                                    offer from a third party expressing its
                                    interest to acquire LipoMatrix at a
                                    substantial premium in excess of $1.25 per

                                    dividends), provided, if Collagen so
                                    requests, such offer is substantiated by an
                                    investment banker,

the Board of Directors of LipoMatrix (with the representatives of Collagen
abstaining) may direct LipoMatrix to offer ("LipoMatrix Offer") to purchase all
outstanding shares, options or other rights to equity of LipoMatrix held by
Collagen ("Collagen Shares").

                 (b)      The Board of Directors of Collagen shall have thirty 
(30) days after receipt of the LipoMatrix Offer and shall be obligated within 
such thirty (30)-day period either

                          (i)     to accept the LipoMatrix Offer, or

                                  LipoMatrix Offer ("Collagen Purchase Option").

         In the event Collagen has accepted (or is deemed to have accepted) the
LipoMatrix Offer, Collagen shall sell all the Collagen Shares in accordance with
the LipoMatrix Offer. If Collagen does not exercise the Collagen Purchase Option
within such thirty (30)-day period, Collagen will be deemed to have accepted the
LipoMatrix Offer.

shall be obligated to sell in accordance with the Collagen Purchase Option.

         The election by Collagen to purchase or sell shall be irrevocable and
unconditional once made. The closing of the purchase by (i) LipoMatrix of
Collagen Shares or (ii) Collagen of LipoMatrix shall take place within ninety

Collagen Purchase Option, (ii) to agree to the ability of the LipoMatrix Board

parties shall take all steps reasonably necessary to facilitate the acquisition
of shares, options or warrants pursuant to such Collagen Purchase Option or
LipoMatrix Offer. 

7.       OWNERSHIP OF INVENTIONS.

         7.1     Rights. Inventions shall belong to the inventing party;
provided, however, if such invention is jointly developed by the parties, the
invention shall be jointly owned with each party having an equal and undivided
one-half co-ownership interest therein and the unrestricted right to use and
license others to make, have made, use, sell and otherwise distribute such
product. In connection therewith, each of LipoMatrix and Collagen may make, have

reasonable attorney's fees) will be apportioned between LipoMatrix and Collagen
according to the contribution of either party to the damage and if such
allocation is not mutually agreed then it will be determined by mandatory
arbitration as provided in Section 14.3. The apportionment of damages as
aforesaid will apply with respect to final judgments of a court of competent
jurisdiction from which no appeal is or can be taken as well as settlements made

however, either party may assign this Agreement to any wholly-owned subsidiary
of such party or to any successor to its business by merger, sale of assets or
sale of stock, provided that such successor agrees in writing to be bound by the
terms of this Agreement and a copy of such agreement is delivered to the other

assigns.

Commercial Sales of the Products in the Territory as soon as practicable after

organization of a part-time or full-time Product specialist by LipoMatrix, at
LipoMatrix's sole option and expense, for purposes of providing marketing and

functional capability and other features of the Products, with a view to

written communications from its customers with respect to the use of its
Products, suggestions for modifications or improvement to the Products,
reliability of Products, performance of the Products, compliance with
specifications, and other pertinent information.

         G.      REGISTRY INFORMATION. On a monthly basis, Distributor will 
provide to LipoMatrix a report which will provide such information defined by
LipoMatrix as necessary for maintenance of a registry of implants, including but
not limited to, the transponder numbers for those Products shipped to customers
or otherwise disposed of, including the transponder number and the customer

Products equivalent to three (3) months of forecast sales provided the Products
have a stated shelf life of at least twenty-four (24) months.

secure and well organized facility. In addition, such storage space will comply
with environmental requirements, including temperature or other requirements,
set forth on the labeling of the Products, or other reasonable requirements
notified from time to time by LipoMatrix to Distributor.

                 Distributor will maintain records of the Products to enable
traceability of Products. Distributor will use an effective materials management
system for tracking its inventory and shipments of Products to its customers.

         I.      RISK MANAGEMENT PROGRAM. Distributor recognizes that LipoMatrix
maintains an active program of risk management as set out in Exhibits A and B
attached to this Agreement (the "Risk Management Program"). The Risk Management
Program may be changed by mutual agreement. Distributor agrees to comply with
the Risk Management Program and to use its best efforts to assure compliance by
Distributor's customers.

make any representations, warranties or guarantees with respect to the
specifications, features or capabilities of the Products that are not consistent
with LipoMatrix's documentation accompanying the Products or LipoMatrix's
literature describing the Products, including LipoMatrix's standard warranty and
disclaimers. Distributor shall not make any commitments or comments to its

         M.      EXTENDED WARRANTY. In addition, an extended warranty will be

payments, and the interest earned on them until expenditure, are intended to be
expended on mutually agreed research, development, clinical and manufacturing
programs for breast implant products and other products intended for use in
cosmetic or reconstructive breast surgery, and if such funding is not expended,
the funds shall revert to Distributor. LipoMatrix shall have full ownership of
the results of such programs; provided, however, if Distributor and its
affiliates beneficially own less than twenty percent (20%) of LipoMatrix,

products incorporating the results of such programs outside the Territory and
other territories where Distributor and its affiliates are selling Products.
Distributor shall have the exclusive right to market in the Territory all
products developed with any use of such funds and any such product shall be

terms will revert to payment by irrevocable letter of credit (or equivalent
satisfactory to LipoMatrix) payable against shipping documents. Accounts past
due will be subject to a monthly service charge of one and one-half percent
(1.5%) of unpaid sum, but in no event to exceed the maximum allowable by law.

may also decline to make further shipments until all above indebtedness is paid,
and/or alternatively may decline to make further deliveries except for cash in
advance of shipment or letter of credit acceptable to LipoMatrix.

from the purchase quota for such Ordering Year as set forth in Section III.B.1.

                 Distributor's purchase orders hereunder shall be governed by
the terms and conditions of this Agreement. Nothing contained in any purchase
order shall in any way modify or add any terms or conditions of sale.

LipoMatrix. A "reschedule" is defined as changing all or any portion of those
Products scheduled for shipment on any ship date by moving the ship date later
in time. Distributor shall have a right to cancel or reschedule any order for
later shipment provided such request is received by LipoMatrix at least thirty

Program (see Section III.A.3.b) is an essential element of this Agreement.
Failure by either party to adhere to its provisions or to use best efforts to
implement it, may be used as grounds for termination of this Agreement for cause
under this Section.

                 In the event of a substantial change in ownership of
Distributor, or the continued failure by Distributor to meet the purchase quotas
as specified in Section III.B.1, LipoMatrix shall have the right to terminate
this Agreement upon thirty (30) days written notice.

                 In the event that LipoMatrix is acquired by a third party,
LipoMatrix shall have the right to terminate this Agreement upon thirty (30)
days written notice.

                 Either party shall have the right to terminate this Agreement,
by written notice taking immediate effect, if the other party becomes insolvent,

payment obligation which accrued prior to such termination.

         D.      CANCELLATION AND REPURCHASE OPTIONS. Upon expiration or 
termination of this Agreement, any or all unfilled orders shall be cancelled.
LipoMatrix reserves the right at its sole option to repurchase from Distributor

Products, Distributor shall have the right to continue to sell its existing
inventory of such Products for a reasonable period following such expiration or
termination.

         E.      RETURN OF MATERIALS.  Upon expiration or termination of this

Distributor as a result of such claim and any payments made in settlement of
such claim, provided that Distributor gives LipoMatrix: (a) prompt written
notice of such suit; (b) full control over the defense or settlement thereof;
and (c) all reasonable information and assistance (at LipoMatrix's expense
excluding time spent by employees or consultants of the Distributor) to handle
the defense and settlement thereof.

         If the Products, or any part thereof, are, or in the opinion of
LipoMatrix may become, the subject of any claim, suit or proceeding for
infringement of any patent or trademark, or in the event of any adjudication
that the Products, or any part thereof, infringe any patent or trademark, or if
the sale or use of Products, or any part thereof, is enjoined, LipoMatrix may,
at its option and expense: (a) procure for Distributor and its customers the
right under such patent or trademark to use or sell as appropriate the Products
or such part thereof; or (b) replace the Products, or part thereof, with other
suitable Products or parts; or (c) suitably modify the Products or part thereof,
or (d) if none of the foregoing are commercially practicable, refund the amounts
paid therefore by Distributor, and recover possession of such Products.
LipoMatrix shall not be liable for any costs or expenses incurred without its
prior written authorization.

         Notwithstanding the provisions of the preceding paragraphs, LipoMatrix
shall not be liable to Distributor or its customers for: (a) infringement of
patent claims covering the usage of LipoMatrix Products in a manner not intended
under this Agreement; (b) any trademark infringements involving any marking or
branding applied by LipoMatrix or involving any marking or branding applied at
the request of Distributor, except if such marking or branding is owned by
LipoMatrix; (c) the modification of Products, or any part thereof, unless such
modification was made by LipoMatrix; or (d) the combination, operation or use of
the Product with other products not furnished by LipoMatrix to the extent such
claim would not have arisen had such combination, operation or use not occurred.

         THE FOREGOING PROVISIONS OF THIS SECTION VII STATE THE ENTIRE LIABILITY
AND OBLIGATIONS OF LIPOMATRIX, AND THE EXCLUSIVE REMEDIES OF DISTRIBUTOR AND ITS
CUSTOMERS WITH RESPECT TO ANY ALLEGED INFRINGEMENT OF PATENTS, COPYRIGHTS,
TRADEMARKS, OR OTHER INTELLECTUAL PROPERTY RIGHTS, BY THE PRODUCTS OR ANY PART
THEREOF.

VIII.    PRODUCT LIABILITY

         A.      INDEMNITY BY DISTRIBUTOR. Distributor shall indemnify and hold
LipoMatrix harmless from and against any and all liability, damage, loss, cost,
expense (including reasonable attorney's fees), regulatory penalties and
enforcement actions resulting from any claims made or suits brought against
LipoMatrix, its employees, directors and customers which arise or result solely
from Distributor's marketing, distribution, handling and shipping of the
LipoMatrix Products, or from Distributor's negligence or willful misconduct.
LipoMatrix shall promptly notify Distributor of any such claim or suit and shall
permit Distributor at Distributor's cost and expense, to handle and control such
claim or suit.

         B.      INDEMNITY BY LIPOMATRIX. LipoMatrix shall indemnify and hold
Distributor harmless from and against any and all liability, damage, loss, cost
or expense (including reasonable attorney's fees) resulting from any claims made
or suits brought against Distributor, its employees, directors and customers
which arise or result solely from LipoMatrix's design, handling and shipping of
the LipoMatrix Products, or failure to manufacture the LipoMatrix Products in
accordance with agreed upon specifications, FDA Good Manufacturing Practices or
other applicable standards for medical device manufacturers, or from negligence
or willful misconduct. Distributor shall promptly notify LipoMatrix of any such
claim or suit and shall permit LipoMatrix at LipoMatrix's cost and expense, to
handle and control such claim or suit.

         C.      APPORTIONMENT OF DAMAGES.  In the event that any liability, 
damage, loss, cost or expense (including reasonable attorney's fees) as
aforesaid cannot be established (with respect to final judgments of a court of
competent jurisdiction from which no appeal is or can be taken as well as
settlements made prior to, during or following termination of litigation to
which the parties have expressly agreed in writing) to have resulted solely from
the actions or failures to act of LipoMatrix or Distributor or their affiliates,
responsibility for payment of such liability, damage, loss, cost or expense
(including reasonable attorney's fees) will be apportioned between LipoMatrix
and Distributor according to the contribution of either party to the damage; and
if such allocation is not mutually agreed, then it will be determined by
mandatory binding arbitration.

         D.      PRODUCT LIABILITY INSURANCE. LipoMatrix shall use its 
reasonable commercial efforts to secure product liability insurance in the
amount of five million dollars ($5,000,000), to the extent this is available on
commercially reasonable terms. LipoMatrix shall have Distributor named as an
additional insured on its product liability insurance policy. If LipoMatrix is
unable to secure or maintain such insurance, Distributor may terminate this
Agreement. The parties agree to review the possibility of increasing the amount
of such insurance if increases in sales so warrant.

IX.      LIMITATION OF LIABILITY

         IN NO EVENT, WHETHER THE CAUSE OF ACTION BE BASED IN CONTRACT OR TORT
(INCLUDING NEGLIGENCE) OR ANY OTHER LEGAL OR EQUITABLE THEORY SHALL EITHER PARTY
BE LIABLE FOR INCIDENTAL, CONSEQUENTIAL, INDIRECT, SPECIAL OR PUNITIVE DAMAGE OF
ANY KIND, OR FOR LOSS OF REVENUE, LOSS OF BUSINESS OR OTHER FINANCIAL LOSS
ARISING OUT OF OR IN CONNECTION WITH THE SALE, USE, PERFORMANCE, FAILURE OR
INTERRUPTIONS OF ITS PRODUCTS. NOTWITHSTANDING ANY OTHER PROVISION OF THIS
AGREEMENT, LIPOMATRIX'S MAXIMUM LIABILITY FOR DAMAGES HEREUNDER SHALL NOT EXCEED
THE PURCHASE PRICE OF THE PRODUCTS PURCHASED DURING THE TERM OF THIS AGREEMENT.
THE FOREGOING LIMITATIONS SHALL NOT AFFECT EITHER PARTY'S DUTY TO INDEMNIFY THE
OTHER PARTY FOR THIRD-PARTY SUITS FOR SUCH DAMAGES, AS SET FORTH IN SECTIONS VII
AND VIII.

         THE DISCLAIMER OF LIABILITY FOR DAMAGES WILL NOT BE AFFECTED IF ANY
REMEDY PROVIDED HEREUNDER SHALL FAIL OF ITS ESSENTIAL PURPOSE. DISTRIBUTOR HAS
ACCEPTED THE DISCLAIMER OF LIABILITY FOR DAMAGES AS PART OF A BARGAIN TO LOWER
THE PRICE OF THE PRODUCTS AND UNDERSTANDS THAT THE PRICE OF THE PRODUCTS WOULD
BE HIGHER IF LIPOMATRIX WERE REQUIRED TO BEAR ADDITIONAL LIABILITY FOR DAMAGES.

