                             PURCHASE AND CONVEYANCE OF
                               SETTLEMENT RECEIVABLE

                   Section 2.1 SALE. (a) Upon the terms and subject to the
conditions set forth herein, the Seller hereby irrevocably sells, assigns,
transfers and conveys (collectively, "Transfers") to the Buyer, without
recourse (Except to the extent expressly provided herein), and the Buyer
hereby irrevocably purchases from the Seller, on the terms and subject to the
conditions specifically set forth herein, all rights, title, and interest of

Date, and all proceeds thereof (collectively, the "Settlement Receivable
Assets").  The execution by the Seller of this Agreement shall evidence the
Seller having relinquished all right, title and interest in and to and
control over the Settlement Receivable Assets; provided, however, the
foregoing sale, assignment, transfer and conveyance does not constitute an
assumption by the Buyer of any obligations of the Seller, or of any other
Person, to the obligor or to any other Person in connection with the
Settlement Receivable or under any other agreements or instruments relating
to the Settlement Receivable.

         (b)  In connection with the Transfer effected pursuant to this

         (c)  It is the express intent of the Seller and the Buyer that the
purchase of the Settlement Receivable Assets hereunder shall constitute a
sale of "accounts", and/or of "general intangibles" as each such term is used
in Article 9 of the UCC, which sale is absolute and irrevocable and which
provides the Buyer with the full benefits of ownership of the Settlement
Receivable Assets.  It is, further, not the intention of the Seller and the
Buyer that such conveyance be deemed a grant of a security interest in the
Settlement Receivable Assets by the Seller to the Buyer to secure a debt or
other obligation of the Seller.  However, in the event that, notwithstanding
the intent of the parties, the Settlement Receivable Assets are held by a
court of law to continue to be property of the Seller, then (i) this
Agreement also shall be deemed to be and hereby is a security agreement
within the meaning of the UCC; and (ii) the conveyance by the Seller provided
for in this Agreement shall be deemed to be and the Seller hereby grants to
the Buyer a security interest in and to all of the Seller's right, title and
interest in and to the Settlement Receivable Assets, all monies due or to
become due with respect thereto on and after the Closing Date and all
proceeds of such Settlement Receivable Assets to secure (1) the rights of the
Buyer under this Agreement and (2) a loan to the Seller in the original
principal amount, together with any interest thereon, of the Purchase Price
as set forth in this Agreement.  The Seller and the Buyer shall, to the
extent consistent with this Agreement, take such actions as may be necessary
to ensure that, if this Agreement were deemed to create a security interest
in the Settlement Receivable Assets, such security would be deemed to be a
perfected security interest of first priority in favor of the Buyer under
applicable law and will be maintained as such (subject only to any assignment
by the Buyer to MSFC as contemplated herein and in the Settlement Receivable
Purchase Agreement) throughout the term of this Agreement.

         (d)  Notwithstanding any other provisions hereof or of the
Settlement Receivable Purchase Agreement, the parties hereto hereby agree
that this Agreement is in addition to and in furtherance of the transactions
contemplated by the Settlement Receivable Purchase Agreement.

take such action in advance) necessary or advisable in the opinion of the 
Buyer to amend such financing statement or continuation statement so that it 
is not misleading.  The Seller shall neither change its chief executive 
office nor change the location of its principal records concerning the

necessary or advisable to cause the interest of the Buyer in the Settlement 
Receivable Assets and the Collections to continue to be perfected with the 
priority required by this Agreement. The Seller will at all times maintain

the Collections and other rights covered by this Agreement, as the Buyer may
request and reasonably require including executing and delivering to the
Buyer any instruments, financing or continuation statements or other writings
reasonably necessary or desirable to maintain the perfection or priority of
the ownership interest of the Buyer in the Settlement Receivable Assets and
the Collections under the UCC or other applicable law.  The Seller shall
provide the Buyer with copies of all monthly reports delivered to the
Commonwealth by the Seller relating to the Settlement Agreement and all
correspondence between the Commonwealth and the Seller relating to the
Settlement Receivable Assets.  At any time at the request of the Buyer, the
Seller shall deliver and sign any bills, statements or letters or other
writings necessary to carry out the terms and provisions of this Agreement
and to facilitate the collection of the Settlement Receivable Assets for the
benefit of the Buyer.

         (h)  Sale.  The Seller agrees to treat this conveyance for all
purposes (including, without limitation, tax and financial accounting
purposes) as a sale on all relevant books, records, tax returns, financial
statements and other applicable documents.

         (i)  Filings.  The Seller shall record and file, at its expense, on
or prior to the Closing Date any financing 

                                      13

statement wit resect to the Settlement Receivable meeting the requirement of 
applicable state law in such manner and in such jurisdictions as are 
necessary under the applicable UCC to perfect the sale of the Settlement 
Receivable from the Seller to the Buyer, and shall deliver a file-stamped 
copy of such financing statements or other evidence of such filings (which 
may, for purposes of this paragraph, consist of telephone confirmations of 
such filings) to the Buyer.

purchaser of the Settlement Receivable, inquires, the Seller will promptly
indicate that the Settlement Receivable has been sold to the Buyer and
interests in the Settlement Receivable have been sold by the Buyer to MSCC,
and the Seller will not claim any ownership interest in the Settlement
Receivable. 

