                           WARRANTIES OF THE COMPANY

         The Company hereby represents and warrants to the Investors, and to
each of them, as follows:

         5.1      Corporate Existence and Power. The Company and each of its

                                      15
<PAGE>   21

         5.2      Corporate Authorization; No Contravention. The execution,
delivery and performance by the Company of this Agreement, the Registration
Rights Agreement and the transactions contemplated hereby and thereby,
including without limitation the issuance of the Preferred Shares, the Warrants
and the Common Stock issuable upon the conversion of the Preferred Shares and
exercise of the Warrants:

                  (a)      are within the Company's corporate power and
authority and have been duly authorized by all necessary corporate action; and

                  (b)      will not violate, conflict with or result in any
breach or contravention of or the creation of any Lien under, any Material
Contract of the Company or any of its Subsidiaries or any order or decree
directly relating to the Company or any of its Subsidiaries.

         5.3      Governmental Authorization; Third Party Consents. Except as
contemplated by Section 4.6 and certain consents from holders of registration
rights, no approval, consent, exemption, authorization, or other action by, or
notice to, or filing with, any Governmental Authority or any other Person, is
necessary or required in connection with the execution, delivery or performance
by the Company or enforcement against the Company of this Agreement, the
Preferred Shares, the Warrants, the Registration Rights Agreement or the
transactions contemplated hereby or thereby.

         5.4      Binding Effect. This Agreement has been duly executed and
delivered by the Company, and at the Initial Closing and each Additional
Closing, the Preferred Shares, the Warrants and the Registration Rights
Agreement will be duly executed or delivered, as applicable, by the Company.
This Agreement constitutes the legal, valid and binding obligation of the
Company enforceable against the Company in accordance with its terms, subject,
as to enforcement of remedies, to bankruptcy, insolvency, reorganization,
moratorium, fraudulent transfer, or similar laws affecting creditors' rights
generally from time to time in effect and general equitable principles, except
that any rights to indemnification set forth in this Agreement may be limited
by federal and state securities laws and public policy considerations. At the
Initial Closing and each Additional Closing, the Registration Rights Agreement,
the Warrants and the Preferred Shares will constitute the legal, valid and
binding obligations of the Company enforceable against the Company in
accordance with their respective terms, subject, as to enforcement of remedies,
to bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer, or
similar laws affecting creditors' rights generally from time to time in effect
and general equitable principles, except that any rights to indemnification set
forth in the Registration Rights Agreement may be limited by federal and state
securities laws and public policy considerations.

         5.5      No Legal Bar. Neither the execution, delivery or performance
of this Agreement or the Registration Rights Agreement nor the issuance or
performance



                                      16
<PAGE>   22

of the terms of the Preferred Shares or the Warrants will violate any
Requirement of Law or any rule or regulation of NASDAQ.

         5.6      Litigation.

                  (a)      Except as set forth on Schedule 5.6, there are no
actions, suits, proceedings, claims or disputes pending, or to the Knowledge of
the Company, threatened, at law, in equity, in arbitration or before any
Governmental Authority against the Company or any of its Subsidiaries:

                           (i)      with respect to this Agreement, the
Preferred Shares, the Warrants or the Registration Rights Agreement or any of
the transactions contemplated hereby or thereby; or

                           (ii)     which would, if adversely determined, (i)
have a material adverse effect on the Condition of the Company or (ii) have a
material adverse effect on the ability of the Company to perform its
obligations under this Agreement, the Preferred Shares, the Warrants or the
Registration Rights Agreement.

                  (b)      No injunction, writ, temporary restraining order,
decree or any order of any nature has been issued by any court or other
Governmental Authority purporting to enjoin or restrain the execution, delivery
and performance of this Agreement, the Preferred Shares, the Warrants or the
Registration Rights Agreement.

