  The undersigned acknowledges receipt of the Prospectus dated ____________,
2001 (the "Prospectus") of AmerisourceBergen Corporation (the "Company") and
this Letter of Transmittal (the "Letter of Transmittal"), which together
constitute the Company's Offer to Exchange (the "Exchange Offer") $500,000,000
principal amount of its 8 1/8% Senior Notes due 2008 (the "Exchange Notes"),
which have been registered under the Securities Act of 1933, as amended (the
"Securities Act"), pursuant to a Registration Statement of which the Prospectus
is a part, for each $1,000 principal amount of its outstanding 8 1/8% Senior
Notes due 2008 (the "Existing Notes"), of which $500,000,000 principal amount is
outstanding, upon the terms and conditions set forth in the Prospectus and this
Letter of Transmittal. Other capitalized terms used but not defined herein have
the meaning given to them in the Prospectus.

  For each Existing Note accepted for exchange, the holder of such Existing Note
will receive an Exchange Note having a principal amount equal to that of the
surrendered Existing Note.  Interest on the Exchange Notes will accrue from the
last interest payment date on which interest was paid on the Existing Notes
surrendered in exchange therefor.  Holders of Existing Notes accepted for
exchange will be deemed to have waived the right to receive any other payments
or accrued interest on the Existing Notes.  The Company reserves the right, at
any time or from time to time, to extend the Exchange Offer at its discretion,
in which event the term "Expiration Date" shall mean the latest time and date to
which the


Exchange Offer is extended. The Company shall notify holders of the Existing
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 if:  (i) certificates
representing Existing Notes are to be physically delivered to the Exchange Agent
herewith by Holders; (ii) tender of Existing Notes is to be made by book-entry
transfer to the Exchange Agent's account at The Depository Trust Company
("DTC"), pursuant to the procedures set forth in the Prospectus under "The
Exchange Offer -- Procedures for Tendering Existing Notes" by any financial
institution that is a participant in DTC and whose name appears on a security
position listing as the owner of Existing Notes or (iii) tender of Existing
Notes is to be made according to the guaranteed delivery procedures set forth in
the Prospectus under "The Exchange Offer -- Guaranteed Delivery Procedures."
DELIVERY OF DOCUMENTS TO DTC DOES NOT CONSTITUTE DELIVERY TO THE EXCHANGE AGENT.

  The term "Holder" with respect to the Exchange Offer means any person: (i) in
whose name Existing Notes are registered on the books of the Company or any
other person who has obtained a properly completed bond power from the
registered Holder, or (ii) whose Existing Notes are held of record by DTC (or
its nominee) who desires to deliver such Existing Notes by book-entry transfer
at DTC.  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 of Existing Notes that are tendering by book-entry transfer to the
Exchange Agent's account at DTC can execute the tender through the DTC Automated
Tender Offer Program ("ATOP"), for which the transaction will be eligible. DTC
participants that are accepting the Exchange Offer must transmit their
acceptance to DTC, which will verify the acceptance and execute a book-entry
delivery to the Exchange Agent's DTC account. DTC will then send an Agent's
Message to the Exchange Agent for its acceptance.  DTC participants may also
accept the Exchange Offer prior to the Expiration Date by submitting a Notice of
Guaranteed Delivery or Agent's Message relating thereto as described herein
under Instruction 1, "Guaranteed Delivery Procedures."

  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 or the Notice of Guaranteed Delivery may
be directed to the Exchange Agent. See Instruction 11 herein.


        HOLDERS WHO WISH TO ACCEPT THE EXCHANGE OFFER AND TENDER THEIR
        EXISTING NOTES MUST COMPLETE THIS LETTER OF TRANSMITTAL IN ITS
           ENTIRETY.  PLEASE READ THIS ENTIRE LETTER OF TRANSMITTAL

    Ladies and Gentlemen:

    Subject to the terms and conditions of the Exchange Offer, the undersigned
hereby tenders to the Company the principal amount of Existing Notes indicated
above.  Subject to and effective upon the acceptance for exchange of the
principal amount of Existing Notes tendered in accordance with this Letter of
Transmittal, the undersigned sells, assigns and transfers to, or upon the order
of, the Company all right, title and interest in and to the Existing Notes
tendered hereby.  The undersigned hereby irrevocably constitutes and appoints
the Exchange Agent its agent and attorney-in-fact (with full knowledge that the
Exchange Agent also acts as the agent of the Company and as Trustee under the
Indenture for the Existing Notes and Exchange Notes) with respect to the
tendered Existing Notes with full power of substitution to (i) deliver
certificates for such Existing Notes to the Company, or transfer ownership of
such Existing Notes on the account books maintained by DTC and deliver all
accompanying evidence of transfer and authenticity to, or upon the order of, the
Company and (ii) present such Existing Notes for transfer on the books of the
Company and receive all benefits and otherwise exercise all rights of beneficial
ownership of such Existing Notes, all in accordance with the terms and subject
to the conditions of the Exchange Offer.  The power of attorney granted in this
paragraph shall be deemed irrevocable and coupled with an interest.

