As of December 1, 2000

TO EACH HOLDER OF SERIES C
  CONVERTIBLE PREFERRED STOCK,
  $.0001 PAR VALUE ("SERIES C STOCK"),
  OF NEWCHECK CORPORATION:

	Under the terms of the Amended and Restated Securityholders
Agreement dated February 11, 2000 (the "Securityholders
Agreement") of NewCheck Corporation (the "Company"), each of you
holds a right of first offer to acquire additional securities
proposed to be issued by the Company in the applicable
circumstances. Accordingly, we will communicate with you shortly
regarding the resolution of the Company's financing plan for the
near term and any new securities acquisitions to which you are
entitled.

	As an interim measure, in order to provide liquidity
adequate to sustain the Company's operations, we request that
you enter into the commitment, to be evidenced by this letter,
to fund your share of: (i) an aggregate of $1,000,000 in short-
term funds (the "Initial Loan") that may be drawn against by the
Company, on one or more occasions, on or after December 15, 2000
and for 60 days thereafter, (ii) an additional aggregate of
$2,000,000 in short-term funds (the "First Supplemental Loan"),
that may be drawn against by the Company, on one or more
occasions, on or after January 15, 2001 and for 60 days
thereafter, and (iii) an additional aggregate of $2,000,000 in
short-term funds (the "Second Supplemental Loan"), that may be
drawn against by the Company, on one or more occasions, on or
after March 1, 2001 and for 90 days thereafter (the Initial
Loan, the First Supplemental Loan and the Second Supplemental
Loan are together referred to as the "Loans").

Your pro rata share of each of the Loans (calculated on the
basis of the outstanding Series C Stock and shares subject to
issuance under the Company's convertible notes outstanding) is
set forth opposite your name on Annex 1 to this letter. In the
event any share of the Loans is not committed on or prior to
December 1, 2000 (such date subject to extension at the
discretion of the Company's Board of Directors), such share may
be assigned, at the discretion of the Board, to any other
shareholder.

	Subject to your countersignature of this letter in the
space below provided for that purpose, the Company may require
you to fund your share of the Loans, respectively, in each
instance by written notice to you. Each funding call will be
made by the Company pro rata to the committing shareholders. In
the case of each Loan, your portion thereof will be evidenced by
the Company's promissory note to you, dated the first date on
which the Company may draw down such Loan and due 90 days after
the last date on which the Company may draw down such Loan as
aforesaid, which will accrue interest at the rate per annum of
9% and be subject to prepayment at the option of the Company.

	Any and all of the Loans made by you as aforesaid will, at
the option of the Company (as determined by its Board of
Directors and approved by the holders [the "Required Holders"]
of the Company's notes representing in excess of 75% of the
aggregate principal amount of the Loans outstanding), be applied
to the acquisition for your account of shares of Series C Stock
at a price per share equal to its fair value (as determined by
the Board and approved by the Required Holders). In the event
you currently hold any of the Company's notes convertible into
Series C Stock, the indebtedness so applied will be allocated
between such shares and an increase in the principal amount of
your convertible note in appropriate proportion to your current
holdings of shares and notes. Any interim note or notes issued
in connection with funding hereunder will be prepared by the
Company so as to evidence in reasonable manner the terms of the
Loans set forth herein.

	Your execution below will also constitute your consent to
the consummation by the Company of the transactions described
herein (including issuance of a number of shares of Series C
Stock sufficient to effectuate such transactions),
notwithstanding any of the covenants contained in the Company's
Stock and Convertible Note Purchase Agreement dated February 11,
2000 and free of any additional rights-of-first offer under the
Securityholders Agreement.  You further agree to execute and
deliver any such additional documentation, and deliver such
additional consents, reasonably requested by the Company to
effectuate the transactions contemplated herein.

	Kindly confirm your agreement to the foregoing by
countersigning this letter in the space below provided and
returning it to the undesignated, whereupon your commitment
shall remain in effect through the periods set forth above.

						Very truly yours,

						NEWCHECK CORPORATION

this Note has been duly executed and delivered by the Maker and

and discharged promptly, all taxes, assessments and
governmental charges or levies imposed upon it or upon its
income or upon any of its property, real, personal or mixed,

(including claims for labor, materials and supplies which, if
unpaid, might by law become a lien or charge upon its
property), provided, however, that the Maker shall not be
required to pay any such tax, assessment, charge, levy or
claim if the amount, applicability or validity thereof shall
currently be contested in good faith by appropriate
proceedings and if the Maker shall have set aside on its
books reserves (segregated to the extent required by sound
accounting practice) reasonably deemed by it adequate with
respect thereto; and

			(b) do or cause to be done all things necessary or
appropriate to preserve and keep in full force and effect its

whatsoever and whether such happening shall be voluntary or
involuntary or come about or be effected by operation of law or
pursuant to or in compliance with any judgment, decree or order of
any court or any order, rule or regulation of any administrative
or governmental body) and be continuing at the time of such

payment of the principal of this Note when and as the same shall
become due and payable, whether at maturity, by acceleration or
otherwise;