X.       NO RIGHT TO MANUFACTURE OR COPY

         The Products are offered for sale and are sold by LipoMatrix subject in
every case to the condition that such sale does not convey or license to
Distributor, expressly or by implication, the right to manufacture, duplicate or
otherwise copy or reproduce any of the Products. Distributor shall take
appropriate steps with customers, as mutually agreed, to inform them of, and
both parties shall, as mutually agreed, assist each other in assuring compliance

                 Each party agrees that it shall not use in any way for its own
account or the account of any third party, nor disclose to any third party, any
such confidential information which is revealed to it by the other party. The
receiving party shall take every reasonable precaution to protect the
confidentiality of such information, which in no event shall be less than the
efforts exercised by such party with respect to its own confidential business
information. Distributor and LipoMatrix shall advise each other in the event
that either party considers particular information or materials to be
confidential. Distributor shall not publish any technical description of the
Products beyond the description published by LipoMatrix.

                 In the event of expiration or earlier termination of this 
Agreement, there shall be no use or disclosure by Distributor or LipoMatrix of
any confidential information, and Distributor shall not manufacture, or have
manufactured, devices, components or assemblies utilizing any of LipoMatrix's

                             RISK MANAGEMENT PROGRAM

                                   April, 1995

The following is a discussion of the LipoMatrix, Incorporated Risk Management
Program for the company's TRILUCENT(TM) Breast Implant.

The strong linkage and trail of mutual accountability among manufacturer,
distributor, surgeon and consumer as a result of full employment of the measures
described in this Risk Management Program provides benefits for all parties. The
manufacturer is responsible and accountable for its products, and remains
informed of the performance of the product in the marketplace. The distributor
is in the communication loop in providing tools to the surgeon as a condition of
availability of TRILUCENT. The surgeon is kept fully aware of product benefits
and risks, and is provided with educational tools to facilitate communication
with his/her patient. The patient-consumer is responsible, having received
adequate information, for making an enlightened decision based on personal
choice and full understanding of risk vs. benefit - while also taking comfort in
knowing that a degree of protection from the financial consequences of an
adverse event is provided.

While there is no way to eliminate loss exposure, a strong risk management
program (such as detailed here) may reduce loss exposure and enhance physician
and patient satisfaction through better information.

PRODUCT OVERVIEW

The basic building block of a risk management program is a product that is
appropriately designed and tested. The TRILUCENT implant represents an entirely
new technology in the field of breast implants. This product addresses and
provides:

     -   Radiolucency - a neutral triglyceride (lipid) filler designed to 
         facilitate detection of breast cancer by mammography.

     -   Biocompatibility - metabolism and excretion of the triglyceride
         filler in case of a leak or rupture with minimal or no local or
         systemic consequences.

     -   Resistance to infection - the triglyceride filler is 
         bactericidal/fungicidal for a broad spectrum of organisms.

     -   Composite silicone shell - engineered for strength, abrasion
         resistance, integrity, and biocompatibility.

                        CONFIDENTIAL TREATMENT REQUESTED

     -   Integrated and innovative delivery system - to reduce handling
         errors by the surgeon.

     -   Transponder microchip ID system - designed to allow
         non-invasive device identification at any time, thus facilitating
         device registry, tracking, adverse events reporting and post-market
         surveillance.

LipoMatrix has compiled nearly eight years of pre-clinical studies regarding the
TRILUCENT technology and product. LipoMatrix-sponsored research continues
in-house and at several major U.S. Universities.

LipoMatrix has now compiled a greater than 100-patient experience with up to 12
month follow-up as part of an ongoing multinational, multicenter European
clinical trial of TRILUCENT. The goal is to complete a formal analysis on
approximately 300 subjects followed for one year (minimum) as part of a clinical
database that will continue to accrue following product launch. LipoMatrix
believes that no other breast implant company has sponsored such a comprehensive
prospective study.

On July 15, 1994, after nearly two years of review of pre-clinical data, the
U.S. FDA gave permission to LipoMatrix to conduct IDE-based clinical trials of
its TRILUCENT product in the USA -- the first breast implant in history to be
granted such permission.  This trial commenced in December, 1994.

RISK MANAGEMENT STRATEGY

LipoMatrix has developed a risk management program, the elements of which,
together with a brief description, are as follows:

                        CONFIDENTIAL TREATMENT REQUESTED

PRODUCT LIABILITY INSURANCE

While the proactive risk management approaches described above are critical to
minimizing the risks for all parties, it is also appropriate to maintain product
liability insurance for those cases where claims do occur. As well as providing
protection for the manufacturer's assets, such insurance provides a level of
assurance to surgeons and patients that there is an additional element of
financial support for the TRILUCENT.

There is no guarantee that product liability insurance will be available on
commercially feasible terms. However, LipoMatrix will try to secure such
insurance to the extent commercially reasonable.


                                       6
<PAGE>   37
PRODUCT WARRANTY - "PATIENT PROTECTION PLAN"

The "PATIENT PROTECTION PLAN" currently features an Extended Warranty provided
as a matter of course by LipoMatrix through its contracts with its distributors.

EXTENDED WARRANTY
This warranty provides that LipoMatrix will supply a free replacement implant of
the same size in case of implant failure within 5 years following initial
successful implantation. Failure is defined as loss of volume, i.e. deflation,
by implant leak or rupture for whatever reason, except medical intervention,
manipulation, or gross negligence or willful misconduct of the patient or
physician.

The only preconditions for receiving this warranty coverage are (i) execution of
the Patient Advisory and Consent document by the patient and surgeon, (ii) entry
by the patient into the Registry, (iii) submission to LipoMatrix of appropriate
documentation of the clinical condition including an attestation by the surgeon
that the failure was not the result of medical intervention or manipulation, and
(iv) that the explanted implant has been returned to LipoMatrix for failure
analysis.

CAVEAT

Notwithstanding this Risk Management Program, there is no assurance that a
patient or other party will not sue or seek other legal remedies and that the
applicable judicial process will not award excessive damages or remedies.

                        THE TRILUCENT(TM) BREAST IMPLANT
                       -- PATIENT ADVISORY AND CONSENT --

PART I:
IMPORTANT INFORMATION ABOUT BREAST IMPLANTS

As manufacturer of the TRILUCENT(TM) Breast Implant, LipoMatrix, Inc., has
carefully assessed potential risk factors associated with breast implants and
has taken precautions in the manufacture of our product. These factors include

     - compatibility of implant materials with the body and its systems 
     - need for radiolucency of the implant for better mammography 
     - need for long-term identification of the implant after it has been 
       inserted.

A most important aspect to understand is that breast implants, like any part of
your body, will age. A breast implant is classified as a medical device, and
like any man-made object, may eventually wear out despite the very best
materials and manufacturing techniques. Should that ever happen, it is important
that no harm come to you. You and your surgeon should discuss the life
expectancy of your implant and what to expect if your implant should need
replacement.

To further assure you of our commitment to your well-being, LipoMatrix provides
a Patient Protection Plan, consisting of a Registry and a Warranty, for
recipients of the TRILUCENT Breast Implant.


                                                                    Page 1 of 14
<PAGE>   40
PART II:
COMMON RISK FACTORS OF BREAST IMPLANTS -- AND HOW THE TRILUCENT(TM) BREAST 
IMPLANT DIFFERS

BREAST CANCER DETECTION AND INTERFERENCE WITH MAMMOGRAPHY

Mammography (breast X-ray) is the world-wide standard for early breast cancer
detection. But breast implants, as they were developed in the mid-1960's,
interfere with the ability to observe the breast during mammography, because
most breast implants contain fillers which are denser than fat. In 1987, several
female radiologists, concerned about women's needs, sought to find a breast
implant that would allow penetration by mammographic X-rays. The TRILUCENT
implant is the result.

Human fat is the lucent "window" through which the glandular tissue is observed
during x-ray and mammography. A "Z number" determines a substance's potential to
interfere with mammography. Human breast fat has a Z number of about 6.0. An
implant filler with a Z number of about 6.0 is a key to facilitating
mammography.

The TRILUCENT Breast Implant is different from other implants because it is
filled with naturally occurring oils and fats from a soybean source -- called
"triglycerides" -- the same oils found in human breast fat. Since human fat and
the TRILUCENT Breast Implant triglyceride filler have the same X-ray density
(both means that breast fat and the contents of the TRILUCENT implant both allow
penetration by mammography X-rays. These observations have been confirmed by
numerous studies.

Detection of breast cancer depends on many factors, only one of which is the
implant's radiolucency. There may be difficulty in detecting a small cancer with
any implant. You must discuss this important subject with your surgeon.

LEAKAGE:  WHAT HAPPENS WHEN AN IMPLANT FAILS

          Filler in Contact with Tissue
Breast implants may leak or suffer disruption of the shell integrity from wear,
defect or trauma. Sometimes, the cause is not apparent. However, there are
several reasons why a breast implant may fail. One is a simple wearing out of
the silicone


                                                                    Page 2 of 14
<PAGE>   41
shell from normal wrinkling and friction. Another can be due to an accident,
like a fall, or a severe blow to the chest, as in an automobile accident, which
may cause the implant to rupture. Rarely, damage to an implant may occur during
the handling of it at the time of surgery, or in the treatment of a capsular
contracture (scar around the implant ) by capsulotomy. In any of these
instances, the contents of the implant -- the filler material -- may leak into
the body.

Whether leakage is potentially harmful to the body has to do with the type of
filler material that the implant contains. The body can not completely rid
itself of some older implant fillers. Those fillers, when they leak, may cause
scars and inflammation and may, in some instances, be mistaken for a breast
tumor. Filler which has leaked from that type breast implant may require
surgical removal.

If the salt-water (saline) filler used in some implants was not sterile or if
bacteria or fungus inadvertently entered the filler solution during the
operating procedure, the bacteria or fungus might grow inside the implant. If
contaminated saline should enter the body, the effects may be dangerous.

The TRILUCENT Breast Implant is filled with natural triglycerides with the same
chemical composition as the triglycerides of normal human fat. And the same
triglycerides used in TRILUCENT (USP soy oil) have been used medically for over
40 years as intravenous nutrition for seriously ill patients and premature
infants. Studies indicate that triglycerides will not support bacterial or
fungal growth, and will simply be absorbed and digested by the body's natural
mechanisms in case of leakage -- whatever the cause. In some cases, a mild,
localized inflammation or redness may temporarily occur. Theoretically, a small
collection or "cyst" might remain which your doctor could drain.

SHELL FORMULATION TO RESIST WEAR
Silicone shells are used in all breast implants because this solid form
of silicone is strong, elastic and will stretch with breast movement. The
silicone shell used in the TRILUCENT Breast Implant is specially formulated to
retain its structural strength over time. This shell design, coupled with the
triglyceride filler, drastically reduces the possibility of implant leakage from
shell wear and friction. The specially formulated shell also virtually
eliminates silicone residuals from entering the tissues.


                                                                    Page 3 of 14
<PAGE>   42
THE VIGILANCE(TM) IDENTIFICATION SYSTEM AND THE IMPORTANCE OF IMPLANT 
IDENTIFICATION
Because any implantable device may cause concern or need to be checked at some
point, it is important to be able to identify the implant, its origin and its
history, even years after surgery.

LipoMatrix, Inc., has developed the Vigilance(TM) implant identification system
that allows privacy and confidentiality while enabling future identification of
your TRILUCENT implant should it become necessary. The transponder microchip,
which contains a unique code number for the implant, generates no power or
radiation. It is laminated within the breast implant shell. Data associated with
this unique identification system can only be accessed with your
permission. The transponder will not interfere with routine tests or future
medical procedures that you may have. Should it become necessary to identify
your breast implant, even if your records have been lost or if you have
forgotten important details about the implantation surgery or the device itself,
a simple hand-held reading device will allow your surgeon to access information
about your implant. This feature assures you that LipoMatrix always acknowledges
responsibility for the implants it manufactures. No other breast implant has
this feature.

CAPSULAR CONTRACTURE/CALCIFICATION
The most common problem with any type of breast implant is a slowly developing
firmness called "capsular contracture." The body's natural response creates a
layer of scar tissue ("capsule") around the entire surface of any type of
implant. Ideally, the scar capsule will remain thin and pliable. However, if the
scar tissue shrinks and thickens (contracts), it may compress the implant,
making the breast round and firm, sometimes tender and immobile. Capsular
contracture can start anytime after surgery, even several years later, most
commonly on one side only. Often, capsular contracture does not occur at all.

Because some form of scar capsule always occurs with a breast implant,
capsular contracture is considered an inherent risk of a breast implant. No one
is sure of the cause, and some women have no scar problems. However, it is
believed that the surgical method -- whether placing the implant under the chest
muscle or above -- as well as the composition and surface treatment of the
shell, can combine to modify the body's response. This is why the TRILUCENT
Breast Implant is available with a new textured shell design which may reduce
scar formation in most applications. Always discuss treatment of capsular
contracture with your surgeon.


                                                                    Page 4 of 14
<PAGE>   43
Any surgery or injury to the breast may produce small spots of calcium which may
be seen on mammography. These deposits may not occur until years after surgery
and occasionally a biopsy may be necessary to confirm that the spots are
harmless.

WRINKLING AND RIPPLING
Any fluid-filled implant (including TRILUCENT) may exhibit some wrinkling of the
implant shell. If breast tissue is very thin, these wrinkles can show as visible
ripples, especially when leaning forward without a brassiere. Wrinkling can also
produce little corners on the implants that can sometimes be felt if the breast
tissue is very thin.

                                       ***

The above discussion reviews common risk factors associated with breast
implants. Some specific features of the TRILUCENT(TM) Breast Implant are
discussed. It is not intended to be an exhaustive review, nor does it provide a
complete representation of the breast surgery itself, which may differ from
patient to patient. Other implants may pose additional risks. You should discuss
all of the information in this booklet, in detail, with your surgeon. Also ask
him or her to discuss the risks of other implants as well as the surgical
procedure with you, so you understand all factors concerning your breast implant
and your surgery -- before the procedure.