    The undersigned hereby represents and warrants that the undersigned has full
power and authority to tender, sell, assign and transfer the Existing Notes
tendered hereby and that the Company will acquire good and unencumbered title
thereto, free and clear of all liens, restrictions, charges and encumbrances and
not subject to any adverse claim, when the same are acquired by the Company.
The undersigned hereby further represents that any Exchange Notes acquired in
exchange for Existing Notes tendered hereby will have been acquired in the
ordinary course of business of the Holder receiving such Exchange Notes, whether
or not such person is the Holder, that neither the Holder nor any such other
person has any arrangement or understanding with any person to participate in
the distribution of such Exchange Notes and that neither the Holder nor any such
other person is an "affiliate," as defined in Rule 405 under the Securities Act,
of the Company or any of its subsidiaries.

    The undersigned also acknowledges that this Exchange Offer is being made in
reliance on an interpretation by the staff of the Securities and Exchange
Commission (the "SEC") that the Exchange Notes issued in exchange for the
Existing Notes pursuant to the Exchange Offer may be offered for resale, resold
and otherwise transferred by holders thereof (other than any such holder that is
an "affiliate" of the Company 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 holders' business and such holders have
no arrangements or understandings with any person to participate in the
distribution of such Exchange Notes.  If the undersigned is not a broker-dealer,
the undersigned represents that it is not engaged in, and does not intend to
engage in, a distribution of Exchange Notes.  If the undersigned is a broker-
dealer that will receive Exchange Notes for its own account in exchange for
Existing Notes that were acquired as a result of market-making activities or
other trading activities, it acknowledges that it will deliver a


prospectus in connection with any resale of such Exchange Notes; however, by so
acknowledging and by delivering a prospectus, the undersigned will not be deemed
to admit that it is an "underwriter" within the meaning of the Securities Act.

  The undersigned will, upon request, execute and deliver any additional
documents deemed by the Exchange Agent or the Company to be necessary or
desirable to complete the assignment, transfer and purchase of the Existing
Notes tendered hereby. All authority conferred or agreed to be conferred by this
Letter of Transmittal shall survive the death, incapacity or dissolution of the
undersigned and every obligation of the undersigned under this Letter of
Transmittal shall be binding upon the undersigned's heirs, personal
representatives, successors and assigns, trustees in bankruptcy or other legal
representatives of the undersigned.  This tender may be withdrawn only in
accordance with the procedures set forth in "The Exchange Offer -- Withdrawal
Rights" section of the Prospectus.

  For purposes of the Exchange Offer, the Company shall be deemed to have
accepted validly tendered Existing Notes when, as and if the Company has given
oral or written notice thereof to the Exchange Agent.

  If any tendered Existing Notes are not accepted for exchange pursuant to the
Exchange Offer for any reason, certificates for any such unaccepted Existing
Notes will be returned (except as noted below with respect to tenders through
DTC), without expense, to the undersigned at the address shown below or at such
different address as may be indicated under "Special Delivery Instructions" as
promptly as practicable after the Expiration Date.

  The undersigned understands that tenders of Existing Notes pursuant to the
procedures described under the caption "The Exchange Offer -- Procedures for
Tendering Existing Notes" in the Prospectus and in the instructions hereto will
constitute a binding agreement between the undersigned and the Company upon the
terms and subject to the conditions of the Exchange Offer.

  Unless otherwise indicated under "Special Issuance Instructions," please issue
the certificates representing the Exchange Notes issued in exchange for the
Existing Notes accepted for exchange and return any Existing Notes not tendered
or not accepted for exchange in the name(s) of the undersigned (or in either
such event in the case of the Existing Notes tendered through DTC, by credit to
the undersigned's account at DTC). Similarly, unless otherwise indicated under
"Special Delivery Instructions," please send the certificates representing the
Exchange Notes issued in exchange for the Existing Notes accepted for exchange
and any certificates for Existing Notes not tendered or not accepted for
exchange (and accompanying documents, as appropriate) to the undersigned at the
address shown below the undersigned's signature(s), unless, in either event,
tender is being made through DTC.  In the event that both "Special Issuance
Instructions" and "Special Delivery Instructions" are completed, please issue
the certificates representing the Exchange Notes issued in exchange for the
Existing Notes accepted for exchange and return any Existing Notes not tendered
or not accepted for exchange in the name(s) of, and send said certificates to,
the person(s) so indicated.  The undersigned recognizes that the Company has no
obligation pursuant to the "Special Issuance Instructions" and "Special Delivery
Instructions" to transfer any Existing Notes from the name of the registered
Holder(s) thereof if the Company does not accept for exchange any of the
Existing Notes so tendered.

