                        AND PROPRIETARY RIGHTS AGREEMENT

         THIS EMPLOYMENT, NON-COMPETITION AND PROPRIETARY RIGHTS AGREEMENT (the
"Agreement") is made as of this 26th day of April, 2004, by and between CAPITAL
GROWTH SYSTEMS, INC., a Florida corporation (the "Company"), and RORY HERRIMAN
(the "Employee").

                                    RECITALS:

         A. The Company is the parent of Nexvu Technologies, L.L.C., a Delaware
limited liability company (the "Subsidiary") in the business of providing
products and software solutions to the networked computer industry;

         B. The Company desires to employ the Employee and Employee desires to
be employed by the Company to serve as the Chief Operating Officer and Chief
Technology Officer of the Company and the Subsidiary; and

         C. It is contemplated that in such capacity, Employee shall provide
services for the Company and for the Subsidiary.

         NOW, THEREFORE, in consideration of the foregoing and the agreements,
covenants and conditions set forth herein, the Employee and the Company hereby
agree as follows:

                                    ARTICLE I

                                   EMPLOYMENT

         Section 1.1 Employment. The Company hereby employs, engages and hires
Employee, and Employee hereby accepts employment, upon the terms and conditions
set forth in this Agreement. The Employee shall constitute an employee of the
Company, but shall provide services to both the Company and its Subsidiary.
During the term of this Agreement, Employee shall hold the title of Chief
Operating Officer and Chief Technology Officer of the Company and of the
Subsidiary. The Employee shall have and fully perform the duties and
responsibilities as may be, from time to time, specified by the Company's
President or its Board of Directors. The Employee shall report to the Chief
Executive Officer of the Company and to its Board of Directors.

         Section 1.2 Activities and Duties During Employment. Employee
represents and warrants to the Company that Employee is free to accept
employment with the Company and that Employee has no prior or other commitments
or obligations of any kind to anyone else which would hinder or interfere with
the acceptance and performance of the obligations under this Agreement.

         Employee accepts the employment described in Article 1 of this
Agreement and agrees to devote his exclusive full time and efforts to the
faithful and diligent performance of the services

<PAGE>

described herein, including the performance of such other services and
responsibilities as the Company may, from time to time, stipulate.
Notwithstanding the foregoing, Employee may: (i) serve on the board of directors
of other entities or serve in any capacity with any hobby, avocation, civic,
educational, professional or charitable organization provided that such service
does not materially interfere or conflict with his duties hereunder; and (ii)
make and manage personal investments of his choice.

                                   ARTICLE II

                                      TERM

         Section 2.1 Term. The term of employment under this Agreement shall be
for the period from the date first set forth above until December 31, 2004 (such
term of employment, as it may be extended or terminated, is herein referred to
as the "Employment Term"). The Employment Term shall automatically renew for
additional one (1) year periods unless terminated by Employee or the Company by
written notice not less than two (2) months prior to expiration of the
then-current term.

         Section 2.2 Termination. The Employment Term and employment of Employee
may be terminated as follows:

                  (a) Automatically, without the action of either party, upon
         the death of Employee.

                  (b) By either party upon the Total Disability of the Employee.
         The Employee shall be considered to have a Total Disability for
         purposes of this Agreement if he is unable by reason of accident or
         illness to substantially perform his employment duties, and is expected
         to be in such condition for periods totaling three (3) months (whether
         or not consecutive) during any period of twelve (12) consecutive
         months. The determination of whether a Total Disability has occurred
         shall be based on the determination of a physician selected by the
         Company. Nothing herein shall limit the Employee's right to receive any
         payments to which Employee may be entitled under any disability or
         employee benefit plan of the Company or under any disability or
         insurance policy or plan. During a period of Total Disability prior to
         termination hereunder, Employee shall continue to receive his full
         compensation (including base salary and bonus) and benefits.

                  (c) By the Employee upon thirty (30) days' written notice to
         the Company.

                  (d) By Company "Without Cause," which shall mean a termination
         of the Employee's employment by the Company other than pursuant to the
         provisions of Section 2.2(a), Section 2.2(b) or Section 2.2(e) hereof.

                  (e) By the Company "With Cause," which shall mean termination
         of Employee's employment due to: (i) a breach of this Agreement by
         Employee; (ii) commission of an act of dishonesty, malfeasance, fraud
         or willful misconduct; (iii) failure to use good faith efforts to
         perform any duties assigned to Employee by the Company; or (iv)
         violation of any law (as determined in the good faith judgment of the
         Company).

