Warrant to Purchase
76,000 Shares of
Common Stock of the Company
(subject to adjustment)

THIS CERTIFIES THAT, for value received, Xxxxx X. Xxxxxx (the "Holder") is entitled, subject to the terms and conditions set forth below, to purchase from HealtheTech, Inc., a Delaware corporation (the "Company"), up to seventy-six thousand (76,000) shares of the Company's Common Stock, $0.001 par value per share (the "Shares"), subject to the provisions and upon the terms and conditions set forth herein. The term "Warrant" as used herein shall include this Warrant and any warrants delivered in substitution or exchange therefore as provided herein. This Warrant is issued in consideration for certain consulting services to be provided by the Holder to the Company pursuant to the terms and conditions of a letter agreement, dated as of September 27, 2002, by and between the Company and the Holder.

1. Number, Price and Expiration of the Shares.

(a) Two Year Right to Purchase the Shares. The Holder shall have the right to purchase up to a total of forty thousand (40,000) of the Shares (as may be adjusted pursuant hereto), at an exercise price of $7.50 per share, which right shall terminate, to the extent not exercised, at 5:00 p.m., Mountain Time, on September 26, 2004.

(b) Three Year Right to Purchase the Shares. The Holder shall have the right to purchase up to a total of thirty-six thousand (36,000) of the Shares (as may be adjusted pursuant hereto), at an exercise price of $10.00 per share, which right shall terminate, to the extent not exercised, at 5:00 p.m., Mountain Time, on September 26, 2005.

2. Exercise of Warrant.

(a) Exercise. The purchase rights represented by this Warrant may be exercised at the election of the Holder, in whole or in part, in accordance with Section 1 and prior to the expiration of this Warrant, by (i) the tender to the Company at its principal office (or such other office or agency of the Company as it may designate by notice in writing to the Holder at the address of the Holder appearing on the books of the Company) of a notice of exercise in the form attached hereto as Exhibit A (the "Notice of Exercise"), duly completed and executed on behalf of the Holder, together with the surrender of this Warrant, and (ii) the payment to the Company of an amount equal to the applicable exercise price(s) multiplied by

the number of Shares being purchased by wire transfer or certified, cashier's or other check acceptable to the Company and payable to the order of the Company.

(b) Stock Certificates. The rights under this Warrant shall be deemed to have been exercised and the Shares shall be deemed to have been issued immediately prior to the close of business on the date of its tender for exercise as provided above, and the person entitled to receive the Shares issuable upon such exercise shall be treated for all purposes as the holder of record of such Shares as of the close of business on such date. As promptly as reasonably practicable on or after such date, the Company shall direct the Company's transfer agent to issue and deliver to the person or persons entitled to receive the same a certificate or certificates for that number of shares issuable upon such exercise. In the event that the rights under this Warrant are exercised in part and have not expired, the Company shall execute and deliver a new Warrant with the same terms and conditions for the number of Shares that remain subject to this Warrant.

(c) Taxes. In no event shall the Company be required to pay any tax which may be payable in respect of any transfer involved in the issue and delivery of any certificate in a name other than that of the Holder, and the Company shall not be required to direct the Company's transfer agent to issue or deliver any such certificate unless and until the person or persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid.

3. No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of the rights under this Warrant. In lieu of such fractional share to which the Holder would otherwise be entitled, the Company shall make a cash payment equal to the applicable exercise price(s) multiplied by such fraction.

4. Replacement of Warrant. On receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and, in the case of loss, theft or destruction, on delivery of an indemnity agreement reasonably satisfactory in form and substance to the Company or, in the case of mutilation, on surrender and cancellation of this Warrant, the Company at the expense of the Holder shall execute and deliver, in lieu of this Warrant, a new warrant of like tenor and amount.

5. Piggy-back Registration Rights.

The Shares issued upon exercise of this Warrant shall have certain piggy-back registration rights as set forth in Attachment A.