                                                                    Page 5 of 14

PART III
RARE OR UNKNOWN RISK FACTORS ASSOCIATED WITH BREAST IMPLANTS

AUTO-IMMUNE AND CONNECTIVE TISSUE DISEASE
A possible connection has been drawn in the medical literature between certain
types of breast implants and auto-immune diseases (connective tissue disorders
such as scleroderma, rheumatoid arthritis, lupus, etc.). These disorders are
rare and an actual cause- and-effect relationship between breast implants and
these diseases has neither been proved nor disproved. Recent studies strongly
suggest no connection.

TRILUCENT implants contain only the solid silicone-rubber of the shell. In
millions of patients with solid silicone-rubber implants (for example, finger
joints), there has been no reported association of these implants with
auto-immune disease.

Fat Emboli Formation (oil droplets in the blood)
Although there is no evidence that fat emboli can occur as a result of
triglycerides being released into the blood in the event of implant rupture,
there is a theoretical risk that this can occur.

POTENTIAL PROBLEMS OF FAT METABOLISM
In the event of TRILUCENT leakage in a normal, healthy individual, the amount of
fat (oil) released is expected to be digested (metabolized) by the body over a
period of several weeks without ill effect. However, if you have a known
cholesterol problem, or other disease of fat metabolism (for example, pathologic
hyperlipemia, lipoid nephrosis, acute pancreatitis with hyperlipidemia, etc.),
it should be discussed thoroughly with your surgeon before opting for a
triglyceride filled breast implant.

BREAST IMPLANTS AND CANCER
There is presently no scientific evidence that links breast implants with
cancer. Recent mass surveys from several sources show only normal and expected
(or even lower than expected) rates of breast cancer in women with breast
implants. Further studies are in progress.

BIRTH DEFECTS
Animal studies conducted to date show no evidence that birth defects are related
or caused by breast implants. However, to rule out that possibility with humans,
further scientific studies are continuing to determine whether breast implants
can be associated with birth defects.


                                                                    Page 6 of 14
<PAGE>   45
BREAST FEEDING
Breast implantation usually does not interfere with breast feeding since the
implant is inserted under -- not in -- the breast tissue. Most women report no
difficulties in nursing after implantation, though some individuals experience
difficulty with breast feeding even without implants. If breast feeding is a
concern of yours, please discuss the issue in detail with your doctor before
surgery.


                                                                    Page 7 of 14
<PAGE>   46
PART IV:
SURGICAL RISKS AND COMPLICATIONS ASSOCIATED WITH BREAST IMPLANTATION

BLEEDING AND HEMATOMA
Any operation carries the risk of bleeding or hematoma (collection of congealed
blood in the tissues). Active or sudden bleeding after implant surgery is
unusual, but can be controlled and corrected by your surgeon. Small hematomas
will be absorbed by your body like any bruise, but a large one may have to be
drained to permit proper healing. Sometimes, hematoma may contribute to the scar
(capsule) around the breast implant.

SEROMA
Seroma is a collection of fluid around the implant or in the incision space as a
result of tissue irritation. Seromas seldom cause a long-term problem, but
occasionally require drainage.

INFECTION
Infection -- indicated by swelling, tenderness, pain and fever -- may occur in
the immediate post-operative period after any type of surgery. Infection
is rare after breast implant surgery and is usually treated by antibiotics; but
in severe cases, drainage and implant removal may be required.

CHANGES IN NIPPLE AND BREAST SENSATION
Any breast surgery, including biopsy or breast implant surgery, can result in
increased or decreased sensation of the breast and/or the nipple. This change
can vary in degree and is usually temporary. Occasionally, changes in sensation
may be permanent.

INJURY TO THE BREAST IMPLANT
Rarely, the implant may be weakened or torn by certain medical or surgical
interventions. For example, a closed or open capsulotomy in the treatment of
capsular contracture could result in such an implant injury.

COSMETIC COMPLICATIONS
While your surgeon takes every possible precaution, before and during surgery,
to ensure a satisfactory result, there are still factors which may interfere
with a satisfactory appearance of the breast after surgery. The most common
reasons for dissatisfaction after breast implantation are: firmness or
distortion of the breast,


                                                                    Page 8 of 14
<PAGE>   47
implant size, scar location or appearance, implant displacement and asymmetry
(unequal size or shape). Please discuss all these factors with your surgeon
before the operation.

OTHER RISKS
There have been anecdotal reports of rare, isolated or unusual breast implant
problems. Please discuss all potential problems with your doctor before the
surgery.


                                                                    Page 9 of 14

PART V:
THE LIPOMATRIX PATIENT PROTECTION PLAN

LipoMatrix, Inc., is proud of its products -- and we stand behind them. When you
receive a TRILUCENT Breast Implant you can be assured that every effort has been
made to produce a reliable, long-lasting implant. However, no implant can be
guaranteed to last a lifetime. For this reason, LipoMatrix, Inc., offers each
recipient of the TRILUCENT Breast Implant, the Patient Protection Plan.

REGISTRY PARTICIPATION -- THE KEY
For your protection, and to help ensure that information regarding your implant
will be available to any doctor that you may choose in the future, LipoMatrix,
Inc., maintains a Registry for your TRILUCENT Breast Implant(s). Although
participation is optional, it is strongly recommended that you participate in
our Patient Protection Plan. Registry participation entitles you to warranty
protection. (See below.) Benefits you may elect to receive as a member
of the Registry, in addition to the Warranty, include device related updates,
etc. Information recorded in the Registry about your implant and the surgical
procedure will be used by the Company to send patients and their surgeons device
updates, to meet the Company's warranty obligations, for scientific or medical
research purposes, or in connection with national or foreign regulatory or
judicial proceedings.

As the manufacturer of the TRILUCENT Breast Implant, LipoMatrix feels it is our
responsibility to offer you this service. Your participation, however, relies on
you to discuss all aspects of implant identification and registry with your
surgeon. He or she will provide you with the necessary information needed to
join the Registry. In addition, you and your surgeon need to complete the
information required within the Implant Registry and Warranty Pack which is
sealed inside each TRILUCENT Breast Implant package. This Implant Registry and
Warranty Pack will not be available to you until after the surgery. Make
sure your surgeon provides you with the Implant Registry and Warranty
Pack for each TRILUCENT Breast Implant you receive.

THE TRILUCENT(TM) WARRANTY
The Patient Protection Plan features a substantial Warranty against any implicit
defect in the implant. You automatically qualify for this warranty as long as
you and your surgeon have signed the Patient Advisory and Consent document
included at the end of this booklet and you participate in the Implant Registry
for TRILUCENT.


                                                                   Page 10 of 14
<PAGE>   49
The Warranty means that if any TRILUCENT(TM) Breast Implant should fail -- that
is, leak and lose volume, for any reason except medical or surgical manipulation
of the implant (for example, closed or open capsulotomy, or surgical implant
adjustment) -- within five (5) years after implantation, LipoMatrix will
provide a TRILUCENT replacement implant of the same volume without cost to
you or your surgeon.

It is understood that deflation or implant rupture can occur even many years
after surgery. Our obligation within the Warranty shall extend to providing a
replacement implant only as specifically provided for under the terms and
conditions of the Warranty.

You are solely responsible for the choice of your surgeon and LipoMatrix does
not assume any liability whatsoever for any damage caused by acts or omissions
of the surgeon. Furthermore, this warranty is in lieu of and excludes all other
warranties not expressly set forth herein, whether express or implied by
operation of law or otherwise, subject to a mandatory warranty which cannot be
excluded under applicable laws.

The only preconditions for receiving this warranty coverage are (i) the signing
of the Patient Advisory and Consent document, (ii) entering the Registry for
each implant you receive, (iii) having your implant returned to LipoMatrix
should it need to be removed, so that it can be analyzed, and (iv) arranging for
the treating surgeon to send records to LipoMatrix confirming that the cause of
the leakage was not due to medical intervention.

The signature portion of this Patient Advisory and Consent document should be
signed by you and your surgeon after reviewing and discussing all points
covered in this booklet. Also, make sure you ask your surgeon to provide you
with the Implant Registry and Warranty Pack enclosed with each TRILUCENT
Breast Implant so that you may enter the Registry for each implant you
receive.


                                                                   Page 11 of 14

                    A GLOSSARY OF COMMON BREAST IMPLANT TERMS

         TERM                                  DEFINITION
- --------------------------------------------------------------------------------
capsule                          a scar that always forms around any implantable
                                 device placed in the body-including breast 
                                 implants.
- --------------------------------------------------------------------------------
capsular contracture             tightening and thickening of the normal capsule
                                 around an implant-sometimes causing a feeling
                                 of firmness or discomfort. (See "texture.")
- --------------------------------------------------------------------------------
capsulotomy                      procedure for relieving the scar contracture 
                                 around an implant. A closed capsulotomy is an
                                 external force applied by the surgeon to
                                 manually "break" the internal scar. An open
                                 capsulotomy is a surgical means of relieving
                                 scar contracture.

                                 many forms-from liquid to gel to solid.
                                 Silicone is used in solid form in many types of
                                 medical implants because the body tolerates
                                 solid silicone so well.
- --------------------------------------------------------------------------------
silicone-gel implant             a type of breast implant containing a semi-

                        THE TRILUCENT(TM) BREAST IMPLANT
                       -- PATIENT ADVISORY AND CONSENT --

PART I:
IMPORTANT INFORMATION ABOUT BREAST IMPLANTS

As manufacturer of the TRILUCENT(TM) Breast Implant, LipoMatrix, Inc., has
carefully assessed potential risk factors associated with breast implants and
has taken precautions in the manufacture of our product. These factors include
     - compatibility of implant materials with the body and its systems 
     - need for radiolucency of the implant for better mammography 
     - need for long-term identification of the implant after it has been 
       inserted.

A most important aspect to understand is that breast implants, like any part of
your body, will age. A breast implant is classified as a medical device, and
like any man-made object, may eventually wear out despite the very best
materials and manufacturing techniques. Should that ever happen, it is important
that no harm come to you. You and your surgeon should discuss the life
expectancy of your implant and what to expect if your implant should need
replacement.

To further assure you of our commitment to your well-being, LipoMatrix provides
a Patient Protection Plan, consisting of a Registry and a Warranty, for
recipients of the TRILUCENT Breast Implant.

                          STOCKHOLDER OPTION AGREEMENT

         THIS STOCKHOLDER OPTION AGREEMENT is entered into this ____ day of
_______ 1995 among the undersigned stockholders (the "Stockholders") of
LipoMatrix, Inc., a British Virgin Islands corporation ("LipoMatrix") and
Collagen Corporation, a Delaware corporation ("Collagen").

         WHEREAS, Collagen and LipoMatrix have entered into a License, Supply
and Option Agreement dated _________, 1995 (the "Master Agreement"). The Master
Agreement provides that, in certain circumstances, LipoMatrix may offer to
purchase all outstanding shares or warrants of LipoMatrix held by Collagen
("LipoMatrix Offer"). The Board of Directors of Collagen shall be obligated
either to accept such offer or to agree to purchase all shares or warrants of
LipoMatrix at the same price ("Collagen Purchase Option"). If Collagen elects to
purchase LipoMatrix's shares or warrants, LipoMatrix shall be obligated to sell.

         WHEREAS, All present and future holders of more than 5% of the
outstanding voting securities of LipoMatrix shall be obligated to agree to the
above Collagen Purchase Option and to the ability of the LipoMatrix Board of
Directors to trigger the LipoMatrix Offer on their behalf.

         WHEREAS, the Stockholders own those number of shares of Common Stock,
Series A Preferred Stock and Series B Preferred Stock of LipoMatrix ("Shares"),
listed opposite their names on Exhibit A attached hereto; and

         WHEREAS, as a condition to its willingness to enter into the Master
Agreement, Collagen has requested that the Stockholders agree, and the
Stockholders have agreed, severally and not jointly, to grant Collagen an
irrevocable option as set forth herein to purchase up to an aggregate amount of
approximately __________ Shares (subject to adjustment as provided herein);

         NOW, THEREFORE, to induce Collagen to enter into, and in consideration
of it entering into, the Master Agreement, and in consideration of the premises
and the representations, warranties and agreements herein contained, the parties
agree as follows:

         1.      Stockholder Option.

                 (a) Grant of Stockholder Option. Each Stockholder,
severally and not jointly, hereby grants to Collagen an irrevocable option (the
"Stockholder Option", and collectively the "Stockholder Options") to purchase
the number of outstanding shares (as adjusted for stock splits, stock dividends,
or combinations of shares) of Common Stock, Series A Preferred Stock and Series
B Preferred Stock set forth next to such Stockholder's name on Exhibit A
attached hereto (the "Optioned Shares") in the event Collagen has exercised the
Collagen Purchase Option, all in accordance with Section 6 of the Master
Agreement. The parties acknowledge that Collagen may exercise the Collagen
Purchase Option only if LipoMatrix first makes the LipoMatrix Offer to purchase
Collagen's interest in LipoMatrix's equity.

<PAGE>   58
                 (b) Exercise of Option. Provided that Collagen shall
have exercised the Collagen Purchase Option, Collagen may exercise the
Stockholder Options in whole, and not in part, at any time (provided that all
the Stockholder Options must be exercised). In the event that Collagen wishes to
exercise the Stockholder Option, Collagen shall give written notice (the date of
such notice being herein called the "Notice Date") to the Stockholder specifying
the date it will purchase pursuant to such exercise (not later than ten business
days and not earlier than five business days from the Notice Date) for the
closing of such purchase, which closing shall occur in Palo Alto, California or
such other place as the parties may agree. In the event that Collagen exercises
the Stockholder Option, Collagen will promptly offer to purchase all other
outstanding shares, and rights to acquire shares, of LipoMatrix at the same
price and terms as those set forth in the Stockholder Option.

                 (c) Payment of Purchase Price and Delivery of Certificates for
Optioned Shares. At any closing hereunder,

                          (1) against delivery of the certificates and warrants
set forth in (2) below, Collagen will make payment to each Stockholder either in
next day funds by certified or official bank check payable to the order of such
Stockholder, or with a certificate for registered (with the Securities and
Exchange Commission under a Registration Statement) or freely tradable Common
Stock of Collagen, and

                          (2) against such payment, such Stockholder will
deliver to Collagen his certificate or certificates representing the number of
Optioned Shares so purchased, duly endorsed for transfer to Collagen and
instruct LipoMatrix and its transfer agent to deliver to Collagen a certificate
or certificates representing the Optioned Shares, registered in the name of
Collagen, with applicable legends regarding "restricted securities" under the
Securities Act of 1933 and the Rules and Regulations thereunder ("Securities
Act").

