	LIMITED LIABILITY COMPANY AGREEMENT


	This LIMITED LIABILITY COMPANY AGREEMENT (this "Agreement") 
of Radian International LLC (the "Company"), dated as of January 
1, 1996, is between Dow Environmental Inc., a Delaware 
corporation ("DEI") and Radian Corporation, a Texas corporation 
("Radian").  DEI and Radian are sometimes individually referred 
to in this Agreement as a "Member" and collectively as "Members".

	NOW, THEREFORE, the parties agree as follows:




 ARTICLE I 

	DEFINITIONS

I.1   Definitions.  Capitalized terms used in this Agreement 
which are not otherwise defined in this Agreement shall have the 
meanings given to such terms in Exhibit A.


ARTICLE II 

FORMATION

II.1   Formation of the Company.  The Members hereby form a 
limited liability company pursuant to the Act on the terms and 
for the purposes set forth in this Agreement.  The rights and 
duties of the Members and the administration and termination of 
the Company shall be as provided in the Act, except as modified 
by this Agreement.

II.2   Name.  The name of the Company shall be "Radian 
International LLC" or such other name as is designated from time 
to time by the Members and, if such other name is to contain 
"DOW", as approved by The Dow Chemical Company ("TDCC").  The 
Members Committee is hereby directed to file, or cause to be 
filed, with the Secretary of State of the State of Delaware a 
Certificate of Formation reflecting the name of the Company.

II.3   Purposes.  The purposes of the Company shall be to 
engage for profit in the Newco Services Business and to engage 
for profit in any and all other activities reasonably related to 
or incidental to the Newco Services Business, and to engage for 
profit in any other business, whether or not related or 
incidental thereto, as determined by the Members from time to 
time; provided, however, that the Company shall not engage in the 
production or manufacture of chemical products, other than the 
chemical products manufactured by Radian as of the Closing Date 
and listed on Schedule 2.3, or disclose technology received from 


TDCC to any third party if such technology is to be used by, or 
on behalf of, the third party to optimize its production or 
manufacture of chemical products that are being, or will be, 
manufactured or produced by TDCC.  Notwithstanding the foregoing, 
the Company may engage in the production or manufacture of 
analytical reference standard materials for end uses such as 
environmental, pharmaceutical and forensic drug analyses, such 
materials typically being manufactured and sold in microgram and 
gram quantities, but with potential sales up to ten (10) 
kilograms per material or product to a given purchaser in a 
twelve month period; provided, however, that potential sales in 
quantities that exceed the ten (10) kilogram limit will be 
referred to the Members Committee for approval.

II.4   Powers of the Company.  Subject to the restrictions 
set forth in this Agreement, the Company shall have the power to 
exercise all the powers and privileges granted by this Agreement 
and by law, together with any powers incidental thereto, so far 
as such powers and privileges are necessary or appropriate for 
the conduct, promotion or attainment of the purposes of the 
Company.

II.5   Member's Authority.  Except as otherwise provided in 
this Agreement, no Member shall have any authority to act for, or 
to assume any obligations or responsibilities on behalf of, any 
other Member or the Company.

II.6   Company Property.  All real and personal property, 
whether tangible or intangible (including, without limitation, 
all permits and licenses), owned by or granted to or held by the 
Company shall be deemed to be owned by or granted to or held by 
the Company as an entity, and no Member shall have any ownership 
or right to use any such property, except as may be otherwise 
agreed by the Company and the Members.

II.7   Principal Place of Business; Registered Office and 
Agent.  The principal place of business of the Company shall be 
located at Austin, Texas or at such other place or places as the 
Members Committee may from time to time determine.  The business 
of the Company may also be conducted at such additional place or 
places as the Members Committee may designate; provided, however, 
that the Company shall not maintain an office or a principal 
place of business in any jurisdiction that would jeopardize the 
limitation on liability afforded to the Members under the Act or 
this Agreement and; provided, further, that the Members Committee 
shall take, or cause to be taken, all steps necessary to preserve 
the limited liability of the Members in connection with any such 
additional places of business.

II.8   Office of and Agent for Service of Process.  The 
registered office of the Company in Delaware shall be Corporation 
Trust Center, 1209 Orange Street, Wilmington, Delaware 19801.  
The Company's agent for service of process on the Company in 
Delaware shall be The Corporation Trust Company.  The Members 
Committee may change, at any time and from time to time, the 
location of such registered office and/or such registered agent 
upon written notice of the change to the Members.


ARTICLE III 

CAPITAL CONTRIBUTIONS

III.1   Initial Contributions.  On the Closing Date (or in 
the case of Restricted Assets and liabilities associated thereto, 
after the Closing Date), certain contributions will be made to 
the Company by or on behalf of, and the Company will assume 
certain liabilities of, the Members and their Affiliates, all as 
provided in the Contribution Agreement (the "Capital 
Contribution").  The Members agree that immediately after such 
contributions and assumptions, the sum of the cash and the Gross 
Asset Value of assets other than cash contributed by each Member, 
reduced by liabilities of such Member assumed by the Company, to 
be contributed to the Capital Account of each of DEI and Radian, 
respectively, will be as follows:

		DEI                     $225,000,000
		Radian                  $150,000,000

III.2   Return of Capital Contribution.

(a) 	Except as otherwise provided in this Agreement, no 
return shall be paid by the Company to any Member on account of 
any Capital Contribution.  No Member shall have liability to any 
other Member for the return of any Capital Contribution and any 
such return shall be made only to the extent of available Company 
assets in accordance with the terms of this Agreement.

(b) 	Except as otherwise provided in this Agreement, no 
Member shall have priority over the other Member as to the return 
of its Capital Contribution or as to distributions of cash made 
by the Company.

(c) 	Except as otherwise provided in this Agreement, a 
Member shall not be entitled to withdraw any part of its capital 
or to (i) receive any distributions from the Company, (ii) demand 
or receive property other than cash in return for its Capital 
Contribution or (iii) receive any funds or property of the 
Company.

III.3   Interest.  No interest shall be paid on any capital 
contributed to the Company, notwithstanding any disproportion 
between the Capital Contribution of each of the Members.

III.4   Liability of Members.  Except as otherwise provided 
in the Act and except with respect to their several respective 
obligations under this Agreement to contribute their respective 
Capital Contributions, the Members shall not have any personal 
liability to contribute money or other property to, or in respect 
of, the Company or any of its liabilities or obligations.

III.5   Additional Contributions.

(a) 	No Company Interest or other ownership interest in the 
Company or its assets other than those of the Members shall be 
issued by the Company without the consent of each Member and, 
except as provided in Section 3.1 and this Section 3.5, no Member 
shall be obligated to make any additional contributions to the 
capital of the Company.

(b) 	Subject to Section 3.5(e), the Members Committee shall, 
if it reasonably determines that the Company needs additional 
funds, use its commercially reasonable efforts to obtain a credit 
facility (a "Credit Facility") from one or more commercial 
lenders in form and substance reasonably satisfactory to the 
Members Committee.

(c) 	If the Members Committee reasonably determines, in its 
sole discretion, that it is desirable for the Company to obtain a 
guarantee of such Credit Facility, each Member shall cause its 
respective Parent to provide such a guarantee, in form and 
substance reasonably satisfactory to the Parents and such 
commercial lenders, of the amount of such Credit Facility 
multiplied by each Member's Company Interest; provided, however, 
that if a guarantee is required subsequent to December 31, 1998, 
then, for purposes of this Section 3.5(c), each Member's Company 
Interest shall be its respective Company Interest as of 
January 1, 2000. 

(d) 	Subject to Sections 3.5(e) and (g), if, after using 
commercially reasonable efforts to obtain a Credit Facility 
pursuant to Sections 3.5(b) and (c), the Members Committee 
reasonably determines, in its sole discretion, that such Credit 
Facility cannot be obtained on commercially reasonable terms 
pursuant to Sections 3.5(b) and (c) or if the Credit Facility 
obtained by the Company is insufficient for the needs of the 
Company, then each of DEI and Radian hereby agrees to make loans 
to the Company (the "Ordinary Loans") in order to support the 
needs of the Company in form and substance reasonably satis-
factory to Radian and DEI.  The Company's authorized officer 
shall notify DEI and Radian in writing at least three (3) 
business days in advance of the time each such loan is required 
to be made to the Company.  Upon such a written request from the 
Company's authorized officer, each Member shall make a cash loan 
to the Company in an amount equal to (i) the amount of the 
Company's loan determined to be needed by the Members Committee 
multiplied by (ii) such Member's Company Interest; provided, 
however, that if an Ordinary Loan is required subsequent to 
December 31, 1998, then, for purposes of this Section 3.5(d), 
each Member's Company Interest shall be its respective Company 
Interest as of January 1, 2000.  An Ordinary Loan shall bear 
interest at the rate equal to the lower of (i) the maximum rate 
allowed by law or (ii) two (2) percentage points over the Prime 
Rate.

(e) 	Notwithstanding the foregoing, the aggregate amount 
borrowed under the Credit Facility or any Ordinary Loans shall 
not result in a Debt Ratio in excess of 0.40.

