                                                                    ------------


                SECOND AMENDED AND RESTATED EMPLOYMENT AGREEMENT

         THIS SECOND AMENDED AND RESTATED EMPLOYMENT AGREEMENT ("Agreement") is
made and effective as of March 1, 2004, by and between Ronald J. Mittelstaedt

Agreement dated as of October 1, 1997, by and among the Employee, the Company,
J. Bradford Bishop, Frank W. Cutler and James N. Cutler, Jr., as amended as of

frequently, at the times prescribed in salary administration practices applied
generally to management employees of the Company.

         (b) Performance Bonus. The Employee shall be entitled to an annual cash
bonus (the "Bonus") based on the Company's attainment of reasonable financial
objectives to be determined annually by the Board. The maximum annual Bonus will

life insurance and tax-qualified retirement benefits. The Employee shall be
entitled to four (4) weeks of paid vacation each year of his employment.

         (e) Reimbursement of Other Expenses. The Company agrees to pay or

Company, divulge to any third party or use for his own benefit or the benefit of
any third party or for any purpose other than the exclusive benefit of the
Company, any confidential or proprietary business or technical information
revealed, obtained or developed in the course of his employment with the Company
and which is otherwise the property of the Company or any of its affiliated
corporations, including, but not limited to, trade secrets, customer lists,

the course of his employment as may be necessary or appropriate to the effective
and efficient discharge of his duties to the Company.

                                        2

6.       Property. Both during the Term of his employment and thereafter, the
Employee shall not remove from the Company's offices or premises any Company
documents, records, notebooks, files, correspondence, reports, memoranda and
similar materials or property of any kind unless necessary in accordance with
the duties and responsibilities of his employment. In the event that any such
material or property is removed, it shall be returned to its proper file or
place of safekeeping as promptly as possible. The Employee shall not make,
retain, remove or distribute any copies, or divulge to any third person the
nature or contents of any of the foregoing or of any other oral or written
information to which he may have access, except as disclosure shall be necessary
in the performance of his assigned duties. On the termination of his employment
with the Company, the Employee shall leave with or return to the Company all
originals and copies of the foregoing then in his possession or subject to his
control, whether prepared by the Employee or by others.

7.       Termination By Company.

         (a) Termination for Cause. The employment of the Employee may be
terminated for Cause at any time by the vote of a majority of the Board;
provided, however, that before the Company may terminate the Employee's
employment for Cause for any reason that is susceptible to cure, the Company
shall first send the Employee written notice of its intention to terminate this
Agreement for Cause, specifying in such notice the reasons for such Cause and
those conditions that, if satisfied by the Employee, would cure the reasons for
such Cause, and the Employee shall have 60 days from receipt of such written
notice to satisfy such conditions. If such conditions are satisfied within such
60-day period, the Company shall so advise the Employee in writing. If such
conditions are not satisfied within such 60-day period, the Company may
thereafter terminate this Agreement for Cause on written Notice of Termination
(as defined in Section 9(a)) delivered to the Employee describing with
specificity the grounds for termination.

         Immediately on termination pursuant to this Section 7(a), the Company
shall pay to the Employee in a lump sum his then current Base Salary under
Section 4(a) on a prorated basis to the Date of Termination (as defined in
Section 9(b)). In addition, upon termination of this Agreement for Cause, the
Company shall elect, on or prior to the Date of Termination, whether the
Restricted Period, during which the Employee shall be subject to the
non-competition and non-solicitation provisions of Section 12, shall be zero
days, or until the end of the eighteenth full month following the Date of
Termination (the "Optional Restricted Period"); if the Company elects to apply
the Optional Restricted Period, then in addition to the payment described in the
preceding sentence, the Company shall pay to the Employee in a lump sum on
termination (i) a pro-rated portion of the maximum bonus available to the
Employee under Section 4(b) for the year in which the termination occurs, plus
(ii) an amount equal to three times the Employee's Total Compensation, as
defined below, plus (iii) the Health Insurance Benefit, as defined below. On
termination pursuant to this Section 7(a), the Employee shall forfeit his Bonus
under Section 4(b) for the year in which such termination occurs, unless the
Company elects the Optional Restricted Period as described in the preceding
sentence, in which case the Employee shall receive the pro-rated bonus amount
described in that sentence. In addition, on termination pursuant to this Section
7(a), the Employee shall forfeit all unvested Options and other options,
warrants and rights relating to capital stock of the Company, unless the Company
elects the Optional Restricted Period, in which case all of the Employee's
unvested Options and other options, warrants and rights relating to capital
stock of the Company shall immediately vest and

