"SECURITIES ACT") OR ANY STATE SECURITIES LAWS AND MAY NOT BE SOLD, TRANSFERRED
OR OTHERWISE DISPOSED OF UNLESS REGISTERED UNDER THE SECURITIES ACT AND UNDER

                               WARRANT TO PURCHASE

                             SHARES OF COMMON STOCK

                                       OF

                               NUTRITION 21, INC.

Date of Issuance: May __, 2006

      FOR VALUE RECEIVED, subject to the provisions hereinafter set forth, the
undersigned, NUTRITION 21, INC., a New York corporation (together with its
successors and assigns, the "Issuer"), hereby certifies that CD Investment
Partners, Ltd. or its registered assigns (the "Holder") is entitled to subscribe
for and purchase, during the Term (as hereinafter defined), up to
____________________________________ (_____________) shares (subject to
adjustment as hereinafter provided) of the duly authorized, validly issued,
fully paid and non-assessable Common Stock of the Issuer, at an exercise price
per share equal to the Warrant Price then in effect on the terms and conditions
hereinafter set forth. Capitalized terms used in this Warrant and not otherwise
defined herein shall have the respective meanings specified in Section 8 hereof.

      1. Term. The term of this Warrant shall commence on May __, 2006 and shall
expire at 6:00 p.m., eastern time, on May __, 2011 (such period being the
"Term").

      2. Method of Exercise; Payment; Issuance of New Warrant; Transfer and
Exchange.

      (a) Time of Exercise. The purchase rights represented by this Warrant may
be exercised from time to time in whole or in part during the Term.

<PAGE>

      (b) Method of Exercise. The Holder hereof may exercise this Warrant, in
whole or in part, by the surrender of this Warrant (with the exercise form
attached hereto as Exhibit A duly executed) at the principal office of the
Issuer, and by the payment to the Issuer of an amount of consideration therefor
equal to the Warrant Price in effect on the date of such exercise multiplied by
the number of shares of Warrant Stock with respect to which this Warrant is then
being exercised, payable at such Holder's election (i) by certified or official
bank check or by wire transfer to an account designated by the Issuer, (ii) by
"cashless exercise" in accordance with the provisions of subsection (c) of this
Section 2, but only when a registration statement under the Securities Act
providing for the resale of the Warrant Stock is not then in effect, or (iii) by
a combination of the foregoing methods of payment selected by the Holder of this
Warrant.

      (c) Cashless Exercise. Notwithstanding any provisions herein to the
contrary and commencing one (1) year following the Original Issue Date, if (i)
the Per Share Market Value of one share of Common Stock is greater than the
Warrant Price (at the date of calculation as set forth below) and (ii) a
registration statement under the Securities Act providing for the resale of the
Warrant Stock is not then in effect by the date such registration statement is
required to be effective pursuant to the Registration Rights Agreement (as
defined in the Purchase Agreement) or not effective at any time during the
Effectiveness Period (as defined in the Registration Rights Agreement) in
accordance with the terms of the Registration Rights Agreement, in lieu of
exercising this Warrant by payment of cash, the Holder may exercise this Warrant
by a cashless exercise and shall receive the number of shares of Common Stock
equal to an amount (as determined below) by surrender of this Warrant at the
principal office of the Issuer together with the properly endorsed Notice of
Exercise in which event the Issuer shall issue to the Holder a number of shares
of Common Stock computed using the following formula:

              X = Y - (A)(Y)
                      ------
                         B

Where         X =      the number of shares of Common Stock to be issued to the
                       Holder.

              Y        = the number of shares of Common Stock purchasable
                       upon exercise of all of the Warrant or, if only a
                       portion of the Warrant is being exercised, the
                       portion of the Warrant being exercised.

              A =      the Warrant Price.

              B = the Per Share Market Value of one share of Common Stock.

      (d) Issuance of Stock Certificates. In the event of any exercise of the
rights represented by this Warrant in accordance with and subject to the terms
and conditions hereof, certificates for the shares of Warrant Stock so purchased
shall be dated the date of such exercise and delivered to the Holder hereof
within a reasonable time, not exceeding three (3) Trading Days after such
exercise (the "Delivery Date") or, at the request of the Holder (provided that a
registration statement under the Securities Act providing for the resale of the
Warrant Stock is then in effect), issued and delivered to the Depository Trust
Company ("DTC") account on the Holder's behalf via the Deposit Withdrawal Agent
Commission System ("DWAC") within a reasonable time, not exceeding three (3)
Trading Days after such exercise, and the Holder hereof shall be deemed for all
purposes to be the holder of the shares of Warrant Stock so purchased as of the
date of such exercise. The Holder shall deliver this original Warrant, or an
indemnification undertaking with respect to such Warrant in the case of its
loss, theft or destruction, at such time that this Warrant is fully exercised.
With respect to partial exercises of this Warrant, the Issuer shall keep written
records for the Holder of the number of shares of Warrant Stock exercised as of
each date of exercise.

