               FIRST AMENDMENT TO THE AMENDED AND RESTATED LIMITED
                 LIABILITY COMPANY AGREEMENT OF ROXBURY CAPITAL
                                 MANAGEMENT, LLC

         WHEREAS, an Amended and Restated Limited Liability Company Agreement
(the "Agreement") was made as of July 31, 1998 by and among Roxbury Capital
Management (Roxbury), WT Investments, Inc. (WTI), the Principals (as defined in
the Agreement) and Wilmington Trust Corporation (Wilmington) to govern the
operation of Roxbury Capital Management, LLC (the "LLC");

         WHEREAS, the Members of the LLC desire to amend the Agreement pursuant
to Section 14.1 of the Agreement;

         NOW, THEREFORE, in consideration of the agreements and obligations set
forth herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the Members of the LLC, intending
to be legally bound, hereby agree to amend the Agreement as follows:

         1.       Each capitalized term used, but not defined, in this First
                  Amendment shall have the meaning assigned to it in the
                  Agreement.

         2.       Section 1.72 of the Agreement is amended as follows:

         1.72 "Revenues" means the gross receipts of the LLC from whatever
source, including without limitation gross receipts from the sale of assets;
provided, however, that Revenues shall not include gross receipts from the sale
of all or substantially all of the LLC's assets or the deemed sale of the LLC's
assets in connection with the liquidation of the LLC AND SHALL NOT INCLUDE
WILMINGTON FUND REVENUE.

         3.       Section 1 of the Agreement is amended by adding a new Section
                  1.92 as follows:

1.92 "WILMINGTON FUND REVENUE" MEANS, AFTER 1999, THE LESSER OF $[*], OR ANY
ADVISORY FEES, MINUS ANY ADVISORY FEE WAIVERS, EARNED BY THE LLC PURSUANT TO AN
INVESTMENT ADVISORY AGREEMENT WITH THE WILMINGTON LARGE CAP GROWTH PORTFOLIO FOR
MANAGEMENT OF ASSETS HELD IN THAT MUTUAL FUND. IN 1999 WILMINGTON FUND REVENUE
SHALL BE $[*].

         4.       Section 6.3(a) of the Agreement is amended as follows:

6.3      Distributions.

                  (a) Except as provided in Section 6.3(f), within 90 days after
the end of each Fiscal Year, the Board shall cause to be distributed:

* CONFIDENTIAL TREATMENT REQUESTED
<PAGE>

                  (i) first, to the Preferred Members in proportion to their
respective number of Preferred Membership Points, (A) [ * ]% of all Revenues of
the LLC for that Fiscal Year ("Preferred Member Revenue Share") PLUS (B)
WILMINGTON FUND REVENUE less (C) the Excess Cash Flow Split for such Fiscal
Year.

                  (ii) second, the "Excess Cash Flow Split" shall be paid to the
Common Members in proportion to their respective number of Common Membership
Points beginning with distributions with respect to Fiscal Year 1999.

                           A) For the Fiscal Years 1999, 2000, 2001 and 2002,
                  multiply annual Advisory Fee revenue in 1998 by [ * ] ("Hurdle
                  Rate") taken to the "N"th power, where "N" is 1 with respect
                  to Fiscal Year 1999, "N" is 2 with respect to Fiscal Year
                  2000, "N" is 3 with respect to Fiscal Year 2001 and "N" is 4
                  with respect to Fiscal Year 2002. Annual Advisory Fee revenue
                  in 1998 shall be all 1998 advisory fee revenue earned by
                  Roxbury plus all 1998 Advisory Fee revenue earned by the LLC.
                  With respect to Fiscal Years 2003 and thereafter, the Excess
                  Cash Flow Split shall be computed by multiplying the Advisory
                  Fee revenue (EXCLUDING ANY WILMINGTON FUND REVENUE) for the
                  fifth prior Fiscal Year (for example, with respect to Fiscal
                  Year 2003, use Advisory Fee revenue for Fiscal Year 1998) by
                  [ * ] (which is [ * ]). An amount computed hereunder is
                  "Assumed Fee Income" for such Fiscal Year.

                           B) Subtract the Assumed Fee Income for such Fiscal
                  Year from the actual Advisory Fee revenue for such Fiscal
                  Year, EXCLUDING ANY WILMINGTON FUND REVENUE.

                           C) If the calculation in B) produces a positive
                  number, multiply that difference by [ * ]. The product of this
                  multiplication is the Excess Cash Flow Split. (See examples in
                  Exhibit B.)

                  (iii) third, Fee Cash Flow shall be paid to the Common Members
in proportion to their respective number of Common Membership Points for such
Fiscal Year.

         5.       Section 7.1(d) of the Agreement is amended to read as follows:

         (b) Until December 31, 2003, Roxbury may grant options on LLC Interests
it owns to employees of the LLC in Roxbury's sole and absolute discretion
pursuant to a written Option Agreement if: (i) the aggregate exercise price to
purchase the LLC Interests subject to the option is not less than the
proportionate share of LLC Value represented by such LLC Interests determined on
the date of the grant using a multiple of [ * ] in determining LLC Value; (ii)
not more than one-third of the option shall vest before the end of the first
year after grant, not more than two-thirds of the option shall vest before the
end of the second year after grant, and not more than 100% of the option shall
vest before the end of the third year after grant; (III) the option holder
executes an employment contract in a form acceptable to the LLC at the time of,
or prior to, the execution of the Option Agreement; (IV) the option holder
exercising the option must

sign this Agreement as a condition of exercise; and (V) the optionee makes
representations and warranties to the LLC comparable to those contained in
Section 13.5 on the date of grant of the option and on the date of each exercise
thereof.

         6. Schedule I of the Agreement is hereby amended and replaced with the
Schedule I attached hereto.

         IN WITNESS WHEREOF, the parties hereto have executed this Agreement as
of the date first above stated.

9                  (k) "Oregon Gross Revenue" means, for any accounting period,

may elect, by written notice delivered to the LLC within 15 days after receipt

("Class B Accountants") at the Class B Members' expense, to review the LLC's

Oregon FCF. If, within 30 days after the Class B Members' delivery of the Class
B Accountant's calculation of Oregon FCF, the LLC and the Class B Members have
not reached an agreement as to the Oregon FCF for such preceding Fiscal Year,
the LLC and the Class B Members shall engage a third, unaffiliated independent
accounting firm ("Independent Accountants") to calculate the Oregon FCF. The
decision of the Independent Accountants shall be final and binding. The LLC and
the Class B Members shall share the costs and expenses associated with the
engagement of the Independent Accountants. If the Independent Accounts determine
that the Oregon FCF is more than 105% of the determination of the LLC
Accountants, then the LLC shall be responsible for the costs of the Independent
Accountants, and shall reimburse the Class B Members for the reasonable costs of
the Class B Accountants.

                  (d) Within 10 business days after the end of each calendar
quarter, the Board shall cause to be distributed to the Class B Members, pro
rata in accordance with their respective holdings of outstanding Class B
Membership Points, not less than forty percent (40%) of the estimated
undistributed Oregon Manager FCF (if any) applicable to such quarter of each
Fiscal Year.

                  (e) Within 75 days after the end of each Fiscal Year, the
Board shall cause to be distributed to the Class B Members, pro rata in
accordance with their respective holdings of outstanding Class B Membership
Points, the theretofore undistributed portion of Oregon Manager FCF (if any)
applicable to such Fiscal Year. If the distributions to Class B Members during
any Fiscal Year exceed the Oregon Member

                                       4
<PAGE>
FCF applicable to such Fiscal Year, then the Class B Members shall return any
such excess to the LLC within 75 days after the end of such Fiscal Year.

                  (f) The LLC shall not make any distributions to the Class B
Members that violate Section 18-607 of the Delaware Act or other applicable law.

                  (g) There shall be allocated to the Class B Members, pro rata
with respect to their holdings of Class B Membership Points, profits equal to
the Oregon Manager FCF. No other profits or losses shall be allocated to the
Class B Members. All other profits and losses of the LLC, including the other
fifty percent (50%) of the Oregon Surplus FCF, shall be allocated as otherwise
provided in Sections 6.3 and 6.4 of this Agreement.

                  (h) Section 6.7 of this Agreement shall apply to the Class B
Members and their respective Class B Membership Points on the same terms as set
forth in respect of the Common Members and their respective Common Membership
Points.

