ITEM 2.           ACQUISITION OR DISPOSITION OF ASSETS

         On December 31, 1996, Connective Therapeutics, Inc. (the "Company")
acquired the exclusive U.S. and Canadian rights to Ridaura(R) (auranofin), a
disease modifying antirheumatic drug, from SmithKline Beecham Corporation and
related entities ("SmithKline"). Ridaura is an established therapy for
rheumatoid arthritis, an autoimmune disease that afflicts one to two percent of
adult Americans (approximately three million patients), mostly women.

         Under the Asset Purchase Agreement, the Company acquired all rights,
title and interest to the U.S. and Canadian intellectual property rights for
Ridaura, along with related assets such as customer lists, contracts, product
files and unfilled customer orders. As consideration to SmithKline, the Company
provided a $3 million upfront cash payment, an $11.0 million promissory note,
637,733 shares of the Company's common stock, and an obligation to pay up to
$6.0 million in sales-based royalty payments, for an aggregate purchase price of
up to $29.0 million.

         The $3.0 million upfront payment was made from available cash reserves.
The promissory note is payable in two installments in January 1998 and January
1999 (of $6.0 million and $5.0 million, respectively) and is secured by the
intellectual property acquired from SmithKline. The total value of the shares
issued to SmithKline is required to be $9.0 million on December 31, 1997; to
achieve such value, the Company may be obligated to issue additional shares to
SmithKline on such date, or may repurchase a portion of the originally-issued
shares to reduce the market value of the remaining shares to $9.0 million. In
connection with the share issuance, the Company agreed to file in December 1997
a registration statement on Form S-3 covering resale of the shares and to
maintain the registration statement in effect for up to two years.

         Under a related Transitional Services Agreement, customer orders and
distribution for the product will continue to be managed by SmithKline through
1997. SmithKline will receive no additional consideration for performing such
services. The parties also entered into a Supply Agreement, under which
SmithKline will manufacture and supply Ridaura (in final finished package form)
to the Company for an initial term of five years.

non-exclusive right to use any such enhancements or improvements in the

(where Vendor or an Affiliate is the original seller) of products in which

products to any person(s) if Vendor has actual knowledge that such person(s)
intend to resell such products in the Territory.

contingent on net sales. Purchaser makes no representation or warranty regarding
the aggregate amount that may be due as deferred payments.

court, arbitrator or governmental authority having jurisdiction over Vendor, the
Products or the Purchased Assets or of any indenture or other written agreement
to which Vendor may be a party.

         5.3 Title to Purchased Assets. Vendor is the sole owner of all the
Purchased Assets with good title thereto free and clear of any mortgage, lien,
charge, security interest, adverse claim or other encumbrance whatsoever

infringements, threats of infringements or asserted or unasserted claims by
Vendor of infringements or misappropriation of any of the Intellectual Property
in the Territory nor are there any asserted or unasserted claims by

nor does Vendor know of any basis for the existence of any such claim in the
Territory.

Schedules. All Schedules are represented as true, correct and complete except to
the extent specifically addressed in individual representations, warranties and
Schedules.

registration with any court or governmental department, commission, board,
bureau, agency or instrumentality, domestic or foreign, under any applicable
laws, rules or regulations presently in effect, is or will be necessary for, or
in connection with, execution and delivery of the Connective Agreements or the
offer, issuance, sale, execution or delivery by Purchaser of the Promissory
Note, the Equity Agreement or the Connective Shares, or for the performance by
it of its obligations under the Connective Agreements.

Purchaser and each of its directors, officers, employees, advisors, affiliates,
agents and shareholders from and against any and all losses, damages,
liabilities, costs, claims and expenses, including but not limited to attorney's
fees, arising out of, based upon or resulting from:

                  (a) any claims against, or liabilities or obligations of, the
Vendor or against the Purchased Assets other than the Assumed Liabilities;

                  (b) any inaccuracy of any representation or warranty or
schedule of Vendor which is contained in or made pursuant to this Agreement;

                  (c) the non-compliance by Vendor with the provisions of any
applicable bulk sales act governing the purchase and sale of the Purchased
Assets;

                  (d) any tax liability of Vendor (other than sales and use
taxes referred to in Section 3.2 of this Agreement) including, without
limitation, any tax liability arising out of the failure of Vendor or Purchaser
to comply with any provisions of the tax laws of the 

                                      -17-
<PAGE>   18
Commonwealth of Pennsylvania (including, without limitation, provisions
requiring notice to state tax authorities concerning bulk or other sales of
property); or

                  (e) any breach by Vendor of any of its agreements, covenants,
warranties or obligations contained in or made pursuant to this Agreement.

         Vendor shall have no obligation to indemnify Purchaser under this
Section 14.1 for any breach of Vendor's representations and warranties made in
or pursuant to this Agreement, until such time, if any, as the aggregate amount
of the liabilities, losses, damages, claims costs and expenses arising out of
such breach exceeds $50,000 and then only to the extent of such excess.

         14.2 Purchaser's Indemnification. Purchaser will indemnify and hold
harmless Vendor and each of its directors, officers, employees, advisors,
affiliates, agents and shareholders from and against any and all losses,
damages, liabilities, costs, claims and expenses including but not limited to
attorney's fees arising out of, based upon or resulting from:

                  (a) any inaccuracy of any representation or warranty of
Purchaser which is contained in or made pursuant to this Agreement;

                  (b) any breach by Purchaser of any of its agreements,
covenants, warranties or obligations contained in or made pursuant to this
Agreement; or

                  (c) any of the Assumed Liabilities, excluding damages,
liabilities, costs and claims arising out of or related to returns to the extent
that Vendor has retained liability pursuant to Section 9.4.

         Purchaser shall have no obligation to indemnify Vendor under this
Section 14.2 for any breach of Purchaser's representations and warranties made
in or pursuant to this Agreement, until such time, if any, as the aggregate
amount of the liabilities, losses, damages, claims costs and expenses arising
out of such breach exceeds $50,000 and then only to the extent of such excess.
For the avoidance of doubt this limitation does not apply to Purchaser's
obligations to pay any element of the Purchase Price.

         14.3 Claims Procedures. (a) Promptly after the receipt by any party
hereto of notice or upon any party becoming otherwise aware of (x) any claim or
(y) the commencement of any action or proceeding, such party (the "Aggrieved
Party") will, if a claim with respect thereto is to be made against any party
obligated to provide indemnification (the "Indemnifying Party") pursuant to this
Section 14, 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. 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 thirty 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.

