the payment of a lump sum or contingent payment that is not either (1)
specifically attributable to a particular Fiscal Quarter or (2) specifically
allocated to the last Fiscal Quarter during the term of such Contract by the
terms of such Contract, then such lump sum or contingent payment shall be
divided evenly over the term of such Contract; PROVIDED FURTHER that Wireless
Revenue shall not include (without duplication) (i) any pass-through revenue
(i.e., revenue on which the Company earns substantially no margin) accrued by
the Company and its Subsidiaries during such Fiscal Period from the provision of
any Service that is provided to a Verizon Entity as of the date hereof and
relates to SS7 database look-ups and (ii) any amount billed by the Company
during such Fiscal Period for Services that any Verizon Entity has (x) disputed
in writing or (y) failed to pay within 90 days of such amount being due, whether
or not the Company has accrued any revenue in connection with such amounts
billed; PROVIDED STILL FURTHER that the amount set forth in the immediately
preceding proviso shall be deemed Wireless Revenue with respect to any
subsequent Fiscal Period to the extent that it is paid by the Verizon Entities
in such subsequent Fiscal Period; PROVIDED STILL FURTHER that, with respect to
any Service that is not provided to a Verizon Entity as of the date hereof,
Guarantor will consider in good faith the Company's requests to exclude from
Wireless Revenue revenues on which telecommunication service providers generally
earn substantially no margin.

          (b) Capitalized terms used herein without definition shall have the
meanings assigned to them in the Merger Agreement.

     3.   QUARTERLY STATEMENTS AND PAYMENTS.

          (a) QUARTERLY STATEMENTS. No later than 45 days after the end of each
of the first three Fiscal Quarters of each Fiscal Year during the Term (or in
the case of the Fiscal Year ending December 31, 2002, the Fiscal Quarters ending
June 30 and September 30), the Company shall deliver to Guarantor a statement
(certified as having been prepared in accordance with the terms hereof by the
Company's chief financial officer) (a "QUARTERLY STATEMENT") setting forth:

               (i) the amount of Wireless Revenue for such Fiscal Quarter;
PROVIDED that the first Quarterly Statement shall set forth the amount of
Wireless Revenue for the period beginning on the Closing Date and ending on June
30, 2002;

               (ii) the sum of (A) the aggregate amount of Wireless Revenue for
such Fiscal Quarter and all prior Fiscal Quarters during the same Fiscal Year
and (B) the quotient obtained by dividing (1) the aggregate amount of all
Quarterly Payments for all prior Fiscal

                                        3
<Page>

Quarters during the same Fiscal Year by (2) 0.825 (such amount, the "AGGREGATE
QUARTERLY WIRELESS REVENUE");

               (iii) the sum of the Quarterly Revenue Targets for such Fiscal
Quarter and all prior Fiscal Quarters during the same Fiscal Year (such sum, the
"AGGREGATE QUARTERLY REVENUE TARGET"); and

               (iv) the amount by which the Aggregate Quarterly Wireless Revenue
exceeded the Aggregate Quarterly Revenue Target (such amount, the "AGGREGATE
QUARTERLY EXCESS") or the amount by which the Aggregate Quarterly Wireless
Revenue was less than the Aggregate Quarterly Revenue Target (such amount, the
"AGGREGATE QUARTERLY SHORTFALL").

          (b) QUARTERLY PAYMENTS. If, as set forth in any Quarterly Statement,
there is an Aggregate Quarterly Shortfall, Guarantor shall pay to the Company,
no later than 20 days after Guarantor's receipt of such Quarterly Statement, an
amount in cash equal to 61.875% of the Aggregate Quarterly Shortfall (a
"QUARTERLY PAYMENT").

     4.   ANNUAL STATEMENTS AND RECONCILIATION.

          (a) ANNUAL STATEMENTS. No later than 90 days after the end of each
Fiscal Year during the Term, the Company shall deliver to Guarantor a copy of
the Company's audited financial statements for such Fiscal Year together with a
statement by the Company's independent certified accountants (an "ANNUAL
STATEMENT") setting forth:

               (i) the amount of Wireless Revenue for such Fiscal Year;

               (ii) the sum of (A) the amount of Wireless Revenue for such
Fiscal Year and (B) the quotient obtained by dividing (1) the aggregate amount
of all Quarterly Payments for such Fiscal Year by (2) 0.825 (such sum, the
"ANNUAL WIRELESS REVENUE"); and

               (iii) the amount by which the Annual Wireless Revenue exceeded
the Annual Revenue Target for such Fiscal Year (such amount, the "ANNUAL
EXCESS") or the amount by which the Annual Wireless Revenue was less than the
Annual Revenue Target for such Fiscal Year (such amount, the "ANNUAL
SHORTFALL").

          (b) LIST OF VERIZON ENTITIES. Prior to January 31 of each Fiscal Year,
beginning in 2003, Guarantor shall provide the Company with a list of the
Verizon Entities for the preceding Fiscal Year.

          (c) ANNUAL RECONCILIATION. If, as set forth in any Annual Statement,
there is an Annual Shortfall at the end of any Fiscal Year, Guarantor shall pay
to the Company, no later than 20 days after Guarantor's receipt of such Annual
Statement, an amount in cash equal to 82.5% of the Annual Shortfall, subject to
Section 9 below. If, as set forth in any Annual Statement, there is an Annual
Excess at the end of any Fiscal Year, the Company shall issue to Guarantor, no
later than 20 days after Guarantor's receipt of such Annual Statement, a
promissory note (a "RECONCILIATION NOTE") substantially in the form attached
hereto as Annex B in an original principal amount equal to the lesser of (i) the
total of all amounts paid to the Company under this Guaranty during such Fiscal
Year and (ii) 82.5% of the Annual Excess.

                                        4

     5.   TAX TREATMENT. The parties shall treat any payments made under this
Guaranty as ordinary income to the payee and as a deductible expense to the
payor and shall report, act and file in all respects and for all purposes
consistent with such treatment.

     6.   SERVICE INTERRUPTIONS; PRODUCT OFFERINGS.

          (a) If in any Fiscal Period during the Term a Verizon Entity is
entitled to a credit from the Company pursuant to a Contract for a Service as a
result of any disruption in the provision of such Service, the Quarterly Revenue
Targets for the related Fiscal Period shall be reduced by the amount of such
credit.

          (b) If in the Fiscal Years ending December 31, 2004 and 2005, the
Company (i) discontinues any Service provided to a Verizon Entity and the
Verizon Entity has not agreed in writing to the discontinuance of such Service
(or has objected in writing to the discontinuance of such Service) and (ii) does
not provide a functionally similar Service to replace the discontinued Service,
then beginning in the first Fiscal Quarter after the Service is discontinued
until the Company provides a functionally similar replacement Service, the
remaining Quarterly Revenue Targets during the Term shall be reduced in an
amount equal to three times the average monthly invoice to such Verizon Entity
for such Service during the twelve-month period ending on the date such Service
is discontinued if such date is the end of a month (and if not, at the end of
the last full month preceding the date such Service is discontinued).

