        5.1    IN GENERAL. Subject to Section 9.2, any distributions of cash or

        Management Percentage Interest;

                      (vi)   sixth, to the extent of an amount equal to the
        Junior Common Redemption Value (for the avoidance of doubt, such Junior
        Common Redemption Value to have been reduced by the amount distributed
        pursuant to Section 5.2(a)(iv)) times the Class B Unit Gross Up, divided
        between the Junior Common Unitholders and the Class B Unitholders as
        follows:

                             (x) the Residual Percentage times the amount of
               such distribution, PRO RATA to the Junior Common Unitholders and

the Code for a calendar year corporation to pay quarterly installments of
estimated tax, the Company shall distribute to each holder of Preferred, Senior
Common, Junior Common, Class B or Management Units cash equal to 40% of the
amount allocable to such Unitholder under Section 6.2(a) hereof. Any
distributions under this Section 5.3 shall be treated for all purposes of this
Agreement as having been distributed with respect to the Preferred, Senior
Common, Junior Common, Class B or Management Units, as the case may be. Rights
to distributions under this Section 5.3 shall rank senior to any rights to
distributions under Sections 5.2 and 5.4.

        5.4    MANDATORY DISTRIBUTIONS ON PREFERRED UNITS. Subject to the
Financing Agreements, the Company shall make cash distributions to the Preferred
Unitholders in an amount equal to the annual Yield on the Preferred Units.

        5.5    LIMITATION ON DISTRIBUTIONS. Notwithstanding any provision in
this Agreement to the contrary, the Company, and the Board on behalf of the
Company, shall not make a distribution to any Member on account of its interest
in the Company if such distribution would violate the Act.

               (c)    MISCELLANEOUS AND REGULATORY TAX ALLOCATIONS.
Notwithstanding anything to the contrary set forth in this Agreement, the
following special allocations, if applicable, shall be made in the following
order:

                      (i)    COMPANY MINIMUM GAIN CHARGEBACK. Except as
        otherwise provided in Treasury Regulations Section 1.704-2(f),
        notwithstanding any other provision of this Article VI, if there is a
        net decrease in Company Minimum Gain during any Fiscal Year, each
        Unitholder shall be specially allocated items of Company income and gain
        for such Fiscal Year (and, if necessary, subsequent Fiscal Years) in an
        amount equal to such Unitholder's share of the net decrease in Company
        Minimum Gain, determined in accordance with Treasury Regulations Section
        1.704-2(g). Allocations pursuant to the previous sentence shall be made
        in proportion to the respective amounts required to be allocated to each
        Unitholder pursuant thereto. The items to be so allocated shall be
        determined in accordance with Treasury Regulations Sections
        1.704-2(f)(6) and 1.704-2(j)(2). This Section 6.2(c)(i) is intended to
        comply with the minimum gain chargeback requirements set forth in
        Treasury Regulations Section 1.704-2(f) and shall be interpreted
        consistently therewith.

                      (ii)   MEMBER MINIMUM GAIN CHARGEBACK. Except as otherwise
        provided in Treasury Regulations Section 1.704-2(i)(4), notwithstanding
        any other provision of this Article VI, if there is a net decrease in
        Member Minimum Gain attributable to a Member Nonrecourse Debt during any
        Fiscal Year, each Unitholder who has a share of the Member Minimum Gain
        attributable to such Member Nonrecourse Debt, determined in accordance
        with Treasury Regulations Section 1.704-2(i)(5), shall be specially
        allocated items of Company income and gain for such Fiscal Year (and, if
        necessary, subsequent Fiscal Years) in an amount equal to the portion of
        such Unitholder's share of the net decrease in Member Minimum Gain
        attributable to such Member Nonrecourse Debt, determined in accordance
        with Treasury Regulations Section 1.704-2(i)(4). Allocations pursuant to
        the previous sentence shall be made in proportion to the respective
        amounts required to be allocated to each Unitholder pursuant thereto.
        The items to be so allocated shall be determined in accordance with
        Treasury Regulations Sections 1.704-2(i)(4) and 1.704-2(j)(2). This
        Section 6.2(c)(ii) is intended to comply with Treasury Regulations
        Section 1.704-2(i)(4) and shall be interpreted consistently therewith.

                      (iii)  QUALIFIED INCOME OFFSET. In the event any
        Unitholder unexpectedly receives any adjustments, allocations or
        distributions described in subparagraphs (4), (5) or (6) of Treasury
        Regulations Section 1.704-1(b)(2)(ii)(d), such Unitholder shall be
        allocated items of Company income or gain in an amount and manner
        sufficient to eliminate such Unitholder's Adjusted Capital Account
        Deficit as quickly as possible to the extent required by the Treasury
        Regulations; PROVIDED, that an allocation pursuant to this Section
        6.2(d)(iii) shall be made only if and to the extent that such Unitholder
        would have an

                                      -22-
<Page>

        Adjusted Capital Account Deficit after tentatively making all other
        allocations provided in this Article VI as if this Section 6.2(c)(iii)
        were not in this Agreement.

                      (iv)   NONRECOURSE DEDUCTIONS. Nonrecourse Deductions for
        any Fiscal Year shall be specially allocated PRO RATA 73.5% to the
        Senior Common Unitholders and 26.5% to the Junior Common Unitholders.
        Any Member Nonrecourse Deduction for any Fiscal Year shall be specially
        allocated to the Unitholder who bears the economic risk of loss with
        respect to the Member Nonrecourse Debt to which such Member Nonrecourse
        Deductions are attributable in accordance with Treasury Regulations
        Section 1.704-2(i)(1).

                      (v)    ADJUSTMENTS OCCASIONED BY CODE SECTION 754
        ELECTION. To the extent an adjustment to the adjusted tax basis of any
        Company asset pursuant to Code Section 734(b) or Code Section 743(b) is
        required pursuant to an election under Code Section 754 to be taken into
        account in determining Capital Accounts as the result of a distribution
        to a Unitholder in complete liquidation of its interest, the amount of
        such adjustment to Capital Accounts shall be treated as an item of gain
        (if the adjustment increases the basis of the asset) or loss (if the
        adjustment decreases such basis) and such gain or loss shall be
        specially allocated to the Unitholders in accordance with their
        interests in the event Treasury Regulations Section
        1.704-1(b)(2)(iv)(m)(2) applies, or to the Member to whom such
        distribution was made in the event Treasury Regulations Section
        1.704-1(b)(2)(iv)(m)(4) applies.

                      (vi)   TREATMENT OF REGULATORY ALLOCATIONS. The
        allocations set forth in this Section 6.2(c) (the "REGULATORY
        ALLOCATIONS") are intended to comply with and shall be interpreted
        consistently with certain requirements of Treasury Regulations Sections
        1.704-1 and 1.704-2. Notwithstanding any other provisions of this
        Article VI (other than the Regulatory Allocations), the Regulatory
        Allocations shall be taken into account in allocating other Net Profits
        and Net Losses and items of income, gain, loss and deduction among
        Unitholders so that, to the extent possible, the net amount of such
        allocations of other Net Profits and Net Losses and other items and the
        Regulatory Allocations to each Unitholder shall be equal to the net
        amount that would have been allocated to such Unitholder if the
        Regulatory Allocations had not occurred.

