     Section 2. Common Stock: Issuance of Options. (a) Subject to the terms and
conditions hereof, Holding hereby agrees to issue and sell to the Employee
Stockholder, and the Employee Stockholder hereby agrees to subscribe for the
number of shares of Common Stock set forth opposite such Employee Stockholder's
name on the signature page hereof at a price of $0.50 per share in cash. In
addition, WMC agrees to guarantee a loan to be made by a bank designated by WMC
to the Employee Stockholder in order to enable the Employee Stockholder to
purchase the Assisted Shares set forth on the signature pages hereof at a
purchase price of $.50 per share in cash and on such other terms and conditions
as are determined by WMC. The closing of such purchase and sale shall take place
at such time and place as is notified to the Employee Stockholder (the "Closing
Date"). On or prior to the Closing Date, the Employee Stockholder shall deliver
to Holding a check in an amount equal to the purchase price for the Common
Stock. Holding shall have no obligation to sell any shares of Common Stock to
any person who (i) is a resident or citizen of a state or other jurisdiction in
which the sale of the Common Stock to him or her would constitute a violation of
the securities or "blue sky" laws of such jurisdiction or (ii) is not an
employee of WMC on the date hereof.

     (b) Subject to the terms and conditions hereinafter set forth and upon and
as of the Closing Date, WMC shall issue to the Employee Stockholder the number
of Options set forth opposite the Employee Stockholder's name on the signature
page hereof and the Parties shall execute and deliver to each other copies of
the Non-Qualified Option Agreement concurrently with the issuance of the
Options.

     Section 3. Employee Stockholder's Representations, Warranties and
Agreements. (a) The Employee Stockholder agrees and acknowledges that he or she
will not, directly or indirectly, offer, transfer, sell, assign, pledge,
hypothecate or otherwise dispose of (any such act being referred to herein as a
"transfer") any shares of Common Stock (whether purchased on the Closing Date or
acquired at any time thereafter) and, at the time of exercise, the Class A
common stock of WMC issuable upon exercise of the Options (the "Option Stock"
and, collectively with the Common Stock and the Assisted Shares, the "Stock")
unless such transfer complies with Section 4 of this Agreement. If the Employee
Stockholder is an Affiliate, the Employee Stockholder also agrees and
acknowledges that he or she will not transfer any shares of Stock unless:

          (i) the transfer is pursuant to an effective registration statement
     under the Securities Act, and in compliance with applicable provisions of
     state securities laws, (if otherwise permitted under the terms set forth
     herein) or
<PAGE>

                                                                               5

          (ii) (A) counsel for the Employee Stockholder (which counsel shall be
     reasonably acceptable to WMC or Holding, as the case may be) shall have
     furnished WMC or Holding, as the case may be, with an opinion, satisfactory
     in form and substance to WMC or Holding, as the case may be, that no such
     registration is required because of the availability of an exemption from
     registration under the Securities Act and (B) if the Employee Stockholder
     is a citizen or resident of any country other than the United States, or
     the Employee Stockholder desires to effect any transfer in any such
     country, counsel for the Employee Stockholder (which counsel shall be
     reasonably satisfactory to WMC, in the case of Option Stock, or Holding, in
     the case of Common Stock) shall have furnished WMC or Holding, as the case
     may be, with an opinion or other advice satisfactory in form and substance
     to WMC or Holding, as the case may be, to the effect that such transfer
     will comply with the securities laws of such jurisdiction.

     Notwithstanding the foregoing, WMC and Holding acknowledge and agree that
any of the following transfers are deemed to be in compliance with the
Securities Act and this Agreement and no opinion of counsel is required in
connection therewith: (x) a transfer made pursuant to Section 9 hereof, (y) a
transfer upon the death of the Employee Stockholder to his executors,
administrators, testamentary trustees, legatees or beneficiaries or a transfer
to the executors, administrators, testamentary trustees, legatees or
beneficiaries of a person who has become a holder of Stock in accordance with
the terms of this Agreement, provided that it is expressly understood that any
such transferee shall be bound by the provisions of this Agreement and (z) a
transfer made after the Closing Date in compliance with the federal securities
laws to a trust or custodianship the beneficiaries of which may include only the
Employee Stockholder, his spouse or his lineal descendants (an "Employee
Stockholder's Trust"), provided that any such transfer under (x), (y) or (z) is
made expressly subject to this Agreement and that the transferee agrees in
writing to be bound by the terms and conditions hereof. The transferees of Stock
purchase to (x), (y) or (z) who agree to be bound by the terms of this Agreement
are referred to as "Permitted Transferees",

     (b) The certificate (or certificates) representing the Option Stock shall
bear the following legend:

     "THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE TRANSFERRED, SOLD,
     ASSIGNED, PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF UNLESS SUCH
     TRANSFER, SALE, ASSIGNMENT, PLEDGE, HYPOTHECATION OR OTHER DISPOSITION
     COMPLIES WITH THE PROVISIONS OF THE SUBSCRIPTION AND EMPLOYEE STOCKHOLDER'S
     AGREEMENT DATED AS OF DECEMBER __, 1999 BETWEEN WESTERN MULTIPLEX
     CORPORATION ("WMC"), WMC HOLDING CORP., THE EMPLOYEE STOCKHOLDER NAMED ON
     THE FACE HEREOF AND RIPPLEWOOD PARTNERS, L.P. (A COPY OF WHICH IS ON FILE
     WITH THE SECRETARY OF WMC)."

     (c) The certificate (or certificates) representing the Common Stock shall
bear the following legend:

     "THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE TRANSFERRED,
<PAGE>

                                                                               6

     SOLD, ASSIGNED, PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF UNLESS SUCH
     TRANSFER, SALE, ASSIGNMENT, PLEDGE, HYPOTHECATION OR OTHER DISPOSITION
     COMPLIES WITH THE PROVISIONS OF THE SUBSCRIPTION AND EMPLOYEE STOCKHOLDER'S
     AGREEMENT DATED AS OF DECEMBER __, 1999 BETWEEN WESTERN MULTIPLEX
     CORPORATION, WMC HOLDING CORP. ("HOLDING"), THE EMPLOYEE STOCKHOLDER NAMED
     ON THE FACE HEREOF AND RIPPLEWOOD PARTNERS, L.P. (A COPY OF WHICH IS ON
     FILE WITH THE SECRETARY OF HOLDING)."


     (d) The Employee Stockholder acknowledges that he or she has been advised
that (i) a restrictive legend in the form heretofore set forth shall be placed
on the certificates representing the Stock and (ii) a notation shall be made in
the appropriate records of WMC and/or Holding, as the case may be, indicating
that the Stock is subject to restrictions on transfer and appropriate stop-
transfer restrictions will be issued to the applicable transfer agent with
respect to the Stock. If the Employee Stockholder is an Affiliate, the Employee
Stockholder also acknowledges that (1) the Stock must be held indefinitely and
the Employee Stockholder must continue to bear the economic risk of the
investment in the Stock unless it is subsequently registered under the
Securities Act or an exemption from such registration is available, (2) when and
if shares of Stock may be disposed of without registration in reliance on Rule
144 of the rules and regulations promulgated under the Securities Act, such
disposition can be made only in limited amounts in accordance with the terms and
conditions of such Rule and (3) if the Rule 144 exemption is not available,
public sale without registration will require compliance with some other
exemption under the Securities Act.

     (e)(i) If any shares of Option Stock are to be disposed of in accordance
with Rule 144 under the Securities Act or otherwise, the Employee Stockholder
shall promptly notify WMC of such intended disposition and shall deliver to WMC
at or prior to the time of such disposition such documentation as WMC may
reasonably request in connection with such sale and, in the case of a
disposition pursuant to Rule 144, shall deliver to WMC an executed copy of any
notice of Form 144 required to be filed with the Securities and Exchange
Commission (the "SEC").

     (ii) If any shares of Common Stock are to be disposed of in accordance with
Rule 144 under the Securities Act or otherwise, the Employee Stockholder shall
promptly notify Holding of such intended disposition and shall deliver to
Holding at or prior to the time of such disposition such documentation as
Holding may reasonably request in connection with such sale and, in the case of
a disposition pursuant to Rule 144, shall deliver to Holding an executed copy of
any notice of Form 144 required to be filed with the SEC.

     (f) The Employee Stockholder agrees that, if any shares of WMC Common Stock
are offered to the public pursuant to an effective registration statement under
the Securities Act (other than registration of securities issued under an
employee plan), the Employee Stockholder will not
<PAGE>

                                                                               7

effect any public sale or distribution of any shares of Stock not covered by
such registration statement from the time of the receipt of a notice from WMC
that WMC has filed or imminently intends to file such registration statement to,
or within 180 days after, the effective date of such registration statement,
unless otherwise agreed to in writing by WMC.

