      IT IS AGREED:

                                   ARTICLE I
                            THE ORIGIN STOCK PURCHASE

      SECTION  1.01  Purchase  and  Sale.  Upon the  terms  and  subject  to the

                                       2
<PAGE>

            (b) Payments.

                  (i) Initial  Payment.  At the Closing,  the sum of $10,000,000
(the "Initial Payment"), less the Holdback Amount, will be paid by wire transfer
of immediately  available United States dollars to Origin  Stockholders or their
designees  as  specified  in a written  notice  given to CCAC or Chardan Sub, no
later  than two  business  days  prior to the  Closing,  for the  purpose of the
acquisition of the Origin Stock.

                  (ii)  Additional  Payments.  In  the  event  that  any  of the
following  events  occur any year after the  Closing  Date and ending the fiscal
year  ending  December  31,  2008 (or June 30,  2009 if the  fiscal  year of the
combined entity is changed),  Chardan Sub shall promptly pay in aggregate to the
Origin  Stockholders or their  designees,  as an addition to the Purchase Price,
the  amounts set forth  below in cash by wire  transfer  to the  accounts of the
Origin  Stockholders  as specified on Schedule  1.02(a) in respect of the Origin
Stock ownership:

                        (a) If Chardan  Sub  receives  at least  $40,000,000  in
gross proceeds in additional financing  ("Financing  Adjustment") as a result of
(1) the  call of  CCAC's  presently  outstanding  public  warrants  (which  such
warrants  will be assumed by Chardan  Sub at the  Closing),  (2)  Chardan  Sub's
successful  completion of a secondary  offering,  or (3) the private  investment
into Chardan Sub by a strategic investor,  then the Origin Stockholders or their
designees shall be entitled to receive an additional $15,000,000; or

                        (b) If Origin  generates a net positive cash flow of not
less  than  $2,000,000  in any  fiscal  year  ending  December  31,  or June 30,
beginning  December  31, 2005 or June 30,  2006,  respectively  depending on the
fiscal year ("Earnings  Adjustment"),  the Origin Stockholders shall be entitled
to  receive  75% of the  net  positive  cash  flow  of  such  fiscal  year up to
$7,500,000  per year until a total of $15,000,000  has been  received;  provided
that the board of directors of the surviving corporation, solely on the basis of
a proposal by Dr.  Han,  as a director,  may reduce the amount to be paid in any
one year.

                  (iii) In the event  that  both an  Earnings  Adjustment  and a
Financing  Adjustment  occurs,  the  maximum  amount  to be paid  to the  Origin
Stockholders  shall be  $15,000,000.  For purposes of example  only, if Earnings
Adjustments  have  occurred  such that the Origin  Stockholders  are entitled to
receive  $5,000,000  (in one or more  installments)  and a

                                       3
<PAGE>

Financing Adjustment  subsequently occurs, only the balance of $10,000,000 shall
be paid to the Origin  Stockholders as a result of a Financing  Adjustment for a
total of $15,000,000.

                  (iv)  If any  amount  is to be  paid  on  either  a  Financing
Adjustment or Earnings  Adjustment,  then such amount will be paid to the Origin
Stockholders  pursuant  to  the  original  payment  instructions  received  from
Origin's Shareholders prior to the Closing as set forth on Schedule C.

            (c) Holdback. The sum of $250,000 ("Holdback Amount") to be withheld
from the  Initial  Payment,  representing  a portion of the cash  portion of the
Purchase  Price will be retained  by Chardan Sub for a period of 12 months.  The
Holdback  Amount will be security  for the  indemnification  obligations  of the
Origin  Stockholders set forth in Article X. Subject to this section and Article
X, on the 12  month  anniversary  of the  Closing,  or the  first  business  day
thereafter, Chardan Sub shall deliver the Holdback Amount pro rata to the Origin
Stockholders (or their designees) in the same proportions as the Initial Payment
was allocated among them.  Chardan Sub may withhold from the Holdback Amount the
equivalent  of any  amount  then in dispute  related to the Origin  Stockholders
indemnification  obligations  arising pursuant to Article X or for which Chardan
Sub has  notified  the Origin  Stockholders  of an  indemnification  Claim.  Any
withheld  Holdback  Amount,  to the extent not  applied  in  satisfaction  of an
indemnification Claim, will be paid by Chardan Sub promptly on resolution of the
dispute or Claim.  Nothing in this  section  shall be  construed as limiting the
liability of the Origin  Stockholders  for  indemnification  claims or any other
claim by Chardan,  Chardan Sub or any other rightful claimant,  and the Holdback
Amount  shall  not be  considered  liquidated  damages  for any  breach  of this
Agreement or any other matter related hereto.

