                                                DESIGN AND DEVELOPMENT AGREEMENT
================================================================================

     THIS DESIGN AND DEVELOPMENT AGREEMENT ("Agreement") is entered into as of
May 12, 1998 ("Effective Date") by and between VLSI Technology, Inc., with
offices at 1109 McKay Drive, San Jose, California 95131 ("VLSI") and ELECTRONICS
ACCESSORY SPECIALISTS INTERNATIONAL, INC. (1) with offices at 7955 E. Redfield
Road, Scottsdale, AZ 85260 ("Buyer").

               (1)  DBA MOBILITY ELECTRONICS

     WHEREAS, Buyer requires a design (the "Product Design") for a particular
integrated circuit (the "Product"), meeting the general specifications to be
established pursuant to the Statement of Work, attached hereto as EXHIBIT A (the
"Statement of Work"); and

     WHEREAS, Buyer intends to market said Product in significant quantities;
and

     WHEREAS, VLSI has expertise in the design of integrated circuits, and
believes it can produce a design for Product;

     NOW THEREFORE, the parties hereto agree as follows:

1.   DESIGN RESPONSIBILITIES

VLSI and Buyer agree to perform the activities set forth in the Statement of
Work and to complete each such activity by the Target Completion Date as set
forth therein. To the extent there is delay in completion of any activity
required by the Statement of Work, there shall be an equal extension of the
target completion date of all subsequent activities. Buyer and VLSI shall each
indicate acceptance of completion of each relevant design step by executing the
completion sign-off for such step on the Statement of Work, or a copy of the
Statement of Work. All executed copies of the Statement of Work shall be deemed
merged into and become a part of this Agreement. Any documents listed as
reference documents in the Statement of Work, including but not limited to,
specifications, description of training, or special requirements shall be deemed
incorporated herein, but only to the extent such documents are not in conflict
with other terms of this Agreement.

2.   CHANGES TO SPECIFICATION

Any changes to the specifications of the Product requested by Buyer shall be
subject to mutual agreement by both parties and the Statement of Work and/or
Payment Schedules, attached hereto as EXHIBIT B, shall be adjusted accordingly,
as mutually agreed by VLSI and Buyer.

3.   INSPECTION

During the term of this Agreement, each party shall keep the other advised of
the progress of its work and shall permit appropriate representatives to visit
its facilities upon reasonable notice during normal business hours.

4.   EXCLUSIVE RIGHTS

A.   Buyer shall have exclusive rights to the Product Design completed by VLSI
     during the term of this Agreement. Such Product Design shall also include
     any future versions of the Product designed by VLSI for Buyer. VLSI shall
     retain title to and possession of photomasks and database tapes, but shall
     not use any photomasks or database tapes unique to the Buyer's Product
     Design for any purpose other than the manufacture of Product in accordance
     with Buyer's instructions, and shall destroy such photomasks or tapes upon
     Buyer's written request. VLSI agrees that it shall not sell the Product
     (including any future versions of the Product) to any third party.

B.   Buyer understands and agrees that the exclusive rights granted hereunder
     are rights to the Product as a whole. Parts of the Product, excluding any
     of Buyer's Confidential Information but including, but not

     limited to, components commonly known as base arrays, standard cells, or
     megacells, are the property of VLSI and may be used in other designs
     completed by VLSI for itself or third parties. No rights are granted to
     Buyer to use any part of the Product except to the extent it is part of the
     complete Product.

C.   Buyer has identified and disclosed to VLSI certain concepts and approaches
     relative to the Product, the Statement of Work, and Buyers docking station
     strategy, specifically including its approach to split a PCI bridge and
     recreate the PCI bus at a remote location (i.e. in a dock) by means of
     serializing the PCI bus and transmitting over a high speed, low wire count
     cable (collectively the "Concepts"). Such Concepts shall be considered
     Confidential Information and subject to the provisions of Section 9 hereto
     and as such, VLSI agrees to adhere to such confidentiality restrictions
     including, without limitation, the express prohibition against selling or
     otherwise marketing any such Confidential Information received from Buyer.

5.   PAYMENT

A.   Buyer shall pay VLSI for Product design and development in accordance with
     the Payment Schedule. Each payment shall be in U.S. dollars and is due
     within thirty (30) days of receipt of invoice. Shipments, deliveries, and
     performance of work shall at all times be subject to the approval of VLSI's
     credit department which approval shall not be unreasonably withheld. VLSI
     may at any time decline to make any shipments, deliveries or perform any
     work except upon receipt of payment/security or upon terms and conditions
     satisfactory to VLSI's credit department.

B.   Design and development fees once paid are non-refundable.

6.   TERM/TERMINATION

A.   This Agreement will become effective as of the Effective Date and will
     continue in full force and effect through the completion and sign-off of
     the Statement of Work, unless earlier terminated as stated below, whereupon
     it will expire without notice unless the parties agree in writing to renew
     this Agreement prior to such expiration or termination. Notwithstanding
     anything herein to the contrary, upon termination of this Agreement, the
     terms and provisions of this Agreement shall be deemed to be terminated and
     of no further force or effect, except the provisions of Sections 4, 9 and
     11(M) hereof shall survive the termination of this Agreement.

B.   Buyer may terminate this Agreement with thirty (30) days written notice to
     VLSI. If this Agreement is terminated for any reason, except for a breach
     hereof by VLSI, prior to acceptance of prototypes, Buyer shall pay VLSI at
     the applicable rate set forth in the Payment Schedule for all services
     provided by VLSI. In the event Buyer has agreed to pay by milestone, Buyer
     shall pay for all milestones achieved in addition to the amount of the next
     following milestone.

9.   CONFIDENTIAL INFORMATION
A.   "Confidential Information" shall mean that information of either party

     shall not disclose such Confidential Information to any person or persons
     who do not need to have knowledge of such Confidential Information in the
     course of their employment with Recipient. Recipient shall use the same
     degree of care as it employs with respect to its own confidential and
     proprietary information and at a minimum to exercise reasonable care.

C.   It is expressly understood that Recipient shall not be liable for
     disclosure of any Confidential Information if the same:

     i.   was in the public domain at the time it was disclosed;

     ii.  was known to Recipient at the time of disclosure, as evidenced by
          Recipient's written records;

     iii. was independently developed by Recipient; or

     iv.  becomes known to Recipient, on a non-confidential basis, from a source
          other than the other party hereto, without breach of this Agreement by
          Recipient.

10.  LIMITATION OF LIABILITY

     In no event shall either party be liable for any indirect, special,
     incidental or consequential damages resulting from its performance or
     failure to perform under this Agreement, or the furnishing, performance, or
     use of any goods or services sold pursuant hereto, whether due to a breach
     of contract, breach of warranty, or such party's negligence. Neither
     party's liability hereunder shall exceed the amount of monies paid
     hereunder.

11.  GENERAL

A.   Neither party may assign its rights or obligations under this Agreement
     without the prior consent of the other party, and any purported assignment
     without such consent shall have no force or effect, except that a party may
     assign this Agreement incident to the transfer of all or substantially all
     of its business. Subject to the foregoing, this Agreement shall bind and
     inure to the benefit of the respective parties hereto and their successors
     and assigns.

B.   Neither party is authorized to act for or on the behalf of the other party
     under this Agreement. Each party is an independent contractor, and no
     principal/agent or partnership relationship is created between them by this
     Agreement.

<PAGE>   4

C.   No failure or delay by either party to enforce or take advantage of any
     provision or right under this Agreement shall constitute a subsequent
     waiver of that provision or right, nor shall it be deemed to be a waiver of
     any of the other terms and conditions of this Agreement.

D.   Neither party to this Agreement shall be liable for its failure to perform
     any of its obligations hereunder during any period in which such
     performance is prevented by any cause beyond its reasonable control. In the
     event of any such delay the date of delivery or performance hereunder shall
     be extended by a period equal to the time lost by reason of such delay.

E.   This Agreement shall be governed by and interpreted in accordance with the
     laws of the State of California, USA.

F.   The prevailing party in any legal action arising out of, or related to this
     Agreement shall be entitled, in addition to any other rights and remedies
     it may have, to reimbursement for its expenses incurred in such action,
     including court costs and reasonable attorney's fees.