                  (b) 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 necessary in the
defense or settlement of such claim or litigation resulting therefrom 

                                      -18-
<PAGE>   19
and to holding the Aggrieved Party harmless from and against any and all losses,
damages and liabilities caused by or arising out of any settlement approved by
the Indemnifying Party or any judgment in connection with 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.

                  (c) 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 Aggrieved Party a sum
equivalent to the total amount demanded in such claim or litigation, or shall
deliver to the Aggrieved Party a surety bond or an irrevocable letter of credit
in form and substance reasonably satisfactory to the Aggrieved Party, 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 reasonable expenses, including, without limitation,
attorneys' fees, incurred by the Aggrieved Party in connection with the defense
against or settlement of such claims 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, including, without limitation,
attorneys' fees, incurred by the Aggrieved Party in the defense against such
claim or litigation.

         14.4 Nature of Survival of Representations, Etc. All representations
and warranties and agreements made by the parties hereto shall survive the Time
of Closing and any investigation at any time made by or on behalf of either
party, provided, however, that no suit or action may be commenced in respect of
a representation or warranty after eighteen (18) months from the Time of
Closing.

Closing Date (as defined in Section 2.2(a)), subject to certain potential
adjustments and other terms and conditions contained herein.

         NOW THEREFORE, the parties hereto agree as follows:

                               ISSUANCE OF SHARES

         2.1      Issuance of Shares. Upon the terms and subject to the
conditions of this Agreement, the Company agrees to issue to SB and SB agrees to
acquire from the Company, the Shares as follows:

                  (a)      Initial Issuance. On the Initial Closing Date, the
Company shall issue to SB shares of Common Stock (the "Initial Issuance Shares")
(the number of which shall be rounded to the nearest whole number) at a price
(the "Initial Price"), each as shall be calculated as follows:

                                    Initial Price =  Two (2) times the average
                                                     daily closing price for the
                                                     Company's Common Stock for
                                                     the twenty (20) trading
                                                     days immediately preceding
                                                     (but not including) the
                                                     third trading day before
                                                     the Initial Closing Date,
                                                     as reported on the NASDAQ
                                                     National Market System.

                                                                 $9,000,000
                                                                 ----------
                                    Initial Issuance Shares  =   Initial Price

                           Such issuance shall be referred to hereinafter as the
"Initial Issuance."

                  (b)      Adjustments on Second Closing Date.

                           (i)      Second Issuance. If on the Second Closing
Date, the aggregate market value of the Initial Issuance Shares is less than
$9,000,000 (based upon the average daily closing price per share for the
Company's Common Stock for the twenty (20) trading days immediately preceding
(but not including) the third trading day before the Second Closing Date, as
reported on the NASDAQ National Market System), then the Company shall issue
that number of additional shares of its Common Stock (the "Second Issuance
Shares") sufficient to bring such aggregate market value of the Shares to
$9,000,000. Such issuance shall be referred to hereinafter as the "Second
Issuance."

                           (ii)     Redemption of Shares. If on the Second
Closing Date, the aggregate market value of the Initial Issuance Shares is
greater than $9,000,000 (based upon the average daily closing price per share
for the Company's Common Stock for the twenty (20) trading days immediately
preceding (but not including) the third trading day before the Second Closing
Date, as reported on the NASDAQ National Market System), then the Company shall
have the right, but not the obligation, to redeem from SB at a price of $0.01
per share that number of the Initial Issuance Shares sufficient to reduce such
aggregate market value of the remaining Initial Issuance Shares to $9,000,000.
In such event, the Company shall deliver to SB at the Second Closing by check or
wire transfer the aggregate redemption price for the excess portion of the
Initial Issuance Shares, and SB will deliver for cancellation the stock
certificate representing the original Initial Issuance Shares (which the Company
will replace as soon as


                                      -3-
<PAGE>   4

practicable thereafter with a stock certificate representing the remaining
portion of the Initial Issuance Shares after the redemption set forth above).

                           (iii)    Other Valuations. In the event that neither
Section 2.1(b)(i) nor Section 2.1(b)(ii) is applicable, then there shall be no
Second Issuance nor any redemption of the Initial Issuance Shares at the Second
Closing.

                  (c)      Approval of the Company's Stockholders. In all events
the sum of the Initial Issuance Shares and the Second Issuance Shares (if any)
shall be not greater than 19.9% of the outstanding Common Stock of the Company
prior to their issuance. In the event that such sum of the Shares is greater
than 19.9% of the outstanding Common Stock of the Company prior to their
issuance, then, at SKB's discretion, (i) the Second Issuance Shares shall be
reduced until such sum of the Shares is equal to 19.9% of the outstanding Common
Stock of the Company, (ii) the issuance of the Second Issuance Shares shall be
subject to, and conditioned upon, approval of the issuance of the Shares by the
Company's Stockholders or (iii) the Second Closing shall be delayed until the
approval of the issuance of the Shares by the Company's Stockholders. In the
event that SB elects to proceed under clause (ii) or (iii) above, and such
stockholder approval is not obtained by December 3, 1998, then the Company shall
be obligated to pay SB in cash the value of the Second Issuance Shares that
would have been issued on the originally-scheduled Second Closing Date but for
this subsection (based upon the average daily closing price per share for the
Company's Common Stock for the twenty (20) trading days immediately preceding
(but not including) the third trading day before the originally-scheduled Second
Closing Date, as reported on the NASDAQ National Market System). Such payment
obligation shall be secured by certain of the assets acquired by the Company
from SB pursuant to a Security Agreement of even date herewith.

         2.2      Closing Dates.

                  (a)      Initial Closing Date. The closing of the acquisition
and issuance of the Initial Issuance Shares (the "Initial Closing") shall be
held at 4:00 p.m. Pacific Standard time on the date (the "Initial Closing Date")
upon which the conditions set forth in Sections 6.1 and 6.2 have been satisfied
or waived, or at such other time or date as the Company and SB may agree in
writing. The parties presently expect that the Initial Closing Date will be the
closing date for the Asset Purchase Agreement, currently scheduled for December
31, 1996.