         5.7      No Default or Breach. No event has occurred and is continuing
which constitutes a default under or breach of any of the provisions of Article
8 or 9. No event which constitutes a default under or breach of any of the
provisions of Article 8 or 9 is likely to result from the incurring of
obligations by the Company under this Agreement, or the Registration Rights
Agreement or from the issuance of the Preferred Shares or the Warrants. Neither
the Company nor any of its Subsidiaries is in default under or with respect to
any Contractual Obligation in any respect, which, individually or together with
all such defaults, would have a material adverse effect on the Condition of the
Company or on the ability of the Company to perform its obligations under this
Agreement, the Preferred Shares, the Warrants or the Registration Rights
Agreement.

         5.8      Title to Properties. The Company and each of its Subsidiaries
have good and defensible title to, or hold leases in full force and effect in
all their real property, except for such defects in title as could not,
individually or in the aggregate, have a material adverse effect on the
Condition of the Company or the ability of the Company to perform its
obligations under this Agreement, the Preferred Shares, the Warrants or the
Registration Rights Agreement.

shown on said returns and on all assessments received by it to the extent that
such taxes have become due, except taxes the validity or amount of which is
being contested in good faith by appropriate proceedings and with respect to
which adequate reserves have been set aside. The Company and its Subsidiaries
have paid or caused to be paid, or have established reserves that the Company
reasonably believes to be adequate for all income tax liabilities applicable to

the Company as of the dates thereof and the consolidated results of operations
of the Company for the period, or portion thereof, then ended (except in the
case of the 2000 Interim Financials, for normal year-end adjustments and the
absence of footnotes).

         5.11     No Material Adverse Change. Since June 30, 2000, there has

respects with the requirements of its respective report form.

material adverse effect on the Condition of the Company; and, to the Knowledge
of the Company, there are no past or present events, conditions, circumstances,
activities, practices, incidents, agreements, actions or plans which could

controlling the Company is an "investment company" within the meaning of the
Investment Company Act of 1940, as amended.

         5.15     Subsidiaries. Schedule 5.15 sets forth a complete and
accurate list of all of the Subsidiaries of the Company together with their
respective jurisdictions of incorporation or organization. Each such Subsidiary
is directly or indirectly wholly owned by the Company.

                           property, to lease the property it operates as

                           currently, or is currently proposed to be, engaged.

         6.2      Authorization; No Contravention. The execution, delivery and
performance by each of the Investors of this Agreement, the Registration Rights
Agreement and the transactions contemplated hereby and thereby, including
without limitation the acquisition of the Preferred Shares, the Warrants and
the Common Stock issuable upon the conversion of the Preferred Shares and
exercise of the Warrants: (a) is within the Investor's power and authority and
has been duly authorized by all necessary action;

                  (b)      does not contravene the terms of the Investor's
governing documents, or any amendment thereof;

                  (c)      will not violate, conflict with or result in any
breach or contravention of or the creation of any Lien under, any Contractual
Obligation of the Investor, or any order or decree directly relating to the
Investor, and

                  (d)      does not require approval, consent, exemption,
authorization or other action by, or notice to, or filing with, any
Governmental Authority or any other Person, other than filing and expiration of

Closing Date, the Registration Rights Agreement will be duly executed and
delivered by each of the Investors, constitutes the legal, valid and binding

<PAGE>   31

enforceability may be limited by applicable bankruptcy, insolvency, or similar
laws affecting the enforcement of creditors' rights generally or by equitable
principles relating to enforceability.

         6.4      No Legal Bar. The execution, delivery and performance of this
Agreement and the Registration Rights Agreement will not violate any
Requirement of Law or any Contractual Obligation of any of the Investors.