<PAGE>

         Section 2.3 Cessation of Rights and Obligations: Survival of Certain
Provisions. On the date of expiration or earlier termination of the Employment
Term for any reason, all of the respective rights, duties, obligations and
covenants of the parties, as set forth herein, shall, except as specifically
provided herein to the contrary, cease and become of no further force or effect
as of the date of said termination, and shall only survive as expressly provided
for herein.

         Section 2.4 Cessation of Compensation. In lieu of any severance under
any severance plan that the Company may then have in effect, and subject to (i)
the receipt of a full and unconditional release from Employee and (ii) any
amounts owed by the Employee to the Company under any contract, agreement or
loan document entered into after the date hereof (including, but not limited to,
loans made by the Company to the Employee), the Company shall pay to the
Employee, and the Employee shall be entitled to receive, the following amounts
within thirty (30) days of the date of a termination of his employment:

                  (a) Voluntary Termination/Cause/Expiration of Term. Upon (i)
         termination of the Employee's employment pursuant to Section 2.2(c) or
         Section 2.2(e); or (ii) the expiration of the Employment Term because
         either party elects not to extend the Employment Term; the Employee
         shall be entitled to receive his base salary, any incentive
         compensation (earned to date of termination) and expense reimbursements
         solely through the date of termination.

                  (b) Death or Total Disability. Upon the termination of the
         Employment Term by reason of the death or Total Disability of the
         Employee, or pursuant to Section 2.2(d) the Employee (or, in the case
         of death, his estate) shall be entitled to receive in a lump sum his
         base salary through the date of death plus ninety (90) days, or
         determination of Total Disability plus ninety (90) days (which shall
         include any of his unused vacation pay for the year of such
         termination), unpaid bonus (if any, to the extent express provision has
         been made for a bonus) and expense reimbursement through the date of
         death or Total Disability.

                  (c) Failure to Renew/Termination Without Cause. Upon
         termination of Employee's employment pursuant to Section 2.2(d) or upon
         termination of Employee's employment due to the Company's delivery of
         written notice that it elects not to extend the Employment Term for an
         additional one-year period, then Executive shall be entitled to
         receive:

                           (i) payment of his base salary over a period of one
                  (1) year from the date of termination of employment, payable
                  in the same increments (e.g., semi-monthly if that is the
                  common payroll practice) as was the practice prior to
                  termination of employment; plus

                           (ii) any incentive compensation earned by Employee
                  through the date of termination of his employment.

         Section 2.5 Business Expenses.

                  (a) Reimbursement. The Company shall reimburse the Employee
         for all reasonable, ordinary, and necessary business expenses incurred
         by him in connection

<PAGE>

         with the performance of his duties hereunder, including, but not
         limited to, ordinary and necessary travel, lodging and dining expenses
         and entertainment expenses. The reimbursement of business expenses will
         be governed by the policies for the Company and the terms otherwise set
         forth herein.

                  (b) Accounting. The Employee shall provide the Company with an
         accounting of his expenses, which accounting shall clearly reflect
         which expenses were incurred for proper business purposes in accordance
         with the policies adopted by the Company and as such are reimbursable
         by the Company. The Employee shall provide the Company with such other
         supporting documentation and other substantiation of reimbursable
         expenses as will conform to Internal Revenue Service or other
         requirements. All such reimbursements shall be payable by the Company
         to the Employee within a reasonable time after receipt by the Company
         of appropriate documentation therefore.

                                   ARTICLE III

                            COMPENSATION AND BENEFITS

         Section 3.1 Compensation. During Employee's employment, the Company
shall pay Employee a base salary of $175,000 per annum, subject to increase in
the sole discretion of the Company. The Employee shall be eligible to earn a
bonus with respect to each calendar year in which Employee is employed (prorated
for factual years) of up to fifty percent (50%) of Employee's base salary upon
attainment by the Company and/or Employee of such objectives (subject to such
weighting and other factors as appropriate) as established by the Board of
Directors after consultation with Employee with respect to each calendar year.
The Company shall use its good faith efforts to establish such objectives no
later than March 31st of each year during the Employment Term, and to deliver a
copy of the same to Employee.

         Section 3.2 Payment. All compensation shall be payable in intervals in
accordance with the general payroll payment practice of the Company. The
compensation shall be subject to such withholdings and deductions by the Company
as are required by law.

