     This Amendment No. 1 amends the Statement on Schedule 13D with respect to
the common stock (the "Common Stock") of CapMAC Holdings, Inc., previously filed
on April 2, 1997, by the Reporting Persons named therein (the "Schedule 13D").
Capitalized terms used herein without definition shall have the meanings given
to such terms in the Schedule 13D.

Item 5.  Interests in Securities of the Issuer

     Item 5 is amended by adding the following:

     (a) By reason of their relationship with Dillon Read (see Item 2 to
Schedule 13D), as of April 24, 1997, DR Holding and DRI may be deemed pursuant
to Rule 13d-3 under the Act ("Rule 13d-3") to beneficially own 1,520,554 shares
of Common Stock, representing 9.3% of the outstanding shares of Common Stock
reported by the Company to be outstanding at December 31, 1996 (the "Outstanding
Shares"). DR Holding and DRI disclaim beneficial ownership of all shares of
Common Stock held by Dillon Read and the Funds.

     By reason of Dillon Read's relationship with the Funds (see Item 2 to
Schedule 13D), as of April 24, 1997, Dillon Read may be deemed pursuant to Rule
13d-3 to beneficially own 1,520,554 shares of Common Stock (including 76,651
Agency Shares held by Dillon Read as agent for the persons listed on Exhibit J
hereto and 4,456 shares of Common Stock held in its own name), representing 9.3%
of the Outstanding Shares.










<PAGE>

     As of April 24, 1997, Concord II beneficially owns 14,528 shares of Common
Stock, representing .09% of the Outstanding Shares. Concord Japan beneficially
owns 3,631 shares of Common Stock, representing .02% of the Outstanding Shares.
Lexington IV beneficially owns 672 shares of Common Stock, representing .004% of
the Outstanding Shares. Saratoga II beneficially owns 1,312,326 shares of Common
Stock, representing 7.8% of the Outstanding Shares. Saratoga CV beneficially
owns 108,290 shares of Common Stock, representing .7% of the Outstanding Shares.

     In addition, as of April 24, 1997, DRI and the individuals named in Exhibit
J hereto may be deemed to beneficially own the 76,651 Agency Shares,
representing .5% of the Outstanding Shares; however, pursuant to powers of
attorney executed by each such individual in favor of Dillon Read, Dillon Read
has been granted sole voting power and sole investment power with respect to the
Agency Shares. Accordingly, each such person disclaims beneficial ownership of
the Agency Shares held by Dillon Read for his economic benefit. The name of each
such person and the number of Agency Shares and other shares of Common Stock and
the percentage of the Outstanding Shares as to which each such person disclaims
or affirms beneficial ownership are set forth in Exhibit J hereto, which is
incorporated herein by reference.

     Pursuant to its partnership agreement, on April 17, 1997, Lexington IV
distributed an aggregate of 976 shares of Common Stock to its partners.

     On April 7, 1997, Dillon Read, as Agent, released its powers of attorney
with respect to 47,161 shares of Common Stock.

     Except as set forth herein, to the best knowledge of the Reporting Persons,
none of the other persons identified in this filing currently owns, or has any
right to acquire, any shares of the Common Stock.

     (b) As noted in Items 2 of Schedule 13D and 5(a) herein, Dillon Read has
the voting power and investment power with respect to the shares of Common Stock
reported in this Statement as being beneficially owned by the Funds, and with
respect to the Agency Shares. By reason of their relationship with one another,
Dillon Read, DRI and DR Holding may be deemed to share voting and dispositive
powers as to all of the shares of Common Stock reported in Item 5(a) herein that
Dillon Read may be deemed to beneficially own; however, as noted above, DR
Holding and DRI disclaim beneficial ownership of such shares.

     (c) On the following dates, the Reporting Persons exercised warrants for
shares of Common Stock, reducing the number of shares received in lieu of paying
the aggregate exercise price of the warrants in cash, as follows:

                               Warrants     Exercise    Common Stock
                    Date       Exercised     Price        Received