               (d)    LOSS LIMITATION. Net Loss allocated pursuant to Section
6.2(b) shall not exceed the maximum amount of Net Loss that can be allocated
without causing any Unitholder to have an Excess Loss. For this purpose, "EXCESS
LOSS" means any Net Loss the allocation of which to a Unitholder would cause
such Unitholder to have an Adjusted Capital Account Deficit (or increase the
amount of such deficit) at the end of any Fiscal Year. If some but not all
Unitholders would be allocated an Excess Loss as a consequence of an allocation
of Net Loss pursuant to Section 6.2(b), the foregoing limitation shall be
applied on a Unitholder by Unitholder basis so as to allocate the maximum
permissible Net Loss to each Unitholder under Treasury Regulations Section
1.704-1(b)(2)(ii)(d). Any Net Loss in excess of the limitation contained in this
Section 6.2(d) shall be allocated PRO RATA 26.5% to the Junior Common
Unitholders and 73.5% to the Senior Common Unitholders. Prior to any allocation
of Net Profit under Section 6.2(a), after an Excess Loss has been allocated to
one or more Unitholders, an equal amount of

                                      -23-
<Page>

Net Profit shall be allocated to such Unitholders in proportion to and to the
extent of the Excess Losses previously allocated to them.

               (e)    CLASS B UNIT LIMITATION. Anything in this Agreement to the
contrary notwithstanding, no allocation of any item of income, gain, loss,
deduction or credit shall be made to the Class B Unitholders in excess of the
amount described in Treasury Regulation Section 1.752-2(d)(1).

               (f)    Special Allocation and Distribution to Senior Common
Unitholders. Anything in this Agreement to the contrary notwithstanding, upon
the occurrence of a Change of Control specified in Section 8.6(b)(ii) hereof,
(i) to the extent an amount of Net Profit is available after allocations
pursuant to Section 6.2(a)(i) and (ii) have been made in full (such amount, the
"Residual Profit"), the amount of Net Profit allocated to the Senior Common
Unitholders pursuant to Section 6.2(a)(iii) shall be increased by the lesser of
(x) $1,500,000 and (y) the Residual Profit (such increase, the "Special
Allocation"); and (ii) subject to Sections 5.3, 5.4, 5.5, 7.10 and 9.2 hereof
and to the extent a sufficient amount of cash is available after distributions
pursuant to Section 5.2(a)(i) have been made in full, the amount distributed to
Senior Common Unitholders pursuant to Section 5.2(a)(ii) shall be increased by
the amount of the Special Allocation.

        6.3    ALLOCATIONS FOR TAX PURPOSES.

               (a)    In accordance with Section 704(c) of the Code and the
Treasury Regulations thereunder, income, gain, loss, and deduction with respect
to any property contributed to the capital of the Company shall, solely for tax
purposes, be allocated among the Unitholders so as to take account of any
variation between the adjusted basis of such property to the Company for Federal
income tax purposes and its initial Gross Asset Value using the traditional
method described in Treasury Regulations Section 1.704-3(b) (without curative or
remedial allocations).

               (b)    In the event the Gross Asset Value of any Company asset is
adjusted pursuant to subparagraph (b) of the definition of Gross Asset Value,
subsequent allocations of income, gain, loss, and deduction with respect to such
asset shall take account of any variation between the adjusted basis of such
asset for Federal income tax purposes and its Gross Asset Value in the same
manner as under Section 704(c) of the Code and the Treasury Regulations
thereunder.

               (c)    Subject to the preceding paragraphs (a) and (b), for
United States Federal, state and local income tax purposes, the income, gains,
losses and deductions of the Company shall, for each taxable period, be
allocated among the Unitholders in the same manner and in the same proportion
that such items have been allocated among the Unitholders' respective Capital
Accounts.

        6.4    DISTRIBUTION IN KIND. If any property is distributed in kind to
the Unitholders, it shall first be written up or down to its Fair Market Value
as of the date of such distribution), thus creating book gain or loss for the
Company, and the Fair Market Value of the property received by each Unitholder
as so determined shall be debited against such Unitholder's Capital Account at
the time of distribution.

                                      -24-

        6.5    DEBT ALLOCATIONS. Solely for purposes of determining a
Unitholder's proportionate share of the "excess nonrecourse liabilities" of the
Company within the meaning of Treasury Regulations Section 1.752-3(a)(3), the
Unitholders' interests in Company profits with respect to the Financing
Agreements will be in proportion to the Net Profit allocations under Section
6.2(a)(ii) with respect to the Preferred Units.

                                   ARTICLE VII

expressly provided for herein, the Members hereby consent to the exercise by the
Board of all such powers and rights conferred on them by the Act or otherwise by
law with respect to the management and control of the Company. No Member and no
Representative, in its capacity as such, shall have any power to act for, sign
for, or do any act that would bind the Company. The Board shall devote such time
and effort to the affairs of the Company as they may deem appropriate for the
oversight of the management and affairs of the Company. Each Member acknowledges
and agrees that no Member shall, in its capacity as a Member, be bound to devote
all of such Member's business time to the affairs of the Company, and that each
Member and such Member's Affiliates do and will continue to engage for such
Member's own account and for the account of others in other business ventures.
To the fullest extent permitted by Applicable Law, each Representative shall
have such rights and duties as are applicable to directors of a Corporation.

               (b)    DELEGATION BY BOARD. The Board shall have the power and
authority to delegate to one or more other Persons the Board's rights and powers
to manage and control the business and affairs of the Company, including
delegating such rights and powers of the Board to agents and employees of the
Company (including Officers). The Board may authorize any Person (including,
without limitation, any Member, Officer or Representative) to enter into any
document on behalf of the Company and perform the obligations of the Company
thereunder. Notwithstanding the foregoing, the Board shall not have the power
and authority to delegate any rights or powers customarily requiring the
approval of the directors of a Corporation and no Officer or other Person shall
be authorized or empowered to act on behalf of the Company in any way beyond the
customary rights and powers of an officer of a Corporation.

power and authority as if such individual were a Raytheon Representative.

such resignation shall take effect at the time the Board receives such notice or

choose not to fill any office for any period as it may deem advisable. Officers
need not be residents of the State of Delaware or Members. Any Officers so
designated shall have such authority and perform such duties as the Board may,
from time to time, delegate to them. The Board may assign titles to particular
Officers. Each Officer shall hold office until his successor shall be duly
designated and shall have qualified as an Officer or until his death or until he
shall resign or shall have been removed in the manner hereinafter provided. The

in such resignation. Any Officer may be removed as such, either with or without
cause, at any time by the Board. Designation of any Person as an Officer by the
Board pursuant to the provisions of Section 7.9(a) shall not in and of itself
vest in such Person any contractual or employment rights with respect to the
Company.

        within 120 days after the end of each Fiscal Year of the Company, a
        consolidated Balance Sheet as of the end of such fiscal year, a
        consolidated Statement of Income and a consolidated Statement of Cash
        Flows of the Company and its subsidiaries for such year, setting forth

all or substantially all of the assets of the Company in accordance with the
provisions of this Agreement.

