        THIS EMPLOYMENT AGREEMENT (the "AGREEMENT") is made as of this 4th day
of August 1999, by and between UNIVERSAL ACCESS, INC., a Delaware corporation
(the "COMPANY"), and Holly Weller (the "EMPLOYEE").

                                    RECITALS:

agree as follows:

                                    ARTICLE I

                                   EMPLOYMENT

        1.1 Employment. The Company hereby employs, engages, and hires Employee,
and Employee hereby accepts employment, upon the terms and conditions set forth
in this Agreement. The Employee shall serve as the Executive Vice President of
Marketing of the Company. The Employee shall have and fully perform the duties
and responsibilities required for such job title and position and to perform
such additional services and discharge such other responsibilities as may be,
from time to time, assigned or delegated by the Company.

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

Agreement and agrees to devote his or her full time and efforts to the faithful
and diligent performance of the services described herein, including the

<PAGE>   2
as the Company may, from time to time, stipulate. Without limiting the
generality of the foregoing, Employee shall devote not less than five (5) days
per week to this employment, and shall be present on the Company premises or
actively engaged in service to or on behalf of the Company during normal
business hours Monday through Friday, excluding periods of vacation and sick
leave.

                                   ARTICLE II

                                      TERM

        2.1 Term. The term of employment under this Agreement shall be one (1)
year (the "Initial Term"), commencing on the date of the Agreement. This
Agreement shall automatically renew for successive one year terms thereafter
(each a "Renewal Term") unless either party delivers notice of termination to
the other party not less than fifteen (15) days prior to the end of the Initial
Term or Renewal Term in question. The Initial Term and any Renewal Terms shall
herein be referred to as the "Employment Term".

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

       (a)  By the Company immediately for "Cause." For the purpose of this
            Agreement, "Cause" shall mean (i) conduct amounting to fraud,
            embezzlement, or illegal misconduct in connection with Employee's
            duties under this Agreement; (ii) the conviction of Employee by a
            court of proper jurisdiction of (or his or her written, voluntary
            and freely given confession to) a crime which constitutes a felony
            (other than a traffic violation) or an indictment that results in
            material injury to the Company's property, operation or reputation;
            (iii) the willful failure of Employee to comply with reasonable
            directions of the Company or any of the policies of the Company
            after (a) written notice is delivered to the Employee describing
            such willful failure and (b) Employee has failed to cure or take
            substantial steps to cure such willful failure after a reasonable
            time period as determined by the Company in its reasonable
            discretion (not to be less than 15 days) unless the Employee, after
            discussion with counsel, in good faith believes, that the directions
            of the Company (or its actions or inactions in response to the
            Employee's written notice) are illegal; or (iv) willful misconduct
            or a material default by the Employee in the performance or
            observance of any promise or undertaking of Employee under this
            Agreement, which willful misconduct or default has continued for a
            period of ten (10) business days after written notice thereof from
            the Company to the Employee.

       (b)  Automatically, without the action of either party, upon the death of
            Employee ("Death").

<PAGE>   3
       (c)  By either party upon the Total Disability of the Employee. The
            Employee shall be considered to have a Total Disability for purposes
            of this Agreement if he or she is unable by reason of accident or
            illness to substantially perform his or her employment duties, and
            is expected to be in such condition for periods totaling six (6)
            months (whether or not consecutive) during any period of twelve (12)
            months. The determination of whether a Total Disability has occurred
            shall be determined by the Company, in good faith, at its sole
            discretion. Nothing herein shall limit the Employee's right to
            receive any payments to which Employee may be entitled under any
            disability or employee benefit plan of the Company or under any
            disability or insurance policy or plan. During a period of
            disability prior to termination hereunder, Employee shall continue
            to receive his or her full compensation (including base salary and
            bonus) and benefits, subject to offset to the extent of any
            disability insurance payments received by the Employee pursuant to
            any disability insurance policy maintained by or paid for by the
            Company.

