         W I T N E S S E T H

         WHEREAS, the Issuers and the Original Guarantors have previously
executed and delivered to the Trustee an indenture (as supplemented from time to
time, the "Indenture"), dated as of February 9, 2000, providing for the issuance
of an aggregate principal amount of up to $300,000,000 of 12 3/4% Senior
Subordinated Notes due 2010;

         WHEREAS, the Indenture provides that the Guaranteeing Subsidiaries
shall execute and deliver to the Trustee a supplemental indenture pursuant to
which the Guaranteeing Subsidiaries shall unconditionally guarantee all of the
Issuers' obligations under the Securities and the Indenture on the terms and
conditions set forth in the Indenture; and

         WHEREAS, pursuant to Section 9.1 of the Indenture, the Trustee is
authorized to execute and deliver this Supplemental Indenture.

         NOW THEREFORE, in consideration of the foregoing and for other good and
valuable consideration, the receipt of which is hereby acknowledged, the parties
hereto mutually covenant and agree for the equal and ratable benefit of the
Holders of the Securities as follows:

         1. AGREEMENT TO GUARANTEE. The Guaranteeing Subsidiaries hereby agree
as follows:

(a)         Along with all Guarantors named in the Indenture, to jointly and
            severally, unconditionally and irrevocably guarantee, on a senior
            subordinated basis (each such guarantee to be referred to herein as
            a "Note Guarantee") to each Holder of a Security authenticated and
            delivered by the Trustee and to the Trustee and its successors and
            assigns, irrespective of the validity and enforceability of the
            Indenture, this Supplemental Indenture, the Securities or the
            obligations of the Issuers or any other Guarantors to the Holders or
            the Trustee hereunder or thereunder, that: (i) the principal of,
            premium, if any, and interest on the Securities shall be duly and
            punctually paid in full when due, whether at maturity, upon
            redemption at the option of Holders pursuant to the provisions of
            the Securities relating thereto, by acceleration or otherwise, and
            interest on the overdue principal and (to the extent permitted by
            law) interest, if any, on the Securities and all other obligations
            of the Issuers or the Guarantors to the Holders or the Trustee
            hereunder or thereunder (including amounts due the Trustee under
            Section 7.7 of the Indenture) and all other obligations shall be
            promptly paid in full or performed, all in accordance with the terms
            hereof and thereof; and (ii) in case of any extension of time of
            payment or renewal of any Securities or any of such other
            obligations, the same shall be promptly paid in full when due or
            performed in accordance with the terms of the extension or renewal,
            whether at maturity, by acceleration or otherwise. Failing payment
            when due of any amount so guaranteed, or failing performance of any
            other obligation of the Issuers to the Holders under the Indenture
            or under the Securities, for whatever reason, each Guaranteeing
            Subsidiary shall be obligated to pay, or to perform or cause the
            performance of, the same immediately. An Event of Default under the
            Indenture or the Securities shall constitute an event of default
            under this Note Guarantee, and shall entitle the Holders of
            Securities to accelerate the obligations of the Guaranteeing
            Subsidiaries hereunder in the same manner and to the same extent as
            the obligations of the Issuers.
<PAGE>   2

(b)         The Guaranteeing Subsidiaries' obligations hereunder shall be
            unconditional, irrespective of the validity, regularity or
            enforceability of the Securities or this Supplemental Indenture, the
            absence of any action to enforce the same, any waiver or consent by
            any Holder of the Securities with respect to any provisions hereof
            or thereof, any release of any other Guarantor, the recovery of any
            judgment against an Issuer, any action to enforce the same, whether
            or not a Guarantee is affixed to any particular Security, or any
            other circumstance which might otherwise constitute a legal or
            equitable discharge or defense of a Guarantor. Each of the
            Guaranteeing Subsidiaries hereby waive the benefit of diligence,
            presentment, demand of payment, filing of claims with a court in the
            event of insolvency or bankruptcy of an Issuer, any right to require
            a proceeding first against an Issuer, protest, notice and all
            demands whatsoever and covenants that its Note Guarantee shall not
            be discharged except by complete performance of the obligations
            contained in the Securities, the Indenture and this Note Guarantee.
            This Note Guarantee is a guarantee of payment and not of collection.
            If any Holder or the Trustee is required by any court or otherwise
            to return to the Issuers or to any Guarantor, or any custodian,
            trustee, liquidator or other similar official acting in relation to
            an Issuer or such Guarantor, any amount paid by an Issuer or such
            Guarantor to the Trustee or such Holder, this Note Guarantee, to the
            extent theretofore discharged, shall be reinstated in full force and
            effect. Each Guarantor further agrees that, as between it, on the
            one hand, and the Holders of Securities and the Trustee, on the
            other hand, (i) subject to the provisions hereof, the maturity of
            the obligations guaranteed hereby may be accelerated as provided in
            Article Six of the Indenture for the purposes of this Note
            Guarantee, notwithstanding any stay, injunction or other prohibition
            preventing such acceleration in respect of the obligations
            guaranteed hereby, and (ii) in the event of any acceleration of such
            obligations as provided in Article Six of the Indenture, such
            obligations (whether or not due and payable) shall forthwith become
            due and payable by the Guaranteeing Subsidiaries for the purpose of
            this Note Guarantee.

