DELIVERY OF THIS LETTER OF TRANSMITTAL TO AN ADDRESS, OTHER THAN AS SET FORTH

THE INSTRUCTIONS CONTAINED HEREIN SHOULD BE READ CAREFULLY BEFORE THIS LETTER OF

HOLDERS (AS DEFINED HEREIN) WHO WISH TO BE ELIGIBLE TO RECEIVE EXCHANGE NOTES
FOR THEIR OUTSTANDING NOTES PURSUANT TO THE EXCHANGE OFFER MUST VALIDLY TENDER
(AND NOT WITHDRAW) THEIR OUTSTANDING NOTES TO THE EXCHANGE AGENT ON OR PRIOR TO
THE EXPIRATION DATE.

     All capitalized terms used herein and not defined herein shall have the
meaning ascribed to them in the Prospectus.


     By execution hereof, the undersigned acknowledges receipt of the Prospectus
(the "Prospectus"), dated          , 2002, of InSight Health Services Corp., a
Delaware corporation ("InSight"), which, together with this Letter of
Transmittal and the instructions hereto (the "Letter of Transmittal"),
constitute InSight's offer (the "Exchange Offer") to exchange $1,000 in
principal amount of its Registered 9 7/8% Series B Senior Subordinated Notes due
2011 (the "Exchange Notes") for each $1,000 in principal amount of outstanding
9 7/8% Senior Subordinated Notes due 2011 (the "Outstanding Notes" and, together
with the Exchange Notes, the "Notes"), of which $225.0 million aggregate
principal amount was outstanding on the date of the Prospectus. The terms of the
Exchange Notes are



identical in all material respects (including principal amount, interest rate
and maturity) to the terms of the Outstanding Notes for which they may be
exchanged pursuant to the Exchange Offer, except that the Exchange Notes have
been registered under the Securities Act of 1933, as amended (the "Securities
Act"), and, therefore, do not bear legends restricting the transfer thereof.

     InSight reserves the right, at any time or from time to time, to extend the
Exchange Offer at its sole discretion, in which event the term "Expiration Date"
shall mean the latest time and date to which the Exchange Offer is extended.
InSight shall notify the Holders of the Outstanding Notes of any extension by
means of a press release or other public announcement prior to 9:00 a.m., New
York City time, on the next business day after the previously scheduled
Expiration Date.

     This Letter of Transmittal is to be used by Holders of Outstanding Notes
if:

     - a certificate representing Outstanding Notes is to be physically
       delivered to the Exchange Agent along with this Letter of Transmittal by
       Holders; or

     - tender of Outstanding Notes is to be made by the guaranteed delivery
       procedures set forth in "The Exchange Offer -- Guaranteed Delivery
       Procedures" section of the Prospectus. See Instruction 1 to this Letter
       of Transmittal.

     If delivery of the Outstanding Notes is to be made by book-entry transfer
to the account maintained by the Exchange Agent at The Depository Trust Company
(the "Book-Entry Transfer Facility") pursuant to the procedures set forth in
"The Exchange Offer -- Procedures for Tendering" section of the Prospectus by
any financial institution that is a participant in Book-Entry Transfer Facility
whose name appears on a security position listing as the owner of the
Outstanding Notes, this Letter of Transmittal need not be manually executed;
provided, however, that tenders of Outstanding Notes must be effected by sending
electronic instructions to the Book-Entry Transfer Facility through the
Book-Entry Transfer Facility's communication system in accordance with the
procedures mandated by the Book-Entry Transfer Facility's Automated Tender Offer
Program ("ATOP"). To tender Outstanding Notes through ATOP, the electronic
instructions sent to the Book-Entry Transfer Facility and transmitted by the
Book-Entry Transfer Facility to the Exchange Agent must reflect that the
participant acknowledges its receipt of and agrees to be bound by this Letter of
Transmittal.

     DELIVERY OF DOCUMENTATION TO THE BOOK-ENTRY TRANSFER FACILITY DOES NOT
CONSTITUTE DELIVERY TO THE EXCHANGE AGENT.