     7. AUDIT RIGHTS. Upon prior written notice from Guarantor and no more than
once per Fiscal Quarter, the Company agrees to provide Guarantor and its
independent certified public accountants access during normal business hours to
the books and records of the Company and its Subsidiaries for the purpose of
determining the correctness of the determination of Wireless Revenue and the
amounts set forth on any Quarterly Statement or any Annual Statement and the
calculation of such amounts.

     8. ACCOUNTING POLICIES. During the Term, the Company shall not, and shall
not permit its Subsidiaries to, change its accounting policies with respect to
accrual and recognition of revenue from those policies of the Company that were
in effect as of September 30, 2001, except to the extent such changes are
required by GAAP. If any such changes are required by GAAP, all calculations
made pursuant to this Guaranty shall be made without regard to such changes.

     9. DISPUTES.

          (a) To the extent that Guarantor disputes the calculation of any
amount to be paid by Guarantor pursuant to Section 4(c) and such amount in
dispute exceeds $50,000, then Guarantor may defer payment of such disputed
amount and shall within thirty days after receipt of the calculations provided
by the Company (or if later, promptly after the Company has provided Guarantor
with access to its books and records) provide the Company in writing with its
calculation of the amount to be paid (or credited or refunded).

          (b) The Company and Guarantor shall endeavor in good faith to resolve
any disputed matters within 30 days after the Company's receipt of such
calculation from Guarantor. If the Company and Guarantor are unable to resolve
the disputed matters, the Company and

                                        5
<Page>

Guarantor shall select a nationally known independent accounting firm (which
firm shall not be E&Y or the then regular auditors of the Company (if different
from E&Y) or Buyer) (the "GUARANTY ARBITER") to resolve the matters in dispute
in accordance with the terms of this Guaranty. The determination of the Guaranty
Arbiter in respect of the correctness of each matter remaining in dispute shall
be conclusive and binding on the Company and Guarantor. The Company and
Guarantor shall request the Guaranty Arbiter to (i) resolve all disputed matters
within 30 days after such matters are referred to it and (ii) deliver its
written decision to the Company and Guarantor, together with a brief explanation
of its basis for the decision. The determination of the Guaranty Arbiter shall
be based solely on presentations by the Company and Guarantor and shall not be
by independent review.

          (c) The fees, costs and expenses of the Guaranty Arbiter (i) shall be
borne by Guarantor in the proportion that the aggregate dollar amount of such
items submitted to the Guaranty Arbiter that are unsuccessfully disputed by
Guarantor (as finally determined by the Guaranty Arbiter) bears to the aggregate
dollar amount of such items so submitted and (ii) shall be borne by the Company
in the proportion that the aggregate dollar amount of such items so submitted
that are successfully disputed by Guarantor (as finally determined by the
Guaranty Arbiter) bears to the aggregate dollar amount of such items so
submitted.

          (d) Any amount to be paid as a result of the Guaranty Arbiter's
decision shall be paid (with interest at the Prime Rate from the date such
payment would have been due absent such dispute until the date paid, based upon
the actual number of days elapsed and a 360-day year) no later than five
business days after the written decision of the Guaranty Arbiter is sent to both
parties.

     10. COMPARABLE PRICING AND SERVICE. During the Term, the Company shall, and
shall cause its Subsidiaries to, provide each Service to the Verizon Entities at
prices and levels of service that, in the aggregate are generally consistent
with the prices and levels of service at which the Company and its Subsidiaries
provide such Service to the ten largest customers of the Company and its
Subsidiaries (based on the amount of revenue accrued by the Company and its
Subsidiaries from such Person and its Affiliates during the last 12 full months
preceding such date) other than customers that are Affiliates of Verizon.

     11. APPLICABLE LAW. This Guaranty and the legal relations between the
parties shall be governed by, and construed and enforced in accordance with, the
laws of the State of New York applicable to contracts made and performed in such
State and without regard to conflicts of law doctrines (other than New York
General Obligations Law, Section 5-1401).

     12. COSTS OF COLLECTION. If any party hereto commences legal action to
enforce its rights hereunder, the non-prevailing party shall pay to the
prevailing party all of the costs and expenses incurred by the prevailing party
in connection with such legal action, including, without limitation, reasonable
fees and disbursements of counsel to the prevailing party.

     13.  COUNTERPARTS. This Guaranty may be executed in one or more
counterparts and by different parties in separate counterparts. All of such
counterparts shall constitute one and the same agreement (or other document) and
shall become effective (unless otherwise provided

                                        6
<Page>

therein) when one or more counterparts have been signed by each party and
delivered to the other party.

     14. NO ASSIGNMENT. Neither this Guaranty nor any rights or obligations
under it are assignable or delegable by the Company except that the Company may
assign its express rights hereunder to (i) any wholly-owned subsidiary of Buyer
and (ii) any lenders of Company (as successor to Merger Sub) providing financing
for the transactions contemplated by the Merger Agreement (and all extensions,
renewals, replacements, refinancings and refundings thereof in whole or in part)
as collateral security for such financing.

     15. AMENDMENTS; WAIVERS. This Guaranty (including the Annexes hereto) may
be amended only by agreement in writing of all parties. The parties hereto agree
that this Guaranty (including the Annexes hereto) also shall not be amended in a
manner adverse to Lehman Commercial Paper Inc., as administrative agent for the
Company's senior secured credit facility, without such entity's written consent,
such consent not to be unreasonably withheld. No waiver of any provision nor
consent to any exception to the terms of this Guaranty shall be effective unless
in writing and signed by the party to be bound and then only to the specific
purpose, extent and instance so provided.

     16. NO WAIVER OF RIGHTS. No failure on the part of any party to exercise or
delay in exercising any right hereunder shall be deemed a waiver thereof, nor
shall any single or partial exercise preclude any further or other exercise of
such or any other right.

     17.  HEADINGS. The descriptive headings of the Sections and subsections of
this Guaranty are for convenience only and do not constitute a part of this
Guaranty.

     18. SEVERABILITY. If any provision of this Guaranty is determined to be
invalid, illegal or unenforceable by any Governmental Entity, the remaining
provisions of this Guaranty to the extent permitted by Law shall remain in full
force and effect provided that the essential terms and conditions of this
Guaranty for both parties remain valid, binding and enforceable and provided
that the economic and legal substance of the transactions contemplated is not
affected in any manner materially adverse to any party. In the event of any such
determination, the parties agree to negotiate in good faith to modify this
Guaranty to fulfill as closely as possible the original intents and purposes
hereof. To the extent permitted by Law, the parties hereby to the same extent
waive any provision of Law that renders any provision hereof prohibited or
unenforceable in any respect.