      SECTION 1.03 Earn-Out Agreement.  So long as CCAC,  following the Closing,
on a consolidated  basis,  achieves or exceeds the after tax profits  (excluding
any after tax operating  profits from any acquisition by Origin that was for the
issuance of securities that has a dilutive effect on the holders of common stock
of CCAC,  or Chardan  Sub after the  Closing,  and before  the  expenses  of the
transaction  contemplated  by this  Agreement  and the  expenses of director and
employee options in each of the fiscal years)  calculated for the period of July
1 to the succeeding  June 30, ending on June 30 in each of 2006,  2007, 2008 and
2009 as set forth below, the Origin

                                       4
<PAGE>

Stockholders shall receive after the Closing the number of shares of Chardan Sub

it conducts requires  qualification  (which jurisdictions are listed in Schedule

aggregate,  would not have a material  adverse  effect on the Business,  assets,
operations, financial condition, liquidity or prospects of Origin and the Origin
Subsidiaries,  separately and as a whole  ("Origin  Material  Adverse  Effect").
Origin has all  requisite  power and  authority  to own,  lease and  operate its

its terms, except (i) as enforceability may be limited by applicable bankruptcy,
insolvency,  reorganization,  moratorium, fraudulent transfer or similar laws of
general application now or hereafter in effect affecting the rights and remedies
of  creditors  and by  general  principles  of  equity  (regardless  of  whether
enforcement  is  sought  in a  proceeding  at  law or in  equity)  and  (ii)  as

                                       8
<PAGE>

enforceability  of any  indemnification  provision may be limited by federal and
state securities laws and public policy of the United States, BVI and PRC.

            (b) Neither the execution  and delivery of this  Agreement or any of
the other  Transaction  Documents  contemplated  hereby by Origin or each Origin
Stockholder nor the  consummation  of the  transactions  contemplated  hereby or
thereby will (i) except as set forth in Schedule 3.03,  conflict with, result in
a breach or violation of or constitute  (or with notice of lapse of time or both
constitute) a default  under,  (A) the Memorandum and Articles of Association of
Origin or (B) any law,  statute,  regulation,  order,  judgment or decree or any

             REPRESENTATION AND WARRANTS OF THE ORIGIN SUBSIDIARIES

      Origin and the Origin Stockholders,  jointly and severally,  represent and
warrant to CCAC and Chardan Sub as of the Closing, as follows:

      SECTION 4.01 The Origin Subsidiary Stock.

            (a)  Ownership.   Origin,  either  directly  or  through  the  Stock
Consignment  Agreements  and/or the  Technology  Service  Agreement set forth in
Section  2.03 is the actual  controller  of the shares of the Origin  Subsidiary
Stock,  free and clear of all Lien  which,  except  for 2.04% of each of Beijing
Origin and Henan Company owned by other  parties,  shares  constitute all of the
outstanding  shares  of  capital  stock of the  Origin  Subsidiaries.  Except as
indicated  in the  preceding  sentence,  there are no  consignment,  operational
contracts  and/or  equity  transfer  arrangements,  options,  warrants  or other
contractual rights (oral or written), trusts or other arrangements of any nature
which give any Person  (other  than  Origin) the right to acquire or control any
capital  stock  of the  Origin  Subsidiaries,  whether  or not such  rights  are
presently exercisable.  Except as indicated in the preceding sentence, there are
no operational contracts and/or equity transfer arrangements,  options, warrants
or other contractual  rights (oral or written),  trusts or other arrangements of
any nature  which give any Person  (other  than  Origin) the right to any asset,
income,  dividend,  distribution,  property  interest  or direct  or  beneficial
interest in any, or from any, of the Origin Subsidiaries.

            (b)  Capitalization.  The  authorized  capital  stock of each Origin
Subsidiary  is set forth on Schedule A. Except for Beijing  Origin State Harvest

which the capital is committed,  all of the outstanding  shares of capital stock
of each Origin Subsidiary are validly issued, fully paid and non-assessable.

Subsidiary is a corporate  entity duly organized,  validly  existing and in good
standing  under the law of its  jurisdiction  of  incorporation  as set forth on
Schedule 4.02.  Each Origin  Subsidiary is duly qualified to do business in each
of the  jurisdictions  in which the property  owned,  leased or operated by such
Origin  Subsidiary  or the nature of the  business  which it  conducts  requires
qualification  (which  jurisdictions  are listed in Schedule 4.02), or if not so
qualified, such failure or failures, in the aggregate,  would not have an Origin
Material Adverse Effect. No Origin Subsidiary owns, directly or indirectly,  any
capital stock or any other  securities  of any issuer or any equity  interest in
any  other  entity  and is not a party  to any  agreement  to  acquire  any such
securities  or  interest,  except as set forth on  Schedule  4.02.  Each  Origin

properties and to carry on its business as now being  conducted and as presently

delivery and  performance of the  Transaction  Documents in connection  with the
Origin Stock Purchase has been duly and validly taken. The Transaction Documents
have been duly  executed and delivered by each Origin  Subsidiary  party to such
agreements and constitute the valid, binding, and enforceable obligation of each
of  them,   enforceable   in  accordance   with  their  terms,   except  (i)  as
enforceability   may  be   limited   by   applicable   bankruptcy,   insolvency,
reorganization,  moratorium,  fraudulent  transfer  or  similar  laws of general
application  now or  hereafter  in effect  affecting  the rights and remedies of
creditors and by general principles of equity (regardless of whether enforcement
is sought in a proceeding at law or in equity) and (ii) as enforceability of any
indemnification  provision  may be limited  by the law and public  policy of the
PRC.