		(b) if default shall be made in the due and punctual
payment of any interest on this Note when and as such interest
shall become due and payable;

		(c) if default shall be made in the performance or
observance of any of the other covenants, agreements or conditions
of the Maker contained in this Note, and such default shall have
continued for a period of 30 days after notice thereof by the
holder hereof to the Maker;

		(d) if any representation made by the Maker contained

made, or if this Note shall cease to be enforceable in accordance
with its terms against the Maker, or the Maker shall so state in
writing;

		(e)	if an Event of Default under any of the other Notes

cause the holder or holders thereof to cause such obligations,
respectively, to become due prior to the date of stated maturity

Note, an order, judgment, or decree appointing, without the
consent of the Maker, a receiver of the Maker or of the whole or
any substantial part of its property, or approving a petition
filed against it seeking reorganization or arrangement of the
Maker under the federal bankruptcy laws or any other applicable
law or statute of the United States of America or any State,
district or territory thereof, and such order, judgment or decree
shall not be vacated or set aside or stayed within 60 days from
the date of entry thereof; or

		(h) if, under the provisions of any other law for the
relief or aid of debtors, any court of competent jurisdiction
shall assume custody or control of the Maker or of the whole or
any substantial part of its property and such custody or control
shall not be terminated or stayed within 60 days from the date of
assumption of such custody or control.

		8.2 In the case any one or more of the Events of Default
specified in Section 8.1 hereof shall have occurred and be
continuing, the holder of this Note may proceed to protect and
enforce its rights either by suit in equity and/or by action at
law, whether for the specific performance of any covenant or
agreement contained in this Note, or the holder of this Note may
at its option exercised by written notice to the Maker at its
principal executive offices declare the unpaid principal balance
hereof, together with all accrued interest thereon, immediately
due and payable, and otherwise proceed to enforce the payment of
all sums due upon this Note or to enforce any other legal or
equitable right of the holder of this Note.  In the event an Event
of Default shall have occurred and the holder of this Note shall
employ attorneys, or incur other costs and expenses for the
collection of payments due or to become due, or for the
enforcement or performance or observance of any obligation or
agreement of the Maker under this Note, the Maker agrees that it
will pay to the holder, on demand, the reasonable fees of such
attorney together with all other costs and expenses incurred by

Note is intended to be exclusive of any other remedy and each and
every such remedy shall be cumulative and shall be in addition to
every other remedy given hereunder or now or hereafter existing at
law or in equity or by statute or otherwise.

		8.4 	No course of dealing between the Maker and the
holder of this Note or any delay on the part of the Holder hereof
in exercising any rights hereunder shall operate as a waiver of
any rights of the holder hereof.

		SECTION 9. Replacement of Note.  Upon receipt by the
Maker of evidence satisfactory to it of the loss, theft,
destruction or mutilation of this Note, and (in case of loss,
theft or destruction) of indemnity satisfactory to it, and upon
surrender and cancellation of this Note, if mutilated, the Maker,
upon reimbursement to it of all reasonable expenses incidental
thereto, will make and deliver a new Note, of like tenor, in lieu
of this Note. Any Note made and delivered in accordance with the
provisions of this Section 9 shall be dated as of the date to
which interest has been paid on this Note.

		SECTION 10. Captions. Captions and section titles
contained herein are for the purpose of convenience of reference
only and are not intended to define, limit, extend or describe the
scope of this Note or the intent of any provision hereof.

invalid, illegal or unenforceable in any respect, such invalidity,
illegality or unenforceability shall not affect any other

such invalid, illegal or unenforceable provision had never been
contained herein.

currently be contested in good faith by appropriate
proceedings and if the Maker shall have set aside on its
books reserves (segregated to the extent required by sound
accounting practice) reasonably deemed by it adequate with
respect thereto; and

relief or aid of debtors, any court of competent jurisdiction
shall assume custody or control of the Maker or of the whole or
any substantial part of its property and such custody or control
shall not be terminated or stayed within 60 days from the date of
assumption of such custody or control.

		8.2 In the case any one or more of the Events of Default
specified in Section 8.1 hereof shall have occurred and be
continuing, the holder of this Note may proceed to protect and
enforce its rights either by suit in equity and/or by action at
law, whether for the specific performance of any covenant or
agreement contained in this Note, or the holder of this Note may

principal executive offices declare the unpaid principal balance
hereof, together with all accrued interest thereon, immediately
due and payable, and otherwise proceed to enforce the payment of
all sums due upon this Note or to enforce any other legal or

thereto, will make and deliver a new Note, of like tenor, in lieu
of this Note. Any Note made and delivered in accordance with the
provisions of this Section 9 shall be dated as of the date to
