computers including display monitors, liquid crystal display panels, CD-ROM
drives, hard disk drives, static, video and dynamic random access memory, and
other items which exist now or may be developed in the future (the "Products").

AST and SEC wish to develop an improved supplier to customer relationship, with
SEC gaining a dependable customer for large quantities of SEC Products in a cost
efficient way, and with AST gaining a dependable source for certain of SEC's
Products on favorable terms.

                                   AGREEMENT

     --------------------                                                   
     treated as confidential information, relating to the Product needs of AST
     and the ability of SEC to supply Products to AST.

Article 2.  Ordering

2.1  Procedures.  Unless otherwise agreed between the parties the ordering
     ----------

     SEC of anticipated purchases of the Products, and shall update the forecast
     monthly. This forecast shall not be a commitment of either AST or SEC, but
     is necessary for the planning purposes of AST and SEC and their mutual
     convenience.  Unless otherwise agreed by both SEC and AST, and subject to
     the provision of Article 3 of this Agreement, the immediate three (3)
     month forecast shall

     the Ordering Entity pursuant to the terms and conditions of this Agreement.

     with at least sixty (60) days lead time for delivery during the term of
     this Agreement.  SEC agrees to bear any expedited shipping costs or other
     costs required to meet any previously committed SEC delivery dates or to
     recover from delays.  Any such purchase orders shall constitute separate
     contracts between SEC and the Ordering Entity.

Article 3.  Pricing, Quantity, Terms and Conditions

     Agreement shall supersede such terms and conditions.

     be assigned by either party without the express written

                                       2
<PAGE>
 
     consent of the other party in each instance.  The provisions included in
     the General Terms Agreement shall apply to this Agreement.

<PAGE>
 
     manufacturing of the Products as agreed upon in writing by both of the
     parties prior to the commencement of any Product manufacturing tasks
     (the "Product Plan").  The parties will carry out their responsibilities
     within the time frames set forth in such Product Plan.

2.2  Product Specifications.  AST and SEC shall both approve the product
     ----------------------                                             
     specifications described in Article 1.1 hereof. AST may change the
     specifications of the Product, provided that reasonable advance written
     notification is given to SEC, and that such changes to the specification do
     not change the form, fit and functional performance of the Product.  In
     addition, AST may change the specifications of the Product even if such

     charges incurred by AST in connection with the development of the Product,
     provided that the amount of such Non-Recurring Engineering charges are
     included in the written Product Plan or otherwise approved in advance in
     writing by SEC, and provided that any increases to such Non-Recurring
     Engineering charges are approved in advance by SEC.

2.4  Right of First Refusal.  AST shall have a right of first refusal to develop
     ----------------------                                                     
     (under appropriate separate terms) or manufacture any Products for SEC
     following the Effective Date hereof, subject to the terms of this
     Agreement.  When SEC determines to seek an outside source of supply for
     Products, SEC shall provide information to AST concerning such Products
     when and to the extent that such information is provided to other potential
     outside sources.  AST shall, at its option, provide a quotation to SEC for
     the development or manufacturing of such Products.  Prior to entering into
     any agreement with a third party to provide SEC with such Products, SEC
     shall provide written notice to SEC of the terms and conditions of the
     proposed arrangement in sufficient detail to enable AST to evaluate the
     same (the "Contemplated Transaction").  To exercise its right of first
     refusal, AST shall advise SEC of its intent to exercise its right of first
     refusal, in writing, at any time within the fourteen (14) business days
     following AST's receipt of such notice (the "Exercise Period").  If AST
     wishes to exercise its right of first refusal, AST shall provide a written
     quotation to SEC for the Products with all terms, conditions,
     specifications, quality requirements, prices, allocations, and other
     provisions at least as favorable as were offered to SEC in the Contemplated
     Transaction.  If AST notifies SEC that it does not wish to exercise its
     right of first refusal or fails to respond to SEC in writing within the
     Exercise Period (the "OEM Project Rejection") then SEC shall be free to
     enter into the Contemplated Transaction on

                                       2
<PAGE>
 
     the same terms and conditions as offered to AST; provided, however,
     that if the Contemplated Transaction is not entered into in writing
     between SEC and a third party within six (6) months of the OEM Project
     Rejection then AST's right of first refusal shall be revived with
     respect to the OEM product and technology related to the Contemplated
     Transaction and SEC shall offer the OEM product and technology
     related to the Contemplated Transaction to AST in accordance herewith prior
     to entering into any arrangement related to such OEM product or technology
     with any third party.


Article 3.  Technology Sharing

     In recognition of the advanced development nature of technology
     contemplated by the development of the Products, it is anticipated that AST
     and SEC will find it mutually beneficial to establish a close working
     relationship to exchange Technical Information to achieve the objectives of
     this Agreement.  Toward this end, the parties hereby agree to, within the
     confines of applicable law, provide each other with sufficient Technical
     Information to accomplish the purposes of each Product Plan adopted
     pursuant to this Agreement.  Any and all such Technical Information
     exchanged pursuant to this Agreement shall be treated as Confidential
     Information in accordance with the terms and conditions of that certain
     General Terms Agreement between the parties of even date herewith.


Article 4.  Proprietary Rights

4.1  Separately Owned Rights.  Any Technical Information which is developed or
     -----------------------                                                  
     conceived independently by each party hereunder and Intellectual Property
     Rights therefor shall remain the property of such developing party.

4.2  Jointly Owned Rights.  Any Technical Information which is developed or
     --------------------                                                  
     conceived jointly by both parties hereunder and Intellectual Property
     Rights therefor shall be the joint property of both parties. Each party
     shall have a right to grant to its Subsidiaries the licenses under jointly
     owned Technical Information and Intellectual Property Rights therefor
     without obtaining a prior consent of and accounting for any compensation to
     the other party. The party who wishes to grant to any third party any
     licenses under the jointly-owned Technical Information and any Intellectual
     Property Rights therefor shall obtain a prior written approval of the other
     party. Notwithstanding any other provision hereof, the parties agree that
     any Technical Information or Intellectual Property Rights related to any

                                       3
<PAGE>
 
     development by AST in connection with the development of the Product to
     satisfy the specifications provided by SEC, shall constitute an independent
     invention or creation of AST and SEC shall not make any claim as a joint
     developer or joint owner based upon SEC providing such specifications to
     AST.

4.3  Protections for Jointly Owned Rights.  Both parties shall from time to time
     ------------------------------------                                       
     discuss whether patent or copyright applications should be filed on, or
     other forms of intellectual property protection sought for, the jointly-
     owned Intellectual Property Rights, the party who will file and pay for
     such patent application and the country(ies) in which the same is to be
     filed. If one party believes that a particular type of intellectual
     property protection should be sought for a particular portion of the
     jointly owned Intellectual Property Rights (the "Initiating Party") but the
     parties can not agree, within a reasonable amount of time, as to whether
     that particular type of intellectual property protection should be sought
     for that particular jointly owned Intellectual Property Rights, then the
     Initiating Party shall be permitted to pursue such intellectual property
     protection for its sole ownership, if advance written notice of such filing
     is provided to the other party, and the other party shall cooperate (at the
     expense of the Initiating Party) in all ways reasonably requested by the
     Initiating Party provided that the Initiating Party shall bear the expense
     of obtaining such intellectual property protection, and the other party
     shall have a non-exclusive world-wide fully paid up license to such
     intellectual property protection.

4.4  Grant of License.  SEC hereby grants to AST and its Subsidiaries a non-
     ----------------                                                      
     exclusive, non-transferable, worldwide, perpetual and royalty-free license
     to use Technical Information supplied by SEC and under the Intellectual
     Property Rights therefor, subject to the terms of this Agreement, to: (a)
     develop, manufacture, have manufactured, use, and copy for the purpose of
     supplying Products to SEC; and (b) manufacture, use, copy, modify, sell,
     lease or otherwise dispose of any goods which are differentiated from the
     Products, subject to the terms and conditions of this Agreement.

4.5  Licenses to Subsidiaries.  Any license or other right granted to any
     ------------------------                                            
     Subsidiary hereunder shall immediately terminate at such time as such
     entity no longer satisfies the definition of Subsidiary as that term is
     defined in that certain General Terms Agreement between the parties of even
     date herewith.

4.6  Limitations on License.  Notwithstanding any other provision of this
     ----------------------                                              
     Agreement, for those patent rights licensed or sublicensed to AST from SEC
     under this Agreement, AST shall not have the right to grant licenses or
     sublicenses to any

                                       4
<PAGE>
 
     third parties, excepting for licenses or sublicenses to AST Subsidiaries
     to the extent permitted under this Agreement, and further excepting
     licenses which would otherwise be implied to purchasers of AST products
     for the use or resale of such products.  Notwithstanding any other
     provision of this Agreement, for those patent rights licensed or
     sublicensed to SEC from AST under this Agreement, SEC shall not have the
     right to grant licenses or sublicenses to any third parties, excepting for
     licenses or sublicenses to SEC Subsidiaries to the extent permitted under
     this Agreement, and further excepting licenses which would otherwise be
     implied to purchasers of AST products for the use or resale of such
     products.  Notwithstanding any other provision of this Agreement, any
     purported or attempted grant by AST or SEC of a license or sublicense
     contrary to this Agreement shall be of no force or effect.


Article 5.  Ordering

5.1  Forecasts.  SEC shall submit a written revolving six (6) month forecast to
     ---------                                                                 
     AST of anticipated purchases of the Products, and shall update the forecast
     monthly.  The last three (3) months of this forecast shall not be a
     commitment of either AST or SEC, but is necessary for the planning purposes
     of AST and SEC and for the convenience of each.  Unless otherwise agreed to
     by both SEC and AST, the immediately preceding three (3) months forecast
     shall be binding to the parties, provided that the forecast for the
     immediate first month shall be binding to the parties, month two (2), can
     be changed up to twenty percent (20%) and month three (3) forty percent
     (40%).

     purchase orders directly to AST for Product, and AST shall supply same to
     the Ordering Entity pursuant to the terms and conditions of this Agreement.
     Notwithstanding the foregoing, SEC and the Ordering Entity shall be
     severally and/or jointly liable for payment therefor.  This Agreement sets
     forth the terms and conditions which shall govern the transactions between
     the parties and Ordering Entities related to the Product.  No term or
     condition set forth in any purchase order submitted to AST by an Ordering
     Entity shall modify the terms and conditions herein.  Unless otherwise
     agreed to by SEC and AST, purchase orders pursuant to the said forecast,
     which shall be considered final and binding, shall be issued by SEC to AST
     with at least sixty (60) days lead time for delivery during the term of
     this Agreement.  AST agrees to bear any expedited shipping costs or other
     costs required to meet any previously committed AST delivery dates.  Any
     such purchase orders shall constitute separate contracts between AST and
     the ordering entity.

     acceptable open account credit limit for SEC's purchases of Products under
     this Agreement, and failing the mutual agreement as to such credit limit,
     prior to the shipment of Product by AST, SEC shall arrange an irrevocable
     letter of credit in favor of AST to be issued by a bank acceptable to AST
     and, if so requested by AST, to be confirmed by a Korean foreign exchange
     bank in such U.S. dollars and in such amount sufficient to cover the sales
     prices.


Article 8.  Infringement

     Unless otherwise agreed upon in writing between the parties
     hereto, AST is not responsible for any infringement with regard to patent
     rights, utility model rights, trademark, commercial design or copyrights in
     any country with respect to the Product; provided, however, that AST shall
     be responsible for the infringement of any intellectual property rights of
     third parties with respect to any processes employed by AST in the
     manufacture of the Product.


Article 9.  Subcontracting

     General Terms Agreement, SEC may require AST to transfer title and deliver
     to SEC any Product and semifinished products and materials, parts,
     drawings, and information subject to SEC's payment to AST for any incurred
     cost or expense therefrom, as AST has specifically produced or specifically
     acquired for the performance of such part of this Agreement.  Any and all
     licenses granted pursuant to this Agreement shall terminate upon such date
     as this Agreement terminates or expires regardless of the cause.


Article 11.  Warranty

11.1 General Warranty.  AST warrants to SEC that the Products will conform to
     ----------------                                                        
     the specifications provided by SEC and under normal use and maintenance,
     the Products will be free from defects in workmanship or materials for a
     period of 39 months from delivery.  AST shall deliver to SEC an additional
     number of parts equivalent to 1% of each product purchased to replace the
     anticipated quantity of defective products.  These parts will be delivered
     free of charge along with each shipment of Products purchased by SEC. The
     additional number of parts provided for in this Article 11.1 shall be the
     sole and exclusive remedy for breach of the warranty of this Article 11.1.

11.2 Excessive Failures.  AST further warrants that the Products shall be free
     ------------------                                                       
     from an Excessive Failure Rate (as hereinafter defined).  As used in this
     Section, an Excessive Failure Rate shall mean whenever during any ninety
     (90) day period more than thirty percent (30%) of a shipment lot of
     Products contain a defect in material and workmanship which defect is due
     to the same cause (an "Excessive Failure Rate").  If an Excessive Failure
     Rate is proven to exist, AST will, at no charge to SEC at AST's option, (a)
     repair or replace the affected Products in SEC and SEC's customer's
     inventory, or (b) at no charge to SEC, provide parts, special tools and
     documentation for SEC to repair or replace the affected Products in the
     affected shipment.

11.3 DOA Warranty.  Under Dead-On-Arrival (DOA) conditions, AST agrees to
     ------------                                                        
     supply repair parts and to provide personnel at SEC designated locations or
     at major AST customer sites to repair the DOA products which have major
     functional failures provided that the DOA rate exceeds five percent (5%)
     for lot sizes of 200 or more.  AST agrees to perform failure analysis for
     the defective units and to report corrective action to be taken to prevent
     reoccurrence to SEC engineers

                                       7
<PAGE>
 
     within fifteen (15) working days after notification by SEC. If repairs
     cannot be made within such fifteen (15) days period, SEC reserves the
     right to reject DOA products and to return them to AST for credit only.

11.4 Disclaimer.  NO OTHER WARRANTIES ARE GIVEN WHETHER EXPRESS OR IMPLIED,
     ----------                                                            
     INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
     PARTICULAR USE.


Article 12.  General Terms

     apply to this Agreement.


Article 13.  Priority

     In the event of a conflict or inconsistency between any term or
     condition of this Agreement and that of the General Terms Agreement, the
     terms and conditions of this Agreement shall supersede and control.  The
     terms and conditions of this Agreement shall be superseded and controlled
     by terms of any Product Plan signed by both parties hereto.

     same (the "Contemplated Transaction").  To exercise its right of first
     refusal, SEC shall advise AST of its intent to exercise its right of first
     refusal, in writing, at any time within the fourteen (14) business days
     following SEC's receipt of such notice (the "Exercise Period").  If SEC

     quotation to AST for the Products with all terms, conditions,
     specifications, quality requirements, prices, allocations, and other
     provisions at least as favorable as were offered to AST in the Contemplated
     Transaction.  If SEC notifies AST that it does not wish to exercise its
     right of first refusal or fails to respond to AST in writing within the
     Exercise Period (the "OEM Project Rejection") then AST

                                       2
<PAGE>
 
     shall be free to enter into the Contemplated Transaction on the same
     terms and conditions as offered to SEC; provided, however, that if the
     Contemplated Transaction is not entered into in writing between AST and a
     third party within six (6) months of the OEM Project Rejection then SEC's
     right of first refusal shall be revived with respect to the OEM product
     and technology related to the Contemplated Transaction and AST shall offer
     the OEM product and technology related to the Contemplated Transaction to
     SEC in accordance herewith prior to entering into any arrangement related
     to such OEM product or technology with any third party.


Article 3.  Technology Sharing

     In recognition of the advanced development nature of technology
     contemplated by the development of the Products, it is anticipated that AST
     and SEC will find it mutually beneficial to establish a close working
     relationship to exchange Technical Information to achieve the objectives of
     this Agreement.  Toward this end, the parties hereby agree to, within the
     confines of applicable law, provide each other with sufficient Technical
     Information to accomplish the purposes of each Product Plan adopted
     pursuant to this Agreement.  Any and all such Technical Information
     exchanged pursuant to this Agreement shall be treated as Confidential
     Information in accordance with the terms and conditions of that certain
     General Terms Agreement between the parties of even date herewith.


Article 4.  Proprietary Rights

4.1  Separately Owned Rights.  Any Technical Information which is developed or
     -----------------------                                                  
     conceived independently by each party hereunder and Intellectual Property
     Rights therefor shall remain the property of such developing party.

4.2  Jointly Owned Rights.  Any Technical Information which is developed or
     --------------------                                                  
     conceived jointly by both parties hereunder and Intellectual Property
     Rights therefor shall be the joint property of both parties.  Each party
     shall have a right to grant to its Subsidiaries the licenses under jointly
     owned Technical Information and Intellectual Property Rights therefor
     without obtaining a prior consent of and accounting for any compensation to
     the other party.  The party who wishes to grant to any third party any
     licenses under the jointly-owned Technical Information and any Intellectual
     Property Rights therefor shall obtain a prior written approval of the other
     party.  Notwithstanding any other provision hereof, the parties agree that
     any Technical

                                       3
<PAGE>
 
     Information or Intellectual Property Rights related to any
     development by SEC in connection with the development of the Product to
     satisfy the specifications provided by AST, shall constitute an independent
     invention or creation of SEC and AST shall not make any claim as a joint
     developer or joint owner based upon AST providing such specifications to
     SEC.

