CUSIP No. 45821T 10 8                 13D/A                          Page 3 of 7


         Pursuant to Rule 13d-2(a) promulgated under the Securities Exchange Act
of 1934 ("Exchange Act"), Reporting Person hereby files this Amendment No. 4 to
Schedule 13D ("Amendment") with the Securities and Exchange Commission
("Commission"). This Amendment amends and supplements the Schedule 13D
originally filed with the Commission on July 12, 2007 and amended July 24, 2008,
November 6, 2008 and February 2, 2009 relating to the common stock of Issuer.

         All capitalized terms used in this Amendment and not otherwise defined
herein have the meanings ascribed to them in the original Schedule 13D, as
amended (the "Schedule 13D"). The item numbers and responses thereto below are
in accordance with the requirements of Schedule 13D. All Rule citations used in
the Schedule 13D and this Amendment are to the rules and regulations promulgated
under the Exchange Act.

ITEM 4.           PURPOSE OF TRANSACTION.

         Item 4 of the Schedule 13D is amended and supplemented to reflect the
occurrence of the following:

         On March 6, 2009, Reporting Person entered into Amendment No. 2 to the
Securities Purchase Agreement by and among Issuer, Reporting Person and
Chaudhuri, to amend the Securities Purchase Agreement dated July 18, 2008, as
previously amended January 30, 2009 (as amended to date, the "SPA"). Amendment
No. 2 to the SPA clarified that each of Reporting Person's and Chaudhuri's
pre-emptive rights under the SPA to maintain their respective levels of
ownership of Issuer's common stock by acquiring additional equity securities
concurrent with future issuances by Issuer of equity securities or rights
convertible into or exercisable for equity securities (other than issuances of
Additional Shares, shares underlying the Purchase Right or shares issued to
Chaudhuri on July 18, 2008 upon exercise of warrants) covers situations where
issuance of securities or rights would result in dilution of Reporting Person's
or Chaudhuri's (a) beneficial ownership for Section 13(d) purposes on a
fully-diluted basis and/or (b) ownership of outstanding voting securities of
Issuer to less than the greater of (i) 5.0% (in the case of Reporting Person) or
51.0% (in the case of Chaudhuri) of the outstanding voting shares of Issuer and
(ii) his respective percentage ownership of the outstanding voting shares of
Issuer prior to the issuance.

         On March 25, 2009, Reporting Person entered into a Settlement
Agreement, General Release and Covenant Not to Sue ("First Settlement") among
Issuer, Reporting Person, Chaudhuri, Anil V. Shah ("Shah"), Orange County
Physicians Investment Network, LLC ("OC-PIN"), Bruce Mogel, Pacific Coast
Holdings Investment, LLC ("PCHI"), West Coast Holdings, LLC, ""Ganesha Realty,
LLC, ""and Medical Capital Corporation, Medical Provider Financial Corporation
I, Medical Provider Financial Corporation II and Medical Provider Financial
Corporation III (together, "Medical Capital"). Pursuant to the First Settlement,
Thomas released various claims and disputes with and against the parties to the
First Agreement.



CUSIP No. 45821T 10 8                 13D/A                          Page 4 of 7


         As required by the First Settlement and by another settlement agreement
executed by Chaudhuri, Shah, OC-PIN, certain members of OC-PIN ("OC-PIN
Members") and certain other persons and entities other than Reporting Person
(the "Second Settlement", and together, with the First Settlement, the
"Settlement Agreements"), Issuer entered into three separate stock purchase
agreements (each an "April Purchase Agreement") with each of (i) Chaudhuri, (ii)
Shah and (iii) OC-PIN and OC-PIN Members (the persons and entities in clauses
(i), (ii) and (iii) are referred to as the "Potential April Purchasers"). The
April Purchase Agreements cover an aggregate of 60,000,000 shares of common
stock of Issuer that may be purchased by the Potential April Purchasers at a
purchase price of $0.03 per share.