     19. NOTICES. Any notice or other communication hereunder must be given in
writing and (a) delivered in person, (b) transmitted by telex, telefax or
telecommunications mechanism, provided that any notice so given is also mailed

                           SENIOR MANAGEMENT AGREEMENT

         THIS SENIOR MANAGEMENT AGREEMENT (this "AGREEMENT") is made as of
February 14, 2002, by and among TSI Telecommunication Holdings, LLC, a Delaware
limited liability company (the "COMPANY"), TSI Merger Sub, Inc., a Delaware
corporation ("EMPLOYER"), and G. Edward Evans ("EXECUTIVE").

         The Company and Executive desire to enter into an agreement pursuant to
which Executive will purchase from the Company, and the Company will sell, at
least 1,979.35 of the Company's Class B Preferred Units (the "CLASS B
PREFERRED") and at least 6,475,887.65 of the Company's Common Units (the "COMMON
UNITS"). All Class B Preferred and Common Units acquired by Executive are
referred to herein as "EXECUTIVE SECURITIES" (as further defined in SECTION 9
hereof). Certain definitions are set forth in SECTION 9 of this Agreement.

         The execution and delivery of this Agreement by the Company, Employer
and Executive is a condition to the purchase of Class B Preferred and Common
Units by GTCR Fund VII, L.P., a Delaware limited partnership ("GTCR FUND VII"),
GTCR Fund VII/A, L.P., a Delaware limited partnership ("GTCR FUND VII/A"), GTCR
Co-Invest, L.P., a Delaware limited partnership ("GTCR CO-INVEST", together with
GTCR Fund VII, GTCR Fund VII/A and any other investment fund managed by GTCR
Golder Rauner, L.L.C., each an "INVESTOR" and collectively, the "INVESTORS")
pursuant to a unit purchase agreement between the Company and the Investors
dated as of the date hereof (the "PURCHASE AGREEMENT"). Certain provisions of
this Agreement are intended for the benefit of, and will be enforceable by, the
Investors.

         Employer desires to employ Executive on the terms and conditions set
forth herein, and Executive is willing to accept such employment on such terms
and conditions.

         NOW, THEREFORE, in consideration of the mutual covenants contained
herein and other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the parties to this Agreement hereby agree as
follows:

                   PROVISIONS RELATING TO EXECUTIVE SECURITIES

         1.  PURCHASE AND SALE OF EXECUTIVE SECURITIES.

         (a) Upon execution of this Agreement, Executive will purchase, and the
Company will sell, 6,475,887.65 Common Units at a price of $0.0333 per unit and
1,979.35 units of Class B Preferred at a price of $1,000.00 per unit. The
Company will deliver to Executive copies of the certificates representing such
Executive Securities, and Executive will deliver to the Company a cashier's or
certified check or wire transfer of immediately available funds in an aggregate
amount of $2,195,000.00 as payment for such Class B Preferred and Common Units.

                                       -1-
<Page>

         (b) Upon the purchase from time to time by the Investors of Securities
(as defined in the Purchase Agreement) of the Company pursuant to SECTION 1B(ii)
of the Purchase Agreement, Executive will purchase, and the Company will sell,
(i) units of Class B Preferred, (ii) Common Units or (iii) any combination of
such Securities at the same prices and in the same proportions as the Investors
purchase (each such purchase, a "SUBSEQUENT CLOSING"). The amount to be invested
by Executive at any Subsequent Closing shall equal (i) the result of the amount
being invested by the Investors in connection with such Subsequent Closing
DIVIDED BY $244,687,059 MULTIPLIED BY (ii) $2,196,078.43. The Company will
deliver to Executive copies of the certificates representing such Executive
Securities, and Executive will deliver to the Company a cashier's or certified
check or wire transfer of funds in an the aggregate amount equal to the price
per unit of such Class B Preferred or Common Unit MULTIPLIED BY the number of
such units so purchased by Executive.

         (c) 5,855,855.86 of the Common Units acquired pursuant to SECTION 1(a)
hereof are referred to herein as the "CARRIED COMMON." The remaining Common
Units that are acquired pursuant to SECTIONS 1(a) and 1(b) above are referred to
herein as the "CO-INVEST COMMON." All Class B Preferred and the Co-Invest Common
acquired by Executive hereunder are referred to herein as the "CO-INVEST UNITS."

         (d) Within 30 days after the purchase of any Carried Common hereunder,
Executive will make an effective election with the Internal Revenue Service
under Section 83(b) of the Internal Revenue Code and the regulations promulgated
thereunder in the form of EXHIBIT A attached hereto.

         (e) Until the occurrence of a Sale of the Company, any certificates
evidencing Executive Securities shall be held by the Company (i) for the benefit
of GTCR Fund VII until all amounts due under the Executive Note have been paid
in full and (ii) thereafter, for the benefit of Executive and the other
holder(s) of Executive Securities. Upon the occurrence of a Sale of the Company,
the Company will return any such certificates for the Executive Securities to
the record holders thereof. Upon the occurrence of a Public Offering, the
Company will return to the record holders thereof any certificates representing
the Co-Invest Units and the Carried Common that are Vested Units.

         (f) In connection with the purchase and sale of the Executive
Securities, Executive represents and warrants to the Company that:

             (i)   The Executive Securities to be acquired by Executive pursuant
    to this Agreement will be acquired for Executive's own account and not with
    a view to, or intention of, distribution thereof in violation of the
    Securities Act, or any applicable state securities laws, and the Executive
    Securities will not be disposed of in contravention of the Securities Act or
    any applicable state securities laws.

             (ii)  Executive is an executive officer of the Company, is
    sophisticated in financial matters and is able to evaluate the risks and
    benefits of the investment in the Executive Securities.

                                       -2-
<Page>

             (iii) Executive is able to bear the economic risk of his investment
    in the Executive Securities for an indefinite period of time because the
    Executive Securities have not been registered under the Securities Act and,
    therefore, cannot be sold unless subsequently registered under the
    Securities Act or an exemption from such registration is available.

             (iv)  Executive has had an opportunity to ask questions and receive
    answers concerning the terms and conditions of the offering of Executive
    Securities and has had full access to such other information concerning the
    Company as he has requested.

             (v)   This Agreement constitutes the legal, valid and binding
    obligation of Executive, enforceable in accordance with its terms, and the
    execution, delivery and performance of this Agreement by Executive does not
    and will not conflict with, violate or cause a breach of any agreement,
    contract or instrument to which Executive is a party or any judgment, order
    or decree to which Executive is subject.

             (vi)  Executive is a resident of the State of Florida.

