To Holders of Units of Limited Partnership Interest in PaineWebber R&D
Partners II, L.P.:

                              INTRODUCTION

     BioRoyalties, L.L.C., a Delaware limited liability company (the
"Purchaser"), on behalf of Pharmaceutical Royalties, L.L.C, a Delaware limited
liability company, and Pharmaceutical Royalty Investments Ltd., a Bermuda
company (collectively the "Funds"), hereby offer to purchase any and all
outstanding units of limited partnership interest (the "Units") in PaineWebber
R&D Partners II, L.P., a Delaware limited partnership (the "Partnership"), for
cash consideration per Unit of $3,650, upon the terms and subject to the
conditions set forth in this Offer to Purchase and the related Letter of
Transmittal (which, together with any amendments or supplements hereto or
thereto, collectively constitute the "Offer").  The Purchase Price will be
automatically reduced by the aggregate amount of any cash or asset
distributions made or declared by the Partnership on or after June 30, 1997 and
prior to either the date on which the Purchaser pays the Purchase Price for the
tendered Units in the case of a distribution of cash or, in the case of a
distribution of assets, the date assets are to be assigned to the Purchaser.
This Offer is made to all beneficial owners of Units (each a "Holder").

     The Purchaser and the Funds are making this Offer because the Funds
believe that the Units represent an attractive investment at the price offered.
There can be no assurance, however, that this belief is correct and, as a
result, ownership of Units (either by the Purchaser, the Funds or Holders who
retain their Units) remains a speculative investment.  The Funds are acquiring
the Units for investment purposes and do not currently intend to make any
effort to change the management or operations of the Partnership and have no
current plans for any extraordinary transaction regarding the Partnership.

     The Purchaser is not affiliated with the General Partner of the
Partnership.

     As of the date of this Offer, the General Partner of PaineWebber R&D
Partners II, L.P., PaineWebber Technologies II, L.P., has not made any
recommendation to any Holders as to whether to tender or refrain from tendering
Units.  Each Holder must make his or her own decision whether to tender or
refrain from tendering his or her Units.  No later than 10 business days from
the date of this Offer, the General Partner is required by law to issue a
statement that (i) the Partnership accepts or rejects the Offer, (ii) the
Partnership expresses no opinion and is remaining neutral toward the Offer or
(iii) the Partnership is unable to take a position with respect to the Offer.

     The Offer is conditioned upon, among other things, Purchaser being
satisfied, in its sole discretion, that, upon purchase of the Units pursuant to
the Offer, it, the Funds and/or their nominee will have full rights to
ownership as to all such Units and that the General Partner will consent to it,
the Funds or their nominee becoming assignees of the purchased Units and a
substitute limited partner with respect to all such Units.  The Offer is also
subject to certain other conditions contained in this Offer to Purchase.  See
Sections 2 and 14.

     According to a Quarterly Report on Form 10-Q for the quarter ended June
30, 1997 filed by the Partnership (the "Partnership 10-Q"), 8,257 Units were
issued and outstanding.

     Tendering Holders will not be obligated to pay brokerage fees or
commissions, except transfer taxes, if applicable, on the purchase of Units
pursuant to the Offer.  Purchaser will pay all charges and expenses of The
Herman Group, as the depositary (the "Depositary") and information agent (the
"Information Agent") incurred in connection with the Offer. See Section 16.

     According to the July 1987 Prospectus, the Partnership's principal
objective was to achieve substantial returns to investors over a 6-8 year
period by investing in the development and commercialization of new products
being developed by leading technology companies.  In pursuing this

                                     4
<PAGE>

strategy, the Partnership funded ten projects, of which three -- those with
Centocor, Inc., Genzyme Corporation and Synergen (now Amgen Boulder), Inc. --
are ongoing.  The remaining seven projects have either terminated or are near
termination.  From inception through June 30, 1997, each Holder had received
cumulative distributions of $9,722 per $10,000 Unit, consisting of cash
distributions of $2,516 and in kind distributions (stock and warrants) valued
at $7,206 at the time of distribution.  See Section 13.

     From time to time during the past 6 months, the Purchaser has discussed
with the General Partner the possibility of purchasing for cash all of the
remaining assets of the Partnership.  On March 26, 1997, the Purchaser made an
offer to the General Partner to acquire all of the assets of the Partnership
for $23 million in cash (equivalent to $2,785 per Unit).  On June 9, 1997,
following the Partnership's agreement to settle pending litigation with
Centocor, the Purchaser made an offer to the General Partner to acquire all of
the assets of the Partnership for $29 million in cash (equivalent to $3,500 per
Unit).  The General Partner declined both offers.  As a result of its inability
to negotiate the purchase of all of the assets of the Partnership, the
Purchaser has made the Offer directly to each Holder in order that such Holder
can decide whether to tender his or her Units at the Purchase Price.

A Holder may wish to tender Units for a number of reasons:

- -    LIQUIDITY OPPORTUNITY.  The Offer provides each Holder the opportunity
     to liquidate his or her investment in the Partnership without transfer
     fees and transaction costs generally incurred in secondary market sales
     (which can range from 5% to 8.75% of the sale price).  Although there are
     limited resale mechanisms available to Holders through partnership
     matching services, there is no formal trading market for the Units.
     According to the Partnership's Annual Report on Form 10-K for the fiscal
     year ended December 31, 1996 (the "Partnership 10-K") "there is no
     established trading market for the limited partnership interests, and no
     such market is expected to develop."

- -    PURCHASE PRICE GREATER THAN GENERAL PARTNER'S JULY 1996 VALUATION FOR
     ERISA PURPOSES.  The aggregate Purchase Price is greater than the $29
     million valuation of the Partnership prepared by the General Partner in
     July 1996 for ERISA purposes.  In addition, since the date of the General
     Partner's valuation, the Partnership has distributed approximately $7.7
     million in cash.

- -    PREMIUM TO HISTORICAL PRICES.  The Purchase Price represents a premium of
     46% to the most recent and highest selling price ($2,500 per Unit) of a
     Unit traded on the Chicago Partnership Board or in any other transaction
     of which Purchaser is aware.

- -    POTENTIAL TAX BENEFIT, ENHANCED BY CHANGE IN CAPITAL GAIN RATES TO 20%.
     Each holder is generally taxable on his or her allocable share of
     Partnership profits, a portion of which are ordinary income.  Ordinary
     income is taxed to individuals at rates of up to 39.6%.  A portion of the
     gain resulting from the sale of a Unit should be taxed to non-corporate
     Holders at capital gain rates (currently 20% for most individuals
     disposing of capital assets held more than 18 months), possibly resulting
     in tax savings.  In addition, the sale of a Unit may enable a Holder to
     use previously disallowed passive loss carryforwards, accelerating their
     recognition.  THE PURCHASER IS NOT EXPRESSING AN OPINION AS TO THE TAX
     CONSEQUENCES OF TENDERING UNITS.  Holders are strongly advised to consult
     their tax advisors with respect to the tax consequences of accepting the
     Offer.

- -    RESOLUTION OF LITIGATION.  On June 6, 1997, Centocor and the Partnership
     reached an agreement to settle a dispute over payments owed to investors
     in Centocor Partners III, L.P.  The settlement is subject to court
     approval, for which a hearing is scheduled on September 4, 1997.  If
     approved, the agreement would result in one-time cash payments per Unit
     of approximately $420 in 1997, $280 in 1998, and $95 if and when ReoPro
     is approved for marketing in Japan. The Partnership is also entitled to
     receive payments based on the sales of ReoPro over the next 10 years,
     which have been revised under the settlement agreement.  The Purchaser
     has considered the value of these payments in determining the Purchase
     Price.

                                     5
<PAGE>

- -    SIMPLIFIED TAX RETURNS.  The Offer may be attractive to certain Holders
     who wish in the future to avoid the expenses, delays and complications of
     filing complex income tax returns resulting from Form K-1s necessitated
     by ownership of  Units.

- -    VALUE DEPENDENT ON ONE PRODUCT.  The Purchaser believes that a
     substantial portion of the value of the Partnership is attributable to
     the right to receive cash payments based on the future sales of ReoPro.
     There are at least four other products having a mechanism of action
     similar to that of ReoPro that are in clinical development for the same
     or similar indications.  There can be no assurance that the sales of
     ReoPro will not be adversely affected by these products.

- -    POSSIBLE REGULATORY ISSUES.  The Partnership's Centocor CPRs may be
     considered securities under the Investment Company Act of 1940 (the
     "Act").  As a result, the Partnership will need to determine whether it
     is subject to the Act and possible implications for its future business
     strategy.  One possible way to avoid issues that might arise under the
     Act is to distribute the CPRs. In a partnership with similar investments,
     PaineWebber R&D Partners, L.P., the partnership distributed to its
     limited partners securities similar to the CPRs. If the General Partner
     were to distribute to each Holder his or her PRO RATA share of CPRs,
     each Holder would receive an asset for which there is not likely to be a
     market, and for which the value depends exclusively on the sales of a
     single pharmaceutical product over a 10 year period.  The Purchaser
     believes that if this strategy were pursued it would negatively impact
     the ability of a Holder to maximize the value of his or her interest.

1.  TERMS OF THE OFFER

     Upon the terms and subject to the conditions of the Offer (including, if
the Offer is extended or amended, the terms and conditions of any such
extension or amendment), Purchaser will accept for payment (and thereby
purchase) any and all Units that are validly tendered and not withdrawn in
accordance with Section 4 prior to the Expiration Date.  As used in the Offer,
the term "Expiration Date" means 12:00 midnight, New York City time, on
September 12, 1997, unless and until Purchaser, in accordance with the terms of
the Offer, shall have extended the period of time during which the Offer is
open, in which event the term "Expiration Date" means the latest time and date
at which the Offer, as so extended, expires.  As used in this Offer to
Purchase, "business day" has the meaning set forth in Rule 14d-1(c)(6) under
the Securities Exchange Act of 1934, as amended (the "Exchange Act").

     The Offer is not conditioned upon any minimum number of Units being
tendered.  The Offer is subject to certain other conditions set forth in
Sections 2 and 14.  Purchaser expressly reserves the right (but will not be
obligated) to waive any or all of the conditions of the Offer.  If, by the
Expiration Date, any or all of the conditions of the Offer are not satisfied or
waived, Purchaser reserves the right (but shall not be obligated) to (i) extend
the period during which the Offer is open and, subject to the rights of
tendering Holders to withdraw their Units, retain all tendered Units until the
Expiration Date, (ii) waive any or all of the conditions of the Offer and,
subject to compliance with applicable rules and regulations of the Securities
and Exchange Commission (the "Commission"), accept for payment or purchase all
validly tendered Units and not extend the Offer, or (iii) terminate the Offer
and not accept for payment any Units and return promptly all tendered Units to
tendering Holders.  Any extension, delay in payment, termination or amendment
may be made by giving oral or written notice to the Depositary and will be
followed as promptly as practicable by public announcement, the announcement in
the case of an extension to be issued no later than 9:00 a.m., New York City
time, on the next business day after the previously scheduled Expiration Date.

     Following the expiration of the Offer or if the Offer is not consummated,
the Purchaser and the Funds may seek to acquire Units through open-market
purchases, privately negotiated transactions or otherwise, upon such terms and
conditions and at such prices as it shall determine, which may be more or less
than the Offer Price and could be for cash or other consideration.

                                     6
<PAGE>

     The Commission has announced that, under its interpretation of Rules
14d-4(c) and 14d-6(d) under the Exchange Act, material changes in the terms of
a tender offer or information concerning a tender offer may require that the
tender offer be extended so that it remains open a sufficient period of time to
allow Holders to consider such material changes or information in deciding
whether or not to tender or withdraw their securities.  The minimum period
during which an offer must remain open following material changes in the terms
of the Offer or information concerning the Offer, other than a change in price
or a change in percentage of securities sought, will depend upon the facts and
circumstances, including the relative materiality of the terms or information.
If Purchaser decides to increase or decrease the consideration in the Offer or
to make a change in the percentage of Units sought and if, at the time that
notice of any such change is first published, sent or given to Holders, the
Offer is scheduled to expire at any time earlier than the tenth business day
after (and including) the date of that notice, the Offer will be extended at
least until the expiration of that period of ten business days.

2.   PRORATION; ACCEPTANCE FOR PAYMENT AND PAYMENT

     If the number of Units validly tendered (and not properly withdrawn) on or
before the Expiration Date is greater than the number (the "Number of Valid
Units") for which Purchaser is satisfied, in its sole discretion, that it
and/or its nominee will have all of the rights of a limited partner, the
Purchaser will accept for payment (and thereby purchase) only the Number of
Valid Units.  The Purchaser will acquire the Number of Valid Units PRO RATA to
the number of Units validly tendered (and not properly withdrawn) on or before
the Expiration Date, with appropriate adjustments to avoid purchases in
fractions of other than half Units.  If the number of Units validly tendered
(and not properly withdrawn) on or before the Expiration Date is not greater
than the Number of Valid Units, Purchaser will purchase all Units validly
tendered (and not properly withdrawn) on or before the Expiration Date, upon
the terms and subject to the conditions of the Offer.

     In the event that proration is required as a result of the General
Partner's limiting transfers, Purchaser may not be able to announce the final
results of such proration until at least ten business days after the Expiration
Date.  Subject to the Purchaser's obligation under Rule 14e-1(c) under the
Exchange Act to pay Holders the Purchase Price in respect of Units tendered or
return those Units promptly after the termination or withdrawal of the Offer,
the Purchaser does not intend to pay for any Units accepted for payment
pursuant to the Offer until the final proration results are known and it has
received notice from the Partnership or its transfer agent that the Units are
eligible for transfer to the Purchaser.

     Upon the terms and subject to the conditions of the Offer (including, if
the Offer is extended or amended, the terms and conditions of any such
extension or amendment) and subject to the foregoing paragraphs, Purchaser will
accept for payment (and thereby purchase) and pay for all Units which are
validly tendered (and not properly withdrawn) prior to the Expiration Date,
promptly after the later to occur of: (i) the Expiration Date and (ii) the date
of satisfaction or waiver of all the conditions to the Offer set forth in this
Offer to Purchase.  Subject to the applicable rules of the Commission,
Purchaser expressly reserves the right to delay acceptance for payment of or
payment for Units pending receipt of any regulatory approval specified in
Section 15 or in order to comply, in whole or in part, with any other
applicable law or government regulation.  See Sections 14 and 15.

     In all cases, payment for Units purchased pursuant to the Offer will be
made only after timely receipt by the Depositary of (i) the Letter of
Transmittal (or manually signed facsimile thereof), properly completed and duly
executed with a Medallion signature guarantee and (ii) confirmation to
Purchaser of such Holder's ownership by MMS Escrow and Transfer Agency, Inc.,
the registrar and transfer agent of the Units.

                                     7
<PAGE>

     For purposes of the Offer, Purchaser will be deemed to have accepted for
payment and thereby purchased Units validly tendered and not properly withdrawn
if and when Purchaser gives oral or written notice to the Depositary of
Purchaser's acceptance of such Units for payment.  Payment for Units accepted
pursuant to the Offer will be made by deposit of the Purchase Price with the
Depositary, which will act as agent for tendering Holders for the purpose of
receiving payment from Purchaser and transmitting payment to tendering Holders.
Upon the deposit of funds with the Depositary for the purpose of making
payments to tendering Holders, Purchaser's obligation to make such payment
shall be satisfied and tendering Holders must thereafter look solely to the
Depositary for payment of amounts owed to them by reason of the acceptance for
payment of Units pursuant to the Offer.  Purchaser will pay any transfer taxes
incident to the transfer to it of validly tendered Units, as well as any
charges and expenses of the Depositary and the Information Agent.  Under no
circumstances will interest accrue on the consideration to be paid for the
Units by Purchaser, regardless of any delay in making such payment.

     If, prior to the Expiration Date, Purchaser increases the consideration to
be paid per Unit pursuant to the Offer, Purchaser will pay the increased
consideration for all the Units purchased pursuant to the Offer, whether or not
the Units were tendered prior to the increase in consideration.  Purchaser does
not currently expect to increase the consideration to be paid per Unit pursuant
to the Offer.

     Purchaser reserves the right to transfer or assign, in whole at any time,
or in part from time to time, to one or more of its affiliates, the right to
purchase all or any portion of the Units tendered pursuant to the Offer,
provided that any such transfer or assignment will not relieve Purchaser of its
obligations under the Offer and will in no way prejudice the rights of
tendering Holders to receive payment for Units validly tendered and accepted
for payment pursuant to the Offer.

3.  PROCEDURE FOR TENDERING UNITS

     VALID TENDERS.  For Units to be validly tendered pursuant to the Offer, a
Letter of Transmittal (or a manually signed facsimile), properly completed and
duly executed, with a Medallion signature guarantee and any other documents
required by the Letter of Transmittal, must be received by the Depositary at
its address set forth on the back cover of this Offer to Purchase prior to the
Expiration Date.

     SIGNATURE GUARANTEES.  In all cases, signatures on the Letter of
Transmittal must be guaranteed by a participant in the Security Transfer Agents
Medallion Program, the New York Stock Exchange Medallion Signature Guarantee
Program or the Stock Exchange Medallion Program (an "Eligible Institution").
SEE INSTRUCTION 2 OF THE LETTER OF TRANSMITTAL.  If the Units are registered in
the name of a person other than the signer of the Letter of Transmittal, or if
payment is to be made to a person other than the registered Holder of the Units
surrendered, then the Letter of Transmittal for the tendered Units must be
endorsed or accompanied by appropriate stock powers, in each case signed
exactly as the name or names of the registered Holder appears in the records of
MMS Escrow and Transfer Agency, Inc.  SEE INSTRUCTIONS 1 AND 2 OF THE LETTER OF
TRANSMITTAL.

     IN ALL CASES, UNITS SHALL NOT BE DEEMED VALIDLY TENDERED UNLESS A PROPERLY
COMPLETED AND DULY EXECUTED LETTER OF TRANSMITTAL (OR A MANUALLY SIGNED
FACSIMILE) IS RECEIVED BY THE DEPOSITARY.

     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ANY OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER.  IF DELIVERY IS
MADE BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS RECOMMENDED.  IN
ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.

     Notwithstanding any other provision of this Offer to Purchase, payment for
Units accepted for payment pursuant to the Offer in all cases will be made only
after timely receipt by the Depositary of confirmation of such Holder's
ownership by MMS Escrow and Transfer Agency, Inc., the registrar and

                                     8
<PAGE>

transfer agent for the Units, and a Letter of Transmittal (or a manually
signed facsimile), properly completed and duly executed, with a Medallion
signature guarantees, and all other documents required by the Letter of
Transmittal.

     DETERMINATION OF VALIDITY.  All questions as to the form of documents and
the validity, eligibility (including time of receipt) and acceptance for
payment of any tender of Units pursuant to any of the procedures described
above will be determined by Purchaser in its sole discretion, which
determination shall be final and binding on all parties.  Purchaser reserves
the absolute right to reject any or all tenders of Units determined not to be
in proper form or the acceptance of or payment for which may, in the opinion of
counsel, be unlawful and reserves the absolute right to waive any defect or
irregularity in any tender of Units.  Purchaser also reserves the absolute
right to waive or amend any or all of the conditions of the Offer.  Purchaser's
interpretation of the terms and conditions of the Offer (including the Letter
of Transmittal and its instructions) will be final and binding on all parties.
No tender of Units will be deemed to have been validly made, until all defects
and irregularities have been cured or waived.  None of Purchaser, the
Depositary, the Information Agent or any other person will be under any duty to
give notification of any defects or irregularities in tenders or incur any
liability for failure to give any such notification.

     APPOINTMENT as PROXY.  By executing and delivering the Letter of
Transmittal, a tendering Holder irrevocably appoints designees of Purchaser as
his or her attorneys-in-fact and proxies, with full power of substitution, in
the manner set forth in the Letter of Transmittal, to the full extent of the
Holder's rights with respect to the Units (and with respect to any and all
other securities issued or issuable in respect of such Units on or after the
date hereof) tendered by the Holder.  All such powers of attorney and proxies
will be considered coupled with an interest in the tendered Units and all prior
powers of attorney and proxies given by the Holder with respect to the Units
will be revoked, without further action, and no subsequent powers of attorney
and proxies may be given (and, if given, will not be deemed effective) by the
Holder.  Designees of Purchaser will be empowered to exercise all voting and
other rights of the Holder with respect to such Units as they in their sole
discretion may deem proper, including, without limitation, in respect of any
annual or special meeting of the Holders, or any adjournment or postponement of
any such meeting, or in connection with any action by written consent in lieu
of any such meeting or otherwise.  Purchaser reserves the absolute right to
require that, in order for Units to be validly tendered, immediately upon
Purchaser's acceptance for payment of the Units, Purchaser must be able to
exercise full voting and other rights with respect to the Units.

     A tender of Units pursuant to any of the procedures described above will
constitute the tendering Holder's acceptance of the terms and conditions of the
Offer.  Purchaser's acceptance for payment of Units tendered pursuant to the
Offer will constitute a binding agreement between the tendering Holder and
Purchaser upon the terms and conditions of the Offer.

4.  WITHDRAWAL RIGHTS

     Tenders of Units made pursuant to the Offer are irrevocable, except as
otherwise provided in this Section 4.  Units tendered pursuant to the Offer may
be withdrawn at any time prior to the Expiration Date and, unless theretofore
accepted for payment by Purchaser as provided in this Offer to Purchase, may
also be withdrawn at any time after October 14, 1997.  If Purchaser extends the
Offer, is delayed in its purchase of or payment for Units, or is unable to
purchase or pay for Units for any reason then, without prejudice to the rights
of Purchaser, tendered Units may be retained by the Depositary on behalf of
Purchaser and may not be withdrawn, except to the extent that tendering Holders
are entitled to withdrawal rights as set forth in this Section 4.

     The reservation by Purchaser of the right to delay the acceptance or
purchase of or payment for Units is subject to the provisions of Rule 14e-1(c)
under the Exchange Act, which requires Purchaser to

                                     9
<PAGE>

pay the consideration offered or to return Units deposited by or on behalf of
Holders promptly after the termination or withdrawal of the Offer.

     For a withdrawal to be effective, a written, telegraphic or facsimile
transmission notice of withdrawal must be timely received by the Depositary at
it address set forth on the back cover of this Offer to Purchase.  Any such
notice of withdrawal must specify the name of the persons who tendered the
Units to be withdrawn, the number of Units to be withdrawn and the name of the
registered Holder, if different from that of the person who tendered the Units.
All questions as to the form and validity (including time of receipt) of
notices of withdrawal will be determined by Purchaser, in its sole discretion,
whose determination will be final and binding on all parties.  No withdrawal of
Units will be deemed to have been made properly until all defects and
irregularities have been cured or waived.  None of Purchaser, the Depositary,
the Information Agent or any other person will be under any duty to give
notification of any defects or irregularities in any notice of withdrawal or
incur any liability for failing to give such notification.

     Any Units properly withdrawn will be deemed not validly tendered for
purposes of the Offer, but may be tendered at any subsequent time prior to the
Expiration Date by following any of the procedures described in Section 3
above.

5.  CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE OFFER

      The following is a general discussion of certain federal income tax
consequences of a sale of Units pursuant to the Offer, assuming that the
Partnership is treated and taxable as a partnership for federal income tax
purposes.  This summary is of a general nature only and does not discuss all
aspects of federal income taxation that may be relevant to each Holder in light
of such Holder's particular circumstances.  In addition, the summary does not
discuss aspects of federal income taxation that may be relevant to Holders
subject to special treatment under the federal income tax laws, such as foreign
persons, dealers in securities, insurance companies, tax-exempt organizations,
banks, thrifts, regulated investment companies or Holders that do not hold
Units as capital assets (within the meaning of Section 1221 of the Internal
Revenue Code of 1986, as amended (the "Code")).  This summary is based on the
Code, Treasury regulations thereunder, and administrative and judicial
interpretations thereof, as of the date hereof, all of which are subject to
change, possibly on a retroactive basis.

EACH HOLDER SHOULD CONSULT HIS OR HER OWN TAX ADVISOR AS TO THE PARTICULAR TAX
CONSEQUENCES TO SUCH HOLDER OF SELLING UNITS PURSUANT TO THIS OFFER.  THIS
SUMMARY DOES NOT DISCUSS ANY FOREIGN, STATE OR LOCAL TAX CONSEQUENCES OF
SELLING UNITS PURSUANT TO THIS OFFER.

     CONSEQUENCES TO HOLDERS WHO TENDER UNITS.  A Holder who tenders Units
pursuant to the Offer generally will recognize gain or loss equal to the
difference between (i) the Holder's "amount realized" and (ii) the Holder's
adjusted tax basis in the Units tendered.  The amount realized with respect to
a Unit sold pursuant to the Offer is the sum of the amount of cash received by
the Holder for such Unit and such Holder's share of Partnership liabilities
allocable to such Unit (as determined under Section 752 of the Code).  The
amount of a Holder's adjusted tax basis in his or her Units will vary depending
on the Holder's particular circumstances, and will be affected by both
allocations of Partnership income, gain and loss during the year in which Units
are tendered, and distributions, if any, made by the Partnership to a Holder
with respect to such Units during such year.  The Partnership's taxable income,
gain and loss for the taxable year will be allocated between the Purchaser and
tendering Holders in accordance with the terms of the Partnership Agreement.

     TAX BASIS IN UNITS.  The IRS has ruled that a partner has one basis for
the partner's entire interest in a partnership even if a partner bought
partnership interests in different transactions.  Upon a sale of a

                                     10
<PAGE>

portion of such aggregate interest (e.g., in a partial tender of Units), a
Holder would be required to allocate such Holder's aggregate tax basis between
the Units sold and the Units retained using some equitable apportionment
method, such as the relative fair market value of such Units on the date of
sale.  It is not entirely clear whether the aggregation rule results in the
tacking of the holding period of earlier purchased Units to more recently
acquired Units.

     CHARACTERIZATION OF GAIN OR LOSS.  Gain or loss recognized by a Holder on
the sale of Units pursuant to the Offer generally will be capital gain or loss.
However, under Section 751 of the Code, the difference between the portion of
the amount realized by a Holder that is attributable to "unrealized
receivables" and "inventory" (together, "Section 751 Property") over the
portion of the Holder's adjusted tax basis in the Unit that is allocated to
Section 751 Property will be treated as ordinary income or loss, rather than
capital gain or loss.  In certain cases, ordinary income recognized under
Section 751 of the Code may exceed net taxable gain realized on the sale of a
Unit and may be recognized even if there is a net taxable loss realized on the
sale of a Unit.  Existing Treasury regulations require each person who
transfers an interest in a partnership possessing Section 751 Property to file
a statement with such person's tax return reporting the transfer and certain
other information relating thereto.

     The Taxpayer Relief Act of 1997 (HR 2014) (the "Act"), enacted into law on
August 5, 1997, generally reduces the maximum rate of tax on net capital gain
for individuals, estates and trusts from 28% to 20% (in addition, the Act
provides for additional rate reductions on gains attributable to dispositions
of certain property for the taxable years beginning after December 31, 2000).
However, for sales or exchanges of capital assets after July 28, 1997, the 20%
rate applies only to gains attributable to such assets that were held for more
than 18 months.  The maximum rate of 20% does not apply to gain on the sale of
collectibles and to certain other gain.  The 28% rate continues to apply to
gains attributable to sales or exchanges of capital assets held for more than
one year but not more than 18 months.  For non-corporate taxpayers, capital
losses are deductible only to the extent of capital gains plus up to $3,000 of
ordinary income.  If capital losses are not used in a tax year, such losses
generally can be carried forward to succeeding tax years indefinitely.  Non-
corporate taxpayers are not entitled to carry back capital losses to prior
taxable years.

     Under current law, the maximum federal income tax rate applicable to
capital gains and ordinary income for corporations is 35%.  Corporations may
only offset capital losses against capital gains. Corporations are entitled to
carry back unused capital losses to the three preceding taxable years and carry
forward unused capital losses to the succeeding five taxable years.

     EFFECT OF PASSIVE LOSS RULES.  Under Section 469 of the Code, a non-
corporate taxpayer or personal service corporation generally can deduct passive
activity losses in any year only to the extent of such person's passive
activity income for such year, and closely held corporations may not offset
such losses against so-called "portfolio" income.  Provided that a Holder is
subject to the passive activity loss rules in connection with the ownership of
Units, a Holder with "suspended" passive activity losses generally should be
entitled to offset such losses against any income or gain recognized by the
Holder on a sale of all of such Units (subject to certain other limitations).
If a Holder does not sell all of his or her Units, the passive activity loss
limitations would continue to apply until the Holder disposes of all of his or
her remaining Units.

     BACK-UP WITHHOLDING.  A Holder (other than corporations and certain
foreign individuals) who tenders Units may be subject to 31% backup withholding
unless he or she provides a taxpayer identification number ("TIN") and
certifies that the TIN is correct or properly certifies that he or she is
awaiting a TIN.  A Holder may avoid backup withholding by properly completing
and signing the Substitute Form W-9 included as part of the Letter of
Transmittal.  IF A HOLDER WHO IS SUBJECT TO BACKUP WITHHOLDING DOES NOT
PROPERLY COMPLETE AND SIGN THE SUBSTITUTE FORM W-9, THE PURCHASER WILL WITHHOLD
31% FROM PAYMENTS TO SUCH HOLDER.  SEE INSTRUCTION 4 TO THE LETTER OF
TRANSMITTAL.

                                     11

<PAGE>

     POSSIBLE LEGISLATIVE TAX CHANGES.  There have been a number of proposals
made in Congress and by the Treasury Department and other government agencies
for changes in the federal income tax laws.  In addition, the Internal Revenue
Service has proposed and may still be considering changes in regulations and
procedures.  It is likely that further proposals will be forthcoming or that
previous proposals will be revived in some form in the future.  It is
impossible to predict with any degree of certainty what past proposals may be
revived or what new proposals may be forthcoming, the likelihood of adoption of
any such proposals, the likely effect of any such proposals upon investment in
the Partnership or upon the sale of Units, or the effective date of any
legislation which may derive from any such past or future proposals.  Holders
are strongly urged to consider ongoing developments in this uncertain area.

THE FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL
INFORMATION PURPOSES ONLY.  LIMITED PARTNERS SHOULD CONSULT THEIR OWN TAX
ADVISORS TO DETERMINE THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF
THE OFFER.

6.   PRICE RANGE OF THE UNITS

     According to the Annual Report on Form 10-K for the fiscal year ended
December 31, 1996 filed by the Partnership (the "Partnership 10-K") "there is
no existing public market for the Units, and no such market is expected to
develop."  According to Partnership Spectrum, an independent third-party
industry publication that tracks recent trades in certain limited partnership
interests, for the twelve months ended May 31, 1997, 29.5 Units traded at per
Unit prices between $580 and $2,301 with a weighted average of $1,215 per Unit.
The most recent issue of the Partnership Spectrum (May/June, 1997) indicates
that 3.0 Units traded in the period April 1, 1997 through May 31, 1997 at
between $2,200 and $2,301.38 per Unit, with a weighted average of $2,267.58 per
Unit.

     Holders are advised, however, that such gross sales prices reported by The
Partnership Spectrum do not necessarily reflect the net sales proceeds received
by sellers of Units, which typically are reduced by commissions and other
secondary market transaction costs to amounts less than the reported prices.
Also, trades may have occurred at higher or lower prices which were not
reported by the Partnership Spectrum and the Purchaser makes no representation
as to the accuracy or completeness of the trade information.  Not all trades
are reported in the Partnership Spectrum.

     The Purchase Price represents the price at which the Purchaser is willing
to purchase Units.  No independent person has been retained to evaluate or
render any opinion with respect to the fairness of the Purchase Price and no
representation is made by the Purchaser or any affiliate of the Purchaser as to
such fairness. Purchaser did not attempt to obtain current independent
valuations or appraisals of the underlying assets owned by the Partnership.
Other measures of the value of the Units may be relevant to Holders.  HOLDERS
ARE URGED TO CONSIDER CAREFULLY ALL OF THE INFORMATION CONTAINED HEREIN AND
CONSULT WITH THE 


                                      12

<PAGE>

OWN ADVISORS, TAX, FINANCIAL OR OTHERWISE, IN EVALUATING THE TERMS OF THE 
OFFER BEFORE DECIDING WHETHER TO TENDER UNITS.

7.   EFFECT OF THE OFFER ON EXCHANGE ACT REGISTRATION

     The Units are currently registered under the Exchange Act.  Such
registration may be terminated upon application of the Partnership to the
Commission if the Units are neither listed on a national securities exchange
nor held by 300 or more holders of record.  Termination of the registration of
the Units under the Exchange Act would substantially reduce the information
required to be furnished by the Partnership to Holders and to the Commission
and would make certain of the provisions of the Exchange Act no longer
applicable to the Units.  Although the Purchaser would consider causing the
Partnership to terminate registration of the Units under the Exchange Act if
the requirements for termination of registration of the Units are met, the
Purchaser currently has no plans to seek to cause the Partnership to terminate
such registration.

8.   CERTAIN INFORMATION CONCERNING THE PARTNERSHIP

     The Partnership is a Delaware limited partnership that commenced
operations on September 30, 1987 with a total of $72 million available for
investment.  PWDC Holding Company (the "Manager") is the general partner of
PaineWebber Technologies II, L.P., which is the general partner (the "General
Partner") of the Partnership.  PWDC Holding Company is a wholly owned
subsidiary of PaineWebber Development Corporation ("PWDC"), an indirect wholly-
owned subsidiary of PaineWebber Group Inc. ("PWG").  According to the
prospectus dated July 16, 1987, the General Partner was to seek to obtain
substantial returns for investors over six to eight years through the
development and commercialization of new products (the "Projects").  The
Partnership 10-Q states that the principal objective of the Partnership is to
provide long-term capital appreciation to investors through investing in the
development and commercialization of new products.  The Partnership will
terminate on December 31, 2012, unless its term is extended or reduced by the
General Partner.

     The Partnership has completely funded its ten Projects at an aggregate
investment of $65.2 million.  Only three of the ten Projects, those with
Centocor, Inc. ("Centocor"), Genzyme Corporation ("Genzyme") and Synergen, Inc.
("Synergen"), are currently ongoing programs.  The remaining seven Projects
have either terminated or are near termination.

     On January 31, 1997, pursuant to the provisions of the Partnership
Purchase Option Agreement between Centocor and each limited partner, Centocor
exercised its option to purchase the limited partnership interests of Centocor
Partners III, L.P. ("CPIII"), including those owned by the Partnership.  The
Partnership received a one-time payment of $3,325,000 and will receive future
payments based on sales of certain products developed by CPIII.  In June 1997,
the Partnership and Centocor entered into an agreement to settle litigation
initiated by the Partnership in July 1995.  The settlement agreement provides
for, among other things, the method by which the payments to former limited
partners of CPIII will be made and for future cash payments to such former
limited partners to be made upon and after the effective date of the settlement
if certain events occur.  The settlement agreement will be reviewed at a
hearing scheduled for September 4, 1997, at which time it will be approved or
not.  Upon request, a copy of the settlement agreement as filed with the court
will be provided by the Purchaser or the Information Agent.

     The Partnership owns a limited partnership interest in Genzyme Development
Partners, L.P. ("GDP").  Of the products funded by GDP, only Seprafilm has been
approved for marketing in the United States by the Food and Drug Administration
("FDA").  A second product, Sepracoat, was not recommended for approval by an
FDA advisory panel on May 5, 1997.  GDP has entered into a joint venture to
manufacture and market Seprafilm, and shares profits of the joint venture with
Genzyme.  As of the date of this Offer, there has been no income resulting from
the joint venture and, as a result, no 


                                      13

<PAGE>

distributions have been made to the Partnership.  Genzyme Development 
Corporation II, the general partner of GDP, has indicated that no cash 
distributions will be made to its limited partners in 1997.  Genzyme has an 
option to purchase the outstanding partnership interests in GDP for a 
lump-sum cash payment and certain future royalty payments.
     
     The Partnership owns approximately 11% of the Class A limited partnership
interests in Synergen Clinical Partners, L.P. ("SCP").  In 1991, Synergen
formed SCP to fund the research and development of Interleukin-Receptor
Antagonist ("IL-lra") as a potential treatment of various inflammatory
diseases, with an emphasis on sepsis and rheumatoid arthritis.  Synergen
terminated its research and development program for sepsis in August 1994, and,
in December 1994, Synergen was acquired by Amgen Inc.  Research into the
potential use of IL-lra for rheumatoid arthritis is ongoing.  In February 1995,
a Class A limited partner of SCP commenced an action against the general
partner of SCP and others (the "Johnson Action").  The complaint sought damages
on behalf of a class including limited partners of SCP and limited partners of
the Partnership.  In February 1997, the parties announced a proposed settlement
of the Johnson Action, pursuant to which the defendants would pay $14,550,000,
less attorney's fees and costs, to class members, (of which approximately 11%
would go to the Partnership) and the limited partners' interests in SCP would
be terminated.  The settlement is conditioned on, among other things, the
approval of two-thirds of the current limited partnership interests in SCP and
final court approval.  The General Partner has concluded that the proposed
settlement is inadequate and not in the best interests of the Partnership.
Accordingly, the General Partner, on behalf of the Partnership, has opposed the
proposed settlement.  On June 19, 1997 the parties and the General Partner
advised the court that they had reached an agreement in principal to supplement
the proposed settlement and to resolve the Partnership's objection.  The
agreement was subject to final documentation.  The court ordered that such
documentation be filed by July 3, 1997.  On July 3, the parties informed the
court that they had been unable to reach agreement on final documentation.

     In addition to these investments, as of June 30, 1997, the Partnership
held cash, marketable securities, and warrants in the amounts indicated in the
abstracted portion of the Partnership 10-Q outlined below.

10.  SOURCE AND AMOUNT OF FUNDS

     Purchaser estimates that the maximum amount of funds required to 
purchase Units pursuant to the Offer and to pay related costs and expenses

that all amounts required for the purchase of Units and to pay related costs 
and expenses will be funded from existing cash balances of the Purchaser and 
the Funds.

11.  BACKGROUND OF THE OFFER

     BioRoyalties, L.L.C., a Delaware limited liability company, was formed 
in August 1997 to act as nominee for Pharmaceutical Royalties, L.L.C., a 
Delaware limited liability company formed in July 1996 and Pharmaceutical 
Royalty Investments Ltd., a Bermuda company formed in May 1996, each of which 
has been organized to invest in royalty interests and contingent payment 
rights ("CPRs") which derive cash payments based on the sale of 
pharmaceutical and biotechnology products.  The Purchaser and the Funds are 
managed by PPLLC.  As a result, it is the business of the PPLLC to identify, 
evaluate and acquire pharmaceutical royalty interests and CPRs.  The 
Partnership holds CPRs and limited partnership interests, the principal value 
of which is in CPRs resulting from the Partnership's investment in CPIII.

     PPLLC, on behalf of the Purchaser and the Funds, first formally 
expressed its interest in the assets of the Partnership on February 27, 1997 
in a letter addressed to the General Partner of the Partnership.  After a 
number of telephone calls to PaineWebber Development Corporation ("PWDC"), 
the Manager of the Partnership, in which PPLLC was unable to schedule a 
meeting to discuss its interest, on March 26, 1997, PPLLC made a written 
offer to PWDC to acquire all of the assets of the Partnership for $23 million 
in cash.  PWDC did not respond to PPLLC's offer.  Following the March 26 
letter, PPLLC had a number of telephone conversations with PWDC regarding its 
desire to meet in person to discuss the offer.  PWDC expressed a desire to 
delay the meetings until resolution of the litigation pending between the 
Partnership and Centocor regarding a dispute over the payments to be made to 
the holders of CPIII CPRs.

     During April, PPLLC had a number of conversations regarding PWDC's 
desire to delay discussions pending resolution of the litigation.  In an 
effort to accommodate the desires of PWDC, PPLLC agreed to delay meeting for 
a period of time.  As no announcement was made with respect to the litigation 

                                      18
<PAGE>

within the specified time period, PPLLC had a number of discussions and 
written correspondence with PWDC as to how to proceed.

     On May 13, 1997, PPLLC executed a confidentiality agreement with PWDC 
under which PWDC agreed to disclose to PPLLC the terms of a proposed 
settlement agreement in the litigation, so that PPLLC could make a more 
informed valuation of the assets of the Partnership.  On May 21, 1997, PPLLC 
met with PWDC, and was provided with a summary statement of the terms of the 
proposed settlement. The summary did not disclose all of the terms of the 
settlement, and PWDC refused to disclose the proposed settlement agreement 
until it had been filed with the Delaware court and made public.

     Following public disclosure of the settlement on June 6, 1997, PPLLC 
revised its valuation of the CPIII CPRs held by the Partnership.  On June 9, 
1997, PPLLC again met with PWDC in order to make a revised offer for the 
assets of the Partnership.  At this meeting, PPLLC offered $29 million in 
cash for all of the assets of the Partnership.  PWDC indicated to PPLLC that 
it would respond to PPLLC's offer within one week.  PWDC also indicated that 
the $29 million offer might be less than PWDC's opinion as to the value of 
the assets.

     On June 10, 1997, PPLLC sent PWDC a letter which included an analysis of 
the required rate of return on an asset such as the CPIII CPRs, taking into 
consideration that it is an asset with no liquid market and for which all of 
the value is dependent on the future sales of a single pharmaceutical 
product. On June 13, 1997, PWDC called PPLLC to inform PPLLC that PWDC still 
believed that the value of the assets was greater than the price offered by 
PPLLC.

     Since there remained a continuing disagreement on the value of the 
assets, PPLLC requested a meeting with PWDC to discuss possible approaches 
going forward.  On July 7, 1997, PPLLC met with PWDC again to discuss its 
valuation of the Partnership and to inform PWDC that since PPLLC believed 
that the offer it made was fair, the limited partners in the Partnership 
should decide for themselves whether the offer was adequate.  Consequently, 
PPLLC requested from PWDC the list of names and addresses of limited partners 
in order to make an offer to all Holders.

     On July 8 and 9, 1997, PPLLC had a number of discussions with PWDC 
regarding the conditions under which PWDC would provide the list of Holders. 
On July 11, 1997, PPLLC received an indication from PWDC that, consistent 
with the Partnership's policy for making available lists of limited partners, 
there were a number of undertakings that PPLLC would have to make in order to 
obtain the list.  On July 14, 1997, PPLLC sent to PWDC a modified version of 
these undertakings, and after an additional period of negotiations, arrived 
on July 23, 1997 at an agreement under which PWDC would provide the list to 
PPLLC.

     Following receipt of the list, PPLLC retained the Information Agent and 
commenced the Offer.

12.  PURPOSE OF THE OFFER; PLANS FOR THE PARTNERSHIP

     The purpose of the Offer is to enable the Purchaser and the Funds to 
acquire Units in the Partnership.  The Purchaser and the Funds are making 
this Offer because the Funds believe that the Units represent an attractive 
investment at the price offered.  There can be no assurance, however, that 
this belief is correct and, as a result, ownership of Units (either by the 
Purchaser, the Funds or Holders who retain their Units) remains a speculative 
investment. The Funds are acquiring the Units for investment purposes and do 
not currently intend to make any effort to change the management or 
operations of the Partnership and have no current plans for any extraordinary 
transaction regarding the Partnership.  Following the completion of the 
Offer, the Purchaser, the Funds and their affiliates may acquire additional 
Units.  Any such acquisition may be made through private purchases, through 
one or more future tender offers or by 

                                       19
<PAGE>

any other means deemed advisable, and may be at prices higher or lower than 
the price to be paid for the Units purchased in the Offer.

     Except as noted in this Offer to Purchase, Purchaser and the Funds have no
present plans or proposals that would result in an extraordinary corporate
transaction, such as a merger, reorganization, liquidation or sale or transfer
of a material amount of assets involving the Partnership or any subsidiary, or
any other material changes in the partnership's capitalization, composition,
distribution policy, structure or business.

     No appraisal rights are available to Holders in connection with the Offer.

13.  DISTRIBUTIONS TO LIMITED PARTNERS

     From inception through June 30, 1997, the Partnership distributed to its
limited partners $2,516 in cash and $7,206 in warrants and stock for total
distributions of $9,722 per Unit.  Revenues received from Partnership
investments in the first quarter arose mostly from non-recurring distributions
from product development programs and liquidation of equity positions.  During
the first six months of 1997, the Partnership received one-time payments
totaling $4,325,000 or $520 per Unit.  Of this amount, the Partnership received
a one-time payment of $3,325,000, or approximately $400 per Unit, from its
investment in CPIII.  The Partnership also received proceeds of $1,000,000, or
approximately $120 per Unit, from the sale of its warrant in OEC Medical
Systems, Inc.

<PAGE>

     The foregoing conditions are for the sole benefit of Purchaser and its 
affiliates and may be asserted by Purchaser regardless of the circumstances 
(other than any action or inaction by Parent, Purchaser or any of their 
affiliates) giving rise to any such condition or may be waived by Purchaser, 
in whole or in part, from time to time in its sole discretion.  The failure 
by Purchaser at any time to exercise any of the foregoing rights shall not be 
deemed a waiver of any such right and each such right shall be deemed an 
ongoing right and may be asserted at any time and from time to time.  Any 
reasonable determination by Purchaser concerning any of the events described 
herein shall be final and binding.

15.  CERTAIN LEGAL MATTERS

     The Purchaser is not aware of any license or other regulatory permit which
appears to be material to the business of the Partnership and that might be
adversely affected by the Purchaser's acquisition of Units pursuant to the
Offer, any approval or other action by any domestic or foreign governmental or
administrative agency that would be required prior to the acquisition of Units
by the Purchaser pursuant to the Offer, or any state takeover statute that is
applicable to the Offer.  Should any such approval or other action be required,
or any such state takeover statute be applicable, the Purchaser will evaluate
at such time whether such approval or action will be sought or compliance with
such takeover statute will be effected.  There can be no assurance that any
such approval, action, or compliance, if needed, would be obtained or effected
or, if obtained or effected, would be obtained or effected without substantial
conditions or adverse consequences.  The Purchaser's obligation to purchase and
pay for the tendering Units is subject to certain conditions, including
conditions relating to the legal matters discussed herein.  Section 14 above
for certain conditions to the offer.

     APPRAISAL RIGHTS.  Holders will not have appraisal rights as a result of
the Offer.

     MARGIN REQUIREMENTS.  The Units are not "margin securities" under the
regulations of the Board of Governors and the Federal Reserve System and,
accordingly, those regulations generally are not applicable to the Offer.

     ANTITRUST.  Under the Hart-Scott-Rodino Antitrust Improvements Act of
1976, as amended (the "HSR Act"), and the rules and regulations that have been
promulgated thereunder by the Federal Trade Commission (the "FTC"), certain
acquisition transactions may not be consummated until certain information and
documentary material has been furnished for review by the Antitrust Division of
the Department of Justice (the "Antitrust Division") and the FTC and certain
waiting period requirements have been satisfied.  The Purchaser does not
currently believe any filing is required under the HSR Act with respect to its
acquisition of Units contemplated by the Offer.

     In addition, the Antitrust Division and the FTC scrutinize the legality of
acquisitions, mergers, and other commercial transactions.  At any time before
or after the Purchaser's purchase of Units, the Antitrust Division of the FTC
could take such action as either deems necessary or desirable in the public
interest regarding such purchase, including seeking to enjoin the purchase of
Units pursuant to the Offer, the divestiture of Units purchased thereunder or
the divestiture of substantial assets of the Partnership.  Private parties as
well as state attorneys general may also bring legal actions under the
antitrust laws under certain circumstances.  There can be no assurance that a
challenge to the Offer on antitrust grounds will not be made or, if such
challenge is made, what the result will be.

16.  FEES AND EXPENSES

     Purchaser has retained The Herman Group to act as the Information Agent
and Depositary in connection with the Offer.  The Herman Group will receive
reasonable and customary compensation for its services, will be reimbursed for
certain reasonable out-of-pocket expenses and will be indemnified against


                                       22

<PAGE>

certain liabilities and expenses in connection therewith, including certain
liabilities under the federal securities laws.

     Except as set forth above, Purchaser will not pay any fees or commissions
to any broker or dealer or other person for soliciting tenders of Units
pursuant to the Offer.  Brokers, dealers, commercial banks and trust companies
will be reimbursed by Purchaser for customary mailing and handling expenses
incurred by them in forwarding the offering materials to their customers.

17.  MISCELLANEOUS

     The Offer is not being made to (nor will tenders be accepted from or on
behalf of) Holders residing in any jurisdiction in which the making of the
Offer or the acceptance thereof would not be in compliance with the securities,
blue sky or other laws of the jurisdiction.  However, Purchaser may, in its
discretion, take such action as it may deem necessary to make the Offer in any
jurisdiction and extend the Offer to Holders.  In any jurisdiction where the
securities, blue sky or other laws require the Offer to be made by a licensed
broker or dealer, the Offer will be deemed to be made on behalf of Purchaser by
one or more registered brokers or dealers that are licensed under the laws of
the jurisdiction.

THE OFFER, PRORATION PERIOD AND WITHDRAWAL RIGHTS WILL EXPIRE AT MIDNIGHT, 
EASTERN TIME, ON SEPTEMBER 12, 1997 (THE "EXPIRATION DATE") UNLESS SUCH OFFER 
IS EXTENDED.

     The undersigned hereby tender(s) to BioRoyalties, L.L.C., a Delaware 
limited liability company (the "Purchaser"), the number of units of limited 
partnership interest ("Units") in PaineWebber R&D Partners II, L.P., a 
Delaware limited partnership (the "Partnership"), specified above, pursuant 
to the Purchaser's offer to purchase any and all of the 8,257 issued and 
outstanding Units at a purchase price of $3,650 per Unit, net to the seller 
in cash (the "Purchase Price"), without interest thereon, upon the terms and 
subject to the conditions set forth in the Offer to Purchase dated August 15, 
1997 (the "Offer to Purchase") and this Letter of Transmittal (the "Letter of 
Transmittal"), which, together with the Offer to Purchase and any 
supplements, modifications or amendments thereto, constitute the Offer (the 
"Offer"), all as more fully described in the Offer to Purchase. HOLDERS WHO 
TENDER THEIR UNITS WILL NOT BE OBLIGATED TO PAY ANY COMMISSIONS OR 
PARTNERSHIP TRANSFER FEES. Receipt of the Offer to Purchase is hereby 
acknowledged. Capitalized terms used but not defined herein have the 
respective meanings ascribed to them in the Offer to Purchase.

     By executing and delivering this Letter of Transmittal, a tendering 
Holder irrevocably appoints designees of Purchaser as his or her 
attorneys-in-fact and proxies, with full power of substitution, to the full 
extent of the Holder's rights with respect to the Units (and with respect to 
any and all other securities issued or issuable in respect of such Units on 
or after the date hereof) tendered by the Holder. All such powers of attorney 
and proxies will be considered coupled with an interest in the tendered Units 
and all prior powers of attorney and proxies given by the Holder with respect 
to the Units will be revoked, without further action, and no subsequent 
powers of attorney and proxies will be given (and, if given, will not be 
deemed effective) by the Holder. Designees of Purchaser will be empowered to 
exercise all voting and other rights of the Holder with respect to such Units 
as they in their sole discretion may deem proper, including, without 
limitation, in respect of any annual or special meeting of the Holders, or 
any adjournment or postponement of any such meeting, or in connection with 
any action by written consent in lieu of any such meeting or otherwise. 
Purchaser reserves the absolute right to require that, in order for Units to 
be validly tendered, immediately upon Purchaser's acceptance for payment of 
the Units, Purchaser must be able to exercise full voting and other rights 
with respect to the Units.

    Pursuant to such appointment as proxies and attorneys-in-fact, the 
Purchaser and its designees each will have the power, among other things, (i) 
to seek to transfer ownership of such Units on the books and records of the 
Partnership (and execute and deliver any accompanying evidences of transfer 
and authenticity any of them may deem necessary or appropriate in connection 
therewith, including, without limitation, any documents or instruments 
required to be executed under the Partnership Agreement or a "Transferor's 
(Sellers) Application for Transfer" created by the NASD, if required), (ii) 
upon receipt by the Information Agent/Depositary (as the tendering Holder's 
agent) of the Purchase Price, to be allocated Tax Credits and tax losses and 
to receive any and all distributions made or declared by the Partnership 
after June 30, 1997 in respect of the Units tendered by such Holder and 
accepted for payment by the Purchaser, regardless of the fact that the record 
date for any such distribution may be a date prior to or after the Expiration 
Date, (iii) the right to transfer or assign, in whole or from time to time in 
part, to any third party, the right to purchase Units tendered pursuant to 
the Offer, together with its rights under the Letter of Transmittal, but any 
such transfer or assignment will not relieve the assigned party of its 
obligations under the Offer or prejudice the right of tendering Holders to 
receive payment for Units validly tendered and accepted for payment pursuant 
to the Offer, and (iv) to execute and deliver to the Partnership, the General 
Partner and/or designee (as the case may be) a change of address form 
instructing the Partnership to send any and all future distributions to which 
the Purchaser is entitled pursuant to the terms of the Offer in respect of 
tendered Units to the address specified in such form and to endorse any check 
payable to or upon the order of such Holder representing a distribution, if 
any, to which the Purchaser is entitled pursuant to the terms of the Offer, 
in each case on behalf of the tendering Holder. This power of attorney shall 
not be affected by the subsequent mental disability of the Holder, and the 
Purchaser shall not be required to post bond in any nature in connection with 
this power of attorney. The Purchaser may assign such power of attorney to 
any person with or without assigning the related Units with respect to which 
such power of attorney was granted. If legal title to the Units is held 
through an IRA or KEOGH or similar account, the Holder understands that this 
Letter of Transmittal must be signed by the custodian of such IRA or KEOGH 
account and the Holder hereby authorizes and directs the custodian of 
such IRA or KEOGH to confirm this Letter of Transmittal.

     By executing this Letter of Transmittal, the undersigned represents that 
either (a) the undersigned is not a plan subject to Title I of the Employee 
Retirement Income Security Act of 1974, as amended ("ERISA") or Section 4975 
of the Internal Revenue Code of 1986, as amended (the "Code), or an entity 
deemed to hold "plan assets" within the meaning of 29 C.F.R. Section 
2510.3-101 of any such plan; or (b) the tender and acceptance of Units 
pursuant to the Offer will not result in a non-exempt prohibited transaction 
under Section 406 of ERISA or Section 4975 of the Code.

     By executing this Letter of Transmittal, the undersigned represents that this transfer has not been effected through an
established securities market or through a broker-dealer or matching agent which makes a market in Units or which provides a
widely available, regular and on-gong opportunity to the Holder of Units to sell or exchange their Units through a public means
of obtaining or providing information of offers to buy, sell or exchange Units.

     The undersigned recognizes that if proration is required pursuant to the terms of the Offer, the Purchaser will accept for
payment from among those Units validly tendered and not properly withdrawn on or prior to the Expiration Date, the maximum number
of Units permitted pursuant to the Offer on a pro rata basis with adjustments to avoid purchases which would violate the terms of
the Offer, based upon the number of Units validly tendered prior to the Expiration Date and not properly withdrawn.

     The undersigned understands that a tender of Units to the Purchaser will constitute a binding agreement between the
undersigned and the Purchaser upon the terms and subject to the conditions of the Offer. The undersigned recognizes that under
certain circumstances set forth in Section 2 ("Proration: Acceptance for Payment for Units") and Section 14 ("Conditions of the
Offer") of the Offer to Purchase, the Purchaser may not be required to accept for payment any of the Units tendered hereby. In
such event, the undersigned understands that any Letter of Transmittal for Units not accepted for payment will be destroyed by
the Purchaser. Except as stated in Section 4 ("Withdrawal Rights") of the Offer to Purchaser, this tender is irrevocable,
provided Units tendered pursuant to the Offer may be withdrawn at any time prior to the Expiration Date. The undersigned
acknowledges that (i) upon acceptance of, and payment for, tendered Units, the undersigned shall no longer be entitled to any
benefits as a Holder.

4.   TAX CERTIFICATIONS.  Holders tendering Units to the Purchaser pursuant 
     to the Offer must certify correctness of the address as printed or 
     corrected on the front of the Letter of Transmittal and his, her or its 
     Taxpayer Identification Number ("TIN") as inserted in the Signature Box.

     SUBSTITUTE FORM W-9.

     PART (i), TAXPAYER IDENTIFICATION NUMBER - The persons signing this Letter 
     of Transmittal must provide to the Purchaser the Holder's correct TIN and 
     certify its correctness as inserted in the Signature Box, under penalties 
     of perjury. If a correct TIN is not provided, penalties may be imposed by 
     the Internal Revenue Service ("IRS"), in addition to the Holder's being 
     subject to Backup Withholding.

     PART (ii), BACKUP WITHHOLDING - in order to avoid 31% federal income tax 
     Backup Withholding, the person signing this Letter of Transmittal must 
     certify, under penalties of perjury, that such Holder is not subject to 
     Backup Withholding. Certain Holders (including, among others, all 
     Corporations and certain exempt non-profit organizations) are not subject
     to Backup Withholding. Backup Withholding is not an additional tax. If 
     withholding results in an overpayment of taxes, a refund may be obtained 
     from the IRS. DO NOT CHECK THE BOX IN THE SUBSTITUTE FORM W-9 PART (ii), 
     UNLESS YOU HAVE BEEN NOTIFIED BY THE IRS THAT YOU ARE SUBJECT TO BACKUP 
     WITHHOLDING.