               (b)    CHANGE IN LAW. In the event that a change in law could
result in taxation of the Company as a C Corporation, the Raytheon Member and
the RAH Member shall cooperate in good faith to restructure the Company to avoid

               (c)    SECTION 754 ELECTION. The Company shall make an election
under Section 754 of the Code in connection with any Transfer of Units permitted

                                  ARTICLE VIII

                               TRANSFERS OF UNITS

        8.1    GENERAL.

               (a)    RESTRICTIONS ON TRANSFER. No Unitholder shall Transfer any
Units other than in accordance with the terms and conditions of this Article
VIII and the other provisions of

                                      -31-
<Page>

this Agreement. Other than to a Permitted Transferee, the Common Units may not
be Transferred at any time prior to the 3rd anniversary of the date hereof. A
Management Unitholder may not Transfer any Units at any time except as otherwise
specifically permitted in this Article VIII. Notwithstanding anything to the
contrary contained herein, no Unitholder shall Transfer any Units if such
Transfer or creation would cause (i) the Company to be taxed as a C Corporation,
(ii) a termination of the Company for purposes of Section 708 of the Code (a
"708 TERMINATION"), unless the Transferring Unitholder indemnifies and
reimburses the Other Unitholders for any taxes (including interest and
penalties) incurred by the Other Unitholders that would not have been incurred
but for such 708 Termination, (iii) the Company to be treated as a
publicly-traded partnership for purposes of Section 7704 of the Code, or (iv)
any transferee to become a person described in Treasury Regulation Section
1.752-2(c) (other than a person described in Treasury Regulation Section
1.752-2(d)) unless, in the case of each of clauses (i), (ii), (iii) and (iv),
such Transfer or creation (A) is pursuant to an Initial Public Offering, or (B)
receives the express prior written approval of the Raytheon Representatives.

               (b)    VOID TRANSFERS. Any Transfer or attempted Transfer of any
Units in violation of any provision of this Agreement shall be null and void,
and the Company shall not record such Transfer on its books or, to the fullest
extent permitted by law, treat any purported Transferee of such Units as the
owner thereof for any purpose.

               (c)    TRANSFER MECHANICS. In connection with any proposed
Transfer of Units, the holder of the Units proposed to be Transferred shall
deliver to the Company at least twenty (20) days (and no more than sixty (60)
days) prior to any such Transfer an opinion of counsel reasonably acceptable to
the Company to the effect that such proposed Transfer may be effected in
compliance with the Securities Act; PROVIDED, that any such proposed Transfer
permitted under Section 8.2(c) shall not require an opinion of counsel, but must
otherwise be consummated in compliance with the Securities Act. In addition, if
the holder of the Units proposed to be Transferred delivers to the Company an
opinion of counsel reasonably acceptable to the Company to the effect that no
subsequent Transfer of such Units shall require registration under the
Securities Act, the Company shall promptly upon consummation of such Transfer
deliver to such holder new certificates for such Units that do not bear the
legend set forth in Section 8.4. If the Company is not required to deliver new
certificates for such Units (if certificates were previously issued for such
Units) not bearing such legend, the holder thereof shall not consummate a
Transfer of the same until the prospective Transferee has confirmed to the
Company in writing its agreement to be bound by the conditions contained herein.

               (d)    SPECIAL DELIVERIES. At least fourteen (14) days (and no
more than sixty (60) days) prior to the intended date of any proposed Transfer
by the RAH Member, the RAH Member shall deliver a Transfer Notice to the
Company, and the Company shall within two business days forward such Transfer
Notice to the Raytheon Member and such other information as is reasonably
required for the Raytheon Member to evaluate the consequences of the proposed
Transfer under Code Sections 708 and 7704. The Company shall also, promptly
following receipt of notice of the consummation of such Transfer, give written
notice to the Raytheon Member setting forth the number of Units so Transferred,
and the identity of such Transferees.

               (e)    REMOVAL OF LEGEND. Upon the request of any Unitholder, the
Company shall remove the legend set forth in Section 8.3 below from the
certificates for such Unitholder's

                                      -32-
<Page>

Units; PROVIDED, that such Units are eligible for sale pursuant to Rule 144(k)
under the Securities Act (or any similar rule or rules then in effect) and such
Unitholder delivers to the Company an opinion of counsel reasonably acceptable
to the Company to the effect that such Units are so eligible.

               (f)    SURVIVAL OF RESTRICTIONS. Until the Initial Public
Offering, all Transferees of Units under this Article VIII who are not parties
to this Agreement shall have agreed in writing to be bound by the provisions of
this Agreement by executing a joinder substantially in the form attached hereto
as EXHIBIT A and, other than Permitted Transferees, each such Transferee shall
be deemed to be a Unitholder only until such Transferee has been admitted as a
Member pursuant to the provisions of Section 3.2(b).

        8.2    TAG-ALONG RIGHTS; DRAG-ALONG; FIRST OFFER RIGHTS; PERMITTED
TRANSFERS.

               (a)    TAG-ALONG RIGHTS.

                      (i)    Subject to Section 8.2(c) and other than in
        connection with a Permitted Transfer, an underwritten public offering or
        Rule 144 under the Securities Act, in the event that the RAH Member
        proposes to Transfer Common Units in any control transaction however
        structured, the RAH Member shall deliver a Transfer Notice to the
        Raytheon Member and the Class B Unitholders at least 30 days prior to
        any such Transfer. The Raytheon Member and the Class B Unitholders may
        elect to participate in the contemplated Transfer by delivering written
        notice to the RAH Member within 15 days after delivery by the RAH Member
        of such Transfer Notice. If the Raytheon Member and the Class B
        Unitholders elect to participate in such Transfer, the Raytheon Member
        and the Class B Unitholders shall each be entitled to Transfer in the
        contemplated Transfer, on the same contract terms (including without
        limitation, making the same representations, warranties, covenants,
        indemnities and agreements as the RAH Member), the number of Common
        Units or Class B Units, as the case may be, such that the proportion of
        Common Units, or Class B Units, as the case may be, so transferred to
        the such Member's total number of Common Units or Class B Units, as the
        case may be, is equal to the proportion of the RAH Member's Common Units
        being transferred to the RAH Member's total Units, at the price
        determined under (ii) below. Notwithstanding anything to the contrary
        herein, in any Transfer to which this Section applies the Company, at
        the election of the Raytheon Member, shall, or shall cause the
        prospective transferee to redeem all of the Preferred Units in cash by
        wire transfer of immediately available funds at a redemption price equal
        to the Preferred Redemption Value for such Units, such redemption to
        occur at or before the time the RAH Member receives proceeds from the
        sale of Units.

