                             CONDITIONS OF PURCHASES

                  SECTION  2.01.  Commitment.  (a) On the terms  and  conditions
hereinafter  set  forth,  the Banks  shall,  ratably  in  accordance  with their
respective Bank Commitments,  purchase Receivable Interests from the Seller from
time  to  time  during  the  period  from  the  date  hereof  to the  Commitment

outstanding  Capital  of  Receivable  Interests,  together  with  the  aggregate
outstanding   "Capital"  of  all  "Receivable   Interests"  under  the  Investor

to herein as the initial "Capital"  of  the  Receivable   Interest  then  being
purchased),  (ii) the date of such purchase  (which shall be a Business Day) and

Interest to be purchased.  The Agent shall notify the Seller whether the desired

purchase. Such notice of purchase shall be sent by telecopier, telex or cable to
all Banks concurrently and shall specify the date of such purchase,  each Bank's
Percentage  multiplied  by the  aggregate  amount of Capital  of the  Receivable
Interest  being  purchased,  the Fixed Period for such  Receivable  Interest and
whether  Yield for the Fixed Period for such  Receivable  Interest is calculated
based on the Eurodollar Rate (which may be selected only if such notice is given
at least two Business  Days prior to the purchase  date) or the  Alternate  Base
Rate.

                  (b) Prior to 2:00  P.M.,  New York City  time,  on the date of
each such purchase of a Receivable  Interest,  the Banks,  ratably in accordance
with  their  respective  Bank  Commitments,  shall,  upon  satisfaction  of  the
applicable conditions set forth in Sections 2.11 and 2.12, make available to the
Agent the amount of their  respective  purchases  by  deposit of the  applicable
amount in immediately  available funds to the Agent's Account and, after receipt
by the Agent of such funds, the Agent will cause such funds to be made available
to the  Seller in  immediately  available  funds at First  Security  Bank of New
Mexico, N.A., PNM General Fund, Account No. 651-53767-02, ABA 107000275 (or such
other  account  as the  Seller  may  specify by notice to the Agent from time to
time).

                  (c)  Effective on the date of each  purchase  pursuant to this
Section 2.02 and each  reinvestment  pursuant to Section 2.04, the Seller hereby
sells and  assigns to the Agent,  for the  benefit  of the Banks,  an  undivided
percentage  ownership  interest,  to the extent of the Receivable  Interest then
being  purchased,  in each Pool  Receivable  then  existing  and in the  Related
Security and Collections with respect thereto.

                  (d)  Notwithstanding  the  foregoing,  a  Bank  shall  not  be
obligated  to make  purchases  under this  Section 2.02 at any time in an amount

APA. Each Bank's obligation shall be several,  such that the failure of any Bank
to make available to the Seller any funds in connection  with any purchase shall
not relieve any other Bank of its  obligation,  if any,  hereunder to make funds
available on the date of such purchase, but no Bank shall be responsible for the
failure  of any  other  Bank to make  funds  available  in  connection  with any
purchase.

                  SECTIONS 2.03 through 2.04.  Incorporation by Reference.  Each

herein by this reference.

                  SECTION 2.08.  Increased  Costs.  (a) If CNAI, any Bank or any
Affiliate  thereof (each an "Affected  Person")  determines that compliance with
any law or regulation or any guideline or request from any central bank or other
governmental authority (whether or not having the force of law) affects or would
affect the amount of capital  required  or  expected  to be  maintained  by such
Affected  Person and such  Affected  Person  determines  that the amount of such
capital is increased by or based upon the  existence of any  commitment  to make
purchases  of or otherwise to maintain the  investment  in Pool  Receivables  or
interests  therein  related to this Agreement or to the funding  thereof,  other
commitments of the same type or under any  commitments  to the Investors,  then,
upon demand by such Affected Person (with a copy to the Agent), the Seller shall
immediately  pay to the Agent,  for the  account of such  Affected  Person (as a
third-party  beneficiary),  from  time  to time as  specified  by such  Affected
Person,  additional amounts sufficient to compensate such Affected Person in the
light of such circumstances,  to the extent that such Affected Person reasonably
determines  such  increase in capital to be allocable to the existence of any of
such  commitments.  A certificate as to such amounts submitted to the Seller and
the Agent by such  Affected  Person  shall be  conclusive  and  binding  for all
purposes, absent manifest error.

