                               PURCHASE AGREEMENT

AGREEMENT dated as of May 2, 2000 by and between Paramount Operations Inc.
(Formerly known as Paramount Financial Corporation and Paramount Computer
Leasing Corporation), a Delaware corporation having its principal office and
place of business at One Jericho Plaza, Jericho, New York 11753 ("Seller"), and
Stamford Computer Group Inc., a Connecticut corporation having its principal
office and place of business at 74 West Park Place, Stamford, CT 06901
("Buyer").

                                   WITNESSETH:

That in consideration of the mutual undertakings herein contained, the parties
agree as follows:

         1. SALE. Seller agrees to sell and Buyer agrees to purchase from Seller
the equipment (the "Equipment") listed on Schedule A attached hereto (the
"Schedule") and incorporated herein by reference. The term "Equipment" as used
in this Agreement shall not include the "Inapplicable Items" (as defined below),
and notwithstanding anything to the contrary contained in this Agreement, Seller
is not transferring any interest in the Inapplicable Items.

         2. PURCHASE PRICE. The purchase price of the Equipment shall be the sum
of (i) and (ii) referred to in the next sentence. Buyer shall pay such purchase
price (i) by a cash payment to Seller in the amount of $700,114.00 and (ii) by
Buyer assuming Seller's obligations with respect to, and Buyer taking title to
the Equipment subject to, the liens (the "Liens") held by the lenders
("Lenders") as described on the Schedule (the "Liens"), which Liens secure
outstanding debt in the aggregate outstanding principal amount of $______(as of
the dates set forth on the Schedule). The cash payment to be made to Seller in
(i) above shall be paid on or before May __, 2000 by wire transfer to Seller (in
accordance with wire transfer instructions to be given to Buyer) of a cash
payment in the amount of $700,114.00. The date such wire transfer is made is
sometimes called the "Closing Date".

         3. DELIVERY. Buyer shall accept delivery of the Equipment at the
locations specified in the Leases (as hereinafter defined).

         4. TITLE. Title to the Equipment will be free and clear of all liens,
leases, claims and encumbrances of any kind except for the Liens and the rights
of the lessees ("Lessees") under the leases described on the Schedule (the
"Leases"). Simultaneously with the receipt by Seller of such wire transfer, (i)
Seller shall deliver to Buyer a bill of sale for the Equipment (the "Bill of
Sale"), in the form annexed hereto as Exhibit A, transferring title thereto to
Buyer free and clear of all liens, leases, claims and encumbrances of any kind
other than the Liens and the rights of the Lessees under the Leases and (ii)
Buyer and Seller will enter into an Assignment and Assumption Agreement (the
"Assignment Agreement"), in the form annexed hereto as Exhibit B, pursuant to
which all rights of Seller as lessor under the Leases will be assigned to Buyer,
free and clear of all liens, claims and encumbrances other than the Liens and
the rights of the Lessees under the Leases. Additionally, simultaneously with
the receipt by Seller of such wire transfer, Seller shall deliver to Buyer (i)
notices, in the form of Exhibits C-1 and C-2 hereto, addressed to the Lessees
under the Funded Leases (as hereinafter defined) and signed by Seller (ii)
notices, in the form of Exhibit D hereto, addressed to the Lessees under the
Unfunded Leases (as hereinafter defined) and signed by the Seller and (iii)
notices, in the form of Exhibit E hereto, addressed to the Lenders under the
Funded Leases and signed by Seller. Additionally, simultaneously with the
receipt by Seller of such wire transfer, (i) Buyer and Seller shall enter into a
letter agreement, in the form of Exhibit F hereto, pursuant to which Buyer shall
agree to lend possession to Seller of


<PAGE>

the original master leases referred to in such letter and (ii) Buyer and Seller
shall enter into a letter agreement, in the form of Exhibit G hereto, pursuant
to which Seller shall agree to lend possession to Buyer of the original master
lease with Cendant Operations Inc. Title to the Equipment and the Leases will
not transfer prior to receipt by Seller of such wire transfer in the amount of
$700,114.00. The term "Unfunded Leases" means any Leases designated on the
Schedule as "Unfunded Leases". The term "Funded Leases" means any Leases which
are not Unfunded Leases.

