acquire an  additional  vested  interest  in the Joint  Venture  pursuant to the
provisions of Section 3.4, 3.5, or 3.6 hereof, as the case may be, 



                                      -5-


shall have no right to acquire an  interest  in Brand Name LLC  pursuant  to the

              Review  Committee.  For this  purpose,  the  members of the Review
              Committee  appointed by Chalone  shall have, in the  aggregate,  a
              voting interest on matters subject to Review Committee decision or
              approval  equal  to  the  vested  interest  in the  Joint  Venture
              actually paid for by Chalone pursuant to the foregoing  provisions
              of this  Article III of the Joint  Venture  Agreement  (not taking
              into account,  in the amount considered paid for by Chalone,  that
              portion  of the  Deposit  forfeited  by  Chalone  pursuant  to the
              provisions  of Section 3.9 hereof),  and the members of the Review
              Committee  appointed by Paragon  shall have, in the  aggregate,  a
              voting  interest on matters subject to the decision or approval of
              the Review  Committee  equal to 100% minus the voting  interest of
              the  members  of  the  Review  Committee   appointed  by  Chalone,
              determined as aforesaid.


                           (ii) Notice of regular  and  special  meetings of the
              Review  Committee shall be provided as set forth in Section 8.2(d)
              and (e) of the 1991 Joint Venture Agreement.


                           (iii)  The  attendance  at a  meeting  of the  Review
              Committee of one or more members possessing a majority in interest
              of the voting  power of the Review  Committee  shall  constitute a
              quorum of the Committee for the transaction of business.


                                      -6-


                           (iv) The transaction of any meeting of the Committee,
              however called and noticed and wherever held, shall be as valid as
              though had at a meeting duly held after  regular call or notice if
              a quorum be present and if,  either  before or after the  meeting,
              the members  possessing a majority in interest of the voting power
              of the members of the Review  Committee  sign a written  waiver of
              notice, a consent to holding such a meeting, or an approval of the
              minutes thereof. All such waivers, consents, or approvals shall be
              filed  with the  records  of the  Committee  and made  part of the
              minutes of the meeting.


                           (v) Any action  required or  permitted to be taken by
              the Review  Committee  may be taken  without a meeting and without
              prior notice if all members of the Committee shall individually or
              collectively  consent in writing to such  action.  Such consent or
              consents  shall have the same  effect as a  unanimous  vote of the
              Committee  and shall be filed with the minutes of the  proceedings
              of the Committee.


                           (vi) The members of the Committee may  participate in
              meetings of the  Committee as  permitted by Section  8.2(g) of the
              1991 Joint Venture Agreement.


                           (vii) The Review Committee shall possess the power to
              hire and discharge the winemaker of the Winery:  the provisions of
              Section  8.1(c)  of the  Joint  Venture  Agreement  shall be of no
              further  force or effect,  and  Chalone  shall no longer  have the
              power,  granted by Section 8.1(c) of the Joint Venture  Agreement,
              to force a discharge  of the general  manager of the Winery or, if
              there is no general  manager of the Winery,  the  winemaker of the
              Winery by an expression of 'no confidence.'


         3.10     Revision of Article VII of Joint Venture Agreement


                  (a) In the event that  Chalone  makes a No  Payment  Election,
then and in such  event,  from and after the  effective  date of the No  Payment
Election,  all  distributions  of Available Cash made pursuant to Section 7.1 of
the Joint Venture  Agreement shall be allocated and distributed to Chalone in an
amount equal to the vested  interest in the Joint  Venture  actually paid for by
Chalone  pursuant to the  foregoing  provisions of this Article III of the Joint
Venture Agreement (not taking into account, in the amount considered paid for by
Chalone,  that  portion of the  Deposit  forfeited  by Chalone  pursuant  to the
provisions  of Section 3.9  hereof),  with the balance of the  distributions  of
Available Cash allocated and distributed to Paragon. The relative percentages of
distributions of Available Cash, 



                                      -7-


determined as aforesaid,  shall also be used in allocating any "remaining  gain"
to be allocated to the Joint  Venture  Partners  pursuant to the  provisions  of
Section  7.2(b) of the Joint Venture  Agreement,  and in allocating  between the
Partners all income,  gains,  losses,  deductions,  and  credits,  and each item
thereof,  to be allocated  between the Joint  Venture  Partners  pursuant to the
provisions of Section 7.2(c) of the Joint Venture Agreement."


4.       Amendments to Article IV of the 1991 Joint Venture Agreement (Chalone's
         Purchase  of a  One-half  Interest  in the  Winery  and  the  Expansion
         Thereof)


         Article IV of the 1991 Joint Venture Agreement is hereby amended in the
following respects and in the following respects only.


