FOR IMMEDIATE RELEASE
- ---------------------

                RURAL/METRO REPORTS STRONG THIRD QUARTER REVENUE
                            AND OPERATING PERFORMANCE
              COMPANY ANNOUNCES $7 MILLION UNSCHEDULED DEBT PAYMENT

SCOTTSDALE, ARIZ. (May 16, 2005) - Rural/Metro Corporation (Nasdaq/SC: RURL), a
leading provider of medical transportation and private fire protection services,
today announced financial results for its fiscal 2005 third quarter ended March
31, 2005.

Net revenue for the fiscal 2005 third quarter increased 8.2% to $145.2 million,
compared to $134.3 million in the prior year's third quarter. Net revenue for
the nine months ended March 31, 2005 increased 6.4% to $418.9 million, compared
to $393.8 million for the same period a year ago. Fiscal 2005 third-quarter and
year-to-date revenue growth primarily reflects a combination of an increase in
the number of medical transports and higher billing rates in both the company's
medical transportation and fire protection businesses.

For the fiscal 2005 third quarter, the company reported a loss of $3.0 million,
or a loss of $0.13 per diluted share, compared to net income of $2.2 million, or
$0.00 per diluted share for the prior year's third quarter. Third-quarter fiscal
2005 results include a loss on the early extinguishment of debt of $8.2 million,
which represents an after-tax loss of $0.32 per diluted share. This loss is
comprised of non-cash write-offs of $5.6 million in debt issuance costs and
$0.1 million in unamortized discounts, as well as $2.5 million related to cash
redemption premiums.

Net income for the fiscal 2005 nine-month period was $4.5 million, or $0.19 per
diluted share, compared to net income of $4.9 million, or $0.04 per diluted
share for the same period a year ago. Fiscal 2005 nine-month results include a
loss on the early extinguishment of debt of $8.2 million, which represents an
after-tax loss of $0.32 per diluted share. The loss per share for the fiscal
2004 period included the impact of allocating net income to the company's former
Series B and Series C preferred stock, as well as a related accretion charge.


Rural/Metro today also announced that it made a $7.0 million unscheduled payment
to reduce the principal balance of its Term Loan B from $135.0 million to $128.0
million. The company anticipates a resulting interest savings of approximately
$350,000 per year.

Jack Brucker, President and Chief Executive Officer, said, "We are pleased with
our ongoing efforts to extend our presence in high-growth service areas and
generate solid and consistent revenue growth. At the same time, we are deriving
benefits from ongoing improved operating efficiencies that provide greater
flexibility to selectively enter new markets. Each of these factors enable us to
make progress toward our goal to improve the company's long-term liquidity
through debt reduction."

REVENUE BY SEGMENT
- ------------------

Medical Transportation and Related Services: Same-service-area medical
transportation revenue increased 7.3% for the third quarter ended March 31, 2005
and 5.5% year-to-date compared to the same prior year periods. Net revenue in
this segment for the fiscal 2005 third quarter increased 7.9% to $125.1 million,
compared to $115.9 million in the prior year's third quarter. For the nine
months ended March 31, 2005, net revenue increased 5.9% to $358.5 million,
compared to $338.4 million for the prior year period. The company attributed the
growth in the segment to higher transport volume and increases in rates.

Fire and Other: Fire and other revenue for the fiscal 2005 third quarter
increased 9.7% to $20.1 million, compared to $18.4 million in 2004. For the nine
months ended March 31, 2005, fire and other revenue increased 9.0% to $60.5
million, compared to $55.4 million for the prior year nine-month period. Revenue
growth in the fire and other segment primarily reflects general rate increases
and an increase in the number of new fire subscription customers.

DEBT REFINANCING
- ----------------

During the third quarter, the company refinanced its former amended credit
facility and senior notes. The company entered into a new senior secured credit
facility, consisting of a $135.0 million Term Loan B due 2011; a $20.0 million,
undrawn revolving credit facility due 2010; and a $35.0 million letter of credit
facility due 2011. Concurrently, the company issued $125.0 million of 9.875%
senior subordinated notes due 2015 and the company issued $93.5 million
aggregate principal amount at maturity (gross proceeds of $50.2 million) of
12.75% senior discount notes due 2016.

Mr. Brucker continued, "With improved cash flows and an improving balance sheet,
we have established a solid foundation to capitalize on the growing demand for
our services and we believe our long-term business prospects are positive. Our
new debt structure provides greater strength and flexibility to expand our
operations in existing service areas and select new markets that are consistent
with our strategic growth objectives."

EBITDA RESULTS
- --------------

For the third quarter ended March 31, 2005, earnings before interest, taxes,
depreciation and amortization ("EBITDA") was $6.9 million, compared to $12.3
million for the prior-year comparable period. Third-quarter fiscal 2005 EBITDA
includes the $8.2 million loss on early extinguishment of debt.

For the nine months ended March 31, 2005, EBITDA was $35.5 million, compared to
$36.7 million for the same period a year ago. Fiscal 2005 nine-month EBITDA
includes the $8.2 million loss on early extinguishment of debt.

The company regards EBITDA, which is widely used by analysts, investors,
creditors, and other interested parties, as relevant and useful information. The
company provides this information to permit additional analysis of its ability
to meet future debt service, capital expenditures, and working capital
requirements. Additionally, the company's management uses this information to
evaluate the performance of its operating units. EBITDA is not intended to
represent cash provided by operating activities as defined by generally accepted
accounting principles, and it should not be considered as an indicator of
operating performance or an alternative to cash provided by operating activities
as a measure of liquidity. The company has provided a reconciliation of net
income to EBITDA in the attached tables.

OPERATING METRICS
- -----------------

The company's key operating metrics continued to trend positively in the fiscal
2005 third quarter. Medical transport volume grew 5.0% to 279,312 transports,
compared to 266,064 in last year's third quarter. Additionally, net/net EMS
average patient charge ("net/net EMS APC") grew 5.8%, or $18 per transport, to
$330 compared to $312 for the third quarter of 2004. The company considers
net/net EMS APC its best approximation of cash collected per transport. For the
fiscal 2005 third quarter, average quarterly days sales outstanding ("DSO")
dropped to 43 days compared to 45 days in the prior year's third quarter.

Mr. Brucker continued, "We are committed to building on the positive momentum we
have created in these and other key performance areas and we continue to focus
on high-quality, low-risk growth in existing and select new markets while
further enhancing our operational efficiencies and billing effectiveness."

Following is a summary of certain of the company's key operating statistics.
Medical transports and net/net EMS APC statistics have been adjusted to
eliminate discontinued operations for all periods presented:
