                                   WITNESSETH:

         WHEREAS, the Company and FUI are parties to the certain Bridge Note

pursuant to which the Purchaser (as defined below) purchased a 13% senior
subordinated bridge note from the Company (the "Note");

         WHEREAS, the Company wishes to grant a conversion option to the
Purchaser whereby the Purchaser may, at its option, convert the Note (including
PIK Notes, if any) and accrued and unpaid interest thereon into the type and
kind of securities issued in an Equity Financing (as defined below); and

         WHEREAS, in the event the Company redeems the Note with the proceeds of

         employee of the Company or its affiliates of stock options to purchase

                  SECTION 2. CONVERSION OPTION.

                  (a)      Until February 14, 2001, if the Company shall
                  initiate any transaction or be a party to any agreement or
                  transaction resulting in any Equity Financing, then, as a
                  condition of the consummation of all such Equity Financings,
                  lawful, enforceable and adequate provision shall be made so
                  that the Purchaser shall be entitled to elect, at its option,
                  by written notice to the Company to convert the sum of the
                  unpaid principal amount of the Note (including PIK Notes, if
                  any) plus all accrued and unpaid interest thereon (the
                  "Aggregate Note Amount") into fully paid and non-assessable
                  securities of the identical price, type and kind of securities
                  received by the purchasers in such Equity Financings. The
                  number of securities to be received shall be determined by
                  dividing the Aggregate Note Amount by the identical per share
                  price being paid for the securities by the ultimate purchasers
                  in the Equity Financing. The above provisions of this Section
                  2(a) shall apply to all Equity Financings which occur on or
                  prior to February 14, 2001; provided, that if the Company has
                  initiated or become a party to any agreement or transaction
                  before February 14, 2001 which will result in an Equity
                  Financing being consummated after February 14, 2001, then this
                  Section 2(a) shall continue to apply until the consummation of
                  such Equity Financing; provided, however, upon the closing of
                  a Qualified Public Offering, the Aggregate Note Amount shall
                  be automatically converted into fully paid and non-assessable
                  securities of the identical price, type and kind of securities
                  received in the Qualified Public Offering. The Company shall
                  give written notice to the Purchaser no less than 20 days
                  prior to the closing of such Equity Financing. Such notice
                  shall contain all the material terms, including, but not
                  limited to, the price, quantity and rights of the applicable
                  security, of the Equity Financing.

                  (b)      In order to exercise the conversion privilege, the
                  Purchaser of any note to be converted shall on or before the
                  10th day after receipt of the Company's notice of an Equity
                  Financing surrender such note, duly endorsed or assigned to
                  the Company or in blank at any office or agency of the
                  Company, accompanied by written notice to the Company at such
                  office or agency that the Purchaser elects to convert such
                  note or, if less than the entire principal amount thereof is
                  to be converted, the portion thereof to be converted. Notes
                  shall be deemed to have


                                       3
<PAGE>   4

                  been converted immediately prior to the close of business on
                  the day of surrender of such notes for conversion in
                  accordance with the foregoing provisions, and at such time the
                  rights of the Purchaser of such notes as Purchaser shall
                  cease, and the Person or Persons entitled to receive the
                  securities issuable upon conversion shall be treated for all
                  purposes as the record purchaser or purchasers of such
                  securities at such time. As promptly as practicable on or
                  after the conversion date, the Company shall issue and shall
                  deliver at such office or agency a certificate or certificates
                  for the number of full shares of securities issuable upon
                  conversion, together with payment in lieu of any fraction of a
                  share, as provided in Section 1(c). In the case of any note
                  that is converted in part only, upon such conversion the
                  Company shall execute a new note in aggregate principal amount
                  equal to the unconverted portion of the principal amount of
                  such note.

                  (c)      No fractional shares of securities shall be issued
                  upon conversion of the note. If more than one note shall be
                  surrendered for conversion at one time by the same Purchaser,
                  the number of full shares that shall be issuable upon
                  conversion thereof shall be computed on the basis of the
                  aggregate principal amount of the notes (or, specified
                  portions thereof) so surrendered. Instead of any securities
                  that would otherwise be issuable upon conversion of any note
                  or notes (or, specified portions thereof), the Company shall
                  pay a cash adjustment in respect of such fraction in an amount
                  equal to the same fraction of the per share purchase price of
                  a share of such securities.

                  (d)      As a condition of the exercise of the conversion
                  right, the Purchaser shall execute and become a party to all
                  documents involved in such Equity Financing which are
                  reasonably acceptable to the Purchaser and are executed by
                  other purchasers in such Equity Financing (including, without
                  limitation, shareholder agreements, registration rights
                  agreements, purchase agreements, and, if such Equity Financing
                  is a Qualified Public Offering, a 180-day lock-up agreement).

         SECTION 3. RIGHT TO INVEST IN EQUITY FINANCINGS.

                  (a)      Right to Invest. In the event the Company redeems
                  all or any portion of the Note (or PIK Notes, if any) on or
                  before February 14, 2001, from the proceeds of a source of
                  funds other than an Equity Financing, and in the event the
                  Company conducts any Equity Financing during the 12 months
                  after the date of redemption, then the Company hereby agrees
                  to give prior written notice to the Purchaser and grants to
                  the Purchaser the option to purchase securities issued in such
                  Equity Financing with an aggregate purchase price equal to the
                  Allocable Portion, at the price and upon the same terms set
                  forth in such transaction. Such options shall be exercisable
                  by written notice to the Company for a period of 20 days from
                  the date of such offer and shall follow the procedures set
                  forth in Sections 2(b), 2(c) and 2(d). The closing of the
                  purchase of such securities by the Purchaser shall take place
                  concurrently with the closing of such Equity Financing.


