Item 14. Indemnification of Directors and Officers.

     Certain provisions of the Company's Certificate of Incorporation (the
"Certificate") and Bylaws provide that the Company shall indemnify all of its
directors and officers to the fullest extent permitted by the General
Corporation Law of the State of Delaware (the "Delaware Law"). In addition, the
Certificate authorizes the Registrant to enter into one or more agreements with
any person which provide for indemnification greater or different than that
provided in its Certificate.

     Section 145 of the Delaware Law permits a corporation to indemnify its
directors and officers against expenses (including attorney's fees), judgments,
fines and amounts paid in settlements actually and reasonably incurred by them
in connection with any action, suit or proceeding, whether criminal or civil,
brought by a third party if such directors or officers acted in good faith and
in a manner they reasonably believed to be in or not opposed to the best
interests of the corporation and, with respect to any criminal action or
proceeding, had no reason to believe their conduct was unlawful. In a
derivative action, indemnification may be made only for expenses actually and
reasonably incurred by directors and officers in connection with the defense or
settlement of an action or suit and only with respect to a matter as to which
they shall have acted in good faith and in a manner they reasonably believed to
be in or not opposed to the best interest of the corporation, except that no
indemnification shall be made if such person shall have been adjudged liable to
the corporation, unless and only to the extent that the court in which the
action or suit was brought shall determine upon application that the defendant
officers or directors are reasonably entitled to indemnity for such expenses
despite such adjudication of liability.

     In addition, Section 102 of the Delaware Law provides that a corporation
may include in its certificate of incorporation a provision eliminating or
limiting the personal liability of directors for monetary damages for breach of
fiduciary duty, provided that such provision shall not eliminate or limit the
liability of a director: (i) for any breach of the director's duty of loyalty
to the corporation or its stockholders; (ii) for acts or omissions not in good
faith that involve intentional misconduct or a knowing violation of the law;
(iii) conduct in violation of Section 174 of the Delaware Law (which section
relates to unlawful distributions); or (iv) for any transaction from which the
director derived an improper personal benefit. The Certificate currently
includes such provisions.

     Reference is also hereby made to Section 8 of the Underwriting Agreement,
a copy of which is filed as Exhibit 1 to this Registration Statement, for
information concerning indemnification arrangements among the Company and the
Underwriters.


Item 15. Recent Sales of Unregistered Securities.
     On December 31, 1997, US LEC L.L.C., a Delaware limited liability company,
was merged into the Company (the "Merger"). As a result of the Merger, the
Company issued (i) 3,855,000 shares of Class A Common


                                      II-1
<PAGE>

Stock to the holders of all outstanding nonvoting units of membership interest
in US LEC L.L.C (the "Nonvoting Units"), (ii) 16,594,500 shares of Class B
Common Stock to the holders of all outstanding voting units of membership
interest in US LEC L.L.C. (the "Voting Units") and (iii) warrants to purchase
444,000 shares of Class A Common Stock to the holders of all outstanding
warrants to purchase Nonvoting Units (the "Warrants"). Immediately prior to the
Merger, the 2,570 outstanding Nonvoting Units were beneficially owned by a
total of 53 persons, including employees of US LEC L.L.C. and private
investors, the 11,063 outstanding Voting Units were beneficially owned by
Messrs. Aab and Ganatra and the Warrants were held by three employees and a
sales agent of US LEC L.L.C. The transaction was not registered under the
Securities Act pursuant to the exemption provided by Section 4(2) thereof for
transactions not involving any public offering.
     In January 1998, the Company granted incentive stock options to 96
employees covering 182,800 shares of Class A Common Stock. These transactions
were not registered under the Securities Act pursuant to the exemption provided
by Rule 701 promulgated thereunder for sales of securities pursuant to
compensatory benefit plans.
     In February, 1998, Mr. Aab exchanged a note payable by Company to him in
the amount of $5,000,000 for 480,770 shares of Class B Common Stock. The
transaction was not registered under the Securities Act pursuant to the
exemption provided by Section 4(2) thereof for transactions not involving any
public offering.

Item 17. Undertakings.

     The undersigned Registrant hereby undertakes that:

     (1) For purposes of determining any liability under the Securities Act of
1933, the information omitted from the form of Prospectus filed as part of this
Registration Statement in reliance upon Rule 430A and contained in a form of
Prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this Registration
Statement as of the time it was declared effective;

     (2) For the purpose of determining any liability under the Securities Act
of 1933, each post-effective amendment that contains a form of Prospectus shall
be deemed to be a new Registration Statement relating to the securities offered
therein, and the offering of such securities at that item shall be deemed to be
the initial bona fide public offering thereof; and

     (3) The undersigned Registrant hereby undertakes to provide to the
Underwriters at the closing specified in the Underwriting Agreement,
certificates in such denominations and registered in such names as required by
the Underwriters to permit prompt delivery to each purchaser.

     Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act of 1933 and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act of 1933 and will be governed by the final adjudication of such
issue.

         Commission either (1) prior to the Effective Date of such registration

         (including the form of final prospectus) or (2) after the Effective
         Date of such registration statement, a final prospectus in accordance
         with Rules 430A and 424(b). In the case of clause (2), the Company has

         the Act to be included in such registration statement and the

         such final prospectus, shall contain all Rule 430A Information,
         together with all other such required information, and, except to the
         extent the Representatives shall agree in writing to a modification,

         similar coverage from similar insurers as may be necessary to continue
         its business at a cost that would not have a material adverse effect on

         with management's general or specific authorization; and (iv) the

         action designed to or which has constituted or which might reasonably
         be expected to cause or result, under the Exchange Act or otherwise, in

         give rise to potential liability, for the investigation or remediation
         of any disposal or release of hazardous or toxic substances or wastes,
         pollutants or contaminants, except where such non-compliance with
         Environmental Laws, failure to receive or comply with required permits,
         licenses or other approvals, or liability would not, individually or in
         the aggregate, have a material adverse change in the condition

         arising from transactions in the ordinary course of business, except as

         governmental bodies, arbitrators or other authorities with respect to
         such filings or submissions except where the deficiency is of such a
         nature that failure to cure any such deficiency would not have a

         knowledge, the information contained in such filings or submissions was

                  2. Purchase and Sale. (a) Subject to the terms and conditions
and in reliance upon the representations and warranties herein set forth, the

the representations and warranties herein set forth, the Company hereby grants
an option to the several Underwriters to purchase, severally and not jointly, up
to 825,000 Option Securities at the same purchase price per share as the
Underwriters shall pay for the Underwritten Securities. Said option may be
exercised only to cover over-allotments in the sale of the Underwritten

your absolute discretion shall make to eliminate any fractional shares.

                  3. Delivery and Payment. Delivery of and payment for the
Underwritten Securities and the Option Securities (if the option provided for in
Section 2(b) hereof shall have been exercised on or before the third Business
Day prior to the Closing Date) shall be made at 10:00 AM, New York City time, on
[_________], 1998, or at such time on such later date not more than three
Business Days after the foregoing date as the Representatives shall designate,
which date and time may be postponed by agreement between the Representatives
and the Company or as provided in Section 9 hereof (such date and time of
delivery and payment for the Securities being herein called the "Closing Date").
Delivery of the Securities shall be made to the Representatives for the
respective accounts of the several Underwriters against payment by the several
Underwriters through the Representatives of the purchase price thereof to or

Days after exercise of said option) for the respective accounts of the several
Underwriters, against payment by the several Underwriters through the
Representatives of the purchase price thereof to or upon the order of the

the Company. If settlement for the Option Securities occurs after the Closing
Date, the Company will deliver to the Representatives on the settlement date for
the Option Securities, and the obligation of the Underwriters to purchase the
Option Securities shall be conditioned upon receipt of, supplemental opinions,
certificates and letters confirming as of such date the opinions, certificates
and letters delivered on the Closing Date pursuant to Section 6 hereof.

