                                 OEM AGREEMENT


This agreement is made and entered into as of June 7, 1996, by and between
International Business Machines Corporation, having an office for the
transaction of business at 5600 Cottle Road, San Jose, California 95193
(hereinafter called "IBM" or "Monterey"), and Storage Technology Corporation,
having an office for the transaction of business at 2270 South 88th Street,
Louisville, Colorado 80028 (hereinafter called "StorageTek," "STK" or "Oahu").
StorageTek and IBM may be individually referred to herein as a "Party" and
collectively as the "Parties."

BACKGROUND

StorageTek manufactures and sells, among others, certain Equipment as more
fully described below. IBM  wishes to purchase such Equipment from StorageTek
on an Original Equipment Manufacturer (OEM) basis at large volume prices in
order to resell or lease such Equipment to its customers throughout the world,
both directly and indirectly through its distributors, Subsidiaries, and other
channels.  In order to secure access to IBM's distribution channels, to provide
StorageTek with the opportunity to reach more customers, to provide more
product choices for customers and also due to IBM's willingness to invest a
substantial amount in product research and development and in product
engineering, StorageTek is willing to sell such Equipment to IBM at such prices
if IBM will purchase a substantial amount of the Products and Upgrades,
advertise and market the Products and Upgrades, provide maintenance and repair
service for the Equipment sold or leased by it, maintain an inventory of spare
parts and take certain other related actions.

The provisions of this section are intended to generally explain the reasons
that StorageTek and IBM have entered into this Agreement, but do not constitute
a portion of the contractual obligations, terms or conditions agreed to by the
Parties, which are set forth in the following sections of this Agreement.


                                WITNESSETH THAT:

In  consideration of the mutual premises and covenants herein contained, the
Parties hereto agree as follows:

1.       DEFINITIONS

         1.1              "Agreement" shall mean this OEM Agreement, its
                          Exhibits, their Attachments, their Appendices and
                          their Schedules.


         1.2              "Agreement Administrator" shall have the meaning set
                          forth in Section 5.


         1.3              "Annual Volumes" shall have the meaning set forth in
                          Section 6.1.


         1.4              "APAR" shall mean a completed form entitled
                          "Authorized Program Analysis Report," that is used by
                          IBM to report suspected Code or documentation errors
                          in a





<PAGE>   9
                          Licensed Program (including updates or enhancements
                          thereto) and to request their investigation and
                          correction.


         1.5              "Audit Rights" (Section 7.5c) shall mean a Party's
                          right to have Price Waterhouse, Arthur Andersen or
                          Ernst & Young, or their lawful successors, audit the
                          other Party's books and records on reasonable prior
                          notice for the purpose of making a factual
                          determination of whether a specified event has
                          occurred.  The Parties shall request the firms in the
                          order set forth above, and shall only request the
                          second or third listed firm if the earlier listed
                          firms decline to serve.  In carrying out such audit
                          responsibilities, said accounting firm shall use
                          generally accepted accounting principles (hereafter

2.       SCOPE OF AGREEMENT

         2.1     StorageTek agrees to develop IBM requested enhancements to the
                 Equipment, to provide continuing engineering and marketing and
                 service support for the Equipment, and to manufacture, test,
                 sell and Deliver Equipment to IBM and desires that IBM supply
                 Drives for use in such Equipment all in accordance with the
                 Specifications, procedures and conditions contained in this
                 Agreement.

         2.2     IBM (i) agrees to fund the continuing engineering on, and the
                 future development of, specific enhancements to the Equipment
                 as set forth in the IDA, (ii) intends to add value to such
                 Equipment by consigning IBM Drives to StorageTek for inclusion
                 in the Equipment, and (iii) has the right to market and sell
                 Equipment purchased from StorageTek, all in accordance with
                 the terms of this Agreement.

         2.3     Changes to Specifications, procedures and conditions contained
                 in the Agreement, its Exhibits, their Attachments and their
                 Schedules may be made from time to time upon mutual written
                 agreement, specifically identifying this Agreement and stating
                 an intent to make such changes.


3.       TERM OF AGREEMENT

         Unless earlier terminated, the term of this Agreement shall be for a
         period from the date first set forth above (hereinafter "Effective
         Date"), through December 31, 1999.


4.       COMPONENTS

         Because the Equipment purchased by IBM from StorageTek is likely to be
         associated with the IBM brand, IBM wishes to be assured that such
         Equipment, when sold to its customers, will have the quality that its
         customers expect from items so branded.  Accordingly, IBM believes
         that, to the extent that StorageTek can utilize components in such
         Equipment that are manufactured by or for IBM under its high quality
         standards, it would be desirable for StorageTek to obtain such
         components from IBM for use in manufacturing the Equipment. **

5.       AGREEMENT ADMINISTRATOR

         Each Party will identify an Agreement Administrator no later than June
         15, 1996, who shall have overall responsibility for managing this
         Agreement for such Party.  Until such time, the Agreement
         Administrators are set forth below.  The Agreement Administrators may
         not amend the terms of this Agreement.  In addition to other
         responsibilities as may be agreed,

                       Volumes") shall depend on the price determined as set
                       forth above.