            (b) Neither the execution nor delivery of the Transaction  Documents
or any of the other documents  contemplated thereby by any Origin Subsidiary nor
the consummation of the

                                       13
<PAGE>

transactions contemplated thereby will (i) except as set forth in Schedule 4.03,
conflict with,  result in a breach or violation of or constitute (or with notice
of lapse of time or both constitute) a default under, (A) the charter  documents
of any Origin Subsidiary or (B) any law, statute, regulation, order, judgment or
decree or any  instrument,  contract  or other  agreement  to which  any  Origin
Subsidiary  is a party or by  which  any of them  (or any of the  properties  or
assets of Origin) is subject or bound;  (ii) result in the  creation of, or give

modify, or give any third party the right to terminate or modify, the provisions
or terms of any  contract  to which any Origin  Subsidiary  is a party,  or (iv)
result in any suspension,  revocation,  impairment,  forfeiture or nonrenewal of
any permit, license, qualification,  authorization or approval applicable to any
Origin Subsidiary.

      SECTION 4.04  Consents and  Approvals.  Except as listed and  described on
Schedule 4.04, the execution and delivery of the  Transaction  Documents by each
Origin  Subsidiary do not, and the performance of the  Transaction  Documents by
each of them will not,  require any consent,  approval,  authorization  or other
action by, or filing with or notification to, any Governmental Authority, except
where failure to obtain such consents, approvals,  authorizations or actions, or
to make  such  filings  or  notifications,  would not  prevent  any of them from
performing any of their material obligations under the Transaction Documents and
would not cause an Origin Material Adverse Effect.

      SECTION  4.05  Financial  Statements.  Prior  to  the  execution  of  this
Agreement,  Origin  has  delivered  to CCAC  consolidated  balance  sheets as at
December 31, 2001, 2002 and 2003, and related consolidated  statements of income

Except  as set  forth on  Schedule  4.12,  each  Contract  to which  any  Origin
Subsidiary  is a  party  is a  valid  and  binding  obligation  of  such  Origin
Subsidiary  and, to the best of the knowledge of each Origin  Subsidiary and the
Origin  Stockholders,  enforceable  in accordance  with its terms (except as the
enforceability thereof may be limited by any applicable  bankruptcy,  insolvency
or other laws affecting  creditors' rights generally or by general principles of
equity,  regardless of whether such enforceability is considered in equity or at
law), and is in full force and effect  (except for any Contracts  which by their
terms  expire after the date hereof or are  terminated  after the date hereof in
accordance with the terms thereof, provided,  however, that no Origin Subsidiary
will  terminate  any Contract  after the date hereof  without the prior  written
consent of CCAC,  which consent shall not be unreasonably  withheld or delayed),
and no Origin  Subsidiary  has  breached any  material  provision  of, nor is in
default in any material respect under the terms of any of the Contracts.

previously  have been delivered to CCAC.  Each Origin  Subsidiary  possesses all
Permits necessary,  in all material respects,  to own and operate its portion of
the  Business.  All such  Permits  are in full force and effect and each  Origin
Subsidiary and the officers,  directors and employees of such Origin  Subsidiary
have complied and each Origin Subsidiary will comply, and each Origin Subsidiary
shall cause its respective  officers,  directors and employees to comply, in all
material  respects  with all  terms of such  Permits  and will  take any and all
actions  necessary  to ensure  that all such  Permits  remain in full  force and
effect and that the terms of such Permits are not  violated  through the Closing
Date. No Origin  Subsidiary  is in default in any material  respect under any of
such Permits and no event has occurred and no condition  exists which,  with the
giving of notice,  the  passage of time,  or both,  would  constitute  a default
thereunder.   Neither  the  execution  and  delivery  of  this  Agreement,   the
Transaction Documents or any of the other documents  contemplated hereby nor the
consummation of the transactions  contemplated  hereby or thereby nor compliance
by any Origin  Subsidiary  with any of the  provisions  hereof or  thereof  will
result in any suspension,  revocation,  impairment,  forfeiture or nonrenewal of
any Permit applicable to the Business.

Intellectual Property owned by any other Person (including any rights enjoyed by
any Origin  Subsidiary by reason of its relationship with one of its affiliates)
in connection with the Business.

            (f) Ownership.  As of the date hereof,  each Origin Subsidiary owns,
and at the Closing  Date,  will own all right,  title and interest in and to all
Intellectual  Property  rights used in connection  with the Business,  and those
Intellectual  Property  rights were developed and created solely by employees of
such Origin  Subsidiary  acting within the scope of their employment or by third
parties (all of which  employees and third parties have validly and  irrevocably
assigned all of their rights therein to such Origin  Subsidiary) and each Origin
Subsidiary is duly and validly licensed to use all other  Intellectual  Property

            (h) Infringement.  The Intellectual Property used in connection with
the Business by each Origin Subsidiary does not infringe or  misappropriate  any
Intellectual  Property rights of any Person under the laws of any  jurisdiction.
To the best of its  knowledge,  no  notice,  claim or  other  communication  (in
writing or  otherwise)  has been  received  from any Person:  (A)  asserting any
ownership interest in any material Intellectual Property used in connection with
the Business; (B) of any actual,  alleged,  possible or potential  infringement,
misappropriation or unauthorized use or disclosure of any Intellectual  Property
used in connection with the Business,  defamation of any Person, or violation of
any other right of any Person  (including  any right to privacy or publicity) by
any  Origin  Subsidiary  or  relating  to  the  Intellectual  Property  used  in
connection  with  the  Business;  or  (C)  suggesting  or  inviting  any  Origin
Subsidiary  to  take a  license  or  otherwise  obtain  the  right  to  use  any

Business  owned by,  exclusively  licensed to, held by or for the benefit of, or
otherwise controlled by such Origin Subsidiary.