         2.      Proxy.

                 (a) Revocation of Prior Proxies. Each Stockholder
hereby revokes any and all previous proxies granted with respect to such
Stockholder's Optioned Shares.

                 (b) Grant of Proxy. By entering into this Agreement,
each Stockholder hereby grants a proxy with respect to such Stockholder's
Optioned Shares appointing Collagen as such Stockholder's attorney-in-fact and
proxy, with full power of substitution, for and in such Stockholder's name, to
vote, express consent or dissent, or otherwise to utilize such voting power in
favor of the acquisition of LipoMatrix by Collagen by merger pursuant to Section
6 of the Master Agreement upon exercise of the Collagen Purchase Option
("Merger") (whether the form of the consideration is cash or stock). Collagen
agrees to execute the proxy granted by each Stockholder by voting in favor of
the Merger pursuant to the Master Agreement. The proxy granted by each
Stockholder pursuant to this Section 2 is irrevocable and is granted in
consideration of Collagen's entering into this Agreement and the Master
Agreement.

        If the Products, or any part thereof, are, or in the opinion of
LipoMatrix may become, the subject of any claim, suit or proceeding for
infringement of any patent or trademark, or in the event of any adjudication
that the Products, or any part thereof, infringe any patent or trademark, or if
the sale or use of Products, or any part thereof, is enjoined, LipoMatrix may,
at its option and expense: (a) procure for Distributor and its customers the
right under such patent or trademark to use or sell as appropriate the Products
or such part thereof; or (b) replace the Products, or part thereof, with other
suitable Products or parts; or (c) suitably modify the Products or part thereof,
or (d) if none of the foregoing are commercially practicable, refund the amounts
paid therefore by Distributor, and recover possession of such Products.
LipoMatrix shall not be liable for any costs or expenses incurred without its
prior written authorization.

        Notwithstanding the provisions of the preceding paragraphs, LipoMatrix
shall not be liable to Distributor or its customers for: (a) infringement of
patent claims covering the usage of LipoMatrix Products in a manner not intended
under this Agreement; (b) any trademark infringe ments involving any marking or
branding applied by LipoMatrix or involving any marking or branding applied at
the request of Distributor, except if such marking or branding is owned by
LipoMatrix; (c) the modification of Products, or any part thereof, unless such
modification was made by LipoMatrix; or (d) the combination, operation or use of
the Product with other products not furnished by LipoMatrix to the extent such
claim would not have arisen had such combination, operation or use not occurred.

        THE FOREGOING PROVISIONS OF THIS SECTION VII STATE THE ENTIRE LIABILITY
AND OBLIGATIONS OF LIPOMATRIX, AND THE EXCLUSIVE REMEDIES OF DISTRIBUTOR AND ITS
CUSTOMERS WITH RESPECT TO ANY ALLEGED IN FRINGEMENT OF PATENTS, COPYRIGHTS,
TRADEMARKS, OR OTHER INTELLEC TUAL PROPERTY RIGHTS, BY THE PRODUCTS OR ANY PART
THEREOF.

VIII.   PRODUCT LIABILITY

        A.     INDEMNITY BY DISTRIBUTOR. Distributor shall indemnify and hold
LipoMatrix harmless from and against any and all liability, damage, loss, cost,
expense (including reasonable attorney's fees), regulatory penalties and
enforcement actions resulting from any claims made or suits brought against
LipoMatrix, its employees, directors and customers which arise or result solely
from Distributor's marketing, distribution, handling and shipping of the
LipoMatrix Products, or from Distributor's negligence or willful misconduct.
LipoMatrix shall promptly notify Distributor of any such claim or suit and shall
permit Distributor at Distributor's cost and expense, to handle and control such
claim or suit.

        B.     INDEMNITY BY LIPOMATRIX. LipoMatrix shall indemnify and hold
Distributor harmless from and against any and all liability, damage, loss, cost
or expense (including reasonable attorney's fees) resulting from any claims made
or suits brought against Distributor, its employees, directors and customers
which arise or result solely from LipoMatrix's design, handling and shipping of
the LipoMatrix Products, or failure to manufacture the LipoMatrix Products in
accordance with agreed upon specifications, FDA Good Manufacturing Practices or
other applicable standards for medical device manufacturers, or from negligence
or willful misconduct. Distributor shall promptly notify LipoMatrix of any such
claim or suit and shall permit LipoMatrix at LipoMatrix's cost and expense, to
handle and control such claim or suit.

        C.     APPORTIONMENT OF DAMAGES. In the event that any liability, 
damage, loss, cost or expense (including reasonable attorney's fees) as
aforesaid cannot be established (with respect to final judgments of a court of
competent jurisdiction from which no appeal is or can be taken as well as
settlements made prior to, during or following termination of litigation to
which the parties have expressly agreed in writing) to have resulted solely from
the actions or failures to act of LipoMatrix or Distributor or their affiliates,
responsibility for payment of such liability, damage, loss, cost or expense
(including reasonable attorney's fees) will be apportioned between LipoMatrix
and Distributor according to the contribution of either party to the damage; and
if such allocation is not mutually agreed, then it will be determined by
mandatory binding arbitration.

        D.     PRODUCT LIABILITY INSURANCE. LipoMatrix shall use its reasonable
commercial efforts to secure product liability insurance in the amount of five
million dollars ($5,000,000), to the extent this is available on commercially
reasonable terms. LipoMatrix shall have Distributor named as an additional
insured on its product liability insurance policy. If LipoMatrix is unable to
secure or maintain such insurance, Distributor may terminate this Agreement. The
parties agree to review the possibility of increasing the amount of such
insurance if increases in sales so warrant.

IX.     LIMITATION OF LIABILITY

        IN NO EVENT, WHETHER THE CAUSE OF ACTION BE BASED IN CONTRACT OR TORT
(INCLUDING NEGLIGENCE) OR ANY OTHER LEGAL OR EQUITABLE THEORY SHALL EITHER PARTY
BE LIABLE FOR INCIDENTAL, CONSEQUENTIAL, INDIRECT, SPECIAL OR PUNITIVE DAMAGE OF
ANY KIND, OR FOR LOSS OF REVENUE, LOSS OF BUSINESS OR OTHER FINANCIAL LOSS
ARISING OUT OF OR IN CONNECTION WITH THE SALE, USE, PERFORMANCE, FAILURE OR
INTERRUPTIONS OF ITS PRODUCTS. NOTWITHSTANDING ANY OTHER PROVISION OF THIS
AGREEMENT, LIPOMATRIX'S MAXIMUM LIABILITY FOR DAMAGES HEREUNDER SHALL NOT EXCEED
THE PURCHASE PRICE OF THE PRODUCTS PURCHASED DURING THE TERM OF THIS AGREEMENT.
THE FOREGOING LIMITATIONS SHALL NOT AFFECT EITHER PARTY'S DUTY TO INDEMNIFY THE
OTHER PARTY FOR THIRD-PARTY SUITS FOR SUCH DAMAGES, AS SET FORTH IN SECTIONS VII
AND VIII.

        THE DISCLAIMER OF LIABILITY FOR DAMAGES WILL NOT BE AFFECTED IF ANY
REMEDY PROVIDED HEREUNDER SHALL FAIL OF ITS ESSENTIAL PURPOSE. DISTRIBUTOR HAS
ACCEPTED THE DISCLAIMER OF LIABILITY FOR DAMAGES AS PART OF A BARGAIN TO LOWER
THE PRICE OF THE PRODUCTS AND UNDER STANDS THAT THE PRICE OF THE PRODUCTS WOULD
BE HIGHER IF LIPOMATRIX WERE REQUIRED TO BEAR ADDITIONAL LIABILITY FOR DAMAGES.

X.      NO RIGHT TO MANUFACTURE OR COPY

        The Products are offered for sale and are sold by LipoMatrix subject in
every case to the condition that such sale does not convey or license to
Distributor, expressly or by implication, the right to manufacture, duplicate or
otherwise copy or reproduce any of the Products. Distributor shall take
appropriate steps with customers, as mutually agreed, to inform them of, and
both parties shall, as mutually agreed, assist each other in assuring compliance
with, the restrictions contained in this Section.

XI.     INTELLECTUAL PROPERTY RIGHTS

        A.     SOLE PROPERTY OF LIPOMATRIX. Distributor agrees that Intellectual

               Each party agrees that it shall not use in any way for its own
account or the account of any third party, nor disclose to any third party, any
such confidential information which is revealed to it by the other party. The
receiving party shall take every reasonable precaution to protect the
confidentiality of such information, which in no event shall be less than the
efforts exercised by such party with respect to its own confidential business
information. Distributor and LipoMatrix shall advise each other in the event
that either party considers particular information or materials to be
confidential. Distributor shall not publish any technical description of the
Products beyond the description published by LipoMatrix.

               In the event of expiration or earlier termination of this
Agreement, there shall be no use or disclosure by Distributor or LipoMatrix of
any confidential information, and Distributor shall not manufacture, or have

                                   April, 1995

The following is a discussion of the LipoMatrix, Incorporated Risk Management
Program for the company's TRILUCENT(TM) Breast Implant.

The strong linkage and trail of mutual accountability among manufacturer,
distributor, surgeon and consumer as a result of full employment of the measures
described in this Risk Management Program provides benefits for all parties. The
manufacturer is responsible and accountable for its products, and remains
informed of the performance of the product in the marketplace. The distributor
is in the communication loop in providing tools to the surgeon as a condition of
availability of TRILUCENT. The surgeon is kept fully aware of product benefits
and risks, and is provided with educational tools to facilitate communication
with his/her patient. The patient- consumer is responsible, having received
adequate information, for making an enlightened decision based on personal
choice and full understanding of risk vs. benefit - while also taking comfort in
knowing that a degree of protection from the financial consequences of an
adverse event is provided.

While there is no way to eliminate loss exposure, a strong risk management
program (such as detailed here) may reduce loss exposure and enhance physician
and patient satisfaction through better information.

PRODUCT OVERVIEW

The basic building block of a risk management program is a product that is
appropriately designed and tested. The TRILUCENT implant represents an entirely
new technology in the field of breast implants. This product addresses and
provides:

        -      Radiolucency - a neutral triglyceride (lipid) filler designed to
               facilitate detection of breast cancer by mammography.

        -      Biocompatibility - metabolism and excretion of the triglyceride
               filler in case of a leak or rupture with minimal or no local or
               systemic consequences.

        -      Resistance to infection - the triglyceride filler is
               bactericidal/fungicidal for a broad spectrum of organisms.

        -      Composite silicone shell - engineered for strength, abrasion
               resistance, integrity, and biocompatibility.

                                        1
<PAGE>   21
        -      Integrated and innovative delivery system - to reduce handling
               errors by the surgeon.

        -      Transponder microchip ID system - designed to allow non-invasive
               device identification at any time, thus facilitating device
               registry, tracking, adverse events reporting and post- market
               surveillance.

LipoMatrix has compiled nearly eight years of pre-clinical studies regarding the
TRILUCENT technology and product. LipoMatrix-sponsored research continues
in-house and at several major U.S. Universities.

LipoMatrix has now compiled a greater than 100-patient experience with up to 12
month follow-up as part of an ongoing multinational, multicenter European
clinical trial of TRILUCENT. The goal is to complete a formal analysis on
approximately 300 subjects followed for one year (minimum) as part of a clinical
database that will continue to accrue following product launch. LipoMatrix
believes that no other breast implant company has sponsored such a comprehensive
prospective study.

On July 15, 1994, after nearly two years of review of pre-clinical data, the
U.S. FDA gave permission to LipoMatrix to conduct IDE-based clinical trials of
its TRILUCENT product in the USA--the first breast implant in history to be
granted such permission. This trial commenced in December, 1994.

RISK MANAGEMENT STRATEGY

LipoMatrix has developed a risk management program, the elements of which,
together with a brief description, are as follows:

PRODUCT LIABILITY INSURANCE

While the proactive risk management approaches described above are critical to
minimizing the risks for all parties, it is also appropriate to maintain product
liability insurance for those cases where claims do occur. As well as providing
protection for the manufacturer's assets, such insurance provides a level of
assurance to surgeons and patients that there is an additional element of
financial support for the TRILUCENT.

There is no guarantee that product liability insurance will be available on
commercially feasible terms. However, LipoMatrix will try to secure such
insurance to the extent commercially reasonable.

<PAGE>   26
PRODUCT WARRANTY - "PATIENT PROTECTION PLAN"

The "PATIENT PROTECTION PLAN" currently features an Extended Warranty provided
as a matter of course by LipoMatrix through its contracts with its distributors.

EXTENDED WARRANTY

This warranty provides that LipoMatrix will supply a free replacement implant of
the same size in case of implant failure within 5 years following initial
successful implantation. Failure is defined as loss of volume, i.e. deflation,
by implant leak or rupture for whatever reason, except medical intervention,
manipulation, or gross negligence or willful misconduct of the patient or
physician.

The only preconditions for receiving this warranty coverage are (i) execution of
the Patient Advisory and Consent document by the patient and surgeon, (ii) entry
by the patient into the Registry, (iii) submission to LipoMatrix of appropriate
documentation of the clinical condition including an attestation by the surgeon
that the failure was not the result of medical intervention or manipulation, and
(iv) that the explanted implant has been returned to LipoMatrix for failure
analysis.

CAVEAT

Notwithstanding this Risk Management Program, there is no assurance that a
patient or other party will not sue or seek other legal remedies and that the
applicable judicial process will not award excessive damages or remedies.

                        --PATIENT ADVISORY AND CONSENT--

PART I:

IMPORTANT INFORMATION ABOUT BREAST IMPLANTS

As manufacturer of the TRILUCENT(TM) Breast Implant, LipoMatrix, Inc., has
carefully assessed potential risk factors associated with breast implants and
has taken precautions in the manufacture of our product. These factors include

- -       compatibility of implant materials with the body and its systems 

- -       need for radiolucency of the implant for better mammography 

- -       need for long-term identification of the implant after it has been
        inserted.

