                                  OEM AGREEMENT

         This agreement is made and entered into as of December 18, 1997, 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." This Agreement amends, supersedes and replaces in
its entirety the OEM agreement dated June 7, 1996, as amended, between the
Parties, and will have prospective force and effect. However, this Agreement
shall not affect IBM's obligation to pay for any Equipment ordered by IBM under
a purchase order and accepted by StorageTek prior to the date of the Agreement's
execution by authorized representatives of the Parties.

BACKGROUND

         StorageTek manufactures and sells, among other things, certain
Equipment as more fully described below. IBM wishes to purchase such Equipment
from StorageTek on an Original Equipment Manufacturer (OEM) basis 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 the prices set forth
herein if IBM will purchase, 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,

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. On receipt of IBM's written
         request, StorageTek agrees if such [**], it will [**]. StorageTek 
         agrees to [**] if IBM [**], and if such [**], and such [**].

         7.5      [**] PRICE

                  Notwithstanding any other provisions in this Agreement, in no
                  event will any price charged by StorageTek to IBM exceed "[**]
                  Price," as defined below:

                  a.       The prices, [**] offered by StorageTek to IBM for
                           [**] ordered by IBM under [**] placed on or before
                           [**] under this Agreement shall be [**]. The prices,
                           [**] offered by StorageTek to IBM for [**] by IBM
                           under [**] and/or [**] under this Agreement shall be
                           [**] after [**] to [**].

                  b.       If StorageTek offers, on or before [**], to any [**]
                           purchasing [**] at the [**] more [**] than are
                           offered to IBM for [**] hereunder; or if StorageTek
                           offers to [**] [**] for [**] to [**] on or [**]
                           and/or [**] than are offered to [**]; then StorageTek
                           agrees to notify IBM in writing within [**] of making
                           such offer, and StorageTek agrees to [**] to IBM the
                           [**] prices, [**].

                  c.       Notwithstanding anything to the contrary, under no
                           circumstances shall StorageTek be [**] to offer to
                           IBM any prices [**] for [**] that StorageTek has
                           offered to a[**] from StorageTek.

                           StorageTek grants IBM Audit Rights for purposes of
                  confirming that IBM is receiving [**] Prices. If the auditor
                  determines that IBM did not receive such prices, then in
                  addition to the remedies provided above, StorageTek will
                  reimburse IBM its costs for the audit. Audits will not exceed
                  two in any 12-month period.

         7.6      SNAPSHOT FEATURE

                  IBM will license the Snapshot Feature as set forth in the
                  Description of Licensed Works for the license fees set forth
                  in Attachment 2 to Exhibit 1 hereto.

                  Prices charged by StorageTek to IBM for new FRUs will be [**]
                  of such FRUs and the multiples set forth in Section 7.7a,
                  below ("New FRU Cost"). For the purpose of this Section and
                  Section 15.4, cost shall be determined by using [**]. The
                  standard cost will be reviewed [**], and any differences in
                  cost will be adjusted in the following period. Compliance with
                  this section shall be subject to IBM's Audit Rights.

                  a.       Multiples for New FRUs.

                           (1) During the term of this Agreement the multiple 
                  is [**].

                           (2) After the termination of this Agreement the
                  multiple is [**].

                  b.       FRU Rework. Prices for FRUs returned by IBM will be
                           determined in accordance with Section 15.4.

         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.

                  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 available funds.

8.       IBM SALES TO STORAGETEK

         IBM will offer for sale to StorageTek the [**] IBM disk drives that are
         used in the [**] and [**] and sold to IBM under the Agreement, or
         similar IBM disk drive replacements therefor, for use in [**] (whether
         or not considered to be a [**] under this Agreement) and the [**] [**]
         throughout the term that this Agreement is in effect, for a [**]
         thereafter, and [**] [**] to [**].

         Notwithstanding anything to the contrary, in the event of a termination
         of this Agreement pursuant to Sections 21, 23(e), 23.7 or 23.8 , for a
         period of [**] after such termination or [**], whichever occurs first,
         IBM will offer for sale to StorageTek the same IBM disk drives that are
         used in the [**] and [**] and sold to IBM under the Agreement, or
         similar IBM disk drive replacements therefor, for use in [**] (whether
         or not considered to be a [**] under this Agreement) and the [**].

