Gentlemen:

     Reference is made to that certain General Shareholders Agreement (the
"Agreement") dated September 30, 1994 among Schein Pharmaceutical, Inc.

other shareholders listed as such on Schedule A to the Agreement, and Martin

     1. You have advised Bayer that the Company proposes to refinance (the
"Refinancing") a portion of its indebtedness substantially in accordance with
the attached Senior Subordinated Credit Facility Term Sheet.

     2. You have also requested that the references in the attached letter dated
June 14, 1995 between Bayer and the Company (the "Letters) to "1996" and "1997,"
be changed to "1997" and "l998", respectively.

     3. You have further requested that "stockholders equity" as determined
under the Agreement be deemed to include the amount of any charge by the Company
for acquired in process research and development expenses of the Company

     On the terms and subject to the fulfillment of the conditions set forth
below, and for the purposes of Section 2.3 of the Agreement, Bayer hereby
consents to the Refinancing (including the Conversion Notes thereunder) so that
upon and after such Refinancing the ratio of the sum of all Funded Debt plus the

discretion) or otherwise terminated, then the applicable Ratio shall thereafter

           $100,000,000 Senior Subordinated Loan and Conversion Notes

                                SUMMARY OF TERMS


Issuer of Notes:              Schein Pharmaceutical, Inc. (the "Company" or the
                              "Issuer").

Lender and Conversion Notes
Underwriter:                  Societe Generale or Societe Generale Securities
                              Corporation ("SocGen"), as determined by Societe
                              Generale.

Structure:                    Structured as a single facility with two parts,
                              the Initial Loan and its subsequent conversion
                              (the "Conversion") into the Conversion Notes under
                              certain circumstances as described in more detail
                              below. The Company expects that prior to the
                              issuance of the Conversion Notes, the Initial Loan
                              will be refinanced by any or all of the following:
                              bank debt, a public offering or private placement
                              of high yield senior subordinated or subordinated
                              securities or an initial public or private
                              offering of common equity of the Company or one of
                              its subsidiaries (the "Refinancing"). The Initial
                              Loan will convert to the Conversion Notes if such
                              Refinancing is not consummated and the Initial
                              Loan is outstanding as of January 31, 1998 (the
                              "Maturity Date") pursuant to the terms set forth
                              below.

                                  Initial Loan

Title of Initial Loan:        Senior Subordinated Loan.

Principal Amount:             $100,000,000 aggregate principal amount.

Closing:                      Closing of the Initial Loan (the "Closing Date")
                              is expected to occur on or before December 20,
                              1996.

Maturity:                     The Initial Loan will mature on January 31, 1998
                              unless the Conversion has occurred. If the
                              Conversion occurs, the Initial Loan will be
                              converted to the Conversion Notes described below
                              on such date, provided that (i) there shall be no
                              default under the Initial Loan or any senior
                              indebtedness of the Issuer; (ii) all fees and
                              interest payable in connection with the Initial
                              Loan shall have been paid in full; and (iii) no
                              order shall be in effect enjoining the issuance of
                              the Conversion Notes.

Ranking:                      Senior subordinated, pursuant to subordination
                              provisions customary for high yield securities and
                              acceptable to SocGen. The Initial Loan will be
                              junior only to (i) the Company's existing senior
                              indebtedness as of the Closing Date and any
                              indebtedness which refinances such senior
                              indebtedness on substantially similar terms (the
                              "Senior Debt") and (ii) a basket of other senior
                              indebtedness in form, amount and terms
                              satisfactory to SocGen in all respects, and any
                              other future indebtedness will be junior to the
                              Initial Loan.

                                       1

 
                              It is understood and agreed that the obligations
                              in respect of the Initial Loan and the Conversion
                              Notes, as the case may be, will be and remain
                              obligations of the same corporate entity as the
                              Senior Debt and that the Initial Loan and the
                              Conversion Notes will have the benefit of
                              subordinated guarantees from each entity
                              guaranteeing senior debt.

                              points.

                              Interest on any overdue interest and principal
                              payments and on other amounts overdue on the
                              Initial Loan shall accrue at a rate of 200 basis
                              points in excess of the applicable rate determined
                              as provided above.

                              All interest shall be computed on the basis of a

                              paid at Closing and the other 0.5% shall be paid
                              at the earlier of (i) the repayment of the Initial
                              Loan and (ii) the Maturity Date.

