                          ---------------------
                   BYL BANCORP TO ACQUIRE DNB FINANCIAL
                   ------------------------------------

Yorba Linda, CA. -- BYL Bancorp ("BYL") (NASDAQ NMS:BOYL), parent company of 
the Bank of Yorba Linda, and DNB Financial ("DNB"), the parent company of De 
Anza National Bank, announced today the execution of a Definitive Agreement 
("Agreement") for BYL to acquire DNB. Under the terms of the acquisition, DNB 
will be merged with and into BYL, and De Anza National Bank will become an 
operating division of the Bank of Yorba Linda. The transaction will be 
structured as a pooling of interests through a tax-free exchange of BYL 
shares of common stock for all outstanding shares of DNB common stock.

DNB is a closely held, $73.4 million total asset bank holding company whose 
subsidiary, De Anza National Bank, operates three full-service commercial 
banking branches in Mira Loma, Indian Hills, Riverside in Riverside County, 
California.

The Agreement has been approved by the boards of directors of both companies
and is subject to the approval of the shareholders of both BYL and DNB and 
appropriate regulatory agencies. The merger is expected to close by May 31, 
1998.

Under the terms of the Agreement, if the transaction closes on May 31, 1998, 
the estimated total transaction value will be approximately $20.0 million. 
Assuming a closing on May 31, 1998, approximately 4.59 BYL shares will be 
exchanged at a stipulated value of $18.75 per BYL share for each of the 
232,423 DNB shares, or a total of approximately 1,067,700 BYL shares. The 
estimated total transaction value at May 31, 1998 represents approximately 
2.5 times the estimated DNB tangible book value at May 31, 1998 and 
approximately 25.7 times the DNB estimated net income for the twelve months 
ended May 31, 1998.

The aggregate transaction value for DNB will be subject to adjustment based 
upon the tangible book value of DNB at the date of closing. The aggregate 
transaction value will be the sum of (a) $19,569,722, or approximately 2.53 
times the DNB tangible book value at December 31, 1997 and (b) 1.5 times the 
change in the DNB tangible book value between December 31, 1997 and the 
closing.

The total number of BYL shares to be exchanged will be determined by dividing 
the aggregate transaction value for DNB by the stipulated value of $18.75 per 
BYL share. The stipulated value per BYL share will be adjusted if the average 
closing BYL stock price during the pricing determination period is greater 
than $22.50 or less than $15.00 per share. The pricing determination period 
will be the twenty consecutive trading days ending three days prior to the 
closing of the transaction. BYL may terminate the transaction if the average 
closing price during the pricing determination period is less than $12.19 per 
share, and DNB may terminate if the average closing price during the pricing 
determination period is greater than $25.31 per share. If the stipulated 
value per BYL share of $18.75 is adjusted, the amount of the adjustment will 
equal one half of the difference between the average closing price per BYL 
share during the pricing determination period and $18.75.