         Upon [**] notice, IBM will notify StorageTek of its planned withdrawal
         from general availability of the IBM disk drives that StorageTek
         chooses to purchase. If a similar IBM disk drive replacement therefor
         is not available, then subject to [**] and prior written notice from
         StorageTek no later than [**] after StorageTek's receipt of IBM's
         notice, IBM will allow StorageTek, at its option, to 


                                       13
<PAGE>   20


         either (i) [**] IBM disk drives before their planned withdrawal date;
         or (ii) [**] contained in the IBM withdrawal notification letter.

         IBM disk drives will be made available for sale by IBM to StorageTek
         solely in accordance with the terms of its existing [**] and this
         Section 8 of the Agreement.

         Throughout the term of this Agreement and for a period [**], and in the
         event of a termination of this Agreement pursuant to Sections 21,
         23(e), 23.7 or 23.8, [**] or through [**], whichever occurs first, the
         price to be charged to StorageTek for IBM disk drives to be sold during
         a [**] shall be [**]. Pricing for StorageTek's purchase of IBM disk
         drives during a [**] will be based on [**] disk drives for such [**]
         under IBM's terms and conditions set forth in [**] and this Section 8.

         StorageTek will integrate or incorporate IBM disk drives into [**]
         (whether or not considered to be a [**] under this Agreement) and the
         [**] that are to be sold [**]. StorageTek will be deemed to have
         accepted IBM disk drives [**] after StorageTek receives them unless
         written notice of rejection therefor is sent to IBM during such period
         by StorageTek. IBM will inform StorageTek of changes to the product
         specifications of IBM disk drives sold to StorageTek under [**] and
         this Section 8 that may affect form, fit or function within [**] prior
         to delivery of such IBM disk drives to StorageTek; provided, however,
         that IBM may make any changes to the [**] of IBM disk drives without
         prior notification if such changes are made to [**] issue, or to comply
         with governmental regulations or laws. For all claims that are not
         excluded by Section 10(a), or subject to other terms, of [**] and this
         Section 8, IBM's liability for [**] shall be [**] or [**].

         Upon request, IBM will offer StorageTek up to a [**] warranty on the
         IBM disk drives it wishes to purchase; provided, however, that IBM [**]
         offers the same period of warranty on such IBM disk drives to other
         [**] . IBM may [**] the pricing it provides to StorageTek for
         differences in warranty terms. Such pricing will, however, be
         consistent with the pricing that is established [**] for the [**] who
         receive the same length of warranty on IBM disk drives and the [**] for
         their existing commitments to purchase comparable quantities over such
         [**] under other standard [**] terms and conditions.

         If StorageTek is unable to obtain IBM [**] for use in [**] from [**],
         through [**], then StorageTek shall promptly notify IBM in writing and
         upon receipt of such written notification and subject to availability,
         IBM will make reasonable efforts to [**].

         The terms of this Section 8 will survive the [**] or [**] of this
         Agreement. In addition, in the event of an inconsistency between the
         terms of this Section 8 and the terms of the [**], the terms of this
         Section 8 shall prevail.

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.

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

                           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;

                                    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 [**], and (ii) for a period of [**] after
                           the date of last Delivery of each type of Product
                           (provided IBM pays for the Product Engineering
                           Services unless 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

                           Impact Error measurements for Kodiak will not count
                           toward any criteria until the first quarter in which
                           [**] units of Kodiak 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, that such microcode or engineering
                           change was made available by StorageTek for
                           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
                           [**] or more 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
                           Impact Error Rate will be made based on U.S.
                           installations only.

                           IBM will notify StorageTek in writing of an Impact
                           Error within [**] after an Impact Error occurs. In
                           order to assist IBM in this notification process,
                           StorageTek will provide IBM with [**] to StorageTek's
                           [**]. IBM acknowledges that the [**], and IBM agrees
                           to keep such information confidential and in
                           accordance with the AECI between the Parties. If
                           detailed information about an Impact Error is needed,
                           then StorageTek will notify IBM in writing of its
                           need to obtain such information [**] after IBM
                           reports an Impact Error to StorageTek. Upon receipt
                           of StorageTek's written request for detailed
                           information, IBM will obtain and supply to StorageTek
                           the requested information, if and as available, [**]
                           after the receipt of StorageTek's written request.
                           StorageTek will analyze the available information and
                           determine whether an Impact Error occurred.
                           StorageTek will then communicate its decision in
                           writing as to whether it believes an Impact Error has
                           or has not occurred to IBM. If StorageTek believes
                           that an Impact Error has not occurred, then it will
                           provide in writing to IBM, [**] after StorageTek's
                           receipt of the available information, a reason for
                           StorageTek's belief that an Impact Error has not
                           occurred and shall [**]. If IBM fails to notify
                           StorageTek in writing of an Impact Error or to
                           provide written information that is available, within
                           the established time periods, then the [**]. If
                           StorageTek fails to request information in writing
                           from IBM, to provide in writing to IBM a reason for
                           its belief that an Impact Error has not occurred, or
                           to [**] in writing to the [**], within the
                           established periods, then the [**].

