Right shall in any manner be construed to limit in any way the right of the
Company or an Affiliate to terminate a Key Employee's employment at any time,

would otherwise have under this Plan, or give any right to such a Key Employee
to remain employed by the Company or an Affiliate in any particular position or
at any particular rate of compensation.

            5.1 Grants of Options.

                  (a) Grant. The Committee may grant Incentive Stock Options
and/or Non-Statutory Options to Key Employees. Eligible Directors of the Company
may only be granted Non-Statutory Options. All Options under this Plan shall be
granted within ten years of the date on which this Plan is adopted or the date

under an Incentive Stock Option shall be not less than 100 percent of the Fair
Market Value per share of such Common Stock on the date the Option is granted.
The purchase price per share of Common Stock under each Non-Statutory Option
shall be determined by the Committee, but shall be not less than 90% of the Fair
Market Value per share of such Common Stock on the date such Non-Statutory
Option is granted; provided, however, that with respect to the Options initially
granted under this Plan in connection with the IPO, the purchase price per share
will be the IPO Price. The Option price may be subject to adjustment in
accordance with the provisions of Section 10.2 hereof.

                                      -5-
<PAGE>
                  (c) Option Agreements. Options and any Stock Appreciation
Rights attached to such Options shall be evidenced by Option Agreements in such
form and containing such terms and conditions as the Committee shall approve,
which terms and conditions need not be the same for all Options.

                  (d) Options Nontransferable. Options shall not be transferable
except in accordance with Section 5.1(d)(1) below or by will or the laws of
descent and distribution (or to a designated beneficiary in the event of an
optionee's death) or, in the case of a nonstatutory stock option, if permitted
in any specific case by the Committee in their sole discretion, pursuant to a
qualified domestic relations order as defined under the Code or Title I of
ERISA, or the rules thereunder. Except as provided above, Options will be
exercisable during the lifetime of an optionee only by such optionee or his or
her guardian or legal representative. Nothing contained herein shall be deemed
inconsistent with the provisions herein set forth pertaining to the exercise of
an option by the estate of a deceased holder.

                  (e) Transferability of Nonstatutory Stock Options.
Notwithstanding the foregoing, the Committee may provide that a Grantee may
transfer Nonstatutory Stock Options to family members, one or more trusts for
the benefit of family members, or one or more partnerships of which family
members are the only partners, according to such terms as the Committee may
determine; provided that the Grantee receives no consideration for the transfer
of an Option and the transferred Option shall continue to be subject to the same
terms and conditions as were applicable to the Option immediately before the
transfer.

                  (f) Substitution and Cancellation. The Committee, in its sole
discretion, may grant to a Key Employee or an Eligible Director who has been
granted an Option under this Plan, in exchange for the surrender and
cancellation of such Option, a new Option having a purchase price lower (or
higher) than the purchase price provided in the Option so surrendered and
canceled and containing such other terms as the Committee may deem appropriate,
subject to such limitations or restrictions with respect to Incentive Stock
Options as may be imposed by the Code.

            5.2 Exercise of Options.

                  (a) Term of Options; Vesting. The term of an Option and any
related Stock Appreciation Right granted under this Plan to a Key Employee shall
be ten (10) years from the date of grant. An Option shall become 100% vested at
the earliest of the following times if the optionee is an Employee at such time:
(i) the Employee's normal retirement date, (ii) the Employee's death or
Disability, (iii) five years from the date of grant or (iv) the occurrence of a
Change of Control. Each Option shall vest and become exercisable in cumulative
installments to the extent of 25% of the number of shares originally covered
thereby on and after the second, third, fourth and fifth anniversaries of the
grant of the Option, if the optionee is an Employee on such anniversary. In its
sole discretion, the Committee may prescribe shorter installments or accelerate
the exercisability of any Option at any time. In addition, any option granted to
an Eligible Director shall become 100% vested upon a Change of Control.

                                      -6-
<PAGE>
                  (b) Payment on Exercise. No shares of Common Stock shall be
issued on the exercise of an Option unless paid for in full at the time of
purchase. Payment for shares of Common Stock purchased upon the exercise of an
Option shall be made in cash or, with the consent of the Committee, in whole or
in part in such shares of Common Stock held for at least six months valued at
the then Fair Market Value thereof. Stock certificates for the shares of Common
Stock so paid will be issued and delivered to the person entitled thereto only
at the Company's office in Philadelphia, PA. No person shall have any rights as
a stockholder with respect to any share of Common Stock covered by an Option
unless and until such person shall have become the holder of record of such
share, and, except as otherwise permitted in Section 10.2 hereof, no adjustment
shall be made for dividends (ordinary or extraordinary, whether in cash,
securities or other property or distributions or other rights) in respect of
such share for which the record date is prior to the date on which such person
shall have become the holder of record thereof.

                  (c) Exercise upon Dissolution, Liquidation or Winding Up. If
at any time after an Option or Stock Appreciation Right has become exercisable
and prior to its exercise and expiration, a voluntary dissolution, liquidation
(other than a liquidation into another corporation which agrees to continue this
Plan) or winding up of the affairs of the Company shall be proposed, the Company
shall cause notice in writing to be mailed to each person holding an Option or
Stock Appreciation Right under this Plan, which notice shall be mailed not less
than twenty days prior to the closing of the transfer books of the Company or
the record date for determination of the holders of Common Stock of the Company
entitled to participate in such dissolution, liquidation or winding up, as the
case may be, to the end that during such notice period the holder of any Option
or Stock Appreciation Right, to the extent that the same is then exercisable by
such holder, may, subject to the terms of Article V hereof, either (i) purchase
Common Stock in accordance with the terms of the Option and be entitled, in
respect of the number of shares so purchased, with respect to such proposed
dissolution, liquidation or winding up of the affairs of the Company, or (ii)
exercise such Stock Appreciation Right(s) and be paid in cash, or to the extent
paid in shares of Common Stock, be entitled to all of the rights of other
holders of Common Stock with respect to such proposed dissolution, liquidation
or winding up of the affairs of the Company. Each Option and Stock Appreciation
Right at the time outstanding and all rights thereunder shall terminate at the
close of business on the twentieth day after mailing of such notice to the
holder of such Option or Stock Appreciation Right or on the record date for
determination of holders of Common Stock entitled to participate in such
dissolution, liquidation or winding up, whichever is later.

                  (d) Notice. If an optionee desires to exercise all of part of
such optionee's currently exercisable Options or Stock Appreciation Rights, such
optionee shall notify the Secretary of the Company, in writing or by telephone,
as designated in the Options or Stock Appreciation Rights which the optionee
wishes to exercise. The date of such notice shall be referred to herein as the
"Notice Date". Within three days after the Notice Date (the "Election Date"),
the Secretary of the Company will inform the optionee of the Committee's
determination regarding exercisability of the Options.

                  (e) Receipt. In the event that the optionee exercises Stock
Appreciation Rights, the optionee will receive an amount determined pursuant to
the provisions of Section 5.4

                                      -7-
<PAGE>
(less applicable withholding taxes) within five days of the Election Date. In
the event that an optionee exercises Options, the optionee shall comply with all
requirements set forth in the Option Agreement in connection with the purchase
of shares of Common Stock under this Plan.

            5.3 Incentive Stock Options.

                  (a) Annual Limitation. Any other provision of this Plan
notwithstanding, but subject to the limitation of Section 3.2 relating to the
aggregate number of shares subject to this Plan, the aggregate Fair Market Value
(determined as of the time the Option is granted) of the Common Stock with
respect to which Incentive Stock Options are exercisable for the first time by
any Employee during any calendar year (under this Plan and any other plans of
the Company and its Subsidiaries) shall not exceed $100,000. The limitation set
forth herein shall apply as and to the extent required to enable Incentive Stock
Options to qualify under Section 422 of the Code and, if such Section 422 is
amended, the Committee shall have the power to make corresponding changes in the
limitation set forth herein.

                  (b) Incentive Stock Options Granted to Ten Percent
Stockholders. No Incentive Stock Option shall be granted to any Key Employee who
owns, directly or indirectly pursuant to Section 424(d) of the Code, stock
possessing more than ten (10) percent of the total combined voting power of all
classes of stock of the Company or any Subsidiary, unless at the time such
Incentive Stock Option is granted, the price of the Incentive Stock Option is at
least 110 percent of the Fair Market Value of the Common Stock subject to the
Incentive Stock Option and such Incentive Stock Option, by its terms, is not
exercisable after the expiration of five (5) years from the date such Incentive
Stock Option is granted.

                  (c) Notice. Each Key Employee shall give prompt notice to the
Company of any disposition of shares acquired upon exercise of an Incentive
Stock Option if such disposition occurs within either two years after the date
of grant or one year after the date of transfer of such shares to the Key
Employee upon the exercise of such Incentive Stock Option.

                  (d) Consent. To the extent appropriate to avoid a
"modification" or other event described in Section 424(h) of the Code, a Key
Employee's rights under an Incentive Stock Option (including the rights to pay
the exercise price in Common Stock, to exercise a related Stock Appreciation
Right and to receive cash, shares, or a combination upon exercise of a related
Stock Appreciation Right) shall be set forth in the Option Agreement at the date
of grant, so as to preclude any requirement that further Committee consent be
given after the date of grant.

            5.4 Stock Appreciation Rights Attached to Options.

                  (a) Award. The Committee may award a Stock Appreciation Right
with respect to any shares of Common Stock covered by any Option granted under
this Plan to a Key Employee and such Stock Appreciation Right shall be granted
as of the time of the grant of the related Option.

