ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                  CONDITION AND RESULTS OF OPERATIONS.

First Quarter 1997 versus 1996

Raytheon Company reported first quarter earnings of $183.4 million, or $.78 per
share, on record first quarter sales of $2.899 billion. For last year's first
quarter, earnings were $186.5 million, or $.78 per share, on sales of $2.788
billion. Operating income in this year's first quarter was $339.5 million, up
15.4 percent from $294.1 million for the first quarter of 1996, compared to a
4.0 percent increase in revenues over this same period.

The first quarter earnings of $183.4 million, or $.78 per share, were achieved
despite having higher interest expense of $15 million in the quarter and lower
non-operating income of $34 million due to first quarter 1996 nonrecurring
income adjustments related to a federal income tax refund claim and the release
of a contingency reserve associated with the sale of a business.

As announced in January 1997, Raytheon has entered into definitive agreements,
subject to approvals, to purchase the assets of Texas Instruments' (TI) defense
operations and to merge with Hughes Electronics' defense operations.

The Electronics segment led Raytheon's increase in first quarter sales and
operating income, as segment sales rose 12.8 percent and segment operating
income increased 22.5 percent, compared with the first quarter a year ago.
Raytheon Electronic Systems, based primarily in Massachusetts, was up in both
sales and operating profits for the first time in 15 quarters. Raytheon
E-Systems higher operating income reflects both margin improvement and the
acquisition of Chrysler Technologies' aircraft modification and defense
electronics businesses. In addition, sales and operating income were up in
continuing operations for the commercial electronics group.

The Engineering and Construction segment reported operating margins of 7.8
percent on revenues of $681 million. While sales remained constrained due to the
pace of international turnkey projects, the group made steady quarter
improvement over its third and fourth quarter operating margin comparisons.

The Aircraft segment reported a 20.7 percent increase in operating income over
the first quarter of 1996, resulting from a favorable sales mix within a
slightly lower sales base.

The Major Appliances segment reported first quarter sales of $341 million and
operating profits of $13 million. Sales were up for refrigerators and self-clean
cooking products. These sales increases were offset by lower shipments of home
appliance room air conditioners. Excluding "manual-clean" cooking ranges, for
which a charge was taken in the third quarter of 1996 to exit the business,
first quarter revenues were flat as compared with the first quarter 1996
results.

Raytheon announced in February, 1997 that it is evaluating strategic
alternatives for the Appliance Group, which may result in the sale or merger of
the group at some time in the future. The company has retained an advisor to
assist with this evaluation. The decision to undertake this strategic
reassessment was made in the context of Raytheon's financial priorities, and the
belief that the Appliance Group may have greater value to another company with
more focus on the markets served by the group.

A leader in the field of wide-area environmental surveillance, Raytheon
won an international competition to develop and produce the System for the
Surveillance of the Amazon (SIVAM) -- an environmental monitoring system that
will help Brazil protect natural resources, sustain economic growth and support
proper land use, conservation and development in the Amazon region. On March 14,
1997, Raytheon announced that the SIVAM contract had been signed by the
government of Brazil and that all financing agreements for the program had been
finalized. The system is based on an integrated network of telecommunications,
remote satellite sensing and imagery and ground-based and airborne sensors
controlled by regional and national coordination centers.

         Three lawsuits have been filed seeking to set aside the SIVAM contract
between the Government of Brazil and Raytheon on various grounds. The lower
court in one of these actions has issued a decision declaring the contract
invalid and issued an injunction enjoining contract performance. The President
of the Regional Court has suspended the lower court's decision and the
injunction. Raytheon is appealing the lower court's decision.

Sales to the U. S. Government, including Foreign Military Sales, were $1.320
billion, an increase of $174 million or 15.2 percent from the comparable quarter
of 1996. U.S. Government sales were 45.5 percent of consolidated net sales in 
1997 compared with 41.4 percent in 1996.

Administration and selling expenses decreased to $260.1 million in 1997 from
$264.7 million in 1996 due principally to the sale of Xyplex in April, 1996.

Research and development expenses decreased to $79.1 million in 1997 from $87.5
million in 1996.  The decrease was due to lower spending at the Electronics
segment and the sale of Xyplex.

Operating income was $339.5 million or 11.7 percent of sales versus $294.1
million or 10.5 percent of sales in 1996.  Operating income in 1997 was 15.4
percent above 1996.

Interest expense increased to $68.9 million in 1997 from $54.2 million in 1996.
The increase was due principally to the higher debt level from the acquisition
of Chrysler Technologies and Rust Engineering in the second quarter of 1996.

Interest and dividend income declined to $5.7 million in 1997 from $20.3 million
in 1996.  The 1996 results included accrued interest before tax on a
retroactive federal income tax refund claim.

Other income, net for 1997 was $2.1 million versus $21.8 million in 1996.  The
1996 results included $20 million before tax from the release of a contingency
reserve associated with the sale of a business.

The 1997 effective tax rate of 34.1 percent reflects the statutory rate of 35
percent reduced principally by Foreign Sales Corporation tax credits and
incremental research and development tax credits applicable to certain
government contracts, partially offset by non-deductible amortization of
goodwill.

For reasons discussed above, net income of $183.4 million was down $3.1 million
or 1.6 percent from 1996.

Earnings per common share for the first quarter of 1997 were $.78 which was
equal to the 1996 earnings per common share. The average number of shares
outstanding during the first quarter of 1997 was 236.3 million versus 240.1
million in 1996. During the quarter outstanding shares were increased by
approximately 186 thousand shares due to the exercise of stock options and the
conversion of the present value of directors pension benefit into shares of the
company's common stock. These were partially offset by the repurchase of 149
thousand shares in the open market at a cost of $6.8 million.

On February 22, 1995, the Board of Directors authorized the repurchase of up to
12 million shares of the company's common stock.  There have been 9.5 million
shares purchased under this authorization through the first quarter of 1997.

The book value of common shares outstanding at the end of the period was $19.97
as compared with $19.46 at December 31, 1996, and $18.16 at March 31, 1996.

During the first quarter of 1997 there was a negative cash flow from operations
of $5.1 million. Net income plus depreciation and amortization provided a
positive cash flow of $277.6 million but this was more than offset by increases
in contracts in process and inventories. During the quarter the company sold
$327.1 million of receivables, including general and commuter aviation long-term
receivables and a fractional ownership in a defined pool of engineering and
construction and appliance receivables, to a bank syndicate and other financial
institutions. During the quarter funds were used for additions to property,
plant and equipment of $108.4 million and dividend payments of $47.2 million.
Principally as a result of the above, short-term debt increased by $176.5
million.

Debt, net of cash and marketable securities, was $3,768 million at March 30,
1997, as compared with $3,588 million at December 31, 1996, and $3,011 million
at March 31, 1996. Net debt as a percentage of total capitalization was 44.4
percent at March 30, 1997, as compared with 43.8 percent at December 31, 1996,
and 40.9 percent at March 31, 1996.

Capital expenditures were $108.4 million in the first quarter of 1997 versus
$104.0 million in the first quarter of 1996. Capital expenditures in 1997 are
expected to be moderately above the 1996 level, excluding the effect of
acquisitions.

Dividends declared to stockholders in the first quarter of 1997 were $47.2
million versus $47.9 million in 1996.  The dividend rate was $.20 per quarter in
both quarters.

Total employment was 74,000 at March 30, 1997, as compared with 75,300 at
December 31, 1996, and 72,900 at March 31, 1996. The increase from March 31,
1996, is due principally to acquisitions of Chrysler Technologies and Rust
Engineering in the second quarter of 1996 partially offset by reductions in the
Electronics and Engineering and Construction segments and the sale of Xyplex in
April, 1997.

In January 1997, Raytheon entered into definitive agreements to purchase the
assets of Texas Instruments' (TI) defense operations for $2.95 billion in cash
and to merge with Hughes Electronics' defense operations, with the combined
company to be called Raytheon. The Hughes transaction is valued at $9.5 billion,
comprised of approximately $5.1 billion in common stock and $4.4 billion in debt
to be assumed by the merged company. The notes to the financial statements in
Raytheon's 1996 Annual Report, the Annual Report on Form 10-K for the year ended
December 31, 1996, and the Current Report on Form 8-K dated January 17, 1997,
provide a more complete description of the Hughes transaction.

<PAGE>
                                       10

The two transactions are subject to regulatory approvals, including
Hart-Scott-Rodino antitrust review, with the Hughes transaction subject to a
favorable ruling by the Internal Revenue Service and approval by Raytheon,
General Motors (GM) and GM "H" stockholders.

Credit ratings for the company, based on the proposed acquisitions, have been
lowered by Moody's to P-2 for short-term borrowing and A-3 for senior debt as of
January 16, 1997 with negative implications, by Standard and Poor's to A-3 for
short-term borrowing and BBB for senior debt as of January 17, 1997 with
negative implications and by Duff & Phelps to D-2 for short-term borrowing and
BBB+ for senior debt as of February 26, 1997. Moody's and Standard and Poor's
have reviewed the detailed financials associated with these transactions and
will issue final ratings in the near term. The company expects that its cash
flow from operations and asset reductions will be sufficient to maintain
investment grade credit ratings and available debt financing will be sufficient
to meet any additional funding requirements in 1997.

The company announced in the third quarter of 1996 that it would exit the
manual-clean range market and dispose of the assets related to that operation,
including its facility located in Delaware, Ohio, and recorded a $34.0 million
pre-tax charge for this closing. The after-tax effect was $22.1 million or $.09
per share.

The company enters into interest rate swaps and locks and foreign currency
forward agreements with commercial and investment banks to reduce the impact of
changes in interest rates and foreign exchange rates on long-term debt and on
purchases, sales and financing arrangements with lenders, vendors, customers and
foreign subsidiaries. The company meets its working capital requirements mainly
with variable rate short-term financing. Interest rate swaps are primarily used
to provide purchasers of the company's products with fixed financing terms over
extended time periods. The company also enters into foreign exchange forward
contracts to minimize fluctuations in the value of payments due to international
vendors and the value of foreign currency denominated receipts. The hedges used
by the company are directly related to a particular asset, liability, or
transaction for which a firm commitment is in place. Swaps and foreign exchange
contracts are normally held to maturity and no exchange traded or
over-the-counter instruments have been purchased. The impact on the financial
position, liquidity, and results of operations from likely changes in foreign
exchange and interest rates is immaterial due to the minimizing of risk through
the hedging of transactions related to specific assets, liabilities, or
commitments.

Recurring costs associated with the company's environmental compliance program
are not material and are expensed as incurred. Capital expenditures in
connection with environmental compliance are immaterial. The company is involved
in various stages of investigation and cleanup relative to remediation of
various sites. All appropriate costs incurred in connection therewith have been
expensed. Due to the complexity of environmental laws and regulations, the
varying costs and effectiveness of alternative cleanup methods and technologies,
the uncertainty of insurance coverage, and the unresolved extent of the
company's responsibility, it is difficult to determine the ultimate outcome of
these matters. However, in the opinion of management, any additional liability
will not have a material effect on the company's financial position, liquidity,
or results of operations after giving effect to provisions already recorded.

                                       11

The company adopted Statement of Financial Accounting Standard No. 125,
Accounting for Transfers and Servicing of Financial Assets and Extinguishments
of Liabilities, in 1997. The adoption did not have a material effect on the
company's financial position or results of operations.

The company adopted the American Institute of Certified Public Accountants'
Statement of Position 96-1, Environmental Remediation Liabilities, in 1997. The
adoption of the standard did not have a material effect on the company's
financial position or results of operations.

The company will adopt Statement of Financial Accounting Standard No. 128,
Earnings per Share, in the fourth quarter of 1997. The adoption is not expected
to have a material effect on the company's financial position, results of
operations or earnings per share.

Forward Looking Statements

Statements which are not historical facts contained in this report are
forward-looking statements that involve risks and uncertainties. These risks
include, in addition to the specific uncertainties referenced in this report,
the ability to realize anticipated cost efficiencies from the acquisition of the
defense systems and electronics business of Texas Instruments and the merger of
the Company with the defense business of Hughes Electronics Corporation, the
effect of worldwide political and market conditions, the impact of competitive
products and pricing and the timing of awards and contracts. Further information
regarding the factors that could cause actual results to differ materially from
projected results can be found in Raytheon's reports filed with the SEC,
including our Current Reports Form 8-K filed on January 6, 1997 and January 17,
1997, respectively, and our Annual Report on Form 10-K for the fiscal year ended
December 31, 1996.

    CREDIT AGREEMENT dated as of May 2, 1997 (this "Agreement"), among RAYTHEON
COMPANY, a Delaware corporation (the "Borrower"), the Lenders (as defined in
Article I), BANCAMERICA SECURITIES, INC., as Syndication Agent (in such
capacity, the "Syndication Agent"), CANADIAN IMPERIAL BANK OF COMMERCE and
CREDIT SUISSE FIRST BOSTON, as Documentation Agents (in such capacity, each a
"Documentation Agent" and, collectively, the "Documentation Agents"), and THE
CHASE MANHATTAN BANK, a New York banking corporation, as administrative agent
(in such capacity, the "Administrative Agent") for the Lenders.

         Pursuant to an asset purchase agreement dated as of January 4, 1997
(the "Asset Purchase Agreement"), between the Borrower and Texas Instruments
Incorporated, a Delaware corporation ("TI"), the Borrower intends, subject to
the conditions set forth in the Asset Purchase Agreement (such term and each
other capitalized term used but not defined herein having the meaning given to
it in Article I), to acquire all the assets and assume certain of the
liabilities (the "TI Acquisition") of the defense business of TI. The Borrower
also intends, subject to the conditions set forth in the Hughes Merger
Agreement, to combine its business with the defense business of HE Holdings,
Inc., a Delaware corporation ("Hughes"), by merging (the "Hughes Merger") with
and into Hughes pursuant to an Agreement and Plan of Merger dated as of January
16, 1997 (the "Hughes Merger Agreement"), between the Borrower and Hughes. The
Borrower has requested the Lenders to extend credit in the form of Revolving
Loans at any time and from time to time prior to the Maturity Date, in an
aggregate principal amount at any time outstanding not in excess of
$4,000,000,000. The Borrower has requested the Lenders to provide a procedure
pursuant to which the Borrower may invite the Lenders to bid on an uncommitted
basis on short-term Borrowings by the Borrower. The proceeds of the Loans are to
be used (a) to finance the TI Acquisition, (b) to repay in full all outstanding
amounts under the Borrower's existing Credit Agreement dated as of April 28,
1995 (as amended, the "Existing Credit Agreement"), and (c) to pay related fees
and expenses. In addition, the proceeds of the Loans may be used to provide
working capital and for other general corporate purposes of the Borrower,

         Less than Baa3 by Moody's        .375%                .175%


     For purposes of the foregoing, (i) if either Moody's or S&P shall not
have in effect a rating for the Index Debt (other than by reason of the
circumstances referred to in the last sentence of this paragraph), then such
rating agency shall be deemed to have established a rating in Category 7; (ii)
if the ratings established or deemed to have been established by Moody's and S&P
for the Index Debt shall fall within different Categories, the Applicable
Percentage shall be based on the higher of the two ratings unless the ratings
differ by more than one category, in which case the governing rating shall be
the rating next below the higher of the two; (iii) until the aggregate
commitments under this Agreement, the 364-day Agreement and the Hughes Credit
Agreements are reduced below $8,000,000,000, the Eurodollar Spread will be
increased by 0.05% at all times that the aggregate amounts outstanding hereunder
and under the 364-day Agreement exceed 66 2/3% of the aggregate commitments
(whether used or unused) hereunder and under the 364-day Agreement; and (iv) if
the ratings established or deemed to have been established by Moody's and S&P

effective date of the next such change. If the rating system of Moody's or S&P
shall change, or if either such rating agency shall cease to be in the business
of rating corporate debt obligations, the Borrower and the Lenders shall
negotiate in good faith to amend this definition to reflect such changed rating
system or the non-availability of ratings from such rating agency and, pending
the effectiveness of any such amendment, the Applicable Percentage shall be
determined by reference to the rating most recently in effect prior to such
change or cessation.

         "Asset Sale" shall mean the sale, assignment, transfer or other

relying upon the representations and warranties herein set forth, each Lender

                                       15

         SECTION 2.02. Loans. (a) Each Revolving Loan shall be made as part of a
Borrowing consisting of Loans made by the Lenders ratably in accordance with
their respective Commitments; provided, however, that the failure of any Lender
to make any Loan shall not in itself relieve any other Lender of its obligation
to lend hereunder (it being understood, however, that no Lender shall be
responsible for the failure of any other Lender to make any Loan required to be
made by such other Lender). Each Competitive Loan shall be made in accordance
with the procedures set forth in Section 2.03. The Loans comprising any
Borrowing shall be in an aggregate principal amount that is (i) an integral
multiple of $1,000,000 and not less than $10,000,000 or (ii) equal to the
remaining available balance of the Total Commitment.

         (b) Subject to Sections 2.09 and 2.15, each Competitive Borrowing shall
be comprised entirely of Eurodollar Competitive Loans or Fixed Rate Loans, and
each Revolving Credit Borrowing shall be comprised entirely of ABR Loans or
Eurodollar Loans as the Borrower may request pursuant to Section 2.03 or 2.04,
as applicable. Each Lender may at its option make any Eurodollar Loan by causing
any domestic or foreign branch or Affiliate of such Lender to make such Loan;
provided that any exercise of such option shall not affect the obligation of the
Borrower to repay such Loan in accordance with the terms of this Agreement.
Borrowings of more than one Type may be outstanding at the same time; provided,
however, that the Borrower shall not be entitled to request any Borrowing that,
if made, would result in more than 15 Eurodollar Borrowings outstanding
hereunder at any time. For purposes of the foregoing, Borrowings having
different Interest Periods, regardless of whether they commence on the same
date, shall be considered separate Borrowings.

         (c) Each Lender shall make each Loan to be made by it hereunder on the
proposed date thereof by wire transfer of immediately available funds to such
account in New York City as the Administrative Agent may designate not later
than 11:00 a.m., New York City time, and the Administrative Agent shall by 12:00
(noon), New York City time, credit the amounts so received to an account with
the Administrative Agent designated by the Borrower in the applicable Borrowing
Request or Competitive Bid Request, which account must be in the name of the
Borrower or, if a Borrowing shall not occur on such date because any condition
precedent herein specified shall not have been met, return the amounts so
received to the respective Lenders.

         (d) Unless the Administrative Agent shall have received notice from a
Lender prior to the date of any Borrowing that such Lender will not make
available to the Administrative Agent such Lender's portion of such Borrowing,
the Administrative Agent may assume that such Lender has made such portion
available to the Administrative Agent on the date of such Borrowing in
accordance with paragraph (c) above and the Administrative Agent may, in
reliance upon such assumption, make available to the Borrower on such date a
corresponding amount. If the Administrative Agent shall have so made funds
available then, to the extent that such Lender shall not have made such portion
available to the Administrative Agent, such Lender and the Borrower severally
agree to repay to the Administrative Agent within one Business Day of demand
therefor such corresponding amount together with interest thereon, for each day
from the date such amount is made available to the Borrower until the date such
amount is repaid to the Administrative Agent at (i) in the case of the
Borrower, the interest rate applicable at the time to the Loans comprising such
Borrowing and (ii) in the case of such Lender, a rate determined by the
<PAGE>
                                       16

Administrative Agent to represent its cost of overnight or short-term funds
(which determination shall be conclusive absent manifest error). If such Lender
shall repay to the Administrative Agent such corresponding amount, such amount
shall constitute such Lender's Loan as part of such Borrowing for purposes of
this Agreement.

         (e) Notwithstanding any other provision of this Agreement, the Borrower
shall not be entitled to request any Borrowing if the Interest Period requested
with respect thereto would end after the Maturity Date.

         SECTION 2.03. Competitive Bid Procedure. (a) In order to request
Competitive Bids, the Borrower shall hand deliver or telecopy to the
Administrative Agent a duly completed Competitive Bid Request (i) in the case of
a Eurodollar Competitive Borrowing, not later than 10:00 a.m., New York City
time, four Business Days before the proposed date of such Borrowing and (ii) in
the case of a Fixed Rate Borrowing, not later than 10:00 a.m., New York City
time, one Business Day before the proposed date of such Borrowing. A Competitive
Bid Request shall not be made within five Business Days after the date of any
previous Competitive Bid Request. No ABR Loan shall be requested in, or made
pursuant to, a Competitive Bid Request. A Competitive Bid Request that does not
conform substantially to the format of Exhibit D-1 may be rejected by the
Administrative Agent and the Administrative Agent shall notify the Borrower of
such rejection as promptly as practicable. Each Competitive Bid Request shall
refer to this Agreement and specify (i) whether the Borrowing being requested is
to be a Eurodollar Competitive Borrowing or a Fixed Rate Borrowing; (ii) the
date of such Borrowing (which shall be a Business Day); (iii) the number and the
location of the account to which funds are to be disbursed (which shall be an
account that complies with the requirements of Section 2.02(c)); (iv) the
aggregate principal amount of such Borrowing, which shall be a minimum of
$10,000,000 and an integral multiple of $1,000,000 and not greater than the
Total Commitment then available; and (v) the Interest Period with respect
thereto (which may not end after the Maturity Date). Promptly after its receipt
of a Competitive Bid Request that is not rejected, the Administrative Agent
shall by telecopy in the form set forth in Exhibit D-2 invite the Lenders to bid
to make Competi tive Loans pursuant to the Competitive Bid Request.

         (b) Each Lender may make one or more Competitive Bids to the Borrower
responsive to a Competitive Bid Request. Each Competitive Bid by a Lender must
be received by the Administrative Agent by telecopy in the form of Exhibit D-3,
(i) in the case of a Eurodollar Competitive Borrowing, not later than 9:30 a.m.,
New York City time, three Business Days before the proposed date of such
Competitive Borrowing and (ii) in the case of a Fixed Rate Borrowing, not later
than 9:30 a.m., New York City time, on the proposed date of such Competitive
Borrowing. Competitive Bids that do not conform substantially to the format of
Exhibit D-3 may be rejected by the Administrative Agent, and the Administrative
Agent shall notify the applicable Lender as promptly as practicable. Each
Competitive Bid shall refer to this Agreement and specify (x) the principal
amount (which shall be a minimum of $5,000,000 and an integral multiple of
$1,000,000 and which may equal the entire principal amount of the Competitive
Borrowing requested by the Borrower) of the Competitive Loan or Loans that the
Lender is willing to make, (y) the Competitive Bid Rate or Rates at which the
Lender is prepared to make such Loan or Loans and (z) the Interest Period
applicable to such Loan or Loans and the last day thereof.
<PAGE>
                                       17

         (c) The Administrative Agent shall promptly notify the Borrower by
telecopy of the Competitive Bid Rate and the principal amount of each
Competitive Loan in respect of which a Competitive Bid shall have been made and
the identity of the Lender that shall have made each bid.