                  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 [**] StorageTek. 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


                                       21
<PAGE>   28


                           such information confidential under the terms of the
                           Agreement for Exchange of Confidential Information
                           between the Parties.

                  h.       Credit for Labor Costs. The target for labor required
                           for repair actions (including [**] and those repair
                           actions related to [**], but excluding labor required
                           for [**] is [**] for each [**] during a Machine
                           Month. StorageTek shall provide a credit to IBM on a
                           [**] basis up through [**] after the date of last
                           Delivery of Product, upon StorageTek's receipt of
                           appropriate supporting documentation, for average
                           labor costs per Machine Month incurred by IBM in
                           connection with repair actions that are in excess of
                           [**] of that [**] target ("Excess Labor Cost"). The
                           amount of this credit will be calculated by
                           multiplying the number of hours in excess of [**] of
                           that [**] target by a rate of [**] per hour. In the
                           event that IBM incurs labor costs in excess of [**]
                           of that [**] target and the Parties determine that
                           the incurrence of [**], then a [**] action will be
                           developed and implemented. This plan shall include
                           [**]. The calculation of Excess Labor Cost will be
                           based on [**] and [**]. The credit provided hereunder
                           may [**] be used by [**], first, by [**] against any
                           [**] during the [**]; second, against [**]; or third,
                           [**] after [**]. Any claim to such credit will be
                           deemed waived if not made by IBM no later than [**]
                           days after the [**] in which such Excess Labor Cost
                           occurred.

                  i.       Attainment. The RAS criteria will be separately
                           calculated and applied to Iceberg and Kodiak. If
                           StorageTek fails to meet the established RAS criteria
                           for Service Calls or Impact Error rates set forth in
                           Section 9.3a for Iceberg or Kodiak in any calendar
                           quarter (after taking into consideration the
                           applicable Guardbands), then StorageTek shall be
                           given until the end of the immediately succeeding
                           quarter to implement the action plan described in
                           Section 9.3e, above.

                           If the RAS criteria is missed again during an
                           immediately succeeding [**], then an amount equal to
                           [**] by which the RAS experience for such period was
                           more than the target RAS criterion set forth in
                           Section 9.3a., above, for a [**] with [**] shall be
                           [**] and [**] purchases and any [**] obtained under
                           this Agreement [**] such [**] to determine the [**]
                           of [**] to be acquired during [**]. In the event that
                           this [**] results in a [**] of [**] and [**]
                           purchases and any [**] obtained under this Agreement
                           during [**] that is [**], then IBM shall [**] and
                           [**] in an [**] Section 9.3a., above, for each [**]
                           toward [**] over [**].

                           If the Parties agree on a [**] for [**] purchases and
                           the RAS criteria is missed again during an
                           immediately succeeding [**], then IBM [**] and/or
                           [**]. The amount of [**] that IBM 


                                       22
<PAGE>   29


                           will obtain will be calculated by [**] set forth in
                           Section 9.3a, above, for a miss associated with [**].
                           However, if IBM reaches [**] whereby [**], or if [**]
                           by the Parties, then IBM will [**] and [**] that is
                           equal to the [**] and [**] [**] (i) the [**]; and
                           (ii) [**].

                           The Parties agree that [**], which will be [**] by
                           the Parties, shall be available with regard to a RAS
                           criteria miss [**]. Notwithstanding anything to the
                           contrary, no [**] or [**] shall be given to IBM with
                           respect to any RAS criteria miss for [**] until [**];
                           or for [**] during [**] and any [**].

                           The [**] that IBM is [**] will be calculated
                           separately for "Service Calls" and "Impact Errors."
                           Such separate amounts will be aggregated to determine
                           the amount of the credit that IBM is entitled to
                           receive and [**] of [**] and [**].

         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 


                                       23

                  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 


                                       24

                  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.

         10.2     StorageTek agrees to supply, and IBM agrees to issue purchase
                  orders for and take Delivery of, during any current quarter,
                  and to pay for in accordance with Section 7 above, [**] of the
                  [**] units forecasted for the [**] in the binding forecast
                  provided by IBM to StorageTek pursuant to Section 10.1. Unless
                  IBM [**] in the [**] by issuing purchase orders therefor,
                  StorageTek agrees to use such [**] to satisfy the next
                  quarter's orders. Any units 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 forecast before any new orders for such
                  next-following quarter are fulfilled.

         10.3     After IBM provides a binding forecast to StorageTek pursuant
                  to Section 10.1, IBM may also require StorageTek to Deliver
                  during the current quarter by issuing purchase orders for [**]
                  and [**], for which IBM shall pay in accordance with Section
                  7, above, up to [**] of the units forecasted as of date the
                  volumes became binding as provided in Section 10.1.

         10.4     CURRENT QUARTER

                  Subject to Sections 10.2 and 10.3, solely to assist StorageTek
                  in planning its manufacturing operations for units that are
                  forecasted for the current quarter, IBM will provide
                  modifications to the previously submitted weekly schedules in
                  the current forecast, as follows:

</TABLE>

                  StorageTek shall [**] in accordance with the binding forecast
                  unless IBM issues purchase orders for [**]. Any modifications
                  that IBM makes to the [**] shall not affect IBM's obligation
                  to purchase [**] that were originally forecasted for the [**]
                  unless IBM submits binding purchase orders for additional
                  units of [**] and [**]. In addition, under no circumstances
                  shall StorageTek be required to Deliver to IBM per the matrix
                  above more than [**] of [**] or [**] during the [**] , and the
                  [**].

         10.5     STORAGETEK'S ALLOCATION

                  a.       If StorageTek is unable to meet its Delivery
                           commitments and must allocate its capacity,
                           inventory, test equipment, resources, use 


                                       25

                           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 [**],
                                    among IBM and other customers based upon the
                                    delivery dates requested in purchase orders
                                    received by StorageTek from IBM and other
                                    customers.

                           For a given date, StorageTek will allocate production
                           for shipment to IBM and other customers on a [**]
                           basis.

                  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,
                  which delivery shall hereafter be referred to as "Expedite
                  Shipment."

         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:


                                       26
<PAGE>   33


                  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     Except for any [**] issued by IBM to StorageTek for [**] to be
                  Delivered after the [**] this Agreement, IBM may cancel
                  purchase order(s) or any portions thereof for any reason by
                  notifying StorageTek in writing at least 


                                       27
<PAGE>   34

                  ten (10) days prior to the scheduled Delivery date.
                  Cancellation will be effective upon StorageTek's receipt of
                  the written cancellation notice from IBM. StorageTek will
                  immediately cease building such units for the affected
                  purchase order(s) in accordance with the cancellation notice.
                  IBM will have no liability for canceled purchase orders other
                  than as set forth in Section 10.2.

         11.7     If for any reason StorageTek is unable to Deliver as required
                  by accepted IBM purchase order(s), and fails to correct such
                  inability within [**] of such failure, IBM will have the right
                  to cancel such purchase order(s) or portions thereof by
                  notifying StorageTek in writing. If IBM cancels purchase
                  orders under this Section 11.7, IBM's only obligation will be
                  to pay for Products or Upgrades already Delivered at the time
                  of IBM's cancellation notice.

         11.8     Due to ongoing and unpredictable market conditions, StorageTek
                  agrees to permit IBM, upon written notice to StorageTek, to
                  require StorageTek to reconfigure units of Products and
                  Upgrades as follows:

                  a.       Configuration changes that do not change a unit model
                           number may be made without additional cost until [**]
                           before scheduled Delivery; and

                  b.       Any other configuration changes may be made at any
                           time (including Product and Upgrades that require
                           reconfiguration after Delivery) and such
                           configuration changes will be [**]. StorageTek and
                           IBM will agree in advance on a schedule of lead times
                           and costs that will apply to such configurations.

         11.9     Subject to Section 10, IBM may reschedule purchase order(s) or
                  any portions thereof for any reason by notifying StorageTek in
                  writing at least [**] prior to the Delivery Date specified on
                  the purchase order(s).