(f) 	Prior to January 1, 1999, no additional cash 
contributions may be required without the prior written consent 
of each of the Members.  If, on or after January 1, 1999, the 
Members Committee determines that the Company requires funds and 
that borrowings under a Credit Facility or an Ordinary Loan in 
response to such requirement would cause the Debt Ratio to exceed 
0.40, each of DEI and Radian hereby agrees that it shall make 
cash contributions to the Company in an amount equal to (i) the 
amount of the Company's cash requirement in excess of the amount 
that would cause the Debt Ratio to equal 0.40 as determined by 
the Members Committee multiplied by (ii) such Member's Company 
Interest; provided, however, that if an additional cash 
contribution is required on or prior to December 31, 1999, then, 
for purposes of this Section 3.5(f), each Member's Company 
Interest shall be its respective Company Interest as of 
January 1, 2000.  Once the Members Committee approves an 
additional cash contribution, the Company's officers shall have, 
subject to any terms or conditions specified by the Members 
Committee at the time it so approves such additional cash 
contribution, the reasonable discretion to determine the timing 
of such cash contribution giving due consideration to the 
Company's cash needs as determined by the Members Committee.  The 
Company's authorized officer shall notify DEI and Radian at least 
ten (10) days in advance of the time each such cash contribution 
is required to be made to the Company.

	(g)	Notwithstanding the foregoing (and regardless of 
whether the Debt Ratio is less than or equal to 0.40), no Member 
shall be required to make any cash contribution, to guarantee the 
Credit Facility or to make Ordinary Loans if to do so would cause 
such Member or its respective Affiliates to violate any Federal, 
state or local law or regulation applicable to such Member or its 
respective Affiliates or would, by operation of any such law or 
regulation, significantly restrict the Member's or its respective 
Affiliates' ability to conduct its business as such business was 
conducted prior to the Closing.  Each Member shall use, and shall 
cause its respective Affiliates to use, all reasonable efforts to 
maintain its ability to make the cash contributions, guarantees 
and loans contemplated by this Section 3.5.



III.6   Failure to Contribute.  If either DEI or Radian (in 
either such case, the "Non-Contributing Member") (x) fails 
(including a failure because of legal requirements as permitted 
by Section 3.5(g)), in whole or in part, to make any cash 
contribution, to guarantee the Credit Facility or to make 
Ordinary Loans or (y) defaults, in whole or in part, on any other 
obligation to pay money under this Agreement within five (5) 
business days of giving of notice by the other Member to the Non-
Contributing Member that such cash contribution, guarantee or 
Ordinary Loan is due or that the Non-Contributing Member has 
defaulted in any other such obligation under this Agreement, DEI 
(with respect to circumstances in which Radian is the Non-
Contributing Member) or Radian (with respect to circumstances in 
which DEI is the Non-Contributing Member), as the case may be (in 
either such case, the "Contributing Member"), shall have the 
right to:

(i)   advance directly to the Company such additional 
cash contribution or provide such guarantee or Ordinary 
Loan, or portion thereof, or such other payment of money, or 
portion thereof, as the Non-Contributing Member has failed 
to make or defaulted on (the "Non-Contributing Member's 
Share"), and such advance, together with a proportionate 
amount of the corresponding cash contribution or other 
payment, if any, made by such Contributing Member, shall be 
deemed a loan by the Contributing Member to the Company (a 
"Member Loan").  A Member Loan shall bear interest at the 
rate equal to the lower of: (A) the maximum rate allowed by 
law; or (B) four (4) percentage points over the Prime Rate. 
 A Member Loan shall be recouped and repaid from all funds 
which would have been available to make distributions which 
the Members would otherwise be entitled to receive from the 
Company but for this Section 3.6, all of which shall instead 
be paid by the Company to the Contributing Member and 
applied to the payment of the Member Loan and all interest 
thereon, until the same shall have been paid in full.  It is 
understood, however, that to the extent the principal and 
interest of a Member Loan are not repaid in full by the 
Company from all funds which would otherwise have been 
available to make distributions (including any distributions 
pursuant to Section 9.6(b)) to the Members, the Non-
Contributing Member shall be obligated to repay an amount 
equal to the Non-Contributing Member's Share of the 
outstanding balance of the principal and interest of such 
Member Loan upon commencement of the winding up of the 
Company in accordance with Section 9.2.  Any amount which 
would otherwise have been available to make distributions 
from the Company that is applied to any Member Loan shall be 
credited first to any interest then due on such Member Loan, 
and the balance of the distribution shall be credited 
against the outstanding principal balance of such Member 
Loan; or

(ii)  upon notice to the Non-Contributing Member, 
purchase all, but not less than all, of the Non-Contributing 
Member's Company Interest, (A) if on or prior to 
December 31, 1998, at the price equal to the amount set 
forth in Section 8.3 of this Agreement as if Radian had 
exercised its option to sell; provided, however, that such 
price shall be discounted at a rate of 10% per year or 
portion thereof if such purchase shall occur prior to 
December 31, 1997, and (B) thereafter, at the fair market 
value therefor.  Notwithstanding the foregoing, if the 
enforceability of such Contributing Member's right to 
purchase the Non-Contributing Member's Company Interest as 
set forth in this subsection (ii) is in any way limited by 
general equitable principles, Bankruptcy, moratorium, or 
other laws affecting creditors' rights generally then, upon 
notice to the Non-Contributing Member and the Company, the 
Contributing Member or any of its Affiliates shall have the 
right to purchase all, but not less than all of the assets 
and liabilities of the Company at the fair market value 
therefor.  In either case, if DEI and Radian cannot agree 
upon such fair market value within sixty (60) days after the 
notice to purchase the Non-Contributing Member's Interest or 
all the assets and liabilities of the Company, as the case 
may be, is delivered, either DEI or Radian may, by notice to 
the other, invoke the Appraisal Procedure.  If the Appraisal 
Procedure is required to determine the fair market value of 
the Non-Contributing Member's Interest or all the assets and 
liabilities of the Company, as the case may be, the fees and 
expenses of such Appraisal Procedure shall be paid by the 
Non-Contributing Member.  The closing of either such sale 
shall take place upon the date that is within thirty (30) 
days after such fair market value is determined in 
accordance with this Section 3.6 and all legal requirements 
relating to such sale have been satisfied; provided, 
however, that if such sale is not in compliance with any 
such legal requirements, then DEI and Radian shall equitably 
adjust the arrangements set forth in this Section 3.6(ii) in 
light of what is legally possible and in compliance with any 
such legal requirements in order to effectuate the intent of 
the parties.

	Notwithstanding the foregoing, if the Non-Contributing 
Member fails, in whole or in part, to make any cash contribution, 
to guarantee the Credit Facility or to make Ordinary Loans 
because of legal requirements as permitted by Section 3.5(g), 
then the Contributing Member shall only have the rights set forth 
in subsection (i) above; provided, however, that any Member Loan 
caused by legal requirements as permitted by Section 3.5(g) shall 
bear interest equal to the interest rate paid on an Ordinary 
Loan.  

	Except as set forth above, the exercise of the right to make 
a Member Loan or purchase the Non-Contributing Member's Company 
Interest shall be in addition to any other rights or remedies 
that the Contributing Member may have under this Agreement or at 
law or in equity arising from the Non-Contributing Member's (i) 
failure to make the required cash contribution, (ii) failure to 
provide its portion of the required guarantee, (iii) failure to 
make its required loan or (iv) default in any other obligation to 
pay money.

Account or its contributions to the capital of the Company.

IV.4   Loans from Members.  Loans by a Member to the Company 
(including, without limitation, any Ordinary Loan or Member Loan)

IV.5   Transferred Capital Accounts.  In the event that any 
Member transfers all or a portion of its Company Interest in

Interest or portion thereof.

ARTICLE V 

DISTRIBUTIONS, EXPENSES AND  
ALLOCATIONS OF PROFITS AND LOSSES

V.1   Allocations of Net Profits and Net Losses from 
Operations.

(a) 	Allocation of Net Profits.  Subject to Section 5.2 and 
Section 9.4, the Net Profits of the Company for each Fiscal Year 
will be allocated as follows:

(i)    Net Profits will first be allocated to the 
Members to offset prior allocations of Net Losses pursuant 
to Section 5.1(b)(ii) to the extent such allocations have 
not been so offset;

(ii)   next, Net Profits will be allocated to the 
Members in proportion to their Company Interests as of the 
last day of the Fiscal Year to which such Net Profits are 
attributable.

(b) Allocation of Net Losses.  Subject to Section 5.2 and 
Section 9.4, the Net Losses of the Company for each Fiscal Year 
will be allocated as follows:

(i)    First, Net Losses shall be allocated to the 
Members in proportion to their Company Interests as of the 
last day of the Fiscal Year to which such Net Losses are 
attributable;

(ii)   Except as otherwise required by the last sentence 
of this Section 5.1(b)(ii), no allocation of loss, 
deduction, and/or expenditures described in Code 
Section 705(a)(2)(B) shall be charged to the Capital 
Accounts of any Member if such allocation would cause such 
Member to have an Adjusted Deficit Capital Account.  The 
amount of the loss, deduction, and/or Code 
Section 705(a)(2)(B) expenditure which would have caused a 
Member to have an Adjusted Deficit Capital Account shall 
instead be charged to the Capital Account of any Members 
which would not have an Adjusted Deficit Capital Account as 
a result of the allocation, in proportion to their positive 
Capital Accounts (after giving effect to the adjustments 
described in the definition of Adjusted Deficit Capital 
Account), or, if no such Members exist, then to the Members 
in accordance with their Company Interest.

(c) 	Proportionate Share of Items.  All allocations of Net 
Profits and Net Losses shall be deemed to be comprised of a 
proportionate share of all items comprising such Net Profits and 
Net Losses.

V.2   Special Allocations.

