               2.1  Term of Partnershiphip.

                    (a) The term of the  Partnership  (the  "Partnership  Term")
shall  commence  upon the filing  with the office of  Secretary  of State of the
State of Delaware of the  Certificate of Limited  Partnership of the Partnership
and shall continue until  expiration of the Term (as defined in Section 5 of the

4.1), without giving effect to any Extended Term pursuant to Section 8(C) of the
Sales Agency  Agreement.  If the  Partnership  Term  terminates  for any reason,
whether or not under this Paragraph  2.1(a),  the business and management of the
Partnership  shall continue on the terms of this Agreement until the Partnership
is dissolved  pursuant to Article VIII of this  Agreement.  A Partner  shall not
attempt to  terminate  this  Agreement  or dissolve  the  Partnership  except as
contemplated in this Article II and Article VIII.

                    (b) Notwithstanding  subparagraph (A) above, the Partnership
Term shall automatically terminate, unless the Partner not subject to the events
described in clauses (i)-(vii) below by written notice to the Partner subject to
such events within 30 days of the happening of any such event elects to continue
the Partnership, if either Partner shall (i) voluntarily commence any proceeding
or file any petition  seeking  relief  under Title 11 of the United  States Code
(other  than  Chapter  11  thereof)  or any  other  Federal,  state  bankruptcy,
insolvency, liquidation,  receivership or similar law (a "Bankruptcy Law"), (ii)
consent to the institution of, or fail to contravene in a timely and appropriate
manner, any such proceeding or the filing of any such petition,  (iii) apply for
or consent to the appointment of a receiver, trustee, custodian, sequestrator or
similar  official  for such party or for a  substantial  part of its property or
assets,  (iv) file an answer  admitting the material  allegations  of a petition
filed against it in any such proceeding,  (v) make a general  assignment for the
benefit of creditors,  (vi) take  corporate  action for the purpose of affecting
any of the foregoing or (vii) be subject to the  commencement of any involuntary
proceeding  or the filing of any  involuntary  petition in a court of  competent
jurisdiction  seeking  (A) relief in  respect of such party or of a  substantial
part  of any of its  property  or  assets  under  any  Bankruptcy  Law,  (B) the
appointment of a receiver, trustee, custodian,  sequestrator or similar official
for such party or for a  substantial  part of its  property or assets or (C) the
winding-up or  liquidation  of such party;  and in the case of this clause (vii)
such proceeding or petition shall continue  undismissed for 120 days or an order
or decree approving or ordering any of the foregoing shall continue unstayed and
in effect for 60 days.

               2.2  Buy/Sell Rights.

                    (a) Options to Sell or Purchase  Partnership  Interests.  If
(x) the Term of the Sales  Agency  Agreement  terminates  pursuant  to  Sections
8(b)(1) or 8(b)(2) thereof,  other than a termination that results from an event
described in such Section  8(b)(2) with respect to OTNC (as defined in the Sales
Agency Agreement), then the Partner affiliated with the party (for this purpose,
only the General Partner will be deemed  affiliated with the  Partnership)  that



                                       2







terminates the Sales Agency  Agreement shall elect or (y) the  Partnership  Term
terminates pursuant to Paragraph 2.1(b), then the Partner that is not subject to
the events  described in clauses (i) - (vii) of Paragraph  2.1(B) may elect,  in
each case  either (i) to  purchase  the  Partnership  Interest  (as such term is
defined  in  Paragraph  11.4) of the  other  Partner  or (ii) to cause the other
Partner to purchase such Partner's  Partnership Interest. A Partner may exercise
an option  described above only by giving written notice of such exercise to the
other Partner within 30 days following the  termination of the Term of the Sales
Agency  Agreement  or,  if such  option  is based  on  termination  pursuant  to
Paragraph  2.1(b),  within 30 days following the  termination of the Partnership
Term  pursuant  to such  paragraph.  If the Term of the Sales  Agency  Agreement
terminates  pursuant  to Section  8(b)(3) or 8(b)(4)  thereof,  then the General
Partner  shall  purchase,  and the  Limited  Partner  shall  sell,  the  Limited
Partner's  Partnership  Interest.  A Partner  having a purchase right under this
paragraph  may assign such right in whole or in part,  including  payment  terms
provided below, notwithstanding any other provision of this Agreement,  provided
that such  assignment will not relieve the assigning party or any guarantor from
any obligation.

                    (b) Closing.  Upon  exercise by a Partner of an option under
Paragraph  2.2(a),  or  upon a  termination  of the  Term  of the  Sales  Agency
Agreement  described  in the third  sentence of Paragraph  2.2(a),  the Partners
shall  be  legally  obligated  to  consummate  the  sale  and  purchase  of  the
Partnership  Interest  contemplated  thereby and shall use their respective best
efforts to secure any approvals required, and to comply with all applicable laws
and governmental  regulations,  in connection  therewith as soon as practicable.
The closing of the sale of the  relevant  Partner's  Partnership  Interest  (the
"Closing")  shall occur on the tenth business day following the later of (A) the
Determination  of the Appraised Value of such Partnership  Interest  pursuant to
Paragraph  2.2(D) and (B) the expiration of any required  governmental  or other
regulatory  waiting  periods and the obtaining of any required  governmental  or
other regulatory consents or approvals.

                    (c)  Purchase  Price;  Payment.  In the event of a sale of a
Partnership  Interest pursuant to this Paragraph 2.2, the purchase price of such
Partnership  Interest  shall be an amount equal to the  Appraised  Value of such
Partnership  Interest  determined  in accordance  with  Paragraph  2.2(d).  Such
purchase price shall be payable at the Closing in cash or, except in the case of
a termination of the Sales Agency Agreement pursuant to Section 8(b)(2) thereof,
or of the Partnership  Term pursuant to Paragraph  2.1(b),  at the option of the
purchasing Partner, by delivery to the selling Partner of a promissory note in a
form  reasonably  satisfactory  to the selling  Partner with a principal  amount
equal to the purchase price and containing the following  terms and  conditions:
(i) the note  shall be an  unsecured  obligation  of the  relevant  Partner  not
subordinated  to other  obligations of such Partner (but having no prior call as
to secured assets of such Partner) and shall be unconditionally guaranteed as to
payment of  principal  and  interest  by BMS or its  successor,  if the  Limited
Partner is the obligor, or by Axion or its successor,  if the General Partner is
the obligor;  (ii) one third of the original  aggregate  principal amount of the
note shall be payable on each of the first,  second and third  anniversaries  of
the Closing; (iii) the note will bear interest, payable quarterly in arrears, at
a  floating  rate of  interest  equal to the prime rate as set forth in the Wall
Street Journal;  (iv) the note will be mandatorily  prepayable in whole upon the
sale by the obligor or any affiliate thereof,  directly or indirectly, of all or
substantially all of


                                       3






the Partnership or its assets or business or a controlling  interest therein or,
if the obligor on the note is the General Partner, upon any Change in Control of
the General  Partner or Axion (other than the Change of Control that resulted in
the sale of the Partnership Interest pursuant to this Paragraph 2.2); and (v) if
the note was issued in  connection  with the purchase by the General  Partner of
the Limited Partner's Partnership Interest because of a termination of the Sales
Agency Agreement pursuant to Section 8(b)(1) thereof, then any principal payment
on the note may be paid by  delivering  to the Limited  Partner  shares of fully
paid and  nonassessable  common  stock of Axion or its  successor  that  have an
aggregate  Appraised  Value  equal  to the  amount  of such  principal  payment,
provided  that at the time of such  principal  payment  there  exists no default
under the note or event which,  after the passage of time or giving of a notice,
would constitute a default under the note. If the General Partner  purchases the
Partnership  Interest of the Limited  Partner  because of a  termination  of the
Sales Agency  Agreement  pursuant to Section 8(b)(1)  thereof,  then the General
Partner may elect to (i) assign the right to purchase the  Partnership  Interest
to Axion and/or (ii) pay or cause Axion to pay the purchase  price by delivering
to the Limited  Partner shares of fully paid and  nonassessable  common stock of
Axion or its  successor  that have an  aggregate  Appraised  Value  equal to the
purchase  price.  If shares of common stock are delivered to the Limited Partner
as described above, then  concurrently  therewith BMS and Axion or its successor
shall enter into a registration rights agreement containing terms and conditions
reasonably   satisfactory  to  BMS  and  Axion   (including  both  "demand"  and
"piggyback" registration rights); and provided further,  however, that the terms
and conditions of such registration  rights agreement shall be no less favorable
to BMS then the terms and conditions of any other registration  rights agreement
then in effect between Axion or its successor and any other party.