     When Determining the TIN to Be Furnished, Please Refer to the Following 
     NOTE as a Guideline:

     INDIVIDUAL ACCOUNTS should reflect their own TIN. JOINT ACCOUNTS should 
     reflect the TIN of the person whose name appears first. TRUST ACCOUNTS 
     should reflect the TIN assigned to the Trust. IRA CUSTODIAL ACCOUNTS should
     reflect the TIN of the custodian (not necessary to obtain). CUSTODIAL 
     ACCOUNTS FOR THE BENEFIT OF MINORS should reflect the TIN of the minor. 
     CORPORATIONS OR OTHER BUSINESS ENTITIES should reflect the TIN assigned to
     that entity. 

5.   VALIDITY OF LETTER OF TRANSMITTAL.  All questions as to the validity, form,
     eligibility (including time of receipt) and acceptance of a Letter of 
     Transmittal will be determined by the Purchaser and such determination will
     be final and binding. The Letter of Transmittal will not be valid until any
     irregularities have been cured or waived. Neither the Purchaser nor The 
     Herman Group, Inc. is under any duty to give notification of defects in a 
     Letter of Transmittal and neither will incur liability for failure to give 
     such notification.

6.   CONDITIONAL TENDERS.  No alternative, conditional or contingent tenders 
     will be accepted.

7.   ASSIGNEE STATUS.  Assignees of Holders must provide documentation to the 
     Information Agent/Depositary which demonstrates, to the satisfaction of the
     Purchaser, such person's status as an Assignee.

                                                              August 15, 1997


                 OFFER TO PURCHASE AT $3,650 PER UNIT IN CASH

Dear Limited Partner of PaineWebber R&D Partners II, L.P.:

BioRoyalties, L.L.C., a Delaware limited liability company (the "Purchaser"),
is offering to purchase from holders (each a "Holder") any and all of the 8,257
outstanding units of limited partnership interest (the "Units") in PaineWebber
R&D Partners II, L.P. (the "Partnership") at a cash purchase price of $3,650
per Unit (the "Purchase Price").  The terms and conditions of the offer are set
forth in the Offer to Purchase, which is enclosed with this letter.  IT IS
IMPORTANT THAT YOU READ THE ENCLOSED MATERIAL CAREFULLY IN ORDER TO EVALUATE
THE OFFER.

From the inception of the Partnership in 1987 through the second quarter of
this year, Holders have received cumulative distributions totaling $9,722 per
Unit, of which $2,516 were in cash and $7,206 were in stock and warrants.  The
Purchase Price, together with cumulative distributions to date, will enable a
Holder who purchased Units pursuant to the original offering in 1987 to recover
the remainder of his or her original $10,000 per Unit investment and realize a
$3,372 profit.  In the alternative, a Holder may need to wait an additional 10-
12 years to realize the full value of the assets held by the Partnership.

Following are some important features of the Offer:

- -  LIQUIDITY OPPORTUNITY.  The Offer provides each Holder the opportunity to
   liquidate his or her investment in the Partnership without transfer fees 
   and transaction costs generally incurred in secondary market sales (which 
   can range from 5% to 8.75% of the sale price).  Although there are limited 
   resale mechanisms available to Holders through partnership matching 
   services, there is no formal trading market for the Units.  According to 
   the Partnership's Annual Report on Form 10-K for the fiscal year ended 
   December 31, "there is no established trading market for the limited 
   partnership interests, and no such market is expected to develop."

- -  PURCHASE PRICE GREATER THAN GENERAL PARTNER'S JULY 1996 VALUATION FOR
   ERISA PURPOSES.  The aggregate Purchase Price is greater than the $29 
   million valuation of the Partnership prepared by the General Partner in 
   July 1996 for ERISA purposes.  In addition, since the date of the General 
   Partner's valuation, the Partnership has distributed approximately $7.7 
   million in cash.

- -  PREMIUM TO HISTORICAL PRICES.  The Purchase Price represents a premium of
   46% to the most recent and highest selling price ($2,500 per Unit) of a 
   Unit traded on the Chicago Partnership Board or in any other transaction 
   of which Purchaser is aware.

- -  POTENTIAL TAX BENEFIT, ENHANCED BY CHANGE IN CAPITAL GAIN RATES TO 20%.
   Each holder is generally taxable on his or her allocable share of 
   Partnership profits, a portion of which are ordinary income.  Ordinary 
   income is taxed to individuals at rates of up to 39.6%.  A portion of the 
   gain resulting from the sale of a Unit should be taxed to non-corporate 
   Holders at capital gain rates (currently 20% for most individuals) 
   disposing of capital assets held more than 18 months, possibly resulting 
   in tax savings.  In addition, the sale of a Unit may enable a Holder to 
   use previously disallowed passive loss carryforwards, accelerating their 
   recognition.  THE PURCHASER IS NOT EXPRESSING AN OPINION AS TO THE TAX 
   CONSEQUENCES OF TENDERING UNITS.  Holders are strongly advised to consult 
   their tax advisors with respect to the tax consequences of accepting the 
   Offer.

- -  RESOLUTION OF LITIGATION.  On June 6, 1997, Centocor and the Partnership
   reached an agreement to settle a dispute over payments owed to investors 
   in Centocor Partners III, L.P.  The settlement is subject to court 
   approval, for which a hearing is scheduled on September 4, 1997.  If 
   approved, the agreement would result in one-time cash payments per Unit of 
   approximately $420 in 1997, $280 in 1998, and $95 if and when ReoPro is 
   approved for marketing in Japan. The Partnership is also entitled to 
   receive payments based on the sales of ReoPro over the next 10 years, 
   which have been revised under the settlement agreement.  The Purchaser has 
   considered the value of these payments in determining the Purchase Price.

- -  SIMPLIFIED TAX RETURNS.  The Offer may be attractive to certain Holders
   who wish in the future to avoid the expenses, delays and complications of 
   filing complex income tax returns resulting from Form K-1s necessitated by 
   ownership of  Units.

- -  VALUE DEPENDENT ON ONE PRODUCT.  The Purchaser believes that a substantial
   portion of the value of the Partnership is attributable to the right to 
   receive cash payments based on the future sales of ReoPro.  There are at 
   least four other products having a mechanism of action similar to that of 
   ReoPro that are in clinical development for the same or similar 
   indications.  There can be no assurance that the sales of ReoPro will not 
   be adversely affected by these products.

- -  POSSIBLE REGULATORY ISSUES.  The Partnership's Centocor CPRs may be
   considered securities under the Investment Company Act of 1940 (the 
   "Act").  As a result, the Partnership will need to determine whether it is 
   subject to the Act and possible implications for its future business 
   strategy.  One possible way to avoid issues that might arise under the Act 
   is to distribute the CPRs. In a partnership with similar investments, 
   PaineWebber R&D Partners, L.P., the partnership distributed to its limited 
   partners securities similar to the CPRs. If the General Partner were to 
   distribute to each Holder his or her PRO RATA share of CPRs, each Holder 
   would receive an asset for which there is not likely to be a market, and 
   for which the value depends exclusively on the sales of a single 
   pharmaceutical product over a 10 year period.  The Purchaser believes that 
   if this strategy were pursued it would negatively impact the ability of a 
   Holder to maximize the value of his or her interest.

In purchasing these Units, BioRoyalties is assuming the performance risk of
ReoPro over the next several years.  The Purchaser is engaged in a long-term
investment program to create a diversified portfolio of assets that derive cash
flow from the sales of biotechnology and pharmaceutical drugs.  The Purchaser's
financial structure and strategic plan are geared to address risk factors such
as illiquidity, single-product risk, competition, and other factors which
affect the value of assets such as those held by the Partnership, and its
financial returns are largely dependent on the success of its overall program,
rather than any individual investment.

Please review the enclosed Offer to Purchase carefully.  As this Offer is
available for a limited period of time, we urge you to tender your Units
promptly by completing and signing page 2 of the Letter of Transmittal and
returning the Letter of Transmittal in the enclosed postage-paid envelope or by
facsimile to the information agent.  The Offer will expire at 12:00 midnight,
New York City time, September 12, 1997.

If you have any questions or need assistance, please call the Herman Group at
(800) 243-3399, or call BioRoyalties, L.L.C. at (800) 600-1450.

                                         Sincerely,

                                         BioRoyalties, L.L.C.
