A.G. EDWARDS & SONS, INC.
As Representatives of the several
 Underwriters named in Schedule 1,
C/O LEHMAN BROTHERS INC.
Three World Financial Center
New York, New York 10285


Dear Sirs:

     Selfcare, Inc., a Delaware corporation (the "Company"), proposes to issue
and sell to the several underwriters named in Schedule 1 hereto (the
"Underwriters") 2,000,000 shares (the "Firm Shares") of the Company's Common
Stock, $.001 par value per share (the "Common Stock"). In addition, the Company
proposes to grant to the Underwriters an option to purchase up to an additional
300,000 shares of Common Stock on the terms and for the purposes set forth in
Section 2 (the "Option Shares"). The Firm Shares and the Option Shares, if
purchased, are hereinafter collectively called the "Shares." This is to confirm
the agreement concerning the purchase of the Shares from the Company by the
Underwriters.

     1. Representations, Warranties and Agreements of the Company. The Company
represents, warrants and agrees that:

               (a) A registration statement on Form SB-2 (File No. 333-        )
with respect to the Shares has (i) been prepared by the Company in conformity
with the requirements of the United States Securities Act of 1933, as amended
(the "Securities Act"), and the rules and regulations (the "Rules and
Regulations") of the United States Securities and Exchange Commission (the
"Commission") thereunder, (ii) been filed with the Commission under the
Securities Act and (iii) become effective under the Securities Act. If any
post-effective amendment to such registration statement has been filed with the
Commission prior to the execution and delivery of this 


<PAGE>   2

Agreement, the most recent such amendment has been declared effective by the
Commission. Copies of such registration statement and all amendments thereto,
including post-effective amendments, if any, have been delivered by the Company
to you as the representatives (the "Representatives") of the Underwriters. As
used in this Agreement, "Effective Time" means the date and the time as of which
such registration statement, or the most recent post-effective amendment
thereto, if any, was declared effective by the Commission; "Effective Date"
means the date of the Effective Time; "Preliminary Prospectus" means each
prospectus included in such registration statement or amendments thereof, before
it became effective under the Securities Act and any prospectus filed with the
Commission by the Company with the consent of the Representatives pursuant to
Rule 424(a) of the Rules and Regulations; "Registration Statement" means such
registration statement, as amended at the Effective Time, including all
information contained in the final prospectus filed with the Commission pursuant
to Rule 424(b) of the Rules and Regulations in accordance with Section 5 hereof
and deemed to be a part of the registration statement as of the Effective Time
pursuant to paragraph (b) of Rule 430A of the Rules and Regulations; if the
Company has filed or files a registration statement under Rule 462(b) of the
Rules and Regulations ("Rule 462(b)") to register additional shares (a "Rule
462(b) Registration Statement"), then the term "Registration Statement" shall be
deemed to include such registration statement; and "Prospectus" means such final
prospectus, as first filed with the Commission pursuant to paragraph (1) or (4)
of Rule 424(b) of the Rules and Regulations. The Commission has not issued any
order preventing or suspending the use of any Preliminary Prospectus or
Prospectus or the effectiveness of the Registration Statement, and no proceeding
for any such purpose has been initiated or, to the best of the Company's
knowledge, threatened by the Commission.

               (b) The Registration Statement conforms, and the Prospectus and
any further amendments or supplements to the Registration Statement or the
Prospectus will, when they become effective or are filed with the Commission, as
the case may be, conform in all material respects to the requirements of the
Securities Act and the Rules and Regulations and do not and will not, as of the
applicable effective date (as to the Registration Statement and any amendment
thereto) contain an untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading and as of the applicable filing date (as to a prospectus
and any amendment or supplement thereto) include an untrue statement of a
material fact or omit to state a material fact necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading; provided that the Company makes no representation or warranty as
to information contained in or omitted from the Registration Statement or the
Prospectus in reliance upon and in conformity with written information furnished
to the Company through the Representatives by or on behalf of any Underwriter
specifically for inclusion therein. There is no contract or document required to
be described in the Registration Statement or the Prospectus or to be filed as
an exhibit to the Registration Statement which is not described or filed as
required.

               (c) The Company has no subsidiaries (as defined in Section 15
hereof) other than Selfcare Europe, Ltd., Selfcare Benelux, Selfcare Europe,
GmbH, Cambridge Diagnostics Ireland Limited, Cambridge Affiliate Corporation,
Selfhelp Israel, Ltd., Selfcare International GmbH, Inverness Medical Limited,

                                      2

as foreign corporations in each jurisdiction in which their respective ownership
or leasing of property or the conduct of their respective businesses requires
such qualification, except where the failure to be so qualified would not have a
material adverse effect on the consolidated financial position, stockholders'
equity, results of operations, business or prospects of the Company and its
subsidiaries, considered as a single enterprise (a "Material Adverse Effect"),
and have all power and authority necessary to own or hold their respective
properties and to conduct the businesses in which they are engaged; none of the
subsidiaries (other than Cambridge Diagnostics Ireland Limited) is a
"significant subsidiary", as such term is defined in Rule 405 of the Rules and
Regulations.

               (d) The Company has an authorized capitalization as set forth in
the Prospectus, and all of the outstanding shares of capital stock of the
Company have been duly authorized and validly issued, are fully paid and
non-assessable and conform to the description thereof contained in the
Prospectus; and all of the outstanding shares of capital stock of each
subsidiary have been duly and validly authorized and issued and are fully paid
and non-assessable and, except as described in the Prospectus, are owned
directly by the Company, free and clear of all liens, encumbrances, equities or
claims. There are no preemptive rights or other rights to subscribe for or to
purchase, or, upon consummation of the offering to which this Agreement relates,
any restriction upon the voting or transfer of, any shares of capital stock
pursuant to the Company's Articles of Incorporation, By-laws or other governing
documents or any agreement or other instrument to which the Company is a party
or by which it may be bound, except pursuant to the Company's stock option and
employee stock purchase plans described in the Prospectus and except with
respect to the voting of any shares of capital stock pursuant to that certain
voting agreement among Ron Zwanziger and certain stockholders of the Company
dated May 13, 1996 (the "Voting Agreement").

               (e) The Shares to be issued and sold by the Company to the
Underwriters hereunder have been duly and validly authorized and, when issued
and delivered against payment therefor as provided herein, will be duly and
validly issued, fully paid and non-assessable and not be subject to any
preemptive rights; and the Shares will conform to the description thereof
contained in the Prospectus.

               (f) The Company has full right, corporate power and authority to
enter into this Agreement and to perform and discharge its obligations
hereunder, and this Agreement has been duly authorized, executed and delivered
by the Company and constitutes the valid and legally binding agreement of the
Company, except as rights to indemnification may be limited by federal or state
securities laws and except for the effect of bankruptcy, insolvency,
reorganization, moratorium and other similar laws relating to or affecting the
rights of creditors generally.

               (g) The execution, delivery and performance of this Agreement by
the Company and the consummation of the transactions contemplated hereby will
not conflict with or result in a breach or violation of any of the terms or
provisions of, or constitute a default under, any indenture, mortgage, deed of

in the securities being registered pursuant to the Registration Statement, nor
is it required to file any registration statement for the registration of any

jointly, agrees to purchase the number of the Firm Shares appearing opposite
that Underwriter's name in Schedule 1 hereto. The respective purchase

purchase 

                                       7


<PAGE>   8

up to 300,000 Option Shares. Such option is granted solely for the purpose of
covering over-allotments in the sale of Firm Shares and is exercisable as
provided in Section 4 hereof. Option Shares shall be purchased severally for the
account of the Underwriters in proportion to the number of Firm Shares set forth
opposite the name of such Underwriters in Schedule 1 hereto. The respective
purchase obligations of each Underwriter with respect to the Option Shares shall
be adjusted by the Representatives so that no Underwriter shall be obligated to
purchase Option Shares other than in 100 share quantities. The price of both the
Firm Shares and any Option Shares shall be $   per share.

     The Company shall not be obligated to deliver any of the Shares to be
delivered on the First Delivery Date or the Second Delivery Date (as hereinafter
defined), as the case may be, except upon payment for all of the Shares to be
purchased on such Delivery Date as provided herein.

     3.   Offering of Shares by the Underwriters.

     Upon authorization by the Representatives of the release of the Firm
Shares, the several Underwriters propose to offer the Firm Shares for sale upon
the terms and conditions set forth in the Prospectus.

     [It is understood that [__________] shares of the Firm Stock will initially
be reserved by the several Underwriters for offer and sale upon the terms and
conditions set forth in the Prospectus and in accordance with the rules and
regulations of the National Association of Securities Dealers, Inc. to employees
and persons having business relationships with the Company and its subsidiaries
who have heretofore delivered to the Representatives offers to purchase shares
of Firm Stock in form satisfactory to the Representatives, and that any
allocation of such Firm Stock among such persons will be made in accordance with
timely directions received by the Representatives from the Company; provided,
that under no circumstances will the Representatives or any Underwriter be
liable to the Company or to any such person for any action taken or omitted in
good faith in connection with such offering to employees and persons having
business relationships with the Company and its subsidiaries. It is further
understood that any shares of such Firm Stock which are not purchased by such
persons will be offered by the Underwriters to the public upon the terms and
conditions set forth in the Prospectus.]

Delivery Date, the Company shall deliver or cause to be delivered certificates
representing the Firm Shares to the Representatives for the account of each
Underwriter against payment to or upon the order of the Company of the purchase

and place specified pursuant to this Agreement is a further condition of the
obligation of each Underwriter hereunder. Upon delivery, the Firm Shares shall
be registered in such names and in such denominations as the 

                                       8

time, on the business day prior to the First Delivery Date.

     At any time on or before the thirtieth day after the date of this
Agreement, the option granted in Section 2 may be exercised by written notice
being given to the Company by the Representatives. Such notice shall set forth
the aggregate number of Option Shares as to which the option is being exercised,
the names in which the Option Shares are to be registered, the denominations in
which the Option Shares are to be issued and the date and time, as determined by
the Representatives, when the Option Shares are to be delivered; provided,
however, that this date and time shall not be earlier than the First Delivery
Date nor earlier than the second business day after the date on which the option
shall have been exercised nor later than the fifth business day after the date
on which the option shall have been exercised. The date and time the Option
Shares are delivered are sometimes referred to as the "Second Delivery Date" and
the First Delivery Date and the Second Delivery Date are sometimes each referred
to as a "Delivery Date".

     Delivery of and payment for the Option Shares shall be made at the place
specified in the first sentence of the first paragraph of this Section 4 (or at
such other place as shall be determined by agreement between the Representatives
and the Company) at 10:00 a.m., New York City time, on the Second Delivery Date.
On the Second Delivery Date, the Company shall deliver or cause to be delivered
the certificates representing the Option Shares to the Representatives for the
account of each Underwriter against payment to or upon the order of the Company

delivery at the time and place specified pursuant to this Agreement is a further
condition of the obligation of each Underwriter hereunder. Upon delivery, the
Option Shares shall be registered in such names and in such denominations as the
Representatives shall request in the aforesaid written notice. For the purpose
of expediting the checking and packaging of the certificates for the Option
Shares, the Company shall make the certificates representing the Option Shares

          misleading.

               (iii) No facts have come to the attention of such counsel which

          respect to the patent position of the Company or any of its
          subsidiaries, or omit to state any material fact relating to the

          Company or any of its subsidiaries; such counsel has no knowledge of

<PAGE>   18

               (ii) No facts have come to the attention of such counsel which
          would form a basis for the belief that (a) the Registration Statement
          or any amendment thereto or (b) the Prospectus, as amended or
          supplemented, contain any untrue statement of a material fact, or omit
          to state any material fact, which is necessary to make the statements

Representatives a certificate, dated such Delivery Date, of its Chairman of the
Board, its President or a Vice President and its Chief Financial Officer stating
that:

               (i) The representations and warranties of the Company contained
          in this Agreement are true and correct as of such Delivery Date, and
          the Company has complied with all agreements and satisfied all
          conditions on its part to be complied with or satisfied prior to such
          Delivery Date; and the conditions set forth in Sections 7(a) and 7(m)
          have been fulfilled; and

               (ii) They have carefully examined the Registration Statement and
          the Prospectus and, in their opinion (A) as of the Effective Date, the
          Registration Statement and Prospectus did not include any untrue
          statement of a material fact and did not omit to state a material fact
          required to be stated therein or necessary to make the statements
          therein not misleading, and (B) since the Effective Date no event has
          occurred which should have been set forth in a supplement or amendment

certificates as you or counsel for the Underwriters may reasonably request.

forth or contemplated in the Prospectus or (ii) since such date there shall not
have been any change in the capital stock or long-term debt of the Company or
any of its subsidiaries or any change, or any development involving a
prospective change, in or affecting the general affairs, management, financial
position, stockholders' equity or results of operations of the Company and its
subsidiaries, otherwise than as set forth or contemplated in the Prospectus, the
effect of which, in any such case described in clause (i) or (ii), is, in the
judgment of the Representatives, so material and adverse as to make it
impracticable or inadvisable to proceed with the public offering or the delivery
of the Shares being delivered on such Delivery Date on the terms and in the
manner contemplated in the Prospectus.

          (n) Subsequent to the execution and delivery of this Agreement there
shall not have occurred any of the following: (i) trading in securities
generally on the New York Stock Exchange or the American Stock Exchange or in

adverse change in general economic, political or financial conditions (or the
effect of international conditions on the financial markets in the United States
shall be such) as to make it, in the judgment of a majority in interest of the
Underwriters, impracticable or inadvisable to proceed with the public offering
or delivery of the Shares being delivered on such Delivery Date on the terms and
in the manner contemplated in the Prospectus.

          (o) The American Stock Exchange shall have approved the Shares for
listing, subject only to official notice of issuance.

     All such opinions, letters, evidence, certificates and documents shall be
in compliance with the provisions of this Agreement only if they are
satisfactory in form and substance to you and counsel for the Underwriters. The
Company shall furnish to you conformed copies of such opinions, letters,
evidence, certificates and documents in such number as you shall reasonably
request. If any of the conditions specified in this Section 7 shall not have
been fulfilled when and as required by this Agreement, the Agreement and all
obligations of the Underwriters hereunder may be canceled at, or prior to, each
Delivery date, by you. Any such cancellation shall be without liability of the
Underwriters to the Company. Notice of such cancellation shall be given to the
Company in writing, or by telecopy or telephone confirmed in writing.

     8.   Indemnification and Contribution.

          (a) The Company shall indemnify and hold harmless each Underwriter
(including any Underwriter in its role as a qualified independent underwriter
pursuant to the rules of the National Association of Securities Dealers, Inc.),
its officers and employees and each person, if any, who controls any Underwriter
within the meaning of the Securities Act, from and against any loss, claim,
damage or liability, joint or several, or any action in respect thereof
(including, but not limited to, any loss, claim, damage, liability or action
relating to purchases and sales of Shares), to which that Underwriter, officer,
employee or controlling person may become subject, under the Securities Act or
otherwise, insofar as such loss, claim, damage, liability or action arises out
of, or is based upon, (i) any untrue statement or alleged untrue statement of a
material fact contained (A) in any Preliminary Prospectus, the Registration
Statement or the Prospectus or in any amendment or supplement thereto or (B) in
any blue sky application or other document prepared or executed by the Company
(or based upon any written information furnished by the Company) specifically
for the purpose of qualifying any or all of the Shares under the securities laws
of any state or other jurisdiction (any such application, document or
information being hereinafter called a "Blue Sky Application"), (ii) the
omission or alleged omission to state in any Preliminary Prospectus, the
Registration Statement or the Prospectus, or in any amendment or supplement
thereto, or in any Blue Sky Application any material fact required to be stated
therein or necessary to make the statements therein not misleading or (iii) any
act or failure to act or any alleged act or failure to act by any Underwriter in
connection with, or relating in any manner to, the Shares or the offering
contemplated hereby, and which is included as part of or referred to in any
loss, claim, damage, liability or action arising out of or based upon matters
covered by clause (i) or (ii) above (provided that the Company shall not be
liable under this clause (iii) to the extent that it is determined in a final
judgment by a court of competent jurisdiction that such loss, claim, damage,
liability or action resulted directly from any such acts or failures to act
undertaken or omitted to be taken by such Underwriter through its gross
negligence or willful misconduct), and shall reimburse each Underwriter and each
such officer, employee or controlling person promptly upon demand for any 

                                       20


<PAGE>   21

legal or other expenses reasonably incurred by that Underwriter, officer,
employee or controlling person in connection with investigating or defending or
preparing to defend against any such loss, claim, damage, liability or action as
such expenses are incurred; provided, however, that the Company shall not be
liable in any such case to the extent that any such loss, claim, damage,
liability or action arises out of, or is based upon, any untrue statement or
alleged untrue statement or omission or alleged omission made in any Preliminary
Prospectus, the Registration Statement or the Prospectus, or in any such
amendment or supplement, or in any Blue Sky Application, in reliance upon and in
conformity with written information concerning such Underwriter furnished to the
Company through the Representatives by or on behalf of any Underwriter
specifically for inclusion therein; and provided further, that the foregoing
indemnity agreement is subject to the condition that, insofar as it relates to
any untrue statement, alleged untrue statement, omission or alleged omission
made in any Preliminary Prospectus but eliminated or remedied in the Prospectus,
such indemnity agreement shall not inure to the benefit of any Underwriter from
whom the person asserting any loss, claim, damage or liability purchased the
Shares which are the subject thereof (or to the benefit of any person who
controls such Underwriter) if a copy of the Prospectus was not sent or given to
such person with or prior to the written confirmation of the sale of such Shares
to such person. The foregoing indemnity agreement is in addition to any
liability which the Company may otherwise have to any Underwriter or to any
officer, employee or controlling person of that Underwriter.

          (b) Each Underwriter, severally and not jointly, shall indemnify and
hold harmless the Company, its officers and employees, each of its directors
(including any person who, with his or her consent, is named in the Registration
Statement as about to become a director of the Company), and each person, if
any, who controls the Company within the meaning of the Securities Act or
otherwise, from and against any loss, claim, damage or liability, joint or
several, or any action in respect thereof, to which the Company or any such
director, officer or controlling person may become subject, under the Securities
Act or otherwise, insofar as such loss, claim, damage, liability or action
arises out of, or is based upon, (i) any untrue statement or alleged untrue
statement of a material fact contained (A) in any Preliminary Prospectus, the
Registration Statement or the Prospectus or in any amendment or supplement
thereto, or (B) in any Blue Sky Application or (ii) the omission or alleged
omission to state in any Preliminary Prospectus, the Registration Statement or
the Prospectus, or in any amendment or supplement thereto, or in any Blue Sky
Application any material fact required to be stated therein or necessary to make
the statements therein not misleading, but in each case only to the extent that
the untrue statement or alleged untrue statement or omission or alleged omission
was made in reliance upon and in conformity with written information concerning
such Underwriter furnished to the Company through the Representatives by or on
behalf of that Underwriter specifically for inclusion therein, and shall
reimburse the Company and any such director, officer or controlling person for
any legal or other expenses reasonably incurred by the Company or any such
director, officer or controlling person in connection with investigating or
defending or preparing to defend against any such loss, claim, damage, liability
or action as such expenses are incurred. The foregoing indemnity agreement is in
addition to any liability which any Underwriter may otherwise have to the
Company or any such director, officer, employee or controlling person.