     (d) The Borrower may, subject only to the provisions of this paragraph (d),
accept or reject any Competitive Bid. The Borrower shall notify the
Administrative Agent by telephone, confirmed by telecopy in the form of a
Competitive Bid Accept/Reject Letter, whether and to what extent it has decided
to accept or reject each Competitive Bid, (x) in the case of a Eurodollar
Competitive Borrowing, not later than 10:30 a.m., New York City time, three
Business Days before the date of the proposed Competitive Borrowing and (y) in
the case of a Fixed Rate Borrowing, not later than 10:30 a.m., New York City
time, on the proposed date of the Competitive Borrowing; provided, however, that
(i) the failure of the Borrower to give such notice shall be deemed to be a
rejection of each Competitive Bid, (ii) the Borrower shall not accept a
Competitive Bid made at a particular Competitive Bid Rate if the Borrower has
decided to reject a Competitive Bid made at a lower Competitive BidRate, (iii)
the aggregate amount of the Competitive Bids accepted by the Borrower shall not
exceed (but may be less than) the principal amount specified in the Competitive
Bid Request, (iv) if the Borrower shall accept a Competitive Bid or Bids made at
a particular Competitive Bid Rate but the amount of such Competitive Bid or Bids
would cause the total amount to be accepted by the Borrower to exceed the amount
specified in the Competitive Bid Request, then the Borrower shall accept a
portion of such Competitive Bid or Bids in an amount equal to the amount
specified in the Competitive Bid Request less the amount of all other
Competitive Bids so accepted, which acceptance, in the case of multiple
Competitive Bids at such Competitive Bid Rate, shall be made pro rata in
accordance with the amount of each such Bid and (v) except pursuant to clause
(iv) above, no Competitive Bid shall be accepted for a Competitive Loan unless
such Competitive Loan is in a minimum principal amount of $5,000,000 and an
integral multiple of $1,000,000; provided further, however, that if a
Competitive Loan must be in an amount less than $5,000,000 because of the
provisions of clause (iv) above, such Competitive Loan may be for a minimum of
$1,000,000 or any integral multiple thereof, and in calculating the pro rata
allocation of acceptances of portions of multiple Competitive Bids at a
particular Competitive Bid Rate pursuant to clause (iv) the amounts shall be
rounded to integral multiples of $1,000,000 in a manner determined by the
Borrower. A notice given by the Borrower pursuant to this paragraph (d) shall be
irrevocable.

         (e) The Administrative Agent shall promptly notify each bidding Lender
by telecopy whether or not its Competitive Bid has been accepted (and, if so, in
what amount and at what Competitive Bid Rate), and each successful bidder will
thereupon become bound, upon the terms and subject to the conditions hereof, to
make the Competitive Loan in respect of which its Competitive Bid has been
accepted.

         (f) If the Administrative Agent shall elect to submit a Competitive Bid
in its capacity as a Lender, it shall submit such Competitive Bid directly to
the Borrower at least one quarter of an hour earlier than the time by which the
other Lenders are required to submit their Competitive Bids to the
Administrative Agent pursuant to paragraph (b) above.

         SECTION 2.04. Borrowing Procedure. In order to request a Borrowing

apply), the Borrower shall hand deliver or telecopy to the Administrative Agent
a duly completed Borrowing Request (a) in the case of a Eurodollar Borrowing,

complies with the requirements of Section 2.02(c)); (iv) the amount of such
Borrowing; and (v) if such Borrowing is to be a Eurodollar Borrowing, the
Interest Period with respect thereto; provided, however, that, notwithstanding
any contrary specification in any Borrowing Request, each requested Borrowing
shall comply with the requirements set forth in Section 2.02. If no election as
to the Type of Borrowing is specified in any such notice, then the requested
Borrowing shall be an ABR Borrowing. If no Interest Period with respect to any
Eurodollar Borrowing is specified in any such notice, then the Borrower shall be
deemed to have selected an Interest Period of one month's duration. The
Administrative Agent shall promptly advise the Lenders of any notice given
pursuant to this Section 2.04 (and the contents thereof), and of each Lender's
portion of the requested Borrowing.

         SECTION 2.05. Evidence of Debt; Repayment of Loans. (a) The Borrower
hereby agrees that the outstanding principal balance of each Revolving Loan

         (c) The Administrative Agent shall maintain accounts in which it will
record (i) the amount of each Loan made hereunder, the Type thereof and the
Interest Period applicable thereto, (ii) the amount of any principal or interest
due and payable or to become due and payable from the Borrower to each Lender
hereunder and (iii) the amount of any sum received by the Administrative Agent
hereunder from the Borrower and each Lender's share thereof.

         (d) The entries made in the accounts maintained pursuant to paragraphs
(b) and (c) of this Section 2.05 shall be prima facie evidence of the existence
and amounts of the obligations therein recorded; provided, however, that the
failure of any Lender or the Administrative Agent to maintain such accounts or
any error therein shall not in any manner affect the obligations of the Borrower
to repay the Loans in accordance with their terms.
<PAGE>
                                       19

         (e) Notwithstanding any other provision of this Agreement, in the event
any Lender shall request and receive a promissory note payable to such Lender
and its registered assigns, the interests represented by such note shall at all
times (including after any assignment of all or part of such interests pursuant
to Section 9.04) be represented by one or more promissory notes payable to the
payee named therein or its registered assigns.

         SECTION 2.06. Fees. (a) The Borrower agrees to pay to each Lender,
through the Administrative Agent, on the last day of March, June, September and
December in each year, and on the date on which the Commitment of such Lender
shall be terminated as provided herein, a facility fee (a "Facility Fee") equal
to the Applicable Percentage per annum in effect from time to time on the
average daily amount of the Commitment of such Lender (whether used or unused)
during the preceding quarter (or shorter period commencing with the date hereof
or ending with the Maturity Date or the date on which the Commitment of such
Lender shall expire or be terminated). All Facility Fees shall be computed on
the basis of the actual number of days elapsed in a year of 360 days. The
Facility Fee due to each Lender shall commence to accrue on the date of this
Agreement and shall cease to accrue on the earlier of the Maturity Date and the
date on which the Commitment of such Lender shall be terminated as provided
herein.

         (b) The Borrower agrees to pay to each of the Agents or their
Affiliates, for their own account, the fees set forth in the Fee Letter at the
times and in the amounts specified therein (the "Agents' Fees").

         (c) All Fees shall be paid on the dates due, in immediately available
funds. Once paid, none of the Fees shall be refundable under any circumstances.

         SECTION 2.07. Interest on Loans. (a) Subject to the provisions of
Section 2.08, the Loans comprising each ABR Borrowing shall bear interest
(computed on the basis of the actual number of days elapsed over a year of 365
or 366 days, as the case may be, when the Alternate Base Rate is determined by
reference to the Prime Rate and over a year of 360 days at all other times) at a
rate per annum equal to the Alternate Base Rate.

         (b) Subject to the provisions of Section 2.08, the Loans comprising
each Eurodollar Borrowing shall bear interest (computed on the basis of the
actual number of days elapsed over a year of 360 days) at a rate per annum equal
to (i) in the case of each Revolving Loan, the LIBO Rate for the Interest Period
in effect for such Borrowing plus the Applicable Percentage in effect from time
to time and (ii) in the case of each Competitive Loan, the LIBO Rate for the
Interest Period in effect for such Borrowing plus the Margin offered by the
Lender making such Loan and accepted by the Borrower pursuant to Section 2.03.

         (c) Subject to the provisions of Section 2.08, each Fixed Rate Loan
shall bear interest (computed on the basis of the actual number of days elapsed
over a year of 360 days) at a rate per annum equal to the fixed rate of interest
offered by the Lender making such Loan and accepted by the Borrower pursuant to
Section 2.03.


<PAGE>
                                       20

        (d) Interest on each Loan shall be payable on the Interest Payment
Dates applicable to such Loan except as otherwise provided in this Agreement.
The applicable Alternate Base Rate or LIBO Rate for each Interest Period or day
within an Interest Period, as the case may be, shall be determined by the
Administrative Agent, and such determination shall be conclusive absent manifest
error.

         SECTION 2.08. Default Interest. If the Borrower shall default in the
payment of the principal of or interest on any Loan or any other amount becoming
due hereunder, by acceleration or otherwise, the Borrower shall on demand from
time to time pay interest, to the extent permitted by law, on such defaulted
amount to but excluding the date of actual payment (after as well as before
judgment) (a) in the case of overdue principal, at the rate otherwise applicable
to such Loan pursuant to Section 2.07 plus 2.00% per annum and (b) in all other
cases, at a rate per annum (computed on the basis of the actual number of days
elapsed over a year of 365 or 366 days, as the case may be, when determined by
reference to the Prime Rate and over a year of 360 days at all other times)
equal to the sum of the Alternate Base Rate plus 2.00%.

         SECTION 2.09. Alternate Rate of Interest. In the event, and on each
occasion, that on the day two Business Days prior to the commencement of any
Interest Period for a Eurodollar Borrowing the Administrative Agent shall have
determined that (a) Dollar deposits in the principal amounts of the Loans
comprising such Borrowing are not generally available in the London interbank
market, or (b) the rates at which such Dollar deposits are being offered will
not adequately and fairly reflect the cost to Lenders having Commitments
representing at least 20% of the Total Commitment of making or maintaining
Eurodollar Loans during such Interest Period, or (c) reasonable means do not
exist for ascertaining the LIBO Rate, the Administrative Agent shall, as soon as
practicable thereafter, give written or telecopy notice of such determination to
the Borrower and the Lenders. In the event of any such determination (other than
any such determination pursuant to clause (b) of the preceding sentence, to the
extent the circumstances giving rise to such determination would also give
Lenders the right to demand additional amounts pursuant to Section 2.14), until
the Administrative Agent shall have advised the Borrower and the Lenders that
the circumstances giving rise to such notice no longer exist, (i) any request by
the Borrower for a Eurodollar Revolving Credit Borrowing pursuant to Section
2.04 shall be deemed to be a request for an ABR Borrowing and (ii) any request
by the Borrower for a Eurodollar Competitive Borrowing pursuant to Section 2.03
shall be of no force and effect and shall be denied by the Administrative Agent.
Each determination by the Administrative Agent hereunder shall be conclusive
absent manifest error.

         SECTION 2.10.  Termination and Reduction of Commitments.  (a)  The 
Commitments shall automatically terminate on the Maturity Date.

         (b) Upon at least three Business Days' prior irrevocable written or
telecopy notice to the Administrative Agent, the Borrower may at any time in
whole permanently terminate, or from time to time in part permanently reduce,
the Commitments; provided, however, that (i) each partial reduction of the
Commitments shall be in an integral multiple of $1,000,000 and in a minimum
amount of $10,000,000 and (ii) the Total Commitment shall not be reduced to an
amount that is less than the sum of the Aggregate Revolving Credit Exposure and
the aggregate outstanding principal amount of the Competitive Loans at the time.
<PAGE>
                                       21

         (c) Each reduction in the Commitments hereunder shall be made ratably
among the Lenders in accordance with their respective Commitments. The Borrower
shall pay to the Administrative Agent for the account of the applicable Lenders,
on the date of each termination or reduction, the Facility Fees on the amount of
the Commitments so terminated or reduced accrued to but excluding the date of
such termination or reduction.

         SECTION 2.11. Conversion and Continuation of Revolving Credit
Borrowings. The Borrower shall have the right at any time upon prior irrevocable
notice to the Administrative Agent (a) not later than 10:00 a.m., New York City
time, on the day of conversion, to convert any Eurodollar Borrowing into an ABR
Borrowing, (b) not later than 10:00 a.m., New York City time, three Business
Days prior to conversion or continuation, to convert any ABR Borrowing into a
Eurodollar Borrowing or to continue any Eurodollar Borrowing as a Eurodollar
Borrowing for an additional Interest Period, and (c) not later than 10:00 a.m.,
New York City time, three Business Days prior to conversion, to convert the
Interest Period with respect to any Eurodollar Borrowing to another permissible
Interest Period, subject in each case to the following:

                  (i) each conversion or continuation shall be made pro rata
         among the Lenders in accordance with the respective principal amounts
         of the Loans comprising the converted or continued Borrowing;

                  (ii) if less than all the outstanding principal amount of any
         Borrowing shall be converted or continued, then each resulting
         Borrowing shall satisfy the limitations specified in Sections 2.02(a)
         and 2.02(b) regarding the principal amount and maximum number of
         Borrowings of the relevant Type;

                  (iii) each conversion shall be effected by each Lender by
         recording for the account of such Lender the new Loan of such Lender
         resulting from such conversion and reducing the Loan (or portion
         thereof) of such Lender being converted by an equivalent principal
         amount; accrued interest on any Eurodollar Loan (or portion thereof)
         being converted shall be paid by the Borrower at the time of
         conversion;

                  (iv) if any Eurodollar Borrowing is converted at a time other
         than the end of the Interest Period applicable thereto, the Borrower
         shall pay, upon demand, any amounts due to the Lenders pursuant to
         Section 2.16;

                  (v)  any portion of a Borrowing maturing or required to be
         repaid in less than one month may not be converted into or continued
         as a Eurodollar Borrowing; and

                  (vi) any portion of a Eurodollar Borrowing that cannot be
         converted into or contin ued as a Eurodollar Borrowing by reason of the
         immediately preceding clause shall be automatically converted at the
         end of the Interest Period in effect for such Borrowing into an ABR
         Borrowing.

                                       22

         Each notice pursuant to this Section 2.11 shall be irrevocable and
shall refer to this Agreement and specify (i) the identity and amount of the
Borrowing that the Borrower requests be converted or continued, (ii) whether
such Borrowing is to be converted into or continued as a Eurodollar Borrowing or
an ABR Borrowing, (iii) if such notice requests a conversion, the date of such
conversion (which shall be a Business Day) and (iv) if such Borrowing is to be
converted into or continued as a Eurodollar Borrowing, the Interest Period with
respect thereto (which may not end after the Maturity Date). If no Interest
Period is specified in any such notice with respect to any conversion into or
continuation as a Eurodollar Borrowing, the Borrower shall be deemed to have
selected an Interest Period of one month's duration. The Administrative Agent
shall advise the other Lenders of any notice given pursuant to this Section 2.11
and of each Lender's portion of any converted or continued Borrowing. If the
Borrower shall not have given notice in accordance with this Section 2.11 to
continue any Borrowing into a subsequent Interest Period (and shall not
otherwise have given notice in accordance with this Section 2.11 to convert such
Borrowing), such Borrowing shall, at the end of the Interest Period applicable
thereto (unless repaid pursuant to the terms hereof), automatically be continued
into a new Interest Period as an ABR Borrowing. The Borrower shall not have the
right to continue or convert the Interest Period with respect to any Competitive
Borrowing pursuant to this Section 2.11.

         SECTION 2.12.  Optional Prepayment.  (a)  The Borrower shall have the
right at any time and from time to time to prepay any Borrowing (other than a
Competitive Borrowing), in whole or in part, upon at least three Business Days'
prior written or telecopy notice (or telephone notice promptly confirmed by 
written or telecopy notice) to the Administrative Agent before 11:00 a.m., New
York City time; provided, however, that each partial prepayment shall be in an 
amount that is an integral multiple of $1,000,000 and not less than $10,000,000.
The Borrower shall not have the right to prepay any Competitive Borrowing.

         (b) In the event of any termination of the Commitments, the Borrower
shall repay or prepay all its outstanding Revolving Credit Borrowings on the
date of such termination. In the event of any partial reduction of the
Commitments, then (i) at or prior to the effective date of such reduction, the
Administrative Agent shall notify the Borrower and the Lenders of the Aggregate
Revolving Credit Exposure and (ii) if the Aggregate Revolving Credit Exposure
would exceed the available Total Commitment after giving effect to such
reduction, the Borrower shall, on the date of such reduction, repay or prepay
Revolving Credit Borrowings in an amount sufficient to eliminate such excess.

         (c) Each notice of prepayment shall specify the prepayment date and the
principal amount of each Borrowing (or portion thereof) to be prepaid, shall be
irrevocable and shall commit the Borrower to prepay such Borrowing by the amount
stated therein on the date stated therein. All prepayments under this Section
2.12 shall be subject to Section 2.16 but otherwise without premium or penalty.
All prepayments of Eurodollar Loans under this Section 2.12 shall be accompanied
by accrued interest on the principal amount being prepaid to the date of
payment.

         SECTION 2.13. Required Commitment Reductions and Prepayments. (a) If
prior to the second anniversary of the Closing Date the Borrower or any
Subsidiary shall complete any Asset Sale, then within three Business Days of the
receipt by the Borrower or any Subsidiary of any Net Cash Proceeds therefrom,
the Borrower shall on such date permanently reduce the Commitments and/or the
commitments under the 364-day Agreement and/or, after the consummation of the
Hughes Merger, the commitments under one or both of the Hughes Credit
Agreements, at the option of the Borrower, by an aggregate amount, which when
aggregated with all required commitment reductions made pursuant to Section
2.13(a) or (b) prior to such date, shall equal at least 75% of the aggregate Net
Cash Proceeds of such Asset Sale and all other Asset Sales and Debt Issuances
made prior to such date and, to the extent the outstanding Loans would exceed
the Total Commitment as so reduced, prepay any Revolving Loans then outstanding
on or prior to the effectiveness of such reduction by an amount sufficient to
eliminate such excess.

         (b) If prior to the second anniversary of the Closing Date the Borrower
or any Subsidiary shall complete any Debt Issuance, then within three Business
Days of the receipt by the Borrower or any Subsidiary of any Net Cash Proceeds
therefrom, the Borrower shall on such date permanently reduce the Commitments
and/or the commitments under the 364-day Agreement and/or, after the
consummation of the Hughes Merger, the commitments under one or both of the
Hughes Credit Agreements, at the option of the Borrower, by an aggregate amount,
which when aggregated with all required commitment reductions made pursuant to
Section 2.13(a) or (b) prior to such date, shall equal at least 75% of the
aggregate Net Cash Proceeds of such Debt Issuance and all other Debt Issuances
and Asset Sales made prior to such date and, to the extent the outstanding Loans
would exceed the Total Commitment as so reduced, prepay any Revolving Loans then
outstanding on or prior to the effectiveness of such reduction by an amount
sufficient to eliminate such excess.

         (c) In the event any prepayment required by Section 2.13(a) or (b) with
respect to any Revolving Loan would become due on a date that is not the last
day of the relevant Interest Period therefor and as a result thereof the
Borrower would incur liabilities under Section 2.16, then (i) if the last day of
the relevant Interest Period for such Loan would occur within 180 days of the
date on which such prepayment is otherwise due, and (ii) no Default or Event of
Default shall have occurred and be continuing, such prepayment may be made at
the Borrower's election on the last day of the relevant Interest Period for such
Loan and, pending such prepayment, the Borrower shall deposit such Net Cash
Proceeds with the Administrative Agent which shall hold such Net Cash Proceeds
for the benefit of the Lenders, in an interest bearing account, until such time
as such proceeds can be applied towards payment of the Loans in accordance with
the provisions of this Agreement without resulting in any liability to the
Borrower under Section 2.16. Until such Loans are so prepaid they shall 
continue to accrue interest as provided hereunder, provided that all interest
which may accrue on any amounts so held in escrow shall be delivered by the
Administrative Agent to the Borrower following prepayment of the principal of
and accrued interest on such Loans.

         SECTION 2.14. Reserve Requirements; Change in Circumstances. (a)
Notwithstanding any other provision of this Agreement, if after the date of this
Agreement any change in applicable law or regulation or in the interpretation or
administration thereof by any Governmental Authority charged with the
interpretation or administration thereof (whether or not having the force of
law) shall impose, modify or deem applicable any reserve, special deposit or
similar requirement against assets of, deposits with or for the account of or
credit extended by any Lender or shall impose on such Lender or the London
interbank market any other condition affecting this Agreement or Eurodollar
Loans or Fixed Rate Loans made by such Lender, and the result of any of the
foregoing shall be to increase the cost to such Lender of making or maintaining
any Eurodollar Loan or Fixed Rate Loan, or to reduce the amount of any sum
received or receivable by such Lender hereunder (whether of principal, interest
or otherwise) by an amount deemed by such Lender to be material, then the
Borrower will pay to such Lender upon demand such additional amount or amounts
as will compensate such Lender for such additional costs incurred or reduction
suffered.

         (b) If any Lender shall have determined that the adoption after the
date hereof of any law, rule, regulation, agreement or guideline regarding
capital adequacy, or any change after the date hereof in any such law, rule,
regulation, agreement or guideline (whether such law, rule, regulation,
agreement or guideline has been adopted) or in the interpretation or
administration thereof by any Governmental Authority charged with the
interpretation or administration thereof, or compliance by any Lender (or any
lending office of such Lender) or any Lender's holding company with any request
or directive regarding capital adequacy (whether or not having the force of law)
of any Governmental Authority has or would have the effect of reducing the rate
of return on such Lender's capital or on the capital of such Lender's holding
company, if any, as a consequence of this Agreement or the Loans made by such
Lender pursuant hereto to a level below that which such Lender or such Lender's
holding company could have achieved but for such applicability, adoption, change
or compliance (taking into consideration such Lender's policies and the policies
of such Lender's holding company with respect to capital adequacy) by an amount
deemed by such Lender to be material, then from time to time the Borrower shall
pay to such Lender such additional amount or amounts as will compensate such
Lender or such Lender's holding company for any such reduction suffered.

         (c) A certificate of a Lender setting forth the amount or amounts
necessary to compensate such Lender or its holding company (including the
calculation thereof) as specified in paragraph (a) or (b) above shall be
delivered to the Borrower and shall be conclusive absent manifest error. The
Borrower shall pay such Lender the amount shown as due on any such certificate
delivered by it within 10 days after its receipt of the same.

         (d) Failure or delay on the part of any Lender to demand compensation
for any increased costs or reduction in amounts received or receivable or
reduction in return on capital shall not constitute a waiver of such Lender's
right to demand such compensation. The protection of this Section shall be
available to each Lender regardless of any possible contention of the invalidity
or inapplicability of the law, rule, regulation, agreement, guideline or other
change or condition that shall have occurred or been imposed. Notwithstanding
any other provision of this Section, no Lender shall be entitled to demand
compensation hereunder in respect of any Competitive Loan if it shall have been
aware of the event or circumstance giving rise to such demand at the time it
submitted the Competitive Bid pursuant to which such Loan was made.