         (g) As an inducement to the Company to issue the Executive Securities
to Executive, and as a condition thereto, Executive acknowledges and agrees that
neither the issuance of the Executive Securities to Executive nor any provision
contained herein shall entitle Executive to remain in the employment of the
Company, Employer or their respective Subsidiaries or affect the right of the
Company, Employer or their respective Subsidiaries to terminate Executive's
employment at any time for any reason.

         (h) Concurrently with the execution of this Agreement, Executive shall
execute in blank ten security transfer powers in the form of EXHIBIT B attached
hereto (the "SECURITY POWERS") with respect to the Executive Securities and
shall deliver such Security Powers to the Company. The Security Powers shall
authorize the Company to assign, transfer and deliver the Executive Securities
to GTCR Fund VII in accordance with the terms of the Pledge Agreement, or the
appropriate acquiror thereof pursuant to SECTION 3 below and SECTION 6 of the
Securityholders Agreement and under no other circumstances.

         (i) Executive is neither a party to, nor bound by, any other employment
agreement, consulting agreement, noncompete agreement, non-solicitation
agreement or confidentiality agreement.

         2.  VESTING OF EXECUTIVE SECURITIES.

         (a) The Carried Common shall be subject to vesting in the manner
specified in this SECTION 2. The Co-Invest Units acquired by Executive shall be
vested upon the purchase thereof. Except as otherwise provided in SECTION 2(b)
and (c) below, 5% of the Carried Common will become vested on each Quarter Date
such that on February 14, 2007 the Carried Common will be 100% vested, in each
case, however, if and only if as of each such Quarter Date Executive has been

                                       -3-
<Page>

continuously employed by the Company, Employer or any of their respective
Subsidiaries from the date of this Agreement through and including such Quarter
Date.

         (b) Upon the occurrence of a Public Offering, the lesser of (i) 50% of
all Carried Common that has not yet become vested at the time of such event and
(ii) 20% of the total Carried Common, shall become vested at the time of such
event, if as of the date of such event Executive is still employed by the
Company, Employer or any of their respective Subsidiaries.

         (c) Upon the occurrence of a Sale of the Company, all Carried Common
that has not yet become vested shall become vested at the time of such event, if
as of the date of such event Executive is still employed by the Company,
Employer or any of their respective Subsidiaries. Carried Common that have
become vested are referred to herein as "VESTED UNITS." All Carried Common that
has not vested are referred to herein as "UNVESTED UNITS."

         3.  REPURCHASE OPTION.

         (a) In the event Executive ceases to be employed by the Company,
Employer or their respective Subsidiaries for any reason (the "SEPARATION"), the
Executive Securities (whether held by Executive or one or more of Executive's
transferees, other than the Company and the Investors) will be subject to
repurchase, in each case by the Company and the Investors pursuant to the terms
and conditions set forth in this SECTION 3 (the "REPURCHASE OPTION"). The
Company may assign its repurchase rights set forth in this SECTION 3 to any
Person; PROVIDED that the Company may not assign to any Person its right to pay
any portion of the Repurchase Price for Executive Securities repurchased
hereunder in the form of Class A Preferred, as set forth in SECTION 3(e).

         (b) In the event of a Separation, (i) the purchase price for each
Unvested Unit of Carried Common will be Executive's Original Cost for such unit;
(ii) the purchase price for each Vested Unit and each unit of Co-Invest Common
will be the Fair Market Value for such unit as of the date of the Separation;
and (iii) the purchase price for each unit of Class B Preferred will be the
Unreturned Capital with respect to such unit plus all Class B Unpaid Yield
thereon (as such terms are defined in the Limited liability Company Agreement of
the Company).

         (c) The Board may elect to purchase all or any portion of the Unvested
Units, the Vested Units or the Co-Invest Units or by delivering written notice
(the "REPURCHASE NOTICE") to the holder or holders of the Executive Securities
within six months after the Separation. The Repurchase Notice will set forth the
number of Unvested Units, Vested Unit and Co-Invest Units to be acquired from
each holder, the aggregate consideration to be paid for such units and the time
and place for the closing of the transaction. The number of Executive Securities
to be repurchased by the Company shall first be satisfied to the extent possible
from the Executive Securities held by Executive at the time of delivery of the
Repurchase Notice. If the number of Executive Securities then held by Executive
is less than the total number of Executive Securities that the Company has
elected to purchase, the Company shall purchase the remaining Executive
Securities elected to be purchased from the other holder(s) of Executive
Securities under this Agreement, pro rata according to the number of Executive
Securities held by such other holder(s) at the time of delivery of such
Repurchase Notice (determined as nearly as practicable to the nearest unit). The
number of

                                       -4-
<Page>

Unvested Units, Vested Units and Co-Invest Units to be repurchased hereunder
will be allocated among Executive and the other holders of Executive Securities
(if any) pro rata according to the number of Executive Securities to be
purchased from such Person.

         (d) If for any reason the Company does not elect to purchase all of the
Executive Securities pursuant to the Repurchase Option, the Investors shall be
entitled to exercise the Repurchase Option for all or any portion of the
Executive Securities the Company has not elected to purchase (the "AVAILABLE
SECURITIES"). As soon as practicable after the Company has determined that there
will be Available Securities, but in any event within five months after the
Separation, the Company shall give written notice (the "OPTION NOTICE") to the
Investors setting forth the number of Available Securities and the purchase
price for the Available Securities. The Investors may elect to purchase any or
all of the Available Securities by giving written notice to the Company within
one month after the Option Notice has been given by the Company. If the
Investors elect to purchase an aggregate number greater than the number of
Available Securities, the Available Securities shall be allocated among the
Investors based upon the number of Common Units owned by each Investor. As soon
as practicable, and in any event within ten days, after the expiration of the
one-month period set forth above, the Company shall notify each holder of
Executive Securities as to the number of units being purchased from such holder
by the Investors (the "SUPPLEMENTAL REPURCHASE NOTICE"). At the time the Company
delivers the Supplemental Repurchase Notice to the holder(s) of Executive
Securities, the Company shall also deliver written notice to each Investor
setting forth the number of units such Investor is entitled to purchase, the
aggregate purchase price and the time and place of the closing of the
transaction. The number of Unvested Units, Vested Units and Co-Invest Units to
be repurchased hereunder shall be allocated among the Company and the Investors
pro rata according to the number of Executive Securities to be purchased by each
of them.

         (e) The closing of the purchase of the Executive Securities pursuant to
the Repurchase Option shall take place on the date designated by the Company in
the Repurchase Notice or Supplemental Repurchase Notice, which date shall not be
more than one month nor less than five days after the delivery of the later of
either such notice to be delivered. The Company will pay for the Executive
Securities to be purchased by it pursuant to the Repurchase Option by first
offsetting amounts outstanding under any bona fide debts owed by Executive to
the Company and will pay the remainder of the purchase price by, at its option,
(A) a check or wire transfer of funds, (B) issuing in exchange for such
securities a number of the Company's Class A Preferred (having the rights and
preferences set forth in the LLC Agreement) equal to (x) the aggregate portion
of the repurchase price for such Executive Securities determined in accordance
with this SECTION 3 paid by the issuance of Class A Preferred DIVIDED BY (y)
1,000, and for purposes of the LLC Agreement each such Class A Preferred unit
shall as of its issuance be deemed to have Capital Contributions made with
respect to such Class A Preferred unit equal to $1,000; PROVIDED that no more
than 50% of the purchase price shall be paid by issuing the Company's Class A
Preferred to Executive, or (C) any combination of (A) and (B) as the Board may
elect in its discretion. Each Investor will pay for the Executive Securities
purchased by it by a check or wire transfer of funds. The Company and the
Investors will be entitled to receive customary representations and warranties
from the sellers regarding such sale and to require that all sellers' signatures
be guaranteed.

         By way of example only for the purpose of clarifying the mechanics of
SECTION

                                       -5-
<Page>

3(e)(B), if the Company intends to repurchase Executive Securities consisting of
1,000 units of Class B Preferred and 5,000 Common Units by issuance of Class A
Preferred and the aggregate repurchase price determined in accordance with this
SECTION 3 is $1,000,166.50, then the Company would (i) pay Executive $500,083.25
by check or wire transfer of funds and (ii) issue to Executive 500.08325 units
of Class A Preferred and for purposes of the LLC Agreement each whole unit of
Class A Preferred issued to Executive would as of its issuance be deemed to have
Capital Contributions made for such Class A Preferred of $1,000 and the Capital
Contributions made for the fractional unit of Class A Preferred would be $83.25.

         (f) Notwithstanding anything to the contrary contained in this
Agreement, all repurchases of Executive Securities by the Company pursuant to
the Repurchase Option shall be subject to applicable restrictions contained in
the Delaware Limited Liability Company Act, the Delaware General Corporation Law
or such other governing corporate law, and in the Company's and its
Subsidiaries' debt and equity financing agreements. If any such restrictions
prohibit (i) the repurchase of Executive Securities hereunder that the Company
is otherwise entitled to make or (ii) dividends or other transfers of funds from
one or more Subsidiaries to the Company to enable such repurchases, then (x) the
Company may make such repurchases as soon as it is permitted to make repurchases
or receive funds from Subsidiaries under such restrictions and (y) commencing on
the date of the Repurchase Notice through the closing of the purchase of the
Executive Securities interest shall accrue on such purchase price on a daily
basis, at the rate of 10% per annum, compounded on the last day of each calendar
quarter.

         (g) Notwithstanding anything to the contrary contained in this
Agreement, if the Fair Market Value of Executive Securities is finally
determined to be an amount at least 10% greater than the per unit repurchase
price for such unit of Executive Securities in the Repurchase Notice or in the
Supplemental Repurchase Notice, each of the Company and the Investors shall have
the right to revoke its exercise of the Repurchase Option for all or any portion
of the Executive Securities elected to be repurchased by it by delivering notice
of such revocation in writing to the holders of Executive Securities during the
thirty-day period beginning on the date that the Company and/or the Investors
are given written notice that the Fair Market Value of a unit of Executive
Securities was finally determined to be an amount at least 10% greater than the
per unit repurchase price for Executive Securities set forth in the Repurchase
Notice or in the Supplemental Repurchase Notice.

         (h) Notwithstanding anything to the contrary contained in this
Agreement, in the event Executive fails to purchase any of the Executive
Securities that Executive is required to purchase pursuant to SECTION 1(b) above
(a "REPURCHASE TRIGGERING EVENT"), the Co-Invest Common (whether held by
Executive or one or more of Executive's transferees, other than the Company and
the Investors) will be subject to repurchase by the Company and the Investors
pursuant to the terms, conditions and procedures set forth in this SECTION 3
with respect to a repurchase in the event of a Separation. Notwithstanding
anything in this SECTION 3 to the contrary, upon a Repurchase Triggering Event
(even if there is also a Separation), the purchase price for each of the
Co-Invest Common will be Executive's Original Cost for such units.

         (i) The provisions of this SECTION 3 shall terminate with respect to
Vested Units and Co-Invest Units upon the first to occur of the consummation of
a Public Offering and the

                                       -6-
<Page>

consummation of a Sale of the Company.

         4.  PUT OPTION.

         (a) In the event of the death or Disability of Executive (for purposes
of this SECTION 4, a "PUT TRIGGERING EVENT"), Executive or one or more of
Executive's transferees or successors (other than the Company and the Investors)
may require the Company to repurchase a portion of the Executive Securities held
by Executive or Executive's transferees pursuant to the terms and conditions set
forth in this SECTION 4 (the "PUT OPTION") by delivering written notice (a "PUT
NOTICE") to the Company within six months after the Put Triggering Event;
PROVIDED that if the Put Option is exercised, the Company shall be required to
purchase (i) first, the Unvested Units and (ii) second, a pro rata portion
determined by Executive, not to exceed 50%, of each of the Class B Preferred and
the Common Units (other than the Unvested Units) held by the Executive and the
Executive's transferees.

         (b) In the event of a Put Triggering Event, (i) the purchase price for
each Unvested Unit of Carried Common will be Executive's Original Cost for such
unit; (ii) the purchase price for each Vested Unit and each Unit of Co-Invest
Common will be the Fair Market Value for such unit as of the date of the Put
Triggering Event; and (iii) the purchase price for each Unit of Class B
Preferred will be the Unreturned Capital with respect to such unit plus all
Class B Unpaid Yield thereon (as such terms are defined in the Limited liability
Company Agreement of the Company).

         (c) The closing of the repurchase of the Executive Securities pursuant
to the Put Option shall take place on the date designated by the Company, which
date shall not be more than one month nor less than five days after the delivery
of the Put Notice by the Executive. The Company will pay for the Executive
Securities to be purchased by it pursuant to the Put Option by first offsetting
amounts outstanding under any bona fide debts owed by Executive to the Company
and will pay the remainder of the purchase price by, at its option, (A) a check
or wire transfer of funds, (B) issuing in exchange for such securities a number
of the Company's Class A Preferred (having the rights and preferences set forth
in the LLC Agreement) equal to (x) the aggregate portion of the repurchase price
for such Executive Securities determined in accordance with this SECTION 4 to be
paid by the issuance of Class A Preferred DIVIDED BY (y) 1,000, and for purposes
of the LLC Agreement each such Class A Preferred unit shall as of its issuance
be deemed to have Capital Contributions made with respect to such Class A
Preferred unit equal to $1,000; PROVIDED that no more than 50% of the purchase
price shall be paid by issuing the Company's Class A Preferred to Executive, or
(C) any combination of (A) and (B) as the Board may elect in its discretion.