            (i) Proceedings.  Except as set forth on Schedule 4.14(i), there are
no current or, to the best of its knowledge,  threatened  Proceedings (including
but not limited to any interference, reexamination,  cancellation, or opposition
proceedings)  arising out of a right or claimed  right of any person  before any
Governmental  Authority  anywhere  in the  world  related  to  any  Intellectual
Property used in connection with the Business owned by, exclusively licensed to,
held by or for the benefit of, or otherwise controlled by any Origin Subsidiary.

      SECTION 4.15 Title to and Condition of Assets.

            (a) Each Origin  Subsidiary has good and marketable title to all the
properties  and  assets  owned  by it.  Except  as set  forth  in the  September
Financial  Statements  and Schedule 4.15 together,  none of such  properties and
assets  is  subject  to  any  Lien,  option  to  purchase  or  lease,  easement,
restriction,  covenant,  condition or  imperfection of title or adverse claim of
any nature whatsoever, direct or indirect, whether accrued, absolute, contingent
or otherwise.

            (b) To the best of its  knowledge,  except as set forth in  Schedule
4.15, all buildings, structures,  improvements, fixtures, facilities, equipment,
all components of all  buildings,  structures  and other  improvements  included

limited  to  the  roofs  and  structural   elements  thereof  and  the  heating,
ventilation, air conditioning,  plumbing,  electrical,  mechanical, sewer, waste
water,  storm  water,  paving and  parking  equipment,  systems  and  facilities
included  therein  conform in all material  respects to all  applicable  Laws of
every Governmental  Authority having jurisdiction over any of the Real Property,
and every  instrumentality or agency thereof.  There are no unsatisfied requests
for any repairs,  restorations  or  improvements  to the Real  Property from any
Person,  including without  limitation any Governmental  Authority,  except such
requests of employees  as have been denied in the  exercise of prudent  business
and operational practices. There are no outstanding contracts made by any Origin
Subsidiary for any  improvements  to the Real Property which have not been fully
paid for. No person,  other than each Origin  Subsidiary,  owns any equipment or
other tangible  assets or properties  situated on the Real Property or necessary
to the operation of the Business,  except for leased items disclosed in Schedule
4.09 hereto.

            (c) To the best of its knowledge,  the use and operation of the Real
Property  is in  full  compliance  in  all  material  respects  with  all  Laws,
covenants,  conditions,  restrictions,  easements,  disposition  agreements  and
similar  matters  affecting the Real Property and,  effective as of the Closing,
each Origin  Subsidiary  shall have the right under all Laws to continue the use
and  operation of the Real  Property in the conduct of the  Business.  No Origin
Subsidiary has received any notice of any violation (or claimed violation) of or
investigation regarding any Laws.

            (d) To the best its knowledge, none of the buildings, structures and
other improvements  located on the Real Property,  the appurtenances  thereto or
the  equipment  therein or the  operation or  maintenance  thereof  violates any
restrictive  covenant  or  encroaches  on any  property  owned by  others or any
easement,  right  of  way or  other  encumbrance  or  restriction  affecting  or
burdening  such Real Property in any manner which would have an Origin  Material
Adverse Effect on the condition (financial or otherwise),  assets, operations or
results of  operations  of such  Origin  Subsidiary,  nor does any  building  or
structure of any third party  encroach upon the Real Property or any easement or
right of way benefiting the Real Property.  To the best its knowledge,  the Real
Property and its continued  use,  occupancy and operation as used,  occupied and
operated in the conduct of the Business does not constitute a nonconforming  use
under any Law.

            (e)  No  Origin  Subsidiary  has  received  written  notice  of,  or
otherwise had knowledge of, any condemnation,  fire, health,  safety,  building,
environmental, hazardous substances, pollution control, zoning or other land use
regulatory  proceedings,  either  instituted or planned to be instituted,  which
would have an effect on the  ownership,  use and operation of any portion of the
Real Property for its intended  purpose or the value of any material  portion of
the Real Property,  nor has any Origin Subsidiary received written notice of any
special assessment proceedings affecting any of the Real Property.

            (f) To the best of its knowledge,  all water,  sewer, gas, electric,
telephone  and  drainage  facilities,  and all other  utilities  required by any
applicable  law are installed to the property  lines of the Real  Property,  are
connected  pursuant to valid permits to municipal or public utility  services or
proper drainage facilities to permit full compliance with the requirement of all
Laws. To the best its knowledge,  no fact or condition exists which could result
in the  termination or reduction of the current access from the Real Property to
existing roads or to sewer or other utility services  presently serving the Real
Property.

            (g)  All  Permits,  certificates,   easements  and  rights  of  way,
including proof of dedication,  required from all  governmental  entities having
jurisdiction  over  the  Real  Property  for the use and  operation  of the Real
Property in the conduct of the Business and to ensure  vehicular and  pedestrian
ingress to and egress from the Real Property have been obtained.

