limitation, the payment of any fees and taxes required in the granting of the
security interests created hereby and the filing of any financing statements or
other documents in connection herewith. If any amount payable under or in
connection with any of the Collateral shall be or become evidenced by any

immediately pledged and delivered to AHPC, duly endorsed in a manner reasonably
satisfactory to AHPC. WOMEN FIRST agrees promptly to notify AHPC of any change

prosecute any and all continuations, continuations-in-part, applications for
reissue, applications for certificates of correction, affidavits of use, proofs

or cause to be taken all reasonable actions to not allow any material patent,
copyright, trademark, service mark or any application for patent, trademark,
trade name, service mark or like protection relating to the Collateral to lapse,

public without the express written approval of AHPC.

                      ---------------------------
may designate shall have the right, at any reasonable time or times during WOMEN
FIRST's usual business hours, and upon reasonable notice (which may be
telephonic), to inspect the Collateral owned by WOMEN FIRST, all records related
thereto, and the premises upon which any such Collateral is located, to discuss
WOMEN FIRST's affairs with its officers and its independent accountants and to
verify under reasonable procedures the validity, amount, quality, quantity,
value, and condition of or any other matter relating to, such Collateral;

cooperative responses and actions taken or caused to be taken by WOMEN FIRST
shall be limited in scope to the Collateral and information appropriate for

preservation of the Collateral to the extent WOMEN FIRST fails to do so, and
WOMEN FIRST agrees to reimburse AHPC on demand for any payment made or any
out-of-pocket expense incurred by it pursuant to the foregoing authorization;
provided, however, that nothing in this Section 5 shall be interpreted as
--------  -------
excusing WOMEN FIRST from the performance of any covenants or other promises
with respect to taxes, liens, security interests or other encumbrances and
maintenances as set forth herein or in the Asset Purchase Agreement.

               6.     Representations and Warranties. WOMEN FIRST represents and

                      -------------------
         accordance with the Asset Purchase Agreement, the Trademark License
         Agreement and the transactions contemplated thereby, WOMEN FIRST has

         hereunder and good title to all Collateral owned by it and has full
         corporate power and authority to grant to AHPC the Security Interest in
         such Collateral pursuant hereto and to execute, deliver and perform its

         consent or approval of any other person other than any consent or
         approval which has been obtained.

               (b)    Filing. Fully executed UCC financing statements containing
                      ------
         a description of the Collateral shall be filed of record in every
         governmental, municipal or other office in every jurisdiction in which
         any portion of the Collateral is located necessary to establish and
         maintain a valid, legal and perfected security interest in favor of
         AHPC in respect of the Collateral in which a security interest may be
         perfected by filing in the United States and its territories and
         possessions, and no further or, assuming no future change in current
         law, subsequent filing, refiling, recording, rerecording, registration
         or

                                      -3-

         provided under applicable law with respect to the filing of UCC
         continuation statements.

               (c)    Validity of Security Interest. The Security Interest
                      -----------------------------
         constitutes a valid, legal and enforceable first priority security
         interest in all of the Collateral, subject, as to the enforcement of
         remedies, to applicable bankruptcy, reorganization, insolvency and
         similar laws and to moratorium laws from time to time in effect and
         except that the remedy of specific performance may not be available in
         all circumstances, which security interest shall be perfected under the
         timely filing of UCC financing statements pursuant to Section 6(b)
         hereof, for payment and performance of the Obligations.

               (d)    Information Regarding Names. WOMEN FIRST has disclosed in
                      ---------------------------

         in the ownership of its properties.

               (e)    Absence of Other Liens. To the extent conveyed by AHPC in
                      ----------------------
         accordance with the Asset Purchase Agreement, the Trademark License

         owned by WOMEN FIRST free and clear of any mortgage, pledge, security
         interest, lien, charge or other encumbrance of any nature whatsoever,
         except as granted pursuant to this Agreement and except as provided by
         paragraph (b) of this Section 6, WOMEN FIRST has not (i) filed any

         which WOMEN FIRST assigns the Collateral or any security agreement or
         similar instrument covering any Collateral with any foreign
         governmental, municipal or other office.