  Holders of Existing Notes who wish to tender their Existing Notes and (i)
whose Existing Notes are not immediately available or (ii) who cannot deliver
their Existing Notes, this Letter of Transmittal or any other documents required
hereby to the Exchange Agent, or cannot complete the procedure for book-entry
transfer, prior to the Expiration Date, may tender their Existing Notes
according to the guaranteed delivery procedures set forth in the Prospectus
under the caption "The Exchange Offer -- Guaranteed Delivery Procedures."  See
Instruction 1 regarding the completion of the Letter of Transmittal printed

Delivery Procedures.  This Letter of Transmittal is to be completed by Holders,
either if certificates are to be forwarded herewith or if tenders are to be made

at one of the addresses set forth herein on or prior to the Expiration Date, or
the tendering Holder must comply with the guaranteed delivery procedures set
forth below.  Existing Notes tendered hereby must be in denominations of
principal amount of $1,000 and any integral multiple thereof.

  Holders whose certificates for Existing Notes are not immediately available or
who cannot deliver their certificates and all other required documents 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 Existing
Notes pursuant to the guaranteed delivery procedures set forth in "The Exchange

Exchange Agent must receive from such Eligible Institution a properly completed
and duly executed Letter of Transmittal (or facsimile thereof) and Notice of
Guaranteed Delivery (by facsimile transmission, mail or hand delivery),
substantially in the form provided by the Company, setting forth the name and

  THE METHOD OF DELIVERY OF THIS LETTER OF TRANSMITTAL, THE EXISTING NOTES
AND ALL OTHER REQUIRED DOCUMENTS IS AT THE ELECTION AND RISK OF THE TENDERING
HOLDERS, BUT THE DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED OR
CONFIRMED BY THE EXCHANGE AGENT. IF EXISTING NOTES ARE SENT BY MAIL, IT IS

DATE TO PERMIT THE DELIVERY TO THE EXCHANGE AGENT PRIOR TO 5:00 P.M., NEW YORK
CITY TIME, ON THE EXPIRATION DATE.

  See "The Exchange Offer" section in the Prospectus.

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


  3.  Partial Tenders.  Tenders of Existing Notes will be accepted only in
integral multiples of $1,000.  If less than the entire principal amount of any
Existing Notes is tendered, the tendering Holder should fill in the principal
amount tendered in the fourth column of the box entitled "Description of 8 1/8%
Senior Notes due 2008 (Existing Notes)" above.  The entire principal amount of
Existing Notes delivered to the Exchange Agent will be deemed to have been

Holder's Existing Notes is not tendered, then Existing Notes for the principal
amount of Existing Notes not tendered and a certificate or certificates
representing Exchange Notes issued in exchange for any Existing Notes accepted
for exchange will be sent to the Holder at his or her registered address (unless
a different address is provided in the appropriate box on this Letter of
Transmittal) promptly after the Existing Notes are accepted for exchange.

  4.  Signatures on this Letter of Transmittal; Endorsements and Powers of
Attorney; Guarantee of Signatures.  If this Letter of Transmittal is signed by
the registered Holder of the Existing Notes tendered hereby, the signature must
correspond exactly with the name as written on the face of the certificates
without any change whatsoever.

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

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

  When this Letter of Transmittal is signed by the registered Holder(s) of the
Existing Notes specified herein and tendered hereby, no endorsements of
certificates or separate bond powers are required.  If, however, the Exchange
Notes are to be issued, or any Existing Notes not tendered or not accepted for
exchange are to be reissued, to a person or persons other than the registered
Holder(s), then endorsements of any certificate(s) transmitted hereby or
separate bond powers are required. Signatures on such certificate(s) or power(s)
must be guaranteed by an Eligible Institution.

  If this Letter of Transmittal is signed by a person other than the registered
Holder(s) of any certificate(s) specified herein, such certificate(s) must be
endorsed or accompanied by appropriate bond powers or powers of attorney, in
each case signed exactly as the name or names on the registered Holder(s)
appear(s) on the certificate(s) and signatures on such certificate(s) or
power(s) must be guaranteed by an Eligible Institution.

  If this Letter of Transmittal or any certificates, bond powers or powers of
attorney 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 the Company, proper evidence satisfactory to the Company of
their authority to so act must be submitted.

  Endorsements on certificates for Existing Notes or signatures on bond powers
or powers of attorney required by this Instruction 4 must be guaranteed by a
firm which is a participant in a recognized signature guarantee medallion
program (an "Eligible Institution").