          (c) Promptly after receipt by an indemnified party under this Section
8 of notice of any claim or the commencement of any action, the indemnified
party shall, if a claim in respect thereof is to be made against the
indemnifying party under this Section 8, notify the 

                                       21
<PAGE>   22

indemnifying party in writing of the claim or the commencement of that action;
provided, however, that the failure to notify the indemnifying party shall not
relieve it from any liability which it may have under this Section 8 except to
the extent it has been materially prejudiced by such failure and, provided
further, that the failure to notify the indemnifying party shall not relieve it
from any liability which it may have to an indemnified party otherwise than
under this Section 8. If any such claim or action shall be brought against an
indemnified party, and it shall notify the indemnifying party thereof, the
indemnifying party shall be entitled to participate therein and, to the extent
that it wishes, jointly with any other similarly notified indemnifying party, to
assume the defense thereof with counsel reasonably satisfactory to the
indemnified party. After notice from the indemnifying party to the indemnified
party of its election to assume the defense of such claim or action, the
indemnifying party shall not be liable to the indemnified party under this
Section 8 for any legal or other expenses subsequently incurred by the
indemnified party in connection with the defense thereof other than reasonable
costs of investigation; provided, however, that the Representatives shall have
the right to employ counsel to represent jointly the Representatives and those
other Underwriters and their respective officers, employees and controlling
persons who may be subject to liability arising out of any claim in respect of
which indemnity may be sought by the Underwriters against the Company under this
Section 8 if, in the reasonable judgment of the Representatives, it is advisable
for the Representatives and those Underwriters, officers, employees and
controlling persons to be jointly represented by separate counsel, and in that
event the fees and expenses of such separate counsel shall be paid by the
Company. No indemnifying party shall (i) without the prior written consent of
the indemnified parties (which consent shall not be unreasonably withheld),
settle or compromise or consent to the entry of any judgment with respect to any
pending or threatened claim, action, suit or proceeding in respect of which
indemnification or contribution may be sought hereunder (whether or not the
indemnified parties are actual or potential parties to such claim or action)
unless such settlement, compromise or consent includes an unconditional release
of each indemnified party from all liability arising out of such claim, action,
suit or proceeding, or (ii) be liable for any settlement of any such action
effected without its written consent (which consent shall not be unreasonably
withheld), but if settled with the consent of the indemnifying party or if there
be a final judgment of the plaintiff in any such action, the indemnifying party
agrees to indemnify and hold harmless any indemnified party from and against any
loss or liability by reason of such settlement or judgment.

          (d) If the indemnification provided for in this Section 8 shall for
any reason be unavailable to or insufficient to hold harmless an indemnified
party under Section 8(a) or 8(b) in respect of any loss, claim, damage or
liability, or any action in respect thereof, referred to therein, then each
indemnifying party shall, in lieu of indemnifying such indemnified party,
contribute to the amount paid or payable by such indemnified party as a result
of such loss, claim, damage or liability, or action in respect thereof, (i) in
such proportion as shall be appropriate to reflect the relative benefits
received by the Company on the one hand and the Underwriters on the other from
the offering of the Shares or (ii) if the allocation provided by clause (i)
above is not permitted by applicable law, in such proportion as is appropriate
to reflect not only the relative benefits referred to in clause (i) above but
also the relative fault of the Company on the one hand and the Underwriters on
the other with respect to the statements or omissions which resulted in such
loss, claim, damage or liability, or action in respect thereof, as well as any
other relevant equitable considerations. The relative benefits received by the
Company on the one hand and the Underwriters on the other with respect to such
offering shall be deemed to be in the same proportion as the total net proceeds
from the offering of the Shares purchased under this Agreement 

                                       22


<PAGE>   23

(before deducting expenses) received by the Company on the one hand, and the
total underwriting discounts and commissions received by the Underwriters with
respect to the shares of the Shares purchased under this Agreement, on the other
hand, bear to the total gross proceeds from the offering of the shares of the
Shares under this Agreement, in each case as set forth in the table on the cover
page of the Prospectus. The relative fault shall be determined by reference to
whether the untrue or alleged untrue statement of a material fact or omission or
alleged omission to state a material fact relates to information supplied by the
Company or the Underwriters, the intent of the parties and their relative
knowledge, access to information and opportunity to correct or prevent such
statement or omission. The Company and the Underwriters agree that it would not
be just and equitable if contributions pursuant to this Section 8 were to be
determined by pro rata allocation (even if the Underwriters were treated as one
entity for such purpose) or by any other method of allocation which does not
take into account the equitable considerations referred to herein. The amount
paid or payable by an indemnified party as a result of the loss, claim, damage
or liability, or action in respect thereof, referred to above in this Section 8
shall be deemed to include, for purposes of this Section 8(d), any legal or
other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this Section 8(d), no Underwriter shall be required to contribute
any amount in excess of the amount by which the total price at which the Shares
underwritten by it and distributed to the public were offered to the public
exceeds the amount of any damages which such Underwriter has otherwise paid or
become liable to pay by reason of any untrue or alleged untrue statement or
omission or alleged omission. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. The Underwriters' obligations to contribute as provided in
this Section 8(d) are several in proportion to their respective underwriting
obligations and not joint.

          (e) The Underwriters severally confirm and the Company acknowledges
that the statements with respect to the public offering of the Shares by the
Underwriters set forth on the cover page of, the legend concerning
over-allotments on the inside front cover page of and the concession and
reallowance figures appearing under the caption "Underwriting" in, the
Prospectus are correct and constitute the only information concerning such
Underwriters furnished in writing to the Company by or on behalf of the
Underwriters specifically for inclusion in the Registration Statement and the
Prospectus.

     9.   Defaulting Underwriters. If, on either Delivery Date, any Underwriter
defaults in the performance of its obligations under this Agreement, the
remaining non-defaulting Underwriters shall be obligated to purchase the Shares
which the defaulting Underwriter agreed but failed to purchase on such Delivery
Date in the respective proportions which the number of the Firm Shares set
opposite the name of each remaining non-defaulting Underwriter in Schedule 1
hereto bears to the total number of the Firm Shares set opposite the names of
all the remaining non-defaulting Underwriters in Schedule 1 hereto; provided,
however, that the remaining non-defaulting Underwriters shall not be obligated
to purchase any of the Shares on such Delivery Date if the total number of
Shares which the defaulting Underwriter or Underwriters agreed but failed to
purchase on such date exceeds 9.09% of the total number of Shares to be
purchased on such Delivery Date, and any remaining non-defaulting Underwriter
shall not be obligated to purchase more than 110% of the number of Shares which
it agreed to purchase on such Delivery Date pursuant to the terms of Section 2.
If the foregoing maximums are exceeded, the remaining non-defaulting
Underwriters, 

                                       23


<PAGE>   24

or those other underwriters satisfactory to the Representatives who so agree,
shall have the right, but shall not be obligated, to purchase, in such
proportion as may be agreed upon among them, all the Shares to be purchased on
such Delivery Date. If the remaining non-defaulting Underwriters or other
underwriters satisfactory to the Representatives do not elect to purchase the
shares which the defaulting Underwriter or Underwriters agreed but failed to
purchase on such Delivery Date, this Agreement (or, with respect to the Second
Delivery Date, the obligation of the Underwriters to purchase, and of the
Company to sell, the Option Shares) shall terminate without liability on the
part of any non-defaulting Underwriter or the Company, except that the Company
will continue to be liable for the payment of expenses to the extent set forth
in Sections 6 and 11. As used in this Agreement, the term "Underwriter"
includes, for all purposes of this Agreement unless the context requires
otherwise, any party not listed in Schedule 1 hereto who, pursuant to this
Section 9, purchases Firm Shares which a defaulting Underwriter agreed but
failed to purchase.

     Nothing contained herein shall relieve a defaulting Underwriter of any
liability it may have to the Company for damages caused by its default. If other
underwriters are obligated or agree to purchase the Shares of a defaulting or
withdrawing Underwriter, either the Representatives or the Company may postpone
the Delivery Date for up to seven full business days in order to effect any
changes that in the opinion of counsel for the Company or counsel for the
Underwriters may be necessary in the Registration Statement, the Prospectus or
in any other document or arrangement.

     10.  Termination. The obligations of the Underwriters hereunder may be
terminated by the Representatives by notice given to and received by the Company
prior to delivery of and payment for the Firm Shares if, prior to that time, any
of the events described in Sections 7(m) or 7(n), shall have occurred or if the
Underwriters shall decline to purchase the Shares for any reason permitted under
this Agreement.

     11.  Reimbursement of Underwriters' Expenses. If the Company shall fail to
tender the Shares for delivery to the Underwriters by reason of any failure,
refusal or inability on the part of the Company to perform any agreement on its
part to be performed, or because any other condition of the Underwriters'
obligations hereunder required to be fulfilled by the Company is not fulfilled,
the Company will reimburse the Underwriters for all reasonable out-of-pocket
expenses (including fees and disbursements of counsel) incurred by the
Underwriters in connection with this Agreement and the proposed purchase of the
Shares, and upon demand (accompanied by reasonable documentation of such
expenses) the Company shall pay the full amount thereof to the Representatives.
If this Agreement is terminated pursuant to Section 9 by reason of the default
of one or more Underwriters, the Company shall not be obligated to reimburse any
defaulting Underwriter on account of those expenses.

     12.  Notices, etc. All statements, requests, notices and agreements
hereunder shall be in writing, and:

          (a) if to the Underwriters, shall be delivered or sent by mail, telex

delivered or sent by mail, telex or facsimile transmission to such Underwriter
at its address set forth in its acceptance telex to the Representatives, which
address will be supplied to any other party hereto by the Representatives upon
request. Any such statements, requests, notices or agreements shall take effect
at the time of receipt thereof. The Company shall be entitled to act and rely
upon any request, consent, notice or agreement given or made on behalf of the
Underwriters by the Representatives.

     13.  Persons Entitled to Benefit of Agreement. This Agreement shall inure
to the benefit of and be binding upon the Underwriters, the Company and their
respective successors. This Agreement and the terms and provisions hereof are
for the sole benefit of only those persons, except that (A) the representations,
warranties, indemnities and agreements of the Company contained in this
Agreement shall also be deemed to be for the benefit of the person or persons,
if any, who control any Underwriter within the meaning of Section 15 of the
Securities Act and (B) the indemnity agreement of the Underwriters contained in
Section 8(b) of this Agreement shall be deemed to be for the benefit of
directors of the Company, officers of the Company who have signed the
Registration Statement and any person controlling the Company within the meaning
of Section 15 of the Securities Act. Nothing in this Agreement is intended or
shall be construed to give any person, other than the persons referred to in
this Section 13, any legal or equitable right, remedy or claim under or in
respect of this Agreement or any provision contained herein.

     14.  Survival. The respective indemnities, representations, warranties and
agreements of the Company and the Underwriters contained in this Agreement or
made by or on behalf on them, respectively, pursuant to this Agreement, shall
survive the delivery of and payment for the Shares and shall remain in full
force and effect, regardless of any investigation made by or on behalf of any of
them or any person controlling any of them.

     15.  Definition of the Terms "Business Day" and "Subsidiary". For purposes
of this Agreement, (a) "business day" means any day on which the New York Stock
Exchange, Inc. is open for trading and (b) "subsidiary" has the meaning set
forth in Rule 405 of the Rules and Regulations.

     16.  Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of New York.

     17.  Counterparts. This Agreement may be executed in one or more
counterparts and, if executed in more than one counterpart, the executed
counterparts shall each be deemed to be an original but all such counterparts
shall together constitute one and the same instrument.

     18.  Headings. The headings herein are inserted for convenience of
reference only and are not intended to be part of, or to affect the meaning or
interpretation of, this Agreement.

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


     Selfcare, Inc., a corporation organized and existing under the laws of the
State of Delaware (the "Corporation"), does hereby certify:

     That, pursuant to authority conferred upon the Board of Directors of the
Corporation by the Amended and Restated Certificate of Incorporation of said
Corporation, as amended, and pursuant to the provisions of Section 151 of Title
8 of the Delaware Code of 1953, said Board of Directors, at a meeting duly held
on October 10, 1996, adopted a resolution providing for the designations,
preferences and relative, participating, optional or other rights, and the
qualifications, limitations or restrictions thereof, of a series of preferred
stock, which resolution is as follows:

     RESOLVED, that pursuant to the authority vested in the Board of Directors
of the Corporation in accordance with the provisions of the Amended and Restated
Certificate of Incorporation of the Corporation, a series of preferred stock of
the Corporation known as Series A Convertible Preferred Stock be, and it hereby
is, created, classified, and authorized, and the issuance thereof is provided
for, and that the designation and number of shares, and relative rights,
preferences and limitations thereof, shall be as set forth in the form appended
hereto as Exhibit A.



<PAGE>   2

                                                                       EXHIBIT A

     Section 1. Designation.
                -----------

     The shares of the series of Preferred Stock shall be designated as "Series
A Convertible Preferred Stock," and the number of shares constituting such
series shall be 10,000. The par value of the Series A Convertible Preferred
Stock shall be $.001 per share.

     Section 2. Dividends.
                ---------

          (a) The holders of outstanding shares of Series A Convertible
Preferred Stock shall be entitled to receive, when, as and if declared by the
Board of Directors, out of funds legally available for the payment of dividends,
dividends at the rate per share of 6% of the initial purchase price paid for
such shares (the "Purchase Price") per annum. All dividends shall be cumulative
and shall be payable in cash in arrears on each January 15, April 15, July 15
and October 15 (each such date, a "Dividend Payment Date") commencing on January
15, 1997, in preference to and with priority over dividends on the common stock
of the Corporation, par value $.001 per share, (the "Common Stock"). Such
quarterly dividends shall be cumulative and shall accrue (whether or not earned
or declared, and whether or not there are fund legally available therefor)
without interest from the first day of the quarterly period in which such
dividend may be payable as herein provided. Notwithstanding the foregoing, in
the event that the closing bid price of the Common Stock on the American Stock
Exchange (or, in the event that such security is not traded on the American
Stock Exchange, such other national or regional securities exchange or automated
quotation system upon which such security is listed and principally traded or,
if no such price is available, the per share market value of such security as
determined by a nationally recognized investment banking firm or other
nationally recognized financial adviser retained by Seller for such purpose)
during any thirty (30) consecutive calendar days is equal to or greater than
$20.00 per share, the dividends provided for herein shall cease to accrue
following such 30-day period.

          (b) All dividends paid with respect to shares of the Series A
Convertible Preferred Stock pursuant to Section 2(a) hereof shall be paid pro
rata to the holders entitled thereto. Any such unpaid dividends shall be in
arrears until paid.

          (c) Whenever dividends on the Series A Convertible Preferred Stock are
in arrears, the Corporation shall not declare dividends on or make any other
distribution in respect of the Common Stock.

          (d) The amount of dividends accrued on the Series A Convertible
Preferred Stock for any period less than a full quarterly dividend period
(including the initial dividend period) shall be equal to a pro rata portion of
the total dividend payable for the quarterly dividend period during which such
period occurs, based on the actual number of days elapsed in such period and the
total number of days in the applicable quarterly dividend period. Dividends
shall accrue on a daily basis during each dividend period as provided above, and
the

                                        2

<PAGE>   3



Liquidation Preference (as defined below) of each outstanding share of Series A
Convertible Preferred Stock shall be correspondingly increased on a daily basis.
Each such dividend shall be payable to holders of record as their names shall
appear on the stock books of the Corporation on any record date for such
dividends, except that dividends in arrears for any past Dividend Payment Date
may be declared and paid at any time without reference to such regular Dividend
Payment Date to holders of record on such date not more than sixty (60) days or
less then ten (10) days prior to the date of payment as shall be determined by
the Board of Directors.

     Section 3. Liquidation Preference.
                ----------------------

          (a)  Preference.
               ----------

               (i) In the event of any liquidation, dissolution or winding up of
the Corporation, either voluntarily or involuntarily, the holders of the Series
A Convertible Preferred Stock shall be entitled to receive prior and in
preference to any distribution of any of the assets or surplus funds of the
Corporation to the holders of Common Stock of the Corporation, an amount equal
to the sum of (A) the Purchase Price (which shall be $1,000 per share), plus (B)
a further amount equal to any dividends on such shares as to which holders of
the Series A Convertible Preferred Stock are entitled pursuant to Section 2 that
have not been paid (such sum, the "Liquidation Preference"). If, upon such

                          GRANT OF RIGHTS; EXCLUSIVITY

         2.1 LICENSE GRANTS TO SELFCARE.

                  (a) Subject to the terms and conditions of this Agreement,
ChemTrak hereby grants to Selfcare a license under the ChemTrak Technology to
offer and sell the HIV Product in the Territory, including but not limited to
the right to perform HIV testing, and to use the Software solely for the purpose
of performing such testing, at a Testing Facility for purchasers of the HIV
Product, for the term of this Agreement. This license shall be exclusive except
as otherwise provided in Section 2.3 below. Selfcare may sublicense or otherwise
transfer such rights (without the right to grant further sublicenses or
otherwise transfer such rights) to third parties only with ChemTrak's prior
written consent, which shall not be unreasonably withheld. Selfcare will provide
ChemTrak with a complete copy of the proposed sublicense agreement at the time
Selfcare solicits ChemTrak's consent to the sublicense.

                  (b) As a condition of the license rights set forth in this
Agreement, Selfcare shall use the Software in connection with all HIV testing in
the Territory unless the parties mutually agree that a modified version of the
Software will be used. Selfcare shall not copy the Software in any manner,
except that Selfcare may make one working copy, and one copy for back-up
purposes, for each Testing Facility. Selfcare shall not distribute or provide
the Software or any copy thereof to any third party without the prior written
consent of ChemTrak. Further, Selfcare shall not modify the Software in any way,
including without limitation by making any localizations, without the prior
written consent of ChemTrak, which consent shall not be unreasonably withheld.
Selfcare shall not reverse engineer or reverse compile the Software and shall
not use the Software in any manner other than pursuant to the license granted
above in this Section 2.1(b). Immediately upon the expiration or any termination
of this Agreement or at a later time specified by ChemTrak, Selfcare shall
return all copies of the Software to ChemTrak and make no further use of the
Software.

                  (c) Subject to the terms and conditions of this Agreement,
ChemTrak hereby grants to Selfcare an exclusive license to use the mark
Aware(TM) in connection with the offer, sale and distribution of the HIV Product
in the Territory for the term of this Agreement. As a condition of the license
rights set forth in this Agreement, Selfcare agrees that the Aware(TM) mark
shall be used in connection with such activities and no other marks, including
the ChemTrak(R) mark, shall be used unless the parties mutually agree on such
use in advance. ChemTrak shall retain ownership of and all rights in the
Aware(TM) mark and shall own and retain all rights in any alternative or
additional brand name(s) which the parties may agree to use (collectively, the
"MARKS"). In order to assure the quality of goods marketed under the Marks,
ChemTrak shall have the right to



                                       4.

                            [CONFIDENTIAL TREATMENT]
    

inspect Selfcare's facilities during normal business hours, after giving
reasonable notice of such intent. Selfcare shall conduct its business in a
manner which will enhance the reputation and goodwill attached to the Marks, and
all goodwill shall inure to the benefit of ChemTrak as owner of the Marks.

                  (d) Selfcare agrees to use the ChemTrak Technology and the
Marks only to offer, sell and distribute the HIV Product in the Territory for
the term of this Agreement and not for any other purpose.

   
         2.2 COVENANT NOT TO SELL COMPETITIVE PRODUCTS. Selfcare hereby
covenants not to market, sell or distribute, directly or indirectly through one
or more third parties, any mail-in HIV blood test product other than the HIV
Product in any country in the Territory where Selfcare has an exclusive license
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX provided, however, that this
covenant will not apply in the event that this Agreement is terminated by
Selfcare pursuant to Section 10.3 for ChemTrak's material breach of this
Agreement. The restriction on the sale of mail-in HIV blood tests does not apply
to mail-in urine or saliva tests. Selfcare hereby acknowledges that the ChemTrak
Technology, particularly ChemTrak's proprietary Software and the data and
regulatory strategy reflected in ChemTrak's filings with the U.S. FDA regarding
the HIV Product, has been maintained by ChemTrak as highly confidential and
constitutes ChemTrak's proprietary and extremely valuable trade secret
information. Selfcare further acknowledges that it has not previously engaged in
development or marketing of any mail-in HIV test product, and the ChemTrak
Technology confers upon Selfcare a substantial competitive advantage in
obtaining regulatory approval and market acceptance of a mail-in HIV test
product in the Territory. Accordingly, Selfcare and ChemTrak each acknowledge
and agree that the XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX is
reasonable and necessary to protect the commercial value of ChemTrak's
proprietary trade secrets provided to Selfcare under this Agreement.
    

