                           PURCHASE AND SALE AGREEMENT

     THIS PURCHASE AND SALE AGREEMENT ("Agreement") is made as of ________,
2002, by and between NAVISITE, INC., a Delaware corporation ("Seller"), and FARM
ASSOCIATES LIMITED PARTNERSHIP, a Massachusetts limited partnership ("Buyer").

     In consideration of the mutual covenants and provisions herein contained
and other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, Seller and Buyer hereby agree as follows:

     1.   Agreement to Buy and to Sell; Premises; Lease.

          (a)  Subject to the terms and conditions in this Agreement, Seller
agrees to sell, assign, convey, and transfer to Buyer, and Buyer agrees to
purchase, all of Seller's right, title and interest in and to the following
(collectively, the "Premises"): the land located in Andover, Massachusetts,
commonly known as 400 Minuteman Road, more particularly described in Exhibit A
hereto and all improvements on that land and all fixtures affixed to the land or
the improvements; all easements appurtenant to that land; and the following
personal property: all cafeteria furniture, desks, tables, chairs, cafeteria
equipment, and all other furniture located on the second floor of the existing
building (including, without limitation, all cubicles, panel furniture, desks,
tables, chairs, shelving and filing cabinets), all of which are in used
condition (collectively, the "Personal Property"). The Premises are part of a
larger development commonly known as Minuteman Park.

          (b)  Concurrently with the closing of this transaction, Seller, as
Tenant, and Buyer, as Landlord, will enter into a lease for a portion of the
Premises (the "Lease") in the form attached hereto as Exhibit "B."

     2.   Purchase Price. The purchase price (the "Purchase Price") to be paid
by Buyer to Seller for the Premises is Ten Million Eight Hundred Fifty-seven
Thousand Four Hundred Dollars ($10,857,400). The Premises is encumbered by an
existing Mortgage securing a loan (the "Loan") made by General American Life
Insurance Company ("Lender") to Seller. Buyer will purchase the Premises subject
to this Mortgage, and at the closing will receive a credit against the Purchase
Price equal to Ten Million Eight Hundred Fifty-six Thousand Nine Hundred One
Dollars ($10,856,901) on account of this Mortgage. Any amounts that Buyer is
required to pay pursuant to this Agreement will be paid by Buyer in sufficient
time to permit the closing on the closing date in cash or by check or federal
wire transfer of immediately available U.S. funds to an account of Chicago Title
Insurance Company, Boston, Massachusetts (Sharon Sbordan, Closing Officer),
which will act as closing agent hereunder (the "Closing Agent"), and hold those
funds for payment to Seller on the closing. Buyer acknowledges that as of this
date, Lender has not consented to this sale.

     3.   Seller's Representations and Warranties. Seller represents and
warrants to Buyer that:

          (a) Seller is: (i) in good standing and validly existing as a Delaware
corporation, qualified to do business in the Commonwealth of Massachusetts, and
(ii) has the power and authority to do all things required of it by the terms of
this Agreement.

this Agreement and the consummation of the transaction herein contemplated in
accordance with the terms of this Agreement have been obtained.

on behalf of Seller.

          (d)  This Agreement and each and every document and instrument to be
executed and delivered by Seller pursuant to this Agreement, when fully executed

enforceable against Seller in accordance with their respective terms.

          (e)  It has not engaged any brokers, agents, finders or similar
parties in connection with this transaction who are due any commissions or
similar fees from Buyer.

          (f)  Seller is not a foreign person within the meaning of Section
1445(f)(3) of the Internal Revenue Code of 1986, as amended.

          (g)  Seller has not granted to anyone any right to occupy or lease the
Premises (except for Seller under the Lease).

          (h)  The Premises is being conveyed subject to the Mortgage, but
otherwise Seller is conveying the Premises (other than the Personal Property)
free and clear of any liens, security interests, licenses, leases or other
exceptions to title created by Seller or its affiliates (including, without
limitation, any mechanics liens).

          (i)  This purchase and sale is not a preference, and it will not
render Seller insolvent or unable to pay its debts as they become due (excluding
any debts or obligations to the extent arising from any failure of the Lender to
consent to this transaction), and the Purchase Price represents fair market
value for the Premises. The Premises, including the Personal Property, does not
represent all or substantially all of Seller's property. As of this date Seller
in its corporate capacity does not owe, and as of the closing will not owe, any
delinquent taxes to the Commonwealth of Massachusetts.

     4.   Buyer's Representations and Warranties. Buyer represents and warrants
to Seller that:

          (a)  Buyer is: (i) in good standing and validly existing as a
Massachusetts Limited Partnership, qualified to do business in the Commonwealth
of Massachusetts, and (ii) has the power and authority to do all things required
of it by the terms of this Agreement.

          (b)  All internal approvals of Buyer required for the execution of
this Agreement and the consummation of the transaction herein contemplated in
accordance with the terms of this Agreement have been obtained.

          (c)  [INTENTIONALLY OMITTED]

on behalf of Buyer. This purchase and sale is not a preference, and it will not
render Buyer insolvent or unable to pay its debts as they become due, and the
Purchase Price represents fair market value for the Premises.

          (e)  This Agreement and each and every document and instrument to be
executed and delivered by Buyer pursuant to this Agreement, when fully executed
and delivered, shall constitute the valid and binding obligations of Buyer,
enforceable against Buyer in accordance with their respective terms.

parties in connection with this transaction who are due any commissions or
similar fees from Seller.

     9.   "As Is;" Release.

          (a)  Except for the covenants, indemnities, representations and
warranties of Seller specifically set forth in this Agreement or in the Lease or
in any other agreements entered into by Seller that benefit Buyer (collectively,
the "Seller Liabilities"), Buyer acknowledges that Seller is selling, and Buyer
will accept, the Premises in its "AS IS" condition, with "ALL FAULTS" and
subject to the Mortgage and all other matters of record and exceptions to title,
as of the date of closing, without any warranty or representation by Seller, its
employees, directors, officers, agents, consultants, representatives, partners
or affiliates, subsequent buyers of the Premises, anyone acting on their behalf,
or their respective successors and assigns (including Seller, collectively,
"Seller's Affiliates"), whether relating to the Premises or this transaction or
otherwise. Buyer has had the opportunity to fully investigate the Premises, and
agrees that it is not relying on any information or documents received from or
made available by or on behalf of Seller's Affiliates. Furthermore, Buyer agrees
that except for the covenants, representations and warranties of Seller
specifically set forth in this Agreement or any other agreements entered into by
Seller that benefit Buyer, Seller's Affiliates have not made and Buyer is not
relying on any representation, warranty, inducement or statement (including,
without limitation, those regarding the accuracy or completeness of any
information or documents furnished, or the physical or environmental condition
of the Premises, or violations of laws, or other matters).

          (b)  As of the closing, Buyer and its employees, shareholders,
directors, officers, agents, consultants, representatives, partners, affiliates,
successors and assigns (including Buyer, collectively, "Buyer's Affiliates"),
for good and valuable consideration, irrevocably agree to release, discharge,
and waive as against Seller's Affiliates all of the following (collectively, the
"Released Liabilities"): all claims, liabilities, obligations, costs, losses,
damages, penalties, judgements, actions, and causes of action of any type
(including, without limitation, attorneys' fees and costs), direct or indirect,
known or unknown, foreseen or unforeseen, in connection with the Premises
(including, without limitation, the physical and environmental conditions
thereof), but specifically excluding from the Released Liabilities those arising
from or in connection with the Seller Liabilities or any breach thereof. Buyer's
Affiliates will not commence, aid in any way, or prosecute against any of
Seller's Affiliates any claim involving or based on any of the Released
Liabilities. The provisions in this Article 9 extend to Released Liabilities
which the releasing parties may not know or suspect to exist in their favor at
the time these provisions are agreed to or at a later date, which if known to
them would materially affect their willingness to agree. The provisions of this
Article 9 will survive the closing or termination of this Agreement.

     10.  Default. A party will be in default hereunder if it materially
breaches its obligations hereunder and fails to cure within two (2) business
days after written notice from the other party, or if any of its representations
or warranties in this Agreement are materially untrue or incorrect when made or
as of the closing. Seller will indemnify, defend and hold harmless Buyer's
Affiliates from all claims, liabilities, obligations, costs, losses, damages,
penalties, judgements, actions, and causes of action of any type (including,
without limitation, attorneys' fees and costs) in connection with Seller's
breach of Seller's Liabilities. Buyer will indemnify, defend and hold harmless
Seller's Affiliates from all claims, liabilities, obligations, costs, losses,
damages, penalties, judgements, actions, and causes of action of any type
(including, without limitation, attorneys' fees and costs) in connection with
Buyer's breach of its representations, warranties and indemnities in this
Agreement.

     12.  Miscellaneous Provisions.

          (a)  This Agreement is an integrated agreement and, except for the
agreements contemplated herein and any closing or escrow instructions to
accomplish this agreement (including the Undertakings Agreement), it contains
the entire understanding between the parties with respect to the transaction
contemplated herein, and all prior agreements, understandings, representations
and statements, oral or written are merged into this Agreement. No provision of
this Agreement may be waived except by an instrument signed by the party against
whom the enforcement of such waiver is sought. All modifications (including any
extensions) of this Agreement will be effective only if signed by Seller and
Buyer.

          (b)  This Agreement will be governed by, and construed in accordance
with, the local, internal laws of the Commonwealth of Massachusetts applicable
to agreements to be wholly performed therein, without regard to conflicts of
laws.

          (c)  This Agreement will be binding on and will inure to the benefit
of the parties hereto and their respective successors and assigns, provided,
however, that Buyer will not have the right or power to assign or transfer this
Agreement. This Agreement and its terms are for the sole benefit of the parties
hereto (including, without limitation, the released Buyer's Affiliates) and
their permitted successors and assigns, if any, and no other person or entity
will have any right of action hereon or right to claim any right or benefit from
this Agreement or its terms or be deemed a third party beneficiary hereunder.
Except for the representations and warranties specifically set forth in this
Agreement or in the Lease or made as part of Seller's Liabilities, there are no
representations and warranties, express or implied, that are being made or
relied on by the parties hereto. All representations, warranties, covenants and
indemnities hereunder will survive the closing of this Agreement.

          (d)  The section titles or captions in this Agreement are for
convenience only and will not be deemed to be part of this Agreement for
purposes of interpreting, construing or enforcing any of the provisions of this
Agreement. All pronouns and any variations of pronouns will be deemed to refer
to the masculine, feminine, or neuter, singular or plural, as the identity of
the parties may require. Whenever the terms referred to herein are singular, the
same will be deemed to mean the plural, as the context indicates, and vice
versa. This Agreement will not be construed as if it had been prepared only by
Buyer or Seller but rather as if both Buyer and Seller had prepared and
negotiated it. This Agreement is severable, and if any term, covenant,
condition, or provision of this Agreement or the application thereof to any
person or circumstance will, at any time or to any extent, be invalid or
unenforceable, the remainder of this Agreement, or the application of such term
or provision to persons or circumstances other than those to which it is held
invalid or unenforceable, will not be affected thereby, and each term or
provision of this Agreement will be valid and will be enforced to the fullest
extent permitted by law.

                                       4

<PAGE>

          (e)  If the time period by which any right, option or election
provided under this Agreement must be exercised, or by which any act required
hereunder must be performed, or by which the closing must be held, expires on a
day which is a Saturday, Sunday, or official federal or Commonwealth of
Massachusetts holiday, then such time period will be automatically extended
through the close of business on the next business day.

          (f)  The parties do not anticipate that there will be any sales,
transfer, excise or similar taxes or fees collectable by any governmental agency
in connection with the conveyance of the Personal Property to Buyer
(collectively, "Sales Tax"), because the Personal Property is being conveyed as
part of the Premises. Nonetheless, if Seller is required pursuant to written
notice from a governmental agency to pay any Sales Tax, it will promptly notify
Buyer and Buyer will cause the Sales Tax to be paid in full in a timely manner.
Buyer's obligations in this Section 12(ff) will survive the closing.

          (g)  No Seller's Affiliate (other than Seller itself) nor any Buyer's
Affiliate (other than Buyer itself) will have any personal liability hereunder,
nor will any of them be named personally in any suit, claim, action or
proceeding hereunder nor will any of their assets be attached, liened or levied
or in any other way become liable for any of the obligations of Seller or Buyer
hereunder (unless they otherwise agree in writing), nor will either party
attempt to "pierce the corporate veil" of any of Seller's Affiliates or any of
Buyer's Affiliates.

          (h)  This agreement may be executed in two (2) or more counterparts,
each of which will be deemed to be an original, but all of which taken together
will constitute one and the same Agreement. All of the Exhibits referenced in
this Agreement will be deemed incorporated into this Agreement.

          (i)  If there is any dispute relating to this Agreement or a breach
hereunder, the prevailing party will be entitled to payment for all costs and
attorneys' fees (both trial and appellate) incurred in connection therewith. All
suits, actions, claims and proceedings will be filed, commenced and prosecuted
solely in the state or federal courts in Boston, Massachusetts, which will have
sole and exclusive jurisdiction and venue. The provisions in this Subsection (i)
will survive the closing or termination of this Agreement.

          (j)  As a material part of the consideration to Buyer, within thirty
(30) days after the closing Seller will cause to be irrevocably released and
discharged from the Personal Property and any other real or personal property or
interests therein conveyed to Buyer hereunder, pursuant to UCC-3's and any other
necessary documents, at no cost or liability to Buyer, any and all liens,
security interests, licenses, leases or other exceptions to title created by the
Seller's Affiliates (including, without limitation, those created to secure any
debt of Seller or any interest in that debt in favor or now owned or hereafter
acquired by ClearBlue Technologies, Inc. or any of its affiliates), and Seller
will indemnify the Buyer Affiliates for and defend them and hold them free and
harmless from all claims, liabilities, obligations, costs, losses, damages,
penalties, judgements, actions, and causes of action of any type (including,
without limitation, attorneys' fees and costs), direct or indirect, known or
unknown, foreseen or unforeseen, arising from Seller's failure to perform these
obligations as and when required. Seller's obligations in this Subsection (j)
collectively are referred to as the "Lien Release Obligations" and will survive
the closing.

     In witness whereof, intending to be legally bound, the parties have
executed this Agreement under seal as of the date first set forth above.

NaviSite, Inc.
400 Minuteman Road
Andover, Massachusetts 01810

Re:  Project located at 400 Minuteman Road, Andover, Massachusetts (the
     "Project") Temporary License to Occupy Space on 2nd Floor

Gentlemen:

     Farm Associates Limited Partnership, as Landlord, and NaviSite, Inc., as
Tenant, have entered into a Lease, dated as of___________(the "New Lease"), for
space on the 1st floor of the Building. For convenience, unless otherwise
defined herein, terms used in this letter agreement have the same meanings as
those used in the New Lease. The New Lease is attached hereto as Exhibit "A."

     Pursuant to a previous lease of the entire Project, Tenant leased both the
1st and 2nd floors of the Building (the "Old Lease"). The Old Lease has expired
and terminated, and pursuant to the New Lease, Tenant has agreed to lease the
Premises, which includes only space located on the 1st floor of the Building and
a rooftop Penthouse, and Tenant has no right to lease or occupy space on the 2nd
floor of the Building. However, Tenant will be performing Tenant improvements to
its Premises under the New Lease to accommodate its personnel that it intends to
relocate from the 2nd floor to the 1/st/ floor, and so Tenant has requested the
right to temporarily occupy the 2nd floor space for a limited period of time so
that it can relocate its personnel to the 1st floor in an orderly fashion.
     To accommodate Tenant, but only subject to the terms hereof (including,
without limitation, the termination rights described herein), Landlord is
willing to permit Tenant to temporarily occupy the space on the 2nd floor of the
Building (the "Temporary Space"), which is agreed to contain 76,500 square feet
of rentable area.

     To accomplish this, for good and valuable consideration, the receipt and
sufficiency of which are acknowledged, Landlord and Tenant agree as follows:

     1.   Landlord hereby grants and Tenant accepts a revocable license
permitting Tenant to temporarily occupy the Temporary Space on the terms and
conditions of this letter agreement. This revocable license to temporarily
occupy the Temporary Space, as embodied in this letter agreement and subject to
the terms and conditions hereof, is called the "Temporary License."

NaviSite, Inc.

     2.   Although this is a revocable license, and not a lease, to avoid
needless redrafting, and subject to the terms and conditions of this Temporary
License, the terms and conditions of the New Lease are incorporated herein by
this reference and form a part of this Temporary License, except as follows:

          (1)  This Temporary License is an accommodation to Tenant, and so
Landlord is not required to pay for or perform any work in connection with the
Temporary Space, and Landlord will incur no Liabilities to Tenant (including,
without limitation, any Liabilities for negligence) in connection with this
Temporary License or the Temporary Space, all of which are hereby irrevocably
waived by Tenant on its own behalf and on behalf of its Affiliates and insurers
(although this will not affect Landlord's Liabilities to Tenant under the New
Lease).

          (2)  The term of the Temporary License begins on the date hereof and
ends on the earliest of: six (6) months from the date hereof; or written notice
of termination from Landlord or Tenant if the Temporary Space is damaged by
casualty so as to be rendered untenantable; or Tenant's default hereunder or
under the Lease not cured within applicable notice and cure periods; or on at
least ten (10) days' prior written notice from Tenant if it entirely vacates and
surrenders possession of the Temporary Space. Also, if Landlord leases or enters
into letters of intent to lease less than all or substantially all of the
Temporary Space, on at least thirty (30) days' prior written notice to Tenant
Landlord will have the right to reclaim those areas of the Temporary Space and
revoke this Temporary License with respect to those areas, and in that case
Tenant will cooperate with Landlord and make diligent efforts to vacate and
surrender those areas to Landlord as soon as reasonably possible, but in any
case on or before the required date in Landlord's written notice. Tenant has no
extension or renewal rights or options of any type under this Temporary License.

          (3)  The Premises under this Temporary License will be the Temporary
Space.

          (4)  Tenant will not be required to pay base rent or any share of
Taxes or Landlord's insurance costs for the Temporary Space or under this
Temporary License (except as specifically set forth in Section 2(g) hereof), but
during the term of this Temporary License it will pay in accordance with the New
Lease and in addition to all amounts payable under the New Lease: (i) the costs
for all utilities serving the Temporary Space plus 50% of all Operating Costs;
less (ii) the utility costs and the Operating Costs payable during that same
period by other tenants of the Temporary Space pursuant to their leases of the
Temporary Space (if any such leases are entered into by Landlord, and Landlord
has no obligation to enter into such leases).

          (5)  Tenant agrees, represents and warrants that it has not engaged or
dealt with any broker, agent, finder or similar party of any type in connection
with this Temporary License, and Tenant will defend, indemnify and hold Landlord
harmless from all Liabilities in connection with any claim by any broker, agent,
finder or similar party engaged by Tenant or with whom Tenant has dealt in
connection with this Temporary License.

          (6)  Neither Landlord nor Tenant will be required to repair, rebuild
or maintain the Temporary Space or the rest of the Project under this Temporary
License, except that Tenant will be responsible for repairs and maintenance
required as a result of any negligent or intentional misconduct by Tenant.
Tenant will not be permitted to make any Alterations to the Temporary Space
without Landlord's prior written approval. Tenant will not have the right or
power to sublease, assign or otherwise Transfer this Temporary License or the
Temporary Space or any interest therein under any circumstances or allow anyone
other than Tenant's employees to occupy the Temporary Space.

          (7)  Time is of the essence, and holding over will not be permitted
unless otherwise specifically agreed to in writing by Landlord in its sole and
arbitrary discretion. If Tenant holds over in the Temporary Space, then Tenant
will indemnify, defend and hold harmless Landlord and its Affiliates from all
Liabilities in connection therewith, and in addition to any other rights and
remedies and amounts payable hereunder, Tenant will pay additional fees for the
occupancy of the Temporary Space at the same rate as the base rent payable under
the New Lease.

     3.   (a) The sole right and remedy of Tenant and its Affiliates for any
default by, or Liabilities incurred as a result of the acts or omissions of,
Landlord or its Affiliates under or in connection with this Temporary License or
the Temporary Space will be to terminate or specifically enforce this Temporary
License, and all other rights and remedies are hereby irrevocably waived.
Nothing in this Temporary License will affect the rights, obligations and other
Liabilities of the parties under the New Lease, except that if Tenant fails to
vacate and surrender the Temporary Space as and when required hereunder, it will
also be deemed to be a default by Tenant under the New Lease, and Landlord may
exercise any or all of its rights hereunder and/or under the New Lease. A
default by Tenant under the New Lease pursuant to the terms of Article 21
thereof also will be a default by Tenant hereunder, and Landlord may exercise
any or all of its rights hereunder and/or under the New Lease, all of which are
cumulative and not exclusive.

          (b)  If Tenant defaults hereunder, Landlord will have the right, but
not the obligation, to enforce any or all of the rights and remedies set forth
in the New Lease in connection

with that default hereunder, even though this is a temporary license and not a
lease, in addition to the rights and remedies available to Landlord for a breach
of this temporary license, all of which are cumulative and not exclusive.

Technologies, Inc., this letter agreement will be a binding agreement executed
under seal.
