     Section 1.3   NON-ASSIGNMENT OF CERTAIN CUSTOMER CONTRACTS AND PERMITS.

             (a)   Notwithstanding anything to the contrary in this Agreement,
to the extent that the assignment hereunder of any Customer Contract, Assumed
Lease or Permit shall require the consent of any third party, neither this
Agreement nor any action taken pursuant to its provisions shall constitute an
assignment or an agreement to assign if such assignment or attempted assignment

PROVIDED that in each such case, Seller and Buyer shall each use commercially
reasonable efforts to obtain the consent of such other party to such assignment
to Buyer as soon as possible after the date of this Agreement.

             (b)   If, on or prior to 90 days following the Closing Date or such

or any advance billings made by Seller at the request of Buyer for periods after

Seller shall invoice the Customer Contracts for all advance billings in the
month of April 2001, both commercial in advance and residential in advance for
the quarter or the month, as applicable, and in accordance with Seller's past
practices. Seller and Seller Parent shall be entitled to collect all such
advance billings. At Closing Buyer and/or Buyer Parent shall reduce from the
purchase price paid at Closing all amounts to be so advanced billed. To the
extent such advance billing is only estimated at Closing, Buyer and Seller agree
to make such adjustments to the Retained Amount (defined below) as to properly
reflect the actual amount of such advance billing. All amounts deducted from the
purchase price for advance billings and prepaids or deposits for services
rendered during the Revenue Tracking Period, (defined below) shall be included
in the calculation of Target Revenue (defined below). Attached hereto as
Schedule 1.4 is a calculation of such advance billings, prepaids or deposits to
be deducted as of the Closing.

(as defined in Section 2.1 (a)) shall be allocated among the Assets for tax
purposes in accordance with SCHEDULE 1.5. Seller and Buyer will follow and use
such allocation in all tax returns, filings or other related reports made by
them to any governmental agencies. To the extent that disclosures of this
allocation are required to be made by the parties to the Internal Revenue
Service ("IRS") under the provisions of Section 1060 of the Internal Revenue
Code of 1986, as amended (the "Code"), or any regulations thereunder, each of
Buyer and Seller will disclose such reports to the other prior to filing with
the IRS.

the obligations to make any such payments, deliveries and other transfers may be
applied against each other and netted. In addition, each party hereunder
acknowledges that, and has entered into this Agreement in reliance on the fact

             (a)   At Closing Buyer shall retain the amount set forth on Annex I
(the "Retained Amount") from the Purchase Price for the Business. The Retained
Amount shall be subject to reduction and offset as set forth below. The Retained
Amount shall be paid thirty (30) days after the completion of the Revenue

calender months following Closing (the "Revenue Tracking Period"), Buyer shall
offset the Retained Amount by an amount equal to 12 times for each dollar that

amount, Seller shall pay over to Buyer the amount of such deficiency.

             (c)   In the event Buyer fails to perform the services under the
Customer Contracts or performs such services poorly, as documented by the
customer, Buyer shall not be permitted to off-set the Retained Amount by the
amount of lost revenues for such customer or make a Material Contract adjustment
under subsection 1.3(b) for such customers..

             (d)   During the Revenue Tracking Period, Buyer shall not change
the billing rates for the Business but may make service changes and shall only
make selective pricing deductions on a customer by customer basis at Buyer's
discretion and only if necessary to retain business.

                                   ARTICLE 3.

following receipt of Seller's notice or deemed notice electing not to cure in
which to (a) elect to waive its objection to any Unpermitted Exception which
Seller does not elect to cure, or (b) amend this Agreement to delete the parcel
of owned Land affected by Buyer's objections and to deduct the value of the

not later than ten days after execution of this Agreement, Seller shall deliver

on or prior to the Closing Date a statutory declaration in form and substance
satisfactory to Buyer and the Title Company or attorneys issuing title opinions,
declaring that no changes have been made to that part of the Land depicted in
such survey since the date of such survey or, alternatively, stating any changes
made to the Land depicted in such survey since the date of such survey. If no
survey is delivered by Seller to Buyer, Buyer may cause a survey to be prepared

the Title Company in connection with the issuance of the Title Policy or the
attorneys in connection with the issuance of title opinions shall be defined
herein as a "Survey."

including the Closing Date, the parties shall prorate and apportion, on a per
diem basis, as of the close of business on the Closing Date, the real and
personal property taxes and assessments, both general and special, for the
Assets, based upon the last available tax statement. If the actual real and
personal property taxes paid by any party in respect of the period of the
proration exceed the amount so pro rated, the other party shall, upon
presentation of appropriate paid tax bills, reimburse the first party for such
excess. In addition, Seller shall be charged the cost of discharging any and all
financial encumbrances, including, but not limited to, all deeds of trusts,
mortgages and mechanics and materialmen's liens on the Land, unless any of the
foregoing is a Permitted Exception or Permitted Encumbrance. With respect to
Leased Land, the parties shall prorate, as of the close of business on the
Closing Date, to the extent relevant rent, real estate taxes, operating costs
and any other amounts due under the applicable Real Estate Lease. If the pro
rata amounts are not known as of the Closing Date, adjustments shall be made
post Closing at such time as they are known to the parties. Notwithstanding
anything to the contrary contained in this Agreement, Buyer shall pay any
federal, state or local sales, use, excise, transfer, conveyance taxes or
registration costs or similar taxes, or fees (including any mortgage tax or
other similar governmental charges) arising in connection with the transactions
contemplated by this Agreement.

