     THIS JOINT VENTURE  AGREEMENT ("JV  Agreement") is made and entered into as
of this 10th day of November,  2005 (the "Effective Date"), by and among BLONDER
TONGUE  LABORATORIES,  INC., a Delaware  corporation ("BT"),  BLONDER TONGUE FAR
EAST, LLC, a Delaware limited liability company to be formed ("BTFE") and MASTER
GAIN INTERNATIONAL INDUSTRIAL, LIMITED, a Hong Kong corporation ("Master Gain").

                                   BACKGROUND

     The purpose of this Joint  Venture  Agreement  is to provide the  principal
terms and  conditions  under  which BT and  Master  Gain will  engage in a joint
venture  ("Venture")  and to  define  the  relative  rights  of the  parties  in
connection  therewith.  All  references  herein to  monetary  amounts and values
shall, unless otherwise specifically stated, be references to lawful currency of
the United States of America (US$).

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

     1.   Formation of Entities.

     (a) Off Shore  Entity.  Subject  to the terms and  conditions  hereof,  the
parties hereto shall,  promptly,  organize a new limited  liability entity under
the laws of Mauritius or some other jurisdiction  ("Offshore  Newco"),  with the
actual  jurisdiction  of formation  to be selected by BT following  consultation
with its legal and tax advisors.  The parties shall mutually agree upon the type
of limited  liability  entity to be formed and the legal name thereof in English
shall be such as the parties  hereto  mutually  agree upon,  as reflected in the
organizational  documents  thereof.  Upon formation,  the parties agree to cause
Offshore Newco to become a party to this JV Agreement.  All costs related to the
formation of Offshore Newco shall be paid equally be BT and Master Gain.

     (b) China  Entity.  Subject to the terms and  conditions  hereof,  promptly
following  the latest to occur of (i) the  formation  of  Offshore  Newco,  (ii)
approval  of  this  JV  Agreement  by any  governmental  authority  with  proper
jurisdiction,  if any, and (iii) approval of the formation,  capital  structure,
and governance  structure of China Newco (as defined below) by any  governmental
authority  with proper  jurisdiction,  the parties  hereto shall cause  Offshore
Newco to,  directly  or  through an  Intermediate  Entity  (as  defined  below),
organize a new limited  liability  entity under the laws of the Peoples Republic
of China ("PRC") ("China Newco").  The type of limited liability entity shall be
as required  under the laws and  regulations  of the PRC and any other  relevant
local or  provincial  laws or  regulations  governing the  providence  where the
Manufacturing  Facility (as defined below) shall be located  (collectively,  the
"PRC Laws") and the legal name  thereof in English  shall be such as the parties
shall mutually agree upon, provided, however, that the final form of entity must
be approved by each of BTFE and Master Gain.  It is the intention of the parties
hereto,  that  China  Newco be  formed  as a wholly  foreign  owned  enterprise,
commonly referred to in the PRC as a "WFOE".  All costs related to the formation
of China Newco shall be paid by Offshore Newco. To the fullest extent allowed by
PRC Law,  the  provisions  of this JV  Agreement  which  relate  to any right or
obligation  of any entity  within the Newco  Group (as defined  below)  shall be
incorporated  into the  operational  documents  governing the  organization  and
governance of such entity, the terms of which shall be mutually agreed to by the
parties.

     (c) Additional Entities.  To the extent required by the business activities
of Offshore  Newco or Chine  Newco,  BTFE and Master  Gain shall cause  Offshore
Newco or China Newco to,  directly or through an Intermediate  Entity,  organize
such  additional  limited  liability  entities under the laws of the PRC or such
other jurisdiction (including Hong Kong) as shall be deemed necessary,  with the
final form of each such  entity and its  jurisdiction  to be approved by each of
BTFE and Master Gain (each including any Intermediate  Entities,  an "Additional
Entity," and  together  with China Newco,  Offshore  Newco and all  Intermediate
Entities, the "Newco Group").

     (d) Tax Status.  Initially,  it is contemplated that Offshore Newco,  China
Newco (to the extent permitted under applicable law) and any Additional Entities
shall be organized as  "flow-through"  entities (i.e.,  partnerships) for United
States federal income tax purposes.

     2. Purpose and Benefits.

     (a) The  purposes  for which China Newco shall be formed  include,  without
limitation,  the following,  and the parties agree to cause China Newco to enter
into such  agreements or otherwise  take such actions as necessary to cause each
such purpose to be accomplished:

          all as shall be more  fully  set  forth  in the  operational  document
     governing the  organization  and  governance  of China Newco,  the terms of
     which shall be mutually agreed to by the parties:

          (i) to locate and acquire or build a manufacturing facility in the PRC
     capable of manufacturing  high quality  television  system  electronics and
     other electronics products (the "Manufacturing Facility");

          (ii) to provide contract manufacturing services to BT for such of BT's
     products as BT shall, in its sole  discretion,  determine from time to time
     ("Specified BT Products");

          (iii) to provide contract manufacturing services to third parties;

          (iv) to  actively  seek  out and  acquire  emerging  technologies  and
     licenses for emerging technologies ("Acquired Technology");

          (v)  to be  appointed  by BT  as  its  exclusive  distributor  of  the
     Specified BT Products ("Newco  Distributorship")  for the Asian,  Southeast
     Asian,   African,   European,   Middle  Eastern  and   Australian   markets
     (collectively, the "Newco Markets");

          (vi) to  market  and sell  the  Specified  BT  Products  in the  Newco
     Markets;

          (vii) to manufacture,  market and distribute  products  developed from
     the Acquired Technology ("Newco Products"); and

          (viii) to appoint BT as its exclusive  distributor  of Newco  Products
     ("BT Distributorship") for the North American, South American and Caribbean
     markets (collectively, the "BT Markets") and in such capacity, permit BT to
     market and distribute Newco Products in the BT Markets.

Notwithstanding the foregoing, the parties acknowledge that if upon consultation
with legal, tax, and accounting  advisors,  it is determined that some or all of
the purposes  outlined above would more  appropriately be delegated or allocated
to Offshore  Newco or an Additional  Entity,  then such shall be the case and in
that event appropriate additional definitive agreements shall be entered into by
the parties and actions taken, to implement the same.

     (b) The benefits  which the Venture  shall obtain  through the operation of
China Newco in the PRC are:

          (i) Tax free status for two years and extendable for an additional two
     years,  which  tax free  periods  shall  not  start  until  China  Newco is
     profitable;

          (ii) After tax free period,  for a period of three  years,  payment of
     taxes at half  (1/2)  the tax rate  required  for  Chinese  owned  entities
     (subject to any changes in the PRC tax laws);

          (iii)  Preferential  treatment and financial  incentives in connection
     with  access  to land  and/or  Manufacturing  Facilities  from the  Chinese
     government; and

          (iv)  Receipt of Chinese  government  rebates or waivers of up to 17%,
     but not  less  than  13%,  of the  import  VAT in  connection  with all raw
     materials/components manufactured in the PRC and incorporated into products
     exported from the PRC.

     3. Ownership Structure and Initial Equity.

     (a) Offshore Newco shall have the following equity structure:

                                 Equity Ownership         Economic Interest
     BTFE                              50%                       50%
     Master Gain                       50%                       50%

     Except as  provided  in  Section 15 hereof,  neither  BTFE nor Master  Gain
shall,  without the prior  written  consent of the other  party,  assign,  sell,
transfer,  pledge,  mortgage  or  otherwise  dispose  of all or any  part of its
Ownership interest in Offshore Newco to any third party.