                                       25

         SECTION 2.15. Change in Legality. (a) Notwithstanding any other
provision of this Agreement, if, after the date hereof, any change in any law or
regulation or in the interpretation thereof by any Governmental Authority
charged with the administration or interpretation thereof shall make it unlawful
for any Lender to make or maintain any Eurodollar Loan or to give effect to its
obligations as contemplated hereby with respect to any Eurodollar Loan, then, by
written notice to the Borrower and to the Administrative Agent:

                  (i) such Lender may declare that Eurodollar Loans will not
         thereafter (for the duration of such unlawfulness) be made by such
         Lender hereunder (or be continued for additional Interest Periods and
         ABR Loans will not thereafter (for such duration) be converted into
         Eurodollar Loans), whereupon such Lender shall not submit a Competitive
         Bid in response to a request for a Eurodollar Competitive Loan and any
         request for a Eurodollar Borrowing (or to convert an ABR Borrowing to a
         Eurodollar Borrowing or to continue a Eurodollar Borrowing for an
         additional Interest Period) shall, as to such Lender only, be deemed a
         request for an ABR Loan unless such declaration shall be subsequently
         withdrawn (or a request to continue an ABR Loan as such for an
         additional Interest Period or to convert a Eurodollar Loan into an ABR
         Loan, as the case may be); and

                  (ii) such Lender may require that all outstanding Eurodollar
         Loans made by it be converted to ABR Loans, in which event all such
         Eurodollar Loans shall be automatically converted to ABR Loans as of
         the effective date of such notice as provided in paragraph (b) below.

In the event any Lender shall exercise its rights under (i) or (ii) above, all
payments and prepayments of principal that would otherwise have been applied to
repay the Eurodollar Loans that would have been made by such Lender or the
converted Eurodollar Loans of such Lender shall instead be applied to repay the
ABR Loans made by such Lender in lieu of, or resulting from the conversion of,
such Eurodollar Loans.

         (b) For purposes of this Section 2.15, a notice to the Borrower by any
Lender shall be effective as to each Eurodollar Loan made by such Lender, if
lawful, on the last day of the Interest Period currently applicable to such
Eurodollar Loan; in all other cases such notice shall be effective on the date
of receipt by the Borrower.

         SECTION 2.16. Indemnity. The Borrower shall indemnify each Lender
against any loss or expense that such Lender may sustain or incur as a
consequence of any event, other than a default by such Lender in the performance
of its obligations hereunder, that results in (i) such Lender receiving or being
deemed to receive any amount on account of the principal of any Fixed Rate Loan
or Eurodollar Loan prior to the end of the Interest Period in effect therefor,
(ii) the conversion of any Eurodollar Loan to an ABR Loan, or the conversion of
the Interest Period with respect to any Eurodollar Loan, in each case prior to
the end of the Interest Period in effect therefor or (iii) any Fixed Rate Loan
or Eurodollar Loan to be made by such Lender (including any Eurodollar Loan to
be made pursuant to a conversion or continuation under Section 2.11) not being
made after notice of such Loan shall have been given by the Borrower hereunder
(any of the events referred to in this sentence being called a "Breakage
Event"). In the case of any Breakage Event, such loss shall include an amount
equal to the excess, as reasonably determined by such Lender, of (i) its cost of
obtaining funds for the Eurodollar Loan or Fixed Rate Loan that is the subject
of such Breakage Event for the period from the date of such Breakage Event to
<PAGE>
                                       26

the last day of the Interest Period in effect (or that would have been in
effect) for such Loan over (ii) the amount of interest likely to be realized by
such Lender in redeploying the funds released or not utilized by reason of such
Breakage Event for such period. A certificate of any Lender setting forth any
amount or amounts that such Lender is entitled to receive pursuant to this
Section 2.16 shall be delivered to the Borrower and shall be conclusive absent
manifest error.

         SECTION 2.17. Pro Rata Treatment. Except as provided in the two
succeeding sentences with respect to Competitive Borrowings and as required
under Section 2.15, each Borrowing, each payment or prepayment of principal of
any Borrowing, each payment of interest on the Loans, each payment of the
Facility Fees, each reduction of the Commitments and each continuation or
conversion of any Borrowing to a Borrowing of any Type shall be allocated pro
rata among the Lenders in accordance with their respective Commitments (or, if
such Commitments shall have expired or been terminated, in accordance with the
respective principal amounts of their outstanding Loans). Each payment of
principal of any Competitive Borrowing shall be allocated pro rata among the
Lenders participating in such Borrowing in accordance with the respective
principal amounts of their outstanding Competitive Loans comprising such
Borrowing. Each payment of interest on any Competitive Borrowing shall be 
allocated pro rata among the Lenders participating in such Borrowing in
accordance with the respective amounts of accrued and unpaid interest on their
outstanding Competitive Loans comprising such Borrowing. For purposes of
determining the available Commitments of the Lenders at any time, each
outstanding Competitive Borrowing shall be deemed to have utilized the
Commitments of the Lenders (including those Lenders that shall not have made
Loans as part of such Competitive Borrowing) pro rata in accordance with such
respective Commitments. Each Lender agrees that in computing such Lender's
portion of any Borrowing to be made hereunder, the Administrative Agent may, in
its discretion, round each Lender's percentage of such Borrowing to the next
higher or lower whole Dollar amount.

         SECTION 2.18. Sharing of Setoffs. Each Lender agrees that if it shall,
through the exercise of a right of banker's lien, setoff or counterclaim against
the Borrower, or pursuant to a secured claim under Section 506 of Title 11 of
the United States Code or other security or interest arising from, or in lieu
of, such secured claim, received by such Lender under any applicable bankruptcy,
insolvency or other similar law or otherwise, or by any other means, obtain
payment (voluntary or involuntary) in respect of any Revolving Loan or Loans as
a result of which the unpaid principal portion of its Revolving Loans shall be
proportionately less than the unpaid principal portion of the Revolving Loans of
any other Lender, it shall be deemed simultaneously to have purchased from such
other Lender at face value, and shall promptly pay to such other Lender the
purchase price for, a participation in the Revolving Loans of such other Lender,
so that the aggregate unpaid principal amount of the Revolving Loans and
participations in Revolving Loans held by each Lender shall be in the same
proportion to the aggregate unpaid principal amount of all Revolving Loans then
outstanding as the principal amount of its Revolving Loans prior to such
exercise of banker's lien, setoff or counterclaim or other event was to the
principal amount of all Revolving Loans outstanding prior to such exercise of
banker's lien, setoff or counterclaim or other event; provided, however, that,
if any such purchase or purchases or adjustments shall be made pursuant to this
Section and the payment giving rise thereto shall thereafter be recovered, such
purchase or purchases or adjustments shall be rescinded to the extent of such
<PAGE>
                                       27

recovery and the purchase price or prices or adjustment restored without
interest. The Borrower expressly consents to the foregoing arrangements and
agrees that any Lender holding a participation in a Revolving Loan deemed to
have been so purchased may exercise any and all rights of banker's lien, setoff
or counterclaim with respect to any and all moneys owing by the Borrower to such
Lender by reason thereof as fully as if such Lender had made a Revolving Loan
directly to the Borrower in the amount of such participation.

         SECTION 2.19. Payments. (a) The Borrower shall make each payment
(including principal of or interest on any Borrowing or any Fees or other
amounts) hereunder not later than 12:00 (noon), New York City time, on the date
when due in immediately available Dollars, without defense, setoff or
counterclaim. Each such payment shall be made to the Administrative Agent at its
offices at 270 Park Avenue, New York, New York.

         (b) Whenever any payment (including principal of or interest on any
Borrowing or any Fees or other amounts) hereunder shall become due, or otherwise
would occur, on a day that is not a Business Day, such payment may be made on
the next succeeding Business Day, and such extension of time shall in such case
be included in the computation of interest or Fees, if applicable.

         SECTION 2.20. Taxes. (a) Any and all payments by the Borrower hereunder
shall be made, in accordance with Section 2.19, free and clear of and without
deduction for any and all current or future taxes, levies, imposts, deductions,
charges or withholdings, and all liabilities with respect thereto, excluding (i)
income taxes imposed on the net income of the Administrative Agent or any Lender
(or any transferee or assignee thereof, including a participation holder (any
such entity a "Transferee")) and (ii) franchise taxes imposed on the net income
of the Administrative Agent or any Lender (or Transferee), in each case by the
jurisdiction under the laws of which the Administrative Agent or such Lender (or
Transferee) is organized or any political subdivision thereof (all such
nonexcluded taxes, levies, imposts, deductions, charges, withholdings and
liabilities, collectively or individually, being called "Taxes"). If the
Borrower shall be required to deduct any Taxes from or in respect of any sum
payable hereunder to the Administrative Agent or any Lender (or any Transferee),
(i) the sum payable shall be increased by the amount (an "additional amount")
necessary so that after making all required deductions (including deductions
applicable to additional sums payable under this Section 2.20) the
Administrative Agent or such Lender (or Transferee), as the case may be, shall
receive an amount equal to the sum it would have received had no such deductions
been made, (ii) the Borrower shall make such deductions and (iii) the Borrower 
shall pay the full amount deducted to the relevant Governmental Authority in 
accordance with applicable law.

         (b) In addition, the Borrower agrees to pay to the relevant
Governmental Authority in accordance with applicable law any current or future
stamp or documentary taxes or any other excise or property taxes, charges or
similar levies that arise from any payment made hereunder or from the execution,
delivery or registration of, or otherwise with respect to, this Agreement
("Other Taxes").
<PAGE>
                                       28

         (c) The Borrower will indemnify the Administrative Agent and each
Lender (or Transferee) for the full amount of Taxes and Other Taxes paid by the
Administrative Agent or such Lender (or Transferee), as the case may be, and any
liability (including penalties, interest and expenses (including reasonable
attorney's fees and expenses)) arising therefrom or with respect thereto,
whether or not such Taxes or Other Taxes were correctly or legally asserted by
the relevant Governmental Authority. A certificate as to the amount of such
payment or liability prepared by the Administrative Agent or a Lender (or
Transferee), or the Administrative Agent on its behalf, absent manifest error,
shall be final, conclusive and binding for all purposes. Such indemnification
shall be made within 30 days after the date the Administrative Agent or any
Lender (or Transferee), as the case may be, makes written demand therefor.

         (d) If the Administrative Agent or a Lender (or Transferee) receives a
refund in respect of any Taxes or Other Taxes as to which it has been
indemnified by the Borrower or with respect to which the Borrower has paid
additional amounts pursuant to this Section 2.20, it shall within 30 days from
the date of such receipt pay over such refund to the Borrower (but only to the
extent of indemnity payments made, or additional amounts paid, by the Borrower
under this Section 2.20 with respect to the Taxes or Other Taxes giving rise to
such refund), net of all out-of-pocket expenses of the Administrative Agent or
such Lender (or Transferee) and without interest (other than interest paid by
the relevant Governmental Authority with respect to such refund); provided,
however, that the Borrower, upon the request of the Administrative Agent or such
Lender (or Transferee), shall repay the amount paid over to the Borrower (plus
penalties, interest or other charges) to the Administrative Agent or such Lender
(or Transferee) in the event the Administrative Agent or such Lender (or
Transferee) is required to repay such refund to such Governmental Authority.

         (e) As soon as practicable after the date of any payment of Taxes or
Other Taxes by the Borrower to the relevant Governmental Authority, the Borrower
will deliver to the Administrative Agent, at its address referred to in Section
9.01, the original or a certified copy of a receipt issued by such Governmental
Authority evidencing payment thereof.

         (f) Without prejudice to the survival of any other agreement contained
herein, the agreements and obligations contained in this Section 2.20 shall
survive the payment in full of the principal of and interest on all Loans made
hereunder.

         (g) Each Lender (or Transferee) that is organized under the laws of a
jurisdiction other than the United States, any State thereof or the District of
Columbia (a "Non-U.S. Lender") shall deliver to each of the Borrower and the
Administrative Agent two copies of either United States Internal Revenue Service
Form 1001 or Form 4224, or, in the case of a Non-U.S. Lender claiming exemption
from U.S. Federal withholding tax under Section 871(h) or 881(c) of the Code
with respect to payments of "portfolio interest", a Form W-8, or any subsequent
versions thereof or successors thereto (and, if such Non-U.S. Lender delivers a
Form W-8, a certificate representing that such Non-U.S. Lender is not a bank for
purposes of Section 881(c) of the Code, is not a 10-percent shareholder (within
the meaning of Section 871(h)(3)(B) of the Code) of the Borrower and is not a
controlled foreign corporation related to the Borrower (within the meaning of
Section 864(d)(4) of the Code)), properly completed and duly executed by such
<PAGE>
                                       29

Non-U.S. Lender claiming complete exemption from, or reduced rate of, U.S.
Federal withholding tax on payments by the Borrower under this Agreement. Such
forms shall be delivered by each Non-U.S. Lender on or before the date it
becomes a party to this Agreement (or, in the case of a Transferee that is a 
participation holder, on or before the date such participation holder becomes a
Transferee hereunder) and on or before the date, if any, such Non-U.S.
Lender changes its applicable lending office by designating a different lending
office (a "New Lending Office"). In addition, each Non-U.S. Lender shall deliver
such forms promptly upon the obsolescence or invalidity of any form previously
delivered by such Non-U.S. Lender. Notwithstanding any other provision of this
Section 2.20(g), a Non-U.S. Lender shall not be required to deliver any form
pursuant to this Section 2.20(g) that such Non-U.S. Lender is not legally able
to deliver.

        (h) The Borrower shall not be required to indemnify any Non-U.S. Lender
or to pay any additional amounts to any Non-U.S. Lender, in respect of United
States Federal withholding tax pursuant to paragraph (a) or (c) above to the
extent that (i) the obligation to withhold amounts with respect to United States
Federal withholding tax existed on the date such Non-U.S. Lender became a party
to this Agreement (or, in the case of a Transferee that is a participation
holder, on the date such participation holder became a Transferee hereunder) or,
with respect to payments to a New Lending Office, the date such Non-U.S. Lender
designated such New Lending Office with respect to a Loan; provided, however,
that this paragraph (h) shall not apply (x) to any Transferee or New Lending
Office that becomes a Transferee or New Lending Office as a result of an
assignment, participation, transfer or designation made at the request of the
Borrower and (y) to the extent the indemnity payment or additional amounts any
Transferee, or any Lender (or Transferee), acting through a New Lending Office,
would be entitled to receive (without regard to this paragraph (h)) do not
exceed the indemnity payment or additional amounts that the person making the
assignment, participation or transfer to such Transferee, or Lender (or
Transferee) making the designation of such New Lending Office, would have been
entitled to receive in the absence of such assignment, participation, transfer
or designation or (ii) the obligation to pay such additional amounts would not
have arisen but for a failure by such Non-U.S. Lender to comply with the
provisions of paragraph (g) above.

         (i) Nothing contained in this Section 2.20 shall require any Lender (or
any Transferee) or the Administrative Agent to make available any of its tax
returns (or any other information that it deems to be confidential or
proprietary).

         SECTION 2.21. Assignment of Commitments Under Certain Circumstances;
Duty to Mitigate. (a) In the event (i) any Lender delivers a certificate
requesting compensation pursuant to Section 2.14, (ii) any Lender delivers a
notice described in Section 2.15 or (iii) the Borrower is required to pay any
additional amount to any Lender or any Governmental Authority on account of any
Lender pursuant to Section 2.20, the Borrower may, at its sole expense and
effort, upon notice to such Lender and the Administrative Agent, require such
Lender to transfer and assign, without recourse (in accordance with and subject
to the restrictions contained in Section 9.04), all of its interests, rights and
obligations under this Agreement to an assignee which shall assume such assigned
obligations (which assignee may be another Lender, if a Lender accepts such
<PAGE>
                                       30

assignment); provided that (x) such assignment shall not conflict with any law,
rule or regulation or order of any court or other Governmental Authority having
jurisdiction, (y) the Borrower shall have received the prior written consent of
the Administrative Agent, which consent shall not unreasonably be withheld, and
(z) the Borrower or such assignee shall have paid to the affected Lender in
immediately available funds an amount equal to the sum of the principal of and
interest accrued to the date of such payment on the outstanding Loans of such
Lender plus all Fees and other amounts accrued for the account of such Lender
hereunder (including any amounts under Section 2.14 and Section 2.16); provided
further that if prior to any such transfer and assignment the circumstances or
event that resulted in such Lender's claim for compensation under Section 2.14
or notice under Section 2.15 or the amounts paid pursuant to Section 2.20, as
the case may be, cease to cause such Lender to suffer increased costs or
reductions in amounts received or receivable or reduction in return on capital,
or cease to have the consequences specified in Section 2.15, or cease to result
in amounts being payable under Section 2.20, as the case may be (including as a
result of any action taken by such Lender pursuant to paragraph (b) below), or
if such Lender shall waive its right to claim further compensation under Section
2.14 in respect of such circumstances or event or shall withdraw its notice
under Section 2.15 or shall waive its right to further payments under Section 
2.20 in respect of such circumstances or event, as the case may be, then such
Lender shall not thereafter be required to make any such transfer and assignment
hereunder.

         (b) If (i) any Lender shall request compensation under Section 2.14,
(ii) any Lender delivers a notice described in Section 2.15 or (iii) the
Borrower is required to pay any additional amount to any Lender or any
Governmental Authority on account of any Lender, pursuant to Section 2.20, then,
such Lender shall use reasonable efforts (which shall not require such Lender to
incur an unreimbursed loss or unreimbursed cost or expense or otherwise take any
action inconsistent with its internal policies or legal or regulatory
restrictions or suffer any disadvantage or burden deemed by it to be
significant) (x) to file any certificate or document reasonably requested in
writing by the Borrower or (y) to assign its rights and delegate and transfer
its obligations hereunder to another of its offices, branches or affiliates, if
such filing or assignment would reduce its claims for compensation under Section
2.14 or enable it to withdraw its notice pursuant to Section 2.15 or would
reduce amounts payable pursuant to Section 2.20, as the case may be, in the
future. The Borrower hereby agrees to pay all reasonable costs and expenses
incurred by any Lender in connection with any such filing, assignment,
delegation and transfer.

                                   ARTICLE III

                         Representations and Warranties

         The Borrower represents and warrants to the Administrative Agent and
each of the Lenders that:
<PAGE>
                                       31

         SECTION 3.01. Organization; Powers. The Borrower and each of the
Significant Subsidiaries (a) is a corporation duly organized, validly existing
and in good standing under the laws of the jurisdiction of its organization, (b)
has all requisite power and authority to own its property and assets and to
carry on its business as now conducted and as proposed to be conducted and (c)
is qualified to do business in, and is in good standing in, every jurisdiction
where such qualification is required, except where the failure so to qualify
could not reasonably be expected to result in a Material Adverse Effect. The
Borrower has the corporate power and authority to execute, deliver and perform
its obligations under this Agreement and to borrow hereunder. Schedule 3.01 sets
forth each Significant Subsidiary of the Borrower in existence on the Closing
Date.

         SECTION 3.02. Authorization. The execution, delivery and performance by
the Borrower of this Agreement and the borrowings hereunder (collectively, the
"Transactions") (a) have been duly authorized by all requisite corporate and, if
required, stockholder action and (b) will not (i) violate (A) any provision of
law, statute, rule or regulation, or of the certificate or articles of
incorporation or other constitutive documents or by-laws of the Borrower or any
Significant Subsidiary, (B) any order of any Governmental Authority or (C) any
material provision of any material indenture, agreement or other instrument to
which the Borrower or any Significant Subsidiary is a party or by which any of
them or any of their property is or may be bound, (ii) be in material conflict
with, result in a material breach of or constitute (alone or with notice or
lapse of time or both) a material default under, or give rise to any right to
accelerate or to require the prepayment, repurchase or redemption of any
obligation under any such material indenture, agreement or other instrument or
(iii) result in the creation or imposition of any Lien upon or with respect to
any property or assets now owned or hereafter acquired by the Borrower or any
Significant Subsidiary.

         SECTION 3.03. Enforceability. This Agreement has been duly executed and
delivered by the Borrower and constitutes a legal, valid and binding obligation
of the Borrower enforceable against the Borrower in accordance with its terms.

         SECTION 3.04. Governmental Approvals. No action, consent or approval
of, registration or filing with or any other action by any Governmental
Authority is or will be required in connection with the Transactions, except
those which have been made or obtained.

furnished to the Lenders its consolidated balance sheet, statement of income and
statement of cash flows as of and for the fiscal year ended December 31, 1996,
audited by and accompanied by the opinion of Coopers & Lybrand, independent
public accountants. Such financial statements present fairly the financial
condition and results of operations of the Borrower and its consolidated
Subsidiaries as of such date and for such period. Such balance sheet and the
notes thereto disclose all material liabilities, direct or contingent, of the
Borrower and its consolidated Subsidiaries as of the date thereof. Such
financial statements were prepared in accordance with GAAP applied on a
consistent basis.
<PAGE>
                                       32

         (b) The Borrower has heretofore delivered to the Lenders its unaudited
pro forma consolidated financial statements as of December 31, 1996, prepared
giving effect to the TI Acquisition as if it had occurred on such date. Such pro
forma financial statements have been prepared in good faith by the Borrower,
based on the assumptions used to prepare the pro forma financial information
contained in the Confidential Information Memorandum (which assumptions are
believed by the Borrower on the date hereof to be reasonable), are based on the
best information available to the Borrower as of the date of delivery thereof,
accurately reflect all adjustments required to be made to give effect to the TI
Acquisition and present fairly on a pro forma basis the estimated consolidated
financial position of the Borrower and its consolidated Subsidiaries as of
December 31, 1996, assuming that the TI Acquisition had actually occurred at
January 1, 1996.

         SECTION 3.06. No Material Adverse Change. There has been no material
adverse change in the business, assets, operations or condition, financial or
otherwise, of the Borrower and the Subsidiaries, taken as a whole, since
December 31, 1996.

         SECTION 3.07. Litigation; Compliance with Laws. (a) Except as set forth
on Schedule 3.07, there are not any actions, suits or proceedings at law or in
equity or by or before any Governmental Authority now pending or, to the
knowledge of the Borrower, threatened against or affecting the Borrower or any
Subsidiary or any business, property or rights of any such person (i) that
involve this Agreement or the Transactions or (ii) as to which there is a
reasonable possibility of an adverse determination and that, if adversely
determined, could reasonably be expected, individually or in the aggregate, to
result in a Material Adverse Effect. Except as set forth on Schedule 3.07, to
the knowledge of the Borrower, on the Closing Date there are not any actions,
suits or proceedings at law or in equity or by or before any Governmental
Authority now pending or threatened against or affecting the defense business of
TI or any business, property or rights relating thereto (i) that involve this
Agreement or the Transactions or (ii) as to which there is a reasonable
possibility of an adverse determination and that, if adversely determined, could
reasonably be expected, individually or in the aggregate, to result in a
Material Adverse Effect.

         (b) None of the Borrower or any of the Subsidiaries or any of their
respective material properties or assets is in violation of, nor will the
continued operation of their material properties and assets as currently
conducted violate, any law, rule or regulation, or is in default with respect to
any judgment, writ, injunction, decree or order of any Governmental Authority
(including any of the foregoing relating to the environment), where such
violation or default could reasonably be expected to result in a Material
Adverse Effect.

