     By Lease dated January 14, 2002 (the "Lease") Landlord did lease to Tenant

Massachusetts (referred to in the Lease as the "Premises" or "Tenant's Space"
and hereinafter sometimes referred to as the "Initial Premises").

     Landlord and Tenant have agreed to terminate the Lease with regard to the
entire Initial Premises (hereinafter sometimes referred to as the "Relinquished
Premises") and Tenant has determined to lease from Landlord the 28,966 square
feet of rentable floor area (the "Rentable Floor Area of the New Premises")
located on the fourth (4th) floor of the Building and shown on Exhibit A
attached hereto (such space being hereinafter referred to as the "New Premises")
upon the terms and conditions contained in this First Amendment to Lease (the
"First Amendment") .

     Landlord and Tenant are entering into this instrument to set forth said
leasing of the New Premises and to amend the Lease.

     NOW, THEREFORE, in consideration of One Dollar ($1.00) and other good and
valuable consideration in hand this date paid by each of the parties to the

     10 below), the New Premises shall constitute a part of the "Premises" (and

     Premises shall no longer be deemed to be a part of and shall be deleted and
     removed from the "Premises" (and "Tenant's Space") demised to Tenant under
     the Lease. In addition, solely for the purposes of Section 4 below, it is
     understood and agreed that the New Premises shall be comprised of two
     separate spaces: (a) "New Premises A," consisting of 7,353 square feet of
     rentable floor area (the "Rentable Floor Area of New Premises A"); and (b)
     "New Premises B," consisting of 21,613 square feet of rentable floor area
     (the "Rentable Floor Area of New Premises B").

2.   Subject to the provisions of Section 13(F) below, Tenant shall quit and
     vacate the Relinquished Premises within five (5) business days after the
     occurrence of the New Premises Commencement Date and surrender the same to

          for calendar year 2003 (that is the period beginning January 1, 2003
          and ending December 31, 2003)."

     In addition, for the purpose of calculating Landlord's Operating Expenses
     under Section 2.6 for that portion of the Lease Term on and after the New
     Premises Commencement Date, the following new paragraph shall be added
     after the end of the first paragraph of said Section 2.6:

          "Notwithstanding the foregoing, the following shall be excluded from

                    personnel or officers of Landlord;

          (ii)      All capital expenditures and depreciation, except as
                    otherwise explicitly provided in this Section 2.6;

          (iii)     Costs of repairs or replacements incurred by reason of fire
                    or other casualty or condemnation other than costs not in

                    Landlord which provides a recovery for such repair or
                    replacement;

          (iv)      Costs of any services or materials provided by any party
                    related to Landlord, to the extent such costs exceed the
                    reasonable costs for such services or materials absent such
                    relationship in buildings similar to the Building in the
                    vicinity of the Building;

          (v)       Initial costs of tools and equipment used in the repair and

                    Building or on the Site required by "Hazardous Materials
                    Laws" (as defined in said Section 5.3), except to the extent
                    necessitated by the acts or omissions of Tenant or its
                    agents or employees;

          (viii)    Leasing fees or commissions, advertising and promotional or
                    marketing expenses incurred in connection with leasing space

          (ix)      Costs of correcting defects in the original design or
                    construction of the Building."

     (C)  For the purposes of calculating Tenant's payments for Landlord's Tax
     Expenses pursuant to Section 2.7 of the Lease for that part of the Lease
     Term prior to the New Premises Commencement Date, the provisions of said
     Section 2.7 of the Lease shall be

                                      - 4 -
<Page>

     unchanged. For that portion of the Lease Term on and after the New Premises
     Commencement Date, the first two sentences of the first paragraph of
     Section 2.7 shall be deleted in their entirety and substituted with the
     following:

          "If with respect to any full Tax Year or fraction of a Tax Year
          falling within the Term, Landlord's Tax Expenses Allocable to the
          Premises (as hereinafter defined) for a full Tax Year exceed Base
          Taxes Allocable to the Premises (as hereinafter defined), or for any
          such fraction of a Tax Year exceed the corresponding fraction of Base
          Taxes Allocable to the Premises, then, on or before the thirtieth
          (30th) day following receipt by Tenant of the certified statement
          referred to below in this Section 2.7, Tenant shall pay to Landlord,
          as Additional Rent, the amount of such excess."

     In addition, for the purpose of calculating Landlord's Tax Expenses under
     Section 2.7 for that portion of the Lease Term on and after the New
     Premises Commencement Date, the following language shall be added to the
     definitions appearing in the last paragraph of said Section 2.7:

          "(v)      'Base Taxes' shall mean Landlord's Tax Expenses for fiscal
                    tax year 2004 (being July 1, 2003 through June 30, 2004).

          (vi)      'Base Taxes Allocable to the Premises' means the same
                    proportion of Base Taxes for and pertaining to the Building
                    and the Site as the Rentable Floor Area of Tenant's Space
                    bears to the Total Rentable Floor Area of the Building.

          (vii)     If during the Lease Term the Tax Year is changed by
                    applicable law to less than a full 12-month period, the Base
                    Taxes and Base Taxes Allocable to the Premises shall each be
                    proportionately reduced.

          (viii)    In the event that the Building and the Site are not fully
                    assessed during any fiscal tax year during the Lease Term
                    (including, without limitation, fiscal tax year 2004 for the
                    purposes of calculating Base Taxes), Landlord's Tax Expenses
                    for such fiscal tax year shall be determined by Landlord to
                    be an amount equal to the Landlord's Tax Expenses which
                    would normally be expected to have been charged had the
                    Building and the Site been fully assessed during such fiscal
                    tax year."

     (D)  Notwithstanding anything contained herein or in the Lease to the
     contrary, it is understood and agreed that in the event that Landlord shall
     construct another building on the Site at any time during the Lease Term:

          (i)       the definition of "Operating Expenses Allocable to the
                    Premises" contained in Section 2.6 of the Lease shall be
                    amended to mean (a) the same proportion of Landlord's
                    Operating Expenses for and pertaining to the Building as the
                    Rentable Floor Area of the Premises bears to the Total
                    Rentable Floor Area of the Building PLUS (b) the same
                    proportion of Landlord's Operating Expenses for and
                    pertaining to the Site as the

                                      - 5 -
<Page>

                    Rentable Floor Area of the Premises bears to the total
                    rentable floor area of all buildings on the Site (including
                    the Building); and

          (ii)      the definition of "Landlord's Tax Expenses Allocable to the
                    Premises" contained in Section 2.7 of the Lease shall be
                    amended to mean (a) the same proportion of Landlord's Tax
                    Expenses for and pertaining to the Building as the Rentable
                    Floor Area of the Premises bears to the Total Rentable Floor
                    Area of the Building PLUS (b) the same proportion of
                    Landlord's Tax Expenses for and pertaining to the Site as
                    the Rentable Floor Area of the Premises bears to the total
                    rentable floor area of all buildings on the Site (including
                    the Building).