4.3  Protections for Jointly Owned Rights.  Both parties shall from time to time
     ------------------------------------                                       
     discuss whether patent or copyright applications should be filed on, or
     other forms of intellectual property protection sought for, the jointly-
     owned Intellectual Property Rights, the party who will file and pay for
     such patent application and the country(ies) in which the same is to be
     filed. If one party believes that a particular type of intellectual
     property protection should be sought for a particular portion of the
     jointly owned Intellectual Property Rights (the "Initiating Party") but the
     parties can not agree, within a reasonable amount of time, as to whether
     that particular type of intellectual property protection should be sought
     for that particular jointly owned Intellectual Property Rights, then the
     Initiating Party shall be permitted to pursue such intellectual property
     protection for its sole ownership, if advance written notice of such filing
     is provided to the other party, and the other party shall cooperate (at the
     expense of the Initiating Party) in all ways reasonably requested by the
     Initiating Party provided that the Initiating Party shall bear the expense
     of obtaining such intellectual property protection, and the other party
     shall have a non-exclusive world-wide fully paid up license to such
     intellectual property protection.

4.4  Grant of License.  AST hereby grants to SEC and its Subsidiaries a non-
     ----------------                                                      
     exclusive, non-transferable, worldwide, perpetual and royalty-free license
     to use Technical Information supplied by AST and under the Intellectual
     Property Rights therefor, subject to the terms of this Agreement, to: (a)
     develop, manufacture, have manufactured, use, and copy for the purpose of
     supplying Products to AST; and (b) manufacture, use, copy, modify, sell,
     lease or otherwise dispose of any goods which are differentiated from the
     Products, subject to the terms and conditions of this Agreement.

4.5  Licenses to Subsidiaries.  Any license or other right granted to any
     ------------------------                                            
     Subsidiary hereunder shall immediately terminate at such time as such
     entity no longer satisfies the definition of Subsidiary as that term is
     defined in that certain General Terms Agreement between the parties of even
     date herewith.

4.6  Limitations on License.  Notwithstanding any other provision of this
     ----------------------                                              
     Agreement, for those patent rights licensed or sublicensed to AST from SEC
     under this Agreement, AST shall

                                       4
<PAGE>
 
     not have the right to grant licenses or sublicenses to any third
     parties, excepting for licenses or sublicenses to AST Subsidiaries
     to the extent permitted under this Agreement, and further excepting
     licenses which would otherwise be implied to purchasers of AST
     products for the use or resale of such products.  Notwithstanding any other
     provision of this Agreement, for those patent rights licensed or
     sublicensed to SEC from AST under this Agreement, SEC shall not have the
     right to grant licenses or sublicenses to any third parties, excepting for
     licenses or sublicenses to SEC Subsidiaries to the extent permitted under
     this Agreement, and further excepting licenses which would otherwise be
     implied to purchasers of AST products for the use or resale of such
     products.  Notwithstanding any other provision of this Agreement, any
     purported or attempted grant by AST or SEC of a license or sublicense
     contrary to this Agreement shall be of no force or effect.


Article 5.  Ordering

5.1  Forecasts.  AST shall submit a written revolving six (6) month forecast to
     ---------                                                                 
     SEC of anticipated purchases of the Products, and shall update the forecast
     monthly.  The last three (3) months of this forecast shall not be a
     commitment of either AST or SEC, but is necessary for the planning purposes
     of AST and SEC and for the convenience of each.  Unless otherwise agreed to
     by both SEC and AST, the immediately preceding three (3) months forecast
     shall be binding to the parties, provided that the forecast for the
     immediate first month shall be binding to the parties, month two (2), can
     be changed up to twenty percent (20%) and month three (3) forty percent
     (40%).

5.2  Orders and Terms.  AST and its Subsidiaries ("Ordering Entity") may submit
     ----------------                                                          
     purchase orders directly to SEC for Product, and SEC shall supply same to
     the Ordering Entity pursuant to the terms and conditions of this Agreement.
     Notwithstanding the foregoing, AST and the Ordering Entity shall be
     severally and/or jointly liable for payment therefor.  This Agreement sets
     forth the terms and conditions which shall govern the transactions between
     the parties and Ordering Entities related to the Product.  No term or
     condition set forth in any purchase order submitted to SEC by an Ordering
     Entity shall modify the terms and conditions herein.  Unless otherwise
     agreed to by SEC and AST, purchase orders pursuant to the said forecast,
     which shall be considered final and binding, shall be issued by AST to SEC
     with at least sixty (60) days lead time for delivery during the term of
     this Agreement.  SEC agrees to bear any expedited shipping costs or other
     costs required to meet any previously committed SEC delivery dates.  Any
     such

                                       5
<PAGE>
 
     purchase orders shall constitute separate contracts between SEC and
     the Ordering Entity.


Article 6.  Minimum Purchase

6.1  Calendar Year 1996 Minimum.  At a minimum, AST guarantees to buy Product
     --------------------------                                              
     from SEC during calendar year 1996 in the aggregate price amount of Two
     Hundred Million Dollars US ($200,000,000), provided that the Products are
     approved in advance in writing by AST as meeting AST's market needs during
     calendar year 1996, and that the Products are provided with price,
     allocation, terms and conditions at least as favorable as AST is able to
     obtain from other suppliers or AST's own factories, and that SEC has
     adequate production capacity available to devote to satisfying AST's needs
     for such Products.  SEC agrees to use its best efforts to provide Products
     to AST in the amount of at least equal to the aggregate price amount stated
     above during calendar year 1996 which meet AST's market needs during
     calendar year 1996, and with price, allocation, terms and conditions which
     are at least as favorable as AST is able to obtain from other suppliers or
     AST's own factories.

6.2  Agreements on Subsequent Year Minimums.  The minimum purchase quantity of
     --------------------------------------                                   
     Products for all subsequent years during the term hereof shall be agreed
     upon in writing between both the parties by the end of each year, based on
     AST's annual sales growth rate by product group for the preceding calendar
     year, and SEC's demonstrated and anticipated capacity to provide Products
     to AST in the amount equal to such minimum purchase quantity which meet
     AST's market needs, and with price, allocation, terms and conditions which
     are at least as favorable as AST is able to obtain from other suppliers or
     AST's own factories.  Such an agreement shall become an integral part of
     this Agreement.

6.3  Default Amounts of Subsequent Year Minimums.  Should the parties fail to
     -------------------------------------------                             
     agree as to a minimum purchase quantity for any subsequent year, the fixed
     minimum purchase quantity for the immediately preceding year shall be
     applied to such subsequent year, provided that SEC has demonstrated during
     such preceding year its capacity to provide Products to AST in the amount
     equal to such minimum purchase quantity which meet AST's market needs, and
     with price, allocation, terms and conditions which are at least as
     favorable as AST is able to obtain from other suppliers or AST's own
     factories.

     Unless otherwise agreed upon in writing between the parties
     hereto, discussions shall be held between AST and SEC concerning an
     acceptable open account credit limit for AST's purchases of Products under
     this Agreement, and failing the mutual agreement as to such credit limit,
     prior to the shipment of Product by SEC, AST shall arrange an irrevocable
     letter of credit in favor of SEC to be issued by a bank acceptable to SEC
     and, if so requested by SEC, to be confirmed by a Korean foreign exchange
     bank in such U.S. dollars and in such amount sufficient to cover the sales
     prices.


Article 9.  Infringement

     Unless otherwise agreed upon in writing between the parties
     hereto, SEC is not responsible for any infringement with regard to patent
     rights, utility model rights, trademark, commercial design or copyrights in

Article 11.  Effect of Termination

     If this Agreement is terminated as provided in Article 3 of the
     General Terms Agreement, AST may require SEC to transfer title and deliver
     to AST any Product and semifinished products and materials, parts,
     drawings, and information subject to AST's payment to SEC for any incurred
     cost or expense therefrom, as SEC has specifically produced or specifically
     acquired for the performance of such part of this Agreement.  Any and all

     as this Agreement terminates or expires regardless of the cause.


Article 12.  Warranty

12.1 General Warranty.  SEC warrants to AST that the Products will conform to
     ----------------                                                        
     the specifications provided by AST and under normal use and maintenance,
     the Products will be free from defects in workmanship or materials for a
     period of 39 months from delivery.  SEC shall deliver to AST an additional
     number of parts equivalent to 1% of each product purchased to replace the
     anticipated quantity of defective products.  These parts will be delivered
     free of charge along with each shipment of Products purchased by AST.  The
     additional number of parts provided for in this Article 12.1 shall be the
     sole and exclusive remedy for breach of the warranty of this Article 12.1.

12.2 Excessive Failures.  SEC further warrants that the Products shall be free
     ------------------                                                       
     from an Excessive Failure Rate (as hereinafter defined).  As used in this
     Section, an Excessive Failure Rate shall mean whenever during any ninety
     (90) day period more than thirty percent (30%) of a shipment lot of
     Products contain a defect in material and workmanship which defect is due
     to the same cause (an "Excessive Failure Rate").  If an Excessive Failure
     Rate is proven to exist, SEC will, at no charge to AST at SEC's option, (a)
     repair or replace the affected Products in AST and AST's customer's
     inventory, or (b) at no charge to AST, provide parts, special tools and
     documentation for AST to repair or replace the affected Products in the
     affected shipment.

12.3 DOA Warranty.  Under Dead-On-Arrival (DOA) conditions, SEC agrees to
     ------------                                                        
     supply repair parts and to provide personnel at AST designated locations or
     at major AST customer sites to repair the DOA products which have major
     functional failures provided that the DOA rate exceeds five percent (5%)
     for lot sizes of 200 or more.  SEC agrees to perform failure analysis for
     the defective units and to report corrective action to be taken to prevent
     reoccurrence to AST engineers within fifteen (15) working days after
     notification by AST.  If repairs cannot be made within such fifteen (15)
     days

                                       8
<PAGE>
 
     period, AST reserves the right to reject DOA products and to return
     them to SEC for credit only.

12.4 Disclaimer.  NO OTHER WARRANTIES ARE GIVEN WHETHER EXPRESS OR IMPLIED,
     ----------                                                            
     INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
     PARTICULAR USE.

     conceived independently by each party hereunder and Intellectual Property
     Rights therefor shall remain the property of such developing party.

                                       5
<PAGE>
 
6.2  Jointly Owned Rights.  Any Technical Information which is developed or
     --------------------                                                  
     conceived jointly by both parties hereunder and Intellectual Property
     Rights therefor shall be the joint property of both parties.  Each party
     shall have a right to grant to its Subsidiaries the licenses under jointly
     owned Technical Information and Intellectual Property Rights therefor
     without obtaining a prior consent of and accounting for any compensation to
     the other party.  The party who wishes to grant to third party any licenses
     under the jointly-owned Technical Information and any Intellectual Property
     Rights therefor shall obtain a prior written approval of the other party.

6.3  Protections for Jointly Owned Rights.  Both parties shall from time to time
     ------------------------------------                                       
     discuss whether patent or copyright applications should be filed on, or
     other intellectual property protections obtained for, the jointly-owned
     Intellectual Property Rights, the party who will file and pay for such
     application and the country(ies) in which the same is to be filed. If one
     party believes that a particular type of intellectual property protection
     should be sought for a particular portion of the jointly owned Intellectual
     Property Rights (the "Initiating Party") but the parties can not agree,
     within a reasonable amount of time, as to whether that particular type of
     intellectual property protection should be sought for that particular
     jointly owned Intellectual Property Rights, then the Initiating Party shall
     be permitted to pursue such intellectual property protection for its sole
     ownership, if advance written notice of such filing is provided to the
     other party, and the other party shall cooperate (at the expense of the
     Initiating Party) in all ways reasonably requested by the Initiating Party
     provided that the Initiating Party shall bear the expense of obtaining such
     intellectual property protection, and the other party shall have a non-
     exclusive world-wide fully paid up license to such intellectual property
     protection.

6.4  Disclosure Of Inventions.  Each party shall promptly disclose to the other
     ------------------------                                                  
     in writing on a confidential basis all Technical Information which is
     jointly invented, authored or otherwise brought into being pursuant to a
     Development Plan hereunder (including derivatives or analogues of
     preexisting technical information) and/or commercially useful research
     products or processes jointly invented, authored or otherwise brought into
     being pursuant to a Development Plan, including, but not limited to,
     materials, whether patentable or unpatentable, or whether trade secrets or
     whether susceptible to copyright or other forms of protection.

6.5  Proprietary Protection Cooperation.  Each party will cooperate with the
     ----------------------------------                                     
     other in taking such actions as such party reasonably requests for the
     purposes of filing and obtaining copyright registrations, patents and
     other

                                       6
<PAGE>
 
     suitable forms of protection of the Technical Information which is jointly
     invented, authored or otherwise brought into being hereunder and securing
     title to such forms of protection in accordance with Article 6.3 of this
     Agreement and enforcing any rights therein.  Such efforts by each party
     will be at the expense of the requesting party.  In addition, without
     limiting the foregoing, each party agrees to cooperate with the other party
     to whatever extent is necessary to procure patent protection of any rights
     to any Technical Information which is jointly invented, authored or
     otherwise brought into being hereunder including agreeing to execute any
     and all documents to give each other the full benefit of the licenses
     granted herein.

     --------------------                                                       
     interest of any Technical Information which is jointly invented, authored
     or otherwise brought into being hereunder may exist or arise in one party
     or any employee or agent thereof, each party agrees that it shall assign
     any and all such individual ownership interests as necessary or desirable
     to achieve joint ownership of such Technical Information which is jointly
     invented, authored or otherwise brought into being hereunder.

6.7  Obligation To Obtain Rights From Researchers.  The parties hereby agree
     --------------------------------------------

     and all employees, agents, any other researchers who are engaged in the
     research projects undertaken pursuant to this Agreement (referred to as
     "Project Personnel") to assign their right, title and interest in and to
     the Technical Information which is jointly invented, authored or otherwise
     brought into being by both SEC and AST under a Development Plan of this
     Agreement, by any such person during the course of the performance of this
     Agreement as are necessary to give effect to the provisions of this
     Agreement respecting ownership of the Intellectual Property Rights
     hereunder.  In addition, each party will obtain the agreement of all
     Project Personnel to cooperate fully with either SEC or, as the case may
     be, AST in pursuing legal protection for any such improvements thereto,
     including, without limitation, providing assistance in filing and
     presenting any patent applications or copyrights on such inventions or
     improvements and, upon reasonable request, furnishing samples of any
     Technical Information which is jointly  invented, authored or brought into
     being by both SEC and AST under a Development Plan hereunder.  Both parties
     represent and warrant that they are legally entitled by written agreement
     to exclusive ownership of any invention of any employee or agent who will
     participate in the collaborative effort under this Agreement, and that each
     party has the right to and will assign such ownership interests as provided
     in this Agreement free of any third-party claim.  SEC and AST agree that
     the use of the current patent pre-

                                       7
<PAGE>
 
     assignment form agreements and other terms of employment and retainer of
     consultants used by SEC and AST are adequate to satisfy the obligations
     of this Article 6.7.

     ----------------                                                        
     interim and final results of their cooperative research hereunder.  Summary
     reports shall be prepared and exchanged between the parties at least as
     often as is specified in the Development Plan.  Such reports shall include,
     in part, a discussion and analysis of the opinion of each party's principal
     investigator of the then current status of and potential for commercial
     development and marketability of any Technical Information which is jointly
     invented, authored or otherwise bought into being hereunder.  The complete
     documentation of each party shall be made available to the other upon
     request.  The parties shall jointly prepare a comprehensive final report
     within thirty (30) days following termination of each Development Plan.
     All reports and documentation under this Section shall constitute
     Confidential Information and as such shall be afforded all protections set
     forth in the General Terms Agreement.

6.9  Access To Research Results.  So long as the rights of either party in any
     ---------------------------                                              
     Technical Information which is jointly invented, authored or otherwise
     brought into being hereunder continue hereunder following termination of
     this Agreement, such party and its authorized representatives shall have
     access to the information and results of research reflected therein at
     reasonable times during normal business hours.

      ---------------------                                                     
     their obligations under this Agreement shall conform in all material
     respects to all applicable laws and regulations of the U.S. and foreign
     governments (and political subdivisions thereof), including but not limited
     to, the US export control laws and regulations.

6.11  Publication of Research.  Neither party shall publish the results of any
      -----------------------                                                 
     research related in any way to any Technical Information which is jointly
     invented, authored or otherwise brought into being hereunder without the

Article 10.  Arbitration

10.1 Negotiation and Arbitration.  All disputes arising during performance under
     ---------------------------                                                
     the AGREEMENT shall be settled through friendly negotiation between the
     parties, including providing written notice of the dispute to the other
     party in advance of submitting any dispute to arbitration or making any
     filing with any judicial, administrative or regulatory authority concerning
     the dispute.  The parties agree, when time and circumstances reasonably
     permit, that no arbitration, judicial, administrative or regulatory action
     concerning a dispute between the parties will be started until after the
     senior executive of each company has attempted to speak (in person, by
     telephone or by videophone) to the other concerning the dispute and
     attempted to resolve the dispute.  In case no settlement can be reached,
     the dispute shall be submitted to arbitration if both parties determine
     that the subject matter of the dispute is such that arbitration will be an
     efficient, effective and timely method of resolving the dispute.

10.2 Arbitration Procedures.  If the dispute is submitted to arbitration, the
     ----------------------                                                  
     dispute shall be finally settled by an arbitration tribunal which shall be
     convened and conducted in accordance with the applicable rules and
     procedure of arbitration of the International Chamber of Commerce adopted
     in 1988.  The arbitration proceeding shall be held before three (3)
     arbitrators in the headquarters city of the party not initiating the claim.
     Two (2) of the arbitrators shall first be appointed by the parties, one (1)
     by AST and one (1) by SEC.  The arbitrators so appointed shall appoint a
     third arbitrator who shall be neither an ROK nor a U.S. national, and shall
     act as the chairman of the arbitral tribunal.  If the arbitrators appointed
     by the parties fail to appoint a third arbitrator within sixty (60) days
     after they have been appointed, the third arbitrator may be appointed by
     the arbitration body before which the arbitration is being held.  In such
     event, the third arbitrator shall be neither an ROK nor a U.S. national.
     The arbitration proceedings shall be conducted in English, and the law
     applied shall be the same as the governing law selected in Article 9 of
     this Agreement.  The results of such arbitration shall be conclusive and
     binding upon the parties, and shall be enforceable in any court having
     jurisdiction over the parties against whom the award was rendered.