A most important aspect to understand is that breast implants, like any part of
your body, will age. A breast implant is classified as a medical device, and
like any man-made object, may eventually wear out despite the very best
materials and manufacturing techniques. Should that ever happen, it is important
that no harm come to you. You and your surgeon should discuss the life
expectancy of your implant and what to expect if your implant should need
replacement.

To further assure you of our commitment to your well-being, LipoMatrix provides
a Patient Protection Plan, consisting of a Registry and a Warranty, for
recipients of the TRILUCENT Breast Implant.

                                                                    Page 1 of 14
<PAGE>   29
PART II:

COMMON RISK FACTORS OF BREAST IMPLANTS--AND HOW THE TRILUCENT(TM) BREAST IMPLANT
DIFFERS

BREAST CANCER DETECTION AND INTERFERENCE WITH MAMMOGRAPHY

Mammography (breast X-ray) is the world-wide standard for early breast cancer
detection. But breast implants, as they were developed in the mid-1960's,
interfere with the ability to observe the breast during mammography, because
most breast implants contain fillers which are denser than fat. In 1987, several
female radiologists, concerned about women's needs, sought to find a breast
implant that would allow penetration by mammographic X-rays. The TRILUCENT
implant is the result.

Human fat is the lucent "window" through which the glandular tissue is observed
during x-ray and mammography. A "Z number" determines a substance's potential to
interfere with mammography. Human breast fat has a Z number of about 6.0. An
implant filler with a Z number of about 6.0 is a key to facilitating
mammography.

The TRILUCENT Breast Implant is different from other implants because it is
filled with naturally occurring oils and fats from a soybean source--called
"triglycerides"--the same oils found in human breast fat. Since human fat and
the TRILUCENT Breast Implant triglyceride filler have the same X-ray density
(both means that breast fat and the contents of the TRILUCENT implant both allow
penetration by mammography X-rays. These observations have been confirmed by
numerous studies.

Detection of breast cancer depends on many factors, only one of which is the
implant's radiolucency. There may be difficulty in detecting a small cancer with
any implant. You must discuss this important subject with your surgeon.

LEAKAGE:  WHAT HAPPENS WHEN AN IMPLANT FAILS

         Filler in Contact with Tissue

Breast implants may leak or suffer disruption of the shell integrity from wear,
defect or trauma. Sometimes, the cause is not apparent. However, there are
several reasons why a breast implant may fail. One is a simple wearing out of
the silicone

                                                                    Page 2 of 14
<PAGE>   30
shell from normal wrinkling and friction. Another can be due to an accident,
like a fall, or a severe blow to the chest, as in an automobile accident, which
may cause the implant to rupture. Rarely, damage to an implant may occur during
the handling of it at the time of surgery, or in the treatment of a capsular
contracture (scar around the implant ) by capsulotomy. In any of these
instances, the contents of the implant--the filler material--may leak into the
body.

Whether leakage is potentially harmful to the body has to do with the type of
filler material that the implant contains. The body can not completely rid
itself of some older implant fillers. Those fillers, when they leak, may cause
scars and inflammation and may, in some instances, be mistaken for a breast
tumor. Filler which has leaked from that type breast implant may require
surgical removal.

If the salt-water (saline) filler used in some implants was not sterile or if
bacteria or fungus inadvertently entered the filler solution during the
operating procedure, the bacteria or fungus might grow inside the implant. If
contaminated saline should enter the body, the effects may be dangerous.

The TRILUCENT Breast Implant is filled with natural triglycerides with the same
chemical composition as the triglycerides of normal human fat. And the same
triglycerides used in TRILUCENT (USP soy oil) have been used medically for over
40 years as intravenous nutrition for seriously ill patients and premature
infants. Studies indicate that triglycerides will not support bacterial or
fungal growth, and will simply be absorbed and digested by the body's natural
mechanisms in case of leakage--whatever the cause. In some cases, a mild,
localized inflammation or redness may temporarily occur. Theoretically, a small
collection or "cyst" might remain which your doctor could drain.

SHELL FORMULATION TO RESIST WEAR

Silicone shells are used in all breast implants because this solid form of
silicone is strong, elastic and will stretch with breast movement. The silicone
shell used in the TRILUCENT Breast Implant is specially formulated to retain its
structural strength over time. This shell design, coupled with the triglyceride
filler, drastically reduces the possibility of implant leakage from shell wear
and friction. The specially formulated shell also virtually eliminates silicone
residuals from entering the tissues.

                                                                    Page 3 of 14
<PAGE>   31
THE VIGILANCE(TM) IDENTIFICATION SYSTEM AND THE IMPORTANCE OF IMPLANT
IDENTIFICATION 

Because any implantable device may cause concern or need to be checked at some
point, it is important to be able to identify the implant, its origin and its
history, even years after surgery.

LipoMatrix, Inc., has developed the Vigilance(TM) implant identification system
that allows privacy and confidentiality while enabling future identification of
your TRILUCENT implant should it become necessary. The transponder microchip,
which contains a unique code number for the implant, generates no power or
radiation. It is laminated within the breast implant shell. Data associated with
this unique identification system can only be accessed with your permission. The
transponder will not interfere with routine tests or future medical procedures
that you may have. Should it become necessary to identify your breast implant,
even if your records have been lost or if you have forgotten important details
about the implantation surgery or the device itself, a simple hand-held reading
device will allow your surgeon to access information about your implant. This
feature assures you that LipoMatrix always acknowledges responsibility for the
implants it manufactures. No other breast implant has this feature.

CAPSULAR CONTRACTURE/CALCIFICATION

The most common problem with any type of breast implant is a slowly developing
firmness called "capsular contracture." The body's natural response creates a
layer of scar tissue ("capsule") around the entire surface of any type of
implant. Ideally, the scar capsule will remain thin and pliable. However, if the
scar tissue shrinks and thickens (contracts), it may compress the implant,
making the breast round and firm, sometimes tender and immobile. Capsular
contracture can start anytime after surgery, even several years later, most
commonly on one side only. Often, capsular contracture does not occur at all.

Because some form of scar capsule always occurs with a breast implant, capsular
contracture is considered an inherent risk of a breast implant. No one is sure
of the cause, and some women have no scar problems. However, it is believed that
the surgical method--whether placing the implant under the chest muscle or
above--as well as the composition and surface treatment of the shell, can
combine to modify the body's response. This is why the TRILUCENT Breast Implant
is available with a new textured shell design which may reduce scar formation in
most applications. Always discuss treatment of capsular contracture with your
surgeon.

                                                                    Page 4 of 14
<PAGE>   32
Any surgery or injury to the breast may produce small spots of calcium which may
be seen on mammography. These deposits may not occur until years after surgery
and occasionally a biopsy may be necessary to confirm that the spots are
harmless.

WRINKLING AND RIPPLING

Any fluid-filled implant (including TRILUCENT) may exhibit some wrinkling of the
implant shell. If breast tissue is very thin, these wrinkles can show as visible
ripples, especially when leaning forward without a brassiere. Wrinkling can also
produce little corners on the implants that can sometimes be felt if the breast
tissue is very thin.

The above discussion reviews common risk factors associated with breast
implants. Some specific features of the TRILUCENT(TM) Breast Implant are
discussed. It is not intended to be an exhaustive review, nor does it provide a
complete representation of the breast surgery itself, which may differ from
patient to patient. Other implants may pose additional risks. You should discuss
all of the information in this booklet, in detail, with your surgeon. Also ask
him or her to discuss the risks of other implants as well as the surgical
procedure with you, so you understand all factors concerning your breast implant
and your surgery--before the procedure.

                                                                    Page 5 of 14

PART III

RARE OR UNKNOWN RISK FACTORS ASSOCIATED WITH BREAST IMPLANTS

AUTO-IMMUNE AND CONNECTIVE TISSUE DISEASE

A possible connection has been drawn in the medical literature between certain
types of breast implants and auto-immune diseases (connective tissue disorders
such as scleroderma, rheumatoid arthritis, lupus, etc.). These disorders are
rare and an actual cause-and-effect relationship between breast implants and
these diseases has neither been proved nor disproved. Recent studies strongly
suggest no connection.

TRILUCENT implants contain only the solid silicone-rubber of the shell. In
millions of patients with solid silicone-rubber implants (for example, finger
joints), there has been no reported association of these implants with
auto-immune disease.

Fat Emboli Formation (oil droplets in the blood)

Although there is no evidence that fat emboli can occur as a result of
triglycerides being released into the blood in the event of implant rupture,
there is a theoretical risk that this can occur.

POTENTIAL PROBLEMS OF FAT METABOLISM

In the event of TRILUCENT leakage in a normal, healthy individual, the amount of
fat (oil) released is expected to be digested (metabolized) by the body over a
period of several weeks without ill effect. However, if you have a known
cholesterol problem, or other disease of fat metabolism (for example, pathologic
hyperlipemia, lipoid nephrosis, acute pancreatitis with hyperlipidemia, etc.),
it should be discussed thoroughly with your surgeon before opting for a
triglyceride filled breast implant.

BREAST IMPLANTS AND CANCER

There is presently no scientific evidence that links breast implants with
cancer. Recent mass surveys from several sources show only normal and expected
(or even lower than expected) rates of breast cancer in women with breast
implants. Further studies are in progress.

BIRTH DEFECTS

Animal studies conducted to date show no evidence that birth defects are related
or caused by breast implants. However, to rule out that possibility with humans,
further scientific studies are continuing to determine whether breast implants
can be associated with birth defects.

                                                                    Page 6 of 14
<PAGE>   34
BREAST FEEDING

Breast implantation usually does not interfere with breast feeding since the
implant is inserted under--not in--the breast tissue. Most women report no
difficulties in nursing after implantation, though some individuals experience
difficulty with breast feeding even without implants. If breast feeding is a
concern of yours, please discuss the issue in detail with your doctor before
surgery.

                                                                    Page 7 of 14

PART IV:

SURGICAL RISKS AND COMPLICATIONS ASSOCIATED WITH BREAST IMPLANTATION

BLEEDING AND HEMATOMA

Any operation carries the risk of bleeding or hematoma (collection of congealed
blood in the tissues). Active or sudden bleeding after implant surgery is
unusual, but can be controlled and corrected by your surgeon. Small hematomas
will be absorbed by your body like any bruise, but a large one may have to be
drained to permit proper healing. Sometimes, hematoma may contribute to the scar
(capsule) around the breast implant.

SEROMA

Seroma is a collection of fluid around the implant or in the incision space as a
result of tissue irritation. Seromas seldom cause a long-term problem, but
occasionally require drainage.

INFECTION

Infection--indicated by swelling, tenderness, pain and fever--may occur in the
immediate postoperative period after any type of surgery. Infection is rare
after breast implant surgery and is usually treated by antibiotics; but in
severe cases, drainage and implant removal may be required.

CHANGES IN NIPPLE AND BREAST SENSATION

Any breast surgery, including biopsy or breast implant surgery, can result in
increased or decreased sensation of the breast and/or the nipple. This change
can vary in degree and is usually temporary. Occasionally, changes in sensation
may be permanent.

INJURY TO THE BREAST IMPLANT

Rarely, the implant may be weakened or torn by certain medical or surgical
interventions. For example, a closed or open capsulotomy in the treatment of
capsular contracture could result in such an implant injury.

COSMETIC COMPLICATIONS

While your surgeon takes every possible precaution, before and during surgery,
to ensure a satisfactory result, there are still factors which may interfere
with a satisfactory appearance of the breast after surgery. The most common
reasons for dissatisfaction after breast implantation are: firmness or 
distortion of the breast,

                                                                    Page 8 of 14
<PAGE>   36
implant size, scar location or appearance, implant displacement and asymmetry
(unequal size or shape). Please discuss all these factors with your surgeon
before the operation.

OTHER RISKS

There have been anecdotal reports of rare, isolated or unusual breast implant
problems. Please discuss all potential problems with your doctor before the
surgery.

                                                                    Page 9 of 14

PART V:

THE LIPOMATRIX PATIENT PROTECTION PLAN

LipoMatrix, Inc., is proud of its products--and we stand behind them. When you
receive a TRILUCENT Breast Implant you can be assured that every effort has been
made to produce a reliable, long-lasting implant. However, no implant can be
guaranteed to last a lifetime. For this reason, LipoMatrix, Inc., offers each
recipient of the TRILUCENT Breast Implant, the Patient Protection Plan.

REGISTRY PARTICIPATION--THE KEY

For your protection, and to help ensure that information regarding your implant
will be available to any doctor that you may choose in the future, LipoMatrix,
Inc., maintains a Registry for your TRILUCENT Breast Implant(s). Although
participation is optional, it is strongly recommended that you participate in
our Patient Protection Plan. Registry participation entitles you to warranty
protection. (See below.) Benefits you may elect to receive as a member of the
Registry, in addition to the Warranty, include device related updates, etc.
Information recorded in the Registry about your implant and the surgical
procedure will be used by the Company to send patients and their surgeons device
updates, to meet the Company's warranty obligations, for scientific or medical
research purposes, or in connection with national or foreign regulatory or
judicial proceedings.

As the manufacturer of the TRILUCENT Breast Implant, LipoMatrix feels it is our
responsibility to offer you this service. Your participation, however, relies on
you to discuss all aspects of implant identification and registry with your
surgeon. He or she will provide you with the necessary information needed to
join the Registry. In addition, you and your surgeon need to complete the
information required within the Implant Registry and Warranty Pack which is
sealed inside each TRILUCENT Breast Implant package. This Implant Registry and
Warranty Pack will not be available to you until after the surgery. Make sure
your surgeon provides you with the Implant Registry and Warranty Pack for each
TRILUCENT Breast Implant you receive.

THE TRILUCENT(TM) WARRANTY

The Patient Protection Plan features a substantial Warranty against any implicit
defect in the implant. You automatically qualify for this warranty as long as
you and your surgeon have signed the Patient Advisory and Consent document
included at the end of this booklet and you participate in the Implant Registry
for TRILUCENT.

