        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
                             (DOLLARS IN THOUSANDS)

NOTE 1. BASIS OF PRESENTATION


In the opinion of management, the accompanying condensed consolidated financial
statements contain all adjustments necessary to present fairly the company's
financial position at July 2, 1999 and December 25, 1998, the results of its
operations, and its cash flows for the six months ended July 2, 1999 and June
26, 1998, such adjustments being of a normal recurring nature. Operating results
for the quarter and six months ended July 2, 1999 are not necessarily indicative
of the results that may be expected for the fiscal year ended December 31, 1999.

American Commercial Lines LLC ("ACL") was a wholly owned subsidiary of CSX
Corporation ("CSX") until June 30, 1998. On June 30, 1998 ACL's parent, American
Commercial Lines Holdings LLC (the "Parent"), completed a recapitalization in a
series of transactions in which the barge business of Vectura Group, Inc.
("Vectura") and its subsidiaries ("NMI" or the "NMI Contribution") were combined
with that of ACL. ACL issued $735 million in new debt in connection with these
transactions. These transactions were accounted for as a recapitalization of ACL
and the NMI Contribution was recorded by the purchase method of accounting. The
results of the NMI operations and cash flows are included in the accompanying
financial statements since June 30, 1998.

ACL was reorganized as a limited liability company in the second quarter of
1998. As such, ACL passes through its U.S. federal and state (but not foreign)
taxable income to its member who is responsible for income taxes on such taxable
income. All of ACL's corporate subsidiaries were converted to limited liability
companies (except for ACL Capital Corp. and the foreign subsidiaries) on June
30, 1998 prior to the recapitalization.

While management believes that the disclosures presented are adequate to make
the information not misleading, it is suggested that these condensed
consolidated financial statements be read in conjunction with the 1998 audited
consolidated financial statements and the notes related thereto included in
ACL's Form 10-K.

ACL's fiscal year ends on the last Friday in December. The condensed
consolidated financial statements presented are for the 13 and 27 weeks ended
July 2, 1999 and the 13 and 26 weeks ended June 26, 1998, and the fiscal year
(52 weeks) ended December 25, 1998.

NOTE 4. SUPPLEMENTAL DISCLOSURE OF CASH FLOW INFORMATION

ACL had unpaid property additions of $11,033 at July 2, 1999 recorded as Other
Current Liabilities. Payments were made in July 1999.

NOTE 5. CONTINGENCIES

A number of legal actions are pending against ACL in which claims are made in
substantial amounts. While the ultimate results of pending litigation cannot be
predicted with certainty, management does not currently expect that resolution
of these matters will have a material adverse effect on the consolidated results
of operations, financial position and cash flows.

NOTE 6. CHANGES IN ACCOUNTING STANDARDS

In December 1997, the AICPA issued Statement of Position No. 97-3, "Accounting
by Insurance and Other Enterprises for Insurance-Related Assessments" (SOP 97-3)
which provides guidance on recognition, measurement, and disclosure of
liabilities for guaranty-fund and certain other insurance-related assessments,
including workers' compensation second-injury funds. SOP 97-3 is effective for
fiscal years beginning after December 15, 1998. ACL adopted SOP 97-3 in the
first quarter of 1999, with a cumulative effect adjustment of $1,737 in non-cash
expense.

NOTE 7. GUARANTOR FINANCIAL STATEMENTS

The $735 million of debt issued by ACL and a revolving credit facility, which
provides for revolving loans and the issuance of letters of credit in an
aggregate amount up to $100 million, are guaranteed by ACL's wholly-owned
domestic subsidiaries, other than ACL Capital Corp. (which was formed in
connection with the transaction), any Accounts Receivable Subsidiary (as defined
in the Indentures with respect to such debt) and certain subsidiaries of ACL
without substantial assets or operations (collectively the "Subsidiary
Guarantors"). Such guarantees are full, unconditional and joint and several.
Separate financial statements of the Subsidiary Guarantors are not presented
because management has determined that they would not be material to investors.
The following supplemental financial information sets forth on a combined basis,
combining statements of financial position, statements of earnings and
statements of cash flows for the Subsidiary Guarantors, non-guarantor
subsidiaries and for ACL as of July 2, 1999 and December 25, 1998 and the
quarters and six months ended July 2, 1999 and June 26, 1998.

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

OVERVIEW

American Commercial Lines LLC ("ACL") is an integrated marine transportation and
service company, providing barge transportation services on the inland waterways
of North and South America. ACL supports its barging operations by providing
towboat and barge design and construction, terminal services and ship-to-shore
voice and data telecommunications services to its subsidiary companies and third
parties.

ACL was a wholly owned subsidiary of CSX Corporation ("CSX") until June 30,
1998. On June 30, 1998, ACL's parent, American Commercial Lines Holdings LLC
("Parent"), completed a recapitalization in a series of transactions in which
the barge business of Vectura Group, Inc. ("Vectura"), consisting of National
Marine, Inc. ("National Marine") and its subsidiaries, was combined with that of
ACL (the "Recapitalization"). ACL issued $735 million in new debt in connection
with these transactions.

ACL integrated National Marine's operations into its operations in the third
quarter of 1998, increasing its total barge fleet by approximately 16% with the
liquid and dry cargo barge fleets increasing by 82% and 11%, respectively.


RESULTS OF OPERATIONS

QUARTER ENDED JULY 2, 1999 COMPARED WITH QUARTER ENDED JUNE 26, 1998

OPERATING REVENUE. Operating revenue for the quarter ended July 2, 1999,
increased 27% to $190.0 million from $150.0 million for the second quarter of
1998. The revenue increase was primarily due to increased volumes resulting from
the combination of National Marine's barging operations with those of ACL and
higher sales at Jeffboat, ACL's marine construction subsidiary.

Domestic barging revenue increased $32.7 million to $133.2 million primarily due
to increased volumes as a result of the larger fleet. This increase was
partially offset by adverse operating conditions in late April. Heavy rains
contributed to high water on the upper Mississippi River, resulting in delays
and smaller tow sizes. Domestic spot grain rates were higher in the second
quarter of 1999 compared to 1998 due to increased demand for U.S. grain exports.
Revenue at Jeffboat rose $6.6 million to $36.1 million, reflecting significantly
higher sales of hopper barges to third-party customers. International barging
revenues increased $1.9 million to $15.3 million, primarily due to higher
volumes at ACBL de Venezuela ("ACBLV") where navigation on the river system
began earlier in the second quarter of 1999 than it did in 1998.

OPERATING EXPENSE. Operating expense for the quarter increased 22% to $170.0
million from $138.9 million in the same quarter last year. The increase in
expenses was largely due to higher domestic barging volumes and increased
production at Jeffboat. Domestic barging expenses rose $30.1 million to $121.8
million, primarily due to increased volumes from the larger fleet size but also
because of adverse operating conditions resulting from high water on the upper
Mississippi River in April. Fuel prices were slightly lower in the second
quarter of 1999 compared to 1998. Jeffboat's expenses rose $6.3 million to $32.6
million due to higher volumes. International barging expenses decreased $0.8
million to $11.6 million, primarily due to decreases at ACBL Hidrovias
("ACBLH"), which operates along the Parana/Paraguay River system, because of
start-up costs incurred in 1998. Expenses decreased slightly at ACBLV where
increases due to volume were more than offset by decreases resulting from
releasing some barge charters in the second quarter of 1999. Elimination of the
CSX corporate management fee pursuant to the Recapitalization reduced second
quarter 1999 expenses by $3.7 million compared to 1998.

OPERATING INCOME. Operating income for the quarter rose 78% to $20.0 million
from $11.2 million for the same period in 1998 due to the foregoing factors.

INTEREST EXPENSE. Interest expense for the quarter increased to $17.0 million
from $3.3 million for the same period in 1998. The increase is due to $735
million of long-term debt secured for ACL's recapitalization.

                                      17
<PAGE>

EARNINGS BEFORE INCOME TAXES. Earnings before income taxes were $3.0 million in
the 1999 quarter compared with $7.1 million for the same period in 1998 due to
the reasons discussed above.

INCOME TAXES (BENEFIT). Income taxes for the quarter increased to an expense of
$0.2 million compared to a benefit of $64.8 million for last year's quarter. ACL
was converted to a limited liability company in the second quarter of 1998. Due
to the change in tax status, previously recognized deferred income taxes were
reversed resulting in a benefit of approximately $65 million. ACL passes its
U.S. federal and state taxable income to its Parent whose equity holders are
responsible for income taxes.

NET EARNINGS.  Net earnings for the quarter were $2.8 million  compared to $72.0
million for the same period in 1998, due to the foregoing factors.


SIX MONTHS ENDED JULY 2, 1999 COMPARED WITH SIX MONTHS ENDED JUNE 26, 1998

ACL follows a 52/53-week fiscal year ending on the last Friday in December of
each year. 1999 is a 53-week year. The six months ended July 2, 1999 consisted
of 27 weeks, compared with 26 weeks in the six months ended June 26, 1998. The
additional week in 1999 was in the first quarter.

OPERATING REVENUE. Operating revenue for the six months ended July 2, 1999,
increased 36% to $363.2 million from $266.9 million for the six months of 1998.
The revenue increase was due to increased volumes resulting from the combination
of National Marine's barging operations with those of ACL, higher sales at
Jeffboat and the additional week during the first quarter of 1999.

Domestic barging revenue increased $63.6 million to $262.5 million primarily due
to increased volumes resulting from the larger fleet and the additional week in
the first quarter. These increases were partially offset by difficult operating
conditions in both quarters of 1999. Severe ice forced the closure of the
Illinois River for two weeks early in the first quarter and high water on the
upper Mississippi River early in the second quarter resulted in delays and
reduced tow sizes. Domestic rates for the six-month period in 1999 remained
relatively constant compared with the same period in 1998. Rates in the first
quarter of 1999 were slightly lower than 1998 primarily due to adjustments to
contract prices to reflect lower fuel prices but rates were higher in the second
quarter of 1999 as spot grain rates increased due to increased demand for U.S.
grain exports. Revenue at Jeffboat rose $31.0 million to $68.4 million,
reflecting significantly higher sales of hopper barges to third-party customers
and more favorable weather conditions in the first quarter of 1999 compared to
1998. International revenues increased $3.1 million to $20.5 million, primarily
due to higher volumes at ACBLV where navigation on the river system began
earlier in the second quarter of 1999 than it did in 1998.

