                                                                   Exhibit 10.10

                              EMPLOYMENT AGREEMENT

This Agreement is made and entered into as of the 1st day of August, 1999, by
and between APCOA/STANDARD PARKING, INC., a Delaware corporation, having offices
in Chicago, Illinois ("EMPLOYER"), and EDWARD E. SIMMONS of Calabasas,
California ("EMPLOYEE").

                                    RECITALS

       A.     Prior to the effective date hereof, Employee was providing
management services for Employer as an employee of D&E Parking, Inc. ("D&E"),
pursuant to the terms of that certain Executive Parking Management Agreement,
dated as of May 1, 1998, by and among Employer, D&E, Employee and Dale G. Stark,
as amended by that certain First Amendment of even date herewith (as so amended,
the "MANAGEMENT AGREEMENT"). Employer is in the business of operating private
and public parking facilities for itself, its subsidiaries, affiliates and
others, and acting as a consultant and/or manager for parking facilities
operated by others throughout the United States (Employer and its subsidiaries
and affiliates, and other Employer-controlled businesses engaged in parking
garage management (in each case including their predecessor's or successor's)
are referred to hereinafter as the "PARKING COMPANIES").

       B.     In the course of Employee's employment with D&E and hereunder,
Employee has had and will have access to highly confidential and proprietary
information of the Parking Companies and their clients, including without
limitation the information referred to in Paragraph V.

       C.     In addition to (and not in lieu of) Employee continuing to perform
his duties under the Management Agreement, Employer desires to employ Employee,
and Employee desires to be so employed, on and subject to the terms and
conditions hereinafter set forth.

       NOW, THEREFORE, in consideration of: (i) the foregoing premises, and;
(ii) the mutual covenants and agreements herein contained, including, but not
limited to, the agreement to arbitrate all disputes arising out of this
agreement, the Employer and Employee hereby covenant and agree as follows:

I.     PRIOR EMPLOYMENT EXPERIENCE/NO CONFLICT

Employee represents that Employee's employment hereunder will not violate any
agreement or obligation to any third party.

II.    AGREEMENT TO BE EMPLOYED - DUTIES/TITLE

Employer hereby employs Employee in the position of Chief Executive Officer of

perform duties in connection with Employee's employment as

                                       1

may be fixed from time to time by Employer. In the performance of his duties and
obligations under the Management Agreement and hereunder, Employee agrees to
faithfully and competently render Employee's services on a full-time basis, and
to devote Employee's best efforts and all of Employee's working time to the
business and affairs of Employer. Employee agrees to abide by the Code of
Business Conduct which has been or will be promulgated by Employer, and which
includes, but is not limited to, prohibitions on insider trading and the
disclosure of proprietary or confidential information. Employee acknowledges and
agrees that the last sentence of Section 2.3(a) of the Management Agreement
shall not be applicable to him during the Term of this Agreement. Instead,
Employee shall travel within and outside the Western Region, including without
limitation to Employer's headquarters in Chicago, Illinois, as often as may be
reasonably required by Employer and/or in order for Employee to properly perform
his duties hereunder.

III.   COMPENSATION

Employer shall compensate Employee for Employee's services during the Term of
this Agreement as follows:

       A.     SALARY/PERFORMANCE-BASED COMPENSATION.

              Employee shall receive a base salary of Seventeen Thousand Five
       Hundred Dollars ($17,500.00) per annum, payable in accordance with the
       payroll schedule of Employer as may be in effect from time to time during
       the term hereof. The salary shall be subject to periodic review and, in
       the sole discretion of Employer, may be adjusted upward without affecting
       any of the other provisions of this Agreement.

              In addition, Employee shall be eligible for annual
       performance-based compensation ("PBC") in addition to his salary, which
       will be based upon Employer's profitability and determined for fiscal
       year 1999, in accordance with the provisions set forth in Exhibit A
       attached hereto; provided, however, in no event will Employee's PBC for
       Compensation Year 1999 be less than fifty percent (50%) of the Target
       Amount (as specified and defined in Exhibit A). For fiscal years after
       1999, the PBC shall be in accordance with the PBC program then in effect
       or any replacement program adopted by Employer for operational Executive
       Vice Presidents of the Employer.

       B.     BUSINESS EXPENSES.

              Employee shall be reimbursed by Employer for those business
       expenses authorized by Employer or which are necessarily and reasonably
       incurred on behalf of Employer and which may properly be deducted by
       Employer as business expenses for tax purposes.