       (d)  By the Employee upon ten (10) business days notice to the Company
            for Good Reason, which notice shall state the reason for
            termination. For the purpose of this Agreement, "Good Reason" shall
            mean any "Change in Control" (as hereinafter defined) or any
            material failure by the Company to comply with the provisions of
            this Employment Agreement, including but not limited to, failure to
            timely pay any part of Employee's compensation (including salary or
            bonus) or provide the benefits contemplated herein, and which is not
            remedied by the Company within ten (10) business days after receipt
            by the Company of written notice thereof from Employee; provided,
            that if such default is of a nature that it cannot be reasonably
            cured within ten (10) day period (but is curable), then if the
            Company shall have commenced an attempt to cure such default within
            such ten (10) day period, the period to cure the default shall be
            extended until the earlier of the date which is forty-five (45) days
            after receipt of notice or the Company has failed to diligently
            continue its efforts in a reasonable manner to cure its default.

            For purposes hereof, the term "Change in Control" shall mean the
            occurrence of any of the following:

            (1) the Company: (a) consummates a merger or consolidation which
                results in the voting securities of the Company outstanding
                immediately prior thereto continuing to represent (either by
                remaining outstanding or by being converted into voting
                securities of the surviving entity) less than fifty percent
                (50%) of the total voting power represented by the voting
                securities of the Company of such surviving entity outstanding
                immediately after such merger or consolidation; and (b)
                following such
<PAGE>   4
                event, the successor entity fails to employ Employee as follows
                (hereinafter, the "Same Terms"): on substantially identical
                terms as are required per this Agreement for the remaining
                Employment Term, and the successor entity further continues to
                employ Employee in the same city and with job responsibilities
                of a level substantially equivalent to or greater than those
                presently in force and effect;

            (2) a plan of complete liquidation of the Company or an agreement
                for the sale or disposition by the Company of (in one
                transaction or a series of transactions) all or substantially
                all of the Company's assets is consummated, and following such
                event the successor entity (if any) fails to employ Employee on
                the Same Terms; or

            (3) Company consummates a plan of complete liquidation of the
                Company or an agreement for the sale or disposition (in one
                transaction or a series of transactions) by the Company of all
                or substantially all of the Company's assets, and following such
                event the successor entity (if any) fails to employ Employee on
                the Same Terms;

            provided, however, that a public offering of the stock of the
            Company irrespective of the amount of voting securities owned by
            present shareholders after such offering shall not be deemed to
            constitute a Change of Control; and provided further that if
            Employee agrees to be employed by a successor entity on the Same
            Terms and the successor entity fails to do so, a Change in Control
            shall be deemed to have occurred.

       (e)  By the Employee without Good Reason, and therefore in breach of this
            Agreement.

       (f)  By the Company other than for Cause, Death or Total Disability, in
            which event Employee's sole remedy and compensation as a result of
            such termination shall be as set forth in Section 2.4(c) below.

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

        2.4 Cessation of Compensation. In lieu of any severance under any
severance plan that the Company may then have in effect, and subject to (i) the
receipt of a full and unconditional release from Employee and (ii) any amounts
owed by the Employee to the Company under any
<PAGE>   5
contract, agreement or loan document entered into after the date hereof which
relates solely to his or her employment with the Company (including, but not
limited to, loans made by the Company to the Employee), the Company shall pay to
the Employee, and the Employee shall be entitled to receive, the following
amounts within thirty (30) days of the date of a termination of his or her
employment:

       (a)  Voluntary Termination/Cause/Expiration of Term. Upon (i) Employee
            terminating his or her employment without Good Reason as provided in
            Section 2.2(e), (ii) the expiration of the Employment Term because
            the Employee or the Company elects to not extend the Employment
            Term, or (iii) a termination of the Employment Term for Cause by the
            Company as provided in Section 2.2(a), the Employee shall be
            entitled to receive his or her or her base salary (which shall
            include any of his or her unused vacation pay for the year of such
            termination) and expense reimbursements solely through the date of
            termination.

       (b)  Death or Total Disability. Upon the termination of the Employment
            Term by reason of the Death or Total Disability of the Employee, the
            Employee (or, in the case of Death, his or her estate) shall be
            entitled to receive his or her base salary (which shall include any
            of his or her unused vacation pay for the year of such termination)
            and expense reimbursements solely through the date of termination.

       (c)  Involuntary. Upon the termination of the Employment Term:

            (1) by the Company for any reason other than Cause, Death or Total
                Disability, or

            (2) by the Employee for Good Reason,

            the Employee shall be entitled to receive in a lump sum the balance
            of his or her base salary for the lesser of the remaining term of
            the Employment Term (exclusive of any renewals of the then existing
            term) or a period of six (6) months (the "Severance Term"), together
            with prorated vacation pay and expense reimbursement through the
            date of termination. In addition, Employee shall be entitled to
            payment by the Company of the premiums for group health insurance
            coverage otherwise payable by Employee under the Consolidated
            Omnibus Budget Reconciliation Act of 1985 ("COBRA") for the
            Severance Term. It shall be a condition to Employee's right to
            receive the payments described above that Employee shall be in
            compliance with all of the Employee's obligations which survive
            termination hereof, including without limitation those arising under
            Articles IV and V hereof. The payments described above are intended
            to be in lieu of all other payments to which Employee might
<PAGE>   6
            otherwise be entitled in respect of termination of Employee's
            employment without Cause unless otherwise required by law or under
            other agreements between the parties. Notwithstanding anything to
            the contrary contained herein, to the extent Employee receives any
            direct or indirect compensation, consulting fees or health insurance
            from any Third Parties (as hereinafter defined) during the Severance
            Term or with respect to services performed during the Severance Term
            such compensation shall be credited dollar for dollar against the
            Severance Term payment obligations of Company under this Section
            2.4(c).

        2.5 Business Expenses.

       (a)  Reimbursement. The Company shall reimburse the Employee for all
            reasonable, ordinary, and necessary business expenses incurred by
            him or her in connection with the performance of his or her duties
            hereunder, including, but not limited to, ordinary and necessary
            travel expenses and entertainment expenses. The reimbursement of
            business expenses will be governed by the policies of the Company
            from time-to-time and the terms otherwise set forth herein.

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

        2.6 Sole Compensation. Employee shall not be entitled to any other
compensation from the Company than as set forth in Article II hereof as a result
of termination of Employee's employment.

                                   ARTICLE III

                            COMPENSATION AND BENEFITS

        3.1 Compensation. During the Employment Term of this Agreement, the
Company shall pay Employee such salary and bonus as set forth on Exhibit A.

<PAGE>   7
withholdings and deductions by the Company as are required by law. On
termination of the Employment Term, the Company shall be entitled to set off
against any monies owing by the Company to Employee the amount of any monies
owing from Employee to the Company.

        3.3 Other Benefits. Employee shall be entitled to participate in any
retirement, pension, profit-sharing, stock option, health plan, insurance,
disability income, incentive compensation and welfare or any other benefit plan
or plans of the Company which may now or hereafter be in effect and for which
the Employee is eligible. Notwithstanding the forgoing, the Company shall be
under no obligation to institute or continue the existence of any such benefit
plan.

                                   ARTICLE IV

           CONFIDENTIALITY, NON-SOLICITATION AND NON-COMPETE AGREEMENT

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

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

       (b)  Upon the termination of Employee's employment for any reason
            whatsoever, Employee shall deliver or cause to be delivered to the
            Company any and all Confidential Information or documents containing
            Confidential Information, including notes, drawings, notebooks,
            notes, records, keys, data and other documents and materials
<PAGE>   8
            belonging to the Company or its affiliates which is in his or her
            possession or under his or her control relating to the Company or
            its affiliates, regardless of the medium upon which it is stored,
            and will deliver to the Company upon such termination of employment
            any other property of the Company or its Affiliates which is in his
            or her possession or control.