     Section 3.8   POST CLOSING TITLE AND SURVEY WORK. Notwithstanding anything
herein to the contrary, if as of the Closing Date (a) through no fault of Buyer,

under this Agreement, PROVIDED Seller agrees in writing at the Closing to
provide such missing items promptly after the Closing; or (ii) delay the Closing
with respect to such parcel of Land only and close with respect to such Land
when the missing items are obtained, with (A) Buyer and Seller to execute an

of payment of the Retained Amount; (B) the representations and covenants of
Seller with respect to the applicable Land continuing until the extended closing

after the Closing Date in furnishing to Buyer information, evidence, testimony,
and other assistance in connection with obtaining all necessary permits and

preparation of tax returns and all other legitimate tax matters relating to the
Assets or Business. Such cooperation shall include (without limitation) making

conduct of the business of the other party or its affiliated entities. Without
the prior written consent of Seller, which consent shall not be unreasonably
withheld or delayed, Buyer shall not file (or cause to be filed) any returns in
respect of the Assets or Business relating to taxes with respect to any period

under all laws, regulations, ordinances and orders of public authorities to

Seller's and Seller Parent's Certificate of Incorporation (certified by the

part of Seller and Seller Parent are necessary to authorize the execution and
delivery of this Agreement or the consummation by Seller and Seller Parent of

(collectively, the "Rights"), none of which Rights, to the best of Seller's and
Seller Parent's knowledge, infringe on the rights of others and all of which are
now valid, in good standing and in full force and effect except for where such
infringement or the failure to be valid, in good standing and full force and
effect would not have a Material Adverse Effect, and except that no
representation is made as to the effect of the transactions contemplated under
this Agreement on any Permit, some of which may not be transferable or may

thereof. Seller and Seller Parent agree that to the extent Buyer does not employ

such Covenants upon written notice from Buyer or Buyer Parent or Seller or
Seller Parent discovering a violation of such Covenants. It is the intention of
the parties hereto that Buyer and Buyer Parent obtain the full benefit of such
Covenants. If under applicable law Buyer or Buyer Parent is able to enforce such
Covenants, Buyer and Buyer Parent shall do so at Buyer or Buyer's Parent
expense. In such circumstance Seller or Seller Parent shall be deemed to have
assigned to Buyer and Buyer Parent such claim. Seller and Seller Parent shall

action against such covenantor and assign such to Buyer and Buyer Parent within
30 days of Buyer or Buyer's Parent request, then Seller and Seller Parent hereby
authorizes and empowers Buyer or Buyer Parent to make, constitute and appoint
any officer or agent of Buyer or Buyer Parent, as Buyer or Buyer Parent may
select in their exclusive discretion, as Seller and Seller Parent's true and
lawful attorney-in-fact, with the power to bring such action in Seller and
Seller Parent's name but at Buyer and Buyer's Parent expense and to use Seller
or Seller name on all documents, papers, filings, causes of action, injunction
actions or other legal process necessary for Buyer or Buyer Parent to enforce
the Covenants. Seller and Seller Parent hereby ratify all that such attorney
shall lawfully do or cause to be done by virtue hereof other than acts or
omissions which are grossly negligent or constitute willful misconduct. This
power of attorney, being coupled with an interest, shall be irrevocable for the
term of the Covenants.

years after the Closing Date: provided, however, that the representations and
warranties in Sections 5.12 shall last indefinitely and the representations and
warranties in Sections 5.4(d) and 5.9 shall survive until 30 days after the

     Section 11.2  INDEMNIFICATION BY SELLER PARENT AND SELLER. Seller and
Seller Parent agree that they will each, jointly and severally, indemnify,
defend, protect and hold harmless Buyer, its officers, shareholders, directors,
divisions, subdivisions, affiliates, subsidiaries, parent, agents, employees,
successors and assigns at all times from and after the date of this Agreement
from and against all liabilities, claims, damages, actions, suits, proceedings,
demands, assessments, adjustments, penalties, losses, costs and expenses
whatsoever (including specifically, but without limitation, court costs,
reasonable attorneys' and expert witness fees and expenses and expenses of
investigation) whether equitable or legal, matured or contingent, known or
unknown, foreseen or unforeseen, ordinary or extraordinary, patent or latent,
whether arising out of occurrences prior to, at or after the date of this
Agreement, incurred as a result of or incident to: (a) any breach of,
misrepresentation in, untruth in or inaccuracy in the representations and
warranties by Seller or Seller Parent set forth herein, or in the Schedules,
Exhibits or certificates attached hereto or delivered pursuant hereto by Seller
or Seller Parent; (b) breach of any agreement or covenant on the part of Seller
Parent or Seller made in this Agreement; (c) any liability, claim or other cost
or obligation retained pursuant to Article 10; or (d) any claim by a third party
that, if true, would mean that a condition for indemnification set forth in
subsections (a) through (c) of this Section 11.2 had been satisfied.

