this Agreement or any applicable law (e.g., in the case of any breach or default

absolute. Both parties waive any right, either express or implied by applicable
law or otherwise, to renewal of this Agreement or to any damages or compensation
for any expiration or termination of the Term in accordance with this
Section 10. Each of the parties have considered the possibility of such
expiration or termination and the possibility of loss and damage resulting there
from in making expenditures pursuant to the performance of this Agreement. It is
the express intent and agreement of the parties that neither will be liable to
the other for damages or otherwise by reason of the expiration or termination of
the Term as provided for herein.

10.8Survival. Sections, 6, 7, 8, 10.4, 11, and 12.5-12.13 will survive
expiration or termination of this Agreement for any reason.

11.LIMITATION OF LIABILITY. HET'S AND MJC'S LIABILITY (WHETHER IN TORT, CONTRACT
OR OTHERWISE AND NOTWITHSTANDING ANY FAULT, NEGLIGENCE (WHETHER ACTIVE, PASSIVE
OR IMPUTED), PRODUCT LIABILITY, OR STRICT LIABILITY OF HET) UNDER THIS AGREEMENT
OR WITH REGARD TO ANY

11

--------------------------------------------------------------------------------

PRODUCTS OR OTHER ITEMS FURNISHED UNDER THIS AGREEMENT WILL IN NO EVENT EXCEED
THE COMPENSATION PAID (OR PAYABLE AS A RESULT OF THE TAKE-OR-PAY COMMITMENTS SET
FORTH IN EXHIBIT A HERETO) TO HET UNDER THIS AGREEMENT. IN NO EVENT WILL HET OR
MJC BE LIABLE FOR ANY INDIRECT, INCIDENTAL SPECIAL OR CONSEQUENTIAL DAMAGES
ARISING OUT OF ITS PERFORMANCE OR NONPERFORMANCE OF THIS AGREEMENT OR THE USE
OF, INABILITY TO USE, OR RESULTS OF USE OF ANY PRODUCTS. THIS SECTION SHALL NOT
APPLY TO LIABILITY FOR INDEMNIFICATION UNDER SECTION 8 OF THIS AGREEMENT.

12.  MISCELLANEOUS.

12.1Independent Contractor. Each of MJC and HET is an independent contractor and
not an agent, employee, franchise or partner of the other, and is acting in the
ordinary course of business. Neither HET nor MJC has any authority to, and will
not create or assume any obligation, express or implied, on behalf of the other.
HET and MJC shall each be responsible for all taxes and payments concerning
itself, its employees and its sales representatives. This Agreement does not
create or evidence any joint venture or partnership of the parties.

12.2Force Majeure. Neither party will be liable for, or be considered to be in
breach of or default under this Agreement on account of, any delay or failure to
perform as required by this Agreement (other than for payments owed) as a result
of any cause or condition beyond such party's reasonable control.

12.3Assignment. Neither HET nor MJC may assign or transfer, by operation of law
or otherwise, any of its rights under this Agreement or delegate any of its
duties under this Agreement to any third party other than its Affiliates without
the other party's prior written consent. Any attempted assignment or transfer in
violation of the foregoing will be void.

12.4Notice. Notices or consents under this Agreement will be in writing and
delivered personally or, if mailed, will be sent certified mail, return receipt
requested, or facsimile or overnight express service, if addressed to the
recipient's address set forth on the signature page of this Agreement, or in
either case to such other address as may be established by notice to the other
party. Notice will be effective only upon actual receipt.

12.5Nonwaiver. The failure of either party to insist upon or enforce strict
performance of any of the provisions of this Agreement or to exercise any rights
or remedies under this Agreement will not be construed as a waiver or
relinquishment to any extent of such party's right to assert or rely upon any
such provisions, rights or remedies in that or any other instance; rather, the
same will be and remain in full force and effect.

12.6Interpretation. The English language of the Agreement will govern any
interpretation of or dispute regarding the terms of this Agreement. Paragraph
captions are for convenience of reference and do not alter or limit the terms of
this Agreement.

12.7Remedies. Except as provided in Section 8 (Warranties, Remedies and
Disclaimers) the parties' rights and remedies under this Agreement are
cumulative. MJC acknowledges that the Products contain valuable trade secrets
and proprietary information of HET, that any actual or threatened breach of
Section 7.2 (Trademark License) or Section 6 (Confidentiality) will constitute
immediate, irreparable harm to HET for which monetary damages would be an
inadequate remedy, and that injunctive relief is an appropriate remedy for such
breach. If MJC continues to distribute the Products after its right to do so has
terminated or expired, HET will be entitled to immediate injunctive relief
without the requirement of posting bond, including an order directing that any
Products that MJC attempts to import into any country or territory be seized,
impounded, and destroyed by customs officials. If any legal action is brought to
enforce this Agreement, the prevailing party will be entitled to receive its
attorneys' fees, court costs, and other collection expenses, in addition to any
other relief it may receive.

