end-users.

9.6      Unless otherwise agreed, all prices quoted are payable in U.S. funds
and shall be exclusive of taxes (including without limitation any added value,
use, sales, or similar tax).  Unless MCI has provided an approved tax exemption

shall hold Systems Provider harmless therefrom, provided that if Systems
Provider at its sole discretion, chooses to make any such payment, MCI shall
reimburse Systems Provider in full.  All transactions pursuant to this
Agreement shall be considered taxable unless MCI provides Systems Provider with
appropriate verification of exemption as stated herein in this Article.  All
prices quoted shall likewise be exclusive of any import duties imposed by the
country of final destination upon shipments from Systems Provider to MCI.

9.7      Systems Provider represents and warrants that the prices set forth in
Exhibit B shall be no higher than the current Systems Provider price to any
other customer for the same quantity of Products purchased over a similar
period of time and under like conditions.  Systems Provider further agrees that
in the event prices for the same quantity for such Products under like
conditions are lowered, Systems Provider shall notify MCI in writing of the new
prices and Exhibit B shall be adjusted by written amendment.

9.8.     Systems Provider may sell to MCI at prices lower than those cited
herein on a case-by-case basis, and such sales shall not have the effect of
lowering the prices generally offered under this Agreement.  Systems Provider
shall notify MCI in writing and the prices for special cases shall be adjusted
by written amendment to this Agreement.

9.9      Each party shall prepare and maintain, at its expense, complete and
accurate books and records documenting financial transactions.  Under this
Agreement such books and records shall be maintained for a period of three (3)
years after the date of termination or expiration of this agreement.

9.10     During the initial term and any subsequent renewal periods, and for a
period of *** years after the termination or expiration of this Agreement, each
party shall have the right, at its expense and upon reasonable notice to the
other party, to examine or have examined by its authorized representatives the

documentation and are subject to acceptance and acknowledgment by Systems
Provider.  Systems Provider acknowledges that any Purchase Orders received from
MCI shall be null and void unless issued by an MCI Procurement Department
representative.  During the term of this Agreement, except where such
provisions are expressly agreed to, the terms and conditions of this Agreement
shall supersede all different or conflicting terms on MCI's Purchase Orders or
on Systems Provider's order acknowledgment forms.  Systems Provider will
provide MCI with notice of acceptance or rejection of purchase order within ***
business days of receipt of the purchase order by Systems Provider. At the time
of acceptance of the order Systems Provider shall also accept MCI's requested

18.      TERM AND TERMINATION

18.1     This Agreement shall commence on the Effective Date and shall continue
for three (3) years from the Effective Date.  It shall be renewed automatically
for successive one-(1) year terms unless either party gives written notice of
termination to the other sixty-(60) days prior to expiration, or unless
terminated pursuant to Section 18.2 or 18.5 of this Agreement.

18.2     Subject to Section 18.3, either party shall have the right to
terminate this Agreement as follows:

         (a)     Upon the breach by the other party of any material term of
                 this Agreement;





                                     - 15 -
<PAGE>   16

         (b)     Upon the issuance of an injunction by a court or regulatory
                 agency of competent jurisdiction enjoining continued
                 performance by the parties, under this Agreement;

         (c)     Upon the filing of voluntary or involuntary bankruptcy by the
                 other party or the declaration of insolvency, however
                 evidenced, by the other party which is not dismissed within
                 thirty (30) days after the date of filing;

         (d)     Upon change of control of the other party or of any division
                 or subsidiary of the other party that is relevant to
                 performance under this Agreement if such change can be
                 reasonably interpreted by the terminating party as
                 substantially detrimental to the relationship between the two
                 parties.

18.3     If a party wishes to terminate this Agreement under Section 18.2
above, such party shall give the other party written notice of its intention to
terminate under this section 18, specifying in reasonable detail the reason(s)

cure the reason thirty (30) days after such notice, this Agreement shall, at
the option of the party giving notice, terminate.

18.4     If a party terminates this Agreement under Section 18.2 above, at
MCI's request Systems Provider will fulfill all orders accepted under Section
10.1 prior to the date of the receipt of notice given in Section 18.3.  Systems
Provider shall also refund to MCI any unused portions of maintenance and
support Services fees paid by MCI associated with any returned Products.

18.5     Notwithstanding anything to the contrary contained herein, either
party may terminate this Agreement at any time for its convenience.

19.      CONFIDENTIALITY

19.1     Each party agrees to treat all information and materials received from
the other party that are labeled "Confidential" or "Proprietary" as
confidential information ("Confidential Information") of the other party. Each
party further agrees to use at least the same degree of care to avoid
disclosure or dissemination of the other party's Confidential Information as it
uses to protect its own confidential materials, but in any event, at least a
reasonable degree of care.  Neither party shall use the Confidential
Information of the other party for its own benefit or for the benefit of any
third party, except as expressly permitted in this Agreement.

19.2     Each party agrees to advise all of its employees, agents,
subcontractors or consultants that may have access to or otherwise receive the
Confidential Information of the other party of all obligations pertaining to
the protection of the Confidential Information of the other party under this
Agreement.

19.3     Neither party shall disclose Confidential Information of the other
party to any third party (other than independent contractors having a
"need-to-know") without the other party's prior written consent; provided,
however, that a party shall not be liable for disclosure of information
designated as "Confidential" or "Proprietary" by the other party if the same:

         (a)     is in the public domain at the time of disclosure; or

         (b)     becomes known to the other party from a third-party source
                 under no obligation to maintain confidentiality; or

         (c)     becomes publicly available through no fault or failure to act
                 by the receiving party in breach of this Agreement; or

         (d)     is already known by the receiving party when received, or is
                 independently





                                     - 16 -
<PAGE>   17
                 developed by the receiving party without reference to the
                 information provided by the other party, as established by
                 documentary evidence; or

         (e)     is required by a court or other governmental authority to be
                 disclosed (provided that the receiving party has used
                 reasonable efforts to make such disclosure subject to a
                 protective order or confidentiality agreement).

19.4     If, in order to fulfill the purposes of this Agreement, it is
necessary for the party receiving Confidential Information of the other party
to copy the same, in whole or in part, the receiving party may do so, but
solely for the purpose of enabling such party to perform under this Agreement.

19.5     Upon achieving the purpose(s) intended, or in the event of the earlier
termination of this Agreement, each party shall immediately return and/or
destroy all materials containing Confidential Information of the other party.
Each party shall further certify in writing to the other party that all copies
or partial copies of material containing Confidential Information of the other
party have been returned and/or destroyed.

20.      TRADEMARKS, TRADE NAMES AND MARKETING

20.1     Except for any announcement intended solely for internal distribution
(i.e., to any party under this Agreement) or any disclosure required in the
opinion of discloser's legal advisors by legal, accounting, or regulatory
requirements, all media releases, public announcements, or public disclosures
for general distribution (including, but not limited to, promotional or
marketing material) by any party under this Agreement, or by any of their
employees or agents relating to this Agreement or its subject matter, other
than general statements that a contractual relationship exists between the
parties, shall be coordinated with and approved in writing by the other party
prior to the release thereof.

20.2     In the advertising and sale or distribution of the Products, MCI may
use Systems Provider's regular logos, corporate name, trade names and
trademarks (the "Trademarks").  For this purpose, Systems Provider grants MCI a
non-exclusive, royalty-free, limited license to use the Trademarks, provided
that MCI displays the symbol "TM" adjacent to each use of a Trademark the first
time a Trademark is used, or displays such other symbols and notices as may be
prescribed by Systems Provider.  Systems Provider will provide MCI with a list
of its Trademarks and with a copy of its graphics standards manual, which shall
define the appropriate usage of such Trademarks.

20.3     MCI acknowledges that it has been advised by Systems Provider that
Systems Provider is the exclusive owner of the Trademarks.  The use of the
Trademarks by MCI does not convey to MCI any right, title or interest in or to
the Trademarks.  MCI may not register any Trademark in any jurisdiction unless
such registration is made on behalf and for the benefit of Systems Provider and
is expressly approved by Systems Provider in advance and writing.

20.4     MCI will not make or permit alteration of the goods or removal or
modification of any tags, proprietary notices, labels, or any other identifying
marks placed by Systems Provider or its agents on its Products or associated
literature.

20.5     MCI agrees not to use the Systems Provider corporate name, trademarks,
trade names and copyright legends with respect to any Products or materials not
provided by Systems Provider, or in the way which might result in confusion as
to Systems Provider and MCI being separate and distinct entities.

20.6     Notwithstanding Section 20.1, MCI may describe its relationship with
Systems Provider in MCI's proposals and statements of qualification issued for
specific MCI prospects or clients without obtaining Systems Provider's approval
and without submitting such description to Systems Provider.

20.7     Systems Provider agrees not to use MCI's corporate name, trademarks,
trade names, copyright legends or





                                     - 17 -

other intellectual property without the prior written permission of MCI.


INSURANCE AND INDEMNITY

21.1     Insurance.  During the term of this Agreement, the Systems Provider
shall maintain insurance, the kinds and in the amounts specified with insurers
of recognized responsibility, licensed to do business in the State(s) where the
work is being performed and having either: an A.M. best rating of A8, a
Standard & Poor's rating of AA, or Moody 's rating of Aa2.  If any work
provided for or to be performed under this Agreement is subcontracted, the
Systems Provider shall require the subcontractor to maintain and furnish
insurance equivalent to that required of Systems Provider.

         (a)     Comprehensive or Commercial General Liability.  In accordance
                 with the above, the Systems Provider and any subcontractor
                 shall maintain the following insurance: $1 million per
                 occurrence combined single limit, $2 million general
                 aggregate, and will include coverage for contractual
                 liability, use of independent Systems Providers and Products
                 and completed operations.