(other than any change by way of imposition or increase of reserve  requirements
referred  to in  Section  2.09)  in or in  the  interpretation  of  any  law  or
regulation  or (ii)  compliance  with any  guideline or request from any central
bank or other  governmental  authority (whether or not having the force of law),

purchasing,  or maintaining the ownership of Receivable  Interests in respect of
which Yield is computed by reference to the Eurodollar  Rate,  then, upon demand
by such Bank (with a copy to the Agent), the Seller shall immediately pay to the
Agent, for the account of such Bank (as a third-party beneficiary), from time to
time as specified by such Bank, additional amounts sufficient to compensate such
Bank for such  increased  costs,  to the extent  that such  Investor  reasonably
determines  such increase in costs to be allocable to such agreement to purchase
such  Receivable  Interests.  A certificate as to such amounts  submitted to the
Seller  and the Agent by such  Bank  shall be  conclusive  and  binding  for all
purposes, absent manifest error.

                  SECTION 2.09. Additional Yield on Receivable Interests Bearing
a Eurodollar  Rate. The Seller shall pay to any Bank, so long as such Bank shall
be required under  regulations of the Board of Governors of the Federal  Reserve
System to maintain  reserves with respect to liabilities or assets consisting of
or including Eurocurrency Liabilities, additional Yield on the unpaid Capital of
each  Receivable  Interest of such Bank  during each Fixed  Period in respect of
which Yield is computed by  reference  to the  Eurodollar  Rate,  for such Fixed
Period,  at a rate per annum equal at all times  during such Fixed Period to the
remainder  obtained by subtracting (i) the Eurodollar Rate for such Fixed Period
from (ii) the rate  obtained by dividing  such  Eurodollar  Rate  referred to in
clause  (i) above by that  percentage  equal to 100% minus the  Eurodollar  Rate
Reserve  Percentage of such Bank for such Fixed Period,  payable on each date on
which Yield is payable on such Receivable Interest.  Such additional Yield shall
be  determined by such Bank and notice  thereof given to the Seller  through the
Agent within 30 days after any Yield  payment is made with respect to which such
additional  Yield  is  requested.  A  certificate  as to such  additional  Yield
submitted  to the  Seller  and the Agent by such Bank  shall be  conclusive  and
binding for all purposes, absent manifest error.

                  or deemed made by the Seller (or any of its officers) under or

                  any  Receivable  in, or purporting  to be in, the  Receivables
                  Pool (including,  without limitation,  a defense based on such
                  Receivable  or the related  Contract not being a legal,  valid
                  and binding obligation of such Obligor  enforceable against it
                  in accordance  with its terms),  or any other claim  resulting

                  merchandise  or services or relating to collection  activities
                  with respect to such Receivable (if such collection activities
                  were performed by the Seller or any of its  Affiliates  acting
                  as  Collection  Agent).  Without  in any manner  limiting  the

                  the Seller shall be entitled,  at its election,  to assume the
                  defense of, or otherwise to contest, any such dispute,  claim,
                  offset or defense.  The Indemnified  Party will cooperate with
                  the Seller,  at the Seller's sole cost, in any such defense or
                  contest  undertaken  by the  Seller.  In the event the  Seller
                  assumes such defense, or undertakes such contest, the

assigns.

(collectively, the "Agreements").

                  WHEREAS,  the Seller and the Agent are parties to that certain
Collection  Agent  Agreement,  dated as of  December  21,  1993  (the  "Original

Agreement.

                  WHEREAS,  it is a condition  precedent  to the  execution  and

Related Security and the related Contracts.

                  (b) The Collection  Agent shall  administer the Collections in

                  (c) If no Event of Termination or event that but for notice or
lapse  of time or both  would  constitute  an Event of  Termination  shall  have
occurred and be continuing,  the Seller,  while it is the Collection Agent, may,
in  accordance  with the Credit and  Collection  Policy,  extend the maturity or

                  (d) The Collection Agent shall hold in trust and, upon request
of the Agent,  shall legend  appropriately  for the Seller and each Investor and

notify the Obligors of Receivables,  at any time and at the Seller's expense, of
the ownership of such Receivables under the Agreements.