     The term "Holder" with respect to the Exchange Offer means any person:

     - in whose name Outstanding Notes are registered on the books of InSight or
       any other person who has obtained a properly completed bond power, as
       applicable, from the registered holder; or


     - whose Outstanding Notes are held of record by the Book-Entry Transfer
       Facility (or its nominee), whose name appears on a security position
       listing as the owner of Outstanding Notes (and is a participant in the
       Book-Entry Transfer Facility) and who desires to deliver such Outstanding
       Notes by book-entry transfer at the Book-Entry Transfer Facility.

             ------------------------------------------------------

     The undersigned has completed, executed and delivered this Letter of
Transmittal to indicate the action the undersigned desires to take with respect
to the Exchange Offer.


     HOLDERS (OTHER THAN HOLDERS OF OUTSTANDING NOTES IN BOOK-ENTRY FORM) WHO
WISH TO ACCEPT THE EXCHANGE OFFER AND TENDER THEIR OUTSTANDING NOTES MUST
COMPLETE THIS LETTER OF TRANSMITTAL IN ITS ENTIRETY. HOLDERS OF OUTSTANDING
NOTES IN BOOK-ENTRY FORM WHO WISH TO ACCEPT THE EXCHANGE OFFER AND TENDER THEIR
OUTSTANDING NOTES MUST SEND ELECTRONIC INSTRUCTIONS TO THE BOOK-ENTRY TRANSFER
FACILITY IN ACCORDANCE WITH THE BOOK-ENTRY TRANSFER FACILITY'S ATOP PROCEDURES,
INCLUDING SUCH HOLDERS' ACKNOWLEDGMENT OF ITS RECEIPT OF, AND AGREEMENT TO BE
BOUND BY, THIS LETTER OF TRANSMITTAL.


                                        2


Ladies and Gentlemen:

     The undersigned hereby tenders to InSight the aggregate principal amount of
Outstanding Notes indicated in this Letter of Transmittal, upon the terms and
subject to the conditions set forth in the Prospectus, dated           , 2002
(the "Prospectus"), receipt of which is hereby acknowledged, and in this Letter
of Transmittal.

     Subject to, and effective upon, the acceptance for exchange of the
Outstanding Notes tendered hereby, the undersigned hereby sells, assigns and
transfers to, or upon the order of, InSight all right, title and interest in and
to such Outstanding Notes as are being tendered hereby and hereby irrevocably
constitutes and appoints the Exchange Agent as its agent and attorney-in-fact
with respect to such Outstanding Notes (with full knowledge that the Exchange
Agent acts as agent of InSight for the Outstanding Notes and the Exchange
Notes), with full power of substitution (such power of attorney being an
irrevocable power coupled with an interest), to:

     - deliver such Outstanding Notes in registered certificated form, or
       transfer ownership of such Outstanding Notes through book-entry transfer
       at the Book-Entry Transfer Facility, to or upon the order of InSight,
       upon receipt by the Exchange Agent, as the undersigned's agent, of the
       same aggregate principal amount of Exchange Notes; and

     - present such Outstanding Notes for transfer on the books of InSight and
       receive, for the account of InSight, all benefits and otherwise exercise,
       for the account of InSight, all rights of beneficial ownership of the
       Outstanding Notes tendered hereby in accordance with the terms of the
       Exchange Offer.

     The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, sell, assign and transfer the Outstanding
Notes tendered hereby and that InSight will acquire good, marketable and
unencumbered title thereto, free and clear of all security interests, liens,
restrictions, charges, encumbrances, conditional sale agreements or other
obligations relating to their sale or transfer, and not subject to any adverse
claim when the same are accepted by InSight. The undersigned also represents and
warrants that it will, upon request, execute and deliver any additional
documents deemed by the Exchange Agent or InSight to be necessary or desirable
to complete the sale, exchange, assignment and transfer of tendered Outstanding
Notes.