     (b) China Newco shall be formed as a wholly  owned  subsidiary  of Offshore
Newco;  provided,  however,  that  to  the  extent  it is  determined  by BT (in
consultation  with its legal and accounting  advisors) that  interposing  one or
more entities  from  alternative  foreign  jurisdictions  (including  the United
States of America) (each, an  "Intermediate  Entity") between Offshore Newco and
China  Newco  would  be  beneficial  from a  corporate,  tax or  other  business
standpoint,  China Newco  shall be formed as a  wholly-owned  subsidiary  of the
Intermediate Entity,  provided further,  that the use of the Intermediate Entity
does not adversely affect Master Gain.

     4. Capital Contributions.

     (a) Initial Cash Capital  Contribution to Offshore  Newco.  BTFE and Master
Gain shall each make an initial cash capital  contribution  to Offshore Newco in
the amount of  US$25,000,  for an  aggregate  initial  capital  contribution  of
US$50,000 (the "Initial  Capitalization").  Such initial  capital  contributions
shall be made  within ten (10)  business  days after the  formation  of Offshore
Newco.

     (b)  Master  Gain  Contribution.  Within ten (10)  business  days after the
formation of Offshore  Newco,  Master Gain shall invest in Offshore Newco, as an
additional cash capital  contribution,  the aggregate sum of  US$5,850,000  (the
"Master Gain Investment"). Application to transfer the Master Gain Investment to
Offshore  Newco  within  two  business  days  is  acceptable,  if  the  transfer
transaction is  irreversible  and  subsequently  the actual transfer to Offshore
Newco takes  place  within 5 days of  approval  under PRC Laws,  but in no event
later than 60 days from the date of  applications.  The  repayment of the Master
Gain  Investment by Offshore  Newco to Master Gain shall be determined by mutual
agreement of the parties and in accordance with all applicable laws.

     (c) Additional  Capital.  As and to the extent that Offshore Newco requires
additional cash capital in excess of the Initial  Capitalization and Master Gain
Investment,  as  determined  by the mutual  agreement of the parties,  such cash
capital  shall be  provided  jointly and equally by Master Gain and BTFE up to a
combined total value of  US$1,000,000  (i.e.,  US$500,000  each).  If additional
capital is  required  in excess of this  amount,  Master  Gain and BT shall work
together to develop a plan to secure such additional funds,  including,  without
limitation, loans from Master Gain to Offshore Newco which would accrue interest
at the lowest applicable federal rate permitted under the United States Internal
Revenue  Code of 1986,  as  amended  (the  "Code")  to avoid the  imputation  of
interest,  with such interest to be paid only out of Offshore  Newco's  earnings
and profits. Any such loan from Master Gain would be interest only for the first
year and  thereafter  would  amortize over the term of sixty months,  subject to
being subordinated to indebtedness  provided by any third party or institutional
lenders as  contemplated  by Section 4(e) below.  In no event will any such loan
affect  the equity  ownership  or  economic  interest  percentages  set forth in
Section 3(a) above.

     (d) Offshore  Newco  Contribution.  The parties hereto shall mutually agree
upon  the  total  investment,   including,   without  limitation,  cash  capital
contributions  (the "Cash  Contribution") and potential loans ("Loans," together
with the Cash Contribution, the "Registered Capital") necessary to implement the
purposes of this Venture and obtain from the national  government of the PRC and
any local or provincial government the maximum financial incentives,  grants and
other  government-sponsored  opportunities  that are  available,  and shall seek
approval of such  Registered  Capital as required by PRC Law.  Upon  approval of
such Registered  Capital,  the parties shall cause Offshore  Newco,  directly or
through  an   Additional   Entity,   to  contribute  to  China  Newco  the  Cash
Contribution.  As  and to the  extent  required,  as  determined  by the  mutual
agreement of parties, Offshore Newco will lend all or a portion of the remainder
of the Master Gain  Investment to China Newco,  provided,  however,  such amount
shall not exceed the approved  Loan amount.  The  repayment of Offshore  Newco's
capital  contribution by China Newco and the  distribution  of dividends  and/or
earnings and profits from China Newco to Offshore  Newco and from Offshore Newco
to BTFE and Master Gain, shall be determined by mutual agreement of the parties,
subject to applicable law.

     (e) Third Party Capital.  To the extent that Offshore Newco, China Newco or
an Additional  Entity seeks or obtains  additional  capital in the form of loans
from third  parties  (including  financial  institutions),  none of BT,  BTFE or
Master Gain shall be required to provide such lender credit  enhancements in the
form of guaranties or otherwise.

     5.  Sale of CMTS  Technology.  Contemporaneously  with  the  formation  and
Initial  Capitalization  of Offshore Newco,  Master Gain shall sell,  assign and
transfer to  Offshore  Newco for  consideration  equal to Master  Gain's  actual
purchase price paid therefor,  as confirmed by providing Offshore Newco and BTFE
with such backup and support documentation as is reasonably requested (and which
is  estimated  by  Master  Gain to be  $650,000),  all of its  right,  title and
interest in and to the cable modem  termination  system  ("CMTS")  hardware  and
software  technology,  know-how  and other  assets  acquired by Master Gain from
Coresma Ltd. and its successors (collectively, the "CMTS Assets").

     6. BT Stock.

     (a) Advancement of Shares.  In consideration of the Master Gain Investment,
and  upon  payment  of  the  Master  Gain  Investment  to  Offshore  Newco,  and
consummation  of the sale of the CMTS  Assets  to  Offshore  Newco,  BTFE  shall
promptly invest in and advance to Offshore Newco One Million  (1,000,000) shares
of  unregistered BT common stock ("BT Stock") causing the same to be recorded in
the name of Offshore Newco on BT's stock registry;  provided, however, that such
shares  shall be subject to  cancellation  as  contemplated  by Section 6(e) and
Sections 15 and 20 of this JV Agreement.  To the extent that additional benefits
sought to be obtained  from the PRC for China Newco can be obtained  through the
transfer of some or all of the BT Stock as a loan to China Newco or as a capital
investment  in  China  Newco,  then  such  number  of  shares  of BT Stock as is
necessary  to obtain such  benefit  shall be lent to or invested in, as the case
may be, China Newco;  provided,  however, that such investment or loan does not,
together with all other  capital  contributions  and loans,  exceed the approved
Registered  Capital amount,  and further provided,  that such investment or loan
does  not  (after  consulting  with  BT's  legal  and  tax  advisors)  have  any
significant  adverse  U.S.  federal  income  tax  consequences  to  BT.  If  the
investment  and  advance  of BT  Stock to China  Newco is  determined  to have a
significant  adverse  U.S.  federal  income tax  consequence  to BT, the parties
hereto agree to cooperate in restructuring the proposed  transaction to minimize
or eliminate  such adverse  consequence  in such a manner as  preserves,  to the
fullest extent possible,  the economic  benefits intended to be afforded to each
of the parties.  The parties hereby represent and warrant that any investment or
advance of BT Stock to Offshore  Newco or China  Newco  shall be for  investment
purposes only and not with a view to distribution or resale thereof.

     (b) Voting  Trust.  The BT Stock  shall at all times be subject to a voting
trust  agreement  to be entered  into by Offshore  Newco (and China Newco if any
shares of BT Stock are lent or invested in China Newco),  pursuant to which each
of James A. Luksch and Robert J. Palle,  Jr., or such other person designated by
the Board of Directors  of BT,  would be appointed as a voting  trustee with the
right to vote the BT Stock for all  purposes.  The parties  will cause  Offshore
Newco and China Newco to execute  such voting  trust  agreements  and issue such
voting  trust  certificates  and  other  documents  and  instruments  as  deemed
reasonably  necessary by counsel for BT to implement the foregoing voting trust.
The voting trust shall be for the maximum term  permitted  under  applicable law
with such renewals as may be permitted under applicable law.

     (c) United States Securities Laws.  Offshore Newco (and China Newco, as the
case may be) shall,  at all times,  comply with all rules and regulations of the
Unites States Securities and Exchange Commission  applicable to its ownership of
any or all of such BT Stock,  including the timely filing of such notifications,
documents,  statements  and reports as are required by applicable  law, and with
respect  thereto,  as to  which  Robert  J.  Palle,  Jr.,  or his  designee,  is
authorized  to execute and file on behalf of Offshore  Newco or China Newco,  as
the case may be.

     (d)  Valuation.  The BT Stock  shall be valued  as of the date of  original
issuance  by BT to  Offshore  Newco (or  China  Newco,  if issued  the same day)
("Valuation Date"), which value shall be the average high and low selling prices
reported by the  American  Stock  Exchange  on such  issuance  date  ("Valuation
Amount").

     (e) Cancellation of BT Stock.

          (i) As and to the extent that the Newco Group  incurs a loss in fiscal
     year 2006 or any subsequent  fiscal year, that is reflected in or otherwise
     adversely  impacts the income  statement  of BT by virtue of BT's direct or
     indirect  ownership interest therein (whether under the equity method or as
     part of a consolidated  group with BT), BT shall be entitled to cancel such
     number  of  shares  of  the  BT  Stock,  valued  at  the  Valuation  Amount
     (determined  as of the  Valuation  Date),  as equals the amount of the loss
     recognized or to be recognized by BT on its income  statement.  The parties
     hereby  appoint  Robert J.  Palle as  attorney-in-fact  with full power and
     authority on behalf of Offshore  Newco and/or China Newco,  as the case may
     be, to endorse any  instruments  and execute any such  documents  as may be
     necessary to effectuate the foregoing. In addition, BT is hereby authorized
     to effect any cancellation  contemplated hereby and so notify BT's transfer
     agent thereof.

          (ii) As and to the extent that the Master Gain Investment is repaid to
     Master  Gain,  shares of BT Stock  having an  equivalent  Valuation  Amount
     (determined as of the Valuation  Date) to each such repayment of the Master
     Gain Investment, shall be cancelled by BT.

          (iii) Each certificate  representing any shares of BT Stock shall bear
     usual and  customary  restrictive  legends for shares of stock that are not
     subject to an effective  registration  statement under the U.S.  Securities
     Exchange Act of 1934, as amended, and a restrictive legend that such shares
     are subject to cancellation in accordance with Section 6(e) and Sections 15
     and 20 hereof.

     (f)  Restriction on Transfer.  Offshore Newco (or China Newco,  as the case
may be) shall not pledge,  hypothecate or otherwise encumber any of the BT Stock
without the express prior written  consent of BT, nor shall  Offshore  Newco (or
China  Newco,  as the  case may  be),  directly  or  indirectly,  absolutely  or
conditionally,  voluntarily or involuntarily, dispose of or part with all or any
portion of any BT Stock  including,  but not  limited  to, by sale,  assignment,
waiver,  gift, court order,  operation of law, equitable or other  distribution,
settlement,  exchange,  abandonment  or  disposal  ("Transfer"),  other  than  a
Transfer to BT and each  certificate  representing  any shares of BT Stock shall
bear a restrictive  legend to that effect. Any Transfer of BT Stock in violation
of this Section 6(f) shall be null and void, and BT shall be under no obligation
to  recognize  a  transferee  who  acquires  BT Stock  pursuant to a Transfer in
violation of this Section 6(f).

     (g) Tag Along/Drag Along Rights. If a bona fide offer from a third party to
purchase   Blonder  Tongue  common  stock   constituting  a  Change  in  Control
Transaction,  as defined  in  section  10(b)  herein,  (a "Bona Fide  Offer") is
received  by BT,  which BT desires  to accept,  Master  Gain  promptly  shall be
notified (the "Purchase  Notice") of the Bona Fide Offer,  specifying the terms,
including  price,  and the conditions of the Bona Fide Offer.  BT shall have the
option for a period of ninety (90) days from the date of the Purchase Notice, to
require  Newco Group to accept the Bona Fide Offer on the same terms,  including
price,  and subject to the same  conditions as specified in the Bona Fide Offer.
Furthermore,  in the  discretion  of  Master  Gain,  Newco  Group  may  elect to
participate  in such sale with  respect to all (but not less than all) shares of
BT Stock held by Newco Group,  by giving notice to BT within ten (10) days after
the  receipt of the  Purchase  Notice.  Upon  receipt of such notice from Master
Gain, BT will be required to include all of the BT Stock (as reduced pursuant to
the  provisions of Section 6(e), 15 and 20 hereof) held by Newco Group as of the
date of the  closing of such  transaction  within the total  shares of BT common
stock being sold  pursuant  to the Bona Fide Offer.  In the event of a Change in
Control  Transaction as  contemplated by this Section 6(g), in addition to those
rights set forth in this Section  6(g),  each of the parties shall also have the
additional right and obligations  granted to such party in Section 15(d) of this
JV Agreement.

     7. BT Intellectual Property.

     (a) BT shall,  at all times,  retain  ownership of all of its  intellectual
property  (whether  registered or unregistered,  registrable or unregistrable in
nature),  including,  without  limitation,  all  patents,  patent  applications,
trademarks,   trademark   applications,   copyrights,   copyright  applications,

ownership of, and all rights related to, all such BT Intellectual  Property,  as
it deems necessary, under the laws of the PRC or any other foreign jurisdiction.
Each of Master Gain,  Offshore Newco and China Newco and each Additional Entity,
if any, shall execute  agreements  pursuant to which each shall agree not to (i)
use any BT  Intellectual  Property for any purpose  without  BT's prior  written
consent as reflected in a license agreement with such party, (ii) challenge,  or
assist any other person to challenge,  the  proprietorship of BT or the validity
of any BT Intellectual  Property,  (iii) apply for registration of any of the BT
Intellectual Property in any part of the world (if capable of registration), but

rights in any BT  Intellectual  Property,  or (iv) divulge or disclose or permit
the disclosure of the BT Intellectual Property to third parties.

     (b) BT shall grant to Offshore  Newco a license for the term of the Venture
(with  revocability  triggered  by failure  to  maintain  specified  performance
standards and as provided elsewhere in this JV Agreement),  which license may be
sublicensed by Offshore Newco to China Newco, to use such of the BT Intellectual
Property as BT, in its sole and absolute discretion,  determines is necessary to
manufacture the Specified BT Products ("BT Licensed  Technology") for (i) resale
by China  Newco  within the Newco  Markets and (ii) BT, for sale in all parts of
the world other than the Newco Markets.