<PAGE>

      (e) Compensation for Buy-In on Failure to Timely Deliver Certificates Upon
Exercise. In addition to any other rights available to the Holder, if the Issuer
fails to cause its transfer agent to transmit to the Holder a certificate or
certificates representing the Warrant Stock pursuant to an exercise on or before
the Delivery Date, and if after such date the Holder is required by its broker
to purchase (in an open market transaction or otherwise) shares of Common Stock
to deliver in satisfaction of a sale by the Holder of the Warrant Stock which
the Holder anticipated receiving upon such exercise (a "Buy-In"), then the
Issuer shall (1) pay in cash to the Holder the amount by which (x) the Holder's
total purchase price (including brokerage commissions, if any) for the shares of
Common Stock so purchased exceeds (y) the amount obtained by multiplying (A) the
number of shares of Warrant Stock that the Issuer was required to deliver to the
Holder in connection with the exercise at issue times (B) the price at which the
sell order giving rise to such purchase obligation was executed, and (2) at the
option of the Holder, either reinstate the portion of the Warrant and equivalent
number of shares of Warrant Stock for which such exercise was not honored or
deliver to the Holder the number of shares of Common Stock that would have been
issued had the Issuer timely complied with its exercise and delivery obligations
hereunder. For example, if the Holder purchases Common Stock having a total
purchase price of $11,000 to cover a Buy-In with respect to an attempted
exercise of shares of Common Stock with an aggregate sale price giving rise to
such purchase obligation of $10,000, under clause (1) of the immediately
preceding sentence the Issuer shall be required to pay the Holder $1,000. The
Holder shall provide the Issuer written notice indicating the amounts payable to
the Holder in respect of the Buy-In, together with applicable confirmations and
other evidence reasonably requested by the Issuer. Nothing herein shall limit a
Holder's right to pursue any other remedies available to it hereunder, at law or
in equity including, without limitation, a decree of specific performance and/or
injunctive relief with respect to the Issuer's failure to timely deliver
certificates representing shares of Common Stock upon exercise of this Warrant
as required pursuant to the terms hereof.

      (f) Transferability of Warrant. Subject to Section 2(h) hereof, this
Warrant, and the rights evidenced hereby, may be transferred by a Holder, in
whole or in part, without the consent of the Issuer, so long as the transferee
is an "accredited investor" as defined in Regulation D under the Securities Act
and agrees to be bound by all of the provisions of this Warrant. If transferred
pursuant to this paragraph, this Warrant may be transferred on the books of the
Issuer by the Holder hereof in person or by duly authorized attorney, upon
surrender of this Warrant at the principal office of the Issuer, properly
endorsed (by the Holder executing an assignment in the form attached hereto) and
upon payment of any necessary transfer tax or other governmental charge imposed
upon such transfer. This Warrant is exchangeable at the principal office of the
Issuer for warrants to purchase the same aggregate number of shares of Warrant
Stock, each new Warrant to represent the right to purchase such number of shares
of Warrant Stock as the Holder hereof shall designate at the time of such
exchange. All warrants issued on transfers or exchanges shall be dated the
Original Issue Date and shall be identical with this Warrant except as to the
number of shares of Warrant Stock issuable pursuant thereto.

<PAGE>

      (g) Continuing Rights of Holder. The Issuer will, at the time of or at any
time after each exercise of this Warrant, upon the request of the Holder hereof,
acknowledge in writing the extent, if any, of its continuing obligation to
afford to such Holder all rights to which such Holder shall continue to be
entitled after such exercise in accordance with the terms of this Warrant,
provided that if any such Holder shall fail to make any such request, the
failure shall not affect the continuing obligation of the Issuer to afford such
rights to such Holder.

      (h) Compliance with Securities Laws.

            (i) The Holder of this Warrant, by acceptance hereof, acknowledges
      that this Warrant and the shares of Warrant Stock to be issued upon
      exercise hereof are being acquired solely for the Holder's own account and
      not as a nominee for any other party, and for investment, and that the
      Holder will not offer, sell or otherwise dispose of this Warrant or any
      shares of Warrant Stock to be issued upon exercise hereof except pursuant
      to an effective registration statement, or an exemption from registration,
      under the Securities Act and any applicable state securities laws.

            (ii) Except as provided in paragraph (iii) below, this Warrant and
      all certificates representing shares of Warrant Stock issued upon exercise
      hereof shall be stamped or imprinted with a legend in substantially the
      following form:

                  THIS WARRANT AND THE SHARES OF COMMON STOCK ISSUABLE UPON
                  EXERCISE HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
                  ACT OF 1933, AS AMENDED (THE "SECURITIES ACT") OR ANY STATE
                  SECURITIES LAWS AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE
                  DISPOSED OF UNLESS REGISTERED UNDER THE SECURITIES ACT AND
                  UNDER APPLICABLE STATE SECURITIES LAWS OR THE ISSUER SHALL
                  HAVE RECEIVED AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO
                  THE ISSUER THAT REGISTRATION OF SUCH SECURITIES UNDER THE
                  SECURITIES ACT AND UNDER THE PROVISIONS OF APPLICABLE STATE
                  SECURITIES LAWS IS NOT REQUIRED.

<PAGE>

            (iii) The Issuer agrees, upon a Holder's reasonable request, to
      reissue certificates representing any of the Warrant Stock, without the
      legend set forth above (i) while a registration statement providing for
      the resale of such Warrant Stock is effective under the Securities Act,
      (ii) following any sale of such Warrant Stock pursuant to Rule 144
      (assuming the transferor is not an affiliate of the Issuer), (iii) if such
      Warrant Stock is eligible for sale under Rule 144(k) (to the extent that
      such Holder provides a certification or legal opinion to the Issuer to
      that effect), or (iv) if such legend is not required under applicable
      requirements of the Securities Act (including controlling judicial
      interpretations and pronouncements issued by the Securities and Exchange
      Commission). Following the effective date of the registration statement
      providing for the resale of such Warrant Stock or at such earlier time as
      a legend is no longer required for the Warrant Stock, the Issuer will,
      promptly following the delivery by the Holder to the Issuer or the
      Issuer's transfer agent of a legended certificate representing such
      Warrant Stock, deliver or cause to be delivered to the Holder a
      certificate representing such Warrant Stock that is free from all
      restrictive legends. The restrictions on transfer contained in this
      Section 2(h) shall be in addition to, and not by way of limitation of, any
      other restrictions on transfer contained in any other section of this
      Warrant. Whenever a certificate representing the Warrant Stock is required
      to be issued to the Holder without a legend, in lieu of delivering
      physical certificates representing the Warrant Stock (provided that a
      registration statement under the Securities Act providing for the resale
      of the Warrant Stock is then in effect), the Issuer shall cause its
      transfer agent to electronically transmit the Warrant Stock to the Holder
      by crediting the account of the Holder's Prime Broker with DTC through its
      DWAC system.