     The undersigned also acknowledges that this Exchange Offer is being made
based upon InSight's understanding of an interpretation by the staff of the
Securities and Exchange Commission (the "SEC") as set forth in non-action
letters issued to third parties unrelated to InSight, including Exxon Capital
Holdings Corporation (available May 13, 1988), Morgan Stanley & Co. Incorporated
(available June 5, 1991) and Shearman & Sterling (available July 2, 1993) (the
"SEC No-Action Letters"), that the Exchange Notes issued in exchange for the
Outstanding Notes pursuant to the Exchange Offer may be offered for resale,
resold and otherwise transferred by a Holder (other than a broker-dealer who
acquires such Exchange Notes directly from InSight for resale pursuant to Rule
144A under the Securities Act or any other available exemption under the
Securities Act or any such Holder that is an "affiliate" of InSight or of any of
the guarantors under the indenture relating to the Notes (the "Guarantors")
within the meaning of Rule 405 under the Securities Act), without compliance
with the registration and prospectus delivery provisions of the Securities Act,
provided that such Exchange Notes are acquired in the ordinary course of such
Holder's business and such Holder is not engaged in, and does not intend to
engage in, a distribution of such Exchange Notes and has no arrangement with any
person to participate in the distribution of such Exchange Notes. The SEC has
not, however, considered the Exchange Offer in the context of a no-action
letter, and there can be no assurance that the staff of the SEC would make a
similar determination with respect to the Exchange Offer as in the SEC No-Action
Letters.

     The undersigned hereby further represents that:

     - the Exchange Notes acquired in exchange for Outstanding Notes tendered
       hereby will have been acquired in the ordinary course of business of the
       person receiving such Exchange Notes, whether or not such person is the
       undersigned,

     - neither the undersigned nor any such other person has an arrangement or
       understanding with any person to participate in the distribution of such
       Exchange Notes and neither the holder of such Outstanding Notes nor any
       such person is engaging in, or intends to engage in, the distribution of
       such Exchange Notes,

     - except as indicated herein, neither the undersigned nor any such other
       person is an "affiliate" of InSight within the meaning of Rule 405 under
       the Securities Act or, if such holder or any such other person is an
       affiliate of

                                        3


       InSight, that such holder or such other person will comply with the
       registration and prospectus delivery requirements of the Securities Act
       to the extent applicable. The undersigned has read and agrees to all of
       the terms of the Exchange Offer as described in the Prospectus and
       herein, and


     - neither the undersigned nor any such other person is acting on behalf of
       any person or entity that could not truthfully make these
       representations.


     If the undersigned is a broker-dealer that will receive Exchange Notes for
its own account in exchange for Outstanding Notes, it represents that the
Outstanding Notes to be exchanged for the Exchange Notes were acquired by it as
a result of market-making or other trading activities (a "Participating
Broker-Dealer") and acknowledges that it has not entered into an arrangement or
understanding with InSight or any "affiliate" of InSight within the meaning of
Rule 405 under the Securities Act to distribute the Exchange Notes to be
received in the Exchange Offer and that it will deliver the Prospectus in
connection with any resale of such Exchange Notes; however, by so acknowledging
and by delivering the Prospectus, the undersigned or such beneficial owner will
not be deemed to admit that it is an "underwriter" within the meaning of the
Securities Act.

     InSight has agreed that, subject to the provisions of the Registration
Rights Agreement, dated as of October 30, 2001, by and among InSight, InSight
Health Services Holdings Corp., the Subsidiary Guarantors named therein, Banc of
America Securities LLC and First Union Securities, Inc., the Prospectus, as it
may be amended or supplemented from time to time, may be used by a Participating
Broker-Dealer in connection with resales of Exchange Notes received in exchange
for Outstanding Notes acquired by such Participating Broker-Dealer for its own
account as a result of market-making or other trading activities, for a period
ending 90 days after the Expiration Date or, if earlier, when all such Exchange
Notes have been disposed of by such Participating Broker-Dealer. In that regard,
each Participating Broker-Dealer by tendering such Outstanding Notes and
executing this Letter of Transmittal, agrees that, upon receipt of notice from
InSight of the occurrence of any event or the discovery of any fact which makes
any statement contained or incorporated by reference in the Prospectus untrue in
any material respect or which causes the Prospectus to omit to state a material
fact necessary in order to make the statements contained or incorporated by
reference therein, in light of the circumstances under which they were made, not
misleading, such Participating Broker-Dealer will suspend the sale of Exchange
Notes pursuant to the Prospectus until InSight has amended or supplemented the
Prospectus to correct such misstatement or omission and has furnished copies of
the amended or supplemented Prospectus to the Participating Broker-Dealer or
InSight has given notice that the sale of the Exchange Notes may be resumed, as
the case may be. If InSight gives such notice to suspend the sale of the
Exchange Notes, it shall extend the 90-day period referred to above during which
Participating Broker-Dealers are entitled to use the Prospectus in connection
with the resale of Exchange Notes by the number of days during the period from
and including the date of the giving of such notice to and including the date
when Participating Broker-Dealers shall have received copies of the supplemented
or amended Prospectus necessary to permit resales of the Exchange Notes or to
and including the date on which InSight has given notice that the sale of
Exchange Notes may be resumed, as the case may be.

     The undersigned will, upon request, execute and deliver any additional
documents deemed by InSight or the Exchange Agent to be necessary or desirable
to complete the sale, assignment and transfer of the Outstanding Notes tendered
hereby. All authority conferred or agreed to be conferred in this Letter of
Transmittal and every obligation of the undersigned hereunder shall be binding
upon the successors, assigns, heirs, executors, administrators, trustees in
bankruptcy and legal representatives of the undersigned and shall not be
affected by, and shall survive, the death or incapacity of the undersigned. This
tender may be withdrawn only in accordance with the procedures set forth in "The
Exchange Offer -- Withdrawal of Tenders" section of the Prospectus.

     For purposes of the Exchange Offer, InSight shall be deemed to have
accepted validly tendered Outstanding Notes when InSight has given oral or
written notice thereof to the Exchange Agent. If any tendered Outstanding Notes
are not accepted for exchange pursuant to the Exchange Offer for any reason,
certificates for any such unaccepted Outstanding Notes will be returned (except
as noted herein with respect to tenders through the Book-Entry Transfer
Facility), without expense, to the undersigned at the address shown below or at
a different address as may be indicated herein under "Special Issuance
Instructions" as promptly as practicable after the Expiration Date.

     The undersigned understands that tender of the Outstanding Notes pursuant
to any one of the procedures described under "The Exchange Offer -- Procedures
for Tendering " in the Prospectus and in the instructions hereto

                                        4


will constitute a binding agreement between the undersigned and InSight in
accordance with the terms and subject to the conditions of the Exchange Offer.

     The undersigned recognizes that, under certain circumstances set forth in
the Prospectus under "The Exchange Offer -- Conditions," InSight may not be
required to accept for exchange any of the Outstanding Notes tendered.
Outstanding Notes not accepted for exchange or withdrawn will be returned to the
undersigned at the address set forth below unless otherwise indicated herein
under "Special Delivery Instructions."

     Unless otherwise indicated herein under "Special Issuance Instructions,"
please deliver the Exchange Notes (and, if applicable, substitute certificates
representing Outstanding Notes for any Outstanding Notes not exchanged) in the
name of the undersigned or, in the case of a book-entry delivery of Outstanding
Notes, please credit the account indicated above maintained at the Book-Entry
Transfer Facility. Similarly, unless otherwise indicated under the box entitled
"Special Delivery Instructions" below, please send the Exchange Notes (and, if
applicable, substitute certificates representing Outstanding Notes for any
Outstanding Notes not exchanged) to the undersigned at the address shown above
in the box entitled "Description of Outstanding Notes." The undersigned
recognizes that InSight has no obligation pursuant to the "Special Issuance
Instructions" and "Special Delivery Instructions" to transfer any Outstanding
Notes from the name of the registered holder(s) thereof if InSight does not
accept for exchange any of the Outstanding Notes so tendered.

     The instructions included with this Letter of Transmittal must be followed.
Questions and requests for assistance or for additional copies of the
Prospectus, this Letter of Transmittal and the accompanying Notice of Guaranteed
Delivery (the "Notice of Guaranteed Delivery") may be directed to the Exchange
Agent. PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY.