12

--------------------------------------------------------------------------------

12.8     Severability. If any provision of this Agreement is unenforceable, such
provision will be changed and interpreted to accomplish the objectives of such
provision to the greatest extent possible under applicable law and the remaining
provisions will continue in full force and effect. Without limiting the
generality of the foregoing, MJC agrees that Section 11 (Limitation of
Liability) will remain in effect notwithstanding the unenforceability of any
provision in Section 8 (Warranties, Remedies and Disclaimers).
12.9  
 
Construction. As used in this Agreement, the word "including" means "including
but not limited to."
12.10
 
Counterparts. This Agreement may be executed in counterparts, each of which will
be considered an original, but all of which together will constitute the same
instrument.
12.11
 
Arbitration. The parties agree to make every reasonable effort to amicably
settle any controversy between them relating to the terms and conditions and
subject matter of this Agreement. In the event that the parties are unable to
reach an amicable settlement regarding any controversy relating to the terms,
conditions or subject matter of this Agreement, the parties agree that, within
30 days following written notice of a request for arbitration served by one of
the parties upon the other, they shall submit such controversy to a single,
independent, unbiased arbitrator. The arbitration will be carried out in accord
with the rules of the American Arbitration Association at its offices in
Chicago, Illinois. Discovery will be carried out in accord with the Federal
Rules of Civil Procedure and, should said rules be in conflict with any of the
rules of the American Arbitration Association, the Federal Rules shall prevail.
In the event the parties cannot agree upon a single arbitrator within 20 days
following a written request for arbitration, the arbitrator will be selected by
the American Arbitration Association. The decision of the arbitrator will be
final and binding upon both parties. Upon application by either party, the
decision of the arbitrator may be entered as a final award or judgment by any
court of competent jurisdiction in the United States of America.
12.12
 
Governing Law; Venue. The rights and obligations of the parties under this
agreement shall be governed in all respects by the laws of the State of Colorado
exclusively; as such laws apply to contracts between Colorado residents
performed entirely within Colorado. MJC agrees that upon HET's request, all
disputes arising hereunder shall be adjudicated in the state and federal courts
having jurisdiction over disputes arising in Denver, Colorado, and MJC hereby
agrees to consent to the personal jurisdiction of such courts.
12.13
 
Entire Agreement. This Agreement contains the entire agreement, and supersedes
any and all prior agreements, between the parties with regard to the appointment
of MJC as a distributor of Products and MJC's purchase and sale of Products. HET
will not be bound be, and specifically objects to, any terms, conditions, or
other provisions that are different from or in addition to the provisions of the
Agreement (whether or not it would materially alter this correspondence, or
otherwise. Without limiting the generality of the foregoing, any printed terms,
conditions of other provisions that are included in or accompany any of the
MJC's orders for Products under this Agreement will not apply to be binding on
HET. This Agreement may not be waived, amended or rescinded except by a writing
signed by the party to be charged thereby.
12.14

or the relationship between the parties unless the release is approved in
advance by the other party in writing.

Attention:   Randall K. Alsman
President, U.S. and Global Business Support

Re:
 
Amendment to Strategic Partnership Agreement between Mead Johnson & Company
("MJC") and HealtheTech, Inc. ("HET") dated as of August 8, 2002 (the
"Agreement").

Dear Mr. Alsman:

        This letter will amend the Agreement as specified below. All capitalized
terms used and not defined in this letter shall have the meanings assigned to
them in the Agreement. The Agreement shall continue to be binding except to the
extent modified herein.

        As we have discussed, although the Agreement provides that MJC shall
have the exclusive right, beginning October 1, 2002, to sell HET Products in the
Exclusive Markets, MJC will not be in a position to market or sell the Products
until members of its sales force have been trained to sell the Products. The
parties currently anticipate that this training will be completed no later than
January 10, 2003 and will be confirmed by written notice from MJC to HET on the
date of such completion (the "Product Launch Date").

        Accordingly, MJC and HET have agreed as follows:

1.Until the Product Launch Date, HET may sell Products in the Exclusive Markets.
These sales will be solicited and made directly by HET and not through any other
person or entity. Within 10 business days after each of October 31, November 30,
December 31 and the end of each subsequent month until the Product Launch Date,
HET shall send MJC a written report of all sales of Products in the Exclusive
Markets during the period since the previous report. Each report will include,
for each sale, the institution/customer name, full address, key contact, date of
sale, any customer service comments, and number of each Product sold.

2.Any sales by HET of MedGem Devices and Breathing Inserts in the Exclusive
Markets from October 1, 2002 through the Product Launch Date shall reduce, on a
one-for-one basis, MJC's Take-or-Pay Purchase Commitments for Q1 2003 as set
forth in Exhibit B to the Agreement.

3.As soon as practicable after the Product Launch Date, HET and MJC will
cooperate to ensure an orderly transition from HET to MJC of all accounts
generated by HET in the Exclusive Markets pursuant to this letter.

4.MJC hereby waives, until the Product Launch Date, HET's obligation (in
Section 3.4(a) of the Agreement) to refer to MJC all inquiries for purchase of
Products received from within the Markets and Territories. However, HET will
provide to MJC by January 1, 2003 relevant information on all inquiries and
leads up to that date, and HET will supplement that information as of the
Product Launch Date.

--------------------------------------------------------------------------------

5.For the purpose of this Amendment, a sale will be treated as occurring on the
date the Product is shipped to the customer. HET shall not make any statement to
any prospective customer in the Exclusive Markets that may lead that party to
believe that it may be able to purchase Products after the Product Launch Date
for less than [***] dollars ($[***]) for a device or [***] dollars ($[***]) for
an insert.

        Please indicate your agreement to the terms of this letter by executing
where indicated below and returning a copy to us.

    Very truly yours,