6. Representations and Warranties of the Holder.

(a) Investment Intent. The Holder is acquiring the Securities Warrant and the Shares issuable upon exercise of the Warrant, for investment for his own account, not as a nominee or agent, and not with the view to, or for resale in connection with, any distribution thereof.

(b) Investment Experience. The Holder has substantial experience in evaluating and investing in private placement transactions of securities in companies similar to the Company so that he is capable of evaluating the merits and risks of his investment in the Company and has the capacity to protect his own interests.

(c) Speculative Nature of Investment. The Holder acknowledges that his investment in the Company is highly speculative and entails a substantial degree of risk and the Holder is in a position to lose the entire amount of such investment.

(d) Access to Data. The Holder has had an opportunity to discuss the Company's business, management and financial affairs with the Company's management. The Holder has also had an opportunity to ask questions of officers of the Company, which questions were

answered to his satisfaction. The Holder understands that such discussions, as well as any information issued by the Company, were intended to describe certain aspects of the Company's business and prospects, but were not necessarily a thorough or exhaustive description. The Holder acknowledges that any business plans prepared by the Company have been, and continue to be, subject to change and that any projections included in such business plans or otherwise are necessarily speculative in nature, and it can be expected that some or all of the assumptions underlying the projections will not materialize or will vary significantly from actual results.

(e) Accredited Investor. The Holder is an "accredited investor" within the meaning of Regulation D, Rule 501(a), promulgated by the Securities and Exchange Commission under the Securities Act of 1933, as amended (the "Securities Act").

(f) Residency. The residency of the Holder is correctly set forth on the signature page hereto.

(g) Restriction on Resales. The Holder acknowledges that the Securities Warrant and the Shares issuable upon exercise of the Warrant must be held indefinitely unless subsequently registered under the Securities Act or unless an exemption from such registration is available. The Holder further understands that there is no assurance that any exemption from registration under the Securities Act will be available or, if available, that such exemption will allow the Holder to dispose of or otherwise transfer any or all of the Securities under the circumstances, in the amounts or at the times the Holder might propose.

(h) Rule 144. The Holder is aware of the provisions of Rule 144 promulgated under the Securities Act which permit limited resale of shares purchased in a private placement subject to the satisfaction of certain conditions, including among other things, the existence of a public market for the shares, the availability of certain current public information about the Company, the resale occurring not less than one year after a party has purchased and paid for the security to be sold, the sale being effected through a "broker's transaction" or in transactions directly with a "market maker" and the number of shares being sold during any three-month period not exceeding specified limitations. The Holder acknowledges that, in the event all of the requirements of Rule 144 are not met, registration under the Securities Act or an exemption from registration will be required for any disposition of the Securities. The Holder understands that, although Rule 144 is not exclusive, the Securities and Exchange Commission has expressed its opinion that persons proposing to sell restricted securities received in a private offering other than in a registered offering or pursuant to Rule 144 will have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales and that such persons and the brokers who participate in the transactions do so at their own risk.

(i) Authorization.

(i) The Holder has all requisite power and authority to execute and deliver this Warrant, to purchase the Shares issuable upon exercise of the rights under this Warrant and to carry out and perform his obligations under the terms and conditions of this Warrant. All action on the part of the Holder necessary for the authorization, execution, delivery and performance of this Warrant, and the performance of all of the Holder's obligations under this Warrant, has been taken or will be taken prior to the purchase of this Warrant.

(ii) This Warrant, when executed and delivered by the Holder, will constitute a valid and legally binding obligation of the Holder, enforceable in accordance with its terms except: (i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium

and other laws of general application affecting enforcement of creditors' rights generally, and (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies or by general principles of equity.

(iii) No consent, approval, authorization, order, filing, registration or qualification of or with any court, governmental authority or third person is required to be obtained by the Holder in connection with the execution and delivery of this Warrant or the performance of the Holder's obligations hereunder.