            (h) No Origin  Subsidiary  has received  written  notice and has any
knowledge of any pending or  threatened  condemnation  proceeding  affecting the
Real  Property or any part  thereof or of any sale or other  disposition  of the
Real Property or any part thereof in lieu of condemnation.

            (i) No portion of the Real Property has suffered any material damage
by fire or other casualty which has not heretofore been completely  repaired and
restored to its original condition.

            (j)  There  are  no  encroachments  or  other  facts  or  conditions
affecting the Real Property that would be revealed by an accurate survey thereof
which would, individually or in the aggregate, interfere in any material respect
with the use,  occupancy or operation thereof as used,  occupied and operated in
the conduct of the Business.

concerning the Business,  including, without limitation,  financial information,
trade   secrets   and   "know-how,"   customers,   and   certain   methodologies
("Confidential Information").

                  (ii) The Origin  Subsidiaries will suffer  substantial  damage
which  will  be  difficult  to  compute  if  they  should  divulge  Confidential
Information   or  enter  a  business   competitive   with  that  of  the  Origin
Subsidiaries.

Confidential  Information  obtained or learned as a result of stock ownership of
Origin  or any  Origin  Subsidiary  and  employment  by  Origin  or  any  Origin
Subsidiary  except (i) with the express written consent of CCAC on or before the
Closing  Date and of Chardan  Sub's Board of Directors  thereafter;  (ii) to the
extent that any such  information is in the public domain other than as a result
of a  breach  of any  obligations  hereunder;  or  (iii)  where  required  to be
disclosed by court order,  subpoena or other government  process.  If any Origin
Stockholder  shall be required to make disclosure  pursuant to the provisions of
clause (iii) of the preceding sentence,  it will promptly,  but in no event more
than 72 hours after learning of such subpoena,  court order, or other government
process, notify, by personal delivery or by electronic means, confirmed by mail,

Origin or the relevant  Origin  Subsidiary to defend against the  enforcement of
such subpoena,  court order or other government process,  and (ii) permit Origin

relating to the enforcement thereof.

            (c) Records.  At the Closing,  each Origin Stockholder will promptly
deliver to Origin and each Origin  Subsidiary  all  original  memoranda,  notes,
records,  reports, manuals, formula and other documents relating to the Business

their control;  provided,  however, that they shall be entitled to retain copies
of such documents reasonably necessary to document their financial  relationship
with Origin and Origin Subsidiary.

            (d)  Non-Compete.  During  the  Non-Competition  Period,  no  Origin
Stockholder,  without the prior written permission of Origin, shall, anywhere in
the PRC, Hong Kong and Taiwan, directly or indirectly, (i) enter into the employ
of or render any  services to any  person,  firm or  corporation  engaged in any
business which is a "Competitive  Business" (as defined  below);  (ii) engage in
any Competitive  Business for his own account;  (iii) become  associated with or
interested in any Competitive Business as an individual,  partner,  shareholder,
creditor,  director, officer,  principal, agent, employee, trustee,  consultant,

or cause any other  person or entity to employ or  retain,  any  person  who was

Stockholder in the six-month period prior to the date that all  relationships of
such person  terminates  with  Origin,  any Origin  Subsidiary  or other  Origin
Stockholder;  or (v) solicit,  interfere  with,  or endeavor to entice away from

Competitive  Business,  any of its  customers or other persons with whom Origin,
any Origin  Subsidiary or any Origin  Stockholder  has a business  relationship.
However,  nothing in this Agreement  shall  preclude them from  investing  their
personal  assets in the securities of any  corporation or other business  entity
which is engaged in a Competitive  Business if such  securities  are traded on a
national stock exchange or in the over-the-counter market and if such investment
does not result in their  beneficially  owning, at any time, more than 1% of the
publicly-traded equity securities of such Competitive Business.

            (e)  Injunctive  Relief.  If any  Origin  Stockholder  breaches,  or
threatens to breach,  any of the  provisions  of Sections  6.04 (b), (c) or (d),
Origin and each  Origin  Subsidiary  shall have the right and remedy to have the
provisions  of this  Section  6.04  specifically  enforced  by

any  Governmental  Authority,  it being  acknowledged  and agreed by each Origin
Stockholder  that any such breach or  threatened  breach will cause  irreparable
injury to Origin and the Origin  Subsidiaries  and that money  damages  will not
provide an adequate remedy.

            (f)  Modification  of Scope.  If any provision of Sections 6.04 (b),
(c) or (d) is held to be unenforceable because of the scope, duration or area of
its applicability,  the Governmental  Authority making such determination  shall
have the power to modify such scope, duration, or area, or all of them, and such
provision or provisions shall then be applicable in such modified form.

known to them which may  entitle  CCAC (or  Chardan  Sub after the  Closing)  to
indemnification under this Section 10.01.