         2.3 LOSS OF EXCLUSIVITY. ChemTrak will have the option, upon ninety
(90) days advance written notice, to convert Selfcare's exclusive rights to
offer, sell and distribute the HIV Product in each country in the Territory into
non-exclusive rights in any of the following events:

                  (a) Selfcare fails to file for Regulatory Approval in such
country by a date determined as follows. Set forth on Exhibit C are projected
dates by which the parties expect Selfcare will file for regulatory approval to
commercially sell the HIV Product in the major European countries listed on
Exhibit C. If at any time Selfcare believes that it will likely not be able to
make such a filing by such date, then Selfcare shall immediately notify ChemTrak
and the parties shall meet and confer regarding the reasons for such delay and
available means to expedite such filings. The parties will seek to mutually


                                       5.

   
                     Material Omitted and Filed Separately
                  with the Securities and Exchange Commission.
    
<PAGE>   10
   
                            [Confidential Treatment]
    


agree on a plan and new timetable for making such filing. If the parties are
unable to agree on such a plan and timetable, then ChemTrak will have the option
to convert Selfcare's rights in such country to non-exclusive effective six (6)
months after the date set forth on Exhibit C if Selfcare has not made the
required regulatory filing by the end of such 6-month period.

                  (b) Selfcare fails to launch a commercially reasonable
marketing campaign designed to generate substantial demand for HIV Products and
commence commercial sales of the HIV Product in such country within six (6)
months after receiving Regulatory Approval in such country.

   
                  (c) Selfcare's market share for the HIV Product in such
country, as measured on the second and each subsequent anniversary of the date
of Selfcare's first commercial sale of an HIV Product in such country, is less
than XXXXXXXXXXXXXXXXXXX of the percentage of the market that each competitor
would have if all had equal market share. For example, if as of such anniversary
there are three competitors in the market, then ChemTrak may convert the license
to non-exclusive if Selfcare's market share is less than XXXXXXXXXXXXXXXXXXXX as
of such date XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX. For purposes of this paragraph, the
relevant market shall consist of all mail-in HIV blood tests, and each separate
brand shall constitute one competitor in the market. In order to enable ChemTrak
to calculate market share, Selfcare shall provide ChemTrak upon request with all
relevant information available to Selfcare.
    

         2.4 SELFCARE AFFILIATES.

                  (a) All costs, expenses, revenues and proceeds incurred or
received by any Selfcare Affiliate shall be deemed to be incurred or received by
Selfcare for purposes of all financial calculations and obligations under this
Agreement. Notwithstanding any other terms of this Agreement, the Parties agree
that all payments due from Selfcare to ChemTrak hereunder shall be made by
Selfcare and not any Selfcare Affiliate.

                  (b) The Parties agree that the goals with respect to non-U.S.
income or withholding tax liability shall be to minimize the aggregate amount of
non-U.S. income and withholding tax liabilities incurred by the Parties
collectively with respect to commercialization of the HIV Product in the
Territory, and to allocate such tax burdens equally between the Parties as
provided herein. In that regard:

                           (i) If any non-U.S. income or withholding tax
liability is incurred by either Party with respect to operations conducted
pursuant to this Agreement (e.g., such Party could not avoid the tax liability
by applying current operating losses or net operating loss carryforwards
resulting from operations related to the sale of the HIV

Product pursuant to the Agreement), then (A) when Selfcare incurs the non-U.S.
tax liability, the full amount of such liability shall be xxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxx, and (B) when ChemTrak incurs the non-U.S. tax
liability, the full amount of such liability shall be xxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxx. The Parties acknowledge that any tax credit related to
the HIV Product will xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx if the tax credit is used by Selfcare to
avoid paying taxes in any jurisdiction for operations related to the sale of HIV
Products pursuant to this Agreement.
    

                           (ii) The Parties also agree that each may either (A)
avoid potential non-U.S. income or withholding tax liability by applying current
operating losses and net operating loss carry forwards that result from its
operations with respect to the HIV Product, and/or (B) avoid paying non-U.S.
income or withholding taxes by applying tax credits resulting from operations
with respect to the HIV Product.

   
                           (iii) If either Party could apply any tax credits
arising in any jurisdiction other than the United States related to the HIV
Product against income in any jurisdiction that is not related to the sale of
HIV Products pursuant to this Agreement, then it shall promptly notify the other
Party. The Parties agree to meet with each other along with their tax advisors
and to take all commercially reasonable steps to permit such credit to be used
by one Party and to permit the other Party to obtain XXXXXXXXXXXXXXXXXXXX of
such credit.
    

                                    ARTICLE 3
                         DEVELOPMENT OF THE HIV PRODUCT

         3.1 GENERAL RESPONSIBILITIES. Selfcare shall have sole responsibility
for diligently pursuing Regulatory Approval of the HIV Product throughout the
Territory as soon as practicable, and for bearing all costs associated
therewith. Selfcare shall prepare, file and pursue diligently all regulatory

provide Selfcare with a copy of all documentation required by the U.S. FDA in
connection with its review of the HIV Product, including a right to reference
all applications, registrations, and supporting documents submitted and received
by ChemTrak, and will provide assistance in connection with the pursuit of
Regulatory Approvals in the Territory according to a plan to be mutually agreed
upon. Such assistance will be provided without charge to Selfcare. Selfcare
shall have the right to use such information solely for the purpose of pursuing
Regulatory Approvals and commercializing HIV Products in the Territory during
the term of this Agreement; provided, however, that ChemTrak will provide
Selfcare access to this information after the termination or expiration of this
Agreement to permit Selfcare to comply with regulatory requirements applicable
to HIV Products sold by Selfcare during the term of this Agreement and to defend
against product liability and other suits pertaining to such


                                       7.

days notice if ChemTrak fails to obtain Regulatory Approval in the United States
within XXXXXX of the Effective Date.

         3.2 TESTING FACILITIES; COUNSELING SERVICE. Prior to obtaining the
first Regulatory Approval in the Territory, Selfcare shall establish or contract
for a single central laboratory (or more as Selfcare determines is reasonable or
necessary) to conduct HIV testing in accordance with the protocols and
procedures described in ChemTrak's submissions to the U.S. FDA or amended, as
required by a country's regulatory authorities, (a "TESTING FACILITY"). ChemTrak
shall provide Selfcare with a copy of the Software for use at each such facility
for the processing of HIV Tests during the term of this Agreement. At such time
Selfcare shall also establish a counseling service to report results to
customers and provide appropriate counseling regarding the results, again as
provided in ChemTrak's submissions to FDA or amended, as required by a country's
regulatory authorities, (the "COUNSELING SERVICE"). Selfcare shall bear all
costs associated with establishing the Testing Facilities and the Counseling
Service, including any additional requirements of the countries in the
Territory. ChemTrak shall have the right to inspect the Testing Facilities and
Counseling Service during normal business hours (after giving reasonable notice)
in order to ensure that each is operating in the manner described in ChemTrak's
FDA documentation or amended, as required by a country's regulatory authorities,
and in accordance with all applicable regulatory standards.

   
         3.3 CLINICAL TRIALS SUPPLY. Subject to the terms of this Agreement,
ChemTrak shall use diligent efforts to supply or cause to be supplied to
Selfcare, and Selfcare shall purchase from ChemTrak, Selfcare's requirements of
Sample Collection Kits for use in Territory Development activities, including
clinical studies. ChemTrak will provide such product units to Selfcare for a
purchase price equal to XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX; provided
that such product units are made available to study subjects for XXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX. If the
compensation paid exceeds such amount, the Parties shall mutually determine an
appropriate purchase price for such product units.

                  (a) Within 90 days following the Effective Date, Selfcare
shall prepare a detailed plan describing activities to be undertaken to pursue
Regulatory Approvals for the HIV Product in the Territory and to establish the
Testing Facilities and Counseling Service. ChemTrak shall have the right to
review and comment on such plan before Selfcare makes any contact with any
regulatory agency pertaining to the HIV Product in the Territory. Once agreed
between the parties, Selfcare shall conduct its regulatory activities regarding
the HIV Product as provided in the plan. However, Selfcare reserves the right to
modify the plan, as required by regulatory circumstances, following consultation
with ChemTrak.

                  (b) Selfcare shall report to ChemTrak at least once each
calendar quarter, but not later than thirty (30) days following the end of such
calendar quarter, on the progress of such activities. Selfcare will notify
ChemTrak as soon as practicable in the event of any substantial changes in the
development activities described in the plan and in the event any Regulatory
Approval is received for any country in the Territory.

         3.5 PUBLICATIONS. Selfcare and ChemTrak shall cooperate in the
preparation and publication of papers in support of development and marketing
activities in the Territory. Neither Party shall present, publish or otherwise
disclose any information regarding the HIV Product in the Territory except with
the prior written consent of the other. Each party shall make available to the
other at no cost a copy of any publications or other marketing support materials
which such Party produces for its purposes.

                        SUPPLY OF SAMPLE COLLECTION KITS

         4.1 PURCHASES OF SAMPLE COLLECTION KITS. Subject to the terms of this
Agreement, ChemTrak shall use diligent efforts to supply Selfcare, and Selfcare

                        [CONFIDENTIAL TREATMENT]
    

ChemTrak shall use diligent efforts to deliver such Sample Collection Kits as
soon as practicable thereafter, but in no event longer than 60 days after the
date of such purchase order. Beginning on the first day of each calendar quarter
thereafter, Selfcare shall provide ChemTrak with a firm purchase order
specifying the number of Sample Collection Kits desired, on a monthly basis, for
the following quarter and a proposed shipment date for such units of no less
than 60 days from the date of such purchase order (each, a "Purchase Order").
ChemTrak will accept any such Purchase Order from Selfcare within five (5) days
after receipt of such Purchase Order at its principal place of business.

   
     4.3 PURCHASE PRICE; PAYMENT. Selfcare shall pay to ChemTrak a price
(the "PURCHASE PRICE") for purchase of Sample Collection Kits equal to
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX. ChemTrak shall
invoice Selfcare for such amount as of the date of shipment. All payments for

confirmed shipment for such Sample Collection Kits.
    

         4.4 DELIVERY.

                  (a) ChemTrak shall use diligent efforts, consistent with its
other shipment obligations and manufacturing capacity, to ship all Sample
Collection Kits ordered by Selfcare on or before the requested shipment date, to
the extent such date is at least fifteen (15) days after the date ChemTrak
accepts the Purchase Order for such shipment. The shipping and packaging method
used will be at the discretion of ChemTrak, subject to written approval of
Selfcare. Deliveries shall be made F.O.B. ChemTrak's facility (ICC Incoterms
1990) and shall be shipped to Selfcare's address as set forth in this Agreement,
or as otherwise directed by Selfcare in writing. All Sample Collection Kits will
be shipped by ChemTrak freight collect, or if prepaid, such freight will be
subsequently billed to Selfcare. If requested by Selfcare, ChemTrak will insure
the shipments against damage to or loss of Sample Collection Kits and will
subsequently bill Selfcare for such shipping insurance. Selfcare will reimburse
ChemTrak for shipping and insurance expenses, if any, within forty-five (45)
days after the date of such invoices. ChemTrak reserves the right to deliver in
advance of estimated delivery dates. Selfcare shall make any claims for damage
or loss in transit through the carrier and any insurance proceeds payable in
respect of any loss incurred shall be paid to Selfcare.

                  (b) If at any time ChemTrak is unable to supply total
worldwide demand for Sample Collection Kits, ChemTrak shall allocate available
Sample Collection Kits (or components thereof) to the Territory pro rata with
other markets outside the Territory based upon relative market share, as
measured by the most recent quarterly or annual sales figures for which data is
reasonably available.

                  (c) In the event that ChemTrak, whether by reason of Force
Majeure or otherwise, either (1) fails in any quarter to deliver to Selfcare at
least fifty percent (50%) of the amount of Sample Collection Kits ordered by
Selfcare or (2) fails in each of two consecutive quarters to deliver to Selfcare
at least eighty percent (80%) of the amounts ordered by Selfcare for each of
such quarters, notwithstanding the obligation of Selfcare to purchase from
ChemTrak all Sample Collection Kits, Selfcare shall be entitled for the duration
of the term of this Agreement to seek alternate sources of supply for the Sample
Collection Kits (or components thereof) to be used, sold or otherwise
distributed in the Territory pursuant to the license granted herein, and such
license shall be deemed to include such right. In particular, if Selfcare seeks
alternate sources for ChemTrak's proprietary finger stick device, Selfcare will
have a non-exclusive, worldwide license to make such devices or have them made
by a third party. In the event that Selfcare exercises its right to use
alternate sources of supply, the cost of securing Sample Collection Kits (or
components thereof) from alternate sources of supply shall be deemed to be a
Commercialization Cost.

         4.5 ACCEPTANCE. Selfcare shall inspect all Sample Collection Kit
shipments received from ChemTrak for visible damage promptly upon receipt
thereof at the shipping destination and may reject any Sample Collection Kit
Units which are damaged or fail to comply with the specification agreed by the
parties. Sample Collection Kits not rejected by written notification to ChemTrak
within sixty (60) days after receipt by Selfcare shall be deemed to have been
accepted. Rejected goods shall be returned freight prepaid to ChemTrak within
fifteen (15) days after rejection. As promptly as possible after receipt by
ChemTrak of properly rejected goods, ChemTrak shall, at ChemTrak's option, (i)
replace the rejected goods at ChemTrak's expense, or (ii) grant Selfcare a
credit for such rejected goods equal to the price paid therefor. Such
replacement or credit shall be ChemTrak's sole responsibility and obligation to
Selfcare for nonconforming Sample Collection Kits. The party shipping the goods
pursuant to this section shall bear the entire risk of loss for goods during
shipment. Any insurance proceeds payable in respect of any loss incurred shall
be paid to the party bearing the risk of loss for such goods to the extent of
the loss incurred. For properly rejected goods, ChemTrak will prepay
transportation charges back to Selfcare and shall reimburse Selfcare for any
reasonable costs of transportation for returning such goods; for all other
goods, Selfcare shall pay transportation charges in both directions.

                                    ARTICLE 5
                MARKETING, SALE AND DISTRIBUTION OF HIV PRODUCTS

         5.1 MARKETING EFFORTS. Selfcare agrees to use diligent efforts to
promote the sale, marketing and distribution of the HIV Products in the
Territory, including undertaking a commercially reasonable advertising campaign
in connection with the launch and sale of HIV Products. Selfcare shall provide
ChemTrak with a copy of its


                                      11.
<PAGE>   16
marketing plan as provided in Section 6.3 for ChemTrak's review and comment.
Selfcare agrees to consider in good faith ChemTrak's comments regarding
advertising, marketing promotion and sales efforts.

         5.2 SALES AND ADVERTISING ACTIVITIES. Selfcare shall provide ChemTrak
with written copies of all advertising claims which Selfcare intends to make in
connection with HIV Products prior to making any such claim to any third party.
The parties shall mutually agree upon all claims, and either party shall have
the right to prohibit the making of any particular claim for regulatory, ethical
or marketing reasons. Selfcare agrees that no claims prohibited by applicable
law or regulation will be made in connection with HIV Products.

         5.3 PRICING. Selfcare shall notify ChemTrak of the price(s) it intends
to charge third parties for HIV Product at least ninety (90) days prior to
commencing commercial sales in any country. To the extent required under
applicable European Union regulations, Selfcare shall charge the same price for
HIV Product in countries in the Territory that are members of the European
Union. The parties shall discuss optimal pricing strategies and Selfcare shall
consider any comments ChemTrak may have in good faith, provided that Selfcare
shall remain ultimately responsible for determining the price.

         5.4 PACKAGING. Selfcare will be responsible for packaging Sample
Collection Kits for resale under this Agreement, including, without limitation,
designing and producing all packaging materials and product inserts, all in
forms to be approved in writing by ChemTrak prior to first use by Selfcare, such
approval not to be unreasonably withheld. Copyright and other proprietary rights
related to amended packaging, labeling, and inserts shall remain the exclusive
property of Selfcare and may not be used by ChemTrak without the express written
consent of Selfcare; provided, however, that ChemTrak shall own the brand name
under which the product is sold, as provided in Section 2.1(c). Notwithstanding
the foregoing, ChemTrak shall provide Selfcare with copies of all packaging
materials and product inserts which ChemTrak uses in connection with the HIV
Product outside the Territory.

         5.5 GENERAL CONDUCT. Selfcare covenants that it shall not solicit sale
of HIV Products, or advertise or keep a stock of HIV Products, outside of the
Territory. Selfcare shall not, directly or indirectly, without the prior written
authorization of ChemTrak, (i) contact any of ChemTrak's suppliers or vendors of
HIV Product components, or (ii) initiate any contact with any federal, state or
local regulatory agency or entity outside the Territory about the HIV Product.
Selfcare shall conduct its efforts under this Agreement in compliance with all
regulatory requirements applicable to the offer, distribution and sale of HIV
Product. Selfcare shall comply with all health registration laws, regulations
and orders of any government entity within the Territory and with all other
governmental requirements relating to the promotion, marketing and sale of the
HIV Product in the


                                      12.
<PAGE>   17
Territory. The parties agree to cooperate in all respects, including providing
all information and documents in each party's possession, to assure compliance
with adverse event reporting requirements and similar regulations applicable to
the HIV Product, on a worldwide basis, including but not limited post-approval
requirements imposed by the U.S. FDA by PMA approval order or regulation
pursuant to 21 CFR Part 814, Subpart E, and medical device reporting obligations
under 21 CFR Part 803. Each party shall notify the other within 20 days of
becoming aware of any reportable adverse events or device malfunctions
associated with the HIV Products, or sooner to the extent applicable regulatory
requirements require reporting to government officials in a time less than 20
days. In addition, each party will assist the other in investigating any such
reportable events, as reasonably requested, in order to comply with the
applicable regulatory requirements.

                                    ARTICLE 6
                       REPORTS; FORECASTS; MARKETING PLANS

         6.1 REPORTS. Each party shall keep the other fully informed of all
governmental activities and plans which potentially or actually affect the sale
of the HIV Products in the Territory. Selfcare shall provide to ChemTrak from
time to time, but no less than annually, written reports of any known third
party activities relating to the manufacture, sale or distribution of products
that are competitive with HIV Products in the Territory, including all available
information relating to pricing, new products and product promotions. At a
minimum, such reports shall be submitted to ChemTrak by confirmed facsimile
within thirty (30) days after the end of each calendar year.

         6.2 FORECASTS. Beginning thirty (30) days after receipt of the first
Regulatory Approval for HIV Products in the Territory, and on the first day of
each calendar quarter thereafter, Selfcare shall furnish to ChemTrak a
nonbinding rolling twelve (12)-month forecast of its anticipated purchases of
Sample Collection Kits and sales of HIV Products for each country in the
Territory.

         6.3 MARKETING PLANS AND REPORTS. Prior to First Commercial Sale and at
the beginning of each calendar year thereafter, Selfcare shall submit to
ChemTrak in writing whatever annual marketing plan detailing Selfcare's proposed
marketing and pricing strategy and tactics for the HIV Product during the
following year has been developed by Selfcare for its internal use. In addition,
Selfcare shall submit to ChemTrak (a) quarterly sales reports detailing
Selfcare's sales of the HIV Product in the preceding quarter, which reports
shall be submitted to ChemTrak within thirty (30) days after the end of each
quarter; and (b) copies of any market research reports relating to HIV Product
sales and HIV Product competition which Selfcare commissions or otherwise
obtains, which reports shall be submitted to ChemTrak promptly after receipt
thereof by Selfcare.

         6.4 CONFIDENTIAL INFORMATION. All reports, forecasts and plans
generated by or for Selfcare with respect to the HIV Product and provided to
ChemTrak under this Article 6 (collectively, the "Marketing Data") shall
constitute Confidential Information of Selfcare, as defined under Article 8
hereof. Such Marketing Data shall be kept confidential in accordance with
Article 8 but may be used by ChemTrak, only with express written consent from
Selfcare, not to be unreasonably withheld, in connection with the
commercialization of HIV Products.