OPERATING EXPENSE. Operating expense for the six months increased 36% to $338.9
million from $249.7 million in the same quarter last year. The higher expenses
were due largely to higher domestic barging volumes, increased sales at
Jeffboat, adverse operating conditions in both quarters of 1999 and the
additional week in the first quarter. Domestic barging expenses rose $68.5
million to $247.8 million, primarily due to increased volumes from the larger
fleet size and the additional week but also because of the adverse operating
conditions in both quarters. Fuel prices in the first six months of 1999 were
lower than the same period last year, decreasing from 49 cents per gallon in
1998 to 42 cents per gallon in 1999. Jeffboat's expenses rose $28.4 million to
$61.5 million due to significantly higher volumes. International barging
expenses increased $1.3 million to $21.5 million primarily due to increased
volumes at ACBLV, partially offset by lower costs at ACBLH due to start-up costs
in 1998. Elimination of the CSX corporate management fee pursuant to the
Recapitalization reduced 1999 expenses by $7.4 million.

OPERATING INCOME.  Operating income for the six months rose 41% to $24.3 million
from $17.2 million for the same period in 1998 due to the foregoing factors.

                                      18

<PAGE>

INTEREST EXPENSE. Interest expense for the six months increased to $35.6 million
from $6.1 million for the same period in 1998. The increase is due to $735
million of long-term debt secured for ACL's recapitalization.

OTHER, NET. Other income for the six month period was $1.4 million compared to
an expense of $0.7 million for the same period in 1998. The decrease was
primarily due to higher interest income and increased earnings from a joint
venture with an unconsolidated third-party which owns and operates terminal
facilities.

EARNINGS (LOSS) BEFORE INCOME TAXES. Earnings (loss) before income taxes and
before the cumulative effect of an accounting change was a loss of $10.0 million
in the 1999 six month period compared with earnings of $10.4 million for the
same period in 1998 due to the reasons discussed above.

INCOME TAXES (BENEFIT). Income taxes for the six months increased to an expense
of $0.1 million from a benefit of $62.2 million for last year's six month
period. ACL was converted to a limited liability company in the second quarter
of 1998. Due to the change in tax status, previously recognized deferred tax
liabilities were reversed in the second quarter of 1998. ACL passes its U.S.
federal and state taxable income to its Parent whose equity holders are
responsible for income taxes.

CUMULATIVE EFFECT OF ACCOUNTING CHANGE. In the first quarter of 1999, ACL
adopted AICPA Statement of Position 97-3, "Accounting by Insurance and Other
Enterprises for Insurance-Related Assessments." Implementing the new accounting
rule, which applies to workers compensation second-injury fund assessments,
resulted in a non-cash, cumulative-effect adjustment of $1.7 million in the
first quarter of 1999.

NET (LOSS) EARNINGS. Net (loss) earnings for the six months was a loss of $11.8
million compared with earnings of $72.7 million for the same period in 1998, due
to the foregoing factors.

OUTLOOK

Management expects the domestic barging demand and spot rates for grain, bulk
and steel to continue to improve in the second half of 1999 compared with 1998
levels. The U.S. Department of Agriculture currently forecasts 1999 corn exports
of 1.925 billion bushels, an increase of 425 million bushels over 1998 levels.
However, two locks on the upper Mississippi River will temporarily be closed for
repair in July and August. Delays are expected to negatively impact domestic
barging results in the third quarter. Low water resulting from extreme heat in
July may also negatively impact domestic barging results in the third quarter.

LIQUIDITY AND CAPITAL RESOURCES

In connection with the Recapitalization, ACL incurred $735 million in long-term
debt consisting of two term loans in the principal amount of $435 million, a
revolving credit facility and the issuance of letters of credit in an aggregate
amount up to $100 million (the "Senior Credit Facilities"), and $300 million in
Senior Notes (the "Senior Notes"). Prior to the Recapitalization, ACL
participated in CSX's cash management plan, through which most of its cash needs
were funded by CSX and any excess cash was advanced to CSX for investment.

The Senior Credit Facilities and the Senior Notes contain a number of covenants
with specified financial ratios and tests including, with respect to the Senior
Credit Facilities, maximum leverage ratios and minimum interest coverage ratios.
A failure to maintain specified financial ratios could lead to an event of
default which could result in acceleration of the debt, higher interest rates or
other adverse consequences. Compliance with financial ratios is measured at the
end of each quarter. ACL's ability to meet financial ratios is affected by
adverse weather conditions, seasonality and other risk factors inherent in its
business.

Cash totaled $38.7 million at July 2, 1999, and there were no loans outstanding
under the revolving credit facility. Cash generated from operations totaled
$13.9 million in the first six months of 1999 compared with $12.7 million in the
first six months of 1998. ACL acquired 60 used barges for $11.3 million at the
end of the second quarter of 1999 with payment made early in the third quarter.

Management believes that cash generated from operations together with the
borrowings available under the revolving credit facility are more than
sufficient to fund its cash requirements, including capital expenditures for

                                      19

<PAGE>

fleet replacement, maintenance and expansion, working capital, interest payments
and scheduled principal payments.

Capital expenditures for 1999 are projected to be $65 million.  As of July 2,
1999, $34.1 million had been incurred.


YEAR 2000

OVERVIEW

ACL formed a Year 2000 project team in mid-1997 to identify information
technology and non-information technology systems that require modification for
the Year 2000. Over the past two years, ACL has developed, upgraded and replaced
certain systems to meet its core business requirements, with the additional
benefit of achieving Year 2000 compliance for those systems. ACL's current Year
2000 effort encompasses all functions and operations of ACL, including those of
American Commercial Barge Line (domestic barging); Jeffboat (shipyards),
American Commercial Terminals (marine terminals); Louisiana Dock Company (marine
services); American Commercial Lines International (international barging and
marine services); and Waterway Communications System (marine
telecommunications).

SCOPE OF YEAR 2000 EFFORT

The scope of this effort includes all hardware, software and mission critical
business processes. This includes, but is not limited to, mainframe and client
server systems, desktop applications and spreadsheets, mainframe and personal
computer hardware, voice and data communications networks, embedded systems,
electronic interfaces, suppliers, customers, utilities, government agencies,
financial institutions and others. ACL's focus throughout this process has
remained on mission critical systems, trading partners and other third parties
which have been identified as strategically important or necessary to continue
its business into the new millenium.

The Year 2000 project team has representatives from senior management and key
areas of the company's operations. The team provides overall guidance and
coordination of the project. ACL's senior management and the Board of Managers
monitor this effort through periodic status reports.


STATUS OF YEAR 2000 EFFORT

Management believes that ACL has materially completed it preparations for the
Year 2000, with the exception of ongoing testing and assessment of third-party
Year 2000 readiness status.

The remediation of ACL's mainframe and client server systems is materially
complete. Further documentation of test plans was completed in April 1999 and
testing of mission critical mainframe and client server computer systems was
materially completed in July 1999 with such testing to continue through 1999, if
necessary. Testing and replacement, as needed, of personal computer ("PC")
hardware and software was materially completed in July 1999. ACL also completed
review and remediation of material PC-resident spreadsheets in July 1999.

ACL also has completed its assessment of key operating assets, facilities and
telecommunications networks for embedded technology. This assessment includes
marine terminal operations and vessel systems such as electronic navigation
equipment, diesel engine monitoring systems and other emergency monitors and
alarms. ACL currently anticipates no material impairment of its operations due
to embedded technology that cannot be addressed by remediation or contingency
planning.

As part of its Year 2000 project, ACL is in communication with its mission
critical suppliers, larger customers and financial institutions and other
significant third parties to assess their Year 2000 readiness. ACL has conducted
an initial survey of these key trading partners and has assessed, to the best of
its ability, whether key trading partners are addressing their Year 2000 issues
appropriately. Although initial assessments and more thorough audits, as called
for, have been conducted, ACL will continue its assessment of third-party
readiness throughout 1999. Further, risks associated with any such third parties
located outside the United States may be higher insofar as it is

                                      20

<PAGE>

generally believed that non-U.S. businesses may not be addressing their Year
2000 issues on as timely a basis as are U.S. businesses.

CONTINGENCY PLANS

ACL has assessed the consequences of Year-2000-related failures in third-party
services and in any remediation effort not being successful, among other things,
and has planned for contingencies, including efforts to address disruptions in
third-party services, such as telecommunications and electricity, on which its
systems and operations rely. The contingency plans include plans for securing
alternate or replacement suppliers for goods and/or services and developing
other strategic solutions for mission critical areas should the need arise. In
addition, ACL has contingency plans in place on its vessels and at its
facilities in the event a Year 2000-related computer system failure causes
system or equipment shut down. ACL's contingency plans will be reviewed
throughout the year and revised, as necessary, as business conditions and
outlooks change.

ACL presently anticipates that its greatest exposure for Year 2000 problems may
result from telecommunication, utility or financial institution failures; rail
service or other equipment failures that hinder loading or unloading at marine
terminals; failures of fuel or other key suppliers, and failures of locks or
dams that impact river navigation by ACL vessels. Contingency plans have been
prepared to address these and other areas of significant risk. However, there
can be no assurances that ACL's contingency plans or its efforts with respect to
third parties will prevent a material adverse effect on its business, results of
operations or financial condition.

COST OF YEAR 2000 PROJECT

ACL has spent $1.9 million to date, related to this project. The remaining cost
of the Year 2000 project is presently estimated at $1.4 million, which will be
expensed as incurred through 2000. The total estimated cost of $3.3 million will
comprise approximately 16% of ACL's total technology budget for the project
period and includes $2.3 million to upgrade and replace software and $1.0
million for hardware. A portion of the total Year 2000 project expense is
represented by existing staff that has been or will be deployed to this project.
ACL has also engaged consultants and contractors to assist in its Year 2000
efforts.