                      (ii)   In furtherance of Section 8.2(a)(i), it is the
        intent of the parties that, in a transaction in which tag-along rights
        apply, the aggregate sale proceeds shall be divided proportionately with
        respect to the Raytheon Member, the Class B Unitholders and the RAH
        Member based on the shares of the liquidation proceeds that the Raytheon
        Member, the Class B Unitholders and the RAH Member would receive,
        respectively, in the event of a hypothetical liquidation of the Company
        at the enterprise value implied by the proposed sales price; and
        appropriate adjustments will be made to take account of

                                      -33-
<Page>

        whether Preferred Units participate in such tag-along, however in any
        event the Preferred Units shall receive the Preferred Redemption Value
        for such Units.

               (b)    DRAG ALONG. (i) At any time from and after the 3rd
anniversary from the date hereof, all Unitholders hereby agree, if requested by
the RAH Member pursuant to a Transfer Notice to the Unitholders at least 30 days
prior to any such Transfer, to sell the Drag Along Sale Amount of the Units then
held by the Unitholders to the purchaser specified in such Transfer Notice, in
the manner and on the same contract terms set forth in this Transfer Notice
(including without limitation, making the same representations, warranties,
covenants, indemnities, and agreements as the RAH Members), to a bona fide
prospective purchaser that is not an Affiliate of the RAH Member, provided that
in any such sale the RAH Member must sell all Units then held by the RAH Member.
Notwithstanding anything to the contrary herein, in any Transfer to which this
Section applies the Company shall, or shall cause the prospective transferee to
redeem all of the Preferred Units in cash by wire transfer of immediately
available funds at a redemption price equal to the Preferred Redemption Value
for such Units, such redemption to occur at or before the time the RAH Member
receives proceeds from the sale of Units. The "DRAG ALONG SALE AMOUNT", shall
equal the number of Units required by the purchaser to be included in such sale
less any Units being sold by the RAH Member.

                      (ii)   In furtherance of Section 8.2(b)(i), it is the
intent of the parties that, in a transaction in which drag-along rights apply,
the aggregate sale proceeds shall be divided proportionately with respect to the
Unitholders based on the Unitholders' respective shares of the liquidation
proceeds that Unitholders would receive, respectively, in the event of a
hypothetical liquidation of the Company at the enterprise value implied by the
proposed sales price; and appropriate adjustments will be made to take account
of the participation of the Preferred Units, however in any event the Preferred
Units shall receive the Preferred Redemption Value for such Units.

               (c)    FIRST OFFER RIGHTS. Other than a Transfer made pursuant to
Section 8.2(d), prior to any Transfer of Units by the Raytheon Member (the
"Selling Unitholder"), the Selling Unitholder shall deliver a written notice to
the Company and the RAH Member, such written notice to specify in reasonable
detail the number and class of Units to be so Transferred, the proposed purchase
price therefor and the other terms and conditions of such proposed Transfer (a
"FIRST OFFER NOTICE"). The RAH Member may elect to purchase all (but not less
than all) of the Units to be Transferred, upon the terms and conditions as those
set forth in the First Offer Notice and other reasonable and customary terms and
conditions, by delivering a written notice of such election to the Selling
Unitholder within 15 days after the First Offer Notice has been delivered to the
RAH Member. If the RAH Member does not elect to purchase all of the Units
specified in the First Offer Notice, then the Selling Unitholder may Transfer to
any Person the Units contemplated to be Transferred at a price and on terms and
conditions in the aggregate no more favorable to the Transferee than those
specified in the First Offer Notice during the 180-day period immediately
following the date on which the First Offer Notice has been delivered to the RAH
Member. Any Units not Transferred within such 180-day period will be subject to
the provisions of this Section 8.2(c) upon subsequent Transfer. The Company and
the RAH Member agree that the Raytheon Member will have full rights to
participate in any process which could result in the sale, merger, liquidation,
combination, sale of all or substantially all of the assets, or similar
transaction, involving the Company and/or its assets.

        (d)    PERMITTED TRANSFERS ETC.

               (i)    PERMITTED TRANSFEREES. Subject to Section 8.1, the
restrictions on Transfer contained in Sections 8.2(a) and (b) shall not apply
with respect to any Transfer (A) in the case of a Member which is a natural
Person, of Units pursuant to Applicable Laws of descent and distribution or to
any member of such Member's Family Group, (B) in the case of the RAH Member,
among its Affiliates and to individuals providing services on a full-time basis
to the Company or any of its Subsidiaries, and (C) in the case of the Raytheon
Member, among its wholly owned Subsidiaries (each a "PERMITTED TRANSFEREE").

               (ii)   ISSUANCES TO MANAGEMENT UNITHOLDERS. Subject to Section
8.1, it is hereby acknowledged and agreed that the Company may issue new Units
to individuals who are providing services on a full-time basis to the Company or
any of its Subsidiaries. Such persons shall thereupon become Management
Unitholders for purposes of this Agreement. In no event shall the aggregate
Management Percentage Interests of the Management Unitholders exceed 7.5%.

               (iii)  ISSUANCES TO CLASS B UNITHOLDERS. Subject to Section 8.1,
upon the execution and delivery of the Senior Unsecured Debt Documents and
receipt by the Company of the consideration for the notes issued by the Company
thereunder, each Class B Unitholder shall receive and shall be deemed to own the
number of Class B Units set forth opposite such Member's name on Schedule A.
Notwithstanding the preceding, it is hereby acknowledged and agreed that the
Company may issue Class B Units solely to persons pursuant to and in connection
with the Financing Agreements, PROVIDED, HOWEVER, no Class B Units may be issued
to any person if, as a result of such issuance, such person would become a
person described in Treasury Regulation Section 1.752-2(c) (other than a person
described in Treasury Regulation Section 1.752-2(d)). Upon an issuance of Class
B Units to a person that is permissible hereunder, such persons shall become
Class B Unitholders for purposes of this Agreement. In no event shall the Class
B Unit Percentage exceed 8%.

        8.3    LEGEND. The Units have not been registered under the Securities
Act and, therefore, in addition to the other restrictions on Transfer contained
in this Agreement, cannot be sold unless subsequently registered under the
Securities Act or an exemption from such registration is then available. To the
extent such Units have been certificated, each certificate evidencing Units and
each certificate issued in exchange for or upon the Transfer of any Units shall
be stamped or otherwise imprinted with a legend in substantially the following
form:

               "THE SECURITIES REPRESENTED BY THIS CERTIFICATE WERE
               ORIGINALLY ISSUED ON JUNE 27, 2001 AND HAVE NOT BEEN
               REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED
               (THE "ACT"), AND THE ISSUER (THE "COMPANY") HAS NOT
               BEEN REGISTERED UNDER THE U.S. INVESTMENT COMPANY ACT
               OF 1940, AS AMENDED

                                      -35-
<Page>

               (THE "INVESTMENT COMPANY ACT"). THE SECURITIES
               REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD OR
               TRANSFERRED (X) IN THE ABSENCE OF AN EFFECTIVE
               REGISTRATION STATEMENT UNDER THE ACT OR IN THE ABSENCE
               OF AN EXEMPTION FROM REGISTRATION THEREUNDER, OR (Y) IF
               SUCH SALE OR TRANSFER CANNOT BE EFFECTED WITHOUT THE
               LOSS BY THE COMPANY OF ANY APPLICABLE INVESTMENT
               COMPANY ACT EXEMPTION. THE SECURITIES REPRESENTED BY
               THIS CERTIFICATE ARE ALSO SUBJECT TO ADDITIONAL
               RESTRICTIONS ON TRANSFER SPECIFIED IN THE AMENDED AND
               RESTATED LIMITED LIABILITY COMPANY AGREEMENT, DATED AS
               OF JUNE 27, 2001, AS AMENDED AND MODIFIED FROM TIME TO
               TIME. THE COMPANY RESERVES THE RIGHT TO REFUSE THE
               TRANSFER OF SUCH SECURITIES UNTIL SUCH CONDITIONS HAVE
               BEEN FULFILLED WITH RESPECT TO SUCH TRANSFER. A COPY OF
               SUCH CONDITIONS SHALL BE FURNISHED BY THE COMPANY TO
               THE HOLDER HEREOF UPON WRITTEN REQUEST AND WITHOUT
               CHARGE."

