all authorizations, permits and licenses required by the FCC or the PUC or any Communications Law for the conduct of their business as now conducted, and all such regulatory authorizations are in full force and effect, are subject to no further

 15 

  
 cash flows and stockholders’ deficiency of the Company and its Subsidiaries
for the fiscal year then ended (the “Audited Financials”). The Audited Financials were prepared in accordance with GAAP, are true and correct in all material respects and fairly present the Company’s and its Subsidiaries’

model submitted to the Company’s senior lenders in September 2002 and the other is the revised model giving effect to the investment of $5 million in the Notes and adjustments in the amortization of the principal amounts payable under the
Senior Credit Facility. These projected financial statements were based on estimates, information and assumptions believed by the Company to be reasonable, and the Company has no reason to believe, in the light of conditions existing at the time of
delivery, that such projections were incorrect or misleading in any material respect. 
  
 Section

of Capital Stock of the Company and all convertible securities, options, warrants and similar rights held with respect to the Capital Stock of the Company have been duly authorized, validly issued and, in the case of Capital Stock, are fully paid
and nonassessable.

the ordinary course in all material respects. 
  
 Section 4.10    Title to Properties;
Possession Under Leases. The Company and each of its Subsidiaries has good and marketable title to, or valid leasehold interests in, all of its material properties and assets free and clear of Liens, other than Permitted

obligations under any of the Leases. The Company’s and each of its Subsidiaries’ possession of any property leased by it has not been disturbed, nor has any claim been asserted against the Company or such Subsidiary that is or could be

restrictive covenant, license, indenture, contract or other agreement, instrument or obligation to which it is a party or by which it is bound or to which its assets are subject, which breach, default or violation would reasonably be expected to
result in a Material Adverse Effect.

Subsidiaries is a party or by which the Company or any of its Subsidiaries or any of their assets is bound (collectively, the “Contracts”), except for defaults or alleged defaults which, in the aggregate, could not reasonably be expected
to have a Material Adverse Effect and, to the knowledge of the Company, no party other than the Company or any of its Subsidiaries is in default with respect to such party’s obligations under any of the Contracts, except for defaults which, in
the aggregate, could not reasonably be expected to have a Material Adverse Effect. As of the date hereof, no claim has been asserted against the Company or any of its Subsidiaries that is or could be materially adverse to its interests under any of

aside on its books adequate reserves.

unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit action or proceeding arising out of or relating to this Agreement or the other
Loan Documents in any North Carolina state or Federal court. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any
such court. 
  
 (c)  Each party to this Agreement irrevocably consents to service of
process in the manner provided for notices in Section 9.1. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law. 
  
 Section 9.13    Consents and Approvals; Defaults. 
  
 (a)  Subject to the terms of the Subordination Agreement and the terms of paragraph (c) of this Section, to the extent that (i) the terms of this Agreement or any
of the other Loan Documents require the Company to obtain the consent or approval of the Holders, (ii) the Company seeks an amendment to or termination of any of the terms of 

 
 31 

  
 this Agreement or any of the Loan Documents or (iii) the Company seeks a waiver
of any right granted to the Holders under this Agreement or any of the Loan Documents, such consent, approval, termination, amendment or waiver (each, an “Approval”) shall be made in writing by the Holders of Notes representing at least a
majority of the aggregate principal amount outstanding under all of the Notes. 
  
 (b)  Subject to the terms of paragraph (c) of this Section, to the extent that the terms of this Agreement permit the Holders to take any enforcement action, including but not limited to declaring an Event of Default or
accelerating amounts due hereunder or under the Notes, the taking of any such action shall require the written consent of the Holders of Notes representing at least a majority of the aggregate principal amount outstanding under all of the Notes.

  
 (c)  Notwithstanding anything to the contrary contained in paragraphs (a) or (b) of
this Section, the Holders shall not, without the prior written consent and approval of all of the affected Holders, amend, modify, terminate or obtain a waiver of any provision of this Agreement or any of the Loan Documents, which will have the
effect of (i) reducing the principal amount of any Notes or of any payment required to be made to the Holders hereunder or modifying the terms of a payment or prepayment thereof; (ii) reducing the Interest Rate or extending the time for payment of
interest under any Notes or (iii) releasing the Company from any obligation under this Agreement or any of the other Loan Documents. 
  
 (d)  Each Holder agrees that, for the benefit of the other Holders, any proceeds received by a Holder upon enforcement by the Holders of their rights and remedies under this Agreement, will
be divided, pro rata, among all Holders. 
  