(c)         Each Guaranteeing Subsidiary that makes a payment or distribution
            under a Note Guarantee shall be entitled to a contribution from each
            other Guarantor on a PRO RATA basis, based on the net assets of each
            Guarantor, determined in accordance with GAAP.

(d)         The Obligations of each Guaranteeing Subsidiary under its Note
            Guarantee are limited to the maximum amount which, after giving
            effect to all other contingent and fixed liabilities of such
            Guaranteeing Subsidiary (including its guarantee of obligations in
            respect of the Senior Secured Credit Agreement and any other
            Guarantor Senior Debt), and after giving effect to any collections
            from or payments made by or on behalf of any other Guarantor in
            respect of the obligations of such other Guarantor under its
            Guarantee or pursuant to its contribution obligations under the
            Indenture, will result in the obligations of such Guaranteeing
            Subsidiary under the Note Guarantee not constituting a fraudulent
            conveyance or fraudulent transfer under federal or state law.

         2. INCORPORATION OF TERMS OF INDENTURE. The obligations of the
Guaranteeing Subsidiaries under the Note Guarantees shall be governed in all
respects by the terms of the Indenture and shall constitute a Guarantee
thereunder. Each of the parties hereto shall be bound by the terms of the
Indenture as they relate to the Note Guarantees.

         3. NO RECOURSE AGAINST OTHERS. No stockholder, officer, director,
employee or incorporator, past, present or future, or any Guaranteeing
Subsidiary, as such, shall have any personal liability under this Note Guarantee
by reason of his, her or its status as such stockholder, officer, director,
employee or incorporator.

         4. NEW YORK LAW TO GOVERN. THE INTERNAL LAW OF THE STATE OF NEW YORK
SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE BUT WITHOUT
GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT
THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

         5. COUNTERPARTS. The parties may sign any number of copies of this
Supplemental Indenture. Each signed copy shall be an original, but all of them
together represent the same agreement.

         6. EFFECT OF HEADINGS. The Section headings herein are for convenience
only and shall not affect the construction hereof.

         7. DISCLAIMER BY TRUSTEE. The Trustee makes no representation as to the
validity of this Supplemental Indenture or the proper authorization or due
execution of this Supplemental Indenture by the Issuers, the Original Guarantors
or the Guaranteeing Subsidiaries.

or

                           (v) Executive has engaged in willful and deliberate
conduct or activities intended to materially damage the business of the Company,
it being understood that neither conduct or activities pursuant to the

that such information constitutes valuable, special and unique property of the
Company. For the period of time which is the greater of (i) the fourth
anniversary of the date hereof or (ii) one year after the Executive is no longer
employed by the Company ("Confidentiality Period"), Executive agrees not to
disclose or use, except in the discharge of his duties and responsibilities
hereunder, any such confidential information, including without limitation,
information regarding research, developments, product designs or specifications,
manufacturing processes, "know-how," prices, suppliers, customers, costs or any
knowledge or information with respect to confidential or trade secrets of the
Company. Notwithstanding the preceding sentence, it is understood that such
confidential information does not include information that is publicly available
unless such information became publicly available as a result of a breach of
this Section 10 or information that is required by law or the order of any
governmental authority under color of law to be disclosed. Executive
acknowledges and agrees that all notes, records, reports, sketches, plans,
unpublished memoranda or other documents belonging to the Company, but held by
Executive, concerning any information relating to the Company's business,
whether confidential or not, are the property of the Company and will be
promptly delivered to it upon Executive's leaving the employ of the Company.
Executive also agrees to execute such confidentiality agreements that the Board
may adopt, and may modify from time to time, as a standard form to be executed

restrictive than the provisions of this Agreement.

         12. REPURCHASE PROVISIONS.

                  (a) Prior to a Qualified Public Offering (as that term is
defined in that certain Stockholders Agreement of Orius dated as of February 26,
1999, as amended), in the event the Executive is either terminated for Cause (as
defined in Section 7(a)) of this Agreement) or resigns from employment with the
Company other than for Good Reason ("Repurchase Termination"), all of the
Executive's shares of Common stock of Orius, whether held by Executive or
transferred by Executive to one or more transferees (collectively, the
"Executive Stock"), shall be subject to repurchase by Orius as set forth in this
Section 12 (the "Repurchase Option").

                  (b) Following any Repurchase Termination, Orius shall have the
right, but not the obligation, to purchase all or any portion of the Executive
Stock for the book value of such securities based on the most recent financial
statement of Orius available prior to such repurchase and without reference to
such repurchase. Such right to purchase may be exercised only once.