                  4. Offering by Underwriters. It is understood that the several
Underwriters propose to offer the Securities for sale to the public as set forth
in the Prospectus.

                  5. Agreements. The Company agrees with the several
Underwriters that:

                  (a) The Company will use its best efforts to cause the
         Registration Statement, if not effective at the Execution Time, and any
         amendment thereof, to become effective. Prior to the termination of the
         offering of the Securities, the Company will not file any amendment to
         the Registration Statement or supplement to the Prospectus or any Rule
         462(b) Registration Statement unless the Company has furnished you a
         copy for your review prior to filing and will not file any such
         proposed amendment or supplement to which you reasonably object.
         Subject to the foregoing sentence, if the Registration Statement has

                                       10

<PAGE>


         become or becomes effective pursuant to Rule 430A, or filing of the
         Prospectus is otherwise required under Rule 424(b), the Company will
         cause the Prospectus, properly completed, and any supplement thereto to
         be filed with the Commission pursuant to the applicable paragraph of
         Rule 424(b) within the time period prescribed and will provide evidence
         satisfactory to the Representatives of such timely filing. The Company
         will promptly advise the Representatives (1) when the Registration
         Statement, if not effective at the Execution Time, shall have become
         effective, (2) when the Prospectus, and any supplement thereto, shall
         have been filed (if required) with the Commission pursuant to Rule
         424(b) or when any Rule 462(b) Registration Statement shall have been
         filed with the Commission, (3) when, prior to termination of the
         offering of the Securities, any amendment to the Registration Statement
         shall have been filed or become effective, (4) of any request by the
         Commission or its staff for any amendment of the Registration Statement
         or any Rule 462(b) Registration Statement, or for any supplement to the
         Prospectus or for any additional information, (5) of the issuance by
         the Commission of any stop order suspending the effectiveness of the
         Registration Statement or the institution or threatening of any
         proceeding for that purpose and (6) of the receipt by the Company of
         any notification with respect to the suspension of the qualification of
         the Securities for sale in any jurisdiction or the institution or
         threatening of any proceeding for such purpose. The Company will use
         its best efforts to prevent the issuance of any such stop order or the
         suspension of any such qualification and, if issued, to obtain as soon
         as possible the withdrawal thereof.

                  (b) If, at any time when a prospectus relating to the
         Securities is required to be delivered under the Act, any event occurs
         as a result of which the Prospectus as then supplemented would include
         any untrue statement of a material fact or omit to state any material
         fact necessary to make the statements therein in the light of the
         circumstances under which they were made not misleading, or if it shall
         be necessary to amend the Registration Statement or supplement the
         Prospectus to comply with the Act, the Company promptly will (1) notify
         the Representatives of any such event; (2) prepare and file with the
         Commission, subject to the second sentence of paragraph (a) of this
         Section 5, an amendment or supplement which will correct such statement
         or omission or effect such compliance; and (3) supply any supplemented
         Prospectus to you in such quantities as you may reasonably request.

                  (c) As soon as practicable, the Company will make generally
         available to its security holders and to the Representatives an
         earnings statement or statements of the Company and its Subsidiaries
         which will satisfy the provisions of Section 11(a) of the Act and Rule
         158 promulgated under the Act.

                  (d) The Company will furnish to the Representatives and
         counsel for the Underwriters signed copies of the Registration
         Statement (including exhibits thereto) and to each other Underwriter a
         copy of the Registration Statement (without exhibits thereto) and, so
         long as delivery of a prospectus by an Underwriter or dealer may be
         required by the Act, as many copies of each Preliminary Prospectus and
         the Prospectus and any supplement thereto as the Representatives may
         reasonably request.

                  (e) The Company will arrange, if necessary, for the
         qualification of the Securities for sale under the laws of such
         jurisdictions as the Representatives may designate and will maintain
         such qualifications in effect so long as required for the distribution
         of the Securities; provided that in no event shall the Company be
         obligated to qualify to do business in any jurisdiction where it is not
         now so qualified or to take any action that would subject it to service
         of process in suits, other than those arising out of the offering or
         sale of the Securities, in any jurisdiction where it is not now so
         subject.

                  (f) The Company will not, without the prior written consent of
         Smith Barney Inc., for a period of 180 days following the Execution
         Time, offer, sell or contract to sell, or otherwise dispose of (or
         enter into any transaction which is designed to, or might reasonably be
         expected to, result in the disposition (whether by actual disposition
         or effective economic disposition due to cash settlement or otherwise)
         by the Company or any affiliate of the Company or any person in privity
         with the Company or any affiliate of the Company) directly or
         indirectly, or announce the offering of, any other shares of Common
         Stock or any securities convertible into, or exchangeable for, shares
         of Common Stock; provided, however, that the Company may issue and sell
         Common Stock pursuant to any employee stock option plan in effect at
         the Execution Time and the Company may issue Common Stock issuable upon
         the conversion of securities or the exercise of warrants outstanding at
         the Execution Time.

                  (g) The Company will not take, directly or indirectly, any
         action designed to or which has constituted or which might reasonably
         be expected to cause or result, under the Exchange Act or otherwise, in
         stabilization or manipulation of the price of any security of the
         Company to facilitate the sale or resale of the Securities.

                  (h) The Company agrees to pay the costs and expenses relating
         to the following matters: (i) the preparation, printing or reproduction
         and filing with the Commission of the Registration Statement (including
         financial statements and exhibits thereto), each Preliminary
         Prospectus, the Prospectus, and each amendment or supplement to any of
         them; (ii) the printing (or reproduction) and delivery (including

         registration of the Securities under the Exchange Act and the listing

         its obligations hereunder.

                  6. Conditions to the Obligations of the Underwriters. The
obligations of the Underwriters to purchase the Underwritten Securities and the

                  and "Business - Legal Proceedings," fairly summarize the

                           (v) the Registration Statement has become effective

                  information contained therein, as to which such counsel need
                  express no opinion) comply as to form in all material respects
                  with the applicable requirements of the Act and the rules

                  material fact or omitted or omits to state any material fact
                  required to be stated therein or necessary to make the
                  statements therein not misleading or that the Prospectus as of
                  its date and on the Closing Date includes any untrue statement
                  of a material fact or omitted or omits to state a material
                  fact necessary to make the statements therein, in the light of
                  the circumstances under which they were made, not misleading
                  (in each case, other than the financial statements and other
                  financial information contained therein, as to which such
                  counsel need express no belief);

                           (vi) this Agreement has been duly authorized,
                  executed and delivered by the Company;

                           (vii) the Company is not and, after giving effect to
                  the offering and sale of the Securities and the application of
                  the proceeds thereof as described in the Prospectus, will not
                  be, an "investment company" as defined in the Investment
                  Company Act of 1940, as amended;

                           (viii) no consent, approval, authorization, filing
                  with or order of any court or governmental agency or body is
                  required in connection with the transactions contemplated
                  herein, except such as have been obtained under the Act and
                  such as may be required under the blue sky laws of any
                  jurisdiction in connection with the purchase and distribution
                  of the Securities by the Underwriters in the manner
                  contemplated in this Agreement and in the Prospectus;

