                  POST-PETITION SENIOR SECURED PROMISSORY NOTE
                  --------------------------------------------



$66,000.00                                       As of December 17, 2003



         FOR VALUE RECEIVED, the undersigned, eCLICKMD, INC., a Nevada
corporation (the "Borrower"), promises to pay YORK AVENUE HOLDING COMPANY, a
Delaware corporation (the "Lender") the sum of Sixty Six Thousand and no/100
Dollars ($66,000.00) (the "Principal Amount") with interest from the date of
advancement on the unpaid balance hereof from time to time remaining unpaid at a
rate equal to five (5%) percent per annum.

         This Note is issued pursuant to an order of the United States
Bankruptcy Court for the Western District of Texas, dated as of October 6, 2003
in Case No. 03-12387-FRM approving post-petition financing by Borrower, and
granting Lender a superpriority lien on effectively all of the assets of
Borrower.

         Notwithstanding any provision to the contrary contained herein or
elsewhere, this Note is subject and entitled to certain terms, conditions,
covenants and agreements contained in the Court's Order Approving Post-Petition
Financing. Reference to that Order shall in no way impair the absolute and
unconditional obligation of the Borrower to pay both the Principal Amount and
interest as provided herein.

         1.       Principal and Payments. This Note shall mature and the
Principal Amount shall be due and payable immediately upon demand ("Demand") by
the Borrower. The date of the giving by the Borrower of Demand shall be referred
to herein as the "Maturity Date"). All payments hereunder shall be payable to
the Lender. All payments hereunder shall be payable in lawful money of the
United States of America which shall be legal tender for public and private
debts at the time of payments. Each payment by the Borrower pursuant to this
Note shall be made without set-off or deduction and in immediately available
funds. All payments of the Principal Amount and interest under this Note (and
all other amounts payable hereunder) shall be made to Lender on or before the
Maturity Date at the address of Lender hereinbefore set forth or, at Lender's
request, to Lender at such other address as Lender may, from time to time,
designate in writing. If any payment hereunder becomes due on a Saturday, Sunday

<PAGE>

or legal holiday, such payment shall become due on the next business day. The
Borrower (i) waives presentment, demand, protest or notice of any kind in
connection with this Note (except as specifically provided elsewhere in this
Note) and (ii) agrees, in the event of an Event of Default (as hereinafter
defined), to pay to the holder of this Note, on demand, all costs and expenses
(including legal fees and expenses) incurred in connection with the enforcement
and collection of this Note.

         2.       Interest. Subject to prior conversion as set forth in Section
3, the Borrower shall pay interest on the outstanding Principal Amount of this
Note on the Maturity Date. Interest on this Note shall accrue on the outstanding
principal amount from the date of issuance until repayment of the Principal
Amount and payment of all accrued interest in full. Interest shall be computed
on the basis of a 360-day year of twelve 30-day months. In the event this Note
is not repaid on the Maturity Date, the rate of interest applicable to the
unpaid Principal Amount shall be adjusted to thirteen (13%) percent per annum
from the date a default in this Note first occurs until repayment, provided,
that in no event shall the interest rate exceed the highest lawful rate as
provided below. All agreements herein are expressly limited so that in no
contingency or event whatsoever, whether by reason of advancement of the
proceeds hereof, acceleration of maturity of the unpaid principal balance
hereof, or otherwise, shall the amount paid or agreed to be paid to the Lender
for the use, forbearance or detention of the money to be advanced hereunder
exceed the highest lawful rate permissible under applicable usury laws. If, from
any circumstances whatsoever, fulfillment of any provision in this Note at the
time performance of such provision shall be due, shall involve transcending the
limit of validity prescribed by law that a court of competent jurisdiction may
deem applicable hereto, then, ipso facto, the obligation to be fulfilled shall
be reduced to the limit of such validity and if from any circumstance the Lender
shall ever receive as interest an amount that would exceed the highest lawful
rate, such amount that would be excessive interest shall be applied to the
reduction of the unpaid principal balance due hereunder and not to the payment
of interest.