6.   Effective as of the New Premises Commencement Date, the definition of
     "Permitted Use" contained in Section 1.1 of the Lease is hereby amended by
     deleting the numerals "500" in clause (y) thereof and substituting the
     numerals "3,000" therefor.

7.   Section 2.1.1 of the Lease is hereby deleted in its entirety.

8.   Effective as of the New Premises Commencement Date, the Number of Parking
     Spaces which Tenant shall have the right to use pursuant to Sections 1.1
     and 2.2.1 of the Lease shall be increased from twenty-nine (29) to one
     hundred sixteen (116).

9.   Effective as of the New Premises Commencement Date, Section 2.6 of the
     Lease is hereby amended by deleting in its entirety the last grammatical
     paragraph thereof and substituting the following therefor:

          "Upon no less than ten (10) business days' prior written notice to
          Landlord, Tenant or its representatives at Tenant's expense may
          examine Landlord's books and records to confirm that the Landlord's
          Operating Expenses billed to Tenant are proper and conform to Section
          2.6 this Lease, such examination to take place during normal business
          hours at Landlord's office. Such right shall be exercisable by Tenant
          within six (6) months following Tenant's receipt of Landlord's annual
          statement, time being of the essence. Tenant covenants and agrees that
          no such audit shall be conducted on a contingent fee basis paid to the
          auditor but shall be contracted and paid for on a fixed-fee basis.
          Tenant shall hold such books, records and other information gathered
          from such examination in confidence and not disclose the same to any
          other party, including, without limitation, any other tenant in the
          Building (it being acknowledged and agreed that as a condition to
          making its books and records available hereunder, Landlord shall have
          the right to require Tenant and its examiners to execute and deliver
          an agreement in form and substance reasonably acceptable to Landlord
          confirming such obligation of confidentiality). If such examination
          reveals that Landlord's Operating Expenses for the applicable calendar
          year have been overstated by Landlord, then an equitable adjustment
          shall be made in the amount paid by Tenant pursuant to this Section
          2.6 for such calendar year and appropriate credit shall be made
          against (i) monthly installments of Annual Fixed Rent next thereafter
          coming due or (ii) any other sums due from Tenant to Landlord under
          this Lease (or refund such amount

                                      - 6 -
<Page>

          within thirty (30) days of final determination if the Term has ended
          and Tenant has no further obligation to Landlord). In addition, in the
          event that such audit by Tenant discloses such an overcharge in excess
          of five percent (5%) in the aggregate, then Landlord shall pay to
          Tenant within thirty (30) days after the receipt of a request therefor
          the reasonable out-of-pocket expenses of the third party auditor
          actually incurred by Tenant but not to exceed Five Thousand Dollars
          ($5,000.00). If such examination reveals that Landlord's Operating
          Expenses for the applicable calendar year have been understated by
          Landlord, then an equitable adjustment shall be made in the amount
          paid by Tenant pursuant to this Section 2.6 for such calendar year and
          an appropriate payment shall be made by Tenant to Landlord within
          thirty (30) days after Landlord bills Tenant therefor."

10.  (A)  Effective as of the New Premises Commencement Date, Section 5.6.1.1 of
     the Lease is hereby deleted in its entirety and the following substituted
     therefor:

          "Notwithstanding the provisions of Section 5.6 above, in the event
          Tenant desires (i) to assign this Lease or (ii) to sublet all or any
          portion of the Premises for all or substantially all of the
          then-remaining Lease Term, Tenant shall notify Landlord thereof in
          writing and Landlord shall have the right at its sole option, to be
          exercised within thirty (30) days after receipt of Tenant's notice, to
          terminate this Lease as of a date specified in a notice to Tenant,
          which date shall not be earlier sixty (60) days nor later than one
          hundred twenty (120) days after Landlord's notice to Tenant; provided,
          however, that upon the termination date, all obligations relating to
          the period after such termination date (but not those relating to the
          period before such termination date) shall cease and promptly upon
          being billed therefor by Landlord, Tenant shall make final payment of
          all Annual Fixed Rent and Additional Rent due from Tenant through the
          termination date. Notwithstanding the foregoing, in the event that
          Tenant shall only propose to sublease a portion of the Premises for
          all or substantially all of the then-remaining Lease Term, Landlord
          shall only have the right to so terminate this Lease with respect to
          the portion of the Premises which Tenant proposes to sublease (the
          "Terminated Portion of the Premises") and from and after the
          termination date the Rentable Floor Area of the Premises shall be
          reduced to the rentable floor area of the remainder of the Premises
          and the definition of Rentable Floor Area of the Premises shall be so
          amended and after such termination all references in this Lease to the
          "Premises" or the "Rentable Floor Area of the Premises" shall be
          deemed to be references to the remainder of the Premises and
          accordingly Tenant's payments for Annual Fixed Rent, operating costs,
          real estate taxes and electricity shall be reduced on a pro rata basis
          to reflect the size of the remainder of the Premises. In the case of a
          partial subletting where Landlord has exercised its termination right
          pursuant to this Section 5.6.1.1, Tenant shall pay to Landlord, as
          Additional Rent, within thirty (30) days after demand therefor, the
          reasonable cost to separately physically demise that portion of the
          Premises which are being terminated from the remainder of the
          Premises.

          If Landlord notifies Tenant of Landlord's election to terminate this
          Lease with respect to the applicable portion of the Premises pursuant
          to this Section 5.6.1.1,

                                      - 7 -

          Tenant shall have the right, by notice to Landlord given within ten
          (10) days after receipt by Tenant of Landlord's notice of termination,
          to withdraw Tenant's request to assign this Lease or sublet the
          Premises, as the case may be, in which event Landlord's election to
          terminate shall be rendered null and void.

          In the event that Landlord shall not exercise its termination rights
          as aforesaid, or shall fail to give any or timely notice pursuant to
          this Section, the provisions of Sections 5.6.2-5.6.5 shall be
          applicable. This Section 5.6.1.1 shall not be applicable to an
          assignment or sublease pursuant to Section 5.6.1."