      (i) Accredited Investor. In no event may the Holder exercise this Warrant
in whole or in part unless the Holder is an "accredited investor" as defined in
Regulation D under the Securities Act.

      3. Stock Fully Paid; Reservation and Listing of Shares; Covenants.

      (a) Stock Fully Paid. The Issuer represents, warrants, covenants and
agrees that all shares of Warrant Stock which may be issued upon the exercise of
this Warrant or otherwise hereunder will, when issued in accordance with the
terms of this Warrant, be duly authorized, validly issued, fully paid and
non-assessable and free from all taxes, liens and charges created by or through
the Issuer. The Issuer further covenants and agrees that during the period
within which this Warrant may be exercised, the Issuer will at all times have
authorized and reserved for the purpose of the issuance upon exercise of this
Warrant a number of authorized but unissued shares of Common Stock equal to at
least one hundred percent (100%) of the number of shares of Common Stock
issuable upon exercise of this Warrant without regard to any limitations on
exercise.

      (b) Reservation. If any shares of Common Stock required to be reserved for
issuance upon exercise of this Warrant or as otherwise provided hereunder
require registration or qualification with any Governmental Authority under any
federal or state law before such shares may be so issued, the Issuer will in
good faith use its best efforts as expeditiously as possible at its expense to
cause such shares to be duly registered or qualified. If the Issuer shall list
any shares of Common Stock on any securities exchange or market it will, at its
expense, list thereon, and maintain and increase when necessary such listing,
of, all shares of Warrant Stock from time to time issued upon exercise of this
Warrant or as otherwise provided hereunder (provided that such Warrant Stock has
been registered pursuant to a registration statement under the Securities Act
then in effect), and, to the extent permissible under the applicable securities
exchange rules, all unissued shares of Warrant Stock which are at any time
issuable hereunder, so long as any shares of Common Stock shall be so listed.
The Issuer will also so list on each securities exchange or market, and will
maintain such listing of, any other securities which the Holder of this Warrant
shall be entitled to receive upon the exercise of this Warrant if at the time
any securities of the same class shall be listed on such securities exchange or
market by the Issuer.

<PAGE>

      (c) Covenants. The Issuer shall not by any action including, without
limitation, amending the Certificate of Incorporation or the by-laws of the
Issuer, or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities or any other action, avoid or
seek to avoid the observance or performance of any of the terms of this Warrant,
but will at all times in good faith assist in the carrying out of all such terms
and in the taking of all such actions as may be necessary or appropriate to
protect the rights of the Holder hereof against dilution (to the extent
specifically provided herein) or impairment. Without limiting the generality of
the foregoing, the Issuer will (i) not permit the par value, if any, of its
Common Stock to exceed the then effective Warrant Price, (ii) not amend or
modify any provision of the Certificate of Incorporation or by-laws of the
Issuer in any manner that would adversely affect the rights of the Holders of
the Warrant, (iii) take all such action as may be reasonably necessary in order
that the Issuer may validly and legally issue fully paid and nonassessable
shares of Common Stock, free and clear of any liens, claims, encumbrances and
restrictions (other than as provided herein) upon the exercise of this Warrant,
and (iv) use its best efforts to obtain all such authorizations, exemptions or
consents from any public regulatory body having jurisdiction thereof as may be
reasonably necessary to enable the Issuer to perform its obligations under this
Warrant.

      (d) Loss, Theft, Destruction of Warrant. Upon receipt of evidence
satisfactory to the Issuer of the ownership of and the loss, theft, destruction
or mutilation of any Warrant and, in the case of any such loss, theft or
destruction, upon receipt of indemnity or security satisfactory to the Issuer
or, in the case of any such mutilation, upon surrender and cancellation of such
Warrant, the Issuer will make and deliver, in lieu of such lost, stolen,
destroyed or mutilated Warrant, a new Warrant of like tenor and representing the
right to purchase the same number of shares of Common Stock.

      (e) Payment of Taxes. The Issuer will pay any documentary stamp taxes
attributable to the initial issuance of the Warrant Stock issuable upon exercise
of this Warrant; provided, however, that the Issuer shall not be required to pay
any tax or taxes which may be payable in respect of any transfer involved in the
issuance or delivery of any certificates representing Warrant Stock in a name
other than that of the Holder in respect to which such shares are issued.

      4. Adjustment of Warrant Price. The price at which such shares of Warrant
Stock may be purchased upon exercise of this Warrant shall be subject to
adjustment from time to time as set forth in this Section 4. The Issuer shall
give the Holder notice of any event described below which requires an adjustment
pursuant to this Section 4 in accordance with the notice provisions set forth in
Section 5.

<PAGE>

            (a) Recapitalization, Reorganization, Reclassification,
Consolidation, Merger or Sale. In case the Issuer after the Original Issue Date
shall do any of the following (each, a "Triggering Event"): (a) consolidate or
merge with or into any other Person and the Issuer shall not be the continuing
or surviving corporation of such consolidation or merger, or (b) permit any
other Person to consolidate with or merge into the Issuer and the Issuer shall
be the continuing or surviving Person but, in connection with such consolidation
or merger, any Capital Stock of the Issuer shall be changed into or exchanged
for Securities of any other Person or cash or any other property, or (c)
transfer all or substantially all of its properties or assets to any other
Person, or (d) effect a capital reorganization or reclassification of its
Capital Stock, then, and as a condition to each such Triggering Event, proper
and adequate provision shall be made so that, upon the basis and the terms and
in the manner provided in this Warrant, the Holder of this Warrant shall be
entitled upon the exercise hereof at any time after the consummation of such
Triggering Event, to the extent this Warrant is not exercised prior to such
Triggering Event, to receive at the Warrant Price in effect at the time
immediately prior to the consummation of such Triggering Event in lieu of the
Common Stock issuable upon such exercise of this Warrant prior to such
Triggering Event, the Securities, cash and property to which such Holder would
have been entitled upon the consummation of such Triggering Event if such Holder
had exercised the rights represented by this Warrant immediately prior thereto
(including the right of a shareholder to elect the type of consideration it will
receive upon a Triggering Event), subject to adjustments (subsequent to such
corporate action) as nearly equivalent as possible to the adjustments provided
for elsewhere in this Section 4.

            (b) Stock Dividends, Subdivisions and Combinations. If at any time
the Issuer shall:

                  (i) make or issue or set a record date for the holders of the
            Common Stock for the purpose of entitling them to receive a dividend
            payable in, or other distribution of, shares of Common Stock,

                  (ii) subdivide its outstanding shares of Common Stock into a
            larger number of shares of Common Stock, or

                  (iii) combine its outstanding shares of Common Stock into a
            smaller number of shares of Common Stock,

then (1) the number of shares of Common Stock for which this Warrant is
exercisable immediately after the occurrence of any such event shall be adjusted
to equal the number of shares of Common Stock which a record holder of the same
number of shares of Common Stock for which this Warrant is exercisable
immediately prior to the occurrence of such event would own or be entitled to
receive after the happening of such event, and (2) the Warrant Price then in
effect shall be adjusted to equal (A) the Warrant Price then in effect
multiplied by the number of shares of Common Stock for which this Warrant is
exercisable immediately prior to the adjustment divided by (B) the number of
shares of Common Stock for which this Warrant is exercisable immediately after
such adjustment.

<PAGE>

Notwithstanding the foregoing, if such record date shall have been fixed and
such dividend is not fully paid or if such distribution is not fully made on the
date fixed therefor, the Warrant Price shall be adjusted pursuant to this
paragraph as of the time of actual payment of such dividends or distributions.

      (c) Certain Other Distributions. If at any time the Issuer shall make or
issue or set a record date for the determination of the holders of the Common
Stock for the purpose of entitling them to receive any dividend or other
distribution of:

            (i) cash (other than a cash dividend payable out of earnings or
      earned surplus legally available for the payment of dividends under the
      laws of the jurisdiction of incorporation of the Issuer),

            (ii) any evidences of its indebtedness, any shares of stock of any
      class or any other securities or property of any nature whatsoever (other
      than cash), or

            (iii) any warrants or other rights to subscribe for or purchase any
      evidences of its indebtedness, any shares of stock of any class or any
      other securities or property of any nature whatsoever (other than cash),

then (1) the number of shares of Common Stock for which this Warrant is
exercisable shall be adjusted to equal the product of the number of shares of
Common Stock for which this Warrant is exercisable immediately prior to such
adjustment multiplied by a fraction (A) the numerator of which shall be the Per
Share Market Value of Common Stock at the date of taking such record and (B) the
denominator of which shall be such Per Share Market Value minus the amount
allocable to one share of Common Stock of any such cash so distributable and of
the fair value (as determined in good faith by the Board of Directors of the
Issuer) of any and all such evidences of indebtedness, shares of stock, other
securities or property or warrants or other subscription or purchase rights so
distributable, and (2) the Warrant Price then in effect shall be adjusted to
equal (A) the Warrant Price then in effect multiplied by the number of shares of
Common Stock for which this Warrant is exercisable immediately prior to the
adjustment divided by (B) the number of shares of Common Stock for which this
Warrant is exercisable immediately after such adjustment. A reclassification of
the Common Stock (other than a change in par value, or from par value to no par
value or from no par value to par value) into shares of Common Stock and shares
of any other class of stock shall be deemed a distribution by the Issuer to the
holders of its Common Stock of such shares of such other class of stock within
the meaning of this Section 4(c) and, if the outstanding shares of Common Stock
shall be changed into a larger or smaller number of shares of Common Stock as a
part of such reclassification, such change shall be deemed a subdivision or
combination, as the case may be, of the outstanding shares of Common Stock
within the meaning of Section 4(b).

Notwithstanding the foregoing, if such record date shall have been fixed and
such dividend is not fully paid or if such distribution is not fully made on the
date fixed therefor, the Warrant Price shall be adjusted pursuant to this
Section 4(c) as of the time of actual payment of such dividends or
distributions.

<PAGE>

      (d) Other Provisions Applicable to Adjustments under this Section. The
following provisions shall be applicable to the making of adjustments of the
number of shares of Common Stock for which this Warrant is exercisable and the
Warrant Price then in effect provided for in this Section 4:

            (i) Computation of Consideration. In connection with any merger or
consolidation in which the Issuer is the surviving corporation (other than any
consolidation or merger in which the previously outstanding shares of Common
Stock of the Issuer shall be changed to or exchanged for the stock or other
securities of another corporation), the amount of consideration therefor shall
be, deemed to be the fair value, as determined reasonably and in good faith by
the Board, of such portion of the assets and business of the nonsurviving
corporation as the Board may determine to be attributable to such securities. In
the event of any consolidation or merger of the Issuer in which the Issuer is
not the surviving corporation or in which the previously outstanding shares of
Common Stock of the Issuer shall be changed into or exchanged for the stock or
other securities of another corporation, or in the event of any sale of all or
substantially all of the assets of the Issuer for stock or other securities of
any corporation, the Issuer shall be deemed to have issued a number of shares of
its Common Stock for stock or securities or other property of the other
corporation computed on the basis of the actual exchange ratio on which the
transaction was predicated, and for a consideration equal to the fair market
value on the date of such transaction of all such stock or securities or other
property of the other corporation. In the event any consideration received by
the Issuer for any securities consists of property other than cash, the fair
market value thereof at the time of issuance or as otherwise applicable shall be
as determined in good faith by the Board. In the event Common Stock is issued
with other shares or securities or other assets of the Issuer for consideration
which covers both, the consideration computed as provided in this Section
4(d)(i) shall be allocated among such securities and assets as determined in
good faith by the Board.

            (ii) When Adjustments to Be Made. The adjustments required by this
Section 4 shall be made whenever and as often as any specified event requiring
an adjustment shall occur, except that any adjustment of the number of shares of
Common Stock for which this Warrant is exercisable that would otherwise be
required may be postponed (except in the case of a subdivision or combination of
shares of the Common Stock, as provided for in Section 4(b)) up to, but not
beyond the date of exercise if such adjustment either by itself or with other
adjustments not previously made adds or subtracts less than one percent (1%) of
the shares of Common Stock for which this Warrant is exercisable immediately
prior to the making of such adjustment. Any adjustment representing a change of
less than such minimum amount (except as aforesaid) which is postponed shall be
carried forward and made as soon as such adjustment, together with other
adjustments required by this Section 4 and not previously made, would result in
a minimum adjustment or on the date of exercise. For the purpose of any
adjustment, any specified event shall be deemed to have occurred at the close of
business on the date of its occurrence.

            (iii) Fractional Interests. In computing adjustments under this
Section 4, fractional interests in Common Stock shall be taken into account to
the nearest one one-hundredth (1/100th) of a share.

<PAGE>

            (iv) When Adjustment Not Required. If the Issuer shall take a record
of the holders of its Common Stock for the purpose of entitling them to receive
a dividend or distribution or subscription or purchase rights and shall,
thereafter and before the distribution to stockholders thereof, legally abandon
its plan to pay or deliver such dividend, distribution, subscription or purchase
rights, then thereafter no adjustment shall be required by reason of the taking
of such record and any such adjustment previously made in respect thereof shall
be rescinded and annulled.

      (e) Form of Warrant after Adjustments. The form of this Warrant need not
be changed because of any adjustments in the Warrant Price or the number and
kind of Securities purchasable upon the exercise of this Warrant.

      (f) Escrow of Warrant Stock. If after any property becomes distributable
pursuant to this Section 4 by reason of the taking of any record of the holders
of Common Stock, but prior to the occurrence of the event for which such record
is taken, and the Holder exercises this Warrant, any shares of Common Stock
issuable upon exercise by reason of such adjustment shall be deemed the last
shares of Common Stock for which this Warrant is exercised (notwithstanding any
other provision to the contrary herein) and such shares or other property shall
be held in escrow for the Holder by the Issuer to be issued to the Holder upon
and to the extent that the event actually takes place, upon payment of the
current Warrant Price. Notwithstanding any other provision to the contrary
herein, if the event for which such record was taken fails to occur or is
rescinded, then such escrowed shares shall be cancelled by the Issuer and
escrowed property returned.

      5. Notice of Adjustments. Whenever the Warrant Price or Warrant Share
Number shall be adjusted pursuant to Section 4 hereof (for purposes of this
Section 5, each an "adjustment"), the Issuer shall cause its Chief Financial
Officer to prepare and execute a certificate setting forth, in reasonable
detail, the event requiring the adjustment, the amount of the adjustment, the
method by which such adjustment was calculated (including a description of the
basis on which the Board made any determination hereunder), and the Warrant
Price and Warrant Share Number after giving effect to such adjustment, and shall
cause copies of such certificate to be delivered to the Holder of this Warrant
promptly after each adjustment. Any dispute between the Issuer and the Holder of
this Warrant with respect to the matters set forth in such certificate may, at
the option of the Holder, be submitted to an Independent Appraiser reasonably
acceptable to the Issuer and the Holder. The Issuer shall use its best efforts
to cause the Independent Appraiser to perform the calculations and notify the
Issuer and the Holder of the results no later than five (5) business days from
the time it receives the disputed calculation. Such Independent Appraiser's
calculation shall be binding upon all parties absent manifest error. The
reasonable expenses of the Independent Appraiser in making such determination
shall be paid by the Issuer, in the event the Holder's calculation was correct,
or by the Holder, in the event the Issuer's calculation was correct, or equally
by the Issuer and the Holder in the event that neither the Issuer's or the
Holder's calculation was correct.

      6. Fractional Shares. No fractional shares of Warrant Stock will be issued
in connection with any exercise hereof, but in lieu of such fractional shares,
the Issuer shall round the number of shares to be issued upon exercise up to the
nearest whole number of shares.

      7. Ownership Cap and Certain Exercise Restrictions. Notwithstanding
anything to the contrary contained in this Warrant, this Warrant shall not be
exercisable by the Holder hereof to the extent (but only to the extent) that, if
exercisable by the Holder, the Holder, any of its affiliates, or any other
Person which may be deemed to be acting as a group in concert with the Holder or
any of its affiliates for the purposes of Section 13(d) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), and the rules and
regulations promulgated thereunder, would beneficially own in excess of 4.9%
(the "Applicable Percentage") of the outstanding shares of common stock of the
Company. To the extent the above limitation applies, the determination of
whether this Warrant shall be exercisable (vis-a-vis other convertible,
exercisable or exchangeable securities owned by the Holder) and of which
warrants shall be exercisable (as among all warrants owned by the Holder) shall,
subject to such Applicable Percentage limitation, be determined by the Holder on
the basis of the first submission to the Company for conversion, exercise or
exchange (as the case may be). No prior inability to exercise this Warrant
pursuant to this paragraph shall have any effect on the applicability of the
provisions of this paragraph with respect to any subsequent determination of
exercisability. For the purposes of this paragraph, beneficial ownership and all
determinations and calculations (including, without limitation, with respect to
calculations of percentage ownership) shall be determined by the Holder in
accordance with Section 13(d) of the Exchange Act and the rules and regulations
promulgated thereunder. The provisions of this paragraph shall be implemented in
a manner otherwise than in strict conformity with the terms this paragraph to
correct this paragraph (or any portion hereof) which may be defective or
inconsistent with the intended Applicable Percentage beneficial ownership
limitation herein contained or to make changes or supplements necessary or
desirable to properly give effect to such Applicable Percentage limitation. The
limitations contained in this paragraph shall apply to a successor Holder of
this Warrant. The holders of common stock of the Company shall be third party
beneficiaries of this paragraph and the Company may not waive this paragraph
without the consent of holders of a majority of its common stock.

Mr. Paul Intlekofer
Chief Executive Officer
Nutrition 21, Inc.
4 Manhattanville Road
Purchase, NY 10577-2197

Dear Paul:

This letter ("Letter Agreement") represents our understanding of the basis upon
which C.E. Unterberg, Towbin, LLC, a Delaware limited liability company
("CEUT"), and Dresdner Kleinwort Wasserstein Securities LLC ("DrKW") are engaged
as co-advisors to provide financial advisory and investment banking services to
Nutrition 21, Inc. (the "Company"). This letter solely relates to such financial
advisory and investment banking services and not to any potential investment in
the Company by CEUT or DrKW.

1.    The Company hereby retains CEUT and DrKW to act as its co-exclusive
      financial advisors with respect to a best efforts private placement
      transaction of up to $10,000,000 of common stock, convertible notes, or
      convertible preferred stock (the "Securities"). The Company will not
      during the term of this engagement offer the Securities for sale to, or
      solicit any offers to buy from, any person or persons, whether directly or
      indirectly, otherwise than through CEUT and DrKW, provided, however, that
      under no circumstances shall CEUT or DrKW be liable for failure to obtain
      or produce the proposed financing, and provided further that the Company
      is not obligated to sell any Securities.

2.    As part of our engagement, CEUT and DrKW will provide the Company with the
      following services:

      a)    Identify and contact potential investors;

      b)    As necessary, with management of the Company, meet with potential
            investors approved by the Company and provide them with such
            information furnished by the Company as may be appropriate; and

      c)    Assist the Company in negotiating with identified potential
            investors.

3.    As compensation for the services rendered by CEUT and DrKW hereunder, the
      Company agrees to pay the following fees at the closing for the sale of
      the Securities to investors:

      a)    To CEUT:

            i)    a cash fee equal to 5.0% of the proceeds raised from
                  investors, excluding the first $2.25 million of proceeds
                  ("Excluded Proceeds") received from persons or entities who
                  were existing investors on April 25, 2006 and their affiliates
                  ("Existing Investors"); such proceeds other than Excluded
                  Proceeds are referred to herein as "Net Proceeds", and the
                  Securities purchased by investors for the Net Proceeds are
                  referred to herein as "Net Securities"; and

            ii)   common stock warrants (the "Warrants"), in the form of
                  warrants issued to investors and with an exercise price equal
                  to the purchase price of the Securities, to purchase a number
                  of shares equal to 2.0% of the shares of common stock or
                  common stock equivalents included in the Net Securities but
                  not including common stock issuable on exercise of warrants
                  issued to Investors;

                                       2
<PAGE>

      b)    TO DrKW:

            i)    a cash fee equal to 2.0% of the Net Proceeds; and

            ii)   Warrants to purchase a number of shares equal to 1.0% of the
                  shares of common stock or common stock equivalents included in
                  the Net Securities but not including common stock issuable on
                  exercise of warrants issued to Investors.

      c)    The common stock underlying the Warrants will be included in the
            registration statement filed related to the private placement
            transaction.

4.    The Company also agrees to reimburse CEUT, but not DrKW, for its counsel
      and out-of-pocket expenses, provided that the maximum liability of the
      Company under this sentence shall in no event exceed $30,000; provided,
      however, that nothing herein shall limit the indemnification provided for
      in paragraph 5 below.

5.    Each of CEUT and DrKW has entered into a separate letter agreement with
      the Company, dated the date hereof, providing for the indemnification of
      each of CEUT and DrKW by the Company in connection with the engagement
      hereunder, the terms of which are incorporated into this agreement in
      their entirety.

6.    The Company recognizes and confirms that each of CEUT and DrKW in acting
      pursuant to this engagement will be using publicly available information
      and information in reports and other materials provided by others,
      including, without limitation, information provided by or on behalf of the
      Company and that neither CEUT or DrKW assumes responsibility for and may
      rely, without independent verification, on the accuracy and completeness
      of any such information. The Company agrees to furnish or cause to be
      furnished to CEUT and DrKW all necessary or appropriate information for
      use in its engagement and hereby warrants that any information relating to
      the Company that is furnished to CEUT and DrKW on behalf of the Company,
      will be true and correct in all material respects and not misleading.

7.    The term of this engagement shall extend until the earlier of (i) closing
      of the private placement transaction and (ii) six (6) months from the date
      of this agreement, and shall automatically renew thereafter on a
      month-to-month basis until terminated in writing by either party. Any such
      termination shall not (except as provided herein) affect the compensation
      or indemnification provisions set forth herein, all of which shall remain
      in full force and effect. In addition, the Company shall be responsible
      for any fees as outlined above for any offering undertaken by the Company
      in lieu of the contemplated transaction described herein with any
      investors introduced by CEUT or DrKW that is concluded within nine months
      after the date of termination of this agreement.

8.    Notwithstanding their engagement as placement agents hereunder, neither
      CEUT or DrKW may, without its prior written consent, be quoted or referred
      to in any document, release or communication prepared, issued or
      transmitted by the Company (including any entity controlled by, or under
      common control with, the Company and any director, officer, employee or
      agent thereof).

9.Following completion of this engagement, each of CEUT and DrKW shall have the
right to place advertisements in financial and other newspapers and journals at
its own expense describing its services to the Company hereunder; subject to
prior written approval of the Company, which will not be unreasonably withheld.

10. This Agreement is governed by the laws of the State of New York, without
regard to such state's rules concerning conflicts of law, and will be binding
upon and inure to the benefit of the Company and CEUT and their respective
successors and assigns. The Company and CEUT and DrKW agree to waive trial by
jury in any action, proceeding or counterclaim brought by or on behalf of either
party with respect to any matter whatsoever relating to or arising out of any
actual or proposed transaction or the engagement of or performance by CEUT or
DrKW hereunder. The Company also hereby submits to the jurisdiction of the state
and federal courts located in New York County, New York in any proceeding
arising out of or relating to this Agreement, agrees not to commence any suit,
action or proceeding relating thereto except in such courts, and waives, to the
fullest extent permitted by law, the right to move to dismiss or transfer any
action brought in such court on the basis of any objection to personal
jurisdiction, venue or inconvenient forum. This agreement may be executed in two
or more counterparts, each of which shall be deemed to be an original, but all
of which shall constitute one and the same agreement.

                                       3

11. CEUT and DrKW have been retained under this agreement as independent
contractors with no fiduciary or agency relationship to each other, to the
Company or to any other party. The advice rendered by CEUT and DrKW pursuant to
this agreement is intended solely for the benefit and use of the Board of
Directors of the Company in considering the matters to which this agreement
relates, and the Company agrees that such advice may not be relied upon by any
other person, used for any other purpose or reproduced, disseminated, quoted or
referred to at any time, in any manner or for any purpose. The Company
acknowledges and agrees that in performing its services for the Company, (i) the
obligations of each of CEUT and DrKW shall under all circumstances be deemed to
be several and not joint; (ii) CEUT and DrKW are not employees or agents of one
another, neither shall have any liability to the Company arising from the acts
or omissions of the other, and neither shall have any authority to bind the
other vis-a-vis any third party; and (iii) the rights of each of CEUT and DrKW
and other indemnified persons and the obligations of the Company under each
separate letter agreement referred to in paragraph 5 hereof shall be determined
without reference to the rights of the indemnified parties and the obligations
of the Company under the other separate letter agreement referred to in
paragraph 5 hereof.

12. The Company acknowledges that each of CEUT and DrKW and their affiliates may
have and may in the future have investment banking and other relationships with
parties other than the Company, which parties may have interests with respect to
this placement. Although CEUT and DrKW in the course of such other relationships
may acquire information about the placement, potential purchasers of the
Securities or such other parties, neither CEUT nor DrKW shall have any
obligation to disclose such information to the Company or to use such
information on behalf of the Company. Furthermore, the Company acknowledges that
CEUT and DrKW may have fiduciary or other relationships whereby CEUT and DrKW
may exercise voting power over securities of various persons, which securities
may from time to time include securities of the Company or of potential
purchasers of the Securities or others with interests in respect of the
placement. The Company acknowledges that each of CEUT and DrKW may exercise such
powers and otherwise perform its functions in connection with such fiduciary or
other relationships without regard to its relationship to the Company hereunder.

13. Please note that each of CEUT and DrKW is a full service securities firm
engaged in securities trading and brokerage activities, as well as providing
investment banking, financing and financial advisory services. In the ordinary
course of our trading, brokerage and financing activities, each of CEUT and DrKW
and their affiliates may at any time hold long or short positions, and may trade
or otherwise effect transactions, for our own account or the accounts of
customers, in debt or equity securities or senior loans of the Company.

If the foregoing correctly sets forth the understanding and agreement between
CEUT, DrKW and the Company, please so indicate in the space provided for that
purpose below, together with the enclosed duplicate original, and return one (1)
of these originals to us, whereupon this letter shall constitute a binding
agreement as of the date hereof.

Sincerely,

C.E. Unterberg, Towbin, LLC

New York, New York 10017

Ladies and Gentlemen:

In connection with the engagement of C.E. Unterberg, Towbin, LLC, a Delaware
limited liability company ("CEUT"), to advise and assist Nutrition 21, Inc. (the
"Company") with the subject matter in the letter agreement dated the date hereof
between CEUT and the Company, the Company agrees that it will indemnify and hold
harmless CEUT and its affiliates and their respective directors, officers,
agents and employees and each other person controlling CEUT or any of CEUT's
affiliates (collectively, the "Indemnified Parties"), to the full extent lawful,
from and against any losses, expenses, claims or proceedings (collectively,
"losses") (i) related to or arising out of (A) oral or written information
provided by the Company, its employees or other agents, which information either
the Company or CEUT provide to any actual or potential buyers, sellers,
investors or offerees, or (B) any other action or failure to act by the Company,
its directors, officers, agents or employees or by CEUT or any Indemnified Party
at the Company's request or with the Company's consent, or (ii) otherwise
related to or arising out of the engagement or any transaction or conduct in
connection therewith and resulting primarily from the Company's negligence, bad
faith or willful misconduct, except that these clauses (i) and (ii) shall not
apply with respect to (x) any losses that are finally judicially determined to
have resulted primarily from the gross negligence or willful misconduct of such
Indemnified Party, or (y) any amount paid in settlement of claims without the
Company's consent, which consent will not be unreasonably withheld.