     THE UNDERSIGNED, BY COMPLETING THE BOX ENTITLED "DESCRIPTION OF OUTSTANDING
NOTES" AND SIGNING THIS LETTER OF TRANSMITTAL AND DELIVERING SUCH OUTSTANDING
NOTES AND THIS LETTER OF TRANSMITTAL TO THE EXCHANGE AGENT, WILL BE DEEMED TO

                         FORMING PART OF THE TERMS AND
                        CONDITIONS OF THE EXCHANGE OFFER

     1. DELIVERY OF THIS LETTER OF TRANSMITTAL AND OUTSTANDING NOTES; GUARANTEED
DELIVERY PROCEDURES.  The certificates for the tendered Outstanding Notes (or a
timely confirmation of the book-entry transfer of Outstanding Notes into the
Exchange Agent's account at The Book-Entry Transfer Facility of all Outstanding
Notes delivered electronically), as well as a properly completed and duly
executed copy of this Letter of Transmittal (unless tenders are validly made by
book-entry transfer) and any other documents required by this Letter of
Transmittal must be received by the Exchange Agent at its address set forth
herein prior to 5:00 P.M., New York City time, on the Expiration Date.
Outstanding Notes may only be tendered in a principal amount of $1,000 and any
integral multiple thereof.

     Holders of Outstanding Notes whose certificates for Outstanding Notes are
not immediately available or who cannot deliver their certificates and all other
required documentation to the Exchange Agent on or prior to the Expiration Date,
or who cannot complete the procedure for book-entry transfer on a timely basis,
may tender their Outstanding Notes pursuant to the guaranteed delivery
procedures set forth in "The Exchange Offer -- Guaranteed Delivery Procedures"
section of the Prospectus. Pursuant to such procedures:

     - such tender must be made through an Eligible Institution (as defined
       below) and the Holder must sign a Notice of Guaranteed Delivery;

     - on or prior to the Expiration Date, the Exchange Agent must receive from
       such Eligible Institution a properly completed and duly executed Notice
       of Guaranteed Delivery, substantially in the form provided by InSight (by
       facsimile transmission (receipt confirmed by telephone and an original
       delivered by guaranteed overnight courier, mail or hand delivery),
       setting forth the name and address of the holder of Outstanding Notes,
       the certificate number(s) of such Outstanding Notes (if applicable) and
       the amount of Outstanding Notes tendered, stating that the tender is
       being made thereby and guaranteeing that, within five business days after
       the Expiration Date, this Letter of Transmittal (or a facsimile thereof),
       together with the certificates for all physically tendered Outstanding
       Notes in proper form for transfer, or a Book-Entry Confirmation of such
       Outstanding Notes, and any other documentation required by this Letter of
       Transmittal will be deposited by the Eligible Institution with the
       Exchange Agent; and

     - a properly executed Letter of Transmittal (or copy thereof), as well as
       the certificates for all physically tendered Outstanding Notes in proper
       form for transfer or a Book-Entry Confirmation of such Outstanding Notes,
       as the case may be, and all other documentation required by this Letter
       of Transmittal, must be received by the Exchange Agent within five
       business days after the Expiration Date.

     All questions as to the validity, form, eligibility (including time of
receipt), acceptance and withdrawal of tendered Outstanding Notes will be
determined by InSight in its sole discretion, which determination will be final
and binding. InSight reserves the absolute right to reject any and all
Outstanding Notes not properly tendered or any Outstanding Notes InSight's
acceptance of which would, in the opinion of counsel for InSight, be unlawful.
InSight also reserves the right to waive any defects, irregularities or
conditions of tender as to particular Outstanding Notes. InSight's
interpretation of the terms and conditions of the Exchange Offer (including the
instructions in this Letter of Transmittal) will be final and binding on all
parties. Unless waived, any defects or irregularities in connection with tenders
of Outstanding Notes must be cured within such time as InSight shall determine.
Neither InSight, the Exchange Agent nor any other person shall be under any duty
to give notification of defects or irregularities with respect to tenders of
Outstanding Notes, nor shall any of them incur any liability for failure to give
such notification. Tenders of Outstanding Notes will not be deemed to have been
made until such defects or irregularities have been cured or waived and will be
returned by the Exchange Agent to the tendering Holders of Outstanding Notes,
unless otherwise provided in this Letter of Transmittal, as soon as practicable
following the Expiration Date unless the Exchange Offer is extended.