                                                                   Page 10 of 14
<PAGE>   38
The Warranty means that if any TRILUCENT(TM) Breast Implant should fail--that
is, leak and lose volume, for any reason except medical or surgical manipulation
of the implant (for example, closed or open capsulotomy, or surgical implant
adjustment)--within five (5) years after implantation, LipoMatrix will provide a
TRILUCENT replacement implant of the same volume without cost to you or your
surgeon.

It is understood that deflation or implant rupture can occur even many years
after surgery. Our obligation within the Warranty shall extend to providing a
replacement implant only as specifically provided for under the terms and
conditions of the Warranty.

You are solely responsible for the choice of your surgeon and LipoMatrix does
not assume any liability whatsoever for any damage caused by acts or omissions
of the surgeon. Furthermore, this warranty is in lieu of and excludes all other
warranties not expressly set forth herein, whether express or implied by
operation of law or otherwise, subject to a mandatory warranty which cannot be
excluded under applicable laws.

The only preconditions for receiving this warranty coverage are (i) the signing
of the Patient Advisory and Consent document, (ii) entering the Registry for
each implant you receive, (iii) having your implant returned to LipoMatrix
should it need to be removed, so that it can be analyzed, and (iv) arranging for
the treating surgeon to send records to LipoMatrix confirming that the cause of
the leakage was not due to medical intervention.

The signature portion of this Patient Advisory and Consent document should be
signed by you and your surgeon after reviewing and discussing all points covered
in this booklet. Also, make sure you ask your surgeon to provide you with the
Implant Registry and Warranty Pack enclosed with each TRILUCENT Breast Implant
so that you may enter the Registry for each implant you receive.

                                                                   Page 11 of 14

                                             liquid to gel to solid. Silicone is
                                             used in solid form in many types of
                                             medical implants because the body
                                             tolerates solid silicone so well.

                      TRILUCENT(TM) Breast Implant Registry
                Information For Surgeons Concerning Personal Data
                      (reverse side of "Supply Agreement")

LipoMatrix Incorporated ("the Company") maintains a registry of information
about TRILUCENT breast implant use provided voluntarily by its national
distributors, surgeons and TRILUCENT(TM) Breast Implant recipients which is
automatically processed in Switzerland. By completing the "Surgeon Registry
Card" and mailing it to LipoMatrix, you will allow LipoMatrix to maintain
information about each TRILUCENT Breast Implant after its implantation whether
or not the patient chooses to participate in the Registry. By completing the
"Surgeon Registry Card", you will protect patient identity, but also allow for
your patient to enter the Registry with her full implant history if she should
desire to do so at any time in the future.

By completing and mailing the "Surgeon Registry Card" for each implant you
use--after its implantation--you may obtain periodic reports on your implant use
patterns and will be notified if problems develop with any of your patients'
implants in the distant future, should you wish to have such information. You
may obtain, correct, or supplement the information you submit by writing to:

                                    Registry Controller
                                    LipoMatrix, Incorporated
                                    24, Puits Godet

                                    Switzerland

Information provided to the Company on the "Surgeon Registry Card" will be used
by the Company to provide your patient, her designated representative, or her
designated physician, with the information about her TRILUCENT Breast
Implant(s), and will allow the Company to meet its warranty obligations to the
TRILUCENT Breast Implant recipient--your patient. The only other uses of
Registry information shall be for scientific and health research purposes, or in
connection with foreign or national regulatory or judicial proceedings. At your
request, the Company will provide to you the information relating to your name,
address, and TRILUCENT Breast Implant use. Where required or permitted by
applicable foreign or national law, the Company also will provide this
information to foreign or national regulatory authorities and to parties in
connection with foreign or national regulatory or judicial proceedings.

                             COORDINATION AGREEMENT

         This Coordination Agreement (the "Agreement") is entered into as of
March 24, 1995, between LipoMatrix, Incorporated ("LipoMatrix"), a corporation
organized under the law of the British Virgin Islands with an office located at
Puits Godets 24, CH-2000 Neuchatel, Switzerland and Collagen International
Incorporated ("Collagen International"), a corporation organized under the law
of the State of Delaware, United States of America with an office located at 2,
Avenue Gratta-Paille, CH-1000 Lausanne 30 Grey, Switzerland.

         IN CONSIDERATION OF THE MUTUAL PROMISES HEREIN CONTAINED, THE PARTIES
AGREE AS FOLLOWS:

         1.       DISTRIBUTOR APPOINTMENTS.

                  1.1 LipoMatrix desires to appoint certain Collagen
International subsidiaries ("CI Subsidiaries") as distributors of LipoMatrix's
present and future breast implant products and other products intended for use
in cosmetic or reconstructive breast surgery ("Products"), and those CI
Subsidiaries have expressed interest in distributing Products in the countries
of their respective incorporation (collectively, the "Territory"), pursuant to
separate distribution agreements (each, a "Distributor Agreement") containing
terms and conditions as set forth in the form agreement attached hereto as
Exhibit A.

                  1.2 Those CI Subsidiaries that have expressed an interest in
distributing Products are listed in Exhibit B. Collagen International has no
objection to any CI Subsidiary entering into a separate Distributor Agreement on
terms acceptable to such CI Subsidiary.

                  1.3 If Collagen International subsequently establishes a
majority-owned affiliate in a country not designated as part of the Territory,
LipoMatrix and Collagen International agree to enter into negotiations in good
faith with regard to the possibility of including such country in the Territory,
provided however, that this Section will not require LipoMatrix to cancel or
modify pre-existing distribution agreements with third parties. Notwithstanding
the foregoing, if Collagen International and LipoMatrix have not entered into an
agreement within ninety (90) days of Collagen International notifying LipoMatrix
of the establishment of its affiliate and the desire to enter negotiations for
distribution rights, then LipoMatrix shall be free, in its sole discretion, to
distribute, market and sell the Products in such country on its own or in
conjunction with third parties.

                  1.4 If Collagen International or one of its subsidiaries has
an interest in distributing the Products in a country where it does not have a
subsidiary, but does have a third-party distributor, it may notify LipoMatrix of
its desire to distribute the Products in such country. The parties will
negotiate in good faith to arrive at a mutually acceptable distribution
agreement. In addition, prior to entering into an agreement with a third party
for distribution of Products, LipoMatrix will notify Collagen International of
its intentions and, if Collagen International desires, negotiate in good faith
to arrive at a mutually acceptable distribution agreement. In either of these
cases, if agreement cannot be reached within ninety (90) days of initiation of
discussions, 
<PAGE>   2
LipoMatrix will be free to negotiate distribution rights with other parties.
This section will not apply to Spain, Portugal or Latin America.

                  1.5 The parties recognize that it would facilitate the
administration of certain aspects of the Distributor Agreements if Collagen
International would agree to coordinate and perform certain functions on behalf
of the CI Subsidiaries collectively, and Collagen International has agreed to
serve in the limited capacity set forth herein.

         2.       RESEARCH AND DEVELOPMENT FUND.

                  2.1 The Distributor Agreements provide for the establishment
of a research and development fund (the "Fund") to be created by certain
payments equal to five percent (5%) of each distributor's net sales revenue from
sales of Products beginning in April 1997.

                  2.2 LipoMatrix has agreed to collect and deposit these
payments in a separate interest bearing account, and to provide quarterly
statements of the Fund balance to Collagen International, and to use them on
research, development, clinical and manufacturing programs for breast implant
products and other products intended for use in cosmetic or reconstructive
breast surgery, as mutually agreed with each CI Subsidiary.

                  2.3 LipoMatrix, Collagen International and the CI Subsidiaries
recognize that it would be cumbersome for LipoMatrix to have to reach and
coordinate agreement on the use of the Fund with each CI Subsidiary, and
therefore, with the support of each CI Subsidiary, Collagen International and
LipoMatrix have agreed that Collagen International will perform this
coordination function on the CI Subsidiaries' collective behalf. As a result, a
decision on the use of the Fund for specific projects by Collagen International
will be deemed as binding for each CI Subsidiary.

         3.       RESOLUTION OF DISPUTES.

                  3.1 The parties wish to attempt to resolve any disputes or
disagreements that might arise under any Distributor Agreement that cannot be
resolved by LipoMatrix and the management of the relevant CI Subsidiary without
resort to formal arbitration or litigation wherever possible.

                  3.2 Wherever a dispute has arisen that cannot be resolved, as
described in Section 3.1, the chief executive officers of LipoMatrix and
Collagen International will meet to attempt to resolve it.

                  3.3 In the event the dispute cannot be resolved under Section
3.2, the chief executive officers of LipoMatrix and Collagen International will
refer the dispute to a panel of three arbitrators, one appointed by each party,
and the third by the two appointed arbitrators, convened under the rules of the
International Chamber of Commerce in Geneva, Switzerland.

                  3.4 The decision of the chief executive officers under Section
3.2 or, when necessary, of the arbitrators under Section 3.3, shall be final and
conclusive and binding on LipoMatrix and the relevant CI Subsidiary with respect
to the matter in dispute.

<PAGE>   3
                  3.5 Collagen International represents that each CI Subsidiary
that has signed a Distributor Agreement has agreed to this mechanism for
resolving any disputes that may arise.

         4.       MOST FAVORED DISTRIBUTOR.

                  4.1 LipoMatrix agrees that the prices offered to its
distributors in the European Union ("E.U.") will be not less than the lowest
price ("the Lowest Price") at which Products are sold to subsidiaries of
Collagen International in the E.U. (currently Collagen (UK) Ltd.) as of the date
of this Agreement. In addition, LipoMatrix agrees that the prices at which
Products are sold to its Latin American distributors will be not less than
eighty-five percent (85%) of such Lowest Price.

                  4.2 LipoMatrix agrees that prior to entering a distribution
agreement with a third party for Israel, Poland or Hungary, that it will discuss
pricing for that agreement with Collagen International in an attempt to arrive
at a mutually acceptable arrangement.

                  4.3 LipoMatrix agrees that three (3) years after the date of
this Agreement, the payment terms granted to subsidiaries of Collagen
International will be reviewed to ensure that those subsidiaries are treated
fairly in comparison to other LipoMatrix distributors.

         5.       TARGET LAUNCH DATES.

                  5.1 Assuming the appropriate regulatory clearances are
obtained, the target launch dates for each of the CI Subsidiaries listed in
Exhibit B are as follows:

<TABLE>
<CAPTION>

United Kingdom                               April 1995

Germany                                      September 1995

France                                       October or November 1995

Luxembourg, The Netherlands                  March 31, 1996

Italy                                        first quarter 1996

Australia, Canada                            second quarter 1996

</TABLE>

In the event that any launch is delayed due to regulatory considerations, such
launch will take place as soon as practicable after regulatory considerations
permit, and the remaining target launch dates will be adjusted, if necessary, to
assure that no two (2) launches will be required to occur at an interval of less
than four (4) weeks, and that a launch will not be required to take place in a
month that would not be appropriate due to holiday or seasonal considerations.

the breach within thirty (30) days of written notice thereof.

paid therefore by Distributor, and recover possession of such Products.
LipoMatrix shall not be liable for any costs or expenses incurred without its
prior written authorization.

         Notwithstanding the provisions of the preceding paragraphs, LipoMatrix
shall not be liable to Distributor or its customers for: (a) infringement of
patent claims covering the usage of LipoMatrix Products in a manner not intended
under this Agreement; (b) any trademark infringements involving any marking or
branding applied by LipoMatrix or involving any marking or branding applied at
the request of Distributor, except if such marking or branding is owned by
LipoMatrix; (c) the modification of Products, or any part thereof, unless such
modification was 

                                      -11-
<PAGE>   21
made by LipoMatrix; or (d) the combination, operation or use of the Product with
other products not furnished by LipoMatrix to the extent such claim would not
have arisen had such combination, operation or use not occurred.

         THE FOREGOING PROVISIONS OF THIS SECTION VII STATE THE ENTIRE LIABILITY
AND OBLIGATIONS OF LIPOMATRIX, AND THE EXCLUSIVE REMEDIES OF DISTRIBUTOR AND ITS
CUSTOMERS WITH RESPECT TO ANY ALLEGED INFRINGEMENT OF PATENTS, COPYRIGHTS,
TRADEMARKS, OR OTHER INTELLECTUAL PROPERTY RIGHTS, BY THE PRODUCTS OR ANY PART
THEREOF.

VIII.    PRODUCT LIABILITY 

         A. INDEMNITY BY DISTRIBUTOR. Distributor shall indemnify and hold
LipoMatrix harmless from and against any and all liability, damage, loss, cost,
expense (including reasonable attorney's fees), regulatory penalties and
enforcement actions resulting from any claims made or suits brought against
LipoMatrix, its employees, directors and customers which arise or result solely
from Distributor's marketing, distribution, handling and shipping of the
LipoMatrix Products, or from Distributor's negligence or willful misconduct.
LipoMatrix shall promptly notify Distributor of any such claim or suit and shall
permit Distributor at Distributor's cost and expense, to handle and control such
claim or suit.

         B. INDEMNITY BY LIPOMATRIX. LipoMatrix shall indemnify and hold
Distributor harmless from and against any and all liability, damage, loss, cost
or expense (including reasonable attorney's fees) resulting from any claims made
or suits brought against Distributor, its owners, employees, directors and
customers which arise or result solely from LipoMatrix's design, handling and
shipping of the LipoMatrix Products, or failure to manufacture the LipoMatrix
Products in accordance with agreed upon specifications, FDA Good Manufacturing
Practices or other applicable standards for medical device manufacturers, or
from negligence or willful misconduct. Distributor shall promptly notify
LipoMatrix of any such claim or suit and shall permit LipoMatrix at LipoMatrix's
cost and expense, to handle and control such claim or suit.

         C. APPORTIONMENT OF DAMAGES. In the event that any liability, damage,
loss, cost or expense (including reasonable attorney's fees) as aforesaid cannot
be established (with respect to final judgments of a court of competent
jurisdiction from which no appeal is or can be taken as well as settlements made
prior to, during or following termination of litigation to which the parties
have expressly agreed in writing) to have resulted solely from the actions or
failures to act of LipoMatrix or Distributor or their affiliates, responsibility
for payment of such liability, damage, loss, cost or expense (including
reasonable attorney's fees) will be apportioned between LipoMatrix and
Distributor according to the contribution of either party to the damage; and if
such allocation is not mutually agreed, then it will be determined by mandatory
binding arbitration.