     (g) The Employee Stockholder represents and warrants that (i) he has
received and reviewed the document(s) comprising the Confidential Information
Memorandum, dated December 21, 1999 (the "Confidential Information Memorandum"),
relating to the Stock and Options, and the documents referred to therein,
certain of which documents set forth the rights, preferences, and restrictions
relating to the Stock and Options, and (ii) he or she has been given the
opportunity to obtain any additional information or documents and to ask
questions and receive answers about such information, WMC, Holding and the
business and prospects of WMC and Holding which he or she deems necessary to
evaluate the merits and risks related to his or her investment in the Stock, and
to verify the Confidential Information Memorandum and the information contained
in the document(s) received as indicated in this Section 3(g), and he or she has
relied solely on such information.

     (h) The Employee Stockholder further represents and warrants that (i) his
or her financial condition is such that he or she can afford to bear the
economic risk of holding the Stock for an indefinite period of time and has
adequate means for providing for his or her current needs and personal
contingencies, (ii) he or she can afford to suffer a complete loss of his or her
investment in the Stock, (iii) he or she understands and has taken cognizance of
all risk factors related to the purchase of Stock (including, but not limited
to, those set forth in the Confidential Information Memorandum) and (iv) his or
her knowledge and experience in financial and business matters are such that he
is capable of evaluating the merits and risks of his or her purchase of Stock as
contemplated by this Agreement.

     (i) The Employee Stockholder has executed and delivered to WMC the
Employment, Confidential Information and Invention Assignment Agreement.

     Section 4. Restrictions on Transfer. Except for transfers to Permitted
Transferees permitted by clauses (x), (y) and (z) of Section 3(a) or a sale of
shares of Stock pursuant to Section 9 of this Agreement, the Employee
Stockholder agrees that he or she will not transfer any shares of Stock at any
time prior to the third anniversary of the Closing Date (the "Restricted
Period"). The Employee Stockholder further agrees not to transfer any Options,
except as expressly provided by this Agreement. No transfer in violation of this
Section 4 shall be made or recorded on the books of WMC or Holding and any such
transfer shall be void and of no effect.

     Section 5. Right of First Refusal. If, following the Restricted Period, but
prior to a Public Offering, the Employee Stockholder or any Permitted Transferee
receives a bona fide offer to purchase any or all of his shares of Stock (the
"Offer") from a third party (the "Offeror") which the Employee Stockholder or
any such Permitted Transferee wishes to accept, the Employee Stockholder shall
cause the Offer to be reduced to writing and shall notify WMC, in the case of
<PAGE>

                                                                               8

an Offer to purchase Option Stock, or Holding, in the case of an Offer to
purchase Common Stock, in writing of his or her wish to accept the Offer. The
Employee Stockholder's notice shall contain an irrevocable offer to sell such
shares of Stock to WMC or Holding, as the case may be (in the manner set forth
below), at a purchase price equal to the price contained in, and on the same
terms and conditions of, the Offer, and shall be accompanied by a copy of the
Offer (which shall identify the Offeror). At any time within 30 days after the
date of the receipt by WMC or Holding of the Employee Stockholder's notice, WMC
or Holding, as the case may be, shall have the right and option to elect to
purchase, or to arrange for a third party (including WMC, Holding or Ripplewood)
to elect to purchase, all of the shares of Stock covered by the Offer either (i)
at the same price and on the same terms and conditions as the Offer or (ii) if
the Offer includes any consideration other than cash, then at the sole option of
WMC or its designee or Holding or its designee, as the case may be, at the
equivalent all cash price, determined in good faith by WMC's or Holding's, as
the case may be, Board of Directors, by delivering notice of such election to
the Employee Stockholder within such 30-day period. If WMC or Holding, as the
case may be, exercises such right, it shall deliver a certified bank check or
checks in the appropriate amount (and any such non-cash consideration to be
paid) to the Employee Stockholder or any Permitted Transferee (as the case may
be) at the principal office of WMC against delivery of certificates or other
instruments representing the shares of Stock so purchased, appropriately
endorsed by the Employee Stockholder and the Permitted Transferee, within 10
business days following its election. If at the end of the 30-day period, WMC or
Holding has not notified the Employee Stockholder of its election in the manner
set forth above, the Employee Stockholder and the Permitted Transferee may,
during the succeeding 60-day period, sell not less than all of the shares of
Stock covered by the Offer to the Offeror at a price and on terms no less
favorable to the Employee Stockholder or the Permitted Transferee (as the case
may be) than those contained in the Offer. Promptly after such sale, the
Employee Stockholder or the Permitted Transferee (as the case may be) shall
notify WMC or Holding, as the case may be, of the consummation thereof and shall
furnish such evidence of the completion and time of completion of such sale and
of the terms thereof as may reasonably be requested by WMC or Holding. If, at
the end of 60 days following the expiration of the 30-day period for WMC or
Holding to purchase the Stock, the Employee Stockholder or the Permitted
Transferee (as the case may be) has not completed the sale of such shares of
Stock as aforesaid, all the restrictions on sale, transfer or assignment
contained in this Agreement shall again be in effect with respect to such shares
of Stock.

     Section 6. Call Rights. (a) If, prior to the end of the Restricted Period,
(x) the Employee Stockholder's active employment with WMC (and/or, if
applicable, its subsidiaries) is terminated by WMC for Cause, (y) the
beneficiaries of an Employee Stockholder's Trust shall include any person or
entity other than the Employee Stockholder, his spouse or lineal descendants, or
(z) the Employee Stockholder (and any Permitted Transferees) shall effect a
transfer of any shares of Stock other than as permitted in this Agreement, then:

          (i) Holding shall have the right to purchase all or any portion of the
     Common Stock (other than the Assisted Shares) then held by the Employee
     Stockholder (and any Permitted Transferees) for a purchase price equal to
     the lesser of the Fair Market Value per share and the Book Value per

                                                                               9

     share;

          (ii) WMC shall have the right to purchase all or any portion of the
     Option Stock then held by the Employee Stockholder (and any Permitted
     Transferees) for a purchase price equal to the lesser of the Option Price
     and the Book Value per Option; and

          (iii) All Options shall terminate without any payment.

          (iv) Holding shall have the right to purchase all or any portion of
     the Assisted Shares then held by the Employee Stockholder (and any
     Permitted Transferees) at a price equal to the lesser of (a) the purchase
     price per share ($.50) and (b) the Book Value per share.

     (b) If, prior to the expiration of the Restricted Period, the Employee
Stockholder's active employment with WMC is terminated without Cause or if the
Employee Stockholder quits or for Good Reason, then WMC may purchase all or any
portion of the Assisted Shares then held by the Employee Stockholder (and any
Permitted Transferees) at a price equal to the Fair Market Value per share.

     (c) If, prior to the expiration of the Restricted Period, the Employee
Stockholder quits without Good Reason, then WMC will have the right to purchase
all or any portion of the Assisted Shares then held by the Employee Stockholder
(and any Permitted Transferees) for the lesser of (a) the purchase price per
share and the Fair Market Value per share.

     (d) If, prior to the expiration of the Restricted Period, the Employee
Stockholder's active employment with WMC (and/or, if applicable, its
subsidiaries) ceases for any reason other than termination by WMC for Cause or
termination due to the death or permanent disability (including if the Employee
Stockholder quits or resigns), then:

          (i) Holding shall have the right to purchase all or any portion of the
     Common Stock then held by the Employee Stockholder (and any Permitted
     Transferees) for a purchase price equal to the Fair Market Value per share;

          (ii) WMC shall have the right to purchase all or any portion of vested
     Options then held by the Employee Stockholder (and any Permitted
     Transferees) at a purchase price equal to the Fair Market Value per vested
     Option less the Option Price; provided that, if WMC exercises such
     repurchase right with respect to any Option that would have a repurchase
     price under this clause (b)(ii) of less than the Option Price at the time
     of such exercise, then such Options shall be canceled without any payment;

          (iii) WMC shall have the right to purchase all or any portion of the
     Option Stock then held by the Employee Stockholder (and any Permitted
     Transferees) at a purchase price equal to the Fair

                                                                              10

     Market Value per share; and

          (iv) all unvested Options shall terminate without any payment
     therefor.

     (e) If the purchaser dies or becomes permanently disabled while still an
employee of WMC (and/or, if applicable, its subsidiaries), then (i) Holding may
purchase all or any portion of the shares of Common Stock then held by the
Employee Stockholder (and any Permitted Transferees) at a purchase price equal
to the Fair Market Value per share; and (ii) WMC may purchase all of the Option
Stock then held by the Employee Stockholder (and any Permitted Transferees) at a
purchase price equal to the Fair Market Value per share less the Option Price
per share.

     (f) The price at which Stock or Options are purchased by WMC or Holding
pursuant to Sections 5(a), 5(b) and 5(c) is referred to as the "Purchase Price".
Any right to repurchase pursuant to Sections 5(a), 5(b) and 5(c) is referred to
as a "Call Right".

     (g) Absent the extension of a Call Right on account of a default under any
indebtedness agreement or violation of a statute as described in Section 5(f)
below, WMC or Holding, as the case may be, shall have a period of sixty (60)
days from the date of the event giving rise to the Call Right (or if later,
after the discovery of an impermissible transfer) in which to give notice in
writing to the Employee Stockholder of its election to exercise its Call Rights
pursuant to Sections 5(a), 5(b) or 5(c) (a "Call Notice"); provided that, in the
case of the Employee Stockholder's permanent disability, such 60-day exercise
period shall be extended to twelve (12) months after the event giving rise to
the Call Right; and provided further, that any Call Right available in such case
must be exercised within such 12-month period.