                  (b) Terms and Conditions. Each Stock Appreciation Right shall
be subject to the same terms and conditions as the related Option with respect
to the date of

                                      -8-
<PAGE>
expiration, limitations on transferability and eligibility to exercise. A Stock
Appreciation Right granted in connection with an Incentive Stock Option may be
exercised only when the Fair Market Value of the shares of Common Stock subject
to such Incentive Stock Option exceeds the exercise price of such Incentive
Stock Option. No Stock Appreciation Right may be exercised after the related
Option becomes nonexercisable. Stock Appreciation Rights shall be payable, at
the election of the Committee, in the form of cash, Common Stock or a
combination thereof.

                  (c) Amount of Compensation. The amount of compensation which
shall be payable pursuant to the exercise of a Stock Appreciation Right shall be
equal to the excess of the Fair Market Value of one share of Common Stock on the
date the Secretary of the Company receives notice of the exercise of such Stock
Appreciation Right over the purchase price per share under the related Option as
determined under Section 5.1(b) hereof, multiplied by the number of Option
shares with respect to which the Stock Appreciation Right is exercised.

                  (d) Termination of Option. Upon the exercise of a Stock
Appreciation Right, the related Option shall cease to be exercisable as to the
number of shares of Common Stock with respect to which such Stock Appreciation
Right was exercised.

Employee of the Company or of another Affiliate.

            6.2 Death or Disability. If a Key Employee's employment is
terminated as a result of Disability or death, such Employee, or such Employee's
legal representatives in the event of death, shall be entitled to exercise the
Option or Stock Appreciation Right in whole or in part at any time within one
year following the Disability (defined in accordance with Section 422(c)(6) of
the Code in the case of an Incentive Stock Option) or death of such Key
Employee.

Eligible Director of the Company for any reason (except as a result of becoming
an Employee of the Company or an Affiliate or as a result of his retirement,
Disability or death), such non-employee director's Options shall terminate after
90 days. In the event of an Eligible Director's death or Disability, any
outstanding Options shall remain exercisable for one year from the date of death
or Disability, but in no event shall such period extend beyond the original term
of the Option.

                                   ARTICLE VII

                               Administration Plan

            7.1 The Committee. The Plan shall be administered and interpreted by
a committee of the Board (the "Committee"); provided, however, that grant
decisions made hereunder shall be made by at least two persons, each of whom may
be (i) "outside directors" as defined under Section 162(m) of the Internal
Revenue Code, and (ii) "non-employee directors" as defined under Rule 16b-3 of
the Securities Exchange Act of 1934 or any successor provisions and shall
satisfy the requirements of Section 12 hereof. The Board may appoint a
subcommittee for this purpose, in which case references herein to the
"Committee": shall mean the subcommittee as appropriate. A majority of the
Committee shall constitute a quorum thereof and the actions of a majority of the
Committee at a meeting at which a quorum is present, or actions unanimously
approved in writing by all members of the Committee, shall be the actions of the
Committee. Vacancies occurring on the Committee shall be filled by the Board.
The Committee shall have the full and final authority to interpret this Plan and
the agreements evidencing Options and Stock Appreciation Rights granted
hereunder (which agreements need not be identical), to prescribe, amend and
rescind rules and regulations, if any, relating to this Plan and to make all
determinations necessary or advisable for the administration of this Plan. The
Committee's determination in all matters referred to herein shall be conclusive
and binding for all purposes and upon all persons including, but without
limitation, the Company, the stockholders of the Company, the Committee and each
of the members thereof, and Employees of the Company, and their respective
successors in interest.

            7.2 Liability of Committee. No member of the Committee shall be
liable for anything done or omitted to be done by such member or by any other
member of the Committee in connection with this Plan, except for the willful
misconduct or gross negligence of such member. The Committee shall have the
power to engage outside consultants, auditors or other professional help to
assist in the fulfillment of the Committee's duties under this Plan at the
Company's expense.

            7.3 Determinations of the Committee. In making its determinations
concerning the Key Employees who shall receive Options and Stock Appreciation
Rights, as well as the number of shares to be covered thereby and time or times
at which they shall be granted, the Committee shall take into account the nature
of the services rendered by the respective Key

                                      -10-
<PAGE>
Employees, their past, present and potential contribution to the Company's
success and such other factors as the Committee may deem relevant. The Committee
shall also determine the form of Option Agreements to be issued under this Plan
and the terms and conditions to be included therein, provided such terms and
conditions are not inconsistent with the terms of this Plan. The Committee may,
in its discretion or in accordance with a direction from the Board, waive any
provisions of any Option Agreement, provided such waiver is not inconsistent
with the terms of this Plan as then in effect.

                                  ARTICLE VIII

                        Amendment and Termination of Plan

            8.1 Amendment of Plan.

                  (a) Generally. This Plan may be amended at any time and from
time to time by the Board of Directors of the Company but no amendment which (1)
decreases the minimum Option price provided in this Plan, (2) extends the period
during which Options and Stock Appreciation Rights may be granted under this
Plan, or (3) changes the class of Key Employees eligible to receive Options and
Stock Appreciation Rights shall be effective unless and until the same is
approved by the affirmative vote, in person or proxy, of the holders of a
majority of the shares of Common Stock of the Company present and entitled to
vote at a meeting held to take such action at which a quorum is present. No
termination or amendment of this Plan, without the consent of the holder of any
Option or Stock Appreciation Right then existing, may terminate such holder's
Option or Stock Appreciation Right or materially and adversely affect such
holder's rights thereunder.

                  (b) Amendments Relating to Incentive Stock Options. To the
extent applicable, this Plan is intended to permit the issuance of Incentive
Stock Options in accordance with the provisions of Section 422 of the Code. The
Plan may be modified or amended at any time, both prospectively and
retroactively, and in such manner as to affect Incentive Stock Options
previously granted (after taking account of Section 424(h) of the Code, relating
to "modifications", etc.), if such amendment or modification is necessary for
this Plan and the Incentive Stock Options granted hereunder to qualify under
said provisions of the Code.

            8.2 Termination. The Board may at any time terminate this Plan as of
any date specified in a resolution adopted by the Board. If not earlier
terminated, this Plan shall terminate on the tenth anniversary of the effective
date of the Plan. No Options or Stock Appreciation Rights may be granted after
this Plan has terminated. After this Plan shall terminate, the function of the
Committee will be limited to supervising the administration of Options and Stock
Appreciation Rights previously granted.

                                   ARTICLE IX

                             Exchange Act Compliance

                                      -11-
<PAGE>
            9.1 Additional Restrictions Under Rule 16b-3. Unless an optionee
could otherwise transfer option shares issued hereunder without incurring
liability under Section 16(b) of the Exchange Act, at least six months must
elapse from the date of acquisition of an Option to the date of disposition of
the shares issued upon exercise of the Option.

            9.2 Compliance with Rule 16b-3. It is the intent of the Company that
this Plan comply in all respects with applicable provisions of Rule 16b-3 under
the Exchange Act in connection with any grant of Options to or other transaction
by an optionee who is subject to Section 16 of the Exchange Act. Accordingly, if
any provision of this Plan or any agreement relating to an Option does not
comply with the requirements of Rule 16b-3 as then applicable to any such
optionee, such provision will be construed or deemed amended to the extent
necessary to conform to such requirements with respect to such person. In
addition, the Committee shall have no authority to make any amendment,
alteration, suspension, discontinuation, or termination of the Plan or any
agreement hereunder or take other action if such authority would cause an
optionee's transactions under the Plan not to be exempt under Rule 16b-3 under
the Exchange Act.

                                    ARTICLE X

                            Miscellaneous Provisions

            10.1 Restrictions Upon Resale of Unregistered Stock. If the shares
of Common Stock that have been transferred to a Key Employee or Eligible
Director pursuant to the terms of this Plan are not registered under the 1933
Act, pursuant to an effective registration statement, such Key Employee or
Eligible Director, if the Committee shall deem it advisable, may be required to
represent and agree in writing (i) that any shares of Common Stock acquired by
such Key Employee or Eligible Director pursuant to this Plan will not be sold
except pursuant to an effective registration statement under the 1933 Act, or
pursuant to an exemption from registration under the 1933 Act and (ii) that such
Key Employee or Eligible Director is acquiring such shares of Common Stock for
his or her own account and not with a view to the distribution thereof.

            10.2 Adjustment. In the event of any change (through
recapitalization, merger, consolidation, stock dividend, split up, combination
or exchange of shares or otherwise) in the character or amount of the Company
capital stock (or any other transaction described in Section 424(a) of the Code)
after any Option or Stock Appreciation Right is granted hereunder and prior to
the exercise thereof, (i) the Option, to the extent that it has not been
exercised, shall entitle the holder to such number and kind of securities as
such holder would have been entitled to had such holder actually owned the stock
subject to the Option at the time of the occurrence of such change and (ii) any
outstanding Stock Appreciation Rights shall be similarly adjusted. If any other
event shall occur, prior to the exercise of an Option granted hereunder, which
shall increase or decrease the amount of capital stock outstanding and which the
Committee, in its sole discretion, shall determine equitably requires an
adjustment in the number of shares which the holder should be permitted to
acquire or the number of Stock Appreciation Rights such holder should be
entitled to exercise, such adjustment as the Committee shall determine may be
made, and when so made shall be effective and binding for all purposes of this
Plan.

                                      -12-
<PAGE>
            10.3 Withholding of Taxes. Each Key Employee who exercises an Option
to purchase Common Stock or Stock Appreciation Rights shall agree to pay to the
Company, or make arrangements satisfactory to the Committee regarding payment
of, any taxes of any kind required by law to be withheld with respect to the
transfer to such Employee of such shares of Common Stock.