     (c) BT shall  enter into a services  agreement  with China Newco to provide
(i) engineering  development support to convert, if necessary,  the Specified BT

required  for sale of the  Specified  BT Products in the Newco  Markets and (ii)
engineering  and  manufacturing  support  necessary  to  assist  China  Newco in
manufacturing  the  Specified BT Products  with  equivalent  performance  to the

services set forth in this Section 7(c), including, without limitation, salaries
of  personnel  while  providing  this  support,  and  travel  and  living  costs
associated with this support.

     (b) BT  shall  be the  sole  and  exclusive  owner  of all  inventions  and

accordance  with their  respective  Economic  Interests  as set forth in Section
3(a).

     (b) Distributions from Capital  Transactions.  Except as otherwise provided
herein,  any distributions from Offshore Newco (including,  without  limitation,
cash  flow  attributable  to  any  entity  within  the  Newco  Group)  that  are
attributable  to a capital  transaction  of Offshore Newco (or any entity within
the Newco  Group) or that are  attributable  to a Change in Control  Transaction
shall be distributed to BTFE and Master Gain in accordance with the following:

          (i) First, to the extent any portion of the value realized as a result
     of  such  capital   transaction   or  Change  in  Control   Transaction  is
     attributable  to the BT Stock,  such amount shall be  distributed to Master
     Gain.

          (ii) Second,  any remaining amounts  distributable as a result of such
     capital  transaction or Change in Control  Transaction shall be distributed
     to BTFE and  Master  Gain in  accordance  with  their  respective  Economic
     Interests as set forth in Section 3(a).

     For purposes of the foregoing,  (i) the term "capital  transaction"  means,
with respect to an entity, a sale or transfer of substantially all of the assets
of such entity, a merger of such entity with or into any other entity,  the sale
of substantially  all of the interests of such entity,  or any other transaction

term "Change in Control Transaction" means the (i) consolidation,  merger, share
exchange  or  other  business  combination  involving  BT in  which  immediately
following such transaction either (x) less than 50% of the directors or managers
of  the  surviving  parent  entity  immediately  following  the  closing  of the
transaction were directors or managers of BT immediately prior to the closing of
the  transaction,  or (y) less  than 50% of the  voting  power of the  surviving
parent entity  immediately  following the closing of the  transaction is held by
persons  who were  stockholders  of BT  immediately  prior to the closing of the
transaction,  (ii) sale,  transfer or other  disposition of all or substantially

under the Code, and shall otherwise  comply with the requirements of such Income

for book purposes and allocations of income,  gain,  loss,  deduction and credit
for U.S. federal income tax purposes.

     (d)  Allocations.  Profits and losses  shall be allocated so the amounts of
any  distributions are in accordance with the capital accounts of the persons to
whom such distributions are made. Notwithstanding the foregoing,  allocations of
income,  gain,  loss,  deduction and credit for U.S. federal income tax purposes
shall be made in  accordance  with  Section 704 of the Code and the  Regulations

effect  as that  term is used in the  Code and  Regulations.  In  addition,  the
provisions  of Section  704(c) and 721(c) of the Code shall apply so that (i) in
the event that the capital account of any person is credited with or adjusted to
reflect the fair market value of an asset (including, without limitation, the BT
Stock),  the  distributive  share of gain or loss, as computed for tax purposes,
with respect to such property, shall be determined pursuant to Section 704(c) of
the Code and the Regulations thereunder,  so as to take account of the variation
between the adjusted tax basis and fair market value of such property,  and (ii)
any gain realized on the transfer of property  (including,  without  limitation,
the BT Stock) to Offshore  Newco (or any entity within the Newco Group) by BT or
BTFE will, when recognized,  be includable in the gross income of BT or BTFE, as
appropriate.

     (e) Modification of Structure.  If the provisions of this Section 10 cannot
be complied with or if the transactions  contemplated by this JV Agreement would
(after  consultation  with BT's legal and tax advisors)  result in BT having any
significant adverse tax consequences (including, without limitation, recognition
of gain on the  contribution  of BT Stock or other property to Offshore Newco or
an entity  within the Newco  Group),  the parties  hereto  agree to cooperate in
restructuring  the proposed  transaction  to minimize or eliminate  such adverse
consequence  in such manner as preserves,  to the fullest extent  possible,  the
economic benefits intended to be afforded to each of the parties.

     11. Compliance with U.S. Laws.

     (a) The U.S.  Foreign Corrupt  Practices Act (the "FCPA") makes it unlawful
for BT, or any BT agent or other third  party  acting on behalf of BT, to offer,
pay, promise or authorize to pay any money, gift or anything of value, including
but not limited to bribes, entertainment,  kickbacks or any benefit, directly or
indirectly,  (i) to any foreign official or any foreign  political party or (ii)
to any person  while  knowing  or  suspecting  that the  payment or gift will be
passed on to a foreign official, in connection with any business activity of BT;
provided, however that the foregoing preclusions do not apply to facilitating or
expediting  payments to a foreign  official,  political party, or party official
the purpose of which is to expedite or to secure the  performance  of a "routine
governmental action" by a foreign official, political party or party official.

     (b) For the purpose of this JV Agreement,  (i) a "foreign  official"  means
any employee or officer of the  government of a foreign  country,  including any
federal, regional or local department, agency, instrumentality, enterprise owned
or controlled by the government of a foreign country,  any official of a foreign
political   party,   any   official  or  employee  of  a  public   international
organization,  any person  acting in an official  capacity for, or on behalf of,
such entities, and any candidate for foreign political office; and (ii) the term
"routine  governmental  action"  means only an action  which is  ordinarily  and
commonly performed by a foreign official in (A) obtaining permits,  licenses, or
other  official  documents  to  qualify  a person  to do  business  in a foreign
country; (B) processing  governmental papers, such as visas and work orders; (C)
providing  police   protection,   mail  pick-up  and  delivery,   or  scheduling
inspections  associated  with contract  performance  or  inspections  related to
transit of goods across country;  (D) providing  phone service,  power and water
supply,  loading and  unloading  cargo,  or  protecting  perishable  products or
commodities from deterioration; or (E) actions of a similar nature.

     (c)  Master   Gain   agrees  and   acknowledges   that  BT  and  its  legal
representatives  have explained the  requirements  and prohibitions of the FCPA,
and  that  those  Master  Gain  directors,   officers,   employees,  agents  and
representatives  acting  on  BT's,  Offshore  Newco's,  China  Newco's,  or  any
Additional  Entity's behalf  understand those  requirements and prohibitions and
will comply therewith. Master Gain shall advise and explain the requirements and
prohibitions  of the  FCPA to each new  director,  officer,  employee,  agent or
representative  that  will act on BT's,  Offshore  Newco's,  China  Newco's  any
Additional Entity's behalf.

     (d) Master Gain agrees  that  should BT  reasonably  and in good faith have
concerns  that there has been a  violation  of this  Section,  Master Gain shall
cooperate  in good faith  with BT to  determine  whether  such a  violation  has
occurred. If BT determines reasonably and in good faith that there has been such
a violation and can provide  evidence  supporting such  determination,  it shall
have the right to terminate  this JV Agreement  and the Venture  pursuant to the
terms of Section 15(a) with immediate effect. If termination  occurs pursuant to
this  Section,  BT  shall be  relieved  of any  further  obligations  under  the
Agreement.