  Signatures on this Letter of Transmittal must be guaranteed by an Eligible
Institution unless the Existing Notes are tendered (i) by a registered Holder of
Existing Notes (which term, for purposes of the Exchange Offer, includes any DTC
participant whose name appears on a security position listing as the Holder of
such Existing Notes) who has not completed the box entitled "Special Issuance
Instructions" or "Special Delivery Instructions" on this Letter of Transmittal,
or (ii) for the account of an Eligible Institution.

  5.  Special Issuance and Delivery Instructions.  Tendering Holders should
indicate, in the applicable box or boxes, the name and address to which Exchange
Notes or substitute Existing Notes not tendered or not


accepted for exchange are to be issued or sent, if different from the name and
address of the person signing this Letter of Transmittal (or in the case of a
tender of Existing Notes through DTC, if different from DTC). In the case of
issuance in a different name, the taxpayer identification or social security
number of the person named must also be indicated. Holders tendering Existing
Notes by book-entry transfer may request that Exchange Notes issued in exchange
for Existing Notes accepted for exchange or Existing Notes not tendered or
accepted for exchange be credited to such account maintained at DTC as such
Holder may designate hereon. If no such instructions are given, such Exchange
Notes or Existing Notes not exchanged will be returned to the name and address
of the person signing this Letter of Transmittal.

  6.  Tax Identification Number. Federal income tax law requires that a Holder
whose Existing Notes are accepted for exchange must provide the Company (as
payer) with his, her or its correct Taxpayer Identification Number ("TIN"),
which, in the case of an exchanging Holder who is an individual, is his or her
social security number. If the Company is not provided with the correct TIN or
an adequate basis for exemption, such Holder may be subject to a $50 penalty
imposed by the Internal Revenue Service (the "IRS"), and payments made with
respect to the Exchange Notes or Exchange Offer may be subject to backup
withholding at a 31% rate. If withholding results in an overpayment of taxes, a
refund may be obtained. Exempt Holders (including, among others, all
corporations and certain foreign individuals) are not subject to these backup
withholding and reporting requirements. See the enclosed "Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9."

  To prevent backup withholding, each exchanging Holder must provide his, her or
its correct TIN by completing the Substitute Form W-9 included below 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
because (i) the Holder has not been notified by the IRS that he, she or it is
subject to backup withholding as a result of a failure to report all interest or
dividends, or (ii) the IRS has notified the Holder that he, she or it is no
longer subject to backup withholding. In order to satisfy the Company that a
foreign individual qualifies as an exempt recipient, such Holder must submit a
statement signed under penalty of perjury attesting to such exempt status. Such
statements may be obtained from the Exchange Agent.  If the Existing Notes are
in more than one name or are not in the name of the actual owner, consult the
substitute Form W-9 for information on which TIN to report.  If you do not
provide your TIN to the Company within 60 days, backup withholding may begin and
continue until you furnish your TIN to the Company.

  7.  Transfer Taxes.  The Company will pay all transfer taxes, if any,
applicable to the exchange of Existing Notes pursuant to the Exchange Offer. If,
however, certificates representing Exchange Notes or Existing Notes not tendered
or accepted for exchange are to be delivered to, or are to be registered or
issued in the name of, any person(s) other than the registered Holder(s) of the
Existing Notes tendered hereby, or if tendered Existing 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 exchange of
Existing Notes pursuant to the Exchange Offer, then the amount of any such
transfer taxes (whether imposed on the registered Holder(s) or on any other
person(s)) will be payable by the tendering Holder(s). 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(s).

  Except as provided in this Instruction 7, it will not be necessary for
transfer tax stamps to be affixed to the Existing Notes listed in this Letter of
Transmittal.

  8.  Waiver of Conditions. The Company reserves the absolute right to amend,
waive or modify conditions to the Exchange Offer in the case of any Existing
Notes tendered (and to refuse to do so).


  9.  No Conditional Transfers.  No alternative, conditional, irregular or
contingent tenders will be accepted. All tendering Holders of Existing Notes, by
execution of this Letter of Transmittal, shall waive any right to receive notice
of the acceptance of their Existing Notes for exchange.

  Neither the Company, the Exchange Agent nor any other person is obligated to
give notice of any defect or irregularity with respect to any tender of Existing
Notes, nor shall any of them incur any liability for failure to give any such
notice.

  10. Mutilated, Lost, Stolen or Destroyed Existing Notes. Any tendering Holder
whose Existing Notes have been mutilated, lost, stolen or destroyed should
contact the Exchange Agent at one of the addresses indicated herein for further
instructions.

  11. Requests for Assistance or Additional Copies. Questions and requests for
assistance or additional copies of the Prospectus, this Letter of Transmittal,
the Notice of Guaranteed Delivery or the "Guidelines for Certification of
Taxpayer Identification Number" on Substitute Form W-9 may be directed to the
Exchange Agent at one of the addresses specified in the Prospectus.