            10.4 Use of Proceeds. The proceeds from the sale of Common Stock
pursuant to Options granted under this Plan shall constitute general funds of
the Company and may be used for such corporate purposes as the Company may
determine.

            10.5 Other Grants. Options and Stock Appreciation Rights may be
granted under this Plan from time to time in substitution for stock options
and/or stock appreciation rights held by employees of other corporations who are
or are about to become employees of the Company as the result of a merger or
consolidation of the employing corporation with the Company, or the acquisition
by the Company of the assets of the employing corporation, or the acquisition by
the Company of stock of the employing corporation as the result of which it
becomes an Affiliate of the Company. Further, Stock Appreciation Rights may be
granted under the Plan from time to time in connection with stock options
assumed by the Company as part of any such merger, consolidation or acquisition.
The terms and conditions of the substituted Options or related Stock
Appreciation Rights so granted may vary from the terms and conditions set forth
herein to such extent as the Committee may deem appropriate to conform, in whole
or in part, to the provisions of the substituted stock incentives.

            10.6 Other Benefits. Nothing contained herein shall prevent the
Company from establishing other incentive plans in which Key Employees and
Eligible Directors in the Plan may also participate. No award under this Plan
shall be considered as compensation in calculating any insurance, pension or
other benefit for which the recipient is eligible unless any such insurance,
pension or other benefit is granted under a plan which expressly provides that
compensation under this Plan (and specifying the type of such compensation)
shall be considered as compensation under such plan.

                                CREDIT AGREEMENT

      THIS CREDIT AGREEMENT, dated as of the 8th day of February, 2002 (this
"Agreement"), is made between RADIAN GROUP INC., a Delaware corporation with its
principal offices in Philadelphia, Pennsylvania (the "Borrower"), and FIRST
UNION NATIONAL BANK ("First Union" or "Lender").

                                    RECITALS

      A. The Borrower has requested that the Lender make available to the
Borrower a revolving credit facility in the aggregate principal amount of
$50,000,000. The Borrower will use the proceeds of this facility to provide for
the working capital and general corporate requirements of the Borrower and its
subsidiaries, to pay certain transaction fees and expenses in connection
herewith and to finance permitted acquisitions by the Borrower or any of its
subsidiaries.

      B. The Lender is willing to make available to the Borrower the credit
facility described herein subject to and on the terms and conditions set forth
in this Agreement.

                                    AGREEMENT

      NOW, THEREFORE, in consideration of the mutual provisions, covenants and
agreements herein contained, the parties hereto hereby agree as follows:

                                    ARTICLE I

                                   DEFINITIONS

      1.1 Defined Terms. For purposes of this Agreement, in addition to the
terms defined elsewhere herein, the following terms shall have the meanings set
forth below (such meanings to be equally applicable to the singular and plural
forms thereof):

      "Account Designation Letter" shall mean a letter from the Borrower to the
Lender, duly completed and signed by an Authorized Officer and in form and
substance satisfactory to the Lender, listing any one or more accounts to which
the Borrower may from time to time request the Lender to forward the proceeds of
any Loans made hereunder.

      "Acquisition" shall mean any transaction or series of related
transactions, consummated on or after the date hereof, by which the Borrower
directly, or indirectly through one or more Subsidiaries, (i) acquires any going
business, or all or substantially all of the assets, of any Person, whether
through purchase of assets, merger or otherwise, or (ii) acquires securities or
other ownership interests of any Person having at least a majority of combined
voting power of the then outstanding securities or other ownership interests of
such Person.

      "Adjusted LIBOR Rate" shall mean, at any time with respect to any Loan, a
rate per annum equal to the LIBOR Rate as in effect at such time plus the
Applicable Margin Percentage.

      "Affiliate" shall mean, as to any Person, each other Person that directly,

special circumstances) having the right to vote in the election of directors or
other governing body of such Person. Notwithstanding the foregoing, (x) no
individual shall be an "Affiliate" of any Person or of any of its Subsidiaries
solely by reason of such individual being a director, officer or employee of
such Person or any of its Subsidiaries; and (y) the Lender shall not be an
Affiliate of the Borrower or any of its Subsidiaries.

      "Agreement" shall mean this Credit Agreement, as amended, modified or
supplemented from time to time.

                          AMOUNT AND TERMS OF THE LOANS

      2.1 Commitment. The Lender agrees, subject to and on the terms and
conditions of this Agreement, to make loans (each, a "Loan," and collectively,
the "Loans") to the Borrower, from time to time on any Business Day during the
period from and including the Closing Date to but not including the Termination
Date, in an aggregate principal amount at any time outstanding not greater than
its Commitment at such time, provided that no Borrowing shall be made if,
immediately after giving effect thereto, the aggregate principal amount of Loans
outstanding at such time would exceed the Commitment at such time. Subject to
and on the terms and conditions of this Agreement, the Borrower may borrow,
repay and reborrow Loans.

      2.2 Borrowings.

      (a) The Loans shall, at the option of the Borrower and subject to the
terms and conditions of this Agreement, be either (i) Base Rate Loans or (ii)
LIBOR Loans (each, a "Type" of Loan), provided that (x) all Loans comprising the
same Borrowing shall, unless otherwise

                                       14
<PAGE>
specifically provided herein, be of the same Type, and (y) no Borrowing of LIBOR
Loans may be made at any time prior to the third (3rd) Business Day after the
Closing Date.

      (b) In order to make a Borrowing (other than Borrowings involving
continuations or conversions of outstanding Loans, which shall be made pursuant
to SECTION 2.11), the Borrower will give the Lender written notice not later
than 11:00 a.m., Charlotte time, three (3) Business Days prior to each Borrowing
to be comprised of LIBOR Loans and not later than one (1) Business Day prior to
each Borrowing to be comprised of Base Rate Loans; provided, however, that the
request for the Borrowing of the Loan to be made on the Closing Date may, at the
discretion of the Lender, be given later than the times specified hereinabove.
Each such notice (each, a "Notice of Borrowing") shall be irrevocable, shall be
given in the form of EXHIBIT B-1 and shall specify (1) the aggregate principal
amount and initial Type of the Loans to be made pursuant to such Borrowing, (2)
in the case of a Borrowing of LIBOR Loans, the initial Interest Period to be
applicable thereto, and (3) the requested date of such Borrowing (the "Borrowing
Date"), which shall be a Business Day. Notwithstanding anything to the contrary
contained herein:

            (i) the aggregate principal amount of each Borrowing comprised of
      Base Rate Loans shall not be less than $3,000,000 or, if greater, an
      integral multiple of $1,000,000 in excess thereof (or, if less, in the
      amount of the aggregate Unutilized Commitments), and the aggregate
      principal amount of each Borrowing comprised of LIBOR Loans shall not be
      less than $3,000,000 or, if greater, an integral multiple of $1,000,000 in
      excess thereof;

            (ii) if the Borrower shall have failed to designate the Type of
      Loans comprising a Borrowing, the Borrower shall be deemed to have
      requested a Borrowing comprised of Base Rate Loans; and

            (iii) if the Borrower shall have failed to select the duration of
      the Interest Period to be applicable to any Borrowing of LIBOR Loans, then
      the Borrower shall be deemed to have selected an Interest Period with a
      duration of one month;

      (c) Not later than 1:00 p.m., Charlotte time, on the requested Borrowing
Date, the Lender will make such amounts available to the Borrower.

      2.3 Disbursements.

      (a) The Borrower hereby authorizes the Lender to disburse the proceeds of
each Borrowing in accordance with the terms of any written instructions from any
of the Authorized Officers, provided that the Lender shall not be obligated
under any circumstances to forward amounts to any account not listed in an
Account Designation Letter. The Borrower may at any time deliver to the Lender
an Account Designation Letter listing any additional accounts or deleting any
accounts listed in a previous Account Designation Letter.

      (b) The Lender may, at its option, make and maintain any Loan at, to or
for the account of any of its Lending Offices, provided that any exercise of
such option shall not affect the obligation of the Borrower to repay such Loan
to or for the account of the Lender in accordance with the terms of this
Agreement.

                                       15

      2.4 Note.

      (a) The Loans shall be evidenced by a Note appropriately completed
substantially in the form of EXHIBIT A by the Borrower.

      (b) The Note shall (i) be executed by the Borrower, (ii) be payable to the
order of the Lender, (iii) be dated as of the Closing Date, (iv) be in a stated
principal amount equal to the Commitment, (v) bear interest in accordance with
the provisions of SECTION 2.8, as the same may be applicable from time to time
to the Loans made by the Lender, and (vi) be entitled to all of the benefits of
this Agreement and the other Credit Documents and subject to the provisions
hereof and thereof.

      (c) The Lender will record on its internal records the amount and Type of
each Loan made by it and each payment received by it in respect thereof and
will, in the event of any transfer of its Note, either endorse on the reverse
side thereof or on a schedule attached thereto (or any continuation thereof) the
outstanding principal amount and Type of the Loans evidenced thereby as of the
date of transfer; provided, however, that the failure of the Lender to make any
such recordation or provide any such information, or any error therein, shall
not affect the Borrower's obligations under this Agreement or the Note.

      2.5 Termination of Commitment.

      (a) The Commitment shall be automatically and permanently terminated on
the Termination Date.

      (b) At any time and from time to time after the date hereof, upon not less
than five (5) Business Days' prior written notice to the Agent, the Borrower may
terminate in whole or reduce in part the aggregate Unutilized Commitments,
provided that any such partial reduction shall be in an aggregate amount of not
less than $5,000,000 or, if greater, an integral multiple of $1,000,000 in
excess thereof. The amount of any termination or reduction made under this
subsection (b) may not thereafter be reinstated.