ACL does not believe that the redeployment of existing staff has had or will
have a material adverse effect on its business, results of operations or
financial position. However, the remaining cost and the date on which ACL
believes it will complete the Year 2000 project are based on management's
current estimates, which are derived utilizing numerous assumptions of future
events, including the continued availability of certain staff resources, and are
inherently uncertain.


CHANGES IN ACCOUNTING STANDARDS

In December 1997, the AICPA issued Statement of Position No. 97-3, "Accounting
by Insurance and Other Enterprises for Insurance-Related Assessments" (SOP 97-3)
which provides guidance on recognition, measurement, and disclosure of
liabilities for guaranty-fund and certain other insurance-related assessments,
including workers' compensation second-injury funds. SOP 97-3 is effective for
fiscal years beginning after December 15, 1998. ACL adopted SOP 97-3 in the
first quarter of 1999, with a cumulative effect adjustment of $1.7 million in
non-cash expense.

shall be deemed to have been effected as of the close of business on the date on
which such notice has been received by the Company, and at such time such Class
B Common Units shall be deemed to have been canceled and converted into Class A
Common Units, and at such time the Class A Common Units, issuable upon such
conversion shall be deemed to be issued.  At such time, the Company shall
promptly provide written notice to all Class A Members and all Class B Members
of such conversion.

          (c)  TAXES.  The conversion of Class B Common Units into Class A
Common Units will be made without charge to the Class B Members of any stamp tax
in respect thereof, which stamp tax shall be borne by the Company.

any conversion of Class B Common Units shall, when issued, be duly and validly
issued, fully paid and non-assessable.  The

<PAGE>

Company shall take all such actions as may be necessary to assure that all
such Class A Common Units may be so issued without violation of any
applicable law or governmental regulation or any requirements of any domestic
securities exchange upon which Class A Common Units may be listed (except for
official notice of issuance which shall be immediately transmitted by the
Company upon issuance);

          (e)  COMPANY BOOKS.  The Company shall not close its books against the
Transfer of Class B Common Units or Class A Common Units in any manner that
would interfere with the timely conversion of Class B Common Units.  The Company
shall assist and cooperate in good faith with any Class B Members required to
make any governmental filings or obtain any governmental approval prior to or in
connection with any conversion of Class B Common Units hereunder (including,
without limitation, making any filings required to be made by the Company).

          (f)  SUBDIVISION.  If the Company in any manner subdivides or combines
the outstanding units of one class of Junior Common Units, the outstanding units
of the other class of Junior Common Units shall be proportionately subdivided or
combined in a similar manner.


      3.6 CONVERSION OF SENIOR PREFERRED UNITS.

          (a)  CONVERSION EVENTS.  Contemporaneously with or following any
Initial Public Offering or any other conversion of the Company into a C
Corporation, the Company may, at the option of the Board, cause all (but not
less than all) outstanding Senior Preferred Units (or Reclassified Securities
with respect thereto) to be converted into current-pay subordinated promissory
notes (the "EXCHANGE NOTES") with an initial aggregate principal amount equal to
the Senior Preferred Redemption Value outstanding at the time of such
conversion, which shall accrue interest at a rate of 11.02%, compounded
annually, and have terms that are customary for subordinated notes and otherwise
equivalent (including as to covenants and priority of distribution over the
Junior Securities and other equity securities of the Company) to the Senior
Preferred Units and otherwise in form reasonably satisfactory to the holders of
such Senior Preferred Units (or Reclassified Securities).

          (b)  NOTICE.  Each conversion of Senior Preferred Units shall be
effected by written notice by the Company to the holders of the Senior Preferred
Units stating that the Company desires to convert the Senior Preferred Units to
Exchange Notes.  Each conversion of Senior Preferred Units shall be deemed to
have been effected as of the close of business on the date on which such notice
has been received by the holders of the Senior Preferred Units, and at such time
such Senior Preferred Units shall be deemed to have been canceled and converted
into Exchange Notes, and at such time the Exchange Notes issuable upon such
conversion shall be deemed to be issued.

          (c)  TAXES.  The conversion of Senior Preferred Units into Exchange
Notes will be made without charge to the Senior Preferred Units of any stamp tax
in respect thereof, which stamp tax shall be borne by the Company.

          (d)  NO CHARGES OR VIOLATIONS.  All Exchange Notes issuable upon any
conversion of Senior Preferred Units shall, when issued, be duly and validly
issued, fully paid and non-assessable.  The Company shall take all such actions
as may be necessary to assure that all such Exchange Notes may be so issued
without violation of any applicable law or governmental regulation or any
requirements of any domestic securities exchange upon which Exchange Notes may
be listed (except for official notice of issuance which shall be immediately
transmitted by the Company upon issuance).

                           CAPITAL CONTRIBUTIONS

      4.1 INITIAL CAPITAL CONTRIBUTIONS.  Upon consummation of the transactions
contemplated by the Recapitalization Agreement, (i) the CSX Member shall be
deemed to have made to the Company (and the Company shall be deemed to have
received) a Capital Contribution in the amount of $851,352,000, (ii) Vectura
shall be deemed to have made to the Company (and the Company shall be deemed to

have received) a Capital Contribution in the amount of $3,895,000, (iv) the
Management Unitholders shall make a cash Capital Contribution in the amount of
$17,000 in the aggregate, and (v) the Investor Unitholders shall make a cash
Capital Contribution in the amount of $30,000 in the aggregate.  Immediately
following such Capital Contributions, the CSX Member shall receive a cash
distribution from the Company in the amount of $696,352,000, of which
$200,000,000 shall represent proceeds of the Senior Unsecured Notes,
$435,000,000 shall represent proceeds of the borrowings incurred as of June 30,
1998, pursuant to the Credit Agreement and $61,352,000 shall reimburse the CSX
Member for a portion of its capital expenditures incurred during the two-year
period immediately prior to June 30, 1998, with respect to property contributed
(or deemed to be contributed) to the Company as of June 30, 1998.  In exchange
for their respective Capital Contributions, the CSX Member (in addition to
receiving the cash distribution described in the preceding sentence), Vectura,
NMI, the Management Unitholders, and the Investor Unitholders shall receive and
shall be deemed to own the number of Senior Preferred Units, Junior Preferred
Units, Senior Common Units and Junior Common Units set forth opposite such
Member's name on SCHEDULE A, attached to the Prior Agreement dated as of June
30, 1998.  The Company may in its discretion issue certificates to the Members
representing the Membership Interest held by each Member.  The initial Capital
Account of each Member described above shall equal the amount of such Member's
initial aggregate Capital Contributions (reduced, in the case of the CSX Member
by the cash distribution described above), as shown on SCHEDULE A, attached to
the Prior Agreement dated as of June 30, 1998.  Except for the Capital
Contributions of the Members required to be made pursuant to this Section 4.1,
the Members shall not be required to make any additional Capital Contributions.
The Capital Contributions described in this Section 4.1 and shown on SCHEDULE A,
attached to the Prior Agreement dated as of June 30, 1998, shall be adjusted to
the extent required by Sections 2.1(j) and 2.4(c) of the Recapitalization
Agreement.

                                   ARTICLE V
                                 DISTRIBUTIONS

      5.1 IN GENERAL.  Subject to Section 9.2, any distributions of cash or
other assets by the Company to Unitholders shall be made in accordance with this
Article V.  Except to the extent otherwise provided herein, any distributions
required to be made PRO RATA to a class of Unitholders shall be made based on
their proportionate ownership of the outstanding Units within the class.
Notwithstanding any other provision hereof, the Company shall cause its
Subsidiaries to distribute to the Company, to the full extent possible within
the limits imposed by Applicable Law, the Credit Agreement and Senior Unsecured
Debt Documents, the cash or cash equivalents necessary for the Company to make
the distributions required hereunder.

      5.2 DISCRETIONARY DISTRIBUTIONS.

          (a)  Subject to Sections 5.2(b), 5.3, 5.4, 5.5 and 9.2, available cash
shall be distributed, at such times and in such amounts as the Board determines
in its discretion, in the following order and priority;

               (i)  first, PRO RATA to the Senior Preferred Unitholders to the
     extent of the Senior Preferred Redemption Value;

               (ii) second, PRO RATA to the Junior Preferred Unitholders to the
     extent of the Junior Preferred Redemption Value;

<PAGE>

               (iii)     third, PRO RATA to the Senior Common Unitholders to the
     extent of the Senior Common Redemption Value; and

               (iv) fourth, PRO RATA to the holders of Junior Common Units.

          (b)  Notwithstanding the foregoing, the Company will not, without the
consent of CSX, make payments or distributions on, redeem or purchase the Senior
Preferred Units under Section 5.2(a)(i) to the extent that, immediately
following such distributions, the aggregate Senior Preferred Redemption Value
would be less than $100 million; PROVIDED, that (i) such consent will not be
required (A) for distributions made on the Senior Preferred Units in connection
with, or after, an Initial Public Offering, a Sale of the Company that results
in taxation of the holders of Senior Preferred Units for Federal income tax
purposes, or any transaction or transactions causing the Company not to be
treated as a partnership for federal income tax purposes or (B) after the CSX
Members cease to hold any Senior Preferred Units, and (ii) if CSX does not so
consent, (A) the Company may distribute under Section 5.2(a) (applied without
regard to clause (i) thereof) any amounts as to which a required consent was not
given and which, but for this sentence, would otherwise be distributable to the
Senior Preferred Unitholders under Section 5.2(a)(i), and (B) upon the request
of the holders of a majority of the Vectura Junior Common Units, the Vectura
Members and the CSX Members will cooperate in good faith to create a mutually
satisfactory (in their respective sole discretions) mechanism comparable to a
defeasance of the Senior Preferred Units.