     Notwithstanding the foregoing, it is understood and agreed that Landlord
     will not exercise its recapture rights under Section 5.6.1.1 (as amended
     hereby) with respect to Tenant's current proposed sublease to Open Pages,
     Inc.

     (B)  Effective as of the New Premises Commencement Date, Section 5.6.2 of

          Building or elsewhere on the Site and there is available space in the
          Building or elsewhere on the Site for lease by such tenant, (ii) in
          active negotiation (as evidenced by the receipt by Landlord of a
          request for proposal to lease from such party no more than ninety (90)
          days prior to Tenant's request for consent) with Landlord for premises
          in the Building or elsewhere on the Site or (iii) not of a character
          consistent with the operation of a first class office building (by way
          of example, Landlord shall not be deemed to be unreasonably
          withholding its consent to an assignment or subleasing to any
          governmental or quasi-governmental agency), or"

     (D)  Effective as of the New Premises Commencement Date, Section 5.6.2(b)
     of the Lease is hereby deleted in its entirety and the following
     substituted therefor:

          financial capability to perform the obligations of the Tenant under
          this Lease (in the case of an assignment) or of the subtenant under
          the sublease (in the case of a sublease) as and when due or required,
          or"

     (E)  Effective as of the New Premises Commencement Date, Section 5.6.3 of
     the Lease is hereby amended by deleting the last sentence of the first
     grammatical paragraph thereof. Section 5.6.3 of the Lease is hereby further
     amended by deleting the parenthetical "(the whole but not part of the

     grammatical paragraph thereof.

     (F)  Effective as of the New Premises Commencement Date, Section 5.6.5 of
     the Lease is hereby amended by deleting the words "pursuant to Section
     5.6.1" appearing in

                                      - 8 -
<Page>

     the ninth (9th) line of subsection (A) thereof. Section 5.6.5 of the Lease
     is hereby further amended by adding the following subsection (F) at the end
     thereof:

          "(F) In addition to the other requirements set forth in this Lease and
          notwithstanding any other provision of this Lease, partial sublettings
          of the Premises shall only be permitted under the following terms and
          conditions: (i) the layout of both the subleased premises and the
          remainder of the Premises must comply with applicable laws,
          ordinances, rules and/or regulations (including, without limitation,
          all requirements concerning access and egress) and must be approved by
          Landlord; (ii) in the event the subleased premises are separately
          physically demised from the remainder of the Premises, Tenant shall
          pay all costs of separately physically demising the subleased
          premises; and (iii) there shall be no more than two (2) subleases in
          effect for the Premises at any given time."

11.  Effective as of the New Premises Commencement Date, Section 8.20(B) of the
     Lease is hereby amended by adding the words "ninety-five percent (95%) of
     before the words "the Prevailing Market Rent as determined by the Broker
     Determination" in the seventh (7th) line from the bottom of such Section
     8.20(B).

12.  (A)  On or before the New Premises Commencement Date, Tenant shall deliver
     to Landlord an amendment to the existing Letter of Credit being held by
     Landlord pursuant to Section 8.21 of the Lease that increases the amount
     secured by such Letter of Credit by an additional Two Hundred Twenty-Three
     Thousand Two Hundred Ninety-Seven and 00/100 Dollars ($223,297.00), so that
     the total amount secured by the Letter of Credit shall be Three Hundred One
     Thousand Seven Hundred Twenty-Nine and 00/100 Dollars ($301,729.00) (or
     Landlord shall exchange the Letter of Credit for a new Letter of Credit in
     the amount of $301,729.00 issued by a bank reasonably approved by Landlord
     and meeting the criteria set forth in Section 8.21(A) of the Lease)

     (B)  Effective as of the New Premises Commencement Date, Section 8.21(B) of
     the Lease is hereby deleted in its entirety and the following substituted
     therefor:

          "(a) Landlord shall return a One Hundred Twenty Thousand Six Hundred
          Ninety-One and 00/100 Dollar ($120,691.00) portion of such deposit to
          Tenant so that the remainder of such deposit shall be One Hundred
          Eighty-One Thousand Thirty-Eight and 00/100 Dollars ($181.038.00) (or
          if such deposit is in the form of a Letter of Credit, Landlord shall
          exchange the Letter of Credit for a Letter of Credit delivered by
          Tenant which reduces the amount secured by the Letter of Credit by the
          amount stated hereinabove) on the first day of the thirty-seventh
          (37th) full calendar month immediately following the New Premises
          Commencement Date (such date being hereinafter referred to as the
          "Scheduled Reduction Date") if (i) Tenant is not then in default under
          the terms of this Lease without the benefit of notice or grace, (ii)
          Landlord has not applied such deposit or any portion thereof to
          Landlord's damages arising from any default on the part of Tenant,
          whether or not Tenant has restored the amount so applied by Landlord
          and (iii) Tenant has satisfied the "Deposit Return Criteria" (as
          hereinafter defined). For the purposes hereof, the term "Deposit
          Return Criteria" shall mean

                                      - 9 -
<Page>

          that for Tenant's fiscal year immediately prior to the Scheduled
          Reduction Date (i) Tenant shall have generated total revenues of
          $25,000,000.00, (ii) Tenant shall have a net operating income of
          $3,500,000.00 and (iii) Tenant shall have a leverage ratio (i.e. a
          ratio of total liabilities to total equity) of no more than 1.5, each
          of the foregoing being as determined in accordance with generally
          accepted accounting principles consistently applied. In order to
          demonstrate that Tenant has satisfied the Deposit Return Criteria,
          Tenant shall deliver to Landlord audited financial statements for the
          fiscal year immediately prior to the Scheduled Reduction Date as and
          when made publicly available, if Tenant's stock is then publicly
          traded. If Tenant's stock is not then publicly traded, Tenant shall
          deliver to Landlord copies of Tenant's annual financial statements,
          prepared by an independent certified public accounting firm reasonably
          acceptable to Landlord and in form reasonably acceptable to Landlord.
          All such financial statements shall be prepared in accordance with
          generally accepted accounting principles, consistently applied.

          (b)  Tenant not then being in default and having performed all of its
          obligations under this Lease, including the payment of all Annual
          Fixed Rent and Additional Rent, Landlord shall return the deposit,
          including all interest earned thereon, or so much thereof as shall not
          have theretofore been applied in accordance with the terms of this
          Section 8.21, to Tenant on the expiration or earlier termination of
          the term of this Lease (as the same may have been extended) and
          surrender possession of the Premises by Tenant to Landlord in the
          condition required in the Lease at such time."