(a) 	If any Member unexpectedly receives any adjustments, 
allocations, or distributions described in Treas. Regs. 
Section 1.704-1(b)(2)(ii)(d)(4), (5), or (6), which create or 
increase an Adjusted Deficit Capital Account of the Member, then 
items of Company income and gain (consisting of a pro rata 
portion of each item of Company income, including gross income, 
and gain for such year) shall be specially allocated to the 
Capital Account of the Member in an amount and manner sufficient 
to eliminate, to the extent required by the Treasury Regulations, 
the Adjusted Deficit Capital Account so created as quickly as 
possible; provided, however, that an allocation pursuant to this 
Section 5.2(a) shall be made only if and to the extent that such 
Member would have an Adjusted Deficit Capital Account after all 
other allocations provided for in this Section 5.2 have been 
tentatively made as if this Section 5.2(a) were not in this 
Agreement.  It is intended that this Section 5.2(a) be 
interpreted to comply with the alternate test for economic effect 
set forth in Treas. Regs. Section 1.704-1(b)(2)(ii)(d).

(b) 	If any Member would have a deficit Capital Account at 
the end of any Company taxable year which is in excess of the sum 
of (i) the amount that the Member is obligated to restore to the 
Company under Treas. Regs. Section 1.704-1(b)(2)(ii)(c) and (ii) 
the amount such Member is deemed to be obligated to restore 
pursuant to the penultimate sentences of Treas. Regs. 
Sections 1.704-2(g)(1) and 1.704-2(i)(5), such Member shall be 
specially allocated items of Company income (including gross 
income) and gain in the amount of the excess as quickly as 
possible; provided, however, that an allocation pursuant to this 
Section 5.2(b) shall be made only if and to the extent that such 
Member would have a deficit Capital Account in excess of such sum 
after all other allocations provided for in this Section 5.2 have 
been made as if Section 5.2(a) and this Section 5.2(b) were not 
in this Agreement.

(c) 	Except as otherwise provided in Treas. Regs. 
Section 1.704-2(f), notwithstanding any other provision of this 
Section 5.2, if there is a net decrease in Partnership Minimum 
Gain during any Fiscal Year, each Member 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 Member's share of the net decrease in Partnership Minimum 
Gain, determined in accordance with Treas. Regs. 
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 Member pursuant thereto.  The 
items to be so allocated shall be determined in accordance with 
Treas. Regs. Sections 1.704-2(f)(6) and 1.704-2(j)(2).  This 
Section 5.2(c) is intended to comply with the minimum gain 
chargeback requirement in Treas. Regs. Section 1.704-2(f) and 
shall be interpreted consistently therewith.

(d) 	Except as otherwise provided in Treas. Regs. 
Section 1.704-2(i)(4), notwithstanding any other provision of 
this Section 5.2, if there is a net decrease in Partner 
Nonrecourse Debt Minimum Gain attributable to a Partner 
Nonrecourse Debt during any Fiscal Year, each Member who has a 
share of the Partner Nonrecourse Debt Minimum Gain attributable 
to such Partner Nonrecourse Debt, determined in accordance with 
Treas. Regs. 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 such 
Member's share of the net decrease in Partner Nonrecourse Debt 
Minimum Gain attributable to such Partner Nonrecourse Debt, 
determined in accordance with Treas. Regs. 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 Member pursuant thereto.  The items to be so allocated 
shall be determined in accordance with Treas. Regs. Sections 
1.704-2(i)(4) and 1.704-2(j)(2).  This Section 5.2(d) is intended 
to comply with the minimum gain chargeback requirement in 
Treas. Regs. Section 1.704-2(i)(4) and shall be interpreted 
consistently therewith.

(e) 	Nonrecourse Deductions for any Fiscal Year shall be 
specially allocated to the Members in the proportions they share 
Net Profits pursuant to Section 5.1(a)(ii).

(f) 	Any Partner Nonrecourse Deductions for any Fiscal Year 
shall be specially allocated to each Member who bears the 
economic risk of loss with respect to the Partner Nonrecourse 
Debt to which such Partner Nonrecourse Deductions are 
attributable in accordance with Treas. Regs. 
Section 1.704-2(i)(1).

(g) 	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 Treas. Regs. Section 
1.704-1(b)(2)(iv)(m)(2) or Section 1.704-1(b)(2)(iv)(m)(4), to be 
taken into account in determining Capital Accounts as the result 
of a distribution to a Member in complete liquidation of its 
interest in the Company, 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 Member in accordance with its interests in the 
Company in the event that Treas. Regs. Section 1.704-
1(b)(2)(iv)(m)(2) applies, or to the Member to whom such 
distribution was made in the event that Treas. Regs. 
Section 1.704-1(b)(2)(iv)(m)(4) applies.

(h) 	The allocations set forth in Sections 5.1(b)(ii), 
5.2(a), 5.2(b), 5.2(c), 5.2(d), 5.2(e), 5.2(f), and 5.2(g) (the 
"Regulatory Allocations") are intended to comply with certain 
requirements of the Treasury Regulations.  It is the intent of 
the Members that, to the extent possible, all Regulatory 
Allocations shall be offset either with other Regulatory 
Allocations or with special allocations of other items of Company 
income, gain, loss or deduction pursuant to this Section 5.2(h). 
 Therefore, notwithstanding any other provision of this Article V 
(other than the Regulatory Allocations), the Members Committee 
shall make such offsetting special allocations of Company income, 
gain, loss or deduction in whatever manner they determine 
appropriate so that, after such offsetting allocations are made, 
each Member's Capital Account balance is, to the extent possible, 
equal to the Capital Account balance such Member would have had 
if the Regulatory Allocations were not part of the Agreement and 
all Company items were allocated pursuant to Sections 5.1(a) and 
5.1(b).  In exercising their discretion under this 
Section 5.2(h), the Members Committee shall take into account 
future Regulatory Allocations under Sections 5.2(c) and 5.2(d) 
that, although not yet made, are likely to offset other 
Regulatory Allocations previously made under Sections 5.2(e) and 
5.2(f).

(i) 	For purposes of determining the Net Profits, Net 
Losses, or any other items allocable to any period, Net Profits, 
Net Losses, and any such other items shall be determined on a 
daily, monthly, or other basis, as determined by the Members 
Committee using any permissible method under Code Section 706 and 
the Treasury Regulations thereunder.

(j) 	The Members are aware of the income tax consequences of 
the allocations made by this Article V and hereby agree to be 
bound by the provisions of this Article V in reporting their 
shares of Company income and loss for income tax purposes.

(k) 	Solely for purposes of determining a Member's 
proportionate share of the "excess nonrecourse liabilities" of 
the Company within the meaning of the Treas. Regs. Section 
1.752-3(a)(3), each Member's interest in the Company's profits 
shall be such Member's Company Interest.

(l) 	To the extent permitted by Treas. Regs. Section 
1.704-2(h)(3), the Members shall endeavor to treat distributions 
as having been made from the proceeds of a Nonrecourse Liability 
or a Partner Nonrecourse Debt only to the extent that such 
distributions would cause or increase an Adjusted Deficit Capital 
Account for any Member.

(m) 	In accordance with Code Section 704(c) 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 Members 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 method described in 
Treas. Reg. Sec. 1.704-3(c).

	The Gross Asset Value of property other than goodwill 
initially contributed to capital of the Company shall equal such 
property's adjusted tax basis for Federal income tax purposes as 
of January 1, 1996.  The Gross Asset Value of goodwill 
contributed to the capital of the Company by each Member shall 
equal the excess of the value attributed to such Member's initial 
Capital Contribution in Section 3.1 of this Agreement (increased 
by liabilities of the Member assumed by the Company) over the 
Gross Asset Value of property other than goodwill contributed by 
the Member.  Goodwill shall be recovered by the Company over 10 
years using the straight-line method.  The tax departments of HSB 
and TDCC shall integrate the property systems of Radian and DEI 
and shall calculate the Gross Asset Value of goodwill contributed 
by the Members within sixty (60) days of the Closing Date.

	In the event the Gross Asset Value of any Company asset is 
adjusted pursuant to paragraph (ii) of the definition thereof, 
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 manner provided in Treas. Regs. 
Section 1.704-3(a)(6).

	Any elections or other decisions relating to such 
allocations shall be made by the Tax Matters Partner in any 
manner that reasonably reflects the purpose and intention of this 
Agreement.  Allocations pursuant to this Section 5.2(m) are 
solely for purposes of Federal, state, and local taxes and shall 
not affect, or in any way be taken into account in computing, any 
Member's Capital Account or share of Net Profits, Net Losses, 
other items, or distributions pursuant to any provision of this 
Agreement.

(n) 	Gross income attributable to corporations in which the 
Company owns an interest shall be allocated in the following 
priority:

		(i)   gross income attributable to dividends received 
by the Company from its subsidiaries after December 31, 1999 
shall be allocated to the Members in proportion to their 
Company Interests as of December 31, 1999, until the amount 
of gross income allocated with respect to such dividends 
from each such subsidiary pursuant to this clause (i) equals 
the net increase, if any, in the retained earnings and 
profits (for U.S. tax purposes) of the distributing 
subsidiary for the four-year period ending December 31, 1999 
to the extent such earnings and profits were not included in 
the Net Profits of the Company for such four-year period; 
and

		(ii)	 all other gross income resulting from any 
dividends or resulting from the application of Code 
Section 951 shall be included in Net Profits and allocated 
pursuant to Section 5.1.

(o) 	For each of the years 1996 and 1997 respectively, if 
the Net Profits allocated to Radian pursuant to Section 5.1(a) 
for such year are less than the lesser of Preferred Accounting 
Earnings for such year or Accounting Earnings for such year, then 
Radian shall be allocated an amount of gross income so that the 
net amount of Net Profits, Net Losses and gross income allocated 
to Radian at least equals the lesser of Preferred Accounting 
Earnings for such year or Accounting Earnings for such year. 