         Section  4.7 is hereby  added to Article IV to read in its  entirety as
follows:


         4.7      Amended Ground Lease


                  The Joint Venture  shall,  concurrently  with this  Amendment,
enter into an Amended  Ground Lease with Paragon,  substantially  in the form of
Exhibit B hereto.  Pursuant to the Amended Ground Lease, the Joint Venture shall
lease additional  acreage from Paragon,  and shall pay increased rent to Paragon
under the  Amended  Ground  Lease  equal to the rent called for under the Ground
Lease for any applicable period multiplied by a fraction, the numerator of which
is the acreage included in the Amended Ground Lease and the denominator of which
is the acreage included in the Ground Lease."





5.       Amendments to Article V of the 1991 Joint Venture  Agreement (Supply of
         Grapes by Paragon to the Joint Venture)


         Article V of the 1991 Joint Venture  Agreement is hereby amended in its
entirety to read as follows:


         5.1      Revision of Grape Purchase Agreement


                  (a) Paragon and the Joint Venture shall, concurrently with the
execution of this  Amendment,  enter into an Amended and Restated Grape Purchase
Agreement, substantially in the form of Exhibit A hereto. The Joint Venture may,
upon Review  Committee  approval,  purchase and resell,  or vint as bulk wine, a
portion  of the  grapes  required  to be  purchased  by the Joint  Venture  from
Paragon.


                  (b) The  obligation  of  Paragon  to use its  best  reasonable
efforts to supply the Joint  Venture  with  Chardonnay  grapes  pursuant  to the
Amended Grape Purchase  



                                      -8-


Agreement shall be subject to Paragon's  obligations to customers other than the
Joint Venture (as said  customers may be replaced by new customers  from time to
time). By way of illustration and not limitation,  should weather  conditions or
other circumstances  beyond Paragon's control limit the harvest in any one year,
then the grapes sold to the Joint Venture by Paragon  would be reduced  pro-rata
based  upon the  Joint  Venture's  share of the  year's  projected  harvest,  as
determined in good faith by Paragon.  It is agreed that because of the fact that
different  customers  of Paragon may  purchase  grapes for delivery at different
times  during  the  harvest,  any good faith  allocation  made by Paragon of its
harvest  among its  customers on or prior to September 1st of each year shall be
binding and conclusive upon the Joint Venture.


                  (c) Other than as expressly contemplated by Article XI hereof,
by the  Amended  Grape  Purchase  Agreement,  or as  expressly  provided  by the
business plan adopted  pursuant to the provisions of Section  8.5(a) hereof,  as
the same may be amended from time to time, or as permitted by Paragon's  written
consent,  the Joint Venture shall not purchase bulk wine or vint grapes from any
source other than Paragon."


6.       Amendments to Article VI of the 1991 Joint Venture  Agreement  (License
         of Brand Name)


         Article VI of the 1991 Joint Venture Agreement is hereby amended in its
entirety to read as follows:


         6.1      Ownership of the Brand Name


                  The brand name "Edna Valley  Vineyard"  (the "Brand  Name") is
currently  the  property  of  Paragon.  The Brand Name is  licensed to the Joint
Venture  pursuant to that certain  License  Agreement by and between Paragon and
the Joint  Venture,  dated as of  January  1, 1991  (the  "License  Agreement").
Concurrently with the execution of this Amendment, the Joint Venture and Paragon
shall  enter  into a  Revised  License  Agreement  substantially  in the form of
Exhibit C-1 hereto. On December 12, 1996, Paragon organized a California limited
liability  company  with the name "Edna Valley  Brand Name,  LLC"  (hereinafter,
"Brand  Name  LLC")  pursuant  to  Articles  of  Organization  and an  Operating
Agreement  in the form of C-2 and C-3 hereto.  The two members of Brand Name LLC
are Paragon and James H. Niven.  Mr.  Niven shall  withdraw as a member of Brand
Name LLC at such time as Chalone acquires an interest in and becomes a member of
Brand Name LLC pursuant to the  provisions  of Section 3.7 of the Joint  Venture
Agreement.  Concurrently  with the  execution of this  Amendment,  Paragon shall
contribute  all of its right,  title,  and  interest in and to the Brand Name to
Brand Name LLC, in exchange for substantially all of the membership interests in
Brand Name LLC. Concurrently with the 


                                      -9-


execution of this Amendment,  Paragon shall assign all of its right,  title, and
interest as licensor under the Revised License  Agreement to Brand Name LLC, and
Brand Name LLC shall assume all rights and obligations of Paragon,  as licensor,
under the Revised  License  Agreement  pursuant to an Assignment  and Assumption
Agreement,  substantially in the form of Exhibit C-4 hereto.  No member of Brand
Name LLC may transfer  its interest in Brand Name LLC without the prior  written
consent of the other member,  which consent may be withheld in the member's sole
and absolute discretion; provided, however, that the aforesaid restriction shall
not prevent a transfer of the interest in Brand Name LLC by a member pursuant to
a Change in Control of the  member,  as the term Change in Control is defined by
the Joint Venture Agreement.