         5. SUBORDINATION. Buyer hereby agrees that its interest in the
Equipment and the Leases will be subject and subordinate in all respects to the
Liens and the rights of the Lessees under the Leases. Effective upon delivery of
the Bill of Sale, Seller hereby assigns to Buyer, and Buyer hereby assumes and
agrees to perform, all obligations of Seller under the Liens and the debts
secured thereby and all documents or instruments related thereto. Without
limiting the generality of the foregoing, Buyer hereby agrees (effective upon
the passage of title) not to take any action or omit to take any action which
would cause a default or breach (i) under any of the Leases or (ii) under any
documents related to any of the Liens or any of the debts secured thereby.
Without limiting the generality of the foregoing, in the event that either party
receives any payment under a Funded Lease which belongs to a Lender, such party
will immediately forward such payment to such Lender. Seller and Buyer each
hereby agrees to exert commercially reasonable efforts (i) to promptly obtain
the consents of the Lenders to the transactions described herein and (ii) to
promptly obtain the releases by the Lenders of the Seller from any of Seller's
obligations related to the Liens (or any debts secured thereby), including
(without limitation) to promptly execute and deliver to the Lenders any
documents or instruments reasonably required by any of the Lenders in connection
therewith. Seller and Buyer shall equally bear and promptly pay to the Lenders
any reasonable fees charged by the Lenders in connection with obtaining such
consents. Additionally, Seller and Buyer each hereby agrees to exert
commercially reasonable efforts to obtain acknowledgements from the Lessees of
the transactions described herein (in substantially the form annexed hereto as
Exhibits C-1, C-2 and D), including (without limitation) to promptly execute and
deliver to the Lessees any documents or instruments reasonably requested by any
of the Lessees.

         6. REPRESENTATIONS AND WARRANTIES.

         6.1 REPRESENTATIONS AND WARRANTIES OF SELLER. Seller represents and
warrants to, and covenants and agrees with, Buyer as follows:

delivered, are in full force and effect, constitute the valid and binding
obligations of the Seller, as lessor, and the Lessees, as lessees, thereunder,
are enforceable against Seller and the Lessees in accordance with their
respective terms (subject to laws of general application affecting creditor's
rights and to general principles of equity, and except that no representation or
warranty is made with respect to the enforceability (1) of any automatic
extension or renewal provisions or (2) of any interest or late payment
provisions ) and to the best of the Seller's knowledge, no Event of Default
exists thereunder by the Lessees, (ii) the Equipment is located at the places
designated in the Leases (to the best of the Seller's knowledge) and the
Equipment has been accepted under the Leases; and (iii) no Event of Default
exists under the Liens. Seller has not received any "termination letters" with
respect to the Leases except as set forth on the Schedule.

         (b) Seller owns the Equipment and the Leases free and clear of any and
all leases, liens, claims and encumbrances other than the Liens and the rights
of the Lessees under the Leases. By the delivery of the Bill of Sale to Buyer
and upon the execution and delivery of the Assignment



                                       2
<PAGE>

Agreement, Seller will convey to Buyer title to the Equipment and the Leases
free and clear of any and all leases, liens, claims and encumbrances other than
the Liens and the rights of the Lessees under the Leases.

         (c) Seller is a corporation duly and validly organized and existing in
good standing under the laws of the State of Delaware and has full power and
authority to own its properties and carry on its business in the places where
such properties are located and such business is conducted.

         (d) Seller has the power and authority to enter into, execute and
deliver this Agreement, the Bill of Sale, the Assignment Agreement and all other
instruments and documents executed and delivered and/or received, or to be

herein referred to and to carry out the sale and transfer of the Equipment and
the Leases to Buyer and the transactions contemplated hereunder and thereunder.
(This Agreement, the Bill of Sale, the Assignment Agreement and all such other
instruments and documents are hereinafter referred to collectively as the
"Documents"). There is no action, suit or proceeding pending against Seller
before or by any court, administrative agency or other governmental authority
which brings into question the validity of, or might in any way impair, the
execution, delivery or performance by Seller of any Document. No approval of, or
consent from, any governmental authority is required for the execution,
delivery, or performance by Seller of any Document.