     THE METHOD OF DELIVERY OF THIS LETTER OF TRANSMITTAL, THE OUTSTANDING NOTES
AND ALL OTHER REQUIRED DOCUMENTATION IS AT THE ELECTION AND RISK OF THE
TENDERING HOLDERS, BUT THE DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY
                                        12

RECOMMENDED THAT HOLDERS USE AN OVERNIGHT OR HAND DELIVERY SERVICE, PROPERLY
INSURED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE DELIVERY TO
THE EXCHANGE AGENT ON OR PRIOR TO 5:00 P.M., NEW YORK CITY TIME, ON THE
EXPIRATION DATE. DO NOT SEND THIS LETTER OF TRANSMITTAL OR ANY OUTSTANDING NOTES
TO THE ISSUER.

     2. TENDER BY HOLDER.  Only a holder or acting Holder of Outstanding Notes
may tender such Outstanding Notes in the Exchange Offer. Any beneficial owner of
Outstanding Notes who is not the registered holder and who wishes to tender
should arrange with such Holder to execute and deliver this Letter of
Transmittal on such owner's behalf or must, prior to completing and executing
this Letter of Transmittal and delivering such Outstanding Notes, either make
appropriate arrangements to register ownership of the Outstanding Notes in such
owner's name or obtain a properly completed bond power from the registered
Holder.

     See "The Exchange Offer" section of the Prospectus.

     3. PARTIAL TENDERS (NOT APPLICABLE TO HOLDERS OF OUTSTANDING NOTES WHO
TENDER BY BOOK-ENTRY TRANSFER); WITHDRAWAL RIGHTS.  Tenders of Outstanding Notes
will be accepted only in the principal amount of $1,000 and integral multiples
thereof. If less than all of the Outstanding Notes evidenced by a submitted
certificate are to be tendered, the tendering Holder(s) should fill in the
aggregate principal amount of Outstanding Notes to be tendered in the box above
entitled "Description of Outstanding Notes -- Aggregate Principal Amount
Tendered." A reissued certificate representing the balance of nontendered
Outstanding Notes will be sent to such tendering Holder, unless otherwise
provided in the appropriate box on this Letter of Transmittal, promptly after
the Expiration Date. ALL OF THE OUTSTANDING NOTES DELIVERED TO THE EXCHANGE
AGENT WILL BE DEEMED TO HAVE BEEN TENDERED UNLESS OTHERWISE INDICATED.

     Any Holder who has tendered Outstanding Notes may withdraw the tender by
delivering written notice of withdrawal (which may be sent by facsimile
transmission (receipt confirmed by telephone and an original delivered by
guaranteed overnight courier), mail or hand delivery) to the Exchange Agent on
or prior to the Expiration Date. For a withdrawal to be effective, a written
notice of withdrawal must be received by the Exchange Agent at its address set
forth herein on or prior to the Expiration Date. Any such notice of withdrawal
must:

     - specify the name of the person having tendered the Outstanding Notes to
       be withdrawn (the "Depositor"),

     - identify the Outstanding Notes to be withdrawn (including the certificate
       number or numbers and principal amount of such Outstanding Notes),

     - be timely received and signed by the Holder in the same manner as the
       original signature on the Letter of Transmittal by which such Outstanding
       Notes were tendered or as otherwise set forth in Instruction 4 below
       (including any required signature guarantees), or be accompanied by
       documents of transfer sufficient to have the Trustee (as defined in the
       Prospectus) register the transfer of such Outstanding Notes pursuant to
       the terms of the Indenture into the name of the person withdrawing the
       tender,

     - contain a statement that the Holder is withdrawing its election to have
       such Outstanding Notes exchanged, and

     - specify the name in which any such Outstanding Notes are to be
       registered, if different from that of the Depositor.

     If Outstanding Notes have been tendered pursuant to the procedure for
book-entry transfer, any notice of withdrawal must specify the name and number
of the account at the Book-Entry Transfer Facility to be credited with the
withdrawn Outstanding Notes or otherwise comply with the Book-Entry Transfer
Facility's procedures. See "The Exchange Offer -- Withdrawal of Tenders" section
of the Prospectus.

     Withdrawals of tenders of Outstanding Notes may not be rescinded.
Outstanding Notes properly withdrawn will not be deemed to have been validly
tendered for purposes of the Exchange Offer, and no Exchange Notes will be
issued with respect thereto unless the Outstanding Notes so withdrawn are
validly retendered. Properly withdrawn

                                        13


Outstanding Notes may be retendered at any subsequent time on or prior to the
Expiration Date by following the procedures described in "The Exchange
Offer -- Procedures for Tendering" section of the Prospectus.