                  (b)      Second Closing Date. The closing of the issuance of
the Second Issuance Shares or the redemption of the Initial Issuance Shares
pursuant to Section 2.1(b) (the "Second Closing") shall be held at 4:00 p.m.
Pacific Standard time on that date which is twelve (12) calendar months after
the Initial Closing Date (the "Second Closing Date") and which is following the
satisfaction or waiver of the conditions set forth in Sections 6.3 and 6.4, or
at such other time or date as the Company and SB may agree in writing.

                  (c)      Location. The Initial Closing and the Second Closing
shall be held at the offices of SB at One Franklin Plaza, Philadelphia,
Pennsylvania 19102 or at such other place as the Company and SB may agree in
writing.


                                      -4-
<PAGE>   5

                  (d)      Acceleration of Second Closing Date. In the event of
the sale by the Company of all or substantially all of its assets or the
acquisition of the Company by another entity by means of merger or other
transaction as a result of which shareholders of the Company immediately prior
to such acquisition possess a minority of the voting power of the acquiring
entity immediately following such acquisition (an "Acquisition"), then the
Second Closing Date shall be accelerated to a date mutually acceptable to the
Company and SB, which date in no event shall be later than one (1) day prior to
the closing of such Acquisition.

         2.3      Delivery. Subject to the terms and conditions of this
Agreement, at the Initial Closing and the Second Closing, as the case may be, or
as soon as practicable thereafter, the Company will deliver to SB stock
certificates representing the number of Shares subject to issuance hereunder.
One (1) business day prior to the Initial Closing Date, the Company shall
provide SB with a letter from the Chief Financial Officer of the Company
specifying the calculation of the Initial Price and the number of Initial
Issuance Shares to be issued at the Initial Closing. One (1) business day prior
to the Second Closing Date, the Company shall provide SB with a letter from the
Chief Financial Officer of the Company specifying the calculation of the number
of Second Issuance Shares (if any) to be issued at the Second Closing, the
number of Initial Issuance Shares (if any) to be redeemed at the Second Closing,
or the fact that no issuance or redemption will occur at the Second Closing
pursuant to Section 2.1(b)(iii).

         2.4      Restriction on Transfer. SB hereby agrees that, without the
prior written consent of the Company, it will not, during the period commencing
on the Initial Closing Date and ending on the Second Closing Date, (1) offer,
pledge, sell, contract to sell, sell any option or contract to purchase,
purchase any option or contract to sell, grant any option, right or warrant to
purchase, or otherwise transfer or dispose of, directly or indirectly, any
Shares or (2) enter into any swap or other arrangement that transfers to
another, in whole or in part, any of the economic consequences of ownership of
the Shares, whether any such transaction described in clause (1) or (2) above is
to be settled by delivery of the Shares or such other securities, in cash or
otherwise.

                                    ARTICLE 3

                     REGISTRATION RIGHTS AND SALE OF SHARES

         3.1      Form S-3 Registration. Unless otherwise requested by SB, the
Company will use its best efforts to prepare and file (and on or before the
Second Closing Date, effect) a registration statement on Form S-3 that
contemplates a distribution of securities on a delayed or continuous basis
pursuant to Rule 415 under the 1933 Act and any related qualification or
compliance with respect to all of the Registrable Securities; provided, however,
that the Company shall not be obligated to effect any such registration,
qualification or compliance: (1) if Form S-3 is not available for such offering
by SB other than by reason of the Company's action or inaction; or (2) if the
Company shall furnish to SB a certificate signed by the President of the Company
stating that in the good faith judgment of the Company, it would be seriously
detrimental to the Company and its stockholders for such Form S-3 Registration
to be effected at such time, in which event the Company shall have the right to
defer the filing or effectiveness of the Form S-3 registration statement for a
period of time deemed necessary by the Company, but in any event not to exceed
ninety (90) days.


                                      -5-
<PAGE>   6

         3.2      Obligations of the Company. When required under this Article 3
to effect the registration of the Registrable Securities, the Company shall, as
expeditiously as reasonably possible:

                  (a)      Use its best efforts to cause such registration
statement to become effective on or before the Second Closing Date, and, upon
the request of SB, keep such registration statement effective for up to two (2)
years and update such registration statement during such two-year period;
provided, however, if the Company shall furnish to SB a certificate signed by
the President of the Company stating that in the good faith judgment of the
Company, it would be seriously detrimental to the Company and its stockholders
for such registration statement to remain effective, the Company shall have the
right to suspend the effectiveness of the registration statement for a period of
time deemed necessary by the Company, but in any event not to exceed ninety (90)
days.

                  (b)      Furnish to SB such numbers of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
1933 Act, and such other documents as it may reasonably request in order to
facilitate the disposition of Registrable Securities.

                  (c)      Use its best efforts to register and qualify the
securities covered by such registration statement under such other securities or
Blue Sky laws of such jurisdictions as shall be reasonably requested by SB,
provided that the Company shall not be required in connection therewith or as a
condition thereto to qualify to do business or to file a general consent to
service of process in any such states or jurisdictions.

         3.3      Furnish Information. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to this Article 3 with
respect to the Registrable Securities that SB shall furnish to the Company such
information regarding itself, the Registrable Securities held by it, and the
intended method of disposition of such securities as shall be required to effect
the registration of the Registrable Securities.

         3.4      Expenses of Registration. All expenses other than underwriting
discounts and commissions incurred in connection with registrations, filings or
qualifications pursuant to this Article 3, including (without limitation) all
registration, filing and qualification fees, printers' and accounting fees, fees
and disbursements of counsel for the Company, and the reasonable fees and
disbursements of one counsel for SB shall be borne by the Company.

         3.5      Limitation on Sale of Shares. SB will notify the Company at
least two trading days in advance of any proposed sale or other transfer of any
Registrable Securities. SB and the Company agree and acknowledge that it is in
their mutual interest that disposition of the Registrable Securities be
accomplished in a manner that does not disrupt or undermine the trading market
for the Company's common stock on the NASDAQ National Market System, and the
parties will work together to explore methods of disposition in order to achieve
such goal. SB will also consider in good faith any request by the Company to
delay such sale or transfer for a reasonable time or to arrange such sale or
transfer through an underwriter or market maker approved by the Company.