IV.    BENEFITS

       A.     HEALTH, DISABILITY AND LIFE INSURANCE.

              Employee shall be entitled to participate during the Term in any

                                       2
<Page>

       in the jurisdiction in which Employee is performing services for
       Employer, subject to the terms, conditions and eligibility restrictions
       set forth in such plans as from time to time in effect. The premiums for
       coverage shall be paid by Employer and Employee in such proportion as may
       be determined from time to time by Employer.

       B.     VACATIONS.

              Employee shall be entitled to receive vacations consistent with
       past practices under the Management Agreement.

       C.     OTHER BENEFITS.

              Employer shall provide Employee with other perquisites (for
       example, participation in Employer's 401(k) plan based upon Employee's
       base salary hereunder, and stock options in the event of a public
       offering) comparable to those being offered to other of Employer's
       Executive Vice Presidents. Employee acknowledges and agrees that during
       the Term, his right to receive such benefits shall be pursuant to this
       Agreement, and Section 4.3 of the Management Agreement shall not be
       applicable to him. Employer may, from time to time, provide other
       benefits to Employee. However, any such additional benefits shall be made
       available only at the discretion of Employer and may be withdrawn by
       Employer without incurring any obligations whatsoever to Employee for so
       doing.

V.     PROTECTION OF EMPLOYER ASSETS

       A.     TRADE SECRET AND CONFIDENTIAL INFORMATION.

              Employee recognizes and acknowledges that the acquisition and
       operation of, and the providing of consulting services for, parking
       facilities is a unique enterprise and that there are relatively few firms
       engaged in these businesses in the primary areas in which the Parking
       Companies operates. Employee further recognizes and acknowledges that as
       a result of employment with the Parking Companies, Employee has had and
       will continue to have access to confidential information and trade
       secrets of the Parking Companies that constitute proprietary information
       that the Parking Companies are entitled to protect, which information
       constitutes special and unique assets of the Parking Companies, including
       without limitation: (1) information relating to the Parking Companies'
       manner and methods of doing business, including without limitation,
       strategies for negotiating leases and management agreements; (2) the
       identity of the Parking Companies' clients, customers, lessors and
       locations, and the identity of any individuals or entities having an
       equity or other economic interest in any of the Parking Companies to the
       extent such identity has not otherwise been voluntarily disclosed by any
       of the Parking Companies; (3) the specific confidential terms of
       management agreements, leases or other business agreements, including
       without Limitation the duration of, and the fees, rent or other payments
       due thereunder; (4) the identities of beneficiaries under land trusts;
       (5) the business, developments, activities or systems of the Parking
       Companies, including without limitation any marketing or customer service
       oriented programs in the development stages or not otherwise known to the
       general public; (6) information

                                       3
<Page>

       concerning the business affairs of any individual or firm doing business
       with the Parking Companies; (7) financial data and the operating expense
       structure pertaining to any parking facility owned, operated, leased or
       managed by the Parking Companies or for which the Parking Companies have
       or are providing consulting services; and (8) other confidential
       information and trade secrets relating to the operation of the Employer's
       business (the matters described in this sentence hereafter referred to as
       the "Trade Secret and Confidential Information").

       B.     CUSTOMER RELATIONSHIPS.

              Employee understands and acknowledges that the Employer has
       expended significant resources over many years to identify, develop, and
       maintain its clients. Employee additionally acknowledges that the
       Employer's clients have had continuous and long-standing relationships
       with the Employer and that, as a result of these close, long-term
       relationships, the Employer possess significant knowledge of its clients
       and their needs. Finally, Employee acknowledges Employee's association
       and contact with these clients is derived solely from employment with the
       Employer. Employee further acknowledges that the Employer does business
       throughout the United States and that Employee personally has significant
       contact with the Employer customers solely as a result of his
       relationship with the Employer in the Western Region.

       C.     CONFIDENTIALITY.

              With respect to Trade Secret and Confidential Information, and
       except as may be required by the lawful order of a court of competent
       jurisdiction, Employee agrees that he shall:

              (1)    hold all Trade Secret and Confidential Information in
                     strict confidence and not publish or otherwise disclose any
                     portion thereof to any person whatsoever except with the
                     prior written consent of the Employer;

              (2)    use all reasonable precautions to assure that the Trade
                     Secret and Confidential Information are properly protected
                     and kept from unauthorized persons;

              (3)    make no use of any Trade Secret and Confidential
                     Information except as is required in the performance of his
                     duties for the Employer; and

              (4)    upon termination of his employment with the Employer,
                     whether voluntary or involuntary and regardless of the
                     reason or cause, or upon the request of the Employer,
                     promptly return to the Employer any and all documents, and
                     other things relating to any Trade Secret and Confidential
                     Information, all of which are and shall remain the sole
                     property of the Employer. The term "documents" as used in
                     the preceding sentence shall mean all forms of written or
                     recorded information and shall include, without limitation,
                     all accounts, budgets, compilations, computer records
                     (including, but not limited to, computer programs,
                     software, disks, diskettes or any other electronic or
                     magnetic storage media), contracts,

                                       4
<Page>

                     correspondence, data, diagrams, drawings, financial
                     statements, memoranda, microfilm or microfiche, notes,
                     notebooks, marketing or other plans, printed materials,
                     records and reports, as well as any and all copies,
                     reproductions or summaries thereof.