         Section 3.3 Vacation. The Employee shall be entitled to up to four (4)
weeks' paid vacation per year (prorated for partial years). Two (2) weeks in the
aggregate of vacation shall carry over to subsequent years (no cash in lieu of
vacation not taken), and all vacation not taken in excess of two (2) weeks shall
lapse (i.e., in no event can cumulative rollover exceed two (2) weeks).

         Section 3.4 Options and Other Payments. The Company has awarded to
Employee effective as of the date of execution hereof an option (the "Option")
to purchase up to 430,000 shares of Common Stock in the form attached hereto as
Exhibit A.

         Section 3.5 Other Benefits. Employee shall be entitled to participate
in any retirement, pension, profit-sharing, stock option, health plan,
insurance, disability income, incentive compensation and welfare or any other
benefit plan or plans of the Company which may now or hereafter be in effect and
for which the Employee is eligible or for which all senior executives in general
are eligible. Notwithstanding the forgoing, the Company shall be under no

<PAGE>

obligation to institute or continue the existence of any such benefit plan.
Commencing no later than April 30, 2004, and continuing throughout the
Employment Term, the Company shall maintain directors' and officers' liability
insurance with aggregate coverage of not less than $1,000,000.

         Section 3.6 Bonus. If during the Employment Term Employee is employed
by the Company and the Company enters into a contract (the "Sale Contract"):

                  (a) for the sale of all or substantially all of its assets; or

                  (b) to be merged into another larger company (or that
         company's subsidiary - collectively, the "Acquirer") pursuant to which
         the shareholders of the Company receive capital stock of the Acquirer,
         and the Sale Contract closing is effected within one hundred eighty
         (180) days thereafter for an aggregate net consideration received by
         the Company's shareholders as a result of such transaction and after
         deduction of all associated transaction expenses (the "Net
         Consideration") (whether in cash or in kind, based upon a valuation as
         of the closing date as determined by the Company's Board of Directors
         in good faith), exceeds two (2) times the "Base Amount." The Base
         Amount will be the sum of:

                           (i) aggregate capital contributions made to the
                  Company and its subsidiaries; plus

                           (ii) the amount of consideration paid by the Company
                  for any acquisition made by it or any of its subsidiaries from
                  time to time (with non-cash consideration valued in good faith
                  discretion of the Board of Directors),

         then Employee shall be entitled to a bonus ("Sale Bonus") payable no
         later than ten (10) days following the closing of the Sale Contract
         equal to the lesser of 299% of Employee's base salary as of the date of
         such Sale Contract or the "Sale Bonus Amount" as set forth below. If
         the sale or merger is not consummated, then the Sale Bonus shall not be
         payable.

         The Sale Bonus Amount shall be an amount equal to the product of 1%
multiplied by the "Difference". The "Difference" will be the amount or value
which the shareholders of the Company receive on the day of closing of the Sale
Contract (measured as of the close of business on that day) in excess of the
"Product." The "Product" will be the number of shares of the Company's common
stock issued and outstanding on the closing date (in computing common stock,
any-in-the-money stock options, warrants, rights or other securities convertible
into common stock shall be deemed to constitute common stock on an as converted
basis), multiplied by the "Original Issue Price." The Original Issue Price is
the highest per share price at which the Company's common stock is sold by the
Company (as adjusted for stock splits, reverse splits, etc.) in a tranche of not
less than $100,000 of funding. For example, if on December 31, 2004 the Company
is merged into Company X for stock valued on that date of $100,000,000 and on
that date there were 20,000,000 shares of common stock outstanding and 2,000,000
in-the-money options, and the Original Issue Price was $2.00, then for purposes
of the bonus

<PAGE>

computation, the Difference would be $100,000,000 minus $60,000,000 or
$40,000,000, and the Sale Bonus would therefore be $400,000.

         The good faith determination of the Sale Bonus amount by the Company's
Board of Directors shall be binding on Employee absent manifest error; provided,
further, that the Sale Bonus shall not be payable to Employee in the event that
the Acquirer desires that Employee serve as an employee of the Acquirer for a
total annual compensation package no less than Employee's then existing total
annual compensation package and Employee refuses to enter into an employment
agreement with the Acquirer containing such provision.