Article 11.  Severability

     Should any clause, sentence, or paragraph of the AGREEMENT judicially be
     declared to be invalid, unenforceable, or void, such decision shall not
     have the effect of invalidating or voiding the remainder of the AGREEMENT

                                       8

     unless the economic equity of the parties is materially affected thereby.

Article 12.  Force Majeure

     any other actions of Government authorities, riots, civil commotion,
     warlike conditions, strikes, lockout, shortage or control of power supply,
     plague or other epidemics, fire, flood, tidal waves, typhoon, hurricane,
     cyclone, earthquake, lightning, explosion, or any other causes beyond the
     reasonable control of either party or Force Majeure, neither party shall be
     liable for any default in performance of the AGREEMENT arising therefrom.

Article 13.  LIMITATION OF LIABILITY

     IN NO EVENT SHALL EITHER PARTY BE LIABLE TO THE OTHER PARTY FOR ANY
     SPECIAL, CONSEQUENTIAL, INCIDENTAL OR INDIRECT DAMAGE OF ANY KIND,
     (INCLUDING WITHOUT LIMITATION LOSS OF PROFIT OR DATA) WHETHER OR NOT
     ADVISED OF THE POSSIBILITY OF SUCH LOSS.

Article 14.  Entire Agreement

     The AGREEMENT sets forth the entire agreement and understanding between the
     parties as to the subject matter of the AGREEMENT and merges all prior
     discussions between them, and neither of the parties shall be bound by any
     modification of the AGREEMENT, other than as expressly provided in the

     writing and signed by a duly authorized representative of the party to be

     transactions contemplated by the AGREEMENT and carry out the purpose
     and intent of the AGREEMENT.

Article 17.  Equitable Relief

     The parties acknowledge and agree that any unauthorized use, transfer or
     copying of the Confidential Information will cause irreparable injury to
     the Disclosing Party by substantially diminishing the value of the
     Disclosing Party's trade secrets and other proprietary rights contained in
     the Confidential Information.  Therefore, if the Receiving Party (including
     its employees and consultants) attempts to use, transfer, copy, license,
     assign or otherwise convey the Confidential Information in any manner
     contrary to the terms of the AGREEMENT, the Disclosing Party shall, in
     addition to any other remedies available to it, have the right to enjoin,
     preliminary and permanently, the Receiving Party from any such act, and the
     Receiving Party hereby acknowledges that other remedies are inadequate and
     consents to such injunction, provided that the court being requested to
     provide such remedy would otherwise find adequate grounds for such remedy.

     Any action arising out of or related to the AGREEMENT or the transaction
     herein described, whether at law or in equity, not otherwise subject to
     International Arbitration under Article 10 hereof including, without
     limitation, the enforcement of any award, the seeking of injunctive relief
     to prevent or restrain infringement of valid intellectual property rights,
     may be instituted in and litigated in the courts of the Republic of Korea
     or the Courts of the United States of America.  In accordance herewith, the
     parties hereto submit to the jurisdiction of the courts of the Republic of
     Korea and the courts of the United States of America.

     ("Products") and are used in connection with foreign or domestic government
     contracting or subcontracting, including, without limitation, either
     party's performance of any government contracts or subcontracts (the
     "Government Contracting Party"), then the Government Contracting Party
     shall ensure that:  (l) the Products shall not constitute deliverables
     under any government contracts or subcontracts, and (2) no government
     entity shall acquire, under the terms of any government contracts or
     subcontracts, or any applicable government contracting laws, rules or
     regulations, any intellectual property rights of any nature in the
     Products, including rights under any copyrights, patents, trade secrets, or

                                       10
<PAGE>
 
     other proprietary rights attendant thereto.  However, either party may
     supply Products to government agencies and transfer the usual rights to use
     the products or prepare archival copies of software, in accordance with the

     excise taxes), customs duties and import/export fees of any kind
     (including, without limitation, any fees for permits or licenses related to
     import/export compliance) paid or now or hereafter payable, however
     designated, levied or based on amounts payable to the selling party
     hereunder, on the purchasing party's acquisition, use or possession of the
     Products under the AGREEMENT or upon the presence of the Products at the
     designated site, but exclusive of federal, state and local taxes based on
     the selling party's net income.  The purchasing party shall not deduct or
     withhold from payments to selling party any amounts paid or payable to
     third parties for taxes, customs duties or import/export fees, however
     designated.

Article 22.  Due Execution

                   ------------------------------------------------ 

          (a)  At any time and from time to time until 270 days after the
Closing, the Purchaser may purchase in the open market at any available price up
to that aggregate number of additional shares of Voting Stock which, if they had
been acquired by the Purchaser in the open market on the date of the Closing,

in connection with each such issuance the Purchaser and/or its Affiliates shall
have the right, but not the obligation, to purchase in the open market at any
available price, up to such number of additional shares of Voting Stock as may
then be necessary solely as a result of such issuance to restore the Purchaser
Interest to the same percentage of the Total Voting Power as existed immediately
prior to such increase in the number of outstanding shares of Voting Stock,
provided that any shares of Voting Stock acquired by the Purchaser pursuant to
Section 2.1.4(a) shall be deemed to have been acquired at the Closing for
----------------                                                         
purposes of determining the Purchaser Interest immediately prior to such
increase in the number of outstanding shares of Voting Stock.  The purchase
right set forth in this Section 2.1.4(b)  shall be exercisable at any time and
                        -----------------

           2.1.6. Third-Party Offers. From and after the Closing of the purchase
                  ------------------  
and sale of the Second Issuance Shares until such time as the Purchaser Interest
has been less than 30% for a period of at least twenty-five (25) consecutive
days, in the event any Third Party shall make an offer to acquire a 20% or
greater interest in Equity Securities, the Purchaser and/or its Affiliates shall
be permitted to make a competing offer, and acquire Equity Securities pursuant
thereto, subject to and in accordance with the following:

                                       3
<PAGE>
 
          (a)  If (i) the Third Party offer is approved or recommended by a
majority vote of the Directors not designated by the Purchaser pursuant to this
Agreement, or (ii) there shall be in effect no Rights Agreement or the Board
shall have amended or rescinded the Rights Agreement to exclude the Third Party
from the definition of "Acquiring Person" or permit the Third Party offer to
proceed without resulting in a Distribution Date or a Triggering Event or the
Rights becoming exercisable or (iii) a court of competent jurisdiction shall
have entered an order invalidating the Rights Agreement with respect to the
Third Party offer or ordering that the Rights be rescinded or the Rights
Agreement be so amended, then the Purchaser shall have the right to make a
competing offer and to acquire Equity Securities pursuant to such competing
offer, provided that (1) the competing offer complies with Section 2.1.6(b), (2)
                                                           ----------------     
the competing offer is made prior to the withdrawal or termination of the Third
Party offer, and (3) if the Third Party offer is withdrawn or terminated before
the Purchaser acquires Equity Securities pursuant to the competing offer, the
Board determines in good faith that such Third Party offer was withdrawn or
terminated primarily as a result of the Purchaser's competing offer having
superior terms  to or a substantially greater likelihood of success than such
Third Party offer.  The Company shall not enter into any agreement with the
Third Party offeror or take any action required as a condition of the Third
Party offer unless and until the Purchaser shall have been notified in writing
by the Company of the right of the Purchaser and/or its Affiliates to submit a
competing offer hereunder, and the Purchaser and/or its Affiliates shall have
been afforded not less than ten (10) Business Days following receipt of such
notice in which to submit its competing offer for consideration by the Board.

          (b)  Any competing offer by the Purchaser pursuant to this Section
                                                                     -------
2.1.6 shall be, as nearly as possible, for an identical amount of securities and
-----                                                                           
at a price per share no lower than and on terms no less favorable than are
offered by the Third Party, provided that any such offer may be subject to any
governmental or regulatory approvals required by Korean law.  In the event the
consideration offered in any Third Party offer shall consist of securities or
property other than cash, the competing offer by the Purchaser may in the
Purchaser's discretion be for cash in an amount per share not less than the fair
market value of the consideration offered by the Third Party.

      2.1.7. Maximum Purchaser Ownership. Notwithstanding anything in this
             ---------------------------
Section 2.1 to the contrary, from the date of this Agreement until the
expiration of the Standstill Period, neither the Purchaser nor any of its
Affiliates may (directly or indirectly) acquire, or offer to acquire, Beneficial
Ownership of any Voting Stock if, after such acquisition, the Purchaser Interest
(calculated as though Beneficial Ownership of Voting Stock includes shares of
Voting Stock that the Purchaser has the right to acquire (other than pursuant to
this Agreement) as described in subsection (d)(1)(i) of Rule 13d-3 under the
Exchange Act without regard to the 60-day limit set forth therein) would exceed
49.9%, unless such acquisition or offer (together with related transactions) is
(a) made pursuant to Section 2.1.6, or (b) has been approved by a majority of
                     -------------  
the Directors not designated by the Purchaser pursuant to this Agreement and
would result in the Purchaser and/or its Affiliates owning 100% of the Voting
Stock.

      2.2. Pro-Rata Purchase Right. From and after the Closing of the purchase
and sale of the Second Issuance Shares until such time as the Purchaser Interest
has been less than 30% for a period of at least twenty-five (25) consecutive
days, the Company shall give the Purchaser at least

                                       4
<PAGE>
 
twenty-five (25) (and, when possible, at least ninety-five (95)) days' prior
written notice of the issuance by the Company of any New Securities as a result
of which the Purchaser Interest would be reduced, either immediately upon
issuance of such New Securities, or upon subsequent exercise or conversion
thereof. Such notice shall set forth (a) the approximate number and type of
securities proposed to be issued and sold to persons other than the Purchaser
and/or its Affiliates and the material terms of such securities, (b) the
proposed price or range of prices at which such securities are proposed to be
sold and the terms of payment, (c) the number of such securities offered to the
Purchaser and/or its Affiliates in compliance with this Section 2.2, and (d)
                                                        -----------         
the proposed date of issuance of such securities.  The Purchaser may, by notice
given to the Company within fifteen (15) days after such Company notice and so
long as permitted by applicable laws and regulations, elect to purchase up to
its pro rata share of such New Securities.  Such pro rata share shall be a
percentage of the proposed issuance equal to the Purchaser Interest (calculated
as though Beneficial Ownership of Voting Stock includes shares of Voting Stock
that the Purchaser has the right to acquire (other than pursuant to this
Agreement) as described in subsection (d)(1)(i) of Rule 13d-3 under the Exchange
Act without regard to the 60-day limit set forth therein) immediately prior to
such issuance.  The Purchaser's pro-rata purchase shall be on the same terms as
the balance of such issuance, provided that if the sale price at which the
Company proposes to issue, deliver or sell any New Securities is to be paid with
consideration other than cash, then the purchase price at which the Purchaser
may acquire such New Securities shall be equal in value (as determined in good
faith by the Board) but payable entirely in cash.  The closing of the
Purchaser's purchase of New Securities pursuant to this Section 2.2 shall occur
                                                        -----------            
simultaneously with the closing of the balance of such issuance, provided that
if as of the date of the closing of the balance of such issuance the Purchaser
has not received all approvals of Governmental Authorities required in
connection with the Purchaser's participation in such issuance, then (i) the
Purchaser shall not be required to effect its purchase under this Section 2.2
                                                                  -----------
until such approvals have been received, and (ii) the Company may terminate the
Purchaser's right to participate in such issuance if the Purchaser has not
effected its purchase within 120 days of receipt from the Company of written
notice of the New Issuance.  If the Purchaser elects such deferral, the Company
may close the portion of the issuance other than the Purchaser's portion prior
to the closing of the issuance of the Purchaser's portion.  If the terms of the
proposed issuance are materially changed from those stated in the Company's
notice to the Purchaser of such issuance, then the proposed issuance shall be
treated as a new issuance, subject again to this Section 2.2, and any election
                                                 -----------                  
to purchase made prior to such change may, at the sole discretion of the
Purchaser, be withdrawn.

     The Purchaser's pro-rata purchase right pursuant to this Section 2.2 shall
                                                              -----------      
not apply, however, to:

               (i) any issuance pursuant to (a) any stock option or purchase
right or plan exclusively for one or more employees and/or directors of the
Company or any of its subsidiaries or (b) warrants issued to Directors prior to
the date hereof;;

               (ii) any issuance in consideration of any part of the acquisition
by the Company or any subsidiary of any stock, assets or business;

               (iii)  any issuance upon conversion of the LYONs;

                                       5
<PAGE>
 
               (iv) any issuance pursuant to the exercise or conversion of any
New Security issued after the date hereof in a transaction in which the
Purchaser was entitled to participate pursuant to this Section 2.2; or
                                                       ----------- 

               (v) any issuance in payment of any portion of the Tandy Note.

      2.3. Notice and Subscription Procedures. In addition to the notice
required under Section 2.2, the Company shall notify the Purchaser of, and
               -----------
provide the Purchaser with an accurate and complete description of, any
event that will cause the rights of the Purchaser and/or its Affiliates to
acquire or offer to acquire Equity Securities under Section 2.1 (other than
                                                    -----------
Section 2.1.2 or 2.1.5) to become exercisable. The Company shall deliver
-------------    -----
such notice to the Purchaser as promptly as practicable after becoming
aware of such event, and when possible at least ninety-five (95) days prior
to the anticipated date of such event, provided that notice of issuances of
a kind described in subsection (i), (iii), or (iv) of Section 2.2, need
                                                      -----------
only be delivered within 15 days following the end of each fiscal quarter
of the Company.

      2.4. Acquisitions After Standstill Period. After the Standstill Period,
this Agreement shall not restrict the acquisition or offer to acquire any Equity
Securities or interest therein by the Purchaser and/or its Affiliates; provided,
however, that the Purchaser shall not acquire or offer to acquire any Equity
Securities if, as the result of or after giving effect to such acquisition, the
Purchaser Interest (calculated as though Beneficial Ownership of Voting Stock
includes shares of Voting Stock that the Purchaser has the right to acquire
(other than pursuant to this Agreement) as described in subsection (d)(1)(i) of
Rule 13d-3 under the Exchange Act without regard to the 60-day limit set forth
therein) would exceed 66.67%, except pursuant to a cash tender offer for all
Equity Securities not owned by the Purchaser and/or its Affiliates.

                                   ARTICLE 3.
                               TRANSFER OF SHARES

     The Purchaser and its Affiliates shall not sell or otherwise transfer
(except to an Affiliate of the Purchaser which shall agree to be bound by this
Agreement) any Equity Securities Beneficially Owned by such persons or any
interest therein for a period of five (5) years from the Closing of the purchase
and sale of the First Issuance Shares, except as follows:

      3.1. Pro-Rata Transactions. From and after the third anniversary of the
Closing of the purchase and sale of the First Issuance Shares, the Purchaser
and/or any of its Affiliates may sell any or all Equity Securities Beneficially
Owned by such persons in any transaction or transactions in which each other
holder of Equity Securities has the opportunity to sell the same percentage of
such stockholder's Equity Securities as the Purchaser and such Affiliates, at a
price and on terms no less favorable than those applicable to the sale by the
Purchaser and/or its Affiliates.

      3.2. Public Offerings and Market Transactions. From and after the third
anniversary of the Closing of the purchase and sale of the First Issuance Shares
(or, in the case of Common Stock acquired from the Company pursuant to Section
3.3 of the Letter of Credit Agreement, at any time and from time to time), the
Purchaser and/or any of its Affiliates may sell any or all

                                       6
<PAGE>
 
Equity Securities Beneficially Owned by such persons in one or more registered
public offerings or in market transactions if the Purchaser and/or its selling
Affiliates invoke and follow or require participating underwriters or brokers to
invoke and follow appropriate and reasonable procedures (subject to the
Company's prior approval, which shall not be unreasonably withheld) designed to
prevent the sale of such Equity Securities to any person or "group" (within the
meaning of Section 13(d)(3) of the Exchange Act) that would, after giving effect
to its acquisition of such Equity Securities, Beneficially Own or have the right
to acquire more than ten percent (10%) of the Total Voting Power.

      3.3. Directors' Approval. The Purchaser and/or any of its Affiliates may
sell any or all Equity Securities Beneficially Owned by such persons in any
transaction or transactions approved by a majority of the Directors other than
Directors designated by the Purchaser pursuant to this Agreement.

     In the event the Purchaser shall sell or otherwise transfer any Equity
Securities or any interest therein to an Affiliate, then so long as any such
Equity Securities are Beneficially Owned by such Affiliate, the provisions of
this Article shall apply to any sale or transfer of the capital stock or other
equity interests of such Affiliate such that it would cease to be an Affiliate
of the Purchaser.

                                   ARTICLE 4.

      4.1.   Purchaser Designees.


           4.1.1. Full Investment. At all times and from time to time after
                  ---------------
acquisition by the Purchaser of the Original Investment Shares, subject to
Section 4.1.2, the Purchaser shall have the right to designate that number of
-------------
Directors as will result in the total number of Directors designated by the
Purchaser being one fewer than a majority of the total number of Directors then
authorized under the Company's Certificate of Incorporation. Subject to Section
                                                                        -------
4.2, this Section 4.1.1 shall not limit the right of the Purchaser to nominate
---               -----
and seek the election of additional Directors after the Standstill Period.