      2.6 Mandatory Payments and Prepayments.

      (a) Except to the extent due or paid sooner pursuant to the provisions of
this Agreement, the aggregate outstanding principal of the Loans shall be due
and payable in full on the Maturity Date.

      (b) In the event that, at any time, the aggregate principal amount of
Loans outstanding at such time shall exceed the Commitment at such time (after
giving effect to any concurrent termination or reduction thereof), the Borrower
will immediately prepay the outstanding principal amount of the Loans in the
amount of such excess.

      (c) Each payment or prepayment of a LIBOR Loan made pursuant to the
provisions of this Section on a day other than the last day of the Interest
Period applicable thereto shall be made together with all amounts required under
SECTION 2.17 to be paid as a consequence thereof.

                                       16
<PAGE>
      2.7 Voluntary Prepayments. At any time and from time to time, the Borrower
shall have the right to prepay the Loans, in whole or in part, without premium
or penalty (except as provided in clause (iii) below), upon written notice given
to the Lender not later than 11:00 a.m., Charlotte time, three (3) Business Days
prior to each intended prepayment of LIBOR Loans and one (1) Business Day prior
to each intended prepayment of Base Rate Loans, provided that (i) each partial
prepayment shall be in an aggregate principal amount of not less than $3,000,000
or, if greater, an integral multiple of $1,000,000 in excess thereof, (ii) no
partial prepayment of a LIBOR Loan made pursuant to any single Borrowing shall
reduce the outstanding principal amount of the remaining LIBOR Loan under such
Borrowing to less than $3,000,000 or to any greater amount not an integral
multiple of $1,000,000 in excess thereof, and (iii) unless made together with
all amounts required under SECTION 2.17 to be paid as a consequence of such
prepayment, a prepayment of a LIBOR Loan may be made only on the last day of the
Interest Period applicable thereto. Each such notice shall specify the proposed
date of such prepayment and the aggregate principal amount and Type of the Loans
to be prepaid (and, in the case of LIBOR Loans, the Interest Period of the
Borrowing pursuant to which made), and shall be irrevocable and shall bind the
Borrower to make such prepayment on the terms specified therein. Loans prepaid
pursuant to this Section may be reborrowed, subject to the terms and conditions
of this Agreement.

      2.8 Interest.

      (a) The Borrower will pay interest in respect of the unpaid principal
amount of each Loan, from the date of Borrowing thereof until such principal
amount shall be paid in full, (i) at the Base Rate, as in effect from time to
time during such periods as such Loan is a Base Rate Loan, and (ii) at the
Adjusted LIBOR Rate, as in effect from time to time during such periods as such
Loan is a LIBOR Loan.

      (b) Upon the occurrence and during the continuance of any default by the
Borrower in the payment of any principal of or interest on any Loan, any fees or
other amount hereunder when due (whether at maturity, pursuant to acceleration
or otherwise), and upon the occurrence and during the continuance of any other
Event of Default, all outstanding principal amounts of the Loans and, to the
greatest extent permitted by law, all interest accrued on the Loans and all
other accrued and outstanding fees and other amounts hereunder, shall, at the
option of the Lender, bear interest at a rate per annum equal to the interest
applicable from time to time thereafter to such Loans (whether the Base Rate or
Adjusted LIBOR Rate) plus 2% (or, in the case of fees and other amounts, at the
Base Rate plus 2%) and, in each case, such default interest shall be payable on
demand. To the greatest extent permitted by law, interest shall continue to
accrue after the filing by or against the Borrower of any petition seeking any
relief in bankruptcy or under any law pertaining to insolvency or debtor relief.

      (c) Accrued (and theretofore unpaid) interest shall be payable as follows:

            (i) in respect of each Base Rate Loan (including any Base Rate Loan
      or portion thereof paid or prepaid pursuant to the provisions of SECTION
      2.6, except as provided hereinbelow), in arrears on the last Business Day
      of each calendar quarter, beginning with the first such day to occur after
      the Closing Date; provided, that in the event the Loans are repaid or
      prepaid in full and the Commitment has been terminated,

                                       17
<PAGE>
      then accrued interest in respect of all Base Rate Loans shall be payable
      together with such repayment or prepayment on the date thereof;

            (ii) in respect of each LIBOR Loan (including any LIBOR Loan or
      portion thereof paid or prepaid pursuant to the provisions of SECTION 2.6,
      except as provided hereinbelow), in arrears (y) on the last Business Day
      of the Interest Period applicable thereto (subject to the provisions of
      clause (iv) in SECTION 2.10) and (z) in addition, in the case of a LIBOR
      Loan with an Interest Period having a duration of six months or longer, on
      each date on which interest would have been payable under clause (y) above
      had successive Interest Periods of three months' duration been applicable
      to such LIBOR Loan; provided, that in the event all of the LIBOR Loan made
      pursuant to a single Borrowing is repaid or prepaid in full, then accrued
      interest in respect of such LIBOR Loan shall be payable together with such
      repayment or prepayment on the date thereof; and

            (iii) in respect of any Loan, at maturity (whether pursuant to
      acceleration or otherwise) and, after maturity, on demand.

      (d) Nothing contained in this Agreement or in any other Credit Document
shall be deemed to establish or require the payment of interest to the Lender at
a rate in excess of the maximum rate permitted by applicable law. If the amount
of interest payable for the account of the Lender on any interest payment date
would exceed the maximum amount permitted by applicable law to be charged by the
Lender, the amount of interest payable for its account on such interest payment
date shall be automatically reduced to such maximum permissible amount. In the
event of any such reduction affecting the Lender, if from time to time
thereafter the amount of interest payable for the account of the Lender on any
interest payment date would be less than the maximum amount permitted by
applicable law to be charged by the Lender, then the amount of interest payable
for its account on such subsequent interest payment date shall be automatically
increased to such maximum permissible amount, provided that at no time shall the
aggregate amount by which interest paid for the account of the Lender has been
increased pursuant to this sentence exceed the aggregate amount by which
interest paid for its account has theretofore been reduced pursuant to the
previous sentence.

      (e) The Lender shall promptly notify the Borrower upon determining the
interest rate for each Borrowing of LIBOR Loans after its receipt of the
relevant Notice of Borrowing or Notice of Conversion/Continuation, and upon each
change in the Base Rate; provided, however, that the failure of the Lender to
provide the Borrower with any such notice shall not affect any obligations of
the Borrower nor result in any liability on the part of the Lender to the
Borrower. Each such determination (including each determination of the Reserve
Requirement) shall, absent manifest error, be conclusive and binding on all
parties hereto.

      2.9 Fees. The Borrower agrees to pay to the Lender:

      (a) on the date of execution of this Agreement, the fees described in
paragraph (2) of the Fee Letter; and

                                       18
<PAGE>
      (b) a commitment fee for each calendar quarter (or portion thereof) for
the period from the date of this Agreement to the Termination Date, at a per
annum rate equal to the Applicable Margin Percentage in effect for such fee from
time to time during such quarter on the Unutilized Commitment, calculated on the
basis of a 360-day year for the actual days elapsed commencing on the execution
date of this Agreement, payable in arrears (i) on the last Business Day of each
calendar quarter, beginning with the first such day to occur after the Closing
Date, and (ii) on the Termination Date.

      2.10 Interest Periods. Concurrently with the giving of a Notice of
Borrowing or Notice of Conversion/Continuation in respect of any Borrowing
comprised of Base Rate Loans to be converted into, or LIBOR Loans to be
continued as, LIBOR Loans, the Borrower shall have the right to elect, pursuant
to such notice, the interest period (each, an "Interest Period") to be
applicable to such LIBOR Loans, which Interest Period shall, at the option of
the applicable Borrower be a one, two, three or six-month period; provided,
however, that:

            (i) all LIBOR Loans comprising a single Borrowing shall at all times
      have the same Interest Period;

            (ii) the initial Interest Period for any LIBOR Loan shall commence
      on the date of the Borrowing of such LIBOR Loan (including the date of any
      continuation of, or conversion into, such LIBOR Loan), and each successive
      Interest Period applicable to such LIBOR Loan shall commence on the day on
      which the next preceding Interest Period applicable thereto expires;

            (iii) LIBOR Loans may not be outstanding under more than four (4)
      separate Interest Periods at any one time (for which purpose Interest
      Periods shall be deemed to be separate even if they are coterminous);

            (iv) if any Interest Period otherwise would expire on a day that is
      not a Business Day, such Interest Period shall expire on the next
      succeeding Business Day unless such next succeeding Business Day falls in
      another calendar month, in which case such Interest Period shall expire on
      the next preceding Business Day;

            (v) the Borrower may not select any Interest Period that begins
      prior to the Closing Date or that expires after the Maturity Date;

            (vi) if any Interest Period begins on a day for which there is no
      numerically corresponding day in the calendar month during which such
      Interest Period would otherwise expire, such Interest Period shall expire
      on the last Business Day of such calendar month; and

            (vii) if, upon the expiration of any Interest Period applicable to a
      Borrowing of LIBOR Loans, the applicable Borrower shall have failed to
      elect a new Interest Period to be applicable to such LIBOR Loans, then the
      Borrower shall be deemed to have elected to convert such LIBOR Loans into
      Base Rate Loans as of the expiration of the then current Interest Period
      applicable thereto.