      5.3 TAX ADVANCES.

          (a)  GENERAL.  At least ten days before each date prescribed by the
Code for a calendar year corporation to pay quarterly installments of estimated
tax, the Company shall distribute to each Unitholder cash in proportion to and
to the extent of such Unitholder's Quarterly Estimated Tax Amount for the
applicable calendar quarter.  If, at any time after the final Quarterly
Estimated Tax Amount has been distributed pursuant to the previous sentence with
respect to any Fiscal Year, the aggregate Tax Advances to any Unitholder with
respect to such Fiscal Year are less than such Unitholder's Tax Amount for such
Fiscal Year (a "SHORTFALL AMOUNT"), the Company shall distribute cash in
proportion to and to the extent of each Unitholder's Shortfall Amount.  The
Company shall use reasonable efforts to distribute Shortfall Amounts with
respect to a Fiscal Year before the 75th day of the next succeeding Fiscal Year.
If the aggregate Tax Advances to any Unitholder with respect to a Fiscal Year
exceed such Unitholder's Tax Amount for such Fiscal Year, such excess shall be
treated as an advance against and shall be deducted from the next succeeding
distribution (whether pursuant to this Section 5.3 or otherwise) made to such
Unitholder (and, if necessary, from any succeeding distributions thereafter)
until such excess has been fully deducted from such distribution(s).  Any such
excess applied as an advance against one or more succeeding distributions
pursuant to the preceding sentence shall be treated for purposes of this
Agreement as having been distributed under those provisions of this Agreement
under which distributions would have been made but for the preceding sentence.
Rights to distributions under this Section 5.3 shall rank senior to any rights
to distributions under Sections 5.2, 5.4 (other than Section 5.4(c) which shall
rank on a parity with distributions under Section 5.3) and 5.5.

          (b)  BUILT-IN GAIN.

               (i)  BIG REGIME.  Subject to clauses (b)(ii) and (iii) below, if
CSX Unitholders recognize Built-in Gain (other than Built-in Gain recognized as
a result of a CSX Sale-Leaseback) in any Fiscal Year, the Board shall elect (in
its sole discretion) to do one of the following (collectively, the "BIG
REGIME"):

                    (A)  reduce by the amount of the resulting BIG Tax the
     unused Aggregate Amount for subsequent Fiscal Years (or, if applicable, the
     current Fiscal Year) in inverse chronological order (i.e., by applying the
     first $3,000,000 of BIG Tax to reduce to zero the Aggregate Amount for the
     period January 1 through June 30, 2007, the next $6,000,000 of BIG Tax to
     reduce to zero the Aggregate Amount for Fiscal Year 2006, etc.);

<PAGE>

                    (B)  distribute PRO RATA to the Senior Preferred
     Unitholders, on or before June 30, 2006, cash in an amount equal to the
     lesser of (x) the resulting BIG Tax and (y) the product of (I) the C
     Corporation Tax Rate and (II) the aggregate Yield on the Senior Preferred
     Units for the period July 1, 2005 through June 30, 2006; PROVIDED that if
     such BIG Tax exceeds the amount described in the preceding clause (y), the
     Company will make additional annual distributions to the Senior Preferred
     Unitholders for the immediately preceding year (or years) in inverse
     chronological order, in each case limited to an annual amount equal to the
     product of the C Corporation Tax Rate for the year of payment and the
     aggregate Yield on the Senior Preferred Units for the applicable 12-month
     period, until such excess has been applied; PROVIDED FURTHER, that such
     election shall not be available to the extent that the BIG Tax exceeds the
     product of the C Corporation Tax Rate and the aggregate Yield payable (with
     respect to any period) on the Senior Preferred Units from the date of the
     election through and including June 30, 2006;

                    (C)  distribute to each CSX Unitholder, pursuant to Section
     5.3(a), this clause (b)(i)(C), and clause (ii)(B) of the definition of "Tax
     Amount" (without duplication), a Tax Advance equal to 50% of the resulting
     BIG Tax to such Unitholder (the "CSX 50% BIG TAX AMOUNT"); or

                    (D)  elect any combination of the foregoing.

               (ii) MONETARY DEFAULT.  If (A) Built-in Gain is recognized during
any Fiscal Year when the Company is in monetary default on any Senior Debt
either currently or on a PRO FORMA GAAP basis (absent the asset sale generating
the Built-in Gain) with respect to a monetary payment due within 120 days
following the transaction giving rise to the Built-in Gain, and (B) no
distributions (other than Permitted Payments) are made in such Fiscal Year with
respect to any Units other than CSX Units, then (x) the BIG Regime shall not
apply with respect to such Built-in Gain unless and until the Company is no
longer in monetary default, and (y) if and when the Company is no longer in
monetary default, the BIG Regime shall then apply and, to the extent at such
time an election under neither clause (i)(A) nor (i)(B) above may be made with
respect to the BIG Tax on such Built-in Gain, any remaining BIG Tax shall be
paid in part or in full pursuant to clause (C) above when and to the extent
amounts may be distributed pursuant to the terms of the Senior Debt then in
effect, PROVIDED FURTHER that any such payment shall not be treated as a Tax
Advance until the time it is paid.

               (iii)     EXEMPT TRANSACTIONS.  Except to the extent provided in
this clause (iii), the preceding clause (i) shall not apply to any Built-in Gain
incurred as a result of any Exempt Transaction. In the case of a transaction
described in clause (c) of the definition of Exempt Transaction in which the
consideration received in respect of such transaction by the Company is cash,
marketable securities, a note or the transaction is the distribution of any
asset in kind, the BIG Regime shall apply only with respect to that portion of
the BIG Tax triggered by such transaction equal to such BIG Tax multiplied by a
fraction, (A) the numerator of which is the sum (without duplication) of (i) the
amount of cash received, (ii) the value of the marketable securities received,
(iii) in the case of a note (other than a marketable security), the amount of
cash payments of principal made from time to time on the note (which payments
shall not be taken into account for purposes of this clause (iii) until the time
such payments are made), and (iv) in the case of any other asset distributed in
kind, the Fair Market Value of the asset at the time of distribution, and (B)
the denominator of which is the amount of total consideration received in the
underlying disposition.  If the Company disposes of any property (other than
cash, marketable securities or a note) received in a transaction described in
clause (c) of the definition of Exempt Transaction in a transaction in which the
Company receives cash, marketable securities or a note, the later transaction
shall trigger the BIG Regime as if the cash, marketable securities or note were
received in the original transaction.

               (iv) In all events, CSX Unreimbursed Taxes shall not exceed $85
million and the Company shall make additional Tax Advances (in the year that the
gain that would otherwise cause the CSX Unreimbursed Taxes to be in excess of
$85 million is recognized) to the CSX Unitholders as necessary (but not in
duplication of amounts distributed with respect to clause (ii)(D) of the
definition of Tax Amount) to satisfy such limitation.  Notwithstanding any other
provision hereunder, in the event of any CSX Sale-Leaseback, the Company shall
make additional Tax Advances (in the year that the Built-in Gain from such CSX
Sale-Leaseback is

<PAGE>

recognized) to the CSX Unitholders (but not in duplication of amounts
distributed with respect to clause (ii)(C) of the definition of Tax Amount)
equal to the product of the C Corporation Tax Rate and the amount of any
taxable Built-in Gain allocated to the CSX Unitholders with respect to such
CSX Sale-Leaseback.

          (c)  CERTAIN DEFINITIONS.  For purposes of this Agreement, the
following terms shall have the meanings set forth below:

     "ADJUSTED TAXABLE INCOME" of a Unitholder for a Fiscal Year (or portion
thereof) with respect to Units held by such Unitholder means the federal taxable

Preferred Units, by excluding allocations of Gross Income under Section 6.2(a)
(and corresponding taxable income under Section 6.3) with respect to the Senior
Preferred Units, (ii) in the case of any CSX Unitholder, by excluding Built-in
Gain, (iii) as if all excess taxable losses and excess taxable credits
(determined, in the case of Senior Preferred Units, without regard to any
allocations of Gross Income under Section 6.2(a) (or corresponding taxable
income under Section 6.3)) allocated with respect to such Units were carried
forward (taking into account the character of any such loss carryforward as
capital or ordinary), and (iv) taking into account any special basis adjustment
with respect to such Unitholder resulting from an election by the Company under
Code Section 754; PROVIDED FURTHER, that in the case of any Vectura Units that
are Transferred to the direct or indirect shareholders of Vectura pursuant to
Article VIII for purposes of determining the Adjusted Taxable Income with
respect to such Vectura Units for periods following the Transfer, the preceding
clause (iii) shall not apply to any excess losses and excess credits allocable
with respect to such Units for periods preceding the Transfer ending on or
before December 31, 1998.

     "AGGREGATE AMOUNT" means, for any period specified in the table below (the
"CURRENT PERIOD"), (i) the amount shown in the table opposite the current
period, (ii) increased by the amount by which the Aggregate Amount for the
immediately preceding period (as adjusted under this clause (ii) and the
following clause (iii)) exceeds the aggregate amount described in clause
(ii)(A)(x) of the definition of "Tax Amount" for such immediately preceding
period for all CSX Units, and (iii) reduced as provided under Section
5.3(b)(i)(A); PROVIDED, that the Aggregate Amount shall in all events be zero
for any period beginning on or after July 1, 2007.

(y) reduced by the aggregate tax basis of the CSX Contributed Assets as of

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

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

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

               (iii)     QUALIFIED INCOME OFFSET.  In the event any Unitholder
unexpectedly receives any adjustments, allocations or distributions described in
subparagraphs (4), (5) or (6) of Treasury Regulations Section
1.704-1(b)(2)(ii)(D), such Unitholder shall be allocated items of Company income
or gain in an amount and manner sufficient to eliminate such Unitholder's
Adjusted Capital Account Deficit as quickly as possible to the extent required
by the Treasury Regulations; PROVIDED, that an allocation pursuant to this
Section 6.2(d)(iii) shall be made only if and to the extent that such Unitholder
would have an Adjusted Capital Account Deficit after tentatively making all
other allocations provided in this Article VI as if this Section 6.2(d)(iii)
were not in this Agreement.