         (e) The execution and delivery of the Documents by Seller and the
performance by it of its obligations thereunder, including, without limitation,
the conveyance of the Equipment and the Lease and the acceptance of the purchase
price in exchange therefor, have been duly authorized by all necessary corporate
and/or other action of Seller and do not contravene, violate or conflict with
(i) any provision of Seller's articles of incorporation, by-laws or other
organizational documents or (ii) any law or any order, writ, injunction, decree,
rule or regulation of any court, administrative agency or any other governmental
authority (applicable to Seller or its assets).

         (f) Except as set forth in the Schedule or in the Documents, the
execution and delivery of the Documents by Seller, and the performance by Seller
of its obligations thereunder, do not conflict and are not inconsistent with,
and will not result (with or without the giving notice or passage of time or
both) in a breach of or constitute a default or require any consent under or
result in the creation of any lien, charge or encumbrance upon the Equipment or
the Lease pursuant to the terms of any credit agreement, indenture, mortgage,
purchase agreement, deed of trust, security agreement, lease, guarantee or other
instrument or agreement to which Seller is a party or by which Seller may be
bound or to which it may be subject (except that it is necessary to obtain the
consents of the Lenders with respect to the Funded Leases and the Equipment
covered thereby). Without limiting the foregoing and except as set forth on the
Schedule, Seller is not subject to any restriction or agreement which, with or
without the giving of notice, the passage of time or both, prohibits or would be
violated by, the execution, delivery and consummation of the Documents and the
transactions referred to therein (except that it is necessary to obtain the
consents of the Lenders with respect to the Funded Leases and the Equipment
covered thereby).

         (g) The Documents constitute, or when executed and delivered will
constitute, the legal, valid and binding obligations of Seller enforceable
against Seller in accordance with their respective terms, subject, however, to
laws of general application affecting creditors' rights and to general
principles of equity.

         (h) All sales, use, property, value added or other taxes, licenses,
tolls, inspection or other fees, bonds, permits or certificates which were or
may be required to be paid or obtained in

connection with the acquisition of the Equipment by Seller or the leasing (prior
to the Closing Date) of the Equipment to the Lessee have been, or when due will
promptly be, paid in full or obtained.

         (i) With respect to the Funded Leases, (1) Seller has delivered to
Buyer true and correct photocopies of the relevant master leases, (2) Seller
will deliver to Buyer on the Closing Date the originals of the relevant master
leases except for the master lease with Cendant Operations Inc. (and Seller will
deliver to Buyer on the Closing Date a true and correct certified photocopy of
the master lease with Cendant Operations Inc.) and (3) Seller will deliver to
Buyer, within 10 business days after the Closing Date, true and correct
photocopies of relevant equipment schedules, acceptance certificates, loan and
security agreements, promissory notes and each and every other material document
delivered to or by Seller in connection with the purchase of the relevant
Equipment or the leasing of the relevant Equipment or creating or relating to
the Liens (and to the extent that Seller may be in possession of originally
executed copies of relevant equipment schedules, Seller shall deliver same to
Buyer in lieu of photocopies). With respect to the Unfunded Leases, (1) Seller

master leases, and true and correct photocopies of relevant equipment schedules,
acceptance certificates and each and every other material document delivered in

documents (not including the original master lease with Cendant Operations Inc.
or ancillary documents related thereto) referred to in clause (1) of this
sentence (except that with respect to these Unfunded Leases designated on the

originals which are presently in Seller's files). To the best of Seller's

the extent assignable) the benefits of all warranties, representations,
covenants, and indemnities made to Seller by, or which Seller is entitled to
enforce against, any predecessor in title to the Equipment or the manufacturers

         (l) Effective upon the Closing Date and continuing for a period of one
year from the Closing Date, Seller agrees not to enter into any new leases (for
any equipment) with any of the Lessees (including, without limitation, any
upgrades to the Equipment) except that (1) Seller may extend or renew any
presently existing leases (not sold under this Agreement) between Seller and any
of the Lessees and (2) Seller may lease to Cendant Operations Inc. any upgrade
equipment (either as an attachment or as a replacement) to any of the equipment
leased under Equipment Schedule Nos. 5 and 13 with Cendant Operations Inc.