         6.5      Purchase for Own Account. The Preferred Shares and the
Warrants (including, for purposes of this Section 6.5, the Common Shares
issuable upon conversion of the Preferred Shares and exercise of the Warrants)
to be acquired by each of the Investors pursuant to this Agreement are being
acquired for its own account for investment purposes and with no view toward
any "distribution" thereof within the meaning of the Securities Act, without
prejudice, however, to the rights of such Investors at all times to sell or
otherwise dispose of all or any part of the Preferred Shares or the Warrants
under an effective registration statement under the Securities Act, or under an
exemption from such registration available under the Securities Act, or
pursuant to Article 10 hereof, and subject, nevertheless, to the disposition of
the Investors' property being at all times within their control. If any of the
Investors should in the future decide to dispose of any of the Preferred
Shares, Warrants, the shares of Common Stock issuable upon conversion of the
Preferred Shares or the Warrant Shares, such Investor understands and agrees
that it may do so only in compliance with the Securities Act and applicable
state securities laws, as then in effect, and that stop-transfer instructions
to that effect, where applicable, will be in effect with respect to the
Preferred Shares. If any of the Investors should decide to dispose of the
Preferred Shares or Warrants, other than pursuant to the provisions of the
Registration Rights Agreement or Article 10 hereof, such Investor, if requested
by the Company, will have the obligation in connection with such disposition,
at the Investors's expense, of delivering to the Company an opinion of counsel
of recognized standing in securities law, to the effect that the proposed
disposition of the Preferred Shares or Warrants would not be in violation of
the Securities Act or any applicable state securities laws and, assuming such
opinion is required and is otherwise appropriate in form and substance under
the circumstances, the Company will accept, and will recommend to any
applicable transfer agent or trustee for any such securities that it accept,
such opinion. The Investors agree to the imprinting, so long as required by
law, of a legend on certificates representing all of the Preferred Shares and
the shares of Common Stock issued on conversion thereof to the following
effect:

         "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
         REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE "SECURITIES
         ACT") OR THE SECURITIES LAWS OF ANY STATE AND MAY NOT BE SOLD
         OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE
         REGISTRATION STATEMENT UNDER SUCH ACT AND APPLICABLE STATE
         SECURITIES LAWS OR AN



                                      26
<PAGE>   32


         APPLICABLE EXEMPTION TO THE REGISTRATION REQUIREMENTS OF SUCH ACT OR
         SUCH LAWS."

The Investors agree to the imprinting, so long as required by law, of a legend
on the Warrants and the Warrant Shares to the following effect:

         "THE WARRANT AND SHARES ISSUABLE UPON EXERCISE OF THIS
         WARRANT HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
         1933 (THE "SECURITIES ACT") OR QUALIFIED UNDER ANY STATE
         SECURITIES LAW. THE WARRANT AND SHARES ISSUABLE UPON EXERCISE
         OF THIS WARRANT MAY NOT BE SOLD, OFFERED FOR SALE,
         TRANSFERRED, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN
         EFFECTIVE REGISTRATION STATEMENT WITH RESPECT THERETO UNLESS
         SOLD, TRANSFERRED, PLEDGED OR HYPOTHECATED IN A TRANSACTION
         THAT IS EXEMPT FROM REGISTRATION UNDER THE SECURITIES ACT."

         6.6      Broker's, Finder's or Similar Fees. There are no brokerage
commissions, finder's fees or similar fees or commissions payable in connection
with the transactions contemplated hereby based on any agreement, arrangement
or understanding with the Investors or any action taken by the Investors.

         6.7      Investment Knowledge. Each Investor has sufficient knowledge
and experience in financial and business matters and the business in which the
Company is engaged so as to be capable of evaluating the merits and risks of
its investment in the Preferred Shares, Warrants, the shares of Common Stock
issuable upon conversion of the Preferred Shares and the Warrant Shares, and is
able to bear the economic risk of the loss of its investment in the Company.
Each of the Investors is an "accredited investor" within the meaning of Rule
501 promulgated under the Securities Act.


