terms shall have the meanings specified in this Section 1.1:

1.1.1 Act: The Texas Revised Limited Partnership Act.

1.1.2 Additional Capital Contributions: The additional capital
contributions described in Section 3.4.

1.1.3 Adjusted Capital Account Deficit: With respect to any Partner,
the deficit balance, if any, in such Partner's Capital Account as
of the end of the relevant taxable year, after giving effect to
the following adjustments:

(a) Credit to such Capital Account any amounts which such
Partner (1) is obligated to restore to the Partnership upon
liquidation of its interest in the Partnership (or which is
so treated pursuant to Regulations Section
1.704-1(b)(2)(ii)(c)) pursuant to the terms of this
Agreement or under state law or (2) is deemed to be
obligated to restore pursuant to the penultimate sentences
of Regulations Sections 1.704-2(g)(1) and 1.704-2(i)(5) and
(3) the Partner's share (as determined under Code Section
752) of any recourse indebtedness of the Partnership to the
extent that such indebtedness could not be repaid out of the
Partnership's assets if all of the Partnership's assets were
sold at their respective Book Values as of the end of the
Fiscal Year or other period and the proceeds from the sales
were used to pay the Partnership's liabilities; and

(b) Debit to such Capital Account the items described in
Sections 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5),
and 1.704-1(b)(2)(ii)(d)(6) of the Regulations.

The foregoing definition of Adjusted Capital Account Deficit is
intended to comply with the provisions of Section
1.704-1(b)(2)(ii)(d) of the


1

<PAGE>

Regulations and shall be interpreted consistently therewith. For
purposes of clause (a)(3) above, the amounts computed pursuant to
clause (a)(1) above for each Partner shall be considered to be
proceeds from the sale of the assets of the Partnership to the
extent such amounts would be available to satisfy (directly or
indirectly) the indebtedness specified in clause (a)(3).

1.1.4 Affiliate: With respect to any Person, a Person that directly or
indirectly, through one or more intermediaries, controls, is
controlled by, or is under common control with the Person in
question. As used herein, the term "control" means the
possession, directly or indirectly, of the power to direct or
cause the direction of the management and policies of a Person,
whether through ownership of voting securities or interests, by
contract, or otherwise.

1.1.5 Agreement: This Agreement of Limited Partnership of Ingram
Enterprises, L.P. and any amendments hereto.

1.1.6 Bankruptcy: A Person shall be deemed bankrupt if:

(a) any proceeding is commenced against such Person as "debtor"
for any relief under bankruptcy or insolvency laws, or laws
relating to the relief of debtors, reorganizations,
arrangements, compositions, or extensions and such
proceeding is not dismissed within sixty (60) days after
such proceeding has commenced, or

(b) such Person commences any proceeding for relief under
bankruptcy or insolvency laws or laws relating to the relief
of debtors, reorganizations, arrangements, compositions, or
extensions.

1.1.7 Book Value: With respect to any asset, the asset's adjusted
basis for federal income tax purposes, except as follows:

(a) the initial Book Value of any asset contributed (or deemed
contributed under Regulations Section 1.708-1(b)(1)(iv)) by
a Partner to the Partnership shall be the asset's gross fair
market value at the time of the contribution;

(b) the Book Value of all Partnership assets shall be adjusted
to equal their respective gross fair market values, as
determined by the General Partner in its reasonable
judgment:

(i) if the General Partner reasonably determines an
adjustment is necessary or appropriate to reflect the
relative economic interests of the Partners in the
Partnership as of (1) the acquisition of an additional
interest in the Partnership by any new or existing
Partner in exchange for more than a de


2

<PAGE>

minimis capital contribution, or (2) the distribution
by the Partnership to a Partner of more than a de
minimis amount of Partnership property as consideration
for an interest in the Partnership; and

(ii) as of the liquidation of the Partnership within the
meaning of Regulations Section 1.704-1(b)(2)(ii)(g);

(c) the Book Value of any Partnership asset distributed to any
Partner will be the gross fair market value of the asset on
the date of distribution; and

(d) the Book Values of Partnership assets will be increased or
decreased to reflect any adjustment to the adjusted basis of
the assets under Code Sections 734(b) or 743(b), but only to
the extent that the adjustment is taken into account in
determining Capital Accounts under Regulations Section
1.704-1(b)(2)(iv)(m), provided that Book Values will not be
adjusted hereunder to the extent that the General Partner
determines that an adjustment under clause (b) is necessary
or appropriate in connection with a transaction that would
otherwise result in an adjustment under this clause (d).

After the Book Value of any asset has been adjusted under clause
(a), clause (b) or clause (d) above, Book Value will be adjusted
by the Depreciation taken into account with respect to the asset
for purposes of computing Net Profit and Net Loss.

1.1.8 Capital Account: The capital account of a Partner established
and maintained in accordance with Section 5.1.

1.1.9 Capital Contributions: With respect to any Partner, the amount

contributed to the Partnership with respect to the interest in
the Partnership held by that Partner (net of any liabilities
secured by such property that the Partnership is considered to
assume or to take subject to Code Section 752). Any reference in
this Agreement to the Capital Contribution of a Partner will
include a Capital Contribution made by any prior Partner with

the federal income tax depreciation, amortization or other cost
recovery deduction for the year or other period bears to the
beginning adjusted tax basis, provided that if the federal income
tax depreciation, amortization, or other cost recovery deduction
for the year or other period is zero, Depreciation will be