               (f)    Survival or Representations and Warranties. All
                      ------------------------------------------
         representations and warranties of the grantor contained in this
         Agreement shall survive the execution, delivery and performance of this
         Agreement until the termination of this Agreement pursuant to Section
         26.

               7.     Supplemental Documentation. In connection with the

the date of such certificate, all representations and warranties of WOMEN FIRST
in Section 6 are true and correct in all material respects and that WOMEN FIRST
is in compliance with all conditions, agreements and covenants to be observed or
performed hereunder in all material respects.

               8.     Protection of Security. (a) WOMEN FIRST shall, at its own
                      ----------------------
cost and expense, (i) take any and all actions necessary to defend title to the
Collateral owned by it against all persons (other than AHPC in the Event of
Default which has not been cured under the

                                      -4-

<PAGE>

Promissory Note) and to defend the Security Interest of AHPC in such Collateral,
and the priority thereof, against any adverse mortgage, pledge, security
interest, lien, charge or other encumbrance of any nature whatsoever, (ii) use
its commercially reasonable best efforts to detect any infringement of the
rights described herein and (iii) forthwith advise AHPC in writing of material
infringements detected.

         (b) If WOMEN FIRST fails to comply with the foregoing, AHPC, after five
(5) days' written notice to WOMEN FIRST, may do so in WOMEN FIRST's name jointly
or severally to the extent permitted by law, but at WOMEN FIRST's expense, and
WOMEN FIRST hereby agrees to reimburse AHPC in full for all reasonable expenses,
including reasonable attorneys' fees, incurred by AHPC in protecting, defending,
and maintaining the Collateral.

               9.     Continuing Obligations of the Grantors. WOMEN FIRST shall
                      --------------------------------------
remain liable to observe and perform all the conditions and obligations to be
observed and performed by it under each material contract, agreement, interest
or obligation relating to the Collateral, all in accordance with the terms and
conditions thereof, and shall indemnify and hold harmless AHPC from any and all
such liabilities, except to the extent that such liabilities arise solely as a
result of the gross negligence or willful misconduct of AHPC.

               10.    Use and Disposition of Collateral. Except to the extent
                      ---------------------------------
expressly permitted in the Asset Purchase Agreement, the Trademark License
Agreement or any related agreements executed at the Closing, WOMEN FIRST shall
not make or permit to be made any assignment, pledge or hypothecation of the
Collateral, or grant any other security interest in the Collateral. Except to
the extent expressly permitted in the Asset Purchase Agreement (including
without limitation the right to assign under Section 8.6 thereof), the Trademark
License Agreement or any related agreements executed at the Closing, WOMEN FIRST
shall not make or permit to be made any transfer of any Collateral other than
together with this Agreement in accordance with Section 19 hereof, and WOMEN
FIRST shall remain at all times in possession of the Collateral (other than for
use purposes only (upon advance notice to AHPC with regard to physical assets)
to the extent necessary, in WOMEN FIRST's discretion, to enable third-party
manufacturers, distributors and service providers to manufacture, distribute and
provide services with respect to the Collateral) owned by it other than
transfers to AHPC pursuant to the provisions hereof, except that so long as no
Event of Default shall have occurred and be continuing, WOMEN FIRST may exercise
its rights with respect to the Collateral so long as the exercise of such rights
                                          -- ---- --
are not inconsistent with the provisions of the Asset Purchase Agreement, the
Trademark License Agreement, any related agreements executed at the Closing or
this Security Agreement.

