                           CONVERTIBLE PROMISSORY NOTE

$200,000                                                       December 5, 2003

         Medical Nutrition USA, Inc., a Delaware corporation (the "Company"),
for value received, hereby promises to pay to ________ ("Lender"), on the
Maturity Date (as hereinafter defined), the principal amount of Two Hundred
Thousand Dollars ($200,000). Unless converted into shares of the Company's
capital stock, all sums of principal and interest (if any) due pursuant to this
Note shall be due and payable in a single installment on the third (3rd)
anniversary of the date of this Note ("Maturity Date") at the principal office
of the Company at 10 West Forest Avenue, Englewood, New Jersey 07631 in currency
of the United States of America. Upon fifteen (15) days' prior written notice to
the Lender, the Company may, without penalty or additional fees, prepay in whole
or in part the principal sum, plus accrued interest to date of payment, of this
Note. The obligations of the Company under this note are unsecured.

         1. Interest. This Note shall accrue simple interest at a rate tied to
the increase in projected Product (as defined below) sales resulting from the
publication and dissemination of the Clinical Trial (as defined below) results
as follows: For every one percent (1%) increase in actual Product sales over the
$9,043,000 in projected sales for the period commencing July 1, 2004 and ending
on July 1, 2005 (the "Sales Period"), the Note will accrue one half percent
(1/2%) simple interest up to a maximum of ten percent (10%) simple interest per
annum. By way of example, if actual Product sales for the Sales Period exceed
the projected sales by sixteen percent (16%), the Note would accrue simple
interest at the rate of eight percent (8%) per annum. Interest (if any) will
accrue from the date of issuance of this Note through and including the first to
occur of the Maturity Date or the date this Note is converted pursuant to
Section 4 below. For purposes of this Note, (a) the term "Product" means a
branded nutritional supplement called Pro-Stat(TM), which is an enzymatic
hydrolyzed protein supplement used to treat unintended weight loss, malnutrition
and pressure ulcers; and (b) the term "Clinical Trial" means a clinical trial of
the Product on sufficient numbers of patients to establish the Product's safety
and efficacy for the desired claims and indications, as more specifically
defined by the rules of the United States Food and Drug Administration or its
equivalent.
<PAGE>

         2. Waiver. The Company and any and each other person or entity liable
for the payment or collection of this Note expressly waives demand and
presentment for payment, notice of nonpayment, protest, notice of protest,
notice of dishonor, bringing of suit and diligence in taking any action to
collect amounts called for under this Note, and shall be directly and primarily
liable for the payment of all sums owing and to be owing on this Note,
regardless of and without any notice, diligence, act or omission as or with
respect to the collection of any amount called for under this Note.

         3. Costs of Collection. The Company agrees to pay all reasonable costs,
including reasonable attorneys' fees, incurred by the Lender in collecting or
enforcing payment of this Note in accordance with its terms.

         4. Conversion.

                  a. The entire unpaid balance of principal of this Note, and
         all accrued and unpaid interest (if any) on this Note, may be converted
         at any time prior to the Maturity Date, at the option of the Lender
         upon written notice (and delivery of this Note) to the Company, into
         shares of Common stock of the Company at a conversion price per share
         equal to $2.25.

                  b. As promptly as practicable after the conversion of this
         Note, the Company at its expense will issue and deliver to the Lender,
         upon surrender of this Note, a certificate or certificates for the
         number of full shares of equity securities issuable upon such
         conversion. No fractional shares shall be issued in connection with any
         conversion under this Note, but in lieu of such fractional shares, the
         Company shall round up the number of shares to be received upon
         conversion of this Note to the next whole share of stock.

         5. Usury Savings Clause. Notwithstanding any provision of this Note,
the Company shall not and will not be required to pay interest at a rate or any
fee or charge in an amount prohibited by applicable law. If interest or any fee
or charge payable on any date would be prohibited, then such interest, fee or
charge will be automatically reduced to the maximum amount that is not
prohibited. In the event that Lender receives payment of any interest, fee, or
charge that would cause the amount so received to exceed the maximum amount
permitted under applicable law, then, to the extent that the amount so received
exceeds the maximum amount permitted under applicable law: (a) in the first
instance, the amount received shall be applied to principal and (b) in the
second instance, in the event that the principal amount of this Note has been
paid in full, the remaining amount so received shall be deemed to be a loan from
the Company to Lender, repayable upon the demand of the Company with interest at
the legal rate from the date of Lender's receipt of each payment in excess
interest, fees, or charges.

         6. Representations of Lender.

                  a. Acquisition for Personal Account. Lender represents and
         warrants that he is acquiring this Note and the Conversion Shares (as
         defined below) (the "Securities") solely for his own account for
         investment and not with a view to or for sale or distribution thereof.
         Lender also represents that the entire legal and beneficial interests
         he may acquire in the Securities are being acquired for, and will be
         held for, Lender's account only.
<PAGE>

                  b. Securities Are Not Registered. Lender understands that the
         Securities have not been registered under the Securities Act of 1933,
         as amended, on the basis that no distribution or public offering of the
         securities of the Company is to be effected. Lender realizes that the
         basis for the exemption may not be present if, notwithstanding his
         representations, Lender has a present intention of acquiring the
         securities for a fixed or determinable period in the future, selling
         (in connection with a distribution or otherwise), granting any
         participation in, or otherwise distributing the Securities. Lender has
         no such present intention.

                  c. Accredited Investor. Lender is an "accredited investor"
         within the meaning of Securities and Exchange Commission ("SEC") Rule
         501 of Regulation D, as presently in effect.