         Section 3.7 Section 280G Covenant. The parties hereby agree that the
Company shall not be required to pay Employee any amount that would be an
"excess parachute payment" within the meaning of Section 280G of the Internal
Revenue Code of 1986, as amended (the "Code"), and payments otherwise required
under this Agreement shall be reduced, if necessary to prevent any such
payments. The prior sentence shall be interpreted consistent with the purpose of
avoiding the disallowance of deduction to the Company pursuant to Section
280G(a) of the Code.

                                   ARTICLE IV

                 CONFIDENTIALITY, NON-SOLICITATION, NON-COMPETE
                            AND QUIT CLAIM AGREEMENT

         Section 4.1 Non-Disclosure of Confidential Information. Employee hereby
acknowledges and agrees that the duties and services to be performed by Employee
under this Agreement are special and unique and that as of a result of the
employment hereunder, Employee will acquire, develop and use information of a
special and unique nature and value that is not generally known to the public or
to the Company's industry, including but not limited to, certain records, phone
locations, documentation, software programs, price lists, customer lists,
contract prices for the Company's services, business plans and prospects of the
Company, equipment configurations, ledgers and general information, employee
records, mailing lists, accounts receivable and payable ledgers, financial and
other records of the Company or its affiliates, and other similar matters (all
such information being hereinafter referred to as "Confidential Information").
Employee further acknowledges and agrees that the Confidential Information is of
great value to the Company and its affiliates and that the restrictions and
agreements contained in this Agreement are reasonably necessary to protect the
Confidential Information and the goodwill of the Company. Accordingly, Employee
hereby agrees that:

                  (a) Employee will not, while employed by the Company or for
         four (4) years thereafter, directly or indirectly, except in connection
         with Employee's performance of the duties under this Agreement, or as
         otherwise authorized in writing by the Company for the benefit of the
         Company, divulge to any person, firm, corporation, limited liability
         company, or organization, other than the Company (hereinafter referred
         to as "Third Parties"), or use or cause or authorize any Third Parties
         to use, the Confidential Information, except as required by law; and

<PAGE>

                  (b) Upon the termination of Employee's employment for any
         reason whatsoever, Employee shall deliver or cause to be delivered to
         the Company any and all Confidential Information, including drawings,
         notebooks, notes, records, keys, disks data and other documents and
         materials belonging to the Company which is in his possession or under
         his control relating to the Company, regardless of the medium upon
         which it is stored, and will deliver to the Company upon such
         termination of employment any other property of the Company which is in
         his possession or control.

         Section 4.2 Non-Solicitation Covenant. Employee hereby covenants and
agrees that while employed by the Company and for a period of two (2) years
following the termination of Employee's employment with the Company for any
reason, Employee shall not (i) directly or indirectly, contact, solicit,
interfere with, or entice away from the Company any person, firm, corporation,
limited liability company or other entity that was a customer of the Company at
any time while Employee was an employee of the Company or who is a "prospective
vendor or customer" of the Company, or (ii) induce or attempt to induce any
employee (or any person who was an employee during the year preceding the date
of any solicitation) of the Company to leave the employ of the Company, or in
any way interfere with the relationship between any such employee and the
Company. For purposes hereof, "prospective vendor or customer" shall mean any
person or entity which has been solicited for business by Employee or any
officer or other employee of the Company or its Affiliates at any time during
Employee's employment.

         Section 4.3 Non-Competition Covenant. Employee acknowledges that the
covenants set forth in this Section 4.3 are reasonable in scope and essential to
the preservation of the Business of the Company (as defined herein). Employee
also acknowledges that the enforcement of the covenants set forth in this
Section 4.3 will not preclude Employee from being gainfully employed in such
manner and to the extent as to provide a standard of living for himself, the
members of his family and the others dependent upon him of at least the level to
which he and they have become accustomed and may expect. In addition, Employee
acknowledges that the Company has obtained an advantage over its competitors as
a result of its name, location and reputation that is characterized by near
permanent relationships with vendors, customers, principals and other contacts
which it has developed at great expense. Furthermore, Employee acknowledges that
competition by him following the termination or expiration of his employment
would impair the operation of the Company beyond that which would arise from the
competition of an unrelated third party with similar skills. Employee hereby
agrees that he shall not, during his employment and for a period of one (1) year
after the end of his employment, directly or indirectly, engage in or become
directly or indirectly interested in any proprietorship, partnership, firm,
trust, company, limited liability company or other entity, other than the
Company (whether as owner, partner, trustee, beneficiary, stockholder, member,
officer, director, employee, independent contractor, agent, servant, consultant,
manager, lessor, lessee or otherwise) that:

                  (a) competes with the Company in the Business of the Company;
         or

                  (b) competes at a material level with the Company in the
         Restricted Territory (as defined herein), other than acquiring an
         ownership interest in a company listed on a recognized stock exchange
         in an amount which does not exceed five percent (5%) of the outstanding
         stock of such corporation. For purposes of this Agreement:

<PAGE>

                           (i) the term "Business of the Company" shall include
                  all business activities and ventures related to the business
                  of providing of any of the following:

                                    (A) provision of application performance
                           management tools, software, equipment or consulting
                           services related to application performance
                           management; or

                                    (B) solutions to the call center business in
                           a manner competitive with the activities of the
                           Company at any time during the term of Employee's
                           employment or expressly contemplated during the term
                           of Employee's employment with the Company; or

                                    (C) all other businesses in which the
                           Company is engaged in as of the date of termination
                           of Employee's employment; and

                           (ii) the term "Restricted Territory" means any state
                  in the United States of America. The Employee specifically
                  acknowledges that the Business of the Company is not naturally
                  restricted by any geographic boundaries.

         Section 4.4 Remedies.

                  (a) Injunctive Relief. Employee expressly acknowledges and
         agrees that the Business of the Company is highly competitive and that
         a violation of any of the provisions of Sections 4.1, 4.2 or 4.3 would
         cause immediate and irreparable harm, loss and damage to the Company
         not adequately compensable by a monetary award. Employee further
         acknowledges and agrees that the time periods and territorial areas
         provided for herein are the minimum necessary to adequately protect the
         Business of the Company, the enjoyment of the Confidential Information
         and the goodwill of the Company. Without limiting any of the other
         remedies available to the Company at law or in equity, or the Company's
         right or ability to collect money damages, Employee agrees that any
         actual or threatened violation of any of the provisions of Sections
         4.1, 4.2 or 4.3 may be immediately restrained or enjoined by any court
         of competent jurisdiction, and that a temporary restraining order or
         emergency, preliminary or final injunction may be issued in any court
         of competent jurisdiction, without notice and without bond.
         Notwithstanding anything to the contrary contained in this Agreement,
         the provisions of this Article IV shall survive the termination of
         Employee's employment.

                  (b) Enforcement. It is the desire of the parties that the
         provisions of Sections 4.1, 4.2 or 4.3 be enforced to the fullest
         extent permissible under the laws and public policies in each
         jurisdiction in which enforcement might be sought. Accordingly, if any
         particular portion of Sections 4.1, 4.2 or 4.3 shall ever be

enter into an Employment Agreement and to effect the undertakings set forth

the entire agreement and understanding of the parties hereto, and supersedes all
prior agreements and understandings relating to the subject matter hereof.
Except as provided in Section 4.4(b) above, no modification, amendment, waiver
or alteration of this Agreement or any provision or term hereof shall in any
event be effective unless the same shall be in writing, executed by both parties
hereto, and any waiver so given shall be effective only in the specific instance
and for the specific purpose for which given. The obligations of the parties
under this Agreement shall survive any termination of this Agreement.

agree, and it is their desire, that the court shall substitute a judicially
enforceable limitation in its place, and that as so modified the covenant shall
be binding upon the parties as if originally set forth herein.

         are authorized by the Company's articles of incorporation but not
         outstanding or reserved for issuance for purposes other than upon
         exercise of the Rights are not sufficient to permit the exercise in
         full of the Rights in accordance with the foregoing subparagraph (ii)
         of this Section 11(a), the Company, acting by resolution of a majority
         of the Board of Directors, shall (A) determine the value of the

         Common Stock or other equity securities of the Company (including,
         without limitation, shares, or units of shares, of preferred stock,

         or (6) any combination of the foregoing, having an aggregate value

         Purchase Price), where such aggregate value has been determined by the
         Board based upon the advice of a nationally recognized investment
         banking firm selected by the Board; provided, however, that if the
         Company shall not have made adequate provision to deliver value
         pursuant to clause (B) above within thirty (30) days following the
         later of (x) the first occurrence of a Section 11(a)(ii) Event and (y)

         23(a) expires (the later of (x) and (y) being referred to herein as the
         "Section 11(a)(ii) Trigger Date"), then the Company shall be obligated
         to deliver, upon the surrender for exercise of a Right and without
         requiring payment of the Purchase Price, shares of Common Stock (to the
         extent available) and then, if necessary, cash, which shares and/or