           4.1.2. Partial Investment. If (a) the Purchaser acquires the First
                  ------------------
Issuance Shares, but does not also acquire all other Original Investment Shares,
or (b) the Purchaser acquires the Original Investment Shares but the Purchaser
Interest shall thereafter at any time have been less than thirty percent (30%)
for a period of at least twenty-five (25) consecutive days, then the Purchaser
shall from time to time have the right to designate that number of Directors as
will result in the total number of Directors designated by the Purchaser being
equal to the product (rounded to the nearest whole number) of (i) the total
number of Directors then authorized under the Company's Certificate of
Incorporation, and (ii) the Purchaser Interest at that time.

           4.1.3. Purchaser Directors. Any Director designated by the Purchaser
                  -------------------  
shall not serve as a Director if such person shall be prohibited from serving as
a Director under applicable law, including antitrust law.

                                       7

      4.2. Independent Directors. At all times until such time as the Purchaser
Interest shall have been less than 30% for a period of at least twenty-five (25)
consecutive days or more than 90% for a period of at least twenty-five (25)
consecutive days, the Board shall include at least three Independent Directors.

      4.3.  Additional Agreements.

           4.3.1. By the Company. The Company shall from time to time increase
                  --------------
the number of Directors constituting the Board and/or obtain resignations from
Directors (other than designees of the Purchaser and Independent Directors
required by Section 4.2) as may be required to ensure that there will at all
            ----------- 
times be sufficient Board seats available to accommodate the full number of
Directors that the Purchaser is then entitled to designate pursuant to Section
                                                                       -------  
4.1. The Company shall promptly and at all times use its best efforts, and take
---
all such actions as may be appropriate or necessary for the election to the
Board of the Purchaser designees selected pursuant to Section 4.1 and the
                                                      -----------
Independent Directors required pursuant to Section 4.2. Such actions shall
                                           -----------  
include, without limitation, the solicitation of proxies for the election of
such persons at each regular or special meeting of stockholders of the Company

                  ------------     --- 
such Independent Directors as are required by Section 4.2 and otherwise as the
                                              ----------- 
Purchaser and its Affiliates may determine in their discretion. If at any time
prior to the end of the Standstill Period the number of Directors that the
Purchaser is entitled to designate pursuant to Section 4.1 is fewer than the
                                               ----------- 
number of Purchaser designees then serving on the Board, the Purchaser shall
promptly obtain resignations from such of its designees (chosen by the
Purchaser) as may be required to cause the number of Purchaser designees serving
on the Board to be equal to the number of Directors that the Purchaser is then
entitled to designate.

           4.3.3. By the Purchaser and the Company. Names of all Director
                  --------------------------------
nominees designated by the Purchaser or by those Directors of the Company not
designated by the Purchaser shall be furnished to the Purchaser and the Company
(a) in the case of election of Directors at an annual meeting or otherwise

Director designees to serve on each committee of the Board (except as otherwise
provided in Section 12 of Article III of the Amended Bylaws with respect to the
Management Committee). The Purchaser shall be entitled to select any of the
Directors as alternates for each of its Director designees serving on committees
of the Board, which alternates shall be the designees of the Board for

<PAGE>
 
purposes of the Amended Bylaws and Section 141(b) of the Delaware General
Corporation Law and may replace any of the Purchaser's Director designees
serving on any committee who are absent or disqualified at any meeting of the
committee. With respect to the audit committee, any Purchaser Director designee
shall, as a condition to membership thereon, meet all requirements imposed by
the rules of any national securities exchange, or the Nasdaq National Market, on
which the Company's Shares may then be listed or quoted. With respect to the
compensation committee, any Purchaser Director designee shall, as a condition to
membership thereon, qualify as "disinterested" within the meaning of Rule 16b-3
under the Exchange Act or any similar rule then in effect.

      4.5. Vacancies. If any Director or Director nominee designated by the

                      -----------
removed from, or for any other reason be unable to serve on the Board or any
committee thereof, the vacancy resulting therefrom shall be filled in accordance
with the Company's Certificate of Incorporation and Bylaws by another person

serve on, resign or be removed from, or for any other reason be unable to serve
on the Board or any committee thereof during the Standstill Period, the vacancy
resulting therefrom shall be filled in accordance with the Company's Certificate
of Incorporation and Bylaws by a person designated by a majority of the
Directors of the Company other than those designated by the Purchaser. This
Section 4.5 shall not operate to allow the Purchaser or the Directors other than
-----------
those designated by the Purchaser to designate more Directors or committee
members than it or they would be entitled to designate hereunder but for this
Section 4.5.
-----------

      4.6. Directors' Indemnification and Insurance. As long as any designees of
the Purchaser serve on the Board, (a) the Amended and Restated Certificate of
Incorporation and Bylaws of the Company shall not be amended to contain
provisions less favorable with respect to indemnification and limitation of
liability of Directors than are set forth in the Amended and Restated
Certificate and Amended Bylaws as of the date of this Agreement, or in any other
manner that would affect adversely the rights thereunder of designees of the
Purchaser serving on the Board, unless such amendment, repeal or modification
shall be required by law or the fiduciary obligations of the Board, as
determined in good faith by the Board based on the written advice of outside
counsel, and (b) such designees shall be covered by any directors' and officers'
liability insurance maintained from time to time on the same terms and subject
to the same conditions as the other members of the Board, and (c) such designees
shall be entitled to the benefit of any indemnification agreements entered into
by the Company with any of its Directors; provided, that nothing in this
Agreement shall obligate the Company to maintain any such insurance or to enter
into any such indemnification agreements.

      4.7. Directors' Compensation. The Directors designated by the Purchaser,
if any, who are not officers or employees of the Purchaser and its Affiliates
shall have the right to receive all fees paid and options and other awards
granted and expenses reimbursed to non-employee Directors generally, provided
that all such fees and awards allocable to Directors who are not officers or
employees of the Purchaser and its Affiliates shall not be paid or awarded or
transferred to the Purchaser. Directors designated by the Purchaser who are
officers or employees of the Purchaser or its Affiliates shall have the right to
receive only such fees, options

                                       9

and awards allocable to Directors designated by the Purchaser shall, in the

                             RESULTS OF OPERATIONS

     Following the acquisition by the Purchaser of the Original Investment
Shares, and provided that the Purchaser Interest shall not have been less than
thirty percent (30%) for a period of at least twenty-five (25) consecutive days,
if (a) the consolidated revenues or gross profits of the Company and its
subsidiaries for the fiscal year ended July 1996 shall be less than $2.6 billion
or $430 million, respectively, (b) the consolidated revenues or gross profits of
the Company and its subsidiaries for the fiscal year ended July 1997 shall be
less than the greater of (i) $2.75 billion or $450 million, respectively, or
(ii) 85% of the amounts therefor set forth in the 1997 operating plan of the
Company approved by the Board; or (c) the consolidated net income after taxes of
the Company and its subsidiaries for either of such fiscal years shall be less
than 1% of net revenues, then the Management Committee of the Board shall
review the desirability of changes in the management of the Company and take
such action, if any, as may be determined to be advisable including without
limitation the reassignment, changes in the responsibilities, removal,
termination or replacement of any members of  management.  For purposes of the
foregoing, the "management" of the Company shall refer to all persons who
presently have the title of "Vice President" or higher, whether or not any such
person is an officer of the corporation, and all such persons who may perform
the functions presently performed by any of the foregoing, without regard to
title, but shall not include the Chief Executive Officer.  The Management
Committee shall make any determination with respect to the termination or
reassignment of an existing member of management, or the decision to hire any
new member of management within 60 days following the availability of the
audited financial statements for the relevant year (or such longer period of
time as may be determined by a majority of the Board), and no such determination
shall be made thereafter; provided that:  (a) the Management Committee shall
have such additional time as is reasonably necessary for the recruitment and
selection of any such new member of management; and (b) no action or inaction by
the Management Committee following the fiscal year ended July 1996 shall impair
its ability to act as herein authorized following the fiscal year ended July
1997.  Notwithstanding the generality of the foregoing, the Management Committee
shall not be authorized to take such actions if they would violate applicable
law or if the shortfall in consolidated revenues, gross profits or net income of
the Company and its subsidiaries referred to above, shall be the direct result
of (a) fire, flood, earthquake or other act of God, any war, whether or not
declared, insurrection, hostilities, or other armed conflict, acts of civil
disorder or riot, or the disruption of national or international financial,
currency or capital markets, in each case affecting the Company or any of its
significant suppliers, or (b) a decline in the unit volume of the world market
for personal computers.

                         REGISTRATION RIGHTS AGREEMENT

          This Registration Rights Agreement (this "Agreement") is entered into
as of July 31, 1995 by and between Samsung Electronics Co., Ltd., a Korean
corporation (the "Investor") and AST Research, Inc., a Delaware corporation (the
"Company").

          A.  The Investor and the Company have entered into that certain Stock
Purchase Agreement dated as of February 27, 1995, as amended by Amendment No. 1
thereto dated as of June 1, 1995 and Amendment No. 2 thereto dated as of July
29, 1995 (as so amended, the "Stock Purchase Agreement"), pursuant to which the
Investor is acquiring certain shares of the Company's Common Stock.

          B.  The execution and delivery of this Agreement is a material
inducement and consideration to the Investor to enter into the Stock Purchase
Agreement and a condition to the transactions contemplated thereby.

          NOW, THEREFORE, in consideration of the foregoing premises and the
representations, warranties, and covenants set forth in this Agreement, the
Investor and the Company hereby agree as follows:


                                   ARTICLE 1

the Stock Purchase Agreement shall have the respective meanings set forth below.

          "Adverse Disclosure" means public disclosure of material non-public
information relating to a Significant Transaction, which disclosure (i) would,
in the good faith judgment of the Board, based as to legal matters on the
written opinion of outside counsel, be required to be made in any registration
statement filed with the Commission by the Company so that such registration
statement would not be materially misleading; (ii) would not, in the good faith
judgment of the Board, based as to legal matters on the written opinion of
outside counsel, be required to be made but for the filing of such a
registration statement; and (iii) would have a material adverse effect on the
Company's ability to complete such Significant Transaction, or the terms upon
which such Significant Transaction can be completed.

          "Demand Registration" has the meaning set forth in Section 2.1.
                                                             -----------

the Commission in compliance with the Securities Act.

          "Registrable Shares" means (i) the New Issue Shares, (ii) the Offer
Shares, and (iii) other shares of Common Stock acquired by the Investor and/or
its Affiliates from time to time not in violation of the Stock Purchase
Agreement or the Stockholder Agreement.  All Registrable Shares shall continue

shall cease to be Registrable Shares when transferred to any person other than
such an Affiliate of the Investor, or (a) when sold in a registered public
offering or in 

<PAGE>
 
accordance with Rule 144 promulgated by the Commission under the Securities
Act, or (b) when permitted to be sold in accordance with Rule 144(k).

          "Registration Expenses" means all expenses, except Selling Expenses,
incurred by the Company in complying with Articles 2 and 3, including, without
                                          ----------     -                    
limitation, all registration, qualification, and filing fees, printing expenses,

and expenses, the expense of any special audits incident to or required by any
such registration, expenses of all marketing and promotional efforts reasonably
requested by the managing underwriter and the reasonable fees (not to exceed
$50,000) and reasonable disbursements of one counsel for the Investor.

          "Selling Expenses" means all underwriting discounts, selling
commissions, and stock transfer taxes applicable to the sale of the Registrable
Shares.

                                   ARTICLE 2
                              DEMAND REGISTRATIONS

          2.1  Request for Registration.  At any time and from time to time
after 180 days following the Closing of the purchase and sale of the First
Issuance Shares, the Investor may request that the Company effect the
registration of Registrable Shares (a "Demand Registration").  Upon receipt of
such request, the Company shall use its best efforts to effect such Demand
Registration, subject to the limitations set forth in Section 2.2.  The Company
                                                      -----------              
may include in any Demand Registration any other shares of Common Stock
(including issued and outstanding shares of Common Stock as to which the holders
thereof have contracted with the Company for "piggyback" registration rights) so
long as the inclusion in such registration of such shares will not, in the
reasonable judgment of the managing underwriter(s), if any, interfere with the
successful marketing in accordance with the intended method of sale or other
disposition of all the Registrable Shares sought to be registered.  If it is
determined as provided above that there will be such interference, the other
shares of Common Stock sought to be included shall be excluded to the extent
deemed appropriate by the managing underwriter(s).

          2.2  Limitations on Demand Registrations.  Subject to Section 2.4, the
                                                                -----------     
Company's obligation to effect a Demand Registration requested by the Investor
pursuant to Section 2.1 shall be subject to the following limitations:
            -----------                                               

               2.2.1.  The Company shall not be required to effect any Demand
Registration of fewer than 2,000,000 Registrable Shares (as adjusted for any
stock splits, reverse stock splits or similar events which occur after the date
hereof).

               2.2.2.  The Company shall not be required to effect any Demand
Registration within 18 months of the effectiveness of a Registration by the
Investor of Registrable Shares registered pursuant to the previous Demand
Registration effected by Company.

               2.2.3.  The Company may defer its obligations to effect a Demand
Registration if, in the good faith judgment of the Board, filing a registration
statement with the Commission at the time a Demand Registration is requested
would require Adverse Disclosure, provided that such deferral may not extend
beyond the earlier to occur of (i) 180 days after the receipt by the Company of
the Investor's request for such Demand Registration, or (ii) the date

                                       2
<PAGE>
 
that filing of a registration statement with the Commission would not require
Adverse Disclosure therein.

               2.2.4.  If the Investor purchases the First Issuance Shares but 
not the Second Issuance Shares and the Offer Shares, the Company shall not be
required to effect more than three (3) Demand Registrations.  If the Investor
purchases all of the New Issuance Shares and the Offer Shares, the Company shall
not be required to effect more than six (6) Demand Registrations.

          2.3  Holdback.  Subject to Section 2.4, if requested (pursuant to a
                                     -----------                             
timely written notice) by the managing underwriter(s) of an underwritten
offering or the initial purchaser(s) in any offering being resold pursuant to
Rule 144A under the Securities Act of New Securities by the Company, the
Investor shall agree on the same terms applicable to officers and directors of
the Company not to effect any public sale or distribution of any of the
Registrable Shares for a period of up to 120 days following and 15 days prior to
the date of the final prospectus contained in the registration statement filed
in connection with such offering.

          2.4  Minimum Sale Availability.  The limitations on the Company's
obligations to effect Demand Registrations set forth in Sections 2.2.3 and the
                                                        --------------        
Investor's obligation under Section 2.3 shall not be applicable to the extent
                            -----------                                      
that such limitations would result in the Investor not having a period of at
least 180 consecutive days within any 18-month period during which the Investor
may sell Registrable Shares under a Registration effected pursuant to the
provisions hereof.

          2.5  Selection of Underwriter.  Any Demand Registration and related
offering shall be managed by the Investor as follows: subject to the reasonable
approval of the Company, the Investor shall have the power to select the
managing underwriter(s) for such offering, and shall in consultation with the
managing underwriter(s) have the power to determine the number of Registrable
Shares to be included in such registration and offering (subject to applicable
limitations set forth herein), the offering price per Registrable Share, the
underwriting discounts and commissions per Registrable Share, the timing of the
registration and related offering (subject to applicable limitations set forth
herein), counsel to the Investor, and all other administrative matters related
to the registration and related offering.  The Company shall enter into an
underwriting agreement in customary form with the underwriter(s) selected by the
Investor and shall enter into such other customary agreements and take all such
other customary actions as the Investor or its underwriter(s) may reasonably
request to facilitate the disposition of the Registrable Shares.

                                   ARTICLE 3
                            PIGGYBACK REGISTRATIONS

          3.1  Request for Registration.  At any time that the Company proposes
to register any Common Stock for sale solely for cash, either for its own
account or for the account of a stockholder or stockholders (a "Company
Registration"), the Company shall give the Investor written notice of its
intention to do so and of the intended method of sale (the "Registration
Notice") not fewer than 25 days prior to the anticipated filing date of the
registration statement effecting such Company Registration.  The Investor may
request inclusion of any Registrable Shares in such Company Registration by
delivering to the Company, within 15 days after receipt of the Registration
Notice, a written notice (the "Piggyback Notice") stating the number of
Registrable Shares proposed to be included and that such shares are to be
included in any underwriting only on the same terms and conditions as the shares
of Common Stock otherwise being sold through underwriters under such

                                       3
<PAGE>
 
Registration.  The Company shall use its best efforts to cause all Registrable
Shares specified in the Piggyback Notice to be included in the Company
Registration and any related offering, all to the extent requisite to permit the
sale by the Investor of such Registrable Shares in accordance with the method of
sale applicable to the other shares of Common Stock included in the Company
Registration.

          3.2  Limitations on Piggyback Registrations.  The Company's obligation
to include Registrable Shares in the Company Registration pursuant to Section
                                                                      -------
3.1 shall be subject to the following limitations:
---                                               

               3.2.1.  The Company shall not be obligated to include any 
Registrable Shares in a registration statement (i) filed on Form S-4 or 
Form S-8 or such other similar successor forms then in effect under the 
Securities Act, (ii) pursuant to which the Company is offering to exchange its 
own securities, or (iii) relating to dividend reinvestment plans.