                    (d) Determination of Appraised Value. The Appraised Value of
a Partnership Interest to be sold pursuant to this Paragraph 2.2 shall equal the
fair market value of the  Partnership  Interest.  Such fair market value will be
determined  by first  determining  the  aggregate  fair market  value of all the
Partnership  Interests as a whole and as a going concern taking into account the
Extended Term of the Sales Agency  Agreement  (and the  nonexclusivity  thereof)
that will  remain  in  effect  following  the sale of the  relevant  Partnership
Interest,  and the  remaining  commitment  of the  General  Partner  to  provide
services   pursuant  to  Paragraph  7.8  following  the  sale  of  the  relevant
Partnership  Interest.  100% of such  determined  value  will then be  allocated
between the Partnership  Interests based on their relative economic rights under
this Agreement assuming continuation of the Partnership, provided, however, that
(i) the fair market value of the General  Partner's  Partnership  Interest shall
not reflect any  premium,  and the fair  market  value of the Limited  Partner's
Partnership  Interest shall not reflect any discount,  because of the respective
management  rights and  obligations of the Partners  pursuant to this Agreement;
and (ii) the fair market  value of the General  Partner's  Partnership  Interest
shall  not  reflect  any  discount,  and the fair  market  value of the  Limited
Partner's  Partnership  Interest  shall  not  reflect  any  premium,  due to the
relative  liabilities and potential  liabilities of the Partners.  The Appraised
Value of the relevant  Partnership Interest shall be agreed upon by the Partners
or, failing such  agreement,  shall be  conclusively  determined by a nationally
recognized  investment  banking firm  jointly  selected by the Partners for such
purpose. The Partners shall use their best efforts to cause any determination of
the Appraised Value of a Partnership Interest (and common stock as


                                       4






mentioned  below) to be made  within  30 days  after the  parties  first  become
obligated  to sell and  purchase a  Partnership  Interest  pursuant to Paragraph
2.2(a).  The  Appraised  Value of any  shares  of  common  stock of Axion or its
successor  shall be  determined  as of the  relevant  payment date on which such
stock is required to be  delivered  and shall be agreed upon by the Partners or,
failing  such  agreement,  shall  be  conclusively  determined  by a  nationally
recognized  investment  banking firm  jointly  selected by the Partners for such
purpose. The fees and expenses of any firm making a valuation as described above
shall be shared  equally by the  Partners.  Notwithstanding  the  foregoing,  if
shares  of  common  stock of Axion or its  successor  are  traded on one or more
securities  exchanges  or traded  on the  NASDAQ  National  Market  System,  the
Appraisal  Value of such common stock shall be deemed to be the average  closing
price of such common stock as reported in the Wall Street Journal for the thirty
(30) days preceding the relevant payment date on which such stock is required to
be delivered.


                                   ARTICLE III

                              CAPITAL CONTRIBUTIONS

               3.1  Initial Capital Contributions of the Partners.

                    (a) Contributions of Each Partner. Within five business days
after the date of this Agreement (the "Initial Contribution Date"), each Partner
shall contribute  capital,  in cash, to the Partnership payable by wire transfer
or check in an amount equal to $500,000.  On August 23, 1993, each Partner shall
contribute  capital,  in cash,  to the  Partnership  payable by wire transfer or
check in an amount equal to an additional  $500,000  (together,  such  Partners'
"Initial Contribution").

                    (b) General Partner's  Contribution.  Effective as of August
23, 1993,  the General  Partner  shall  contribute  all of its right,  Title and
interest in the ongoing Oncology  Therapeutics  Network business as of such date
of the General Partner as of such date (except those excluded from the following
representation  and  warranty);  provided  that from the date of this  Agreement
through the date of such  contribution,  the General  Partner shall conduct such
business in the ordinary  course;  provided,  however,  that the General Partner
shall not transfer,  and the  Partnership  shall not assume,  any  obligation or
liability  of any kind or nature,  primary  or  secondary,  direct or  indirect,
absolute or contingent, known or unknown, whether or not accrued, arising before
such contribution,  of the General Partner,  Axion or any affiliate thereof. The
General Partner  represents,  warrants and covenants to the Partnership that the
business to be contributed  will constitute the entire ongoing  business (except
as  otherwise  contemplated  herein)  of the  General  Partner,  Axion and their
respective  Controlled  Affiliates  (as defined in the Sales  Agency  Agreement)
relating to the  distribution  of oncology  drugs and  biologics  (other than in
connection  with clinical  trials or research) to the Customer Group (as defined
in the  Sales  Agency  Agreement)  on  behalf of third  parties  (the  "Oncology
Distribution   Business"),   including,   without   limitation,   all   Oncology
Therapeutics  Network  membership  data  and  sales  and  distribution  know-how
relating to the Oncology Distribution  Business,  but excluding tangible assets,
people,  operational  or  administrative  functions  or the like,  and  accounts
receivable.


                                       5






                    (c) Limited  Partner's  Contribution.  The  Limited  Partner
shall  contribute to the Partnership  certain  Bristol-Myers  Oncology  Division
customer lists.

               3.2  Additional  Capital  Contributions  of Partners.  Except  as
required in subparagraphs  3.1(b) and 3.1(c) and Paragraph 3.3, no Partner shall
be required to contribute  additional  capital to the  Partnership  in excess of
such  Partner's  Initial  Contribution  except with the Special  Approval of the
Management Committee.

               3.3 Future Capital Needs. The Partners  shall use their  combined
best  efforts  to enable  the  Partnership  to  establish  and  maintain  credit
facilities  adequate to fund the  Partnership's  working capital and fixed asset
needs;  provided,  however,  that no  Partner  will be  obligated  to  provide a
guarantee  or  other  credit  support  for  any  Partnership  obligation  or any
financing  unless such Partner consents  thereto.  Any additional debt or equity
financing required by the Partnership shall be provided by borrowings from third
parties or from the Partners or by cash capital  contributions from the Partners
provided  that  any  such   borrowings,   other  than  trade  debt,  or  capital
contributions  will require the Special  Approval of the  Management  Committee:
provided,  however,  Partnership  borrowings  from parties other than  Partners,
other than trade debt, in an aggregate amount  outstanding at any one time of up
to  $1,000,000  shall  not  require  the  Special  Approval  of  the  Management
Committee.

               3.4  Liability  of  Limited Partner.  Subject  to  any  guarantee
pursuant to Paragraph  3.3, the Limited  Partner  shall not be liable for any of
the debts, liabilities or obligations of the Partnership or any of the losses of
the  Partnership  beyond the amount of the  Limited  Partner's  Initial  Capital
Contribution  and any  additional  capital  contributions,  except to the extent
otherwise  required by law. The Limited Partner shall not be responsible for any
debts or losses of the General  Partner  (other than as reflected in the Limited

                              SALES AGENCY AGREEMENT

                         CAPITAL ACCOUNTS AND ALLOCATIONS

               5.1 Capital Accounts.  A Capital  Account shall  be maintained on
the Partnership's  books for each  Partner in accordance with generally accepted
accounting  principles except as otherwise  specifically required herein. Solely
for purposes of maintaining  Capital


                                       6







Accounts the parties hereto agree that the in-kind  contributions of the General
Partner  and the  Limited  Partner  set forth in  subparagraphs  3.1(b) and (c),
respectively,  shall be  deemed  to be  valued  at zero  (0).  In the  event any
interest in the  Partnership is transferred in accordance with the terms of this
Agreement, the transferee shall succeed to the Capital Account of the transferor
to the extent it relates to the transferred interest.

               5.2  Definitions.  Unless the  context  requires  otherwise,  the
following terms have the meanings specified in this Paragraph:

                    (a) Fiscal Year: The  Partnership's  first Fiscal Year shall
begin  on the  date  hereof  and  end on  December  31,  1993.  Thereafter,  the
Partnership's  Fiscal  Year shall  commence on January 1 of each year and end on
December 31 of such year or, if  earlier,  the date the  Partnership  terminated
during such year pursuant to Paragraph 2.1 or otherwise.  The Fiscal Year of the
Partnership shall end on the date the Partnership  terminates in accordance with
the terms of Article II.

                    (b) General Partner Annual  Preference  Amount:  The General
Partner Annual Preference Amount for each Fiscal Year shall be as follows:

                        Fiscal Year                 Amount
                        -----------                 ------
                            1993                $     900,000
                            1994                    4,900,000
                            1995                   10,200,000
                            1996                   18,750,000
                    1997 and Thereafter                     0


However,  to the  extent  that the  Capital  Account of the  General  Partner is
allocated any Net Liquidating Income pursuant to subparagraph  5.3(b)(iii),  the
General Partner Annual  Preference Amount will be reduced (but in no event below
zero) on a  dollar-for-dollar  basis in chronological order, commencing with the
General  Partner  Annual  Preference  Amount  for the  Fiscal  Year  immediately
following  the Fiscal Year with  respect to which the  subparagraph  8.3(b)(iii)
allocation occurs.  For example,  if Ten Million Four Hundred and Fifty Thousand
Dollars ($10,450,000) of 1994 Net Liquidating Income is allocated to the Capital
Account of the General Partner pursuant to subparagraph 5.3(b)(iii), the General
Partner  Annual  Preference  Amount for Fiscal Year 1995 will be reduced to zero
(0) and the General Partner Annual  Preference  Amount for Fiscal Year 1996 will
be reduced to Eighteen Million Five Hundred Thousand Dollars  ($18,500,000).  If
Three  Hundred  Thousand  Dollars of 1995 Net  Liquidating  Income is thereafter
allocated to the Capital Account of the General Partner pursuant to subparagraph
5.3(b)(iii),  the General Partner Annual  Preference Amount for Fiscal Year 1996
will be reduced to Eighteen Million Two Hundred Thousand Dollars ($18,200,000).