                       If StorageTek provides the cost described in paragraph
                       6.2b(1), above, as its price, IBM's   ** Volumes shall
                       be   **   Terabytes of Products and Upgrades.  If

                       **

                 d.    Notwithstanding the above, if IBM fails to notify
                       StorageTek prior to  **   of its desire to purchase
                       Products for   **   1999, and if, on or before   **
                       IBM decides that it wishes to continue to purchase
                       Products   **   1999, then,   **  1999 only, IBM may
                       elect to purchase such Products at the price quoted
                       pursuant to paragraph 6.2b, above   **   by providing a

                 g.    The Parties acknowledge and agree that the foregoing 
                       **   amount is not a penalty but represents a good 
                       faith estimate by the Parties of the amount of damages 
                       incurred by StorageTek upon the occurrence of the 
                       events set forth in Sections 6.5b through 6.5e.  The 
                       Parties have entered into this provision after each 
                       Party has had the opportunity to consult counsel, and 
                       pursuant to a mutual intent to avoid the expenses of

         6.6     OTHER STORAGETEK DISTRIBUTION

                 a.    StorageTek and its Subsidiaries may, at their sole
                       discretion, sell, lease or otherwise distribute Devices
                       and products competitive with Equipment to third
                       parties, provided, however, that neither StorageTek nor

                       except for situations as described in Section 6.7,
                       below, if StorageTek chooses to use, sell, lease or
                       otherwise distribute, either directly or indirectly:

                       (1)    any  **  or

                       (2)    **

                       then, unless the sale is excepted pursuant to Section
                       6.8, below, IBM shall be    **   its obligations and
                       liabilities related to   **   as well as any obligation 
                       to pay any   **   in the year in which the sale 
                       occurred and thereafter.  StorageTek shall also have no
                       right to terminate this Agreement for failure of IBM to
                       meet its   **   and shall immediately notify IBM in 
                       writing that such use, sale, lease or other 
                       distribution has occurred, and shall indicate that IBM   
                          **   the foregoing obligations.  IBM shall also have
                       the right to  **  . Each Party may also terminate  **

                 b.    If StorageTek licenses, transfers, sells or assigns to a
                       third party all or a portion of a Licensed Work  **  then
                       IBM shall be    **   its obligations and liabilities
                       related to  **  , as well as any obligation to   **   in
                       the year in which the sale occurred and thereafter.
                       StorageTek shall also have   **   for failure of IBM to
                       meet its  **   and shall immediately notify IBM in
                       writing that such license, transfer, sale or assignment
                       has occurred, and shall indicate that IBM   **   the
                       foregoing obligations.  IBM shall also have the right to

                 c.    If IBM learns of facts that indicate that StorageTek is
                       selling, leasing or otherwise distributing the products
                       described in Section 6.6a, above, directly or
                       indirectly, to customers other than IBM, or has
                       licensed, transferred, sold or assigned the Licensed
                       Works described in Section 6.6b, above, then upon
                       written notice by IBM to StorageTek:

                       (1)    StorageTek shall investigate the facts and
                              circumstances relating to the incident
                              thoroughly, and share the results, but not the
                              customer-specific details, with IBM.  If both
                              Parties agree that no such sale, lease or other
                              distribution occurred or no such license was
                              granted, then the rights and obligations of the
                              Parties shall not change.  If the Parties are
                              unable to agree on the facts relating to such
                              incident, then the matter will be handled
                              pursuant to the dispute resolution process
                              described in Section 22.

                       (2)    if StorageTek or its Subsidiaries has made a
                              sale, lease or other distribution to third
                              parties, as described in Section 6.6a, above, or
                              has licensed, transferred, sold or assigned the
                              Licensed Works to a third party, as described in
                              Section 6.6b, above, other than IBM, then IBM's
                              obligations shall be modified as set forth in
                              such sections.