                                   ARTICLE 7

                                INDEMNIFICATION

         7.1      Indemnification by the Company. In addition to all other sums
due hereunder or provided for in this Agreement, the Company agrees to
indemnify and hold harmless the Investors and their Affiliates (including,
without limitation, Brown Brothers Harriman & Co.) and their respective
officers, directors, agents, employees, subsidiaries, partners and controlling
persons (each, an "Indemnified Party") to the fullest extent permitted by law
from and against any and all losses, claims, damages, expenses (including
reasonable fees, disbursements and other charges of counsel) or other
liabilities ("Liabilities") resulting from any breach of any covenant,
agreement, representation or warranty of the Company in this Agreement or any
legal,



                                      27
<PAGE>   33

administrative or other actions (including actions brought by the Company or
any equity holders of the Company or derivative actions brought by any Person
claiming through the Company or in the Company's name), proceedings or
investigations (whether formal or informal), or written threats thereof, based
upon, relating to or arising out of this Agreement, the Preferred Shares, the
Warrants, the Registration Rights Agreement, the transactions contemplated
hereby or thereby, or any indemnified person's role therein or in the
transactions contemplated hereby or thereby; provided, however, that the
Company shall not be liable under this Section 7.1: (a) for any amount paid in
settlement of claims without the Company's consent (which consent shall not be
unreasonably withheld), (b) with respect to Liabilities arising solely out of
actions brought by the partners or members of any of the Investors against an
Indemnified Party or by one Indemnified Party against another, (c) to the
extent that it is finally judicially determined that such Liabilities resulted
primarily from (i) the willful misconduct, bad faith or gross negligence of
such Indemnified Party or (ii) a breach of the Investor's representations in
Article 6 or any breach of the Investor's obligations under this Agreement or
the Registration Rights Agreement, or (d) any Liabilities arising solely from
the transfer of the Preferred Shares or the Warrants by any of the Investors to
any Person; provided, further, that if and to the extent that such
indemnification is unenforceable for any reason, the Company shall make the
maximum contribution to the payment and satisfaction of such indemnified
liability which shall be permissible under applicable laws. In connection with
the obligation of the Company to indemnify for expenses as set forth above, the
Company further agrees to reimburse each Indemnified Party for all such
expenses (including reasonable fees, disbursements and other charges of
counsel) as they are incurred by such Indemnified Party; provided, however,
that if an Indemnified Party is reimbursed hereunder for any expenses, such
reimbursement of expenses shall be refunded to the extent it is finally
judicially determined that the Liabilities in question resulted primarily from
the willful misconduct, bad faith or gross negligence of such Indemnified
Party. The maximum aggregate amount the Company shall be required to pay any
Investor under this section 7.1 with respect to Liabilities resulting from any
breach of any covenant, agreement, representation or warranty of the Company in
this Agreement shall not exceed the aggregate Purchase Price paid by such
Investor under this Agreement.

         7.2      Notification. Each Indemnified Party under this Article 7
will, promptly after the receipt of notice of the commencement of any action or
other proceeding against such Indemnified Party in respect of which indemnity
may be sought from the Company under this Article 7, notify the Company in
writing of the commencement thereof. The omission of any Indemnified Party so
to notify the Company of any such action shall not relieve the Company from any
liability which it may have to such Indemnified Party (i) other than pursuant
to this Article 7 or (ii) under this Article 7 unless, and only to the extent
that, such omission results in the Company's forfeiture of substantive rights
or defenses. In case any such action or other proceeding shall be brought
against any Indemnified Party and it shall promptly notify the Company of the
commencement thereof, the Company shall be entitled to