                                    PAYMENTS

         7.1 EXPENSES. All expenses incurred by Selfcare in connection with its
obligations under this Agreement will be borne solely by Selfcare, subject to
recovery of certain expenses out of Net Sales of HIV Product as provided in
Section 7.4. Selfcare will be responsible for appointing its own employees,
agents and representatives, who will be compensated by Selfcare. ChemTrak shall
only be obliged to incur expenses under Section 3.1 (Regulatory Assistance),
Section 3.3, Article 4 (Supply of Sample Collection Kits) and Article 9
(Intellectual Property), subject to reimbursement of certain expenses by
Selfcare as provided in such sections.
   

         7.2 LICENSE FEE. Selfcare shall pay to ChemTrak a license fee of

non-refundable and shall not be creditable against any future payments due to
ChemTrak.
    

         7.3 SALES MILESTONE PAYMENTS. In addition to the Royalty payments
provided for in Section 7.4, Selfcare shall, upon the achievement of the events
set forth below, make the following payments to ChemTrak:

   
                  (a) XXXXXXXX upon obtaining Regulatory Approval in the first
of the U.K., Germany or France; and

                  (b) XXXXXXXX upon achieving the first XXXXXXXXXX in Net Sales
from the sale of HIV Products in the Territory.
    

         Payments made pursuant to this Section 7.3 shall be non-refundable and
shall not be creditable against any future payments.

   
         7.4 ROYALTIES. Within thirty (30) days after the end of each calendar
quarter, Selfcare shall deliver a report to ChemTrak detailing Selfcare's Net
Sales made in such quarter and all other compensation invoiced, earned or
received in respect of the offer, sale or distribution of HIV Products in such
quarter, and XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX 
XXXXXXXXXXXXXXXXXXXXXXXXXX, with line items for each of the deductions

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX. For purposes of calculating
quarterly Royalty payments, all receipts and deductions included in Net Sales
shall be recognized as of the date of invoice and XXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX.
Together with Selfcare's report due 30 days after the end of each quarter,
Selfcare shall pay the Royalty for such quarter to ChemTrak. If

the next quarter and set off against future Royalty payments.
    

         7.5 MANNER AND PLACE OF PAYMENT. Any payments to ChemTrak shall be made
in U.S. Dollars by wire transfer at such bank in the United States as ChemTrak
shall specify from time to time. Payments shall be made for the amount of U.S.
Dollars reported by ChemTrak (in the case of expense reimbursement) or agreed by
the Parties (in the case of a Purchase Price). Exchange conversion of foreign
currencies will be the responsibility of Selfcare; provided that for purposes of
calculating U.S. Dollar payments to be made by Selfcare to ChemTrak hereunder
all revenues received and costs paid in foreign currencies shall be deemed
converted to U.S. Dollars at the exchange rate for each currency that is the
average of the daily spot rate reported by the U.S. edition of the Wall Street
Journal for each trading day during the reporting period.

         7.6 RECORDS AND AUDIT OF SALES AND EXPENSES. Each Party will maintain
complete and accurate records regarding sales, costs, expenses and payments
applicable to HIV Products, in sufficient detail to enable the other Party to
confirm the accuracy of payments due under this Agreement. In particular,
Selfcare shall keep separate records of each of the categories of costs
specifically referenced in the definition of Commercialization Costs. Such
records shall be open, during reasonable business hours for a period of three
(3) years from creation of the record, for examination at the other Party's
expense and not more often than once each year by a certified public accountant
from a major recognized accounting firm selected by the other Party for the sole
purpose of verifying the correctness of calculations made under this Agreement.
The accounting expense shall be paid by the Party requesting the audit. If
material discrepancies (in excess of 5%) are identified in such audit, the
audited Party shall bear the accounting expense. Any records or accounting
information received from the other Party shall be Confidential Information. The
terms of this section shall survive any termination or expiration of this
Agreement for a period of three (3) years.

                                 CONFIDENTIALITY

         8.1 NONDISCLOSURE OBLIGATIONS. During the term of this Agreement, and
for a period of three (3) years after termination hereof, each Party will
maintain all Confidential Information in trust and confidence and will not
disclose any Confidential Information to any third party or use any Confidential
Information for any unauthorized purpose. Each Party may use such Confidential
Information only to the extent required to accomplish the purposes of this
Agreement. Confidential Information shall not be used for any purpose or in any
manner that would constitute a violation of any laws or regulations, including
without limitation the export control laws of the United States. Confidential
Information shall not be reproduced in any form except as required to accomplish
the intent of this Agreement. No Confidential Information shall be disclosed to
any employee, agent, consultant, sublicensee or supplier who does not have a
need for such information. To the extent that disclosure is authorized by this
Agreement, the disclosing Party will obtain prior agreement from its employees,
agents, consultants, sublicensees or suppliers to whom disclosure is to be made
to hold in confidence and not make use of such information for any purpose other
than those permitted by this Agreement. Each Party will promptly notify the
other upon discovery of any unauthorized use or disclosure of the Confidential
Information.

         8.2 EXCEPTIONS. Confidential Information shall not include any
information which:

                  (a) is now, or hereafter becomes, through no act or failure to
act on the part of the receiving Party, generally known or available;

                  (b) is known by the receiving Party at the time of receiving
such information, as evidenced by its written records;

                  (c) is hereafter furnished to the receiving Party by a third
party, as a matter of right and without restriction on disclosure; or

                  (d) is the subject of a written permission to disclose
provided by the disclosing Party.

         8.3 AUTHORIZED DISCLOSURE. Notwithstanding any other provision of this
Agreement, each Party may disclose Confidential Information if such disclosure:

                  (a) is in response to a valid order of a court or other
governmental body of the United States or any political subdivision thereof;
provided, however, that the responding Party shall first have given notice to
the other Party hereto and shall have




                                       16.
<PAGE>   21
made a reasonable effort to obtain a protective order requiring that the
Confidential Information so disclosed be used only for the purposes for which
the order was issued;

                  (b) is otherwise required by law, provided that the Disclosing
Party take all available steps to designate the information as confidential and
to prevent further disclosure by the recipient; or

                  (c) is otherwise necessary to file or prosecute patent
applications, prosecute or defend litigation or comply with applicable
governmental regulations or otherwise establish rights or enforce obligations
under this Agreement, but only to the extent that any such disclosure is
necessary, provided that the Disclosing Party take all available steps to
designate the information as confidential and to prevent further disclosure by
the recipient.

         8.4 TERMS OF THIS AGREEMENT. The Parties agree that the material
financial terms of this Agreement will be considered Confidential Information of
both Parties. However, each Party shall have the right to disclose the material
financial terms of this Agreement to any potential acquirer, merger partner, or
other bona fide potential financial or strategic partner, subject to a
requirement of best efforts to secure confidential treatment of such
information.

                                    ARTICLE 9
                              INTELLECTUAL PROPERTY

         9.1 OWNERSHIP OF INTELLECTUAL PROPERTY. ChemTrak shall retain all of
its rights, title and interest in and to all ChemTrak Technology, including but
not limited to the Software, and all modifications and improvements to the
foregoing. ChemTrak shall also own all right, title and interest in all
copyrights, trademarks, including but not limited to the Aware(TM) trademark,
and trade names and all other industrial and intellectual property embodied in
or related to the HIV Product, except as otherwise expressly provided in this
Agreement. ChemTrak shall file for and pursue trademark protection for the
Aware(TM) mark in countries in the Territory where HIV Products are sold, at
Selfcare's expense, subject to recovery as a Commercialization Cost. ChemTrak
shall also file for and pursue patent protection for the finger stick device in
countries in the Territory where the Parties agree patent protection would be
advantageous. Selfcare shall bear the initial costs of obtaining and maintaining
such patent prosecution, and such costs shall be Commercialization Costs.

         9.2 DEFENSE OF INTELLECTUAL PROPERTY SUITS. If a third party asserts
that a patent, trademark or other proprietary right owned by it is infringed or
otherwise violated by the offer, distribution or sale of the HIV Product in the
Territory, the Party against whom such a claim was asserted shall immediately
provide the other Party notice of such



                                       17.
<PAGE>   22
   
                             Confidential Treatment
    

claim and the related facts in reasonable detail. ChemTrak shall have the first
right, but not the obligation, to act to resolve the issue through negotiation
and to control the defense of any legal proceeding. If ChemTrak assumes the
defense, Selfcare shall cooperate with ChemTrak and shall have the right to be
represented separately by counsel of its own choice. If ChemTrak fails to notify
Selfcare, within thirty (30) days after receiving notice that a complaint has
been filed with a court of competent jurisdiction (but in any event reasonably
in advance of any deadline for responding to the complaint), that ChemTrak will
assume control of the defense, then Selfcare shall have the right, but not the
obligation, to so control the defense by counsel of its own choice. If Selfcare
assumes the defense, ChemTrak shall cooperate with Selfcare and shall have the
right to be represented separately by counsel of its own choice.

   
         9.3 EXPENSES AND REMEDIES. ChemTrak shall bear XXXX XXXXXXX expenses
incurred by ChemTrak or Selfcare in the defense of suits described in Section
9.2, including but not limited to attorneys' fees and expenses. If Selfcare
assumes the defense pursuant to Section 9.2, Selfcare shall not enter into any
settlement that may adversely affect the HIV Product outside the Territory, or
require ChemTrak to make any payment to a third party or Selfcare, without the
prior written consent of ChemTrak. If ChemTrak assumes the defense, ChemTrak may
settle any such suit at any time in any manner that does not materially
adversely affect Selfcare. ChemTrak shall notify Selfcare in writing in the
event it proposes to resolve the matter in any other manner, and the Parties
shall discuss available options in good faith and each shall use all
commercially reasonable efforts to reach a mutually agreed upon resolution
within forty five (45) days after the date of ChemTrak's notice. Such actions
may include (i) procuring the right from such third party to sell or use the HIV
Product, with any running royalty obligations to be subject to approval by both
Parties (not to be unreasonably withheld) and, if approved, to be included in
Commercialization Costs, (ii) replacing the HIV Product with a functionally
equivalent product that does not violate the third party's rights, or (iii)
modifying the HIV Product to make it functionally equivalent and not violate
such rights. If the Parties are unable to reach agreement on how to resolve such
matter after the above discussion period, and either Party reasonably determines
that continued sale of the HIV Product in the Territory would infringe or
violate the third party's rights, then such Party may cease performance under
this Agreement immediately upon written notice to the other Party and this
Agreement shall terminate thirty (30) days after the date of such notice.
    

         9.4 DISCLAIMER. THE FOREGOING PROVISIONS OF THIS ARTICLE 9 STATE THE
ENTIRE LIABILITY AND EXCLUSIVE REMEDY OF THE PARTIES AND THEIR CUSTOMERS WITH
RESPECT TO ANY ALLEGED INFRINGEMENT OF PATENTS, COPYRIGHTS, TRADEMARKS OR OTHER
INTELLECTUAL PROPERTY RIGHTS BY THE HIV PRODUCTS OR ANY PART THEREOF.

         9.5 PROSECUTION OF INTELLECTUAL PROPERTY SUITS. If either party
believes that a third Party is infringing any patent, copyright, trademark or
other intellectual property right belonging to the parties and applicable to the
HIV Product in the Territory, it shall promptly notify the other Party. The
Parties shall meet and discuss whether to take action to abate the infringement
and, if so, what actions to take, which Party will take such actions and how
related expenses will be borne between the Parties. If either Party elects to
initiate such a suit, the other Party shall cooperate in the action and have the
right but not the obligation to bear up to one-half the expenses of the suit,
provided that such Party undertakes in writing within ninety (90) days after the
suit is initiated to bear a stated percentage of such costs. Any recovery or
settlement obtained in such an action shall be used first to reimburse each
Party pro rata for litigation expenses. Any remaining recovery will be allocated
between the parties in proportion to the share of litigation expenses they bore.

                     TERM AND TERMINATION; CHANGE OF CONTROL

   
         10.1 TERM. This Agreement shall become effective on the Effective Date
and shall remain in effect for a period of five (5) years from the date of
Selfcare's first commercial sale of HIV Product in any country listed on Exhibit
C (the "Fifth Anniversary"), unless it is renewed by agreement of the parties or
automatically as provided below. The Agreement will automatically renew for a
period of two (2) years if, as of the date sixty (60) days prior to the Fifth
Anniversary, Selfcare's market share for the HIV Product throughout the five (5)
countries listed on Exhibit C, in the aggregate, is at least equal to XXXXX
XXXXXXX XXXXX, determined by dividing Selfcare's net sales (as reported for
financial purposes) of HIV Products in such countries over the previous twelve
(12) month period by the total net sales (as reported for financial purposes) of
all sellers of mail-in HIV blood tests in such countries. The same test will be
applied as of the date sixty (60) days before the two-year renewal term expires.
If the test is met, the Agreement will renew for subsequent two-year terms in
the same manner.
    

         10.2 CHANGE OF CONTROL.

                  (a) If Selfcare undergoes an Acquisition Transaction (as
defined below), ChemTrak shall have the right to terminate this Agreement upon
six (6) months prior written notice to Selfcare.

                  (b) If ChemTrak undergoes an Acquisition Transaction, ChemTrak
(or the surviving entity in the Acquisition Transaction) shall have the right to
assume from Selfcare all rights licensed to Selfcare under this Agreement, as
follows. If ChemTrak elects to assume such role, it shall so notify Selfcare in
writing within six (6) months of the closing of ChemTrak's Acquisition
Transaction. Promptly following delivery of such

                                       19.
<PAGE>   24
notice, the parties shall meet to mutually select a recognized investment
banking firm with substantial relevant industry expertise to (i) select three
(3) reasonable methods of determining the value of this Agreement to Selfcare as
of the date of ChemTrak's election notice to Selfcare and (ii) to calculate such
valuation using each of the three (3) methods and provide a report to each
Party. For the purposes of this valuation, Selfcare is deemed to have met the
requirements for maintaining an exclusive license in each country in the
Territory, without regard to whether Selfcare has actually sought Regulatory
Approval or marketed a product in each country in the Territory. ChemTrak shall
have the option to terminate this Agreement and obtain all licenses, rights,
information, materials, contract rights and assistance from Selfcare as may be
necessary or useful to enable ChemTrak to take over Selfcare's position of
exclusive distributor and seller of HIV Products in the Territory (to "Assume
the Business"), at the average of the three (3) valuations calculated by the
investment banker. If ChemTrak is interested in exercising such option, it shall
so notify Selfcare within thirty (30) days of receiving the three valuation
figures from the investment banker. Promptly following delivery of such a
notice, the parties shall negotiate in good faith the details of a transaction
for ChemTrak to assume the business at such a valuation. If the parties are
unable or unwilling to close such a transaction within ninety (90) days of
ChemTrak's notice, then ChemTrak may submit the matter to binding mediation to
resolve the terms of such transaction.

                  (c) An "ACQUISITION TRANSACTION" shall mean a merger or
consolidation of a Party with or into any other entity, including a reverse
triangular merger involving such Party, a sale of all or substantially all of
the assets or business of such Party, or a similar transaction, or a sale of the
business unit to which this Agreement relates, whereby the controlling
shareholders of a Party before the transaction own less than 50% of the shares
of the Party after the transaction.

         10.3 TERMINATION FOR MATERIAL BREACH. If either Party is in material
breach of this Agreement, the non-breaching Party may give written notice to the
breaching Party of its intention to terminate this Agreement, and this Agreement
shall terminate sixty (60) days after the giving of such notice unless during
the 60-day period the breach has been cured. If the allegedly breaching Party
files a court action or initiates an arbitration proceeding denying the breach,
then both Parties shall continue to perform this Agreement pending resolution of
such action.

period not to exceed ninety (90) days, to sell any HIV Products remaining in

not subject to any setoff or similar right) or (ii) any confidentiality
obligation under Article 8 hereof. The due date of all outstanding invoices to
Selfcare for HIV Products shall automatically be accelerated to become due and
payable by immediate wire transfer on the effective date of termination, even if
longer terms have been previously agreed to. ChemTrak may, at its sole option,

effective date of termination and (ii) repurchase Selfcare's remaining inventory
of HIV Products in accordance with Section 10.4(c) below.

but not the obligation, to repurchase from Selfcare all of the HIV Product (to
the extent that the same are in new and original condition) then in Selfcare's
inventory, F.O.B. Selfcare's facilities, whereupon ChemTrak shall repay to
Selfcare the actual price paid by Selfcare to ChemTrak for such returned HIV
Products less any and all amounts owing and uncontested, for whatever reason,
from Selfcare to ChemTrak.

                  (d) CONFIDENTIAL INFORMATION. Each party shall return to the
other or destroy, at the other party's instruction, all Confidential Information
of the other party, with the exception of records required to be maintained to

ChemTrak, ChemTrak shall have the right to retain copies of, and use for its own
internal marketing purposes, any Marketing Data (as defined under Section 6.3),
provided Selfcare has given prior written consent.

          (c) Sellers and Buyers shall indemnify the other for all Taxes for the
periods and in the manner described in Section 6.5 which shall be the sole and
exclusive basis of indemnity for Taxes under this Agreement.

     8.2  PROCEDURES.

          (i) Promptly after the receipt by any Person entitled to indemnity
     hereunder of notice under this paragraph 8.2, of (a) any claim or (b) the
     commencement of any action or proceeding, such Person (the "Aggrieved
     Party") will, if a claim with respect thereto is to be made against any
     party obligated to provide indemnification pursuant to this Article 8 (the
     "Indemnifying Party"), give such Indemnifying Party written notice of such
     claim or the commencement of such action or proceeding and shall permit the
     Indemnifying Party to assume the defense of any such claim or any
     litigation resulting from such claim, and, upon such assumption, shall
     cooperate fully with the Indemnifying Party in the conduct of such defense.
     Failure by the Indemnifying Party to notify the Aggrieved Party of its
     election to defend any such action within a reasonable time, but in no
     event more than fifteen days after notice thereof shall have been given to
     the Indemnifying Party, shall be deemed a waiver by the Indemnifying Party
     of its right to defend such action. If the Indemnifying Party assumes the
     defense of any such claim or litigation resulting therefrom, the
     obligations of the Indemnifying Party as to such claim shall be limited to
     taking all steps reasonably necessary in the defense or settlement of such
     claim or litigation resulting therefrom. The Aggrieved Party may
     participate, at its expense, in the defense of such claim or litigation
     provided that the Indemnifying Party shall direct and control the defense
     of such claim or litigation. The Indemnifying Party shall not, in the
     defense of such claim or any litigation resulting therefrom, consent to
     entry of any judgment, except with the written consent of the Aggrieved
     Party, or enter into any settlement, except with the written consent of the
     Aggrieved Party, which does not include as an unconditional term thereof
     the giving by the claimant or the plaintiff to the Aggrieved Party of a
     release from all liability in respect of such claim or litigation. In
     addition, all awards and costs payable by a third party to the Aggrieved
     Party or the Indemnifying Party previously paid by an Indemnifying Party
     shall belong to the Indemnifying Party.

          (ii) If the Indemnifying Party shall not assume the defense of any
     such claim or litigation resulting therefrom, the Aggrieved Party may
     defend against such claim or litigation in such manner as it may deem
     appropriate and, unless the Indemnifying Party shall deposit with the


                                      -27-
<PAGE>   28



     Aggrieved Party a sum equivalent to the total amount demanded (subject to
     the limitation set forth in Section 8.3(b)) in such claim or litigation
     less the Minimum Loss, or shall deliver to the Aggrieved Party a surety
     bond in form and substance reasonably satisfactory to the Aggrieved Party
     in such amount, the Aggrieved Party may settle such claim or litigation on
     such terms as it may deem appropriate, and the Indemnifying Party shall
     promptly reimburse the Aggrieved Party for the amount of all expenses,
     legal or otherwise, incurred by the Aggrieved Party in connection with the
     defense against or settlement of such claim or litigation. If no settlement
     of such claim or litigation is made, the Indemnifying Party shall promptly
     reimburse the Aggrieved Party for the amount of any judgment rendered with
     respect to such claim or in such litigation and of all expenses, legal or
     otherwise, incurred by the Aggrieved Party in the defense against such
     claim or litigation subject to the limitations set forth in Article 8.