         3.6      Indemnification. In the event any Registrable Securities are
included in a registration statement under this Article 3:

                  (a)      To the extent permitted by law, the Company will
indemnify and hold harmless SB, any underwriter (as defined in the 1933 Act) for
SB and each person, if any, who controls SB or such underwriter within the
meaning of the 1933 Act or the 1934 Act, against any losses, claims, damages, or
liabilities (joint or several) to which they may become subject under the 1933
Act, the 1934 Act or other federal or state law, insofar as such losses, claims,
damages, or liabilities (or actions in respect thereof) arise out of or are
based upon any of the following statements, omissions or violations
(collectively a "Violation"): (i) any untrue statement or alleged untrue
statement of a material fact contained in such registration statement, including
any preliminary prospectus or final prospectus contained therein or any
amendments or supplements thereto, (ii) the omission or alleged omission to
state therein a material fact required to be stated therein, or necessary to
make the statements therein not misleading, or (iii) any violation or alleged
violation by the Company of the 1933 Act, the 1934 Act, any state securities law
or any rule or regulation promulgated under the 1933 Act, the 1934 Act or any
state securities law; and the Company will pay to SB and each such underwriter
or controlling person, as incurred, any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such loss,
claim, damage, liability, or action; provided, however, that the indemnity
agreement contained in this subsection 3.6(a) shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability, or action if such
settlement is effected without the consent of the Company (which consent shall
not be unreasonably withheld), nor shall the Company be liable in any such case
for any such loss, claim, damage, liability, or action to the extent that it
arises out of or is based upon a Violation which occurs in reliance upon and in
conformity with written information furnished expressly for use in connection
with such registration by SB or any such underwriter or controlling person.

                  (b)      To the extent permitted by law, SB will indemnify and
hold harmless the Company, each of its directors, each of its officers who has
signed the registration statement, each person, if any, who controls the Company
within the meaning of the 1933 Act, any underwriter, any other person selling
securities in such registration statement and any controlling person of any such
underwriter or other person, against any losses, claims, damages, or liabilities
(joint or several) to which any of the foregoing persons may become subject,
under the 1933 Act, the 1934 Act or other federal or state law, insofar as such
losses, claims, damages, or liabilities (or actions in respect thereto) arise
out of or are based upon any Violation, in each case to the extent (and only to
the extent) that such Violation occurs in reliance upon and in conformity with
written information furnished by SB expressly for use in connection with such
registration; and SB will pay, as incurred, any legal or other expenses
reasonably incurred by any person intended to be indemnified pursuant to this
subsection 3.6(b), in connection with investigating or defending any such loss,
claim, damage, liability, or action; provided, however, that the indemnity
agreement contained in this subsection 3.6(b) shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of SB, which consent shall not be
unreasonably withheld. Notwithstanding the foregoing, in no event shall SB's
total indemnification obligation exceed the aggregate amounts SB has received
from the sale of the Shares pursuant to the registration statement filed under
this Article 3.

                  (c)      Promptly after receipt by an indemnified party under
this Section 3.6 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 3.6, deliver to
the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party
(together with all other indemnified parties which may be represented without
conflict by one counsel) shall have the right to retain one separate counsel,
with the reasonable fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action, if prejudicial to its ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under this Section
3.6, but the omission so to deliver written notice to the indemnifying party
will not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 3.6.

                  (d)      If the indemnification provided for in this Section
3.6 is held by a court of competent jurisdiction to be unavailable to an
indemnified party with respect to any loss, liability, claim, damage, or expense
referred to therein, then the indemnifying party, in lieu of indemnifying such
indemnified party hereunder, shall contribute to the amount paid or payable by
such indemnified party as a result of such loss, liability, claim, damage, or
expense in such proportion as is appropriate to reflect the relative fault of
the indemnifying party on the one hand and of the indemnified party on the other
in connection with the statements or omissions that resulted in such loss,
liability, claim, damage, or expense as well as any other relevant equitable
considerations. The relative fault of the indemnifying party and of the
indemnified party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the
indemnifying party or by the indemnified party and the parties' relative intent,
knowledge, access to information, and opportunity to correct or prevent such
statement or omission.

                  (e)      Notwithstanding the foregoing, to the extent that the
provisions on indemnification and contribution contained in the underwriting
agreement entered into in connection with the underwritten public offering are
in conflict with the foregoing provisions, the provisions in the underwriting
agreement shall control.

                  (f)      The obligations of the Company and SB under this
Section 3.6 shall survive the completion of any offering of Registrable
Securities in a registration statement under this Article 3, and otherwise.

         3.7      Assignment of Registration Rights. The rights to cause the
Company to register Registrable Securities pursuant to this Article 3 may not be
assigned by SB without the Company's prior written consent. Any such assignment
consented to by the Company shall be


                                      -8-
<PAGE>   9

effective only if immediately following such transfer the further disposition of
such securities by the transferee or assignee is restricted under the 1933 Act.

         3.8      Termination of Registration Rights. SB shall not be entitled
to exercise any right provided for in this Article 3, and the Company shall have
no further obligations under this Article 3, after such time as Rule 144 or
another similar exemption under the 1933 Act is available for the sale of all of
SKB's shares during a three (3) month period without registration.

                                    ARTICLE 4

         5.2      Purchase of Shares for Investment. SB acknowledges that the
Shares have not been registered under the 1933 Act or any state securities laws
and that the Company has no present intention of registering the Shares, except
as provided in Article 3 hereof. SB represents and warrants that it is acquiring
the Shares for investment purposes only, and not as a nominee or agent, and not

Agreement so long as (a) such disclosure is necessary for the evaluation and
consummation of the transactions contemplated by this Agreement and the Asset
Purchase Agreement and (b) such Persons are informed by SB of the confidential
nature of such information and are bound in writing by SB to treat such
information confidentially. SB and its Affiliates shall exercise at least the

<PAGE>   17

                  (ii)     by either the Company or SB if the Initial Closing
shall not have been consummated on or before January 31, 1997;

                  (iii)    by either the Company or SB if there shall be any law
or regulation that makes consummation of the transactions contemplated hereby
illegal or otherwise prohibited or if consummation of the transactions
contemplated hereby would violate any nonappealable final order, decree or
judgment of any court or governmental body having competent jurisdiction; or

                  (iv)     by the Company or by SB, if there has been a material
misrepresentation or breach of warranty on the part of SB (in the case of
termination by the Company) or by the Company (in the case of termination by SB)
in the representations and warranties contained herein; or any condition to such
party's obligations hereunder becomes incapable of fulfillment through no fault
of such party and is not waived by such party;

provided that the party against whom termination is sought shall be afforded the
opportunity to cure any defect until such Initial Closing Date or Second Closing
Date, as the case may be. The party desiring to terminate this Agreement shall
give notice of such termination to the other party.