         3.       Events of Default.

                  A.       The term "Event of Default" shall mean any of the
events set forth in this Section 5A:

                           (i)      Non-Payment of Obligations. The Borrower
shall default in the payment of the Principal Amount or accrued interest on this
Note as and when the same shall become due and payable, whether by acceleration
or otherwise.

                           (ii)     Conversion. The Borrower shall voluntarily
or involuntarily permit or suffer the conversion of its chapter 11 case to a
case under chapter 7 of the United States Bankruptcy Code.

                           (iii)    Liens and Judgments. The Borrower shall
hereafter create, incur, assume or suffer to exist any mortgage, pledge,
hypothecation, assignment, security interest, encumbrance, lien (statutory or
other), preference, priority or other security agreement or preferential
arrangement of any kind or nature whatsoever (including any conditional sale or

                                      -2-
<PAGE>

other title retention agreement and any financing lease) (each, a "Lien") upon
any of its property, revenues or assets, whether now owned or hereafter
acquired.

                  B.       Action if Event of Default. If any Event of Default
shall occur for any reason, whether voluntary or involuntary, and be continuing,
the Lender may, upon notice to the Borrower, declare all or any portion of the
outstanding Principal Amount, together with interest accrued on this Note, to be
due and payable and any or all other obligations hereunder to be due and
payable, whereupon the full unpaid Principal Amount hereof, such accrued
interest and any and all other such obligations which shall be so declared due
and payable shall be and become immediately due and payable, without further
notice, demand, or presentment.

         4.       Security Interest. Payment of this Note is secured by the
Post-Petition Security Agreement. Additional rights of Lender in connection with
this Note are set forth in the Security Agreement.

         5.       Notices. All notices, approvals, requests, demands and other
communications hereunder shall be given in accordance with the notice provision
of the Agreement.

         6.       Waiver and Amendment.

                  A.       Any amendment, supplement or modification of or to
any provision of this Note, any waiver of any provision of this Note and any
consent to any departure by the Borrower from the terms of any provision of this
Note, shall be effective (i) only if it is made or given in writing and signed
by the Borrower and each Lender and (ii) only in the specific instance and for
the specific purpose for which made or given.

                  B.       No failure or delay on the part of the Lender in
exercising any power or right under this Note shall operate as a waiver thereof,
nor shall any single or partial exercise of any such power or right preclude any
other or further exercise thereof or the exercise of any other power or right.
No notice to or demand on the Borrower in any case shall entitle it to any
notice or demand in similar or other circumstances. No waiver or approval by the
Lender shall, except as may be otherwise stated in such waiver or approval, be
applicable to subsequent transactions. No waiver or approval hereunder shall
require any similar or dissimilar waiver or approval thereafter to be granted
hereunder.

                  C.       To the extent that the Borrower makes a payment or
payments to the Lender, and such payment or payments or any part thereof are
subsequently for any reason invalidated, set aside and/or required to be repaid
to a trustee, receiver or any other party under any bankruptcy law, state or
federal law, common law or equitable cause, then to the extent of such recovery,
the obligation or part thereof originally intended to be satisfied, and all
rights and remedies therefor, shall be revived and continued in full force and
effect as if such payment had not been made or such enforcement or setoff had
not occurred.

                  D.       After any waiver, amendment or supplement under this
Section 7 becomes effective, the Borrower shall mail to the Holders a copy
thereof.

         7.       Miscellaneous.

                  A.       Parties in Interest; Right of Lender to Assign Note.
All covenants, agreements and undertakings in this Note binding upon the
Borrower or the Lender shall bind and inure to the benefit of the successors and
permitted assigns of the Borrower and the Lender, respectively, whether so
expressed or not. The Lender shall have the right to assign this Note and the
Borrower shall take any and all action reasonably requested by the Lender to
facilitate the assignment of this Note and each assignee shall be deemed the
"Lender" of the portion of the Note so assigned. The Borrower may not assign
this Note (and/or its obligations pursuant to this Note).

                  B.       Governing Law, Etc. This Agreement shall be governed
by and construed solely in accordance with the internal laws of the State of New

prevailing therein shall be entitled to payment from the other party hereto of
its reasonable counsel fees and disbursements.

                  C.       Waiver of Jury Trial. THE LENDER AND THE BORROWER
HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHTS THEY MAY HAVE
