                             CONVERSION FROM LIMITED
                        LIABILITY COMPANY TO CORPORATION

          1.1 Consent to Conversion; Further Action. Each Member hereby consents
to, and waives any provision of any agreement to which he, she or it is a party
that would prohibit or restrict, the conversion of the Company from a limited
liability company organized under the laws of the State of Delaware to a
corporation incorporated in the State of Delaware pursuant to Section 265 of the
General Corporation Law of the State of Delaware (the "DGCL") and Section 18-216
of the Limited Liability Company Act of the State of Delaware. Each Member
further agrees that at any time prior to the Effective Time (as defined herein),
notwithstanding authorization of the Conversion hereunder, the Company may
abandon the Conversion without further action by the Members, if in its judgment
and discretion the Managing Member of the Company determines the Conversion is
no longer advisable to, and in the best interest of, the Company and the
Members. Each Member agrees to execute, acknowledge and deliver such further
instruments, and to do all such other acts, as may be necessary or appropriate
in order to carry out the Conversion in accordance with (i) such statutes and
(ii) the purposes and intent of this Agreement.

          1.2 Effective Time of the Conversion. The effectiveness of the
Conversion (the "Effective Time") shall be upon the delivery to, and acceptance
for filing by, the Secretary of State of the State of Delaware, as provided in
the DGCL, of the Certificate of Conversion in the form attached hereto as
Exhibit B and the Certificate of Incorporation in the form attached hereto as
Exhibit C (the "Certificate of Incorporation").

          1.3 "C" Corporation. The corporation resulting from the Conversion
(the "Corporation") shall be treated for all purposes as a corporation subject
to subchapter C of the Internal Revenue Code, and shall make no elections to the
contrary.

          1.4 Governing Documents of the Corporation. The Corporation shall be
initially governed by (i) the Certificate of Incorporation and (ii) By-laws in
the form attached hereto as Exhibit D (the "By-laws"), in each case as may be
amended from time to time in accordance with their respective terms.

          1.5 Capitalization of the Corporation. At the Effective Time, the

par value $0.001 per share (the "Common Stock"), in the amounts set forth on
Schedule 1.5 next to the name of each Member in consideration of the interests
of each such Member in the Company. Each Member agrees that the issuance as set
forth in this Section is in accordance with the Operating Agreement. Upon
issuance pursuant to the Conversion, all of the shares of Common Stock will be
duly authorized and validly issued, fully paid and non-assessable. Nothing in
this Section shall limit or restrict the right of the Corporation from time to
time to issue such additional equity securities, including options or other
securities exercisable for or convertible or exchangeable into its capital
stock, as may be approved by its Board of Directors in accordance with the terms
of the Certificate of Incorporation and the By-laws.

          1.6 Board of Directors and Officers. The initial members of the Board
of Directors and the officers of the Corporation shall be as set forth on

Incorporation and the By-laws.

          1.7 Member Representations and Indemnity. Each Member, severally and
not jointly, hereby represents, warrants and covenants to the Company that:

               (a) Purchase Entirely for Own Account. The shares of the Common
Stock to be acquired by such Member hereunder will be acquired for investment
for such Member's own account, not as a nominee or agent, and not with a present
view to the resale or distribution of any part thereof in violation of federal
or state securities laws, and such Member has no present intention of selling,
granting any participation in, or otherwise distributing the same. By executing
this Agreement, such Member further represents that such Member does not have
any contract, undertaking, agreement or arrangement with any person to sell,
transfer or grant participations, to such person or to any third person, with
respect to the shares of the Common Stock.

               (b) Disclosure of Information. Such Member has received all of
the information that such Member considers necessary or appropriate for deciding
whether to make an investment in the Corporation and acquire the shares of the
Common Stock. Such Member further represents that such Member has had an
opportunity to ask questions of and receive answers from the Company regarding
the Company and the terms and conditions of the Conversion and the Offering.

               (c) Investment Experience. Such Member acknowledges that such
Member is able to fend for himself or herself, can bear the economic risk of the
loss of such Member's entire investment in the shares of the Common Stock and
has such knowledge and experience in financial or business matters that such
Member is capable of evaluating the merits and risks of the investment in the
shares of the Common Stock.

               (d) Accredited Investor. Unless specified otherwise on the
signature page hereto or be delivery to the Company of a notice in writing
before the date hereof, such Member is an "accredited investor" within the
meaning of Rule 501 (as presently in effect) of Regulation D promulgated under
the Securities Act.

               (e) Restricted Securities. Such Member understands that the
shares of the Common Stock are characterized as "restricted securities" under
the federal securities laws inasmuch as the shares are being acquired from the
Corporation in a transaction not involving a public offering, and that under
such laws and applicable regulations such securities may not be resold without
registration under the Securities Act, except in certain limited circumstances.

               (f) Further Limitations on Disposition. Without in any way
limiting the representations set forth above, such Member further agrees not to
make any disposition of all or any portion of any shares of the Common Stock
unless and until: (i) there is then in effect a registration statement under the
Securities Act covering such proposed disposition and such


                                        3

<PAGE>

disposition is made in accordance with such registration statement; or (ii)
registration under the Securities Act is not required pursuant to an applicable
exemption therefrom.

          (g) Legend. It is understood that the certificate representing the
shares of the Common Stock will bear the following legend:

     THE SECURITIES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
     SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"). NO SALE OR DISPOSITION MAY
     BE EFFECTED EXCEPT AS PERMITTED UNDER SAID ACT AND APPLICABLE STATE
     SECURITIES LAWS, PURSUANT TO REGISTRATION OR AN EXEMPTION THEREFROM. THE
     ISSUER OF THESE SECURITIES MAY REQUIRE AN OPINION OF COUNSEL IN FORM AND
     SUBSTANCE REASONABLY SATISFACTORY TO THE ISSUER THAT ANY PROPOSED TRANSFER
     OR RESALE IS IN COMPLIANCE WITH THE ACT.

          (h) Indemnity. Such Member agrees to indemnify each other Member and
the Company from any loss, damage, liability, claims and expenses incurred,
suffered or sustained by any of them as a result of the inaccuracy of any
representation contained in this Section.

in its discretion with the approval of the AG Asset Manager, but in such event
amounts shall be distributed in the same proportions as set


                                        4

Agreement, no officer, director, shareholder, partner, member, employee or agent
of any Member of the Company, Care, and/or the AG Manager shall have any

taken from the Company by such person.
