                              AGREEMENT OF SUBLEASE

                              W I T N E S S E T H:

            WHEREAS, pursuant to that certain lease agreement by and between
Brighton Landing, LLC (f/k/a B.V. Development, LLC) (the "PRIME LANDLORD") and
Sublandlord dated as of May 25, 2000, as it may be amended from time to time
(the "PRIME LEASE" a copy of which Prime Lease, redacted as appropriate, is
attached hereto as EXHIBIT A), Sublandlord has leased space located at the
Brighton Landing, 20 Guest Street, Brighton, Massachusetts (the "BUILDINGS");

            WHEREAS, Subtenant desires to sublease from Sublandlord, and
Sublandlord desires to sublease to Subtenant, a portion of the aforesaid space
leased to Sublandlord (hereinafter referred to as the "DEMISED PREMISES"); and

            WHEREAS, the parties hereto desire to provide for the subletting of
the Demised Premises on the terms and conditions set forth in this Sublease.

            NOW, THEREFORE, for and in consideration of the mutual covenants and
agreements hereinafter set forth, the parties hereto agree as follows:

            1. Demised Premises. Subject to and contingent upon the written
consent of the Prime Landlord, Sublandlord does hereby sublease to Subtenant,
and Subtenant does hereby sublease from Sublandlord, for the term and upon the
conditions hereinafter provided, the Demised Premises, including the right to
use all common areas as set forth in the Prime Lease. The Demised Premises
consists of (i) approximately 10,455 square feet (the "Initial Premises") of
gross rentable area (the "RENTABLE AREA") on the fourth (4th) floor of the
Building (currently designated Suite 400) and are outlined on EXHIBIT B attached
hereto and made a part hereof; and (ii) an additional approximately 16,159
square feet (the "Additional Premises") of Rentable Area on the fourth floor of
the Building and outlined on EXHIBIT B-1 attached hereto and made a part hereof.

            2. Condition of Demised Premises.

            Sublandlord shall deliver the Demised Premises in broom clean but
otherwise in its "as is" condition. Sublandlord shall not be required to make
any alterations, improvements, repairs or decorations to the Demised Premises
and shall deliver the Demised Premises in its "as is" condition. Subtenant's
possession of the Demised Premises on the Commencement Date (as defined
hereafter) shall be conclusive evidence that the Demised Premises have been
delivered in accordance with the provisions of this Sublease and are acceptable
to Subtenant.

                                     - 1 -
<PAGE>
            Subtenant shall make no structural or non-structural alterations to
the Demised Premises without the prior written consent of Sublandlord and Prime
Landlord, which consent shall not be unreasonably withheld or delayed by
Sublandlord.

            3. Term.

            (a) With respect to the Initial Premises, the term of this Sublease
shall commence on February 15, 2005 (the "COMMENCEMENT DATE") and shall end at
midnight on January 11, 2008, or on such earlier date upon which said term may
expire or be terminated pursuant to any of the conditions or limitations or
other provisions of this Sublease, the Prime Lease or pursuant to law. With
respect to the Additional Premises, the term of this Sublease shall commence on
July 1, 2006 and shall end at midnight on January 11, 2008, or on such earlier
date upon which said term may expire or be terminated pursuant to any of the
conditions or limitations or other provisions of this Sublease, the Prime Lease
or pursuant to law (collectively, the "TERM").

            4. Use. Subtenant shall use and occupy the Demised Premises solely
for general office purposes (including, but not limited to, customer and staff
training, and product demonstrations), and shall comply with all applicable
laws, ordinances, governmental regulations, and all protective covenants and
restrictions of record affecting such use, and all rules and regulations of the
Prime Landlord with respect to the Building.

            5. Base Rent.

            (a) Commencing on the Commencement Date, Subtenant shall pay annual
base rent ("Base Rent") for the term hereby created as follows:

      February 15, 2005 through June 30, 2006: a monthly amount of Twelve
      Thousand Four Hundred Eighty Five and 00/100 Dollars ($12,485.00); and

      July 1, 2006 through January 11, 2008: a monthly amount of Fifty Five
      Thousand Three Hundred Seventy Seven and 11/100 Dollars ($55,377.11).

            (The Base Rent and the Additional Rent (as defined hereafter) are
referred to herein as "RENT"). If the obligation of Subtenant to pay Base Rent
hereunder begins on a day other than on the first day of a month, Base Rent from
such date until the first day of the following month shall be pro-rated at the
rate of one-thirtieth (1/30) of the Base Rent for each day payable in advance.
Subtenant will pay said Base Rent by check made payable to Sublandlord or to
such other party as Sublandlord may designate, at its address provided in the
notice section hereof, or at such other address as Sublandlord may hereafter
designate in writing, in lawful money of the United States, without notice,
demand, set-off or deduction whatsoever, except as otherwise provided in the
Prime Lease, in advance on the first day of each and every calendar month and in
the manner otherwise hereinafter specified.