                              the entire $100,000,000 principal amount of the
                              Initial Loan.

Mandatory Redemption:         Subject to the requirements of the Senior Debt
                              (including, without limitation, certain carveouts
                              to be agreed upon with respect to asset
                              sales and permitted investments), the Company
                              must repay the Initial Loan at 100% of principal
                              amount redeemed plus accrued interest to the
                              redemption date with proceeds from the Refinancing

                              upon.

                              Principal amounts repaid under this mandatory
                              redemption provision may not be drawn down again.

                              equal 103.5% of the principal amount of the
                              Initial Loan for which they are converted.

                              Interest on any overdue interest and principal

      General Terms Applicable to the Initial Loan and the Conversion Notes


Optional Prepayment:          The Initial Loan may be prepaid at the option of
                              the Company in whole or in part up to an aggregate
                              principal amount equal to $25 million plus accrued
                              interest to the prepayment date (see above).

                              Partial prepayments will be allowed only in whole
                              dollar amounts of at least $1,000,000 of principal
                              up to $25 million.

                              Principal amounts prepaid may not be drawn down
                              again.

                              The Conversion Notes will be non-callable for the
                              life of the issue.

Transferability:              The Initial Loan and the Conversion Notes shall be
                              transferable, without restriction, by the
                              lender(s) or holder(s) thereof. See "Registration
                              Rights".

                              Issuer will then use its best efforts to cause to
                              become effective such registration statement for
                              the Conversion Notes as soon as practicable after

                              the Conversion Note indenture (which terms
                              includes any agreement, security documents or
                              other documents as SocGen may determine to be

                              contemplated hereby) will contain representations

                              the Initial Loan as soon as practicable pursuant
                              to a securities offering or otherwise.

Covenants:                    The Agreement (and, if executed, the indenture for
                              the Conversion Notes) will contain affirmative and
                              negative covenants satisfactory to SocGen,

                              determined to be appropriate by SocGen) shall be
                              governed by and construed in accordance with the
                              laws of the State of New York, without giving

                                   Underwriting

Advisory Fee:                 The Company shall pay to SocGen an advisory fee
                              equal to 1.5% of the principal amount of the
                              Initial Loan upon the occurrence of a Refinancing.

Underwriting Commission:      In the event the Company selects SocGen to
                              participate as an underwriter in a Refinancing, 
                              SocGen's underwriting commission (to be
                              determined at the time of Refinancing) shall be
                              reduced by an amount equal to the lesser of (i)

                              such Refinancing and (ii) the Advisory Fee. In the
                              event such underwriting commission exceeds
                              $1,500,000, the Company selects SocGen to act as
                              lead manager of such an underwriting, and SocGen
                              earns at least 70% of the total commissions paid
                              for such underwriting, and SocGen shall reimburse
                              the Company for expenses incurred by the Company
                              in connection with the Refinancing in an amount
                              equal to the lesser of (i) SocGen's total
                              underwriting commission earned from such
                              Refinancing minus $1,500,000 and (ii) $500,000.

     incurred as part of an Acceptable Refinancing or any other Refinancing
     Debt."

     Debt (including, without limitation, maturity, interest rates,
     subordination provisions, prepayment, redemption, defeasance or similar
     provisions, covenants and events of default) shall be in all material
     respects at least as favorable to the Borrower and the Lenders as the terms
     of the Indebtedness being refinanced (or, if the Indebtedness being
     refinanced was incurred under the Senior Subordinated Loan Agreement or the
     Conversion Note Indenture, at least as favorable to the Borrower and the
     Lenders as the terms of the Indebtedness issued (or that would have been
     issued) under the Conversion Note Indenture) or, in the case of interest
     rates, shall be consistent with rates of interest at the time prevailing in
     the market for comparable obligations.

     (b) Section 6.12 is amended by deleting the text after the word
"Indebtedness" and inserting in place thereof:

     "except that the Borrower and the Subsidiaries may (i) make payments in

     of the Borrower and (iii) refinance Indebtedness incurred as part of an
     Acceptable Refinancing or Refinancing Debt with the proceeds of any
     issuance and sale of capital stock (or rights, warrants or options to
     acquire capital stock) of the Borrower or of any Refinancing Debt permitted
     under Section 6.01(g)."
