Supply Segment Revenues Increase 109.4% from same period of 2009

First quarter 2010 revenue increased 24.7% to $11.6 million from $9.3

income increased 33.7% for the three months ended March 31, 2010 to $0.7

million, compared to net income of $0.5 million for the three months ended March 31,

increased by $2.9 million, or 22.4%, to $16.0 million as of March 31, 2010

from December 31, 2009. The increase was primarily due to an increase in

inventory for the Infection Control segment as the result of a stockpiling of

N-95 particulate respirator masks, as well as an increase for the Disposable

Protective Apparel segment.

Company revised its Disposable Protective Apparel segment

distribution strategy as it shifts its Critical Cover product line from its previous exclusive

distributor to a broader, more diverse distribution network.

Nogales, Arizona May 5, 2010, Alpha Pro Tech, Ltd.

(NYSE Amex: APT), a leading manufacturer of products designed to protect

people, products and environments, including disposable protective apparel and

building products, today announced its

financial results for the

first quarter ended March 31, 2010.

sales for the first quarter of 2010 increased 24.7% to $11.6 million from $9.3

million in the comparable quarter in 2009.

Sales for the Disposable Protective Apparel segment for the three months

ended March 31, 2010 increased by 5.2% to $5.1 million, compared to $4.8

million for the same period of 2009. Building Supply segment sales for the

three months ended March 31, 2010 increased by 109.4% to $4.7 million,

compared to $2.3 million for the same period of 2009. Building Supply segment sales were also up

18.0% sequentially from $4.0 million in the fourth quarter of 2009. The segment increase was primarily due to a

135.8% increase in sales of REX SynFelt synthetic roof underlayment and a

73.6% increase in sales of REX Wrap housewrap from the first quarter of 2009. The sales mix of the Building Supply segment

for the three months ended March 31, 2010 was 70% for synthetic roof

underlayment and 30% for housewrap. This compared to 64% for synthetic roof

underlayment and 36% for housewrap for the first quarter of 2009. Infection Control segment sales for the three

months ended March 31, 2010 decreased by 18.5% to $1.8 million, compared

to $2.2 million for the same period of 2009.

Mask sales were up by 22.3%, or $0.2 million, and shield sales were down

by 61.6%, or $0.7 million.

Millar, President of Alpha Pro Tech commented, Sales for the Disposable

Protective Apparel segment increased primarily due to improved sales of

disposable shoecovers. The segment increase was related primarily to increased

to a broad base of our distribution network and, in particular, to a major

national distributor with which we have preferred vendor status and from which

we received the Outstanding Performance Controlled Environments vendor award

for 2009. The increase was partially offset by decreased sales to our largest

distributor. Sales in the first quarter

of 2010 continued to be adversely affected by a supply chain delay of goods

from Asia. This delay is expected to be

resolved in the second quarter of 2010.

continued, As we announced in late March 2010, we are shifting to a more

diversified, broader and global distribution strategy for our Disposable

Protective Apparel product line as we shift away from VWR International, LLC as

the sole distributor of our Critical

Cover product line. We are working

closely with our distribution partners to ensure continuity in our distribution

channel to minimize potential supply-chain interruptions. We are committed to

producing the highest quality products, and we have an obligation to our

customers and our shareholders to protect our brand. The change in our relationship with our

largest disposable protective apparel distributor could adversely affect sales

in the short term, but we expect it to be beneficial in the long term as we

develop a broader base of distribution.

This is similar to the distribution change that we implemented in the

Building Supply segment in 2007, and, ultimately, it was the catalyst of our

growth in that segment over the past few years.

concluded, Shield sales were down in the first quarter of 2010 due to a $1.7

million non-recurring shield order received in the fourth quarter of 2008. That

order was shipped out over a period of three quarters beginning in the fourth

quarter of 2008. The increase in mask sales for the three months ended March 31,

2010 was primarily attributable to an increase in our general purpose line of

facemasks. Our N-95 respirator mask sales were up slightly in the first quarter

of 2010 and are expected to return to pre-H1N1 levels in 2010 unless concerns

relating to the global H1N1 Influenza A pandemic resume, although we continue

to work on securing large international orders for our N-95 respirator mask

that are unrelated to H1N1.

profit for the three months ended March 31, 2010 increased 21.1% to $5.0

million for the first quarter 2010, or 42.9% gross profit margin, from $4.1

million, or 44.2% gross profit margin, for the same period in 2009. Gross profit margin for the three months

ended March 31, 2010 was negatively affected by the change in product mix

in which Building Supply segment sales, which have lower margins, increased as

a percentage of total sales.

general and administrative expenses increased by 16.8% to $3.8 million for the

first quarter 2010 from $3.2 million for the same quarter last year. The increase was primarily due to increased

employee compensation, increased sales and marketing expenses and increased

travel expenses. As a percentage of net

sales, selling, general and administrative expenses decreased to 32.5% for the

three months ended March 31, 2010 from 34.7% for the same period in 2009.

income increased 33.7% for the three months ended March 31, 2010 to $0.7

million, compared to net income of $0.5 million for the three months ended March 31,

2009. Net income as a percentage of

sales for the three months ended March 31, 2010 and 2009 was 5.9% and

5.5%, respectively. Basic income per

share for the three months ended March 31, 2010 and 2009 was $0.03 and

$0.02, respectively. Diluted income per

share for the three months ended March 31, 2010 and 2009 was $0.03 and

$0.02, respectively.

Balance Sheet remained strong with a current ratio of 17 to 1 as of March 31,

2010. The Company completed the quarter

with cash and cash equivalents of $5.4 million, down from $9.8 million as of December 31,
