         4.4 Purchase Orders. All purchase orders for Licensed Products shall be
initiated in writing by Collagen and shall include a requested delivery date.
Such purchase orders should be received by Cosmederm at least * prior to such
requested delivery date. The minimum aggregate purchase order size is * and the
minimum purchase order size per SKU is * . All purchase orders shall be
non-cancelable. All purchase orders, to the extent they would result in calendar
quarter deliveries not in excess of * of the amount last forecasted by Collagen
for such period, shall be shipped by the later of (i) * after receipt of such
order, or (ii) by the shipment request date set forth on such purchase order.
Any purchase order, to the extent it would result in calendar quarter deliveries
in excess of * of the amount last forecasted by Collagen for such period and
which is not (as to such excess amount) rejected by Cosmederm within * of
receipt shall be deemed accepted by Cosmederm upon its receipt of such purchase
order, and shall be shipped by the later of (i) * after receipt of such order,
or (ii) by the shipment request date set forth on such purchase order. In any
event, Cosmederm will use its reasonable best efforts to deliver Licensed
Products at the times and in the amounts specified in Collagen's accepted

failure to meet the delivery time specified in a purchase order.

         4.5 Forecasts. Commencing with Collagen's first order for Licensed
Products, and at the beginning of each calendar quarter thereafter, Collagen
shall provide Cosmederm rolling written forecasts of Collagen's estimated
requirements of Licensed Products to be delivered for each of the * . Forecasts
provided to Cosmederm by Collagen pursuant to this Section 4.5 shall be prepared
in good faith by Collagen and represent Collagen's reasonable expectation of its
purchase requirements for the forecasted period, but shall be advisory in nature
only and shall not be binding on Collagen. Cosmederm shall be prepared to
deliver at * of Collagen's last forecasted needs for a given calendar quarter.
The "last" forecast refers to the forecast for a quarter delivered * before the
first day of such quarter. Cosmederm and Collagen shall keep each other apprised
in good faith of their respective requirements, projections, production
capability limitations and similar matters.

         4.6 Conflicting Terms. In ordering and delivering the Licensed Products
hereunder, Cosmederm and Collagen may use their standard forms, but nothing in
such form shall be construed to amend or modify the terms of this Agreement and,
in the case of conflict herewith, the terms of this Agreement shall control.

         4.7 Certificate of Conformity. All Licensed Products delivered by

Conformity issued by Cosmederm warranting that all Licensed Products delivered
under such Certificate of Conformity shall meet the acceptance specifications to
be mutually agreed and called out in Exhibit B, including, but not limited to,
labeling, packaging and product specifications (the "Acceptance
Specifications.") Cosmederm will promptly replace (or, at Cosmederm's sole
option in any particular case, give Collagen credit for such returns at
Collagen's published wholesale prices) any and all Licensed Products returned by
a customer or an enduser within * of purchase and forwarded by Collagen to
Cosmederm within * of such return to the extent any such returns result from the
formulation and/or manufacture by Cosmederm of Licensed Products which do not
meet the Acceptance Specifications.

         4.8 Acceptance. Acceptance by Collagen of Licensed Products delivered
by Cosmederm shall be pursuant to the Certificate of Conformity issued by
Cosmederm pursuant to Section 4.7 and visual inspection by Collagen. Collagen's
failure to send a written rejection notice within * after delivery shall
conclusively be deemed to constitute acceptance. In the event that any shipment,
or part of any shipment, is found upon such visual inspection not to be in
accordance with the Acceptance Specifications, Collagen shall have the right to
reject such shipment, or part of shipment, within * after delivery by Cosmederm;
provided, that such shipment, or part of shipment, has not been used up by
Collagen or shipped to customers. A shipment, or part of a shipment, may be
rejected by Collagen only upon written notice to Cosmederm stating the reason(s)
for rejection. Upon receiving any such notice, Cosmederm shall use its
reasonable best efforts to replace rejected Licensed Products, and to redeliver
to Collagen replacement Licensed Products as soon as possible and in no event
more than * after Cosmederm's receipt of Collagen's written notice of rejection
(or, at Cosmederm's sole option in any particular case, give Collagen credit for
such rejected Licensed Products at Collagen's published wholesale prices).