(p) 	DEI shall be allocated an aggregate amount of gross 
income pursuant to this Section 5.2(p) such that the net amount 
of Net Profits, Net Losses and gross income allocable to DEI 
exceeds the amount that would be allocated to it without taking 
this Section 5.2(p) into account by an amount equal to 40% of the 
amount by which the Net Profits, Net Losses and gross income 
allocated to Radian was increased pursuant to Section 5.2(o).  
The amount allocated pursuant to this Section 5.2(p) shall not 
exceed 40% of the sum of the following amount calculated for 1996 
plus the following amount calculated for 1997: the excess, if 
any, of (i) the lesser of Preferred Accounting Earnings or 
Accounting Earnings over (ii) 100% of Net Profits.  Such amount 
shall be allocated to DEI ratably over a five-year period 
beginning in 1998.

V.3   Expenses of the Company.  All of the Company 
expenses shall be billed directly to and paid by the Company.  
The Company is specifically authorized to make reimbursements to 
any Member that provides goods, materials or services used for or 
by the Company provided such are authorized in advance in writing 
and are in accordance with the Company's annual budget.  In no 
event shall any amount charged to the Company as a reimbursable 
expense by any Member exceed the amount that the Company would be 
required to pay to independent parties for comparable goods, 
materials or services.  Reimbursement for expenses shall be made 
to any Member entitled to such reimbursement regardless of 
whether any distributions are made to the Members under the 
provisions of this Article V.

V.4   Distributions. 

	(a)	Except as provided in Sections 5.6 and 9.6, 

		(i)   and except as provided in clauses (ii) and (iii) 
below, all distributions of cash and/or other Property shall 
be made to the Members pro rata in proportion to the 
respective Company Interest of the Members on the record 
date of the distribution, 

		(ii)  and except as provided in clause (iii) below, 
distributions of cash or other Property, the record date of 
which is after December 31, 1999, shall continue to be 
distributed to the Members pro rata in proportion to the 
respective Company Interest of the Members as of 
December 31, 1999, until an aggregate amount of cash or 
other Property has been distributed pursuant to 
Section 5.4(a)(i), this Section 5.4(a)(ii) and Section 5.6 
equal to 80% of the sum of (A) the excess of the Net Profits 
allocated pursuant to Section 5.1 over the Net Losses 
allocated pursuant to Section 5.1 and (B) the excess of any 
items in the nature of income or gain which were specially 
allocated pursuant to Section 5.2 over any items in the 
nature of deduction or loss that were allocated pursuant to 
Section 5.2 (other than allocations solely for tax purposes 
pursuant to Section 5.2(m)), in the case of (A) and (B), 
with respect to periods ending before January 1, 2000, and 

		(iii) distributions of cash or other Property, the 
record date of which is after December 31, 1999, shall be 
distributed to the Members pro rata in proportion to the 
respective Company Interest of the Members as of 
December 31, 1999, until the aggregate amount of cash or 
other Property distributed pursuant to this clause (iii) 
equals 80% of the aggregate amount of gross income allocated 
pursuant to Section 5.2(n)(i) of this Agreement after 
December 31, 1999 (net of deemed taxes treated as a dividend 
received under Code Section 78). 

	(b)	Except as provided below and in Section 5.5, 
distributions of Net Cash Flow and Property shall be made 
whenever such distributions are permitted under the Company's 
strategic business plan.  The Members presently intend to operate 
the Company to maximize distributions by the Company to the 
Members, to the extent consistent with prudent operation of the 
Company, while permitting the Company to retain sufficient 
capital resources for the rapid growth of the Company in 
accordance with its strategic business plan; provided, however, 
that no distribution shall be made if in the sole discretion of 
the Members Committee such proposed distribution would materially 
impair the ability of the Company to comply with its strategic 
business plan or the amount of such distribution is needed for 
the operations of the Company.  

	(c)	All amounts withheld pursuant to the Code or any 
provisions of state or local tax law from any payment or 
distribution to the Members from the Company shall be treated as 
amounts distributed to the relevant Member or Members pursuant to 
this Section 5.4.  

	(d)	Notwithstanding anything to the contrary in this 
Agreement, no distribution shall be made to a Member if such 
Member has an Adjusted Deficit Capital Account, or if such 
distribution would cause such Member to have an Adjusted Deficit 
Capital Account, but such undistributed amounts shall be 
distributed to such Members as soon as and to the extent that 
such distributions can be made without causing such Member to 
have an Adjusted Deficit Capital Account.

V.5   Limitation Upon Distributions.  Distributions shall be 
declared or paid only if, after giving effect to the 
distribution, the assets of the Company are in excess of all 
liabilities of the Company, except liabilities to Members on 
account of their contributions and liabilities for which the 
recourse of creditors is limited to specified Property of the 
Company.  The fair value of Property that is subject to a 
liability for which the recourse of creditors is limited shall be 
included in the assets of the Company only to the extent the fair 
value of that Property exceeds that liability.  Notwithstanding 
the foregoing, except as provided in Section 5.6, it is the 
current expectation of the Members that no distribution shall be 
declared or paid prior to January 1, 1999, and then only if such 
distribution is in compliance with this Section 5.5.

V.6   Distributions to Cover Taxes.  The Company shall make 
the following distributions of cash:

(a) 	by April 15th of each year, the Company shall 
distribute to each Member cash pursuant to this Section 5.6(a) so 
that the total amount of cash and/or other Property distributed 
to such Member pursuant to any provision of this Article 5 other 
than Section 5.6(e) since January 1 of such year at least equals 
the product of (i) such Member's Company Interest for such year, 
multiplied by (ii) the highest marginal federal income tax rate 
effective for corporations as of January 1 of such year, 
multiplied by (iii) the total projected federal taxable income to 
be reported by the Company with respect to such year, multiplied 
by (iv) 25%; provided, that this Section 5.6(a) shall not apply 
to DEI for the years 1996 or 1997.

(b) 	by June 15th of each year, the Company shall distribute 
to each Member cash pursuant to this Section 5.6(b) so that the 
total amount of cash and/or other Property distributed to such 
Member pursuant to any provision of this Article 5 other than 
Section 5.6(e) since January 1 of such year at least equals the 
product of (i) such Member's Company Interest for such year, 
multiplied by (ii) the highest marginal federal income tax rate 
effective for corporations as of January 1 of such year, 
multiplied by (iii) the total projected federal taxable income to 
be reported by the Company with respect to such year, multiplied 
by (iv) 50%; provided, that this Section 5.6(b) shall not apply 
to DEI for the years 1996 or 1997.

(c) 	by September 15th of each year, the Company shall 
distribute to each Member cash pursuant to this Section 5.6(c) so 
that the total amount of cash and/or other Property distributed 
to such Member pursuant to any provision of this Article 5 other 
than Section 5.6(e) since January 1 of such year at least equals 
the product of (i) such Member's Company Interest for such year, 
multiplied by (ii) the highest marginal federal income tax rate 
effective for corporations as of January 1 of such year, 
multiplied by (iii) the total projected federal taxable income to 
be reported by the Company with respect to such year, multiplied 
by (iv) 75%; provided, that this Section 5.6(c) shall not apply 
to DEI for the years 1996 or 1997.

(d) 	by December 15th of each year, the Company shall 
distribute to each Member cash pursuant to this Section 5.6(d) so 
that the total amount of cash and/or other Property distributed 
to such Member pursuant to any provision of this Article 5 other 
than Section 5.6(e) since January 1 of such year at least equals 
the product of (i) such Member's Company Interest for such year, 
multiplied by (ii) the highest marginal federal income tax rate 
effective for corporations as of January 1 of such year, 
multiplied by (iii) the total projected federal income tax to be 
reported by the Company with respect to such year; provided, that 
this Section 5.6(d) shall not apply to DEI for the years 1996 or 
1997.

(e) 	Each year, within ten (10) days after the time the 
Internal Revenue Service Form 1065 Schedule K-1 is delivered to 
the Members, the Company shall distribute cash to each Member 
pursuant to this Section 5.6(e) in an amount equal to any excess 
of (i) the product of (A) the taxable income allocated to such 
Member as shown on the Internal Revenue Service Form 1065 
Schedule K-1 delivered to such Member with respect to the 
previous year, multiplied by (B) the highest marginal federal 
income tax rate effective for corporations on income earned in 
the previous year (blended if necessary to reflect any change in 
the highest marginal rate), over (ii) the total amount of cash 
and/or other Property distributed to such Member pursuant to any 
provision of this Article 5 other than Section 5.6(e) during the 
previous year. 


ARTICLE VI 

MANAGEMENT RIGHTS, DUTIES AND POWERS OF THE REPRESENTATIVES

VI.1   Management.  (a)  It shall be the duty and 
responsibility of the Members Committee solely and exclusively to 
manage and control the business and affairs of the Company, and, 
subject to Section 6.10, all decisions regarding the business and 
affairs of the Company shall be made by the Members Committee.  
Except as provided in this Agreement, each Representative shall 
have all the rights and powers of a Representative as provided in 
the Act and as otherwise provided by law, and any action taken by 
a Representative in the manner provided for in this Agreement 
shall constitute the act of and serve to bind the Company.  The 
Members Committee may delegate its authorities and responsibi-
lities for management of the business affairs of the Company to 
third parties, but such delegation shall not relieve the Members 
Committee of any of its obligations under this Agreement.  In 
furtherance of this right of delegation, the Members Committee 
may appoint and authorize officers of the Company to act on 
behalf of the Company with such power and authority as the 
Members Committee may delegate in writing to such Member.  The 
initial officers of the Company, and their duties, are set forth 
on Schedule 6.1 to this Agreement.  Subject to Section 6.10, the 
Members Committee is hereby granted (i) the right, power and 
authority to do on behalf of the Company all things which, in its 
judgment, are necessary, proper or desirable to carry out the 
aforementioned duties and responsibilities, including but not 
limited to the right, power and authority from time to time to 
incur Company expenses; to employ and dismiss from employment any 
and all employees, agents, independent contractors, attorneys and 
accountants; to establish employee benefits plans; to enter into 
leases for real or personal property; to purchase equipment; and 
to manage all other aspects of running the business of the 
Company all in accordance with any authorization policy adopted 
by the Members Committee; and (ii) such other rights, powers and 
authorities of a manager as provided in the Act and as otherwise 
provided by law.