                    (c)  General  Partner  Cumulative   Preference  Amount.  The
General  Partner  Cumulative Preference Amount shall initially  equal  zero  and
shall equal zero


                                       7






immediately  prior to the close of the 1993 Fiscal Year.  Immediately  following
the close of a Fiscal  Year the General  Partner  Cumulative  Preference  Amount
shall be equal to (i) the sum of (A) the General Partner  Cumulative  Preference
Amount that existed immediately prior to the close of such Fiscal Year, plus (B)
the General Partner Annual Preference for such Fiscal Year, less (ii) the sum of
the amounts of Net Operating Income and Net Liquidating  Income allocated to the
Capital  Account of the  General  Partner  pursuant  to clauses  (i) and (ii) of
Paragraphs  5.3(a) and 5.3(b),  respectively,  with respect to such Fiscal Year.
The General Partner  Cumulative  Preference Amount that exists immediately prior
to the close of any Fiscal Year shall be equal to the product of (A) the General
Partner  Cumulative  Preference  Amount that existed  immediately  following the
close of the preceding Fiscal Year multiplied by (B) the sum of one (1) plus the
average of the prime  rates of  interest  (expressed  as a decimal  and based on
annual  compounding) on each Friday within the last month of such Fiscal Year as
set forth in the Wall Street Journal.

                    (d) Income Sharing Percentages. For Fiscal Years 1993, 1994,
1995,  and 1996 the Income Sharing  Percentages  of the General  Partner and the
Limited  Partner  shall be  eighty  percent  (80%)  and  twenty  percent  (20%),
respectively. For Fiscal Year 1997 the Income Sharing Percentages of the General
Partner  and the  Limited  Partner  shall be  seventy  percent  (70%) and thirty
percent (30%), respectively. For Fiscal Year 1998 the Income Sharing Percentages
of the General  Partner and the Limited Partner shall be sixty percent (60%) and
forty percent  (40%),  respectively.  For all periods after Fiscal Year 1998 the
Income Sharing  Percentages of the General Partner and the Limited Partner shall
be fifty percent (50%) and fifty percent (50%), respectively.

                    (e) Net Liquidating Income and Net Liquidating Loss: The net
income  and net  losses,  respectively,  of the  Partnership  as  determined  in
accordance with generally  accepted  accounting  principles (except as otherwise
expressly set forth in this Agreement),  taking into account only those items of
income,  gain, loss and expense  attributable to sales or other  dispositions of
all or any significant  portion of the business of the  Partnership  (other than
sales of inventory in the ordinary course of the  Partnership  business) and all
other items of income,  gain,  loss and expense  attributable  to other than the
ordinary operation of the Partnership business.  For purposes of determining Net
Liquidating  Income and Net Liquidating Loss, any payment (or deemed payment) to
the Partners pursuant to subparagraph  8.1(b)(iii)  (relating to Capital Account
Prime Rate  Amounts)  shall be accounted for as an item of  Partnership  expense
taken into account in determining  Net  Liquidating  Income and Net  Liquidating
Loss.

                    (f) Net  Operating  Income and Net Operating  Loss:  The net
income  and net  losses,  respectively,  of the  Partnership  as  determined  in
accordance with generally  accepted  accounting  principles (except as otherwise
expressly  set forth  herein),  taking into  account only those items of income,
gain, loss and expense attributable to the ordinary operation of the Partnership
business.  For purposes of  determining  Net Operating  Income and Net Operating
Loss, any payment (or deemed payment) to the Partners  pursuant to Paragraph 6.2
(relating to Capital  Account Prime Rate  Amounts)  shall be accounted for as an
item of Partnership  expense taken in determining  Net Operating  Income and Net
Operating Loss.

               5.3 Allocation of Net Income and Net Loss.

                    (a) Net Operating Income for each Fiscal Year, if any, shall
be allocated as follows:

                         (i) First,  one hundred  percent  (100%) to the Capital
Account  of the  General  Partner  until the  General  Partner  shall  have been
allocated an amount of Net Operating Income pursuant to this clause (i) for such
Fiscal Year equal to the General Partner  Cumulative  Preference Amount, if any,
existing immediately prior to the close of such Fiscal Year;

                         (ii) Next,  one hundred  percent  (100%) to the Capital
Account  of the  General  Partner  until the  General  Partner  shall  have been
allocated  an amount of Net  Operating  Income  pursuant to this clause (ii) for
such Fiscal Year equal to the General Partner Annual Preference  Amount, if any,
for such Fiscal Year; and

                         (iii) Finally, any Net Operating Income remaining after
effecting the  allocations set forth in  subparagraphs  5.3(a)(i) and 5.3(a)(ii)
above shall be allocated to the Capital  Accounts of the General Partner and the
Limited Partner in proportion to their respective Income Sharing Percentages for
such Fiscal Year.

                    (b)  After  effecting  the   allocations   provided  for  in
subparagraph  (a) above,  Net Liquidating  Income,  if any, for each Fiscal Year
shall be allocated as follows:

                         (i) First,  one hundred  percent  (100%) to the Capital
Account  of the  General  Partner  until the  General  Partner  shall  have been
allocated an amount of Net  Liquidating  Income  pursuant to this clause (i) for
such Fiscal Year equal to the excess, if any, of the General Partner  Cumulative
Preference  Amount,  if any,  existing  immediately  prior to the  close of such
Fiscal Year over the amount of Net  Operating  Income  allocated  to the General
Partner  with  respect to such Fiscal Year  pursuant to  subparagraph  5.3(a)(i)
above;

                         (ii) Next,  one hundred  percent  (100%) to the Capital
Account  of the  General  Partner  until the  General  Partner  shall  have been
allocated an amount of Net  Liquidating  Income pursuant to this clause (ii) for
such  Fiscal Year equal to the excess,  if any,  of the General  Partner  Annual
Preference Amount, if any, for such Fiscal Year over the amount of Net Operating
Income  allocated  to the  General  Partner  with  respect to such  Fiscal  Year
pursuant to subparagraph 5.3(a)(ii) above;

                         (iii) Next,  one hundred  percent (100%) to the Capital
Account  of the  General  Partner  until the  General  Partner  shall  have been
allocated an amount of Net Liquidating  Income pursuant to this clause (iii) for
such  Fiscal  Year equal to the sum of the  General  Partner  Annual  Preference
Amounts, if any, for all Fiscal Years following such Fiscal Year; and


                                       9







                         (iv)  Finally,  any Net  Liquidating  Income  remaining
after effecting the allocations set forth in subparagraphs 5.3(b)(i), 5.3(b)(ii)
and 5.2(b)(iii)  above shall be allocated to the Capital Accounts of the General
Partner and the Limited Partner in proportion to their respective Income Sharing
Percentages for such Fiscal Year.

                    (c) Net Operating Loss and Net Liquidating Loss, if any, for
each Fiscal Year (from whatever  source  derived) shall be allocated  equally to
the  Capital  Account of the  General  Partner  and the  Capital  Account of the
Limited Partner.

                    (d)  Notwithstanding   the  foregoing   provisions  of  this
Paragraph  5.3, any item of  Partnership  expense  related to the payment of any
amounts  pursuant to  Paragraphs  6.2 or  8.1(b)(iii)  hereof shall be specially
allocated to the Capital  Accounts of the General Partner and Limited Partner in
equal amounts.

                    (e)  Notwithstanding   the  foregoing   provisions  of  this
Paragraph 5.3, to the extent the  Partnership is liable to BMS for breach of the
Trademark  License  Agreement,  all  Partnership  losses and expenses  resulting
directly  therefrom  shall be  allocated  to the Capital  Account of the General
Partner.

                    (f)  Notwithstanding   the  foregoing   provisions  of  this
Paragraph  5.3, all  Partnership  losses and expenses  relating  directly to the
indemnification of any Partner pursuant to any provision of this Agreement shall
be  allocated  to the Capital  Accounts  of the Limited  Partner and the General
Partner in equal amounts.

               5.4  Reallocation  of  Negative  Balance.   Notwithstanding   the
foregoing provisions of this Article V:

                         (i) In no  event  will  an  allocation  be  made to the
Limited Partner if such  allocation  would cause the Limited  Partner's  Capital
Account balance to be negative (or increase the amount by which it is negative);

                         (ii) In the event  that the  provisions  of clause  the
allocations  that are  otherwise  required by this Article V, then to the extent
possible without contravening such clause (i) provisions, subsequent allocations
shall be effected so as to cause the Capital Account balances of each Partner to
be equal to the  balances  that would have  existed  had no such  alteration  of
allocations occurred pursuant to clause (i) hereof; and

                         (iii) To the extent possible  without  contravening the
provisions  of clauses (i) or (ii) above,  in the event that the  provisions  of
clause (i) above apply to alter the allocations  that are otherwise  required by
this Article V, subsequent allocations shall be effected in a manner that causes
each Partner to have received over the life of the  Partnership  the same amount
of Net Operating  Income,  Net Operating  Loss, Net  Liquidating  Income and Net
Liquidating  Loss as such Partner would have received had no such  alteration of
allocations occurred pursuant to clause (i) hereof.

                                   ARTICLE VI

          WITHDRAWALS BY AND DISTRIBUTIONS AND PAYMENTS TO THE PARTNERS

               6.1  Interest and Withdrawals.

                         (a) Without  restricting  or limiting  Paragraphs  6.2,
8.1(b)(iii)  or 5.2(c),  no interest  shall be paid to any Partner on account of
its  interest  in the  capital  of, or on  account  of its  investment  in,  the
Partnership.

                         (b) No Partner may withdraw any amount from its Capital
Account  unless  such  withdrawal  is made  pursuant  to this  Article  VI or is
otherwise expressly permitted by this Agreement.