                  (c) The Board of Directors of Orius may elect to exercise the
Repurchase Option by delivering written notice (the "Repurchase Notice") to the
holder or holders of such stock within forty-five (45) days after the date of
the Repurchase Termination. The Repurchase Notice will set forth the number of
shares of the Executive Stock to be acquired from each holder, the aggregate
consideration to be paid for such shares and the time and place for the closing
of the transaction.

                  (d) The closing of the purchase of the Executive Stock
pursuant to the Repurchase Option shall take place on the date designated by
Orius in the Repurchase Notice, which date shall not be more than forty-five
(45) days nor less than two (2) business days after the delivery of the
Repurchase Notice. Orius shall pay for the Executive Stock to be purchased
pursuant to the Repurchase Option by delivery of (i) a check or wire transfer of
funds, (ii) a subordinated note or notes payable prior to the first anniversary
of the closing of such purchase, bearing interest at a rate per annum equal to
the prime rate of interest as announced by Citibank, N.A. and secured by a
pledge of the Executive Stock purchased, or (iii) both (i) and (ii), in the
aggregate amount of the purchase price for such shares; provided that Orius
shall use reasonable efforts to make all such repurchases with a check or wire
transfer of funds unless prohibited by law or by its lenders (in writing). Any
notes issued by Orius pursuant to this Section 12(d) shall be subject to any
restrictive covenants to which Orius is subject at the time of such purchase.
Orius shall be entitled to receive customary representations and warranties as
to title from the sellers regarding such sale and to require all sellers'
signatures be guaranteed. Orius may elect to assign its right to purchase to the
stockholders of Orius (which rights to purchase shall be distributed pro rata to
all stockholders (other than the Executive), based upon the number of votes held
by such stockholders). In the event Orius elects to assign its rights to the
other stockholders of Orius (other than the Executive) such other stockholders
shall have the same right as Orius to purchase stock pursuant to the Repurchase
Notice but shall be obligated to make payment therefor only by delivery of a
check or wire transfer of funds.

                  (e) Notwithstanding anything to the contrary contained in this
Agreement, all repurchases of the Executive Stock by Orius hereunder shall be
subject to applicable restrictions contained in the Florida Business Corporation
Act and in Orius's and its subsidiaries' debt and

                                       6
<PAGE>   7

equity financing agreements. If any such restrictions prohibit the repurchase of
the Executive Stock hereunder which Orius is otherwise entitled or required to
make, Orius may make such repurchases as soon as it is permitted to do so under
such restrictions, but in any event within 180 days of the Repurchase
Termination.

                  (f) Notwithstanding anything to the contrary contained in this
Agreement, Orius's right to repurchase the Executive Stock shall terminate upon
the consummation of a Qualified Public Offering.

         13. ENTIRE AGREEMENT; MODIFICATION.

                  (a) This Agreement contains the entire agreement of the
Company and Executive, and the Company and Executive hereby acknowledge and
agree that this Agreement supersedes any prior statements, writings, promises,
understandings or commitments between the parties hereof.

                  (b) No future oral statements, promises or commitments with
respect to the subject matter hereof, or other purported modification hereof,
shall be binding upon the parties hereto unless the same is reduced to writing
and signed by each party hereto.

         14. ASSIGNMENT. The rights and obligations of the parties under this
Agreement shall inure to the benefit of and shall be binding upon the successors
and permitted assigns of the parties. Neither party may assign his or its rights
or obligations under this Agreement without the prior written consent of the
other party.

         15. TERMINATION. All of the provisions of this Agreement shall
terminate after the expiration of the Term of this Agreement, except that (i)
Section 10 shall only terminate upon the expiration of the Confidentiality
Period and (ii) Section 12 shall only terminate upon a Qualified Public
Offering.

         16. NO MITIGATION. The Executive shall not be required to mitigate the
amount of any payments due hereunder upon termination of Executive's employment
by seeking other employment or otherwise, nor shall the amount of any such
payments be reduced by any employment by another employer after termination of
Executive's employment hereunder.

         17. MISCELLANEOUS.

                  (a) The section headings contained herein are for reference
purposes only and shall not in any way affect the meaning or the interpretation
of this Agreement.

                  (b) The failure of any party to enforce any provision of this
Agreement shall in no manner affect the right to enforce the same, and the
waiver by any party of any breach of any provision of this Agreement shall not
be construed to be a waiver by such party of any succeeding breach of such
provision or a waiver by such party of any breach of any other provision.

illegal or unenforceable provision shall be replaced by a mutually acceptable
valid, and enforceable provision which comes closest to the intent of the
parties.

the provisions contained in this Agreement shall be entitled to reimbursement

counterparts, each of which shall constitute an original and all of which
together shall constitute one and the same instrument.