         Acquisition Date (or, if the Stock Acquisition Date shall have occurred
         prior to the Record Date, the close of business on the tenth day
         following the Record Date), or (ii) the Final Expiration Date, redeem
         all but not less than all of the then outstanding Rights at a

         adjusted to reflect any stock split, stock dividend or similar
         transaction

         Company so directs, supplement or amend any provision of this Agreement
         without the approval of any holders of certificates representing shares
         of Common Stock. From and after the Distribution Date and subject to
         the penultimate sentence of this Section 27, the Company may by
         resolution of a majority of the Board of Directors and the Rights Agent
         shall, if the Company so directs, supplement or amend this Agreement
         without the approval of any holders of Rights Certificates in order (i)
         to cure any ambiguity, (ii) to correct or supplement any provision
         contained herein which may be defective or inconsistent with any other
         provisions herein, (iii) to shorten or lengthen any time period
         hereunder, or (iv) to change or supplement the provisions hereunder in
         any manner which the Company may deem necessary or desirable and which,
         in the case of this clause (iv), shall not adversely affect the
         interests of the holders of Rights Certificates (other than an
         Acquiring Person or an Affiliate or Associate of an Acquiring Person);
         provided, however, that this Agreement may not be supplemented or
         amended to lengthen, pursuant to clause (iii) of this sentence, (A) a
         time period relating to when the Rights may be redeemed at such time as
         the Rights are not then redeemable, or (B) any other time period unless
         such lengthening is for the purpose of protecting, enhancing or
         clarifying the rights of, and/or the benefits to, the holders of
         Rights."

         9. Amendments to Section 29. Section 29 of the Rights Agreement is
hereby amended and restated in its entirety as follows:

                  "For all purposes of this Agreement, any calculation of the
         number of shares of Common Stock outstanding at any particular time,
         including for purposes of determining the particular percentage of such
         outstanding shares of Common Stock of which any Person is the
         Beneficial Owner, shall be made in accordance with the last sentence of
         Rule 13d-3(d)(1)(i) of the General Rules and Regulations under the
         Exchange Act. The Board of Directors of the Company shall have the
         exclusive power and authority to administer this Agreement and to
         exercise all rights and powers specifically granted to the Board or to
         the Company, or as may be necessary or advisable in the administration
         of this Agreement, including, without limitation, the right and power
         to (i) interpret the provisions of this Agreement, and (ii) make all
         determinations deemed necessary or advisable for the administration of
         this Agreement (including a determination to redeem or not redeem the
         Rights or to amend the Agreement). All such actions, calculations,
         interpretations and determinations (including, for purposes of clause
         (y) below, all omissions with respect to the foregoing) which are done
         or made by the Board of Directors in good faith, shall (x) be final,
         conclusive and binding on the Company, the Rights Agent, the holders of
         the Rights and all other parties, and (y) not subject the Board of
         Directors to any liability to the holders of the Rights."

         10. Amendments to Section 31. Section 31 of the Rights Agreement is
hereby amended and restated in its entirety as follows:

                  "If any term, provision, covenant or restriction of this
         Agreement is held by a court of competent jurisdiction or other
         authority to be invalid, void or unenforceable, the remainder of the
         terms, provisions, covenants and restrictions of this Agreement shall
         remain in full force and effect and shall in no way be affected,
         impaired or invalidated; provided, however, that notwithstanding
         anything in this Agreement to the contrary, if any such term,
         provision, covenant or restriction is held by such court or authority
         to be invalid, void or unenforceable and the Board of Directors of the
         Company determines in its good faith judgment that severing the invalid
         language from this Agreement would adversely affect the purpose or
         effect of this Agreement, the right of redemption set forth in Section
         23 hereof shall be reinstated and shall not expire until the close of
         business on the tenth day following the date of such determination by
         the Board of Directors."

that any additional notice be provided to it pertaining to the matters covered
by this Agreement.

of which shall be an original, but such counterparts shall together constitute
but one and the same document.

         (d) Except as expressly provided herein, the Rights Agreement is not
being amended, modified or supplemented in any respect, and it remains in full
force and effect.

         (e) This Amendment shall be deemed to be a contract made under the laws
of the State of North Carolina and for all purposes shall be governed by and
construed in accordance with the laws of such State applicable to contracts made

written above, as if executed on such date.