     (h) A Call Right shall be extended if WMC or Holding is, or would be as a
result of the payment of the Purchase Price, in default under any indebtedness
agreement or in violation of a statute. Any Call Right may be delayed upon such
default or violation of twelve (12) months thereafter; provided however, that,
if in connection with an event giving rise to a Call Right pursuant to Section
5(b), the exercise by WMC or Holding, as the case may be, of its Call Right is
delayed by reason of such default, then and only then will exercisable Options
be deemed to continue to be exercisable for the purposes of the purchase
pursuant to the Call Right and the Purchase Price for the Stock and Options will
be the higher of: (i) the Purchase Price determined as of the month end prior to
termination and (ii) the Purchase Price determined as of the month end prior to
the delayed purchase. In connection with a termination for Cause or any other
event giving rise to a Call Right pursuant to Section 6(a), the Purchase Price
for the Stock and Options shall be the lesser of (i) the Purchase Price
determined as of the month end prior to termination and (ii) the Purchase Price
determined as of the month end prior to the delayed purchase. Any Call Right may
only be delayed upon such default or violation for twelve (12) months
thereafter.

     (i) The completion of any purchase pursuant to this Section 5 shall take
place at the principal office of WMC on the tenth business day after the giving
of the Call Notice. The applicable
<PAGE>

                                                                              11

Purchase Price shall be paid by delivery to the Employee Stockholder (or the
Permitted Transferee, as the case may be) of a certified bank check or checks in
the appropriate amount payable to the order of the Employee Stockholder against
delivery of certificates or other instruments representing the Stock so
purchased and appropriate documents canceling the Options so terminated,
appropriately endorsed or executed by the Employee Stockholder (or the Permitted
Transferee, as the case may be) or the Employee Stockholder's or Permitted
Transferee's authorized representative.

     (j) Subject to Section 5(f), the Purchase Price shall be calculated as of
the last day of the month preceding the month in which the event giving rise to
the Call Right occurs.

     (k) In determining the Purchase Price, appropriate adjustments shall be
made for any share dividends, splits, combinations, recapitalizations or any
other adjustment in the number of outstanding common stock in order to maintain,
as nearly as practicable, the intended operation of the provisions of this
Section 6.

     Section 7. Tag-Along Rights. (a) If prior to a Public Offering Ripplewood,
("Ripplewood") desires to transfer a majority or all of its shares of common
stock of Holding ("Holding Stock") to a prospective third party purchaser other
than to a Permitted Ripplewood/ Holding Transferee, Ripplewood shall, as a
condition to such transfer, (A) provide a notice to the Employee Stockholder in
writing (a "Tag-Along Notice") of the material terms of the proposed transfer at
least 14 days prior to such transfer and (B) permit the Employee Stockholder (or
cause the Employee Stockholder to be permitted) to sell (either to the
prospective transferee or to another financially reputable transferee reasonably
acceptable to the Employee Stockholder) the same portion of its outstanding
shares of Common Stock and Option Stock on the same terms and conditions,
subject to the same agreements and at the same price as the sale by Ripplewood
(in each case subject to Section 7(c)), which sale shall take place on the date
Ripplewood's shares of Holding Stock (or such portion) are transferred to such
transferee. To calculate the number of outstanding shares of Common Stock and
Option Stock that the Employee Stockholder can sell for the purposes of this
Section 7(a), WMC and Holding shall be treated as a single entity such that the
Employee Stockholder will be able to sell the product of (x) a fraction, the
numerator of which is the number of shares of common stock of Holding being sold
by Ripplewood, and the denominator of which is the total number of shares of
common stock of Holding owned by Ripplewood, multiplied by (y) the total number
of shares of Common Stock and Option Stock owned by the Employee Stockholder
(e.g., if Ripplewood is selling 75% of its interest in common stock of Holding,
the Employee Stockholder will be able to include 75% of its total ownership of
Common Stock and Option Stock, calculated as though WMC and Holding are a single
entity). Should the Employee Stockholder exercise his or her rights pursuant to
this Section 7(a), the Employee Stockholder shall be required to transfer Common
Stock and Option Stock held by him or her in the following order of priority:
(1) first, shares of Common Stock (until the Employee Stockholder holds no
shares of Common Stock), and (2) second, Option Stock (until the Employee
Stockholder holds no shares of Option Stock). The Employee Stockholder shall
have ten days from the date of receipt of a Tag-Along Notice to exercise his or
<PAGE>

                                                                              12

her right to sell pursuant to this Section 7(a) by delivering written notice to
Ripplewood of his or her intent to exercise such right. The Employee
Stockholder's right to sell in such transaction pursuant to the above shall
terminate if not exercised within such ten-day period.

     (b) If Holding sells a majority or all of its interest in WMC to a
prospective third party purchaser other than a Permitted Ripplewood/Holding
Transferee, Holding shall, as a condition to such transfer, (A) provide a notice
to the Employee Stockholder in writing (a "WMC Sale Tag-Along Notice") of the
material terms of the proposed transfer at least 14 days prior to such transfer
and (B) permit the Employee Stockholder (or cause the Employee Stockholder to be
permitted) to sell (either to the prospective transferee or to another
financially reputable transferee reasonably acceptable to the Employee
Stockholder) a number of its outstanding shares of Option Stock equal to (x) the
percentage of the outstanding shares of WMC Common Stock owned by Holding that
are being sold by Holding (e.g., if there are 2,000 shares of WMC Common Stock
outstanding of which Holding owns 1,800 shares and Holding is selling 180
shares, the percentage under this clause (x) will be 10%) multiplied by (y) the
number of shares of Option Stock owned by the Employee Stockholder. Subject to
Section 7(c), any such sale shall be on the same terms and conditions, subject
to the same agreements and at the same price as the sale by Holding, which sale
shall take place on the date Holding's shares of WMC Common Stock (or such
portion) are transferred to such transferee (or transferees). The Employee
Stockholder shall have ten days from the date of receipt of a WMC Sale Tag-Along
Notice to exercise his or her right to sell pursuant to this Section 7 by
delivering written notice to Holding of his or her intent to exercise such
right. The Employee Stockholder's right to sell in such transaction pursuant to
the above shall terminate if not exercised within such ten-day period.

     (c) The Employee Stockholder shall not have the right to transfer any
Options pursuant to this Section 7.

     Section 8. Drag-Along Rights. (i) If at any time Ripplewood desires to
transfer all or any portion of its shares of Holding Stock to any third party
purchaser(s), other than Permitted Ripplewood/Holding Transferees, or Holding
desires to transfer all or any portion of its shares of WMC Common Stock to any
third party purchaser(s), other than Permitted Ripplewood/Holding Transferees,
Ripplewood shall have the right to require that the Employee Stockholder and its
Permitted Transferees transfer the same portion of the Employee Stockholder's
and its Permitted Transferees' shares of Common Stock and Option Stock to such
third party purchaser(s) on the same terms and conditions, subject to the same
agreements and at the same price as the sale by Ripplewood. To calculate the
number of outstanding shares of Common Stock and Option Stock that the Employee
Stockholder and its Permitted Transferees can be required to sell pursuant to
this Section 8, WMC and Holding shall be treated as a single entity such that
the Employee Stockholder and its Permitted Transferees (considered as a single
stockholder for this purpose) can be required to sell the product of (x) a
fraction, the numerator of which is the number of shares of Holding Stock being
sold by Ripplewood, and the denominator of which is the total number of shares
of Holding Stock owned by Ripplewood, multiplied by (y) the total number of

                                                                              13

shares of Common Stock and Option Stock owned by the Employee Stockholder and
its Permitted Transferees (e.g. if Ripplewood is selling 75% of its interest in
Holding Stock, Ripplewood will have the right to require that the Employee
Stockholder and its Permitted Transferees transfer 75% of their total aggregate
ownership of Common Stock and Option Stock, calculated as though WMC and Holding
are a single entity). Should Ripplewood exercise its rights pursuant to this
Section 8, the Employee Stockholder and its Permitted Transferees shall be
required to transfer Common Stock and Option Stock held by them in the following
order of priority: (1) first, shares of Common Stock (until the Employee
Stockholder and its Permitted Transferees hold no shares of Common Stock), and
(2) second, Option Stock (until the Employee Stockholder and its Permitted
Transferees hold no Option Stock). Ripplewood shall provide a notice to the
Employee Stockholder in writing (a "Drag-Along Notice") of such sale at least 10
days prior to such transfer, and the Drag-Along Notice shall identify such third
party purchaser(s), all material terms of the sale and the date of closing. Upon
the closing of any sale by Ripplewood of all (or such portion) of its shares of
Holding Stock or any sale by Holding of WMC Common Stock, as described in a
Drag-Along Notice, such third party purchaser(s) shall pay to the Employee
Stockholder and/or its Permitted Transferees, as the case may be, the
consideration payable to the Employee Stockholder and/or its Permitted
Transferees, as the case may be, in connection with such sale of all (or such
portion) of its shares of Common Stock and Option Stock, and the Employee
Stockholder's and its Permitted Transferee's shares of Common Stock and Option
Stock (or such portion) shall be deemed transferred to such third party
purchaser(s).

     Section 9. Sale Participation Rights. At any time following the expiration
of the period ending 180-days after a Public Offering, the Employee Stockholder
and its Permitted Transferees will have the right to sell all or any portion of
the Stock held by such Employee Stockholder and its Permitted Transferees in any
registered offering of WMC Common Stock initiated by WMC, Holding or Ripplewood.
Such registration rights will be on customary terms and conditions (including,
without limitation, customary cut back and lock-up provisions) established in
good faith by WMC's or Holding's Board of Directors and Ripplewood and notified
to the Employee Stockholder and the Other Employee Stockholders.

     Section 10. Voting Agreement. (a) From and after the Closing Date, the
Employee Stockholder and its Permitted Transferees: (i) shall vote all of the
shares of Stock held by him, her or it (including, without limitation, shares
acquired after the date hereof) in the same manner as the shares of Holding held
by Ripplewood (in the case of Holding Stock) or Holding (in the case of WMC
Common Stock) are voted on all matters acted upon at any annual or special
meeting of Stockholders or by written consent in lieu of a meeting and (ii)
irrevocably constitutes and appoints the person who is at the time the Senior
Managing Director of Ripplewood Holdings (or his or her designee, with full
power of substitution) his proxy to vote all of the shares of Common Stock held
by the Employee Stockholder in the same manner as the shares of Holding Stock
held by Ripplewood and appoints the person who is at the time the Chief
Executive Officer of WMC (or his or her designee, with full power of
substitution) his proxy to vote all of the shares of Option Stock held by the
Employee Stockholder and its Permitted Transferees in the
<PAGE>

                                                                              14

same manner as the shares of WMC Common Stock held by Holding are voted on all
matters acted upon at any annual or special meeting of stockholders or by
written consent in lieu of a meeting; provided that this Section 10 shall be
inapplicable with respect to any matters which would both adversely affect the
rights of shares of Stock held by the Employee Stockholder (or its Permitted
Transferees) and treat the Employee Stockholder (or its Permitted Transferees)
differently from other holders of shares of WMC Common Stock or Holdings Stock
(it being understood that a conversion of Holding to a limited liability company
and a merger or other business combination of Holding and WMC will not be deemed
to adversely affect the rights of the Employee Stockholder (or its Permitted
Transferees) and the Employee Stockholder hereby agrees that his or her shares
of Common Stock will be voted in favor of any such action). The voting
agreements and proxies granted pursuant to this Section 10 are coupled with an
interest and shall be valid for the term of this Agreement. The Employee
Stockholder represents that he or she has not granted and is not party to any
proxy, voting trust or other agreement which in each case is inconsistent with
or conflicts with the provisions of this Agreement, and the Employee Stockholder
shall not grant any proxy or become a party to any voting trust or other
agreement which in each case is inconsistent with or conflicts with the
provisions of this Agreement.

     Section 11. Rights to Negotiate Repurchase Price. Nothing in this Agreement
shall be deemed to restrict or prohibit WMC or Holding from purchasing Stock or
Options from the Employee Stockholder or its Permitted Transferees (or any other
Employee Stockholder), at any time, upon such terms and conditions, and for such
price, as may be mutually agreed upon between the Parties, whether or not at the
time of such purchase circumstances exist which specifically grant WMC or
Holding the right to purchase Stock or Options.

     Section 12. Covenant Regarding 83(b) Election. Except as WMC may otherwise
agree in writing, the Employee Stockholder hereby covenants and agrees that he
will make an election provided pursuant to Treasury Regulation 1.83-2 with
respect shares of Option Stock to be acquired upon each exercise of the Employee
Stockholder's Options; and the Employee Stockholder further covenants and agrees
that he or she will furnish WMC with copies of the forms of election the
Employee Stockholder files and within 30 days after each exercise of the
Employee Stockholder Options and with evidence that each such election has been
filed in a timely manner.

     Section 13. Notice of Change of Beneficiary. Immediately prior to any
transfer of shares of Stock to an Employee Stockholder's Trust, the Employee
Stockholder shall provide WMC and Holding with a copy of the instruments
creating the Employee Stockholder's Trust and with the identity of the
beneficiaries of the Employee Stockholder's Trust. The Employee Stockholder
shall notify WMC and Holding as soon as practicable prior to any change in the
identity of any beneficiary of the Employee Stockholder's Trust.

     Section 14. Recapitalizations, etc. The provisions of this Agreement shall
apply, to the full extent set forth herein with respect to Stock or the Options,
to any and all shares of capital shares of WMC and Holding or any capital stock,
partnership units or any other security evidencing
<PAGE>

                                                                              15

ownership interests in any successor or assign of WMC and Holding (whether by
merger, consolidation, sale of assets or otherwise) which may be issued in
respect of, in exchange for, or substitution of Stock or Options, by reason of
any share dividend, split, reverse split, combination, recapitalization,
liquidation, reclassification, merger, consolidation or otherwise.

     Section 15. State Securities Laws. WMC and Holding hereby agree to use
their best efforts to comply with all state securities or "blue sky" laws which
might be applicable to the sale of Stock and the issuance of the Options to the
Employee Stockholder.

     Section 16. Binding Effect. The provisions of this Agreement shall be
binding upon and accrue to the benefit of the parties hereto and their
respective heirs, legal representatives, successors and assigns. In the case of
a transferee permitted under Section 3(a) hereof, such transferee shall be
deemed the Employee Stockholder hereunder; provided, however, that no transferee
(including without limitation, transferees referred to in Section 3(a) hereof)
shall derive any rights under this Agreement unless and until such transferee
has delivered to WMC and Holding a valid undertaking and becomes bound by the
terms of this Agreement.

     Section 17. Amendment. This Agreement may be amended only by a written
instrument signed by the Parties hereto. Notwithstanding the foregoing, this
Agreement may be amended without the consent of any party hereto other than WMC
to provide for any change in the corporate structure of WMC, including its
conversion to a limited liability company or a merger or other business
combination of Holding and WMC.

     Section 18. Closing. Except as otherwise provided herein, the closing of
each purchase and sale of Stock and the payment of the Purchase Price by WMC or
Holding upon exercise of a Call Right, if any, pursuant to this Agreement shall
take place at the principal office of WMC on the tenth business day following
delivery of the notice by any Party of its exercise of the right to purchase or
sell such Stock or Options hereunder, as the case may be.

     Section 19. Applicable Law. The laws of the state of Delaware shall govern
the interpretation, validity and performance of the terms of this Agreement. Any
suit, action or proceeding against the Employee Stockholder, WMC or Holding,
with respect to this Agreement, or any judgment entered by any court in respect
of any thereof, may be brought in any court of competent jurisdiction in the
State of Delaware and the Parties each hereby submit to the exclusive
jurisdiction of such courts for the purpose of any such suit, action, proceeding
or judgment. The Parties hereby irrevocably waive any objections which either of
them may now or hereafter have to the laying of the venue of any suit, action or
proceeding arising out of or relating to this Agreement brought in any court of
competent jurisdiction in the State of Delaware, and hereby further irrevocably
waive any claim that any such suit, action or proceeding brought in any such
court has been brought in any inconvenient forum. No suit, action or proceeding
against any of the Parties with respect to this Agreement may be brought in any
court, domestic or foreign, or before any similar domestic or foreign authority
other than in a court of competent jurisdiction in the State of Delaware, and
the Parties hereby irrevocably waive any right which any of them may otherwise
have had to bring such an action in any other court, domestic or foreign, or
before any
<PAGE>

                                                                              16

similar domestic or foreign authority. Each Party hereto hereby irrevocably and
unconditionally waives trial by jury in any legal action or proceeding in
relation to this Agreement and for any counterclaim therein.

     Section 20. Assignability of Certain Rights by WMC, Holding and Ripplewood.
WMC, Holding and Ripplewood shall have the right to assign any or all of their
rights or obligations to purchase Stock or Options pursuant to this Agreement;
provided, however, that such assigning party shall remain obligated to perform
its obligations notwithstanding such assignment in the event that such assignee
fails to perform the obligations so assigned to it. The rights and obligations
of WMC, Holding and Ripplewood under this Agreement shall insure to the benefit
of, and be binding upon, any of their respective successors.

     Section 21. Conflicts with Other Agreements. In the event that any
provision of this Agreement conflicts in any way with the Plan or the provisions
of any Stock Option Agreement to which the Employee Stockholder is a party or
bound, the provisions of this Agreement shall govern.

     Section 22. Miscellaneous. (a) In this Agreement all references to
"dollars" or "$" are to United States dollars.

     (b) If any provision of this Agreement shall be declared illegal, void or
unenforceable by any court of competent jurisdiction, the other provisions shall
not be affected, but shall remain in full force and effect.

     (c) WMC and Holding shall have the right to deduct from any cash payment
made under this Agreement to the Employee Stockholder any federal, state or
local income or other taxes required by law to be withheld with respect to such
payment.

     Section 23. Notices. All notices and other communications provided for