(a) 	Except as set forth in Section 6.10, the Members 
Committee shall retain the decision-making authority for the 
Company.  Notwithstanding the foregoing, it is the express 
intention of the Members that the Members Committee manage the 
affairs of the Company so as to achieve, to the extent consistent 
with prudent operation of the Company, the Preferred Accounting 
Earnings for each of Fiscal Years 1996 and 1997.  

VI.2   No Management by Members.  Except as otherwise 
provided in this Agreement, no Member shall take part in the day-
to-day management, or the operation or control of the business 
and affairs of the Company.  Except as expressly delegated by the 
Members Committee, no Member shall be an agent of the Company or 
have any right, power or authority to transact any business in 
the name of the Company or to act for or on behalf of the 
Company.

VI.3   Number, Qualification and Tenure of Representatives.  
The Members Committee shall have as few as three and as many as 
eleven members, as established from time to time by resolution of 
the Members Committee.  Initially the Members Committee shall 
consist of seven (7) members, four (4) of whom shall be DEI 
Representatives and three (3) of whom shall be Radian 
Representatives.  If the Members Committee shall increase or 
decrease the number of members on the Members Committee, then the 
composition of the Members Committee of DEI and Radian 
Representatives shall as closely as possible reflect the Member's 
respective Company Interest at that time; provided, however, 
that, at all times, there shall be a majority of DEI 
Representatives on the Members Committee.  All DEI 
Representatives on the Members Committee shall be employees of 
DEI or one or more of its Affiliates, and all Radian 
Representatives on the Members Committee shall be employees of 
Radian or its Affiliates.  A DEI Representative shall serve as 
Chair of the Members Committee.  DEI and Radian shall, within ten 
(10) days of the date of this Agreement, notify each other in 
writing of the identity of the DEI Representatives and the Radian 
Representatives, respectively.  DEI, within ten (10) days of the 
date of this Agreement, shall notify Radian in writing as to 
which of its DEI Representatives is to initially serve as Chair 
of the Members Committee.  Any Representative shall continue to 
serve in such capacity until such Member shall have notified the 
other Members in writing of his or her replacement.  DEI and 
Radian may, by written notice to the other, designate a person to 
serve as an alternate for each DEI Representative and each Radian 
Representative, respectively (each alternate to a DEI Representa-
tive being referred to in this Agreement as a "DEI Alternate" 
and, collectively, as the "DEI Alternates"; each alternate to a 
Radian Representative being referred to in this Agreement as a 
"Radian Alternate" and, collectively, as the "Radian Alternates"; 
and the DEI Alternates and the Radian Alternates being 
collectively referred to in this Agreement as the "Alternates"), 
and such DEI Alternate or Radian Alternate, as the case may be, 
shall be entitled, in the absence of such DEI Representative or 
Radian Representative, to attend meetings, to have such 
Alternate's presence counted for purposes of establishing a 
quorum and to vote on behalf of such DEI Representative or Radian 
Representative at any meeting of the Members Committee.  Each 
Member, in dealing with DEI Representatives or Alternates or the 
Radian Representatives or Alternates, as the case may be, shall 
be entitled to rely conclusively upon the power and authority of 
such Representatives or Alternates to bind DEI or Radian, as the 
case may be, with respect to all matters unless and until it 
receives notice to the contrary in writing from DEI or Radian, as 
the case may be.  To the fullest extent permitted by law, each 
Representative and Alternate shall be deemed the agent of the 
Member which appointed such Person a Representative or Alternate, 
and such Representative or Alternate shall not be deemed an agent 
or a sub-agent of the Company or the other Members and shall have 
no duty (fiduciary or otherwise) to the Company or the other 
Members.  Each Member, by execution of this Agreement, agrees to, 
consents to, and acknowledges the delegation of powers and 
authority to such Representatives and Alternates, and the actions 
and decisions of such Representatives and Alternates within the 
scope of their respective authority as provided in this 
Agreement.

VI.4   Meetings.  The Members Committee shall hold regular 
meetings at least once during each Fiscal Year on such date or 
dates as specified by the Members Committee.  Other regular 
meetings shall be held at such time and at such place as shall 
from time to time be determined by the Members Committee.  
Meetings of the Members Committee may be held by conference 
telephone or other means of communication by means of which all 
participants can hear each other.  Participation in such meeting 
in such manner shall constitute attendance and presence in person 
at the meeting of the person or persons so participating.  No 
notice of the regular annual meeting need be given.  Special 
meetings of the Members Committee may be called by the Chairman 
of the Members Committee or by any Member on at least two (2) 
business days' notice to the other Member.  Attendance by any DEI 
Representative or Radian Representative or any DEI Alternate or 
Radian Alternate at any meeting of the Members Committee shall 
constitute an effective waiver of any required prior notice to 
DEI or Radian, as the case may be, of such meeting, unless such 
attendee declares at the onset of such meeting that such 
attendee's attendance at such meeting is solely for the purpose 
of contesting the deficiency of any required notice for the 
meeting.  The Chairman of the Members Committee shall, (i) with 
reasonable advance notice (which in the case of regular meetings 
shall not be less than five (5) days), prepare and distribute an 
agenda for each meeting of the Members Committee, (ii) organize 
and conduct such meeting and (iii) prepare and distribute minutes 
of such meeting.  Any Member may propose in advance topics for 
the agenda or, subject to Section 6.5, raise topics which are not 
on the agenda for such meeting.   Each Representative or 
Alternate of each of DEI and Radian may bring one or more other 
advisors to any meeting; provided, that such advisors shall not 
have the right to vote on any matter brought before the Members 
Committee; and provided further, that the Representatives or 
Alternates of either of DEI or Radian shall have the right to 
call executive sessions of the Members Committee and to exclude 
any Person not a Representative or Alternate from such executive 
session.   

VI.5   Quorum and Voting.  Meetings of the Members Committee 
may only be held when a quorum is present (whether present in 
person or by telephone or other means of telecommunication).  A 
quorum of the Members Committee shall be comprised of a majority 
of Representatives or Alternates (or any combination thereof in 
accordance with Section 6.4) of the full Members Committee as 
constituted pursuant to Section 6.3 of this Agreement of which at 
least a majority of such majority must be DEI Representatives or 
DEI Alternates; provided, however, that if a Radian 
Representative or Radian Alternate is not present at any meeting 
of the Members Committee then, at such meeting, only such 
business as set forth on the agenda for such meeting may be 
considered and voted upon.  The affirmative vote of a majority of 
the Members Committee at a meeting at which a quorum is present 
being entitled to vote at any such meeting must be obtained in 
connection with the decision of any matter being considered by 
the Members Committee.  If a quorum is not present, the 
Representatives and Alternates present may adjourn the meeting 
without notice, other than an announcement at the meeting, until 
a quorum shall be present.

VI.6   Committees.  The Members Committee may appoint from 
among its members an Executive Committee, an Audit Committee, a 
Compensation Committee and other committees, composed of two or 
more Representatives (one of which must be a Radian 
Representative or Radian Alternate), to serve at the pleasure of 
the Members Committee.  Except as expressly limited by applicable 
law or this Agreement, each such committee shall exercise such 
powers and authority as the Members Committee may determine and 
specify in a writing designating such committee or any amendment 
thereto.  Unless otherwise specified in the writing designating 
the committee, a majority of the members of such committee may 
elect its Chair, fix its rules of procedure, fix the time and 
place of meetings and specify what notice of meetings, if any, 
shall be given.  Written records of the proceedings of any 
committee shall be maintained and furnished to the Members 
Committee.

VI.7   Action Without Meeting.  Any action required or 
permitted to be taken at a meeting of the Members Committee, or 
of any committee thereof, may be taken without a meeting if all 
members of the Members Committee, or committee thereof, consent 
in writing to such action.

VI.8   Compensation.  The Members Committee shall not receive 
any compensation, but shall be reimbursed by the Company for 
reasonable expenses associated with attendance at meetings.

VI.9   Rules of Procedure.  The Members Committee may from 
time to time adopt detailed rules and procedures not inconsistent 
with this Agreement for the management of the business of the 
Company.

VI.10   Certain Transactions.