                                       19

      (a) The Borrower shall have the right, on any Business Day occurring on or
after the Closing Date, to elect (i) to convert all or a portion of the
outstanding principal amount of any Base Rate Loans into LIBOR Loans, or to
convert any LIBOR Loans the Interest Periods for which end on the same day into
Base Rate Loans, or (ii) upon the expiration of any Interest Period, to continue
all or a portion of the outstanding principal amount of any LIBOR Loans the
Interest Periods for which end on the same day for an additional Interest
Period, provided that (x) any such conversion of LIBOR Loans into Base Rate
Loans shall involve an aggregate principal amount of not less than $3,000,000
or, if greater, an integral multiple of $1,000,000 in excess thereof; any such
conversion of Base Rate Loans into, or continuation of, LIBOR Loans shall
involve an aggregate principal amount of not less than $3,000,000 or, if
greater, an integral multiple of $1,000,000 in excess thereof; and no partial
conversion of LIBOR Loans made pursuant to a single Borrowing shall reduce the
outstanding principal amount of such LIBOR Loans to less than $3,000,000 or to
any greater amount not an integral multiple of $1,000,000 in excess thereof, (y)
except as otherwise provided in SECTION 2.15(D), LIBOR Loans may be converted
into Base Rate Loans only on the last day of the Interest Period applicable
thereto (and, in any event, if a LIBOR Loan is converted into a Base Rate Loan
on any day other than the last day of the Interest Period applicable thereto,
the Borrower will pay, upon such conversion, all amounts required under SECTION
2.17 to be paid as a consequence thereof), and (z) no conversion of Base Rate
Loans into LIBOR Loans or continuation of LIBOR Loans shall be permitted during
the continuance of a Default or Event of Default.

      (b) The Borrower shall make each such election by giving the Lender
written notice not later than 11:00 a.m., Charlotte time, three (3) Business
Days prior to the intended effective date of any conversion of Base Rate Loans
into, or continuation of, LIBOR Loans and one (1) Business Day prior to the
intended effective date of any conversion of LIBOR Loans into Base Rate Loans.
Each such notice (each, a "Notice of Conversion/Continuation") shall be
irrevocable, shall be given in the form of EXHIBIT B-2 and shall specify (x) the
date of such conversion or continuation (which shall be a Business Day), (y) in
the case of a conversion into, or a continuation of, LIBOR Loans, the Interest
Period to be applicable thereto, and (z) the aggregate amount and Type of the
Loans being converted or continued. In the event that the Borrower shall fail to
deliver a Notice of Conversion/Continuation as provided herein with respect to
any outstanding LIBOR Loans, such LIBOR Loans shall automatically be converted
to Base Rate Loans upon the expiration of the then current Interest Period
applicable thereto (unless repaid pursuant to the terms hereof). In the event
the Borrower shall have failed to select in a Notice of Conversion/Continuation
the duration of the Interest Period to be applicable to any conversion into, or
continuation of, LIBOR Loans, then the Borrower shall be deemed to have selected
an Interest Period with a duration of one month.

      2.12 Method of Payments; Computations.

      (a) All payments by the Borrower hereunder shall be made without setoff,
counterclaim or other defense, in Dollars and in immediately available funds to
the Lender, prior to 1:00 p.m., Charlotte time, on the date payment is due. Any
payment made as required hereinabove, but after 1:00 p.m., Charlotte time, shall
be deemed to have been made on the next succeeding Business Day. If any payment
falls due on a day that is not a Business Day, then

                                       20
<PAGE>
such due date shall be extended to the next succeeding Business Day (except that
in the case of LIBOR Loans to which the provisions of clause (iv) in SECTION
2.10 are applicable, such due date shall be the next preceding Business Day),
and such extension of time shall then be included in the computation of payment
of interest, fees or other applicable amounts.

      (b) The Lender may, but shall not be obligated to, debit the amount of any
such payment not made as and when required hereunder to any ordinary deposit
account of the Borrower with the Lender (with prompt notice to such Borrower);
provided, however, that the failure to give such notice shall not affect the
validity of such debit by the Lender.

      (c) All computations of interest and fees hereunder (including
computations of the Reserve Requirement) shall be made on the basis of a year
consisting of (i) in the case of interest on Base Rate Loans, 365/366 days, as
the case may be, and (ii) in all other instances, 360 days and in each case
under (i) and (ii) above, with regard to the actual number of days (including
the first day, but excluding the last day) elapsed.

      2.13 Recovery of Payments. The Borrower agrees that to the extent it makes
a payment or payments to or for the account of the Lender, which payment or
payments or any part thereof are subsequently invalidated, declared to be
fraudulent or preferential, set aside or required to be repaid to a trustee,
receiver or any other party under any bankruptcy, insolvency or similar state or
federal law, common law or equitable cause, then, to the extent of such payment
or repayment, the Obligation intended to be satisfied shall be revived and
continued in full force and effect as if such payment had not been received.

      2.14 Use of Proceeds. The proceeds of the Loans shall be used (i) to
provide for the working capital and general corporate requirements of the
Borrower and its Subsidiaries; (ii) to pay certain transaction fees and expenses
in connection with the Credit Documents in amounts acceptable to the Lender; and
(iii) to finance Permitted Acquisitions by the Borrower or any of its
Subsidiaries.

      2.15 Increased Costs; Change in Circumstances; Illegality; etc.

      (a) If, at any time after the date hereof and from time to time, the
introduction of or any change in any applicable law, rule or regulation or in
the interpretation or administration thereof by any Governmental Authority
charged with the interpretation or administration thereof, or compliance by the
Lender with any guideline or request from any such Governmental Authority
(whether or not having the force of law) given or made after the date hereof,
shall (i) subject the Lender to any tax or other charge, or change the basis of
taxation of payments to the Lender, in respect of any of its LIBOR Loans or any
other amounts payable hereunder or its obligation to make, fund or maintain any
LIBOR Loans (other than any change in the rate or basis of tax on the overall
net income of the Lender), (ii) impose, modify or deem applicable any reserve,
special deposit or similar requirement (but excluding any reserves to the extent
actually included within the Reserve Requirement in the calculation of the LIBOR
Rate) against assets of, deposits with or for the account of, or credit extended
by, the Lender, or (iii) impose on the Lender or its applicable Lending Office
any other condition, and the result of any of the foregoing shall be to increase
the cost to the Lender of making or maintaining any LIBOR Loans or to reduce the
amount of any sum received or receivable by the Lender hereunder, the

                                       21
<PAGE>
Borrower will, promptly upon demand therefor by the Lender, pay to the Lender
such additional amounts as shall compensate the Lender for such increase in
costs or reduction in return.

      (b) If, at any time after the date hereof and from time to time, the
Lender shall have reasonably determined that the introduction of or any change
in any applicable law, rule or regulation regarding capital adequacy or in the
interpretation or administration thereof by any Governmental Authority charged
with the interpretation or administration thereof, or compliance by the Lender
with any guideline or request from any such Governmental Authority (whether or
not having the force of law) given or made after the date hereof, has or would
have the effect, as a consequence of the Lender's Commitment or Loans, of
reducing the rate of return on the capital of the Lender or any Person
controlling the Lender to a level below that which the Lender or controlling
Person could have achieved but for such introduction, change or compliance
(taking into account the Lender's or controlling Person's policies with respect
to capital adequacy), the Borrower will, promptly upon demand therefor by the
Lender therefor, pay to the Lender such additional amounts as will compensate
the Lender or controlling Person for such reduction in return.

      (c) If, on or prior to the first day of any Interest Period, (y) the
Lender shall have determined that adequate and reasonable means do not exist for
ascertaining the applicable LIBOR Rate for such Interest Period or (z) the
Lender shall have determined that the rate of interest referred to in the
definition of "LIBOR Rate" upon the basis of which the Adjusted LIBOR Rate for
LIBOR Loans for such Interest Period is to be determined will not adequately and
fairly reflect the cost to the Lender of making or maintaining LIBOR Loans
during such Interest Period, the Lender will forthwith so notify the applicable
Borrower. Upon such notice, (i) all then outstanding LIBOR Loans shall
automatically, on the expiration date of the respective Interest Periods
applicable thereto (unless then repaid in full), be converted into Base Rate
Loans, (ii) the obligation of the Lender to make, to convert Base Rate Loans
into, or to continue, LIBOR Loans shall be suspended (including pursuant to the
Borrowing to which such Interest Period applies), and (iii) any Notice of
Borrowing or Notice of Conversion/Continuation given at any time thereafter with
respect to LIBOR Loans shall be deemed to be a request for Base Rate Loans, in
each case until the Lender shall have determined that the circumstances giving
rise to such suspension no longer exist and the Lender shall have so notified
the applicable Borrower.

      (d) Notwithstanding any other provision in this Agreement, if, at any time
after the date hereof and from time to time, the Lender shall have determined in
good faith that the introduction of or any change in any applicable law, rule or
regulation or in the interpretation or administration thereof by any
Governmental Authority charged with the interpretation or administration
thereof, or compliance with any guideline or request from any such Governmental
Authority (whether or not having the force of law), has or would have the effect
of making it unlawful for the Lender to make or to continue to make or maintain
LIBOR Loans, the Lender will forthwith so notify the applicable Borrower. Upon
such notice, (i) each of the Lender's then outstanding LIBOR Loans shall
automatically, on the expiration date of the respective Interest Period
applicable thereto (or, to the extent any such LIBOR Loan may not lawfully be
maintained as a LIBOR Loan until such expiration date, upon such notice), be
converted into a Base Rate Loan, (ii) the obligation of the Lender to make, to
convert Base Rate Loans into, or to continue, LIBOR Loans shall be suspended
(including pursuant to any Borrowing for which the Lender has received a Notice
of Borrowing but for which the Borrowing Date has not arrived),

                                       22
<PAGE>
and (iii) any Notice of Borrowing or Notice of Conversion/Continuation given at
any time thereafter with respect to LIBOR Loans shall, as to the Lender, be
deemed to be a request for a Base Rate Loan, in each case until the Lender shall
have determined that the circumstances giving rise to such suspension no longer
exist and shall have so notified the applicable Borrower.