               6.2  Mandatory Payment. Each Partner  shall  promptly  (and in no
event  later than  ninety  (90) days after the end of each of the  Partnership's
Fiscal Years) be paid out of any available cash (prior to distributing  any such
cash pursuant to the remaining provisions of this Article VI) an amount equal to
the Capital Account Prime Rate Amount for such Partner  existing as of the close
of such Fiscal Year. The "Capital Account Prime Rate Amount" for a Partner shall
initially equal zero and shall as of the close of the 1993 Fiscal Year equal the
product  of (i) the  average  positive  balance in the  Capital  Account of such
Partner during such Fiscal Year, multiplied by (ii) a fraction, the numerator of
which is the number of calendar  months  between the date of this  Agreement and
the end of the 1993 Fiscal  Year and the  denominator  of which is twelve  (12),
multiplied  by (iii) the average of the prime rates of interest  (expressed as a
decimal  and based on annual  compounding)  on each  Friday  within the month of
December  of such  Fiscal  Year as set  forth in the Wall  Street  Journal.  The
"Capital  Account  Prime  Rate  Amount"  for a  Partner  as of the close of each
succeeding Fiscal Year shall equal the product of (i) the sum of (A) the average
positive  balance in the Capital Account of such Partner during such Fiscal Year
plus (B) the excess of the sum of the  Capital  Account  Prime Rate  Amounts for
such Partner for each of the preceding  Fiscal Years of the Partnership over the
aggregate amounts paid to such Partner with respect to all such preceding Fiscal
Years  pursuant to this  Paragraph  6.2,  multiplied  by (ii) the average of the
prime rates of interest (expressed as a decimal and based on annual compounding)
on each Friday within the last  calendar  month of such Fiscal Year as set forth
in the Wall Street  Journal,  multiplied  by (iii) a fraction,  the numerator of
which is the number of calendar  months in such Fiscal Year and the  denominator
of which is twelve (12).  Payments made to a Partner  pursuant to this Paragraph
6.2 shall not reduce the Capital Account balance of such Partner.

               6.3 Mandatory Cash  Distributions  of General Partner  Preference
Amount. Promptly after the end of each of the Partnership's Fiscal Years (but in
no event later than ninety (90) days after the end of each such Fiscal Year) the
General Partner shall receive a cash  distribution from the Partnership equal to
the excess of (i) the aggregate  amount of Net Operating Income allocated to the
General  Partner  for such Fiscal Year and all prior  Fiscal  Years  pursuant to
clauses (i) and (ii) of Paragraph 5.3(a) (relating to the General Partner Annual
Preference


                                       11






Amount and General Partner Cumulative Preference Amount) over (ii) the aggregate
cash distributions  previously  received by the General Partner pursuant to this
Paragraph 6.3.

               6.4 Tax Distributions. The General Partner may in its discretion,
or upon the request of the Limited  Partner  shall,  distribute  to the Partners
within  ninety (90) days of the end of each Fiscal Year up to an amount equal to
forty  percent  (40%) of the Net  Operating  Income  allocated to the  Partners'
Capital  Accounts  pursuant to clause (iii) of Paragraph  5.3(a) with respect to
such Fiscal Year; provided, however, that (a) no such distribution shall be made
with  respect to any  Fiscal  Year in which the  Partnership  has a net loss for
federal income tax purposes and (b) such distribution  shall be made only to the
extent such  distribution  is made from cash not  reasonably  necessary  for the
Partnership's operations. In the event that the maximum marginal rate of federal
income tax  applicable to  corporations  is increased or decreased from the rate
applicable  as of the date first set forth  above,  the  General  Partner  shall
adjust such forty  percent  (40%) figure to take into  account such  increase or
decrease  for the  Fiscal  Years to which such  increase  or  decrease  applies,
provided that the percent  figure as adjusted  shall not exceed six (6%) percent
plus the maximum  marginal  federal  rate.  All  distributions  to the  Partners
pursuant to this  Paragraph 6.4 with respect to any Fiscal Year shall be made in
proportion  to the  amount  of Net  Operating  Income  allocated  to  each  such
Partner's  Capital  Account  pursuant to clause (iii) of  Paragraph  5.3(a) with
respect to such Fiscal Year.

               6.5 Discretionary Distributions of Net Operating Income. Prior to
the  Date  of  Termination,  the  General  Partner  may in its  discretion  make
distributions  of cash during any Fiscal  Year in  addition  to those  otherwise
required or allowable  under this Article VI provided  that, at the time of such
distribution,  the  Partnership  has no material  indebtedness  other than trade
debt. If at any time the Partnership has material  indebtedness other than trade
debt or following any cash  distribution the Partnership would be expected to be
required to incur material indebtedness other than trade debt on account of such
cash distribution, no such distribution shall be made pursuant to this Paragraph
6.5 without the Special Approval of the Management  Committee. All distributions
pursuant to this  Paragraph 6.5 shall be made in amounts up to and in proportion
to (i) in the case of the Limited  Partner,  the excess,  if any, of the Capital
Account  balance of the Limited  Partner as of the  commencement  of such Fiscal
Year over the Limited  Partner's  Retained  Net  Liquidating  Income  Amount (as
defined in Paragraph 6.6) as of the commencement of such Fiscal Year and (ii) in
the case of the  General  Partner,  the excess,  if any, of the Capital  Account
Balance of the General  Partner as of the  commencement of such Fiscal Year over
the sum of the General  Partner's  Retained Net  Liquidating  Income  Amount (as
defined in Paragraph 6.6) as of the date of the commencement of such Fiscal Year
plus the  maximum  amount  the  General  Partner  would be  entitled  to receive
pursuant  to  Paragraph  6.3  as  of  the  commencement  of  such  Fiscal  Year.
Notwithstanding  the foregoing,  in the event that the Limited  Partner has been
distributed an amount pursuant to Paragraph 6.9, no  distribution  shall be made
to the Limited Partner  pursuant to this Paragraph 6.5 until the General Partner
has been  distributed an amount equal to that distributed to the Limited Partner
pursuant to Paragraph 6.9.

               6.6  Distributions of Net Liquidating Income. The General Partner
may, from time to time, in its sole  discretion  distribute  cash to each of the
Partners in amounts up to and in


                                       12






proportion to their  respective  Retained Net Liquidating  Income  Amounts.  The
"Retained  Net  Liquidating  Income  Amount" for each  Partner at any time shall
equal  the  excess,  if  any,  of (i)  the  aggregate  amount,  if  any,  of Net
Liquidating  Income  allocated  to the Capital  Account of such  Partner for all
periods (net of any Net  Liquidating  Loss so allocated) over (ii) the aggregate
amount of distributions  received by such Partner pursuant to this Paragraph 6.6
for all such periods.

               6.7  Equivalency  Distribution.  Commencing  on  January 1, 1999,
within ninety (90) days of the commencement of each Fiscal Year a Partner with a
Capital  Account  balance that exceeds the Capital  Account balance of the other
Partner  (determined as of the close of the immediately  preceding  Fiscal Year)
shall be distributed the amount of such excess.

               6.8  Limitation on Distributions.  Notwithstanding  the foregoing
provisions of this Article VI, in no event will a Partner receive a distribution
to the extent  that such  distribution  causes  such  Partner to have a negative
balance in its Capital Account (or increases the amount by which such balance is
negative).

               6.9  Limited  Partner  Return  of  Capital  Distribution.  As  of
December 15, 1993  (but  not after  such  date),  the Limited Partner may at its
option  elect to receive a  distribution  up to an amount equal to the excess of
the  amount  of  the  Limited   Partner's  Initial  Contribution  over  $300,000
(regardless of whether such  distribution  causes  the Limited Partner to have a
negative balance in its  Capital Account  or  increases the amount by which such
balance is negative).

               6.10 Tax  Distribution Treatment. For purposes of Paragraphs 6.5,
6.7 and 6.8, the  Partners'  Capital  Account  balances  shall be  determined by
treating  distributions  made or expected to be made  pursuant to Paragraph  6.4
within 90 days of the end of a Fiscal  Year as if they had been made on the last
day of such Fiscal Year.


                                   ARTICLE VII

                    MANAGEMENT, DUTIES, AND RESTRICTIONS

               7.1 Management. Except as expressly provided herein,  the General

with such information with respect to the business and affairs of Partnership as

action requiring such approval.

                    (b) Access to Information and Personnel. The Limited Partner
and any member of the Management Committee and their representatives, employees,
counsel and accountants,  shall upon reasonable notice to the General Partner or
the  Partnership  be  furnished  with,  or given  access  to,  such  information
(including  all  books and  records)  as  reasonably  requested  by such  person
relating to the business of the Partnership. Furthermore, any person making such
request shall have the right to review and audit such information (including all
books and records) to its  satisfaction.  The Limited  Partner and any member of

Partner  Designees"),  two of which shall be designated  by the Limited  Partner
("Limited  Partner  Designees"),  and two of which shall be designated by mutual
agreement  of the  General  Partner and the Limited  Partner  (the  "Independent
Members").  Each Management  Committee  member will serve at the pleasure of the
Partner or Partners designating such member and may be replaced, with or without
cause,  at any time by such Partner or Partners.  An  Independent  Member of the
Management  Committee may be removed or replaced only by mutual agreement of the
General  Partner and the Limited  Partner.  Written  notice of  replacement of a
designee  of one  Partner  shall be given to the other  Partner and shall not be
effective until received.

                    (d)  Quorum;   Voting   Requirements.   A  majority  of  the
authorized  number of members of the  Management  Committee  shall  constitute a
quorum at any regular or special meeting.  No action may be taken at any regular
or special meeting unless a quorum is present at such meeting. The approval of a
majority  of the  members of the  Management  Committee  present at a meeting at
which the foregoing  quorum  requirement is satisfied  shall be required to take
any action by the  Management  Committee;  provided,  however,  that the matters
referred to in Paragraph  7.2(j) shall in all events  require the approval of at
least one Limited Partner  Designee and one General Partner  Designee  ("Special
Approval").