               3.2.2.  If the managing underwriter(s), if any, of an offering 
related to the Company Registration determines in its reasonable judgment that
marketing factors require a limitation of the number of shares of Common Stock
that can be included in such offering, the managing underwriter(s) may exclude 
the appropriate number of shares of Common Stock held by the stockholders of the
Company, including the Investor, from such registration.  If the managing
underwriter(s) determines to exclude from such offering any Registrable Shares
that the Investor desires to include or any shares of Common Stock that other
Company stockholders with applicable registration rights desire to include, the
Investor and such other Company stockholders (except for such person or persons,
if any, upon whose demand such Registration is being made) shall share pro rata
in the portion of such offering available to them (the "Available Portion"),
with the Investor and each such other Company stockholder entitled to include in
such Company Registration and related offering a number of shares of Common
Stock equal to the product of (i) the Available Portion and (ii) a fraction, the
numerator of which is the total number of Registrable Shares (in the case of the
Investor) or shares of Common Stock entitled to inclusion in such Company
Registration and related offering (in the case of other Company stockholders
desiring inclusion), and the denominator of which is the total of the number of
Registrable Shares and shares of Common Stock entitled to inclusion in such
Company Registration and related offering owned by the Company stockholders
other than the Investor desiring inclusion.

          3.3  Selection of Underwriter.  Any Company Registration and related
offering shall be managed by the Company; the Company shall have the power to
select the managing underwriter(s) for such offering, and shall in consultation
with the managing underwriter(s) have the power to determine the offering price,
the underwriting discounts and commissions, the terms of the underwriting
agreement, the timing of the registration and related offering, counsel to the
Company, and all other administrative matters related to the registration and
related offering.  To the extent that the Investor participates in a Company
Registration and related offering pursuant to Section 3.1, the Investor shall
                                              -----------                    
enter into, and sell its Registrable Shares only pursuant to, the underwriting
arranged by the Company, and shall either commit to attend the closing of the
offering and take such other actions as may be reasonably necessary to effect
the Investor's participation in the offering and to provide any assurances
reasonably requested by the Company and the managing underwriter(s) in that
regard, or shall deliver to the Company in custody certificates representing all
Registrable Shares to be included in the registration and shall execute and
deliver to the Company a custody agreement and a power of attorney, each in form
and substance appropriate for the purpose of effecting the Investor's
participation in the Company Registration and related offering and otherwise
reasonably satisfactory to the Company.  If the Investor disapproves of the
features of the Company Registration and related offering, the Investor may
elect to

                                       4
<PAGE>
 
withdraw therefrom (in whole or part) by written notice to the Company
and the managing underwriter(s) delivered no later than ten (10) days prior to
the effectiveness of the applicable registration statement and the Registrable
Shares of the Investor shall thereupon be withdrawn from such registration.

          3.4  Other Registration Rights.  Notwithstanding anything in this
Article 3 to the contrary, the Investor shall be entitled to participate in any
---------                                                                      
Company Registration and related offering upon terms at least as favorable as
those upon which any other Company stockholder is entitled to participate
therein, subject to Section 3.2.2.

                      REGISTRATION PROCEDURES AND EXPENSES

          4.1  Registration Procedures.  If and whenever the Company is required
pursuant to this Agreement to use its best efforts to effect the registration of

being registered and offered, and the intended method of distribution of such
Registrable Shares as is reasonably requested by the Company for inclusion in

connection with a Company Registration, for the period associated with such 
offering;

               4.1.2.  prepare and file with the Commission such amendments and

                                 ------------- 

               4.1.3.  furnish to the Investor such number of prospectuses and
preliminary prospectuses in conformity with the requirements of the Securities

               4.1.4.  upon written request by any underwriters of the

signed counterpart, addressed to the Investor and its underwriters, if any, of
(i) a letter from the independent certified public accountants of the Company 
in the form customarily furnished to underwriters in firm commitment 
underwritten offerings providing substantially that such accountants are 
independent certified public accountants within the meaning of the Securities 
Act and that in the opinion of such accountants, the financial statements and 
other financial data of the Company included in the registration statement and
the prospectus, and any amendment or supplement thereto, comply as to form in 
all material respects with the applicable accounting requirements of the 
Securities Act, and additionally covering such other financial matters 
(including information as of the date of such letter) with respect to the 
registration in respect of which such letter is being given

                                       5

delivered to the  underwriters in comparable underwritten public offerings;
              
                4.1.5 use its best efforts to register or qualify the
Registrable Shares covered by such registration statement under such securities
or blue sky laws of such jurisdictions within the United States as the Investor
or its underwriters, if any, shall reasonably request; provided, however, that
the Company shall not be required to qualify generally to do business in any

subject it to general service of process in any such jurisdiction where it is
not then so subject, or subject the Company to any tax in any such jurisdiction
where it is not then so subject;

               4.1.6.  cause all such Registrable Shares to be listed on each

Registrable Shares not later than the effective date of such registration
statement;

               4.1.8.  make available for inspection by the Investor and its

          5.1  Indemnification by the Company.  In the event of a registration

in any registration statement under which such shares are registered under the
Securities Act, any preliminary prospectus or final prospectus contained
therein, any summary prospectus used in connection with any securities being

<PAGE>
 
Company of the Securities Act or rules of the Commission thereunder or any blue
sky laws or any rules promulgated thereunder, and shall reimburse each such
Indemnitee for any legal or any other expenses reasonably incurred by them in
connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the Company shall not be liable 
                     -----------------
in any such case to the extent that any such expense, loss, claim, damage or
liability arises out of or is based upon an untrue statement or alleged untrue
statement or omission or alleged omission made in such registration statement,
said preliminary prospectus or said prospectus or summary prospectus or said
amendment or supplement in reliance upon and in conformity with written
information furnished to the Company by or on behalf of the Investor or any
underwriter specifically for use in the preparation thereof; and provided,
                                                                 --------
further, that if any expenses, losses, claims, damages or liabilities arise 
-------
out of or are based upon an untrue statement, alleged untrue statement,
omission or alleged omission contained in any preliminary prospectus which did
not appear in the final prospectus, the Company shall not have any liability
with respect thereto to any Investor Indemnitee if any Investor Indemnitee
delivered a copy of the preliminary prospectus to the person alleging such
expenses, losses, claims, damages or liabilities and failed to deliver a copy
of the final prospectus as amended or supplemented if it has been amended or
supplemented, to such person at or prior to the written confirmation of the
sale to such person.

          5.2  Indemnification by the Investor.  In the event of a registration
of any Registrable Shares pursuant to this Agreement, the Investor shall
indemnify and hold harmless the Company and each person, if any, who controls
the Company within the meaning of the Securities Act, each officer of the
Company who signs the registration statement, each director of the Company and
each underwriter and each person who controls any underwriter within the meaning
of the Securities Act (each a "Company Indemnitee"), against any and all such
expenses, losses, claims, damages or liabilities referred to in Section 5.1 if
                                                                -----------   
the statement, alleged statement, omission or alleged omission in respect of
which such expense, loss, claim, damage or liability is asserted was made in
reliance upon and in conformity with information furnished in writing to the
Company by or on behalf of a holder of Registrable Shares specifically for use
in connection with the preparation of such registration statement, preliminary
prospectus, prospectus, summary prospectus, amendment or supplement; provided,
                                                                     ---------
however, that if any expenses, losses, claims, damages or liabilities arise out
-------                                                                        
of or are based upon an untrue statement, alleged untrue statement, omission or
alleged omission contained in any preliminary prospectus which did not appear in
the final prospectus, the Investor shall not have any such liability with
respect thereto to any Company Indemnitee if any Company Indemnitee delivered a
copy of the preliminary prospectus to the person alleging much expenses, losses,
claims, damages or liabilities and failed to deliver a copy of the final
prospectus, as amended or supplemented if it has been amended or supplemented,
to such person at or prior to the written confirmation of the sale to such
person.

          
          5.3  Contribution.  If the indemnification provided for in Sections
                                                                     --------
5.1 or 5.2 above is unavailable to an indemnified party in respect of any
---    ---                                                               
losses, claims, damages or liabilities referred to therein, then in lieu of
indemnifying such indemnified party thereunder, the indemnifying party shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages or liabilities, in such proportion as is
appropriate to reflect the relative fault of the indemnifying party on the one
hand and of the indemnified parties on the other in connection with the
statements or omissions which resulted in such losses, claims, damages or
liabilities, as well as any other relevant equitable considerations.  The
relative fault of the indemnifying party and of the indemnified parties shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission to state a material fact
relates to information supplied by the indemnifying party, or by the indemnified
parties, and the parties' relative 

                                       7
<PAGE>
 
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission.

          The parties agree that it would not be just and equitable if
contribution pursuant to this Section 5.3 were determined by pro rata allocation
                              -----------                    --- ----           
or by any other method of allocation which does not take into account the
equitable considerations referred to in the immediately preceding paragraph.
The amount paid or payable by an indemnified party as a result of the losses,
claims, damages and liabilities or actions in respect thereof referred to in the
immediately preceding paragraph shall be deemed to include, subject to the
limitations set forth above, any legal or other expenses reasonably incurred by
such indemnified party in connection with investigating or defending any such
action or claim.  Notwithstanding the provisions of this Section 5.3, no holder
                                                         -----------           
of Registrable Shares (other than a person who controls the Company within the
meaning of the Securities Act) shall be required to contribute any amount in
excess of the amount by which the total price at which the Registrable Shares
sold by it exceeds the amount of any damages which such holder has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission.  No person guilty of fraudulent misrepresentations
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.

          5.4  Indemnification Procedures.  Promptly after receipt by an
indemnified party of notice of the commencement of any action, such indemnified
party shall, if a claim in respect thereof is to be made against the
indemnifying party, notify the indemnifying party in writing of the commencement
thereof; but the omission so to notify the indemnifying party shall not relieve
it from any liability which it may have to any indemnified party otherwise than
under this Article 5 or to the extent that it has not been prejudiced as a
           ---------                                                      
proximate result of such failure.  In case any such action shall be brought
against any indemnified party, and it shall notify the indemnifying party of the
commencement thereof, the indemnifying party shall be entitled to participate
therein and, to the extent that it shall wish, to assume the defense thereof,
with counsel satisfactory to such indemnified party; provided, however, that if
the defendants in any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have reasonably concluded
that there may be legal defenses available to it and/or other indemnified
parties which are different from or additional to those available to the
Company, the indemnified party or parties shall have the right to select
separate counsel to assert such legal defenses (in which case the indemnifying
party shall not have the right to direct the defense of such action on behalf of
the indemnified party or parties).  Upon the permitted assumption by the
indemnifying party of the defense of such action, and approval by the
indemnified party of counsel, the indemnifying party shall not be liable to such
indemnified party under this Article 5 for any legal or other expenses
                             ---------                                
subsequently incurred by such indemnified party in connection with the defense
thereof (other than reasonable costs or investigation) unless (i) the
indemnified party shall have employed separate counsel in connection with the
assertion of legal defenses in accordance with the proviso to the next preceding
sentence, (ii) the indemnifying party shall not have employed counsel
satisfactory to the indemnified party to represent the indemnified party within
a reasonable time, (iii) the indemnifying party and its counsel do not actively
and vigorously pursue the defense of such action or (iv) the indemnifying party
has authorized the employment of counsel for the indemnified party at the
expense of the indemnifying party.

               "We hereby certify that AST Research, Inc., has defaulted under

                      REIMBURSEMENT; ADVANCEMENT OF FUNDS

          3.1  Reimbursement. The Company hereby promises to reimburse the
Purchaser, as provided in Section 3.3, for any draws by Tandy pursuant to
Section 2.2, on a date (the "Reimbursement Date") agreed upon by the Company and

requested by the Company, not to exceed $75,000,000.00 (less any amounts
previously drawn on the Letter of Credit in accordance with Section 2.2), solely
for prompt application in making required principal payments in respect of the
Tandy Note, on a date (the "Advance Date") agreed upon by the Company and the
Purchaser, which shall be no later than fifteen (15) Business Days following the
receipt by the Purchaser of a written notice setting forth the date and amount
(the "Advance Amount") of each required payment in respect of the Tandy Note for
which an advance is being requested under this Section 3.2.  Notwithstanding the
foregoing, the obligation of the Purchaser to advance such funds shall be
conditioned on the Company having provided to the Purchaser a written agreement
reasonably satisfactory to the Purchaser that the Company has available, and
will pay to Tandy when due, all other funds, if any, necessary to pay in full
such required principal payments.  The Purchaser represents and warrants to the

Purchaser's election (which shall be made in writing and provided to the Company
no later than five (5) Business Days following the date of the notice required
under Section 3.1 or 3.2, as applicable), either (a) provide a promissory note

Borrower and lender agree that (i) any legal action or proceeding arising

Lender shall collect monies or other property which are deemed to constitute
interest which would otherwise increase the effective interest rate on this
Note to a rate in excess of the maximum rate permitted to be charged by
the Usury Laws, all such sums or property deemed to constitute interest in
excess of such maximum rate shall, at the option of Lender, be credited
to the payment of the principal sum due hereunder.

AST Research, Inc.

Irvine, California, 92718

     Re:  Closing Agreement

Gentlemen,

          This is to set forth the agreement we have reached concerning the
closing of the transactions contemplated by that certain Stock Purchase
Agreement dated as of February 27, 1995, as amended (the "Stock Purchase
Agreement"), between AST Research, Inc. ("AST") and Samsung Electronics Co.,
Ltd. ("Samsung").

          As the result of losses incurred by AST during the fourth quarter of
its fiscal year ended July 3, 1995, and in connection with the consummation of
the transactions contemplated by the Stock Purchase Agreement, this letter
agreement sets forth certain actions to be taken by AST after the closing of the
transactions contemplated by the Stock Purchase Agreement and shall constitute a
legally binding agreement between us.  For good and valuable consideration,
receipt of which is hereby acknowledged, and as an inducement to Samsung to
complete the transactions contemplated by the Stock Purchase Agreement, we
hereby agree as follows:

          1.  Within ten business days of the Closing of the transactions
contemplated by the Stock Purchase Agreement, AST shall engage a nationally
recognized management consulting firm with experience in the personal computer
industry and with no prior relationship with AST or any of its affiliates,
officers or directors (the "Consultants") to perform a review of AST as
described herein (the "Review").  The Consultants shall be subject to the
approval of Samsung, which approval shall not be unreasonably withheld.  The
Review shall commence as soon as practicable after the Consultants are engaged.

          2.  The purposes of the Review shall be to (i) develop strategies to
strengthen AST's competitive position; (ii) determine the causes of AST's
operating loss for the fiscal year ended July 3, 1995 and its failure to achieve
results consistent with its business plan; (iii) determine what factors,
including without limitation management, organizational and operational factors,
were responsible therefor; and (iv) make specific recommendations as described
in paragraph 7.

          3.  In order to accomplish the purposes of the Review, the Consultants
shall conduct a full management diagnostic analysis and a review of AST's
organizational structure, with specific emphasis upon the roles and
effectiveness of management and the functions and procedures of each of AST's
operating and administrative divisions and operations.  This agreement shall not
limit the scope of the Review, and the Consultants shall undertake such
additional inquiries and procedures as they may deem appropriate or as the
Committee referred to in paragraph 4 may direct in order to fulfill the purposes
of the Review.

          4.  A committee of four persons, consisting of Safi Qureshey, two
representatives designated by Samsung, and one non-employee director of AST (the
"Committee") shall meet regularly with the Consultants in order to monitor,
supervise and direct the Review.  The members of the Committee shall be
available to participate actively in the Review process.  The Committee shall
define the work product to be delivered by the Consultants as a result of the
Review and may in its discretion modify the purposes and scope of the Review.
All Committee decisions shall be by majority vote.

<PAGE>
 
          5.  AST shall cause all of its employees and agents to cooperate
fully and in all respects with the Consultants, including, without limitation,
by providing to them all information they request.  Samsung shall be permitted
to participate in the Review process to the extent it deems desirable, and,
subject to applicable law, shall have full access to all information requested
by the Consultants.

          6.  The Consultants shall be instructed to complete the Review within
30 days of its inception, or as soon thereafter as the Consultants shall
determine is practicable in light of  the purposes and scope of the Review and
parties' desire that the Review be completed as quickly as possible.

          7.  Based upon the Review, the Consultants shall present to the
Committee specific, detailed and thorough recommendations to remedy the causes
referred to in paragraph 2, to address the management, organizational and
operational factors responsible for those causes, and to enhance employee morale
and effectiveness, with the ultimate goal of developing AST into one of the
world's top three manufacturers of personal computers.

          8.  The Committee shall promptly review the Consultants'
recommendations, ratify them to the extent the Committee deems appropriate,
and then pass the Consultants' recommendations to AST's Board of Directors
(the "Board"), together with the Committee's ratification decisions and any
additional recommendations or comments the Committee deems appropriate. Within
seven days of delivery to the Board of the Consultants' recommendations, the
Board shall meet to consider such Review and the Consultants' recommendations
and the Committee's action thereon and comments, and consistent with its
fiduciary duties, shall commence implementation of specific, detailed and
thorough actions to accomplish the objectives described in paragraph 7.

          9.  All expenses incurred in connection with the Review shall be
borne by AST.

          10.  The actions contemplated herein, including without limitation
Samsung's participation in the Review, the implementation of the Consultants'
recommendations, and any other actions the Board deems necessary or appropriate
to accomplish the objectives described in paragraph 7, shall not constitute a
violation of the Stockholder Agreement.

          If the foregoing accurately sets forth our agreement and has been
approved by the Board, please sign in the space provided below, whereupon this
letter shall constitute our binding agreement, enforceable in accordance with
the laws of Delaware.

                                      Sincerely yours,

                                      Samsung Electronics Co., Ltd.

not otherwise defined herein shall have the meanings set forth in the Agreement.

          WHEREAS, the Purchaser and the Company desire to document certain
understandings regarding the transactions contemplated in the Agreement and the
Closing thereof.