            6. Security Deposit. Upon execution of this Sublease, Subtenant
shall provide Sublandlord a cash security deposit in the sum of Thirty-eight
Thousand Three Hundred Thirty-Five Dollars ($38,335.00). Upon July 1, 2006,
Subtenant shall provide Sublandlord an additional cash security deposit of
Fifty-nine Thousand Seven Hundred Seventy-six Dollars

                                     - 2 -
<PAGE>
($59,776.00), so as to create a total cash security deposit of Ninety-eight
Thousand One Hundred Thirty-one Dollars ($98,131.00). In the event of any
default by Subtenant hereunder, Sublandlord shall have the right, but shall not
be obligated, to apply, upon three days prior written notice to Subtenant, all
or any portion of the deposit to cure such default, in which event Subtenant
shall be obligated to promptly deposit with Sublandlord that portion of the
deposit used to cure such default. Said security deposit may be mingled with
other funds of Sublandlord and no fiduciary relationship shall be created with
respect to such deposit, nor shall Sublandlord be liable to pay Subtenant
interest thereon. If Subtenant faithfully performs all the covenants and
conditions on its part to be performed, then the security deposit shall be
returned to Subtenant within thirty (30) days after the expiration of the
Sublease.

            Sublandlord and Subtenant hereby agree that in the event of a
default by the Sublandlord under the Prime Lease, Prime Landlord may, in Prime
Landlord's discretion, demand that Sublandlord assign its rights to and interest
in the Security Deposit to Prime Landlord, to be held in trust by Prime Landlord
to secure the performance of the Subtenant under the Sublease.

            7. Additional Rent.

                  (a) Subtenant shall pay, in addition to the Base Rent, its
Proportionate Share (as hereafter defined) of Sublandlord's Share of Excess
Property Taxes and Sublandlord's Share of Excess Operating Costs, pursuant to
Section 4.4 and 4.5 of the Prime Lease as additional rent (which payments, in
addition to those payments set forth in Section 7(b) and any other amounts due
hereunder, are referred to as "ADDITIONAL RENT"). For purposes of calculating
such excess amounts, the term "Operating Cost Base Year" shall be calendar year
2005, and "Property Tax Base Year" shall be fiscal tax year 2005. All payments
due by Subtenant under this Section 7(a) shall be made at least ten (10) days in
advance of the date comparable payments are due by Sublandlord under the Prime
Lease, but no sooner than twenty (20) days after Sublandlord has provided
Subtenant with an invoice and detailed support and calculation of such
Additional Rent. Subtenant's obligations hereunder to the extent accrued prior
to the Sublease expiration date, shall survive the expiration of the Sublease.
From the Commencement Date through June 30, 2006, Subtenant's "PROPORTIONATE
SHARE" with respect to the Demised Premises shall be equal to 10,455 square feet
divided by 54,162 square feet, as set forth in the Prime Lease. From July 1,
2006 through January 11, 2008, Subtenant's Proportionate Share with respect to
the Demised Premises shall be equal to 26,614 divided by 54,162 square feet.

                  (b) Subtenant shall also pay as Additional Rent, commencing on
the Commencement Date, its Proportionate Share of all utility charges incurred
by Sublandlord pursuant to Section 4.3 of the Prime Lease. Subtenant shall pay
such charges within thirty (30) days of receipt of billing from Sublandlord. If
Sublandlord or other subtenants operate any high energy consumption equipment in
excess of standard office equipment, Sublandlord covenants and agrees to adjust
such utility charges, by subtracting the cost of the electricity reasonably
estimated to be used for the operation thereof, prior to calculating Subtenant's
Proportionate Share. If Subtenant operates any high energy consumption equipment
in excess of standard office equipment, Subtenant covenants and agrees to pay,
as an additional charge, the cost of the electricity reasonably estimated to be
used for the operation thereof. In addition, if Subtenant

                                     - 3 -
<PAGE>
requires any heat and air-conditioning during non-business hours, then Subtenant
shall pay any amounts charged by Prime Landlord in accordance with Section 5.1.1
of the Prime Lease. Subtenant shall not be charged the Proportionate Share of
any heat and air-conditioning during non-business hours requested by Sublandlord
or other subtenants. If electric utility service, or any utility service, is
separately metered at any time to the Demised Premises, Subtenant agrees to pay
such separately metered charges directly to the utility provider. The
Proportionate Share of such utility bills owed by Subtenant will be adjusted as
appropriate to reflect any such sub-metering. Sublandlord reserves the right,
but shall be under no obligation, to sub-meter the Demised Premises at any time
during this Sublease.

            8. Obligations Under the Prime Lease. This Sublease and Subtenant's
rights under this Sublease shall at all times be subject to and are made upon
all of the terms, covenants, and conditions of the Prime Lease (except as
otherwise set forth herein), with the same force and effect as if fully set
forth herein at length, the termination (for whatever reason) of which Prime
Lease shall automatically terminate this Sublease. Except as otherwise expressly
provided for herein or as may be inconsistent or in conflict with the terms and
provisions of this Sublease, Subtenant shall keep, observe and perform or cause
to be kept, observed and performed, faithfully all those terms, covenants and
conditions of Sublandlord under the Prime Lease with respect to the Demised
Premises. Notwithstanding the foregoing, where "Premises" or "Lease" or words of
similar import appear in the Prime Lease, the same shall be deemed to mean the
Demised Premises (as defined in this Sublease) and this Sublease, respectively,
and wherever the words "Landlord" and "Tenant" appear in the Prime Lease, the
words shall be deemed to refer to Sublandlord and Subtenant, respectively.

      Notwithstanding the foregoing, the following provisions of the Prime Lease
are hereby expressly excluded and shall not be incorporated in this Sublease:
Sections 2.4, 3.1, 3.2, 3.3, 3.4 (except that the provisions of the first three
(3) paragraphs, to the extent applicable, shall apply to any alterations made by
Subtenant), 3.5, 3.6, 4.2, 6.1.6., 10.11 and Exhibit C and D.

      In addition, to the extent that Sublandlord has any rights or options to
extend or renew the Prime Lease, or any expansion options or right of first
offers, Subtenant shall have no right to exercise such rights or options. In
addition, notwithstanding the provisions of this Section 8 of the Sublease to
the contrary, Sublandlord shall have no obligation to perform or furnish any of
the work, services, repairs or maintenance undertaken to be provided to the
Demised Premises that are made or performed by Prime Landlord under the Lease
(including but not limited to the Prime Landlord's Covenants set forth in
Article V of the Prime Lease) or any other term, covenant or condition required
to be performed by Prime Landlord under the Lease, and for all such services and
rights Subtenant will look solely to Prime Landlord. Furthermore, any
representations made by Prime Landlord in the Prime Lease shall be personal to
Prime Landlord and Sublandlord shall not be liable for any breach thereof.
Subtenant shall not be entitled to any abatement of Rent hereunder as a result
of the failure of Prime Landlord to perform or provide any of the work or
services to be provided by Prime Landlord in respect of the Demised Premises.

                                     - 4 -

            9. Insurance.

                  (a) Subtenant shall obtain and at all times during the term
hereof maintain, at its sole cost and expense, policies of insurance required by
Section 6.1.8 of the Prime Lease.

                  (b) Subtenant shall deliver to Sublandlord and Prime Landlord
certificates of such insurance at the beginning of the term of this Sublease,
and thereafter certificates of renewal thereof not less than thirty (30) days
prior to the expiration of any such policy. In the event that Subtenant shall
fail promptly to furnish any insurance herein required, and provided Sublandlord
delivers to Subtenant at least three business days prior written notice and an
opportunity to cure, Sublandlord may effect the same and pay the premium
therefor for a period not exceeding one (1) year of the expiration hereof, and
the premium so paid by Sublandlord shall be payable by Subtenant to Sublandlord
within five (5) business days of receipt by Subtenant of notice of payment
thereof from Sublandlord.

                  (c) All policies of insurance as aforesaid shall name both
Sublandlord and the Prime Landlord as additional insureds, as their interests
may appear, and include a clause waiving the rights of subrogation against Prime
Landlord and Sublandlord.

            10. Defaults. If Subtenant shall (i) fail to pay when due any Rent
or other sums due hereunder, or (ii) fail to faithfully perform any other
obligation under this Sublease, or (iii) default under Article IX of the Prime
Lease, then Subtenant shall be in default of this Sublease and Sublandlord shall
have all of the rights and remedies accorded to the Prime Landlord under the
Prime Lease and Subtenant shall have all of the rights and protections accorded
Sublandlord under the Prime Lease (except as otherwise set forth in this
Sublease). Subtenant further agrees to reimburse Sublandlord for all costs and
expenses, including reasonable attorneys' fees, incurred by Sublandlord in
asserting its rights hereunder against Subtenant or any other party claiming by,
through or under Subtenant.

            11. Subordination. This Sublease is subject and subordinate to the
Prime Lease, to all ground and underlying leases, and to all mortgages and deeds
of trust which may now or hereafter affect such leases, the leasehold estate or
estates thereby created or the real property of which the Demised Premises form
a part, and to any and all renewals, modifications, consolidations, replacements
and extensions thereof.

            12. Assignments and Further Subleases.

                  (a) Subtenant agrees that it will not assign or encumber, or
permit to be encumbered, its rights or interests under this Sublease, nor sublet
the whole or any part of the Demised Premises, directly or indirectly, by
operation of law or otherwise, without the prior written consent of Sublandlord
and Prime Landlord. Sublandlord agrees that it shall not unreasonably withhold
or delay its consent to any proposed assignment or sublet, provided that the
proposed assignment or sublet complies with all conditions set forth in the
Prime Lease. Subtenant shall reimburse Sublandlord promptly for its reasonable,
out-of-pocket, legal and other expenses incurred by Sublandlord in connection
with any request by Subtenant for consent to assignment or subletting. Subtenant
further agrees that, notwithstanding any assignment or

                                     - 5 -
<PAGE>
sublease, Subtenant shall remain fully liable for the payment of Rent and
Additional Rent and for the other obligations of this Sublease on the part of
Sublessee to be performed or observed.

            (b) Provided that Subtenant is not in default of any monetary
obligation hereunder (after the expiration of any applicable grace, notice or
cure period), in the event Subtenant subleases or assigns all or part of the
Demised Premises to a tenant pursuant to Section 12 (a) above, and, after
deducting all reasonable expenses incurred by Subtenant in connection with such
sublease or assignment (including attorneys fees, brokerage commissions, tenant
improvements paid by Subtenant and rent concessions) said tenant is obligated to
pay Subtenant more in any month than Subtenant is obligated to pay Sublandlord
under this Sublease, then Subtenant shall pay Sublandlord fifty percent (50%) of
the amount by which Subtenant's net rent received from said tenant after any
reasonable associated transaction expense incurred in connection with said
subletting or assignment exceed the Subtenant's payment obligations hereunder.

            13. Quiet Enjoyment and Consent of Prime Landlord. Sublandlord
covenants and agrees with Subtenant that, upon Subtenant paying the rent
reserved in this Sublease and observing and performing all the terms, covenants
and conditions of this Sublease on Subtenant's part to be observed and
performed, Subtenant may peaceably and quietly enjoy the Demised Premises during
the term of this Sublease free from any claim by Sublandlord or persons claiming
under Sublandlord, in accordance with the terms, covenants and conditions of
this Sublease.

            14. Indemnification. Subtenant hereby agrees to indemnify and hold
Sublandlord and the Prime Landlord harmless from and against any cost, damage,
claim, liability or expense (including reasonable attorney's fees) incurred by
or claimed against Sublandlord and the Prime Landlord, directly or indirectly,
as a result of (i) any act, event or occurrence in or about the Buildings caused
by Subtenant, Subtenant's employees or guests, (ii) Subtenant's breach of any of
its covenants under this Sublease, (iii) the use or occupancy of the Buildings
by Subtenant or any person using or occupying the Buildings under or through
Subtenant, or (iv) any act, omission, negligence or misconduct of Subtenant, or
of any person using or occupying the Buildings under or through Subtenant or of
any contractor, employee, agent or visitor of Subtenant in or about the property
of which the Buildings are a part.

            Sublandlord hereby agrees to indemnify and hold Subtenant harmless
from and against any costs, damage, claim, liability or expense (including
reasonable attorney's fees) incurred by or claimed against Subtenant, directly
or indirectly, caused by Sublandlord or Sublandlord's contractors, employees,
agents or visitors' negligence or willful misconduct.

            15. Notices. Any notice, demand or other communication which must or
may be given or made by either party hereto shall be in writing and shall be
given or made by hand delivery, commercial courier, against receipt, or by
mailing the same by registered or certified mail, postage prepaid, addressed:

Either party may, by notice to the other given as aforesaid, designate a new or

thereafter shall be given, made or mailed. Any notice, demand or communication
given hereunder shall be deemed delivered when actually received.

            16. Surrender. Upon the expiration of the Term, provided that
Subtenant has not entered into a direct lease of the Demised Premises with the
Prime Landlord which direct term commences as of the expiration of the Term,
Subtenant shall quit and surrender to Sublandlord the Demised Premises
(including the furnishings, phone systems and any other items, if any, owned by
Sublandlord and which Subtenant used throughout the Term), broom clean and in
the same order and condition as they were on the Commencement Date, ordinary
wear and casualty excepted, and Subtenant shall remove from the Demised Premises
all of its personal property, furnishing and trade fixtures. Subtenant's
obligations to perform and observe this covenant shall survive the expiration or
other termination of the term of this Sublease.

            17. Holdover. In the event Subtenant shall not immediately surrender
the Demised Premises upon the expiration of the Term, and provided that
Subtenant has not entered into a direct lease of the Demised Premises with the
Prime Landlord which direct term commences as of the expiration of the Term,
Subtenant shall become a tenant-at-sufferance at one hundred seventy-seven

made against Sublandlord resulting from Sublandlord's delay in delivering
possession of the Demised Premises to Prime Landlord, including but not limited
to any holdover rent over and above the rent due under the first sentence of
this section that Sublandlord is required to pay Prime Landlord pursuant to the
terms of the Prime Lease.

            18. Sublandlord's Compliance with Prime Lease. Sublandlord agrees to
pay all rents and other sums required of it, and comply with all other
provisions of the Prime Lease. Sublandlord hereby represents and warrants that
the Prime Lease (a) is presently in full force and effect, and has not been
amended or modified, (b) there is presently no outstanding default in the
payment of rent or other sums due under the Prime Lease and (c) to the best of
Sublandlord's knowledge, there is presently no outstanding breach or default of
the Prime Lease by either Sublandlord or Prime Landlord.

      Subtenant agrees that in any case where the provisions of this Sublease
require the consent or approval of Sublandlord prior to the taking of any
action, it shall be a condition precedent to the taking of such action that the
prior consent or approval of Prime Landlord shall have been

                                     - 8 -
<PAGE>
obtained if Prime Landlord's consent must be obtained under the Prime Lease in
such cases. In the event Prime Landlord's consent is so obtained, Sublandlord
agrees that its consent shall not be unreasonably withheld, delayed or
conditioned except as otherwise provided herein. Sublandlord agrees that it
shall use commercially reasonable efforts to obtain Prime Landlord's consent in
such circumstances (provided that in no event shall Sublandlord be required to
compensate Prime Landlord to obtain such consent), but otherwise shall not have
any duty or responsibility with respect to obtaining the consent or approval of
Prime Landlord.

            19. Casualty and Taking. In the event of any taking by eminent
domain or damage by fire or other casualty to the Demised Premises thereby
rendering the Demised Premises wholly or in part untenantable, Subtenant shall
acquiesce in and be bound by any action taken by or agreement entered into
between Prime Landlord and Sublandlord with respect thereto. In addition, in the
event of any taking by eminent domain or damage by fire or other casualty to the
Demised Premises, Subtenant shall be entitled to terminate this Sublease if, and
to the extent, that Sublandlord has such termination rights in the Prime Lease
with respect to the Demised Premises, provided, however, that Subtenant must
provide notice of any such termination twenty (20) days earlier than required to
be given by Sublandlord to Prime Landlord under the terms of the Prime Lease,
but no sooner than ten (10) days after written notice of such taking is provided
to Subtenant by Sublandlord.

            20. Broker. Subtenant warrants that it has had no dealings with any
broker or agent in connection with this Sublease except for Meredith & Grew,
Inc. and NAI Hunneman. Subtenant covenants to pay, hold harmless and indemnify
Sublandlord from and against any and all costs, expense or liability for any
compensation, commissions and charges claimed by and broker or agent other than
the broker designated in this Section with respect to this Sublease or the
negotiation thereof arising from a breach of the foregoing warranty. Sublandlord
shall be responsible for payment of any brokerage commission to the broker
designated in this Section pursuant to separate agreement.

            21. Furniture, Equipment. The Demised Premises shall be delivered to
Subtenant with all furniture, equipment and wiring currently located therein,
and Subtenant shall have the use of said furniture, equipment and wiring for the
duration of the Term at no additional charge. An inventory of the furniture and
equipment currently located in the Demised Premises is set forth on EXHIBIT C.
Sublandlord makes no representations or warranties that the existing furniture,
equipment or wiring is sufficient for Subtenant's business purposes, and
Subtenant accepts such furniture, equipment and wiring in its "as is" condition.
The furniture, equipment and wiring shall remain the property of Sublandlord. At
the expiration of the Term, or earlier termination thereof, all furniture,
equipment and wiring shall be delivered to Sublandlord in the same condition as
of the date of this Sublease, reasonable wear and tear excepted.

                          AMENDED AND RESTATED SUBLEASE

This amended and restated sublease (the "Restated Sublease") is made and entered
into by and between CHORDIANT SOFTWARE, INC., a Delaware corporation
(hereinafter, "Sublessor") and AMICAS, INC., a Delaware corporation
(hereinafter, "Sublessee"), and amends and restates the existing sublease
entered into by the parties on May 31, 2002 (the "Existing Sublease").

      Reference is hereby made to that certain lease (the "Overlease") between
B.V. Development, LLC, (hereinafter, "Overlandlord") as lessor and Prime
Response, Inc., a predecessor in interest to Sublessor, as lessee, dated as of
June 9, 2000, and demising approximately 16,308 rentable square feet (as defined
in the Overlease) on the second floor of the building at 20 Guest Street, Boston
(Brighton), Massachusetts (the "Premises").

      WHEREAS Sublessor is desirous of subleasing the Premises to Sublessee; and

      WHEREAS Sublessee is desirous of subleasing the Premises from Sublessor.

      NOW THEREFORE, in consideration of the premises and mutual covenants
herein set forth and for one dollar and other valuable consideration, each party
hereto to the other paid, the receipt and sufficiency of which is hereby
acknowledged, Sublessor and Sublessee hereby agree as follows:

            1. Sublessor hereby leases to Sublessee and Sublessee hereby hires
and takes from Sublessor the Premises and the various rights appurtenant thereto
as set forth in the Overlease except as and to the extent hereinafter set forth
for an original term commencing June 1, 2002, and ending May 31, 2005 (the
"Original Term") and for an extended term commencing June 1, 2005, and ending
July 31, 2006 (the "Extended Term") unless earlier terminated pursuant hereto or
to the terms of the Overlease. Sublessee acknowledges that a termination of the
Overlease for any reason whatsoever shall constitute a termination of this
Restated Sublease on the same date and that in the event of any such termination
Sublessee shall have no recourse whatever against Sublessor for damages or
otherwise on account thereof except only and to the extent that such termination
has been caused by the default of the Sublessor under the Overlease.

            2. Provided Sublessee is not in default hereunder, beyond applicable
grace and/or cure periods, either at the time of the giving of the following
described notice or at the commencement of the Second Extended Term (hereinafter
defined) and provided the Overlease is still in effect, Sublessee shall have the
right, upon written notice to Sublessor given at least six months prior to the
end of the Extended Term, to extend the term for a further period of seventeen
(17) months through December 31, 2007 (the "Second Extended Term") upon all of
the same terms and conditions applicable to the Extended Term except that the
rent during the Second Extended Term for the Premises shall be at the rate of
$407,700 per annum during the Second Extended Term, payable $33,975.00 per month
on the first day of each month during the Second Extended Term.

            3. Sublessee shall pay to Sublessor rent (i) at the rate of
$326,160.00 per annum for the first twelve months of the Original Term, payable
$27,180.00 per month on the first day of each said first twelve months; (ii) at
the rate of $334,314.00 per annum for the second twelve months of the Original
Term, payable $27,859.50 per month on the first day of each of
<PAGE>
said second twelve months of the Original Term; and (iii) at the rate of
$342,468.00 per annum for the third twelve months of the Original Term, payable
$28,539.00 per month on the first day of each of said third twelve months of the
Original Term except only that the rent for the first full month of the term of
this Sublease shall be paid, together with the security deposit referred to
below, on the execution date hereof. Sublessee shall pay to Sublessor rent at
the rate of $366,930.00 per annum during the Extended Term, payable $30,577.50
per month on the first day of each month of the Extended Term. Rent for any
fraction of a month at the end of the term shall be proportionately pro-rated.
All rent and all other sums payable by Subleasee hereunder or in connection
herewith shall be paid when due directly to Sublessor and shall not be paid to
the Overlandlord or any other party unless Sublessor specifically directs
Sublessee to the contrary in writing. Sublessor covenants and agrees to perform
all obligations of the lessee under the Overlease except only for those which
are the obligation of the Sublessee pursuant hereto; however, Sublessor agrees
to pay when due or within any grace period allowed therefor all rent and other
sums which are due to the Overlandlord under the Overlease.

            4. Sublessee will pay directly to the utility (or other supplier)
when due all charges for electricity supplied to the Premises.

            5. Sublessee shall have the right during the Original Term, the
Extended Term and (if exercised) the Second Extended Term to use in the Premises
the furniture of Sublessor listed on the inventory thereof attached hereto
without charge therefor; however, at the end of the term hereof Sublessee shall
leave said furniture in the condition in which it was at the beginning of the
Original Term, reasonable wear and tear excepted, the risk of casualty loss
being that of Sublessee.

            6. Sublessee shall have the right during the Original Term, the
Extended Term and (if exercised) the Second Extended Term to use the existing
telephone wires, handsets and related apparatus of Sublessor in the Premises
(the "Telephone System") without charge therefor, such right of use being given
"as is" and "where is" and without representation or warranty as to the
condition thereof and without obligation on the part of the Sublessor to perform
any maintenance or make any repair thereto. At the end of the term hereof
Sublessee shall leave the telephone system in the condition it was in at the
beginning of the Original Term, reasonable wear and tear excepted, the risk of
casualty loss being that of Sublessee.

            7. Sublessor acknowledges having received from Sublessee at the
beginning of the Original Term the sum of $54,360.00 (the "Security Deposit") to
be held by Sublessor, without interest, as security for the performance by
Sublessee of its obligations hereunder during the Original Term, the Extended
Term and, if exercised, the Second Extended Term, which Security Deposit shall
be returned to Sublessee within thirty (30) days after the termination of this
Sublease, provided there then exists no breach or default of any obligation of
Sublessee. If all or any part of the Security Deposit is applied to an
obligation of Sublessee hereunder, Sublessee shall immediately upon request by
Sublessor restore the Security Deposit to its original amount. Sublessee shall
not have the right to call upon Sublessor to apply all or any part of the
Security Deposit to cure any default or fulfill any obligation of Sublessee,
such use being solely in the discretion of Sublessor. Upon any transfer by
Sublessor of its interest under this Restated Sublease, the Security Deposit may
be delivered by Sublessor to Sublessor's transferee.

                                       2

            8. Sublessor and Sublessee each represent and warrant to the other
they have not dealt with any broker or other party entitled to a commission
(other than Robert F. Fitzgerald, Jr. and/or Ellen Fantini of Grubb & Ellis and
Stephen A. James and/or Thomas Aitken of NAI/Hunneman Commercial Company) in the
negotiation and consummation of this Sublease; and in the event of any brokerage
claims against either party predicated upon or arising out of any such dealings,
the party having had such dealings shall defend the other and indemnify and hold
the other harmless from and against all such claims. The commissions due Grubb &
Ellis and NAI/Hunneman Commercial Company shall be the obligation of Sublessor.

            9. This Restated Sublease and all of the rights of the Sublessee
hereunder (notwithstanding that this Sublease may have been executed by the
parties hereto) are subject to, and shall have no force and effect whatever
unless and until the Overlandlord consents in writing to both this Restated
Sublease and a contemporaneous fully executed Sublease between Sublessee and
PatientKeeper, Inc. for space on the fourth floor of the building at 20 Guest
Street, Boston (Brighton), Massachusetts. Sublessor agrees promptly upon the
execution hereof to request such consent from the Overlandlord pursuant to
Section 6.1.6 of the Overlease. In making such request Sublessor will request
Overlandlord to agree to send to Sublessee a copy of any notice of default under
the Overlease sent to Sublessor; however, Sublessor makes no representation or
warranty that Overlandlord will so agree. In the event the Overlandlord requires
any reimbursement for legal or other fees incurred by Overlandlord in connection
with such consent pursuant to said Section 6.1.6, Sublessor shall pay such fees.
In the event Overlandlord has not consented in writing to this Sublease within
thirty days from the date hereof either party may terminate this Restated
Sublease by written notice to the other given prior to Sublessor's receipt of
such consent from Overlandlord. In such event such termination shall be
Sublessee's only remedy.

            10. By its execution hereof, Sublessee acknowledges that it accepts
the Premises "as is" and in their present condition and state of repair.

            11. It is agreed that the relationship between, and the rights of
Sublessor and Sublessee shall with respect to enforcement of the provisions of
this Restated Sublease and termination hereof be governed by Article IX of the
Overlease as if they were Landlord and Tenant respectively. Further, Sublessee
shall pay all of Sublessor's actual, out-of-pocket costs of enforcing this
Restated Sublease, including reasonable attorneys' fees. For the purposes of
this paragraph 11, "Annual Rent" shall mean, during the Original Term and the
Extended Term, the rent referred to in paragraph 3 hereof; during the Second
Extended Term, the rent referred to in paragraph 2 hereof.

            12. Sublessee agrees, from time to time, upon not less than ten (10)
days' prior written request by Sublessor, to execute, acknowledge and deliver to
Sublessor a statement in writing, addressed to such party as Sublessor shall
designate in its notice to Sublessee, certifying that this Restated Sublease is
unmodified and in full force and effect and that the Sublessee has no defenses,
offsets or counterclaims against its obligations to pay the rent and perform its
other covenants under this Restated Sublease (or, if there have been any
modifications that the same is in full force and effect as modified and stating
the modifications and, if there are any defenses, offsets, counterclaims or
defaults, setting them forth in reasonable detail), the dates to which the rent
have been paid and a statement that to the knowledge of Sublessee, but without
having made any particular inquiry, Sublessor is not in default hereunder (or if
in default, stating the nature of

                                       3
<PAGE>
such default in reasonable detail). Any statement delivered pursuant to this
Paragraph 13 may be relied upon by any prospective purchaser or mortgagee of the
Sublease Premises.

            13. Sublessor agrees from time to time, upon not less than ten (10)
days' prior written request by Sublessee, to execute, acknowledge and deliver to
Sublessee a statement in writing, addressed to such party as Sublessee shall
designate in its notice to Sublessor, certifying that this Restated Sublease is
unmodified and in full force and effect (or, if there have been any
modifications that the same is in full force and effect as modified and stating
the nature of such modifications in reasonable detail), the dates to which the
rent has been paid and a statement that to the knowledge of Sublessor, but
without having made any particular inquiry, Sublessee is not in default
hereunder (or if in default, stating the nature of such default in reasonable
detail). Any statement delivered pursuant to this paragraph 13 may be relied
upon by any prospective purchaser of, or party secured by the interest of
Sublessee herein.

            14. The Sublessee agrees not to violate any of the terms and
provisions of the Overlease or do anything that will subject the Overlease to
termination by the Overlandlord under the provisions of the Overlease. The
Sublessor agrees not to do anything that will subject the Overlease to
termination by the Overlandlord under the provisions of the Overlease. In the
event the Overlease is terminated due to the fault of the Sublessor, the
Sublessor shall be liable for all damages to the Overlandlord pursuant to the
terms of the Overlease, but the foregoing shall not limit any liability of
Sublessee to Sublessor for any default of Sublessee hereunder.

            15. Upon reasonable notice and at reasonable times, except in cases
of emergency, in which event no such notice shall be required, Sublessor or its
representatives may enter to view the Premises to assure compliance with the
terms of this Sublease and to show the Premises to prospective purchasers,
lenders and tenants. In so doing Sublessor shall use reasonable efforts to avoid
interfering with the operation of Sublessee's business in the Premises.

            16. Sublessee shall not have any right to assign or further sublease
all or any portion of the Premises or permit any other party to use all or any
portion of the same.

            17. Notices. All notices required or permitted hereunder shall be in
writing and shall be deemed duly served if and when delivered by hand or mailed

      Any of the parties named in this Paragraph 18 may change the address for
notices by written notice sent to each of the other persons at the address as
set forth herein.