         6.7     EXCEPTIONS

                 a.    Sales, leases, or other distribution or use of Devices
                       by StorageTek or its Subsidiaries in the following
                       situations are excepted from the provisions of Section
                       6.6, and will be credited toward calculation of IBM's
                       purchase volume for the purpose of determining whether
                       IBM has achieved its **  Volumes:

                       (1)    Sales, leases or other distribution of  **  .
                              For the purpose of determining the  ** which
                              shall be credited to IBM's  **   Volumes,  **

                       (2)    Sales of Devices by StorageTek or its

                              and further provided that, in the case of (a) or
                              (b), shipments made prior to  **   will not be
                              credited to IBM's  **   Volumes; and

                              shall be interpreted as granting StorageTek an
                              implied license to distribute FRUs that are or
                              contain IBM Materials or other IBM Code not

         7.8     LOWEST COST SOURCING.

                 The Parties agree that it is in their mutual interest for
                 StorageTek to obtain parts for new production and maintenance
                 purposes at the lowest practicable cost. If IBM identifies a
                 potential alternative source for any part, StorageTek will
                 make a good faith reasonable effort to qualify the
                 alternative.  If such bid is comparable with the quality,
                 terms and conditions and offers a better price compared to the
                 then current source of such parts, and awarding such
                 alternative source a supply contract pursuant to such bid does
                 not adversely impact the terms of StorageTek's purchases of
                 other parts from the then current source, then the lower cost
                 will be used in determining prices to IBM for Equipment
                 whether or not StorageTek actually obtains the part or parts
                 from such alternative source.

         7.9     TAXES/DUTIES

                 The prices for Equipment supplied under this Agreement are
                 exclusive of any customs charges and duties and sales, use,
                 privilege, excise and similar taxes levied by the USA, foreign
                 territories, or any other governmental entity on the Products,
                 their export, import, shipment, purchase or sale.  IBM shall
                 pay and be responsible for the payment of any such taxes
                 (excluding taxes based upon StorageTek's net income) or
                 duties; and, to the extent legally required, StorageTek shall
                 collect any applicable taxes unless IBM establishes its
                 exemption therefrom.  If StorageTek is required to pay any
                 such taxes or duties, IBM will reimburse StorageTek pursuant
                 to StorageTek's invoice.

                 IBM hereby represents to StorageTek that it is purchasing the
                 Products hereunder for the purpose of resale, rent, lease or
                 in-house use, and, if required by applicable law, IBM will
                 furnish StorageTek with pertinent and valid sales and use tax
                 exemption certificates.

         7.10    PAYMENT TERMS

                 a.    StorageTek will invoice IBM for Equipment on or after
                       the date on which such Equipment is Delivered.  If any
                       unit of Equipment is Delivered and is not suitable to be
                       installed, then the Equipment shall not be considered as
                       Delivered until such time that such Equipment is
                       rendered suitable for installation.  IBM or its designee
                       will exercise reasonable efforts to install Equipment
                       that it receives.  IBM will promptly notify StorageTek
                       when such Equipment is not suitable for installation.

                       Subject to Section 13.1k, payment terms will be the
                       number of days from date of receipt of a correct invoice
                       by IBM as shown in the following table:

                       deliver invoices to the address indicated on the
                       purchase order.

                 c.    Payment of an invoice by IBM under IBM purchase order(s)
                       will not be construed as and will not constitute an
                       acceptance of Product failing to conform to
                       specifications or agreed upon quality levels, nor will
                       any payment to StorageTek be construed as or constitute
                       a waiver of any of IBM's legal rights or remedies.

                 d.    StorageTek will invoice, and IBM will pay, in US Dollars
                       to the address listed on StorageTek's invoice.  All
                       payments will be made by wire transfer of immediately

         8.1     StorageTek, in its sole discretion, may acquire Equipment from
                  IBM  **  .  The prices for the first  ** units of Products
                  will be ** .  The prices for all other units of Products will
                  not exceed  ** .  The
                 prices for Upgrades will not exceed  ** .  Such Equipment may
                 be sold by StorageTek  **  .  Sales by IBM to StorageTek will
                 be pursuant to  **   with a one (1) day transit period, except
                 that all Equipment supplied pursuant to this section by IBM to
                 StorageTek shall be provided  **  .  Moreover, StorageTek
                 shall not be subject to  **  for such units.

         8.2     IBM agrees to sell StorageTek the Upgrades it reasonably
                 requires to meet the ongoing remarketing obligations
                 StorageTek has as of the  **   with respect to  ** . The
                 prices for Upgrades  **  which IBM will charge Storagetek
                 shall be commercially reasonable and not exceed  **  of IBM's
                 average selling price  **   but under no circumstance shall
                 such prices be any less than  **  of the price charged to IBM

                 purchased by IBM from StorageTek, will be counted as IBM's
                 volumes in calculating IBM's attainment of its   **  , and 
                 will not be subject to the limitations of Section 6.3, and
                 will be counted in addition to the Qualified Upgrades.


