                  This Warrant is one of one or more warrants (the "Warrants")
of the same form and having similar terms except with respect to certain put
rights and the right to obtain additional Warrant Shares, entitling the holders
initially to purchase up to an aggregate of 28,723 shares of Common Stock (the
"Original Exercise Amount"), as the number of shares of Common Stock subject to
the Warrants that are to be issued upon the exercise of the Warrants may be
increased as provided in Section 5.5 of this Warrant (the "Additional Exercise
Amount"). The Warrants have been issued pursuant to the Note, Warrant and
Preferred Stock Purchase Agreement dated as of July 23, 1996 (as amended from
time to time, the "Purchase Agreement") among the Company and the Purchasers
listed on the signature pages thereof, and the Holder is entitled to certain
benefits and is subject to certain obligations as set forth therein and to
certain benefits and certain obligations described in the Stockholder Agreement
and the Registration Rights Agreement (as those terms are hereinafter defined).
The Company shall keep copies of the Purchase Agreement, the Stockholder
Agreement, and the Registration Rights Agreement, and any amendments thereto, at
the Warrant Agency and shall furnish, without charge, copies thereof to the
Holder upon request.

                  This is an Amended and Restated Warrant in respect of the
Warrant that was issued by the Company on July 23, 1996 to Holder (the "Original
Warrant"). The Company and Holder desire to make certain changes to the terms of
the Original Warrant, including an increase in the number of Warrant Shares (as
defined herein) in an amount equal to the Additional Exercise Amount.

          Certain terms used in this Warrant are defined in Article VI.

                                    ARTICLE I

                              EXERCISE OF WARRANTS

                  1.1. Method of Exercise. To exercise this Warrant in whole or
in part, the Holder shall deliver on any Business Day to the Company at the
Warrant Agency, (a) this Warrant, (b) a written notice of such Holder's election
to exercise this Warrant, which notice shall specify the number of shares of
Common Stock to be purchased (which shall be a minimum of 10 whole shares if for
less than all the shares then issuable hereunder), the denominations of the
share certificate or certificates desired and the name or names in which such
certificates are to be registered, and (c) payment of the Exercise Price with
respect to such shares. Such payment may be made, at the option of the Holder,
either (a) by cash, certified or bank cashier's check or wire transfer in an
amount equal to the product of (i) the Exercise Price times (ii) the number of
Warrant Shares as to which this Warrant is being exercised or (b) at any time on
or after the date of consummation of the initial public offering of the Common
Stock by receiving from the Company the number of Warrant Shares equal to (i)
the number of Warrant Shares as to which this Warrant is being exercised minus
(ii) the number of Warrant Shares having a value, based on (x) on the date of
consummation of the initial public offering of the Common Stock, the public
offering price thereof and (y) thereafter the Closing Price on the trading day
immediately prior to the date of such exercise, equal to the product of (x) the
Exercise Price times (y) the number of Warrant Shares as to which this Warrant
is being exercised.

                  The Company shall, as promptly as practicable and in any event
within seven days after receipt of such notice and payment, execute and deliver
or cause to be executed and delivered, in accordance with such notice, a
certificate or certificates representing the aggregate

<PAGE>   3

number of shares of Common Stock specified in said notice together with cash in
lieu of any fractions of a share as provided in Section 1.3. The share
certificate or certificates so delivered shall be in such denominations as may
be specified in such notice, and shall be issued in the name of the Holder or
such other name or names as shall be designated in such notice. This Warrant
shall be deemed to have been exercised and such certificate or certificates
shall be deemed to have been issued, and such Holder or any other Person so
designated to be named therein shall be deemed for all purposes to have become a
holder of record of shares, as of the date the aforementioned notice and payment
is received by the Company. If this Warrant shall have been exercised only in
part, the Company shall, at the time of delivery of such certificate or
certificates, deliver to the Holder a new Warrant evidencing the rights to
purchase the remaining shares of Common Stock called for by this Warrant, which
new Warrant shall in all other respects be identical with this Warrant, or, at
the request of the Holder, appropriate notation may be made on this Warrant
which shall then be returned to the Holder. The Company shall pay all expenses,
taxes and other charges payable in connection with the preparation, issuance and
delivery of share certificates and new Warrants, except that, if share
certificates or new Warrants shall be registered in a name or names other than
the name of the Holder, funds sufficient to pay all transfer taxes payable as a
result of such transfer shall be paid by the Holder at the time of delivery of
the aforementioned notice of exercise or promptly upon receipt of a written
request of the Company for payment.

                  1.2. Shares to be Fully Paid and Nonassessable. All shares of
Common Stock issued upon the exercise of this Warrant shall be validly issued,
fully paid and nonassessable and, if such class of Common Stock is then listed
on any national securities exchange (as defined in the Exchange Act) or quoted
on NASDAQ, shall be duly listed or quoted thereon, as the case may be.

                  1.3. No Fractional Shares Required to be Issued. The Company
shall not be required to issue fractions of shares of Common Stock upon exercise
of this Warrant. If any fraction of a share would, but for this Section, be
issuable upon final exercise of this Warrant, in lieu of such fractional share
the Company may, at its option, pay to the Holder, in cash, an amount equal to
the same fraction of the Fair Market Value of the Company per share of
outstanding Common Stock on the Business Day immediately prior to the date of
such exercise.

                  1.4. Share Legend. Each certificate for shares of Common Stock
issued upon exercise of this Warrant, unless at the time of exercise such shares
are registered under the Securities Act, shall bear the following legend:

                  "This security has not been registered under the Securities
                  Act of 1933 and may not be sold or offered for sale unless
                  registered under said Act and any applicable state securities
                  laws or unless an exemption from such registration is
                  available."

In addition, each such certificate shall bear the legend set forth in Section 6
of the Stockholder Agreement.

                  Any certificate issued at any time in exchange or substitution
for any certificate bearing such legend (except a new certificate issued upon
completion of a public offering pursuant to a registration statement under the
Securities Act) shall also bear such legend unless, in the opinion of counsel
selected by the holder of such certificate (who may be an employee of such
holder) and reasonably acceptable to the Company, the securities represented
thereby need no longer be subject to restrictions on resale under the Securities
Act.

<PAGE>   4

                  1.5. Reservation. The Company has duly reserved and will keep
available for issuance upon exercise of the Warrants the total number of Warrant
Shares deliverable from time to time upon exercise of all Warrants from time to
time outstanding and the total number of shares of Common Stock deliverable upon
conversion of such Warrant Shares to Common Stock.

                     WARRANT AGENCY; TRANSFER, EXCHANGE AND
                             REPLACEMENT OF WARRANTS

                  2.1. Warrant Agency. As long as any of the Warrants remain
outstanding, the Company shall perform the obligations of and be the warrant

specify by notice to all Warrantholders.

                  2.2. Ownership of Warrant. The Company may deem and treat the

other than the Company) for all purposes and shall not be affected by any notice
to the contrary, until due presentment of this Warrant for registration of
transfer as provided in this Article II.

                  2.3. Registration of Warrants. The Company agrees to maintain
at the Warrant Agency books for the registration of transfers of the Warrants,
and any transfer of this Warrant and all rights hereunder pursuant to and in
accordance with Section 2.7 below shall be registered, in whole or in part, on
such books, upon surrender of this Warrant at the Warrant Agency, together with
a written assignment of this Warrant duly executed by the Holder or its duly
authorized agent or attorney, with (if the Holder is a natural person)
signatures guaranteed by a bank or trust company or a broker or dealer
registered with the NASD, and funds sufficient to pay any transfer taxes payable
upon such transfer. Upon surrender and, if required, such payment, the Company
shall execute and deliver a new Warrant or Warrants in the name of the assignee
or assignees and in the denominations specified in the instrument of assignment
(which shall be whole numbers of shares only) and shall issue to the assignor a
new Warrant evidencing the portion of this Warrant not so assigned, and this
Warrant shall promptly be canceled.

                  2.4. Division or Combination of Warrants. This Warrant may be
divided or combined with other Warrants held by the Holder upon presentment
hereof and of any Warrant or Warrants with which this Warrant is to be combined
at the Warrant Agency, together with a written notice specifying the names and
denominations (which shall be whole numbers of shares only) in which the new
Warrant or Warrants are to be issued, signed by the Holder hereof or its
respective duly authorized agents or attorneys. Subject to compliance with
Sections 2.3 and 2.7 as to any transfer or assignment which may be involved in
the division or combination, the Company shall execute and deliver a new Warrant
or Warrants in exchange for the Warrant or Warrants to be divided or combined in
accordance with such notice.