          NOW, THEREFORE, in consideration of the foregoing and the mutual
agreements set forth herein, and for other good and valuable consideration, the
receipt and sufficiency of which is hereby acknowledged, the undersigned,
intending to be legally bound, hereby agree as follows:

                               CONTINGENT SHARES

          3.1  Issuance of Contingent Shares Following Adverse Event.   The
first two sentences of Section 2.1.2 of Amendment No. 1 are hereby amended to
read in their entirety as follows:

          In the event that at any time or from time to time an action results
          in an Adverse Event that requires the payment by the Company of
          amounts in settlement of such action or in satisfaction of a judgment
          in such action and the aggregate amounts actually so paid by the
          Company including, without limitation, any amounts paid by the Company
          for attorneys' fees, (all such amounts being referred to herein as
          "Specified Amounts") exceeds the Excess Loss Amount, as defined below,
          then the Company shall issue to the Purchaser, without the payment by
          the Purchaser of any additional consideration, a number of additional
          shares of Common Stock (the "Contingent Shares") determined in
          accordance with Section 2.1.3.  For purposes of this Amendment, the

           2.1.4.  Purchases to Restore Previous Purchaser Interest.
                   ------------------------------------------------ 

          (a)  At any time and from time to time until 270 days after the
Closing, the Purchaser may purchase in the open market at any available price up
to that aggregate number of additional shares of Voting Stock which, if they had
been acquired by the Purchaser in the open market on the date of the Closing,

          (b)  If at any time or from time to time on or after the date hereof
the number of outstanding shares of Voting Stock is increased for any reason
through the issuance of additional shares, including, without limitation, upon
exercise of stock options or directors' warrants or upon conversion or exchange

the Tandy Note with Common Stock, or as consideration for acquisition of any
corporation or other entity or business or division thereof, but excluding any

or distributed proportionately on all outstanding shares of Voting Stock, then
in connection with each such issuance the Purchaser and/or its Affiliates shall
have the right, but not the obligation, to purchase in the open market at any
available price, up to such number of additional shares of Voting Stock as may
then be necessary solely as a result of such issuance to restore the Purchaser
Interest to the same percentage of the Total Voting Power as existed immediately
prior to such increase in the number of outstanding shares of Voting Stock,
provided that any shares of Voting Stock acquired by the Purchaser pursuant to
Section 2.1.4(a) shall be deemed to have been acquired at the Closing for
----------------                                                         
purposes of determining the Purchaser Interest immediately prior to such
increase in the number of outstanding shares of Voting Stock.  The purchase
right set forth in this Section 2.1.4(b)  shall be exercisable at any time and
                        -----------------

           2.1.5. New Equity Issuance. The Purchaser and/or its Affiliates shall

           2.1.6. Third-Party Offers. From and after the Closing of the purchase
                  ------------------  
and sale of the Second Issuance Shares until such time as the Purchaser Interest
has been less than 30% for a period of at least twenty-five (25) consecutive
days, in the event any Third Party shall make an offer to acquire a 20% or
greater interest in Equity Securities, the Purchaser and/or its Affiliates shall
be permitted to make a competing offer, and acquire Equity Securities pursuant
thereto, subject to and in accordance with the following:

                                       3
<PAGE>
 
          (a)  If (i) the Third Party offer is approved or recommended by a
majority vote of the Directors not designated by the Purchaser pursuant to this
Agreement, or (ii) there shall be in effect no Rights Agreement or the Board
shall have amended or rescinded the Rights Agreement to exclude the Third Party
from the definition of "Acquiring Person" or permit the Third Party offer to
proceed without resulting in a Distribution Date or a Triggering Event or the
Rights becoming exercisable or (iii) a court of competent jurisdiction shall
have entered an order invalidating the Rights Agreement with respect to the
Third Party offer or ordering that the Rights be rescinded or the Rights
Agreement be so amended, then the Purchaser shall have the right to make a
competing offer and to acquire Equity Securities pursuant to such competing
offer, provided that (1) the competing offer complies with Section 2.1.6(b), (2)
                                                           ----------------     
the competing offer is made prior to the withdrawal or termination of the Third
Party offer, and (3) if the Third Party offer is withdrawn or terminated before
the Purchaser acquires Equity Securities pursuant to the competing offer, the
Board determines in good faith that such Third Party offer was withdrawn or
terminated primarily as a result of the Purchaser's competing offer having
superior terms  to or a substantially greater likelihood of success than such
Third Party offer.  The Company shall not enter into any agreement with the
Third Party offeror or take any action required as a condition of the Third
Party offer unless and until the Purchaser shall have been notified in writing
by the Company of the right of the Purchaser and/or its Affiliates to submit a
competing offer hereunder, and the Purchaser and/or its Affiliates shall have
been afforded not less than ten (10) Business Days following receipt of such
notice in which to submit its competing offer for consideration by the Board.

          (b)  Any competing offer by the Purchaser pursuant to this Section
                                                                     -------
2.1.6 shall be, as nearly as possible, for an identical amount of securities and
-----                                                                           
at a price per share no lower than and on terms no less favorable than are
offered by the Third Party, provided that any such offer may be subject to any
governmental or regulatory approvals required by Korean law.  In the event the
consideration offered in any Third Party offer shall consist of securities or
property other than cash, the competing offer by the Purchaser may in the
Purchaser's discretion be for cash in an amount per share not less than the fair
market value of the consideration offered by the Third Party.

      2.1.7. Maximum Purchaser Ownership. Notwithstanding anything in this
             ---------------------------
Section 2.1 to the contrary, from the date of this Agreement until the
expiration of the Standstill Period, neither the Purchaser nor any of its
Affiliates may (directly or indirectly) acquire, or offer to acquire, Beneficial
Ownership of any Voting Stock if, after such acquisition, the Purchaser Interest
(calculated as though Beneficial Ownership of Voting Stock includes shares of
Voting Stock that the Purchaser has the right to acquire (other than pursuant to
this Agreement) as described in subsection (d)(1)(i) of Rule 13d-3 under the
Exchange Act without regard to the 60-day limit set forth therein) would exceed
49.9%, unless such acquisition or offer (together with related transactions) is
(a) made pursuant to Section 2.1.6, or (b) has been approved by a majority of
                     -------------  
the Directors not designated by the Purchaser pursuant to this Agreement and
would result in the Purchaser and/or its Affiliates owning 100% of the Voting
Stock.

      2.2. Pro-Rata Purchase Right. From and after the Closing of the purchase
and sale of the Second Issuance Shares until such time as the Purchaser Interest
has been less than 30% for a period of at least twenty-five (25) consecutive
days, the Company shall give the Purchaser at least

                                       4
<PAGE>
 
twenty-five (25) (and, when possible, at least ninety-five (95)) days' prior
written notice of the issuance by the Company of any New Securities as a result
of which the Purchaser Interest would be reduced, either immediately upon
issuance of such New Securities, or upon subsequent exercise or conversion
thereof. Such notice shall set forth (a) the approximate number and type of
securities proposed to be issued and sold to persons other than the Purchaser
and/or its Affiliates and the material terms of such securities, (b) the
proposed price or range of prices at which such securities are proposed to be
sold and the terms of payment, (c) the number of such securities offered to the
Purchaser and/or its Affiliates in compliance with this Section 2.2, and (d)
                                                        -----------         
the proposed date of issuance of such securities.  The Purchaser may, by notice
given to the Company within fifteen (15) days after such Company notice and so
long as permitted by applicable laws and regulations, elect to purchase up to
its pro rata share of such New Securities.  Such pro rata share shall be a
percentage of the proposed issuance equal to the Purchaser Interest (calculated
as though Beneficial Ownership of Voting Stock includes shares of Voting Stock
that the Purchaser has the right to acquire (other than pursuant to this
Agreement) as described in subsection (d)(1)(i) of Rule 13d-3 under the Exchange
Act without regard to the 60-day limit set forth therein) immediately prior to
such issuance.  The Purchaser's pro-rata purchase shall be on the same terms as
the balance of such issuance, provided that if the sale price at which the
Company proposes to issue, deliver or sell any New Securities is to be paid with
consideration other than cash, then the purchase price at which the Purchaser
may acquire such New Securities shall be equal in value (as determined in good
faith by the Board) but payable entirely in cash.  The closing of the
Purchaser's purchase of New Securities pursuant to this Section 2.2 shall occur
                                                        -----------            
simultaneously with the closing of the balance of such issuance, provided that
if as of the date of the closing of the balance of such issuance the Purchaser
has not received all approvals of Governmental Authorities required in
connection with the Purchaser's participation in such issuance, then (i) the
Purchaser shall not be required to effect its purchase under this Section 2.2
                                                                  -----------
until such approvals have been received, and (ii) the Company may terminate the
Purchaser's right to participate in such issuance if the Purchaser has not
effected its purchase within 120 days of receipt from the Company of written
notice of the New Issuance.  If the Purchaser elects such deferral, the Company
may close the portion of the issuance other than the Purchaser's portion prior
to the closing of the issuance of the Purchaser's portion.  If the terms of the
proposed issuance are materially changed from those stated in the Company's
notice to the Purchaser of such issuance, then the proposed issuance shall be
treated as a new issuance, subject again to this Section 2.2, and any election
                                                 -----------                  
to purchase made prior to such change may, at the sole discretion of the
Purchaser, be withdrawn.

     The Purchaser's pro-rata purchase right pursuant to this Section 2.2 shall
                                                              -----------      
not apply, however, to:

               (i) any issuance pursuant to (a) any stock option or purchase
right or plan exclusively for one or more employees and/or directors of the
Company or any of its subsidiaries or (b) warrants issued to Directors prior to
the date hereof;;

               (ii) any issuance in consideration of any part of the acquisition
by the Company or any subsidiary of any stock, assets or business;

               (iii)  any issuance upon conversion of the LYONs;

                                       5
<PAGE>
 
               (iv) any issuance pursuant to the exercise or conversion of any
New Security issued after the date hereof in a transaction in which the
Purchaser was entitled to participate pursuant to this Section 2.2; or
                                                       ----------- 

     (v) any issuance in payment of any portion of the Tandy Note.

      2.3. Notice and Subscription Procedures. In addition to the notice
required under Section 2.2, the Company shall notify the Purchaser of, and
               -----------
provide the Purchaser with an accurate and complete description of, any
event that will cause the rights of the Purchaser and/or its Affiliates to
acquire or offer to acquire Equity Securities under Section 2.1 (other than
                                                    -----------
Section 2.1.2 or 2.1.5) to become exercisable. The Company shall deliver
-------------    -----
such notice to the Purchaser as promptly as practicable after becoming
aware of such event, and when possible at least ninety-five (95) days prior
to the anticipated date of such event, provided that notice of issuances of
a kind described in subsection (i), (iii), or (iv) of Section 2.2, need
                                                      -----------
only be delivered within 15 days following the end of each fiscal quarter
of the Company.

      2.4. Acquisitions After Standstill Period. After the Standstill Period,
this Agreement shall not restrict the acquisition or offer to acquire any Equity
Securities or interest therein by the Purchaser and/or its Affiliates; provided,
however, that the Purchaser shall not acquire or offer to acquire any Equity
Securities if, as the result of or after giving effect to such acquisition, the
Purchaser Interest (calculated as though Beneficial Ownership of Voting Stock
includes shares of Voting Stock that the Purchaser has the right to acquire
(other than pursuant to this Agreement) as described in subsection (d)(1)(i) of
Rule 13d-3 under the Exchange Act without regard to the 60-day limit set forth
therein) would exceed 66.67%, except pursuant to a cash tender offer for all
Equity Securities not owned by the Purchaser and/or its Affiliates.

                                   ARTICLE 3.
                               TRANSFER OF SHARES

     The Purchaser and its Affiliates shall not sell or otherwise transfer
(except to an Affiliate of the Purchaser which shall agree to be bound by this
Agreement) any Equity Securities Beneficially Owned by such persons or any
interest therein for a period of five (5) years from the Closing of the purchase
and sale of the First Issuance Shares, except as follows:

      3.1. Pro-Rata Transactions. From and after the third anniversary of the
Closing of the purchase and sale of the First Issuance Shares, the Purchaser
and/or any of its Affiliates may sell any or all Equity Securities Beneficially
Owned by such persons in any transaction or transactions in which each other
holder of Equity Securities has the opportunity to sell the same percentage of
such stockholder's Equity Securities as the Purchaser and such Affiliates, at a
price and on terms no less favorable than those applicable to the sale by the
Purchaser and/or its Affiliates.

      3.2. Public Offerings and Market Transactions. From and after the third
anniversary of the Closing of the purchase and sale of the First Issuance Shares
(or, in the case of Common Stock acquired from the Company pursuant to Section
3.3 of the Letter of Credit Agreement, at any time and from time to time), the
Purchaser and/or any of its Affiliates may sell any or all

                                       6
<PAGE>
 
Equity Securities Beneficially Owned by such persons in one or more registered
public offerings or in market transactions if the Purchaser and/or its selling
Affiliates invoke and follow or require participating underwriters or brokers to
invoke and follow appropriate and reasonable procedures (subject to the
Company's prior approval, which shall not be unreasonably withheld) designed to
prevent the sale of such Equity Securities to any person or "group" (within the
meaning of Section 13(d)(3) of the Exchange Act) that would, after giving effect
to its acquisition of such Equity Securities, Beneficially Own or have the right
to acquire more than ten percent (10%) of the Total Voting Power.

      3.3. Directors' Approval. The Purchaser and/or any of its Affiliates may
sell any or all Equity Securities Beneficially Owned by such persons in any
transaction or transactions approved by a majority of the Directors other than
Directors designated by the Purchaser pursuant to this Agreement.

     In the event the Purchaser shall sell or otherwise transfer any Equity
Securities or any interest therein to an Affiliate, then so long as any such
Equity Securities are Beneficially Owned by such Affiliate, the provisions of
this Article shall apply to any sale or transfer of the capital stock or other
equity interests of such Affiliate such that it would cease to be an Affiliate
of the Purchaser.

      4.1.   Purchaser Designees.


           4.1.1. Full Investment. At all times and from time to time after
                  ---------------
acquisition by the Purchaser of the Original Investment Shares, subject to
Section 4.1.2, the Purchaser shall have the right to designate that number of
-------------
Directors as will result in the total number of Directors designated by the
Purchaser being one fewer than a majority of the total number of Directors then
authorized under the Company's Certificate of Incorporation. Subject to Section
                                                                        -------
4.2, this Section 4.1.1 shall not limit the right of the Purchaser to nominate
---               -----
and seek the election of additional Directors after the Standstill Period.

           4.1.2. Partial Investment. If (a) the Purchaser acquires the First
                  ------------------
Issuance Shares, but does not also acquire all other Original Investment Shares,
or (b) the Purchaser acquires the Original Investment Shares but the Purchaser
Interest shall thereafter at any time have been less than thirty percent (30%)
for a period of at least twenty-five (25) consecutive days, then the Purchaser
shall from time to time have the right to designate that number of Directors as
will result in the total number of Directors designated by the Purchaser being
equal to the product (rounded to the nearest whole number) of (i) the total
number of Directors then authorized under the Company's Certificate of
Incorporation, and (ii) the Purchaser Interest at that time.

           4.1.3. Purchaser Directors. Any Director designated by the Purchaser
                  -------------------  
shall not serve as a Director if such person shall be prohibited from serving as
a Director under applicable law, including antitrust law.

                                       7

      4.2. Independent Directors. At all times until such time as the Purchaser
Interest shall have been less than 30% for a period of at least twenty-five (25)
consecutive days or more than 90% for a period of at least twenty-five (25)
consecutive days, the Board shall include at least three Independent Directors.

      4.3.  Additional Agreements.

           4.3.1. By the Company. The Company shall from time to time increase
                  --------------
the number of Directors constituting the Board and/or obtain resignations from
Directors (other than designees of the Purchaser and Independent Directors
required by Section 4.2) as may be required to ensure that there will at all
            ----------- 
times be sufficient Board seats available to accommodate the full number of
Directors that the Purchaser is then entitled to designate pursuant to Section
                                                                       -------  
4.1. The Company shall promptly and at all times use its best efforts, and take
---
all such actions as may be appropriate or necessary for the election to the
Board of the Purchaser designees selected pursuant to Section 4.1 and the
                                                      -----------
Independent Directors required pursuant to Section 4.2. Such actions shall
                                           -----------  
include, without limitation, the solicitation of proxies for the election of
such persons at each regular or special meeting of stockholders of the Company
at which Directors are to be elected, or in any written consent solicited in
lieu of such a meeting.

                     
          4.3.2. By the Purchaser. The Purchaser and its Affiliates shall vote
                 ----------------  
their Shares at each regular or special meeting of the Company's stockholders at
which Directors are to be elected, or in any written consent solicited in lieu
of such a meeting, in favor of election to the Board, and shall otherwise use
their best efforts to cause the appointment or election to the Board, and to
maintain as Directors: (a) during the Standstill Period, such Independent
Directors and such additional Directors as shall be designated by a majority of
the Directors of the Company other than those designated by the Purchaser,
consistently with Sections 4.1 and 4.2; and (b) after the Standstill Period,
                  ------------     --- 
such Independent Directors as are required by Section 4.2 and otherwise as the
                                              ----------- 
Purchaser and its Affiliates may determine in their discretion. If at any time
prior to the end of the Standstill Period the number of Directors that the
Purchaser is entitled to designate pursuant to Section 4.1 is fewer than the
                                               ----------- 
number of Purchaser designees then serving on the Board, the Purchaser shall
promptly obtain resignations from such of its designees (chosen by the
Purchaser) as may be required to cause the number of Purchaser designees serving
on the Board to be equal to the number of Directors that the Purchaser is then
entitled to designate.