               (iv) NONRECOURSE DEDUCTIONS.  Nonrecourse Deductions for any
Fiscal Year shall be specially allocated among the Unitholders in proportion to
the allocations for such Fiscal Year of Net Profit under Section 6.2(b) or Net
Loss under Section 6.2(c), as applicable.  Any Member Nonrecourse Deduction for
any Fiscal Year shall be specially allocated to the Unitholder who bears the
economic risk of loss with respect to the Member

<PAGE>

Nonrecourse Debt to which such Member Nonrecourse Deductions are attributable
in accordance with Treasury Regulations Section 1.704-2(i)(1).

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

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

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

      6.3 ALLOCATIONS FOR TAX PURPOSES.

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

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

          (c)  Subject to the preceding paragraphs (a) and (b), for United
States Federal, state and local income tax purposes, the income, gains, losses

      7.1 THE BOARD; DELEGATION OF AUTHORITY AND DUTIES.

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

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

          (c)  COMMITTEES.  The Board may, from time to time, designate one or
more committees, and hereby establishes a compensation committee (the
"COMPENSATION COMMITTEE").  Each committee established by the Board shall
consist of one CSX Representative, two Vectura Party Representatives, and the
Company Representative (each as defined in Section 7.2).  Any such committee
shall have such powers and authority to make recommendations as provided in the
enabling resolution of the Company with respect thereto; PROVIDED, that (i) all
decisions of any such committee shall be merely recommendations to the Board
with respect to the taking of actions, the taking of which shall require the
approval of the Board, and (ii) if the Board rejects any such recommendation,
such matter shall be returned to such committee for its consideration (other
than with respect to the Compensation Committee's recommendations regarding the
compensation of the Company's then duly elected chief executive officer).  At
every meeting of any such committee, the presence of all members thereof shall

<PAGE>

constitute a quorum and the affirmative vote of a majority of all members shall
be necessary for the adoption of any resolution.  The Board may dissolve any
committee at any time, unless otherwise provided in this Agreement.  The
Compensation Committee shall have, among other things, the authority to select
any Officer to the extent any such position is vacant, and shall be responsible
for making recommendations with respect to the compensation of all Officers,
which recommendation shall be presented to the Board for its approval; PROVIDED,
that the Company Representative shall be recused from all proceedings of the
Compensation Committee relating to the compensation of the Company
Representative in its capacity as an Officer.

June 30, 1998 (it being understood and agreed that any Senior Preferred Units
subject to an implemented and funded mechanism comparable to a defeasance
established pursuant to Section 5.2(b) shall not be deemed to be held for
purposes of this clause (ii)). Notwithstanding anything to the contrary
contained herein, the rights accorded to CSX or any direct or indirect
Affiliate of CSX which becomes a Unitholder pursuant to clause (iv) above of
this Section 7.12(b) shall immediately terminate once CSX or such Affiliate
of CSX ceases to hold any Senior Preferred Units (or Reclassified Securities
with respect thereto) or Exchange Notes.

          (c)  SENIOR PREFERRED UNITS.  Notwithstanding anything to the contrary
contained herein, so long as any Senior Preferred Units are outstanding (it
being understood and agreed that any Senior Preferred Units subject to an
implemented and funded mechanism comparable to a defeasance pursuant to Section
5.2(b) shall not be deemed to be held for purposes of this Section 7.12(c)), the
Company and its Subsidiaries shall not take, authorize, facilitate or permit any
of the following actions without the prior Majority Approval of the Senior
Preferred Units:

               (i)  directly or indirectly declaring or making any distributions
with respect to, paying any dividends on, or redeeming or reacquiring or
purchasing or making any other payment with respect to, any Junior Security;
PROVIDED, that such restrictions shall not apply to (i) redemptions by the
Company of Units held by Management Unitholders upon the termination of their
employment with the Company or its Subsidiaries, or (ii) distributions pursuant
to Section 5.3 or permitted under Section 5.2(b);

               (ii) authorizing, creating, issuing, or entering into any
agreement providing for the sale or issuance (contingent or otherwise) of any
Units, Membership Interests or other economic interests senior, or PARI PASSU,
in priority in any respect to the Senior Preferred Units; or

               (iii)  the approval of or entering into, directly or
indirectly, any (A) transaction or group of related transactions, (B) amendment,
supplement, waiver or modification of any agreement, or (C) commitment or
arrangement, in each case with any Person in which any of the Members,
Representatives or their Affiliates, any officer or member of the Board of the
Company or any Subsidiary, or any member of the Family Group of any such Persons
owns a beneficial interest, other than such transactions, agreements,
commitments, or arrangements expressly contemplated by the Recapitalization
Agreement, the Registration Rights Agreement or this Agreement.


      7.13 AFFIRMATIVE COVENANTS.

          (a)  The Company shall take the following actions (and all actions
reasonably required to effect the same requested or approved by Majority
Approval of the Junior Common Units) upon the Majority Approval of the Vectura
Junior Common Units: (i) an Initial Public Offering (PROVIDED, that in
connection with an Initial Public Offering the Company shall abide by the
registration procedures set forth in Section 5 of the Registration Rights
Agreement); (ii) a Sale of the Company; or (iii) selection of the Accountants.

          (b)  The Company shall deliver to (i) the CSX Members and (ii) the
Vectura Members the financial statements of ACL and other notices and reports
described in, and simultaneously with the deliveries made pursuant to, Sections
5.04(a) and (b) of the Credit Agreement, as in effect on June 30, 1998, or the
correlative provisions of any successor or replacement financing or refinancing,
and similar financial statements for the Company.

      7.14 CERTAIN TAX MATTERS.

          (a)  DISPOSITIONS OF CSX CONTRIBUTED ASSETS.

               (i)  The Board shall consult with CSX prior to any proposed
taxable disposition (either in a single disposition or series of related
dispositions) of any CSX Contributed Assets for consideration in excess of
$3,000,000.

<PAGE>

               (ii) The Company shall elect out of installment sale treatment
(to the extent installment sale treatment would otherwise apply) for federal
income tax purposes with respect to sales of CSX Contributed Assets unless CSX
otherwise consents in writing.

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

          (c)  SECTION 754 ELECTION.  The Company shall make an election under
Section 754 of the Code in connection with any Transfer of Units permitted under
Section 8.2(c) and, if requested by the Transferring party, in connection with
any other permitted Transfer of Units.

          (d)  CERTAIN ARRANGEMENTS.  Without the prior approval of the holders
of a majority of the Units then held by the CSX Members, the Company and its
Subsidiaries shall not enter into any loan or other agreement or arrangement
that would restrict the Company's ability to make any distributions or payments
that are required to be made under this Agreement in a manner that would be more
restrictive than any such agreement or arrangement of the Company and its
Subsidiaries existing and in effect as of June 30, 1998 in the Credit Agreement
and the Senior Unsecured Debt Documents.

                                ARTICLE VIII
                            TRANSFERS OF UNITS

      8.1 GENERAL.

          (a)  RESTRICTIONS ON TRANSFER.  No Unitholder shall Transfer any Units
other than in accordance with the terms and conditions of this Article VIII and
the other provisions of this Agreement.  Notwithstanding anything to the
contrary contained herein, no Unitholder shall Transfer any Units or any
Derivatives (or create any Derivatives) if such Transfer or creation would cause
(i) the Company to be taxed as a C Corporation, (ii) a termination of the
Company for purposes of Section 708 of the Code (a "708 TERMINATION"), unless
the Transferring Unitholder indemnifies and reimburses the Other Unitholders for
any taxes (including interest and penalties) incurred by the Other Unitholders
that would not have been incurred but for such 708 Termination, or (iii) the
Company to be treated as a publicly-traded partnership for purposes of Section
7704 of the Code, unless, in the case of each of clauses (i), (ii), and (iii),
such Transfer or creation (A) is pursuant to an Approved Sale or Initial Public
Offering, or (B) receives the approval of the holders of a majority of the Units
then held by the CSX Members and Majority Approval of the Vectura Junior Common
Units.

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

          (c)  TRANSFER MECHANICS. In connection with any proposed Transfer of
Units, the holder of the Units proposed to be Transferred shall deliver to the
Company at least twenty (20) days (and no more than sixty (60) days) prior to
any such Transfer an opinion of counsel reasonably acceptable to the Company to
the effect that such proposed Transfer may be effected in compliance with the
Securities Act; PROVIDED, that any such proposed Transfer permitted under
Section 8.2(c) shall not require an opinion of counsel, but must otherwise be
consummated in compliance with the Securities Act. In addition, if the holder of
the Units proposed to be Transferred delivers to the Company an opinion of
counsel reasonably acceptable to the Company to the effect that no subsequent
Transfer of such Units shall require registration under the Securities Act, the
Company shall promptly upon consummation of such Transfer deliver to such holder
new certificates for such Units that do not bear the legend set forth in Section
8.4. If the Company is not required to deliver new certificates for such Units
(if certificates were previously issued for such Units) not bearing such legend,
the holder thereof shall not consummate a Transfer of the same until the
prospective Transferee has confirmed to the Company in writing its agreement to
be bound by the conditions contained herein, as provided in Section 8.1(g). In
connection with any

<PAGE>

Transfer (other than a pledge or grant of a security interest in the Senior
Preferred Units), and as a condition to the consummation thereof, the
Transferor shall obtain and deliver to the Company and each other Member a
joinder executed by the Transferee substantially in the form attached hereto
as EXHIBIT A.

          (d)  INFORMATION REQUESTS.  Upon the request of a Unitholder, the
Company shall promptly supply to such Person or its prospective Transferees all
information regarding the Company required to be delivered in connection with a
Transfer pursuant to Rule 144A under the Securities Act (or any similar rule or
rules then in effect).

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

          (f)  REMOVAL OF LEGEND.  Upon the request of any Unitholder, the
Company shall remove the legend set forth in Section 8.4 below from the
certificates for such Unitholder's Units; PROVIDED, that such Units are eligible
for sale pursuant to Rule 144(k) under the Securities Act (or any similar rule
or rules then in effect) and such Unitholder delivers to the Company an opinion
of counsel reasonably acceptable to the Company to the effect that such Units
are so eligible.