         (m) EXCEPT AS SPECIFICALLY SET FORTH IN THIS SECTION 6.1, THE
ASSIGNMENT AGREEMENT OR IN THE BILL OF SALE, SELLER MAKES NO WARRANTIES OR
REPRESENTATIONS OF ANY KIND OR NATURE, EXPRESS OR IMPLIED, CONCERNING THE
TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT, OR THE LIENS OR THE LEASES OR THE

PATENT INFRINGEMENT OR THE LIKE. SELLER SHALL, IN NO EVENT, BE LIABLE TO BUYER
FOR ANY INDIRECT, SPECIAL OR CONSEQUENTIAL DAMAGES CAUSED, DIRECTLY OR
INDIRECTLY, BY THE EQUIPMENT OR ANY INADEQUACY THEREOF FOR ANY PURPOSE, OR ANY
DEFICIENCY OR DEFECT THEREIN, OR THE USE OR MAINTENANCE THEREOF, OR ANY REPAIRS,
SERVICING OR ADJUSTMENTS THERETO.

6.2 REPRESENTATIONS AND WARRANTIES OF THE BUYER. The Buyer represents and
warrants to, and covenants and agrees with, the Seller as follows:

(a) Buyer is a corporation duly and validly organized and existing in good
standing under the laws of the State of Connecticut and has full power and
authority to own its properties and carry on its business where such properties
are located and such business is conducted.

(b) Buyer has the power and authority to enter into, execute and deliver the
Documents and to carry out the transactions contemplated thereunder.

(c) The execution and delivery of the Documents by Buyer, and the performance of
its obligations thereunder, have been duly authorized by all necessary corporate
and/or other action of Buyer and do not contravene, violate or conflict with (i)
any provision of Buyer's certificate of incorporation, by-laws or other
organizational documents, or (ii) any law or any order, writ, injunction,
decree, rule or regulation of any court, administrative agency or any other
governmental authority (applicable to Buyer or its assets). There is no action,
suit or proceeding pending against Buyer before or by any court, administrative
agency of other governmental authority which brings into question the validity
of, or might in any way impair, the execution, delivery or performance by Buyer
of any Document. No approval of, or consent from, any governmental authority is
required for the execution, delivery or performance by Buyer of any Document.

(d) The execution and delivery of the Documents by Buyer, and the performance by
Buyer of its obligations thereunder, do not conflict with and are not
inconsistent with, and will not result (with or without the giving of notice or
passage of time or both) in a breach of or constitute a default or require any
consent under or result in the creation of any lien, charge or encumbrance upon
the Equipment or the Leases pursuant to the terms of any credit agreement,
indenture, mortgage, purchase agreement, deed of trust, security agreement,
lease, guarantee or other instrument or agreement to which Buyer is a party or
by which Buyer may be bound or to which it may be subject. Without limiting the
foregoing, Buyer is not subject to any restriction or agreement which, with or
without the giving of notice, the passage of time or both, prohibits or would be
violated by, the execution, delivery and consummation of the Documents and the
transactions referred to therein.

(e) The Documents constitute, or when executed and delivered will constitute,
the legal, valid and binding obligations of Buyer enforceable in accordance with
their respective terms, subject, however, to laws of general application
affecting creditors' rights and to general principles of equity.

7. INDEMNIFICATION. Each of Seller and Buyer will indemnify the other and
protect, defend and hold it harmless from and against any and all loss, cost,
damage, injury or expense, including, without limitation, reasonable attorneys'
fees and court costs, wheresoever and howsoever arising, which the indemnified
party or its subsidiaries or stockholders, or any of its, or their,



                                       5
<PAGE>

directors, officers, agents, employees, stockholders, or partners, may incur by
reason of any breach or untruthfulness by the indemnifying party of any of its
representations, covenants, agreements, warranties or obligations set forth in
any of the Documents.

8. TAXES. Buyer shall pay or cause to be paid, as the case may be, when due, all
sales, franchise, use, property or other taxes (other than taxes based on the
net income of Seller), licenses, tolls, inspection or other fees, bonds, permits
or certificates now or hereafter imposed by or required to be paid or obtained
to or from any jurisdiction in connection with the sale of the Equipment by
Seller to Buyer.