           4.3.3. By the Purchaser and the Company. Names of all Director
                  --------------------------------
nominees designated by the Purchaser or by those Directors of the Company not
designated by the Purchaser shall be furnished to the Purchaser and the Company
(a) in the case of election of Directors at an annual meeting or otherwise
pursuant to a vote of the Company's stockholders, in time to be included in the
proxy materials related to such election, and (b) at least ten (10) days prior
to election or appointment of Directors by the Board.

      4.4. Committees. The Purchaser shall be entitled to designate one of its
Director designees to serve on each committee of the Board (except as otherwise
provided in Section 12 of Article III of the Amended Bylaws with respect to the
Management Committee). The Purchaser shall be entitled to select any of the
Directors as alternates for each of its Director designees serving on committees
of the Board, which alternates shall be the designees of the Board for

                                       8
<PAGE>
 
purposes of the Amended Bylaws and Section 141(b) of the Delaware General
Corporation Law and may replace any of the Purchaser's Director designees
serving on any committee who are absent or disqualified at any meeting of the
committee. With respect to the audit committee, any Purchaser Director designee
shall, as a condition to membership thereon, meet all requirements imposed by
the rules of any national securities exchange, or the Nasdaq National Market, on
which the Company's Shares may then be listed or quoted. With respect to the
compensation committee, any Purchaser Director designee shall, as a condition to
membership thereon, qualify as "disinterested" within the meaning of Rule 16b-3
under the Exchange Act or any similar rule then in effect.

      4.5. Vacancies. If any Director or Director nominee designated by the
Purchaser pursuant to Section 4.1 shall decline to serve on, resign or be
                      -----------
removed from, or for any other reason be unable to serve on the Board or any
committee thereof, the vacancy resulting therefrom shall be filled in accordance
with the Company's Certificate of Incorporation and Bylaws by another person
designated by the Purchaser pursuant to Section 4.1. If any Director or Director
                                        ----------- 
nominee not designated by the Purchaser pursuant to Section 4.1 shall decline to
                                                    ----------- 
serve on, resign or be removed from, or for any other reason be unable to serve
on the Board or any committee thereof during the Standstill Period, the vacancy
resulting therefrom shall be filled in accordance with the Company's Certificate
of Incorporation and Bylaws by a person designated by a majority of the
Directors of the Company other than those designated by the Purchaser. This
Section 4.5 shall not operate to allow the Purchaser or the Directors other than
-----------
those designated by the Purchaser to designate more Directors or committee
members than it or they would be entitled to designate hereunder but for this
Section 4.5.
-----------

      4.6. Directors' Indemnification and Insurance. As long as any designees of
the Purchaser serve on the Board, (a) the Amended and Restated Certificate of
Incorporation and Bylaws of the Company shall not be amended to contain
provisions less favorable with respect to indemnification and limitation of
liability of Directors than are set forth in the Amended and Restated
Certificate and Amended Bylaws as of the date of this Agreement, or in any other
manner that would affect adversely the rights thereunder of designees of the
Purchaser serving on the Board, unless such amendment, repeal or modification
shall be required by law or the fiduciary obligations of the Board, as
determined in good faith by the Board based on the written advice of outside
counsel, and (b) such designees shall be covered by any directors' and officers'
liability insurance maintained from time to time on the same terms and subject
to the same conditions as the other members of the Board, and (c) such designees
shall be entitled to the benefit of any indemnification agreements entered into
by the Company with any of its Directors; provided, that nothing in this
Agreement shall obligate the Company to maintain any such insurance or to enter
into any such indemnification agreements.

      4.7. Directors' Compensation. The Directors designated by the Purchaser,
if any, who are not officers or employees of the Purchaser and its Affiliates
shall have the right to receive all fees paid and options and other awards
granted and expenses reimbursed to non-employee Directors generally, provided
that all such fees and awards allocable to Directors who are not officers or
employees of the Purchaser and its Affiliates shall not be paid or awarded or
transferred to the Purchaser. Directors designated by the Purchaser who are
officers or employees of the Purchaser or its Affiliates shall have the right to
receive only such fees, options

                                       9

and other awards and expense reimbursements, if any, as may be granted
to employee Directors of the Company for their service as Directors, provided
that, notwithstanding Article 2 (other than Section 2.1.7), any or all such fees
                      ---------             -------------                       
and awards allocable to Directors designated by the Purchaser shall, in the
Purchaser's discretion, be paid or awarded to the Purchaser.

                             RESULTS OF OPERATIONS

     Following the acquisition by the Purchaser of the Original Investment
Shares, and provided that the Purchaser Interest shall not have been less than
thirty percent (30%) for a period of at least twenty-five (25) consecutive days,
if (a) the consolidated revenues or gross profits of the Company and its
subsidiaries for the fiscal year ended July 1996 shall be less than $2.6 billion
or $430 million, respectively, (b) the consolidated revenues or gross profits of
the Company and its subsidiaries for the fiscal year ended July 1997 shall be
less than the greater of (i) $2.75 billion or $450 million, respectively, or
(ii) 85% of the amounts therefor set forth in the 1997 operating plan of the
Company approved by the Board; or (c) the consolidated net income after taxes of
the Company and its subsidiaries for either of such fiscal years shall be less
than 1% of net revenues, then the Management Committee of the Board shall
review the desirability of changes in the management of the Company and take
such action, if any, as may be determined to be advisable including without
limitation the reassignment, changes in the responsibilities, removal,
termination or replacement of any members of  management.  For purposes of the
foregoing, the "management" of the Company shall refer to all persons who
presently have the title of "Vice President" or higher, whether or not any such
person is an officer of the corporation, and all such persons who may perform
the functions presently performed by any of the foregoing, without regard to
title, but shall not include the Chief Executive Officer.  The Management
Committee shall make any determination with respect to the termination or
reassignment of an existing member of management, or the decision to hire any
new member of management within 60 days following the availability of the
audited financial statements for the relevant year (or such longer period of
time as may be determined by a majority of the Board), and no such determination
shall be made thereafter; provided that:  (a) the Management Committee shall
have such additional time as is reasonably necessary for the recruitment and
selection of any such new member of management; and (b) no action or inaction by
the Management Committee following the fiscal year ended July 1996 shall impair
its ability to act as herein authorized following the fiscal year ended July
1997.  Notwithstanding the generality of the foregoing, the Management Committee
shall not be authorized to take such actions if they would violate applicable
law or if the shortfall in consolidated revenues, gross profits or net income of
the Company and its subsidiaries referred to above, shall be the direct result
of (a) fire, flood, earthquake or other act of God, any war, whether or not
declared, insurrection, hostilities, or other armed conflict, acts of civil
disorder or riot, or the disruption of national or international financial,
currency or capital markets, in each case affecting the Company or any of its
significant suppliers, or (b) a decline in the unit volume of the world market
for personal computers.

                      ------------------------                            
required or permitted to take any action at a meeting, a written notice of the
meeting shall be given which shall state the place, date and hour of the
meeting, and, in the case of a special meeting, the purpose or purposes for
which the meeting is called.  Unless otherwise required by law, such notice

meeting to each stockholder of record entitled to vote at such meeting.  If
mailed, such notice shall be deemed to be given when deposited in the mail,
postage prepaid, directed to the stockholder at his address as it appears on the
records of the Corporation.  A written waiver of any such notice signed by the
person entitled thereto, whether before or after the time stated therein, shall
be deemed equivalent to notice.  Attendance of a person at a meeting shall
constitute a waiver of notice of such meeting, except when the person attends
the meeting for the express purpose of objecting, at the beginning of the
meeting, to the transaction of any business because the meeting is not lawfully
called or convened.

or provided by the Certificate of Incorporation, the holders of a majority of
the capital stock issued and outstanding and entitled to vote thereat, present
in person or represented by proxy, shall constitute a quorum for the transaction
of business at all meetings of the stockholders.  If, however, such quorum shall
not be present or represented at any meeting of the stockholders, the
stockholders entitled to vote thereat, present in person or represented by
proxy, shall have power to adjourn the meeting from time to time, without notice
other than announcement at the meeting of the time and place of the adjourned
meeting, until a quorum shall be present or represented.  At such adjourned
meeting at which a quorum shall be present or represented, any business may be
transacted which might have been transacted at the meeting as originally
noticed.  If after the adjournment a new record date is fixed for the adjourned
meeting, a notice of the adjourned meeting shall be given to each stockholder
entitled to vote at the meeting.

          Section 7.  Voting.  Except as otherwise required by law, or provided
                      ------                                                   
by the Certificate of Incorporation or these Bylaws, any question brought before
any meeting of stockholders shall be decided by the vote of the holders of a
majority of the stock represented and entitled to vote thereat.  Unless
otherwise provided in the Certificate of Incorporation, each stockholder
represented at a meeting of stockholders shall be entitled to cast one vote for
each share of the capital stock entitled to vote thereat held by such
stockholder.  Such votes may be cast in person or by proxy, but no proxy shall
be voted on or after three years from its date, unless such proxy provides for a
longer period.  Elections of directors need not be by ballot unless the Chairman
of the meeting so directs or unless a stockholder demands election by ballot at

                      -------------------------------------------------------  
Any action which may be taken at any annual or special meeting of stockholders

stockholder or their respective proxy holders, may revoke the consent by a
writing received by the Secretary of the Corporation before written consents of
the number of shares required to authorize the proposed action have been filed
with the Secretary.

business hours, for a period of at least ten days prior to the meeting, either
at a place within the city where the meeting is to be held, which place shall be

where the meeting is to be held.  The list shall also be produced and kept at
the time and place of the meeting during the whole time thereof, and may be

          Section 10.  Stock Ledger.  The stock ledger of the Corporation shall
                       ------------                                            
be the only evidence as to who are the stockholders entitled to examine the

                       ----------------------                               
stockholders, the Board of Directors may appoint one or more persons (who shall
not be candidates for office) as inspectors of election to act at the meeting.
If inspectors are not so appointed, or if an appointed inspector fails to appear
or fails or refuses to act at a meeting, the Chairman of any meeting of
stockholders may, and on the request of any stockholder or his proxy shall,
appoint inspectors of election at the meeting.  In the event of any dispute
between or among the inspectors, the determination of the majority of the
inspectors shall be binding.

          Section 12.  Organization.  At each meeting of stockholders the
                       ------------                                      
Chairman of the Board of Directors, if one shall have been elected, (or in his
absence or if one shall not have been elected, the President) shall act as
chairman of the meeting.  The Secretary (or in his absence or inability to act,
the person whom the Chairman of the meeting shall appoint secretary of the
meeting) shall act as secretary of the meeting and keep the minutes thereof.

                       -----------------                                      
business at all meetings of stockholders shall be determined by the Chairman of
the meeting.

                                 ARTICLE III

                                  DIRECTORS

          Section 1.  Powers.  Except as otherwise required by law or provided
                      ------                                                  
by the Certificate of Incorporation, the business and affairs of the Corporation
shall be managed by or under the direction of the Board of Directors.

          Section 2.  Number and Election of Directors.  Directors shall be
                      --------------------------------                     
elected at each annual meeting of stockholders and each director so elected
shall hold office until his successor is duly elected and qualified, or until
his earlier death, resignation or removal.  Any director may resign at any time
effective upon giving written notice to the Board of Directors, unless the
notice specifies a later time for such resignation to become effective.  Unless
otherwise specified therein, the acceptance of such resignation shall not be

                                      3
<PAGE>
 
necessary to make it effective.  If the resignation of a director is effective
at a future time, the Board of Directors may elect a successor prior to such
effective time to take office when such resignation becomes effective.
Directors need not be stockholders.

          Section 3.  Vacancies.  Except as otherwise set forth herein,
                      ---------                                        
vacancies in the Board of Directors may be filled by a majority of the remaining
directors, though less than a quorum, or by a sole remaining director, except
that a vacancy created by the removal of a director by the vote or written
consent of the stockholders may be filled only by the vote of a majority of the
shares entitled to vote represented at a duly held meeting at which a quorum is
present, or by the written consent of holders of a majority of the outstanding
shares entitled to vote.  Each director so elected shall hold office until the
next annual meeting of the stockholders and until a successor has been elected
and qualified.

          Reference is made to the Stockholder Agreement (the "Stockholder
Agreement") dated as of July 31, 1995 by and between the Corporation and Samsung
Electronics Co., Ltd. ("Samsung")  and to Article 4 thereof.  In the event of
the death, resignation or removal of a director designated by Samsung in
accordance with Section 4.1 of the Stockholder Agreement, such vacancy shall be
filled by the remaining directors only by another person designated by Samsung.
In the event of the death, resignation or removal of a director not designated
by Samsung in accordance with the Stockholder Agreement, during the Standstill
Period, as defined therein, such vacancy may be filled by the remaining
directors only by another person designated by those directors not designated by
Samsung.

          A vacancy or vacancies in the Board of Directors shall be deemed to
exist in the event of the death, resignation, or removal of any director, or if
the authorized number of directors is increased, or if the stockholders fail, at
any meeting of stockholders at which any director or directors are elected, to
elect the number of directors to be voted for at that meeting.

          The stockholders may elect a director or directors at any time to fill
any vacancy or vacancies not filled by the directors, but any such election by
written consent shall require the consent of a majority of the outstanding
shares entitled to vote.

          No reduction of the authorized number of directors shall have the
effect of removing any director before that director's term of office expires.

          Section 4.  Time and Place of Meetings.  The Board of Directors shall
                      --------------------------                               
hold its meetings at such place, either within or without the State of Delaware,
and at such time as may be determined from time to time by the Board of
Directors.

          Section 5.  Annual Meeting.  The Board of Directors shall meet for the
                      --------------                                            
purpose of organization, the election of officers and the transaction of other
business, as soon as practicable after each annual meeting of stockholders, on
the same day and at the same place where such annual meeting shall be held.
Notice of such meeting need not be given.  In the event such annual meeting is
not so held, the annual meeting of the Board of Directors may be held at such
place, either within or without the State of Delaware, on such date and at such
time as shall be specified in a notice thereof given as hereinafter provided in
Section 7 of this Article III or in a waiver of notice thereof.

          Section 6.  Regular Meetings.  Regular meetings of the Board of
                      ----------------                                   
Directors may be held at such places within or without the State of Delaware at
such date and time as

                                      4

the Board of Directors may from time to time determine and, if so determined by
the Board of Directors, notices thereof need not be given.

          Section 7.  Special Meetings.  Special meetings of the Board of
                      ----------------                                   
Directors may be called by the Chairman of the Board, the President, by any Vice
President, the Secretary or by any two directors, provided that at any special
meeting called during the Standstill Period (as defined in the Stockholder
Agreement) by directors designated by Samsung, there shall not be a quorum
(including for purposes of Section 8) unless a majority of the directors present
are directors not designated by Samsung.  Notice of the date, time and place of
special meetings shall be delivered personally or by telephone to each director
or sent by first class mail or telegram, charges prepaid, addressed to each
director at the director's address as it is shown on the records of the
Corporation.  In case the notice is mailed, it shall be deposited in the United
States mail at least five days before the time of the holding of the meeting.
In case the notice is delivered personally or by telephone or telegram, it shall
be delivered personally or by telephone or to the telegraph company at least 48
hours before the time of the holding of the meeting.  The notice need not
specify the purpose of the meeting.

          Section 8.  Quorum; Vote Required for Action: Adjournment.  Except as
                      ---------------------------------------------            
otherwise required by law, or provided in the Certificate of Incorporation or
these Bylaws (including, without limitation, Section 7), a majority of the
directors shall constitute a quorum for the transaction of business at all
meetings of the Board of Directors and the affirmative vote of not less than a
majority of the directors present at any meeting at which there is a quorum
shall be the act of the Board of Directors.  If a quorum shall not be present at
any meeting of the Board of Directors, the directors present thereat may adjourn
the meeting, from time to time, without notice other than announcement at the
meeting, until a quorum shall be present.  A meeting at which a quorum is
initially present may continue to transact business, notwithstanding the
withdrawal of directors, if any action taken is approved by at least a majority
of the required quorum to conduct that meeting.  When a meeting is adjourned to
another time or place (whether or not a quorum is present), notice need not be
given of the adjourned meeting if the time and place thereof are announced at
the meeting at which the adjournment is taken.  At the adjourned meeting, the
Board of Directors may transact any business which might have been transacted at
the original meeting.

          Notwithstanding anything to the contrary herein, two-thirds (2/3) of
the directors shall be required to constitute a quorum for, and the affirmative
vote of not less than two-thirds (2/3) of all the directors shall be required to
approve, any action that would (i)  amend that certain Amended and Restated
Rights Agreement between the Corporation and American Stock Transfer & Trust
Company as Successor Rights Agent dated as of January 28, 1994, as amended by
the First Amendment thereto dated as of March 1, 1995, or any new stockholder
rights plan; or (ii) adopt any new stockholder rights plan, if such amendment or
new stockholder rights plan does not contain provisions equivalent to those set
forth in such First Amendment for the benefit of Samsung.

          Section 9.  Action by Written Consent.  Unless otherwise restricted by
                      -------------------------                                 
the Certificate of Incorporation, any action required or permitted to be taken
at any meeting of the Board of Directors or of any committee thereof may be
taken without a meeting if all the members of the Board of Directors or
committee, as the case may be, consent thereto in writing, and the writing or
writings are filed with the minutes of proceedings of the Board of Directors or
committee.

Certificate of Incorporation, members of the Board of Directors of the
Corporation, or any committee designated by the Board of Directors, may
participate in a meeting of the Board of Directors or such committee, as the
case may be, by conference telephone or similar communications equipment by
means of which all persons participating in the meeting can hear each other.
Participation in a meeting pursuant to this Section 10 shall constitute presence
in person at such meeting.