     8.3  LIMITATIONS. (a) An Aggrieved Party shall not be entitled to recover
any Costs under Section 8.1(a)(i), (ii) and (iv) until the aggregate amount of
the Costs suffered by the Aggrieved Party thereunder shall exceed $350,000.00
(the "Minimum Loss"), at which time the indemnification provided under Section
8.1(a)(i), (ii) and (iv) shall apply to all Costs in excess of the Minimum Loss,
and (b) the maximum liability under Section 8.1(a)(i), (ii) and (iv) or
8.1(b)(i) and (ii), as the case may be, for an Indemnifying Party shall not
exceed $18,000,000.00 in the aggregate. Solely for purposes of Article 8, if a
breach of representation or warranty has occurred in accordance with its terms
(including giving effect to any materiality qualifications), in determining the
amount of Costs resulting therefrom, such representation or warranty shall be
read and interpreted as if any materiality qualifications were not contained
therein.

     8.4  INDEMNIFICATION AS SOLE REMEDY. To the fullest extent permitted by 
law, the indemnification provided in this Article 8, subject to the limitations
set forth herein, shall be the exclusive post-Closing remedy for damages
available to any Aggrieved Party.


                                    ARTICLE 9

                        TERMINATION, AMENDMENT AND WAIVER

<PAGE>   29


          (b) by Buyers or Sellers if the Closing shall not have occurred on or
prior to February 28, 1997, PROVIDED, HOWEVER, that a party shall not have the
right to terminate under this Section 9.1(b) if such party's (or such party's
Affiliates) failure to fulfill any obligation under this Agreement has been the
cause of, or resulted in the failure of the Closing to occur on or before such
date;

          (c) subject to Section 6.3, by Buyers or Sellers if a court of 
competent jurisdiction or Governmental Authority shall have issued an order,
decree or ruling or taken any other action, in each case permanently
restraining, enjoining or otherwise prohibiting the transactions contemplated by
this Agreement, and such order, decree, ruling or other action shall have become
final and nonappealable; or

          (d) by Sellers at any time after February 6, 1997 if Sellers have not
received a copy of the Commitment Letter satisfactory to Sellers in their
reasonable judgement.

          The date on which this Agreement is terminated pursuant to any of the
foregoing subsections of this Section 9.1 is herein referred to as the
"Termination Date."

     9.2  EFFECT OF TERMINATION. Except as set forth in Section 5.2, upon the
termination of this Agreement pursuant to Section 9.1, this Agreement shall
forthwith become null and void, except that nothing herein shall relieve any
party from liability for breach of this Agreement prior to such termination and
the provisions of Articles 8 and 10 shall survive such termination with respect
to any such breach.


                                   ARTICLE 10

obligations of the parties shall be construed and enforced accordingly.

agree that Buyers may sell and distribute the Product using Sellers' labeling 
and/or packaging.

13.  FORCE MAJEURE.
     -------------

          Neither party shall be liable for failure to perform any of its

this Paragraph 14 hereof shall not affect the rights of the terminating party
under this Agreement or under applicable laws.

[Selfcare Letterhead]


                                November 25, 1996


Certain holders of 10% Promissory
Notes (the "Notes") of Selfcare, Inc.
dated March 30, 1995


Dear Noteholder:

     Pursuant to the letter agreement dated July 19, 1996 (the "AMEX Letter
Agreement") by and between you and Selfcare, Inc. (the "Company"), you and
certain other holders (the "Certain Holders") waived repayment of any principal
amount of any Notes held by you and the Notes of the Certain Holders until such
date (the "Determination Date") as Selfcare's stockholders' equity as of
November 30, 1996 (the "Measurement Date") has been determined (but no later
than December 31, 1996). You and the Certain Holders further agreed that if the
Company's stockholders' equity as of the Measurement Date was determined on the
Determination Date to be less than $4.0 million, the principal amount of your
and their Notes, together with any accrued but unpaid interest thereon through
the Determination Date, would be automatically converted as of the Determination
Date into a number of shares of common stock, par value $.001 per share (the
"Common Stock"), of the Company. Your agreement helped the Company obtain
approval from the American Stock Exchange to list the Company's Common Stock on
the exchange and complete its successful initial public offering on August 6,
1996.

     As a result of recent developments, the Company believes its stockholders'
equity as of the Measurement Date will substantially exceed $4.0 million.
Accordingly, under the terms of the AMEX Letter Agreement, the Company believes
it will be obligated to repay the principal amount of your Notes and the Notes
of the Certain Holders in full, together with any accrued but unpaid interest,
on a date (the "Payment Date") which is within five (5) business days after the
Determination Date.

     The Company, however, would prefer to delay repayment of the principal of
your Notes and the Notes held by the Certain Holders until January 15, 1998.
Accordingly, the Company is hereby asking you and the Certain Holders to agree
to the following:

     1. You and the Company hereby agree that, notwithstanding anything in the
Notes to the contrary, the principal amount of your Notes is to be repaid in
full, within five (5) business days after January 15, 1998 (the "New Repayment
Date"). On the New Repayment 
<PAGE>   2

Date you also will receive an amount equal to the accrued but unpaid interest
from January 1, 1998 through the New Repayment Date.

     2. The Company hereby agrees that, notwithstanding your agreements herein,
you will remain entitled to (a) exercise any warrants to purchase shares of the
Company's Common Stock you already hold which were issued in connection with the
Notes as if the principal amount of your Notes, were repaid in full on the
Payment Date (in other words, you will be entitled to exercise such warrants for
the number of shares currently covered thereby during the thirty (30) day period
following the Payment Date); and (b) continue to receive payments for interest
on the principal amount of your Notes on the first business day of each calendar
quarter for the immediately preceding quarter.

     3. In consideration for your agreement to the terms of this letter, the
Company will issue to you after December 3, 1996 additional warrants, dated
December 3, 1996 (the "Additional Warrants"), to purchase shares of the
Company's Common Stock in substantially the form attached hereto as EXHIBIT A.
The number of Additional Warrants that you will receive by accepting this letter
agreement will equal your Proportionate Share (as hereinafter defined) of
warrants to purchase an aggregate of 50,000 shares of the Company's Common
Stock. The term "Proportionate Share" shall mean that portion of warrants to
purchase an aggregate of 50,000 shares of the Company's Common Stock multiplied
by a fraction, the numerator of which is the principal amount of your Notes and
the denominator of which is $2.75 million. The initial exercise price per share
of Common Stock underlying the Additional Warrants shall equal the average
closing price of the Company's Common Stock on the American Stock Exchange on
November 26, 27 and 29, 1996 (the "Exercise Price").

     4. As further consideration for your agreement to the terms of this letter
agreement, if your Notes are outstanding as of June 30, 1997 and the Company has
not sold shares of Common Stock after the date hereof and on or before June 30,
1997 pursuant to a registration statement on Form SB-2 (or a similar form), then
the Company will issue to you by July 15, 1997, additional warrants, dated June
30, 1997 (the "Secondary Warrants"), to purchase shares of the Company's Common
Stock in substantially the form attached hereto as EXHIBIT A. The number of
Secondary Warrants that you will receive will equal your Proportionate Share of
warrants to purchase an aggregate of 25,000 shares of the Company's Common
Stock. The initial exercise price per share of Common Stock underlying the
Secondary Warrants shall equal the Exercise Price. The aggregate number of
shares of 25,000 and the Exercise Price will be appropriately adjusted to
reflect any adjustments which would have been made if the Secondary Warrants had
instead been issued on December 3, 1996.

     5. You hereby agree that you will not transfer or assign any rights
contained herein without the prior written consent of the Company. You also
hereby acknowledge and agree that the contents of this letter agreement shall
remain confidential and that neither you nor any of your employees, agents or
advisors will disclose any information contained herein in any manner
whatsoever.

     Enclosed for your information is a copy of the Company's quarterly report
on Form 10-QSB dated November 14, 1996 (without exhibits). Although you should
make your decision based on what you believe is best for you, I should tell you
that every director of the

<PAGE>   3

Company who holds Notes has personally agreed to the terms of this letter
agreement including Bill Umphrey, Carol Goldberg, John Levy and my family. If 
you wish to accept this offer, please (i) execute this letter by signing on the

[Selfcare Letterhead]

                                December 31, 1996


All holders of 10% Promissory
Notes (the "Notes") of Selfcare, Inc.
dated March 30, 1995


Dear Noteholder:

     Selfcare, Inc. (the "Company") has agreed with holders of the Notes to
revise the terms of the Notes, issue new warrants to the holders of the Notes,
and replace the existing warrants with an agreement to issue the shares covered
thereby by January 15, 2000 at the latest. As a result of these changes, the
holders of the existing warrants will be able to postpone until such issuance
the recognition of a significant amount of taxable income which otherwise might
have to be reported on their 1996 tax returns.

     More specifically, the terms of the agreement are as follows:

     1. You and the Company hereby agree that, notwithstanding anything in the
Notes or elsewhere to the contrary, the principal amount of your Notes is to be
repaid in full within five (5) business days after January 15, 1998 (the "New
Repayment Date"). You will continue to be entitled to continue to receive
payments of interest on the principal amount of your Notes on the first business
day of each calendar quarter for the immediately preceding quarter. On the New
Repayment Date you also will receive an amount equal to the accrued but unpaid
interest from January 1, 1998 through the New Repayment Date.

     2. You and the Company hereby agree that each warrant to purchase shares of
the Company's common stock, par value $.00l per share (the "Common Stock"),
which was issued to you in connection with the issuance of the Notes is hereby
terminated and canceled as of the date hereof. In exchange therefor, the Company
agrees that it will transfer to you, for no additional consideration, the number
of shares to which your warrant currently applies (i.e., your proportionate part
of the 1,142,635 shares of Common Stock for which all such warrants could be
exercised if they all were exercisable today) on the earlier of (i) January 15,
2000 or (ii) the date on which a Change in Control (as defined in Section 6)
occurs. The Company will pay any transfer taxes due with respect to such
transfer and will appropriately adjust the number of shares to be transferred in
the event a stock dividend, stock split or 



<PAGE>   2

reverse stock split with respect to the Common Stock occurs between the date
hereof and the transfer of such shares.

     3. In consideration for your agreement to the terms of this letter, the
Company will issue to you new warrants (the "New Warrants") to purchase shares
of the Company's Common Stock in substantially the form attached hereto as
EXHIBIT A. The number of New Warrants that you will receive by accepting this
letter agreement will equal your Proportionate Share (as hereinafter defined) of
warrants to purchase an aggregate of 54,545 shares of the Company's Common
Stock. The term "Proportionate Share" shall mean that portion of warrants to
purchase an aggregate of 54,545 shares of the Company's Common Stock multiplied
by a fraction, the numerator of which is the principal amount of your Notes and
the denominator of which is $3 million. The initial exercise price per share of
Common Stock in the New Warrants will be $12.875 (the "Exercise Price").

     4. As further consideration for your agreement to the terms of this letter
agreement, if your Notes are outstanding as of June 30, 1997 and the Company has
not sold shares of Common Stock after the date hereof and on or before June 30,
1997 pursuant to a registration statement on Form SB-2 (or a similar form), then
the Company will issue to you by July 15, 1997, additional warrants, dated June
30, 1997 (the "Secondary Warrants"), to purchase shares of the Company's Common
Stock in substantially the form attached hereto as EXHIBIT A. The number of
Secondary Warrants that you will receive will equal your Proportionate Share of
warrants to purchase an aggregate of 27,273 shares of the Company's Common
Stock. The initial exercise price per share of Common Stock underlying the
Secondary Warrants shall equal the Exercise Price. The aggregate number of
shares of 27,273 and the Exercise Price will be appropriately adjusted to
reflect any adjustments which would have been made if the Secondary Warrants had
instead been issued on December 31, 1996.

     5. You hereby agree that you will not transfer or assign any rights
contained herein without the prior written consent of the Company. You also
hereby acknowledge and agree that neither you nor any of your employees, agents
or advisors will disclose any information contained herein in any manner
whatsoever.

     6. For purposes of this Agreement, a "Change in Control" shall mean the
occurrence of any one of the following events:

          (i) any "person," as such term is used in Sections 13(d) and 14(d) of
     the Securities Exchange Act of 1934, as amended (the "Act"), (other than
     the Company, any of its subsidiaries, or any trustee, fiduciary or other
     person or entity holding securities under any employee benefit plan or
     trust of the Company or any of its subsidiaries), together with all
     "affiliates" and "associates" (as such terms are defined in Rule 12b-2
     under the Act) of such person, shall become the "beneficial owner" (as such
     term is defined in Rule 13d-3 under the Act), directly or indirectly, of
     securities of the Company representing in excess of 50% of either (A) the
     combined voting power of the Company's then outstanding securities having
     the right to vote in an


<PAGE>   3



     election of the Company's Board of Directors ("Voting Securities") or (B)
     the then outstanding shares of Common Stock of the Company (in either such
     case other than as a result of an acquisition of securities directly from
     the Company); or

          (ii) persons who, as of December 31, 1996, constitute the Company's
     Board of Directors (the "Incumbent Directors") cease for any reason,
     including, without limitation, as a result of a tender offer, proxy
     contest, merger or similar transaction, to constitute at least a majority
     of the Board, provided that any person becoming a director of the Company
     subsequent to such date whose election or nomination for election was
     approved by a vote of at least a majority of the Incumbent Directors shall,
     for purposes of this Agreement, be considered an Incumbent Director; or

          (iii) the stockholders of the Company shall approve (A) any
     consolidation or merger of the Company or any subsidiary thereof where the
     shareholders of the Company, immediately prior to the consolidation or
     merger, would not, immediately after the consolidation or merger,
     beneficially own (as such term is defined in Rule 13d-3 under the Act),
     directly or indirectly, shares representing in the aggregate 80% or more of
     the voting shares of the corporation issuing cash or securities in the
     consolidation or merger (or of its ultimate parent corporation, if any),
     (B) any sale, lease, exchange or other transfer (in one transaction or a
     series of transactions contemplated or arranged by any party as a single
     plan) of all or substantially all of the assets of the Company or (C) any
     plan or proposal for the liquidation or dissolution of the Company.

     Notwithstanding the foregoing, a "Change in Control" shall not be deemed to
have occurred for purposes of the foregoing clause (i) solely as the result of
an acquisition of securities by the Company which, by reducing the number of
shares of Common Stock or other Voting Securities outstanding, increases (x) the
proportionate number of shares of Common Stock beneficially owned by any person
in excess of 50% or more of the shares of Common Stock then outstanding or (y)
the proportionate voting power represented by the Voting Securities beneficially
owned by any person in excess of 50% or more of the combined voting power of all
then outstanding Voting Securities; PROVIDED, HOWEVER, that if any person
referred to in clause (x) or (y) of this sentence shall thereafter become the
beneficial owner of any additional shares of Common Stock or other Voting
Securities (other than pursuant to a stock split, stock dividend, or similar
transaction) and then beneficially owns in excess of either 50% of the Common
Stock then outstanding or of 50% or more of such combined voting power, then a
"Change in Control" shall be deemed to have occurred for purposes of the
foregoing clause (i).

     7. This Agreement supersedes and replaces all other agreements with respect
to the exchange or conversion of your Note or any change in the date of payment
thereof.

                          SALES DISTRIBUTION AGREEMENT
                          ----------------------------

                            FOR A TESTING SYSTEM FOR

                                  BLOOD GLUCOSE

     This Distribution Agreement is made as of October 9, 1996 by and between
Selfcare, Inc., a Delaware corporation ("Selfcare"), and LifeScan, Inc., a
California corporation ("LifeScan"). This Distribution Agreement is entered into
pursuant to the Master Agreement dated as of November 10, 1995 (the "Master
Agreement") by and among Selfcare, LifeScan and Johnson & Johnson Development
Corporation, a New Jersey corporation and relates to a home-use testing system
for measuring the concentration of blood glucose.

     In consideration of the mutual covenants contained herein, and in
accordance with the terms of the Master Agreement, and for other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties agree as follows:

                                    ARTICLE I
                   DEFINITIONS AND REVISIONS TO GLUCOSE SYSTEM

     1.1 REVISIONS TO GLUCOSE SYSTEM. LifeScan and Selfcare intend to
commercialize a different home use testing system for measuring the
concentration of blood glucose than that described in Schedule 1.1 to the Master
Agreement and hereby agree that for purposes of this Agreement, "Glucose System"
means the electrochemical blood glucose testing system described in Schedule 1.1
to this Agreement, as the same may be modified with the written approval of
LifeScan or pursuant to Section 3.5 of the Master Agreement. The parties note
that payments made and required to be made by LifeScan under the Master
Agreement and the payment for surrender and conversion of the Convertible
Promissory Notes by Johnson & Johnson Development Corporation pursuant to the
Investment Agreement continue to be governed by the definition of Glucose System
set forth in those Agreements. The parties do not intend to duplicate the
requirement of such payments and such payment, surrender and conversion based on
the definition of Glucose System set forth in the Master Agreement and the
Investment Agreement. Selfcare shall prepare a draft 510(k) Notification with
respect to the Glucose System and Section 3.5 of the Master Agreement will apply
to it such 510(k) Notification. Selfcare and LifeScan anticipate agreeing in the
future to make changes from time to time in the specification for the Glucose
System. LS Product produced by Selfcare for LifeScan which deviates from the
required specification in minor respects or which does not yet comply with
agreed changes shall be deemed to comply with the requirements of this Agreement
so long as such LS Product meets applicable regulatory requirements and is
accepted for purchase by LifeScan. In such a case the provisions of Article VII
shall not apply based solely on any such minor deviations.

                                   ARTICLE II
                              SUPPLY OF LS PRODUCTS

     2.1 SUPPLY OF LS PRODUCTS. Selfcare and LifeScan agree that, after Selfcare
has given notice to LifeScan that it is prepared to commence commercial
production of LS Products and thereafter during the term of this Distribution
Agreement, LifeScan shall have the right to purchase from Selfcare on the terms
and conditions set forth herein and resell the following products (collectively,
"LS Products"): (i) Instruments ("LS Instruments"), (ii) Test Strips ("LS
Strips") designed to be used with LS Instruments, and (iii) Related Components,
which in each case meet the specifications for the Glucose System. LS Products
shall be manufactured by or at the direction of Selfcare for purchase and resale
by LifeScan under this Distribution Agreement. LS Products shall not be resold
by LifeScan except (i) under a brand name and trade dress that is proprietary to
LifeScan or an Affiliate or (ii) on a private label basis under a brand name and
trade dress that is proprietary to any Person which is not an LS Established
Person.

     "LS Established Person" means any Person which had, prior to its first
purchase from LifeScan of LS Products or other blood glucose measurement
devices, more than $100,000,000 in annual worldwide sales in the market for home
use testing of blood glucose.

     2.2 SUPPLY EXCLUSIVITY. Except as permitted by Article VII, during the term
of this Distribution Agreement, neither LifeScan nor any Affiliate of LifeScan
shall purchase from any supplier other than Selfcare any Compatible Product.
"Compatible Product" means any Instrument, Test Strip or Related Component which
is designed to be used with LS Instruments or LS Strips.

     2.3 SAFETY STOCK. Commencing one (1) year after the first date as of which
LifeScan requests delivery of LS Products, Selfcare will exercise reasonable
efforts to maintain an inventory of LS Products available to deliver to LifeScan
sufficient to satisfy the greater of (i) two (2) times the average monthly
purchases by LifeScan over the past six (6) months, or (ii) 1.75 times the
monthly average of LifeScan's committed orders at the time.