     You may retender properly withdrawn Outstanding Notes in this exchange by
following the procedures above at any time on or before the Expiration Date.

     4. SIGNATURES ON THIS LETTER OF TRANSMITTAL; BOND POWERS AND ENDORSEMENTS;
GUARANTEE OF SIGNATURES.  If this Letter of Transmittal is signed by the Holder
of the Outstanding Notes tendered hereby, the signature must correspond exactly
with the name as written on the face of the certificates or on a securities
position listing without any change whatsoever.

     If any tendered Outstanding Notes are owned of record by two or more joint
owners, all of such owners must sign this Letter of Transmittal.

     If any tendered Outstanding Notes are registered in different names on
several certificates or securities positions listings, it will be necessary to
complete, sign and submit as many separate copies of this Letter of Transmittal
as there are different registrations.

     The signatures on this Letter of Transmittal or a notice of withdrawal, as
the case may be, must be guaranteed by an Eligible Institution unless the
Outstanding Notes tendered pursuant hereto are tendered (i) by a registered
Holder of the Outstanding Notes who has not completed the box entitled "Special
Issuance Instructions" or "Special Delivery Instructions" in this Letter of
Transmittal or (ii) for the account of an Eligible Institution. In the event
that the signatures in this Letter of Transmittal or a notice of withdrawal, as
the case may be, are required to be guaranteed, such guarantees must be by a
firm which is a member of a registered national securities exchange or a member
of the National Association of Securities Dealers, Inc., a commercial bank or
trust company having an office or correspondent in the United States, or another
"eligible guarantor institution" within the meaning of Rule 17Ad-15 under the
Securities Exchange Act of 1934, as amended (collectively, "Eligible
Institutions").

     If this Letter of Transmittal is signed by a person other than the Holder
of any Outstanding Notes listed therein, such Outstanding Notes must be endorsed
or accompanied by a properly completed bond power signed by such Holder exactly
as the name or names of such Holder or Holders appear(s) on such Outstanding
Notes with the signatures on the Outstanding Notes or the bond power guaranteed
by an Eligible Institution.

     If this Letter of Transmittal or any Outstanding Notes or assignments or
bond powers are signed by trustees, executors, administrators, guardians,
attorneys-in-fact, officers of corporations or others acting in a fiduciary or
representative capacity, such persons should so indicate when signing, and,
unless waived by InSight, evidence satisfactory to InSight of their authority to
so act must be submitted with this Letter of Transmittal.

     5. SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS.  Tendering Holders of
Outstanding Notes should indicate in the applicable box the name and address to
which Exchange Notes issued pursuant to the Exchange Offer and/or substitute
certificates evidencing Outstanding Notes not exchanged are to be issued or
sent, if different from the name or address of the person signing this Letter of
Transmittal. In the case of issuance in a different name, the Tax Identification
Number ("TIN") or Social Security Number of the person named must also be
indicated. A Holder of Outstanding Notes tendering Outstanding Notes by
book-entry transfer may request that Outstanding Notes not exchanged be credited
to such account maintained at the Book-Entry Transfer Facility as such Holder
may designate hereon. If no such instructions are given, such Outstanding Notes
not exchanged will be returned to the name or address of the person signing this
Letter of Transmittal or credited to the account listed beneath the box entitled
"Description of Outstanding Notes," as the case may be.

     6. TAX IDENTIFICATION NUMBER; SUBSTITUTE FORM W-9.  Each tendering Holder
whose Outstanding Notes are accepted for exchange must provide InSight (as
payor) with such Holder's correct TIN on Substitute Form W-9, made a part of
this Letter of Transmittal, which, in the case of a tendering Holder who is an
individual, is his or her Social Security Number. If InSight is not provided
with the current TIN or an adequate basis for an exemption, such tendering
Holder may be subject to a $50 penalty imposed by the Internal Revenue Service.
In addition, delivery to such tendering Holder of Exchange Notes may be subject
to backup withholding in an amount equal to 30% (subject to adjustment in future
years) of all reportable payments made after the exchange. If withholding
results in an overpayment of taxes, a refund may be obtained.