     SECTION 3.08. Federal Reserve Regulations. (a) Neither the Borrower nor any
of the Subsidiaries is engaged principally, or as one of its important
activities, in the business of extending credit for the purpose of buying or
carrying Margin Stock.
<PAGE>
                                       33

         (b) No part of the proceeds of any Loan will be used, whether directly
or indirectly, and whether immediately, incidentally or ultimately for any
purpose that entails a violation of, or that is inconsistent with, the
provisions of the Regulations of the Board, including Regulation G, U or X.
Margin Stocks do not constitute 25% or more of the fair market value of the
assets of the Borrower and the Subsidiaries subject to the restrictions of
Section 6.01.

     SECTION 3.09. Investment Company Act; Public Utility Holding Company Act.
Neither the Borrower nor any Subsidiary is (a) an "investment company" as
defined in, or subject to regulation under, the Investment Company Act of 1940
or (b) a "holding company" as defined in, or subject to regulation under, the
Public Utility Holding Company Act of 1935.
 
        SECTION 3.10. Tax Returns. Each of the Borrower and the Subsidiaries
has filed or caused to be filed all Federal and all material state, local and
foreign tax returns or materials required to have been filed by it and has paid
or caused to be paid all taxes shown to be due and payable by it on such returns
and all assessments received by it, except taxes that are being contested in
good faith by appropriate proceedings and for which the Borrower or such
Subsidiaries, as applicable, shall have set aside on its books adequate reserves
in accordance with GAAP.

         SECTION 3.11. No Material Misstatements. None of (a) the information
contained in the Confidential Information Memorandum and relating to the
Borrower and its Subsidiaries, (b) to the best knowledge of the Borrower, the
information contained in the Confidential Memorandum and relating to TI or the
assets and businesses to be acquired in the TI Acquisition or (c) any other
information, report, financial statement, exhibit or schedule furnished in
writing by or on behalf of the Borrower to the Administrative Agent or any
Lender in connection with the negotiation of this Agreement or included herein
or delivered pursuant hereto contained, contains or will contain any material
misstatement of fact or omitted, omits or will omit to state any material fact
necessary to make the statements therein, in the light of the circumstances
under which they were, are or will be made, not misleading; provided that to the
extent any such information, report, financial statement, exhibit or schedule
was based upon or constitutes a forecast or projection, the Borrower represents
only that it acted in good faith and utilized reasonable assumptions and due
care in the preparation of such information, report, financial statement,
exhibit or schedule.

         SECTION 3.12. Employee Benefit Plans. Each of the Borrower and its
ERISA Affiliates is in compliance in all material respects with the applicable
provisions of ERISA and the Code and the regulations and published
interpretations thereunder. No ERISA Event has occurred or is reasonably
expected to occur that, when taken together with all other such ERISA Events,
could reasonably be expected to result in a Material Adverse Effect. The present
value of all benefit liabilities under each Plan (based on those assumptions
used to fund such Plan) did not, as of the last annual valuation date applicable
thereto before the Closing Date, exceed the fair market value of the assets of
such Plan, and the present value of all benefit liabilities of all underfunded
Plans (based on those assumptions used to fund each such Plan) did not, as of
the last annual valuation dates applicable thereto before the Closing Date,
exceed the fair market value of the assets of all such underfunded Plans.

         The Borrower covenants and agrees with each Lender that so long as this

shall secure only those obligations which they secure on the date hereof;

     (b) any Lien existing on any property or asset prior to the acquisition

                                  ARTICLE VIII

                            The Administrative Agent

         In order to expedite the transactions contemplated by this Agreement,
The Chase Manhattan Bank is hereby appointed to act as Administrative Agent on
behalf of the Lenders. Each of the Lenders and each assignee of any such Lender
hereby irrevocably authorizes the Administrative Agent to take such actions on
behalf of such Lender or assignee and to exercise such powers as are
specifically delegated to the Administrative Agent by the terms and provisions
hereof, together with such actions and powers as are reasonably incidental
thereto. The Administrative Agent is hereby expressly authorized by the Lenders,
without hereby limiting any implied authority, (a) to receive on behalf of the
Lenders all payments of principal of and interest on the Loans and all other
amounts due to the Lenders hereunder, and promptly to distribute to each Lender
its proper share of each payment so received; (b) to give notice on behalf of
each of the Lenders to the Borrower of any Event of Default specified in this 
Agreement of which the Administrative Agent has actual knowledge acquired in 
connection with its agency hereunder; and (c) to distribute to each Lender 
copies of all notices, financial statements and other materials delivered by 
the Borrower pursuant to this Agreement as received by the Administrative Agent.

         Neither the Administrative Agent nor any of its directors, officers,
employees or agents shall be liable as such for any action taken or omitted by
any of them except for its or his own gross negligence or wilful misconduct, or
be responsible for any statement, warranty or representation herein or the
contents of any document delivered in connection herewith, or be required to
ascertain or to make any inquiry concerning the performance or observance by the
Borrower of any of the terms, conditions, covenants or agreements contained in
this Agreement. The Administrative Agent shall not be responsible to the Lenders
for the due execution, genuineness, validity, enforceability or effectiveness of
this Agreement or any other instruments or agreements. The Administrative Agent
shall in all cases be fully protected in acting, or refraining from acting, in
accordance with written instructions signed by the Required Lenders (or, when
expressly required hereunder, all the Lenders) and, except as otherwise
specifically provided herein, such instructions and any action or inaction
pursuant thereto shall be binding on all the Lenders. The Administrative Agent
shall, in the absence of knowledge to the contrary, be entitled to rely on any
instrument or document believed by it in good faith to be genuine and correct
and to have been signed or sent by the proper person or persons. Neither the
Administrative Agent nor any of its directors, officers, employees or agents
shall have any responsibility to the Borrower on account of the failure of or
delay in performance or breach by any Lender of any of its obligations hereunder
or to any Lender on account of the failure of or delay in performance or breach
by any other Lender or the Borrower of any of their respective obligations
hereunder or in connection herewith. The Administrative Agent may execute any
and all duties here under by or through agents or employees and shall be
entitled to rely upon the advice of legal counsel selected by it with respect to
all matters arising hereunder and shall not be liable for any action taken or
suffered in good faith by it in accordance with the advice of such counsel.

         The Lenders hereby acknowledge that the Administrative Agent shall be
under no duty to take any discretionary action permitted to be taken by it
pursuant to the provisions of this Agreement unless it shall be requested in
writing to do so by the Required Lenders.

                                       45

         Subject to the appointment and acceptance of a successor Administrative
Agent as provided below, the Administrative Agent may resign at any time by
notifying the Lenders and the Borrower. Upon any such resignation, the Required
Lenders shall have the right, with the consent of the Borrower (which consent
shall not be unreasonably withheld), to appoint a successor. If no successor
shall have been so appointed by the Required Lenders and shall have accepted
such appointment within 30 days after the retiring Administrative Agent gives
notice of its resignation, then the retiring Administrative Agent may, on behalf
of the Lenders, appoint a successor Administrative Agent which shall be a bank
with an office in New York, New York, having a combined capital and surplus of
at least $500,000,000 or an Affiliate of any such bank. Upon the acceptance of
any appointment as Administrative Agent hereunder by a successor bank, such
successor shall succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Administrative Agent and the retiring
Administrative Agent shall be discharged from its duties and obligations
hereunder. After the Administrative Agent's resignation hereunder, the
provisions of this Article and Section 9.05 shall continue in effect for its
benefit in respect of any actions taken or omitted to be taken by it while it
was acting as Administrative Agent.

         With respect to the Loans made by it hereunder, the Administrative
Agent in its individual capacity and not as Administrative Agent shall have the
same rights and powers as any other Lender and may exercise the same as though
it were not the Administrative Agent, and the Administrative Agent and its
Affiliates may accept deposits from, lend money to and generally engage in any
kind of business with the Borrower or any Subsidiary or other Affiliate thereof
as if it were not the Administrative Agent.

         Each Lender agrees (a) to reimburse the Administrative Agent, on
demand, in the amount of its pro rata share (based on its Commitment hereunder)
of any expenses incurred for the benefit of the Lenders by the Administrative
Agent, including counsel fees, that shall not have been reimbursed by the
Borrower and (b) to indemnify and hold harmless the Administrative Agent and any
of its directors, officers, employees or agents, on demand, in the amount of
such pro rata share, from and against any and all liabilities, taxes,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever that may be imposed
on, incurred by or asserted against it in its capacity as the Administrative
Agent or any of them in any way relating to or arising out of this Agreement or
any action taken or omitted by it or any of them under this Agreement, to the
extent the same shall not have been reimbursed by the Borrower, provided that no
Lender shall be liable to the Administrative Agent or any such other indemnified
person for any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements resulting
from the gross negligence or wilful misconduct of the Administrative Agent or
any of its directors, officers, employees or agents.

         Each Lender acknowledges that it has, independently and without
reliance upon the Administrative Agent or any other Lender and based on such
documents and information as it has deemed appropriate, made its own credit
analysis and decision to enter into this Agreement. Each Lender also
acknowledges that it will, independently and without reliance upon the
Administrative Agent or any other Lender and based on such documents and
information as it shall from time to time deem appropriate, continue to make its
own decisions in taking or not taking action under or based upon this Agreement,
any related agreement or any document furnished hereunder. Each Lender further
acknowledges that the Syndication Agent and the Documentation Agents have no
duties or obligations as such under this Agreement.

Register pursuant to the terms hereof as a Lender hereunder for all purposes of
this Agreement, notwithstanding notice to the contrary, and such entries in the
Register shall be conclusive absent manifest error. The Register shall be
available for inspection by the Borrower and any Lender, at any reasonable time
and from time to time upon reasonable prior notice.

         (e) Upon its receipt of a duly completed Assignment and Acceptance
executed by an assigning Lender and an assignee, an Administrative Questionnaire
completed in respect of the assignee (unless the assignee shall already be a
Lender hereunder), the processing and recordation fee referred to in paragraph
(b) above and, if required, the written consent of the Borrower and the
Administrative Agent to such assignment, the Administrative Agent shall (i)
accept such Assignment and Acceptance, (ii) record the information contained
therein in the Register and (iii) give prompt notice thereof to the Lenders and
the Borrower. No assignment shall be effective unless it has been recorded in
the Register as provided in this paragraph (e).

                                       49

         (f) Each Lender may without the consent of the Borrower or the
Administrative Agent sell participations to one or more banks or other entities
in all or a portion of its rights and obligations under this Agreement
(including all or a portion of its Commitment and the Loans owing to it);
provided, however, that (i) such Lender's obligations under this Agreement shall
remain unchanged, (ii) such Lender shall remain solely responsible to the other
parties hereto for the performance of such obligations, (iii) the participating
banks or other entities shall be entitled to the benefit of the cost protection
provisions contained in Sections 2.14, 2.16 and 2.20 (and shall have the duty to
mitigate under Section 2.21) to the same extent as if they were Lenders and (iv)
the Borrower, the Administrative Agent and the Lenders shall continue to deal
solely and directly with such Lender in connection with such Lender's rights and
obligations under this Agreement, and such Lender shall retain the sole right to
enforce the obligations of the Borrower relating to the Loans and to approve any
amendment, modification or waiver of any provision of this Agreement (other than
amendments, modifications or waivers decreasing any fees payable hereunder or
the amount of principal of or the rate at which interest is payable on the
Loans, extending any scheduled principal payment date or date fixed for the
payment of interest on the Loans or increasing or extending the Commitments).

         (g) Any Lender or participant may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this Section
9.04, disclose to the assignee or participant or proposed assignee or
participant any information relating to the Borrower furnished to such Lender by
or on behalf of the Borrower; provided that, prior to any such disclosure of
information designated by the Borrower as confidential, "Company Private" or
"Proprietary", each such assignee or participant or proposed assignee or
participant shall execute an agreement whereby such assignee or participant
shall agree (subject to customary exceptions) to preserve the confidentiality of
such confidential information on terms no less restrictive than those applicable
to the Lenders pursuant to Section 9.16.

         (h) Any Lender may at any time assign all or any portion of its rights
under this Agreement to a Federal Reserve Bank to secure extensions of credit by
such Federal Reserve Bank to such Lender; provided that no such assignment shall
release a Lender from any of its obligations hereunder or substitute any such
Bank for such Lender as a party hereto. In order to facilitate such an
assignment to a Federal Reserve Bank, the Borrower shall, at the request of the
assigning Lender, duly execute and deliver to the assigning Lender a promissory
note or notes evidencing the Loans made to the Borrower by the assigning Lender
hereunder.

         (i) The Borrower shall not assign or delegate any of its rights or
duties hereunder without the prior written consent of the Administrative Agent
and each Lender, and any attempted assignment without such consent shall be null
and void.

                                       50

          (j) Notwithstanding anything to the contrary contained herein, any
Lender (a "Granting Lender") may grant to a special purpose funding vehicle (an
"SPC") of such Granting Lender, identified as such in writing from time to time
by the Granting Lender to the Administrative Agent and the Borrower, the option
to provide to the Borrower all or any part of any Loan that such Granting Lender
would otherwise be obligated to make to the Borrower pursuant to Section 2.01 or
2.03(e), provided that (i) nothing herein shall constitute a commitment to make
any Loan by any SPC and (ii) if an SPC elects not to exercise such option or
otherwise fails to provide all or any part of such Loan, the Granting Lender
shall be obligated to make such Loan pursuant to the terms hereof. The making of
a Loan by an SPC hereunder shall utilize the Commitment of the Granting Lender
(and, if such Loan is a Competitive Loan, shall be deemed to utilize the
Commitments of all the Lenders) to the same extent, and as if, such Loan were
made by the Granting Lender. Each party hereto hereby agrees that no SPC shall
be liable for any indemnity or similar payment obligation under this Agreement
(all liability for which shall remain with the related Granting Lender). In
furtherance of the foregoing, each party hereto hereby agrees (which agreement
shall survive the termination of this Agreement) that, prior to the date that is
one year and one day after the payment in full of all outstanding senior
indebtedness of any SPC, it will not institute against, or join any other person
in instituting against, such SPC any bankruptcy, reorganization, arrangement,
insolvency or liquidation proceedings or similar proceedings under the laws of
the United States or any State thereof. In addition, notwithstanding anything to
the contrary contained in this Section 9.04 or in Section 9.16, any SPC may (i)
with notice to, but without the prior written consent of, the Borrower or the
Administrative Agent and without paying any processing fee therefor, assign all
or a portion of its interests in any Loans to its Granting Lender or to any
financial institutions providing liquidity and/or credit facilities to or for
the account of such SPC to fund the Loans made by such SPC or to support the
securities (if any) issued by such SPC to fund such Loans and (ii) disclose on a
confidential basis any non-public information relating to its Loans to any
rating agency, commercial paper dealer or provider of a surety, guarantee or
credit or liquidity enhancement to such SPC.

         SECTION 9.05. Expenses; Indemnity. (a) The Borrower agrees to pay all
out-of-pocket expenses incurred by the Agents in connection with the syndication
of the credit facilities provided for herein and the preparation and
administration of this Agreement or in connection with any amendments,
modifications or waivers of the provisions hereof (whether or not the
transactions hereby or thereby contemplated shall be consummated) or incurred by
the Administrative Agent or any Lender in connection with the enforcement or
protection of its rights in connection with this Agreement or in connection with
the Loans made hereunder, including the reasonable fees, charges and
disbursements of Cravath, Swaine & Moore, counsel for the Administrative Agent,
and, in connection with any such enforcement or protection, the reasonable fees,
charges and disbursements of any other counsel (including the allocated charges
of in-house counsel) for the Administrative Agent or any Lender. The Borrower
shall not be obligated to reimburse out-of-pocket legal expenses pursuant to the
preceding sentence for more than one law firm for the Agents incurred in
connection with the preparation of this Agreement or in connection with any
particular amendment, modification or waiver of the provisions hereof.
<PAGE>
                                       51

         (b) The Borrower agrees to indemnify the Administrative Agent and each
Lender, each Affiliate of any of the foregoing persons and each of their
respective directors, officers, employees and agents (each such person being
called an "Indemnitee") against, and to hold each Indemnitee harmless from, any
and all losses, claims, damages, liabilities and related expenses, including
reasonable counsel fees, charges and disbursements, incurred by or asserted
against any Indemnitee arising out of, in any way connected with, or as a result
of (i) the execution or delivery of this Agreement or any agreement or
instrument contemplated thereby, the performance by the parties thereto of their
respective obligations thereunder or the consummation of the Transactions and
the other transactions contemplated hereby, (ii) the use of the proceeds of the
Loans or (iii) any claim, litigation, investigation or proceeding relating to
any of the foregoing, whether or not any Indemnitee is a party thereto; provided
that such indemnity shall not, as to any Indemnitee, be available to the extent
that such losses, claims, damages, liabilities or related expenses result from
the gross negligence or wilful misconduct of such Indemnitee.

         (c) The provisions of this Section 9.05 shall remain operative and in
full force and effect regardless of the expiration of the term of this
Agreement, the consummation of the transactions contemplated hereby, the
repayment of any of the Loans, the expiration of the Commitments, the invalidity
or unenforceability of any term or provision of this Agreement, or any
investigation made by or on behalf of the Administrative Agent or any Lender.
All amounts due under this Section 9.05 shall be payable on written demand
therefor.

         SECTION 9.06. Right of Setoff. If an Event of Default shall have
occurred and be continuing, each Lender is hereby authorized at any time and
from time to time, to the fullest extent permitted by law, to set off and apply
any and all deposits (general or special, time or demand, provisional or final)
at any time held and other indebtedness at any time owing by such Lender to or
for the credit or the account of the Borrower against any of and all the
obligations of the Borrower now or hereafter existing under this Agreement held
by such Lender, irrespective of whether or not such Lender shall have made any
demand under this Agreement and although such obligations may be unmatured. The
rights of each Lender under this Section are in addition to other rights and
remedies (including other rights of setoff) which such Lender may have.

         SECTION 9.07.  APPLICABLE LAW.  THIS AGREEMENT SHALL BE CONSTRUED
IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW
YORK.

         SECTION 9.08. Waivers; Amendment. (a) No failure or delay of the
Administrative Agent or any Lender in exercising any power or right hereunder
shall operate as a waiver thereof, nor shall any single or partial exercise of
any such right or power, or any abandonment or discontinuance of steps to
enforce such a right or power, preclude any other or further exercise thereof or
the exercise of any other right or power. The rights and remedies of the
Administrative Agent and the Lenders hereunder are cumulative and are not
exclusive of any rights or remedies that they would otherwise have. No waiver of
any provision of this Agreement or consent to any departure by the Borrower
therefrom shall in any event be effective unless the same shall be permitted by
paragraph (b) below, and then such waiver or consent shall be effective only in
the specific instance and for the purpose for which given. No notice or demand
on the Borrower in any case shall entitle the Borrower to any other or further
notice or demand in similar or other circumstances.
<PAGE>
                                       52

         (b) Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to an agreement or agreements in writing
entered into by the Borrower and the Required Lenders; provided, however, that
no such agreement shall (i) decrease the principal amount

of, or extend the maturity of or any scheduled principal payment date or date
for the payment of any interest on any Loan or the payment of any Facility Fee,
or waive or excuse any such payment or any part thereof, or decrease the rate of
interest on any Loan, without the prior written consent of each Lender affected
thereby, (ii) change or extend the Commitment or decrease the Facility Fees of
any Lender without the prior written consent of such Lender, or (iii) amend or
modify the provisions of Section 2.17, the provisions of Section 9.04(i), the
provisions of this Section or the definition of the term "Required Lenders",
without the prior written consent of each Lender; provided further that no such
agreement shall amend, modify or otherwise affect the rights or duties of the
Administrative Agent hereunder without the prior written consent of the
Administrative Agent.

         SECTION 9.09. Interest Rate Limitation. Notwithstanding anything herein
to the contrary, if at any time the interest rate applicable to any Loan,
together with all fees, charges and other amounts which are treated as interest
on such Loan under applicable law (collectively the "Charges"), shall exceed the
maximum lawful rate (the "Maximum Rate") which may be contracted for, charged,
taken, received or reserved by the Lender holding such Loan in accordance with
applicable law, the rate of interest payable in respect of such Loan hereunder,
together with all Charges payable in respect thereof, shall be limited to the
Maximum Rate and, to the extent lawful, the interest and Charges that would have
been payable in respect of such Loan but were not payable as a result of the
operation of this Section shall be cumulated and the interest and Charges
payable to such Lender in respect of other Loans or periods shall be increased
(but not above the Maximum Rate therefor) until such cumulated amount, together
with interest thereon at the Federal Funds Effective Rate to the date of
repayment, shall have been received by such Lender.

         SECTION 9.10. Entire Agreement. This Agreement and the Fee Letter
constitute the entire contract among the parties relative to the subject matter
hereof. Any other previous agreement among the parties with respect to the
subject matter hereof is superseded by this Agreement. Nothing in this
Agreement, expressed or implied, is intended to confer upon any party other than
the parties hereto and thereto any rights, remedies, obligations or liabilities
under or by reason of this Agreement.

         SECTION 9.11. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY
IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT
IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR
INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT. EACH
PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY
OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD
NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B)
ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER
INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND
CERTIFICATIONS IN THIS SECTION 9.11.
<PAGE>
                                       53

         SECTION 9.12. Severability. In the event any one or more of the
provisions contained in this Agreement should be held invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained herein and therein shall not in any way be
affected or impaired thereby. The parties shall endeavor in good-faith
negotiations to replace the invalid, illegal or unenforceable provisions with
valid provisions the economic effect of which comes as close as possible to that
of the invalid, illegal or unenforceable provisions.

         SECTION 9.13. Counterparts. This Agreement may be executed in
counterparts (and by different parties hereto on different counterparts), each
of which shall constitute an original but all of which when taken together shall
constitute a single contract, and shall become effective as provided in Section
9.03. Delivery of an executed signature page to this Agreement by facsimile
transmission shall be effective as delivery of a manually signed counterpart of
this Agreement.

         SECTION 9.14. Headings. Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of this
Agreement and are not to affect the construction of, or to be taken into
consideration in interpreting, this Agreement.

         SECTION 9.15. Jurisdiction; Consent to Service of Process. (a) The
Borrower hereby irrevocably and unconditionally submits, for itself and its
property, to the nonexclusive jurisdiction of any New York State court or
Federal court of the United States of America sitting in New York City, and any
appellate court from any thereof, in any action or proceeding arising out of or
relating to this Agreement, or for recognition or enforcement of any judgment,
and each of the parties hereto hereby irrevocably and unconditionally agrees
that all claims in respect of any such action or proceeding may be heard and
determined in such New York State or, to the extent permitted by law, in such
Federal court. Each of the parties hereto agrees that a final judgment in any
such action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.
Nothing in this Agreement shall affect any right that the Administrative Agent
or any Lender may otherwise have to bring any action or proceeding relating to
this Agreement against the Borrower or its properties in the courts of any
jurisdiction.