     Section 11.3  INDEMNIFICATION BY BUYER AND BUYER PARENT. Buyer and Buyer
Parent, jointly and severally, agree that they will indemnify, defend, protect
and hold harmless Seller and Seller Parent at all times from and after the
Closing Date from and against all liabilities, claims, damages, actions, suits,
proceedings, demands, assessments, adjustments, penalties, losses, costs and
expenses whatsoever (including specifically, but without limitation, court
costs, reasonable attorneys' fees and expenses and expenses of investigation)
whether equitable or legal, matured or contingent, known or unknown, foreseen or
unforeseen, ordinary or extraordinary, patent or latent, incurred by Seller or
Seller Parent as a result of or incident to: (a) any breach of misrepresentation
in, untruth in or inaccuracy in the representations and warranties of Buyer or
Buyer Parent set forth herein, or in the Schedules, Exhibits or certificates
attached hereto or delivered pursuant hereto by Buyer or Buyer Parent; (b)
breach of any agreement or covenant on the part of Buyer or Buyer Parent made in
this Agreement; (c) any liability, claim or other cost or obligation assumed
pursuant to Section 10.2; or (d) any claim by a third party that, if true, would
mean that a condition for indemnification set forth in subsections (a) through
(c) of this Section 11.3 had been satisfied.

     Section 11.4  LIMITATION ON LIABILITY. The indemnification obligations set
forth in this Article 11 shall apply only if a Closing occurs, and then only
after the aggregate amount of indemnification obligations of the Indemnifying
Party (as defined in Section 11.5) under this Agreement exceed $25,000 at which
time the indemnification obligations shall be effective as to all amounts. The
foregoing indemnification threshold shall not apply to any indemnification
obligations on account of (a) taxes, (b) a breach of the covenants set forth in
Section 10.1 or 10.2, except to the extent the Indemnified Party (as defined in
Section 11.5) knew of such breach

<Page>

CONFIDENTIAL                                                        PENNSYLVANIA

on or prior to the Closing, (c) a title or survey matter resolved under Section
3.8. or (d) a breach of the representations in Section 2.2 or any adjustment to
the Purchase Price as set forth herein. Further, the indemnification obligations
set forth in this Article 11 and each Article 11 under the Related Agreements
shall be limited to an aggregate amount not to exceed all the Purchase Prices in
each Related Agreement actually paid by Buyer, Buyer Parent and its Affiliates
as adjusted in accordance with Article 2; PROVIDED that the foregoing cap shall
not apply to indemnification obligations on account of taxes. The indemnified
party shall not have the right to indemnification hereunder to the extent that
an adjustment to the Purchase Price or other monetary adjustment has already
been made under this Agreement.

     Section 11.5  INDEMNIFICATION PROCEDURE BETWEEN BUYER AND SELLER. Upon the
occurrence of any claim for which indemnification is believed to be due
hereunder, the party seeking indemnification (the "Indemnified Party") shall
provide notice of such claim to the party from whom indemnification is sought
(the "Indemnifying Party"), stating in general terms the circumstances giving
rise to the claim, specifying the amount of the claim (or an estimate thereof)
and making a request for any payment then believed due (subject to the
limitations herein). Upon receipt of any such notice, both the Indemnified Party
and the Indemnifying Party shall use all reasonable efforts to cooperate and
arrive at a mutually acceptable resolution of such dispute within the next 30
days. If it is finally determined that all or a portion of such claim amount is
owed to the Indemnified Party, the Indemnifying Party shall (subject to the
terms of Section 11.4) within 10 days of such determination, pay the Indemnified
Party such amount owed in cash, together with interest from the date that the
Indemnified Party initially requested such payment until the date of actual
payment, at an annual rate equal to the prime interest rate then generally in
effect on the date of payment as set forth in THE WALL STREET JOURNAL.

     Section 11.6  PROCEDURE FOR INDEMNIFICATION WITH RESPECT TO THIRD PARTY
CLAIMS.

             (a)   If any third party shall notify an Indemnified Party with
respect to any matter (a "Third Party Claim") that may give rise to a claim for
indemnification against an Indemnifying Party or if any party who may make a
claim for indemnification under this Agreement otherwise becomes aware of any
matter that may give rise to such a claim or wishes to make such a claim
(whether or not related to a Third Party Claim), then the Indemnified Party
shall promptly notify each Indemnifying Party thereof in writing; PROVIDED that
no delay on the part of the Indemnified Party in notifying any Indemnifying
Party shall relieve the Indemnifying Party from any obligation hereunder unless
(and then solely to the extent) the Indemnifying Party is thereby prejudiced.

             (b)   Any Indemnifying Party will have the right to assume the
defense of any claim or any litigation resulting therefrom, PROVIDED that (i)
the counsel for the Indemnifying Party who shall conduct the defense of such
claim or litigation shall be reasonably satisfactory to the Indemnified Party,
(ii) the Indemnified Party may participate in such defense at such Indemnified
Party's expense, and (iii) the omission by any Indemnified Party to give notice
as provided herein shall not relieve the Indemnifying Party of its
indemnification obligation under this Agreement except to the extent that such
omission results in a failure of actual notice to the Indemnifying Party and
such Indemnifying Party is materially damaged as a result of such failure to
give notice. Except with the prior written consent of the Indemnified Party, no
Indemnifying