(a) 	Except as otherwise set forth in this Agreement, the 
Company shall not engage in any of the following actions without 
the prior affirmative vote of a majority of the Members Committee 
present at a meeting, which majority shall include at least one 
Radian Representative or Radian Alternate:

(i)     the dissolution or winding-up of the Company; 
provided, however, that nothing in this Section 6.10(a)(i) 
shall be construed to conflict with the requirement in 
Section 9.1(a) of this Agreement that a Bankruptcy of any 
Member shall cause the dissolution of the Company;

(ii)   the sale by the Company of any Company Interests 
or derivative rights relating to such Company Interests;

(iii)   changing the nature of the business conducted by 
the Company or conducting any activity that is outside the

Section 2.3, or otherwise in contravention of this 
Agreement;

Formation of the Company;

(v)    prior to January 1, 1999, any change in the 
accounting policies or procedures of the Company set forth 
on Schedule 6.10(a)(v), except for any such changes in 
accounting policies and procedures required by reason of a 
concurrent change in GAAP, government cost accounting 
standards or other applicable governmental requirements; 

(vi)	  (A) the amendment or modification of the 
transfer pricing provision in any contract between the 
Company and TDCC or any of TDCC's Affiliates as of the 
Closing Date or (B) the entry into any contract between the 
Company or any Subsidiary of the Company, on the one hand, 
and any Member or any of its Affiliates, on the other hand, 
except as a result of a competitive bidding process or on 
terms substantially similar to, or more favorable to the 
Company or such Subsidiary than, those that could be entered 
into by the Company in a similar transaction with 
unaffiliated third parties;

(vii)  amending the Company's policy regarding earnings 
distributions to Members or the declaration of dividends;

(viii) the purchase or other acquisition of another 
business; provided, however, that such consent shall not be 
required if the aggregate payments involved in such 
transaction and in all such transactions during the previous 
12-month period do not require an additional capital 
contribution by Radian in excess of $10 million; or

(ix)   sell all, or substantially all, of the Company's 
assets or enter into any other arrangement in which the 
Company's business is transferred to a third party.

In connection with any of the proposed actions set forth in this 
Section 6.10(a), the officers of the Company shall keep the 
Members Committee informed of the Company's business activities 
and provide, or cause to be provided, to the Members Committee 
such information as may be reasonably necessary for the Members 
Committee to make a prudent judgment to approve or disapprove the 
proposed action.

(b) 	The Members Committee shall keep the Members informed 
of the Company's business activities.  In addition to providing 
the periodic reports required by Section 7.1 of this Agreement, 
the Members Committee shall promptly advise, or cause to be 
advised, the Members of any material developments in the 
Company's business, including, without limitation, prior notice 
of the terms and conditions of proposed significant investments, 
acquisitions or dispositions, or other significant transactions 
involving the Company.

(c) 	Except as otherwise provided hereunder or required 
under the Act, whenever it is stated in this Agreement, including 
without limitation, this Section 6.10, that an action of the 
Company or of the Members Committee on behalf of the Company or 
any other action under this Agreement requires the consent or 
agreement of or waiver by the Members, such action shall require 
the consent or agreement of each Member.

VI.11   Right to Rely on Authority of the Representatives.  
Any action taken by the Representatives in their capacity as 
such, acting on behalf of the Company pursuant to the authority 
conferred on them in this Agreement, shall be binding on the 
Company.  In no event shall any Person dealing with the 
Representatives with respect to the conduct of the affairs of the 
Company be obligated to ascertain that the terms of this 
Agreement have been complied with, or be obligated to inquire 
into the necessity or expediency of any act or action of the 
Representatives.  Every contract, agreement, promissory note or 
other instrument or document executed by a Representative with 
respect to any property of the Company or the conduct of its 
affairs, in his/her capacity as a Representative acting on behalf 
of the Company pursuant to the authority conferred on him/her in 
this Agreement, shall be conclusive evidence in favor of any and 
every Person relying thereon or claiming under this Agreement 
that (i) at the time of the execution and/or delivery of such 
instrument or document, this Agreement was in full force and 
effect, (ii) such instrument or document was duly executed in 
accordance with the terms and provisions of this Agreement and is 
binding upon the Company, and (iii) the Representative was duly 
authorized and empowered to execute and deliver any and every 
such instrument or document for and on behalf of the Company.  
Nothing set forth in this Section 6.11 shall be construed as 
relieving the Representatives from liability to the Company or 
the Members for breach of any of the provisions of this 
Agreement, or for acting or failing to act in such manner as 
constitutes an exception from indemnification provisions 
contained in Section 6.13.

VI.12   Responsibility of Members and Representatives.  No 
Member or Representative (or their Affiliates) shall have any 
fiduciary or other duty or responsibility to the Company, or to 
any other Member or Representative (or their Affiliates), except 
as expressly provided in this Agreement or for acts or omissions 
that constitute willful misconduct or constitute an intentional 
criminal act.  No Representative or Alternate shall be liable to 
the Company or any Member or other Representative or Alternate 
(or their Affiliates) because of a decision by the Members 
Committee to have the Company engage in, or not engage in, a 
particular business, activity or project.

VI.13   Indemnification.  (a)  The Company shall indemnify, 
to the full extent permitted by the laws of the State of 
Delaware, any person who was or is a defendant or is threatened 
to be made a defendant to any threatened, pending or completed 
action, suit or proceeding, whether civil, criminal, 
administrative or investigative, by reason of the fact that such 
person (i) is or was a Member, Representative, Alternate, 
officer, employee or agent of the Company, or (ii) is or was a 
Member, Representative, Alternate, officer, employee or agent of 
the Company and is or was serving at the request of the Company 
as a Member, Representative, Alternate, director, officer, 
employee or agent of another corporation, limited liability 
company, partnership, joint venture, trust or other enterprise, 
against expenses (including attorneys' fees), judgments, fines 
and amounts paid in settlement actually and reasonably incurred 
by such person in connection with such action, suit or 
proceeding, provided that the commission or omission which formed 
the basis of such action, suit or proceeding does not constitute 
gross negligence or willful misconduct or constitute an 
intentional criminal act on the part of such person.  Any repeal, 
amendment or modification of this Section 6.13 shall not affect 
any rights or obligations then existing between the Company and 
any then incumbent or former Member, Representative, Alternate, 
officer, employee or agent with respect to any state of facts 
then or theretofore existing or any action, suit or proceeding 
theretofore or thereafter brought based in whole or in part upon 
such state of facts.

(a) 	Expenses incurred by any current or former Member, 
Representative, Alternate, officer, employee or agent in 
defending or investigating a threatened or pending action, suit 
or proceeding shall be paid by the Company in advance of the 
final disposition of such action, suit or proceeding, upon 
receipt of an undertaking by or on behalf of the Member, 
Representative, Alternate, officer, employee or agent to repay 
such amount if it ultimately shall be determined that the Member, 
Representative, Alternate, officer, employee or agent is not 
entitled to be indemnified by the Company as authorized in this 
Section 6.13.

(b) 	The indemnification and advancement of expenses 
mandated or permitted by, or granted pursuant to, this 
Section 6.13 shall not be deemed exclusive of any other rights to 
which those seeking indemnification or advancement of expenses 
may be entitled under any agreement, contract, vote of Members or 
disinterested Representatives (or Alternates) or pursuant to the 
direction (howsoever embodied) of any court of competent 
jurisdiction or otherwise both as to action by the person in an 
official capacity and as to action in another capacity while 
holding such office.  The provisions of this Article VI shall not 
be deemed to preclude the indemnification of any person who is 
not specified in subsections (a) and (b) above, but whom the 
Company has the power or obligation to indemnify under the laws 
of the State of Delaware or otherwise.

(c) 	The Company may purchase and maintain insurance on 
behalf of any person who is or was a Member, Representative, 
Alternate, officer, employee or agent of the Company, or is or 
was serving at the request of the Company as a Member, 
Representative, Alternate, director, officer, employee or agent 
of another corporation, limited liability company, partnership, 
joint venture, trust or other enterprise against any liability 
asserted against and incurred by such person in any such 
capacity, or arising out of the person's status as such, whether 
or not the Company would have the power or the obligation to 
indemnify such person of the Company against such liability under 
the provisions of this Section 6.13.

(d) 	The indemnification and advancement of expenses 
provided by, or granted pursuant to, this Section 6.13 shall 
continue as to a person who has ceased to be a Member, 
Representative, Alternate, officer, employee or agent of the 
Company and shall inure to the benefit of the heirs, executors 
and administrators of such person.

VI.14   Designation of Tax Matters Partner; Expenses 
Regarding Tax Matters; Filing of Tax Returns.

(a) 	DEI is hereby designated as the "Tax Matters Partner" 
under Section 6231(a)(7) of the Code.  During any Company income 
tax audit or other income tax controversy with any governmental 
agency, the Tax Matters Partner shall keep the Members informed 
of all material facts and developments on a timely basis, and 
shall consult with the Members at their request.  The Tax Matters 
Partner shall not be authorized to enter into a settlement which 
binds the Members or the Company  without the advance written 
consent of the Member, except for settlements for de minimis 
amounts (e.g., not exceeding $100,000 in the aggregate).  The Tax 
Matters Partner shall take all actions necessary to cause each 
qualifying Member to be a "notice partner" within the meaning of 
Sections 6223(a) and 6231(a)(8) of the Code.

(b) 	All reasonable expenses incurred by the Tax Matters 
Partner with respect to any tax matter which does or may affect 
the Company, or any Member by reason thereof, including but not 
limited to expenses incurred by the Tax Matters Partner acting in 
its capacity as Tax Matters Partner in connection with Company-
level administrative or judicial tax proceedings, shall be paid 
for out of Company assets.  If the Members are permitted by the 
Company or permitted under the Code to participate in Company-
level administrative or judicial tax proceedings, the Company 
shall be responsible for all expenses incurred by them in 
connection with such participation.  The cost of any adjustments 
to the Members and the cost of any resulting audits or adjust-
ments of the Members' tax returns will be borne solely by the 
Members and the cost of any adjustments to the Company and the 
cost of any resulting audits or adjustments of the Company's tax 
returns will be borne solely by the Company.