          (g)  SURVIVAL OF RESTRICTIONS.  Until the earlier of the Transfer of
Units in an Approved Sale or Public Sale, all Transferees of Units under this
Article VIII who are not parties to this Agreement (other than any pledgee or
grantee of a security interest in the Senior Preferred Units which has not
acquired such Senior Preferred Units pursuant to such pledge or grant) shall
have agreed in writing to be bound by the provisions of this Agreement by
executing a joinder substantially in the form attached hereto as EXHIBIT A and
each such Transferee shall not be deemed to be a Unitholder until such
Transferee has been admitted as a Member pursuant to the provisions of Section
3.2(b).


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

          (a)  TAG-ALONG RIGHTS.

               (i)  Subject to Section 8.2(b) and other than in connection with
     an Exempt Transfer (provided that it is hereby acknowledged and agreed that
     the CSX Members shall have the rights set forth in this Section 8.2(a) in
     connection with a Permitted Transfer by a Vectura Member pursuant to
     Section 8.2(c)(i)(E) hereof), in the event that (x) any Unitholder (other
     than an Investor Unitholder or a Management Unitholder) proposes to
     Transfer Junior Common Units or (y) a Vectura Member proposes to Transfer
     Junior Preferred Units, or (z) in any control transaction however
     structured, the Transferring Unitholder shall deliver a Transfer Notice to
     the Company and the Other Unitholders at least 30 days prior to any such
     Transfer.  The Other Unitholders holding the applicable class of Units to
     be so Transferred may elect to participate in the contemplated Transfer by
     delivering written notice to the Transferring Unitholder within 15 days
     after delivery by the Transferring Unitholder of such Transfer Notice.  If
     any Other Unitholders have elected to participate in such Transfer (such
     other Unitholders so electing, the "ELECTING UNITHOLDERS"), the
     Transferring Unitholder and such Electing Unitholders shall be entitled to
     Transfer in the contemplated Transfer, on the same contract terms, the
     number of Junior Common Units at the price determined under (ii) below and
     the number of Junior Preferred Units at the price determined under (iii)
     below; PROVIDED, that if the applicable Transfer Notice includes a Transfer
     of both Junior Common Units and Junior Preferred Units, and any Other
     Unitholder elects to participate in such Transfer, such Electing Unitholder
     must sell the number of Junior Preferred Units calculated in accordance
     with paragraph (i) below.  The restrictions on Transfer contained in this
     Section 8.2(a) shall

<PAGE>

     apply MUTATIS MUTANDIS to transfers (other than Exempt Transfers) of
     the equity securities of Vectura or any other direct or indirect
     holding company of Vectura (but not including 399 Venture or its
     direct or indirect parents and wholly-owned Subsidiaries of such parents
     (but not 399 Venture or its Subsidiaries)) holding Units by the holders of
     such equity securities.  This Section 8.2(a) shall survive any Initial
     Public Offering and terminate upon the consummation of an Approved Sale.

               (ii) In furtherance of Section 5.6, it is the intent of the
     parties that, in a transaction in which tag-along rights apply, the
     aggregate sale proceeds shall be divided proportionately with respect to
     all Electing Unitholders and the Transferring Unitholder based on each
     Electing Unitholder's and the Transferring Unitholder's respective shares
     of the liquidation proceeds that all such Electing Unitholders and the
     Transferring Unitholder would receive, respectively, in the event of a
     hypothetical liquidation of the Company at the enterprise value implied by
     the proposed sales price; and appropriate adjustments will be made to take
     account of whether Junior Preferred Units or Junior Common Units are
     subject to such tag-along.

          (b)  FIRST OFFER RIGHTS.  Other than an Exempt Transfer or a Transfer
made pursuant to Section 8.2(a), prior to any Transfer of Units by any
Unitholder, the Unitholder proposing to make such Transfer (the "OFFERING
UNITHOLDER"), shall deliver a written notice to the Company and to the Other
Unitholders holding Units of the same class proposed to be Transferred by the
Offering Unitholder (such Other Unitholders, the "UNITHOLDER OFFEREES"), such
written notice to specify in reasonable detail the number and class of Units to
be so Transferred, the proposed purchase price therefor and the other terms and
conditions of such proposed Transfer (a "FIRST OFFER NOTICE").  Subject to
Section 7.12(c)(i) hereof, the Company may elect to purchase all (but not less
than all) of the Units to be Transferred, upon the terms and conditions as those
set forth in the First Offer Notice and other reasonable and customary terms and
conditions, by delivering a written notice of such election to the Offering
Unitholder within 15 days after the First Offer Notice has been delivered to the
Company.  If the Company has not elected to purchase all of the Units to be
Transferred, the Unitholder Offerees may elect to purchase all (but not less
than all) of the Units to be Transferred, on a PRO RATA basis (based on the
Ownership Ratio of each Unitholder Offeree calculated solely with respect to the
class of Units contemplated to be Transferred) upon the same terms and
conditions as those set forth in the First Offer Notice, by giving written
notice of such election to the Offering Unitholder within 15 days after the
First Offer Notice has been delivered to the Company; PROVIDED, that if any
Unitholder Offeree elects not to purchase its PRO RATA share the Units to be
Transferred, the remaining Unitholder Offerees that have so elected may purchase
their PRO RATA share of such unpurchased Units (based on the Ownership Ratio of
each remaining Unitholder Offeree calculated solely with respect to the class of
Units contemplated to be Transferred).  If neither the Company nor the
Unitholder Offerees elect to purchase all of the Units specified in the First
Offer Notice, then the Offering Unitholder may Transfer to any Person the Units
contemplated to be Transferred at a price and on terms and conditions in the
aggregate no more favorable to the Transferee than those specified in the First
Offer Notice during the 150-day period immediately following the date on which
the First Offer Notice has been delivered to the Company and the Unitholder
Offerees.  In connection with any such Transfer, the Company shall make any
filings with Governmental Authorities necessary to consummate such Transfer.
Any Units not Transferred within such 150-day period will be subject to the
provisions of this Section 8.2(b) upon subsequent Transfer.  This Section 8.2(b)
shall terminate upon the consummation of an Initial Public Offering.

          (c)  PERMITTED TRANSFERS.

               (i)  Subject to Section 8.1, the restrictions on Transfer
     contained in Sections 8.2(a) and (b) shall not apply with respect to any
     Transfer (A) in the case of a Member which is a natural Person, of Units
     pursuant to applicable laws of descent and distribution or to any member of
     such Member's Family Group, (B) in the case of a CSX Member, (x) of Senior
     Preferred Units or Derivatives thereof or (y) of any Units among its
     Affiliates at any time after December 31, 1998, (C)(x) in the case of a
     Vectura Party, among its Affiliates, (y) in the case of each of Vectura and
     NMI, its stockholders as of June 30, 1998, so long as such Transfer occurs
     prior to June 30, 2000, (z) in the case of the majority stockholder of
     Vectura (on a fully diluted, as if converted basis), (1) its co-investment
     partnerships, and (2) in connection with a co-investment, its employees,
     directors, and internal, full-time consultants and any trust or

<PAGE>

     partnership of which its employees, directors, and internal, full-time
     consultants are the sole beneficiaries in connection with a
     co-investment (any such trust or partnership, a "CO-INVESTMENT
     VEHICLE"), (D) in the case of a Co-Investment Vehicle, of Units in-kind
     to the partners and beneficiaries of such Co-Investment Vehicle as a
     distribution in-kind, and (E) in the case of a Vectura Member, to any
     Person in order to resolve a Regulatory Problem if, (x) such Vectura
     Member, after taking commercially reasonable actions with the
     cooperation of the Company, is unable to restructure its ownership of
     such Units in a manner that avoids a Regulatory Problem and in a manner
     which is not adverse to such Vectura Member, and (y) giving notice to
     the Company and the CSX Members, such Vectura Member has determined that
     such Regulatory Problem may not be avoided.

               (ii) TRANSFERS TO MANAGEMENT UNITHOLDERS.  Subject to Section
     8.1, it is hereby acknowledged and agreed that the Company may issue and
     permit the Transfer of new Units to management (in the proportions and
     using the methodology and other terms and conditions set forth on SCHEDULE
     C attached hereto).  In connection with any such issuance of Units, and as
     a condition to the consummation thereof, the Company shall obtain and
     deliver to each Member a joinder executed by the recipient of such Units
     substantially in the form attached hereto as EXHIBIT A.

               (iii)  TRANSFERS AMONG INVESTOR UNITHOLDERS.  Subject to
     Section 8.1, each Independent Representative shall Transfer to any
     subsequent replacement Independent Representative appointed in accordance
     with Section 7.2(f) up to the full amount of the Units held by such
     Independent Representative, at a per-Unit price equal to the Fair Market
     Value (as of the date of Transfer) of such Units payable to the
     Transferring Person.


      8.3 APPROVED SALE.

          (a)  In the event of any Approved Sale, each Unitholder will (i)
consent to the Approved Sale and (ii) waive any dissenter's rights and other
similar rights available to such Unitholder.  If the Approved Sale is structured
as a sale of Units that include Junior Common Units, each Unitholder will agree
to sell all of its Units on the terms and conditions of the Approved Sale;
PROVIDED that, if the Approved Sale consists of a sale of Units, the portion of
the aggregate selling price (net of expenses of the Approved Sale) (the "SELLING
PRICE") to be delivered to each Unitholder that is selling Units in the Approved
Sale shall be equal to the amount such Unitholder would receive in respect of
their Units sold in the Approved Sale if (i) in the case of an Approved Sale of
all outstanding Units, (A) all of the Company's assets were sold for an amount
(net of all Company liabilities and expenses of the Approved Sale not described
in Section 8.3(c)) equal to the Selling Price and (B) such Selling Price were
distributed to the Unitholders in liquidation of the Company pursuant to Section
9.2(b)(iii), and (ii) in the case of an Approved Sale of less than all
outstanding Units, (A) all of the Company's assets were sold for an amount (net
of all Company liabilities and expenses of the Approved Sale not described in
Section 8.3(c)) equal to the Fair Market Value of such assets (determined
consistent with the pricing for the Approved Sale and net of all Company
liabilities and expenses of the Approved Sale not described in Section 8.3(c))
and (B) such amount were distributed to the Unitholders in liquidation of the
Company pursuant to Section 9.2(b)(iii).  Each Unitholder will take all
necessary and desirable actions as reasonably requested in connection with the
consummation of any Approved Sale, but shall not be required to execute any
purchase agreement, undertake any obligation except as provided herein or grant
indemnification other than identical indemnification rights (whether directly to
the buyer of the Units or pursuant to the provisions of a contribution
agreement) PRO RATA based on the number of Junior Common Units to be sold by
such Unitholders pursuant to the Approved Sale capped at an amount not greater
than the proceeds thereof.