13.  (A)  Attached as Exhibit B hereto are (i) a space plan showing the work to
     be performed by Landlord, at Landlord's cost and expense, in order to
     prepare the New Premises for Tenant's use and occupancy (such work being
     hereinafter referred to as "Landlord's Work") and (ii) a description of
     Landlord's building-standard finishes. For the purposes of this First
     Amendment, the term "Landlord's Work" shall mean all labor, materials and
     other work necessary for the construction of the improvements described in
     Exhibit B; provided, however, that Landlord shall have no responsibility
     for the installation or connection of Tenant's computer, telephone, other
     communication equipment, security, furniture, systems or wiring. Any items
     of work requested by Tenant and not shown on the Exhibit B (including,
     without limitation, the selection of non-building standard items) shall be
     deemed to be Change Proposal(s) (as defined below) and shall be subject to
     the terms and provisions of subsection (B) below.

     (B)  Tenant shall have the right, in accordance herewith, to submit for
     Landlord's approval change proposals with respect to items of work not
     shown on Exhibit B (each, a "Change Proposal"). Landlord agrees to respond
     to any such Change Proposal within such time as is reasonably necessary
     (taking into consideration the information contained in such Change
     Proposal) after the submission thereof by Tenant, advising Tenant of any
     anticipated costs ("Change Order Costs") associated with such Change
     Proposal, as well as an estimate of any delay which would likely result in
     the completion of the Landlord's Work if a Change Proposal is made pursuant
     thereto ("Landlord's Change Order Response"). Tenant shall have the right
     to then approve or withdraw such Change

                                     - 10 -
<Page>

     Proposal within five (5) days after receipt of Landlord's Change Order
     Response. If Tenant fails to respond to Landlord's Change Order Response
     within such five (5) day period, such Change Proposal shall be deemed
     withdrawn. If Tenant approves such Change Proposal, then such Change
     Proposal shall be deemed a "Change Order" hereunder and if the Change Order
     is made, then the Change Order Costs associated with the Change Order shall
     be deemed additions to the Tenant Plan Excess Costs and shall be paid in
     the same manner as Tenant Plan Excess Costs are paid as set forth in
     subsection (I) below.

     (C)  The New Premises shall be treated as having been substantially
     completed and the New Premises Commencement Date shall be deemed to occur
     on the later of:

          (i)       The date on which Landlord's Work, together with common
                    facilities for access and services to the New Premises, has
                    been completed (or would have been completed except for
                    Tenant Delay) except for items of work and adjustment of
                    equipment and fixtures which can be completed after
                    occupancy has been taken without causing substantial
                    interference with Tenant's use of the Premises (i.e.
                    so-called "punch list" items), or

          (ii)      The date when permission has been obtained from the
                    applicable governmental authority, to the extent required by
                    law, for occupancy by Tenant of the New Premises for the
                    Permitted Use, unless the failure to obtain such permission
                    is due to a Tenant Delay.

     In the event of any dispute as to the date on which Landlord's Work has
     been completed, the reasonable determination of Landlord's architect as to
     such date shall be deemed conclusive and binding on both Landlord and
     Tenant.

     As soon as may be convenient after the New Premises Commencement Date has
     been determined, Landlord and Tenant agree to join with each other in the
     execution of a written Declaration, in the form of Exhibit E attached to
     the Lease, in which the New Premises Commencement Date and the Original
     Term of this Lease shall be stated. If Tenant fails to execute such
     Declaration, the Commencement Date and Original Term shall be as reasonably
     determined by Landlord in accordance with the terms of this First
     Amendment.

     (D)  Landlord shall complete as soon as conditions practically permit any
     incomplete items of Landlord's Work, and Tenant shall cooperate with
     Landlord in providing access as may be required to complete such work in a
     normal manner.

     (E)  Landlord shall permit Tenant access for installing Tenant's trade
     fixtures in portions of the New Premises prior to substantial completion
     when it can be done without material interference with remaining work or
     with the maintenance of harmonious labor relations. Any such access by
     Tenant shall be upon all of the terms and conditions of the Lease (other
     than the payment of Annual Fixed Rent) and shall be at Tenant's sole risk,
     and Landlord shall not be responsible for any injury to persons or damage
     to property resulting from such early access by Tenant.

                                     - 11 -
<Page>

     (F)  If, prior to the date that the New Premises are in fact actually
     substantially complete, the New Premises are deemed to be substantially
     complete pursuant to the provisions of this Section 13 as the result of a
     Tenant Delay (i.e. and the New Premises Commencement Date has therefore
     occurred), Tenant shall not (except with Landlord's consent) be entitled to
     take possession of the New Premises for the Permitted Use until the New
     Premises are in fact actually substantially complete. Notwithstanding
     anything contained in this First Amendment to the contrary, if the New
     Premises are deemed substantially complete hereunder as the result of a
     Tenant Delay but are not in fact substantially complete such that Tenant
     can take possession of the New Premises for the Permitted Use, Tenant shall
     be entitled to remain in possession of the Relinquished Premises until the
     first to occur of (x) the date which is five (5) business days following
     the date on which the New Premises are in fact substantially complete such
     that Tenant can take possession thereof for the Permitted Use and (y) the
     date which is forty-five (45) days following the date on which the New
     Premises were deemed substantially complete hereunder. Any such continued
     occupancy of the Relinquished Premises shall be upon the terms and
     conditions of this First Amendment.

     (G)  A "Tenant Delay" shall be defined as the following:

          (i)       Tenant's failure to pay the Tenant Plan Excess Costs in
                    accordance with subsection (I) below;

          (ii)      Any delay due to items of work for which there is long lead
                    time in obtaining the materials therefor or which are
                    specially or specifically manufactured, produced or milled
                    for the work in or to the New Premises and require
                    additional time for receipt or installation;

          (iii)     Any delay due to changes, alterations or additions required
                    or made by Tenant with respect to items not shown on Exhibit
                    B including, without limitation, Change Orders; or

          (iv)      Any other delays caused by Tenant, Tenant's contractors,
                    architects, engineers, or anyone else engaged by Tenant in
                    connection with the preparation of the Premises for Tenant's
                    occupancy, including, without limitation, utility companies
                    and other entities furnishing communications, data
                    processing or other service, equipment, or furniture.

