforceable for any reason, the Company shall make the maximum contribution to
the payment and satisfaction of such indemnified liability that shall be
permissible under applicable laws. In connection with the obligation of the
Company to indemnify for expenses as set forth above, the Company further agrees
to reimburse the Purchaser for all such expenses (including reasonable fees,
disbursements and other charges of counsel) as they are incurred by the
Purchaser; PROVIDED, HOWEVER, that in no event shall the Company be required to
pay fees and expenses under this ARTICLE VII for more than one firm of attorneys
in addition to the firm of attorneys representing the Company in any
jurisdiction in any one legal action or group of related legal actions;
PROVIDED, FURTHER, that if the Purchaser is reimbursed hereunder for any
expenses, such reimbursement of expenses shall be refunded to the extent it is
finally judicially determined that the Losses in question resulted primarily
from the willful misconduct, bad faith or gross negligence of the Purchaser.

     7.2  INDEMNIFICATION FOR REGISTRATION. (a) In the event of a registration
of the Common Shares and the Common Stock evidenced by the Common Stock Warrants
under the Securities Act pursuant to SECTION 4.4 herein, the Company shall
indemnify and hold harmless, to the

                                       15
<Page>

fullest extent permitted by law, the Purchaser, each underwriter of such
Eligible Securities and each other 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 Purchaser, or any such underwriter or
controlling person, may become subject under the Securities Act or otherwise or
in any action in respect thereof, and will reimburse each such Person for any
legal or other expenses reasonably incurred by him or it in connection with
investigating or defending any such loss, claim, damage, liability or action as
such expenses are incurred, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
any registration statement under which such Eligible Securities were registered
under the Securities Act pursuant to SECTION 4.4, any preliminary prospectus or
final prospectus contained therein, or any amendment or supplement thereof, 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; PROVIDED, HOWEVER, that the Company shall not
be liable to Purchaser or any such underwriter or controlling person, in any
such case if and to the extent that any such loss, claim, damage or liability
arises out of or is based upon an untrue statement or alleged untrue statement
or omission or alleged omission made in conformity with information furnished by
Purchaser or any such underwriter or controlling person, in writing specifically
for use in such registration statement or prospectus.

          (b)  Purchaser will indemnify and hold harmless the Company, each
underwriter and each person, if any, who controls the Company or any underwriter
within the meaning of the Securities Act, each officer of the Company who signs
the registration statement, each director of the Company, each other seller of
securities registered by the registration statement covering such Eligible
Securities and each person, if any, who controls such seller, against all
losses, claims, damages or liabilities, joint or several, to which the Company
or any such officer, director, underwriter, other seller or controlling person
may become subject under the Securities Act or otherwise, and shall reimburse
the Company and each such officer, director, underwriter, other seller and
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, insofar as such losses, claims, damages or liabilities (or
action in respect thereof) arise out of or are based upon an untrue statement or
alleged untrue statement of material fact, or omission or alleged omission of a
material fact required to be stated therein, made in reliance upon and in
conformity with information pertaining to Purchaser furnished in writing to the
Company by Purchaser specifically for use in the registration statement or
prospectus relating to such Eligible Securities. Notwithstanding the immediately
preceding sentence, the aggregate liability of Purchaser hereunder shall not in
any event exceed the net proceeds received by Purchaser from the sale of
Eligible Securities covered by such registration statement.

          (c)  The reimbursements required by this SECTION 7.2 shall be made by
periodic payment during the course of the investigation or defense, as and when
bills are received and expenses incurred.

          (d)  The indemnification provided for under this SECTION 7.2 shall
remain in full force and effect regardless of any investigation made by or on
behalf of the indemnified party or any officer, director, employee, agent, or
controlling person of such indemnified party and shall survive the transfer of
securities.