(j) Brokers and Finders. The Holder has not engaged any brokers, finders or agents in connection with this Warrant, and the Company has not incurred and will not incur, directly or indirectly, as a result of any action taken by the Holder, any liability for brokerage or finders' fees or agents' commissions or any similar charges in connection with this Warrant.

(k) Investor Counsel. The Holder acknowledges that he has had the opportunity to review this Warrant and the exhibits attached hereto and the transactions contemplated by this Warrant with his own legal counsel. The Holder is relying solely on such counsel and not on any statements or representations of the Company or its agents for legal advice with respect to this investment or the transactions contemplated by this Warrant.

(l) Tax Advisors. The Holder has reviewed with his own tax advisors the U.S. federal, state, local and foreign tax consequences of this investment and the transactions contemplated by this Warrant. With respect to such matters, the Holder relies solely on such advisors and not on any statements or representations of the Company or any of its agents, written or oral. The Holder understands that he (and not the Company) shall be responsible for his own tax liability that may arise as a result of this investment or the transactions contemplated by this Warrant.

7. Transfer of Warrants; Restrictions on Transfer.

(a) Warrant Register. The Company shall maintain a register (the "Warrant Register") containing the name and address of the Holder or Holders. Any Holder of this Warrant or any portion thereof may change its address as shown on the Warrant Register by written notice to the Company requesting such change. Any written notice or written communication required or permitted to be given to the Holder may be delivered or given by any method provided in Section 12(d) hereof. Until this Warrant is transferred on the Warrant Register, the Company may treat the Holder as shown on the Warrant Register as the absolute owner of this Warrant for all purposes, notwithstanding any notice to the contrary.

(b) Warrant Agent. The Company may, by notice to the Holder, appoint an agent for the purpose of maintaining the Warrant Register referred to in Section 7(a) above, issuing the Shares or other securities then issuable upon the exercise of the rights under this Warrant, exchanging this Warrant, replacing this Warrant or any or all of the foregoing. Thereafter, any such registration, issuance, exchange or replacement, as the case may be, shall be made at the office of such agent.

(c) Transferability and Non-negotiability of Warrant. This Warrant may not be transferred or assigned in whole or in part without compliance with all applicable federal and state securities laws by the transferor and the transferee. Subject to the provisions of this Warrant with respect to compliance with the Securities Act and limitations on assignments and transfers, including without limitation compliance with the restrictions on transfer set forth in Section 7(e) hereof, title to this Warrant may be transferred by endorsement (by the transferor and the transferee executing the assignment form (the "Assignment Form") attached hereto as Exhibit C) and delivery in the same manner as a negotiable instrument transferable by endorsement and delivery.

(d) Exchange of Warrant upon a Transfer. On surrender of this Warrant for exchange and a properly endorsed Assignment Form, and subject to the provisions of this Warrant with respect to compliance with the Securities Act and limitations on assignments and transfers, the Company shall issue to or on the order of the Holder a new warrant or warrants with the same terms and conditions, in the name of the Holder or such other individual or entity as the Holder (on payment by the Holder of any applicable transfer taxes) may direct, for the number of shares Shares issuable upon exercise of the rights hereunder and the Company shall register any such transfer upon the Warrant Register. This Warrant and the Shares issuable upon exercise of the rights under this Warrant must be surrendered to the Company or its warrant or transfer agent, as applicable, as a condition precedent to the sale, pledge, hypothecation or any other transfer of any interest in any of the securities represented hereby. Upon the transfer of this Warrant pursuant to the terms of this Section 7, the transferee shall be a "Holder" under the terms hereof.

(e) Restrictions on Transfer of Warrants and Shares; Compliance with Securities Laws.

(i) The Holder agrees not to make any disposition of all or any portion of the Shares or this Warrant unless and until, and it shall be a condition to the transfer of all or any portion of the Shares or this Warrant that: (1) there is then in effect a registration statement under the Securities Act covering such proposed disposition and such disposition is made in accordance with such registration statement or (2) (A) the Holder shall have notified the Company of the proposed disposition and shall have furnished the Company with a detailed statement of the circumstances surrounding the proposed disposition, (B) the transferee shall have agreed in writing to be bound by and subject to the terms, conditions, restrictions, obligations and other limitations set forth in this Warrant to the same extent as if such transferee were the original Holder hereunder, (C) the transferee shall have confirmed to the satisfaction of the Company in writing, substantially in the form attached hereto as Exhibit B, that the Shares or the Warrant purchased are being acquired solely for the transferee's own account and not as a nominee for any other party, for investment and not with a view toward distribution or resale and that the transferee shall have confirmed such other matters related thereto as may be reasonably requested by the Company, and (D) if requested by the Company, the Holder shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, that such disposition will not require registration of the Warrant or such Shares under the Securities Act. This Warrant or any portion hereof and any Shares issuable pursuant to the exercise of the rights under this Warrant that are transferred to a transferee shall be subject to the terms, conditions, restrictions, obligations and other limitations set forth herein.

(ii) Unless the rights under this Warrant are exercised pursuant to an effective registration statement under the Securities Act that includes the Shares with respect to which the Warrant was exercised, it shall be a condition to any exercise of the rights under this Warrant that the Holder shall have confirmed to the satisfaction of the Company in writing, substantially in the form attached hereto as Exhibit B, that the Shares so purchased are being acquired solely for the Holder's own account and not as a nominee for any other party, for investment and not with a view toward distribution or resale and that the Holder shall have confirmed such other matters related thereto as may be reasonably requested by the Company.

(iii) This Warrant and all Shares issued upon exercise hereof shall be stamped or imprinted with a legend in substantially the following form (in addition to any legend required by state securities laws):

"THESE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT FOR DISTRIBUTION, AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. SUCH SECURITIES MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED IN THE ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH RESPECT THERETO UNDER SUCH ACT UNLESS SOLD PURSUANT TO RULE 144 OF SUCH ACT OR UNLESS SUCH SALE, OFFER, PLEDGE, HYPOTHECATION OR TRANSFER IS OTHERWISE EXEMPT FROM REGISTRATION."

(f) This Warrant may not be transferred in part unless such transfer is to a transferee who, pursuant to such transfer, receives the right to purchase at least five thousand (5,000) Shares hereunder (as adjusted from time to time in accordance with Section 10 hereof).

8. Reservation of Stock. The Company agrees during the term the rights under this Warrant are exercisable to reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance of the Shares upon the exercise of the rights under this Warrant and, from time to time, to use its best efforts to amend its Certificate of Incorporation to provide sufficient reserves of shares of Common Stock issuable upon exercise of the rights under the Warrant.

9. Expiration; Early Termination. This Warrant shall expire on September 26, 2005, and shall be void thereafter. Notwithstanding the foregoing, this Warrant shall terminate immediately prior to the voluntary liquidation, dissolution or winding up of the Company.

10. Adjustment Rights. The number and kind of shares purchasable hereunder and the applicable exercise price(s) therefore are subject to adjustment from time to time, as follows:

(a) Merger. The number and kind of shares If at any time after the date hereof there shall be any reorganization, recapitalization, merger or consolidation involving the Company in which shares of the Company's stock (other than a reorganization, recapitalization, merger or consolidation or a related combination, reclassification, exchange, capital reorganization, subdivision of securities or other transaction otherwise provided for herein) are converted into or exchanged for securities, cash or other property, other than as would cause the expiration of this Warrant, then, as a part of such reorganization, recapitalization, merger or consolidation, lawful provision shall be made so that the Holder shall thereafter be entitled to receive upon exercise of his rights to purchase the Shares hereunder, the kind and amount of securities, cash or other property of the successor corporation resulting from such reorganization, recapitalization, merger or consolidation, equivalent in value to that which a holder of the Common Stock deliverable upon exercise of such rights to purchase the Shares hereunder would have been entitled in such reorganization, recapitalization, merger or consolidation if such rights to purchase the Shares hereunder had been exercised immediately prior to such reorganization, recapitalization, merger or consolidation. In any such case, appropriate adjustment (as determined in good faith by the Company's Board of Directors) shall be made in the application of the provisions of this Warrant with respect to the rights and interests of the Holder after such reorganization, recapitalization, merger or consolidation to the end that the provisions of this Warrant (including adjustments of the applicable exercise price(s) and number of shares of Common Stock purchasable pursuant to the terms and conditions of this Warrant) shall be applicable after the event, as near as reasonably may be, in relation to any shares or other securities deliverable after that event upon the exercise of the Holder's rights to purchase the Shares pursuant to this Warrant.