         (b) The Borrower hereby irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, any objection which it may
now or hereafter have to the laying of venue of any suit, action or proceeding
arising out of or relating to this Agreement in any New York State or Federal
court. Each of the parties hereto hereby irrevocably waives, to the fullest
extent permitted by law, the defense of an inconvenient forum to the maintenance
of such action or proceeding in any such court.

         (c) Each party to this Agreement irrevocably consents to service of
process in the manner provided for notices in Section 9.01. Nothing in this
Agreement will affect the right of any party to this Agreement to serve process
in any other manner permitted by law.

                                       54

         SECTION 9.16. Confidentiality. The Administrative Agent and each of the
Lenders agrees to keep confidential (and to use its best efforts to cause its
respective agents and representatives to keep confidential) the Information (as
defined below) and all copies thereof, extracts therefrom and analyses or other
materials based thereon, except that the Administrative Agent or any Lender
shall be permitted to disclose Information (a) to such of its respective
officers, directors, employees, agents, affiliates and representatives as need
to know such Information, (b) to the extent requested by any regulatory
authority or examining authority, (c) to the extent otherwise required by
applicable laws and regulations or by any subpoena or similar legal process, (d)
in connection with any suit, action or proceeding relating to the enforcement of
its rights hereunder, (e) to the extent permitted by Section 9.04(g), or (f) to
the extent such Information (i) becomes publicly available other than as a
result of a breach of this Agreement or (ii) becomes available to the
Administrative Agent or any Lender on a nonconfidential basis from a source
other than the Borrower. For the purposes of this Section, "Information" shall
mean all financial statements, certificates, reports, agreements and information
(including all analyses, compilations and studies prepared by the Administrative
Agent or any Lender based on any of the foregoing) that are received from the
Borrower or any Subsidiary and related to the Borrower, any Subsidiary or any
employee, customer or supplier of the Borrower, other than any of the foregoing
that were available to the Administrative Agent or any Lender on a
nonconfidential basis prior to its disclosure thereto by the Borrower, and which
are in the case of Information provided after the date hereof, clearly
identified at the time of delivery as confidential, "Company Private" or
"Proprietary". The provisions of this Section 9.16 shall remain operative and in
full force and effect regardless of the expiration and term of this Agreement.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
duly executed by their respective authorized officers as of the day and year
first above written.

       CREDIT AGREEMENT dated as of May 2, 1997 (this "Agreement"), among
RAYTHEON COMPANY, a Delaware corporation (the "Borrower"), the Lenders (as
defined in Article I), BANCAMERICA SECURITIES, INC., as Syndication Agent (in
such capacity, the "Syndication Agent"), CANADIAN IMPERIAL BANK OF COMMERCE and
CREDIT SUISSE FIRST BOSTON, as Documentation Agents (in such capacity, each a
"Documentation Agent" and, collectively, the "Documentation Agents"), and THE
CHASE MANHATTAN BANK, a New York banking corporation, as administrative agent
(in such capacity, the  "Administrative Agent") for the Lenders.

         Pursuant to an asset purchase agreement dated as of January 4, 1997
(the "Asset Purchase Agreement"), between the Borrower and Texas Instruments
Incorporated, a Delaware corporation ("TI"), the Borrower intends, subject to
the conditions set forth in the Asset Purchase Agreement (such term and each
other capitalized term used but not defined herein having the meaning given to
it in Article I), to acquire all the assets and assume certain of the
liabilities (the "TI Acquisition") of the defense business of TI. The Borrower
also intends, subject to the conditions set forth in the Hughes Merger
Agreement, to combine its business with the defense business of HE Holdings,
Inc., a Delaware corporation ("Hughes"), by merging (the "Hughes Merger") with
and into Hughes pursuant to an Agreement and Plan of Merger dated as of January
16, 1997 (the "Hughes Merger Agreement"), between the Borrower and Hughes. The
Borrower has requested the Lenders to extend credit in the form of Revolving
Loans at any time and from time to time prior to the Maturity Date, in an
aggregate principal amount at any time outstanding not in excess of
$3,000,000,000. The Borrower has requested the Lenders to provide a procedure
pursuant to which the Borrower may invite the Lenders to bid on an uncommitted
basis on short-term Borrowings by the Borrower. The proceeds of the Loans are to
be used (a) to finance the TI Acquisition, (b) to repay in full all outstanding
amounts under the Borrower's existing Credit Agreement dated as of April 28,
1995 (as amended, the "Existing Credit Agreement"), and (c) to pay related fees
and expenses. In addition, the proceeds of the Loans may be used to provide
working capital and for other general corporate purposes of the Borrower,
including commercial paper backup.

         The Lenders are willing to extend such credit to the Borrower on the
terms and subject to the conditions set forth herein. Accordingly, the parties
hereto agree as follows:


                                    ARTICLE I

                                   Definitions

     "ABR Borrowing" shall mean a Borrowing comprised of ABR Loans.

     "ABR Loan" shall mean any Loan bearing interest at the Alternate Base
Rate in accordance with the provisions of Article II.

                                       3


     "Affiliate" shall mean, when used with respect to a specified person,
another person that directly, or indirectly through one or more intermediaries,
Controls or is Controlled by or is under common Control with the person

plus 1/2 of 1%. If for any reason the Administrative Agent shall have determined
(which determination shall be conclusive absent manifest error) that it is
unable to ascertain the Base CD Rate or the Federal Funds Effective Rate or both
for any reason, including the inability or failure of the Administrative Agent
to obtain sufficient quotations in accordance with the terms hereof, the
Alternate Base Rate shall be determined without regard to clause (b) or (c), or
both, of the preceding sentence, as appropriate, until the circumstances giving
rise to such inability no longer exist. Any change in the Alternate Base Rate
due to a change in the Prime Rate, the Base CD Rate or the Federal Funds
Effective Rate shall be effective on the effective date of such change in the
Prime Rate, the Base CD Rate or the Federal Funds Effective Rate, respectively.

     "Applicable Percentage" shall mean, for any day, with respect to any
Eurodollar Loan (other than any Eurodollar Competitive Loan), or with respect to
the Facility Fees, as the case may be, the applicable percentage set forth below
under the caption "Eurodollar Spread" or "Fee Percentage", as the case may be,
based upon the ratings by S&P and Moody's, respectively, applicable on such date
to the Index Debt:

                                           Spread         Percentage
Category 1

         AA- or higher by S&P
         Aa3 or higher by Moody's           .135%            .045%

Category 2

         A+ or A by S&P
         A1 or A2 by Moody's                .175%            .050%

Category 3

         A- by S&P
         A3 by Moody's                      .195%            .055%

Category 5

         BBB by S&P
         Baa2 by Moody's                    .250%            .100%

Category 6
         BBB- by S&P
         Baa3 by Moody's                    .325%            .125%

Category 7

         Less than BBB- by S&P
         Less than Baa3 by Moody's          .400%            .150%

     For purposes of the foregoing, (i) if either Moody's or S&P shall not
have in effect a rating for the Index Debt (other than by reason of the
circumstances referred to in the last sentence of this paragraph), then such
rating agency shall be deemed to have established a rating in Category 7; (ii)
if the ratings established or deemed to have been established by Moody's and S&P
for the Index Debt shall fall within different Categories, the Applicable
Percentage shall be based on the higher of the two ratings unless the ratings
differ by more than one category, in which case the governing rating shall be
the rating next below the higher of the two; (iii) until the aggregate
commitments under this Agreement, the 5-year Agreement and the Hughes Credit
Agreements are reduced below $8,000,000,000, the Eurodollar Spread will be
increased by 0.05% at all times that the aggregate amounts outstanding hereunder
and under the 5-year Agreement exceed 66 2/3% of the aggregate commitments
(whether used or unused) hereunder and under the 5-year Agreement; and (iv) if
the ratings established or deemed to have been established by Moody's and S&P
for the Index Debt shall be changed (other than as a result of a change in the
rating system of Moody's or S&P), such change shall be effective as of the date
on which it is first announced by the applicable rating agency. Each change in
the Applicable Percentage shall apply during the period commencing on the
effective date of such change and ending on the date immediately preceding the
effective date of the next such change. If the rating system of Moody's or S&P
shall change, or if either such rating agency shall cease to be in the business
of rating corporate debt obligations, the Borrower and the Lenders shall
negotiate in good faith to amend this definition to reflect such changed rating
system or the non- availability of ratings from such rating agency and, pending
the effectiveness of any such amendment, the Applicable Percentage shall be
determined by reference to the rating most recently in effect prior to such
change or cessation.

         "Asset Sale" shall mean the sale, assignment, transfer or other
disposition by the Borrower or any of its Subsidiaries to any person other than
the Borrower or any of its wholly owned Subsidiaries of any capital stock or

accounts receivable, in each case disposed of in the ordinary course of
business; provided, however, that any asset sale or series of related asset
sales described above having a value not in excess of $25,000,000 shall not be
deemed an "Asset Sale" for purposes of this Agreement.

         "Assignment and Acceptance" shall mean an assignment and acceptance
entered into by a Lender and an assignee, and accepted by the Administrative
Agent, in the form of Exhibit B or such other form as shall be approved by the

Dollars of over $100,000 with maturities approximately equal to three months.

date of any change in any reserve percentage. The term "Assessment Rate" shall
mean for any date the annual rate (rounded upwards, if necessary, to the next
1/100 of 1%) most recently estimated by the Administrative Agent as the then
current net annual assessment rate that will be employed in determining amounts

this Agreement unless the context shall otherwise require. Except as otherwise
expressly provided herein, (a) any reference to this Agreement shall mean this
Agreement as amended, restated, supplemented or otherwise modified from time to
time and (b) all terms of an accounting or financial nature shall be construed

                                  The Credits

         SECTION 2.01. Commitments. Subject to the terms and conditions and
relying upon the representations and warranties herein set forth, each Lender
agrees, severally and not jointly, to make Revolving Loans to the Borrower, at
any time and from time to time on or after the Closing Date, and until the
earlier of the Maturity Date and the termination of the Commitment of such
Lender in accordance with the terms hereof, in an aggregate principal amount at
any time outstanding that will not result in (a)(i) such Lender's Revolving
Credit Exposure exceeding (ii) such Lender's Commitment or (b)(i) the aggregate
amount of outstanding Loans exceeding (ii) the Total Commitment. Within the
limits set forth in the preceding sentence, the Borrower may borrow, pay or
prepay and reborrow Revolving Loans on or after the Closing Date and prior to
the Maturity Date, subject to the terms, conditions and limitations set forth
herein.

         SECTION 2.02. Loans. (a) Each Revolving Loan shall be made as part of a
Borrowing consisting of Loans made by the Lenders ratably in accordance with
their respective Commitments; provided, however, that the failure of any Lender
to make any Loan shall not in itself relieve any other Lender of its obligation
to lend hereunder (it being understood, however, that no Lender shall be
responsible for the failure of any other Lender to make any Loan required to be
made by such other Lender). Each Competitive Loan shall be made in accordance
with the procedures set forth in Section 2.03. The Loans comprising any
Borrowing shall be in an aggregate principal amount that is (i) an integral
multiple of $1,000,000 and not less than $10,000,000 or (ii) equal to the
remaining available balance of the Total Commitment.

<PAGE>
                                       13

         (b) Subject to Sections 2.09 and 2.15, each Competitive Borrowing shall
be comprised entirely of Eurodollar Competitive Loans or Fixed Rate Loans, and
each Revolving Credit Borrowing shall be comprised entirely of ABR Loans or
Eurodollar Loans as the Borrower may request pursuant to Section 2.03 or 2.04,
as applicable. Each Lender may at its option make any Eurodollar Loan by causing
any domestic or foreign branch or Affiliate of such Lender to make such Loan;
provided that any exercise of such option shall not affect the obligation of the
Borrower to repay such Loan in accordance with the terms of this Agreement.
Borrowings of more than one Type may be outstanding at the same time; provided,
however, that the Borrower shall not be entitled to request any Borrowing that,
if made, would result in more than 15 Eurodollar Borrowings outstanding
hereunder at any time. For purposes of the foregoing, Borrowings having
different Interest Periods, regardless of whether they commence on the same
date, shall be considered separate Borrowings.

         (c) Each Lender shall make each Loan to be made by it hereunder on the
proposed date thereof by wire transfer of immediately available funds to such
account in New York City as the Administrative Agent may designate not later
than 11:00 a.m., New York City time, and the Administrative Agent shall by 12:00
(noon), New York City time, credit the amounts so received to an account with
the Administrative Agent designated by the Borrower in the applicable Borrowing
Request or Competitive Bid Request, which account must be in the name of the
Borrower or, if a Borrowing shall not occur on such date because any condition
precedent herein specified shall not have been met, return the amounts so
received to the respective Lenders.

         (d) Unless the Administrative Agent shall have received notice from a
Lender prior to the date of any Borrowing that such Lender will not make
available to the Administrative Agent such Lender's portion of such Borrowing,
the Administrative Agent may assume that such Lender has made such portion
available to the Administrative Agent on the date of such Borrowing in
accordance with paragraph (c) above and the Administrative Agent may, in
reliance upon such assumption, make available to the Borrower on such date a
corresponding amount. If the Administrative Agent shall have so made funds
available then, to the extent that such Lender shall not have made such portion
available to the Administrative Agent, such Lender and the Borrower severally
agree to repay to the Administrative Agent within one Business Day of demand
therefor such corresponding amount together with interest thereon, for each day
from the date such amount is made available to the Borrower until the date such
amount is repaid to the Administrative Agent at (i) in the case of the Borrower,
the interest rate applicable at the time to the Loans comprising such Borrowing
and (ii) in the case of such Lender, a rate determined by the Administrative
Agent to represent its cost of overnight or short-term funds (which
determination shall be conclusive absent manifest error). If such Lender shall
repay to the Administrative Agent such corresponding amount, such amount shall
constitute such Lender's Loan as part of such Borrowing for purposes of this
Agreement.

         (e) Notwithstanding any other provision of this Agreement, the Borrower
shall not be entitled to request any Borrowing if the Interest Period requested
with respect thereto would end after the Maturity Date.

         SECTION 2.03. Competitive Bid Procedure. (a) In order to request
Competitive Bids, the Borrower shall hand deliver or telecopy to the
Administrative Agent a duly completed Competitive Bid Request (i) in the case of
a Eurodollar Competitive Borrowing, not later than 10:00 a.m., New York City
time, four Business Days before the proposed date of such Borrowing and (ii) in
the case of a Fixed Rate Borrowing, not later than 10:00 a.m., New York City
time, one Business Day before the proposed date of such Borrowing. A Competitive
Bid Request shall not be made within five Business Days after the date of any
previous Competitive Bid Request. No ABR Loan shall be requested in, or made
pursuant to, a Competitive Bid Request. A Competitive Bid Request that does not
conform substantially to the format of Exhibit D-1 may be rejected by the
Administrative Agent and the Administrative Agent shall notify the Borrower of
such rejection as promptly as practicable. Each Competitive Bid Request shall
refer to this Agreement and specify (i) whether the Borrowing being requested is

<PAGE>
                                       14

to be a Eurodollar Competitive Borrowing or a Fixed Rate Borrowing; (ii) the
date of such Borrowing (which shall be a Business Day); (iii) the number and the
location of the account to which funds are to be disbursed (which shall be an
account that complies with the requirements of Section 2.02(c)); (iv) the
aggregate principal amount of such Borrowing, which shall be a minimum of
$10,000,000 and an integral multiple of $1,000,000 and not greater than the
Total Commitment then available; and (v) the Interest Period with respect
thereto (which may not end after the Maturity Date). Promptly after its receipt
of a Competitive Bid Request that is not rejected, the Administrative Agent
shall by telecopy in the form set forth in Exhibit D-2 invite the Lenders to bid
to make Competitive Loans pursuant to the Competitive Bid Request.

         (b) Each Lender may make one or more Competitive Bids to the Borrower
responsive to a Competitive Bid Request. Each Competitive Bid by a Lender must
be received by the Administrative Agent by telecopy in the form of Exhibit D-3,
(i) in the case of a Eurodollar Competitive Borrowing, not later than 9:30 a.m.,
New York City time, three Business Days before the proposed date of such
Competitive Borrowing and (ii) in the case of a Fixed Rate Borrowing, not later
than 9:30 a.m., New York City time, on the proposed date of such Competitive
Borrowing. Competitive Bids that do not conform substantially to the format of
Exhibit D-3 may be rejected by the Administrative Agent, and the Administrative
Agent shall notify the applicable Lender as promptly as practicable. Each
Competitive Bid shall refer to this Agreement and specify (x) the principal
amount (which shall be a minimum of $5,000,000 and an integral multiple of
$1,000,000 and which may equal the entire principal amount of the Competitive
Borrowing requested by the Borrower) of the Competitive Loan or Loans that the
Lender is willing to make, (y) the Competitive Bid Rate or Rates at which the
Lender is prepared to make such Loan or Loans and (z) the Interest Period
applicable to such Loan or Loans and the last day thereof.

         (c) The Administrative Agent shall promptly notify the Borrower by
telecopy of the Competitive Bid Rate and the principal amount of each
Competitive Loan in respect of which a Competitive Bid shall have been made and
the identity of the Lender that shall have made each bid.

         (d) The Borrower may, subject only to the provisions of this paragraph
(d), accept or reject any Competitive Bid. The Borrower shall notify the
Administrative Agent by telephone, confirmed by telecopy in the form of a
Competitive Bid Accept/Reject Letter, whether and to what extent it has
decided to accept or reject each Competitive Bid, (x) in the case of a
Eurodollar Competitive Borrowing, not later than 10:30 a.m., New York City time,
three Business Days before the date of the proposed Competitive Borrowing and
(y) in the case of a Fixed Rate Borrowing, not later than 10:30 a.m., New York
City time, on the proposed date of the Competitive Borrowing; provided, however,
that (i) the failure of the Borrower to give such notice shall be deemed to be a
rejection of each Competitive Bid, (ii) the Borrower shall not accept a
Competitive Bid made at a particular Competitive Bid Rate if the Borrower has
decided to reject a Competitive Bid made at a lower Competitive Bid Rate, (iii)
the aggregate amount of the Competitive Bids accepted by the Borrower shall not
exceed (but may be less than) the principal amount specified in the Competitive
Bid Request, (iv) if the Borrower shall accept a Competitive Bid or Bids made at
a particular Competitive Bid Rate but the amount of such Competitive Bid or Bids
would cause the total amount to be accepted by the Borrower to exceed the amount
specified in the Competitive Bid Request, then the Borrower shall accept a
portion of such Competitive Bid or Bids in an amount equal to the amount
specified in the Competitive Bid Request less the amount of all other
Competitive Bids so accepted, which acceptance, in the case of multiple
Competitive Bids at such Competitive Bid Rate, shall be made pro rata in
accordance with the amount of each such Bid and (v) except pursuant to clause
(iv) above, no Competitive Bid shall be accepted for a Competitive Loan unless
such Competitive Loan is in a minimum principal amount of $5,000,000 and an
integral multiple of $1,000,000; provided further, however, that if a
Competitive Loan must be in an amount less than $5,000,000 because of the
provisions of clause (iv) above, such Competitive Loan may be for a minimum of
$1,000,000 or any integral multiple thereof, and in calculating the pro rata
allocation of acceptances of portions of multiple Competitive Bids at a
<PAGE>
                                       15

particular Competitive Bid Rate pursuant to clause (iv) the amounts shall be
rounded to integral multiples of $1,000,000 in a manner determined by the
Borrower. A notice given by the Borrower pursuant to this paragraph (d) shall be
irrevocable.

         (e) The Administrative Agent shall promptly notify each bidding Lender
by telecopy whether or not its Competitive Bid has been accepted (and, if so, in
what amount and at what Competitive Bid Rate), and each successful bidder will
thereupon become bound, upon the terms and subject to the conditions hereof, to
make the Competitive Loan in respect of which its Competitive Bid has been
accepted.

         (f) If the Administrative Agent shall elect to submit a Competitive Bid
in its capacity as a Lender, it shall submit such Competitive Bid directly to
the Borrower at least one quarter of an hour earlier than the time by which the
other Lenders are required to submit their Competitive Bids to the
Administrative Agent pursuant to paragraph (b) above.

         SECTION 2.04. Borrowing Procedure. In order to request a Borrowing
(other than a Competitive Borrowing, as to which this Section 2.04 shall not
apply), the Borrower shall hand deliver or telecopy to the Administrative Agent
a duly completed Borrowing Request (a) in the case of a Eurodollar Borrowing,
not later than 11:00 a.m., New York City time, three Business Days before a
proposed Borrowing and (b) in the case of an ABR Borrowing, not later than 10:00
a.m., New York City time, on the day of a proposed Borrowing. Each Borrowing

complies with the requirements of Section 2.02(c)); (iv) the amount of such
Borrowing; and (v) if such Borrowing is to be a Eurodollar Borrowing, the
Interest Period with respect thereto; provided, however, that, notwithstanding
any contrary specification in any Borrowing Request, each requested Borrowing
shall comply with the requirements set forth in Section 2.02. If no election as
to the Type of Borrowing is specified in any such notice, then the requested
Borrowing shall be an ABR Borrowing. If no Interest Period with respect to any
Eurodollar Borrowing is specified in any such notice, then the Borrower shall be
deemed to have selected an Interest Period of one month's duration. The
Administrative Agent shall promptly advise the Lenders of any notice given
pursuant to this Section 2.04 (and the contents thereof), and of each Lender's
portion of the requested Borrowing.

         SECTION 2.05. Evidence of Debt; Repayment of Loans. (a) The Borrower
hereby agrees that the outstanding principal balance of each Revolving Loan
shall be payable on the Maturity Date and the outstanding principal balance of
each Competitive Loan shall be payable on the last day of the Interest Period
applicable thereto. Each Loan shall bear interest from and including the date of
such Loan on the outstanding principal balance thereof as set forth in Section
2.07.

         (b) Each Lender shall maintain in accordance with its usual practice an
account or accounts evidencing the indebtedness of the Borrower to such Lender
resulting from each Loan made by such Lender from time to time, including the
amounts of principal and interest payable and paid such Lender from time to time
under this Agreement.

         (c) The Administrative Agent shall maintain accounts in which it will
record (i) the amount of each Loan made hereunder, the Type thereof and the
Interest Period applicable thereto, (ii) the amount of any principal or interest
due and payable or to become due and payable from the Borrower to each Lender
hereunder and (iii) the amount of any sum received by the Administrative Agent
hereunder from the Borrower and each Lender's share thereof.

         (d) The entries made in the accounts maintained pursuant to paragraphs
(b) and (c) of this Section 2.05 shall be prima facie evidence of the existence
and amounts of the obligations therein recorded; provided, however, that the
failure of any Lender or the Administrative Agent to maintain such accounts or
<PAGE>
                                       16

any error therein shall not in any manner affect the obligations of the Borrower
to repay the Loans in accordance with their terms.