      SECTION 10.02  Indemnification  by CCAC.  Subject to the  limitations  set
forth in Section 10.04, CCAC (and Chardan Sub after the Closing) shall indemnify
and hold harmless each Origin Stockholder from and against,  and shall reimburse
each Origin  Stockholder  for, any Damages which may be  sustained,  suffered or
incurred by such Origin  Stockholder,  whether as a result of Third Party Claims
or  otherwise,  and which  arise or  result  from or in  connection  with or are
attributable  to the breach of any of CCAC's  representations  or  warranties or
covenants contained in this Agreement. The indemnity in the foregoing clause (a)
shall  survive the  Closing

                                       57
<PAGE>

for a period of four years  after the Closing  Date.  CCAC (or Chardan Sub after
the Closing)  shall give each Origin  Stockholder  prompt  written notice of any
Third  Party  Claims  or other  facts  and  circumstances  known to it which may
entitle them to indemnification under this Section 10.02.

      SECTION 10.03  Notice,  Etc. A Party  required to make an  indemnification
payment  pursuant  to  this  Agreement  ("Indemnifying  Party")  shall  have  no
liability  with respect to Third Party  Claims or otherwise  with respect to any
covenant,  representation,  warranty, agreement, undertaking or obligation under
this Agreement unless the Party entitled to receive such indemnification payment
("Indemnified  Party") gives notice to the Indemnifying Party specifying (i) the
covenant,  representation  or warranty,  agreement,  undertaking  or  obligation
contained herein which it asserts has been breached,  (ii) in reasonable detail,
the nature and dollar amount of any Claim the Indemnified Party may have against
the Indemnifying Party by reason thereof under this Agreement, and (iii) whether
or not the Claim is a Third Party Claim.  With respect to Third Party Claims, an
Indemnified  Party (i) shall give the  Indemnifying  Party prompt  notice of any
Third Party  Claim,  (ii) prior to taking any action with  respect to such Third
Party Claim, shall consult with the Indemnifying Party as to the procedure to be
followed in defending,  settling,  or compromising the Third Party Claim,  (iii)
shall not  consent to any  settlement  or  compromise  of the Third  Party Claim
without the written consent of the  Indemnifying  Party (which consent shall not
be  unreasonably  withheld or delayed),  and (iv) shall permit the  Indemnifying
Party,  if it so elects,  to assume the  exclusive  defense of such Third  Party
Claim  (including,  except  as  provided  in the  penultimate  sentence  of this
Section,  the compromise or settlement  thereof) at its own cost and expense. If
the Indemnifying  Party shall elect to assume the exclusive defense of any Third
Party Claim pursuant to this Agreement, it shall notify the Indemnified Party in
writing  of such  election,  and the  Indemnifying  Party  shall  not be  liable
hereunder for any fees or expenses of the Indemnified  Party's counsel  relating
to such Third Party Claim after the date of delivery to the Indemnified Party of
such notice of election.  The  Indemnifying  Party will not compromise or settle
any such Third Party Claim without the written consent of the Indemnified  Party
(which  consent  shall not be  unreasonably  withheld  or delayed) if the relief
provided is other than  monetary  damages or such  relief  would have a material
adverse effect on the Indemnified Party.  Notwithstanding the foregoing,  if the
Indemnifying  Party elects to assume the defense with respect to any Third Party
Claim, the  Indemnifying  Party shall have the right to compromise or settle for
solely  monetary  damages such Third Party Claim,  provided such settlement will
not  result  in or

                                       58
<PAGE>

have a material  adverse effect on the Indemnified  Party.  Notwithstanding  the
foregoing,  the Party which  defends any Third Party Claim shall,  to the extent
required by any  insurance  policies  of the  Indemnified  Party,  share or give
control thereof to any insurer with respect to such Claim.

      SECTION 10.04 Limitations.

            (a) No Origin  Stockholder or Origin  Stockholders shall be required
to indemnify  CCAC under  Section  10.01 unless the aggregate of all amounts for
which indemnity would  otherwise be due against them exceeds  $50,000,  but then
the Origin Stockholders will be liable for the full amount of Damages.

            (b) CCAC (or  Chardan  Sub after  Closing)  shall not be required to
indemnify any Origin Stockholder under Section 10.02 unless the aggregate of all
amounts for which indemnity  would otherwise be due against it exceeds  $50,000,
but then CCAC (or Chardan Sub after  Closing) will be liable for the full amount
of Damages.

            (c) If a Third Party Claim subject to  indemnification by any Origin
Stockholder is brought against Origin or any Origin Subsidiary and Origin and/or
the Origin Subsidiary  prevails in the defense thereof,  such Origin Stockholder
shall not be required to indemnify  such Origin  Subsidiary  or CCAC (or Chardan
Sub  after  Closing)  with  respect  to the  costs  of such  defense,  including
attorneys' fees.

      SECTION 10.05 Adjustment to Purchase Price; Setoff.