         7. Covenants of the Company.

                  a. Authorization. All corporate action on the part of the
         Company, its directors and its stockholders necessary for the
         authorization, execution, delivery and performance of this Note by
         Company and the performance of the Company's obligations hereunder,
         including the issuance and delivery of this Note and the shares of
         equity securities issuable upon conversion of this Note (the
         "Conversion Shares") and the reservation of the Conversion Shares has
         been taken or will be taken prior to the issuance of such Conversion
         Shares. This Note, when executed and delivered by the Company, shall
         constitute a valid and binding obligation of the Company enforceable in
         accordance with its terms, subject to laws of general application
         relating to bankruptcy, insolvency and the relief of debtors. The
         Conversion Shares, when issued in compliance with the provisions of
         this Note, will be validly issued, fully paid and nonassessable and
         free of any liens or encumbrances.

                  b. No Impairment. Except and to the extent as waived or
         consented to by Lender, the Company will not, by amendment of its
         Certificate of Incorporation or through any reorganization, transfer of
         assets, consolidation, merger, dissolution, issue or sale of securities
         or any other voluntary action, avoid or seek to avoid the observance or
         performance of any of the terms to be observed or performed hereunder
         by the Company, but will at all times in good faith assist in the
         carrying out of all the provisions of this Note and in the taking of
         all such action as may be necessary or appropriate in order to protect
         the conversion rights of Lender against impairment.

         8. Default.  Each of the following events shall be an "Event of
         Default" hereunder:

                  a. the Company fails to pay timely any of the principal amount
         due under this Note or any accrued interest or other amounts due under
         this Note on the date the same becomes due and payable or within twenty
         (20) business days thereafter;

                  b. the Company files any petition or action for relief under
         any bankruptcy, reorganization, insolvency or moratorium law or any
         other law for the relief of, or relating to, debtors, now or hereafter
<PAGE>

         in effect, or makes any assignment for the benefit of creditors or
         takes any corporate action in furtherance of any of the foregoing; or

                  c. an involuntary petition is filed against the Company
         (unless such petition is dismissed or discharged within ninety (90)
         days) under any bankruptcy statute now or hereafter in effect, or a
         custodian, receiver, trustee, assignee for the benefit of creditors (or
         other similar official) is appointed to take possession, custody or
         control of any property of the Company.

                  Upon the occurrence of an Event of Default hereunder, all
         unpaid principal, accrued interest and other amounts owing hereunder
         shall, at the option of Lender, be immediately due, payable and
         collectible by Lender pursuant to applicable law.

         9. Miscellaneous

                  a. The Company hereby agrees that no failure on the part of
         the Lender to exercise any power, right or privilege hereunder, or to
         insist upon prompt compliance with the terms hereof, shall constitute a
         waiver thereof.

                  b. The Lender shall not be deemed, by any act of omission or
         commission, to have waived any of his rights or remedies hereunder
         unless such waiver is in writing and signed by the Lender, and then
         only to the extent specifically set forth in writing. A waiver with
         reference to one event shall not be construed as continuing or as a bar
         to or waiver of any right or remedy as to a subsequent event. No delay
         or omission of the Lender to exercise any right, whether before or
         after an Event of Default, shall impair any such right or shall be
         construed to be a waiver of any right or default, and the acceptance at
         any time by the Lender of any past due amounts shall not be deemed to
         be a waiver of the right to require prompt payment when due of any
         other amounts then or thereafter due and payable.

                  c. The remedies of the Lender in this Note or at law or in
         equity shall be cumulative and concurrent, and may be pursued singly,
         successively or together at the sole discretion of the Lender, and may
         be exercised as often as occasion therefor shall occur; and the failure
         to exercise any such right or remedy shall in no event be construed as
         a waiver or release thereof.

                  d. Lender shall not become or be deemed a partner or joint
         venturer with the Company by reason of any provisions of this Note.

                  e. If any amount of principal or interest on or in respect of
         this Note becomes due and payable on any date which is not a Business
         Day, such amount shall be payable on the next preceding Business Day.
         "Business Day" means any day other than a Saturday, Sunday, statutory
         holiday or other day on which banks in the State of Delaware are
         required by law to close or are customarily closed.

                  f. If any of the provisions of this Note or the application
         thereof to any persons or circumstances shall, to any extent, be held
         to be invalid or unenforceable, the remainder of this Note by the
         application of such provision or provisions to persons or circumstances
<PAGE>

         other than those as for whom or of which it is held invalid or
         unenforceable shall not be affected thereby, and every provision of
         this Note shall be valid and enforceable to the fullest extent
         permitted by law.

                  g. The terms of this Note shall apply to, inure to the benefit
         of, and bind all parties hereto, their heirs, legatees, devisees,
         administrators, executors, successors, assigns or any entity formed as
         a result of the Company reincorporating in another jurisdiction.
         Notwithstanding any provision of this Note to the Contrary, in addition
         to complying with applicable securities laws, the Holder must obtain
         the written consent of the Company prior to assigning this Note.

                  h. Time is of the essence of this Note and the performance of
         all provisions hereof.

                  i. This Note is registered on the books of the Company and is
         transferable only by surrender thereof at the principal office of the
         Company duly endorsed or accompanied by a written instrument of
         transfer duly executed by the registered Lender of this Note or his
         attorney duly authorized in writing. Payment of or on account of
         principal and interest on this Note shall be made only to or upon the
         order in writing of the registered Lender.

                  j. This Note is governed by and construed in accordance with
         the laws of the State of Delaware.

                  k. The Lender will not be entitled to vote, receive dividends
         or exercise any of the rights of the holders of the Company's equity
         securities for any purpose prior to the conversion of this Note.