         (e) Notwithstanding anything to the contrary contained in this
Agreement, all repurchases of Executive Securities by the Company pursuant to
the Put Option shall be subject to applicable restrictions contained in the
Delaware Limited Liability Company Act, the Delaware General Corporation Law or
such other governing corporate law, and in the Company's and its Subsidiaries'
debt and equity financing agreements. If any such restrictions prohibit (i) the
repurchase of Executive Securities hereunder that the Company is otherwise
entitled or required to make or (ii) dividends or other transfers of funds from
one or more Subsidiaries to the Company to

                                       -7-
<Page>

enable such repurchases, then (x) the Company shall make such repurchases as
soon as it is permitted to make repurchases or receive funds from Subsidiaries
under such restrictions and (y) commencing on the date of the Put Notice through
the closing of the repurchase of the Executive Securities interest shall accrue
on such purchase price on a daily basis, at the rate of 10% per annum,
compounded on the last day of each calendar quarter.

         (f) The provisions of this SECTION 4 shall terminate with respect to
Vested Units and Co-Invest Units upon the first to occur of the consummation of
a Public Offering and the consummation of a Sale of the Company.

         5.  RESTRICTIONS ON TRANSFER OF EXECUTIVE SECURITIES.

         (a) TRANSFER OF EXECUTIVE SECURITIES. The holders of Executive
Securities shall not Transfer any interest in any units of Executive Securities,
except pursuant to (i) the terms of the Pledge Agreement (ii) the provisions of
SECTION 3 hereof, (iii) the provisions of SECTION 3 of the Securityholders
Agreement (a "PARTICIPATING SALE"), (iv) an Approved Sale (as defined in SECTION
6 of the Securityholders Agreement), or (v) the provisions of SECTION 5(b)
below.

         (b) CERTAIN PERMITTED TRANSFERS. The restrictions in this SECTION 5
will not apply with respect to any Transfer of Executive Securities made (i)
pursuant to applicable laws of descent and distribution or to such Person's
legal guardian in the case of any mental incapacity or among such Person's
Family Group, or (ii) of Common Units at such time as the Investors sell Common
Units in a Public Sale, but in the case of this CLAUSE (ii) only an amount of
units (the "TRANSFER AMOUNT") equal to the lesser of (A) the number of Vested
Units owned by Executive and (B) the number of Common Units owned by Executive
multiplied by a fraction (the "TRANSFER FRACTION"), the numerator of which is
the number of Common Units sold by the Investors in such Public Sale and the
denominator of which is the total number of Common Units held by the Investors
prior to the Public Sale; PROVIDED that, if at the time of a Public Sale of
units by the Investors, Executive chooses not to Transfer the Transfer Amount,
Executive shall retain the right to Transfer an amount of Common Units at a
future date equal to the lesser of (x) the number of Vested Units owned by
Executive at such future date and (y) the number of Common Units owned by
Executive at such future date multiplied by the Transfer Fraction; PROVIDED
further that the restrictions contained in this SECTION 5 will continue to be
applicable to the Executive Securities after any Transfer of the type referred
to in CLAUSE (i) above and the transferees of such Executive Securities must
agree in writing to be bound by the provisions of this Agreement. Any transferee
of Executive Securities pursuant to a Transfer in accordance with the provisions
of this SECTION 5(b)(i) is herein referred to as a "PERMITTED TRANSFEREE." Upon
the Transfer of Executive Securities pursuant to this SECTION 5(b), the
transferring holder of Executive Securities will deliver a written notice (a
"TRANSFER NOTICE") to the Company. In the case of a Transfer pursuant to CLAUSE
(i) hereof, the Transfer Notice will disclose in reasonable detail the identity
of the Permitted Transferee(s).

         (c) TERMINATION OF RESTRICTIONS. The restrictions set forth in this
SECTION 5 will continue with respect to each unit of Executive Securities until
the earlier of (i) the date on which such unit of Executive Securities has been

         6.  ADDITIONAL RESTRICTIONS ON TRANSFER OF EXECUTIVE SECURITIES.

         (a) LEGEND. The certificates representing the Executive Securities will
bear a legend in substantially the following form:

     "THE SECURITIES REPRESENTED BY THIS CERTIFICATE WERE ORIGINALLY ISSUED
     AS OF FEBRUARY 14, 2002, HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
     ACT OF 1933, AS AMENDED (THE "ACT"), AND MAY NOT BE SOLD OR
     TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT
     UNDER THE ACT OR AN EXEMPTION FROM REGISTRATION THEREUNDER. THE
     SECURITIES REPRESENTED BY THIS CERTIFICATE ARE ALSO SUBJECT TO
     ADDITIONAL RESTRICTIONS ON TRANSFER, CERTAIN REPURCHASE OPTIONS AND
     CERTAIN OTHER AGREEMENTS SET FORTH IN A SENIOR MANAGEMENT AGREEMENT
     BETWEEN THE COMPANY AND AN EXECUTIVE OF THE COMPANY DATED AS OF
     FEBRUARY 14, 2002. A COPY OF SUCH AGREEMENT MAY BE OBTAINED BY THE
     HOLDER HEREOF AT THE COMPANY'S PRINCIPAL PLACE OF BUSINESS WITHOUT
     CHARGE."

         (b) OPINION OF COUNSEL. No holder of Executive Securities may Transfer
any Executive Securities (except pursuant to an effective registration statement
under the Securities Act or a transfer to a member of the Executive's Family
Group) without first delivering to the Company a written notice describing in
reasonable detail the proposed Transfer, together with an opinion of counsel
(reasonably acceptable in form and substance to the Company) that neither
registration nor qualification under the Securities Act and applicable state
securities laws is required in connection with such transfer. In addition, if
the holder of the Executive Securities delivers to the Company an opinion of
counsel that no subsequent Transfer of such Executive Securities shall require
registration under the Securities Act, the Company shall promptly upon such
contemplated Transfer deliver new certificates for such Executive Securities
that do not bear the Securities Act portion of the legend set forth in SECTION
6(a). If the Company is not required to deliver new certificates for such
Executive Securities not bearing such legend, the holder thereof shall not
Transfer the same until the prospective transferee has confirmed to the Company
in writing its agreement to be bound by the conditions contained in this SECTION
6.

"work made for hire," Executive hereby assigns and agrees to assign to the
Company, Employer or such Subsidiary or Affiliate all right, title, and
interest, including without limitation, copyright in and to such copyrightable

limitation, assignments, consents, powers of attorney, and other instruments).