                                        3

become exercisable, and the term of any such options (including the Options),
warrants and rights shall be extended to the fifth anniversary of the Employee's
termination. The Employee acknowledges that extending the term of any incentive
stock option pursuant to this Section 7(a), or Section 7(b), 7(c), 7(d), 8(a) or
8(b), could cause such option to lose its tax-qualified status under the
Internal Revenue Code of 1986, as amended (the "Code"), and agrees that the
Company shall have no obligation to compensate the Employee for any additional
taxes he incurs as a result.

         For purposes of this Agreement, "Cause" shall mean:

         (1) a material breach of any of the terms of this Agreement that is not
immediately corrected following written notice of default specifying such
breach;

         (2) repeated intoxication with alcohol or drugs while on Company
premises during its regular business hours to such a degree that, in the
reasonable judgment of the other managers of the Company, the Employee is
abusive or incapable of performing his duties and responsibilities under this
Agreement;

         (3) conviction of a felony; or

         (4) misappropriation of property belonging to the Company and/or any of
its affiliates.

         For purposes of this Agreement, the Employee's "Total Compensation"
shall equal the sum of (i) twelve months of the Employee's Base Salary at the
rate in effect on the termination date, (ii) the maximum Bonus of 100% of such
Base Salary (whether or not the entire amount was actually earned or paid to the
Employee), and (iii) the amount of all vehicle allowance and vehicle-related,
telephone and facsimile reimbursements described in Section 4(d) that were
payable to the Employee with respect to the twelve months preceding the
termination date; provided that solely for the purpose of computing Total
Compensation, if at the date of termination the Employee's Base Salary is less
than $295,000 per year, then the Employee's Base Salary shall be deemed to be
$295,000 for the purpose of such computation.

         For purposes of this Agreement, the "Health Insurance Benefit" shall be
an amount equal to the excess of (i) the premiums payable by the Employee to
cover himself, his wife and his children for a three-period period beginning on
the termination date under a health insurance plan that provides benefits
comparable to those available under the Company's health insurance plan then in
effect, over (ii) the premiums that would be payable by the Employee, if he were
still employed by the Company, to cover himself, his wife and his children for
that three-year period under the Company's health insurance plan in effect on
the termination date.

         (b) Termination Without Cause. The employment of the Employee may be
terminated without Cause at any time by the vote of a majority of the Board on
delivery to the Employee of a written Notice of Termination (as defined in
Section 9(a)). On the Date of Termination (as defined in Section 9(b)) pursuant
to this Section 7(b), the Company shall pay to the Employee in a lump sum in
lieu of payments under Section 4(a), 4(b) and 4(d) for the remainder of the Term
an amount equal to the sum of (i) all Base Salary payable under Section 4(a)
through the termination date, (ii) a pro-rated portion of the maximum Bonus
available to the Employee under Section 4(b) for the year in which the
termination occurs, (iii) an amount equal

                                        4

to three times the Employee's Total Compensation, as defined in Section 7(a),
plus (iv) the Health Insurance Benefit, as defined in Section 7(a). In addition,
on termination of the Employee under this Section 7(b), all of the Employee's
unvested Options and other options, warrants and rights relating to capital
stock of the Company shall immediately vest and become exercisable. The term of
any such options (including the Options), warrants and rights shall be extended
to the fifth anniversary of the Employee's termination.