         6.2      Sharing of Proceeds From Any Sale of the Brand Name


                  (a)  Should  Brand  Name  LLC,  during  the term of the  Joint
Venture  Agreement,  sell its rights to the Brand Name, whether by themselves or
as a part of the sale by Paragon of the Vineyard, and, at the time of such sale,
Chalone has not yet exercised the option granted to it by the Option to Purchase
Membership  Interests,  then and in such event Paragon (on its own behalf and on
behalf of Brand Name LLC)  agrees that  Chalone  shall be entitled to 50% of the
proceeds from any such sale attributable to the Brand Name;  provided,  however,
that  Chalone's  entitlement  to 50% of the proceeds as aforesaid is conditional
upon Chalone's  having timely made all payments called for by Sections 3.4, 3.5,
and 3.6 hereof theretofore falling due, and upon its prompt payment of such sums
as remain to be paid under said Sections in full to Paragon;  provided  further,
however,  that  Chalone's  entitlement  to 50% of the  proceeds as  aforesaid is
further conditioned upon Chalone's purchasing a 50% membership in Brand Name LLC
pursuant to the  provisions  of 3.7 hereof.  In addition,  if Chalone has timely
made all payments  called for by Sections 3.4, 3.5, and 3.6 hereof,  theretofore
falling due, any sale, assignment,  encumbrance, or other transfer by Paragon of
its rights to the Brand Name occurring  prior to the time that Chalone becomes a
members of Brand Name LLC shall  require the consent of Chalone,  which  consent
shall not be unreasonably withheld or delayed.


                  (b) If, at the time of sale, Chalone has not yet exercised the
option  granted to it by the Option to Purchase  Membership  Interests,  and the
sale of the Brand Name by Brand Name LLC is to a third party not Affiliated with
Paragon,  and such sale consists only of the Brand Name,  then the proceeds from
sale of the Brand Name shall be  conclusively  established  by the  agreement of
sale entered  into by Brand Name LLC and said third party.  If the Brand Name is
sold as part of other assets to a third party not Affiliated  with Paragon,  and
the  agreement  of sale does not allocate  that  portion of the  


                                      -10-


purchase price  allocable to the Brand Name,  then and in such event Paragon and
Chalone  shall  attempt to apportion  the  purchase  price of the assets sold by
Paragon  between the Brand Name and the other  assets  sold.  If the parties are
unable to agree on an allocation,  then the proceeds of the sale attributable to
the Brand Name shall be determined by arbitration  pursuant to the provisions of
Article  XVIII hereof.  If the Agreement of Sale does  apportion the proceeds of
sale to the Brand Name and the other  assets sold by Paragon to the third party,
then said allocation shall conclusively  establish the proceeds from sale of the
Brand Name for  purposes of this Section 6.2. If Brand Name LLC sells its rights
to the Brand Name to a party  Affiliated  with Paragon,  and Paragon and Chalone
are not able to agree upon the portion of the proceeds from sale attributable to
the Brand Name, then the proceeds from sale thereof shall likewise be determined
by  arbitration  pursuant to the  provisions of Article XVIII hereof.  Chalone's
rights  under this  Section 6.2 shall  terminate  and be of no further  force or
effect upon the  occurrence  of any Event of Default  committed  by it under the
provisions  of Article  XVII  hereof or any  election by Chalone not to make any
payment called for by Sections 3.4, 3.5, 3.6, or 3.7 hereof and the continuation
of any such  election  for a period of five (5) or more days beyond the due date
of any payment called for by any such Section.


         6.3      Purchase  of Brand Name by Joint  Venture in the Event of Sale
                  of the Assets of the Joint Venture


                  Should both of the Joint Venture Partners agree to sell all or
substantially  all of the assets of the Joint  Venture,  then and in such event,
pursuant to the Revised License Agreement with Brand Name LLC, the Joint Venture
shall have the  option,  but not the  obligation,  to  acquire  Brand Name LLC's
entire interest in the Brand Name for a payment of Four Hundred Thousand Dollars
($400,000) to Brand Name LLC. The foregoing  option shall not be  exercisable by
the Joint  Venture  unless and until  Chalone  has made all  payments to Paragon
called for by Sections 3.4, 3.5, 3.6, and 3.7 hereof. The payment of $400,000 by
the Joint Venture to Brand Name LLC shall be made  concurrently with the closing
of the sale of all or  substantially  all of the  assets of the  Joint  Venture.
Other than as  contemplated by this Section 6.3, the Joint Venture shall have no
right to acquire  the  interest  of Brand Name LLC as licensor of the Brand Name
under the Revised License Agreement."


7.       Amendments  to  Article  VIII  of  the  1991  Joint  Venture  Agreement
         (Management of the Joint Venture)


         Article VIII of the 1991 Joint Venture  Agreement is hereby  amended in
the following respects, and in the following respects only.


                                      -11-


         Section  8.1(b)(iv)  is  hereby  amended  in its  entirety  to  read as
follows:


                  "(iv)  Select or  discharge  the  winemaker  of the  Winery or
         select or discharge the general manager of the Winery;"

                  "(c) The selection of a winemaker  and any general  manager of
         the Winery shall be made on the  recommendation  of the Managing  Joint
         Venture  Partner and  approved by the Review  Committee  as provided by
         subsection  (b)(iv)  above;  any dispute  regarding  the selection of a
         winemaker  or the  general  manager  of the  Winery may not be taken to
         arbitration. Either Joint Venture Partner may, at any time, in its sole
         discretion,  by notice to the other Joint Venture Partner,  express "no
         confidence"  in the  general  manager  of the Winery or, if there is no
         general  manager  of  the  Winery,  in the  winemaker.  Upon  any  such
         expression of no confidence,  the Review  Committee shall promptly meet
         to discuss the no confidence  notice of the Joint Venture Partner.  If,
         after such meeting,  the Joint Venture Partner  continues to express no
         confidence  in the general  manager or  winemaker,  as the case may be,
         then the Joint Venture  shall proceed to discharge the general  manager
         or the winemaker, as the case may be. In such event, the Managing Joint
         Venture  Partner  shall proceed to search for and recommend a successor
         to the Review  Committee.  The officer of the  Managing  Joint  Venture
         Partner  to whom the  general  manager of the Winery or, if there is no
         general manager,  the winemaker of the Winery,  shall report to and act
         under the  supervision  of shall be as designated  from time to time by
         the Review  Committee.  If the Review  Committee  cannot agree upon the
         selection  of such  officer,  then the  individual  to whom the general
         manager or the  winemaker,  as the case may be, shall report to and act
         under  the  supervision  of  shall  be  the  Managing  Director  of the
         Committee  as  determined  under  Section  8.3(d) of the Joint  Venture
         Agreement."


         Section 8.3(d) is hereby amended in its entirety to read as follows:


                  "(d) The Managing Director of the Committee shall be W. Philip
         Woodward,  so long as Mr.  Woodward  serves as an  officer  of  Chalone
         primarily  responsible for the conduct of Chalone's day-to-day business
         and as long as Chalone  remains the Managing  Joint Venture  Partner of
         the  Joint  Venture.  In the  event  that  Mr.  Woodward  is no  longer
         qualified or is unable to serve, at a point in time when Chalone is the
         Managing Joint Venture Partner of 



                                      -12-


         the Joint  Venture,  then the  position  of  Managing  Director  of the
         Committee shall be filled as follows:  Chalone shall, by written notice
         to Paragon,  identify  three  candidates  each of whom is an officer or
         director  of  Chalone  and  each  of  whom,  by  reason  of  his or her
         education, training, experience, and knowledge of the wine business and
         the  business of the Joint  Venture,  is qualified to serve as Managing
         Director  of the  Committee.  The  written  notice  shall  specify,  in
         reasonable  detail,  the  qualifications  of each candidate to serve as
         Managing Director of the Committee.  Within thirty (30) days of receipt
         of the aforesaid notice from Chalone,  Paragon shall notify Chalone, in
         writing,  of its  agreement  to  the  selection  of  one  of the  three
         candidates  identified by Chalone to serve as Managing  Director of the
         Committee,  and such person shall thereafter serve as Managing Director
         of the  Committee  pursuant  to the terms and  provisions  of the Joint
         Venture Agreement.  If Paragon does not notify Chalone,  in writing, of
         its  agreement  to  the  selection  of  one  of  the  three  candidates
         identified by Chalone  within thirty (30) days of Paragon's  receipt of
         the notice from  Chalone as  aforesaid,  then Chalone may, by notice to
         Paragon,  select one of the three  candidates  identified by Chalone as
         the  Managing  Director  of the  Committee.  In the event that  Chalone
         ceases to be the Managing  Joint Venture  Partner of the Joint Venture,
         then the position of Managing Director of the Committee shall forthwith
         become vacant and the individual  who shall serve as Managing  Director
         of the  Committee  shall be  determined  by the Review  Committee.  The
         Managing Director of the Committee shall preside at all meetings of the
         Committee  and shall  exercise and perform such other powers and duties
         as may from time to time be assigned to him by the Committee."