         D. PRODUCT LIABILITY INSURANCE. LipoMatrix shall use its reasonable
commercial efforts to secure product liability insurance in the amount of five
million dollars ($5,000,000), to the extent this is available on commercially
reasonable terms. LipoMatrix shall have Distributor named as an additional
insured on its product liability insurance policy. If LipoMatrix is unable to

                                      -12-
<PAGE>   22
secure or maintain such insurance, Distributor may terminate this Agreement. The
parties agree to review the possibility of increasing the amount of such
insurance if increases in sales so warrant.

IX.      LIMITATION OF LIABILITY

         IN NO EVENT, WHETHER THE CAUSE OF ACTION BE BASED IN CONTRACT OR TORT
(INCLUDING NEGLIGENCE) OR ANY OTHER LEGAL OR EQUITABLE THEORY SHALL EITHER PARTY
BE LIABLE FOR INCIDENTAL, CONSEQUENTIAL, INDIRECT, SPECIAL OR PUNITIVE DAMAGE OF
ANY KIND, OR FOR LOSS OF REVENUE, LOSS OF BUSINESS OR OTHER FINANCIAL LOSS
ARISING OUT OF OR IN CONNECTION WITH THE SALE, USE, PERFORMANCE, FAILURE OR
INTERRUPTIONS OF ITS PRODUCTS. NOTWITHSTANDING ANY OTHER PROVISION OF THIS
AGREEMENT, LIPOMATRIX'S MAXIMUM LIABILITY FOR DAMAGES HEREUNDER SHALL NOT EXCEED
THE PURCHASE PRICE OF THE PRODUCTS PURCHASED DURING THE TERM OF THIS AGREEMENT.
THE FOREGOING LIMITATIONS SHALL NOT AFFECT EITHER PARTY'S DUTY TO INDEMNIFY THE
OTHER PARTY FOR THIRD-PARTY SUITS FOR SUCH DAMAGES, AS SET FORTH IN SECTIONS VII
AND VIII.

         THE DISCLAIMER OF LIABILITY FOR DAMAGES WILL NOT BE AFFECTED IF ANY
REMEDY PROVIDED HEREUNDER SHALL FAIL OF ITS ESSENTIAL PURPOSE. DISTRIBUTOR HAS
ACCEPTED THE DISCLAIMER OF LIABILITY FOR DAMAGES AS PART OF A BARGAIN TO LOWER
THE PRICE OF THE PRODUCTS AND UNDERSTANDS THAT THE PRICE OF THE PRODUCTS WOULD
BE HIGHER IF LIPOMATRIX WERE REQUIRED TO BEAR ADDITIONAL LIABILITY FOR DAMAGES.

X.       NO RIGHT TO MANUFACTURE OR COPY

         The Products are offered for sale and are sold by LipoMatrix subject in
every case to the condition that such sale does not convey or license to
Distributor, expressly or by implication, the right to manufacture, duplicate or
otherwise copy or reproduce any of the Products. Distributor shall take
appropriate steps with customers, as mutually agreed, to inform them of, and
both parties shall, as mutually agreed, assist each other in assuring compliance
with, the restrictions contained in this Section.

                  Each party agrees that it shall not use in any way for its own
account or the account of any third party, nor disclose to any third party, any
such confidential information which is revealed to it by the other party. The
receiving party shall take every reasonable precaution to protect the
confidentiality of such information, which in no event shall be less than the
efforts exercised by such party with respect to its own confidential business
information. Distributor and LipoMatrix shall advise each other in the event
that either party considers particular information or materials to be
confidential. Distributor shall not publish any technical description of the
Products beyond the description published by LipoMatrix.

                  In the event of expiration or earlier termination of this

                                   April, 1995

The following is a discussion of the LipoMatrix, Incorporated Risk Management
Program for the company's TRILUCENT(TM) Breast Implant.

The strong linkage and trail of mutual accountability among manufacturer,
distributor, surgeon and consumer as a result of full employment of the measures
described in this Risk Management Program provides benefits for all parties. The
manufacturer is responsible and accountable for its products, and remains
informed of the performance of the product in the marketplace. The distributor
is in the communication loop in providing tools to the surgeon as a condition of
availability of TRILUCENT. The surgeon is kept fully aware of product benefits
and risks, and is provided with educational tools to facilitate communication
with his/her patient. The patient-consumer is responsible, having received
adequate information, for making an enlightened decision based on personal
choice and full understanding of risk vs. benefit - while also taking comfort in
knowing that a degree of protection from the financial consequences of an
adverse event is provided.

While there is no way to eliminate loss exposure, a strong risk management
program (such as detailed here) may reduce loss exposure and enhance physician
and patient satisfaction through better information.

PRODUCT OVERVIEW

The basic building block of a risk management program is a product that is
appropriately designed and tested. The TRILUCENT implant represents an entirely
new technology in the field of breast implants. This product addresses and
provides:

     -    Radiolucency - a neutral triglyceride (lipid) filler designed to
          facilitate detection of breast cancer by mammography.

     -    Biocompatibility - metabolism and excretion of the triglyceride filler
          in case of a leak or rupture with minimal or no local or systemic
          consequences.

     -    Resistance to infection - the triglyceride filler is
          bactericidal/fungicidal for a broad spectrum of organisms.

     -    Composite silicone shell - engineered for strength, abrasion
          resistance, integrity, and biocompatibility.
 
                                        1
<PAGE>   28
     -    Integrated and innovative delivery system - to reduce handling errors
          by the surgeon.

     -    Transponder microchip ID system - designed to allow non-invasive
          device identification at any time, thus facilitating device registry,
          tracking, adverse events reporting and post-market surveillance.

LipoMatrix has compiled nearly eight years of pre-clinical studies regarding the
TRILUCENT technology and product. LipoMatrix-sponsored research continues
in-house and at several major U.S. Universities.

LipoMatrix has now compiled a GREATER THAN 100-patient experience with up to 12
month follow-up as part of an ongoing multinational, multicenter European
clinical trial of TRILUCENT. The goal is to complete a formal analysis on
approximately 300 subjects followed for one year (minimum) as part of a clinical
database that will continue to accrue following product launch. LipoMatrix
believes that no other breast implant company has sponsored such a comprehensive
prospective study.

On July 15, 1994, after nearly two years of review of pre-clinical data, the
U.S. FDA gave permission to LipoMatrix to conduct IDE-based clinical trials of
its TRILUCENT product in the USA - the first breast implant in history to be
granted such permission. This trial commenced in December, 1994.

RISK MANAGEMENT STRATEGY

LipoMatrix has developed a risk management program, the elements of which,
together with a brief description, are as follows:

                                       5
<PAGE>   32
PRODUCT LIABILITY INSURANCE

While the proactive risk management approaches described above are critical to
minimizing the risks for all parties, it is also appropriate to maintain product
liability insurance for those cases where claims do occur. As well as providing
protection for the manufacturer's assets, such insurance provides a level of
assurance to surgeons and patients that there is an additional element of
financial support for the TRILUCENT.

There is no guarantee that product liability insurance will be available on
commercially feasible terms. However, LipoMatrix will try to secure such
insurance to the extent commercially reasonable.

                                       6
<PAGE>   33
PRODUCT WARRANTY - "PATIENT PROTECTION PLAN"

The "PATIENT PROTECTION PLAN" currently features an Extended Warranty provided
as a matter of course by LipoMatrix through its contracts with its distributors.

EXTENDED WARRANTY
This warranty provides that LipoMatrix will supply a free replacement implant of
the same size in case of implant failure within 5 years following initial
successful implantation. Failure is defined as loss of volume, i.e. deflation,
by implant leak or rupture for whatever reason, except medical intervention,
manipulation, or gross negligence or willful misconduct of the patient or
physician.

The only preconditions for receiving this warranty coverage are (i) execution of
the Patient Advisory and Consent document by the patient and surgeon, (ii) entry
by the patient into the Registry, (iii) submission to LipoMatrix of appropriate
documentation of the clinical condition including an attestation by the surgeon
that the failure was not the result of medical intervention or manipulation, and
(iv) that the explanted implant has been returned to LipoMatrix for failure
analysis.

CAVEAT

Notwithstanding this Risk Management Program, there is no assurance that a
patient or other party will not sue or seek other legal remedies and that the
applicable judicial process will not award excessive damages or remedies.

                        THE TRILUCENT(TM) BREAST IMPLANT
                        --PATIENT ADVISORY AND CONSENT--

PART I:
IMPORTANT INFORMATION ABOUT BREAST IMPLANTS

As manufacturer of the TRILUCENT(TM) Breast Implant, LipoMatrix, Inc., has
carefully assessed potential risk factors associated with breast implants and
has taken precautions in the manufacture of our product. These factors include

     - compatibility of implant materials with the body and its systems 
     - need for radiolucency of the implant for better mammography 
     - need for long-term identification of the implant after it has been 
       inserted.

A most important aspect to understand is that breast implants, like any part of
your body, will age. A breast implant is classified as a medical device, and
like any man-made object, may eventually wear out despite the very best
materials and manufacturing techniques. Should that ever happen, it is important
that no harm come to you. You and your surgeon should discuss the life
expectancy of your implant and what to expect if your implant should need
replacement.

To further assure you of our commitment to your well-being, LipoMatrix provides
a Patient Protection Plan, consisting of a Registry and a Warranty, for
recipients of the TRILUCENT Breast Implant.
<PAGE>   36
PART II: 
COMMON RISK FACTORS OF BREAST IMPLANTS--AND HOW THE TRILUCENT(TM) BREAST IMPLANT
DIFFERS

BREAST CANCER DETECTION AND INTERFERENCE WITH MAMMOGRAPHY

Mammography (breast X-ray) is the world-wide standard for early breast cancer
detection. But breast implants, as they were developed in the mid-1960's,
interfere with the ability to observe the breast during mammography, because
most breast implants contain fillers which are denser than fat. In 1987, several
female radiologists, concerned about women's needs, sought to find a breast
implant that would allow penetration by mammographic X-rays. The TRILUCENT
implant is the result.

Human fat is the lucent "window" through which the glandular tissue is observed
during x-ray and mammography. A "Z number" determines a substance's potential to
interfere with mammography. Human breast fat has a Z number of about 6.0. An
implant filler with a Z number of about 6.0 is a key to facilitating
mammography.

The TRILUCENT Breast Implant is different from other implants because it is
filled with naturally occurring oils and fats from a soybean source--called
"triglycerides"--the same oils found in human breast fat. Since human fat and
the TRILUCENT Breast Implant triglyceride filler have the same X-ray density
(both have a "Z number" of about 6), they also have the equivalent
"radiolucency." This means that breast fat and the contents of the TRILUCENT
implant both allow penetration by mammography X-rays. These observations have
been confirmed by numerous studies.

Detection of breast cancer depends on many factors, only one of which is the
implant's radiolucency. There may be difficulty in detecting a small cancer with
any implant. You must discuss this important subject with your surgeon.

LEAKAGE:  WHAT HAPPENS WHEN AN IMPLANT FAILS

         FILLER IN CONTACT WITH TISSUE
Breast implants may leak or suffer disruption of the shell integrity from wear,
defect or trauma. Sometimes, the cause is not apparent. However, there are
several reasons why a breast implant may fail. One is a simple wearing out of
the silicone
<PAGE>   37
shell from normal wrinkling and friction. Another can be due to an accident,
like a fall, or a severe blow to the chest, as in an automobile accident, which
may cause the implant to rupture. Rarely, damage to an implant may occur during
the handling of it at the time of surgery, or in the treatment of a capsular
contracture (scar around the implant ) by capsulotomy. In any of these
instances, the contents of the implant--the filler material--may leak into the
body.

Whether leakage is potentially harmful to the body has to do with the type of
filler material that the implant contains. The body can not completely rid
itself of some older implant fillers. Those fillers, when they leak, may cause
scars and inflammation and may, in some instances, be mistaken for a breast
tumor. Filler which has leaked from that type breast implant may require
surgical removal.

If the salt-water (saline) filler used in some implants was not sterile or if
bacteria or fungus inadvertently entered the filler solution during the
operating procedure, the bacteria or fungus might grow inside the implant. If
contaminated saline should enter the body, the effects may be dangerous.

The TRILUCENT Breast Implant is filled with natural triglycerides with the same
chemical composition as the triglycerides of normal human fat. And the same
triglycerides used in TRILUCENT (USP soy oil) have been used medically for over
40 years as intravenous nutrition for seriously ill patients and premature
infants. Studies indicate that triglycerides will not support bacterial or
fungal growth, and will simply be absorbed and digested by the body's natural
mechanisms in case of leakage--whatever the cause. In some cases, a mild,
localized inflammation or redness may temporarily occur. Theoretically, a small
collection or "cyst" might remain which your doctor could drain.

SHELL FORMULATION TO RESIST WEAR
Silicone shells are used in all breast implants because this solid form of
silicone is strong, elastic and will stretch with breast movement. The silicone
shell used in the TRILUCENT Breast Implant is specially formulated to retain its
structural strength over time. This shell design, coupled with the triglyceride
filler, drastically reduces the possibility of implant leakage from shell wear
and friction. The specially formulated shell also virtually eliminates silicone
residuals from entering the tissues.
<PAGE>   38
THE VIGILANCE(TM) IDENTIFICATION SYSTEM AND THE IMPORTANCE OF IMPLANT
IDENTIFICATION
Because any implantable device may cause concern or need to be checked at some
point, it is important to be able to identify the implant, its origin and its
history, even years after surgery.

LipoMatrix, Inc., has developed the Vigilance(TM) implant identification system
that allows privacy and confidentiality while enabling future identification of
your TRILUCENT implant should it become necessary. The transponder microchip,
which contains a unique code number for the implant, generates no power or
radiation. It is laminated within the breast implant shell. Data associated with
this unique identification system can only be accessed with your permission. The
transponder will not interfere with routine tests or future medical procedures
that you may have. Should it become necessary to identify your breast implant,
even if your records have been lost or if you have forgotten important details
about the implantation surgery or the device itself, a simple hand-held reading
device will allow your surgeon to access information about your implant. This
feature assures you that LipoMatrix always acknowledges responsibility for the
implants it manufactures. No other breast implant has this feature.