                  2.5. Loss, Theft, Destruction of Warrant Certificates. Upon
receipt of evidence satisfactory to the Company of the ownership of and the
loss, theft, destruction or mutilation of any Warrant and, in the case of any
such loss, theft or destruction, upon receipt of indemnity or security
satisfactory to the Company (it being understood and agreed that if the holder
of such Warrant is the Purchaser, then a written agreement of indemnity given by
the Purchaser alone

<PAGE>   5

shall be satisfactory to the Company and no further security shall be required)
or, in the case of any such mutilation, upon surrender and cancellation of such
Warrant, the Company will make and deliver, in lieu of such lost, stolen,
destroyed or mutilated Warrant, a new Warrant of like tenor and representing the
right to purchase the same aggregate number of shares of Common Stock.

                  2.6. Expenses of Delivery of Warrants. The Company shall pay
all expenses, taxes (other than transfer taxes) and other charges payable in
connection with the preparation, issuance and delivery of Warrants hereunder.

                  2.7. Restrictions on Transfer.

                  (a)  General Restriction. The Warrants shall be transferable
only upon satisfaction of the conditions set forth in this Section 2.7 and any
applicable provisions of the Stockholder Agreement.

                  (b)  Transfer Notice; Opinion. Prior to any transfer of any
Warrants, the transferor thereof shall deliver (i) if reasonably determined by
the Company to be necessary with respect to such transfer, an opinion addressed
to the Company of counsel nominated by the transferor and reasonably acceptable
to the Company (which may be in-house counsel for a Purchaser), that such
transfer may be effected without registration of such Warrants under the
Securities Act, and (ii) the written agreement of the proposed transferee to be
bound by all of the provisions of the Stockholder Agreement and the Registration
Rights Agreement.

                                   ARTICLE III

                                 CERTAIN RIGHTS

                  3.1. Rights and Obligations under the Stockholder Agreement
and the Registration Rights Agreement. This Warrant is entitled to the benefits

regular meetings of the Board of Directors of the Company during each calendar
year at such times and places as shall be determined from time to time by the
Board of Directors. The Company shall give to the Holder notice of all meetings

meetings of such board or committees is required to be given to directors who do
not waive such notice (or, if such action requires no notice, then 10 days
written notice thereof describing the matters upon which action is to be taken).
The Holder shall have the right to send a representative selected by such Holder

                                   ARTICLE IV

                             ANTIDILUTION PROVISIONS

                  4.1. Adjustment Generally. The Exercise Price and the number
of shares of Common Stock (or other securities or property) issuable upon
exercise of this Warrant shall be subject to adjustment from time to time upon
the occurrence of certain events as provided in this Article IV; provided, that
the Exercise Price and the number of shares of Common Stock issuable

<PAGE>   7

upon exercise of this Warrant shall not be adjusted pursuant to this Article IV
with respect to the exercise of the Management Options.

                  4.2.  Common Stock Reorganization. If the Company shall
subdivide its outstanding shares of Common Stock (or any class thereof) into a
greater number of shares or consolidate its outstanding shares of Common Stock
(or any class thereof) into a smaller number of shares (any such event being
called a "Common Stock Reorganization"), then (a) the Exercise Price shall be
adjusted, effective immediately after the effective date of such Common Stock
Reorganization, to a price determined by multiplying the Exercise Price in
effect immediately prior to such effective date by a fraction, the numerator of
which shall be the number of shares of Common Stock outstanding on such
effective date before giving effect to such Common Stock Reorganization and the
denominator of which shall be the number of shares of Common Stock outstanding
after giving effect to such Common Stock Reorganization, and (b) the number of
shares of Common Stock subject to purchase upon exercise of this Warrant shall
be adjusted, effective at such time, to a number determined by multiplying the
number of shares of Common Stock subject to purchase immediately before such
Common Stock Reorganization by a fraction, the numerator of which shall be the
number of shares of Common Stock outstanding after giving effect to such Common
Stock Reorganization and the denominator of which shall be the number of shares
of Common Stock outstanding immediately before such Common Stock Reorganization.

                  4.3.  Common Stock Distribution. (a) If the Company shall
issue, sell or otherwise distribute any shares of Common Stock, other than
pursuant to a Common Stock Reorganization (which is governed by Section 4.2
hereof) (any such event, including any event described in paragraphs (b) and (c)
below, being herein called a "Common Stock Distribution"), for a consideration
per share less than the Exercise Price then in effect or less than the Fair
Market Value of the Company per share of outstanding Common Stock on a Fully
Diluted Basis on the date of such Common Stock Distribution (before giving
effect to such Common Stock Distribution), then, effective upon such Common
Stock Distribution, the Exercise Price shall be reduced, if such consideration
per share shall be less then the Exercise Price then in effect but not less than
such Fair Market Value per share, to the lower of the prices (calculated to the
nearest one-thousandth of one cent) determined as provided in clauses (i) and
(ii) below or, if such consideration per share shall be less than such Fair
Market Value per share, to the lowest of the prices (calculated to the nearest
one-thousandth of one cent) determined as provided in clauses (i), (ii) and
(iii) below:

                  (i)   if the Company shall receive any consideration for the
                  Common Stock issued, sold or distributed in such Common Stock
                  Distribution, the consideration per share of Common Stock
                  received by the Company upon such issue, sale or distribution;

                  (ii)  by dividing (A) an amount equal to the sum of (1) the
                  number of shares of Common Stock outstanding immediately prior
                  to such Common Stock Distribution multiplied by the then
                  existing Exercise Price, plus (2) the consideration, if any,
                  received by the Company upon such Common Stock Distribution by
                  (B) the total number of shares of Common Stock outstanding
                  immediately after such Common Stock Distribution; and

                  (iii) by multiplying the Exercise Price in effect immediately
                  prior to such Common Stock Distribution by a fraction, the
                  numerator of which shall be the sum of (A) the number of
                  shares of Common Stock outstanding immediately prior to such
                  Common Stock Distribution multiplied by such Fair Market Value
                  per share on the date of such Common Stock Distribution,

<PAGE>   8

                  plus (B) the consideration, if any, received by the Company
                  upon such Common Stock Distribution, and the denominator of
                  which shall be the product of (1) the total number of shares
                  of Common Stock outstanding immediately after such Common
                  Stock Distribution multiplied by (2) such Fair Market Value
                  per share on the date of such Common Stock Distribution.

                  If any Common Stock Distribution shall require an adjustment
to the Exercise Price pursuant to the foregoing provisions of this paragraph
(a), including by operation of paragraph (b) or (c) below, then, effective at
the time such adjustment is made, the number of shares of Common Stock subject
to purchase upon exercise of this Warrant shall be increased to a number
determined by multiplying the number of shares of Common Stock subject to
purchase immediately before such Common Stock Distribution by a fraction, the
numerator of which shall be the number of shares of Common Stock outstanding
immediately after giving effect to such Common Stock Distribution and the
denominator of which shall be the sum of the number of shares of Common Stock
outstanding immediately before giving effect to such Common Stock Distribution
(both calculated on a Fully Diluted Basis) plus the number of shares of Common
Stock which the aggregate consideration received by the Company with respect to
such Common Stock Distribution would purchase at the Fair Market Value of the
Company per share of outstanding Common Stock on a Fully Diluted Basis on the
date of such Common Stock Distribution (before giving effect to such Common
Stock Distribution). In computing adjustments under this paragraph, fractional
interests in Common Stock shall be taken into account to the nearest
one-thousandth of a share.

                  The provisions of this paragraph (a), including by operation
of paragraph (b) or (c) below, shall not operate to increase the Exercise Price
or reduce the number of shares of Common Stock subject to purchase upon exercise
of this Warrant.