         (c) THIRD PARTY INFORMATION. Executive understands that the Company,
Employer and their respective Subsidiaries and Affiliates will receive from
third parties confidential or proprietary information ("THIRD PARTY
INFORMATION") subject to a duty on the Company's, Employer's and their
respective Subsidiaries' and Affiliates' part to maintain the confidentiality of
such information and to use it only for certain limited purposes. During the
Employment Period and thereafter, and without in any way limiting the provisions
of SECTION 8(a) above, Executive will hold Third Party Information in the
strictest confidence and will not disclose to anyone (other than personnel of
the Company, Employer or their respective Subsidiaries or Affiliates who need to

Subsidiaries or Affiliates any unpublished documents or any property belonging
to any former employer or any other Person to whom Executive has an obligation
of confidentiality unless consented to in writing by the former employer or
Person. Executive will use in the performance of his duties only information
that is (i) generally known and used by Persons with training and experience
comparable to Executive's and that is (x) common knowledge in the industry or
(y) is otherwise legally in the public domain, (ii) is otherwise provided or
developed by the Company, Employer or any of their respective Subsidiaries or
Affiliates or (iii) in the case of materials, property or information belonging

Person.

         9.  NONCOMPETITION AND NONSOLICITATION. Executive acknowledges that in
the course of his employment with Employer he will become familiar with the
Company's, Employer's and their respective Subsidiaries' trade secrets and with
other confidential information concerning the Company, Employer and such
Subsidiaries and that his services will be of special, unique and extraordinary
value to the Company and Employer and such Subsidiaries. Therefore, Executive
agrees that:

         (a) NONCOMPETITION. During the Employment Period and (i) in the event
of a termination of Executive's employment by the Board without Cause or the
Executive for Good Reason, the Severance Period or (ii) in the event of a

companies and other third parties that compete with the businesses of the
Company, Employer or their respective Subsidiaries or any business in which the
Company, Employer or any of their respective Subsidiaries has entertained
discussions or has requested and received information relating to the
acquisition of such business by the Company, Employer or their respective
Subsidiaries during the six-month period immediately prior to the Separation;
PROVIDED, however, that the Executive may own up to 5% of any class of an
issuer's publicly traded securities.

         (b) NONSOLICITATION. During the Noncompete Period, Executive shall not
directly or indirectly through another entity (i) induce or attempt to induce
any employee of the Company, Employer or their respective Subsidiaries to leave
the employ of the Company, Employer or such Subsidiary, or in any way interfere

Subsidiaries and any employee thereof, (ii) hire any person who was an employee
of the Company, Employer or any of their respective Subsidiaries within 180 days
prior to the time such employee was hired by Executive, (iii) induce or attempt
to induce any customer, supplier, licensee or other business relation of the
Company, Employer or any of their respective Subsidiaries to cease doing
business with the Company, Employer or such Subsidiary or in any way interfere
with the relationship between any such customer, supplier, licensee or business
relation and the Company and any Subsidiary or (iv) directly or indirectly
acquire or attempt to acquire an interest in any business relating to the
business of the Company, Employer or any of their respective Subsidiaries and
with which the Company, Employer and any of their respective Subsidiaries has,
within the six-month period immediately preceding a Separation, entertained
discussions or has requested and received information relating to the
acquisition of such business by the Company, Employer or any of their respective
Subsidiaries unless, after having such discussions or receiving such information
with respect to a business relating to the business of the Company, the Company,
Employer and any of their respective Subsidiaries have elected not to pursue the
acquisition of an interest in such business.

         (c) ENFORCEMENT. If, at the time of enforcement of SECTION 8 or this
SECTION 9, a court holds that the restrictions stated herein are unreasonable
under circumstances then existing, the parties hereto agree that the maximum
duration, scope or geographical area reasonable under such circumstances shall
be substituted for the stated period, scope or area and that the court shall be
allowed to revise the restrictions contained herein to cover the maximum
duration, scope and area permitted by law. Because Executive's services are
unique and because Executive has access to confidential information, the parties
hereto agree that money damages would be an inadequate remedy for any breach of
this Agreement. Therefore, in the event a breach or threatened breach of this
Agreement, the Company, Employer, their respective Subsidiaries or Affiliates or
their successors or assigns may, in addition to other rights and remedies
existing in their favor, apply to any court of competent jurisdiction for
specific performance and/or injunctive or other relief in order to enforce, or
prevent any violations of, the provisions hereof (without posting a bond or
other security).

         (d) ADDITIONAL ACKNOWLEDGMENTS. Executive acknowledges that the
provisions of this SECTION 9 are in consideration of: (i) employment with the
Employer, (ii) the issuance of the Executive Securities by the Company and (iii)
additional good and valuable consideration as set forth

                                      -13-
<Page>

in this Agreement. In addition, Executive agrees and acknowledges that the
restrictions contained in SECTION 8 and this SECTION 9 do not preclude Executive
from earning a livelihood, nor do they unreasonably impose limitations on
Executive's ability to earn a living. In addition, Executive acknowledges (i)
that the business of the Company, Employer and their respective Subsidiaries
will be international in scope and without geographical limitation, (ii)
notwithstanding the state of incorporation or principal office of the Company,
Employer or any of their respective Subsidiaries, or any of their respective
executives or employees (including the Executive), it is expected that the
Company and Employer will have business activities and have valuable business
relationships within its industry throughout the world, and (iii) as part of his
responsibilities, Executive will be traveling around the world in furtherance of
Employer's business and its relationships. Executive agrees and acknowledges
that the potential harm to the Company, Employer and their respective
Subsidiaries of the non-enforcement of SECTION 8 and this SECTION 9 outweighs
any potential harm to Executive of its enforcement by injunction or otherwise.
Executive acknowledges that he has carefully read this Agreement and has given
careful consideration to the restraints imposed upon Executive by this
Agreement, and is in full accord as to their necessity for the reasonable and
proper protection of confidential and proprietary information of the Company and
Employer now existing or to be developed in the future. Executive expressly
acknowledges and agrees that each and every restraint imposed by this Agreement
is reasonable with respect to subject matter, time period and geographical area.

party shall have specified by prior written notice to the sending party. Any

or sent or, if mailed, five days after deposit in the U.S. mail.

         12. GENERAL PROVISIONS.

         (a) TRANSFERS IN VIOLATION OF AGREEMENT. Any Transfer or attempted
Transfer of any Executive Securities in violation of any provision of this
Agreement or the Pledge Agreement shall be void, and the Company shall not
record such Transfer on its books or treat any purported transferee of such
Executive Securities as the owner of such equity for any purpose.

         (b) SEVERABILITY. Whenever possible, each provision of this Agreement
will be interpreted in such manner as to be effective and valid under applicable
law, but if any provision of this Agreement is held to be invalid, illegal or
unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability will not affect
any other provision or any other jurisdiction, but this Agreement will be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision had never been contained herein.