         Section  8.3(f) is hereby added to the Joint Venture  Agreement to read
in its entirety as follows:


                  "(f) The  general  manager  of the  Winery  or, if there is no
         general  manager of the Winery,  the  winemaker  of the  Winery,  shall
         attend  all  meetings  of the  Review  Committee  for  the  purpose  of
         reporting on the business and activities of the Joint Venture under his
         or her supervision."


         Section 8.5(a) is hereby amended in its entirety to read as follows:


                  "(a) As long as it  remains  a Joint  Venture  Partner  of the
         Joint Venture, and subject to the provisions of Section 3.9 and Article
         XVII of the Joint Venture  Agreement  and of this Section 8.5,  Chalone
         shall serve as the Managing Joint Venture Partner of the Joint Venture.
         Chalone may be removed 



                                      -13-


         at any time as Managing Joint Venture Partner by the Review  Committee.
         In  addition,  should  there  occur at any time a Change in  Control of
         Chalone,  then and in such event the position of Managing Joint Venture
         Partner shall forthwith  become vacant,  and the Review Committee shall
         select its  successor;  provided,  however,  that,  if at the time of a
         Change in Control of Chalone, there has previously occurred a Change in
         Control of Paragon, then and in such event the position of the Managing
         Joint  Venture  Partner  shall not become  vacant,  and  Chalone  shall
         continue as Managing Joint Venture Partner, notwithstanding a Change in
         Control of Chalone; provided further, however, that notwithstanding any
         Change in Control of Chalone,  if the following  procedure is followed,
         then the position of Managing  Joint  Venture  Partner shall not become
         vacant, and Chalone shall continue as Managing Joint Venture Partner of
         the  Joint  Venture,  to  serve  as  such  pursuant  to the  terms  and
         provisions of the Joint Venture Agreement:


                  (i)  Attached  hereto as Exhibit D is a business  plan for the
         Joint  Venture  for the three  years  ending  December  31,  1999.  The
         business plan establishes  objectives for the Joint Venture in terms of
         case sales, by category of varietal wine to be produced and marketed by
         the Joint Venture,  pricing,  gross margins, and related matters.  Each
         year  thereafter,  on or before  December  31 of each year,  the Review
         Committee shall revise and update the business plan. For the year ended
         December  31, 1997,  the business  plan shall be revised to address the
         three years ended  December 31, 2000,  and for the year ended  December
         31, 1998, the business plan shall be expanded to address the four years
         ended December 31, 2002. The business plan shall be updated  thereafter
         to address the four years  following  adoption  of the  revision by the
         Review Committee.


                  (ii) A Change in Control  of  Chalone  shall not result in the
         position of Managing Joint Venture  Partner  becoming  vacant if, by no
         later than  thirty  (30) days after the  effective  date of a Change in
         Control  of  Chalone,   the  Person(s)  acquiring  control  of  Chalone
         (hereinafter,  the  "Acquiror")  provides  written  notice  to  Paragon
         specifying  each of the  following:  (A) that the  Acquiror  adopts and
         agrees to the terms and  provisions  of the business plan most recently
         adopted by the Review Committee prior to the effective date of a Change
         in Control of Chalone (hereinafter, the "Benchmark Plan"); and (B) that
         the  Acquiror  agrees  to take no  steps to  cause  Chalone  not to use
         Chalone's best reasonable efforts, as Managing Joint Venture Partner of
         the Joint Venture,  to implement  fully the terms and provisions of the
         Benchmark Plan.


