     THIS STOCK PURCHASE AGREEMENT is made as of the ____ day of ________ 2000,

     WHEREAS, the Investor has indicated a desire to purchase shares of Common
Stock, $0.001 par value (the "Common Stock") from the Company at the price per
share set forth in Section 1.2 below.

     WHEREAS, the Company has indicated a desire to sell shares of Common Stock
to the Investor at the price per share set forth in Section 1.2 below.

     WHEREAS, the Company and the Investor have agreed that this Agreement shall
constitute the entire understanding and agreement between the parties with
regard to the subject matter hereof.

     NOW, THEREFORE, THE PARTIES HEREBY AGREE AS FOLLOWS:

     1.  Purchase and Sale of Stock.
         --------------------------

         1.1  Sale and Issuance of Stock.  Subject to the terms and conditions
              --------------------------
     of this Agreement, the Company agrees to sell to the Investor and the
     Investor agrees to purchase from the Company at the price per share set
     forth in Section 1.2 below such number of shares of the Company's Common
     Stock (the "Stock") as is equal to $2 million of shares of Common Stock at
     the price per share set forth in Section 1.2 below.

         1.2  The Closing.  The purchase and sale of the Stock shall be held at

     initial public offering (the "IPO") assuming that each of the conditions

     for the Stock shall be equal to the per share price paid by the public for

     thereafter).

     laws of general application relating to bankruptcy, insolvency and the
     relief of debtors and by general principles of equity.

         2.3  Valid Issuance of Stock.  The Stock, when issued, sold and
              -----------------------
     delivered in accordance with the terms hereof for the consideration

     investigations pending or, to the best of Company's knowledge, any basis
     therefor or threat thereof, against or affecting the Company, that, either

     change in the business, financial condition, or results of operations of
     the Company.

         2.5  Properties.  To the Company's knowledge (but without having

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

     or agreement to which the Company is now a party, except where such
     conflict, breach or default of any such contract or agreement, either
     individually or in the aggregate, would not have a material adverse effect

     operations or on the transactions contemplated by this Agreement.

     accounting principles applied on a consistent basis.  The Company has no
     material liabilities or obligations which are not shown or provided for in
     the Financial Statements, except liabilities or obligations after December
     31, 1999 in the ordinary course of business which, individually or in the
     aggregate, would not be reasonably likely to have a material adverse effect
     upon the business, operations or financial condition of the Company.

         6.1  Agreement Not to Transfer.
              -------------------------

              (a) Prior to the first anniversary of the Closing, the Investor
         shall not, directly or indirectly, Transfer or offer to Transfer any
         shares of the Stock other than to affiliates who agree to be bound by
         the terms of this Agreement, unless the Company consents to such
         Transfer and the transferee agrees to be bound by this Agreement. Any
         such Transfer must comply with all applicable laws, and the Company may
         require an opinion of counsel reasonably satisfactory to it as to such
         compliance. The restrictions set forth above are referred to as the
         "Transfer Restrictions."

              (b) In order to enforce the Transfer Restrictions, the Company
         may impose stop-transfer instructions with respect to the Stock until
         the end of the restricted period.

              (c) As used in this Agreement, the term "Transfer" shall mean any
         sale, transfer, assignment, hypothecation, encumbrance or other
         disposition, whether voluntary or involuntary, of shares of the Stock.
         In the case of a hypothecation, the Transfer shall be deemed to occur
         both at the time of the initial pledge and at any pledgee's sale or a
         sale by any secured creditor or a retention by the secured creditor of
         the pledged shares of the Stock in complete or partial satisfaction of
         the indebtedness for which the shares of the Stock are security.

              (d) After the first anniversary of the Closing, the Investor may
         Transfer shares of the Stock without the transferee agreeing to be
         bound by this Agreement and without the consent of the Company,
         provided such Transfer complies with applicable federal and state
         securities laws.

         6.2  Market Stand-Off.  In addition to the Transfer Restrictions
              ----------------
     (which shall in no way be limited by the following), in connection with any
     underwritten public offering by the Company of its equity securities
     pursuant to an effective registration statement filed under the Securities
     Act, the Investor shall not Transfer or offer to Transfer any shares of the
     Stock without the prior written consent of the Company and its
     underwriters.  Such restriction (the "Market Stand-Off") shall be in effect
     for such period of time from and after the effective date of the final
     prospectus for the offering as may be requested by the Company or such
     underwriters; provided, however, that (i) such Market Stand-Off shall not
     exceed one hundred eighty (180) days, and (ii) the Investor shall be
     subject to the Market Stand-Off only if the officers and directors of the
     Company are also subject to similar restrictions.  In order to enforce the
     Market Stand-Off, the Company may impose stop-transfer instructions with
     respect to the Stock until the end of the applicable stand-off period.

         6.3  Voting Agreements.  The following provision will be applicable at
              -----------------
     any time the Investor owns or controls in excess of 9.5% of the Voting
     Securities (as defined below) during the first five (5) years after the
     Closing: In the event that the Board of Directors of the Company approves a
     sale of substantially all of the assets or capital stock of the Company or
     a merger in which the Company would not be the surviving corporation, the
     Investor agrees to vote all shares of Voting Securities owned by it with
     respect to such sale of substantially all of the assets or capital stock or
     merger in the same proportion as the votes cast

                                      -4-
<PAGE>

     by all other stockholders of the Company entitled to vote on such matter
     (other than the Investor) at such time as such matter is presented for a
     vote of the stockholders of the Company. The Investor, as a holder of
     Voting Securities, shall be present, in person or by proxy, at all meetings
     of stockholders of the Company so that all shares of Voting Securities
     beneficially owned by it may be counted for the purpose of determining the
     presence of a quorum at such meetings. For purposes of this Agreement, (i)
     the term "Voting Securities" shall refer to all securities of the Company
     entitled to vote generally for the election of directors, and (ii) the term
     "beneficial ownership" shall have the meaning set forth in Rule 13d-3 under
     the Securities Exchange Act of 1934, as amended (the "Exchange Act").

         6.4  Investor Rights Agreement.  Concurrently with the execution of
              -------------------------
     this Agreement, the parties shall enter into the Investor Rights Agreement
     attached hereto as Exhibit A.

corporation (the "Company") Delphi Automotive (the "Investor").
                  -------                           --------

                                    RECITALS
                                    --------

     WHEREAS, the Company and the Investor are entering into a Stock Purchase
Agreement (the "Purchase Agreement") of even date herewith; and
                ------------------

     WHEREAS, in order to induce the Investor to purchase shares of Common Stock
pursuant to the Purchase Agreement, the Company desires to grant certain
registration rights to the Investor as set forth herein.

     NOW, THEREFORE, THE PARTIES HEREBY AGREE AS FOLLOWS:

     1.  Registration Rights.  The Company covenants and agrees as follows:
         -------------------

         1.1  Definitions.  For purposes of this Section 1:

"affiliate" (as defined in Rule 12b-2 of the General Rules and Regulations under
the Securities Exchange Act of 1934, as amended).

              (c) The term "Holder" means the Investor or any permitted assignee
                            ------
of the registration rights with respect to the Registrable Securities pursuant

              (d) The term "1934 Act" shall mean the Securities Exchange Act of

              (e) The term "person" means any individual, firm, corporation,
                            ------
partnership, trust, incorporated or unincorporated association, joint venture,
joint stock company, limited liability company, government (or any agency or
political subdivision thereof) or other entity of any kind, and shall include
any successor (by merger or otherwise) of such entity.

              (f) The terms "register", "registered" and "registration" refer
                             --------    ----------       ------------
to a registration effected by preparing and filing a registration statement or
similar document in compliance with the Act, and the declaration or ordering of
effectiveness of such registration statement or document.

              (g) The term "Registrable Securities" means Common Stock issued
                            ----------------------

right or other security which is issued as) a dividend or other distribution
with respect to, or in exchange for or in replacement of, the foregoing,
excluding, however, any shares sold or transferred by a person in a transaction
in which the rights under this Section 1 are not assigned. Registrable
Securities shall also include all securities defined as "Registrable Securities"

Securities.

         1.2  Piggyback Registration Rights.
              -----------------------------

              (a) Registration Rights.  At any time after January 31, 2001, if
                  -------------------
the Company proposes to register any of its stock or other securities under the
Act in connection with the public offering of such securities solely for cash
(other than a registration relating solely to the sale of securities to
participants in a Company stock plan, a registration effected pursuant to Rule
145 under the Act, or a registration on any form which does not include
substantially the same information as would be required to be included in a
registration statement covering the sale of the Registrable Securities) the
Company shall, at such time, promptly give each Holder written notice of such
registration. Upon the written request of each Holder given within fifteen (15)
days after mailing of such notice by the Company in accordance with Section 7 of
the Purchase Agreement, the Company shall, subject to the provisions of
paragraph (b) below, cause to be registered under the Act all of the Registrable
Securities that each such Holder has requested to be registered.

              (b) Underwriting.  If the registration of which the Company gives
                  ------------
notice is for a registered public offering involving an underwriting, the
Company shall so advise the Holders as part of the written notice given pursuant
to Section 1.2(a).  In such event, the right of any Holder to registration
pursuant to this Section 1.2 shall be conditioned upon such Holder's
participation in such underwriting and the inclusion of Registrable Securities
in the underwriting to the extent provided herein.  All Holders proposing to
distribute their securities through such underwriting shall (together with the
Company and the other holders distributing their securities through such
underwriting) enter into an underwriting agreement in customary form with the
managing underwriter selected for such underwriting by the Company.
Notwithstanding any other provision of this Section 1.2, if the Company and the
managing underwriter determine that marketing factors require a limitation of
the number of shares to be underwritten, the managing underwriter may limit or
exclude entirely the Registrable Securities to be included in such registration.
The Company shall so advise all Holders distributing their securities through
such underwriting, and the number of shares of Registrable Securities and other
securities that may be included in the registration and underwriting on behalf
of persons other than the Company shall be allocated among all Holders and such
other holders in proportion, as nearly as practicable, to the respective amounts
of Registrable Securities and other securities entitled to registration rights
held by such Holders and other holders at the time of filing the registration
statement.  To facilitate the allocation of shares in accordance with the above
provisions, the Company may round the number of shares allocated to any Holder
or other holder to the nearest 100 shares.

         1.3  Furnish Information.  It shall be a condition precedent to the
              -------------------
obligations of the Company to take any action pursuant to this Section 1 with
respect to the Registrable Securities of any selling Holder that such Holder
shall furnish to the Company such information regarding itself, the Registrable
Securities held by it, and the intended method of disposition of such securities
as shall be required to effect the registration of such Holder's Registrable
Securities.

         1.4  Expenses of Registration.  The Company shall bear and pay all
              ------------------------
expenses incurred in connection with any registration, filing (including keeping
such filings effective) or qualification of Registrable Securities with respect
to the registrations pursuant to this Agreement, including (without limitation)
all registration, filing, and qualification fees, printers and accounting fees
relating or apportionable thereto and the fees and disbursements of counsel for
the Company and no more than one counsel for all the selling Holders, but
excluding underwriting discounts and commissions relating to Registrable
Securities.

         1.5  No Delay of Registration.  No Holder shall have any right to
              ------------------------
obtain or seek an injunction restraining or otherwise delaying any such
registration as the result of any controversy that might arise with respect to
the interpretation or implementation of this Section 1.

         1.6  Indemnification.  In the event any Registrable Securities are
               --------------
included in a registration statement under this Section 1:

                                      -2-
<PAGE>

              (a) To the extent permitted by law, the Company will indemnify and
hold harmless each Holder, any underwriter (as defined in the Act) for such
Holder and each person, if any, who controls such Holder or underwriter within
the meaning of the Act or the 1934 Act, against any losses, claims, damages, or
liabilities (joint or several) to which they may become subject under the Act,
the 1934 Act or other federal or state law, insofar as such losses, claims,
damages, or liabilities (or actions in respect thereof) arise out of or are
based upon any of the following statements, omissions or violations
(collectively a "Violation"):  (i) any untrue statement or alleged untrue
                 ---------
statement of a material fact contained in such registration statement, including
any preliminary prospectus or final prospectus contained therein or any
amendments or supplements thereto, (ii) the omission or alleged omission to
state therein a material fact required to be stated therein, or necessary to
make the statements therein not misleading, or (iii) any violation or alleged
violation by the Company of the Act, the 1934 Act, any state securities law or
any rule or regulation promulgated under the Act, the 1934 Act or any state
securities law; and the Company will pay to each such Holder, underwriter or
controlling person any legal or other expenses reasonably incurred by them in
connection with investigating or defending any such loss, claim, damage,
liability, or action, as such expenses are incurred; provided, however, that the
indemnity agreement contained in this subsection 1.6(a) shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability, or action
if such settlement is effected without the consent of the Company (which consent
shall not be unreasonably withheld), nor shall the Company be liable to any
indemnitee for any such loss, claim, damage, liability, or action to the extent
that it arises out of or is based upon a Violation which occurs in reliance upon
and in conformity with written information furnished by such indemnitee.

              (b) To the extent permitted by law, each Holder will indemnify and
hold harmless the Company, each of its directors, each of its officers who has
signed the registration statement, each person, if any, who controls the Company
within the meaning of the Act, any underwriter, any other Holder selling
securities in such registration statement and any controlling person of any such
underwriter or other Holder, severally but not jointly, against any losses,
claims, damages, or liabilities (joint or several) to which any of the foregoing
persons may become subject, under the Act, the 1934 Act or other federal or
state law, insofar as such losses, claims, damages, or liabilities (or actions
in respect thereto) arise out of or are based upon any Violation, in each case
to the extent (and only to the extent) that such Violation occurs in reliance
upon and in conformity with written information furnished by such Holder; and
each such Holder will pay any legal or other expenses reasonably incurred by any
person intended to be indemnified pursuant to this subsection 1.6(b), in
connection with investigating or defending any such loss, claim, damage,
liability, or action; provided, however, that the indemnity agreement contained
in this subsection 1.6(b) shall not apply to amounts paid in settlement of any
such loss, claim, damage, liability or action if such settlement is effected
without the consent of the Holder, which consent shall not be unreasonably
withheld; provided that in no event shall any indemnity by any Holder under this
subsection 1.6(b) exceed the gross proceeds from the offering received by such
Holder.

              (c) Promptly after receipt by an indemnified party under this
Section 1.6 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 1.6, deliver to
the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with one counsel mutually
satisfactory to the parties; provided, however, that an indemnified party
(together with all other indemnified parties which may be represented without
conflict by one counsel) shall have the right to retain one separate counsel,
with the fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action shall not relieve such indemnifying party of any liability to the
indemnified party under this Section 1.6 unless the failure to deliver notice is
materially prejudicial to its ability to defend such action. Any omission to so
deliver written notice to the indemnifying party will not relieve it of any
liability that it may have to any indemnified party otherwise than under this
Section 1.6.

              (d) If the indemnification provided for in this Section 1.6 is
held by a court of competent jurisdiction to be unavailable to an indemnified
party with respect to any loss, liability, claim, damage, or expense referred to
therein, then the indemnifying party, in lieu of indemnifying such indemnified
party hereunder,

                                      -3-
<PAGE>

shall contribute to the amount paid or payable by such indemnified party as a
result of such loss, liability, claim, damage, or expense in such proportion as
is appropriate to reflect the relative fault of the indemnifying party on the
one hand and of the indemnified party on the other in connection with the
statements or omissions that resulted in such loss, liability, claim, damage, or
expense as well as any other relevant equitable considerations; provided that in
no event shall any Holder be required to contribute under this subsection 1.6(d)
an aggregate amount in excess of the gross proceeds from the offering received
by such Holder less any amounts paid by the Holder pursuant to subsection
1.6(b). The relative fault of the indemnifying party and of the indemnified
party shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission to state a
material fact relates to information supplied by the indemnifying party or by
the indemnified party and the parties' relative intent, knowledge, access to
information, and opportunity to correct or prevent such statement or omission.

              (e) Notwithstanding the foregoing, to the extent that the
provisions on indemnification and contribution contained in the underwriting
agreement entered into in connection with the underwritten public offering are
in conflict with the foregoing provisions, the provisions in the underwriting
agreement shall control.

              (f) The obligations of the Company and Holders under this Section
1.6 shall survive the completion of any offering of Registrable Securities in a
registration statement under this Section 1, and otherwise.

         1.7  Reports under Securities Exchange Act of 1934.  With a view to
              ---------------------------------------------
making available to the Holders the benefits of Rule 144 promulgated under the
Act and any other rule or regulation of the SEC that may at any time permit a
Holder to sell securities of the Company to the public without registration, the
Company agrees to:

              (a) make and keep public information available, as those terms are
understood and defined in SEC Rule 144, at all times after ninety (90) days
after the effective date of the first registration statement filed by the
Company for the offering of its securities to the general public;

              (b) file with the SEC in a timely manner all reports and other
documents required of the Company under the Act and the 1934 Act; and

              (c) furnish to any Holder, so long as the Holder owns any
Registrable Securities, forthwith upon request (i) a written statement by the
Company that it has complied with the reporting requirements of SEC Rule 144 (at
any time after ninety (90) days after the effective date of the first
registration statement filed by the Company), the Act and the 1934 Act (at any
time after it has become subject to such reporting requirements), (ii) a copy of
the most recent annual or quarterly report of the Company and such other reports
and documents so filed by the Company, and (iii) such other information as may
be reasonably requested in availing any Holder of any rule or regulation of the
SEC which permits the selling of any such securities without registration.

         1.8  Assignment of Registration Rights.  The rights to cause the
              ---------------------------------
Company to register Registrable Securities pursuant to this Section 1 may be
assigned (but only with all related obligations) by a Holder to a transferee or
assignee of such securities who, after such assignment or transfer, holds at
least one hundred thousand (100,000) shares of Registrable Securities (subject
to appropriate adjustment for stock splits, dividends, combinations and other
recapitalizations), provided:  (a) the Company is, within a reasonable time
before such transfer, furnished with written notice of the name and address of
such transferee or assignee and the securities with respect to which such
registration rights are being assigned; (b) such transferee or assignee agrees
in writing to be bound by and subject to the terms and conditions of this
Agreement, including without limitation the provisions of Section 1.9 below; and
(c) such assignment shall be effective only if immediately following such
transfer the further disposition of such securities by the transferee or
assignee is restricted under the Act.  For the purposes of determining the
number of shares of Registrable Securities held by a transferee or assignee of a
holder of Registrable Securities, Affiliated Persons shall be aggregated
together, provided that all assignees and transferees who would not qualify
individually for assignment of registration rights shall designate in writing to
the Company from time to time

                                      -4-
<PAGE>

a single attorney-in-fact on behalf of the entire group of Affiliated Persons
for the purpose of exercising any rights, receiving notices or taking any action
under this Section 1.

         1.9  "Market Stand-Off" Agreement. The Investor shall be bound by
              ----------------------------
the transfer restrictions and market standoff provisions set forth in the
Purchase Agreement to the extent, but only to the extent, set forth in the
Purchase Agreement.  In addition:

              (a) Each Holder other than the Investor hereby agrees that, during
the period of duration specified by the Company and an underwriter of common
stock or other securities of the Company, following the effective date of a
registration statement of the Company filed under the Act, it shall not, to the
extent requested by the Company and such underwriter, directly or indirectly
sell, offer to sell, contract to sell (including, without limitation, any short
sale), grant any option to purchase or otherwise transfer or dispose of (other
than to donees who agree to be similarly bound) any securities of the Company
held by it as of the effective date except common stock included in such
registration; provided, however, that:

                  (i) all officers and directors of the Company enter into
similar agreements; and

                  (ii) such market stand-off time period shall not exceed one
hundred eighty (180) days without the consent of the affected Holder; and

              (b) Each Holder other than the Investor agrees to provide to the
other Underwriters of any public offering such further agreement as such
Underwriter may require in connection with this market stand-off agreement. In
order to enforce the foregoing covenant, the Company may impose stop-transfer
instructions with respect to the Registrable Securities of each Holder (and the
shares or securities of every other person subject to the foregoing restriction)
until the end of such period.

         1.10 Termination of Registration Rights.  The right of any Holder
              ----------------------------------
to inclusion in any registration pursuant to Section 1.2 shall terminate upon
such date as, in the opinion of counsel to the Company,  a public trading market
shall exist for the Company's Common Stock and all shares of Registrable
Securities beneficially owned or subject to Rule 144 aggregation by such Holder
may immediately be sold under Rule 144 (without regard to Rule 144(k)) during
any 90-day period and such Holder holds less than one percent (1%) of the
outstanding capital stock of the Company.

     2.  Securities Law Compliance.
         -------------------------

         2.1  Restrictions on Transferability. The Registrable Securities and
              -------------------------------
any other securities issued with respect of the Registrable Securities upon any
stock split, stock dividend, recapitalization, merger, consolidation, or similar
event, shall not be sold, assigned, transferred or pledged except upon the
conditions specified in the Purchase Agreement and this Agreement, which
conditions are intended to ensure compliance with the provisions of the Act, or
otherwise in compliance with the Act.  In any sale, transfer, assignment or
pledge of any such shares prior to the first anniversary of the Closing (as
defined in the Purchase Agreement) other than in a public offering, the Investor
will cause any proposed purchaser, assignee, transferee, or pledgee of such
shares held by the Investor to agree to take and hold such securities subject to
the provisions and upon the conditions specified in the Purchase Agreement and
this Agreement, unless otherwise consented to by the Company.

         2.2  Further Limitations on Disposition.  Without in any way
              ----------------------------------
limiting the above, the Investor further agrees not to make any disposition of
all or any portion of the Registrable Securities unless and until the transferee
has agreed in writing for the benefit of the Company to be bound by Sections 1.9
of this Agreement and (to the extent required by applicable securities law, in
the opinion of counsel to the Company) has agreed to be bound by these Sections
2.1 and 2.2; provided, however, that the foregoing shall not apply if:

              (a) There is then in effect a Registration Statement under the Act
covering such proposed disposition and such disposition is made in accordance
with such Registration Statement; or

                                      -5-
<PAGE>

              (b) (i) The Investor shall have notified the Company of the
proposed disposition and shall have furnished the Company with a detailed
statement of the circumstances surrounding the proposed disposition, and (ii)
until such time as the proposed disposition may be made under Rule 144(k) under
the 1934 Act, if reasonably requested by the Company, the Investor shall have
furnished the Company with an opinion of counsel, reasonably satisfactory to the
Company, that such disposition will not require registration of such shares
under the Act; or

              (c) The proposed disposition is made under Rule 144(k).

         2.3  Notwithstanding anything to the contrary contained herein, the
shares of stock acquired by the Investor from the Company pursuant to the
Purchase Agreement (and any other securities issued with respect to such
securities upon any stock split, stock dividend, recapitalization, merger,
consolidation or similar event) may be sold, assigned, transferred or pledged by
Investor to any person and such person shall not be required to take and hold
such securities subject to the Purchase Agreement, this Agreement or any of the
provisions hereof or thereof, so long as the transaction is at least one year
after the Closing (as defined in the Purchase Agreement), complies with
applicable federal and state securities laws, and Investor is not transferring
to such person the registration rights set forth in Section 1 hereof.

     3.  Miscellaneous.  Section 7 of the Purchase Agreement is hereby
         -------------
incorporated by reference as though restated in full herein and applied to this
Agreement.

                                      -6-