                           (ix) neither the execution of the Registration
                  Statement and the execution and delivery of this Agreement nor
                  the issue and sale of the Securities, nor the consummation of
                  any other of the transactions herein contemplated nor the
                  fulfillment of the terms hereof will conflict with, result in
                  a breach or violation of or imposition of any lien, charge or
                  encumbrance upon any property or assets of the Company or its
                  Subsidiaries pursuant to, (i) the certificate of incorporation
                  or by-laws (or equivalent governing documents) of the Company
                  or any of its 

                                       15

                  Subsidiaries, (ii) the terms of any indenture, contract,
                  lease, mortgage, deed of trust, note agreement, loan agreement
                  or other agreement, obligation, condition, covenant or
                  instrument to which the Company or any of its Subsidiaries is
                  a party or bound or to which its or their property is subject
                  which is known to such counsel, (iii) any statute, law, rule,
                  regulation, judgment, order, decision or decree applicable to
                  the Company or any of its Subsidiaries of any court,
                  regulatory body, administrative agency, governmental body,
                  arbitrator or other authority having jurisdiction over the
                  Company or its Subsidiaries or any of its or their properties,
                  or (iv) any license, permit, certificate or authorization; and

                           (x) to such counsel's knowledge, no holders of
                  securities of the Company have rights to the registration of
                  such securities under the Registration Statement.

         In rendering such opinion, such counsel may rely (A) as to matters
         involving the application of laws of any jurisdiction other than the
         State of New York, the State of North Carolina, the General Corporation
         Law of the State of Delaware or the federal laws of the United States,
         to the extent they deem proper and specified in such opinion, upon the
         opinion of other counsel of good standing whom they believe to be
         reliable and who are satisfactory to counsel for the Underwriters and
         (B) as to matters of fact, to the extent they deem proper, on
         certificates of responsible officers of the Company and public
         officials. References to the Prospectus in this paragraph (b) include
         any supplements thereto at the Closing Date.

                  (c) The Company shall have furnished to the Representatives
         the opinion of Swidler & Berlin, special federal regulatory counsel for
         the Company dated the Closing Date and addressed to the
         Representatives, substantially in the form of Exhibit B hereto.

                  (d) The Company shall have furnished to the Representatives
         opinions of local counsel from each state where the Company or its
         Subsidiaries hold any license, permit, certificate or authorization,
         from counsel acceptable to the Representatives, dated the Closing Date
         and addressed to the Representatives substantially in the form of
         Exhibit C hereto.

                  (e) The Representatives shall have received from Paul,
         Hastings, Janofsky & Walker LLP, counsel for the Underwriters, such
         opinion or opinions, dated the Closing Date and addressed to the
         Representatives, with respect to the issuance and sale of the
         Securities, the Registration Statement, the Prospectus (together with
         any supplement thereto) and other related matters as the
         Representatives may reasonably require, and the Company shall have
         furnished to such counsel such documents as they request for the
         purpose of enabling them to pass upon such matters. The opinion or
         opinions of such counsel shall be rendered to the Underwriters at the
         request of the Company and shall so state therein.

                  (f) The Company shall have furnished to the Representatives a
         certificate of the Company, signed by the Chairman of the Board or the
         President and the principal financial or accounting officer of the
         Company, dated the Closing Date, to the effect that the signers of such
         certificate have carefully examined the Registration Statement, the
         Prospectus, any supplements to the Prospectus and this Agreement and
         that:

                           (i) the representations and warranties of the Company
                  in this Agreement are true and correct in all material
                  respects on and as of the Closing Date with the same effect as
                  if made on the Closing Date and the Company has complied with
                  all the agreements and satisfied all the conditions on its
                  part to be performed or satisfied at or prior to the Closing
                  Date;

                           (ii) no stop order suspending the effectiveness of
                  the Registration Statement has been issued and no proceedings
                  for that purpose have been instituted or, to the Company's
                  knowledge, threatened; and

                           (iii) since the date of the most recent financial
                  statements included in the Prospectus (exclusive of any
                  supplement thereto), there has been no material adverse effect
                  on the condition (financial or otherwise), prospects,
                  earnings, business or properties of the Company and its
                  Subsidiaries, taken as a whole, whether or not arising from
                  transactions in the ordinary course of business, except as set
                  forth in or contemplated in the Prospectus (exclusive of any
                  supplement thereto).

                  (g) At the Execution Time and at the Closing Date, Deloitte &
         Touche LLP shall have furnished to the Representatives a letter or
         letters, dated respectively as of the Execution Time and as of the
         Closing Date, in form and substance satisfactory to the
         Representatives, addressed to the Representatives, confirming that they
         are independent accountants within the meaning of the Act and the
         applicable published rules and regulations thereunder and stating in
         effect that:

                           (i) in their opinion the consolidated financial
                  statements and financial statement schedules audited by them
                  and included in the Registration Statement and the Prospectus
                  and reported on by them comply as to form in all material
                  respects with the applicable accounting requirements of the
                  Act and the related published rules and regulations;

                           (ii) based upon a reading of the latest unaudited
                  consolidated financial statements made available by the
                  Company; their limited review in accordance with the standards
                  established by the American Institute of Certified Public
                  Accountants ("AICPA") of the unaudited interim financial
                  information for the date covered by such financial statements
                  for the period; carrying out certain specified procedures (but
                  not an examination in accordance with generally accepted
                  auditing standards) which would not necessarily reveal matters
                  of significance with respect to the comments set forth in such
                  letter; such specified procedures would 


                                       17

<PAGE>


                  include, but are not limited to, a reading of minutes of the
                  shareholders' and directors' meetings (and any meetings of
                  committees of the Board of Directors) of the Company and its
                  Subsidiaries; and inquiries of certain officials of the
                  Company who have responsibility for financial and accounting
                  matters of the Company and Subsidiaries as to transactions and
                  events subsequent to December 31, 1997, nothing has come to
                  their attention that causes them to believe that:

                                    (1) any unaudited financial statements
                           included in the Registration Statement and the
                           Prospectus do not comply as to form in all material
                           respects with applicable accounting requirements of
                           the Act and with the published rules and regulations
                           of the Commission with respect to registration
                           statements on Form S-1; and said unaudited financial
                           statements are not in conformity with generally
                           accepted accounting principles applied on a basis
                           substantially consistent with that of the audited
                           financial statements included in the Registration
                           Statement and the Prospectus;

                                    (2) with respect to the period subsequent to
                           December 31, 1997, there were any changes, at a
                           specified date not more than five days prior to the
                           date of the letter, in the long-term debt of the
                           Company and its Subsidiaries or capital stock of the
                           Company or decreases in the stockholders' equity of
                           the Company as compared with the amounts shown on the
                           December 31, 1997 consolidated balance sheet included
                           in the Registration Statement and the Prospectus, or
                           for the period from January 1, 1998 to such specified
                           date there were any decreases, as compared with the
                           corresponding period in the preceding year in revenue
                           or per share amounts of net income of the Company and
                           its Subsidiaries, except in all instances for changes
                           or decreases set forth in such letter, in which case
                           the letter shall be accompanied by an explanation by
                           the Company as to the significance thereof unless
                           said explanation is not deemed necessary by the
                           Representatives; or

                                    (3) the information included in the
                           Registration Statement and Prospectus in response to
                           Regulation S-K, Item 301 (Selected Financial Data)
                           and Item 402 (Executive Compensation) is not in
                           conformity with the applicable disclosure
                           requirements of Regulation S-K; and

                           (iii) they have performed certain other specified
                  procedures as a result of which they determined that certain
                  information of an accounting, financial or statistical nature
                  (which is limited to accounting, financial or statistical
                  information derived from the general accounting records of the
                  Company and its Subsidiaries) set forth in the Registration
                  Statement and the Prospectus, including the information set
                  forth under the captions "Prospectus Summary", "Risk Factors",
                  "Use of Proceeds",
                                       18

                  and Operating Data", "Management's Discussion and Analysis of
                  Financial Conditions and Results of Operations", "Business",
                  "Management", and "Certain Relationships and Related
                  Transactions" in the Prospectus, agrees with the accounting
                  records of the Company and its Subsidiaries, excluding any
                  questions of legal interpretation.