        4.2 Non-Solicitation Covenant. Employee hereby covenants and agrees that
while employed by the Company and for a period of one (1) year following the
termination of Employee's employment with the Company for any reason, Employee
shall not (i) directly or indirectly, contact, solicit, interfere with, or
endeavor to entice away from the Company or its Affiliates any person, firm,
corporation, limited liability company or other entity that was a customer of
the Company at any time while Employee was an employee of the Company or its
Affiliates or who is a "prospective customer" of the Company, or (ii) induce,
attempt to induce or hire any employee (or any person who was an employee during
the year preceding the date of any solicitation) of the Company or its
Affiliates to leave the employ of the Company or its Affiliates, or in any way
interfere with the relationship between any such employee and the Company or its
Affiliates. For purposes hereof, "prospective customer" shall mean any person or
entity which has been solicited for business by Employee or any officer or other
employee of the Company during the one year period preceding the date of
termination of Employee's employment with the Company, or if Employee is still
employed by the Company within the one year period preceding the event in
question.

        4.3 Non-Competition Covenant. Employee acknowledges that the covenants
set forth in this Section 4.3 are reasonable in scope and essential to the
preservation of the Business of the Company (as defined herein). Employee also
acknowledges that the enforcement of the covenant set forth in this Section 4.3
will not preclude Employee from being gainfully employed in such manner and to
the extent as to provide a standard of living for himself or herself, the
members of his or her family and the others dependent upon Employee of at least
the level to which Employee and they have become accustomed and may expect. In
addition, Employee acknowledges that the Company has obtained an advantage over
its competitors as a result of its name, location and reputation that is
characterized by near permanent relationships with vendors, customers,
principals and other contacts which it has developed at great expense.
Furthermore, Employee acknowledges that competition by him or her following the
termination or expiration of his or her employment would impair the operation of
the Company beyond that which would arise from the competition of an unrelated
third party with similar skills. Employee hereby agrees that he or she shall
not, during his or her employment and for a period of one (1) year after the end
of his or her employment, directly or indirectly, engage in or become directly
or indirectly interested in any proprietorship, partnership, firm, trust,
company, limited liability company or other entity, other than the Company
(whether as owner, partner, trustee, beneficiary, stockholder, member, officer,
director, employee, independent contractor, agent, servant, consultant, lessor,
lessee or otherwise) that competes with the Company in the Business of the
Company in the Restricted Territory (as defined herein), other than owning an
interest in a
<PAGE>   9

company listed on a recognized stock exchange in an amount which does not exceed
five percent (5%) of the outstanding stock of such corporation. For purposes of
this Agreement, (i) the term "Business of the Company" shall include all
business activities and ventures related to providing telecommunications
services or products in which the Company is engaged, plans to engage in the
next twelve (12) months following termination of Employee's employment or has
engaged in during the prior twelve (12) months, as determined at any time during
the employment of the Employee; and (ii) the term "Restricted Territory" means
the geographical area consisting of a seventy mile radius surrounding each city
(and including such city) in which the Company maintains either an office or a
telecommunications facility.

        4.4 Remedies.

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

        6.2 Entire Agreement; Amendments, Etc. This Agreement contains the
entire agreement and understanding of the parties hereto, and supersedes all
prior agreements and understandings relating to the subject matter hereof.
Except as provided in Section 4.4(b), no modification, amendment, waiver or
alteration of this Agreement or any provision or term hereof shall in any event
be effective unless the same shall be in writing, executed by both parties
hereto, and any waiver so given shall be effective only in the specific instance

interest hereunder may not be assigned by Employee without the prior written
consent of the Company. No implication shall be drawn in favor or against either
party based upon the role of such party's counsel in the drafting of this

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