                  (b) At any time  following  the  designation  of a  Collection
Agent other than the Seller pursuant to Section 2:

                           (i)  The  Agent  may  direct  the  Obligors  of  Pool
                  Receivables  that all payments  thereunder be made directly to
                  the Agent or its designee.

                           (ii) The Seller shall,  at the Agent's request and at
                  the Seller's expense,  notify each Obligor of Pool Receivables
                  of the ownership of Receivable  Interests under the Agreements
                  and direct that  payments be made directly to the Agent or its
                  designee.

                           (iii) The Seller shall, at the Agent's request and at
                  the  Seller's  expense,  (A)  assemble  all of the  documents,
                  instruments and other records (including,  without limitation,
                  computer  tapes and disks) that evidence or relate to the Pool
                  Receivables,  and the related  Contracts and Related Security,
                  or that are  otherwise  necessary  or desirable to collect the
                  Pool  Receivables,  and shall make the same  available  to the
                  Agent at a place  selected by the Agent or its  designee,  and
                  (B) segregate all cash, checks and other instruments  received
                  by it  from  time  to time  constituting  Collections  of Pool
                  Receivables in a manner  acceptable to the Agent and, promptly
                  upon  receipt,  remit all such cash,  checks and  instruments,
                  duly endorsed or with duly executed  instruments  of transfer,

                  Seller  authorizes  the Agent to take any and all steps in the
                  Seller's  name and on behalf of the Seller that are  necessary
                  or desirable,  in the  determination  of the Agent, to collect

                  amounts  due under the Pool  Receivables,  including,  without
                  limitation,  endorsing  the Seller's  name on checks and other
                  instruments  representing  Collections of Pool Receivables and
                  enforcing the Pool  Receivables  and the Related  Security and
                  related Contracts.

                  SECTION 5. Further Assurances. (a) The Seller agrees from time
to time, at its expense, promptly to execute and deliver all further instruments
and  documents,  and to take  all  further  actions,  that may be  necessary  or
desirable, or that the Agent may reasonably request, to perfect, protect or more
fully evidence the Receivable  Interests  purchased under the Agreements,  or to
enable the  Investor  and the Banks or the Agent to exercise  and enforce  their
respective  rights  and  remedies  hereunder  or under the  Agreements.  Without
limiting  the  foregoing,  the Seller will,  upon the request of the Agent,  (i)
execute  and file such  financing  or  continuation  statements,  or  amendments
thereto,  and such other  instruments  and  documents,  that may be necessary or
desirable,  or that the Agent may  reasonably  request,  to perfect,  protect or
evidence  such  Receivable  Interests;  (ii)  mark  conspicuously  each  invoice
evidencing  each  Pool  Receivable  and  the  related  Contract  with a  legend,
acceptable to the Agent,  evidencing that Receivable Interests therein have been
sold; and (iii) mark its master data  processing  records  evidencing  such Pool
Receivables and related Contracts with such a legend.

                  (b) The  Seller  authorizes  the  Agent to file  financing  or
continuation  statements,   and  amendments  thereto  and  assignments  thereof,
relating to the Pool Receivables and the Related Security, the related Contracts
and the  Collections  with respect  thereto  without the signature of the Seller
where  permitted by law. A photocopy  or other  reproduction  of the  applicable
Agreement  and this Amended and Restated  Collection  Agent  Agreement  shall be
sufficient as a financing statement where permitted by law.

                  SECTION 6. Collection Agent Fee. The Collection Agent shall be
paid a collection agent fee of 1% per annum on the average daily Capital of each
Receivable Interest, from the date of purchase of such Receivable Interest until

                                        5

DOC #1180048.NY




the later of the Termination  Date for such  Receivable  Interest or the date on
which  such  Capital  is  reduced  to  zero,  payable  on the  last  day of each
Settlement Period for such Receivable Interest. Upon three Business Days' notice
to the Agent, the Collection Agent (if not the Seller or its designee) may elect
to be paid,  as such fee,  another  percentage  per annum on the  average  daily
Capital  of  such  Receivable  Interest,  but in no  event  in  excess  for  all
Receivable  Interests  relating  to a  single  Receivables  Pool  of 110% of the
reasonable  costs and  expenses of the  Collection  Agent in  administering  and
collecting the Receivables in such  Receivables  Pool. The collection  agent fee
shall be payable only from Collections  pursuant to, and subject to the priority
of payment set forth in, Section 2.04 of each Agreement.

                  SECTION 7.  Confidentiality.  (a) Unless otherwise required by
applicable  law or  regulation,  the  Collection  Agent  agrees to maintain  the
confidentiality of the Agreements and this Amended and Restated Collection Agent
Agreement  (and all drafts  thereof) in  communications  with third  parties and
otherwise;  provided  that they may be  disclosed  to (i) third  parties  to the
extent  such   disclosure   is  made   pursuant  to  a  written   agreement   of
confidentiality in form and substance reasonably  satisfactory to the Agent, and
(ii) the Collection Agent's legal counsel and auditors if they agree (which they
may do orally) to hold it confidential.

                  (b)  The   Collection   Agent  also  agrees  to  maintain  the
confidentiality  of any  information  it receives  from the Seller,  its agents,
affiliates or representatives in connection with the Agreements and this Amended
and  Restated  Collection  Agent  Agreement  or  any  audit  or  otherwise  (the
"Confidential   Information");   provided,  however,  that  there  shall  be  no
obligation of confidentiality  in respect of any Confidential  Information which
may be generally available to the public.


                  SECTION 8.  Rights and Remedies.  (a)  If the Collection Agent
fails to perform any of its obligations hereunder or under the Agreements, the

                                        6

DOC #1180048.NY




Agent may (but shall not be required to) itself  perform,  or cause  performance
of, such obligation;  and the Agent's costs and expenses  incurred in connection
therewith shall be payable by the Seller (if the Collection  Agent that fails to
perform is the Seller or its designee).

                  (b) The  exercise by the Agent on behalf of the  Investor  and
the Banks of their rights  hereunder and under the Agreements  shall not release
the Collection  Agent or the Seller from any of their duties or obligations with
respect to any Pool  Receivables  or under the  related  Contracts.  Neither the
Agent,  the Banks nor the Investor  shall have any  obligation or liability with
respect to any Pool Receivables or related  Contracts,  nor shall any of them be
obligated to perform the obligations of the Seller thereunder.

                  (c)  The  Seller  shall  perform  its  obligations  under  the
Contracts  related to the Pool  Receivables  to the same extent as if Receivable
Interests had not been sold.

                  (d)  The   Investor   and  the  Banks  shall  be  third  party
beneficiaries of this Amended and Restated Collection Agent Agreement.

                  SECTION 9. Term of  Agreement.  The term of this  Amended  and
Restated  Collection  Agent Agreement  shall be coterminous  with the Agreements
unless earlier  terminated upon notice by any party hereto.  Upon termination of
this Amended and Restated Collection Agent Agreement, the Collection Agent shall
remit all funds then held by it to the parties as  required  by Section  2.04 of
the Agreements.

                  SECTION  10.  Execution  in  Counterparts.  This  Amended  and
Restated  Collection  Agent  Agreement may be executed by the parties  hereto in
separate counterparts,  each of which shall be deemed to be an original, and all
such counterparts shall together constitute but one and the same instrument.

Amended and Restated  Collection Agent Agreement,  unless any purported consent,
approval  or waiver is  expressly  set forth in writing  and signed by the party
giving the  consent,  approval  or  waiver.  No failure on the part of any party
hereto  to  exercise,  and no delay in  exercising,  any right  hereunder  shall
operate as a waiver  thereof  nor shall any single or  partial  exercise  of any
right hereunder  preclude any other or further  exercise thereof or the exercise
of any other right or be  construed as a waiver to or of any other breach of the
same or any other covenant, condition or duty.

                  SECTION  13.   Notices,   Etc.   (a)  Except  when   telephone

and communications hereunder shall be in writing (which shall include electronic
transmission), shall be personally delivered, express couriered,  electronically

provided  herein,  be effective  when  received at the address  specified on the

                  SECTION 16.  Assignability.  This Agreement and the rights and
obligations hereunder may not be assigned by either party without the prior
written consent of the other party hereto.