         11.10    For the last quarter of this Agreement, the purchase orders
                  submitted by IBM to StorageTek shall be noncancelable unless
                  StorageTek is manufacturing Devices.

         11.11    Except as otherwise provided in [**] Products and Upgrades 
                  that are supplied to IBM hereunder will consist of new parts
                  and components. FRUs that IBM returns will be reworked by
                  StorageTek to an equivalent-to-new reliability level. Such
                  reworked FRUs will not be used in any new Products or Upgrades
                  Delivered to IBM hereunder, but may instead be returned to IBM
                  as reworked FRUs.

12.      CONSIGNMENT

         12.1     IBM will consign certain disk drives ("Drives") to StorageTek
                  for use in Equipment. Except as otherwise provided in [**] of
                  the IDA, Drives supplied by IBM to StorageTek shall only be
                  used by StorageTek to build Equipment for IBM and shall remain
                  the property of IBM. This Section 12 shall not apply to [**]
                  StorageTek pursuant to the terms of Section 8 of this
                  Agreement.

         12.2     StorageTek agrees to adhere to the terms and conditions of the
                  IBM Consignment Agreement, attached hereto as Exhibit 4,
                  provided, however, that the terms of this Section 12 prevail
                  over those of Exhibit 4.

         12.3     IBM agrees to consign Drives to StorageTek in accordance with
                  a mutually agreed Profile based on at least a five-day buffer
                  ahead of StorageTek's build cycle, and including a yield
                  factor based upon the previous quarter's experience and
                  calculated using a mutually agreed formula. Any Drives, or
                  other IBM-supplied parts and components, that are not used by
                  StorageTek due to integration fall-out will be returned to IBM
                  within ten (10) days after such fall-out.

         12.4     If IBM fails to provide consigned Drives to StorageTek in
                  accordance with Section 12.3, and StorageTek's manufacturing
                  line is down such that StorageTek cannot meet its Delivery
                  dates to IBM, then StorageTek will agree, per Section 10.2, to
                  hold up to [**], as the case may be, of such undelivered and
                  forecasted Products and Upgrades, without Drives, in inventory
                  for up to [**]. If the amount of such Products and Upgrades
                  held in inventory exceeds [**] of the forecasted volumes then
                  StorageTek will notify IBM, and IBM will [**].

         12.5     If IBM Drives are not available for an extended period of
                  time, IBM may request assistance from StorageTek in securing
                  drives from other drive manufacturers in lieu of using IBM
                  Drives. StorageTek agrees, on a best effort basis, to assist
                  in securing the most cost effective, high quality alternative,
                  and with the agreement of IBM, to take the steps necessary to
                  integrate such drives into the Product. In such event, the
                  parties will agree in advance on an equitable division of
                  StorageTek's cost of securing, qualifying and integrating such
                  drives, including any cost relating to inventory or required
                  firm purchase commitments even if such substitution is only
                  temporary in nature.

         12.6     StorageTek agrees to return to IBM freight collect any Drives
                  in StorageTek's inventory, within five (5) days of receipt of
                  IBM's written (or EDI) request.

13.      DELIVERY

         13.1     ON-TIME DELIVERY

                  a.       StorageTek shall use its best efforts to ensure that
                           every scheduled Delivery date is met. StorageTek must
                           notify IBM in advance if a scheduled Delivery date
                           will not be met. StorageTek will make every
                           reasonable effort at its expense to ensure the
                           earliest possible Delivery date and quantities for
                           late Equipment, including, but not limited to,
                           overtime and expedite charges. "On schedule" means
                           [**]. Unless delay is caused by IBM's delay in its
                           supply of Drives or IBM-supplied parts and
                           components, StorageTek will arrange for premium
                           transportation and pay, at StorageTek's sole cost and
                           expense, for the difference between normal
                           transportation and such premium transportation,
                           including, but not limited to, air transportation and
                           expedited freight charges. StorageTek also agrees to
                           provide, at IBM's request, an action plan to correct
                           late shipments and to resolve any Delivery problems.