                                       16

     7.3  NOTIFICATION. Each indemnified party under this ARTICLE VII shall,
promptly (and in any event within 20 days) after the receipt of notice of the
commencement of any action or other proceeding against such indemnified party in
respect of which indemnity may be sought from the Company under this ARTICLE
VII, notify the Company in writing of the commencement thereof. The failure of
any indemnified party so to notify the Company of any such action shall not
relieve the Company from any liability that it may have to such indemnified
party pursuant to this ARTICLE VII, except to the extent that such failure
causes material prejudice to the Company. In case any such action or other
proceeding shall be brought against any indemnified party and it shall notify
the Company of the commencement thereof, the Company shall be entitled to
participate therein and, to the extent that it may wish, to assume the defense
thereof, with counsel reasonably satisfactory to such indemnified party;
PROVIDED, HOWEVER, that any indemnified party may, at its own expense, retain
separate counsel to participate in such defense. Notwithstanding the foregoing,
in any action or proceeding in which both the Company and an indemnified party
is, or is reasonably likely to become, a party, such indemnified party shall
have the right to employ separate counsel at the Company's expense and to
control its own defense of such action or proceeding if, in the reasonable
written opinion of counsel to such indemnified party (obtained at the expense of
the Company), (a) there are or may be legal defenses available to such
indemnified party or to other indemnified parties that are different from or
additional to those available to the Company or (b) any conflict or potential
conflict exists between the Company and such indemnified party that would make
such separate representation advisable; PROVIDED, HOWEVER, that in no event
shall the Company be required to pay fees and expenses under this ARTICLE VII
for more than one firm of attorneys in addition to the firm of attorneys
representing the Company in any jurisdiction in any one legal action or group of
related legal actions. The Company shall not, without the consent of the
indemnified party (which consent shall not be unreasonably withheld), consent to
the entry of any judgment or enter into any settlement that 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 or that requires action other than the payment of money by the
Company. The rights accorded to indemnified parties hereunder shall be in
addition to any rights that any indemnified party may have at common law, by
separate agreement or otherwise.

     7.4  PAYMENT. No indemnifying party shall be liable for any amounts paid in
a settlement effected without the consent of such indemnifying party, which
consent shall not be unreasonably withheld or delayed. No indemnifying party
shall, without the indemnified party's prior written consent, consent to entry
of any judgment or enter into any settlement that does not include as an
unconditional term thereof the giving by the plaintiff to the indemnified party
of a release from all liability in respect of such claim or litigation.

     7.5  SURVIVAL OF PROVISIONS OF ARTICLE VII. The obligations of the Company
under this ARTICLE VII shall survive indefinitely.

                                  ARTICLE VIII
                                  MISCELLANEOUS

     8.1  EXPENSES. The Company agrees to pay, and save Purchaser harmless

          (a)  During the term of this Agreement and at any time the Closing

     than $2.00 per share, Kiphart may sell any of his Subject Common Stock into
     the public market, subject to the following conditions:

          the conversion or exchange of all securities convertible or

          Agreement (as adjusted for stock splits, stock combinations and the
          like); and

               (iii) Block Sales must be executed at a minimum price per share
          of ninety percent (90%) of the ask price as reported on the American

          national securities exchange or automated quotation services on which
          the Common Stock is then listed for trading).

          (b)  During the term of this Agreement and at any time the Closing
     Price on the then prior trading day is less than $1.00 per share, Kiphart
     may sell any of his Subject Common Stock into the public market, subject to

     Agreement, Kiphart agrees that he will not engage, either directly or
     indirectly, in short sales of the Subject Common Stock and represents and
     warrants that he has not engaged, either directly or indirectly, in short
     sales of the Subject Common Stock at any time prior to the Closing Date.

the contrary, Kiphart may freely sell or otherwise transfer any Subject Common
Stock (or securities exercisable or exchangeable for or convertible into shares
of Subject Common Stock) which he owns to his Affiliates without such sale or
transfer being in violation of the terms of this Agreement; PROVIDED, HOWEVER,
that concurrently with any such transfer any such Affiliate shall become a party
to this Agreement and its ownership and sales of shares of Subject Common Stock
(or other securities exercisable or exchangeable for or convertible into shares
of Subject Common Stock) shall be aggregated with Kiphart's for purposes of
SECTION 2.2.