9.       QUALITY

         9.1     MANUFACTURING TESTING

                 Prior to Delivery, StorageTek shall conduct a mutually
                 agreed-upon preshipment manufacturing test at its plant on
                 each unit of Equipment.  Notwithstanding such preshipment
                 manufacturing testing, all Equipment must conform to the
                 Specifications.  StorageTek will provide IBM on a quarterly
                 basis with a complete, summarized record of inspection and
                 tests performed on each unit of Equipment during the term of
                 the Agreement.  Detailed records of inspection and tests (in
                 manual and electronic form) performed for each unit of
                 Equipment shall also be kept by StorageTek for three (3)
                 years.  Upon IBM's request, StorageTek will provide IBM with
                 access to an electronic copy of the specific test results for
                 each unit of Equipment within two (2) business days after
                 receipt of such request.

                 IBM's representative may, if it so requests and at its sole
                 expense, witness the preshipment tests carried out by
                 StorageTek, provided such request is made at least three (3)
                 days prior to the scheduled Delivery of the items being
                 tested.  Any such observation by IBM shall be subject to
                 StorageTek's reasonable safety and security rules and shall be
                 conducted to the extent feasible on a noninterference basis.

                 IBM may also conduct its own testing to the extent feasible on
                 a non- interference basis either at StorageTek's plant, its
                 own facilities or IBM's customers' facilities, at IBM's own
                 expense, to confirm that the Equipment meets the
                 Specifications.  Any testing performed at StorageTek's plant
                 shall be subject to StorageTek's reasonable safety and
                 security rules.

         9.2     ENGINEERING CHANGES

                 a.    Mandatory Engineering Changes.  If changes that may
                       affect the form, fit, function, interface, reliability
                       or serviceability of the Equipment (including
                       interchangeability with previously purchased FRUs) are
                       required in order to make the Equipment sold hereunder
                       conform to the Specifications ("Mandatory Engineering
                       Changes"), StorageTek shall first obtain IBM's approval.
                       If it is mutually agreed that the change is to be made,
                       StorageTek shall make the changes at no charge to IBM in
                       all units of Equipment which are not yet delivered to
                       IBM.  If such changes are required to make delivered
                       units of Equipment conform to those Specifications, they
                       shall be supplied in the form of mandatory field change
                       kits at no charge to IBM in accordance with the
                       procedure set forth below.

<PAGE>   29
                       IBM shall supply labor to install, subject to Section
                       9.3h,  all Mandatory Engineering Changes in delivered
                       units of Equipment.

                       Field change kits resulting from Mandatory Engineering
                       Changes described above will be administered as follows:

                       (1)    StorageTek will promptly send an engineering
                              change notice (ECN) to IBM prior to Delivery of
                              the first shipment of Equipment that contains a
                              Mandatory Engineering Change.  IBM shall issue a
                              no-charge purchase order for all mandatory field
                              change kits that IBM desires.  Such kits and any
                              Equipment returned which are covered by the
                              Mandatory ECNs shall be shipped freight prepaid
                              by StorageTek, at no charge to IBM.

                       (2)    StorageTek will ship the mandatory field change
                              kits according to the schedule that is set forth
                              in clause (4), below, and issue a no-charge
                              invoice to IBM for all parts ordered and shipped
                              as a part of the mandatory field change kits.

                       (3)    Subject to the terms of Section 15.3, IBM will
                              use reasonable efforts to see that repairable
                              parts (displaced by field change kits) from
                              Equipment are packaged separately from other
                              parts returned.  IBM will send Products to
                              StorageTek, freight prepaid, and Upgrades and
                              FRUs, freight collect.

                       (4)    For each Mandatory Engineering Change the parties
                              will agree upon an appropriate round- robin
                              process for distributing field change kits to the
                              field and securing the return of displaced FRUs
                              for rework by StorageTek.

                 b.    Emergency Engineering Changes.  Notwithstanding Section
                       9.2a, above, StorageTek may issue any engineering change
                       necessary to remedy an Equipment-down situation at a
                       customer of IBM or to make any unit of the Equipment
                       safe (an "Emergency Engineering Change") upon notice to
                       IBM but without any prior evaluation or approval by IBM;
                       provided, however, that StorageTek agrees to follow the
                       procedures as set forth in Section 9.2a in order to
                       implement a permanent solution to resolve the safety or
                       down situation that arose precipitating the need for the
                       engineering change.

                       As to any affected Equipment from time to time in IBM's
                       inventory or control, or already accepted by IBM, IBM
                       shall use reasonable efforts to promptly accomplish the
                       installation of such Emergency Engineering Change.  In
                       the event of installation of Emergency Engineering
                       Changes by IBM hereunder, StorageTek shall implement a
                       corrective action plan, including the provision of
                       information, materials, tools and parts necessary to
                       effect the installation of such Emergency Engineering
                       Changes on the affected Equipment (all without cost to
                       IBM), subject to Section 9.3h.