                                      -14-


              In the event that there  occurs at any time a Change in Control of
              Chalone,  and the  Acquiror  does not provide  the written  notice
              called for by  paragraph  (ii)  above,  then and in such event the
              position of Managing Joint Venture Partner shall forthwith  become
              vacant,  and the Review  Committee shall select its successor.  If
              the members of the Review  Committee cannot agree upon a successor
              to the  Managing  Joint  Venture  Partner or cannot agree upon the
              duties and  responsibilities of the successor,  or if the position
              of Managing  Joint Venture  Partner  remains vacant for 60 or more
              days after a Change in Control of Chalone,  then and in such event
              Paragon (if it is still then a Joint Venture Partner and is not in
              default under this Agreement) shall have the right to appoint,  in
              its sole  discretion,  the  successor  (which may be  Paragon)  to
              Chalone as Managing Joint Venture  Partner,  which successor shall
              assume all duties and  responsibilities  of Managing Joint Venture
              Partner of the Joint Venture,  including,  without limitation, the
              right and power,  upon ninety (90) days notice,  to remove Chalone
              as  distributor  of the Winery's wine in the State of  California,
              and to appoint one or more persons to act as  Chalone's  successor
              (which persons may include Paragon),  which person(s) shall assume
              those duties and responsibilities of Chalone as distributor of the
              Winery's  wine in the State of California as are delegated to them
              by the Managing  Joint Venture  Partner,  and shall be entitled to
              those  rights  and  benefits  of the  distributor  under the Joint
              Venture  Agreement as are  assigned to them by the Managing  Joint
              Venture  Partner;  and the right and power to appoint  one or more
              distributors  (which may include Paragon) of the Winery's wine for
              jurisdictions outside of the State of California, pursuant to such
              terms  and  conditions  as  the  Managing  Joint  Venture  Partner
              determines.  Any  disagreement  between  the members of the Review
              Committee  with respect to the  appointment  of a successor to the
              Managing  Joint Venture  Partner or with respect to the duties and
              responsibilities  of any such  successor  shall not be  subject to
              resolution by  arbitration  pursuant to the  provisions of Article
              XVIII of the Joint Venture Agreement."


         Section 8.5(b) is hereby amended in its entirety to read as follows:


                  "(b)  Subject to the  provisions  of this  subsection  8.5(b),
         Chalone may also be removed, for cause, by Paragon (assuming Paragon is
         then  a  Joint  Venture  Partner  and  is not  in  default  under  this
         Agreement).  A ground for removal for cause of Chalone by Paragon shall
         include, without limitation,  in the event that there has been a Change
         in Control of Chalone and the Acquiror  (Section  8.5(a)  hereof),  has
         provided the written notice called for by Section


                                      -15-



         8.5(a)(ii)  hereof,  the subsequent  failure by Chalone to use its best
         reasonable  efforts,  as Managing  Joint  Venture  Partner of the Joint
         Venture,  to  implement  fully  the terms  and  provisions  of the then
         applicable  business plan adopted by the Review  Committee.  If Paragon
         elects to remove  Chalone for cause,  it shall give  written  notice to
         Chalone of its  election to remove  Chalone as Managing  Joint  Venture
         Partner,  specifying  its reasons for the election.  Chalone shall have
         thirty (30) days  within  which to satisfy the  concerns  expressed  by
         Paragon.  If,  at the  end of  said  30-day  period,  Chalone  has  not
         satisfied   Paragon's   concerns  and  if  Chalone  disputes  Paragon's
         election,  then the Joint Venture Partners shall submit the question of
         whether  sufficient  grounds  exist to remove  Chalone,  for cause,  as
         Managing  Joint  Venture  Partner  of the  Joint  Venture,  to  dispute
         resolution  pursuant to the  provisions of Article XVIII hereof.  Until
         resolution  of the dispute  pursuant to Article  XVIII,  Chalone  shall
         continue  to serve as  Managing  Joint  Venture  Partner  of the  Joint
         Venture.  If, pursuant to the dispute resolution  mechanisms of Article
         XVIII,  Paragon's  election to remove Chalone as Managing Joint Venture
         Partner of the Joint Venture for cause is  confirmed,  then and in such
         event  Paragon  shall  have  the  right to  nominate  and  appoint  the
         successor  (which may be Paragon) to Chalone as Managing  Joint Venture
         Partner or as manager of the Joint  Venture  without being a Partner of
         the Joint Venture.  If Chalone does not agree with Paragon's nominee to
         serve as  Managing  Joint  Venture  Partner  or  manager  of the  Joint
         Venture,  then  either  party may  submit  the  dispute  to  resolution
         pursuant to the provisions of Article XVIII hereof, with the sole issue
         to be determined  whether or not  Paragon's  nominee is fit to serve as
         Managing Joint Venture Partner or manager of the Joint Venture.  Unless
         both parties agree otherwise, the aforesaid proceeding shall be brought
         as a separate  proceeding from any proceeding  brought to determine the
         validity of Paragon's election to remove Chalone for cause."