                                      28
<PAGE>   34

participate therein and, to the extent that it may wish, to assume the defense
thereof, with counsel reasonably satisfactory to such Indemnified Party;
provided, however, that any Indemnified Party may, at its own expense, retain
separate counsel to participate in such defense. Notwithstanding the foregoing,
in any action or proceeding in which both the Company and an Indemnified Party
is, or is reasonably likely to become, a party, such Indemnified Party shall
have the right to employ separate counsel at the Company's expense and to
control its own defense of such action or proceeding if, in the reasonable
opinion of counsel to such Indemnified Party, (a) there are or may be legal
defenses available to such Indemnified Party or to other indemnified parties
that are different from or additional to those available to the Company or (b)
any conflict or potential conflict exists between the Company and such
Indemnified Party that would make such separate representation advisable;
provided, however, that in no event shall the Company be required to pay
unreasonable fees or expenses or fees and expenses under this Section 7 for
more than one firm of attorneys in any jurisdiction in any one legal action or
group of related legal actions. The Company agrees that the Company will not,
without the prior written consent of the Investors, settle, compromise or
consent to the entry of any judgment in any pending or threatened claim, action
or proceeding relating to the matters contemplated hereby (if any Indemnified
Party is a party thereto or has been actually threatened to be made a party
thereto) unless such settlement, compromise or consent includes an
unconditional release of the Investors and each other Indemnified Party from
all liability arising or that may arise out of such claim, action or
proceeding. The rights accorded to indemnified parties hereunder shall be in
addition to any rights that any Indemnified Party may have at common law, by
separate agreement or otherwise.

         7.3      Registration Rights Agreement. Notwithstanding anything to
the contrary in this Article 7, the indemnification and contribution provisions
of the Registration Rights Agreement shall govern any claim made with respect
to registration statements filed pursuant thereto or sales made thereunder.

public accountants, all at such reasonable times during normal business hours
and as often as may be reasonably requested, upon reasonable advance notice to

                  (b)      The Investors and any Holder which is an Affiliate
of any of the Investors expressly agrees that any confidential information
relating to the Company and its Subsidiaries obtained (i) in negotiation and
execution of this Agreement, (ii) during any inspection pursuant to Section
8.9(a), (iii) pursuant to Section 8.1(c) or 8.10, (iv) from the Company or any
of its Subsidiaries or representatives thereof which is clearly marked
"Confidential" on the first or cover page thereof or (v) in conducting its due
diligence investigation of the Company prior to the execution of this

Investors and such Affiliate, and that they shall use their best efforts to
cause any person designated pursuant to Section 8.10 to attend meetings of the
Board of Directors to keep all Information confidential.

         The term "Information" shall not include any information which (i) at
the time of disclosure or thereafter is generally available to or known by the
public (other than as a result of its disclosure by the Investors or such
Affiliate), (ii) was available to the Investors or such Affiliate on a

         8.10     Board Representation.

                  (a)      The Company shall promptly cause two vacancies to be
created on its Board of Directors (by increasing the number of members of the
Board of Directors or otherwise) and at the Initial Closing shall cause two
persons designated by the Fund (unless, after customary investigation of such
persons' qualifications, the Board of Directors reasonably determines in good
faith that either or both of such persons is not qualified or acceptable under
standards applied fairly and equally to all nominees) to be selected to fill
such vacancies. One of the persons designated by the Fund may, at the Fund's
written election, be designated by an Additional Investor, but in no case shall
the Holders of Preferred Stock collectively designate more than two persons to
serve on the Board of Directors. Such designees shall serve until the next
succeeding annual meeting of stockholders of the Company to be held after such
election.