               11.    Collections. Upon the occurrence and during the
                      -----------
continuance of an Event of Default (provided that with respect to an Event of
Default described solely in Section 4(e) of the Promissory Note and no other
defaults thereunder, the rights afforded AHPC under this Section shall not
become effective without WOMEN FIRST's consent until 15 days following the
occurrence of such Event of Default and only if such Event of Default is
continuing) AHPC shall have the right, as the true and lawful agent of WOMEN
FIRST, with power of substitution for

                                      -5-

<PAGE>

WOMEN FIRST and in WOMEN FIRST's name, AHPC's name or otherwise, for the use and
benefit of AHPC (a) to receive, endorse, assign and/or deliver any and all
notes, acceptances, checks, drafts, money orders or other evidences of payment
relating to the Collateral or any part thereof; (b) to demand, collect, receive
payment of, give receipt for and give discharges and releases of all or any of
the Collateral; (c) to commence and prosecute any and all suits, actions or
proceedings at law or in equity in any court of competent jurisdiction to
collect or otherwise realize on all or any of the Collateral or to enforce any
rights in respect of any Collateral; and (d) to settle, compromise, compound,
adjust or defend any actions, suits or proceedings relating to or pertaining to
all or any of the Collateral, as fully and completely as though AHPC were the
absolute owner of the Collateral for all purposes; provided, however, that
                                                   --------  -------
nothing herein contained shall be construed as requiring or obligating AHPC to
make any commitment or to make any inquiry as to the nature or sufficiency of
any payment received by AHPC, or to present or file any claim or notice, or to
take any action with respect to the Collateral or any part thereof or the moneys
due or to become due in respect thereof or any property covered thereby, and no
action taken by AHPC or omitted to be taken with respect to the Collateral or
any part thereof shall give rise to any defense, counterclaim or offset in favor
of WOMEN FIRST or to any claim or action against AHPC in the absence of the
gross negligence or willful misconduct of AHPC. It is understood and agreed that
the appointment of AHPC as the agent of WOMEN FIRST for the purposes set forth
above in this Section 11 is coupled with an interest and is irrevocable. The
provisions of this Section 11 shall in no event relieve WOMEN FIRST of any of
its obligations hereunder or under the Asset Purchase Agreement with respect to
the Collateral or any part thereof or impose any obligation on AHPC to proceed
in any particular manner with respect to the Collateral or any part thereof, or
in any way limit the exercise by AHPC or any other or further right which it may
have on the date of this Agreement or hereafter, whether hereunder or by law or
otherwise.

               12.    Remedies upon Default. Upon the occurrence and during the
                      ---------------------
continuance of an Event of Default, WOMEN FIRST agrees to deliver each item of
Collateral to AHPC on demand at any reasonable place or places designated by
AHPC, and it is agreed that AHPC shall have the right to take any or all of the
following actions at the same or different times to the extent permitted by law:
with or without judicial process and with or without previous notice or demand
for performance, to take possession of the Collateral and without liability for
trespass to enter any premises where the Collateral may be located for the
purpose of taking possession of or removing the Collateral and, generally, to
exercise any and all rights afforded to a secured party under the UCC or other
applicable law. Without limiting the generality of the foregoing, WOMEN FIRST
agrees that AHPC shall have the right, subject to the mandatory requirements of
applicable law, to sell or otherwise dispose of all or any part of the
Collateral, at public or private sale or at any broker's board, for cash, upon
credit or for future delivery as AHPC shall deem appropriate. Upon consummation
of any such sale, AHPC shall have the right to assign, transfer and deliver to
the purchaser or purchasers thereof the Collateral so sold. AHPC's sale to such
purchaser shall transfer all of WOMEN FIRST's rights in the Collateral and WOMEN
FIRST hereby waives (to the extent permitted by law) all rights of redemption,
stay and appraisal which it now has or may at any time in the future have under
any rule of law or statute now existing or hereafter enacted.