                 c.    Optional Engineering Changes.  In addition to Mandatory
                       Engineering Changes, it is recognized by the Parties
                       that there may be optional changes requested by either
                       IBM or StorageTek, which are not required to make the
                       units of Equipment conform to the Specifications.  The
                       cost of implementing such changes (including kits and
                       labor) on delivered Equipment shall be divided between
                       the parties as they mutually agree.  StorageTek will
                       deliver field change kits for such changes to IBM, as
                       specified in IBM's purchase order, which purchase order
                       shall be given by IBM to StorageTek within such time
                       period as the Parties shall mutually agree.

                 d.    Procedures Regarding Proposed Engineering Changes.  In
                       connection with any engineering changes proposed
                       pursuant to Section 9.2a, above, StorageTek will forward
                       to IBM, at IBM's request, a minimum of two (2) samples
                       of each such proposed engineering change, as well as the
                       details of any proposed change, to enable IBM to
                       determine whether to approve such change, including:

                       (1)    the effect of the change on the form, fit,
                              function, interface, reliability or
                              serviceability of the Equipment;

                       (2)    StorageTek's reference number for the proposed 
                              change;

                       (3)    StorageTek's  identification of the item to be
                              changed and whether any items should be returned;

                       (4)    description of and reason for the change with
                              sufficient engineering detail and applicable
                              validation data, as endorsed by StorageTek's
                              quality control process, to enable the proposal
                              to be assessed;

                       (5)    the date and, if available at the time,
                              StorageTek's serial number from which StorageTek
                              proposes to implement the change;

                       (6)    whether retroactive action is proposed and, if
                              so, the details of any necessary field action and
                              the initial availability of FRUs (on Engineering
                              Changes, StorageTek will advise IBM about the
                              effect on (a) outstanding orders for Equipment;
                              (b) units of Equipment which are at the time of
                              such proposed change in for repair or
                              replacement; and (c) the next batch of units of
                              Equipment to be delivered from StorageTek's plant
                              on which the Engineering Change should be
                              implemented);

                       (7)    intended alterations to FRUs, documentation,
                              tools and other relevant material supplied or to
                              be supplied to IBM; and

                       (8)    whether any parts will become obsolete as a 
                              result of the change.

                       Except for any Emergency Engineering Changes, StorageTek
                       is required to obtain IBM's prior written approval for
                       each Engineering Change before StorageTek's
                       implementation of the same.

                 e.    Revalidation.  Upon implementation of each engineering
                       change, StorageTek agrees to perform revalidation
                       testing at no charge to IBM to ensure that the Equipment
                       so changed meets the Specifications.

                 f.    Obsolete Upgrades and FRUs.  If StorageTek makes any
                       Mandatory, Emergency or StorageTek-initiated Engineering
                       Change which renders any Upgrades and FRUs obsolete
                       (i.e., unusable), StorageTek shall replace the obsolete
                       Upgrades and FRUs at no charge to IBM in accordance with
                       the procedures set forth in Section 9.2a, above.   No
                       returns are authorized for field change kits that are
                       requested as a result of an optional IBM- initiated
                       engineering change which renders any Upgrade or FRU
                       obsolete.

         9.3     QUALITY LEVELS

                       a.     RAS Criteria.  StorageTek shall maintain (i)
                              throughout the term of this Agreement, and (ii)
                              for a period of  **  after the date of last

                              it is not required to do so and StorageTek is
                              still providing Product Engineering Services for
                              its own distribution of Equipment or Devices);
                              the following reliability, availability and
                              service ("RAS") levels for the Products:

                       For measuring Service Calls, the calculation of a
                       Machine Month is based on the use of a 180 GB and 360 GB
                       machine configuration for Iceberg and Kodiak,
                       respectively.

                       Impact Error measurements for Kodiak will not count
                       toward any criteria until the earlier of: (i) the first
                       quarter in which  **  units of Kodiak have been
                       installed by IBM, or (ii) the second quarter of 1997,
                       provided that at least  **  units have been installed by
                       IBM as of the last day of such quarter.

                       Impact Error measurements for Iceberg will not count
                       toward any criteria until  **  units of Iceberg have
                       been installed by IBM.

                       The RAS measurements shall exclude impacts or failures
                       of Products where a microcode or engineering change is
                       available which, if installed, would have prevented the
                       impact or failure from occurring; provided, however,

                       installation pursuant to a nonemergency (i.e., generally
                       distributed) engineering change  at least three (3)
                       months prior to the date of an Impact Error or Service
                       Call.  The RAS measurements will exclude any Impact
                       Errors and Service Calls that arise from  **  concurrent
                       Drive failures in the same array, and any Service Calls
                       and Impact Errors for units of Iceberg and Kodiak
                       installed as part of the ESP, as defined in the SOW.

                       For the first ninety (90) days following the
                       availability of a Major Enhancement, IBM will exercise
                       reasonable efforts to install within 30 days engineering
                       changes that StorageTek designates as "critical."