     (e) Master Gain shall  supply to BT all  information  and  records  that BT
determines, in its sole discretion,  are needed to enable BT to comply or verify
compliance with U.S. laws and regulations.

     (f) China  Newco,  at its own  expense,  shall  indemnify  and hold BT, its
directors,  officers,  employees, agents, subsidiaries,  affiliates,  customers,
designees,  and assignees harmless from any loss, damage,  liability or expense,
on account of any failure to comply with the terms of this JV  Agreement or with
the laws and  regulations  of the  Government the United States arising from any
occurrence  caused by any act or omission of Master Gain,  Offshore  Newco,  any
Additional  Entity  or  China  Newco  related  to the  performance  of  this  JV
Agreement.  China Newco, at its expense, shall defend any suit or dispose of any
claim or other  proceedings  brought against said indemnities on account of such
damage or injury,  and shall pay all expenses,  including  attorney's  fees, and
satisfy  all  judgments  which  may be  incurred  by or  rendered  against  said
indemnities.

     12. Options.  Upon payment of the Master Gain Investment to Offshore Newco,
consummation of the sale of the CMTS Assets to Offshore  Newco,  and approval of
the Venture by BT's  primary  lenders,  BT will grant to Master Gain  options to
purchase  up to 500,000  shares of  unregistered  BT common  stock  (the  "Stock
Options").  The exercise  price of the Stock  Options,  payable in cash ("Strike
Price"),  and the vesting  schedule of such Stock  Options will be in accordance
with the  following  schedule (i) options to purchase  50,000 shares at a Strike
Price of $5.00  per share  will  vest at such  time as Master  Gain has made its
capital contributions to Offshore Newco contemplated by Section 4 herein and has
sold and  transferred  the CMTS Assets to Offshore Newco and expire on September
30, 2008, (ii) options to purchase 150,000 shares at a Strike Price of $7.00 per
share  will vest on April 15,  2007 and  expire  on April  14,  2010,  and (iii)
options to purchase  300,000  shares at a Strike  Price of $10.00 per share will
vest on April 15, 2008 and expire on April 14, 2011; provided, however, that for
each fiscal year of BT commencing with 2006, as and to the extent that the Newco
Group  incurs  a loss in any  fiscal  year  that is  reflected  in or  otherwise
adversely  impacts  the  income  statement  of BT by  virtue  of BT's  ownership
interest  therein  (whether under the equity method or as part of a consolidated
group  with BT),  such  number of Stock  Options  as equals  the  amount of loss
recognized or to be recognized by BT divided by the Strike Price, will be deemed
cancelled and  terminated,  with the first Stock Options to vest being the first
Stock Options to be cancelled and terminated.  Stock Options, once exercised and
full  consideration  paid (and the  shares  of stock  issued  upon the  exercise
thereof) will not be subject to cancellation pursuant to the foregoing sentence.
In illustration of the foregoing,  if BT recognizes a loss of $100,000 in fiscal
year 2006 attributable to the Newco Group,  20,000 of Master Gain's  unexercised
Stock  Options  that  vested  as set  forth in  subsection  (i)  above  would be
terminated and cancelled.  In the event that this JV Agreement is terminated for
any reason,  including  termination of the Venture  pursuant to Section 15(a) or
(b), within the three (3) year period  immediately  following the Effective Date
of this JV Agreement,  then all unvested Stock Options then outstanding shall be
cancelled and terminated.  In the event of a Change in Control Transaction,  all
unvested Stock Options  outstanding  as of the closing date of such  transaction
shall be  cancelled  and  terminated.  The  provisions  of this  section will be
applied  independently  of the  provisions  of section  6(e)  relating to the BT
Stock.

     13. Governance.  Except as the PRC Laws otherwise require, each of Offshore
Newco and China Newco shall have the following governance structure.

     (a) Election of Directors.  Each of Offshore Newco and China Newco shall be
managed by a board of directors (or other  applicable  governing  body).  Master
Gain,  BTFE and  Offshore  Newco,  as  applicable,  shall  enter into  operating
agreements  related to Offshore  Newco and China  Newco,  pursuant to which each
would  agree to vote their  equity  interests  in such a manner as to cause each
board of directors  to be comprised of six (6) members,  three (3) of whom shall
be nominees of and  elected by BTFE (the "BT  Directors")  and three (3) of whom
shall be nominees of and elected by Master Gain (the "Master Gain Directors").

     (b) Voting,  Quorum and Actions.  Each  director on each board of directors
shall be entitled  to one (1) vote on each  matter to properly  come before such
board of directors.  The quorum required for each properly  convened  meeting of
each board of directors shall be four (4) directors,  provided, however, that at
least  two of such  directors  are BT  Directors  and at  least  two (2) of such
directors are Master Gain  Directors.  All  resolutions  shall be adopted by the
affirmative  vote of at least  two-thirds  of the  directors in  attendance at a
properly convened meeting.

     (c) Managing Directors.  Each Board shall elect two Managing Directors, one
of whom shall be selected by the BT Directors  and one of whom shall be selected
by the Master Gain Directors.  Initially,  it is contemplated  that the managing
director  selected by the BT  Directors  would be Robert J. Palle,  Jr., and the
managing  director  selected by the Master Gain Directors would be Eyal Lior. It
shall be a condition to the  appointment of any managing  director that is not a
citizen of PRC, that they waive any claim or right  available  under the laws of
the PRC resulting  from their loss of office or employment  upon  termination of
the  Venture  or upon a buyout by one party or the  other,  as  contemplated  by
Section 15 herein.

     (d)  Officers.  Each Board of Directors  may from  time-to-time  elect such
other officers of Offshore Newco or China Newco, as applicable, as it shall deem
necessary or appropriate.  Subject to the agreement of both managing  directors,
each managing  director  shall have the authority to sign any and all agreements
and other  documents  in  connection  with  Offshore  Newco or China  Newco,  as
applicable.

     (e) Budget.  The  Managing  Directors  of each of Offshore  Newco and China
Newco  shall  prepare an annual line item  operating  budget for such entity for
each fiscal  year,  prepared at least sixty (60) days prior to the start of each
fiscal  year,  which budget shall set forth,  on a monthly  basis,  all receipts
projected  for the fiscal year and all  expenses,  by  category,  including  any
capital expenditures,  for the fiscal year ("Annual Budget").  The Annual Budget
must be approved by the Board of  Directors  of Offshore  Newco and China Newco,
respectively,  and may be  revised  from time to time upon the  approval  of the
Board  of  Directors,  but no  more  frequently  than  quarterly.  The  Managing
Directors shall only have authority for  expenditures  within the Annual Budget.
Any  expenditure  in excess of five  percent  (5%) of the line  amount  budgeted
therefor  in the  Annual  Budget  shall  require  the  approval  of the Board of
Directors.

     (f) Dispute Resolution.