         (c) Termination on Disability. If during the Term the Employee should
fail to perform his duties hereunder on account of physical or mental illness or
other incapacity which the Board shall in good faith determine renders the
Employee incapable of performing his duties hereunder, and such illness or other
incapacity shall continue for a period of more than six (6) consecutive months
("Disability"), the Company shall have the right, on written Notice of
Termination (as defined in Section 9(a)) delivered to the Employee to terminate
the Employee's employment under this Agreement. During the period that the
Employee shall have been incapacitated due to Disability, the Employee shall
continue to receive the full Base Salary provided for in Section 4(a) hereof at
the rate then in effect until the Date of Termination (as defined in Section
9(b)) pursuant to this Section 7(c). On the Date of Termination pursuant to this
Section 7(c), the Company shall pay to the Employee in a lump sum an amount
equal to (i) the Base Salary remaining payable to the Employee under Section
4(a) for the full remaining Term, plus (ii) a pro-rated portion of the maximum
Bonus available to the Employee under Section 4(b) for the year in which the
termination occurs. In addition, on such termination, all of the Employee's
unvested Options and other options, warrants and rights relating to capital
stock of the Company shall immediately vest and become exercisable. The term of
any such options (including the Options), warrants and rights shall be extended
to the fifth anniversary of the Employee's termination.

         (d) Termination on Death. If the Employee shall die during the Term,
the employment of the Employee shall thereupon terminate. On the Date of
Termination (as defined in Section 9(b)) pursuant to this Section 7(d), the
Company shall pay to the Employee's estate the payments and other benefits
applicable to termination without Cause set forth in Section 7(b) hereof, except
that the Health Insurance Benefit shall be calculated with respect to coverage
only for the Employee's wife and children. In addition, on termination of the
Employee under this Section 7(d), all of the Employee's unvested Options and
other options, warrants and rights relating to capital stock of the Company
shall immediately vest and become exercisable. The term of any such options
(including the Options), warrants and rights shall be extended to the fifth
anniversary of the Employee's termination. The provisions of this Section 7(d)
shall not affect the entitlements of the Employee's heirs, executors,
administrators, legatees, beneficiaries or assigns under any employee benefit
plan, fund or program of the Company.

8.       Termination By Employee.

         (a) Termination for Good Reason. The Employee may terminate his
employment hereunder for Good Reason (as defined below). On the Date of
Termination pursuant to this Section 8(a), the Employee shall be entitled to
receive, and the Company agrees to pay and deliver, the payments and other
benefits applicable to termination without Cause set forth in Section 7(b)
hereof at the times and subject to the conditions set forth therein. In
addition, on termination of the Employee under this Section 8(a), all of the
Employee's Options and other options, warrants and rights relating to capital
stock of the Company shall immediately vest and

                                        5

become exercisable. The term of any such options (including the Options),
warrants and rights shall be extended to the fifth anniversary of the Employee's
termination.

         For purposes of this Agreement, "Good Reason" shall mean:

               (1) assignment to the Employee of duties inconsistent with his
responsibilities as they existed on the date of this Agreement; a substantial
alteration in the title(s) of the Employee (so long as the existing corporate
structure of the Company is maintained); or a substantial alteration in the
status of the Employee in the Company organization as it existed on the date of
this Agreement;

               (2) the relocation of the Company's principal executive office to
a location more than fifty (50) miles from its present location;

               (3) a reduction by the Company in the Employee's Base Salary
without the Employee's approval;

               (4) a failure by the Company to continue in effect, without
substantial change, any benefit plan or arrangement in which the Employee was
participating or the taking of any action by the Company which would adversely
affect the Employee's participation in or materially reduce his benefits under
any benefit plan (unless such changes apply equally to all other management
employees of Company);

               (5) any material breach by the Company of any provision of this
Agreement without the Employee having committed any material breach of his
obligations hereunder, which breach is not cured within twenty (20) days
following written notice thereof to the Company of such breach; or

               (6) the failure of the Company to obtain the assumption of this
Agreement by any successor entity.