                       Calculations of the actual Service Call Rate and Error
                       Rate will be made based on U.S. installations only.

                 b.    Error Free Installation Criteria.  StorageTek shall
                       maintain a  **  Error Free Installation rate for
                       Products and Upgrades (separately calculated) until the
                       date on which IBM no longer markets Products and
                       Upgrades.  These measurements will be calculated
                       separately for Products and Upgrades.  This rate assumes
                       that an average IBM-customer subsystem installation is
                       comprised of an Iceberg subsystem, or a Kodiak control
                       unit and one connecting storage cabinet.  If the average
                       IBM-customer installation for the Kodiak Product
                       involves more than one connecting storage cabinet, then
                       the  **  rate for Kodiak will be reduced by  **  for
                       each connecting storage cabinet in calculating such
                       average.

                 c.    Levels for Future Functions.  Features or functions
                       added after the initial shipment in volume of Iceberg
                       and Kodiak will be measured against specific
                       reliability, availability and service criteria that is
                       to be documented and addressed in each applicable
                       product development plan and related specification for
                       the future feature or function, but in any event they
                       must meet the Iceberg and Kodiak criterion as specified
                       herein.

                 d.    Guardband.  StorageTek shall not be considered to be
                       failing to meet the criterion unless the percentage by
                       which IBM's actual measurements exceeds the criterion is
                       at least higher than the Guardband percentage set forth
                       above in Section 9.3a for Service Calls or Impact
                       Errors.

                 e.    Action Plan.  If StorageTek fails to meet the Service
                       Call Rate, Impact Error Rate, or Error Free Installation
                       Rate, then StorageTek shall promptly investigate the
                       cause of the failures, and generate and provide to IBM
                       within ten (10) days a root cause failure analysis that
                       describes the cause of the failures.  StorageTek will
                       promptly develop and implement an action plan acceptable
                       to IBM to resolve such failures, which plan shall
                       include remedies for failure to

                       meet the Service Call Rate, Impact Error Rate, or Error
                       Free Installation Rate in such action plan.

                       StorageTek shall provide all support necessary to meet
                       an agreed upon repair turnaround time that is
                       established in the action plan to maintain IBM's
                       customers' satisfaction.  StorageTek's plan may include,
                       but is not limited to increased repair capacity (i.e.,
                       labor, equipment, facilities); expedited freight; and
                       providing new, repaired and/or upgraded buffer stock to
                       IBM's stocking locations, distributors and customer
                       sites.

                 f.    Price Reduction for FRU Costs.  StorageTek shall provide
                       a price reduction to IBM  **  after the date of last
                       Delivery of each type of Products in an amount that is
                       equal to  **  ("Excess FRU Cost").  The calculation of
                       this price reduction shall specifically exclude  ** .
                       The price reduction provided hereunder may  **  .   Any
                       claim to such price reduction will be deemed waived if
                       not made by IBM no later than  **   days after the  **
                       in which such Excess FRU Cost occurred.

                 g.    Reporting of FRU Consumption.  IBM will provide a
                       quarterly report to StorageTek that summarizes
                       IBM-reported fault symptom information for the
                       consumption of FRUs in repair actions that are
                       undertaken by IBM in the United States.  The summarized
                       information in this report will be adjusted by IBM to
                       exclude those items which qualify as Cost Exclusions.
                       This information is considered to be IBM confidential,
                       and StorageTek agrees to keep such information
                       confidential under the terms of the Agreement for
                       Exchange of Confidential Information between the
                       Parties.

         9.4     QUALITY ASSURANCE

                 StorageTek shall maintain at its sole cost and expense an
                 effective quality control system to maintain under continuous
                 control the entire process of design, manufacture and FRU
                 repairs, including the packaging and shipping of Equipment.
                 This system shall include checks to verify that all
                 requirements of the Specifications are satisfied.

                 StorageTek is responsible to insure that workmanship,
                 construction and other standards specified by this system
                 satisfy the requirements of the Specifications.  StorageTek's
                 quality assurance shall be applied in a manner that will
                 maintain a consistent level of quality.  StorageTek's quality
                 control procedures and instructions shall be made available to
                 StorageTek's employees, agents, contractors and
                 subcontractors, and to IBM, at the place of manufacture.

                 Upon request, IBM may conduct inspections on a
                 non-interference basis at StorageTek's manufacturing and
                 repair plants at any time during normal working hours provided
                 that, within 24 hours if an emergency situation exists or at
                 least three (3) days under non-emergency situations, prior
                 written notice is given by IBM.  StorageTek will use
                 reasonable efforts to accommodate visits on shorter notice.
                 Such inspection may, at IBM's option, include the witnessing
                 of tests and inspection of Equipment, whether completed or
                 not.  StorageTek will promptly take appropriate corrective
                 action with regard to any deficiencies found by IBM and
                 reasonably agreed to by StorageTek.