         15.3 Put Right. At any time and from time to time during each Put
Window, each Class B Member shall have the right to sell to Wilmington, and
Wilmington shall have the obligation to purchase, for the B Put Price (payable
to such Class B Member within 15 days after the end of the applicable Put
Window, such amount to accrue simple interest at the prime rate if unpaid at the
end of such 15-day period until such amount is paid) a portion of the Class B
Membership Points then held by such Class B Member; provided, however, that no
Class B Member shall sell pursuant to this Section 15.3 more than fifty percent
(50%) of the aggregate Class B Membership Points issued initially to such Class
B Member. Notwithstanding the foregoing, if the total number of Class B
Membership Points elected to be sold during any Put Window pursuant to this
Section 15.3 by all Class B Members (the "Total Class B Election") exceeds
twenty-five percent (25%) of the aggregate number of Class B Membership Points
issued initially to all Class B Members (the "Yearly Limit"), then each Class B
Member may sell pursuant to this Section 15.3 that number of his Class B
Membership Points equal to the Yearly Limit multiplied by a fraction, the
numerator of which is the number of Class B Membership Points elected to be sold
by such Class B Member, and the denominator of which is the Total Class B
Election during such Put Window.

         15.4 Transfer. Class B Members shall be permitted to make Transfers of
Class B Membership Interests as provided in Section 7.1(b) of the Agreement.

         15.5 Reorganization. If at any time or from time to time there shall be
a reorganization or other change in the business structure of the LLC, including
without limitation a conversion to a subchapter "C" corporation (a "Structure
Change") approved by the Board, then each Class B Member shall exchange such
Class B Member's Class B Membership Interest for the applicable interest in the
resulting entity (the "Exchange Interest") as determined by the Board; provided,
however, that any such Exchange Interest shall have economic rights and
characteristics substantially equivalent to the applicable Class B Membership
Interest (including with respect to distributions of Oregon Manager FCF and
sales of Class B Membership Interests).

         15.6 Sale on Termination.

                  (a) If (i) the LLC terminates the employment of any Class B
Member (x) without Cause, (y) pursuant to either Sections 5.1(e) or 5.1(f) of
such Class B Member's Employment Agreement, or (z) pursuant to the LLC's
election not to renew the Term in accordance with Section 1 of such Class B
Member's Employment Agreement, or (ii) such Class B Member terminates his
employment with the LLC (x) for Good Reason, (y) such employment terminates by
reason of such Class B Member's death or Disability, or, (z) pursuant to and in
accordance with Section 7.3 of Exhibit A to such Class B Member's Employment
Agreement if such employment is terminated by such Class B Member, with at least
six months prior written notice, and with such termination to be effective not
earlier than the Outside Termination Date, or (iii) the LLC sells all or
substantially all of its assets or is deemed to have sold all of its assets in a
liquidation, then such Class B Member (or his successors or legal
representatives, as applicable) shall sell, and Wilmington shall purchase, all
of such Class B Member's Class B Membership Points for a purchase (payable to
such Class B Member within 15 days after any such event occurs, such amount to
accrue simple interest at the prime rate if unpaid at the end of such 15-day
period until such amount is paid) price equal to [ * ] multiplied by the
Oregon Manager FCF for the twelve full calendar months immediately preceding the
effective date of such termination, or the closing of such sale or deemed sale
(as the case may be), multiplied by a fraction, the numerator of which is the
total number of Class B Membership Points then owned by such Class B Member, and
the denominator of which is the total number of Class B Membership Points then
outstanding.

                  (b) If (i) the LLC terminates the employment of any Class B
Member for Cause, or if (ii) such employment is terminated by such Class B
Member (x) without Good Reason, or (y) pursuant to such Class B Member's
election not to renew the Term in accordance with Section 1 of such Class B
Member's Employment Agreement prior to the Outside Termination Date, then such
Class B Member shall sell, and Wilmington shall purchase, all of such Class B
Member's Class B Membership Points for a purchase price (payable to such Class B
Member within 15 days after any such event occurs, such amount to accrue simple
interest at the prime rate if unpaid at the end of such 15-day period until such
amount is paid) equal to [ * ] multiplied by the Oregon Manager FCF for the
twelve full calendar months immediately preceding the effective date of such
termination multiplied by a fraction, the numerator of which is the total number
of Class B Membership Points then owned by such Class B Members, and the
denominator of which is the total number of Class B Membership Points then
outstanding.

                  (c) As used in this Section 15.6, the terms "Cause", "Good
Reason", "Term", and "Disability", shall all have the meanings set forth in the
applicable Employment Agreement between any Class B Member and the LLC (the
"Employment Agreement"). Any and all determinations concerning any such
termination of employment of a Class B Member shall be made pursuant to such
applicable Employment Agreement.