(b) Reclassification of Shares. If the Company at any time after the date hereof shall, by combination, reclassification, exchange, capital reorganization or subdivision of securities or otherwise (other than a combination, reclassification, exchange, capital reorganization or subdivision of securities or a related reorganization, recapitalization, merger, consolidation or other transaction otherwise provided for herein), change any of the securities as to which purchase rights under this Warrant exist into the same or a different number of securities of any other class or classes, this Warrant shall thereafter provide for the right or rights to acquire such number and kind of securities as would have been issuable as the result of such change with respect to the securities which were subject to the purchase rights under this Warrant immediately prior to such combination, reclassification, exchange, capital reorganization, subdivision or other change. In any such case, appropriate adjustment (as determined in good faith by the Company's Board of Directors) shall be made in the application of the provisions of this Warrant with respect to the rights and interests of the Holder after such combination, reclassification, capital reorganization, exchange, subdivision or change to the end that the provisions of this Warrant (including adjustments of the applicable exercise price(s) and number of shares of Common Stock purchasable pursuant to the terms and conditions of this Warrant) shall be applicable after the event, as near as reasonably may be, in relation to any shares or other securities deliverable after that event upon the exercise of the Holder's rights to purchase the Shares pursuant to this Warrant.

(c) Subdivisions and Combinations. In the event that the Company shall at any time subdivide (by stock split, by payment of a stock dividend or otherwise) the outstanding shares of Common Stock, the number of Shares issuable upon exercise of the rights under this Warrant immediately prior to such subdivision shall, concurrently with the effectiveness of such subdivision, be proportionately increased, and the applicable exercise price(s) shall be proportionately decreased, and in the event that the Company shall at any time combine (by reclassification or otherwise) the outstanding shares of Common Stock into a lesser number of shares of Common Stock, the number of Shares issuable upon exercise of the rights under this Warrant immediately prior to such combination shall, concurrently with the effectiveness of such combination, be proportionately decreased, and the applicable exercise price(s) shall be proportionately increased.

(d) Notice of Adjustments. Upon any adjustment of any of the exercise prices or any increase or decrease in the number of Shares purchasable upon the exercise of the rights under this Warrant in accordance with this Section 10, then, and in each such case, the Company, within thirty (30) days thereafter, shall promptly give notice thereof, to the Holder at the address of such Holder as shown on the Warrant Register of the Company, delivered by any method provided in Section 12(d) hereof, which notice shall state the event giving rise to the adjustment, the exercise price(s) as adjusted and, if applicable, the increased or decreased number of Shares purchasable upon the exercise of the rights under this Warrant, setting forth in reasonable detail the method of calculation of each.

(e) Other Notices. In the event that the Company shall authorize: (1) the issuance of any dividend or other distribution on the Common Stock (other than: (i) repurchases of Common Stock issued to or held by employees, officers, directors or consultants of the Company or its subsidiaries upon termination of their employment or services pursuant to agreements providing for the right of said repurchase; (ii) repurchases of Common Stock issued to or held by employees, officers, directors or consultants of the Company or its subsidiaries pursuant to rights of first refusal contained in agreements providing for such right; or (iii) repurchases of capital stock of the Company in connection with the settlement of disputes with any stockholder), whether in cash, property, stock or other securities; (2) the voluntary liquidation, dissolution or winding up of the Company; or (3) any transaction

resulting in the expiration of this Warrant; then, in each such case, the Company shall give written notice thereof to the Holder at the address of such Holder as shown on the Warrant Register of the Company, delivered by any method provided in Section 12(d) hereof, at least five (5) days prior to the effective date of such event. The notice provisions set forth in this section may be shortened or waived prospectively or retrospectively by the vote or written consent of the holders of a majority of the Shares issuable upon exercise of the rights under this Warrant.