Party, in the defense of any such claim or litigation, shall consent to entry of
any judgment or order, interim or otherwise, or enter into any settlement that
provides for injunctive or other nonmonetary relief affecting the Indemnified
Party or that does not include as an unconditional term thereof the giving by
each claimant or plaintiff to such Indemnified Party of a release from all
liability with respect to such claim or litigation. In the event that the
Indemnified Party shall in good faith determine that the conduct of the defense
of any claim subject to indemnification hereunder or any proposed settlement of
any such claim by the Indemnifying Party might be expected to affect adversely
the Indemnified Party, or that the Indemnified Party may have available to it
one or more defenses or counterclaims that are inconsistent with one or more of
those that may be available to the Indemnifying Party in respect of such claim
or any litigation relating thereto, the Indemnified Party shall have the right
at all times to take over and assume control over the defense, settlement,
negotiations or litigation relating to any such claim at the sole cost of the
Indemnifying Party, provided that if the Indemnified Party does so take over and
assume control, the Indemnified Party shall not settle such claim or litigation
without the written consent of the Indemnifying Party, such consent not to be
unreasonably withheld. In the event that the Indemnifying Party does not assume
the defense of any matter as above provided, the Indemnified Party shall have
the full right to defend against any such claim or demand and shall be entitled
to settle or agree to pay in full such claim or demand. In any event, the
Indemnifying Party and the Indemnified Party shall cooperate in the defense of
any claim or litigation subject to this Article 11 and the records of each shall
be available to the other with respect to such defense.

             (c)   TAX TREATMENT OF PAYMENT. Unless otherwise required by law,
Seller and Buyer agree to treat any payment made under this Agreement
(including, without limitation, Sections 2.2 and Article 11) as an adjustment to
the Purchase Price.

                                   ARTICLE 12.

                            TERMINATION OF AGREEMENT

     Section 12.1  TERMINATION BY BUYER. Buyer, by notice in the manner

Affiliates), unless such date shall be extended by the mutual written consent of
Seller and Buyer.

     Section 12.4  EFFECT OF TERMINATION. Termination of this Agreement pursuant

                                   ARTICLE 13.

                         NONDISCLOSURE: NONSOLICITATION

     Section 13.1  NONDISCLOSURE BY SELLER AND SELLER PARENT. Seller and Seller
Parent recognize and acknowledge that they had in the past, currently have, and
in the future may possibly have, access to certain confidential information of
Buyer, such as lists of customers, operational policies, and pricing and cost
policies that are valuable, special and unique assets of Buyer and its
businesses. Seller and Seller Parent each agree that they will not, except as
may be required by law or valid legal process, disclose such confidential
information to any person, firm, corporation, association or other entity for
any purpose or reason whatsoever, except to authorized representatives of Buyer,
unless such information becomes known to the public generally through no fault
of Seller or Seller Parent. In the event of a breach or threatened breach by
Seller or Seller Parent of the provisions of this Section, Buyer shall be
entitled to an injunction restraining such party from disclosing, in whole or in
part, such confidential information. Nothing herein shall be construed as
prohibiting Buyer from pursuing any other available remedy for such breach or
threatened breach, including, without limitation. the recovery of damages. The
provisions of this Section shall apply at all times prior to the Closing Date
and for a period of three years following the first to occur of (i the Closing
Date and (ii) termination of this Agreement without a Closing having occurred.

     Section 13.2  NONDISCLOSURE BY BUYER AND BUYER PARENT. Buyer and Buyer
Parent recognize and acknowledge that they have in the past, currently have, and
prior to the Closing Date, will have access to certain confidential information
of Seller and Seller Parent, such as lists of customers, operational policies,
and pricing and cost policies that are valuable, special and unique assets of
Seller. Buyer and Buyer Parent agree that they will not, except as may be
required by law or valid legal process, disclose such confidential information
to any person, firm, corporation, association, or other entity for any purpose
or reason whatsoever, prior to the Closing Date except to authorized
representatives of Seller, unless such information becomes known to the public
generally through no fault of Buyer. In the event of a breach or threatened
breach by Buyer or Buyer Parent of the provisions of this Section, Seller shall
be entitled to an injunction restraining such party from disclosing, in whole or
in part, such confidential information. Nothing contained herein shall be
construed as prohibiting Seller from pursuing any other available remedy for
such breach or threatened breach, including, without limitation, the recovery of
damages. The provisions of this Section shall apply at all times prior to the
Closing Date and for a period of three years following the first to occur of (i)
the Closing Date and (ii) termination of this Agreement without a Closing having
occurred.

     Section 13.3  NON-SOLICITATION BY SELLER. Seller and Seller Parent agree
that for a period of three years following the Closing Date, they will not, and
will cause their Affiliates (as defined in Section 5.15(b)) not to, solicit or
accept business from any existing customer accounts of the Business; PROVIDED
that Seller and Seller Parent shall be permitted to service any national account
within such markets if pursuant to the terms of the relevant national account
agreement Seller and Seller Parent are unable to subcontract the services to
Buyer.