The Company shall imprint such legend on certificates (if any) evidencing Units.
The legend set forth above shall be removed from the certificates (if any)
evidencing any Units which cease to be Units in accordance with the definition
thereof. Notwithstanding the foregoing, to the extent the Units are not
certificated, this Agreement will contain a legend in substantially the form
stated above.

        8.4    INITIAL PUBLIC OFFERING. Immediately prior to the consummation of
an Initial Public Offering, the Members and Board will take all necessary and
desirable actions in consummation of any such Initial Public Offering, and vote
for a recapitalization of the Company into a corporation and/or exchange of the
Units into securities (the "RECLASSIFIED SECURITIES") the Board finds
acceptable; PROVIDED, that (i) the Reclassified Securities provide each
Unitholder with the same or better, economic interest, governance, priority and
other rights and privileges as such Unitholder had prior to such
recapitalization and/or exchange and are consistent with the rights and
preferences attendant to such Units as set forth in the Agreement or Applicable
Law as in effect immediately prior to such Initial Public Offering and (ii)
except as otherwise provided herein, the provisions of this Agreement apply to
the Reclassified Securities and the issuer thereof as such provisions apply to
the Units and the Company, MUTATIS MUTANDIS. Notwithstanding, anything to the
contrary herein, at or prior to any Initial Public Offering the Company, at the
election of the Raytheon Member, shall redeem all of the Preferred Units in cash
by wire transfer of immediately available funds at a redemption price equal to
the Preferred Redemption Value for such Units.

        8.5    REDEMPTION. (a) The Preferred Units may be redeemed (in whole or
in part) at the option of the Raytheon Member on or after the earlier of (a) the
7th anniversary of the date hereof, (b) the date that the indebtedness incurred
pursuant to the Senior Unsecured Debt Documents has been been repaid. The
Raytheon Member shall notify the Company in writing of its

                                      -36-
<Page>

intent to exercise the rights afforded by this Section 8.5(a) and specify a date
not less than ten (10) nor more than sixty (60) days from the date of such
notice on which the Preferred Units shall be redeemed (the "Optional Redemption
Date"). The Company shall redeem on the Optional Redemption Date each Preferred
Unit being redeemed in cash by wire transfer of immediately available funds at a
redemption price (the "REDEMPTION PRICE") equal to the Preferred Redemption
Value for such Unit.

        (b)    If the funds of the Company legally available for redemption of
Preferred Units on an Optional Redemption Date are insufficient to redeem the
total number of outstanding Units entitled to redemption, the Raytheon Member
shall be entitled to any funds legally available for redemption of Units. At any
time thereafter when additional funds of the Company are legally available for
the redemption of such Units, such funds will be used at the earliest
permissible time, to redeem the balance of such Units, or such portion thereof
for which funds are then legally available. The Company shall be obligated to
use its best efforts to take such actions as may be necessary (including,
without limitation, the issuance of additional equity securities, the
revaluation or recapitalization of the Company or the consummation of a merger
or sale of assets) in order to permit the full and timely redemption of the
Preferred Units entitled to redemption. Notwithstanding the preceding and any of
the rights of the Raytheon Member hereunder, the Members acknowledge that
payments will be made pursuant to the Senior Unsecured Debt Documents prior to
any payments in respect of the redemption.

        (c)    If, for any reason, the Company fails to redeem all the Preferred
Units entitled to redemption on an Optional Redemption Date the unredeemed
Preferred Units shall remain outstanding and shall continue to have all rights
and preferences (including, without limitation, dividend and voting rights)
provided for herein and the holders of such unredeemed Preferred Units shall
have the ongoing right to be redeemed together with such rights and remedies as
may be available under Applicable Law.

        8.6    REDUCTION OF MANAGEMENT UNITHOLDERS INTERESTS. (a) Subject to
SECTION 8.6(b), in the event that prior to June 27, 2006, the employment of a
Management Unitholder by the Company on a full time basis terminates for any
reason, then as of the date of such termination of employment (the "TERMINATION
DATE"), the Management Percentage Interests of such Management Unitholder shall
be reduced by the following percentage (the "REDUCTION PERCENTAGE"):

<Table>
<Caption>
                 Termination Date                                Reduction Percentage

                 <S>                                                   <C>
                 Prior to June 27, 2002................................100%
                 After June 27, 2002 but prior to
                  June 27, 2003.........................................80%
                 After June 27, 2003 but prior to
                  June 27, 2004.........................................60%
                 After June 27, 2004 but prior to
                  June 27, 2005.........................................40%
                 After June 27, 2005 but prior to
                  June 27, 2006.........................................20%
                 After June 27, 2005.....................................0%
</Table>

                                      -37-
<Page>

        By way of example, if a Management Unitholder were to terminate his
employment with the Company on December 31, 2004, his Management Percentage
Interest would be reduced by 40%.

               (b)    Upon a Change of Control, the Reduction Percentage shall
be 0%. For purposes of this Agreement, "CHANGE OF CONTROL" means the occurrence
of any of the following events:

                      (i)    the RAH Member ceases to be the owner of a majority
        of the outstanding Management Percentage Interests; or

                      (ii)   the sale of all or substantially all of the assets
        of the Company to a third party not Affiliated with the RAH Member.

               (c)    Upon a reduction in the Management Percentage Interest of
a Management Unitholder in accordance with SECTION 8.6(a), the portion of such
Management Unitholder's Management Percentage Interest which is so reduced shall
be allocated to the RAH Member and Raytheon Member in proportion to their
respective Membership Interests. In the event of such reduction, such Management
Unitholder shall be entitled to no payment whatsoever as compensation for such
reduction in his or her Management Percentage Interest.

        8.7    PURCHASE RIGHT.

               (a)    The Company is hereby granted the right to purchase the
entire Membership Interest (or at the discretion of the Company any portion of
the Membership Interest) held by any Management Unitholder or any Permitted
Transferee of a Management Unitholder in the event the employment of such
Management Unitholder (or the transferor of such Management Unitholder) by the
Company on a full time basis terminates for any reason. The Company may exercise
this right at any time within the 60-day period immediately following the date
such Management Unitholder (or transferor of such Management Unitholder) ceases
to be providing services on a full-time basis to the Company.