         (b)     Business Automobile Liability Insurance.  Coverage or owned,
                 hired, leased, rented and non-owned vehicles in the amount of
                 $1 million combined single limit per occurrence for bodily
                 injury and property damage.

         (c)     Worker's Compensation & Employers' Liability Insurance.
                 Workers' Compensation in the maximum amount(s) and with
                 benefits required by the laws of the state in which the Work
                 is performed and the state(s) the employees are hired, if the
                 state(s) are other than that in which the Work is performed.
                 Employers' Liability with minimum limit of liability of:
<TABLE>
                  <S>                             <C>
                  Bodily Injury by Accident       $1 million each accident
                  Bodily Injury by Disease        $1 million policy limit
                  Bodily Injury by Disease        $1 million each employee
</TABLE>

                 A combination of primary and excess/umbrella liability
                 policies will be acceptable, as a means to meet the limit
                 required under this Agreement.  The required minimum limits of
                 the coverage shown above DO NOT limit or diminish the Systems
                 Provider's liability under this Agreement.

                 The Systems Provider will submit to MCI a standard "Accord"
                 insurance certificate for comparable form acceptable to MCI
                 signed by an authorized representative of such insurance
                 company(ies), certifying that the insurance coverage(s)
                 required hereunder is in effect for the purposes of this
                 Agreement.  If the event Systems Provider fails to maintain
                 adequate coverage as outlined above in this Article, Systems
                 Provider will notify MCI of such a lapse.  In addition, if
                 System Providers coverage lapses Systems Provider will have
                 thirty (30) days to obtain adequate coverage as outlined
                 herein.

                 The Systems Provider, its subcontractor and its insurers shall
                 waive all rights of recovery against MCI for any injuries to
                 persons or damage to property related to performance of this
                 Agreement.  

                 The Systems Provider and its subcontractor shall ensure full 
                 compliance with terms of the Occupational Safety and Health 
                 Administration (OSHA) and all local jurisdiction's safety and 
                 health regulations during the full term of this Agreement.

                 The Systems Provider shall submit to MCI certificates of
                 insurance evidencing the above coverage.  Should the Systems
                 Provider at any time neglect or refuse to provide the
                 insurance required herein, or should such insurance be
                 canceled or non-renewed, MCI shall have the right to terminate
                 this contract, or  secure substitute coverage whose cost shall
                 be deducted from payments owed the Systems Provider.

                 The Systems Provider, at its own expenses, shall indemnify and
                 hold harmless against any and all





                                     - 18 -
<PAGE>   19
                 claims, expenses (including attorneys' fees) from loss or
                 liability for damage to property including property owned,
                 leased or borrowed by MCI and injuries, including death, to
                 all persons to the extent arising out of Systems Provider's
                 performance of this Agreement, unless by reasons of any and
                 all acts or omissions or negligence by MCI, its agents or
                 employees.

contained in this Agreement shall be made to MCI within thirty (30) days of
receipt of notice of same day Systems Provider.

21.3     Attorneys' Fees and Court Costs.  In the event, either party  takes
action to enforce this Agreement or to recover damages for a breach by the
other party,  each party will be responsible for their own fees, expenses and
court costs.

21.4     Indemnification.  Systems Provider agrees to indemnify and hold
harmless MCI its affiliates, directors, officers and employees, from any and
all claims, damages, fines, penalties, attorneys' fees, court costs or other
consequences arising out of Systems Provider's breach of any covenant or
representation set forth herein or Systems Provider's failure to abide by the
terms of this Agreement.

22.      LIENS

22.1     As MCI requires, before submitting any invoice for payment, or at any
other time that MCI requires, Systems Provider shall deliver to MCI a
satisfactory release of any and all liens for which System Provider has under
their control arising in connection with the Products and Work under this
Agreement.

22.2     Systems Provider shall dispose of any claim and defend any suit or
injunction brought to enforce any lien arising from the performance and/or use
of any Products and Work  under this Agreement, and shall pay all expenses
associated with such proceedings.

22.3     MCI may withhold from any payment or consideration otherwise due
Systems Provider, any sum that MCI has reason to believe may be needed to
satisfy any lien arising out the Work under this Agreement.  Prior to the time
of any such withholding, MCI shall notify Systems Provider in writing of the
nature of the lien and the amount of money to be withheld pursuant to this
Article and afford Systems Provider reasonable opportunity to satisfy the lien.

22.4     Systems Provider shall reimburse MCI for all monies, including all
costs and reasonable attorneys' fees, incurred by MCI in removing liens arising
out of the Work under this Agreement.  Such reimbursement may be deducted from
any payment or consideration otherwise due Systems Provider.  Systems Provider
shall, upon written request by MCI, promptly pay MCI any amounts due under this
Article.

         (b) It is expressly agreed that each provision of this Agreement that

                           MASTER RESELLER AGREEMENT
                                    BETWEEN
                        SPRINT/UNITED MANAGEMENT COMPANY
                                      AND
                                VISUAL NETWORKS


This MASTER RESELLER AGREEMENT ("Agreement") effective August 23, 1996
("Effective Date"), between Sprint/United Management Company, a Kansas
corporation, ("Sprint"), with offices located at 8140 Ward Parkway, Kansas
City, Missouri 64114 and Visual Networks, a Delaware corporation ("Supplier"),
with offices located at 2092 Gaither Road, Rockville, MD 20850.

                                   BACKGROUND

Supplier designs, develops, manufactures, and sells electronic equipment
("Equipment") and firmware and software as further defined in Section 13, below
("Software"), (collectively, "Products"), including auxiliary installation,
training, and technical and marketing support services ("Services"); and

Sprint desires to purchase or license various Products and Services from
Supplier that Sprint expects to use itself, or resell or sublicense to others
solely  in association with Sprint network Services provided to Sprint or
Sprint's customers ("Customers"), and Supplier is willing to sell and license
the Products to Sprint and provide Services subject to the terms of this
Agreement.

The parties agree as follows:

1.0      SCOPE

         (a)     This Agreement contains the terms that will apply to any
                 contract or purchase order("Order") that Sprint may place with
                 Supplier during the term of this Agreement for Products and
                 Services offered by Supplier more fully described in Exhibit
                 A, attached to and incorporated in this Agreement.

                 In addition, Sprint may issue a non-binding yearly Order
                 ("Blanket Order") which will apply to Products ordered during
                 that year.  During a given year, Sprint may amend from time to
                 time the Blanket Order.  The parties agree that the Blanket
                 Order does not obligate Sprint to any dollar amount or volume
                 of purchases of Product and is only intended to facilitate in
                 order administration.  

                 Under a Blanket Order, Sprint will issue a document for the
                 purchase of Product under it ("Release").  A Release commits
                 Sprint to the purchase of the specific dollar amount or
                 quantity set forth in that Release. In addition, a Release
                 commits Supplier to ship the Product identified in the Release
                 and invoice Sprint in accordance with this Agreement.

         (b)     The terms of this Agreement control over any additional or
                 inconsistent terms found in any Order under this Agreement or
                 in any acknowledgment or other form used by Supplier, or any
                 exhibits attached to this Agreement.

         (c)     The Order becomes a binding obligation of the parties when
                 Supplier signs and returns to Sprint an acceptance copy of the
                 Order or begins performance of the Order, whichever occurs
                 first.

         (d)     This Agreement is entered into by Sprint on its own behalf and
                 for the benefit of all Sprint Corporation affiliated entities
                 ("Sprint Affiliates") as set forth in Exhibit C.  The term
                 Sprint Affiliate includes: a) controlled Sprint Affiliates,
                 meaning any entity in which Sprint Corporation or its
                 wholly-owned affiliates has practical management control over
                 the entity by virtue of majority stock ownership or an
                 equivalent ownership interest, b) uncontrolled Sprint
                 Affiliates, meaning any entity in which Sprint Corporation
                 directly or indirectly holds an equity or similar interest,
                 but the interest does not give practical management control,
                 or c) remote Sprint Affiliates, meaning parent entities of
                 joint ventures of which Sprint or Sprint Affiliates are a
                 part, telecommunications entities which have an affiliation
                 with those joint ventures, and business customers of Sprint of
                 Sprint Affiliates.

                 Any controlled Sprint Affiliate may automatically execute a
                 Contract Order under this Agreement. Subject to negotiation
                 and upon approval by Sprint's Material & Services Management
                 Department ("M&SM"), Supplier will accept any uncontrolled or
                 remote Sprint Affiliate Contract Order. All references to
                 Sprint refer equally to Sprint Affiliates executing Contract
                 Orders with terms in accordance with this Agreement.  No
                 commitment is made by Sprint or any Sprint Affiliate, nor any
                 liabilities accepted, except that set forth in a properly
                 signed Contract Order.  All communications and invoices must
                 be directed to the Affiliate issuing the Contract Order under
                 the instructions issued in the Contract Order.  Services
                 performed on behalf of any Sprint Affiliate will be billed to
                 or collected from only that Affiliate.  Only the Sprint
                 Affiliate issuing a specific Contract Order under this
                 Agreement will incur any obligation or liability to Supplier
                 for any claim which may arise from or relate to that Contract
                 Order.

          (e)    Sprint is not committed to purchasing any minimum Order or
                 aggregate dollar volume of Products or Services during the
                 term of this Agreement, however, Sprint may provide monthly
                 and yearly estimates of Product purchases ("Forecast") for
                 planning purposes.  Any Forecast provided to Supplier by
                 Sprint is not a commitment on Sprint's part to purchase
                 certain dollar amounts or quantities.

                 this Agreement.

         (b)     Either party may terminate this Agreement upon 30 days' prior
                 written notice to the other party if the other party
                 materially breaches the Agreement and fails to cure the breach
                 within 30 days of written notice of the breach.

         (c)     Either party may terminate this Agreement upon written notice
                 to the other party, if the other party is placed in
                 liquidation or receivership, if a petition of voluntary or
                 involuntary bankruptcy is filed against it and if the petition
                 is not dismissed within 30 days, or if it fails to satisfy a
                 final and valid court judgment for payment of money.

         (d)     This Agreement, including any  Order, may be terminated
                 immediately at any time by Sprint without penalty if there is
                 any change in control or ownership of Supplier to a direct
                 competitor of Sprint (as reasonably determined by Sprint).  If
                 permitted under applicable securities law, Supplier must give
                 Sprint no less than 30 days written notice of any change in
                 control or ownership of Supplier.  This subsection does not
                 apply in the event of Supplier's acquisition as a
                 publicly-traded company.

         (b)     Supplier warrants that the terms of this Agreement and the
                 prices on Exhibit A are no less favorable than the terms given
                 to any third party that purchases or licenses similar Products
                 or Services from Supplier under similar terms and conditions.
                 If Supplier offers more favorable prices and terms to any
                 Customer during the term of this Agreement, the prices and
                 terms will be applicable to Sprint Orders.  Supplier warrants
                 that the prices on Exhibit A are complete and include, but are
                 not limited to, purchase price, maintenance fees, taxes,
                 packaging, labeling, custom duties, storage and insurance.  In
                 determining whether an agreement is of similar scope and the
                 consideration is less, all the terms of this Agreement and
                 that agreement will be analyzed as a whole.

         (c)     Post Term Maintenance.  At Sprint's option at the end of the
                 Term, Supplier will offer maintenance Services under the terms
                 of this Agreement at an annual cost not to exceed ***% of the
                 cumulative sales of ASEs, PAMs, PACSs, & MICs, as defined in

                 (ii)     the date shipment was made and the shipping point for
                          Products;

         (b)     Sprint may specify additional invoicing instructions on the
                 Order.  Supplier may not invoice Sprint until Products are
                 shipped, or Services have been accepted by Sprint.

         (a)     Delivery of Products will be F.O.B. Origination Freight
                 collect, and title and risk of loss will pass to Sprint, upon
                 delivery to Sprint carrier.  Supplier agrees to follow
                 Sprint's shipping instructions, as detailed in Exhibit B,
                 Sprint Transportation Routing Guide.

         (b)     If Supplier fails to meet the delivery date, Sprint may direct

                 Supplier's account, or, in accordance with Paragraph 7,
                 Cancellation for Cause, cancel all or part of the Order.  If
                 Products are delivered ahead of the delivery date, Sprint may:
                 (i)      return the Products at Supplier's expense for early
                          delivery; or
                 (ii)     withhold payment for the Products until after the
                          specified delivery date; or
                 (iii)    place Products in storage for Supplier's account

                 the prorated volumes, delivery will occur consistently within
                 *** days.

                 ***

         (d)     The name, addresses and contact person of Supplier's
                 Affiliates and distributors, through which any Services may be
                 ordered by Sprint, are set forth in Exhibit C.  Supplier will
                 notify Sprint, in writing, of any changes in the Affiliates
                 and distributors on Exhibit C.

6.0      INSPECTION, ACCEPTANCE AND QUALITY CONTROL

         (a)     Sprint may inspect Products according to an agreed upon
                 incoming inspection procedure and rejection rate.  Products
                 that fail to meet inspection criteria will be returned to
                 Supplier, at Supplier's expense.  Supplier will pay for
                 reshipping conforming Products to Sprint.  Sprint may place a
                 hold on all pending Orders until Supplier has demonstrated
                 that the cause for rejection has been corrected.  If the cause
                 for rejection is not corrected within 30 days after rejection,
                 Sprint may cancel outstanding Orders without further
                 obligation or liability.  Sprint may conduct a site inspection
                 at Supplier's facility during business hours by providing 7
                 days notice to Supplier.

          (b)    If Supplier becomes aware of any problem with a Product that
                 is of a safety, regulatory compliance, environmental
                 compliance, or serious performance nature, and changes the
                 design or documentation related to the Product, Supplier must
                 implement the change in accordance with Exhibit D.

         (c)     In order for the Products to be connected to the Sprint public
                 communications network, the Products must pass Sprint's
                 certification tests.  This includes any material modifications
                 made to any Products to ensure operability and backward
                 compatibility with Sprint's network.  Such materiality shall
                 be determined by Sprint.  Accordingly, Supplier will provide
                 Sprint units of Product at no charge, along with cables, and
                 Documentation, to enable Sprint to perform its certification
                 process.

7.0      CANCELLATION

         (a)     Cancellation for Cause.  Sprint may cancel an Order, in whole
                 or in part, if Supplier fails or refuses to deliver Products
                 or Services as ordered on the delivery date, or if Supplier is
                 not performing in accordance with Supplier-published
                 specifications.  Sprint's acceptance of all or any part of the
                 Products or Services will not waive claims which Sprint may
                 have for delays.

                 If Sprint cancels an Order in whole or in part for cause,
                 Sprint may procure similar Products or Services from a third
                 party, and Supplier must pay Sprint for the excess cost for
                 the replacement Products or Services to be capped at 200% of
                 Sprint's purchase price for that Order.  If cancellation is
                 partial, Supplier must continue the performance of the
                 remaining portion of the Order

         (b)     Cancellation for Convenience:

                 (i)      Prior to delivery, for Releases and orders under ***,
                          Sprint may, without penalty or other liability
                          reschedule or cancel a delivery.  For Releases or
                          Orders over ***, Sprint may cancel a Release or Order

                 business days, Sprint may reject the Equipment and Supplier
                 will refund to Sprint all monies paid in connection with that
                 Equipment including but not limited to shipping..

         (c)     Supplier warrants that all Products, when delivered, conform

                          Supplier will, at its option, correct or replace any
                          defective Software version or update at Supplier's
                          expense, if the Software was installed properly and
                          used in accordance with Supplier's specification.


                 ii)      Supplier has the full power and authority to grant
                          the license granted Sprint under this Agreement with
                          respect to the Software, and neither the license to
                          nor use by Sprint of the Software, as permitted under
                          this Agreement, will in any way constitute an
                          infringement or other violation of any copyright,
                          patent, trade secret, trademark, nondisclosure, or

                          to fulfill its obligations under this Agreement.

                 iv)      During Term or when Maintenance is provided after the
                          Term, Supplier guarantees that its maintenance and

                          versions of the Software licensed under this
                          Agreement.

         (e)     Supplier warrants all Services provided will be performed in a
                 workmanship like and timely manner, in conformance with the
                 highest professional standards of the industry and to Sprint's
                 reasonable satisfaction.  Defective or deficient Services will
                 be corrected, or, at Sprint's option, monies paid to Supplier
                 in connection with the Services will be refunded.

         (f)     Additional Supplier warranties and maintenance Services which
                 must be provided by Supplier are included in Exhibit D.

         (g)     The warranties are made solely to and for the benefit of
                 Sprint and its Customer.  Supplier makes no other warranties
                 with respect to the products or any services and disclaims all
                 other warranties, .  Sprint's sole remedy with respect to any
                 warranty or defect is as stated above.

11.0     OWNERSHIP

         (a)     All Equipment, materials, drawings, Software or data of every
                 description that Supplier receives directly or indirectly from
                 Sprint or from a third party on behalf of Sprint, or that is
                 paid for in whole or in part by Sprint, is the property of
                 Sprint ("Sprint-owned").  Supplier must mark all such property

                 Products as part of a new and separate executed agreement.
                 The purpose of such agreement will be to define possible
                 specific developments unique to Sprint (for which Sprint would
                 pay for development) and possible specific, defined
                 restrictions on Supplier's distribution rights for those
                 developments.

                 suppliers ("Proprietary Information").

         (b)     This Agreement creates a confidential relationship between
                 Sprint and Supplier.  Sprint and Supplier will keep
                 Proprietary Information confidential and, except as authorized
                 by Sprint or Supplier in writing, Supplier and Sprint may only
                 use Proprietary Information to perform the Services or provide
                 the Products as required under this Agreement, and may only
                 make copies necessary for performing or reselling the Services
                 or providing the Products.  Supplier or Sprint will label all
                 Proprietary Information as proprietary or if disclosed in an
                 intangible format, confirm in writing within 30 days of
                 disclosure.  Upon cessation of work, or upon Sprint's or
                 Supplier's request, Sprint or Supplier will return all
                 documents and other materials in their control that contain
                 or relate to Proprietary Information.

         (c)     Sprint may require signed non-disclosure agreements from
                 Supplier's employees, agents or subcontractors.

         (d)     Proprietary Information does not include information that
                 Supplier or Sprint can demonstrate by written documentation:

                 (i)      is rightfully known to Supplier or Sprint prior to
                          negotiations leading to this Agreement;

                 (ii)     is independently developed by Supplier or Sprint
                          without any reliance on Proprietary Information; or

                          lawfully obtained by Supplier or Sprint from a third
                          party.

         (e)     Supplier and Sprint acknowledge that disclosure of Proprietary
                 Information by Supplier or Sprint will cause irreparable
                 injury to Sprint or Supplier, Sprint's Customers and other
                 suppliers, that is inadequately compensable in monetary
                 damages.  Accordingly, Sprint or Supplier may seek injunctive
                 relief in any court of competent jurisdiction for the breach
                 or threatened breach of this Section 12, in addition to any
                 other remedies in law or equity.

13.0     LICENSE OF SOFTWARE

         (a)     "Software" means any program stored on any media, including
                 but not limited to, magnetic tape, semiconductor device, disk,
                 or other memory device, or computer memory and including
                 related items.  Supplier grants to Sprint a non-exclusive,
                 fully paid-up, perpetual license to use the object code of the
                 Software with the right to sublicense the object code to its
                 Customers, provided that the object code will only be used in
                 connection with the Products for which it was acquired and by
                 Sprint's consultants and agents on a need-to-know basis.  This
                 right to use and sublicense the object code is subject to
                 payment of applicable license fees.

         (b)     Sprint acknowledges that Supplier claims that the Software is
                 proprietary to Supplier and third parties from whom Supplier
                 has acquired license rights.  Title to the Software will
                 remain with Supplier or the third-party owners.  Sprint will
                 enter into a software license agreement with its Customers,
                 prior to providing the object code of the Software.  The
                 software license will be either a separate agreement or a
                 master sublicense agreement under which various products are
                 sublicensed by Sprint and will contain provisions that are no
                 less restrictive than those of this Section 13.

         (c)     Sprint may copy the object code of the Software for the
                 purpose of distributing it to its Customers.  Additionally,
                 Sprint, its distributors, Customers and prime contractors may
                 copy the object code of the Software for back-up or archival
                 purposes.  Each copy of the Software made by Sprint, its
                 distributors, Customers, and prime contractors will include
                 the proprietary notice contained in the Software as delivered
                 by Supplier.

         (d)     During the Term of this Agreement or when maintenance is
                 provided following the Term, Sprint may distribute copies of
                 any Software correction, modification, or update provided to
                 Sprint or its Customers at no additional cost.

         (e)     Sprint will not, and will not assist any third party to,
                 modify, reverse assemble, reverse compile or reverse engineer
                 the Software.

         (f)     The expiration or termination of this Agreement will not
                 terminate the right of Sprint or its Customers to use the
                 Software.

         (g)     Supplier warrants, that it is not necessary for Sprint, or its
                 Customers to obtain a license from any third party in order to
                 use the Products, other than the license granted by Supplier
                 under Sections 13 and 15.

         (h)     Failure to comply with Section 13 is a material breach of this
                 Agreement.

14.0     ESCROW AGREEMENT

         (a)     Within 30 days after the Effective Date, Supplier and Sprint
                 will enter into an escrow agreement ("Escrow Agreement") with
                 an escrow agent.  The Escrow Agreement will provide for the
                 delivery of items necessary to recreate, modify, maintain and
                 use the Software, including without limitation, flow chart and
                 diagrams, compilers, operating Software, and relevant
                 documentation, such as design documentation and the document
                 environment ("Source Code") to the escrow agent, and require
                 the Supplier to deposit in escrow any modifications or
                 enhancements to the Source Code of the Software within 45 days
                 after provision of such modifications and/or enhancements to
                 Sprint or its Customers.  In addition, Sprint will be
                 permitted to inspect the Source Code, which has been deposited
                 in escrow, through an independent third-party, to verify that
                 the Source Code has been deposited and that it contains
                 everything needed to use and maintain the Software.  The fees
                 of the escrow agent will be paid by Sprint.

         (b)     Sprint will have the right to obtain a copy of the Source Code
                 from the escrow agent to maintain, modify and enhance the
                 Software for itself and sublicensees, subject to the
                 confidentiality provisions of this Agreement, and only if one
                 or more of the following events occurs:

                 (i)      Supplier willfully refuses for more than 30 days to
                          deliver the Software to Sprint, or to support the
                          Software licensed by Sprint to a Customer, in breach
                          of Supplier's obligations under this Agreement, or

                 (ii)     Supplier is unable to deliver the Software to Sprint
                          due to Supplier's voluntary or involuntary
                          bankruptcy, insolvency, dissolution or cessation of
                          active business operations for a period of more than
                          30 days.

                 If one or more of the above listed events occurs, Supplier
                 automatically, by the terms of this Agreement, grants to
                 Sprint a personal (except for third parties permitted to work
                 with the source code pursuant to Subsection (c) below,
                 non-exclusive, royalty free, worldwide license to use the
                 Source Code for the purpose of meeting its support obligations
                 to itself and its Customers.  The 30-day period referred to
                 in subsections (i) and (ii) commences when Supplier receives
                 written notice from Sprint that the event has occurred.

20.0     ARBITRATION

         (a)     Any dispute arising out of or relating to this Agreement,
                 including any issues relating to arbitrability or the scope of
                 this arbitration clause, will be finally settled by
                 arbitration in accordance with the rules of the American
                 Arbitration Association applying the substantive law of Kansas
                 without regard to any conflict of laws provision.  The
                 arbitration will be governed by the United States Arbitration
                 Act, 9 U.S.C. Section 1 et seq., and judgment upon the award
                 rendered by the arbitrator(s) may be entered by any court with
                 jurisdiction.  The arbitration will be held in the Kansas
                 City, Missouri metropolitan area.  The arbitrators are not
                 empowered to award damages in excess of compensatory damages
                 and each party waives any damages in excess of compensatory
                 damages.  Notwithstanding the foregoing, Sprint or Supplier
                 may bring a claim for injunctive relief as provided in Section
                 12(e) in a court of competent jurisdiction without first
                 submitting the matter to Arbitration.

         (b)     Claims made by Supplier may only be brought against the Sprint
                 Affiliate which issued the Order giving rise to the claim.

21.0             FEDERAL REQUIREMENTS

         (a)     Sprint's Status as a Government Contractor.  If Sprint or the
                 federal government determines that this Agreement supports
                 specific requirements included in a Sprint contract or
                 subcontract with the federal government, Supplier will be
                 subject to certain federal acquisition regulations ("FAR's")
                 contained in Sprint's contract or subcontract.  Supplier will
                 be subject only to FAR's that must be included in all
                 subcontracts as a matter of law.  The applicable FAR will be
                 attached to the affected Order.

         (b)     Small Business/Small Disadvantaged Business Reporting.  If

                 Services purchased by Sprint that are subcontracted to firms
                 that are Small Businesses, Small Disadvantaged Businesses, or
                 Women-Owned Businesses under Small Business Administration
                 Regulations.  These dollars will be reported annually in

         (b)     Supplier Performance.  Time is of the essence in Supplier's

                 not to make any commitment in the name of or which purports to
                 be binding on the other.

         (d)     Independent Contractor

                          independent contractors for all purposes and at all

                          by any person or governmental agency which arise

                          and not for transportation or per diem costs
                          associated with replacing the individual.  Supplier
                          will submit additional resumes to Sprint for purposes
                          of filling a vacancy at no additional charge.

                 (vi)     Supplier and Sprint will require its employees,
                          agents and subcontractors to comply with the terms
                          and conditions of this Agreement.

         (f)     Survival.  Numbered provisions 9, 10 ,11, 12, 13, 14, 15, 16,
                 17, 18, 20, 22(j) and (k) will survive the expiration or
                 termination of this Agreement, as well as provisions in this
                 Agreement that by their content are intended to survive the
                 performance, termination or cancellation of this Agreement.

         (g)     Severability.  If a provision of this Agreement is
                 unenforceable, the remaining provisions will remain in effect,
                 to be construed as if the unenforceable provision were
                 originally deleted.

MEDIATION

If a dispute arises out of or relates to this Agreement, or its breach, and the

negotiation, the parties shall attempt to resolve the dispute through non-
binding mediation by submitting the dispute to a sole mediator selected by the
parties or, at the option of a party, to mediation by the American Arbitration
Association ("AAA").  Each party shall bear its own expenses and an equal
share of the expenses of the mediator and the fees of the AAA.  The parties,
their representatives, other participants and the mediator shall hold in
confidence the existence, content and result of the mediation.  If  the dispute
is not resolved by the mediation, the parties shall have the right to resort to
any remedies permitted by law.  Defenses based on the passage of time are
suspended upon submitting the dispute to the mediator and during the mediation.
The time period during the mediation shall be disregarded in calculating such
defenses.   Nothing in this clause shall be construed to preclude any party
from seeking injunctive relief in order to protect its rights during

sell, license or Lease to AT&T any or all Equipment, Software, Services or
Materials described in this Agreement which  AT&T may require, nor requires the

shall become acquainted  with conditions governing the delivery, receipt and
storage of Materials and Equipment at the site of the Services so that VISUAL

other property from damage due to VISUAL's performance of the Services.

SEVERABILITY

If any of the provisions of this Agreement shall be invalid or unenforceable,
the invalidity or unenforceability shall not invalidate or render
unenforceable the entire Agreement or Order, but rather the entire Agreement or
Order shall be construed as if not containing the particular invalid or
unenforceable provision or provisions, and the rights and obligations of the
parties shall be construed and enforced accordingly.

SHIPPING

VISUAL shall do all of the following:

1.   Ship the Equipment, Software and Materials to the site designated in an
     Order by the date  set forth in the Order in accordance with specific
     shipping instructions,

agreed to in the OPERATING SYSTEM SOFTWARE clause in Article II and in the
LICENSE GRANT and INTELLECTUAL PROPERTY RIGHTS clauses in Article III.

with VISUAL.

WAIVER

The failure of either party at any time to enforce any right or remedy
available to it under this Agreement or otherwise with respect to any breach
or failure by the other party shall not be construed to be a waiver of that
right or remedy with respect to any other breach or failure by the other party.

WORK DONE BY OTHERS

If any part of the Services performed by VISUAL is dependent upon Services done
by others, VISUAL shall inspect and promptly report to AT&T any defect that
renders the other work unsuitable for VISUAL's proper performance.  VISUAL's

for VISUAL's performance of the Services or other work.

Orders issued pursuant to this Agreement and shall constitute the entire
agreement between the parties with respect to the subject matter of this