         11.2     Effect of Termination. If this Agreement is terminated as
permitted by Section 11.1, termination shall be without liability of either
party (or any stockholder, director, officer, employee, agent, consultant or
representative of such party) to the other party to this Agreement; provided
that if such termination shall result from the willful failure of either party
to fulfill a condition to the performance of the obligations of the other party,
failure to perform a covenant of this Agreement or breach by either party hereto
of any representation or warranty or agreement contained herein, such party
shall be fully liable for any and all damages incurred or suffered by the other
party as a result of such failure or breach. Any dispute regarding the foregoing
shall be resolved pursuant to Section 12.8 hereto. The provisions of Section 8.1
shall survive any termination hereof pursuant to Section 11.1 or otherwise.

                             SECURED PROMISSORY NOTE


December 31, 1996                                               U.S. $11,000,000

         FOR VALUE RECEIVED, the undersigned, CONNECTIVE THERAPEUTICS, INC., a
Delaware corporation ("Maker"), HEREBY PROMISES TO PAY to the order of
SMITHKLINE BEECHAM CORPORATION, a Pennsylvania corporation or its assigns
("Payee"), upon the Payment Dates (as defined below), the aggregate sum of
Eleven Million Dollars ($11,000,000) in lawful money of the United States.

         1.       Capitalized terms used herein and not otherwise defined herein
shall have the meanings ascribed to such terms in the Asset Purchase Agreement
dated December 2, 1996 between Payee, Maker and the other parties named therein.

         2.       Maker promises to make payment under this Note on the
following dates (each a "Payment Date"):

<TABLE>
<S>                                 <C>       
                  January 7, 1998   $6,000,000
                  January 7, 1999   $5,000,000
</TABLE>


         3.       This Note is secured by the Intellectual Property (as defined
in Section 1.1(f) of the Asset Purchase Agreement) in accordance with a separate
security agreement (the "Security Agreement") between Maker and Payee being
entered into as of the date hereof to be executed simultaneously with the
execution of this Note. Payee has all rights of a secured creditor under
California law.

         4.       Maker will be deemed to be in default hereunder and the unpaid
balance of this Note will become immediately due and payable upon (a) any
failure to make the payments required under Section 2 of this Note within thirty
(30) days of the date payment is due or (b) any material breach of the Security
Agreement.

         5.       Maker has the right to prepay all or any part of this Note,
without any penalty or premium of any kind. Any prepayments shall be applied to
reduce the next payment due.

         6.       The indebtedness evidenced by this Note shall be subordinate
and junior in right of payment, to the extent and in the manner provided below,
but only to the extent requested by the holders of the Senior Indebtedness (as
defined below), to the prior payment in full of all Senior Indebtedness;
provided, that the Payee's security interest in the Intellectual Property shall
be senior to any security interest held by the holders of Senior Indebtedness.

                  (a)      Maker shall not be obligated to make, and Payee shall
not be entitled to demand or receive, except as provided in this Section 6, any
payment on account of this Note if,

<PAGE>   2

at the time of such proposed payment, (i) any amount in respect of the Senior
Indebtedness shall be due and payable or (ii) any default in respect of any
Senior Indebtedness shall have occurred and be continuing, unless within 120
days after the occurrence of such default, the maturity of such Senior
Indebtedness shall not have been accelerated.

         (b)      In the event of any dissolution, winding-up, liquidation or
reorganization of Maker, whether voluntary or involuntary, in bankruptcy,
insolvency, receivership or other proceedings, upon an assignment for the
benefit of creditors or otherwise, (i) all principal of, interest on and other
amounts payable in respect of the Senior Indebtedness shall be paid in full
before Payee shall be entitled to receive any further payment or distribution in
respect of this Note, and (ii) any payment or distribution of any kind to which
Payee would be entitled except for the provisions of this paragraph (b) shall be
paid or delivered by Maker, or by Payee if received by Payee, directly to the
holders of the Senior Indebtedness or their respective representatives (pro rata
on the basis of the respective amounts of the Senior Indebtedness held by such
holders) for application to the payment of the Senior Indebtedness until the
Senior Indebtedness shall have been paid in full.

         (c)      In any proceeding referred to in paragraph (b) above which is
commenced by or against Maker, the holders of the Senior Indebtedness may, and
are hereby irrevocably authorized and empowered to, demand, sue for, collect and
receive every payment or distribution referred to in paragraph (b) above and
take such other action as the holders of the Senior Indebtedness may deem
necessary or advisable for the exercise or enforcement of any of their rights or
interests in respect of this Note.

         (d)      In the event that Payee receives any payment or distribution
of any kind or any security in respect of this Note in contravention of any of
the terms hereof, such payment, distribution or security shall be received in
trust for the benefit of the holders of the Senior Indebtedness and shall
promptly be paid over or delivered in the same form as so received to the
holders of the Senior Indebtedness for application to the payment of the Senior
Indebtedness until the Senior Indebtedness or the current installments thereof,
as may be applicable, shall have been paid in full.

         (e)      Nothing contained herein shall impair, as between Maker or its
creditors, other than the holders of the Senior Indebtedness and Payee, the
obligation of Maker to pay to Payee the amounts owed under this Note as and when
due and payable in accordance with the terms hereof, or prevent Payee, upon
default with respect to this Note, from exercising all rights, powers and
remedies otherwise provided herein or by applicable law, all subject to the
rights of the holders of Senior Indebtedness hereunder.

         (g)      "Senior Indebtedness" shall mean, as at the date of
determination thereof, all indebtedness of Maker outstanding on the date hereof,
which is secured by all or substantially all of the Company's intellectual
property. After Maker has made the $6,000,000 payment under Section 2.1 above,
Payee agrees to consider in good faith any request by Maker to amend this Note
to allow future secured indebtedness of Maker to be included in the foregoing
definition of "Senior Indebtedness."

         7.       Maker hereby waives demand, presentment for payment, notice of
dishonor, protest and notice of protest.

         8.       This Note may not be changed orally, but only by an agreement
in writing and signed by the party against whom enforcement of any waiver,
change, modification or discharge is sought.