     2.4 FORECASTS AND PURCHASE ORDERS. On or prior to December 31, March 31 and
June 30 and September 30 of each year, LifeScan shall provide Selfcare with a
written forecast of LifeScan's purchase requirements with respect to LS Products
to be purchased by it during the next twelve (12) months. The amount of LS
Products forecasted to be purchased by LifeScan in the first six months covered
by such forecast shall constitute a firm order for such LS Products. If the
amount of LS Products forecasted in the first three months of such forecast
period differs from that set forth in the prior quarterly forecast, such changed
amount shall constitute an offer to Selfcare to amend the prior period's
purchase order. Such offer shall, however, be deemed to have been rejected
unless accepted by Selfcare by notice within five days after receipt. With
respect to the fourth, fifth and sixth month covered by such

                                        3

<PAGE>   7



forecast, the amounts of LS Products set forth in such forecast shall constitute
a purchase order for LS Products to be delivered during such months. LifeScan's
forecast of its purchase requirements for the second half of each such 12-month
period shall be advisory only.


                                   ARTICLE III
                                CAPACITY PLANNING

     3.1 CAPACITY PLAN CONCEPTS. From time to time LifeScan may, pursuant to
this Article III, submit forecasts, referred to as Proposed Capacity Plans, to
Selfcare for the purpose of establishing the volumes of LS Products which, if
subsequently ordered by LifeScan and not delivered by Selfcare, will under
certain circumstances entitle LifeScan to exercise certain rights under its
Self-help License pursuant to Article VII. If such forecasts for LS Strips
exceeds certain levels, Selfcare shall be entitled, pursuant to this Article
III, to require LifeScan to make certain payments, referred to as Capital
Expenditure Make-up Payments, if LifeScan confirms its volume projections and
thereafter its orders fall short by certain amounts.

     3.2 PROPOSED AND BINDING CAPACITY PLAN DEFINITIONS. "Proposed Capacity
Plan" means, for any calendar year and for any LS Products, the amount thereof,
stated in terms of an average monthly purchase requirement, forecast in good
faith by LifeScan to be ordered for delivery during such calendar year in a
written projection of which LifeScan has given Selfcare notice as required
below. LifeScan shall deliver Proposed Capacity Plans to Selfcare one year prior
to the commencement of the calendar year to which they apply. Proposed Capacity
Plans must be explicitly identified with bold print in the cover letter or
transmittal form transmitting the document, and on each page of the document
proposed to constitute the Proposed Capacity Plan, as a "PROPOSED CAPACITY PLAN
PURSUANT TO THE SALES DISTRIBUTION AGREEMENT FOR TESTING SYSTEM FOR BLOOD
GLUCOSE."

     "Binding Capacity Plan" means with respect to any calendar year (i) in the
case of LS Strips, the Proposed Capacity Plan for such calendar year unless
Selfcare has given a Capital Requirements Notice in response to it which has not
been accepted by LifeScan, in which event the Binding Capacity Plan for such
calendar year for LS Strips shall be such other amount as LifeScan and Selfcare
shall agree and in the absence of any such agreement, the Yearly Minimum for
such calendar year pursuant to Section 4.4 and (ii) in the case of any other LS
Products, the Proposed Capacity Plan for such calendar year.

     3.3 BASE CAPACITY. "Base Capacity" means with respect to a Proposed
Capacity Plan for a calendar year, the greater of (i) the highest Binding
Capacity Plan for any then-prior calendar year with respect to which Selfcare
has given a Capital Requirements Notice which has been accepted by LifeScan and
(ii) in the case of calendar years 1997 through 2001, the Yearly Minimum set
forth in Section 4.4 with respect to such calendar year, and for 2002 and

                                        4

<PAGE>   8
   
                             CONFIDENTIAL TREATMENT
    
years thereafter, 115% of the LS Strips purchased by LifeScan during the 12-
calendar month period preceding the date of delivery of such Proposed Capacity
Plan, in each case stated on an average monthly basis.

     3.4 CAPITAL REQUIREMENTS NOTICES. If the average monthly purchase
requirement for LS Strips projected by LifeScan in its Proposed Capacity Plan
for a calendar year exceeds the applicable Base Capacity, Selfcare may give
written notice (a "Capital Requirements Notice") to LifeScan within sixty (60)
days after receipt of such Proposed Capacity Plan, indicating the capital
expenditures that Selfcare reasonably estimates in good faith that it will need
to make in order to meet LifeScan's projected demand. If Selfcare fails to
deliver a Capital Requirements Notice to LifeScan with respect to a Proposed
Capacity Plan, it shall become a Binding Capacity Plan and Selfcare shall not be
entitled to require LifeScan to make Capital Expenditure Make-up Payments
pursuant to Section 3.5 with respect to such Binding Capacity Plan.

   
     3.5 ACCEPTANCE AND REJECTION OF CAPITAL REQUIREMENTS NOTICES. If LifeScan
does not accept a Capital Requirements Notice by giving notice to Selfcare
within 30 days after receipt thereof, such Capital Requirements Notice shall be
deemed rejected. If Selfcare gives a Capital Requirements Notice and it is
rejected, Selfcare shall not be required to supply more LS Strips in the
calendar year to which the Capital Requirements Notice relates than the greater
of (i) the applicable Yearly Minimum or (ii) the maximum amount Selfcare can
economically produce without incurring capital expenditures other than those
necessary to maintain existing capacity and the Proposed Capacity Plan in
response to which such Capital Requirements Notice was given shall not be
effective for any purpose hereunder. If LifeScan accepts a Capital Requirements
Notice given in response to a Proposed Capacity Plan for a calendar year by
notice to Selfcare, such Proposed Capacity Plan shall become a Binding Capacity
Plan and if LifeScan thereafter fails to order for delivery during such calendar
year at least XXX of the number of strips projected to be purchased by LifeScan
in such Binding Capacity Plan, then LifeScan shall make a payment (a "Capital
Expenditure Make-up Payment") to Selfcare, promptly after written demand
therefor, in an amount determined by the following formula:
    

CEMP =       Cap Ex x (Required [DELTA] -Actual [DELTA] ) / Required [DELTA]

where,

CEMP =       Capital Expenditure Make-up Payment with respect to a calendar year

Cap Ex =     the lesser of the capital expenditures estimated by Selfcare in its
             Capital Requirements Notice or the actual capital expenditures made
             by Selfcare to increase LS Strip production capacity in response to
             the Binding Capacity Plan for such calendar year

<PAGE>   9
   
                             CONFIDENTIAL TREATMENT


Required [DELTA]=        the amount by which XXX of the Binding Capacity Plan 
                         for the calendar year at issue exceeds, in the case of 
                         calendar years through 2001, the Base Capacity for
                         such year and in the case of calendar years thereafter,
                         the total number of LS Strips projected to be purchased
                         by LifeScan in the Binding Capacity Plan for the 
                         calendar year prior to the year at issue
    

Actual [DELTA]=          the amount by which LifeScan's total purchases of LS 
                         Strips in the applicable Current Year exceeds, in the 
                         case of calendar years through 2001, the Base Capacity 
                         for such year and in the case of calendar years
                         thereafter, the total number of LS Strips projected to 
                         be purchased by LifeScan in the Binding Capacity Plan 
                         for the calendar year prior to the year at issue
   
     For example, with respect to a calendar year after 2001, if the Binding
Capacity Plan for the prior year is XXXXXXXXXXX, the Binding Capacity Plan for
the calendar year at issue is XXXXXXXXXXX, Selfcare gives and LifeScan accepts a
Capital Requirements Notice starting that Selfcare will be required to make
capital expenditures of XXXXXXXXXX to meet such increased demand and actually
spends somewhat more, and LifeScan's actual purchases in the year at issue are
XXXXXXXXXXX, LifeScan will be obligated to make a Capital Expenditure Make-up
Payment of XXXXXXXXXXX calculated as follows:

Cap Ex =                 XXXXXXXXXX
Required [DELTA]=        (XXX x XXXXXXXXXXX) - XXXXXXXXXXX, or XXXXXXXXXXX
Actual [DELTA]=          XXXXXXXXXXX - XXXXXXXXXXX or XXXXXXXXXXX
CEMP =                   XXXXXXXXXX  x (XXXXXXXXXXX - XXXXXXXXXXX) / XXXXXXXXXX
                         or XXXX of XXXXXXXXXX     or XXXXXXXXXXX
    

     3.6 CREDIT FOR CAPITAL EXPENDITURE MAKE-UP PAYMENTS. If LifeScan makes a
Capital Expenditure Make-up Payment with respect to purchases of LS Strips for a
calendar year (the "Payment Year"), then in each following calendar year
thereafter (a "Credit Year") in which LifeScan purchases more LS Strips than it
did in any prior year commencing with the year with respect to which such
Capital Expenditure Make-up Payment was required, LifeScan shall be entitled to
a credit against payments next due for LS Strips purchased thereafter. The
amount of any such credit shall equal the amount by which such Capital
Expenditure Make-up Payment exceeds the amount which would have been required
had LifeScan's purchases of LS Strips in the Payment Year been equal to its
purchases in the Credit Year, reduced by any credits taken with respect to any
prior Credit Years.

   
     For example, continuing the example in Section 3.5, if in the first year
after LifeScan makes the Capital Expenditure Make-up Payment of XXXXXXXXXXX,
LifeScan's purchases of LS Strips are XXXXXXXXXXX, LifeScan shall be entitled to
a credit calculated as follows:

     Cap Ex =            XXXXXXXXXX
     Required [DELTA]=   XXXXXXXXXXX
     Actual [DELTA]=     XXXXXXXXXXX - XXXXXXXXXXX or XXXXXXXXXXX
     CEMP =              XXXXXXXXXX  x XXXXXXXXXXXX - XXXXXXXXXXXX / XXXXXXXXXX
                         or XXXX of XXXXXXXXXX or XXXXXXXXXXX
     Credit =            XXXXXXXXXXX - XXXXXXXXXXX or XXXXXXXXXXX

If in the second year after LifeScan makes the Capital Expenditure Make-up
Payment of XXXXXXXXXXX LifeScan's purchases of LS Strips are XXXXXXXXXXX,
LifeScan shall be entitled to a credit calculated as follows:

     Cap Ex =            XXXXXXXXXX
     Required [DELTA]=   XXXXXXXXXXX
     Actual [DELTA]=     XXXXXXXXXXX - XXXXXXXXXXX or XXXXXXXXXXX
     CEMP =              XXXXXXXXXX  x XXXXXXXXXXXX - XXXXXXXXXXXX / XXXXXXXXXXX
                         or XXXX of XXXXXXXXXX or XXXXXXXXXX
     Credit              = Difference in payment - prior credit or
                         XXXXXXXXXXXX - XXXXXXXXXX) - XXXXXXXXXXX or XXXXXXXXXX.
    

     3.7 COOPERATION REGARDING CAPITAL EXPENDITURE MAKE-UP PAYMENTS. LifeScan
acknowledges that its obligation to make Capital Expenditure Make-up Payments is
intended in part to facilitate financing which Selfcare may seek for the purpose
of obtaining capital to expand its production capacity of LS Strips to meet
LifeScan's demand. Prior to disclosing to any potential source of financing
other than a bank, insurance company, pension fund or other institutional
lender, any of the terms of any Transaction Agreement, however, Selfcare shall
require that such potential source of financing agree to be subject to
confidentiality obligations that are substantially equivalent to those binding
upon Selfcare under Article V of the Master Agreement. LifeScan agrees to permit
an assignment of Selfcare's rights to such payment to finance such capital
expenditures and to deliver such further instruments as Selfcare or a proposed
source of financing may reasonably require to obtain any such financing,
including an agreement not to exercise any right of set off against any assignee
of the right to receive Capital Expenditure Make-up Payments providing financing
to Selfcare. LifeScan shall not, however, be required to incur any out-of-pocket
expense or otherwise waive any right or claim against Selfcare.

                                   ARTICLE IV
                            MARKET DEVELOPMENT RIGHTS

     4.1 INITIAL SALES RESTRICTIONS. As an inducement to LifeScan to invest the
monies and management resources necessary to develop the market for LS Products,
Selfcare agrees that, except as provided in Sections 4.3, 4.4 and 4.5, Selfcare
shall not, to the extent such restrictions are permitted by applicable law:

          (a) sell Compatible Products other than to LifeScan anywhere in the
     world; or

          (b) sell Complete System Products other than to LifeScan anywhere in
     the world.

     4.2 RESERVED MARKETING RIGHTS. No term of this Agreement shall prohibit
Selfcare from manufacturing and selling without restriction Test Strips for
measuring blood glucose designed to be used, and usable without an additional
electronic component not supplied by Selfcare, only with Instruments not
manufactured or sold by Selfcare. The foregoing, however, shall not constitute a
license or permission of use under any patent, patent application or other
intellectual property rights owned or used by or licensed to LifeScan or JJDC or
any of their Affiliates.

     4.3 FAILURE TO PURCHASE YEARLY MINIMUM. Following any failure by LifeScan
to purchase the applicable Yearly Minimum of LS Strips with respect to a
calendar year, the restriction set forth in Section 4.1(b) shall terminate and
thereafter Selfcare shall be free to sell Complete System Products other than
Compatible Products anywhere in the world, but shall not sell Complete System
Products to or through an Established Person. On or before January 31 of each
calendar year, LifeScan shall be entitled to order LS Strips and pay for such LS
Strips at the time of placing an order for the purpose of satisfying its Yearly
Minimum purchase requirements for the previous calendar year. LifeScan may
elect, by giving notice to such effect to Selfcare not later than March 1 of
each year, to have the purchases made during the prior January counted, in whole
or in part, as purchases in the prior year. LS Strips shall be deemed to be
"purchased" for purposes of the preceding sentence only when paid for by
LifeScan, regardless of whether they have been delivered. Selfcare shall not be
obligated to deliver LS Strips ordered pursuant to this Section 4.3 sooner than
it is able to do so exercising commercially reasonable efforts.

     4.4 YEARLY MINIMUMS:

         (a) If Selfcare obtains FDA Clearance of the Glucose System by June 1,
     1997 and has delivered to LifeScan the quantities of LS Product shown on
     Schedule 4.4 (or such lesser volumes as LifeScan has ordered for delivery
     on or prior to such date), the "Yearly Minimum" of LS Strips for the
     succeeding calendar years shall be the applicable amount indicated in the
     following table:

          (b) If by January 31, 1998, Selfcare shall have obtained FDA Clearance
     of the Glucose System and shall have delivered the quantities of LS
     Products stated in Schedule 4.4 (or such lesser volumes as LifeScan has
     ordered for delivery on or prior to such date), then the Yearly Minimum of
     LS Strips shall be the applicable amount indicated in the following table

          (c) If the Clearance/Delivery Date, as defined below, occurs after
     June 1, 1997 and before January 31, 1998, then the Yearly Minimums for each
     calendar year commencing 1998 shall be the weighted average of the amounts
     shown in the table in Section 4.4(a) and the amounts shown in the table in
     Section 4.4(b), with the weighting of the amounts shown in the table in
     Section 4.4(a) based on the number of days from the Clearance/Delivery Date
     until January 31, 1998, and the weighting of the amounts shown in the table
     in Section 4.4(b) based on the number of days between June 1, 1997 until
     the Clearance/Delivery Date. The Clearance/Delivery Date shall be the date
     on which the following two conditions are satisfied: (i) Selfcare has
     obtained FDA Clearance for the Glucose System and (ii) Selfcare has
     delivered to LifeScan the quantity of LS Products stated in Schedule 4.4 or
     such lesser amount as LifeScan shall have ordered for delivery through the
     date on which Selfcare obtains FDA clearance for the Glucose System.

          (d) If the Clearance/Delivery Date is after January 31, 1998, then the
     Yearly Minimum of LS Strips shall be as provided in Section 4.4(b) except
     that the dates shall be extended as agreed by LifeScan and Selfcare and, if
     they cannot agree, as determined by arbitration pursuant to Section 6.2 of
     the Master Agreement, and the fixed numbers of LS Strips shall be reduced
     as agreed by LifeScan and Selfcare and, if they cannot agree, determined by
     arbitration pursuant to Section 6.2 of the Master Agreement.

     4.5 INTRODUCTION OF COMPETING ELECTROCHEMICAL SYSTEM. If there is Market
Introduction on or before December 31, 2001 anywhere in the world by LifeScan or
any Affiliate of LifeScan of any electrochemical testing system designed to be
capable of home use to measure the blood glucose and which is not supplied by
Selfcare, then:

          (a) If such Market Introduction occurs on or before December 31, 1999
     all restrictions set forth in Section 4.1 shall terminate.

          (b) If such Market Introduction occurs during the years 2000 or 2001,
     the restriction set forth in Section 4.1(b) shall terminate and thereafter
     Selfcare shall be free to sell Complete System Products other than
     Compatible Products anywhere in the world.

     4.6 NOTICE. LifeScan will give notice to Selfcare of any actions by
LifeScan or any of its Affiliates of which the President of LifeScan becomes
aware which are relevant to the restrictions applicable to Selfcare pursuant to
Article IV.

                        REQUIRED PURCHASE OF LS PRODUCTS

   
     If Selfcare has obtained FDA Clearance of the Glucose System after November
1, 1996 and before June 1, 1997, LifeScan agrees to purchase and pay for a
minimum of XXXXXXXXXX LS Strips in 1998 and XXXXXXXXXX LS Strips in 1999. If
Selfcare has not obtained FDA Clearance of the Glucose System by June 1, 1997,
LifeScan may elect, by giving notice to Selfcare on or before the earlier of (i)
the date which is sixty (60) days after Selfcare has obtained FDA Clearance of
the Glucose System and (ii) April 1, 1998, to have the minimum purchase
obligations set forth in the preceding sentence appropriately reduced and the
amount of such reduction determined by agreement of the parties, or failing such
agreement, by arbitration pursuant to Section 6.2 of the Master Agreement. If
LifeScan fails to make such election, such minimum purchase obligations shall
remain unchanged.

                                      PRICE

     6.1 LS PRODUCTS OTHER THAN LS STRIPS. The base price for LS Products other
than LS Strips purchased by LifeScan hereunder shall be the cost at which such
LS Products would be valued, on a FIFO basis under United States generally
accepted accounting principles but including appropriate allocations of
overhead, for reporting on the audited balance sheet of Selfcare at the end of
the accounting period in which such LS Products is manufactured. Selfcare shall
be entitled to select from time to time such accounting period not longer than a
calendar year as it may elect for the purpose of this Section 6.1 so long as in
changing accounting periods, no cost data shall be taken into account more than
once. Unless LifeScan otherwise requests, Selfcare will contract for products
other than LS Strips solely in U.S. Dollars. If Selfcare is permitted to
contract for products other than LS Strips in a currency other than U.S.
Dollars, pricing for LS Products pursuant to Section 6.1 shall be calculated
based on the currencies in which such costs are incurred by Selfcare and shall
be converted to U.S. Dollars at the prices at which such currencies could be
purchased with U.S. Dollars prevailing at the time Selfcare prepares invoices
for such LS Products.

     6.2 BASE STRIP PRICES. In each calendar year, the base price per LS Strip
(the "Base Strip Prices") purchased by LifeScan hereunder shall depend on the
annualized total number of LS Strips purchased by LifeScan during such year, as
set forth below, subject to reduction as provided in this Section 6.2:

Each of the base prices per strip set forth above shall be decreased by $XXXX,
for the prices stated in U.S. Dollars, and XXXXX Pounds Sterling for the prices
stated in Pounds Sterling, for the remainder of the term of this Distribution
Agreement if LifeScan pays to Selfcare $XXXXXXXXX and enters into a Distribution
Agreement with respect to the first System to be offered to LifeScan pursuant to
Section 3.2 of the Master Agreement. The price to be paid by LifeScan for LS
Strips ordered in any year shall be the applicable Base Strip Price adjusted as
provided in Sections 6.4 and 6.5 through the date of invoicing.
    

     6.3 PAYMENT IN LOCAL CURRENCY FOR LS STRIPS. LifeScan will be invoiced in
Pounds Sterling and pay in Pounds Sterling for LS Strips which have production
cost in Pounds Sterling. LifeScan will be invoiced in U.S. Dollars and pay in
U.S. Dollars for LS Strips which have production cost in U.S. Dollars. If
Selfcare manufactures outside of United Kingdom and United States, it will not
be protected on currency fluctuations unless LifeScan otherwise agrees.