         (e) Notwithstanding any other provision of this Agreement, in the event
any Lender shall request and receive a promissory note payable to such Lender
and its registered assigns, the interests represented by such note shall at all
times (including after any assignment of all or part of such interests pursuant
to Section 9.04) be represented by one or more promissory notes payable to the
payee named therein or its registered assigns.

         SECTION 2.06. Fees. (a) The Borrower agrees to pay to each Lender,
through the Administrative Agent, on the last day of March, June, September and
December in each year, and on the date on which the Commitment of such Lender
shall be terminated as provided herein, a facility fee (a "Facility Fee") equal
to the Applicable Percentage per annum in effect from time to time on the
average daily amount of the Commitment of such Lender (whether used or unused)
during the preceding quarter (or shorter period commencing with the date hereof
or ending with the Maturity Date or the date on which the Commitment of such
Lender shall expire or be terminated). All Facility Fees shall be computed on
the basis of the actual number of days elapsed in a year of 360 days. The
Facility Fee due to each Lender shall commence to accrue on the date of this
Agreement and shall cease to accrue on the earlier of the Maturity Date and the
date on which the Commitment of such Lender shall be terminated as provided
herein.

         (b) The Borrower agrees to pay to each of the Agents or their
Affiliates, for their own account, the fees set forth in the Fee Letter at the
times and in the amounts specified therein (the "Agents' Fees").

         (c) All Fees shall be paid on the dates due, in immediately available
funds. Once paid, none of the Fees shall be refundable under any circumstances.

         SECTION 2.07. Interest on Loans. (a) Subject to the provisions of
Section 2.08, the Loans comprising each ABR Borrowing shall bear interest
(computed on the basis of the actual number of days elapsed over a year of 365
or 366 days, as the case may be, when the Alternate Base Rate is determined by
reference to the Prime Rate and over a year of 360 days at all other times) at a
rate per annum equal to the Alternate Base Rate.

         (b) Subject to the provisions of Section 2.08, the Loans comprising
each Eurodollar Borrowing shall bear interest (computed on the basis of the
actual number of days elapsed over a year of 360 days) at a rate per annum equal
to (i) in the case of each Revolving Loan, the LIBO Rate for the Interest Period
in effect for such Borrowing plus the Applicable Percentage in effect from time
to time and (ii) in the case of each Competitive Loan, the LIBO Rate for the
Interest Period in effect for such Borrowing plus the Margin offered by the
Lender making such Loan and accepted by the Borrower pursuant to Section 2.03.

          (c) Subject to the provisions of Section 2.08, each Fixed Rate Loan
shall bear interest (computed on the basis of the actual number of days elapsed
over a year of 360 days) at a rate per annum equal to the fixed rate of interest
offered by the Lender making such Loan and accepted by the Borrower pursuant to
Section 2.03.

         (d) Interest on each Loan shall be payable on the Interest Payment
Dates applicable to such Loan except as otherwise provided in this Agreement.
The applicable Alternate Base Rate or LIBO Rate for each Interest Period or day
within an Interest Period, as the case may be, shall be determined by the
Administrative Agent, and such determination shall be conclusive absent manifest
error.

         SECTION 2.08. Default Interest. If the Borrower shall default in the
payment of the principal of or interest on any Loan or any other amount becoming
due hereunder, by acceleration or otherwise, the Borrower shall on demand from
time to time pay interest, to the extent permitted by law, on such defaulted
<PAGE>
                                       17

amount to but excluding the date of actual payment (after as well as before
judgment) (a) in the case of overdue principal, at the rate otherwise applicable
to such Loan pursuant to Section 2.07 plus 2.00% per annum and (b) in all other
cases, at a rate per annum (computed on the basis of the actual number of days
elapsed over a year of 365 or 366 days, as the case may be, when determined by
reference to the Prime Rate and over a year of 360 days at all other times)
equal to the sum of the Alternate Base Rate plus 2.00%.

         SECTION 2.09. Alternate Rate of Interest. In the event, and on each
occasion, that on the day two Business Days prior to the commencement of any
Interest Period for a Eurodollar Borrowing the Administrative Agent shall have
determined that (a) Dollar deposits in the principal amounts of the Loans
comprising such Borrowing are not generally available in the London interbank
market, or (b) the rates at which such Dollar deposits are being offered will
not adequately and fairly reflect the cost to Lenders having Commitments
representing at least 20% of the Total Commitment of making or maintaining
Eurodollar Loans during such Interest Period, or (c) reasonable means do not
exist for ascertaining the LIBO Rate, the Administrative Agent shall, as soon as
practicable thereafter, give written or telecopy notice of such determination to
the Borrower and the Lenders. In the event of any such determination (other than
any such determination pursuant to clause (b) of the preceding sentence, to the
extent the circumstances giving rise to such determination would also give
Lenders the right to demand additional amounts pursuant to Section 2.14), until
the Administrative Agent shall have advised the Borrower and the Lenders that
the circumstances giving rise to such notice no longer exist, (i) any request by
the Borrower for a Eurodollar Revolving Credit Borrowing pursuant to Section
2.04 shall be deemed to be a request for an ABR Borrowing and (ii) any request
by the Borrower for a Eurodollar Competitive Borrowing pursuant to Section 2.03
shall be of no force and effect and shall be denied by the Administrative Agent.
Each determination by the Administrative Agent hereunder shall be conclusive
absent manifest error.

         SECTION 2.10.  Termination and Reduction of Commitments.

         (a)  The Commitments shal automatically terminate on the Maturity Date.

         (b) Upon at least three Business Days' prior irrevocable written or
telecopy notice to the Administrative Agent, the Borrower may at any time in
whole permanently terminate, or from time to time in part permanently reduce,
the Commitments; provided, however, that (i) each partial reduction of the
Commitments shall be in an integral multiple of $1,000,000 and in a minimum
amount of $10,000,000 and (ii) the Total Commitment shall not be reduced to an
amount that is less than the sum of the Aggregate Revolving Credit Exposure and
the aggregate outstanding principal amount of the Competitive Loans at the time.

         (c)  Each reduction in the Commitments hereunder shall be made ratably
 among the Lenders
in accordance with their respective Commitments.  The Borrower shall pay to the
Administrative Agent for the account of the applicable Lenders, on the date of
each termination or reduction, the Facility Fees on the amount of the
Commitments so terminated or reduced accrued to but excluding the date of such
termination or reduction.

         SECTION 2.11. Conversion and Continuation of Revolving Credit
Borrowings. The Borrower shall have the right at any time upon prior irrevocable
notice to the Administrative Agent (a) not later than 10:00 a.m., New York City
time, on the day of conversion, to convert any Eurodollar Borrowing into an ABR
Borrowing, (b) not later than 10:00 a.m., New York City time, three Business
Days prior to conversion or continuation, to convert any ABR Borrowing into a
Eurodollar Borrowing or to continue any Eurodollar Borrowing as a Eurodollar
Borrowing for an additional Interest Period, and (c) not later than 10:00 a.m.,
New York City time, three Business Days prior to conversion, to convert the
Interest Period with respect to any Eurodollar Borrowing to another permissible
Interest Period, subject in each case to the following:
<PAGE>
                                       18


     (ii) if less than all the outstanding principal amount of any Borrowing
shall be converted or continued, then each resulting Borrowing shall satisfy the
limitations specified in Sections 2.02(a) and 2.02(b) regarding the principal
amount and maximum number of Borrowings of the relevant Type;

     (iii) each conversion shall be effected by each Lender by recording for the
account of such Lender the new Loan of such Lender resulting from such
conversion and reducing the Loan (or portion thereof) of such Lender being
converted by an equivalent principal amount; accrued interest on any Eurodollar
Loan (or portion thereof) being converted shall be paid by the Borrower at the
time of conversion;

     (iv) if any Eurodollar Borrowing is converted at a time other than the end
of the Interest Period applicable thereto, the Borrower shall pay, upon demand,
any amounts due to the Lenders pursuant to Section 2.16;


     (vi) any portion of a Eurodollar Borrowing that cannot be converted into or
contin ued as a Eurodollar Borrowing by reason of the immediately preceding
clause shall be automatically converted at the end of the Interest Period in
effect for such Borrowing into an ABR Borrowing.

     Each notice pursuant to this Section 2.11 shall be irrevocable and shall
refer to this Agreement and specify (i) the identity and amount of the Borrowing
that the Borrower requests be converted or continued, (ii) whether such
Borrowing is to be converted into or continued as a Eurodollar Borrowing or an
ABR Borrowing, (iii) if such notice requests a conversion, the date of such
conversion (which shall be a Business Day) and (iv) if such Borrowing is to be
converted into or continued as a Eurodollar Borrowing, the Interest Period with
respect thereto (which may not end after the Maturity Date). If no Interest
Period is specified in any such notice with respect to any conversion into or
continuation as a Eurodollar Borrowing, the Borrower shall be deemed to have
selected an Interest Period of one month's duration. The Administrative Agent
shall advise the other Lenders of any notice given pursuant to this Section 2.11
and of each Lender's portion of any converted or continued Borrowing. If the
Borrower shall not have given notice in accordance with this Section 2.11 to
continue any Borrowing into a subsequent Interest Period (and shall not
otherwise have given notice in accordance with this Section 2.11 to convert such
Borrowing), such Borrowing shall, at the end of the Interest Period applicable
thereto (unless repaid pursuant to the terms hereof), automatically be continued
into a new Interest Period as an ABR Borrowing. The Borrower shall not have the
right to continue or convert the Interest Period with respect to any Competitive
Borrowing pursuant to this Section 2.11.

         SECTION 2.12. Optional Prepayment. (a) The Borrower shall have the
right at any time and from time to time to prepay any Borrowing (other than a
Competitive Borrowing), in whole or in part, upon at least three Business Days'
prior written or telecopy notice (or telephone notice promptly confirmed by
written or telecopy notice) to the Administrative Agent before 11:00 a.m., New
York City time; provided, however, that each partial prepayment shall be in an
amount that is an integral multiple of $1,000,000 and not less than $10,000,000.
The Borrower shall not have the right to prepay any Competitive Borrowing.

         (b) In the event of any termination of the Commitments, the Borrower
shall repay or prepay all its outstanding Revolving Credit Borrowings on the
date of such termination. In the event of any partial reduction of the
Commitments, then (i) at or prior to the effective date of such reduction, the
<PAGE>
                                       19

Administrative Agent shall notify the Borrower and the Lenders of the Aggregate
Revolving Credit Exposure and (ii) if the Aggregate Revolving Credit Exposure
would exceed the available Total Commitment after giving effect to such
reduction, the Borrower shall, on the date of such reduction, repay or prepay
Revolving Credit Borrowings in an amount sufficient to eliminate such excess.

         (c) Each notice of prepayment shall specify the prepayment date and the
principal amount of each Borrowing (or portion thereof) to be prepaid, shall be
irrevocable and shall commit the Borrower to prepay such Borrowing by the amount
stated therein on the date stated therein. All prepayments under this Section
2.12 shall be subject to Section 2.16 but otherwise without premium or penalty.
All prepayments of Eurodollar Loans under this Section 2.12 shall be accompanied
by accrued interest on the principal amount being prepaid to the date of
payment.

         SECTION 2.13. Required Commitment Reductions and Prepayments. (a) If
prior to the second anniversary of the Closing Date the Borrower or any
Subsidiary shall complete any Asset Sale, then within three Business Days of the
receipt by the Borrower or any Subsidiary of any Net Cash Proceeds therefrom,
the Borrower shall on such date permanently reduce the Commitments and/or the
commitments under the 5-year Agreement and/or, after the consummation of the
Hughes Merger, the commitments under one or both of the Hughes Credit
Agreements, at the option of the Borrower, by an aggregate amount, which when
aggregated with all required commitment reductions made pursuant to Section
2.13(a) or (b) prior to such date, shall equal at least 75% of the aggregate Net
Cash Proceeds of such Asset Sale and all other Asset Sales and Debt Issuances
made prior to such date and, to the extent the outstanding Loans would exceed
the Total Commitment as so reduced, prepay any Revolving Loans then outstanding
on or prior to the effectiveness of such reduction by an amount sufficient to
eliminate such excess.

         (b) If prior to the second anniversary of the Closing Date the Borrower
or any Subsidiary shall complete any Debt Issuance, then within three Business
Days of the receipt by the Borrower or any Subsidiary of any Net Cash Proceeds
therefrom, the Borrower shall on such date permanently reduce the Commitments
and/or the commitments under the 5-year Agreement and/or, after the consummation
of the Hughes Merger, the commitments under one or both of the Hughes Credit
Agreements, at the option of the Borrower, by an aggregate amount, which when
aggregated with all required commitment reductions made pursuant to Section
2.13(a) or (b) prior to such date, shall equal at least 75% of the aggregate Net
Cash Proceeds of such Debt Issuance and all other Debt Issuances and Asset Sales
made prior to such date and, to the extent the outstanding Loans would exceed
the Total Commitment as so reduced, prepay any Revolving Loans then outstanding
on or prior to the effectiveness of such reduction by an amount sufficient to
eliminate such excess.

     (c) In the event any prepayment required by Section 2.13(a) or (b) with
respect to any Revolving Loan would become due on a date that is not the last
day of the relevant Interest Period therefor and as a result thereof the
Borrower would incur liabilities under Section 2.16, then (i) if the last day of
the relevant Interest Period for such Loan would occur within 180 days of the
date on which such prepayment is otherwise due, and (ii) no Default or Event of
Default shall have occurred and be continuing, such prepayment may be made at
the Borrower's election on the last day of the relevant Interest Period for such
Loan and, pending such prepayment, the Borrower shall deposit such Net Cash
Proceeds with the Administrative Agent which shall hold such Net Cash Proceeds
for the benefit of the Lenders, in an interest bearing account, until such time
as such proceeds can be applied towards payment of the Loans in accordance with
the provisions of this Agreement without resulting in any liability to the
Borrower under Section 2.16. Until such Loans are so prepaid they shall continue
to accrue interest as provided hereunder, provided that all interest which may
accrue on any amounts so held in escrow shall be delivered by the Administrative
Agent to the Borrower following prepayment of the principal of and accrued
interest on such Loans.

         SECTION 2.14. Reserve Requirements; Change in Circumstances. (a)
Notwithstanding any other provision of this Agreement, if after the date of this
Agreement any change in applicable law or regulation or in the interpretation or
administration thereof by any Governmental Authority charged with the
interpretation or administration thereof (whether or not having the force of
law) shall impose, modify or deem applicable any reserve, special deposit or
similar requirement against assets of, deposits with or for the account of or
credit extended by any Lender or shall impose on such Lender or the London
interbank market any other condition affecting this Agreement or Eurodollar
Loans or Fixed Rate Loans made by such Lender, and the result of any of the
foregoing shall be to increase the cost to such Lender of making or maintaining
any Eurodollar Loan or Fixed Rate Loan, or to reduce the amount of any sum
received or receivable by such Lender hereunder (whether of principal, interest
or otherwise) by an amount deemed by such Lender to be material, then the
Borrower will pay to such Lender upon demand such additional amount or amounts
as will compensate such Lender for such additional costs incurred or reduction
suffered.

         (b) If any Lender shall have determined that the adoption after the
date hereof of any law, rule, regulation, agreement or guideline regarding
capital adequacy, or any change after the date hereof in any such law, rule,
regulation, agreement or guideline (whether such law, rule, regulation,
agreement or guideline has been adopted) or in the interpretation or
administration thereof by any Governmental Authority charged with the
interpretation or administration thereof, or compliance by any Lender (or any
lending office of such Lender) or any Lender's holding company with any request
or directive regarding capital adequacy (whether or not having the force of law)
of any Governmental Authority has or would have the effect of reducing the rate
of return on such Lender's capital or on the capital of such Lender's holding
company, if any, as a consequence of this Agreement or the Loans made by such
Lender pursuant hereto to a level below that which such Lender or such Lender's
holding company could have achieved but for such applicability, adoption, change
or compliance (taking into consideration such Lender's policies and the policies
of such Lender's holding company with respect to capital adequacy) by an amount
deemed by such Lender to be material, then from time to time the Borrower shall
pay to such Lender such additional amount or amounts as will compensate such
Lender or such Lender's holding company for any such reduction suffered.

         (c) A certificate of a Lender setting forth the amount or amounts
necessary to compensate such Lender or its holding company (including the
calculation thereof) as specified in paragraph (a) or (b) above shall be
delivered to the Borrower and shall be conclusive absent manifest error. The
Borrower shall pay such Lender the amount shown as due on any such certificate
delivered by it within 10 days after its receipt of the same.

         (d) Failure or delay on the part of any Lender to demand compensation
for any increased costs or reduction in amounts received or receivable or
reduction in return on capital shall not constitute a waiver of such Lender's
right to demand such compensation. The protection of this Section shall be
available to each Lender regardless of any possible contention of the invalidity
or inapplicability of the law, rule, regulation, agreement, guideline or other
change or condition that shall have occurred or been imposed. Notwithstanding
any other provision of this Section, no Lender shall be entitled to demand
compensation hereunder in respect of any Competitive Loan if it shall have been
aware of the event or circumstance giving rise to such demand at the time it
submitted the Competitive Bid pursuant to which such Loan was made.

     SECTION 2.15. Change in Legality. (a) Notwithstanding any other provision
of this Agreement, if, after the date hereof, any change in any law or
regulation or in the interpretation thereof by any Governmental Authority
charged with the administration or interpretation thereof shall make it unlawful
for any Lender to make or maintain any Eurodollar Loan or to give effect to its
obligations as contemplated hereby with respect to any Eurodollar Loan, then, by
written notice to the Borrower and to the Administrative Agent:
<PAGE>
                                       21

     (i) such Lender may declare that Eurodollar Loans will not thereafter (for
the duration of such unlawfulness) be made by such Lender hereunder (or be
continued for additional Interest Periods and ABR Loans will not thereafter (for
such duration) be converted into Eurodollar Loans), whereupon such Lender shall
not submit a Competitive Bid in response to a request for a Eurodollar
Competitive Loan and any request for a Eurodollar Borrowing (or to convert an
ABR Borrowing to a Eurodollar Borrowing or to continue a Eurodollar Borrowing
for an additional Interest Period) shall, as to such Lender only, be deemed a
request for an ABR Loan unless such declaration shall be subsequently withdrawn
(or a request to continue an ABR Loan as such for an additional Interest Period
or to convert a Eurodollar Loan into an ABR Loan, as the case may be); and

     (ii) such Lender may require that all outstanding Eurodollar Loans made by
it be converted to ABR Loans, in which event all such Eurodollar Loans shall be
automatically converted to ABR Loans as of the effective date of such notice as
provided in paragraph (b) below.

In the event any Lender shall exercise its rights under (i) or (ii) above, all
payments and prepayments of principal that would otherwise have been applied to
repay the Eurodollar Loans that would have been made by such Lender or the
converted Eurodollar Loans of such Lender shall instead be applied to repay the
ABR Loans made by such Lender in lieu of, or resulting from the conversion of,
such Eurodollar Loans.

         (b) For purposes of this Section 2.15, a notice to the Borrower by any
Lender shall be effective as to each Eurodollar Loan made by such Lender, if
lawful, on the last day of the Interest Period currently applicable to such
Eurodollar Loan; in all other cases such notice shall be effective on the date
of receipt by the Borrower.

         SECTION 2.16. Indemnity. The Borrower shall indemnify each Lender
against any loss or expense that such Lender may sustain or incur as a
consequence of any event, other than a default by such Lender in the performance
of its obligations hereunder, that results in (i) such Lender receiving or being
deemed to receive any amount on account of the principal of any Fixed Rate Loan
or Eurodollar Loan prior to the end of the Interest Period in effect therefor,
(ii) the conversion of any Eurodollar Loan to an ABR Loan, or the conversion of
the Interest Period with respect to any Eurodollar Loan, in each case prior to
the end of the Interest Period in effect therefor or (iii) any Fixed Rate Loan
or Eurodollar Loan to be made by such Lender (including any Eurodollar Loan to
be made pursuant to a conversion or continuation under Section 2.11) not being
made after notice of such Loan shall have been given by the Borrower hereunder
(any of the events referred to in this sentence being called a "Breakage
Event"). In the case of any Breakage Event, such loss shall include an amount
equal to the excess, as reasonably determined by such Lender, of (i) its cost of
obtaining funds for the Eurodollar Loan or Fixed Rate Loan that is the subject
of such Breakage Event for the period from the date of such Breakage Event to
the last day of the Interest Period in effect (or that would have been in
effect) for such Loan over (ii) the amount of interest likely to be realized by
such Lender in redeploying the funds released or not utilized by reason of such
Breakage Event for such period. A certificate of any Lender setting forth any
amount or amounts that such Lender is entitled to receive pursuant to this
Section 2.16 shall be delivered to the Borrower and shall be conclusive absent
manifest error.

     SECTION 2.17. Pro Rata Treatment. Except as provided in the two succeeding
sentences with respect to Competitive Borrowings and as required under Section
2.15, each Borrowing, each payment or prepayment of principal of any Borrowing,
each payment of interest on the Loans, each payment of the Facility Fees, each
reduction of the Commitments and each continuation or conversion of any
Borrowing to a Borrowing of any Type shall be allocated pro rata among the
Lenders in accordance with their respective Commitments (or, if such Commitments
shall have expired or been terminated, in accordance with the respective
principal amounts of their outstanding Loans). Each payment of principal of any
Competitive Borrowing shall be allocated pro rata among the Lenders
participating in such Borrowing in accordance with the respective principal
amounts of their outstanding Competitive Loans comprising such Borrowing. Each
<PAGE>
                                       22

payment of interest on any Competitive Borrowing shall be allocated pro rata
among the Lenders participating in such Borrowing in accordance with the
respective amounts of accrued and unpaid interest on their outstanding
Competitive Loans comprising such Borrowing. For purposes of determining the
available Commitments of the Lenders at any time, each outstanding Competitive
Borrowing shall be deemed to have utilized the Commitments of the Lenders
(including those Lenders that shall not have made Loans as part of such
Competitive Borrowing) pro rata in accordance with such respective Commitments.
Each Lender agrees that in computing such Lender's portion of any Borrowing to
be made hereunder, the Administrative Agent may, in its discretion, round each
Lender's percentage of such Borrowing to the next higher or lower whole Dollar
amount.