         9.5     ISO 9000 CERTIFICATION AND USE OF SUBCONTRACTORS

                 StorageTek shall maintain ISO 9000 certification, and use
                 statistical process control systems to monitor quality, for
                 its manufacturing and development processes for Equipment
                 supplied to IBM during the term of the Agreement.

                 StorageTek shall ensure that its subcontractors that are
                 involved with the manufacturing and development of Equipment
                 shall maintain ISO 9000 certification,

                 and use similar statistical process control systems to monitor
                 quality.  StorageTek shall also ensure that its suppliers who
                 provide parts, assemblies or subassemblies that are used in the
                 manufacturing and development of Equipment shall maintain ISO
                 9000 certification or use reasonable process control systems to
                 monitor quality.

                 It is the sole responsibility of StorageTek to select and
                 manage its suppliers.  StorageTek will make available to IBM,
                 upon request, a list of all suppliers that are used to supply
                 parts or components in StorageTek's manufacturing process for
                 Equipment.  StorageTek agrees to use its best efforts to
                 notify IBM of any additions or changes made in its suppliers.
                 If IBM reasonably determines that there is a supplier that may
                 be of concern to it, then StorageTek shall develop and
                 implement a mutually agreeable plan to address IBM's concerns.

                 StorageTek shall provide, upon written request by IBM, all
                 information pertaining to the measurements of quality that are
                 made for Equipment, and generated or derived from StorageTek's
                 statistical process control systems.

                 StorageTek is solely responsible for the quality of Equipment
                 supplied to IBM.  Review and approval by IBM of StorageTek's
                 or any of its subcontractor's quality process systems does not
                 relieve StorageTek of this responsibility.

                 StorageTek agrees to notify IBM of any planned significant
                 changes that may adversely affect its manufacturing processes
                 or could adversely affect the form, fit, function, quality,
                 reliability, serviceability or safety of the Equipment to be
                 supplied to IBM no later than ninety (90) days before planned
                 implementation.


10.  PRODUCT LEAD TIMES AND FORECAST

          10.1   IBM will provide a monthly build forecast to StorageTek for a
                 **  period (or a period equal to the remaining term of this
                 Agreement if less than  **  ).  The current quarter forecast
                 will be broken down by week and by Delivery location.
                 Volumes, specified in units of Product and Upgrades by
                 Delivery location,  for the quarter following the then-current
                 quarter will be established and provided to StorageTek no
                 later than  **  prior to the start of any given quarter.  At
                 such time, the forecast for the upcoming quarter will be
                 binding, subject to the quarterly volume modifications
                 referred to in Sections 10.2 and 10.3.  Except as otherwise
                 provided in the preceding sentence, volume forecasts are
                 provided as good faith estimates of IBM's anticipated
                 requirements for Products and Upgrades for the periods
                 indicated based on current market conditions and do not
                 constitute commitments to purchase any fixed quantity of
                 Products.

                 such additional units.  Any units of inventory not required
                 under this section to be purchased and delivered in the
                 then-current quarter will be applied to and delivered to
                 fulfill the next-following quarter's volume requirements
                 before any new orders for such next-following quarter are
                 fulfilled.

         10.4    CURRENT QUARTER

                 Subject to Sections 10.2 and 10.3, in order to assist
                 StorageTek in planning its manufacturing operations, IBM will
                 provide modifications to the previously submitted weekly
                 schedules in the current forecast, as follows:

                             FLEXIBILITY                   NOTICE REQUIRED
                               TARGET               (in days from anticipated
                                                           Delivery date)     
                             -----------            -------------------------
                               +/- **                        within **
                               +/- **                        within **
                               +/- **                        within **
                               +/- **                        within **
                               +/- **                        within **
                               +/- **                        beyond **

               All volume increases will be allowable per the matrix above up
               to StorageTek's maximum capacity.  StorageTek's initial maximum
               capacity is stated in the following table:

                  CAPACITY IN UNITS OF PRODUCT PER WEEK, FOR:

                                              Iceberg              Kodiak
                                              -------              ------
                               1996             **        |          **
                               1997             **        |          **
                               1998             **        |          **

                 Upon mutual agreement, StorageTek will add additional capacity
                 if IBM  increases its forecasted volumes beyond the current
                 maximum capacity with at least six months' prior written
                 notice to StorageTek.  StorageTek agrees to use reasonable
                 efforts to accommodate variations greater than those stated
                 above, including but not limited to accepting assistance from
                 IBM.