     2.4  TERM OF TRADING AGREEMENT. The term of this Agreement shall commence
on the Closing Date and terminate on the earlier of September 7, 2004 or the

                                   ARTICLE III
                               GENERAL PROVISIONS

     3.1       LEGEND ON SHARE CERTIFICATES.

          (a)  All shares of Subject Common Stock that are subject to the terms
and provisions of ARTICLE II, in addition to such other legends as may be
required by law and any other legend required by any agreement or document
executed in connection with the closing under the Kiphart Securities Purchase
Agreement, shall bear the following legend:

          THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
          REQUIREMENTS AS TO TRADING CONTAINED IN THE STOCK TRADING AGREEMENT,
          DATED AS OF APRIL 23, 2003, BETWEEN THE COMPANY AND THE HOLDER, A COPY
          OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY.

          (b)  Upon the termination of this Agreement or for sales in
conformance with the provisions of this Trading Agreement, Kiphart (or the
applicable purchaser) shall be entitled to receive, in exchange for any security
bearing the legend regarding this Agreement specifically set forth in SECTION
3.1(a), a security without such legend.

                                   ARTICLE IV
                                  MISCELLANEOUS

     4.1  INJUNCTIVE RELIEF. It is acknowledged that it is impossible to measure
in money the damages that would be suffered if Kiphart fails to comply with the
obligations imposed on him by this Agreement and that, in the event of any such
failure, the Company would be irreparably damaged and would not have an adequate
remedy at law. The Company shall, therefore, be entitled to injunctive relief
and/or specific performance to enforce such obligations of Kiphart, and if any
action should be brought in equity to enforce any of such provisions of this
Agreement, Kiphart shall not raise the defense that there is an adequate remedy
at law.

     4.2  GOVERNING LAW. Except as to matters governed by the General
Corporation Law

                                      - 4 -
<Page>

of the State of Delaware and decisions thereunder of the Delaware courts
applicable to Delaware corporations, which shall be governed by such laws and
decisions, this Agreement shall be construed and enforced in accordance with,
and the rights of the Parties shall be governed by, the laws of the State of
Illinois.

     4.3  ENTIRE AGREEMENT; WAIVER. This Agreement contains the entire agreement
among the Parties hereto with respect to the subject matter hereof. No waiver of
any term or provision shall be effective unless in writing signed by the Party
to be charged in accordance herewith.

     4.4  BINDING EFFECT. This Agreement shall be binding on and inure to the
benefit of the Parties and, subject to the terms and provisions hereof, their
respective legal representatives, successors and assigns.

     4.5  INVALIDITY OF PROVISION. The invalidity or unenforceability of any
provision of this Agreement in any jurisdiction shall not affect the validity or
enforceability of the remainder of this Agreement in that jurisdiction or the
validity or enforceability of this Agreement, including that provision, in any
other jurisdiction.

     4.6  COUNTERPARTS. This Agreement may be executed in two or more
counterparts, all of which shall be deemed but one and the same instrument and
each of which shall be deemed an original, and it shall not be necessary in
making proof of this Agreement to produce or account for more than one such
counterpart for each of the parties hereto. Delivery by facsimile by any of the
Parties hereto of an executed counterpart of this Agreement shall be effective
as an original executed counterpart hereof and shall be deemed a representation
that an original executed counterpart hereof will be delivered.

     4.7  NOTICES. All notices, consents and other communications under this
Agreement shall be in writing and shall be deemed to have been duly given when
(a) delivered by hand, (b) sent by facsimile (with receipt confirmed), provided
that a copy is mailed by certified mail, return receipt requested, or (c) when
received by the addressee, if sent by Express Mail, Federal Express or other
reputable express delivery service (receipt requested), in each case to the