     Section 13.4  CONFIDENTIAL INFORMATION. Neither Seller Parent nor Seller
(nor any of their subsidiaries or affiliated entities) shall at any time
subsequent to the Closing, except as explicitly requested by Buyer, use for any
purpose, disclose to any person, or keep or make copies of any records and files
containing, any confidential information relating exclusively to the Business,
the Assets, or the liabilities assumed by Buyer hereunder, all such `information
being deemed to be transferred to Buyer hereunder. For purposes hereof,
"confidential information" shall mean information relating exclusively to the
Business, the Assets, or the liabilities assumed by Buyer hereunder, including,
without limitation, all customer and vendor lists and related information, all
information concerning the Business' processes, products, costs, prices, sales,
marketing and distribution methods, properties and assets, liabilities,
finances, employees, all privileged communications and work product, and any
other information not previously disclosed to the public directly by Seller
Parent or Seller. The foregoing provisions shall not apply to any information
which is or relates to an Excluded Asset or which is or relates to the
liabilities retained by Seller hereunder. If at any time after the Closing,
Seller Parent or Seller should discover that they are in possession of any
records and files containing the confidential information of Buyer, then the
party making such discovery shall immediately turn such records and files over
to Buyer, which shall upon request make available to the surrendering party any
information contained therein which is not confidential information. Seller
Parent and Seller severally agree that they will not assert a waiver of loss of
confidential or privileged status of the information based upon such possession
or discovery.

     Section 13.5  EQUITABLE RELIEF FOR VIOLATIONS. The parties expressly
covenant and agree that if any of them violates, or overtly threatens to
violate, the covenants set forth in this Article 13 (the "Restrictive
Covenants"), the non-violating party shall be entitled to an accounting and
repayment of all profits, compensation, commissions. remuneration, or benefits
which the violating party. directly or indirectly, realized and/or may realize
as the result of, arising out of, or in connection with any such violation or
threatened violation. The parties acknowledge further that an irreparable injury
may result to the non-violating party and its business in the event of a breach
by the violating party of the Restrictive Covenants. The parties also
acknowledge and agree that the damages or injuries which a non-violating party
sustains as a result of a breach by a violating party of the Restrictive
Covenants are difficult to ascertain and money damages alone may not be an
adequate remedy to a non-violating party. The parties therefore expressly agree
that if a controversy arises concerning the rights or obligations of a party
under the Restrictive Covenants, such rights or obligations shall be enforceable
by an arbitral decree of specific performance and a non-violating party shall
also be entitled to any injunctive relief from the arbitral tribunal pursuant to
Section 14.12 necessary to prevent or restrain any violation of the Restrictive
Covenants. Such relief however, shall be cumulative and non-exclusive and shall
be in addition to any other remedy to which the parties may be entitled.

obligations hereunder) and the Seller and Seller Parent may assign this
Agreement and their rights hereunder to Bank of America, N.A., as U.S.
Collateral Agent (in such capacity, the "U.S. Collateral Agent") pursuant to the
Restated U.S. Security Agreement dated as of November 26, 1999 among CERI, L.P.,
various other subsidiaries of Seller Parent and the U.S. Collateral Agent." This
Agreement shall be binding upon and shall inure to the benefit of the parties
hereto, and the successors and permitted assigns of Buyer, Buyer Parent, Seller
and Seller Parent. This Agreement, upon execution and delivery, constitutes a
valid and binding agreement of the parties hereto enforceable in accordance with

                (a)     Notwithstanding anything to the contrary in this
Agreement, to the extent that the assignment hereunder of any Customer Contract,
Assumed Lease or Permit shall require the consent of any third party, neither
this Agreement nor any action taken pursuant to its provisions shall constitute
an assignment or an agreement to assign if such assignment or attempted
assignment would constitute a breach thereof or result in the loss or diminution
thereof; PROVIDED that in each such case, Seller and Buyer shall each use
commercially reasonable efforts to obtain the consent of such other party to
such assignment to Buyer as soon as possible after the date of this Agreement.

                (b)     If, on or prior to 90 days following the Closing Date or

revenue generated from such Material Contract that is not assigned (the
"Material Contract Purchase Price Adjustment"). For purpose of this Section,
"Material Contract" means a Customer Contract that is a contract with a

Business. Seller shall be entitled to all such sums allocable to services
performed on or before the close of business on the business day preceding the

to be performed thereafter and shall be solely liable for the performance
thereof. Any advance billings made prior to the Closing date relating to

or any advance billings made by Seller at the request of Buyer for periods after
the Closing date shall be deducted from the purchase price paid at Closing.
Seller shall invoice the Customer Contracts for all advance billings in the
month of April 2001, both commercial in advance and residential in advance for
the quarter or the month, as applicable, and in accordance with Seller's past
practices. Seller and Seller Parent shall be entitled to collect all such
advance billings. At Closing Buyer and/or Buyer Parent shall reduce from the
purchase price paid at Closing all amounts to be so advanced billed. To the
extent such advance billing is only estimated at Closing, Buyer and Seller agree
to make such adjustments to the Retained Amount (defined below) as to properly
reflect the actual amount of such advance billing. All amounts deducted from the
purchase price for advance billings and prepaids or deposits for services
rendered during the Revenue Tracking Period, (defined below) shall be included
in the calculation of Target Revenue (defined below). Attached hereto as
Schedule 1.4 is a calculation of such advance billings, prepaids or deposits

tax purposes in accordance with SCHEDULE 1.5. Seller and Buyer will follow and
use such allocation in all tax returns, filings or other related reports made by
them to any governmental agencies. To the extent that disclosures of this
allocation are required to be made by the parties to the Internal Revenue
Service ("IRS") under the provisions of Section 1060 of the Internal Revenue
Code of 1986, as amended (the "Code"), or any regulations thereunder, each of
Buyer and Seller will disclose such reports to the other prior to filing with
the IRS.

acknowledge that, and have entered into this Agreement in reliance on the fact
that, all transactions under this Agreement and the Related Agreements
constitute a single business and contractual relationship and have been entered

payments, deliveries and other transfers made by each party in respect of any
Related Agreement shall be deemed to have been made in consideration of
payments, deliveries and other transfers in respect of the other Related
Agreements and the obligations to make any such payments, deliveries and other

hereunder acknowledges that, and has entered into this Agreement in reliance on

Annex I (the "Retained Amount") from the Purchase Price for the Business. The
Retained Amount shall be subject to reduction and offset as set forth below. The
Retained Amount shall be paid thirty (30) days after the completion of the
Revenue Tracking Period (defined below). The revenues or invoices pursuant to
the Customer Contracts listed on SCHEDULE 2.2 shall not be counted towards the
Target Revenue (defined below).