11. No Rights as Stockholder. Nothing contained herein shall entitle the Holder to any rights as a stockholder of the Company or to be deemed the holder of Common Stock or any other securities that may at any time be issuable on the exercise of the rights hereunder for any purpose nor shall anything contained herein be construed to confer upon the Holder, as such, any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action (whether upon any recapitalization, issuance of stock, reclassification of stock, change of par value or change of stock to no par value, consolidation, merger, conveyance or otherwise) or to receive notice of meetings, or to receive dividends or subscription rights or otherwise or any other rights of a stockholder of the Company until the rights under the Warrant shall have been exercised and the Shares purchasable upon exercise of the rights hereunder shall have become deliverable as provided herein.

12. Miscellaneous.

(a) Effective Date. The provisions of this Warrant shall be construed and shall be given effect in all respects as if it had been executed and delivered by the Company on the date hereof.

Any attempt by a party without such permission to assign, transfer, delegate or sublicense any rights, duties or obligations that arise under this Warrant shall be void.

ATTACHMENT A
PIGGY-BACK REGISTRATION RIGHTS

1. Company Registration.

(a) Registration. If at any time or from time to time, the Company shall determine to register any of its securities for its own account, other than (i) a registration on Form S-8 (or a similar or successor form) relating solely to employee stock option, stock purchase or other benefit plans, or (ii) a registration on Form S-4 (or similar or successor form) relating solely to a Securities and Exchange Commission (the "Commission") Rule 145 transaction, the Company will:

(i) promptly give to the holder of the Shares or any permitted transferee (as provided in Section 7 of the Warrant) (the "Holder") written notice thereof; and

(ii) offer to include in such registration (and any related qualification under blue sky laws or other compliance), and in any underwriting involved therein, all the Shares specified in a written request or requests, made within 15 days after mailing of written notice by the Company.

(b) Underwriting. If the registration of which the Company gives notice is for a registered public offering involving an underwriting, the Company shall so advise the Holder as a part of the written notice given pursuant to Section 1(a) (i) above. In such event the right of the Holder to registration pursuant to this section shall be conditioned upon such Holder's participation in such underwriting and the inclusion of such Shares in the underwriting to the extent provided herein.

The Holder proposing to distribute the Shares through such underwriting shall (together with the Company and, if applicable, any other holders distributing their securities through such underwriting) enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by the Company. Notwithstanding any other provision of this section, if the managing underwriter determines that marketing factors require a limitation of the number of shares to be underwritten, the underwriter may limit the number or exclude all of the Shares to be included in the registration and underwriting. The number of securities includable by the Holder may, in the discretion of the underwriters, be rounded to the nearest one hundred shares. No securities excluded from the underwriting by reason of the underwriter's marketing limitation shall be included in such registration. If some but not all of the Shares are to be excluded from a registration, the Shares to be included in the registration shall be allocated on a pro rata basis based on the total number of shares of all securities being included in such registration.; provided, that, no Registrable Securities, as that term is defined in that certain Sixth Amended and Restated Investor Rights Agreement, dated as of June 21, 2001, as amended, shall be excluded from any Company registration until all of the Shares have been excluded from such underwriting.

If the Holder disapproves of the terms of any such underwriting, the Holder may elect to withdraw therefrom by written notice to the Company and the underwriter. Any securities excluded or withdrawn from such underwriting shall be withdrawn from such registration.

If the underwriter has not limited the number of such shares to be underwritten for the Company's account and the account of the Holder, the Company may then include securities for the account of employees, officers, directors and consultants.