                                       4
<PAGE>   5

                  (b)      As a condition of the exercise of the rights under
                  this Section 3, the Purchaser shall execute and become a party
                  to all documents involved in such Equity Financing which are
                  reasonably acceptable to the Purchaser and are executed by the
                  other purchasers in such Equity Financing (including, without
                  limitation, shareholder agreements, registration rights
                  agreements, purchase agreements, etc.).

         SECTION 4. MERGER OR SIMILAR TRANSACTION. If, on or before February 14,
2001, the Company shall merge, consolidate, exchange or close any similar
transaction with an unaffiliated entity which does not have a class of equity
securities registered under the Securities Exchange Act of 1934, as amended (the
"Acquiring Company"), in any such case where securities of the Acquiring Company
are being issued in exchange for, or otherwise in return for, all or
substantially all of the outstanding securities of the Company (a "Sale
Transaction"), the Purchaser shall have the right to convert all or a portion of
the outstanding principal and accrued interest on the Notes into shares of the
Class A common stock of the Company, in the manner set forth in Section 2 above.
The number of shares of the Class A common stock of the Company to be issued in
connection with such conversion shall be equal to the dollar amount of the Notes
to be converted, divided by the transaction per share value of a share of the
Company's Class A common stock in the Sale Transaction. The Purchaser shall
execute all documents reasonably required to be signed by the holders of the
Class A common stock in connection with the Sale Transaction. The Company shall
provide the Purchaser with written notice of the proposed Sale Transaction
within 20 days prior to the closing thereof. Such notice shall contain all the
material terms, including, but not limited to, the price, quantity and rights of
the applicable security, of the Equity Financing. If the Purchaser desires to
convert all or a portion of the Notes, it shall provide written notice to the
Company within 10 days after receipt of the Company's notice. Upon the closing
of the Sale Transaction, the Purchaser, shall have no other rights pursuant to
Sections 2 or 3 of this Agreement.

         SECTION 5. ASSIGNABILITY; SUCCESSORS AND ASSIGNS. Neither the Company
nor the Purchaser may assign or transfer (by operation of law or otherwise) its
rights and obligations, in whole or in part, under this Agreement to any third
party without the prior written consent of the other party; provided, however,
that the Purchaser may assign such rights and obligations to an affiliate of the
Purchaser without obtaining such consent. The rights and obligations of the
Purchaser and the Company hereunder shall inure to the benefit of, and be
binding and enforceable upon, the respective successors, and permitted assigns
or transferees of the Purchaser and the Company.

         SECTION 6. REMEDIES. The Company stipulates that the remedies at law of
the Purchaser in the event of any default or threatened default by the Company
in the performance of or compliance with any of the terms of this Agreement are
not and will not be adequate, and that such terms may be specifically enforced
by a decree for the specific performance of any agreement contained herein or by
an injunction against a violation of any of the terms hereof or otherwise.


                                       5
<PAGE>   6

         SECTION 7. NOTICES. Except as otherwise provided herein, any notices
hereunder shall be deemed to have been received (a) when delivered, if
personally delivered or sent via facsimile, or (b) one day following delivery to
a nationally recognized overnight courier or (c) on the third business day
following the date on which the piece of mail containing such communication is
posted, if sent by certified or registered mail, return receipt requested, in
each case addressed to the principal office of the Company, Attention:
President.

         SECTION 8. MISCELLANEOUS. This Agreement and any term hereof may be
changed, waived, discharged or terminated only by an instrument in writing
signed by both the Company and the Purchaser. This Agreement shall be construed
and enforced in accordance with, and governed by the laws of, the State of North
Carolina. This Agreement may be executed in one or more counterparts each of
which shall be deemed an original, but all of which together shall constitute
one and the same agreement. The headings in this Agreement are for purposes of
reference only, and shall not limit or otherwise affect any of the terms hereof.

         SECTION 9. COMPLIANCE WITH LAWS. The exercise by the Purchaser of its
rights hereunder shall be subject to compliance with applicable securities laws
(including without limitation Section 5 of the Securities Act of 1933, as
amended, as it relates to the integration of offerings) and the rules and
regulations of self-regulatory organizations (including without limitation, the
National Association of Securities Dealers, including those governing
underwriters' compensation, free writing and withholding). If, at the time of
the proposed exercise of any of the Purchaser's rights hereunder, the exercise
of such rights would violate any of such laws or regulations, the parties agree
to modify this Agreement and use their respective best efforts to preserve the
economic benefits provided by this Agreement, and the Company shall compensate
the Purchaser in such a way as to realize the benefit of its rights hereunder;
provided, however, that if the violation is based on the amount of the economic
benefit to be received, an appropriate adjustment in such amount shall be agreed
to by the parties.

         SECTION 10. PROTECTIVE PROVISION. The Company agrees to not permit any
entity which is controlled by the Company or by the Holding Company to
consummate an initial public offering of capital stock pursuant to the
Securities Act of 1933, as amended, without providing the Purchaser the option
to realize the benefit of its rights hereunder.