(c) 	The Tax Matters Partner shall prepare and timely file 
all tax returns of the Company.  The Company shall reimburse the 
Tax Matters Partner for the reasonable costs of preparing and 
filing the tax returns of the Company.

	Within eight (8) business days after the last day of each

lapse of time or both, would constitute an event of default under 
any indebtedness of the Company.  The Members Committee shall 
also prepare and distribute, or cause to be prepared and dis-
tributed, to each Member within forty-five (45) days after the 
end of each fiscal year, or as soon thereafter as is practicable, 
a report with respect to the Company which includes the items set 
forth in (i), (ii) and (iii) of the foregoing sentence with 
respect to such fiscal year.  Such annual report shall be audited

if qualified, shall state the basis for such qualification).  The 
Members Committee shall also use its reasonable best efforts to 
cause the auditors to provide an annual earnings clearance within 
fifteen (15) days after the end of each fiscal year.  The costs 
of any audits or earnings clearances shall be an expense of the 
Company.

	The Members Committee shall also engage, or cause to be

ARTICLE VIII 

TRANSFER OF COMPANY INTEREST; 
RADIAN OPTION TO SELL; LIENS  

VIII.1   Transfer of Company Interest Generally.  No Member 
may assign, transfer or otherwise dispose of all or any portion 
of its Company Interest except in accordance with the terms of 
this Article VIII.  Any attempt by any Member to assign, transfer 
or otherwise dispose of all or any portion of its Company 
Interest other than in accordance with this Article VIII shall be 
null, void ab initio and of no force and effect.

VIII.2   Transfers of Company Interests.  Except as otherwise 
consented to in writing by the other Member (which consent may be 
granted or withheld in the sole and absolute discretion of any 
Member), no Member may sell, transfer or otherwise dispose of 
(collectively a "Transfer") all or any portion of its Company 
Interest.  In addition to such consent, no Member may make such a 
Transfer unless (i) such a Transfer is pursuant to a written 
agreement pursuant to which the transferee agrees to be bound by 
all of the terms of this Agreement as if it were originally a 
party to this Agreement, (ii) such a Transfer does not cause a 
termination of the Company for Federal income tax purposes and 
(iii)  such a Transfer complies with applicable Federal and state 
securities laws.

VIII.3   Radian Option to Sell.  From and including 
December 31, 1997 through December 31, 1998, Radian, at its 
option, upon written notice of not less than thirty (30) days, 
may exercise the sell option set forth in this Section 8.3.  If 
Radian gives the notice referred to in the preceding sentence, 
Radian shall have the right to require DEI to purchase, and the 
obligation to sell all, but not less than all, of Radian's 
Company Interest at a price equal to $131,327,406 plus (i) the 
Earnings Shortfall, (ii) the amount of any then outstanding 
Ordinary Loans or Member Loans made by Radian or any of its 
Affiliates (plus interest thereon), and (iii) any amounts then 
outstanding and owed by the Company to HSB under the loan 
agreement dated as of January 1, 1996 between HSB and Radian (the 
"Loan Agreement") (it being understood that Radian's rights and 
obligations under the Loan Agreement will be assigned at the 
Closing to the Company).  The "Earnings Shortfall" shall equal 
the sum of the Preferred Accounting Earnings for Fiscal Year 1996 
and Fiscal Year 1997 minus the sum of 40% of the Accounting 
Earnings of the Company (which for purposes of this Agreement 
shall never be less than zero) for Fiscal Year 1996 and Fiscal 
Year 1997, respectively; provided, however, that the Earnings 
Shortfall shall not exceed $5,000,000 in the aggregate.  If DEI 
and Radian cannot agree upon the Accounting Earnings of the 
Company within sixty (60) days after the notice referred to in 
the first sentence of this Section 8.3, either DEI or Radian may, 
by notice to the other, invoke the Appraisal Procedure.  If the 
Appraisal Procedure is required to determine the Accounting 
Earnings, the fees and expenses of such Appraisal Procedure shall 
be shared equally by DEI and Radian.  The closing of such sale 
shall take place upon the date that is within fifteen (15) days 
after the later to occur of (i) the determination of the 
Accounting Earnings in accordance with this Section 8.3 and (ii) 
compliance with any applicable legal requirements; provided, 
however, that if such sale is not in compliance with any 
applicable legal requirements, then DEI and Radian shall 
equitably adjust the arrangements set forth in this Section 8.3 
in light of what is legally possible and in compliance with any 
applicable legal requirements in order to effectuate the intent 
of the parties.  Upon the closing of such sale, DEI shall assume 
all obligations under any guarantee provided by Radian or its 
Affiliates pursuant to Section 3.5 of this Agreement in a written 
agreement mutually acceptable to DEI and Radian, and the 
Company's obligations under the Loan Agreement and obligation to 
pay Radian any amounts in connection with any Ordinary Loans or 
Member Loans shall be cancelled.  Notwithstanding any other 
provision of this Agreement, DEI may assign any of its rights and 
obligations under this Section 8.3 to TDCC or any of TDCC's 
Affiliates and Radian may assign any of its rights and 
obligations under this Section 8.3 to HSB or any of HSB's 
Affiliates.

VIII.4   Liens.  No Member may, except with the consent of 
the other Member (which consent may be granted or withheld in 
such Member's sole discretion), create or permit to exist any 
Lien on its Company Interest or any portion thereof (except (i) 
Liens for current taxes not delinquent or taxes being contested 
in good faith and by appropriate proceedings or (ii) Liens 
arising in the ordinary course of business for sums not due or 
sums being contested in good faith and by appropriate 
proceedings).  Any attempt by any Member to create or permit to 
exist any Lien (other than the Liens described in the second 
parenthetical in the immediately preceding sentence) on its 
Company Interest or any portion thereof shall be null, void ab 
initio and of no force and effect.  Notwithstanding anything to 
the contrary contained in this Agreement, if any Person obtains a 
Lien on the Company Interest, or portion thereof, of any Member 
and forecloses on such Lien, (i) the Company shall continue, (ii) 
the Person foreclosing on the Lien shall succeed to the economic 
interests of the Company Interest, or portion thereof, upon which 
it foreclosed but not the voting or other interests which 
comprise such Company Interest, or portion thereof, (iii) the 
Person foreclosing on such Lien shall not be admitted as a 
"Member" without the approval of the Members Committee and the 
consent of the other Members (which consent may be granted or 
withheld in the sole and absolute discretion of each such 
Member), and (iv) any sale or other disposition of the Company 
Interest, or portion thereof, upon which such Person foreclosed 
shall be subject to the terms of Article VIII of this Agreement.


ARTICLE IX 

DISSOLUTION AND WINDING-UP

IX.1   Dissolution.  The Company shall be dissolved upon the 
first to occur of the following events (each, a "Dissolution 
Event"):

(a) 	the Bankruptcy of any Member;

(b) 	the election by the Members to dissolve the Company;

(c) 	the occurrence of any event that makes it unlawful for 
the business of the Company to be carried on or for the Members 
to carry it on as a limited liability company;

(d) 	the entry of a decree of judicial dissolution; or

(e) 	subject to Sections 9.8 and 9.9, the occurrence of any 
other event that, absent an agreement to the contrary, causes a 
dissolution of the Company under the Act;

provided that, except as provided in the Contribution Agreement, 
if a dissolution of the Company is caused by the Bankruptcy of 
any Member (the "Bankrupt Member"), then DEI, if it is not the 
Bankrupt Member or Radian, if it is not the Bankrupt Member (in 
either case, the "Non-Bankrupt Member") may elect to, upon notice 
to the Bankrupt Member, purchase (or have an Affiliate purchase) 
all, but not less than all, of the Bankrupt Member's Company 
Interest at the Purchase Price.  The "Purchase Price" to be paid 
to the Bankrupt Member (by the Non-Bankrupt Member) in any sale 
and purchase of the Bankrupt Member's Company Interest pursuant 
to this Section 9.1 shall be (x) 50% of what the entire Company 
could be sold for multiplied by the Bankrupt Member's Company 
Interest, determined (unless otherwise agreed) in accordance with 
the Appraisal Procedure (which Appraisal Procedure shall be at 
the expense of the Bankrupt Member), reduced by (y) the amount of 
any actual losses, costs, fees, expenses or damages suffered by 
the Company, the Non-Bankrupt Member or any of its Affiliates as 
a result of such dissolution, and shall be payable to the 
Bankrupt Member in five equal annual installments, without 
interest, commencing on the date of the transfer of the Company 
Interest of the Bankrupt Member (which shall be the tenth (10th) 
business day following the determination of the Purchase Price); 
provided, however, that if Radian is the Bankrupt Member and if 
DEI elects to purchase (or have an Affiliate purchase) all of 
Radian's Company Interest on or prior to December 31, 1998, then 
the fair market value of Radian's Company Interest for purposes 
of (x) above shall be equal to the amount set forth in 
Section 8.3 of this Agreement as if Radian had exercised its 
option to sell; provided further, however, that such fair market 
value (prior to the adjustment set forth below) shall be 
discounted at a rate of 10% per year or portion thereof if such 
purchase shall occur prior to December 31, 1997.  In any winding 
up pursuant to Section 9.2 of this Agreement, the amount 
otherwise distributable to the Bankrupt Member pursuant to the 
following provisions of this Article IX shall be reduced by the 
amount of any actual losses, costs, fees, expenses or damages 
suffered by the Company or the Non-Bankrupt Member or any of its 
Affiliates as a result of such dissolution.  Notwithstanding the 
foregoing, if the enforceability of such Non-Bankrupt Member's 
right to purchase the Bankrupt Member's Company Interest as set 
forth above is in any way limited by general equitable 
principles, Bankruptcy, moratorium, or other laws affecting 
creditors' rights generally then, upon notice to the Bankrupt 
Member and the Company, the Non-Bankrupt Member or any of its 
Affiliates shall have the right to purchase from the Company all, 
but not less than all, of the assets and liabilities of the 
Company at the fair market value therefor.  If DEI and Radian 
cannot agree upon such fair market value within sixty (60) days 
after the notice to purchase all the assets and liabilities of 
the Company is delivered, either DEI or Radian may, by notice to 
the other, invoke the Appraisal Procedure.  If the Appraisal 
Procedure is required to determine the fair market value of all 
the assets and liabilities of the Company, the fees and expenses 
of such Appraisal Procedure shall be borne by the Bankrupt 
Member.  The closing of such sale shall take place upon the date 
that is within thirty (30) days after such fair market value is 
determined in accordance with this Section 9.1.  

IX.2   Winding-Up.  Upon dissolution of the Company, and if 
the Non-Bankrupt Member has not made any election pursuant to 
Section 9.1, the Member with the largest Company Interest or, if 
a dissolution of the Company is caused by the Bankruptcy of any 
Member, the Non-Bankrupt Member shall wind up the affairs of the 
Company in accordance with the Act and, to the extent permitted 
by applicable law, shall settle accounts between the Members as 
specified in this Article IX.  The Member charged with winding up 
the affairs of the Company and settling accounts among the 
Members under this Agreement shall be referred to as the 
"Liquidating Member".

IX.3   Accounting on Dissolution.  If the Company is not 
continued in accordance with the terms of this Agreement 
following a dissolution, then on the date (the "Accounting Date") 
which is four (4) months following the date of dissolution, a 
proper accounting shall be made of the Company assets, 
liabilities and operations, from the date of the last previous 
accounting to the Accounting Date.  Any items of income, gain, 
credit, loss, expense and other deductions which are realized 
subsequent to the date of the last previous accounting to the 
Accounting Date shall be allocated in accordance with Article V 
and proper adjustments shall be made to the Capital Account of 
each Member.

IX.4   Accounting; Allocations of Residual Net Profits and 
Residual Net Loss After Dissolutions.

(a) 	Except as provided in Section 9.4(c), any items of gain 
or loss that are realized from Company operations or from sales 
of Company assets subsequent to the Accounting Date and before 
the date of liquidation shall be allocated as provided in 
Article V.

(b) 	Except as provided in Section 9.4(c) and in addition to 
the adjustments to the Member's Capital Accounts described above, 
if any of the Company's assets are to be distributed in kind 
rather than sold, the fair market value of such assets shall be 
determined by the Members and a simulated aggregate gain (if any) 
or loss (if any) for those assets (based upon the difference 
between such fair market value and the Gross Asset Value of such 
assets immediately before such revaluation) shall be allocated to 
the Members' Capital Accounts as that simulated aggregate gain 
(or loss) would have been allocated under Article V if such 
assets had been sold for a cash price equal to each asset's fair 
market value on the Accounting Date.  If DEI and Radian cannot 
agree upon such fair market value within sixty (60) days after 
the Accounting Date, either DEI or Radian may, by notice to the 
other, invoke the Appraisal Procedure.  If the Appraisal 
Procedure is required to determine the fair market value of such 
assets, the fees and expenses of such Appraisal Procedure shall 
be shared equally by DEI and Radian.

(c) 	Prior to the fourth (4th) anniversary of the Closing, 
loss from the sale or deemed sale of assets in conjunction with a 
dissolution pursuant to this Agreement shall be specially 
allocated 100% to DEI; provided, however, that the Losses 
specially allocated pursuant to this Section 9.4(c) shall not 
exceed the Stairstep Loss Cap calculated as of the date of the 
sale or deemed sale giving rise to the Loss.

IX.5   Conversion of Assets to Cash.

(a) 	If the Company Interest of the Bankrupt Member is not 
purchased in accordance with the terms of this Agreement, then 
commencing with the date that is four (4) months after the date 
of dissolution, unless arrangements satisfactory to all Members 
are otherwise made, sufficient assets of the Company will be 
converted into cash to permit the Company to pay all its 
liabilities other than long-term debts which (i) are secured by 
Company assets from which the projected net income is sufficient 
to pay installments of principal and interest on such debts as 
they become due and (ii) contain terms specifying that neither 
the dissolution of the Company nor the distribution of such 
property that is subject to and secured by such debts constitutes 
a default or causes the acceleration of the maturity of such 
indebtedness ("Approved Debts").

(b) 	Notwithstanding the provisions of Sections 9.6 and 9.7 
regarding the method and timing of the liquidation of the assets 
of the Company, but subject to the order of priorities set forth 
in this Agreement, if on commencement of the winding up process 
in accordance with Section 9.2, the Members determine that an 
immediate sale of part or all of the Company's assets would be 
impractical or would cause undue loss to the Members, the Members 
may defer for a reasonable time the liquidation of any assets 
except those necessary to satisfy the liabilities of the Company.

(c) 	In the event that Company assets are distributed in 
kind pursuant to Section 9.4(b), the Members shall be consulted 
to determine the most tax-efficient manner to make such 
distribution, consistent with the liquidation priorities of 
Section 9.6.

IX.6   Distributions in Liquidation.  As soon as the actions 
required by Sections 9.3, 9.4 and 9.5 have been completed, the 
Liquidating Member shall cause the cash and assets of the Company 
to be distributed in the following order:

(a) 	To creditors of the Company (other than Members) in 
payment of all liabilities of the Company (other than Approved 
Debts) in the order of priority as provided by law.  If any 
liability is contingent or uncertain in amount, a reserve equal 
to the maximum amount to which the Company could reasonably be 
held liable will be established.  Upon the payment or other 
discharge of such liability, the amount remaining in such reserve 
not needed, if any, will be distributed in accordance with the 
remaining provisions of this Section 9.6.

(b) 	To the Members in payment of all Member Loans and any 
interest thereon in accordance with the amount owing to each 
Member.

(c) 	To the Members in payment of all loans other than 
Member Loans (including, without limitation, any Ordinary Loans) 
and any interest thereon in accordance with the amount owing to 
each Member.

(d) 	To each Member in accordance with the positive balance 
in its Capital Account, as set forth in Section 9.7.

(e) 	Notwithstanding the foregoing provisions of this 
Section 9.6 and the provisions of Article V, any distribution 
which would be payable to a Member whose actions in violation of 
this Agreement caused the dissolution of the Company shall be 
reduced by the amount of losses, costs, fees, expenses and 
damages suffered by the Company or any Member or its Affiliates 
(other than the Member whose actions caused a dissolution) as a 
result of such dissolution, and a corresponding allocation of Net 
Losses or gross deductions shall be made to such Member.

IX.7   Compliance with Treasury Regulations.  In the event 
that the Company or any Member's Company Interest is "liquidated" 
within the meaning of Treasury Regulation Section 1.704-
1(b)(2)(ii)(g), liquidating distributions shall be made, pursuant 
to this Agreement, in accordance with the Members' positive 
Capital Account balances, as required by Treasury Regulation 
Section 1.704-1(b)(2)(ii)(b)(2), by the end of the taxable year 
or, if later, within ninety (90) days after the date of such 
liquidation.  In determining any Member's Capital Account balance 
pursuant to this Section 9.7, any item of gain, loss, deduction, 
and credit that has not previously been allocated pursuant to 
Article V shall be so allocated.  

IX.8   Section 708 Termination.  Notwithstanding any other 
provision of this Article IX, in the event that the Company is 
liquidated within the meaning of Section 1.704-1(b)(2)(ii)(g) of 
the Treasury Regulations, but no Dissolution Event has occurred, 
the assets of the Company shall not be liquidated, the Company's 
liabilities shall not be paid or discharged, and the Company's 
affairs shall not be wound up.

IX.9   Continuation of the Company.  Unless required by 
applicable law, no sale, transfer, assignment or other 
disposition by either Member of all or any part of its Company 
Interest in accordance with the terms of this Agreement shall 
cause a dissolution of the Company, and, if such a dissolution is 
required under applicable law, immediately upon such sale, 
transfer, assignment or other disposition by either Member, the 
Company shall be reconstituted as a limited liability company, 
governed by this Agreement, among the transferee, purchaser or 
assignee and the remaining Member or Members; provided, however, 
that nothing in this Section 9.9 shall be construed to conflict 
with the requirement in Section 9.1(a) of this Agreement that a 
Bankruptcy of any Member shall cause the dissolution of the 
Company.  A Member's rights (i) under the Transaction Documents 
and (ii) to be a Member shall terminate upon a Transfer of that 
Member's Company Interest (including without limitation a 
Transfer pursuant to Sections 8.2, 8.3 or 9.1 of this Agreement).

IX.10   Waiver of Certain Rights.  Except as provided in this 
Agreement or as otherwise agreed in writing by the Members, to 
the extent permitted by Delaware law, each Member hereby waives 
(i) all rights it may have under Delaware law to cause the 
dissolution of the Company (other than dissolution by operation 
of law as a result of a transfer of its Company Interest as 
expressly permitted by this Agreement), (ii) to the extent a 
dissolution occurs by operation of law, the right to cause the 
Company to wind up its affairs and make distributions to the 
Members pursuant to Article IX upon the occurrence of such 
dissolution and (iii) all rights to partition with respect to 
real and personal property, provided that this clause shall not 
apply to assets that have previously been distributed by the 
Company to the Members.