                  (b)      Commencing with such next succeeding annual meeting
of stockholders of the Company referred to in Section 8.10(a), (i) so long as
the Fund holds 50% of the shares of Preferred Stock or Common Stock issued or
issuable upon conversion of the Preferred Shares (whether or not the Preferred
Shares have been converted) acquired by it under this Agreement, the Fund shall
be entitled to designate two directors to the Company's Board of Directors (one
of whom at the Fund's written election may be designated by an Additional
Investor) or (ii) so long as the Fund holds 25% of the shares of Common Stock
issued or issuable upon conversion of the Preferred Shares (whether or not such
shares have been converted) acquired by it under this Agreement, the Fund shall
be entitled to designate one director to the Company's Board of Directors, and,
in either case, at relevant future annual meetings of the stockholders of the
Company, a successor to replace any such director upon expiration of his or her
term. The Company shall cause such designees (unless, after customary
investigation of any such person's qualifications, the Board of Directors
reasonably determines in good faith that such person is not qualified or
acceptable under standards applied fairly and equally to all nominees) to be
included in the slate of nominees recommended by the Board to the Company's
stockholders for election as directors, and the Company shall use its
reasonable best efforts to cause the election of such designees, including
voting all shares for which the Company holds proxies (unless otherwise
directed by the stockholder submitting such proxy) or is otherwise entitled to
vote, in favor of the election of such person. Notwithstanding the foregoing,
if the Fund has not designated a person pursuant to Section 8.10(a), or if the
Fund is entitled to designate a director or directors to the Company's Board of
Directors by virtue of the first sentence of this Section 8.10(b) and the Fund
does not designate at least one director to the Company's Board of Directors,
the Fund shall be entitled to receive all notices and materials distributed to
the members of the Board of Directors of the Company, and to designate one
person who shall be entitled to attend all meetings of the Board of Directors
and committees thereof and to receive minutes of all such meetings upon
preparation thereof.

<PAGE>   40

                  (c)      In the event any designee of the Fund (or at the
Fund's written election, by an Additional Investor) shall cease to serve as a
director for any reason, other than by reason of the Fund not being entitled to
designate a designee as provided in Section 8.10(a) or 8.10(b), the Company
shall use its reasonable best efforts to cause the vacancy resulting thereby to
be filled by a designee of the Fund (or at the Fund's written election, by an
Additional Investor).

         8.11     Registration and Listing. If any shares of Common Stock
required to be reserved for purposes of conversion of the Preferred Shares as
provided in the Certificate of Designation or for purposes of exercise of the
Warrants as provided therein require registration with or approval of any
Governmental Authority under any Federal or state or other applicable law
before such Common Stock may be issued or delivered upon such conversion or
exercise, the Company will endeavor in good faith and as expeditiously as
possible to cause such Common Stock to be duly registered or approved, as the
case may be, unless such registration or approval is required solely because of
a breach of the Investors' representation contained in Section 6.5. So long as
the Common Stock is quoted on the NASDAQ or listed on any national securities
exchange, the Company, if permitted by the rules of such system or exchange,
will quote or list and keep quoted or listed on such system or exchange, upon
official notice of issuance, all Common Stock issuable or deliverable upon
conversion of the Preferred Shares and exercise of the Warrants.

         8.12     Private Offering. In the event the Company proposes to sell
Common Stock in an offering not required to be registered under the Securities
Act, it will give the Investors at least 20 Business Days prior notice. If any
of the Investors elects by written notice to the Company within 15 Business
Days after receipt of such notice, it may participate in the sale (under the
same terms and conditions as set out in such offering), by including in such
sale in place of an equal number of shares of Common Stock to be sold by the
Company, such aggregate number of shares of Common Stock as is equal to the
product obtained by multiplying (i) the number of shares of Common Stock
proposed to be sold by the Company by (ii) a fraction (A) the numerator of
which is the number of shares of Common Stock into which the Preferred Shares
held by such Investor have heretofore been or may be converted and (B) the
denominator of which is the sum of (x) the amount of such numerator and (y) the
total number of shares of Common Stock outstanding at such time. The provisions
of this Section 8.12 shall not apply to issuances of Common Stock in connection
with: (1) acquisitions by the Company, (2) the exercise of options or
conversion of convertible securities and (3) services rendered to the Company.

         8.13     Additional Registration Rights. The Company shall not provide
any registration rights with respect to its securities which are superior or
inconsistent with those granted under the Registration Rights Agreement.