            (a) Purchase Price.  Any  indemnification  payments made pursuant to
Sections  10.01 and 10.02 shall be deemed to be an  adjustment  to the  Purchase
Price. To the extent that any Origin  Stockholder is obligated to indemnify CCAC
or the  Chardan  Sub after  Closing  under the  provisions  of the Article X for
Damages  reduced to a monetary  amount,  CCAC or Chardan Sub after Closing shall
have the right to adjust any  amount due and owing or to be due and owing  under
any agreement with the Origin  Stockholder,  whether under this Agreement or any
other  agreement  between  the Origin  Stockholder  and any of CCAC's or Chardan
Sub's affiliates,  subsidiaries or controlled persons or entities. To the extent
that  CCAC or  Chardan  Sub is  obligated  to  indemnify  Origin  or any  Origin
Stockholders  after Closing  under the  provisions of this Article X for Damages
reduced to a monetary amount,  Origin or any Origin  Stockholders  after Closing
shall

                                       59
<PAGE>

have the right to decrease any amount due and owing or to be due and owing under
any  agreement  with CCAC or Chardan Sub,  whether  under this  Agreement or any
other  agreement  between the Origin or Origin  Stockholder and any of CCAC's or
Chardan Sub's affiliates, subsidiaries or controlled persons or entities.

            (b)  Holdback  Amount.  Notwithstanding  the  foregoing,  CCAC,  and
Chardan Sub after the Closing, may apply all or a portion of the Holdback Amount
to satisfy any Claim for  indemnification  pursuant to this Article X. CCAC, and
Chardan  Sub after  the  Closing,  will hold the  Holdback  Amount  until  final
resolution  of the Claim or dispute.  The  Holdback  Amount is security  for the
indemnification  obligations of the Origin  Stockholders and is not a limitation
on the Damages  recoverable  or  liquidated  damages and such  security does not
limit any other right of set off or  recovery  under this  Agreement  or at law,
whether  pursuant  to  this  Agreement  or any  other  agreement  of the  Origin
Stockholders.

      SECTION  10.06  Claims  on  behalf  or in right of CCAC and  Chardan  Sub.
Pursuant to the  provisions of this Article X, if any Claim for  indemnification
is to be brought  against  the Origin  Stockholders  on behalf of or by right of
CCAC,  or Chardan Sub after the Closing,  such claims will be  determined by the
Independent  Committee of the Board of Directors.  Any settlement of a Claim for
indemnification  brought on behalf of or by right of CCAC,  or Chardan Sub after
the Closing,  shall be determined and approved by the  Independent  Committee of
the Board of Directors.  The Independent  Committee of the Board of Directors of
CCAC,  or Chardan Sub after the Closing,  will  consist of two persons,  none of
which are officers or employees  of CCAC,  or Chardan Sub after the Closing,  or
any of their operating  subsidiary  companies or are direct or beneficial owners
of 5% or more of the voting  capital  stock of CCAC,  or  Chardan  Sub after the
Closing.  For a period of not less than four  years  after the  Closing or until
final  resolution of Claims under this Section X brought by or by right of CCAC,
or Chardan Sub after the Closing, the board of directors of CCAC, or Chardan Sub
after the Closing,  will maintain a sufficient  number of directors such that it
will be able to maintain the Independent Committee.

this Agreement;

            (d) by Origin,  (i) if CCAC shall have breached any of its covenants
in Articles VII or VIII hereof in any respect or (ii) if the representations and

hereby;

            (g) by CCAC if the Board of Directors of CCAC shall have  determined
in good faith,  based upon the advice of outside legal counsel,  that failure to
terminate  this  Agreement  is  reasonably  likely  to  result  in the  Board of
Directors breaching its fiduciary duties to stockholders under applicable law by
reason of the  pendency of an  unsolicited,  bona fide  written  proposal  for a
superior transaction;

            (h) by either  CCAC or  Origin,  if, at CCAC's  Stockholder  Meeting

                          INVESTMENT ADVISORY AGREEMENT

      AGREEMENT made this 29th day of July, 1989, by and between MERRILL LYNCH
CAPITAL FUND, INC., a Maryland corporation (the "Fund"), and MERRILL LYNCH ASSET
MANAGEMENT, INC., a Delaware corporation (the "Advisor");

                              W I T N E S S E T H :

      WHEREAS the Fund is engaged in business as a diversified open-end
management investment company and is registered as such under the Investment
Company Act of 1940, as amended;

      WHEREAS the Advisor is engaged principally in rendering advisory services
and is registered as such under the Investment Advisers Act of 1940; and

      WHEREAS the Fund desires to retain the Advisor to render investment
supervisory and corporate administrative services to the Fund in the manner and
on the terms hereinafter set forth,

      NOW, THEREFORE, in consideration of the premises and the covenants
hereinafter contained, the Fund and the Advisor hereby agree as follows:

      1. The Fund hereby employs the Advisor to act as the investment advisor to
and manager of the Fund and to manage the investment and reinvestment of the
assets of the Fund and to administer its affairs, subject to the supervision of
the Board of Directors of the Fund, for the period and on the terms and
conditions set forth in this Agreement. The Advisor hereby accepts such
employment and agrees during such period, at its own expense, to render the
services and to assume the obligations herein set forth for the compensation
provided for herein.

<PAGE>

The Advisor shall for all purposes herein be deemed to be an independent
contractor and shall, unless otherwise expressly provided or authorized, have no
authority to act for or represent the Fund in any way or otherwise be deemed an
agent of the Fund.

      2. The Advisor shall regularly provide the Fund with investment research,
advice and supervision and shall continuously furnish the Fund with an
investment program for the assets of the Fund consistent with the principles set
forth in the Certificate of Incorporation, By-laws, Registration Statement and
Prospectus of the Fund and the requirements of the Investment Company Act of
1940, as amended.