          (b)  If the Company or any Unitholder or group of Unitholders enter
into any negotiation or transaction for which Rule 506 (or any similar rule then
in effect) under the Securities Act may be available with respect to such
negotiation or transaction (including a merger, consolidation, or other
reorganization), the Other Unitholders will, at the request of the Company,
appoint a purchaser representative (as such term is defined in Rule 501)
reasonably acceptable to the Company.

<PAGE>

          (c)  Costs incurred by any Unitholder on its own behalf will not be
considered costs of the transaction hereunder.


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

     "THE SECURITIES REPRESENTED BY THIS CERTIFICATE WERE ORIGINALLY ISSUED
     ON JUNE 30, 1998 AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
     OF 1933, AS AMENDED (THE "ACT"), AND THE ISSUER (THE "COMPANY") HAS
     NOT BEEN REGISTERED UNDER THE U.S. INVESTMENT COMPANY ACT OF 1940, AS
     AMENDED (THE "INVESTMENT COMPANY ACT").  THE SECURITIES REPRESENTED BY
     THIS CERTIFICATE MAY NOT BE SOLD OR TRANSFERRED (X) IN THE ABSENCE OF
     AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT OR IN THE ABSENCE OF
     AN EXEMPTION FROM REGISTRATION THEREUNDER, OR (Y) IF SUCH SALE OR
     TRANSFER CANNOT BE EFFECTED WITHOUT THE LOSS BY THE COMPANY OF ANY
     APPLICABLE INVESTMENT COMPANY ACT EXEMPTION.  THE SECURITIES
     REPRESENTED BY THIS CERTIFICATE ARE ALSO SUBJECT TO ADDITIONAL
     RESTRICTIONS ON TRANSFER SPECIFIED IN THE AMENDED AND RESTATED LIMITED
     LIABILITY COMPANY AGREEMENT, DATED AS OF JUNE 30, 1998, AS AMENDED AND
     MODIFIED FROM TIME TO TIME.  THE COMPANY RESERVES THE RIGHT TO REFUSE
     THE TRANSFER OF SUCH SECURITIES UNTIL SUCH CONDITIONS HAVE BEEN
     FULFILLED WITH RESPECT TO SUCH TRANSFER.  A COPY OF SUCH CONDITIONS
     SHALL BE FURNISHED BY THE COMPANY TO THE HOLDER HEREOF UPON WRITTEN
     REQUEST AND WITHOUT CHARGE."

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

      8.5 PRE-EMPTIVE RIGHTS.  The Company shall not engage in a Preemptive
Offering (other than Exempt Preemptive Offerings) unless the Company shall first
offer in writing to sell to each Junior Common Holder, on the same terms and
conditions and at the same equivalent price, a number of Preemptive Securities
equal to the Proportionate Amount; PROVIDED, that in the case a Junior Common
Holder elects not to exercise its rights pursuant to this Section 8.5, whether
in full or in part, each other Junior Common Holder shall have the right to
subscribe for such non-electing Junior Common Holder's Proportionate Amount.
Such offer of the Company shall remain outstanding for at least 30 days from the
date of such written notice and shall be exercised by a Junior Common Holder by
serving written notice to the Company within such 30 day period.  The foregoing
preemptive rights shall apply MUTATIS MUTANDIS to Preemptive Offerings made by
any Subsidiary of the Company.  This Section 8.5 shall terminate upon the
consummation of a Qualified Public Offering.

      8.6 INITIAL PUBLIC OFFERING.  Immediately prior to the consummation of an
Initial Public Offering, the Members and Board will take all necessary and
desirable actions in consummation of any such Initial Public Offering, and vote
for a recapitalization and/or exchange of the Units into securities (the
"RECLASSIFIED SECURITIES") the Board finds acceptable; PROVIDED, that (i) the
Reclassified Securities provide each Unitholder with the same relative economic
interest, governance, priority and other rights and privileges as such
Unitholder had prior to such recapitalization and/or exchange and are consistent
with the rights and preferences attendant to such Units as set forth in the
Agreement or Applicable Law as in effect immediately prior to such Initial
Public Offering and (ii) except as otherwise provided herein, the provisions of
this Agreement apply to the Reclassified Securities and the issuer thereof as
such provisions apply to the Units and the Company, MUTATIS MUTANDIS.

<PAGE>

      8.7 TRANSFER BY VECTURA MEMBERS.  Notwithstanding any other provision of
this Agreement to the contrary but subject to Section 8.1(a) and the penultimate
sentence of Section 8.2(a), in any transaction that would require or permit any
Vectura Member to Transfer or exchange (including, without limitation, in
connection with an Initial Public Offering or any Transfer pursuant to Section
8.2 or 8.3) all or a portion of the Vectura Units, the Vectura Members may elect
to Transfer, in lieu of such Vectura Units, stock of Vectura corresponding to
the percentage of Vectura Units to be Transferred.

      8.8 PLEDGES.  A Member shall not pledge any Membership Interest except in
accordance with the provisions in this Agreement applicable to Transfers,
including Transfers permitted under the terms and conditions of Section 8.2(c).
Except to the extent provided in Section 3.8 in connection with the foreclosure
of a pledge or of a security interest, the pledgee or grantee of a security
interest in any Units shall not be a Member or have any economic, voting or
other rights under this Agreement.  Any foreclosure of a pledge or of a security
interest shall be subject to the terms and conditions of Section 8.1.

                                 ARTICLE IX
                       DISSOLUTION AND LIQUIDATION

      9.1 DURATION.  The Company shall terminate and dissolve (and shall only
terminate and dissolve) upon (i) the sale or other disposition by the Company of
all or substantially all of the assets, properties or businesses the Company
then owns, (ii) the dissolution of the Company by action of the Board, (iii) at
any time there are no Members of the Company, unless the Company is continued
pursuant to the Act, or (iv) upon entry of a judicial decree pursuant to the Act
(each of the foregoing events, a "DISSOLUTION EVENT").


      9.2 LIQUIDATION OF COMPANY INTERESTS.

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

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

               (i)  First, to creditors, including Members and Representatives
     that are creditors, to the extent otherwise permitted by Applicable Law, in
     satisfaction of the Company's debts and obligations, including sales
     commissions and other expenses incident to any sale of the assets of the
     Company

<PAGE>

     (including a Sale of the Company) (whether by payment or the making
     of reasonable provisions for payment thereof, including the setting up of
     any reserves that the Liquidator shall determine are reasonably necessary
     or appropriate for any liabilities or obligations of the Company).

               (ii) Second, to the Unitholders, in accordance with the
     provisions of Section 5.2(a); PROVIDED, that in the event that
     distributions pursuant to this subparagraph (ii) would not otherwise be
     identical to distributions in accordance with the positive balances in the
     Unitholders' Capital Accounts, then in accordance with such positive
     balances.

The reserves established pursuant to subparagraph (i) of this Section 9.2(b)
shall be paid over by the Liquidator to a bank or other financial institution,
to be held in escrow for the purpose of paying any such liabilities or
obligations and, at the expiration of such period as the Liquidator deems
advisable, such reserves shall be distributed to the Unitholders in the
priorities set forth in this Section 9.2(b).  The allocations and distributions
provided for in this Agreement are intended to result in the Capital Account of
each Unitholder immediately prior to the distribution of the Company's assets
pursuant to this Section 9.2(b) being equal to the amount that would be
distributable to such Unitholder pursuant to this Section 9.2(b) without regard
to the proviso in subparagraph (ii).  The Company is authorized to make
appropriate adjustments in the allocation of items of income, gain, loss and
deduction as necessary to cause the amount of each Unitholder's Capital Account
immediately prior to the distribution of the Company's assets pursuant to this
Section 9.2(b) to equal the amount that would be distributable to such
Unitholder pursuant to this Section 9.2(b) without regard to the proviso in
subparagraph (ii).

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

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

                                  ARTICLE X
                               BOOKS AND RECORDS

      10.1 BOOKS.  The Company shall maintain complete and accurate books of
account of the Company's affairs at the Company's principal office, which books
shall be open to inspection by any Member (or its authorized representative) to
the extent required by the Act.  CSX and the Vectura Parties acknowledge that
they have reviewed certain illustrations of the application of Articles V and VI
hereof (assuming that the only Members are CSX, Vectura and NMI).

      10.2 TAX ALLOCATIONS AND REPORTS.  Subject to the provisions of Article
VII of the Recapitalization Agreement:

          (a)  Not later than seven calendar months after the end of each Fiscal
Year (but subject to the review procedures described in Section 7.10 of the
Recapitalization Agreement), the Board shall cause the Company to furnish each
Unitholder an Internal Revenue Service Form K-1 and any similar form required
for the

<PAGE>

filing of state or local income tax returns for such Unitholder for such
Fiscal Year.  Upon the written request of any such Unitholder and at the
expense of such Unitholder, the Company will use reasonable efforts to
deliver or cause to be delivered any additional information necessary for the
preparation of any state, local and foreign income tax return which must be
filed by such Unitholder.