 Section 9.14    Relationship of the Parties;
Advice of Counsel.  This Agreement provides for the making of an investment by the Holders, in their capacity as investors, in the Company, in its capacity as a borrower, and for the payment of interest and repayment of principal
under the Notes and this Agreement by the Company to the Holders. The provisions herein for delivery of financial statements are intended solely for the benefit of Holders to protect their interests as investors in assuring payments of interest and
repayment of principal, and nothing contained in this Agreement shall be construed as permitting or obligating a Holder, in its capacity as a Holder, to act as a financial or business advisor or consultant to the Company, as permitting or obligating
any Holder, in its capacity as a Holder, to control the Company or to conduct the Company’s operations, as creating any fiduciary obligation on the part of any such Holder to the Company or as creating any joint venture, agency or other
relationship between the parties other than as explicitly and specifically stated in this Agreement. The Holders, in their capacity as Holders, are not (and shall not be construed as) a partner, joint venturer, alter-ego, manager, controlling
person, operator or other business participant of any kind of the Company; neither the Holders nor the Company intends that the Holders assume such status, and, accordingly, the Holders, in their capacity as Holders, shall not be deemed responsible
for (or a participant in) any acts or omissions of the Company or any of its Subsidiaries. Each of the Holders and the Company represent and warrant to the other that it has had the advice of 

 
 32 

  
 experienced counsel of its own choosing in connection with the negotiation and execution of this
Agreement and with respect to all matters contained herein. 
  
 Section 9.15    Regulation
FD.  Each of the Holders agrees to maintain the confidentiality of all Information (as defined below) and to refrain from trading shares of any class of the Capital Stock of the Company while in possession of any material
Information, in each case so long as such Information is not publicly available, except that Information may be disclosed (a) to its directors, officers, employees and agents, including accountants, legal counsel and other advisors (limited, in the
case of outside directors, agents, accountants, legal counsel and other advisors, to those who expressly agree to keep all such Information confidential), it being understood that the Persons to whom such disclosure is made will be informed of the
confidential nature of such Information and instructed to keep such Information confidential and to refrain from trading the Capital Stock of the Company while in possession of any material Information, (b) to the extent requested by any regulatory
authority, (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) in connection with the exercise of any remedies hereunder or any suit, action or proceeding relating to this Agreement or the
enforcement of rights hereunder, (e) to any Permitted Transferee of any of its rights or obligations under this Agreement who becomes a party to this Agreement or (f) with the consent of the Company, as applicable. For the purposes of this Section,
“Information” means all non-public information received from the Company, or its Subsidiaries, relating to the Company or its Subsidiaries, their businesses, financial condition, results of operations and prospects. 

 
 Section 9.16    Registration and Transfer of Notes. 
  
  
 (a)  The Company will keep at its principal office a register in which
the Company will provide for the registration of the Notes and their transfer. The Company may treat any Person in whose name any Note is registered on such register as the owner thereof for the purpose of receiving payment of the principal of and
interest on such Note and for all other purposes, whether or not such Note shall be overdue, and the Company shall not be affected by any notice to the contrary from any Person other than the applicable Holder. All references in this Agreement to a
“Holder” of any Note shall mean the Person in whose name such Note is at the time registered on such register. 
  
 (b)  Upon surrender of any Note for registration of transfer or for exchange to the Company at its principal office, the Company at its expense will execute and deliver in exchange therefor a new Note or Notes, as
the case may be, of the same type in denominations of at least $100,000 (except a Note may be issued in a lesser principal amount if the unpaid principal amount of the surrendered Note is not evenly divisible by, or is less than, $100,000, as
requested by the Holder or transferee, which aggregate the unpaid principal amount of such Note, registered as such Holder or transferee may request, dated so that there will be no loss of interest on such surrendered Note and otherwise of like
tenor). 
  
 (c)  Upon receipt of evidence reasonably satisfactory to the Company of the
loss, theft, destruction or mutilation of any Note and, in the case of any such loss, theft or 

 
 33 

  
 destruction of any Note, upon delivery of an indemnity bond in such reasonable
amount as the Company may determine (or an unsecured indemnity agreement from the Holder reasonably satisfactory to the Company), or, in the case of any such mutilation, upon the surrender of such Note for cancellation to the Company at its
principal office, the Company at its expense will execute and deliver, in lieu thereof, a new Note of the same class and of like tenor, dated so that there will be no loss of interest on (and registered in the name of the Holder of) such lost,
stolen, destroyed or mutilated Note. Any Note in lieu of which any such new Note has been so executed and delivered by the Company shall be deemed to be not outstanding for any purpose of this Agreement. 
  
 Section 9.17    No Shorting Provisions. 
  