      3. (a) The Advisor, at its own expense, shall furnish to the Fund office
space and all necessary office facilities, equipment and personnel for managing
the affairs and investments and keeping the books of the Fund. The Advisor
assumes and shall pay or reimburse the Fund for the compensation of all officers
and employees of the Fund and of all directors of the Fund who are interested
persons (as defined in the Investment Company Act of 1940, as amended) of the
Advisor. Except as otherwise expressly provided above, the Fund assumes and
shall pay all expenses of the Fund, including, without limitation: (1) the
charges and expenses of any custodian or depositary appointed by the Fund for
the safekeeping of its cash, securities and other property, (2) the charges and
expenses of auditors, (3) the charges and expenses of any transfer agents and
registrars appointed by the Fund, (4) the compensation of all directors who are
not interested persons of the Advisor, (5) brokers' commissions and issue and
transfer taxes chargeable to the Fund in connection with securities transactions
to which the Fund is a party, (6) interest charges, (7) all taxes and corporate
fees payable by the Fund to Federal, state or other governmental agencies, (8)
the cost of stock certificates representing shares of the Fund, (9) expenses in
connection with the repurchase and redemption of shares of the Fund, (10)

                                       2
<PAGE>

all expenses of shareholders' and directors' meetings and of preparing and
printing reports to shareholders and (11) charges and expenses of legal counsel
for the Fund.

      (b) The services of the Advisor to the Fund hereunder are not to be deemed
exclusive, and the Advisor shall be free to render similar services to others so
long as its services hereunder are not impaired thereby.

      4. (a) As full compensation for the services and facilities provided by
the Advisor hereunder, the Fund shall pay to the advisor at the end of each
calendar month a fee based upon the average daily value of the net assets of the
Fund, computed as of the time of close of trading on the New York Stock Exchange
on each day on which such Exchange is open for trading during such month, as
determined and computed in accordance with the answer to Item 30(a) to the form
N-8B-1 of the Fund on file with the Securities and Exchange Commission at the
following annual rates: 0.50% of that portion of the average daily net assets
not exceeding $250,000,000; 0.45% of that portion of the average daily net
assets exceeding $250,000,000 but not exceeding $300,000,000; 0.425% of that
portion of the average daily net assets exceeding $300,000,000 but not exceeding
$400,000,000; and 0.40% of that portion of the average daily net assets
exceeding $400,000,000. During any period when the determination of asset value
is suspended by the Board of Directors of the Fund, the asset value of a share
as of the last business day prior to such suspension shall for this purpose be
deemed to be the asset value at the close of each succeeding business day until
it is again determined.

      (b) In the event the total ordinary operating expenses of the Fund in any
fiscal year, inclusive of the fee paid to the Advisor pursuant to the preceding
paragraph but excluding taxes and governmental fees, interest paid and brokerage
commissions paid and expenses of

                                       3
<PAGE>

extraordinary items such as litigation, shall exceed an amount equal to 1-1/2%
of the first $30,000,000 of net assets of the Fund and 1% of the average
month-end total net assets of the Fund, based upon computations of net asset
value of the Fund made monthly, the Advisor shall pay on behalf of the Fund, or
reimburse the Fund for, any amount by which such total expenses exceed such
amount. Whenever the expenses of the Fund exceed a pro rata portion of the
annual expense limitation herein provided for, the estimated amount of
reimbursement under such expense limitation shall be applied as an offset
against the monthly payment of the investment advisory fee due to the Advisor.

      5. The Advisor shall not be liable for any error of judgment or mistake of
law or for any loss suffered by the Fund in connection with any investment
policy or the purchase, sale or redemption of any securities on the
recommendation of the Advisor. Nothing herein contained shall be construed to
protect the Advisor against any liability to the Fund or its security holders to
which the Advisor shall otherwise be subject by reason of willful misfeasance,
bad faith, gross negligence in the performance of its duties on behalf of the
Fund, reckless disregard of the Advisor's obligations and duties under this
Agreement or the violation of any applicable law.

      6. Unless sooner terminated as provided in Section 7, this Agreement shall
continue in effect from the date hereof until June 15, 1978, and from year to
year thereafter if such continuance is specifically approved at least annually
by the Board of Directors of the Fund or by vote of a majority of the
outstanding voting securities of the Fund and, provided that in either event
such continuance is also approved by the vote, cast in person at a meeting
called for the purpose of voting on such approval, of a majority of the
directors of the Fund who are not

                                       4
<PAGE>

parties to this Agreement or "interested persons" (as defined in the Investment
Company Act of 1940, as amended) of any such party.

      7. (a) This Agreement may be terminated at any time without payment of any
penalty by the Fund (i) on sixty days written notice to the Advisor, (ii) by
vote of the Board of Directors of the Fund or (iii) by vote of a majority of the
outstanding voting securities of the Fund, or by the Advisor on sixty days
written notice to the Fund.

      (b) This Agreement will automatically terminate in the event of its
assignment (as defined in the Investment Company Act of 1940, as amended).

      8. This Agreement may be amended at any time by mutual consent of the
parties, provided that such consent on the part of the Fund shall have been
approved by vote of a majority of the outstanding voting securities of the Fund.

                                       5