                  References to the Prospectus in this paragraph (g) include any
                  supplement thereto at the date of the letter.

                  The Company shall have received from Deloitte & Touche LLP
         (and furnished to the Representatives) a report with respect to a
         review of unaudited interim financial information of the Company for
         the four quarters ending December 31, 1997, in accordance with
         Statement on Auditing Standards No. 71.

                  (h) Subsequent to the Execution Time or, if earlier, the dates
         as of which information is given in the Registration Statement
         (exclusive of any amendment thereof) and the Prospectus (exclusive of
         any supplement thereto), there shall not have been (i) any change or
         decrease specified in the letter or letters referred to in paragraph
         (g) of this Section 6 or (ii) any change, or any development involving
         a prospective change, in or affecting the condition (financial or
         otherwise), earnings, business or properties of the Company and its
         Subsidiaries taken as a whole, whether or not arising from transactions
         in the ordinary course of business, except as set forth in or
         contemplated in the Prospectus (exclusive of any supplement thereto)
         the effect of which, in any case referred to in clause (i) or (ii)
         above, is, in the sole judgment of the Representatives, so material and
         adverse as to make it impractical or inadvisable to proceed with the
         offering or delivery of the Securities as contemplated by the
         Registration Statement (exclusive of any amendment thereof) and the
         Prospectus (exclusive of any supplement thereto).

                  (i) The Securities shall have been listed and admitted and
         authorized for trading on the Nasdaq National Market upon issuance.

                  (j) At the Execution Time, the Company shall have furnished to
         the Representatives a letter substantially in the form of Exhibit A
         hereto from each officer and director of the Company and major
         shareholders listed in Schedule II hereto addressed to the
         Representatives.

                  (k) Prior to the Closing Date, the Company shall have
         furnished to the Representatives such further information, certificates
         and documents as the Representatives may reasonably request.

                  If any of the conditions specified in this Section 6 shall not
have been fulfilled in all material respects when and as provided in this
Agreement, or if any of the opinions and certificates mentioned above or
elsewhere in this Agreement shall not be in all material respects reasonably
satisfactory in form and substance to the Representatives and counsel for the
Underwriters, this Agreement and all obligations of the

                                       19

<PAGE>

Underwriters hereunder may be canceled at, or at any time prior to, the Closing
Date by the Representatives. Such cancellation shall not effect any liability on
the part of the Company for a breach hereunder or otherwise. Notice of such
cancellation shall be given to the Company in writing or by telephone or
facsimile confirmed in writing.

                  The documents required to be delivered by this Section 6 shall
be delivered at the office of Paul, Hastings, Janofsky & Walker LLP, counsel for
the Underwriters, at 399 Park Avenue, New York, New York, on the Closing Date.

                  7. Reimbursement of Underwriters' Expenses. If the sale of the
Securities provided for herein is not consummated because any condition to the
obligations of the Underwriters set forth in Section 6 hereof is not satisfied,
because of any termination pursuant to Section 10 hereof or because of any
refusal, inability or failure on the part of the Company to perform any
agreement herein or comply with any provision hereof other than by reason of a
default by any of the Underwriters, the Company will reimburse the Underwriters
severally through Salomon Smith Barney on demand for all out-of-pocket expenses
(including reasonable fees and disbursements of counsel) that shall have been
incurred by them in connection with the proposed purchase and sale of the
Securities.

                  8. Indemnification and Contribution. (a) The Company agrees to
indemnify and hold harmless each Underwriter, the directors, officers, employees
and agents of each Underwriter and each person who controls any Underwriter
within the meaning of either the Act or the Exchange Act against any and all
losses, claims, damages or liabilities, joint or several, to which they or any
of them may become subject under the Act, the Exchange Act or other Federal or
state statutory law or regulation, at common law or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement of a
material fact contained in the registration statement for the registration of
the Securities as originally filed or in any amendment thereof, or in any
Preliminary Prospectus or the Prospectus, or in any amendment thereof or
supplement thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and agrees to reimburse
each such indemnified party, as incurred, for any legal or other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability or action; provided, however, that the
Company will not be liable in any such case to the extent that any such loss,
claim, damage or liability arises out of or is based upon any such untrue
statement or alleged untrue statement or omission or alleged omission made
therein in reliance upon and in strict conformity with written information
furnished to the Company by or on behalf of any Underwriter through the
Representatives specifically for inclusion therein. This indemnity agreement
will be in addition to any liability which the Company may otherwise have.

                  (b) Each Underwriter severally and not jointly agrees to
indemnify and hold harmless the Company, each of its directors, each of its
officers who signs the Registration Statement, and each person who controls the
Company within the meaning of either the Act or the Exchange Act, to the same
extent as the foregoing indemnity to each Underwriter, but only with reference
to written information relating to such Underwriter furnished to the Company by
or on behalf of such



                                       20

<PAGE>

Underwriter through the Representatives specifically for inclusion in the
documents referred to in the foregoing indemnity. This indemnity agreement will
be in addition to any liability which any Underwriter may otherwise have. The
Company acknowledges that the statements set forth in the last paragraph of the
cover page regarding delivery of the Securities, the legend in block capital
letters on page 2 related to stabilization, syndicate covering transactions and
penalty bids and, under the heading "Underwriting," (i) the sentences related to
concessions and reallowances and (ii) the paragraph related to stabilization,
syndicate covering transactions and penalty bids in any Preliminary Prospectus
and the Prospectus, constitute the only information furnished in writing by or
on behalf of the several Underwriters for inclusion in any Preliminary
Prospectus or the Prospectus.

                  (c) Promptly after receipt by an indemnified party under this
Section 8 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying party
under this Section 8, notify the indemnifying party in writing of the
commencement thereof; but the failure so to notify the indemnifying party (i)
will not relieve it from liability under paragraph (a) or (b) above unless and
to the extent it did not otherwise learn of such action and such failure results
in the forfeiture by the indemnifying party of substantial rights and defenses
and (ii) will not, in any event, relieve the indemnifying party from any
obligations to any indemnified party other than the indemnification obligation
provided in paragraph (a) or (b) above. The indemnifying party shall be entitled
to appoint counsel of the indemnifying party's choice at the indemnifying
party's expense to represent the indemnified party in any action for which
indemnification is sought (in which case the indemnifying party shall not
thereafter be responsible for the fees and expenses of any separate counsel
retained by the indemnified party or parties except as set forth below);
provided, however, that such counsel shall be satisfactory to the indemnified
party. Notwithstanding the indemnifying party's election to appoint counsel to
represent the indemnified party in an action, the indemnified party shall have
the right to employ separate counsel (including local counsel), and the
indemnifying party shall bear the reasonable fees, costs and expenses of such
separate counsel if (i) the use of counsel chosen by the indemnifying party to
represent the indemnified party would present such counsel with a conflict of
interest, (ii) the actual or potential defendants in, or targets of, any such
action include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be legal
defenses available to it and/or other indemnified parties which are different
from or additional to those available to the indemnifying party, (iii) the
indemnifying party shall not have employed counsel satisfactory to the
indemnified party to represent the indemnified party within a reasonable time
after notice of the institution of such action or (iv) the indemnifying party
shall authorize the indemnified party to employ separate counsel at the expense
of the indemnifying party. An indemnifying party will not, without the prior
written consent of the indemnified parties, settle or compromise or consent to
the entry of any judgment with respect to any pending or threatened claim,
action, suit or proceeding in respect of which indemnification or contribution
may be sought hereunder (whether or not the indemnified parties are actual or
potential parties to such claim or action) unless such settlement, compromise or
consent includes an unconditional release of each indemnified party from all
liability arising out of such claim, action, suit or proceeding.

