                            STOCK PURCHASE WARRANT
                            ----------------------

Date of Issuance:   March 14, 2001          Certificate No. W-1

          For value received, DELCO REMY INTERNATIONAL, INC., a Delaware
corporation (the "Company"), hereby grants to WORLD EQUITY PARTNERS, L.P., a
Delaware limited partnership ("WEP"), or its transferees and assigns, the right
to purchase from the Company (i) a total of 156,574.31 Common Warrant Shares (as
defined herein) at a price per share of $.00119 (the "Initial Common Exercise
Price") and (ii) a total of 144,725.44 Preferred Warrant Shares (as defined
herein, and together with the Common Warrant Shares, the "Warrant Shares") at a
price per share of $.01253 (the "Initial Preferred Exercise Price").  The
exercise prices and number of Warrant Shares (and the amount and kind of other
securities) for which this Warrant is exercisable shall be subject to adjustment
as provided herein. Certain capitalized terms used herein are defined in Section
5 hereof.

          This Warrant is subject to the following provisions:

     SECTION 1.  Exercise of Warrant.
                 -------------------

          A.     Exercise Period.  The purchase rights represented by this
                 ---------------
Warrant may be exercised, in whole or in part, at any time and from time to time
after the date hereof to and
<PAGE>

including 5:00 p.m., New York City time, on July 31, 2004 or, if such day is not
a business day, on the next preceding business day (the "Exercise Period").

          B.   Mandatory Exercise Ratio.  This Warrant may be exercised at any
               ------------------------
time and from time to time during the Exercise Period for Preferred Warrant
Shares without also being exercised for Common Warrant Shares. This Warrant may
only be exercised at any time and from time to time during the Exercise Period
for the number of Common Warrant Shares such that the "Common/Preferred Exercise
Ratio" at the time of such exercise is equal to or less than the "Initial
Ratio". The "Initial Ratio" is a fraction, (i) the numerator of which is the
number of Common Warrant Shares this Warrant is exercisable for on the date
hereof and (ii) the denominator of which is the number of Preferred Warrant
Shares this Warrant is exercisable for on the date hereof (in each case as such
Common Warrant Shares or Preferred Warrant Shares are adjusted pursuant to the
terms hereof including Sections 2 and 3B(ii)). The "Common/Preferred Exercise
Ratio" is a fraction, (i) the numerator of which is the number of Common Warrant
Shares which will have been exercised (after giving effect to the number of
                                       -----
Common Warrant Shares to be exercised at such time and previously) and (ii) the
denominator of which is the number of Preferred Warrant Shares which will have
been exercised (after giving effect to the number of Preferred Warrant Shares to
                -----
be exercised at such time and previously).

          C.   Exercise Procedure.
               ------------------

               (i)  This Warrant shall be deemed to have been exercised when all
of the following items have been delivered to the Company (the "Exercise Time"):

                    (a)  a completed Exercise Agreement, as described in section
     1D below, executed by the Person exercising all or part of the purchase
     rights represented by this Warrant (the "Purchaser");

                    (b)  this Warrant;

                    (c)  if the Purchaser is not the Registered Holder, an
     Assignment or Assignments in the form set forth in Exhibit II hereto
                                                        ----------
     evidencing the assignment of this Warrant to the Purchaser; and

                    (d)  either (x) a check payable to the Company in an amount
     equal to the sum of (i) the product of the Common Exercise Price multiplied
     by the number of Common Warrant Shares and (ii) the product of the
     Preferred Exercise Price multiplied by the number of Preferred Warrant
     Shares, in each case being purchased upon such exercise (the "Aggregate
     Exercise Price"), (y) the surrender to the Company of securities of the
     Company having a value equal to the Aggregate Exercise Price of the Warrant
     Shares being purchased upon such exercise (which value in the case of debt
     securities shall be the principal amount thereof, in the case of shares of
     Common Stock shall be the Fair Market Value thereof and in the case of
     shares of Series A Preferred Stock shall be the Series A Issue Price (as
     hereinafter defined), plus any accrued and unpaid dividends), or (z) the
     delivery of a notice to the Company that the Purchaser is

                                       2
<PAGE>

     exercising the Warrant by authorizing the Company to reduce the number of
     Warrant Shares subject to the Warrant by (i) the number of shares Common
     Stock having an aggregate Fair Market Value and (ii) the number of shares
     of Series A Preferred Stock having a Series A Issue Price which,
     collectively, equal the Aggregate Exercise Price. Any reduction pursuant to
     clause (z) above shall be in the same ratio of Common Warrant Shares to
     Preferred Warrant Shares as the Common/Preferred Exercise Ratio.

               (ii)    Certificates for Warrant Shares purchased upon exercise
of this Warrant shall be delivered by the Company to the Purchaser within five
days after the date of the Exercise Time together with any cash payable in lieu
of a fraction of a share pursuant to Section 14 hereof. Unless this Warrant has
expired or all of the purchase rights represented hereby have been exercised,
the Company shall prepare a new Warrant, substantially identical hereto,
representing the rights formerly represented by this Warrant which have not
expired or been exercised and shall, within such five-day period, deliver such
new Warrant to the Person designated for delivery in the Exercise Agreement.

               (iii)   The Warrant Shares issuable upon the exercise of this
Warrant shall be deemed to have been issued to the Purchaser at the Exercise
Time, and the Purchaser shall be deemed for all purposes to have become the
record holder of such Warrant Shares at the Exercise Time.

               (iv)    The issuance of certificates for Warrant Shares upon
exercise of this Warrant shall be made without charge to the Registered Holder
or the Purchaser for any issuance tax in respect thereof or other cost incurred
by the Company in connection with such exercise and the related issuance of
Warrant Shares;

provided, however, that the Company shall not be required to pay any taxes in
respect of the Warrant or Warrant Shares, with respect to any transfer of the
Warrant, which taxes shall be paid by the transferee prior to the issuance of
such Warrant Shares.

               (v)     The Company shall not close its books against the
transfer of this Warrant or of any Warrant Shares issued or issuable upon the
exercise of this Warrant in any manner which interferes with the timely exercise
of this Warrant. In the event that the par value per share of the unissued
Warrant Shares acquirable upon exercise of this Warrant is less than the
Exercise Prices then in effect, the Purchaser shall purchase Warrant Shares
hereunder at par value, and the Company shall be obligated to reimburse the
Purchaser for the aggregate amount of consideration paid in connection with such
exercise in excess of the Exercise Prices then in effect.

               (vi)    The Company shall assist and cooperate with the
Registered Holder or any Purchaser required to make any governmental filings or
obtain any governmental approvals prior to or in connection with any exercise of
this Warrant.

               (vii)   Notwithstanding any other provision hereof, if an
exercise of any portion of this Warrant is to be made in connection with a
public offering or a sale of the

                                       3
<PAGE>

Company (pursuant to a merger, sale of stock or otherwise), such exercise may at
the election of the holder be conditioned upon the consummation of such
transaction, in which case such exercise shall not be deemed to be effective
until immediately prior to the consummation of such transaction.

               (viii)  The Company shall at all times reserve and keep available
out of its authorized but unissued Warrant Shares solely for the purpose of
issuance upon the exercise of this Warrant, the maximum number of Warrant Shares
issuable upon the exercise of this Warrant. All Warrant Shares which are so
issuable shall, when issued and upon the payment of the applicable Exercise
Price, be duly and validly issued, fully paid and nonassessable and free from
all liens and charges. The Company shall take all such actions as may be
necessary to ensure that all such Warrant Shares may be so issued without
violation by the Company of any applicable law or governmental regulation or any
requirements of any domestic securities exchange upon which shares of Common
Stock or other securities constituting Warrant Shares may be listed (except for
official notice of issuance which shall be immediately delivered by the Company
upon each such issuance). The Company will use its best efforts to cause the
Common Warrant Shares, immediately upon such exercise, to be listed on any
domestic securities exchange upon which like shares of Common Stock or other
securities constituting Common Warrant Shares are listed at the time of such
exercise.

               (ix)    If the Warrant Shares issuable by reason of exercise of
this Warrant are convertible into or exchangeable for any other stock or
securities of the Company, the Company shall, at the Purchaser's option and upon
surrender of this Warrant by such Purchaser as provided above together with any
notice, statement or payment required to effect such conversion or exchange of
Warrant Shares, deliver to such Purchaser (or as otherwise specified by such
Purchaser) a certificate or certificates representing the stock or securities
into which the Warrant Shares issuable by reason of such conversion are
convertible or exchangeable, registered in such name or names and in such
denomination or denominations as such Purchaser has specified.

               (x)     The Company shall at all times in good faith assist in
the carrying out of all terms of this Warrant. Without limiting the generality
of the foregoing, the Company shall (a) use its best efforts to obtain all such
authorizations, exemptions or consents from any public regulatory body having
jurisdiction thereof as may be necessary to enable the Company to perform its
obligations under this Warrant and (b) not undertake any reverse stock split,
combination, reorganization or other reclassification of its capital stock which
would have the effect of making this Warrant exercisable for less than one share
of Common Stock or less than one share of Series A Preferred Stock.

               (xi)    No stockholder of the Company has or shall have any
preemptive right to subscribe for the Warrant Shares issuable pursuant hereto.

          D.   Exercise Agreement.  Upon any exercise of this Warrant, the
               ------------------
Purchaser shall deliver to the Company an Exercise Agreement in substantially
the form set forth in Exhibit I hereto, except that if the Warrant Shares are
                      ---------
not to be in the name of the Registered

                                       4
<PAGE>

Holder, the Exercise Agreement shall also state the name of the Person to whom
the certificates for the Warrant Shares are to be issued, and if the number of
Warrant Shares to be issued does not include all of the Warrant Shares
purchasable hereunder, it shall also state the name of the Person to whom a new
Warrant for the unexercised portion of the rights hereunder is to be issued.

     SECTION 2.  Adjustment of Exercise Price and Number of Shares.  In order to
                 -------------------------------------------------
prevent dilution of the rights granted under this Warrant, the Initial Common
Exercise Price and the Initial Preferred Exercise Price shall be subject to
adjustment from time to time as provided in this Section 2 (as so adjusted, the
"Common Exercise Price" and the "Preferred Exercise Price", as applicable, and
collectively sometimes referred to herein as the "Exercise Prices"), and the
number of Common Warrant Shares and Preferred Warrant Shares obtainable upon
exercise of this Warrant shall be subject to adjustment from time to time, each
as provided in this Section 2; provided, however, that there shall be no
Adjustment to the Exercise Prices or to the number of Warrant Shares acquirable
upon exercise of the Warrant, as provided in this Section 2 (an "Adjustment"),
(i) for any issuance which results in the distribution of Purchase Rights
pursuant to Section 4 hereof or (ii) unless and until such Adjustment, together
with any previous Adjustments to the Exercise Prices or to the number of Warrant
Shares so acquirable which would otherwise have resulted in an Adjustment were
it not for this proviso, would require an increase or decrease of at least 1% of
the total number of Warrant Shares so acquirable at the time of such Adjustment,
in which event such Adjustment and all such previous Adjustments shall
immediately occur.

          A.   Adjustment of Common Exercise Price and Number of Common Warrant
               ----------------------------------------------------------------
Shares upon Issuance of Common Stock.  If and whenever, on or after the date
------------------------------------
hereof, the Company issues or sells, or in accordance with Section 2B is deemed
to have issued or sold, other than pursuant to (i) a Permitted Issuance, (ii) as
described in Section 2C or (iii) the Securities Agreement, any shares of Common
Stock for a consideration per share less than the Fair Market Value per share of
the Common Stock, determined as of the date of such issuance or sale, then
immediately upon such issuance or sale the Common Exercise Price shall be
reduced to equal the amount determined by multiplying the Common Exercise Price
in effect immediately prior to such issuance or sale by a fraction, the
numerator of which will be the sum of (1) the number of shares of Common Stock
Deemed Outstanding immediately prior to such issuance or sale multiplied by the
Fair Market Value per share of the Common Stock determined as of the date of
such issuance or sale, plus (2) the consideration, if any, received by the
Company upon such issuance or sale, and the denominator of which will be the
product derived by multiplying such Fair Market Value per share of the Common
Stock by the number of shares of Common Stock Deemed Outstanding immediately
after such issuance or sale. Upon each such adjustment of the Common Exercise
Price hereunder, the number of Common Warrant Shares acquirable upon exercise of
this Warrant shall be adjusted to equal the number of shares determined by
multiplying the Common Exercise Price in effect immediately prior to such
adjustment by the number of Common Warrant Shares acquirable upon exercise of
this Warrant immediately prior to such adjustment and dividing the product
thereof by the Common Exercise Price resulting from such adjustment.

                                       5
<PAGE>

          B.   Effect on Exercise Price of Certain Events.  For purposes of
               ------------------------------------------
determining the adjusted Common Exercise Price under Section 2A, the following
shall be applicable:

               (i)  Issuance of Rights or Options.  If the Company in any
                    ------------------------------
manner grants any rights or options (other than Purchase Rights covered by
Section 4 hereof or a Permitted Issuance) to subscribe for or to purchase Common
Stock or any stock or other securities convertible into or exchangeable for
Common Stock (including without limitation convertible common stock) (such
rights or options being herein called "Options" and such convertible or
exchangeable stock or securities being herein called "Convertible Securities")
and the price per share for which Common Stock is issuable upon the exercise of
such Options or upon conversion or exchange of such Convertible Securities is
less than the Fair Market Value per share of the Common Stock then in effect,
then the total maximum number of shares of Common Stock issuable upon the
exercise of such Options or upon conversion or exchange of the total maximum
amount of such Convertible Securities issuable upon the exercise of such Options
shall be deemed to be outstanding and to have been issued and sold by the
Company for such price per share. For purposes of this paragraph, the "price per
share for which Common Stock is issuable upon exercise of such Options or upon
conversion or exchange of such Convertible Securities" is determined by dividing
(A) the total amount, if any, received or receivable by the Company as
consideration for the granting of such Options, plus the minimum aggregate
amount of additional consideration payable to the Company upon the exercise of
all such Options, plus in the case of such Options which relate to Convertible
Securities, the minimum aggregate amount of additional consideration, if any,
payable to the Company upon the issuance or sale of such Convertible Securities
and the conversion or exchange thereof, by (B) the total maximum number of
shares of Common Stock issuable upon exercise of such Options or upon the
conversion or exchange of all such Convertible Securities issuable upon the
exercise of such Options. No further adjustment of the Common Exercise Price
shall be made upon the actual issuance of such Common Stock or of such
Convertible Securities upon the exercise of such Options or upon the actual
issuance of such Common Stock upon conversion or exchange of such Convertible
Securities.

               (ii) Issuance of Convertible Securities.  If the Company in any
                    ----------------------------------
manner issues or sells any Convertible Securities and the price per share for
which Common Stock is issuable upon such conversion or exchange is less than the
Fair Market Value per share of the Common Stock then in effect, then the maximum
number of shares of Common Stock issuable upon conversion or exchange of such
Convertible Securities shall be deemed to be outstanding and to have been issued
and sold by the Company for such price per share. For the purposes of this
paragraph, the "price per share for which Common Stock is issuable upon such
conversion or exchange" is determined by dividing (A) the total amount received
or receivable by the Company as consideration for the issue or sale of such
Convertible Securities, plus the minimum aggregate amount of additional
consideration, if any, payable to the Company upon the conversion or exchange
thereof, by (B) the total maximum number of shares of Common Stock issuable upon
the conversion or exchange of all such Convertible Securities. No further
adjustment of the Common Exercise Price shall be made upon the actual issue of
such Common Stock upon conversion or exchange of such Convertible Securities,
and if any such issue or sale of

                                       6
<PAGE>

such Convertible Securities is made upon exercise of any Options for which
adjustments of the Common Exercise Price have been or are to be made pursuant to
other provisions of this Section 2B, no further adjustment of the Common
Exercise Price shall be made by reason of such issue or sale.

               (iii)  Change in Option Price or Conversion Rate.  If either
                      -----------------------------------------
the purchase price provided for in any Options, the additional consideration, if
any, payable upon the issue, conversion or exchange of any Convertible
Securities, or the rate at which any Convertible Securities are convertible into
or exchangeable for Common Stock shall change at any time, the Common Exercise
Price in effect at the time of such change shall be adjusted to the Exercise
Price which would have been in effect at such time had such Options or
Convertible Securities still outstanding provided for such changed purchase
price, additional consideration or changed conversion rate, as the case may be,
at the time initially granted, issued or sold and the number of Common Warrant
Shares shall be correspondingly readjusted.

               (iv)   Treatment of Expired Options and Unexercised Convertible
                      --------------------------------------------------------
Securities. Upon the expiration of any Option or the termination of any right to
convert or exchange any Convertible Securities, in either case without the
exercise of such Option or right, the Common Exercise Price then in effect and
the number of Common Warrant Shares acquirable hereunder shall be adjusted to
the Common Exercise Price and the number of shares which would have been in
effect at the time of such expiration or termination had such Option or
Convertible Securities, to the extent outstanding immediately prior to such
expiration or termination, never been issued.

               (v)    Calculation of Consideration Received.  If any Common
                      -------------------------------------
Stock, Options or Convertible Securities are issued or sold or deemed to have
been issued or sold for cash, the consideration received therefor shall be
deemed to be the net amount received by the Company therefor. In case any Common
Stock, Options or Convertible Securities are issued or sold for a consideration
other than cash, the amount of the consideration other than cash received by the
Company shall be the fair value of such consideration, except where such
consideration consists of marketable securities, in which case the amount of
consideration received by the Company shall be the market price thereof as of
the date of receipt. In case any Common Stock, Options or Convertible Securities
are issued to the owners of the non-surviving entity in connection with any
merger or other business combination in which the Company is the surviving
entity, the amount of consideration therefor shall be deemed to be the fair
value of such portion of the net assets and business of the non-surviving entity
as is attributable to such Common Stock, Options or Convertible Securities, as
the case may be. The fair value of any consideration other than cash or
marketable securities shall be determined by the Company, unless such
consideration is paid by an Affiliate of the Company, in which case, the fair
value of such consideration shall be determined jointly by the Company and the
Required Holders. If such parties are unable to reach agreement within a
reasonable period of time, such fair value shall be determined by an appraiser
jointly selected by the Company and the Required Holders, whose determination
shall be final and binding on the Company and all holders of Warrants (as

                                       7
<PAGE>

defined in Section 8 below). The fees and expenses of such appraiser shall be
paid by the Company.

               (vi)   Integrated Transactions.  Other than Permitted Issuances,
                      -----------------------
in case any Option is issued in connection with the issue or sale of other
securities of the Company, together comprising one integrated transaction in
which no specific consideration is allocated to such Options by the parties
thereto, the Options shall be deemed to have been issued for no consideration;
provided, that if such other securities are debt securities (such debt
securities so issued are herein referred to as the "Debt") of the Company or any
of its subsidiaries, the Option shall be deemed to have been issued for
consideration equal to the excess, if any, of (a) the aggregate face amount (the
"Estimated Face Amount") of debt securities with terms identical to the terms of
the Debt (other than the increase to face value described in this proviso) which
the Company or such subsidiary would have had to issue had no Options been
issued in connection therewith, given the prevailing market conditions at the
time of the issuance of the Debt, in order to receive the same aggregate net
proceeds as is actually received from the issuance of the Debt, over (b) the
aggregate face amount of the Debt. The Estimated Face Amount shall be as
mutually agreed between the Company and the Registered Holder or, if no such
mutual agreement is reached, as set forth in the written opinion, addressed to
the Registered Holder, of an investment bank of national recognition, retained
by the Company and reasonably acceptable to the Registered Holder; provided,
that if no such mutual agreement is reached or written opinion is received, the
Estimated Face Amount shall be deemed to be zero (0); and provided, further,
that the fees and expenses of such investment bank shall be borne by the
Company.

     Example:  If the Company issues $20 million aggregate principal amount of
     -------
               10% subordinated debentures with a 10-year maturity (and receives
               aggregate net proceeds of $20 million), and in connection
               therewith issues warrants, and in accordance with the provisions
               of Section 2B (vi), the Company and the Registered Holder
               mutually agree or an investment bank determines that the
               Estimated Face Amount of the subordinated debentures (with terms
               otherwise identical to the securities issued) would have been $21
               million to the Company, had the warrants not been issued, then
               such warrants would be deemed to have been issued for $1 million.

               (vii)  Treasury Shares.  The number of shares of Common Stock
                      ---------------
outstanding at any given time does not include shares owned or held by or for
the account of the Company or any subsidiary of the Company and the disposition
of any shares so owned or held shall be considered an issue or sale of Common
Stock.

               (viii) Record Date. If the Company takes a record of the holders
                      -----------
of Common Stock for the purpose of entitling them (A) to receive a dividend or
other distribution payable in Common Stock, Options or Convertible Securities or
(B) to subscribe for or purchase Common Stock, Options or Convertible
Securities, then such record date shall be deemed to be the date of the issue or
sale of the shares of Common Stock deemed to have been issued or sold

                                       8
<PAGE>

upon the declaration of such dividend or the making of such other distribution
or the date of the granting of such right of subscription or purchase, as the
case may be.

          C.   Subdivision or Combination of Common Stock.  Other than the
               ------------------------------------------
Permitted Issuances, if the Company at any time subdivides (by any stock split,
stock dividend, recapitalization or otherwise) the Common Stock into a greater
number of shares or pays a dividend or makes a distribution to holders of the
Common Stock in the form of shares of Common Stock, the Common Exercise Price in
effect immediately prior to such subdivision shall be proportionately reduced
and the number of Common Warrant Shares obtainable upon exercise of this Warrant
shall be proportionately increased. If the Company at any time combines (by
reverse stock split or otherwise) the Common Stock into a smaller number of
shares, the Common Exercise Price in effect immediately prior to such
combination shall be proportionately increased and the number of Common Warrant
Shares obtainable upon exercise of this Warrant shall be proportionately
decreased.

          D.   Subdivision or Combination of Series A Preferred Stock.  If the
               ------------------------------------------------------
Company at any time subdivides (by any stock split, stock dividend,
recapitalization or otherwise) the Series A Preferred Stock into a greater
number of shares or pays a dividend or makes a distribution to holders of the
Series A Preferred Stock in the form of shares of Series A Preferred Stock, the
Preferred Exercise Price in effect immediately prior to such subdivision shall
be proportionately reduced and the number of Preferred Warrant Shares obtainable
upon exercise of this Warrant shall be proportionately increased. If the Company
at any time combines (by reverse stock split or otherwise) the Series A
Preferred Stock into a smaller number of shares, the Preferred Exercise Price in
effect immediately prior to such combination shall be proportionately increased
and the number of Preferred Warrant Shares obtainable upon exercise of this
Warrant shall be proportionately decreased.

          E.   Organic Change.  Other than the Permitted Issuances, any
               --------------
recapitalization, reorganization, reclassification, consolidation, merger, sale
of all or substantially all of the Company's assets or other transaction which
is effected in such a way that holders of Common Stock or Series A Preferred
Stock are entitled to receive (either directly or upon subsequent liquidation)
stock, securities or assets with respect to or in exchange for Common Stock or
Series A Preferred Stock is referred to herein as an "Organic Change". Subject
to the provisions of the Securities Agreement, prior to the consummation of any
Organic Change, the Company shall make appropriate provision to ensure that each
holder of Warrants shall thereafter have the right to acquire and receive upon
exercise thereof, in lieu of or addition to (as the case may be) the Warrant
Shares immediately theretofore acquirable and receivable upon exercise of such
holder's Warrants, such shares of stock, securities or assets as may be issued
or payable with respect to or in exchange for the number of Warrant Shares
immediately theretofore acquirable and receivable upon exercise of such holder's
Warrants had such Organic Change not taken place. In any such case, the Company
shall make appropriate provision with respect to such holder's rights and
interests to insure that the provisions hereof (including this Section 2) shall
thereafter be applicable to the Warrants (including, in the case of any such
Organic Change in which the successor entity or purchasing entity is other than
the Company, an immediate

                                       9
<PAGE>

adjustment of the Exercise Prices to the value for the Common Stock or Series A
Preferred Stock reflected by the terms of such Organic Change and a
corresponding immediate adjustment in the number of Warrant Shares acquirable
and receivable upon exercise of the Warrants, if the value so reflected is less
than the Fair Market Value of the Common Stock, or the Series A Issue Price of
the Series A Preferred Stock, as applicable, in effect immediately prior to such
Organic Change). The Company shall not effect any such Organic Change unless,
prior to the consummation thereof, the successor entity (if other than the
Company) resulting from such Organic Change (including a purchaser of all or
substantially all the Company's assets) assumes by written instrument the
obligation to deliver to each holder of Warrants such shares of stock,
securities or assets as, in accordance with the foregoing provisions, such
holder may be entitled to acquire upon exercise of Warrants.

          F.   Certain Events.  If any event occurs of the type contemplated by
               --------------
the provisions of this Section 2 but not expressly provided for by such
provisions (including, without limitation, the granting of stock appreciation
rights, phantom stock rights or other rights with equity features); then the
Company's Board of Directors shall make in good faith an appropriate adjustment
in the Exercise Prices and the number of Warrant Shares obtainable upon exercise
of this Warrant so as to protect the rights of the holder of this Warrant.

          G.   Notices.
               -------

               (i)   Immediately upon any adjustment of the Exercise Prices, the
Company shall give written notice thereof to the Registered Holder, setting
forth in reasonable detail and certifying the calculation of such adjustment.

               (ii)  The Company shall give written notice to the Registered
Holder at least 30 days prior to the date on which the Company closes its books
or takes a record (A) with respect to any dividend or distribution upon the
Common Stock or Series A Preferred Stock, (B) with respect to any pro rata
subscription offer to holders of Common Stock or Series A Preferred Stock, or
(C) for determining rights to vote with respect to any Organic Change,
dissolution or liquidation.

               (iii) The Company shall also give written notice to the
Registered Holder at least 30 days prior to the date on which any Organic
Change, dissolution or liquidation shall take place.

     SECTION 3. Certain Rights of Holders Regarding Dividends.
                ---------------------------------------------

          A.   Common Stock.  If the Company pays a dividend or distribution
               ------------
upon the Common Stock, other than dividends or distributions described in
Section 2C, then the Company shall pay to the holder of this Warrant, at the
time of payment thereof, the amount of cash which would have been paid to such
holder had this Warrant been fully exercised immediately prior to the date on
which a record is taken for such dividend or distribution or, if no record is
taken, the date as of which the record holders of Common Stock entitled to said
dividends or distributions are to be determined.

                                       10
<PAGE>

          B.   Preferred Stock.
               ---------------

               (i)  If the Company pays a dividend or distribution upon the
Series A Preferred Stock in cash including any payment made upon a redemption of
Series A Preferred Stock, then the Company shall pay to the holder of this
Warrant, at the time of payment thereof, the amount of cash which would have
been paid to such holder had this Warrant been fully exercised as of the date
hereof. Upon the Company's redemption of Series A Preferred Stock, the Warrant
shall be deemed exercised and shall terminate with respect to the Series A
Preferred Stock subject to such redemption.

               (ii) Notwithstanding the foregoing, immediately prior to the
conversion of Series A Preferred Stock (as provided in the Certificate of
Incorporation of the Company) and at every Dividend Accrual Date (as defined in
the Certificate of Incorporation of the Company) for which dividends accrue on
the Series A Preferred Stock but are not paid, the Preferred Warrant Shares for
which this Warrant is exercisable shall be increased by the number of shares of
Series A Preferred Stock determined by a fraction, (x) the numerator of which is
the dollar amount of the dividend that would have accrued on the Preferred
Warrant Shares had this Warrant been fully exercised as of the date hereof and
(y) the denominator of which is the Series A Issue Price. If the Preferred
Warrant Shares for which this Warrant is exercisable are increased pursuant to
this Section 3(B)(ii) for any Dividend Accrual Date, then no cash payments shall
be made pursuant to Section 3(B)(i) hereof due to cash dividends which were paid
in arrears with respect to any such Dividend Accrual Date.

     SECTION 4. Purchase Rights.  Other than in connection with a Permitted
                ---------------
Issuance, if at any time the Company grants, issues or sells any Options,
Convertible Securities or other such property pro rata to the record holders of
the Common Stock or Series A Preferred Stock (the "Purchase Rights"), then the
Company shall distribute to the Registered Holder the aggregate Purchase Rights
which such holder would have acquired if such holder had held the maximum number
of Warrant Shares acquirable upon complete exercise of this Warrant immediately
before the date on which a record is taken for the grant, issuance or sale of
such Purchase Rights or, if no such record is taken, the date as of which the
record holders of Common Stock or Series A Preferred Stock are to be determined
for the grant, issue or sale of such Purchase Rights.

notice by the holder of this Warrant to the Company (or such earlier date if