                (b)     If the average monthly gross revenues billed by Buyer
for the Business for services rendered by Buyer after Closing from the Customer
Contracts of Seller set forth on SCHEDULE 1.1(h) do not average the amount set
forth on Annex I for the Business (the "Target Revenue") for three (3) full
calender months following Closing (the "Revenue Tracking Period"), Buyer shall
offset the Retained Amount by an amount equal to 12 times for each dollar that
the actual amounts invoiced by Buyer is less than the Target Revenue set forth
herein. In the event that the Retained Amount is insufficient to pay such
amount, Seller shall pay over to Buyer the amount of such deficiency.

                (c)     In the event Buyer fails to perform the services under
the Customer Contracts or performs such services poorly, as documented by the
customer, Buyer shall not be permitted to off-set the Retained Amount by the
amount of lost revenues for such customer or make a Material Contract adjustment
under subsection 1.3(b) for such customers.

                (d)     During the Revenue Tracking Period, Buyer shall not
change the billing rates for the Business but may make service changes and shall
only make selective pricing deductions on a customer by customer basis at
Buyer's discretion and only if necessary to retain business.

                                there are no proceedings or amendments pending
                                and brought by, or threatened by, any third

                                Parent's possession. To the best of the
                                respective knowledge of each, Seller Parent or
                                Seller is not in default under any Real Estate

        Section 11.3    INDEMNIFICATION BY BUYER AND BUYER PARENT. Buyer and
Buyer Parent, jointly and severally, agree that they will indemnify, defend,
protect and hold harmless Seller and Seller Parent at all times from and after
the Closing Date from and against all liabilities, claims, damages, actions,
suits, proceedings, demands, assessments, adjustments, penalties, losses, costs
and expenses whatsoever (including specifically, but without limitation, court
costs, reasonable attorneys' fees and expenses and expenses of investigation)
whether equitable or legal, matured or contingent, known or unknown, foreseen or
unforeseen, ordinary or extraordinary, patent or latent, incurred by Seller or
Seller Parent as a result of or incident to: (a) any breach of misrepresentation
in, untruth in or inaccuracy in the representations and warranties of Buyer or
Buyer Parent set forth herein, or in the Schedules, Exhibits or certificates
attached hereto or delivered pursuant hereto by Buyer or Buyer Parent; (b)
breach of any agreement or covenant on the part of Buyer or Buyer Parent made in
this Agreement; (c) any liability, claim or other cost or obligation assumed
pursuant to Section 10.2; or (d) any claim by a third party that, if true, would
mean that a condition for indemnification set forth in subsections (a) through
(c) of this Section 11.3 had been satisfied.

        Section 11.4    LIMITATION ON LIABILITY. The indemnification obligations
set forth in this Article 11 shall apply only if a Closing occurs, and then only
after the aggregate amount of indemnification obligations of the Indemnifying
Party (as defined in Section 11.5) under this

Agreement exceed $50,000 at which time the indemnification obligations shall be
effective as to all amounts. The foregoing indemnification threshold shall not
apply to any indemnification obligations on account of (a) taxes, (b) a breach
of the covenants set forth in Section 10.1 or 10.2, except to the extent the
Indemnified Party (as defined in Section 11.5) knew of such breach on or prior
to the Closing, (c) a title or survey matter resolved under Section 3.8. or (d)
a breach of the representations in Section 2.2 or any adjustment to the Purchase
Price as set forth herein. Further, the indemnification obligations set forth in
this Article 11 and each Article 11 under the Related Agreements shall be
limited to an aggregate amount not to exceed all the Purchase Prices in each
Related Agreement actually paid by Buyer, Buyer Parent and its Affiliates as
adjusted in accordance with Article 2; PROVIDED that the foregoing cap shall not
apply to indemnification obligations on account of taxes. The indemnified party
shall not have the right to indemnification hereunder to the extent that an
adjustment to the Purchase Price or other monetary adjustment has already been
made under this Agreement.

        Section 11.5    INDEMNIFICATION PROCEDURE BETWEEN BUYER AND SELLER. Upon
the occurrence of any claim for which indemnification is believed to be due
hereunder, the party seeking indemnification (the "Indemnified Party") shall
provide notice of such claim to the party from whom indemnification is sought
(the "Indemnifying Party"), stating in general terms the circumstances giving
rise to the claim, specifying the amount of the claim (or an estimate thereof)
and making a request for any payment then believed due (subject to the
limitations herein). Upon receipt of any such notice, both the Indemnified Party
and the Indemnifying Party shall use all reasonable efforts to cooperate and
arrive at a mutually acceptable resolution of such dispute within the next 30
days. If it is finally determined that all or a portion of such claim amount is
owed to the Indemnified Party, the Indemnifying Party shall (subject to the
terms of Section 11.4) within 10 days of such determination, pay the Indemnified
Party such amount owed in cash, together with interest from the date that the
Indemnified Party initially requested such payment until the date of actual
payment, at an annual rate equal to the prime interest rate then generally in
effect on the date of payment as set forth in THE WALL STREET JOURNAL.