                  (d) In the event that the indemnity provided in paragraph (a)
or (b) of this Section 8 is unavailable to or insufficient to hold harmless an
indemnified party for any reason, the Company and the Underwriters severally
agree to contribute to the aggregate losses, claims, damages and liabilities
(including legal or other expenses reasonably incurred in connection with
investigating or defending same) (collectively "Losses") to which the Company
and one or more of the Underwriters may be subject in such proportion as is
appropriate to reflect the relative benefits received by the Company on the one
hand and by the Underwriters on the other from the offering of the Securities;
provided, however, that in no case shall any Underwriter (except as may be
provided in any agreement among underwriters relating to the offering of the
Securities) be responsible for any amount in excess of the underwriting discount
or commission applicable to the Securities purchased by such Underwriter
hereunder. If the allocation provided by the immediately preceding sentence is
unavailable for any reason, the Company and the Underwriters severally shall
contribute in such proportion as is appropriate to reflect not only such
relative benefits but also the relative fault of the Company on the one hand and
of the Underwriters on the other in connection with the statements or omissions
which resulted in such Losses as well as any other relevant equitable
considerations. Benefits received by the Company shall be deemed to be equal to
the total net proceeds from the offering (before deducting expenses) received by
it, and benefits received by the Underwriters shall be deemed to be equal to the
total underwriting discounts and commissions, in each case as set forth on the
cover page of the Prospectus. Relative fault shall be determined by reference
to, among other things, whether any untrue or any alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact
relates to information provided by the Company on the one hand or the
Underwriters on the other, the intent of the parties and their relative
knowledge, access to information and opportunity to correct or prevent such
untrue statement or omission. The Company and the Underwriters agree that it
would not be just and equitable if contribution were determined by pro rata
allocation or any other method of allocation which does not take account of the
equitable considerations referred to above. Notwithstanding the provisions of
this paragraph (d), no person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation. For purposes of
this Section 8, each person who controls an Underwriter within the meaning of
either the Act or the Exchange Act and each director, officer, employee and
agent of an Underwriter shall have the same rights to contribution as such
Underwriter, and each person who controls the Company within the meaning of
either the Act or the Exchange Act, each officer of the Company who shall have
signed the Registration Statement and each director of the Company shall have
the same rights to contribution as the Company, subject in each case to the
applicable terms and conditions of this paragraph (d).

                  9. Default by an Underwriter. If any one or more Underwriters
shall fail to purchase and pay for any of the Securities agreed to be purchased
by such Underwriter or Underwriters hereunder and such failure to purchase shall
constitute a default in the performance of its or their obligations under this
Agreement, the remaining Underwriters shall be obligated severally to take up
and pay for (in the respective proportions which the amount of Securities set
forth opposite their names in Schedule I hereto bears to the aggregate amount of
Securities set forth opposite the names of all the remaining Underwriters) the
Securities which the defaulting

                                       22

<PAGE>


Underwriter or Underwriters agreed but failed to purchase; provided, however,
that in the event that the aggregate amount of Securities which the defaulting
Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of
the aggregate amount of Securities set forth in Schedule I hereto, the remaining
Underwriters shall have the right to purchase all, but shall not be under any
obligation to purchase any, of the Securities, and if such nondefaulting
Underwriters do not purchase all the Securities, this Agreement will terminate
without liability to any nondefaulting Underwriter or the Company. In the event
of a default by any Underwriter as set forth in this Section 9, the Closing Date
shall be postponed for such period, not exceeding five Business Days, as the
Representatives shall determine in order that the required changes in the
Registration Statement and the Prospectus or in any other documents or
arrangements may be effected. Nothing contained in this Agreement shall relieve
any defaulting Underwriter of its liability, if any, to the Company and any
nondefaulting Underwriter for damages occasioned by its default hereunder.

                  10. Termination. This Agreement shall be subject to
termination in the absolute discretion of the Representatives, by notice given
to the Company prior to delivery of and payment for the Securities, if at any
time prior to such time (i) trading in the Company's Common Stock shall have
been suspended by the Commission or the Nasdaq National Market or trading in
securities generally on the New York Stock Exchange or the Nasdaq National
Market shall have been suspended or limited or minimum prices shall have been
established on such Exchange or National Market, (ii) a banking moratorium shall
have been declared either by Federal or New York State authorities or (iii)
there shall have occurred any outbreak or escalation of hostilities, declaration
by the United States of a national emergency or war or other calamity or crisis
the effect of which on financial markets is such as to make it, in the sole
judgment of the Representatives, impractical or inadvisable to proceed with the
offering or delivery of the Securities as contemplated by the Prospectus
(exclusive of any supplement thereto).

                  11. Representations and Indemnities to Survive. The respective
agreements, representations, warranties, indemnities and other statements of the
Company or its officers and of the Underwriters set forth in or made pursuant to
this Agreement will remain in full force and effect, regardless of any
investigation made by or on behalf of any Underwriter or the Company or any of
the officers, directors or controlling persons referred to in Section 8 hereof,
and will survive delivery of and payment for the Securities. The provisions of
Sections 7 and 8 hereof shall survive the termination or cancellation of this
Agreement.

                  12. Notices. All communications hereunder will be in writing
and effective only on receipt, and, if sent to the Representatives, will be
mailed, delivered or telefaxed to the Salomon Smith Barney General Counsel (fax
no.: (212) ) and confirmed to the General Counsel, Salomon Smith Barney, at ,
New York, New York, , Attention: General Counsel; or, if sent to the Company,
will be mailed, delivered or telefaxed to (704) 319-1345 and confirmed to it at
212 South Tryon Street, Suite 1540, attention of Tansukh V. Ganatra.

                  13. Successors. This Agreement will inure to the benefit of
and be binding upon the parties hereto and their respective successors and the
officers and 

                                       23

<PAGE>


directors and controlling persons referred to in Section 8 hereof, and no other
person will have any right or obligation hereunder.

                  14. Applicable Law. This Agreement will be governed by and
construed in accordance with the laws of the State of New York applicable to
contracts made and to be performed within the State of New York.

                  15. Counterparts. This Agreement may be signed in one or more
counterparts, each of which shall constitute an original and all of which
together shall constitute one and the same agreement.

                  16. Headings. The section headings used herein are for

Ladies and Gentlemen:

                  This letter is being delivered to you in connection with the
proposed Underwriting Agreement (the "Underwriting Agreement"), between US LEC
Corp., a Delaware corporation (the "Company"), and each of you as
representatives of a group of Underwriters named therein, relating to an
underwritten public offering of Class A Common Stock, $.01 par value (the
"Common Stock"), of the Company.