                    (e) Regular  Meetings.  The Management  Committee shall meet
regularly at the times and places  which it may  determine,  provided  that such
meetings  shall  be  held  at  least  semi-annually.  Regular  meetings  of  the
Management  Committee may be held without notice at such times and places as the
Management  Committee may from time to time determine,  provided that reasonable
notice of the first regular meeting  following any such  determination  shall be
given to members absent from the meeting at which such determination was made.

                    (f) Special  Meetings.  A special  meeting of the Management
Committee  may be  called  by the  Management  Committee,  the  Chairman  of the
Management  Committee  (as  defined  in  Paragraph  7.3  below) or by a Partner.
Special meetings may be held on any date and at any place and time designated in
the call of the meeting,  reasonable  notice  thereof  having been given to each
member of the Management Committee.

                    (g)   Meeting   by    Conference    Telephone   or   Similar
Communications  Equipment.  Meetings of the Management  Committee may be held by
means of conference  telephone or similar  communications  equipment by means of
which all  persons  participating  in a meeting can hear and speak to each other
simultaneously.

                    (h) Actions by Writing.  Any action required or permitted to
be taken at any  meeting  of the  Management  Committee  may be taken  without a
meeting if the number of members of the Management Committee required to approve
such  action at a meeting  attended  by all  members  consent  to the  action in
writing and the written  consents  are filed with the records of the meetings of
the Management  Committee.  Such consents shall be treated for all purposes as a
vote at a meeting.

                    (i) Notice.  A member of the Management  Committee  shall be
deemed to have received  reasonable notice of a meeting if written notice of the
date,  time and place of the meeting is  delivered  to such member by mail or by
nationally  recognized  overnight  courier  at  least 3 days in  advance  of the
meeting.  In an  emergency,  notice  of a meeting  given  orally in person or by
telephone  call at  least  forty-eight  (48)  hours  before  the  meeting  shall
constitute  reasonable  notice.  Notice  of a  meeting  need not be given to any
member of the Management  Committee if a written  waiver of notice,  executed by
the member at any time,  is filed with the  records  of the  meeting,  or to any
member  who  attends  a  meeting  without  protesting  prior  thereto  or at its
commencement the lack of notice to the member.

                    (j) Partnership  Major  Decisions.  The  "Partnership  Major

               (4) any adoption or material  amendment of or,  unless out of the
Partnership's  reasonable control,  material deviation from the Annual Operating
and  Capital  Budget of the  Partnership,  provided,  however,  that if any such
amendment  or  deviation  is the  result of any event that  would  constitute  a
Partnership Major Decision (other than pursuant to this subparagraph  7.2(j)(4))
except that it is  specifically  excluded or does not meet the  relevant  dollar
threshold,  then such amendment or deviation  shall not constitute a Partnership

                                       16






               Notwithstanding  anything  else,  no  Special  Approval  shall be
required for any action required or permitted by Paragraph 2.2 of this Agreement
or Section 8 of the Agency Agreement.

               7.3  Chairman. The Chief Executive  Officer of Axion shall be the
Chairman of the Management Committee.

               7.4 No Control by the Limited  Partner. The Limited Partner shall
take no part in the control or management of the affairs of the  Partnership nor
shall the  Limited  Partner  have any  authority  to act for or on behalf of the
Partnership except as is specifically permitted by this Agreement.

               7.5  Admission of Additional Partners.

                    (a) No additional person may be admitted to the Partnership,
either as a limited or general  partner,  without the prior  written  consent of
both the General Partner and the Limited Partner.

               7.6  Transfer of Partnership Interests.

                    (a) Transfers.  Except for Permitted  Transfers as set forth
in paragraphs  (b) and (c) below,  no Partner may directly or  indirectly  sell,
assign or transfer,  including,  without  limitation,  by operation of law or in
connection with a merger, sale of stock, or sale of substantially all the assets
or similar  transaction by a Partner (any such transfer is hereinafter  called a
"Transfer"), any part or all of the Partnership Interest of such Partner without
the prior  written  consent of the other  Partner  which may be withheld in such
Partner's sole discretion.  Without limiting the generality of the foregoing,  a
Change in Control  (as  defined in the Sales  Agency  Agreement)  of the General
Partner  shall be deemed to constitute a Transfer that shall require the Limited
Partner's  consent  pursuant  to this  Paragraph  7.6(a),  however,  a Change in
Control of Axion  shall not be deemed to be a Change in  Control of the  General
Partner for purposes of this-Paragraph 7.6(a).

                    (b) Limited Partner Permitted Transfers. The Limited Partner
may at any time,  without the consent of the General Partner,  Transfer all (but
not less than all) of its  Partnership  Interest  to BMS,  or any entity  wholly
owned,  directly or indirectly,  by BMS; provided,  however, that the transferee
shall  possess  the legal  capacity to fulfill  the  obligations  of the Limited
Partner   hereunder   (such   transferee   being  a   "Permitted   Transferee").
Notwithstanding  the provisions of  subparagraphs  (a) and (b), the  Partnership
Interest  of the  Limited  Partner  shall at all times be held by a person  that
would be a Permitted Transferee of the Limited Partner's  Partnership  Interest.
The Limited  Partner  shall notify the General  Partner of any such  Transfer at
least ten days prior to the date of the  Transfer.  Upon  request by the General
Partner,  the Limited  Partner  promptly  shall  provide to the General  Partner
information  reasonably  adequate to permit the General  Partner to evaluate the
adequacy of the legal capacity of the Permitted Transferee.  A Change in Control
of the Limited Partner shall at all times




                                       17






constitute an  unpermitted  Transfer under this Paragraph 7.6(b) and require the
consent of the General Partner.

                    (c) General Partner Permitted Transfers. The General Partner
may at any time,  without the consent of the Limited Partner,  Transfer all (but
not less than all) of its  Partnership  interest  to Axion or any entity  wholly
owned, directly or indirectly, by Axion; provided,  however, that the transferee
shall  possess  the legal  capacity to fulfill  the  obligations  of the General
Partner   hereunder   (such   transferee   being  a   "Permitted   Transferee").
Notwithstanding  the  provisions  of  paragraphs  (a) and (c),  the  Partnership
Interest  of the  General  Partner  shall at all times be held by a person  that
would be a Permitted Transferee of the General Partner's  Partnership  Interest.
The  General  Partner  shall  notify the  Limited  Partner of any such  proposed
Transfer at least ten days prior to the date of the  Transfer.  Upon  request by
the Limited  Partner,  the General Partner promptly shall provide to the Limited
Partner  information  reasonably  adequate  to permit  the  Limited  Partner  to
evaluate  the  adequacy of the legal  capacity of the  Permitted  Transferee.  A
Change in  Control  of the  General  Partner  shall at all times  constitute  an
unpermitted  Transfer under this Paragraph 7.6(c) and require the consent of the
Limited Partner; provided,  however, that a Change in Control of Axion shall not
constitute a Change in Control of General  Partner for purpose of this Paragraph
7.6(c).

                    (d) No Transfer or other  disposition  of the  interest of a
Partner shall be permitted  until the Management  Committee shall have received,
or waived receipt of, an opinion of counsel  satisfactory  to it that the effect
of such transfer or disposition would not:

                              (i) result in a violation of the Securities Act;

                              (ii)  require  the  Partnership  to register as an
investment company under the Investment Company Act of 1940, as amended;

                              (iii)   require  the   Partnership,   the  General
Partner,  or any  partner of the General  Partner to  register as an  investment
adviser under the Investment Advisers Act of 1940, as amended;

                              (iv) result in a  termination  of the  Partnership
for tax purposes;

                              (v) result in a  violation  of any law,  rule,  or
regulation by the Limited Partner, the Partnership,  the General Partner, or any
partner of the General Partner; or

                              (vi) increase the number of Limited Partners.

                    (e) A Permitted Transferee shall upon satisfaction of all of
the  requirements  set forth above in this Paragraph  7.6,  become a substituted
Limited  Partner  (in  the  case  of a  transfer  by  the  Limited  Partner)  or
substituted  General Partner in the case of a transfer by the General Partner by
(i)  delivery  of written  notice of election  to become a  substituted  Limited
Partner  or General  Partner,  as the case may be, to the  Partnership  and (ii)
executing  and  acknowledging  such  other  instruments  as the  nontransferring
Partner may  reasonably  deem  necessary or advisable to effect the admission of
such Permitted Transferee as a substituted



                                       18






Partner including,  without  limitation,  the written acceptance and adoption by
such Permitted Transferee of the provisions of this Agreement. No Transfer shall
be effected  pursuant to  Paragraphs  7.6(b) or (c) above until such time as the
requirements  of clauses (i) and (ii) of the preceding  sentence shall have been
satisfied. No consent of the nontransferring Partner shall be required to effect
the substitution of a Partner as provided in this Paragraph 7.6(e).

               Such legal opinion shall be provided to the Management  Committee
by the transferring Partner or the proposed transferee, and all reasonable costs
associated with such opinions shall be borne by the transferring  Partner or the
proposed transferee.

               7.7  Deadlock;  Dispute.  If  there  is  a  deadlock  or  dispute
regarding the  Partnership  (whether  between  the Partners or at the Management
Committee  level or  otherwise),  the  Partners will  use their  good faith best
efforts and act reasonably to resolve the dispute or deadlock.  If these efforts
are unsuccessful,  either Partner may request non-binding mediation with respect
to any dispute or deadlock,  and the  non-requesting  Partner  shall be required
to submit  thereto and both Partners shall act reasonably and in good faith with
respect  thereto.  All costs of mediation  incurred by the Partners  pursuant to
this Paragraph 7.7 shall be paid by the Partnership.