          Section 11.  Committees.  The Board of Directors may, by resolution
                       ----------                                            
passed by a majority of the entire Board, designate one or more committees, each
committee to consist of one or more of the directors of the Corporation.  The
Board of Directors may designate one or more directors as alternate members of
any such committee, who may replace any absent or disqualified member at any
meeting of the committee.  Any committee, to the extent allowed by law and as
provided in the resolution establishing such committee, shall have and may
exercise all the power and authority of the Board of Directors in the management
of the business and affairs of the Corporation.  Each committee shall report to
the Board of Directors when required.

          Section 12.  Management Committee.  Reference is made to the
                       --------------------                           
Stockholder Agreement and to Article 7 thereof.  The Corporation shall have a
Management Committee of the Board of Directors which shall have and may exercise

circumstances set forth, in said Article 7.  The Management Committee shall
consist of those members of the Board of Directors designated by Samsung in
accordance with the Stockholder Agreement, the Chief Executive Officer of the
Corporation, if he shall be a director (or, if he is not then a director,
another director who is an employee of the Corporation), and up to a maximum of
four (4) directors who are not officers or employees of the Corporation.  In the
event there shall be more than four directors who were not designated by Samsung
and are not officers or employees of the Corporation at a time when the
Management Committee is authorized to act in accordance with the foregoing,
those directors of the Corporation who were not designated by Samsung shall
select the four such directors who shall be members of the Management Committee
in addition to the Chief Executive Officer (or, if he is not then a director,
another director who is an employee of the Corporation) and the Directors
designated by Samsung, and unless and until such selection is made the
Management Committee shall consist solely of the directors designated by Samsung
and the Chief Executive Officer of the Corporation (or, if he is not then a
director, another director who is an employee of the Corporation).

          Section 13.  Compensation.  The directors may be paid such
                       ------------                                 
compensation for their services as the Board of Directors shall from time to
time determine.

          Section 14.  Interested Directors.  No contract or transaction between
                       --------------------                                     
the Corporation and one or more of its directors or officers, or between the
Corporation and any other corporation, partnership, association, or other
organization in which one or more of its directors or officers are directors or
officers, or have a financial interest, shall be void or voidable solely for
this reason, or solely because the director or officer is present at or
participates in the meeting of the Board of Directors or the committee thereof
which authorizes the contract or traction, or solely because his or their votes
are counted for such purpose if:  (i) the material facts as to his or their
relationship or interest and as to the contract or transaction are disclosed or
are known to the Board of Directors or the committee, and the Board of Directors
or committee in good faith authorizes the contract or transaction by the
affirmative votes of a majority of the disinterested directors, even

                                      6
<PAGE>
 
though the disinterested directors be less than a quorum; or (ii) the material
facts as to his or their relationship or interest and as to the contract or
transaction are disclosed or are known to the stockholders entitled to vote
thereon, and the contract or transaction is specifically approved in good faith
by vote of the stockholders; or (iii) the contract or transaction is fair as to
the Corporation as of the time it is authorized, approved or ratified, by the
Board of Directors, a committee thereof, or the stockholders.  Common or
interested directors may be counted in determining the presence of a quorum at
a meeting of the Board of Directors or of a committee which authorizes the
contract or transaction.

officers, including one or more Vice Presidents, as the Board may in its
discretion appoint.  The Board of Directors, if it so determines, may appoint a
Chairman of the Board and a Vice Chairman of the Board from among its members,

status.  Any number of offices may be held by the same person.

                      -----------------------------------------

officers enumerated in Section 1 of this Article IV, the Corporation may have
one more assistant treasurers and assistant secretaries and such other
subordinate officers, agents and employees as the Board of Directors may deem
necessary, each of whom shall hold office for such period as the Board of
Directors may from time to time determine.  The Board of Directors may delegate
to any executive officer the power to appoint and to remove any such subordinate
officers, agents or employees.

          Section 4.  Removal.  Except as otherwise delegated to an executive
                      -------                                                
officer with respect to subordinate officers, any officer may be removed, with
or without cause, at any time, by resolution adopted by the Board of Directors
or by the Management Committee as provided in Article III Section 12.  Such
removal shall be without prejudice to the contractual rights of such officer, if
any, with the Corporation.

          Section 5.  Resignations.  Any officer may resign at any time by
                      ------------                                        
giving written notice to the Board of Directors (or to a principal officer if
the Board of Directors has delegated to such principal officer the power to
appoint and to remove such officer).  The resignation of any officer shall take
effect upon receipt of notice thereof or at such later time as shall be
specified in such notice; unless otherwise specified therein, the acceptance of
such resignation shall not be necessary to make it effective.

an officer as the Chief Executive Officer.  The Chief Executive Officer shall,
subject to the direction and control of the Board of Directors, be the general
manager of, and supervise and direct, the business and affairs of the
Corporation and the conduct of the officers of the Corporation.  The other
officers of the Corporation shall have such powers and perform such duties
incident to each of their respective offices and such other duties as may from
time to time be conferred upon or assigned to them by the Board of Directors or
the Chief Executive Officer.

certificate may be a facsimile.  In case any officer, transfer agent or
registrar who has signed or whose facsimile signature has been placed upon a
certificate shall have ceased to be such officer, transfer agent or registrar
before such certificate is issued, it may be issued by the Corporation with the
same effect as if he were such officer, transfer agent or registrar at the date
of issue.

          Section 3.  Lost Certificates.  The Corporation may issue a new
                      -----------------                                  
certificate to be issued in place of any certificate theretofore issued by the
Corporation, alleged to have been lost, stolen or destroyed, upon the making of
an affidavit of that fact by the person claiming the certificate to be lost,
stolen or destroyed.  The Corporation may, in its discretion and as a condition
precedent to the issuance of such new certificate, require the owner of such
lost, stolen, or destroyed certificate, or his legal representative, to give the
Corporation a bond (or other security) sufficient to indemnify it against any
claim that may be made against the Corporation (including any expense or
liability) on account of the alleged loss, theft or destruction of any such
certificate or the issuance of such new certificate.

          Section 4.  Transfers.  Stock of the Corporation shall be transferable

stockholder making the transfer.  Transfers of stock shall be made on the books
of the Corporation only by the person named in the certificate or by his
attorney lawfully constituted in writing and upon the surrender of the
certificate therefor, which shall be cancelled before a new certificate shall be
issued.

          Section 5.  Registered Owners.  The Corporation shall be entitled to
                      -----------------                                       
recognize the exclusive right of a person registered on its books as the owner
of shares to receive dividends, and to vote as such owner, and to hold liable
for calls and assessments a person registered on its books as the owner of

interest in such share or shares on the part of any other person, whether or not
it shall have express or other notice thereof, except as otherwise required by
law.

          No person shall be liable to the Corporation for any loss or damage
suffered by it on account of any action taken or omitted to be taken by him as a
director or officer of the Corporation if he acted in good faith and in a manner
he reasonably believed to be in or not opposed to the best interests of the
Corporation or, with respect to any criminal matter, had no reasonable cause to
believe that his conduct was unlawful.

the Corporation, (other than a judicial action or suit brought by or in the
right of the Corporation) by reason of the fact that he is or was a director or
officer of the Corporation, or is or was serving at the request of the
Corporation as a director or officer of another corporation, partnership, joint
venture, trust or other enterprise (all such persons being referred to hereafter
as an "Agent"), against expenses (including attorneys' fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by him in
connection with such action, suit or proceeding if he acted in good faith and in
a manner he reasonably believed to be in or not opposed to the best interests of
the Corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful.  The termination of any
action, suit or proceeding by judgment, order, settlement, conviction or upon a
plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal action or proceeding, that he had
reasonable cause to believe that his conduct was unlawful.

          Section 2.  Action by or in the Right of the Corporation.  The
                      --------------------------------------------      
Corporation shall indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed judicial action or suit
brought by or in the right of the Corporation to procure a judgment in its favor
by reason of the fact that he is or was an Agent (as defined in Section 1)
against expenses (including attorneys' fees) actually and reasonably incurred by
him in connection with the defense or settlement of such action or suit if he
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the Corporation, except that no indemnification
shall be made in respect of any claim, issue or matter as to which such person
shall have been adjudged to be liable to the Corporation unless and only to the
extent that the Court of Chancery or the court in which such action or suit was
brought shall determine upon application that, despite the adjudication of
liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses which the Court of
Chancery or other such court shall deem proper.

          Section 3.  Determination of Right of Indemnification.  Any
                      -----------------------------------------      
indemnification under Sections 1 or 2 (unless ordered by a court) shall be made
by the Corporation unless a

                                      9
<PAGE>
 
determination is reasonably and promptly made (i) by the Board by a majority
vote of a quorum consisting of directors who are or were not parties to such
action, suit or proceeding, or (ii) if such a quorum is not obtainable, or,
even if obtainable, if a quorum of disinterested directors so directs, by
independent legal counsel in a written opinion, or (iii) by the stockholders,
that such person acted in bad faith and in a manner that such person did not
believe to be in or not opposed to the best interests of the Corporation, or,
with respect to any criminal proceeding, that such person believed or had
reasonable cause to believe that his conduct was unlawful.

          Section 4.  Indemnification Against Expenses of Successful Party.
                      ----------------------------------------------------  
Notwithstanding the other provisions of this Article, to the extent that an
Agent has been successful on the merits or otherwise, including the dismissal of
an action without prejudice or the settlement of an action without admission of
liability, in defense of any proceeding or in defense of any claim, issue or
matter therein, such Agent shall be indemnified against all expenses incurred in
connection therewith.

          Section 5.  Advances of Expenses.  Except as limited by Section 6 of
                      --------------------                                    
this Article VII, expenses incurred in defending or investigating any action,
suit, proceeding or investigation shall be paid by the Corporation in advance of
the final disposition of such matter, if the Agent shall undertake to repay such
amount in the event that it is ultimately determined, as provided herein, that
such person is not entitled to indemnification.  However, no advance shall be
made by the Corporation if a determination is reasonably and promptly made by
the Board of Directors by a majority vote of a quorum of disinterested
directors, or (if such a quorum is not obtainable or, even if obtainable, a
quorum of disinterested directors so directs) by independent legal counsel in a
written opinion, that, based upon the facts known to the Board or counsel at the
time such determination is made, such person acted in bad faith and in a manner
that such person did not believe to be in or not opposed to the best interest of
the Corporation, or, with respect to any criminal proceeding, that such person
believed or had reasonable cause to believe his conduct was unlawful.  In no
event shall any advance be made in instances where the Board or independent
legal counsel reasonably determines that such person deliberately breached his
duty to the Corporation or its stockholders.

          Section 6.  Right of Agent to Indemnification Upon Application;
                      ---------------------------------------------------
Procedure Upon Application.  Any indemnification under Sections 2, 3, and 4, or
--------------------------                                                     
advance under Section 5 of this Article VII, shall be made promptly and in any
event within 45 days, upon the written request of the Agent, unless with respect
to applications under Sections 2, 3, or 5, a determination is reasonably and
promptly made by the Board of Directors by a majority vote of a quorum of
disinterested directors that such Agent acted in a manner set forth in such
Sections as to justify the Corporation's not indemnifying or making an advance
to the Agent.  In the event no quorum of disinterested directors is obtainable,
the Board of Directors shall promptly direct that independent legal counsel
shall decide whether the Agent acted in the manner set forth in such Sections as
to justify the Corporation's not indemnifying or making an advance to the Agent.
The right to indemnification or advances as granted by this Article VII shall be
enforceable by the Agent in any court of competent jurisdiction if the Board or
independent legal counsel denies the claim, in whole or in part, or if no
disposition of such claim is made within 45 days.  The Agent's expenses incurred
in connection with successfully establishing his right to indemnification, in
whole or in part, in any such proceeding shall also be indemnified by the
Corporation.

          Section 7.  Other Rights and Remedies.  The indemnification provided
                      -------------------------                               
by this Article VII shall not be deemed exclusive of any other rights to which
an Agent seeking indemnification may be entitled under any Bylaw, agreement,
vote of stockholders or disinterested directors, court order or otherwise, both
as to action in his official capacity and as to action in another capacity while
holding such office, since it is the policy of the Corporation that
indemnification of Agents shall be made to the fullest extent permitted by law.
The indemnification provided by this Article shall continue as to a person who
has ceased to be an Agent and shall inure to the benefit of the heirs, executors
and administrators of such a person.  All rights to indemnification under this
Article shall be deemed to be provided by a contract between the Corporation and
the Agent who serves in such capacity at any time while these Bylaws and other
relevant provisions of the General Corporation Law of the State of Delaware and
other applicable law, if any, are in effect.  Any repeal or modification thereof
shall not affect any rights or obligations then existing.

          Section 8.  Insurance.  The Corporation may purchase and maintain
                      ---------                                            
insurance on behalf of any person who is or was an Agent against any liability
asserted against him and incurred by him in any such capacity, or arising out of
his status as such, whether or not the Corporation would have the power to
indemnify him against such liability under the provisions of this Article.

          Section 9.  Indemnity Fund.  Upon resolution passed by the Board, the
                      --------------                                           
Corporation may establish a trust or other designated account, grant a security
interest or use other means (including, without limitation, a letter of credit),
to ensure the payment of certain of its obligations arising under this Article
and/or agreements which may be entered into between the Company and its officers
and directors from time to time.

          Section 10.  Constituent Corporations.  For the purposes of this
                       ------------------------                           
Article, references to "the Corporation" include all constituent corporations
absorbed in a consolidation or merger as well as the resulting or surviving
corporation, so that any person who is or was a director or officer of such a
constituent corporation or is or was serving at the request of such constituent
corporation as a director or officer of another corporation, partnership, joint
venture, trust or other enterprise shall stand in the same position under the
provisions of this Article with respect to the resulting or surviving
corporation as he would had he served such constituent corporation in the same
capacity.

          Section 11.  Other Enterprises, Fines, and Serving at Corporation's
                       ------------------------------------------------------
Request.  For purposes of this Article, references to "other enterprise" in
-------                                                                    
Sections 1 and 10 shall include employee benefit plans; references to "fines"
shall include any excise taxes assessed a person with respect to any employee
benefit plan; and references to "serving at the request of the Corporation"
shall include any service as a director or officer of the Corporation which
imposes duties on, or involves services by, such director or officer with
respect to any employee benefit plan, its participants, or beneficiaries; and a
person who acted in good faith and in a manner he reasonably believed to be in
the interest of the participants and beneficiaries of an employee benefit plan
shall be deemed to have acted in a manner "not opposed to the best interests of
the Corporation" as referred to in this Article.

          Section 12.  Indemnification of Other Persons.  The provisions of this
                       --------------------------------                         
Article VII shall not be deemed to preclude the indemnification of any person
who is not an Agent (as defined in Section 1), but whom the Corporation has the
power or obligation to indemnify under the provisions of the General Corporation
Law of the State of Delaware or otherwise.  The Corporation may, in its sole
discretion, indemnify an

                                      11
<PAGE>
 
employee, trust or other agent as permitted by the General Corporation Law of
the State of Delaware.  The Corporation shall indemnify an employee, trustee or
other agent where required by law.

          Section 13.  Savings Clause.  If this Article or any portion thereof
                       --------------                                         
shall be invalidated on any ground by any court of competent jurisdiction, then
the Corporation shall nevertheless indemnify each Agent against expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement
with respect to any action, suit or proceeding, whether civil, criminal,
administrative or investigative, and whether internal or external, including a
grand jury proceeding and an action or suit brought by or in the right of the
Corporation, to the full extent permitted by any applicable portion of this
Article that shall not have been invalidated, or by any other applicable law.

made available to any such stockholder by the transfer agent on or before the
later of 5 days after the demand is received or the date specified in the demand
as the date as of which the list is to be compiled.  The record of stockholders
shall also be open to inspection on the written demand of any stockholder or

for a purpose reasonably related to the holder's interests as a stockholder or
as the holder of a voting trust certificate.  Any inspection and copying under
this Section I may be made in person or by an agent or attorney of the
stockholder or holder of a voting trust certificate making the demand.

          Section 2.  Maintenance and Inspection of Bylaws.  The Corporation

            AST ANNOUNCES COMPLETION OF SAMSUNG STRATEGIC INVESTMENT



IRVINE, Calif., July 31, 1995 -- Representing the largest international equity
investment by a Korean company in the U.S., AST Research, Inc. (ASTA-NASDAQ)
today announced the completion of the previously-announced $377.5 million
strategic investment in AST by Samsung Electronics Co., Ltd.

       The agreement with Samsung results in an investment of 40.25 percent in
AST, as well as other strategic relationships, including component supply and
joint product development.  Samsung now holds a total of 17.89 million shares in
AST, which includes 5.82 million shares which were acquired in a tender offer
from AST stockholders at $22 per share.

       "The combined resources of AST and Samsung allow us to chart a new course
in strengthening our product offerings, technology developments and value to
customers," said Safi Qureshey, AST chairman and chief executive officer.  "Now
that the investment is complete, we can begin to go forward with our strategic
alliance which will allow us to benefit from the strengths of a $14 billion
company that is a world leader in component technologies.  We look forward to
working together and bringing the benefits from these efforts to the
marketplace."

       The strategic alliance will cover a broad range of commercial
relationships between the parties, including expanded and improved supply of
critical components manufactured by Samsung and used by AST in the manufacture
of personal computers, joint product development, OEM arrangements and cross-
licensing of patents.

       Some advantages of the relationship already discussed with Samsung to
date include:

future product developments in order to better leverage the strengths of the two
companies and determine the best future courses of action.

that is only limited by our imaginations," said Y.S. Kim, Samsung corporate vice
president.  "The strengths of Samsung blend well with those of AST.
Collectively, we have the potential to become one of the world's best in
delivering state-of-the-art computer products to our global customers."