                  In order to induce you and the other Underwriters to enter
into the Underwriting Agreement, the undersigned will not, without the prior
written consent of Smith Barney Inc., offer, sell, contract to sell, pledge or
otherwise dispose of, or file (or participate in the filing of) a registration
statement with the Securities and Exchange Commission in respect of, or
establish or increase a put equivalent position or liquidate or decrease a call
equivalent position within the meaning of Section 16 of the Securities Exchange
Act of 1934, as amended, and the rules and regulations of the Securities and
Exchange Commission promulgated thereunder with respect to, any shares of
capital stock of the Company or any securities convertible into or exercisable
or exchangeable for such capital stock, or publicly announce an intention to
effect any such transaction, for a period of 180 days after the date of this
Agreement.

                  If for any reason the Underwriting Agreement shall be
terminated prior to the Closing Date (as defined in the Underwriting Agreement),
the agreement set forth above shall likewise be terminated.

                                Yours very truly,

                               _____________, 1998


Smith Barney Inc.
Bear, Stearns & Co. Inc.
Wheat First Securities, Inc.
As Representatives of the several Underwriters
c/o Smith Barney Inc.
388 Greenwich Street
New York, New York  10013

Ladies and Gentlemen:

         We have acted as special U.S. telecommunications regulatory counsel to
US LEC Corp., a Delaware corporation (the "Company"), and its subsidiaries
(collectively, the "Subsidiaries"). This opinion is being delivered to you
pursuant to Section 6(c) of the Underwriting Agreement dated ________, 1998
("Underwriting Agreement") entered into by the Company, Smith Barney Inc., Bear,
Stearns & Co. Inc., and Wheat First Securities, Inc., for themselves and the
other several Underwriters named in Schedule I to the Underwriting Agreement
(collectively the "Underwriters"). Each capitalized term used but not defined
herein shall have the meaning ascribed to it in the Underwriting Agreement.

         Our opinion is limited to certain U.S. telecommunications regulatory
matters specifically related to the Communications Act of 1934, as amended,
including amendments made by the Telecommunications Act of 1996, 47 U.S.C. ss.
151 et seq., and the rules, regulations and orders of the Federal Communications
Commission ("FCC") (collectively the "Communications Act"). We express no
opinion and assume no responsibility as to the applicability of any other U.S.,
state, local, foreign, supranational, or regional laws or regulations,
including, but not limited to, laws governing the corporate organization,
authority to transact business, or tax liability of the Company or the
Subsidiaries.

         In this limited capacity, and for the purposes of this opinion, we have
reviewed sections of the Company's Registration Statement on Form S-1
(Registration No. 333-46341) under the captions "Risk Factors-Competition,"
"Risk Factors-Risks Associated with Implementation of Growth
Strategy-Interconnection Agreements," "Risk Factors-Uncertainties Related to
Reciprocal Compensation," "Risk Factors-Regulation," "Business-US LEC's
Network-Interconnection," "Business-Competition,"
"Business-Regulation-Overview," "Business-Regulation-Federal Legislation,"
"Business-Regulation-Federal Regulation and Related Proceedings,"
"Business-Regulation-Eighth Circuit Court of Appeals Decision,"
"Business-Regulation-U.S. District Court Decision," and "Business-Legal
Proceedings."

         Although we have acted as special U.S. telecommunications regulatory
counsel in specific telecommunications regulatory matters to the Company and the
Subsidiaries, we draw your attention to the fact that we have not undertaken any
on-site or other physical inspections of their business or properties, and with
respect to business practices, operations, accounts, personnel or day-to-day
affairs have not independently verified the manner in which their respective
businesses are operated.

         For purposes of this opinion, we have reviewed the Underwriting
Agreement, the Prospectus, the certificate of the officers of the Company and
the Subsidiaries attached as Schedule A hereto (the "Certificate"), Licenses and
such documents as we have deemed necessary or appropriate to form


<PAGE>

the basis for the opinions hereinafter expressed. In our review, we have assumed
without independent investigation (i) the genuineness of all signatures; (ii)
that where any signature purports to have been made in a corporate,
governmental, fiduciary, or other capacity, the person who affixed such
signature to such document had authority to do so; (iii) the authenticity of all
documents submitted to us as originals; (iv) the conformity to authentic
original documents of all documents submitted to us as certified, conformed, or
photostatic copies; and (v) the conformity of all provisions, terms, and
conditions contained in documents submitted to us in draft form with the
provisions, terms, and conditions contained in the executed final versions of
such documents. We have also assumed, without independent inquiry, that there
are no agreements or understandings between or among the Company and other
parties other than those disclosed in the Underwriting Agreement that would
expand, modify, or otherwise affect the terms of the Underwriting Agreement or
the rights or obligations thereunder of the parties thereto, and that those
documents accurately and completely set forth the agreement of all parties
thereto.

         In connection with this opinion as to matters of fact, other than
factual matters relating to the existence of the Communications Act, we have
relied upon the representations and warranties of the Company and the Company's
officers set out in the Underwriting Agreement and the Certificate. We have not
undertaken any independent investigation to verify any such matters, and our
opinion is therefore, as to such factual matters, based solely upon such
representations and warranties. Whenever in this opinion we limit our opinion to
"to our knowledge," our statements are based solely on the Certificate and any
information that became known to the telecommunications attorneys of this firm
who are involved in representing the Company and the Subsidiaries in the course
of their performance of such representation, and a review of the publicly
available files of the FCC. Wherever in our opinion we state that the Company
and the Subsidiaries have filed a tariff at the FCC, we express no opinion
whatsoever concerning whether, and to what extent, such tariff reflects their
current actual rates and services or complies with the specific format, rate
structure, and other tariff rules of the FCC (except as expressly provided in
paragraph 5, below).

         For purposes of this opinion, we have made such examination of the
Communications Act as we have deemed necessary. In the course of developing this
opinion, we have examined only actions and approvals arising out of, relating
to, or taken pursuant to the provisions of the Communications Act. We have not
undertaken to determine the existence of any actions, approvals, or proceedings,
whether outstanding, pending, or threatened, before persons or entities other
than the FCC.

         This opinion is given as of the date hereof, and we assume no
obligation to notify you of any changes in this opinion as a result of any facts
that may come to our attention in the future, nor do we assume any obligation to
update or supplement this opinion to reflect any facts or circumstances which
may hereafter occur or come to our attention, or to assess the likelihood of any
event, including any proceeding or appeal which hereafter may be initiated by or
before the FCC, or any federal or state court or government agency, or any
changes in laws, rules or regulations, or the interpretation of such, which may
hereafter occur, or of any material changes in the terms of the transactions
contemplated in the Underwriting Agreement.

         On the basis of the foregoing, and subject to the assumptions,
limitations and exceptions set forth herein, we are of the opinion that:

1.       Schedule B hereto accurately and completely lists all of the
         certificates and authorizations of the Company and the Subsidiaries
         issued by the FCC. Each of the Company and its Subsidiary have the
         certificates and authorizations, if any, required by the Communications
         Act (collectively the "Licenses") for the provision of interstate and
         foreign

<PAGE>


         telecommunications services within the United States as described in
         the Registration Statement.

2.       To our knowledge, neither the Company nor any of the Subsidiaries are
         subject to any pending or threatened complaint, investigation or
         proceeding before the FCC based on any alleged violation by the Company
         or any Subsidiary in connection with its provision of or failure to
         provide telecommunications service.

3.       To our knowledge, (i) the Licenses are validly issued; (ii) the
         Licenses are in full force and effect and are not subject to conditions
         outside the ordinary course; and (iii) all express conditions in the
         Licenses have been satisfied.