         (b) Termination Without Good Reason. The Employee may terminate his
employment hereunder without Good Reason on written Notice of Termination
delivered to the Company setting forth the effective date of termination. If the
Employee terminates his employment hereunder without Good Reason, he shall be
entitled to receive, and the Company agrees to pay on the effective date of
termination specified in the Notice of Termination, his current Base Salary
under Section 4(a) hereof on a prorated basis to such date of termination. In
addition, upon the Employee's termination of his employment without Good Reason,
the Company shall elect, within fifteen (15) days after receiving the Notice of
Termination, whether the Restricted Period, during which the Employee shall be
subject to the non-competition and non-solicitation provisions of Section 12,
shall be zero days, or the Optional Restricted Period; if the Company elects to
apply the Optional Restricted Period, then in addition to the payment described
in the preceding sentence, the Company shall pay to the Employee in a lump sum
on termination (i) a pro-rated portion of the maximum bonus available to the
Employee under Section 4(b) for the year in which the termination occurs, plus
(ii) an amount equal to three times the Employee's Total Compensation, as
defined in Section 7(a), plus (iii) the Health Insurance Benefit, as defined in
Section 7(a). On termination pursuant to this Section 8(b), the Employee shall
forfeit his Bonus under Section 4(b) for the year in which such termination
occurs, unless the Company elects the Optional Restricted Period as described in
the preceding sentence, in

                                        6

which case the Employee shall receive the pro-rated bonus amount described in
that sentence. In addition, on termination pursuant to this Section 8(b), the
Employee shall forfeit all unvested Options and other options, warrants and
rights relating to capital stock of the Company, unless the Company elects the
Optional Restricted Period, in which case all of the Employee's unvested Options
and other options, warrants and rights relating to capital stock of the Company
shall immediately vest and become exercisable, and the term of any such options
(including the Options), warrants and rights shall be extended to the fifth
anniversary of the Employee's termination.

9.       Provisions Applicable to Termination of Employment.

         (a) Notice of Termination. Any purported termination of Employee's
employment by the Company pursuant to Section 7 shall be communicated by Notice
of Termination to the Employee as provided herein, and shall state the specific
termination provisions in this Agreement relied on and set forth in reasonable
detail the facts and circumstances claimed to provide a basis for termination of
the Employee's employment ("Notice of Termination"). If the Employee terminates
under Section 8, he shall give the Company a Notice of Termination.

         (b) Date of Termination. For all purposes, "Date of Termination" shall
mean, for Disability, thirty (30) days after Notice of Termination is given to
the Employee (provided the Employee has not returned to duty on a full-time
basis during such 30-day period), or, if the Employee's employment is terminated
by the Company for any other reason or by the Employee, the date on which a
Notice of Termination is given.

         (c) Benefits on Termination. On termination of this Agreement by the
Company pursuant to Section 7 or by the Employee pursuant to Section 8, all
profit-sharing, deferred compensation and other retirement benefits payable to
the Employee under benefit plans in which the Employee then participated shall
be paid to the Employee in accordance with the provisions of the respective
plans.

10.      Change In Control.

         (a) Payments on Change in Control. Notwithstanding any provision in
this Agreement to the contrary, unless the Employee elects in writing to waive
this provision, a Change in Control (as defined in Section 11(d) below) of the
Company shall be deemed a termination of the Employee without Cause, and the
Employee shall be entitled to receive and the Company agrees to pay to the
Employee, in a lump sum upon such Change in Control, the amount determined under
Section 7(b) that is payable to the Employee on termination without Cause. In
addition, on a Change of Control, all of the Employee's unvested Options and
other options, warrants and rights relating to capital stock of the Company
shall immediately vest and become exercisable, and the term of any such options
(including the Options), warrants and rights shall be extended to the fifth
anniversary of the Employee's termination.

         After a Change in Control, if any option (including the Options),
warrant or right (the "Terminated Option") relating to the Company's capital
stock does not remain outstanding, the successor to the Company or its then
Parent (as defined in Section 10 below) shall either:

               (i) Issue an option, warrant or right, as appropriate (the
"Successor Option"), to purchase common stock of such successor or Parent in an
amount such that on

                                        7

exercise of the Successor Option the Employee would receive the same number of
shares of the successor's/Parent's common stock as the Employee would have
received had the Employee exercised the Terminated Option immediately prior to
the transaction resulting in the Change in Control and received shares of such
successor/Parent in such transaction. The aggregate exercise price for all of
the shares covered by such Successor Option shall equal the aggregate exercise
price of the Terminated Option; or

               (ii) Pay the Employee a bonus within ten (10) days after the
consummation of the Change in Control, in an amount agreed to by the Employee
and the Company. Such amount shall be at least equivalent on an after-tax basis
to the net after-tax gain that the Employee would have realized if he had been
issued a Successor Option under clause (i) above and had immediately exercised
such Successor Option and sold the underlying stock, taking into account the
different tax rates that apply to such bonus and to such gain, and such amount
shall also reflect other differences to the Employee between receiving a bonus
under this clause (ii) and receiving a Successor Option under clause (i) above.

         (b) Definitions. For the purposes of this Agreement, a Change in
Control shall be deemed to have occurred if (i) there shall be consummated (aa)
any reorganization, liquidation or consolidation of the Company, or any merger
or other business combination of the Company with any other corporation, other
than any such merger or other combination that would result 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) at least fifty percent (50%) of the total
voting power represented by the voting securities of the Company or such
surviving entity outstanding immediately after such transaction, (bb) any sale,
lease, exchange or other transfer (in one transaction or a series of related
transactions) of all, or substantially all, of the assets of the Company, or if
(ii) any "person" (as defined in Section 13(d) and 14(d) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act")), shall become the
"beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly
or indirectly, of fifty percent (50%) or more of the Company's outstanding
voting securities (except that for purposes of this Section 10(b), "person"
shall not include any person (or any person that controls, is controlled by or
is under common control with such person) who as of the date of this Agreement
owns ten percent (10%) or more of the total voting power represented by the
outstanding voting securities of the Company, or a trustee or other fiduciary
holding securities under any employee benefit plan of the Company, or a
corporation that is owned directly or indirectly by the stockholders of the
Company in substantially the same percentage as their ownership of the Company)
or if (iii) during any period of two consecutive years, individuals who at the
beginning of such period constituted the entire Board shall cease for any reason
to constitute at least one-half of the membership thereof unless the election,
or the nomination for election by the Company's shareholders, of each new
director was approved by a vote of at least one-half of the directors then still
in office who were directors at the beginning of the period.

         The term "Parent" means a corporation, partnership, trust, limited
liability company or other entity that is the ultimate "beneficial owner" (as
defined above) of fifty percent (50%) or more of the Company's outstanding
voting securities.

11.      Gross Up Payments. If all or any portion of any payment or benefit that
the Employee is entitled to receive from the Company pursuant to this Agreement
(a "Payment") constitutes an "excess parachute payment" within the meaning of
Section 280G of the Code, and as such is

                                        8

subject to the excise tax imposed by Section 4999 of the Code or to any similar
Federal, state or local tax or assessment (the "Excise Tax"), the Company or its
successors or assigns shall pay to the Employee an additional amount (the
"Gross-Up Payment") with respect to such Payment. The amount of the Gross-Up
Payment shall be sufficient that, after paying (a) any Excise Tax on the
Payment, (b) any Federal, state or local income or employment taxes and Excise
Tax on the Gross-Up Payment, and (c) any interest and penalties imposed in
respect of the Excise Tax, the Employee shall retain an amount equal to the full
amount of the Payment. For the purpose of determining the amount of any Gross-Up
Payment, the Employee shall be deemed to pay Federal income taxes at the highest
marginal rate applicable in the calendar year in which the Gross-Up Payment is
made, and state and local income taxes at the highest marginal rate applicable
in the state and locality where the Employee resides on the date the Gross-Up
Payment is made, net of the maximum reduction in Federal income taxes that could
be obtained from deducting such state and local taxes.