(c) Right to Terminate Registration. The Company shall have the right to terminate or withdraw any registration initiated by it under this Section 1(c) prior to the effectiveness of such registration whether or not the Holder has elected to include the Shares in such registration.

2. Registration Procedures. In the case of each registration, qualification or compliance effected by the Company pursuant to this section, the Company will keep the Holder advised in writing as to

Attachment A—Page 1

the initiation of each registration, qualification and compliance and as to the completion thereof. At its expense the Company will:

(a) Prepare and file with the SEC a registration statement with respect to such securities and use reasonable efforts to cause such registration statement to become and remain effective for at least 180 days or until the Holder have completed the distribution described in the registration statement relating thereto, whichever first occurs; and

(b) Furnish to the Holder participating in the registration such number of prospectuses, preliminary prospectuses, final prospectuses and such other documents as the Holder may reasonably request in order to facilitate the public sale or other disposition of the Shares being sold by the Holder.

3. Information by Holder. If any of the Shares are included in any registration, the Holder shall furnish to the Company such information regarding the Holder and the distribution proposed by the Holder as the Company may reasonably request in writing and as shall be required in connection with any registration, qualification or compliance referred to in this section.

4. Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission which may at any time permit the sale of the Shares to the public without registration, the Company agrees to use all reasonable efforts to:

INVESTMENT REPRESENTATION STATEMENT

HOLDER:
COMPANY:		HEALTHETECH, INC.
SECURITIES:		THE WARRANT (THE "WARRANT") TO PURCHASE SHARES OF COMMON STOCK (THE "WARRANT") ISSUED ON SEPTEMBER 27, 2002 AND THE COMMON STOCK ISSUED OR ISSUABLE UPON EXERCISE THEREOF
AMOUNT:		SHARES
DATE:		,

In connection with the purchase of the above-listed Securities, the undersigned Holder represents and warrants to, and agrees with, the Company as follows:

1. Investment Intent. The Holder is acquiring the Securities for investment for his own account, not as a nominee or agent, and not with the view to, or for resale in connection with, any distribution thereof.

2. Investment Experience. The Holder has substantial experience in evaluating and investing in private placement transactions of securities in companies similar to the Company so that he is capable of evaluating the merits and risks of his investment in the Company and has the capacity to protect his own interests.

3. Speculative Nature of Investment. The Holder acknowledges that his investment in the Company is highly speculative and entails a substantial degree of risk and the Holder is in a position to lose the entire amount of such investment.

4. Access to Data. The Holder has had an opportunity to discuss the Company's business, management and financial affairs with the Company's management. The Holder has also had an opportunity to ask questions of officers of the Company, which questions were answered to its satisfaction. The Holder understands that such discussions, as well as any information issued by the Company, were intended to describe certain aspects of the Company's business and prospects, but were not necessarily a thorough or exhaustive description. The Holder acknowledges that any business plans prepared by the Company have been, and continue to be, subject to change and that any projections included in such business plans or otherwise are necessarily speculative in nature, and he can be expected that some or all of the assumptions underlying the projections will not materialize or will vary significantly from actual results.

5. Accredited Investor. The Holder is an "accredited investor" within the meaning of Regulation D, Rule 501(a), promulgated by the Securities and Exchange Commission under the Securities Act of 1933, as amended (the "Securities Act").

6. Residency. The residency of the Holder (or, in the case of a partnership or corporation, such entity's principal place of business) is correctly set forth on the signature page hereto.

7. Restriction on Resales. The Holder acknowledges that the Securities must be held indefinitely unless subsequently registered under the Securities Act or unless an exemption from such registration is available. The Holder further understands that there is no assurance that any exemption from registration under the Securities Act will be available or, if available, that such exemption will allow the Holder to dispose of or otherwise transfer any or all of the Securities under the circumstances, in the amounts or at the times the Holder might propose.