4.       The statements in the Registration Statement and Prospectus under the
         heading of "Risk Factors-Competition,""Risk Factors-Risks Associated
         with Implementation of Growth Strategy-Interconnection Agreements,"
         "Risk Factors-Uncertainties Related to Reciprocal Compensation," "Risk
         Factors-Regulation," "Business-US LEC's Network- Interconnection,"
         "Business-Competition," "Business-Regulation-Overview,"
         "Business-Regulation-Federal Legislation," "Business-Regulation-Federal
         Regulation and Related Proceedings," "Business -Regulation-Eighth
         Circuit Court of Appeals Decision," "Business-Regulation-U.S. District
         Court Decision," and "Business-Legal Proceedings" insofar as such
         statements constitute a summary of the legal matters, documents or
         proceedings of the FCC with respect to telecommunications matters
         referred to therein, are accurate in all material respects, and fairly
         summarize the matters therein described.

5.       All regulatory tariffs applicable to the Company's and the
         Subsidiaries' interexchange, exchange access, and international
         operations, (the "FCC Tariffs") are in full force and effect in
         accordance with their terms, and to our knowledge, there is no
         outstanding notice of suspension, cancellation or termination or any
         threatened suspension, cancellation or termination with respect to any
         of the FCC Tariffs. Each of the Company and the Subsidiaries are not
         subject to any restrictions or conditions applicable to its FCC Tariffs
         that limit or would limit the operations of the Company and the
         Subsidiaries (other than restrictions or conditions generally
         applicable to tariffs of that type). Each such FCC Tariff has been
         accepted by the FCC. To our knowledge, the Company and the Subsidiaries
         are not in violation under the terms and conditions of the FCC Tariffs.

6.       The Company and the Subsidiaries have the consents or approvals, if
         any, of the FCC, and have made any necessary or required filings,
         required for the consummation of the transactions contemplated in the
         Underwriting Agreement.

7.       Neither the execution and delivery of the Underwriting Agreement by the
         Company nor the performance by the Company of its obligations under the
         Underwriting Agreement will violate the Communications Act.

8.       Based upon a review of public files of the FCC, appropriate files of
         this firm and an inquiry of lawyers in this firm who have substantial
         responsibility for the Company's and the Subsidiaries' legal matters
         handled by this firm, we confirm that except as disclosed in the
         Underwriting Agreement: (a) there is no unsatisfied adverse FCC order,
         decree or ruling outstanding against the Company or any Subsidiary or
         any of the Licenses; (b) none of the Company or any Subsidiary is a
         party to any complaint, action or other proceeding at the FCC,
         including complaints against other licensees or applicants; (c)
         Schedule B hereto includes all applications on behalf of the
         Company or any Subsidiary or with respect to the Licenses that are now
         pending before the FCC; and (d) the Company and the Subsidiaries

<PAGE>


         have not been the subject of any final adverse order, decree or ruling
         of the FCC (including any notice of forfeiture which has been paid).

         No facts have come to the attention of those attorneys in the Firm who
regularly render service on behalf of the Company and the Subsidiaries to cause
us to believe, and we have no reason to believe, that both as of the Effective
Date and as of the Closing Date, the statements in the Registration Statement
and the Prospectus under the captions "Risk Factors-Risks Associated with
Implementation of Growth Strategy-Interconnection Agreements," "Risk
Factors-Uncertainties Related to Reciprocal Compensation," "Risk
Factors-Regulation," "Business-US LEC's Network - Interconnection,"

"Business-Regulation-Federal Legislation," "Business-Regulation-Federal
Regulation and Related Proceedings," "Business -Regulation-Eighth Circuit Court
of Appeals Decision," "Business-Regulation-U.S. District Court Decision," and
"Business - Legal Proceedings" that pertain to the Communications Act, contained
or contains any untrue statement of a material fact or omitted or omits to state
a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances in which they were made, not
misleading.

         The opinions expressed in this letter are subject in all respects to
the following additional qualifications: (a) this opinion addresses only the
transactions that are being consummated on the date hereof and does not address
any transaction that may take place after the Closing Date; (b) any action that
would transfer DE FACTO (actual) or DE JURE (legal) control of the Company is
subject to the requirement for prior approval from the FCC; (c) no opinion is
rendered as to matters not specifically referred to herein or as to any fact or
circumstance that hereafter may come to our attention or any change in law that
hereafter may occur, and under no circumstances are you to infer from anything
stated or not stated herein any opinion with respect to such matters; (d) all
opinions expressed in this letter are limited solely to the effect of the
Communications Act as presently in effect on the telecommunications business of
the Company and the Subsidiaries, and we express no opinion as to the effect of
any other federal, state, local, foreign, supranational or regional statute or
equitable doctrine or common law or of the regulations of any other agency or
administrative body; (e) other than as expressly stated in numbered paragraphs
one (1) through (8), no opinion is rendered as to the compliance of the Company
and the Subsidiaries in the past or in the future with any or all conditions or
other requirements of the FCC contained in the orders, if any, authorizing the
operations of the Company and the Subsidiaries or otherwise imposed by statute,
rule, regulation or policy, and we assume no obligation to ensure that the
Company or any Subsidiary complies with such conditions or requirements; (f) we
express no opinion as to the effect of any failure by the Company and the
Subsidiaries to comply with any conditions or requirements of the FCC; and (g)
we express no opinion with respect to any parties or entities other than the
Company and the Subsidiaries.

         This opinion is given solely for the benefit of, and may be relied upon
only by, the Underwriters. No other person has the right to rely upon it, nor
may it be quoted, used, relied upon, redelivered, or referred to by any
governmental agency or any other person or entity, without the prior written
consent of this firm.

Wheat First Securities, Inc.
As Representatives of the several Underwriters
c/o Smith Barney Inc.
388 Greenwich Street
New York, New York  10013

Ladies and Gentlemen:


         We have acted as special [State] telecommunications regulatory counsel
to US LEC Corporation of ___________, a [State] corporation (the "Company").
This opinion is being delivered to you pursuant to Section 6(d) of the
Underwriting Agreement dated ________, 1998 ("Underwriting Agreement") entered
into by U.S. LEC Corp., the parent corporation of the Company (the "Parent"),
Smith Barney Inc., Bear, Stearns & Co. Inc., and Wheat First Securities, Inc.,
for themselves and the other several Underwriters named in Schedule I to the
Underwriting Agreement (collectively the "Underwriters"). Each capitalized term
used but not defined herein shall have the meaning ascribed to it in the
Underwriting Agreement.

         Our opinion is limited to certain [State] telecommunications regulatory
matters specifically related to the statutes of [State] governing intrastate
telecommunications, and the rules, regulations and orders of [State Public
Utility Commission] (hereinafter, the "Commission") with primary regulatory
jurisdiction over intrastate telecommunications services of the Company
(collectively "State Telecommunications Laws"). We express no opinion and assume
no responsibility as to the applicability of any other U.S., state, local,
foreign, supranational, or regional laws or regulations, including, but not
limited to, laws governing the corporate organization, authority to transact
business, or tax liability of the Parent or the Company.

         In this limited capacity, and for the purposes of this opinion, we have
reviewed sections of the Parent's Registration Statement on Form S-1
(Registration No. 333-46341) filed by the Parent, under the captions "Risk
Factors-Competition," "Risk Factors-Risks Associated with Implementation of
Growth Strategy-Interconnection Agreements," "Risk Factors-Uncertainties Related
to Reciprocal Compensation," "Risk Factors-Regulation," "Business-US LEC's
Network-Interconnection," "Business-Regulation-State Regulation,"
"Business-Regulation-BellSouth North Carolina PUC Proceeding,"
"Business-Competition," and "Business-Legal Proceedings."