Notwithstanding the above, nothing contained herein shall restrict Employee from
using, at any time after the Employee's termination of employment with the
Employer, information which is in the public domain or knowledge acquired during
the course of his employment with the Employer which is generally known to
persons of the Employee's experience in other companies in the same industry.

       D.     ASSIGNMENT OF INTELLECTUAL PROPERTY RIGHTS.

              Employee agrees to assign to the Employer any and all intellectual
       property rights including patents, trademarks, copyright and business
       plans or systems developed, authored or conceived by Employee while so
       employed and relating to the business of the Employer, and Employee
       agrees to cooperate with the Employer's attorneys to perfect ownership
       rights thereof in the Employer or any one or more of the Employer. This
       agreement does not apply to an invention for which no equipment,
       supplies, facility or Trade Secret and Confidential Information of the
       Employer was used and which was developed entirely on Employee's own
       time, unless (a) the invention relates either to the business of the
       Employer or to actual or demonstrably anticipated research or development
       of the Parking Companies, or (b) the invention results from any work
       performed by Employee for the Parking Companies.

       E.     INEVITABLE DISCLOSURE.

              Based upon the Recitals to this Agreement and the representations
       Employee has made in Paragraphs V.A. and V.B. above, Employee
       acknowledges that the Employer's business is highly competitive and that
       it derives significant value from both its Trade Secret and Confidential
       Information not being generally known in the marketplace and from their
       long-standing near-permanent customer relationships. Based upon this
       acknowledgment and the acknowledgments in Paragraphs V.A. and V.B.,
       Employee further acknowledges that he inevitably would disclose the
       Employer's Trade Secret and Confidential Information, including trade
       secrets, should Employee serve as director, officer, manager, supervisor,
       consultant, independent contractor, owner of greater than 1% of the
       stock, representative, agent, or executive (where Employee's duties as an
       employee would involve any level of strategic, advisory, technical,
       creative sales, or other similar input) for any person, partnership,
       joint venture, firm, corporation, or other enterprise which is a
       competitor of the Employer engaged in providing parking facility
       management services because it would be impossible for Employee to serve
       in any of the above capacities for such a competitor of the Employer
       without using or disclosing the Employer's Trade Secret and Confidential
       Information, including trade secrets.

       F.     NON-SOLICITATION.

                                       5
<Page>

              Employee agrees that while employed by the Employer and for a
       period of eighteen (18) months after the Date of Termination, Employee
       shall not, directly or indirectly:

       (1)    without first obtaining the express written permission of the
              Employer's General Counsel which permission may be withheld solely
              in the Employer's discretion, directly or indirectly contact or
              solicit business from any client or customer of the Employer with
              whom Employee had any contact or about whom Employee acquired any
              Trade Secret or Confidential Information during employment with
              the Employer or about whom Employee has acquired any information
              as a result of Employee's employment with the Employer. Likewise,
              Employee shall not, without first obtaining the express written
              permission of the Employer's General Counsel which permission may
              be withheld solely in the Employer's discretion, directly or
              indirectly contact or solicit business from any person responsible
              for referring business to the Employer or who regularly refers
              business to the Employer with whom Employee had any contact or
              about whom Employee acquired any Trade Secret or Confidential
              Information during employment with the Employer or about whom
              Employee has acquired any information as a result of Employee's
              employment with the Employer. Employee's obligations set forth in
              this subparagraph are in addition to those obligations and
              representations, including those regarding Trade Secret and
              Confidential Information and Inevitable Disclosure set forth
              elsewhere in this Agreement; or

       (2)    take any action to recruit or to assist in the recruiting or
              solicitation for employment of any officer, employee or
              representative of the Parking Companies.

              It is not the intention of the Employer to interfere with the
              employment opportunities of former employees except in those
              situations, described above, in which such employment would
              conflict with the legitimate interests of the Employer. If the
              Employee, after the termination of his employment hereunder, has
              any question regarding the applicability of the above provisions
              to a potential employment opportunity, Employee acknowledges that
              it is Employee's responsibility to contact the Employer so that
              the Employer may inform Employee of its position with respect to
              such opportunity.

       G.     REMEDIES.

              Employee acknowledges that Employer would be irreparably injured

       Employer, in addition to any other remedies available to it by reason of
       such breach or threatened breach, shall be entitled to a preliminary

VIII.    ARBITRATION OF DISPUTES

       A.     SCOPE OF AGREEMENT.

              Employer and Employee agree to take all reasonable steps to
       resolve any employment-related legal and/or judicial disputes between
       them quickly and fairly. Should such matters remain unresolved, Employer
       and Employee agree that final and binding arbitration shall be the
       exclusive remedy for any dispute between them relating to all common law,
       statutory, legal or judicial claims, including, but not limited to, any
       claims for breach of contract and for violation of laws forbidding
       discrimination on the basis of race, color, religion, gender, age,
       national origin, disability, or any other legally protected status.
       Explicitly excluded from this provision are claims regarding or relating
       to amount and/or adequacy of compensation, promotion, transfer,
       reassignment of job duties and responsibilities, and discipline, except
       to the extent that such disputes involve common law, statutory, legal or
       judicial claims.

              This Agreement does not preclude administrative claims for
       workers' compensation or unemployment compensation benefits or the filing
       of charges with government agencies.

              Any controversy over whether a dispute is an arbitrable dispute or
       as to the interpretation or enforceability of the paragraph with respect
       to such arbitration shall be determined by the arbitrator. This Agreement
       does not affect substantive rights; it simply

                                       7
<Page>

       governs forum. For example, the arbitrator is to apply the same statutes
       of limitations and to award the same relief that a court would in a
       judicial proceeding.

       B.     PROCEDURE.

              Arbitration shall be before a single arbitrator in the city in
       which the Employee's immediate supervisor maintains his/her main office
       when the matter is submitted to arbitration, unless the parties mutually
       agree to hold the arbitration in a different location. The arbitration
       will be administered in accordance with the employment dispute rules of
       the American Arbitration Association (AAA), and its procedures then in
       effect. If the parties cannot agree on an arbitrator, then the AAA rules
       will govern selection. The Employer will pay the fees of the AAA and the
       arbitrator. However, in the event that the Employee submits a matter to
       arbitration, he/she shall be responsible for contributing to such fees an
       amount equivalent to the amount required to file a complaint of the same
       type in the state court which is geographically closest to the site of
       the arbitration.

              The arbitrator's award is to be in writing, with reasons given and
       evidence cited for the award. The arbitrator shall have the discretion to
       award fees (including administrative charges, costs and/or reasonable
       attorney's fees actually expended) to the prevailing party, in accordance
       with controlling law. Any court of competent jurisdiction may enter
       judgment upon the award, either by: (1) confirming the award, or; (2)
       vacating, modifying or correcting the award: (a) on any ground referred
       to in the U.S. Arbitration Act, (b) where the findings of fact are not
       supported by substantial evidence, or; (c) where the conclusions of law
       are erroneous.

IX.    CHOICE OF LAW

This Agreement shall be construed in accordance with the laws and decisions of
the State of Illinois.

X.     MISCELLANEOUS

       A.     This Agreement supersedes all prior agreements and understandings
              either oral or in writing between the parties hereto, and
              expresses the whole and entire agreement between the parties with
              reference to Employee's employment. In the event of a conflict
              between any of the provisions contained in this Agreement and the
              provisions of the Management Agreement, the provisions contained
              herein shall govern and control.

       B.     No purported change or modification or waiver of any provisions of
              this Agreement shall be valid unless the same is in writing and
              signed by the party against whom it is sought to be enforced.

       C.     If any provision of this Agreement is unenforceable, the parties
              agree that that provision and all other provisions of the
              Agreement shall remain in effect to the fullest extent permitted
              by law.

                                       8

       D.     This Agreement shall be binding upon Employee's heirs, executors,
              administrators or other legal representatives. Employee's duties
              hereunder are personal and may not be assigned.

       E.     Employee has executed and delivered this Agreement as Employee's
              free and voluntary act, after having determined that the
              provisions contained herein are of a material benefit to Employee,
              and that the duties and obligations imposed on Employee hereunder
              are fair and reasonable and will not prevent Employee from earning
              a livelihood following the termination of Employee's employment
              with Employer.

       F.     Employee has read and fully understands the terms and conditions
              set forth herein, has had time to reflect on and consider the
              benefits and consequences of entering into this Agreement and has
              had the opportunity to review the terms hereof with an attorney or
              other representative if Employee so chooses.

IN WITNESS WHEREOF, Employee and Employer have executed this Agreement as of the
day and year first written above.