         Section  8.5(d)(iv)  is  hereby  amended  in its  entirety  to  read as
follows:


                  "(iv)  Supervising  the  general  manager of the Winery or, if
         there is no general manager of the Winery, the winemaker;"


8.       Clarification  of  Article  IX of  the  1991  Joint  Venture  Agreement
         (Transfer of Joint Venture Interests)


         The Joint Venture  Partners hereby confirm that the interest of a Joint
Venture  Partner  subject  to the  provisions  of  Article  IX of the 1991 Joint
Venture Agreement 



                                      -16-


includes the interest of the Joint Venture Partner as a member of Brand Name LLC
to the  extent,  and only to the  extent,  that the Joint  Venture  Partner is a
member of Brand Name LLC.  For  purposes  of Section  17.2 of the Joint  Venture
Agreement,  the interest of a Joint  Venture  Partner in the Joint Venture shall
include the interest of the Joint Venture  Partner as a member of Brand Name LLC
only from and after such time as  Chalone  becomes a member of Brand Name LLC by
the exercise of the option  granted to it pursuant to the  provisions of Section
3.7 of the Joint  Venture  Agreement.  Prior to  Chalone's  becoming a member of
Brand Name LLC,  the  interest  of neither  Joint  Venture  Partner of the Joint
Venture  shall,  for  purposes of Section 17.2 of the Joint  Venture  Agreement,
include the interest of the Joint Venture Partner as a member of Brand Name LLC.
From and after the date that Chalone  becomes a member of Brand Name LLC,  then,
for the purposes of Section 17.2 of the Joint Venture Agreement, the interest of
a Joint  Venture  Partner in the Joint  Venture  shall include the Joint Venture
Partner's  membership in Brand Name LLC and, for purposes of Section 17.2, there
shall  be  credited  to  the  "Capital  Account"  of a  Joint  Venture  Partner,
attributable to the Partner's membership interest in Brand Name LLC, Two Hundred
Thousand Dollars ($200,000).


9.       Amendment to Article X of the 1991 Joint  Venture  Agreement  (Right of
         Purchase Upon Change in Control)


         Article X of the 1991 Joint Venture  Agreement is hereby deleted in its
entirety. From and after the effective date of this Amendment, the provisions of
Article  X shall  have no  further  force or effect  and,  upon any  "Change  in
Control" of a Joint Venture Partner,  the other Joint Venture Partner shall have
no right or option to purchase the Joint Venture Partner's interest in the Joint
Venture. A Change in Control of Chalone,  however, may result in the position of
the Managing Joint Venture Partner  becoming vacant (Section 8.5(a) of the Joint
Venture Agreement),  and a Change in Control of Chalone shall trigger payment of
the  Escalated  Purchase  Price Credit  (Section  12.2(vii) of the Joint Venture
Agreement).


10.      Amendments  to  Article  XII  of  the  1991  Joint  Venture   Agreement
         (Escalated Purchase Price Credit for Paragon)


         Article XII of the 1991 Joint  Venture  Agreement is hereby  amended in
the following respects, and in the following respects only.


         "12.2    Events  Calling  for Payment or Credit of  Escalated  Purchase
                  Price Credit


                           The Escalated  Purchase Price Credit shall be paid to
              or credited for the benefit of Paragon upon the  occurrence of any
              of the following events:


                                      -17-


                           (i) A purchase  by Chalone of  Paragon's  interest in
                  the Joint  Venture  pursuant to the  provisions  of Article IX
                  hereof;


                           (ii) A purchase by Paragon of  Chalone's  interest in
                  the Joint  Venture  pursuant to the  provisions  of Article IX
                  hereof;


                           (iii)  A sale  of all or  any  portion  of the  Joint
                  Venture  as an entity or all or any  portion of its assets not
                  in the ordinary course of business;


                           (iv) A  sale  by  Paragon  of the  Brand  Name  under
                  circumstances  pursuant to which  Chalone is entitled to share
                  in the  proceeds  from the sale of the Brand Name  pursuant to
                  Section 6.2 hereof but,  in such event,  Chalone  shall pay to
                  Paragon the lesser of the Escalated  Purchase  Price Credit or
                  its share of the  proceeds  from sale of the Brand  Name (with
                  the balance of the Escalated  Purchase  Price  Credit,  if not
                  paid in full,  payable upon the occurrence of any of the other
                  events specified in this Section 12.2 or in this Agreement);


                           (v) A sale by  Chalone of its  interest  in the Joint
                  Venture pursuant to the provisions of Article IX hereof;


                           (vi) The  admission  to the Joint  Venture  of one or
                  more third-party Joint Venture Partners; or


                           (vii)    A Change in Control of Chalone.


                  If the event  calling for  payment or credit of the  Escalated
         Purchase  Price  Credit  represents  a sale of less than all of a Joint
         Venture  Partner's  interest in the Joint Venture  (clauses (i) or (ii)
         above) or a sale of less than the entire  business of the Joint Venture
         or less than all of its assets not in the  ordinary  course of business
         (clause (iii) above),  then an appropriate  pro ration of the Escalated
         Purchase Price Credit shall be made. In all events, a pro ration of the
         Escalated  Purchase Price Credit shall be made upon any event described
         in clause (vi) above equal to the  percentage  obtained by dividing (i)
         the percentage  interest in the Joint Venture obtained by the new Joint
         Venture  Partner or Partners  in the Joint  Venture by (ii) 50%. If the
         event  calling for payment or credit of the  Escalated  Purchase  Price
         Credit is a Change in Control of Chalone (clause (vii) above), then and
         in such  event  Chalone  shall pay to  Paragon  an amount  equal to the
         Escalated  Purchase  Price  Credit  within  thirty  (30) days after the
         effective date of the Change in Control of Chalone."

13.      Amendments  to  Article  XVIII  of the  1991  Joint  Venture  Agreement
         (Arbitration)


         Article XVIII of the 1991 Joint Venture  Agreement is hereby amended in
its entirety to read as follows:


                  "18.1 Scope; Dispute Resolution Forum


                           (a) The parties agree that all disputes arising under
                  this Agreement,  and all matters  specifically to be submitted
                  to arbitration  under this  Agreement,  shall be determined as
                  provided  for  in  this  Article  XVIII.  Notwithstanding  the
                  foregoing,  it is not the  intent  of the  parties  hereby  to
                  mediate or arbitrate disputes that may arise from time to time
                  among members of the Review  Committee,  such as matters to be
                  decided by the Review Committee  pursuant to the provisions of
                  Section  8.1(b)  hereof.  Any such dispute shall not be within
                  the scope of this Article XVIII.


                           (b) Should any dispute within the scope of subsection
                  (a) of this  Section  18.1  arise  between  the Joint  Venture
                  Partners   that  the  Partners  are   incapable  of  resolving
                  themselves through good faith  negotiation,  then such dispute
                  or  controversy  shall first be  submitted  for  mediation  by
                  J.A.M.S./ENDISPUTE  ("JAMS")  in  San  Francisco,  California,
                  pursuant to the mediation  services  provided by JAMS.  Should
                  the  dispute  between  the  Joint  Venture   Partners  not  be
                  successfully mediated by JAMS within 60 days of its submission
                  (subject to any extension  agreed to by the Partners) then and
                  in such  event the  dispute  shall be  submitted  for  binding
                  arbitration, not by JAMS (unless the Partners explicitly agree
                  to arbitration by JAMS),  but in accordance with the following
                  procedure:


                           (i)  Within  thirty  (30)  days of the date  that the
                  Partners  determine to resolve their  dispute by  arbitration,
                  each  Partner   shall  notify  the  other  of  an   arbitrator
                  designated by the Partner.  The two arbitrators shall promptly
                  meet and confer in an attempt to resolve the  dispute.  If the
                  two  arbitrators  so named are unable to resolve the  dispute,
                  they shall appoint a third arbitrator.  The decision of two of
                  the three arbitrators shall be conclusive and binding upon the



                                      -20-


                  parties and may be confirmed  as provided by Sections  1285 et
                  seq. of the Code of Civil  Procedure.  The  arbitrators  shall
                  consider such evidence and follow such  procedures as they may
                  deem relevant or appropriate to resolve the dispute  submitted
                  to them.


                  18.2     Costs; Submission to Jurisdiction


                           It  is  agreed  that  the  prevailing  party  in  any
                  arbitration  brought  pursuant to this Article  XVIII or other
                  action  arising  from or relating to this  Agreement  shall be
                  entitled  to   reimbursement   of  its  reasonable  costs  and
                  expenses,   including  attorneys'  fees.  Each  Joint  Venture
                  Partner   consents  to  the  exercise   over  it  of  personal
                  jurisdiction by the arbitrator(s)  selected by the Partners to
                  resolve any dispute hereunder."


14.      Due Execution and Validity of This Amendment


         (a) Chalone  represents and warrants to Paragon that this Amendment has
been duly  authorized  and  executed by it pursuant to all  necessary  corporate
action and, upon its due execution by Paragon,  this Amendment  shall be a valid
and binding agreement of Chalone,  enforceable against it in accordance with its
terms and conditions.


         (b)  Paragon  hereby  represents  and  warrants  to  Chalone  that this
Amendment has been duly  authorized and executed by it pursuant to all necessary
corporate  action and, upon its due  execution by Chalone,  shall be a valid and
binding  agreement of Paragon,  enforceable  against it in  accordance  with its
terms and conditions.


15.      Continued Validity of the 1991 Joint Venture Agreement


         Other than as expressly amended hereby, the terms and provisions of the
1991 Joint Venture Agreement shall remain in full force and effect, binding upon
Chalone and Paragon and their respective successors and assigns.