         SECTION 2.18. Sharing of Setoffs. Each Lender agrees that if it shall,
through the exercise of a right of banker's lien, setoff or counterclaim against
the Borrower, or pursuant to a secured claim under Section 506 of Title 11 of
the United States Code or other security or interest arising from, or in lieu
of, such secured claim, received by such Lender under any applicable bankruptcy,
insolvency or other similar law or otherwise, or by any other means, obtain
payment (voluntary or involuntary) in respect of any Revolving Loan or Loans as
a result of which the unpaid principal portion of its Revolving Loans shall be
proportionately less than the unpaid principal portion of the Revolving Loans of
any other Lender, it shall be deemed simultaneously to have purchased from such
other Lender at face value, and shall promptly pay to such other Lender the
purchase price for, a participation in the Revolving Loans of such other Lender,
so that the aggregate unpaid principal amount of the Revolving Loans and
participations in Revolving Loans held by each Lender shall be in the same
proportion to the aggregate unpaid principal amount of all Revolving Loans then
outstanding as the principal amount of its Revolving Loans prior to such
exercise of banker's lien, setoff or counterclaim or other event was to the
principal amount of all Revolving Loans outstanding prior to such exercise of
banker's lien, setoff or counterclaim or other event; provided, however, that,
if any such purchase or purchases or adjustments shall be made pursuant to this
Section and the payment giving rise thereto shall thereafter be recovered, such
purchase or purchases or adjustments shall be rescinded to the extent of such
recovery and the purchase price or prices or adjustment restored without
interest. The Borrower expressly consents to the foregoing arrangements and
agrees that any Lender holding a participation in a Revolving Loan deemed to
have been so purchased may exercise any and all rights of banker's lien, setoff
or counterclaim with respect to any and all moneys owing by the Borrower to such
Lender by reason thereof as fully as if such Lender had made a Revolving Loan
directly to the Borrower in the amount of such participation.

         SECTION 2.19. Payments. (a) The Borrower shall make each payment
(including principal of or interest on any Borrowing or any Fees or other
amounts) hereunder not later than 12:00 (noon), New York City time, on the date
when due in immediately available Dollars, without defense, setoff or
counterclaim. Each such payment shall be made to the Administrative Agent at its
offices at 270 Park Avenue, New York, New York.

         (b) Whenever any payment (including principal of or interest on any
Borrowing or any Fees or other amounts) hereunder shall become due, or otherwise
would occur, on a day that is not a Business Day, such payment may be made on
the next succeeding Business Day, and such extension of time shall in such case
be included in the computation of interest or Fees, if applicable.

         SECTION 2.20. Taxes. (a) Any and all payments by the Borrower hereunder
shall be made, in accordance with Section 2.19, free and clear of and without
deduction for any and all current or future taxes, levies, imposts, deductions,
charges or withholdings, and all liabilities with respect thereto, excluding (i)
income taxes imposed on the net income of the Administrative Agent or any Lender
(or any transferee or assignee thereof, including a participation holder (any
such entity a "Transferee")) and (ii) franchise taxes imposed on the net income
of the Administrative Agent or any Lender (or Transferee), in each case by the
jurisdiction under the laws of which the Administrative Agent or such Lender 

<PAGE>
                                       23

(or Transferee) is organized or any political subdivision thereof (all such 
nonexcluded taxes, levies, imposts, deductions, charges,
withholdings and liabilities, collectively or individually, being called
"Taxes"). If the Borrower shall be required to deduct any Taxes from or in
respect of any sum payable hereunder to the Administrative Agent or any Lender
(or any Transferee), (i) the sum payable shall be increased by the amount (an
"additional amount") necessary so that after making all required deductions
(including deductions applicable to additional sums payable under this Section
2.20) the Administrative Agent or such Lender (or Transferee), as the case may
be, shall receive an amount equal to the sum it would have received had no such
deductions been made, (ii) the Borrower shall make such deductions and (iii) the
Borrower shall pay the full amount deducted to the relevant Governmental
Authority in accordance with applicable law.

         (b) In addition, the Borrower agrees to pay to the relevant
Governmental Authority in accordance with applicable law any current or future
stamp or documentary taxes or any other excise or property taxes, charges or
similar levies that arise from any payment made hereunder or from the execution,
delivery or registration of, or otherwise with respect to, this Agreement
("Other Taxes").

         (c) The Borrower will indemnify the Administrative Agent and each
Lender (or Transferee) for the full amount of Taxes and Other Taxes paid by the
Administrative Agent or such Lender (or Transferee), as the case may be, and any
liability (including penalties, interest and expenses (including reasonable
attorney's fees and expenses)) arising therefrom or with respect thereto,
whether or not such Taxes or Other Taxes were correctly or legally asserted by
the relevant Governmental Authority. A certificate as to the amount of such
payment or liability prepared by the Administrative Agent or a Lender (or
Transferee), or the Administrative Agent on its behalf, absent manifest error,
shall be final, conclusive and binding for all purposes. Such indemnification
shall be made within 30 days after the date the Administrative Agent or any
Lender (or Transferee), as the case may be, makes written demand therefor.

         (d) If the Administrative Agent or a Lender (or Transferee) receives a
refund in respect of any Taxes or Other Taxes as to which it has been
indemnified by the Borrower or with respect to which the Borrower has paid
additional amounts pursuant to this Section 2.20, it shall within 30 days from
the date of such receipt pay over such refund to the Borrower (but only to the
extent of indemnity payments made, or additional amounts paid, by the Borrower
under this Section 2.20 with respect to the Taxes or Other Taxes giving rise to
such refund), net of all out-of-pocket expenses of the Administrative Agent or
such Lender (or Transferee) and without interest (other than interest paid by
the relevant Governmental Authority with respect to such refund); provided,
however, that the Borrower, upon the request of the Administrative Agent or such
Lender (or Transferee), shall repay the amount paid over to the Borrower (plus
penalties, interest or other charges) to the Administrative Agent or such Lender
(or Transferee) in the event the Administrative Agent or such Lender (or
Transferee) is required to repay such refund to such Governmental Authority.

         (e) As soon as practicable after the date of any payment of Taxes or
Other Taxes by the Borrower to the relevant Governmental Authority, the Borrower
will deliver to the Administrative Agent, at its address referred to in Section
9.01, the original or a certified copy of a receipt issued by such Governmental
Authority evidencing payment thereof.

         (f) Without prejudice to the survival of any other agreement contained
herein, the agreements and obligations contained in this Section 2.20 shall
survive the payment in full of the principal of and interest on all Loans made
hereunder.

         (g) Each Lender (or Transferee) that is organized under the laws of a
jurisdiction other than the United States, any State thereof or the District of
Columbia (a "Non-U.S. Lender") shall deliver to each of the Borrower and the
Administrative Agent two copies of either United States Internal Revenue Service
Form 1001 or Form 4224, or, in the case of a Non-U.S. Lender claiming exemption
from U.S. Federal withholding tax under Section 871(h) or 881(c) of the Code
with respect to payments of "portfolio interest", a Form W-8, or any subsequent

<PAGE>
                                       24

versions thereof or successors thereto (and, if such Non-U.S. Lender delivers a
Form W-8, a certificate representing that such Non-U.S. Lender is not a bank for
purposes of Section 881(c) of the Code, is not a 10-percent shareholder
(within the meaning of Section 871(h)(3)(B) of the Code) of the Borrower and is
not a controlled foreign corporation related to the Borrower (within the meaning
of Section 864(d)(4) of the Code)), properly completed and duly executed by such
Non-U.S. Lender claiming complete exemption from, or reduced rate of, U.S.
Federal withholding tax on payments by the Borrower under this Agreement. Such
forms shall be delivered by each Non-U.S. Lender on or before the date it
becomes a party to this Agreement (or, in the case of a Transferee that is a
participation holder, on or before the date such participation holder becomes a
Transferee hereunder) and on or before the date, if any, such Non-U.S. Lender
changes its applicable lending office by designating a different lending office
(a "New Lending Office"). In addition, each Non-U.S. Lender shall deliver such
forms promptly upon the obsolescence or invalidity of any form previously
delivered by such Non-U.S. Lender. Notwithstanding any other provision of this
Section 2.20(g), a Non-U.S. Lender shall not be required to deliver any form
pursuant to this Section 2.20(g) that such Non-U.S. Lender is not legally able
to deliver.

         (h) The Borrower shall not be required to indemnify any Non-U.S. Lender
or to pay any additional amounts to any Non-U.S. Lender, in respect of United
States Federal withholding tax pursuant to paragraph (a) or (c) above to the
extent that (i) the obligation to withhold amounts with respect to United States
Federal withholding tax existed on the date such Non-U.S. Lender became a party
to this Agreement (or, in the case of a Transferee that is a participation
holder, on the date such participation holder became a Transferee hereunder) or,
with respect to payments to a New Lending Office, the date such Non-U.S. Lender
designated such New Lending Office with respect to a Loan; provided, however,
that this paragraph (h) shall not apply (x) to any Transferee or New Lending
Office that becomes a Transferee or New Lending Office as a result of an
assignment, participation, transfer or designation made at the request of the
Borrower and (y) to the extent the indemnity payment or additional amounts any
Transferee, or any Lender (or Transferee), acting through a New Lending Office,
would be entitled to receive (without regard to this paragraph (h)) do not
exceed the indemnity payment or additional amounts that the person making the
assignment, participation or transfer to such Transferee, or Lender (or
Transferee) making the designation of such New Lending Office, would have been
entitled to receive in the absence of such assignment, participation, transfer
or designation or (ii) the obligation to pay such additional amounts would not
have arisen but for a failure by such Non-U.S. Lender to comply with the
provisions of paragraph (g) above.

         (i) Nothing contained in this Section 2.20 shall require any Lender (or
any Transferee) or the Administrative Agent to make available any of its tax
returns (or any other information that it deems to be confidential or
proprietary).

         SECTION 2.21. Assignment of Commitments Under Certain Circumstances;
Duty to Mitigate. (a) In the event (i) any Lender delivers a certificate
requesting compensation pursuant to Section 2.14, (ii) any Lender delivers a
notice described in Section 2.15 or (iii) the Borrower is required to pay any
additional amount to any Lender or any Governmental Authority on account of any
Lender pursuant to Section 2.20, the Borrower may, at its sole expense and
effort, upon notice to such Lender and the Administrative Agent, require such
Lender to transfer and assign, without recourse (in accordance with and subject
to the restrictions contained in Section 9.04), all of its interests, rights and
obligations under this Agreement to an assignee which shall assume such assigned
obligations (which assignee may be another Lender, if a Lender accepts such
assignment); provided that (x) such assignment shall not conflict with any law,
rule or regulation or order of any court or other Governmental Authority having
jurisdiction, (y) the Borrower shall have received the prior written consent of
the Administrative Agent, which consent shall not unreasonably be withheld, and
(z) the Borrower or such assignee shall have paid to the affected Lender in
immediately available funds an amount equal to the sum of the principal of and
<PAGE>
                                       25

interest accrued to the date of such payment on the outstanding Loans of such
Lender plus all Fees and other amounts accrued for the account of such Lender
hereunder (including any amounts under Section 2.14 and Section 2.16); provided
further that if prior to any such transfer and assignment the circumstances or
event that resulted in such Lender's claim for compensation under Section 2.14
or notice under Section 2.15 or the amounts paid pursuant to Section 2.20, as
the case may be, cease to cause such Lender to suffer increased costs or
reductions in amounts received or receivable or reduction in return on capital,
or cease to have the consequences specified in Section 2.15, or cease to result 
in amounts being payable under Section 2.20, as the case may be (including as a
result of any action taken by such Lender pursuant to paragraph (b) below), or 
if such Lender shall waive its right to claim further compensation under Section
2.14 in respect of such circumstances or event or shall withdraw its notice
under Section 2.15 or shal waive its right to further payments under Section 
2.20 in respect of such circumstances or event, as the case may be, then such 
Lender shall not thereafter be required to make any such transfer and assignment
hereunder.

         (b) If (i) any Lender shall request compensation under Section 2.14,
(ii) any Lender delivers a notice described in Section 2.15 or (iii) the
Borrower is required to pay any additional amount to any Lender or any
Governmental Authority on account of any Lender, pursuant to Section 2.20, then,
such Lender shall use reasonable efforts (which shall not require such Lender to
incur an unreimbursed loss or unreimbursed cost or expense or otherwise take any
action inconsistent with its internal policies or legal or regulatory
restrictions or suffer any disadvantage or burden deemed by it to be
significant) (x) to file any certificate or document reasonably requested in
writing by the Borrower or (y) to assign its rights and delegate and transfer
its obligations hereunder to another of its offices, branches or affiliates, if
such filing or assignment would reduce its claims for compensation under Section
2.14 or enable it to withdraw its notice pursuant to Section 2.15 or would
reduce amounts payable pursuant to Section 2.20, as the case may be, in the
future. The Borrower hereby agrees to pay all reasonable costs and expenses
incurred by any Lender in connection with any such filing, assignment,
delegation and transfer.

                                   ARTICLE III

                         Representations and Warranties

         The Borrower represents and warrants to the Administrative Agent and
each of the Lenders that:

         SECTION 3.01. Organization; Powers. The Borrower and each of the
Significant Subsidiaries (a) is a corporation duly organized, validly existing
and in good standing under the laws of the jurisdiction of its organization, (b)
has all requisite power and authority to own its property and assets and to
carry on its business as now conducted and as proposed to be conducted and (c)
is qualified to do business in, and is in good standing in, every jurisdiction
where such qualification is required, except where the failure so to qualify
could not reasonably be expected to result in a Material Adverse Effect. The
Borrower has the corporate power and authority to execute, deliver and perform
its obligations under this Agreement and to borrow hereunder. Schedule 3.01 sets
forth each Significant Subsidiary of the Borrower in existence on the Closing
Date.

         SECTION 3.02. Authorization. The execution, delivery and performance by
the Borrower of this Agreement and the borrowings hereunder (collectively, the
"Transactions") (a) have been duly authorized by all requisite corporate and, if
required, stockholder action and (b) will not (i) violate (A) any provision of
law, statute, rule or regulation, or of the certificate or articles of
incorporation or other constitutive documents or by-laws of the Borrower or any
Significant Subsidiary, (B) any order of any Governmental Authority or (C) any
material provision of any material indenture, agreement or other instrument to
which the Borrower or any Significant Subsidiary is a party or by which any of
them or any of their property is or may be bound, (ii) be in material conflict
with, result in a material breach of or constitute (alone or with notice or
<PAGE>
                                       26

lapse of time or both) a material default under, or give rise to any right to
accelerate or to require the prepayment, repurchase or redemption of any
obligation under any such material indenture, agreement or other instrument or
(iii) result in the creation or imposition of any Lien upon or with respect to
any property or assets now owned or hereafter acquired by the Borrower or any
Significant Subsidiary.

         SECTION 3.03. Enforceability. This Agreement has been duly executed and
delivered by the Borrower and constitutes a legal, valid and binding obligation
of the Borrower enforceable against the Borrower in accordance with its terms.

         SECTION 3.04. Governmental Approvals. No action, consent or approval
of, registration or filing with or any other action by any Governmental
Authority is or will be required in connection with the Transactions, except
those which have been made or obtained.

         SECTION 3.05. Financial Statements. (a) The Borrower has heretofore
furnished to the Lenders its consolidated balance sheet, statement of income and
statement of cash flows as of and for the fiscal year ended December 31, 1996,
audited by and accompanied by the opinion of Coopers & Lybrand, independent
public accountants. Such financial statements present fairly the financial
condition and results of operations of the Borrower and its consolidated
Subsidiaries as of such date and for such period. Such balance sheet and the
notes thereto disclose all material liabilities, direct or contingent, of the
Borrower and its consolidated Subsidiaries as of the date thereof. Such
financial statements were prepared in accordance with GAAP applied on a
consistent basis.

         (b) The Borrower has heretofore delivered to the Lenders its unaudited
pro forma consolidated financial statements as of December 31, 1996, prepared
giving effect to the TI Acquisition as if it had occurred on such date. Such pro
forma financial statements have been prepared in good faith by the Borrower,
based on the assumptions used to prepare the pro forma financial information
contained in the Confidential Information Memorandum (which assumptions are
believed by the Borrower on the date hereof to be reasonable), are based on the
best information available to the Borrower as of the date of delivery thereof,
accurately reflect all adjustments required to be made to give effect to the TI
Acquisition and present fairly on a pro forma basis the estimated consolidated
financial position of the Borrower and its consolidated Subsidiaries as of
December 31, 1996, assuming that the TI Acquisition had actually occurred at
January 1, 1996.

         SECTION 3.06. No Material Adverse Change. There has been no material
adverse change in the business, assets, operations or condition, financial or
otherwise, of the Borrower and the Subsidiaries, taken as a whole, since
December 31, 1996.

         SECTION 3.07. Litigation; Compliance with Laws. (a) Except as set forth
on Schedule 3.07, there are not any actions, suits or proceedings at law or in
equity or by or before any Governmental Authority now pending or, to the
knowledge of the Borrower, threatened against or affecting the Borrower or any
Subsidiary or any business, property or rights of any such person (i) that
involve this Agreement or the Transactions or (ii) as to which there is a
reasonable possibility of an adverse determination and that, if adversely
determined, could reasonably be expected, individually or in the aggregate, to
result in a Material Adverse Effect. Except as set forth on Schedule 3.07, to
the knowledge of the Borrower, on the Closing Date there are not any actions,
suits or proceedings at law or in equity or by or before any Governmental
Authority now pending or threatened against or affecting the defense business of
TI or any business, property or rights relating thereto (i) that involve this
Agreement or the Transactions or (ii) as to which there is a reasonable
possibility of an adverse determination and that, if adversely determined, could
reasonably be expected, individually or in the aggregate, to result in a
Material Adverse Effect.
<PAGE>
                                       27

         (b) None of the Borrower or any of the Subsidiaries or any of their
respective material properties or assets is in violation of, nor will the
continued operation of their material properties and assets as currently
conducted violate, any law, rule or regulation, or is in default with respect to
any judgment, writ, injunction, decree or order of any Governmental Authority
(including any of the foregoing relating to the environment), where such
violation or default could reasonably be expected to result in a Material
Adverse Effect.

         SECTION 3.08.  Federal Reserve Regulations. (a)  Neither the Borrower
nor any of the Subsidiaries is engaged principally, or as one of its important
activities, in the business of extending credit for the purpose of buying or
carrying Margin Stock.

         (b) No part of the proceeds of any Loan will be used, whether directly
or indirectly, and whether immediately, incidentally or ultimately for any
purpose that entails a violation of, or that is inconsistent with, the
provisions of the Regulations of the Board, including Regulation G, U or X.
Margin Stocks do not constitute 25% or more of the fair market value of the
assets of the Borrower and the Subsidiaries subject to the restrictions of
Section 6.01.

         SECTION 3.09. Investment Company Act; Public Utility Holding Company
Act. Neither the Borrower nor any Subsidiary is (a) an "investment company" as
defined in, or subject to regulation under, the Investment Company Act of 1940
or (b) a "holding company" as defined in, or subject to regulation under, the
Public Utility Holding Company Act of 1935.

         SECTION 3.10. Tax Returns. Each of the Borrower and the Subsidiaries
has filed or caused to be filed all Federal and all material state, local and
foreign tax returns or materials required to have been filed by it and has paid
or caused to be paid all taxes shown to be due and payable by it on such returns
and all assessments received by it, except taxes that are being contested in
good faith by appropriate proceedings and for which the Borrower or such
Subsidiaries, as applicable, shall have set aside on its books adequate reserves
in accordance with GAAP.

         SECTION 3.11. No Material Misstatements. None of (a) the information
contained in the Confidential Information Memorandum and relating to the
Borrower and its Subsidiaries, (b) to the best knowledge of the Borrower, the
information contained in the Confidential Memorandum and relating to TI or the
assets and businesses to be acquired in the TI Acquisition or (c) any other
information, report, financial statement, exhibit or schedule furnished in
writing by or on behalf of the Borrower to the Administrative Agent or any
Lender in connection with the negotiation of this Agreement or included herein
or delivered pursuant hereto contained, contains or will contain any material
misstatement of fact or omitted, omits or will omit to state any material fact
necessary to make the statements therein, in the light of the circumstances
under which they were, are or will be made, not misleading; provided that to the
extent any such information, report, financial statement, exhibit or schedule
was based upon or constitutes a forecast or projection, the Borrower represents
only that it acted in good faith and utilized reasonable assumptions and due
care in the preparation of such information, report, financial statement,
exhibit or schedule.

         SECTION 3.12. Employee Benefit Plans. Each of the Borrower and its
ERISA Affiliates is in compliance in all material respects with the applicable
provisions of ERISA and the Code and the regulations and published
interpretations thereunder. No ERISA Event has occurred or is reasonably
expected to occur that, when taken together with all other such ERISA Events,
could reasonably be expected to result in a Material Adverse Effect. The present
value of all benefit liabilities under each Plan (based on those assumptions
used to fund such Plan) did not, as of the last annual valuation date applicable
thereto before the Closing Date, exceed the fair market value of the assets of
such Plan, and the present value of all benefit liabilities of all underfunded
Plans (based on those assumptions used to fund each such Plan) did not, as of
the last annual valuation dates applicable thereto before the Closing Date,
exceed the fair market value of the assets of all such underfunded Plans.

respect) to the effect that such consolidated financial statements fairly

on Form 11-K or any successor form); and

     (e) promptly, from time to time, such other information regarding the
operations, business affairs and financial condition of the Borrower or any
Significant Subsidiary, or compliance with the terms of this Agreement, as the
Administrative Agent or any Lender may reasonably request.

         SECTION 5.05. Litigation and Other Notices. Promptly upon any
Responsible Officer of the Borrower obtaining knowledge of any of the following,
furnish to the Administrative Agent and each Lender written notice of the
following:

     (b) the filing or commencement of, or any notice of intention of any person
to file or commence, any action, suit or proceeding, whether at law or in equity
or by or before any Governmental Authority, against the Borrower or any
Affiliate thereof that could reasonably be expected to result in a Material
Adverse Effect or materially impair the Borrower's ability to perform its
obligations under this Agreement;

                                  ARTICLE VIII

                            The Administrative Agent

         In order to expedite the transactions contemplated by this Agreement,
The Chase Manhattan Bank is hereby appointed to act as Administrative Agent on
behalf of the Lenders. Each of the Lenders and each assignee of any such Lender
hereby irrevocably authorizes the Administrative Agent to take such actions on
behalf of such Lender or assignee and to exercise such powers as are
specifically delegated to the Administrative Agent by the terms and provisions
hereof, together with such actions and powers as are reasonably incidental
thereto. The Administrative Agent is hereby expressly authorized by the Lenders,
without hereby limiting any implied authority, (a) to receive on behalf of the
Lenders all payments of principal of and interest on the Loans and all other
amounts due to the Lenders hereunder, and promptly to distribute to each Lender
its proper share of each payment so received; (b) to give notice on behalf of
each of the Lenders to the Borrower of any Event of Default specified in this
Agreement of which the Administrative Agent has actual knowledge acquired in
connection with its agency hereunder; and (c) to distribute to each Lender
copies of all notices, financial statements and other materials delivered by the
Borrower pursuant to this Agreement as received by the Administrative Agent.

         Neither the Administrative Agent nor any of its directors, officers,
employees or agents shall be liable as such for any action taken or omitted by
any of them except for its or his own gross negligence or wilful misconduct, or
be responsible for any statement, warranty or representation herein or the
contents of any document delivered in connection herewith, or be required to
ascertain or to make any inquiry concerning the performance or observance by the
Borrower of any of the terms, conditions, covenants or agreements contained in
this Agreement. The Administrative Agent shall not be responsible to the Lenders
for the due execution, genuineness, validity, enforceability or effectiveness of
this Agreement or any other instruments or agreements. The Administrative Agent
<PAGE>
                                       37

shall in all cases be fully protected in acting, or refraining from acting, in
accordance with written instructions signed by the Required Lenders (or, when
expressly required hereunder, all the Lenders) and, except as otherwise
specifically provided herein, such instructions and any action or inaction
pursuant thereto shall be binding on all the Lenders. The Administrative Agent
shall, in the absence of knowledge to the contrary, be entitled to rely on any
instrument or document believed by it in good faith to be genuine and correct
and to have been signed or sent by the proper person or persons. Neither the
Administrative Agent nor any of its directors, officers, employees or agents
shall have any responsibility to the Borrower on account of the failure of or
delay in performance or breach by any Lender of any of its obligations hereunder
or to any Lender on account of the failure of or delay in performance or breach
by any other Lender or the Borrower of any of their respective obligations
hereunder or in connection herewith. The Administrative Agent may execute any
and all duties here under by or through agents or employees and shall be
entitled to rely upon the advice of legal counsel selected by it with respect to
all matters arising hereunder and shall not be liable for any action taken or
suffered in good faith by it in accordance with the advice of such counsel.

         The Lenders hereby acknowledge that the Administrative Agent shall be
under no duty to take any discretionary action permitted to be taken by it
pursuant to the provisions of this Agreement unless it shall be requested in
writing to do so by the Required Lenders.

         Subject to the appointment and acceptance of a successor Administrative
Agent as provided below, the Administrative Agent may resign at any time by
notifying the Lenders and the Borrower. Upon any such resignation, the Required
Lenders shall have the right, with the consent of the Borrower (which consent
shall not be unreasonably withheld), to appoint a successor. If no successor
shall have been so appointed by the Required Lenders and shall have accepted
such appointment within 30 days after the retiring Administrative Agent gives
notice of its resignation, then the retiring Administrative Agent may, on behalf
of the Lenders, appoint a successor Administrative Agent which shall be a bank
with an office in New York, New York, having a combined capital and surplus of
at least $500,000,000 or an Affiliate of any such bank. Upon the acceptance of
any appointment as Administrative Agent hereunder by a successor bank, such
successor shall succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Administrative Agent and the
retiring Administrative Agent shall be discharged from its duties and
obligations hereunder. After the Administrative Agent's resignation hereunder,
the provisions of this Article and Section 9.05 shall continue in effect for its
benefit in respect of any actions taken or omitted to be taken by it while it
was acting as Administrative Agent.

         With respect to the Loans made by it hereunder, the Administrative
Agent in its individual capacity and not as Administrative Agent shall have the
same rights and powers as any other Lender and may exercise the same as though
it were not the Administrative Agent, and the Administrative Agent and its
Affiliates may accept deposits from, lend money to and generally engage in any
kind of business with the Borrower or any Subsidiary or other Affiliate thereof
as if it were not the Administrative Agent.

         Each Lender agrees (a) to reimburse the Administrative Agent, on
demand, in the amount of its pro rata share (based on its Commitment hereunder)
of any expenses incurred for the benefit of the Lenders by the Administrative
Agent, including counsel fees, that shall not have been reimbursed by the
Borrower and (b) to indemnify and hold harmless the Administrative Agent and any
of its directors, officers, employees or agents, on demand, in the amount of
such pro rata share, from and against any and all liabilities, taxes,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever that may be imposed
on, incurred by or asserted against it in its capacity as the Administrative
Agent or any of them in any way relating to or arising out of this Agreement or
any action taken or omitted by it or any of them under this Agreement, to the
extent the same shall not have been reimbursed by the Borrower, provided that no
Lender shall be liable to the Administrative Agent or any such other indemnified
person for any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements resulting
from the gross negligence or wilful misconduct of the Administrative Agent or
any of its directors, officers, employees or agents.

         Each Lender acknowledges that it has, independently and without
reliance upon the Administrative Agent or any other Lender and based on such
documents and information as it has deemed appropriate, made its own credit
analysis and decision to enter into this Agreement. Each Lender also
acknowledges that it will, independently and without reliance upon the
Administrative Agent or any other Lender and based on such documents and
information as it shall from time to time deem appropriate, continue to make its
own decisions in taking or not taking action under or based upon this Agreement,
any related agreement or any document furnished hereunder. Each Lender further
acknowledges that the Syndication Agent and the Documentation Agents have no
duties or obligations as such under this Agreement.

entitled to the benefits of Sections 2.14, 2.16, 2.20 and 9.05, as well as to
any Fees accrued for its account and not yet paid).

         (c) By executing and delivering an Assignment and Acceptance, the
assigning Lender thereunder and the assignee thereunder shall be deemed to
confirm to and agree with each other and the other parties hereto as follows:
(i) such assigning Lender warrants that it is the legal and beneficial owner of
the interest being assigned thereby free and clear of any adverse claim and that
its Commitment, and the outstanding balances of its Revolving Loans and
Competitive Loans, in each case without giving effect to assignments thereof
<PAGE>
                                       40

which have not become effective, are as set forth in such Assignment and
Acceptance, (ii) except as set forth in (i) above, such assigning Lender makes
no representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with this
Agreement, or the execution, legality, validity, enforceability, genuineness,
sufficiency or value of this Agreement or any other instrument or document
furnished pursuant hereto, or the financial condition of the Borrower or any
Subsidiary or the performance or observance by the Borrower or any Subsidiary of
any of its obligations under this Agreement or any other instrument or document
furnished pursuant hereto; (iii) such assignee represents and warrants that it
is legally authorized to enter into such Assignment and Acceptance; (iv) such
assignee confirms that it has received a copy of this Agreement, together with
copies of the most recent financial statements referred to in Section 3.05 or
delivered pursuant to Section 5.04 and such other documents and information as
it has deemed appropriate to make its own credit analysis and decision to enter
into such Assignment and Acceptance; (v) such assignee will independently and
without reliance upon the Administrative Agent, such assigning Lender or any
other Lender and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under this Agreement; (vi) such assignee appoints and
authorizes the Administrative Agent to take such action as agent on its behalf
and to exercise such powers under this Agreement as are delegated to the
Administrative Agent by the terms hereof, together with such powers as are
reasonably incidental thereto; and (vii) such assignee agrees that it will
perform in accordance with their terms all the obligations which by the terms of
this Agreement are required to be performed by it as a Lender.

         (d) The Administrative Agent, acting for this purpose as an agent of
the Borrower, shall maintain at one of its offices in The City of New York a
copy of each Assignment and Acceptance delivered to it and a register for the
recordation of the names and addresses of the Lenders, and the Commitment of,
and principal amount of the Loans owing to, each Lender pursuant to the terms
hereof from time to time (the "Register"). The Borrower, the Administrative
Agent and the Lenders may treat each person whose name is recorded in the
Register pursuant to the terms hereof as a Lender hereunder for all purposes of
this Agreement, notwithstanding notice to the contrary, and such entries in the
Register shall be conclusive absent manifest error. The Register shall be
available for inspection by the Borrower and any Lender, at any reasonable time
and from time to time upon reasonable prior notice.

         (e) Upon its receipt of a duly completed Assignment and Acceptance
executed by an assigning Lender and an assignee, an Administrative Questionnaire
completed in respect of the assignee (unless the assignee shall already be a
Lender hereunder), the processing and recordation fee referred to in paragraph
(b) above and, if required, the written consent of the Borrower and the
Administrative Agent to such assignment, the Administrative Agent shall (i)
accept such Assignment and Acceptance, (ii) record the information contained
therein in the Register and (iii) give prompt notice thereof to the Lenders and
the Borrower. No assignment shall be effective unless it has been recorded in
the Register as provided in this paragraph (e).

         (f) Each Lender may without the consent of the Borrower or the
Administrative Agent sell participations to one or more banks or other entities
in all or a portion of its rights and obligations under this Agreement
(including all or a portion of its Commitment and the Loans owing to it);
provided, however, that (i) such Lender's obligations under this Agreement shall
remain unchanged, (ii) such Lender shall remain solely responsible to the other
parties hereto for the performance of such obligations, (iii) the
participating banks or other entities shall be entitled to the benefit of the
cost protection provisions contained in Sections 2.14, 2.16 and 2.20 (and shall
have the duty to mitigate under Section 2.21) to the same extent as if they were
Lenders and (iv) the Borrower, the Administrative Agent and the Lenders shall
continue to deal solely and directly with such Lender in connection with such
Lender's rights and obligations under this Agreement, and such Lender shall
retain the sole right to enforce the obligations of the Borrower relating to the
Loans and to approve any amendment, modification or waiver of any provision of
this Agreement (other than amendments, modifications or waivers decreasing any
fees payable hereunder or the amount of principal of or the rate at which
interest is payable on the Loans, extending any scheduled principal payment date
or date fixed for the payment of interest on the Loans or increasing or
extending the Commitments).


<PAGE>
                                       41

         (g) Any Lender or participant may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this Section
9.04, disclose to the assignee or participant or proposed assignee or
participant any information relating to the Borrower furnished to such Lender by
or on behalf of the Borrower; provided that, prior to any such disclosure of
information designated by the Borrower as confidential, "Company Private" or
"Proprietary", each such assignee or participant or proposed assignee or
participant shall execute an agreement whereby such assignee or participant
shall agree (subject to customary exceptions) to preserve the confidentiality of
such confidential information on terms no less restrictive than those applicable
to the Lenders pursuant to Section 9.16.

         (h) Any Lender may at any time assign all or any portion of its rights
under this Agreement to a Federal Reserve Bank to secure extensions of credit by
such Federal Reserve Bank to such Lender; provided that no such assignment shall
release a Lender from any of its obligations hereunder or substitute any such
Bank for such Lender as a party hereto. In order to facilitate such an
assignment to a Federal Reserve Bank, the Borrower shall, at the request of the
assigning Lender, duly execute and deliver to the assigning Lender a promissory
note or notes evidencing the Loans made to the Borrower by the assigning Lender
hereunder.

         (i) The Borrower shall not assign or delegate any of its rights or
duties hereunder without the prior written consent of the Administrative Agent
and each Lender, and any attempted assignment without such consent shall be null
and void.

         (j) Notwithstanding anything to the contrary contained herein, any
Lender (a "Granting Lender") may grant to a special purpose funding vehicle (an
"SPC") of such Granting Lender, identified as such in writing from time to time
by the Granting Lender to the Administrative Agent and the Borrower, the option
to provide to the Borrower all or any part of any Loan that such Granting Lender
would otherwise be obligated to make to the Borrower pursuant to Section 2.01 or
2.03(e), provided that (i) nothing herein shall constitute a commitment to make
any Loan by any SPC and (ii) if an SPC elects not to exercise such option or
otherwise fails to provide all or any part of such Loan, the Granting Lender
shall be obligated to make such Loan pursuant to the terms hereof. The making of
a Loan by an SPC hereunder shall utilize the Commitment of the Granting Lender
(and, if such Loan is a Competitive Loan, shall be deemed to utilize the
Commitments of all the Lenders) to the same extent, and as if, such Loan were
made by the Granting Lender. Each party hereto hereby agrees that no SPC shall
be liable for any indemnity or similar payment obligation under this Agreement
(all liability for which shall remain with the related Granting Lender). In
furtherance of the foregoing, each party hereto hereby agrees (which agreement
shall survive the termination of this Agreement) that, prior to the date that is
one year and one day after the payment in full of all outstanding senior
indebtedness of any SPC, it will not institute against, or join any other person
in instituting against, such SPC any bankruptcy, reorganization, arrangement,
insolvency or liquidation proceedings or similar proceedings under the laws of
the United States or any State thereof. In addition, notwithstanding anything to
the contrary contained in this Section 9.04 or in Section 9.16, any SPC may (i)
with notice to, but without the prior written consent of, the Borrower or the
Administrative Agent and without paying any processing fee therefor, assign all
or a portion of its interests in any Loans to its Granting Lender or to any
financial institutions providing liquidity and/or credit facilities to or for
the account of such SPC to fund the Loans made by such SPC or to support
the securities (if any) issued by such SPC to fund such Loans and (ii) disclose
on a confidential basis any non-public information relating to its Loans to any
rating agency, commercial paper dealer or provider of a surety, guarantee or
credit or liquidity enhancement to such SPC.

         SECTION 9.05. Expenses; Indemnity. (a) The Borrower agrees to pay all
out-of-pocket expenses incurred by the Agents in connection with the syndication
of the credit facilities provided for herein and the preparation and
administration of this Agreement or in connection with any amendments,
modifications or waivers of the provisions hereof (whether or not the
transactions hereby or thereby contemplated shall be consummated) or incurred by
the Administrative Agent or any Lender in connection with the enforcement or
protection of its rights in connection with this Agreement or in connection with
the Loans made hereunder, including the reasonable fees, charges and
disbursements of Cravath, Swaine & Moore, counsel for the Administrative Agent,
and, in connection with any such enforcement or protection, the reasonable fees,
charges and disbursements of any other counsel (including the allocated charges
of in-house counsel) for the Administrative Agent or any Lender. The Borrower
shall not be obligated to reimburse out-of-pocket legal expenses pursuant to the
preceding sentence for more than one law firm for the Agents incurred in
connection with the preparation of this Agreement or in connection with any
particular amendment, modification or waiver of the provisions hereof.
<PAGE>
                                       42

         (b) The Borrower agrees to indemnify the Administrative Agent and each
Lender, each Affiliate of any of the foregoing persons and each of their
respective directors, officers, employees and agents (each such person being
called an "Indemnitee") against, and to hold each Indemnitee harmless from, any
and all losses, claims, damages, liabilities and related expenses, including
reasonable counsel fees, charges and disbursements, incurred by or asserted
against any Indemnitee arising out of, in any way connected with, or as a result
of (i) the execution or delivery of this Agreement or any agreement or
instrument contemplated thereby, the performance by the parties thereto of their
respective obligations thereunder or the consummation of the Transactions and
the other transactions contemplated hereby, (ii) the use of the proceeds of the
Loans or (iii) any claim, litigation, investigation or proceeding relating to
any of the foregoing, whether or not any Indemnitee is a party thereto; provided
that such indemnity shall not, as to any Indemnitee, be available to the extent
that such losses, claims, damages, liabilities or related expenses result from
the gross negligence or wilful misconduct of such Indemnitee.

         (c) The provisions of this Section 9.05 shall remain operative and in
full force and effect regardless of the expiration of the term of this
Agreement, the consummation of the transactions contemplated hereby, the
repayment of any of the Loans, the expiration of the Commitments, the invalidity
or unenforceability of any term or provision of this Agreement, or any
investigation made by or on behalf of the Administrative Agent or any Lender.
All amounts due under this Section 9.05 shall be payable on written demand
therefor.

         SECTION 9.06. Right of Setoff. If an Event of Default shall have
occurred and be continuing, each Lender is hereby authorized at any time and
from time to time, to the fullest extent permitted by law, to set off and apply
any and all deposits (general or special, time or demand, provisional or final)
at any time held and other indebtedness at any time owing by such Lender to or
for the credit or the account of the Borrower against any of and all the
obligations of the Borrower now or hereafter existing under this Agreement held
by such Lender, irrespective of whether or not such Lender shall have made any
demand under this Agreement and although such obligations may be unmatured. The
rights of each Lender under this Section are in addition to other rights and
remedies (including other rights of setoff) which such Lender may have.

         SECTION 9.07.  APPLICABLE LAW.  THIS AGREEMENT SHALL BE CONSTRUED
IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

         SECTION 9.08.  Waivers; Amendment.  (a)  No failure or delay of the
Administrative Agent or any Lender in exercising any power or right hereunder
shall operate as a waiver thereof, nor shall any single or partial exercise of
any such right or power, or any abandonment or discontinuance of steps to 
enforce such a right or power, preclude any other or further exercise
thereof or the exercise of any other right or power. The rights and remedies of
the Administrative Agent and the Lenders hereunder are cumulative and are not
exclusive of any rights or remedies that they would otherwise have. No waiver of
any provision of this Agreement or consent to any departure by the Borrower
therefrom shall in any event be effective unless the same shall be permitted by
paragraph (b) below, and then such waiver or consent shall be effective only in
the specific instance and for the purpose for which given. No notice or demand
on the Borrower in any case shall entitle the Borrower to any other or further
notice or demand in similar or other circumstances.

         (b) Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to an agreement or agreements in writing
entered into by the Borrower and the Required Lenders; provided, however, that
no such agreement shall (i) decrease the principal amount of, or extend the
maturity of or any scheduled principal payment date or date for the payment of
any interest on any Loan or the payment of any Facility Fee, or waive or excuse
any such payment or any part thereof, or decrease the rate of interest on any
Loan, without the prior written consent of each Lender affected thereby, (ii)
change or extend the Commitment or decrease the Facility Fees of any Lender
without the prior written consent of such Lender, or (iii) amend or modify the
provisions of Section 2.17, the provisions of Section 9.04(i), the provisions of
this Section or the definition of the term "Required Lenders", without the prior
written consent of each Lender; provided further that no such agreement shall
amend, modify or otherwise affect the rights or duties of the Administrative
Agent hereunder without the prior written consent of the Administrative Agent.
<PAGE>
                                       43

         SECTION 9.09. Interest Rate Limitation. Notwithstanding anything herein
to the contrary, if at any time the interest rate applicable to any Loan,
together with all fees, charges and other amounts which are treated as interest
on such Loan under applicable law (collectively the "Charges"), shall exceed the
maximum lawful rate (the "Maximum Rate") which may be contracted for, charged,
taken, received or reserved by the Lender holding such Loan in accordance with
applicable law, the rate of interest payable in respect of such Loan hereunder,
together with all Charges payable in respect thereof, shall be limited to the
Maximum Rate and, to the extent lawful, the interest and Charges that would have
been payable in respect of such Loan but were not payable as a result of the
operation of this Section shall be cumulated and the interest and Charges
payable to such Lender in respect of other Loans or periods shall be increased
(but not above the Maximum Rate therefor) until such cumulated amount, together
with interest thereon at the Federal Funds Effective Rate to the date of
repayment, shall have been received by such Lender.

         SECTION 9.10. Entire Agreement. This Agreement and the Fee Letter
constitute the entire contract among the parties relative to the subject matter
hereof. Any other previous agreement among the parties with respect to the
subject matter hereof is superseded by this Agreement. Nothing in this
Agreement, expressed or implied, is intended to confer upon any party other than
the parties hereto and thereto any rights, remedies, obligations or liabilities
under or by reason of this Agreement.

         SECTION 9.11. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY
IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT
IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR
INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT. EACH
PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY
OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD
NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B)
ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER
INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND
CERTIFICATIONS IN THIS SECTION 9.11.

         SECTION 9.12. Severability. In the event any one or more of the
provisions contained in this Agreement should be held invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained herein and therein shall not in any way be
affected or impaired thereby. The parties shall endeavor in good-faith
negotiations to replace the invalid, illegal or unenforceable provisions with
valid provisions the economic effect of which comes as close as possible to that
of the invalid, illegal or unenforceable provisions.
<PAGE>
                                       44

         SECTION 9.13. Counterparts. This Agreement may be executed in
counterparts (and by different parties hereto on different counterparts), each
of which shall constitute an original but all of which when taken together shall
constitute a single contract, and shall become effective as provided in Section
9.03. Delivery of an executed signature page to this Agreement by facsimile
transmission shall be effective as delivery of a manually signed counterpart of
this Agreement.

         SECTION 9.14. Headings. Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of this
Agreement and are not to affect the construction of, or to be taken into
consideration in interpreting, this Agreement.

         SECTION 9.15. Jurisdiction; Consent to Service of Process. (a) The
Borrower hereby irrevocably and unconditionally submits, for itself and its
property, to the nonexclusive jurisdiction of any New York State court or
Federal court of the United States of America sitting in New York City, and any
appellate court from any thereof, in any action or proceeding arising out of or
relating to this Agreement, or for recognition or enforcement of any judgment,
and each of the parties hereto hereby irrevocably and unconditionally agrees
that all claims in respect of any such action or proceeding may be heard and
determined in such New York State or, to the extent permitted by law, in such
Federal court. Each of the parties hereto agrees that a final judgment in any
such action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.
Nothing in this Agreement shall affect any right that the Administrative Agent
or any Lender may otherwise have to bring any action or proceeding relating to
this Agreement against the Borrower or its properties in the courts of any
jurisdiction.

         (b) The Borrower hereby irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, any objection which it may
now or hereafter have to the laying of venue of any suit, action or proceeding
arising out of or relating to this Agreement in any New York State or Federal
court. Each of the parties hereto hereby irrevocably waives, to the fullest
extent permitted by law, the defense of an inconvenient forum to the maintenance
of such action or proceeding in any such court.

         (c) Each party to this Agreement irrevocably consents to service of
process in the manner provided for notices in Section 9.01. Nothing in this
Agreement will affect the right of any party to this Agreement to serve process
in any other manner permitted by law.

         SECTION 9.16. Confidentiality. The Administrative Agent and each of the
Lenders agrees to keep confidential (and to use its best efforts to cause its
respective agents and representatives to keep confidential) the Information (as
defined below) and all copies thereof, extracts therefrom and analyses or other
materials based thereon, except that the Administrative Agent or any Lender
shall be permitted to disclose Information (a) to such of its respective
officers, directors, employees, agents, affiliates and representatives as need
to know such Information, (b) to the extent requested by any regulatory
authority or examining authority, (c) to the extent otherwise required by
applicable laws and regulations or by any subpoena or similar legal process, (d)
in connection with any suit, action or proceeding relating to the enforcement of
its rights hereunder, (e) to the extent permitted by Section 9.04(g), or (f) to
the extent such Information (i) becomes publicly available other than as a
<PAGE>
                                       45

result of a breach of this Agreement or (ii) becomes available to the
Administrative Agent or any Lender on a nonconfidential basis from a source
other than the Borrower. For the purposes of this Section, "Information" shall
mean all financial statements, certificates, reports, agreements and information
(including all analyses, compilations and studies prepared by the Administrative
Agent or any Lender based on any of the foregoing) that are received from the
Borrower or any Subsidiary and related to the Borrower, any Subsidiary or any
employee, customer or supplier of the Borrower, other than any of the foregoing
that were available to the Administrative Agent or any Lender on a
nonconfidential basis prior to its disclosure thereto by the Borrower, and 
which are in the case of Information provided after the date hereof, clearly 
identified at the time of delivery as confidential, "Company Private" or 
"Proprietary". The provisions of this Section 9.16 shall remain operative and in
full force and effect regardless of the expiration and term of this Agreement.


         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
duly executed by their respective authorized officers as of the day and year
first above written.