         9.       THIS NOTE SHALL BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF CALIFORNIA APPLICABLE TO CONTRACTS
WHOLLY MADE AND PERFORMED IN THE STATE OF CALIFORNIA. Whenever possible each
provision of this Note shall be interpreted in such manner as to be effective
and valid under applicable, law, but if any provision of this Note shall be
prohibited by or invalid under applicable law, such provision shall be
ineffective to the extent of such prohibition or invalidity, without
invalidating the remainder of such provision or the remaining provisions of this
Note.

                               SECURITY AGREEMENT


         This SECURITY AGREEMENT dated as of December 31, 1996 (the "AGREEMENT")
is entered into between CONNECTIVE THERAPEUTICS, INC., a Delaware corporation
("DEBTOR") and SMITHKLINE BEECHAM CORPORATION, a Pennsylvania corporation
("SECURED PARTY"). For purposes of this Agreement, the term "SECURED PARTY"
includes any subsequent holder of the Note (as defined below).

                                    RECITALS:

         A.       Debtor and Secured Party are parties to that certain Asset
Purchase Agreement dated as of December 2, 1996 (the "ASSET PURCHASE AGREEMENT")
between Debtor, Secured Party and certain other parties, pursuant to which
Debtor has purchased certain assets from the Secured Party;

         B.       Part of the purchase price therefore will be paid by delivery
by Debtor of a Secured Promissory Note dated the date hereof (the "NOTE") in an
aggregate amount of $11,000,000;

         C.       Another part of the purchase price therefore will be paid
pursuant to Section 4.2 of the Asset Purchase Agreement in an aggregate amount
of up to $6,000,000, contingent upon Debtor's net sales of certain products (the
"Deferred Payments");

         D.       Subject to the occurrence of certain events, another part of
the purchase price theretofore may be paid in cash (the "Equity Payout")
pursuant to Section 2.1(c) of that certain Stock Issuance Agreement of even date
herewith between Debtor and SmithKline Beecham Properties, Inc., an affiliate of
Secured Party (the "Stock Agreement");

         E.       The parties intend that Debtor's obligations to repay the Note
and its contingent obligations to make the Deferred Payments and the Equity
Payout be secured by certain of the assets purchased by Debtor from Secured
Party.

         NOW, THEREFORE, in consideration of the mutual promises contained
herein, and as an inducement to Secured Party to lend Debtor the amounts
reflected by the Note and to enter into the Asset Purchase Agreement, the
parties hereto agree as follows:

         1.       Creation of a Security Interest. As security for payment of
the Indebtedness (as defined below) of Debtor to Secured Party when and as due,
Debtor hereby grants Secured Party a security interest in the collateral
described in Section 2 below (the "COLLATERAL"). For purposes of this Agreement,
"INDEBTEDNESS" shall mean the Equity Payout, the Deferred Payments and all
obligations and liabilities of Debtor to Secured Party under this Agreement and
the Note in the amount of $11,000,000, including any extensions, modifications
or renewals thereof. The security interest granted hereby shall be and remain a
first and prior security interest in all of the Collateral.

<PAGE>   2

         2.       Collateral. The Collateral that is subject to the security
interest created hereby consists of all of Debtor's right, title and interest in
and to the Intellectual Property (as defined in Section 1.1(f) of the Asset
Purchase Agreement), purchased by Debtor from Secured Party pursuant to the
Asset Purchase Agreement.

         3.       Debtor's Obligation. Debtor shall pay to Secured Party all
amounts due and owing to Secured Party under the Note, Section 4.2 of the Asset
Purchase Agreement and pursuant to the Equity Payout, in accordance with the
terms of same, when, if and as the same become due.

         4.       Protection of the Collateral. Until such time as the Note has
been paid in full, Debtor shall not create any lien or encumbrance on the
Collateral, except for liens that are subordinated to Secured Party's security
interest in the Collateral in a manner reasonably satisfactory to Secured Party.

         5.       Default. Each of the following events shall be defined as an
"EVENT OF DEFAULT" hereunder:

                  (a)      Debtor fails to pay any sum due under the
Indebtedness in accordance with the terms hereof, if such nonpayment continues
for thirty (30) days after the date such sum is due;

                  (b)      Debtor files any petition or action for relief under
any bankruptcy, reorganization, insolvency or moratorium law, or any other law
for the relief of, or relating to, debtors, now or hereafter in effect, or makes
any assignment for the benefit of creditors, or takes any corporate action in
furtherance of any of the foregoing;

                  (c)      An involuntary petition is filed against Debtor
(unless such petition is dismissed or discharged within ninety (90) days), under
any bankruptcy statute now or hereafter in effect, or a custodian, receiver,
trustee, assignee for the benefit of creditors (or other similar official) is
appointed to take possession, custody, or control of any property of Debtor;

                  (d)      Debtor breaches, or defaults under any material term,
condition or provision contained in this Agreement or the Note not specifically
referred to in this Section 5, if such breach or default continues for thirty
(30) days after receipt of notice from Secured Party; or

                  (e)      Debtor shall (i) default in any payment or payments
on any Senior Indebtedness (as defined in the Note), beyond the period of grace,
if any, provided in the instrument or agreement under which such Senior
Indebtedness was created or (ii) default in the performance of any agreement or
condition relating to any Senior Indebtedness, or any other event shall occur or
condition exist (and continue beyond the applicable grace period, if any), the
effect of which is to cause, or to permit the holders of such Senior
Indebtedness to cause, such Senior Indebtedness to become due prior to its
stated maturity.

         6.       Rights of Secured Party.

                  (a)      Upon the occurrence of any Event of Default, Secured
Party shall be entitled to declare any Indebtedness secured hereby immediately
due and payable without notice of default, presentment or demand for payment,
protest or notice of nonpayment or dishonor, or other notices or demands of any
kind or character. In addition to the right of acceleration granted herein, and
all other rights of Secured Party, Secured Party shall be entitled to any and
all remedies available under the Uniform Commercial Code in force in the State
of California as of the date of the event of Default.

                  (b)      Secured Party shall give Debtor notice of the time on
or after which any sale or other intended disposition of the Collateral is to be
consummated, which notice shall be mailed, by first class mail, postage prepaid,
to Debtor in the manner set forth in Section 10(b) hereof at least thirty (30)
days prior to the time of such sale or other intended disposition. Secured Party
shall promptly provide a copy of such notice to all holders of Senior
Indebtedness known to Secured Party, including without limitation Silicon Valley
Bank and MMC/GATX Partnership No. 1.