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

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


      10.3 TAX PROCEEDINGS.  Any tax audit or other proceeding with respect to
the Company or any of its Subsidiaries for a taxable period that includes but
does not end on June 30, 1998 and any taxable period that begins after June 30,
1998 that might have an adverse effect on CSX shall be treated as referred to in
Section 7.8 of the Recapitalization Agreement; PROVIDED, HOWEVER, that the right
of CSX to consent to a proposed settlement, compromise or abandonment of such an
audit or proceeding pursuant to Section 7.8(b)(v) of the Recapitalization
Agreement shall apply to matters respecting the allocation of debt pursuant to
Section 6.5 of this Agreement and matters respecting any transactions that could
result in the realization of Built-in Gain of at least $1,500,000 (but such
right to consent shall otherwise not apply to such an audit or proceeding); and
PROVIDED FURTHER, HOWEVER, that, in the event that CSX reasonably withholds
consent pursuant to Section 7.8(b)(v) of the Recapitalization Agreement, then
CSX shall have the right to assume control of the defense of such audit or
proceeding (at CSX's expense) and CSX shall indemnify the Company and its
Members (other than CSX) for any liability of the Company and its Members (other
than CSX) in excess of the liability that the Company and its Members (other
than CSX) would have had under the proposed settlement, compromise or
abandonment as to which CSX reasonably withheld consent.

                                  ARTICLE XI
                       EXCULPATION AND INDEMNIFICATION

      11.1 EXCULPATION AND INDEMNIFICATION.

          (a)  No Member, Representative, Officer or any direct or indirect
officer, director, stockholder or partner of a Member (each, an "INDEMNITEE"),
shall be liable, responsible or accountable in damages or otherwise to the
Company, any Member, or to any Unitholder, for any act or failure to act by such
Indemnitee in connection with the conduct of the business of the Company, or by
any other such Indemnitee in performing or participating in the performance of
the obligations of the Company, so long as such Indemnitee acted in the good
faith belief that such action or failure to act was in the best interests, or
not opposed to the best interests, of the Company and/or its Subsidiaries and
such action or failure to act was not in violation of this Agreement and did not
involve intentional misconduct or a knowing violation of Applicable Law. No
Person who is a Member, Representative, an Officer, or any combination of the
foregoing, shall be personally liable under any judgment of a

<PAGE>

court, or in any other manner, for any debt, obligation, or liability of the
Company, whether that liability or obligation arises in contract, tort, or
otherwise, solely by reason of being a Member, Representative, an Officer, or
any combination of the foregoing. Nothing contained in this Agreement shall
affect the rights of the Company against any Member pursuant to the terms and
conditions of the Recapitalization Agreement.

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

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

      11.2 INSURANCE.  The Company shall have the power to purchase and maintain
insurance on behalf of any Indemnitee or any Person who is or was an agent of
the Company against any liability asserted against such Person and incurred by
such Person in any such capacity, or arising out of such Person's status as an
agent, whether or not the Company would have the power to indemnify such Person
against such liability under the provisions of Section 11.1 or under Applicable
Law.

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

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

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

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

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

                                MISCELLANEOUS

      12.1 CONFIDENTIALITY.  By executing this Agreement, each Member expressly
agrees, at all times during the term of the Company and thereafter and whether
or not at that time it is a Member of the Company, (unless the prior written
consent of the Company is obtained, which prior consent shall not be
unreasonably withheld) to maintain the confidentiality of, and not to disclose
to any Person other than the Company, another Member or a person designated by
the Company, any information obtained from the Company or its representatives
that is not generally available or known to the public and which has not been
previously disclosed by any Member without a confidentiality agreement relating
to the identity of any Member, the business, financial structure, financial
position or financial results, clients or affairs of the Company; PROVIDED, that
each Member may deliver or disclose confidential information to (i) its
directors, officers, employees, agents, attorneys and affiliates (to the extent
such disclosure reasonably relates to the administration of the investment
represented by its interest in the Company and such Persons agree to comply with
the terms of this Section), (ii) its financial advisors and other professional
advisors who agree to comply with the terms of this Section, (iii) any Person to
which it sells or offers to sell its interest in the Company or any part thereof
or any participation therein in accordance with the transfer restrictions
contained in this Agreement (if such Person has agreed in writing prior to its
receipt of such confidential information to be bound by the provisions of this
Section), (iv) any Governmental Authority or other regulatory or self regulatory
authority having jurisdiction over a Member or any nationally recognized rating
agency that requires access to information about a Member's investment
portfolio, or (v) any other Person to which such delivery or disclosure may be
necessary or advisable (a) to effect compliance with any law, rule, regulation
or order applicable to a Member, including the requirements of any stock
exchange, (b) in response to any subpoena or other legal process, or (c) in
connection with any litigation to which a Member is a party.

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

      12.3 GOVERNING LAW.  ALL ISSUES AND QUESTIONS CONCERNING THE APPLICATION,
CONSTRUCTION, VALIDITY, INTERPRETATION AND ENFORCEMENT OF THIS AGREEMENT SHALL
BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF

applicable law, but if any provision of this Agreement is held to be invalid,
illegal or unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability shall not affect
any other provision or any other jurisdiction, but this Agreement shall be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision had never been contained herein. The Members
shall negotiate in good faith to replace any provision so held to be invalid or
unenforceable so as to implement most effectively the transactions contemplated
by such provision in accordance with the original intent of the Members
signatory hereto.

      12.6 AMENDMENTS.  Subject to Section 7.12(b)(iii), the parties hereto may
at any time amend this Agreement through action of the Board and Majority

enforceable by specific performance, injunction or other suitable remedy, but
nothing herein contained is intended to or shall limit or affect any rights at
law or by statute or otherwise of any party aggrieved as against the other
parties for a breach or threatened breach of any provision hereof, it being the
intention by this Section to make clear the agreement of the parties that the
respective rights and obligations of the parties hereunder shall be enforceable
in equity as well as at law or otherwise.

      12.13 BINDING EFFECT.  This Agreement shall be binding upon and inure to
the benefit of all of the Members and their permitted successors, legal
representatives, and assigns.

Market Values reflected on Schedule B, the Board shall reasonably determine Fair
Market Values hereunder; PROVIDED, that in the event the holders of 10% of any

appraiser mutually reasonably satisfactory to the Company and the Requesting
Holders, whose fees and expenses shall be borne by the Company if the Board's
determination differs from the appraiser's determination by at least 15% of the
appraiser's determination and shall otherwise be borne by the Requesting
Holders.

by the Company; PROVIDED, that if any Other Unitholder elects not to purchase
its PRO RATA share of the Units to be repurchased, the remaining Other
Unitholders that have so elected may purchase their PRO RATA share of such

aggregate purchase price and the time and place of the closing of the
transaction. If the Executive has Transferred any Executive Stock to a

Unitholders (or their respective designees) shall be entitled to receive
customary representations and warranties from the Executive regarding such
sale of Units (including representations and warranties regarding good title
to such Units, free and clear of any liens or encumbrances). Any Executive
Units not purchased pursuant to the Repurchase Option shall become Vested
Units.

(or their respective designees) to repurchase the Executive Units pursuant to
this Section 4 shall terminate upon a Sale of the Company or a Qualified

         10.      MISCELLANEOUS.

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

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

                  (c) COMPLETE AGREEMENT. This Agreement, the LLC Agreement,
and the Registration Rights Agreement embody the complete agreement and
understanding among the parties and supersede and preempt any prior
understandings, agreements or representations by or among the parties,
written or oral, which may have related to the subject matter hereof in any
way.

<PAGE>

                  (d) WAIVER OF JURY TRIAL. The parties to this Agreement
each hereby waives, to the fullest extent permitted by law, any right to
trial by jury of any claim, demand, action, or cause of action (i) arising
under this Agreement or (ii) in any way connected with or related or
incidental to the dealings of the parties hereto in respect of this Agreement
or any of the transactions related hereto, in each case whether now existing
or hereafter arising, and whether in contract, tort, equity, or otherwise.
The parties to this Agreement each hereby agrees and consents that any such
claim, demand, action, or cause of action shall be decided by court trial
without a jury and that the parties to this Agreement may file an original
counterpart of a copy of this Agreement with any court as written evidence of
the consent of the parties hereto to the waiver of their right to trial by
jury.

                  (e) COUNTERPARTS. This Agreement may be executed in one or
more counterparts, each of which when executed and delivered shall be an
original, and all of which when executed shall constitute one and the same
instrument.

                  (f) SUCCESSORS AND ASSIGNS. Except as otherwise provided
herein, this Agreement shall bind and inure to the benefit of and be enforceable
by the Executive, the Company, and their respective successors and assigns
(including subsequent holders of Executive Units); PROVIDED, that the rights
and obligations of the Executive under this Agreement shall not be assignable
except in connection with a permitted transfer of Executive Units hereunder.

                  (g) GOVERNING LAW. THE LAWS OF THE STATE OF DELAWARE AND
THE ACT WILL GOVERN ALL QUESTIONS CONCERNING THE RELATIVE RIGHTS OF THE
COMPANY AND ITS UNITHOLDERS. ALL OTHER QUESTIONS CONCERNING THE CONSTRUCTION,
VALIDITY AND INTERPRETATION OF THIS AGREEMENT AND THE EXHIBITS HERETO WILL BE
GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE DOMESTIC LAWS OF THE STATE
OF NEW YORK, WITHOUT GIVING EFFECT TO ANY CHOICE OF LAW OR CONFLICT OF LAW
PROVISION OR RULE (WHETHER OF THE STATE OF NEW YORK OR ANY OTHER
JURISDICTION) THAT WOULD CAUSE THE APPLICATION OF THE LAWS OF ANY
JURISDICTION OTHER THAN THE STATE OF NEW YORK.

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

                  (i) AMENDMENT AND WAIVER. The provisions of this Agreement
(except for the provisions of Section 2 hereof) may be amended and waived
only with the prior written consent of the Company and the Executive;
provided, that the provisions of Section 2 hereof may be amended and waived
only with the prior written consent of each party hereto.

                  (j) TIMING. Time shall be of the essence in the performance
of the obligations, covenants and agreements contained in this Agreement.