         4.9 Shipment. All shipments will be FOB Collagen's manufacturing
facility in Fremont, California and/or such other place(s) as Collagen shall
direct. Risk of loss will pass to Collagen upon delivery to such facility. ** .
Cosmederm will be responsible for filing any and all freight claims. Collagen
may request a specific carrier and mode of shipment, but Cosmederm may arrange
for an alternative carrier and mode of shipment, provided that Collagen consents
to such alternative carrier and mode of shipment, such consent to not be
unreasonably withheld. Notwithstanding the foregoing, if Collagen's choice of
specific carriers, choice of mode of shipment, choice of ship-to location(s)
outside the continental United States, and/or direction to ship to multiple
locations results in higher freight, insurance and/or other shipping expenses
than using Cosmederm's normal truck delivery to a single location in the
continental United States, then Collagen shall pay the excess.

         4.10 Payment. Collagen shall pay Cosmederm the transfer price specified
in Section 5.1 within * after receiving an invoice covering an accepted order.

         4.11 Inspection of Manufacturing Facilities and Process. At any time
during the term of this Agreement, Collagen shall have the right to have, at
Collagen's expense, and Cosmederm shall permit, Collagen's authorized
representative(s) to inspect the manufacture of Licensed Products. Cosmederm
agrees at all times to provide Collagen at least * notice in writing prior to
the scheduled date of a manufacturing run of Licensed Products so that Collagen
representative(s) may be present.

5.0      Transfer Prices and Payment of Transfer Prices.

         5.1 Transfer prices for any and all Licensed Product(s) initially
specified in Exhibit A which are manufactured by Cosmederm pursuant to the first
sentence of Section 4.1 shall be calculated as * of Collagen's published
wholesale price of such Licensed Product as of the date of delivery by
Cosmederm. Collagen shall promptly notify Cosmederm of all changes in its

                                      -6-

published wholesale prices. The parties shall mutually agree upon the transfer
prices for any additional Licensed Products manufactured by Cosmederm pursuant
to Sections 7.1 and 7.2. Collagen agrees upon Cosmederm's request to discuss in
good faith adjusting the transfer price for the Licensed Product(s) initially
specified in Exhibit A upon Cosmederm's demonstration of convincing evidence of
commercial factors in support of such a proposed adjustment. The parties shall
mutually agree upon the size, quantity, packaging and transfer price, if any,
for sample products.

6.0      Royalty.

         6.1 Royalty Rates. In the event that Collagen manufactures or
sublicenses the manufacture of Licensed Product(s) under the second sentence of
Section 4.1, Collagen shall pay to Cosmederm royalties based on the Net Sales of
such Licensed Product(s) and calculated at the rate of (i) * for each and every
such Licensed Product(s) which is a prescription drug, (ii) * for each and every
such Licensed Product(s) which is classified as an OTC drug, but does not
require a physician's prescription, and (iii) * for each and every such Licensed
Product(s) which is a cosmetic product. The parties acknowledge that each of the
initial * Licensed Products specified in Exhibit A are cosmetic products and
shall agree on the characterization of any additional Licensed Products prior to
manufacture.

         6.2 Royalty Rate Adjustment. In the event that in any given calendar
year during the effective term of this Agreement, the cumulative Net Sales of
all royalty-bearing Licensed Products sold throughout the Territory which are
cosmetic products exceeds * , the applicable royalty rate for sales of such
royalty-bearing, cosmetic Licensed Products in excess * for the remainder of
such calendar year only shall be * .

         6.3 Reports. After the first commercial sale of a Licensed Product
manufactured by or on behalf of Collagen, Collagen shall make quarterly written
reports to Cosmederm within *, stating in reasonably specific detail, on a
country-by-country basis, (i) the number of units of each Licensed Product
directly or indirectly sold by Collagen, Affiliates or sublicensed
subdistributors during the reporting period and the calculation of Net Sales
from such gross sales, (ii) the royalties payable under this Agreement on such
sales of units of each Licensed Product during the reporting period, (iii) the
exchange rates used in converting foreign currencies to United States dollars in
the calculation of such royalties, and (iv) the withholding taxes, if any,
required by law to be deducted from such royalties. With respect to royalties
payable on sales of units of the Licensed Products invoiced in United States
dollars, the gross sales, Net Sales, and royalties payable to Cosmederm shall be
expressed in United States dollars. With respect to royalties payable on sales
of units of the Licensed Products invoiced in a currency other than United
States dollars, the gross sales, Net Sales and amounts payable to Cosmederm
shall be expressed in the domestic currency of the country in which the sale was
together with the United States dollar equivalent of the royalty payable,
calculated using the average of the buying and selling exchange rates quoted by
Bank of America (San Francisco) at the close of business on the last banking day
of the calendar quarter prior to the date of payment.