                  (c)      Each purchaser at any sale of the Collateral shall
hold the property sold free from any claim or right on the part of Debtor. Any
public or private sale of the Collateral or any part of it shall be held at such
time or times within ordinary business hours and at such place or places as
Secured Party may reasonably fix in the notice of sale, and at any such sale the
Collateral, or the portion thereof to be sold, may be sold as an entirety or in
separate parts, as Secured may reasonably determine. If permitted by law, Debtor
or Secured Party may bid (which Secured Party bid may be, in whole or in part,
in the form of cancellation of indebtedness) for the purchase of the Collateral.

         7.       Application of the Proceeds. All proceeds of any sale of the
Collateral by Secured Party pursuant to Section 6 shall be applied as follows:

under this Agreement and as are appropriate for companies of like size, taking
into account the scope of activities contemplated herein. BUYER shall, at the

                        ARTICLE 4 - TERM AND TERMINATION

     4.1  This Agreement shall have an initial term of five (5) years commencing

Agreement
                           
     4.2  Either party may terminate this Agreement by giving sixty (60) days
notice to the other party if the other party is in material breach of any term
of this Agreement and fails to cure that breach within such sixty (60) day
period.

     4.3  This Agreement may be canceled upon thirty (30) days' prior written
notice by either party at any time during this Agreement if the other party

or of its assets; or if any other party proposes a written agreement of
composition for extension of its debts; or if the other party shall be served
with an involuntary petition against it, filed in any insolvency proceeding, and
such petition shall not be dismissed within sixty (60) days after filing
thereof; or if the other party shall be a party to any dissolution or
liquidation, or if the other party shall make a general assignment for the
benefit of its creditors; or if the other party is subject to any final order of
debarment which can be expected to have a material adverse effect on the sales
of the Product.

      4.4  Upon termination, SB will deliver and BUYER shall promptly pay SB for
all inventory of Products, raw materials, components and works in progress
together with copies of records relating to the NDA and to the manufacture of
Product that have not already been provided pursuant to the Asset Purchase
Agreement.

                           ARTICLE 5 - CONFIDENTIALITY

      5.1  SB shall use the same efforts to maintain the confidentiality of any
proprietary or confidential information regarding the manufacture or sale of the
Products as SB uses with respect to its own prescription pharmaceutical
products; provided, however, that any such confidential or proprietary
information (a) may be used by SB in performing its obligations under the Supply
Agreement, (b) may be shared, subject to execution of a confidentiality
agreement, with potential third party manufacturers of the Products and (c) may
be disclosed, subject to execution of a confidentiality agreement, with
potential purchasers of rights outside the Territory to product lines for which
auranofin is an active ingredient; provided that no information specific to
Purchaser shall be disclosed in such context.

      5.2  SB's obligations hereunder shall not apply to information which: (i)
is already in the public domain at the time of disclosure; (ii) becomes part of
the public domain through no action or omission of SB after disclosure to the
receiving party; (iii) has been or is disclosed to SB in good faith by a third
party who was or is not, at the time of disclosure, under any obligation of
confidence to BUYER at the time the third party disclosed such information; or
(v) is required to be disclosed by law.

      5.3  This Article 5 shall survive expiration or termination of this
Agreement for a period of ten (10) years.
         
                            ARTICLE 6 - MISCELLANEOUS

      6.1  Corporate Organization and Authority. Each party represents and

standing under the laws of the jurisdiction wherein it is organized, and that it
has all necessary power and authorization to assume the obligations under this
Agreement, and to discharge them pursuant to the terms hereof.

      6.2  Public Announcements.

      The parties hereto agree that no disclosure or public announcement with
respect to this Agreement or any of the transactions contemplated by this
Agreement shall be made by any party hereto without the prior written consent of
SB or Buyer provided, however, that nothing herein contained shall restrict SB
or BUYER from making any public announcement of the transactions contemplated by
this Agreement to the extent that it, in its sole discretion reasonably
exercised, is of the view that such announcement is required or deemed advisable
in order to meet its obligations under the securities laws or stock exchange
requirements in the United Kingdom or the United States of America; provided
further that prior to making such announcement, the party making it shall
provide particulars thereof in writing to the other party. Notwithstanding the
foregoing, BUYER may disclose this Agreement and the transactions contemplated
hereby, to the extent reasonably necessary, in connection with (a) a private
placement of securities for the purpose of obtaining the financing necessary to
pay the Purchase Price (as defined in the Asset Asset Purchase Agreement) and
the fees and expenses related to the Asset Purchase Agreement, the transactions
contemplated thereby and such financing, (b) BUYER's filing and disclosure
obligations under the Securities Act of 1934, as amended, including the filing
of the Asset Purchase Agreement and all exhibits with the Securities and
Exchange Commission, and/or (c) any registration of one or more of the Products
with any state or Federal agency.

      6.3  Force Majeure. Neither party shall be liable to the other if, and to
the extent, that the performance or delay in performance of any of its
obligations under this Agreement is prevented, restricted, delayed or interfered
with due to circumstances beyond the reasonable control of such party,
including, but not limited to, government legislation, fires, floods,
explosions, epidemics, accidents, acts of God, wars, riots, strikes, lockouts or
other concerted acts of workers and/or acts of government. The party claiming an
event of force majeure shall promptly notify the other party in writing, and
provide full particulars of the cause or event and the date of first occurrence
thereof, as soon as possible after the event and also keep the other party
informed of any further developments. The party so affected shall use its best
efforts to remove the cause of non-performance, and both the parties shall
resume performance hereunder with the utmost dispatch when such cause is removed
unless this Agreement is previously expired or terminated under Article 4
hereof.

      6.4  Amendment and Waiver. This Agreement may be amended only by a writing
which specifically states that such an amendment is its purpose and which is
signed by both parties. No course of dealing between the parties or failure by
either party to exercise any right or remedy hereunder shall constitute an
amendment to this Agreement or a waiver of any other right or remedy or the
later exercise of any right or remedy.

      6.5  Governing Law. This Agreement shall be governed by and construed in
accordance with the substantive law of the Commonwealth of Pennsylvania without
regard to its rules for conflicts of law.