     (H)  Tenant covenants that no Tenant Delay shall delay the New Premises
     Commencement Date or the obligation to pay Annual Fixed Rent or Additional
     Rent, with respect to the New Premises regardless of the reason for such
     Tenant Delay or whether or not it is within the control of Tenant or any
     such employee. Landlord's Work shall be deemed substantially completed as
     of the date when Landlord's Work would have been substantially completed
     but for any Tenant Delays, as determined by Landlord in the exercise of its
     good faith business judgement.

     In addition, Tenant shall reimburse Landlord the amount, if any, by which
     the cost of Landlord's Work is increased as the result of any Tenant Delay.
     Any amounts due from

                                     - 12 -
<Page>

     Tenant to Landlord under this Section 13(H) shall be due and payable within
     thirty (30) days of billing therefor, and shall be considered to be
     Additional Rent. Nothing contained in this Section 13(H) shall limit or
     qualify or prejudice any other covenants, agreements

     (I)  Notwithstanding anything contained in this Section 13 to the contrary,
     it is understood and agreed that Tenant shall be fully responsible for the
     costs of any items of work not shown on Exhibit B hereto (the "Tenant Plan
     Excess Costs"). To the extent, if any, that there are Tenant Plan Excess
     Costs, Tenant shall pay Landlord, as Additional Rent, fifty percent (50%)
     of the Tenant Plan Excess Costs prior to the commencement of the Landlord's
     Work, with the balance of the Tenant Plan Excess Costs due upon substantial
     completion of the Landlord's Work; provided, however, that in the event
     that the Tenant Plan Excess Costs exceed $100,000.00 (the "Maximum
     Amount"), then Tenant shall pay to Landlord, as Additional Rent, at the
     time that Tenant approves any Change Order that causes the Tenant Plan
     Excess Costs to exceed the Maximum Amount, all Tenant Plan Excess Costs in
     excess of the Maximum Amount.

     (J)  Except to the extent to which Tenant shall have given Landlord notice
     of respects in which Landlord has not performed Landlord's construction
     obligations under this Section 13 (i) not later than the end of the sixth
     (6th) full calendar month next beginning after the New Premises
     Commencement Date with respect to the heating, ventilating and air
     conditioning systems servicing the Premises, and (ii) not later than the
     third (3rd) full calendar month next beginning after the New Premises
     Commencement Date with respect to Landlord's construction obligations under
     this Section 13 not referenced in (i) above, Tenant shall be deemed
     conclusively to have approved Landlord's construction and shall have no
     claim that Landlord has failed to perform any of Landlord's obligations
     under this Section 13. Landlord agrees to correct or repair at its expense
     items of Landlord's Work which are then incomplete or do not conform to the
     work contemplated under Exhibit B and as to which, in either case, Tenant
     shall have given notice to Landlord, as aforesaid.

     (K)  As an inducement to Tenant's entering into this First Amendment,
     Landlord shall provide to Tenant a special allowance of $108,622.50 to be
     used by Tenant towards the costs of the work to be performed by Tenant to
     install its telecommunications, data and security systems in the New
     Premises. In addition, it is understood and agreed that Tenant may utilize
     up to $43,449.00 of this special allowance towards the expenses incurred by
     Tenant in moving its business operations to the New Premises (such as the
     cost of retaining the moving company, the cost of ordering new stationary
     and business cards, etc.). Provided that the Tenant (i) has completed all
     of such work, has paid for all of such work in full and has delivered to
     Landlord lien waivers from all persons who might have a lien as a result of
     such work, in recordable form, (ii) has delivered to Landlord its
     certificate as to the cost of such work together with evidence thereof in
     the form of paid invoices, receipts and the like, (iii) has made request
     for such payment on or before the date that is sixty (60) days after the
     New Premises Commencement Date, (iv) has executed and delivered the
     Commencement Date Agreement described in subsection (C) above and (v) is
     not otherwise in default under this Lease, then within thirty (30) days
     after the satisfaction of the foregoing conditions, Landlord shall pay to
     Tenant the lesser

                                     - 13 -
<Page>

     of the amount of such costs so certified or the amount of such special
     allowance. In the event that such cost of Tenant's work is less than the
     special allowance Tenant shall not be entitled to any payment or credit nor
     shall there be any application of the same toward Annual Fixed Rent or
     Additional Rent owed by Tenant under the Lease.

14.  (A)  Landlord shall give Tenant notice every six (6) months ("Landlord's
     Availability Notice"), beginning with the first day of the sixth (6th) full
     calendar month immediately following the New Premises Commencement Date, as
     to the availability of space for lease on the fourth (4th) floor of the
     Building as shown on Exhibit A attached hereto (the "First Offer Space")
     and the business terms upon which Landlord is currently offering the space
     in the marketplace, until such time as all of the First Offer Space has
     been initially leased. Notwithstanding the foregoing, in the event that
     there is no available space (i.e. space that has not been committed to a
     third party) on the fourth (4th) floor of the Building as of the date that
     Landlord is required to deliver its first Landlord's Availability Notice
     hereunder, the "First Offer Space" shall be deemed to be the entire third
     (3rd) floor of the Building as shown on Exhibit A-1 attached hereto, and
     Tenant shall have no further rights under this Section 14 with respect to
     portions of the fourth (4th) floor of the Building outside of the Premises.
     Subject to the rights of any tenant in the Building as of the date hereof
     and to the rights of any tenants who may lease portions of the First Offer
     Space with respect to which Tenant had previously declined to exercise its
     rights under this Section 14, which rights are prior to the rights of
     Tenant under this Section 14 and notwithstanding that amendment to an
     existing lease may be executed subsequent to the date of this First
     Amendment, and provided that at the time of Landlord's Availability Notice
     (i) Tenant is not then in default in the performance of any of its
     obligations under this Lease, (ii) Tenant has not assigned this Lease or
     sublet more than thirty-three percent (33%) of the Total Rentable Floor
     Area of the Premises (except for that certain sublease between Tenant and
     Open Pages, Inc., which such sublease shall nonetheless be subject to the
     terms and provisions of the Lease), and (iii) this Lease is still in full
     force and effect, Tenant shall have an opportunity to lease the
     then-available portions of the First Offer Space set forth in Landlord's
     most recent Landlord's Availability Notice in accordance with the
     procedures set forth in subsection (B) below.

     (B)  If Tenant wishes to exercise Tenant's right of first offer, Tenant
     shall do so, if at all, by giving Landlord notice of Tenant's desire to
     lease the entire amount of such space (it being agreed that Tenant has no
     right to lease less than the entire amount of the space which is so
     available) on the terms set forth in the most recent Landlord's
     Availability Notice within ten (10) days after receipt of Landlord's
     Availability Notice, time being of the essence. If Tenant shall give such
     notice the same shall constitute an agreement to enter into an instrument
     in writing to lease such space within thirty (30) days thereafter upon all
     of the same terms and conditions in the Lease except for the provisions of
     this Section 14, the Annual Fixed Rent (which shall be the annual fair
     market rent for such space as of the date when the same becomes so
     available, based upon the use of such space as first class office space
     utilizing properties of similar character within the Boston West Suburban
     market), such other business terms as are set forth in Landlord's
     Availability Notice and those provisions which are inappropriate to the
     business agreement. If Tenant shall not so exercise such right within such

     prior to the delivery of the next Landlord's Availability Notice to enter
     into a lease of such space with another prospective tenant upon terms
     substantially no less favorable to Landlord than those set forth in the
     most recent Landlord's Availability Notice; provided, however, that if
     Landlord proposes to lease such space upon terms substantially less
     favorable to Landlord than contained in the most recent Landlord's
     Availability Notice, Landlord must first re-offer such portion of the First
     Offer Space to Tenant in accordance with the terms of this Section 14. In
     addition, it is understood and agreed that the rights provided to Tenant
     under this Section 14 shall terminate with respect to any portion of the
     First Offer Space that has been leased to a third party, and the rights
     provided hereunder shall be entirely null and void and of no further force
     and effect at such time as the First Offer Space has been fully leased.

     (C)  If Tenant shall exercise any such right of first offer and if,
     thereafter, the then occupant of the premises with respect to which Tenant
     shall have so exercised such right wrongfully fails to deliver possession
     of such premises at the time when its tenancy is scheduled to expire,
     commencement of the term of Tenant's occupancy and lease of such additional
     space shall, in the event of such holding over by such occupant, be
     deferred until possession of the additional space is delivered to Tenant.
     The failure of the then occupant of such premises to so vacate shall not
     constitute a default or breach by Landlord and shall not give Tenant any
     right to terminate this Lease or to deduct from, offset against or withhold
     Annual Fixed Rent or additional rent (or any portions thereof).

15.  (A)  Tenant warrants and represents that Tenant has not dealt with any
     broker in connection with the consummation of this First Amendment other
     than Trammell Crow Company (the "Broker") and in the event any claim is
     made against Landlord relative to dealings by Tenant with brokers other
     than the Broker, Tenant shall defend the claim against Landlord with
     counsel of Tenant's selection first approved by Landlord (which approval
     will not be unreasonably withheld) and save harmless and indemnify Landlord
     on account of loss, cost or damage which may arise by reason of such claim.

     (B)  Landlord warrants and represents that Landlord has not dealt with any
     broker in connection with the consummation of this First Amendment other
     than the Broker and in the event any claim is made against Tenant relative
     to dealings by Landlord with brokers other than the Broker, Landlord shall
     defend the claim against Tenant with counsel of Landlord's selection and
     save harmless and indemnify Tenant on account of loss, cost or damage which
     may arise by reason of such claim.

16.  Except as otherwise expressly provided herein, all capitalized terms used
     herein without definition shall have the same meanings as are set forth in
     the Lease.

17.  Except as herein amended the Lease shall remain unchanged and in full force
     and effect. All references to the "Lease" shall be deemed to be references
     to the Lease as herein amended.

     statement (and the prospectus included therein) and, in the case of the
     accountants' comfort letter, with respect to events subsequent to the date
     of such financial statements, as are customarily covered in opinions of
     issuer's counsel and in accountants' comfort letters delivered to
     underwriters in underwritten Public Offerings of securities and, in the

     to state any material fact required to be stated therein or necessary to
     make the statements therein not misleading in the light of the
     circumstances under which they were made, and, at the request of any such
     seller of Registrable Securities, promptly prepare and furnish to it a
     reasonable number of copies of a supplement to or an amendment of such
     prospectus as may be necessary so that, as thereafter delivered to the
     purchasers of such securities, such prospectus, as supplemented or amended,

     if the listing of such Registrable Securities is then permitted under the
     rules of such exchange or automated quotation system;

would exceed the aggregate number of shares which could be sold in such offering
within a price range acceptable to the Company and the Requesting Holders owning
a majority of the number of shares of the Registrable Securities requested to be
included in such registration (such writing to state the basis of such opinion
and the approximate aggregate number of shares of Registrable Securities, if
any, which may be included in such offering without such effect), then the

registration request shall have been made; PROVIDED, HOWEVER, that no such
reduction shall reduce the amount of Registrable Securities of the Requesting
Holders included in the registration below nineteen percent (19%) of the total
amount of securities included in such registration, unless such Public Offering
is the Company's Initial Public Offering and such registration does not include
securities of any other selling securityholders, in which event any or all of
the registrable Securities of the Requesting Holders may be excluded in
accordance with the first part of this sentence. Any Requesting Holder may
withdraw its request to have all or any portion of its Registrable Securities
included in such offering by notice to the Company within ten (10) days after

Section.

such underwriters and any such holder, at its option, may require that any or
all of the representations and warranties by, and the other agreements on the
part of, the Company to and for the benefit of such underwriters shall also be
made to and for the benefit of such holders and that any or all of the
conditions precedent to the obligations of such underwriters under such
underwriting agreement be conditions precedent to the obligations of such
holders. No such holder shall be required to make any representations or
warranties to or agreements with the Company or the underwriters other than

underwritten offering pursuant to this Agreement, not to effect any public sale
or distribution of any securities of the Company issued after the date hereof

pursuant to Section 2 hereof has become effective and until the later of the
date on which the Public Offering to which such registration relates is
completed or ninety (90) days after the effective date of such underwritten
registration, except as part of such underwritten registration, provided that