<PAGE>   8

         6.4 Royalty Payments. Concurrently with the making of each such report,
Collagen shall pay to Cosmederm the royalty payments due under Section 6.1 on
sales of units of the Licensed Products during the quarter covered by such
report. All payments shall be in United States dollars.

         6.5 One Royalty. For purposes of this Agreement, each Licensed Product
sold hereunder shall be sold only once in a royalty-generating transaction, and
subsequent sales or transfers of such Licensed Product shall not result in any
additional royalty payment hereunder.

         6.6 Taxes. In the event that Collagen is required by law to deduct
withholding taxes from royalty payments which would otherwise be payable to
Cosmederm hereunder, Collagen will promptly provide Cosmederm with all
documentation reasonably required by Cosmederm to obtain a corresponding
reduction in Cosmederm's United States taxes.

         6.7 Audits. Collagen shall keep, and cause each Affiliate and each
sublicensed subdistributor to keep, true and accurate books of account and
records in sufficient detail to properly determine the royalties payable to
Cosmederm in connection with the distribution of the Licensed Products. Collagen
shall keep, and cause each Affiliate and each sublicensed subdistributor to
keep, such books and records for at least three (3) years following the end of
the calendar quarter to which they pertain, and shall make available, and cause
each Affiliate and each sublicensed subdistributor to make available, such books
and records for inspection during such three (3) year period by a certified
public accountant retained by Cosmederm for such purpose, solely for the purpose
of verifying Cosmederm's royalty payments hereunder. Such inspections may be
made no more than once in any twelve (12) month period, at reasonable times
mutually agreed upon by the parties after at least five (5) days written notice
to Collagen. The certified public accountant shall execute a confidentiality
agreement reasonably acceptable to Collagen prior to commencing any such
inspection. All such inspections conducted shall be at Cosmederm's expense,
unless an underpayment exceeding * of the amount payable for the period covered
by the inspection is established in the course of any such inspection, whereupon
all costs relating to such inspection shall be paid by Collagen.

7.0      Rights of First Offer.

         7.1 Cosmederm shall fully disclose to Collagen (to the greatest extent
that Cosmederm is not contractually prohibited from doing so) in writing any
additional human cosmetic and dermatologic products, including, but not limited
to, acne products, therapeutic emollients and moisturizers, therapeutic
shampoos, skin treatment products and pigment lightening creams which
incorporate the Licensed Technology, Cosmederm contemplates developing with the
Licensed Technology during the effective term of this Agreement. Collagen shall
have * after Collagen's receipt of such disclosure to determine whether or not
Collagen is interested in pursuing such new product

*Confidential treatment requested.


                                      -8-

opportunity within the Collagen Field and to so inform Cosmederm. In the event
that Collagen does not within * inform Cosmederm in writing that Collagen is
interested in pursuing any such proposed product opportunity, then Cosmederm
shall be able to pursue such new product opportunity by itself or with any third
party. If Collagen informs Cosmederm in writing that Collagen is interested in
pursuing such new product opportunity, the parties shall enter into good faith
and exclusive negotiations for up to * regarding the possible terms of an
agreement, including but not limited to the supply and transfer pricing terms,
pursuant to which Cosmederm and Collagen may jointly develop, manufacture,
and/or sell such new product. In the event the parties do not reach such an
agreement within such * , then Cosmederm shall be able to pursue such new
product opportunity with any third party (or by itself), but under terms and
conditions no more favorable than those finally offered to Collagen.