                                      -6-

<PAGE>

               AHPC shall give WOMEN FIRST 10 days' written notice (which WOMEN
FIRST agrees is reasonable notice within the meaning of the UCC) of AHPC's
intention to make any sale of Collateral. Such notice, in the case of a public
sale, shall state the time and place for such sale and, in the case of a sale at
a broker's board, shall state the board at which such sale is to be made and the
day on which the Collateral, or portion thereof, will first be offered for sale
at such board. Any such public sale shall be held at such time or times within
ordinary business hours and at such place or places as AHPC may fix and state in
the notice (if any) of such sale. At any such sale, the Collateral, or portion
thereof, to be sold may be sold in one lot as an entirety or in separate
parcels, as AHPC may (in its sole and absolute discretion) determine. AHPC shall
not be obligated to make any sale of any Collateral if it shall determine not to
do so, regardless of the fact that notice of sale of such Collateral shall have
been given. AHPC may, without notice or publication, adjourn any public or
private sale or cause the same to be adjourned from time to time by announcement
at the time and place fixed for sale, and such sale may, without further notice,
be made at the time and place to which the same was so adjourned. In case any
sale of any or any part of the Collateral is made on credit or for future
delivery, the Collateral so sold may be retained by AHPC until the sale price is
paid by the purchaser or purchasers thereof, but AHPC shall not incur any
liability in case any such purchaser or purchasers shall fail to take up and pay
for the Collateral so sold and, in case of any such failure, such Collateral may
be sold again upon like notice. At any public sale made pursuant to this Section
12, AHPC may bid or purchase, free (to the extent permitted by law) from any
right of redemption, stay or appraisal on the part of WOMEN FIRST (all said
rights being also hereby waived and released to the extent permitted by law),
the Collateral or any part thereof offered for sale and may make payment on
account thereof by using any claim then due and payable to AHPC from WOMEN FIRST
as a credit against the purchase price, and AHPC may, upon compliance with the
terms of sale, hold, retain and dispose of such property without further
accountability to WOMEN FIRST therefor. For purposes hereof, a written agreement
to purchase the Collateral or any portion thereof shall not be treated as a sale
thereof; AHPC shall be free to carry out such sale pursuant to such agreement,
and WOMEN FIRST shall not be entitled to the return of the Collateral or any
portion thereof subject thereto, notwithstanding the fact that after AHPC shall
have entered into such an agreement all Events of Default shall have been
remedied and the Obligations paid in full. As an alternative to exercising the
power of sale herein conferred upon it, AHPC may proceed by a suit or suits at
law or in equity to foreclose this Agreement and to sell the Collateral or any
portion thereof pursuant to a judgment or decree of a court or courts having
competent jurisdiction or pursuant to a proceeding by a court-appointed
receiver.

               13.    Application of Proceeds. AHPC shall apply the proceeds of
                      -----------------------
any collection or sale of the Collateral as follows:

               FIRST, to (i) the payment of all reasonable costs and expenses
         incurred by AHPC in connection with such collection or sale or
         otherwise in connection with this Agreement or any of the Obligations,
         including, but not limited to, all court costs and the reasonable fees
         and expenses of its agents and legal counsel, the repayment of all
         advances made by

                                      -7-

<PAGE>

         AHPC hereunder on behalf of WOMEN FIRST and any other costs or expense
         incurred in connection with the exercise of any right or remedy
         hereunder; and (ii) the payment in full of principal and interest in
         respect of the Loan outstanding; and

               SECOND, to WOMEN FIRST, its respective successors and assigns, or
         as a court of competent jurisdiction may otherwise direct.

               14.    Locations of Collateral; Place of Business.
                      ------------------------------------------

               (a)    WOMEN FIRST hereby represents and warrants that all the
         Collateral is located at the locations listed on Schedule I hereto,
         which may include (upon advance written notice to AHPC with regard to
         physical assets) locations of third-party manufacturers, distributors
         and service providers to the extent necessary, in WOMEN FIRST's
         discretion, to manufacture, distribute and provide services with
         respect to the Collateral. WOMEN FIRST agrees not to establish, or
         permit to be established, any other location for Collateral unless all
         filings under the UCC or otherwise which are required by this Agreement
         or the Asset Purchase Agreement to be made with respect to the
         Collateral have been made and AHPC has a valid, legal and perfected