or proceedings, whether commenced or threatened, in respect thereof), joint or
several, and expenses, including, without limitation, the reasonable fees,
disbursements and other charges of legal counsel and reasonable costs of
investigation, to which such Company Indemnitee may become subject under the
Securities Act or otherwise (collectively, a "Loss" or "Losses"), insofar as
such Losses 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 securities were registered or otherwise offered or sold under
the Securities Act or otherwise, any preliminary prospectus, final prospectus or
summary prospectus contained therein, or any amendment or supplement thereto
(collectively, "OFFERING DOCUMENTS"), any omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein in the light of the circumstances in which they were made not
misleading or any violation or alleged violation by the Company of the
Securities Act, the Exchange Act, any state securities law or any rule or
regulation promulgated under the Securities Act, the Exchange Act or any state
securities law in connection with the offering covered by such Offering
Documents; PROVIDED THAT, the Company shall not be liable in any such case to
the extent that any such Loss arises out of or is based upon an untrue statement
or alleged untrue statement or omission or alleged omission made in such
Offering Documents in reliance upon and in strict conformity with written
information furnished to the Company by or on behalf of such Company Indemnitee
specifically stating that it is expressly for use therein; and PROVIDED FURTHER,
that the Company shall not be liable to any Person who participates as an
underwriter in the offering or sale of Registrable Securities or any other
Person, if any, who Controls such underwriter in any such case to the extent
that any such Loss arises out of such Person's failure to send or give a copy of
the final prospectus, as the same may be then supplemented or amended, to the
Person asserting an untrue statement or alleged untrue statement or omission or
alleged omission at or prior to the written confirmation of the sale of
Registrable Securities to such Person if such statement or omission was
corrected in such final prospectus (provided that the Company has timely
delivered a final prospectus in accordance with Section 4 above). Such indemnity
shall remain in full force and effect regardless of any investigation made by or
on behalf of such Company Indemnitee and shall survive the transfer of such
securities by such Company Indemnitee.

          (b)  INDEMNIFICATION BY THE OFFERORS AND SELLERS. In connection with
any registration statement filed by the Company pursuant to Section 2 hereof in
which a Securityholder has registered for sale Registrable Securities, each such
holder or seller of Registrable Securities shall, and hereby agrees to,
indemnify and hold harmless the Company and each of its directors and officers
and each other Person, if any, who Controls the Company (each, a "SECURITYHOLDER
INDEMNITEE" for purposes of this Section 7(b)), against all Losses insofar as
such Losses arise out of or are based upon any untrue statement or alleged
untrue statement of a material fact contained in any Offering Documents, any
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein in the light of
circumstances in which they were made not misleading, if such untrue statement
or alleged untrue statement or omission or alleged omission was made in reliance
upon and in strict conformity with written information furnished to the Company
by such holder or seller of Registrable Securities specifically stating that it
is expressly for use therein or any violation or alleged violation by any such
holder or seller of Registrable Securities of the Securities Act, the Exchange
Act, any state securities law or any rule or regulation promulgated under the
Securities Act, the

                                       10
<Page>

Exchange Act or any state securities law in connection with the offering covered
by such Offering Documents; PROVIDED HOWEVER, that the liability of such
indemnifying party under this Section 7(b) shall be limited to the amount of the
net proceeds received by such indemnifying party in the offering giving rise to
such liability. Such indemnity shall remain in full force and effect, regardless
of any investigation made by or on behalf of the Securityholder Indemnitee and
shall survive the transfer of such securities by such holder of Registrable
Securities.

          (c)  NOTICES OF LOSSES, ETC. Promptly after receipt by an indemnified
party of notice of the commencement of any action or proceeding involving a Loss
referred to in the preceding subsections of this Section 7, such indemnified
party will, if a claim in respect thereof is to be made against an indemnifying
party, give written notice to the latter of the commencement of such action;
PROVIDED HOWEVER, that the failure of any indemnified party to give notice as
provided herein shall not relieve the indemnifying party of its obligations
under the preceding subsections of this Section 7, except to the extent that the
indemnifying party is actually prejudiced by such failure to give notice. In
case any such action is brought against an indemnified party, the indemnifying
party shall be entitled to participate in and, unless in such indemnified
party's reasonable judgment, based upon the written advice of its counsel, a
conflict of interest between such indemnified and indemnifying parties may exist
in respect of such Loss, to assume and control the defense thereof, in each case
at its own expense, jointly with any other indemnifying party similarly
notified, to the extent that it may wish, with counsel reasonably satisfactory
to such indemnified party, and after its assumption of the defense thereof, the
indemnifying party shall not be liable to such indemnified party for any legal
or other expenses subsequently incurred by the latter in connection with the
defense thereof other than reasonable costs of investigation. No indemnifying
party shall be liable for any settlement of any such action or proceeding
effected without its written consent, which consent shall not be unreasonably
withheld, delayed or conditioned. No indemnifying party shall, without the
consent of the indemnified party, which consent shall not be unreasonably
withheld, delayed or conditioned, 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 of such Loss or which requires action on the part of
such indemnified party or otherwise subjects the indemnified party to any
obligation or restriction to which it would not otherwise be subject.

          (d)  CONTRIBUTION. If the indemnification provided for in this Section
7 shall for any reason be unavailable to an indemnified party under subsection
(a) or (b) of this Section 7 in respect of any Loss, then, in lieu of the amount
paid or payable under subsection (a) or (b) of this Section 7, the indemnified
party and the indemnifying party shall contribute to the aggregate Losses
(including legal or other expenses reasonably incurred in connection with
investigating the same) (i) in such proportion as is appropriate to reflect the
relative fault of the Company and the prospective sellers of Registrable
Securities covered by the registration statement which resulted in such Loss or
action in respect thereof, with respect to the statements, omissions or action
which resulted in such Loss or action in respect thereof, as well as any other
relevant equitable considerations, or (ii) if the allocation provided by clause
(i) above is not permitted by applicable law, in such proportion as shall be
appropriate to reflect the relative benefits received by the Company and such
prospective sellers from the offering of the securities covered by such

                                       11
<Page>

registration statement; PROVIDED THAT, for purposes of this clause (ii), the
relative benefits received by the prospective sellers shall be deemed not to
exceed the amount received by such prospective sellers. No Person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any Person who was not
guilty of such fraudulent misrepresentation. The obligations, if any, of the
selling holders of Registrable Securities to contribute as provided in this
subsection (d) are several in proportion to the relative value of their
respective Registrable Securities covered by such registration statement and not
joint. In addition, no Person shall be obligated to contribute hereunder any
amounts in payment for any settlement of any action or Loss effected without
such Person's consent, which consent shall not be unreasonably withheld, delayed
or conditioned.