                  b.       If, during any [**] period, StorageTek fails, on a
                           one-time basis only, to Deliver more than [**], but
                           not more than [**], of the units of [**] and [**]
                           that are scheduled for Delivery in a calendar month
                           by their scheduled Delivery dates, then StorageTek
                           shall be required to expedite shipment of such units
                           in accordance with Section 13.1. If more than [**] of
                           such units of [**] and [**] are Delivered late in
                           [**], then an amount equal to [**] the number of [**]
                           that were [**] [**] in excess of [**] shall be added
                           to [**] and [**] purchases and credits obtained under
                           this Agreement during [**] (i.e., as though IBM had
                           already purchased such [**]) to determine the [**] to
                           be [**] during [**] . In the event that this [**]
                           results in a combined volume of [**] and [**]
                           purchases and credits obtained under this Agreement
                           during [**] that is [**], then IBM shall receive a
                           [**] and [**] in an amount equal to [**] under this
                           Section 13, On-time Delivery; provided, however, that
                           under no circumstances shall IBM receive any [**]
                           hereunder after the combined total of [**] and [**]
                           purchases and credits [**] [**] obtained under this
                           Agreement exceeds [**] during the [**].

                  c.       If StorageTek fails to Deliver more than [**] of the
                           units of [**] and [**] that are scheduled for
                           Delivery by their scheduled Delivery dates in the
                           [**] , and except for units subject to the [**]
                           provision defined in 13.1b, above, then an amount
                           equal to [**] the number of [**] that were [**] shall
                           be [**] and [**] obtained under this Agreement during
                           [**] to determine [**] of future units of [**] to be
                           acquired during [**]. In the event that this [**]
                           results in a combined volume of [**] and [**]
                           purchases and credits obtained under this Agreement
                           during [**] that is [**], then IBM shall [**] to be
                           [**] in an amount equal to [**] under this Section
                           13, On-time Delivery; provided, however, that under
                           no circumstances shall IBM receive any [**] hereunder
                           after the combined total of


                                       30
<PAGE>   37

                           [**] and [**] purchases and credits [**] obtained
                           under this Agreement exceeds [**] during the [**].

                  d.       If, in the [**] following any [**] in which a [**]
                           was made under this Section 13.1, StorageTek fails to
                           Deliver more than [**] of the units of [**] and [**]
                           that are scheduled for Delivery by their scheduled
                           Delivery dates, then an amount equal to [**] the
                           number of [**] shall be [**] to [**] and [**]
                           purchases and credits obtained under this Agreement
                           during [**] [**] to determine [**] of future units of
                           [**] to be acquired during [**] . In the event that
                           this [**] results in a combined volume of [**] and
                           [**] purchases and credits obtained under this
                           Agreement during [**] that is [**], then IBM shall
                           receive a [**] and [**] in an amount equal to [**]
                           under this Section 13, On-time Delivery; provided,
                           however, that under no circumstances shall IBM
                           receive any [**] hereunder after the combined total
                           of [**] and [**] purchases and credits in [**]
                           obtained under this Agreement [**] during the [**].

                  e.       If, in the next following month, StorageTek fails to
                           Deliver more than [**] of the units of [**] and [**]
                           that are scheduled for Delivery by their scheduled
                           Delivery dates, then an amount equal to [**] the
                           number of [**] that were [**] by StorageTek shall be
                           [**] and [**] purchases and credits obtained under
                           this Agreement during [**] to determine [**] of
                           future units of [**] to be acquired during [**]. In
                           the event that this addition results in a combined
                           volume of [**] and [**] purchases and credits
                           obtained under this Agreement during [**] that is
                           [**] , then IBM shall receive a [**] and [**] in an
                           amount equal to [**] under this Section 13, On-time
                           Delivery; provided, however, that under no
                           circumstances shall IBM receive any [**] hereunder
                           after the combined total of [**] and [**] purchases
                           and credits in [**] obtained under this Agreement
                           [**] during the [**].

                  f.       If, in the next following month, and for each
                           additional consecutive month, StorageTek fails to
                           Deliver more than [**] of the units of [**] and [**]
                           that are scheduled for Delivery by their scheduled
                           Delivery dates, then an amount equal to [**] the
                           number of [**] that were [**] by StorageTek shall be
                           [**] and [**] purchases and credits obtained under
                           this Agreement during [**] to determine [**] of
                           future units of [**] to be acquired during [**] . In
                           the event that this addition results in a combined
                           volume of [**] and [**] purchases and credits
                           obtained under this Agreement during 1998 that is
                           [**], then IBM shall receive a [**] and [**] in an
                           amount equal to [**] under this Section 13, On-time
                           Delivery; provided, however, that under no
                           circumstances shall IBM receive any [**] hereunder