                  (b) If the Company shall issue, sell, distribute or otherwise
grant in any manner (including by assumption) any rights to subscribe for or to
purchase, or any warrants or options for the purchase of Common Stock or any
stock or securities convertible into or exchangeable for Common Stock (such
rights, warrants or options being herein called "Options" and such convertible
or exchangeable stock or securities being herein called "Convertible
Securities"), whether or not such Options or the rights to convert or exchange
any such Convertible Securities in respect of such Options are immediately
exercisable, 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 in respect of such Options (determined by dividing (i) the aggregate
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 Options to acquire Convertible Securities, the minimum
aggregate amount of additional consideration, if any, payable upon the issuance
or sale of such Convertible Securities and upon the conversion or exchange
thereof, by (ii) the total maximum number of shares of Common Stock issuable
upon the exercise of such Options or upon the conversion or exchange of all such
Convertible Securities issuable upon the exercise of such Options) shall be less
than the Exercise Price then in effect or less than the Fair Market Value of the
Company per share of outstanding Common Stock on a Fully Diluted Basis on the
date of granting such Options (before giving effect to such grant), then, for
purposes of paragraph (a) above, 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 have been issued as of the date of
granting of such Options and thereafter shall be deemed to be outstanding and
the Company shall be deemed to have received as consideration of such price per
share, determined as provided above, therefor. Except as otherwise provided in

<PAGE>   9

paragraph (d) below, no additional adjustment of the Exercise Price shall be
made upon the actual exercise of such Options or upon conversion or exchange of
such Convertible Securities.

                  (c) If the Company shall issue, sell or otherwise distribute
(including by assumption) any Convertible Securities, whether or not the rights
to exchange or convert thereunder are immediately exercisable, and the price per
share for which Common Stock is issuable upon such conversion or exchange
(determined by dividing (i) the aggregate amount received or receivable by the
Company as consideration for the issuance, sale or distribution 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 (ii) the total maximum number of shares of Common Stock issuable
upon the conversion or exchange of all such Convertible Securities) shall be
less than the Exercise Price then in effect or less than the Fair Market Value
of the Company per share of outstanding Common Stock on a Fully Diluted Basis on
the date of such issuance, sale or distribution (before giving effect to such
issuance, sale or distribution), then, for purposes of paragraph (a) above, the
total maximum number of shares of Common Stock issuable upon conversion or
exchange of all such Convertible Securities shall be deemed to have been issued
as of the date of the issuance, sale or distribution of such Convertible
Securities and thereafter shall be deemed to be outstanding and the Company
shall be deemed to have received as consideration such price per share,
determined as provided above, therefor. Except as otherwise provided in
paragraph (d) below, no additional adjustment of the Exercise Price shall be
made upon the actual conversion or exchange of such Convertible Securities.

                  (d) If (i) the purchase price provided for in any Option
referred to in paragraph (b) above or the additional consideration, if any,
payable upon the conversion or exchange of any Convertible Securities referred
to in paragraph (b) or (c) above or the rate at which any Convertible Securities
referred to in paragraph (b) or (c) above are convertible into or exchangeable
for Common Stock shall change at any time (other than under or by reason of
provisions designed to protect against dilution upon an event which results in a
related adjustment pursuant to this Article IV), or (ii) any of such Options or
Convertible Securities shall have terminated, lapsed or expired, the Exercise
Price then in effect shall forthwith be readjusted to the Exercise Price which
would then be in effect, and the number of shares of Common Stock then subject
to purchase upon exercise of the Warrant shall be readjusted to the number of
shares of Common Stock which would then be subject to purchase upon exercise of
this Warrant (in each case effective only with respect to any exercise of this
Warrant after such readjustment), had the adjustment made upon the issuance,
sale, distribution or grant of such Options or Convertible Securities been made
based upon such changed purchase price, additional consideration or conversion
rate, as the case may be (in the case of any event referred to in clause (i) of
this paragraph (d)) or had such adjustment not been made (in the case of any
event referred to in clause (ii) of this paragraph (d)).

                  (e) If the Company shall pay a dividend or make any other
distribution upon any capital stock of the Company payable in Common Stock,
Options or Convertible Securities, then, for purposes of paragraph (a) above,
such Common Stock, Options or Convertible Securities shall be deemed to have
been issued or sold without consideration.

                  (f) If any shares of Common Stock, Options or Convertible
Securities shall be issued, sold or distributed for cash, the consideration
received therefor shall be deemed to be the gross amount received by the Company
therefor. If any shares of Common Stock, Options or Convertible Securities shall
be issued sold or distributed for a consideration other than cash, the amount of
the consideration other than cash received by the Company shall be deemed to be
the Fair Market Value of such consideration, after deduction of any expenses
incurred in connection

<PAGE>   10
therewith. If any shares of Common Stock, Options or Convertible Securities
shall be issued in connection with any merger in which the Company is the
surviving corporation, the amount of consideration therefor shall be deemed to
be the Fair Market Value of such portion of the assets and business of the
non-surviving corporation as shall be attributable to such Common Stock, Options
or Convertible Securities, as the case may be. If any Options shall be issued in
connection with the issuance and sale of other securities of the Company,
together comprising one integral transaction in which no specific consideration
is allocated to such Options by the parties thereto, such Options shall be
deemed to have been issued without consideration.

                  4.4. Special Dividends. If the Company shall issue or
distribute to any holder or holders of shares of Common Stock evidences of
indebtedness, any other securities of the Company or any cash, property or other
assets (excluding a Common Stock Reorganization or a Common Stock Distribution),
whether or not accompanied by a purchase, redemption or other acquisition of
shares of Common Stock (any such nonexcluded event being herein called a
"Special Dividend"), (a) the Exercise Price shall be decreased, effective
immediately after the effective date of such Special Dividend, to a price
determined by multiplying the Exercise Price then in effect by a fraction, the
numerator of which shall be the Fair Market Value of the Company per share of
outstanding Common Stock as of such effective date less any cash and the then
Fair Market Value of any evidences of indebtedness, securities or property or
other assets issued or distributed in such Special Dividend with respect to one
share of Common Stock, and the denominator of which shall be such Fair Market
Value per share and (b) the number of shares of Common Stock subject to purchase
upon exercise of this Warrant shall be increased to a number determined by
multiplying the number of shares of Common Stock subject to purchase immediately
before such Special Dividend by a fraction, the numerator of which shall be the
Exercise Price in effect immediately before such Special Dividend and the
denominator of which shall be the Exercise Price in effect immediately after
such Special Dividend. A reclassification of Common Stock (other than a change
in par value, or from par value to no par value or from no par value to par
value) into shares of Common Stock and shares of any other class of stock shall
be deemed a distribution by the Company to the holders of such Common Stock of
such shares of such other class of stock and, if the outstanding shares of
Common Stock shall be changed into a larger or smaller number of shares of
Common Stock as part of such reclassification, a Common Stock Reorganization.

                  4.5. Capital Reorganizations. If there shall be any
consolidation or merger to which the Company is a party, other than a
consolidation or a merger of which the Company is the continuing corporation and
which does not result in any reclassification of, or change (other than a Common
Stock Reorganization) in, outstanding shares of Common Stock, or any sale or
conveyance of the property of the Company as an entirety or substantially as an
entirety, or any recapitalization of the Company (any such event being called a
"Capital Reorganization"), then, effective upon the effective date of such
Capital Reorganization, the Holder shall no longer have the right to purchase
Common Stock, but shall have instead the right to purchase, upon exercise of
this Warrant, the kind and amount of shares of stock and other securities and
property (including cash) which the Holder would have owned or have been
entitled to receive pursuant to such Capital Reorganization if this Warrant had
been exercised immediately prior to the effective date of such Capital
Reorganization. As a condition to effecting any Capital Reorganization, the
Company or the successor or surviving corporation, as the case may be, shall
execute and deliver to each Warrantholder and to the Warrant Agency an agreement
as to the Warrantholders' rights in accordance with this Section 4.5, providing,
to the extent of any right to purchase equity securities hereunder, for
subsequent adjustments as nearly equivalent as may be practicable to the
adjustments provided for in this Article IV. The provisions of this Section 4.5
shall similarly apply to successive Capital Reorganizations.

<PAGE>   11

                  4.6. Adjustment Rules. Any adjustments pursuant to this
Article IV shall be made successively whenever an event referred to herein shall
occur, except that, notwithstanding any other provision of this Article IV, no
adjustment shall be made to the number of shares of Common Stock to be delivered
to each Holder (or to the Exercise Price) if such adjustment represents less
than one percent (1%) of the number of shares previously required to be so
delivered, but any lesser adjustment shall be carried forward and shall be made
at the time and together with the next subsequent adjustment which together with
any adjustments so carried forward shall amount to one percent (1%) or more of
the number of shares to be so delivered. No adjustment shall be made pursuant to
this Article IV in respect of the issuance from time to time of shares of Common
Stock upon the exercise of any of the Warrants. If the Company shall take a
record of the holders of its Common Stock for any purpose referred to in this
Article IV, then (i) such record date shall be deemed to be the date of the
issuance, sale, distribution or grant in question and (ii) if the Company shall
legally abandon such action prior to effecting such action, no adjustment shall
be made pursuant to this Article IV in respect of such action.

                  4.7. Proceedings Prior to Any Action Requiring Adjustment. As
a condition precedent to the taking of any action which would require an
adjustment pursuant to this Article IV, the Company shall take any action which
may be necessary, including obtaining regulatory approvals or exemptions, in
order that the Company may thereafter validly and legally issue as fully paid
and nonassessable all shares of Common Stock which the holders of Warrants are
entitled to receive upon exercise thereof.

                  4.8. Notice of Adjustment. Not less than 10 nor more than 30
days prior to the record date or effective date, as the case may be, of any
action which requires or might require an adjustment or readjustment pursuant to
this Article IV, the Company shall give notice to each Warrantholder of such
event, describing such event in reasonable detail and specifying the record date
or effective date, as the case may be, and, if determinable, the required
adjustment and the computation thereof. If the required adjustment is not
determinable at the time of such notice, the Company shall give notice to each
Warrantholder of such adjustment and computation promptly after such adjustment
becomes determinable.

                                    ARTICLE V

such manner and for such consideration as set forth below.

                  5.2. Put Rights. The Holder shall:

                  (a)    at any time and from time to time on or after the date
                  on which a Triggering Event shall occur, have the right (the
                  "Put Right") to sell back to the Company its Warrant Shares at
                  the greater of (i) the Fair Market Value of all such Warrant
                  Shares or (ii) the cash amount determined by application of
                  the following formula:

                  [(EBITDA times 5) - Term Debt - Minimum Revolving Debt -
                  Preferred Stock + Cash] times Applicable Percentage

<PAGE>   12

                  (b)  Within thirty (30) days of the Company's receipt of
                  notification from the Holder that it wishes to exercise its
                  Put Right (the "Put Notification"), the Company shall
                  repurchase such number of Warrant Shares then held by the
                  Holder as shall be specified in the Put Notification (the
                  "Repurchase Date"). The repurchase price for each Share (the
                  "Repurchase Price") shall be paid in cash on the Repurchase
                  Date or, at the option of the Holder, in the form of an
                  unsecured promissory note in form reasonably satisfactory to
                  the Holder maturing in one year and bearing interest at the
                  rate of twelve percent (12%) per annum.

                  (c)  Surrender the certificate(s) representing Warrant Shares
                  being repurchased to the Company and thereupon the Repurchase
                  Price for such Warrant Shares shall be paid to the order of
                  the person whose name appears on such certificate(s) and each
                  surrendered certificate shall be canceled and retired.

                  5.3. Termination of Put Rights; Limitation. Notwithstanding
anything herein to the contrary, (a) the Put Rights shall terminate upon the
closing of a Qualified IPO, and (b) the Holder shall have the right to exercise
no more than three (3) Put Rights.

                  5.4. Cancellation of Warrants. All Warrants purchased,
redeemed or otherwise acquired by the Company shall thereupon be canceled and
retired. The Warrant Agency shall cancel any Warrant surrendered for exercise or
registration of transfer or exchange and deliver such canceled Warrants to the
Company.

                  5.5 Increase of Warrant Shares. If the Company has not
redeemed or repurchased all of the Holder Warrant Shares on or prior to July 18,
2002, then on July 23, 2002 and on each October 23, January 23, April 23, and
July 23 thereafter (each a "Warrant Share Increase Date"), on which any of the
Holder Warrant Shares have not been redeemed or repurchased by the Company, then
the number of shares of Common Stock that are subject to this Warrant shall
automatically, and without any act of the Company or its Board of Directors,
increase by an amount equal to the product of:

         (a) the number of shares of outstanding Common Stock of the Company on
         a Fully Diluted Basis as of July 23, 2002; and

         (b) .32% (provided that, in the event that this Warrant is transferred
         or assigned, the percentage set forth in this subsection (b) shall be
         adjusted on a pro rata basis among the Warrants issued as a result of
         such transfer or assignment so that the aggregate sum of such
         percentages set forth in all of the Warrants resulting from the
         transfer or assignment of this Warrant shall equal .32%) multiplied by
         a fraction, the numerator of which shall be the number of Holder
         Warrant Shares that have not been redeemed (excluding those shares
         attributable to the Additional Exercise Amount) and the denominator of
         which shall be the initial number of Holder Warrant Shares (i.e.,
         18,382.72, assuming no adjustments pursuant to Article IV hereof).

confirmed telex or facsimile transmission and shall, unless otherwise expressly
required, be deemed given when received or, if mailed, four Business Days after

                  7.2. Waivers; Amendments. No failure or delay of the Holder in
exercising any power or right hereunder shall operate as a waiver thereof, nor
shall any single or partial exercise of any such right or power, or any
abandonment or discontinuance of steps to enforce such a right or power,
preclude any other or further exercise thereof or the exercise of any other
right or power. The rights and remedies of the Holder are cumulative and not
exclusive of any rights or remedies which it would otherwise have. The
provisions of this Warrant may be amended, modified or waived with (and only
with) the written consent of the Company and the holders of Warrants entitling
such holders to purchase a majority of the Common Stock subject to purchase upon
exercise of such Warrants at the time outstanding (exclusive of Warrants then
owned by the Company or any Subsidiary (as defined in the Purchase Agreement) or
Affiliate (as defined in the Purchase Agreement) thereof); provided, however,
that no such amendment, modification or waiver shall, without the written
consent of the holders of all Warrants at the time outstanding, (a) change the
number of shares of Common Stock subject to purchase upon exercise of this
Warrant, the Exercise Price or provisions for payment thereof or (b) amend,
modify or waive the provisions of this Section 7.2 or Article III, IV or V or
Section 1.5. The provisions of the Purchase Agreement may be amended, modified
or waived only in accordance with the respective provisions thereof.

                  Any such amendment, modification or waiver effected pursuant
to and in accordance with the provisions of this Section or the applicable
provisions of the Purchase Agreement shall be binding upon the holders of all
Warrants and Warrant Shares, upon each future holder thereof and upon the
Company. In the event of any such amendment, modification or waiver the Company
shall give prompt notice thereof to all holders of Warrants and Warrant Shares
and, if appropriate, notation thereof shall be made on all Warrants thereafter
surrendered for registration of transfer or exchange.

                  No notice or demand on the Company in any case shall entitle
the Company to any other or future notice or demand in similar or other
circumstances.

                  7.3. GOVERNING LAW. THIS WARRANT SHALL BE CONSTRUED IN
ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF MICHIGAN (WITHOUT
REGARD TO PRINCIPLES OF CONFLICTS OF LAW).

                  7.4. Transfer; Covenants to Bind Successor and Assigns. All
covenants, stipulations, promises and agreements in this Warrant contained by or
on behalf of the Company or the Holder shall bind its successors and assigns,
whether so expressed or not. This Warrant shall be transferable and assignable
by the Holder hereof in whole or from time to time in part to any other Person
and the provisions of this Warrant shall be binding upon and inure to the
benefit of the Holder hereof and its successors and assigns.

<PAGE>   18

                  7.5. Severability. In case any one or more of the provisions
contained in this Warrant shall be invalid, illegal or unenforceable in any
respect, the validity, legality and enforceability of the remaining provisions
contained herein shall not in any way be affected or impaired thereby. The
parties shall endeavor in good faith negotiations to replace the invalid,
illegal or unenforceable provisions with valid provisions the economic effect of
which comes as close as possible to that of the invalid, illegal or
unenforceable provisions.

                  7.6. Section Headings. The section headings used herein are
for convenience of reference only, are not part of this Warrant and are not to
affect the construction of or be taken into consideration in interpreting this
Warrant.

                  7.7. Tax Basis. The Company and the Holder agree pursuant to
Proposed Treasury Regulation Section 1.1273-2 that, for Federal income tax
purposes, the aggregate issue price of the Notes (as defined in the Purchase
Agreement) and the aggregate purchase price for the Warrants are those set forth
in Section 2.04 of the Purchase Agreement. Neither the Company nor the Holder
hereof shall voluntarily take any action inconsistent with the agreement set
forth in this Section 7.7.

                  IN WITNESS WHEREOF, the Company has caused this Warrant to be
executed in its corporate name by one of its officers thereunto duly authorized,
and its corporate seal to be hereunto affixed, attested by its Secretary or an
Assistant Secretary, all as of the day and year first above written.

<PAGE>   20

         (C) This Amendment may be executed in two or more counterparts, each of

                                                         Dated: October 17, 1997

                 To Purchase 10,340.28 Shares of Common Stock of

                     MICROWAVE COMPONENTS ENTERPRISES, INC.

          Expiring on the earlier of (i) July 23, 2007 or (ii)
     the date which is six years after the date on which the Company's 12%
      Promissory Notes due July 23, 2001 in the aggregate principal amount
                       of $3,500,000 shall be paid in full

                  THIS IS TO CERTIFY THAT, for value received, HANIFEN IMHOFF
MEZZANINE FUND, L.P. or registered assigns ("Holder") is entitled to purchase
from MICROWAVE COMPONENTS ENTERPRISES, INC., a Michigan corporation (the
"Company"), at any time or from time to time after 9:00 a.m., New York City
time, on and after the earlier of (a) the date on which a Triggering Event (as
hereinafter defined) shall occur or (b) July 23, 2001, and prior to 5:00 p.m.,
New York City time, and on the earlier of (i) July 23, 2007, (ii) the date which
is six years after the date on which the Company's 12% Promissory Notes due July
23, 2001 in the aggregate principal amount of $3,500,000 shall be paid in full
or (iii) the Business Day preceding the date of redemption of this Warrant, at
the place where the Warrant Agency is located, at the Exercise Price, the number
of shares of Common Stock, without par value per share (the "Common Stock") of
the Company shown above, all subject to adjustment and upon the terms and
conditions hereinafter provided, and is entitled also to exercise the other
appurtenant rights, powers and privileges hereinafter described.

                  This Warrant is one of one or more warrants (the "Warrants")
of the same form and having similar terms except with respect to certain put
rights and the right to obtain additional

<PAGE>   2

Warrant Shares, entitling the holders initially to purchase up to an aggregate
of 28,723 shares of Common Stock (the "Original Exercise Amount"). The Warrants
have been issued pursuant to the Note, Warrant and Preferred Stock Purchase
Agreement dated as of July 23, 1996 (as amended from time to time, the "Purchase
Agreement") among the Company and the Purchasers listed on the signature pages
thereof, and the Holder is entitled to certain benefits and is subject to
certain obligations as set forth therein and to certain benefits and certain
obligations described in the Stockholder Agreement and the Registration Rights
Agreement (as those terms are hereinafter defined). The Company shall keep
copies of the Purchase Agreement, the Stockholder Agreement, and the
Registration Rights Agreement, and any amendments thereto, at the Warrant Agency
and shall furnish, without charge, copies thereof to the Holder upon request.

             This is an Amended and Restated Warrant in respect of the
Warrant that was issued by the Company on July 23, 1996 to Holder (the "Original
Warrant"). The Company and Holder desire to make certain changes to the terms of
the Original Warrant so as to reflect the fact that certain changes are being
made to one of the Warrants issued to another holder.

             Certain terms used in this Warrant are defined in Article VI.

                                   ARTICLE I

                              EXERCISE OF WARRANTS

             1.1. Method of Exercise. To exercise this Warrant in whole or
in part, the Holder shall deliver on any Business Day to the Company at the
Warrant Agency, (a) this Warrant, (b) a written notice of such Holder's election
to exercise this Warrant, which notice shall specify the number of shares of
Common Stock to be purchased (which shall be a minimum of 10 whole shares if for
less than all the shares then issuable hereunder), the denominations of the
share certificate or certificates desired and the name or names in which such
certificates are to be registered, and (c) payment of the Exercise Price with
respect to such shares. Such payment may be made, at the option of the Holder,
either (a) by cash, certified or bank cashier's check or wire transfer in an
amount equal to the product of (i) the Exercise Price times (ii) the number of
Warrant Shares as to which this Warrant is being exercised or (b) at any time on
or after the date of consummation of the initial public offering of the Common
Stock by receiving from the Company the number of Warrant Shares equal to (i)
the number of Warrant Shares as to which this Warrant is being exercised minus
(ii) the number of Warrant Shares having a value, based on (x) on the date of
consummation of the initial public offering of the Common Stock, the public
offering price thereof and (y) thereafter the Closing Price on the trading day
immediately prior to the date of such exercise, equal to the product of (x) the
Exercise Price times (y) the number of Warrant Shares as to which this Warrant
is being exercised.

             The Company shall, as promptly as practicable and in any event
within seven days after receipt of such notice and payment, execute and deliver
or cause to be executed and delivered, in accordance with such notice, a
certificate or certificates representing the aggregate number of shares of
Common Stock specified in said notice together with cash in lieu of any
fractions of a share as provided in Section 1.3. The share certificate or
certificates so delivered shall be in such denominations as may be specified in
such notice, and shall be issued in the name of the Holder or such other name
or names as shall be designated in such notice. This Warrant shall be
deemed to have been exercised and such certificate or certificates shall be
deemed to have been issued, and such Holder or any other Person so designated
to be named therein shall be

<PAGE>   3
deemed for all purposes  to have  become a  holder  of  record  of  shares,  as
of the date the aforementioned  notice and payment is received by the  Company.
If this Warrant shall  have been  exercised  only in part,  the  Company  shall,
at the time of delivery  of such  certificate  or  certificates,  deliver  to
the  Holder a new Warrant  evidencing the rights to purchase the remaining
shares of Common Stock called for by this  Warrant,  which new Warrant  shall in
all other  respects be identical  with this  Warrant,  or, at the  request of
the  Holder,  appropriate notation may be made on this Warrant which shall then
be returned to the Holder. The  Company  shall  pay all  expenses,  taxes  and
other  charges  payable  in connection with the preparation, issuance and
delivery of share certificates and new  Warrants,  except that,  if share
certificates  or new  Warrants  shall be registered  in a name  or  names  other
than  the  name  of the  Holder,  funds sufficient to pay all transfer  taxes
payable as a result of such transfer shall be paid by the Holder at the time of
delivery of the  aforementioned  notice of exercise  or  promptly  upon  receipt
of a written  request of the  Company  for payment.

                  1.2. Shares to be Fully Paid and Nonassessable. All shares of
Common Stock issued upon the exercise of this Warrant shall be validly issued,
fully paid and nonassessable and, if such class of Common Stock is then listed
on any national securities exchange (as defined in the Exchange Act) or quoted
on NASDAQ, shall be duly listed or quoted thereon, as the case may be.

                  1.3. No Fractional Shares Required to be Issued. The Company
shall not be required to issue fractions of shares of Common Stock upon exercise
of this Warrant. If any fraction of a share would, but for this Section, be
issuable upon final exercise of this Warrant, in lieu of such fractional share
the Company may, at its option, pay to the Holder, in cash, an amount equal to
the same fraction of the Fair Market Value of the Company per share of
outstanding Common Stock on the Business Day immediately prior to the date of
such exercise.

                  1.4. Share Legend. Each certificate for shares of Common Stock
issued upon exercise of this Warrant, unless at the time of exercise such shares
are registered under the Securities Act, shall bear the following legend:

                  "This security has not been registered under the Securities
                  Act of 1933 and may not be sold or offered for sale unless
                  registered under said Act and any applicable state securities
                  laws or unless an exemption from such registration is
                  available."

In addition, each such certificate shall bear the legend set forth in Section 6
of the Stockholder Agreement.

                  Any certificate issued at any time in exchange or substitution
for any certificate bearing such legend (except a new certificate issued upon
completion of a public offering pursuant to a registration statement under the
Securities Act) shall also bear such legend unless, in the opinion of counsel
selected by the holder of such certificate (who may be an employee of such
holder) and reasonably acceptable to the Company, the securities represented
thereby need no longer be subject to restrictions on resale under the Securities
Act.

                  1.5. Reservation. The Company has duly reserved and will keep
available for issuance upon exercise of the Warrants the total number of Warrant
Shares deliverable from time to time upon exercise of all Warrants from time to
time outstanding and the total number of shares of Common Stock deliverable upon
conversion of such Warrant Shares to Common Stock.

                             REPLACEMENT OF WARRANTS

                  2.1. Warrant Agency. As long as any of the Warrants remain
outstanding, the Company shall perform the obligations of and be the warrant
agency with respect to the Warrants (the "Warrant Agency") at its address set
forth in the Credit Agreement or at such other address as the Company shall
specify by notice to all Warrantholders.

                  2.2. Ownership of Warrant. The Company may deem and treat the
person in whose name this Warrant is registered as the holder and owner hereof
(notwithstanding any notations of ownership or writing hereon made by any person
other than the Company) for all purposes and shall not be affected by any notice
to the contrary, until due presentment of this Warrant for registration of
transfer as provided in this Article II.

                  2.3. Registration of Warrants. The Company agrees to maintain
at the Warrant Agency books for the registration of transfers of the Warrants,
and any transfer of this Warrant and all rights hereunder pursuant to and in
accordance with Section 2.7 below shall be registered, in whole or in part, on
such books, upon surrender of this Warrant at the Warrant Agency, together with
a written assignment of this Warrant duly executed by the Holder or its duly
authorized agent or attorney, with (if the Holder is a natural person)
signatures guaranteed by a bank or trust company or a broker or dealer
registered with the NASD, and funds sufficient to pay any transfer taxes payable
upon such transfer. Upon surrender and, if required, such payment, the Company
shall execute and deliver a new Warrant or Warrants in the name of the assignee
or assignees and in the denominations specified in the instrument of assignment
(which shall be whole numbers of shares only) and shall issue to the assignor a
new Warrant evidencing the portion of this Warrant not so assigned, and this
Warrant shall promptly be canceled.

                  2.4. Division or Combination of Warrants. This Warrant may be
divided or combined with other Warrants held by the Holder upon presentment
hereof and of any Warrant or Warrants with which this Warrant is to be combined
at the Warrant Agency, together with a written notice specifying the names and
denominations (which shall be whole numbers of shares only) in which the new
Warrant or Warrants are to be issued, signed by the Holder hereof or its
respective duly authorized agents or attorneys. Subject to compliance with
Sections 2.3 and 2.7 as to any transfer or assignment which may be involved in
the division or combination, the Company shall execute and deliver a new Warrant
or Warrants in exchange for the Warrant or Warrants to be divided or combined in
accordance with such notice.

                  2.5. Loss, Theft, Destruction of Warrant Certificates. Upon
receipt of evidence satisfactory to the Company of the ownership of and the
loss, theft, destruction or mutilation of any Warrant and, in the case of any
such loss, theft or destruction, upon receipt of indemnity or security
satisfactory to the Company (it being understood and agreed that if the holder
of such Warrant is the Purchaser, then a written agreement of indemnity given by
the Purchaser alone shall be satisfactory to the Company and no further security
shall be required) or, in the case of any such mutilation, upon surrender and
cancellation of such Warrant, the Company will make and deliver, in lieu of such
lost, stolen, destroyed or mutilated Warrant, a new Warrant of like tenor and
representing the right to purchase the same aggregate number of shares of Common
Stock.

<PAGE>   5

                  2.6.  Expenses of Delivery of Warrants.  The Company shall pay
all  expenses,  taxes (other than transfer  taxes) and other charges  payable in
connection with the preparation, issuance and delivery of Warrants hereunder.

                  2.7.  Restrictions on Transfer.

                  (a) General  Restriction.  The Warrants shall be  transferable
only upon  satisfaction  of the conditions set forth in this Section 2.7 and any
applicable provisions of the Stockholder Agreement.

                  (b) Transfer Notice; Opinion. Prior to any transfer of any
Warrants, the transferor thereof shall deliver (i) if reasonably determined by
the Company to be necessary with respect to such transfer, an opinion addressed
to the Company of counsel nominated by the transferor and reasonably acceptable
to the Company (which may be in-house counsel for a Purchaser), that such
transfer may be effected without registration of such Warrants under the
Securities Act, and (ii) the written agreement of the proposed transferee to be
bound by all of the provisions of the Stockholder Agreement and the Registration
Rights Agreement.

                                   ARTICLE III

                                 CERTAIN RIGHTS

listed on the signature pages thereof (as amended from time to time, the
"Stockholders Agreement," and the "Registration Rights Agreement,"
respectively).

                  3.2. Board Meetings. The Company will hold at least four
regular meetings of the Board of Directors of the Company during each calendar
year at such times and places as shall be determined from time to time by the
Board of Directors. The Company shall give to the Holder notice of all meetings
and actions by written consent of the Board of Directors of the Company and each
committee thereof, at the same time and in the same manner as notice of any
meetings of such board or committees is required to be given to directors who do
not waive such notice (or, if such action requires no notice, then 10 days
written notice thereof describing the matters upon which action is to be taken).
The Holder shall have the right to send a representative selected by such Holder
to each such meeting, who shall be permitted to attend, at the expense of the
Company, such meetings and any adjournments thereof (other than any portion of
such meeting devoted to discussion of the Holder solely in its capacity as a
holder of the Warrants), subject to Section 8.08 of the Purchase Agreement.

                  3.3 Financial  Statements and Other  Information.  The Company
will, and will cause its Subsidiaries to, deliver to any Holder:

                  (a) as soon as practicable and in any event within 30 days
                  after the end of each fiscal quarter, a consolidated and
                  consolidating balance sheet of the Company as at the end of
                  such fiscal quarter and the related statements of operations
                  and cash

                  fiscal year ended at the end of such fiscal  quarter,  setting
                  forth in each case in  comparative  form the  revenues and the
                  other  figures for the  corresponding  periods of the previous
                  fiscal year,  all in  reasonable  detail and  certified by the
                  chief  financial  officer of the Company as fairly  presenting
                  the  financial  condition  and  results of  operations  of the
                  Company  and  as  having  been  prepared  in  accordance  with
                  generally  accepted  accounting  principles applied on a basis
                  consistent  with  the  audited  financial  statements  of  the
                  Company,  subject to changes  resulting  from audit and normal
                  year-end adjustments;

                  (b) as soon as available and in any event within 90 days after
                  the end of each fiscal year, a balance sheet of the Company as
                  of the end of such fiscal year and the related consolidated
                  statements of operations, stockholders' equity and cash flows
                  for such fiscal year, setting forth in each case in
                  comparative form the revenues and the other figures for the
                  previous fiscal year, certified by Ernst & Young LLP, or other
                  independent public accountants of nationally recognized
                  standing;

                  (c) promptly following the filing thereof with the Department
                  of Consumer and Industry Services of the State of Michigan, a
                  copy of each amendment to, or restatement of, the Articles of
                  Incorporation of the Company, and promptly following the
                  adoption thereof by the Company, a copy of each amendment to,
                  or restatement of, the By-laws of the Company;

                  (d) as promptly as practicable following each meeting of the
                  board of directors of the Company, a copy of the minutes of

                  of each unanimous written consent of directors in lieu of a
                  meeting of the board of directors of the Company, in each
                  case, including all exhibits and attachments, if any, to such
                  minutes or unanimous written consents; and

                  (e) with reasonable promptness, such other information and
                  data with respect to the Company or any of its Subsidiaries as
                  from time to time may be reasonably requested by such
                  Warrantholders holding the Required Interest.

                                   ARTICLE IV

                             ANTIDILUTION PROVISIONS

                  4.1. Adjustment Generally. The Exercise Price and the number
of shares of Common Stock (or other securities or property) issuable upon
exercise of this Warrant shall be subject to adjustment from time to time upon
the occurrence of certain events as provided in this Article IV; provided, that
the Exercise Price and the number of shares of Common Stock issuable upon
exercise of this Warrant shall not be adjusted pursuant to this Article IV with
respect to the exercise of the Management Options.

                  4.2. Common Stock Reorganization. If the Company shall
subdivide its outstanding shares of Common Stock (or any class thereof) into a
greater number of shares or consolidate its outstanding shares of Common Stock
(or any class thereof) into a smaller number of shares (any such event being
called a "Common Stock Reorganization"), then (a) the Exercise

<PAGE>   7

Price shall be adjusted,  effective immediately after the effective date of such
Common Stock  Reorganization,  to a price determined by multiplying the Exercise
Price in effect  immediately  prior to such  effective  date by a fraction,  the
numerator of which shall be the number of shares of Common Stock  outstanding on
such effective date before giving effect to such Common Stock Reorganization and
the  denominator  of  which  shall be the  number  of  shares  of  Common  Stock
outstanding after giving effect to such Common Stock Reorganization, and (b) the
number of shares of Common  Stock  subject to  purchase  upon  exercise  of this
Warrant  shall be adjusted,  effective at such time,  to a number  determined by
multiplying the number of shares of Common Stock subject to purchase immediately
before such Common Stock  Reorganization  by a fraction,  the numerator of which
shall be the number of shares of Common Stock outstanding after giving effect to
such  Common  Stock  Reorganization  and the  denominator  of which shall be the
number of shares of Common  Stock  outstanding  immediately  before  such Common
Stock Reorganization.

                  4.3. Common Stock Distribution. (a) If the Company shall
issue, sell or otherwise distribute any shares of Common Stock, other than
pursuant to a Common Stock Reorganization (which is governed by Section 4.2
hereof) (any such event, including any event described in paragraphs (b) and (c)
below, being herein called a "Common Stock Distribution"), for a consideration
per share less than the Exercise Price then in effect or less than the Fair
Market Value of the Company per share of outstanding Common Stock on a Fully
Diluted Basis on the date of such Common Stock Distribution (before giving
effect to such Common Stock Distribution), then, effective upon such Common
Stock Distribution, the Exercise Price shall be reduced, if such consideration
per share shall be less then the Exercise Price then in effect but not less than
such Fair Market Value per share, to the lower of the prices (calculated to the
nearest one-thousandth of one cent) determined as provided in clauses (i) and
(ii) below or, if such consideration per share shall be less than such Fair
Market Value per share, to the lowest of the prices (calculated to the nearest
one-thousandth of one cent) determined as provided in clauses (i), (ii) and
(iii) below:

                  (i) if the Company shall receive any consideration for the
                  Common Stock issued, sold or distributed in such Common Stock
                  Distribution, the consideration per share of Common Stock
                  received by the Company upon such issue, sale or distribution;

             (ii) by dividing (A) an amount equal to the sum of (1) the number
         of shares of Common Stock outstanding immediately prior to such Common
         Stock Distribution multiplied by the then existing Exercise Price, plus
         (2) the consideration, if any, received by the Company upon such Common
         Stock Distribution by (B) the total number of shares of Common Stock
         outstanding immediately after such Common Stock Distribution; and

            (iii) by multiplying the Exercise Price in effect immediately prior
to such Common Stock Distribution by a fraction, the numerator of which shall be
the sum of (A) the number of shares of Common Stock outstanding immediately
prior to such Common Stock Distribution multiplied by such Fair Market Value per
share on the date of such Common Stock Distribution, plus (B) the consideration,
if any, received by the Company upon such Common Stock Distribution, and the
denominator of which shall be the product of (1) the total number of shares of
Common Stock outstanding immediately after such Common Stock Distribution
multiplied by (2) such Fair Market Value per share on the date of such Common
Stock Distribution.

                  If any Common Stock Distribution shall require an adjustment
to the Exercise Price pursuant to the foregoing provisions of this paragraph
(a), including by operation of

<PAGE>   8

paragraph (b) or (c) below, then, effective at the time such adjustment is made,
the number of shares of Common Stock  subject to purchase  upon exercise of this
Warrant shall be increased to a number  determined by multiplying  the number of
shares of Common Stock subject to purchase  immediately before such Common Stock
Distribution by a fraction, the numerator of which shall be the number of shares
of Common Stock outstanding immediately after giving effect to such Common Stock
Distribution  and the  denominator  of which  shall be the sum of the  number of
shares of Common Stock  outstanding  immediately  before  giving  effect to such
Common Stock  Distribution  (both  calculated on a Fully Diluted Basis) plus the
number of shares of Common Stock which the aggregate  consideration  received by
the Company with respect to such Common Stock Distribution would purchase at the
Fair  Market  Value of the Company per share of  outstanding  Common  Stock on a
Fully Diluted Basis on the date of such Common Stock Distribution (before giving
effect to such Common Stock Distribution).  In computing  adjustments under this
paragraph,  fractional  interests in Common Stock shall be taken into account to
the nearest one-thousandth of a share.

                  The provisions of this paragraph (a), including by operation
of paragraph (b) or (c) below, shall not operate to increase the Exercise Price
or reduce the number of shares of Common Stock subject to purchase upon exercise
of this Warrant.

                  (b) If the Company shall issue, sell, distribute or otherwise
grant in any manner (including by assumption) any rights to subscribe for or to
purchase, or any warrants or options for the purchase of Common Stock or any
stock or securities convertible into or exchangeable for Common Stock (such
rights, warrants or options being herein called "Options" and such convertible
or exchangeable stock or securities being herein called "Convertible
Securities"), whether or not such Options or the rights to convert or exchange
any such Convertible Securities in respect of such Options are immediately
exercisable, 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 in respect of such Options (determined by dividing (i) the aggregate
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 Options to acquire Convertible Securities, the minimum
aggregate amount of additional consideration, if any, payable upon the issuance
or sale of such Convertible Securities and upon the conversion or exchange
thereof, by (ii) the total maximum number of shares of Common Stock issuable
upon the exercise of such Options or upon the conversion or exchange of all such
Convertible Securities issuable upon the exercise of such Options) shall be less
than the Exercise Price then in effect or less than the Fair Market Value of the
Company per share of outstanding Common Stock on a Fully Diluted Basis on the
date of granting such Options (before giving effect to such grant), then, for
purposes of paragraph (a) above, 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 have been issued as of the date of
granting of such Options and thereafter shall be deemed to be outstanding and
the Company shall be deemed to have received as consideration of such price per
share, determined as provided above, therefor. Except as otherwise provided in
paragraph (d) below, no additional adjustment of the Exercise Price shall be
made upon the actual exercise of such Options or upon conversion or exchange of
such Convertible Securities.

                  (c) If the Company shall issue, sell or otherwise distribute
(including by assumption) any Convertible Securities, whether or not the rights
to exchange or convert thereunder are immediately exercisable, and the price per
share for which Common Stock is issuable upon such conversion or exchange
(determined by dividing (i) the aggregate amount

<PAGE>   9

received or receivable by the Company as consideration for the issuance, sale or
distribution 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 (ii) the total maximum number of shares of Common Stock
issuable  upon the  conversion or exchange of all such  Convertible  Securities)
shall be less  than the  Exercise  Price  then in  effect  or less than the Fair
Market  Value of the Company per share of  outstanding  Common  Stock on a Fully
Diluted Basis on the date of such issuance,  sale or distribution (before giving
effect to such issuance, sale or distribution),  then, for purposes of paragraph
(a) above,  the total  maximum  number of shares of Common Stock  issuable  upon
conversion  or exchange of all such  Convertible  Securities  shall be deemed to
have been issued as of the date of the issuance,  sale or  distribution  of such
Convertible  Securities and thereafter shall be deemed to be outstanding and the
Company shall be deemed to have received as consideration  such price per share,
determined  as  provided  above,  therefor.  Except  as  otherwise  provided  in
paragraph  (d) below,  no additional  adjustment of the Exercise  Price shall be
made upon the actual conversion or exchange of such Convertible Securities.

                  (d) If (i) the purchase price provided for in any Option
referred to in paragraph (b) above or the additional consideration, if any,
payable upon the conversion or exchange of any Convertible Securities referred
to in paragraph (b) or (c) above or the rate at which any Convertible Securities
referred to in paragraph (b) or (c) above are convertible into or exchangeable
for Common Stock shall change at any time (other than under or by reason of
provisions designed to protect against dilution upon an event which results in a
related adjustment pursuant to this Article IV), or (ii) any of such Options or
Convertible Securities shall have terminated, lapsed or expired, the Exercise
Price then in effect shall forthwith be readjusted to the Exercise Price which
would then be in effect, and the number of shares of Common Stock then subject
to purchase upon exercise of the Warrant shall be readjusted to the number of
shares of Common Stock which would then be subject to purchase upon exercise of
this Warrant (in each case effective only with respect to any exercise of this
Warrant after such readjustment), had the adjustment made upon the issuance,
sale, distribution or grant of such Options or Convertible Securities been made
based upon such changed purchase price, additional consideration or conversion
rate, as the case may be (in the case of any event referred to in clause (i) of
this paragraph (d)) or had such adjustment not been made (in the case of any
event referred to in clause (ii) of this paragraph (d)).

                  (e) If the Company shall pay a dividend or make any other
distribution upon any capital stock of the Company payable in Common Stock,
Options or Convertible Securities, then, for purposes of paragraph (a) above,
such Common Stock, Options or Convertible Securities shall be deemed to have
been issued or sold without consideration.

                  (f) If any shares of Common Stock, Options or Convertible
Securities shall be issued, sold or distributed for cash, the consideration
received therefor shall be deemed to be the gross amount received by the Company
therefor. If any shares of Common Stock, Options or Convertible Securities shall
be issued sold or distributed for a consideration other than cash, the amount of
the consideration other than cash received by the Company shall be deemed to be
the Fair Market Value of such consideration, after deduction of any expenses
incurred in connection therewith. If any shares of Common Stock, Options or
Convertible Securities shall be issued in connection with any merger in which
the Company is the surviving corporation, the amount of consideration therefor
shall be deemed to be the Fair Market Value of such portion of the assets and
business of the non-surviving corporation as shall be attributable to such
Common Stock, Options or Convertible Securities, as the case may be. If any
Options shall be issued in connection with the issuance and sale of other
securities of the Company, together comprising

<PAGE>   10

one integral transaction in which no specific consideration is allocated to such
Options by the parties thereto, such Options shall be deemed to have been issued
without consideration.

                  4.4. Special Dividends. If the Company shall issue or
distribute to any holder or holders of shares of Common Stock evidences of
indebtedness, any other securities of the Company or any cash, property or other
assets (excluding a Common Stock Reorganization or a Common Stock Distribution),
whether or not accompanied by a purchase, redemption or other acquisition of
shares of Common Stock (any such nonexcluded event being herein called a
"Special Dividend"), (a) the Exercise Price shall be decreased, effective
immediately after the effective date of such Special Dividend, to a price
determined by multiplying the Exercise Price then in effect by a fraction, the
numerator of which shall be the Fair Market Value of the Company per share of
outstanding Common Stock as of such effective date less any cash and the then
Fair Market Value of any evidences of indebtedness, securities or property or
other assets issued or distributed in such Special Dividend with respect to one
share of Common Stock, and the denominator of which shall be such Fair Market
Value per share and (b) the number of shares of Common Stock subject to purchase
upon exercise of this Warrant shall be increased to a number determined by
multiplying the number of shares of Common Stock subject to purchase immediately
before such Special Dividend by a fraction, the numerator of which shall be the
Exercise Price in effect immediately before such Special Dividend and the
denominator of which shall be the Exercise Price in effect immediately after
such Special Dividend. A reclassification of Common Stock (other than a change
in par value, or from par value to no par value or from no par value to par
value) into shares of Common Stock and shares of any other class of stock shall
be deemed a distribution by the Company to the holders of such Common Stock of
such shares of such other class of stock and, if the outstanding shares of
Common Stock shall be changed into a larger or smaller number of shares of
Common Stock as part of such reclassification, a Common Stock Reorganization.

                  4.5. Capital Reorganizations. If there shall be any
consolidation or merger to which the Company is a party, other than a
consolidation or a merger of which the Company is the continuing corporation and
which does not result in any reclassification of, or change (other than a Common
Stock Reorganization) in, outstanding shares of Common Stock, or any sale or
conveyance of the property of the Company as an entirety or substantially as an
entirety, or any recapitalization of the Company (any such event being called a
"Capital Reorganization"), then, effective upon the effective date of such
Capital Reorganization, the Holder shall no longer have the right to purchase
Common Stock, but shall have instead the right to purchase, upon exercise of
this Warrant, the kind and amount of shares of stock and other securities and
property (including cash) which the Holder would have owned or have been
entitled to receive pursuant to such Capital Reorganization if this Warrant had
been exercised immediately prior to the effective date of such Capital
Reorganization. As a condition to effecting any Capital Reorganization, the
Company or the successor or surviving corporation, as the case may be, shall
execute and deliver to each Warrantholder and to the Warrant Agency an agreement
as to the Warrantholders' rights in accordance with this Section 4.5, providing,
to the extent of any right to purchase equity securities hereunder, for
subsequent adjustments as nearly equivalent as may be practicable to the
adjustments provided for in this Article IV. The provisions of this Section 4.5
shall similarly apply to successive Capital Reorganizations.

                  4.6. Adjustment Rules. Any adjustments pursuant to this
Article IV shall be made successively whenever an event referred to herein shall
occur, except that, notwithstanding any other provision of this Article IV, no
adjustment shall be made to the number of shares of Common Stock to be delivered
to each Holder (or to the Exercise Price) if such adjustment represents less
than one percent (1%) of the number of shares previously required to be so

<PAGE>   11

delivered, but any lesser adjustment shall be carried forward and shall be made
at the time and together with the next subsequent adjustment which together with
any adjustments so carried forward shall amount to one percent (1%) or more of
the number of shares to be so delivered. No adjustment shall be made pursuant to
this Article IV in respect of the issuance from time to time of shares of Common
Stock upon the exercise of any of the Warrants. If the Company shall take a
record of the holders of its Common Stock for any purpose referred to in this
Article IV, then (i) such record date shall be deemed to be the date of the
issuance, sale, distribution or grant in question and (ii) if the Company shall
legally abandon such action prior to effecting such action, no adjustment shall
be made pursuant to this Article IV in respect of such action.

                  4.7. Proceedings Prior to Any Action Requiring Adjustment. As
a condition precedent to the taking of any action which would require an
adjustment pursuant to this Article IV, the Company shall take any action which
may be necessary, including obtaining regulatory approvals or exemptions, in
order that the Company may thereafter validly and legally issue as fully paid
and nonassessable all shares of Common Stock which the holders of Warrants are
entitled to receive upon exercise thereof.

                  4.8. Notice of Adjustment. Not less than 10 nor more than 30
days prior to the record date or effective date, as the case may be, of any
action which requires or might require an adjustment or readjustment pursuant to
this Article IV, the Company shall give notice to each Warrantholder of such
event, describing such event in reasonable detail and specifying the record date
or effective date, as the case may be, and, if determinable, the required
adjustment and the computation thereof. If the required adjustment is not
determinable at the time of such notice, the Company shall give notice to each
Warrantholder of such adjustment and computation promptly after such adjustment
becomes determinable.

                                    ARTICLE V

                              PURCHASE OF WARRANTS

                  5.1. Purchase of Warrants by the Company. The Company shall
have the obligation to purchase or otherwise acquire Warrants at such times, in
such manner and for such consideration as set forth below.

                  5.2. Put Rights.  The Holder shall:

                  (a) at any time and from time to time on or after the earlier
                  of July 23, 2001 or the date on which a Triggering Event shall
                  occur, have the right (the "Put Right") to sell back to the
                  Company its Warrant Shares at the greater of (i) the Fair
                  Market Value of all such Warrant Shares or (ii) the cash
                  amount determined by application of the following formula:

                  [(EBITDA  times  5) - Term  Debt -  Minimum  Revolving  Debt -
                  Preferred Stock + Cash] times Applicable Percentage

                  (b) Within thirty (30) days of the Company's receipt of
                  notification from the Holder that it wishes to exercise its
                  Put Right (the "Put Notification"), the Company shall
                  repurchase such number of Warrant Shares then held by the
                  Holder as shall be specified in the Put Notification (the
                  "Repurchase Date"). The repurchase price for each Share (the
                  "Repurchase Price") shall be paid in cash on

<PAGE>   12
                  the  Repurchase  Date or, at the option of the Holder,  in the
                  form  of an unsecured  promissory  note  in  form reasonably
                  satisfactory to the Holder maturing  in one year and bearing
                  interest at the rate of twelve percent (12%) per annum.

                  (c) Surrender the certificate(s) representing Warrant Shares
                  being repurchased to the Company and thereupon the Repurchase
                  Price for such Warrant Shares shall be paid to the order of
                  the person whose name appears on such certificate(s) and each
                  surrendered certificate shall be canceled and retired.

                  5.3.  Termination of Put Rights;  Limitation.  Notwithstanding
anything  herein to the contrary,  (a) the Put Rights shall  terminate  upon the
closing of a Qualified  IPO, and (b) the Holder shall have the right to exercise
no more than three (3) Put Rights.

                  5.4.   Cancellation  of  Warrants.   All  Warrants  purchased,
redeemed or otherwise  acquired by the Company  shall  thereupon be canceled and
retired. The Warrant Agency shall cancel any Warrant surrendered for exercise or
registration  of transfer or exchange and deliver such canceled  Warrants to the
Company.

                                   ARTICLE VI