          (e)  OTHER INDEMNIFICATION. The Company and each holder who has
registered for sale Registrable Securities shall, with respect to any required
registration or other qualification of securities under any Federal or state law
or regulation of any governmental authority other than the Securities Act,
indemnify Securityholder Indemnitees and Company Indemnitees, respectively,
against Losses, or, to the extent that indemnification shall be unavailable to a
Securityholder Indemnitee or Company Indemnitee, contribute to the aggregate
Losses of such Securityholder Indemnitee or Company Indemnitee in a manner
similar to that specified in the preceding subsections of this Section 7 (with
appropriate modifications).

          (f)  INDEMNIFICATION PAYMENTS. The indemnification and contribution
required by this Section 7 shall be made by periodic payments of the amount
thereof during the course of any investigation or defense, as and when bills are
received or any Loss is incurred.

     8.   REGISTRATION RIGHTS TO OTHERS.

     If the Company shall at any time hereafter, provide to any holder of any
securities of the Company rights with respect to (i) the registration of such
securities under the Securities Act or the Exchange Act or (ii) the preparation
of an offering document for use in connection with the offer and sale thereof,
(A) such rights shall not be in conflict with or adversely affect any of the
rights provided in this Agreement to the holders of Registrable Securities and
(B) if such rights provided on terms or conditions in the aggregate more
favorable to such holder than the terms and conditions provided in this
Agreement, the Company shall provide (by way of amendment to this Agreement or
otherwise) such more favorable terms or conditions to the holders of Registrable
Securities under this Agreement.

     9.   ADJUSTMENTS AFFECTING REGISTRABLE SECURITIES.

     The Company shall not effect or permit to occur any combination,
subdivision or reclassification of Registrable Securities that would materially
adversely affect the ability of the holders of Registrable Securities to include
such Registrable Securities in any registration of its securities under the
Securities Act contemplated by this Agreement or the marketability of such
Registrable Securities under any such registration or other offering.

     10.  RULE 144 AND RULE 144A.

     After the Company has completed its initial Public Offering, the Company
shall take all actions reasonably necessary to enable holders of Registrable
Securities to sell such securities

                                       12
<Page>

without registration under the Securities Act within the limitation of the
exemptions provided by (a) Rule 144 under the Securities Act, as such Rule may
be amended from time to time, (b) Rule 144A under the Securities Act, as such
Rule may be amended from time to time, or (c) any similar rules or regulations
hereafter adopted by the commission, including, without limiting, the generality
of the foregoing, filing on a timely basis all reports required to be filed
under the Exchange Act. Upon the request of any holder of Registrable
Securities, the Company shall deliver to such holder a written statement as to
whether it has complied with such requirements.

     11.  AMENDMENTS AND WAIVERS.

     This Agreement may be amended and the Company may take any action herein
prohibited, or omit to perform any act herein required to be performed by it,
only if the Company shall have obtained the written consent to such amendment,
action or omission to act, of the holder or holders of at least 66-2/3% of the
aggregate number of shares of the Registrable Securities affected by such
amendment, action or omission to act (and, in the case of any amendment which
modifies, or any action or omission to act which is in contravention of, any of
the provisions of Section 3 or this Section 11 or as to the percentages of
holders required for any action or omission to perform any act hereunder, or any
amendment, action or omission to act which adversely affects any holder (or
former holder) of Registrable Securities, the written consent of each holder (or
former holder) so affected). The Company must consent to any amendment to this
Agreement.

     12.  NOMINEES FOR BENEFICIAL OWNERS.

     In the event that any Registrable Securities are held by a nominee for the
beneficial owner thereof, the beneficial owner thereof may, at its election in
writing delivered to the Company, be treated as the holder of such Registrable
Securities for purposes of any request or other action by any holder or holders
of Registrable Securities pursuant to this Agreement or any determination of the
aggregate number of shares of the Registrable Securities held by any holder or
holders of Registrable Securities contemplated by this Agreement. If the
beneficial owner of any Registrable Securities so elects, the Company may
require assurances reasonably satisfactory to it of such owner's beneficial
ownership of such Registrable Securities.

     13.  ASSIGNMENT.

     The provisions of this Agreement shall be binding upon and inure to the
benefit of the parties hereto and their respective heirs, successors and
assigns. Any Securityholder may assign to any Transferee (as permitted under
applicable law) of its Registrable Securities its rights and obligations under
this Agreement, provided that such Transferee shall agree in writing with the
parties hereto prior to the assignment to be bound by this Agreement as if it
were an original signatory hereto, whereupon such assignee shall for all
purposes be deemed to be a Securityholder under this Agreement. The Company may
not assign this Agreement or any right, remedy, obligation or liability arising
hereunder or by reason hereof.

     14.  CALCULATION OF PERCENTAGE INTERESTS IN REGISTRABLE SECURITIES. For
purposes of this Agreement, all references to an aggregate number of shares of
the Registrable Securities shall be calculated based upon the aggregate number
of shares of the Registrable Securities outstanding

                                       13
<Page>

at the time such calculation is made (including any Registrable Securities that
are issuable upon the conversion or exercise of any outstanding securities of
the Company) and shall exclude any Registrable Securities owned by the Company
or any Affiliate of the Company.

     15.  BASIC FINANCIAL INFORMATION AND REPORTING.

          (a)  The Company will maintain true books and records of account in
which full and correct entries will be made of all its business transactions
pursuant to a consistent system of accounting established and administered by
the Company's treasurer in consultation with the Company's independent certified
public accountants.

          (b)  As soon as practicable after the end of each fiscal year of the
Company, and in any event within ninety (90) days thereafter, the Company will
furnish to each holder of Registrable Securities a consolidated balance sheet of
the Company, as at the end of such fiscal Year, and a consolidated statement of
income and expenses of the Company, for such year, all prepared in accordance
with generally accepted accounting practices consistently applied, and setting
forth in each case in comparative form the figures for the previous fiscal year,
all in reasonable detail. Such financial statements shall be compiled by the
Company's regular independent public accountant or another accountant selected
by the Board of Directors.

          (c)  The company will furnish to each holder of Registrable
Securities, as soon as possible after the end of the first, second and third
quarterly accounting periods in each fiscal Year of the Company, and in any
event within forty-five (45) days thereafter, a consolidated balance sheet of
the Company, as at the end of each such quarterly period, and a consolidated
statement of income and expenses of the Company, for such period and for the
current fiscal year to date, prepared by the Company treasurer in consultation
with the Company's independent certified public accountants.

agrees that monetary damages would not be adequate compensation for any loss
incurred by reason of a breach by it of the provisions of this Agreement and the
Company hereby agrees to waive the defense in any action for specific
performance that a remedy at law would be adequate.