         Although we have acted as special [State] telecommunications regulatory
counsel in specific telecommunications regulatory matters to the Company, we
draw your attention to the fact that we have not undertaken any on-site or other
physical inspections of their business or properties, and with respect to
business practices, operations, accounts, personnel or day-to-day affairs have
not independently verified the manner in which their respective businesses are
operated.

         For purposes of this opinion, we have reviewed the Underwriting
Agreement, the Prospectus, the certificate of the officers of the Company
attached as Schedule A hereto (the "Certificate"), Licenses and such documents
as we have deemed necessary or appropriate to form the basis for the


<PAGE>


opinions hereinafter expressed. In our review, we have assumed without
independent investigation (i) the genuineness of all signatures; (ii) that where
any signature purports to have been made in a corporate, governmental,
fiduciary, or other capacity, the person who affixed such signature to such
document had authority to do so; (iii) the authenticity of all documents
submitted to us as originals; (iv) the conformity to authentic original
documents of all documents submitted to us as certified, conformed, or
photostatic copies; and (v) the conformity of all provisions, terms, and
conditions contained in documents submitted to us in draft form with the
provisions, terms, and conditions contained in the executed final versions of
such documents. We have also assumed, without independent inquiry, that there
are no agreements or understandings between or among the Parent or the Company
and other parties other than those disclosed in the Underwriting Agreement that
would expand, modify, or otherwise affect the terms of the Underwriting
Agreement or the rights or obligations thereunder of the parties thereto, and
that those documents accurately and completely set forth the agreement of all
parties thereto.

         In connection with this opinion as to matters of fact, other than
factual matters relating to the existence of the State Telecommunications Laws,
we have relied upon the representations and warranties of the Parent set out in
the Underwriting Agreement and by the Company's officers in the Certificate. We
have not undertaken any independent investigation to verify any such matters,
and our opinion is therefore, as to such factual matters, based solely upon such
representations and warranties. Whenever in this opinion we limit our opinion to
"to our knowledge," our statements are based solely on the Certificate and any
information that became known to the telecommunications attorneys of this firm
who are involved in representing the Company in the course of their performance
of such representation, and a review of the publicly available files of the
Commission. Wherever in our opinion we state that the Company has filed a tariff
at the Commission, we express no opinion whatsoever concerning whether, and to
what extent, such tariff reflects their current actual rates and services or
complies with the specific format, rate structure, and other tariff rules of the
Commission (except as expressly provided in paragraph 5, below).

         For purposes of this opinion, we have made such examination of the
State Telecommunications Laws as we have deemed necessary. In the course of
developing this opinion, we have examined only actions and approvals arising out
of, relating to, or taken pursuant to the provisions of the State
Telecommunications Laws. We have not undertaken to determine the existence of
any actions, approvals, or proceedings, whether outstanding, pending, or
threatened, before persons or entities other than the Commission.

         This opinion is given as of the date hereof, and we assume no
obligation to notify you of any changes in this opinion as a result of any facts
that may come to our attention in the future, nor do we assume any obligation to
update or supplement this opinion to reflect any facts or circumstances which
may hereafter occur or come to our attention, or to assess the likelihood of any
event, including any proceeding or appeal which hereafter may be initiated by or
before the Commission, or any federal or state court or government agency, or
any changes in laws, rules or regulations, or the interpretation of such, which
may hereafter occur, or of any material changes in the terms of the transactions
contemplated in the Underwriting Agreement.

         On the basis of the foregoing, and subject to the assumptions,
limitations and exceptions set forth herein, we are of the opinion that:

1.       Schedule B hereto accurately and completely lists all of the
         certificates and authorizations of the Company in [specify State]. The
         Company has the certificates and authorizations, if any, required by
         the State Telecommunications Laws (collectively the "Licenses") for the
         provision of intrastate telecommunications services in [specify State]
         as described in the Registration Statement.



<PAGE>


2.       To our knowledge, the Company is not subject to any pending or
         threatened complaint, investigation or proceeding before the Commission
         based on any alleged violation by the Company in connection with its
         provision of or failure to provide telecommunications service.

3.       To our knowledge, (i) the Licenses are validly issued; (ii) the
         Licenses are in full force and effect and are not subject to conditions
         outside the ordinary course; and (iii) all express conditions in the
         Licenses have been satisfied.

4.       The statements in the Registration Statement and Prospectus under the
         heading of "Risk Factors-Competition,""Risk Factors-Risks Associated
         with Implementation of Growth Strategy-Interconnection Agreements,"
         "Risk Factors-Uncertainties Related to Reciprocal Compensation," "Risk
         Factors-Regulation," "Business-US LEC's Network-Interconnection,"
         "Business - Regulation - State Regulation,"
         "Business-Regulation-BellSouth North Carolina PUC Proceeding,"
         "Business-Competition," and "Business-Legal Proceedings" insofar as
         such statements constitute a summary of the legal matters, documents or
         proceedings of the Commission with respect to telecommunications
         matters referred to therein, are accurate in all material respects, and
         fairly summarize the matters therein described.

5.       All regulatory tariffs applicable to the Company's local exchange,
         and/or intrastate interexchange, and/or exchange access operations in
         [specify State] (the "State Tariffs") are in full force and effect in
         accordance with their terms, and to our knowledge, there is no
         outstanding notice of suspension, cancellation or termination or any
         threatened suspension, cancellation or termination with respect to any
         of the Company's State Tariffs. The Company is not subject to any
         restrictions or conditions applicable to its State Tariffs that limit
         or would limit the operations of the Company (other than restrictions
         or conditions generally applicable to Tariffs of that type). Each such
         Tariff has been accepted by the Commission. To our knowledge, the
         Company is not in violation under the terms and conditions of any such
         Tariffs.

6.       The Company has the consents or approvals, if any, of the Commission,
         and has made any necessary or required filings, required for the
         consummation of the transactions contemplated in the Underwriting
         Agreement.

7.       Neither the execution and delivery of the Underwriting Agreement by the
         Parent nor the performance by the Parent of its obligations under the
         Underwriting Agreement will violate the State Telecommunications Laws
         applicable to the Company.

8.       Based upon a review of public files of the Commission, appropriate
         files of this firm and an inquiry of lawyers in this firm who had
         substantial responsibility for the Company's legal matters handled by
         this firm, we confirm that, except as disclosed in the Underwriting
         Agreement: (a) there is no unsatisfied adverse Commission order, decree
         or ruling outstanding against the Company or any of the Licenses; (b)
         the Company is not a party to any complaint, action or other proceeding
         at the Commission, including complaints against other licensees or
         applicants; (c) Schedule B hereto includes all applications on
         behalf of the Company or with respect to the Licenses that are now
         pending before the Commission; and (d) the Company has not been the
         subject of any final adverse order, decree or ruling of the Commission
         (including any notice of forfeiture which has been paid).

         No facts have come to the attention of those attorneys in the Firm who
regularly render service on behalf of the Company to cause us to believe, and we
have no reason to believe, that both

"Business-Regulation-State Regulation," "Business-Regulation-BellSouth North

such conditions or requirements; (f) we express no opinion as to the effect of
any failure by the Company to comply with any conditions or requirements of the
Commission; and (g) we express no opinion with respect to any parties or
entities other than the Company.

only by, the Underwriters. No other person has the right to rely upon it, nor