8. Rule 144. The Holder is aware of the provisions of Rule 144 promulgated under the Securities Act which permit limited resale of shares purchased in a private placement subject to the satisfaction of certain conditions, including among other things, the existence of a public market for the

Exhibit B—Page 1

shares, the availability of certain current public information about the Company, the resale occurring not less than one year after a party has purchased and paid for the security to be sold, the sale being effected through a "broker's transaction" or in transactions directly with a "market maker" and the number of shares being sold during any three-month period not exceeding specified limitations. The Holder acknowledges that, in the event all of the requirements of Rule 144 are not met, registration under the Securities Act or an exemption from registration will be required for any disposition of the Securities. The Holder understands that, although Rule 144 is not exclusive, the Securities and Exchange Commission has expressed its opinion that persons proposing to sell restricted securities received in a private offering other than in a registered offering or pursuant to Rule 144 will have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales and that such persons and the brokers who participate in the transactions do so at their own risk.

9. Authorization. The Holder has all requisite power and authority to execute and deliver the Warrant, to purchase the Securities and to carry out and perform its obligations under the terms of the Warrant. All action on the part of the Holder necessary for the authorization, execution, delivery and performance of the Warrant, and the performance of all of the Holder's obligations under the Warrant, has been taken or will be taken prior to the purchase of the Warrant.

(b) The Warrant, when executed and delivered by the Holder, will constitute a valid and legally binding obligation of the Holder, enforceable in accordance with its terms except: (i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors' rights generally, and (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies or by general principles of equity.

(c) No consent, approval, authorization, order, filing, registration or qualification of or with any court, governmental authority or third person is required to be obtained by the Holder in connection with the execution and delivery of the Warrant or the performance of the Holder's obligations hereunder.

10. Brokers or Finders. The Holder has not engaged any brokers, finders or agents, and the Company has not incurred and will not incur, directly or indirectly, as a result of any action taken by the Holder, any liability for brokerage or finders' fees or agents' commissions or any similar charges in connection with the Warrant.

11. Investor Counsel. The Holder acknowledges that he has had the opportunity to review the Warrant and the exhibits attached thereto and the transactions contemplated by the Warrant with his own legal counsel. The Holder is relying solely on such counsel and not on any statements or representations of the Company or its agents for legal advice with respect to this investment or the transactions contemplated by the Warrant.

12. Tax Advisors. The Holder has reviewed with his own tax advisors the U.S. federal, state, local and foreign tax consequences of this investment and the transactions contemplated by the Warrant. With respect to such matters, the Holder relies solely on such advisors and not on any statements or representations of the Company or any of its agents, written or oral. The Holder understands that it (and not the Company) shall be responsible for his own tax liability that may arise as a result of this investment or the transactions contemplated by the Warrant.

13. Further Limitations on Disposition. Without in any way limiting the representations and warranties set forth above, the Holder agrees not to make any disposition of all or any portion of the Securities unless and until, and it shall be a condition to the transfer of all or any portion of the Securities that: (1) there is then in effect a registration statement under the Securities Act covering such proposed disposition and such disposition is made in accordance with such registration statement

Exhibit B—Page 2

or (2) (A) the Holder shall have notified the Company of the proposed disposition and shall have furnished the Company with a detailed statement of the circumstances surrounding the proposed disposition, (B) the transferee shall have agreed in writing to be bound by and subject to the terms, conditions, restrictions, obligations and other limitations set forth in the Warrant to the same extent as if such transferee were the original Holder thereunder, (C) the transferee shall have confirmed to the satisfaction of the Company in writing, substantially in the form attached to the Warrant as Exhibit B, that the Securities are being acquired solely for the transferee's own account and not as a nominee for any other party, for investment and not with a view toward distribution or resale and that the transferee shall have confirmed such other matters related thereto as may be reasonably requested by the Company, and (D) if requested by the Company, the Holder shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, that such disposition will not require registration of the Securities under the Securities Act. The Securities that are transferred to a transferee shall be subject to the terms, conditions, restrictions, obligations and other limitations set forth herein and therein.

(The remainder of this page is intentionally left blank.)