               (b)    The purchase price at which the Company may exercise its
purchase right shall, after application of the Reduction Percentage pursuant to
SECTION 8.6(a) above, be the Fair Market Value of the Membership Interest of the
Management Unitholder.

               (c)    The purchase right shall be exercisable by written notice
delivered to the Management Unitholder prior to the expiration of the 60-day
purchase period referred to in SECTION 8.7(a). The notice shall indicate the
portion of the Membership Interest to be purchased, the purchase price and the
date on which the purchase is to be effected, such date to be not more than 30
days after the date of notice.

                                   ARTICLE IX

                           DISSOLUTION AND LIQUIDATION

        9.1    DURATION. The Company shall dissolve upon (i) the sale or other
disposition by the Company of all or substantially all of the assets, properties
or businesses the Company then owns, (ii) the dissolution of the Company by
action of the Board, or (iii) any other event that would cause the dissolution
of a limited liability company under the Act, unless the Company is continued to
the extent permitted by, and in accordance with, the Act (each of the foregoing
events, a "DISSOLUTION EVENT").

        9.2    LIQUIDATION OF COMPANY INTERESTS.

               (a)    Upon dissolution of the Company, the Board shall appoint
one Member (or any other Person) to serve as the "LIQUIDATOR" who shall act at
the direction of the Board, unless and until a successor Liquidator is appointed
as provided herein. The Liquidator shall agree not to resign at any time without
30 days' prior written notice. The Liquidator may be removed at any time, with
or without cause, by notice of removal and appointment of a successor Liquidator
approved by the Board. Within 30 days following the occurrence of any such
removal, a successor Liquidator may be elected by the Board. The successor
Liquidator shall succeed to all rights, powers and duties of the former
Liquidator. The right to appoint a successor or substitute Liquidator in the
manner provided herein shall be recurring and continuing for so long as the
functions and services of the Liquidator are authorized to continue under the
provisions hereof, and every reference herein to the Liquidator shall be deemed
to refer also to any such successor or substitute Liquidator appointed in the
manner herein provided. Except as expressly provided in this Article IX, the
Liquidator appointed in the manner provided herein shall have and may exercise,
without further authorization or consent of any of the parties hereto, all of
the powers conferred upon the Board under the terms of this Agreement (but
subject to all of the applicable limitations, contractual and otherwise, upon
the exercise of such powers to the extent necessary or desirable in the good
faith judgment of the Liquidator to carry out the duties and functions of the
Liquidator hereunder for and during such period of time as shall be reasonably
required in the good faith judgment of the Liquidator to complete the winding up
and liquidation of the Company as provided for herein). The Liquidator shall
receive as compensation for its services (i) no additional compensation, if the
Liquidator is an employee of the Company or any of its Subsidiaries, or (ii) if
the Liquidator is not such an employee, a reasonable fee plus out-of-pocket
costs and expenses or such other compensation as the Board may otherwise
approve.

               (b)    The Liquidator shall liquidate the assets of the Company,
and apply and distribute the proceeds of such liquidation, in the following
order of priority, unless otherwise required by mandatory provisions of
Applicable Law:

                      (i)    First, to the satisfaction (whether by payment or
        the making of reasonable provision for payment) of the Company's debts
        and obligations to its creditors, including sales commissions and other
        expenses incident to any sale of the assets of the Company and including
        the establishment of and additions to such reserves as the Liquidator
        may deem necessary or appropriate;

                                      -39-
<Page>

                      (ii)   Second, to the Unitholders, in accordance with the
        provisions of Section 5.2(a).

The reserves established pursuant to subparagraph (i) of this Section 9.2(b)
shall be paid over by the Liquidator to a bank or other financial institution,
to be held in escrow for the purpose of paying any such contingent or unforeseen
liabilities or obligations and, at the expiration of such period as the
Liquidator deems advisable, such reserves shall be distributed to the
Unitholders in the priorities set forth in this Section 9.2(b). The allocations
and distributions provided for in this Agreement are intended to result in the
Capital Account of each Unitholder immediately prior to the distribution of the
Company's assets pursuant to this Section 9.2(b) being equal to the amount that
would be distributable to such Unitholder pursuant to this Section 9.2(b). The
Company is authorized to make appropriate adjustments in the allocation of items
of income, gain, loss and deduction as necessary to cause the amount of each
Unitholder's Capital Account immediately prior to the distribution of the
Company's assets pursuant to this Section 9.2(b) to equal the amount that would
be distributable to such Unitholder pursuant to this Section 9.2(b).

               (c)    Notwithstanding the provisions of Section 9.2(b) which
require the liquidation of the assets of the Company, but subject to the order
of priorities set forth in Section 9.2(b), if upon dissolution of the Company
the Board determines that an immediate sale of part or all of the Company's
assets would be impractical or could cause undue harm to the Unitholders, then
the Board may, in its discretion, defer the liquidation of any assets except
those necessary to satisfy Company liabilities and reserves, and may, in its
discretion, distribute to the Unitholders, in lieu of cash, as tenants in common
and in accordance with the provisions of Section 9.2(b), undivided interests in
such Company assets as the Liquidator deems reasonable and equitable and subject
to any agreements governing the operating of such properties at such time. For
purposes of any such distribution, the Board will determine the Fair Market
Value of any property to be distributed.

               (d)    A reasonable time will be allowed for the orderly winding
up of the business and affairs of the Company and the liquidation of its assets
pursuant to Section 9.2(b) in order to minimize any losses otherwise attendant
upon such winding up. Distributions upon liquidation of the Company (or any
Unitholder's interest in the Company) and related adjustments will be made by
the end of the Fiscal Year of the liquidation (or, if later, within 90 days
after the date of such liquidation) or as otherwise permitted by Treasury
Regulation Section 1.704-1(b)(2)(ii)(b).

               (e)    The Company shall terminate when all of the assets of the
Company have been distributed in accordance with this Section 9.2 and the
Certificate has been canceled in the manner required by the Act.

                                    ARTICLE X

                                BOOKS AND RECORDS

        10.1   BOOKS. The Company shall maintain complete and accurate books of
account of the Company's affairs at the Company's principal office, which books
shall be open to inspection

                                      -40-
<Page>

by any Member (or its authorized representative) to the extent required by the
Act (unless provided otherwise in this Agreement).

        10.2   TAX ALLOCATIONS AND REPORTS.

               (a)    Not later than seven calendar months after the end of each
Fiscal Year, the Board shall cause the Company to furnish each Unitholder an
Internal Revenue Service Form K-1 and any similar form required for the filing
of state or local income tax returns for such Unitholder for such Fiscal Year.
Upon the written request of any such Unitholder and at the expense of such
Unitholder, the Company will use reasonable efforts to deliver or cause to be
delivered any additional information necessary for the preparation of any state,
local and foreign income tax return which must be filed by such Unitholder.

               (b)    The Raytheon Member shall determine whether to make or
revoke any available election pursuant to the Code. Each Unitholder will, upon
request, supply the information necessary to give proper effect to any such
election.