      (e) Determinations by the Lender for purposes of this Section of any
increased costs, reduction in return, market contingencies, illegality or any
other matter shall, absent manifest error, be conclusive, provided that such
determinations are made in good faith. No failure by the Lender at any time to
demand payment of any amounts payable under this Section shall constitute a
waiver of its right to demand payment of any additional amounts arising at any
subsequent time. Nothing in this Section shall require or be construed to
require the Borrower to pay any interest, fees, costs or other amounts in excess
of that permitted by applicable law.

      2.16 Taxes.

      (a) Any and all payments by the Borrower hereunder or under any Note shall
be made, in accordance with the terms hereof and thereof, free and clear of and
without deduction for any and all present or future taxes, levies, imposts,
deductions, charges or withholdings, and all liabilities with respect thereto,
other than net income and franchise taxes imposed on the Lender by the United
States or any political subdivision or taxing authority thereof (all such
nonexcluded taxes, levies, imposts, deductions, charges, withholdings and
liabilities being hereinafter referred to as "Taxes"). If the Borrower shall be
required by law to deduct any Taxes from or in respect of any sum payable
hereunder or under the Note to the Lender, (i) the sum payable shall be
increased as may be necessary so that after making all required deductions
(including deductions applicable to additional sums payable under this Section),
the Lender receives an amount equal to the sum it would have received had no
such deductions been made, (ii) the Borrower will make such deductions, (iii)
the Borrower will pay the full amount deducted to the relevant taxation
authority or other authority in accordance with applicable law and (iv) the
Borrower will deliver to the Lender evidence of such payment.

      (b) The Borrower will indemnify the Lender for the full amount of Taxes
(including, without limitation, any Taxes imposed by any jurisdiction on amounts
payable under this Section) paid by the Lender and any liability (including
penalties, interest and expenses) arising therefrom or with respect thereto,
whether or not such Taxes were correctly or legally asserted. This
indemnification shall be made within thirty (30) days from the date the Lender
makes written demand therefor.

      (c) If the Lender subsequently recovers, or receives a permanent net tax
benefit with respect to, any amount of Taxes (i) previously paid by it and as to
which it has been indemnified by or on behalf of the Borrower or (ii) previously
deducted by the Borrower (including, without limitation, any Taxes deducted from
any additional sums payable under clause (i) of subsection (a) above), the
Lender shall reimburse the Borrower to the extent of the amount of any such
recovery or permanent net tax benefit (but only to the extent of indemnity
payments made, or additional amounts paid, by or on behalf of the Borrower under
this Section with respect to the Taxes giving rise to such recovery or tax
benefit); provided, however, that the Borrower, upon the request of the Lender,
agrees to repay to the Lender the amount paid over to

                                       23
<PAGE>
the Borrower (together with any penalties, interest or other charges), in the
event the Lender is required to repay such amount to the relevant taxing
authority or other Governmental Authority.

      2.17 Compensation. The Borrower will compensate the Lender upon demand for
all losses, expenses and liabilities (including, without limitation, any loss,
expense or liability incurred by reason of the liquidation or reemployment of
deposits or other funds required by the Lender to fund or maintain LIBOR Loans)
that the Lender may incur or sustain (i) if for any reason the Borrower does not
consummate (other than due to a default by the Lender) a Borrowing or
continuation of, or conversion into, a LIBOR Loan does not occur on a date
specified therefor in a Notice of Borrowing or Notice of
Conversion/Continuation, (ii) if any repayment, prepayment or conversion of any
LIBOR Loan occurs on a date other than the last day of an Interest Period
applicable thereto (including as a consequence of acceleration of the maturity
of the Loans pursuant to SECTION 8.2), (iii) if any prepayment of any LIBOR Loan
is not made on any date specified in a notice of prepayment given by the
Borrower or (iv) as a consequence of any other failure by the Borrower to make
any payments with respect to any LIBOR Loan when due hereunder. Calculation of
all amounts payable to the Lender under this Section shall be made as though the
Lender had actually funded its relevant LIBOR Loan through the purchase of a
Eurodollar deposit bearing interest at the LIBOR Rate in an amount equal to the
amount of such LIBOR Loan, having a maturity comparable to the relevant Interest
Period; provided, however, that the Lender may fund its LIBOR Loans in any
manner it sees fit and the foregoing assumption shall be utilized only for the
calculation of amounts payable under this Section. Determinations by the Lender
for purposes of this Section of any such losses, expenses or liabilities shall,
absent manifest error, be conclusive, provided that such determinations are made
in good faith.

      To induce the Lender to enter into this Agreement and to induce the Lender
to extend the credit contemplated hereby, the Borrower represents and warrants
to the Lender as follows:

      4.1 Corporate Organization and Power. Each of the Borrower and its
Material Subsidiaries (i) is a corporation duly organized, validly existing and
in good standing under the laws of the jurisdiction of its incorporation, (ii)
has the full corporate power and authority to execute, deliver and perform the
Credit Documents to which it is or will be a party, to own and hold its property
and to engage in its business as presently conducted, and (iii) is duly
qualified to do business as a foreign entity and is in good standing in each
jurisdiction where the nature of its business or the ownership of its properties
requires it to be so qualified, except where the failure to be so qualified
would not, individually or in the aggregate, be reasonably likely to have a
Material Adverse Effect.

                                       27
<PAGE>
      4.2 Authorization; Enforceability. The Borrower has taken, or on the
Closing Date will have taken, all necessary corporate action to execute, deliver
and perform each of the Credit Documents to which it is or will be a party, and
has, or on the Closing Date (or any later date of execution and delivery) will
have, validly executed and delivered each of the Credit Documents to which it is
or will be a party. This Agreement constitutes, and each of the other Credit
Documents upon execution and delivery will constitute, the legal, valid and
binding obligation of the Borrower, enforceable against it in accordance with
its terms, except as enforceability may be limited by bankruptcy, insolvency,
reorganization, moratorium or other similar laws affecting creditors' rights
generally, by general equitable principles or by principles of good faith and
fair dealing.

      4.3 No Violation. The execution, delivery and performance by the Borrower
of this Agreement and each of the other Credit Documents to which it is or will
be a party, and compliance by it with the terms hereof and thereof, do not and
will not (i) violate any provision of its articles or certificate of
incorporation or bylaws or contravene any other Requirement of Law applicable to
it, (ii) conflict with, result in a breach of or constitute (with notice, lapse
of time or both) a default under any material indenture, agreement or other
instrument to which it is a party, by which it or any of its properties is bound
or to which it is subject, (iii) result in a revocation, suspension,
termination, impairment, probation, limitation, non-renewal, forfeiture,
declaration of ineligibility, loss of status of, or loss of any other rights
(each a, "License Impairment") with respect to, any Licenses applicable to the
business, operations or properties of the Borrower and its Subsidiaries, except
where such License Impairment would not, individually or in the aggregate, have
a Material Adverse Effect, or (iv) result in or require the creation or
imposition of any Lien upon any of its properties or assets. Except for the
prohibition on Radian Reinsurance Inc. and Radian Asset Assurance Inc. making
any dividend payments to the Borrower prior to February 28, 2003 without the
consent of the New York Insurance Department, no Subsidiary is a party to any
agreement or instrument or otherwise subject to any restriction or encumbrance
that restricts or limits its ability to make dividend payments or other
distributions in respect of its Capital Stock, to repay Indebtedness owed to the
Borrower or any other Subsidiary, to make loans or advances to the Borrower or
any other Subsidiary, or to transfer any of its assets or properties to the
Borrower or any other Subsidiary, in each case other than such restrictions or
encumbrances existing under or by reason of the Credit Documents or applicable
Requirements of Law.

      4.4 Governmental and Third-Party Authorization; Permits.

      (a) No consent, approval, authorization or other action by, notice to, or
registration or filing with, any Governmental Authority or other Person is or
will be required as a condition to or otherwise in connection with the due
execution, delivery and performance by the Borrower of this Agreement or any of
the other Credit Documents to which it is or will be a party or the legality,
validity or enforceability hereof or thereof, other than (i) consents,
authorizations and filings that have been (or on or prior to the Closing Date
will have been) made or obtained and that are (or on the Closing Date will be)
in full force and effect, which consents, authorizations and filings are listed
on SCHEDULE 4.4 and (ii) consents and filings the failure to obtain or make
which would not, individually or in the aggregate, have a Material Adverse
Effect.

                                       28
<PAGE>
      (b) The Borrower and its Subsidiaries have, and are in good standing with
respect to, all governmental approvals, Licenses, permits and authorizations
necessary to conduct its business as presently conducted and to own or lease and
operate its properties, except for those the failure to obtain which would not
be reasonably likely, individually or in the aggregate, to have a Material
Adverse Effect.

      4.5 Litigation. Except as disclosed on SCHEDULE 4.5, there are (i) no
actions, investigations, suits or proceedings pending or, to the knowledge of
the Borrower, threatened, at law, in equity or in arbitration, before any court,
other Governmental Authority, the Insurance Regulatory Authority or other
Person, against or affecting the Borrower or any of its Subsidiaries, or any of
their respective properties that would, if adversely determined, be reasonably
likely to have a Material Adverse Effect, or (ii) no actions, investigations,
suits or proceedings pending or, to the knowledge of the Borrower, threatened,
at law, in equity or in arbitration, before any court, other Governmental
Authority, or other Person, with respect to this Agreement or any of the other
Credit Documents.