         7.2 Collagen shall fully disclose to Cosmederm in writing any
additional cosmetic and dermatologic products for the Collagen Field, including,
but not limited to, acne products, therapeutic emollients and moisturizers,
therapeutic shampoos, skin treatment products and pigment lightening creams,
Collagen desires to develop with the Licensed Technology during the term of this
Agreement. Cosmederm agrees to negotiate with Collagen exclusively and in good
faith regarding the joint development of such product, and to use Cosmederm's
best efforts to conclude an agreement between the parties pursuant to which
Cosmederm and Collagen may jointly develop, Collagen and/or Cosmederm may
manufacture, and Collagen may sell such new product. In the event that Collagen
does manufacture, directly or indirectly, any such additional Licensed
Product(s) independently of Cosmederm, Cosmederm shall cooperate fully and
diligently with Collagen's efforts to manufacture and commercialize such new
product(s). For avoidance of doubt, (i) Collagen shall have the right, but not
the obligation, to manufacture (or have manufactured) any Licensed Product
proposed by Collagen and developed by the parties under this Section 7.2 in the
event that the parties do not agree upon manufacturing terms pursuant to which
Cosmederm would manufacture such Licensed Product, and (ii) Cosmederm shall be
entitled to receive the royalty called for in Section 6.1 on each and every
Licensed Product manufactured and sold by Collagen, Affiliates or sublicensees
under this Agreement. If the parties are unable to mutually agree upon the terms
and conditions of a development agreement, neither party shall develop,
manufacture or sell such product.

8.0      Licensed Product Development

         8.1 Cosmederm shall be responsible for * of all research, development,
manufacturing and marketing claims support costs of the Licensed Products
specified in Exhibit A. Collagen is responsible for * of all other marketing,
sales and distribution costs for the Licensed Products specified in Exhibit A,
including, but not limited to, consumer acceptance studies, focus groups, and
test market studies. The parties may mutually agree upon the allocation of costs
related to the joint development of any additional Licensed Product(s) proposed
by either Collagen or Cosmederm pursuant to Sections 7.1 and 7.2.

9.0      Indemnities.

         9.1 Collagen's Indemnity. Cosmederm shall defend, indemnify and hold
Collagen harmless against all damages, costs (including reasonable attorneys'
fees) or other liability, actually incurred by Collagen, or assessed against
Collagen by a court, arbitrator or government agency of competent jurisdiction,
arising from any claim, suit or proceeding based on a third party claim of
intellectual property infringement related to the Licensed Technology or product

                                      -9-

liability (to the extent such claim is related to Cosmederm's supplying Licensed
Product(s) not meeting the Acceptance Specifications, and/or if such product
liability arises from or is related to the product design of Licensed Products
designed solely by Cosmederm) brought individually or severally against Collagen
as a result of Collagen's distribution of Licensed Products. Collagen shall
provide Cosmederm with prompt notification of any such claim, suit or
proceeding, and shall provide Cosmederm with reasonable assistance, at
Cosmederm's expense, in connection with the defense or settlement thereof.
Cosmederm shall have sole control of the defense or settlement of any such
claim, suit or proceeding, subject to Collagen's right to step in and assume
control of such defense in the event Cosmederm refuses to conduct such defense.
No settlement shall be binding on Collagen without Collagen's written consent.
However, should Collagen refuse to consent to a settlement arranged by
Cosmederm, then Cosmederm may (but shall not be obligated to) pay Collagen the
indicated settlement amount; if Cosmederm does so, Cosmederm shall thereupon be
relieved of all further responsibility to Collagen under this Section 9.1.

         9.2 Cosmederm's Indemnity. Collagen shall defend, indemnify and hold
Cosmederm harmless against all damages, costs (including reasonable attorneys'
fees) or other liability, actually incurred by Cosmederm, or assessed against
Cosmederm by a court arbitrator or government agency of competent jurisdiction,
arising from any claim, suit or proceeding brought individually or severally
against Cosmederm to the extent such claim, suit or proceeding is the result of
Licensed Product(s) manufactured by Collagen (or Collagen's manufacturing
sublicensees) which fail to meet the Acceptance Specifications, and/or arises
from or is related to marketing claims made by Collagen and not approved by
Cosmederm and/or product design of Licensed Products designed solely by
Collagen. Cosmederm shall provide Collagen with prompt notification of any such
claim, suit or proceeding, and shall provide Collagen with reasonable
assistance, at Collagen's expense, in connection with the defense or settlement
thereof. Collagen shall have sole control of the defense or settlement of any
such claim, suit or proceeding, subject to Cosmederm's right to step in and
assume control of such defense in the event Collagen refuses to conduct such
defense. No settlement shall be binding on Cosmederm without Cosmederm's written
consent. However, should Cosmederm refuse to consent to a settlement arranged by
Collagen, then Collagen may (but shall not be obligated to) pay Cosmederm the
indicated settlement amount; if Collagen does so, Collagen shall thereupon be
relieved of all further responsibility to Cosmederm under this Section 9.2.