               (c)    To the extent applicable, the Company hereby designates
the Raytheon Member to act as the "TAX MATTERS PARTNER" (as defined in Section
6231(a)(7) of the Code) in accordance with Sections 6221 through 6233 of the
Code. The Tax Matters Partner is authorized and required to represent the
Company (at the Company's expense) in connection with all examinations of the
Company's affairs by tax authorities, including resulting administrative and
judicial proceedings, and to expend Company funds for professional services and
costs associated therewith; PROVIDED, that the Tax Matters Partner may be
removed and replaced by, and shall act in such capacity at the direction of, the
Board. Each Unitholder agrees to cooperate with the Tax Matters Partner and to
do or refrain from doing any or all things reasonably requested by the Tax
Matters Partner with respect to the conduct of such proceedings. Subject to the
foregoing proviso, the Tax Matters Partner will have reasonable discretion to
determine whether the Company (either on its own behalf or on behalf of the
Unitholders) will contest or continue to contest any tax deficiencies assessed
or proposed to be assessed by any taxing authority. Any deficiency for taxes
imposed on any Unitholder (including penalties, additions to tax or interest
imposed with respect to such taxes) will be paid by such Unitholder, and if paid
by the Company, will be recoverable from such Unitholder (including by offset
against distributions otherwise payable to such Unitholder). The Tax Matters
Partner shall take reasonable action to cause each other Unitholder having at
least a 20% of the Common Units to be treated as a "notice partner" within the
meaning of Section 6231(a)(8) of the Code. Each such Unitholder shall have the
right to participate in any administrative proceeding and any discussions with
the Internal Revenue Service.

               (d)    Each of the Members and the Company shall take no action
inconsistent with, and shall make or cause to be made all applicable elections
with respect to (i) the treatment of the Company as a partnership; (ii) the
treatment of the Company as not a publicly traded partnership for federal income
tax purposes; (iii) the treatment of Raytheon as having contributed assets of
Raytheon Aerospace Company without recognition of gain at the time of such
contribution for purposes of the Code; (v) the treatment of RAH entity as having
contributed $42,000,000 of cash to the Company in a Section 721 contribution;
(v) the allocation of debt to Raytheon for purposes of Section 752 of the Code
in accordance with Section 6.5. and (vi) the treatment of

                                      -41-

any Class B Unitholder as a person other than a person described in Treasury
Regulation Section 1.752-2(c) (other than a person described in Treasury
Regulation Section 1.752-2(d)).

                                   ARTICLE XI

                         EXCULPATION AND INDEMNIFICATION

        11.1   EXCULPATION AND INDEMNIFICATION.

               (a)    No Member, Representative or any direct or indirect
officer, director, stockholder or partner of a Member (each, an "INDEMNITEE"),
shall be liable, responsible or accountable in damages or otherwise to the
Company, any Member, or to any Unitholder, for any act or failure to act by such
Indemnitee in connection with the conduct of the business of the Company, or by
any other such Indemnitee in performing or participating in the performance of
the obligations of the Company, so long as such Indemnitee acted in the good
faith belief that such action or failure to act was in the best interests, or
not opposed to the best interests, of the Company and/or its Subsidiaries and
such action or failure to act was not in violation of this Agreement and did not
constitute gross negligence or willful misconduct. Except as otherwise required
by the Act, no Person who is a Member, Representative, an Officer, or any
combination of the foregoing, shall be personally liable under any judgment of a
court, or in any other manner, for any debt, obligation, or liability of the
Company, whether that liability or obligation arises in contract, tort, or
otherwise, solely by reason of being a Member, or Representative, an Officer, or
any combination of the foregoing. Nothing contained in this Agreement shall
affect the rights of the Company against any Member pursuant to the terms and
conditions of the Combination Agreement.

               (b)    The Company shall indemnify and hold harmless each
Indemnitee to the fullest extent permitted by law against losses, damages,
liabilities, costs or expenses (including reasonable attorney's fees and
expenses and amounts paid in settlement) incurred by any such Indemnitee in
connection with any action, suit or proceeding to which such Indemnitee may be
made a party or otherwise involved or with which it shall be threatened by
reason of its being a Member, Representative or any direct or indirect officer,
director, stockholder or partner of a Member, or while acting as (or on behalf
of) a Member on behalf of the Company or in the Company's interest. Such
attorney's fees and expenses shall be paid by the Company as they are incurred
upon receipt, in each case, of an undertaking by or on behalf of the Indemnitee
to repay such amounts if it is ultimately determined that such Indemnitee is not
entitled to indemnification with respect thereto.

               (c)    The right of an Indemnitee to indemnification hereunder
shall not be exclusive of any other right or remedy that a Member,
Representative or Officer may have pursuant to Applicable Law or this Agreement.

        11.2   INSURANCE. The Company shall have the power to purchase and
maintain insurance on behalf of any Indemnitee or any Person who is or was an
agent of the Company against any liability asserted against such Person and
incurred by such Person in any such capacity, or arising out of such Person's
status as an agent, whether or not the Company would have the

                                      -42-
<Page>

power to indemnify such Person against such liability under the provisions of
Section 11.1 or under Applicable Law.

        11.3   INDEMNIFICATION AND REIMBURSEMENT FOR PAYMENTS ON BEHALF OF A
UNITHOLDER.

               (a)    If the Company is obligated to pay any amount to a
Governmental Authority or to any other Person (and makes such payment or will
make such a payment within 30 days of charging the Capital Account of the Member
pursuant to the following sentences and either providing notification of an
obligation to indemnify under (i) below or offsetting a distribution pursuant to
(ii) below) on behalf of (or in respect of an obligation of) a Unitholder
(including, without limitation, federal, state and local withholding taxes
imposed with respect to foreign Members, and state unincorporated business
taxes, etc.), then such Unitholder (the "CHARGED MEMBER") shall indemnify the
Company in full for the entire amount paid (including, without limitation, any
interest, penalties and expenses associated with such payment). The amount to be
indemnified shall be charged against the Capital Account of the Charged Member,
and, at the option of the Board, either:

                      (i)    promptly upon notification of an obligation to
        indemnify the Company, the Charged Member shall make a cash payment to
        the Company equal to the full amount to be indemnified (and the amount
        paid shall be added to the Charged Member's Capital Account but shall
        not be deemed to be a Capital Contribution hereunder); or

                      (ii)   the Company shall reduce current or subsequent
        distributions that would otherwise be made to the Charged Member until
        the Company has recovered the amount to be indemnified (PROVIDED that
        the amount of such reduction shall be deemed to have been distributed
        for all purposes of this Agreement, but such deemed distribution shall
        not further reduce the Charged Member's Capital Account).

               (b)    A Charged Member's obligation to make contributions to the
Company under this Section 11.3 shall survive the termination, dissolution,
liquidation and winding up of the Company, and for purposes of this Section
11.3, the Company shall be treated as continuing in existence. The Company may
pursue and enforce all rights and remedies it may have against each Charged
Member under this Section 11.3, including instituting a lawsuit to collect such
contribution with interest calculated at a rate equal to the Base Rate plus six
percentage points per annum (but not in excess of the highest rate per annum
permitted by law).