            18. If any provision of this Restated Sublease shall to any extent
be determined by any court of competent jurisdiction to be invalid or
unenforceable for any reason, the parties agree to amend this Restated Sublease
so as to effectuate as nearly as reasonably possible the original intent of the
Sublessor and Sublessee. There are no oral or written agreements between
Sublessor and Sublessee affecting this Restated Sublease. This Restated Sublease
may not be amended, altered, or modified except by an instrument in writing
executed by Sublessor and Sublessee; shall be governed by and construed in
accordance with the laws of the Commonwealth of Massachusetts; and shall be
binding upon and inure to the benefit of the parties hereto and their respective
successors and assigns. In no event shall Sublessor ever be liable to Sublessee

            19. The parties acknowledge that pursuant to Section 2.1 of the
Overlease Sublessee will have the right to use forty-seven automobile parking

            20. Except to the extent inconsistent with the terms hereof or
specifically recited herein to the contrary, Sublessee shall have all of the
rights and perform all of the obligations of the tenant under the Overlease and
Sublessor shall have all of the rights of the landlord under the Overlease, all
as therein provided; however with respect to obligations of the landlord under
the Overlease which pursuant to the terms hereof inure to the benefit of the
Sublessee, Sublessor's maximum obligation shall be to use diligent efforts to
require the landlord under the Overlease to perform such obligations after
written notice from Sublessee to Sublessor of such failure to perform such
obligations by the landlord under the Overlease.

      In confirmation thereof it is agreed that the Sublessee shall have no

such notice promptly upon its receipt thereof); 6.1.1; 6.1.6; the second

      As to the following recited Articles and Sections, except as and to the
extent specifically provided below the same shall apply to, and constitute

(this provision being intended to apply to the Original Term, the Extended Term

Sublessee hereunder except that in the event Sublessee holds over at the end of
the term of the Overlease, Sublessee shall pay to Sublessor the full amount
Sublessor is required to pay to the Overlandlord under the Overlease; and
further Sublessee in all events shall be and remain liable for all damages
sustained by the Sublessor on account of such holding over including, without

otherwise was prepared to occupy the Premises after the expiration of the term
of this Sublease); 6.1.6 (and the indemnification and defense provisions thereof
shall apply to Sublessor as well as the Overlandlord); 6.1.7; all portions of
Section 6.2 except that the same shall refer to the execution of this Restated
Sublease rather than the Overlease; 7.1.1; 7.1.2 (however any election to
terminate the Overlease shall be that of Sublessor and not Sublessee); 7.1.3;

                 CONSENT TO SUBLEASE AND FURTHER AGREEMENTS WITH
                                RESPECT THERETO.

      This agreement is made by and between CHORDIANT SOFTWARE, INC., a Delaware
corporation ("Tenant") and BRIGHTON LANDING, LLC (formerly named B.V.
Development, LLC) a Delaware limited liability company ("Overlandlord").

      Reference is hereby made to that certain lease (the "Overlease") from
Overlandlord to Tenant dated June 9, 2000, relating to certain premises (the
"Premises") on the second floor of the building at 20 Guest Street, in the
Brighton section of Boston, Massachusetts. Reference is further made to that
certain amended and restated sublease (the "Restated Sublease") from Tenant to
AMICAS, Inc., a Delaware corporation ("Subtenant") dated March 8th, 2005, under
which the Premises are subleased to the Subtenant. A copy of the Restated
Sublease is attached hereto. In consideration of the premises and the mutual
covenants hereinafter set forth and for one dollar and other valuable
consideration each party hereto to the other paid, the receipt and sufficiency
of which is hereby acknowledged, it is hereby agreed as follows:

      1.    Pursuant to Subsection 6.1.6 of the Overlease the Overlandlord
            hereby consents to the Restated Sublease; however, such consent
            shall not release Tenant from its continuing primary liability under
            the Overlease.

      2.    The Tenant agrees that in the event the Tenant is in default under
            the Overlease for the non-payment of Annual Base Rent, Tenant's
            Share of Excess Property Taxes or Tenant's Share of Excess Operating
            Costs (each as defined in the Overlease and, collectively, "Rent")
            after the giving of any required notice thereof and the lapse of any
            cure period applicable thereto which default tenant does not contest
            on a bona fide basis, then Overlandlord shall have the right while
            such default continues (unless prior to the cure thereof the
            Overlease has been terminated on account thereof) and so long as
            Subtenant is in possession of the Premises to collect all rent then
            and thereafter due from the Subtenant to the Tenant under the
            Restated Sublease and apply such amounts to the unpaid Rent due
            Overlandlord under the Overlease. At the written request of
            Overlandlord, Tenant will notify Subtenant that such payments should
            be paid to Overlandlord.

      3.    If the Overlandlord agrees in writing with the Subtenant to accept
            the Restated Sublease for the balance of its stated term, then
            Tenant shall deliver to Overlandlord the security deposit of
            Subtenant under the Restated Sublease which Tenant then holds, and
            Overlandlord will then hold such security deposit pursuant to the
            terms of the Restated Sublease. In such event upon the delivery of
            the said security deposit to the Overlandlord, Tenant shall
            thereafter be relieved of any responsibility therefor.