          (i) Each of the Managing  Directors and the Boards of Directors  shall
     use their  good faith best  efforts to agree and  compromise  on each major
     decision; provided, however, that in the event agreement cannot be obtained
     for a major  decision  resulting in a stalemate or deadlock among the Board
     of Directors or Managing  Directors of either Offshore Newco or China Newco
     that would have a material adverse effect on its business, either party may
     give notice to the other of such major  decision.  Within  twenty (20) days
     after  delivery of such notice,  executives  of each party  involved in the
     controversy  shall  meet at a  mutually  acceptable  time  and  place,  and
     thereafter as often as they reasonably deem necessary, to exchange relevant
     information  and to attempt to resolve the  dispute.  If the matter has not
     been resolved within sixty (60) days of the disputing party's notice, or if
     the parties  fail to meet within  twenty (20) days of such  notice,  either
     party may initiate  mediation of the  controversy as provided  below.  If a
     negotiator intends to be accompanied at a meeting by an attorney, the other
     negotiator(s)  shall be given at least three  working  days' notice of such
     intention  and may also be  accompanied  by an attorney.  All  negotiations
     pursuant  to this  Section  shall be  confidential  and shall be treated as
     compromise and settlement negotiations for purposes of the U.S. federal and
     state rules of evidence.

          (ii) If the  controversy  has not  been  resolved  by  negotiation  as
     provided  above,  the parties shall  endeavor to settle the  controversy by
     mediation  under the  then-current  CPR  Institute  for Dispute  Resolution
     ("CPR")   (www.cpradr.org)   Model  Procedure  for  Mediation  of  Business
     Disputes.  The neutral  third party will be selected from the CPR Panels of
     Neutrals.  If the parties  encounter  difficulty  in agreeing on a neutral,
     they will seek the assistance of CPR in the selection process.  The parties
     shall agree upon a mutually  acceptable  time and place for each  mediation
     session  and, if unable to do so, the  mediator  shall  decide the time and
     place.  The costs of the mediation  shall be shared equally by the parties.
     Efforts to reach a settlement  will  continue  until the  conclusion of the
     mediation  proceeding,  which  is  deemed  to  occur  when:  (a) a  written
     settlement  is  reached,  or (b) the  mediator  concludes  and  informs the
     parties in writing that  further  efforts  would not be useful,  or (c) the
     parties  agree in writing  that an impasse has been  reached.  No party may
     withdraw before the conclusion of the proceeding.  The parties shall regard
     this obligation to mediate as an essential  provision of the organizational
     documents governing the structure and governance of Offshore Newco or China
     Newco, as applicable, and one that is legally binding on them. In case of a
     violation  of such  obligation  by one party,  any other party may bring an
     action to seek  enforcement  of such  obligation in any court of law having
     jurisdiction thereof.

          (iii) If the  controversy  has not been  resolved  by  negotiation  or
     mediation as provided  above,  the parties shall settle the  controversy by
     arbitration  under the  then-current  CPR Commercial  Arbitration  Rules by
     three neutral arbitrators.  Each party shall appoint one neutral arbitrator
     and these two arbitrators  shall appoint the third. The governing law shall
     be as defined in Paragraph 26 of this JV Agreement; the parties acknowledge
     that the organizational documents governing the structure and governance of
     Offshore  Newco or China  Newco,  as  applicable,  evidences a  transaction
     involving   international   commerce,   however,   and  the  United  States
     Arbitration Act, 9 U.S.C. §§ 1 et seq.,  shall govern the   interpretation,
     enforcement,  and proceedings pursuant to the arbitration clause in this JV
     Agreement.  The arbitration shall be in the English language, and the place
     and time of the  arbitration  shall be mutually  acceptable to the parties;
     absent agreement,  the place shall be Trenton, New Jersey,  U.S.A., and the
     parties  consent  to the  personal  jurisdiction  of the state and  federal
     courts there for any  controversy  arising out of or  otherwise  related to
     this arbitration,  its conduct, and its enforcement.  The arbitrators shall
     make a reasoned  award which shall be  binding,  final,  and not subject to
     appeal.  Judgment upon the award rendered by the arbitrators may be entered
     in any court of law having jurisdiction  thereof. Each party shall bear its
     own  costs  and  expenses  and  an  equal  share  of the  arbitrators'  and
     administrative fees of the arbitration

          (iv) The parties, their representatives,  other participants,  and the
     mediator and arbitrators shall hold the existence,  content,  and result of
     mediation and  arbitration in  confidence.  A request by a party to a court
     for  interim  measures  shall not be deemed a waiver of the  obligation  to
     mediate and arbitrate

          (v) The parties  shall agree on the nature of those  matters that will
     be considered "Major Decisions" in the organizational  documents  governing
     the  structure  and  governance  of  Offshore  Newco  or  China  Newco,  as
     applicable,  provided,  however,  that such term shall include any proposed
     action by Offshore Newco or China Newco that is beyond its ordinary  course
     of business,  results in expenditures in excess of the approved budget,  or
     causes the incurrence of liabilities in excess of the budget.

     (e)  Unavailability of Governance  Structure.  To the extent the governance
structure  set forth in this Section 13 is not  available  due to any PRC Law or
other  applicable law, the parties shall work together to determine a governance
structure  that  complies  with all  requirements  of the PRC Law or such  other
applicable law, provided,  however,  that any governance structure selected must
be approved by both BTFE and Master Gain.

     14. Dispute Resolution.

     (a) Each of the parties hereto,  including Offshore Newco, China Newco, any
Additional  Entity and any other  entity  that  shall  become a party to this JV
Agreement  shall use their good faith best efforts to agree and  compromise  any
questions,  issues or disputes  (each a "Dispute")  arising out of or related to
this JV  Agreement.  Any party may give  notice to the other  parties  of any of
Dispute not resolved in the normal  course of business.  Within twenty (20) days
after delivery of such notice,  executives of each party involved in the Dispute
shall meet at a mutually  acceptable time and place,  and thereafter as often as
they reasonably deem necessary,  to exchange relevant information and to attempt
to resolve the Dispute.  If the matter has not been  resolved  within sixty (60)
days of the  disputing  party's  notice,  or if the parties  fail to meet within
twenty (20) days of such  notice,  either  party may  initiate  mediation of the
controversy as provided  below.  If a negotiator  intends to be accompanied at a
meeting by an attorney,  the other  negotiator(s)  shall be given at least three
working  days'  notice  of such  intention  and may  also be  accompanied  by an
attorney.  All  negotiations  pursuant to this Section shall be confidential and
shall be treated as compromise and settlement  negotiations  for purposes of the
U.S. federal and state rules of evidence.

     (b) If the Dispute has not been resolved by negotiation as provided  above,
the  parties  shall  endeavor  to settle  the  Dispute  by  mediation  under the
then-current CPR Institute for Dispute Resolution ("CPR") (www.cpradr.org) Model
Procedure  for Mediation of Business  Disputes.  The neutral third party will be
selected from the CPR Panels of Neutrals. If the parties encounter difficulty in
agreeing on a neutral,  they will seek the  assistance  of CPR in the  selection
process.  The parties shall agree upon a mutually  acceptable time and place for
each  mediation  session and, if unable to do so, the mediator  shall decide the
time and  place.  The  costs of the  mediation  shall be shared  equally  by the
parties. Efforts to reach a settlement will continue until the conclusion of the
mediation proceeding, which is deemed to occur when: (a) a written settlement is
reached,  or (b) the mediator  concludes and informs the parties in writing that
further efforts would not be useful, or (c) the parties agree in writing that an
impasse has been  reached.  No party may withdraw  before the  conclusion of the
proceeding.  The parties shall regard this obligation to mediate as an essential
provision of this JV Agreement, and one that is legally binding on them. In case
of a violation  of such  obligation  by one party,  any other party may bring an
action  to seek  enforcement  of such  obligation  in any  court  of law  having
jurisdiction thereof.