                               NEGATIVE COVENANTS

         The Company hereby covenants and agrees with the Investors, any
Affiliate of the Investors, and any Holder so long as such Person holds any
Preferred Shares or Warrants, that without the prior consent of such Person in
accordance with Section 11.4:

         9.1      Consolidations and Mergers. The Company shall not merge,
consolidate with or into, or convey, transfer, lease or otherwise dispose of
(whether in one transaction or in a series of transactions) all or
substantially all of its assets (whenever acquired), except the Company may
consolidate or merge with or into, or sell all or substantially all of its
assets to, any Person if:

                  (a)      The corporation or partnership formed by such
consolidation or surviving such merger or the Person which acquires all or
substantially all of the assets of the Company shall be (after giving effect to
such transaction) a Solvent corporation or partnership organized or formed, as
the case may be, and existing under, the laws of the United States, any state
thereof, or the District of Columbia and shall expressly assume in writing all
of the obligations of the Company under this Agreement, the Preferred Shares,
the Warrants and the Registration Rights Agreement;

                  (b)      immediately after giving effect to such transaction,
no default under, or breach of, provisions of Article 8 and 9 exists; and

                  (c)      the Company shall have furnished to the Holders (i)
an opinion of counsel satisfactory to a majority in interest of the Holders
addressing the matters (other than Solvency) set forth in clause (a) above and
(ii) the certificate of the Chief Financial Officer of the Company to the
effect that such transaction has been consummated in compliance with the
foregoing requirements; provided that nothing in this Section 9.1 shall affect
the rights of any Holder under this Agreement, the Preferred Shares, the
Warrants or the Registration Rights Agreement.

         9.2      Transactions with Affiliates. The Company shall not, and
shall not permit any of its Subsidiaries to, enter into any transaction with
any Affiliate of the Company or of any such Subsidiary, except on terms no less
favorable to the Company or such Subsidiary than those the Company or such
Subsidiary would obtain in a comparable arm's-length transaction with a Person
not an Affiliate of the Company or such subsidiary; provided that any
transaction approved by a majority of the independent directors of the Company
shall be conclusively deemed to be on such terms.

         9.3      No Inconsistent Agreements. Neither the Company nor any of
its Subsidiaries shall enter into any loan or other agreement, or enter into
any amendment



                                      36
<PAGE>   42

or other modification to any currently existing agreement, which by its terms
restricts or prohibits the ability of the Company to pay dividends on the
Preferred Stock, to issue Common Stock upon conversion of the Preferred Stock
in accordance with the Certificate of Designation and this Agreement or to
issue the Warrant Shares; provided, however, that the foregoing shall not
prevent the Company from entering into loan or other agreements that contain
restrictions on the ability of the company to pay dividends on the Preferred
Stock either (i) during the existence of an event of default under such
agreements or (ii) if such payment or repurchase would, although not in itself
a breach of any covenant in any such agreement, result in the occurrence of a
default or event of default arising from a breach by the Company of one or more
covenants regarding the financial condition of the Company so long as, on the
date such agreement is entered into, (x) the terms of any such covenants would
not prohibit such payment on such date and (y) the Company does not reasonably
anticipate that any of the terms of such covenants is likely to be breached
during the term of such agreement as a result of such payment of dividend.

         9.4      Issuance of Preferred Stock. The Company shall not issue any
Preferred Stock except pursuant to this Agreement.


                                   ARTICLE 10

                                  DISPOSITIONS

         10.1     Dispositions by Smith.

                  (a)      If D. Gregory Smith ("Smith") at any time or from
time to time proposes or agrees to sell or transfer to a Person or a "group"
(within the meaning of Section 13(d)(3) of the Exchange Act) of Persons, any
shares of Common Stock held by him, and so long as the Fund and all Holders
that are Affiliates of the Fund hold collectively at least five percent of the
Common Stock issued or issuable upon conversion of the Preferred Stock, Smith
shall give written notice of such proposed sale to the Fund within 15 Business
Days prior to the date of such sale, which notice shall state the price and
other terms of the proposed transaction and shall state the number of shares
proposed to be sold; provided, however, that the provisions of this Section
10.1(a) shall not apply to the sale or transfer of any shares of Common Stock
held by Smith unless the sum of such shares plus all other shares of Common
Stock sold or transferred by Smith during the period from the Closing Date to
the date of the proposed sale or transfer of such share shall be equal to or
greater than 25% of the number of shares of Common Stock held by Smith on the
date hereof (assuming the exercise of all options held by Smith). So long as
the Fund and all Holders that are Affiliates of the Fund hold collectively at
least five percent of the Common Stock issued or issuable upon conversion of
the Preferred Stock, the Fund and each such Holder may, upon giving written
notice thereof to Smith within ten Business Days after receipt of the notice
provided for in the first sentence of this Section 10.1, participate