                                   ARTICLE XII

                                  MISCELLANEOUS

        12.1   CONFIDENTIALITY. By executing this Agreement, each Member
expressly agrees, at all times during the term of the Company and thereafter and
whether or not at that time it is a Member of the Company, (unless the prior
written consent of the Company is obtained, which prior consent shall not be
unreasonably withheld) to maintain the confidentiality of, and not to disclose
to any Person other than the Company, another Member or a person designated by
the Company, any information obtained from the Company or its representatives
that is not generally available or known to the public and which has not been
previously disclosed by any Member

                                      -43-
<Page>

without a confidentiality agreement relating to the identity of any Member, the
business, financial structure, financial position or financial results, clients
or affairs of the Company; PROVIDED, that each Member may deliver or disclose
confidential information to (i) its directors, officers, employees, agents,
attorneys and Affiliates (to the extent such disclosure reasonably relates to
the administration of the investment represented by its interest in the Company
and such Persons agree to comply with the terms of this Section), (ii) its
financial advisors and other professional advisors who agree to comply with the
terms of this Section, (iii) any Person to which it sells or offers to sell its
interest in the Company or any part thereof or any participation therein in
accordance with the transfer restrictions contained in this Agreement (if such
Person has agreed in writing prior to its receipt of such confidential
information to be bound by the provisions of this Section), (iv) any
Governmental Authority or other regulatory or self regulatory authority having
jurisdiction over a Member or any nationally recognized rating agency that
requires access to information about a Member's investment portfolio, or (v) any
other Person to which such delivery or disclosure may be necessary or advisable
(a) to effect compliance with any law, rule, regulation or order applicable to a
Member, including the requirements of any stock exchange, (b) in response to any
subpoena or other legal process, or (c) in connection with any litigation to
which a Member is a party.

        12.2   WAIVER OF JURY TRIAL. Each of the parties hereto knowingly,
intentionally and voluntarily waives to the fullest extent permitted by law any
right it may have to trial by jury in respect of any claim, demand, action or
cause of action based on, or arising out of, under or in connection with this
Agreement, or any course of conduct, course of dealing, verbal or written
statement or action of any party hereto, in each case whether now existing or
hereafter arising, and whether in contract, tort, equity or otherwise. The
parties to this Agreement each hereby agrees that any such claim, demand, action
or cause of action shall be decided by court trial without a jury and that the
parties to this Agreement may file an original counterpart or a copy of this
Agreement with any court as evidence of the consent of the parties hereto to the
waiver of their right to trial by jury.

        12.3   GOVERNING LAW. ALL ISSUES AND QUESTIONS CONCERNING THE
APPLICATION, CONSTRUCTION, VALIDITY, INTERPRETATION AND ENFORCEMENT OF THIS
AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE
STATE OF DELAWARE, INCLUDING THE DELAWARE LIMITED LIABILITY COMPANY ACT,
DELAWARE CODE, TITLE 6, SECTIONS 18-101, ET SEQ., AS IN EFFECT FROM TIME TO
TIME, 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.

        12.4   DESCRIPTIVE HEADINGS. The descriptive headings of this Agreement

Agreement.

        12.5   SEVERABILITY. Whenever possible, each provision of this Agreement
shall 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 shall not affect
any other provision or any other jurisdiction, but this Agreement shall be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision had never been contained herein. The Members
shall negotiate in good faith to replace any provision so held to

                                      -44-
<Page>

be invalid or unenforceable so as to implement most effectively the transactions
contemplated by such provision in accordance with the original intent of the
Members signatory hereto.

Agreement by the unanimous written consent of the Raytheon Member and the RAH

          SECTION 8.6(b), in the event that prior to June 27, 2006 or the fifth
          anniversary of the date the subject Management Unitholder became a
          full-time employee of the Company or any of its Subsidiaries or an RAH
          Representative, as the case may be (the "VESTING COMMENCEMENT DATE"),
          whichever is later, the services of a Management Unitholder to the
          Company either as a full-time employee or an RAH Representative
          terminate for any reason, then as of the date of such termination (the
          "TERMINATION DATE"), the Management Percentage Interest of such
          Management Unitholder shall be reduced by the following percentage
          (the "REDUCTION PERCENTAGE"):

                                        3
<Page>

                        TERMINATION DATE                             REDUCTION
                                                                     PERCENTAGE

            Prior to and including June 27, 2002 or the
            first anniversary of the Vesting
            Commencement Date, whichever is later                       100%

            After June 27, 2002 or the first
            anniversary of the Vesting Commencement
            Date, whichever is later, but prior to and
            including June 27, 2003 or the second
            anniversary of the Vesting Commencement
            Date, whichever is later                                     80%

            After June 27, 2003 or the second
            anniversary of the Vesting Commencement
            Date, whichever is later, but prior to and
            including June 27, 2004 or the third
            anniversary of the Vesting Commencement
            Date, whichever is later                                     60%

            After June 27, 2004 or the third
            anniversary of the Vesting Commencement
            Date, whichever is later, but prior to and
            including June 27, 2005 or the fourth
            anniversary of the Vesting Commencement
            Date, whichever is later                                     40%

            After June 27, 2005 or the fourth
            anniversary of the Vesting Commencement
            Date, whichever is later, but prior to and
            including June 27, 2006 or the fifth
            anniversary of the Vesting Commencement
            Date, whichever is later                                     20%

            After June 27, 2006 or the fifth
            anniversary of the Vesting Commencement
            Date, whichever is later                                      0%

          By way of example, if a Management Unitholder whose Vesting
          Commencement Date was on or prior to June 27, 2001 were to either
          terminate his employment (or have his employment terminated) with the
          Company or cease serving as an RAH Representative for any reason on
          December 31, 2004, his Management Percentage Interest would be reduced
          by 40%.

                 (b)  Upon a Change of Control, the Reduction Percentage shall
          be 0%. For purposes of this Agreement, "CHANGE OF CONTROL" means the
          occurrence of any of the following events:

                      (i)   the RAH Member ceases to be the owner of a majority
                 of the outstanding Senior Common Units; or

                      (ii)  the sale of all or substantially all of the assets
                 of the Company to a third party that is not an Affiliate of the
                 RAH Member.

                 (c)  In the event that the duties and responsibilities of a
          Management Unitholder to the Company or any of its Subsidiaries are
          changed, the Management Percentage Interest of such Management
          Unitholder may be increased or decreased by an amount determined in
          the sole discretion of the RAH Member, subject to the last sentence of
          Section 8.2(d)(ii).

                 (d)  Upon a reduction in the Management Percentage Interest of
          a Management Unitholder in accordance with SECTION 8.6(a) or Section
          8.6(c), the portion of such Management Unitholder's Management
          Percentage Interest which is so reduced shall be allocated to the RAH
          Member and Raytheon Member in proportion to their respective
          Membership Interests. In the event of such reduction, such Management
          Unitholder shall be entitled to no payment whatsoever as compensation
          for such reduction in his or her Management Percentage Interest."