                                        14


     Exempt Holders of Outstanding Notes (including, among others, all
corporations and certain foreign individuals) are not subject to these backup
withholding and reporting requirements. See the attached Guidelines of
Certification of Taxpayer Identification Number on Substitute Form W-9 (the "W-9
Guidelines") for additional instructions.

     To prevent backup withholding, each tendering Holder of Outstanding Notes
must provide its correct TIN by completing the Substitute Form W-9 set forth in
this Letter of Transmittal, certifying that the TIN provided is correct (or that
such Holder is awaiting a TIN) and that:

     - the Holder is exempt from backup withholding,

     - the Holder has not been notified by the Internal Revenue Service that
       such Holder is subject to backup withholding as a result of a failure to
       report all interest or dividends or

     - the Internal Revenue Service has notified the Holder that such Holder is
       no longer subject to backup withholding.

     If the tendering Holder of Outstanding Notes is a nonresident alien or
foreign entity not subject to backup withholding, such Holder must give InSight
a completed Form W-8 BEN, Certificate of Foreign Status. These forms may be
obtained from the Exchange Agent. If the Outstanding Notes are in more than one
name or are not in the name of the actual owner, such Holder should consult the
W-9 Guidelines for information on which TIN to report. If such Holder does not
have a TIN, such Holder should consult the W-9 Guidelines for instructions on
applying for a TIN, check the box in Part 3 of the Substitute Form W-9 and write
"applied for" in lieu of its TIN. Note: Checking such box and writing "applied
for" on the form means that such Holder has already applied for a TIN or that
such Holder intends to apply for one in the near future. If such Holder does not
provide its TIN to InSight within 60 days, backup withholding will begin and
continue until such Holder furnishes its TIN to InSight.

     7. TRANSFER TAXES.  InSight will pay all transfer taxes, if any, applicable
to the transfer of Outstanding Notes to it or its order pursuant to the Exchange
Offer. If, however, Exchange Notes and/or substitute Outstanding Notes not
exchanged are to be delivered to, or are to be registered or issued in the name
of, any person other than the Holder of the Outstanding Notes tendered hereby,
or if tendered Outstanding Notes are registered in the name of any person other
than the person signing this Letter of Transmittal, or if a transfer tax is
imposed for any reason other than the transfer of Outstanding Notes to InSight
or its order pursuant to the Exchange Offer, the amount of any such transfer
taxes (whether imposed on the Holder or any other persons) will be payable by
the tendering Holder. If satisfactory evidence of payment of such taxes or
exemption therefrom is not submitted herewith, the amount of such transfer taxes
will be billed directly to such tendering Holder.

TRANSMITTAL.

     8. WAIVER OF CONDITIONS.  InSight reserves the absolute right to waive
satisfaction of any or all conditions enumerated in the Prospectus.

     9. DETERMINATION OF VALIDITY.  InSight will determine, in its sole
discretion, all questions as to the form of documents, validity, eligibility
(including time of receipt) and acceptance for exchange of any tender of
Outstanding Notes, which determination shall be final and binding on all
parties. InSight reserves the absolute right to reject any and all tenders
determined by it not to be in proper form or the acceptance of which, or
exchange for which, may be unlawful. InSight also reserves the absolute right,
subject to applicable law, to waive any of the conditions of the Exchange Offer
set forth in the Prospectus under the caption "The Exchange Offer -- Conditions"
or any conditions or irregularity in any tender of Outstanding Notes of any
particular Holder whether or not similar conditions or irregularities are waived
in the case of other Holders.

     InSight's interpretation of the terms and conditions of the Exchange Offer
(including this Letter of Transmittal and the instructions hereto) will be final
and binding. No tender of Outstanding Notes will be deemed to have been validly
made until all irregularities with respect to such tender have been cured or

     10. NO CONDITIONAL TENDERS.  No alternative, conditional, irregular or
contingent tenders will be accepted. All tendering Holders of Outstanding Notes,
by execution of this Letter of Transmittal, shall waive any right to receive
notice of the acceptance of their Outstanding Notes for exchange.

     11. MUTILATED, LOST, STOLEN OR DESTROYED OUTSTANDING NOTES.  Any Holder
whose Outstanding Notes have been mutilated, lost, stolen or destroyed should

documents cannot be processed until the Outstanding Notes have been replaced.