                                      37
<PAGE>   43

in such sale on the same terms and conditions as those offered by Smith to such
third party or parties, by including in such sale in place of an equal number
of shares of Common Stock held by Smith (excluding any shares with respect to
which the provisions of this Section 10.1(a) shall not apply in accordance with
the preceding sentence hereof) such aggregate number of shares of Common Stock
as is equal to the product obtained by multiplying (i) the number of shares of
Common Stock proposed to by sold by Smith by (ii) a fraction (A) the numerator
of which is the number of shares of Common Stock into which the Preferred
Shares held by the Fund and each such Holder have theretofore been converted or
may be converted and (B) the denominator of which is the sum of (x) the amount
of such numerator and (y) 7,345,800 (which number shall be adjusted
appropriately for any subdivision, combination, reclassification or similar
event with respect to the Common Stock).

                  (b)      Notwithstanding anything to the contrary in this
Agreement, including Section 10.1(a) hereof, the provisions of this Section
10.1 shall not apply to any sale or transfer by Smith of any shares of Common
Stock (i) to (A) a spouse, (B) any of his lineal descendants, (C) a partnership
or trust set up for the benefit of one or more of such persons or (D) any
entity controlled by Smith; provided, however, that any proposed sale or
transfer by any of such transferees shall be deemed to be a sale or transfer by
Smith for purposes of this Section 10.1, or (ii) pursuant to a transaction
intended to be a charitable contribution.

                  (c)      The provisions of this Section 10.1 shall terminate
upon the death or disability of Smith or if Smith is no longer either an
officer or director of the Company. The term "disability" shall mean, with
respect to Smith, that due to physical or mental infirmity, whether total or
partial, Smith is permanently unable to perform his usual duties for the
Company.

         10.2     Dispositions by the Fund.

                  (a)      Except as set forth below, until the earlier to
occur of (i) the first anniversary of the Closing Date, (ii) the date on which
the Fund and all Holders that are Affiliates of the Fund collectively cease to
own at least five percent of the Common Stock issued or issuable upon
conversion of the Preferred Stock, (iii) the occurrence of a Change of Control
and (iv) the occurrence of a breach with respect to any of the covenants set
forth in Sections 8.8, 8.9, 8.10, 8.11, 8.12 and 8.13 or Article 9, which
breach remains uncured ten Business Days after written notice is provided to
the Company (the "Transfer Restriction Period"), the Fund shall not transfer or
sell any derivative security with respect to or otherwise dispose of its Common
Stock, Preferred Shares or Warrants.

                  (b)      Notwithstanding anything in this Section 10.2 to the
contrary, the Fund may, at any time and from time to time, sell or otherwise
transfer Common Stock or Preferred Shares (i) pursuant to an exchange offer or
a tender offer



                                      38

not opposed by a majority of the Company's Board of Directors, (ii) pursuant to
any all cash tender offer made by any Person for all of the issued and
outstanding Common Stock, (iii) pursuant to the Registration Rights Agreement,
(iv) to any of the Fund's Affiliates, or (v) to the Fund's limited partners
pursuant to a pro rata distribution; provided, however, that any Affiliates (or
limited partners) of the Fund to which such securities are transferred shall
agree to be bound by all of the transfer restrictions set forth in this Section
10.2.

                  (c)      Except as otherwise provided in Section 10.2(b), any
securities transferred by the Fund shall not thereafter be subject to the
provisions of this Section 10.2.