     (c) If the Dispute has not been  resolved by  negotiation  or  mediation as
provided  above,  the parties shall settle the Dispute by arbitration  under the
then-current CPR Commercial Arbitration Rules by three neutral arbitrators. Each
party shall  appoint  one neutral  arbitrator  and these two  arbitrators  shall
appoint the third. The governing law shall be as defined in Paragraph 26 of this
JV  Agreement;  the  parties  acknowledge  that this JV  Agreement,  evidences a
transaction  involving  international  commerce,  however, and the United States
Arbitration  Act,  9 U.S.C.  §§ 1 et seq.,  shall  govern  the   interpretation,
enforcement,  and  proceedings  pursuant  to the  arbitration  clause in this JV
Agreement.  The arbitration shall be in the English language,  and the place and
time of the  arbitration  shall be mutually  acceptable  to the parties;  absent
agreement,  the place shall be  Trenton,  New  Jersey,  U.S.A.,  and the parties
consent to the personal  jurisdiction  of the state and federal courts there for

          (iv) The parties, their representatives,  other participants,  and the
     mediator and arbitrators shall hold the existence,  content,  and result of

     for  interim  measures  shall not be deemed a waiver of the  obligation  to

Master Gain's equity ownership percentage of Offshore Newco, payable by delivery
of a  promissory  note  for the  purchase  price  thereof  payable  in 20  equal
consecutive  quarterly  installments,  bearing interest at the lowest applicable

quarterly  installments,  bearing interest at the lowest applicable federal rate
of interest  necessary to avoid the imputation of interest under applicable U.S.

interest under applicable U.S. Law, (b) the then existing manufacturing, license
and distribution  agreements  between or among BT, BTFE,  Master Gain,  Offshore
Newco,  China Newco and any  Intermediate  Entity or Additional  Entity shall be
terminated,  (c) BT shall have the right to cancel all BT Stock held by Offshore
Newco or  China  Newco on the  date of  termination,  and (d) BT shall  grant to
Offshore  Newco,  China Newco and/or any Additional  Entity,  as  applicable,  a
limited,  non-exclusive  license for a term to be negotiated (with  revocability
triggered by failure to maintain specified performance  standards) to use the BT
Licensed  Technology  for the  manufacture  and sale of products  into the Newco
Markets to be agreed upon by the parties,  with such royalty  payments and other
terms as may be  negotiated  between the  parties;  provided,  however,  that if
either party gives notice of termination of the Venture as  contemplated in this
Section 15(b), but neither party agrees to purchase the other party's  ownership
interest in Offshore Newco,  as contemplated by clauses (i) or (ii) above,  then

manufacturing,  marketing  or selling the  Specified  BT  Products or  otherwise
exploiting any BT  Intellectual  Property and (d) each of China Newco,  Offshore
Newco and any Additional Entity shall be dissolved.

such royalty payments and other terms as may be negotiated  between the parties;
provided,  however,  that if either  party gives  notice of  termination  of the
Venture as  contemplated  in this  Section  15(d),  but neither  party agrees to
purchase the other party's ownership interest in Offshore Newco, as contemplated
by clauses (i) or (ii) above, then (a) the existing  manufacturing,  license and

     (e) Right of First Refusal.  After five (5) years from the Effective  Date,
if either BTFE or Master Gain (the "Selling  Party")  receives a bona fide offer
to purchase  all, but not less than all, of its  ownership  interest in Offshore
Newco,  which it desires to accept,  such Selling Party must first offer to sell
such ownership  interest to the other party (the "Non-Selling  Party") by giving
written notice of the offer,  including the offer price and offer terms,  to the
Non-Selling  Party  (the  "Offer  Notice").  Except  with  the  consent  of  the
Non-Selling Party, the Offer Notice shall be irrevocable.  The Non-Selling Party
shall have a period of thirty  (30) days from the date of the Offer  Notice (the
"Acceptance  Period") to exercise  its right to purchase  all, but not less than
all, of the Selling Party's ownership interest pursuant to the Offer Notice, for
the offer  price and on the  offer  terms.  If the  Non-Selling  Party  does not
exercise its option to purchase the Selling  Party's  ownership  interest during
the Acceptance  Period,  the Selling Party may, for a period of ninety (90) days
from the termination of the Acceptance  Period,  sell such ownership interest to
any third party ("Purchaser") for not less than the offer price and on the offer
terms,  provided,  however,  that (i) the  Non-Selling  Party shall approve such
Purchaser, which approval shall not be unreasonably withheld, (ii) the Purchaser
shall agree to become a party to this JV Agreement and assume all of the Selling
Party's obligations hereunder, (iii) the Purchaser shall agree to become a party
to such of the Venture Agreements as the Non-Selling Party deems necessary,  and
(iv)  the  purchase  and sale of such  ownership  interest  does not  materially
adversely  affect the Non-Selling  Party,  Offshore Newco or any other entity in
the Newco Group.  The parties  shall cause the  Directors  of Offshore  Newco to
unanimously approve the purchase of the ownership interest by the Purchaser.  In
the event that BTFE is the Selling Party, (i) BT shall be entitled,  in its sole
discretion,  to cancel any shares of BT Stock held by Newco Group as of the date
of the  transaction  and, in  consideration  thereof,  pay to Offshore Newco the
Valuation  Amount,  calculated as of the Valuation  Date, (ii) the then existing
manufacturing,  license and distribution  agreements  between or among BT, BTFE,
Master Gain,  Offshore Newco,  China Newco and/or any Additional Entity shall be
terminated as of the date of the transaction,  and (iii) BT shall grant Offshore
Newco,  China Newco and/or any  Additional  Entity,  as  applicable,  a limited,
non-exclusive  license for a term to be negotiated (with revocability  triggered
by failure to maintain specified  performance  standards) to use the BT Licensed
Technology for the manufacture and sale of products into the Newco Markets to be
agreed upon by the parties, with such royalty payments and other terms as may be
negotiated between the parties.

     (f) Indemnification.  In the event either BTFE's or Master Gain's ownership
interest  in Offshore  Newco is  purchased  by the other  party  pursuant to any
provision of this Section 15, the selling party's elected directors shall resign
from the board of directors and all other  positions of both Offshore  Newco and
China Newco and, in connection with such  resignations,  the selling party shall
indemnify the purchaser against any claim brought by such director in connection
with the loss of office or employment.

     (g) Approval.  In the event that either  BTFE's or Master Gain's  ownership
interest  in Offshore  Newco is  purchased  by the other  party  pursuant to any
provision of this Section 15, both parties  shall work together to apply for and
obtain any consent or approval  required for such  purchase by any  governmental
authority pursuant to applicable law.