         (k)  Payment Instructions.  The Seller will instruct the
Commonwealth to remit payments of the Settlement Receivable and interest
thereon to account #2037341 at PNC Bank National Association, Pittsburgh, PA,
TDCA #2037341, ABA #0430-0009-6, Attn: F.J. Deramo, which shall be an account
segregated from other assets and proceeds of the Seller.  Seller will in no
event provide alternate instructions to the Commonwealth that are
inconsistent with the foregoing, nor will Seller withdraw or revoke such
instructions without the prior written consent of the Liquidity Agent.

         (l)  Bankruptcy.  The Seller will not institute any bankruptcy
proceedings against the Buyer before the expiration of one year and one day
after MSFC's Notes (as defined in the Liquidity Loan Agreement) shall have
been paid in full.

         (m)  Amendments.  The Seller shall not make any amendments to (i)
its partnership agreement, (ii) any of the terms of, or waive any performance
under, this Agreement or (iii) any of the terms of the Settlement Agreement
which would affect the payment of the Settlement Receivable without the prior
written consent of MSCC, MSFC and the Liquidity Agent, which will not be
unreasonably withheld.

(directly or indirectly) by Envirotest Systems Corp. or any Affiliate
thereof.

         (o)  Information.  All Information, exhibits, financial statements,

         Section 6.1 MANDATORY REPURCHASE.  On and after the Closing Date,
in the event that any of the representations and warranties of the Seller
with respect to the Settlement Receivable Assets set forth in Section 4.1 and
4.2(b) and (c) shall not have been true and correct as of the date such
representation or warranty is made (which date shall be the Closing Date with
respect to Section 4.1), then, with respect to Section 4.1, no later than 180
days, and with respect to Section 4.2(b) and 4.2(c) no later than 90 days,
after receipt by the Seller of written notice of such breach given by the
Buyer, the Seller shall repurchase and accept a retransfer of such Settlement
Receivable Assets on the terms and conditions set forth below;
provided,however, that no such repurchase or retransfer shall be required to
be made with respect to the Settlement Receivable Assets if, on any day
within such 180 or 90 day period, as applicable, the representations and
warranties in Section 4.1, Section 4.2(b) and 4.2(c) that triggered such 180
or 90 day period shall then be true and correct in all material respects.  In
the event that any of the representations and warranties set forth in Section
4.2 (other than Section 4.2(b) or Section 4.2(c)) shall not have been true
and correct as of the date made, then (i) as of the date of a payment default
by the Commonwealth with respect to the Settlement Receivable Assets or (ii)
if on and after the date of such payment default the Seller is diligently
pursuing its legal rights to cure such payment default and has a reasonable
basis to believe it will prevail in its efforts to cure said payment default
(and no non-appealable order has determined to the contrary) 90 days after a
payment default by the Commonwealth with respect to the Settlement Receivable
Assets,the Seller shall repurchase and accept a retransfer o the Settlement
Receivable Assets on the terms and conditions set forth below;
provided,however, that no such repurchase or retransfer shall be required to
be made with respect to the Settlement Receivable Assets if prior to such
payment default or such 90 day period (if applicable) the representation or
the warranty which triggered this provision shall then be true and correct in
all material respects.  In consideration of such resale the Seller shall, on
the date of the resale of such Settlement Receivable Assets, pay to the Buyer
an amount equal to the sum of the unpaid principal balance of such Settlement
Receivable Assets on the date of repurchase and accrued and unpaid interest
thereupon accruing after the date hereof, any broken funding costs and any
swap breakage costs of the Buyer relating to interest rate hedging agreements
effected in connection with the transactions contemplated by this Agreement. 
In addition, in consideration of such resale, the Seller shall on each Note
Liability Date pay an amount equal to 

                                      15

<PAGE>

recourse, representation or warranty, all right, title and interest of the 
Buyer, in, to and under such Settlement Receivable Assets and all monies due 
or to become due with respect thereto and all proceeds of such Settlement 
Receivable Assets.  The obligation of the Seller to repurchase and accept 
resale of such Settlement Receivable Assets shall constitute the sole remedy 
respecting any breach of the representations and warranties set forth in 
Sections 4.1 and 4.2 with respect to the Settlement Receivable Assets.

         Section 6.2 CONVEYANCE OF REASSIGNED SETTLEMENT RECEIVABLE ASSETS.

Seller instruments of sale and assignment in such form as shall reasonably be
requested by the Seller, MSCC, MSFC or the Administrator, in order to vest in
the Seller, or its designee or assignee, all right, title interest of the
Buyer in, to and under such Settlement Receivable Assets, provided, that any
such reconveyance shall expressly state that it is made by the Buyer without
any recourse, representation or warranty.  Subject to the foregoing, the
Buyer shall execute such other documents or instruments of conveyance or take
such other actions as the Seller, MSCC, MSFC or the Administrator may
reasonably require to effect any repurchase of the Settlement Receivable
Assets pursuant to Section 6.1.