 (a)  Until the Notes held by a Holder are repaid in full, neither the Holder nor any of its Affiliates shall, directly or indirectly, engage in,
or advise, encourage or knowingly assist any third party to engage in, any practice that would commonly be understood to constitute a short sale of the Company’s Common Stock. Without limiting the generality of the foregoing, neither the Holder
nor any of its Affiliates shall (i) sell shares of the Company’s Common Stock that the Holder or such Affiliate does not own, consummate a sale of the Company’s Common Stock with shares borrowed by or for the account of the Holder of such
Affiliate or otherwise hold a net short position in shares of the Company’s Common Stock or (ii) lend shares of the Company’s Common Stock to short sellers. 
  
 (b)  Nothing in this Section shall limit any Holder or its Affiliates from engaging in bona fide cap or collar transactions on shares of the
Company’s Common Stock owned by such Holder or such Affiliate or from selling its shares of the Company’s Common Stock to the highest bidder in a public or private transaction.

 36FORM OF NOTE

  
 Exhibit 4.2 
  
 This Note has not been registered under the Securities Act of 1933, as amended, or applicable securities laws. This Note may not be offered, sold, assigned, transferred, pledged, hypothecated or
otherwise disposed of in the absence of an effective registration of the Note under such act and under any applicable state securities laws, unless such transaction is exempt from, or not subject to, registration and the issuer hereof is satisfied
that such registration is not required as to such transaction. 
  
 This instrument and the rights and obligations evidenced hereby
are subordinate in the manner and to the extent set forth in that certain Intercreditor and Subordination Agreement dated as of December 31, 2002 between General Electric Capital Corporation and certain subordinated creditors including the initial
holder hereof (the “Subordination Agreement”) to the “Senior Debt” (as defined in the Subordination Agreement), and each holder of this instrument, by its acceptance hereof, irrevocably agrees to be bound by the provisions
of the Subordination Agreement. 
  
 SENIOR SUBORDINATED NOTE 
  

	 Charlotte, North Carolina
 	 	 December     , 2002
 

 
 $                 
  
 FOR VALUE RECEIVED, US LEC Corp., a Delaware corporation (the “Company”), promises to pay to the order
of                 , his, her, or its successors, assigns or any subsequent holder of this Note (“Holder”),
at                 , or at such other place as may be designated in writing by Holder, in lawful money of the United States of America in immediately available
funds, the amount of                  DOLLARS ($                 ) or, if
less, the aggregate unpaid balance due to Holder under the Note Purchase Agreement of even date herewith by and among the Company and the Investors listed on Schedule A thereto, as amended, restated, supplemented or otherwise modified from time to
time (the “Note Purchase Agreement”). All capitalized terms used but not otherwise defined herein have the meanings given to them in the Note Purchase Agreement. This Note shall mature on December 31, 2007 (the “Maturity
Date”). 
  
 This Note is issued pursuant to the Note Purchase Agreement. Reference is made to (a) the
Note Purchase Agreement, which, among other things, permits the acceleration of the maturity hereof upon the occurrence of certain events and for prepayments in certain circumstances and to (b) the Subordination Agreement, which provides the terms
by which the indebtedness evidenced hereby is subordinated in right and time of payment to Senior Debt. 
  
 The
principal amount of the indebtedness evidenced hereby shall be payable in full on the Maturity Date. Interest thereon shall be paid until such principal amount is paid in full at the rate of 11% per annum, shall be calculated on the basis of a
365-day year and shall be computed for each payment period on the principal balance for the actual number of days outstanding. 

  
 Commencing on February 1, 2003, and continuing on the first day of each
succeeding calendar month thereafter, up to and including the Maturity Date, interest shall be payable in arrears by the Company in cash at a rate of 11% per annum. 
  
 Whenever any payment (including principal of and interest on this Note, or other amounts) hereunder shall become due, or otherwise would occur, on a day that is not a
Business Day, such payment may be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of interest. 
  
 Upon the occurrence of any one or more of the Events of Default specified in the Note Purchase Agreement, all or any portion of the amounts then remaining unpaid on this
Note may become or be declared immediately due and payable as provided in the Note Purchase Agreement, without further notice. 
  
 Demand, presentment, notice and protest are expressly waived by the Company, except for notices to the Company otherwise expressly required in the Note Purchase Agreement. 
  
 In the event this Note is placed in the hands of one or more attorneys for collection or enforcement or protection of Holder’s rights described herein or in the Note
Purchase Agreement, the Company agrees to pay all reasonable attorneys’ fees and all court and other out-of-pocket costs incurred by Holder. 
  
 This Note is governed by and shall be construed in accordance with the law of the State of Delaware. If any provision of this Note should for any reason be invalid or unenforceable, the remaining
provisions shall remain in full force and effect. 
  
 This Note may not be changed, extended or terminated except in
writing. No waiver of any term or provision hereof shall be valid unless in writing signed by Holder or Holders as provided in the Note Purchase Agreement. 
  
 Executed as of December     , 2002.