     16.  Accounting  Functions.  The  parties  agree that BT shall  manage,  in
accordance with generally accepted accounting  principals  consistently  applied
("GAAP"),  all financial reporting and accounting functions for the Newco Group,
including,  without limitation, all internal controls and compliance and receipt
of all cancelled checks;  provided,  however,  that the  check-writing  function
shall be managed by the Managing  Directors of each of Offshore  Newco and China
Newco,  under the guidance of their respective Boards of Directors.  Each entity
within the Newco Group shall adopt the United States  Dollar as the  bookkeeping
base  currency,  but may also  use  other  foreign  currencies  as  supplemental
bookkeeping currencies. All bank accounts opened for Offshore Newco, China Newco
and/or  any  Intermediate  Entity  or  Additional  Entity,  will  be  with  such
international banking institutions,  as BT shall determine,  that, to the extent
possible,  have  operations  in the United States as well as in China and in the
domiciliary jurisdiction of Offshore Newco. To the fullest extent allowed by PRC
Law, all accounts shall be held in United States  Dollars.  The parties agree to
work  together to apply for and obtain any consent or approval  required to open
accounts with such banking institutions  required by any governmental  authority
pursuant to  applicable  law. BT shall be permitted  to charge a reasonable  and
appropriate  portion  of its  administrative  overhead  to the  Newco  Group  as
consideration for the provision of such accounting  functions and oversight (the
"Services Fee"), and the parties shall cooperate to the fullest extent necessary
to obtain any approval  required  for the payment of such  Services  Fee.  Newco
Group's  financial  statements shall be audited as and to the extent required by
United States securities laws by virtue of BT's ownership  interest therein,  by
an accounting firm acceptable to the BT Directors. To the fullest extent allowed
by applicable law, such accounting firm shall audit all other matters  relating,
directly or indirectly,  to the financial condition of Newco Group. All fees for
such  accounting  firm shall be paid by Newco Group.  Newco Group shall,  to the
extent  requested  by BT,  cooperate  with BT to  provide  such  information  as
required by BT to  reconcile  Newco  Group's  financial  statements  with United
States GAAP  reporting  requirements.  China  Newco may be further  audited by a
statutory auditor as may be required by any PRC Law.

     17. Manufacturing  Services Agreement.  BT shall enter into a manufacturing
services  agreement  with  China  Newco  pursuant  to which  China  Newco  shall
manufacture the Specified BT Products for such price and on such other terms and
conditions as may be mutually agreed to between the parties.

     18. Distribution Agreements.

     (a) China Distributorship. BT and entities comprising the Newco Group shall
enter into  distributorship  agreements  as provided in Section  2(a)(v)  above,
pursuant  to which BT shall  grant to  entities  comprising  the Newco Group (as
determined by the parties) the Newco Distributorship which shall be an exclusive
distributorship within the Newco Markets for the term of the Venture.

     (b) BT  Distributorship.  BT and entities  comprising the Newco Group shall
enter into  distributorship  agreements as provided in Section 2(a)(viii) above,
pursuant to which China Newco or other entities comprising the Newco Group shall
grant BT the BT  Distributorship  which  shall be an  exclusive  distributorship
within the BT Markets for the term of the Venture.

     (c) Gross  Profit  Margin.  Each  distributorship  agreement  (or series of
distributorship  agreements,  as the case may be) shall  provide that each party
shall sell their  respective  products to the other for resale within such other
party's markets (as set forth in Secti on 2), at such prices as shall permit the
Newco  Group on the one hand and BT on the other  hand to obtain a gross  profit
margin of thirty percent (30%);  provided,  however, that if and to the extent a
particular  product suffers from downward price competition at the resale level,
the parties shall negotiate a reasonable  adjustment to the thirty percent (30%)
gross  profit  margin.  All other  terms  and  conditions  of such  distribution
agreements shall be as mutually agreed to between the parties.

     19. Yitong Venture.

     (a) The  parties  acknowledge  and agree that it will take a period of time
until China Newco has acquired or constructed the Manufacturing Facility capable
of performing  its intended  functions.  To facilitate  the parties'  ability to
obtain  certain  of the  benefits  contemplated  by  this  JV  Agreement,  it is
anticipated that Offshore Newco shall enter into a joint venture  agreement with
an entity  formed  under the laws of Hong Kong  ("Yitong  Hong Kong") and wholly
owned by Jiangsu Yitong High Tech Co. Ltd., a corporation  formed under the laws
of the PRC,  based on which these two entities  form a new wholly  foreign-owned
enterprise  under  the  laws of the PRC  ("Yitong/Newco  Venture"),  having  the
following equity structure:

                               Equity Ownership           Initial Cash
                             and Economic Interest    Capital Contribution
 Offshore Newco                     50%                    US$1,200,000
 Yitong Hong Kong                   50%                    US$1,200,000

     (b) To the extent the equity  structure set forth in this Section 19 is not
available  due to any PRC Law,  the parties  shall work  together to determine a
equity structure that complies with all  requirements of the PRC Law,  provided,
however,  that any equity  structure  selected must be approved by both BTFE and
Master Gain.

     (c) Each of BTFE and  Master  Gain  shall  work  with  Yitong  Hong Kong to
develop a governance  structure for Yitong/Newco  Venture that complies with all
requirements of the PRC Law,  including all provisions related to dissolution of
the  Yitong/Newco  Venture,  provided,  however,  that any governance  structure
selected must be approved by both BTFE and Master Gain.

     (d) Certain Specified BT Products,  Newco Products and third party products
(collectively,  the  "Products")  to be  manufactured  by China  Newco  shall be
subcontracted by China Newco to Yitong/Newco Venture pursuant to a manufacturing
services  agreement between China Newco and Yitong/Newco  Venture.  Yitong/Newco
Venture shall contract  manufacture  the Products for China Newco at such prices
as would permit Yitong/Newco Venture to obtain a maximum gross margin of 11%. It
is  envisioned  that as China  Newco's  manufacturing  capability  is developed,
Yitong/Newco   Venture  shall  continue  to  manufacture  the  Products  at  the
experienced volumes (the parameters of which shall be mutually agreed to between
the parties) and China Newco shall  manufacture  quantities  of such Products in
excess of these experienced volumes as the sales volume develops.

     20. Venture Agreements.

     (a) Each of the parties  hereto  shall use their good faith best efforts to

permits,  licenses and other authorizations required or desirable to achieve the

executed within six (6) months following the Effective Date of this JV Agreement
or (ii) the  Approvals  and  Licenses  are not  obtained  within  six (6) months
following the Effective  Date of this JV Agreement,  then for a period of thirty
(30) days after the expiration of such six (6) month period, either BT or Master
Gain shall have the right to  terminate  the  Venture and this JV  Agreement  by
sending written notice of this election to the other party. Upon receipt of such

(iv) BT and Master Gain shall cause  Offshore Newco to distribute to Master Gain
the Master Gain  Investment,  net of all expenses and fees incurred prior to the

contributions  as set forth in  subsection  (iii)  above,  (v) BT shall have the
right to cancel all BT Stock held by Offshore Newco or China Newco, and (vi) all
unexercised Stock Options shall be cancelled and terminated.

     21.  Confidentiality.  The parties  hereto  agree,  except as disclosure is
required by applicable law, to maintain this JV Agreement, their discussions and
negotiations  that are the  subject  of this JV  Agreement,  and all  subsequent
correspondence  in the strictest  confidence;  provided,  however,  that nothing
herein shall prohibit any party from discussing the matters contemplated in this
JV Agreement with its bankers, accountants,  lawyers and other advisors who have
a need to  know.  In no  event  shall  Master  Gain,  or any  person  or  entity
affiliated  with,  or  related  to,  Master  Gain,  (i) use any BT  Intellectual
Property for any purpose without BT's prior written consent, (ii) challenge,  or
assist any other person to challenge,  the  proprietorship of BT, or (iii) apply
for registration of any of the BT Intellectual Property in any part of the world
(if capable of registration).