      6.6  Successors and Assigns. The provisions of this Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective
successors and assigns; provided, however, that no party may assign, delegate or
otherwise transfer any of its rights or obligations


                                      -10-
<PAGE>   11
under this Agreement without first receiving the prior written consent of the
other party hereto which consent shall not be unreasonably withheld, except that
either party may assign and delegate its rights and duties hereunder without
obtaining such consent (i) to any Affiliate or subsidiary of such party, or (ii)
to any party or entity which acquires substantially all of the business or
assets of such party if such party guarantees the performance of the acquiring
party and the acquiring party expressly assumes the assigning party's
obligations hereunder.

      6.7  Nature of Agreement. In operating under the Agreement, each party
shall act independently and this Agreement shall not be construed as creating
any partnership, joint venture or incorporated business entity. Neither party
shall have any authority to incur any liability or obligation whatsoever on
behalf of the other.

                                                CONFIDENTIAL TREATMENT REQUESTED



                         TRANSITIONAL SERVICES AGREEMENT


         AGREEMENT, dated as of December 31, 1996, between SmithKline Beecham
Corporation, a Pennsylvania corporation ("SB") and Connective Therapeutics Inc.,
a Delaware corporation ("Connective").

         WHEREAS, SB and Connective have entered into an Asset Purchase
Agreement dated December 2, 1996 (the "Purchase Agreement"), pursuant to which
Connective has acquired certain products listed on EXHIBIT A (the "Products");

         WHEREAS, in connection with such acquisition Connective desires SB to
continue to provide certain services with respect to the Products, and SB is
willing to continue to provide such services for the benefit of Connective;

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants herein contained and intending to be legally bound, the parties hereby
agree as follows:

                                    SECTION 1
                       ORDER ENTRY, SHIPPING AND INVOICING

         1.1 Services. During the period beginning January 7, 1997 and ending
December 31, 1997 or such earlier date as Connective may reasonably request (the
"Period"), SB shall perform order entry, packaging, shipping, invoicing and
credit and collection services for the Products. SB also agrees not to remove
the Products from its price list prior to the end of the Period; thereafter SB
shall remove the Products from its price list as soon as practical. All such
services shall be performed on a timely basis consistent with SB's practices in
effect immediately prior to the date of this Agreement.

         1.2 Payments. SB shall receive no separate consideration for the
provision of services hereunder other than as set forth in the Purchase
Agreement. No later than the 30th day following the last day of each calendar
quarter (or the last day of the Period if the Period does not conclude at the
end of a calendar quarter) during the Period (each a "Collection Period"), SB
shall pay Connective an amount equal to the net sales (computed on the basis set
forth in EXHIBIT B) of the Products for such Collection Period less [*] percent
([*]%) of such net sales for cash discounts (to the extent that SB has given
such discounts); provided that during the period from the date of this Agreement
through February 28, 1997 SB shall pay Connective on the basis of gross sales
(computed on the basis set forth in EXHIBIT B) rather than net sales, again
subject to applicable cash discounts. SB shall fulfill orders from its existing
inventory of Products until such inventory is exhausted and the cost of such
Products shall be deducted (at [*] per bottle of 60 capsules) from the related
net sales.

*        Confidential treatment has been requested for the language which has
         been omitted. All such omitted material has been filed separately with
         the SEC.
<PAGE>   2
         1.3 Supporting Statements. Each payment made pursuant to Section 1.2
shall be accompanied by a statement setting forth gross sales and all
information used to calculate the payment made to Connective, together with a
certificate signed by the Director, Finance and Planning, SmithKline Beecham
Pharmaceuticals division of SB, that such statement complies with this
Agreement. SB shall permit Connective's independent auditors to have access to
SB's records and work papers as may be necessary to verify the accuracy of the
statements provided to Connective hereunder and to assure that SB has complied
with the terms of this Agreement. Bad debts incurred in connection with sales of
the Products after the date hereof will be at the expense of Connective. During
the Period the bad debt expense for any account shall be apportioned between the
Products and other SB products sold to the same customer pro rata based on total
amounts due. Connective shall have no right to separately pursue collections
directly from customers of any amounts due with respect to bad debts for sales
during the Period.

         1.4 Sales Information. On the second business day after each calendar
month, SB shall provide Connective (in a format reasonably acceptable to
Connective) quantities of Products sold and related sales dollars (itemized by
customer and/or distributor), cost of Products sold, inventory of Products as of
the end of the Collection Period and any other information reasonably requested
in advance by Connective.

                                    SECTION 2
                            NOTIFICATION TO THE TRADE

         During the Period SB shall (a) notify all customers of the transfer of
the Products to Connective and make available a duplicate set of mailing labels
for wholesalers for Connective's use and (b) print a brief notice concerning the
sale of the Products to Connective on appropriate invoices after the date of the
Purchase Agreement.

                                    SECTION 3
                               GENERAL PROVISIONS

         3.1 Independent Contractors. SB is an independent contractor in
providing services with respect to the Products.

         3.2 Confidentiality. The confidentiality obligations set forth in
Sections 6.5 and 8.4 of the Purchase Agreement shall apply to any proprietary or
confidential information provided by either party to the other party in
connection with this Agreement.

         3.3 Indemnification. SB agrees to indemnify, defend and hold Connective
harmless from and against any and all claims, liabilities, damages, losses,
costs and expenses (including reasonable attorney fees), from any third party
claims or suits brought against Connective which arise out of the negligence or
willful misconduct of SB or one of its employees in performing the services
under this Agreement. The procedures for indemnification shall be the same as
provided in Section 14.3 of the Purchase Agreement.

                               Gross and Net Sales

Gross and Net Sales are reported according to generally accepted accounting
practices by SB in the ordinary course of its business.

Gross Sales

Gross Sales is defined as the recording of Revenue with associated Accounts
Receivable for accounting purposes for specific shipment/invoicing transactions.
Invoices are prepared immediately following notification of shipment of goods.

Invoices are dated as the same day of shipment and reflect the number of units
shipped multiplied by the Unit price, which in most cases is WAC (Wholesale
Acquisition Cost). Gross Sales is recorded to the general ledger monthly from
the SB Month-to-Date Sales Report. Quarterly summarization of Gross Sales for
Connective will be in accordance with the SB Finance calendar. This calendar is
based upon a 13 week quarter comprised of 4 weeks, 4 weeks and 5 weeks for each
quarter.

Net Sales

Net Sales is defined as Gross Sales less allowable adjustments. Adjustments
include product returns, Medicaid reimbursements, chargebacks, rebates, state
payments, admin. fees and any other contractual reimbursement but do not include
cash discounts.