G.   Unless otherwise stated herein, amounts stated as payable under this
     Agreement do not include customs duties or sales, use, excise or other
     similar taxes payable hereunder, and the same shall be added to such
     amounts.

H.   Data and products provided hereunder may not be exported from the United
     States, or re-exported from any other country, except in compliance with
     United States Export Control Laws, and the parties agree to operate in full
     compliance with these and all other applicable laws.

I.   All notices or communications to be given under this Agreement shall be in
     writing and shall be deemed delivered upon hand delivery, confirmed
     facsimile communication, or three (3) days after deposit in mail of the
     home country of the party, postage prepaid, by certified, registered or
     first class mail, addressed to the parties at their addresses set forth
     above.

J.   In the event that any provision of this Agreement is prohibited by any law
     governing its construction, performance or enforcement, such provision
     shall be ineffective to the extent of such prohibition without invalidating
     thereby any of the remaining provisions of the Agreement.

K.   The terms and conditions of this Agreement may not be superseded, modified,
     or amended except in writing which states that it is such a modification,
     and is signed by an authorized representative of each party hereto.
     However, VLSI may modify the specifications of Products sold hereunder, if
     such modification does not change the Product's form, fit or function.

L.   This Agreement, including exhibits, constitutes the entire Agreement
     between the parties as to the subject matter hereof, and supersedes and
     replaces all prior or contemporaneous agreements, written or oral,
     regarding such subject matter, and shall take precedence over any
     additional or conflicting terms which may be contained in either party's
     purchase orders or order acknowledgment forms.

M.   Each party agrees that money damages would not be a sufficient remedy for
     any breach of this Agreement by the other party, and that each party shall
     be entitled to specific performance as a remedy for a breach hereof, in
     addition to all other remedies available at law or in equity to such party.

                                    RECITALS:

         WHEREAS, the Company is authorized to issue shares of the Company's
$0.001 par value common stock ("COMMON Stock") and the warrant to purchase
shares of Common Stock described herein; and

         WHEREAS, in connection with and in consideration for the payment by the
Purchasers to the Company of a total aggregate consideration of $6,000,000 at
Closing (as hereinafter defined), the Company shall issue to Purchasers that

divided by 80% of the average closing bid price of the Common Stock on the
Nasdaq SmallCap Market for the five consecutive trading days ending one day
prior to the date on which the Company files its registration statement on Form

determined in accordance with such Purchaser's allocated percentage set forth
opposite such Purchaser's name on SCHEDULE I, attached hereto. Purchasers shall
also receive warrants (individually, a "WARRANT" and collectively, the
"WARRANTS") to purchase, in the aggregate, that number of shares (the "WARRANT

acquired, in the aggregate, by Purchasers at the Closing. The exercise price of
the Warrants shall be equal to 140% of the Purchase Price Per Share. Each
individual Purchaser shall receive its pro-rata portion of the Warrants, which
such portion shall be determined in accordance with such Purchaser's allocated
percentage set forth opposite such Purchaser's name on SCHEDULE I, attached
hereto. The Warrants shall be in the form attached hereto as Exhibit A.

                                   AGREEMENT:

representations and warranties hereinafter set forth, and for other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:

                         PURCHASE AND SALE OF SECURITIES

                  1.1 Purchase and Sale of Securities. Subject to the terms and
conditions of this Agreement, and in reliance upon the representations,
warranties and agreements herein contained, on the Closing Date, the Company
shall issue to Purchasers, and Purchasers shall acquire from the Company, the

options, rights, mortgages, pledges, restrictions on transferability of any type
(other than (i) restrictions on transferability as may be applicable under
federal and state securities laws, (ii) as set forth herein or therein and/or
(iii) those created by Purchasers) and Purchasers shall pay on the Closing Date
to the Company an aggregate amount of $6,000,000 (the "CASH CONSIDERATION") by
wire transfer to such account as is designated by the Company to Purchasers in
writing.

                  1.2 Separate Sales. The Company's agreement with each
Purchaser is a separate agreement, and the sale of Shares and Warrants to each
Purchaser is a separate sale.

Company files the Form SB-2, but in no event shall the Closing take place later
than the third business day after the date of this Agreement. The Closing shall
take place at the offices of Brobeck, Phleger & Harrison LLP, 301 Congress Ave.,
Suite 1200, Austin, Texas 78701, or at such other date, time or place as the
parties hereto mutually agree, either verbally or in writing. Such date is
referred to herein as the "CLOSING DATE," and the Closing shall be deemed to be

                                  ARTICLE III

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

         Except as disclosed in a document of even date herewith and delivered
by the Company to Purchasers prior to the execution and delivery of this
Agreement (the "COMPANY DISCLOSURE SCHEDULE"), the Company represents and
warrants to Purchasers as follows:

                  3.1 Organization, Standing and Power. The Company is a
corporation duly organized, validly existing and in good standing under the laws
of its jurisdiction of organization. The Company has the corporate power to own,
lease and operate its properties and to carry on its business as now being
conducted and as proposed to be conducted and is duly qualified to do business
and is in good standing in each jurisdiction in which the failure to be so
qualified and in

                                       2
<PAGE>   6

good standing would have a material adverse effect on the Company. The Company
is not in violation of any of the provisions of its Certificate of Incorporation

preferred stock, par value $0.001 per share, of which there were issued and
outstanding as of the close of business on March 3, 2000, 19,735,416 shares of

similar rights, agreements, arrangements or commitments of any character
obligating the Company to issue or sell shares of its capital stock, (b) notes,

otherwise acquire any shares of Common Stock or any other capital stock of, or

and sale to the Purchasers pursuant to this Agreement and are validly issued.
The Shares are, and, when issued pursuant to the terms and conditions set forth
in the Warrant, the Warrant Shares will be, fully paid and non-assessable, and
no holder of Securities is or will be subject to personal liability with respect
to the obligations of the Company by reason of being such a holder. Other than
as set forth in Section 3.2(d) of the Company Disclosure Schedule, the Shares
and the Warrants are, and the Warrant Shares, when issued, shall be, free of
preemptive rights or rights of first refusal created by statute, the Company's

contained in Sections 4.6, 4.7 and 4.8 of this Agreement, are and shall be

approval, consent, license, order, registration, qualification or decree of, any
court or governmental authority or agency, domestic or foreign is necessary or

Operative Agreements (as hereinafter defined) or for the offering, issuance or
sale of the Securities. The form of certificate that will be used to evidence
the Shares will comply in all material respects with all applicable statutory
requirements, with any applicable requirements of the Certificate of
Incorporation and Bylaws of the Company and with the requirements of the Nasdaq
SmallCap Market.

                  On March 1, 2000, the Company declared a two-for-one stock
split of its Common Stock payable on March 27, 2000 in the form of a dividend of

all outstanding share and per share amounts, and the number and Purchase Price
per share of the Shares and Warrants, shall be deemed to give effect to such
split.

Operative Agreements (a) shall not, with or without notice or lapse of time, or
both, conflict with or constitute a breach of, or default or acceleration event

and Warrants for its own account and not as a nominee or agent, and not with a
view to the resale or distribution of any part thereof, and such Purchaser has

         communications delivered to the Company) to the effect that the SEC
         and/or such state securities law agencies will take no action, or that
         the staff of the SEC and/or such state securities law agencies will
         recommend that the SEC and/or such state securities law agencies, as
         applicable, take no action, with respect to the proposed offer, sale,
         exchange, transfer, pledge or other disposition if consummated.

         All certificates representing the Securities deliverable to such

                  (a) The Company has been duly incorporated and is validly
         existing as a corporation in good standing under the laws of the State
         of Delaware. The Company has corporate power and authority to own,
         lease and operate its properties and to conduct its business as
         described in the Company SEC Documents and to enter into and perform
         its obligations under each of the Operative Agreements.

                  (b) The Securities have been duly authorized for issuance and
         sale to the Purchasers pursuant to this Agreement and, when issued and
         delivered by the Company pursuant to this Agreement against payment of
         the consideration set forth herein or in the Warrants, as the case may
         be, will be validly issued and fully paid and non-assessable, and no
         holder of Securities is or will be subject to personal liability with
         respect to the

                                       9
<PAGE>   13
         obligations of the Company by reason of being such a holder. Other than
         as set forth in Section 3.2(d) of the Company Disclosure Schedule, the
         issuance of the Securities is not subject to preemptive or other
         similar rights of any securityholder of the Company created by statute,
         under the Certificate of Incorporation or Bylaws of the Company or
         under any documents or agreements filed or incorporated by reference by
         the Company with the SEC as exhibits to its registration statement on
         Form SB-2 (Reg. No 333-83315) including all amendments thereto (the
         "SEC EXHIBITS").

                  (c) The Operative Agreements have been duly authorized,
         executed and delivered by the Company. The Operative Agreements
         constitute the valid and binding obligations of the Company,
         enforceable against the Company in accordance with their respective
         terms, except as may be subject to or limited by (i) bankruptcy,
         insolvency, reorganization, arrangement, moratorium, fraudulent
         transfer and other similar laws affecting the rights of creditors
         generally and (ii) general equitable principles (whether relief is
         sought at law or in equity), including concepts of materiality,
         reasonableness, good faith and fair dealing; and except as any rights
         to indemnification and contribution may be limited by federal or state
         securities laws and public policy considerations.

                  (d) Except for Form D filings required to perfect exemptions
         under applicable federal and/or state securities laws and the filing of
         an application to list additional shares of Common Stock with the
         Nasdaq SmallCap Market, no filing with, or authorization, approval,
         consent, license, order, registration, qualification or decree of, any
         court or governmental authority or agency, domestic or foreign is
         necessary or required in connection with the due authorization,
         execution and delivery of the Operative Agreements or for the offering,
         issuance or sale of the Securities.

                  (e) The execution, delivery and performance of the Operative
         Agreements and the consummation of the transactions contemplated in the
         Operative Agreements (including the issuance and sale of the
         Securities) and compliance by the Company with its obligations under
         the Operative Agreements do not and will not, whether with or without
         the giving of notice or lapse of time or both, conflict with or
         constitute a breach of, or default or acceleration event under or
         result in the creation or imposition of any lien, charge or encumbrance
         upon any property or assets of the Company pursuant to any SEC Exhibit
         to which the Company is a party or by which it may be bound (except for
         such conflicts, breaches or defaults or liens, charges or encumbrances
         that would not have a material adverse effect on the Company), nor will
         such action result in any violation of the provisions of the
         Certificate of Incorporation or Bylaws of the Company, or any
         applicable law, statute, rule, regulation, judgment, order, writ or
         decree, known to such counsel, of any government, government
         instrumentality or court, domestic or foreign, having jurisdiction over
         the Company or any of its properties, assets or operations.

         In rendering such opinion, such counsel may rely, as to matters of fact
(but not as to legal conclusions), to the extent they deem proper, on
certificates of responsible officers of the Company and public officials. Such
opinion shall not state that it is to be governed or qualified by, or that it is
otherwise subject to, any treatise, written policy or other document relating to

                                       10

warranties of the parties as contained in this Agreement (including the
Disclosure Schedules) shall survive the Closing and shall terminate on the date
that is one year after the Closing; provided that there shall be no limitation
period for matters involving fraud or intentional misrepresentation nor for
covenants and agreements of the parties.

                  7.2 Statements as Representations. All statements contained in
the Company Disclosure Schedule and any certificate delivered pursuant to this
Agreement shall be deemed representations and warranties within the meaning of
Section 7.1 hereof.