     6.4 ADJUSTMENT BASED ON LS RESALE PRICE. Each calendar year (a "Price
Year") the strip prices shall be increased (but never decreased) in proportion
to the increase, if any, in the LS Resale Price from (i) the calendar year
beginning two years prior to such Price Year to (ii) the calendar year beginning
one year prior to such Price Year provided that if the LS Resale Price shall
decrease from one calendar year to the next, the LS Resale Price shall be deemed
to have remained at the level in effect prior to such decrease until thereafter
exceeded.

     "LS Resale Price" means the weighted average world-wide price at which
LifeScan resells LS Strips.

        6.5 ADJUSTMENT BASED ON SELFCARE PROFITABILITY. If the sale of LS
Strips to LifeScan on the pricing terms provided in this Agreement ceases to be
profitable for Selfcare, the parties agree that in lieu of the price otherwise
applicable under this Agreement, the price for LS Strips shall be such amount as
gives Selfcare a commercially reasonable profit. The Parties agree to negotiate
in good faith with regard to any such price adjustment. The determination of the
amount of such profit shall include comparison with other Selfcare product lines
as well as other similar OEM arrangements, and shall take into account
reasonable allocations of Selfcare's overhead. If Selfcare claims that it is
entitled to a pricing adjustment under this Section 6.5, LifeScan shall be
entitled to audit Selfcare's books and records to the extent necessary to verify
Selfcare's claims with regard to its profitability.

                          FAILURE BY SELFCARE TO SUPPLY

     7.1 DEFINITIONS RELATING TO SELF-HELP LICENSING. "Required Amount" means,
with respect to any calendar year, the lesser of (i) the amount of LS Product
ordered by LifeScan for delivery during such period or (ii) the amount of
product forecast to be ordered by LifeScan for delivery during such calendar
year, in the Binding Capacity Plan, in each case calculated ratably on a monthly
basis.

     A "Supply Default" shall occur if:

          (a) Selfcare fails to ship to LifeScan on a cumulative basis during
     any period of four consecutive calendar months (the "First Period") the
     Required Amount of any LS Products for such First Period; and

          (b) after notice of such failure by LifeScan to Selfcare, Selfcare
     fails, during the course of the four consecutive calendar months
     immediately following such notice (the "Second Period"), to ship to
     LifeScan an amount of such LS Products equal to the lesser of (i) the
     amount of such product for which LifeScan requests delivery during the
     Second Period and (ii) the sum of the Required Amount for the Second Period
     and the short fall in Selfcare's deliveries of such product from the
     Required Amount during the First Period.

     "Self-help License" means a nonexclusive license on the terms set forth in
this Article VII of Selfcare's rights in patents and know-how used in making,
using or selling the LS Products as to which either a Supply Default has
occurred or Selfcare's production capabilities have been affected by Force
Majeure, whichever is applicable, to make, use and sell such LS Products for so
long as Selfcare fails to supply the Required Amount of such LS Products. Any
such license shall permit LifeScan to authorize others to make any such LS
Products exclusively for LifeScan so long as such parties agree to terms to
protect the confidentiality of Selfcare's Confidential Information that are
substantially equivalent to those

                                       13

<PAGE>   17


set forth in Article V of the Master Agreement. In no event, however, shall
LifeScan be entitled to authorize any Person other than Persons which are
Affiliates of LifeScan, for so long as they remain Affiliates, to print Test
Strips.

     7.2 LICENSE ON SUPPLY DEFAULT. Selfcare hereby grants to LifeScan a
Self-help License, but LifeScan shall not exercise any right under such license
unless and until Selfcare shall have acknowledged, or an arbitrator pursuant to
Section 6.2 of the Master Agreement, shall have determined (i) that a Supply
Default shall have occurred other than as a result of Force Majeure or (ii) that
the conditions to the exercise by LifeScan of its rights under the Self-help
License pursuant to Section 7.3 or 7.4 have been satisfied.

     7.3 COMMUNICATIONS FOLLOWING FORCE MAJEURE. If Selfcare becomes aware that
as a result of Force Majeure, a Supply Default is likely to occur, Selfcare will
give notice to LifeScan indicating the extent to which its capability of
supplying LS Products has been affected, together with an estimate of the time
anticipated for Selfcare to restore its manufacturing capability in order to
meet the applicable Binding Capacity Plan. If such period is less than eight (8)
months from the date of the occurrence of the Force Majeure, Selfcare shall
diligently attempt to restore its production capabilities and LifeScan shall not
be entitled to exercise any of its rights under the Self-help License. If
Selfcare estimates that it will take more than eight (8) months from the date of
the occurrence of the Force Majeure to restore such manufacturing capability,
LifeScan may, if it determines in good faith that it could build an alternative
manufacturing capability for the affected LS Products in a shorter time frame,
give notice (a "Supply Timing Notice") to such effect to Selfcare within thirty
(30) days after receipt of Selfcare's estimate. Within thirty (30) days after
receipt of such notice, Selfcare shall elect whether to reduce its estimate to
the period estimated by LifeScan to build such capability, and failing to give a
notice, shall be deemed to have elected not to alter its estimate.

     7.4 RIGHTS FOLLOWING FORCE MAJEURE. If LifeScan has given a Supply Timing
Notice and Selfcare fails to elect to reduce its estimate to the period
estimated by LifeScan to build its own capability, or if following the
occurrence of a Force Majeure affecting the supply of LS Products, Selfcare
fails diligently to attempt to re-establish its supply capabilities, LifeScan
shall be permitted to exercise all of its rights under the Self-help License. If
Selfcare elects to reduce its estimate to meet LifeScan's estimated time to
start a supply of the affected LS Product and thereafter fails within a time
period equal to one hundred and fifteen percent (115%) of the period from the
occurrence of the Force Majeure until the revised estimated date to have
production capability restored, to restore such production capability and resume
supply of LS Products to LifeScan in the Required Amount, then (i) LifeScan
shall be entitled to exercise its rights under the Self-help License, and (ii)
Selfcare will, if it elects to commence resupplying such product, supply without
charge LS Product in an amount equal to the average monthly portion of the
Required Amount of such LS Product in effect during the time Selfcare was
rebuilding its production facilities, multiplied by the number of months which
Selfcare estimated it would take to rebuild.

     7.5 RESTORATION OF SUPPLY BY SELFCARE. If LifeScan is permitted pursuant to
this Article VII to exercise its rights under the Self-help License, Selfcare
shall no longer be required to supply the LS Product with respect to which
LifeScan has become so permitted. Selfcare, however, shall be entitled to
restart supplying such LS Products as provided in this Section 7.5. If after
LifeScan has become entitled to exercise its rights under the Self-help License
pursuant to this Article VII, LifeScan expends funds in order to establish a
production capability as permitted by such license, then, except as provided
below in this Section 7.5, Selfcare must, in order to require LifeScan to
discontinue establishment of or use of such production capability and restart
purchases of the affected LS Products from Selfcare, agree to reimburse LifeScan
with the amount it has expended on equipment, personnel and other out-of-pocket
costs (collectively, "Self-help Costs") in establishing such production
capability, such reimbursement to be in eight (8) equal quarterly payments
commencing three (3) months after Selfcare restarts supplying LifeScan. If
LifeScan has become entitled to exercise its rights under the Self-help License
pursuant to this Article VII and fails to establish a supply capability
sufficient to meet the applicable Required Amount within 115% of the period
specified in LifeScan's Supply Timing Notice, then LifeScan shall not be
entitled to reimbursement of its Self-help Costs if Selfcare elects to restart
supply of the applicable LS Products.

   
     7.6 TERMS, ROYALTIES. Any LS Products produced by LifeScan pursuant to the
Self-help License granted hereby must be sold by it only in the manner provided
for in Section 2.1 hereof and otherwise in accordance with all of the terms of
this Distribution Agreement. LifeScan shall not pay for such LS Products in
accordance with Article VI but rather shall pay a royalty to Selfcare equal to:
(i) with respect to LS Products other than LS Strips, XXX% of LifeScan's gross
sales revenue of such LS Products sold, net of returns, discounts and
allowances, and (ii) with respect to LS Strips, the greater of (x) XXX% of
LifeScan's gross sales revenue of LS Strips sold, net of returns, discounts and
allowances or (y) on a per strip basis, Selfcare's average per strip gross
margin for the calendar year immediately preceding the date on which the
conditions giving rise to LifeScan's right to exercise its Self-help License
occur; provided that, in the event that Selfcare willfully failed to deliver the
requisite amount of LS Strips, then such royalty shall be the amount specified
in clause (x), even if the amount specified in clause (y) is greater.
    

     7.7 COOPERATION. Pursuant to the Self-help License, LifeScan shall have the
right to receive from Selfcare the tangible embodiment of the information and
intellectual property licensed under the Self-help License, including without
limitation copies of all specifications, drawings, notebooks and bills of
materials, such assistance as LifeScan may reasonably require in its exercise of
rights under such Self-help License, including, without limitation, providing
LifeScan with appropriate know-how and training in the manufacture of LS
Products. It is the intention of LifeScan and Selfcare that the Self-help
License constitutes a license of intellectual property as defined in Title 11,
U.S. Code, and that LifeScan receive all of the benefits of Section 365(n) of
the Bankruptcy Code (or successor statute or provision) with respect to such

license. Further, all rights, powers and remedies of LifeScan provided herein
are in addition to and not in substitution for any and all other rights, powers
and remedies now or hereafter existing at law or in equity (including without
limitation Title 11, U.S. Code) in the event of a filing of a petition for
relief by or with respect to Selfcare under such Title 11 (or successor
statute). LifeScan will reimburse Selfcare's reasonable and necessary
out-of-pocket expenses incurred in connection with such assistance. Such license
and any communications pursuant thereto is subject to the confidentiality
provisions set forth in the Master Agreement. Except as contemplated by the
definition of Self-help License, LifeScan shall not grant sublicenses of the
license granted to it pursuant to this Article VI.

     7.8 EXCLUSIVE REMEDY. The exercise by LifeScan of its rights under the
Self-help License shall be the sole and exclusive remedy for failure of Selfcare
to supply LS Product, unless such failure was willful on the part of Selfcare,
in which case LifeScan shall have the benefit of any additional remedy to which
it may be entitled by law.

          (c) Each indemnified party agrees to give the indemnifying party
     proper written notice of any matter upon which such indemnified party
     intends to base a claim for indemnification (an "Indemnity Claim") under
     Article 8. The indemnifying party shall have the right to participate
     jointly with the indemnified party in the indemnified party's defense,
     settlement or other disposition of any Indemnity Claim. With respect to any
     Indemnity Claim relating solely to the payment of money damages and which

     or other equitable relief or otherwise adversely affect the business of the
     indemnified party in any manner, and as to which the indemnified party
     shall have acknowledged in writing the obligation to indemnify the
     indemnified party hereunder, the indemnifying party shall have the sole
     right to defend, settle or otherwise dispose of such Indemnity Claim, on

     evidence of its ability to pay any damages claimed and with respect to any
     such settlement shall have obtained the written release of the indemnified
     party from the Indemnity Claim. The indemnifying party shall obtain the
     written consent of the indemnified party, which shall not be unreasonably
     withheld, prior to ceasing to defend, settling or otherwise disposing of

                                   ARTICLE IX
                         AGREEMENTS REGARDING TECHNOLOGY

     9.1 INFRINGEMENT OF SELFCARE'S TECHNOLOGY. LifeScan and Selfcare shall each
notify the other as soon as practicable after it becomes aware of any
infringement by a third party of, or unlawful use by a third party of,
Selfcare's proprietary technology. Either party may

                                       18

<PAGE>   22


prosecute and defend any action or proceeding which it deems necessary in
connection with any infringement by a third party of a patent-protected
technology incorporated in LS Products. Any and all damages recovered in any
such action shall first be applied to pay all costs and expenses of any such
action. Any remaining recovery shall be shared by both parties in accordance
with the damage sustained by each as a result of such infringement. If the
recovery in any such action is not sufficient to pay any and all costs of such
action or proceeding, such costs shall be borne entirely by the parties which
incurred them. In any such case, the party initiating the prosecution shall
afford the other party an opportunity to be involved in all proceedings.

     9.2 U.S. AND EUROPEAN PATENT CONVENTION PATENT CONFLICTS. Selfcare agrees
to defend, at its own expense, and to pay all costs and damages awarded against
LifeScan based on, any and all claims by third parties arising from actual or
alleged infringement by LS Products of any U.S. patent or patent issued by a
participant in the European Patent Convention; provided that Selfcare's
obligation to pay such costs and damages under this Section 9.2 shall not apply
to the extent that such actual or alleged infringement arises out of
modifications to LS Products made by LifeScan; and provided that Selfcare's
obligation to pay such costs and damages shall be subject to and limited by the
following provisions of this Section 9.2. In the event that LifeScan receives a
claim or notice of a claim that is or may be subject to indemnification under
this Section 9.2, LifeScan shall (i) give Selfcare prompt written notice of such
claim or notice of claim, (ii) cooperate with Selfcare at Selfcare's expense in
every reasonable manner in the defense of such claim, and (iii) permit Selfcare
to assume and control the defense thereof at Selfcare's cost and expense,
provided that LifeScan shall have the right, at its option and at its expense,
to participate in the defense of such claim through counsel of its own choosing.
If infringement is held to exist, or if either party determines that a finding
of infringement is likely, the parties agree to discuss in good faith
alternative arrangements under which the liability of the parties could be
reduced, including possible revisions to the infringing material so as to make
it non-infringing, or arranging to procure for LifeScan the right to continue
using the infringing material to the extent permitted by this Distribution
Agreement, provided that neither party shall be obligated to agree to any
particular alternative arrangements under this sentence and neither party shall
have any liability for failing to agree upon any such alternative arrangements.
Notwithstanding anything else in this Distribution Agreement, if LifeScan is not
enjoined from selling LS Products as a result of any actual infringement of a
U.S. patent or patent issued by a participant in the European Patent Convention,
Selfcare's liability to LifeScan under this Section 9.2 shall be limited to
future amounts payable by LifeScan to Selfcare hereunder in respect of purchases
of LS Products, and shall be collected by LifeScan solely by set-off against
such amounts as they accrue, provided that if there exist any unpaid amounts due
under this Section 9.2 at the termination of this Distribution Agreement,
Selfcare shall be required to pay such amount in cash up to the amount of its
liability under this Section 9.2 upon such termination.

     9.3 PATENT CONFLICTS IN OTHER COUNTRIES. At least sixty (60) days prior to
commencement of the sale of LS Products outside of the United States and
countries which are

                                       19

<PAGE>   23







participants in the European Patent Convention, LifeScan shall give notice to
Selfcare indicating that it plans to commence the sale of LS Products in such a
country. Following such notice, Selfcare will arrange for a search of patent
conflicts in each such country and, after completion of such search, notify
LifeScan whether it is prepared to expand the provisions of Section 9.2 to apply
to such country's patents. If LifeScan gives a notice contemplated by this
Section 9.3 and Selfcare fails thereafter to notify LifeScan that it is prepared
to expand the application of Section 9.2 to apply to the patents of such
country, then LifeScan shall not sell LS Products in such country and the
minimum purchase obligations of LifeScan pursuant to Section 4.4 shall be
equitably adjusted.

     9.4 TECHNICAL INFORMATION NECESSARY FOR MARKETING. Selfcare shall furnish
to LifeScan any technical information or instructions necessary for the
marketing of LS Product. LifeScan acknowledges and agrees that all such
technical information communicated by Selfcare to LifeScan shall be the
exclusive property of Selfcare and shall be deemed to be "Confidential
Information" within the meaning of Article V of the Investment Agreement.
LifeScan further acknowledges and recognizes that Selfcare claims exclusive
ownership of its proprietary technology relating to the Glucose System and
further undertakes that it will not represent that it has any title to or right
of ownership in such technology.

made in U.S. Dollars by LifeScan to Selfcare for each shipment of LS Products
not later than thirty (30) days after the date of the invoice therefore which
shall not be earlier than the date of shipping by Selfcare, except that in the
case of purchase prices which cannot be determined until a later date (e.g., the
cost of Instruments based on a GAAP Inventory cost, the cost of LS Strips based
on annual purchases), the parties shall agree on an estimated cost, which
LifeScan shall remit within such 30-day period, and appropriate adjustments
shall be promptly made after determination of the definitive purchase prices.
Payments shall be by check drawn on the regular account of LifeScan.

     10.2 PRODUCT WARRANTIES. Selfcare represents and warrants to LifeScan that

limitation, those enforced by the FDA (including compliance with good
manufacturing practices). In the event that any LS Products, upon delivery, do
not conform as aforesaid, LifeScan's remedy shall be limited to the repair or
replacement (at Selfcare's option) of such nonconforming LS Products within a
reasonable period of time. In no event shall Selfcare be liable for indirect,
consequential or money damages, whether in contract, tort or otherwise. LifeScan
agrees that it will deal directly with its customers concerning warranty matters
relating to LS Products, and Selfcare will not be required to participate in
such dealings.

     10.3 AGREEMENT TERM. The term of this Distribution Agreement shall commence
on the date hereof and shall remain in effect through December 31, 2010.

provisions of any applicable jurisdiction's securities laws and any rules and
regulations thereunder;

     (vii) Buyer has no existing short position with respect to the common stock
of Seller and agrees not to enter into any short sales or other hedging
transactions with respect to the common stock of Seller at any time after the
execution of this Agreement by Buyer and prior to the date on which the
Preferred Shares become convertible. Buyer further agrees that, at all times
after the execution of this Agreement by Buyer and prior to the date on which
the Preferred Shares becomes convertible, it will keep its purchase of the
Shares confidential, except as required by law and except as necessary in the
ordinary course of Buyer's business;


                                        2

<PAGE>   3



     (viii) Buyer understands that the Preferred Shares have not been registered
under the Securities Act and are being offered and sold to it under Regulation
S, which provides an exemption from registration otherwise required by the
Securities Act, and that Seller is relying upon the truth and accuracy of the
representations, warranties, agreements, acknowledgments and understandings of
Buyer set forth herein in order to determine the applicability of such
provisions. Accordingly, Buyer agrees to fully indemnify, defend and hold
harmless Seller, its management and its affiliates, employees and agents from
any and all claims, actions and causes of action whatsoever which may result
from a breach of the representations, warranties, agreements, acknowledgments
and understandings of Buyer set forth in this Agreement;

     (ix) Any offering documents received by Buyer include statements to the
effect that the Shares have not been registered under the Securities Act and
such securities may not be offered or sold in the United States or to U.S.
Persons during the Restricted Period; Buyer acknowledges receipt and review of
the following offering documents: (a) a copy of this Agreement, (b) a
Certificate of Designation of Preferred Stock, (c) Seller's final prospectus
dated August 6, 1996, (d) Seller's Form 10-QSB for the quarterly period ending
June 30, 1996, and (e) a Supplemental Offering Memorandum dated October 2, 1996;

     (x) Buyer, in making the decision to purchase the Preferred Shares
subscribed for, has relied upon independent investigations made by it and has
not relied on any information or representations made by third parties;

     (xi) In the event of resale of the Shares during the Restricted Period,
Buyer shall provide a written confirmation or other written notice to any
distributor, dealer, or person receiving a selling concession, fee, or other
remuneration in respect of the Shares stating that such purchaser is subject to
the same restrictions on offers and sales that apply to the undersigned, and
shall require that any such purchaser shall provide such written confirmation or
other notice upon resale during the Restricted Period;

     (xii) Buyer has not taken any action that would cause Seller to be subject
to any claim for commission or other fee or remuneration by any broker, finder,
or other person and Buyer hereby indemnifies Seller and its directors, officers
and affiliates against any such claim caused by the actions of Buyer or any of
its employees or agents;

     (xiii) Buyer acknowledges that the purchase of the Shares is a speculative
investment involving a high degree of risk and any estimates and predictions
that may have been made by the Company merely represent predictions of future
events which may or may not occur and are based on assumptions which may or may
not occur. As a consequence, such predictions may not be relied upon to indicate
the actual results which might be attained. Buyer has carefully read the
Supplemental Offering Memorandum and understands and has evaluated the risks of
a purchase of the Shares. Such risks are set forth in the section entitled "Risk
Factors" of the Company's final prospectus dated August 6, 1996, and are updated
in the Supplemental Offering Memorandum dated October 2, 1996; and


                                        3

     (xiv) Buyer represents and warrants that if Buyer is executing this
Agreement in a representative or fiduciary capacity, Buyer has full power and
authority to execute and deliver this Agreement on behalf of the subscribing
corporation, partnership, trust or other entity for whom Buyer is executing this
Agreement, and such corporation, partnership, trust or other entity has full
right and power to enter into and perform this Agreement.