        Section 11.6    PROCEDURE FOR INDEMNIFICATION WITH RESPECT TO THIRD
PARTY CLAIMS.

                (a)     If any third party shall notify an Indemnified Party
with respect to any matter (a "Third Party Claim") that may give rise to a claim
for indemnification against an Indemnifying Party or if any party who may make a
claim for indemnification under this Agreement otherwise becomes aware of any
matter that may give rise to such a claim or wishes to make such a claim
(whether or not related to a Third Party Claim), then the Indemnified Party
shall promptly notify each Indemnifying Party thereof in writing; PROVIDED that
no delay on the part of the Indemnified Party in notifying any Indemnifying
Party shall relieve the Indemnifying Party from any obligation hereunder unless
(and then solely to the extent) the Indemnifying Party is thereby prejudiced.

                (b)     Any Indemnifying Party will have the right to assume the
defense of any claim or any litigation resulting therefrom, PROVIDED that (i)
the counsel for the Indemnifying Party who shall conduct the defense of such
claim or litigation shall be reasonably satisfactory to the Indemnified Party,
(ii) the Indemnified Party may participate in such defense at such Indemnified
Party's expense, and (iii) the omission by any Indemnified Party to give notice
as

<Page>

CONFIDENTIAL                                                       ROCHESTER, NY

provided herein shall not relieve the Indemnifying Party of its indemnification
obligation under this Agreement except to the extent that such omission results
in a failure of actual notice to the Indemnifying Party and such Indemnifying
Party is materially damaged as a result of such failure to give notice. Except
with the prior written consent of the Indemnified Party, no Indemnifying Party,
in the defense of any such claim or litigation, shall consent to entry of any
judgment or order, interim or otherwise, or enter into any settlement that
provides for injunctive or other nonmonetary relief affecting the Indemnified
Party or that does not include as an unconditional term thereof the giving by
each claimant or plaintiff to such Indemnified Party of a release from all
liability with respect to such claim or litigation. In the event that the
Indemnified Party shall in good faith determine that the conduct of the defense
of any claim subject to indemnification hereunder or any proposed settlement of
any such claim by the Indemnifying Party might be expected to affect adversely
the Indemnified Party, or that the Indemnified Party may have available to it
one or more defenses or counterclaims that are inconsistent with one or more of
those that may be available to the Indemnifying Party in respect of such claim
or any litigation relating thereto, the Indemnified Party shall have the right
at all times to take over and assume control over the defense, settlement,
negotiations or litigation relating to any such claim at the sole cost of the
Indemnifying Party, provided that if the Indemnified Party does so take over and
assume control, the Indemnified Party shall not settle such claim or litigation
without the written consent of the Indemnifying Party, such consent not to be
unreasonably withheld. In the event that the Indemnifying Party does not assume
the defense of any matter as above provided, the Indemnified Party shall have
the full right to defend against any such claim or demand and shall be entitled
to settle or agree to pay in full such claim or demand. In any event, the
Indemnifying Party and the Indemnified Party shall cooperate in the defense of
any claim or litigation subject to this Article 11 and the records of each shall
be available to the other with respect to such defense.

                (c)     TAX TREATMENT OF PAYMENT. Unless otherwise required by
law, Seller and Buyer agree to treat any payment made under this Agreement
(including, without limitation, Sections 2.2 and Article 11) as an adjustment to
the Purchase Price.

been cured, after written notice thereof, on or before the Closing Date.

        Section 12.2    TERMINATION BY SELLER. Seller may, by notice in the
manner hereinafter provided on or before the Closing Date, terminate this
Agreement the event of a material breach by Buyer or Buyer Parent in the

agreements or conditions contained herein on its part to be performed, and such
breach shall not have been cured, after written notice thereof, on or before the
Closing Date.

        Section 12.3    TERMINATION DATE. This Agreement may be terminated by
either Seller or Buyer by written notice to the other party if the transactions
contemplated hereby shall not have been consummated pursuant hereto by 5:00 p.m.
(MST) on April 30, 2001 (other than as a result of a breach of this Agreement by

extended by the mutual written consent of Seller and Buyer.

        Section 12.4    EFFECT OF TERMINATION. Termination of this Agreement
pursuant to this Article 12 shall not in any way terminate, limit or restrict
the rights and remedies of any party hereto against any other party which has
breached this Agreement prior to the termination hereof.

                         NONDISCLOSURE: NONSOLICITATION

        Section 13.1    NONDISCLOSURE BY SELLER AND SELLER PARENT. Seller and
Seller Parent recognize and acknowledge that they had in the past, currently
have, and in the future may possibly have, access to certain confidential
information of Buyer, such as lists of customers, operational policies, and
pricing and cost policies that are valuable, special and unique assets of Buyer
and its businesses. Seller and Seller Parent each agree that they will not,
except as may be required by law or valid legal process, disclose such
confidential information to any person, firm, corporation, association or other
entity for any purpose or reason whatsoever, except to authorized
representatives of Buyer, unless such information becomes known to the public
generally through no fault of Seller or Seller Parent. In the event of a breach
or threatened breach by Seller or Seller Parent of the provisions of this
Section, Buyer shall be entitled to an injunction restraining such party from
disclosing, in whole or in part, such confidential information. Nothing herein
shall be construed as prohibiting Buyer from pursuing any other available remedy
for such breach or threatened breach, including, without limitation. the
recovery of damages. The provisions of this Section shall apply at all times
prior to the Closing Date and for a period of three years following the first to
occur of (i the Closing Date and (ii) termination of this Agreement without a
Closing having occurred.

        Section 13.2    NONDISCLOSURE BY BUYER AND BUYER PARENT. Buyer and Buyer
Parent recognize and acknowledge that they have in the past, currently have, and
prior to the Closing Date, will have access to certain confidential information
of Seller and Seller Parent, such as lists of customers, operational policies,
and pricing and cost policies that are valuable, special and unique assets of
Seller. Buyer and Buyer Parent agree that they will not, except as may be
required by law or valid legal process, disclose such confidential information
to any person, firm, corporation, association, or other entity for any purpose
or reason whatsoever, prior to the Closing Date except to authorized
representatives of Seller, unless such information becomes known to the public
generally through no fault of Buyer. In the event of a breach or threatened
breach by Buyer or Buyer Parent of the provisions of this Section, Seller shall
be entitled to an injunction restraining such party from disclosing, in whole or
in part, such confidential information. Nothing contained herein shall be
construed as prohibiting Seller from pursuing

CONFIDENTIAL                                                       ROCHESTER, NY

any other available remedy for such breach or threatened breach, including,
without limitation, the recovery of damages. The provisions of this Section
shall apply at all times prior to the Closing Date and for a period of three
years following the first to occur of (i) the Closing Date and (ii) termination
of this Agreement without a Closing having occurred.

        Section 13.3    NON-SOLICITATION BY SELLER. Seller and Seller Parent
agree that for a period of three years following the Closing Date, they will
not, and will cause their Affiliates (as defined in Section 5.15(b)) not to,
solicit or accept business from any existing customer accounts of the Business;
PROVIDED that Seller and Seller Parent shall be permitted to service any
national account within such markets if pursuant to the terms of the relevant
national account agreement Seller and Seller Parent are unable to subcontract
the services to Buyer.

        Section 13.4    CONFIDENTIAL INFORMATION. Neither Seller Parent nor
Seller (nor any of their subsidiaries or affiliated entities) shall at any time
subsequent to the Closing, except as explicitly requested by Buyer, use for any
purpose, disclose to any person, or keep or make copies of any records and files
containing, any confidential information relating exclusively to the Business,
the Assets, or the liabilities assumed by Buyer hereunder, all such `information
being deemed to be transferred to Buyer hereunder. For purposes hereof,
"confidential information" shall mean information relating exclusively to the
Business, the Assets, or the liabilities assumed by Buyer hereunder, including,
without limitation, all customer and vendor lists and related information, all
information concerning the Business' processes, products, costs, prices, sales,
marketing and distribution methods, properties and assets, liabilities,
finances, employees, all privileged communications and work product, and any
other information not previously disclosed to the public directly by Seller
Parent or Seller. The foregoing provisions shall not apply to any information
which is or relates to an Excluded Asset or which is or relates to the
liabilities retained by Seller hereunder. If at any time after the Closing,
Seller Parent or Seller should discover that they are in possession of any
records and files containing the confidential information of Buyer, then the
party making such discovery shall immediately turn such records and files over
to Buyer, which shall upon request make available to the surrendering party any
information contained therein which is not confidential information. Seller
Parent and Seller severally agree that they will not assert a waiver of loss of
confidential or privileged status of the information based upon such possession
or discovery.

        Section 13.5    EQUITABLE RELIEF FOR VIOLATIONS. The parties expressly
covenant and agree that if any of them violates, or overtly threatens to
violate, the covenants set forth in this Article 13 (the "Restrictive
Covenants"), the non-violating party shall be entitled to an accounting and
repayment of all profits, compensation, commissions. remuneration, or benefits
which the violating party. directly or indirectly, realized and/or may realize
as the result of, arising out of, or in connection with any such violation or
threatened violation. The parties acknowledge further that an irreparable injury
may result to the non-violating party and its business in the event of a breach
by the violating party of the Restrictive Covenants. The parties also
acknowledge and agree that the damages or injuries which a non-violating party
sustains as a result of a breach by a violating party of the Restrictive
Covenants are difficult to ascertain and money damages alone may not be an
adequate remedy to a non-violating party. The parties therefore expressly agree
that if a controversy arises concerning the rights or obligations of a party
under the Restrictive Covenants, such rights or obligations shall be enforceable
by an

arbitral decree of specific performance and a non-violating party shall
also be entitled to any injunctive relief from the arbitral tribunal pursuant to
Section 14.12 necessary to prevent or restrain any violation of the Restrictive
Covenants. Such relief however, shall be cumulative and non-exclusive and shall
be in addition to any other remedy to which the parties may be entitled.

of the other parties from all claims for such commission or fee and from all
attorneys' fees, litigation costs and other expenses relating to such claim.

        Section 14.5    EXPENSES OF TRANSACTION. Except as otherwise provided in