         The closing of the April Purchase Agreements is scheduled for May 18,
2009. The closing will not occur if none of the Potential April Purchasers
elects to purchase shares under their respective April Purchase Agreement. The
closing date may be extended if Issuer does not have sufficient authorized
capital to issue all of the shares, if any, elected to be purchased under the
April Purchase Agreements. Issuer is in the process of increasing its authorized
capital from 400,000,000 shares of common stock to 500,000,000 shares of common
stock in order to accommodate purchases under the April Purchase Agreements and
other agreements, including the SPA. Issuer has agreed to use any net proceeds
from sales under the April Purchase Agreement to pay down the principal balance
of a note owed to Medical Provider Financial Corporation III in the original
principal amount of $10.7 million.

         The Settlement Agreements resolved various pending and threatened
litigation matters and disputes among the various parties thereto and made or
required certain amendments to Issuer's secured loan arrangements with Medical
Capital and certain real property lease obligations of Issuer.

         In addition, among other things, the First Settlement required Issuer
to amend its bylaws in order to: (a) fix the authorized number of directors at
seven (previously it was a range of three to seven) and (b) provide that,
effective immediately after Issuer's 2009 annual meeting, a stockholder who owns
15% or more of the voting stock of Issuer is entitled to call one special
stockholders meeting per calendar year. Also, the First Settlement requires
Issuer to appoint an OC-PIN representative selected by a majority-in-interest of
OC-PIN Members to fill until Issuer's 2009 annual meeting the board seat to be
vacated by Ken Westbrook. The First Settlement also contains an agreement by
Shah that for two years after April 2, 2009, Shah will not accept any nomination
or appointment or serve as a director, officer or employee of Issuer, so long as
Issuer keeps current in its payment of certain real property leases.

         In connection with the Settlement Agreements, Chaudhuri, Shah, OC-PIN
and certain OC-PIN Members entered into a Shareholders Agreement dated April 2,
2009. Under the Shareholders Agreement, Chaudhuri, OC-PIN and Shah agreed to
various voting rights and obligations, and certain tag along purchase rights
with respect to shares of Issuer's common stock. Those rights and obligations
are described in further detail in Chaudhuri's Schedule 13D filings.



CUSIP No. 45821T 10 8                 13D/A                          Page 5 of 7


         Reporting Person may exercise his pre-emptive rights under the SPA as
opportunities present themselves. Except as set forth in the Schedule 13D, as
amended by this Amendment, Reporting Person currently has no plans or proposals
that relate to or would result in any of the following matters referred to in
paragraphs (a) through (j), inclusive, of Item 4 of Schedule 13D: (a) the
acquisition by any person of additional securities of Issuer, or the disposition
of securities of Issuer; (b) any extraordinary corporate transaction, such as a
merger, reorganization or liquidation, involving Issuer or any of its
subsidiaries; (c) any sale or transfer of a material amount of assets of Issuer
or any of its subsidiaries; (d) any change in the present board of directors or
management of Issuer, including any plans or proposals to change the number or
term of directors or to fill any existing vacancies on the board; (e) any
material change in the present capitalization or dividend policy of Issuer; (f)
any other material change in Issuer's business or corporate structure; (g) any
changes in Issuer's charter, bylaws or instruments corresponding thereto, or
other actions which may impede the acquisition of control of Issuer by any
person; (h) causing a class of securities of Issuer to be delisted from a
national securities exchange or to cease to be authorized to be quoted in an
inter-dealer quotation system of a registered national securities association;
(i) a class of equity securities of Issuer becoming eligible for termination of
the registration pursuant to Section 12(g)(4) of the Exchange Act; or (j) any
action similar to any of those enumerated above. Reporting Person, however, may
at any time and from time to time, review or reconsider his position with
respect to any of such matters.

         References to, and descriptions of, the SPA, Amendment No. 2 to the
SPA, and the First Settlement in this Item 4 are qualified in their entirety by
reference to the full text of those documents, which are attached or
incorporated by reference as exhibits hereto. The Second Settlement, the April
Purchase Agreements and the Shareholders Agreement, as to each of which
Reporting Person is not a party, are attached or incorporated by reference into
Chaudhuri's Schedule 13D filings.

ITEM 6.           CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH
                  RESPECT TO SECURITIES OF THE ISSUER.

         Item 6 of the Schedule 13D is amended and supplemented to include the