3.   SELLER'S REPRESENTATIONS AND COVENANTS

     Seller represents and warrants to Buyer as follows:

     (i) Each of Seller and its subsidiaries, if any, have been duly
incorporated and are validly existing and in good standing under the laws of
their respective jurisdictions of incorporation. Seller is a "Domestic Issuer"
and a "Reporting Issuer," as such terms are as defined by Rule 902 of Regulation
S. Seller has registered its common stock pursuant to Section 12(b) or (g) of
the Securities Exchange Act of 1934, as amended (the "Exchange Act"), is in full
compliance with all reporting requirements of either Section 13(a) or 15(d) of
the Exchange Act, and Seller's common stock trades on the American Stock
Exchange;

     (ii) Seller has furnished Buyer with copies of Seller's Form 10-QSB for the
quarterly period ending June 30, 1996, the final prospectus dated August 6,
1996, and the Supplemental Offering Memorandum dated October 2, 1996. The
aforementioned documents do not, as of the respective date of each, include an
untrue statement of a material fact or omit to state any material fact necessary
in order to make the statements in said documents, in light of the circumstances
under which they were made, not misleading;

     (iii) Seller has not offered the Shares to any person in the United States,
any identifiable group of U.S. citizens abroad, or to any U.S. Person in
violation of the Securities Act;

     (iv) At the time the buy order was originated, Seller reasonably believed
Buyer was outside the United States and was not a U.S. Person;

     (v) Seller and/or its agents reasonably believe that the sale of Preferred
Shares has not been prearranged with a buyer in the United States;

     (vi) Seller has not conducted any "directed selling efforts" with respect
to the Preferred Shares;

     (vii) The Shares when issued and delivered will be duly and validly
authorized and issued, fully-paid and nonassessable and will not subject the
holders thereof to personal liability by reason of being such holders. There are
no preemptive rights of any shareholder of Seller with respect to the Shares;


                                        4

<PAGE>   5



     (viii) This Agreement has been duly authorized, validly executed and
delivered on behalf of Seller and is a valid and binding agreement in accordance
with its terms, subject to general principles of equity and to bankruptcy or
other laws affecting the enforcement of creditors' rights generally;

     (ix) The execution and delivery of this Agreement and the consummation of
the issuance of the Shares and the transactions contemplated by this Agreement
do not and will not conflict with or result in a breach by Seller, or any of its
subsidiaries, if any, of any of the terms or provisions of, or constitute a
default under, the Certificate of Incorporation or bylaws of Seller or any of
its subsidiaries, if any, or any indenture, mortgage, deed of trust or other
material agreement or instrument to which Seller or any of its subsidiaries, if
any, is a party or by which it or any of its subsidiaries, if any, any of their
respective properties or assets are bound, or any existing applicable decree,
judgment or order of any court, Federal or State regulatory body, administrative
agency or other governmental body having jurisdiction over Seller or any of its
subsidiaries, if any, or any of their respective properties or assets;

     (x) No authorization, approval or consent of any governmental body is
legally required for the issuance and sale of the Shares as contemplated by this
Agreement;

     (xi) Seller will issue one or more certificates representing the Preferred
Shares in the name of Buyer in such denominations to be specified by Buyer prior
to closing. Upon conversion of the Preferred Shares, Seller will issue one or
more certificates representing the Common Shares in the name of Buyer without a
restrictive legend and in such denominations to be specified by Buyer prior to
conversion. Seller further warrants that no instructions other than these
instructions, and instructions for a "stop transfer" until the end of the
Restricted Period, have been given to the transfer agent and also warrants that
the Shares shall otherwise be freely transferable by the Buyer on the books and
records of Seller subject to compliance with Federal and State securities laws.
Seller will notify the transfer agent of the date of completion of the Offering
and of the date of expiration of the Restricted Period. Nothing in this section
shall affect in any way Buyer's obligations and agreement to comply with all
applicable securities laws upon resale of the Shares;

     (xii) Seller has taken and will take no action that will affect in any way
the running of the Restricted Period or the ability of Buyer to resell the
Shares in accordance with Regulation S;

     (xiii) Seller will comply, provided that Buyer's representations herein are
true and correct and Buyer complies with its obligations under this Agreement,
with all applicable securities laws and regulations with respect to the sale of
the Shares, including but not limited to the filing of all reports required to
be filed in connection with the sale of the Preferred Shares pursuant to the
Securities Exchange Act of 1934 with the Securities and Exchange Commission or
any stock exchange or NASDAQ or any other relevant regulatory authority;


                                        5

<PAGE>   6



     (xiv) Seller agrees that it will not issue a press release or other
communication to the public containing Buyer's name or other identifying
information without Buyer's written consent unless required by law or the
requirements of the American Stock Exchange to do so; and

     (xv) Seller agrees to fully indemnify, defend and hold harmless Buyer, its
management and its affiliates, employees and agents from any and all claims,
actions and causes of action whatsoever which may result from a breach of the
representations, warranties, agreements, acknowledgments and understandings of
Seller set forth herein.

4.   REGISTRATION

     If upon conversion of the Preferred Shares effected by Buyer pursuant to
the terms of this Agreement and the Certificate of Designation following the
expiration of the Restricted Period, Seller fails to issue certificates for
Common Shares issuable upon such conversion to Buyer bearing no restrictive
legend for any reason other than Seller's reasonable good faith belief that the
representations and warranties made by Buyer in this Agreement were untrue when
made or other than because a legend is appropriate because of a change m
Regulation S, or the written interpretation thereof by the Securities and
Exchange Commission, occurring after the date hereof, then Seller shall be
required, at the written request of the Buyer m prior to the second anniversary
of this Agreement and at Seller's expense, to effect the registration of the
Common Shares issued upon such conversion of the Preferred Shares under the
Securities Act and relevant Blue Sky laws as promptly as is practicable. Upon
receipt of such written notice, Seller shall have the option to (i) register all
Common Shares issuable to Buyer upon conversion of the Preferred Shares, in
which case Seller shall cause the registration statement therefor (which may
include shares of common stock issued or to be issued to other shareholders) to
remain effective for the life of the Preferred Shares, or (ii) register only the
number of Common Shares already issued to Buyer, in which case Seller shall
cause the registration statement therefor to remain effective for sixty (60)
days following the effective date of such registration statement. Seller and the
Buyer shall cooperate in good faith in connection with the furnishing of
information required for such registration and the taking of such other actions
as may be legally or commercially necessary in order to effect such
registration. Seller shall file a registration statement within 40 days of
Buyer's demand therefor and shall use its reasonable best efforts to cause such
registration statement to become effective as soon as practicable thereafter and
in any event within 90 days of the date of the initial filing thereof. Such
efforts shall include, but not be limited to, promptly responding to all
comments received from the staff of the Securities and Exchange Commission
("SEC") and promptly preparing and filing amendments to such registration
statement which are responsive to the comments received from the staff of the
SEC. Once declared effective by the SEC, Seller shall cause such registration
statement to remain effective for the period of time noted above or, if shorter,
until the sale by Buyer of its Common Shares registered thereby. In the event
that Buyer has complied with its obligations hereunder but Seller has not
effected the registration of the Common Shares issuable upon the conversion of
the Preferred Shares under the Act and relevant Blue Sky Laws within ninety (90)
days after the date of filing of the

                                        6

<PAGE>   7



registration statement, Seller shall pay to Buyer by wire transfer, as
liquidated damages for such failure and not, as a penalty, an amount in cash
equal to $100,000; provided, however, that the aggregate amount payable to Buyer
hereunder shall be reduced so that the aggregate amounts payable to Buyer and to
other buyers in the Offering shall not exceed $400,000. Such payment shall be
made to Buyer immediately upon expiration of the 90-day period referenced in the
preceding sentence if the registration of the Common Shares is not effected by
such date; provided, however, that the payment of such liquidated damages shall
not relieve Seller from its obligations to register the Common Shares pursuant
to this Section 4. Seller's obligations under this Section 4 shall terminate
with respect to any Common Shares when and if Seller notifies Buyer that it will
remove any restrictive legend (i.e., a legend restricting transfer) on the
certificates representing such Shares and instructs the transfer agent to do so.

5.   CONVERSION

     Buyer shall have the right to convert the Preferred Shares into Common
Shares as follows:

     (i) The Preferred Shares shall become convertible, without the payment of
any additional consideration therefor, over a 180-day period from the date
hereof in accordance with the following schedule:

     No. of Shares                              Date on Which First Convertible
     -------------                              -------------------------------
     20% (the "First Installment")              December 14, 1996
     40% (the "Second Installment")             January 13, 1997
     60% (the "Third Installment")              February 12, 1997
     80% (the "Fourth Installment")             March 14, 1997
     100% (the "Fifth Installment")             April 13, 1997

   
     (ii) The Preferred Shares shall be convertible into that number of Common
Shares as is determined by dividing the sum of (A) the Purchase Price and (B)
any dividends on the Preferred Shares which are accrued but unpaid as of the
date of conversion, by the Conversion Price (determined as hereinafter provided)
in effect on the date of conversion. The "Conversion Price" shall be equal to
eighty-five and one-half percent (85.5%) of the average closing bid price of a
Common Share on the American Stock Exchange (or, in the event that such security
is not traded on the American Stock Exchange, such other national or regional
securities exchange or automated quotation system upon which such security is
listed and principally traded or, if no such price is available, the average per
share market value of such security as determined by a nationally recognized
investment banking firm or other nationally recognized financial adviser
retained by Seller for such purpose) during the five (5) trading days
immediately preceding the date the Conversion Notice (as defined in Section
5(iii) hereof), is received by Seller (such price or market value, the "Closing
Price"); PROVIDED, HOWEVER, that if the Conversion Price is equal to or greater
than $20.00, then the Conversion Price shall be $20.00 and if the Conversion
Price is equal to or less than $12.00, then the
    

                                        7

<PAGE>   8



Conversion Price shall be equal to the Closing Price; PROVIDED, FURTHER, that
whenever the Conversion Price is less than $8.75, then the Conversion Price
shall be deemed to be $8.75.

     (iii) Before Buyer shall be entitled to convert any Preferred Shares into
Common Shares, Buyer shall surrender the certificate or certificates therefor,
duly endorsed, at the office of Seller or of any transfer agent for the
Preferred Shares, and shall give written notice, which may be provided by
facsimile (the "Conversion Notice"), to Seller at such office that Buyer elects
to convert the same and shall state therein the name or names, including of any
of its nominees, in which Buyer wishes the certificate or certificates for
Common Shares to be issued, together with the applicable federal taxpayer
identification number, if any. Such notice shall specify which Installment or
Installments (as defined in Section 5(i) hereof, or portions thereof, are to be
converted. Seller shall, within five (5) business days after Seller's receipt of
the Conversion Notice (the "Deadline"), provided that Seller has received the
certificate or certificates therefor, duly endorsed, at the office of Seller or
of any transfer agent for the Preferred Shares prior to the Deadline, issue and
deliver at such office to Buyer, or to its nominee or nominees, a certificate or
certificates for the number of Common Shares to which Buyer shall be entitled,
together with a certificate or certificates representing any remaining Preferred
Shares which have not yet been converted. Upon the conversion of any Preferred
Shares, such shares shall be restored to the status of authorized but unissued
shares and may be reissued by Seller at any time.

     (iv) In the event of (A) any declaration by Seller of a record date for its
common stock for the purpose of determining the holders thereof who are entitled
to receive any dividend (other than a stock dividend payable in shares of common
stock or a cash dividend which is the same as cash dividends paid in previous
quarters) or other distribution, or (B) any capital reorganization of Seller,
any reclassification or recapitalization of the capital stock of Seller, any
merger or consolidation of Seller, and any transfer of all or substantially all
of the assets of Seller to any other corporation, or any other entity or person,
or any voluntary or involuntary dissolution, liquidation or winding up of
Seller, Seller shall mail to Buyer at least 20 days prior to the record date
specified therein, a notice specifying (1) the date on which any such record is
to be declared for the purpose of such dividend or distribution and a
description of such dividend or distribution, (2) the date on which any such
reorganization, reclassification, transfer, consolidation, merger, dissolution,
liquidation or winding up is expected to become effective, and (3) the time, if
any, that is to be fixed, as to when the holders of record of Common Shares (or
other securities) shall be entitled to exchange their Common Shares (or other
securities) for securities or other property deliverable upon such
reorganization, reclassification, transfer, consolidation, merger, dissolution,
liquidation or winding up. In the event of any merger or consolidation of
Seller, or any transfer of all or substantially all of the assets of Seller to
any other corporation, or any other entity or person, Buyer shall,
notwithstanding anything herein to the contrary, from and after the consummation
of such merger, consolidation or transfer, no longer be entitled to convert its
Preferred Shares into Common Shares and shall be entitled to receive only that
amount of consideration which Buyer would have received had it converted its
Preferred Shares into Common Shares immediately prior to such merger,
consolidation or transfer.

                                        8

<PAGE>   9



     (v) Seller shall reserve and keep available out of its authorized but
unissued Common Shares such number of Common Shares as shall from time to time
be sufficient to effect conversion of the Preferred Shares.

     (vi) Buyer hereby acknowledges and agrees that all certificates
representing Preferred Shares, prior to the date which is forty (40) days after
the issuance date of such Preferred Shares, shall bear the following legend:

          The shares of the Issuer represented by this certificate have been
          issued pursuant to Regulation S promulgated under the Securities Act
          of 1933, as amended ("Act"), and have not been registered under the
          Act. These shares may not be offered or sold within the United States
          or to or for the account of a "U.S. Person" (as that term is defined
          in Regulation S) until after the fortieth (40th) day following
          completion of the Regulation S offering of the Issuer pursuant to
          which these shares have been issued and only in compliance with the
          Act. The Issuer will notify the transfer agent of the date of
          completion of such offering.

     (vii) Buyer further acknowledges and agrees that, prior to April 14, 1997,
all certificates representing Preferred Shares shall contain a legend stating
that the Preferred Shares represented by such certificates are convertible, and
the specifics with respect thereto.

     (viii) Seller shall use its best efforts to issue and deliver to Buyer a
certificate or certificates for the number of Common Shares 'to which Buyer
shall be entitled within seven (7) business days after Buyer has fulfilled all
conditions required for conversion as set forth in this Agreement (the
"Deadline"). Seller understands that a delay in the issuance of the Common
Shares beyond the Deadline could result in economic loss to Buyer. As
compensation to Buyer for such loss, and not as a penalty, Seller agrees to pay
liquidated damages to Buyer for late issuance of Common Shares upon conversion
in the amount of one percent (1%) of the requested conversion amount, per day,
beginning on the eighth (8th) business day from the date of receipt by Seller of
a duly executed notice of conversion, provided that the original Preferred
Shares to be converted have been delivered to Seller within such time period,
all in accordance with this Agreement, the Preferred Shares and the requirements
of Seller's transfer agent. Said liquidated damages shall accrue each day
through the date the Common Shares are issued to Buyer upon conversion, and
shall be paid by wire transfer to an account designated by Buyer upon the
earlier to occur of (i) issuance of the Shares to Buyer, or (ii) each monthly
anniversary of the receipt by Seller of such Buyer's notice of conversion.
Nothing herein shall waive Seller's obligations to deliver Common Shares upon
conversion of the Preferred Shares or limit Buyer's right to pursue actual
damages for Seller's failure to issue and deliver Common Shares to Buyer in
accordance with the terms of this Agreement and the Preferred Shares.

     (ix) Seller agrees that, in addition to any other remedies which may be
available to Buyer, in the event Seller fails for any reason to effect delivery
to Buyer of certificates

                                        9

<PAGE>   10



representing Common Shares by the Deadline, Buyer may revoke the notice of
conversion by delivering a notice of such effect to Seller, whereupon Seller and
Buyer shall each be restored to their respective positions immediately prior to
delivery of such notice of conversion.

6.   THIRD PARTY BENEFICIARY. The parties acknowledge and agree that Shoreline
Pacific, the Institutional Division of Financial West Group ("Shoreline
Pacific"), shall be deemed a third party beneficiary of Seller's agreements and
representations set forth in this Agreement, entitled to enforce the terms
thereof; provided, however, that Shoreline Pacific's rights hereunder (i) shall
not be greater than the rights Buyer then has, and (ii) shall be subject to the
same defenses and counterclaims as Seller then has against Buyer.

7.   CLOSING. Preferred Share certificates shall be delivered to Buyer and the
funds therefor shall be delivered to Seller on October 15, 1996 or at such time
to be mutually agreed.

8.   CONDITIONS TO CLOSING

     (i) Buyer understands that Seller's obligation to sell the Preferred Shares
is conditioned upon delivery into escrow or otherwise as agreed between Buyer
and Seller by Buyer of the amount set forth in Section 1 hereof, and to the sale
of a minimum of $5,000,000 of Preferred Shares to the undersigned or other
accredited buyers.

     (ii) Seller understands that Buyer's obligation to purchase the Preferred
Shares is conditioned upon the sale of a minimum of $5,000,000 of Preferred
Shares to the undersigned or other accredited buyers.

     (iii) Seller understands that Buyer's obligation to purchase the Preferred
Shares is conditioned upon delivery of certificate(s) representing the Preferred
Shares as described herein, filing of the Certificate of Designations
substantially in the form of Exhibit A to this Agreement, and provision of an
opinion of counsel confirming the matters set out in Section 3(i), (vii),
(viii), and, to the best of counsel's knowledge, (ix) above.

9.   MISCELLANEOUS.

     (i) This Agreement shall be governed by and interpreted in accordance with
the laws of the Commonwealth of Massachusetts, without reference to choice of
law principles. Facsimile signatures of this Agreement shall be binding on all
parties hereto. All terms used herein that are defined in Regulation S under the
Securities Act shall have the meanings set forth therein.

     (ii) This Agreement may be executed in counterparts, each of which shall be
deemed an original, but all of which together shall constitute one and the same
instrument.

        Re: Restriction on Transfers of Securities


Dear Sirs:

        Selfcare, Inc., a Delaware corporation (the "Company"), proposes to sell
shares ("Shares") of its common stock, $.001 par value per share (the "Common
Stock"), in a public offering (the "Offering") underwritten by underwriters (the
"Underwriters") for whom Lehman Brothers Inc., Dillon, Read & Co. Inc., A.G.
Edwards & Sons and Adams, Harkness & Hill, Inc. are acting as representatives
(the "Representatives") of the several Underwriters.

        The Representatives have indicated that the prospect of sales or other
transfers of Common Stock prior to 120 days after the Offering could undermine
their underwriting effort. Accordingly, the Underwriters have requested that the
undersigned agree not to sell any Common Stock or securities convertible into
or exercisable for Common Stock prior to the expiration of 120 days after the
effective date of the Company's registration statement on Form S-1 (the
"Registration Statement") to be filed by the Company with the Securities and
Exchange Commission in connection with the Offering. The undersigned recognizes
that it is in the best financial interests of the Company and its stockholders
that the Company complete the Offering and that the Underwriters will be
relying on the undersigned's agreement set forth herein.

        The undersigned further recognizes that the undersigned's shares of
Common Stock or securities convertible into or exercisable for Common Stock are
or may be subject to certain restrictions on transferability, including those
imposed by the federal securities laws. Notwithstanding these restrictions, the
undersigned has agreed to enter into this Agreement in order to give further
assurance to the Underwriters that the undersigned's Common Stock will not
enter the public market at a time that might impair the underwriting effort.

        Therefore, the undersigned agrees that the undersigned will not, without
the prior written consent of Lehman Brothers Inc., directly or indirectly,