         The Gross-Up Payment with respect to any Payment shall be paid to the
Employee within ten (10) days after the Internal Revenue Service or any other
taxing authority issues a notice stating that an Excise Tax is due with respect
to the Payment, unless the Company undertakes to challenge the taxing authority
on the applicability of such Excise Tax and indemnifies the Employee for (a) any
amounts ultimately determined to be payable, including the Excise Tax and any
related interest and penalties, (b) all expenses (including attorneys' and
experts' fees) reasonably incurred by the Employee in connection with such
challenge, as such expenses are incurred, and (c) all amounts that the Employee
is required to pay to the taxing authorities during the pendency of such
challenge (such amounts to be repaid by the Employee to the Company if they are
ultimately refunded to the Employee by the taxing authority).

12.      Non-Competition and Non-Solicitation.

         (a) In consideration of the provisions hereof and the payments provided
under Sections 7, 8 and 10(a), for the Restricted Period (as hereinafter
defined), the Employee will not, except as specifically provided below, anywhere
in any county in any state in which the Company is engaged in business as of
such termination date (the "Restricted Territory"), directly or indirectly,
acting individually or as the owner, shareholder, partner or management employee
of any entity, (i) engage in the operation of a solid waste collection,
transporting or disposal business, transfer facility, recycling facility,
materials recovery facility or solid waste landfill; (ii) enter the employ as a
manager of, or render any personal services to or for the benefit of, or assist
in or facilitate the solicitation of customers for, or receive remuneration in
the form of management salary, commissions or otherwise from, any business

         (c) If the final judgment of a court of competent jurisdiction declares
that any term or provision of this Section 12 is invalid or unenforceable, the
parties agree that the court making the determination of invalidity or
unenforceability shall have the power to reduce the scope, duration or area of
the term or provision, to delete specified words or phrases or to replace any
invalid or unenforceable term or provision with a term or provision that is
valid and enforceable and that comes closest to expressing the intention of the
invalid or unenforceable term or provision, and this Agreement shall be
enforceable as so modified after the expiration of the time within which the
judgment may be appealed.

5, 6 and 12 of this Agreement and of the Company under Section 13 of this
Agreement shall survive both the termination of the Employee's employment and
this Agreement.

16.      No Duty to Mitigate; No Offset. The Employee shall not be required to
mitigate damages or the amount of any payment contemplated by this Agreement,
nor shall any such payment be reduced by any earnings that the Employee may
receive from any other sources or offset against any other payments made to him
or required to be made to him pursuant to this Agreement.

nature between them. This Agreement may not be changed except by an agreement in
writing signed by the Company and the Employee.

20.      Waiver. The waiver of a breach of any provision of this Agreement shall

governed by and construed and enforced in accordance with the laws of the State
of California. The parties irrevocably and unconditionally submit to the

proceeding arising out of, or relating to or in connection with, this Agreement.

22.      Severability. In case any one or more of the provisions contained in
this Agreement is, for any reason, held invalid in any respect, such invalidity
shall not affect the validity of any other provision of this Agreement, and such
provision shall be deemed modified to the extent necessary to make it
enforceable.

23.      Enforcement. It is agreed that it is impossible to measure fully, in
money, the damage which will accrue to the Company in the event of a breach or
threatened breach of Section 5 or 6 of this Agreement, and, in any action or
proceeding to enforce the provisions of Section 5 or 6 hereof, the Employee
waives the claim or defense that the Company has an adequate remedy at law and
will not assert the claim or defense that such a remedy at law exists. The
Company is entitled to injunctive relief to enforce the provisions of such
sections as well as any and all other remedies available to it at law or in
equity without the posting of any bond.