         10.5    STORAGETEK'S CAPACITY/ALLOCATION

                 a.    StorageTek expressly represents that StorageTek has, as
                       of the Effective Date of this Agreement, and will
                       maintain throughout the term of this Agreement, adequate
                       product and manufacturing capacity to fulfill in a
                       timely fashion all its existing contractual commitments
                       as well as the quantities committed to in this Agreement
                       by IBM (when taking into account Section 10.4) and any

                       commitments StorageTek subsequently enters into, without
                       allocation of production among its customers.  However,
                       if StorageTek is unable to meet its Delivery commitments
                       and must allocate its capacity, inventory, test
                       equipment, resources, use of personnel, parts,
                       components, supplier resources and capabilities, etc.,
                       that are used to produce Equipment, then StorageTek
                       agrees to:

                       (1)    act in good faith; and

                       (2)    allocate its capacity, supplier resources and
                              capabilities, inventory, test equipment,
                              resources, use of personnel, parts, components,
                              and available supply of Equipment to fill orders
                              for IBM in the following order of priorities:

                               (i)  **  ; and

                              (ii)  **

                 b.    StorageTek will allocate parts, components and materials
                       in accordance with the following priorities:

                       (1)    Code A FRUs order/requirements are filled first;
                              and

                       (2)    then a fair allocation between manufacturing
                              orders and nonemergency maintenance parts
                              order/requirements.


         11.     PURCHASE ORDERS, ALTERATIONS & RESCHEDULING

         11.1    IBM may submit purchase orders at any time; provided, however,
                 that subject to Section 11.6, any order shall be binding on
                 both Parties if such order is within the forecast range set
                 forth in Sections 10.2 and 10.3, and is submitted not less
                 than ten (10) business days before IBM's requested date of
                 Delivery.  IBM may request that StorageTek deliver in fewer
                 than ten (10) business days and StorageTek may agree to do so.

         11.2    This Agreement does not constitute a purchase order.  IBM may
                 issue purchase orders from time to time during the term of
                 this Agreement in either electronic (EDI) or written form.
                 Authorization to StorageTek to perform any work or produce any
                 Equipment under this Agreement will be through IBM purchase
                 orders only.  Alterations to the quantity, delivery date,
                 engineering level, or other items on purchase orders may be
                 made by IBM from time to time, subject to StorageTek's

                 agreement.  Purchase orders will be considered noncancelable
                 within ten (10) days of the scheduled Delivery date.

         11.3    IBM shall submit its purchase orders to StorageTek at the
                 address set forth in the Notices section of this Agreement.
                 IBM's purchase orders will include:

                 a.    IBM's part, model or feature numbers, configuration and
                       description of Equipment;

                 b.    quantity required;

                 c.    unit or item price and total order price;

                 d.    required delivery date(s);

                 e.    delivery instructions (including a carrier who will
                       accept delivery at StorageTek's address); and

                 f.    reference to this Agreement.

                 Unless otherwise specifically agreed to in writing, additional
                 terms and conditions on IBM's purchase orders or on
                 StorageTek's acknowledgment, whether in conflict with this
                 Agreement or not, are superseded hereby and are of no force
                 and effect.

         11.4    StorageTek agrees to accept conforming IBM purchase orders and
                 to manufacture, supply and Deliver Equipment in accordance
                 with the terms and conditions of this Agreement.  StorageTek
                 agrees to provide written acknowledgment of IBM's purchase
                 orders within two (2) days, for volumes within IBM's forecast,
                 or within five (5) days, for volumes  in excess of IBM's
                 forecast, as measured from StorageTek's actual receipt of the
                 purchase order (without regard to the Notices section of this
                 agreement, except for EDI) which purchase order may be made
                 verbally and/or in advance of StorageTek's receipt of a hard
                 copy confirming such order.  If StorageTek's acknowledgment is
                 not received by IBM within the two (2) or five (5) day period,
                 as described above, from the date of receipt of the purchase
                 order from IBM, then the purchase order, including the
                 requested delivery date(s) will be deemed to be accepted by
                 StorageTek.  StorageTek may not reject any IBM purchase order
                 that conforms to the requirements of this Agreement and covers
                 quantities forecasted by IBM, as described in Section 10.

         11.5    Orders for FRUs needed on a "Code A" basis (i.e.,
                 emergency-customer down) will be shipped by StorageTek within
                 twenty-four (24) hours at a price not to exceed the lesser of
                 **  of the price in Exhibit 5 or such price plus  ** , with
                 IBM designating

                 the carrier and being responsible for freight and insurance
                 costs.  However, IBM will not pay any premium (i.e. pay only
                 100%) for Code A FRUs necessitated because StorageTek has
                 failed to deliver nonemergency FRU orders within the lead
                 times set forth in Exhibit 5.

         11.6    IBM may cancel purchase order(s) or any portions thereof for
                 any reason by notifying StorageTek in writing at least ten
                 (10) days prior to the scheduled Delivery date.  Cancellation
                 will be effective upon StorageTek's receipt of the wri