               7.8  Services; Reimbursement.

                    (a)  Services.  The  General  Partner  shall  provide to the
Partnership  such  administrative  and  operational and other services as may be
needed by the  Partnership  to conduct  its  business  ("Services"),  including,
without limitation, the following:

                              (i) General administrative services, including the
overall  supervision and  administration  of the operation of the  Partnership's
business;

                              (ii)   Bookkeeping  and  accounting   services  to
support the operation of the Partnership's business;

                              (iii)  Employment  of  such  personnel  as  may be
reasonably necessary for the performance of the Partnership's business; and

                              (iv) Distribution,  warehousing, marketing, sales,
information management,  accepting orders for the Partnership's account or under
the Sales Agency Agreement, billing, collection and other services necessary for
the operation of the Partnership's business;

provided,  however, that Services will be on a reasonable efforts basis and that
the General  Partner  shall not be required  to provide  Services  for which the
Costs (as defined  below)  associated  therewith  will not be  reimbursed by the
Partnership.  The Partnership  will not seek another source of Services.  To the
extent the General  Partner is not  capable of  providing  such  Services on the
foregoing  terms,  it shall  cause  Axion to do so on its behalf and, so long as
Axion  does so,  the  General  Partner  will not be deemed in breach  under this
Paragraph 7.8.


                                       19






                    (b)  Reimbursement of Costs. The Partnership shall reimburse
the General  Partner for its costs  (determined  in  accordance  with Exhibit B)
("Costs") of  performing  Services  contemplated  by this  Agreement.  Initially
estimated  Costs for each  Fiscal  Year will be  included  in the  Partnership's
Annual  Operating  and  Capital  Budget for such  year.  A budget for the period
before August 23, 1993 will be submitted to and approved by the Limited Partner;
such budget will include for  reimbursement  certain costs  incurred  before the
date of this Agreement.  For Services Axion  provides,  the General Partner will
pass on to the Partnership  only Axion's Costs and will reimburse Axion for such
Costs out of its reimbursement from the Partnership.

                              (i) The Partnership shall make monthly payments to
the General Partner for estimated Costs to be incurred in the ensuing month. The
Partnership  shall  pay  within 30 days of  invoice  any  Costs  exceeding  such
estimated payments.  Any overpayment shall be deducted from subsequent estimated
payments.

                              (ii) The  reimbursement  of Costs pursuant  hereto
shall include those  expenses  incurred in connection  with the  termination  or
winding down of the  Partnership or the  termination or winding down of Services
to the  Partnership  or  termination  of  General  Partner  or  Axion  employees
performing   Services  ("Termination-Related   Expenses")   including,   without
limitation,  expenses incurred after  termination  pursuant to arrangements made
prior to  termination.  The  General  Partner  will use  reasonable  efforts  to
minimize Termination Related Expenses.

                              (iii)   The  terms  of  any   contract   or  other
arrangement expected to be entered into by the General Partner or Axion that may
result in  Termination-Related  Expenses will be included in the relevant Annual
Operating and Capital Budget; provided,  however, that (A) severance payments to
officers  of the  General  Partner  or Axion  that do not  exceed  $50,000 to an
individual or $200,000 in the aggregate,  (B) severance  payments to non-officer
employees of the General  Partner or Axion that do not exceed amounts paid under
BMS's  severance  policy  to  comparable  employees  and  (C)  any  contract  or
arrangement  that  would not  result  in  reimbursement  of  Termination-Related
Expenses that exceed $50,000 for that contract or  arrangement,  shall be deemed
acceptable whether or not described in the Annual Operating and Capital Budget.

                    (c) If a Partner  purchases the Partnership  Interest of the
other Partner  pursuant to Paragraph 2.2 of this Agreement,  the arrangement set
forth in this  Paragraph  7.8 will  continue in effect for the later of one year
after the Closing or the  expiration  of the Term and the  Extended  Term of the
Sales  Agency  Agreement,  if any, as such terms are defined in the Sales Agency
Agreement on the date of this Agreement, with the purchasing Partner substituted
for the  Partnership  (except that the Services  will not be expanded  beyond or
significantly  changed  from  those  provided  to  the  Partnership  during  the
Partnership Term).

                    (d) The Partnership shall be entitled to have an independent
nationally  recognized certified public accounting firm reasonably acceptable to
the  Partners  and Axion,  audit  during  normal  business  hours,  the relevant
accounting, books and records of the General


                                       20






Partner  and Axion with  respect  to  reimbursed  Costs and  Termination-Related
Expenses provided that such audits shall be conducted  reasonably and limited to
one per year,  that the audited entity is given  reasonable  notice and that the
accounting  firm shall be  obligated to hold the audited  information  and audit
results  in  confidence   except  as  necessary  to  disclose  to  the  Partners
non-compliance with the terms of Paragraph 7.8(b).

                    (e)  Third  Party  Beneficiary.   Axion  is  a  third  party
beneficiary of this Paragraph 7.8.

               7.9 Restrictions on General Partner; Existing Accounts Receivable
and Inventory.  After the effective date of the Sales Agency Agreement,  none of
the General Partner,  Axion or their respective Controlled Affiliates other than
the  Partnership  shall,  during the Partnership  Term,  directly or indirectly,
engage in the Oncology Distribution  Business, or, other than in connection with
clinical trials or research,  distribute any third party oncology product to the
Customer Group,  except through the Partnership;  provided that such restriction
shall not apply in cases where the General  Partner,  Axion or their  respective
Controlled  Affiliates  (as  applicable)  do not have the right to  distribute a
particular product exclusively through the Partnership.  The Partners agree, for
the benefit of Axion, that although not contributed to the Partnership,  (i) the
Partnership  will use its best efforts to collect existing  accounts  receivable
related to the Oncology  Therapeutics Network business and will promptly (but no
later than 5 days after receipt) remit any such amounts  received to Axion,  and
(ii) the Partnership will use its best efforts to sell any Inventory (as defined
below)  held by Axion on the date  hereof and to collect  any  receivables  with
respect to any Inventory so sold,  and will promptly (but in no event later than
5 days after receipt) remit any such amounts  received to Axion, up to an amount
equal to  Axion's  total cost  basis in such  Inventory,  and any excess of such
sales  proceeds  over such cost basis shall be retained  by the  Partnership  in
consideration of such sales. The Partnership will be charged under Paragraph 7.8
for  services  in  connection  with  clause  (ii),  but not clause  (i),  of the
immediately  preceding  sentence.  "Inventory" shall mean the saleable inventory
(including,  without  limitation,  all inventories of  pharmaceutical  products,
active shipments and consigned goods whether located on the premises of Axion or
General Partner, in transit to or from such premises, in storage facilities,  or
otherwise)  owned by Axion on August 22,  1993 (but not  including  products  of
Bristol-Myers Squibb Company or its affiliates).

                                  ARTICLE VIII

                   DISSOLUTION AND LIQUIDATION OF THE PARTNERSHIP

               8.1  Liquidation  Procedures. Upon  expiration of the Partnership
Term or upon the  occurrence of early  termination as described in Paragraph 2.1
above:

                    (a) The affairs of the Partnership shall be wound up and the
Partnership shall be dissolved.

                    (b) The  assets  of the  Partnership  shall  be  applied  to
payment  of  liabilities  of the  Partnership  and paid and  distributed  to the
Partners in the following order:


                                       21






                              (i) to the  creditors  of the  Partnership,  other
than Partners (but including  affiliates of Partners),  in the order of priority
established by law;

                              (ii) to the  Partners,  in  repayment of any loans
made to the Partnership;

                              (iii) to each of the  Partners,  a  payment  of an
amount equal to the Capital Account Prime Rate Amount for such Partner  existing
immediately  prior to the close of the  Partnership's  final  Fiscal Year (which
payment shall not reduce the Capital  Account  balance of the Partner  receiving
such payment); and

                              (iv) to the  Partners,  amounts  equal  to (and in
proportion to) the positive balances in their closing Capital Accounts.  Without
limiting the generality of the foregoing and  notwithstanding  the parenthetical
in Paragraph 3.4,  except as required by law neither the General Partner nor the
Limited  Partner  shall  ever  (either  during  the  Partnership  Term  or  upon
liquidation of the Partnership)  have an obligation under this Agreement to make
any  payments  to the  Partnership  with  respect to a  negative  balance in its
Capital Account or the Capital Account of the other Partner.

                    (c) If  requested  by the  Limited  Partner  or the  General
Partner,  the  Partners  and the  Partnership  shall use their  best  efforts to
distribute  in-kind the assets of the  Partnership  as provided  above such that
each Partner at its election shall receive the non-cash assets that it initially
contributed to the Partnership;  provided, however, that the aggregate amount of
cash and the fair  market  value of other  assets  distributed  to each  Partner
pursuant  to this  Article  VIII shall be in an amount  equal to the amount each
such Partner  would have  received if all of the assets of the  Partnership  had
been sold at their fair market  values for cash and the  proceeds  had been paid
and/or distributed pursuant to clauses (i) through (iv) of Paragraph 8.1(b).

                    (d) The foregoing liquidation procedures shall be subject to
the provisions of Paragraph 2.2 relating to the sale and purchase of a Partner's
Partnership  Interest in certain  circumstances  following the expiration of the
Partnership Term.  Accordingly,  neither dissolution nor liquidation shall occur
during the purchase option exercise period specified in Paragraph 2.2(a) and, if
a Partner's Partnership Interest is being so purchased,  neither dissolution nor
liquidation shall occur prior to the Closing thereof.