                  7.3 Indemnification by the Company. Subject to the limitations
set forth in this Article VII, the Company hereby agrees to indemnify, defend
and hold harmless Purchasers, any subsidiary, director, officer, employee,
partner, agent or representative of any Purchaser (individually, a "PURCHASER
INDEMNITEE" and collectively, "PURCHASER INDEMNITEES") from and against all
demands, claims, actions or causes of action, assessments, losses, damages,
liabilities, costs and expenses, including, without limitation, interest,
penalties, attorneys' fees and expenses (collectively, "DAMAGES") asserted
against, resulting from, imposed upon or incurred by the Purchaser Indemnitees
or any Purchaser Indemnitee, resulting from, or arising out of any breach of any
representation, warranty or agreement of the Company, contained in or made
pursuant to this Agreement. Exercise of the foregoing indemnification rights
shall be the sole remedy of any Purchaser Indemnitee with respect to any breach
by the Company of its representations or warranties contained in this Agreement.
The maximum aggregate liability of the Company pursuant to this Section 7.3 with
respect to any breach by the Company of such representations or warranties will
be limited to an aggregate of Six Million and 00/100 Dollars ($6,000,000.00),
and $2,000,000 per Purchaser, plus any amounts paid by such Purchaser to
exercise the Warrants, whether such liability is asserted in an action brought
in contract, in tort or pursuant to some other theory and whether the
possibility of such liability was made known to or was foreseeable by the
Company. Accordingly, the Purchasers agree to assume the responsibility for
insuring against or otherwise bearing the risk of greater damages.

                  7.4 Indemnification by Purchasers. Subject to the limitations
set forth in this Article VII, each Purchaser, severally and not jointly, agrees
to indemnify, defend and hold harmless the Company, any subsidiary, director,
officer, employee, agent or representative of the Company (individually, an
"COMPANY INDEMNITEE" and collectively, "COMPANY INDEMNITEES") from and against
all Damages asserted against, resulting from, imposed upon or incurred by the
Company Indemnitees or any Company Indemnitee, resulting from, or arising

                                       11
<PAGE>   15

out of any breach of any representation, warranty or agreement of such Purchaser
contained in or made pursuant to this Agreement. Exercise of the foregoing
indemnification rights shall be the sole remedy of any Company Indemnitee with
respect to any breach by a Purchaser of its representations, warranties or
agreements contained in this Agreement. The maximum liability of each individual
Purchaser pursuant to this Section 7.4 with respect to any breach by such
Purchaser of its representation and warranties will be limited to Two Million
and 00/100 Dollars ($2,000,000) per Purchaser, and Six Million and 00/100
Dollars ($6,000,000) in the Aggregate, plus any amounts paid by such Purchaser
to exercise the Warrants, whether such liability is asserted in an action
brought in contract, in tort or pursuant to some other theory and whether the
possibility of such liability was make known to or was foreseeable by the
Company.

                  7.5 Limitation of Liability. NO PARTY SHALL HAVE ANY LIABILITY
WITH RESPECT TO ITS OBLIGATIONS UNDER THIS AGREEMENT OR OTHERWISE FOR
CONSEQUENTIAL, EXEMPLARY, INCIDENTAL OR PUNITIVE DAMAGES EVEN IF IT HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

         THE FOREGOING LIMITATION OF LIABILITY IS AN EXPRESSLY BARGAINED FOR
PORTION OF THE CONSIDERATION FOR THE PARTIES TO ENTER INTO THIS AGREEMENT.

                                  ARTICLE VIII

                            MISCELLANEOUS PROVISIONS

                  8.1 Amendment and Modifications. This Agreement may be
amended, modified and supplemented only by written agreement between the parties
hereto which states that it is intended to be a modification of this Agreement.

                  8.2 Waiver of Compliance. Any failure of the Company or
Purchasers to comply with any obligation, covenant, agreement or condition
herein may be expressly waived in writing by the other party, but such waiver or
failure to insist upon strict compliance with such obligation, covenant,
agreement or condition shall not operate as a waiver of, or estoppel with
respect to, any subsequent or other failure.

                  8.3 Expenses. Unless otherwise agreed to in writing or as set
forth in Schedule 3.6 of the Company Disclosure Schedule, the parties agree that
all fees and expenses incurred by them in connection with this Agreement and the
transactions contemplated hereby shall be borne by the party incurring such fees
and expenses, including, without limitation, all fees of counsel, actuaries and
accountants.

                  8.4 Remedies Waiver. All rights and remedies existing under
this Agreement are cumulative to and not exclusive of, any rights or remedies
otherwise available under applicable law. No failure on the part of any party to
exercise or delay in exercising any right hereunder shall be deemed a waiver
thereof, nor shall any single or partial exercise preclude any further or other
exercise of such or any other right. No right or remedy of a party shall be
deemed waived unless expressly made a term, covenant or condition in this
Agreement.