         (c) COMPLETE AGREEMENT. This Agreement, those documents expressly
referred to herein and other documents of even date herewith embody the complete
agreement and

                                      -20-
<Page>

understanding among the parties and supersede and preempt any prior
understandings, agreements or representations by or among the parties, written
or oral, that may have related to the subject matter hereof in any way.

         (d) COUNTERPARTS. This Agreement may be executed in separate
counterparts (including by means of facsimile), each of which is deemed to be an
original and all of which taken together constitute one and the same agreement.

         (e) SUCCESSORS AND ASSIGNS. Except as otherwise provided herein, this
Agreement shall bind and inure to the benefit of and be enforceable by
Executive, the Company, the Employer, the Investors and their respective
successors and assigns (including subsequent holders of Executive Securities);
PROVIDED that the rights and obligations of Executive under this Agreement shall
not be assignable except in connection with a permitted transfer of Executive
Securities hereunder. By virtue of the Merger (as defined in the Acquisition
Agreement) TSI Telecommunication Services Inc. ("TSI") will become the successor
to all of the rights, interests, duties and obligations of TSI Merger Sub, Inc.,
including, without limitation, those arising under this Agreement, and after the
Merger, TSI shall be deemed to be a party to this Agreement and all references
in this Agreement to "Employer" shall be deemed to be references to TSI.

         (f) CHOICE OF LAW. The limited liability company law of the State of
Delaware will govern all questions concerning the relative rights of the Company
and its securityholders. All other questions concerning the construction,
validity and interpretation of this Agreement and the exhibits hereto will be
governed by and construed in accordance with the internal laws of the State of
Delaware, without giving effect to any choice of law or conflict of law
provision or rule (whether of the State of Delaware or any other jurisdiction)
that would cause the application of the laws of any jurisdiction other than the
State of Delaware.

         (g) REMEDIES. Each of the parties to this Agreement (including the
Investors as third-party beneficiaries) will be entitled to enforce its rights
under this Agreement specifically, to recover damages and costs (including
attorney's fees) caused by any breach of any provision of this Agreement and to
exercise all other rights existing in its favor. The parties hereto agree and
acknowledge that money damages may not be an adequate remedy for any breach of
the provisions of this Agreement and that any party may in its sole discretion
apply to any court of law or equity of competent jurisdiction (without posting
any bond or deposit) for specific performance and/or other injunctive relief in
order to enforce or prevent any violations of the provisions of this Agreement.

         (h) AMENDMENT AND WAIVER. The provisions of this Agreement may be
amended and waived only with the prior written consent of the Company, Employer,
Executive and the Majority Holders (as defined in the Purchase Agreement).

         (i) INSURANCE. The Company or Employer, at its discretion, may apply
for and procure in its own name and for its own benefit life and/or disability
insurance on Executive in any amount or amounts considered available. Executive
agrees to cooperate in any medical or other examination, supply any information,
and to execute and deliver any applications or other instruments in writing as
may be reasonably necessary to obtain and constitute such insurance.

                                      -21-
<Page>

Executive hereby represents that he has no reason to believe that his life is
not insurable at rates now prevailing for healthy men of his age.

         (j) BUSINESS DAYS. If any time period for giving notice or taking
action hereunder expires on a day which is a Saturday, Sunday or holiday in the
state in which the Company's chief executive office is located, the time period
shall be automatically extended to the business day immediately following such
Saturday, Sunday or holiday.

         (k) INDEMNIFICATION AND REIMBURSEMENT OF PAYMENTS ON BEHALF OF
EXECUTIVE. The Company, Employer and their respective Subsidiaries shall be
entitled to deduct or withhold from any amounts owing from the Company or any of
its Subsidiaries to Executive any federal, state, local or foreign withholding
taxes, excise taxes, or employment taxes ("TAXES") imposed with respect to
Executive's compensation or other payments from the Company or any of its
Subsidiaries or Executive's ownership interest in the Company, including,
without limitation, wages, bonuses, dividends, the receipt or exercise of equity
options and/or the receipt or vesting of restricted equity. In the event the
Company or its Subsidiaries does not make such deductions or withholdings,
Executive shall indemnify the Company and its Subsidiaries for any amounts paid
with respect to any such Taxes, together with any interest, penalties and
related expenses thereto.

         (l) REASONABLE EXPENSES. The Company agrees to pay the reasonable fees
and expenses of Executive's counsel arising in connection with the negotiation
and execution of this Agreement and the consummation of the transactions
contemplated by this Agreement.

         (m) TERMINATION. This Agreement (except for the provisions of SECTIONS
7(a) and (b)) shall survive a Separation and shall remain in full force and
effect after such Separation.

         (n) ADJUSTMENTS OF NUMBERS. All numbers set forth herein that refer to
unit prices or amounts will be appropriately adjusted to reflect unit splits,
unit dividends, combinations of units and other recapitalizations affecting the
subject class of equity.

         (o) DEEMED TRANSFER OF EXECUTIVE SECURITIES. If the Company (and/or the
Investors and/or any other Person acquiring securities) shall make available, at
the time and place and in the amount and form provided in this Agreement, the
consideration for the Executive Securities to be repurchased in accordance with
the provisions of this Agreement, then from and after such time, the Person from
whom such units are to be repurchased shall no longer have any rights as a
holder of such units (other than the right to receive payment of such
consideration in accordance with this Agreement), and such units shall be deemed
purchased in accordance with the applicable provisions hereof and the Company
(and/or the Investors and/or any other Person acquiring securities) shall be
deemed the owner and holder of such units, whether or not the certificates
therefor have been delivered as required by this Agreement.

         (p) NO PLEDGE OR SECURITY INTEREST. The purpose of the Company's
retention of Executive's certificates and executed security powers is solely to
facilitate the repurchase provisions set forth in SECTION 3 herein and SECTION 6
of the Securityholders Agreement and does not constitute a pledge by Executive
of, or the granting of a security interest in, the underlying equity; PROVIDED
that

                                      -22-
<Page>

the Company acknowledges that until GTCR Fund VII releases the security interest
granted to it in the Executive Securities by Executive pursuant to the terms of
the Pledge Agreement the Company shall hold such certificates on behalf of GTCR
Fund VII subject to and in accordance with the terms of the Pledge Agreement.

         (q) RIGHTS GRANTED TO GTCR FUND VII AND ITS AFFILIATES. Any rights
granted to GTCR Fund VII, GTCR Fund VII/A, GTCR Co-Invest and their Affiliates
hereunder may also be exercised (in whole or in part) by their respective
designees (which designees may be Affiliates of GTCR Fund VII, GTCR Fund VII/A
and/or GTCR Co-Invest).