               8.2  Final Allocations: Date of Termination.

                    (a) The "Date of  Termination"  shall mean the date on which
the term of the Partnership terminates pursuant to Paragraph 2.1 above.

                    (b) The closing  Capital  Accounts of all the Partners shall
be computed as of the Date of Termination as if the Date of Termination were the
last day of a Fiscal Year, and then adjusted in the following manner:


                                       22






                              (i)  All   assets   and   liabilities   (including
contingent  liabilities  and  including  the  liability to make  payments to the
Partners  in an amount  equal to their  respective  Capital  Account  Prime Rate
Amounts)  of the  Partnership  shall be valued at their  respective  fair market
values as of the Date of Termination.

                              (ii) The resulting net amount of the  unrecognized
gain or loss on the  Partnership's  assets  and  liabilities  as of the  Date of
Termination  shall be deemed to have been recognized  (pursuant to a deemed sale
of the Partnership's assets and deemed payment of the Partnership's liabilities)
and  shall  be  allocated  to  the  Capital  Accounts  of  the  Partners  as Net
Liquidating  Income or Net Liquidating Loss in accordance with the provisions of
Article V. Any income,  gain,  loss or expense  resulting from operations of the
Partnership or other events  occurring after the Date of Termination  shall also
be allocated to the Capital  Accounts of the Partners as Net Liquidating  Income
or Net  Liquidating  Loss in  accordance  with  the  provisions  of  Article  V;
provided, however, that appropriate adjustments shall be made in accordance with
generally accepted accounting  principles so as to avoid taking into account any
item of income,  gain,  loss or expense more than once  pursuant to operation of
this sentence and the immediately preceding sentence.

permitted  to be made after  consultation  between the  General  Partner and the
Limited  Partner and the joint  consent of the  General  Partner and the Limited

                                       26






               10.12 Exculpation.  None of the General  Partner,  its  officers,
directors,  stockholders,  employees,  or affiliates,  the Limited Partner,  its
officers, directors, stockholders,  employees or affiliates, the Chairman of the
Management  Committee or any other officer of the  Partnership or the members of
the Management  Committee  shall be liable to the Partnership or any Partner for
mistakes of judgment, or for action or inaction (unless they constitute a breach
of any term,  covenant or  condition  contained  in this  Agreement or any other
agreement to which any of the foregoing and the  Partnership  are parties or the
gross negligence or willful  misconduct by any such person in the performance of
its obligations under this Agreement or any such agreement) or for losses due to
such mistakes,  action, or inaction,  or to the negligence,  dishonesty,  or bad
faith of any employee,  broker,  or other agent of the Partnership.  The General
Partner, the Limited Partner, the Chairman of the Management Committee and other
officers of the Partnership, and members of the Management Committee may consult
with  counsel and  accountants  in respect of  Partnership  affairs and be fully
protected  and  justified in any action or inaction  that is taken in accordance
with the advice or opinion of such counsel or  accountants,  provided  that they
shall  have been  selected  with  reasonable  care.  Notwithstanding  any of the
foregoing  to the  contrary,  the  provisions  of this  Paragraph  10.12  and of
Paragraph  10.13  hereof  shall not be construed so as to relieve (or attempt to
relieve) any person of any liability by reason of a breach of any term, covenant
or condition  contained in this Agreement or any other agreement to which any of
the foregoing and the Partnership are parties or the gross negligence or willful
misconduct by any such person in the performance of its  obligations  under this
Agreement or any such other  agreement or to the extent (but only to the extent)
that such liability may not be waived, modified or limited under applicable law,
but shall be construed so as to  effectuate  the  provisions  of this  Paragraph
10.12 and of Paragraph 10.13 to the fullest extent permitted by law.

               10.13 Indemnification.  The  Partnership agrees to indemnify, out
of the assets of the  Partnership  only, the  General Partner and its affiliates
(and any  officer,  director,  stockholder or employee of the General Partner or
any of its affiliates), its agents, the  Chairman of the  Management  Committee,
any other officer of the  Partnership  and  members of the  Management Committee
and  the  Limited  Partner  and  its  affiliates  (and  any  officer,  director,
stockholder or employee of the Limited  Partner or any of its affiliates) to the
fullest extent permitted by law and to save and hold them  harmless  from and in
respect of all (a) fees (including  attorneys' fees),  costs,  and expenses paid
in connection with or resulting from any  claim,  action,  or demand against the
General Partner, the Limited  Partner,  any  officer,  director, stockholder  or
employee of the General  Partner  or  the  Limited  Partner, the Chairman of the
Management Committee,  any member of the Management  Committee,  the Partnership
(or any of its officers), or any of their agents that arise out of or in any way
relate to the Partnership,  its properties,  business, or affairs, as such fees,
costs and expenses are incurred, and  (b) such claims,  actions, and demands and
any losses or damages  resulting  from  payments to  third parties on account of
such  claims,  actions, and  demands,  including  amounts  paid in settlement or
compromise of any such  claim, action or  demand and  (c) solely with respect to
the General Partner, any liability for penalties,  fines or the like owed to any
taxing  jurisdiction resulting  from the filing of a tax return or the taking of
(or failure to take) any  other  action,  in each  case  by the  General Partner
on  behalf  of the Partnership and in  compliance with the  determination of the
Arbitrator  pursuant to Paragraph 10.17 (but only




                                       27






to the extent such liability is incurred by the General  Partner in its capacity
as general partner of the Partnership);  provided,  however, that this indemnity
shall not extend  with  respect to any such  person (or any  officer,  director,
stockholder  or  employee  thereof)  to (i) any breach by any such person of any
term,  covenant or condition  contained in this Agreement or (ii) from the gross
negligence or willful  misconduct by any such person in the  performance  of its
obligations  under this  Agreement or (iii) any  obligation  of or breach by any
such person under another agreement it has with the Partnership or any liability
or expense of the Partnership  arising  therefrom or (iv) failure to comply with
the determination of the Arbitrator pursuant to Paragraph 10.17. The indemnities
provided by this paragraph  will survive the  termination or dissolution of this
Agreement  for  any  reason,  and  will  survive  any  Transfer  of a  Partner's
Partnership  Interest with respect to the period during which such  transferring
Partner was deemed a Partner under the terms of this Agreement.  Notwithstanding
the  foregoing  provisions  of this  Paragraph  10.13,  in no event will  either
Partner be  indemnified  hereunder  for  liability  to any  taxing  jurisdiction
(including,  without  limitation,  liability for taxes,  penalties and interest)
resulting directly or indirectly from the manner in which such Partner reflected
the operations of the Partnership on such Partner's own tax returns.

               10.14 Tax  Matters  Partner.  The  General  Partner  shall be the
Partnership's Tax Matters Partner ("TMP").  The TMP shall employ experienced tax
advisors  to  represent  the   Partnership  in  connection  with  any  audit  or
investigation of the Partnership by the Internal Revenue Service ("IRS"), or any
state,  local, or foreign taxing authority and in connection with all subsequent
administrative   and  judicial   proceedings   arising  out  of  such  audit  or
investigation.  The fees and expenses of such, and all other reasonable expenses
incurred by the TMP in serving as the TMP,  shall be  Partnership  expenses  and
shall be paid by the Partnership. Notwithstanding the foregoing, it shall be the
responsibility  of the  General  Partner and of the  Limited  Partner,  at their
expense,   to  employ  tax  advisors  to  represent  their  respective  separate
interests.  If the TMP is  required  by law or  regulation  to  incur  fees  and
expenses in connection with tax matters not affecting each of the Partners, then
the TMP may,  with the,  Special  Approval of the  Management  Committee  (which
approval shall not be unreasonably withheld),  seek reimbursement from or charge
such fees and expenses to the Capital Accounts of those Partners on whose behalf
such fees and expenses  were  incurred.  The TMP shall keep the Limited  Partner
informed of all administrative and judicial proceedings,  as required by Section
6223(g) of the Code, shall provide any other information as reasonably requested
by  the  Limited   Partner  with  respect  to  any  audit,   investigation   and
administrative or judicial  proceeding,  and shall furnish a copy of each notice
or other  communication  received by the TMP from the IRS or any state, local or
foreign  taxing  authority,  except such notices or  communications  as are sent
directly to the Limited Partner by the IRS or such other taxing  authority.  The
TMP agrees that,  except as otherwise  required by applicable law, in conducting
any such audit,  investigation and administrative or judicial proceeding, (a) it
shall consult with and act upon any  instructions  given by the Limited  Partner
and (b) if the TMP disagrees with any such instructions, the actions to be taken
by the TMP shall be determined pursuant to the provisions of Paragraph 10.17. To
the fullest extent permitted by law, out of the assets of the Partnership  only,
the  Partnership  agrees to  indemnify  the TMP and its agents and save and hold
them  harmless,  from and in  respect  to all (i)  reasonable  fees,  costs  and
expenses in  connection  with or  resulting  from any claim,  action,  or demand



                                       28






against the TMP, the General Partner or the Partnership  that arise out of or in
any way relate to the TMP's status as TMP for the Partnership, and (ii) all such
claims,  actions,  and  demands and any losses or damages  therefrom,  including
amounts paid in settlement or compromise of any such claim,  action,  or demand;
provided that this indemnity shall not extend to conduct by the TMP adjudged (A)
to be a breach by the TMP of any term,  covenant or condition  contained in this
Agreement,  unless the conduct  causing  such breach was  required by any law or
regulation  applicable  to the General  Partner or (B) to have resulted from the
gross  negligence  or  willful  misconduct  of  the  TMP  with  respect  to  its
obligations under this Agreement.  The indemnity provided by this paragraph will
survive  the  termination  or  dissolution  of this  Agreement  for any  reason.
Notwithstanding  anything in this  Agreement to the contrary,  without the joint
consent of the General  Partner and the Limited  Partner,  which  consent may be
denied in either  Partner's  sole  discretion,  the TMP (a) shall not extend any
applicable  statute of limitations  for the imposition of any tax, (b) shall not
settle or compromise any claim by the IRS or any state,  local or foreign taxing
authority,  (c) protest or appeal any administrative or proposed  administrative
action  by the IRS or any  state,  local  or  foreign  taxing  authority  or (d)
institute  in court  any  proceeding  or appeal  any  judgment  from a  judicial
proceeding,  in each  case to the  extent  such  claim,  action,  proceeding  or
judgment  relates to taxes  imposed on the  Partnership  or any Partner.  If the
General Partner and the Limited Partner disagree as to any action to be taken by
the TMP  (other  than any action  required  to be taken by the TMP  pursuant  to
applicable  law) or disagree as to any other matter  relating to this  Paragraph
10.14 (including,  without limitation,  the interpretation or application of any
law), then actions to be taken by the TMP, or such other disagreement,  shall be
resolved pursuant to the provisions of Paragraph 10.17.

               10.15 Taxation as Partnership.  Each of  the  General Partner and
the  Limited Partner  agree to use its  best  efforts to avoid taking any action
that would cause the  Partnership  to be classified  as other than a partnership
for federal,  and applicable  state,  local and foreign  income (and  franchise)
tax purposes.

               10.16 Authorization.  All  corporate  action  on the part of each
party hereto  necessary  for the  authorization,  execution and delivery of this
Agreement and the performance of all obligations  hereunder has been taken.  The
persons executing this Agreement have due power and authority to so execute this
Agreement.

               10.17  Arbitration;  Cooperation.  If the General Partner and the
Limited  Partner  disagree  as to the  making of any tax  election,  the form or
content  of any tax  return  proposed  to be  filed by the  Partnership,  or the
resolution  of any other issue or the making of any other  decision  relating to
taxes, the Partners shall promptly submit such disagreement to a mutually agreed
upon  arbitrator  (the  Arbitrator),  who shall be a partner of a law firm, or a
partner  of a "big six"  accounting  firm,  in either  case  expert in income or
franchise tax matters, as applicable,  for prompt,  binding  resolution.  In the
event the parties are unable to mutually agree upon the Arbitrator,  they hereby
agree that the head of the Tax Section of the  American  Institute  of Certified
Public Accountants shall select the Arbitrator. All fees of the Arbitrator shall
be paid one half by the General Partner and one half by the Limited Partner. The
Arbitrator, once initially selected, shall continue to serve with respect to any
future  disagreement  between the Partners subject to this Paragraph 10.17 until
such time as the Partners jointly decide to dismiss such


                                       29






arbitrator.  In rendering his determination,  the Arbitrator shall have complete
discretion and shall not be required to choose an  alternative  advocated by the
General  Partner  or  Limited  Partner;  provided,  however,  that in making his
determination,  the Arbitrator shall resolve to take such course of action as he
believes will most likely minimize the aggregate tax liabilities of the Partners
and their Affiliates without unduly benefiting or harming any particular Partner
or its Affiliates.  Each of the Partners (and their respective Affiliates) shall
cooperate with each other (and with the Arbitrator) in the implementation of any

                                   ARTICLE XII

                      MISCELLANEOUS TAX COMPLIANCE PROVISIONS

               12.1 Income Tax Allocations. To the maximum  extent  permitted by
the  Code  and  the  rules  and  Treasury  Regulations  promulgated  thereunder,
Partnership  income,  gain, loss,  deduction,  or credit for income tax purposes
shall be allocated in a manner that fairly and accurately  reflects the economic
arrangement among the Partners pursuant to this Agreement.

                    (a) The General  Partner  shall  prepare  the  Partnership's
federal,  state,  local and foreign (and  franchise) tax returns (and elections)
and shall  transmit  a copy of any such  return  (or  election)  to the  Limited
Partner for the Limited Partner's review of such return (or election) forty-five
(45) days prior to the filing of such  return (or  election)  and shall not file
any such return (or election) without the Limited Partner's consent.  If, within
thirty (30) days of receipt of such return (or election)  from the  Partnership,
the  Limited  Partner  does not notify the  General  Partner of any  recommended
changes  to such  return  (or  election)  the  Limited  Partner  shall have been
conclusively  presumed  to have  consented  to the  filing  of such  return  (or
election)  as  received by it. The General  Partner  shall  timely file any such
return (or election) along with the amount of tax shown to be due on such return
(or election) with the appropriate taxing jurisdiction.


                                       30






                    (b)  Notwithstanding  anything in  Paragraph  12.1(a) to the
contrary,  the General  Partner agrees to consult with the Limited  Partner with
respect  to the  preparation  of the  Partnership's  federal,  state,  local and
foreign  income (and  franchise) tax returns and  elections,  including  without
limitation, (a) the calculation of the Partnership's taxable income for federal,
state,  local and  foreign  income  (and  franchise)  tax  purposes  and (b) the
allocation to the Partners of the Partnership's  income,  gain, loss,  deduction
and credit for federal,  state,  local and foreign  income (and  franchise)  tax
purposes.  In the event that the  Partners  do not agree on any aspect of any of
the Partnership's  federal,  state, local and foreign income (and franchise) tax
returns or elections  (including  the failure to adopt any  recommended  changes
made by the Limited  Partner) or on a calculation  or allocation as described in
clauses (a) and (b) of the immediately preceding sentence the action to be taken
with respect to such aspect or  calculation  or  allocation  shall be determined
pursuant to the provisions of Paragraph 10.17.

                    (c)  Notwithstanding   the  foregoing   provisions  of  this
Paragraph  12.1,  in the event any tax election  must be made sooner than ninety
(90) days after the event that triggered the  availability of the election (such
period  of  time  is  hereafter  referred  to as  the  "Election  Period"),  the
forty-five  (45) day period referred to in Paragraph 12(a) shall be reduced to a
period equal to one-half  (1/2) of the  Election  Period and the thirty (30) day
period  referred to in Paragraph  12.1(a)  shall be reduced to a period equal to
one-third (1/3) of the Election Period.

               12.2 Withholding. The Partnership  shall at all times be entitled
to make  payments  with respect to any Partner in amounts  required to discharge
any  obligation  of  the  Partnership  to  withhold  or  make  payments  to  any
governmental  authority  with  respect  to any  federal,  state,  local or other
jurisdictional  tax  liability  of such  Partner  arising  as a  result  of such
Partner's Partnership Interest.  The General Partner shall cause the Partnership
to pay the amount of any such  withholding  or other  payments to the applicable
government  authority  and shall supply each  Partner with a receipt  evidencing
such  payment.  To the extent each such payment  satisfies an  obligation of the
Partnership to withhold with respect to any  distribution  to a Partner on which
the  Partnership  did not  withhold or with respect to any  Partner's  allocable
share of the income of the Partnership,  each such payment shall be deemed to be
a loan by the  Partnership  to such  Partner  (which  loan shall be deemed to be
immediately  due and  payable)  and shall not be deemed a  distribution  to such
Partner.  The amount of such payments  made with respect to such  Partner,  plus
interest,  on each such  amount  from the date of each such  payment  until such
amount is repaid to the  Partnership  at an interest rate per annum equal to the
Prime Rate,  shall be promptly  repaid to the  Partnership  by the Partner.  The
Partnership  may, in its discretion,  defer making  distributions to any Partner
that owes amounts to the Partnership  pursuant to this Paragraph 12.2 until such
amounts are paid to the Partnership (or, alternatively,  may deduct such amounts
from amounts  distributable by the Partnership to such Partner and such deducted
amounts will be treated as having been repaid) and may in addition  exercise any
other  rights of a creditor on behalf of the  Partnership  with  respect to such
amounts.

               12.3 Other Tax Returns. Except as provided in Section 3(f) of the
Sales Agency Agreement and in Paragraph  12.1(a),  (i) the General Partner shall
prepare any  report,  return or  statement  (collectively  a  "report")  that is
required  to be  filed  by the  Partnership  with  respect  to any  sales,  use,
property,  license or rental taxes and any other taxes and shall transmit to




                                       31






the Limited Partner a copy of any such report for the Limited  Partner's  review
ten (10) days  prior to the  filing of such  report  and shall not file any such
report without the Limited  Partner's  prior consent;  (ii) if, within seven (7)
days of receipt of such report from the  Partnership,  the Limited  Partner does
not notify the  General  Partner of any  recommended  changes to such report the
Limited Partner shall have been  conclusively  presumed to have consented to the
filing of such report as received by it; (iii) the General  Partner shall timely
file any such report along with the amount of tax shown to be due on such report
with the  appropriate  taxing  jurisdiction  and (iv) the General  Partner shall
transmit a copy of any such report to the Limited  Partner on the date of filing
of any such report or promptly thereafter. In the event that the Partners do not
agree on any aspect of any report  described in this Paragraph  12.3, the action
to be taken with  respect to such  report  shall be  determined  pursuant to the
provisions of Paragraph 10.17.