In the event that the foregoing indemnity is unavailable to any Indemnified
Party for any reason (other than as a consequence of a final judicial
determination of willful misconduct, bad faith or gross negligence of such
Indemnified Party), then the Company agrees to contribute to any losses related
to or arising out of the engagement or any transaction or conduct in connection
therewith as follows. With respect to such losses referred to in clause (i) of
the preceding paragraph, each of the Company and CEUT shall contribute in such
proportion as is appropriate to reflect the relative benefits received (or
anticipated to be received) by CEUT, on the one hand, and by the Company and its
security holders, on the other hand, from the actual or proposed transaction
arising in connection with the engagement. With respect to any other losses, and
for losses referred to in clause (i) of the preceding paragraph if the
allocation provided by the immediately preceding sentence is unavailable for any
reason, each of the Company and CEUT shall contribute in such proportion as is
appropriate to reflect not only the relative benefits as set forth above, but
also the relative fault of each of the Company and CEUT in connection with the
statements, omissions or other relevant equitable considerations. Benefits
received (or anticipated to be received) by the Company and its security holders
shall be deemed to be equal to the aggregate cash consideration and value of
securities or any other property payable, issuable, exchangeable or transferable
in such transaction or proposed transaction, and benefits received by CEUT shall
be deemed to be equal to the compensation paid by the Company to CEUT (whether
in cash or otherwise) in connection with the engagement (exclusive of amounts
paid for reimbursement of expenses or paid under this agreement). Relative fault
shall be determined by reference to, among other things, whether any alleged
untrue statement or omission or any other alleged conduct relates to information
provided by the Company or other conduct by the Company (or its employees or
other agents), on the one hand, or by CEUT, on the other hand. CEUT and the
Company agree that it would not be just and equitable if contribution were
determined by pro rata allocation or by any other method of allocation that does
not take account of the equitable considerations referred to above.
Notwithstanding anything to the contrary above, in no event shall CEUT be
responsible for any amounts in excess of the amount of the compensation actually
paid by the Company to CEUT (in cash or otherwise) in connection with the
engagement (exclusive of amounts paid for reimbursement of expenses or paid
under this agreement).

                                       1
<PAGE>

Promptly after CEUT receives notice of the commencement of any action or other
proceeding in respect of which indemnification or reimbursement may be sought
hereunder, CEUT will notify the Company thereof; but the omission so to notify
the Company shall not relieve the Company from any obligation hereunder unless,
and only to the extent that, such omission results in its forfeiture of
substantive rights or defenses. If any such action or other proceeding shall be
brought against any Indemnified Party, the Company shall, upon written notice
given reasonably promptly following CEUT's notice to the Company of such action
or proceeding, be entitled to assume the defense thereof at its expense with
counsel chosen by the Company and reasonably satisfactory to the Indemnified
Parties; provided, however, that any Indemnified Party may at its own expense
retain separate counsel to participate in such defense. Notwithstanding the
foregoing, such Indemnified Party shall have the right to employ separate
counsel at the Company's expense and to control its own defense of such action
or proceeding if, in the reasonable opinion of counsel to such Indemnified
Party, (i) there are legal defenses available to such Indemnified Party or to
other indemnified parties that are different from or additional to those
available to the Company, or (ii) a conflict or likely conflict exists between
the Company and such Indemnified Party that would make such separate
representation advisable; provided, however, that in no event shall the Company
be required to pay fees and expenses under this indemnity for more than one
counsel in any one legal action or group of related legal actions, and provided
further that the Company will pay the fees and expense of such counsel only to
the extent reasonable. The Company agrees that it will not, without the prior
written consent of CEUT, which consent shall not be unreasonably withheld or
delayed, settle or compromise or consent to the entry of any judgment in any
pending or threatened claim, action or proceeding relating to the matters that
are the subject of CEUT's engagement (whether or not any Indemnified Party is a
party thereto) unless such settlement, compromise or consent includes an
unconditional release of CEUT and each other Indemnified Party from all
liability arising or that may arise out of such claim, action or proceeding.

The Company further agrees that no Indemnified Party shall have any liability
(whether direct or indirect, in contract or tort or otherwise) to the Company or
any of its affiliates, creditors or security holders for or in connection with
the engagement or any actual or proposed transactions or other conduct in
connection therewith except for losses incurred by the Company that are finally
judicially determined to have resulted primarily from the gross negligence or
willful misconduct of such Indemnified Party or have resulted from a breach of
the engagement between the Company and CEUT.

The foregoing agreement is in addition to any rights CEUT may have at common law
or otherwise and shall be binding on and inure to the benefit of any successors,
assigns, and personal representatives of the Company and each Indemnified Party.
This agreement is governed by the laws of the State of New York, without regard
to such state's rules concerning conflicts of laws. Each of the parties hereto
also hereby submits to the jurisdiction of the state and federal courts located
in New York County, New York in any proceeding arising out of or relating to
this agreement, agrees not to commence any suit, action or proceeding relating
hereto except in such courts, and waives, to the fullest extent permitted by
law, the right to move to dismiss or transfer any action brought in such court
on the basis of any objection to personal jurisdiction, venue or inconvenient
forum. Solely for purposes of enforcing this agreement, each party hereby
consents to personal jurisdiction, service of process and venue in any court in
which any claim or proceeding that is subject to this agreement is brought
against the other party. Any right to trial by jury with respect to any claim or
proceeding related to or arising out of the engagement, or any transaction or
conduct in connection therewith or this agreement is waived.

                                       2

This agreement shall remain in full force and effect notwithstanding the
completion or termination of the engagement.

                                               Very truly yours,

                                               Nutrition 21, Inc.