9. SPECIAL INDEMNITY. Notwithstanding anything to the contrary contained in this
Agreement or any Document, Seller's maximum aggregate liability under this
Section 9 shall not exceed $160,000 in the aggregate (the "Maximum Aggregate
Liability Amount"), subject to reduction as hereinafter set forth. It is
acknowledged that the parties will be closing the transactions contemplated
hereunder without obtaining (i) the prior acknowledgements of the Lessees (the
"Lessee Acknowledgements") to the transfer of the Leases and the Equipment and
(ii) the prior consents or acknowledgements (as applicable) of the Lenders to
the transfer of the Equipment and the Leases (such consents or acknowledgements,
as applicable, are collectively called the "Lender Consents"). In order to
induce Buyer to close the contemplated transactions without obtaining, prior to
the Closing Date, the Lessee Acknowledgements and the Lender Consents, Seller
has agreed to make this indemnity in this Section 9. Subject to the Maximum
Aggregate Liability Amount, Seller agrees to indemnify Buyer for any losses
which Buyer may suffer as a result of not obtaining, prior to the Closing Date,
(i) with respect to the Applicable Funded Leases (as hereinafter defined), the
Lessee Acknowledgements related thereto or the Lender Consents related thereto
and (ii) with respect to the Unfunded Leases, the Lessee Acknowledgments related
thereto. With respect to any Applicable Funded Lease, if Buyer shall receive the
Lessee Acknowledgement related thereto and the Lender Consent related thereto,
the Maximum Liability Aggregate Amount shall be reduced by the "Reduction
Amount" set forth on the Schedule opposite such Applicable Funded Lease. Such
reduction may occur from time to time as such Lessee Acknowledgments and Lender
Consents are obtained. With respect to any Unfunded Lease, if Buyer shall
receive the Lessee Acknowledgement related thereto, the Maximum Aggregate
Liability Amount shall also be reduced by the "Reduction Amount" set forth on
the Schedule opposite such Unfunded Lease. Such reduction may occur from time to
time as such Lessee Acknowledgements are obtained. The term "Applicable Funded
Lease" means any Funded Lease which does not give the Lessee thereunder the
option or the right to purchase the related Equipment for $1.00 (or less) at the
expiration of the lease term thereof. The Seller's obligations under this
Section are conditioned upon Buyer exercising commercially reasonable efforts to
promptly obtain the Lessee Acknowledgments and the Lender Consents, including
(without limitation) executing such documents or instruments as any Lessee or
Lender may reasonably request in connection therewith, and Buyer and Seller
agree to exert such efforts (and execute such documents and instruments).
Without limiting the foregoing, Seller agrees to contact the Lessees and the
Lenders by telephone if the Lessee acknowledgements and the Lender
Acknowledgements are not obtained within 2 weeks from the Closing Date.

10. MISCELLANEOUS.

10.1 SURVIVAL. The covenants, agreements, indemnities, representations and
warranties made herein shall survive the execution and delivery of the Documents
and the consummation of the transactions described therein.



                                       6

foregoing, neither party may assign its rights or obligations under any of the
Documents without the consent of the other party.

performed therein without giving effect to the principles of conflict of laws
thereof.

10.5 CAPTIONS. Captions used herein are inserted for reference purposes only and
shall not affect the interpretation or construction of this Agreement.

10.6 COUNTERPARTS. This Agreement may be executed in one or more counterparts,
each of which shall be deemed an original, but all of which together shall
constitute one and the same agreement.

10.7 AMENDMENTS. This Agreement may be amended or varied only by a document, in
writing, of even or subsequent date hereof, executed by Buyer and Seller.

10.8 NO BROKERAGE FEES. No third party brokerage fees are payable in connection
with the transaction set forth herein.

10.9 FURTHER ASSURANCES. Each party hereto shall promptly execute and deliver
all such further instruments and documents, and promptly take such further
action, as may reasonably be requested by the other party in order to fully
carry out the intent and accomplish the purposes of the Documents and the
transactions referred to therein including, without limitation, any document or
instrument requested by any Lessee or Lender.

10.10 CANCELLATION. If the Closing Date shall not have occurred by May __, 2000,
this Agreement and any other Documents shall thereupon be automatically
cancelled without further liability (except that the defaulting or breaching
party shall be liable to the other party for damages).