      4.6 Taxes. The Borrower and its Subsidiaries have timely filed all federal
tax returns, and all material state and local tax returns and reports required
to be filed by it and have paid all taxes, assessments, fees and other charges
levied upon it or upon its properties that are shown thereon as due and payable,
other than those that are being contested in good faith and by proper
proceedings and for which adequate reserves have been established in accordance
with GAAP. Such returns accurately reflect in all material respects all
liability for taxes of the Borrower and its Subsidiaries for the periods covered
thereby. There is no ongoing audit or examination or, to the knowledge of the
Borrower, other investigation by any Governmental Authority of the tax liability
of the Borrower or any of its Subsidiaries, and there is no unresolved claim by
any Governmental Authority concerning the tax liability of the Borrower or any
of its Subsidiaries for any period for which tax returns have been or were
required to have been filed, other than claims for which adequate reserves have
been established in accordance with GAAP or would not, individually or in the
aggregate, have a Material Adverse Effect. Except as set forth on SCHEDULE 4.6,
neither the Borrower nor any of its Subsidiaries has waived or extended or has
been requested to waive or extend the statute of limitations relating to the
payment of any taxes.

      4.7 Subsidiaries. SCHEDULE 4.7 sets forth a list, as of the date hereof,

information has been amended or supplemented, on the date as of which any such
amendment or supplement is dated or certified) and not made incomplete by

that would violate or be inconsistent with Regulations T, U or X or any
provision of the Exchange Act.

      4.11 Financial Matters.

      (a) The Borrower has heretofore furnished to the Lender copies of (i) the
audited consolidated balance sheets of the Borrower and its Subsidiaries as of
December 31, 2000, 1999, and 1998, and the related statements of income, cash
flows and stockholders' equity for the fiscal years then ended, together with
the opinion of Deloitte & Touche LLP thereon, and (ii) the unaudited
consolidated balance sheet of the Borrower and its Subsidiaries as of September
30, 2001, and the related statements of income, cash flows and stockholders'
equity for the nine-month period then ended. Such financial statements have been
prepared in accordance with GAAP (subject, with respect to the unaudited
financial statements, to the absence of notes required by GAAP and to normal
year-end adjustments) and present fairly the financial condition of the Borrower
and its Subsidiaries on a consolidated basis as of the respective dates thereof
and the consolidated results of operations of the Borrower and its Subsidiaries
for the respective periods then ended. Except as fully reflected in the most
recent financial statements referred to above and the notes thereto, there are
no material liabilities or obligations with respect to the Borrower or any of
its Subsidiaries of any nature whatsoever (whether absolute, contingent or
otherwise and whether or not due).

      (b) Each of the Borrower and its Subsidiaries, after giving effect to the
consummation of the transactions contemplated hereby, (i) has capital sufficient
to carry on its businesses as conducted and as proposed to be conducted, (ii)
has assets with a fair saleable value, determined on a going concern basis, (y)
not less than the amount required to pay the probable liability on its existing
debts as they become absolute and matured and (z) greater than the total amount
of its liabilities (including identified contingent liabilities, valued at the
amount that can reasonably be expected to become absolute and matured), and
(iii) does not intend to, and does not believe that it will, incur debts or
liabilities beyond its ability to pay such debts and liabilities as they mature.

      (c) The Borrower has heretofore furnished to the Lender copies of (i) the
Annual Statements of each of its Material Insurance Subsidiaries as of December
31, 2000, 1999 and 1998, and for the fiscal years then ended, and (ii) the
Quarterly Statements of each of its Material Insurance Subsidiaries as of the
end of the first three fiscal quarters of 2001, and for the fiscal

                                       30
<PAGE>
quarters then ended, each as filed with the relevant Insurance Regulatory
Authority (collectively, the statements referenced in clauses (i) and (ii)
above, the "Historical Statutory Statements"). The Historical Statutory
Statements (including, without limitation, the provisions made therein for
investments and the valuation thereof, reserves, policy and contract claims and
statutory liabilities) have been prepared in accordance with SAP where required
(except as may be reflected in the notes thereto and subject, with respect to
the Quarterly Statements, to the absence of notes required by SAP and to normal
year-end adjustments), were in compliance in all material respects with
applicable Requirements of Law when filed and present fairly the financial
condition of the respective Insurance Subsidiaries covered thereby as of the
respective dates thereof and the results of operations, changes in capital and
surplus and cash flow of the respective Insurance Subsidiaries covered thereby
for the respective periods then ended. Except for liabilities and obligations
disclosed or provided for in the Historical Statutory Statements (including,
without limitation, reserves, policy and contract claims and statutory
liabilities), no Insurance Subsidiary had, as of the date of its respective
Historical Statutory Statements, any material liabilities or obligations of any
nature whatsoever (whether absolute, contingent or otherwise and whether or not
due) that, in accordance with SAP, would have been required to have been
disclosed or provided for in such Historical Statutory Statements. All books of
account of each Insurance Subsidiary fully and fairly disclose all of its
material transactions, properties, assets, investments, liabilities and
obligations, are in its possession and are true, correct and complete in all
material respects.

      (d) Within the last three (3) years, neither the Borrower nor any of its
Subsidiaries has received any "management letter" from any certified public
accountants in connection with any annual, interim or special audit that
disclosed any findings that were material and adverse to the Borrower.

interests as lessee under valid leases in full force and effect with respect to
all material leased real and personal property used in connection with its
business, (iii) possesses or has rights to use licenses, patents, copyrights,

to continue to conduct its business substantially as heretofore conducted and
without any material conflict with the rights of others, and (iv) has good title
to all of its other properties and assets reflected in the most recent financial
statements referred to in SECTION 4.11 (except as sold or otherwise disposed of

      (a) Each of the Borrower and its ERISA Affiliates is in compliance in all
material respects with the applicable provisions of ERISA, and each Plan is and
has been administered in compliance in all material respects with all applicable
Requirements of Law, including, without limitation, the applicable provisions of
ERISA and the Internal Revenue Code. No ERISA Event (i) has occurred within the
five-year period prior to, and including, the Closing Date, or (ii) to the
knowledge of the Borrower, is reasonably expected to occur with respect to any
Plan. No Plan has any Unfunded Pension Liability as of the most recent annual
valuation date applicable

                                       31
<PAGE>
thereto, and neither the Borrower nor any ERISA Affiliate has engaged in a
transaction that could be subject to Section 4069 or 4212(c) of ERISA.

      (b) Neither the Borrower nor any ERISA Affiliate has had a complete or
partial withdrawal from any Multiemployer Plan, and neither the Borrower nor any
ERISA Affiliate would become subject to any liability under ERISA if the
Borrower or any ERISA Affiliate were to withdraw completely from all
Multiemployer Plans as of the most recent valuation date. No Multiemployer Plan
is in "reorganization" or is "insolvent" within the meaning of such terms under
ERISA.

generated, used, located, released, treated, disposed of or stored by the
Borrower or any of its Subsidiaries or, to the knowledge of the Borrower, by any
other Person (including any predecessor in interest) or otherwise, in, on or
under any portion of any real property, leased or owned, of the Borrower or any
of its Subsidiaries, except in material compliance with all applicable
Environmental Laws, and no portion of any such real property or, to the
knowledge of the Borrower, any other real property at any time leased, owned or
operated by the Borrower or any of its Subsidiaries has been contaminated by any

the Borrower or any of its Subsidiaries has been or is presently the subject of
an environmental audit, assessment or remedial action.

any of its Subsidiaries has been used by the Borrower or any of its Subsidiaries
or, to the knowledge of the Borrower, by any other Person, as or for a mine, a
landfill, a dump or other disposal facility, a gasoline service station, or
(other than for petroleum substances stored in the ordinary course of business)
a petroleum products storage facility; no portion of such real property or any
other real property at any time leased, owned or operated by the Borrower or any
of its Subsidiaries has, pursuant to any Environmental Law, been placed on the
"National Priorities List" or "CERCLIS List" (or any similar federal, state or
local list) of sites subject to possible environmental problems; and there are
not and have never been, any underground storage tanks situated on any real
property, leased or owned, of the Borrower or any of its Subsidiaries.

      (c) All activities and operations of the Borrower and its Subsidiaries are
in compliance with the requirements of all applicable Environmental Laws, except
to the extent the failure so to comply, individually or in the aggregate, would
not be reasonably likely to have a Material Adverse Effect. Each of the Borrower
and its Subsidiaries has obtained all licenses and permits under Environmental
Laws necessary to its respective operations; all such licenses and permits are
being maintained in good standing; and each of the Borrower and its Subsidiaries
is in compliance with all terms and conditions of such licenses and permits,
except for such licenses and permits the failure to obtain, maintain or comply
with which would not be reasonably likely, individually or in the aggregate, to
have a Material Adverse Effect. Neither the Borrower nor any of its Subsidiaries
is involved in any suit, action or proceeding, or has received any notice,
complaint or other request for information from any Governmental Authority or
other Person, with respect to any actual or alleged Environmental Claims that,
if adversely determined, would be reasonably likely, individually or in the
aggregate, to have a Material Adverse Effect; and, to the knowledge of either
Borrower, there are no threatened actions, suits, proceedings or investigations
with respect to any such Environmental Claims, nor any basis therefor.

timely filed all material reports, documents and other materials required to be
filed by it under all applicable Requirements of Law with any Governmental
Authority and Insurance Regulatory Authority, as the case may be, has retained
all material records and documents required to be retained by it under all
applicable Requirements of Law, and is otherwise in compliance with all
applicable Requirements of Law in respect of the conduct of its business and the
ownership and operation of its properties, except for such Requirements of Law
the failure to comply with which, individually or in the aggregate, would not be
reasonably likely to have a Material Adverse Effect.

      4.16 Regulated Industries. Neither the Borrower nor any of its
Subsidiaries is (i) an "investment company," a company "controlled" by an
"investment company," or an "investment advisor," within the meaning of the
Investment Company Act of 1940, as amended, or (ii) a "holding company," a
"subsidiary company" of a "holding company," or an "affiliate" of a "holding
company" or of a "subsidiary company" of a "holding company," within the meaning
of the Public Utility Holding Company Act of 1935, as amended.

      4.17 Insurance. The assets, properties and business of the Borrower and
its Subsidiaries are insured against such hazards and liabilities, under such
coverages and in such amounts, as are customarily maintained by prudent
companies similarly situated and under policies issued by insurers of recognized
responsibility.

      4.18 Material Contracts. SCHEDULE 4.18 lists, as of the Closing Date, each
"material contract" (within the meaning of 601(b)(10) of Regulation S-K under
the Exchange Act other than, to the extent applicable, any contract involving an
employee loan in an amount less than $60,000) that is not listed in the
Borrower's most recent annual report filed on Form 10-K or any quarterly report
filed on Form 10-Q since that time and to which the Borrower or any of its
Subsidiaries is a party, by which any of them or their respective properties is

Closing Date, (i) each Material Contract is in full force and effect and is
enforceable by the Borrower or the applicable Subsidiary in accordance with its
terms, and (ii) neither the Borrower nor any of its Subsidiaries (nor, to the
knowledge of the Borrower, any other party thereto) is in breach of or default
under any Material Contract in any material respect or has given notice of
termination or cancellation of any Material Contract.

Annual Statements for the Material Insurance Subsidiaries, for the fiscal year
ending December 31, 2000, and except as set forth on SCHEDULE 4.19, there were
no material liabilities outstanding as of September 30, 2001 under any
Reinsurance Agreement and since September 30, 2001, except as previously
disclosed in writing by the Borrower to the Lender pursuant to this Agreement,
and no Material Insurance Subsidiary has incurred any material liabilities under
any Reinsurance Agreement that, individually or in the aggregate, could
reasonably be expected to have a Material Adverse Effect. Each such Reinsurance
Agreement (except any Reinsurance Agreement that has expired by its terms in the
ordinary course) is in full force and effect; none of the Material Insurance
Subsidiaries or, to the knowledge of the Borrower, any other party thereto, is
in breach of or default under any such contract; and the Borrower has no reason
to believe that the financial condition of any other party to any such contract
is impaired such that a

                                       33
<PAGE>
default thereunder by such party could reasonably be anticipated. Each such
Reinsurance Agreement (except any Reinsurance Agreement that has expired by its
terms in the ordinary course) is qualified under all applicable Requirements of
Law to receive the statutory credit assigned to such Reinsurance Agreement in
the relevant Annual Statement or Quarterly Statement at the time prepared.

      Acquisition and the applicable conditions and requirements of SECTION 5.9
      shall be satisfied, and (z) immediately after giving effect thereto, no
      Default or Event of Default would exist; and

            (ii) any Subsidiary may merge or consolidate with another Person so
      long as (x) the surviving entity is the Borrower or a Subsidiary, (y)
      unless such other Person is a Wholly Owned Subsidiary immediately prior to

      Permitted Acquisition and the applicable conditions and requirements of

      paid when due except to the extent being contested in good faith and by
      appropriate proceedings;

            (iv) Indebtedness of any Subsidiary to the Borrower; provided that

            (v) Indebtedness of any Subsidiary to any wholly-owned Subsidiary of
      the Borrower; provided that that no Default has occurred and is continuing
      and no Default shall occur as a result of the incurrence of such

            (vi) purchase money Indebtedness of the Borrower and its

      Indebtedness is subordinated in right and time of payment to the
      Obligations, in form and substance reasonably satisfactory to the Lender.

      any particular date will cause a Default hereunder, such new Indebtedness,
      along with any other Indebtedness outstanding as of such date, shall be
      deemed to be the outstanding Indebtedness as of the last day of the
      previous fiscal quarter; and

      Default shall occur as a result of the incurrence of such Indebtedness.

      9.7 Assignments, Participations.

      (a) The Lender may assign to one or more assignees (each, an "Assignee")
all or a portion of its rights and obligations under this Agreement (including,
without limitation, all or a portion of its Commitment, the outstanding Loans
made by it, the Note held by it); provided, however, that any such assignment
(other than an assignment to an Affiliate of the Lender) shall not be made
without the prior written consent of the Borrower, which consent shall not be
unreasonably withheld (provided that the Borrower's consent shall not be
required in the event a Default or Event of Default shall have occurred and be
continuing).

      (b) The Lender may, without the consent of the Borrower, sell to one or
more other Persons (each, a "Participant") participations in any portion
comprising less than all of its rights and obligations under this Agreement
(including, without limitation, a portion of its Commitment, the outstanding
Loans made by it, the Note); provided, however, that the Lender's obligations
under this Agreement shall remain unchanged and the Lender shall remain solely
responsible for the performance of such obligations, and no Participant shall
have any rights under this Agreement or any of the other Credit Documents, each
Participant's rights against the

                                       51
<PAGE>
Lender in respect of any participation to be those set forth in the
participation agreement, and all amounts payable by the Borrower hereunder shall
be determined as if the Lender had not granted such participation.

      (c) Nothing in this Agreement shall be construed to prohibit the Lender
from pledging or assigning all or any portion of its rights and interest

borrowings therefrom; provided, however, that no such pledge or assignment shall
release the Lender from any of its obligations hereunder.

participation or proposed assignment or participation pursuant to this Section,
disclose to the Assignee or Participant or proposed Assignee or Participant any

cumulative and in addition to, and not exclusive of, all other rights and
remedies available at law, in equity or otherwise. No failure or delay on the
part of either party hereto in exercising any right, power or privilege shall
operate as a waiver thereof, nor shall any single or partial exercise of any
such right, power or privilege preclude other or further exercise thereof or the
exercise of any other right, power or privilege or be construed to be a waiver
of any Default or Event of Default. No course of dealing between the Borrower
and the Lender or their agents or employees shall be effective to amend, modify
or discharge any provision of this Agreement or any other Credit Document or to
constitute a waiver of any Default or Event of Default. No notice to or demand

notice or demand in similar or other circumstances or constitute a waiver of the

action in any circumstances without notice or demand.

on behalf of the Borrower or any of its Subsidiaries in this Agreement and in

confidential nature of such information), (ii) at the demand or request of any
bank regulatory authority, court, other Governmental Authority or Insurance
Regulatory Authority having or asserting jurisdiction over the Lender, as may be
required pursuant to subpoena or other legal process, or otherwise in order to
comply with any applicable Requirement of Law (provided that, to the extent
reasonably possible, the Borrower is provided with timely notice of such demand
or request so that the Borrower may seek an appropriate protective order with
the reasonable cooperation of the Lender (at the Borrower's expense)), (iii) in
connection with any proceeding to enforce its rights hereunder or under any
other Credit Document or any other litigation or proceeding related hereto or to
which it is a party, (iv) to the extent the same has become publicly available

      IN DECEMBER 2000, A COMPLAINT SEEKING CLASS ACTION STATUS ON BEHALF OF A
NATIONWIDE CLASS OF HOME MORTGAGE BORROWERS WAS FILED AGAINST RADIAN GUARANTY
INC. IN THE UNITED STATES DISTRICT COURT FOR THE MIDDLE DISTRICT OF NORTH
CAROLINA (GREENSBORO DIVISION). THE COMPLAINT ALLEGES THAT RADIAN GUARANTY INC.
VIOLATED SECTION 8 OF RESPA. THE COMPLAINT ASSERTS THAT THE PRICING OF POOL
INSURANCE, CAPTIVE REINSURANCE CONTRACT UNDERWRITING, PERFORMANCE NOTES AND
OTHER UNIDENTIFIED STRUCTURED TRANSACTIONS, SHOULD BE INTERPRETED AS IMPUTED
KICKBACKS MADE IN EXCHANGE FOR THE REFERRAL OF PRIMARY MORTGAGE INSURANCE
BUSINESS, WHICH ACCORDING TO THE COMPLAINT, IS A SETTLEMENT SERVICE UNDER RESPA.
THE COMPLAINT SEEKS INJUNCTIVE RELIEF AND DAMAGES OF 3X THE AMOUNT OF ANY
MORTGAGE INSURANCE PREMIUMS PAID BY PERSONS WHO WERE REFERRED TO RADIAN GUARANTY
INC. TO THE ALLEGED AGREEMENT OR UNDERSTANDING. THE PLAINTIFFS IN THE LAWSUIT
ARE REPRESENTED BY THE SAME GROUP OF PLAINTIFFS' ATTORNEYS WHO FILED SIMILAR
LAWSUITS AGAINST OTHER PROVIDERS OF PRIMARY MORTGAGE INSURANCE IN FEDERAL COURT
IN GEORGIA. THE GEORGIA COURT DISMISSED THOSE SUITS FOR A FAILURE TO STATE A
CLAIM. THREE OF THOSE LAWSUITS WERE SETTLED PRIOR TO APPEAL; TWO ARE CURRENTLY
ON APPEAL. RADIAN GUARANTY HAS RESPONDED TO THE COMPLAINT BY FILING A MOTION TO
DISMISS.

      A SIMILAR ACTION FOCUSING ON POOL INSURANCE WAS FILED IN FEBRUARY 2001 IN
THE UNITED STATES DISTRICT COURT FOR THE EASTERN DISTRICT OF TEXAS.