CAPSULAR CONTRACTURE/CALCIFICATION
The most common problem with any type of breast implant is a slowly developing
firmness called "capsular contracture." The body's natural response creates a
layer of scar tissue ("capsule") around the entire surface of any type of
implant. Ideally, the scar capsule will remain thin and pliable. However, if the
scar tissue shrinks and thickens (contracts), it may compress the implant,
making the breast round and firm, sometimes tender and immobile. Capsular
contracture can start anytime after surgery, even several years later, most
commonly on one side only. Often, capsular contracture does not occur at all.

Because some form of scar capsule always occurs with a breast implant, capsular
contracture is considered an inherent risk of a breast implant. No one is sure
of the cause, and some women have no scar problems. However, it is believed that
the surgical method--whether placing the implant under the chest muscle or
above--as well as the composition and surface treatment of the shell, can
combine to modify the body's response. This is why the TRILUCENT Breast Implant
is available with a new textured shell design which may reduce scar formation in
most applications. Always discuss treatment of capsular contracture with your
surgeon.
<PAGE>   39
Any surgery or injury to the breast may produce small spots of calcium which may
be seen on mammography. These deposits may not occur until years after surgery
and occasionally a biopsy may be necessary to confirm that the spots are
harmless.

WRINKLING AND RIPPLING
Any fluid-filled implant (including TRILUCENT) may exhibit some wrinkling of the
implant shell. If breast tissue is very thin, these wrinkles can show as visible
ripples, especially when leaning forward without a brassiere. Wrinkling can also
produce little corners on the implants that can sometimes be felt if the breast
tissue is very thin.

The above discussion reviews common risk factors associated with breast
implants. Some specific features of the TRILUCENT(TM) Breast Implant are
discussed. It is not intended to be an exhaustive review, nor does it provide a
complete representation of the breast surgery itself, which may differ from
patient to patient. Other implants may pose additional risks. You should discuss
all of the information in this booklet, in detail, with your surgeon. Also ask
him or her to discuss the risks of other implants as well as the surgical
procedure with you, so you understand all factors concerning your breast implant
and your surgery--before the procedure.

PART III
RARE OR UNKNOWN RISK FACTORS ASSOCIATED WITH BREAST IMPLANTS

AUTO-IMMUNE AND CONNECTIVE TISSUE DISEASE
A possible connection has been drawn in the medical literature between certain
types of breast implants and auto-immune diseases (connective tissue disorders
such as scleroderma, rheumatoid arthritis, lupus, etc.). These disorders are
rare and an actual cause-and-effect relationship between breast implants and
these diseases has neither been proved nor disproved. Recent studies strongly
suggest no connection.

TRILUCENT implants contain only the solid silicone-rubber of the shell. In
millions of patients with solid silicone-rubber implants (for example, finger
joints), there has been no reported association of these implants with
auto-immune disease.

FAT EMBOLI FORMATION (OIL DROPLETS IN THE BLOOD)
Although there is no evidence that fat emboli can occur as a result of
triglycerides being released into the blood in the event of implant rupture,
there is a theoretical risk that this can occur.

POTENTIAL PROBLEMS OF FAT METABOLISM
In the event of TRILUCENT leakage in a normal, healthy individual, the amount of
fat (oil) released is expected to be digested (metabolized) by the body over a
period of several weeks without ill effect. However, if you have a known
cholesterol problem, or other disease of fat metabolism (for example, pathologic
hyperlipemia, lipoid nephrosis, acute pancreatitis with hyperlipidemia, etc.),
it should be discussed thoroughly with your surgeon before opting for a
triglyceride filled breast implant.

BREAST IMPLANTS AND CANCER
There is presently no scientific evidence that links breast implants with
cancer. Recent mass surveys from several sources show only normal and expected
(or even lower than expected) rates of breast cancer in women with breast
implants. Further studies are in progress.

BIRTH DEFECTS
Animal studies conducted to date show no evidence that birth defects are related
or caused by breast implants. However, to rule out that possibility with humans,
further scientific studies are continuing to determine whether breast implants
can be associated with birth defects.
<PAGE>   41
BREAST FEEDING
Breast implantation usually does not interfere with breast feeding since the
implant is inserted under--not in--the breast tissue. Most women report no
difficulties in nursing after implantation, though some individuals experience
difficulty with breast feeding even without implants. If breast feeding is a
concern of yours, please discuss the issue in detail with your doctor before
surgery.
<PAGE>   42
PART IV:
SURGICAL RISKS AND COMPLICATIONS ASSOCIATED WITH BREAST IMPLANTATION

BLEEDING AND HEMATOMA
Any operation carries the risk of bleeding or hematoma (collection of congealed
blood in the tissues). Active or sudden bleeding after implant surgery is
unusual, but can be controlled and corrected by your surgeon. Small hematomas
will be absorbed by your body like any bruise, but a large one may have to be
drained to permit proper healing. Sometimes, hematoma may contribute to the scar
(capsule) around the breast implant.

SEROMA
Seroma is a collection of fluid around the implant or in the incision space as a
result of tissue irritation. Seromas seldom cause a long-term problem, but
occasionally require drainage.

INFECTION
Infection--indicated by swelling, tenderness, pain and fever--may occur in the
immediate post-operative period after any type of surgery. Infection is rare
after breast implant surgery and is usually treated by antibiotics; but in
severe cases, drainage and implant removal may be required.

CHANGES IN NIPPLE AND BREAST SENSATION
Any breast surgery, including biopsy or breast implant surgery, can result in
increased or decreased sensation of the breast and/or the nipple. This change
can vary in degree and is usually temporary. Occasionally, changes in sensation
may be permanent.

INJURY TO THE BREAST IMPLANT
Rarely, the implant may be weakened or torn by certain medical or surgical
interventions. For example, a closed or open capsulotomy in the treatment of
capsular contracture could result in such an implant injury.

COSMETIC COMPLICATIONS
While your surgeon takes every possible precaution, before and during surgery,
to ensure a satisfactory result, there are still factors which may interfere
with a satisfactory appearance of the breast after surgery. The most common
reasons for dissatisfaction after breast implantation are: firmness or
distortion of the breast,
<PAGE>   43
implant size, scar location or appearance, implant displacement and asymmetry
(unequal size or shape). Please discuss all these factors with your surgeon
before the operation.

OTHER RISKS
There have been anecdotal reports of rare, isolated or unusual breast implant
problems. Please discuss all potential problems with your doctor before the
surgery.
<PAGE>   44
PART V:
THE LIPOMATRIX PATIENT PROTECTION PLAN

LipoMatrix, Inc., is proud of its products--and we stand behind them. When you
receive a TRILUCENT Breast Implant you can be assured that every effort has been
made to produce a reliable, long-lasting implant. However, no implant can be
guaranteed to last a lifetime. For this reason, LipoMatrix, Inc., offers each
recipient of the TRILUCENT Breast Implant, the Patient Protection Plan.

REGISTRY PARTICIPATION--THE KEY
For your protection, and to help ensure that information regarding your implant
will be available to any doctor that you may choose in the future, LipoMatrix,
Inc., maintains a Registry for your TRILUCENT Breast Implant(s). Although
participation is optional, it is strongly recommended that you participate in
our Patient Protection Plan. Registry participation entitles you to warranty
protection. (See below.) Benefits you may elect to receive as a member of the
Registry, in addition to the Warranty, include device related updates, etc.
Information recorded in the Registry about your implant and the surgical
procedure will be used by the Company to send patients and their surgeons device
updates, to meet the Company's warranty obligations, for scientific or medical
research purposes, or in connection with national or foreign regulatory or
judicial proceedings.

As the manufacturer of the TRILUCENT Breast Implant, LipoMatrix feels it is our
responsibility to offer you this service. Your participation, however, relies on
you to discuss all aspects of implant identification and registry with your
surgeon. He or she will provide you with the necessary information needed to
join the Registry. In addition, you and your surgeon need to complete the
information required within the Implant Registry and Warranty Pack which is
sealed inside each TRILUCENT Breast Implant package. This Implant Registry and
Warranty Pack will not be available to you until after the surgery. Make sure
your surgeon provides you with the Implant Registry and Warranty Pack for each
TRILUCENT Breast Implant you receive.

THE TRILUCENT(TM) WARRANTY
The Patient Protection Plan features a substantial Warranty against any implicit
defect in the implant. You automatically qualify for this warranty as long as
you and your surgeon have signed the Patient Advisory and Consent document
included at the end of this booklet and you participate in the Implant Registry
for TRILUCENT.
<PAGE>   45
The Warranty means that if any TRILUCENT(TM) Breast Implant should fail--that
is, leak and lose volume, for any reason except medical or surgical manipulation
of the implant (for example, closed or open capsulotomy, or surgical implant
adjustment)--within five (5) years after implantation, LipoMatrix will provide a
TRILUCENT replacement implant of the same volume without cost to you or your
surgeon.

It is understood that deflation or implant rupture can occur even many years
after surgery. Our obligation within the Warranty shall extend to providing a
replacement implant only as specifically provided for under the terms and
conditions of the Warranty.

You are solely responsible for the choice of your surgeon and LipoMatrix does
not assume any liability whatsoever for any damage caused by acts or omissions
of the surgeon. Furthermore, this warranty is in lieu of and excludes all other
warranties not expressly set forth herein, whether express or implied by
operation of law or otherwise, subject to a mandatory warranty which cannot be
excluded under applicable laws.

The only preconditions for receiving this warranty coverage are (i) the signing
of the Patient Advisory and Consent document, (ii) entering the Registry for
each implant you receive, (iii) having your implant returned to LipoMatrix
should it need to be removed, so that it can be analyzed, and (iv) arranging for
the treating surgeon to send records to LipoMatrix confirming that the cause of
the leakage was not due to medical intervention.

The signature portion of this Patient Advisory and Consent document should be
signed by you and your surgeon after reviewing and discussing all points covered
in this booklet. Also, make sure you ask your surgeon to provide you with the
Implant Registry and Warranty Pack enclosed with each TRILUCENT Breast Implant
so that you may enter the Registry for each implant you receive.

- -------------------------------------------------------------------------------------------------
<S>                        <C>
capsule                    a scar that always forms around any implantable  device placed in the
                           body--including breast implants.
- -------------------------------------------------------------------------------------------------

capsular contracture       tightening   and   thickening  of  the  normal   capsule   around  an
                           implant--sometimes  causing a feeling of firmness or discomfort.  (See
                           "texture.")
- -------------------------------------------------------------------------------------------------

capsulotomy                procedure for relieving the scar contracture around
                           an implant. A closed capsulotomy is an external force
                           applied by the surgeon to manually "break" the
                           internal scar. An open capsulotomy is a surgical
                           means of relieving scar contracture.
- -------------------------------------------------------------------------------------------------

filler                     the  material  contained  within  the  shell  of  a  breast  implant,
                           commonly consisting of silicone-gel, saline or triglyceride.
- -------------------------------------------------------------------------------------------------

mammography                diagnosis of breast lumps by X-ray.
- -------------------------------------------------------------------------------------------------

radiolucent                material  that will  allow  X-ray to  penetrate  through  in order to
                           allow   breast   gland   tissue  to  be   visible.   Breast  fat  and
                           triglycerides are both radiolucent.
- -------------------------------------------------------------------------------------------------

saline implant             a type of breast implant containing salt-water (saline) as a filler.
- -------------------------------------------------------------------------------------------------

shell                      the outer  envelope of a breast  implant.  Implant  shells are always
                           made of solid silicone elastomer (rubber).
- -------------------------------------------------------------------------------------------------

silicone                   a  man-made  substance  that can be  engineering  in many  forms--from
                           liquid  to gel to  solid.  Silicone  is  used in  solid  form in many
                           types of medical  implants  because the body tolerates solid silicone
                           so well.
- -------------------------------------------------------------------------------------------------

silicone-gel implant       a type of breast  implant  containing a semi-fluid type of silicon-a
                           gel.
- -------------------------------------------------------------------------------------------------

texture                    surface  treatment of an implant  shell to roughen it,  attempting to
                           reduce the tendency for the scar capsule to contract.
- -------------------------------------------------------------------------------------------------

transponder microchip      a miniature  marker that can be sealed  within the implant  shell and
                           contains a "serial number" of the implant--for  future  identification
                           if necessary.

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

triglyceride               natural oil (fat).
- -------------------------------------------------------------------------------------------------

Trilipid-Z6(TM)            super refined, medical-grade oil from soybean; found in the
                           TRILUCENT(TM) Breast Implant.
- -------------------------------------------------------------------------------------------------

TRILUCENT(TM) implant      new type of breast implant filled with natural Iglycerides and
                           having the property of being radioTRILUCENT.
- -------------------------------------------------------------------------------------------------

Vigilance(TM) ID system    means of implant identification using transponder microchip and a
                           computerized databank of an implant's history.
- -------------------------------------------------------------------------------------------------

Z-number                   an indicator of radiolucency.  Both breast fat and Trilipid-Z6(TM) 
                           have a Z-number of about 6.  Both are radiolucent.

                      (REVERSE SIDE OF "SUPPLY AGREEMENT")

LipoMatrix Incorporated ("the Company") maintains a registry of information
about TRILUCENT breast implant use provided voluntarily by its national
distributors, surgeons and TRILUCENT(TM) Breast Implant recipients which is
automatically processed in Switzerland. By completing the "Surgeon Registry
Card" and mailing it to LipoMatrix, you will allow LipoMatrix to maintain
information about each TRILUCENT Breast Implant after its implantation whether
or not the patient chooses to participate in the Registry. By completing the
"Surgeon Registry Card", you will protect patient identity, but also allow for
your patient to enter the Registry with her full implant history if she should
desire to do so at any time in the future.

By completing and mailing the "Surgeon Registry Card" for each implant you
use--after its implantation--you may obtain periodic reports on your implant use
patterns and will be notified if problems develop with any of your patients'
implants in the distant future, should you wish to have such information. You
may obtain, correct, or supplement the information you submit by writing to:
